[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a parts supply device, and more specifically, feeds parts to a succeeding apparatus by sequentially taking out the parts packed in a row in a cylindrical container one by one and placing them at a parts picking position by the succeeding apparatus. The present invention relates to a component supply device.
Such a component supply device is arranged next to a mounting device such as a chip mounter, and when the electronic device such as an IC or a connector is mounted on the surface of the printed board by the mounting device, the mounting head of the mounting device or the like is mounted on the electronic component. It is particularly suitable for sequentially feeding and supplying electronic components to a predetermined position for taking out the components.
[0002]
[Prior art]
If a component to be mounted, also called a workpiece, has a shape conforming to a general standard and is mounted on a tape, the component is supplied using a standard tape mounter or the like.
On the other hand, it is often when the workpiece is not a standard product, but when the workpiece is contained in a cylindrical container called a stick, the workpiece is packed in a row of sticks with stoppers at both ends. Therefore, there is a need for a component supply device that removes the workpiece from the stick and sends it to the component removal position by the mounter.
[0003]
Conventionally, such a component supply apparatus has been provided with a stick storage unit (storage mechanism) for storing the stick with the workpieces removed by removing the plugs at both ends, and for feeding the workpiece to the component removal position. A workpiece feeding unit (feeding mechanism) is provided. Furthermore, a rail part (guide mechanism) is interposed between the stick storage part and the work feeding part, and when the work is sent out from the stick stored in the stick storage part, the work is fed in order. Guided to the department.
[0004]
Specific examples of the component supply apparatus are shown in FIGS. 7 to 10. FIG. 7 shows the overall mechanism, (a) is a plan view, and (b) is a side view. FIG. 8 is a block diagram of the control unit and the drive unit, FIG. 9 is an operation diagram of the stick discharge unit, and FIG. 10 is an operation diagram of the work feeding unit.
In this component supply device, a base plate 2 is fixed on a base 1 of a mounter 4, and a stick storage unit 10, a rail unit 20, and a workpiece feed from the rear on the right side in the figure to the front on the left side in the figure. The parts 30 are arranged and connected in a straight line while being inclined downward to the left in the figure, and these mechanism parts are supported by the support columns 3 on the base plate 2 to maintain the state.
[0005]
In the stick storage unit 10 (see FIG. 7), a front plate 16 and a rear plate 17 opposed to each other in the front and rear directions are connected by a side plate 15, and two guides 16a and a rear plate are provided vertically on the opposed surface of the front plate 16. The two ends of the stick 5 are inserted between the two guides 17a that are vertically provided on the opposing surface 17 so as to be loosely stored. On the opposite surface of the front plate 16, a stick receiver 18 whose vertical position can be adjusted is provided at the lower end of the guide 16 a so as to support one end of the stick 5 and penetrate the lower end of the guide 16 a on the rear plate 17. A hole is perforated, and the escaper 14 protrudes from the hole to support the other end of the stick 5. The front plate 16, the guide 16a, the rear plate 17, and the guide 17a are long enough to accommodate a plurality of sticks 5 stacked thereon.
[0006]
In addition to the escaper 14 that receives the lowermost stick 5, a stick discharge mechanism (discharge mechanism) that includes a pin-shaped escaper 13 disposed immediately above the rear plate 17 of the stick storage unit 10 is incorporated. (See FIG. 9). That is, the escaper 13 is driven by the air cylinder 11 attached to the non-opposing surface side of the rear plate 17 to advance and retreat through the perforation of the rear plate 17, and the second stick 5 from the bottom when moving forward. The tip is inserted into the end, and is removed when retreating. Further, the escaper 14 is driven by the air cylinder 12 attached to the non-opposing surface side of the rear plate 17 so as to advance and retreat through the perforation of the rear plate 17, and at the end of the lowermost stick 5 during the advancement. In response, the stick 5 comes off when retreating. The escapers 13 and 14 can also be adjusted in the vertical position according to the height of the stick 5.
[0007]
The rail portion 20 (see FIG. 7) is provided with a rail cover 24a that covers the groove on the rail body 24 that has a groove-shaped engraved groove on the upper surface. This is a rail lumen 24b (guide path). The rail main body 24 and the rail inner cavity 24b extend to the workpiece feeding unit 30, but do not extend to the part picking position by the mounter 4. The rear end of the rail body 24 is fixed in contact with the front plate 16, and the workpieces 6 fed from the lowermost stick 5 in the stick storage unit 10 through the through holes of the front plate 16 are aligned in a row. In this state, it passes through the rail lumen 24b in order and is guided from its rear end to its front end.
[0008]
The rail lumen 24b of the rail portion 20 is provided with a photoelectric work sensor 23 (see FIG. 7) for detecting the presence or absence of the work 6 passing near the rear end thereof based on reflected light or the like (see FIG. 7). An air cylinder 21 and an air cylinder 22 (standby mechanism) with a work stopper are also provided near the front end thereof. The air cylinder 22 is arranged corresponding to the leading work 6 in the rail lumen 24b, that is, the work 6 at the front end, and the air cylinder 21 is arranged corresponding to the next work 6, ie, the second work 6 from the front end. In both cases, when the rod is extended, the stopper presses and stops the workpiece 6 below from the open portion or through hole of the rail cover 24a (see FIG. 10).
[0009]
The workpiece feeding unit 30 (see FIG. 7) is provided with a movable table 33 and a cam 34 (leveling mechanism) for receiving the workpiece 6 sliding down from the front end of the rail lumen 24b. The movable table 33 is formed so that the upper surface can carry one workpiece 6, and is provided with a cam follower that can roll on the inclined surface of the cam 34, and is rotatably supported by the slider 32. Then, when the slider 32 is driven by the air cylinder 31 and the movable base 33 moves rearward thereby, the cam follower rides along the inclined surface of the cam 34, the movable base 33 is tilted, and the workpiece mounting portion becomes the rail lumen 24b. (See FIG. 10 (a)). Further, when the movable base 33 moves forward, it is supported horizontally away from the cam 34, and the workpiece mounting portion comes to the part removal position by the mounter 4 (see FIG. 10 (f)).
[0010]
The controller 40 (see FIG. 8) is composed of a programmable sequencer or microprocessor, receives a component feeding instruction A from the mounter 4, inputs a component detection signal E of the work sensor 23, and outputs a stick discharge output B as an electromagnetic valve. 42, the component feed output C is sent to the solenoid valve 43, and the slider operation output D is sent to the solenoid valve 44. Although these outputs B, C, and D are normally OFF, when the stick discharge output B is turned ON, the compressed air supply state to the stick discharge mechanism is switched by the electromagnetic valve 42, and the rod of the air cylinder 11 moves forward. The rod of the air cylinder 12 moves backward. When the component feed output C is turned ON, the compressed air supply state to the standby mechanism is switched by the solenoid valve 43, the rod of the air cylinder 21 moves forward, and the rod of the air cylinder 22 moves backward. Further, when the slider operation output D is turned ON, the rod of the air cylinder 31 moves forward by switching the electromagnetic valve 44. As such, air tube piping and the like are provided.
[0011]
Then, when the component detection signal E of the work sensor 23 changes from the state with a work to the state without a work, it is detected based on this that the lowermost stick 5 has become empty. Further, according to the detection result, the stick discharge output B is turned from OFF to ON, and is returned to OFF after a predetermined period. Then, from the state in which the lowermost stick 5 is supported by the escaper 14 corresponding to the initial OFF (see FIG. 9A), the escaper 13 moves forward in response to the next ON transition and 2 from below. While the second stick 5 is supported, the escaper 14 moves backward and the bottom stick 5 is removed and falls (see FIG. 9B). Thereafter, in response to the return to OFF, the escaper 13 moves backward and the stick 5 thereover and the stick 5 overlying it are likely to fall, but the advanced escaper 14 immediately receives the stick 5 from below. Support (see FIG. 9C).
[0012]
In this way, when all the sticks 5 stored in the stick storage unit 10 are sent out and are emptied, they fall downward from between the side plates 15 and are sequentially discharged. Then, each stick 5 above it will roll down in turn.
Then, when the work 6 slides down from the stick 5 at the bottom and is sent out in order from the front end, and passes through the through hole of the front plate 16 and further through the rail lumen 24b, it reaches the front of the work feeding unit 30. It is stopped by a stopper at the tip of the rod of the cylinder 22 and is made to wait there.
[0013]
In this state (see FIG. 10A), when the controller 40 receives a component feeding instruction A from the mounter 4, first, the component feeding output C is turned from OFF to ON, and the rod of the air cylinder 22 moves backward to move the air cylinder. The rod 21 moves forward, and only the foremost workpiece 6 in the rail lumen 24b is transferred to the movable base 33 (see FIG. 10B). Then, when the component feed output C is turned OFF, the subsequent workpiece 6 advances one by one in accordance with the rod retreat of the air cylinder 21 and is made to wait there by the rod advance of the air cylinder 22 (FIG. 10 (c)). )reference).
[0014]
Next, the slider operation output D is turned from OFF to ON, and is returned to OFF after a predetermined period. Then, the movable table 33 moves forward away from the rail portion 20 (see FIG. 10D), is also separated from the cam 34 and becomes horizontal (see FIG. 10E), and further advances to the component removal position by the mounter 4. Stop at. Here, the mounted work 6 is taken out by the mounter 4 while it is stopped for a predetermined period (see FIG. 10F). The empty movable table 33 is then retracted and tilted by the cam 34 (see FIG. 10G), returns to the initial state, and is ready for feeding the next workpiece 6.
[0015]
[Problems to be solved by the invention]
In such a component supply device, a natural fall due to gravity is used to send out a component packed in a cylindrical container, and a long arm or push pin is inserted and extracted to pull out or extrude the component from the cylindrical container. This avoids the use of complicated and fragile mechanisms. Specifically, the storage mechanism, the guide mechanism, and the feeding mechanism are inclined as described above.
On the other hand, a mounting apparatus that cooperates with it mounts a component on a printed circuit board or the like that is maintained in a horizontal state so that the component does not slide down, and the mechanism of the device generally takes out the component by the mounting head. In some cases, it is assumed that the component to be mounted is supplied to the component removal position in a horizontal state.
[0016]
For this reason, in the conventional component supply apparatus, the leveling mechanism which levels an inclined component is required. In addition, when the leveling mechanism is operated, it is necessary to separate the leading part from the following part, and for this reason, a standby mechanism for stopping the following part from moving and moving due to gravity is also required. The Furthermore, if the leveling mechanism is operated at high speed, the parts may jump out when leveling the parts transferred from the guide mechanism to the feeding mechanism. In order to prevent such jumping out, it is necessary to add a mechanism for pressing the component from the top only during the operation and sucking the bottom by vacuum suction from the bottom.
These leveling mechanism, standby mechanism, and suction holding mechanism are all concentrated at the front end of the guide mechanism.
[0017]
By the way, the mounting components handled by the component supply device are becoming increasingly smaller, and accordingly, the guide mechanism and the feeding mechanism of the component supply device have to be made compact.
However, if the guide mechanism and feeding mechanism are simply reduced, the leveling mechanism, standby mechanism, and suction / holding mechanism must be reduced in the same way for the centralized arrangement. It becomes difficult to use general machine elements such as. The use of special or special machine elements increases the cost and makes assembly / adjustment and maintenance difficult.
[0018]
Further, in order to meet the demand for high-speed processing, if it is attempted to further increase the operation speed of a leveling mechanism or the like based on a cam mechanism, inconvenience arises from the viewpoint of device life and reliability.
Therefore, in order to meet the demands for downsizing and speeding up while avoiding inconveniences such as cost increase, a leveling mechanism, a standby mechanism, and a suction holding mechanism are not arranged centrally, or even without these mechanisms It becomes a problem to devise a mechanism or the like that can supply parts from a container.
[0019]
The present invention has been made to solve such a problem, and an object thereof is to realize a component supply apparatus that can be easily reduced in size and increased in speed.
[0020]
[Means for Solving the Problems]
About the 1st thru | or 4th solution means invented in order to solve such a subject, the structure and effect are demonstrated below.
[0021]
[First Solution]
The component supply apparatus of the first solution means (as described in claim 1 at the time of filing) has a storage mechanism for storing a cylindrical container of components and a hollow guide path, and is sent out from the cylindrical container. In a component supply apparatus comprising: a guide mechanism that sequentially guides the guided parts via the guide path; and a feeding mechanism that feeds a guided leading part to a parts take-out position. A means for blowing air into the cylindrical container via a storage mechanism is provided, and the storage mechanism, the guide mechanism, and the feeding mechanism are arranged horizontally side by side.
[0022]
In such a component supply apparatus of the first solution, air is blown into the cylindrical container accommodated in the storage mechanism through the storage mechanism when the supply mechanism supplies the components. Then, parts are sent out from the cylindrical container by the air pressure and air flow, but since the storage mechanism, the guide mechanism, and the feeding mechanism are arranged horizontally, the parts sent out from the cylindrical container are in order. It moves to the feeding mechanism via a hollow guide path in the guiding mechanism, and the leading component is fed to the component picking position. Then, since the part is already horizontal, it is taken out from the part take-out position as it is. In this way, when the supply of the leading part is completed, the next part is sent in order, the same is repeated, and a series of parts is supplied.
[0023]
In this case, since the parts are pushed forward by air blowing, there is no need to use an elongated arm or a push pin. There is no need to tilt the storage mechanism, the guide mechanism, or the feeding mechanism. Accordingly, a leveling mechanism becomes unnecessary. Further, a suction holding mechanism for preventing the part from popping out during the movement / rotation operation of the leveling mechanism is also unnecessary.
[0024]
This eliminates the leveling mechanism and suction / holding mechanism that have hindered downsizing and speeding up, and newly installed air blowing means can be distributed in the storage mechanism. The restrictions are relaxed.
Therefore, according to the present invention, it is possible to realize a component supply apparatus that can be easily reduced in size and speed.
[0025]
[Second Solution]
The component supply device of the second solution means is the component supply device of the first solution means (as described in claim 2 at the beginning of the application), wherein the guide mechanism has the guide path of the component supply device. The feed mechanism extends to a take-out position, and the feeding mechanism is provided with an opening / closing mechanism that opens and closes the part take-out position when feeding the parts.
[0026]
In such a component supply apparatus of the second solving means, when the component is guided to the feeding mechanism by the guide mechanism, the component is immediately fed to the component removal position. And when feeding parts such as feeding and subsequent parts removal, the part removal position is opened and closed by the opening and closing mechanism, so that even if the parts move at high speed when the parts are fed in, the popping out is surely prevented The component can be removed without moving the component simply by operating the opening / closing mechanism when the component is removed.
[0027]
Thereby, even if the component supply operation is further speeded up, the processing is surely performed. In addition, the operation of only the opening / closing mechanism that does not require component mounting can be realized in a simpler and simpler manner than the operation of a movable base on which components are mounted.
Therefore, according to the present invention, it is possible to realize a component supply device that can be more easily reduced in size and speeded up.
[0028]
[Third Solution]
A component supply device of the third solution means (as described in claim 3 at the beginning of the application) is the component supply device of the first and second solution means described above, and is the component supply device of the feed mechanism. And a switching mechanism for intermittently blowing air into the cylindrical container.
[0029]
In the component supply apparatus of the third solution means, when the component is fed to the component take-out position by the feeding mechanism, the cylindrical mechanism is used by the switching mechanism in conjunction with the component feeding. Air blowing into the container is interrupted, and the driving force is selectively transmitted depending on whether or not the parts need to be moved. When the air blowing is cut off and the driving force for moving the parts is lost, all the parts stop moving because the storage mechanism, the guide mechanism, and the feeding mechanism are horizontal. Therefore, if the leading part is taken out in this state, the part is taken out without affecting or being influenced by the following part.
[0030]
Therefore, even if a standby mechanism for forcibly stopping subsequent components is not explicitly provided, it is possible to take out the components.
As a result, in addition to the leveling mechanism and the suction holding mechanism, it is possible to omit the standby mechanism that has been an obstacle to downsizing and speeding up, and the design constraints are further eased.
Therefore, according to the present invention, it is possible to realize a component supply apparatus that can be further reduced in size and speeded up.
[0031]
[Fourth Solution]
A component supply device of a fourth solution means (as described in claim 4 at the beginning of the application) is the component supply device of the first to third solution means, wherein the storage mechanism is a cylindrical container. A detector that is capable of storing a plurality of components and that includes a discharge mechanism that sequentially discharges them, and that detects the presence or the number of cylindrical containers stored in the storage mechanism includes the storage mechanism. And means for enabling the discharge operation of the discharge mechanism only when a plurality of presences are detected based on the output of the detector.
[0032]
In the component supply apparatus of the fourth solving means, when a plurality of cylindrical containers are stored in the storage mechanism, the components are supplied and discharged from the empty container in order. . In this way, parts are supplied continuously for a plurality of cylindrical containers. At that time, if only one cylindrical container remains in the storage mechanism, this is based on the output of the detector. Since the discharge operation of the discharge mechanism is suppressed, the last cylindrical container remains in the storage mechanism without being discharged. Then, the air blown into the cylindrical container is sent to the guide path, and the parts remaining in the guide path are advanced, so that all the parts are sent to the parts take-out position.
[0033]
As a result, it is possible to reliably supply all the components without waste without adding a special mechanism or the like for feeding the remaining components to the guide mechanism close to the feeding mechanism. In addition, since the detectors necessary for this purpose may be attached to the storage mechanism, the arrangement design is easy with few restrictions.
Therefore, according to the present invention, it is possible to easily achieve a reduction in size and speed without wasting parts.
[0034]

[0035]
In this component supply device, the stick storage unit 50, the rail unit 60, the workpiece feeding unit 70, and the controller 80 are replaced with the stick storage unit 10, the rail unit 20, the workpiece feeding unit 30, and the controller 40, respectively. This is different from the conventional apparatus in that these mechanisms arranged in a straight line are supported horizontally by a column 3a and a column 3b instead of the column 3 (see FIG. 1). Thereby, the storage mechanism, the guide mechanism, and the feeding mechanism are arranged horizontally.
In addition, since the same code | symbol was attached | subjected and shown to the component similar to the past, the overlapping description is abbreviate | omitted and it demonstrates focusing on those differences hereafter.
[0036]
The stick storage unit (storage mechanism) 50 is fixed to the guide 16a in order to detect whether or not there is the second stick 5 from the bottom, in addition to being fixed horizontally when attached to the column 3a. A sensor 58 is attached (see FIGS. 1 and 2), and a path of compressed air P is provided to the escaper 54 instead of the escaper 14 in order to blow air from its rear end into the inner cavity of the lowermost stick 5. It is also different from the stick storage unit 10 in that a perforation is formed (see FIGS. 1D, 3C, and 3E). Accordingly, the stick storage unit 50 can store a plurality of sticks (tubular containers), and a stick sensor (detector) for detecting the presence or absence of the cylindrical containers stored therein is attached. At the same time, there is provided means for blowing air into the cylindrical container through the mechanism.
[0037]
Further, the basic shape such as the outer shape of the escaper 54 follows the escaper 14, and the escaper 13 paired therewith and the air cylinders 11 and 12 for driving them are also the same as in the prior art (FIG. 3A). , (B), (d)). As a result, the stick storage unit 50 has a built-in discharge mechanism for sequentially discharging the stored sticks. It should be noted that the interval between the front plate 16 and the rear plate 17 can be adjusted by the fastening portion 15a (see FIG. 3B) and can be applied to the sticks 5 of various sizes (see FIG. 3B). Thus, the distance between the side plates 15 can also be adjusted (see FIG. 3C).
[0038]
The rail portion 60 (guide mechanism) is fixed horizontally when being attached to the pillars 3a and 3b, the air cylinder 21 and the air cylinder 22 are removed, and the front end is a workpiece 6 by the mounter 4. This is also different from the rail part 20 in that the part feeding position 75 is reached and the work feeding part 70 is attached around its front end (see FIG. 2). As a result, the rail portion 60 has a hollow rail lumen 24b (guide path) extending to the component pick-up position 75 of the workpiece feeding portion 70, and the workpiece 6 (components) fed out from the stick (tubular container). ) Are sequentially guided to the parts removal position via the rail lumen 24b.
[0039]
Further, the rail cover 24 a of the rail portion 60 has a tip portion removed from the rail body 24, which is a component takeout position 75 so that the work 6 can be taken out by the mounter 4 from above the component takeout position 75. It has become. Furthermore, the rail cover 24a is formed of a transparent member such as acrylic so that the internal state of the rail portion 60 can be seen, and can be attached to and detached from the rail body 24 so that the rail lumen 24b can be cleaned. ing.
[0040]
As described above, the workpiece feeding unit 70 (feeding mechanism) is provided at the front end of the rail unit 60 (see FIGS. 1C and 2), and is the leading workpiece guided through the rail lumen 24b. 6 (parts) is sent directly to the part picking position 75, the stopper 74 stops the advance of the workpiece 6 at the part picking position 75, and the shutter 71 covers the stopper 74 or the part picking position 75. An air cylinder 76 for driving forward and backward movement of the shutter 71 and a mechanical valve 72 disposed in a side surface of the rail body 24 belonging to the movable range of the shutter 71 are provided. Since the space at the part take-out position 75 is also surrounded by the stopper 74 and the rail body 24, the work 6 there is restricted not only to move forward but also to the left and right so that it can be taken out only from above. In addition, the stopper 74 can be adjusted in the front-rear position when attached to the rail body 24 so that it can be used for parts having different lengths if the cross-sectional shape is the same.
[0041]
The movable range of the shutter 71 comes from the position above the stopper 74 at the time of forward movement and opens above the part removal position 75 (see FIG. 2 and FIG. 6A), and from above the part removal position 75 at the time of backward movement. It occupies up to the place (see FIG. 6C) where the space of the part removal position 75 is closed. As a result, the workpiece feeding unit 70 is provided with an opening / closing mechanism for opening / closing the part removal position. Further, the mechanical valve 72 is provided where the operating portion of the mechanical valve 72 is pushed when the shutter 71 is retracted (see FIG. 6C), and when the mechanical valve 72 is operated, the mechanical valve 72 and beyond. Air tube piping (not shown) is provided so that the compressed air P is supplied to the passage of the escaper 54 via the flow rate control valve 73 (see FIG. 4). Thus, the component supply device includes a valve (switching mechanism) that intermittently blows air into the stick (cylindrical container) in conjunction with the advance / retreat of the shutter 71.
[0042]
The controller 80 (control unit) is not required to generate the slider operation output D in response to the air cylinder 31 and the electromagnetic valve 44 being omitted, and the processing procedure is changed as will be described later. It is also different from the surroundings of the controller 40 that the compressed air supply state is changed from the air cylinders 21 and 22 to the air cylinder 76 and the switch SW is inserted in the stick discharge output B line. (See FIG. 4). The air cylinder 76 moves backward when the component feed output C is turned on by switching the compressed air supply state of the electromagnetic valve 43, and moves forward when the component feed output C is turned off.
[0043]
The switch SW is controlled by a detection signal of the stick sensor 58. When the stick 5 is detected at the stick sensor 58, the switch SW is turned on to transmit the stick discharge output B to the electromagnetic valve 42, while the stick sensor 58 is detected. If the stick 5 is not present, the transmission of the stick discharge output B to the solenoid valve 42 is cut off. Thus, the component supply device is provided with means for enabling the discharge operation of the discharge mechanism only when the presence of a plurality of cylindrical containers is detected based on the output of the stick sensor 58 (detector). It has become a thing.
[0044]
The use mode and operation of the component supply apparatus of this embodiment will be described with reference to the flowchart of FIG. 5 and the operation diagram of FIG. The operation of discharging the empty bottom stick is the same as in the prior art except that the operation of the stick sensor 58 and the switch SW is limited to the case where a plurality of sticks 5 are present. The operation will be described in detail.
[0045]
When the operation of the controller 40 or the like is started after the several sticks 5 are accommodated in the stick accommodating unit 50, the controller 40 supplies the components from the mounter 4 with the stick discharge output B and the component feeding output C turned off. Wait for the sending instruction A (step S1). In this state, since the shutter 71 is moving forward and the mechanical valve 72 is not operated, no air is blown from the escaper 54 to the stick 5 (see FIG. 6A). Note that the switch SW is in a conductive state in response to detection of the presence of the stick 5 by the stick sensor 58.
[0046]
In such a state, when the controller 40 receives a component feeding instruction A from the mounter 4, first, the component feeding output C is turned from OFF to ON (step S2). Then, the rod of the air cylinder 76 is retracted, and the shutter 71 is also retracted accordingly (see FIG. 6B), and the space at the component pick-up position 75 is closed by the shutter 71 and the mechanical valve 72 is activated. Then, the compressed air P is blown into the rear end of the lowermost stick 5 (see FIG. 6C).
[0047]
While the controller 40 is waiting for a predetermined time (step S3), the last work 6 in the lowermost stick 5 is pushed forward by the compressed air P and moves forward. All the workpieces 6 are also pushed in sequence and move forward until they move until the leading workpiece 6 contacts the stopper 74 (see FIG. 6C).
In this way, the leading work 6 is sent to the part picking position 75.
[0048]
Thereafter, the component feed output C is returned from ON to OFF by the controller 40 (step S4). Then, the rod of the air cylinder 76 moves forward, and the shutter 71 moves forward accordingly, and the operation of the mechanical valve 72 and the blowing of the compressed air P are stopped, and the upper portion of the component pick-up position 75 is opened (FIG. 6). (See (d)).
[0049]
Then, while the controller 40 is waiting for the elapse of a predetermined time (step S5), the top work 6 is taken out from the part take-out position 75 by the mounter 4 (see FIG. 6E).
Thus, one workpiece supply is completed.

Then, based on the detection signal of the component detection signal E, a check is made by the controller 40 as to whether or not the workpiece 6 remains after that (step S6). If the workpiece 6 remains, it immediately returns to the initial state (branch to step S1) and prepares for the feeding of the next workpiece 6 (see FIG. 6A). On the other hand, when the workpiece 6 does not remain, the stick discharge output B is turned ON for a predetermined period (steps S7 to S9). Then, the lowest empty stick 5 is discharged by the stick discharge mechanism (see FIG. 8), but when the lowest stick 5 is the last one, it is left as it is. Then, the supply of the workpieces 6 one by one is repeated.
In this way, all the workpieces 6 are supplied to the take-out position by the mounter 4.
