[0001] The invention relates to the field of adhesive tape winding, and in particular to an automatic reel replacement device and an adhesive tape winding machine. Background Art

[0002] During the production process of tape, the production of tape is mainly completed through processes such as gluing, striping and winding. After the gluing process, a large-sized tape roll is obtained. The tape on the tape roll is led to the winding station through several rollers for winding. During the tape transmission process, the tape is cut along the width direction. The cut tape strips are wound up to obtain multiple independent tape rolls.

[0003] The last step in the tape production process is tape winding, which is generally done using a reel on a winder.

[0004] The roll that has completed tape winding will be replaced, and the roll will be taken out manually for unloading, and a new roll will be reinstalled to replace the roll after the current roll winding work is completed. Both loading and unloading are done manually, and the next winding cycle is started manually after unloading and loading are completed. The entire tape winding process is affected by manual factors, and it may take a long time to start the next winding cycle after a single winding cycle is completed. The tape winding efficiency cannot be guaranteed. Summary of the invention

[0006] In order to solve the above technical problems, the present invention specifically provides the following technical solutions: an automatic reel replacement device, comprising two locking plate groups arranged relatively parallel to each other, and the two ends of the reel are respectively arranged on one of the locking plate groups;

[0007] The locking plate assembly includes a first disassembly plate and a second disassembly plate, a cavity for assembling the end of the reel is formed between the first disassembly plate and the second disassembly plate, and the relative position between the first disassembly plate and the second disassembly plate is adjustable, so that the cavity is locked when the first disassembly plate and the second disassembly plate are relatively close to each other, and is unlocked when they are relatively far away from each other;

[0008] A side inlet is formed on the upper side of the cavity, and a side outlet is formed on the lower side of the cavity. The side inlet and the side outlet are expanded when the first disassembly plate and the second disassembly plate are relatively far apart, so that the end of the roll in the cavity can fall through the side outlet, and the end of the roll to be loaded can enter the cavity through the side inlet;

[0011] The side inlet is directly opposite to the feeding guide rail, and the side outlet is relatively far away from the directly opposite position of the side inlet;

[0012] Wherein, the minimum width of the side inlet and the side outlet is smaller than the width of the prism axis.

[0028] Furthermore, a strong magnetic block is installed on the inner side wall of the second disassembly and assembly plate;

[0029] The strong magnetic block can generate magnetic attraction force on the prism axis in the cavity. The strong magnetic block moves synchronously when the second disassembly plate moves away from the first disassembly plate and drives the prism axis to move toward the opposite position close to the side outlet under the action of the magnetic attraction force until the prism axis can directly pass through the side outlet to discharge the material.

[0063] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0064] like Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the present invention provides an automatic reel replacement device, comprising two locking plate groups 6 arranged relatively parallel to each other, and two ends of the reel 2 are respectively arranged on a locking plate group 6.

[0065] Reel 2 is used for winding the tape and can be set to 1, 2, 3, ..., depending on the actual situation. At the current time, there is usually only one reel 2 that is winding. After the winding is completed, the reel 2 is disassembled and replaced. The design of the locking plate group 6 can realize the free replacement and installation of the shaft end of the reel 2.

[0066] In order to realize full automation, a cutting blade can be arranged on the upper side of the reel 2, and the cutting blade can be raised and lowered to cut the adhesive tape 17 between the reels 2. After cutting, the unloading and loading of the reels can be carried out.

[0067] The locking plate group 6 includes a first disassembly plate 61 and a second disassembly plate 62. A cavity 12 for assembling the end of the reel is formed between the first disassembly plate 61 and the second disassembly plate 62. The relative position between the first disassembly plate 61 and the second disassembly plate 62 is adjustable, so that the cavity 12 is locked when the first disassembly plate 61 and the second disassembly plate 62 are relatively close, and unlocked when they are relatively far away.

[0068] A side inlet 7 is formed on the upper side of the cavity 12, and a side outlet 11 is formed on the lower side of the cavity 12. The side inlet 7 and the side outlet 11 expand when the first disassembly plate 61 and the second disassembly plate 62 are relatively far apart, so that the end of the roll in the cavity 12 can fall through the side outlet 11, and the end of the roll 2 to be loaded can enter the cavity 12 through the side inlet 7.

[0069] A roll 2 is performing a material changing action at a material changing position, a loading guide rail 3 is installed opposite to the material changing position, a plurality of roll ends to be loaded are stored in the loading guide rail 3, a pushing member 8 is installed on the loading guide rail 3, and the pushing member 8 pushes the roll end to separate from the loading guide rail 3, pass through the side inlet 7 and fall into the cavity 12 when the side inlet 7 is expanded.

[0070] In order to recycle the unloaded reel 2, a unloading rack 4 can be installed at a position opposite to the material changing position. The unloading rack 4 and the loading guide rail 3 are generally arranged at upper and lower positions opposite to the material changing position. A storage groove 5 is formed in the unloading rack 4, and the axial end of the unloaded reel 2 is placed in the storage groove 5. A plurality of unloaded reels 2 can be stored in the unloading rack 4.

[0071] Specifically, the unloading rack 4 can adopt the following preferred embodiment, in which the unloading rack 4 includes a horizontal frame 41 and a vertical frame 42. An arc-shaped groove is formed in the horizontal frame 41, and the vertical frame 42 is open upward. The horizontal frame 41 is installed on the frame, and the vertical frame 42 is connected to the end of the horizontal frame 41. When several prism axes 10 are arranged in sequence, the bottom prism axis 10 can be installed on the horizontal frame 41, and the top prism axis 10 can be installed in the vertical frame 42.

[0072] In the present invention, both ends of the reel 2 are mounted on the locking plate group 6, and a cavity 12 capable of assembling the end of the reel 2 is formed between the first disassembly plate 61 and the second disassembly plate 62 in the locking plate group 6. When the first disassembly plate 61 and the second disassembly plate 62 are relatively far apart, the cavity 12 is unlocked, the side inlet 7 and the side outlet 11 are expanded, the end of the reel 2 is automatically unloaded from the side outlet 11, and the end of the new reel 2 enters the cavity 12 from the side inlet, and then the end of the newly loaded reel 2 is locked, completing the automatic loading and unloading of the reel 2, thereby improving the efficiency of reel replacement.

[0073] The present invention mainly automates the loading and unloading process to form an automatic procedure. The automatic loading and unloading procedure has a fixed time. By performing this procedure, the loading of a new roll 2 can be completed before a single winding cycle is completed.

[0074] Since the end of the new roll can be directly unloaded from the side outlet 11 after being loaded into the cavity 12 from the side inlet 7, in order to prevent the roll 2 from falling directly from the side outlet 11, the side inlet 7 and the side outlet 11 are designed to be offset from each other so that the roll 2 will not fall directly from the side outlet 11 when entering the cavity 12. Specifically, the side inlet 7 is formed between the top of the first disassembly plate 61 and the top plate of the second disassembly plate 62, and the side outlet 11 is formed between the bottom end of the second disassembly plate 62 and the bottom plate of the first disassembly plate 61. The side inlet 7 is directly opposite to the loading guide rail 3, and the side outlet 11 is relatively far away from the directly opposite position of the side inlet 7.

[0075] The side inlet 7 is directly opposite to the bottom plate of the first disassembly plate 61 , and the new roll 2 will not fall from the side outlet 11 after being loaded into the cavity 12 .

[0076] Among them, the minimum width of the side inlet 7 and the side outlet 11 is smaller than the width of the prism shaft 10. In the locked state, the side inlet 7 and the side outlet 11 are both in the minimum state, which can prevent the prism shaft 10 from falling from the side outlet 11 under normal conditions.

[0077] In the present invention, Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, the first disassembly plate 61 and the second disassembly plate 62 are both right-angled plates, and are centrally symmetrical about the center position between the first disassembly plate 61 and the second disassembly plate 62 .

[0078] The right-angled plate structure and the centrally symmetrical design make it possible for the top of the second disassembly plate 62 to form a top plate, the bottom of the first disassembly plate 61 to form a bottom plate, a side inlet 7 to be formed between the top end of the first disassembly plate 61 and the top plate of the second disassembly plate 62, and a side outlet 11 to be formed between the bottom end of the second disassembly plate 62 and the bottom plate of the first disassembly plate 61.

[0079] Since the reel 2 body needs to be wound up, the locking plate group 6 cannot directly lock the reel 2. A structural setting is adopted at the axial end of the reel 2 to facilitate the locking of the reel 2. Specifically, a column shaft 9 is connected to the end of the reel 2, and a prism shaft 10 matching the cavity 12 is connected to the end of the column shaft 9. Two of the corners of the prism shaft 10 that are symmetrical about the center fit with the inner walls of the first disassembly plate 61 and the second disassembly plate 62 in the locked state. The height of the prism shaft 10 is the same as the height of the cavity 12, and the width of the prism shaft 10 is the same as the width of the cavity 12 in the locked state.

[0080] The prism shaft 10 can be locked in the cavity 12, and the column shaft 9 is used to provide a force-applying structure for the pusher 8. The pusher 8 can apply force to the column shaft 9, so that the prism shaft 10 and the column shaft 9 are forced to be loaded downward into the cavity 12 as a whole.

[0081] Since the bottom of the prism shaft 10 is supported on the bottom plate of the first disassembly plate 61 in the initial state, in order to enable the prism shaft 10 to move to the position directly opposite the side outlet 11 during the movement of the second disassembly plate 62 to complete the unloading, the present invention also makes the following design: a strong magnetic block 619 is installed on the inner wall of the second disassembly plate 62, and the strong magnetic block 619 can generate a magnetic attraction force on the prism shaft 10 in the cavity 12. The strong magnetic block 619 moves synchronously when the second disassembly plate 62 moves away from the first disassembly plate 61 and drives the prism shaft 10 to move toward the position directly opposite the side outlet 11 under the action of the magnetic attraction until the prism shaft 10 can directly pass through the side outlet 11 for unloading.

[0082] Since the prism 10 is a rectangular parallelepiped structure, the side wall of the prism 10 can completely contact the strong magnetic block 619, so that the strong magnetic block 619 applies sufficient magnetic force to the side wall of the prism 10. Under the action of the magnetic force, the prism 10 will move with the second disassembly plate 62 to the side away from the first disassembly plate 61, so that the entire prism 10 is exposed above the side outlet 11, and the prism 10 can pass through the side outlet 11 to complete the unloading.

[0083] During the unloading process, the magnetic force will generate friction between the prism 10 and the second disassembly plate 62. To achieve the above process, it is necessary to make the magnetic force generated by the second disassembly plate 62 sticking to the prism 10 in the initial state greater than the friction between the prism 10 and the first disassembly plate 61, so it is sufficient to resist the friction to achieve movement. The overall gravity of the reel 2 is greater than the friction between the prism 10 and the side wall of the second disassembly plate 62, so that the gravity exerted on the prism shaft 10 can resist the friction to achieve falling.

[0084] In addition, when the prism 10 of the loading reel 2 is loaded onto the bottom plate of the first disassembly plate 61, it will also be affected by the magnetic force of the strong magnetic block 619. However, since there is a certain distance between the second disassembly plate 62 and the prism 10 at this time, the magnetic force generated at this time is not enough to resist the friction between the prism 10 and the first disassembly plate 61 and attract the prism 10 to move toward the second disassembly plate 62. Therefore, after the prism 10 of the reel 2 is loaded, it will not move toward the side outlet 11, nor will it be unloaded from the side outlet 11.

[0085] In the present invention, the relative position between the first disassembly plate 61 and the second disassembly plate 62 is adjustable, so as to achieve the adjustment of the side inlet 7 and the side outlet 11. Specifically, the following preferred embodiment is adopted, and the second disassembly plate 62 can be adjusted along the side away from the first disassembly plate 61 to adjust the relative position between the first disassembly plate 61 and the second disassembly plate 62.

[0086] The first disassembly plate 61 is connected to a first connecting plate 63 on its side, the second disassembly plate 62 is connected to a second connecting plate 64 on its side, the first connecting plate 63 is externally connected to a first connecting column 65, the second connecting plate 64 is externally connected to a second connecting column 66, the end of the first connecting column 65 is connected to a first movable frame 67, the end of the second connecting column 66 is connected to a second movable frame 68;

[0087] The first disassembly plate 61 , the first connecting plate 63 , the first connecting column 65 and the first movable frame 67 are fixed in position, and the second disassembly plate 62 , the second connecting plate 64 , the second connecting column 66 move along the horizontal direction following the second movable frame 68 .

[0088] A first gear 69 is installed in the first movable frame 67, a second gear 610 is installed in the second movable frame 68, a driving shaft 611 is installed on the side wall of the first movable frame 67, and a mounting shaft 612 is installed on the side wall of the second movable frame 68; the first gear 69 is installed at the end of the driving shaft 611, and its center position deviates from the driving shaft 611, and the second gear 610 is installed at the end of the mounting shaft 612, and its center position deviates from the mounting shaft 612; the first gear 69 and the second gear 610 are meshed, and the distances from the meshing positions of the first gear 69 and the second gear 610 to the mounting shaft 612 and the driving shaft 611 are always consistent;

[0089] The first gear 69 acts as a driving body, driving the second gear 610 to rotate, so that the gear edges of the first gear 69 at different distances from the driving shaft 611 gradually mesh with the gear edges of the second gear 610 at different distances from the mounting shaft 612 to gradually adjust the position of the mounting shaft 612 relative to the driving shaft 611.

[0090] The first movable frame 67 is externally connected to a limiting rod 613, and the second movable frame 68 is externally connected to a mounting tube 614. The limiting rod 613 penetrates the mounting tube 614, and a spring 615 is provided between the end of the limiting rod 613 and the mounting tube 614.

[0091] The spring 615 is in a compressed state. Under the elastic force of the spring 615 , the mounting tube 614 is forced to drive the second movable frame 68 to move toward the side close to the first movable frame 67 , so that the second gear 610 is tightly against and meshes with the gear edge of the first gear 69 .

[0092] The design of the limiting rod 613 enables the second movable frame 68 to move along the direction of the limiting rod 613 , and the spring 615 always applies pressure to the installation tube 614 , that is, the second movable frame 68 is always pushed toward the first movable frame 67 side.

[0093] In the above embodiment, under the action of thrust, the second gear 610 is tightly meshed with the side of the first gear 69. In the initial state, the distance from the meshing position of the first gear 69 and the second gear 610 to the mounting shaft 612 and the driving shaft 611 is the smallest. The driving shaft 611 rotates, driving the first gear 69 to rotate, and the second gear 610 follows the rotation. During the rotation process, the distance from the meshing position of the first gear 69 and the second gear 610 to the mounting shaft 612 and the driving shaft 611 gradually increases, and the distance between the mounting shaft 612 and the driving shaft 611 increases. Since the position of the driving shaft 611 in the horizontal direction remains unchanged, the above driving process will drive the second gear 610 away from the driving shaft 611, and the second movable frame 68 will move toward the side away from the first movable frame 67. In this process, the second disassembly plate 62 will be driven horizontally away from the first disassembly plate 61 through the second connecting plate 64.

[0094] After rotating 180°, the rotation continues, and the distance from the meshing position of the first gear 69 and the second gear 610 to the mounting shaft 612 and the driving shaft 611 will gradually decrease. Through the above process, the second gear 610 is driven close to the driving shaft 611, and the second movable frame 68 moves toward the side close to the first movable frame 67. In this process, the second disassembly plate 62 will be driven by the second connecting plate 64 to approach the first disassembly plate 61 in the horizontal direction.

[0095] In order to drive the rotation of the drive shaft 611, the present invention makes the following design: Figure 7 , Figure 8 , Fig. 9 , Fig.10 As shown, the side wall of the first movable frame 67 is connected to a connecting frame 616, the end of the connecting frame 616 is connected to a mounting plate 617, a first driving motor 618 is installed inside the mounting plate 617, and the output shaft of the first driving motor 618 is connected to the driving shaft 611 to drive the driving shaft 611 to rotate.

[0096] The pusher 8 in the present invention adopts the following preferred embodiments, as Fig.11 As shown, the pusher 8 includes a mounting frame 81 mounted on the frame 14 and a first hydraulic cylinder 82 mounted on the mounting frame 81;

[0097] The output end of the first hydraulic cylinder 82 is connected to the loading guide rail 3 , and a second hydraulic cylinder 83 is installed on the top of the loading guide rail 3 . The shaft end of the second hydraulic cylinder 83 extends into the loading guide rail 3 , and faces the column shaft 9 and applies thrust to the column shaft 9 .

[0098] The first hydraulic cylinder 82 can drive the feeding guide rail 3 to move downward, and the second hydraulic cylinder 83 can push the prism shaft 10 in the feeding guide rail 3 to separate from the feeding guide rail 3.

[0099] A rubber protrusion is installed at the bottom outlet of the feeding guide rail 3, and the rubber protrusion at least partially supports the bottom of the column shaft 9 located at the bottom. The rubber protrusion prevents the prism shaft 10 from falling when the prism shaft 10 is not under force, and the prism shaft 10 can pass through the rubber protrusion and fall when the prism shaft 10 is under pressure.

[0100] like Figure 1 and Figure 2 As shown, the present invention also discloses a tape winding machine with an automatic roll changing device, comprising:

[0101] A pair of frames 14, each frame 14 is provided with a mounting seat 1, the two mounting seats 1 are arranged oppositely and parallel, and a locking plate set 6 is arranged on the mounting seats 1;

[0102] Two reels 2 are arranged at positions offset from the center between the mounting seats 1, one of the reels 2 is reeled at the reeling position, and after the reeling is completed, the mounting seat 1 rotates along the rotation direction of the reeling action to rotate the reel 2 to the material changing position, and the other reel 2 is rotated to the reeling position;

[0103] The mounting seat 1 is provided with a mounting cavity 13 for at least partially assembling the locking plate set 6. A second driving motor is installed in the mounting cavity 13. The output shaft of the second driving motor is connected to the mounting plate 617 to drive the locking plate set 6 to rotate through the mounting plate 617, so that the reel 2 follows the self-rotation to perform the winding action.

[0104] A feeding roller 15 is installed between the frames 14, and the feeding roller 15 supplies the adhesive tape 17 to the downstream end;

[0105] A plurality of conveying rollers 16 are installed between the frames 14 and at the downstream end of the feeding roller 15. The conveying rollers 16 gradually pull the adhesive tape 17 on the feeding roller 15 onto the reel 2 at the winding position.

[0106] Among them, in order to ensure the stable rotation process of the disassembly and assembly plate group 6, the installation plate 617 can also be set as a circular plate structure, and the inner wall of the installation cavity 13 fits with the outer periphery of the circular plate structure to ensure that it rotates around the inner wall of the installation cavity 13 during rotation to avoid position displacement.

[0107] In the present invention, the installation positions of the loading guide rail 3 and the unloading rack 4 must be far away from the activity area of ​​the mounting seat 1 to avoid collision.

[0108] In summary, the main implementation process of the tape winder is:

[0109] Take the case where two symmetrical reels 2 are mounted on the mounting base 1 as an example:

[0110] like Fig.12 As shown, the second drive motor drives the reel 2 and the tape reel 18 to rotate through the locking plate group 6, and drives the tape 17 to be rolled onto the tape reel 18;

[0111] After the roll is completed, Fig.13 As shown, the mounting seat 1 drives the reel 2 to change position, and the tape 17 between the reels 2 is cut. After cutting, the reel 2 located at the winding position can rotate to wind the tape, and the first drive motor 618 located at the unloading position can be driven to drive the drive shaft 611 to rotate, drive the first gear 69 to rotate, and the second gear 610 follows the rotation. During the rotation process, the distance from the meshing position of the first gear 69 and the second gear 610 to the mounting shaft 612 and the drive shaft 611 gradually increases, driving the second gear 610 away from the drive shaft 611, and the second movable frame 68 moves toward the side away from the first movable frame 67. In this process, the second disassembly plate 62 is driven to move away from the first disassembly plate 61 in the horizontal direction through the second connecting plate 64, as shown in FIG. Fig.14 and Fig.15 As shown, the side outlet 11 gradually becomes larger, the strong magnetic block 619 moves along with the second disassembly plate 62, and the prism 10 moves along with the second disassembly plate 62 to the side away from the first disassembly plate 61 under the action of the magnetic force, and the prism 10 as a whole gradually becomes exposed above the side outlet 11, and the prism 10 gradually passes through the side outlet 11 and falls onto the unloading rack 4;

[0112] The first hydraulic cylinder 82 drives the feeding guide rail 3 to move downward and close to the locking plate group 6, and the second hydraulic cylinder 83 pushes the prism shaft 10 in the feeding guide rail 3 to separate from the feeding guide rail 3. Fig.16 As shown, the prism shaft 10 is loaded onto the bottom plate of the first disassembly plate 61 through the side inlet 7;

[0113] At this time, continue to drive the first drive motor 618 to drive the drive shaft 611 to continue to rotate, and the distance from the meshing position of the first gear 69 and the second gear 610 to the installation shaft 612 and the drive shaft 611 will gradually become smaller. Through the above process, the second disassembly plate 62 is driven to approach the first disassembly plate 61 in the horizontal direction, so that the locking plate group 6 is retracted inward to lock the prism shaft 10 that has just been loaded.

[0114] In the present invention, during the disassembly and assembly of the reel 2, it is necessary to make the side inlet 7 face upward (facing the loading guide rail 3) and the side outlet 11 face downward (facing the unloading rack 4). This requires that when the locking plate group 6 has completed winding at the winding position and stopped rotating, the side inlet 7 faces downward and the side outlet 11 faces upward. After the locking plate group 6 rotates 180° following the mounting base 1, the side inlet 7 faces upward and the side outlet 11 faces downward, so as to facilitate the loading and unloading process.

[0115] In this embodiment, it is generally assumed that the sizes of the side inlet 7 and the side outlet 11 are the same. In order to further prevent the end of the roll 2 that has just been loaded into the cavity 12 from falling, the width of the side outlet 11 can also be set to be smaller than the width of the side inlet 7. Under this design, the second disassembly plate 62 needs to move a larger distance to enable the prism shaft 10 to pass through the side outlet 11 for unloading. At this time, the width of the side outlet 11 is slightly equal to the width of the prism shaft 10, and the width of the side inlet 7 must be greater than the width of the prism shaft 10. After unloading is completed, the second disassembly plate 62 can move back a distance so that the width of the side outlet 11 is less than the width of the prism shaft 10, and the width of the side inlet 7 is slightly greater than the width of the prism shaft 10. At this time, the prism shaft 10 can pass through the side inlet 7 but cannot pass through the side outlet 11, which can effectively prevent the end of the roll 2 that has just been loaded into the cavity 12 from falling from the side outlet 11.

[0116] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
