Description

  The present invention is effective when the leading end of a new packaging material is manually connected to the end when the supplied packaging material reaches the end of the strip-shaped packing material used for packaging the product as a package. The present invention relates to a paper splicing assisting device in a packaging machine that functions in a simple manner.

  Conventionally, the belt-shaped packaging material is fed out from a winding roll that has wound the belt-shaped packaging material, and the fed-out belt-shaped packaging material is passed through a cylinder-forming device (former) to be bent into a substantially cylindrical shape. Both sides of the belt-shaped packaging material to be fed are sealed with a center sealer to form a cylindrical packaging material, the product is supplied into the cylindrical packaging material through the filling cylinder, and the end of the cylindrical packaging material at the position between the products. 2. Description of the Related Art A bag making filling and packaging machine that manufactures a bag package by wrapping a product in a bag while manufacturing a bag by applying an end seal with a sealer is known. Bag making and packing machines include vertical bag making filling and packaging machines in which bag making machines are arranged vertically and products are thrown in from the top. There is a horizontal bag making and filling machine that is fed into the material.

  When the feeding of the belt-shaped packaging material from the winding roll approaches the end, normally, the operation of the bag-filling and packaging machine is interrupted, and a new winding roll is formed on the belt-shaped packaging material (referred to as “old belt-shaped packaging material”) to be finished. The belt-shaped packaging material (referred to as “new belt-shaped packaging material”) is connected (this operation is referred to as “paper splicing” operation), and the operation of the bag filling and packaging machine is resumed with the connected belt-shaped packaging material.

  Specifically, in the paper splicing operation, the old strip-shaped packaging material approaching the end is cut in the transverse direction, the cut end is placed on the paper splicer, and the cut end is placed on the paper splicer. This is done by placing the start ends (similarly, the cut end portions) of the new belt-shaped packaging material close to each other and connecting both the cut ends of the old and new belt-shaped packaging materials with a connecting tape such as an adhesive tape.

  In paper splicing work, the direction of both the old and new belt-like packaging materials and the edges on both sides are connected straight with no inclination or misalignment so that the subsequent operation of the bag making filling and packaging machine can be smoothly resumed. It is preferable to connect so as to be aligned with each other. To do so, when cutting the ends of the old and new strip-shaped packaging materials on the paper joint and connecting them with tape, fix the cut ends of both strip-shaped packaging materials that match the direction and position so that they do not move on the paper joint. There is a need to. This fixing method is generally used as a method in which a paper joint is constructed as an adsorption table, and the cut ends of both strips of packaging material are adsorbed and fixed to the paper joint, and the packaging material on the paper joint is further disposed thereon. And a method of fixing by pressing with a rubber magnet.

  As a method of adsorbing and fixing to a paper splicer, for example, there is a method described in Citation 1 or Citation 2. Cited Document 1 discloses a strip-shaped material adsorbing means capable of adsorbing a strip-shaped packaging material for performing termination processing such as paper splicing in connection with the end detection device for the strip-shaped packaging material. The strip-shaped material adsorbing means is arranged in a form along the travel path of the strip-shaped packaging material, and includes a suction plate having a width wider than the lateral width of the strip-shaped packaging material. The suction plate is formed with slits that extend in the transverse direction of the belt-shaped packaging material and through which the cutter can pass, and suction hole arrays that extend along the slits on both sides of the slit, and serve as a paper splicer. Each adsorption hole row adsorbs and holds the belt-shaped packaging material by, for example, a negative pressure generated with an ejector that blows out air.

  When it is determined that the end of the strip-shaped packaging material is close, the strip-shaped suction means operates immediately and sucks the strip-shaped packaging material. The strip-shaped packaging material is adsorbed in a state where the entire width is placed on the adsorption plate. By moving the cutter blade edge along the slit formed in the suction plate, the already supplied old belt-shaped packaging material is cut from the belt-shaped packaging material on the winding roll side. The starting edge of the new belt-shaped packaging material is placed in a state of being adsorbed by the suction plate along the cut end of the old belt-shaped packaging material, and paper splicing is performed by connecting the ends of both belt-shaped packaging materials with a paper joining tape.

  Cited Document 2 discloses a paper joining method and apparatus that enables pattern matching. That is, when the end of feeding of the packaging material from the take-up roll is detected, the control device performs a machine stop process and presses the packaging material with a rubber roll containing a one-way stopper that does not rotate in the conveyance direction of the packaging material. On the upstream side from the rubber roll containing the one-way stopper to the take-up roll, the machine is stopped in a state where an extra packaging material is left in the storage portion by the dancer roller. Remove the old paper tube from the take-up roll and set the new take-up roll in the take-up holder. The packaging material fixed by a rubber roll with a one-way stopper that can rotate only in the counter-conveying direction is pulled out in the direction of the new winding roll, and the papers are joined together by pattern matching between the surfaces. By simply pulling out the old packaging material in the direction of the roll, it is intended to carry out the paper splicing work without much effort.

  By the way, the belt-shaped packaging material fed out from the take-up roll is usually supplied to the packaging machine with the inner surface (printing pear) of the bag facing outside (upper side). The strip-shaped packaging material thus supplied is formed in a cylindrical shape so that the inner surface is inward in the cylinder making machine. In manual splicing work of old and new strip packaging materials, if you want to match the printing pattern on the surface of the strip packaging material, put a `` fold '' that crosses the width direction in either the old or new strip packaging material, It is a guide for pattern matching so that the pattern is connected at the position of the fold.

  In addition, in the paper splicing operation on the way from the take-up roll to the cylinder making machine of the packaging machine, since the printing surface of the strip-shaped packaging material being supplied is located on the back side, the worker usually performs printing. I can't see the pattern directly. In the case of a packaging material in which the light transmission such as an aluminum vapor deposition film is suppressed to substantially zero, the light is applied from the back side of the belt-shaped packaging material and the pattern is seen through (Patent Document 3). In the paper splicing operation position, two aluminum vapor deposition films are stacked, so even if the light is applied, the pattern is difficult to match or no pattern can be seen at all. If the paper is spliced with the position or angle misaligned, if the misalignment is a small misalignment of the packaging material feed pitch, it may be automatically absorbed in the paper feed control. If the amount is more than a certain amount, the deviation is not eliminated and a defective packaging is generated, and the product, the packaging film and the like are wasted.

  The strip-shaped packaging material that is fed from the take-up roll and sent to the packaging machine passes through the cylinder making machine and is provided with a vertical seal around the filling cylinder to form a cylindrical packaging material. Since it cannot be pulled back to the take-up roll side, the belt-shaped packaging material storage part can be placed by placing a dancer roller part or tension lever part in the middle of the packaging material supply path. The belt-shaped packaging material stored in the storage section is returned to the winding roll side. The amount of belt-wrapping material that can be rewinded from the dancer roller and tension lever is short, and the end of the old belt-shaped packaging material that is attached to the paper tube with tape or the like is peeled off from the paper tube to create a new belt-shaped material. It is difficult to pull out onto the packaging material.

  Therefore, in the paper splicing operation, the “wrapping material end notice” function or the like is used in advance, the machine is stopped before the belt-shaped packaging material is completely used, the belt-shaped packaging material is manually fed out, and the new winding roll Above, it becomes the operation | work which connects a strip | belt-shaped packaging material, adjusting the pattern of a printing surface. In general, the dancer roller portion and the tension lever portion may be configured by combining a plurality of rollers so as to be swingable at the end of each lever, and it may take time to manually rewind the belt-shaped packaging material. In addition, the accuracy of the “wrapping material end notice” function (remaining packaging material length accuracy) was also limited because it was influenced by the outer diameter of the paper tube.

Therefore, since the belt-shaped packaging material is always wound up with the printing surface facing outward in the winding roll, the old belt-shaped packaging material that has become the end of feeding is held back on the newly set new belt-shaped packaging material. If it can come, it can be connected while matching the pattern between the front side printed surfaces of the old and new belt-shaped packaging materials.
Regardless of the width dimension or material of the belt-shaped packaging material, there is a problem to be solved in that it is possible to easily perform the paper joining of the belt-shaped packaging material on the new winding roll.

  An object of the present invention is to solve the above-mentioned problem, and pulls back the old belt-shaped packaging material that is the end of the feeding, regardless of the width dimension and material of the belt-shaped packaging material, on the newly set new belt-shaped packaging material. It is to provide a paper splicing assisting device in a packaging machine that joins the old and new belt-shaped packaging materials while matching the patterns on the printing surfaces on the front side and facilitates paper splicing of the belt-shaped packaging materials.

  In order to solve the above-described problems, a paper splicing auxiliary device in a packaging machine according to the present invention includes a winding roll support portion that supports a winding roll that winds a belt-shaped packaging material, and is fed out from the winding roll. Further, in a packaging machine for manufacturing a package body in which a product that is a package is formed by forming the strip-shaped packaging material, the packaging machine frame close to the winding roll support portion is immediately after being fed out from the winding roll. The belt-shaped packaging material is stored immediately after feeding, and the packaging material storage amount in the storage portion just after feeding is stored in the storage zone just after feeding. The new strip-shaped packaging material in which at least the end of the strip-shaped packaging material separated from the winding roll is set on the winding roll support portion by releasing the storage of the winding roll Is an amount that allows the pullback on the winding roll, which consisted.

According to the paper splicing auxiliary device in this packaging machine, the end of the strip-shaped packaging material is separated from the winding roll in response to the end of the strip-shaped packaging material fed from the winding roll. Separation of the end of the belt-shaped packaging material is not limited to the case where the end of the belt-shaped packaging material attached to the winding paper tube of the winding roll is peeled off from the winding paper tube. Even when the strip-shaped packaging material is left in a wound state, the case where the strip-shaped packaging material fed from the winding roll is cut with a cutting tool such as a cutter to obtain the cut end is also included. In either case, the end of the strip-shaped packaging material is manually separated.
The paper splicing auxiliary device includes a storage unit immediately after feeding that stores the strip-shaped packaging material immediately after being fed out from the winding roll in the vicinity of the winding roll support unit. The packaging material can be released. The strip-shaped packaging material that is released from the storage portion immediately after feeding and is in a slack state can be pulled back upstream.

  The amount of packaging material stored in the storage section immediately after feeding is determined so that at least the end of the strip packaging material separated from the winding roll is released when the storage of the strip packaging material in the storage section immediately after feeding is released. The amount is sufficient to be pulled back onto the take-up roll of the new strip-shaped packaging material set in the above. Therefore, the end of the strip-shaped packaging material can be sufficiently pulled back onto the winding roll of the new strip-shaped packaging material by the packaging material storage amount in the storage section immediately after feeding. The end of the old strip-shaped packaging material that has been pulled back can be manually spliced to the new strip-shaped packaging material by using, for example, a thin adhesive tape on a winding roll of the new strip-shaped packaging material. At that time, since the printing surface of the strip-shaped packaging material is outside the winding roll, even if it is an opaque packaging material such as an aluminum vapor deposition film, paper joining is performed while visually checking the pattern alignment of the printing surface. be able to.

In the paper splicing assisting device in this packaging machine, the storage section immediately after feeding supports the first and second guide rolls around which the belt-shaped packaging material is wound, and both the guide rolls rotatably at both ends thereof. And a pair of swinging plates supported so as to be swingable with respect to the packaging machine frame, and a storage posture for storing the strip-shaped packaging material and the stored strip-shaped packaging material. It is possible to switch between a storage and release posture that is taken to release the storage, and in the storage posture that the storage portion takes immediately after the feeding, the winding of the band-shaped packaging material that is wound around the first and second guide rolls When the hanging path becomes longer, the belt-shaped packaging material is in a storage state, and is wound around the first and second guide rolls in the storage and release posture taken by the storage portion immediately after feeding. Said By winding path of the strip-shaped packaging material is reduced, the band wrapping material is stored released state, it can be that.
According to the paper splicing auxiliary device in this packaging machine, the posture taken by the storage section immediately after feeding is constituted by the first and second guide rolls and the rocking plate supported so as to be rockable with respect to the packaging machine frame. When the storage posture is set to the storage posture, the winding path of the belt-shaped packaging material wound around the two guide rolls becomes longer due to the positional relationship between the first and second guide rolls, so that the belt-shaped packaging material is in a storage state and immediately after feeding. When the posture that the storage unit takes is the storage and release posture, the positional relationship between the first and second guide rolls changes, and the winding path of the strip-shaped packaging material that is wound around both guide rolls is shortened. It becomes a storage release state.

In order to change the posture of the storage part immediately after the feeding, a turning operation lever pivotally attached to the packaging machine frame and pivotally attached to one of the swing plates, and the packaging machine A pair of guide portions that are provided on the frame and guide the movement of the common shaft provided on the two swing plates, and the storage portion immediately after the feeding is operated by operating the rotation operation lever. The posture can be switched between the storage posture and the storage release posture by rotating both the swinging plates and moving the common shaft while being guided by the two guide portions. Can do.
According to the paper splicing auxiliary device in the packaging machine, a configuration is obtained in which the rocking plate can be rocked with respect to the packaging machine frame by the rotation operation lever and the pair of guide portions. That is, when the rotation operation lever is operated by pivotally attaching the tip of the rotation operation lever to one of the oscillation plates and providing the oscillation plate with a common shaft movable along both guide portions. The movement of the two swing plates is a movement constrained by the turning operation lever whose tip moves in an arc shape and the guide paths of the two guide portions, and the two swing plates are the first guide roll and the second guide roll. Since it is in the linked state via the sway, it swings synchronously, and the posture of the storage part is changed immediately after feeding.

The both guide portions are parallel to each other along a groove fitting structure that fits into each longitudinal groove formed so that both end portions of the common shaft extend in the longitudinal direction in the packaging machine frame. A rack and pinion mechanism in which a pinion provided at an end of the common shaft is engaged with a guide rack provided may be configured.
According to the paper splicing auxiliary device in this packaging machine, the roll shaft of the first guide roll as the common shaft provided on the swing plate is fitted into the vertical groove formed in the packaging machine frame at the end thereof. In addition, the guide racks provided in parallel along the longitudinal grooves are engaged with pinions provided at both ends of the roll shaft of the first guide roll. By such a groove fitting structure and the rack and pinion mechanism, both the swing plates are reliably guided by the guide portion and moved. Since the common shaft is guided without deviating from the longitudinal groove, the pinion does not come out of engagement with the guide rack.
The common shaft may be a roll shaft of the first guide roll. By using the roll shaft of the first guide roll as the guide portion, the configuration can be simplified.

The first guide roll and the second guide roll have a feeding direction in which the belt-shaped packaging material is fed from the winding roll toward the packaging machine when the storage section immediately after feeding takes the storing posture. It can be arranged in a substantially perpendicular direction, and can be arranged substantially in the feeding direction when the storage section immediately after feeding takes the storing and releasing posture.
According to the paper splicing assisting device in this packaging machine, the arrangement in which the first guide roll and the second guide roll are aligned with respect to the feeding direction of the strip-shaped packaging material is changed according to the posture taken by the storage unit immediately after feeding. The length of the winding path of the belt-shaped packaging material wound around both guide rolls changes, and the posture taken by the storage portion immediately after feeding can be set to the storage posture or the storage release posture.

The take-up roll support unit may be loaded with one take-up roll or two take-up rolls arranged in an up-and-down state and rotatably supported in the loaded state.
According to the paper splicing auxiliary device in this packaging machine, the winding roll support portion is loaded with a single winding roll and rotatably supported in the loaded state when the packaging demand for the packaging machine is small. When the packaging demand is large, the two winding rolls are loaded in a floor-saving space in a state where they are arranged one above the other and are rotatably supported in the loaded state. The new winding roll already loaded can be immediately spliced.

The packaging machine includes a cylinder making machine configured to bend the belt-shaped packaging material into a substantially cylindrical packaging material, and a vertical seal portion that seals both side edge portions of the substantially cylindrical packaging material to form a cylindrical packaging material, A bag-filling-packaging machine comprising a lateral seal for producing a bag-packed body filled with a product while forming a bag by laterally sealing the cylindrical packaging material, and storing immediately after the feeding The film supply path that is downstream of the section and reaches the cylinder making machine includes a belt-shaped packaging material supply path storage section such as a dancer roller section and a tension lever section that can sufficiently store the strip-shaped packaging material. It can be said.
The paper splicing auxiliary device in this packaging machine is a roll making roll in a packaging material supply path from the take-up roll support part to the cylinder making machine in a bag making filling packaging machine comprising a cylinder making machine, a vertical seal part and a horizontal seal part. It can be applied to a position close to the support portion. Since the bag making filling and packaging machine is a packaging machine having a high packaging speed, the paper splicing assisting device can suitably cope with a case where the consumption of the belt-shaped packaging material is fast. When the bag-making filling and packaging machine is provided with a belt-shaped packaging material supply path storage section such as a dancer roller section or a tension lever section that can sufficiently store the belt-shaped packaging material in the packaging material supply path The paper splicing auxiliary device is disposed in the vicinity of the winding roll support portion in the path from the winding roll support portion to the belt-shaped packaging material supply path storage portion.

  As described above, the paper splicing auxiliary device in the packaging machine according to the present invention includes a storage unit immediately after feeding, which is disposed in the vicinity of the winding roll support unit and stores the belt-shaped packaging material immediately after being fed from the winding roll. The storage section immediately after feeding can release the stored strip-shaped packaging material, and the strip-shaped packaging material in a slackened state after being released from the storage section immediately after feeding can be pulled back to the upstream side. is there. The amount of packaging material stored in the storage section immediately after feeding is determined so that at least the end of the strip packaging material separated from the winding roll is released when the storage of the strip packaging material in the storage section immediately after feeding is released. Because the amount is enough to pull back onto the take-up roll of the new strip-shaped packaging material set in, the roll-up roll of the new strip-shaped packaging material is terminated by the amount of packaging material stored in the storage section immediately after feeding. It can be pulled back enough. When the strip wrapping material fed from the take-up roll reaches the end, the strip wrapping material manually separated from the paper tube is pulled back, and the end is brought onto the newly set strip wrapping material. On the winding roll of the strip-shaped packaging material, for example, by using a thin adhesive tape, a paper splicing can be manually made to the starting end of the new strip-shaped packaging material. At that time, since the printing surface of the strip-shaped packaging material is outside the winding roll, the end of the strip-shaped packaging material and the new winding are used regardless of the material of the strip-shaped packaging material such as an opaque packaging material such as an aluminum vapor deposition film. Paper rolls can be spliced while visually confirming the pattern alignment between the printing surfaces appearing on the front side of the new belt-shaped packaging material of the roll.

FIG. 2 is a view for explaining pulling back of the belt-shaped packaging material using the paper splicing auxiliary device shown in FIG. FIG. 3 is an explanatory view showing the relationship between the paper splicing auxiliary device and the packaging material feed path in the packaging machine shown in FIG. FIG. 4 is a perspective view showing an example of a packaging machine to which the paper splicing auxiliary device in the packaging machine according to the present invention is applied.

  Hereinafter, an embodiment of a paper splicing auxiliary device in a packaging machine according to the present invention will be described with reference to the accompanying drawings. FIG. 4 is a perspective view showing an example of a packaging machine to which the paper splicing auxiliary device in the packaging machine according to the present invention can be applied. The wrapping machine shown in FIG. 4 feeds a strip-shaped packaging material from a winding roll supported by a winding roll support, and forms the rolled-out packaging material into a cylindrical packaging material around a vertically placed filling cylinder. Then, the product is packed into the obtained cylindrical packaging material through the product that is the package, and the cylindrical packaging material filled with the product is sealed to produce a bag package in which the product is packaged. It is a bag filling and packaging machine.

  In the vertical bag making filling and packaging machine 50 shown in FIG. 4, the belt-like packaging material Fw fed from the take-up roll Fr is guided to a former 51 which is a cylinder making machine and charged with a product to be packaged. It is bent so as to wrap the cylinder 52, and both side edge portions fe and fe are overlapped, for example, in a palm shape on the front side of the former 51, and the overlapped side edge portions fe and fe are provided with a pair of vertical seal bars 53a and 53a. A vertical seal is applied by the sealing device 53 to form the cylindrical packaging material Ft. The cylindrical packaging material Ft is drawn down while being sucked by the packaging material feeding devices 54 and 54 that are provided on both the left and right sides of the filling cylinder 52 and operate synchronously, and is fed to the lower side of the filling cylinder 52. By the seal / cutter device 60, the cylindrical packaging material Ft is laterally sealed, and the bag B filled with the product at the tip of the cylindrical packaging material Ft is cut from the cylindrical packaging material Ft at the site of the horizontal seal. The bag package body Bp which is separated and is a finished product is manufactured.

  Each packaging material feeder 54 is wound around a driving timing pulley 55, a driven timing pulley 56, a guide timing pulley 57, and these timing pulleys 55 to 57, and a series of suction holes 59 are opened on the surface. The timing belt 58 is provided. A negative pressure box (not shown) is disposed inside the timing belt 58 in a region in contact with the cylindrical packaging material Ft. The cylindrical packaging material Ft is pulled down below the filling cylinder 52 by the timing belts 58, 58 while being sucked through the suction holes 59 of the timing belts 58, 58, and accordingly, the belt-shaped packaging material Fw is taken up by the winding roll Fr. It is paid out from.

  Although not shown in detail, the horizontal seal / cutter device 60 disposed below the filling cylinder 52 includes two horizontal seal heater members 61 and 61 which are arranged opposite to each other. The horizontal sealing heater members 61 and 61 are provided with a heat sealing member that seals two horizontal strips, and a cutter mechanism 62 that cuts the cylindrical packaging material Ft laterally at an intermediate position between the horizontal strips (the cutter blade and the cutter blade enter it). Groove). The horizontal seal heater members 61 and 61 of the horizontal seal / cutter device 60 may not move in the vertical direction and may only perform opening / closing operations. Combined, circulates and moves in a closed loop orbit such as a box shape or D-shape, and moves together in a straight line in synchronization with the flow of the cylindrical packaging material Ft without stopping the feeding of the packaging material Then, a box motion that can increase the sealing time may be performed.

  The winding roll Fr is supported by a winding roll support provided on the packaging machine frame behind the bag making filling and packaging machine 50. The take-up roll support part is provided with a loading shaft 70 for fitting and mounting the paper tube of the take-up roll Fr. Since the unused winding roll Fr is obtained by closely winding a very long strip-shaped packaging material Fw around the paper tube Rc, it has a considerable weight. Considering the workability of transporting the take-up roll Fr and loading to the loading shaft 70, the loading position of the take-up roll Fr is usually at the back side of the vertical bag making filling packaging machine 50 and at a low position near the installation floor. It is said that.

  During operation of the bag making and filling machine 50, the loading shaft 70 is rotationally driven by a feeding servo motor (not shown), and the belt-like packaging material Fw is fed from the take-up roll Fr according to consumption in the packaging machine. The feeding timing, the feeding speed and the feeding amount are controlled. The strip-shaped packaging material Fw fed from the winding roll Fr is supplied to the former 51 through the packaging material joint portion 71, the tension lever portion 72, the adjustment roll portion 73, and the like. A plurality of guide rolls 75 are arranged at appropriate positions in the packaging material supply path to guide the belt-shaped packaging material Fw together with the printing device 74 and various sensors for controlling the packaging material supply. In the tension lever portion 72, the belt-shaped packaging material Fw having some length can be stored, and the slack of the belt-shaped packaging material Fw is absorbed, and the feeding of the belt-shaped packaging material Fw from the winding roll Fr is stopped. Also allows several bags to be manufactured continuously.

  The paper splicing auxiliary device 1 according to the present invention is disposed in association with the winding roll Fr. In the case of the vertical bag making and packaging machine 50 shown in FIG. 4, the belt-like packaging material Fw fed from the take-up roll Fr can be replaced with the packaging material joint portion 71 before reaching the tension lever portion 72.

  FIG. 1 is a perspective view showing an embodiment of a paper splicing auxiliary device 1 according to the present invention. As shown in FIG. 1, packaging machine frames 2, 2 are arranged on the rear side of a packaging machine such as a vertical bag making filling packaging machine 50 so as to face left and right. Although the outlines of the packaging machine frames 2 and 2 are drawn for the sake of explanation, a part of the packaging machine frames 2 and 2 arranged on the back side is also illustrated as being partially transparent. Moreover, although the packaging machine frames 2 and 2 are a pair of opposing arrangement in the illustrated one, they may be one connected frame. The take-up roll support portion is arranged close to the packaging machine frames 2 and 2 but is not shown because it is separated from the packaging machine frames 2 and 2. Between the left and right wrapping machine frames 2, 2, there is a storage unit 3 immediately after feeding that can store the belt-shaped packaging material Fw immediately after being fed out from the winding roll Fr and can release the stored belt-shaped packaging material Fw. Is provided.

  The storage unit 3 immediately after feeding is supported so that the first guide roll 4 and the second guide roll 5 which are parallel to each other around which the belt-shaped packaging material Fw is wound, and both the guide rolls 4 and 5 are rotatable at both ends thereof. A pair of oscillating plates 6 and 6 are provided so as to be able to oscillate with respect to the packaging machine frames 2 and 2. The rotation axis of the first guide roll 4 and the second guide roll 5 is horizontally arranged, and the pair of swing plates 6 and 6 are vertically arranged and opposed to each other and symmetrically arranged.

  In order to change the posture of the storage unit 3 immediately after feeding by swinging the swinging plates 6 and 6, the packaging machine frames 2 and 2 are provided with rotating operation levers 8 and 8 and guide units 10 and 10 (described later).

That is, a rotation shaft 11 for the rotation operation levers 8 and 8 is spanned between the packaging machine frames 2 and 2, and the rotation shaft 11 is rotated to the packaging machine frames 2 and 2 at both ends thereof. It is pivotally supported. Rotating operation levers 8 and 8 are fixedly attached to the rotating shaft 11 in the vicinity of the opposed inner sides of the packaging machine frames 2 and 2. The tips 8a and 8a of the pivot operation levers 8 and 8 are pivotally attached to the swing plates 6 and 6 by pivot shafts 12 and 12 (only the front swing plate 6 is shown).

  In order to rotate the rotation operation levers 8, an operation air operating mechanism 14 is swingably attached to one packaging machine frame 2. The output rod 15 of the air operating mechanism 14 is pivotally attached to the tip 16 a of the intermediate lever 16 attached to the rotating shaft 11. Therefore, when the output rod 15 of the air operating mechanism 14 advances / retreats from the cylinder by the air pressure (the operation of (A)), the intermediate lever 16 rotates with the rotating shaft 11 around the rotating shaft 11 ((RO ) Behavior). The rotation of the rotation shaft 11 causes the rotation operation levers 8 and 8 to rotate on either packaging machine frame 2 side (operation (C)), and both the swing plates 6 and 6 swing. Each rocking plate 6 has the rotation shafts of the first guide roll 4 and the second guide roll 5 and the pivot shaft 12 of the tip 8a of the rotation operation lever 8 distributed around the apexes of the triangle as shown in the figure. It is formed in the triangle board arranged in this way. The storage system 3 immediately after feeding and the operating system from the air operating mechanism 14 to the rotating operation levers 8 and 8 are provided inside the packaging machine frames 2 and 2.

  The guide portion 10 that regulates the swing of the swing plate 6 together with the pivot shaft 12 of each rotation operation lever 8 is a groove fitting structure 20 and a rack and pinion mechanism 22 provided in each packaging machine frame 2. is there. The roll axis of the first guide roll 4 is a common axis for both swing plates 6 and 6. In each packaging machine frame 2, the groove fitting structure 20 is configured by fitting into a longitudinal groove 21 formed so that the end of the roll shaft of the first guide roll 4 extends in the longitudinal direction in the packaging machine frame 2.

The rack and pinion mechanism 22 is configured by a pinion 25 meshing with a rack tooth 24 of a guide rack 23. Since the roll shaft of the first guide roll 4 enters the longitudinal groove 21, the rack and pinion mechanism 22 is not disengaged. In addition, the two rocking plates 6 and 6 are synchronized in operation by meshing in the rack and pinion mechanisms 22 and 22 on both sides.

  The rocking plates 6 and 6 are linked to each other via the first guide roll 4 and the second guide roll 5 and are integrated. Since the swing plate 6 is directly driven with the tip 8a of the swing operation lever 8 moving in an arc shape, the locus of the pivot shaft 12 of the swing operation lever 8 on the swing plate 6 is rotated. The trajectory of the tip 8a of the operation lever 8 is the same, and the movement path of the roll shaft of the first guide roll 4 is restricted by the vertical groove 21 of the guide portion 10 and the rack and pinion mechanism 22 of the first guide roll 4. Therefore, when the air operating mechanism 14 is operated and the turning operation lever 8 is turned, the swinging motions of both the swinging plates 6 and 6 are uniquely determined and are swung synchronously. Accordingly, the storage unit 3 immediately after feeding is balanced from the left and right sides between the storage posture for storing the strip-shaped packaging material Fw and the storage-release posture for releasing the stored strip-shaped packaging material Fw, as will be described later. Changed.

  FIG. 2 shows a state (a) in which the strip-shaped packaging material Fw of the winding roll Fr is used up and a state (b) of paper splicing to the strip-shaped packaging material of the new winding roll. The winding rolls are installed in two upper and lower stages, and FIG. 2 (a) shows the strip-shaped packaging when the strip-shaped packaging material Fw is used up for the upper winding roll Fr1 and the lower winding roll Fr2. The feeding path of the material Fw is shown. Further, FIG. 2 (b) shows a mode when paper splicing is performed on the upper winding roll Fr1 or the lower winding roll Fr2. The take-up roll support unit may be loaded with the take-up roll Fr as one stage instead of two stages up and down in response to a request for packaging speed or the like. When loading two take-up rolls, as shown in the figure, load them into a floor-saving space by arranging them in two upper and lower stages, and when replacing the take-up roll, Can be spliced immediately to a roll.

  As shown in FIG. 2 (a), when the packaging machine is operated to feed the belt-shaped packaging material Fw from the take-up roll Fr, the rotation operation lever 8 occupies a substantially upright position, and the swinging plate 6 The first guide roll 4 occupies the highest position in the groove 21 of the guide portion 10, and the second guide roll 5 of the swinging plate 6 occupies a position lower than the pivot shaft 12 of the rotation operation lever 8. And the storage part 3 immediately after delivery is in the storage posture P1 which stores the strip | belt-shaped packaging material Fw.

  When the storage unit 3 immediately after feeding takes the storage posture P1, the first guide roll 4 and the second guide roll 5 are in the feeding direction XX in which the strip-shaped packaging material Fw is fed from the winding roll Fr toward the packaging machine. Are arranged in a substantially orthogonal direction (vertical direction YY). In the storage posture P <b> 1 taken by the storage unit 3 immediately after feeding, due to such a positional relationship between the first guide roll 4 and the second guide roll 5, the winding path of the belt-shaped packaging material Fw wound around the both guide rolls 4, 5 becomes long. Thereby, the strip-shaped packaging material Fw will be in a storage state.

  As shown in FIG. 2B, when the operation of the packaging machine is stopped and the end of the used strip-shaped packaging material Fw is spliced to the strip-shaped packaging material Fw of the new winding roll Fr, the rotation operation lever 8, the first guide roll 4 of the swing plate 6 occupies the position where the groove 21 of the guide part 10 is lowered most, and the second guide roll 5 of the swing plate 6 is the first guide. It occupies substantially the same height as the roll 4, and the storage part 3 immediately after feeding is in a storage and release posture P2 for releasing the stored strip-shaped packaging material Fw.

  When the storage part 3 immediately after feeding takes the storage and release posture P2, the first guide roll 4 and the second guide roll 5 are moved in the feeding direction XX in which the belt-shaped packaging material Fw is fed from the winding roll Fr toward the packaging machine. On the other hand, it is arranged in a direction substantially along. In the storage and release posture P2, the winding path of the strip-shaped packaging material Fw wound around the two guide rolls 4 and 5 is shortened by such a positional relationship between the first guide roll 4 and the second guide roll 5, and thus the strip-shaped packaging material. Fw enters the storage and release state. The old strip-shaped packaging material Fw that has been released from the storage unit 3 immediately after feeding and is in a slack state can be pulled back to the upstream side, that is, the outer surface that is the printing surface of the new winding roll Fr.

  Thus, according to the paper splicing auxiliary device 1, the arrangement relationship of the first guide roll 4 and the second guide roll 5 with respect to the feeding direction of the strip-shaped packaging material Fw changes according to the posture taken by the storage unit 3 immediately after feeding. Therefore, the length of the winding path of the strip-shaped packaging material Fw wound around both guide rolls 4 and 5 changes, and the storage posture P1 taken to store the strip-shaped packaging material Fw in the posture taken by the storage unit 3 immediately after feeding, It is possible to switch between the storage release posture P2 taken to release the storage of the stored strip-shaped packaging material Fw.

  The amount of packaging material stored in the storage unit 3 immediately after feeding is at least that of the old belt-shaped packaging material Fro separated from the old winding roll Fr by releasing the storage of the band-shaped packaging material Fw in the storage unit 3 immediately after feeding. The amount is sufficient to enable the end Ef to be pulled back onto the winding roll Fr of the new strip-shaped packaging material Fwn set on the winding roll support. Therefore, the terminal Ef of the old belt-shaped packaging material Fwo can be sufficiently pulled back onto the new winding roll Frn with the packaging material storage amount in the storage unit 3 immediately after feeding.

  The procedure for splicing is as follows. The end Ef of the old strip-shaped packaging material Fwo is separated from the old winding roll Fro in response to the end of the strip-shaped packaging material Fw fed from the winding roll Fr. The separation of the end Ef of the old strip-shaped packaging material Fwo includes not only the case where the pasting end Ef of the old strip-shaped packaging material Fwo attached to the winding paper tube of the winding roll Fro is peeled off from the winding paper tube, Even if some old belt-shaped packaging material Fwo is left in a wound state on the winding paper tube, the old belt-shaped packaging material Fwo fed out from the old winding roll Fro is cut with a cutting tool such as a cutter. The cutting end Ef is also included. In any case, the end of the old belt-shaped packaging material Fwo is manually separated.

  The end Ef of the old strip-shaped packaging material Fwo pulled back onto the new winding roll Frn is manually spliced to the new strip-shaped packaging material Fwn on the new winding roll Frn using, for example, a thin adhesive tape Ta. Is done. At that time, since the printing surfaces of the old and new strip-shaped packaging materials Fwo and Frn are both on the same outside, even if the strip-shaped packaging material Fw is an opaque packaging material such as an aluminum vapor deposited film, the pattern alignment of the printed surface is visually observed. You can splice while checking.

  As described above, the packaging machine to which the paper splicing auxiliary device 1 is applied is a vertical type product that includes a former 51 as a cylinder making machine, a vertical seal portion 53, and a horizontal seal portion 60 that can be operated at high speed. Although it may be the bag filling and packaging machine 50, the belt-like packaging material Fw such as the tension lever part (dancer roller part) 72 is sufficiently stored in the packaging material supply path to the former 51 that is downstream of the storage part 3 immediately after feeding. It may be provided with a belt-shaped packaging material supply path storage section that can be used. In such a case, the paper splicing auxiliary device 1 can be applied between the winding roll support portion and the tension lever portion 72.

  FIG. 3 shows a strip-shaped packaging material supply path storage section that can sufficiently store the strip-shaped packaging material Fw such as the tension lever section (dancer roller section) 72 in the packaging material supply path on the downstream side of the storage section 3 immediately after feeding. An example provided is shown. The storage unit 3 immediately after feeding can pull the old belt-shaped packaging material Fwo back to the new winding roll Frn without pulling the belt-shaped packaging material Fw that has been fed downstream to the upstream side, but more If it is desired to obtain the amount of pulling back, the old strip-shaped packaging material Fwo that has been fed to the downstream side of the storage part 3 immediately after feeding, for example, the tension lever part 72, is tension-returned by the tension lever part 72. Thus, it is possible to pull back to the new winding roll Frn side.

  FIG. 3B shows a state in which the swing angle θ2 of the tension lever portion 72 cannot be sufficiently obtained by the peripheral equipment 81 such as a pump or a pipe when trying to obtain a larger pullback amount. In such a case, as shown in FIG. 3 (a), the rotation center 80 of the tension lever portion 72 is adjusted so that the tension arm or roller of the tension lever portion 72 does not interfere with the surrounding equipment 81. A large swing angle θ1 can be secured by lowering to a middle height in the vertical range. Since the amount of packaging material stored in the belt-shaped packaging material supply path storage unit increases corresponding to the large swing angle θ1, the amount of packaging material pulled back to the winding roll can be increased by loosening this.

  A bag making filling and packaging machine including a cylinder making machine, a vertical seal part, and a horizontal seal part usually allows an operator to access the back side of the packaging machine for replacement of the take-up roll Fr or paper splicing of the packaging material. Is installed. When the winding roll Fr is replaced, an operation of connecting the start end of the new wound winding roll Fr to the end of the old belt-shaped packaging material that has been used is performed. In order to efficiently perform such a paper splicing operation, the paper splicing device 1 is positioned at a position where it is easy to perform the paper splicing operation in the vicinity of the take-up roll support portion in the packaging material supply path from the take-up roll support portion to the cylinder making machine. Be placed. Although the paper splicing auxiliary device 1 has been described as being applied to a vertical bag making filling and packaging machine, it is obvious that it may be applied to a horizontal bag making filling and packaging machine.
