An embodiment of the utility model provides an automatic change of lap equipment, including unwinding device, play first processing apparatus and splicing tape device.

Referring to fig. 1 to 4, the unwinding device is used for loading a first material roll and a second material roll, which can be alternately used as a working material roll a and a standby material roll b, that is, when the first material roll is the working material roll a, the second material roll is the standby material roll b; when the first material roll is the standby material roll b, the second material roll is the working material roll a. When the unwinding device drives the work material roll a to rotate, the work material roll a unwinds and outputs the work material belt A to the downstream. It should also be noted that, in one embodiment of the present invention, the working tape a and the standby tape B may be separator, that is, the working material roll a and the standby material roll B are separator rolls. Of course, in other embodiments, the working tape a and the spare tape B may be other types of tapes, and are not limited herein.

The head start processing device includes a support mechanism 20 (see fig. 4) and a pickup mechanism 10. The support mechanism 20 is located between the work material roll a and the standby material roll b of the unwinding device. The picking mechanism 10 is used for picking up a material strip starting end B3 (see fig. 4) of the standby material strip B on the unwinding device, and drawing the material strip starting end B3 to reach between the supporting mechanism 20 and the working material strip a, so that the drawn standby material strip B is wound on the supporting mechanism 20.

The splicing device is used for pressing the first part of the adhesive tape and the spare tape B to one side of the supporting mechanism 20, so that the first part of the adhesive tape is bonded with the spare tape B. The tape splicing device is further used for pressing the working material tape A to the other opposite side of the supporting mechanism 20, cutting the working material tape A from a position between the supporting mechanism 20 and the working material roll a, and pressing the working material tape A against the second part of the adhesive tape, so that the working material tape A is bonded with the second part of the adhesive tape. At the moment, the working material belt A and the standby material belt B are bonded with the same adhesive tape, and the splicing of the working material belt A and the standby material belt B is realized.

In the automatic roll changing device, in the actual production process, initially, the working material roll a and the standby material roll b are loaded on the unwinding device, and the working material roll a is driven to rotate to convey the working material belt A to the downstream.

Referring to fig. 1 to 4, when unwinding of the work material roll a is completed, an automatic roll change is required. First, the pick-up mechanism 10 picks up the tape start end B3 of the standby material roll B on the unwinding device, and pulls the tape start end B3 to reach between the support mechanism 20 and the work material roll a, so that the pulled-out standby material tape B is wound on the support mechanism 20. At this time, the spare tape B between the supporting mechanism 20 and the spare roll B is a first spare tape section B1 (see fig. 4), and the spare tape B between the supporting mechanism 20 and the tape start end B3 is a second spare tape section B2 (see fig. 4). Then, the splicing device presses the first portion of the adhesive tape and the first spare tape segment B1 thereon against one side of the supporting mechanism 20, i.e., the first portion of the adhesive tape is stuck on the spare tape B. Then, the working material belt A and the second standby material belt section B2 are pressed against the other side of the supporting mechanism 20 by the control belt splicing device.

Then, the splicing device is controlled to cut the working material tape a from the position between the supporting mechanism 20 and the working material roll a, and the splicing device is controlled to press the working material tape a onto the second part of the adhesive tape, so that the working material tape a is bonded with the second part of the adhesive tape. At the moment, the first part of the adhesive tape is bonded with the spare material belt B, the second part of the adhesive tape is bonded with the working material belt A, namely the spare material belt B and the working material belt A are bonded together through the adhesive tape, and therefore splicing of the working material belt A and the spare material belt B is achieved.

At this time, the standby material roll b on the unwinding device is switched to the work material roll a, and is driven to rotate by the unwinding device to continuously unwind and output the work material belt A to the downstream. And, an empty material cylinder (it should be noted that the material cylinder is formed by winding a material belt on the empty material cylinder, and the material cylinder is left after the work material cylinder a is completely unreeled) on the unreeling device can be replaced by a new material cylinder, and the new material cylinder is used as a standby material cylinder b to be switched to the work material cylinder a after the next automatic roll change. The next automatic roll change process is similar to the above roll change process, and is not limited herein.

The work material roll a is a roll that is rotated by the unwinding device and conveys the work material tape a downstream. The work material tape a refers to the tape on the work material roll a. The reserve roll b refers to a roll on the unwinding device that does not transport the web downstream. The reserve tape B refers to the tape on the reserve roll B. It can be understood that after the automatic roll change, the standby roll b is switched to the working roll a to convey the working material belt A downstream; meanwhile, the unwinding of the working material roll a is completed to form an empty material roll, and the empty material roll is replaced with a new material roll, namely, the standby material roll b.

Referring to fig. 5 and 6, in an embodiment of the present invention, the picking mechanism 10 includes a mounting base 11 and a sticking component (not shown). The mounting 11 is controllably movable toward and away from the supply tape B. The gluing component comprises a tape unreeling structure 12, a tape reeling structure 13 and a gluing piece 14 which are all arranged on the mounting seat 11. The tape unwinding structure 12 is configured to output a tape carrier tape C to the sticking member 14, so that the tape carrier tape C passes through the sticking member 14, and a side of the tape carrier tape C away from the sticking member 14 is a tape carrier surface, that is, a non-tape carrier surface of the tape carrier tape C contacts the sticking member 14. The tape winding structure 13 is used for winding the tape strip C wound by the adhesive member 14. When the mounting base 11 moves close to the standby material roll B, the adhering member 14 can be driven to abut against the standby material roll B, so that the adhesive tape C on the adhering member 14 adheres to the tape starting end B3 on the standby material roll B.

Thus, when the tape start end B3 of the stock roll B needs to be picked up, (please refer to fig. 1 to 4), first, the mounting seat 11 is controlled to move close to the stock roll B until the adhering member 14 is driven to abut against the stock roll B, so that the tape C wound on the adhering member 14 adheres the tape start end B3 of the stock roll B. Then, the mounting seat 11 is controlled to move away from the standby material roll B, and the starting end B3 of the material strip on the standby material roll B is bonded and fixed on the adhesive tape strip C, so that the standby material strip B on the standby material roll B is drawn out for facilitating the subsequent splicing of the standby material strip B and the working material strip a.

The utility model discloses in utilize around gluing the sticky tape material area C on gluing 14 and glue the material area initiating terminal B3 of getting on the reserve material book B to keep away from the movement of reserve material area B and pull out the reserve material area B of reserve material book B through mount pad 11. Compare with the mode that adopts the centre gripping among the prior art, adopt sticky tape material area C to glue the mode of getting and fix material area initiating terminal B3 for it is more firm and stable to the fixed of material area initiating terminal B3, the material area initiating terminal B3 can not appear and drop and lead to can not pull out the condition in reserve material area B, and then has promoted the stability of equipment operation.

In particular, the sticking member 14 may be a sticking roller which is rotatably coupled to the mounting seat 11 about its own axis, so that the tape C can smoothly pass over the sticking roller.

Further, when the mount pad 11 drives the sticking roller to abut against the spare material roll B, the adhesive tape rolling structure 13 rolls the adhesive tape material belt C and drives the sticking roller to rotate, and the rotating direction of the sticking roller is opposite to that of the spare material roll B, so that the adhesive tape material belt C sticks one section of the spare material belt B discharged by the spare material roll B, namely, the adhesive tape material belt C sticks a longer section of the spare material belt B, so that the fixed spare material belt B is firmer, and the material belt starting end B3 is further prevented from falling off. Thus, when the tape start end B3 of the stock roll B needs to be picked up, (please refer to fig. 1 to 4), first, the mounting seat 11 is controlled to move close to the stock roll B until the sticking roller is driven to abut against the stock roll B, so that the tape C wound on the sticking roller sticks the tape start end B3 of the stock roll B. Then, sticky tape rolling structure 13 and sticky tape unwinding structure 12 drive sticky tape material area C and walk to take a section distance, meanwhile reserve material book B also rotates and unreels a section of reserve material area B, because glue the butt that the roller kept with reserve material book B, thereby make the reserve material area B who unreels out bond and fix on sticky tape material area C, except that the initiating terminal bond of reserve material area B fixes on sticky tape material area C this moment promptly, also a section of reserve material area B bond and fix on sticky tape material area C, make the adhesion to reserve material area B more firm. Then, the mounting base 11 is controlled to move away from the spare material roll B, and the material belt starting end B3 on the spare material roll B is bonded and fixed on the adhesive tape belt C, so that the spare material belt B on the spare material roll B is pulled out, and the splicing of the spare material belt B and the working material belt a is performed subsequently.

It should be noted that, in order to ensure that the standby material tape B unwound and wound off by the rotation of the standby material roll B can be adhered to the adhesive tape C, the rotation direction of the adhesion roller is driven to rotate when the adhesive tape C is unwound and is opposite to the rotation direction of the standby material roll B (i.e., as shown in fig. 2, the adhesion roller rotates clockwise, and the standby material roll B rotates counterclockwise), so that the tape direction of the adhesive tape C between the adhesion roller and the standby material roll B is the same as the unwinding direction of the standby material tape B, and the standby material tape B unwound and wound off can be adhered to the adhesive tape C.

Referring to fig. 7, in the embodiment, the tape unwinding structure 12 includes a fixed shaft 121, an unwinding roller 122 and a damper 123. The fixed shaft 121 is fixedly installed on the mount 11. The unwinding roller 122 is sleeved on the fixed shaft 121 through a bearing, so that the unwinding roller 122 can rotate around the axis of the unwinding roller relative to the fixed shaft 121. The unwinding roller 122 is used to load a roll of tape D (see fig. 1) such that the unwinding roller 122 rotates in synchronization with the roll of tape D. The damper 123 is installed between the unwinding roller 122 and the fixed shaft 121. Therefore, when the tape is unreeled, the tape roll-up structure 13 rolls up the tape strip C (see fig. 1), and under the traction action of the tape roll-up structure 13, the tape roll D on the tape roll-up structure and the unreeling roller 122 are driven to rotate relative to the fixed shaft 121, so that the tape strip C is unreeled. When the unwinding is stopped, the tape winding structure 13 stops winding the tape C, and the unwinding roller 122 stops rotating relative to the fixed shaft 121 under the damping action provided by the damper 123, i.e. stops unwinding the tape C.

Referring to fig. 8 to 10, in an embodiment, the tape winding structure 13 includes a winding roller 131 rotatably connected to the mounting seat 11 around its axis. The wind-up roller 131 has a threading slit 132 extending in its own axial direction, and the threading slit 132 is used for inserting the starting end of the tape C. The take-up roller 131 is provided inside with a pressing member 134, and the pressing member 134 is used for pressing and fixing the starting end of the adhesive tape strip C inserted into the threading slit 132. So, when installing sticky tape material book D, at first install sticky tape material book D on unreeling roller 122, then draw the initiating end of sticky tape material area C on sticky tape material book D around arrive wind-up roll 131 department after gluing the roller to insert sticky tape material area C's initiating end to wind-up roll 131 wear to take-up slit 132 in, and then utilize the piece 134 that compresses tightly in wind-up roll 131 to fix sticky tape material area C's initiating end in wearing slit 132, make wind-up roll 131 realize the rolling to sticky tape material area C when rotatory.

Further, sticky tape rolling structure 13 still includes butt seat 137 and elastic component 136, and butt seat 137 fixed mounting is in wind-up roll 131, and it installs on butt seat 137 through stop screw 135 to compress tightly piece 134 for compress tightly piece 134 can move butt seat 137 relatively. The elastic member 136 abuts between the abutting seat 137 and the pressing member 134, and the pressing member 134 is driven to move and enter the threading slit 132 under the elastic force of the elastic member 136 until the starting end of the adhesive tape strip C inserted into the threading slit 132 is pressed and fixed. Alternatively, the elastic member 136 may be a spring.

Further, the tape winding structure 13 further includes a transmission shaft 133 and a winding driving member 16 (see fig. 6), wherein the transmission shaft 133 is rotatably connected to the mounting seat 11 and coaxially connected to the winding roller 131, so that the transmission shaft 133 can drive the winding roller 131 to rotate synchronously. The winding driving member 16 is mounted on the mounting seat 11 and is in transmission connection with the transmission shaft 133 to drive the transmission shaft 133 to rotate, so that the transmission shaft 133 drives the winding roller 131 to rotate, and the winding shaft rotates to wind the adhesive tape carrier tape C.

Alternatively, the output shaft of the reel driver 16 and the transmission shaft 133 may be in transmission connection through a belt transmission structure, so that the reel driver 16 can drive the transmission shaft 133 to rotate through the belt transmission structure. Alternatively, the take-up drive 16 may employ a motor.

Referring to fig. 11 to 14, it should be noted that the tape C cannot be shaken or moved during the process of pulling out the spare tape B, which would otherwise cause the spare tape B to be pulled out or not pulled out. In order to avoid the tape C from shaking or moving during the process of drawing out the standby tape B, in one embodiment, the picking mechanism 10 further includes a first roller 181 and a pressing assembly 182. The first roller 181 is rotatably connected to the mounting base 11 around its axis and is located between the tape unwinding structure 12 and the adhering member 14. The first roller 181 is used for passing the adhesive tape strip C between the unwinding structure and the picking member 14. The pressing component 182 can controllably press the tape strip C passing through the first roller 181 onto the first roller 181, so as to prevent the tape strip C from continuously moving, and further avoid the tape strip C from shaking or moving during the process of drawing out the standby tape B. In order to prevent the first roller 181 from sticking to the tape surface of the tape C, the circumferential surface of the first roller 181 needs to be subjected to anti-sticking treatment.

Further, the compression assembly 182 includes a compression drive 1823 and a compression block 1821. The pressing driving element 1823 is installed on the mounting seat 11, and the pressing block 1821 is installed on a driving end of the pressing driving element 1823, so that the pressing driving element 1823 can drive the pressing block 1821 to get close to or get away from the first roller 181, thereby enabling the pressing block 1821 to press or loosen the tape C wound on the first roller 181.

It should be noted that at least one guiding roller 19 for the adhesive tape strip C to pass through is further disposed between the adhesive tape winding structure 13 and the adhering member 14, and the guiding roller 19 is used to guide the adhesive tape strip C, so that the adhesive tape strip C wound out by the adhesive tape unwinding structure 12 is fed onto the adhering member 14. Similarly, at least one guiding roller 19 for passing the adhesive tape strip C is also arranged between the adhering member 14 and the adhesive tape unwinding structure 12, and the adhesive tape strip C is guided by the guiding roller 19, so that the adhesive tape strip C passing through the adhering member 14 reaches the adhesive tape winding structure 13.

In the embodiment of the present invention, the picking mechanism 10 further includes a swing driving component 17, and the mounting seat 11 is installed at the driving end of the swing driving component 17, so that the swing driving component 17 can drive the mounting seat 11 to swing between the working material roll a and the standby material roll b. The mounting seat 11 can drive the sticking and picking member 14 to move close to or away from the standby material roll B in the swinging process so as to pick up the material belt starting end B3 on the standby material roll B, and further realize the drawing of the standby material belt B. Therefore, the mode of driving the mounting seat 11 to swing is adopted to drive the sticking part 14 to be close to or far away from the spare material coil b, so that the swing driving component 17 can not be arranged in the space between the working material coil a and the spare material coil b, only the part of the mounting seat 11, on which the sticking part 14 is arranged, is positioned between the working material coil a and the spare material coil b, the space between the working material coil a and the spare material coil b is greatly saved, a larger space is provided for the arrangement of other parts, and the space layout of each part is favorably optimized.

In one embodiment, the swing driving assembly 17 includes a fixed seat 171, a swing shaft (not shown), and a swing driving member 172. The mounting base 11 is rotatably connected to the fixed base 171 via a swing shaft. The swing drive 172 is drivingly connected to a swing shaft so that the swing drive 172 can swing between the roll of work material a and the roll of reserve material b by driving the mount 11 through the swing shaft. Thus, when the swing driving element 172 drives the swing shaft to rotate, the swing shaft drives the mounting seat 11 to swing, and further drives the adhering element 14 on the mounting seat 11 to approach or depart from the material roll b. Alternatively, the swing drive 172 may employ a motor.

The utility model discloses an in the embodiment, work material book a and reserve material book b are laid along first direction X interval, and mount pad 11 drives to glue and gets piece 14 and roll the swing between work material book a and reserve material book b. The head-up processing device further comprises a support mechanism 20 arranged between the work material roll a and the reserve material roll b, the support mechanism 20 being controllably movable in a second direction Y intersecting the first direction X between an avoidance position and a splicing position. Preferably, the second direction Y is perpendicular to the first direction X. Specifically, in the embodiment shown in fig. 1 to 4, the first direction X is a left-right direction, the second direction Y is an up-down direction, and the belt splicing position is located above the avoiding position.

In the process that the mounting seat 11 drives the sticking piece 14 to move away from the standby material roll B, the sticking piece 14 pulls the standby material belt B on the standby material roll B to pass through the avoidance position and the belt connecting position through the adhesive tape belt C, so that when the supporting mechanism 20 moves from the avoidance position to the belt connecting position, the standby material belt B winds around the supporting mechanism 20.

Thus, when the standby material tape B on the standby material roll B needs to be pulled out, (please refer to fig. 1 to 4), first, the mounting seat 11 is controlled to swing towards the standby material roll B until the adhering member 14 is driven to abut against the standby material roll B, so that the adhesive tape C on the adhering member 14 adheres the tape starting end B3 on the standby material roll B. The control mount 11 is then pivoted away from the reserve reel B, so that the adhesive element 14 passes through a position between the retracted position and the splicing position, so that the drawn-off reserve tape B also passes through the position between the retracted position and the splicing position. Then, the supporting mechanism 20 is controlled to move from the avoiding position to the splicing position, so that the spare tape B passing between the avoiding position and the splicing position is wound on the supporting mechanism 20. Then, the supporting mechanism 20 cooperates with the splicing device to splice the standby material tape B and the working material tape a.

In particular embodiments, the support mechanism 20 further includes an avoidance state and a splicing state. When the supporting mechanism 20 is in the avoiding state, the supporting mechanism 20 avoids the movement of the mounting seat 11 that drives the sticking element 14 away from the standby material roll B (i.e. the supporting mechanism 20 is prevented from colliding with the guiding roller 19 on the mounting seat 11), thereby ensuring that the standby material belt B on the standby material roll B can be smoothly drawn out. When the supporting mechanism 20 is in the splicing state (see fig. 16), the supporting mechanism 20 allows the spare tape B drawn out by the tape C on the adhesive member 14 to wrap around, so that the supporting mechanism 20 cooperates with the splicing device to splice the spare tape B and the working tape a on the supporting mechanism 20.

Further, the supporting mechanism 20 includes a transfer seat 22 and a supporting block 21, and the transfer seat 22 is controllably movable along the second direction Y between the retracted position and the splicing position. One end of the supporting block 21 is rotatably connected to the transfer base 22.

When the supporting mechanism 20 is in the splicing state, the length direction of the supporting block 21 (i.e., the direction perpendicular to the paper surface as shown in fig. 15) is parallel to the width direction of the spare tape B, so that the spare tape B is wound around the supporting block 21. When the supporting block 21 rotates to the avoiding position, the length direction of the supporting block 21 intersects with the width direction of the standby tape B, that is, the length direction of the supporting block 21 intersects with the axes of the guide rollers 19, so that the supporting block 21 does not collide with the guide rollers 19, and the standby tape B can be smoothly pulled out when the mounting base 11 swings. Preferably, when the supporting block 21 rotates to the avoiding position, the length direction of the supporting block 21 is perpendicular to the width direction of the spare tape B.

Optionally, the support mechanism 20 further comprises a moving drive 25, a rack 23 and a gear 24. The movable driving member 25 is mounted on the carriage 22, and the rack 23 is mounted on a driving end of the movable driving member 25. The gear 24 is mounted on the support block 21 and engaged with the rack 23. The movable driving member 25 is used for driving the rack 23 to move, so that the rack 23 drives the supporting block 21 to swing through the gear 24. Therefore, the gear 24 is engaged with the rack 23 for transmission, the linear motion output by the movable driving piece 25 is converted into the swinging motion of the supporting block 21, the structure is simple, the transmission is stable and reliable, and the occupied space is small. Alternatively, the movable drive 25 may be a pneumatic cylinder.

In an embodiment, the starting-up processing apparatus further includes a lifting driving mechanism (not shown), which is drivingly connected to the transfer base 22 to drive the transfer base 22 to move along the second direction Y between the avoiding position and the splicing position.

Optionally, the lifting driving mechanism includes a base 31 and a lifting driving member 32. The base 31 is provided with a linear rail 312 extending lengthwise in the second direction Y, and the transfer base 22 is attached to the base 31 via the linear rail 312, so that the movement of the transfer base 22 relative to the base 31 in the second direction Y is guided by the linear rail 312. The lifting drive member 32 is mounted on the base 31 and is drivingly connected to the transfer base 22 to drive the transfer base 22 to move between the retracted position and the splicing position in the second direction Y. Alternatively, the lift drive 32 may be an electric cylinder.

The movement of the transfer base 22 is not limited to the method of using the electric cylinder drive, and in other embodiments, it may be driven by a linear drive mechanism such as a screw module, for example, and is not limited thereto.

It should be further noted that, the supporting mechanism 20 cooperates with the splicing device at the splicing position to splice the working material tape a and the standby material tape B: first, the splicing device sticks a first portion of the adhesive tape to the reserve tape B on the side of the support block 21 facing the reserve roll B. Then, the tape splicing device supports the working material tape a unwound from the working material roll a to press on one side of the supporting block 21 facing the working material roll a, and cuts off the working material tape a and the spare material tape B from the position between the supporting mechanism 20 and the adhering member 14, so that the working material tape a is disconnected from the working material roll a, the spare material tape B is disconnected from the material tape start end B3 bonded on the adhesive tape material tape C, and the adhesive tape start end B3 (i.e. the cut-off end spare material tape B) bonded on the adhesive tape material tape C is also wound while the adhesive tape winding structure 13 winds the adhesive tape material tape C. Then, the splicing device presses the working material belt A against the second part of the adhesive tape. At the moment, the spare material belt B is pasted on the first part of the adhesive tape, and the working material belt A is pasted on the second part of the adhesive tape, so that the splicing of the working material belt A and the spare material belt B is realized.

It can be understood that the splicing process of the standby material belt B and the working material belt a is not limited to be implemented by adopting the above steps, as long as the splicing of the standby material belt B and the working material belt a can be implemented, and is not limited herein. The specific structure of the splicing device is not limited herein, as long as the splicing device can complete splicing of the standby tape B and the working tape a in cooperation with the supporting mechanism 20.
