Description

  The present invention relates to a component supply apparatus.

Conventionally, a tape feeder is widely known as a component for supplying parts to a surface mounter. Such a tape feeder is provided with a feeding device or the like in the feeder main body, and a part is sent to a predetermined part supply position by pulling out a supply tape formed by holding the parts at regular intervals from the reel. This type of tape feeder is equipped with a manual locking device (a metal fitting 7 in the patent document) as described in the following patent document. It is fixed.
JP-A-6-239522

  Since the locking device found in the above documents can be released manually, the tape feeder can be easily removed from the surface mounter. The tape feeder itself must be replaced when the tape is exhausted, and it is of course necessary to have a structure that can be detached from the surface mounter. For example, in the following cases, removal is prohibited. There is a request.

  The mounting work of electronic components on the board does not always start immediately after the setup work is completed, but the setup work has been completed, but the mounting line has not yet started the mounting work. There may be. In such a case, if there is a shortage of electronic components on another active mounting line, the worker in charge of that mounting line has removed the feeder from the mounting machine on the standby mounting line to make up for the missing components. May end up.

  When the feeder line starts operation without the worker in charge of the mounting line in the standby state noticing that the feeder has been rented out, the electronic components of the removed feeder are removed from the surface mounter. An error occurs when the suction head tries to suck. Therefore, in the standby state as described above, there is a request for prohibiting the removal of the feeder.

  The present invention has been completed based on the above circumstances, and an object thereof is to provide a component supply device having a holding function for holding a feeder main body in a state in which it cannot be removed with respect to a base or a mounting member. And

  The present invention is a component supply device that is mounted directly on a base provided on a surface mounter or mounted on the base via an attachment member made of a member different from the base. A feeder body and a delivery device that has a delivery function of sending the part to a predetermined part supply position while pulling out a supply tape that holds the parts at regular intervals from the reel, and is fixed to the feeder body; An electric drive device that is fixed to the feeder main body and driven by an energization operation, and operates with the power of the driving device, the feeder main body cannot be removed from the base or the mounting member. And a holding device that performs a holding operation for holding in a state.

The following configuration is preferable as an embodiment of the present invention.
A component supply comprising: a sprocket that feeds the component to a predetermined component supply position while pulling out a supply tape that holds the component at regular intervals from the reel; and a feed motor that rotates the sprocket. And a switching mechanism for selectively executing a power transmission operation for transmitting the power of the feed motor to the holding device and an operation for cutting off the transmission, and the holding device holds the power by the power of the feed motor. It is configured to perform the operation. If it does in this way, it will become possible to operate a holding device using the power of a feed motor.

When the rotation direction of the feed motor that causes the component supply tape to be pulled out from the reel via the sprocket is defined as the normal rotation direction, the switching mechanism is configured such that when the feed motor rotates in the reverse rotation direction, While performing the power transmission operation and causing the holding device to perform the holding operation by the power of the feed motor, when the feed motor rotates in the forward rotation direction, the power transmission is interrupted, thereby The holding operation can be released. In this way, since a driving device dedicated to the holding device is not required, the number of parts can be reduced and the cost can be reduced.

The switching mechanism is a ratchet mechanism including a nail wheel that is rotated by the power of the feed motor and a claw that can be locked to the nail of the nail wheel, and when the feed motor rotates in the reverse rotation direction. When the claw is engaged with the claw of the claw wheel, the power of the feed motor is transmitted to the holding device via the claw wheel and the claw so that the holding device performs the holding operation. On the other hand, when the feed motor rotates in the forward direction, the transmission of the power is cut off by releasing the locking state between the claws on the claw of the claw wheel. . In this way, the switching mechanism can be realized with a relatively simple configuration (claw wheel and pawl). The switching mechanism can be realized by using a so-called clutch mechanism in addition to the above configuration.

In the case where a manual operation type fixing device that locks the feeder main body is provided on the base or the mounting member, the holding device is configured so that the lock by the fixing device cannot be released and the base Or the said feeder main body is hold | maintained in the state which cannot be removed with respect to the said attachment member.
The holding device includes a restricting member that is displaceable between a locking position for locking with the fixing device and a release position for releasing the locking, and when the feed motor rotates in the reverse rotation direction, The power of the motor acts on the restricting member via the hook wheel and the claw and displaces the restricting member from the release position to the locking position, so that the lock by the fixing device cannot be released.

  In this way, it is not necessary to provide the holding device with the mechanism itself for locking the feeder body to the base or the like, so that the configuration of the holding device can be simplified.

The holding device includes a regulating member that is displaceable between a locking position for locking with a receiving portion provided on the base or the mounting member and a release position for releasing the locking, and the feed motor When the motor rotates in the reverse rotation direction, the power of the feed motor acts on the restricting member via the pinion wheel and the claw, and the restricting member is displaced from the release position to the locking position. The feeder main body is held in a non-removable state with respect to the attachment member. Thus, if it is set as the structure which latches a control member directly with respect to a base or an attachment member, when hold | maintaining a feeder main body in the state which cannot be removed, the reliability of holding | maintenance becomes high.

The regulating member is displaced from the locking position to the releasing position or from the releasing position to the locking position by a sliding operation along the feeder body.

-The locking device is provided with a lock lever that can swing and displace in a seesaw shape around a hinge, and the lock lever can be locked to the base or the mounting member at one end. The other end of the lock lever is displaceable into a permissible position that allows the unlocking operation of the lock lever and a prohibition position that does not allow the unlocking operation of the lock lever by rotating around the axis. In addition to providing a pin, the holding device regulates the unlocking operation of the lock lever by displacing the regulation pin from the allowable position to the prohibited position, and with this, the base or the mounting member is Hold the feeder body in a non-removable state.

-While the feeder main body is provided with a receiving portion, the base or the mounting member is made of a metal that can be displaced between a locking position for locking the receiving portion and a release position for releasing the locking. The holding device is made of a magnet that displaces the restricting member from the release position to the locking position by a magnetic force when the holding device reaches a close position where the distance between the two is equal to or less than a predetermined distance. When the feed motor rotates in the reverse direction, the power of the feed motor acts on the suction member via the hook wheel and the claw to displace the suction member to the proximity position.

  According to the present invention, the component supply device can be held in a non-removable state with respect to the base or the mounting member. Moreover, since the holding device operates with an electric drive device, it cannot be released unless the electrical control is released. Therefore, it is possible to regulate the act of removing the component supply device that is contrary to the intention of the installation worker who installed the component supply device on the base or the like.

  Further, on one side of the carrier tape 81, engagement holes 81b penetrating vertically along the edge portion are provided at regular intervals. The component supply tape 80 is wound around and supported by a reel (not shown) at a rear position of a feeder F described below.

  The feeder main body 90 has a shape that is long in the left and right (Y-axis direction) in FIG. 5, and is provided with a tape passage 91 through which the component supply tape 80 passes through the upper surface wall on the right side shown in FIG. A guide member 93 is mounted on the upper wall of the feeder main body 90 so as to cover the tape passage 91, and is configured to guide the component supply tape 80 that passes through the tape passage 91.

  In the present embodiment, the component supply position O is set at a position near the tip of the tape passage 91, and the component supply tape 80 is sent to the front side of the device through the tape passage 91 by the delivery device 100 described below. The electronic component is supplied to the component supply position O.

  The delivery device 100 includes a sprocket 101, a feed motor 103, and a speed reduction device 105. The feed motor 103 is a so-called pulse motor (a motor that rotates in a predetermined step unit by giving a control pulse signal), and is arranged at a position slightly closer to the front of the feeder main body 90.

  The sprocket 101 is integrally formed with a driven gear 101A on its side surface, and is disposed at a position near the front of the feeder main body 90 and almost directly below the component supply position O. Locking teeth 102 are provided at equal intervals on the outer peripheral surface of the sprocket 101, and are configured to be engaged with the engagement holes 81b of the component supply tape 80 on the tape passage 91 (see FIG. 6). .

  The reduction gear 105 is composed of two reduction gears 106 and 107. Both gears 106 and 107 are two-stage gears in which a large gear and a small gear are integrally formed.

  The adjacent small gear and large gear mesh with each other, the leading reduction gear 106 meshes with the drive gear (motor gear) 103A of the feed motor 103, and the small gear of the trailing reduction gear 107 meshes with the driven gear 101A of the sprocket 101. Yes.

  Thus, the thing of this embodiment comprises the gear train which four gears, the motor gear 103A, the reduction gears 106 and 107, and the driven gear 101A transmit motive power (refer FIG. 6).

  Accordingly, when the feed motor 103 is energized, the power of the feed motor 103 is transmitted to the sprocket 101 via the gear train, and the sprocket 101 is rotated. As a result, the sprocket 101 rotates and pulls the component supply tape 80 forward, so that the component supply tape 80 is sent forward and the electronic components are supplied to the component supply position O at regular intervals. Yes.

The reverse direction (clockwise rotation direction) is defined as the reverse rotation direction.

  Returning to FIG. 5 and continuing the description, a control box 190 having a connector 195 at the front end is provided at the bottom of the feeder main body 90.

  The connector 195 of the control box 190 is electrically connected to a mating connector (not shown) on the feeder plate 70 side when the feeder main body 90 is attached to the feeder plate 70 by the fixing device 120 described below. . Accordingly, each feeder F is configured to receive power supply from the surface mounter body side through the connection of the connector.

Next, the fixing device (manual operation type fixing device) 120 will be described.
A lock lever 130 is attached to the lower wall of the feeder main body 90 via a bracket 121 having a hinge axis C.

  The lock lever 130 forms a lock protrusion 133 at the right end (front end) in FIG. 5, while a support pin 135 is provided at the right end (rear end) in FIG. The whole of the bracket 121 swings in a seesaw shape about the hinge axis C.

  The support pin 135 passes through an insertion hole provided in the lower surface wall 95 of the feeder main body 90, and the upper portion of the pin penetrates the lower surface wall 95 of the feeder main body 90 and protrudes toward the feeder main body side. As shown in FIG. 7, a flange 138 is provided on the upper portion of the pin, and the support pin 135 is prevented from coming off so as not to fall downward from the lower surface wall 95 of the feeder main body 90.

  A lock spring 139 is attached to the outer periphery of the support pin 135 and pushes the rear end of the lock lever 130 downward.

  Thereby, the front end side of the lock lever 130 is pushed to the feeder plate 70 side, and the lock projection 133 is locked to the receiving portion 75 of the feeder plate 70. Thus, the feeder main body 90 is configured to be locked to the feeder plate 70.

  As shown in FIG. 7, a release operation wire W is hung on the rear end portion of the lock lever 130. On the other hand, a release lever 140 is provided at a position near the rear end on the upper side of the feeder F, and the other end of the wire W is connected to the release lever 140 (see FIG. 5).

  From the above, when the rear end of the release lever 140 is pushed downward, the rear end of the lock lever 130 is pulled upward via the wire W as shown in FIG.

  Then, as a result of the lock lever 130 rotating about the hinge axis C in the direction of the arrow R shown in FIG. 7, the lock projection 133 of the lock lever 130 and the receiving portion 75 of the feeder plate 70 are unlocked (unlocked). ), The feeder main body 90 can be removed from the feeder plate 70 (see FIG. 8).

  The feeder F of the present embodiment is configured to be held in a state where the lock cannot be released by electrical control. Hereinafter, a specific configuration for realizing this will be described.

  As shown in FIG. 9, the feeder F is provided with a ratchet mechanism 150 including a claw wheel (so-called ratchet) 160 having claws 165 formed on the outer periphery at equal intervals, and a locking member 170.

  The claw wheel 160 is disposed near the center of the feeder main body 90 and above the motor gear 103A. The gear wheel 160 is integrally provided with a gear 161 on the side surface, and the gear 161 of the gear wheel 160 is engaged with the motor gear 103A (see FIG. 9).

  On the other hand, the locking member 170 is pivotally supported by a hinge C <b> 1 at a position below the claw wheel 160 in the feeder main body 90. The locking member 170 has a long shape in one direction, and a claw (so-called pole) 171 that can be locked to the claw 165 of the claw wheel 160 is formed at the tip (one end).

  Further, the rear end (other end) 175 of the locking member 170 is jointed to the front end of a regulating member 180 described below. The regulating member 180 has a bar shape that is long in one direction, and is attached to the lower portion of the feeder main body 90 in a horizontal direction with the axis in the horizontal direction. The restriction member 180 is supported by a slide guide 185, and is configured to be able to perform only a sliding operation in the horizontal direction.

  When the pinion wheel 160 is in a stopped state, the force is balanced so that the locking member 170 is substantially located at the neutral position shown in FIG. That is, a spring member 177 is provided at the rear end of the locking member 170, and the spring force of the spring member 177 is determined in consideration of the weight of the locking member 170 and the like. The self-weight and the spring force are just balanced, and the locking member 170 is almost stationary at the position shown in FIG.

  On the other hand, as already explained, the support pin 135 is fixedly attached to the lock lever 130. In the present embodiment, a restriction hole 137 that penetrates the pin 135 horizontally is formed in the upper part of the support pin 135 that penetrates the lower wall of the feeder main body 90.

  When the lock lever 130 is in the locked state, the support pin 135 is in the height position shown in FIGS. 7 and 9. At this time, the restriction hole 137 and the restriction member 180 of the support pin 135 are exactly the same height position. Thus, the restriction member 180 can be received in the restriction hole 137 from the front.

  The operation of the above apparatus will be described. First, when the feed motor 103 is rotated in the forward rotation direction, power is transmitted by the meshing of the gears, and the claw wheel 160 is rotated in the direction of arrow B (clockwise direction) shown in FIG. Then, the portion of the claw 171 provided at the tip of the locking member 170 gets on the outer peripheral portion of the ratchet wheel 160, so that the locking member 170 swings around the hinge C1.

  As a result, the regulating member 180 is pulled to the front side of the apparatus via the locking member 170 and is separated from the support pin 135 (FIG. 10). At this time, the spring member 177 is displaced so as to shorten the overall length as compared with the neutral state shown in FIG.

  On the other hand, when the feed motor 103 is rotated in the reverse rotation direction from the state shown in FIG. 9 or the state shown in FIG. 10, the power is transmitted by the meshing of the gears, and the claw wheel 160 is moved in the direction indicated by the arrow C (reverse to FIG. 9). Rotate clockwise).

  Then, as shown in FIG. 11, the portion of the claw 171 provided at the tip of the locking member 170 is engaged with the claw 165 provided at the outer peripheral portion of the claw wheel 160, and as a result, the claw 171 at the tip is The latch member 170 is pushed forward by the claw 165 of the claw wheel 160, and the locking member 170 swings about the hinge C1.

  As a result, the regulating member 180 is pushed to the rear of the device corresponding to the left side of FIG. 11 via the locking member 170, enters the regulating hole 137 of the support pin 135, and penetrates the regulating hole 137 to the left and right.

  As described above, when the regulating member 180 passes through the regulating hole 137 of the support pin 135 to the left and right, the support pin 135 cannot move upward from the position shown in FIG.

  Therefore, the lock lever 130 cannot be rotated in the unlocking direction. Even if the operator operates the release lever 140 shown in FIG. 4, the lock (the lock projection 133 of the lock lever 130 and the feeder The engagement of the plate 70 with the receiving portion 75 is not released.

  Thus, when the feeder motor 103 rotates the feed motor 103 in the reverse rotation direction, the power of the feed motor 103 is transmitted to the regulating member 180 by the action of the ratchet mechanism 150 (corresponding to the power transmission operation of the present invention). 9 and FIG. 10, the restricting member 180 in the release position (the position where the locking with respect to the restriction hole 137 is released) is displaced to the locking position (the position where the restriction hole 137 is locked) shown in FIG. Let As a result, the fixing device 120 cannot be unlocked, and as a result, the feeder F can be held in a state where it cannot be removed from the feeder plate 70.

  Note that when in the holding state, the spring member 177 is displaced so as to lengthen the entire length as compared with the neutral state (the state shown in FIG. 9), so that the energization to the feed motor 103 is cut off. When the torque is not generated in the feed motor 103, the spring member 177 pulls the regulating member 180 to the right side of FIG. 11 corresponding to the front side of the apparatus via the locking member 170. As a result, the regulating member 180 regulates the support pin 135. Remove from hole 137.

  As a result, the position restriction is released and the support pin 135 can move up and down, and if the release lever 140 is operated from this state, the lock by the lock lever 130 can be released.

  Further, according to the configuration described above, “the holding device unlocks the locking position (the position shown in FIG. 11) locked with the fixing device (here, the support pin 135) and the locking. A regulating member 180 that is displaceable to a release position (the position shown in FIGS. 9 and 10) is provided, and when the feed motor 103 rotates in the reverse rotation direction, the power of the feed motor 103 is transmitted to the claw wheel 160 and the pawl. The fixing device is operated by acting on the restriction member 180 via 171 and displacing the restriction member 180 from the release position (position shown in FIGS. 9 and 10) to the locking position (position shown in FIG. 11). (Here, the lock by the lock lever 130 cannot be released ").

  In this embodiment, a regulating member 180, a spring member (a member having a function of biasing the regulating member 180 to the release position) 177, a slide guide (a guide between the regulation member 180 and the locking position and the release position). The member having a guide function to be displaced 185) constitutes the holding device of the present invention.

3. Next, the electrical configuration of the surface mounter 10 will be described with reference to FIG.

Data for controlling the transport system such as 20 is stored.

  The servo system control unit 215 drives the various motors in accordance with the mounting program together with the arithmetic processing unit 211, and various motors are electrically connected to the servo system control unit 215.

  Further, the part recognition camera 17 is electrically connected to the image processing unit 216 so that an image pickup signal output from the camera 17 is captured. The image processing unit 216 performs component image analysis and board image analysis based on the captured image signal.

  The controller 210 is provided with a display / operation unit 230, which is configured to be able to give various operations and commands by external operations.

  The input / output unit 217 is a so-called interface, and is configured to receive detection signals output from various sensors provided in the main body of the surface mounter 10 in addition to transmitting and receiving control signals to and from the feeder F. Has been.

4). Effects of this embodiment When the board P to be produced is switched to one of a different type, the mounted electronic components will of course also change, and it is necessary to perform a setup operation to replace the feeder F. For this purpose, the release lever 140 is operated to remove the used feeder F from the carriage D, and instead, a new feeder F is attached to the carriage D in the following manner.

  In order to attach a new feeder F, first, the feeder F may be positioned at a predetermined position on the feeder plate 70, and then slide on the feeder plate 70 toward the front of the apparatus.

  When this is done, the lock projection 133 of the lock lever 130 provided on the feeder F can be locked to the receiving portion 75 of the feeder plate 70, and the feeder F can be fixed (locked) on the carriage D.

  For example, when the production of a new substrate P is not started immediately after the setup work is completed and there is a waiting time until the production starts, the display / operation unit 230 provided on the main body side of the surface mounter 10 is changed. The feeder F can be held in a state where it cannot be removed from the carriage D by operating and giving a command to rotate the feed motor 103 in the reverse rotation direction to each feeder F that has been set up.

  This is because when the feed motor 103 rotates in the reverse rotation direction, the claw wheel 160 provided on the feeder F rotates in the direction of arrow C (counterclockwise direction) shown in FIG.

  Then, as shown in FIG. 11, the portion of the claw 171 provided at the tip of the locking member 170 is engaged with the claw 165 provided at the outer peripheral portion of the claw wheel 160, and as a result, the claw 171 at the tip is The latch member 170 is pushed forward by the claw 165 of the claw wheel 160, and the locking member 170 swings about the hinge C1.

  As a result, the regulating member 180 is pushed rearward of the device via the locking member 170, enters the regulating hole 137 of the support pin 135, and penetrates the regulating hole 137 to the left and right. As described above, when the regulating member 180 passes through the regulating hole 137 of the support pin 135 to the left and right, the support pin 135 cannot move upward from the position shown in FIG.

  In this state, since the lock lever 130 cannot be rotated in the unlocking direction, the feeder F is held in a state in which it cannot be removed from the carriage D.

  Once the holding state is reached, the holding state is not released unless the electric control is released. Therefore, the feeder F is removed from the cart D against the will of the operator who has replaced the feeder F. The state immediately after the end of the setup can be maintained during the waiting time.

  In addition, when the production of the substrate P is started after the standby time has elapsed, the feed motor 103 of the feeder F rotates in the forward rotation direction, and the engagement between the hook wheel 160 and the engagement member 170 is automatically released. As a result, the power of the feed motor 103 does not act on the regulating member 180.

  Then, as a result of the spring member 177 pulling the restricting member 180 forward, the restricting member 180 is disengaged from the restricting hole 137 of the support pin 135, whereby the holding of the feeder F is automatically released. Therefore, after that, when the parts run out, the feeder F can be easily detached from the carriage D by operating the release lever 140.

  In this embodiment, the feed motor 103 also serves as a drive device for a mechanism that can hold the locked state in a state where it cannot be released. With such a configuration, the number of parts can be reduced and the cost can be reduced as compared with the case where the drive device is provided exclusively for the drive device.

  When the feed motor 103 is rotated in the reverse rotation direction, it is preferable to perform control to reduce the amount of current supplied to the feed motor 103 after a predetermined time has elapsed from the start of rotation or after a predetermined amount of rotation. This is because when the feed motor 103 is rotated in the reverse direction, the hook wheel 160 and the locking member 170 are eventually locked (FIG. 11). Then, the feed motor 103 can no longer rotate and stops rotating at that position. Then, after the stop, a torque sufficient to maintain the state of FIG. 11 (a force for pushing the regulating member 180 backward against the biasing force of the spring member 177) can be applied via the feed motor 103. This is because the state where the lock cannot be released can be maintained.

<Embodiment 2>
Next, Embodiment 2 of the present invention will be described with reference to FIG.
The second embodiment differs from the first embodiment in the configuration of the fixing device that locks the feeder F to the carriage D and the mechanism that can be held in a state where the lock cannot be released. The configuration is the same as that of the first embodiment.

The fixing device 310 according to the second embodiment will be described.
A lock lever 320 is attached to a position near the front of the feeder main body 300 via a hinge C2. The lock lever 320 is provided with a lock pin 330 at the bottom, and the feeder main body 300 is fixed to the carriage D when the lock pin 330 is engaged with the tip of the feeder plate 70 of the carriage D.

  Reference numeral 340 shown in FIG. 13 is a release lever. The release lever 340 is jointed to the lock lever 320 via three connection links 341, 342, and 343. When the release lever 340 is operated in the direction of arrow D shown in FIG. 13, the connection link 343 is moved horizontally. Slide to pull the lock lever 320 backward.

  Accordingly, as a result of the lock lever 320 rotating around the hinge C2, the lock pin 330 below the lever is separated from the feeder plate 70, and the lock by the lock lever 320 is released.

  Next, a mechanism capable of holding the lock by the fixing device 310 in a state where it cannot be released will be described. As shown in FIG. 13, a rack gear 410 having a regulating member 420 attached to the lower part is attached to the feeder main body 300 so as to be movable up and down. The rack gear 410 is biased upward by a spring 430 and is always set so that the lower-end regulating member 420 is separated from the connection link 343.

  In addition, a first bevel gear 380 is disposed at a position near the front of the feeder main body 300 and to the right of the rack gear 410, and further, a claw wheel (so-called ratchet) 360 is coaxial with the first bevel gear 380. Is arranged.

  The claw wheel 360 has a configuration in which claws 365 are formed on the outer periphery at equal intervals and is rotated by receiving the power of the feed motor 103. In FIG. 13, the feed motor 103 is omitted, but the same motor as that of the first embodiment is mounted on the feeder main body 300.

  Three claws (so-called poles) 370 are provided at equal intervals on the inner peripheral side of the first bevel gear 380. These three claws 370 constitute a ratchet mechanism 350 together with a claw wheel 360.

  That is, when the feed motor 103 rotates in the forward direction, the claw wheel 360 rotates in the clockwise direction in FIG. Then, the claw 370 rides on the outer peripheral portion (claw) of the rotated claw wheel 360, and no force for rotating the first bevel gear 380 is generated.

  On the other hand, when the feed motor 103 rotates in the reverse rotation direction, the claw wheel 360 rotates in the counterclockwise direction in FIG. Then, the claw 370 is locked to the outer peripheral portion (claw) of the rotating claw wheel 360. As a result, the power of the feed motor 103 is transmitted to the first bevel gear 380 (power transmission operation), and the first bevel gear 380 is rotated in the direction of arrow F shown in FIG.

  As shown in FIG. 13, a second bevel gear 390 is installed on the outer periphery of the first bevel gear 380, and the pinion gear 400 meshing with the rack gear 410 and the second bevel gear 390 are connected by a shaft. is there.

  From the above, when the first bevel gear 380 rotates in the direction of arrow F shown in FIG. 13, the power is transmitted to the rack gear 410 via the second bevel gear 390 → pinion gear 400. As a result, the rack gear 410 slides downward while resisting the biasing force of the spring 430.

  As a result, the restriction member 420 provided in the lower portion of the rack gear 410 penetrates the restriction hole 343A provided in the connection link 343 vertically. In other words, the restriction member 420 is displaced downward from the release position (position where the restriction hole 343A is unlocked) shown in FIG. 13 and reaches the locking position (position where the restriction hole 343A is locked). As a result, the connecting link 343 cannot move in the left-right direction from the position shown in FIG.

  From the above, the lock lever 320 cannot be unlocked, and the feeder F is held in a state where it cannot be removed from the carriage D.

  Moreover, the code | symbol RS shown in FIG. 13 is a limit switch. The limit switch RS is responsible for the position detection function of the rack gear 410, and outputs a detection signal when the lower end of the rack gear 410 hits the limit switch RS.

  In this embodiment, the first bevel gear 380, the second bevel gear 390, the pinion gear 400, the rack gear 410, the spring 430, and the restricting member 420 constitute the holding device of the present invention.

<Embodiment 3>
Next, Embodiment 3 of the present invention will be described with reference to FIG.
In the configuration of the first embodiment, the feeder F cannot be removed from the carriage D by disabling the lock lever 130 of the fixing device 120. Specifically, the above-described configuration is realized by locking the regulating member 180 to the support pin 135 of the lock lever 130.

  On the other hand, the thing of Embodiment 3 prevents the feeder F from being removed from the trolley D by locking the regulating member 180 of the feeder F to the feeder plate 70 of the trolley D.

  In this embodiment, the power of the feed motor 103 is transmitted to the restricting member 180 using the ratchet mechanism 150 including the claw wheel 160 and the locking member 170, and the feed motor 103 rotates in the reverse direction. Only when it rotates in the direction, the hook wheel 160 and the locking member 170 are locked.

  Then, as shown in FIG. 14, as a result of the locking member 170 rotating about the hinge and pushing the regulating member 180 downward, the locking member 170 is vertically locked through the regulating hole 77 provided in the feeder plate 70. It has become.

  Thus, if it is set as the structure which latches the regulating member 180 directly with respect to the feeder plate 70, when hold | maintaining the feeder F in the state which cannot be removed, the reliability of holding | maintenance becomes high.

  Note that, according to the configuration described above, “the holding device is locked to a receiving portion (here, the restriction hole 77) provided on the base or the mounting member (here, the feeder plate 70). And a restricting member displaceable at a locking position (here, the position of FIG. 14A) and a release position where the locking is released (here, the position of FIG. 14B), When the feed motor rotates in the reverse rotation direction, the power of the feed motor acts on the restricting member via the pinion wheel and the claw and moves the restricting member to the release position (here, the position shown in FIG. 14B). ) To the locking position (here, the position shown in FIG. 14A), the feeder body cannot be removed from the base or the mounting member (here, the feeder freight 70). Is held in a state " ing.

<Embodiment 4>
Next, a fourth embodiment of the present invention will be described with reference to FIGS.
In the fourth embodiment, as in the first embodiment, the support pin 450 provided at the rear end of the lock lever 130 cannot be moved upward from the position of FIG. 15 so that the lock is not released. I have to.

  The structure of the fourth embodiment is different from the structure of the first embodiment in that the support pins 450 cannot be moved upward in the apparatus, and the support pins 450 are arranged with respect to the linear grooves 480 provided in the feeder main body 90. It is made impossible to move upward by rotating it to a position where it becomes inconsistent.

  More specifically, as shown in FIG. 16, the feeder main body 90 is provided with an accommodating portion 97 provided with a partition wall 460 at the lower portion. The partition wall 460 has a circular shape, and a communication hole 470 that is slightly larger than the diameter of the support pin 450 is provided at the center thereof. A straight groove 480 is formed in the partition wall 460 so as to cross the connection hole 470.

  On the other hand, the support pin 450 is attached to the rear portion of the lock lever 130 through a bearing 457 so as to be rotatable. As in the first embodiment, the tip of the pin penetrates the lower surface wall 95 of the feeder main body 90 up and down, and the penetrated upper end portion is inserted into the communication hole 470 of the partition wall 460.

  In addition, a protruding portion 455 having a linear shape following the shape of the linear groove 480 is formed at the upper end portion of the support pin 450, and the locked state (the lock lever 130 is the feeder plate 70) shown in FIG. In this state, the overhanging portion 455 is set to be positioned below the partition wall 460.

  From the above, in the locked state shown in FIG. 16A, when the overhanging portion 455 of the support pin 450 is in an orthogonal state with respect to the linear groove 480 of the communication hole 470, the overhanging portion 455 is The support pin 450 cannot pass through the straight groove 480 and cannot move upward from the position (a) shown in FIG. That is, the lock cannot be released.

  On the other hand, the support pin 450 is rotated by 90 degrees from the position of FIG. 16A, and as shown in FIG. 16B, the protruding portion 455 of the support pin 450 with respect to the linear groove 480 of the communication hole 470. Are aligned in the same direction, the overhanging portion 455 can pass through the linear groove 480.

  As a result, the support pin 450 can be moved upward from the position (a) shown in FIG. 16, and the lock can be released as shown in FIG. 16 (b).

  Thus, the thing of Embodiment 4 has created the state which cannot be unlocked, and the state which can be unlocked by rotating the support pin 450 centering on an axis | shaft.

  The support pin 450 corresponds to the “regulation pin” of the present invention, and the position (rotation) of the support pin 450 shown in FIG. 16A where the overhanging portion 455 is not aligned with the linear groove 480. The position of the support pin 450 shown in FIG. 16B where the overhanging portion 455 is aligned with the linear groove 480 (position in the rotation direction) corresponds to the prohibition position of the present invention. This corresponds to the allowable position.

  And the thing of Embodiment 4 also uses reverse rotation operation | movement of the feed motor 103 to switch from the state which can be unlocked to the state which cannot be unlocked similarly to Embodiment 1-3. Hereinafter, a mechanism for transmitting the power of the feed motor 103 to the support pins 450 will be described.

  As shown in FIG. 15, a fourth bevel gear 520 is fixed to the support pin 450 via a shaft 530, and a third bevel gear 510 is engaged with the fourth bevel gear 520.

  The feeder main body 90 is provided with the ratchet mechanism 150, the first bevel gear 380, and the second bevel gear 390 that are applied in the second embodiment, and the second bevel gear 390 and the third bevel gear 510 are connected by a shaft. It is connected.

  With such a configuration, when the feed motor 103 rotates in the reverse rotation direction, the power of the feed motor 103 is changed from the ratchet mechanism 150 → the first bevel gear 380 → the second bevel gear 390 → the third bevel gear 510 → the fourth bevel gear. It is transmitted to the support pin 450 via 520. Thereby, a force around the axis (force in the rotation direction) acts on the support pin 450.

  Therefore, the feeder F can be held in a state where it cannot be removed from the carriage D if it is set so that the rotation of the support pin 450 is stopped when the overhanging portion 455 is in the inconsistent state.

  According to the above configuration, in the present invention, “the fixing device is provided with the lock lever 130 that can be oscillated and displaced in a seesaw shape around the hinge, and the lock lever 130 has the base or A locking protrusion 133 that can be locked to the attachment member (here, the feeder plate 70) is formed, and at the other end, an allowable position that allows the unlocking operation of the locking lever 130 by a rotational operation around the axis. A restricting pin (here, a support pin 450) that is displaceable to a prohibited position that does not allow the unlocking operation of the lock lever 130 is provided, and the holding device (here, each of the bevel gears 380, 390, 510) is provided. 520) displaces the restricting pin (here, the support pin 450) from the allowable position to the forbidden position, thereby the lock lever 130. Regulating the unlocking operation, (in this case, the feeder plate 70) which with a said base or said mounting member said retaining disabled state and remove the feeder body "is realized for.

<Embodiment 5>
Next, Embodiment 5 of the present invention will be described with reference to FIG.
In the third embodiment, the feeder plate 70 is locked with the regulating member 180 of the feeder F so that the feeder F cannot be removed from the carriage D.

  On the other hand, the configuration of the fifth embodiment is reversed from that of the third embodiment, and a regulating member 610 is provided on the feeder plate 70, and the regulating member 610 is provided in the concave portion 670 of the feeder main body 90. The feeder F cannot be removed from the carriage D by being locked.

  Specifically, the feeder main body 90 is provided with a claw wheel 160 and a locking member 170 as in the case of the third embodiment. As shown in FIG. 17, a magnet suction member 660 is fixed to one end of the locking member 170, and a recess 670 is provided below the suction member 660.

  On the other hand, a regulating member 610 made of a metal rod is attached to the feeder plate 70 in a state in which it can move up and down. The restricting member 610 receives a downward biasing force via the coil spring 620, and is always set so that the tip is positioned below the upper surface of the feeder plate 70.

  When the feed motor 103 rotates in the reverse rotation direction, the claw wheel 160 rotates in the G arrow direction (counterclockwise direction) shown in FIG. Then, the portion of the claw 171 provided at the tip of the locking member 170 is engaged with the claw 165 provided at the outer peripheral portion of the claw wheel 160, so that the claw 171 at the tip is moved by the claw 165 of the claw wheel 160. The locking member 170 swings about the hinge C1.

  As a result, the suction member 660 descends and reaches a close position (position shown in FIG. 17, which is close to the regulating member 610 made of a metal rod) that is substantially in close contact with the ceiling portion 671 of the recess 670. Then, the restriction member 610 made of a metal rod is pulled by the suction member 660 and displaced upward by the action of magnetic force. As a result, the tip of the regulating member 610 enters the recess 670 of the feeder main body 90.

  Thus, when the regulating member 610 is fitted into the recess 670, the feeder F is fixed and cannot be removed from the carriage D.

  Note that, according to the above configuration, “the feeder main body is provided with a receiving portion (here, the recess 670), while the base or the mounting member (here, the feeder plate 70) is provided with the receiving portion (here, Then, the metal which can be displaced between the locking position (position (a) in FIG. 17) for locking the recess 670) and the release position (position (b) in FIG. 17) for releasing the locking. In the case where the made restricting member 610 is provided, the holding device moves the restricting member 610 to the release position (FIG. ) To the locking position (position (a) in FIG. 17). When the feed motor 103 rotates in the reverse direction, the power of the feed motor 103 is changed to the claw wheel 160 and Nail 171 Acts on the suction member 660 by reason to displace the suction member 660 to the near position "is realized.

  (1) In any of the first to fifth embodiments, the example in which the feeder F is attached to the component supply unit 30 via the carriage D has been shown. However, the feeder F may be directly attached to the component supply unit 30 without passing the carriage D. Of course it is possible.

  (2) In any of the first to fifth embodiments, an example in which the driving device of the mechanism that can hold the feeder F in a state where it cannot be removed from the carriage D is used by the feed motor 103 is used. However, the driving device is not necessarily used. For example, it is possible to apply a dedicated motor separately from the feed motor 103, for example. The drive device does not necessarily need to be a motor, and other devices such as a solenoid switch (a device that moves the plunger shaft forward and backward by energizing the coil) may be used.

  (3) In the first embodiment, the ratchet mechanism 150 is illustrated as an example of the switching mechanism of the present invention. When the feed motor 103 rotates in the reverse direction, the power of the feed motor 103 is regulated via the ratchet mechanism 150. (The power transmission operation), and the lock member 130 cannot be unlocked by causing the restriction member 180 to enter the restriction hole 137 of the support pin 135.

  In addition, for example, the switching mechanism of the present invention may be configured by a clutch mechanism that can control transmission / cutoff of power by an energization operation, and transmit the power of the feed motor 103 to the regulating member 180 only during energization. For example, the forward rotation operation of the feed motor 103 can be used to hold the lock lever 130 in a state where the lock cannot be released. Even when the lock lever 130 cannot be unlocked by using the forward rotation operation of the feed motor 103, the lock lever 130 can be unlocked by turning off the power to the clutch mechanism. The same effect as that of can be expected.
