Description

  The present invention relates to a horizontal pillow packaging machine, for example, a horizontal pillow packaging machine for packaging coffee drip bags and the like.

  There is a drip bag that allows you to easily enjoy the taste of authentic drip coffee. Such a coffee drip bag includes a non-woven bag filled with a cup of coffee powder and a support member for supporting the bag with the edge of the cup. And the drip bag which concerns is enclosed with the outer bag formed with packaging films, such as an aluminum vapor deposition film. Thus, when manufacturing the package enclosed by the outer bag, conventionally, a vertical pillow packaging machine is used like the double packaging apparatus disclosed by patent document 1, for example.

JP2014-108818 Patent 3760266

  The vertical pillow packaging machine has a problem that the number of manufactured units per unit time cannot be increased too much. Therefore, it was considered that the drip bag is packaged by using a horizontal pillow packaging machine that can cope with an increase in processing speed instead of the vertical pillow packaging machine.

  The horizontal pillow wrapping machine arranges a packaged article transport and supply device on the upstream side of the bag making machine, conveys the packaged article at regular intervals on the packaged article transport and supply apparatus, and sequentially forms the packaged article into the bag making machine. It is configured to be wrapped in a packaging film that is supplied to the inside and supplied separately to the bag making machine. In the case of packaging a drip bag, the drip bag becomes an article to be packaged, and a finger conveyor apparatus or a belt conveyor apparatus is used as the article transporting and supplying device.

  For example, when a belt conveyor device is used, the following problems occur. That is, the drip bag is a non-woven bag and is slippery. Therefore, if the conveyance speed is increased in order to increase the number of products manufactured per unit time, the drip bag moves relatively back and forth on the belt conveyor, and the relative movement distance cannot be ignored when the conveyance distance becomes long. As the position is shifted, the sheet cannot be supplied to a desired position where there is no packaging film, and there is a risk of biting in the top seal device at the subsequent stage.

  On the other hand, when the finger conveyor device is used, the transport pitch of the drip bag is the front and rear finger pitch, and the drip bag is supplied to the bag making device at regular intervals. However, as a form of drip bag, for example, as disclosed in Patent Document 2, there is a type in which a hook made of cardboard is attached to a side surface of a non-woven bag body as a support member, and a perforation for opening is formed. If the upper side is transported upstream, the bag body will bend at the perforation when pushed by the fingers, causing displacement of the packaging film, and as a result, causing the bite during sealing in the packaging machine body Become.

  In order to solve the above-described problems, the horizontal pillow packaging machine of the present invention includes (1) a packaging machine body having a horizontal conveying surface, a film supply device for supplying a packaging film to the packaging machine body, A horizontal pillow packaging machine provided with a packaged article transport and supply device for supplying a packaged article to the packaging machine body, wherein the packaged article transport and supply device includes a belt conveyor device that conveys the packaged article; A positioning device disposed above the belt conveyor device, the positioning device moving on the transport surface of the belt conveyor device in the same direction as the transport direction of the packaged object, and a reference position And a moving mechanism for moving the blade member, and the moving speed of the blade member is set to be slower than the conveying speed of the belt conveyor device. The articles to be packaged for moving the belt conveyor apparatus above, configured to be positioned in contact with the blade member located in front. In the embodiment, the moving mechanism corresponds to the endless chain 45 or the like hung around the sprocket 44.

  Since the object to be packaged is conveyed by the belt conveyor device, even if the object to be packaged is easily depressed or deformed when pressed from the periphery, it can be conveyed without being deformed. And since the conveyance speed of a belt conveyor apparatus is faster than the moving speed of a blade member, it catches up with a blade member and the front end of a to-be-packaged product contacts the blade member located ahead. In a state where the blade member is in contact with the blade member, the conveyance speed of the package is the moving speed of the blade member. When the blade member reaches the reference position, the blade member separates from the conveying surface, and accordingly, the blade member also separates from the packaged object. Then, after the reference position, the conveyance speed of the article to be packaged results from the conveyance speed of the belt conveyor device. Therefore, since the blade member separates at the reference position, the article to be packaged is positioned at the reference position at the reference position. The objects to be packaged positioned in such a manner are conveyed from the reference position by the belt conveyor device, and sequentially supplied to the packaging machine body at the next stage at a predetermined timing. Since the article to be packaged is positioned at the reference position on the belt conveyor device, it is supplied without being displaced with respect to the packaging machine body and thus the packaging film. Can be prevented. In particular, if the reference position is set in the vicinity of the carry-out side of the belt conveyor device and the distance from the reference position to the carry-in position of the packaging machine body is shortened, the effect may be further improved. Moreover, although the force to which the packaged goods which move a belt conveyor apparatus apply from the outside when the front-end | tip contacts a front blade member, the force is the movement speed of a blade member, the conveyance speed of a belt conveyor apparatus, and This is based on the difference in speed of, for example, smaller than the case where the object to be packed is pushed from behind with a pushing finger or the like, and the object to be packed is not crushed at the time of the contact, or even if there is a slight amount Amount. Therefore, the article to be packaged is conveyed without being deformed.

  (2) A first stopper member that protrudes rearward is provided below the rear surface in the moving direction of the blade member, and the upper surface of the tip of the article to be packaged that contacts the blade member is the first stopper member. It is good to comprise so that it may be in the state which contacted the lower surface and the front-end | tip of the said to-be-packaged item lifts upwards beyond it. The first stopper member corresponds to the stopper member 53 in the embodiment. In this case, for example, when an object to be packaged conveyed by the belt conveyor device comes into contact with the front blade member, it may hit with force, or may receive a conveying force from the belt conveyor device after contact. Even if the front end of the package is about to move up along the blade member, the movement can be suppressed by the first stopper member, and positioning of the package can be performed with high accuracy.

  (3) The lower end of the blade member may have a portion located outside the belt surface of the belt conveyor device, and a protrusion projecting downward from the belt surface may be provided in the portion. If it does in this way, the site | part which provided the said protrusion has a blade member in the upper and lower sides of a belt surface. Therefore, positioning can be reliably performed by the packaged object contacting the portions where the blade members are present above and below the belt surface. Even if the shape of the article to be packaged is thin, such as a flat shape, and there is a gap between the belt surface and the lower end of the blade member, there is a risk of entering the gap. Positioning can be performed by preventing entry into the gap.

  (4) A finger conveyor device is provided on the upstream side of the belt conveyor device, and the article to be packaged is transported by the pushing fingers of the finger conveyor device in contact with the rear surface thereof, and delivered to the belt conveyor device. Good.

  (5) The packaged object is a drip bag, and the opening perforation formed in the bag body of the drip bag may be conveyed in a posture toward the upstream side. If it does in this way, since the bottom part side of the bag body which is filled with the contents firmly and is not easily deformed will contact the blade member, it is possible to prevent deformation of the packaged item more reliably and to perform positioning.

  (6) A support member for supporting the drip bag on the cup when the drip bag is used is affixed to the surface of the bag body. It is preferable to provide a second stopper member that protrudes toward the second stopper member so that the article to be packaged can be further prevented from approaching the blade member while the support member is in contact with the second stopper member. The support member corresponds to the hook member 4 of the embodiment. The second stopper member corresponds to the stopper member 53 in the embodiment. When both the first stopper member of the invention of (2) and the second stopper member of the present invention are mounted, it may be realized by one stopper member 53 as shown in the embodiment, or may be formed by another member. May be. When the second stopper member is provided as in the present invention, the article to be packaged does not approach the blade member any more when the support member comes into contact with the second stopper member, so that positioning can be performed.

  According to the present invention, even if the article to be packaged is an unstable product that is easily deformed by an external biasing force, for example, it can be supplied to the packaging film at an accurate position, such as when sealing in the packaging machine body. Biting of the product can be prevented.

  DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. It should be noted that the present invention is not construed as being limited thereto, and various changes, modifications, and improvements can be made based on the knowledge of those skilled in the art without departing from the scope of the present invention.

  As shown in FIG. 1 and the like, the horizontal pillow wrapping machine 10 of the present embodiment includes a wrapping machine main body 11, a film supply device 12 that continuously supplies a belt-shaped wrapping film to the wrapping machine main body 11, It is provided on the upstream side of the packaging machine main body 11, and is provided with a packaged article transport and supply device 14 that supplies the packaged article 1 to the packaging machine main body 11 at predetermined intervals.

  In this embodiment, the package 1 is a coffee drip bag and includes a hook-type support member. That is, as shown in FIG. 2A, the package 1 includes a bag body 3 filled with coffee powder 2 and a hook member 4 attached to a side surface of the bag body 3. The bag 3 is made of non-woven fabric, filled with coffee powder 2 in a state where one side (the upper part in use, the left side in FIG. 2) is opened, and in that state, the one side part is heat-sealed or the like. A seal portion 3a is formed and sealed. Further, an opening perforation 5 is formed at an unsealed portion along the seal portion 3a. Further, when the coffee powder 2 is filled in the bag body 3, the coffee powder 2 is supplied into the bag body 3 from the opening portion with one side to be opened up. Therefore, the coffee powder 2 is filled relatively densely in the posture at the time of supply, that is, the bottom 3b side of the bag body 3 in use. As a result, as shown in FIG. 2 (b), the bottom 3b side is relatively thick, has a certain degree of hardness, and is relatively difficult to be crushed. On the other hand, the thickness of the bag 3 on the side of the perforation 5 is reduced and the coffee powder 2 is also present in a relatively sparse state, and is easily crushed and deformed when an urging force is applied from the outside. At the time of use, the bag body is opened by cutting the perforation 5 prior to the drip, and the hook member 4 is used to set the bag body. In this way, the overall shape of the article 1 to be packaged is a flat shape with a rectangular plane.

  As shown in FIG. 2 (c), the packaged article 1 is hermetically housed in the flat outer bag 6 to produce a package 28. The outer bag 6 is formed from a packaging film such as an aluminum vapor deposition film, and one side of the rectangular shape is folded, and the remaining three sides are sealed (side seal portion 6a, top seal portion 6b) to be sealed. Further, in the present embodiment, there is not much difference between the cut dimensions in the horizontal pillow packaging machine, that is, the length t1 of the outer bag 6 and the length t2 of the package 1 (drip bag), and the top seal portion 6b is considered. Then, there is no dimensional allowance in the front-rear direction and the conveyance direction during the wrapping paper processing.

  The film supply device 12 links the output of a drive motor (not shown) such as a servo motor (not shown) to a raw roll 16 obtained by winding a belt-like film 15 such as an aluminum vapor deposition film into a roll, The roll roll 16 is supplied to the packaging machine body 11 at a constant speed while appropriately controlling the rotation speed of the roll 16. Various rollers 17 are arranged at predetermined positions from the original fabric roll 16 to the packaging machine main body 11, and the belt-like film 15 fed out from the original fabric roll 16 is stretched over the rollers 17, thereby providing a predetermined path. It is guided to the packaging machine main body 11 through. In the present invention, it is not always necessary to link the drive motor to the original fabric roll 16, and a feed roller may be provided on the transport path of the packaging film and pulled out.

  Although the specific configuration will be described later, the packaged article transport and supply device 14 conveys the above-described packaged articles 1 in a state of being arranged in two horizontal rows, and the two packaged articles 1 arranged side by side, At the same time, it is supplied to the packaging machine body 11 at the next stage.

  The packaging machine main body 11 includes a bag making device 20 that sets the strip-shaped film 15 supplied upstream thereof into a cylindrical shape. By passing through the bag making device 20, the belt-like film 15 is lifted so that both side ends are curved upward along the bag making device, and is produced in a cylindrical shape. At this time, both side edges 15a of the belt-like film 15 are set to be close to each other in a non-contact manner while being positioned on the upper center side (see FIG. 4). That is, in the case of a normal pillow packaging machine, both side edges of the strip-shaped film 15 formed into a cylindrical shape overlap each other with sealable surfaces, but in this embodiment, both side edges 15a are respectively cylindrical. It is made to oppose the center part of the strip | belt-shaped film 15 bag-formed in the shape. Moreover, the packaged article conveyance supply device 14 sequentially supplies the packaged articles 1 conveyed in two rows to the bag making machine 20. Thereby, the both-sides end which the strip | belt-shaped film 15 turned up covers the upper direction of each to-be-packaged object 1, respectively.

  On the downstream side of the bag making machine 20, a conveyance path 22 that constitutes a conveyance surface of the cylindrical film 21 that encloses the article 1 to be packaged is disposed. A pinch roller 23, a side seal device 24, and a vertical cutter device 25 are arranged from the upstream side at an appropriate position in the center of the conveyance path 22. The pinch roller 23 is composed of a pair of upper and lower rollers, and sandwiches both side edges 15a of the strip-shaped film 15 formed in a cylindrical shape and the central portion of the strip-shaped film 15 facing it with a predetermined pressure from above and below to form a cylindrical shape. A conveying force is applied to the band-shaped film 15 that has been formed.

  The side seal device 24 is located on the upper side of the strip-shaped film 15 formed in a cylindrical shape, and has a single large side disk-shaped side sealer 24a and the lower side of the strip-shaped film 15 formed in a cylindrical shape. And is composed of two small disc-shaped holding rollers 24b (arranged in the front-rear direction). The side sealers 24a and the restraining rollers 24b arranged on the upper and lower sides sandwich the side edges 15a of the strip-shaped film 15 formed in a cylindrical shape and the central portion of the strip-shaped film 15 opposite to each other with a predetermined pressure from above and below. At the same time, it is heated at a predetermined temperature. Thereby, the both side edge 15a is heat-sealed to the film part which each opposes, and the said sealed part turns into the side seal part 6a. Further, the side edges 15a are respectively sealed by the side seal portion 6a, so that two cylindrical films 21 connected to the left and right are formed from one strip-shaped film 15 which is packed into a large cylindrical shape. become. And the to-be-packaged object 1 is included in these two cylindrical films 21, respectively.

  The vertical cutter device 25 is for cutting the central portion of the side seal portion 6a, that is, between the two tubular films 21 connected to the left and right, and a slit cutter 25a located on the upper side of the tubular film 21; It is comprised from the receiving blade 25b located in the downward side of the cylindrical film 21. FIG. The side seal portion 6a is sandwiched from above and below with a predetermined pressure by the slit cutter 25a and the receiving blade 25b disposed above and below. Thereby, the side seal part 6a is cut along the traveling direction of the film, and the left and right tubular films 21 are separated.

  On the downstream side of the vertical cutter device 25, while supporting the separated two tubular films 21, a conveyor belt 26 to be transported, and an article restraining belt device 30 is disposed above the conveyor belt 26, and A top seal device 27 and a carry-out conveyor 29 are disposed on the downstream side thereof.

  The top seal device 27 seals and cuts the tubular film 21 in a direction orthogonal to the traveling direction, that is, in a transverse direction. The film part to be sealed / cut is a predetermined position between the front and back objects 1 and the top seal portion 6b is formed at the part. Thereby, the top part of the cylindrical film 21 is separated from the succeeding part by passing through the top seal device 27, and the package 28 is manufactured. The manufactured package 28 is carried out by a carry-out conveyor 29. Further, since the left and right tubular films 21 are supplied to the top seal device 27, two packaging bodies 28 are manufactured.

  The to-be-packaged material restraining belt device 30 is arranged in the immediate vicinity of the upstream side of the top seal device 27, suppresses the to-be-packaged material 1 in the tubular film 21 from being lifted upward, and is conveyed while maintaining a horizontal state. I can do it. The to-be-packaged article restraining belt device 30 has a configuration in which an endless belt 62 is stretched around a pulley 61 arranged at the front and rear.

  A packaged article transport and supply device 14 that supplies two packages 1 to the packaging machine body 11 at a desired timing includes a finger conveyor device 31 and a belt conveyor device disposed on the downstream side of the finger conveyor device 31. 32 and an alignment device 33 disposed above the belt conveyor device 32. The finger conveyor device 31 includes sprockets 34 arranged in the front and rear and other predetermined positions, an endless chain 35 spanned over the plurality of sprockets 34, and a pushing finger 36 attached to the endless chain 35 at a constant interval. . A transport path 38 is disposed above the endless chain 35, and the distal end side of the pushing finger 36 projects forward along the transport path 38 as the endless chain 35 rotates while projecting above the transport path 38. . In addition, the articles to be packaged 1 are supplied one by one onto the conveyance path 38 between the front and rear push fingers 36 by a not-shown article supply apparatus. At this time, the article to be packaged 1 is set on the conveyance path 38 with the perforation 5 facing upstream.

  As a result, as shown in FIG. 5, the article 1 to be packaged placed on the conveyance path 38 is attached with the seal portion 3a which is the peripheral edge on the perforation 5 side on the push finger 36 located on the rear side in the conveyance direction. As the push finger 36 moves forward, the article 1 to be packaged is also pushed forward, and moves forward in two rows in a posture with the bottom 3b of the bag 3 facing forward toward the downstream side.

  Further, as shown in an enlarged view in FIG. 6, the downstream end of the transport path 38 is positioned near the upstream end of the next stage belt conveyor device 32. As a result, when the article 1 to be packaged fed by the push finger 36 reaches the downstream carry-out end of the finger conveyor device 31, the leading end side moves to the belt conveyor device 32 side so as to be pushed out by the push finger 36, and the belt The conveying force from the conveyor device 32 side is also received. Then, when the push finger 36 reaches the downstream end of the finger conveyor device 31, the push finger 36 gradually moves downward and separates from the article 1 to be packaged. When separated, the article to be packaged 1 is transferred to the belt conveyor device 32, and moves forward in response to the conveying force from the belt conveyor device 32.

  The belt conveyor device 32 includes a pulley 40 provided at appropriate positions on the front and rear sides, and an endless belt 41 stretched over the pulley 40. The drip bag which is the article to be packaged 1 is conveyed in a posture in which the direction having the perforation 5 for opening is directed upstream as the endless belt 41 rotates. In addition, the conveying speed of the belt conveyor device 32 is set to be approximately equal to or slightly higher than the film conveying speed (the moving speed of the belt-like film 15 supplied to the bag making machine 20) in the subsequent packaging machine body 11. ing. For example, when the conveyance speed of the film and the conveyance speed of the article to be packaged 1 in the belt conveyor device 32 are equal, when the article to be packaged 1 is transferred from the belt conveyor device 32 to the belt-like film 15 that is moving in the bag making machine 20. Although it can be performed smoothly without applying stress to the article 1 to be packaged, in this embodiment, by slightly increasing the conveying speed in the belt conveyor device 32, the article 1 to be packaged is more reliably placed on the packaging machine body 11 side. I handed it over.

  The alignment device 33 includes a sprocket 44 provided at a predetermined position before and after the space above the belt conveyor device 32, an endless chain 45 spanned over the sprocket 44, and a blade member 46 attached to the endless chain 45 at regular intervals. Is provided. As shown in FIG. 8, the endless chain 45 is disposed on both the left and right sides in the conveyance direction of the package 1, and connects both ends of the base bar 50 so as to span the pair of left and right endless chains 45. The base bar 50 is an elongated plate, and the blade member 46 is connected to the base bar 50 via the L-shaped plate 51. The blade member 46 has a flat plate shape and is positioned on a vertical surface and hangs down in a section where the blade member 46 moves along the conveyance direction of the package 1.

  At both the left and right ends of the lower end of the blade member 46, a projecting piece 46a projecting downward is formed, and a shallow recess 46b is formed between the left and right projecting pieces 46a. The width of the recess 46 b is made wider than the belt width of the endless belt 41. In the section where the blade member 46 moves along the endless belt 41, the endless belt 41 enters the recess 46 b, and the left and right projecting pieces 46 a are below the belt surface of the endless belt 41, that is, the conveyance surface of the package 1. It moves forward while maintaining the position located at.

Further, a concave notch 46 c is provided upward at the central portion of the lower end of the blade member 46. The notch 46c is for avoiding interference with the pushing finger 36 of the finger conveyor device 31. That is, for example, when the feeding finger 36 of the finger conveyor device 31 delivers the package 1 to the belt conveyor device 32,
Even if the blade member 46 overlaps with the push finger 36 in the front-rear direction, the push finger 36 is located in the notch 46c of the blade member 46 so as not to contact.

  Furthermore, the moving speed of the blade member 46 in the alignment device 33 is slower than the conveying speed of the article 1 in the belt conveyor device 32. As a result, as shown in FIG. 6, the package 1 is separated from the front blade member 46 by a predetermined distance immediately after being delivered onto the belt conveyor device 32, and as the belt conveyor device 32 is conveyed. When the distance from the front blade member 46 approaches and reaches the vicinity of the carry-out side of the belt conveyor device 32, the leading end (the bottom 3 b side of the drip bag body 3) of the package 1 is the front blade member 46. To touch. In a state where the blade member 46 is in contact with the blade member 46, the article 1 is conveyed at the moving speed of the blade member 46.

  As shown in FIG. 7, when the blade member 46 moves upward and separates from the package 1, the package 1 moves at the conveying speed of the belt conveyor device 32, and the packaging machine body 11 (bag making machine 20). To be supplied. As the endless chain 45 rotates, the blade member 46 rises and separates from the article 1 to be packaged. Therefore, the position (reference position) at which the blade member 46 separates from the article 1 is determined. The positional relationship is also uniquely determined. Therefore, the packaged object 1 at the position where the blade member 46 is separated is, for example, the distance to the bag making machine 20 is constant, and moves from the position at the conveying speed of the belt conveyor device 32 to the bag making machine 20. It is fed into the strip film 15. This is the same for all the objects to be packaged 1 that are conveyed one after the other.

  Therefore, the article 1 to be packaged is brought into contact with the blade member 46 once to be aligned with the front reference, and after being aligned, is supplied to the packaging machine body 11 at the same timing. Therefore, by adjusting the operation timing of, for example, the top seal device 27 in the packaging machine main body 11 and the position of the belt-like film 15 supplied to the packaging machine main body 11 to the position / timing at which the blade member 46 is separated from the package 1. The package 28 can be produced without causing the package 1 to be displaced and without biting the package 1.

  In particular, in this embodiment, since the bottom 3b side of the bag body 3 filled with the coffee powder 2 and having a stable shape is brought into contact with the blade member 46, the packaged article 1 comes into contact with the blade member 46. In addition, the package 1 is difficult to be deformed, and misalignment due to the deformation hardly occurs.

  Furthermore, in this embodiment, since the protruding piece 46a is positioned below the belt surface of the endless belt 41, the article 1 can be reliably brought into contact with the blade member 46 and positioned. In other words, the lateral width of the package 1 with respect to the conveying direction is wider than the belt width of the endless belt 41. Even if a gap is generated between the recess 46b and the endless belt 41, the article 1 to be packaged is in contact with at least the left and right end portions of the blade member 46 and positioned.

  Furthermore, in this embodiment, the time for which the article to be packaged 1 is in contact with the blade member 46 is shortened, the positioning is performed instantaneously, and the belt conveyor device 32 returns to the conveyance. In order to do this, the speed difference between the conveying speed of the belt conveyor device 32 and the moving speed of the blade member 46 is appropriately adjusted, and the belt conveyor device 32 is conveyed just before the position where the blade member 46 is separated. The to-be-packaged product 1 catches up with the blade member 46 so that the tip contacts.

  Furthermore, in this embodiment, the drive motor of the belt conveyor device 32 is provided separately from the alignment device 33 and the drive motor on the packaging machine body 11 side, and is operated based on an independent drive source. This is because, as described above, fine adjustment is necessary for the speed difference adjustment, and it is difficult to deal with mechanical adjustments such as gear ratio. Yes.

  Furthermore, the position at which the blade member 46 is separated from the article to be packaged 1 is close to the bag making apparatus 20, that is, near the carry-out side of the belt conveyor device 32. It is good to be supplied in 20.

  Although the conveying speed by the belt conveyor device 32 is made faster than the moving speed of the blade member 46, it is preferable that there is not much difference in speed. By reducing the speed difference, the stress applied to the article 1 when the article 1 comes into contact with the blade member 46 can be reduced. However, if the speed difference is small, it is necessary to lengthen the moving distance of the belt conveyor device 32, resulting in an increase in the size of the device. Therefore, the speed difference is appropriately set in consideration thereof.

  Furthermore, in this embodiment, a stopper member 53 that protrudes rearward is provided below the rear surface of the blade member 46. The stopper member 53 is formed of a thick L-shaped member and has a shape in which a lower end protrudes rearward. And the lower surface of the part which protruded becomes the 1st locking surface 53a, and the rear surface becomes the 2nd locking surface 53b.

  The first locking surface 53 a forms a certain gap with the belt surface of the endless belt of the belt conveyor device 32, and in a state where the tip of the package object 1 is in contact with the blade member 46, The tip, that is, the bottom 3b of the bag 3 is positioned within the gap. Thereby, when the bottom part 3b of the said bag body 3 tries to lift upwards, the bottom part 3b contacts the 1st locking surface 53a, and prevents a raising.

  The second locking surface 53b can contact the hook member 4 of the article 1 that has moved forward. That is, for example, the conveying force from the belt conveyor device 32 is large, and even after the tip of the article to be packaged 1 comes into contact with the blade member 46, the tip of the article 1 to be packed is crushed. In such a case, the hook member 4 comes into contact with the second locking surface 53b, and further relative forward movement is suppressed. Thereby, it is suppressed as much as possible that the bottom part 3b side of the bag 3 is crushed.

  In the embodiment described above, the package 1 is transported with the bottom 3b side of the bag body 3 as the front side, but the transport posture of the package 1 is reversed front and back, and the side where the perforation 5 is formed is transported forward. You may make it do.
