Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of winding, and particularly relates to a device and method for automatically winding adhesive tape on a winding shaft. Background Art
[0002] After the film is wound by a winding shaft, a film roll is formed. Classified by the destination of the film roll, the film roll can be divided into two categories. The first category is that the film roll flows to the market as a finished product; the second category is that the film roll flows to other workshops of the factory as a semi-finished product for further processing, and the film roll needs to be gradually unwound during the further processing. Before winding the first category of film roll, a paper core tube needs to be sleeved outside the winding shaft. After winding, the winding shaft is pulled out from the paper core tube, and the paper core tube together with the film roll flows to the market. The above-mentioned winding shaft needs to be selected as an air shaft to facilitate the paper core tube to be tightened during winding and pulled out after winding; while for the second category of film roll, the paper core tube can be omitted, that is, the film is directly wound by a winding shaft made of metal material, which not only saves the paper core tube, but also does not need to select and use an air shaft, and an ordinary winding shaft can be used for winding. Of course, before winding the second category of film roll, an adhesive tape needs to be wound on the surface of the winding shaft. The wound adhesive tape is in a spiral shape, and the non-adhesive surface of the adhesive tape (i.e., the side without coating the adhesive) is attached to the surface of the winding shaft, while the adhesive side of the adhesive tape (i.e., the side coated with the adhesive) faces away from the surface of the winding shaft, so that the film can be adhered to the surface of the winding shaft.
[0003] The process of winding the adhesive tape on the winding shaft of the traditional second category of film roll is completed manually. It is not easy for the adhesive tape to be tightly and compactly attached to the surface of the winding shaft, and it is easy to be loose and wrinkled, which affects the bottoming quality of the film roll; in addition, when the length of the winding shaft is large, it is time-consuming and laborious, and the winding process needs to be carried out in sections. Summary of the Invention
[0004] The purpose of the present invention is to overcome the above-mentioned drawbacks and provide a device and method for automatically winding adhesive tape on a winding shaft, which can automatically wind the adhesive tape on the surface of the winding shaft and make the adhesive tape tightly attached to the surface of the winding shaft without generating wrinkles.
[0005] The present invention can be implemented as follows: An apparatus for automatically winding adhesive tape on a winding shaft includes a frame on which a winding shaft is placed. The extending direction of the central axis of the winding shaft is longitudinal, and there is also a winding shaft motor for driving the winding shaft to rotate. Its main feature is that a first-stage support capable of longitudinal movement and a lead screw mechanism for driving the first-stage support to move longitudinally are also installed on the frame; a second-stage support capable of transverse movement and a cylinder for driving the second-stage support to move transversely are installed on the first-stage support; a third-stage support capable of rotation and a motor for driving the third-stage support to rotate are installed on the second-stage support. The rotation central axis of the third-stage support is horizontally transverse, and the rotation central axis of the third-stage support and the central axis of the winding shaft are in the same horizontal plane and form a perpendicular intersection; the third-stage support is located on the right side of the winding shaft, and a guide wheel, a pressure wheel, a small clamping wheel, and a tape unwinding wheel for placing the adhesive tape roll are installed on the third-stage support. The central axes of the tape unwinding wheel, the guide wheel, the pressure wheel, and the small clamping wheel are parallel to the central axis of the winding shaft. The central axis of the pressure wheel and the rotation central axis of the third-stage support are in the same plane and form a perpendicular intersection. The diameter of the small clamping wheel is smaller than that of the pressure wheel. The small clamping wheel is in contact with the left half side of the pressure wheel, and the left end point of the pressure wheel is more to the left than the left end point of the small clamping wheel.
[0006] Convex points are formed on the surface of the small clamping wheel. Since the contact surface between the convex points and the adhesive tape is small, when the adhesive surface of the adhesive tape runs past the small clamping wheel, it is not easily sticky on the surface of the small clamping wheel.
[0007] A pair of scissors and a scissor driving mechanism for driving the scissors to move longitudinally relative to the first-stage support are also installed on the first-stage support. The transverse position of the scissors is on the right side of the winding shaft.
[0008] A method for automatically winding adhesive tape on a winding shaft, using the above-mentioned apparatus for automatically winding adhesive tape on a winding shaft, successively includes the following steps:
[0009] (1). In the initial state, an adhesive tape roll is placed on the tape unwinding wheel. The longitudinal position of the adhesive tape roll is aligned with the rear end of the winding shaft. The transverse position of the pressure wheel is away from the winding shaft. The small clamping wheel is located above the left of the pressure wheel; the adhesive tape unwound from the adhesive tape roll bypasses the guide wheel and passes between the pressure wheel and the small clamping wheel, then bypasses the left side of the pressure wheel and hangs naturally. The vertical position of the naturally hanging section of the adhesive tape is lower than the central axis of the pressure wheel. The adhesive surface of the naturally hanging section of the adhesive tape faces the winding shaft.
[0010] (2). The cylinder drives the second-stage support to move leftward. The second-stage support drives the motor, the third-stage support, the tape unwinding wheel, the guide wheel, the pressure wheel, the small clamping wheel, and the adhesive tape roll to move leftward synchronously until the pressure wheel presses the adhesive tape against the surface of the winding shaft, causing the adhesive tape to stick to the surface of the winding shaft.
[0011] (3). The winding shaft motor drives the winding shaft to rotate clockwise for more than one circle, so that the adhesive tape is wound around the surface of the rear end of the winding shaft along the circumferential direction of the winding shaft. The adhesive surface of the wound adhesive tape faces the winding shaft and the non-adhesive surface faces away from the winding shaft.
[0012] (4). The air cylinder drives the secondary support to move to the right. The secondary support drives the motor, the tertiary support, the unwinding wheel, the guide wheel, the pressure wheel, the small pinch wheel, and the adhesive tape roll to move to the right synchronously, causing the pressure wheel to leave the winding shaft. During this process, the adhesive tape roll on the unwinding wheel continuously unwinds, and the length of the adhesive tape section between the winding shaft and the pressure wheel continuously increases. The adhesive side of this adhesive tape section faces obliquely upward, and the pressure wheel is located below the adhesive tape.
[0013] (5). The motor drives the tertiary support to rotate 180 degrees, driving the unwinding wheel, the guide wheel, the pressure wheel, the small pinch wheel, and the adhesive tape roll to rotate 180 degrees around the rotation center axis of the tertiary support. The small pinch wheel moves to the lower left of the pressure wheel, and the adhesive tape section near the pressure wheel is twisted 180 degrees with the non - adhesive side facing obliquely upward.
[0014] (6). The winding shaft motor drives the winding shaft to rotate clockwise. At the same time, the lead screw mechanism drives the primary support to move forward. The primary support drives the air cylinder, the secondary support, the motor, the tertiary support, the unwinding wheel, the guide wheel, the pressure wheel, the small pinch wheel, and the adhesive tape roll to move forward synchronously. The adhesive tape roll on the unwinding wheel continuously unwinds, and the surface of the winding shaft is gradually wound with adhesive tape. The wound adhesive tape forms a spiral on the surface of the winding shaft, and the adhesive side of the spiral adhesive tape section faces away from the surface of the winding shaft.
[0015] (7). When the longitudinal position of the adhesive tape roll aligns with the front end of the winding shaft, the lead screw mechanism stops driving the primary support to move, and at the same time, the winding shaft motor stops driving the winding shaft to rotate.
[0016] (8). The motor drives the tertiary support to rotate 180 degrees, and the rotation direction is opposite to that in step (5), driving the unwinding wheel, the guide wheel, the pressure wheel, the small pinch wheel, and the adhesive tape roll to rotate 180 degrees around the rotation center axis of the tertiary support. The small pinch wheel comes back to the upper left of the pressure wheel again, the pressure wheel is located below the adhesive tape again, and the adhesive tape section near the pressure wheel is twisted 180 degrees again with the adhesive side facing obliquely upward.
[0017] (9). The winding shaft motor drives the winding shaft to rotate clockwise for more than one circle, causing the adhesive tape to wind circumferentially along the winding shaft and stick to the front - end surface of the winding shaft.
[0018] (10). Cut the adhesive tape between the winding shaft and the pressure wheel to complete the process of automatically winding the adhesive tape on the winding shaft.
[0019] The present invention has the following advantages and effects:
[0020] First, the present invention can automatically wind the adhesive tape on the surface of the winding shaft in a spiral, saving labor.
[0021] 2. The non - adhesive surface of the helically wound adhesive tape abuts against the take - up reel, and circumferentially extending adhesive tapes are wound around the front and back sides of the helically wound adhesive tape. The adhesive surface of the circumferentially extending adhesive tape abuts against the take - up reel, so that the helically wound adhesive tape can be tightened, and the helically wound adhesive tape can be kept tightly attached to the surface of the take - up reel without generating wrinkles, which is conducive to ensuring the quality of the primer of the coil material.

[0041] Figure 1 and Figure 2 and Figure 3 and Figure 5 A device for automatically winding adhesive tape on a take-up reel as shown includes a frame 15. A take-up reel 10 is placed on the frame 15. The extending direction of the central axis of the take-up reel is longitudinal. There is also a take-up reel motor for driving the take-up reel 10 to rotate. A first-level support 1 capable of longitudinal movement and a lead screw mechanism 11 for driving the first-level support to move longitudinally are also installed on the frame 15. Among them, the lead screw mechanism 11 is equipped with a lead screw motor 14. The first-level support 1 is fixedly connected with a slider 13, and the slider 13 is installed on a longitudinal guide rod 12. A second-level support 2 capable of transverse movement and a cylinder 21 for driving the second-level support to move transversely are installed on the first-level support 1. A third-level support 3 capable of rotation and a motor 31 for driving the third-level support to rotate are installed on the second-level support 2. The rotation central axis of the third-level support 3 (such as Figure 1 and Figure 5 the straight line m in) is horizontally transverse, and the rotation central axis m of this third-level support is in the same horizontal plane as the central axis of the take-up reel ( Figure 1 shown as point A in) and forms a vertical intersection; The third-level support 3 is located on the right side of the take-up reel 10. A guide wheel 5, a pressure wheel 6, a small pinch wheel 7, and a pay-off reel 4 for placing the adhesive tape roll are installed on the third-level support 3. The central axes of the pay-off reel 4, the guide wheel 5, the pressure wheel 6, and the small pinch wheel 7 are parallel to the central axis of the take-up reel. The central axis of the pressure wheel 6 ( Figure 5It is shown as point D in the figure) and the rotation center axis m of the third-level support 3 are in the same plane and form a perpendicular intersection. The diameter of the small pinch wheel 7 is smaller than that of the pressing wheel 6. The small pinch wheel 7 is attached to the left half side of the pressing wheel 6. The left end point of the pressing wheel 6 ( Figure 5 Point B in the figure) is more to the left than the left end point of the small pinch wheel 7 ( Figure 5 Point C in the figure); A scissors 9 and a scissors driving mechanism 91 for driving the scissors to longitudinally move relative to the first-level support 1 are also installed on the first-level support 1. The horizontal position of the scissors 9 is on the right side of the winding shaft 10. Convex points 71 are formed on the surface of the small pinch wheel 7, as shown in Figure 4 shown. Embodiment 2
[0042] A method for automatically winding adhesive tape on a winding shaft, using the equipment for automatically winding adhesive tape on a winding shaft in Embodiment 1, successively includes the following steps:
[0043] (1). In the initial state, an adhesive tape roll 80 is placed on the unwinding wheel 4. The longitudinal position of the adhesive tape roll 80 is aligned with the rear end of the winding shaft 10. The horizontal position of the pressing wheel 6 is away from the winding shaft 10. The small pinch wheel 7 is located above the left side of the pressing wheel 6. The adhesive tape 8 unwound from the adhesive tape roll 80 passes around the guide wheel 5 and passes through between the pressing wheel 6 and the small pinch wheel 7, and then passes around the left side of the pressing wheel 6 and naturally droops. The vertical position of the naturally drooping section of the adhesive tape 8 (such as the EF section in Figure 6 the figure) is lower than the central axis of the pressing wheel 6. The adhesive side 81 of the naturally drooping section of the adhesive tape 8 (such as the EF section in Figure 6 the figure) faces the winding shaft 10, as shown in Figure 6 , Figure 7 , Figure 8 shown (in the relevant top view of the specification drawings, in order to distinguish the adhesive side and the non-adhesive side of the adhesive tape, the adhesive side 81 of the adhesive tape is represented by the shaded part with dots, and the non-adhesive side 82 of the adhesive tape is represented by the shaded part with oblique lines);
[0044] (2). The air cylinder 21 drives the second-level support 2 to move to the left. The second-level support 2 drives the motor 31, the third-level support 3, the unwinding wheel 4, the guide wheel 5, the pressing wheel 6, the small pinch wheel 7, and the adhesive tape roll 80 to move to the left synchronously until the pressing wheel 6 presses the adhesive tape 8 tightly on the surface of the winding shaft 10, so that the adhesive tape 8 adheres to the surface of the winding shaft 10, as shown in Figure 9 , Figure 10 shown;
[0045] (3). The winding shaft motor drives the winding shaft 10 to rotate clockwise for two circles, so that the adhesive tape 8 is wound around the circumferential direction of the winding shaft 10 for two weeks and adheres to the surface of the rear end of the winding shaft. The adhesive side 81 of the adhesivetape wound along the circumferential direction faces the winding shaft and the non-adhesive side 82 faces away from the winding shaft, as shown in Figure 11 shown;
[0046] (4). The cylinder 21 drives the secondary support 2 to move rightward. The secondary support 2 drives the motor 31, the tertiary support 3, the unwinding wheel 4, the guide wheel 5, the pressure wheel 6, and the small clamping wheel 7 to move rightward synchronously, causing the pressure wheel 6 to leave the winding shaft 10. During this process, the adhesive tape roll 80 on the unwinding wheel 4 continues to unwind continuously, and the length of the adhesive tape section between the winding shaft 10 and the pressure wheel 6 increases continuously. The adhesive tape surface 81 of this adhesive tape section faces obliquely upward, and the pressure wheel 6 is located below the adhesive tape, as Figure 12 、 Figure 13 shown;
[0047] (5). The motor 31 drives the tertiary support 3 to rotate 180 degrees, driving the unwinding wheel 4, the guide wheel 5, the pressure wheel 6, the small clamping wheel 7, and the adhesive tape roll 80 to rotate 180 degrees around the rotation center axis m of the tertiary support. The small clamping wheel 7 moves to the lower left of the pressure wheel 6, and the adhesive tape section close to the pressure wheel 6 is twisted 180 degrees so that the non - adhesive surface 82 faces obliquely upward, as Figure 14 、 Figure 15 shown;
[0048] (6). The winding shaft motor drives the winding shaft 10 to rotate clockwise. At the same time, the lead screw mechanism 11 drives the primary support 1 to move forward. The primary support 1 drives the secondary support 2, the cylinder 21, the motor 31, the tertiary support 3, the unwinding wheel 4, the guide wheel 5, the pressure wheel 6, the small clamping wheel 7, the adhesive tape roll 80, the scissors 9, and the scissors driving mechanism 91 to move forward synchronously. The adhesive tape roll 80 on the unwinding wheel 4 unwinds continuously, and the surface of the winding shaft 10 is gradually wound with the adhesive tape 8. The wound adhesive tape 8 forms a spiral on the surface of the winding shaft 10, and the adhesive tape surface 81 of the spiral adhesive tape section faces away from the surface of the winding shaft 10, as Figure 16 、 Figure 17 shown;
[0049] (7). When the longitudinal position of the adhesive tape roll 80 aligns with the front end of the winding shaft 10, the lead screw mechanism 11 stops driving the primary support 1 to move, and at the same time, the winding shaft motor stops driving the winding shaft 10 to rotate;
[0050] (8). The motor 31 drives the tertiary support 3 to rotate 180 degrees again, and the rotation direction is opposite to that in step (5). The tertiary support 3 drives the unwinding wheel 4, the guide wheel 5, the pressure wheel 6, the small clamping wheel 7, and the adhesive tape roll 80 to rotate 180 degrees around the rotation center axis m of the tertiary support. The small clamping wheel 7 returns to the upper left of the pressure wheel 6 again, the pressure wheel 6 is again located below the adhesive tape 8, and the adhesive tape 8 section close to the pressure wheel 6 is twisted 180 degrees again so that the adhesive tape surface 81 faces obliquely upward, as Figure 18 shown;
[0051] (9). The winding shaft motor drives the winding shaft 10 to rotate clockwise for two circles, causing the adhesive tape 8 to wind two circles along the circumferential direction of the winding shaft and stick to the front - end surface of the winding shaft, as Figure 19 shown;
[0052] (10). The scissor drive mechanism 91 drives the scissors 9 to move forward to cut the adhesive tape 8 located between the winding shaft 10 and the pressure wheel 6. After that, the scissor drive mechanism 91 drives the scissors 9 to move backward and reset. The lead screw mechanism 11 drives the first-stage support 1 to move backward. The first-stage support 1 drives the second-stage support 2, the cylinder 21, the motor 31, the third-stage support 3, the unwinding wheel 4, the guide wheel 5, the pressure wheel 6, the small clamping wheel 7, the adhesive tape roll 80, the scissors 9, and the scissor drive mechanism 91 to move backward and reset synchronously. In this way, the process of automatically winding the adhesive tape on the winding shaft is completed. The obtained winding shaft is tightly and densely wound with a spiral adhesive tape between the front and rear ends, and the spiral adhesive tape will not produce wrinkles. The adhesive side of the spiral adhesive tape faces outward. The adhesive tape in this section can be used for the bottom layer of the film roll.
