Description

Technical Field

[0001] The invention belongs to the technical field of winding, and in particular relates to a device and a method for automatically winding adhesive tape around a winding shaft. Background Art

[0002] The film is wound up using a reel to form a film roll. Based on the destination of the film roll, the film roll can be divided into two categories. The first category is sold as a finished product to the market; the second category is sold as a semi-finished product to other workshops in the factory for reprocessing, and the reprocessing process requires gradual unwinding. Before the first type of film roll is wound up, a paper core tube needs to be put on the outside of the reel. After winding up, the reel is pulled out of the paper core tube, and the paper core tube and the film roll are sold to the market. The above-mentioned reel needs to be an air-expansion shaft so that the paper core tube can be tightened during the winding process and pulled out after winding up; while the second type of film roll can omit the paper core tube, that is, the film is directly wound up by a metal reel, which not only saves paper core tubes, but also does not need to use an air-expansion shaft, and an ordinary reel can be used for winding. Of course, before the second type of film roll is rolled up, it is necessary to wrap adhesive tape around the surface of the winding shaft. The wrapped adhesive tape is in a spiral shape, and the non-adhesive side of the adhesive tape (i.e. the side not coated with adhesive) is against the surface of the winding shaft, while the adhesive side of the adhesive tape (i.e. the side coated with adhesive) is facing away from the surface of the winding shaft, so that the film can be stuck to the surface of the winding shaft.

[0003] The process of wrapping the adhesive tape around the reel of the traditional second-class film roll is done manually. The adhesive tape is not easy to stick densely and tightly to the surface of the reel, and it is easy to loosen and wrinkle, affecting the quality of the film roll base. In addition, when the reel is long, it is more labor-consuming and time-consuming, 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 disadvantages and provide a device and method for automatically winding adhesive tape around a reel, which can automatically wind the adhesive tape around the surface of the reel and make the adhesive tape tightly adhere to the surface of the reel without generating wrinkles.

[0005] The present invention can be implemented according to the following scheme: a device for automatically winding adhesive tape with a reel, comprising a frame, a reel placed on the frame, the central axis of the reel extending in the longitudinal direction, and a reel motor driving the reel to rotate; its main features are that the frame is also equipped with a primary support capable of longitudinal movement and a screw mechanism driving the primary support to move longitudinally; the primary support is equipped with a secondary support capable of transverse movement and a cylinder driving the secondary support to move transversely; the secondary support is equipped with a rotatable tertiary support and a motor driving the tertiary support to rotate, the rotation central axis of the tertiary support is horizontal The three-stage support is horizontally flat, and the rotation center axis of the three-stage support is in the same horizontal plane with the center axis of the winding shaft to form a vertical intersection; the three-stage support is located on the right side of the winding shaft, and the three-stage support is equipped with a guide wheel, a pressure wheel, a small clamping wheel, and a reeling wheel for placing the adhesive tape roll. The center axes of the reeling wheel, the guide wheel, the pressure wheel and the small clamping wheel are parallel to the center axis of the winding shaft, the center axis of the pressure wheel and the rotation center axis of the three-stage support are in the same plane to form a vertical intersection, the diameter of the small clamping wheel is smaller than the diameter of the pressure wheel, the small clamping wheel is close to the left half of the pressure wheel, and the left end point of the pressure wheel is further to the left than the left end point of the small clamping wheel.

[0006] The surface of the small clamping wheel is formed with convex points. Since the contact surface between the convex points and the adhesive tape is small, the adhesive surface of the adhesive tape is not easy to stick to the surface of the small clamping wheel when it passes through the small clamping wheel.

[0007] The primary support is also provided with scissors and a scissor driving mechanism for driving the scissors to move longitudinally relative to the primary support, and the scissors are located at the right side of the winding shaft in the transverse position.

[0008] A method for automatically winding adhesive tape around a reel, using the above-mentioned automatic adhesive tape winding device around a reel, comprises the following steps in sequence: (1). In the initial state, a roll of adhesive paper is placed on the unwinding wheel, the longitudinal position of the roll of adhesive paper is aligned with the rear end of the winding shaft, the lateral position of the pressure wheel is away from the winding shaft, and the small clamping wheel is located at the upper left of the pressure wheel; after the roll of adhesive paper is unwound, the adhesive paper output 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 droops naturally, the vertical position of the naturally drooping section of the adhesive paper is lower than the central axis of the pressure wheel, and the adhesive surface of the naturally drooping section of the adhesive paper faces the winding shaft; (2) The cylinder drives the secondary support to move to the left, and the secondary support drives the motor, the tertiary support, the unwinding wheel, the guide wheel, the pressure wheel, the small clamping wheel, and the adhesive tape roll to move to the left synchronously until the pressure wheel presses the adhesive tape against the surface of the take-up shaft, so that the adhesive tape adheres to the surface of the take-up shaft; (3) The motor of the reel drives the reel to rotate clockwise for more than one circle, so that the adhesive paper is wound around the reel to the surface of the rear end of the reel, with the adhesive surface of the wound adhesive paper facing the reel and the non-adhesive surface facing away from the reel; (4) The cylinder drives the secondary support to move to the right, and the secondary support drives the motor, the tertiary support, the unwinding wheel, the guide wheel, the pressure wheel, the small clamping wheel, and the adhesive tape roll to move to the right synchronously, so that the pressure wheel leaves the reel; during this process, the adhesive tape roll on the unwinding wheel is continuously unwound, and the length of the adhesive tape section between the reel and the pressure wheel is continuously increased. The adhesive surface of the adhesive tape section faces obliquely upward, and the pressure wheel is located below the adhesive tape; (5) The motor drives the three-stage support to rotate 180 degrees, driving the unwinding wheel, guide wheel, pressure wheel, small clamping wheel, and adhesive tape winding three-stage support to rotate 180 degrees. The small clamping wheel moves to the lower left of the pressure wheel, and the adhesive tape section close to the pressure wheel is twisted 180 degrees with the non-adhesive surface facing diagonally upwards; (6) The motor of the reel drives the reel to rotate clockwise, and at the same time, the screw mechanism drives the primary support to move forward. The primary support drives the cylinder, the secondary support, the motor, the tertiary support, the unwinding wheel, the guide wheel, the pressure wheel, the small clamping wheel, and the adhesive roll to move forward synchronously. The adhesive roll on the unwinding wheel is continuously unwound, and the surface of the reel is gradually wound with adhesive paper. The wound adhesive paper forms a spiral on the surface of the reel, and the adhesive surface of the spiral adhesive paper section faces away from the surface of the reel; (7) When the longitudinal position of the adhesive tape roll is aligned with the front end of the reel, the screw mechanism stops driving the primary support to move, and the reel motor stops driving the reel to rotate; (8) The motor drives the three-stage support to rotate 180 degrees, and the rotation direction is opposite to the rotation direction of step (5), driving the unwinding wheel, guide wheel, pressure wheel, small clamping wheel, and adhesive tape winding three-stage support to rotate 180 degrees. The small clamping wheel returns to the upper left of the pressure wheel, and the pressure wheel is again located under the adhesive tape. The adhesive tape section close to the pressure wheel is twisted 180 degrees again and the adhesive surface faces obliquely upward; (9) The motor of the reel drives the reel to rotate clockwise for more than one circle, so that the adhesive tape is wound around the circumference of the reel and adhered to the front end surface of the reel; (10) Cut off the adhesive tape between the take-up reel and the pressure wheel to complete the process of automatically winding the adhesive tape around the take-up reel.

[0009] The present invention has the following advantages and effects: 1. The present invention can automatically spirally wind adhesive tape on the surface of the reel, saving labor; 2. The non-adhesive surface of the spirally wound adhesive tape is against the reel, and the front and rear sides of the spirally wound adhesive tape are also wound with circumferentially extending adhesive tape, and the adhesive surface of the circumferentially extending adhesive tape is against the reel, so that the spirally wound adhesive tape can be tightened and kept tightly against the surface of the reel without wrinkles, which is conducive to ensuring the base quality of the coil.

[0030] A method for automatically winding adhesive tape around a reel, using the device for automatically winding adhesive tape around a reel of the first embodiment, comprises the following steps in sequence: (1) In the initial state, the unwinding wheel 4 is provided with a rubber roll 80, the longitudinal position of the rubber roll 80 is aligned with the rear end of the winding shaft 10, the lateral position of the pressing wheel 6 is away from the winding shaft 10, and the small clamping wheel 7 is located at the upper left of the pressing wheel 6; after the rubber roll 80 is unwound, the rubber roll 8 passes around the guide wheel 5 and passes between the pressing wheel 6 and the small clamping wheel 7, then passes around the left side of the pressing wheel 6 and droops naturally, and the rubber roll 8 droops naturally (such as Figure 6 The vertical position of the EF section is lower than the central axis of the pressing wheel 6, and the adhesive tape 8 naturally droops (such as Figure 6 The adhesive surface 81 of the tape 81 in the paragraphs EF) faces the reel 10, as shown in FIG. Figure 6 , Figure 7 , Figure 8 As shown (in the top view of the accompanying drawings of the specification, in order to distinguish the adhesive surface of the adhesive tape from the non-adhesive surface, the adhesive surface 81 of the adhesive tape is represented by a dotted shaded area, and the non-adhesive surface 82 of the adhesive tape is represented by a slashed shaded area); (2) The cylinder 21 drives the secondary support 2 to move to the left, and the secondary support 2 drives the motor 31, the tertiary support 3, the unwinding wheel 4, the guide wheel 5, the pressure wheel 6, the small clamping wheel 7, and the adhesive roll 80 to move to the left synchronously until the pressure wheel 6 presses the adhesive paper 8 against the surface of the winding shaft 10, so that the adhesive paper 8 adheres to the surface of the winding shaft 10. Fig. 9 , Fig.10 As shown; (3) The motor of the reel drives the reel 10 to rotate two circles clockwise, so that the adhesive tape 8 is wound around the reel 10 for two circles and adhered to the surface of the rear end of the reel. The adhesive surface 81 of the adhesive tape wound around the reel faces the reel and the non-adhesive surface 82 faces away from the reel. Fig.11 As shown; (4) The cylinder 21 drives the secondary support 2 to move rightward, and 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, so that the pressure wheel 6 leaves the reel 10; during this process, the adhesive tape roll 80 on the unwinding wheel 4 continues to be unwound, and the length of the adhesive tape section between the reel 10 and the pressure wheel 6 continues to increase. The adhesive surface 81 of the adhesive tape section faces obliquely upward, and the pressure wheel 6 is located below the adhesive tape. Fig.12 , Fig.13 As shown; (5) The motor 31 drives the three-stage 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 roll 80 to rotate 180 degrees around the rotation center axis m of the three-stage support. The small clamping wheel 7 moves to the lower left of the pressure wheel 6. The adhesive section close to the pressure wheel 6 is twisted 180 degrees and the non-adhesive surface 82 faces obliquely upward, such as Fig.14 , Fig.15 As shown; (6) The motor of the reel drives the reel 10 to rotate clockwise, and at the same time, the 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 roll 80, the scissors 9, and the scissors driving mechanism 91 to move forward synchronously. The adhesive roll 80 on the unwinding wheel 4 is continuously unwound, and the adhesive paper 8 is gradually wound on the surface of the reel 10. The wound adhesive paper 8 forms a spiral on the surface of the reel 10, and the adhesive surface 81 of the spiral adhesive paper section faces away from the surface of the reel 10, as shown in FIG. Fig.16 , Fig.17 As shown; (7). When the longitudinal position of the adhesive tape roll 80 is aligned with the front end of the reel 10, the screw mechanism 11 stops driving the primary support 1 to move, and the reel motor stops driving the reel 10 to rotate; (8) The motor 31 drives the three-stage support 3 to rotate 180 degrees again, and the rotation direction is opposite to the rotation direction of step (5). The three-stage 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 three-stage support. The small clamping wheel 7 returns to the upper left of the pressure wheel 6, and the pressure wheel 6 is again located below the adhesive tape 8. The section of the adhesive tape 8 close to the pressure wheel 6 is twisted 180 degrees again and the adhesive surface 81 faces obliquely upward, as shown in FIG. Fig.18 As shown; (9) The motor of the reel drives the reel 10 to rotate two circles clockwise, so that the adhesive tape 8 is wound around the reel twice and adhered to the front end surface of the reel. Fig.19 As shown; (10). The scissor drive mechanism 91 drives the scissors 9 to move forward and cut the adhesive tape 8 between the reel 10 and the pressure wheel 6. Then, the scissor drive mechanism 91 drives the scissors 9 to move backward and reset. The screw mechanism 11 drives the primary support 1 to move backward. 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 scissor drive mechanism 91 to move backward and reset synchronously. In this way, the process of automatically winding the adhesive tape on the reel is completed. The section between the front and rear ends of the reel is tightly and densely wound with spiral adhesive tape, and the spiral adhesive tape will not produce wrinkles. The adhesive surface of the spiral adhesive tape faces outward. The adhesive tape in this section can be used as a base for the film roll.
