Abstract
Description
Technical Field
[0001] This application relates to an apparatus and method for mounting a strip-shaped component on the main body of a bag, such as a plastic or paper bag. Background Technology
[0002] Regarding bags made primarily of materials such as plastic or paper, the contents can include all types of items, such as snacks, powders, granules, and liquids. Furthermore, the demand for resealable bags is increasing, with resealable zipper straps being a common method of resealing.
[0003] As a bag-making method for bags with strip-shaped components such as zipper straps, there is a method in which the strip-shaped component is installed on the main body material while bag making is being carried out. However, this method requires a strip-shaped component installation device in the bag-making machine, and the bag-making machine tends to become larger and more complex.
[0004] On the other hand, there is also a bag-making method in which the strip-shaped component is pre-installed on the main body material and the main body material is wound into a roll. In this method, since the strip-shaped component is pre-installed on the main body material, there is no need for a strip-shaped component installation device in the bag-making machine, and bags with zipper straps can be manufactured using a conventional bag-making machine with a simple structure.
[0005] Furthermore, in bag-making methods that use a main body material pre-installed with a strip-shaped component such as a zipper tape, additional processing of the strip-shaped component is sometimes required. This additional processing includes sealing a protective strip, which serves as a protective component, within the strip-shaped component installed on the main body material.
[0006] As shown in Patent Document 1, the protective strip is sealed onto the main body material by covering the strip material from above.
[0007] However, Patent Document 1 does not specify how the protective strip is cut, or from what type of base material it is supplied to the main body material for sealing. Typically, when cutting the protective strip to a specified size, a certain degree of tension is required from both the upstream and downstream sides. Therefore, it is suitable to use a Thomson blade to punch holes in the protective strip, but this will generate punching waste (excess material loss).

[0055] Hereinafter, embodiments of the strip member installation device and strip member installation method of the present invention will be described with reference to the accompanying drawings.
[0056] <First Implementation>
[0057] [Bag 1 with zipper strap]
[0058] based on Figures 1-6 The following describes a bag 1 (hereinafter, sometimes simply referred to as a "bag") with a zipper strap 2. Furthermore, the width direction X, the long side direction Y, and the thickness direction Z of the bag 1 are orthogonal to each other.
[0059] like Figure 1 As shown, bag 1 includes a first main body 11 and a second main body 12 that are rectangular in shape and face each other in the thickness direction Z. Figure 2 and Figure 4 The main body material 11 and main body material 12 comprise a plastic film. In this embodiment, the main body material 11 and main body material 12 are constructed from a single plastic film, which is folded and adhered to the inside (so-called folding and pasting). In this embodiment, the main body material 11 is the outer main body material, and the main body material 12 is the inner main body material having a back sealing portion (not shown). Furthermore, the main body material 11 may be constructed from a single film, and the main body material 12 may be constructed from another film.
[0060] The main body material 11 and main body material 12 include a bottom sealing portion 13 and a top sealing portion 14 parallel to the width direction X. The sealing portions 13 and 14 are formed by heat sealing the upper and lower parts of the main body material 11 and main body material 12 together. Alternatively, the main body material 11 and main body material 12 can also be constructed by overlapping a sealant on a substrate containing paper raw materials.
[0061] Furthermore, the bag 1 includes a zipper tape 2 and a cutting tape 3 extending in the width direction X on the top sealing portion 14 side. In this embodiment, the zipper tape 2 and the cutting tape 3 are integrally formed.
[0062] like Figure 2 As shown, the zipper tape 2 is disposed between the main body 11 and the main body 12. The zipper tape 2 includes a male fastener 21 and a female fastener 22. The male fastener 21 and the female fastener 22 extend in the width direction X.
[0063] The male fastener 21 includes a mounting base 21A and a protrusion 21B. The female fastener 22 includes a mounting base 22A and a recess 22B. The protrusion 21B and the recess 22B face each other in the thickness direction Z. The protrusion 21B and the recess 22B are made of a resiliently deformable material such as synthetic resin, and are configured to engage and disengage.
[0064] The mounting base 21A of the male fastener 21 is heat-sealed (heat-fused) to the body material 11. The end 221A of the mounting base 22A of the female fastener 22 is heat-sealed to the body material 11 between the top sealing part 14 and the mounting base 21A of the male fastener 21.
[0065] The cutting strip 3 is positioned between the mounting base 21A of the male fastener 21 and the end 221A of the mounting base 22A of the female fastener 22. The positional relationship between the male fastener 21 and the female fastener 22 can also be reversed.
[0066] like Figure 1 As shown, bag 1 includes a pull tab 4 on one side in the width direction X. The pull tab 4 is positioned to overlap with the cutting strip 3. The pull tab 4 is formed through a first punched portion 41. Additionally, bag 1 includes a second punched portion 43 on the other side in the width direction X.
[0067] like Figure 1 and Figure 2 As shown, the first punched portion 41 and the second punched portion 43 are formed by punching holes in the main body 11, the cutting strip 3, the mounting base 21A of the male fastener 21, and the mounting base 22A of the female fastener 22.
[0068] The first punched portion 41 is a cutout that is approximately "C" shaped when viewed from above, with a cutting strip 3 disposed at the "C"-shaped opening. A portion of the cutout is formed at the location where the main body 11 and the cutting strip 3 overlap in the thickness direction Z.
[0069] The second punched portion 43 is a straight-line cut extending in the long side direction Y (a direction perpendicular to the peeling direction of the pull tab 4). A portion of the cut is formed at the location where the main body 11 and the cutting strip 3 overlap in the thickness direction Z, and extends across the entire width of the cutting strip 3.
[0070] like Figure 1 and Figure 2 As shown, bag 1 includes a protective strip 5. The protective strip 5 is designed to prevent foreign objects from entering the bag 1 from the outside through the first punch 41 and the second punch 43. Therefore, the protective strip 5 is disposed between the main body material 11 and the main body material 12. Two protective strips 5 are provided, one of which is disposed opposite the first punch 41, and the other is disposed opposite the second punch 43. Figure 3 As shown, the protective strip 5 is then sealed to the body material 11 by surrounding the sealing portion 117b to cover the entire width of the zipper strip 2 surrounding the first punch portion 41 / second punch portion 43.
[0071] [Opening procedure for bag 1 with zipper strap]
[0072] based on Figures 4-6 The opening process of bag 1 with zipper strap is explained.
[0073] like Figure 4 and Figure 5As shown, the user pulls the pull tab 4 up along the thickness direction Z. Since the first punched portion 41 punches into the main body 1, the cutting strip 3, the mounting base 21A of the male fastener 21, and the mounting base 22A of the female fastener 22, the pull tab 4 can be easily lifted up along the thickness direction Z by pressing from one side of the main body 12. The cutting strip 3 is made of a raw material with higher strength than the main body 11. Therefore, when the user pulls the pull tab 4 in the opening direction, the main body 11 is torn by the cutting strip 3 connected to the first punched portion 41.
[0074] like Figure 5 As shown, the user pulls up and yanks the cutting strip 3 and the pull tab 4 together, tearing the main body material 11 located at the position of the cutting strip 3. At the moment the tear reaches the second punched portion 43, which is pre-formed as a straight-line cut by stamping, the main body material 11 and the torn portion of the cutting strip 3 separate from the bag 1, and the bag 1 is opened. Figure 6 As shown, after opening, the bag 1 can be resealed and reopened by engaging and disengaging the male fastener 21 and female fastener 22 of the zipper tape 2. Furthermore, the positional relationship between the male fastener 21 and the female fastener 22 can also be reversed.
[0075] [Strip component installation device 100 and strip component installation method]
[0076] based on Figures 7-12 The installation device and method for installing the strip member 23 on the main body 13 of the bag 1 with zipper strap as the main body 11 and / or main body 12 are described.
[0077] like Figure 7 As shown, in this embodiment, the bag-making machine for manufacturing a bag 1 with a zipper strap, or the main body material manufacturing machine for manufacturing the main body material 11 and 12 of the bag 1 with a zipper strap, includes a strip-shaped component mounting device 100. The bag-making machine or the main body material manufacturing machine includes a conveying device (e.g., including a drive roller) that intermittently conveys the main body material 13 in the form of a web containing a sheet of plastic film or paper along the main body material conveying direction 13X (the length direction 13a of the main body material 13). Therefore, the main body material 13 is repeatedly conveyed and temporarily stopped.
[0078] Then, the bag-making machine continued... Figure 7 In the subsequent step (not shown), the two sides of the main body material 13 in the width direction 13b are folded along the fold lines 13c and 13d in the length direction 13a of the main body material 13. Figure 7 The front side is folded and glued together (so-called folding and gluing) to form the main body material 11 and main body material 12 of bag 1 in the form of a roll. The bag making machine uses the upper surface of the main body material 13 ( Figure 7 The inner surface of bag 1 and the lower surface of main body material 13 are formed by the near front side of the bag. Figure 7The bag 1 is manufactured in such a way that the inner side of the main body 13 forms the outer surface of the bag 1. In addition, the bag making machine includes a cross-cutting device in its downstream section, which cross-cuts the main body 13 along the width direction 13b during each intermittent feed, thereby forming the bag 1.
[0079] The strip component installation device 100 includes a strip component feeder 102. The strip component feeder 102 conveys and supplies an elongated strip component 23, including a zipper tape 2 and a cutting tape 3, to the upper surface of the main body 13 along a strip component supply direction 23X (the length direction 23a of the strip component 23) that is perpendicular to the main body material conveying direction 13X.
[0080] Although not shown, the strip component feeder 102 includes a chuck for clamping the strip component 23, a first actuator for operating the chuck, and a second actuator for moving the chuck. The strip component feeder 102 uses the chuck to clamp the strip component 23, causing the clamped chuck to move along the strip component conveying direction 23X, thereby conveying the strip component 23 to a predetermined position on the upper surface of the body material 13. Since the strip component feeder 102 supplies the strip component 23 to the body material 13 during each intermittent feed, the strip component 23 is supplied to the upper surface of the body material 13 at predetermined intervals (intermittent conveying distance) in the body material conveying direction 13X.
[0081] Additionally, the strip component mounting device 100 includes a strip component easy-tear line processing machine 101. The strip component easy-tear line processing machine 101 forms easy-tear lines across the width direction 23b of the strip component 23 at predetermined intervals along its length direction 23a (strip component conveying direction 23X), using either a piercing punch or ultrasonic waves from an ultrasonic device. Strip components 23 cut to a predetermined length along these easy-tear lines are then positioned between the fold lines 13c and 13d of the main body material 13 via the aforementioned strip component supply machine 102.
[0082] The strip component supply machine 102 uses a chuck to transport the strip component 23 during the transport of the main body 13 or during a temporary stop. Additionally, the strip component mounting device 100 includes a temporary strip component fixing machine 103. After the strip component 23 is transported to a predetermined position on the main body 13 by the strip component supply machine 102, it is temporarily fixed to the main body 13 by the temporary strip component fixing machine 103 when the main body 13 is stopped.
[0083] In this embodiment, the strip component feeder 102 uses a chuck to transport the strip component 23 during the transport of the main body 13. However, if the transport of the strip component 23 begins simultaneously with the transport of the main body 13, the leading edge of the strip component 23 may sometimes collide with another strip component 23 temporarily fixed to the main body 13. Therefore, the transport of the strip component 23 is configured to begin only after the main body 13 has been transported a distance equivalent to the width of the strip component 23, so that the strip component 23 does not collide with the other strip component 23. Then, the transport of the strip component 23 is completed only when the transport of the main body 13 is finished.
[0084] In this embodiment, the chuck of the strip component feeder 102 clamps the front end of the strip component 23 and moves the strip component 23 to a predetermined position. Then, after the strip component temporary fixing machine 103 temporarily fixes the front end of the strip component 23 to the main body 13, the chuck pulls the strip component 23 back upstream, thereby cutting the strip component 23 at the tear line. Other known techniques may also be used for the method of cutting the strip component 23 at the tear line.
[0085] The temporary fastener 103 temporarily fixes the strip member 23 to the main body 13 using known techniques such as heat sealing with a heat-sealing strip or ultrasound with an ultrasonic device. In this embodiment, the temporary fastener 103 temporarily fixes the strip member 23 at its downstream end in the conveying direction 23X, but it can also temporarily fix the strip member 23 at both the upstream and downstream ends in the conveying direction 23X depending on the physical positional relationship based on the configuration of surrounding devices.
[0086] Additionally, the strip member mounting device 100 includes a strip member sealing machine 104 disposed downstream of the strip member temporary fixing machine 103. The strip member sealing machine 104 seals the strip member 23, temporarily fixed by the strip member temporary fixing machine 103, onto the main body 13 by heat sealing, for example, using a heat sealing strip. The strip member sealing machine 104 is configured to utilize a sealing portion 104a extending in the width direction 13b of the main body 13. Figure 2 The mounting base 22A of the sealing female fastener 22 is connected to the main body 13, and a sealing portion 104b extending in the width direction 13b of the main body 13 is used. Figure 2 The mounting base 21A of the sealing male fastener 21 is sealed to the main body 13. At this time, the cutting strip 3, which is integrally assembled with the zipper tape 2, is also sealed to the main body 13. This sealing process is performed during each intermittent feed.
[0087] The sealing area is then cooled by a known cooling method (not shown), thereby ensuring a smooth and high-quality seal free of wrinkles or other imperfections.
[0088] The strip component installation device 100 includes a first press 105 and a second press 106 disposed downstream of the strip component sealing machine 104.
[0089] The first stamping machine 105 is used to provide a first punched portion 41 on the bag 1. Figure 1 The main body 13 and the strip component 23 are stamped. In addition, such as... Figure 2 As shown, the first punched portion 41 is formed on the main body 11, the cutting strip 3, the mounting base 21A of the male fastener 21, and the mounting base 22A of the female fastener 22.
[0090] The second punching machine 106 is used to provide a second punched portion 43 on the bag 1. Figure 1 The main body 13 and the strip component 23 are stamped. In addition, such as... Figure 2 As shown, the second punched portion 43 is formed by punching holes in the main body 11, the cutting strip 3, the mounting base 21A of the male fastener 21, and the mounting base 22A of the female fastener 22.
[0091] The first punching machine 105 and the second punching machine 106, for example, use actuators to move punching blades with blade tips shaped like punched portions 41 and 43, respectively, to punch holes in the main body material 13 and the strip member 23, thereby forming the first punched portion 41 and the second punched portion 43. Furthermore, the positional relationship between the pull tab shape of the first punched portion 41 and the straight line shape of the second punched portion 43 can be reversed, and appropriately selected according to the bag-making conditions. This punching process is performed during each intermittent feed.
[0092] like Figure 1 and Figure 2 As shown, bag 1 includes a pair of protective straps 5. The protective straps 5 are designed to prevent foreign objects from entering the bag 1 from the outside through the first perforation 41 and the second perforation 43. Therefore, each protective strap 5 is disposed between the main body material 11 and the main body material 12, and is joined to the main body material 13 in a manner that completely surrounds the first perforation 41 and the second perforation 43 and covers the entire width of the zipper tape 2. The joining method between the protective straps 5 and the main body material 13 is not limited to heat sealing; any sealing method such as ultrasonic bonding is acceptable.
[0093] like Figure 7 As shown, the strip component mounting device 100 includes raw material 50 for a pair of protective strips 5 disposed downstream of the first press 105 and the second press 106. Figure 8 As shown, a pair of raw materials 50 are positioned above the main body 13, configured to be pulled out along the conveying direction 13X of the main body.
[0094] like Figure 8As shown, the strip component mounting device 100 includes a protective strip feeder 113 on the underside of the raw material 50. The protective strip feeder 113 is configured to feed a continuous protective strip 5 from the raw material 50 for a predetermined length. The protective strip feeder 113 is constructed using known technology, for example, by using a pinch roller to feed the protective strip 5 for a predetermined length, or by conveying a slider holding the protective strip 5 for a predetermined length.
[0095] The strip component mounting device 100 includes a first strip guide 114 on the downstream side of the protective strip feeder 113. The first protective strip guide 114 is composed of a pinch guide roller. The first protective strip guide 114 is configured to guide the protective strip 5 from the raw material 50 and feed it downstream.
[0096] Additionally, the strip member mounting device 100 includes a second protective strip guide 115 downstream of the first protective strip guide 114. The second protective strip guide 115 includes a rectangular through hole for the protective strip 5 to pass through and be guided. The second protective strip guide 115 is configured to move in the width direction 13b of the main body to position the protective strip 5 at a predetermined position on the main body 13.
[0097] Additionally, the strip member mounting device 100 includes a protective strip tear line processing machine 116, a protective strip temporary fixing machine 117, and a protective strip pressing member 121 on the downstream side of the second protective strip guide 115. The protective strip tear line processing machine 116 is positioned a predetermined distance 116a from the protective strip temporary fixing machine 117 upstream of the protective strip 5. To minimize the unwanted portions of the protective strip 5, the predetermined distance 116a should be as small as possible. Furthermore, in this embodiment, the protective strip tear line processing machine 116 and the protective strip temporary fixing machine 117 are modularized, but this is not a limitation; they could also be structures that can be controlled independently.
[0098] The protective belt 5, guided to the designated position by the second protective belt guide 115, is perforated and has easy-tear lines 5b (such as perforation) made on the protective belt 5 by the protective belt easy-tear line processing machine 116 (with its perforation knife 1160) during a single stop of the main body 13. Simultaneously, the protective belt temporary fixing machine 117 (with its heat-sealing strip) sets easy-tear lines 5b on both sides 117a of the strip member 23 in the width direction 23b. Figure 10 A) It is heat-sealed (temporarily fixed) to the main body material 13.
[0099] More specifically, since the protective tape temporary fixing machine 117 and the protective tape easy-tear line processing machine 116 are integrally constructed, the piercing knife 1160 and the heat sealing strip are moved up and down integrally by a common actuator. In order to reliably perform the piercing process, the piercing knife 1160 at the front end of the protective tape easy-tear line processing machine 116 protrudes more than the sealing surface (sealing surface of the heat sealing strip) of the lower surface of the protective tape temporary fixing machine 117.
[0100] like Figure 9 As shown, a protective belt pressing member 121 is provided between the protective belt temporary fixing machines 117. When the protective belt 5 is heat-sealed (temporarily fixed) to the main body 13 by the protective belt temporary fixing machine 117 ( Figure 9 A), at the moment before the perforating knife 1160 at the front end of the protective tape easy-tear line processing machine 116 penetrates the protective tape 5, the protective tape pressing part 121 presses the protective tape 5 onto the main body 13. Figure 9 B).
[0101] The protective belt pressing member 121 can be a cylindrical member that is longer than the width of the protective belt 5, and can be configured to move up and down by a separate actuator independent of the protective belt temporary fixing machine 117. For example, it is sufficient to configure a unit in which the protective belt pressing member 121 is mounted on the front end of the drive arm.
[0102] Subsequently, when the perforating blade 1160 of the protective tape tear-off processing machine 116 protrudes into the protective tape 5, although the temporary protective tape fixing machine 117 (its heat-sealing strip) has not yet come into contact with the protective tape 5, the protective tape pressing member 121 presses the protective tape 5 against the main body 13, therefore the protective tape 5 will not be pulled upstream. Figure 9 C). Then, the temporary fixing machine 117 for the protective belt abuts against the protective belt 5, and the protective belt 5 is fused to the main body 13 ( Figure 9 D).
[0103] like Figure 11 As shown, the protective tape tear line processing machine 116 includes a perforating blade 1160 for forming perforations as tear lines 5b on the protective tape 5. The perforating blade 1160 includes blade tips 1160a arranged in a straight line at predetermined intervals. Each blade tip 1160a is configured to be inclined. In addition, the protective tape tear line processing machine 116 includes an actuator for vertically moving the perforating blade 1160.
[0104] In addition, such as Figure 8 and Figure 11 As shown, a protective tape receiving platform 112 is disposed on the lower side of the piercing blade 1160. The protective tape receiving platform 112 then includes a plurality of holes 1120 spaced apart at predetermined intervals, forming a through-hole. Thus, by inserting each tip 1160a of the piercing blade 1160 into each hole 1120, a perforation can be reliably formed on the protective tape 5. However, the relevant components are designed so that even when the tip 1160a is at bottom dead center, it does not protrude from the lower surface of the protective tape receiving platform 112.
[0105] Multiple holes 1120 can also replace through holes as slots (bottomed holes). Alternatively, the protective tape receiving platform 112 can replace multiple holes 1120 and have a slot (bottomed hole) or elongated hole (through hole) that is slightly wider than the thickness of the piercing tool 1160 for all the tool tips 1160a to enter.
[0106] With this structure, when the protective strip 5 is pressed onto the main body 13 by the protective strip pressing member 121, the piercing knife 1160 of the protective strip tear line processing machine 116 penetrates into the protective strip 5 and is heat-sealed (temporarily fixed) to the main body 13, thus enabling accurate heat sealing without positional deviation.
[0107] like Figure 8 As shown, the strip member mounting device 100 includes a first main member guide 107 and a second main member guide 108 for guiding the main member 13. The first main member guide 107 and the second main member guide 108 are composed of guide rollers. The second main member guide 108 is disposed under the protective strip receiving table 112 to guide the main member 13 to the underside of the protective strip receiving table 112. The first main member guide 107 and the second main member guide 108 guide the main member 13 such that the main member 13 is conveyed relative to the protective strip receiving table 112 to the side opposite to the piercing knife 1160.
[0108] Additionally, the strip component mounting device 100 includes a heater base 119 disposed below the protective strip temporary fixing machine 117. The main body 13 and the protective strip 5 are then overlapped on the heater base 119. Thereby, the protective strip temporary fixing machine 117 uses an actuator to move a heat-sealing strip toward the heater base 119, thereby heat-sealing the protective strip 5 to the main body 13. Simultaneously, the protective strip easy-tear line processing machine 116 can form an easy-tear line only on the protective strip 5 using a piercing knife 1160.
[0109] Since the main body 13 is guided to the upper side of the heater base 119 after being guided to the lower side of the protective belt receiving platform 112, in this embodiment, the portion 119a in which the main body 13 is introduced into the heater base 119 is configured as an arc shape so that the main body 13 will not wear at the contact portion with the heater base 119.
[0110] In addition, such as Figure 8 As shown, during the operation of the protective tape tear-off processing machine 116 and the protective tape temporary fixing machine 117, a protective tape 5 of a specified length is fed out by the protective tape feeder 113. However, due to the one-time stop of the main body 13, a deflection 5a of the protective tape 5 occurs between the first protective tape guide 114 and the second protective tape guide 115.
[0111] When the operation of the protective tape tear-off processing machine 116 and the protective tape temporary fixing machine 117 ends ( Figure 12 A) The transport of the main body 13 begins. Through the transport of the main body 13, the protective belt 5, heat-sealed onto the main body 13 by the temporary fixing machine 117, is transported integrally with the main body 13. Figure 12 B). When the protective belt 5 is conveyed integrally with the main body 13, the tear line 5b formed on the protective belt 5 is positioned downstream of the protective belt temporary fixing machine 117, and the deflection 5a of the protective belt 5 is eliminated. Figure 12 B). Furthermore, when the protective belt 5 is conveyed integrally with the main body 13, a pulling force is generated on the protective belt 5, and the protective belt 5 is torn at the tear line 5b. The front end 5b of the protective belt 5 is positioned slightly downstream of the protective belt temporary fixing machine 117. Figure 12 C).
[0112] Then, the conveying of the main body 13 stops, the operation of the protective tape tear-off processing machine 116 and the protective tape temporary fixing machine 117 begins, and the protective tape 5 of the specified length is sent out. Figure 12 A) When the protective tape tear-off processing machine 116 and the protective tape temporary fixing machine 117 finish their operation, the conveying of the main body 13 begins. Figure 12 B), the protective tape 5 was torn at the tear line 5b ( Figure 12 C), and so on, repeating the cycle.
[0113] In addition, such as Figure 7 As shown, the strip member installation device 100 includes a protective belt sealing machine 118 disposed downstream of the protective belt temporary fixing machine 117. The protective belt 5 passes through the protective belt temporary fixing machine 117 on both sides of the strip member 23 in the width direction 23b. Figure 10 A) After being heat-sealed to the main body 13 to form a sealing part 117a, it is then sandwiched together with the main body 13 into the strip member 23 (zipper tape 2) by a protective tape sealing machine 118 in a manner that surrounds the first punched portion 41 and the second punched portion 43 on both sides of the strip member 23 and is heat-sealed, thereby forming a sealing part 117b. Figure 10 B. Figure 3 ).
[0114] The heat sealing performed by the protective tape sealing machine 118 ensures a tight seal relative to the punched portions 41 and 43. However, since the sealing strength of the protective tape 5 between the cutting tape 3 and the mounting base 22A of the female fastener 22 is weak, it does not hinder the opening of the seal performed by the cutting tape 3.
[0115] More specifically, in the thickness direction Z, the mounting base 22A and the protective strip 5 are heat-sealed. Although the mounting base 22A and the cutting strip 3 are in close contact, they are not completely heat-sealed. Therefore, as... Figure 3 As shown, when the first punched part 41 (pull tab 4) is erected in the Z direction and opened across the heat-sealed part 117b in the X direction, it will not hinder the opening of the cutting strip 3.
[0116] Therefore, through the stamping process of the first stamping machine 105 and the second stamping machine 106, even if the punched portions 41 and 43 penetrate from the main body 13 (main body 11) to the mounting base 22A of the female fastener 22, the airtightness of the bag 1 can be ensured by covering the penetrating punched portions 41 and 43 with the protective strip 5 and heat-sealing the area around the punched portions 41 and 43.
[0117] As described above, a protective strip 5 of a specified length is fed from the raw material 50 disposed on the upper side of the main body material 13 along the main body material conveying direction 13X. The protective strip 5 of the specified length is conveyed in conjunction with the conveying of the main body material 13, and an easy-tear line 5b is processed on the protective strip 5. Thus, in conjunction with the conveying of the main body material 13, the front end 5b of the protective strip 5 in the next processing is conveyed to a specified position, thereby preventing excess material loss during bag making.
[0118] <Second Implementation>
[0119] based on Figure 13 and Figure 14 The second embodiment of the bag 1 with a zipper strap will be described. Furthermore, structures identical to those in the first embodiment will be omitted to avoid repetition.
[0120] like Figure 13 As shown, the cutting strip 3 is completely fused with and heat-sealed to the mounting base 22A of the female fastener 22. However, due to the material difference between them, although they are tightly bonded, they are in a state where they can be easily peeled off.
[0121] like Figure 14 As shown, when the user stands the pull tab 4 upright along the Z direction and pulls it in the opening direction, although the pull tab 4 is integrally stacked from the main body 11 to the mounting base 22A of the female fastener 22, the mounting base 22A of the female fastener 22 is torn off at the sealing edge of the protective strip 5, which will be described later, so that it can be opened smoothly afterwards.
[0122] The first punched portion 41 serves as the handle (pull tab 4) at the start of opening. When opening the package, the user lifts the pull tab 4, which is integrally formed from the main body 11 and the strip member 23, and pulls it in the opening direction. At this time, when the pull tab 4 reaches the inner edge of the rectangular sealing portion of the protective strip 5 after being sealed by the protective strip sealing portion 118, the mounting base 22A of the female fastener 22 breaks at the inner edge of the rectangular sealing portion of the protective strip 5 due to the so-called edge breakage phenomenon. Subsequently, the main body 11 and the cutting strip 3 are torn while overlapping, and the torn portion separates from the bag 1 at the point when it reaches the second punched portion 43, which is a straight-line cut.
[0123] Furthermore, the positional relationship between the male fastener 21 and the female fastener 22 can also be reversed. Additionally, the positional relationship of the cutting strip 3 is not limited to a continuous arrangement at the mounting base 21A of the male fastener 21, such as... Figure 13 As shown, it can also be configured on one side of the mounting base 22A of the female fastener 22.
[0124] The embodiments described above are not limited to these embodiments. For example, the following modifications may also be made.
[0125] The temporary fixing machine 103 for strip components, the sealing machine 104 for strip components, the temporary fixing machine 117 for protective belts, and the sealing machine 118 for protective belts can also be heat-sealed without the use of heat sealing strips. For example, the strip component 23 and the protective belt 5 can be sealed together by applying adhesives such as those from an applicator or by using a spacer adhesive.
[0126] The strip member mounting device 100 may also include a sensor downstream of the protective strip temporary fixing machine 117 to detect the position of the front end 5b of the protective strip 5. This sensor allows for highly precise positioning of the front end 5b of the protective strip 5.
[0127] Therefore, when the front end 5b of the protective belt 5 is located upstream of the predetermined position (designed position), a signal is sent to the protective seal feeder 113 to increase the feed amount of the protective belt 5 in the next processing step, thereby positioning the front end 5b of the protective belt 5 in the predetermined position for the next processing step. Conversely, when the front end 5b of the protective belt 5 is located downstream of the predetermined position, a decrease in the feed amount of the protective belt 5 in the next processing step can also position the front end 5b of the protective belt 5 in the predetermined position for the next processing step. For example, the protective belt feeder 113 includes a processor configured to control the rotation amount of the pinch rollers or the movement amount of the slider based on the signals from the sensors.
[0128] The strip member installation apparatus 100 according to the embodiments of this application includes: a strip member supply machine 102, which intermittently feeds a main body 13 along a main body feeding direction 13X, and supplies strip members 23 along a strip member feeding direction 23X perpendicular to the main body feeding direction 13X; a strip member sealing machine 104, which seals the strip members 23 on the main body 13; and a stamping machine 105 and a stamping machine 106, which form punched portions 41 on the main body 13 and the strip members 23. The system includes: a punched section 43; a protective tape feeder 113 that feeds a protective tape 5 of a specified length to the main body 13 and the strip member 23 along the main body conveying direction 13X; a protective tape guide 115 that guides the protective tape 5 so that the punched sections 41 and 43 are covered by the protective tape 5; a protective tape easy-tear line processing machine 116 that forms easy-tear lines on the protective tape 5 at specified intervals; and a protective tape sealing machine 118 that seals the protective tape 5 on the main body 13 and the strip member 23.
[0129] The strip member installation device 100 seals a protective strip 5 of a predetermined length on the main body 13 and the strip member 23, and after forming an easy-tear line 5b on the protective strip 5, it transports the main body 13, thereby enabling the protective strip 5 of the predetermined length to be cut at the easy-tear line 5b, and enabling the protective strip 5 of the predetermined length to be sealed on the main body 13 and the strip member 23. Therefore, the protective strip 5 can be installed on the strip member 23 without excess material loss.
[0130] Preferably, the protective tape tear line processing machine 116 includes a perforating knife 1160 for forming tear lines 5b, and the strip member mounting device 100 includes a protective tape receiving platform 112 for receiving the perforating knife 1160, and a main body guide 107 and a main body guide 108, which guide the main body 13 so that the main body 13 is conveyed relative to the protective tape receiving platform 112 to the side opposite to the perforating knife 1160.
[0131] Therefore, the protective tape tear line processing machine 116 is able to form tear lines 5b only on the protective tape 5.
[0132] Alternatively, ideally, the protective strip receiving platform 112 includes multiple holes 1120 for the tips 1160a of the perforating blade 1160 to enter. Furthermore, the holes 1120 can be through holes or bottomed holes.
[0133] Therefore, by inserting the tips 1160a of the perforating tool 1160 into the holes 1120, perforations can be reliably formed on the protective strip 5. (Explanation of reference numerals in the attached drawings)
