Description

Technical Field

[0001] This invention belongs to the field of conveying equipment technology, and particularly relates to a workshop conveying system. Background Technology

[0002] Workshop conveyor systems are core logistics equipment in the manufacturing production process. Through diverse conveying units such as conveyor belts, rollers, AGVs (Automated Guided Vehicles), and overhead chains, combined with control systems and positioning technologies, they enable automated and continuous transfer of raw materials, semi-finished products, and finished products between various processes in the workshop (such as processing, assembly, testing, and warehousing). They can flexibly adapt to complex paths such as straight lines, turns, and lifts according to the production scenario, and are characterized by high efficiency, precision, labor saving, and controllability. They can significantly reduce manual handling costs, shorten production cycles, and reduce material loss. At the same time, they can be linked with management systems such as MES (Manufacturing Execution System) and ERP to support intelligent production scheduling and data traceability. They are a key infrastructure for modern workshops to achieve flexible production, improve capacity, and enhance management levels.

[0003] Currently, the most commonly used equipment in workshop conveying systems for small equipment or parts is the conveyor belt. As the core structure of the conveying system, it plays a very important role. However, most current conveyor belts are fixed structures, such as welded fixed roller lines or integrated molded belt conveyors. Their tracks and frames are fastened by welding or bolts, lacking modular disassembly and reconfiguration design. When production processes are adjusted or production line layouts are optimized, the fixed-spacing rollers cannot adapt to new material sizes, and the welded frames are difficult to disassemble and move. The original conveying system is completely inflexible and cannot be adapted. Enterprises need to invest a lot of manpower and resources to dismantle old equipment, re-lay tracks, or even replace the entire system due to compatibility issues. This not only takes several days to several weeks, causing production interruptions, but also incurs high modification and procurement costs. Moreover, the modified structure is still rigid, and subsequent production line adjustments require repeating the process. It cannot meet the flexible adaptation needs of modern manufacturing industries with multi-variety, small-batch production, which seriously restricts production efficiency and market response speed. Summary of the Invention

[0004] This invention provides a workshop conveying system designed to address the problems of traditional rigid conveyor lines in workshops, which, due to their fixed structure and lack of modular design, cannot flexibly adapt to production line process adjustments or layout optimizations.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0026] Please see Figure 1-6 The present invention provides a technical solution: a workshop conveying system, including multiple conveyor belt units, all of which have the same structure. One of the conveyor belt units includes two transversely arranged and symmetrical device side plates 1. A connecting block 2 is transversely fixedly connected in the middle between the two device side plates 1. Adjustment structures are provided at both ends of the inner surface of the two device side plates 1.

[0027] The structures of multiple adjustable distance structures are all the same. One of the adjustable distance structures includes multiple side sliding grooves 5 opened at the middle of one end of the inner surface of the device side plate 1 along the length direction. The sliding sliders are slidably connected to the inside of the multiple side sliding grooves 5. The outer ends of the multiple sliding sliders are fixedly connected to a sliding middle plate 6 arranged along the length direction of the device side plate 1. The upper and lower surfaces of the same end of the device side plate 1 are provided with side sliding grooves 13 along their length direction. The sliding sliders 14 are slidably connected to the inside of the two side sliding grooves 13. The inner surfaces of the multiple upper and lower side sliders are respectively fixedly connected to two sliding side plates 8.

[0028] The top and bottom of the inner surface of the sliding middle plate 6 are fixedly connected with internal racks 9 along its length. The inner surfaces of the two sliding side plates 8 are respectively fixedly connected with side racks 10 corresponding to the two internal racks 9. The inner surface of the device side plate 1, located between the side racks 10 and the internal racks 9, is rotatably connected with gear shafts 11. The outer surfaces of the two gear shafts 11 are fixedly connected with internal gears and external gears, and the two internal gears and external gears mesh with their corresponding internal racks 9 and side racks 10 respectively.

[0029] The outer ends of the two sliding middle plates 6 at the same end are laterally rotatably connected to a first movable roller 7. The outer ends of the two sliding side plates 8 at the same end and at the same height are laterally rotatably connected to a second movable roller 12. The middle part between the two device side plates 1 and above and below the two ends of the connecting block 2 are respectively laterally rotatably connected to a first fixed roller 3 and a second fixed roller 4.

[0030] In this embodiment, the conveyor belt unit is equipped with an adjustable length structure. Each unit can adjust its specific length through the adjustable length structure, thereby flexibly adapting to the requirements of different production lines. The internal gears on the two gear shafts 11 mesh with the two internal racks 9, and the two external gears mesh with the two side racks 10. The number of teeth on the internal gears is twice the number of teeth on the external gears. In actual operation, the adjustable length structure drives the sliding middle plate 6 to move laterally through the drive device. During its movement, the two internal racks 9 above and below its inner surface drive the two internal gears meshing with them to rotate. At the same time, the rotation of the two internal gears also drives the two internal gears meshing with them to rotate. The external gear of the shaft rotates, which in turn drives the two side racks 10 to move through the two external gears. Since the number of teeth of the internal gear is twice that of the external gear, the two side racks 10 will move synchronously with the side racks 9 in the opposite direction and with half the distance. This causes the sliding middle plate 6 and the two sliding side plates 8 to move in the same way. When the first movable roller 7 moves to the outward end, the two second movable rollers 12 will move to the inward end, and the sum of the distances that the two second movable rollers 12 move to the inward end is equal to the distance that the first movable roller 7 moves to the outward end. The same applies if the two rollers move inward. In this way, the overall length of the conveyor belt unit can be changed without replacing the conveyor belt 15.

[0031] Furthermore, a crossbeam 16 is laterally fixed between the two sliding middle plates 6 at the same end, and multiple cylinders 17 are laterally fixed between the two end surfaces of the connecting block 2 and the crossbeam 16 at the same end.

[0032] In this embodiment, a synchronizer is provided inside the connecting block 2, which can control multiple cylinders 17 to move synchronously. The movement of the piston rods of the multiple cylinders 17 can drive the cross frame 16 fixedly connected to the outer end to move, thereby driving the two sliding middle plates 6 fixedly connected to the cross frame 16 to move to achieve the purpose of adjusting the length of the conveyor belt unit.

[0033] Furthermore, a servo motor 26 is laterally fixedly connected to the upper outer surface of a device side plate 1. The output shaft of the servo motor 26 rotatably passes through the device side plate 1 and is fixedly connected to one end of a first fixed roller 3.

[0034] In this embodiment, toothed rings are provided on the outer surfaces of multiple first fixed rollers 3, and toothed grooves that are adapted to the toothed rings are provided on the inner surface of the conveyor belt 15. The first fixed rollers 3 are driven to rotate by the operation of the servo motor 26, thereby driving the conveyor belt 15 to move and completing the conveying operation of the processed products.

[0035] Furthermore, fixed side baffles 27 are fixedly connected to the middle of the upper surface of the two device side plates 1 along their length direction, and movable side baffles 28 are fixedly connected to the upper surface of the multiple sliding side plates 8 at both ends along their length direction.

[0036] In this embodiment, both the fixed side baffles 27 and the movable side baffles 28 on both sides serve to prevent items from falling off, thus protecting the items on the conveyor belt 15 and preventing them from falling off the sides of the conveyor belt 15.

[0037] Furthermore, both ends of the outer surfaces of the two device side plates 1 are laterally fixedly connected to first fixing seats 18, and the outer ends of the multiple first fixing seats 18 are hinged to first electrically controlled telescopic rods 19. The other ends of the multiple first electrically controlled telescopic rods 19 are hinged to support base plates 20. Both ends of the outer surfaces of the two device side plates 1 and the inner sides of the first fixing seats 18 are laterally fixedly connected to second fixing seats 22. The outer surfaces of the multiple first electrically controlled telescopic rods 19 are fixedly connected to hinge seats 23. The corresponding second fixing seats 22 and hinge seats 23 are hinged to second electrically controlled telescopic rods 24.

[0038] In this embodiment, the conveyor belt unit can also adjust its height by controlling the extension and retraction of multiple first electrically controlled telescopic rods 19 at both ends. At the same time, by adjusting the length of multiple second electrically controlled telescopic rods 24, the tilt angle of multiple first electrically controlled telescopic rods 19 can be adjusted, thereby enabling the conveyor belt unit to achieve the effect of tilting, thus improving its adaptability to different products.

[0039] Furthermore, a fixed bracket 25 is vertically fixedly connected to the middle of the outer surface of the two device side plates 1, and an anti-slip pad 21 is fixedly connected to the bottom of the multiple fixed brackets 25 and the multiple supporting base plates 20.

[0040] In this embodiment, the fixed bracket 25 provides support and enhances stability when the conveyor belt unit is set horizontally, while the multiple anti-slip pads 21 further improve the stability of a single unit.

[0041] Furthermore, the outer ends of the outer surfaces of the multiple sliding side plates 8 are all laterally fixedly connected with convex shafts 29, the outer surfaces of the multiple convex shafts 29 at one end are rotatably connected with latches 30, and the outer end surfaces of the multiple convex shafts 29 at the other end are all fixedly connected with anti-detachment blocks 32.

[0042] In this embodiment, the outer end of the latch 30 is provided with a latching groove 31 that is adapted to the convex shaft 29. By rotating the latch 30, its latching groove 31 can be inserted into the outside of the convex shaft 29 at one end of another conveyor belt unit, thereby connecting and fixing the two conveyor belt units. The anti-detachment block 32 plays an anti-detachment role and improves the stability after connection.

[0043] The working principle and usage process of this invention: After installation, the system consists of multiple conveyor belt units connected end-to-end to form the main conveying structure. Each conveyor belt unit is equipped with an adjustment mechanism. During actual operation, the adjustment mechanism drives the sliding middle plate 6 to move laterally via a drive device. During this movement, the two internal racks 9 above and below its inner surface drive the two internal gears meshing with them to rotate. Simultaneously, the rotation of the two internal gears drives the external gears coaxial with them to rotate. Then, the two external gears drive the two side racks 10 to move. Since the number of teeth of the internal gears is twice that of the external gears, the two side racks 10 will move synchronously with the side racks 9 in the opposite direction and with half the distance. This causes the sliding middle plate 6 and the two sliding side racks 10 to move. Plate 8 performs the same movement, so that when the first movable roller 7 moves outward, the two second movable rollers 12 move inward, and the sum of the distances the two second movable rollers 12 move inward is equal to the distance the first movable roller 7 moves outward, and vice versa. In this way, the overall length of the conveyor belt unit can be changed without replacing the conveyor belt 15. All conveyor belt units are placed without welding, thus forming multiple movable independent modules. When adjusting the production process or optimizing the production line layout, they can be flexibly adjusted, allowing the conveyor system to flexibly adapt to production line adjustments and multi-variety production. They can be combined and arranged as needed without interrupting production, while reducing modification and maintenance costs, improving space and utilization efficiency, and adapting to different material and scenario requirements.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
