Abstract

PURPOSE:To shorten the necessary time by retracting the belt conveyors at the opposite sides of passing mechanism then lifting the passing mechanism loaded with material and transferring the material to the passing mechanism. CONSTITUTION:When a passing mechanism 3a will mount a material 2 received from first carry path 1 then rotate and stop to lift in the arrow direction B, the belt conveyors 3b', 3b'' of the passing mechanism 3b will retract to the positions E, F which will never cause hindrance against the lifting, and upon lifting of the mechanism 3a to the position of the mechanism 3b, move in the direction D and set to the position for supporting the material 2 thereafter the mechanism 3a will start lowering while the mechanism 3b will rotate in the arrow direction C thus to transfer the material 2 to second carry path 6.

Description

TECHNICAL FIELD The present invention relates to an article conveyance device, and particularly to a mechanism for transferring articles between conveyance paths of a physical distribution device.

In a logistics device, it may be necessary to automatically move articles from one conveyance path to another conveyance path.

At this time, it is the transfer mechanism that automatically transfers the articles between the trap conveyance paths, and the present invention relates to an article transfer mechanism that reduces the cycle time of the transfer operation and improves processing efficiency. It is.

PRIOR ART FIGS. 1(a) to 1(e) show the process of transporting operation by a trapping conventional transfer mechanism. First, in FIG. 1(a), among the articles 2a, 2b, and 'lc conveyed from the first conveyance path IVc in the form of an endless belt conveyor, the frontmost article 2a is transported from the first conveyance path IVc in FIG. 1(b). From the path 1, the material is transferred to a transfer mechanism 3 in the form of a horizontal belt conveyor capable of upward movement.

The articles 2a and 2b are transferred to the transfer mechanism 3 and the front d[) first
It is conveyed to a predetermined position by the conveyance path 1.

When this is confirmed by the position detection means 5 and 4, the first transport path 1 and the transfer mechanism 3 stop rotating. 1st
Figure 1c) Transfer 1lLl receiving article 2a at l'c
! The mechanism 3 moves to the same position as the second conveying path 6 of the belt conveyor type, which is different from the first conveying path 1 in the diagonal position 1 to 1, as shown in FIG. 3, the article 2a is transferred from the transfer mechanism 3 to the second conveyance path 6.
It will be transferred to. FIG. 1(e) The article 28 is placed in the second
The transfer mechanism 3 that has finished loading the transport path 6 \# stops rotating again and returns to the original position of the transport path 1 of il. In this process, the states in FIG. 1(a) and FIG. 1(e) are the same, and the operations in FIG. 1(b) to FIG. 1(e) are repeated as the overall transfer operation. Here, while the transfer mechanism 3 is rising and being transferred to the second conveyance path 6, the Ml conveyance path 1 is stopped 1- when the next article 2b comes into contact with the position detection means 4. must be maintained. In such a conventional transfer mechanism, since each stroke is performed in a 7-kensial manner, the cumulative time required for each stroke becomes the required time for one cycle, which has the disadvantage that it takes too much time for 5 cycles.

OBJECT OF THE INVENTION The present invention provides a transport device that can shorten the time required for one cycle by overlapping some of the steps in one cycle of the transfer operation, The purpose is to provide a loading mechanism.

Structure of the Invention To achieve the object, the transfer mechanism of the present invention includes a receiving mechanism that receives the article at the exit of the first conveyance path and transfers the article to the second conveyance path, and and a delivery mechanism that picks up the loaded articles and transfers them to the second conveyance path.

Preferred embodiments of the invention Next, embodiments of the present invention shown in the drawings will be described.

Figures 2(a) and 2(b) show an embodiment of the transfer mechanism according to the present invention. The transfer mechanism in this embodiment is composed of a receiving mechanism 3a and a delivery mechanism 3b. Receiving mechanism 3a
is a belt which is rotated in the direction of arrow A in FIG. 2(b) by a drive source (not shown) and moves up and down in the direction of arrow B from position 1 of the first conveyance path 1 to the second conveyance path 6. It's a conveyor. The delivery mechanism, indicated by reference numeral 3b, is a symmetrical structure capable of rotating in the direction of arrow C in FIG. The delivery mechanism 3b is located at the same height as the second conveyance path 6, and the receiving mechanism 3a receives the articles received from the first conveyance path 1. When 2 is loaded 1- and the rotation is stopped in the direction of arrow 11, each belt conveyor 3b of the delivery mechanism 3b
', 3b'' are located at positions that do not hinder the lifting of the article 2.

F, and when the receiving mechanism 3a rises to the position of the delivery mechanism 31), it moves in the direction of the arrow to a position where it can support the article 2 and does not interfere with the receiving mechanism 3a (solid line position) It is set to come to . When the article supporting position of the delivery mechanism 3b is set, the receiving mechanism 3a immediately begins to descend. Further, the delivery mechanism 3b transfers the article 2 to the second conveyance path 6 by rotating in the direction of arrow C.

FIGS. 3(a) to 3(e) show the order of transport operations when the transfer mechanism according to the present invention is used. In addition, Fig. 3(a) to (
In the example of e), the horizontal movement force direction of the transfer mechanism 3b is as shown in Fig. 2(a).
), it moves in a direction parallel to the second conveyance path 6. First, in FIG. 3(a) VC, the delivery mechanism 3b is retracted from the article receiving position in the direction D' VC, and the resulting articles 2a, 2 are conveyed by the first conveyance path 1.
Among items b and 2c, item 2a is placed in the first position in the state shown in Fig. 3(b).
1ilI! from the conveyance path 1 to the receiving mechanism 3a! be done. The articles 2a and 2b are transported through the first transport path l and the receiving mechanism 3a.
When the position detecting means 5.4 confirms that the paper 91 has been transported to a fixed position, the first transport path 1 and the receiving mechanism 3a stop rotating.

In FIG. 3(c), the receiving mechanism 3a that has received the article 2a at V rises to the height position of the delivery mechanism 3b. In FIG. The transfer mechanism 3b moves from the previous retracted position to a position lined up with the receiving mechanism 3a. When the transferring mechanism 3b moves to this position in FIG. 3(e), the receiving mechanism 3a
begins to descend, and upon completion of the descent, receives the next article 2b from the first conveyance path 1.

At the same time, the delivery mechanism 3b transfers the article 2a to the second conveyance path 6 by rotating the belt, and returns to the above-mentioned retreat position when the transfer is completed. That is, the state shown in FIG. 3(b) is reached. As described above, in the transfer state using the transfer mechanism of the present invention, the steps shown in FIG. 3(b) to FIG. 3(e) are repeated.

The transfer sequence of each step in the detailed description of the invention cannot be made extremely fast in the case of fir + d objects or easily crumbled objects, but in the case of movement of only the mechanical part without transfer of the object, the speed can be increased. It can be done quickly. Assuming that the required time for each process involving the movement of goods is 5 seconds, the process that does not involve movement of goods, that is, the transfer mechanism 3 in Fig. 1(e) and the time required in Fig. 3(e) K
The drop-down time of the receiving mechanism at Then, one cycle with the conventional 18-mount mechanism is 1
7 seconds, whereas in the case of the transfer mechanism according to the present invention, it takes 13 seconds, which is a significant time reduction.

As explained above, according to the present invention, the processing speed can be greatly improved by adding a simple mechanism.
