Description

[Detailed description of the invention] Ru.

Conventionally, there are various devices such as parts feeders for aligning and feeding rod-shaped parts, but devices using parts feeders have the problem of requiring a large hopper space to accommodate the parts. For example, it does not exist as a device for alternately conveying rod-shaped parts of different sizes.

SUMMARY OF THE INVENTION An object of the present invention is to provide a feeding device for rod-shaped parts, which is capable of arranging and storing rod-shaped parts in a hopper with a small space, and which can alternately feed out parts of different sizes.

An embodiment of the present invention will be described in detail below with reference to the drawings.

Fig. 1 shows a perspective view of the overall appearance of the feeding device, in which reference numeral 1 denotes two hoppers arranged in parallel, and inside both hoppers 1.1 there are a large number of round rod-shaped parts a with different lengths and diameters.
is accommodated. As shown in Fig. 2, the bottom surface 1a of the hopper 1 is sloped low toward the front side (to the right in the drawing), and inside the hopper 1, a partition plate 2 is provided so that the bottom part communicates with the front and rear chambers IA, IB. It is divided into The upper part of the front wall 1b of the hopper 10 has an opening 3, and a hopper chute 4 is connected to the opening 3 and installed at a low (slanted) position forward. A discharge chute 6 on the outlet side which is one step higher is arranged in series, and a step portion 5 serving as a stopper is formed at the connecting portion of both chutes.

A slit hole 7 is formed at the front end of the bottom of the front chamber of the hopper, and a lid plate 8 which moves up and down inside the hopper 1 in contact with the inner surface of the front wall of the hopper 1 is exposed through the slit hole 7. Therefore, when the lifter plate 8 moves up inside the hopper 1, it is pushed up by placing one rod-shaped part a on its upper edge 8a, and when the lifter plate 8 reaches the upper limit as shown by the imaginary line, the rod-shaped part a rolls into the hopper sheet 4 from the opening 3 and is stopped at the step 5.

Therefore, the rod-shaped parts a are stocked into the chute 4 one after another by the repeated lifting and lowering operations of the lifter plate 8. Note that the lifter plate 8 has a wall thickness similar to that of the rod-shaped part a.
It has a dog-shaped radius, and the upper edge 8a is a sloped edge that slants downward toward the front.

Further, in the embodiment of the present invention, the two hopper lifter plates 8 are operated simultaneously by a sliding cylinder device 9. The cylinder device 9 is supported by a support frame 10 as shown in FIG. Tin rockets 13 installed at the top of the other side
Hang the chains 14a and 14b on the chains a and 13b, and connect one end of each chain 14a and 14b to the
5a and 15b, and the other end is attached to the slide shaft 16 so as to be movable up and down.
, 17b, and this block 17a
, 17b, respectively, with the lifter plates 8 attached. With the above configuration, when air is supplied from the upper intake port 18a, the cylinder tube 12 moves upward due to reaction, and at the same time, the tin rockets 13a, 13b rotate forward, and the lifter plates 8, 8 rise together with the slide blocks 17a, 17b. . Next, when air is sent through the lower intake port 18b, the cylinder tube 12 moves downward and at the same time,
13a and 13b are reversed, and the slide block 17
The lifter plates 8, 8 are lowered together with a, 17b. By using the cylinder device 9 configured in this manner, a large lifting motion of the lifter plate 8 can be obtained with a small stroke of the cylinder tube 12.

A push-up plate 20 is provided at the bottom of the hopper chute 4 to move the bar-shaped parts a in the front row protruding from the stepped portion 5 to the discharge tray by operating a cylinder 19. A conveyor 21 having a V-shaped cross section is arranged at the exit of the discharge sheet, and this conveyor is connected to a support stand 22.
The rod-shaped parts a on the conveyor 21 are vibrated by, for example, a vibration generator 23 mounted on the conveyor 21 and transported to another process by animal movement. In addition, 24a,
Reference numeral 24b denotes a light emitting element and a light receiving element of a detector arranged across the entrance of each hopper chute 40. When the hopper sheet 4 is full of rod-shaped parts, the receiving element 24b'
The incidence of the light -"- is blocked, and the operation of the cylinder device 9 is stopped.

Next, the operation of the conveying device of the present invention will be explained.

When the lifter plate 8 is raised by the operation of the cylinder device 9, the edge 8a of the lifter plate 8 pushes up one bar-shaped part a to the opening 3 of the hopper, and this pushed-up bar-shaped part is moved to the opening 3 as well as to the hopper chute. 4 and is stopped when it hits a step 5 which is the starting end of the discharge chute. The parts in the hopper are sent out into the hopper chute 4 one after another by the repeated lifting and lowering operations of the lifter plate 8. The most advanced rod-shaped part a in the hopper chute 4 is then moved onto the discharge chute 6 by the push-up plate 20 which is moved upward by the operation of the cylinder 19, rolls on the seat and falls onto the conveyor 21, This fall.

The finished parts are transported to the next process section by a conveyor.

In addition, in the above embodiment, since the rod-shaped parts housed in the two rods <-1, 1 can be sent out into the seato, rod-shaped parts with different lengths and diameters can be conveyed one by one alternately. It can be supplied to the process.

In addition, in the embodiment, two hoppers are provided, but the number of hoppers can be freely incorporated as required.Also, the lifter plate 8 may have a different wall thickness depending on the diameter of the rod-shaped parts. It is also possible to freely change the .

In addition, the hopper 1 has two parts in the left and right side walls as shown in Fig. 4.
Two guide plates 25, 25 are arranged, and adjusting screw rods 26, 26 are screwed into the hopper side wall, and the screw tips are rotatably connected to seat seats 25a, 25a provided on the guide plate 2-)y25. By doing so, the interval between the guide plates 25.25 can be freely adjusted by rotating the adjusting screw rod 26.26, and thereby rod-shaped parts of different lengths can be accommodated.

As explained above, according to the present invention, rod-shaped parts can be arranged and stored in a hopper with a small space, and a plurality of hoppers can be arranged in parallel, and rod-shaped parts with different lengths and diameters can be stored in each hopper. By doing so, rod-shaped parts having different sizes can be alternately conveyed to the sheet one by one. Furthermore, since the inside of the hopper is divided into front and rear chambers 1a and 1b by a partition plate whose lower part communicates with each other, the rod-shaped parts in the rear chamber are supplied to the front chamber in an amount that does not interfere with the operation of the lid plate 8. Therefore, the vertical movement of the lifter plate will not be hindered, the bar-shaped parts will not be obliquely caught in the opening, or the lid plate will not bite the bar-shaped parts. The parts sent into the hopper chute are temporarily stopped at the stepped portion and then sent out to the discharge chute by the push-up plate, so the parts can be sent out to the chute. This has the advantage of being able to reliably send each piece of paper to the conveyor.
