In this embodiment, the cutting knife 3 is disposed between the first conveying unit 1 and the second conveying unit 2 (the cutting knife 3 of this embodiment is disposed near the end of the first conveying unit 1) and is used for sequentially cutting the leading end portion a1 and the trailing end portion a2 of the source reel a conveyed by the first conveying unit 1, that is, the source reel a is sequentially cut by the cutting knife 3 in the direction perpendicular to the reel conveying direction, wherein the source reel a is gradually conveyed forward by the first conveying unit 1 toward the cutting knife 3, the cutting knife 3 is operated to cut the leading end portion a1 of the source reel a when the leading end portion of the source reel a is moved to the cutting point position preset by the cutting knife 3, then the source reel a is driven forward by the first conveying unit 1 toward the second conveying unit 2, at this time, the source reel a is gradually transferred onto the second conveying unit 2 (the source reel a is gradually conveyed forward by the first conveying unit 1 and the trailing end portion B toward the second conveying unit 2) and gradually conveyed forward by the source reel a is continuously moved forward by the first conveying unit 2 and the cutting knife 2 a is continuously moved forward by the first conveying unit 2 toward the leading end portion B when the leading end portion of the source reel a is continuously moved forward by the cutting knife 3 to the leading end portion 2 and the leading end portion of the source reel a is continuously moved from the leading end portion 2 a is continuously moved toward the leading end portion 2B of the second conveying unit 2.
Referring to fig. 1 and 2, in order to further ensure the cutting effect and the cutting stability of the cutting knife 3, a front holding member 51 and a rear holding member 52 are respectively arranged at the front and rear of the cutting point of the cutting knife 3, wherein the front holding member 51 and the rear holding member 52 of the present embodiment are axially arranged in the front and rear, and the front holding member 51 and the rear holding member 52 serve to assist in stabilizing the roll transportation, that is, the front holding member 51 and the rear holding member 52 of the present embodiment are composed of a fixed clamping die 511 and a movable clamping die 512 which can be opened and closed in opposite directions, so that the roll is clamped or retracted by the opening and closing actions of the fixed clamping die 511 and the movable clamping die 512, and when the roll moves to the set position, the fixed clamping die 511 and the movable clamping die 512 are closed to clamp the roll, so that the roll is temporarily stopped at the set position; when the fixed clamping die 511 and the movable clamping die 512 are loosened to avoid the winding drum, the winding drum is not blocked from moving forward.
In addition, the movable clamping die 512 of the present embodiment may be configured with a telescopic cylinder driving the movable clamping die 511 to reciprocate transversely, and the telescopic end of the telescopic cylinder is connected with the movable clamping die 512, so that the movable clamping die 512 is driven to reciprocate transversely by the telescopic action of the telescopic cylinder, and further the folding and releasing actions of the fixed clamping die 511 and the movable clamping die 512 are realized. Thus, at the time of the cutting action of the cutting blade 3, with the front holding member 51 or the tail holding member 52 for temporarily holding the front end portion or the tail end portion, respectively, of the source roll A, the auxiliary support of the front holding member 51 or the tail holding member 52 for the source roll A is achieved so that the cutting blade 3 action cuts off the head end portion a1 and the tail end portion a2, respectively, of the source roll A, that is, first, the source roll A is conveyed forward by the first conveying unit 1 in the axial direction of the source roll A to the front holding member 51, and then, the front holding member 51 is operated to hold the front end portion of the source roll A (the front end portion of the source roll A, which at this time, jumps the cutting point of the cutting blade 3, serves as the head end portion a 1), so that the head end portion a1 of the source roll A is temporarily stopped at the cutting point of the cutting blade 3, the cutting blade 3 at this time is correspondingly operated to cut the leading end portion a1 of the source roll a (predetermined by adjusting the running speed and time of the first conveying unit 1 with respect to the length of the leading end portion a1 to be removed by the cutting source roll a), after the leading end portion a1 is completely cut off, the front holding member 51 is operated to unwind the source roll a and the source roll a continues to advance under the urging of the first conveying unit 1, and then gradually transferred to the second conveying unit 2 through the tail holding member 52 (during the gradual transfer, the tail end portion of the source roll a gradually comes off the first conveying unit 1 and the front end portion gradually transfers to the second conveying unit 2), until the tail end portion of the source roll a advances to the tail holding member 52, the tail holding member 52 is operated to hold the tail end portion of the source roll a (at this time, the tail end portion of the source roll a that has not jumped over the cutting point of the cutting blade 3 serves as the tail end portion a 2), so that the tail end a2 of the source roll a is briefly stopped at the cutting point of the cutting blade 3, the cutting blade 3 at this time is correspondingly operated to cut the tail end a2 of the source roll a (predetermined by adjusting the running speed and time of the second conveying unit 2 with respect to the length of the tail end a2 to be removed by the cutting source roll a), after the tail end a2 is completely cut to form the long roll B, the tail holding member 52 is operated to release the long roll B and the long roll B is continuously advanced away from the tail holding member 52 by the driving of the second conveying unit 2 until the long roll B is completely conveyed onto the second conveying unit 2; the above-described process is repeated cyclically, and the first conveying unit 1 and the second conveying unit 2 continue conveying to achieve continuous production processing.
Further, the fixed clamping die 511 and the movable clamping die 512 of this embodiment may adopt a ring structure arranged transversely as shown in fig. 2, and may also adopt a plate-like structure or a ring structure arranged vertically, as long as the clamping of the winding drum can be realized according to the circumferential shape of the winding drum, so that the present application is not limited to the specific structures of the movable clamping die 511 and the movable clamping die 512, and other derivative schemes may also be adopted.
Further, since the front holding member 51 and the rear holding member 52 are disposed adjacently with a gap therebetween through which the cutting edge of the cutting blade passes, the head end portion a1 and the tail end portion a2 cut by the cutting blade 3 are cut in the rear holding member 52 and the front holding member 51, respectively. That is, when the cutting blade 3 cuts the head end portion a1, the head end portion a1 is cut in the tail holding member 52, then the head end portion a1 is pushed away from the tail holding member 52 by the front end of the source roll a, and finally the blanking gap 100 between the tail holding member 52 and the second conveying unit 2 falls; when the cutting blade 3 cuts the tail end portion a2, the tail end portion a2 is cut in the front holding member 51, then the tail end portion a2 is pushed away from the front holding member 51 and the tail holding member 52 in order by the front end of the next source roll a, and finally the blanking gap 100 between the tail holding member 52 and the second conveying unit 2 falls. Since the head end portion a1 or the tail end portion a2 is dropped from the blanking gap 100, the cut head end portion a1 or the cut tail end portion a2 is prevented from obstructing the conveyance of the roll, and the occurrence of the accumulation of the head end portion a1 or the tail end portion a2 at the front holding member 51 and the tail holding member 52 to affect the operation of the front holding member 51 and the tail holding member 52 can be effectively prevented.
In the present embodiment, the front end portion and the rear end portion of the source roll a are held by the front holding member 51 and the rear holding member 52, respectively, so that the source roll a is prevented from being deformed by the cutting force of the cutting blade 3, and the quality of cutting is prevented from being affected.
As shown in fig. 7, the slitting knife 4 of the present embodiment is located at the end of the second conveying unit 2, so that the rolls (the rolls here include the active roll a or the long roll B) cut by the slitting knife 3 are gradually conveyed to the slitting knife 4 for segmented cutting under the driving of the second conveying unit 2, so that the source roll a or the long roll B is segmented to obtain the desired finished rolls a3 (the lengths of the finished rolls a3 at the cut positions are equal in length, and the length of the finished rolls a3 to be obtained by the cutting of the long roll B is predetermined by adjusting the operation speed and time of the second conveying unit 2), that is, the movement of the second conveying unit 2 is intermittent and synchronous with the slitting knife 4: upon stopping the response of the second conveying unit 2, the slitting knife 4 is operated so that the roll at the slitting knife 4 is slit, and during the movement of the second conveying unit 2, the slitting knife 4 is not operated and does not block the roll from passing through the slitting knife 4, wherein when the front end portion of the source roll a from which the leading end portion a1 is slit off by the slitting knife 3 is gradually jumped over the slitting knife 4 by a predetermined length (when the trailing end portion a2 of the source roll a is not slit off) under the common drive of the first conveying unit 1 and the second conveying unit 2, or when the front end portion of the long roll B from which the trailing end portion a2 is slit off by the slitting knife 3 is gradually jumped over the slitting knife 4 by a predetermined length under the drive of the second conveying unit 2, the second conveying unit 2 is stopped to operate and the slitting knife 4 is operated so as to slit the roll (including the source roll a or the long roll B) in the vertical roll axial direction to obtain a length of the finished roll a3, in actual production, in order to realize efficient production and save the occupied space of a cutting and slitting system, the actual length of the winding drum is far greater than the gap length between the cutting cutters 3 and 4, so that when the source winding drum A is conveyed on the second conveying unit 2 to move forward to the cutting point of the cutting cutter 4 for slitting, the tail end part of the source winding drum A is not moved to the cutting point position of the cutting cutter 4 (the tail end part a2 of the source winding drum A is not cut), the front end part of the source winding drum A is continuously cut into a finished winding drum a3 by the cutting cutter 4 until the tail end part a2 of the source winding drum A is cut by the cutting cutter 3, the long winding drum B is conveyed to move forward for segmented cutting only under the action of the second conveying unit 2, to achieve continuous segmented cutting of the reels. In addition, a receiving conveyor belt 6 is arranged downstream of the slitting knife 4 to receive and convey the finished product roll a3 obtained by slitting to a predetermined downstream station.
As shown in fig. 8 and fig. 9, in this embodiment, the slitting knife 4 continuously segments the source reel a or the long reel B to slit and form a plurality of finished reels a3, in order to further realize continuous slitting of the reels, the distance between the slitting knife 3 and the slitting knife 4 in this embodiment is an integer multiple of the length value of the finished reel a3 formed by cutting by the slitting knife 4, and for convenience of understanding, the explanation will be specifically made in combination with practical situations: let the length of the finished roll a3 cut be X, and the distance between the cutting knife 3 and the slitting knife 4 be Y, then y=n×x (n=1, 2,3,4 …). Meanwhile, in the process of transferring the source reel A of the end part a1 of the cut head from the first conveying unit 1 to the second conveying unit 2, the conveying speed of the first conveying unit 1 is faster than that of the second conveying unit 2 by accelerating the conveying speed of the first conveying unit 1 (the conveying speed of the first conveying unit 1 is changed by changing the rotating speed of the servo motor), the front end part of the source reel A at the moment accelerates and advances in the second conveying unit 2 (the first conveying unit 1 at the moment acts on the tail end part of the source reel A correspondingly to accelerate and advances on the second conveying unit 2, so that the source reel is accelerated and advanced on the second conveying unit 2), until the front end of the source reel which is accelerated and conveyed contacts with the tail end of the reel which is previously transferred to the second conveying unit 2, and then the conveying speed of the first conveying unit 1 is slowed down, the first conveying unit 1 is made to have a conveying speed equal to or slightly slower than that of the second conveying unit 2 (the first conveying unit 1 of the present embodiment should be approximately synchronized with the conveying speed of the second conveying unit 2, avoiding the situation that the drum is decelerated due to the difference in speed therebetween and the front end thereof comes into contact with the rear end of the preceding drum, and then is separated), in such a way that the drum (here including the active drum a or the long drum B) located on the second conveying unit 2 is brought into front-rear engagement, eliminating a large gap existing between the rear end portion of the long drum B and the front end portion of the source drum a, thereby enabling the maximum use of the cutting action of the cutter 4, the cutter 4 can perform the continuous cutting action, avoiding the situation that the cutter 4 is empty due to the large gap, thereby realizing the continuous cutting action of the cutter 4 (i.e., the time difference of any two cutting actions is equal), thereby realizing continuous high-efficiency production and ensuring the quality of the finished product reel a3 obtained by cutting.
In addition, as the distance between the cutting cutters 3 and 4 is an integral multiple of the length value of the finished product reel a3 formed by cutting by the cutting cutters 4, no extra paper segments are generated on the reels cut by the cutting cutters 4, and when any two contacted long reels B on the second conveying unit 2 are conveyed to the cutting cutters 4, the second conveying unit 2 does not need to stop and the cutting cutters 4 do not need to act, so that one cutting action is saved until the front end of the long reel B positioned at the rear is beyond the rated length of the cutting cutters 4, the second conveying unit 2 stops and the cutting action is performed by the cutting cutters 4.
By further describing the working principle of the inventive solution with reference to specific embodiments,
the working principle of continuous cutting head and tail and cutting of the winding drum of the embodiment is as follows:
as shown in fig. 3, step one: the reels are arranged on the first conveying unit 1 at equal intervals along the axial direction, and the source reels A are conveyed towards the cutting knife 3 one by one through the first conveying unit 1;
as shown in fig. 4 and fig. 5, step two: the front end portion of the source roll a is conveyed to the front holding member 51 with the first conveying unit 1, the front holding member 51 temporarily grips the front end portion of the source roll a, and the cutting blade 3 cuts the head end portion a1 of the source roll a; after the head end a1 is completely cut off, the front holding member 51 releases the source reel a to enable the source reel a to continue to be conveyed forward along with the first conveying unit 1, and simultaneously, the front end of the source reel a pushes the cut head end a1 to fall from the blanking gap 100;
referring to fig. 6, step three: the cut source reel A is driven by the first conveying unit 1 to be conveyed and moved forward towards the second conveying unit 2 and gradually transferred to the second conveying unit 2, and then the source reel A is conveyed and moved forward under the combined action of the first conveying unit 1 and the second conveying unit 2;
referring to fig. 7 and 8, step four: the front end part of the source roll A positioned on the second conveying unit is gradually conveyed and moved forward to the slitting cutter 4, after the source roll A is conveyed and moved forward along with the second conveying unit 2 to jump over the rated length of the slitting cutter 4, the slitting cutter 4 acts to slit the source roll A to obtain a required finished roll a3, the slitting cutter 4 continuously repeats the slitting action to slit the source roll A in sections, simultaneously with the first conveying unit 1 and the second conveying unit 2, the tail end part of the source roll A is gradually separated from the first conveying unit 1 to be conveyed until the tail end part of the source roll A is conveyed and moved forward to the tail holding member 52, the tail holding member 52 temporarily holds the tail end part of the source roll A, and the slitting cutter 3 acts to slit the tail end part a2 of the source roll A to form a long roll B, wherein the slit tail end part a2 is pushed by the front end part of the next source roll A to fall from the blanking gap 100; the long winding drum B at the moment is conveyed and moved forward to the position of the slitting cutter 4 through the second conveying unit 2 to perform continuous segmentation cutting action;
further, as shown in fig. 9, in the step three, in the process of gradually transferring the source roll a from the first conveying unit to the second conveying unit 2, the first conveying unit 1 accelerates the conveying speed to accelerate and advance the source roll a so as to accelerate and catch up the long roll B previously transferred to the second conveying unit 2 on the second conveying unit 2, thereby bringing the leading end surface of the source roll a into contact with the trailing end surface of the long roll B, and then the first conveying unit 1 slows down the conveying speed to be conveyed at the same speed as the second conveying unit 2.
The continuous cutting and cutting processing of the winding drum is realized by circularly repeating the steps, and the connecting and cutting method has the advantages of high efficiency, high yield and the like.
Embodiment two:
referring to fig. 10, in the present embodiment, compared with the first embodiment, the distinguishing feature is that the movable clamping dies 512 of the front holding member 51 and the rear holding member 52 of the present embodiment are each provided with a telescopic spring, the elastic force of the telescopic springs is utilized to make the movable clamping dies 512 and the fixed clamping dies 511 have an elastic normally closed structure, so that the movable clamping dies 512 and the fixed clamping dies 511 form an elastic annular channel, and the diameter of the formed annular channel is slightly larger than the diameter of the spool (in actual production, the diameter width of the annular channel is larger than 1-2mm of the spool, so that the spool can smoothly pass through the annular channel); the annular channel is used for encircling the supporting winding drum to play a role in limiting the radial freedom degree of the winding drum, and the annular channel is always encircling to support the source winding drum A in the process that the source winding drum A is transferred to the second conveying unit 2 by the first conveying unit 1, so that the stability of the winding drum is guaranteed when the first conveying unit 1 is transferred to the second conveying unit 2, the head end a1 and the tail end a2 of the source winding drum A are sequentially arranged by the cutting knife 3, the elastic force formed by the telescopic springs at the moment is used as the reverse acting force of the cutting knife 3 on the impact force of the source winding drum to offset the impact force, and the problem that the cutting knife 3 cuts the source winding drum A to jump to cause uneven cuts is effectively avoided.
Embodiment III:
referring to fig. 11, in this embodiment, the distinguishing features are compared with the first embodiment: the front holding member 51 of the present embodiment is reciprocally translated back and forth in the roll conveying direction at the front (upstream) of the cutting point of the cutting blade 3, and the tail holding member 52 is immobilized at the rear (downstream) of the cutting point of the cutting blade 3, so that an increase or decrease in the gap between the front holding member 51 and the tail holding member 52 is achieved by the back and forth translation action of the front holding member 51 to be away from or close to the tail holding member 52.
Referring to fig. 12, in the present embodiment, when cutting the leading end portion of the source roll a, the front holding member 51 at this time is moved in advance in the direction approaching the cutting point so that the front holding member 51 is disposed adjacent to the tail holding member 52, and then the front end portion of the source roll a is subjected to a spacing stabilizing action by the front holding member 51 so that the cutting blade 3 cuts the leading end portion a1, and then the leading end of the source roll a pushes the cut leading end portion a1 down from the tail holding member 52 to the blanking gap 100 between the second conveying unit 2.
As shown in fig. 13, in addition, during the gradual transfer of the source roll a toward the second conveying unit 2, the front holding member 51 is moved in a direction away from the cutting point to increase the gap between the front holding member 51 and the rear holding member 52 until the tail end portion of the source roll a is separated from the first conveying unit 1 and moved to the cutting point through the front holding member 51 for cutting.
As shown in fig. 14, when cutting the tail end portion of the source roll a, the tail end portion of the source roll a is subjected to limit stabilization by the tail holding member 52 (at this time, the front holding member 51 is moved in advance to a preset position away from the tail holding member 52), so that the cutting blade 3 is operated to drop the cut tail end portion a2 from the blanking gap 100 between the front holding member 51 and the tail holding member 52. Further, after the trailing end a2 is completely dropped, the front holding member 51 is moved and reset toward the trailing holding member 52 so that the front holding member 51 is brought close to the trailing holding member 52, and during the movement and reset of the front holding member 51, the front holding member 51 may be moved and reset to a predetermined position together with the leading end portion of the next set of source rolls a conveyed by the first conveying unit 1 until the front holding member 51 is moved and reset to a predetermined position and the leading end portion of the source rolls a is over the cut point rated length, and then the front holding member 51 cooperates with the cutter 3 to cut the leading end portion a1 of the source rolls a, and the above-described operations are repeated in a cycle.
In this embodiment, the front holding member 51 is utilized to reciprocate back and forth on a single side, so that the tail end a2 can be directly dropped, and the tail end a2 does not need to be dropped together with the next head end a1 cut by the next group of source reels a by pushing action, thereby avoiding the obstruction of the conveying of the source reels a and the influence of the cutting stability due to the tail end a2 remaining on the front holding member 51 or the tail holding member.
Embodiment four:
referring to fig. 15, in this embodiment, the distinguishing features are compared with the first embodiment: the tail holding member 52 of the present embodiment is reciprocally translated back and forth in the roll conveying direction at the rear (downstream) of the cutting point of the cutting blade 3, and the front holding member 51 is immobilized at the front (upstream) of the cutting point of the cutting blade 3, so that the gap between the front holding member 51 and the tail holding member 52 is increased or decreased by the back and forth translation action of the tail holding member 52 to be away from or close to the front holding member 51.
Referring to fig. 16, in the present embodiment, when cutting the leading end portion of the source roll a, the leading holding member 51 at this time performs a spacing stabilizing action on the leading end portion of the source roll a at a position close to the cutting point, and the tail holding member 52 is moved in advance to a position away from the cutting point to a preset position, it is achieved that the gap between the leading holding member 51 and the tail holding member 52 is increased, so that the cutter 3 acts to drop the head end portion a1 obtained by cutting from the blanking gap 100 between the leading holding member 51 and the tail holding member 52.
Referring to fig. 17, in addition, after the head end a1 is completely dropped, the tail holding member 52 moves toward the front holding member 51 to be brought close to the tail holding member 52 before the restoration, and during the restoration movement of the tail holding member 52, the source roll a gradually jumps over the tail holding member 52 to be gradually transferred to the second conveying unit 2 until the tail end portion of the source roll a is separated from the first conveying unit 1 and moves to the cutting point through the front holding member 51 to be cut.
Referring to fig. 16 and 18, when cutting the tail end portion of the source roll a, the tail end portion of the source roll a is subjected to limit stabilization by the tail holding member 52 (at this time, the tail holding member 52 is moved in advance to a preset position near the cutting point), so that the cutting blade 3 is operated to cut the resulting tail end portion a2, and the tail end portion a2 is cut in the front holding member 51. The tail holding member 52 is then moved in a direction away from the cutting point, the gap between the front holding member 51 and the tail holding member 52 is increased, so that the front end of the next group of source reels a conveyed by the first conveying unit 1 is pushed to cut the tail end portion a2 in the front holding member 51 so as to fall from the blanking gap 100 between the front holding member 51 and the tail holding member 52, and then the next group of source reels a repeats the above-described operation of cutting the head end portion, wherein the next group of source reels a can fall by a short stroke pushing the tail end portion a2 due to the position of the tail end portion a2 cut in the front holding member 51 being adjacent to the end of the front holding member 51, reducing the conveying influence of the tail end portion a2 on the source reels a.
Fifth embodiment:
referring to fig. 19, in this embodiment, the distinguishing features are compared with the first embodiment: the front holding member 51 of the present embodiment is reciprocally translated back and forth in the roll conveying direction at the front (upstream) of the cutting point of the cutting blade 3, and the tail holding member 52 is reciprocally translated back and forth in the roll conveying direction at the rear (downstream) of the cutting point of the cutting blade 3, so that the gap between the front holding member 51 and the tail holding member 52 is increased or decreased by the back and forth translation action of the front holding member 51 and the tail holding member 5.
Referring to fig. 20, in the present embodiment, when the front end portion of the source reel a is cut, the front holding member 51 is moved in advance to a predetermined position near the cutting point and the tail holding member 52 is moved in advance to a predetermined position away from the cutting point, at which time there is a gap between the front holding member 51 and the tail holding member 52 for the head end portion a1 to be cut to fall, and the to-be-cut blade 3 is operated to drop the head end portion a1 from the front holding member 51 to the blanking gap 100 between the tail holding members 52.
In addition, after the head end a1 is completely dropped, the tail holding member 52 is moved to a position adjacent to the cutting point of the cutter 3 in the cutting point direction, and the front holding member 51 is moved to a predetermined position in the direction away from the cutting point, at which time the source roll a gradually jumps over the front holding member 51 and the tail holding member 52 and gradually transfers to the second conveying unit 2 until the tail end portion of the source roll a is separated from the first conveying unit 1 and moves to the cutting point through the front holding member 51 for cutting.
As shown in fig. 21, when cutting the tail end portion of the source roll a, the tail end portion of the source roll a is restrained by the tail holding member 52 (at this time, the tail holding member 52 is moved in advance to a preset position near the cutting point), so that the cutting blade 3 is operated to drop the cut tail end portion a2 from the front holding member 51 to the blanking gap 100 between the tail holding member 52. After the trailing end a2 is completely dropped, the front holding member 51 is moved and reset in the direction of the cutting point and the trailing holding member 52 is moved and reset in the direction away from the cutting point, and the front holding member 51 may be moved and reset together with the leading end portion of the next set of source rolls a conveyed by the first conveying unit 1 during the movement and reset until the front holding member 51 is moved and reset to the predetermined position and the leading end portion of the source roll a jumps over the rated length of the cutting point, and then the above-described operation of the front holding member 51 in cooperation with the cutter 3 is repeated to cut the leading end portion a1 of the source roll a.
By adopting the mode of the present embodiment, the head end portion a1 and the tail end portion a2 can automatically fall from the blanking gap 100 by gravity after cutting, and the conveying stability of the source reel a is improved.
In summary, by means of the dynamic holding members of the third, fourth and fifth embodiments, the feeding interval between the two sets of source reels a can be effectively reduced, thereby realizing efficient production. In addition, the front holding member 51 or the rear holding member 52 in the present application is configured with a telescopic cylinder for driving it to move transversely in the roll conveying direction, and the telescopic end of the telescopic cylinder is connected to the front holding member 51 or the rear holding member 52, thereby realizing the back and forth reciprocating movement, wherein, by adopting the telescopic cylinder and the connection driving manner, it is a conventional technical means for those skilled in the art, and a detailed description is not given here.
