Abstract

PURPOSE:To provide a difference in horizontal direction between the carry-in and carry-out positions for objects to be transported, by coupling together No.1 and No.2 frames supporting a drive roller and a follower roller with possibility of bending in the horizontal direction, and by absorbing elongation and contraction of the belt with an expansive absorption roller. CONSTITUTION:Pins 6C1, 6C2 are set in a beam 11 at the upper front and rear walls 9, 9 of supporting frame 7 and a beam 12 at the bottom of both side walls 8, 8 and said supporting frame 7 is borne by a coupling mechanism in such a way as rotatable horizontally. The tension side outside surface of a belt 5 led in from guide parts 9A, 9B of the supporting frame 7 recessedly is wound on an expansive absorption roller 13A, while the loose side outside surface of the same belt 5 led in from guide parts 10A, 10B recessedly is wound on another roller 13B, If the follower roller side is pressed, a frame 4 bends with respect to a frame 3 with the pins 6C1, 6C2 as fulcrum. Accordingly, elongation and contraction of the belt 5 at its ends in width direction is absorbed through rotation of the rollers 13A, 13B round vertical axis through mechanisms 18A, 18B.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a pet conveyor device that can provide a horizontal difference between the loading and unloading positions of objects to be conveyed, for example.

(Prior art) For example, when conveying objects from process A to process B shown in FIG. When transporting objects that are alternately brought into the loading ports al and al are collected at process B and carried out, or when process B is the loading side and the transported objects are transported from process B to process A by t-rail, When distributing and carrying out from one inlet in process B to two outlets Ikl, a in process A, at least three conveyor fins 20.21.2
2 will be required.

Like this, three belt conveyor lines 20°21.2
Even if 2 is set to 9, the first conveyor fin 20 and the second conveyor fin 20
．． Since a step is formed at the merging point with the third conveyor fin 2.1.22, from the first conveyor fin 20 to the second conveyor fin 2.
．． When transferring to the third conveyor twin 21.22 or when transferring to the second conveyor twin. When transferring from the third conveyor line 21, 22 to the first conveyor fin 20, the conveyed object must be dropped by the difference in level.

Therefore, it cannot be applied to objects to be transported that must avoid impact.

On the other hand, from the first conveyor fin 20 to the second conveyor fin 20. When conveying toward the third conveyor fin 21.22, tJIJ
At the branching point between the conveyor fins 20 of l and the conveyor fins 21 and 22 of gz and g3, there is a distribution system that distributes the conveyed objects on the first conveyor fin 20 to the second conveyor fin 21 or the third conveyor fin 22. However, the device must be installed separately, which poses a problem of complicating the structure.

(Purpose of the Invention) This invention was made to solve the above-mentioned conventional problems, and it is possible to transport objects on the same plane by one conveyor device, and also to make it possible to transport objects on the same plane, and to have relative positions between the loading position and the unloading position. It is an object of the present invention to provide a belt conveyor device which can provide a horizontal difference and which does not require a device for shaking out objects to be conveyed.

(Structure of the Invention) In order to achieve the above object, a belt conveyor device according to the present invention is a belt conveyor device in which an endless belt is stretched between a driving roller and a driven roller, and the driving roller is rotatably supported. It has at least one set of connection mechanisms that connect the first frame and the second frame rotatably supporting the driven roller so as to be bendable in the horizontal direction.

A support frame is provided which is rotatably supported in the horizontal direction by the coupling mechanism and is provided with guide portions for inwardly recessing the outer surfaces of the belt on the tension side and the slack side of the endrespel.

The support frame also includes a telescopic absorbing roller around which the outer surface of the bag recessed from the guide portion is wound, and a telescopic absorbing mechanism configured such that the telescopic absorbing roller is rotatable around the vertical axis of the belt conveyor device. The structure has the following.

Therefore, 11 frames and wrJz centering around the connection mechanism.
By relatively bending the frame in the horizontal direction, the elongated side and the contracted side of the endless belt are absorbed by the elastic absorption roller that rotates around the vertical axis of the belt conveyor device by the elastic absorption mechanism. A horizontal difference can be provided between the carry-in position and the carry-out position.

That is, by sequentially displacing the second frame 4 to the positions of virtual #iX, solid line, and virtual line y, the respective loading ports &1. The objects to be conveyed sequentially from &・, a,
It is possible to collect them in the frame 3 and carry them out to the carrying out port of process B.

Of course, by reversing the positions of the driving roller 1 and the driven roller 2 to make it the process Bt-carrying side and making the process A the unloading side,
The objects to be conveyed carried in from the process B side can be distributed by the second frame 4 and carried out from the carry-out ports &, , a@, and afi.

Note that in the above embodiment, only one set of connection mechanisms 6 is used to connect the first. Although an example in which the second frames 3 and 4 are directly connected has been described, the present invention is not limited to the above-mentioned embodiment. can be formed in a meandering shape within the same horizontal plane.
