  However, in the spout mounting device as described above, even when the pouch P is stacked, the pouch P may be displaced when the pouch P is sucked and held by the suction member 51. In this case, since the pouch is received and supplied to the spout mounting position with the clamper 52 being displaced, there is a problem that the spout S cannot be mounted on the pouch P in an appropriate state.

  Accordingly, an object of the present invention is to provide a spout mounting method capable of reliably mounting a spout at an appropriate position of the pouch with a simple mechanism, a pouch suitable for the spout mounting method, and a pouch forming substrate. .

  In order to solve the above-mentioned problem, the invention according to claim 1 is a pair of openers in which the spout mounting edge of the pouch supplied to the spout mounting position is sucked and gripped by the pair of openers, and then the spout mounting edge is sucked and gripped. In the spout mounting method, the spout mounting edge is opened by opening the spout mounting edges apart from each other, the spout is inserted into the open spout mounting edge, and then the spout is heat sealed to the spout mounting edge. Positioning holes are formed in advance on both outer sides of the mounting part, and before the spout mounting edge of the pouch supplied to the spout mounting position is opened by a pair of openers, a positioning pin is inserted into the positioning hole of the pouch and the pouch is inserted. The spout mounting edge by positioning the two positioning pins relatively close to each other. It has to cause slack between the kick positioning holes is to provide a spout mounting method comprising.

  In order to solve the above-mentioned problem, the invention according to claim 2 is a pair in which the spout mounting edge of the pouch supplied to the spout mounting position is sucked and held by a pair of openers, and then the spout mounting edge is sucked and held. In the spout mounting method in which the spout mounting edge is opened by separating the openers from each other, the spout is inserted into the open spout mounting edge, and then the spout is heat sealed to the spout mounting edge. At least two positioning holes are formed in advance on one outer side of the spout mounting portion of the pouch, and before the spout mounting edge of the pouch supplied to the spout mounting position is opened by a pair of openers, Position the pouch by inserting the locating pin, and the spat at the pouch's spout mounting edge. The other outer side of the mounting part is gripped by a clamper, and the positioning pin and the clamper are brought relatively close to each other, thereby loosening between the positioning hole in the spout mounting edge and the gripping part by the clamper. A spout wearing method is provided.

  In order to carry out the spout mounting method of the invention according to claim 1, a pouch for forming a pouch container with a spout as in the invention according to claim 3, wherein the heat seal is put in a state where the spout is sandwiched. The pouch has a spout mounting edge, and positioning holes are formed on both outer sides of the spout mounting portion at the spout mounting edge. A pouch-forming base material in which the pouches of the invention are continuously connected is used.

  As described above, in the spout mounting method according to the first aspect of the present invention, before the spout mounting edge of the pouch supplied to the spout mounting position is opened by the pair of openers, the positioning pin is inserted into the positioning hole of the pouch and the pouch is mounted. The position of the pouch can be surely prevented, and the positioning pins on both sides can be loosened between the positioning holes by relatively approaching both positioning pins. Therefore, when the spout mounting edge is loosened, the spout mounting edge is preliminarily opened, and the opening operation by the pair of openers performed thereafter can surely open the spout mounting edge.

  In the spout mounting method according to the second aspect of the present invention, before the spout mounting edge of the pouch supplied to the spout mounting position is opened by the pair of openers, the positioning pin is inserted into the positioning hole of the pouch to position the pouch. Therefore, the position of the pouch can be reliably prevented from being displaced, and the positioning pin and the clamper are brought relatively close to each other, thereby loosening between the positioning hole in the spout mounting edge and the gripping portion by the clamper. Thus, when the spout mounting edge is loosened, the spout mounting edge is preliminarily opened, and the spout mounting edge can be reliably opened by the opening operation by the pair of openers performed thereafter.

  As described above, in the spout mounting method according to the first and second aspects of the present invention, the pouch positioning and the preliminary opening of the spout mounting edge in the pouch are performed using a common member. The spout can be securely attached to the appropriate position of the pouch.

  Hereinafter, embodiments will be described with reference to the drawings. FIG. 1 shows a pouch container with a spout in which the spout P shown in FIG. 2 (a) is attached to the pouch P shown in FIG. 2 (c) by the spout attaching method of the present invention.

  As shown in FIG. 1, the pouch P with the spout S attached is a pair of front and back exterior sheets OS and a pair of left and right gussets that are folded inward from both sides of the exterior sheet OS to form left and right gusset portions. The outer periphery of the folded gusset sheet GS is heat sealed to the inner surface of the exterior sheet OS, and the upper and lower edges of the inner surface of the exterior sheet OS are heat sealed to each other. Thus, it is formed in a bag shape. In addition, the upper end portions of both side edges of the gusset sheet GS are formed with cutout portions CP that are mutually matched in a folded state, and the upper end portions on both side edges of the exterior sheet OS are formed through the cutout portions CP. They are partially heat sealed.

  Further, the pouch P before the spout S is mounted is manufactured in a separate process in advance, and as shown in FIG. 2A, the upper edge portion of the exterior sheet OS to which the spout S is mounted is heat-sealed. In addition, positioning holes H are formed in the upper edge portions of the exterior sheet OS and the gusset sheet GS that are heat-sealed to each other when the spout S is mounted on the spout mounting edge that is not heat-sealed. Yes. The shaded display portions in FIGS. 1 and 2A indicate the heat seal portion of the pouch P.

  As shown in FIG. 1 and FIGS. 2 (b) and 2 (c), the spout S has a mouth portion MP for pouring out liquid merchandise filled in the pouch P, and a cross section provided continuously to the mouth portion MP. The shape includes a boat-shaped mounting portion IP and a lead-out portion GP connected to the mounting portion IP. The mounting portion IP is heat-sealed in a state where it is sandwiched between the upper edges of the pouch P.

  Hereinafter, a method for attaching the spout S to the pouch P will be described with reference to FIGS. 3 and 4. First, as shown in FIG. 3 (a), when the standing pouch P and spout S are supplied to the spout mounting position, the tip is formed in a tapered shape as shown in FIG. 3 (b). The positioning pin 11 is inserted into the positioning hole H of the pouch P, and the pouch P is positioned.

  Next, as shown in FIG. 5C, when the positioning pins 11 inserted into the positioning holes H of the pouch P are brought close to each other, the gaps between the positioning holes H at the spout mounting edge of the pouch P are loosened. Then, the unsealed spout mounting edge is preliminarily opened, and then, as shown in FIG. 4D, the pair of openers 12 suck and hold between the positioning pins 11 at the spout mounting edge.

  Then, as shown in FIG. 4A, after the positioning pin 11 is removed from the positioning hole H of the pouch P, the pair of openers 12 are separated from each other at the same time, so that the unsealed spout mounting edge is largely opened. As shown in FIG. 5B, the spout S is inserted into the open spout mounting edge, and finally, the spout S is heat sealed to the spout mounting edge of the pouch P and the spout mounting edges are heat sealed to each other. Thus, the pouch container with a spout shown in FIG. 1 is completed.

  As described above, in this spout mounting method, just before the spout mounting edge of the pouch P supplied to the spout mounting position is opened by the pair of openers 12, the positioning pin 11 is inserted into the positioning hole H of the pouch P to insert the pouch P. Therefore, it is possible to reliably prevent the displacement of the pouch P when the spout S is inserted.

  Further, the positioning pins 11 inserted into the positioning holes H of the pouch P are brought close to each other and loosened between the positioning holes H in the spout mounting edge, so that the spout mounting edge is preliminarily opened. Therefore, the spout mounting edge can be reliably opened by the opening operation by the pair of openers 12 performed thereafter.

  Moreover, since the positioning of the pouch P and the preliminary opening of the spout mounting edge in the pouch P are performed using the positioning pin 11 which is a common member, the spout S can be surely placed at the appropriate position of the pouch P with a simple mechanism. Can be worn.

  Moreover, since the positioning hole H is formed in the unsealed spout mounting edge in the pouch P, the opening operation by the pair of openers 12 can open the spout mounting edge to the maximum, and the spout S can be smoothly and smoothly opened. Can be inserted reliably.

  In the above-described embodiment, the positioning pins 11 inserted into the positioning holes H of the pouch P are brought close to each other so as to loosen the space between the positioning holes H at the spout mounting edge of the pouch P. However, the present invention is not limited to this, and only one positioning pin 11 may approach the other positioning pin 11 side.

  Further, in the above-described embodiment, the pair of openers 12 suck and grip between the positioning pins 11 at the spout mounting edge in a state where the space between the positioning holes H at the spout mounting edge of the pouch P is loosened. However, if the amount of loosening between the positioning holes H is large, the pouch P may be displaced if the pair of openers 12 sucks and holds the spout mounting edges while the positioning holes H are loosened. Therefore, after the spout mounting edge of the pouch P is preliminarily opened by bringing the positioning pins 11 relatively close to each other, the positioning pin 11 is returned to the original positioning state, and the spout mounting edge is not loosened. In this state, it is preferable to cause the opener 12 to suck and hold the spout mounting edge.

  Further, in the above-described embodiment, the positioning holes H are formed so as to cover the pair of left and right gusset sheets GS that are folded inward from both side portions of the both exterior sheets OS, but the present invention is not limited to this. It is also possible to form a positioning hole between the two gusset sheets GS so as to avoid the gusset sheets GS.

  In the above-described embodiment, the positioning hole H is formed in the spout mounting edge that is not heat-sealed. However, the present invention is not limited to this, and the side edges of the exterior sheet OS and the gusset sheet GS are heat-sealed. You may form a positioning hole in the upper end part of the made side seal part.

  Further, in the above-described embodiment, the positioning holes H are formed on both outer sides of the spout mounting portion at the spout mounting edge of the pouch P. However, the present invention is not limited to this, and the pouch P1 shown in FIG. At least two positioning holes H may be formed on one outer side of the spout mounting portion at the spout mounting edge. In that case, as shown in FIGS. 6 (a) to 6 (d), the positioning pin 11 is connected to the pouch P1. In the state where the pouch P1 is positioned, the other outside of the spout mounting portion at the spout mounting edge of the pouch P1 is gripped by the clamper 13 so that the positioning pin 11 and the clamper 13 are relative to each other. , The space between the positioning hole H in the spout mounting edge and the gripping portion by the clamper 13 may be loosened.

  In addition, the pouches P and P1 may be supplied in a single-wafer state, but as shown in FIGS. 7A and 7B, a long belt-like pouch forming base in which the pouches P and P1 are continuously connected. The materials M and M1 are supplied in a rolled state, and before the spout S is mounted, the pouches P and P1 are formed by sequentially cutting the pouch-forming base materials M and M1 into predetermined shapes while feeding them out. You may make it do. In addition, the dashed-two dotted line in the same figure (a), (b) has shown the boundary of the part corresponded to the pouch P and P1 which were connected continuously.

  In the above-described embodiment, the side gusset type pouch has been described. However, the present invention is not limited to this, and the present invention can be applied to a bottom gusset type pouch or a pouch that does not have a gusset portion. Needless to say. Unlike the above-described pouch-forming base materials M and M1, the pouch-forming base material that forms the bottom gusset-type pouch is in a state where the side edges of the pouch are connected to each other.
