Abstract

PROBLEM TO BE SOLVED: To enable conveying speed high even in a conveying article having a low strength by providing a flat plate member that has been provided so as to be retractable through the gap between the rollers that have been arranged in parallel, so that the surface pressure at the time of collision of the conveying article can be reduced. SOLUTION: Suppose that a conveying article 6 is conveyed from right to left, first, the piston rod 32 and the fixed plate 33 of an elevator 3 are moved upwards, and accordingly the flat plate member 2 is also raised, so that at least a part thereof is projected upwards through between the rollers 51. When the conveying article 6 is still conveyed, it is soon abutted on the abutting surface 22 of the flat plate member 2. In that case, the flat plate member 2 is slightly turned making a base end part 21 a center, and pushes in the operating rod 42 of a shock absorber 4. As a result, the shock absorber 4 absorbs the kinetic energy of the conveying article 6. Thus, even if the strength of the conveying article 6 itself is low, the damage given to the conveying article 6 can be reduced as compared with the conventional one.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is designed to carry out a predetermined operation on an object conveyed on a roller conveyor.
The present invention relates to a conveyer stopper for a roller conveyor used to temporarily stop at an appropriate position.

[0002]

2. Description of the Related Art Conventionally, various kinds of stoppers of this kind have been known, but a portion which comes into contact with a conveyed product is usually constituted by a roller or a shaft.

[0003]

When the strength of the conveyed product itself is high, such as in a pallet, there is no problem even if the rollers and shafts come into contact with each other, but the conveyed product itself is as strong as a cardboard box. When the value is low, the roller or shaft may come into contact with the roller or shaft to cause local dents or damage such as crushing. In particular, in recent years, improvements in roller conveyors have made it possible to increase the transfer speed to a considerably high level, but if the transferred product is of such low strength, it should not be damaged. Driving at low speed is still underway.

The present invention has been made in order to solve the above-mentioned problems, and it is a roller that reduces the surface pressure at the time of collision of a conveyed object and makes it possible to increase the conveying speed even for a conveyed object having low strength. An object of the present invention is to provide a conveyer stopper for a conveyor.

[0005]

In order to achieve the above object, the conveyer stopper for roller conveyors of the present invention performs the operation by stopping the conveyed goods conveyed on the roller conveyor at a predetermined position. After the end, in order to restart the conveyance of the conveyed article, the conveyed article stopper for the roller conveyor for releasing the stop has a flat plate member that can be retracted through the gap between the rollers arranged in parallel. It is characterized by

In this case, the flat plate member is rotatably connected to an elevator arranged below the roller conveyor about a base end portion thereof, and a shock absorber arranged in the elevator is operated. It is preferable that the back surface of the flat plate member is provided so as to be able to contact the tip of the rod.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail based on embodiments shown in the drawings. In the figure, 1
Is a conveyer stopper for a roller conveyor according to the present embodiment, and includes a flat plate member 2, an elevator 3, and a shock absorber 4.

The flat plate member 2 has a width shorter than the length between the support members (not shown) on both sides supporting the rollers 51 arranged in parallel on the roller conveyor 5, and the adjacent roller 51 Any shape may be used as long as it has a thickness thinner than the space between them,
In order to reduce the surface pressure at the time of collision with the transported object as much as possible, it is preferable that the area is as large as possible. The flat plate member 2 may be made of wood, plastic, or the like, and a rubber material (not shown) may be provided on the contact surface 22 with the conveyed object in order to further reduce the impact at the time of collision. ) Or the like may be attached.

The elevator 3 is arranged below the roller conveyor 5, is fixed to a cylinder 31, a piston rod 32 that moves up and down with respect to the cylinder 31, and an upper end of the piston rod 32, and moves the piston rod 32 up and down. It is configured to have a fixing plate 33 that moves up and down accordingly. And the fixing plate 3
The flat plate member 2 described above is connected to the connecting plate 34 connected to
The base end portion 21 is connected and fixed via a shaft 34a, and the flat plate member 2 is provided so as to be rotatable about the shaft 34a (base end portion 21) at a predetermined angle along the transport direction. The elevator 3 may be of any type as long as it has such a function, and an air-operated type, a hydraulic type or the like can be used.

The shock absorber 4 has a cylinder portion 41.
Is fixed to the upper surface of the fixed plate 33 of the elevator 3, and the fixed plate 3
It is provided so as to move up and down by the vertical movement of 3. Further, the shock absorber 4 is arranged such that the tip end 42 a of the operating rod 42 can come into contact with the back surface (the back surface of the contact surface 22 with the conveyed object) 23 of the flat plate member 2. The type of shock absorber 4 is not particularly limited, and various conventionally known shock absorbers can be adopted. If the transported object is heavy or the transportation speed is higher and the kinetic energy of the transported object is larger, a plurality of shock absorbers 4 can be provided.

Next, the operation of the embodiment will be described. Assuming that the conveyed product 6 flows from the right to the left in FIG. 1, first, the piston rod 32 and the fixing plate 33 of the elevator 3 move upward, and along with this, the flat plate member 2 also moves upward, At least a part of the rollers protrudes upward from between the rollers 51. When the transported object 6 is transported as it is, the flat plate member 2
Abutting surface 22 of. At that time, the flat plate member 2 slightly rotates around the base end portion 21 and pushes the operating rod 42 of the shock absorber 4. As a result, the shock absorber 4 absorbs the kinetic energy of the conveyed object. In this way, when the conveyed product 6 is stopped, a predetermined work is performed on the conveyed product 6, such as placing or packing articles.

After the work is completed, the piston rod 32 of the elevator 3 descends, and the flat plate member 2 also moves along with the roller conveyor 5 accordingly.
As it is sunk below, the conveyed product 6 moves again on the roller conveyor 5 and is used for the next work process. When the next conveyed object approaches, the piston rod 32 of the elevator 3 moves up again, and the above operation is repeated.

[0013]

The roller conveyor conveyor stopper according to the present invention employs a flat plate member as a member that comes into contact with the conveyor, so that the surface pressure at the time of collision can be reduced and the strength of the conveyor itself can be reduced. Even if it is low, it is possible to reduce damage to the conveyed product as compared with the conventional one. For this reason,
It is also possible to increase the transport speed as compared with the conventional one. Furthermore, when a shock absorber is used, such an effect can be exhibited more remarkably.
