Description

Technical Field

[0001] The utility model relates to an auxiliary device, in particular to an auxiliary device for pulling out a bearing shaft and transferring a coiled material. Background Art

[0002] In the film coil production industry, the processed film materials need to be rolled and formed at the end of the production line. Usually, the winding device is equipped with a bearing shaft for carrying the film material. The bearing shaft needs to be regularly repaired or replaced to ensure the normal operation of the winding device. When the width of a specific type of film material is wider, the supporting bearing shaft also has a longer size. At the same time, the bearing shaft is usually an iron equipment and has a large weight. Specifically, a bearing shaft with a length of 3 meters and a diameter of 3 inches weighs nearly 100 kilograms. Therefore, during the extraction and disassembly process, multiple workers are required to work together to complete the disassembly operation, which is time-consuming and labor-intensive, and is also prone to safety hazards.

[0003] In a common device for extracting a bearing shaft, the whole device is fixed on the ground, and the bearing shaft is first clamped by a clamping mechanism, and then the clamping mechanism is driven by a moving mechanism to perform the extraction operation. However, the existing device cannot further transfer the coiled material after the bearing shaft is extracted, and the fixed equipment is often fixedly installed at the winding production line, occupying a large horizontal space in the workshop. At the same time, a set of device for extracting a bearing shaft can only be used in one production line, which increases production costs.

[0004] With respect to the above-mentioned related technologies, the applicant believes that the existing equipment is difficult to meet the operational requirements of extracting the bearing shaft and subsequently transferring the coiled material, and is difficult to meet actual production needs.

The lifting mechanism is connected to the rotating member, and the first bracket and the clamping mechanism are both connected to the power output end of the lifting mechanism. In this way, the height position of the clamping assembly and the lifting rod can be adjusted by the lifting mechanism, which is not limited by the size of the coil, making the auxiliary device more applicable. In addition, when transferring the coil, the coil can be lifted and lowered by the lifting mechanism to be detached or placed on the work surface.

[0017] There are many structural forms of the lifting mechanism, which can be in the form of a motor, a screw rod and a nut, or in the form of a lifting cylinder, but preferably, it also includes a connecting frame, the lifting mechanism includes a second bracket, a first screw rod, a screw rod nut connected to the first bracket, and a second motor for driving the first screw rod to rotate around its own axis, the clamping mechanism is connected to the first bracket, the second bracket is connected to the rotating member, the connecting frame is connected to the second bracket, the second motor is arranged on the second bracket, and one end of the first screw rod is connected to the output shaft of the second motor, and the screw rod nut is threadedly sleeved on the first screw rod.

[0018] In order to better guide the movement of the screw nut, two guide rails arranged side by side and spaced apart are provided on the second bracket, and the length direction of each guide rail is arranged along the length direction of the frame. The first screw is located between the two guide rails, and the screw nut is provided with a connecting plate connected to the first bracket, and the connecting plate is provided with a slider that slides with each guide rail.

[0019] There are various structural forms of the first driving mechanism, which can be in the form of a motor and gears, a motor, a worm wheel and a worm, or other forms. However, preferably, the first driving mechanism includes a third motor and a first gear, the first gear is mounted on the output shaft of the third motor, the rotating member is a second gear meshing with the first gear, the second gear is sleeved on the periphery of the output shaft of the second motor, and the second gear is connected to the second bracket, and the first screw rod is located between the lifting rod and the clamping assembly.

Since the frame can move toward or away from the coil tube core along the axial direction of the coil tube core, when the clamping assembly corresponds to the coil tube core, the clamping assembly clamps the bearing shaft in the coil tube core, and the bearing shaft is pulled out from the coil tube core by moving the frame away from the coil tube core; when the picking rod corresponds to the coil tube core, the frame moves toward the coil tube core so that the picking rod is inserted into the coil tube core, and the coil can be transferred and transported to another place by the movement of the frame later, so that the extraction of the bearing shaft and the transfer of the coil can be realized simultaneously through a set of auxiliary devices, which is convenient to operate and reduces the equipment manufacturing cost. In addition, this auxiliary device is mainly used to pull out the load-bearing shaft in the coil tube core after the plastic film is rolled up, and then transfer the coil to the designated work station, thereby reducing labor costs for the enterprise and improving production efficiency.

[0030] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the specific implementation of the utility model will be clearly and completely described below in conjunction with the accompanying drawings in the implementation of the utility model.

[0031] like Figures 1 to 7 As shown, the auxiliary device for extracting the bearing shaft and transferring the coil in this embodiment includes a frame 1 and a clamping mechanism 2, a film picking mechanism 3 and a steering mechanism 4 arranged on the frame 1. The length direction of the frame 1 is arranged along the vertical direction. In order to clearly illustrate the technical solution of this embodiment, Figure 1 The upper and lower are defined in .

[0032] The upper end of the frame 1 can be fixedly connected with a plurality of connection parts connected to the crane according to actual needs, and each connection part is located on the top surface of the frame 1. Driven by the crane, the frame 1 can move back and forth along the axial direction of the coil to approach or move away from the coil core. It should be understood that the auxiliary device in this embodiment can perform efficient extraction and disassembly operations on the load-bearing shafts in the industrial production field, such as common shafts such as pneumatic shafts. The frame 1 is mainly used to connect with the crane, thereby driving the auxiliary device to move as a whole. In addition, it can also drive the frame 1 to rotate.

[0033] like Figure 1 As shown, the steering mechanism 4 is arranged on the frame 1, and the steering mechanism 4 includes a first driving mechanism 41 and a rotating member, the power output end of the first driving mechanism 41 is drivingly connected to the rotating member, and the rotating member is rotatably connected to the frame 1. Figure 1 and Figure 2 As shown, the auxiliary device also includes a connecting frame 11, which is mainly used to carry functional component units such as the film picking mechanism and the clamping mechanism. The above-mentioned rotating member is fixedly connected to the connecting frame 11, so that the rotating member and the connecting frame 11 are driven by the first driving mechanism 41 to rotate around the vertical axis relative to the frame 1.

[0034] like Figure 1 As shown, the first driving mechanism 41 further includes a third motor 411 and a first gear 412. The third motor 411 is fixedly mounted on the frame 1, and the output shaft of the third motor 411 is arranged vertically. Figure 2 and Figure 3As shown, the first gear 412 is fixedly mounted on the output shaft of the third motor 411. The above-mentioned rotating member is specifically a second gear 42 meshing with the first gear 412. In this embodiment, the above-mentioned second gear 42 is an external gear slewing bearing, and the upper surface of the second gear 42 can be rotatably constrained on the bottom surface of the frame 1. Therefore, the rotation axis of the second gear 42 is also arranged along the vertical direction, and when the coil to be processed is kept flat on the workbench, the rotation axis of the second gear 42 can be kept perpendicular to the axis of the coil tube core. The above-mentioned first gear 412 rotates under the drive of the third motor 411. Since the first gear 412 and the second gear 42 are meshed, the second gear 42 rotates under the drive of the first gear 412, thereby indirectly driving the connecting frame 11 to rotate at the same speed.

[0035] The clamping mechanism 2 and the film picking mechanism 3 can also be lifted up and down. Figure 2 and Figure 4 As shown, the auxiliary device also includes a lifting mechanism 5, which is arranged on the connecting frame 11, and the clamping mechanism 2 and the film picking mechanism 3 are both connected to the power output end of the lifting mechanism 5. In this way, the lifting mechanism 5 drives the clamping mechanism 2 and the film picking mechanism 3 to reciprocate up and down. In some other embodiments, an external structure can also be used to realize the lifting and lowering of the clamping mechanism 2 and the film picking mechanism 3. Since the lifting mechanism 5 is located on the connecting frame 11 below the second gear 42, during the rotation of the second gear 42, the lifting mechanism 5, the clamping mechanism 2 and the film picking mechanism 3 rotate together with the second gear 42, that is, the steering of the lifting mechanism 5 and the circumferential position adjustment of the clamping mechanism 2 and the film picking mechanism 3 are realized.

[0036] like Figure 1 and Figure 4 As shown, the lifting mechanism 5 includes a second bracket 51, a first screw rod 52, a screw nut 54, and a second motor 55 for driving the first screw rod 52 to rotate around its own axis. Among them, the second bracket 51 is fixedly installed between the connecting frame 11 and the second gear 42, and the limiting structure extending downward from the second bracket 51 can be specifically selected to be triangular, rectangular, etc., and the limiting structure is fixedly connected to the connecting frame 11. The second motor 55 is installed above the second bracket 51 and is located in the frame structure formed by the frame 1 to achieve reasonable space allocation and protect the second motor 55 as a driving source. The above-mentioned second gear 42 and the first gear 412 are both located between the second bracket 51 and the frame 1, and the lower surface of the second gear 42 is fixedly connected to the top surface of the second bracket 51. In addition, the above-mentioned second gear 42 is sleeved on the periphery of the output shaft of the second motor 55, so when the second gear 42 rotates, it will rotate around the output shaft of the second motor 55, that is, the rotation axis of the output shaft of the second motor 55 is set along the above-mentioned vertical axis.

[0037] At the same time, the length direction of the first screw rod 52 is also arranged along the vertical direction, and the upper end of the first screw rod 52 is fixedly connected to the output shaft of the second motor 55. In this embodiment, both ends of the first screw rod 52 are fixed by bearing seats 53, and each bearing seat 53 is arranged on the connecting frame 11. The screw nut 54 is threadedly connected to the first screw rod 52 and is connected to the film picking mechanism 3. In this way, under the drive of the second motor 55, the first screw rod 52 rotates around its own axis. Since the screw nut 54 is threadedly connected to the first screw rod 52, the film picking mechanism 3 is arranged on the screw nut 54 and is connected to the clamping mechanism 2. Then, during the clockwise or counterclockwise rotation of the first screw rod 52, the clamping mechanism 2 and the film picking mechanism 3 will move upward or downward synchronously.

[0038] like Figure 2 and Figure 4 As shown, the connecting frame 11 is also provided with two guide rails 511 arranged side by side and extending vertically, and the first screw rod 52 is located in the middle of the two guide rails 511. Figure 2 As shown, the film lifting mechanism 3 includes a first bracket 31 and a lifting rod 32 that can be inserted into or withdrawn from the coil tube core. A connecting plate 541 is fixedly mounted on the screw nut 54, and the connecting plate 541 is vertically arranged, and the side of the connecting plate 541 facing away from the screw nut 54 is detachably connected to the first bracket 31, and the detachable connection method includes but is not limited to bolt connection, so that when the film lifting mechanism 3 needs to be disassembled and repaired, the staff can disassemble and assemble it more quickly.

[0039] like Figure 4 As shown, a plurality of sliders 5411 that slide with the guide rail 511 are correspondingly mounted on the connecting plate 541. In this way, the movement of the screw nut 54 is guided by the sliding cooperation between the guide rail 511 and the slider 5411, and the limiting structure extended from the second bracket 51 can further prevent the first bracket 31 from deflecting when it is lifted up and down, thereby improving the reliability of the auxiliary device during operation.

[0040] like Figure 5 and Figure 6 As shown, for the film lifting mechanism 3, the lifting rod 32 is rotatably connected to the first bracket 31. In this embodiment, as shown in FIG. Figure 5 As shown, when the lifting rod 32 is needed to move the coil, the lifting rod 32 is rotated until its length direction is consistent with the axial direction of the coil tube core, and then the lifting rod 32 is slowly inserted into the coil tube core by the driving of the crane, and finally the lifting mechanism 5 is used to lift the coil, and the auxiliary device is moved to the expected position together with the coil in cooperation with the driving. Figure 6As shown, the lifting rod 32 is rotated until its length direction is consistent with the vertical direction, so that the lifting rod 32 can be folded and stored in a position close to the first bracket 31, further improving the space utilization rate of the auxiliary device and preventing the lifting rod 32 from blocking other surrounding equipment or staff when placed horizontally. At the same time, when the lifting rod 32 is in the storage state, multiple fixings, including but not limited to buckles, etc., can be installed on the first bracket to ensure that the lifting rod 32 will not easily slide down and cause injuries to staff.

[0041] In order to control and drive the lifting rod 32 to rotate, the film lifting mechanism 3 also includes a second driving mechanism 33 for driving the lifting rod 32 to rotate. The second driving mechanism 33 is arranged on the first bracket 31, and the power output end of the second driving mechanism 33 is connected to the end of the lifting rod 32 close to the first bracket 31. The second driving mechanism 33 includes a rotating shaft 331 and a first motor 332 for driving the rotating shaft 331 to rotate around its own axis. The first motor 332 is installed on the first bracket 31, one end of the rotating shaft 331 is connected to the output shaft of the first motor 332, and the rotating shaft 331 is installed on the first bracket 31 through a first bearing 35. The lifting rod 32 intersects with the rotating shaft 331, and the end of the lifting rod 32 close to the first bracket 31 is fixedly installed on the other end of the rotating shaft 331. In addition, the second driving mechanism 33 can also be in the form of a push rod motor. For example, the lifting rod 32 is passed through the first bracket 31, and the output shaft of the push rod motor drives the end of the lifting rod close to the first bracket 31 to move up and down, so as to realize the horizontal working state and the vertical storage state of the lifting rod 32.

[0042] like Figure 1 , Figure 2 and Figure 7 As shown, the clamping mechanism 2 includes a clamping assembly 21, a third bracket 22 and a third driving mechanism 23. The third bracket 22 is fixedly connected to the lower part of the first bracket 31 through a mounting bracket 34. In this embodiment, there are two mounting brackets 34 and they are arranged relatively spaced apart, and the first bracket 31 is located between the two mounting brackets 34. The clamping assembly 21 is used to clamp or loosen the bearing shaft 6 in the coil tube core, and the clamping assembly 21 includes a first clamping plate 211 and a second clamping plate 212 arranged in sequence along the radial direction of the bearing shaft 6. The first clamping plate 211 and the second clamping plate 212 are close to each other and are jointly surrounded to form a clamping groove 213 that matches the peripheral wall of the bearing shaft 6, wherein the inner sides of the first clamping plate 211 and the second clamping plate 212 close to each other are both covered with rubber skin, so as to increase the friction between the bearing shaft 6 and avoid scratches on the shaft wall of the bearing shaft 6.

[0043] like Figure 7As shown, the third driving mechanism 23 is used to drive the first clamping plate 211 and the second clamping plate 212 to move closer to or away from each other. Specifically, the third driving mechanism 23 is installed on the third bracket 22. The clamping mechanism 2 also includes a second screw rod 231, a first nut 232 fixedly connected to the first clamping plate 211, a second nut 233 fixedly connected to the second clamping plate 212, and a fourth motor 234 used to drive the second screw rod 231 to rotate around its own axis. Among them, the second screw rod 231 is connected to the output shaft of the fourth motor 234, and the second bearings 24 are installed at both ends of the second screw rod 231, and are assembled at the corresponding position of the third bracket 22 through the corresponding second bearings 24. The aforementioned second screw rod 231 has a first thread segment and a second thread segment arranged in sequence along its axial direction and with opposite thread rotation directions, the first nut 232 is threadedly connected to the first thread segment, and the second nut 233 is threadedly connected to the second thread segment. In this way, driven by the fourth motor 234, the second screw rod 231 rotates around its own axis. Since the rotation directions of the first thread segment and the second thread segment on the second screw rod are opposite, the first nut 232 and the second nut 233 move toward each other or away from each other, thereby correspondingly clamping or loosening the clamping assembly 21.

[0044] The clamping mechanism 2, the film picking mechanism 3 and the lifting mechanism 5 are in the following two states when the second gear 42 rotates together: the clamping groove 213 of the clamping assembly 21 corresponds to the coil tube core and is in the state of pre-clamping the bearing shaft; and the horizontally placed picking rod 32 corresponds to the coil tube core and is in the state of pre-inserting the coil tube core. In this embodiment, the clamping groove 213 and the picking rod 32 are arranged to be separated from each other, so when the second gear 42 rotates 180°, the state of pre-clamping the bearing shaft and the state of pre-inserting the coil tube core are switched.

[0045] The first motor 332, the second motor 55, the third motor 411 and the fourth motor 234 in the above-mentioned auxiliary device are all controlled by a control system. The control system includes photoelectric sensors, laser radars, proximity switches, relays, contactors, circuit breakers, PLCs, servo controllers, control programs, etc. Among them, electrical components such as relays, contactors, circuit breakers, PLCs, servo controllers, and control programs constitute a control box. According to the sensor signals of photoelectric sensors, laser radars, proximity switches, etc., the control program realizes the functions of pulling out the load-bearing shaft 6, transplanting and picking the film, etc. The working principle of the specific control system is similar to that in the prior art, and will not be described in detail in this embodiment. In addition, the roll diameter and width of the product can be automatically calculated by inputting relevant product parameters into the system, and the flexibility is high.

[0046] The working process of the above auxiliary device is as follows:

[0047] When on standby, the lifting rod 32 is arranged vertically, and the auxiliary device is parked at a designated position that does not affect the passage of workers or materials. When a coiled product is completed on a production line, the crane drives the auxiliary device to move to the position of the bearing shaft 6 to be taken, and the clamping groove 213 of the clamping mechanism 2 faces the coil.

[0048] After the operator confirms that it is in place, he inputs the product roll diameter on the control system and presses the execution button. The second motor 55 drives the first screw 52 to rotate, so that the clamping mechanism 2 and the film picking mechanism 3 simultaneously descend to the clamping groove 213 and correspond to the bearing shaft 6 in the coil tube core. The driving drive drives the frame 1 to move axially along the bearing shaft 6 until it moves to the pre-clamping station for pre-clamping the bearing shaft 6. The fourth motor 234 drives the second screw 231 to rotate, and the first clamping plate 211 and the second clamping plate 212 approach each other to clamp the bearing shaft 6. Then the driving moves away from the coil, so that the bearing shaft 6 is extracted from the coil tube core and pre-placed in the specified position. Subsequently, the fourth motor 234 reverses, and the first clamping plate 211 and the second clamping plate 212 move away from each other to release the bearing shaft 6. The second motor 55 rotates in the opposite direction, and through the reverse rotation of the first screw 52, ​​the clamping mechanism 2 moves upward and disengages from the bearing shaft 6.

[0049] The crane moves again to move the auxiliary device to the pre-clamping station, and then the third motor 411 drives the first gear 412 to rotate, the first gear 412 drives the second gear 42 to rotate, and the second gear 42 drives the clamping mechanism 2 and the film picking mechanism 3 to rotate 180°, so that the clamping mechanism 2 and the film picking mechanism 3 are swapped, that is, switched from the pre-clamping load-bearing shaft 6 state to the pre-insertion coil tube core state. At this time, the picking rod 32 of the film picking mechanism 3 is facing the coil tube core.

[0050] The first motor 332 rotates to drive the rotating shaft 331 to rotate, so that the lifting rod 32 is rotated to a horizontal position, that is, arranged along the axial direction of the coil. The second motor 55 drives the first screw rod 52 to rotate, so that the clamping mechanism 2 and the film lifting mechanism 3 are simultaneously lowered to a specified height, so that the lifting rod 32 corresponds to the coil tube core. Subsequently, the crane moves toward the coil along the axial direction of the coil. When the lifting rod 32 is completely inserted into the coil tube core, the second motor 55 rotates in the opposite direction. Through the reverse rotation of the first screw rod 52, the film lifting mechanism 3 moves upward until the coil is separated from the work surface. Then, after the coil is transported to the designated work station by the crane, the second motor 55 rotates forward, and the film lifting mechanism 3 descends. When the lowest point of the coil contacts the designated work surface, the lowering stops, that is, the second motor 55 in the lifting mechanism stops working. Subsequently, the crane moves along the axial direction of the coil in a direction away from the coil until the lifting rod 32 is separated from the coil. The first motor 332 rotates in the reverse direction, driving the rotating shaft 331 to rotate in the reverse direction, and then the lifting rod 32 is turned to a vertically arranged storage state.

[0051] The vehicle moves and moves the auxiliary device to the standby position, waiting for the next call to be executed.

[0052] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.
