Description

  The present invention relates to a sachet supply apparatus, and more specifically to an apparatus for supplying a sachet of soup or the like enclosed in a package together with noodles in, for example, instant noodles.

  For example, in instant noodles, it is common practice to enclose a sachet packed with powdered soup stock, liquid soup, spices, dries and the like together with the noodles. As a form of the package, there are various types such as a container such as a cup and a bag depending on the type of noodles to be stored.

  When manufacturing this kind of package, various methods are taken, but an example is disclosed in FIG. In other words, a sachet continuous body formed by connecting sachets in a belt shape is passed over a plurality of rollers so that it is transported along a predetermined transport path, and a pair of feed rollers that sandwich the sachet continuous body from both sides are provided in the transport path The pair of feed rollers are rotationally driven in a state where the sachet continuous body is sandwiched at a predetermined pressure, whereby the rotational force is transmitted to the sachet continuous body and is drawn (conveyed). Furthermore, a cutter is provided in the vicinity of the carry-out side of the conveyance path, and individual sachets are formed by cutting the sachet continuous body at predetermined pitches. The sachets are moved along a predetermined carry-out route, and are sequentially supplied onto a cup noodle container and noodles, and packaged together with the containers and the noodles.

Moreover, as an apparatus which cut | disconnects the desired position (seal part) of a small bag continuous body, there exist some which were disclosed by patent document 2,3. In the invention disclosed in these documents, a thickness detection unit that detects a pouch by a difference in thickness between a storage unit and a seal unit is provided on a path through which the continuous bag is supplied to a cutter, and detection from the thickness detection unit is performed. Based on the signal, the seal portion is cut by a cutter.

  However, the conventional sachet supply device described above has the following problems. That is, as in the invention disclosed in Patent Document 1, when a sachet continuous body is conveyed by a pair of feed rollers, the position of the sachet is specified, and a boundary portion (seal portion) between the front and rear sachets is detected and cut. This requires a separate sensor.

  Further, as in the inventions disclosed in Patent Documents 2 and 3, if the position of the sachet is recognized based on the thickness, a state of cut-out of cutting the storage part due to a false detection is generated, or the storage part is recognized. There is a risk that the pouch cannot be separated without being able to be separated. That is, as for the thickness of the sachet continuum, the sachet is sandwiched between two thickness detection rolls, and the interval between the rolls is detected to determine the seal portion and the storage portion of the sachet continuum. At this time, in order to accurately detect the thickness, the two rolls are always held in a state where they are pressed against each other by being linked by a pressure spring or the like.

  For this reason, for example, when a drying tool material is stored in the storage part of the sachet continuous body, the drying tool material is crushed and broken by the pressure of the roll, and the commercial value is significantly reduced. There is a risk. In addition, in the case of contents that are affected by static electricity or friction with the film forming the sachet continuum, it is diffused in a dense state in the storage part, so even the storage part is as thin as the seal part. There is a place to be. Then, although it is not a proper position, it is erroneously detected as a “position where the seal portion changes from the seal portion”, and there is a risk that a correct cut-off measurement may not be performed and a body cut to cut the storage portion may occur.

  Furthermore, when manufacturing a continuous bag of sachets with a filling machine, wrinkles may occur in the seal portion or the contents may be caught in the seal portion. As a result, a certain amount of thickness is generated even in the sealed portion of the sachet continuous body in the first place, and there is a risk of erroneous detection and accompanying erroneous cutting.

  Furthermore, the sachet continuous body is stored in an appropriately folded state and is sequentially pulled out therefrom. Therefore, if the folded portion is a seal portion, a crease occurs, and it may be determined that the seal portion has a certain thickness while being a seal portion, and may be erroneously recognized as a storage portion. On the other hand, when the folded part is a storage part, a folding fold may arise in the storage part and the thickness of the part may become thin. If it does so, in the thickness detection part, the thinned part will be misrecognized as a seal | sticker part, and there exists a possibility of cutting the thinned storage part with a back | latter stage cutter. Furthermore, the above-mentioned problem occurs more remarkably when the conveyance speed of the continuous pouch is increased.

  The object of the present invention is to solve the above-described problems. The purpose of the present invention is to convey the sachet continuum reliably even if the conveyance speed is increased, guide it to the cutter device, and cut it at a desired position of the sachet continuum. An object of the present invention is to provide a sachet supply device capable of separately producing sachets.

In order to achieve the above-described object, a sachet supply device according to the present invention includes a pulling means for continuously pulling out a continuous sachet made of a strip of continuous sachets enclosing an article, and the sachet drawn by the pulling means. A sachet supply device including a cutting device for cutting between sachets before and after the continuum to separate the sachets, wherein the sachet continuum is provided with holes at a predetermined pitch on at least one side edge; said drawing means includes a drive roller which gives conveying force to the pouch continuum, the driving roller is configured to divide into a plurality of circular circumferentially provided with a plurality of pieces which are movably provided in the radial direction, The outer surface of the small piece is formed in an arc shape to be a surface that comes into contact with the sachet continuous body. The small piece is provided with a through-hole penetrating in the radial direction, and the inside of the through-hole is relatively aligned along the radial direction. Reciprocating Ability to place the projection, the projection is a position where the pouch continuum while being placed insertable located in the hole is away from the driving roller, the amount of protrusion is so reduced.

  By adopting such a configuration, in the present invention, the protrusion provided on the drive roller is hooked by being inserted into the hole provided in the continuous bag. Therefore, as the driving roller rotates, the projection gives a conveying force to the sachet continuous body through the hole, so that the sachet continuous body is transported without delaying (sliding) following the rotation of the driving roller. Therefore, by controlling the rotation of the drive roller, the position of the continuous sachet can be controlled with high accuracy, and the sealing process of the continuous sachet can also be reliably cut by the cutting process in the subsequent cutter device. Furthermore, since the conveyance distance of the continuous bag can be accurately controlled according to the rotation angle of the driving roller, the cutting position can be accurately recognized and cut without providing a special device such as a thickness detector as in the prior art. . Furthermore, a hole having a predetermined pitch is provided in a side edge (vertical seal portion) of the continuous bag body, and a protrusion is inserted into the hole part to give a conveying force to the continuous bag body and to detect a cutting position. For this reason, a special sensor such as a conventional pressure roller is not required, so that no force is applied to the contents and the contents are not crushed. Therefore, the restriction of the contents stored in the sachet continuous body is relaxed.

  In addition, the arrangement pitch of the protrusions on the surface of the driving roller becomes longer as the driving roller 15 becomes larger if the angular interval between adjacent protrusions is constant. Therefore, since the driving roller is composed of a plurality of small pieces and the small pieces can be moved in the radial direction, the arrangement pitch of the protrusions can be changed / adjusted with the movement of the small pieces. Therefore, it becomes possible to deal with a case where the pitch of the through holes formed in the sachet continuous body is different, and the versatility is improved.

Preferably , a pressing roller is provided above the driving roller, and a circumferential groove is provided on the peripheral surface of the pressing roller at a position facing the protrusion, and the groove is continuous over the entire circumference. A side edge of the sachet continuous body is sandwiched between the pressing roller. If it does in this way, a sachet continuum can be certainly held down with a holding roller, and a projection can be inserted in a penetration hole.

Further, the projecting amount of the projection, as shown in the form of implementation, the amount of projection "0", that is, better to be housed in small pieces. The protrusion is reduced at the position where the sachet continuum separates from the drive roller, and the sachet smoothly separates from the drive roller because the protrusion smoothly detaches from the through hole. . In other words, when there is a protrusion in the through hole, the amount of protrusion can be increased, and a conveying force can be reliably applied to the continuous bag.

  Even if the conveyance speed of the sachet continuum increases, the sachet continuum is reliably transported to the cutter device without slipping by the driving roller that applies the conveyance force to the sachet continuous pair, and is guided to the cutter device. The pouch can be separated by cutting at a desired position. And it can respond also to the small bag continuous body from which the pitch of a through-hole differs.

  FIG. 1 shows an example of the overall configuration of a preferred embodiment of the present invention. The sachet supply apparatus 10 according to the present invention is installed on the upstream side of the article transporting device 1 constituting a part of the automatic packaging machine, and on the upper surface of the product 5 conveyed on the article transporting device 1. The pouch 11 is dropped and supplied.

  First, an automatic packaging machine to which the sachet supply device 10 is attached will be described. The packaged article conveying apparatus 1 shown in the figure and a packaging machine main body (not shown) installed on the downstream side of the packaged article conveying apparatus 1 are provided. Configured. As the packaging machine body, for example, a pillow packaging machine can be used, but the present invention is not limited to this. Further, another conveying device may be interposed on the downstream side of the packaged material conveying device 1.

  Further, the packaged article conveying apparatus 1 includes a driving sprocket 2 and a driven sprocket 3 arranged in the front and rear, and an endless chain 4 spanned between the two sprockets 2 and 3. Further, the endless chain 4 is provided with push fingers 7 at predetermined intervals. And the sachet 11 is supplied one by one on the product 5 such as dry noodles in the middle of conveyance placed on the conveyance path surface not shown, and the article 6 to be packaged comprising the product 5 and the sachet 11 is pushed by the finger 7. Is further transported on the transporting road surface and sequentially transferred to the next stage apparatus. Such a basic configuration is the same as the conventional one.

  The sachet 11 is an accessory enclosed with the product 5, and when the product 5 is dry noodles, for example, it is a small package or the like in which a soup as a product is enclosed in the storage portion 11a (see FIG. 2). Of course, the items enclosed in the sachets 11 are not limited to soup, and may be spices, dry foods, etc., or desiccants.

  The sachet 11 is generated by preparing a sachet continuous body 12 in a strip shape as shown in FIG. 2 and cutting and separating the sachet continuous body 12 from the tip of the sachet continuous body 12 one by one. Specifically, the sachet continuous body 12 stored in a state of being folded in the temporary storage container 13 is continuously pulled out and hung on the guide roller 14 and the driving roller 15 arranged at predetermined positions, and the tip thereof is Set so as to guide to the cutter device 16. The sachet continuous body 12 receiving the conveying force from the driving roller 15 is continuously drawn out and guided to the cutter device 16, and the cutter device 16 cuts a predetermined position. As a result, the sachet 11 formed separately is naturally dropped downward and rides on the product 5. Of course, the operation of the packaged article conveying device 1 and / or the small bag supply device 10 is controlled so that the small bag 11 is correctly placed on the product 5, and the cut is performed at the same timing. Therefore, detailed description thereof is omitted.

  Here, in the present invention, as shown in FIG. 2, the sachet 11 (continuous sachet body 12) is formed of a three-sided package with three sides sealed, and a through hole 11b is formed on one side sealed. take. The through-holes 11b are formed at regular intervals in the seal portion on one side edge of the sachet continuum 12. The shape is circular in the present embodiment, but can be a quadrangle, a triangle, or any other shape. Furthermore, instead of a through hole, a cut line such as a U-shape or a circular arc with a predetermined central angle is provided, leaving the film part defined by the cut line in a free state, and pressing the film part to form the hole part. You may make it appear. It is preferable to leave the film portion in this way, because the punched chip piece is not discharged when the side edge of the sachet continuous body 12 is drilled to form a hole.

  Then, as shown in FIG. 3, by inserting (hanging) the protrusion 19 provided on the drive roller 15 into the above-described through hole 11b, the rotational force of the drive roller 15 is reduced through the protrusion 19 and the through hole 11b. The information is transmitted to the continuum 12 so that the sachet continuum 12 is reliably conveyed without slippage at the drive roller 15 portion. The detailed configuration of the transfer device that applies a transfer force to the continuous bag 12 including the drive roller 15 will be described later.

  On the other hand, the cutter device 16 is composed of a pair of left and right cutters 20 arranged with the sachet continuous body 12 interposed therebetween. Each cutter 20 has a configuration in which a cutter blade 23 is attached to the tip of a mounting base 22 installed on a rotating shaft 21 at intervals of 120 degrees. Then, the rotational angle positions of the pair of left and right cutters 20 are matched so that both rotate in synchronization. As a result, each time the rotating shaft 21 rotates 120 degrees, the pair of left and right cutter blades 23 sandwich and seal the sealed portion of the sachet continuous body 12 from both sides thereof with a predetermined pressure. In addition, since the conventionally well-known various things can be used for the structure of the cutter apparatus 16, the detailed description is abbreviate | omitted.

  In the present embodiment, the sachet 11 cut by the cutter device 16 is allowed to fall naturally, but an appropriate shooter (discharge path) is provided, and the sachet 11 moves so as to slide down along the shooter. Various changes can be made such as being transferred onto the product 5.

  Next, the driving device 25 including the driving roller 15 will be described. First, the drive roller 15 is provided with a small piece 30 that is divided into a plurality of pieces in the circumferential direction and is installed so as to be movable in the radial direction. Each of the small pieces 30 is provided with a protrusion 19 so as to be able to protrude and retract, and the surface (outer peripheral surface) 30a of the small piece 30 is formed in an arc shape, and the surface 30a is arranged along the virtual circumference. As a result, the drive roller 15 is configured as a whole. In other words, the individual small pieces 30 are formed by dividing the cylindrical frame into a plurality at equal angular intervals.

  Although the specific mechanism will be described later, as shown in FIG. 3, the protrusion 19 protrudes outward from the surface 30a of the small piece 30 in a section of about 180 degrees in the upper half and small pieces in the section of 180 degrees in the lower half. 30 so as not to protrude from the surface 30a. Thus, when the protrusion 19 enters the small piece 30, the protrusion 19 is detached from the through hole 11 b of the small bag continuous body 12, so that the small bag continuous body 12 is smoothly separated from the drive roller 15.

  Further, in the present embodiment, the small piece 30 is movable in the radial direction. That is, the state shown in FIG. 3 is located on the most central side where the side surfaces of the adjacent small pieces 30 are in contact (adjacent), and from this state, each small piece 30 can move outward within a range of a predetermined distance. ing. It is preferable that the moving distances of the small pieces 30 at this time are all equal. Accordingly, when each small piece 30 is moved outward by a predetermined distance, the surface 30a of each small piece 30 after the movement is arranged on the circumference of a virtual circle having a larger diameter than that shown in FIG. . In addition, since the curvature itself of the surface 30a of the small piece 30 does not change, the surface 30a does not completely coincide with the circumference of the virtual circle having a large diameter. no problem.

  The arrangement pitch of the protrusions 19 on the surface of the driving roller 15 composed of a plurality of small pieces 30 becomes longer as the diameter of the driving roller 15 becomes larger if the angular interval between the adjacent protrusions 19 is constant. Therefore, as the small piece 30 moves as described above, the arrangement pitch of the protrusions 19 becomes longer. That is, the side edge on which the through-hole 11b of the small bag continuous body 12 is formed in contact with the surface 30a of the small piece 30 and the protrusion 19 is inserted into the through-hole 11b so that the conveying force to the small bag continuous body 12 is increased. However, by changing the arrangement pitch as described above, it is possible to cope with a different pitch of the through holes 11b formed in the sachet continuous body 12. Therefore, as shown in FIG. 2, if two through holes 11b are provided in one storage portion 11a, if the length of the storage portion 11a and thus the pouch 11 is different, the pitch of the through holes 11b is also different. However, in the present embodiment, by adjusting the position of the small piece 30 in the radial direction, the present invention can be applied to the continuous bag 12 having a different pitch of the through holes 11b.

  In addition, if the stop position of the small piece 30 is continuously set to an arbitrary position, the pitch of the corresponding through holes is preferably widened, but the stop position may be made discrete. The number of stopping points in the case of being discrete is arbitrary, and may be one that reciprocates between two different stopping positions. Of course, it is good also as three or more places.

  Further, in the present embodiment, a restraining roller 32 is provided above the driving roller 15. A concave groove 32 a is formed in the center of the circumferential surface of the pressing roller 32, the concave groove 32 a faces the protrusion 15, and both surfaces of the pressing roller 32 are on the surface 30 a of the small piece 30 constituting the driving roller 15. It arranges so that it may touch. Further, the holding roller 32 is rotatably arranged with respect to the lower end of the L-shaped plate 70. The L-shaped plate 70 can be rotated forward and backward about a rotation shaft 71 provided at a bending point, and a projecting piece 72 is connected to the upper end thereof. A photomicrosensor 73 is arranged at a position where the protrusion 72 can be detected.

  As a result, a force that moves the restraining roller 32 downward is applied from the weight of the restraining roller 32 and the balance of the L-shaped plate 70 so that the L-shaped plate 70 rotates counterclockwise in FIG. Be energized. Therefore, the one side edge of the sachet continuous body 12 is sandwiched between the pressing roller 32 and the driving roller 15 (small piece 30) from the upper and lower sides with a predetermined force. That is, the restraining roller 32 urges the sachet continuum 12 downward (drive roller 15) to suppress the sachet continuation body 12 from being lifted, so that the sachet continuum 12 is pushed up by the protrusion 19. Even if such an action is applied, if the deviation between the projection 19 and the through-hole 11b is small, the continuous bag 12 is conveyed while being sandwiched between the rollers 15 and 32 by the action of the restraining roller 32. 19 is also reliably guided into the through hole 11b.

  When the relative position between the protrusion 19 and the through-hole 11b is greatly shifted and the protrusion 19 is not inserted into the through-hole 11b by the downward biasing force of the above-described suppression roller 32, the suppression roller 32 is protruded by the small bag continuous body 12. It will be lifted upward by the height of 19. Then, as the restraining roller 32 rises, the L-shaped plate 70 rotates clockwise in FIG. 4, and the projecting piece 72 also rises. This rise is detected by the photomicrosensor 73 and notified to the skull control device. As a result, the control device that has received such notification determines that it is abnormal, stops the device, and issues an alarm.

  Furthermore, a feed brush 35 is disposed at a lower position near the carry-out side of the drive roller 15. As the feed brush 35 rotates, the continuous sachet 12 in contact with the peripheral surface is biased downward, so that the continuous sachet 12 is reliably supplied to the cutter device 16 directly below.

  Next, a specific configuration of the driving device 25 including the driving roller 15 for realizing the above-described function will be described. As shown in an enlarged view in FIGS. 4 to 6, the driving device 25 mounts a bearing portion 42 in a through hole 41 a penetrating front and rear (plate thickness direction) at a predetermined position of the side wall 41, and rotates on the bearing portion 42. The rotating shaft 43 is freely attached. Both ends of the rotating shaft 43 protrude from the bearing portion 42, and the driven pulley 44 is connected to an end portion protruding to the rear side of the side wall 41. The driven pulley 44 is linked to a drive pulley 47 attached to the output shaft of the drive motor 46 via the power transmission belt 45, and the driven pulley 44 and thus the rotating shaft 43 rotates as the drive motor 46 rotates. Further, a tension pulley 48 is linked to the outside of the power transmission belt 45 to give a predetermined tension to the power transmission belt 45 and to prevent the power transmission belt 45 from being detached from the driving and driven pulleys 47 and 44. Suppress.

  On the other hand, a rotating plate 51 is connected to a portion protruding to the front side of the rotating shaft 43 via an annular connecting member 50, and the rotating plate 51 is also rotated integrally with the rotating shaft 43. In the rotating plate 51, a plurality of base members 52 are arranged at equiangular intervals on the center side of the front surface. The number of base members 52 is made to match the number of small pieces 30. The small piece 30 is coupled to the base member 52 via a support shaft 53. The support shaft 53 is a rod-like body having a male screw formed around it, and can be constituted by a bolt. One end of the support shaft 53 is connected to the base member 52 and the other end is connected to the small piece 30.

  At this time, the support shaft 53 is disposed along the radial direction, and the connection between one end of the support shaft 53 and the base member 52 is fixed by a nut 57 attached to the support shaft 53. That is, since the inner diameter of the through hole provided in the base member 52 is set larger than the outer shape of the support shaft 53, the support tool 53 can be moved in the rotational direction and the axial direction in the state where the support tool 53 is inserted into the through hole. It has become. Therefore, a nut 57 (in this embodiment, a bolt is used for the support shaft 53 in this embodiment, so that the nut at the tip is a bolt head 53a) is attached to both sides of the base member 52 so as to be positioned on both sides. The base member 52 is sandwiched between them and fixed. Further, a rotation-preventing nut 57a is provided on the outer side of the nut 57 attached to the small piece 30 side of the support shaft 53 so that the nut 57 does not shake during operation.

  On the other hand, the other end of the support shaft 53 and the small piece 30 are connected by fastening a female screw portion 30 b provided on the small piece 30 and a male screw formed on the support shaft 53. Accordingly, by rotating the support shaft 53 (bolt) forward and backward, the female screw portion 30 b and thus the small piece 30 can move forward and backward along the support shaft 53, that is, move in the radial direction of the drive roller 15. Further, a rotation-preventing nut 57a is also attached to the female screw portion 30b side of the support shaft 53 to prevent the support shaft 53 from rotating and moving the small piece 30 due to vibration generated during operation of the apparatus.

  Thus, in the present embodiment, by rotating the support shaft 53 forward and backward, the small piece 30 can be moved in the radial direction and can be fixed at an arbitrary position. The position adjustment needs to be performed for each small piece 30. Although not shown, for example, by providing a scale for alignment on the small piece 30 side that moves in the radial direction and the rotary plate 51 side that does not move in the radial direction, the position of each small piece 30 is easily aligned. be able to.

  As shown in FIGS. 5 and 6, the small piece 30 is in contact with the front surface of the rotating plate 51 and is connected and integrated through a support shaft 53 and a base member 52. Accordingly, as the rotating plate 51 rotates, the small piece 30 also revolves, and the protrusion 19 attached to the small piece 30 revolves together with the small piece 30 so as to give a conveying force to the small bag continuous body 12. become.

  On the other hand, the radial movement (protrusion and protrusion from the surface 30a of the small piece 30) of the protrusion 19 associated with the revolution is as follows. That is, the protrusion 19 has a thin rod shape with a thin tip, and is inserted and arranged so as to be movable in the axial direction (diameter when viewed from the drive roller 15) in the through hole 30c that penetrates the small piece 30 in the radial direction. . The tip end of the protrusion 19 can protrude from the surface 30 a of the small piece 30, and the base end side of the protrusion 19 is set to always protrude from the back surface side of the small piece 30.

  Further, a window hole 51b is opened at a predetermined position near the base end side of the protrusion 19 of the rotating plate 51, and a connecting rod 54 is disposed so as to cross the window hole 51b, and one end (the rotating plate) of the connecting rod 54 is disposed. The lower end of the protrusion 19 is connected to the front side 51. The other end of the connecting rod 54 is connected to one end of a connecting plate 55 that is arranged in parallel with the rotating plate 51 at a predetermined interval. The connecting plate 55 is connected to the cam floor 58. The disc-shaped plate cam 56 provided with the cam groove 56a with which the cam floor 58 coincides is fixed to a bearing portion 42 provided on the side wall 41 (mounted with a rotating shaft 43 to which the rotating plate 51 is connected). .

  As a result, when the rotating shaft 43 rotates, the rotating plate 51 also rotates together, so that the cam floor 58 rotates together with the protrusion 19, the connecting rod 54, and the connecting plate 55, but the plate cam 56 does not rotate. Therefore, the cam floor 58 moves along a locus along the cam groove 56a. That is, since the cam groove 56a formed at a position away from the center passes through the upper half side, the protrusion 19 is also positioned on the outer side in the radial direction, and the tip of the protrusion 19 protrudes outward from the surface 30a of the small piece 30. .

  On the other hand, on the lower half side, the cam floor 58 moves to the center side relatively abruptly along the shape of the cam groove 56a, and then gradually moves outward over about a half circumference. Therefore, the protrusion 19 also operates so as to gradually protrude after entering the inside from the surface 30a of the small piece 30 once.

  Further, in the present embodiment, a guide mechanism 59 is provided between the connecting plate 55 and the back surface of the rotating plate 51 to guide the movement of the connecting plate 55 in the radial direction in order to stably operate the trajectory described above. I am doing so. That is, a guide rail 59a extending in the radial direction is disposed at a predetermined position on the back surface of the rotating plate 51, and the slider 59b that straddles the guide rail 59a and reciprocates along the rail is fixed to the connecting plate 55. Accordingly, the slider 59b is guided by the guide rail 59a and moves in the radial direction, and the separation is suppressed, so that the connecting plate 55 can be stably moved in the radial direction.

  Further, a guide plate 65 is provided in front of the rotating plate 51 so as to cover the periphery of the driving roller 15 and the like. The guide plate 65 has a shape in which both ends of a belt-like flat plate are curved downward, and the surface of the guide plate 65 constitutes the conveyance surface of the sachet continuous body 12.

  One side edge of the guide plate 65 becomes a concave notch portion 65a with the tip side notched in a concave shape, and the concave notch portion 65a is installed while being positioned above the small piece 30 (drive roller 15). Thereby, the small piece 30 which came upwards protrudes upwards from the concave notch part 65a, and supports the side edge of the small bag continuous body 12. FIG.

  Further, the guide plate 65 is formed by integrally forming a front panel plate 66 and a rear panel plate 67. Both the front panel plate 66 and the rear panel plate 67 protrude upward from the surface of the guide plate 65 and are in contact with or close to both side edges of the sachet continuum 12, thereby suppressing lateral shaking of the sachet continuum 12. The front end 43a of the rotary shaft 43 is rotatably supported by a bearing 66a provided on the back side of the front panel plate 66, and the connecting rod 68 passed between the front panel plate 66 and the side wall 41 is bolted. As a result, the front panel plate 66 and thus the guide plate 65 and the rear panel plate 67 are fixed to the side wall 41.

  In the embodiment described above, the tip shape of the protrusion is hemispherical. However, the present invention is not limited to this, and various three-dimensional shapes such as a triangular pyramid and a cylinder can be adopted. It is also possible to make the through hole easy to be caught by bending the tip, such as a letter shape or a square shape. Furthermore, in the above-described embodiment, a through hole (hole) is provided on one side edge of the sachet continuous body. However, the present invention is not limited to this and may be provided on both sides.
