  2. Description of the Related Art Conventionally, products in which a plurality of articles filled with snack confectionery or the like are pasted on a strip or the like are known. This product is displayed in a suspended state in which a part of the mount is locked at a retail store or the like, and the purchaser peels off the individual articles from the mount. ). This strip pack is advantageous in that it saves display space and diversifies its design, and promotes the willingness to purchase.

  As a strip pack apparatus for manufacturing such a strip pack, for example, an apparatus described in Patent Document 1 is placed immediately below a vertical bag making and packaging machine, and a pair of left and right upper parts of an article manufactured by the packaging machine are placed on the left and right sides. The upper arm of the article is attached to the mount after the article is moved to the lower application position by being held by the holding arm. The apparatus described in Patent Document 2 is also placed directly under the vertical bag making and packaging machine, and the upper one surface of the article manufactured by the packaging machine is sucked with a suction cup and the article is moved to the front sticking position. Then, the upper end of the article is attached to the mount.

JP 2004-182302 A (paragraph 0034, FIG. 4, FIG. 6, FIG. 10) U.S. Pat. No. 3,864,895 (FIG. 1, text, second column, lines 31-62)

  By the way, since the strip pack apparatus of patent document 1 and 2 is directly connected with the vertical bag-making packaging machine arrange | positioned directly on it, only the articles manufactured with this packaging machine can be made into a strip pack. . In addition, quality inspections such as weight and sealability cannot be performed before an article manufactured by the packaging machine is made into a strip pack. Therefore, it is desired to propose a highly versatile strip pack device having a configuration independent of the upstream device and the downstream device. In this case, the basic configuration of the strip pack apparatus includes a conveying means for conveying an article in a substantially horizontal direction, a moving means for moving the article conveyed by the conveying means to a sticking position, and the moving means moved by the moving means. A sticking means for sticking the article to the mount is provided.

  In that case, it becomes a problem where the sticking position is arranged with respect to the conveying means. If the sticking position is arranged above the conveying means, the moving means must raise the article, which is not common. If the sticking position is arranged on the side of the conveying means, the article moves laterally, the width of the strip pack device is increased, and the layout is deteriorated. In that respect, if the sticking position is disposed below the conveying means, the moving means may lower the article, and the width of the strip pack device does not have to be increased. However, when the affixing position is arranged directly below the conveying means, the moving means becomes an obstacle in order to move the article to the affixing position immediately below the conveying means, so a configuration for removing the conveying means is necessary, There is a problem that the mechanism and operation for that purpose are complicated and the speed cannot be increased.

  Therefore, it is conceivable to arrange the sticking position obliquely downward on the front side in the transport direction with respect to the transport means. According to this, it is not necessary for the moving means to raise the article as in the case where the sticking position is arranged above the conveying means, and the strip pack apparatus is arranged such that the sticking position is arranged on the side of the conveying means. The width does not need to be increased, and the mechanism and operation for moving the article to the pasting position as in the case where the pasting position is arranged directly below the conveying means does not have to be complicated.

  On the other hand, if there are wrinkles at the end of the article to be attached to the mount, not only the appearance of the strip pack will be deteriorated when the article is attached at the end as it is, but also there will be inadequate adhesion such as insufficient adhesion or poor adhesion. Since this may occur, it is conceivable to stretch the edge of the edge before attaching the article to the mount. The strip pack device is provided with the heel-stretching means for that purpose, and the region where the heel is stretched by the heel-stretching means becomes a pasting region on the mount, and the article is pasted on the mount in this pasting region. .

  However, the end portion that stretches the heel with such a heel-stretching means is the end portion on the front side in the conveyance direction of the article. Since the wrinkle-stretching means interferes with an obliquely downward movement path on the front side in the conveyance direction of the article by the moving means, the article cannot be moved obliquely downward on the front side in the conveyance direction from the conveyance means. End up.

  Accordingly, the present invention provides a highly versatile strip pack apparatus that is independent from the upstream apparatus and the downstream apparatus, and is provided with the heel-stretching means so that the article can be smoothly moved to the application position. Is an issue.

In order to solve the above-mentioned problem, the invention according to claim 1 of the present application is a strip pack device for manufacturing a commodity in which an article is attached to a mount, and a conveying means for conveying the article in a substantially horizontal direction, and the conveying means. A wrinkle-stretching means that stretches the wrinkles at the end portion on the front side in the transport direction of the article conveyed by the above, and a moving means for moving the article with the wrinkles at the end portions stretched by the wrinkle-stretching means obliquely downward on the front side in the transport direction When the attaching means for affixing the base sheet was moved article at said end portion, and a crease smoothing saving means for saving the crease smoothing means in the conveying direction forward side during the movement of the article by the moving means comprising this moving means And the heel-stretching means is located above the end portion and extends an heel on the upper surface of the end portion, and on the lower surface of the end portion. Stretch the lower heel And a member, the crease smoothing retracting means may be retracted only the lower crease smoothing member.

Next, the invention according to claim 2 is the strip pack device according to claim 1 , wherein the crease-retracting means retracts the lower crease-stretching member forward in the transport direction. , Being moved substantially horizontally.

Next, the invention according to claim 3 is the strip pack device according to claim 1 , wherein the crease-retracting means retracts the lower crease-stretching member forward in the transport direction. And rotating downward.

Next, the invention according to claim 4 is the strip pack device according to claim 2 , wherein the upper side extending member and the lower side extending member are in contact with the upper surface and the lower surface of the end portion. The upper and lower brushes rotate from the base side to the edge side, and are driven by a driving source to rotate the upper brush, and the lower brush is driven by contacting the driving roller to rotate the lower brush. And a driven roller for moving the lower brush away from the driving roller when the lower brush is moved substantially horizontally by the crease-retracting means.

Next, a fifth aspect of the present invention is the strip pack device according to the fourth aspect , wherein the driving roller is made of metal and the driven roller is made of resin.

  First, according to the first aspect of the present invention, in the strip pack device, the heel-stretching means extends the heel at the end on the front side in the conveyance direction of the article, and the moving means obliquely moves the article on the front side in the conveyance direction. When the article is moved downward, when the article is moved by the moving means, the crease-stretching means is retracted to the front side in the conveyance direction. Even if the moving path of the side obliquely downward interferes, the movement of the article to the pasting position is performed smoothly.

In this case, according to the present invention , when the above-mentioned crease-stretching means has an upper crease-stretching member above the end portion of the article and a lower crease-stretching member below, Since only the lower heel-stretching member with which the part interferes is retracted, the movement of the article to the application position is allowed efficiently and sufficiently with a minimum necessary operation.

Next, according to the second aspect of the present invention, the lower heel-stretching member is retracted to the front side in the conveying direction by moving substantially horizontally, so that the movement of the article to the pasting position is allowed with a simple operation. Will be.

On the other hand, according to the third aspect of the invention, as another aspect, the lower side stretching member is retreated to the front side in the transport direction by rotating downward, and in this case as well, the operation is simple. The movement of the article to the pasting position is allowed.

Next, according to the fourth aspect of the present invention, the lower brush, which is the lower side extending member, is moved to the front side in the conveying direction by moving the lower brush substantially horizontally, and at the same time, the driven roller is separated from the driving roller. As a result, the driven roller stops driving and the retreating lower brush stops rotating, so that even if the end of an article that is moving diagonally downward touches the lower brush by mistake, Thus, such a problem that the wrinkle is re-entered at the end portion where the wrinkle is extended is avoided.

Next, according to the fifth aspect of the present invention, the drive roller is made of metal and the driven roller is made of resin, that is, the fixed side roller that is not retracted is made of hard metal, and the movable side that is retracted is moved. By using a soft resin for the rollers, the pressure contact force between the rollers is improved, and the power transmission between the rollers is favorably performed.

  As shown in FIG. 12, the grip fingers 81 and 81 of the gripping unit 8 place the seal portion Z on the heater 91 of the sticking unit 9 while gripping the seal portion Z at the sticking position P2. In this case, the tape T fed from the tape roll 11 is placed on the heater 91 in advance, and the seal portion Z is overlaid on the tape T. In this state, the seal portion Z and the tape T are sandwiched by the clamp 92, and the bag X is welded to the tape T at the seal portion Z. In the drawing, the symbol R represents a sticking region of the bag X to be attached to the tape T by extending the ridge of the seal portion Z with the brush unit 7.

  As shown in FIG. 13, the control unit 100 of the strip pack device 1 is connected to the conveyors 4 to 6 and the units 7 to 10 so that various signals can be transmitted and received. Next, with reference to FIG. 14, the main operation of the apparatus 1 by the control unit 100 will be described.

  First, the bag X is introduced to the gripping position P1 (step S101), and the seal portion Z of the bag X is stretched (step S102). Next, after gripping the bag X (step S103), the bag X is moved obliquely downward on the front side in the transport direction b (step S104). At that time, as described above, the lower brush 76 of the brush unit 7 retracts forward in the transport direction b (step S105). When the bag X arrives at the affixing position P2, the bag X is affixed to the tape T (step S106), and finally the tape T is fed to discharge the strip pack SP as a product (step S107).

  As described above, in the present embodiment, in the strip pack device 1, the heel-stretching means 7 extends the heel of the end Z on the front side in the conveyance direction b of the article X, and the moving means 8 conveys the article X. When the article X is moved obliquely downward in the front side in the direction b, the crease-stretching means 7 is retracted forward in the transport direction b when the article X is moved by the moving means 8 (see FIG. 9). Even if the heel-stretching means 7 and the moving path 8 on the front side in the conveying direction b of the article X obliquely move downward, refer to FIG. Will be smoothly performed.

  Further, in the case where the crease-stretching means 7 has an upper crease-stretching member 76 above the end Z of the article X and a lower crease-stretching member 76 below (see FIG. 8), Since only the lower side stretching member 76 with which the end Z of the X interferes is retracted (see FIG. 9), the movement of the article X to the sticking position P2 is allowed efficiently and sufficiently with a minimum necessary operation. It will be.

  Further, in that case, the lower heel-stretching member 76 is retracted to the front side in the transport direction b by moving it substantially horizontally (in the direction of the arrow g), so that the movement of the article X to the sticking position P2 can be performed with a simple operation. Will be allowed.

  Further, in this case, the lower brush 76, which is a lower side extending member, is moved substantially horizontally (in the direction of the arrow g) to be retracted to the front side in the transport direction b, and at the same time, the driven roller 79 is moved from the driving roller 78. The drive of the driven roller 79 stops and the rotation of the retracting lower brush 76 stops (see FIG. 9), so that the end Z of the article X moving obliquely downward is mistakenly attached to the lower brush 76. Even if it is touched, the force of stretching the wrinkles does not act on the end Z, and the trouble that the wrinkles enter the end Z where the wrinkles are stretched is avoided.

  Further, the drive roller 78 is made of metal, and the driven roller 79 is made of resin, that is, the fixed-side roller 78 that is not retracted is made of hard metal, and the retractable movable-side roller 79 is made of soft resin. (See FIG. 10), the pressure contact force between the rollers 78 and 79 is improved, and the transmission of power between the rollers 78 and 79 is favorably performed.

  The above embodiment is the best embodiment of the present invention, but various changes and modifications can be made without departing from the scope of the claims. For example, as another mode of retracting the lower heel-stretching member 76, as shown in FIG. 15, the lower heel-stretching member 76 is retracted to the front side in the transport direction b by rotating downward as indicated by an arrow h. It can also be made. Also in this case, the movement of the article X to the sticking position P2 can be permitted with a simple operation. 6 and 12, the gripping device 8 of the strip pack device 1 may grip the end Z from the side of the article X, as indicated by the chain line in the chain line. In that case, the gripping device 8 can grip the vicinity of the region where the heel is stretched by the heel stretching device 7 from the side of the article X.

  According to the present invention, in a highly versatile strip pack apparatus having a configuration independent of the upstream apparatus and the downstream apparatus, the article can be smoothly moved to the pasting position while being provided with the heel-stretching means. Therefore, the present invention is expected to have wide industrial applicability in the technical field of manufacturing strip packs.
