(Prior Art) The present applicant has conventionally proposed a configuration in which radial electronic components are transported by a pallet that travels intermittently in a horizontal plane. In this case, only radial electronic components were transported on pallets.

(Problems to be Solved by the Invention) Recently, however, there has been a demand from consumers for an automatic insertion device that can insert both radial electronic components and 7-axis electronic components in one device, and also requires a faster insertion speed and There is a growing demand for an improved insertion rate, and for this reason we are considering a configuration in which a pallet for transferring electronic components can be used to transfer both radial electronic components and 7-axis electronic components! It has been done.

(Means for Solving the Problems) In view of the above points, the present invention provides a driving wheel, a driven wheel spaced apart from the driving wheel by a predetermined distance, and a belt-wrapping portion of the driving wheel and the driven wheel. a feed belt that is provided between each of the tape portions of the axial electronic component chain and conveys the tape portion in contact with the tape portion of the axial electronic component chain; a cutter mechanism that cuts the lead wire of the axial electronic component chain that is positioned in the lead positioning groove of the drive wheel; With a configuration including a push rod that raises the tip of the pallet-side component placement section that receives the axial electronic components separated from the axial electronic component series by the cutter mechanism toward the drive wheel side, seven axial electronic components can be removed from the axial electronic component series. It is an object of the present invention to provide an axial electronic component supply device that can separate components one by one and reliably transfer them to a pallet for electronic component transfer.

(Example) Hereinafter, an example of the axial electronic component supply apparatus according to the present invention will be described with reference to the drawings.

First, FIGS. 10 to 12 show an example of the structure of a pallet that can be used to transport both radial electronic components and axial electronic components. In these figures, a pallet 2 is fixed at a pallet body 3 to a chain 1 as an endless belt mechanism that runs intermittently in a horizontal plane, and a pallet for radial electronic components is mounted at a front position on the pallet body 3. A component holding section 4 is provided. This component holding part 4
The radial electronic component series 10A is held by cutting off the radial electronic component series 10A along the dashed line P so as to have one radial electronic component.

Further, a support stand 5 is fixed on the pallet body 3 at a rear position of the component holding section 4, and a component mounting section 6 for axial electronic components is pivotally mounted on the support stand by a bin 7.

This component mounting section 6 has a pair of arms 8, and these arms 8 have a V-shaped receiving groove for receiving the lead wire 17 of the axial electronic component 15 separated from the axial electronic component chain 10B as shown by the dashed line Q. 9 are formed respectively. Since the component mounting section 6 is pivotally supported by a pin 7 to the support stand 5, pushing the padding section 11 at the rear end causes the pair of arms 8 at the front end to lift up. In the normal transfer state, the support platform 5 is
It is regulated to be in a horizontal state in close contact with the Further, a leaf spring stopper 13 is attached to the bottle 7, and the leaf spring stopper 13 is biased by a spring 14 in a direction in which the tip thereof rises. However, the position of the leaf spring stopper 13 is restricted with the rear part in contact with the upper surface of the component placement section 6, and the tip end 13A of the leaf spring stopper 13 is located on the outside of each of the pair of arms 8 of the component placement section 6. As shown in FIG. 11, the lateral position of the tip of the lead wire 17 of the seven-wire electronic component 15 is regulated.

The axial electronic component supply device separates and supplies axial electronic components one by one from a series of axial electronic components to the pallet 2 as described above, and the details of its structure are shown in FIGS. 1 to 9. In these figures, an intermittent rotation drive shaft 21 and a rotation driven shaft 22 are supported at the lower end of the main body frame 20, a pair of drive wheels 23 are fixed to the drive shaft 21, and a pair of drive wheels 23 are fixed to the driven shaft 22. A driven wheel 24 is fixed. A feed belt 26 is stretched between the belt winding portion 25 of the drive wheel and the driven wheel 24. The drive wheel 23 also has a positioner 1lls28 in which a substantially square lead positioning groove 27 is formed, which corresponds to the electronic component array spacing of the axial electronic component series 10B, and as a result, the entry side guide is formed as shown in FIG. The part of the tape 16 of the axial electronic parts series JOB guided by "30" is driven in contact with the feed belt 26, and the part of lead #i17 is driven by the positioning part 28.
It is regulated by the lead positioning groove 27 formed in the.

As shown in FIG. 4, the entry side guide 30 has a hinge 3 at one end.
], and by removing the lock 32, the underwear of the axial electronic component series 10B can be removed very easily.

1. A driving air cylinder 33 is attached to the upper part of the main body frame 20, and a slider 34 that slides vertically along the main body frame 20 is connected to the piston rod of the air cylinder 33.

A plate cam 35 is fixed onto the stay 34. Further, an air cushion cylinder (combined with a compression spring) 36 is incorporated into the lower end of the slider 34, and the piston rod of the air cushion cylinder 36 serves as a pallet pushing rod 37.

A feed 7 check wheel 40 is fixed to the intermediate portion of the intermittent rotation drive shaft 21, and a feed pawl 41 and a return prevention pawl 42 are provided to engage with this, and further define the movement range of the feed pawl 41. Therefore, a feed pawl stopper 43 is fixed to the main body frame side. In addition, the feed claw 41 and the return prevention claw 4
2 are both biased by springs in the direction of engagement with the feed ratchet wheel 40. A lever 44, 45 is connected to the feed claw 41, and the link 45 is pivotally supported by a pin 59 on the side of the main body frame, and a ratchet/7-tooth feed roller 46 provided at the end of the link 45 is used to drive the link 45. The ratchet drive cam surface 47 of the plate cam 35 interlocked with the air cylinder 33 can be brought into contact with the ratchet drive cam surface 47 of the plate cam 35.

Further, near the lower end surface of the main body frame 20, a lead presser plate spring 48 is pivotally supported by a pin 49, as shown in FIG. The lead holding plate spring 48 is normally urged to the raised position by an extension spring 50, and a hook 51 is provided at the rear end. This hooking pawl 51 is normally biased in the ejecting direction by a compression spring.

Furthermore, as shown in FIG. 2, a cutter drive lever 52 is pivotally supported by a shaft 53 at the lower part of the main body frame, and a cutter movable force 54 is attached to the tip of the cutter drive lever 52. Further, a cutter driving roller 55 is provided at the upper end of the cutter driving lever 52. The movable cutter blade 54 is movable in contact with the outer surface of the positioning portion 28 of the drive wheel 23, and the outer surface of the positioning portion 28 constitutes a fixed cutter blade. The cutter driving roller 55 can come into contact with a cutter driving cam surface 56 of the plate cam 35 that is interlocked with the driving air cylinder 33.

Note that after the axial electronic component 15 is separated, the axial electronic component chain 116 is connected to the guide 60 and the feed belt 26 by the supports provided under the drive wheel 23 and the driven wheel 24, as shown in FIG. Hiro is caught between the two.

Next, the operation of the above embodiment will be explained. In the standby state, as shown in FIG.
1 and the return prevention pawl 42 are also in the state shown in FIG. ing. Therefore, in this state, the first axial electronic component series 10B can be easily mounted.

Now, from this special effects state, air pressure is supplied to the air cylinder 33 according to instructions from the main unit NC, and this piston rod begins to descend.
7, the ratchet feed rotor 46 comes into contact with the link 45, 44, which moves the feed pawl 41 as shown in FIG.
is driven until it comes into contact with the feed pawl stopper 43. This ratchet action causes the drive wheel 23 to rotate by a predetermined amount, and the axial electronic component 15 comes to a predetermined position (a position where it can be cut by the cutter mechanism).

Furthermore, due to the extending movement of the air cylinder 33, the pallet pushing rod 37 comes into contact with the stopper part 11 of the component placement section 6 on the pallet 2 side, as shown in FIG. 7, and pushes up the tip of the component placement section 6. .

As a result, as shown in FIGS. 7, 8, and 12, the V-shaped receiving groove 9 of the component mounting portion 6 is aligned with the drive wheel 2.
The lead wire 17 of the axial electronic component 15 positioned by the lead positioning groove 27 on the third side is almost engaged with. At this time, the upward movement of the pallet-side component placement section 6 stops when it comes into contact with the pallet stopper 57 on the main body frame side, and thereafter the slider 3 due to the extension movement of the air cylinder 33
4 is absorbed by the air cushion cylinder 36.
It will be done.

Then, as a result of the subsequent downward movement of the slider 34, the cutter drive cam surface 56 of the plate cam 35 is brought into contact with the cutter drive roller 55, and as a result, the cutter drive lever 5
2 rotates clockwise to cut the lead wire 17 of the axial electronic component chain between the outer surface of the drive wheel side positioning part 28, which becomes the cutter fixed blade, and the cutter movable blade 54, and as a result, the axial electronic component chain is cut off. Part 15 is Pallet I
11 The receiver is passed to the V-shaped receiving groove 9 of the component placement section 6.

It should be noted that during cutter operation, the tip 113A of the leaf spring stopper 13 on the side of the ball F is located at the lower surface of the cutter movable force 54.
Although it is located as shown in the figure, since it is only urged in the upward direction by the spring 14, it does not interfere with the operation of the movable blade 54, and after the cutter operation is completed,
As the tip of the component placement section 6 descends, it is positioned in the lateral direction of the component placement section 6 so that the position of the tip of the lead wire of the seven-wire electronic component 15 can be regulated.

After the extension operation of the air cylinder 33 is completed, the air pressure to the cylinder is cut off by the timer setting of the main body NC, and the air cylinder 33 starts the retraction operation. As a result, the piston rod begins to rise, and first the movable cutter blade 54 returns to its original position.
Subsequently, the hook at the lower end of the slider 34 engages the member 58 with the hook 51 at the rear end of the lead presser plate spring 48, and as a result of this hook, the tip of the lead presser plate spring 48 begins to fall into the receiving groove 9 of the component placement section 6. Lead wire 1 of the upper axial electronic component 15
Hold 7. During this time, the air cushion cylinder 36 returns from the compressed state to its original state, and when the air cushion cylinder 36 is expanded, the pallet push-up rod 37 rises and the pallet side component placement section 6 returns to its original state. begins to return to. At this time, the lead holding plate spring 48 slightly bends while holding down the lead M17 of the axial electronic component 15, and lowers its tip in synchronization with the component placement section 6 as shown in FIG. 58
is disengaged from the hooking pawl 51, and returns to the original standby state.

During this time, the feed pawl 41 that engages with the feed ratchet wheel 40 also returns to its original standby state.

As a result of the above operation, the lead #117 is engaged with the V-shaped receiving groove 9 of the component placement component 6 on the pallet 2, and the position is regulated by the leaf spring stopper 13, as shown in Fig. plS11. The parts 15 will be supplied to the pallet 2 side.

According to the above embodiment, the following effects can be achieved.

(1) Since the purpose is achieved by the reciprocating movement of the air cylinder 33, the mechanism is simple, no complicated rotary solenoids are required, and the cost is low and power consumption is low.

(2) Since the cutter mechanism has a lever structure, the space at the tip is minimal, and electronic components can be transferred onto the pallet 2 with a short stroke.

In addition, there is no need for extra guides, chutes, etc., and there is no switching operation (and direct cutting is highly reliable).

Furthermore, since the lead wire portion of the axial electronic component chain is cut, the reliability of the cutter operation is higher than that of cutting the tape portion.

(3) Since the drive wheel 23 does not need to cut while rotating, the positional relationship with the pallet 2 is clear, making it easy to align the two, saving time and improving the reliability of the delivery. do.

(4) Before the cutter operation, the V-shaped receiving groove 9 of the part mounting section 6 on the banitt side is inserted into the lead positioning groove 27 of the drive wheel 23.
Since the axial electronic components are in an overlapping state, the distance that the axial electronic components fall due to the cutter operation is very small (almost negligible), and when the tip of the component placement section 6 descends, it is synchronized with this. Since the lead holding plate spring 48 descends while holding down the lead wire 17, in the operation of cutting off the seventh axial electronic component 15 from the axial electronic component series 10B and supplying it to the component placement section 6 of the pallet 2, the axial electronic component 15 is The lead wires are never left in the open state, and the delivery to the pallet 2 is extremely reliable, and high-speed operation is possible.

In addition, the pallet side plate spring stopper 13 also prevents the axial electronic component 15 from interfering with the operation of the cutter.

A feed belt that is provided in the distance from the wheels and that contacts and transports the tape portion of the axial electronic component chain, and a cutter that cuts the lead wire of the axial electronic component chain that is positioned in the lead positioning groove of the drive wheel. The mechanism includes a mechanism and a push rod that moves the tip of the pallet-side component placement portion that receives the axial electronic components cut from the axial electronic component series by the cutter mechanism upward toward the drive wheel side.
Seven axial electronic components can be separated one by one from the axial electronic component chain and reliably delivered to a pallet for electronic component transfer. Further, the configuration is suitable for increasing the supply speed.
