Description

Technical Field

[0001] The invention relates to the technical field of roller conveyors, and in particular to a modular high-speed roller conveyor line and a working method thereof. Background Art

[0002] Modular high-speed roller conveyor is an efficient material transfer system based on modular design concept, which realizes fast and smooth movement of goods through a series of rotating rollers. The biggest feature of this conveyor is its modular design, which allows users to flexibly combine and expand according to actual needs, so as to adapt to different application scenarios.

[0003] The invention patent with publication number CN111517064A discloses a modular sprocket roller conveyor system. In this conveyor system, the motor drives the output gear of the reducer to rotate, which drives the sprocket connected to the output gear of the reducer to rotate, and drives all roller groups to rotate through the transmission connection between adjacent sprockets, completing the operation of the entire roller line. During the operation of this conveyor system, the roller group conveys the conveyor parts, which are generally placed directly on the roller group, or a pallet is set on the roller group, and the conveyor parts are placed on the pallet for conveying. In this conveyor system, although it can play a conveying role on the conveyor parts, it also has the following problems.

[0004] First, since the distance between the roller groups in the system is fixed and inconvenient to adjust, only the conveyor parts within a small range of size can be conveyed; secondly, when the above conveying system is used to convey the conveyor parts, the conveyor parts are easy to slide relative to the roller groups, causing the conveyor parts to slip during the conveying process; finally, when the above conveying system is used to convey the conveyor parts, the stopping accuracy of the conveyor parts is low, and it is difficult to achieve precise position control of the conveyor parts. To this end, we propose a modular high-speed roller conveyor line and its working method. Summary of the invention

[0019] The working method of the modular high-speed roller conveyor line includes the following steps:

[0020] S1. When in use, select a suitable pallet according to the size of the workpiece to be conveyed, start the electric push rod, the electric push rod pushes the slide, the slide pushes the connecting piece through the card seat, the connecting piece pushes the sleeve through the sleeve, the sleeve drives the roller body to move synchronously through the connecting plate and the sliding shaft, and pushes the roller body to a suitable position, and places the pallet on the roller body at both ends of the rotating shaft at the loading end of the frame, the roller body is in the card slot, the card teeth and the external thin layer are engaged in the corresponding tooth slots, and then slide the push plate and the moving frame on the stop plate so that the deceleration assembly on the stop plate is facing the side of the pallet, so that the deceleration assembly on the push plate is located above one side of the deceleration assembly on the stop plate, and rotate the screw so that one of the screws contacts the push plate and the other screw contacts the stop plate, and the position of the deceleration assembly is fixed;

[0021] S2. Use the stand to drive each rotating shaft to rotate, and the rotating shaft drives the pallet to move through the roller body and the latch teeth to transport the object to be transported;

[0022] S3, when the conveying member is transported to the pushing assembly, the lifting assembly drives the first slide, the push plate and the first electric cylinder to descend through the mounting seat, and the push plate is pushed toward the pallet by the first electric cylinder. After the pad on the push plate abuts against the pallet, the first electric cylinder pushes the pallet synchronously;

[0023] S4, after the tray collides with the pad on the stop plate, the movable rod on the compression stop plate shrinks into the sleeve, and the movable rod on the push plate shrinks into the sleeve until the tray collides with the push plate and the stop plate respectively, and the conveying stops.

[0024] The present invention has the following beneficial effects:

[0025] 1. The present invention changes the distance between the roller bodies at both ends of the rotating shaft by adjusting the components, so that pallets of different sizes can be placed on the roller bodies at both ends of the rotating shaft, and pallets within a wide size range can be transported. The conveying parts are placed on the matching pallets, so that different conveying parts can be stably transported.

[0026] 2. The present invention provides latching teeth on the roller body and opens a plurality of tooth grooves matched with the latching teeth on the pallet. During the rotation of the roller body, the latching teeth are screwed into the tooth grooves and meshed with the tooth grooves, which plays an anti-skid role when the roller body transports the pallet, avoiding the slipping problem during the transportation process, preventing the conveying member from deviating from the predetermined conveying position due to the relative sliding between the roller body and the pallet, and avoiding the reduction of the conveying accuracy.

[0027] 3. The present invention can reduce the wear of the latch teeth, the roller body and the tray by arranging a set outside the roller body and the latch teeth. The engagement of the latch teeth and the tooth grooves has a large contact area. By arranging a set for anti-slip on the latch teeth, it also plays a role in preventing the latch teeth from sliding in the tooth grooves during emergency stops.

[0028] 4. The present invention gradually reduces the transmission force of the driving motor on the pallet and gradually increases the transmission force of the pushing assembly on the pallet. When the pallet collides with the stop plate and the push plate respectively, the transmission force of the driving motor on the pallet is reduced to zero, and the pallet is completely colliding with the pushing assembly, so that when the pallet is just in the stop position, the driving motor in the platform will not generate any force on the pallet, thereby avoiding the impact of the conveying action of the driving motor in the platform on the stopping accuracy of the pallet.

[0029] 5. The present invention gradually replaces the conveying effect of the driving motor on the pallet by making the pushing assembly. During the replacement process, the deceleration assembly on the stop plate shrinks more and more obviously, and the reaction force on the pallet gradually increases. Similarly, the deceleration assembly on the pushing assembly shrinks more and more obviously, and the reaction force on the pallet gradually increases, and the moving speed of the pallet becomes slower and slower, so as to gradually reduce the moving speed of the pallet, and finally make the pallet hit the stop plate. At this time, the push plate also just hits the stop plate, and the deceleration assembly on the push plate and the deceleration assembly on the stop plate cancel each other out. The impact of the push plate and the stop plate on the pallet makes the pallet just stay still in the stop position, avoiding the problem of the pallet colliding with the stop plate and the problem of the pallet colliding with the push plate, preventing the collision impact from causing the position of the pallet and the conveying member on the pallet to change, so that the conveying of the conveying member is smoother.

DETAILED DESCRIPTION

[0044] 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. Example

[0045] See also Figure 1 - Fig.11 As shown, a modular high-speed roller conveyor line includes a frame 1, a plurality of rotating shafts 3 evenly spaced and movably arranged inside the frame 1, roller bodies 2 are arranged at both ends of each rotating shaft 3, trays 4 are placed above the roller bodies 2 at both ends of the rotating shaft 3, two card slots 11 are arranged at the bottom of the tray 4, the roller bodies 2 at the ends of the rotating shaft 3 correspond to the card slots 11 one by one, the roller bodies 2 roll on the inner lower side of the corresponding card slots 11, the top wall of each card slot 11 is provided with tooth grooves 10, and the roller bodies 2 is provided with a reinforcing component 9 meshing with the tooth groove 10, the roller body 2 at one end of the rotating shaft 3 is fixedly connected to the rotating shaft 3, the roller body 2 at the other end of the rotating shaft 3 slides on the rotating shaft 3, and the bottom of the platform 1 is provided with an adjusting component 5 for driving the roller body 2 to slide on the rotating shaft 3, and the discharging end of the platform 1 is provided with a pushing component 6 and a positioning component 7, and the outer sides of the pushing component 6 and the positioning component 7 are provided with a deceleration component 8, and the deceleration component 8 reduces the speed of the tray 4 by elastic contraction itself.

[0046] In order to solve the problem that existing conveyor lines are inconvenient to convey conveyed objects within a wider size range, the conveyor line is equipped with pallets 4 of different sizes. By adjusting the component 5 to change the distance between the roller bodies 2 at both ends of the rotating shaft 3, pallets 4 of different sizes can be placed on the roller bodies 2 at both ends of the rotating shaft 3, and pallets 4 within a wider size range can be conveyed. The conveyed objects are placed on the appropriate pallets 4, so that different conveyed objects can be stably conveyed.

[0047] Based on this device, the rotating shaft 3 rotates on the stand 1, and a sprocket is provided at the same end of each rotating shaft 3. The driving motor in the stand 1 drives the sprocket to rotate through a chain to drive the rotating shaft 3 to work.

[0048] The reinforcing component 9 includes a plurality of latch teeth 91 integrally arranged on the outside of the roller body 2, and a sleeve 92 sleeved on the roller body 2 and the outside of the latch teeth 91; during the rotation of the rotating shaft 3, the latch teeth 91 engage with the tooth groove 10 through the sleeve 92, and the roller body 2 is located on the inner side of the slot 11.

[0049] In order to solve the problem that the contact surface between the roller body 2 and the pallet 4 in the existing conveyor line is small, which leads to the problem that relative sliding is likely to occur between the roller body 2 and the pallet 4 when the device is working, in the present design, a latch tooth 91 is provided on the roller body 2, and a plurality of tooth grooves 10 matched with the latch tooth 91 are provided on the pallet 4. During the rotation of the roller body 2, the latch tooth 91 is screwed into the tooth groove 10 and meshed with the tooth groove 10, which plays an anti-skid role when the roller body 2 conveys the pallet 4, avoids slipping during the conveying process, prevents the conveying member from deviating from the predetermined conveying position due to relative sliding between the roller body 2 and the pallet 4, and avoids reduced conveying accuracy.

[0050] By arranging the sleeve 92 outside the roller body 2 and the latching teeth 91, the wear of the latching teeth 91, the roller body 2 and the tray 4 can be reduced. The engagement of the latching teeth 91 and the tooth groove 10 has a large contact area. By arranging the sleeve 92 for anti-slip on the latching teeth 91, it also prevents the latching teeth 91 from sliding on the tooth groove 10 during emergency stop.

[0051] The pushing assembly 6 includes a first electric cylinder 61 arranged above the platform 1, a push plate 62 fixedly arranged at the output end of the first electric cylinder 61, and a lifting assembly 63 for adjusting the height of the first electric cylinder 61 and the push plate 62. The lifting assembly 63 is arranged on the outer side of the platform 1, and a deceleration assembly 8 is movably arranged under the push plate 62; when the conveying member moves to this position, the lifting assembly 63 lowers the height of the first electric cylinder 61 and the push plate 62, and then the first electric cylinder 61 moves by pushing the push plate 62, and the push plate 62 pushes the deceleration assembly 8, so that the deceleration assembly 8 contacts the pallet 4. After the deceleration assembly 8 contacts the pallet 4, the first electric cylinder 61 pushes the deceleration assembly 8 and the pallet 4 to move synchronously.

[0052] The positioning assembly 7 includes a second electric cylinder 71 fixedly arranged above the platform 1, a stop plate 72 fixedly arranged at the output end of the second electric cylinder 71, and a deceleration assembly 8 movably arranged below the stop plate 72. When the stop position of the tray 4 is determined, the second electric cylinder 71 pushes the stop plate 72 to the target position, and the target position of the stop plate 72 satisfies that: when the tray 4 and the stop plate 72 collide, the tray 4 is in the stop position.

[0053] In order to solve the problem of low stopping accuracy and difficulty in achieving accurate position control of the pallet 4 in the existing conveying line during the conveying process, based on this device, when the pallet 4 is about to reach the conveying position, the pushing component 6 is used to convey the pallet 4 to the end. After the pallet 4 contacts the deceleration component 8 on the stop plate 72, the driving motor in the stand 1 reduces the conveying rate of the pallet 4, and the output rate of the first electric cylinder 61 remains unchanged. At this time, the deceleration component 8 on the stop plate 72 itself undergoes elastic contraction, and the deceleration component 8 on the push plate 62 also undergoes elastic contraction, until the pallet 4 respectively conflicts with the stop plate 72 and the push plate 62, and the conveying stops. During this process, the transmission force of the driving motor in the platform 1 on the pallet 4 is gradually reduced, and the transmission force of the pushing component 6 on the pallet 4 is gradually increased. When the pallet 4 respectively collides with the stop plate 72 and the push plate 62, the transmission force of the driving motor in the platform 1 on the pallet 4 is reduced to zero, and the pushing component 6 completely collides with the pallet 4, so that when the pallet 4 is just in the stop position, the driving motor in the platform 1 will not generate any force on the pallet 4, thereby avoiding the impact of the conveying action of the driving motor in the platform 1 on the stopping accuracy of the pallet 4.

[0054] This conveying mode of gradually reducing the transmission force of the driving motor on the tray 4 in the stand 1 and gradually increasing the transmission force of the pushing assembly 6 on the tray 4, after the tray 4 contacts the deceleration assembly 8 on the stop plate 72, the deceleration assembly 8 on the stop plate 72 and the deceleration assembly 8 on the push plate 62 can gradually replace the conveying effect of the driving motor on the tray 4 by elastic contraction. During the replacement process, the deceleration assembly 8 on the stop plate 72 shrinks more and more obviously, and the reaction force on the tray 4 gradually increases. Similarly, the deceleration assembly 8 on the push assembly 6 shrinks more and more obviously, and the reaction force on the tray 4 gradually increases, and the moving speed of the tray 4 becomes slower and slower, which is convenient for gradually reducing the moving speed of the tray 4, and finally causing the tray 4 to contact the stop plate 72. At this time, the push plate 62 also just contacts the stop plate 72, and the deceleration assembly 8 on the push plate 62 and the deceleration assembly 8 on the stop plate 72 offset each other. The contact between the push plate 62 and the stop plate 72 on the tray 4 makes the tray 4 just stop at the stop position. This design avoids the problem of the tray 4 colliding with the stop plate 72 and the problem of the tray 4 colliding with the push plate 62, and prevents the collision impact from causing the position of the tray 4 and the conveying parts on the tray 4 to change, making the conveying of the conveying parts smoother.

[0055] Among them, the kit 92 includes a ring 921 and a plurality of thin layers 922 integrally arranged on the outside of the ring 921. The ring 921 is fixedly sleeved on the outside of the roller body 2. The number of rings 921 and the teeth 91 are the same and correspond one to one. The ring 921 is fixedly arranged on the outside of the corresponding teeth 91. The ring 921 is thicker than the thin layer 922.

[0056] Based on this device, by making the ring 921 and the tray 4 contact each other, the friction between the two is increased, making it difficult for relative sliding to occur between the tray 4 and the roller body 2, and by providing a thin layer 922 on the latch tooth 91, the thin layer 922 is made to contact the inner wall of the tooth groove 10, thereby avoiding wear of the latch tooth 91 and the inner wall of the tooth groove 10, improving the friction between the two, and avoiding relative movement of the latch tooth 91 and the inner wall of the tooth groove 10 due to large starting inertia.

[0057] Among them, a limit bayonet 12 is provided inside each rotating shaft 3, and a sliding shaft 13 and a connecting plate 14 are movably provided inside each limit bayonet 12. Two connecting plates 14 are fixedly provided at each end of the sliding shaft 13. The two connecting plates 14 at one end of the sliding shaft 13 are fixedly connected to the inner wall of the roller body 2 sliding on the rotating shaft 3, and the two connecting plates 14 at the other end of the sliding shaft 13 are fixedly connected with a sleeve 15. The sleeve 15 is movably sleeved on the side of the rotating shaft 3.

A connecting piece 18 is fixedly provided on the outside of each ring 17. The connecting pieces 18 on two adjacent rings 17 are fixedly connected by bolts 19, and the adjustment component 5 pushes each connecting piece 18 to move.

[0058] Based on this device, the adjustment component 5 promotes the movement of the roller body 2 through the design structure, and the rotating shaft 3 drives the roller body 2 to rotate through the sliding shaft 13 and the connecting plate 14. The setting of the sleeve 15, the opening of the annular groove 16 and the setting of the sleeve 17 enable the movement and rotation of the roller body 2 to be carried out independently without being affected.

[0059] Among them, a base 20 is set on one side of the platform 1, and the adjustment component 5 includes an electric push rod 51 fixedly set on the base 20, a slide groove 52 fixedly set on one side of the base 20, a slide 53 movably set above the slide groove 52, and a plurality of clamping seats 54 fixedly set above the slide 53.

[0060] Based on this device, the electric push rod 51 pushes the holder 54 to move through the slide 53, and drives the roller body 2 to move through the corresponding connection structure.

[0061] The pushing assembly 6 further includes a positioning seat 64 disposed outside the platform 1, a mounting seat 65 fixedly disposed above the output end of the lifting assembly 63, and a first slide seat 66 fixedly disposed on one side above the mounting seat 65, wherein one positioning seat 64 is fixedly mounted above one of the bases 20, the first electric cylinder 61 is fixedly mounted above the other side of the mounting seat 65, and the push plate 62 is movably disposed above the first slide seat 66. The lifting assembly 63 is fixedly mounted inside the positioning seat 64.

[0062] Based on this device, the first slide seat 66 limits the push plate 62 , and the push plate 62 slides on the first slide seat 66 .

[0063] A pressure sensor 21 is fixedly disposed at the connection between the output end of the first electric cylinder 61 and the push plate 62 .

[0064] Based on the present device, the pressure sensor 21 is provided to monitor whether the pad 85 is in contact with the tray 4 , and to monitor whether the tray 4 is in contact with the stop plate 72 .

[0065] The positioning assembly 7 further includes a second slide seat 73 fixedly disposed above the platform 1 , and the stop plate 72 is movably disposed above the second slide seat 73 .

[0066] Based on the present device, the second slide seat 73 is arranged so that the stop plate 72 is always in a linear motion state.

[0067] The deceleration assembly 8 includes a sleeve 81, a movable rod 82 movably arranged inside one end of the sleeve 81, a shift shaft 83 and a spring 84 movably arranged inside the sleeve 81, and a pad 85 fixedly arranged at the end of the movable rod 82. One end of the spring 84 abuts against the inner wall of the sleeve 81, and the other end of the spring 84 abuts against one side of the shift shaft 83. The other side of the shift shaft 83 is fixedly connected to one end of the movable rod 82 extending into the sleeve 81. The shift shaft 83 is provided with through holes 22 evenly spaced. The side surface of the shift shaft 83 and the inner wall of the sleeve 81 are fixedly connected with guide shafts 23. The two guide shafts 23 are located inside the spring 84. The provision of the through holes 22 balances the air pressure of the cavities at both ends of the shift shaft 83 in the sleeve 81.

[0068] Based on the present device, after the tray 4 contacts the pad 85 on the stop plate 72, the conveying speed of the driving motor is reduced, and the movable rod 82 on the stop plate 72 is subjected to force to compress the spring 84 and retract into the sleeve 81. Similarly, the movable rod 82 on the push plate 62 is subjected to force to compress the spring 84 and retract into the sleeve 81. The thrust of the movable rod 82 on the stop plate 72 on the tray 4 and the thrust of the movable rod 82 on the push plate 62 on the tray 4 act on the tray 4 respectively, so as to gradually control the movement state of the tray 4 and gradually push the tray 4 to the stop position.
