In the horizontal pillow packaging machine 1A that continuously manufactures the bag packaging body Bp, the strip-shaped packaging material Fw wound around the packaging material roll Fr is consumed as the packaging operation progresses, and approaches the end thereof. From the request to enable continuous operation of the horizontal pillow wrapping machine 1A, it is necessary to join the strip-shaped wrapping material of the new wrapping material roll and the paper joint. Paper splicing is usually performed by joining old and new strip-shaped packaging materials with tape on a paper splicing plate 9b. In the case of the horizontal pillow packaging machine 1A shown in FIG. 1B, the end of the strip-shaped packaging material Fw is completely fed by the packaging material feed roller portion 4, that is, the end of the strip-shaped packaging material Fw is the packaging material feed roller portion 4 It is preferable to perform the paper splicing when the paper is still left on the upstream side of the paper. Therefore, the paper joint plate 9b is arranged on the upstream side of the packaging material feed roller portion 4, that is, between the cushion roller portion 5A and the packaging material feed roller portion 4 in the packaging material supply device 2A, and the old paper joint plate 9b is placed on the paper joint plate 9b. Paper splicing is performed by connecting the vicinity of the end of the strip-shaped wrapping material and the start end of the new strip-shaped wrapping material with tape. Since the traveling path of the strip-shaped packaging material Fw from the cushion roller portion 5A to the packaging material feed roller portion 4 is horizontal, the paper joint plate 9b is below the traveling path of the strip-shaped packaging material Fw and the strip-shaped packaging material Fw. It is arranged horizontally along the.

The specific paper splicing work is performed as follows. That is, when the feeding of the strip-shaped packaging material from the packaging material roll Fr is completed, the strip-shaped packaging material Fw is sandwiched between the packaging material feeding rollers 4a and 4b of the packaging material feeding roller portion 4 and is sandwiched between the ends or the vicinity thereof. The packaging material is placed on the paper splicing plate 9b. The packaging material roll that has been unwound is removed from the roll support shaft 3a of the packaging material roll support portion 3, a new packaging material roll is loaded on the roll support shaft 3a, and the cushion roller portion 5A is pulled out from the new packaging material roll. The starting end of the new strip-shaped wrapping material that has been passed is overlaid on the old strip-shaped wrapping material on the paper joint plate 9b. On the paper joint plate 9b, the vicinity of the end of the old strip-shaped wrapping material and the start end of the new strip-shaped wrapping material are connected by tape or the like.

In order to assemble the paper joint plate 9b in the packaging material supply device 2A, a predetermined distance is provided from the cushion roller portion 5A and the packaging material feed roller portion 4 so as not to interfere with the cushion roller portion 5A and the packaging material feed roller portion 4. Need to be placed. Therefore, between the cushion roller portion 5A and the packaging material feed roller portion 4, in addition to the lateral dimension length of the paper joint plate 9b, the cushion roller portion 5A and the packaging material feed roller portion 4 are placed before and after the paper joint plate 9b. It is necessary to have a marginal length to reach each of them, and it is necessary to secure a considerable space in advance as a whole. As a result, the length of the packaging material supply device 2A becomes considerably long, the packaging material supply device 2A becomes large, and the paper joint plate 9b needs to be individually attached to the packaging material supply device 2A. This is one of the causes of the increase in the manufacturing cost of the horizontal pillow wrapping machine 1A.

Patent Document 2 discloses an example in which a cushion roller for applying tension to a strip-shaped packaging material is provided in a packaging material supply device of a horizontal bag-making filling and packaging machine. The band-shaped packaging material unwound from the packaging material roll is wound around the cushion roller, and the urging force of the coil spring acts on the band-shaped packaging material via the cushion roller, and if the band-shaped packaging material has slack, the urging force is concerned. The slack is absorbed based on the above, and after the slack is absorbed, the band-shaped packaging material is given a tension by the urging force. Since the spring force of the coil spring is adjustable, the urging force acting on the strip-shaped packaging material can be adjusted. For example, when the packaging machine is stopped due to the suspension of product supply, when the band-shaped packaging material that the packaging material roll is unwound due to its rotational inertia causes slack, the slack is absorbed by the urging force of the cushion roller of the tension mechanism. The strip-shaped packaging material is tensioned. In addition, since the brake mechanism operates based on the urging force of the tension mechanism to brake the rotation of the packaging material roll, the extra feeding of the band-shaped packaging material from the packaging material roll is stopped, and the tension action state of the band-shaped packaging material is checked. It is designed to be maintained.

FIG. 4 is a perspective view showing an example of a conventional horizontal pillow wrapping machine.

An example of a packaging material supply device for a packaging machine according to the present invention and a horizontal pillow packaging machine provided with the packaging material supply device will be described below with reference to the drawings. FIG. 1A shows an embodiment of a packaging material supply device for a packaging machine according to the present invention and a horizontal pillow packaging machine provided with a packaging material supply device, wherein substantially tubular and tubular packaging materials are used. It is a schematic diagram which showed to run laterally from the left to the right. The packaging machine main body 10 of the horizontal pillow packaging machine 1 other than the packaging material supply device 2 is the same as the packaging machine main body 10 of the conventional horizontal pillow packaging machine 1A shown in FIGS. 1 (b) and 4. By using the same reference numerals for the same device and the like, detailed description will be omitted again.

In the horizontal pillow packaging machine 1 shown in FIG. 1A, the strip-shaped packaging material Fw is unwound from the packaging material roll Fr supported by the packaging material roll support portion 3 as in the case of the conventional horizontal pillow packaging machine 1A. The unwound strip-shaped packaging material Fw is guided by the rotatable guide rolls 6a, 6b, 6c for which the route through which the strip-shaped packaging material Fw travels is determined. The strip-shaped packaging material Fw sent to the cylinder making device (former) 11 by the packaging material supply device 2 is formed into a substantially tubular shape in the cylinder making device 11, and then center-sealed by the center sealing device 13 on the overlapped edges. Is applied and molded into a tubular packaging material Ft. The product A to be packaged is sent into the tubular packaging material Ft by the product supply conveyor 8 of the product supply device 7. The packaging material is fed while being pulled by the packaging material pulling roller device 12.

A bag package Bp containing the product A is manufactured.

The packaging material supply device 2 of the horizontal pillow packaging machine 1 is also the same as the packaging material supply device 2A of the conventional horizontal pillow packaging machine 1A except for the cushion roller portion 5. That is, the packaging material supply device 2 has a packaging material roll support portion 3 that supports the packaging material roll Fr around which the strip-shaped packaging material Fw is wound, and a lateral direction (right direction in the drawing) with respect to the packaging material roll support portion 3. ), The strip-shaped packaging material Fw is provided with a packaging material feeding roller portion 4 for feeding the strip-shaped packaging material Fw to the packaging machine main body 10 of the horizontal pillow packaging machine 1. In the packaging material supply device 2, the strip-shaped packaging material Fw unwound from the packaging material roll Fr is sent out to the packaging machine main body 10 of the horizontal pillow packaging machine 1 by the packaging material feeding roller unit 4. A cushion roller portion 5 for applying tension to the strip-shaped packaging material Fw is arranged between the packaging material roll support portion 3 and the packaging material feed roller portion 4. Tension is applied to the strip-shaped packaging material Fw between the packaging material roll support portion 3 and the packaging material feed roller portion 4 by the action of the cushion roller portion 5, and the strip-shaped packaging material Fw between the two portions 3 and 4 loosens. Is prevented from occurring.

As the packaging operation of the horizontal pillow packaging machine 1 progresses, the consumption of the strip-shaped packaging material Fw unwound from the packaging material roll Fr supported by the packaging material roll support portion 3 advances to near the end thereof. In this case, the strip-shaped packaging material Fw unwound from the packaging material roll Fr newly loaded in the packaging material roll support portion 3 is connected to the strip-shaped packaging material Fw whose end is formed by being unwound from the packaging material roll Fr. Then, the old and new strip-shaped packaging materials are spliced together.

The paper joint plate 20 is not retrofitted after the packaging material roll support portion 3 and the packaging material feed roller portion 4 are assembled, but is pre-unitized in the cushion roller portion 5. The paper joint plate 20 occupies a position immediately downstream of the cushion roller portion 5 when viewed in the feeding direction of the strip-shaped packaging material Fw from the cushion roller portion 5 toward the packaging material feed roller portion 4 with respect to the cushion roller portion 5. It is unitized by arrangement.

Due to the unitization of the paper joint plate 20 in the cushion roller portion 5 in this arrangement, the paper joint plate 20 is arranged at a position as close as possible to the cushion roller portion 5. Since the paper joint plate 20 is unitized so as to occupy the position immediately downstream of the cushion roller portion 5, the vicinity of the end of the strip-shaped packaging material Fw is a new strip-shaped wrapping at the position immediately downstream of the cushion roller portion 5. The material Fw and the paper joint are made. The length of the old strip-shaped packaging material Fw remaining on the cushion roller portion 5 side from the paper joint position is shortened, and the old strip-shaped packaging material Fw can be effectively consumed for packaging.

With this unitization, the cushion roller portion 5 and the packaging material feed roller portion 4 can be arranged as close as possible to each other. As shown in FIG. 1 (a), the length L1 between the packaging material feed roller portion 4 and the cushion roller portion 5 is increased by unitizing the paper joint plate 20 into the cushion roller portion 5 (b). Compared with the length L2 between the packaging material feed roller portion 4 and the cushion roller portion 5A in the conventional packaging material supply device 2A shown in the above, a considerable reduction can be obtained. Therefore, in the horizontal pillow packaging machine 1, the structure of the packaging material supply device 2 is miniaturized and simplified, and the assembling work of the cushion roller portion 5 is simplified. The length of the old strip-shaped packaging material Fw remaining on the upstream side of the packaging material feed roller portion 4 becomes as short as possible, and the old strip-shaped packaging material Fw can be consumed for packaging as efficiently as possible in the horizontal pillow packaging machine 1. it can.

FIG. 2 is an enlarged perspective view showing an embodiment of a packaging material supply device for a packaging machine provided in the horizontal pillow packaging machine shown in FIG. The cushion roller portion 5 guides the cushion roller 21 around which the strip-shaped packaging material is wound, the support 22 that rotatably supports the cushion roller 21, and the support 22 in a direction orthogonal to the rotation axis Lc of the cushion roller 21. The guide body 23 and the urging means 24 that apply an urging force to the support 22 and apply tension to the strip-shaped packaging material Fw wound around the cushion roller 21 based on the urging force are provided.

As shown in FIG. 4, the roll support shaft 3a for supporting the packaging material roll Fr in the packaging material roll supporting portion 3 is cantileveredly supported by the frame panel 17. Specifically, the frame panel 17 is a drive device including a roll support shaft 3a of the packaging material roll support portion 3 and a drive motor and a transmission mechanism for rotationally driving the packaging material feed rollers 4a and 4b of the packaging material feed roller unit 4. , And the front panel of the drive box 18 that houses the urging means 24 and the like of the cushion roller portion 5. By supporting the roll support shaft 3a that supports the packaging material roll Fr on the frame panel 17 in a cantilever manner in the packaging material roll support portion 3, the packaging material roll Fr is loaded onto the roll support shaft 3a from the shaft tip side. -It is removable.

The support 22 includes two roller support portions 25 and 26 that rotatably support both ends of the cushion roller 21 on the front side of the frame panel 17. In this example, the roller support portion 25 on the side closer to the frame panel 17 is a thin plate-shaped support portion, and the roller support portion 26 on the side farther from the frame panel 17 is a thick plate-shaped support portion. A paper joint plate 20 is attached between the roller support portions 25 and 26 so as to be bridged. The support 22 also includes an extension 27 extending from the roller support 25 on the side closer to the frame panel 17 to the back side of the frame panel 17 through the frame panel 17. The frame panel 17 is formed with an elongated hole 17a through which the extension portion 27 can move in a direction orthogonal to the rotation axis Lc of the cushion roller 21 (direction indicated by an arrow).

The guide body 23 has at least the tip portions 28a, 29a of the two stays 28, 29 protruding from the front side of the frame panel 17 in a cantilever shape at a predetermined position between the packaging material roll support portion 3 and the packaging material feed roller portion 4. It includes a guide shaft 30 attached between them. The guide shaft 30 extends in a direction orthogonal to the rotation axis Lc of the cushion roller 21, and is slidably fitted with the roller support portion 26 on the side far from the frame panel 17. In this example, the guide body 23 is a round shaft-shaped guide shaft 30, but a sliding rail or a linear motion bearing may be used. The urging means 24 is arranged on the back side of the frame panel 17 between the frame panel 17 and the extension portion 27 of the support 22. Although the urging means 24 is a coil spring in the illustrated example, the urging means 24 is not limited to this, and may be an pneumatic cylinder.

Although the paper joint plate 20 is unitized by being attached to the support 22, the structure of the cushion roller portion 5 is integrated around the support 22 as a whole. That is, the support 22 includes two roller support portions 25 and 26 relatedly arranged on the front side of the frame panel 17, and an extension portion 27 relatedly arranged on the back side of the frame panel 17, and the cushion roller 21 and the guide body 23. The guide shaft 30 and the urging means 24 of the above are associated with these roller support portions 25, 26 or extension portions 27. With such a configuration, the structure of the cushion roller portion 5 is simplified.

The guide body 23 guides the support 22 in a direction orthogonal to the rotation axis Lc of the cushion roller 21, and the urging means 24 exerts the urging force on the support 22. The support 22 that receives the urging force of the urging means 24 is guided by the guide body 23, so that tension is applied to the strip-shaped packaging material Fw that is wound around the cushion roller 21. By connecting the two roller support portions 25 and 26 with a dedicated connecting member and attaching the paper joint plate 20 to the connecting member, the paper joint plate 20 is indirectly attached to the two roller support portions 25 and 26. However, the number of parts can be reduced and the structure can be simplified by using the paper joint plate 20 as a connecting means by directly hanging the paper joint plate 20 between the roller support portions 25 and 26. it can.

A paper holding plate 31 that presses the strip-shaped packaging material Fw onto the paper joint plate 20 is attached to the paper joint plate 20 at a position closer to the cushion roller 21. The paper holding plate 31 has a long plate portion 32 having a length substantially the same as the roller width of the cushion roller 21 when viewed from the rotation axis Lc of the cushion roller 21, and the direction in which the rotation axis Lc extends. Both ends of the long plate portion 32 along the above are bent to form standing pieces 33 and 34.

One end side of the rotation axis Lc in the extending direction, that is, the upright piece 33 on the side close to the roller support portion 25 is rotatably supported by means such as a pin shaft with respect to the paper joint plate 20, and the rotation axis. The other end side in the extending direction of Lc, that is, the upright piece 34 on the side close to the roller support portion 26 is a picking piece. The paper holding plate 31 can be flipped up onto the paper joint plate 20 by picking the upright piece 34, which is a picked piece, and making it around the rotation axis of the upright piece 33. The paper presser plate 31 is rotated on the upright piece 33 side to be flipped up on the paper joint plate 20, and in that state, the vicinity of the end of the strip-shaped packaging material Fw is placed on the paper joint plate 20, and further, the paper presser plate 31 is placed. By pushing down the strip-shaped packaging material Fw onto the paper joint plate 20, the strip-shaped packaging material Fw can be pressed onto the paper joint plate 20 by the long plate portion 32 of the paper presser plate 31. The pressing action of the strip-shaped packaging material Fw on the paper joint plate 20 by the paper pressing plate 31 can be obtained by the own weight of the paper pressing plate 31. Further, instead of changing the weight of the paper presser plate 31, for example, the paper joint plate 20 is provided with a magnet, the paper presser plate 31 is formed of a magnetic material, and the paper presser plate 31 is attracted to the paper joint plate 20 by magnetic force. By doing so, the pressing force may be obtained.
