Abstract

PURPOSE:To enable pallets of various widths to be carried by bringing a pair of parallel conveyor frames for supporting a endlesslike carrier body close to or keeping them apart from each other in the direction perpendicular to the carrying direction. CONSTITUTION:Air cylinders 63, 65, 67 and 69 which are arranged on the front or rear side of conveyor frames 3A, 3B are operated to move piston rods 71, 73, 75 and 77 forward or backward. Thereby the conveyor frames 3A, 3B are moved in a direction approaching each other or separating from each other. Thus, by moving the conveyor frames 3A, 3B so as to suit the width of pallets to be carried, pallets of various widths can be coped with.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a conveyor in which a pair of conveyor frames can be moved toward and away from each other in a direction orthogonal to the conveyance direction.

(Prior Art) Conventionally, a conveyor is provided with, for example, a chain supported by a pair of conveyor frames extending in the conveyance direction, which are interlocked and connected, and the pair of conveyor frames are fixed in a direction perpendicular to the conveyance direction. The transport track width is fixed to, for example, a frame. Therefore, the width of the conveyance track has been determined by the size of the pallet, grounding conditions, etc.

(Problems to be Solved by the Invention) By the way, since the pair of transport tracks in the above-mentioned transport conveyor are fixed, when the pallet 113 is changed in various ways, the pallet placed on the transport conveyor becomes unstable. This may result in a dangerous conveyance situation, and the plate materials placed on the pallet may fall from the pallet.

Further, since the conventional conveyor has a fixed pair of conveyor frames, it can only be used for planar movement, and there is a problem in that it is not possible to transfer pallets in the vertical direction.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a conveyor that can accommodate various changes in pallet width and that can transfer pallets in the vertical direction.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention provides an endless conveyance belt supported by a pair of conveyor frames extending in the conveyance direction, which are interlocked and connected. The transport conveyor is constructed by providing a movement drive device that allows the pair of conveyor frames to move toward and away from each other in directions orthogonal to the transport direction.

(Function) By employing the conveyor of the present invention, pallets placed on a pair of conveyor frames extending in the conveyance direction are conveyed in the conveyance direction by an endless conveyance belt. Therefore, for example, the plate materials stacked on the pallet are transported in the transport direction.

The moving drive device allows the pair of conveyor frames to move toward and away from each other in directions perpendicular to the conveyance direction, so even if the width of the pallet is changed, the pallet can be conveyed in a stable state, and the pallet can be moved in the vertical direction. It can also be delivered to.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

Referring to FIG. 1, the conveyor 1 includes a pair of conveyor frames 3A and 3B, and a pair of conveyor frames 3A and 3B.
It consists of a drive device 5 that drives an endless conveyance belt supported by A and 3B. In FIG. 1, it is assumed that the object is conveyed from the right to the left as indicated by the arrow, and the left side is the front in the conveyance direction, and the right side is the rear in the conveyance direction.

The conveyor frame 3A extends in the conveying direction, and rotatable sprockets 7.9 are provided at the front and rear parts of the conveyor frame 3A, respectively. A chain 11 as an endless conveyor belt is wound around the sprockets 7 and 9. Moreover, conveyor frame 3A
Front part in.

A linear guide 13.15 extending in a direction perpendicular to the transport direction is arranged at the lower part of the rear part.

On the other hand, the conveyor frame 3B also extends in the conveyance direction, and similarly to the conveyor frame 3A, rotatable sprockets 17 and 19 are provided at the front and rear parts of the conveyor frame 3B, respectively. That sprocket 17
A chain 21 as an endless conveyor belt is wound around and 19. Moreover, it is the front part of the conveyor frame 3B.

A linear guide 23, 25 extending in a direction perpendicular to the conveying direction is arranged at the lower part of the rear part.

The conveyor frames 3A, 3B, the linear guide 23.
25 is attached to frames FA and FB.

Spline shafts 27.degree. 29 are attached to the axes of the sprockets 9 and 19, as shown in FIG. A fitted shaft 31.33 is mounted on the splined shaft 27.29. The conveyor frames 3A, 3 are attached to the spline shafts 27 and 29.
B is integrated through a collar 35°37.

Sprockets 3 and 9 are attached to the lower part of the shaft 31 in FIG. 1, and a chino 43 is wound around the sprocket 39 and the sprocket 41.

A shaft 45 extending vertically in FIG. 1 is attached to the sprocket 41. As shown in FIG.

A sprocket 47 is fitted onto the upper part of the shaft 45, and a chino 51 is wound around the sprocket 47 and the sprocket 49.

A drive shaft 53 is attached to the sprocket 49, and a drive motor 55 is attached to the drive shaft 53.

A sprocket 57 is fitted to the lower part of the shaft 45 in FIG. 1, and a chino 61 is wound around the sprocket 57 and the sprocket 59 fitted to the shaft 33.

With the above configuration, when the drive motor 55 is driven, the sprocket 49 is rotated via the drive shaft 53. The rotation of sprocket 49 is Cheno 51, sprocket 47
is transmitted to the shaft 45 via. The rotation transmitted to the shaft 45 is transmitted to the sprocket 41. It is transmitted to the shaft 31 via the chino 43 and the sprocket 39, and also to the sprocket 57. It is transmitted to the shaft 33 via the chino 61 and sprocket 59.

The rotation transmitted to the shaft 31.33 is further transmitted to the sprockets 9, 19 via the splined shaft 27.29. The rotation of the sprockets 9, 19 is wound around the sprockets 9, 7: 19, 17 and is transmitted to the chain 11.21, and the transport table (not shown) attached to the chain 11.21 is moved in the transport direction. Become. For example, a pallet in which a plurality of plate materials are stacked is placed on the transport table and is moved in the transport direction.

For example, an air cylinder 6 is installed as a moving drive device on the front side and the rear side of the conveyor frames 3A and 3B.
3,65:67.69 are arranged, and the piston rods 71,73 near 5,77 provided at the tips of the air cylinders 63,65:67.69 are attached to the conveyor frames 3A, 3B. There is. In addition, air cylinders 63°65:67.69 are for frames FA and F, respectively.
It is attached to B.

With the above configuration, air cylinder 63, 65: 67.69

In FIG. 3, for example, the conveyor frame 3A is moved to the right and the conveyor frame 3B is moved to the left, that is, the conveyor frames 3Δ and 3B are moved away from each other while being guided by linear guides 13.15:23 and 25. can be done. Also, air cylinder 63.65;
7.69 is actuated to push the piston rods 71, 73 nearer 5, 77, and in FIG. 3, for example, the conveyor frame 3A is moved to the left and the conveyor frame 3B is moved to the right.

Linear guide 13°15 in the direction of moving 3B closer to each other:
23.25 can be guided and moved.

In this way, since the conveyor frames 3A and 3B can be adjusted to move toward and away from each other in the direction perpendicular to the conveyance direction, that is, in the track width direction, it is possible to adjust the pallet width to various arbitrary changes, and the pallet can be transported in a stable state. Can be transported. In addition, since the track width can be adjusted by changing it arbitrarily, for example, as shown in Fig. 4, conveyor frames 3A and 3
If a double lifter 79 is provided in B, the pallet P can be transferred downward.
