Description

Technical Field

[0001] This utility model relates to the field of pallet conveying technology, and in particular to a pallet transfer conveying line. Background Technology

[0002] Pallet conveying can utilize roller conveyors or chain conveyors. Regardless of the method, pallet adjustments are necessary when a change in direction is required. However, both roller conveyors and chain conveyors are linear conveying devices and typically cannot perform changes in direction. Existing technology CN113233160B discloses a lifting and transferring pallet conveyor line, which uses a lifting method to transfer pallets. This method is not only cumbersome but also requires that the pallets not carry any goods, significantly limiting its application. Existing technology CN117142082A discloses a dual-pallet inbound / outbound conveying system, which combines a chain conveyor and a roller conveyor, inserting the chain conveyor into the roller conveyor to achieve pallet transfer. However, this structure can only be adjusted in a vertical 90-degree conveying direction; it cannot be applied to non-vertical conveying directions (e.g., a 120-degree angle). Summary of the Invention

[0003] To address the problems existing in the prior art, this utility model provides a pallet transfer conveyor line that solves the problem of pallet transfer in non-linear conveying directions.

[0004] To achieve the above objectives, the following technical solution is provided:

[0005] The pallet transfer conveyor line includes an input chain unit, an output chain unit, and a steering chain unit, each with three chains. The steering chain unit is positioned between the input and output chain units, forming an angle of 90-170 degrees between them. The steering chain unit includes a rotary drive disc and steering chains. The steering chains and their drive mechanism are fixedly mounted at the center of the rotary drive disc. Of the three chains in the steering chain, the two outer chains are shorter, and the middle chain is longer, creating a sharp angle at the edge of the rotary drive disc. At the point where the middle chain connects to the rotary drive disc of the steering chain unit, it contracts inward relative to the outer chains, forming an inner V-shape.

[0006] The width of the three tracks of the steering track is smaller than the width of the three tracks of the input track unit and the output track unit.

[0007] The steering track is equipped with photoelectric sensors for lateral signal acquisition at both ends.

[0008] When the three tracks of the steering track are connected to the three tracks of the input track unit, the middle track of the steering track is located inside the line connecting the ends of the tracks on both sides of the input track unit.

[0009] The rotary drive disk is driven by a motor and a reducer, and is transmitted through the meshing of a small gear and a large gear plate.

[0010] The input track unit and the output track unit are each equipped with a track drive mechanism.

[0011] The input end of the input track unit and the output end of the output track unit are respectively equipped with photoelectric sensors.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] The pallet transfer conveyor line provided by this utility model can turn the pallet through the steering chain unit and can turn at a large angle of more than 90 degrees. Each chain unit is equipped with three chains, so that the chain can have a better connection effect when the chains are connected and can avoid collisions with the pallet during the connection process.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Example

[0021] like Figure 1-4As shown, this utility model provides a pallet transfer conveyor line, including an input track unit 10, an output track unit 20, and a steering track unit 30. Each of the three track units has three tracks. The steering track unit 30 is arranged between the input track unit 10 and the output track unit 20, and the input track unit 10 and the output track unit 20 form an angle of 90-170 degrees. The steering track unit 30 includes a rotary drive disk 31 and a steering track 32. The steering track 32 and its drive mechanism are fixedly installed at the center of the rotary drive disk 31. Among the three tracks of the steering track 32, the tracks on both sides are short, and the track in the middle is long, thus forming a sharp angle shape at the edge of the rotary drive disk 31. Among the three tracks of the input track unit 10 and the output track unit 20, at the position where they connect with the rotary drive disk 31 of the steering track unit 30, the middle track is contracted inward relative to the tracks on both sides to form an inner V-shape.

[0022] The width of the three tracks of the steering track 32 is smaller than the width of the three tracks of the input track unit 10 and the output track unit 20.

[0023] The steering track 32 is equipped with photoelectric sensors at both the front and rear ends for lateral signal acquisition, which can confirm the position of the pallet.

[0024] When the three tracks of the steering track 32 are connected to the three tracks of the input track unit 10, the middle track of the steering track 32 is located inside the line connecting the ends of the tracks on both sides of the input track unit 10, so that when the pallet is transferred at the track connection position, the pallet will not collide with the connection position.

[0025] The rotary drive disk 31 is driven by a motor and a reducer, and the transmission is achieved through the meshing of a pinion and a large gear. The rotary drive disk 31 can also be driven by other conventional rotary drive methods.

[0026] The input track unit 10 and the output track unit 20 are respectively equipped with a track drive mechanism (usually a motor drives a reducer, which in turn drives the track transmission).

[0027] The input end of the input track unit 10 and the output end of the output track unit 20 are respectively equipped with photoelectric sensors.

[0028] Compared with the prior art, the advantages of this utility model are as follows:

[0029] The pallet transfer conveyor line provided by this utility model can realize the turning of pallets through the turning chain unit 30, and can achieve large-angle turning with a range of more than 90 degrees; each chain unit is equipped with three chains, so that the chain can have a better connection effect when the chains are connected to each other, and can avoid collisions with pallets during the connection process.
