(Background to this disclosure)
Prior to the explanation of the embodiments and the like of the present disclosure, the circumstances leading to the present disclosure will be described.

Patent Document 1 discloses a feeder (bulk feeder) into which a case (bulk cassette) to which a barcode is attached is inserted. The case houses electronic component chips (components) in bulk. The central controller reads the barcode of the case inserted in the feeder with the barcode reader, and if the information of the electronic component chip indicated by the barcode matches the information of the specified electronic component chip, the shutter is closed. The shutter solenoid that locks to the state is turned on to open and close the shutter, and the shutter opening / closing plate is unlocked. Along with this, the shutter opening / closing lever connected to the shutter opening / closing plate is pulled (driven) by the spring, so that the shutter opening / closing plate slides and the shutter opens. As a result, the electronic component chip in the case is supplied to the chip feeding unit.

Further, in Patent Document 1, when the bulk cassette inserted in the bulk feeder is replaced, the electronic component chip supplied from the bulk cassette passes through a chip feeding path (conveying unit) for moving the electronic component chip to a predetermined position. It is disclosed that the bulk cassette is taken out and a new bulk cassette is inserted into the bulk cuffer when the component chip is no longer detected.

As described above, in Patent Document 1, since the barcode is read by the barcode reader, it takes time and effort, which may affect the productivity. For example, if you have a large number of cases, you need to read the barcode in each case. In other words, it is necessary to move the barcode reader to the position of each case. When reading barcodes in such a large number of cases, it is particularly troublesome and there is a concern that productivity will decrease. Therefore, the inventors of the present application have diligently studied a mounting system capable of suppressing a decrease in productivity, and devised a mounting system described below.

Further, in each figure, the same reference numerals may be given to substantially the same configurations, and duplicate explanations may be omitted or simplified. Further, even when the same object is shown in each figure, the scale may be changed for convenience.

Further, in the present specification and the drawings, the X-axis, the Y-axis, and the Z-axis indicate the three axes of the three-dimensional Cartesian coordinate system. In each embodiment, the Z axis is an axis parallel to the direction in which the feeder and the case are overlapped. The X-axis and the Y-axis are axes that are substantially orthogonal to the Z-axis. The feeder is elongated and the X-axis is an axis parallel to the longitudinal direction of the feeder. Further, in the present specification, "planar view" means a case of viewing from the Z-axis direction.

Further, in the present specification, terms indicating relationships between elements such as match, equality, and parallel, terms indicating the shape of elements such as plate and rectangle, numerical values, and numerical ranges are strict. It is not an expression that expresses only a meaning, but an expression that means that a substantially equivalent range, for example, a difference of about several percent is included.

[1-1. Implementation system overview]
The configuration of the mounting system 1 according to the present embodiment will be described with reference to FIGS. 1A to 12. FIG. 1A is a diagram showing a schematic configuration of a mounting system 1 according to the present embodiment. First, the outline of the mounting system 1 will be described with reference to FIG. 1A.

As shown in FIG. 1A, the mounting system 1 of the present embodiment includes an integrated control device 50, a first control device 50a, a second control device 50b, a transfer robot 60, a supply unit 80, and a parts storage. It includes a W and a mounting line 90 including a plurality of component mounting devices 100. Further, the mounting system 1 includes three areas, a storage area A1, a preparation area A2, and a mounting area A3. Although the details will be described later, the case 10 has a parts accommodating portion for accommodating parts in a bulk state, which is an example of the first accommodating portion, and the attachment 30 conveys the parts supplied from the case 10. It has a function and is an example of a second accommodating portion. The component is, for example, an electronic component such as a resistor or a capacitor, but the component is not limited to this, and may be any component that can be mounted on a substrate.

The storage area A1 is an area for storing the case 10 and the attachment 30. The storage area A1 includes, for example, a parts storage W. At least one of the case 10, the attachment 30, and the attachment 30 to which the case 10 is attached is stored in the parts storage W. Further, in the parts storage W, the tag information stored in the RF tag can be read from the RF (Radio Frequency) tag attached to each of the case 10 and the attachment 30, and the tag information to be written in the RF tag can be read. A reader / writer RW for writing is attached. The reader / writer RW is fixed and can simultaneously acquire tag information transmitted from a plurality of RF tags. Further, the reader / writer RW can simultaneously transmit the tag information to be written in the RF tag to a plurality of RF tags.

The tag information includes information about the parts housed in the case 10 when the RF tag is attached to the case 10. For example, the tag information includes at least information indicating the type of a part (identification information), information indicating a quantity (remaining number), information indicating an expiration date, or an identification code of the tag itself (for example, Electronic Product Code: EPC). Including one. The information indicating the quantity is the current quantity.

Further, the tag information includes at least one such as the identification information of the attachment 30 and the usage history when the RF tag is attached to the attachment 30.

The tag information read by the reader / writer RW is managed by the integrated control device 50.

Note that FIG. 1A illustrates an example in which the storage area A1 is separated from the mounting area A3, but the present invention is not limited to this. For example, the storage area A1 may be provided as a part of the mounting area A3. For example, the component storage W may be included in the mounting area A3. Further, for example, the mounting line 90 may include a component storage W. When the component storage W is included in the mounting line 90, the case 10 and the attachment 30 can be directly supplied from the component storage W to the device in the mounting line 90. That is, the case 10 and the attachment 30 can be supplied without going through the preparation area A2.

The preparation area A2 is an area for preparing in advance what is used in the mounting line 90 of the mounting area A3. For example, the supply unit 80 to be mounted on the mounting line 90 is prepared in advance. The supply unit 80 includes, for example, a dolly 70 having a holding portion 71, a feeder main body portion 40 held by the holding portion 71, an attachment 30 attached to the feeder main body portion 40, and a case 10 attached to the attachment 30. .. In the present embodiment, the dolly 70 includes a plurality of holding portions 71. Note that FIG. 1A shows one of the plurality of holding portions 71. In this case, for example, a carriage 70 to which the feeder main body 40 and the attachment 30 are attached is arranged in the preparation area A2. The second control device 50b is used in the next production by instructing the transfer robot 60 to attach the case 10 for accommodating the parts used in the next production in the mounting line 90 to the attachment 30 attached to the carriage 70. Supply unit 80 is prepared in advance. In the preparation area A2, not only the trolley 70 but also a holding device that can be connected to the trolley 70 may be prepared as long as the case 10 and the like can be held.

Further, the dolly 70 is provided with a reading device 130. The reading device 130 is fixed to, for example, the holding portion 71 of the carriage 70. Further, in the preparation area A2, the supply unit 80 may be connected to an external power source. Alternatively, the supply unit 80 may include a power supply unit inside (for example, inside the carriage 70). As a result, the second control device 50b can confirm whether the case 10, the attachment 30, and the feeder main body 40 attached to the trolley 70 are in the correct combination by using the reading device 130 provided on the trolley 70. can. Further, when a set of a plurality of cases 10, attachments 30 and feeder main body 40 is arranged on one carriage 70, the second control device 50b can confirm whether the mounting positions thereof are correct.

In the preparation area A2, a case 10 for accommodating parts that may be replenished may be transported from the parts storage W and stored. As a result, when the case 10 is replenished, the time can be shortened as compared with the case of transporting the case 10 from the storage area A1.

The mounting area A3 is an area where the mounting line 90 is arranged. The mounting area A3 and the preparation area A2 may be arranged in the same space. The mounting line 90 produces a mounting board by mounting the components housed in the case 10 on the board carried in from the upstream side, and carries out the produced mounting board to the downstream side. The mounting line 90 is realized by various devices that supply a substrate, perform solder printing work, component mounting work, reflow work, and the like. The component mounting work is performed by the component mounting device 100.

The integrated control device 50 is connected to the first control device 50a and the second control device 50b, and aggregates and manages information on each component of the mounting system 1. The first control device 50a controls each component of the mounting line 90. The first control device 50a controls the production of the mounting line 90, for example, based on the production plan. Even if each component of the mounting line 90 is controlled by the first control device 50a and a control device (not shown) provided in each component of the mounting line 90 (for example, the component mounting device 100). good. When the remaining number of parts in the case 10 of the supply unit 80 mounted on the mounting line 90 becomes a predetermined number or less, the first control device 50a transmits a supply request for parts to the integrated control device 50. The second control device 50b receives the supply request for the parts from the integrated control device 50, outputs the supply instruction to the transfer robot 60, and supplies the parts. Specifically, the second control device 50b replenishes the transfer robot 60 with a position in the storage area A1 of the case 10 to be replenished, a movement path of the transfer robot 60, and a position for replenishing the case 10 (for example,). The position in the mounting line 90, the position in the component mounting device 100, the position in the supply unit 80, and the position in the preparation area A2) are instructed. Based on the instruction from the second control device 50b, the transfer robot 60 conveys the case 10 accommodating the parts to be replenished from the storage area A1 to the mounting line 90, and transfers the case 10 of the supply unit 80 to the new case 10. Exchange. Specifically, the transfer robot 60 collects the case 10 of the supply unit 80 and attaches a new case 10.

Further, when the case 10 attached to the supply unit 80 is changed to the case 10 filled with other types of parts, the second control device 50b controls the transfer robot 60 to supply the case 10 attached to the mounting line 90. The case 10 and the attachment 30 of the unit 80 are replaced.

The transfer robot 60 is a self-propelled robot that conveys the case 10 and the attachment 30 under the control of the second control device 50b. Here, the transfer robot 60 will be described with reference to FIG. 1C. FIG. 1C is a diagram showing a configuration of a transfer robot 60 according to the present embodiment.

As shown in FIG. 1C, the transfer robot 60 is composed of, for example, a traveling unit 62, a storage unit 63, and a robot arm 61. The traveling unit 62 includes wheels and a motor for driving the wheels. The case 10 and the attachment 30 are stored in the storage unit 63. The storage unit 63 is formed with, for example, a holding unit 63a for holding each of the plurality of cases 10 and the attachment 30. The transfer robot 60 can transfer the plurality of cases 10 and the attachments 30 at one time by moving the plurality of cases 10 and the attachments 30 in a state of being stored in the storage unit 63. A robot arm 61 is provided above the storage unit 63. The tip of the robot arm 61 is formed so that the case 10 and the attachment 30 can be gripped. The transfer robot 60 mounts the case 10 and the attachment 30 stored in the storage unit 63 by the robot arm 61 on the component mounting device 100. As a result, the transfer robot 60 can attach the case 10 and the attachment 30 to the plurality of component mounting devices 100 by one transfer. The shape and transfer method of the transfer robot 60 are examples, and are not limited to the above. The transport robot 60 may transport the object by supporting or gripping the object with the robot arm 61. For example, the dolly 70 or the supply unit 80 may be supported or gripped and conveyed. For example, when the second control device 50b collectively changes the types of parts of the case 10 of the supply unit 80 mounted on the mounting line 90, the second control device 50b controls the transfer robot 60 and prepares the supply unit in advance. The 80 is conveyed and replaced with the supply unit 80 attached to the mounting line 90.

As described above, the mounting system 1 is a system in which the integrated control device 50 manages the supply of parts and the change of the type of parts.

Here, the component mounting device 100 to which the supply unit 80 is attached will be described with reference to FIG. FIG. 2 is a diagram showing a configuration of a component mounting device 100 according to the present embodiment. An example in which the component mounting device 100 is a device for mounting components on the board 103 will be described. The component mounting device 100 has a function of taking out components from a feeder that supplies the components and transferring and mounting the components on the board 103. The substrate 103 is an example of an object on which components are mounted.

As shown in FIG. 2, the component mounting device 100 includes a supply unit 80, a base 101, a board transfer mechanism 102, a component mounting mechanism 108 including a mounting head 107, a board recognition camera 109, and a component recognition camera 110. And a power supply unit 111 (see FIG. 1B).

The substrate transfer mechanism 102 is arranged near the center of the base 101 along the X axis (in the transfer direction of the substrate 103). The board transfer mechanism 102 transports the board 103 carried in from the upstream side in the direction along the X-axis, and positions and holds the board 103 on the mounting stage set for executing the component mounting work. The supply unit 80 is detachably mounted on a supply unit mounting portion (not shown) of the base 101, which is the main body of the component mounting device 100. More specifically, in the supply unit 80, a dolly 70 constituting the supply unit 80 is mounted on the supply unit mounting portion. In the present embodiment, the supply unit mounting portions are provided on both sides of the substrate transfer mechanism 102, and the supply unit 80 is also arranged on both sides of the substrate transfer mechanism 102. A plurality of feeders 20 can be arranged in parallel along the Y axis in each supply unit 80, and at least one feeder 20 (bulk feeder) is mounted in parallel. The feeder 20 includes, for example, a feeder main body 40 and an attachment 30. The substrate transfer mechanism 102 is an example of a substrate transfer unit. Further, when the supply unit 80 is mounted on the base 101, each functional unit (for example, a vibration generating unit 41, a driving unit 45, a reading device 130, etc., which will be described later) and a power supply unit 111 of the supply unit 80 are electrically connected. Power is supplied from the power supply unit 111 to each functional unit of the supply unit 80.

The feeder 20 arranged in the supply unit 80 supplies the components to the take-out position by the mounting head 107 of the component mounting mechanism 108. The mounting head 107 is an example of a component mounting unit.

An X-axis moving table 105 provided with a linear drive mechanism is arranged in the X-axis direction on the upper surface of the base 101 at the end in the minus direction of the Y-axis, and the X-axis moving table 105 is similarly linearly driven. Two Y-axis moving tables 106 equipped with a mechanism are movably connected in the X-axis direction. A mounting head 107 is mounted on each of the two Y-axis moving tables 106 so as to be movable in the Y-axis direction.

The mounting head 107 mounts (mounts) the components held by the feeder 20 arranged on the supply unit 80 on the board 103. The mounting head 107 is based on, for example, a determination result of correctness of a component based on two tag information (for example, information acquired from RF tags T2 and T3 described later) in the integrated control device 50 or the first control device 50a. , The component is mounted on the board 103. The determination result is the determination result regarding the remaining number of parts, whether or not the information (identification information) indicating the type of the parts accommodated in the replaced case 10 is appropriate, and whether or not the arrangement of the case 10 in the supply unit 80 is correct or not. Judgment results, etc., but are not limited to this. The integrated control device 50 or the first control device 50a is an example of the determination unit.

The mounting head 107 is equipped with a component suction nozzle (not shown) that can suck and hold the component and raise and lower it individually. The mounting head 107 includes a Z-axis elevating mechanism for raising and lowering the component suction nozzle and a θ-axis rotation mechanism for rotating the component suction nozzle around the nozzle axis.

By driving the X-axis moving table 105 and the Y-axis moving table 106, the mounting head 107 moves in the X-axis direction and the Y-axis direction. As a result, the two mounting heads 107 take out the parts from the take-out positions of the feeders 20 arranged in the corresponding supply units 80 by the parts suction nozzles. The component mounting mechanism 108 is configured by the substrate transfer mechanism 102, the X-axis moving table 105, the Y-axis moving table 106, and the mounting head 107.

A component recognition camera 110 is arranged between each of the upper and lower carriages 70 and the board transfer mechanism 102. When the mounting head 107 from which the component is taken out from the feeder 20 arranged in the supply unit 80 moves above the component recognition camera 110, the component recognition camera 110 takes an image of the component held by the mounting head 107. By recognizing this imaging result by image recognition of a processing unit (not shown), component identification and position detection are performed.

The mounting head 107 is equipped with a board recognition camera 109 that is located on the lower surface side of the Y-axis moving table 106 and moves integrally with the mounting head 107. When the mounting head 107 moves, the board recognition camera 109 moves above the board 103 positioned by the board transfer mechanism 102 and takes an image of the board 103. The position of the substrate 103 is detected by recognizing the image pickup result by the image recognition of the processing unit in the same manner.

The power supply unit 111 supplies electric power to each functional unit of the component mounting device 100. The power supply unit 111 supplies electric power to the supply unit 80 arranged in the substrate transfer mechanism 102, for example. Specifically, the power supply unit 111 supplies electric power to the vibration generating unit 41, the driving unit 45, the reading device 130, and the like of the supply unit 80. Further, the power supply unit 111 may be connected to an external power supply. The power supply unit 111 may supply electric power to each functional unit under the control of the first control device 50a, but the power supply unit 111 is not limited to this.

As a result, it is possible to prevent other parts from being mixed into the case 10. The cover 17 has, for example, a plate shape.

A through hole 17a is formed in the cover 17. The through hole 17a penetrates the cover 17 in the X-axis direction (longitudinal direction of the feeder 20). The through hole 17a may be provided at a position corresponding to the rod body 33 of the mounted portion 32 of the attachment 30, and may be of a size that allows the rod body 33 to be inserted. The through hole 17a may be, for example, of a size that does not allow a worker's finger to enter. Further, a sticker may be attached at a position corresponding to the through hole 17a of the cover 11. By inserting the rod 33 into the through hole 17a of the cover 11, the seal is in a state of having a hole. That is, the seal is provided so that it can be discerned whether the case 10 has been used or not.

FIG. 6B is an enlarged view showing the broken line region R of FIG. 5, and shows a state (open state) in which the case 10 is mounted on the mounted portion 32 and the cover 11 of the case 10 is open. .. For example, when the case 10 is attached to the attachment 30 and the collation is successful, the cover 11 is opened as shown in FIG. 6B.

When the case 10 is attached to the attachment 30 and the collation is successful, the first control device 50a controls the drive unit 45 to move the rod body 33 to the case 10 side. As a result, the rod body 33 inserts the through hole 17a of the cover 17 and pushes the one end portion 11a of the cover 11 toward the minus side of the X-axis. As a result, in the example of FIG. 6, the cover 11 rotates counterclockwise about the axis of rotation J. In other words, the rod body 33 presses the cover 11 to rotate the cover 11 about the rotation axis J.

As described above, the cover 11 is changed from the closed state to the open state by the physical action of the rod body 33 of the attached portion 32 to which the case 10 is attached / detached.

The transition from the open state to the closed state of the cover 11 may be realized by moving the rod body 33 to the X-axis plus side (the rod body 33 is housed inside the mounted portion 32). In this case, the cover 11 can be closed only by the first control device 50a controlling the drive unit 45 to move the rod body 33 to the X-axis plus side. When the cover 11 can be closed, the drive unit 45 automatically shifts the cover 11 from the open state to the closed state, so that workability is improved.

The cover 11 may be urged to be closed by an elastic body such as a spring (not shown). For example, the other end of the cover 11 opposite to the one end 11a is pushed to the minus side of the X-axis by an elastic body, and the cover 11 rotates clockwise (when viewed from the direction of FIG. 6) about the rotation axis J. It is being urged in the direction of When the rod body 33 moves to the plus side of the X-axis (is housed inside the mounted portion 32), the cover 11 changes from the open state to the closed state, and the cover 11 is urged to the minus side of the X-axis. As a result, it is possible to prevent the cover 11 from opening and closing due to shaking when the case 10 is being conveyed by the transfer robot 60.

Note that the open state of the cover 11 may be provided with a plurality of stages. That is, a plurality of opening degrees of the opening 15 may be provided. For example, the open state stage of the cover 11 is controlled by the first control device 50a according to the supply amount of parts and the like. FIG. 7 is a second diagram for explaining the opening and closing of the cover 11 of the case 10 according to the present embodiment. FIG. 7 is a diagram partially showing an example of a cross section taken along line VII-VII in FIG. 6 (b). In FIG. 7, the rod body 33 is not shown.

As shown in FIG. 7, the case main body 12 has a plurality of locking portions 12b protruding from the inner surface of the case main body 12 and the cover 17 at a portion surrounding one end portion 11a. FIG. 7 illustrates an example of having five locking portions 12b1 to 12b5, but the number of locking portions 12b is not particularly limited. In FIG. 7, one end 11a of the cover 11 is fixed by the locking portions 12b4 and 12b5. When the cover 11 is in the closed state, one end portion 11a of the cover 11 may be fixed by the locking portion 12b1 and the inner surface (the surface on the minus side of the X-axis) of the cover 17. As a result, it is possible to prevent the cover 11 from opening and closing due to shaking when the case 10 is being conveyed by the transfer robot 60.

When the cover 11 is opened, the elastic body provided to urge the cover 11 to be closed is locked. For example, the movement of the elastic body to the negative side of the X-axis is restricted so that the other end of the cover 11 opposite to the one end 11a is not urged to the negative side of the X-axis by the elastic body. As a result, the cover 11 can maintain a desired open state even if it is not continuously pressed by the rod body 33 by providing the locking portion 12b. The first control device 50a may open the cover 11 to a desired degree of opening by the rod body 33, and then return the rod body 33 to the mounted portion 32. As a result, the power consumption required for the rod body 33 to continue pressing the one end portion 11a can be reduced. In addition, deterioration of the rod body 33 can be suppressed.

When the case 10 is removed from the attachment 30, the elastic body is unlocked and the cover 11 is urged to be closed. The mechanism for closing the cover 11 is not limited to this. A rod body (not shown) that pushes one end of the cover 11 opposite to the one end 11a in the minus direction of the X-axis may be provided.

Further, when the locking portion 12b is provided, the cover 11 does not have to be urged to be closed by an elastic body such as a spring. That is, when the locking portion 12b is provided, the elastic body for closing the cover 11 may not be provided. In this case, the cover 11 may be locked by the locking portion 12b so that the opening degree of the opening 15 becomes smaller when the case 10 is removed from the attachment 30.

With reference to FIG. 5 again, the case main body portion 12 is an accommodating body for accommodating parts in a bulk state. The case body 12 is, for example, a long box body. The case main body 12 has a storage chamber 12a for accommodating parts in a bulk state. The accommodation chamber 12a has an inclined surface 16 that inclines downward toward the opening 15 (in the example of FIG. 5, in the negative direction of the Z axis). The inclination angle of the inclined surface 16 is not particularly limited, and it is sufficient that the parts of the accommodation chamber 12a move along the inclined surface 16 due to the vibration of the vibration generating portion 41 and can be supplied to the attachment 30.

Since the accommodation chamber 12a has the inclined surface 16, it becomes easy to supply parts to the attachment 30, and a space can be formed between the accommodation chamber 12a and the outer wall of the case main body portion 12. In the present embodiment, the RF tag T2 is arranged in the space. The RF tag T2 is arranged, for example, inside the case main body 12 and below the storage chamber 12a (for example, the Z-axis minus side of the case main body 12). Further, the RF tag T2 has a long shape and is arranged on the case main body 12 so that the longitudinal direction coincides with the longitudinal direction of the case main body 12. This makes it easier to attach the long RF tag T2 to the attachment surface 12c without increasing the area of the attachment surface 12c to which the RF tag T2 is attached.

The engaging portion 13 is a recess formed on the lower surface (the surface on the minus side of the Z axis) of the case main body portion 12 in order to fix the case 10 to the attachment 30. The engaging portion 13 is provided at a position corresponding to the claw portion 37 of the mounted portion 32 of the attachment 30, and engages with the claw portion 37. That is, the case 10 is fixed to the attachment 30 by engaging the engaging portion 13 and the claw portion 37.

From the viewpoint of suppressing the mixing of other parts into the case 10 and the attachment 30, it is preferable that the case 10 cannot be easily removed after the case 10 is attached to the attachment 30. For example, after the case 10 is attached to the attachment 30, the movement of the claw portion 37 (for example, the movement in the Z-axis direction) may be restricted by the drive portion 45. As a result, it is possible to prevent the parts from being mixed by the operator accidentally removing the case 10 from the attachment 30. For example, after the operator removes the case 10 from the attachment 30, it is possible to prevent the case 10 containing parts other than the parts corresponding to the attachment 30 from being attached to the attachment 30. It is possible to remove the attachment 30 from the case 10 by removing the regulation of the drive unit 45.

The first convex portion 14 is a portion gripped by the robot arm 61 when the transfer robot 60 attaches the case 10 to the attachment 30 of the supply unit 80. The first convex portion 14 is provided so as to project from the wall surface on the minus side of the X axis of the case main body portion 12 to the minus side of the X axis, for example. The first convex portion 14 has a positioning portion 14a that determines a gripping position when the robot arm 61 grips the first convex portion 14. The positioning portion 14a is, for example, a pair of recesses formed on the upper and lower surfaces of the first convex portion 14. FIG. 8 is a diagram schematically showing how the transfer robot 60 grips the case 10 according to the present embodiment. FIG. 8A is a diagram schematically showing the case 10 and the robot arm 61 when the Y-axis plus side is viewed from the Y-axis minus side, and FIG. 8B is a diagram schematically showing the case 10 and the robot arm 61 from the X-axis plus side. It is a figure which shows typically the case 10 and the robot arm 61 when the X-axis minus side is seen.

As shown in FIG. 8A, in the present embodiment, the positioning portion 14a, which is a recess, has a shape in which the cross-sectional area becomes smaller toward the inner part of a hole such as a quadrangular pyramid. Further, as shown in FIGS. 8A and 8B, in the present embodiment, the robot arm 61 has a fitting portion 61a to be fitted to the positioning portion 14a. The fitting portion 61a has a shape corresponding to the shape of the recess of the positioning portion 14a, and has, for example, a shape in contact with the side surface of the hole of the positioning portion 14a. As a result, when the transfer robot 60 tries to grip the case 10 with the robot arm 61, even if the positions of the positioning portion 14a and the fitting portion 61a do not completely match, the force gripped by the robot arm 61 causes the case 10. , The center of the fitting portion 61a and the center of the positioning portion 14a move so as to coincide with each other. Therefore, the transfer robot 60 can accurately grip the case 10. Further, the transfer robot 60 can prevent the case 10 from falling while the case 10 is being conveyed by providing the case 10 with the positioning portion 14a.

The position where the first convex portion 14 is provided is not limited to the position shown in FIG. 5 as long as the transfer robot 60 can grip the case 10. The first convex portion 14 may be provided, for example, so as to project from the wall surface (upper surface) on the Z-axis plus side of the case main body portion 12 toward the Z-axis plus side. Further, the positioning portion 14a is not limited to being a concave portion, and may be a convex portion or a portion having a friction coefficient different from that of other portions.

With reference to FIG. 5 again, the second convex portion 18 is a portion that engages with the guide portion (guide portion 39 shown in FIG. 9) provided in the attachment 30 when the case 10 is attached to the attachment 30. .. As shown in FIG. 9, the second convex portion 18 is provided so as to project from the lower surface of the case 10 to the negative side of the Z axis. The second convex portion 18 engages with the guide portion 39 of the attachment 30 of the feeder 20 in a state where the case 10 is attached to the attachment 30. As a result, the case 10 is fixedly attached to the attachment 30. The second convex portion 18 is formed, for example, by forming a long notch 19 in the longitudinal direction of the case 10 on the lower surface of the case main body portion 12. Further, the length in the longitudinal direction (length in the X-axis direction) of the case 10 in the second convex portion 18 is shorter than the length in the longitudinal direction of the case 10, but is not limited thereto. Further, the second convex portion 18 is arranged on the opening 15 side of the lower surface of the case 10. The second convex portion 18 may be provided at a position that does not overlap with the RF tag T2 in a plan view, for example. FIG. 9 is a schematic view of the feeder 20 to which the case 10 according to the present embodiment is attached when viewed from the longitudinal direction of the case 10. FIG. 9 is a diagram partially showing an example of a cross section taken along the line IX-IX in FIG.

As shown in FIG. 9, the second convex portion 18 engages with the guide portion 39 of the attachment 30 of the feeder 20. When the case 10 is attached to the attachment, the second convex portion 18 is attached along the guide portion 39, so that the workability when attaching the case 10 to the attachment 30 is improved.

Further, the width w1 of the second convex portion 18 is shorter than the width w2 of the case 10. Thereby, the width of w2 of the case 10 can be increased as compared with the case where the width w1 of the second convex portion 18 is the same as the width w2 of the case 10. For example, the width w2 of the case 10 can be made equal to the width of the attachment 30. Thereby, the accommodation capacity of the accommodation chamber 12a can be increased. Further, the width w1 of the second convex portion may be smaller than the width (length in the Y-axis direction) of the holding portion 71 of the carriage 70, which will be described later. At this time, for example, the width w2 of the case 10 may be the same as the width of the holding portion 71. As a result, the width of the opening 15 can be increased, so that clogging of parts at the opening 15 can be suppressed.

Further, the cross-sectional shape of the second convex portion 18 may be a rectangular shape or a T-shaped shape (T-shaped slot shape). Since the cross-sectional shape of the second convex portion 18 is T-shaped, the case 10 can be fixed in the vertical direction (Z-axis direction) as well. The cross-sectional shape of the second convex portion 18 is not limited to this, and may be, for example, a wedge shape (a wedge shape that tapers toward the minus side of the Z axis) or any other shape. good.

Further, the example in which the notch portion 19 is formed on both end sides (Y-axis plus side and Y-minus side) of the lower surface of the case 10 when viewed from the longitudinal direction of the case 10 has been described, but the present invention is limited to this. Instead, it may be formed only on one end side, or may be formed at a central position in the Y-axis direction.

The RF tag T2 stores information about the parts housed in the case 10 to which the RF tag T2 is attached. The RF tag T2 stores, for example, tag information such as information indicating the type of parts (identification information), information indicating the quantity (remaining number), and information indicating the expiration date. The RF tag T2 may be attached to the case 10 already when the case 10 is delivered from the component manufacturer, for example. As a result, by storing the delivered case 10 in the parts storage W, the mounting system 1 can acquire information about the parts of the case 10 via the reader / writer RW. Information such as a warehousing date and a control number may be written in the RF tag T2 by the reader / writer of the parts storage W. Further, the case 10 having no remaining amount may be transported to the disposal area after being processed so that the information stored in the RF tag T2 cannot be read. This makes it possible to prevent parts from being mixed due to reuse of the case 10. The RF tag T2 is an example of a second RF tag.

[1-2-2. attachment]
As shown in FIGS. 3 and 4, the feeder 20 has a case 10 detachably attached (for example, detachable), an attachment 30 for transporting parts, and a feeder main body 40 to which the attachment 30 is detachably attached. And have. It can be said that the feeder 20 includes a feeder main body 40 and an attachment 30 having an attached portion 32 that is removable from the feeder main body 40 and to which the case 10 is detachably attached. Further, it can be said that the feeder 20 can be separated into the attachment 30 and the feeder main body 40. For example, when the transport unit for transporting parts (corresponding to the transport portion 34 of the present embodiment) and the feeder main body portion (corresponding to the feeder main body portion 40 of the present embodiment) are integrated, it depends on the type of parts. The transport unit is shared. In this case, the parts used in the previous production may remain in the transport unit, and the parts of the case newly attached to the feeder (corresponding to the feeder 20 of the present embodiment) and the parts remaining in the transport unit. And may be mixed. Such a mixture tends to be a problem especially when the parts supplied by the feeder 20 are changed to different types of parts for production. On the other hand, in the feeder 20 according to the present embodiment, the attachment 30 having the transport portion 34 and the feeder main body portion 40 can be separated. Therefore, by providing the transport portion 34 (attachment 30) exclusively for the parts, the feeder 20 can be used. When supplying a plurality of different types of parts, it is possible to prevent the parts from being mixed. The feeder 20 can suppress mixing even when the size of the component is small. The feeder 20 has a long shape, and the longitudinal direction is the X-axis direction.

Further, as shown in FIGS. 3 and 4, the attachment 30 includes a mounted portion 32, a cover 32a, a rod body 33, a transport portion 34, a cover 35, a claw portion 37, and a convex portion 38. It has a guide unit 39 (see FIG. 9) and an RF tag T3. In the present embodiment, the mounted portion 32 and the transport portion 34 are integrally formed. Further, in the attachment 30, an opening 32b is formed at a position corresponding to the opening 15 of the case 10, and an opening 35a is formed at a position where a component is taken out by the mounting head 107.

The rod body 33 is an example of an acting unit that moves along the X-axis direction by a driving unit 45 provided in the feeder main body 40 and acts on the cover 11 provided in the opening 15 of the case 10.

The mounted portion 32 is a portion to which the case 10 is attached and detached, fixes the case 10, and opens and closes the cover 11 of the case 10. The mounted portion 32 is provided with a cover 32a, a rod body 33, a claw portion 37, and a guide portion 39.

The cover 32a covers the opening 32b to prevent other parts from being mixed into the attachment 30. The cover 32a is provided between the opening 15 and the transport portion 34. The cover 32a covers the opening 32b when the case 10 is not attached to the attachment 30. Further, the cover 32a is opened when the case 10 is attached to the attachment 30 and the case 10 is collated as to whether the case 10 is attached to the attachment 30 and the collation is successful. The cover 32a may be opened and closed by, for example, the drive unit 45. The cover 32a may be closed when the attachment 30 to which the case 10 is attached is removed from the feeder main body 40. As a result, it is possible to prevent the parts of the case 10 from invading the transport unit 34.

As described above, the mounted portion 32 has a cover 32a provided in the opening 32b formed at a position corresponding to the opening 15 of the case 10 in a state where the case 10 is mounted on the mounted portion 32. The cover 32a is an example of the second cover.

The rod body 33 is an example of an opening / closing mechanism for opening / closing the cover 11. In the present embodiment, the cover 11 is rotated around the rotation axis J by pressing the cover 11 to open / close the cover 11. For example, by pressing the cover 11, the parts of the case 10 can be supplied to the transport unit 34. The rod body 33 is arranged, for example, at a position where one end portion 11a of the cover 11 can be pressed. The shape of the rod 33 is not particularly limited. Further, when the rod body 33 does not press the one end portion 11a, it is preferable that the rod body 33 is housed inside the mounted portion 32. As a result, it is possible to prevent the rod body 33 from coming into contact with the one end portion 11a when the case 10 is attached to the attachment 30 or the like.

As described above, the attachment 30 according to the present embodiment has an opening / closing mechanism for opening / closing the cover 11 of the case 10.

The claw portion 37 is a convex portion provided at a position where the lower surface of the case 10 comes into contact with the mounted portion 32 in order to fix the case 10 to the attachment 30. The claw portion 37 engages with the engaging portion 13 of the case 10 to fix the case 10 to the attachment 30. Although the details will be described later, the claw portion 37 can be moved between the first position accommodated in the mounted portion 32 and the second position protruding from the mounted portion 32. That is, the claw portion 37 can move in the Z-axis direction. FIG. 4 shows an example in which the claw portion 37 is fixed at the second position. The movement of the claw portion 37 between the first position and the second position may be performed by, for example, the drive unit 45 or an elastic body such as a spring.

The shape of the claw portion 37 when viewed from the Y-axis direction is, for example, a triangle, and in FIG. 4, it is a right triangle. Even if the claw portion 37 is formed, for example, when viewed from the Y-axis direction, the inclination increases toward the opening 32b side (in the example of FIG. 4, the hypotenuse of the right triangle rises to the right). good.

The guide portion 39 functions as a guide when the case 10 is fixedly attached to the attachment 30 and the case 10 is attached to the attachment 30 in a state where the case 10 is attached to the attachment 30. The guide portion 39 is configured to include a support portion 39a that supports both ends of the case 10 in the width direction, and a groove portion 39b between the support portions 39a. As shown in FIG. 9, when the support portion 39a supports the lower surface of the case 10, the second convex portion 18 projecting from the lower surface of the case 10 engages with the guide portion 39. The support portion 39a has a shape corresponding to the notch portion 19. The width w3 of the groove portion 39b is shorter than the width w2 of the case 10. The support portion 39a is provided so as to project from both ends of the mounted portion 32 toward the Z-axis plus side when viewed from the X-axis direction.

The transport unit 34 transports the parts supplied from the case 10 to the position where they are taken out by the mounting head 107. In the present embodiment, the transport unit 34 transports the parts by the vibration generated by the vibration generation unit 41. The transport unit 34 is an example of a component transport unit.

FIG. 10 is a diagram for explaining the transfer of the component P by the transfer unit 34 according to the present embodiment. FIG. 10 shows a state when the transport unit 34 is viewed from the Z-axis plus side.

As shown in FIG. 10, the transport unit 34 transports the component P so that the component P supplied from the case 10 is aligned toward the opening 35a. Specifically, the transport unit 34 has a guide portion 34a for aligning the parts P, and the parts P are transported along the guide portion 34a by the vibration from the vibration generating unit 41. Align P. Alignment here means that the parts P have the same orientation and are arranged in a row. The transport unit 34 does not have to align the parts P as long as it can be taken out by the mounting head 107 even if the parts P are not aligned. For example, the transport unit 34 does not have to have the guide unit 34a.

With reference to FIGS. 3 and 4, the cover 35 covers the opening 35a. The cover 35 is opened when the component is taken out by the mounting head 107. The cover 35 is opened after the covers 11 and 32a are opened. The opening and closing of the cover 35 may be performed by, for example, the drive unit 45.

FIG. 11A is a diagram showing a state in which the cover 35 of the attachment 30 according to the present embodiment is open. FIG. 11B is a diagram showing a state in which the cover 35 of the attachment 30 according to the present embodiment is closed. FIG. 11C is a diagram showing a state in which the cover 35 of the attachment 30 according to the present embodiment is closed and locked.

As shown in FIG. 11A, the cover 35 slides in the plus direction of the X-axis to open the cover 35. That is, the parts are exposed from the opening 35a. In this state, the mounting head 107 takes out the parts conveyed to the position of the opening 35a.

The surface of the attachment 30 on the plus side of the Y-axis is formed with a first portion 30a, a second portion 30b, and a third portion 30c having different thicknesses in the minus direction of the Y-axis. The first portion 30a is a surface that comes into contact with the inner surface of the cover 35 when the cover 35 slides. The second portion 30b is a portion thicker than the first portion 30a. The third portion 30c is a portion thicker than the second portion 30b. For example, the first portion 30a, the second portion 30b, and the third portion 30c are formed in a staircase pattern. The first portion 30a, the second portion 30b, and the third portion 30c may be formed on at least one of the Y-axis plus side surface and the Y-axis minus side surface of the attachment 30.

As shown in FIG. 11B, the opening 35a is closed by sliding the cover 35 in the minus direction of the X-axis. That is, the cover 35 changes from the open state to the closed state. At this time, the contact portion 35b of the cover 35 comes into contact with the second portion 30b, so that the movement in the minus direction of the X axis is restricted. The cover 35 is formed so as to cover the opening 35a in a state where the contact portion 35b is in contact with the second portion 30b. At this time, the cover 35 is in a movable state in the plus direction of the X hour axis. That is, the state in which the contact portion 35b is in contact with the second portion 30b is a state in which the cover 35 can be easily opened. It can be said that the cover 35 is in a state of functioning as a shutter so that the parts in the transport portion 34 do not pop out. For example, when the cover 35 needs to be opened and closed frequently, the states shown in FIGS. 11A and 11B are repeated. For example, while the mounting head 107 does not take out the component, the state transitions from the open state to the state shown in FIG. 11B.

As shown in FIG. 11C, the cover 35 further slides (pushes in) in the minus direction of the X-axis from the state shown in FIG. 11B, so that the contact portion 35b comes into contact with the third portion 30c. At this time, since the cover 35 and the second portion 30b are in contact with each other, the cover 35 cannot be easily moved. That is, the cover 35 cannot be easily opened. It can be said that the cover 35 functions as a lid for covering the opening 35a. For example, when the attachment 30 is removed from the feeder main body 40, the state transitions to the state shown in FIG. 11C. The transition of the state of the cover 35 shown in FIGS. 11A to 11C is executed by the first control device 50a.

With reference to FIGS. 3 and 4 again, the engaging portion 36 is a recess formed in the lower surface (Z-axis minus side surface) of the attachment 30 for fixing the attachment 30 to the feeder main body 40. be. The engaging portion 36 is provided at a position corresponding to the claw portion 43 provided in the feeder main body portion 40, and engages with the claw portion 43. That is, the attachment 30 is fixed to the feeder main body 40 by engaging the engaging portion 36 and the claw portion 43.

The convex portion 38 is a portion gripped by the robot arm 61 when the transfer robot 60 attaches the attachment 30 to the feeder main body portion 40 of the supply unit 80.

Further, when there is a remaining number of parts in the case 10 (Yes in S103), the first control device 50a returns to step S101 and continues to supply the parts. That is, the first control device 50a maintains the open state of the cover 11 of the case 10 and the cover 32a of the attachment 30 based on the remaining number acquired in step S102. It can be said that the first control device 50a maintains the state in which the cover 11 is opened when there are remaining parts in the case 10.

The first control device 50a determines in step S103 based on, for example, the remaining number of parts in the attachment 30 (for example, in the transport unit 34) or the detection result indicating that the parts remain in the attachment 30. You may go. In this case, when the first control device 50a acquires the information indicating that there are a predetermined number or more of parts in the attachment 30 or the parts remain in the attachment 30, it is determined as Yes in step S103. The information may be, for example, the detection result of the sensor 140. The sensor 140 may be arranged in the middle of the transport unit 34, for example. For example, the sensor 140 may be provided in the transport unit 34 so as to be able to detect whether or not there is a supply of parts from the upstream side (case 10 side) of the transport unit 34.

The above steps S101 to S103 may be executed as part of the mounting process.

Next, in order to replace the case 10, the first control device 50a changes the cover 11 of the case 10 and the cover 32a of the attachment 30 from the open state to the closed state (S104). That is, the first control device 50a changes the cover 11 of the case 10 and the cover 32a of the attachment 30 from the open state to the closed state based on the remaining number acquired in step S102. It can be said that the first control device 50a closes the cover 11 when there are no remaining parts in the case 10.

At the time of step S104, parts still remain in the transport unit 34 of the attachment 30. Therefore, the steps after step S104 can be executed in parallel with the mounting step. That is, the case 10 can be replaced while holding the parts in the transport unit 34 and mounting them on the substrate 103.

The case 10 with no remaining number is transported to the disposal area by the transfer robot 60. Therefore, in step S104, the cover 11 of the case 10 does not have to be closed. That is, in step S104, the cover 32a of the attachment 30 may be closed. In this case, the opening 32b of the mounted portion 32 in the state where the case 10 is removed from the mounted portion 32 of the feeder 20 is closed by the cover 32a.

Further, the second control device 50b causes the transfer robot 60 to replace the case 10 by outputting a supply instruction (S105). The transfer robot 60 conveys the case 10 containing the parts having no remaining number from the storage area A1 or the preparation area A2 to the position of the case 10 having no remaining number, and replaces the case 10. The replenishment instruction may include information for specifying the case 10 to be transported from the storage area A1 or the preparation area A2, and information for specifying the position for exchanging the case 10 (for example, the position of the feeder 20). ..

Here, the operation of the transfer robot 60 to attach the case 10 to the attachment 30 will be described with reference to FIG. FIG. 14 is a diagram showing how the case 10 is attached to the attachment 30 according to the present embodiment. The case 10 shown in FIG. 14 is moved by the transfer robot 60, but the transfer robot 60 is not shown. In FIG. 14, only the engaging portion 13 and the claw portion 37 are hidden by a broken line.

FIG. 14A shows a state in which a part of the case 10 is placed on the mounted portion 32 of the attachment 30. At this time, the claw portion 37 is in a second position protruding from the mounted portion 32.

FIG. 14B shows a state in which the case 10 is moved to the position of the claw portion 37 by the transfer robot 60. At this time, the claw portion 37 is pushed by, for example, the case 10 and moves to the inside of the mounted portion 32. That is, the claw portion 37 moves to the first position accommodated in the mounted portion 32. The movement of the claw portion 37 may be performed by the drive portion 45. Further, as for the claw portion 37, at least a part of the claw portion 37 may be accommodated in the mounted portion 32. The position of the claw portion 37 in which at least a part thereof is housed in the mounted portion 32 is also included in the first position.

FIG. 14C shows a state in which the engaging portion 13 of the case 10 and the claw portion 37 are engaged and the case 10 is fixed to the attachment 30. At this time, the claw portion 37 is in the second position. In this state, the tag information of the RF tag T2 of the exchanged case 10 has not been collated. Therefore, it is preferable that the cover 11 of the case 10 and the cover 32a of the mounted portion 32 remain in the closed state. Not limited to this. As long as the case 10 is fixed to the attachment 30, the cover 32a of the mounted portion 32 may be in the open state.

As described above, the claw portion 37 is movable between the first position in which at least a part thereof is accommodated in the mounted portion 32 and the second position protruding from the mounted portion 32. Then, the claw portion 37 engages with the engaging portion 13 provided on the lower surface of the case 10 at the second position to fix the case 10 to the mounted portion 32. The first position may be a position on the minus side of the Z axis from the second position.

With reference to FIG. 13 again, the first control device 50a then controls the reading device 130 to read the tag information of the replaced RF tag T2 of the case 10 (S106). The first control device 50a controls the switching unit 132 to conduct the reading unit 131 and the antenna a2. The reading unit 131 reads the tag information from the RF tag T2 via the antenna a2, and outputs the read tag information to the integrated control device 50 via the first control device 50a. As a result, the integrated control device 50 can acquire the tag information of the RF tag T2 of the exchanged case 10.

Next, the integrated control device 50 determines whether or not the replaced case is appropriate (S107). The integrated control device 50 may determine, for example, whether or not the tag information acquired in step S106 matches the production data. The integrated control device 50 may determine, for example, whether or not the type of the component included in the tag information and the type of the component corresponding to the feeder 20 included in the production data match. Further, the integrated control device 50 may determine whether the number of parts included in the tag information is equal to or larger than the number of parts required for production included in the production data. Matching in this case includes the quantity of parts satisfying the production data.

Note that in step S107, the determination may be made without using the production data. For example, the integrated control device 50 may make a determination in step S107 depending on whether or not the types of parts of the case 10 before and after replacement match. Further, the integrated control device 50 may make a determination in step S107 depending on whether or not the component type of the attachment 30 matches, in addition to the determination using the type of component included in the production data.

The integrated control device 50 proceeds to step S108 when the replaced case 10 is appropriate (Yes in S107). Further, when the replaced case 10 is not appropriate (No in S107), the integrated control device 50 returns to step S105 and causes the case to be replaced again. It should be noted that the determination of Yes in step S107 is an example of successful collation, and the determination of No in step S107 is an example of failure of collation.

Next, when the integrated control device 50 determines Yes in step S107, the first control device 50a changes the cover 11 of the case 10 and the cover 32a of the attachment 30 from the closed state to the open state (S108). That is, the first control device 50a changes the cover 11 of the case 10 and the cover 32a of the attachment 30 from the closed state to the open state based on the determination result of step S107.

FIG. 14D shows a state in which the cover 11 of the case 10 and the cover 32a of the attachment 30 are changed from the closed state to the open state. As described above, the first control device 50a collates the tag information of the exchanged case 10 with the production data, and when the collation is successful, for example, when the tag information and the production data match, the covers 11 and 32a Is opened, and the supply of parts to the attachment 30 is started.

By replacing the case 10 in this way, it is possible to replace the case 10 without stopping the mounting process and suppressing the mixing of parts. The above steps S104 to S108 are examples of parts replenishment steps. The parts supply step is executed with the parts remaining in the transport unit 34.

Subsequently, the operation when the dolly 70 attached to the component mounting device 100 is replaced will be described with reference to FIGS. 15 to 17. FIG. 15 is a flowchart showing an operation of exchanging the case 10 and the feeder 20 of the mounting system 1 according to the present embodiment. Specifically, FIG. 15 shows an operation of preparing a dolly 70 for replacement in the preparation area A2 in advance. FIG. 16 is a flowchart showing an operation of acquiring the tag information shown in FIG. FIG. 16 describes an example in which the RF tag is an RF tag for a long distance. The RF tag for a long distance is, for example, an RF tag capable of communication with a communication distance of about 1 to 2 m. The RF tag may be an RF tag for a short distance. The RF tag for a short distance has a shorter communication distance than the RF tag for a long distance, for example, about several tens of centimeters. Further, FIG. 16 describes an operation of specifying the RF tag corresponding to the antenna a1 by using the radio wave strength of the signal among the radio wave strength of the signal and the number of times the signal is detected.

As shown in FIG. 15, the second control device 50b attaches the case 10 and the attachment 30 to the trolley 70 arranged in the preparation area A2 (S201). The second control device 50b controls the transfer robot 60 to hold a case 10 for accommodating parts used in the next production and an attachment 30 corresponding to the case 10, based on, for example, production data. It is attached to the feeder main body 40. It is assumed that the feeder main body 40 is preliminarily attached to the feeder slot of the carriage 70.

It is assumed that a plurality of feeder main bodies 40 are attached to the carriage 70, and in step S201, a case 10 and an attachment 30 corresponding to the case 10 are attached to each of the plurality of feeder main bodies 40. The antenna is arranged in each of the plurality of feeder main body portions 40.

Next, the first control device 50a acquires the tag information stored in the RF tags T2 and T3 from each of the plurality of RF tags T2 and T3 (S202). Since the RF tags T2 and T3 are RF tags for long distances, the first control device 50a simultaneously acquires signals from each of the plurality of RF tags T2 and T3. Therefore, the first control device 50a cannot specify the RF tags T2 and T3 corresponding to the antenna a1 from the acquired tag information. Therefore, in the present embodiment, the first control device 50a corresponds to the antenna a1 based on at least one of the radio wave intensity of the signal received from each of the plurality of RF tags T2 and T3 and the number of times the signal is detected. The RF tags T2 and T3 to be used are specified. In step S202, for example, at least one of the RF tags T2 and T3 may be acquired. Hereinafter, the case where the first control device 50a specifies the RF tag T2 will be described, but the case where the RF tag T3 is specified may be specified in the same manner. In step S202, the control unit 51 of the integrated control device 50 may acquire the tag information stored in the RF tags T2 and T3 from each of the plurality of RF tags T2 and T3. That is, the tag information may be acquired by the first control device 50a or the control unit 51.

Further, the first control device 50a may specify the RF tag T1 corresponding to the antenna a1 based on at least one of the radio wave intensity of the signal received from the plurality of RF tags T1 and the number of times the signal is detected. ..

As shown in FIG. 16, the first control device 50a acquires the radio wave intensity of the signal from each of the plurality of RF tags T2 (S301). The first control device 50a calculates the radio wave strength (signal strength) of the signal based on the signal acquired from the RF tag T2.

Next, the first control device 50a identifies the RF tag T2 corresponding to the antenna a1 based on the plurality of radio wave intensities (S302). Specifically, the first control device 50a determines that the RF tag T2 corresponding to the signal having the strongest radio field strength among the plurality of radio wave strengths is the RF tag T2 corresponding to the antenna a1. FIG. 17 is a schematic diagram for explaining a process of specifying the RF tag T2 corresponding to the antenna a1. The width of the double-headed arrow shown in FIG. 17 indicates the strength of the signal transmitted from each RF tag T2 to the antenna a1 arranged on the leftmost side. The larger the width, the higher the signal strength.

As shown in FIG. 17, the radio field intensity changes depending on the distance and / or angle between the antenna a1 and the RF tag T2. Therefore, by specifying the RF tag T2 based on the radio wave strength, the antenna a1 The RF tag T2 corresponding to the above can be specified accurately. In the example of FIG. 17, it can be seen that the RF tag T2 corresponding to the antenna a1 on the Y-axis plus side is the RF tag T2 on the Y-axis plus side.

The first control device 50a acquires signals from each of the plurality of RF tags T2. The first control device 50a calculates the number of times a signal is detected from each of the plurality of RF tags T2. The first control device 50a identifies the RF tag T2 corresponding to the antenna a1 based on the number of times a signal is detected for each RF tag T2. Specifically, the first control device 50a determines that the RF tag T2 having the largest number of signal detections is the RF tag T2 corresponding to the antenna a1. Since the number of signal detections varies depending on the distance and / or angle between the antenna a1 and the RF tag T2, the RF corresponding to the antenna a1 can be specified by specifying the RF tag T2 based on the number of signal detections. The tag T2 can be specified accurately.

In order to ensure isolation, the side surfaces (Y-axis side surfaces) of each feeder 20 may be formed of metal.

With reference to FIG. 16 again, the first control device 50a then determines whether or not the RF tag T2 has been specified for all the antennas a1 (S303). When the RF tag T2 is specified for all the antennas a1 (Yes in S303), the first control device 50a proceeds to S203 shown in FIG. Further, when the RF tag T2 is not specified for all the antennas a1 (No in S303), the first control device 50a returns to step S301 and continues the processing after step S301 for the remaining antennas a1. .. Specifically, the first control device 50a controls the switching unit 132 to switch the antenna a1 connected to the reading unit 131, and performs the processing after step S301 on the switched antenna a1. The first control device 50a outputs the acquired tag information to the integrated control device 50.

The processing of steps S301 to S303 may be performed by the reading device 130. The reading device 130 may have some functions of the first control device 50a.

With reference to FIG. 15 again, the integrated control device 50 then determines whether or not the case 10 and the attachment 30 attached to the feeder main body 40 are appropriate based on the tag information (S203). The integrated control device 50 may make a determination in step S203, for example, by collating the tag information with the production data. In the integrated control device 50, for example, the types of parts included in the tag information of the case 10 and the attachment 30 attached to the feeder main body 40 and the types of parts attached to the feeder main body 40 included in the production data are different. If they match, the mounting positions of the case 10 and the attachment 30 are appropriate (the case 10 and the attachment 30 are attached to the appropriate feeder main body 40), so that the case 10 and the attachment 30 are determined to be appropriate. (Yes in S203). Further, the integrated control device 50 is, for example, a type of parts included in the tag information of the case 10 and the attachment 30 attached to the feeder main body 40, and a type of parts attached to the feeder main body 40 included in the production data. If does not match, it is determined that the mounting positions of the case 10 and the attachment 30 are not appropriate (No in S203). The integrated control device 50 makes a determination in step S203 in each of the feeder main body portions 40. It should be noted that the determination as to whether or not the attachment position of the attachment is appropriate may be performed without using the production data. The integrated control device 50 may make a determination in step S203 depending on whether or not the component types of the tag information of the attachment 30 and the tag information of the case 10 match, for example. In addition, when determining whether or not the attachment position of the attachment is appropriate, the production data may be used in the same manner.

Next, when the integrated control device 50 determines Yes in step S203, the first control device 50a opens the cover 32a on the case 10 side of the attachment 30 attached to the carriage 70 of the component mounting device 100 from the open state to the closed state. (S204). At this time, the first control device 50a may also change the cover 11 of the case 10 from the open state to the closed state.

Next, the second control device 50b removes the trolley 70 of the component mounting device 100, and the trolley 70 determined to be Yes in step S203 in each of the feeder main body 40 (the trolley 70 in which the case 10 and the attachment 30 are appropriate). Is attached to the component mounting device 100 (S205). The first control device 50a changes the cover 32a on the case side of the attachment 30 of the newly attached trolley 70 from the closed state to the open state (S206). At this time, in the first control device 50a, the cover 11 of the case 10 may also be changed from the closed state to the open state.

By replacing the dolly 70 to which the case 10 and the feeder 20 are attached in this way, it is possible to quickly replace the dolly 70 while suppressing the mixing of parts. The above steps S201 to S206 are examples of the parts replenishment process.

[1-4. Effect etc.]
As described above, the mounting system 1 according to the present embodiment includes a feeder 20 in which a case for accommodating bulk parts is detachable, a trolley 70 in which the feeder 20 is arranged, and parts supplied by the feeder 20. The information contained in the mounting head 107 that is held and mounted on the object, the RF tag T1 provided on the feeder 20, and the RF tag T2 provided on the case 10 can be read, and the reading device 130 provided on the trolley 70 can be read. And may be provided.

The dolly 70 is an example of a feeder arrangement portion, the RF tag T1 is an example of a first RF tag, and the RF tag T2 is an example of a second RF tag.

Thereby, the reading device 130 can acquire information (tag information) from each of the two RF tags. For example, by reading the barcode, it is possible to reduce the time and effort required to acquire the tag information. Therefore, workability when acquiring tag information is improved.

Further, the reading device 130 has an antenna a1 capable of transmitting and receiving a signal to the RF tag T1 and an antenna a2 capable of transmitting and receiving a signal to the RF tag T2. It can be said that the reading device 130 has an antenna a1 configured to detect the RF tag tT1 and an antenna a2 configured to detect the RF tag T2.

Note that the antenna a1 is an example of the first antenna, and the antenna a2 is an example of the second antenna.

As a result, since an antenna is provided for each of the two RF tags, tag information can be efficiently acquired from each RF tag as compared with the case where the antenna is shared.

Further, the mounting system 1 may further include a transmission unit capable of transmitting a signal from the antenna a2 to the RF tag T2 provided in the case 10.

As a result, the antenna a2 can transmit and receive a signal via the transmission unit even when the signal cannot be directly transmitted and received to the RF tag T2.

Further, the transmission unit of the mounting system 1 includes an antenna a3 provided on the feeder 20 and arranged so as to face the RF tag T2, and an antenna a4 provided on the feeder 20 and arranged so as to face the antenna a2. , A cable C3 connecting the antenna a3 and the antenna a4. The transmission unit includes an antenna a3 arranged so as to face the RF tag T2, an antenna a4 provided so as to face the antenna a2 and configured to be directly detected by the reading device 130, and the antenna a3 and the antenna. It can be said that it has a cable C3 for connecting to a4.

Note that the antenna a3 is an example of the third antenna, the antenna a4 is an example of the fourth antenna, and the transmission unit is an example of the first transmission unit.

As a result, the antenna a2 can transmit and receive signals via the antenna a4, the cable C3, and the antenna a3 even when the signal cannot be directly transmitted and received to the RF tag T2. Further, since the antenna a3 and the antenna a4 are connected by the cable C3, the degree of freedom in the position where the antenna a3 and the antenna a4 are arranged is increased.

Further, the dolly 70 is configured so that a plurality of feeders 20 can be arranged. The reading device 130 has an antenna a1 in each of the plurality of feeders 20, and at least one of the strength of the signal received from the RF tag T1 of each of the plurality of feeders 20 and the number of times the signal is detected in each of the plurality of antennas a1. The RF tag T1 corresponding to the antenna a1 is determined based on the above. The reading device 130 is based on at least one of the strength of the signal received from the plurality of feeders 20 including the feeder 20 of 1 provided with the RF tag T1 to be read by the antenna a1 and the number of times the signal is detected. It can also be said that the RF tag T1 which is the reading target of a1 is determined. It can also be said that the number of times a signal is detected is the frequency of signal detection. The signal detection frequency indicates the number of times the signal is detected when the reading device 130 performs the detection operation for a certain period of time.

Thereby, the reading device 130 can easily and accurately determine the corresponding RF tag T1 by using at least one of the signal strength and the number of detections.

Further, the dolly 70 is configured so that a plurality of cases 10 can be arranged. For example, a plurality of cases 10 are arranged on the carriage 70 via the feeder 20. The reading device 130 reads the RF tag T2, which is the reading target, based on at least one of the strength of the signal received from the plurality of cases 10 including the case 10 provided with the RF tag T2 to be read and the number of times the signal is detected. To judge.

Thereby, the reading device 130 can easily and accurately determine the corresponding RF tag T2 by using at least one of the signal strength and the number of detections.

Further, the dolly 70 is configured so that a plurality of attachments 30 can be arranged. For example, a plurality of attachments 30 are arranged on the carriage 70 via the feeder main body 40. The reading device 130 reads the RF tag T3 to be read based on at least one of the strength of the signal received from the plurality of attachments 30 including the attachment 30 provided with the RF tag T3 to be read and the number of times the signal is detected. To judge.

Thereby, the reading device 130 can easily and accurately determine the corresponding RF tag T3 by using at least one of the signal strength and the number of detections.

Further, the feeder 20 may have a feeder main body 40 and an attachment 30 having an attached portion 32 that is detachable to and detachable from the feeder main body 40 and to which the case 10 is detachably attached.

Thereby, the feeder 20 can be separated into the feeder main body 40 and the attachment 30. For example, by setting the attachment 30 for each component, it is possible to prevent the components from being mixed in the attachment 30.

Further, the RF tag T1 is provided in the feeder main body 40, and the reading device 130 has an antenna a4 capable of transmitting and receiving signals to the RF tag T3 provided in the attachment 30.

The RF tag T3 is an example of a third RF tag, and the antenna a5 is an example of a fifth antenna.

Thereby, the reading device 130 can more reliably acquire the tag information of the RF tag T3 provided on the attachment 30 via the antenna a5.

Further, the antenna a3 transmits a signal including the information stored in the RF tag T2 to the RF tag T3. It can be said that the antenna a3 transmits the information detected from the RF tag T2 to the RF tag T3.

As a result, tag information can be aggregated in the RF tag T3. That is, it is possible to save the trouble required for reading the tag information. Therefore, it is possible to suppress a decrease in workability.

Further, the feeder 20 has a long shape, and the RF tag T2 and the RF tag T3 may be arranged so that at least a part thereof does not overlap in the longitudinal direction of the feeder 20.

This increases the certainty that the tag information can be read from each of the RF tags T2 and T3.

Further, the trolley 70 has a waiting area A21 in which a feeder, a case or a tape feeder provided with the RF tag T4 stands by. The reading device 130 has an antenna a6 capable of transmitting and receiving signals to and from the RF tag T4.

The RF tag T4 is an example of a fourth RF tag, and the antenna a6 is an example of a sixth antenna.

As a result, when there is an object stored in the standby area A21 of the trolley 70, tag information (for example, identification information, remaining number information, identification code of the tag itself, etc.) related to the object can be acquired.

Further, as described above, the feeder 20 according to the present embodiment includes a mounted portion 32 to which a case 10 for accommodating bulk parts is detachably attached. The mounted portion 32 has a rod body 33 that acts on the cover 11 provided in the opening 15 of the case 10. The rod body 33 physically acts on the cover 11 in a state where the case 10 is mounted on the mounted portion 32, so that the cover 11 is opened from the closed state.

The case 10 is an example of the housing, the opening 15 is an example of the first opening, the cover 11 is an example of the first cover, and the rod 33 is an example of the working part.

As a result, a rod body 33 for opening and closing the cover 11 is provided on the mounted portion 32 included in the feeder 20. Therefore, with the case 10 mounted on the mounted portion 32, the cover 11 can be opened by a physical action (for example, pressing) by the rod body 33. That is, the feeder 20 can open and close the cover 11 without driving the shutter opening / closing plate by the shutter opening / closing lever as in Patent Document 1. Therefore, according to the feeder 20 according to the present embodiment, it is possible to suppress a decrease in workability when opening and closing the cover 11.

Further, the mounted portion 32 has a guide portion 39 that engages with a second convex portion 18 that is provided so as to project from the lower surface of the case 10. The guide portion 39 has a support portion 39a that supports both ends of the case 10 in the width direction and a groove portion 39b provided between the support portions 39a, and the length (width w3) of the groove portion 39b in the width direction is set. It is shorter than the length of the case 10 in the width direction (width w2).

The second convex portion 18 is an example of the convex portion.

As a result, the width w2 of the case 10 can be widened as compared with the case where the second convex portion 18 is formed on the side surface of the case 10 (for example, the surface in the Y-axis direction), so that the component in the case 10 can be widened. Can be increased in capacity. Therefore, in the mounting process, the frequency of replacement of the case 10 can be reduced, and the productivity is improved.

Further, the mounted portion 32 has a claw portion 37 that can be moved between a first position housed in the mounted portion 32 and a second position protruding from the mounted portion 32. At the second position, the claw portion 37 engages with the engaging portion 13 provided on the lower surface of the case 10 to fix the case 10 to the mounted portion 32.

Thereby, the case 10 can be fixed to the mounted portion 32 by a simple fixing method such as engaging the claw portion 37 of the mounted portion 32 with the engaging portion 13 of the case 10. Further, since the claw portion 37 can move between the first position and the second position, the case 10 can be easily fixed to the mounted portion 32. Therefore, workability when fixing the case 10 to the mounted portion 32 is improved.

Further, the cover 11 is rotatably supported about the rotation axis J with respect to the case 10. By pressing the cover 11, the rod body 33 rotates the cover 11 about the rotation axis J.

As a result, the rod body 33 can open the cover 11 simply by pressing the cover 11. Therefore, workability when the cover 11 is opened is improved.

Further, the feeder 20 further includes a transport unit 34 for transporting the parts supplied from the case 10, and a feeder main body portion 40 to which the mounted portion 32 and the transport portion 34 are detachably attached.

The transport unit 34 is an example of a parts transport unit.

Thereby, the mounted portion 32 and the transport portion 34 can be provided for each part accommodated in the case 10. Therefore, it is possible to suppress the mixing of parts in the transport unit 34 as compared with the case where the transport unit 34 is shared regardless of the parts.

Further, the feeder 20 has a cover 32a provided in the opening 32b formed at a position corresponding to the opening 15 of the case 10 in a state where the case 10 is mounted on the mounted portion 32.

The opening 32b is an example of the second opening, and the cover 32a is an example of the second cover.

Thereby, for example, when the case 10 mounted on the mounted portion 32 is replaced, the opening 32b can be closed by the cover 32a. As a result, it is possible to prevent parts from being mixed in the transport unit 34 when the case 10 is replaced.

Further, as described above, the case 10 according to the present embodiment is a case attached to the feeder 20 described above, and the storage chamber 12a for accommodating the parts in a bulk state and the parts from the accommodation chamber 12a to the feeder 20. It is provided with a cover 11 provided in the opening 15 for supplying. The cover 11 is changed from the closed state to the open state by the physical action of the rod body 33 of the mounted portion 32 to which the case 10 is attached / detached.

This has the same effect as the feeder 20 described above. That is, according to the case 10, it is possible to suppress a decrease in workability when opening and closing the cover 11.

Further, a first convex portion 14 provided on the wall surface of the case 10 is further provided. The first convex portion 14 has a positioning portion 14a that determines a gripping position when gripping the first convex portion 14.

The first convex portion 14 is an example of the convex portion.

As a result, when the case 10 is conveyed by the transfer robot 60 or the like, the certainty that the robot arm 61 of the transfer robot 60 can appropriately grip the case 10 is increased.

Further, the accommodation chamber 12a has an inclined surface 16 that inclines downward toward the opening 15.

This makes it easier for parts to be supplied from the case 10 to the transport unit 34.

Further, as described above, the mounting system 1 according to the present embodiment includes the feeder 20, the board transport mechanism 102 that transports the substrate 103, and the mounting head 107 that takes out components from the feeder 20 and mounts them on the substrate 103. May be provided.

The board transfer mechanism 102 is an example of a board transfer section, the mounting head 107 is an example of a component mounting section, and the board 103 is an example of an object.

As a result, it is possible to realize the mounting system 1 in which the deterioration of workability in opening and closing the cover 11 is suppressed.

Further, as described above, in the mounting method according to the present embodiment, the case 10 for accommodating the bulk state parts is removable, and the feeder 20 having the attachment 30 for accommodating the parts supplied from the case 10 is used. This is a mounting method in the mounting system 1 including a mounting head 107 that holds the components supplied by the feeder 20 and mounts them on the substrate 103. The mounting method includes a mounting process in which the components in the feeder 20 are held by the mounting head 107 and mounted on the substrate 103, and a component replenishment step (S104 to S108) in which the case 10 is replaced with the components remaining in the attachment 30. ) And.

The case 10 is an example of the first accommodating portion, and the attachment 30 is an example of the second accommodating portion.

As a result, the case 10 can be replaced with the parts remaining in the attachment 30 (specifically, the transport unit 34). For example, when the case 10 is replaced during the mounting process, the case 10 can be replaced while continuing the mounting with the parts remaining inside the attachment 30. That is, when the case 10 is replaced, it is possible to suppress a decrease in productivity in the mounting process. Therefore, it is possible to suppress a decrease in productivity in the mounting process as compared with the case where the case 10 is replaced after the parts in the attachment 30 are exhausted.

Further, the component supply process is executed while the components are mounted on the substrate 103 continuously in time in the mounting process.

As a result, the mounting process and the parts supply process are performed in parallel. The case 10 can be replaced while continuing the mounting process, that is, while mounting the components on the substrate 103 continuously in time. That is, the case 10 can be replaced without stopping the mounting process. Therefore, as compared with the case where the mounting process is stopped and the case 10 is replaced, the decrease in productivity can be suppressed more reliably.

Further, in the parts replenishment process, the cover 11 provided in the opening 15 of the case 10 is opened and closed based on the output of the integrated control device 50 for confirming the remaining number of parts.

The integrated control device 50 is an example of a confirmation unit. Further, the output of the integrated control device 50 may be a determination result regarding the remaining number.

As a result, the cover 11 of the case 10 is opened and closed based on the remaining number of parts (for example, the remaining number of parts in the case 10 or the attachment 30). Therefore, for example, when the case 10 is replaced, other parts are added to the case 10. Can be suppressed from being mixed.

Further, in the parts supply process, the cover 11 is opened and closed based on the type of parts housed in the case 10.

As a result, for example, if a case accommodating a part different from the part to be used is mistakenly attached to the attachment 30, the cover 11 of the case can be kept closed, so that the part can be kept closed in the attachment 30. Can be suppressed from being mixed. That is, it is possible to suppress the corresponding work when the parts are mixed in the attachment 30. Therefore, it is possible to suppress a decrease in productivity due to such a corresponding work.

Further, in the parts supply step, the opening 32b of the mounted portion 32 in a state where the case 10 is removed from the mounted portion 32 of the feeder 20 is closed by the cover 32a.

This makes it possible to prevent other parts from being mixed into the attachment 30 after the case 10 is removed from the attachment 30 and before a new case 10 is attached in the parts supply process. That is, it is possible to suppress the corresponding work when the parts are mixed in the attachment 30. Therefore, it is possible to suppress a decrease in productivity due to such a corresponding work.

Further, as described above, in the mounting system 1 according to the present embodiment, the case 10 for accommodating the bulk state parts is detachable, and the feeder 20 has the attachment 30 for accommodating the parts supplied from the case 10. A mounting head 107 that holds the components supplied by the feeder 20 and mounts the components on the substrate 103, and a control unit 51 that controls the replacement of the case with the components remaining on the attachment 30 are provided.

This has the same effect as the above mounting method. That is, it is possible to suppress a decrease in productivity in the mounting process as compared with the case where the case 10 is replaced after the parts in the attachment 30 are exhausted.

(Variation example 1 of the embodiment)
Next, the configuration of the case 210 according to this modification will be described with reference to FIGS. 18 and 19. FIG. 18 is a perspective view showing the appearance of the case 210 according to the present modification. FIG. 19 is a diagram schematically showing a state in which the case 210 according to this modification is attached to the feeder main body portion 240. The case 210 according to this modification is different from the case 10 according to the embodiment in that it mainly has a transport portion 234. Hereinafter, the case 210 according to the present modification will be described focusing on the differences from the case 10 according to the embodiment. Further, the same or similar configuration as the case 10 according to the embodiment is designated by the same reference numeral as the case 10 according to the embodiment, and the description thereof will be omitted or simplified.

As shown in FIGS. 18 and 19, the case 210 has a transport unit 234 in addition to the case 10 according to the embodiment. That is, in the case 210, the case main body portion 12 and the transport portion 234 are integrally formed. This is an example in which the transport unit 234 is provided for each part housed in the case 210.

The transport unit 234 transports the parts supplied from the case main body 12 to the position where they are taken out by the mounting head 107. In this modification, the transport unit 234 transports the parts from the case main body portion 12 to the opening 235a. The transport unit 234 transports parts by the vibration generated by the vibration generation unit 41. The transport unit 234 is an example of a component transport unit. The cover 235 covers the opening 235a and is in a closed state until mounting is performed.

The case 210 may have a cover 11 at the boundary between the case main body portion 12 and the transport portion 234. In FIG. 18, the cover 11 is not shown. The cover 11 may not be provided.

The second convex portion 218 is a long convex portion provided from the case main body portion 12 to the lower surface of the transport portion 234. For example, a second convex portion 218 is formed by forming a long notch 219 in the longitudinal direction of the case 210 from the case main body portion 12 to the lower surface of the transport portion 234.

The feeder main body 240 is an object to which the case 210 can be attached and detached.

As shown in FIG. 19, the feeder main body 240 has a rod body 246 in addition to the feeder main body 40 according to the embodiment. Further, the feeder main body 240 has a drive unit 245 instead of the drive unit 45.

The drive unit 245 moves the rod body 246 provided so as to press one end of the cover 11 along the X-axis direction under the control of the control unit 51. The drive unit 245 brings the cover 11 from the closed state to the open state by physically acting the rod body 246 on the cover 11 in a state where the case 210 is attached to the feeder main body unit 240. The drive unit 245 is realized by, for example, an actuator. The rod body 246 is an example of an acting portion that acts on the cover 11 provided in the opening 15 of the case 10. The drive unit 245 may have the function of the drive unit 45 according to the embodiment.

As described above, even when the case 210 in which the transport unit 234 is integrated is used, it is possible to suppress the deterioration of workability in opening and closing the cover 11 of the case 210. Further, since the transport unit 234 is integrated with the case 210, the step of attaching the case and the attachment can be omitted, so that the deterioration of workability can be further suppressed.

(Modification 2 of the embodiment)
Next, the configuration of the attachment 330 according to this modification will be described with reference to FIG. 20. FIG. 20 is a diagram schematically showing how the case 10 according to this modification is attached to the attachment 330. The attachment 330 according to the present modification is different from the attachment 30 according to the embodiment in that it mainly has a cover 333 that changes from the closed state to the open state in conjunction with the case 10 being attached to the attachment 330. Hereinafter, the attachment 330 according to the present modification will be described focusing on the differences from the attachment 30 according to the embodiment. Further, the same or similar configuration as the attachment 30 according to the embodiment is designated by the same reference numeral as the attachment 30 according to the embodiment, and the description thereof will be omitted or simplified.

FIG. 20A shows a state in which the case 10 is being attached to the attachment 330. As shown in FIG. 20 (a), the attachment 330 is provided in the opening 32b (see FIG. 20 (b)) and has a cover 333 that opens and closes by moving in the X-axis direction. The cover 333 moves along the direction in which the case 10 extends (X-axis direction) by being physically acted on by the case 10. The cover 333 has an inclined surface 333a corresponding to the inclined surface 330a formed inside the mounted portion 332. At least a part of the inclined surfaces 330a and 333a are in contact with each other.

FIG. 20B shows a state in which the case 10 is attached to the attachment 330. As shown in FIG. 20 (b), the cover 333 moves along the inclination of the inclined surface 330a by moving the case 10 to the plus side of the X-axis. For example, in the example of (b) of FIG. 20, the cover 333 moves to the upper right. Therefore, the opening 32b appears below the cover 333. The parts from the case 10 are supplied to the transport portion 34 of the attachment 330 through the opening 32b.

As described above, the attachment 330 includes a mounted portion 332 to which the case 10 for accommodating the bulk parts is detachably attached. The case 10 has a side surface 10a (an example of the acting portion) that acts on the cover 333 provided in the opening 32b of the mounted portion 332. The side surface 10a physically acts on the cover 333 according to the operation of the case 10 being attached to the attachment 330, thereby changing the cover 333 from the closed state to the open state. For example, the cover 333 changes from the closed state to the open state in conjunction with the operation in which the case 10 is attached to the attachment 330. The side surface 10a may be configured to include, for example, the cover 11.

Further, when the case 10 is removed from the attachment 330, the cover 333 moves to the lower left along the inclined surface 333a, and the opening 32b is automatically closed. A spring for urging the cover 333 of the attachment downward may be provided on the attachment, and the cover 333 may move along the inclined surface 333a by the urging force of the spring.

As a result, the cover 333 of the attachment 330 can be opened from the closed state by simply attaching the case 10 to the attachment 330 without performing an operation for opening and closing the cover 333, so that workability is reduced. It is further suppressed.

Note that the attachment 330 may have a relay chamber 334 formed between the transport unit 34 to which the parts are transported and the case 10. The relay chamber 334 is provided on a supply path in which parts are supplied from the opening 15 of the case 10 to the transport unit 34. The sensor 140 may be provided, for example, so as to be able to detect a component in the relay chamber 334.

In a mounting system having such an attachment 330, when the operation shown in FIG. 13 of the embodiment is performed, the case 10 (an example of the first accommodating portion) is based on the output of the sensor 140 provided in the relay chamber 334. The cover 11 provided in the opening 15 may be opened and closed (corresponding to steps S104 and S108 shown in FIG. 13).

As described above, the attachment 30 of the mounting system according to this modification has a relay chamber 334 between the transport unit 34 to which the parts are transported and the case 10. In the mounting method according to this modification, the integrated control device 50 confirms the remaining number of parts in the relay chamber 334 in the parts supply step.

The attachment 30 is an example of a second accommodating unit, the transport unit 34 is an example of a parts transport unit, and the integrated control device 50 is an example of a confirmation unit.

This makes it possible to replace the case 10 according to the remaining number of parts in the relay chamber 334 on the upstream side (case 10 side) of the transport unit 34 or the presence or absence of parts. For example, the case 10 can be replaced while the number of parts in the case 10 is small or zero, but more parts remain in the transport unit 34. Therefore, the certainty that the replacement of the case 10 is completed before the parts in the transport unit 34 are exhausted is increased.

(Variation example 3 of the embodiment)
Next, the configuration of the attachment 430 according to this modification will be described with reference to FIG. 21. FIG. 21 is a diagram for explaining the opening and closing of the cover 433 of the attachment 430 according to the present modification. FIG. 21 is a schematic partial cross-sectional view of the case 10 and the attachment 430 according to the modified example cut in the XZ plane. The attachment 430 according to the present modification is the attachment 30 according to the embodiment in that the cover 433 of the attachment 430 is configured to open and close in conjunction with the opening and closing of the cover 11 of the case 10. It's different. Hereinafter, the attachment 430 according to the present modification will be described focusing on the differences from the attachment 30 according to the embodiment. Further, the same or similar configuration as the attachment 30 according to the embodiment is designated by the same reference numeral as the attachment 30 according to the embodiment, and the description thereof will be omitted or simplified.

In FIG. 21A, it is assumed that the case 10 is attached to the attachment 430 and the collation work is being performed. In this state, since the rod body 33 is housed in the mounted portion 432, the cover 11 remains in the closed state.

The cover 433 is provided so as to cover the opening 433a. In this modification, the cover 433 comes into contact with the cover 11 due to the urging force of the elastic body 434. The elastic body 434 is, for example, a coil spring, but is not limited thereto. A part of the lower surface (the surface on the minus side of the Z axis) of the cover 433 covers the opening 433a (exposed to the transport portion 34). The cover 433 is an example of the second cover.

FIG. 21B shows a state in which the collation is successful, the rod body 33 is pushed out by the drive unit 45, and the cover 11 is rotated clockwise by the rod body 33. Here, since the cover 11 and the cover 433 are in contact with each other, the cover 11 moves (slides) to the X-axis plus side against the urging force of the elastic body 434 by the rotation of the cover 11. As a result, the cover 433 also changes from the closed state to the open state in conjunction with the change of the cover 11 from the closed state to the open state.

The elastic body 434 may have a spring constant such that the cover 433 can be moved by the rotation of the cover 11. Further, from the viewpoint of suppressing component clogging in the opening 433a, the cover 433 is X-axis by the cover 11 when the length L or less of the lower surface portion exposed to the transport portion 34 when the cover 433 is closed in the X-axis direction. It should be configured so that it can be moved to the plus side.

Further, when the cover 11 is closed, the rod body 33 is pushed back by the drive unit 45, and the cover 11 rotates counterclockwise. Here, the cover 433 receives the urging force of the elastic body 434 and the X-axis minus moves to the side (for example, slides). As a result, the cover 433 also changes from the open state to the closed state in conjunction with the change of the cover 11 from the open state to the closed state. From the viewpoint of preventing the mixing of parts, the cover 11 is configured to be in the closed state from the open state and to drop the parts adhering to the side surface of the cover 433 to the transport portion 34.

As described above, the cover 433 according to the present modification opens and closes in conjunction with the opening and closing of the cover 11 by the cover 11 (an example of the working portion). It can be said that the cover 433 opens and closes by the physical action of the cover 11.

As described above, in the feeder according to this modification, the cover 433 closes and opens in conjunction with the opening and closing of the cover 11 by the rod body 33. The cover 433 is an example of the second cover, the rod 33 is an example of the working portion, and the cover 11 is an example of the first cover.

As a result, when both the case 10 and the mounted portion 432 have a cover, the cover 433 can be opened and closed without performing an operation (or control) for opening and closing the cover 433, which reduces workability. Can be further suppressed.

Although the example in which the acting portion is provided on the mounted portion 432 has been described above, the present invention is not limited to this, and the acting portion may be provided on the case 10. The acting portion provided in the case 10 physically acts on the cover 433 of the mounted portion 432 to open the cover 433. The cover 11 of the case 10 is in contact with the cover 433 and may be opened in conjunction with the opening of the cover 433. In this case, the cover 11 may rotate inside the case 10. Further, the cover 11 may be closed in conjunction with the closing of the cover 433. Further, in this case, the cover 433 is an example of the first cover, and the cover 11 is an example of the second cover.

(Variation example 4 of the embodiment)
When installing an antenna for each RF tag in a mounting system, if the number of feeders provided in the mounting system increases, the number of antennas, cables connecting the antenna and the reader (for example, coaxial cable), and the number of ports of the reader will increase. There are issues such as Therefore, in this modification, a mounting system in which an increase in at least one of the antennas, cables, and ports is suppressed will be described with reference to FIGS. 22 to 25. For example, the mounting system according to this modification is configured to be able to detect a plurality of RF tags with one antenna.

By suppressing the increase in the number of antennas, it is possible to reduce costs related to antennas (for example, costs related to boards, connectors, high frequency wiring, dicing processing, incorporation, wiring routing, etc.). Further, by suppressing the increase in the number of antennas, it is possible to reduce the cost related to the reading device 130 (for example, the cost of the switching port, the expansion board, etc.). Further, as a mounting system, it is possible to reduce the control difficulty level, the detection time, and the like, and the real-time performance is improved accordingly. By suppressing the increase in the number of ports, there is also an effect that the increase in the port switching time can be suppressed.

For example, the arrangement of the antenna and the RF tag is not limited to the arrangement shown in FIG. 12, and may be the arrangement described below. FIG. 22 is a schematic partial cross-sectional view for explaining a first example of arrangement of an antenna and an RF tag according to this modification.

As shown in FIG. 22, the reading device 530 included in the supply unit has a reading unit 131 and a switching unit 532. Further, the reading device 530 has antennas a1 and a2.

The switching unit 532 selects either the antennas a1 and a2 connected to the reading unit 131 in order for the reading unit 131 to switch the RF tag for reading the tag information. It can also be said that the switching unit 532 selects an antenna that can read the tag information from the RF tag in order to read the tag information from the RF tag to be read.

As described above, in this modification, the number of antennas a1 and a2 directly connected to the reader 530 is smaller than the number of RF tags T1 to T3 provided in the case 10, the attachment 30, and the feeder main body 40.

Antenna a1 may read tag information from each of a plurality of RF tags. The antenna a1 may read tag information from each of the RF tags T1 and T3, for example. In this case, for example, the RF tags T1 and T3 may be arranged at positions where at least a part of them does not overlap in a plan view. For example, the RF tags T1 and T3 may be arranged at positions that do not overlap each other in a plan view. Further, it is preferable that no radio wave shield is arranged between the antenna a1 and the RF tag T1 and between the antenna a1 and the RF tag T3. Further, the antenna a1 and the RF tag T1 and the antenna a1 and the RF tag T3 are arranged so as to be electrically coupled to each other.

The antenna a2 is the same as the antenna a2 shown in FIG. 12, and the description thereof is omitted, but signals can be transmitted to and received from the RF tag T2 via the antenna a4, the cable C3, and the antenna a3. The antenna a2 is an example of the second antenna, and the antenna a4, the cable C3, and the antenna a3 are examples of the first transmission unit that transmits the signal of the antenna a2.

The antennas a1 and a2 may be realized by different substrates on which the antenna pattern (for example, see the antenna pattern m1 shown in FIG. 27 described later) is formed, or may be realized by one substrate on which the antenna pattern is formed. You may. When the antennas a1 and a2 are realized by one substrate, an antenna pattern corresponding to the antenna a1 and an antenna pattern corresponding to the antenna a2 are formed on the substrate. The two antenna patterns may be formed on the same surface of the substrate, for example. Further, the two antenna patterns may be provided so that the polarizations intersect in a plan view, or may be formed so that the polarizations are orthogonal to each other, for example. Further, the two antenna patterns may be provided so that the polarizations are parallel in a plan view.

As described above, the reading device 530 according to the present modification may have an antenna a1 configured to detect the RF tag T1 and the RF tag T3.

The RF tag T1 is an example of a first RF tag, the RF tag T3 is an example of a second RF tag, and the antenna a1 is an example of a first antenna.

This makes it possible to reduce the number of antennas that the reader 530 has. Therefore, the configuration of the reading device 530 can be simplified.

Further, the mounting system may be provided in the feeder main body 40 and may further include an antenna a4, a cable C3, and an antenna a3 capable of transmitting a signal from the reader 530 to the RF tag T2. The RF tag T1 may be detected directly by the reader 530, and the RF tag T2 may be detected by the reader 530 via the antenna a4, the cable C3 and the antenna a3. Note that direct detection means that signals can be transmitted and received without going through an antenna other than the antenna connected to the switching unit 532, that is, the target is targeted without going through an antenna other than the antenna connected to the switching unit 532. It means that the RF tag can be detected.

The RF tag T2 is an example of the second RF tag, and the antenna a4, the cable C3, and the antenna a3 are examples of the first transmission unit.

This increases the degree of freedom in the placement of the RF tag T2.

Further, the antenna a1 and the antenna a2 may be formed on one substrate (for example, the substrate aa3 shown in FIG. 27).

This makes it possible to reduce the number of cables for connecting the antennas a1 and a2 to the reading device 530 (for example, the switching unit 532).

FIG. 23 is a schematic partial cross-sectional view for explaining a second example of the arrangement of the antenna and the RF tag according to this modification. The supply unit shown in FIG. 23 includes an antenna a7, a cable C5, and an antenna a6 in addition to the supply unit shown in FIG. The antenna a7, the cable C5, and the antenna a6 are examples of the second transmission unit.

As shown in FIG. 23, the antenna a1 can directly send and receive a signal to the RF tag T1, and can also send and receive a signal to the RF tag T3 via the antenna a7, the cable C5, and the antenna a6. There may be. The feeder main body 40 may be provided with two different transmission units (first transmission unit and second transmission unit). The first transmission unit is a transmission unit for the RF tag T2 provided in the case 10, and the second transmission unit is a transmission unit for the RF tag T3 provided in the attachment 30.

The antenna a1 is configured so that the power of the RF tag T3 increases, the difficulty of detection decreases, and the antenna a1 can be easily detected via the antenna a7, the cable C5, and the antenna a6.

It should be noted that the acquisition of the information of the RF tag T2 via the first transmission unit may be performed only once, for example. The information of the RF tag T2 may be performed once, for example, before the production using the parts housed in the case 10 provided with the RF tag T2. In other words, the reading device 130 does not have to acquire the information of the RF tag T2 during the production using the component.

As described above, the feeder 20 of the mounting system has a feeder main body 40 and an attachment 30 having an attached portion 32 that is removable from the feeder main body 40 and to which the case 10 is detachably attached. You may be doing it. Further, even if the mounting system is provided in the feeder main body 40 and further includes an antenna a7, a cable C5, and an antenna a6 capable of transmitting a signal from the reader 530 to the RF tag T3 provided inside the attachment 30. good.

The case 10 is an example of the housing.

As a result, the reading device 530 can easily detect the RF tag T3 whose power of the RF tag T3 has increased and the difficulty of detection has decreased. Further, the degree of freedom in arranging the RF tag T3 is increased. For example, if the mounting system includes a first transmission unit and a second transmission unit, the degree of freedom in arranging the RF tags T2 and T3 is increased.

Further, the antenna a1 may be configured to further detect the RF tag T3 via the antenna a7, the cable C5, and the antenna a6.

This makes it possible to reduce the number of antennas that the reader 530 has. Therefore, the configuration of the reading device 530 can be simplified.

FIG. 24 is a schematic partial cross-sectional view for explaining a third example of the arrangement of the antenna and the RF tag according to this modification. In FIG. 23, one antenna transmits / receives signals to / from the RF tag T1 provided in the feeder main body 40 and the RF tag T3 provided in the attachment 30, but the antenna a3 according to this modification is Signals can be transmitted and received to the RF tag T3 provided on the attachment 30 and the RF tag T2 provided on the case 10.

As shown in FIG. 24, the antenna a2 may be capable of transmitting and receiving signals to and from the RF tags T2 and T3 via the antenna a4, the cable C3, and the antenna a3. The antenna a3 is configured to be capable of transmitting and receiving signals to and from the RF tag T3 provided inside the attachment 30 in addition to the RF tag T2. The antenna a4, the cable C3, and the antenna a3 are examples of the first transmission unit.

As described above, the feeder 20 has a feeder main body 40 and an attachment and 30 having an attached portion 32 that can be attached to and detached from the feeder main body 40 and to which the case 10 can be attached and detached. You may. Then, in addition to transmitting the signal to the RF tag T2 provided in the case 10, the antenna a3 may further transmit a signal to the RF tag T3 provided inside the attachment 30.

This makes it possible to reduce the number of antennas provided inside the attachment 30. Therefore, the configuration of the supply unit can be simplified.

FIG. 25 is a schematic partial cross-sectional view for explaining a fourth example of the arrangement of the antenna and the RF tag according to this modification.

As shown in FIG. 25, the reading device 630 has a reading unit 131. The reading unit 131 is connected to the antenna a1. That is, the reading device 630 has one antenna a1. For example, the reading device 630 does not have a switching unit.

The RF tag T1 is directly detected by the reading device 630, the RF tag T2 is detected by the reading device 630 via the antenna a4, the cable C3 and the antenna a3, and the RF tag T3 has the antenna a7, the cable C5 and the antenna a6. It may be detected by the reading device 630 via the reader.

As described above, the antenna a1 may be configured to detect each of the RF tags T1, T2, and T3. That is, the antenna a1 may have a configuration capable of transmitting a signal to each of the RF tags T1, T2, and T3.

This makes it possible to further reduce the number of antennas possessed by the reader 630. Therefore, the configuration of the reading device 630 can be further simplified.

(Variation example 5 of the embodiment)
When installing an antenna for each RF tag in a mounting system, if the number of feeders provided in the mounting system increases, the number of antennas, cables connecting the antenna and the reader (for example, coaxial cable), and the number of ports of the reader will increase. There are issues such as Therefore, in this modification, a mounting system in which an increase in at least one of the antennas, cables, and ports is suppressed will be described with reference to FIGS. 26 to 38. For example, the mounting system according to this modification has a configuration in which a plurality of RF tags can be detected by one antenna installed for each feeder surrounded by metal (for example, for each feeder main body). For example, the mounting system according to this modification solves the above problem by devising a transmission path provided inside the attachment 30.

FIG. 26 is a diagram schematically showing a supply unit according to this modification. FIG. 26 shows the case 10, the attachment 30, and the feeder main body 40 of the supply unit 80. Further, FIG. 26 (a) is a side view of the supply unit 80 as viewed from the Y-axis direction, and FIG. 26 (b) shows the supply unit 80 along the XXVIb-XXVIb line shown in FIG. 26 (a). It is a cut sectional view. 26 (a) and 26 (b) show a configuration for the antenna a2 to send and receive signals to and from the RF tags T2 and T3 via the antenna a4, the cable C3, and the antenna a3 (an example of the first transmission unit). ..

As shown in FIGS. 26A and 26B, the supply unit 80 includes an antenna a2 provided outside the feeder main body 40, and an antenna a3, an antenna a4, and a cable C3 provided inside the feeder main body 40. It has an RF tag T3 and a relay board 750 provided inside the attachment 30, and an RF tag T2 provided inside the case 10. The RF tag T2 may be provided outside the case 10, for example.

The antenna a2 is provided on the trolley 70, for example, and can transmit and receive signals to the RF tags T2 and T3 via the antenna a4, the cable C3, and the antenna a3. The antenna a2 is connected to the reading device 130. The antenna a2 is provided with a connector n2 to which a cable C2 (for example, a coaxial cable) for connecting to the reader 130 is connected.

The antenna a4 is arranged so as to face the antenna a2, and a connector n4 to which a cable C3 (for example, a coaxial cable) for connecting to the antenna a3 is connected is provided.

The antenna a3 is arranged so as to face the RF tag T2, and a connector n3 to which the cable C3 for connecting to the antenna a4 is connected is provided.

An opening 40a (radio wave transmitting portion) for transmitting the radio wave from the antenna a3 to the attachment 30 is formed on the attachment 30 side of the feeder main body 40. The opening 40a is formed between the antenna a3 and the relay board 750 or the RF tag T3. The size of the opening 40a may be determined based on the wavelength of the radio wave transmitted from the antenna a4. When the wavelength of the radio wave is 32.6 cm (in a vacuum) (corresponding to a wavelength of 920 MHz), the size of the opening 40a is, for example, about 50 mm in the X-axis direction and a length in the Y-axis direction. It is about 10 mm, but is not limited to this. An opening is also formed between the antennas a2 and a4, but the illustration is omitted.

FIG. 27 is a diagram showing the configuration of the antenna a3 according to this modified example. Although the antenna a3 is described in FIG. 27 among the plurality of antennas, other antennas may have the configuration shown in FIG. 27.

As shown in FIG. 27, the antenna a3 has a substrate aa3 having a connector n3 and an antenna pattern m1. The connector n3 is provided on, for example, the main surface (Z-axis minus side surface) of the substrate TT2 on the antenna a4 side, and the antenna pattern m1 is, for example, the main surface (Z-axis plus side) of the substrate TT2 on the RF tag T2 side. It is provided on the surface). For example, the main surface on which the antenna pattern m1 of the antenna a3 is formed and the main surface on which the antenna pattern m2 of the RF tag T2 is formed are arranged so as to face each other.

The connector n3 is provided, for example, in the center of the substrate aa3. The antenna pattern m1 is a conductor pattern that meanders like a meander, is formed so as to sandwich the connector n3, and is connected to the connector n3. The antenna pattern m1 has a square wave shape, the Y-axis direction is the amplitude direction of the square wave, the X-axis direction is the period (pitch) of the square wave, and the antenna pattern m1 extends along the X-axis direction with the same repeating period. .. Since the antenna pattern m1 has the above shape, radio waves having high electric field strength can be emitted in the direction orthogonal to the substrate aa3 (for example, in the antenna a3 alone, the Y-axis direction and the Z-axis direction). The polarization of the antenna a3 is in the same direction (X-axis direction) as the extending direction of the antenna pattern m1.

The length L1 of the antenna a3 in the Y-axis direction is determined, for example, based on the width of the void inside the feeder main body 40 or the attachment 30. Further, the length L3 of the antenna a3 in the X-axis direction is, for example, the length of the opening (for example, the second radio wave transmitting portion 730b) formed in the opening 40a of the feeder main body 40 or the attachment 30 (in the X-axis direction). It is determined based on the length). Further, the plan view shape of the antenna a3 is rectangular, but the shape thereof is not limited to this.

With reference to FIG. 26 again, the RF tag T2 is arranged inside the case 10 so as to face the antenna a3. The RF tag T2 transmits / receives a signal to / from the antenna a3 via the relay board 750.

FIG. 28 is a diagram showing the configuration of the RF tag T2 according to this modification. Although the RF tag T2 is described in FIG. 28 among the plurality of RF tags, other RF tags may also have the configuration shown in FIG. 28.

As shown in FIG. 28, the RF tag T2 has a substrate TT2 having an IC chip I and an antenna pattern m2. The IC chip I and the antenna pattern m2 are provided, for example, on the main surface of the substrate TT2 on the antenna a3 side (the main surface on the minus side of the Z axis, which is an example of the second main surface).

The IC chip I is a component provided on the substrate TT2 and is an RFIC chip capable of wireless communication with the reader 130. The IC chip I is configured to communicate at a communication frequency in the UHF band (for example, 920 MHz). Further, the memory of the IC chip I stores information about the parts housed in the case 10.

The antenna pattern m2 is a conductor pattern that meanders like a meander, is formed so as to sandwich the IC chip I, and is connected to the IC chip I. The antenna pattern m2 has a square wave shape, the Y-axis direction is the amplitude direction of the square wave, the X-axis direction is the period (pitch) of the square wave, and the antenna pattern m2 extends along the X-axis direction with the same repeating period. .. Since the antenna pattern m2 has the above shape, radio waves having high electric field strength are emitted in the Z-axis direction orthogonal to the substrate TT2. The polarization of the RF tag T2 is in the same direction (X-axis direction) as the extending direction of the antenna pattern m2. The antenna pattern m2 is connected to the IC chip I. The antenna a3 and the RF tag T2 are arranged so that the polarization of the antenna a3 and the polarization of the RF tag T2 match in a plan view.

When the radio wave in the UHF band is radiated from the antenna a3, the RF tag T2 drives the radio wave as energy and transmits a signal indicating information stored in the IC chip I toward the antenna a3. The signal received by the antenna a3 is transmitted to the reading device 130 via the cable C3, the antennas a3, the a2, and the like.

Note that the IC chip I is not limited to being configured to communicate at a communication frequency in the UHF band, and may be configured to communicate, for example, by microwave.

The length L1 of the RF tag T2 in the Y-axis direction is determined, for example, based on the width of the void inside the feeder main body 40 or the attachment 30. The length L1 of the RF tag T2 is, for example, the same as, but is not limited to, the length L1 of the antenna a3. Further, the length L3 of the RF tag T2 is, for example, the length (length in the X-axis direction) of the opening 40a of the feeder main body 40 or the opening formed in the attachment 30 (for example, the first radio wave transmitting portion 730a). It is decided based on. Further, the plan view shape of the RF tag T2 is rectangular, but the shape thereof is not limited to this. The length L3 of the RF tag T2 is, for example, the same as the length L3 of the antenna a3. For example, the RF tag T2 and the antenna a3 may have the same size. It can be said that the size of the RF tag T2 corresponds to the size of the RF tag T3 provided inside the attachment 30.

The RF tag T3 may be arranged inside the attachment 30 so that, for example, the main surface on which the antenna pattern of the RF tag T3 is formed is orthogonal to the main surface on which the antenna pattern m2 of the RF tag T2 is formed. Even in this case, the polarizations of the RF tags T2 and T3 in the plan view are the same.

With reference to FIG. 26 again, in the RF tag T3, the main surface on which the antenna pattern m2 of the RF tag T3 is formed faces the main surface on which the antenna pattern of the relay board 750 (antenna pattern m3 shown in FIG. 29) is formed. It is arranged inside the attachment 30 so as to do so.

The relay board 750 is arranged between the RF tag T2 and the antenna a3 inside the attachment 30, and transmits radio waves from the antenna a3 to each of the RF tags T2 and T3. Further, the relay board 750 transmits the radio waves received from the RF tags T2 and T3 to the antenna a3.

FIG. 29 is a diagram showing the configuration of the relay board 750 according to this modification.

As shown in FIG. 29, the relay board 750 has a board 750a on which the antenna pattern m3 is formed. The antenna pattern m3 is provided, for example, on the main surface of the substrate 750a on the RF tag T3 side (the surface on the minus side of the Y axis, which is an example of the first main surface). The relay board 750 is, for example, a non-feeding element.

The antenna pattern m3 is a conductor pattern that meanders like a meander. The antenna pattern m3 is a non-feeding element formed on the substrate 750a. The antenna pattern m3 has a square wave shape, the Y-axis direction is the amplitude direction of the square wave, the X-axis direction is the period (pitch) of the square wave, and the antenna pattern m3 extends along the X-axis direction with the same repeating period. .. Since the antenna pattern m3 has the above shape, radio waves having high electric field strength are emitted in the Z-axis direction orthogonal to the substrate 750a. The polarization of the relay board 750 is in the same direction (X-axis direction) as the extending direction of the antenna pattern m3. FIG. 29 shows an example in which four antenna patterns m3 are formed in the substrate 750a, but the number of antenna patterns m3 is not limited to this, and may be 1 or more.

The relay board 750 is arranged so that, for example, the main surface on which the antenna pattern m3 is formed faces the RF tag T3. In the relay board 750, one end (the end on the Z-axis plus side) of the main surface on which the antenna pattern m3 is formed is on the RF tag T2 side, and the other end (the end on the minus side of the Z-axis) of the main surface is. It is arranged so as to be on the antenna a3 side from the one end. Further, the polarization of the relay board 750 and the polarization of the RF tag T3 are arranged so as to match.

The length of the relay board 750 in the Z-axis direction is the length L2, and is determined based on, for example, the height of the attachment 30 (the length in the Z-axis direction). Further, the length of the relay board 750 in the X-axis direction is the length L3, and may be, for example, an integral multiple of the half wavelength (λ / 2) of the radio wave. The length L3 in the X-axis direction of the relay board 750 may be equal to, for example, the length L3 in the X-axis direction of the antenna a3 and the RF tag T2.

The antenna a3 thus arranged, the RF tags T2 and T3, and the relay board 750 have the same polarization (for example, in the X-axis direction) in a plan view, for example.

The electrical length of the antenna pattern m3 on the substrate may be an odd multiple of λ / 2 with respect to the wavelength λ of the operating frequency in consideration of the physical characteristics of the substrate.

Here, an arrangement example of the RF tag T3 and the relay board 750 will be described with reference to FIGS. 30 to 32. FIG. 30 is a cross-sectional view showing a first example of the configuration of the supply unit 80 according to the present modification. Note that FIGS. 30 to 32 show only the case 10, the attachment 30, and the antenna a3 in the cross-sectional view shown in FIG. 26 (b).

As shown in FIG. 30, the supply unit 80 is an attachment 30 having a radio wave shielding portion 730 having a radio wave shielding property and a first radio wave transmitting portion 730a having a radio wave transmitting property, and an RF tag T3 is attached therein. The case 10 to which the RF tag T2 is attached has an attachment 30 provided on the outside of the first radio wave transmitting portion 730a. Further, the attachment 30 has radio wave transmission and has a second radio wave transmitting portion 730b provided so as to face the first radio wave transmitting portion 730a.

The antenna a3 is arranged outside the second radio wave transmitting portion 730b (Z-axis minus side). In the case of the configuration shown in FIG. 30, the feeder 20 provided with the attachment 30 is an example of the first production equipment unit, and the case 10 is the second production equipment unit provided outside the first radio wave transmitting portion 730a. This is just one example.

The radio wave shielding unit 730 is a box-shaped housing that constitutes the outer shell of the attachment 30. The radio wave shielding unit 730 is made of metal from the viewpoint of durability and the like. That is, the radio wave shielding unit 730 has a radio wave shielding property. The radio wave shielding unit 730 is not limited to being made of metal.

The radio wave shielding portion 730 is formed with a first radio wave transmitting portion 730a and a second radio wave transmitting portion 730b, which are portions of the attachment 30 that transmit radio waves. In this modification, the first radio wave transmitting portion 730a and the second radio wave transmitting portion 730b are openings formed in the radio wave shielding portion 730. The first radio wave transmitting portion 730a may have an opening having a length of 50 mm in the X-axis direction and a length of about 10 mm in the Y-axis direction, for example. An opening may also be formed at the position of the case 10 facing the opening. The size of the opening formed in the case 10 in a plan view may be the same as the size of the first radio wave transmitting portion 730a.

The first radio wave transmitting portion 730a is an opening for transmitting (propagating) radio waves from one of the relay board 750 and the RF tag T2 to the other. The second radio wave transmitting portion 730b is an opening for transmitting (propagating) radio waves from one of the antenna a3 and the relay board 750 to the other. The first radio wave transmitting portion 730a is provided between the pair of radio wave shielding portions 730. The first radio wave transmitting portion 730a is provided so as to be passed between the pair of radio wave shielding portions 730 at the ends on the Z-axis plus side of the pair of radio wave shielding portions 730.

The first radio wave transmitting portion 730a and the second radio wave transmitting portion 730b are not limited to being a space (air layer), and may be members having radio wave transmission such as resin. For example, the opening formed in the radio wave shielding portion 730 may be covered with a resin or the like.

In the cross-sectional view shown in FIG. 30, the attachment 30 has a pair of radio wave shielding portions 730 arranged so as to face each other, and a first radio wave transmitting portion 730a and a second radio wave transmitting portion 730a passed between the pair of radio wave shielding portions 730. It can be said that it has a radio wave transmitting portion 730b.

The relay board 750 is arranged between the RF tags T2 and T3. The RF tag T3 is arranged in the second radio wave transmitting portion 730b. One end (Z-axis plus side end) of the main surface on which the antenna pattern m3 of the relay board 750 is formed is the RF tag T2 side, and the other end of the main surface (Z-axis minus side end) is the said. It is arranged so as to be on the RF tag T3 side from one end. The relay board 750 is arranged so as to be orthogonal to each of the RF tags T2 and T3 in the cross-sectional view shown in FIG. Further, the relay board 750 may be arranged at a central position between the pair of radio wave shielding portions 730 in the cross-sectional view shown in FIG. 30, or may be placed on one of the pair of radio wave shielding portions 730, the radio wave shielding portion 730. It may be arranged in a close position. The relay board 750 is arranged so as not to come into contact with the radio wave shielding portion 730.

For example, when there is no relay board 750 between the RF tags T2 and T3 and the inside of the attachment 30 is narrow with respect to the wavelength of the radio wave (for example, a radio wave of 920 MHz), the radio wave propagates from the RF tag T3 to the RF tag T2. It becomes difficult. On the other hand, since the mounting system according to this modification is provided with the relay board 750, the radio wave can be more reliably transmitted to the RF tag T2 even when the inside of the attachment 30 is narrow with respect to the wavelength of the radio wave. ..

The RF tags T2 and T3 are arranged to face each other, and the RF tags T3 and the antenna a3 are arranged to face each other. For example, the antenna a3 and the RF tag T3 are arranged so as to be electric-field-coupled, the RF tag T3 and the relay board 750 are arranged so as to be electric-field-coupled, and the relay board 750 and the RF tag T2 can be electric-field-coupled. Arranged like this.

The antenna a3 is configured to detect the RF tag T3 and to detect the RF tag T2 via the inside of the attachment 30 and the first radio wave transmitting portion 730a.

In the mounting system configured as described above, when radio waves are radiated from the antenna a3 to the RF tag T3, the RF tag T3 radiates a signal including information stored in the IC chip I to the antenna a3 and also emits a signal to the antenna a3. The radio wave from the antenna a3 is propagated to the relay board 750. The relay board 750 propagates the radio wave from the RF tag T3 to the RF tag T2, and propagates the signal received from the RF tag T2 to the RF tag T3. The RF tag T3 propagates the signal received from the relay board 750 to the antenna a3. As a result, the antenna a3 can receive signals indicating information stored in the IC chip I from each of the RF tags T2 and T3.

Note that the RF tag T3 is not limited to being arranged between the relay board 750 and the antenna a3. The RF tag T3 may be arranged at a position that does not overlap with the RF tag T2, the antenna a3, and the relay board 750 in a plan view, and may be arranged so as to be electrically coupled to an antenna different from the antenna a3. In this case, the radio wave from the antenna a3 is directly propagated to the relay board 750.

As described above, the mounting system has a main surface on which the antenna pattern m3 is formed, and may further include a relay board 750 provided inside the attachment 30. The RF tag T3 is provided so as to face the RF tag T2, the relay board 750 is provided between the RF tag T2 and the RF tag T3, and one end of the main surface is arranged on the RF tag T2 side. The other end of the main surface may be arranged on the RF tag T3 side from the one end. Then, the RF tag T2 may be detected by the antenna a3 via the RF tag T3 and the relay board 750.

The main surface on which the antenna pattern m3 is formed is an example of the first main surface, the RF tag T2 is an example of the second RF tag, and the RF tag T3 is an example of the third RF tag. be.

As a result, since the relay board 750 is arranged between the RF tags T2 and T3, it is possible to suppress the attenuation of radio waves between the RF tags T2 and T3 (suppress the propagation loss). That is, it is possible to transmit and receive signals to and from each of the RF tags T2 and T3 by using one antenna a3. Therefore, since the number of antennas provided in the mounting system can be reduced, it is possible to suppress an increase in the number of ports of the antenna, the cable connecting the antenna and the reading device, and the reading device.

Subsequently, other configurations of the supply unit will be described with reference to FIG. 31. FIG. 31 is a cross-sectional view showing a second example of the configuration of the supply unit according to the present modification.

As shown in FIG. 31, the RF tag T3 is not limited to being arranged so as to face the antenna a3, and may be arranged so as to face the relay board 750. For example, one end (the end on the Z-axis plus side) of the main surface (for example, the main surface on the Y-axis plus side) on which the antenna pattern m2 of the RF tag T3 is formed is on the RF tag T2 side, and the main surface is The other end (the end on the minus side of the Z axis) is arranged so as to be on the antenna a3 side from the one end. The RF tag T3 may be arranged so as to be orthogonal to each of the antenna a3 and the RF tag T2 in the cross-sectional view shown in FIG.

The RF tag T3 is arranged between the relay board 750 and one of the radio wave shielding portions 730 in the cross-sectional view shown in FIG. The RF tag T3 may be arranged, for example, at a central position between the relay board 750 and one radio wave shielding portion 730, or may be located at a position closer to the relay board 750 among the relay board 750 and one radio wave shielding portion 730. It may be arranged in the relay board 750 and one of the radio wave shielding portions 730 at a position close to one of the radio wave shielding portions 730.

The RF tag T3 and the relay board 750 are not arranged in the direction in which the RF tag T2 and the antenna a3 are arranged (Z-axis direction). In other words, the RF tag T3 and the relay board 750 are arranged at positions that do not overlap in a plan view. The RF tag T3 and the relay board 750 are arranged side by side in the direction (Y-axis direction) in which the pair of radio wave shielding portions 730 are lined up.

The RF tags T2 and T3, the antenna a3, and the relay board 750 are arranged so that their polarizations match in a plan view. Further, for example, the RF tag T2 and the antenna a3 are arranged so that the main surfaces on which the antenna pattern is formed face each other, and the RF tag T3 and the relay board 750 face each other on the main surfaces on which the antenna pattern is formed. It may be arranged. For example, the antenna a3 and the relay board 750 are arranged so as to be electric field-coupled, and the relay board 750 and the RF tags T2 and T3 are arranged so as to be electric-field-coupled.

The relay board 750 is arranged between the RF tag T2 and the antenna a3 inside the attachment 30, and transmits radio waves from the antenna a3 to each of the RF tags T2 and T3. Further, the relay board 750 transmits the radio waves received from the RF tags T2 and T3 to the antenna a3. When the radio wave in the UHF band is radiated from the antenna a3, the RF tag T2 drives the radio wave as energy and transmits a signal indicating information stored in the IC chip I toward the antenna a3. The signal received by the antenna a3 is transmitted to the reading device 130 via the cable C3, the antennas a3, the a2, and the like. The relay board 750 is an example of a transmission unit.

By providing the relay board 750, even when the second radio wave transmitting portion 730b (for example, an opening) is small and it is difficult for the radio wave to enter the inside of the attachment 30, the radio wave can be penetrated more reliably. can. That is, the provision of the relay board 750 increases the certainty that the RF tag T2 can be read.

The relay board 750 does not intentionally prevent the antenna a3 and the RF tag T3 from being directly field-coupled.

The RF tag T3 should not come into contact with the radio wave shielding unit 730.

The tag reading system 800 is composed of the attachment 30 and the antenna a3. The tag reading system 800 is a system configured to detect the RF tag T2 using the relay board 750. The tag reading system 800 is configured, for example, so that the antenna a3 detects the RF tag T2 via the inside of the attachment 30 provided with the relay board 750 and the first radio wave transmitting portion 730a. In the tag reading system 800, the attachment 30 is an example of a first production equipment unit, and the case 10 is an example of a second production equipment unit. The tag reading system 800 does not have to include the second production equipment unit.

In the mounting system configured as described above, when the radio wave is radiated from the antenna a3 to the relay board 750, the relay board 750 propagates the radio wave from the antenna a3 to the RF tags T2 and T3. Then, the relay board 750 receives a signal corresponding to the radio wave from each of the RF tags T2 and T3, and propagates the signal to the antenna a3. As a result, the antenna a3 can receive a signal indicating the tag information stored in the IC chip I from each of the RF tags T2 and T3.

In the above, in the mounting system, the relay board 750 is provided inside the attachment 30, and the RF tag T2 provided in the case 10 is detected via the relay board 750. However, the mounting system configuration (tag reading system 800). The configuration of) is not limited to this. For example, the relay board 750 may be provided in the feeder main body 40, and may be configured to detect the RF tag T3 provided inside the attachment 30 via the relay board 750.

As described above, the mounting system has a main surface on which the antenna pattern m3 is formed, and may further include a relay board 750 provided inside the attachment 30. In the relay board 750, one end of the main surface may be arranged on the RF tag T2 side (Z-axis plus side), and the other end of the main surface may be arranged on the antenna a3 side (Z-axis minus side) from the one end. .. Then, the RF tag T2 is detected by the antenna a3 via the relay board 750. For example, each of the RF tags T2 and T3 may be detected by the antenna a3 via the relay board 750.

The main surface on which the antenna pattern m3 is formed is an example of the first main surface, the antenna a3 is an example of the third antenna, and the RF tag T2 is an example of the second RF tag. The RF tag T3 is an example of a third RF tag.

As a result, in the mounting system, the RF tag T3 is not arranged between the relay board 750 and the antenna a3, so that the distance between the relay board 750 and the antenna a3 can be shortened. That is, it is possible to suppress the attenuation of the radio wave between the relay board 750 and the antenna a3, and it is possible to improve the received signal strength of the RF tags T2 and T3. Therefore, the mounting system can more reliably transmit the radio wave to the RF tags T2 and T3 even when the inside of the attachment 30 is narrow with respect to the radio wave.

Further, the tag reading system 800 is an attachment 30 having a radio wave shielding unit 730 having a radio wave shielding property and a first radio wave transmitting unit 730a having a radio wave transmitting property, and an RF tag T3 is attached therein, and is an RF tag. The case 10 to which the T2 is attached includes an attachment 30 provided outside the first radio wave transmitting portion 730a, and an antenna a3 for detecting the RF tags T2 and T3. The RF tag T3 has a main surface on which the antenna pattern m2 is formed, one end of the main surface is on the RF tag T2 side, and the other end of the main surface is arranged on the antenna a3 side from the one end. Then, the antenna a3 is configured to detect the RF tag T2 via the inside of the attachment 30 and the first radio wave transmitting portion 730a.

The RF tag T2 here is an example of a second RF tag, and the RF tag T3 is an example of a first RF tag. Further, the attachment 30 is an example of a first production equipment unit, the case 10 is an example of a second production equipment unit, and the main surface on which the antenna pattern m2 is formed is an example of the first main surface. ..

As a result, in the tag reading system 800, the antenna a3 can detect the RF tag T2 via the inside of the attachment 30 and the first radio wave transmitting portion 730a, so that the attachment 30 has the radio wave shielding portion 730. Even if there is, the information of the RF tag T2 provided in the case 10 can be acquired more reliably. Further, the tag reading system 800 can also write information to the RF tag T2 more reliably by passing through the inside of the attachment 30 and the first radio wave transmitting portion 730a.

Further, the tag reading system 800 further includes a relay board 750 in which the attachment 30 is internally arranged between the RF tag T2 and the antenna a3 and has a main surface on which the antenna pattern m3 is formed. In the relay board 750, one end of the main surface is arranged on the RF tag T2 side, and the other end of the main surface is arranged on the antenna a3 side from the one end. Then, the RF tag T2 is detected by the antenna a3 via the relay board 750.

The main surface on which the antenna pattern m3 is formed is an example of the first main surface.

Further, the attachment 30 has radio wave transmission and includes a second radio wave transmission unit 730b provided so as to face the first radio wave transmission unit 730a. Then, the antenna a3 is arranged outside the second radio wave transmitting portion 730b.

Further, the first production equipment unit is a feeder 20 having a mounted portion (for example, the mounted portion 32 shown in FIG. 3) on which the case 10 is mounted, and the second production equipment unit accommodates parts. Case 10 may be used.

As a result, the RF tag T2 provided in the case 10 can be read more reliably.

Further, the tag reading system 800 further includes a second production equipment unit. The first production equipment unit is a feeder main body 40 to which a case 10 for accommodating parts is mounted via an attachment 30, and the second production equipment unit has a mounted portion 32 to which the case 10 is mounted. It may be the attachment 30.

As a result, the RF tag T3 provided on the attachment 30 can be read more reliably.

Further, in the mounting system according to this modification, the substrate transport mechanism 102 holding the substrate 103, the tag reading system 800 described above, and the first tag information based on the RF tag T2 read by the tag reading system 800, Based on the determination results of the first control device 50a or the integrated control device 50 for determining the correctness of the component and the first control device 50a or the integrated control device 50 based on the information of the second tag based on the RF tag T3. Further, a mounting head 107 for mounting the components held by the feeder 20 on the substrate 103 may be provided.

The substrate 103 is an example of an object, the substrate transfer mechanism 102 is an example of a holding unit, and the first control device 50a or the integrated control device 50 is an example of a determination unit.

This makes it possible to realize a mounting system that can more reliably read the information of the RF tag T2 provided in the case 10 or the RF tag T3 provided in the attachment 30. Therefore, it is possible to suppress the occurrence of an error in reading the RF tag information, which leads to an improvement in the productivity of the mounting system.

Subsequently, another configuration of the supply unit will be described with reference to FIG. 32. FIG. 32 is a cross-sectional view showing a third example of the configuration of the supply unit according to the present modification.

As shown in FIG. 32, the mounting system is not limited to the relay board 750, and the RF tag T3 may have the function of the relay board 750. In this case, the period of the square wave of the antenna pattern m2 of the RF tag T3 may be shorter than the period of the square wave of the antenna pattern m2 of the RF tag T2, for example. In other words, the RF tag T3 has high antenna performance, and for example, has higher antenna characteristics than the RF tag T2. It can be said that the RF tag T3 has a function as a transmission unit.

In the RF tag T3, one end (the end on the Z-axis plus side) of the main surface (for example, the main surface on the Y-axis plus side) on which the antenna pattern m2 is formed is on the RF tag T2 side, and the other of the main surface. The end (the end on the minus side of the Z axis) is arranged so as to be on the antenna a3 side from the one end. The RF tag T3 may be arranged so as to be orthogonal to each of the antenna a3 and the RF tag T2 in the cross-sectional view shown in FIG.

The RF tag T3 is arranged between the RF tag T2 and the antenna a3 and between one of the radio wave shielding portions 730 in the cross-sectional view shown in FIG. The RF tag T3 may be arranged at a central position between, for example, a pair of radio wave shielding portions 730. For example, the distance between the RF tag T3 shown in FIG. 32 and each of the pair of radio wave shielding portions 730 is the length L4 and is equal. Further, in the RF tag T3, the main surface on which the antenna pattern m2 of the RF tag T3 is formed may be arranged at the central position between the pair of radio wave shielding portions 730. Further, the RF tag T3 may be arranged at a position close to one of the radio wave shielding portions 730 of the pair of radio wave shielding portions 730. Further, the RF tag T3 is arranged at an intermediate position in the Z-axis direction between the RF tag T2 and the antenna a3, for example.

The RF tags T2 and T3 and the antenna a3 are arranged so that their polarizations match in a plan view. For example, the antenna a3 and the RF tag T2 are arranged so as to be electric field-coupled, and the RF tag T3 and the RF tag T2 are arranged so as to be electric-field-coupled.

In the mounting system configured as described above, when the RF tag T3 receives a radio wave from the antenna a3, it radiates a signal corresponding to the radio wave to the antenna a3 and propagates the radio wave to the RF tag T2. Further, when the RF tag T3 receives the signal corresponding to the radio wave from the RF tag T2, the RF tag T3 may propagate the signal to the antenna a3. As a result, the antenna a3 can receive a signal indicating the tag information stored in the IC chip I from each of the RF tags T2 and T3.

As described above, the RF tag T3 of the mounting system has a main surface on which the antenna pattern m2 is formed, and one end of the main surface is arranged on the RF tag T2 side (Z-axis plus side) of the main surface. The other end may be arranged on the antenna a3 side from the one end.

Thereby, the antenna a3 can detect the RF tags T2 and T3 without providing the relay board 750. In other words, it is possible to realize an implementation system with a simpler configuration. This contributes to cost reduction of the mounting system.

Further, the attachment 30 in the tag reading system 800 has a pair of radio wave shielding units 730 arranged so as to face each other, and a first radio wave transmitting unit 730a provided between the pair of radio wave shielding units 730. The main surface on which the antenna pattern m2 of the RF tag T3 is formed is arranged in the center between the pair of radio wave shielding portions 730. The pair of radio wave shielding portions 730 and the main surface of the RF tag T3 may be arranged so as to face each other, for example.

Thereby, the radio wave from the antenna a3 can be propagated to the RF tag T2 by using the antenna pattern m2 formed on the RF tag T3. That is, the radio wave from the antenna a3 can be propagated to the RF tag T2 without providing the relay board 750. Therefore, as compared with the case where the relay board 750 is provided, the internal configuration of the attachment 30 can be simplified, which leads to cost reduction.

The position of the RF tag T3 in the supply unit shown in FIG. 32 is not limited to the central position between the pair of radio wave shielding portions 730. The position of the RF tag T3 will be described with reference to FIGS. 33 and 34. FIG. 33 is a diagram for explaining a method of measuring the received signal strength for each position of the RF tag T3 according to this modification.

As shown in FIG. 33, the received signal strengths of the RF tags T2 and T3 when the position of the RF tag T3 is changed from the radio wave shielding portion 730 side on the minus side of the Y axis to the radio wave shielding portion 730 side on the plus side of the Y axis. To measure. The resin plate r is a member for fixing the position of the RF tag T3, and is a resin plate-shaped member that does not affect the reception signal strength. There are seven resin plates r, and the thickness (length in the Y-axis direction) of each is the same. In the example of FIG. 33, the position of the RF tag T3 is shown when there is one resin plate r between the RF tag T3 and the radio wave shielding portion 730 on the minus side of the Y axis. It is assumed that the RF tags T2 and T3 face each other, and that the RF tag T2 and the antenna a3 and the RF tag T3 are orthogonal to each other in the cross-sectional view shown in FIG. 33. The main surface on which the antenna pattern of the RF tag T3 is formed is the surface on the minus side of the Y-axis.

The RF tag T2 and the antenna a3 are fixed. Further, the intensity of the radio wave radiated from the antenna a3 is constant regardless of the position of the RF tag T3.

FIG. 34 is a diagram showing the measurement results of the received signal strength for each position of the RF tag T3 according to this modification. The "attachment" shown in FIG. 34 indicates the received signal strength (RSSI: Received Signal Strength Indicator) for each position of the RF tag T3 provided in the attachment 30, and the "case" is provided in the case 10. The received signal strength for each position of the RF tag T3 in the RF tag T2 is shown. When the number of resin plates r is 0 and 7, the RF tag T3 is not in contact with the inner surface of the radio wave shielding portion 730, but is arranged so as to have a predetermined interval (for example, about 1 mm). To.

As shown in FIG. 34, it can be seen that the received signal strength of the RF tag T3 is high regardless of the position of the RF tag T3 in the Y-axis direction. On the other hand, the received signal strength of the RF tag T2 is affected by the position of the RF tag T3 in the Y-axis direction, and the RF tag T3 is located at the center between the pair of radio wave shielding portions 730 (for example, the resin plate r). The signal strength tends to be low when the number of sheets is at the position of 3 to 5 sheets).

Therefore, from the viewpoint of increasing the received signal strength of the RF tag T2, the RF tag T3 is located between the pair of radio wave shielding portions 730 in the cross-sectional view shown in FIG. 32, and is among the pair of radio wave shielding portions 730. It is preferable to arrange it on the one side of the radio wave shielding portion 730. From the result of 0 to 2 resin plates r, it is preferable that the RF tag T3 is closer to the radio wave shielding portion 730 than the distance of two resin plates r. Further, the RF tag T3 is more preferably closer to the radio wave shielding portion 730 than the distance of one resin plate r from the result of 6 to 7 resin plates r. The RF tag T3 may be arranged, for example, about 1 mm inside (center side) from the radio wave shielding portion 730.

In FIG. 34, when the number of resin plates r is 3 to 5, detection is not possible, but this improves the antenna performance of the RF tag T3 or the strength of the radio wave radiated from the antenna a3. It is possible to detect by.

As described above, the attachment 30 of the tag reading system 800 has a pair of radio wave shielding portions 730 arranged so as to face each other in a cross-sectional view. Then, the RF tag T3 may be arranged between the pair of radio wave shielding portions 730 and on the radio wave shielding portion 730 side of one of the pair of radio wave shielding portions 730.

This increases the certainty that the antenna a3 detects the RF tag T2.

In the following, still another example of the arrangement of the RF tag T3 will be described with reference to FIGS. 35 to 37. FIG. 35 is a cross-sectional view showing a first example of the arrangement of the RF tag T3 according to this modification.

As shown in FIG. 35, the RF tag T3 may be arranged so as to be inclined at a predetermined angle with respect to the antenna a3 and the RF tag T2. The RF tag T3 may be arranged at an angle so that the polarization (for example, the X-axis direction) does not change (does not rotate) in a plan view, for example. The dashed line extending from the RF tag T3 indicates a virtual extension line passing through one end and the other end of the RF tag T3. Assuming that the angle formed by the virtual extension line and the antenna a3 is θ, the angle θ may be, for example, 45 ° or more and 135 ° or less. For example, the angle θ may be 90 ° (right angle). The angle θ is not limited to this, and when the supply unit 80 has the configuration shown in FIG. 31, the RF tag T3 is arranged so as not to contact each of the radio wave shielding portion 730 and the relay board 750, and the supply unit 80 is arranged. In the case of the configuration shown in FIG. 32, the angle may be such that it is arranged so as not to come into contact with the radio wave shielding portion 730. The angle θ may be an angle at which the virtual extension line and the virtual plane including the main surface on which the antenna pattern of the antenna a3 is formed intersect.

Further, when the RF tag T3 is arranged at an angle, the RF tag T3 may be arranged so as to straddle the central position between the pair of radio wave shielding portions 730, or may be arranged so as not to straddle.

As described above, the RF tag T3 is formed by a virtual extension line (broken line shown in FIG. 35) passing through one end and the other end of the main surface on which the antenna pattern m2 of the RF tag T3 is formed, and the antenna pattern m1 of the antenna a3. It may be arranged so as to intersect with the virtual plane including the main surface.

The RF tag T3 in the tag reading system 800 is an example of the first RF tag.

This increases the degree of freedom in the placement of the RF tag T3. Further, for example, when there are a plurality of types of attachments 30 having different lengths in the Z-axis direction, one RF tag T3 is prepared, the angle θ is adjusted, and the RF tag T3 is arranged to arrange the RF tag T3. It is possible to suppress the increase in the types of sizes of.

Further, the RF tag T3 may be arranged so that the virtual extension line and the virtual plane are orthogonal to each other.

This increases the degree of freedom in the placement of the RF tag T3.

FIG. 36 is a cross-sectional view showing a second example of the arrangement of the RF tag T3 according to this modified example. FIG. 37 is a cross-sectional view showing a third example of the arrangement of the RF tag T3 according to the present modification. 36 and 37 are cross-sectional views of the mounting system (tag reading system 800) in a plan view.

As shown in FIGS. 36 and 37, in a plan view, the radio wave shielding portion 730 has a frame shape and is provided so as to surround the RF tag T3. The radio wave shielding unit 730 has, for example, a rectangular frame shape, but is not limited thereto. As shown in FIG. 36, the RF tag T3 may be arranged so as to face the inner surface of one wall portion of the radio wave shielding portion 730. For example, the RF tag T3 may be arranged so as to face the inner surface of the wall portion on the longitudinal side in the plan view. Further, as shown in FIG. 37, the RF tag T3 may be arranged so as to be at a predetermined angle with the inner surface. For example, the RF tag T3 may be arranged so as to straddle the central position of the pair of wall portions in the longitudinal direction in a plan view.

Here, an arrangement method for arranging the RF tag T3 inside the attachment 30 will be described with reference to FIG. 38. FIG. 38 is a flowchart showing a method of arranging the RF tag T3 according to this modification. Initially, the RF tag T3 is not arranged on the attachment 30. Further, the step of preparing the attachment 30 to which the RF tag T3 is not arranged and the RF tag T3 corresponding to the attachment 30 is performed before the following step S401, but the illustration is omitted.

As shown in FIG. 38, the RF tag T3 is such that one end of the main surface on which the antenna pattern m1 is formed is on the antenna a3 side and the other end of the main surface is on the RF tag T2 side provided in the case 10. Is attached inside the attachment 30 (S401). Information about the attachment 30 may be stored in advance in the RF tag T3, or the information may be written by a reader / writer after being attached.

Next, the process proceeds to step S201 shown in FIG. 15, and the attachment 30 to which the RF tag T3 is attached is attached to the trolley 70 in step S401. The steps after step S201 are the same as those in FIG. 15, and the description thereof will be omitted. It can be said that step S402 is a method for manufacturing the attachment 30.

As described above, the tag placement method is a method of arranging the RF tag T3 attached to the attachment 30 (an example of the first production equipment unit), and one end of the main surface of the RF tag T3 is inside the attachment 30. It includes attaching the RF tag T3 so that it is on the antenna a3 side and the other end of the main surface is on the RF tag T2 side.

This makes it possible to reduce the number of antennas, cables, etc. provided inside the attachment 30.
