Description

Technical Field

[0001] This application relates to the technical field of transmission chain assembly, and in particular to an automated transfer device for elevator transmission chain sprockets. Background Technology

[0002] The drive chain is the chain used to transmit motion and power on an escalator. The drive chain is mainly a plate chain, which is assembled from chain plates, bushings, and sprockets. Since the sprockets have two sides, with text printed on the front, during the assembly process, both sprockets on a chain plate need to be facing the front at the same time. Therefore, the sprockets are flipped over during the sprocket transport process to ensure that the front side of the sprocket is facing up when assembled.

[0003] During the assembly of the drive chain, two bushings are first fixed on the lower chain plate, and then two sprockets are respectively fitted onto the two bushings. In order to save assembly time, the two sprockets are usually fitted onto the two bushings at the same time. This requires transferring the flipped sprockets to the two conveyor belts so that the parts can be picked up at the same time when assembling the sprockets.

[0004] Currently, the transfer of sprockets is done manually, which is inefficient; therefore, this application proposes an automated transfer device for elevator drive chain sprockets. Utility Model Content

[0005] To improve the transfer efficiency of the sprocket after flipping, this application provides an automated transfer device for elevator drive chain sprockets.

[0006] This application provides an automated transfer device for elevator drive chain sprockets, which adopts the following technical solution: An automated transfer device for elevator drive chain sprockets includes: The first transfer track is used to receive and transport the sprocket after it has been flipped. The second transfer track is connected to the output end of the first transfer track; The third transfer track is connected to the output end of the first transfer track; the second and third transfer tracks are arranged parallel to each other and at the same height; A transfer component, located at the output end of the first transfer track, is used to transfer the sprocket to the second or third transfer track.

[0007] By adopting the above technical solution, after the sprocket is flipped so that its front side faces up, it enters the first transfer track. When the sprocket passes the output end of the first transfer track, the transfer component works periodically to transfer the sprocket to the feed inlet of the second transfer track or the feed inlet of the third transfer track. The second transfer track and the third transfer track are set in parallel to each other, providing material flow with two sprockets running in parallel for subsequent workstations.

[0008] In summary, by automating the transfer components to transfer the sprockets to the first output rail and the third transfer rail respectively, manual transfer is no longer required, thus improving work efficiency.

[0009] Preferably, the output end of the first transfer track is provided with a transition plate, the transition plate is arranged parallel to the first transfer track, the width of the transition plate is greater than the width of the output end of the first transfer track, the connection between the output end of the first transfer track and the transition plate is located in the middle of the edge of the transition plate, the second transfer track and the third transfer track are connected to the end of the transition plate away from the first transfer track, and the connection between the second transfer track and the third transfer track and the transition plate is located on both sides of the sprocket conveying direction; The transfer assembly includes a cylinder and a pusher block for moving the sprocket. The output shaft of the cylinder is arranged along the width direction of the transition plate. The pusher block is fixed to the end of the output shaft of the cylinder. The pusher block is located at one end of the transition plate near the first transfer track and is suspended above the transition plate.

[0010] By adopting the above technical solution, by widening the transition plate and placing the connection between the first transfer track and the transition plate in the middle of the edge of the transition plate, the sprocket conveyed by the first transfer track can be stably placed in the transfer area of ​​the transition plate. At the same time, space is reserved on both sides for the connection of the two output tracks, solving the spatial adaptation problem of single-input to dual-output turning connection. After the sprocket is output from the first transfer track, it enters the transition plate. The cylinder drives the push block to move along the direction perpendicular to the sprocket conveying. When the push block moves, it pushes the sprocket to one side of the transition plate and enters the second transfer track. When it pushes it to the other side of the transition plate, it enters the third transfer track. The push block is suspended above the transition plate to avoid friction interference with the transition plate and ensure the smoothness of the pushing action.

[0011] Preferably, the input end of the first transfer track is provided with a collecting plate, the collecting plate is arranged parallel to the first transfer track, and the collecting plate is provided with two guide plates, the two guide plates are located on both sides of the sprocket conveying track, and the two guide plates form a figure-eight collecting groove between them; the width of the first transfer track is equal to the diameter of the sprocket, and the first limiting plates are provided on both sides of the first transfer track, the first limiting plates being arranged along the length direction of the first transfer track. The push block has a push groove on one side near the surface of the transition plate. The length direction of the push groove is parallel to the transition plate. The push groove is set along the length direction of the transition plate and passes through the push block. The width of the push groove is equal to the diameter of the sprocket. The width of the transition plate is three times the width of the push groove. There are two push grooves, which are set parallel to each other. One push groove is suspended above the middle of the transition plate, and the other push groove is suspended above one side of the middle of the transition plate.

[0012] By adopting the above technical solution, before the sprocket enters the first transfer track, it first enters the collecting plate. Through the figure-eight-shaped collecting groove formed by the two guide plates and the collecting plate, multiple sprockets are neatly arranged and orderly enter the first transfer track. Since the width of the first transfer track is equal to the diameter of the sprocket, after entering the first transfer track, the sprockets are arranged individually on the first transfer track and can only be output one at a time to the transition plate. After the sprocket enters the transition plate from the outlet end of the first transfer track, the cylinder drives the push block to move along the width direction of the transition plate. The pushing groove above the middle of the transition plate moves with the push block to one side of the transition plate, pushing the groove wall to abut against the sprocket. The moving sprocket moves towards one side of the transition plate; when the push groove with the sprocket moves to one side of the transition plate, another empty push groove moves to the middle of the transition plate; at this time, the sprocket leaves the push groove and enters the first or second conveying track, and the subsequent sprocket enters the empty push groove in the middle of the transition plate; then the cylinder drives the push block to move towards one side of the transition plate, and the groove wall of the push groove in the middle of the transition plate abuts against the sprocket, pushing the sprocket together to move towards the other side of the transition plate. At this time, the push groove that has moved to one side of the transition plate moves back to the middle of the transition plate; this process is repeated, and the sprocket is periodically transferred to the second and third transfer tracks through the two push grooves.

[0013] Preferably, it also includes a sensor for detecting whether the sprocket has reached the transfer position. The sensor is connected to the cylinder signal and is suspended above the sprocket conveying track. The sensor is located on the side of the push block near the first transfer track.

[0014] By adopting the above technical solution, when the sprocket is detected to be in position, the sensor sends an electrical signal to the cylinder, and the cylinder works to drive the push block to move.

[0015] Preferably, a blocking plate is provided on the transition plate. The blocking plate is located at the end of the push block away from the first transfer track, and the blocking plate is located at the end of the push groove away from the first transfer track. The blocking plate is a rectangular plate, and the blocking plate is arranged perpendicular to the transition plate. The blocking plate is arranged along the width direction of the transition plate to block the forward movement of the sprocket. The blocking plate is located in the middle of the width direction of the transition plate.

[0016] By adopting the above technical solution, when the sprocket enters the transition plate from the first transfer track and moves along the conveying direction, the blocking plate will directly block the forward path of the sprocket, providing a fixed point for the pusher groove to push the sprocket and ensuring the transfer accuracy; then the cylinder drives the pusher block to move to one side of the transition plate. At this time, the sprocket rolls along the surface of the blocking plate. Then the sprocket leaves the blocking plate and is no longer blocked by the blocking plate. At this time, the sprocket moves to the feed inlet of the second transfer track or the feed inlet of the third transfer track, and then enters the second transfer track or the third transfer track through transportation.

[0017] Preferably, guide plates are provided on both sides of the blocking plate, and the guide plates are arranged along the conveying direction of the sprocket; there are four guide plates, two of which form a guide plate group, and a guide groove is formed between the two guide plates in a guide plate group. The width of the guide groove is equal to the diameter of the sprocket; the four guide plates form two guide plate groups in total, and the two guide grooves formed by the two guide plate groups are located at both ends of the blocking plate, and the two guide grooves are respectively connected to the feed inlets of the second transfer track and the third transfer track.

[0018] By adopting the above technical solution, two sets of guide plates are set on both sides of the baffle plate to form guide grooves. The two guide grooves are respectively set at the feed inlets of the second transfer track and the third transfer track. After the sprocket is blocked by the baffle plate and pushed by the groove wall, the sprocket rolls along the surface of the baffle plate and rolls into the guide groove. The guide plate then restricts the movement direction of the sprocket to ensure that the sprocket can enter the second transfer track or the third transfer track, preventing the sprocket from tilting or getting stuck when entering the output track, and ensuring the smoothness of the transfer process.

[0019] Preferably, a second limiting plate is provided on both sides of the second transfer track, the second limiting plate is arranged along the length direction of the second transfer track, and the width of the second transfer track is equal to the diameter of the sprocket; a third limiting plate is provided on both sides of the third transfer track, the third limiting plate is arranged along the length direction of the third transfer track, and the width of the third transfer track is equal to the diameter of the sprocket.

[0020] By adopting the above technical solution, after the sprocket enters the second transfer track, the second limiting plate restricts the lateral movement of the sprocket. Since the width of the second transfer track is equal to the diameter of the sprocket, the sprockets enter the second transfer track one by one. Similarly, the second limiting plate also restricts the lateral movement of the sprocket. Since the width of the third transfer track is equal to the diameter of the sprocket, the sprockets enter the third transfer track one by one.

[0021] Preferably, it also includes a frame, the first transfer track is installed obliquely on the frame, and the input end of the first transfer track is higher than the output end; the cylinder bolt is fixed on the frame, and the second transfer track and the third transfer track are both installed on the frame; the sensor is also installed on the frame, and the sensor is located on the side of the push block close to the first transfer track.

[0022] By adopting the above technical solution, the first transfer track is installed at an angle with the input end higher than the output end. The sprocket itself generates a downward component force along the inclined surface, which drives the sprocket to move automatically towards the output end. There is no need to add additional power components such as motors, which reduces energy consumption and ensures the continuity of sprocket conveying.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. After the sprocket is flipped so that its right side is facing up, it enters the first transfer track. As the sprocket passes the output end of the first transfer track, the transfer component works periodically to transfer the sprocket to the inlet of the second transfer track or the inlet of the third transfer track. The second and third transfer tracks are set parallel to each other, providing material flows of two sprockets running in parallel for subsequent workstations. In summary, the transfer component automates the transfer of the sprocket to the first output track and the third transfer track respectively, eliminating the need for manual transfer and improving work efficiency. 2. When the sprocket enters the transition plate from the first transfer track and moves along the conveying direction, the blocking plate will directly block the forward path of the sprocket, providing a fixed point for the push groove to push the sprocket and ensuring transfer accuracy; 3. Two sets of guide plates are set on both sides of the baffle plate to form guide grooves. The two guide grooves are respectively set to the feed inlets of the second transfer track and the third transfer track. After the sprocket is blocked by the baffle plate and pushed by the groove wall, the sprocket rolls along the surface of the baffle plate and rolls into the guide groove. The sprocket's movement direction is then restricted by the guide plate to ensure that the sprocket can enter the second transfer track or the third transfer track. This prevents the sprocket from tilting or getting stuck when entering the output track and ensures the smoothness of the transfer process. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1 - Appendix Figure 2 This application will be described in further detail.

[0027] This application discloses an automated transfer device for elevator drive chain sprockets.

[0028] refer to Figure 1An automated transfer device for elevator drive chain sprockets includes a frame 1, a first transfer track 2, a second transfer track 3, a third transfer track 4, a transfer assembly 5, and a sensor 6. The first transfer track 2 is bolted to the frame 1 and is inclined, with its input end higher than its output end. The second and third transfer tracks 3 and 4 are bolted to the frame 1 and are horizontally arranged and parallel to each other. The inlets of the second and third transfer tracks 3 and 4 are connected to the output end of the first transfer track 2. The transfer assembly 5 is mounted on the frame 1 and is located at the output end of the first transfer track 2 to transfer the sprocket 18 from the output end of the first transfer track 2 to the second and third transfer tracks 3 and 4. The sensor 6 is bolted to the frame 1 to detect whether the sprocket 18 has reached the transfer position, and the sensor 6 is signal-connected to the transfer assembly 5.

[0029] A collecting plate 7 is welded and fixed to the input end of the first transfer track 2. The collecting plate 7 is an isosceles trapezoidal plate and is set parallel to the first transfer track 2. Guide plates 8 are welded and fixed to both sides of the collecting plate 7, and a figure-eight-shaped collecting groove 9 is formed between the two guide plates 8. The width of the first transfer track 2 is equal to the diameter of the sprocket 18, and a first limiting plate 10 is set on both sides of the first transfer track 2. The first limiting plate 10 is set along the length direction of the first transfer track 2. Before the sprocket 18 enters the first transfer track 2, it first enters the collecting plate 7. Through the figure-eight-shaped collecting groove 9 formed by the two guide plates 8 and the collecting plate 7, multiple sprockets 18 are arranged in a regular manner and enter the first transfer track 2 in an orderly manner. The sprockets 18 are arranged individually on the first transfer track 2.

[0030] A transition plate 11 is welded and fixed to the output end of the first transfer track 2. The transition plate 11 is a rectangular plate and is set parallel to the first transfer track 2. The width of the transition plate 11 is three times the diameter of the sprocket 18. The connection between the first transfer track 2 and the transition plate 11 is located at the middle of the width direction of the transition plate 11, so that the position where the sprocket 18 enters the transition plate 11 after being output from the first transfer track 2 is located at the center of the width direction of the transition plate 11.

[0031] The second transfer track 3 and the third transfer track 4 are both connected to the end of the transition plate 11 away from the first transfer track 2. The second transfer track 3 and the third transfer track 4 are on both sides of the middle of the width direction of the transition plate 11. A blocking plate 12 is welded and fixed on the transition plate 11. The blocking plate 12 is a rectangular plate. The blocking plate 12 is set perpendicular to the transition plate 11 and is set along the width direction of the transition plate 11. The blocking plate 12 is located in the middle of the width direction of the transition plate 11 to block the sprocket 18.

[0032] When the sprocket 18 enters the transition plate 11 from the first transfer track 2 and moves along the conveying direction, the blocking plate 12 will directly block the forward path of the sprocket 18, providing a fixed point for the push groove 13 to push the sprocket 18; then the cylinder 51 works to drive the push block 52 to move to one side of the transition plate 11, at which time the sprocket 18 rolls along the surface of the blocking plate 12 to one side of the transition plate 11.

[0033] refer to Figure 1 and Figure 2 The transfer assembly 5 includes a cylinder 51 and a pusher block 52 for moving the sprocket 18. The cylinder 51 is bolted to the frame 1, and the output shaft of the cylinder 51 is arranged along the width direction of the transition plate 11. The pusher block 52 is a cuboid structure. The pusher block 52 is fixed to the end of the output shaft of the cylinder 51 by mounting plate bolts. The pusher block 52 is arranged parallel to the transition plate 11. The pusher block 52 is located at one end of the transition plate 11 near the first transfer track 2 and is suspended above the transition plate 11. The pusher block 52 has a pusher groove 13 with a rectangular cross-section near the surface of the transition plate 11. The length direction of the pusher groove 13 is parallel to the transition plate 11 and the pusher groove 13 is arranged along the length direction of the transition plate 11.

[0034] The width of the push groove 13 is equal to the diameter of the sprocket 18, and the width of the push block 52 is two-thirds of the width of the transition plate 11. There are two push grooves 13, which are arranged parallel to each other. One of the push grooves 13 is suspended in the middle of the transition plate 11. When the sprocket 18 leaves the first transfer track 2 and enters the transition plate 11, the upper part of the sprocket 18 enters the push groove 13 above the middle of the transition plate 11. The other push groove 13 is suspended above one side of the middle of the transition plate 11.

[0035] After the sprocket 18 enters the transition plate 11 from the outlet end of the first transfer track 2, the upper part of the sprocket 18 enters the pushing groove 13 above the middle of the transition plate 11 and is blocked by the blocking plate 12. The cylinder 51 drives the push block 52 to move along the width direction of the transition plate 11. The pushing groove 13 above the middle of the transition plate 11 moves to one side of the transition plate 11 with the push block 52. The groove wall of the pushing groove 13 abuts against the sprocket 18, pushing the sprocket 18 to move towards one side of the transition plate 11. When the pushing groove 13 with the sprocket 18 moves to one side of the transition plate 11, the other empty pushing groove 13 will move to the middle of the transition plate 11. At this time, The sprocket 18 leaves the push groove 13 and enters the first or second conveying track. The subsequent sprocket 18 enters the empty push groove 13 in the middle of the transition plate 11. Then, the cylinder 51 drives the push block 52 to move to one side of the transition plate 11. The groove wall of the push groove 13 in the middle of the transition plate 11 abuts against the sprocket 18, pushing the sprocket 18 together to move to the other side of the transition plate 11. At this time, the push groove 13 that has moved to one side of the transition plate 11 moves to the middle of the transition plate 11 again. This process is repeated, and the sprocket 18 is periodically transferred to the second transfer track 3 and the third transfer track 4 through the two push grooves 13.

[0036] Guide plates 14 are welded and fixed on both sides of the baffle plate 12. The guide plates 14 are arranged along the conveying direction of the sprocket 18. There are four guide plates 14. Two guide plates 14 form a group of guide plates 14. A guide groove 15 is formed between the two guide plates 14 in a group of guide plates 14. The width of the guide groove 15 is equal to the diameter of the sprocket 18. The four guide plates 14 form two groups of guide plates 14. The two guide grooves 15 formed by the two groups of guide plates 14 are located at both ends of the baffle plate 12. The two guide grooves 15 are connected to the feed inlets of the second transfer track 3 and the third transfer track 4, respectively.

[0037] After the sprocket 18 is blocked by the baffle plate 12 and pushed by the wall of the push groove 13, the sprocket 18 rolls along the surface of the baffle plate 12 and then rolls into the guide groove 15. The guide plate 14 then restricts the movement direction of the sprocket 18 to ensure that the sprocket 18 can enter the second transfer track 3 or the third transfer track 4.

[0038] Sensor 6 is a photoelectric sensor 6. Sensor 6 is suspended above the conveying track of sprocket 18. Sensor 6 is bolted to the frame 1. Sensor 6 is located on the side of push block 52 near the first transfer track 2.

[0039] After the sprocket 18 enters the transition plate 11 from the outlet end of the first transfer track 2, the upper part of the sprocket 18 enters the push groove 13 and is blocked by the blocking plate 12. The sensor 6 detects that the sprocket 18 has reached the transfer position and transmits information to the cylinder 51, and the cylinder 51 starts to work.

[0040] The second transfer track 3 is provided with second limiting plates 16 on both sides, the second limiting plates 16 are arranged along the length direction of the second transfer track 3, and the width of the second transfer track 3 is equal to the diameter of the sprocket 18; the third transfer track 4 is provided with third limiting plates 17 on both sides, the third limiting plates 17 are arranged along the length direction of the third transfer track 4, and the width of the third transfer track 4 is equal to the diameter of the sprocket 18.

[0041] Furthermore, a smooth rubber protective pad can be covered on the transport surfaces of the first transfer track 2, the second transfer track 3, and the third transfer track 4 to reduce wear between the sprocket 18 and the track.

[0042] The implementation principle of this application embodiment is as follows: before the sprocket 18 enters the first transfer track 2, it first enters the collection plate 7. Through the figure-eight-shaped collection groove 9 formed by the two guide plates 8 and the collection plate 7, multiple sprockets 18 are neatly arranged and orderly enter the first transfer track 2.

[0043] Since the width of the first transfer track 2 is equal to the diameter of the sprocket 18, after the sprocket 18 enters the first transfer track 2, it is arranged individually on the first transfer track 2 and can only be output to the transition plate 11 one by one. After the sprocket 18 enters the transition plate 11 from the outlet end of the first transfer track 2, the upper part of the sprocket 18 enters the push groove 13 above the middle of the transition plate 11 and is blocked by the blocking plate 12. The sensor 6 detects that the sprocket 18 has reached the transfer position and transmits information to the cylinder 51, and the cylinder 51 starts to work. The working of the cylinder 51 drives the push block 52 to move along the width direction of the transition plate 11. The push groove 13 above the middle of the transition plate 11 moves to one side of the transition plate 11 with the push block 52. The groove wall of the push groove 13 abuts against the sprocket 18 and pushes the sprocket 18 to move towards one side of the transition plate 11.

[0044] When the push groove 13 with sprocket 18 moves to one side of the transition plate 11, another empty push groove 13 moves to the middle of the transition plate 11. At this time, the sprocket 18 leaves the push groove 13 and enters the first or second conveying track, and the subsequent sprocket 18 enters the empty push groove 13 in the middle of the transition plate 11. Then, the cylinder 51 drives the push block 52 to move to one side of the transition plate 11, and the groove wall of the push groove 13 in the middle of the transition plate 11 abuts against the sprocket 18, pushing the sprocket 18 together to move to the other side of the transition plate 11. At this time, the push groove 13 that has moved to one side of the transition plate 11 moves to the middle of the transition plate 11 again. This process is repeated, and the sprocket 18 is periodically transferred to the second transfer track 3 and the third transfer track 4 through the two push grooves 13.

[0045] In summary, this application automates the transfer of sprockets to the first output rail and the third transfer rail using the transfer component 5, eliminating the need for manual transfer and thus improving work efficiency.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
