Description

Technical Field

[0001] The present invention belongs to the technical field of coil equipment, and particularly relates to a coil replacement device and a control method for coil replacement. Background Art

[0002] The coil used in production and manufacturing is wound around a coil shaft and the coil is released for use as the coil shaft rotates. The coil shafts equipped in the existing equipment are generally one roll. After it is used up, a full roll of idle coil is manually pulled in and replaced. First, since there is only one fixed position for the coil shaft, two coil shafts need to be pulled for replacement. The coil shaft and the coil are relatively heavy, so it is very laborious to replace them. Overall, it is also very time-consuming, and multiple people are required to cooperate for replacement, which is labor-intensive and increases the personnel cost. Moreover, during the replacement process, the position needs to be aligned, which has certain requirements for manual operation. During film replacement, there may be a deviation of the coil due to inaccurate subjective judgment of people, and further alignment and deviation correction are required. Summary of the Invention

[0003] In view of the deficiencies of the existing technology, the present invention provides a coil replacement device and a control method for coil replacement to solve the problem of manual coil replacement in the prior art.

[0004] To solve the above technical problems, the first technical solution provided by the present invention is as follows: A coil replacement device includes a left film laying mechanism and a right film laying mechanism;

[0005] The left film laying mechanism includes a left coil base, on which a left coil shaft is rotatably arranged, and a left coil is wound around the left coil shaft; a left vertical bracket is fixed on the left coil base, a left rotating shaft is rotatably connected to the left vertical bracket, the left rotating shaft is connected to a left servo motor, both ends of the left rotating shaft are respectively connected to a left end rod, and a left fixing rod parallel to the left rotating shaft is connected between the two left end rods; a left driving roller is arranged in parallel under the left rotating shaft;

[0006] The right film laying mechanism has the same structure as the left film laying mechanism and is symmetrically arranged. The right film laying mechanism includes a right coil base, on which a right coil shaft is rotatably arranged, and a right coil is wound around the right coil shaft; a right vertical bracket is fixed on the right coil base, the top of the right vertical bracket is rotatably connected to a right rotating shaft, the right rotating shaft is connected to a right servo motor, both ends of the right rotating shaft are respectively connected to a right end rod, and a right fixing rod parallel to the right rotating shaft is connected between the two right end rods; a right driving roller is arranged in parallel under the right rotating shaft;

[0007] A guide roller is arranged between the left rotating shaft and the right rotating shaft and at a position higher than the left rotating shaft;

[0008] One of the left coil shaft and the right coil shaft is used as a spare, and the other is replaced when it is nearly exhausted; in the use state, the left coil sequentially passes under the left driving roller and under the guide roller, passes out from above the guide roller and continues to drive to the left, and the right coil sequentially passes under the right driving roller and above the guide roller, passes out from above the guide roller and continues to drive to the left; in the spare state, the end of the left coil is placed on the left fixed rod, and the end of the right coil is placed on the right fixed rod;

[0009] The coil replacement device further includes double-sided adhesives for adhering to the left coil on the left fixed rod and for adhering to the right coil on the right fixed rod;

[0010] During the flipping process of the left rotating shaft, the left fixed rod will touch the right coil between the right driving roller and the guide roller; during the flipping process of the right rotating shaft, the right fixed rod will touch the left coil between the left driving roller and the guide roller.

[0011] Through the above technical solution, using the left film laying mechanism and the right film laying mechanism to replace the coils with each other can greatly reduce the number of workers, reduce labor costs, and the replacement process is faster and more labor-saving.

This technical solution simplifies and saves labor in the previous operation process of replacing the coil, that is, transporting the left coil base and the right coil base to the set position. It only needs to push the left coil base and the right coil base along the left guide rail and the right guide rail to the limited position. The positions of the left coil base and the right coil base are limited, that is, the in-place positions are determined, and no manual positioning is required, with high accuracy.

[0014] The present invention is further configured such that the double-sided tape is disposed on the tape pasting mechanism, and the tape pasting mechanism further includes a bottom plate, a support plate, and two fixing plates. The bottom plate is horizontally arranged, the support plate is vertically connected to the bottom plate, and the two fixing plates are connected to the support plate in a V shape. A left double-sided tape plate is provided on the outer side surface of the left fixing plate, and a right double-sided tape plate is provided on the outer side surface of the right fixing plate. A plurality of layers of straight strip-shaped double-sided tapes are fixed on the left double-sided tape plate and the right double-sided tape plate. The tape pasting mechanism is liftable. When the fixing plate is at the lowest position, the left tube body will not touch the double-sided tape on the left double-sided tape plate during the rotation of the left rotating shaft, and the right tube body will not touch the double-sided tape on the right double-sided tape plate during the rotation of the right rotating shaft. When the fixing plate is lifted, the left coil adsorbed by the left tube body is pressed onto the double-sided tape of the left double-sided tape plate during the rotation of the left rotating shaft, and the right coil adsorbed by the right tube body is pressed onto the double-sided tape of the right double-sided tape plate during the rotation of the right rotating shaft.

[0015] The present invention is further configured such that the lengths of the left double-sided tape plate and the right double-sided tape plate are greater than the length of the double-sided tape. Two U-shaped grooves are fixed at both ends of the fixing plate. The openings of the U-shaped grooves face each other. The two U-shaped grooves are used to insert and fix the two ends of the left double-sided tape plate and the right double-sided tape plate. The connection between the bottom of the U-shaped groove and the fixing plate is closed.

[0016] The present invention is further configured such that a release paper is provided between the double-sided tapes.

A second score line is provided in the width direction of the empty section between the tear tab and the end of the empty section. Hold the tear tab and pull it open along the second score line, and then continue to pull it open along the first score line to tear off the entire release paper.

[0018] The present invention is further configured such that vacuum degree detection sensors are provided on both the left tube body and the right tube body, and the vacuum degree detection sensors are externally connected to a PLC controller; the left servo motor is connected to a left motor driver, the right servo motor is connected to a right motor driver, and the left motor driver and the right motor driver are connected to the PLC controller; the support plate is a liftable rod, or a liftable mechanism is provided at the bottom of the bottom plate, and the liftable mechanism includes a lift driving device, and the lift driving device is connected to the PLC controller.

[0019] The second technical solution provided by the present invention is as follows: A control method for coil replacement, using the above-mentioned coil replacement device, taking the situation that the right coil is nearly exhausted and the left coil needs to be replaced as an example, includes the following steps:

[0020] (1) During operation, the right coil bypasses from the bottom of the right driving roller and passes through from the top of the guide roller to the left for transmission. At this time, the fixing plate is in the low position, and the left fixing rod and the right fixing rod naturally fall by gravity.

[0021] (2) When the right coil is nearly exhausted, the PLC controller controls the lift driving device to drive the fixing plate to rise, and the vacuum adsorption mechanism evacuates the left tube body. When the vacuum degree reaches a predetermined value, the left servo motor drives the left rotating shaft to rotate and lift, and the left tube body adsorbs the left coil and presses it against the left double-sided adhesive plate and adheres to the double-sided adhesive to take it away.

[0022] (3) The left servo motor drives the left rotating shaft to rotate in the reverse direction to lower, the fixing plate drops to the low position, and the left servo motor drives the left rotating shaft to rotate and rise again until it presses on the right coil between the guide roller and the right driving roller, and the double-sided adhesive bonds the left coil and the right coil together.

[0023] (4) The vacuum adsorption mechanism stops evacuating the left tube body, releases the left coil, the end of the left coil and the tail of the right coil continue to be transmitted forward together, and the left servo motor drives the left rotating shaft to rotate and lower to return to the original position.

[0024] When the left coil is nearly exhausted and the right coil needs to be replaced, it is the same as the above steps.

[0025] The coil replacement device of the present invention can save labor, time and effort. For specific beneficial effects, please refer to the specific implementation manners. Description of the Drawings

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0032] The present invention provides a coiled material replacement device, including a left film - laying mechanism 100 and a right film - laying mechanism 200, as can be seen in Figure 1 .

[0033] Among them, the left film - laying mechanism 100 includes a left coiled material base 1, on which a left coiled material shaft 2 is rotatably arranged, and a left - hand side coiled material 3 is wound around the left coiled material shaft 2; a left vertical support 4 is fixed on the left coiled material base 1, a left rotating shaft 5 is rotatably connected to the left vertical support 4, the left rotating shaft 5 is connected to a left servo motor 7, both ends of the left rotating shaft 5 are respectively connected to a left - hand side end rod 6, and a left fixing rod parallel to the left rotating shaft 5 is connected between the two left - hand side end rods 6 (the left fixing rod is in Figure 1(blocked in the figure), a left drive roller 8 is provided in parallel below the left rotating shaft 5. The right film covering mechanism 200 and the left film covering mechanism 100 have the same structure and are arranged axially symmetrically (the reference numerals of the right film covering mechanism 200 in the attached drawings are not marked again). The right film covering mechanism 200 includes a right coil base, on which a right coil shaft is rotatably provided, and a right-side coil is wound on the right coil shaft; a right vertical bracket is fixed on the right coil base, and the top of the right vertical bracket is rotatably connected to a right rotating shaft, the right rotating shaft is connected to a right servo motor, both ends of the right rotating shaft are respectively connected to a right-side end rod, and a right fixed rod parallel to the right rotating shaft is connected between the two right-side end rods, and a right drive roller is provided in parallel below the right rotating shaft.

[0034] A guide roller 300 is provided between the left rotating shaft 5 and the right rotating shaft and above the left rotating shaft 5. One of the left coil shaft 2 and the right coil shaft is used as a spare, and the other is replaced when it is almost exhausted; in the use state, the left-side coil 3 sequentially bypasses below the left drive roller 8 and below the guide roller 300, passes out from above the guide roller 300 and continues to be transmitted to the left, and the right-side coil sequentially bypasses below the right drive roller and above the guide roller 300, passes out from above the guide roller 300 and continues to be transmitted to the left; in the spare state, the end of the left-side coil 3 is placed on the left fixed rod, and the end of the right-side coil is placed on the right fixed rod.

[0035] The coil replacement device further includes double-sided tape for adhering to the left-side coil 3 on the left fixed rod and for adhering to the right-side coil on the right fixed rod.

[0036] During the flipping process of the left rotating shaft 5, the left fixed rod will touch the right-side coil between the right drive roller and the guide roller 300; during the flipping process of the right rotating shaft, the right fixed rod will touch the left-side coil 3 between the left drive roller 8 and the guide roller 300.

[0037] The coil replacement device of the present invention uses a left film laying mechanism 100 and a right film laying mechanism 200 to replace coils with each other. Specifically, when it is necessary to replace the right coil shaft, the double-sided tape is adhered to the left coil 3 on the left fixed rod, and it is lifted by the rotation of the left rotating shaft, and the double-sided tape is simultaneously adhered to the right coil between the right driving roller and the guide roller 300 to realize the use of the left coil 3 and the replacement of the right coil shaft. When it is necessary to replace the left coil shaft 2, the double-sided tape is adhered to the right coil on the right fixed rod, and it is lifted by the rotation of the right rotating shaft, and the double-sided tape is simultaneously adhered to the left coil 3 between the left driving roller 8 and the guide roller 300 to realize the use of the right coil and the replacement of the left coil shaft 2. It should be noted that the first adhesion of the double-sided tape here can be manual adhesion or can be carried out using the tape adhering mechanism 400. The tape adhering mechanism 400 includes publicly available equipment and the new tape adhering mechanism 400 mentioned below. The second adhesion of the double-sided tape is to adhere it to the coil to be used by the stickiness of the double-sided tape itself. When using the coil replacement device of the present invention, only one person is needed for tape adhesion, or the tape adhesion can be completely carried out by the tape adhering mechanism 400, which can greatly reduce the number of workers, reduce labor costs, and the replacement process is faster and more labor-saving.

[0038] In order to facilitate the transportation of the left coil base 1 to the working position of the right coil base, a left guide rail 9 is slidably provided at the bottom of the left coil base 1, and a right guide rail 10 is slidably provided at the bottom of the right coil base. The left guide rail 9 and the right guide rail 10 are arranged in parallel and parallel to the left rotating shaft 5. A left limit block for restricting the left coil base 1 to run in place is provided on the left guide rail 9, and a right limit block for restricting the right coil base to run in place is provided on the right guide rail 10. The left coil 3 and the right coil are in a one-use-one-spare state. After film laying, only the coil base with the exhausted coil needs to be pulled out and a new coil base is pushed in. The first form of the slidable setting mentioned here includes the cooperation mode of the guide rail with the slider or the roller, and the slider or the roller is fixed under the left coil base 1 and the right coil base. The second form of the slidable setting is to adopt the mode driven by the linear guide rail. The linear guide rail is a mature existing structure and is driven by a motor. At this time, the motor can also be controlled by connecting a PLC controller, which can be completely separated from manual pushing and is more labor-saving. The corresponding limit block can be replaced with a limit switch. Once in place, the limit switch is triggered, and the signal of the movement in place can be transmitted to the PLC controller. The PLC controller then controls the motor to stop working, and the left coil base 1 and / or the right coil base are transported in place.

[0039] In the above structural description, the left coil 3 is placed on the left fixed rod by its own gravity, and the right coil is placed on the right fixed rod by its own gravity. During the rotation with the rotating shaft, if the air flow is unstable, the coil may not be completely attached to the left fixed rod or the right fixed rod. To completely avoid this phenomenon, a left tube body 11 is fixed on the left fixed rod. A plurality of suction holes 12 for adsorbing the left coil 3 are formed in the left tube body 11, and a left exhaust hole is formed in the left tube body 11; a right tube body is fixed on the right fixed rod. A plurality of suction holes 12 for adsorbing the right coil are formed in the right tube body, and a right exhaust hole is formed in the right tube body; the left exhaust hole and the right exhaust port are externally connected to a vacuum adsorption mechanism. By sucking air from the left exhaust hole / right exhaust hole through the externally connected vacuum adsorption mechanism, the left coil 3 / right coil placed on the suction port is adsorbed on the suction port, so that the random rotation of the rotating shaft will not affect the flatness of the coil.

[0040] In the foregoing embodiments, it is mentioned that the adhesion of the double-sided tape can be manually pasted or pasted using an existing tape pasting mechanism 400. The present invention provides a new type of tape pasting mechanism 400, which can be seen Figure 1 and Figure 2 , the double-sided tape is arranged on the tape pasting mechanism 400. The tape pasting mechanism 400 further includes a bottom plate 13, a support plate 14 and two fixing plates 15. The bottom plate 13 is horizontally arranged, the support plate 14 is vertically connected to the bottom plate 13, and the two fixing plates 15 are connected to the support plate 14 in a V shape. A left double-sided tape plate is arranged on the outer side surface of the left fixing plate 15, and a right double-sided tape plate is arranged on the outer side surface of the right fixing plate 15. A plurality of layers of straight double-sided tapes are fixed on the left double-sided tape plate and the right double-sided tape plate. The tape pasting mechanism 400 plate is liftable. When the fixing plate 15 is at the lowest position, the left tube body 11 will not touch the double-sided tape on the left double-sided tape plate during the rotation of the left rotating shaft 5, and the right tube body will not touch the double-sided tape on the right double-sided tape plate during the rotation of the right rotating shaft; when the fixing plate 15 is raised, the left coil 3 adsorbed by the left tube body 11 presses on the double-sided tape of the left double-sided tape plate during the rotation of the left rotating shaft 5, and the right coil adsorbed by the right tube body presses on the double-sided tape of the right double-sided tape plate during the rotation of the right rotating shaft. The reason why the two fixing plates 15 are in a V shape is that when the fixing plate 15 is raised during tape pasting, when the left tube body 11 rotates to the left double-sided tape plate, the left coil 3 on the left tube body 11 can just press on the left double-sided tape plate head-on for gluing, and when the right tube body rotates to the right double-sided tape plate, the right coil on the right tube body can just press on the right double-sided tape plate head-on for gluing. Therefore, preferably, the left tube body 11 is fixed on the right side surface of the left fixed rod close to the left double-sided tape plate, and the right tube body is fixed on the left side surface of the right fixed rod close to the right double-sided tape plate.

[0041] The lengths of the left double-sided adhesive plate and the right double-sided adhesive plate are greater than the length of the double-sided adhesive. At both ends of the fixing plate 15, two U-shaped grooves 16 are fixed. The openings of the U-shaped grooves 16 face each other. The two U-shaped grooves 16 are used to insert and fix the two ends of the left double-sided adhesive plate and the right double-sided adhesive plate. The connection between the bottom of the U-shaped groove 16 and the fixing plate 15 is closed. Refer to Figure 2 . In this way, when the left double-sided adhesive plate and / or the right double-sided adhesive plate are used up, it is convenient to replace them with new ones.

[0042] As a structure of the double-sided adhesive applicable to the present invention, refer to Figure 3 . Between all the straight strip double-sided adhesives, there is an anti-sticking paper 17. The anti-sticking paper 17 is continuously folded into multiple small anti-sticking units 18. Between every two anti-sticking units 18, there is a double-sided adhesive adhered. Between every two anti-sticking units 18, there are discontinuous first score lines 20 at the folding place. The anti-sticking unit 18 includes an adhesion section 18-1 for adhering the double-sided adhesive and empty sections 18-2 connected to both ends of the adhesion section 18-1. The ends of all the empty sections 18-2 are fixed together. When in use, tear from the empty section 18-2 at one end, and pull one end of the anti-sticking unit 18 along the first score line 20 until the other end, then the whole anti-sticking unit 18 can be pulled down, exposing the internal double-sided adhesive, and the operation is simple.

[0043] Furthermore, a tear tab 22 is connected to the side of the empty section 18-2. The adjacent outer tear tabs 22 and inner tear tabs 22 are respectively located on the two sides of the empty section 18-2. All the tear tabs 22 are arranged at intervals, one above the other. Between the tear tab 22 and the end of the empty section 18-2, there is a second score line 21 along the width direction of the empty section 18-2. Pull the tear tab 22 along the second score line 21 to open, and then continue to pull along the first score line 20, and then the whole anti-sticking paper 17 can be torn off. The operation is simpler and more convenient. The tear tabs 22 arranged at intervals, one above the other, are staggered, which can better prevent mis-pulling. Specifically, refer to Figure 4 . Pull the tear tab 22 (at point A), open a slit 23 along the second score line 21 of the first layer, and then tear off the first layer of anti-sticking unit 18 along the first score line 20 between the first layer and the second layer. The tear tab 22 (at point B) is connected to the bottom surface of the second layer of anti-sticking unit 18, so it will not be torn off. When using one layer of double-sided adhesive 19 for one time of film covering, when it is necessary to use the next layer of double-sided adhesive 19, pull the tear tab 22 (at point B), open along the second score line 21 of the second layer, and then tear off the second layer of anti-sticking unit 18 along the first score line 20 between the second layer and the third layer. The tear tab 22 of the third layer is connected to the bottom surface of the third layer of anti-sticking unit 18, so it will not be torn off ( Figure 4 the tear tab of the third layer in

[0044] As a preferred embodiment of the present invention, vacuum degree detection sensors are provided on both the left tube body 11 and the right tube body to detect the vacuum degree. The greater the vacuum degree, the greater the adsorption force on the coil material. An appropriate vacuum degree is sufficient, which can be determined according to the actually used coil material, the number and size of the air suction holes 12, etc. The vacuum degree detection sensors are externally connected to the PLC controller to transmit the detected data to the PLC controller. The PLC controller gives instructions on whether the vacuum adsorption mechanism works or not according to the magnitude of the vacuum degree. The left servo motor 7 is connected to the left motor driver, and the right servo motor is connected to the right motor driver. The left motor driver and the right motor driver are connected to the PLC controller. The PLC controller gives instructions to the left motor driver and the right motor driver to control the operation of the left servo motor 7 and the right servo motor. The operation includes forward rotation and reverse rotation. The support plate 14 is a liftable rod, or a liftable mechanism is provided at the bottom of the bottom plate 13. The liftable mechanism includes a lift driving device, and the lift driving device is connected to the PLC controller. Both the liftable mechanism and the lift driving device use existing devices, such as various lift structures such as lift rods and diamond folding frames, and structures controlled by using cylinders, hydraulic cylinders, electric cylinders, linear motors, etc. as the lift driving device.

[0045] As a control method for replacing the coil material of the above coil material replacement device, taking the situation that the coil material on the right side is nearly exhausted and the coil material on the left side 3 needs to be replaced as an example, it includes the following steps:

[0046] (1) During operation, the coil material on the right side bypasses from the bottom of the right transmission roller and passes through from the top of the guide roller 300 to the left for transmission. At this time, the fixing plate 15 is in the low position, and the left fixing rod and the right fixing rod are naturally lowered by gravity.

[0047] (2) When the coil material on the right side is nearly exhausted, the PLC controller controls the lift driving device to drive the fixing plate 15 to rise, and the vacuum adsorption mechanism evacuates the left tube body 11. When the vacuum degree reaches the predetermined value, the left servo motor 7 drives the left rotating shaft 5 to rotate and lift, and the left tube body 11 adsorbs the coil material on the left side 3 and presses it against the left double-sided adhesive plate and adheres to the double-sided adhesive to take it away.

[0048] (3) The left servo motor 7 drives the left rotating shaft 5 to rotate in the reverse direction to lower, and fixes it to the low position. The left servo motor 7 drives the left rotating shaft 5 to rotate and rise again until it presses on the coil material on the right side between the guide roller 300 and the right transmission roller, and the double-sided adhesive bonds the coil material on the left side 3 and the coil material on the right side together.

[0049] (4) The vacuum adsorption mechanism stops evacuating the left tube body 11, releases the coil material on the left side 3, and the end of the coil material on the left side 3 and the tail of the coil material on the right side continue to be transmitted forward together. The left servo motor 7 drives the left rotating shaft 5 to rotate and lower to return to its original position.

[0050] When the coil material on the left side 3 is nearly exhausted and the coil material on the right side needs to be replaced, the replacement control method is the same as the above steps.

[0051] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.

4. A control method for roll replacement, using the roll replacement device according to claim 3, characterized in that, Taking the situation that the right coil is nearly used up and the left coil needs to be replaced as an example, it includes the following steps: (1) During operation, the right-side coil passes around the bottom of the right drive roller and exits from the top of the guide roller to the left for transmission. At this time, the fixed plate is in the low position, and the left fixed rod and the right fixed rod naturally drop by gravity. (2) When the right-side coil is nearly exhausted, the PLC controller controls the lifting drive device to drive the fixed plate to rise. The vacuum adsorption mechanism evacuates the left tube body. When the vacuum degree reaches the predetermined value, the left servo motor drives the left rotating shaft to rotate and lift. The left tube body adsorbs the left-side coil and presses it against the left double-sided adhesive board, and adheres to the double-sided adhesive to take it away. (3) The left servo motor drives the left rotating shaft to rotate in the reverse direction to lower, the fixed plate drops to the low position, and the left servo motor drives the left rotating shaft to rotate and rise again until it presses on the right-side coil between the guide roller and the right drive roller. The double-sided adhesive bonds the left-side coil and the right-side coil together. (4) The vacuum adsorption mechanism stops evacuating the left tube body, releases the left-side coil. The end of the left-side coil and the tail of the right-side coil continue to be transmitted forward together, and the left servo motor drives the left rotating shaft to rotate and lower to return to the original position. When the left-side coil is nearly exhausted and the right-side coil needs to be replaced, the steps are the same as above.
