Description

Technical Field

[0001] The present invention relates to the technical field of assembly lines, and specifically to a speed chain assembly line capable of multi-station transfer and material receiving. Background Art

[0002] A speed chain assembly line is a conveying mechanism for material conveying in assembly and processing production lines. Its conveying principle is to utilize the speed increasing function of the speed chain to enable the work loading plates carrying goods thereon to run quickly, and stop at corresponding operating positions through stoppers; or complete accumulation, transfer, transposition, dedicated line and other functions through corresponding instructions. Due to the advantages of large conveying capacity, capable of carrying larger loads, accurate and stable conveying speed, and ensuring precise synchronous conveying, the speed chain assembly line has been widely promoted and used.

[0003] Chinese Patent Publication No. CN103213818B discloses "a speed chain assembly line", which includes a workbench and lifting mechanisms arranged at both ends of the workbench. The workbench includes an upper load plate line and a lower return plate line provided with speed chains, and work loading plates running on the speed chains. The two ends of the upper load plate line and the lower return plate line are docked through lifting mechanisms. The work loading plates realize left and right movement through the speed chains and up and down movement through the lifting mechanisms. The upper load plate line and the lower return plate line are parallel and offset from each other up and down. By arranging the upper load plate line and the lower return plate line parallel and offset from each other up and down, the lower return plate line has a space conducive to the human body to perform sitting operations, avoiding the fatigue of standing for a long time in the existing speed chain assembly line, reducing the labor intensity, being highly practical, having a simple structure, and realizing a more user-friendly working environment.

[0004] During the conception process, the applicant retrieved a large number of patent documents on the patent network. For example, when "a speed chain assembly line" disclosed in Chinese Patent Publication No. CN103213818B is in use, the conveying and transfer rates are mostly fixed. When conveying some materials that need secondary processing on the assembly line, since the working time required for secondary processing may be relatively long and the work efficiency of each staff member is not equal, the fixed conveying rate may lead to a situation where the material in the staff's hand has not been processed yet, and the next material has already been conveyed, disrupting the work rhythm and thus affecting the work efficiency. In addition, there are fewer transfer stations, which may cause untimely material processing and thus affect the production progress. Therefore, a speed chain assembly line capable of multi-station transfer and material receiving is proposed to solve the above-mentioned problems. Summary of the Invention

[0015] (III) Beneficial effects Compared with the prior art, the present invention provides a double-speed chain production line capable of transferring and receiving materials at multiple stations, which has the following beneficial effects: 1. The double-speed chain assembly line capable of transferring and receiving materials at multiple stations can enable the staff to transfer materials according to their own work rhythm through the setting of the material transfer device. When the staff is operating, the material transfer device is not started. When the staff completes the processing of the existing material, the material transfer device is started to transfer the next material. Through the setting of multiple secondary conveying units and the material transfer device, the effect of transferring materials on the main conveying unit at multiple stations is achieved, which improves the efficiency of transferring and processing materials. In addition, the staff can adjust the material transfer rhythm by themselves, which can avoid the situation where some staff members fail to handle the materials in time due to the fixed-speed transportation of the assembly line, thereby affecting the overall work. Through the setting of the tray assembly, the staff can rotate the materials by rotating the turntable when processing the materials, making the materials easier to process, simplifying the work steps, avoiding the need to adjust their own position due to processing at various angles during processing, thereby affecting work efficiency, and increasing work intensity. When the tray assembly is being transported, the turntable cannot be rotated through the cooperation of the resistance rod and the limit block, which avoids the unstable placement of materials due to the rotation of the turntable during transportation.

[0016] 2. The double-speed chain assembly line capable of multi-station transfer and material receiving, through the setting of the auxiliary device, makes it more convenient for the staff to pick up tools and parts during the processing. And through the classification and placement of parts and tools in multiple storage compartments according to specifications, it can reduce the situation that the work efficiency is affected by the inability to find tools and parts during work, improving the work efficiency of the staff. Through the setting of two cover plates, after the material processing is completed and the tool box descends, the two cover plates automatically merge. The merged cover plates can block the tools and parts in the tool box, preventing foreign objects from falling into the tool box during transportation. When the next processing operation is carried out and the tool box rises, driving the two cover plates to open, the cover plates can protect the secondary conveyor units below the front and rear sides of the tool box, preventing the staff from accidentally dropping small parts into the secondary conveyor units during processing, resulting in an increased probability of secondary conveyor unit failures. Through the setting of multiple elastic pieces and four lever rods, during the movement of the tool box, the multiple elastic pieces drive the tool box to vibrate, and the tool box vibrates the tools and parts inside the multiple storage compartments evenly, facilitating the next pick-up by the staff.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example 1 See also Figures 1-4, a double-speed chain assembly line capable of multi-station transfer and material receiving, comprising: a main conveyor unit 1 for conveying materials; a secondary conveyor unit 2 for diverting and transferring the materials on the main conveyor unit 1; the secondary conveyor unit 2 is arranged on the left side of the main conveyor unit 1, there are multiple secondary conveyor units 2, each secondary conveyor unit 2 is equipped with a material transfer device 3 and an auxiliary device 4, a tray assembly 39 is placed on the main conveyor unit 1, there are multiple tray assemblies 39, materials are placed on the tray assemblies 39, and the multiple tray assemblies 39 are placed on the main conveyor unit 1. When the main conveyor unit 1 and the secondary conveyor unit 2 are started, the main conveyor unit 1 drives the multiple tray assemblies 39 above it to move forward.The material transfer device 3 is used for transferring materials. The material transfer device 3 is arranged inside the main conveyor unit 1. The material transfer device 3 includes a hydraulic cylinder 31. The hydraulic cylinder 31 is installed on the ground. The output end of the hydraulic cylinder 31 is connected with a mounting seat 32. Two rotating shafts 33 are rotatably installed on the inner wall of the mounting seat 32. Two material transfer belts 34 are sleeved on the outer walls of the two rotating shafts 33. The hydraulic cylinder 31 drives the mounting seat 32 to move upward. The mounting seat 32 drives the two rotating shafts 33 to move upward. The two rotating shafts 33 drive the two material transfer belts 34 to move upward. During the upward movement of the two material transfer belts 34, the tray assembly 39 will be lifted, so that the tray assembly 39 loses the connection relationship with the main conveyor unit 1. A connecting frame 35 is connected to the bottom of the mounting seat 32. A toothed shaft 37 is rotatably installed on the inner wall of the connecting frame 35. Two belts 36 are sleeved on the toothed shaft 37. Both of the two belts 36 are sleeved on one of the rotating shafts 33. A rack 38 is installed on the main conveyor unit 1. The rack 38 meshes with the toothed shaft 37. The mounting seat 32 drives the connecting frame 35 to move upward. The connecting frame 35 drives the toothed shaft 37 to move upward. During the upward movement of the toothed shaft 37, it rotates through the cooperation with the rack 38. When the toothed shaft 37 rotates, it drives one of the rotating shafts 33 to rotate through the two belts 36. The rotating shaft 33 drives the two material transfer belts 34 to rotate, so that while the two material transfer belts 34 lift the tray assembly 39 upward, they can also drive the tray assembly 39 to move leftward through their own rotation. One end of the connecting frame 35 away from the mounting seat 32 is connected with a material receiving seat 310. A first telescopic rod 311 is connected to the bottom of the material receiving seat 310. The bottom of the first telescopic rod 311 is installed on the ground. Guide wheels 312 are installed on the secondary conveyor unit 2. During the leftward movement of the tray assembly 39, it moves onto the material receiving seat 310 under the guidance of the guide wheels 312. Through the setting of the material transfer device 3, the staff can transfer materials according to their own work rhythm. When the staff is operating, the material transfer device 3 does not start. When the staff has completed the processing of the existing materials, the material transfer device 3 is started to transfer the next material. Through the setting of multiple secondary conveyor units 2 and the material transfer device 3, the effect of transferring the materials on the main conveyor unit 1 at multiple workstations is achieved, improving the efficiency of transferring and processing materials. And by the staff adjusting the transfer rhythm by themselves, it is possible to avoid the situation that some staff cannot handle in time due to the fixed-speed transportation of the assembly line, thus affecting the overall work.

[0021] Furthermore, please refer to Figure 4, the tray assembly 39 includes a chassis 391, on which a turntable 392 is rotatably mounted. Four abutting rods 393 are slidably mounted on the inner wall of the chassis 391. One end of the four abutting rods 393 close to the center of the chassis 391 is connected to the inner wall of the chassis 391 through springs. Four limiting blocks 394 are slidably mounted on the inner wall of the chassis 391. Four limiting grooves are formed at the bottom of the turntable 392. The four limiting blocks 394 are respectively located on the movement tracks of the four abutting rods 393. The four limiting grooves at the bottom of the turntable 392 are respectively located on the movement tracks of the four limiting blocks 394. When the chassis 391 comes into contact with the main conveyor unit 1 or the secondary conveyor unit 2, two of the four abutting rods 393 are pushed by the reaction force of the main conveyor unit 1 or the secondary conveyor unit 2 and move towards the limiting blocks 394 and come into contact with the limiting blocks 394. When the abutting rod 393 comes into contact with the limiting block 394, the abutting rod 393 will push the limiting block 394 upwards. After the limiting block 394 is pushed upwards into the limiting groove of the turntable 392, the limiting block 394 has a limiting effect on the turntable 392. When the chassis 391 does not come into contact with the main conveyor unit 1 or the secondary conveyor unit 2, the four abutting rods 393 are reset due to the elastic force of the springs, and the limiting blocks 394 are reset by their own gravity. At this time, the limiting blocks 394 lose the limiting effect on the turntable 392, so that when the chassis 391 is lifted, the turntable 392 can rotate, and when the chassis 391 is being transported, the turntable 392 is limited and cannot rotate. Through the setting of the tray assembly 39, when the staff processes the materials, the materials can be rotated by rotating the turntable 392, making the materials more convenient to process, simplifying the working steps, avoiding adjusting their own positions when processing each angle, thus affecting the work efficiency and increasing the work intensity. When the tray assembly 39 is being transported, through the cooperation of the abutting rods 393 and the limiting blocks 394, the turntable 392 cannot rotate, avoiding the materials from being placed unstably due to the rotation of the turntable 392 during transportation.

[0022] In this embodiment, the auxiliary device 4 is used to assist the staff in processing operations.

[0023] Please refer to Figures 5-8, the auxiliary device 4 is arranged inside the secondary conveying unit 2. The auxiliary device 4 includes a fixing member 41 which is installed at the bottom of the material receiving seat 310. One end of the fixing member 41 away from the material receiving seat 310 is installed with a tool box 42. The bottom of the fixing member 41 is connected with a second telescopic rod 43 which is installed on the ground. A plurality of storage compartments 44 are installed in the tool box 42. The staff places various tools and parts required for processing in an orderly manner by category and specification in the plurality of storage compartments 44 of the tool box 42 in advance. During the processing operation by the staff, since the tool box 42 is located beside the tray assembly 39, it is more convenient for the staff to pick up. Through the setting of the auxiliary device 4, it is more convenient for the staff to pick up tools and parts during the processing. Moreover, by classifying and placing parts and tools in different specifications in the plurality of storage compartments 44, the situation of affecting work efficiency due to the inability to find tools and parts during work can be reduced, thus improving the work efficiency of the staff.

[0024] Furthermore, please refer to Figure 8 , two cover plates 45 are slidably installed on the tool box 42. Two scissor rods 46 are respectively hinged on the two cover plates 45. The inner walls of the two scissor rods 46 are hinged together. A sleeve block 47 is installed on the secondary conveying unit 2. The inner wall of the sleeve block 47 is slidably connected with the two scissor rods 46. When the tool box 42 moves downward, the tool box 42 drives the two cover plates 45 to move downward. The two cover plates 45 drive the two scissor rods 46 to move downward. During the downward movement of the two scissor rods 46, due to the extrusion of the sleeve block 47, the upper segments of the two scissor rods 46 move towards each other. During the movement of the two scissor rods 46, they drive the two cover plates 45 to merge. When the two scissor rods 46 move upward, through the extrusion of the sleeve block 47, the two scissor rods 46 drive the two cover plates 45 to open. Through the setting of the two cover plates 45, after the material processing is completed and the tool box 42 descends, the two cover plates 45 automatically merge. The merged cover plates 45 can shield the tools and parts in the tool box 42 to prevent foreign objects from falling into the tool box 42 during transportation. When the next processing operation is carried out and the tool box 42 rises to drive the two cover plates 45 to open, the cover plates 45 can protect the secondary conveying unit 2 below the front and rear sides of the tool box 42, preventing the staff from accidentally dropping small parts into the secondary conveying unit 2 during processing, which may increase the probability of failure of the secondary conveying unit 2.

[0025] Still further, please refer to Figures 6-7, a plurality of elastic pieces 48 are installed on the outer wall of the tool box 42, and four lever rods 49 are installed on the secondary conveyor unit 2. The four lever rods 49 are respectively located on the movement tracks of the plurality of elastic pieces 48. During the downward movement of the tool box 42, the plurality of elastic pieces 48 are driven to move downward. During the downward movement of the plurality of elastic pieces 48, they will respectively contact the four lever rods 49 and vibrate, causing the plurality of elastic pieces 48 to drive the tool box 42 to vibrate. Through the arrangement of the plurality of elastic pieces 48 and the four lever rods 49, during the movement of the tool box 42, the plurality of elastic pieces 48 drive the tool box 42 to vibrate, and the tool box 42 vibrates the tools and parts inside the plurality of storage compartments 44 evenly, facilitating the next taking by the staff.

[0026] The electrical components appearing in this article are all electrically connected to the external main controller and 220V mains power, and the main controller can be a conventional known device such as a computer for control.

[0027] Working principle: Materials are placed on the pallet assembly 39, and multiple pallet assemblies 39 are placed on the main conveyor unit 1. The main conveyor unit 1 and the secondary conveyor unit 2 are started. The main conveyor unit 1 drives the multiple pallet assemblies 39 above it to move forward. The worker stands in front of the secondary conveyor unit 2. When the material to be processed moves in front of himself, the hydraulic cylinder 31 is started upward. The hydraulic cylinder 31 drives the mounting seat 32 to move upward. The mounting seat 32 drives the two rotating shafts 33 to move upward. The two rotating shafts 33 drive the two transfer belts 34 to move upward. During the upward movement of the two transfer belts 34, the pallet assembly 39 will be lifted, causing the pallet assembly 39 to lose its connection with the main conveyor unit 1. At this time, the main conveyor unit 1 loses the driving effect on the pallet assembly 39. When the mounting seat 32 moves upward, the mounting seat 32 drives the connecting frame 35 to move upward. The connecting frame 35 drives the gear shaft 37 to move upward. During the upward movement of the gear shaft 37, it rotates through the cooperation with the rack 38. When the gear shaft 37 rotates, it drives one of the rotating shafts 33 to rotate through the two belts 36. The rotating shaft 33 drives the two transfer belts 34 to rotate, so that while the two transfer belts 34 lift the pallet assembly 39 upward, they can also drive the pallet assembly 39 to move leftward through their own rotation. During the leftward movement of the pallet assembly 39, it moves to the receiving seat 310 under the guidance of the guide wheel 312. At this time, the hydraulic cylinder 31 is closed. The hydraulic cylinder 31 drives the mounting seat 32 to move downward. The mounting seat 32 drives the connecting frame 35 to move downward. The connecting frame 35 drives the receiving seat 310 to move downward. The first telescopic rod 311 plays a role in limiting and fixing the receiving seat 310. When the mounting seat 32 returns to its original position, the two transfer belts 34 will not affect the normal operation of the main conveyor unit 1. Since the height of the secondary conveyor unit 2 is lower than that of the main conveyor unit 1, at this time, the pallet assembly 39 on the receiving seat 310 has not contacted the secondary conveyor unit 2 temporarily. At this time, the worker can process the material on the pallet assembly 39;The chassis 391 of the tray assembly 39 plays the role of installation and support. When the chassis 391 contacts the main conveyor unit 1 or the secondary conveyor unit 2, the two contact rods 393 are subjected to the reverse thrust of the main conveyor unit 1 or the secondary conveyor unit 2 and move in the direction of the limit block 394 and contact the limit block 394. When the contact rod 393 contacts the limit block 394, the contact rod 393 will push the limit block 394 upward. After the limit block 394 is pushed upward to the limit groove of the turntable 392, the limit block 394 has a limiting effect on the turntable 392. When the chassis 391 does not contact the main conveyor unit 1 or the secondary conveyor unit 2, the two contact rods 393 will move in the direction of the limit block 394 and contact the limit block 394. When the conveyor group 1 or the secondary conveyor group 2 is in operation, the four contact rods 393 are reset due to the elastic force of the springs, and the limit blocks 394 are reset by their own gravity. At this time, the limit blocks 394 lose their limiting effect on the turntable 392, so that when the chassis 391 is lifted up, the turntable 392 can rotate. When the chassis 391 is being transported, the turntable 392 is limited and cannot rotate. When the staff processes the materials on the turntable 392, they can rotate the materials by rotating the turntable 392, which is convenient for processing the materials. By setting the material transfer device 3, The staff can transfer materials according to their own work rhythm. When the staff is operating, the material transfer device 3 is not started. When the staff has completed the processing of the existing material, the material transfer device 3 is started to transfer the next material. Through the setting of multiple secondary conveyor units 2 and the material transfer device 3, the effect of transferring materials on the main conveyor unit 1 by multiple workstations is achieved, which improves the efficiency of transferring and processing materials. In addition, the staff can adjust the rhythm of material transfer by themselves, which can avoid the situation where some staff members fail to handle the materials in time due to the fixed-speed transportation of the assembly line, thereby affecting the overall work. Through the setting of the tray assembly 39, when the staff is processing the materials, they can rotate the materials by rotating the turntable 392, making the materials easier to process, simplifying the working steps, avoiding the need to adjust their own position due to processing at various angles during processing, thereby affecting work efficiency, and increasing work intensity. When the tray assembly 39 is being transported, the turntable 392 cannot be rotated through the cooperation of the resistance rod 393 and the limit block 394, avoiding the unstable placement of the materials due to the rotation of the turntable 392 during transportation. ;

[0028] The staff members have previously placed various tools and parts required for processing in an orderly manner according to categories and specifications in multiple storage compartments 44 of the tool box 42. During the processing operation by the staff, since the tool box 42 is located beside the tray assembly 39, it is more convenient for the staff to pick up. After the processing operation is completed, the staff activates the hydraulic cylinder 31 downward. The hydraulic cylinder 31 drives the material receiving seat 310 downward through the mounting seat 32 and the connecting frame 35. The material receiving seat 310 drives the tray assembly 39 downward until the chassis 391 contacts the secondary conveying unit 2. When the chassis 391 contacts the secondary conveying unit 2, the secondary conveying unit 2 conveys the tray assembly 39 to the next process. When the material receiving seat 310 moves downward, it drives the fixing member 41 downward, and the fixing member 41 drives the tool box 42 downward. The second telescopic rod 43 plays a role in limiting and fixing the tool box 42. When the tool box 42 moves downward, the tool box 42 drives two cover plates 45 downward, and the two cover plates 45 drive two scissor rods 46 downward. During the downward movement of the two scissor rods 46, due to the extrusion of the sleeve block 47, the upper segments of the two scissor rods 46 move toward each other. During the movement of the two scissor rods 46, they drive the two cover plates 45 to merge. When the two scissor rods 46 move upward, through the extrusion of the sleeve block 47, the two scissor rods 46 drive the two cover plates 45 to open. During the downward movement of the tool box 42, it drives multiple elastic pieces 48 downward. During the downward movement of the multiple elastic pieces 48, they will respectively contact four lever rods 49 and vibrate, causing the multiple elastic pieces 48 to drive the tool box 42 to vibrate. The tool box 42 vibrates to evenly distribute the tools and parts inside the multiple storage compartments 44, facilitating the staff's next pick-up. Through the setting of the auxiliary device 4, it is more convenient for the staff to pick up tools and parts during the processing. Moreover, by placing the parts and tools in the multiple storage compartments 44 according to specifications and categories, the situation of not being able to find tools and parts during work and affecting work efficiency can be reduced, improving the work efficiency of the staff. Through the setting of the two cover plates 45, after the material processing is completed and the tool box 42 descends, the two cover plates 45 automatically merge. The merged cover plates 45 can shield the tools and parts in the tool box 42 to prevent foreign objects from falling into the tool box 42 during transportation. When the next processing operation is carried out and the tool box 42 rises and drives the two cover plates 45 to open, the cover plates 45 can protect the secondary conveying unit 2 below the front and rear sides of the tool box 42, preventing the staff from accidentally dropping small parts into the secondary conveying unit 2 during processing, which may increase the probability of failure of the secondary conveying unit 2. Through the setting of the multiple elastic pieces 48 and the four lever rods 49, during the movement of the tool box 42, the multiple elastic pieces 48 drive the tool box 42 to vibrate. The tool box 42 vibrates to evenly distribute the tools and parts inside the multiple storage compartments 44, facilitating the staff's next pick-up.
