All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, 2, 4 and 5, the rewinding machine of the present invention comprises a reel-up 11, a taping and cutting assembly 12. In which the reel assembly 11 comprises a reel drum 111, the reel drum 111 being rotated so that its surface receives the web 101 to be rewound. The tape attaching and cutting assembly 12 is capable of moving in the width direction of the paper tape 101 with respect to the paper roll 111 and attaching the tape 181 to the paper tape 101 received by the paper roll 111, and cuts the tape 181 and the paper tape 101 in the attaching direction of the tape 181 to form a tail 1012 for closing a finished roll and a head 1011 for fixing to the paper core tube 102.
In the present embodiment, web 101 to be rewound refers to web 101 to be wound into a finished roll. In the manufacturing process of the finished roll, the paper core tube 102 continuously winds the paper tape 101 to be rewound on the surface of the paper winding cylinder 111 through the head 1011 adhered to the paper core tube 102 or actively or passively, when the paper tape amount wound by the paper core tube 102 meets the requirement of the finished roll, the tape adhering and cutting assembly 12 can move along the width direction of the paper tape 101 relative to the paper winding cylinder 111, adhere the tape 181 to the paper tape 101, and simultaneously cut the tape 181 and the paper tape 101 along the adhering direction of the paper tape 101, wherein one part of the tape 181 is adhered to the tail 1012 to seal the finished roll, the other part of the tape 181 is adhered to the head 1011, and the tape 181 is adhered to the paper core tube 102 to start manufacturing a new finished roll.
Through the tape adhering and cutting assembly 12, the tape 181 is moved in the width direction of the paper tape 101 relative to the paper winding cylinder 111 and is adhered to the paper tape 101 received by the paper winding cylinder 111, and the tape 181 and the paper tape 101 are cut in the adhering direction of the tape 181, so that the adhering of the tape 181 can be automatically realized, and the tape 181 and the paper tape 101 can be automatically cut.
With reference to fig. 1 and fig. 2, optionally, the interior of the paper winding cylinder 111 is hollow, the paper winding assembly 11 further includes a vacuum extractor 112, the surface of the paper winding cylinder 111 is formed with an air hole 1111, the air hole 1111 is communicated with the interior of the paper winding cylinder 111, and the vacuum extractor 112 is configured to extract air inside the paper winding cylinder 111, so that the paper tape 101 adheres to the surface of the paper winding cylinder 111 under the effect of the pressure difference between the inside and the outside of the air hole 1111.
Referring to fig. 1-6, optionally, before the tape 181 is adhered by the tape adhering and cutting assembly 12 or after the tape 181 and the tape 101 are cut, the paper winding cylinder 111 rotates the air holes 1111 to the lower side of the tail 1012 or the head 1011, so that the tail 1012 or the head 1011 adheres to the surface of the paper winding cylinder 111 by the air holes 1111 under the tail 1012 or the head 1011.
With continued reference to fig. 6, in the present embodiment, before the tape 181 is adhered by the tape adhering and cutting assembly 12 or after the tape 181 and the paper tape 101 are cut, the paper winding cylinder 111 rotates the air holes 1111 to the paper tail 1012 (including the paper tail 1012 to be cut), and the paper tape 101 adheres to the surface of the paper winding cylinder 111 under the difference between the internal air pressure and the external air pressure of the air holes 1111 under the action of the vacuum pumping device 112. After the adhesive tape 181 and the paper tape 101 are cut, the paper tail 1012 can be stably attached to the surface of the paper winding cylinder 111 due to the adsorption effect of the air pressure difference along with the rotation of the paper winding cylinder 111 so as to smoothly seal the tail of the finished roll, and finally the finished roll is formed, so that the problems that after the paper tape 101 is cut, the paper tail 1012 falls due to no attaching force, paper jam or damage to the paper tail 1012 is caused can be solved.
Similarly, before the tape 181 is adhered to the tape adhering and cutting assembly 12 or after the tape 181 and the paper tape 101 are cut, the air hole 1111 is rotated to the paper head 1011 by the paper winding cylinder 111, so that after the tape 181 and the paper tape 101 are cut, along with the rotation of the paper winding cylinder 111, the paper head 1011 can be stably adhered to the surface of the paper winding cylinder 111 due to the adsorption effect of the air pressure difference of the air hole 1111, so as to be smoothly and stably adhered to the surface of the paper winding cylinder 111, and the paper tape 101 is restarted for forming a finished product roll, thereby solving the problems that after the paper tape 101 is cut, the paper head 1011 drops due to no adhesion force, so that paper jam or damage to the paper head 1011 is caused, and the paper head 1011 cannot be smoothly adhered to the paper core tube 102 so that paper.
Of course, the paper tube 111 rotates the air holes 1111 to the lower side of the paper tail 1012 and the paper head 1011, that is, the paper tube 111 rotates at least two air holes 1111 adjacently arranged to the lower side of the paper tail 1012 and the paper head 1011, and the paper head 1011 and the paper tail 1012 correspond to at least one air hole 1111 respectively. Referring to fig. 6, for example, before the tape 181 is adhered to the tape adhering and cutting assembly 12 or after the tape 181 and the paper tape 101 are cut, the paper winding cylinder 111 rotates at least two air holes 1111 disposed adjacently to the lower side of the paper tail 1012 and the paper head 1011, the paper tail 1012 seals the end of the finished roll of the paper core 102 along with the rotation of the paper winding cylinder 111 and the rotation of the paper core 102 under the absorption of the air holes 1111, after the end of the finished roll is sealed, the paper winding cylinder 111 rotates at least two air holes 1111 of the group or other groups of air holes 1111 to the lower side of the paper head 1011, then the paper head 1012 rotates to the paper core 102 along with the rotation of the paper winding cylinder 111 and contacts the paper core 102, so that the tape 181 on the paper head 1011 adheres to the paper core 102, and the paper tape 102 is wound to make the finished roll, and the process is repeated. Therefore, the tape and the paper tape can be automatically pasted and cut by the rewinding machine, so that the paper tape can be automatically coiled, and the production efficiency is improved.
With continued reference to fig. 1 and fig. 2, optionally, a plurality of sets of air holes 1111 are formed on the surface of the paper winding cylinder 111 at intervals along the circumferential direction, and each set of air holes 1111 are arranged at intervals along the axial direction of the paper winding cylinder 111.
For example, when viewed from a cross section of the paper winding cylinder 111 perpendicular to the axis, a plurality of sets of air holes 1111, for example, 5 sets of air holes 1111, are formed at intervals in the circumferential direction on the surface of the paper winding cylinder 111, and are uniformly or non-uniformly formed in the circumferential direction on the surface of the paper winding cylinder 111. Also, the number of air holes 1111 in each set is visible as one or two on a cross-sectional circumference, although it could be more than two. For example, when the number of air holes 1111 in each set is two, the two air holes 1111 may be disposed adjacent to each other, and the winding cylinder 111 rotates the two air holes 1111 to the lower side of the tail 1012 and the head 1011 corresponding to the tail 1012 and the head 1011, respectively, before the tape 181 is adhered or after the tape 181 and the tape 101 are cut by the tape adhering and cutting assembly 12. For example, when the number of air holes 1111 in each set is one, before the tape 181 is adhered to the tape adhering and cutting assembly 12 or after the tape 181 and the paper tape 101 are cut, the paper winding tube 111 rotates one set of air holes 1111 under the paper tail 1012 to seal the end of the finished roll, and then rotates the other set of air holes 1111 under the paper head 1011 to adhere the paper head 1011 to the paper core tube 102. Of course, the number of air holes 1111 in each set is not necessarily the same, but may be different, and may be set according to actual situations. Each set of the air holes 1111 is spaced along the axial direction of the paper winding cylinder 111, for example, each set of the air holes is 10, and the number of the air holes in the circumferential direction is one, so that the 10 air holes are arranged on the surface of the paper winding cylinder 111 at equal or unequal intervals along the axial direction, or arranged in the axial direction.
In other embodiments, the paper tape 101 may be attached to the surface of the paper winding cylinder 111 by electrostatic interaction, for example, by generating static electricity on the surface of the paper winding cylinder 111 by an electrostatic attachment generator, so that the paper tape 101 is attached to the paper winding cylinder 111 by different charges. Of course, it is also possible to fix the paper tape 101 by the magnetic force of the magnet and the roll paper tube 111 by applying a pressure such as a magnetic force from the outside.
In other embodiments, the air holes 1111 may be elongated holes, the extending direction of the holes may be parallel to the axis, or may form a certain angle with the axis, wherein the length of the elongated holes is not limited herein, for example, the elongated holes may be axially spaced apart, or may be spirally formed on the surface of the winding cylinder 111.
With continued reference to fig. 1 and 2, the roll assembly 11 optionally further includes a nip 113, a guide roll 114, and a platen roll 115. The guide roller 114 is disposed opposite to the sheet holder 113, and the sheet 101 is guided by the guide roller 114 and fed into the roll paper 111. The platen roller 115 is used for pressing the paper tape 101 received by the paper winding cylinder 111 against the surface of the paper winding cylinder 111 so as to drive the paper tape 101 to move by the rotation of the paper winding cylinder 111. Wherein the roll paper tube 111 stops rotating before the tape applying and cutting assembly 12 applies the tape 181, the pinch frame 113 moves toward the guide roller 114 to pinch the paper tape 101, and the platen roller 115 is separated from the roll paper tube 111.
Before the tape 181 is applied by the tape applying and cutting assembly 12, the paper clamping frame 113 and the guide roller 114 cooperate with each other to press the paper tape 101, so that the paper tape 101 maintains tension, a new winding action of the paper tape 101 after the applying and cutting is facilitated, the occurrence of paper jam or paper winding irregularity caused by the slackening of the paper tape 101 is avoided, and the paper pressing roller 115 presses the paper tape 101 on the surface of the paper winding cylinder 111 after the applying and cutting is completed, so that the paper tape 101 can effectively rotate along with the rotation of the paper winding cylinder 111, and the tension of the paper tape 101 is maintained, so as to wind the paper tape 101. In a specific operation, a guide roller that guides the paper tape 101 to be fed to the surface of the paper roll 111 and a platen roller 115 that presses the paper tape 101 on the surface of the paper roll 111 are capable of rolling along with the movement of the paper tape 101, so that the paper tape 101 can be smoothly transferred to the paper roll 111 and wound. In the present embodiment, the platen roller 115 may be lifted or pressed down by a driving mechanism such as an air cylinder or a driving motor.
With continued reference to fig. 1, 2, 5, and 6, optionally, the paper roll 111 stops rotating after the air hole 1111 has been rotated to a position below the paper tail 1012 before the tape application and cutting assembly 12 applies the tape 181. After the tape adhering and cutting assembly 12 cuts the tape 181 and the paper tape 101, the paper clamping frame 113 and the guide roller 114 are kept in a clamping state, and the paper pressing roller 115 and the paper winding cylinder 111 are kept in a separation state, so that the paper winding cylinder 111 drives the paper tail 1012 to move under the condition that the paper head 1011 is not moved, and the tail sealing of the paper tail 1012 to the finished roll is realized. The roll paper tube 111 stops rotating, facilitating the adhesive tape 181 to be pasted and the adhesive tape 181 to be cut and the paper tape 101.
The paper winding cylinder 111 further rotates the air hole 1111 to the lower side of the paper head 1011, the paper clamping frame 113 is separated from the guide roller 114, and the paper pressing roller 115 presses the paper tape 101 on the surface of the paper winding cylinder 111, so that the paper winding cylinder 111 drives the paper head 1011 to move, and further the fixation of the paper head 1011 on the paper core tube 102 and the winding of the paper tape 101 on the paper core tube 102 are realized.
For example, in this embodiment, the control system (not shown) such as a PLC control system may control the paper winding cylinder 111 and the tape adhering and cutting assembly 12, before the tape 181 is adhered, the control system controls the paper winding cylinder 111 to rotate the air hole 1111 to a position below the tail 1012 and then stop rotating, the vacuum extractor 112 adsorbs and fixes the tail 1012, and after the control system controls the tape adhering and cutting assembly 12 to cut the paper tape 101, the tail 1012 is ensured not to fall off, thereby ensuring the smooth sealing of the tail of the finished roll. Before the control system controls the tape attaching and cutting assembly 12 to attach the tape 181 or after the tape 101 and the tape 181 are cut, the control system controls the paper winding cylinder 111 to rotate the air hole 1111 to the lower side of the paper head 1011, the paper clamping frame 113 is separated from the guide roller 114, and the paper pressing roller 115 presses the tape 101 on the surface of the paper winding cylinder 111, so as to ensure that the tape 101 moves smoothly along with the rotation of the paper winding cylinder 111.
Referring to fig. 1-5, in which fig. 4 shows the unwound tape roll 18, the tape application and cutting assembly 12 may optionally include a tape unwinding reel 121, a tape winding reel 122, a motor 123, an application rotator 124, and an application driver 125. The tape unwinding reel 121 is used for placing the tape roll 18 and unwinding the tape roll 18, wherein the tape roll 18 is formed by winding a tape 181 and a liner 182 for carrying the tape 181. The tape winding reel 122 is used to wind the liner tape 182 after the tape 181 is stuck to the paper tape 101. The motor 123 is used for driving the tape winding disc 122 to rotate, and the lining tape 182 drives the unwinding disc to rotate for unwinding. The adhesive rotating member 124 is disposed between the tape unwinding reel 121 and the tape receiving reel 181, wherein the tape 181 unwound from the tape unwinding reel 121 and the liner tape 182 pass through the adhesive rotating member 124. The paste driving member 125 is used to drive the paste rotor 124 together with the adhesive tape 181 and the liner tape 182 to approach and separate from the roll paper cylinder 111, and to bring the adhesive tape 181 into contact with the paper tape 101 on the roll paper cylinder 111 when approaching the roll paper cylinder 111, thereby causing the adhesive tape 181 to paste on the paper tape 101. The cutter 126 is located on the side of the adhering and rotating member 124 close to the tape winding reel 122, and cuts the tape 101 and the adhesive tape 181 after the adhesive tape 181 is adhered to the tape 101.
Under the action of the motor 123, the tape winding disc 122 rotates to drive the tape winding disc 122 to rotate, the tape roll 18 is unwound and released from the tape unwinding disc 121, the tape 181 of the tape roll 18 is adhered to the tape 101 by the action of the adhesion rotating member 124 and the adhesion driving member 125, and the liner tape 182 is fed into the tape winding disc 122. Where adhesive rotator 124 is, for example, an adhesive roller, tape 181 faces tape 101 and liner 182 directly contacts adhesive roller as tape roll 18 passes over the adhesive roller. The adhesion driving unit 125 is a driving mechanism such as an air cylinder, and the air cylinder moves, for example, to move the adhesion roller closer to or away from the paper roll 111 and to adhere the adhesive tape 181 to the paper tape 101 when the adhesion roller approaches. The cutter 126 is generally positioned behind the adhering rotor 124 in the direction in which the taping and cutting assembly 12 moves, so as to cut the tape 181 and the tape 101 after the tape 181 is adhered to the tape 101. Through the mode, the automatic pasting and cutting of the adhesive tape 181 can be realized, so that the paper rolling efficiency is improved, the labor is saved, and meanwhile, the problems of high error rate, low yield and the like caused by manual operation are solved.
Referring to fig. 5, at least two paper tapes 101 are alternatively provided along the axial direction of the roll paper cylinder 111 at intervals, wherein the paste driving member 125 drives the paste rotating member 124 to approach and separate from the roll paper cylinder 111 according to the widths of the at least two paper tapes 101, so that the adhesive tape 181 is pasted on only the at least two paper tapes 101.
For example, when the preceding tape 101 is to be pasted, the pasting driver 125 is a driving mechanism such as an air cylinder, and the pasting rotor 124 is brought close to the winding cylinder 111, and the tape 181 is pasted to the preceding tape 101. After the first tape 101 is pasted, the pasting driving member 125 moves the pasting rotation member 124 away from the winding cylinder 111, and when the pasting rotation member 124 moves to the second tape 101, the pasting rotation member 124 is moved closer to the winding cylinder 111 again, and the tape 181 is pasted on the second tape 101. In this embodiment, the cutting blade 126 may be moved toward and away from the roll paper tube 111 together with the paste rotating member 124, or may be kept in the cutting operation at all times. In the present embodiment, the tape adhering and cutting assembly 12 is controlled by the control system to adhere according to the width of the paper tape 101, for example, the width of the paper tape 101 is stored in the control system, and the control system transmits the width of the paper tape 101 to the tape adhering and cutting assembly 12. The tape attaching and cutting assembly 12 attaches the paper tape 101 according to the width of the paper tape 101, so that the paper tape 101 can be wound at the same time, a plurality of finished product rolls can be manufactured at the same time, the manufacturing efficiency is improved, the automation is realized, and the production cost is reduced. Generally, the paper tape 101 on the roll paper cylinder 111 has a uniform width so as to be uniformly wound and manufactured, but the width of the paper tape 101 may be different and may be designed according to actual conditions.
