After the handle tape is fed to a predetermined distance by the upper and lower press rollers, the handle tape is held by the pulling pincer 211 opened in advance, the pulling pincer 211 is closed after holding, and then the handle tape is pulled to the downstream side by the pulling pincer 211.

The specific structure of the pulling clamp 211 is as follows: the pulling clamp 211 comprises a base portion and a clamping portion, wherein the clamping portion is driven by a driving device and can be opened and closed, two ends of the base portion of the pulling clamp 211 are respectively connected with a flexible circulating bearing structure through connecting pieces, and the flexible circulating bearing structure is arranged on the outer side of the first supporting wallboard 208 and the outer side of the second supporting wallboard 210.

In this way, in the process of reciprocating the flexible circulating bearing structure, the traction clamp 211 can reciprocate in the guide rail, in order to enable the connecting piece of the base part for fixing the traction clamp 211 to pass through the first supporting wall plate 208 and the second supporting wall plate 210, a bow-arrow-shaped through groove structure is arranged between the upper guide block 209 and the lower guide block 207 in the vertical direction on the first supporting wall plate 208 and the second supporting wall plate 210, and the through groove structure is used for guiding the connecting piece, so as to guide the limit traction clamp 211 to reciprocate in a designated track.

The handle tape feed cut is described in detail below with reference to fig. 6: in fig. 6, the handle cutting and feeding mechanism 1 is shown, the conveying path of which is arranged on the right side, the handle turning and transferring mechanism 2 (the handle turning and transferring mechanism 2 is schematically illustrated) is arranged on the left side of the handle cutting and feeding mechanism 1, the end of the handle strip coil is found by a manual or automatic robot in the first step, and then the end is pulled to the position between the upper pressing roller 206 and the lower pressing roller 205 to be clamped, at the beginning, the handle cutting and feeding mechanism 1 is in a non-transferring position, namely, the linear driving mechanism 203 is in a non-extending position, and at the same time, the handle cutting and feeding mechanism 1 is far away from the handle turning and transferring mechanism 2, the upper pressing roller 206 and the lower pressing roller 205 are driven to rotate, so as to pull the front end of the handle strip, and at the moment, the pulling clamp 211 on the downstream side of the upper pressing roller 206, as the front end of the handle strip further advances, the front end of the handle strip enters the jaws of the pulling grip 211, at which time the feeding of the upper and lower press rollers is stopped, the jaws of the pulling grip 211 close and grip the handle strip (see fig. 7), then the pulling grip 211 pulls the handle strip downstream in a bow-arrow shaped path, and the upper and lower press rollers feed the handle strip synchronously, the movement of the upper and lower press rollers is coordinated with the movement of the pulling grip to ensure a reasonable tension of the handle strip (see fig. 8), it is worth mentioning here that, in an ideal state, since the feeding speed of the upper and lower press rollers is the same as the pulling speed of the pulling grip and the movement path of the pulling grip is bow-arrow shaped, the handle strip should also form a bow-arrow shaped structure, in actual operation, the handle strip is not distributed exactly in an arc shape during pulling, but since the path of the movement path of the pulling grip 211 is equal to the advancing distance of the handle strip, that is to say the length of the handle strap supplied, that is to say the reciprocating movement of the fixed stroke of the pulling tongs, ensures a fixed length transport of the handle strap, which can likewise be squeezed into a bow-arrow-shaped configuration when it is transferred onto the handle inversion transfer mounting means 2, because of the mutual squeezing of the arcuate guide plates, which theoretically corresponds to the actual length of the bow on the base, that is to say the length of the handle strap supplied each time. Thus, the fixed-length supply of the handle belt can be ensured more stably.

Next, the handle belt starts to be transferred, the driving rod of the linear driving mechanism 203 starts to stretch, namely, moves leftwards, and moves towards the handle overturning and transferring installation mechanism 2 at other stations, then the handle belt on the arrow-shaped guide surface of the base on the handle cutting and supplying mechanism 1 is extruded to the arc-shaped concave surface structure on the handle overturning and transferring installation mechanism 2, the arc-shaped concave surface structure corresponds to the arrow-shaped guide surface of the base on the handle cutting and supplying mechanism 1, and a narrow channel can be formed between the arc-shaped concave surface structure and the handle belt for extruding and accommodating the handle belt in the arrow-shaped structure.

Referring to fig. 9, the handle strip is held in compression and then needs to be cut by a cutter, which is fixed in the conveying direction for transversely cutting the handle strip, and is disposed at the downstream side of the upper and lower press rollers and at the upstream side of the pulling clamp, wherein the cutter is at a position closer to the lower and lower press rollers (relative to the pulling clamp), and the cutter transversely cuts the handle strip, which now becomes the handle, for facilitating subsequent further transfer and installation (see fig. 10), and the telescopic rod of the linear drive 203 is still in an extended state and remains stable while the jaws of the pulling clamp continue to maintain the clamped state.

Next, referring to fig. 11, in the case where the handle tape is pinched, the jaws of the pulling grip start to open to release the handle tape, and the handle tape does not fall or shift because the handle tape is pinched by the handle trim feeding mechanism 1 and the handle inversion transfer mounting mechanism 2.

Next, referring to fig. 12, the handle turning and transferring mounting mechanism 2 is provided with a handle strip holding device, which may be an air suction device, a clamping device, or other structures capable of holding the handle strip, and the handle turning and transferring mounting mechanism 2 holds the handle strip. The telescopic rod of the linear driving mechanism 203 starts to contract, at this time, the handle cutting and supplying mechanism 1 is far away from the handle overturning and transferring installation mechanism 2, and the handle strip is separated from the handle cutting and supplying mechanism 1 at this time.

Next, with reference to fig. 13, the pulling grip 211 in the open position performs a return movement, back to the initial position close to the cutting blade, awaiting further transport of the next handle strip, at which point the single cycle is completed.

It should be noted that the handle strip is held by the upper and lower pressing rollers and the pulling clamp before being cut, so that the handle strip does not fall off due to the orientation and layout thereof in the whole conveying process, and because the front end of the handle strip is pulled and the rear end is tensioned and held, the handle strip can be normally conveyed regardless of the installation position of the handle cutting and feeding mechanism 1 and is not influenced by gravity.

After the handle strip is cut, the handle strip is kept by the traction clamp and the handle overturning and transferring installation mechanism 2 and can not fall off.

Therefore, the entire supply of the handle band is efficient and stable.

And then continues with the next cycle.

Referring to fig. 27, the handle receiving and leveling mechanism 3 will be described in detail, the handle receiving and leveling mechanism 3 includes an arc-shaped support plate 2006 having an upwardly convex arrow shape which fits the arc-shaped surface of the handle mounting arc 803 in one-to-one correspondence, the arc-shaped support plate 2006 is provided with a rectangular through hole 2007, and the rectangular through hole 2007 communicates with a side surface of the handle mounting arc 803 which is located on the downstream side of the conveying direction of the perforated gummed paper sheet 2001, wherein the communicating side surface is the downstream side and the non-communicating side surface is the upstream side, the conveying direction of the perforated gummed paper sheet 2001 is directed from the non-communicating side surface to the communicating side surface, and the rectangular through hole 2007 corresponds to the position of the opening on the perforated gummed paper sheet 2001 and allows passage of the lifting fork, below the perforated gummed paper sheet 2001 is provided with a conveying guide rod 2002 for supporting the perforated gummed paper sheet 2001, the conveying guide rod 2002 is located on the outer side of two ends of the arc-shaped bearing plate 2006, a floating piece 2003 is further arranged below the perforated gummed paper plate 2001, the floating piece 2003 is arranged on a floating sliding piece 2004 in a lifting mode, the floating sliding piece 2004 is installed on the bearing base 2005 and can slide left and right and be driven, a channel is formed between the bearing base 2005 and the arc-shaped bearing plate 2006, the perforated gummed paper plate 2001 is allowed to pass through, and precisely, the perforated gummed paper plate 2001 is located between the conveying guide rod 2002 and the arc-shaped bearing plate 2006.

Wherein the fork walls of the lifting fork should be provided with wear-resistant, low-friction structures, for example with a smooth surface. In this case, the lifting fork can smoothly drive the handle strip to be straightened downwards due to the rolling of the first troweling wheel 3001 when the lifting fork descends, the handle strip can be kept not to ascend due to the fact that the first troweling wheel 3001 is static and cannot rotate when the lifting fork ascends, and the lifting fork is more easily separated from the handle strip due to the smooth surface arranged on the fork wall.

Further, describing the floating function of the floating mechanism, referring to fig. 28, when the lifting fork transfers the handle tape, the first floating wheel 3001 and the second floating wheel 3002 are spaced a small distance from the lower surface of the perforated gummed paper sheet 2001, after the lifting fork is lifted, the first floating wheel 3001 and the second floating wheel 3002 are driven to be lifted and attached to the lower surface of the perforated gummed paper sheet 2001 and are engaged with the lower surface of the arc-shaped support plate 2006 to prepare for pressing of both ends of the handle tape, the floating mechanism formed by the first floating wheel 3001 and the second floating wheel 3002 is two left and right, and starts to press both ends of the handle tape toward both ends, thereby attaching both ends of the handle tape to the lower surface of the perforated gummed paper sheet 2001 through the connecting member, and then the two floating mechanisms of the left and right are restored to original positions, finally completing the installation of the handle tape, and after the installation of the perforated gummed paper sheet 2001 is transported to the downstream side, and entering the next step of processing.

The whole handle strap installation process is further described in one cycle:

referring first to fig. 30: wherein the abscissa is the rotation angle of the turntable rotation shaft 401 and the ordinate is the ventilation condition of the corresponding vent hole. Wherein high indicates that it is on to provide negative pressure and low indicates that it is not on to provide no negative pressure. It should be noted that the cycle diagram is not a timing diagram of operation, there is a pause in the actual rotation of the turntable rotating shaft 401, and the negative pressure through the turntable rotating shaft 401 can also be controlled by the vacuum generator.

The first step is as follows: step of feeding

When the handle tape transfer is started, the connection is performed according to the vacuum tube connection manner shown in fig. 20a, and the handle tape transfer installation components 705 in the handle turning transfer installation mechanism 2 are arranged according to the positions of the left side, the upper side, the right side and the lower side.

And the handle inversion transfer mounting mechanism 2 is at rest at this time, and the handle strap transfer mounting assembly 705 is also at rest.

1. When the single-station feeding scheme is adopted, as can be seen from fig. 20a and 30, the first vent hole has already started to enter the suction state, and since the first vent hole has a circumferential width, suction is started when it is just before 0 °.

At this time, the right hand-strap transfer module 705 connected to the first vent hole has sucked air (since the vent hole has only one half, the negative pressure is relatively small, but the suction of the hand strap is ensured), and the lower hand-strap transfer module 705 connected to the fourth vent hole has finished sucking air (since the vent hole has only one side, the negative pressure is relatively small, but the suction of the hand strap is ensured).

At this point, the handle strip supply operation is performed, see fig. 5, with the pulling pincer in the operating position, awaiting the delivery of the handle strip.

Shown in fig. 6 is the handle cutting and feeding mechanism 1 arranged on the right side, the end portion of the handle strip roll is found by a manual or automatic robot, and then the end portion is pulled between the upper pressing roller 206 and the lower pressing roller 205 to be clamped, and at the beginning, the handle cutting and feeding mechanism 1 is in a non-transfer position, that is, the linear driving mechanism 203 is in a non-extended position, and at the same time, the handle cutting and feeding mechanism 1 is away from the handle turning and transferring mounting mechanism 2, the upper pressing roller 206 and the lower pressing roller 205 are driven to rotate, thereby pulling the front end of the handle strip, and at this time, the pulling clamp 211 located on the downstream side of the upper pressing roller 206 and the lower pressing roller 205 is in an open state, and as the front end of the handle strip further advances, the front end of the handle strip enters the clamp jaws of the pulling clamp 211, at this time, the feeding of the upper pressing roller and the lower pressing roller is stopped, then the pulling tong 211 pulls the handle strip to the downstream side according to a bow-arrow shaped path, and the upper and lower press rollers synchronously feed the handle strip, the movement of the upper and lower press rollers is coordinated with the movement of the pulling tong so as to ensure reasonable tension of the handle strip (see fig. 8), it is worth explaining that, under ideal conditions, because the feeding speed of the upper and lower press rollers is the same as the pulling speed of the pulling tong and the movement path of the pulling tong is bow-arrow shaped, the handle strip should also form a bow-arrow shaped structure, in actual operation, the handle strip is not completely distributed according to an arc in the process of being pulled, but because the path of the movement path of the pulling tong 211 is equal to the advancing distance of the handle strip, namely the feeding length of the handle strip, namely the reciprocating movement of the fixed stroke of the pulling tong can ensure fixed-length feeding of the handle strip, when it is transferred to the handle turning and transferring mounting mechanism 2, the handle strip can also be squeezed into a bow-arrow shaped structure due to the mutual squeezing of the arc-shaped guide plates, and theoretically, the length of the bow-arrow shaped handle strip, that is, the supply length of the handle strip each time, is equal to the actual length of the bow-arrow shape on the base. Thus, the fixed-length supply of the handle belt can be ensured more stably.

Next, the handle belt starts to be transferred, the driving rod of the linear driving mechanism 203 starts to stretch, namely, moves leftwards, and moves towards the handle overturning and transferring installation mechanism 2 at other stations, then the handle belt on the arrow-shaped guide surface of the base on the handle cutting and supplying mechanism 1 is extruded to the arc-shaped concave structure on the handle installation arc-shaped piece 803, the arc-shaped concave structure corresponds to the arrow-shaped guide surface of the base on the handle cutting and supplying mechanism 1, and a narrow channel can be formed between the arc-shaped concave structure and the handle belt for extruding and accommodating the handle belt in the arrow-shaped structure.

Next, referring to fig. 12, the telescopic rod of the linear driving mechanism 203 starts to contract, the handle cutting and supplying mechanism 1 is far away from the handle turning and transferring installation mechanism 2, the handle belt is separated from the handle cutting and supplying mechanism 1 at this time, and the handle belt is sucked and fixed because the handle mounting arc 803 on the handle turning and transferring installation mechanism 2 is in a suction state.

Next, referring to fig. 32a, the handle installation arc 803 at the right station sucks the handle strip, then the handle installation arc 803 at the right side rotates clockwise by 90 ° in the whole process, the handle installation arc 803 at the right side continuously sucks the handle strip and moves to the lower side position, the handle installation arc 803 at the upper side position moves to the right side position, then the handle installation arc 803 at the lower side position moves downward and keeps the air suction state, and then the handle installation arc 803 moves to form a squeezing channel with the arc support plate 2006, and the handle strip is squeezed between the two, and then the handle installation arc 803 at the right side station is seen in the case of fig. 32 b.

Next, referring to fig. 32c, the handle strap installation is broken down into a plurality of steps, step a, temporarily stopping all vent holes from being ventilated, since the handle strap is squeezed and held at this time, so that no negative pressure needs to be provided, and at this time, the handle installation arc 803 of the right station has not yet started to transfer the handle strap, and temporarily no ventilation is needed; the lifting fork moves downwards, two ends of the handle belt are brought into and penetrate through the rectangular through hole of the arc-shaped supporting plate 2006, one side of the handle belt is contacted with the first leveling wheel 3001, the other end of the handle belt is contacted with the side face of the lifting fork, and the first leveling wheel 3001 can move in a single direction at the moment, so that the handle belt can slide downwards more easily; step b, when the handle belt completely enters, the lifting fork starts to rise to restore the original position, and at the moment, the first troweling wheel 3001 cannot rotate, so that the handle belt is kept at a fixed position, and the handle belt is prevented from being brought back by the lifting fork; and c, the first leveling wheels 3001 at the two ends respectively move upwards to press the handle belt, and then move towards the two sides respectively, namely the first leveling wheel 3001 on the left side moves leftwards, and the first leveling wheel on the right side moves rightwards, so that the effects of leveling the handle belt and adhering the lifting and collecting belt on the paperboard are achieved. Step d, the first troweling wheel 3001 on the left side moves towards the right side and then moves towards the lower side to return to the original position, the first troweling wheel 3001 on the right side moves towards the left side and then moves towards the lower side and returns to the original position, the handle belt is successfully installed on the paperboard at the moment, step e, the handle installation arc-shaped piece 803 rises to move back to the original lower side position, the handle installation arc-shaped piece 803 leaves a larger gap at the moment, and the paperboard provided with the handle belt is conveyed outwards according to the paper surface vertical to the drawing 32 c.

Referring next to fig. 32d, the handle attachment arc 803 in the right and lower positions of the open-air switch is now open to air, and the next cycle of handle strap transfer installation begins with the now right handle attachment arc 803.

2. When adopting three station feeds, the air vent is opened this moment in whole, and the difference of this feed scheme and simplex position feed scheme mainly lies in the three station simultaneous feed in left side, upside, right side, then need set up the switch of ventilating of four independent control handle installation arc 803 this moment to more nimble control.

The efficiency of the three-station feeding installation is higher than that of the single-station feeding installation.

Wherein, three handle cutting and supplying mechanisms 1, the left side, the upper side and the right side of the handle cutting and supplying mechanisms 1 feed simultaneously, and the handle belt is transferred to the handle installation arc-shaped piece 803 simultaneously, at the moment, four on-off valve structures for independently controlling the air suction on-off of the left side, the upper side, the right side and the lower side of the handle installation arc-shaped piece 803 are arranged, when the handle belt is transferred from the handle cutting and supplying mechanisms 1 to the handle installation arc-shaped piece 803, the left side, the upper side and the right side of the handle installation arc-shaped piece 803 have a negative pressure function to adsorb the handle belt and feed the handle belt, see figures 33a-33b, then the whole belt pasting rotating disc 603 is rotated by 90 degrees, see figure 33c, at the moment, the upper side, the right side and the lower side of the handle installation arc-shaped piece 803 has the handle belt, the rotation of the belt pasting, after waiting for the lifting fork to penetrate into the handle belt and the first troweling wheel to squeeze and mount the handle belt onto the paperboard, the negative pressure of the handle mounting arc 803 on the lower side is independently stopped, see the left-to-right flow chart of fig. 33c, so that the handle mounting arc 803 on the lower side is lifted and returned to the original position, then the handle mounting arc is rotated 90 degrees clockwise, at this time, the handle mounting arc 803 on the right side and the lower side is provided with the handle belt, the above-mentioned mounting of the handle belt is performed again, see fig. 33d, then the handle mounting arc 803 on the lower side is rotated 90 degrees clockwise, at this time, only the handle mounting arc 803 on the lower side is left to be provided with the handle belt, the mounting of the handle belt is performed for the third time, see fig. 33e, after waiting for the completion of the mounting, the handle mounting arc 803 on the lower side is lifted and.
