Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a transport roll that transports objects such as veneers.

(Background technology) Conveyors that convey adhesive-coated veneers generally include: (a) flat belt conveyor (b) roll conveyor (c) V-belt, round belt conveyor, etc. When using these, glue adheres and accumulates on the conveyor due to long-term use, and
The problem is that it takes time to clean them.

In addition, especially when conveying double-sided coated veneers using conventional conveyors, adhesive adhesion and accumulation are significant, and the adhesive surface of the veneer becomes rough, which poses quality problems.
Almost unusable.

In addition, a so-called live roller conveyor, as shown in Fig. 1, is partially used as a conveyor for conveying double-sided coated veneers, but it is constructed by arranging a large number of plastic disks close to each other.
Since there are many parts that come into contact with the veneer, there is a lot of glue adhesion and accumulation, and cleaning of the glue that has adhered and accumulated on the outer periphery of the disk and between each disk requires cleaning the disks in large numbers close to each other. The problem is that it is very difficult to do so.

(Purpose of the invention) The present invention was proposed in view of the above points, and its purpose is to use the conveyor roll, which is a component of the conveyor, when conveying adhesive-coated veneers. It also reduces the adhesion, adhesion, and accumulation of glue to surfaces, reduces roughening of the coated surface of adhesive-coated veneers, and facilitates cleaning of adhesion and accumulated glue. It is an object of the present invention to provide a transport roll that can be lightweight, reduce costs, and can be used not only for transporting adhesive-coated veneers but also for general transport.

(Disclosure of invention) The present invention will be explained below with reference to the drawings.

FIG. 2 shows an embodiment of the conveying roll according to the present invention, and in the figure, 1 is a drive shaft;
A plurality of discs 2 are provided at desired intervals, each disc 2 is covered with a shrink tube 4, and a transport roll 3 is constructed. After being coated, the shrink tube 4 is thermally shrunk by applying heat, and the surface between each disc 2 is shrunk toward the drive shaft 1 side. In this case, even though the disc pitch between the discs 2 is wider than that of the conventional live roller shown in FIG. 1, the space between each disc 2 is covered by the shrink tube 4. Because of this, veneer 8
(See Figure 3) When transporting objects, the veneer 8
Even if the width is small, the veneer 8 can be prevented from falling onto the drive shaft 1 side, so there is no problem in conveying the conveyed object. As a result, the number of discs 2 can be reduced, making the transport roll 3 lightweight and inexpensive. FIG. 3 shows a case where transport rolls 3 arranged at intervals are driven. That is, a bearing 5 is provided at the outer end of the drive shaft 1, and a timing pulley 6 is provided at the end of the drive shaft 1 at a position outside the bearing 5. (not shown), the timing pulley 6 rotates via the timing belt 7, and the conveyor roll 3 supported via bearings 5 in a well-known manner rotates. ing. Therefore, a large number of conveyor rolls 3 are arranged in parallel at appropriate intervals, and the veneer 8 is conveyed by the conveyor rolls 3 of this conveyor in the direction shown by the arrow.

However, by having such a configuration,
The transport roll 3 can be easily attached to and removed from the timing pulley 6, and if glue adheres or accumulates on the shrink tube 4, the transport roll 3 can be replaced with another transport roll prepared in advance. It is possible to exchange it instantly. In addition, if the conveyor roll 3 has been replaced and cannot be reused even after cleaning as described below, remove the shrink tube 4, cover it with a new tube, and prepare it for the next replacement. Good.

Note that since the glue adheres and accumulates on the surface of the shrink tube 4, dirt can be removed by wiping the surface, making cleaning easy.

(Effects of the invention) As described above, according to the invention, there is a drive shaft 1, a plurality of discs 2 attached to the drive shaft 1 at desired intervals, and a system that covers each of these discs 2. , and the surface between each disk 2 is provided with a contraction tube 4 that contracts toward the drive shaft, (a) the pitch between the disks is relatively large, and the contraction tube between the disks contracts toward the drive shaft. Because I am
Adhesion and accumulation of glue on the conveyor rolls constituting the conveyor can be reduced.

(b) Since the pitch between the discs is relatively large and the veneer has a small portion that comes into contact with the conveyance roll, roughness on the coated surface of the adhesive-coated veneer can be reduced.

(c) Glue adheres and accumulates on the shrink tube, so
Cleaning is easy as it is only necessary to clean the surface of the shrink tube.

(d) Since the number of discs can be reduced, the transport roll can be made lighter and less expensive.

(e) It can be used not only for transporting adhesive-coated veneers, but also for general transport.

There are other effects.
