Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corner transer (transfer direction changing device) for changing the transfer direction of an object to be conveyed in a roller conveyor or a chain conveyor device.

[0002]

2. Description of the Related Art Conventionally, when changing the transfer direction of an object to be conveyed in a roller conveyor device, a conveyor belt or a chain conveyor flowing at a right angle to the conveying line is moved up and down, or pushed and pulled by a pusher to another line. I was transferring.

[0003]

However, in the conventional method, the apparatus is complicated, and the control at the conversion position is complicated, which is inevitably expensive.

An object of the present invention is to obtain a corner transer which can omit the above-mentioned vertical mechanism and control mechanism of the belt conveyor and the chain conveyor.

[0005]

In order to solve the above-mentioned problems, the corner transer according to the present invention has the following structure. An endless chain is stretched between the adjacent rollers of the roller conveyor at the transfer direction conversion position so as to be movable in the axial direction of the roller below the surface of the adjacent rollers, and laterally of the endless chain. In addition, due to the movement of the endless chain, the rollers protruding from the surface of the adjacent rollers are protruded from the surface of the roller conveyor over the entire length of the roller shaft, and only the chain not provided with the rollers has the roller shaft. A corner transer which is provided in a partial range of the endless chain so as to be in a certain state over the entire length.

[0006]

1 is a plan view of a corner transer having a basic structure according to the present invention, and FIG. 2 is an enlarged plan view showing the structure of a corner transer portion of FIG. Further, FIG. 3 also shows a state in which the conveyed product is transferred to the corner transer portion, and (a) is XX of FIG.
A sectional view along the line, (b) a sectional view along the line YY,
4 (a) and 4 (b) are views similar to FIG. 3, showing a state in which a conveyed product is laterally converted and transferred.

As shown in FIG. 1, a conveyed product 1 is transported in the direction of an arrow on a conveyor roller 2 of a roller conveyor A composed of a plurality of conveyor rollers 2, and the direction of the roller conveyor C or D is changed at a corner transer B portion. It is configured to be transferred after being changed in direction. The conveyor roller 2 is driven by an appropriate means in the conveying direction of the conveyed object, and a guide side plate 3 is provided on the side of the conveyor to prevent the conveyed object 1 from falling off the conveyor.

To further explain, Corner Transer B
Between adjacent conveyor rollers 2a and 2b of FIG.
~ As shown in Fig. 3, the endless chain 4 is stretched in the length direction of the conveyor roller, and the corner transer B
Drive motor 6 with chain sprocket 5 at the bottom
Similarly, a drive sprocket 7 that also drives the other endless chain 4 provided on the other side is attached to the machine frame 8, and the chain 4 extends along the conveyor roller 2 between the guide sprockets 9 and 9 on both sides. The chain 4 is driven and driven by the drive motor 6 to move the chain 4 between the adjacent rollers in the axial direction. In addition, the guide sprocket 9,
The machine frame 8 is provided with a chain rail 10 that supports and guides the lower side of the chain 4 stretched around 9 so that the chain 4 can move in parallel with the conveyor roller shaft.

In the chain 4, for example, as shown in a plan view (a), a front view (b) and a side view (c) of FIG. 5, rollers 11 are alternately provided on one side of a chain shaft 4a. As shown in FIG. 4 (b), the size of 11 is such that when the chain 4 to which the roller 11 is attached is located between the conveyor rollers 2 a and 2 b.
The height is higher than the plane formed by a and 2b. The rollers 11, 11, ... Are attached so as to occupy approximately half the length of the endless chain 4. That is, as shown in FIG. 3B, when the conveyed article 1 is transferred from the right side of the figure on the conveyor roller, the chain 4 without the roller 11 is attached so as not to obstruct the conveyance by the conveyor roller 2. Is below the plane formed by the conveyor roller 2, and when the conveyed article 1 is transferred in the axial direction of the conveyor roller 2 as shown in FIG. 4 (a), as shown in FIG. 4 (b), Two
The rollers 11, 11, ... Are positioned above the plane formed by the, and the article 1 is attached to the chain 4 by the rollers 11, 11 ,.
It is configured to move up. However, if the chain 4 is driven with the conveyed object 1 placed on the rollers 11, the conveyed object 1 is transferred.

The drive control of the chain 4 can be easily performed by providing a conveyed object detector at an appropriate position of the corner transer B and detecting that the conveyed object has come onto the corner transer B. .

A roller 11 attached to a part of the chain 4.
As a mounting configuration of the above, it may be mounted as shown in FIG. 6, which is a view similar to FIG. Further, even if the chain 4 is provided with a roller having the movement direction of the chain as a support shaft, the conveyed object placed on the roller can be moved by the movement of the chain 4. Even if the chain is appropriately provided with protrusions instead of rollers, it is possible to transfer the conveyed objects by moving the chain.

[0012]

According to the present invention, at the direction change position, the conveyed object conveyed by the conveyor is provided with a roller having a size protruding from the plane formed by the adjacent conveyor rollers between the adjacent conveyor rollers. By providing a part of the chain that moves in the roller axis direction, the direction of the transported object can be changed and transferred easily by the action of the roller protruding from the roller conveyor plane in the transfer direction conversion part of the transferred object. It can be done reliably.

Further, the roller mounting portion of the roller-equipped chain is not located in the plane position formed by the roller chain so that the roller is inoperative with respect to the conveyed object, so that a corner provided on the roller conveyor is provided. It is also possible to use the transactor so that the conveyed product goes straight without changing the direction to the right or left.

The conveyor transfer speed and the endless chain transfer speed in the corner transers are appropriately adjusted and used as needed.
Further, by switching the driving direction of the endless chain, it is possible to easily change the conveyed object from the traveling direction to the left and right directions.
