Description

TECHNICAL FIELD

[0001] The utility model relates to automatic production equipment technical field, specifically, it shows a fork conveying mechanism and fork conveying production line. BACKGROUND

[0002] In the 3C automatic production equipment, the conveyor equipment is often used in the situation of the step-by-step continuous movement of products. In the common conveyor, although the belt conveyor mechanism and the chain conveyor mechanism can realize the continuous conveying of products, the synchronization of the products is poor in the product conveying process, the products cannot be accurately conveyed to the processing station step by step, and even the movement interference occurs, causing the problem that the production line cannot work normally. UTILITY MODEL CONTENT

[0003] One of the purposes of the utility model is to provide a fork conveying mechanism, which can continuously move a plurality of products to be processed step by step, and the relative positions of the products are constant.

[0004] The technical scheme is as follows:

[0005] A fork conveying mechanism, which comprises a product chute and a rack for placing the product chute; a carrier is arranged below the product chute and driven by a telescopic mechanism to move up and down, a plurality of upward extending forks are arranged on the carrier along the length direction of the carrier; a pushing mechanism is further arranged at the rack, the telescopic mechanism and the carrier are driven by the pushing mechanism to move horizontally and reciprocally in the same direction as the product chute, and a space is reserved on the product chute for the vertical and horizontal movement of the fork group.

[0006] The products to be processed in batches enter the product chute, the telescopic mechanism controls the fork group on the carrier to be inserted into the area of the product chute, one fork group corresponds to one product, and then the telescopic mechanism and the carrier are controlled by the pushing mechanism to move towards the conveying direction of the production line, so that the fork group can push the product to the next station. During the product conveying process, the relative positions of the products do not change, which facilitates the accurate control of the products by the subsequent station.

[0007] Optionally, the product chute comprises a pair of blocking rails and a pair of conveying rails, the blocking rails are parallel to the conveying rails and the conveying rails are located on the inner side, and the arrangement height of the blocking rails is higher than that of the conveying rails. The pair of blocking rails are used to constitute the design of limiting the flow direction of the products, so as to ensure the consistency of the conveying direction of the products, and the pair of conveying rails are used as the carrier for continuously conveying the products. Compared with the whole plane conveying mode of the existing conveyor, the stability is better, the effect of carrying the products is good, and the manufacturing cost is low.

[0008] In the shifting fork conveying mechanism as described above, the upper end surface of the conveying rail is in the shape of a circular arc. The area of the top surface of the conveying rail in contact with the bottom surface of the product is reduced, thereby reducing the friction during the sliding of the product relative to the conveying rail, and facilitating the stable conveying of the product.

[0009] In the shifting fork conveying mechanism as described above, the pair of blocking rails and the pair of conveying rails are symmetrically distributed on both sides of the shifting fork group respectively. This ensures that the position of the shifting fork in shifting the product is accurately located at the center position on both sides of the product, so that the movement direction of the product on the conveying rail is always kept as a straight line.

[0010] Optionally, the telescopic mechanism includes a plurality of groups of vertically arranged telescopic cylinders, the main body part of the telescopic cylinder is arranged on the pushing mechanism, and the telescopic end of the telescopic cylinder is connected to the carrier. The telescopic cylinder controls the upward movement of the carrier, and after pushing a batch of products to the next station, the telescopic cylinder controls the shifting fork on the carrier to move downward away from the product slide area, waiting for the pushing action of the next batch of products, realizing intermittent cyclic reciprocating action.

[0011] Optionally, the pushing mechanism includes a fixed slide, a balance slide rail in sliding connection with the fixed slide, and a driving member driving the balance slide rail to move horizontally relative to the product slide, and the telescopic mechanism is arranged on the balance slide rail. In this way, the telescopic mechanism and the carrier can be moved left and right together by the driving member, thereby realizing the horizontal reciprocating movement of the shifting fork, so as to realize the step-by-step pushing of the product.

[0012] Optionally, the shifting fork group includes a rectangular frame composed of four prongs, and the inner side wall surface of the top end of the prong is in the shape of an arc. The rectangular frame composed of four prongs can just clamp the product, so that the shifting fork group can surround the product from bottom to top and drive the product to move together, and the design of the arc-shaped inner side wall surface of the top end of the prong helps to quickly realize the positioning with the product.

[0013] Optionally, the rack is composed of a plurality of groups of supporting frames opposite to each other, and the supporting frame is provided with mounting blocks having a height difference at both ends, and the mounting block is designed to constitute the product slide.

[0014] Optionally, the two sides of the rack are also respectively provided with a pair of sensors for sensing whether there is a product on the product slide. The presence or absence of the product on the product slide is sensed by the pair of sensors.

[0015] Another purpose of the utility model lies in providing a fork conveying production assembly line, including a plurality of groups of front and back spliced table body, wherein, the table body is installed fork conveying mechanism as described above, mutual splicing between adjacent fork conveying mechanism.

[0016] Compared with the prior art, the utility model has the beneficial effects that:

[0017] 1, the vertical motion of fork group is realized by telescopic mechanism, the telescopic mechanism and the carrier are controlled to reciprocate left and right by pushing mechanism, so that the horizontal motion of fork group is realized, and then the repeated progressive feeding action of product is realized by fork group, which is simple in structure, small in occupied space and simple in design, and can meet the use demand of multiple scenes.
