With such a configuration, each work supply unit 24
By attaching and detaching the mounting base 36 to the corresponding pedestal 32, each of the components can be attached to and detached from the pedestal 26 as a fixed part in an independent state.

Second, in the middle part of the above-mentioned chute stand 34, there is an opening 34 large enough for one stick S to be inserted through.
a is formed. The above-mentioned cassette 38 is attached in a state located above this frontage 34a.

In this way, in the cassette 38 of each workpiece supply unit 24, the workpiece W is moved from the stick S brought to the lowest workpiece take-out position, as shown by the arrow B, along the inclination direction of the chute table 34. is slid down and taken out, and is set to stop by contacting a stopper 34b formed at the front end of the chute stand 34 and maintain that position. Note that a separation position P1 of the work W is defined at the position where the stopper 34b comes into contact.

Here, among the above-mentioned front and rear multiple pairs of sliding members 30, a ball screw 44 constituting the first moving mechanism 14 is located behind each sliding member 30 located at the rear along the direction of arrow A. It is placed in an extended position. Each rear sliding member 30 is screwed into this ball screw 44, and when this ball screw 44 is rotationally driven by a drive motor (not shown), the sliding member 30 (therefore, The work supply unit 24) attached to the sliding member 30 through the engagement between the pedestal 32 and the mounting pedestal 36 moves along the direction of arrow A on the guide rail 28.

On the other hand, on the chute table 34 and on the side in the direction of arrow B relative to the cassette 38, the above-mentioned work separation mechanism 40 is disposed. This work separation mechanism 40 is configured to be operated by pneumatic pressure as pneumatic operating means,
It is equipped with a pneumatic cylinder 48 connected to an electromagnetic switching valve (not shown) via an air supply device [46].

This distance pressure cylinder 48 is constructed by supplying air from a pneumatic source (not shown) to the upper part by an electromagnetic switching valve.
It includes a piston rod 50 that protrudes downward and is drawn upward by being supplied to the lower part.

The work separation mechanism 40 also includes a swing stay 54 whose central portion is rotatably supported by the chute stand 34 via a support shaft 52. A lower end of the above-mentioned pneumatic cylinder 48 is attached to a portion of the swing stay 54 that is deviated from the shaft support toward the arrow B side, with a piston rod protruding downward. Further, one end of the swinging stay 54 on the arrow B side is bent 90 degrees so that it can substantially come into contact with the upper surface of the chute stand 34 with the piston rod 50 being pushed downward. A presser mechanism 56 is attached to the other end of the swing stay 54 to press and lock the upper surface of the workpiece W sliding down on the chute table 34.

As shown in detail in FIG. 3, the holding mechanism 56 includes a housing 58 that is fixed to the other end of the swing stay 54 and has a substantially cylindrical shape with an open bottom surface, and a housing 58 that can be vertically protruded downward from the housing 58. a presser member 60 movably disposed;
It is comprised of a coil spring 62 that always urges the holding member 60 downward.

As described above, the workpiece separation mechanism 40 is configured so that when air is supplied to the pneumatic cylinder 48 and the piston rod 50 is pushed downward, the swinging stay remains as shown in FIG. 54 rotates clockwise around the support shaft 52, and a locking portion 54a defined at one bent end of the swing stay 54 is brought to a position away from the top surface of the chute table 34. become. As a result,
The workpiece W at the locking position P2 is released from the locking state by the locking portion 54a, passes below the locking portion 54a, and slides down to the separation position P.

In this unlocked state, the other end of the swing stay 54 to which it is attached is biased downward, so that the presser mechanism 56 moves to a standby position P defined immediately after the locking position P2. The workpiece W that has slipped down is held down and brought to a halt.

Due to this state force, the supply of air to the pneumatic cylinder 48 in the work separation mechanism 40 is stopped, and the piston rod 50 is pulled upward by the biasing force of a return spring (not shown), and the swing stay 54 is , around the support shaft 54 in a counterclockwise direction based on the weight of the pneumatic cylinder 48. As a result, the holding mechanism 56 does not press down the workpiece W at the standby position P3, and the workpiece W at the standby position P3 is moved to the locking position P3.
It will slide towards 2.

On the other hand, in response to the counterclockwise rotation of the rocking stay 54, the locking portion 54a thereof is biased downward, and as a result, the locking state of the locking portion 54a is achieved and the locking stay 54 slides from the standby position P3. The workpiece W that has fallen is locked at the locking position P2.

In addition, as the workpiece W slides down from the standby position P3 toward the locking position P2, the workpiece W slides down from the stick S at the workpiece supply position due to its own weight to the standby position P, and reaches the locking position P2. By coming into contact with the rear end of the locked workpiece W, it is held at the standby position P8.

In this way, only - pieces of work W are brought to the separation position Pl in a separated state.

In this way, the separation position P of the next workpiece W is reached.

The series of separation operations is completed.

Here, in each workpiece supply unit 24, with one workpiece W separated and held at the separation position Pl, the above-mentioned first movement mechanism 14 moves the component storage/supply mechanism 12 in the direction of arrow A. By moving along the direction shown, the workpiece W held at the separation position P1 in the workpiece supply unit 24 containing the desired part type of workpiece W is brought to the pick-up position α1.

The detection mechanism 64 is composed of a photocoupler and includes a light emitting element 64a located above and a light receiving element 64b located below receiving light emitted from the light emitting element 64a. That is, in this detection mechanism 64, when the light receiving element 64b receives light from the light emitting element 64a, the standby position P3
It is detected that the workpiece W is not present at
It is set to detect the presence of the workpiece W at the location.

Next, in each workpiece W supply unit 24, the support structure of the stick S in the cassette 38 described above and the structure of the empty stick ejection mechanism 42 are shown in FIGS. 2, 4, and 5.
This will be explained in detail below with reference to the figures.

66b, 66c, and 66d are provided in an upright position. Here, each stick S is formed into a trapezoidal shape from the front, and both left and right ends of the bottom of each stick S can be locked from below.

Inside this cassette 38, there is a stick locking mechanism 68 for releasably locking the second and higher sticks S, S, ... from the bottom, and a stick locking mechanism 68 for releasably locking the sticks S1 at the bottom.
An empty stick discharge mechanism 42 is provided for locking the stick S and for discharging the empty stick S' downward when the stick S becomes empty.

Here, this stick locking mechanism 68 is configured in a left-right symmetrical shape as shown in FIGS. 4 and 5, and in the following explanation, the left side in the figure (the near side in FIG. 2)
Only the configuration on the right side will be explained, and the explanation on the configuration on the right side will be omitted.

This stick locking device tll168 includes an abbreviated first locking piece 70a that locks the front and rear bottoms of the stick S2 in the second row from the bottom from below, among the sticks S stacked up and down. 70b is rotatably supported at the upper end. That is, as shown in FIG. 2, the front and rear bottom portions on the left side (the front side in the figure) of the second stick s2 from the bottom are locked by first locking pieces 70a and 70b, respectively.

Here, the upper ends of the first locking pieces 70a, 70b are
They are both fixed to a common first transmission shaft 72 extending along the direction. Both ends of the first transmission shaft 72 are connected to the first and second regulating plates 66 a, 6 located on the left side described above.
6b, respectively, so as to be rotatably supported.

In order to rotate this first transmission shaft 72, a second transmission shaft 74 is disposed on the outside of the central portion thereof and extends along a direction perpendicular to this. .

As shown in FIGS. 2 and 5, the second transmission shaft 74 is supported via a shaft guide 76 so as to be movable along this extending direction. In this second transmission shaft 74, a connecting member 78 is slidably inserted in the portion intersecting with the first transmitting shaft 72 along the axial direction, and the tip of this connecting member 78 is connected to the first transmitting shaft 72. It is fixed to the transmission shaft 72. Here, the upper end of this second transmission shaft 74 is connected to the piston rod 7 of a pneumatically actuated drive cylinder 75, as shown in the figure.
The piston rod 75 is set so as to face the lower end of the drive cylinder 5a from below.
It is set to be in contact with a, and to be moved up and down together with this in the abutted state.

Here, only one drive cylinder 75 is disposed corresponding to only the work supply unit 24 brought to the work supply position, and in this way, in this embodiment, the drive cylinder 75 When the piston rod 75a is activated and the piston rod 75a is pushed down, it abuts only the second transmission shaft 74 provided in the work supply unit 24 set at the work supply position from above, and drives it to move downward. It's going to happen. Further, this drive cylinder 75 is connected to a pneumatic source 77 composed of a pneumatic pump or the like, and receives a supply of compressed air from this pneumatic source to push and drive the corresponding piston rod 75a downward. It is structured like this.

Note that a stopper 80 is fixed to a portion of the second transmission shaft 74 located between the connecting member 78 and the shaft guide 76. This stopper 80 and the connecting member 7
A coil spring 82 is mounted around a portion of the second transmission shaft 74 between the second transmission shaft 74 and the second transmission shaft 74 . That is, when the second transmission shaft 74 is driven to be pushed downward, this downward driving force is set to be transmitted to the connecting member 78 via the coil spring 82. .

That is, when the drive cylinder 75 described above is not activated, the second transmission shaft 74 is biased upward by a biasing member (not shown), and each of the first locking pieces 70a, 70
b is set to not support the second stick S2 from the bottom.

On the other hand, compressed air is supplied from the pneumatic source to the drive cylinder 7.
5 is activated, the second transmission shaft 74 is pushed down, and this pushing down force is transmitted to the connecting member 78 and the first transmission shaft 72 via the coil spring 82.
Each first locking piece 70a, 70 fixed to the transmission shaft 72 of
b rotates inward and presses the second stick S2 from the bottom.
will be supported from below.

On the other hand, the empty stick discharging mechanism 42 includes a second locking piece 84a that supports the lower surface of the stick Sl located at the lowest workpiece take-out position from below at both the front and rear ends, respectively;
84b is rotatably supported at the outer end. Here, the second locking pieces 84a and 84b are both fixed to a common third transmission shaft 86 extending along the direction of arrow B. Both ends of this third transmission shaft 86 are the first and second regulating plates 66a located on the left side described above.

66b, respectively, so as to be rotatably supported.

Here, when the drive cylinder 75 is not activated, the lower end of the second transmission shaft 74 is terminated at a position spaced upward by a predetermined distance from the third transmission shaft 86, as shown in FIG. ing. A pressing member 88 is integrally formed at the lower end of the second transmission shaft 74 and projects inward. Further, the central portion of the third transmission shaft 86 located directly below the second transmission shaft 74 is pressed downward by the above-mentioned pressing member 88, so that the third transmission shaft 86 A driven member 9 that rotationally drives the
0 is fixed in a state extending outward. Although not shown, this driven member 90 is formed with an elongated shape extending in the front-rear direction.

On the other hand, a rod 88a is fixed to the lower surface of the pressing member 88, and is inserted into the elongated hole from above.The upper end of the rod 88a has a large diameter portion 88b formed to have a larger diameter than the elongated hole. are integrally formed.

Note that this third transmission shaft 86 is connected to the second locking piece 8 by means of a torsion spring (not shown) that connects the lowest stick S1 to the second locking piece 86.
4a and 84b are biased to the supporting position. Also,
As shown in FIG. 2, below the opening 34a mentioned above,
A discharge chute 92 is provided for guiding the empty sticks S' discharged from here to a waste box (not shown).

Since the empty stick discharging mechanism 42 is configured as described above, the drive cylinder 75 is activated and the first locking piece 7
After pushing down the second transmission shaft 74 so as to support the second stick S2 from the bottom by 0a and 70b, the pressing member 88 fixed to the lower end of the second transmission shaft 74 is further pushed down. The large-diameter portion 88b contacts the driven member 90 of the third transmission shaft 86 and pushes and rotates it, thereby controlling the locking state of the lowest stick S by the second locking pieces 84a and 84b. It will be canceled. In this way, the stick S at the lowest stage falls downward through the opening 34a as an empty stick S', and is guided into the waste box through the discharge chute 92.

Note that the second transmission shaft 74 is connected to the locking pieces 70a and 70 of the multi-tube 1.
After rotating the stick S2 inward and locking the second stick S2 from the bottom, it is further pushed down, but if we focus on the relationship with the connecting member 78, After the locking operation by the locking pieces 70a, 70b, the coil spring 82 simply contracts in response to the lowering of the second transmission shaft 74, and the first locking piece 70a.

This does not affect the locked state of 70b.

After the empty stick S' is ejected in this way,
The drive cylinder 75 operates to lift the second transmission shaft 74. As a result, first, the second locking pieces 84a, 8
4b returns to a state in which the lowest stick S can be locked. However, at this point, the lowest stick S1 has been ejected as an empty stick S', so the operation of the second locking pieces 84a, 84b is an idle operation.

Further, as the second transmission shaft 74 rises, the coil spring 82 that had been contracted begins to expand, and the connecting member 78 is biased upward.

As a result, the first transmission shaft 72 is connected to the first locking piece 70 a
, 70 b will be rotated outward. In this way, the first locking piece 70a.

The locking state of the second stick S2 from the bottom by the stick 70b is released, and the locking state of the second stick S2 from the bottom is released, and until now the first locking piece 70a.

The sticks S, S3, .

Therefore, the sticks that were the second or higher from the bottom will now become sticks S, S2, etc. from the bottom, and from the bottom stick S1, the workpiece W will move along the slope due to its own weight. It will be taken out by falling.

In this way, a series of operations for discharging empty sticks S' and supplying sticks S1 to the lowest stage are completed.

At this point, the locking state of the second stick S2 from the bottom is released, and the sticks S, S,..., which have been locked to the first locking pieces 70a70b, fall and become the second sticks S2. When exchanging the sticks that are to be locked with the locking pieces 84a and 84b, this stick exchanging operation is smoothly performed.
In addition, in order to ensure the execution, as shown in FIG. 2 again, the work supply unit 2 brought to the work supply position
Immediately above the No. 4 cassette 38, a biasing mechanism 94 is disposed to bias the sticks stored in the cassette 38 downward.

In this embodiment, the biasing mechanism 94 is located at the top stage in order to bias the sticks downward in a non-contact manner regardless of the number of sticks remaining in the cassette 38. An air nozzle 96 is provided to blow compressed air onto the stick. Here, this air nozzle 96 is similarly connected to the air pressure source 77 for supplying compressed air to the drive cylinder 75 in the above-mentioned empty stick discharge mechanism 42, and receives the supply of compressed air as working air from there. It is configured. Further, the air nozzle 96 is attached to the stay 98 together with the drive cylinder 75, and the stay 98 is fixed to the upper frame 100 connected to the above-mentioned pedestal 26. ing.

By providing the biasing mechanism 94 in this way, when the empty stick discharging mechanism 42 operates and discharges the empty stick S° located at the lowest stage downward, the second and higher real sticks from the bottom are moved one stage at a time. When the stick is dropped, this biasing mechanism 94 is activated and compressed air is ejected from the air nozzle 96 toward the top stick. As a result,
Pushed by this compressed air, the topmost stick is urged downward and forced to descend. In this way, the second and higher real sticks from the bottom are forcibly pushed down by this biasing mechanism 94 and fall smoothly without getting caught on the way, making it easy to exchange empty sticks with real sticks. This will be done reliably and smoothly.

As described in detail above, in the mounting machine 10 of this embodiment, by operating the biasing mechanism 94 when exchanging the empty stick and the real stick, the real stick is reliably pushed down. Smooth replacement work
And it will definitely be carried out. Further, in this embodiment, the drive cylinder that drives the empty stick discharging mechanism 42 is used only for the work supply unit 24 that is actually performing the work supply operation, that is, the work supply unit 24 that is in the work supply position. 75 are connected,
Further, it is set so that the urging force of the urging mechanism 94 acts.

In other words, only one drive cylinder 75 and only one urging mechanism 94 are provided corresponding to this work supply position. In this way, in this embodiment, compared to arranging the drive cylinder 75 and the urging mechanism 94 in accordance with each work supply unit 24,
It is possible to significantly reduce the number of installed devices, simplify the wiring, and reduce wiring work when switching functions.

This invention is not limited to the configuration of the one embodiment described above (it goes without saying that various modifications can be made without departing from the gist of the invention).

For example, in the embodiment described above, the discharge chute 92 is located below the pickup position α1 on the pedestal 26.
to eject the empty stick S' so that it is fixed at
Although it has been described that this is carried out during the pick-up operation of the workpiece W, the present invention is not limited to such a configuration, and can be performed by fixing the discharge chute 92 to the chute stand 34 in each workpiece supply unit 24. This means that the empty stick S' can be ejected while the work supply unit 24 is moving. In this way, in the case of the above-mentioned embodiment, the empty stick S' must be ejected while it remains at the pick-up position α1, and there is a risk that the takt time will be extended due to the pressure evacuation operation. However, it is also possible to shorten the takt time by discharging empty sticks while the work supply unit 24 is moving.

Further, in the above-described embodiment, the urging mechanism 94 is of a pneumatically actuated type equipped with an air nozzle 96, but the present invention is not limited to such a configuration. It is also possible to directly push down the stick located at the top level via an elastic member such as a spring.
