Description

Technical Field

[0001] This invention relates to an elastic band collecting device and a collecting method, belonging to the field of elastic band collecting devices. Background Technology

[0002] Elastic bands, also known as elastic threads or rubber bands, are a type of strip-shaped fabric made by combining elastic materials with textile fibers. They are mainly used as clothing accessories.

[0003] When pre-cut elastic bands are being wound up, even with stable tension, edge curling and localized bulges can still occur due to the material and thickness of the elastic band. To prevent edge curling and localized bulges from affecting the flatness of the wound material during winding, a smoothing structure is installed on the elastic band winding equipment. This smoothing structure is usually a single-point or single-sided contact. When the elastic band is wound to a thicker state, insufficient smoothing pressure or a too small smoothing area can affect the smoothing effect. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide an elastic band take-up device and method to solve the problem that, even when tension is kept stable during the take-up of sheet elastic bands awaiting cutting, curling edges and local bulges still occur due to the material and thickness of the elastic band. To prevent curling edges and local bulges from affecting the flatness of the take-up during the winding process, a smoothing structure is installed on the elastic band take-up device. This smoothing structure is generally a single-point or single-sided contact. When the elastic band is wound to a thicker state, insufficient smoothing pressure or a too small smoothing area can affect the smoothing effect.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: an elastic band take-up device, the structure of which includes a base, a take-up unit, and a flip-type smoothing unit; the take-up unit is provided in two and is symmetrically rotated on the left and right sides of the upper end face of the base; the flip-type smoothing unit is located at the center of the upper end face of the base to squeeze and smooth the elastic band wound on one of the take-up units.

[0006] The flipping material-guiding unit includes a column vertically fixed to the base, a fixed seat, a flipping component, a material-guiding component, a monitoring component, and a controller. The fixed seat is fixedly connected to the middle section of the front end of the column. The flipping component is horizontally connected to the bottom surface of the fixed seat. The material-guiding component is located on the flipping component at the end away from the fixed seat. The monitoring component is connected to the front end of the flipping component to monitor the position of the elastic band wound on the receiving unit. The controller is used to receive signals from the monitoring component and control the operation of the flipping component and the material-guiding component. The flipping component drives the material-guiding component to flip.

[0007] The material handling assembly includes a horizontally arranged first drive cylinder, a fixed plate, and a telescopic material handling plate. The output end of the first drive cylinder faces one of the receiving units. The output end of the first drive cylinder is fixedly connected to the center of the vertically arranged fixed plate. The telescopic material handling plate is located on the end face of the fixed plate away from the first drive cylinder.

[0008] The telescopic smoothing plate has a smoothing piece embedded in the center of its end face away from the fixed plate, which contacts the elastic band wound on the receiving unit. The telescopic smoothing plate has an L-shaped telescopic channel, and an arc-shaped elastic pressure plate is movably installed in the L-shaped telescopic channel. The short side of the L-shaped telescopic channel protrudes through the rear edge of the telescopic smoothing plate to form an opening. One end of the arc-shaped elastic pressure plate extends out from the opening of the L-shaped telescopic channel and has a smoothing roller vertically installed. The smoothing roller contacts the elastic band wound on the receiving unit. The front of the telescopic smoothing plate has a second drive cylinder that drives the arc-shaped elastic pressure plate to move horizontally backward.

[0009] Furthermore, in order to perform a flipping operation to switch to smoothing work on the unloaded receiving unit, the flipping assembly includes a positioning plate fixedly connected to the fixed base, a flipping shaft, a flipping frame, and a flipping motor. The flipping shaft rotates longitudinally through the positioning plate. The flipping frame is horizontally arranged. One end of the flipping frame is fixedly connected to the first drive cylinder, and the other end is fixedly connected to the front end of the flipping shaft. The flipping motor is located on the rear end face of the positioning plate, and the output end of the flipping motor is connected to the rear end of the flipping shaft to drive the flipping frame to rotate through the flipping shaft. The middle section of the front end face of the flipping frame is provided with an assembly hole for connecting a monitoring component.

[0010] Furthermore, in order to accurately monitor the diameter change of the elastic band, the monitoring component includes a monitoring rod that is horizontally and longitudinally fixed to the middle section of the front end face of the flipping frame, and a sensor located on the outer wall of the monitoring rod, with the monitoring end of the sensor facing the receiving unit.

[0011] Furthermore, for ease of assembly and disassembly, the receiving unit includes a receiving cylinder that is vertically rotatably mounted on the upper surface of the base, a first limiting plate located at the upper end of the receiving cylinder, and a second limiting plate located at the lower end of the receiving cylinder. The second limiting plate has a connecting slot at the center of its bottom surface. A driving block that rotatably engages with the connecting slot is mounted on the base. A main shaft motor that drives the driving block to rotate is located inside the bottom of the base. An electric clamping assembly is mounted on the receiving cylinder to clamp and fix the elastic band.

[0012] Furthermore, in order to improve the connection and fixing efficiency of the elastic band, the electric clamping assembly includes a drive bar located on the inner wall of one side of the take-up cylinder. The drive bar is vertically provided with a clamping slot that protrudes from the outer wall of the take-up cylinder. A clamping plate is movably provided on the inner wall of one side of the clamping slot. An electric push rod is provided inside the drive bar to drive the clamping plate to move horizontally back and forth.

[0013] Furthermore, to improve the clamping firmness, the end face of the clamping plate away from the electric actuator is provided with a number of pressure pins from top to bottom.

[0014] Furthermore, in order to position the extension and retraction of the arc-shaped elastic pressure plate, the opening of the L-shaped telescopic channel is provided with an arc-shaped positioning surface that fits against the outer wall of the arc-shaped elastic pressure plate, so as to position the extension of the arc-shaped elastic pressure plate.

[0015] A material collection method for an elastic band collection device, derived from the operation of the elastic band collection device, includes the following steps:

[0016] Step S1: Set the elastic band receiving device at the outlet of the elastic band processing equipment. After the elastic band to be cut is exported, it is connected to the receiving tube of one of the receiving units. The elastic band is inserted into the clamping slot. After the electric push rod drives the clamping plate to clamp and position the elastic band, the receiving work can be carried out.

[0017] In step S2, under the control of the controller, the main spindle motor drives the second limit plate to rotate through the drive block, and the take-up cylinder on the second limit plate rotates accordingly to wind up the elastic band.

[0018] Step S3: During the winding process of the elastic band, the monitoring component monitors the diameter of the elastic band in real time and sends the signal to the controller. After the controller calculates, it controls the first drive cylinder to drive the smoothing component to move towards the elastic band. After the smoothing component contacts the elastic band, it performs the smoothing work. Under the drive of the first drive cylinder, the smoothing component will change position according to the change of the diameter of the elastic band.

[0019] In step S4, the smoothing sheet and smoothing roller in the smoothing assembly come into contact with the elastic band to perform preliminary smoothing. When the monitoring assembly detects that the winding thickness of the elastic band reaches 10-15cm, the controller controls the second drive cylinder to operate. The second drive cylinder drives the arc-shaped elastic pressure plate to extend through the opening of the L-shaped telescopic channel. During this process, the smoothing roller on the arc-shaped elastic pressure plate is still in contact with the elastic band. Under the positioning of the arc-shaped elastic pressure plate and the opening of the L-shaped telescopic channel, the arc-shaped elastic pressure plate unfolds. Due to the elasticity of the arc-shaped elastic pressure plate, the smoothing roller will be subjected to the elastic force of the arc-shaped elastic pressure plate, thereby strengthening the compression of the elastic band to prevent the thicker elastic band from still being uneven after preliminary smoothing.

[0020] In step S5, after the receiving unit in step S4 is fully loaded, the elastic band is cut manually or by machine. Then, the elastic band is attached to another receiving unit. The controller controls the operation of the flipping component, and the flipping motor drives the flipping shaft to rotate. The flipping shaft drives the flipping frame to rotate 180 degrees clockwise or counterclockwise. The flipping frame drives the smoothing component to turn towards another receiving unit. The receiving and smoothing work in step S4 can be repeated. Meanwhile, the workers disassemble and move the fully loaded receiving unit. Finally, the unloaded receiving unit is assembled to the base. The receiving work is carried out alternately until the elastic band is completely received.

[0021] The beneficial effects of this invention are:

[0022] The elastic band taking-up equipment with dual winding stations can quickly connect and take-up, effectively improving the efficiency of taking up large quantities of elastic bands.

[0023] The elastic band taking-up equipment is equipped with a flipping smoothing unit. By flipping, the elastic bands wound on the two taking-up units are smoothed in sequence. There is no need to set up two corresponding smoothing structures, which optimizes the layout of the overall structure and improves the compactness of the overall structure.

[0024] The flip-type smoothing unit is equipped with a double-point contact smoothing component with telescopic function. The smoothing range and smoothing pressure are adjusted according to the change of the winding diameter of the elastic band, which effectively improves the smoothing effect.

[0037] like Figure 2As shown, the flipping material handling unit 3 includes a column 31 vertically fixed to the base 1, a fixed seat 32, a flipping component 33, a material handling component 34, a monitoring component 35, and a controller 36.

The material handling component 34 is located on the flipping component 33 at the end away from the fixed seat 32. The monitoring component 35 is connected to the front end of the flipping component 33 to monitor the position of the elastic band wound on the receiving unit 2. The controller 36 is used to receive signals from the monitoring component 35 and control the operation of the flipping component 33 and the material handling component 34. The flipping component 33 drives the material handling component 34 to flip. The fixed seat 32 is fixed to the column 31 with bolts, and the fixed seat 32 plays a supporting and positioning role.

[0038] The material handling assembly 34 includes a horizontally arranged first drive cylinder 341, a fixed plate 342, and a telescopic material handling plate 343. The output end of the first drive cylinder 341 faces one of the receiving units 2. The output end of the first drive cylinder 341 is fixedly connected to the center of the vertically arranged fixed plate 342. The telescopic material handling plate 343 is located on the end face of the fixed plate 342 away from the first drive cylinder 341.

[0039] Among them, such as Figure 3 , 4 As shown in Figure 5, a smoothing piece 3431 is embedded in the center of the end face of the telescopic smoothing plate 343 away from the fixed plate 342, which contacts the elastic band wound on the receiving unit 2. The telescopic smoothing plate 343 is provided with an L-shaped telescopic channel 3432, and an arc-shaped elastic pressure plate 3433 is movably arranged in the L-shaped telescopic channel 3432. The short side of the L-shaped telescopic channel 3432 protrudes through the rear edge of the telescopic smoothing plate 343 to form an opening. One end of the arc-shaped elastic pressure plate 3433 extends out from the opening of the L-shaped telescopic channel 3432 and is vertically provided with a smoothing roller 3434. The smoothing roller 3434 contacts the elastic band wound on the receiving unit 2. The front part of the telescopic smoothing plate 343 is provided with a second drive cylinder 3435 that drives the arc-shaped elastic pressure plate 3433 to move backward in the horizontal axis. The first drive cylinder 341 and the second drive cylinder 3435 are electric cylinders to improve the driving accuracy.

[0040] Among them, the smoothing sheet 3431 and the smoothing roller 3434 are both made of stainless steel. The outer walls of the smoothing sheet 3431 and the smoothing roller 3434 are smooth to prevent wear on the surface of the elastic band. The arc-shaped elastic pressure plate 3433 is made of carbon fiber, which has the advantages of elasticity, light weight and high strength, excellent rigidity, high stability and high durability.

[0041] The arc-shaped elastic pressure plate 3433 and the smoothing roller 3434 are rotatably connected, and the arc-shaped elastic pressure plate 3433 is provided with a bearing for positioning the middle section of the smoothing roller 3434.

[0042] In order to perform a flipping operation to switch to smoothing work on the unloaded receiving unit 2, the flipping assembly 33 includes a positioning plate 331 fixedly connected to the fixed base 32, a flipping shaft 332, a flipping frame 333, and a flipping motor 334. The flipping shaft 332 rotates longitudinally through the positioning plate 331. The flipping frame 333 is horizontally arranged. One end of the flipping frame 333 is fixedly connected to the first drive cylinder 341, and the other end is fixedly connected to the front end of the flipping shaft 332. The flipping motor 334 is located on the rear end face of the positioning plate 331. The output end of the flipping motor 334 is connected to the rear end of the flipping shaft 332 to drive the flipping frame 333 to rotate through the flipping shaft 332. The middle section of the front end face of the flipping frame 333 is provided with an assembly hole for connecting the monitoring assembly 35.

[0043] In order to accurately monitor the diameter change of the elastic band, the monitoring component 35 includes a monitoring rod 351 that is horizontally and longitudinally fixed to the middle section of the front end face of the flipping frame 333, and a sensor 352 disposed on the outer wall of the monitoring rod 351, with the monitoring end of the sensor 352 facing the receiving unit 2.

[0044] Among them, sensor 352 is a distance sensor, which determines the winding diameter of the elastic band by monitoring the distance to the elastic band.

[0045] like Figure 5 As shown, for easy assembly and disassembly, the receiving unit 2 includes a receiving cylinder 21 vertically rotatably mounted on the upper surface of the base 1, a first limiting plate 22 mounted on the upper end of the receiving cylinder 21, and a second limiting plate 23 mounted on the lower end of the receiving cylinder 21. The second limiting plate 23 has a connecting slot 24 at the center of its bottom surface. The base 1 is rotatably mounted with a driving block 11 that engages with the connecting slot 24. The bottom of the base 1 is equipped with a main shaft motor 12 that drives the driving block 11 to rotate. The receiving cylinder 21 is equipped with an electric clamping assembly 25 to clamp and fix the elastic band.

[0046] The shape of the drive block 11 perfectly matches the connecting slot 24. The top view cross section of the drive block 11 is one of the following: straight, cross, or star-shaped. However, the present invention is not limited to this. The top view cross section of the drive block 11 can also be polygonal, as long as it can drive the second limiting disk 23 to rotate under the drive of the main spindle motor 12 after being connected to the connecting slot 24.

[0047] like Figure 6As shown, in order to improve the connection and fixing efficiency of the elastic band, the electric clamping assembly 25 includes a drive bar 251 located on the inner wall of one side of the take-up cylinder 21. The drive bar 251 is vertically provided with a clamping slot 252 that protrudes from the outer wall of the take-up cylinder 21. A clamping plate 253 is movably provided on the inner wall of one side of the clamping slot 252. An electric push rod 254 is provided in the drive bar 251 to drive the clamping plate 253 to move horizontally back and forth.

[0048] In order to position the extension and retraction of the arc-shaped elastic pressure plate 3433, the opening of the L-shaped telescopic channel 3432 is provided with an arc-shaped positioning surface that fits against the outer wall of the arc-shaped elastic pressure plate 3433, so as to position the extension of the arc-shaped elastic pressure plate 3433.

[0049] A material collection method for an elastic band collection device, derived from the operation of the elastic band collection device, includes the following steps:

[0050] Step S1: Set the elastic band receiving device at the outlet of the elastic band processing equipment. After the elastic band to be cut is exported, it is connected to the receiving cylinder 21 of one of the receiving units 2. The elastic band is inserted into the clamping slot 252. After the electric push rod 254 drives the clamping plate 253 to clamp and position the elastic band, the receiving work can be carried out.

[0051] In step S2, under the control of the controller 36, the main spindle motor 12 drives the second limit disk 23 to rotate through the drive block 11, and the take-up cylinder 21 on the second limit disk 23 rotates accordingly to wind up the elastic band.

[0052] In step S3, during the winding process of the elastic band, the sensor 352 monitors the diameter of the elastic band in real time and sends the signal to the controller 36. After calculation, the controller 36 controls the first drive cylinder 341 to drive the smoothing component 34 to move towards the elastic band. After the smoothing component 34 contacts the elastic band, it performs a smoothing operation. Under the drive of the first drive cylinder 341, the smoothing component 34 will change its position according to the change in the diameter of the elastic band.

[0053] In step S4, the smoothing sheet 3431 and smoothing roller 3434 in the smoothing assembly 34 come into contact with the elastic band to perform preliminary smoothing. When the sensor 352 detects that the winding thickness of the elastic band reaches 10-15cm, if... Figure 3 , 4As shown, the controller 36 controls the second drive cylinder 3435 to operate. The second drive cylinder 3435 drives the arc-shaped elastic pressure plate 3433 to extend through the opening of the L-shaped telescopic channel 3432. During this process, the smoothing roller 3434 on the arc-shaped elastic pressure plate 3433 is still in contact with the elastic band. Under the positioning of the L-shaped telescopic channel 3432 and the smoothing roller 3434, the arc-shaped elastic pressure plate 3433 unfolds. Due to the elasticity of the arc-shaped elastic pressure plate 3433, the smoothing roller 3434 will be subjected to the elastic force of the arc-shaped elastic pressure plate 3433, thereby strengthening the compression of the elastic band to prevent the thicker elastic band tube from still being uneven after initial smoothing.

[0054] In step S5, after the receiving unit 2 in step S4 is fully loaded, the elastic band is cut manually or by machine. Then, the elastic band is attached to another receiving unit 2. The controller 36 controls the operation of the flipping component 33, and the flipping motor 334 drives the flipping shaft 332 to rotate. The flipping shaft 332 drives the flipping frame 333 to rotate 180 degrees clockwise or counterclockwise. The flipping frame 333 drives the smoothing component 34 to turn towards another receiving unit 2. The receiving and smoothing work in step S4 can be repeated. Meanwhile, the workers disassemble and transport the fully loaded receiving unit 2. Finally, the unloaded receiving unit 2 is assembled to the base 1. The receiving work is carried out alternately until the elastic band is completely received. Example 2

Figure 8 As shown, in order to improve the clamping firmness, the end face of the clamping plate 253 away from the electric push rod 254 is provided with a number of pressure pins 255 from top to bottom. The setting of the pressure pins 255 is mainly used for elastic bands that are hard and difficult to clamp.

The elastic band collecting device according to claim 1, characterized in that: The opening of the L-shaped telescopic channel (3432) is provided with an arc-shaped positioning surface that fits the outer wall of the arc-shaped elastic pressure plate (3433) to position the extension of the arc-shaped elastic pressure plate (3433).

8. A method for collecting elastic bands using a collecting device, characterized in that: Based on the operation of the elastic band take-up device according to claim 6, the take-up method includes the following steps: Step S1: Set the elastic band receiving device at the outlet of the elastic band processing equipment. After the elastic band to be cut is exported, it is connected to the receiving cylinder (21) of one of the receiving units (2). The elastic band is inserted into the clamping slot (252). After the electric push rod (254) drives the clamping plate (253) to clamp and position the elastic band, the receiving work can be carried out. In step S2, under the control of the controller (36), the main spindle motor (12) drives the second limit plate (23) to rotate through the drive block (11), and the take-up cylinder (21) on the second limit plate (23) rotates accordingly to wind up the elastic band. In step S3, during the winding process of the elastic band, the monitoring component (35) monitors the diameter of the elastic band in real time and sends the signal to the controller (36). After the controller (36) performs the calculation, it controls the first drive cylinder (341) to drive the smoothing component (34) to move towards the elastic band. After the smoothing component (34) contacts the elastic band, it performs the smoothing work. Under the drive of the first drive cylinder (341), the smoothing component (34) will change its position according to the change in the diameter of the elastic band. In step S4, the smoothing sheet (3431) and smoothing roller (3434) in the smoothing assembly (34) come into contact with the elastic band to perform preliminary smoothing. When the monitoring assembly (35) detects that the winding thickness of the elastic band reaches 10-15cm, the controller (36) controls the second drive cylinder (3435) to operate. The second drive cylinder (3435) drives the arc-shaped elastic pressure plate (3433) to extend through the opening of the L-shaped telescopic channel (3432). During this process, the arc-shaped elastic pressure plate (3433) extends through the opening of the L-shaped telescopic channel (3432). The smoothing roller (3434) on 433) is still in contact with the elastic band, while the arc-shaped elastic pressure plate (3433) unfolds under the opening of the L-shaped telescopic channel (3432) and the positioning of the smoothing roller (3434). Under the elasticity of the arc-shaped elastic pressure plate (3433), the smoothing roller (3434) will be subjected to the elastic force of the arc-shaped elastic pressure plate (3433) to strengthen the squeezing of the elastic band, so as to prevent the thicker elastic band tube from still being uneven after the initial smoothing. In step S5, after the receiving unit (2) in step S4 is fully loaded, the elastic band is cut manually or by machine, and then the elastic band is connected to another receiving unit (2). The controller (36) controls the operation of the flipping component (33), and the flipping motor (334) drives the flipping shaft (332) to rotate. The flipping shaft (332) drives the flipping frame (333) to rotate 180 degrees clockwise or counterclockwise. The flipping frame (333) drives the smoothing component (34) to turn towards another receiving unit (2). The receiving and smoothing work in step S4 can be repeated. The staff disassembles and transports the fully loaded receiving unit (2), and finally assembles the empty receiving unit (2) to the base (1). The receiving work is carried out alternately until the elastic band is completely received.
