[Operation] A pair of left and right rotor plates is formed in a polygonal shape having a side length corresponding to a distance between joints of links forming the endless link belt, and the endless link belt is wound around these rotor plates. The endless link belt is rotationally driven by being mounted and rotating a pair of disk-shaped rotors synchronously and in phase.

Since the disk-shaped rotor has a polygonal shape, an endless link belt constituted by links having a large unit length can be smoothly and reliably transferred by a rotor plate having a smaller size than a conventional disk-shaped rotor.

The object to be transferred having a width wider than the distance between the joints at both ends of the gripping link can be transferred.

[First Embodiment] Fig. 1 is a plan view showing a schematic configuration of a first embodiment of the apparatus of the present invention, and Fig. 2 is a perspective view showing a main part of the same apparatus.

A pair of left and right square rotor plates (11) forming a square of the same size are rotatably supported on a vertical rotating shaft (12), respectively, and a number of gripping links (13) and connecting links (14).
Are wound around a pair of square rotor plates (11) and mounted on the pair of square rotor plates (11).

The effective length of the gripping link (13) and the connecting link (14), that is, the distance between the joints (15) is the square rotor plate (1
Square rotor plate (11), equal to the side length of 1)
In the winding part, the inner side of each link (13) (14) is held in contact with the peripheral edge of the rotor plate (11). The endless link belt is driven by rotating the pair of left and right rotor plates (11) synchronously and in phase.

Both ends of each gripping link (13) protrude outward from the joint (15), and a holding member (16) such as a urethane roller stands upright on this protruding portion.

The transferred object (17), for example, a pallet, a container, a tray, or the like, is transferred to each of the holding links (13) by a pair of holding members (1).
6) Insert it between them and clamp it, and transport it with an endless link belt.

In this embodiment, in order to stably transfer the object (17) while supporting it, the guide roller row (18) is moved along the straight running portion of the endless link belt, and the guide rollers are curved along the turning portions at both ends. A conveyor (19) is attached to each.

In the illustrated embodiment, a pair of left and right square rotor plates (11) is driven to rotate around a vertical axis (12), so that the endless link belt runs.
A conveying means such as a slat conveyor may be provided instead of the illustrated guide roller row (18), and the transferred object (17) may be transferred by the conveying means. At this time, the pair of rotor plates (11) is freely rotated following the endless link belt.

In the above embodiment, the endless link belt is mounted on a square rotor plate (11) having a side length corresponding to the effective length of each of the links (13) and (14) to run. Therefore, as compared with the conventional device using a circular rotor plate, even if the effective length of the link is the same, it is possible to rotate and drive the rotor with a smaller size rotor plate.

Therefore, the interval between the parallel running portions of the link row can be shorter than that of the conventional device, the space in the center of the device becomes smaller than before, the installation area is saved, and the use efficiency of the floor space is greatly increased. Can be improved.

Second Embodiment In the above embodiment, the rotor plate is square, but the shape of the rotor plate is not limited to this and may be another polygon.

The endless link belt is formed by alternately connecting a large number of gripping links (21) and connecting links (22). However, only one connecting link (22a) and (22b) in the entire length is provided. To
Adjacent without a gripping link. This is because, when a pair of triangular rotor plates (20) are arranged in the same phase, the number of links forming the endless link belt mounted on the triangular rotor plate is odd.

To make the number of links even, one of the triangular rotor plates (20) is in phase opposition to the other, ie,
If the equilateral triangular rotor plate (20) is rotated at a position rotated by 180 ° from the position shown in the figure, the length of the linear portion between the pair of rotor plates changes, so that the link row in the linear portion periodically changes. The endless link belt becomes slack due to a large increase and decrease in tension, and smooth driving cannot be performed.

Therefore, in the second embodiment, the gripping link (21) is omitted at one place in the entire length of the endless link belt, and the linking links (22a) and (22b) are directly connected to each other, so that the link By making the number odd, smooth rotation can be achieved.

Third Embodiment FIG. 4 is a schematic plan view of a third embodiment in which a rotor plate is a rectangular rotor plate (23).

In this embodiment, the effective length of the gripping link (24) constituting the endless link belt is longer than that of the connecting link (25), and the length of the long side of the pair of rectangular rotor plates (23) is set. Is the size corresponding to the effective length of the gripping link (24), and the length of the short side is also the size corresponding to the effective length of the connecting link (25).

Also in this embodiment, a pair of rectangular rotor plates (2
By rotating 3) synchronously and in the same phase, the endless link belt can be smoothly rotated.

In FIG. 4, the effective length of the gripping link (24) is set longer than the connecting link (25), and the rectangular rotor plate (2
3) Although it is made to correspond to the length of the long side, the connecting link (25) may be made longer.

However, in order to hold the transferred object stably, it is desirable that the length of the gripping link (24) is as large as possible. Therefore, the gripping link (24) is attached to the long side of the rectangular rotor plate (23). It is preferable to adopt the configuration shown in the drawing so as to abut.

In each of the above-described embodiments, a plurality of sets of devices may be stacked one above the other as necessary to form a multi-stage transfer device. In that case, the transfer devices of each stage may be collectively driven as a simultaneous all-stage rotating device, or each stage may be independently driven independently.

Further, in the illustrated embodiment, the transferred object is nipped and transported by the gripping member provided upright on the gripping link, but a platform such as a pallet is directly mounted on the gripping link.
The present invention is also applicable to a transfer device in which an object to be transferred is placed on the gantry.
