Description

Technical Field

[0001] This utility model relates to the field of circulating line mechanism technology, and in particular to a jig circulating line mechanism. Background Technology

[0002] In the field of online door panel processing, the circulating line structure is an important piece of equipment for achieving efficient and continuous door panel processing. The fixture carries the door panel and moves it along the circulating line to complete a series of processing steps. Currently, most existing circulating lines adopt a structure set on the same horizontal plane. This conventional design facilitates the layout of processing equipment and the unified management of operating procedures.

[0003] However, as door panel sizes continue to increase, especially for wider door panels transported on the circulation line, the width of the circulation line has to be increased due to the limitations of the circulation line layout on the same horizontal plane. This results in a significant increase in the space occupied by the circulation line, which not only increases the cost of factory construction and equipment layout, but also reduces the utilization rate of the space, restricts the compact and efficient layout of the production line, and brings many inconveniences and economic burdens to the company's production planning and operation management. Utility Model Content

[0004] The purpose of this utility model is to provide a fixture circulation line mechanism to address the defects and shortcomings of the existing technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] The present invention provides a fixture circulation line mechanism, comprising a main conveyor line and a carrier; a lifting conveyor is provided on both sides of the main conveyor line; the main conveyor line includes a frame, an upper roller assembly, and a lower conveyor line; the lower conveyor line is used to transport the carrier between the two lifting conveyors.

[0007] The upper roller assembly and the lower conveyor line are arranged sequentially along the height direction;

[0008] The lifting conveyor is used to transport the carrier between the upper roller assembly and the lower conveyor line.

[0009] Furthermore, the upper roller assembly consists of two sets of roller groups; the two sets of roller groups are respectively arranged on both sides of the frame; each roller group consists of multiple upper guide rollers; the upper guide rollers are evenly arranged along the length of the frame; and main side baffles are fixed on both sides of the frame.

[0010] Furthermore, the lifting conveyor includes a lifting frame and a base support; a lifting assembly connects the lifting frame and the base support; and an external conveyor line is installed on the lifting frame.

[0011] Side baffles are provided on both sides of the lifting frame; a rear baffle is fixed at the end of the lifting frame away from the main conveyor line.

[0012] Furthermore, the lifting assembly includes a lifting cylinder and two folding rod groups symmetrically arranged on both sides of the base support; each folding rod group consists of two supporting folding rods; the shafts of the two supporting folding rods are hinged to each other; the two supporting folding rods in the same folding rod group are the first folding rod and the second folding rod, respectively.

[0013] One end of the first folding rod is hinged to the base support; the other end of the first folding rod is slidably connected to the lifting frame; one end of the second folding rod is slidably connected to the base support; the other end of the second folding rod is hinged to the lifting frame.

[0014] The two ends of the lifting cylinder are respectively hinged to the base support and the lifting frame.

[0015] Furthermore, multiple buffer cylinders are evenly distributed on the base support; a buffer pad 9 is fixed to the piston rod end of the buffer cylinder.

[0016] Furthermore, the carrier consists of two parallel connecting rods and multiple crossbeam assemblies disposed between the two connecting rods; the two ends of the crossbeam assemblies are respectively fixed to the two connecting rods.

[0017] Furthermore, the crossbeam assembly consists of an inner tube and an outer tube; the inner tube is slidably connected inside the outer tube; one end of the inner tube extending outside the outer tube is fixed to one of the connecting rods; the outer tube is fixed to another connecting rod; and the crossbeam assemblies are arranged parallel to each other.

[0018] With the above structure, the beneficial effects of this utility model are as follows: The carrier is used to support and hold the door panel. During the processing of the door panel, the carrier and the door panel move together on the upper roller assembly. After the door panel is processed on the line and removed from the carrier, the carrier first enters the lifting conveyor on one side. Then, the lifting conveyor drives the carrier down to connect with the lower conveyor line, pushes the carrier onto the lower conveyor line, and sends the carrier back to the lifting conveyor on the other side. The lifting conveyor on the other side lifts the carrier returned from the lower conveyor line to the same height as the roller assembly and pushes the carrier onto the upper roller assembly, forming a cycle of the carrier. In this structure, the upper roller assembly and lower conveyor line are arranged vertically and vertically, and there are two lifting conveyors that can lift and lower the carrier, so that the upper roller assembly and lower conveyor line are stacked at different heights in the same position, reducing the footprint of the circulation line and improving the space utilization rate.

[0031] The present invention will be further described below with reference to the accompanying drawings.

[0032] like Figures 1 to 6 As shown, the fixture circulation line mechanism of this utility model includes a main conveyor line 2 and a carrier 3; both sides of the main conveyor line 2 are provided with lifting conveyors 1; the main conveyor line 2 includes a frame 203, an upper roller assembly and a lower conveyor line 204; the lower conveyor line 204 is used to transport the carrier 3 between the two lifting conveyors 1.

[0033] The upper roller assembly and the lower conveyor line 204 are arranged sequentially along the height direction;

[0034] The lifting conveyor 1 is used to transport the carrier 3 between the upper roller assembly and the lower conveyor line 204;

[0035] The lower conveyor line 204 is not fundamentally different from existing conveyor line technology, so it will not be discussed in detail.

[0036] The carrier 3 is used to support and hold the door panel. During the processing of the door panel, the carrier 3 moves together with the door panel on the upper roller assembly. After the door panel is processed on the line and removed from the carrier 3, the carrier 3 first enters the lifting conveyor 1 on one side. Then, the lifting conveyor 1 drives the carrier 3 down to dock with the lower conveyor line 204, pushing the carrier 3 onto the lower conveyor line 204. The lower conveyor line 204 sends the carrier back to the lifting conveyor 1 on the other side. The lifting conveyor 1 on the other side lifts the carrier 3 returned from the lower conveyor line 204 to the same height as the roller assembly and pushes the carrier 3 onto the upper roller assembly, forming a carrier cycle. In this structure, the upper roller assembly and the lower conveyor line 204 are arranged vertically and vertically, and the two lifting conveyors 1 that can lift and lower the carrier 3 allow the upper roller assembly and the lower conveyor line 204 to be stacked at different heights in the same position, reducing the footprint of the cycle line and improving the space utilization rate.

[0037] In a preferred embodiment of this utility model, the upper roller assembly consists of two sets of roller groups; the two sets of roller groups are respectively arranged on both sides of the frame 203; each roller group consists of multiple upper guide rollers 201; the upper guide rollers 201 are evenly arranged along the length of the frame 203; and main side baffles 202 are fixed on both sides of the frame 203.

[0038] The carrier 3 is placed between the two main side baffles 202 and guided and limited by the main side baffles 202. The bottom of the carrier 3 is supported on the top of the upper guide roller 201, so that the carrier 3 and the door panel can slide freely between the main side baffles 202 along the length of the frame 203. The door panel or the carrier 3 can slide smoothly by gently pushing it manually.

[0042] When the carrier 3 enters the outer conveyor 105 on the other side from the lower conveyor line 204, the lifting assembly drives the lifting frame 106 to move, so that the outer conveyor line 105 and the carrier 3 rise to be aligned with the upper roller assembly. Then the outer conveyor line 105 pushes the carrier 3 from the lifting frame 106 onto the upper roller assembly.

[0046] The lifting cylinder 102 is activated to drive the lifting frame 106 to move up and down, thereby changing the height of the lifting frame 106. The support folding rod 101 is used to support the lifting frame 106 parallel, ensuring that the lifting frame 106 is always in a horizontal state.

[0047] In a preferred embodiment of this utility model, a plurality of buffer cylinders 108 are evenly distributed on the base support 107; a buffer pad 109 is fixed to the piston rod end of the buffer cylinder 108; when the lifting frame 106 descends, the buffer pad 109 and the buffer cylinder 108 are used to limit the lifting frame 106 and provide support and buffering.
