Description

In the present invention, in the bagging process of instant noodles and foods, powdered or liquid soup, kayak such as dried vegetables, confectionery and seasoning oil, freshness preservatives, drying materials and the like are packaged on the instant noodles and foods. The present invention relates to a pouch loading device for loading pouches.

Conventionally, in a continuous packaging pouch, a strip-shaped resin material or a mixed material film is folded back in the width direction, and the other side in the width direction of the folded portion is sealed with a vertical seal to form an internal space, and then the contents are stored in the internal space. , A plurality of packaging parts (small bags) are divided and formed by horizontal seal parts. The pouch loading device is a device that cuts this continuous packaging pouch (continuous packaging body) from the horizontal seal portion, divides it into each pouch, and loads it into a predetermined packaging container or the like (see Patent Document 1).

(Arrangement of units)
In the conventional pouch loading device, the roll for feeding the continuous pouch, the accumulator (weight roll) for holding, the top roll, and the roller guide (upper) pass through the pitch detector (with width guide), and the lower roller guide. From (bottom), it is introduced into a cutter unit (guillotine type) via a feed roll, cut into small bags, and the small bags are put into the chute (miscut detection position).

An example of the pouch loading device has an interval of 216 (mm) from the top roll position to the pitch detection position, 108 (mm) from the pitch detection position to the feed roll center, and 52 (mm) from the feed roll center position to the cut position. Further, the chute entrance was 35 (mm) below the cut position.

(Pouch running guide)
The roller guide on the lower side of the top roll and the roller guide on the upper side of the feed roll are used to position the continuous packaging pouch in the width direction.

There is a pitch detection unit in the middle position of the upper and lower roller guide units, and in this part there is a loosely regulated guide in the thickness direction of the pouch.

(Structure of cutter unit)
The cutter uses a guillotine type cutter that presses the blade surface of the lower blade against the blade surface of the upper blade with a spring force and moves it simultaneously in the left-right symmetrical direction to perform shear cutting.
(Miscut detection)

An optical miscut detection sensor for confirming the lateral seal edge on the tip side of the leading pouch is placed one pitch below the pouch from the cut position.
Regarding pitch detection, Patent Document 2 describes an ultrasonic pitch detector.

Japanese Unexamined Patent Publication No. 2004-10107 JP-A-2007-10353

In the food industry, the number of women and foreign workers is increasing due to the remarkable labor shortage and the retirement of skilled workers due to aging. As the number of unskilled workers increases, there is a demand for equipment that does not stop at a small scale and does not require time for maintenance.

The factor that most reduces the productivity of the conventional pouch throwing device is miscut (cutting body). When the body is cut off, the operation is restarted, so it is necessary to clean the contents attached to the parts and the machine will stop for a long time. In addition, there is a small stop (hereinafter referred to as "chocolate stop": it is not a serious accident, but the machine needs to be stopped for checking) due to a small stop such as miscut, pitch abnormality, miscut false detection, etc., which also reduces productivity. .. Considering the current working environment and the demands of the food packaging industry, it is required to realize a device that does not cut the body and is less likely to cause chocolate stoppage when putting in sachets.

The conventional pouch throwing device has the following problems (1) to (6).

(1) Prevents transport clogging due to the bending habit of the horizontal seal, and prevents miscutting.
The distances from the center position of the feed roll to the cutter position and the chute inlet position are 52 (mm) and 87 (mm), respectively. When a continuous package pouch with a pitch shorter than these lengths has a bending habit in the horizontal seal part, when the horizontal seal part passes through the center position of the feed roll, there is no guide to keep the pouch straight, so from the bending habit position The continuous packaging pouch at the tip can be tilted.

Due to this inclination, the tip of the continuous packaging pouch interferes with the parts at the cutter inlet portion and the chute inlet portion, causing clogging of transportation. In particular, when the next pouch is sent into the clogged chute portion, the horizontal seal portion of the continuous packaging pouch may not reach the cut position and may be cut off.

(2) Eliminate miscuts when cutting the bending position due to the bending habit of the lateral seal part.
When a horizontal seal part with a bending habit comes to the cut position, if the horizontal seal part at the cut position is bent in a large "<" shape in the direction of travel of the lower blade, when the cutting edge collides with the bent part The lower blade escapes downward due to the resistance of the blade, and the clearance becomes large, resulting in poor cutting (uncut).

(3) Improve pitch detection accuracy and prevent miscuts.
Conventionally, there is only a roller guide installed above and below the pitch detection position and a guide that gently regulates the continuous packaging pouch at the pitch detection position in the thickness direction. There is a degree of freedom in the direction. For this reason, when the continuous packaging pouch gets over the top roll, the pitch is caused by the fluttering due to the conspicuous polygonalization of the unevenness with a large difference between the diagonal length and the opposite side length, and the tension fluctuation due to the jump of the weight roll in the accumulator box. Since the pouch at the detection position moves in the thickness direction, the detection becomes unstable and the pitch detection accuracy can vary. This is considered to be the cause of miscut.

(4) Prevent overrun from the top roll and prevent miscut (cutting).
When the intermittent transportation of the continuous packaging pouch is stopped, the top roll is dragged by the inertia of the pouch weight and the rotation does not stop for a while. Due to this rotation, the wound pouch is fed toward the pitch detector in excess of the predetermined transport amount. Therefore, at the measurement point of the pitch measuring instrument, the stop position of the pouch shifts in the traveling direction from the feed amount determined based on the pitch measurement, and at the next pitch feed, the pouch is fed more than the predetermined pitch amount at the cutter position. The seal position can be misaligned. This is considered to be the cause of miscut.

(5) Eliminate miscut false positives due to bending habits.
The miscut sensor consists of a set of upper and lower optical detectors, and detects "insufficient feed, proper feed, and over feed". If the horizontal seal portion including the tip edge has a bending habit, the position of the tip edge of the horizontal seal portion of the pouch hanging from the miscut sensor position changes depending on the bending angle. For this reason, it may be determined that the feed is insufficient even though the feed is normal, or that the feed is normal even though the feed is excessive. For this reason, the miscut sensor causes chocolate stop (abnormal feed stop) and body cutting in the continuous packaging pouch that has a habit of breaking.

(6) Easily attach the cutter blade.
Because it is difficult to adjust "optimal accuracy for vertical surface alignment (within 3/100 (mm) gap between upper and lower surfaces)" with a flat blade of a guillotine type cutter blade, and "parallelism of V-groove and contact angle with cutting edge" with a wave blade. If adjusted by an unskilled worker, it is difficult to maintain the cutting performance, which causes premature wear and cutting defects.

In the conventional pouch loading device, in order to prevent miscut (body breakage) due to the bending habit of the horizontal seal portion, there is also a method of printing a mark between the packaging portions of the continuous packaging pouch as described in Patent Document 1. Not only does it take time for the user to print a mark on the packaging material, but it cannot prevent clogging at the cutter entrance or chute entrance due to a bending habit, or miscut (body breakage) due to this.

In addition, a bending habit correction device (the resin-based packaging material is stretched by the heat in the chamber) may be used, but a separate purchase cost and installation space are required, and depending on the characteristics of the packaging material, the bending habit can be completely removed. It is difficult to modify and is not suitable for heat-affected contents.

The present invention solves the problems listed in (1) to (6) above without using a mark printing or a bending habit supply device, and even if there is a bending habit, it can be conveyed without clogging at the cutter entrance or the chute entrance. It is an object of the present invention to provide a pouch loading device that can cut even if there is a bending habit at the cutting position.

In the present invention, a continuous packaging pouch in which a plurality of packaging portions are partitioned by a horizontal sealing portion is detected from a top roll through a pitch detector to detect the pitch between the horizontal sealing portions, and introduced into a cutter unit via a feed roll. It is a pouch throwing device that cuts into each pouch and throws it into the chute. The dimension from the center of the feed roll to the entrance of the chute is formed to be shorter than one pitch, and the continuous packaging pouch is curved in the length direction during transportation. , Equipped with a transport guide that regulates movement in the thickness direction and width direction, the detection position of the pitch detector matches the nip position of the feed roll, and the cutter unit is a parting cut method consisting of a saw blade and a receiver. It is a pouch throwing device.

In the present invention, it is preferable to shift the supply speed of the continuous packaging pouch according to the position of the dancer roll provided on the entry side of the top roll.

In the present invention, it is preferable to increase the apparent transport outer diameter of the top roll.

In the present invention, it is preferable that the top roll is wound with a round belt.

In the present invention, the continuous packaging pouch has a folded pouch on one side and a vertical seal on the other side in the width direction, and each pouch is partitioned by a horizontal seal portion. The transport guide guides the continuous packaging pouch in the width direction and the thickness direction by the folding side guide and the vertical seal side guide, and the folding side guide is attached to the feed roll in the width direction of the continuous packaging pouch. It is preferable that they overlap.

In the present invention, it is preferable that the miscut detector is installed in the middle of the chute, and the miscut detector is an ultrasonic sensor capable of detecting the boundary.

In the present invention, in the cutter unit, the two thin plates constituting the receiver have a gap, and the saw blade can enter the gap. It has a structure in which the lateral seal portion is cut off by advancing into the gap of the pinching saw blade, and it is preferable to provide a stripper on the front surface of the gap so that the lateral seal portion after cutting can be eliminated even if it slips into the gap. be.

According to the pouch loading device of the present invention, the dimension from the center of the feed roll to the entrance of the chute is shorter than one pitch, so that the transport is not clogged due to the bending habit and the body is not cut off. Further, by providing the transport guide and matching the detection position of the pitch detector with the nip position of the feed roll, the pitch measurement accuracy is improved and miscutting is less likely to occur.

Further, since the cutter unit adopts a parting cut method composed of a saw blade and a receiver, even if there is bending due to a bending habit, the seal can be easily pierced and miscut is not performed. Further, since it is not necessary to adjust the sliding of the blade surfaces of the lower blade and the upper blade, the blade replacement work can be completed in a short time even if the operator is not a skilled worker.

In an embodiment, the supply speed is changed according to the position of the dancer roll provided on the entry side of the top roll so that the transport tension (determined by the weight of the dancer roll) is constant even if there is acceleration / deceleration of intermittent transport. There is no fluttering and pitch detection accuracy is improved.

Further, as another embodiment, by increasing the apparent transport outer diameter of the top roll, the pitch measurement accuracy is improved by transporting the top roll without fluttering over, and slip or overrun due to roll inertia to the cutter portion. Since there is no deviation in the feed amount, there is an effect of preventing miscuts (displacement of the cut position of the horizontal seal part, body cutting).

As yet another embodiment, by using an ultrasonic sensor capable of detecting the boundary as a miscut detector, even if the lateral seal portion is bent due to a bending habit, the boundary between the seal and the content portion is detected, so that the influence of bending is obtained. It can produce excellent effects such as being able to correctly detect the miscut position without being affected.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

As shown in FIGS. 1 to 2, in the pouch loading device, the continuous packaging pouch 1 in which a plurality of packaging portions (pouches) 1a are partitioned by the horizontal sealing portion is passed through the pitch detector 11 from the top roll 4 to the horizontal sealing portion 1b. The continuous packaging pouch 1 that detects the pitch between the pouches and passes through the pitch detector 11 is a pouch loading device that is introduced into the cutter unit 12 via the feed roll 8 and cut into each pouch and charged into the chute 16. .. In addition, in FIGS. 1 and 2, the continuous package pouch 1 is shown by a chain double-dashed line, and FIG. 13 shows the pouch 1a and the horizontal seal portion 1b.

As shown in FIGS. 1 and 2, the pouch loading device forms the dimension from the center of the feed roll 8 to the inlet of the chute 16 to be shorter than one pitch, and is curved in the length direction during the transportation of the continuous package pouch. A transport guide 5 that regulates movement in the thickness direction and the width direction is provided, the detection position of the pitch detector (pitch detection unit) 11 is matched with the nip position of the feed roll 8, and the cutter unit 12 is the saw blade 13 and the receiver 14. It is a parting cut method composed of.

The pouch loading device has a structure extending from the transfer roll 2 to the top roll 4, the feed roll 8, the cutter unit 12, the pitch detector 11 to the chute 16 on the front side of the main body. Further, a cover (not shown) for covering the cutter unit 12, the pitch detector 11, and the chute 16 is provided. Further, a touch panel type operation panel 30 as a control unit is provided on the side portion of the main body. In the main body, the mechanical case is independent of the electrical case. Further, the chute 16 has a configuration in which the width can be changed according to the width of the continuous packaging pouch by operating the chute width adjusting knob 21. A miscut detector 17 that detects a miscut of a pouch is arranged with the detection center of the chute 16 as a detection area. In FIG. 3, the chute 16 shows a state in which the minimum width is adjusted to the maximum width by the alternate long and short dash line.

The detailed configuration of the pouch loading device will be described.
[Transportation standard]
(1) As shown in FIG. 1, the transport standard of the continuous packaging pouch 1 is based on the width center of the pouch 1a (see FIG. 13). One side of the continuous packaging pouch 1 in the width direction is folded back, and the other side is the vertical seal side. In FIGS. 1 and 3, the folded side is on the right side and the vertical seal side is on the left side.

(Action of transport standard)
(1) When changing the width of the pouch 1a, as shown in FIG. 1, adjust the transport guides 5 (vertical seal side guide 6, folded side guide 7) on both sides with reference to the center of the width.
(2) As shown in FIG. 2, since the feed roll 8 nip the vertical seal of the continuous packaging pouch 1 and convey the feed roll 8, the position of the feed roll 8 is also adjusted according to the pouch width.

(Effect of transport standard)
(1) When the pouch loading device of the embodiment is incorporated into a pillow wrapping machine whose transport standard is the center of the pouch width, it is not necessary to change the set position of the device even if the pouch width is changed.
(2) The pitch detector 11 aims at the central position of the pouch 1a and detects it. In the conventional machine, the position of the detector was changed by changing the pouch width, but this machine does not need to change the position.

[Transfer roll 2]
(Structure of carry-in roll 2)
The continuous packaging pouch 1 is introduced to the entry side of the top roll 4 via the transfer roll 2 and the dancer roll 3.
(1) The carry-in roll 2 has a configuration in which round bars 2a are arranged at equal intervals on the circumference (indicated by the alternate long and short dash line 2c).
(2) In the transfer roll 2, a silicone tube is extrapolated from the outer circumference of the round bar 2a.
(3) A variable speed motor is used to drive the rotation of the transfer roll 2.

(Action of transfer roll 2)
(1) The transfer roll 2 supplies the continuous packaging pouch 1 to the pouch loading device. (2) The rotation speed of the transfer roll 2 is changed by the position of the dancer roll 3 (detecting the angle of the dancer lever 3a).
(3) High-speed supply is possible when the dancer roll 3 is above the horizontal (reference numeral 3au), and low-speed supply is possible when the dancer roll 3 is below the horizontal (reference numeral 3ad).

(Effect of transfer roll 2)
(1) The continuous packaging pouch 1 wrapped around the lower half of the dancer roll 3 does not separate from the dancer roll 3. In case of jumping or oversupply, prevent the dancer roll 3 from being separated from the dancer roll 3 due to the hanging of the continuous packaging pouch 1).

(2) Since the continuous packaging pouch 1 is wound on a round bar having a large friction coefficient by a silicone tube in a pseudo-polygonal state, it exhibits a large pulling ability (similar to the prior art).

[Intermediate pool]
The intermediate pool between the transfer roll 2 and the top roll 4 will be described. Since the feed roll 8 intermittently conveys the continuous packaging pouch 1, an accumulator element is required to match the speed of the continuously supplied pouches. As an accumulator element, the pouch throwing device is provided with a dancer roll 3 as an intermediate pool.

(Composition of intermediate pool)
(1) A rotation fulcrum is provided at one end of the dancer lever 3a, and a dancer roll 3 is formed at the other end.
(2) The dancer roll 3 can freely rotate (up and down) around the rotation fulcrum of the dancer lever 3a.

(3) An angle detection sensor is provided on the rotation axis of the dancer lever 3a. (4) The continuous packaging pouch 1 is passed through the inlet roll of the top roll 4 with the dancer roll 3 underneath from the carry-in roll 2. ..

(Action of intermediate roll)
(1) Due to the difference between the supply speed (rotation of the transfer roll 2) and the take-out speed (rotation of the feed roll 8), the dancer roll 3 moves up and down around the rotation fulcrum with reference to a substantially horizontal position.
(2) The dancer roll 3 moves downward at "supply speed> take-out speed" and moves up at "supply speed <take-out speed".

(3) Since the feed roll 8 on the take-out side performs intermittent transport (acceleration-constant speed-deceleration-stop), if the supply speed is constant (for example, the average speed of intermittent transport), during "acceleration-constant speed" The dancer roll 3 rises to the upper limit position and descends to the lower limit position during "deceleration-stop".
(4) As for the tension of the continuous package pouch 1, the take-out speed rapidly accelerates at high speed, so the upward acceleration of the continuous package pouch wound from the lower side of the dancer roll 3 exceeds 1 G, and the dancer roll 3 jumps. The tension is loosened, and at the upper limit position of the dancer lever 3a, the line of the continuous packaging pouch is stretched to increase, and at the lower limit position, the continuous packaging pouch 1 is loosened downward from the dancer roll 3 and the tension is lost.

(5) At the start of intermittent transport of the feed roll 8, when the transport speed> the supply speed and the dancer roll 3 moves above the horizontal position, the angle detection sensor (not shown) incorporated in the rotation axis of the dancer lever 3a detects the rise. However, by increasing the transport speed, the dancer roll 3 is prevented from jumping.
(6) When the intermittent transfer of the feed roll 8 is stopped, the transfer speed <the supply speed, and when the dancer roll 3 moves below the horizontal position, the angle detection sensor incorporated in the rotation axis of the dancer lever 3a detects the descent. By reducing the transport speed, the continuous packaging pouch 1 is prevented from separating from the dancer roll 3.

(Effect of intermediate roll)
(1) By changing the supply speed of the carry-in roll, the continuous packaging pouch 1 wound around the underlay does not separate from the dancer roll 3, and the transport tension of the continuous packaging pouch 1 is the same as that of the dancer roll 3. It becomes a constant tension based on the weight.
(2) By making the tension from the top roll 4 to the feed roll 8 constant, fluctuations in tension due to intermittent transport are suppressed, and fluttering of transport is eliminated.

[Top roll 4]
(Structure of top roll 4)
(1) The top roll 4 is composed of four small-diameter guide rolls. (2) The line in which the continuous packaging pouch 1 is wound around the four small-diameter guide rolls (4a) can be regarded as the outer circumference of the roll having a large radius.
(3) When the pouch is heavy, the round belt is wound around the round belt set groove 18 processed on the guide rolls at the inlet and the outlet to resist the free rotation of the roll.

(Action of top roll 4)
(1) Change the transport direction of the continuous packaging pouch 1 from "bottom to top" to "top to bottom".
(2) When a continuous packaging pouch in which a plurality of packaging portions are partitioned by a horizontal sealing portion is wound around a roll, the intermediate portion between the packed packaging portion and the horizontal sealing portion has a large bending rigidity, so that the horizontal sealing portion has a large bending rigidity. It has the property of bending flexibly at the starting position of. When the pitch between the horizontal seal portions is larger than the radius of the roll, the continuous packaging pouch wound around the upper semicircle of the roll bends the start position of the horizontal seal portion to form an apex, and the packaging portion is sided. It becomes a hexagonal shape to an octagonal shape with large irregularities.
(3) In this state, if the patrol pouch is transported, it will get over the roll while maintaining a square shape with large irregularities, so the transport line will move by the difference between the diagonal length and the opposite side length on the outlet side, and the front surface. Shaking (transportation fluttering) occurs from side to side when viewed from the viewpoint.
(4) The top roll 4 has a large number of vertices so that the transport line becomes a pseudo large-diameter roll outer circumference by combining a plurality of rolls, and the wound continuous packaging pouch 1 smoothly follows the outer circumference. Make a polygon with inconspicuous unevenness.

(5) By using a small-diameter roll for the top roll 4, the inertia of the roll itself becomes small, and it is easy to rotate when the pouch transport is started (the resistance of roll rotation is small, and it slips due to the friction of the wound pouch surface. Rotates immediately without stopping), and stops immediately when stopped (free rotation due to the inertia of the roll stops immediately due to the frictional resistance of the wrapped pouch).
(6) When the pouch is heavy, even if the transport of the continuous pouch stops decelerating, it tends to move downward due to its inertia. By wrapping the round belt around the roll, it becomes a resistance to the free rotation of the roll, and at the same time the deceleration stops, the rotation of the roll also stops, and there is no extra feeding.

(Effect of top roll 4)
(1) Since the top roll 4 has a smooth polygon along the outer circumference, the transfer fluttering at the pitch detector 11 position due to the difference between the diagonal length and the opposite side length due to the polygon having few vertices and conspicuous unevenness occurs. Can be prevented.
(2) Since the top roll 4 has a small roll inertia, it can immediately follow the start / stop of the pouch transport and stop the rotation, so that the rotation stop of the roll does not affect the transport tension.

(3) The round belt prevents free rotation due to the inertia of the pouch weight and does not generate extra feed.
(4) Pitch measurement accuracy is improved by transporting without fluttering, and since there is no deviation in the amount of feed to the cutter unit 12, there is an effect of preventing miscuts (displacement of the cutting position of the horizontal seal portion, body cutting).

[Transport guide 5]
(Structure of transport guide 5)
(1) As shown in FIGS. 1 and 3, the transport guide 5 has independent transport guides 5 (vertical seal side guide 6, folded side guide 7) on the vertical seal side and the folded side of the continuous packaging pouch 1. , The length is several times as long as the pouch pitch (2 to 4 times as long in the embodiment) continuously in the pouch feeding direction.
(2) The vertical seal side guide 6 is continuous from the lower part of the top roll 4 to the position directly above the feed roll 8. The guide shape has a V-shaped notch and a groove 6a into which the seal portion enters the bottom thereof.

(3) The folded-back side guide 7 is continuous from the lower part of the top roll 4 to the vicinity of the lower half of the diameter of the feed roll 8. The guide shape has a V-shaped notch.
(4) The vertical seal side guide 6 is the length to the position immediately before contacting the outer diameter of the feed roll 8, while the folded side (front side of the device) guide 7 is up to the lower half of the feed roll 8. (Longer than the vertical seal side). The vertical seal side guide 6 has a different length from the folded side guide 7 (the position of the lower end is different).

(5) By the transport guide width adjusting knob 19, the vertical seal side guide 6 and the folded side guide 7 of the transport guide 5 move evenly to the left and right (in the width direction of the continuous packaging pouch) in the symmetrical direction with respect to the transport center. When using the continuous packaging pouches 1 having different widths, the distance between the transport guides 5 is adjusted by the adjustment knob 19.

(Action of transport guide 5)
(1) Since the vertical seal side guide 6 and the folded side guide 7 of the transport guide 5 guide the vertical seal side and the folded side of the continuous packaging pouch 1 in a shape that follows the shape, the range in which the transport guide 5 is configured. (From the lower part of the top roll 4 to the 8 parts of the feed roll), the continuous packaging pouch 1 is restricted from moving in the left-right direction when viewed from the front, and can be conveyed in a stable posture without fluttering or twisting. In addition, since the curvature in the transport direction is also regulated, the apparent pitch will not be shorter than the regular length.
(2) Even if there is an overrun from the top roll 4, the transport guide 5 continuously guides both the vertical seal side and the folded side of the continuous packaging pouch 1 along the transport direction to provide sliding resistance. Since there is an effect of restricting buckling such that the lateral seal portion is zigzag in the thickness direction, it is difficult for excess feed to enter the transport guide 5.

(3) As shown in FIG. 4, the horizontal seal detection position of the continuous packaging pouch of the pitch detector 11 substantially coincides with the center position of the diameter of the feed roll 8, and the vertical seal of the continuous packaging pouch is the feed roll at that position. The nip is fixed by 8, and the folded-back portion is regulated by the V-shape of the folded-back side guide 7, and the posture is determined without shifting in the thickness direction and the width direction.

(Effect of transport guide 5)
(1) When the pitch is detected, the pouch does not flutter and the posture is constant, so that the detection is stable and the variation in the measurement pitch is reduced (it can be fed to the cutter at an accurate pitch).
(2) Since excessive feed due to overrun can be suppressed, it is unlikely that the pitch detection position of the pitch detector 11 will be fed in excess of the feed amount of pitch measurement (pitch position deviation).

(3) Since there is sliding resistance due to the continuous guide to the continuous packaging pouch 1 by the transport guide 5, overrun occurs without the brake of the holding plate applied by air pressure (without causing pinholes). No transport is possible.

[Feed Roll 8]
(Structure of feed roll 8)
(1) The feed roll 8 has a structure in which a vertical seal of a continuous packaging pouch 1 is sandwiched between a metal roll 9 having an outer diameter of φ32 (diameter 32 (mm)) and a rubber-wrapped roll 10 and nip-conveyed.
(2) The metal roll 9 is on the fixed side, and the rubber roll 10 is on the pressurizing side due to the spring force.

(3) As shown in FIG. 4, the nip position A of the feed roll 8 is a position where the outer peripheral surfaces of the metal roll 9 and the rubber winding roll 10 are in contact with each other. Approximately the center position of the diameter of the feed roll 8 (the center of the diameter of the metal roll 9 and the diameter of the rubber winding roll 10 and on the line connecting the respective rolls 9 and 10 axes) is the nip position A, and the nip position A Is the detection point of the pitch detector 11.
(4) By reducing the outer diameter of the feed roll 8, the distance from the center position (nip position) A of the diameter of the feed roll 8 to the cut line position B could be brought closer to 27 (mm).

(5) The transfer by the feed roll 8 is intermittently driven by the servomotor drive.
(6) The feed roll 8 is configured on a slide mechanism, and the entire feed roll 8 is moved back and forth by the adjustment knob 20 (based on the center of the pouch width). As shown in FIG. 3, the position of the feed roll 8 can be adjusted by the adjustment knob 20 so that the feed roll 8 is located at the position 8w at the maximum width (1w) of the continuous packaging pouch 1 and is located at the position 8s at the minimum width (1s). ..

(Action of feed roll 8)
(1) If there is a crease in the horizontal seal that will be the next cut position immediately after the head is cut, the pouch pitch will be 52 (mm) in the conventional dimension between the nip roll and the cutter (52 (mm)). If it is less than, when the weight of the hanging pouch is lost, a bending moment due to a bending habit acts on the straight pouch, and the tip of the continuous packaging pouch can be tilted.
(2) When the tip side horizontal seal position becomes equal to or larger than the opening width of the cutter portion due to the inclination of the continuous package pouch, the tip side horizontal seal interferes with the cutter opening at the same time as the continuous package pouch is conveyed, causing clogging. Also, even if it passes, it may get stuck at the shoot entrance.
(3) In the present embodiment, the vertical seal is fixed to the nip at the position 27 (mm) above the cut position, and the folded side is guided in a V shape to a position substantially the same as the nip position A. Therefore, as shown in FIG. 9, when the downstream side seal of the pouch fixed to the nip is just in the cut position, even if the upstream side side seal has a habit of breaking, it is 34 (mm) to the chute entrance. Therefore, if the pouch pitch is 40 (mm) or more, the continuous packaging pouch 1 is held as a nip on the downstream side (lower side) from the position of the horizontal seal portion having a bending habit, and at the same time, the folded side is in the V-shaped guide. Therefore, the tip of the pouch on the downstream side of the feed roll 8 does not tilt until it reaches the chute inlet.

(Effect of feed roll 8)
(1) Even if the horizontal seal portion 1b, which is the next cut position of the new leading pouch after the leading pouch of the continuous packaging is cut, has a habit of breaking, from the nip position of the feed roll 8 to the entrance of the chute 16. He keeps his posture straight without being affected by his bending habits.
(2) Even if the horizontal seal part has a crease, the pouch 1a immediately after cutting does not tilt, so the tip of the pouch interferes with the inlet parts of the cutter or the chute inlet during transportation, resulting in clogging. Cutting failure due to inclination (In the conventional guillotine type cutting method, the cutting force is easily transmitted straight to the pouch when the pouch hangs vertically, but if there is an inclination, the cutting force works in the direction of releasing the blade and cutting failure occurs. It becomes easier to do), and the decrease in productivity due to the choco stop of the machine can be improved.

[Pitch detector 11]
(Structure of Pitch Detector 11)
FIG. 5 is an explanatory view around the feed roll 8, the cutter unit 12, and the pitch detector 11. The stripper 15 described later is not shown.
(1) In a standard pouch (mostly pitch 40 (mm) or more), an ultrasonic pitch detector 11 is placed on the upstream side within 1 pitch (27 (mm)) from the cut position. ing.
(2) As shown in FIGS. 4 and 5, the pitch detector 11 detects the boundary between the seal and the content portion at approximately the center position A of the diameter of the feed roll 8 (the position where the vertical seal of the continuous packaging pouch is nipped). do. The pitch detector 11 is of an ultrasonic type, and as shown in FIGS. 4 and 5, the transmitting means 11a and the receiving means 11b are arranged on the transport path of the continuous packaging pouch with the position A sandwiched from the thickness direction. ing.

(3) At the time of detection, the vertical seal of the pouch is fixed to the nip by the feed roll 8, and the folded side is held in position by the V-shaped notch (see FIG. 3) of the transport guide 7 (the upstream side of the detector is the pitch). More than the length, the downstream side is guided by a V-shaped notch in a range of 12 (mm)).

(Action of pitch detector 11)
(1) As shown in FIG. 9 and the like, the width direction and the thickness direction of the continuous packaging pouch 1 are regulated so that the positions do not change by the nip fixing by the feed roll 8 and the transport guide (folding side guide 7). Therefore, the detection is stable and the variation in measurement accuracy is small.
(2) Also, in the transport direction, the distance from the lower position of the top roll 4 to the pitch detector 11 position is several times longer than the pouch pitch, and this distance is regulated by the transport guide 5, so that the pouch 1a It can be accurately conveyed without being affected by the pitch error caused by the decrease in apparent length due to bending habits and curvature.

(3) When the fixed quantity feed based on the pitch measurement result is completed, the feed roll 8 stops rotating and holds the pouch as a nip. Therefore, even if there is an overrun of the pouch from the top roll 4, the feed roll 8 The pouch does not shift in the transport direction at the detection position at the same position as the center position A of the diameter, and the measurement data of the pouch length by the boundary detection and the transport amount match.

(Effect of pitch detector 11)
(1) By improving the pitch measurement accuracy, the amount of transportation to the cutter unit 12 becomes accurate, and the cut position deviation (miscut) is reduced.

(2) If the lateral seal portion to be cut next has a bending habit, the continuous packaging pouch will be in a bent state from the bending habit position after this has passed through the feed roll 8. Even if there is such an inclination of the continuous packaging pouch, the cut position B is reached by sending only 27 (mm) after the boundary position is detected, so that the arrival position deviation of the horizontal seal at the cut position is very small. No miscut occurs because the allowable value of the cut position deviation is 2 (mm) or less.
As the pitch detector 11, various types such as an ultrasonic type and an optical type can be used.

[Cutter unit 12]
(Structure of cutter unit 12)
FIG. 6 is a view of the periphery of the cutter unit 12 as viewed from below as indicated by the arrow U in FIG. The stripper 17 is not shown in FIGS. 5 and 6. 7 (a) is a view from the L direction of FIG. 5, (b) is an explanatory view of the feed roll 8 and the periphery from the cutter unit 12 to the chute 16 from the front, and FIG. 8 is a chute 16 below the cutter unit 12. It is a downward view.
(1) As shown in FIGS. 5 and 6, in the cutter unit 12, the saw blade 13 and the receiver 14 are indicated by a crank mechanism (the crankshaft of the saw blade 13 is indicated by a reference numeral 13 Ck, and the crankshaft of the receiver 14 is indicated by a reference numeral 14 Ck. The drive mechanism of the crankshaft is reciprocated in symmetrical directions (not shown), and the lateral seal portion of the continuous packaging pouch 1 is sandwiched between the saw blade 13 and the receiver 14 to cut off. As shown in FIG. 6, the continuous packaging pouch 1 can be cut according to various widths and sizes, and the smallest continuous packaging pouch 1 is indicated by reference numeral 1s and the maximum continuous packaging pouch 1 is indicated by 1w. The position of the feed roll 8 can also be moved in the width direction correspondingly, and the feedol position for niping the vertical seal portion of the smallest continuous package pouch corresponds to the code 8s, and the feed corresponding to the vertical seal of the largest continuous package pouch. The roll corresponds to the reference numeral 8w.

(2) The saw blade 13 is a saw-shaped blade in which roughly V-shaped cutting edges 13a are arranged at equal intervals in a large number of width directions.
(3) The saw blade 13 is incorporated with a slight inclination in the traveling direction (a shear angle is provided so that the cutting edge 13a abuts on the lateral seal portion in order).
(4) The receiver 14 has a configuration in which two thin plates have a gap of saw blade thickness + α (α = 1 (mm) in the embodiment).
(5) The cutting edge shape of the saw blade 13 is such that the upper surface side of the blade becomes a pointed tip and tapers toward the lower surface side, and when the saw blade advances, the cutting edge on the upper surface side first becomes the horizontal seal portion 1b of the pouch. Hits.
(6) It is preferable that the abutting position is close to the lower surface of the upper plate of the receiver 14.
(7) This increases the resistance that the lateral seal portion 1b sneaks between the lower surface of the upper plate of the receiver and the upper surface of the saw blade, and reduces the elongation of the lateral seal portion 1b (see FIG. 13) when piercing. This is to make it easier to cut.

(8) When the saw blade 13 penetrates between the receivers 14, the gap between the cutting edge position of the saw blade 13 and the lower surface of the upper plate of the receiver 14 is important in order to realize the optimum parting condition. When mounting the saw blade 13, the mounting surface of the saw blade 13 and the receiver 14 has design dimensions in advance so that the optimum cut-off condition can be realized at any time with respect to the clearance height of the receiver 14. It is in the position determined by.

(9) A stripper 15 is configured to prevent the horizontal seal portion of the pouch after cutting from slipping into the gap of the receiver 14 (see FIGS. 7 and 8).
The stripper 15 is an elongated plate-shaped part that is configured at the central gap position of the chute 16 having a two-divided structure and extends in the transport direction of the continuous packaging pouch when viewed from the front.
As shown in FIGS. 7 and 8, a fine groove 14a is formed in the center of the receiver 14 of the cutter unit 12 in the width direction, and is arranged in the fine groove 14a as shown in FIG. 7B. The stripper 15 is arranged so that the length direction of the stripper 15 is orthogonal to the plane of the receiver 14. The thickness of the stripper 15 is smaller than the width of the U-shaped narrow groove 14a formed in the receiver 14 (see FIGS. 7 and 8). Further, the width of the stripper 15 seen from the front is such that the front end portion of the receiver 14 has a very slight gap from the left end portion of the stripper 15 width at the retracted stroke end position of the receiver 14, and the width is at the forward stroke end position of the saw blade 13. , There is a gap of 2 (mm) from the cutting edge to the right end of the stripper 15 width.

At the retracted position of the receiver 14, the stripper 15 protrudes outside the narrow groove 14a. At the forward end position of the receiver, the stripper 15 is completely inside the groove 14a.
The depth of the U-shaped narrow groove 14a provided in the receiver 14 is such that the U-shaped bottom portion of the receiver 14 does not collide with the stripper 15 at the forward stroke end position of the receiver 14. That is, the stripper 15 is configured at a position that does not interfere with the range of motion of the saw blade 13 and the receiver 14. Further, as shown in FIG. 7A, the receiver 14 can adjust the transport direction of the continuous packaging pouch and the angle with respect to the stripper 15. In this case, the receiver 14 swings around the narrow groove 14a where the stripper 15 is located so that the angle can be adjusted. FIG. 7A shows a state in which the receiver 14 shown by the solid line is perpendicular to the stripper 15 and a state in which the receiver 14 shown by the alternate long and short dash line is tilted.

The stripper 15 has a structure in which the tip on the feed roll 8 side has an R shape and a taper is provided on the approach side of the pouch to smoothly guide the stripper 15 to the chute 16.
Further, as shown in FIG. 7B, the stripper 15 is fixed to a fixture 15a such as two bolts. The fixture 15a is fixed to the central portion of the sliding guide shaft paired with the width adjusting screw constituting the width adjusting mechanism of the chute 16.

The length of the stripper 15 starts from a position appropriately protruding upstream from the meshing position of the cutter unit in the transport direction of the continuous packaging pouch 1, and extends to a surface position where the pouch of the chute 16 slides down. In the operating range of the cutting edge 13 and the receiver 14, both ends of the stripper 15 have a straight shape, and the guide is such that the pouch is fed by the feed roll 8 and enters the chute 16.
As shown in FIG. 8, the chute 16 is a width-adjustable type, and the stripper 15 is arranged at the center position of the chute 16 downward on the paper surface.

(10) There is a chute 16 inlet C at a position 27 (mm) from the center position A of the feed roll 8 to the cut line B and further 7 (mm) from the cut line B.

(Action of cutter unit 12)
(1) When the horizontal seal portion of the continuous packaging pouch 1 is in front of the gap of the receiver 14, when one of the approximately V-shaped cutting edges of the saw blade 13 collides, the horizontal seal portion 1b slips into the gap of the receiver 14. Due to the resistance, breakthrough occurs in the seal part. As the cutting edge advances, breakthroughs occur one after another, and when the full width breakthrough is completed, cutting is completed.

(2) The saw blade 13 and the receiver 14 are attached and fixed to their respective holders with bolts so as not to escape vertically, horizontally, front and back, and the force in the traveling direction of the saw blade 13 does not escape vertically and cuts. The state is always constant and the cutting force is kept at the maximum.
(3) Since the chute 16 inlet C is located at a position 34 (mm) from the center of the feed roll 8, if the pitch is 40 (mm) or more, the bending habit of the lateral seal portion passes through the center position of the feed roll 8. Occasionally, the tip of the tuplet pouch 1 is inside the chute 16 and the tip does not get caught in the entrance of the chute 16.

(4) The saw blade 13 and the receiver 14 cut off the horizontal seal 1b of the continuous packaging pouch 1 and the cut position is on the right side of the stripper 15 when viewed from the front. The upper end side horizontal seal of the cut top pouch may slip into the gap of the receiver 14 by this cut-off cut. If there is no stripper 15, the receiver 14 retracts with the leading pouch hanging, and a cutting defect (the cut pouch does not fall while being caught or the pouch falls timing is delayed) occurs.
With the stripper 15, even if the upper end side horizontal seal of the cut pouch 1a slips into the gap of the receiver 14, when the tip of the receiver 14 retracts to the right position in the width direction of the stripper 15, it slips into the stripper 15. The horizontal seals collide. When the receiver 14 is further retracted, the horizontal seal that has slipped in gradually moves toward the gap entrance side of the receiver 14 to come off, and the cut pouch falls. The falling pouch slides down into the chute 16 with the end face on the right side in the width direction of the stripper 15 as a guide.

(Effect of cutter unit 12)
(1) With the conventional guillotine type cutter blade, if the lateral seal part has a bending habit, the lower blade pressed by the spring force against the blade surface of the upper blade escapes, resulting in clearance and poor cutting. However, since the saw blade 13 is fixedly attached without escape, the saw blade 13 does not escape and always collides with the lateral seal portion under the same conditions, causing breakthrough and miscut due to the bending habit. Does not occur.

(2) Since the cutter unit 12 does not have a lifting part for the lower blade, the chute inlet can be brought closer to 7 (mm) from the cut position, and even if the lateral seal portion has a bending habit, the chute inlet C can be used. Eliminates clogging due to interference between the tip of the pouch and parts.
(3) The saw blade 13 and the receiver 14 can be attached to each of the attachment surfaces to realize the optimum parting condition, and the time-consuming sliding adjustment of the blade surfaces of the lower blade and the upper blade is not required. , Even if you are not a skilled worker, the blade replacement work can be completed in a short time.
(4) Even if the horizontal seal slips into the gap of the receiver 14, the pouch 1a always falls on the chute after cutting due to the action of the stripper 15.

[Miscut detector 17]
(Structure of miscut detector 17)
(1) As shown in FIG. 4, the inlet C of the chute 16 is located at a position 7 (mm) from the cutter center position B (27 (mm) from the center position A of the feed roll 8 to the cutter center position B). It is located at a position of 34 (mm) from the center A of the feed roll 8 to the chute entrance C).
(2) The miscut detector 17 uses an ultrasonic sensor, and its mounting position (detection position D) is a position of "pouch pitch length-seal length / 2" from the cutter position B. In FIG. 4, the detection position of the miscut detector 17 is the position indicated by reference numeral D. As shown in FIG. 4, the miscut detector 17 has a transmitting means 17a and a receiving means 17b, and becomes a detection position D on the ultrasonic transmission path from the transmitting means 17a to the receiving means 17b.
(3) Since the detection position of the miscut detector 17 differs depending on the pouch pitch, a position adjusting mechanism is provided.
(4) By using an ultrasonic detector for the miscut detector 17, the boundary between the seal portion and the content portion at the transport tip of the continuous packaging pouch 1 is detected.

(Action of miscut detector 17)
(1) As shown in FIG. 4, since the dimension from the center position A of the feed roll 8 to the chute inlet C is 34 (mm), the tip of the pouch having a pitch of 40 (mm) or more reaches the chute 16 inlet C. At that time, since the lateral seal portion having a bending habit is on the upstream side of the nip position A of the feed roll 8, the tip of the pouch is about to enter the chute opening straight without being affected by the bending habit. When the lateral seal portion having a habit of being bent reaches the nip position A of the feed roll 8, only 6 (mm) has entered the inside of the chute 16. Therefore, clogging does not occur at the inlet C of the chute 16.

(2) When the lateral seal portion having a bending habit passes through the center position of the feed roll 8 and the folding side guide 7 of the continuous packaging pouch 1 disappears, the tip of the continuous packaging pouch 1 can be tilted due to the folding habit.
(3) Even if the tip of the continuous packaging pouch 1 tries to tilt, the tip of the pouch enters the inside of the chute 16, and the tip of the pouch tilted to the slip surface or the upper guide surface of the chute 16 comes into contact with the chute 16, so that the tip of the pouch 1 tilts. Is restricted and guided inside the chute without getting caught.

(4) When the intermittent transportation of the pouch is completed, it enters the inside of the chute 16 by detecting that the boundary between the horizontal seal portion and the content portion of the leading pouch slightly passes the miscut detector 17 position. It can be determined that the pouch is normally transported without the tip being clogged in the middle, and that the central portion of the horizontal seal length is at the cut position.
In addition, after detecting the boundary position of the pouch, if it stops beyond the permissible range (the boundary position of the pouch exceeds the detection position by 2 (mm) or more), it is determined that the feed is excessive, and even if the transportation is completed, the boundary is reached. If the position is not detected, it is determined that the feed is insufficient. If it is over-fed or under-fed, the safe area in the center of the horizontal seal at the cut position cannot be cut or the contents may be cut, so a miscut alarm is issued and the cutting machine stops operating.

(5) In the conventional miscut detection, optical detectors are placed side by side at two places in the transport direction with an interval up and down, and the passage of the tip edge of the top horizontal seal of the pouch is confirmed. When the transfer of the pouch is completed, the range until the tip edge of the seal passes through the upstream side detector and reaches the downstream side detector is normally fed, and if it passes through the downstream side detector, it is overfed and upstream side detection. If the vessel has not been reached, it is judged that the feed is insufficient.
(6) If the tip of the pouch that has entered the inside of the chute 16 has a habit of bending and is bent in the lateral direction, the tip of the seal may be operated even though the transfer is completed normally and the cutter may be operated. In the optical detection method that detects, the detection judgment is that the tip of the seal is not fed enough, and the cutting machine is stopped by a "miscut alarm (alarm that the feed amount is insufficient for the pouch pitch and the contents are cut at the cut position)". do.

(7) If the tip of the seal bent sideways due to a bending habit is judged to be "normal position stop" by the optical detection method when the transfer is completed, the cutter will operate even if it is over-fed for some reason, and the pouch will operate. Miscut the contents (cut the body).
(8) On the other hand, the miscut detector 17 of the embodiment detects the boundary between the seal portion and the content portion of the transport tip of the continuous packaging pouch 1 by using the ultrasonic detector. .. Therefore, even if the horizontal seal part with a crease is cut and the horizontal seal part with a crease is transported as the head of the pouch by the next pitch feed, the boundary that is not affected by the fold is not the tip of the horizontal seal part. Since it is detected, the amount of transportation can be confirmed normally.

(Effect of miscut detector 17)
(1) By significantly shortening the distance from the feed roll 8 on the upstream side to the entrance of the chute 16 (34 (mm) in the embodiment) across the cut position B, the pitch exceeding this distance (40 (in the embodiment)). If the pouch is from mm) to 40 (mm) or more in the majority of standard pouches, it can be transported without clogging at the entrance of the chute 16 even if it has a habit of breaking.

(2) Instead of detecting the edge of the horizontal seal portion of the top pouch, the miscut detector 17 of the embodiment detects the boundary between the horizontal seal portion and the content portion by an ultrasonic detector, thereby detecting the top of the pouch. Miscut prevention can be detected without being affected by the bending of the seal due to the bending habit.

[Characteristic configuration of the pouch loading device according to the embodiment]
The pouch loading device according to the embodiment is characterized by the following configuration.
(1) The dimension from the center of the feed roll 8 to the entrance of the chute 16 is shorter than one pitch.
The diameter of the feed roll 8 is reduced (diameter φ32 (mm)), and the cutter unit 12 is cut off to reduce the unit thickness in the transport direction and at the same time reduce the protrusions on the upstream and downstream sides of the unit as much as possible. Therefore, the distance from the center position of the feed roll 8 to the cutter position was shortened to 27 (mm), and the distance from the cutter position to the chute entrance was shortened to 7 (mm). Due to these shortenings, the distance from the center position of the feed roll 8 to the entrance of the chute 16 is 34 (mm), which is within 40 (mm) of the minimum pitch of a standard pouch.

(2) A long transport guide 5 is provided to regulate the curvature in the length direction and the movement in the thickness direction and the width direction during the transport of the continuous package pouch.
The top roll 4 is a V-shaped transport guide 5 (seal side guide 6, folded side guide 7) (see FIG. 3) in which the vertical seal and the folded portion of the continuous packaging pouch 1 are matched to the cross-sectional shape viewed from the transport direction. It is continuously arranged from the lower side to a position near the feed roll 8 with a length several times as long as the pouch pitch.

(3) The detection position of the pitch detector 11 coincides with the nip position of the feed roll 8.
The installation position of the pitch detector 11 coincides with the vertical seal nip position (center position of the feed roll diameter) of the feed roll 8, and the folded-back side guide 7 of the transport guide 5 described in (2) is the lower end of the feed roll 8. It extends to near the position.

(4) The cutter unit 12 employs a parting-cutting method composed of a saw blade 13 and a receiver 14.
A saw blade 13 in which V-shaped blades are arranged at equal intervals and a receiver 14 composed of two plates having a gap face each other with a transport path for a continuous packaging pouch.
The saw blade 13 and the receiver 14 move in symmetrical directions by the crank mechanism, and the saw blade 13 penetrates into the gap of the receiver 14 to pierce and cut the lateral seal portion of the continuous packaging pouch 1.

The saw blade 13 is attached so that a plurality of V-shaped cutting tips have shear angles. The cross-sectional shape of the cutting edge of the saw blade has a pointed tip on the upper surface side of the blade and a taper toward the lower surface side. When the saw blade advances, the cutting edge on the upper surface side first abuts on the lateral seal portion 1b of the pouch (see FIG. 14). The abutting position is preferably close to the lower surface of the upper plate of the receiver 14. This is because the resistance that the lateral seal portion 1b sneaks between the lower surface of the upper plate of the receiver and the upper surface of the saw blade is increased, and the elongation of the lateral seal at the time of piercing is reduced to facilitate cutting.
The gap between the receivers 14 determines the magnitude of the resistance that the lateral seal portion 1b tries to slip into between the receivers.
The gap is set so that "piercing force"<"sneakingresistance".
With respect to the thickness of the saw blade 13, the distance between the receivers 14 = (thickness of the blade) + 1 (mm).
Straight cut: Saw blade thickness 1 (mm) / receiver spacing 2 (mm), Wave cut: Saw blade thickness 2 (mm) / receiver spacing 3 (mm)

(5) The supply speed is changed according to the position of the dancer roll 3.
There is a dancer roll 3 at the tip of the lever 3a supported by the rotation fulcrum, and the continuous packaging pouch 1 is wrapped around the underhang so as to support the dancer roll 3. Due to this configuration, the weight of the dancer roll 3 becomes the transport tension of the continuous packaging pouch 1.
Under intermittent transfer conditions, the supply speed of the transfer roll 2 is changed according to the position of the dancer roll 3 in order to keep the transfer tension constant, and the dancer roll 3 is always kept in a substantially horizontal position.

(6) Increase the apparent transport outer diameter of the top roll 4.
The top roll 4 is a top roll 4 composed of four small diameter rolls, and has a large apparent transport outer diameter.
Further, the top roll 4 may be wrapped with a round belt to provide rotational resistance.

(7) An ultrasonic sensor capable of detecting the boundary is used as the miscut detector 17.
The entrance of the chute 16 has a guide plate on the opposite side to the sliding surface, and the pouch 1a is attracted between them. Further, the miscut detector 17 is installed at a distance of "pitch of pouch 1a-seal length / 2" from the cut position, and the miscut detector 17 of the ultrasonic detector is used to connect the seal portion and the content portion. Detect the boundary position.

[Action due to the characteristic configuration of the pouch loading device]
[A] Characteristic configuration (1) By "the dimension from the center of the feed roll 8 to the entrance of the chute 16 is shorter than one pitch", even if the horizontal seal portion of the continuous packaging pouch has a habit of breaking. From the nip position of the feed roll 8 to the entrance of the chute 16, the posture is kept straight without being affected by the bending habit.
The vertical seal of the continuous packaging pouch 1 is fixed to the nip at the upper 27 (mm) position of the cut position, and the folded side is guided to almost the same position by the V-shaped groove of the folded side guide 7, so that the pouch pitch is increased. If it is 40 (mm) or more, even if the horizontal seal portion has a bending habit, this horizontal seal position is on the upstream side of the nip position of the feed roll 8, so the continuous packaging pouch on the downstream side (lower side) of the nip position. 1 can be held straight.
For this reason, the continuous packaging pouch 1 before cutting the leading pouch hangs straight down and is orthogonal to the moving direction of the cutter, so that the cutting force is transmitted straight to the pouch and miscut does not occur, and upstream from the cutter position immediately after cutting. Since the pouch 1a on the side is not tilted, clogging does not occur because the tip of the pouch interferes with the inlet part of the cutter or the chute inlet during the transfer when the transfer is started. By eliminating such miscuts and clogging, it is possible to improve the decrease in productivity due to the choco-stopping of the machine.

By "... the dimension to the entrance is shorter than one pitch" in the characteristic configuration (1), the tip of the pouch 1a enters the inside of the chute 16 by the time the bending habit passes through the nip position of the feed roll 8.
Further, since the dimension from the center position of the feed roll 8 to the chute inlet is 34 (mm), when the tip of the pouch having a pitch of 40 (mm) reaches the chute 16 inlet, the lateral seal portion 1b having a bending habit is fed. Since it is on the upstream side of the nip position of the roll 8, when it tries to enter the chute 16 opening straight without being affected by the bending habit and the lateral seal portion 1b having a bending habit reaches the nip position of the feed roll 8. It has entered the inside of the 6 (mm) chute 16. Therefore, clogging does not occur at the entrance of the chute 16.

[B] The characteristic configuration (2) "providing a transport guide" and the characteristic configuration (3) "the detection position of the pitch detector 11 coincide with the nip position of the feed roll 8". Therefore, at the pitch detection position, the folded side is fixed to the tip of the transport guide and the seal side is fixed to the nip, so that the continuous packaging pouch 1 is restricted from moving in the thickness direction and the width direction, and there is no transport flutter. Pitch can be detected in a stable posture, and variations in measurement accuracy are reduced.
By guiding the vertical seal and the folded side with a length several times the pouch pitch, there is no buckling (curving) in the length direction due to the influence of bending habits at the pitch position.

Further, since the transfer stop position by pitch detection and the nip fixing position of the feed roll 8 match from the characteristic configuration (3), the pitch does not shift when the transfer is stopped.

When intermittent transport is stopped, even if there is an overrun on the upstream side of the pitch detector 11, the transport guide 5 continuously guides both the vertical seal side and the folded side of the continuous packaging pouch 1 along the transport direction. As a result, the sliding resistance and the difficulty of buckling such that the lateral seal portion is uneven in the thickness direction make it difficult for excess feed to enter the transport guide 5.
Further, even if there is an overrun, since the vertical seal of the continuous packaging pouch is fixed to the nip at approximately the center position A of the diameter of the feed roll 8, the pouch is positioned in the transport direction at the detection position at the same position. There is no deviation, and the measurement data of the pouch length by boundary detection and the conveyed amount match.

[C] The characteristic configuration (4) "Adopting a cut-off method for the cutter unit 12 ..." uses a resistance that the horizontal seal portion tries to slip into the gap of the receiver, resulting in a V-shaped cutting edge. Can be easily pierced into the seal.

When the horizontal seal portion of the pouch is in front of the gap of the receiver 14, when one of the V-shaped cutting edges of the saw blade 13 collides, the cutting edge on the upper surface side of the saw blade is brought closer to the lower surface of the upper plate of the receiver. As a result, the resistance of the lateral seal portion to slip into the gap is increased, and the seal can be pierced without being excessively stretched. As the cutting edge advances, breakthroughs occur one after another, and when the full width breakthrough is completed, cutting is completed.

In addition, the saw blade and receiver are fixed so that they do not escape up, down, left, right, front and back, and even if there is bending due to bending habits, the force in the direction of travel of the saw blade does not escape up and down, and the cutting state is always constant. , The cutting force is also maintained in the maximum state.

[D] Characteristic configuration (5) By "shifting the supply speed according to the position of the dancer roll 3", the supply speed from the transfer roll 2 is increased when accelerating the intermittent transfer, and is decreased when decelerating. The dancer roll 3 can be kept almost horizontal. As a result, at the start of intermittent transportation of the feed roll 8, the transport speed> the supply speed, and the dancer lever 3a rapidly consumes the continuous packaging pouch from the intermediate pool portion and suddenly rises above the horizontal position. Although it moves, the dancer roll 3 jumps by increasing the transport speed (if the consumption is too large, the rise of the position wound around the dancer roll from below exceeds 1 G, and this acceleration causes the dancer roll to jump. To prevent it.

Further, when the intermittent transport of the feed roll 8 is stopped, the transport speed <the supply speed, and the dancer lever 3a is excessively supplied with the continuous packaging pouch to the intermediate pool portion and moves below the horizontal position, but the transport speed is lowered. This prevents the dancer roll 3 from separating from the continuous package pouch 1 (if the supply amount is too large, the folded position of the continuous package pouch is lower than the dancer roll position even if the dancer lever stops at the lower limit position).

[E] Characteristic configuration (6) By "increasing the apparent transport outer diameter of the top roll 4", the line connecting the outer circumferences of the plurality of rolls becomes a pseudo outer diameter of the large diameter roll. Further, when the round belt is wound around the combination roll of the top roll 4, it becomes a resistance to the free rotation of the roll. By combining a plurality of rolls, the transport line becomes a pseudo large diameter roll outer circumference and is wound. The continuous packaging pouch 1 is formed into a polygon with inconspicuous irregularities along the outer circumference thereof to reduce the difference between the opposite side length and the diagonal length.

Further, unlike the conventional large-diameter roll, the inertia of the roll is small, and it is easy to rotate when the pouch transport is started, and the rotation is stopped immediately when the pouch is stopped.

In addition, if the pouch weight is heavy, overrun may occur due to the inertia of the pouch weight when stopped. By wrapping the round belt around the roll, it becomes a resistance to the free rotation of the roll, and at the same time the intermittent transfer is stopped, the rotation of the roll is also stopped, and extra feeding is eliminated.

[F] Characteristic configuration (7) By "using an ultrasonic sensor capable of boundary detection for the miscut detector 17," miscut detection can be performed by sealing and the contents of a pouch that is not affected by bending habits. Detect the boundary of.
If the horizontal seal part at the tip of the leading pouch of the continuous package pouch 1 has a crease, the hanging length (stop position) from the cutter position may vary depending on the degree of bending of the seal part. The boundary position of is almost unaffected and the position is constant. In the embodiment, since the ultrasonic sensor of the miscut detector 17 detects the boundary between the seal portion and the content portion, the position can be correctly detected without being affected by the bending habit.

In addition, the dimensions of the miscut detection position and the cutter position are specified, and the horizontal seal portion is cut by determining the transfer distance from the time from the start of transfer to the stop of transfer by boundary detection and comparing it with the pitch measurement result. You can confirm that it was sent to the position properly.

[Effect of the characteristic configuration of the pouch loading device]
[A] Characteristic configuration (1) "The dimension from the center of the feed roll 8 to the entrance of the chute 16 is shorter than one pitch." ..

By making the distance from the feed roll 8 on the upstream side to the chute 16 inlet significantly closer (34 (mm) in the example) across the cut position, the pitch above this distance (40 (mm) to standard in the example). If the pouch is 40 (mm) or more in most cases, it can be transported without being clogged at the entrance of the cutter unit 12 or the entrance of the chute 16 even if it has a habit of breaking, and there is no miscut (body cutting).

The contents are scattered due to the broken body, and it is possible to eliminate the time to clean the dirty machine and the machine stop.

Further, since the clogged pouch is removed, it is possible to eliminate the dangerous work of removing the pouch from the cutter portion where there is a risk of injury to the operator.

[B] The characteristic configuration (2) "providing a transport guide" and the characteristic configuration (3) "the detection position of the pitch detector 11 coincide with the nip position of the feed roll 8". As a result, the pitch measurement accuracy is improved and miscutting is less likely to occur.

By improving the pitch measurement accuracy, the amount of feed to the cutter is also accurate, and the cut position deviation (miscut) is reduced.
Next, since the horizontal seal portion to be cut reaches the cut position only by sending 27 (mm) after detecting the boundary position, the decrease in the apparent length due to the bending due to the bending habit of the pouch is the allowable value of the cut position deviation. It becomes very small with respect to 2 (mm) or less, and miscut does not occur.

[C] Characteristic configuration (4) By "the cutter unit 12 employs a parting off cutting method composed of a saw blade 13 and a receiver 14," the seal is pierced even if there is bending due to a bending habit. Can be easily realized and does not miscut. Moreover, since it is not necessary to adjust the sliding of the blade surfaces of the lower blade and the upper blade, the blade replacement work can be completed in a short time even if the worker is not a skilled worker.

With the conventional guillotine type cutter blade, if the horizontal seal part has a bending habit, the lower blade pressed by the spring force against the blade surface of the upper blade escapes, creating a clearance and resulting in poor cutting. In the cutter unit 12 of the embodiment, since the saw blade 13 is fixedly attached without escape, the saw blade 13 does not escape and always hits the horizontal seal portion 1b under the same conditions even if the continuous packaging pouch 1 has a bending habit. It touches and breaks through, and miscuts due to bending habits do not occur.

The saw blade 13 and the receiver 14 are simply fixed to their respective mounting surfaces, and the cutting edge position of the saw blade 13 is the optimum parting condition with respect to the gap between the receiver 14.

Even if the horizontal seal slips into the gap of the receiver 14, the pouch always falls on the chute after cutting due to the action of the stripper 15.

[D] Characteristic configuration (5) By "shifting the supply speed according to the position of the dancer roll 3", the transport tension (determined by the weight of the dancer roll) is constant even if there is acceleration / deceleration of intermittent transport, and the transport flutter. By varying the supply speed of the carry-in roll 2, which eliminates sticking and improves pitch detection accuracy, the continuous packaging pouch 1 wound around the underhang does not separate from the dancer roll 3, and the continuous packaging pouch 1 is conveyed. The tension is a constant tension based on the weight of the dancer roll 3.

By making the tension from the top roll 4 to the feed roll 8 constant, fluctuations in tension due to intermittent transport are suppressed, and fluttering of transport is eliminated.

[E] Characteristic configuration (6) By "increasing the apparent transport outer diameter of the top roll 4", pitch measurement accuracy is improved by transporting without fluttering over, and slip and overrun due to roll inertia. Since there is no deviation in the amount of feed to the cutter due to, there is an effect of preventing miscuts (displacement of the cutting position of the horizontal seal portion, body cutting).
The continuous packaging pouch wrapped around the top roll 4 becomes a polygon with inconspicuous unevenness that smoothly follows the outer circumference, and by reducing the difference between the opposite side length and the diagonal length, the transport fluttering to the pitch detection position Can be prevented.

Further, since the top roll 4 has a small roll inertia, it can immediately follow the start / stop of the pouch transport and stop the rotation, so that the rotation stop of the roll does not affect the transport tension.

The round belt prevents free rotation due to the inertia of the pouch weight when decelerating and stopping, and does not generate extra feed.

[F] Characteristic configuration (7) By "using an ultrasonic sensor capable of boundary detection for the miscut detector 17," the lateral seal portion bends due to a bending habit, and the hanging length from the cutter position (stop position). ) Is different, the boundary between the seal and the contents can be detected, so the hanging length can be measured accurately, and a pouch that is miscut can be detected.
By detecting the boundary between the horizontal seal portion and the content portion instead of detecting the edge of the horizontal seal portion of the leading pouch, it is possible to detect miscut prevention without being affected by the bending habit of the leading pouch.

In the conventional technology, if there is a flutter at the pitch detection position, a pitch shift due to excessive feeding, or a habit of breaking the continuous packaging pouch, miscut (body breakage) occurs due to clogging at the cutter entrance or chute entrance, resulting in production. It was a major factor in the decline in sex.

However, in the pouch loading device of the present embodiment, the pitch detection position is made less than one pitch from the nip position of the long transport guide 5 and the feed roll 8 to the inlet of the chute 16, and the pitch detection position is made to match the nip position of the feed roll 8 and folded back. By guiding the side with the V-groove of the folded-back side guide 7, it was possible to eliminate miscuts without using a bending habit feeding device in the front stage of the pouch loading device.

In addition, an ultrasonic miscut detector 17 is used instead of the optical miscut detector to detect the boundary between the seal part and the content part, which are not easily affected by bending habits, to print a mark. It was possible to eliminate false detections due to bending habits without any problems.

9 to 14 are explanatory views of an operation in which the continuous packaging pouch 1 is conveyed, cut into a pouch, and loaded in the pouch loading device according to the embodiment.
In the pouch loading device of the embodiment, referring to FIGS. 9 to 14, clogging or miscutting (cutting of the body) occurs at the entrance of the cutter unit 12 or the entrance of the chute 16 without being affected by the bending habit of the continuous packaging pouch 1. Explain whether or not The horizontal seal portion having a crease is indicated by reference numeral 1b'.

(1) In the state where the feed of the continuous package pouch is started immediately after the cut, as shown in FIG. 9, immediately after the cut, the head of the continuous package pouch 1 is sandwiched between the feed rolls 8 at the position (a) in the figure, and , Positions (a) to (c) are guided by the folded-back side guide 7 (positions (b) to (c) are guided by the vertical seal side guide 6). In this state, it is assumed that the horizontal seal portion (1b') having a crease between the positions (a) and (b) is at the position of the symbol G. The pitch P between the horizontal seal portions is 40 (mm).

The vertical seal side of the continuous packaging pouch 1 is fixed to the nip by the feed roll 8, and the folded side is regulated in the V-shaped groove by the folded side guide 7, so that a straight posture is maintained.

When one transport of the continuous packaging pouch starts, the feed roll 8 is fixed to the nip and the folded-back side guide 7 is regulated to proceed straight up to 13 (mm).

(2) Next, the continuous packaging pouch 1 advances, and as shown in FIG. 10, the folding habit position (horizontal seal portion 1b') is conveyed to the nip fixing position. At this time, the transport advances by 13 (mm), and the tip of the pouch (position (a)) passes through the entrance of the chute 16 and reaches the position of 6 (mm) from the entrance, so that it interferes with the entrance of the chute 16. There is no such thing.

(3) When the folding habit position (horizontal seal portion 1b') of the continuous packaging pouch 1 approaches the outlet portion of the transport guide 7, as shown in FIG. 11, the continuous packaging pouch 1 is folded in the horizontal sealing portion 1b'. It can be tilted under the influence of habits (the pouch in (a) tilts).
(A) of the continuous packaging pouch 1 is inside the chute 16 from the state of FIG. 11, and proceeds along the slip surface of the chute 16 or the upper guide surface depending on the direction of the bending habit.

(4) When the lateral seal portion 1b'of the continuous packaging pouch 1 which has a bending habit reaches the cut position, it becomes as shown in FIG. When the saw blade 13 of the cutter unit 12 comes into contact with the seal, the upper and lower parts of the receiver 14 become fulcrums when the saw blade 13 of the cutter unit 12 comes into contact with the seal. , The convex part is corrected to be flat, and the cutting starts after the piercing resistance is generated.

(5) By cutting in FIG. 12, (a) of the continuous packaging pouch 1 is cut off and put into the chute 16, whereby the horizontal seal portion 1b'of (b) of the continuous packaging pouch 1 becomes the head.
When the lateral seal portion 1b'of the folding habit of the continuous packaging pouch 1 conveyed from that state reaches the detection position of the miscut detector 17, it becomes as shown in FIG. The horizontal seal portion 1b (1b') at the tip of the continuous packaging pouch 1 is bent due to the bending habit.

In FIG. 13, the dimensions from the cut position can vary depending on the edge and the bending angle of the horizontal seal portion 1b.
The position of the boundary between the horizontal seal portion 1b and the content storage portion (pocket 1a) does not change even if there is a habit of bending. Since the miscut detector 17 detects the boundary between the horizontal seal portion 1b and the pouch 1a, no detection error occurs.

(6) The operation of the stripper 15 after the cutting is completed will be described.
As shown in FIG. 14, in the cutter unit 12, cutting is completed with the horizontal seal portion 1b of the pouch cut between the receivers 14 of the cutter unit 12 slipping into the cutter unit 12.
Even if the lateral seal portion 1b is caught on the receiver, it is removed by the stripper 15 when the receiver 14 retracts.

FIG. 15 is a flowchart illustrating a control operation of the pouch loading device of the embodiment. Each step 101- of the process is abbreviated as S101-.

As described above, in the embodiment, the pitch of the continuous packaging pouch is 40 (mm), and the length of the horizontal seal portion 1b is 20 (mm) (10 (mm) in front and 10 (mm) in total, which is 20 (mm). ), 27 (mm) from the feed roll center position A to the cutter center position B, 7 (mm) from the cutter center position B to the entrance C of the chute 16, and the detection position D of the miscut detector 17 from the cutter center position B. Up to 30 (mm).

These sizes are examples and can be applied to continuous packaging sachets of various sizes. The position from the cutter center position B to the detection position D of the miscut detector 17 is the position of "pouch pitch length-seal length / 2".

First, it is determined whether or not the start button (start button) is pressed (S101), and if the start button is pressed (S101: Yes), the continuous packaging pouch 1 is conveyed (S102). The start button is on the operation panel 30 shown in FIG.

It is determined whether or not the pitch detector 11 has detected the boundary between the seal of the continuous packaging pouch and the content portion (S103).
After the boundary is detected (S103: Yes), it is determined whether or not the boundary of the continuous packaging pouch is conveyed by 27 (mm) (S104).

If it is transported (S104: Yes), the transport is temporarily stopped (S105), and the boundary between the horizontal seal portion at the top of the continuous packaging pouch and the content portion makes the miscut detector 17 slightly (± 2 (mm)). ) Is detected or not (S106). Specifically, the dimensions of the miscut detection position and the cutter position are specified, and the transport distance is calculated from the time from the start of transport to the stop of transport by boundary detection, and the pitch measurement result of the continuous packaging pouch (measured in advance). (Specified value) and judgment. In this case, if the detection position of the miscut detector 17 is within ± 2 (mm) from the tip position, it is judged to be suitable and “no miscut” (S106: Yes), while it is included. If not, it is inappropriate and it is determined that "miscut detection" (S106: No). In this way, it can be confirmed that the horizontal seal portion is properly sent to the cut position.

If the continuous packaging pouch is normally conveyed, the lateral seal portion 1b is located on the cutter unit 12, but the presence or absence of miscut is detected. That is, when the miscut detector 17 determines that the boundary between the horizontal seal portion at the beginning of the continuous packaging pouch and the content portion slightly passes, the pouch that has entered the inside of the chute 16 does not have its tip clogged in the middle. It can be determined that the transfer is completed normally and the central portion of the horizontal seal length is at the cut position.

If it is determined in S106 that there is no miscut (S106: Yes), the horizontal seal portion is cut by the cutter unit and the pouch is put into the chute. After that, it returns to S102 and resumes the transportation of the continuous package pouch.
On the other hand, if "miscut detection" is determined (S106: No), an alarm is notified and the process returns to S101.

The dimensions and structural operation of each part of the pouch loading device of the embodiment are examples and can be appropriately modified.

A modified example of the embodiment will be described below.
16 (a) to 16 (d) are schematic views for explaining the continuous packaging pouch loading process of the pouch loading device according to the modified example, and FIG. 17 is a detection and transporting process of the pouch loading device according to the modified example. It is explanatory drawing.

In the above-described embodiment, the pitch is detected above the cut position (pitch detector 11), and the miscut is detected below the cut position (miscut detector 17 (fixed position)). The upper pitch detector 11 was used for pitch feed, and the lower miscut detector 17 was used for the purpose of preventing miscuts.

In the modified example, only the detector corresponding to the upper pitch detector 11 in the above-described embodiment (the name is more suitable to be the cut position detector) conveys the center of the seal length to the cut position and miscuts. This is an embodiment for preventing the above. The lower miscut detector 17 was set at the position of "pouch pitch P-seal length S / 2" from the cut line CL (the position is changed for each pouch pitch) to serve as an auxiliary role. It is a thing.

In FIG. 16A, the horizontal seal portion (1b) between the pouch (1a) of 1 “a” and the pouch (1a) of 1 “b” is located at the cut line to cut the pouch of 1 “a”. Indicates the state to be used. The pitch length P indicates the seal length S and the cut line CL and is fed by the feed roll 8, and the pitch detector 11 functions as a cut position detector.

The pitch detector 11 to the cut line are located 27 (mm), and the miscut detector 17 from the cut line CL is installed at the position of PS / 2 just in case. In FIG. 16, the boundary between the horizontal seal portion and the pouch of 1 “b” is the front side A and the rear side B, and the boundary between the horizontal seal portion and the pouch of 1 “c” is the front side C and the rear side D.

After cutting the horizontal seal portion 1b in FIG. 16A, the lateral seal portion 1b is conveyed by S / 2 and the boundary B is detected by the pitch detector 11 as shown in FIG. 16B. Further, S is carried and the boundary C is detected as shown in (c).
Further, as shown in (d), the lateral seal portion is positioned at the cut line CL. When the lateral seal portion 1b at the tip is bent, the length is σ.

As shown in FIG. 17, with respect to the detection position of the pitch detector for the cut of each pouch, the transport to the cut position is 27 + BC dimension / 2.

A modification is a method in which the center of the seal length is conveyed to the cut position only by the upper pitch detector (the name is more suitable to be the cut position detector), and miscut is prevented. The lower miscut detector is set at the position of "pouch pitch P-seal length S / 2" from the cut line (the position is changed for each pouch pitch) and serves as an auxiliary role.

1) The precondition for the configuration of this modification is that the feed roll 8 from the nip position to the entrance of the chute is configured within one pitch of the pouch, and even if the pouch has a bending habit, the tip portion is the cutter entrance or The pouch posture is stable due to the configuration that does not cause clogging at the entrance of the chute and the configuration of the nip fixing on the vertical seal side and the V-shaped groove guide on the folded side at the pitch detection position (cut position detection position), and the seal and contents The condition is that the boundary position of the above can be detected stably (there is no variation in the measurement).

2) If the pouch is not clogged and the amount transported by the servo motor that drives the feed roll is "27 mm + BC dimension / 2", the center position of the horizontal seal length of the pouch to be cut is exactly the cut line position. We guarantee that they will match.

3) The fact that there is no variation in the detection of the boundary position means that the seal length S (dimension between BC) is actually measured by detecting the boundary B and the boundary C, and the amount of transport after detecting the boundary C is "27 mm + dimension between BC / 2". When the transfer is stopped, it is guaranteed that the cutting position is reached.

4) Since the configuration guarantees the assumption that the pouch is not transported and there is no detection variation in the boundary position, the center position of the seal length can always be cut without using the miscut detector under the cutter. , Miscut (non-uniform cutting of the upper and lower pouch seal length, cutting of the contents) does not occur.

5) The miscut detector 17 on the lower side of the cutter is an auxiliary to confirm just in case that the pouch to be cut was correctly transported without "clogging" (clogging) when being transported in the chute. Detector.

6) As for the setting position of the miscut detector, since the horizontal seal of the pouch may be bent due to a bending habit, the boundary position between the tip seal and the content part is detected instead of detecting the seal tip of the pouch.

7) Therefore, detecting the boundary position of the tip of the pouch to be cut indicates that the transfer is normally completed without being caught by "clogging" at the chute portion, and the lateral seal position of the cut position can be guaranteed. There is.
In the modified example, by clearing the precondition of 1), the miscut detector becomes unnecessary, so that there is an advantage that the configuration of the device can be simplified.

In the pouch loading device of the present invention, pouches containing powdered or liquid soup, kayak such as dried vegetables, confectionery or seasoning oil, or contents such as freshness preservatives and desiccants on instant noodles and foods are put into various packaging containers. It can be used for the device to be loaded.
