The blow-up mechanism 22 blows air between the clamping mechanism 21 and the spare material reel, so as to blow up the belt-starting end a of the spare material belt A into the clamping space. Therein, the gripping mechanism 21 is configured to controllably grip the starting end a of the material strip entering into the gripping space.

The above-mentioned starting processing device, when it is necessary to lift the starting end a of the material of the spare roll A, controls the blowing mechanism 22 to blow air between the clamping mechanism 21 and the spare roll A, thereby blowing the material of the spare roll A. The head end a of the belt is blown up into the clamping space of the clamping mechanism 21, so that the clamping mechanism 21 can clamp the head end a of the material belt that has been blown up, so as to facilitate the subsequent processing of the head end a of the material belt, for example Sticking tape, connecting with working material belt, etc.

The clamping block 212 is movably connected in the drum 211, and the above-mentioned clamping space is formed between the clamping block 212 and the material-piercing area b. The material threading area b is provided with a material threading port for the starting end a of the blown material tape to enter the clamping space. The clamping block 212 can controllably cooperate with the material threading area b of the drum 211 to clamp or loosen the starting end a of the material strip located in the clamping space.

The moving base 10 can be controllably moved along the first direction X to a first position close to the spare roll A and a second position away from the spare roll A. When the moving base 10 moves to the first position, the blowing mechanism 22 blows air toward the backup material roll A, so as to blow up the starting end a of the material tape of the backup material roll A to the clamping space. In this way, when it is necessary to lift up the head end a of the tape of the spare roll A, the blow-up mechanism 22 is controlled to blow air between the drum 211 and the spare roll A, so as to blow up the head end a of the tape of the spare roll A, and Make the starting end a of the material tape enter the clamping space through the material feeding port. Then, the control clamping block 212 cooperates with the material threading area b to clamp the head end a of the material belt. Then, the moving base 10 is controlled to move to the second position along the first direction X, so that the starting end a of the material belt follows the roller 211 to move along the first direction X, and pulls out a certain length of spare material belt.

Specifically, in the embodiment, the head processing device further includes a lift drive assembly 50 , the lift drive assembly 50 is drivingly connected with the moving base 10 to drive the moving base 10 to move along the first direction X. Optionally, the lift drive assembly 50 may be a linear drive structure such as a motor lead screw module or the like.

It should be noted that the head processing device is not limited to using the moving base 10 to move in a straight line to pull out a certain length of spare material tape. In other embodiments, the movable base 10 can also be oscillated to pull out a certain length of spare material belt. Specifically, whether to use the moving base 10 to move linearly along the first direction X or to use the swinging method can be designed according to actual needs, which is not limited here.

Further, the rotary driving member 2131 can use a motor.

Specifically, in the embodiment, the drum 211 has an identification portion (not shown). The gripping mechanism 21 also includes a detector 214 mounted on the moving base 10 . The detector 214 is used to detect the identification section passing through its identification area. When the detector 214 detects that the identification part rotates with the drum 211 to the identification area of the detector 214 , the feeding opening of the drum 211 faces the spare roll A (that is, in the embodiment shown in FIG. 1 , the feeding opening of the drum 211 downward), so that when the moving base 10 moves to the first position, the starting end a of the material of the spare material roll A that is blown up can accurately enter the clamping space in the drum 211 through the material feeding port, and then be clamped by the block. 212 clamping. Optionally, the detector 214 may be a photoelectric sensor, and the identification portion may be a notch formed on the drum 211 .

Referring to FIGS. 3 to 5 , in some embodiments, the clamping block 212 includes a connecting end 2122 and a clamping end 2123 opposite to the connecting end 2122 . The connecting end 2122 is connected in the drum 211 rotatably around a swing axis in a controlled manner, for example, the connecting end 2122 is installed in the drum 211 through a swing shaft 2124 . A clamping space is formed between the clamping end 2123 and the material threading area b of the drum 211, so that the starting end a of the material tape of the spare reel A can enter the clamping space in the drum 211 through the material threading port of the material threading area b, So that the clamped end 2123 is clamped on the inner wall of the material piercing area b of the drum 211 . That is to say, during the rotation of the connecting end 2122 around the swinging axis, the clamping end 2123 can clamp or release the starting end a of the material tape entering the clamping space through the material threading port.

In this way, in actual operation, the starting end a of the material reel A is blown up by the air flow blown by the blowing mechanism 22 , so that the starting end a of the material belt enters the clamping space in the drum 211 through the material feeding port. Then, the clamping block 212 is controlled to rotate around the swing axis, so that the clamping end 2123 is gradually approached to the inner wall of the feeding opening of the drum 211 until the head end a of the material tape is clamped on the inner wall of the feeding area b of the drum 211 .

The roller 2153 is mounted on the driving seat 215 so as to move relative to the drum 211 along with the driving seat 215 . The clamping block 212 has an inclined surface 2125 that rolls with the roller 2153 .

The two ends of the reset elastic member 216 are respectively connected with the drum 211 and the clamping block 212 to provide the elastic force for the clamping end 2123 to rotate toward the direction of releasing the starting end a of the material strip (that is, the direction away from the material-piercing area b of the drum 211 ). . During the process that the drive base 215 drives the roller 2153 to roll along the above-mentioned inclined surface 2125, the roller 2153 provides a clamp that makes the clamping end 2123 rotate toward the direction of the starting end a of the clamping tape (that is, the direction close to the threading area b of the drum 211). hold.

In this way, when it is necessary to clamp the head end a of the material tape that enters the clamping space from the feeding port, the driving seat 215 is controlled to move relative to the roller 211, thereby driving the roller 2153 to move along the inclined surface 2125 on the clamping block 212, thereby providing the The clamping block 212 has a clamping force, and driven by the clamping force, the clamping block 212 rotates around the swing axis until the clamping end 2123 of the clamping block 212 and the inner wall of the material threading area b of the drum 211 jointly clamp the starting end a of the material strip (During this process, the clamping block 212 needs to overcome the elastic force provided by the restoring elastic member 216 to rotate). When the starting end a of the material belt needs to be loosened, the driving seat 215 is controlled to move in the opposite direction relative to the roller 211, so that the clamping force exerted by the roller 2153 on the clamping block 212 disappears, so that the clamping block 212 acts on the elastic force provided by the reset elastic member 216.

Specifically, in the embodiment shown in FIG. 1 , the swing axis is parallel to the left-right direction, and the axial direction of the drum 211 is parallel to the direction perpendicular to the paper surface.

Further, the clamping driving unit also includes a clamping driving member 2181 (see FIG. 6 ) and a pushing block 2182 (see FIG. 6 ). The driving end of the component 2181 is arranged opposite to the driving seat 215 . The clamping driving member 2181 is used to drive the pushing block 2182 to move relative to the drum 211 , and to push the driving base 215 to move relative to the drum 211 . Alternatively, the clamping driver 2181 may be an air cylinder.

Of course, in another embodiment, the push block 2182 and the drive base 215 can also be directly connected, so that the push block 2182 can drive the drive base 215 to move in the axial direction of the drum 211 .

Further, a sliding rail 2151 is provided on the inner wall of the drum 211 , and a sliding block 2152 is provided on the driving seat 215 , and the sliding block 2152 is slidably matched with the sliding rail 2151 .

At this time, the backup material roll A is controlled to rotate, so as to drive the starting end a of the blown material tape to be inserted into the clamping space in the drum 211 through the material feeding port. Then, the clamping block 212 is controlled to rotate around the swing axis, so that the clamping end 2123 of the clamping block 212 cooperates with the inner wall of the threading area of the drum 211 to clamp the head end a of the material strip. Then, the moving base 10 moves from the first position to the second position, so that the starting end a of the material tape moves along the first direction X with the drum 211 . At this time, the starting end a of the material tape passes over the cutting assembly 40, so that the spare material belt that is fixed between the cutting assembly 40 and the spare material roll A can be adsorbed by the transfer device for transferring the spare material roll A, so that the spare material belt can be kept along the The state of extending in the first direction X. Then, the cutting assembly 40 cuts off the passing spare material tape, and at this time, the end of the spare material tape that is adsorbed and fixed on the transfer device becomes the starting end a of the new material tape (the part left on the clamping mechanism 21 ). It becomes the strip waste), that is, the lifting process of the starting end a of the strip of the spare coil A is completed.

The moving block 45 is connected to the driving end of the cutting driving member 44 and has a first cam groove 451 and a second cam groove 452 . The first cam 46 is mounted on the first driving portion 423 and slides with the first cam groove 451 . The second cam 47 is mounted on the second driving portion 433 and is slidingly engaged with the second cam groove 452 . During the process that the cutting drive member 44 drives the moving block 45 to move, the first cam 46 and the second cam 47 move relative to the moving block 45 along the first cam groove 451 and the second cam groove 452 respectively, thereby driving the first driving part 423 and the second cam groove 452. The two driving parts 433 are separated from or close to each other. In this way, through the cam structure, the linear motion of the moving block 45 is converted into rotational separation or close movement of the first driving part 423 and the second driving part 433, thereby driving the first blade 422 and the second blade 432 to cut the spare material tape. Alternatively, the cutting drive 44 may employ an air cylinder.

Further, the cutting assembly 40 further includes a rotating shaft 48 and an elastic member 49 . The rotating shaft 48 passes through the rotating shaft holes opened on the mounting seat 41 , the first pivoting portion 421 and the second pivoting portion 431 . Both ends of the rotating shaft 48 are provided with limit portions 481 to limit the mounting base 41 , the first pivot portion 421 and the second pivot portion 431 between the two limit portions 481 . The elastic member 49 abuts between the mounting seat 41 and a limiting portion 481 adjacent to the mounting seat 41 , thereby pressing the first shearing blade 42 and the second shearing blade 43 to ensure that the first blade 422 and the The bite degree between the second blades 432 is better, which is beneficial to improve the cutting quality of the spare material tape. Optionally, the elastic member may be a spring, and the spring is sleeved on the rotating shaft 48 .

Referring to FIG. 1 and FIG. 2 , in some embodiments, the head processing device further includes a waste collection component 60 disposed corresponding to the second position. The waste collection assembly 60 includes a fixing frame 61 , a pushing element 62 and a pushing block 63 . The pusher 62 is disposed on the fixing frame 61 and is drivingly connected with the pusher block 63 to drive the pusher block 63 to move along the axial direction of the drum 211 . When the moving base 10 moves to the second position, the pushing block 63 moves along the axial direction of the drum 211 , and pushes the scrap material on the drum 211 away from the drum 211 . Alternatively, the pusher driver 62 may be an air cylinder.

In this way, after the spare material tape is cut by the cutting assembly 40, the spare material tape wound on the drum 211 is the material tape waste. The web scrap on the drum 211 is pushed away from the drum 211 . Then, the pusher driving member 62 drives the pusher block 63 to return. Alternatively, the pusher drive 62 may employ an air cylinder. The pusher block 63 has a mating surface that matches the outer peripheral surface of the drum 211 , and the mating surface is in direct contact with the outer peripheral surface of the drum 211 . The material with waste can be. For example, if the outer peripheral surface of the drum 211 is an arc surface, the mating surface is also an arc surface.

It should be noted that, in order to enable the scrap material to be completely pushed away from the drum 211, the feed opening on the drum 211 penetrates one end of the drum 211, so that the scrap material entering the drum 211 through the feed opening can also be pushed out. The block 63 is pushed away from the drum 211 by the end which is penetrated by the feed opening.

Referring to FIG. 3 , in the embodiment, the clamping block 212 has a protruding portion 2121 , and a notch corresponding to the protruding portion 2121 is formed on the peripheral surface of the drum 211 . When the clamping end 2123 of the clamping block 212 is at the position a of the starting end a of the clamping material strip, the protrusion 2121 on the clamping block 212 penetrates the peripheral surface of the drum 211 through the corresponding notch, thereby increasing the number of windings on the drum. The perimeter of the inner ring of the spare tape on 211 (ie, the cut-off tape waste) (ie, the protrusion 2121 pierced by the notch plays the role of spreading the tape waste wound on the drum 211). When the clamping end 2123 of the clamping block 212 is at the position to release the starting end a of the material strip, the protrusion 2121 on the clamping block 212 is retracted into the drum 211 through the corresponding notch, thereby releasing the material wound on the drum 211. The strip waste is stretched so that the inner circumference of the strip waste is larger than the outer circumference of the drum 211 (that is, the strip waste will not be clamped on the drum 211 ), so that the pushing block 63 can easily remove the strip waste Push away from the drum 211 .

Optionally, the clamping block 212 has two protruding parts 2121 , and the two protruding parts 2121 are respectively located on both sides of the clamping block 212 in a direction parallel to the above-mentioned swing axis. The drum 211 has notches corresponding to the two protrusions 2121 in one-to-one correspondence. During the rotation of the clamping block 212 around the swinging axis, the two protruding parts 2121 penetrate or retract synchronously through the two notches, respectively. In this way, when the drum 211 rotates, the two protruding parts 2121 simultaneously stretch the spare material tape, and before the waste material of the material tape is pushed out, the two protruding parts 2121 are simultaneously retracted by the corresponding notch, thereby releasing the restriction on the material tape waste. Spread out, so that the perimeter of the inner ring of the waste material tape is larger than the outer circumference of the drum 211 , so as to achieve the purpose of pushing the waste material tape away from the drum 211 more easily.

Referring to FIG. 1 , in some embodiments, the blowing mechanism 22 includes a moving driving member 221 and a blowing member 223 , and the moving driving member 221 is disposed on the moving base 10 . The blowing member 223 is installed at the driving end of the moving driving member 221 , so as to be driven by the moving driving member 221 to be close to or away from the feeding opening of the drum 211 . In this way, when the head end a of the material belt needs to be lifted, firstly, the moving driving member 221 drives the blowing member 223 to move toward the feeding opening of the drum 211 until it is close to the feeding opening. Then, the blowing member 223 blows air between the drum 211 and the spare material roll A, thereby blowing up the starting end a of the material tape on the spare material roll A. At the same time, the spare material roll A is controlled to rotate at a certain angle until the starting end a of the blown material tape is driven to be inserted into the clamping space in the drum 211 through the material feeding port. Then, the head end a of the material tape in the clamping space is clamped by the clamping block 212 . The moving driving part 221 drives the air blowing part 223 to move away from the feeding opening of the drum 211 until it returns to the initial position, so as to avoid the air blowing part 223 interfering with the rotation of the drum 211 . Alternatively, the moving driving member 221 may be an air cylinder.

In some embodiments, the blowing mechanisms 22 include two, and the two blowing mechanisms 22 are respectively arranged on opposite sides of the axis of the drum 211 . In this way, according to the winding direction of the spare material tape on the spare material roll A, the blowing mechanism 22 on the right side of the drum 211 may be required to blow air to the left to blow up the head end a of the material tape, so that the spare material roll A can be blown along the Clockwise rotation can drive the starting end a of the material tape to be inserted into the feeding opening; it may also be necessary to blow air to the right by the blowing mechanism 22 on the left side of the drum 211 to blow up the starting end a of the material tape, so that the spare material roll A is counterclockwise. When rotating, it can drive the starting end a of the material belt to be inserted into the material feeding port, so the blowing mechanism 22 is provided on the opposite sides of the axis of the drum 211 (ie, the left and right sides of the drum 211), so as to ensure smooth clockwise winding. The starting end a of the spare material roll A and the counterclockwise roll A of the spare material roll A are blown up and clamped.

It should be noted that, specifically in the embodiment shown in FIG. 1 , if the starting end of the material tape of the spare material reel A is wound in the counterclockwise direction, it is necessary to use the blowing mechanism 22 on the left to blow air to the right, so as to blow air to the right. The starting end a of the material tape is blown up. At the same time, the spare material roll A is controlled to rotate counterclockwise, thereby driving the starting end a of the material belt to move to the upper left until the starting end a of the material belt is inserted into the clamping space in the drum 211 through the feeding opening.

In other embodiments, if the starting end of the material tape of the spare reel A is wound in a clockwise direction, the blowing mechanism 22 on the right side needs to be used to blow air to the left to blow up the starting end a of the material tape. At the same time, the spare material roll A is controlled to rotate clockwise, so as to drive the starting end a of the material belt to move upward to the right until the starting end a of the material belt is inserted into the clamping space in the drum 211 through the feeding opening.

The operation process of the starting processing device 30 will be described below with reference to FIG. 1 :

When it is necessary to lift up the head end a of the material tape of the spare material roll A, first, the moving base 10 is moved downward to a first position close to the spare material roll A.

Then, use the blow-up mechanism 22 to blow up the starting end a of the material tape of the spare material roll A, and control the rotation of the spare material roll A, so as to drive the starting end a of the material tape that has been blown up to gradually approach the feeding opening of the drum 211 until Enter the clamping space in the drum 211 from the material feeding port.

Then, the driving seat 215 is used to drive the clamping block 212 to rotate around the swing axis until the clamping end 2123 of the clamping block 212 clamps the head end a of the material tape on the inner wall of the material threading area b of the drum 211 .

Then, drive the drum 211 to rotate around its own axis, so that the spare material tape is wound on the drum 211 (generally, it is wound two to three times, which is not limited here).

Then, the moving base 10 moves upward to a second position away from the spare material roll A, and the transfer device absorbs and fixes the spare material tape from the position between the cutting assembly 40 and the spare material roll A. The cutting component 40 is used to cut the passing spare material tape. At this time, the starting end a of the spare material tape is adsorbed and fixed by the transfer device, and the part remaining on the drum 211 is the material tape waste.

Finally, the transfer device drives the spare roll A and the starting end a of the spare roll A to leave the starting processing device. In addition, the material pushing block 63 is used to move along the axial direction of the drum 211 to push the waste material tape away from the drum 211 .

Based on the above-mentioned starting processing device, the present invention also provides a reel changing device, which includes the starting processing device described in any of the above embodiments.

Specifically, the roll changing equipment further includes a transfer device, a tape splicing device located at the tape splicing station, and a feeding device located at the starting processing station. The head treatment device is arranged corresponding to the head treatment station.

The transfer device can be moved to the starting processing station and the splicing station. When the transfer device moves to the starting processing station, the feeding device is used to transport the spare material roll A to the transfer device, and the starting processing device is used to lift the starting end of the spare material tape, so that the starting end a of the material tape is transferred by the transfer device. fixed to keep it upright.

When the unwinding of the working material reel on the tape splicing device is completed, the tape splicing device cuts off the working material tape. The transfer device moves to the tape splicing position, and the transfer device transfers the spare material roll A to the tape splicing device, so that the starting end a of the material tape of the spare material roll A is aligned with the cut end of the working material tape. Then, the transfer device connects (eg, glues) the cut end of the working tape with the starting end a of the spare tape, so as to realize tape splicing. After the splicing is completed, the transfer device leaves the splicing station, and the splicing device continues to output the tape downstream.

It should be noted that the transfer device, the tape splicing device and the feeding device can adopt relatively mature existing technologies, as long as they can cooperate to complete the automatic roll change (that is, replace the spare roll A with the working roll), which is not limited here. .
