Abstract

PURPOSE:To automatically correct meandering motion of a belt conveyer, by previously placing lateral rollers guiding a conveyer belt diagonally in an inverted V-shape clipped with the top as viewed from a forward direction of the belt further liftably setting the roller through cylinder devices. CONSTITUTION:If a conveyer belt 14 at the return side begins to deflect, a side edge of the belt 14 is contacted to one side roller 7 to press the roller 7 to the outside. If the roller 7 is pressed to the outside, pressure is applied to a master cylinder 10 by the moment, and pressurized oil in the cylinder 10 flows in a pipe 13 and is fed to a hydraulic cylinder 2 to lift a roller 4 and contact the roller to the belt 14. Here the roller 4, being mounted previously with a belt aligning angle, is lifted and contacted to the belt 14 to immediately generate aligning force, thus the belt 14 can be automatically aligned.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to an automatic centering device for a correcting hole sump.
・ Conventionally, for example, as a roller on the return side, a horizontal roller having a length corresponding to the width of the Kokuveyor belt was used. Then, side rollers are attached to the above receiver via arms attached to both ends of the stand. When the belt snakes around and pushes one of the side rollers, the horizontal roller rotates horizontally with the stand, aligning with the belt. Most of them are designed to apply force.

However, in this conventional method, the side rollers located in the meandering direction of the belt are pushed by the belt and rotated as a whole to change the position of the horizontal rollers, resulting in a lack of reliable operation. there were.

The present invention was made in order to ensure the centering action, and the left and right rollers that guide the conveyor belt are placed on roller mounts and pre-inclined in a V-shape when viewed from the direction in which the belt travels. A side roller, which is installed so that it can be raised and lowered by a telescoping device, and which is attached to the roller mount so that it can swing freely in the width direction of the belt, is located on the rear side in the direction in which the belt travels, and the swinging of the side roller is The present invention is characterized by comprising a device for operating the telescopic device.

Embodiments of the present invention will be described below with reference to the drawings.

A roller mount (3) is provided on the roller mount (1) so that it can be raised and lowered by a hydraulic cylinder (2), and the holder rotatably supports both shaft ends of the roller (4) on the pedestal (3). At the same time, the roller (4) k is tilted so as to form a . Fix the telescopic rotation stopper guide (5) to the roller mount (1). At both ends of the roller mount (1), there are brackets (6) that extend rearward in the traveling direction of the bell) Q4.
is fixed, and the shaft (8) of the side roller (7) is swingably attached to the tip of the bracket (6) with a pin (9), and the lower end of the shaft (9) is attached to the roller mount ( Connect the master cylinder (10) installed on the master cylinder (1) with the pin (6), and then connect the master cylinder (1) with the pin (6).
(2) and the lifting hydraulic cylinder (2).
When the side roller (7) is pushed outward, pressure oil is supplied from the master cylinder QO to the hydraulic pressure cylinder (2) so that the roller (4) is raised.

With the above configuration, in the normal state where the conveyor belt α→ is not meandering, the roller (4) is lowered by its own weight, and the pressure oil in the hydraulic cylinder (2) is returned to the master 7 cylinder QO. the side rollers (
7) is in an upright position.

Now, for example, when the conveyor belt (b) on the return side starts to shift, the side edge of the belt α comes into contact with one of the side rollers (7), and the side roller (7) continues to act in the direction of pushing it outward. do. When this side roller (7) is pushed outward, the moment causes the master 7 cylinder αQ
pressure is applied to As a result, the pressure oil in the sear turn cylinder QO is supplied into the hydraulic cylinder (2) through the piping hole, and the hydraulic cylinder (2) is operated to extend, and the roller (4) is
Raise the belt and bring it into contact with the belt 11 α◆. At this time, since the roller (4) is installed with a belt alignment angle in advance, it rises and comes into contact with the belt α→, thereby immediately generating an alignment force and automatically aligning the belt α4. It can be aligned to While the side roller (7) is being pushed by the belt α→, the roller (4) is floated.

When the belt α◆ is aligned and the side roller (7) is no longer pushed, the moment no longer acts on the master cylinder, so the roller (4) begins to descend due to its own weight, causing the pressure oil in the hydraulic cylinder (2) to drop. returns into the master cylinder (a), and the side rollers (7) are automatically returned to the upright position.

Incidentally, although the case of the return roller has been described above, it goes without saying that the present invention can be similarly applied to the carrier roller.

As described above, according to the automatic alignment device of the present invention, when the side rollers are pushed by the meandering of the belt, the rollers are raised and aligned, so that the rollers are immediately adjusted by the meandering of the belt. The belt operates reliably in the desired centering position, and even when the load of the belt is applied to the rollers, the belt can be reliably self-aligned, which is an excellent effect.
