Conveyor transfer device {A CONVEYER TRANSPORTATION APPARATUS}

The present invention relates to a conveyor transport device, and in particular, performs loading and unloading operations of goods, and is composed of a roller conveyor structure capable of withdrawing and retracting a transport table from a frame, so that normal loading and unloading operations are not performed. Otherwise, the overall length of the conveyor can be shortened to easily secure a passage for pedestrians, and the structural characteristics of the frame arranged at an inclined angle, one side of which is higher than the other side, can be used to retract the conveyor during the retraction operation. The present invention relates to a conveyor transfer device having an improved structure so that the conveyor transfer unit is smoothly moved without operating noise and the overall length of the conveyor transfer unit is easily adjusted by being operated in a sliding manner by its own weight.

In general, a conveyor is designed to automatically transport an object to be transported by a belt, roller, or chain extending to a certain length, and is usually operated in the form of an endless track circulating a certain path to load or unload the object to be conveyed.

Such a conveyor automatically transports products or raw materials in a manufacturing process or logistics work, etc., and is usually provided to form a certain path on a plane or to extend upward at a certain inclination angle.

The article is intended to be transported while resting on the transport belt. One of the characteristics of the conventional conveyor device is that the length can be adjusted. This is extremely useful when, for example, it is necessary to adjust the transport distance according to different situations, such as moving goods around obstacles such as ditches.

In addition, it is advantageous to reduce the length even when moving the conveyor device, but the conventional conveyor device has an advantage in this regard.

As a method of adjusting the length of the conveyor device, a hinge is installed in the middle and a foldable method or a method of sliding and withdrawing the frame like an antenna has been proposed.

However, it is natural that the length of the conveyor belt should be adjusted according to the change in the length of the conveyor, but the length of the conveyor belt could not be adjusted according to the length of the frame. Therefore, when it is desired to reduce the length of the conveyor by providing a separate tension control means, the tension of the transfer belt is properly maintained by operating the tension control means together.

As the conventional prior art related to the existing conveyor device, as disclosed in Korean Patent Registration No. 10-1111620 "Foldable Conveyor Device for Carrying Goods" (Registration Date: 2012.01.26), A first frame forming a frame; a first transport belt installed on the first frame; a second frame that forms a quadrangular frame by the second crossbar and the second vertical bar, and is hingedly connected to one end of the first frame; a second transfer belt installed on the second frame; a third frame formed by a third crossbar and a third vertical bar to form a quadrangular frame, and connected by a hinge to the other end of the first frame; a third transport belt rotatably installed on the third frame in an endless orbit; a driving motor for driving the first conveying belt; It includes a power transmission means for enabling the first, second and third transfer belts to be interlocked with each other and rotated in the same direction at the same time by the driving force of the driving motor.

Another prior art related to the existing conveyor device is a pair of left and right rollers having a plurality of rollers along the longitudinal direction, as disclosed in Korean Utility Model Registration No. 20-425451 "Foldable Conveyor" (registration date: 2006.08.29). a conveyor member; A spacing control bar provided in the same longitudinal direction between them; A plurality of connecting bars for hinge-connecting the conveyor members so that the width of the conveyor member can be adjusted around the spacing control bar; And it is configured to include a locking means for fixing and releasing the width-adjusted conveyor member provided in the spacing control bar.

However, according to the prior art, it was too inconvenient to operate the length control and tension control means of the conveyor.

In addition, the configuration of the conveyor device is complicated, the weight is increased, and there are disadvantages that increase the production cost.

In addition, in the case of a foldable conveyor, since it is a two-stage fold, there is a limit to reducing the volume and there is no significant effect.
