Description

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

  There is a drip bag designed to make it easy to drink the taste of authentic drip candy. The coffee drip bag comprises a non-woven bag filled with a cup of coffee powder and a support member for supporting the bag at the edge of the cup. And such a drip bag is enclosed in the outer bag formed with packaging films, such as an aluminum vapor deposition film. Thus, when manufacturing the package body enclosed by the outer bag, a vertical pillow packaging machine is used like the double packaging apparatus currently conventionally disclosed by patent document 1, for example.

JP 2014-108818 Patent 3760266

  In the vertical pillow packaging machine, there is a problem that the number of products manufactured per unit time can not be increased. Therefore, it was considered to perform the packaging process for the drip bag using the horizontal pillow packaging machine capable of coping with the increase of the processing speed in place of the vertical pillow packaging machine.

  In the horizontal pillow packaging machine, the apparatus for transporting and supplying the packaged material is disposed on the upstream side of the bag making apparatus, the packaged product is transported at a constant interval on the apparatus for transporting and supplying packaged material, and the packaged material is sequentially packaged. It is configured to be supplied inside and wrapped by a packaging film supplied separately to a bag making machine. When packaging a drip bag, the said drip bag turns into a to-be-packaged thing, and a finger conveyor apparatus and a belt conveyor apparatus are used for a to-be-packaged article conveyance supply apparatus.

  For example, when the belt conveyor apparatus is used, the following problems occur. That is, the drip bag is a non-woven bag and is slippery. Therefore, if the transport speed is increased to increase the number of products produced per unit time, the drip bag moves relatively back and forth on the belt conveyor, and the relative travel distance can not be ignored as the transport distance increases. As a result, there is a risk that the package film can not be supplied to a desired position without the packaging film, and biting may occur in the subsequent top seal device.

  On the other hand, when the finger conveyor device is used, the transport pitch of the drip bag is the back and forth finger pitch, and the drip bag is supplied to the bag making machine at regular intervals. However, as a form of drip bag, there is a type in which a cardboard hook is attached as a supporting member to the side surface of a non-woven bag as disclosed in, for example, Patent Document 2, and a perforation for opening is formed. When the upper side of the packaging body is conveyed toward the upstream side, when pressed by the finger, the bag body is bent at a perforation, causing positional deviation with respect to the packaging film, and thus causing the biting at the time of sealing in the packaging machine body Become.

  In order to solve the problems described above, the horizontal pillow packaging machine of the present invention comprises: (1) a packaging machine main body having a conveying surface in the horizontal direction, and a film supply device for supplying a packaging film to the packaging machine main body; It is a horizontal pillow packaging machine provided with a package conveying and feeding device for feeding a package to the packing machine main body, and the package conveying and feeding device is a belt conveyor device for conveying the package. An alignment device disposed above the belt conveyor device, wherein the alignment device moves 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 the moving mechanism for moving the blade member, and the moving speed of the blade member is set to be slower than the transfer 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. The movement mechanism corresponds to the endless chain 45 or the like stretched around the sprocket 44 in the embodiment.

  In order to convey the package by the belt conveyor device, even if the package is likely to be depressed or deformed when the package is pushed from the periphery, it can be transported without deformation or the like. And since the conveyance speed of the belt conveyor device is faster than the moving speed of the blade members, it catches up with the blade members and the front end of the package contacts the blade members located forward. When in contact with the blade members, the transport speed of the package is the moving velocity of the blade members. When the blade member reaches the reference position, the blade member separates from the transport surface and accordingly also separates from the package. After the reference position, the transport speed of the package is attributable to the transport speed of the belt conveyor device. Thus, the blade members are separated at the reference position, and the package is positioned at the reference position at the reference position. The objects thus positioned are conveyed from the reference position by the belt conveyor device and sequentially supplied to the next-stage packaging machine body at a predetermined timing. Since the material to be packaged is positioned at the reference position on the belt conveyor device, it is supplied without positional deviation with respect to the packaging machine main body and hence to the packaging film, and the occurrence of bite and the like occurs in the packaging processing in the packaging machine main body. Can be prevented. In particular, when the reference position is set in the vicinity of the delivery side of the belt conveyor device, and the distance from the reference position to the delivery position of the packaging machine main body is shortened, the effect can be further improved. In addition, although the package object moving the belt conveyor device receives an external force when its tip contacts the front blade member, the force is the moving speed of the blade member and the conveyance speed of the belt conveyor device. Based on the difference in speed between them, which is smaller than, for example, when pushing the package from the back with a pushing finger or the like, and the package is not crushed at the time of the contact, or even slight if any. Amount. Therefore, the package is transported without deformation or the like.

  (2) A first stopper member protruding rearward is provided below the rear surface in the moving direction of the blade member, and the upper surface of the tip of the packaged object in contact with the blade member is the first stopper member. It is preferable to be in a state of being in contact with the lower surface, and to be able to prevent the tip of the package from being lifted upward more than that. The first stopper member corresponds to the stopper member 53 in the embodiment. In this case, for example, when the package conveyed by the belt conveyor device comes in contact with the front blade member, it vigorously collides or receives the conveyance force from the belt conveyor device after the contact. Even if the front end of the package is moved along the blade member, the movement of the front end of the package can be suppressed by the first stopper member, so that the package can be accurately positioned.

  (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 protruding below the belt surface may be provided in the portion. According to this configuration, blade members exist above and below the belt surface in the portion where the protrusion is provided. Therefore, it is preferable that the package can be surely positioned by contacting the portion where the blade members exist above and below the belt surface. The present invention relates to the present invention even if the shape of the package is thin, for example, flat, and there is a gap between the belt surface and the lower end of the blade member and there is a risk of entering the gap. It is possible to prevent entry into the gap and perform positioning.

  (4) A finger conveyor device is provided on the upstream side of the belt conveyor device, and the package is transported by a pushing finger of the finger conveyor device in contact with the rear surface so as to be delivered onto the belt conveyor device. It is good to do.

  (5) The article to be packaged is a drip bag, and it is preferable to convey the perforation for opening formed in the bag body of the drip bag in a posture directed to the upstream side. In this case, since the bottom side of the bag is filled with the contents firmly and the bag is relatively hard to be deformed, the wing member can prevent deformation of the package more reliably and positioning can be performed.

  (6) On the surface of the bag body, a support member for supporting the drip bag on the cup when the drip bag is used is attached, and in the backward direction below the rear surface in the moving direction of the wing member A second stopper member may be provided so as to project toward the second stopper member, and in a state where the support member is in contact with the second stopper member, the packaged object may be prevented from further approaching the blade 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, they may be realized by one stopper member 53 as shown in the embodiment, or formed by separate members It is good. When the second stopper member is provided as in the present invention, when the support member comes in contact with the second stopper member, the package does not approach the blade member any more, and thus positioning can be performed.

  According to the present invention, even if the packaged product is an unstable product which is easily deformed due to an external biasing force, for example, it can be supplied to the package film at an accurate position with respect to the packaging film. It is possible to prevent biting of the product.

  Hereinafter, preferred embodiments of the present invention will be described in detail based on the drawings. The present invention is not limited to or interpreted as such, and various changes, modifications, and improvements can be added 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 packaging machine 10 of the present embodiment includes a packaging machine main body 11 and a film supply device 12 for continuously feeding a strip-like packaging film to the packaging machine main body 11; The apparatus is provided with an article transport and supply device 14 disposed upstream of the packaging machine main body 11 and supplying the article 1 to the packaging machine main body 11 at predetermined intervals.

  In the present embodiment, the package 1 is a coffee drip bag, and includes a hook-type support member. That is, as shown to Fig.2 (a), the to-be-packaged item 1 is equipped with the bag body 3 with which the powder | flour 2 of coffee was filled with the inside, and the hook member 4 attached to the side of the bag body 3. The bag 3 is made of non-woven fabric and filled with coffee powder 2 in a state where one side (the upper part in use, the left side in FIG. 2) is opened. The seal portion 3a is formed and sealed. Furthermore, the perforation 5 for opening is formed in the unsealed part along the said sealing part 3a. Moreover, when filling the powder | flour 2 of coffee in the bag 3, it supplies in the bag 3 from the said opening site | part in the state which made the opening side one side. Therefore, coffee powder 2 is relatively densely filled in the posture at the time of supply, that is, the bottom 3 b side of the bag 3 in use. As a result, as shown in FIG. 2B, the bottom 3b side is relatively thick, has a certain degree of hardness, and is relatively unlikely to be crushed. On the other hand, the thickness on the side of the perforation 5 of the bag body 3 becomes thin and the coffee powder 2 also exists in a relatively sparse state, and is crushed and deformed relatively easily when a biasing force is applied from the outside. At the time of use, the bag body is opened by cutting the perforation 5 prior to dripping, and is set in a cup using the hook member 4. As described above, the package 1 has a flat shape in which the plane is rectangular in its entire shape.

  The to-be-packaged thing 1 which concerns is sealed-stored in the flat outer bag 6 as shown to FIG. 2C, and the package body 28 is manufactured. The outer bag 6 is formed of a packaging film such as an aluminum vapor deposition film, one side of the rectangular shape is folded, and the remaining three sides are sealed (side seal portion 6a, top seal portion 6b) for sealing. Further, in the present embodiment, there is not much difference between the cut dimension 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. As a result, there is no room for dimensions in the front-rear direction and the transport direction at the time of wrapping paper processing.

  The film supply device 12 links the output of a drive motor (a motor capable of controlling the speed such as a servomotor) (not shown) to the original fabric roll 16 in which a strip-shaped film 15 such as an aluminum vapor deposition film is wound in a roll. It supplies to the packaging machine main body 11 at a fixed speed, controlling the rotational speed of the film roll 16 suitably. Further, various rollers 17 are disposed at predetermined positions from the original fabric roll 16 to the packaging machine main body 11, and the belt-like film 15 delivered from the original fabric roll 16 is stretched around the roller 17 to provide a predetermined path. Are guided to the packaging machine main body 11. In the present invention, it is not necessary to link the drive motor to the original fabric roll 16 necessarily, 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 package conveying and feeding apparatus 14 conveys the above-mentioned packaged products 1 in a state in which the above-mentioned packaged products 1 are arranged in two horizontal rows, and the two packaged products 1 arranged side by side At the same time, the sheet is supplied to the packaging machine body 11 of the next stage.

  The packaging machine main body 11 is equipped with the bag making device 20 which sets up the strip | belt-shaped film 15 supplied to the upstream side cylindrically. By passing the bag-making apparatus 20, the belt-like film 15 is lifted so that both side ends are curved upward along the bag-making apparatus, and the bag-like film 15 is made into a bag. At this time, the side edges 15a of the belt-like film 15 are respectively positioned on the upper center side and set so as to be close to each other without contact (see FIG. 4). That is, in the case of an ordinary pillow packaging machine, the side edges of the strip-shaped film 15 formed into a tubular shape overlap sealable surfaces with each other, but in the present embodiment, the side edges 15a are cylindrical It opposes to the center part of the strip-shaped film 15 made into a bag shape. Moreover, the to-be-packaged material conveyance supply apparatus 14 supplies the to-be-packaged goods 1 conveyed in 2 rows to the bag making machine 20 one by one. As a result, the folded back side ends of the strip film 15 each cover the upper side of each package 1.

  The conveyance path 22 which comprises the conveyance surface of the cylindrical film 21 which includes the to-be-packaged goods 1 at the downstream of the bag making apparatus 20 is arrange | positioned. The pinch roller 23, the side seal device 24, and the vertical cutter device 25 are disposed at an appropriate position in the center of the transport path 22 from the upstream side. The pinch roller 23 is composed of a pair of upper and lower rollers, and sandwiches the both side edges 15a of the tubular film 15 formed into a tubular shape and the central portion of the ribbon film 15 opposed thereto with a predetermined pressure from above and below A conveying force is applied to the formed band-shaped film 15.

  The side seal device 24 is located on the upper side of the strip-shaped film 15 formed into a tubular shape, and the lower side of the single large disk-shaped side sealer 24 a and the strip-shaped film 15 formed into a tubular shape. , And consists of two small diameter disk-like holding rollers 24b (disposed in front and back). With the side sealer 24a and the pressing roller 24b arranged at the top and bottom, the central edge portion of the both side edges 15a of the strip-shaped film 15 made into a tubular bag and the strip-shaped film 15 opposed thereto are sandwiched from above and below with a predetermined pressure. And heat at a predetermined temperature. Thus, the side edges 15a are heat-sealed to the opposing film portions, and the sealed portions become the side seal portions 6a. Further, by sealing the both side edges 15a with the side seal portion 6a, two cylindrical films 21 connected to the left and right are formed from the band-like film 15 which is bag-shaped in one large cylindrical shape. become. And the to-be-packaged thing 1 is included in these two cylindrical films 21, respectively.

  The vertical cutter device 25 cuts the central portion of the side seal portion 6a, that is, between the two cylindrical films 21 connected to the left and right, and a slit cutter 25a located on the upper side of the cylindrical film 21; It comprises the receiving blade 25b located on the lower side of the cylindrical film 21. 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 which are arranged vertically. Thereby, the side seal part 6a is cut along the advancing direction of a film, and the cylindrical film 21 on either side is isolate | separated.

  On the downstream side of the vertical cutter device 25, a belt conveyor 26 for supporting and conveying the two separated cylindrical films 21 and an article holding belt device 30 are disposed above the belt conveyor 26, and further, A top seal device 27 and a carry-out conveyor 29 are disposed downstream of them.

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

  The material holding belt device 30 is disposed immediately upstream of the top seal device 27. The material holding belt device 30 in the tubular film 21 is prevented from being lifted upward, and is conveyed while maintaining the horizontal state. I am able to do it. The article holding belt device 30 has a configuration in which an endless belt 62 is stretched around pulleys 61 disposed in the front and back.

  The package conveying and feeding device 14 for feeding the two packages 1 at a desired timing with respect to the packaging machine main body 11 includes a finger conveyor device 31 and a belt conveyor device disposed downstream 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 disposed at predetermined positions in the front and rear direction, an endless chain 35 wound around the plurality of sprockets 34, and pushing fingers 36 attached to the endless chain 35 at regular intervals. . The transport path 38 is disposed above the endless chain 35, and the tip end side of the pushing finger 36 advances forward along the transport path 38 as the endless chain 35 rotates in a state of projecting above the transport path 38. . Moreover, the to-be-packaged goods 1 are each supplied on the conveyance path 38 between the pushing feed fingers 36 of back and front by the to-be-packaged material supply apparatus which is not shown in figure. At this time, the package 1 is set on the transport path 38 with the perforations 5 directed upstream.

  Thereby, as shown in FIG. 5, the package 1 placed on the transport path 38 is provided with the seal portion 3a which is the peripheral edge on the perforation 5 side on the pushing finger 36 located on the rear side in the transport direction. As the pushing finger 36 is moved forward, the package 1 is also pushed forward, and is moved forward in two rows with the bottom 3b of the bag 3 facing the downstream side.

  Further, as shown in an enlarged manner in FIG. 6, the downstream end of the transport path 38 is located near the upstream end of the belt conveyor device 32 of the next stage. As a result, when the package 1 pushed by the pushing finger 36 reaches the downstream carry-out end of the finger conveyor device 31, the tip end side moves to the belt conveyor 32 side so as to be pushed out by the pushing finger 36. The conveying force from the conveyor device 32 side is also received. Then, when the pushing finger 36 reaches the downstream end of the finger conveyor device 31, it gradually descends and separates from the package 1. At the time of separation, the package 1 is transferred to the belt conveyor device 32, and moves forward by receiving the transport force from the belt conveyor device 32.

  The belt conveyor device 32 includes pulleys 40 provided at appropriate positions in the front and rear direction, and an endless belt 41 wound around the pulleys 40. The drip bag, which is the material to be packaged 1, is conveyed with the endless belt 41 rotating, with the perforation 5 for opening being directed upstream. Also, the transport speed of the belt conveyor device 32 is set approximately equal to or slightly higher than the transport speed of the film in the packaging machine main body 11 in the latter stage (the moving speed of the strip film 15 supplied to the bag making machine 20). ing. For example, when the transport speed of the film and the transport speed of the package 1 in the belt conveyor 32 are equalized, the package 1 is transferred from the belt conveyor 32 to the strip-shaped film 15 moving in the bag making machine 20. It is preferable that the process can be smoothly performed without applying stress to the package 1, but in the present embodiment, by making the transport speed in the belt conveyor device 32 slightly faster, the package 1 can be more reliably transferred to the packaging machine main body 11 side. I tried to deliver.

  The alignment device 33 includes sprockets 44 provided at predetermined positions before and after the upper space of the belt conveyor device 32, an endless chain 45 stretched over the sprockets 44, and blade members 46 attached to the endless chain 45 at regular intervals. Equipped with As shown in FIG. 8, the endless chains 45 are respectively disposed on the left and right sides in the transport direction of the package 1 and connect the ends of the base bar 50 so as to extend over the pair of endless chains 45. The base bar 50 is an elongated plate, and connects the blade member 46 to the base bar 50 via the L-shaped plate 51. The blade member 46 has a flat plate shape, and in a section moving along the transport direction of the package 1, the blade member 46 is positioned on a vertical surface and takes a hanging posture.

  The left and right ends of the lower end of the blade member 46 are formed with projecting pieces 46a that project downward, and a shallow bottom recess 46b is formed between the left and right projecting pieces 46a. The width of the recess 46 b is wider than the width of the endless belt 41. Then, in a section where the blade member 46 moves along the endless belt 41, the endless belt 41 enters the recess 46b, and the left and right projecting pieces 46a are lower than the belt surface of the endless belt 41, that is, the conveyance surface of the package 1 Move forward while maintaining the position.

Further, at the central portion of the lower end of the blade member 46, a recessed notch portion 46c is provided upward. The notch 46 c is for avoiding interference with the pushing finger 36 of the finger conveyor device 31. That is, for example, when the pushing finger 36 of the finger conveyor device 31 delivers the package 1 to the belt conveyor device 32,
Even if the wing member 46 overlaps the pushing finger 36 back and forth, the pushing finger 36 is located in the notch 46 c of the wing member 46 so as not to be in contact with it.

  Furthermore, the moving speed of the blade member 46 in the alignment device 33 is slower than the transfer speed of the package 1 in the belt conveyor device 32. Thereby, as shown in FIG. 6, immediately after the packaged product 1 is delivered onto the belt conveyor device 32, it is separated from the front blade member 46 by a predetermined distance, and as the belt conveyor device 32 is transported When the distance to the front blade member 46 approaches and reaches near the delivery side of the belt conveyor device 32, the front end (the bottom 3b side of the bag 3 of the drip bag in the transport direction) of the packaged object 1 is the front blade member 46. Contact In the state of being in contact with the blade member 46, the package 1 is transported at the moving speed of the blade member 46.

  As shown in FIG. 7, when the wing member 46 moves upward and separates from the package 1, the package 1 moves at the transport speed of the belt conveyor device 32, and the packaging machine main body 11 (bag making machine 20) Supplied to Since the blade member 46 ascends and separates from the package 1 as the endless chain 45 rotates, the position (reference position) at which the blade member 46 separates from the package 1 is determined. The positional relationship is also uniquely determined. Therefore, the package 1 at the position where the wing members 46 are separated, for example, the distance to the bag making device 20 is constant, and it moves from the position at the transfer speed of the belt conveyor device 32 and reaches the bag making device 20, The film is supplied in a band film 15. This is the same for the packages 1 sequentially transported forward and backward.

  Therefore, once the package 1 is in contact with the wing member 46, the package 1 is aligned on the front basis and supplied to the packaging machine main body 11 at the same timing after being aligned. Therefore, by adjusting the operation timing of the top seal device 27 in the packaging machine main body 11, the position of the belt-like film 15 supplied to the packaging machine main body 11, etc. to the position and timing that the wing member 46 separates from the package 1 Thus, the package 28 can be manufactured without the package 1 being misaligned or the like and without the package 1 being caught.

  In particular, in the present embodiment, since the bottom 3 b side of the bag 3 filled with coffee powder 2 and having a stable shape is brought into contact with the wing member 46, when the package 1 contacts the wing member 46. It is hard to deform the package 1 and it is hard to occur position shift by the modification.

  Furthermore, in the present embodiment, the protrusion 46a is positioned below the belt surface of the endless belt 41, whereby the package 1 can be reliably brought into contact with the blade member 46 and positioned. That is, the width in the transport direction of the package 1 is made wider than the belt width of the endless belt 41. Even if a gap is generated between the recess 46 b and the endless belt 41, the package 1 contacts at least the left and right end portions of the blade member 46 and is positioned.

  Furthermore, in the present embodiment, the time during which the package 1 is in contact with the blade member 46 is shortened, positioning is performed instantaneously, and the conveyance by the belt conveyor device 32 is returned. In order to do this, the transport speed of the belt conveyor device 32 and the speed difference of the moving speed of the blade members 46 are appropriately adjusted, and the belt conveyor device 32 is transported immediately before the blade members 46 separate. Package 1 catches the blade member 46 so that the tip is in contact.

  Furthermore, in the present embodiment, the drive motor of the belt conveyor device 32 is provided separately from the alignment motor 33 and the drive motor on the packaging machine main body 11 side, and operates based on an independent drive source. This is because, as described above, fine adjustment is required for adjusting the speed difference, and mechanical adjustment such as gear ratio becomes complicated, so it is easy to make an optimal setting using another drive motor. There is.

  Furthermore, the position at which the blade member 46 separates from the package 1 is close to the bag making device 20, that is, near the delivery side of the belt conveyor device 32, and soon after separation, the package 1 forms the bag It is good to be supplied in 20.

  Although the conveyance speed by the belt conveyor device 32 is made faster than the movement speed of the blade members 46, preferably, the speed difference is small. By reducing the speed difference, it is possible to reduce the stress applied to the package 1 when the package 1 contacts the blade member 46. However, if the speed difference is small, the moving distance of the belt conveyor device 32 needs to be increased, which causes the apparatus to be large, and the speed difference is appropriately set in consideration of that.

  Furthermore, in the present 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 the lower end of the stopper member 53 protrudes rearward. And the lower surface of the projected portion becomes the first locking surface 53a, and the rear surface becomes the second locking surface 53b.

  The first locking surface 53 a forms a fixed gap with the endless belt belt surface of the belt conveyor device 32, and in the state where the tip of the packaged object 1 is in contact with the blade member 46, The tip end, that is, the bottom 3b of the bag 3 is located in the gap. As a result, when the bottom 3b of the bag 3 is intended to be lifted upward, the bottom 3b contacts the first locking surface 53a to prevent the lifting.

  The second locking surface 53b allows contact with the hook member 4 of the package 1 moved forward. That is, for example, the conveying force from the belt conveyor device 32 is large, and the tip of the article 1 is moved forward relative to the wing member 46 even after the tip of the article 1 contacts the wing member 46, and the tip of the article 1 is crushed In this case, the hook member 4 contacts the second locking surface 53b to inhibit further relative forward movement. Thereby, it is suppressed as much as possible that the bottom part 3b side of the bag 3 collapses.

  In the embodiment described above, the package 1 is transported with the bottom 3b side of the bag body 3 on the front side, but the transport posture of the package 1 is reversed back and forth and the side on which the perforations 5 are formed is the transport You may do it.

  In the embodiment described above, the package is a drip bag of coffee, the hook member 4 is attached to the side surface of the bag 3, and the hook member 4 is not positioned at the periphery of the bag 3 in the transport state. In the existing type, when the peripheral edge is pushed inward, the pressed portion is likely to be dented or deformed, but the present invention is not limited to this, and the package is a drip bag of other types. It may be an item other than the drip bag. However, when it is pushed from the back, it works effectively for those with a structure that is easily deformed.

  While the various aspects of the invention have been described above using embodiments and variants, these embodiments and descriptions have not been made for the purpose of limiting the scope of the invention, but rather to understand the invention. It should be added that it was provided to help. The scope of the present invention is not limited to the configurations and processes explicitly described in the specification, and includes within its scope combinations of various aspects of the present invention disclosed herein.
