Parts trays to be taken out in order, parts are arranged in advance on a medium such as tape, and the tape is wound in a coil and supplied, and an array supply method using a tape, coil, hoop type, and (2) randomly stacked For example, there is a bulk-stacking type automatic supply method for arranging and supplying the separated parts. Further, in recent years, the number of types of chip components to be handled tends to increase, but in this case, the current situation is to create a component feeder for each type of chip components. In addition, the size of the chip parts to be handled is becoming smaller and lighter, but when the small and light chip parts are placed on a conveyor belt or the like and conveyed at a fast timing, the movement of the conveyor belt causes disturbance. The alignment of existing chip parts is disturbed. If the alignment is disturbed, problems such as difficulty in picking up the chip components on the conveyor belt occur. Therefore, it is desirable that the conveyor belt is always driven at a regular and stable speed.

[0004]

As described above, when the chip parts are placed on the conveyor belt and conveyed, in order to prevent the alignment of the chip parts on the conveyor belt from being disturbed during the conveyance, It is desired that the belt is always driven at a regular and stable speed.

The present invention has been made in view of the above problems, and it is an object of the present invention to particularly drive a conveyor belt that carries a workpiece (chip component) and conveys it to a predetermined position at a regular and stable speed. An object of the present invention is to provide a component supply method and apparatus capable of transporting and supplying even a small and light work to a predetermined position without disturbing the alignment. Further, other objects will be clarified sequentially in the contents described below.

[0006]

In order to achieve the above object, according to the present invention, as the component supply device, the chip-shaped workpieces that are input are aligned and conveyed to the workpiece pick-up position on the mounting machine side. In a component supply device including an endless conveyor belt, a plurality of pulleys that guide the rotational movement of the conveyor belt, and a driven mechanism that is driven integrally with the pulleys are provided. A load is always applied to the drive to absorb a power fluctuation from the outside to provide a damper for stabilizing the rotation speed of the conveyor belt.

Further, in order to achieve the above object, in the present invention, a component provided with an endless conveyor belt for aligning chip-shaped workpieces that are loaded and transporting them to the workpiece pick-up position on the mounting machine side. In the supply method, a damper that applies a load to the drive of a driven mechanism that is integrally driven with a plurality of pulleys that rotate integrally with the conveyor belt to absorb power fluctuations from the outside is provided, and the damper is used. The parts are conveyed while stabilizing the speed at which the conveyor belt rotates.

According to this, since the driven mechanism is always loaded by the damper and the transport belt is driven while being attenuated by the load, a predetermined speed for moving the belt from the outside or the like is predetermined. Even if an external force is applied, this can be suppressed to stabilize the speed, and the parts can be always aligned and supplied to a predetermined position.

Similarly, as shown in FIGS. 3 and 4, the lever 33 has a mounting hole 33c in the middle portion, through which the portion 14c of the support shaft 14 passes. The lever 33 is attached to the base 2 via the support shaft 14 in a state where the support shaft 14 penetrates the mounting hole 33c and is freely rotatable. Further, one end 33a of the lever 33 extends downward, and the other end 33b extends substantially horizontally in the first recess 7a toward the second recess 7b. On the other hand, on the other end 33b side, a connecting pin 38 is attached to the tip and a protruding shaft 39 is formed in the middle. In addition, a through hole 40 is vertically formed in the base 2 so as to correspond to the protruding shaft 39 and open in the upper surface 2b and the first recess 7a. An operating lever 41 is inserted into the through hole 40 from the side of the recess 7b, and the lower end of the operating lever 41 is placed on the outer peripheral surface of the protruding shaft 39. When the operation lever 41 is pushed down, the protruding shaft 39
The lever 33 can be rotated downward via the. Further, on the one end 33a side of the lever 33, the other end of a coil spring 43 having one end hooked on a pin 42 standing in the first recess 7a is hooked. 3, the lever 33 is always rotated upward (counterclockwise in FIG. 3), and the operating lever 41 is urged upward via the protruding shaft 39.

Further, in the coil spring 43, as shown in FIG.
As shown in detail in FIG. 2 and FIG. 13, a damper 86 made of urethane foam, felt, or the like is provided so as to substantially fill the space inside the coil spring 43, and the damper 86 expands and contracts. Is always applied, and the speed at which the deformation of the coil spring 43 returns can be damped. Then, when a sudden pressing force or the like is applied from the operation lever 41 side, this rapid pressing force is absorbed, and the speed at which the lever 33 is rotated from the lower side to the upper side and returned is attenuated, and as a result, The rotation speed of the conveyance timing belt 22 is stabilized.

The first ratchet pawl 34 is rotatably arranged on the other end 33b side of the lever 33 via a pivot 44, and the pawl portion 34a at the tip is engaged with the ratchet teeth of the ratchet wheel 32. ing. The first ratchet pawl 34 is engaged with the other end of the coil spring 45 whose one end is engaged with the pivot 44. When the ratchet wheel 32 is rotated in the arrow F direction (belt driving direction) in FIG. 3 by the urging force of the coil spring 45, the ratchet wheel 32 is rotated in the clockwise direction in FIG. When 32 tries to rotate in the direction opposite to the arrow F direction, the claw portion 34a is engaged with the teeth of the ratchet wheel 32 so that the ratchet wheel 32 does not rotate in the direction opposite to the arrow F direction.

The second ratchet pawl 35 is rotatably disposed above the lever 33 on the back surface 2d via a pivot 46, and the pawl portion 35a at the tip thereof is a ratchet wheel 32.
Of the ratchet teeth. The second ratchet pawl 35 has a winding spring 47 whose one end is engaged with a pivot 46.
The other end of is engaged. Then, when the ratchet wheel 32 is rotated in the direction of arrow F in FIG. 3 by the biasing force of the coil spring 47, as in the case of the first ratchet pawl 34, as shown in FIG.
When the ratchet wheel 32 tries to rotate in the direction opposite to the arrow F direction, the pawl portion 35a bites into the teeth of the ratchet wheel 32, and the ratchet wheel 32 moves in the arrow F direction. It has a structure that prevents it from rotating in the opposite direction. That is, the second ratchet pawl 35 is rotated on the ratchet wheel 32 by rotating the lever 33 in the clockwise direction in FIG.
Is moved in a clockwise direction while sliding, and when the ratchet wheel 32 is about to be rotated in a clockwise direction by the frictional force at this time, the claw portion 35a of the second ratchet pawl 35 causes the ratchet teeth of the ratchet wheel 32 to move. To prevent the ratchet wheel 32 from rotating in the direction opposite to the arrow F.

Therefore, in this timing belt drive system 31a, the lever 33 is attached to the central portion 14c of the support shaft 14 to which the drive pulley 11 is attached on one end side, and the knurled portion 1 is attached.
The ratchet wheel 32 is attached to 4b, and further the attachment screw 91 is attached to the screw hole 14d of the support shaft 14 from the other end side of the support shaft 14 so that the ratchet wheel 32 is prevented from coming off. As a result, the lever 33 can rotate freely with respect to the support shaft 14, and the ratchet wheel 32 can rotate together with the support shaft 14 and the drive pulley 11. Further, if the mounting screw 91 is removed as necessary, the ratchet wheel 32 can be replaced with a ratchet wheel 32 having a different number of teeth.

In the timing belt drive system 31a thus constructed, when the operating lever 41 is pushed down, the lever 33 moves in the clockwise direction in FIG.
When the operating lever 41 is moved to the lowermost side, the tip claw portion 34a of the first ratchet pawl 34 causes the ratchet teeth of the ratchet wheel 32 to move two times.
It is moved to the position where you overcame one. At this time, the ratchet wheel 32 has not yet rotated, and only the lever 33 and the first ratchet pawl 34 are moved. Next, when the pressing force of the operation lever 41 is released, the lever 33 is rotated counterclockwise in FIG. 3 by the urging force of the coil spring 43, and at this time, the ratchet wheel 32 is moved by the first ratchet pawl 34.
Is rotated in the direction of arrow F, and the operating lever 41 is pushed back up to the initial position.

The small chamber molded body side drive system 31b comprises a lever 49 rotatably mounted in the second recess 7b via a pivot 48, and one end 49a thereof is the other end of the lever 33. 33b, and the other end 49b extends into the third recess 7c. Further, a long hole 50 is formed at one end 49b of the lever 49, and a connecting pin 38 is engaged in the long hole 50 so that one end 49a is linked to the other end 33b of the lever 33. In addition, the lever 4 is provided between the lever 49 and the base 2.
A damper 8 made of felt or the like in a state of being pressed against 9
7 is fixedly attached to the base 2. Then, when the operation lever 41 is pushed down and the lever 33 is rotated downward (clockwise direction in FIG. 3), the lever 49 is rotated counterclockwise about the pivot 48 as a fulcrum in conjunction with this. To do. On the other hand, the rotation of the operation lever 41 is released and the lever 33 is released.
Is rotated upward (counterclockwise in FIG. 3), it is rotated in a clockwise direction in conjunction with this. Further, when the lever 49 is rotated, the lever 49 is always in pressure contact with the damper 87 and a load is applied. Therefore, for example, when a sudden operation force is applied from the operation lever 41 side, this A sudden operating force is attenuated by the load to cause the lever 49 to rotate stably,
As a result, the rotation of the transport timing belt 22 can be stabilized.

The small chamber molded body 3 is partially provided with a third recess 7c.
It has a base body 51 which is housed inside and is arranged so as to project from the upper surface 2 b of the base 2. More specifically, the base body 51 is made of aluminum, and the lower base body 51A accommodated in the third recess 7c and the upper part disposed so as to project from the upper surface 2b of the base 2 are disposed. Base 51B
And are integrated. A recess 52 is formed on the back surface 51b of the base body 51, and a buffer mechanism 53 is arranged in the recess 52. On the other hand, the base 5
The first small chamber 54 and the second small chamber 5 are provided on the first surface 51a.
5, a push-up piece guide groove 56, and a component guide groove 57 are formed. In addition, elongated holes 82 penetrating the front and back surfaces are formed in the base 51 so as to extend in the vertical direction, corresponding to the push-up piece guide grooves 56.

The buffer mechanism 53 has a pivot 58 penetrating through the elongated hole 82 and having one end projected on the front and back sides, and a spacer member 59 fixedly attached to one end of the pivot 58 on the back 51b side. A slide plate 61 having a long hole 60 for escaping the spacer member 59 and movably attached to the spacer 59 in the vertical direction; and an upper bent piece portion 61a of the slide plate 61 and the spacer member 59. It is composed of a coil spring 62 stretched between them. The other end 49b of the lever 49 is linked to the lower end of the slide plate 61 via a pivot 63.

In FIG. 3, when the lever 49 is rotated counterclockwise around the pivot 48 as a fulcrum, the slide plate 61 is pushed upward with the pivot 63 as a fulcrum. Then, the movement of the slide plate 61 is transmitted to the spacer member 59 via the coil spring 62, the spacer member 59 and the pivot 58 are moved upward, and the pivot 5 is moved.
A push-up piece 64, which will be described later, attached to the No. 8 is moved upward in the push-up piece guide groove 56. Further, in this state, when the lever 49 is rotated clockwise around the pivot 48 as a fulcrum, the slide plate 61 is pushed down around the pivot 63 as a fulcrum. Then, the inner surface of the long hole 60 of the slide plate 61 is brought into contact with the spacer member 59, and the spacer member 59 is forcibly pushed down together with the pivot 58,
As a result, the push-up piece 64 is moved downward.

Therefore, in the buffer mechanism 53 here, the force for the lever 49 to move the push-up piece 64 upward is
The lever 49 is not directly transmitted to the push-up piece 64, but is transmitted to the pivot 58 side via the coil spring 62. Therefore, the push-up piece 64 should not be forcibly pushed up due to, for example, clogging of a component (work). In such a case, the operating force on the lever 49 side is absorbed between the slide plate 61 and the spacer member 59, and damage to the work can be suppressed and protected.

Next, the front surface 51a side of the base body 51 will be described. On the front surface side of the upper base body 51B, a side plate 65 made of plastic is provided over the front surface.
5 is fixedly attached to the upper base body 51B with screws 79. Further, the lower surface side of the upper base body 51B is formed with a gentle notch 66 for escaping a part of the transport timing belt 22 which bypasses the outside of the end support pulley 12. On the other hand, at the upper end portion of the base body 51, a cartridge mounting portion 67 to which a cartridge 110 containing a supply component (workpiece 101) is detachably mounted is formed.

The cartridge 110 used in the present embodiment and the work 101 stored in the cartridge 110 will be described below. The cartridge 110 has a mounting portion corresponding to the cartridge mounting portion 67 at the bottom. 111 (see FIG. 7), and a plurality of (usually about 20,000) works 101 are stored inside in a loose state. Further, a shutter mechanism (not shown) is provided in the opening portion of the mounting portion 111, and when the slide knob 112 provided on the side surface of the shutter mechanism is slid, the opening portion can be freely opened and closed. There is. The cartridge 110 is a commercial product.

On the other hand, the work 101 is a chip capacitor in the case of this embodiment, and the work 101 has a vertical dimension t1 of approximately 0.4 mm and a horizontal dimension t2 as shown in FIG.
Is 0.8 mm and the length t3 is 1.5 mm. It should be noted that any other work may be used in the implementation.

Next, the first small chamber 54 communicates with the cartridge mounting portion 67 and has a large depth d1 (see FIG. 8). On the other hand, the second small chamber 55 is formed below the first small chamber 54 and communicates with the first small chamber 54. Depth d2 of this second small chamber 55 (see FIG. 8)
Is larger than the vertical dimension t1 (see FIG. 24) of the workpiece 101 and smaller than the horizontal dimension t2 (see FIG. 24), that is, the condition of (t1> t2) is satisfied. Further, an inclined guide surface (guide path) 81 is formed between the first small chamber 54 and the second small chamber 55, and when the work 101 is loaded into the first small chamber 54 from the cartridge 110. In addition, the guide surface 81 can be slid and easily guided to the second small chamber 55 side. In addition, in this embodiment, the first small chamber 54 and the second small chamber 55 are
The surface of each of the guide surface 81 and the guide surface 81 is provided with a satin pattern so that the work 101 is unlikely to stick to it.

The pushing-up piece guide groove 56 is provided in the second small chamber 5.
The lower side of the second small chamber 55 is formed so as to communicate with the second small chamber 55 and extend in the vertical direction, and the lower surface of one side of the second small chamber 55 is inclined toward the pushing-up piece guide groove 56. It is formed as an inclined surface 55a. A plate-shaped push-up piece 64 having a relatively wide width is accommodated in the push-up piece guide groove 56 so as to be vertically reciprocable by being guided by the push-up piece guide groove 56. When the push-up piece 64 is moved to the lower end side, the upper end surface 64a is provided such that the upper end surface 64a is arranged at a position substantially corresponding to the lower end of the inclined surface 55a, and the upper end surface 64a is provided on the inclined surface 55a. The workpiece 101 is slightly inclined toward the side, that is, the component guide groove 57, so that the work 101 can easily move toward the component guide groove 57. Also,
The thickness on the upper end side of the push-up piece 64 that is inserted into the first small chamber 54 and the second small chamber 55 is the vertical dimension t1 of the workpiece 101.
It is formed substantially equally.

In the component guide groove 57, the inlet 57a located on the upper end side communicates with the push-up piece guide groove 56 and the second small chamber 55, mainly as shown in FIGS. An outlet 57b located on the lower end side is opened at a lower corner portion of the upper base body 51B corresponding to the belt guide groove 23. Then, from the entrance 57a to the exit 5
In the process of reaching 7b, the component guide groove 57 is twisted by about 90 degrees. That is, at the entrance 57a, the work 1
In 01, the upper surface 101a faces outward, the direction is gradually changed until it slides in the component guide groove 57 and reaches the portion of the outlet 57b, and at the portion of the outlet 57b, the side surface 101b.
Is facing outward. Further, as shown in FIG. 15 as a cross-sectional view taken along the line BB of FIG. 14, the gap on the side closer to the inlet 57a is such that the depth T1 of the component guide groove 57 is smaller than the height t1 of the work 101. The width T2 of the curved portion is larger than the depth T1 and twice the height t1 of the work 101, as shown in FIG. 16 as a cross-sectional view taken along the line CC in FIG. Less than depth
It is formed so as to satisfy t2, that is, the condition of (T1 <T2 <2 · t1). In addition, other parts are also (2 · t1)
It is formed with a size that does not exceed. Therefore, since the width T2 of the curved portion is formed to be large, the work 10 is not formed in the curved portion.
Since a large gap is formed between the work 101 and the work 101, when the work 101 is dropped, the work 101
The corners of the contact with the inner surface of the component guide groove 57 and get caught,
You will not be disturbed by the fall. Moreover, work 1
Since it is formed with a depth t2 smaller than twice the height t1 of 01, even if the work 101 is clogged at the exit part, the work comrades overlap and are double-fed, or the clogging is further promoted. You can prevent such things. Also,
On the side of the inlet 57a, the width (depth T1) is reduced so that almost no gap is formed between the workpiece 101 and the workpiece 101. Therefore, when the workpieces 101 are introduced, a plurality of workpieces 101 may simultaneously enter the component guide groove 57. As a result, there is no such thing as hindering smooth introduction.

18 to 22 are operation state diagrams of the base body 51. Therefore, the operation of the base body 51 will be described with reference to FIGS. 18 to 22. FIG. 18 shows a state in which the work 101 is not loaded into the first small chamber 54 and the second small chamber 55, and the pushing-up piece. 64 is also moved to the lower end and is in a standby state.

Next, when the work 101 is stored in the first small chamber 54, it slides on the guide surface 81 and the second small chamber 5 is moved.
5 falls by gravity into the second small chamber 55 and pushes up the piece 64.
The upper end surface 64a and the inclined surface 55a are inclined (see FIG. 19). Further, some of them may be dropped by gravity into the component guide groove 57. In addition, the second small chamber 55
The depth d2 of the workpiece 101 is larger than the vertical dimension t1 of the workpiece 101 and smaller than the lateral dimension t2, that is, the condition of (t1> t2) is satisfied, and thus the workpiece dropped into the second small chamber 55. 101 is arranged with the upper surface 101a facing outward.

Next, when the push-up piece 64 is pushed up, the work 101 is stimulated by the movement of the push-up piece 64, and the work 101 is guided to the component guide groove 57 by the inclination of the upper end surface 64a and the inclination of the inclined surface 55a. It is in a sliding state, and a rolling force is applied to a part of the work 101. Then, the workpiece 101 that coincides with the component guide groove 57 is dropped into the component guide groove 57 by gravity, and this slides in the component guide groove 57 toward the outlet 57b, and while changing its direction on the way, the side face 1 is formed at the outlet 57b.
01b is turned to the outside and is discharged.

When the push-up piece 64 is further raised and extends beyond the second small chamber 55 and into the first small chamber 54, the work 101 on the lower end side in the first small chamber 54 is pushed up. . At this time, the inclined upper end surface 64a of the push-up piece 64 comes out with a part in which the direction of the work 101 is aligned (see FIG. 21).

When the push-up piece 64 is further moved upward, the work 101 sandwiched between the side surfaces of the first small chamber 54 and the push-up piece 64 is agitated (see FIG. 22). In this case, since the push-up piece 64 is formed in a plate shape, the stirring is performed better than in the case where the pin-shaped member is vertically moved in the conventional structure. At this time, since the lifting force is applied to the push-up piece 64 via the coil spring 62 described above, an unreasonable force is not applied to the work 101, and the risk of damage to the work 101 is avoided. doing. Moreover, since there is a stirring action, the first small chamber 5
One of the workpieces 101 located inside 4 falls into the second small chamber 55.

Next, when the push-up piece 64 descends, the work 101 on the inclined upper end surface 64a of the push-up piece 64 descends into the second small chamber 55 as it is. Along with the work introduced from the small chamber 54, a large number of works 101 are introduced into the second small chamber 55. Then, when the push-up piece 64 returns to the state of FIG. 19, one cycle ends, and the same operation is repeated again.

In the small chamber forming body 3 thus constructed, the lower base portion 51A is housed in the third recess 7c and fixed to the base 2 with the screw 79. The lower base portion 51A has a long hole 68 (see FIG. 7) formed at a position corresponding to the long hole 18 on the base 2 side.
Is located at a predetermined position of the third recessed portion 7c, the long hole 18 corresponds to the long hole 68, and the support shaft 17 is inserted through the long hole 18 and the long hole 68. It can be fixed by tightening with screws 69 (see FIG. 3). Further, the small chamber forming body 3 attached to the predetermined position of the base 2 with the screw 67 and the screw 69 in this manner has the lower end where the outlet 57b of the component guide groove 57 is opened, as shown in FIG. The edge portion 3a is brought into contact with the conveyance timing belt 22 on the side of the end supporting pulley 12, and the outlet 57b thereof has a horizontal tangent line 70.
The conveyance timing belt 22 is arranged so as to be elastically lower than the above. This arrangement is the exit 57b
The vibration of the conveyance timing belt 22 in the portion of (3) is suppressed, and it contributes to the work 101 discharged from the outlet 57b being smoothly placed on a predetermined position of the conveyance timing belt 22.

In addition, after the small chamber forming body 3 is attached, the work guide member 71 and the work take-out stage member 72 are attached to the upper surface 2b of the base 2.

Of these, the work guide member 71 is disposed immediately adjacent to the front side of the small chamber forming body 3 and is formed in a groove shape on the lower surface side corresponding to the outlet 57b of the component guide groove 57. A tunnel portion 73 is provided. Then, the tunnel portion 73 is arranged in a state of being extended to immediately before the cutout portion 15, and is fixed to the upper surface 2b of the base 2 by a screw 74 screwed into the screw hole 2i (see FIG. 7). There is. The work guide member 71 passes through the inside of the tunnel portion 73 when the work 101 taken out from the component guide groove 57 onto the transport timing belt 22 is sent to the front surface 2f side by the transport timing belt 22. It prevents vibrations and contact from moving, and contributes to maintaining the posture and orientation.

The work take-out stage member 72 mounted on the upper surface 2b receives the work 101 sent by the carrying timing belt 22 through the tunnel portion 73 of the work guide member 71 by the slit portion 76. That is, it contributes to stop at that position and wait until it is picked up by vacuum suction by a pickup mechanism having a vacuum suction nozzle (not shown). Further, when the transport timing belt 22 is driven during this standby, it is possible that the workpiece 101 and the transport timing belt 22 in the standby state slip and the workpiece 101 is waiting on the transport timing belt 22. to enable. Therefore, when the surface of the conveyance timing belt 22 becomes dirty and the frictional force becomes large, the work 101 may be forcibly fed in the standby state and the alignment in the standby state may be broken. In order to do so, the cleaner mechanism 2
4 is provided to clean the surface of the transport timing belt 22,
It is very important to eliminate the friction caused by dirt.

Next, the overall operation of the component supply apparatus 1 thus constructed will be described. First, the mounting portion 111 is inserted into and engaged with the cartridge mounting portion 67 to mount the cartridge 110 storing the plurality of works 101 on the upper portion of the small chamber molded body 3, and the component supply device 1 is mounted on a mounting machine (not shown). The positioning pin 9 is used for positioning. Next, the slide knob 112 of the cartridge 110
Is slid to open the shutter mechanism of the cartridge 110. Then, as described above, the work 101 in the cartridge 110 is gravitationally dropped in the first small chamber 54 and the second small chamber 55 in a separated state, and a part thereof passes through the component guide groove 57 and exits. It is dropped onto the conveyance timing belt 22 from 57b.

Next, before the operation on the mounting machine side is started, the work 1 is placed on the work take-out stage member 72.
A preliminary setting operation for carrying 01 in advance is performed.
In this preliminary setting operation, the operator manually operates the operation lever 41
Is repeatedly pressed and released, that is, the operation lever 41 is repeatedly moved up and down. When the operation lever 41 is pushed down here, the lever 33 of the timing belt drive system 31a is rotated in the clockwise direction in FIG. 3 in conjunction with this, and the lever 49 of the small chamber forming body side drive system 31b is turned on. It is rotated counterclockwise. In this case, when the lever 33 is rotated in the clockwise direction in FIG. 3, the ratchet wheel 32 and the drive wheel are driven by the action of the first ratchet pawl 34, the second ratchet pawl 35 and the ratchet wheel 32 as described above. The support shaft 14 that rotates together with the side pulley 11 does not rotate. Therefore, the transport timing belt 22 does not rotate.

On the other hand, when the lever 49 is rotated in the counterclockwise direction, the slide plate 61 is pushed up by the lever 49, and this is transmitted to the spacer member 59 side through the coil spring 62, and the pushing piece 6 together with the pivot 58.
4 is pushed up into the first small chamber 54. As a result, as described above, the work 101 is placed in the first small chamber 54.
While being stirred inside, it is gravity-fallen into the component guide groove 57 and sent toward the outlet 57b. As a result, the works 101 in the first and second small chambers 54, 55 are sequentially fed into the component guide groove 57.

When the operation lever 41 is released, the tension of the coil spring 43 causes the lever 33 to rotate counterclockwise in FIG. 3 and the lever 49 to rotate clockwise. It And lever 33
3 is rotated counterclockwise in FIG. 3, the ratchet wheel 32 is rotated by two teeth in the same direction as the lever 33 (direction of arrow F in FIG. 3) by the first ratchet pawl 34.
Then, the drive pulley 11 and the support shaft 14 are rotated in the same direction together with the ratchet wheel 32, whereby the conveyance timing belt 22 is moved forward (in the direction of arrow G in FIG. 5) by an amount corresponding to the rotation of the ratchet wheel 32. Is rotated.

In this embodiment, the amount by which the conveyance timing belt 22 is intermittently fed by one operation of the operating lever 41 is about 2 times the length t3 (= 1.5 mm) of the work 101.
It is set to the number of pieces (2 × t3), that is, about 3 mm.
Therefore, the work 101 dropped on the conveyance timing belt 22 through the component guide groove 57 is the same amount as the conveyance timing belt 22 every time the conveyance timing belt 22 is intermittently driven, that is, about 3 mm. The workpiece take-out stage member 7 is passed through the inside of the tunnel portion 73.
Therefore, the work 101 is always present on the work take-out stage member 72.

On the other hand, when the lever 49 is rotated clockwise, the slide plate 61 is pushed down with the pivot 63 as a fulcrum. Then, the inner surface of the long hole 60 of the slide plate 61 is brought into contact with the spacer member 59, the spacer member 59 is forcibly pushed down together with the pivot 58, and the push-up piece 64 is also moved downward accordingly.

As a result, one cycle of the preliminary setting operation is completed. In this way, the works 101 are sequentially sent to the work taking-out stage member 72 side, and the first work 1
01 is the slit portion 7 of the workpiece take-out stage member 72
It is received inside 6 and abuts on the back of the slit 76. Then, under the preliminary setting state, this work 101
Slips on the conveyance timing belt 22 and enters a standby state. Then, the next work 101 is similarly arranged in the slit portion 76 following the previous work 101,
It goes into a standby state. In this way, a plurality of workpieces 10
When 1 is placed on the conveyance timing belt 22 in the standby state, the preliminary setting operation is ended, and the mounting operation by the mounting machine is started.

In the mounting operation by the mounting machine, in the preliminary setting operation, while the operator manually pushed the operation lever 41, the pick-up mechanism (not shown) descending from above the work take-out stage member 72. Is pressed by. This pickup mechanism has a work 1 at the bottom.
It has a vacuum suction nozzle for chucking 01. When the vacuum suction nozzle sucks the work 101 on the work pick-up stage member 72 and the pickup mechanism is lowered, the operation lever 41 is pushed down by this lowering. Next, the vacuum suction nozzle suctions the workpiece 101 by vacuum suction and raises it, and the workpiece 101 is mounted on a predetermined printed wiring board (not shown). Further, when the pickup mechanism is raised, the depression of the operation lever 41 is released.
Further, in this operation, the pick-up mechanism is the work 10.
Since the work 101 is sent onto the work taking-out stage member 72 at a speed twice as fast as picking up 1, the work 101 is taken out of the work taking-out stage member 7
It is possible to avoid causing the parts to run out on the upper part.

Further, in this way, the cartridge 110
Work 101 inside is supplied and goes to Cartrid 11
When the work 101 in 0 is gone, remove the empty cartridge 110 and replace it with a new cartridge 11
0 is mounted and the slide knob 112 is operated to open the shutter mechanism. Then, a new cartridge 11
The work 101 in 0 can be supplied in the same manner.

Further, when the component supply device 1 is removed and replaced with another component supply device, the old component supply device 1 is removed from the mounting machine, and the rear surface 2 of the old component supply device 1 is removed.
The top and bottom of the component supply device 1 are turned upside down with the e side slightly facing down. Then, the work 101 sent onto the transport timing belt 22 is returned to the inside of the first small chamber 54 by tracing the path in the reverse direction, and is also returned from the first small chamber 54 to the inside of the cartridge 110. And the cartridge 1
After returning to the inside of 10, the slide operation knob 112 is operated next to close the shutter mechanism, so that all the works 101 can be exchanged while being housed in the cartridge 110.

Next, in the case of supplying a workpiece 101 having a different size from the previous one, after the mounting screw 91 is removed from the support shaft 14, the conveying timing belt 22 is moved by the stroke of the operation lever 41 once. The ratchet gear 32 having a pitch driven by a length approximately twice as long as that of the work lever 101 is replaced, and if necessary, the stroke amount of the operation lever 41 is adjusted once, and the component guide groove 57 corresponds to the size of the work 101. The workpiece guide member disposed on the conveyance timing belt 22 is replaced with a member having a size corresponding to the size of the work 101. By doing so, the same component supply device 1 can be applied to several kinds of works having different sizes.

Therefore, according to the component supplying apparatus of the present embodiment, the damper 80 is provided between the drive pulley 11 and the base body 2, and the damper 83 is provided between the end support pulley 12 and the base body 2. A damper 86 is provided in the spring 43, and a damper 87 is provided between the lever 49 and the base 2 so that when the operation lever 41 side suddenly fluctuates, these dampers 80, 8
Since it can be attenuated by 3, 86 and 87, the work 101 placed on the conveyance timing belt 22 can be conveyed to a predetermined position (the work taking-out stage member 72) as it is.

In the structure of the above embodiment, the structure in which four dampers (80, 83, 86, 87) are provided at different positions is disclosed, but some dampers are combined without providing all of them. It does not matter if the structure is made up of the same. Further, although a structure in which a friction material made of felt or a spiral spring is used as the damper is disclosed, for example, as shown in FIG. 23, the oil damper 88,
89 is used to apply a load to the drive pulley 11 and the end support pulley 12, and the drive pulley 11 and the end support pulley 12 are caused to rotate stably.
May be rotated stably. That is, in FIG. 23, the gears meshing with the gears provided on the outer peripheral surfaces of the drive pulley 11 and the end support pulley 12 are provided on the outer peripheral surfaces of the oil dampers 88, 89, and the rotating parts of the oil dampers 88, 89 are provided.
