CONSTITUTION:Roller conveyors 4A, 4B with an air jack are disposed in the intersecting part 3 of carrier paths 1A, 1B consisting of a group of roller conveyors 2A, 2B so that the disposition direction of the roller conveyors 4A, 4B is identical with that of the roller conveyors 2A, 2B. Loading and unloading objects onto and from the roller conveyors 4A, 4B allows changing the direction of the objects which have been carried up to the intersecting part 3 via the said carrier paths 1A, 1B.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a direction change size of an object to be conveyed on a roller conveyor and its apparatus.

[0002]

2. Description of the Related Art Conventionally, in a load carrying device using a roller conveyor, when changing the carrying direction of a carried object, FIG.
As shown in Fig. 7, a plurality of rows of roller conveyors a and b are laid so as to be orthogonal to each other, or as shown in Fig. 7, a roller conveyor d is attached to a support board C which is connected to a conveyance path and bends in a required direction. In case of arranging in a row, or laying so that a direction changing portion supporting a large number of spheres f on a frame e as shown in FIG. I'm using a turntable.

[0003]

In the direction changing device shown in FIG. 6, the roller conveyors are arranged so as to be orthogonal to each other, but since the surfaces of the rotating roller conveyors are at the same height, it is possible to convey the object. Friction occurs when changing the direction of an object, which is not suitable for transferring large loads. Further, in the direction changing device shown in FIG. 7, the direction of changing the direction of the conveyed object is limited, there is no freedom of direction change, and the installation place is wide.

In the direction changing device shown in FIG. 8, the direction of the transported object is changed by a large number of spheres, but when changing the direction of a large load, the device becomes large and uneconomical. In addition, the turntable requires a large amount of equipment for direction change. The present invention has been proposed in view of the above problems of the prior art, and an object of the present invention is to automatically control the direction change of a transported object in a transportation facility with a simple configuration and transfer the transported object. Another object of the present invention is to provide a method and apparatus for changing the direction in a roller conveyor that can smoothly perform sorting.

[0005]

In order to achieve the above-mentioned object, according to the direction changing method in the roller conveyor according to the present invention, a plurality of roller conveyors are respectively provided in rows at the intersections of the mutually intersecting conveying paths. , Arranging a roller conveyor with an air jack in a direction coinciding with an arrangement direction of the roller conveyor of each of the transport paths, and attaching the object to be transported carried into the intersection through the roller conveyor of the transport path with the air jack. By moving the roller conveyor up and down, the direction of the roller conveyor is changed, and the roller conveyor is transferred to the other conveying path that intersects with the conveying path.

In order to smoothly carry out the above method,
The direction changing device in the roller conveyor according to the present invention,
Roller conveyors with air jacks are arranged at the intersections of the transport passages in which a large number of roller conveyors are arranged in a row and in a direction corresponding to the arrangement direction of the roller conveyors of the respective transport passages. The conveyor is provided between the roller conveyor bearing member and the bottom of the conveying path.
It is configured by interposing an air tube connected to an air supply / exhaust source.

[0007]

According to the present invention, as described above, the roller conveyors with air jacks are arranged in a row at the intersection of the conveying paths in which a large number of roller conveyors are respectively arranged in a direction corresponding to the arrangement direction of the respective roller conveyors. Then, by controlling the raising and lowering of the roller conveyor by the air jack, the transported object is transferred from the conveyor of one transportation path to the conveyor of the other transportation path at the intersection, and the direction of the transported object is changed. It is a thing.

[0008]

The present invention will be described below with reference to the illustrated embodiments. 1A and 1B are a large number of roller conveyors 2A and 2B, respectively
Are conveyance paths that are arranged in a row and intersect at the intersection 3 at right angles.
The intersection 3 is provided with a step on the floor,
Roller conveyors 4A and 4B with air jacks are arranged on the same straight line as the roller conveyors 2A and 2B of A and 1B.

FIGS. 4 and 5 show the details of the roller conveyors 4A and 4B with air jacks, and the conveying path 1
A flat elastic air tube 8 is installed between a fixed grooved steel 5 installed on the floor so as to communicate with A and 1B and a grooved steel bearing member 7 on which a roller 6 is mounted. An air pipe 9 attached to the tube 8 is connected to a compressor and an opening / closing valve as well as an operation panel (not shown) for controlling these.

Since the illustrated embodiment is constructed as described above, the objects to be conveyed are, for example, from the conveyance path 1A to the conveyance path 1B.
In the case of transferring to the transfer path 1A, the air is preliminarily injected into the air tube 8 of the roller conveyor 4A with an air jack in the crossing portion 3 to expand the air tube 8 as shown in FIG. After holding the same level as that of the roller conveyor 2A, and thus moving the conveyed object from the conveying path 1A to the crossing portion 3, the roller conveyor with an air jack 4B is lifted to support the conveyed object in the same manner as described above. By contracting the air tube 8 of the attached roller conveyor 4A and lowering the roller 4A, the roller conveyor 4B and the roller conveyor 2B of the conveying path 1B are at the same level, and the object to be conveyed is in the direction of the conveying path 1B. Be transferred.

An interlocking mechanism such as an endless chain is connected between the rotary shaft of the roller 6 and the drive motor, and the motor-equipped roller conveyor 4 with the air jack is connected by the motor.
By raising and lowering A and 4B, it becomes possible to change the direction of the transferred object, and it becomes possible to automatically transfer the transferred object by computer control.

[0012]

As described above, according to the present invention, the transfer direction of the object to be transferred can be changed by moving up and down the roller conveyor with the air jack provided at the intersection of the transfer path by the roller conveyors that intersect with each other. It is possible to easily carry out, the transportation equipment can be easily automated, the equipment can be simplified, and the automatic transfer direction control can smoothly transfer and sort the transported objects.
