Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-part feeder which is most suitable for mounting as an accessory of a synthetic resin injection molding machine and is most suitable for supplying insert parts.

[0002]

In injection molding of synthetic resin, one machine has a plurality of molds. When supplying insert parts to each mold, the parts should be supplied all at once. Although it is possible to improve the production efficiency, it is economically and mechanically to place the robots facing each other because each die is currently supplied by a robot. However, a robot requires a large number of insert parts to be arranged in advance on a pallet, and a device for arranging them in a line is also required.

The present invention is to solve the above problems, and its main purpose is to be able to supply insert parts to each mold at once by one device, but it is not limited to supplying parts to an injection molding machine. In the same manner, it is to develop a multi-component supply device that can be applied to an assembling machine that similarly needs to supply a plurality of the same parts all at once.

[0004]

According to the present invention, a pallet in which a plurality of component storage portions are lined up at a tip opening of a chute drawn out from a parts feeder is transferred from a departure station by a transfer means. The portion intermittently feeds in the direction opposite to the chute opening, and is provided so as to be capable of reciprocating to the delivery station provided on the extension line of the feeding direction, and each of the pallets located at the delivery station is located in the station. It is characterized in that a distribution means is provided for sending out the parts from the parts storage section.

[0005]

[Function] The parts fed by the chute of the parts feeder are received in the first part storage part of the pallet, and then the pallet is moved forward so that the second part supply part next faces the chute port. Then, after receiving the components in the second component supply unit, the components are sequentially received in the same manner to the third component supply unit, all the component supply units receive the components, and when the pallet reaches the delivery station, the distribution means The parts are sent all at once.

The above-mentioned transfer means is constructed such that the cylinder is driven forward by continuously driving the pallet forward by the cylinder, stopping the pallet by the notch stopping means, and providing a spring for assisting the forward feeding of the pallet. On the other hand, it is not necessary to give control to stop intermittently, and it is possible to surely sequentially face each of the component storage portions provided on the pallet to the chute opening from the parts feeder.

Further, the distribution means provided in the delivery station is constituted by a nozzle for injecting air facing each component storage portion of the pallet and a supply hose for transferring the dispensed components, so that each component is aimed at. Can be supplied all at once.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment according to the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, a chute 2 for feeding parts W from a part feeder 1 is inclined so that a tip opening is lowered. The pallet is provided with the escapement 3 and the posture changing unit 4 in the vicinity of the tip opening of the chute 2, and reciprocates continuously in the direction orthogonal to the chute 2 continuously to the tip opening of the chute 2. 5, a plurality of component storage portions 6 each having a groove for receiving one component W sent from the chute 2 on the upper surface of the pallet 5 are provided at intervals along the feeding direction of the pallet 2, specifically, 4 are provided. Moreover, the front and rear ends of the component storage part 6 are the pallets 5
It is open on both sides. Further, the upper surface of the pallet 2 on which the component storage portion 6 is provided is inclined similarly to the inclination of the chute 2.

The escapement 3 is a shoot 2
It is of a pushing rod type in which a cylinder is inserted from the side, and sends one component W to the posture changing unit 4.

The posture converting section 4 is unnecessary if the parts are not divided into front and rear parts, and is attached in the case of parts having front and rear parts, depending on the shape of the parts.
The device shown in the figure adopts a system that uses a rotating disk and a light-transmissive sensor that detects the front and rear parts of a component.If it is transferred normally, it will pass through the disk as it is and reverse. If there is, the disk is rotated half a turn and sent out.

Therefore, the parts W are sent out from the parts feeder 1 to the chute 2, and are fed in the chute 2 without interruption due to a drop and air blowing.

Then, the pallet 5 is advanced from the departure station 7 and the preceding component storage section 6 is moved to the chute 2.
It stops at a position opposite to the tip end of the second part, receives one part W, and then moves forward again.
When it reaches the delivery station 8 provided on the extension line of the pallet 5 for moving forward, the operation of stopping again at the position facing the tip end of the By means of the means 9, the respective parts W are dispensed at once and distributed and supplied to the intended positions. After that, the pallet 5 is returned to the departure station 7 all at once, and during the returning operation, the escapement 3 controls the feeding of the parts W to be stopped. By the way, since the upper surface of the pallet 5 is inclined as described above, the received component W will slide down from the lower opening, but to prevent this, the departure station 7 of the pallet 5 is prevented. A supporting wall 10 covering the lower side surface is provided with a sliding surface having a low coefficient of friction along the traveling path from the to the delivery station 8.

As described above, the pallet 5 is crushed and forwardly transferred, and its transfer means 11 engages the slide rail 12 with the cylinder 13 for pneumatically driving the pallet 5. Further, a spring 14 is provided which is connected to the pallet 5 and urges the pallet 5 in a forward direction, and a notch stopping means 15 is provided so as to face the pallet 5.

The notch stopping means 15 has a plurality of teeth on the side surface of the pallet 5 having a rising surface from the lower position of the inclined surface like saw teeth, specifically, for one of the four component storage portions 6.
Linear ratchet 16 in which a large number of five teeth are arranged in a row at an interval of the same pitch as the arrangement pitch P of each component storage unit 6
Is fixed along the longitudinal direction of the pallet 5, and on the other hand, the pair of engaging claws 17 and 17 are opposed to the linear ratchet 16.
Are provided so as to be alternately moved forward and backward by cylinders. The distance between the engaging claws 17 is specifically one of the arrangement pitches P of the component storage portions 6.
The pallet 5 is ½ of the arrangement pitch P of the component storage parts 6 by providing a pitch plus a half pitch and alternately engaging the pair of engaging claws 17 with the teeth of the linear ratchet 16. It is designed to be transferred pitch by pitch. The operation of alternately locking the pair of engaging claws 17, 17 to the linear ratchet 16 is such that one engaging claw 17 is locked as shown in FIGS. 3 and 4. From the state in which the other engaging claw 17 is retracted, first, the retracting engaging claw 17 is advanced to abut the inclined surface of the teeth of the linear ratchet 16, and then the engaging claw already locked. The pallet 5 is controlled so as to move backward, and the pallet 5 advances by a half pitch by the pressing force of the transfer means 11 during the locking and releasing in this way, and again the two engaging claws 17, 1 are engaged in the same manner as above.
Since the pallet 5 advances by a half pitch by moving the 7 forwards and backwards and locking and releasing it, the engaging claws 17 already locked
One pitch is sent in one round trip.

Further, as described above, the engaging pawl 17 is locked to the linear ratchet 16 to stop the movement of the pallet 5, but even during this stop, the cylinder of the transfer means 11 continues to drive forward. However, if the driving force is large, the crush stop means 15 may be destroyed or the cylinder may be damaged, but by setting the driving force small, there is no problem and it can withstand long-term use. Moreover, the control means for stopping and positioning the cylinder is not required, which is advantageous in terms of the configuration. However, if the driving force is small, reliable transfer of the pallet 5 cannot be expected,
To compensate for this, the spring 14 is provided as described above.

The transfer means 11 and the chopping stop means 15 described above
By feeding the pallet 5 by half pitches, the pallet is not accelerated and each component storage portion 6 is surely brought into contact with the mouth of the chute 2 one after another.

In this way, the component W is inserted into each component storage section 6 and the pallet 5 is delivered to the station 8. Here, the last tooth of the linear ratchet 16, specifically, the fifth tooth is provided. Although the engaging claws 17 are locked to the teeth of the distribution unit 9, the distribution means 9 provided in the delivery station 8 individually faces the respective component storage portions 6 and injects air, and the component storage units 6. And a supply hose 19 for delivering the part W delivered from the section 6.

More specifically, the pallet 5 is inserted into the delivery station 8 along the supporting wall 10, but the blowing block 20 is provided on the side opposite to the supporting wall 10 and the side surface of the pallet 5 slides. The nozzles 18 are movably fixed in close contact with each other, and the nozzles 18 are built in the blow block 20 so as to face the respective component storage portions 6, and the blow block 20 is provided with ports 21 communicating with the nozzles 18. ,
The air supply hose is connected to each port 21.

Delivery station 8 of one support wall 10
A through hole 22 that faces each component storage portion 6 in a portion corresponding to
A discharge shutter 23 that opens and closes all the openings of each through hole 22 at once is provided by a cylinder (not shown) so as to move up and down. On the opposite side of the support wall 10 from the discharge shutter 23, the through holes 22 of each through hole 22 are provided. The supply hose 19 is connected so as to extend from the mouth.

It should be noted that defective parts may happen to be mixed in the parts to be put into the parts feeder 1, and it is necessary to detect and eliminate them at an early stage. As a means thereof, at a portion of the support wall 10 facing the mouth of the chute 2,
A discharge shutter 24 that blocks the opening of the component storage unit 6 is installed so as to open and close in the vertical direction by a cylinder.
On the other hand, by opening the shutter 24 according to a signal detected as a defective product by the search in the posture conversion unit 4,
Parts that are determined to be defective are discharged outside the pallet. Further, when the discharge shutter 24 is driven, the feeding operation of the pallet 5 is stopped, and the next non-defective component is received in the component storage unit 6 and then is controlled to move.
