TECHNICAL FIELD

[0001] The present application relates to a kind of splitting device, especially refers to a kind of automatic lane splitting device. BACKGROUND

[0002] In automatic flow line production, in order to split the parts, the parts conveyed from one side are pushed out from the other side perpendicular to each other. The existing splitting device uses push plate to move back and forth on the plane, and the parts conveyed from one side are pushed out from the other side perpendicular to each other by pushing the parts with the push plate. However, this structure has the problem that after the push plate slides to push the parts out, the push plate needs to return to the starting position to allow the parts to be conveyed into the splitting device, which increases the waiting time and reduces the production efficiency. SUMMARY

[0003] The present application aims to solve the problem of the existing splitting device that after the push plate slides to push the parts out, the push plate needs to return to the starting position to allow the parts to be conveyed into the splitting device, which increases the waiting time and reduces the production efficiency, and provides an automatic lane splitting device that can reduce the processing time and improve the work efficiency.

[0004] The object of the present application can be achieved by the following technical solutions: An automatic lane splitting device includes a rack, a conveying mechanism arranged on the upper end of the rack for conveying parts, a runway motion mechanism arranged below the conveying mechanism, and a pull plate arranged on the runway motion mechanism. The runway motion mechanism drives the pull plate to move in a runway shape, so that the pull plate forms a cyclic motion structure of upward, forward, downward and backward. The cyclic motion structure is: The pull plate first moves upward from the starting point to extend out of the conveying mechanism, then horizontally pushes the parts to move to the side perpendicular to the conveying direction of the conveying mechanism, then moves downward below the conveying mechanism, and then returns to the starting point.

[0005] As a preferred solution, the runway motion mechanism includes first and second guide rods fixedly arranged on the two sides of the rack, first and second guide blocks slidably sleeved on the first and second guide rods, first and second chain transmission mechanisms arranged on the two sides of the rack and moving synchronously, and a lifting mechanism mounted on the first and second guide blocks. The lower end of the lifting mechanism is fixedly connected with the chains of the first and second chain transmission mechanisms, and the upper end of the lifting mechanism is connected with the pull plate. When the chains of the first and second chain transmission mechanisms rotate, the chains drive the lifting mechanism to move in a runway shape.

[0006] As a preferred scheme, the lifting mechanism comprises a connecting rod, a support plate and a slide rod, two ends of the connecting rod are connected with chains of the first chain transmission mechanism and the second chain transmission mechanism respectively, two ends of the support plate are connected with the first guide block and the second guide block respectively, the slide rod is slidably sleeved on the support plate, the lower end of the slide rod is fixedly connected with the connecting rod, and the pull plate is fixedly connected with the upper end of the slide rod.

[0007] As a preferred scheme, the first chain transmission mechanism and the second chain transmission mechanism each comprise a driving sprocket, a driven sprocket and the chain, the chain is in meshing and tension state with the driving sprocket and the driven sprocket, and the driving sprocket is circumscribed by power.

[0008] As a preferred scheme, the conveying mechanism comprises a plurality of rollers which are arranged on the rack and used for conveying the parts to move in the X-axis direction, under the driving of the lifting mechanism, the upper end of the pull plate extends out of or retracts from the gap between adjacent two rollers, and the first chain transmission mechanism and the second chain transmission mechanism drive the pull plate to push the parts to move in the Y-axis direction.

[0009] As a preferred scheme, the first guide block and the second guide block are slidably sleeved on the first guide rod and the second guide rod respectively through first linear bearings.

[0010] As a preferred scheme, the slide rod is slidably sleeved on the support plate through a second linear bearing.

[0011] As a preferred scheme, the rack is provided with a motor, and the motor drives the driving sprocket to rotate.

[0012] As a preferred scheme, the pull plate is uniformly provided with grooves, and a pushing part is formed between two adjacent grooves, when the pull plate is raised upward, the rollers are rotatably sleeved in the grooves, the pushing part extends into the gap between adjacent two rollers, and the upper end of the pushing part extends out of the gap between adjacent two rollers.

[0013] The present application has the following beneficial effects: 1. Compared to the traditional pusher plate operation of a sorting device: After a part is conveyed onto the conveying mechanism, the pusher plate pushes the part from the starting point to a side perpendicular to the conveying direction, causing the part to be pushed off the conveying mechanism. Then, the pusher plate returns horizontally to the starting point. During the return process, the conveying mechanism needs to pause conveying parts and can only restart conveying parts after the pusher plate returns to the starting point. In this invention, after the pusher plate pushes the part off the side perpendicular to the conveying direction, the pusher plate is driven by the track motion mechanism to move downwards to below the conveying mechanism and return to the starting point. Throughout the return process, the pusher plate does not interfere with the parts on the conveying mechanism. Therefore, the conveying mechanism can continuously convey parts without interruption, reducing processing time and improving work efficiency.

[0014] 2. In this invention, after the pulling plate pushes a batch of parts off the conveying mechanism from a side perpendicular to the conveying direction, a new batch of parts is conveyed to the position of the pulling plate as the pulling plate descends below the conveying mechanism and returns to its starting point. At this time, the track motion mechanism drives the pulling plate to extend upwards out of the conveying mechanism and pushes the new batch of parts to a side perpendicular to the conveying direction, thus pushing the parts off. Throughout the entire process, the conveying mechanism, the track motion mechanism, and the pulling plate are all in continuous operation without any standby, saving working time and greatly improving overall work efficiency.

[0015] 3. When the chains of the first chain drive mechanism and the second chain drive mechanism rotate, the lifting mechanism, limited by the first guide block and the first guide rod, as well as the second guide block and the second guide rod, can only move in a track-shaped motion on the vertical plane under the drive of the track motion mechanism. This allows the lifting mechanism to form an upward-forward-downward-backward cyclic motion structure, ultimately enabling the pull plate to perform an upward-forward-downward-backward cyclic motion structure. This eliminates the need for temporary machine stops during the entire workflow, saving time and improving work efficiency. Attached Figure Description

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described in combination with the drawings of the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application. EMBODIMENT

[0023] With reference to Figure 1 and Figure 2 , the present embodiment relates to an automatic lane-changing and separating device, which comprises a rack 1, a conveying mechanism 2 arranged at the upper end of the rack 1 and used for conveying parts, a runway movement mechanism 3 arranged below the conveying mechanism 2, and a separating plate 4 arranged on the runway movement mechanism 3; the runway movement mechanism 3 drives the separating plate 4 to move in a runway shape, so that the separating plate 4 forms a cyclic movement structure of upward-forward-downward-backward; the cyclic movement structure is as follows: The separating plate 4 first moves upward from a starting point, so that the upper end of the separating plate 4 extends out of the conveying mechanism 2, then the separating plate 4 horizontally pushes the parts to move to one side perpendicular to the conveying direction of the conveying mechanism 2, so that the parts are pushed off the conveying mechanism 2, then the separating plate 4 moves downward again, so that the upper end of the separating plate 4 descends below the conveying mechanism 2, and finally the separating plate 4 returns to the starting point, thereby realizing the cyclic movement of the separating plate 4 in the vertical plane of upward-forward-downward-backward under the driving of the runway movement mechanism 3. Compared with the conventional separating plate whose starting point is located at one side in the horizontal direction of the conveying mechanism, the starting point of the separating plate of the present application is located below the conveying mechanism, so that the conveying mechanism 2 can convey the parts forward together in the working state in the process that the separating plate rises upward to the position that the upper end of the separating plate extends out of the conveying mechanism, and the conveying mechanism can also convey the parts forward together in the working state in the process that the separating plate descends to below the conveying mechanism to return to the starting point, without stopping the conveying of the parts to wait for the separating plate to return to the starting point, thereby greatly saving time and improving the work efficiency.

[0024] ​​The working process of the push plate of the present application relative to the traditional separating device is as follows: after the parts are conveyed onto the conveying mechanism 2, the push plate pushes the parts from the starting point to the side perpendicular to the conveying direction of the conveying mechanism 2, so that the parts are pushed off the conveying mechanism 2, and then the push plate 4 returns horizontally to the starting point. During the returning process of the push plate 4 to the starting point, the conveying mechanism 2 needs to pause the conveying of the parts, and the conveying mechanism 2 needs to be restarted to convey the parts after the push plate 4 returns to the starting point. However, in the present application, after the push plate 4 pushes the parts from the side perpendicular to the conveying direction of the conveying mechanism 2, the push plate 4 is driven by the runway movement mechanism 3 to move downward below the conveying mechanism 2 and return to the starting point. During the entire returning process, the push plate 4 does not interfere with the parts on the conveying mechanism 2, so the conveying mechanism 2 can continuously convey the parts without pausing, thereby reducing the processing time and improving the working efficiency.

[0025] As shown in Figure 1 the structure, after a batch of parts on the conveying mechanism 2 are pushed off the side perpendicular to the conveying direction of the conveying mechanism 2, a new batch of parts is conveyed by the conveying mechanism 2 to the position of the push plate 4 during the process of the push plate 4 descending below the conveying mechanism 2 to return to the starting point. At this time, the runway movement mechanism 3 drives the push plate 4 to extend upward above the conveying mechanism 2 and push the new batch of parts to move to the side perpendicular to the conveying direction of the conveying mechanism 2 and push the parts off. During the entire process, the conveying mechanism 2, the runway movement mechanism 3, and the push plate 4 are all in working state without standby, thereby saving the working time and greatly improving the working efficiency.

[0026] The runway movement mechanism 3 includes first guide rods 31 and second guide rods 32 fixedly arranged on the two sides of the rack 1, first guide blocks 33 and second guide blocks 34 slidably sleeved on the first guide rods 31 and the second guide rods 32, first chain transmission mechanisms 35 and second chain transmission mechanisms 36 arranged on the two sides of the rack 1, and lifting mechanisms 37 installed on the first guide blocks 33 and the second guide blocks 34. The lower ends of the lifting mechanisms 37 are fixedly connected with the chains of the first chain transmission mechanisms 35 and the second chain transmission mechanisms 36, and the upper ends of the lifting mechanisms 37 are connected with the push plate 4. When the chains of the first chain transmission mechanisms 35 and the second chain transmission mechanisms 36 rotate, the lifting mechanisms 37 are limited by the first guide blocks 33, the first guide rods 31, the second guide blocks 34, and the second guide rods 32, and can only move in a runway shape in the vertical plane under the drive of the runway movement mechanism 3, so as to form a cyclic movement structure of upward-forward-downward-backward, and finally make the push plate 4 move in a cyclic movement structure of upward-forward-downward-backward, so that the entire working process does not need to be temporarily stopped, time is saved, and the working efficiency is improved.

[0027] The lifting mechanism 37 includes a connecting rod 371, a support plate 372, and a sliding rod 373. The two ends of the connecting rod 371 are respectively connected to the chains 363 of the first chain transmission mechanism 35 and the second chain transmission mechanism 36. The two ends of the support plate 372 are respectively connected to the first guide block 33 and the second guide block 34. The sliding rod 373 is slidably sleeved on the support plate 372. The lower end of the sliding rod 373 is fixedly connected to the connecting rod 371. The pull plate 4 is fixedly connected to the upper end of the sliding rod 373. When the first chain drive mechanism 35 and the second chain drive mechanism 36 work synchronously, the chain 363 of the first chain drive mechanism 35 and the second chain drive mechanism 36 drives the connecting rod 371 to move in a racetrack shape. However, due to the limiting effect of the support plate 372, the guide block and the guide rod, the slide rod 373, which is fixedly connected to the connecting rod 371 at its lower end, can only move in a racetrack shape in the vertical plane, thereby driving the pull plate 4 to move in an upward-forward-downward-backward cycle.

[0028] Both the first chain drive mechanism 35 and the second chain drive mechanism 36 include a driving sprocket 361, a driven sprocket 362, and a chain 363. The chain 363 meshes with the driving sprocket 361 and the driven sprocket 362 and is in a tensioned state. The driving sprocket 361 is externally powered. The driving sprocket 361 drives the chain 363 and the driven sprocket 362 to rotate. When the first chain drive mechanism 35 and the second chain drive mechanism 36 are working, the two chains 363 rotate synchronously, so that the two ends of the connecting rod 371 can move synchronously, ensuring that the connecting rod 371 can smoothly drive the slide rod 373 to move in a racetrack shape.

[0029] The conveying mechanism 2 includes multiple rollers 21 spaced apart on the frame 1 for conveying parts moving in the X-axis direction. Driven by the lifting mechanism 37, the upper end of the pull plate 4 extends out of the gap between two adjacent rollers 21 or retracts from the gap between two adjacent rollers 21. The first chain drive mechanism 35 and the second chain drive mechanism 36 drive the pull plate 4 to push the parts moving in the Y-axis direction. Figure 1 As shown, the X-axis direction is the direction in which the rollers 21 of the conveying mechanism 2 drive the parts to move, while the Y-axis direction is the direction in which the pull plate 4 pushes the parts to a side perpendicular to the conveying direction of the conveying mechanism 2. Driven by the lifting mechanism 37, the upper end of the pull plate 4 first extends out of the gap between two adjacent rollers 21, then pushes the parts to move in the Y-axis direction, and then the pull plate 4 moves downward, causing the upper end of the pull plate 4 to descend below the rollers 21. Then the pull plate 4 moves along the Y-axis direction and returns to the starting point. Then the upper end of the pull plate 4 extends out of the gap between two adjacent rollers 21 again, forming a continuous upward-forward-downward-backward cyclic motion structure.

[0030] In order to reduce the frictional force when the first guide block 33 and the second guide block 34 slide and improve the smoothness of the sliding of the first guide block 33 and the second guide block 34, the first guide block 33 and the second guide block 34 are respectively slidably sleeved on the first guide rod 31 and the second guide rod 32 through the first linear bearing 37.

[0031] In order to reduce the friction of the slide bar 373 during sliding and improve the smoothness of the slide bar 373, the slide bar 373 is slidably sleeved on the support plate 372 through the second linear bearing.

[0032] A motor 10 is mounted on the frame 1, which drives the drive sprocket 361 to rotate. The two drive sprockets 361 are fixedly connected together by a fixing rod 11. After the motor 10 is connected to one of the drive sprockets 361, it can achieve the purpose of synchronously driving the two drive sprockets 361 to work synchronously, thereby ensuring that the two drive sprockets 361 can drive the two chains 363 to rotate synchronously. Example

[0033] This embodiment is an improvement on the structure of the pull-out plate 4 based on embodiment 1, such as... Figure 1 , Figures 3 to 5 As shown, the pull plate 4 has evenly spaced grooves 41, and a pushing part 42 is formed between two adjacent grooves 41. When the pull plate 4 rises, the roller 21 can be rotatably fitted into the groove, and the pushing part 42 extends into the gap between two adjacent rollers 21, with the upper end of the pushing part 42 extending out of the gap between the two adjacent rollers 21. This structure uses a single pull plate 4 to synchronously push parts at different positions in the X-axis direction; during installation, only one pull plate 4 needs to be installed, which is relatively... Figure 1 The previous structure required multiple pull plates 4 to be installed one by one. This structure uses a single thin plate with grooves evenly cut on the pull plate, and a pushing part formed between two adjacent grooves. When the pull plate rises, the roller can be rotated and fitted into the groove. The pushing part is inserted into the gap between two adjacent rollers, and the upper end of the pushing part extends out of the gap between two adjacent rollers. This structure greatly reduces the number of processing steps and processes, and makes installation more convenient and faster.

[0034] The above description is merely a preferred embodiment of the present invention and should not be construed as limiting the scope of the invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
