Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a loop-type shuttle feeder that receives and conveys products produced at high speed in accordance with the production speed.

BACKGROUND TECHNOLOGY For example, in press processing, products produced by a press are taken out from the press, transported by various conveying devices, inspected, and then loaded onto pallets and sent out.

By the way, as the conveyance device for conveying the product, a shuttle feeder as shown in FIG. 6 is used when the product is produced at high speed. The shuttle feeder places a traveling trolley 2 on a slide rail 1,
The traveling carriage 2 is configured to be moved back and forth by a drive means such as a drive belt 3.

The shuttle feeder has a traveling cart 2 waiting at one end A of a slide rail 1, and when a product is placed on the traveling cart 2, the driving belt 3 moves the traveling cart 2 at high speed to a point B. After taking out the product from the traveling trolley 2, move the traveling trolley 2 again to A.
The product is transported by moving it to the point.

Problems to be Solved by the Invention The shuttle feeder described above can move the traveling cart 2 at high speed, so it can follow even if the products are produced at a certain high speed. If you have to wait until the trolley 2 comes back and forth to point A, and it takes T seconds for the traveling trolley 2 to move from point A to point B,
The product loading interval required more than 2T seconds, making it difficult to improve productivity.

Means to Solve the Problem This idea consists of a slide rail that forms a rectangular closed loop, with running rails laid at four locations on the top surface excluding the corners, and a reciprocating movement between each corner of the slide rail using an appropriate drive means. A plurality of driving bodies having their upper parts projected above the slide rail, and a guide rail having the same shape as the above-mentioned traveling rail are laid on the upper surface, and are arranged at each corner of the slide rail and rotate within a range of 90°. It has a turntable, an outer frame, and a rotating body rotatably mounted within the outer frame, a holding frame for placing the product on the outer frame is attached, and a traveling rail or a guide rail is clamped on the lower surface of the rotating body. It is provided with rotating rollers, and is configured with a plurality of traveling carts that are placed on the slide rail and run while being pushed by the driving body.

Function: In this invention, the traveling carriage is stopped on the turntable at each corner of the slide rail, all the driving bodies are moved in synchronization, and part of the driving body is locked to the traveling carriage during the movement. All the traveling carts are moved onto the turntables at the next corners, and after the movement, the driving bodies are returned to their original positions, and the turntables are rotated to align the guide rails of the turntables with the traveling rails in the next direction of movement. In preparation for the next operation, the above-mentioned operation is repeated to circulate all the traveling carts intermittently from one corner of the slide rail to the next corner.

Embodiments Hereinafter, embodiments of this invention will be described with reference to the drawings. In FIGS. 1 and 2, 10 is a slide rail, which forms a rectangular closed loop, with running rails 11 and 1 on the top surface of the straight section excluding corners.
2, 13, and 14 are installed. Furthermore, drive belts 15, 16, 17, and 18 that are reciprocated are built into the linear portion of the slide rail 10, and each of the drive belts 15 to 18 has drive bodies 19, 20, 21, 22.
A portion of the driving bodies 19 to 22 is made to protrude upward from the groove 10a of the slide rail 10. All of the driving bodies 19 to 22 are configured to maintain a protruding state without falling down even if an external force is applied thereto, and to fall down when an external force is applied when returning. 2
3, 24, 25, and 26 are turntables installed at each corner of the slide rail 10, and a guide rail 2 having the same shape as the running rails 11 to 14 is provided on the top surface.
7, 28, 29, and 30 are installed. The turntables 23 to 26 are configured to reciprocate within a range of 90 degrees by a rotating device (not shown) built into the slide rail 10. 31,3
Reference numerals 2, 33, and 34 are running carts that run on the slide rail 10, and they all have the same structure.
As shown in the figure, the outer frames 31a to 34a and the outer frame 31a
~Rotating body 31b rotatably attached to 34a~
34b, and running wheels 3 rolling on the slide rail 10 are provided on both sides of the lower surfaces of the rotating bodies 31b to 34b.
5 and 35, and a running rail 11 is provided at the center of the lower surface.
-14 or guide rails 27-30 are provided. Also, the outer frame 31
Locking protrusions 37, 38, 39, 4 on which any of the driving bodies 19 to 22 locks at four locations on the periphery of a to 34a
0 is provided in a protruding manner, and a bridge-shaped holding frame 41 is constructed on the upper surface side. The locking protrusions 37 to 40 are formed so that the rotating bodies 31b to 34b are located above the turntables 23 to 26, respectively, when the driving bodies 19 to 22 pushing the locking protrusions 37 to 40 respectively move to the forward end. put. Further, a holding stand (not shown) that matches the shape of the product to be transported is detachably attached to the holding frame 41.

In the loop type shuttle feeder having the above configuration, the four traveling carts 31 to 34 stop at each corner of the slide rail 10, and the holding rollers 36 and 36 of the rotating bodies 31b to 34b are connected to the turntables 23 to 23, respectively.
It holds the upper guide rails 27-30. In addition, each turntable 23 to 26 has a guide rail 27 to
30 is arranged in a straight line with the traveling rails 11 to 14 in the next moving direction. When the driving belts 15 to 18 are driven and the driving bodies 19 to 22 move forward, the driving bodies 19 to 22 are locked to the locking protrusions 37 to 40 of the corresponding traveling carriages 31 to 34, respectively, and Move 34. Each traveling trolley 3
When the turntables 1 to 34 leave the turntables 23 to 26, each turntable 23 to 26 rotates 90 degrees, changes the orientation of the guide rails 27 to 30, and waits for the traveling carts 31 to 34 (see Fig. 4). reference). When the driving bodies 19 to 22 move to the forward end, the carriages 31 to 34 move to the next turntables 24 to 26 and 23, respectively, and the clamping rollers 36 and 36 of the carriages 31 to 34 turn to the waiting position. When the traveling carts 31 to 34, which stop while holding the guide rails 28 to 30, 27 on the tables 24 to 26, 23, stop, the turntable 2
~26 and 23 rotate 90 degrees and guide rails 28~3
0 and 27 to prepare for the next movement, and at the same time, the drive belts 15 to 18 are reversed to move the drive bodies 19 to 2.
2 is moved backward, and the right drive bodies 19 to 22 are moved to the traveling bogie 3.
4, return to the rear of the locking protrusions 40, 37-39 of 31-33. (Refer to Fig. 5) By repeating the above-mentioned operation, the traveling trolley 31~
34 is intermittently sent from corner to corner of the slide rail 10 and circulated. For example, at corner A of the slide rail 10, products are loaded onto a running trolley, at the next corner B, products on the running trolley are inspected, at the next corner C, products are taken out from the running trolley, and at the last corner, products are loaded onto the running trolley. In D, nothing is done and the empty running cart is left on standby.

Effects of the invention According to this invention, the traveling cart for holding and transporting the product is circulated while being intermittently fed to each corner of the slide rail in order, so it can travel to any corner of the slide rail with one feeding. The trolleys can be arranged, there is no need to move the traveling trolley back and forth, and products can be loaded in half the time compared to conventional methods, reducing processing time and significantly improving productivity. Furthermore, since the rotating body of the traveling cart rotates together with the turntable and the outer frame does not rotate, the posture of the product placed on the outer frame does not change at any position, and the product can be easily processed.
