Description

Technical Field

[0001] This utility model relates to the field of logistics automation technology, and in particular to a pneumatic centering mechanism for a box-type conveyor line. Background Technology

[0002] In the logistics automation industry, box conveyor lines are one of the main methods of product transportation, widely used in warehousing, sorting, and production lines. On the same box conveyor line, it is often necessary to transport multiple products of different specifications simultaneously, with transport trolleys delivering them to designated storage locations.

[0003] However, in practice, it has been found that due to differences in the dimensions and other aspects of products of different specifications, their positions may not be consistent when transported on the same box conveyor line, and they may even shift or tilt. This instability in position makes it difficult for the transport trolley to accurately grasp the product when docking with the conveyor line and picking it up, resulting in the center of gravity deviating from the intended support area. In severe cases, this may cause the product to become unbalanced and fall during transfer, causing product damage, equipment failure, or even production line interruption, affecting overall logistics efficiency and system safety.

The rotating plate is rotatably connected to the fuselage support via the bearing assembly, which is a deep groove ball bearing. Both ends of the rotating plate are hinged to the connecting rod assembly via spherical plain bearings.

[0019] Furthermore, the execution component includes two symmetrically arranged center plates, and multiple push plates are spaced apart at the bottom of the center plates. The push plates are detachably connected to the center plates by bolts.

[0035] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0036] This specific embodiment discloses in detail a pneumatic centering mechanism for a box-type conveyor line, such as... Figures 1 to 3 As shown, it includes an execution component 1, a drive unit 2, a transmission component 3, a guide component 4, and a body support 5. The body support 5 includes two opposing support seats 51, and a rotating plate mounting seat 52 is fixedly disposed between the two support seats 51.

[0037] The drive unit 2 includes a cylinder 21 and a solenoid valve 22, with the cylinder 21 and the solenoid valve 22 connected via an air circuit. The tail of the cylinder 21 is fixedly mounted on one of the support bases 51 via a cylinder bracket 211. The output end of the cylinder 21 is connected to the transmission assembly 3 via a connecting connector 212.

[0038] The transmission assembly 3 is a linkage-type transmission mechanism, including a rotating component 31 and two sets of symmetrically arranged linkage assemblies 32. The rotating component 31 is mounted on the rotating plate mounting base 52, specifically including a rotating plate 311 and a bearing assembly 312. The rotating plate 311 is rotatably connected to the rotating plate mounting base 52 via the bearing assembly 312, which preferably uses a deep groove ball bearing. One end of the rotating plate 311 is connected to the output end of the cylinder 21 via the connecting joint 212, and its two ends are respectively hinged to one end of the corresponding linkage assembly 32 via spherical plain bearings 313. The other end of the linkage assembly 32 is hinged to the actuating component 1.

[0039] The execution component 1 includes two symmetrically arranged center plates 11, located on both sides of the conveyor line. Each center plate 11 has multiple push plates 12 spaced apart along the conveying direction at its bottom, preferably six. The push plates 12 are detachably connected to the center plates 11 by bolts. Reinforcing ribs 121 are provided on the inner side of each push plate 12, i.e., the side facing the product, to enhance its structural strength.

[0040] The guide assembly 4 is symmetrically arranged in two sets, each set including a guide shaft 41 perpendicular to the conveying direction and a linear bearing 42 cooperating with the guide shaft 41. The two ends of the guide shaft 41 are respectively fixed to the two support seats 51. The centering plate 11 of the execution assembly 1 is mounted on the guide shaft 41 via the linear bearing 42, allowing the centering plate 11 to move horizontally along the guide shaft 41 in a direction perpendicular to the conveying direction.

[0041] The working principle is as follows:

[0042] When the product is transported to the designated center position by the conveyor line, the position sensor (not shown in the diagram) detects the product's arrival signal, and the control system immediately issues a command. The solenoid valve 22 is energized, switching the airflow direction and driving the cylinder 21 to retract the piston rod.

[0043] The piston rod drives the rotating plate 311 to rotate around its axis via the connecting joint 212, supported by the bearing assembly 312. Since the two ends of the rotating plate 311 are respectively hinged to two sets of connecting rod assemblies 32 via spherical bearings 313, the rotation of the rotating plate 311 causes the two sets of connecting rod assemblies 32 connected to it to swing synchronously in opposite directions.

[0044] The swing of the linkage assembly 32 converts rotational motion into linear motion through the hinge point between its other end and the centering plate 11 of the actuator assembly 1. Specifically, the rotation of the rotating plate 311 pushes or pulls the linkage assemblies 32 on both sides, thereby causing the centering plates 11 on both sides to move synchronously and in opposite directions along the guide shaft 41 fixed on the support base 51 under the constraint of the guide assembly 4. The direction of motion is perpendicular to the conveying direction.

[0045] As the centering plate 11 moves towards each other, the pusher plate 12 fixed thereon moves simultaneously from both sides of the conveyor line towards the center until it comes into close contact with both sides of the product and applies clamping force. The reinforcing ribs 121 on the inner side of the pusher plate 12 ensure the structural strength and stability of the pusher plate during the clamping process. This clamping force forces the product, which may be misaligned, to be pushed until its centerline coincides with the theoretical centerline of the conveyor line, achieving precise centering positioning.

[0046] After the product completes centering, the control system receives a positioning completion signal or, according to a preset time, the solenoid valve 22 switches the air path direction again, driving the piston rod to extend. The extended piston rod drives the rotating plate 311 to rotate in the opposite direction via the connecting joint 212. The reverse rotation of the rotating plate 311, in turn, drives the centering plates 11 and push plates 12 on both sides to move synchronously in opposite directions along the guide shaft 41 via the connecting rod assembly 32, quickly disengaging from both sides of the product and releasing the clamping state. At this point, the product, which has completed centering correction, can continue to be smoothly conveyed along the conveyor line to the next process. The entire centering process is fast, accurate, and stable, effectively eliminating the risk of product position deviation and tilting.
