CS211589B1 - A synchronous chain conveyor, especially for loads stored outside the center of gravity of the carrier - Google Patents

Abstract

The invention relates to the inter-operational transport of components or assemblies, especially in mechanical engineering. The invention solves the problem of transporting components that are stored on conveyor carriers outside the load. The essence of the invention lies in the fact that, opposite the driving sprockets, support sprockets are stored on the other side of the carriers under the guide pulleys. A support bar is firmly stored between the end support sprocket and the driving sprocket stored behind it under the groove of the guide pulleys of the carriers.

Description

1 211589

The present invention relates to a synchronous chain conveyor, especially for transporting off-centered conveyor belts.

So far known synchronously chain conveyors are converted so that. the carriers are attached to the diagonal diagonals by means of support pins on the chain guide shells, opposite to the support carriers on the other side provided with guide rollers. Under the guide bushes and below the guide pulleys, upper and lower guide rails are provided. The chain / wheels in the end positions are offset relative to each other in the direction of the bearing pins by their mutual spacing. This arrangement allows the carriers to be transported across the conveyor in a horizontal position. The disadvantage of this is that if the load to be carried is not supported on the carrier in the center of gravity, then the carrier pins of the carriers can be damaged and the carrier chains can be damaged in the end positions. ,

The above-mentioned drawbacks are eliminated by a synchronous chain conveyor, especially pre-installed outside the center of gravity of the carriage according to the invention, whose supporting chains are rotatably mounted opposite the drive chain wheels on the other side of the carriers under the guide rollers. The support rail is fixedly supported by the end support sprocket and the follow-up entrainment wheel attached thereto.

The synchronous chain conveyor achieves a stable position of the carriers in the end positions of the conveyor even when the load to be carried is stored on the carrier outside the center of gravity. The invention extends the use of the conveyor and increases its lifetime.

In the accompanying drawing, an exemplary embodiment of a synchronous chain conveyor is shown where the conveyor portion is drawn in space. ,

The synchronous chain conveyor consists of a lava chain 2 wrapped on the left-hand carrier wheels 2 and a right-hand chain 3-wrapped on the right carrier chain wheels2. On the chains 2, 2 in the guide sleeves 4 a carrier 4 is attached by means of support pins 2 which are placed in the diagonal on the carriers. . In contrast to the support pins 7 on the second side of the carriage 4, guide rollers 6 are provided.

The upper guide rails 11 and lower guide rails 12 are arranged under the guide rollers 2 and the guide chains 11 of the chain 2, the thrust drive chain wheels 2 being spaced apart from each other in the direction of the support pins 20 by the spoke wheels. In contrast to the carrier chain wheels 2, the supporting chain wheels 25 are pivoted from the other side of the carriers below the guide pulleys 9. A support strip is fixed between the end support chain wheel 16a and the driving chain wheel mounted behind it under the guide roller track 9. 4. The drive chain wheels 5, 5 and the support chain wheels 15, 16 are rotatably mounted by pins 10 in brackets 25. The brackets 13 are mounted on stems, on the frame structure and the like (not shown in the figure). The drive unit (not shown in the figure) drives one pair of driving chain wheels 2 * 2 'carrying the left and right chains 2' 5 'and the chain 2, 2 carrying the carrier 4, whereby the loads can also be transported outside its center of gravity . Transported loads can be spare parts, eventually assembled various units, or carried out other technological operations. In the end positions, the carriers 2 are supported by the support pins 7 in the same position as on the straight sections of the conveyor. x · ·.

On the straight sections of the conveyor, the guide rollers 2 and the guide sleeves 2 of the chains 2 ' 3 are rolled over the upper guide rails 11 and the lower guide rails 12, thereby achieving a more stable position of the carriers 2 in the working positions. In the end positions on one side of the carriers 2, the guide rollers 2 roll away. After the support strip 14, whose guide roller 2 and at the same time the other side of the carrier 2 support roller 2 engage the teeth of the support chain wheels 15, 16, which thus keep the carriers 2V stable even when the load is placed in the center of gravity of the carriage 4.
