Description

  According to the present invention, in a bag making machine, a continuous backing provided with a handle string is cut into a predetermined length by a cutter into a handle piece, and the handle piece is attached to a portion of the bag body to which the handle piece is adhered. The present invention relates to a handle cutting / transferring device that transfers a product to a vertical transporting unit that transfers the product.

  In a conventional handle cutting and transferring apparatus, a continuous backing sheet provided with a handle string (hereinafter also referred to as “continuous backing sheet”) is traversed downstream on the handle cutting and transferring apparatus, and the leading end thereof passes through a cutter unit, and a cutter is provided. The blades of the propeller-like fingers are rotated from above and pressed toward the upper surface of the vertical-feed table to push the tip, which has been laterally fed further downstream from the cutting position by the upper surface of the vertical-feed table, to the top of the propeller-like fingers. The length of the continuous backing paper that has been laterally fed to the downstream side from the cutting position by the cutter, with the blades and the vertical feed table protruded from the top of the table and sandwiched between the driving rollers provided, and the paper was laterally fed and pressed and pulled. When the length becomes the predetermined length, the continuous backing sheet is cut into a length of one predetermined length with a cutter (hereinafter referred to as "handle piece"), and this cut handle piece is The paper is fed horizontally while being sandwiched between the blades of the propeller-like fingers and the drive roller so as to be spaced from the leading end of the continuous backing paper, and is dropped on the upper surface of the vertical feed table. The tail of the piece is pressed toward the top of the vertical feed table, and the leading end of the continuous backing sheet that has been traversed downstream from the subsequent cutter and protruded is lifted by the paper lifting finger, so that the subsequent The end of the continuous backing was prevented from colliding with the buttocks of the previously cut handle piece. Then, the handle piece which has been fed horizontally and dropped on the vertical feed table has been pushed vertically on the vertical feed table in the direction orthogonal to the horizontal feed by the projection claws of the vertical feed chain. (See Patent Documents 1 and 2).

However, in this case, the handle piece falls down toward the upper surface of the vertical feed table by being pushed by the rotating paper pressing finger while the tip portion is carried from above the drive roller to the upper surface of the vertical feed table. It takes time for the bottom of the sheet to fall sufficiently, and when the production speed is increased, the trailing end of the subsequent continuous backing sheet that is lifted by the paper lifting fingers will drop sufficiently enough. Productivity did not increase because the buttocks of the handle pieces pressed by the paper holding fingers that did not collide.
In particular, the continuous mount is a thin, soft high-quality paper, etc., and the air resistance causes the delay of the trailing edge of the handle to follow the operation of the paper holding finger and the follow-up of the leading end of the continuous mount to the operation of the paper lifting finger. In the case where a delay occurs, or when there is a habit such as warpage or curl at the tip of the continuous backing sheet or the buttocks of the handle piece, the productivity was not improved.

  Further, the above-described conventional handle cutting and transferring apparatus is provided with a propeller-like finger and a drive roller for determining the drop timing of the handle piece, and a paper holding finger and a paper lifting finger for preventing collision between the handle piece and the continuous mount. Therefore, the device itself becomes large due to the complicated structure, and the adjustment is also complicated and difficult.

  Therefore, in order to solve this problem, after cutting a continuous backing sheet provided with a handle string into a short handle piece with a cutter, the handle piece discharged from the transport device is temporarily received by a receiving plate, and the receiving plate is removed. It rotates downward at regular intervals, and the handle pieces received by the receiving plate are dropped on the transport path that transports the transport device perpendicularly to the transport direction of the transport device, and are regularly arranged on the transport path at regular intervals. Further, there is known a handle cutting and transferring device which prevents the handle pieces from colliding with each other (see Patent Document 3).

  However, in this case, the receiving plate rotated downward cannot rotate upward until the free-falling handle piece passes through the receiving plate, so that the production speed could not be increased. Further, since the handle piece is dropped from the receiving plate rotating downward onto the transport path below, the free fall is large and the handle piece is not always operated in the same state and is unstable. Therefore, jamming (clogging) due to dropping of the handle piece to a position other than the predetermined position or the like is likely to occur, and productivity has not been improved.

  As described above, the step of dropping the handle piece is a cause that the production speed cannot be increased and a cause that the production is stopped due to jam (clogging). That is, the productivity was not increased.

Therefore, even when the continuous mount is a thin, soft high-quality paper or the like, or when the leading end of the continuous mount or the butt of the handle piece has a habit such as warpage or curl, production can be performed without any problem. Speed can be increased .
In further addition, the handle cutting transferring device of the present invention, since it is composed of a conveyance of the horizontal direction only, it is easy construction and adjustment.

M, a pinch roller 6, a drive roll 6 ', a delivery belt 8, and a string aligning finger 42 for removing the twist of the handle string S. Paper guides 10, 10a, 10b, 10c, and 10e are provided between the rolls and the belt.

  The above-described components of the handle cutting and transferring apparatus of the present invention are all mechanically connected and driven. Alternatively, a single drive motor provided at each portion may be driven synchronously via a controller (not shown).

  FIG. 1 shows a continuous backing 11 provided with a handle string S, and a handle piece 12 obtained by cutting the continuous backing 11 to a predetermined length P. Handle strings S are provided at equal intervals on the continuous mount 11, and in the handle strings S provided on the continuous mount 11, the distance (pitch) between one end and the other end of one handle string S in the lateral feed direction is set. ) Is (1/2) P. Section A, Section A ′ ... are inner sections ((1/2) P-S1) obtained by subtracting the thickness or diameter S1 of the handle string S from the pitch (1/2) P of the handle string S. is there. Section A, Section C, Section A ', Section C'... Are sections ((1/4) P + (1/2) S1) from both ends of the handle piece 12 to Section A.

  A continuous mount 11 provided with a handle string S is manufactured by a handle manufacturing device (not shown) disposed upstream of the handle cutting and transferring device of the present invention, and the payout roll of the handle cutting and transferring device of the present invention shown in FIG. It is sent to 37-38. The continuous backing paper 11 transferred from the feeding rolls 37-38 in the transverse feeding direction is sandwiched by the first pulling rolls 1-1 'and transferred in the transverse feeding direction, and then sandwiched by the second pulling rolls 2-2'. Transported in the horizontal feed direction.

  The first pulling roll 1-1 'is composed of a lower roll 1' rotating at the same peripheral speed as the lower roll 37 of the feeding roll, and an upper roll 1 rotating reversely at the same peripheral speed as the lower roll 1 'via a gear or the like. Be composed. On the circumference of the upper roll 1, three semicircular relief grooves 43 straddling the handle string S provided on the continuous backing sheet 11 are arranged at three places so as to divide the circumference into three equal parts. The pulling roll 1-1 'holds the positions of the section A, the section A, the section Ua', the section A ', the section Ua ",... Of the continuous mount 11 shown in FIG. To rotate and transfer the continuous mount 11 in the lateral feed direction.

  The second pulling roll 2-2 'has a slightly higher peripheral speed than the lower roll 1' of the first pulling roll (for example, if the lower roll 1 'of the first pulling roll is 100%, the pulling speed is 100.05%, The lower roll 2 ′ rotates at a rate of 5/100% UP), and the upper roll 2 rotates reversely at the same peripheral speed via the gears and the like to the lower roll 2 ′. On the circumference of the upper roll 2, small-diameter portions having an arc length equal to each other for releasing the continuous mount 11 from being sandwiched across the handle string S provided on the continuous mount 11 are provided opposite to each other. Protrusions T1 and T2 having the same arc length for transferring the piece 12 are provided opposite to each other. Thereby, the second pulling roll 2-2 'holds one section of the handle piece 12 by sequentially sandwiching the positions of the section A, section A', section A "... Then, the continuous mount 11 is transported in the transverse direction by performing a half rotation with respect to the transfer of the minute. At the position of "a", the handle string S provided on the continuous mount 11 is sequentially straddled, and the continuous mount 11 is released from being held. In other words, the second pulling roll 2-2 'does not transfer the continuous backing sheet 11 in the horizontal feed direction at the position of the section "W", the section "W".

  The cutter 3 includes a rotary blade 3a provided on a cutter body 33 and a fixed blade 3b installed so as to make point contact from one end to the other end of the rotary blade 3a. The cutter 3 rotates the cutter body 33 once by synchronizing with the transfer pitch P of the continuous mount 11, and rotates the continuous mount 11 with the rotary blade 3 a and the fixed blade 3 b each time the cutter body 33 rotates once. Is cut at a predetermined length P. The cutter body 33 of the cutter 3 is configured to make one rotation when the continuous mount 11 is transported in the lateral feed direction by a predetermined length P of the handle piece 12 by the pay-out rolls 37-38.

  As shown in FIGS. 1 and 2, the second pulling roll 2-2 ′ is slightly rotated while sandwiching the downstream end of the section A of the continuous mount 11 between the convex portion T 1 of the upper roll 2 and the lower roll 2 ′. Then, since the peripheral speed of the second pulling roll 2-2 'is slightly higher than that of the first pulling roll 1-1', the peripheral speed between the first pulling roll 1-1 'and the second pulling roll 2-2' is increased. Tension is applied to the backing sheet 11 to eliminate slack. At this time, the cutter 3 cuts the continuous mount 11 at a predetermined position (the center of the section well ') so that the handle piece 12 has a predetermined length P. Simultaneously with this cutting, the semi-circular relief groove 43 on the circumference of the upper roll 1 of the first pulling roll is in a phase such that the handle string S provided on the continuous backing paper 11 does not straddle. The distance between -K is set.

  The cut handle piece 12 is held until the second pulling roll 2-2 'clamps and opens the upstream end of the section B of the handle piece 12 between the convex portion T1 of the upper roll 2 and the lower roll 2'. It is transported in the transverse direction. At this time, since the peripheral speed of the second pulling roll 2-2 'is slightly higher than the peripheral speed of the first pulling roll 1-1', the cut handle piece 12 is attached to the leading end of the subsequent continuous backing sheet 11. Is transported in the horizontal feed direction at a small interval, so that it does not collide with the leading end of the subsequent continuous mount 11. The arc length of the convex portions T1 and T2 of the upper roll 2 is preferably equal to or slightly shorter than the interval A, interval A ', interval A "... Of the continuous backing paper 11. The small-diameter portion for straddling the handle string S may have a cut shape as shown by a two-dot chain line.

  Also, at the downstream end of the section A, which is the tip of the cut handle piece 12, the second pulling roll 2-2 'is formed by the convex portion T1 of the upper roll 2 and the lower roll 2'. Before the upstream end is pinched and opened, it is clamped at the clamping start point L between the lower belt 7 and the upper belt 4 of the vertical feed belt 4-7-7 '. Then, the handle piece 12 is transported in the lateral feed direction by the vertical feed belt 4-7-7 ', hits the stopper M and stops. The peripheral speed of the upper and lower feed belts 4-7-7 'is higher than that of the second pulling roll 2-2', and the belt runs at, for example, 150 to 200% of the peripheral speed of the first pulling roll 1-1 '. Therefore, as shown in FIG. 3, when the handle piece 12 is transported in the transverse feed direction by the vertical feed belt 4-7-7 'and hits the stopper M and stops, the subsequent handle piece 12 and the handle An interval of one piece or more is provided.

  The stopper M is fixed on the paper guide 10a by a screw or the like, and the position of the stopper M in the lateral feed direction can be adjusted.

The upper roll 2 of the second pulling roll may have the same shape as the upper roll 1 of the first pulling roll, instead of the shape shown in FIG. In this case, the second pulling roll 2-2 'rotates while nipping the continuous mount 11 while straddling the handle string S in the escape groove 43 of the upper roll 2, and transports the continuous mount 11 in the lateral feed direction. When the cutter 3 cuts the continuous backing sheet 11 at a predetermined position (the center of the section waa '), the distance between I and K is set such that the upper roll 2 does not straddle the string S. .
In this case, the downstream end of the section a, which is the tip of the cut handle piece 12, is closed before the second pulling roll 2-2 'clamps and opens the upstream end of the section c of the handle piece 12. The lower belt 7 and the upper belt 4 hold the upper and lower feed belts 4-7-7 'at a holding start point L.

  As shown in FIG. 3, in the upper and lower feed belts 4-7-7 ′, the handle piece 12 has a lower belt 7 and an upper belt 4 on the upstream side in the vertical feed direction orthogonal to the horizontal feed direction of the handle piece 12. The handle string S is supported by the lower belt 7 ', and is transported in the lateral feed direction. The two lower belts 7 and 7 ′ are wound around two pairs of rollers 14 and 15 provided on the rotating shafts 18 and 21, respectively, and are driven by an input to a gear 25. The upper belt 4 is wound around rollers 16, 13 provided at the tips of side plates 22, 23 rotatable about a fixed shaft 19 and a roller 17 provided on the fixed shaft 19, and By gripping the provided gear 26 with a gear (not shown) of the rotating shaft 18, the mating surface of the lower belt 7 and the upper belt 4 does not slip, and the grip is held between the mating surface of the lower belt 7 and the upper belt 4. The piece 12 can be transported in the transverse direction. The screw 23 ′ of the side plate 23 is loosened, and the roller 13 is supported by the fixed shaft 19 as a fulcrum within a range where the gear 26 provided on the rotating shaft 20 of the roller 13 and the gear (not shown) of the rotating shaft 18 do not come off. By rotating and adjusting the vertical position, the contact pressure (clamping force) of the upper belt 4 with the lower belt 7 in the section from the roller 13 to the fixed roller 17 can be adjusted.

As soon as the handle piece 12 is transported in the horizontal feed direction by the vertical feed belt 4-7-7 'and hits the stopper M and stops, the operation immediately starts to transfer the handle piece 12 to the vertical transport section 9 via the transfer belt 8. .
First, in FIG. 2, the roller 16 provided at the end of the side plate 22 is rotated vertically by a rotation of the crank disk 5 via the turnbuckle 24 with the fixed shaft 19 as a fulcrum. At the same time, the roller 16 is transported in the feed direction, stops against the stopper M, and at the same time, the roller 16 provided at the tip of the side plate 22 rises, so that the handle piece 12 is released from the holding of the lower belt 7 and the upper belt 4. . That is, the downstream side of the upper belt 4 of the upper and lower feed belts 4-7-7 'is raised to release the handle piece 12 from being pinched. The phase of the crank disk 5 is adjusted such that the roller 16 provided at the tip of the side plate 22 rotates in the vertical direction with such a phase difference.
Next, in FIG. 4, the pinch roller 6 provided at the tip of the pinch roller lever 28 rotates the cam 27 that urges the pinch roller lever 28 with a spring 29 so that the pinch roller lever 28 comes into contact with the pinch roller 30. In order to move the handle piece 12 in the vertical feed direction orthogonal to the horizontal feed direction at the same time as the handle piece 12 is released from being sandwiched between the lower belt 7 and the upper belt 4 while rotating in the vertical direction. Then, the pinch roller 6 provided at the tip of the pinch roller lever 28 is lowered, and is pressed via the handle piece 12 against the drive roll 6 ′ located at a position downstream of the handle piece 12 in the vertical feeding direction. The phase of the cam 27 that contacts the pinch roller lever 28 is adjusted so that the pinch roller 6 descends with such a phase difference.
Then, the handle piece 12 sandwiched between the pinch roller 6 and the drive roll 6 ′ is transferred in the vertical feed direction and transferred to the delivery belt 8, and the transfer piece 8 transfers the handle piece 12 in the vertical feed direction. It is delivered to the vertical transport unit 9.
At this time, the speed at which the drive roll 6 ′ and the transfer belt 8 are transported in the vertical direction is, for example, 20% faster than the speed at which the vertical belt 4-7 ′ is transported in the horizontal direction. Collision with the following handle piece is prevented.
As shown in FIG. 5, a turnbuckle 24 ′ with a cam follower is connected to the end of the side plate 22, and the cam follower is urged by a spring 40 so as to contact the rotating cam 5 ′, and provided at the end of the side plate 22. The roller 16 may be rotated vertically about the fixed shaft 19 as a fulcrum.

The delivery belt 8 is composed of a pair of upper and lower feed belts, and two sets are provided at intervals in the horizontal feed direction. A string aligning finger 42 is provided between the transfer belts, and the handle string S nipped between the pair of upper and lower feed belts of the transfer belt 8 and transported in the vertical feed direction is rubbed by the string aligning finger 42, and By applying a tension to S in a direction opposite to the transfer direction, the twist of the handle string S can be removed.
The string aligning finger 42 is a collapsible pin, and is adjusted so as to fall down when it receives a certain force or more from the handle piece 12 or the handle string S. In addition, a triangular plate or the like (not shown) is used in addition to the folding pin. The triangular plate is low on the upstream side in the transfer direction and high on the downstream side. The handle string S rubs along the slope and climbs over the triangular plate, thereby applying tension to the handle string S in the direction opposite to the transfer direction. The twist of the handle string S can be removed. The triangular plate is moved up and down by a cam (not shown), moves to a position below the handle piece 12 when the handle piece 12 passes, so as not to interfere with the handle piece 12, and when the handle string S passes, the handle string S It is adjusted so that it can be moved to an upper position and rubbed against the handle string S to remove the twist of the handle string S. At least one string alignment finger 42 is provided, and preferably two at a distance in the transverse direction as shown in FIG.

When the handle piece 12 sandwiched between the pinch roller 6 and the drive roll 6 ′ is transported in the vertical feed direction and delivered to the delivery belt 8, the pinch roller 6 provided at the tip of the pinch roller lever 28 is raised, At the same time when the handle piece 12 is released from being pinched by the pinch roller 6 and the driving roll 6 ', the subsequent handle piece 12 is pinched by the lower belt 7 and the upper belt 4 of the upper and lower feed belts 4-7-7'. The roller 16 provided at the tip of the side plate 22 is lowered so as to be transferred in the feed direction. That is, the downstream side of the upper belt 4 of the upper and lower feed belts 4-7-7 'is lowered, and the subsequent handle piece 12 is nipped and transported in the horizontal feed direction. The phase of the cam 27 contacting the pinch roller lever 28 is adjusted so that the pinch roller 6 rises with such a phase difference, and the roller 16 provided at the tip of the side plate 22 has such a phase difference. The phase of the crank disk 5 is adjusted so as to descend.
Then, when the subsequent handle piece 12 is transported in the horizontal feed direction by the vertical feed belt 4-7-7 'and hits the stopper M and stops, the handle piece 12 is immediately transferred to the vertical transport unit 9 via the transfer belt 8. In order to start the transfer operation, the operation after paragraph 0029 is repeated again.

  In the vertical transport section 9, the handle piece 12 delivered from the delivery belt 8 is pushed by a pair of left and right chain feed claws 35 and transported in the vertical feed direction.

As described above, the handle cutting and transferring apparatus of the present invention cuts the continuous backing sheet 11 provided with the handle string S into the handle pieces 12 of the predetermined length by the cutter 3, and then the conventional handle cutting and transferring apparatus. Unlike the device, there is no step of dropping the handle piece when the transfer direction changes from the horizontal feed direction to the vertical feed direction, and it is delivered from the cutter 3 to the vertical transport unit 9 without the step of dropping the handle piece. Even if the speed is increased, it does not collide with the leading end of the continuous backing sheet 11, and jamming (clogging) due to dropping to a position other than a predetermined position does not occur, thereby improving productivity.
Further, the grip piece 12 is always held between the second pulling roll 2-2 ', the upper and lower feed belts 4-7-7', the pinch roller 6, and the delivery belt 8, and is vertically transported only in the horizontal direction. Since it is delivered to the unit 9, the behavior is stable and the production speed can be increased. Therefore, even when the continuous backing 11 is a thin soft high-quality paper or the like, or when the leading end of the continuous backing 11 or the rear end of the handle piece 12 has a habit such as warpage or curl, the production can be performed without any problem. Speed can be increased.
Furthermore, the handle piece 12 from which the twist of the handle string S has been removed by the string aligning finger 42 provided between the transfer belts can be transferred to the vertical transport unit 9.
Furthermore, since the handle cutting and transferring device of the present invention is configured to be transported only in the horizontal direction, the structure and adjustment are simple.

  Note that a series of operation cycles of the above-described handle cutting and transferring apparatus of the present invention coincide with the rotation cycle of the cutter 3. As described in paragraph 0017, the motor may be driven by mechanical connection, or a single motor may be installed in each part and driven synchronously via a controller (not shown). When each part is driven synchronously by a single motor, the sensor 53 shown in FIG. 2 detects the handle piece 12 shortly before it hits the stopper M, and then drives the drive motors 51 and 52 of the crank disk 5 and the cam 27. It can be configured by synchronizing with the speed of moving the upper and lower feed belts 4-7-7 'in the horizontal feed direction and driving with the above phase difference.

  In the above-described series of operations of the handle cutting and transferring apparatus of the present invention, the operations described as simultaneous may be adjusted so that the operations overlap within an allowable range. For example, even after the handle piece 12 is transported in the horizontal feed direction by the vertical feed belt 4-7-7 'and hits the stopper M and stops, the handle piece 12 is sandwiched between the lower belt 7 and the upper belt 4. In this state, the lower belt 7 and the upper belt 4 continue to rub against the surface of the handle piece 12, so that the surface of the handle piece 12 and the contact portion with the stopper M are damaged or jammed (clogged). As described in paragraph 0029, the handle piece 12 is moved in the lateral feed direction, hits the stopper M, and stops at the same time as described in paragraph 0029, because paper and paper dust are generated and the lower belt 7 and the upper belt 4 are worn. It is preferable that the handle piece 12 is released from the holding between the lower belt 7 and the upper belt 4, but even if the handle piece 12 is held between the lower belt 7 and the upper belt 4 within an allowable range. good. That is, the operations may be adjusted so as to overlap within an allowable range.
