Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1 and fig. 2, an embodiment of the present invention provides an automatic roll changing device, which includes a mounting frame 10, an unwinding mechanism 20, a material preparing mechanism 30, and a tape splicing mechanism 40. The unwinding mechanism 20 includes an unwinding shaft 21 rotatably connected to the mounting frame 10 about its axis. The stock preparation mechanism 30 includes a stock preparation shaft 32 and a pusher 33 (see fig. 6). The supply spool 32 has a butt end 320. The stock shaft 32 is rotatably connected to the mounting frame 10 about a rotation axis. The pusher 33 is used to provide axial pushing force to the stock roll on the stock spindle 32. The process of rotation of the supply shaft 32 about this axis of rotation includes a material pushing position. When the stock shaft 32 is in the pushing position, the butt end 320 of the stock shaft 32 is butted against the unwinding shaft 21, and the pushing member 33 is controlled to push the stock roll on the stock shaft 32 to be transferred to the unwinding shaft 21. It will be appreciated that the axis of rotation is not parallel to the axis of the stock shaft 32, as rotation of the stock shaft 32 to the stock position is to be achieved. Preferably, the axis of rotation is perpendicular to the axis of the stock preparation shaft 32.

The splicing mechanism 40 is provided in the mounting frame 10, and is configured to cut the work tape fed from the unwinding shaft 21 and connect the cut work tape to the stock roll on the unwinding shaft 21.

When the work material roll on the unwinding shaft 21 runs out and the material roll needs to be replaced, the automatic roll changer first cuts the work material tape fed from the unwinding shaft 21 by the tape splicing mechanism 40 and discharges the cartridge (the material roll includes the cartridge and the tape wound around the cartridge) on the unwinding shaft 21. The backup shaft 32 is then rotated around the rotation axis such that the butt end 320 of the backup shaft 32 is butted against the unwinding shaft 21, and then the pushing member 33 pushes the stock roll on the backup shaft 32 to be transferred onto the unwinding shaft 21. Finally, the cut working tape is connected to the stock roll on the unwinding shaft 21 by the tape splicing mechanism 40, thereby realizing automatic roll change. So, need be equipped with the automatic change of lap device of two sets of unwinding mechanism each other for spare among the prior art, the utility model discloses an automatic change of lap device utilizes reserve material axle 32 and pushes away material piece 33, realizes rolling up the propelling movement to unreeling axle 21 with the reserve material on the reserve material axle 32, need not be equipped with two sets of unwinding mechanism 20 to the structure of automatic change of lap device has been simplified greatly, is favorable to reducing occupation space.

It should be noted that the thrust member 33 provides an axial thrust for the stock roll on the stock spindle 32, which should be understood as: the pushing force provided by the pushing member 33 may be a pushing force itself parallel to the axial direction of the stock preparing shaft 32, or may have a component parallel to the axial direction of the stock preparing shaft 32, as long as the pushing of the stock roll on the stock preparing shaft 32 onto the unreeling shaft 21 can be achieved, and is not limited herein.

In the embodiment of the present invention, the unreeling shaft 21 is movable along the self-axial direction relative to the mounting frame 10. In this way, the deviation correction (i.e. the position of the tape in its width direction) can be achieved by the axial movement of the unwinding shaft 21 along itself.

Referring to fig. 3 and 4, in an embodiment of the present invention, the unwinding mechanism 20 further includes a first guide pillar 22, a rotating shaft 23, a first driving assembly 24, and a second driving assembly 25. The first guide post 22 is movably attached to the mounting bracket 10 along its axis. The rotary shaft 23 is axially fixed and is rotatably fitted into the first guide post 22 in the circumferential direction. That is, the first guide post 22 is a hollow post, the rotating shaft 23 is sleeved in the first guide post 22, and the rotating shaft 23 can rotate around its axis relative to the first guide post 22 and is fixed relative to the first guide post 22 in the axial direction of the rotating shaft 23. The unreeling shaft 21 is fixedly connected to one end of the rotating shaft 23, so that the unreeling shaft 21 synchronously rotates along with the rotating shaft 23, and unreeling is realized. The first driving assembly 24 is disposed on the mounting frame 10 and is in transmission connection with the first guide post 22, so that the first driving assembly 24 drives the first guide post 22 to move along its own axis relative to the mounting frame 10, thereby driving the unreeling shaft 21 to move along its own axis. The second driving assembly 25 is disposed on the first guide post 22 and is in transmission connection with the rotating shaft 23, so that the second driving assembly 25 drives the rotating shaft 23 to rotate around its axis, thereby driving the unreeling shaft 21 to rotate. In this way, the first driving assembly 24 and the second driving assembly 25 respectively drive the unreeling shaft 21 to move along the self axis and rotate around the self axis, so that the structure is simple and the operation is stable. Moreover, the rotating shaft 23 is sleeved in the first guide post 22, so that the structural volume is reduced, and the occupied space is reduced. Preferably, the first guide post 22, the rotating shaft 23 and the unreeling shaft 21 are coaxially disposed.

In a specific embodiment, the rotating shaft 23 can be mounted in the first guide post 22 by a bearing, so that the rotating shaft 23 can rotate relative to the first guide post 22 and can be fixed relative to the first guide post 22 in the axial direction.

In some embodiments, the unwind mechanism 20 further includes a cross-roller assembly 26. The roller passing assembly 26 includes a second guide post 261 and a roller passing 262. The second guide post 261 is movably coupled to the mounting bracket 10 in a direction parallel to the first guide post 22, and the second guide post 261 and the first guide post 22 are controllably coupled to or separated from each other. The over roller 262 is mounted on the second guide post 261 to guide the work tape fed from the pay-off reel 21. So, when needs rectify the work material area, control second guide pillar 261 is connected with first guide pillar 22, make second guide pillar 261 and first guide pillar 22 synchronous motion, thereby realize unreeling axle 21 and cross roller 262 and remove along the axis direction that is on a parallel with unreeling axle 21 in step, and then realize adjusting the position of material area width direction (rectify promptly), so avoided rectifying in-process work material area and cross roller 262 and produced the relative movement on unreeling axle 21's axial direction, thereby cause the phenomenon of wearing and tearing to the work material area, be favorable to improving product quality. When deviation correction is not needed, the second guide post 261 is controlled to be separated from the first guide post 22, so that the second guide post 261 and the roller 262 are prevented from being driven to move when the first guide post 22 moves along the axis of the first guide post 22 (for example, during roll changing and discharging).

In the embodiment, the driving portion 241 is fixedly connected to the first guide post 22. The second guide pillar 261 is fixedly connected with a mounting member 263. The cross-roller assembly 26 also includes a fixed clasp 264 and a movable clasp 265. The fixed clasping member 264 is mounted to the mounting member 263 and abuts against one side of the driving portion 241. The movable clasping member 265 is movably connected to the mounting member 263. The movable clasping member 265 can abut against the opposite side of the driving portion 241 during the moving process, so that the fixed clasping member 264 and the movable clasping member 265 clasp the driving portion 241, that is, the connection between the second guide post 261 and the first guide post 22 is realized. When it is necessary to separate the second guide post 261 from the first guide post 22, the movable clasps 265 may be moved so that the movable clasps 265 and the fixed clasps 264 are released and separated from the driving part 241. Alternatively, the second guide pillars 261 may include two or more parallel to each other, so that the movement stability of the over-roller 262 is improved and the shaking of the over-roller 262 is reduced; and on the other hand, can play a role of preventing the second guide post 261 from rotating.

Further, the roller assembly 26 further includes a roller mounting plate 266, the roller mounting plate 266 is fixedly connected to the second guide post 261, and the roller 262 is mounted on the roller mounting plate 266.

Specifically, in the embodiment, the roller assembly 26 further includes a first slide rail 2630 and a first driving member 267. The first slide rail 2630 is fixedly attached to the mounting member 263. The movable clasping member 265 is disposed on the first slide rail 2630 and is slidable along the first slide rail 2630. The first driving member 267 is fixedly connected to the mounting member 263 and is drivingly connected to the movable clasping member 265 for driving the movable clasping member 265 to move along the first slide rail 2630. In this way, the first slide rail 2630 and the first driving member 267 are used to realize the movement of the movable clasping member 265, so that the clasping and unclamping actions are stable and reliable. Alternatively, the first driver 267 may be a pneumatic cylinder. It is understood that the first driving member 267 can be other driving members capable of performing a linear reciprocating motion, and is not limited herein.

Further, the fixed clasping member 264 and the movable clasping member 265 are respectively located on both sides of the driving portion 241 in the direction perpendicular to the first guide post 22, so as to prevent interference with the movement of the first guide post 22 along its axis when the fixed clasping member 264 and the movable clasping member 265 release the driving portion 241.

Further, a side of the driving portion 241 facing the movable clasping member 265 has an engaging groove which can be engaged with the movable clasping member 265. In this way, the stability when the movable clasping member 265 and the fixed clasping member 264 clasp the driving portion 241 is further improved. Alternatively, both the fixed clasps 264 and the movable clasps 265 may be rollers. When the fixed clasp 264 and the movable clasp 265 are loosened, the fixed clasp 264 may roll on the surface of the driving portion 241, reducing friction.

In some embodiments, the over-roller assembly 26 further includes a lock 268 and a lock lever 269. The locking member 268 is fixedly attached to the mounting member 263 and the locking lever 269 is fixedly attached to the mounting bracket 10. The locking rod 269 is parallel to the second guide post 261 and the locking member 268 is controllably connected to or disconnected from the locking rod 269. In this way, when no correction is required, the second guide post 261 is separated from the first guide post 22, and at this time, the lock 268 is connected to the lock lever 269 in order to prevent the roller 262 from moving. When deviation correction is needed, the locking piece 268 is separated from the locking rod 269, and the second guide post 261 is connected to the first guide post 22, so that the second guide post 261 and the first guide post 22 can synchronously move along the axial direction of the first guide post 22, that is, the roller 262 and the unreeling shaft 21 synchronously move along the axial direction of the unreeling shaft 21, and deviation correction is further achieved. Alternatively, lock 268 may be a jaw cylinder.

In some embodiments, the first driving assembly 24 includes a first lead screw 242, a first lead screw nut 243, and a slider 244. One end of the first lead screw 242 is rotatably connected to the mounting frame 10 around its axis and is parallel to the first guide post 22. The first lead screw nut 243 is threadedly coupled to the first lead screw 242. The slider 244 is fixedly attached to the first guide post 22 and the first lead screw nut 243. In this way, the first lead screw nut 243 is driven to move along the first lead screw 242 by the rotation of the first lead screw 242, so as to drive the sliding member 244 and the first guide post 22 to move along the axial direction of the first guide post 22, and further drive the unreeling shaft 21 to move along the axis thereof. Further, the driving portion 241 is fixedly connected to the slider 244.

In one embodiment, the first driving assembly 24 further includes a third guide post 245, a first mounting seat 246, and a screw driving member 247. One end of the third guide post 245 is fixedly connected to the mounting frame 10 and parallel to the first guide post 22. The first mounting seat 246 is fixedly coupled to the other end of the third guide post 245. The screw rod driving member 247 is mounted on the first mounting seat 246 and is in transmission connection with an end of the first screw rod 242 away from the mounting frame 10, so that the screw rod driving member 247 drives the first screw rod 242 to rotate around its axis. Further, the sliding member 244 is disposed on the third guide post 245 and is slidable along the third guide post 245, so as to guide the sliding member 244, and the movement of the sliding member 244 is more stable. Specifically, the lead screw drive 247 may be a motor.

Alternatively, the output shaft of the lead screw driving member 247 may be connected to the first lead screw 242 by a coupling transmission.

In order to make the movement of each sliding part more stable, the slider 244 may be slidably mounted to the third guide post 245 through a guide sleeve. The first guide post 22 may also be slidably mounted to the mounting bracket 10 via a guide sleeve. The second guide post 261 can also be slidably mounted to the mounting bracket 10 through a guide sleeve.

In some embodiments, the second driving assembly 25 includes a second mounting seat 251, a rotary driving member 252 and a transmission structure. The second mount 251 is fixedly connected to the first guide post 22. The rotary driver 252 is mounted to the second mount 251. The transmission structure is connected between the rotary driving member 252 and the rotary shaft 23 in a transmission manner, so that the rotary driving member 252 drives the rotary shaft 23 to rotate around the axis thereof, thereby driving the unreeling shaft 21 to rotate around the axis thereof. In one embodiment, the second mount 251 is fixedly connected to the sliding member 244.

In particular, in one embodiment, the transmission structure includes a drive gear 253 and a driven gear 254 that intermesh. The driving gear 253 is mounted to an output shaft of the rotary driving member 252 such that the driving gear 253 and the output shaft of the rotary driving member 252 rotate synchronously. The driven gear 254 is mounted to the rotary shaft 23 such that the driven gear 254 rotates in synchronization with the rotary shaft 23. In this way, the rotation motion output from the rotary drive 252 is transmitted to the rotary shaft 23 via the driving gear 253 and the driven gear 254 that mesh with each other, and the rotary shaft 23 is driven to rotate. The transmission structure is not limited to the gear transmission structure, and may be a belt transmission structure, for example, and is not limited herein. Alternatively, the rotary drive may be an electric motor.

It should be noted that the unwinding shaft 21 and the roller 262 are located on the same side of the mounting frame 10, so that the tape paid out by the unwinding shaft 21 is guided by the roller 262. The first guide post 22 and the second guide post 261 penetrate through two opposite sides of the mounting frame 10, and the third guide post 245 is located on a side of the mounting frame 10 facing away from the unreeling shaft 21.

In the embodiment of the present invention, the material preparing mechanism 30 further includes a pushing member 34 (see fig. 1). The stub shaft 32 also has a push end 322 opposite the butt end 320. The pushing member 34 is fixedly connected to the pushing end 322. The stock shaft 32 also includes a stock position during rotation about the axis of rotation. When the preparation shaft 32 is in the preparation position, the pushing member 34 faces the unwinding shaft 21 for pushing the preparation roll on the unwinding shaft 21. After the pushing member 33 pushes the stock roll on the stock shaft 32 to the unwinding shaft 21, the unwinding shaft 21 moves along the axis thereof in a direction away from the stock shaft 32, and the stock shaft 32 rotates around the axis to the stock preparing position, so that the pushing member 34 faces the unwinding shaft 21. The unwinding shaft 21 is then moved along its axis in a direction approaching the standby shaft 32, and the pushing member 34 is pressed against the standby material roll on the unwinding shaft 21, so that the standby material roll and the unwinding shaft 21 are moved along the axis of the unwinding shaft 21, so as to adjust (i.e. position) the position of the standby material roll on the unwinding shaft 21. Optionally, the pushing member 34 includes a body fixedly connected to the pushing end 322 and a plurality of pushing claws arranged around the body. Each pushing claw extends towards one side of the body departing from the pushing end 322 and is used for contacting with the stock roll on the unreeling shaft 21 so as to push the stock roll. Thus, the unwinding shaft 21 is prevented from contacting the abutting member 34.

It should be noted that, in order to prevent the stock roll 21 and the stock roll on the stock roll 21 from interfering with the movement of the abutting piece 34 in the process of rotating the stock shaft 32 to the stock preparing position around the rotation axis, before rotating the stock shaft 32 to the stock preparing position, the stock roll 21 needs to move along the axis thereof in the direction away from the stock shaft 32, thereby avoiding the position effectively. After the material preparing shaft 32 rotates to the material preparing position, the unwinding shaft 21 moves along the axis thereof to the direction close to the material preparing shaft 32, and meanwhile, the material preparing roll on the unwinding shaft 21 is pushed by the pushing member, so that the material preparing roll is positioned on the unwinding shaft 21.

In the embodiment, the positioning block 27 is disposed on the unreeling shaft 21. In this way, the stock roll on the unwinding reel 21 is pushed by the pushing member 34 until the stock roll is positioned by the positioning block 27, i.e. the stock roll is pushed in place.

It should be noted that the positioning of the stock roll on the unwinding shaft 21 is not limited to the installation of the pushing member on the stock shaft 32, and in other embodiments, a separate pushing mechanism may be designed. Referring to fig. 8, the pushing mechanism includes a pushing shaft 52 and a pushing member 53, and the pushing shaft 52 is rotatably connected to the mounting frame 10 around its axis. The urging member 53 is mounted on the urging shaft 52. The urging piece 53 includes an urging position during the rotation of the urging shaft 52 about its axis. When the pushing member 53 is located at the pushing position, the pushing member 53 is located between the unwinding shaft 21 and the stock shaft 32 for pushing the stock roll on the unwinding shaft 21.

Thus, after the material pushing member 33 pushes the material roll on the material preparing shaft 32 to the material releasing shaft 21, the material releasing shaft 21 moves along its own axis in a direction away from the material preparing shaft 32, the pushing shaft 52 of the pushing mechanism rotates to drive the pushing member 53 to be located at the pushing position, and at this time, the pushing member 53 is located between the material releasing shaft 21 and the material preparing shaft 32. Then, the unwinding shaft 21 moves along its axis toward the end close to the stock shaft 32, so that the pushing member 53 tightly pushes the stock roll on the unwinding shaft 21, and pushes the stock roll in place. Finally, the pushing shaft 52 rotates to drive the pushing member 53 to rotate to the initial position, and the unreeling shaft 21 moves to the working position along its own axis.

In one embodiment, the pushing mechanism includes a third mounting seat 54 and a pushing driving member 55. The third mounting seat 54 is fixedly mounted to the mounting bracket 10. The pushing shaft 52 is rotatably connected to the third mount 54 about its axis. The pushing driving member 55 is disposed on the third mounting seat 54 and is connected to the pushing shaft 52 in a driving manner to drive the pushing shaft 52 to rotate around its axis.

Further, the push driving member 55 may be a cylinder. The pushing mechanism further includes a driving block 57 and a hinge base 56. The driving block 57 is fixedly connected to the pushing shaft 52, and the hinge base 56 is fixedly connected to the third mounting base 54. The fixed end of the pushing drive member 55 is hinged to the hinge seat 56, and the hinge axis is parallel to the axis of the pushing shaft 52. The driving end of the pushing drive member 55 is hinged to the driving block 57, and the hinge axis is parallel to and non-collinear with the axis of the pushing shaft 52. In this way, the driving end of the pushing driving member 55 extends and contracts, so that the pushing shaft 52 is driven to rotate around the axis thereof, and the pushing member 53 is driven to swing.

Further, the pushing mechanism further includes a rotary supporting seat 57, and the rotary supporting seat 57 is fixedly connected to the third mounting seat 54. The pushing shaft 52 is disposed through the rotating support 57 and can rotate relative to the rotating support 57. Specifically, the pushing shaft 52 is mounted to the rotation support base 57 through a bearing.

In the embodiment, the pushing mechanism further includes an adjusting block 58, an adjusting rod 59, and a first elastic member 591. The adjusting block 58 is fixedly connected to the pushing shaft 52, and the pushing member 53 is movably mounted on one end of the pushing shaft 52 along the axis of the pushing shaft 52. One end of the adjusting rod 59 penetrates through the adjusting block 58 and is connected to the pushing member 53. The first elastic member 591 is disposed on a side of the adjusting block 58 away from the abutting member 53, one end of the first elastic member 591 abuts against the adjusting rod 59, and the opposite end abuts against the adjusting block 58, so as to provide a pre-tightening force that the abutting member 53 tends to move toward the adjusting block 58 along the axis of the abutting shaft 52. Alternatively, the first elastic member 591 may be a compression spring. The compression spring is sleeved on the adjusting rod 59 and located on one side of the adjusting block 58 away from the pushing element 53. Optionally, the adjusting rod 59 is a screw rod, and the screw rod is connected to the pushing member 53 in a threaded manner.

In this way, when the pushing element 53 is in the pushing position (i.e. between the unwinding shaft 21 and the stock preparation shaft 32), the unwinding shaft 21 moves along its axis toward the stock preparation shaft 32, and the stock preparation roll on the unwinding shaft 21 contacts the pushing element 53, so as to compress the first elastic element 591 for buffering, and the pushing element 53 is supported by abutting against the stock preparation shaft 32. When the unwinding shaft 21 continues to move along its axis towards the stock shaft 32, the resisting piece 53 pushes the stock roll on the unwinding shaft 21 to move relative to the unwinding shaft 21, so that the stock roll reaches the working position.

Further, the pushing mechanism further includes a guide rod 592. The guide rod 592 penetrates the adjusting block 58 and is slidable relative to the adjusting block 58, and one end of the guide rod 592 is fixedly connected to the abutting member 53. In this manner, the guide rod 592 can guide the abutting member 53 to slide along the axis of the abutting shaft 52. It will be appreciated that the guide rods 592 are parallel to the push shaft 52.

Referring to fig. 5, 6 and 7, in an embodiment of the present invention, the material preparing shaft 32 is a hollow shaft. At least one sliding groove 321 is formed on the circumferential side wall of the material preparing shaft 32. The slide groove 321 extends lengthwise in the axial direction of the stock shaft 32. The pushing member 33 is slidably disposed in the material preparing shaft 32 along the axial direction of the material preparing shaft 32, and extends out of the material preparing shaft 32 from the corresponding sliding groove 321. Thus, the stock roll is sleeved on the stock shaft 32, and when the pushing member 33 slides along the sliding groove 321, the part of the pushing member 33 extending out of the sliding groove 321 pushes the stock roll to move along the stock shaft 32 until the stock shaft 32 is pushed onto the unreeling shaft 21.

In some embodiments, the material preparation mechanism 30 further includes a material pushing driving assembly, which includes a material pushing screw 361, a material pushing screw nut 35, and a material pushing driving member 36. The pushing screw 361 is disposed in the material preparing shaft 32 and is rotatable with respect to the material preparing shaft 32. The pushing screw nut 35 is screwed to the pushing screw 361. The pushing piece 33 and the pushing screw nut 35 are relatively fixed. The pushing driving member 36 is mounted at one end of the standby shaft 32 and is in transmission connection with the pushing screw 361 to drive the pushing screw 361 to rotate. Thus, when the stock roll on the stock shaft 32 needs to be pushed to the unwinding shaft 21, the pushing driving member 36 drives the pushing screw 361 to rotate, so as to drive the pushing screw nut 35 to move along the pushing screw 361, and further drive the pushing member 33 to move along the pushing screw 361 (i.e. move along the axial direction of the stock shaft 32). It will be appreciated that the pusher screw 361 is axially parallel to the stock shaft 32. Preferably, the pushing screw 361 is coaxially disposed within the preparation shaft 32.

In particular embodiments, the pusher drive assembly further includes a drive bevel gear 362 and a driven bevel gear 364 that intermesh. A drive bevel gear 362 is mounted to the output shaft of the pusher driver 36, and a driven bevel gear 364 is mounted to one end of a pusher screw 361. In this way, the transmission between the material pushing driving piece 36 and the material pushing screw 361 is realized by the driving bevel gear 362 and the driven bevel gear 364 which are engaged with each other. Alternatively, the pusher actuator 36 may be a motor.

Specifically, in the embodiment, the pushing driving assembly further includes a driving wheel 37 fixedly sleeved outside the pushing screw nut 35. The pusher 33 is fixedly connected to a drive wheel 37.

In order to guide the driving wheel 37, in one embodiment, the pushing drive assembly further includes a pushing guide bar fixedly mounted in the material preparing shaft 32, the pushing guide bar being parallel to the axis of the material preparing shaft 32 and extending through the driving wheel 37, and the driving wheel 37 being slidable along the pushing guide bar. Thus, the pushing guide rod is used for guiding the movement of the driving wheel 37, so that the movement of the pushing piece 33 is more stable, and the pushing action is stable and reliable. It should be noted that, in another embodiment, the pushing guide bar may not be provided, and the movement of the driving wheel 37 may be guided by the inner wall of the standby shaft 32. That is, the driving wheel 37 is slidably engaged with the circumferential inner wall of the material preparation shaft 32 so that the driving wheel 37 can slide along the circumferential inner wall of the material preparation shaft 32, thereby guiding the movement of the driving member 37.

In a specific embodiment, the pushing driving assembly further includes a guiding roller mounted on the driving wheel 37, and the guiding roller is in rolling fit with the sliding groove 321 to roll along the sliding groove 321, so as to guide the driving wheel 37 and the pushing element 33 to move along the axial direction of the material preparing shaft 32, so that the pushing of the pushing element 33 is more stable. Because the guide rollers are arranged for guiding, the pushing member 33 can only penetrate out of the standby shaft 32 through the sliding groove 321, and is not in contact with the inner wall of the sliding groove 321 for guiding, so that abrasion caused by contact between the pushing member 33 and the inner wall of the sliding groove 321 is avoided.

More specifically, two sliding grooves 321 are formed in the material preparing shaft 32, and each sliding groove 321 is correspondingly provided with one material pushing member 33. So, set up two and push away material piece 33 and move along two spout 321 respectively for it is more stable to push away material of material piece 33. Two runners 321 are located at the bottom of the supply shaft 32.

In particular embodiments, preparation mechanism 30 further includes a first sensor 391. The detection port is formed on the circumferential side of the stock shaft 32. The first sensor 391 is attached to the detection port for detecting the position of the drive wheel 37. In this way, the detection of the position of the driving wheel 37 by the first sensor 391 can limit the range of motion of the driving wheel 37, preventing the driving wheel 37 from colliding with the components at both ends of the standby shaft 32. It is understood that the driving wheel 37 is provided with a sensing block corresponding to the first sensor 391.

In particular, in the embodiment, the preparation shaft 32 has at least one preparation position for the material supply roll. Each material preparation position is provided with a second sensor. The second sensor is used for detecting whether the corresponding stock preparation position is sleeved with a stock roll. In this way, the second sensor 392 can detect whether each stock location on the stock spindle 32 has a stock roll.

Preferably, the number of the first sensors 391 is two, the number of the detection ports is also two, the two detection ports are arranged at intervals along the axial direction of the material preparation shaft 32, and the two first sensors 391 are respectively installed in the two detection ports. In order to avoid the second sensor 392 from affecting the material preparing shaft 32 to load the material preparing roll, a detecting groove can be arranged on the periphery of the material preparing shaft 32, and the detecting groove is communicated with the two detecting ports. A plurality of second sensors 392 are disposed in the detection groove. Further, the material preparation mechanism 30 further includes a cover plate 393, and the cover plate 393 covers the detection groove for preventing the second sensor 392 from falling off. The cover 393 has a detection notch corresponding to the second sensor 392. The second sensor 392 detects the stock roll through the corresponding detection notch.

In particular embodiments, stock preparation mechanism 30 further includes a plurality of guide wheels 323. The circumferential side surface of the material preparation shaft 32 is provided with a guide groove longitudinally extending along the axial direction of the material preparation shaft 32, and the plurality of guide wheels 323 are arranged in the guide groove and arranged along the longitudinal extending direction of the guide groove. Each guide wheel 323 partially protrudes from the peripheral side surface of the supply shaft 32. In this way, the guide wheel 323 guides the movement of the stock roll along the axial direction of the stock shaft 32, so that the movement of the stock roll is more stable. Optionally, the guide slot opens at the top of the preparation shaft 32.

In a particular embodiment, wear strips 326 are provided on the circumferential side wall of the stock preparation shaft 32. The wear strips 326 extend lengthwise along the axial direction of the stock preparation shaft 32. The wear strips 326 are used to prevent wear of the stock spindle 32 when the stock roll is moved frequently on the stock spindle 32. Further, a circumferential side wall of the stock preparation shaft 32 is provided with a mounting groove for mounting the wear-resistant strip 326. The wear strip 326 partially protrudes from the peripheral side surface of the stub shaft 32.

In an embodiment, the material preparing shaft 32 has a tightening groove formed on the circumferential outer surface of the butt end 320, and the material preparing mechanism further includes a tightening assembly 327 disposed in the tightening groove. The tensioning assembly 327 is controllably movable radially along the stock preparation axis 32 to extend or retract the tensioning slot. When the tensioning assembly 327 moves along the radial direction of the material preparing shaft 32 to extend out of the tensioning slot, the tensioning assembly 327 tensioning the material preparing roll sleeved on the butt end 320, and at this time, the material preparing roll is fixed relative to the material preparing shaft 32, i.e., the material preparing roll cannot move along the axial direction of the material preparing shaft 32, so as to prevent the material preparing roll from being thrown out under the action of centrifugal force during the rotation process of the material preparing shaft 32. When the tensioning member 327 moves along the radial direction of the material preparing shaft 32 to retract into the tensioning slot, the tensioning member 327 releases the tensioning of the roll of material sleeved on the butt end 320, and the roll of material can move along the axial direction of the material preparing shaft 32 to facilitate roll change.

Further, the tensioning assembly 327 includes a tensioning block and an expansion member. The tensioning block is arranged in the tensioning groove of the material preparing shaft 32, and the tensioning block can move along the radial direction of the material preparing shaft 32 to extend out of or retract into the tensioning groove. The expansion piece is arranged between the bottom wall of the tensioning groove and the tensioning block. The expansion member is controllably expandable or contractible to drive the tensioning block in radial movement along the stock preparation axis 32. Alternatively, the inflation member may be a balloon. When the stock roll needs to be fixed, the airbag is inflated, so that the tensioning block can move outwards along the radial direction of the stock shaft 32, and the tensioning block extends out of the tensioning groove, so that the stock roll is fixed relative to the stock shaft 32. When the stock roll does not need to be fixed, the air bag is deflated, so that the tensioning block can move inwards along the radial direction of the stock shaft 32, and the tensioning block retracts into the tensioning groove, thereby loosening the stock roll.

In one embodiment, the stock preparation mechanism 30 further includes a first end cap 324 and a second end cap 325 fixedly mounted to the butt end 320 and the pushing end 322 of the stock preparation shaft 32, respectively. Opposite ends of the pusher screw 361 are rotatably coupled to the first and second end caps 324 and 325, respectively, by bearings.

In one embodiment, material preparation mechanism 30 further includes a mounting bracket 311, a rotating bracket 312, a material preparation driving member 313, and a material preparation transmission assembly. The mounting bracket 311 is fixedly mounted to the mounting bracket 10, and the rotating bracket 312 is rotatably coupled to the mounting bracket 311 about a rotating axis. The pushing end 322 of the material preparing shaft 32 is fixedly connected to the rotating bracket 312. The material preparation driving member 313 is disposed on the mounting frame 10, and the material preparation transmission assembly is connected between the material preparation driving member 313 and the rotating bracket 312 in a transmission manner, so that the material preparation driving member 313 drives the rotating bracket 312 to rotate around the rotating axis through the material preparation transmission assembly, thereby realizing that the material preparation shaft 32 can rotate around the rotating axis. Alternatively, the mounting bracket 311 and the stock drive 313 are located on opposite sides of the mounting bracket 10.

Further, the stock driving assembly includes a stock driving wheel 314, a stock driven wheel 315, a stock driving belt 316, and a stock rotating shaft 317. The rotating bracket 312 is rotatably coupled to the mounting bracket 311 about a rotation axis by a stock rotation shaft 317. The stock capstan 314 is mounted to the output shaft of the stock drive member 313 for synchronous rotation with the output shaft of the stock drive member 313. The stock follower 315 is mounted to the stock rotation shaft 317 to rotate in synchronization with the stock rotation shaft 317. The material preparing belt 316 is sleeved between the material preparing driving wheel 314 and the material preparing driven wheel 315, so that the material preparing driving wheel 314 and the material preparing driven wheel 315 rotate synchronously. It should be noted that the stock material transmission assembly is not limited to the belt transmission, and in other embodiments, a gear transmission may be used, for example, and is not limited herein. Alternatively, the stock drive 313 may be an electric motor.

Referring to fig. 1 and 9, in an embodiment of the present invention, the automatic reel changer further includes a waste collecting mechanism 60 for discharging the cartridge on the unwinding shaft 21. The waste collection mechanism 60 is used to discharge the cartridges on the payout shaft 21 before the stock roll on the stock shaft 32 is pushed onto the payout shaft 21, requiring the cartridges on the payout shaft 21 to be discharged.

The waste collection mechanism 60 includes a gripper assembly 62 rotatably connected to the mounting frame 10 about a first axis. The gripper assembly 62 includes a gripping position and a dispensing position during rotation about the first axis. When the grabbing assembly 62 is in the grabbing position, the grabbing assembly 62 is used for grabbing the material barrel on the unreeling shaft 21; when the gripper assembly 62 is in the emptying position, the gripper assembly 62 releases the cartridge. When the roll of work material on the unwinding shaft 21 is running low, the work material tape fed from the unwinding shaft 21 is cut by the tape splicing mechanism 40. The gripper assembly 62 is then rotated about the first axis to a gripping position and grips the cartridge on the payout shaft 21. Then, the payout shaft 21 is moved along the axis, thereby separating the cartridge from the payout shaft 21. Subsequently, the gripper assembly 62 is rotated about the first axis to the emptying position, i.e. the cartridge separated from the emptying shaft 21 is transferred to the emptying position and released. That is to say, realized unloading the waste material voluntarily, avoided adopting the manual work to unload, reduced the cost of labor, improved production efficiency.

In some embodiments, the grasping assembly 62 includes a rotating shaft 621, a second drive 622, a first swing arm 623, and a grasping hand 624. The rotating shaft 621 is rotatably connected to the mounting frame 10 about its axis. It is understood that the axis of the rotating shaft 621 is the first axis. The second driving member 622 is disposed on the mounting frame 10 and is connected to the rotating shaft 621 in a transmission manner so as to drive the rotating shaft 621 to rotate around its axis. One end of the first swing arm 623 is fixedly connected to the rotating shaft 621, and the hand grip 624 is disposed at the other end of the first swing arm 623. Thus, when the second driving member 622 drives the rotating shaft 621 to rotate and drive the hand 624 to the grasping position, the hand 624 grasps the cartridge on the unwinding shaft 21, i.e. the cartridge is fixed relative to the hand 624. The payout shaft 21 is then moved along its axis so that the cartridge is separated from the payout shaft 21. Then the second driving member 622 drives the rotating shaft 621 to rotate, so as to drive the hand grip 624 to the discharging position, and at this time, the hand grip 624 releases the material cylinder, thereby discharging the material cylinder on the discharging shaft 21. Alternatively, the grippers 624 may be gripper cylinders.

In one embodiment, the grabbing assembly 62 further comprises a first sliding block 625 and a third driving member 626. The first slider 625 is slidably coupled to the first swing arm 623 in a lengthwise direction of the first swing arm 623. The hand grip 624 is disposed on the first slider 625. The third driving member 626 is disposed on the first swing arm 623 and is drivingly connected to the handle 624 for driving the handle 624 to move along the longitudinal direction of the first swing arm 623. When the first swing arm 623 rotates to the discharging position around the first axis, the third driving element 626 drives the hand grip 624 gripping the material cylinder to move along the longitudinal direction of the first swing arm 623, so that the hand grip 624 is close to the material storage area, the material cylinder is easily discharged, and the impact is avoided. Alternatively, the third driver 626 may be a cylinder.

Further, one side of the first swing arm 623 has a guide rail 6232, and the first slider 625 is disposed on the guide rail 6232 and can slide along the guide rail 6232. The opposite side of the first swing arm 623 is provided with a third driver 626. That is, the first slider 625 and the third driver 626 are respectively located at opposite sides of the first swing arm 623. In this manner, movement of the finger grip 624 is more smooth and reliable.

In an embodiment, the output shaft of the second driving member 622 can be connected to the rotating shaft 621 through a coupling transmission. Alternatively, the second driver 622 may be a motor. More specifically, the second driving member 622 may be fixedly mounted on the mounting frame 10 through a fixing seat, so as to ensure the connection stability of the second driving member 622 and reduce the vibration of the second driving member 622.

In some embodiments, the waste collection mechanism 60 further includes a storage assembly 64. The storage assembly 64 is located below the grasping assembly 62. The storage assembly 64 includes a slide 641. The carriage 641 has a plurality of storing areas for storing the cartridges arranged at intervals in the first direction (the "plurality" of the plurality of storing areas should be understood as two or more). The slide 642 is slidably connected to the mounting frame 10 in a first direction to sequentially move the plurality of magazine areas to below the discharge position for receiving the cartridges released by the gripper 624. In this manner, the gripper assembly 62 releases the cartridge in the emptying position so that the cartridge falls into the storage area. And when one storage area is full of cartridges, the slide 641 moves in the first direction to move the other storage area to below the discharge position.

Preferably, the first direction is parallel to the first axis. In this manner, the volume occupied by the garbage collection mechanism 60 in the direction perpendicular to the first axis is advantageously reduced.

In one embodiment, the storage assembly 64 further includes a second lead screw and a fourth driver 643. The second screw is rotatably connected to the mounting frame 10 about its own axis. The sliding base 641 is screwed to the second lead screw. The fourth driving element 643 is disposed on the mounting frame 10 and is connected to the second lead screw in a transmission manner to drive the second lead screw to rotate around its own axis. In this way, the fourth driving part 643 drives the second screw rod to rotate, so that the sliding seat 641 moves along the axis direction of the second screw rod, and the multiple material storage areas are sequentially moved to the lower side of the material discharging position. It will be appreciated that the axis of the second lead screw is parallel to the first direction. More specifically, the storage assembly 64 also includes a second lead screw nut. The second screw rod nut is in threaded connection with the second screw rod. The sliding base 641 is fixedly connected to the second lead screw nut. That is, the slide 641 is indirectly screwed to the second lead screw through the second lead screw nut.

Further, the storage assembly 64 also includes a guide rod 644. One end of the guide rod 644 is fixedly connected to the mounting bracket 10. And is parallel to the second screw rod. The slider 641 is slidably connected to the guide rod 644. In this way, the guide rod 644 guides the sliding of the sliding seat 641, so that the sliding seat 641 moves more stably and reliably.

Alternatively, the fourth driver 643 may be an electric motor. The output shaft of the fourth driving element 643 may be connected to the second lead screw through a coupling.

In particular embodiments, the storage assembly 64 also includes two support rods 645. The two support rods 645 are fixedly connected to the sliding base 641. The two support bars 645 are spaced apart and parallel to the first direction. A storage space for carrying the cartridge is formed between the two support bars 645. The magazine space includes a plurality of magazine areas arranged in a first direction. So, can place the feed cylinder in the storage area in storage space from two bracing pieces 645 tops for two bracing pieces 645 bear the weight of the feed cylinder and realize the storage. When the cartridge is to be removed, it is separated from the support bar 645 by lifting the cartridge upward. It should be noted that the distance between the two support bars 645 is smaller than the diameter of the cartridge in order to carry the cartridge.

Further, storage assembly 64 also includes a plurality of dividers 646. A plurality of partitioning members 646 are fixedly attached to the two support bars 645 and are arranged at intervals in the longitudinal direction of the support bars 645 to partition the plurality of magazines (i.e., a partitioning member 646 is provided between every adjacent two magazines). That is, the plurality of partitions 646 divide the magazine space into a plurality of magazine areas each for storing one cartridge in the longitudinal direction of the support rod 645. In this manner, the provision of partition 646 effectively avoids interference between two cartridges located in adjacent two magazine areas.

Referring to fig. 10, 11 and 12, in an embodiment of the present invention, the tape splicing mechanism 40 includes a second swing arm 41, a clamping assembly 42 and a cutter 43. One end of the second swing arm 41 is rotatably connected to the mounting frame 10 around the second axis, the clamping assembly 42 is rotatably connected to the other end of the second swing arm 41 around the third axis, the clamping assembly 42 is used for clamping the work material belt, the cutter 43 is disposed on the second swing arm 41 and can be close to or far away from the clamping assembly 42, and the cutter 43 is used for cutting off the material belt. In this way, when a reel change is required, the clamping assembly 42 of the splicing mechanism 40 clamps the working material tape paid out from the pay-off reel 21. The knife then approaches the gripper assembly 42 to sever the gripped work material strip. The scrap collecting mechanism 60 then discharges the cartridge from the unwind shaft 21, and the pusher 33 pushes the stock roll on the stock shaft 32 onto the unwind shaft 21 and positions the stock roll on the unwind shaft 21. The clamping assembly 42 is rotated about the third axis such that the severed work material strip portion wraps outside of the clamping assembly 42. Finally, the second swing arm 41 rotates to make the work material tape clamped by the clamping assembly 42 approach the stock roll on the unwinding shaft 21 to paste the work material tape on the stock roll on the unwinding shaft 21.

Preferably, the second axis is parallel to the axis of the payout shaft 21. The third axis is parallel to the second axis.

In some embodiments, the clamping assembly 42 includes a turntable 421, a fixed nip roller 422, and a movable nip roller 423. The turntable 421 is rotatably connected to one end of the second swing arm 41 about a third axis. The fixed nip roller 422 is installed to the rotating plate 421, and the movable nip roller 423 may be connected to the rotating plate 421 toward or away from the fixed nip roller 422. In this manner, the work material strip is gripped or released by the movable nip roller 423 approaching or moving away toward the fixed nip roller 422. That is, when the work material tape needs to be nipped, the movable nip roller 423 is moved toward a direction close to the fixed nip roller 422, thereby nipping the work material tape between the movable nip roller 423 and the fixed nip roller 422. When it is necessary to release the work material tape after the work material tape is attached to the stock roll, the movable nip roller 423 is moved away from the fixed nip roller 422, thereby releasing the work material tape. Also, when the work material tape is attached to the stock roll, the turntable 421 rotates so that the cut work material tape portion wraps around the fixed nip roller 422 or the movable nip roller 423 and faces the stock roll for attachment. It should be noted that, in order to better grip the working tape paid out from the pay-off shaft 21, both the movable nip roller 423 and the fixed nip roller 422 are parallel to the second axis, i.e., parallel to the pay-off shaft 21.

In particular embodiments, one of the fixed nip roller 422 and the movable nip roller 423 may be rotatable about its axis. That is, when the fixed nip roller 422 and the movable nip roller 423 clamp the work tape, the fixed nip roller 422 or the movable nip roller 423 may be driven to rotate around its axis when the work tape is pulled by a certain external force. Thus, the second swing arm 41 rotates to make the work material tape clamped by the movable nip roller 423 and the fixed nip roller 422 approach the stock roll on the unwinding shaft 21 until the fixed nip roller 422 or the movable roller 423 wrapped with the work material tape abuts against the stock roll, so that the work material tape is adhered to the stock roll. The spare material roll rotates along with the unreeling shaft 21, so that the fixed clamping roller 422 or the movable roller 423 is driven to rotate around the axis of the spare material roll through the working material belt, the tail end of the working material belt is completely pasted on the spare material roll, and the phenomenon that powder falls off due to the fact that the tail part of the working material belt is not pasted on the spare material roll and powder easily shakes in the tape moving process is avoided, and the product quality is affected is avoided. Preferably, the fixed nip roller 422 is rotatable about its axis. In this manner, before the strip of work material is applied to the stock roll, the turntable 421 is rotated so that the cut strip of work material partially wraps around the stationary nip roller 422 and faces the stock roll.

In one embodiment, the clamping assembly 42 further comprises a fifth driving member 424 disposed on the rotating plate 421. The fifth driving member 424 is drivingly connected to the movable nip roller 423 to drive the movable nip roller 423 toward or away from the fixed nip roller 422. More specifically, the movable nip roller 423 is mounted to the driving end of the fifth driving member 424 through a movable nip roller holder. Optionally, the fifth driver 424 may be a jaw cylinder.

In an embodiment, the fixed nip roller 422 may also be fixedly connected to the rotating disc 421 through the fixed nip roller seat, so that the connection of the fixed nip roller 422 is more stable.

Further, the clamping assembly 42 further includes a second elastic member disposed between the movable clamping roller seat and the fixed clamping roller seat, and the second elastic member is used for providing a pre-tightening force that enables the movable clamping roller seat to have a moving trend of moving away from the fixed clamping roller seat. So, the setting of second elastic component plays the cushioning effect on the one hand, causes the rigidity to strike and damages the work material area to the work material area when avoiding activity clamp roll 423 and fixed clamp roll 422 centre gripping work material area. On the other hand, the fifth driving member 424 drives the movable nip roller 423 and cooperates with the fixed nip roller 422 to nip the work material tape while compressing the second elastic member. When the work tape needs to be loosened, the fifth driving member 424 releases the force, and the movable nip roller 423 moves away toward the fixed nip roller 422 by the second elastic member, thereby loosening the work tape. Therefore, the fifth driving part 424 can adopt a single-air-path clamping jaw air cylinder, so that the air path is reduced, and the risk of air path winding is reduced.

In one embodiment, the tape splicing mechanism 40 further includes a fixing frame 44, a second slider 45 and a sixth driving member 46. The mount 44 is fixedly attached to the mount 10. The second slider 45 is movably connected to the fixed frame 44 in a direction parallel to the second axis. The end of the second swing arm 41 remote from the clamping assembly 42 is rotatably connected to the second slider 45 about the second axis. The sixth driving member 46 is mounted on the fixed frame 44 and is connected to the second sliding block 45 in a driving manner, so as to drive the second sliding block 45 to move along a direction parallel to the second axis. In this way, when it is necessary to clamp the strip of work material paid out from the pay-off reel 21, the sixth driving member 46 drives the second slider 45 to move in a direction parallel to the second axis (i.e., in a direction parallel to the pay-off reel 21), so as to drive the fixed nip roller 422 and the movable nip roller 423 of the nip assembly 42 to move in a direction parallel to the second axis, so that the strip of work material is inserted between the fixed nip roller 422 and the movable nip roller 423. The movable nip roller 423 is then moved toward the fixed nip roller 422 to effect a nip of the strip of work material between the movable nip roller 423 and the fixed nip roller 422. Alternatively, the sixth drive 46 may be a translation cylinder.

Furthermore, the fixed frame 44 has a second slide rail 441 thereon, and the second slider 45 is slidably disposed on the second slide rail 441. That is, the second slider 45 can slide along the second slide rail 441.

In one embodiment, the belt connecting mechanism 40 further includes a swing shaft 47 and a seventh driving member 48. The pendulum shaft 47 is rotatably connected to the second slider 45 about its own axis. One end of the second swing arm 41, which is far away from the clamping assembly 42, is fixedly mounted on the swing shaft 47, so that the second swing arm 41 and the swing shaft 47 can synchronously rotate. The seventh driving member 48 is disposed on the second slider 45 and is connected to the swing shaft 47 in a transmission manner to drive the swing shaft 47 to rotate around its axis. It will be appreciated that the axis of the pendulum shaft 47 is the second axis described above. In this way, the seventh driving element 48 drives the swing shaft 47 to rotate, so that the end of the second swing arm 41 away from the clamping assembly 42 rotates around the second axis. When the cut working tape needs to be adhered to the stock roll, the seventh driving element 48 drives the swing shaft 47 to rotate, so that the second swing arm 41 drives the clamping assembly 42 to rotate to the stock roll on the unwinding shaft 21, and simultaneously the rotating disc 421 rotates, so that the cut working tape partially wraps the fixed clamping roller 422 or the movable clamping roller 423 and faces the stock roll. Further, the output shaft of the seventh driving member 48 is connected to the swing shaft 47 through a coupling transmission. Alternatively, the seventh driver 48 may be an electric motor.

Further, the clamping assembly 42 further includes an eighth driving member 49 and a transmission assembly, wherein the eighth driving member 49 is fixedly installed relative to the second sliding block 45. The transmission assembly is in transmission connection between the eighth driving member 49 and the rotating disc 421, so that the eighth driving member 49 drives the rotating disc 421 to rotate through the transmission assembly.

Further, the drive assembly includes a drive shaft 491. The transmission shaft 491 is respectively connected with the eighth driving member 49 and the rotary disc 421 in a transmission manner so as to transmit the rotary motion output by the eighth driving member 49 to the rotary disc 421. Further, the transmission assembly further includes a driving pulley 492, a main transmission pulley 493, a first transmission belt 494, a secondary transmission pulley 495, a driven pulley 496, and a second transmission belt 497. The driver 492 is mounted to the output shaft of the eighth driver 49 to rotate in synchronism with the output shaft of the eighth driver 49. A main drive wheel 493 is mounted on one end of the drive shaft 491 for synchronous rotation with the drive shaft 491. The first belt 494 is disposed between the driving wheel 492 and the main driving wheel 493 for synchronously rotating the driving wheel 492 and the main driving wheel 493. A secondary drive wheel 495 is mounted on the other end of drive shaft 491 for synchronous rotation with drive shaft 491. Driven wheel 496 is mounted to turntable 421 for synchronous rotation with turntable 421. The second belt 497 is disposed between the secondary driving wheel 495 and the driven wheel 496 for allowing the secondary driving wheel 495 and the driven wheel 496 to rotate synchronously. Thus, the output shaft of the eighth driving member 49 rotates to drive the driving wheel 492, the main driving wheel 493, the transmission shaft 491, the auxiliary driving wheel 495, the driven wheel 496 and the turntable 421 to rotate in sequence. It should be noted that the transmission connection between the transmission shaft 491 and the eighth driving member 49 and the rotating disc 421 is not limited to a belt transmission, and in other embodiments, the transmission connection may be realized by a gear transmission, a chain transmission, etc., and is not limited herein.

Further, the transmission shaft 491 may be a hollow shaft. The transmission shaft 491 is coaxially sleeved outside the swing shaft 47 and is rotatable relative to the swing shaft 47. Thus, the transmission shaft 491 and the swing shaft 47 are sleeved, so that the structure is more compact, the structure is simplified, and the occupied space is reduced. Alternatively, drive shaft 491 may be coaxially mounted outside of pendulum shaft 47 by a bearing.

In one embodiment, the belt splicing mechanism 40 further comprises a sliding plate 451 and a swing shaft mounting block 452. The sliding plate 451 is fixedly connected to the second slider 45. The seventh driving member 48 is fixedly mounted on the sliding plate 451. The swing axle mount 452 is fixedly attached to the sliding plate 451. The pendulum shaft 47 is rotatably connected to the pendulum shaft mount 452 about its axis. The transmission shaft 491 is sleeved outside the swing shaft 47. The eighth driving member 49 is fixedly mounted on the swing shaft mounting seat 452. Alternatively, the second slider 45 may include two or more than two, so as to further improve the stability of the action of the splicing mechanism 40.

In one embodiment, the clamping assembly 42 further comprises a rotating shaft 425, and the rotating shaft 425 is rotatably connected to the second swing arm 41 around the axis of the rotating shaft 425. The rotation plate 421 is fixedly connected to the rotation shaft 425 to rotate synchronously with the rotation shaft 425. Driven pulley 496 is fixedly mounted to shaft 425 for synchronous rotation with shaft 425. Further, the rotating shaft 425 is provided with a central hole along the axis thereof, and the air passage of the fifth driving member 424 is arranged to penetrate through the central hole of the rotating shaft 425 and is connected with the air connector. Thus, the air passage winding caused by the rotation of the rotating shaft 425 can be avoided.

In some embodiments, the splicing mechanism 40 further includes a cutting drive 431 and a cutter seat 432. A cutting driving member 431 is fixedly installed at the second swing arm 41, a cutter seat 432 is fixedly installed at a driving end of the cutting driving member 431 and faces the clamping member 42, and a cutter 43 is installed at one end of the cutter seat 432 facing the clamping member 42. The cutting driving member 431 drives the cutter holder 432 toward and away from the clamp assembly 42 so that the cutter 43 cuts the work material tape clamped by the movable nip roller 423 and the fixed nip roller 422 and then returns to the original position. Alternatively, the cutting drive 431 may be a pneumatic cylinder.

Referring to fig. 3, 13 and 14, in an embodiment of the present invention, the unwinding mechanism further includes a guiding assembly for guiding the work tape paid out by the unwinding shaft 21. The guiding assembly comprises a supporting base 71, a rotating wheel 72, a guiding driving member 73, a rotating arm 76 and a guiding roller 77.

The supporting base 71 is fixedly connected to the mounting frame 10 and has a shaft hole for the first guide post 22 to pass through. Since the support base 71 is fixed with respect to the mounting frame 10, the first guide post 22 is movable with respect to the mounting frame 10 along its own axis, and therefore the first guide post 22 is movable with respect to the support base 71 along its own axis. The rotary wheel 72 is rotatably connected to the support 71 about the axis of the shaft hole. The guiding driving member 73 is disposed on the mounting frame 10 and is drivingly connected to the rotating wheel 72 to drive the rotating wheel 72 to rotate around the axis of the shaft hole. One end of the rotating arm 76 is fixedly connected to the rotating wheel 72, and a guide roller 77 is provided at the other end of the rotating arm 76. In this way, the guiding driving member 73 can drive the rotating wheel 72 to rotate, so as to drive the rotating arm 76 and the guiding roller 77 to rotate with the rotating wheel 72, and the position of the guiding roller 77 can be adjusted to guide the work material tape. Compare along linear motion with guide roll 77 among the prior art, because install guide roll 77 through revolution mechanic in this embodiment, and first guide pillar 22 is located to supporting seat 71 accessible shaft hole cover for compact structure reduces occupation space, uses more in a flexible way.

In the embodiment, the axis of the shaft hole is collinear with the axis of the unreeling shaft 21, so that the position adjustment of the guide roller 77 is more flexible, and the occupied space is further reduced. Further, the axis of the guide roller 77 is parallel to the axis of the shaft hole, that is, the guide roller 77 is parallel to the unwinding shaft 21, so that the tape fed from the unwinding shaft 21 can be guided more favorably.

In particular embodiments, the pivot arm 76 extends lengthwise in a direction perpendicular to the axis of the shaft hole.

In some embodiments, the guide assembly further includes a guide drive wheel 74 and a guide drive belt 75. The guide driving pulley 74 is mounted to an output shaft of the guide driving member 73 to rotate in synchronization with the output shaft of the guide driving member 73. The guide belt 75 is disposed between the guide driver 74 and the rotation wheel 72, so that the guide driver 74 and the rotation wheel 72 rotate synchronously. That is, the guide driver 73 drives the rotation wheel 72 to rotate by means of a belt transmission. Alternatively, the guide drive 73 may be a motor.

In some embodiments, the supporting base 71 includes a mounting portion and a shaft portion fixedly connected to one side of the mounting portion. The shaft hole penetrates the mounting part and the shaft part in sequence. The mounting portion is for fixed mounting to the mounting bracket 10. The rotating wheel 72 is rotatably sleeved outside the shaft portion. In one embodiment, the rotating wheel 72 may be mounted to the shaft portion via a bearing. The mounting portion may be mounted to the mounting bracket 10 by, for example, welding, threaded fastener fastening, or the like.

Referring to fig. 15, based on the automatic roll changing device, the present invention further provides a roll changing method, including the steps of:

s100: the work tape fed from the unwinding shaft 21 is cut by the tape splicing mechanism 40, and the cartridge on the unwinding shaft 21 is discharged.

Specifically, the sixth driving member 46 drives the second slider 45 to move in a direction parallel to the second axis (i.e., in a direction parallel to the axis of the pay-off spool 21) so that the work tape is inserted between the fixed nip roller and the movable nip roller. Then the fifth driving piece drives the movable clamping roller to move towards the fixed clamping roller, so that the working material belt is clamped. Then, the cutting driving member 431 drives the cutter to cut the work tape.

The second driving member 622 drives the rotating shaft 621 to rotate, so as to drive the gripping handle 624 to the gripping position, and the gripping handle 624 grips the material cylinder on the unwinding shaft 21, i.e. the material cylinder is fixed relative to the gripping handle 624. The payout shaft 21 is then moved along its axis so that the cartridge is separated from the payout shaft 21. Then the second driving member 622 drives the rotating shaft 621 to rotate, so as to drive the hand grip 624 to the discharging position, at this time, the hand grip 624 releases the material cylinder, and the material cylinder falls into the material storage area to be collected.

Further, in order to facilitate the insertion of the work material strip between the fixed nip roller and the movable nip roller, the work material strip may be rotated by the rotation wheel 72 of the guide assembly, thereby adjusting the position of the work material strip using the guide roller 77 such that the work material strip is aligned with the gap between the fixed nip roller and the movable nip roller.

S200: the standby shaft 32 is rotated such that the butt end 320 of the standby shaft 32 is butted against the payout shaft 21. The pusher 33 then pushes the stock roll on the stock spool 32 to the payout spool 21.

Specifically, the standby shaft 32 is rotated such that the butt end 320 of the standby shaft 32 faces the payout shaft 21. The unreeling shaft 21 is then driven to move along its axis toward the docking end 320 so that the unreeling shaft 21 is docked in contact with the docking end 320. The pusher 33 on the supply spool 32 moves along the supply spool 32 to push the supply roll on the supply spool 32 onto the payout shaft 21.

S300: the cut work tape is connected to the stock roll on the unwinding shaft 21 by the tape splicing mechanism 40.

Specifically, the eighth driving member 49 drives the rotary table 421 to rotate, so that the portion of the work material tape is wrapped on the fixed nip roller 422 or the movable nip roller 423.

The seventh driving element 48 drives the second swing arm 41 to rotate around the swing shaft 47, so that the fixed nip roller 422 or the movable nip roller 423 wrapped with a part of the work material tape contacts with the stock roll on the unwinding shaft 21, thereby bonding the work material tape to the stock roll (for the convenience of the connection of the material tape, the starting end of the stock material tape of the stock roll has a double-sided adhesive, and the double-sided adhesive is bonded with the work material tape). Unreel the axle 21 and rotate to the stock roll that drives on unreeling the axle 21 rotates, and then drives fixed nip roller 422 or activity nip roller 423 through the work material area and rotate around self axis, makes the whole afterbody in work material area all paste on stock roll. Then, the fifth driving piece drives the movable clamping roller to move away from the fixed clamping roller, so that the working material belt is loosened.

The sixth driving member 46 drives the second slider 45 to move along a direction parallel to the second axis, and the seventh driving member 48 drives the second swing arm 41 to rotate around the swing shaft 47, so that the tape splicing mechanism 40 returns to the original position.

Further, in order to avoid the working material belt being driven by the belt splicing mechanism 40 in the process of returning to the original position, the working material belt can be picked up by the guide roller 77 of the guide assembly, so that the working material belt is separated from the belt splicing mechanism 40. When the splicing mechanism 40 returns to the original position, the guide roller 77 of the guide assembly drives the work material tape to a proper position for unwinding.

In some embodiments, step S201 is further included after step S200: the stock roll on the payout shaft 21 is urged into position along the axis of the payout shaft 21.

Specifically, in one embodiment, step S201 specifically includes: the unreeling shaft 21 moves along its own axis in a direction away from the stock shaft 32, and the stock shaft 32 rotates so that the urging piece 53 on the stock shaft 32 faces the unreeling shaft 21. The unwinding shaft 21 moves along its axis in a direction approaching the stock roll 32, so that the pushing member 53 pushes the stock roll on the unwinding shaft 21 into position (i.e. the stock roll contacts the positioning block 27). It can be understood that the movement of the unreeling shaft 21 along its own axis in a direction away from the standby shaft 32 is for avoiding a position, and the standby shaft 32 is prevented from rotating so that the pushing piece 53 on the standby shaft 32 interferes with the pushing piece 53 when facing the unreeling shaft 21.

In another embodiment, step S201 specifically includes: the unreeling shaft 21 moves in a direction away from the standby shaft 32 along its own axis. The pushing shaft 52 of the pushing mechanism rotates around its own axis to drive the pushing member 53 to rotate to the pushing position, i.e. the pushing member 53 is located between the material preparing shaft 32 and the unreeling shaft 21. The unwinding shaft 21 moves along its axis in a direction approaching the stock roll 32, so that the pushing member 53 pushes the stock roll on the unwinding shaft 21 into position (i.e. the stock roll contacts the positioning block 27).

It should be noted that when the abutting end 320 of the preparation shaft 32 is away from the unreeling shaft 21, the abutting end 320 of the preparation shaft 32 may abut with a loading device such as an AGV to load one or more rolls of preparation on the preparation shaft 32.
