Description

  The present invention relates to a spout mounting method in which a pouch is intermittently transported while being sequentially stopped at each work position, and the spout is attached to the pouch in stages by executing each work at each work position. About.

  For example, as shown to Fig.18 (a), spout S used as a mouthpiece or a mouthpiece was mounted | worn with the upper edge part UE of the pouch P which has the side gusset part formed of flexible sheets, such as a synthetic resin film. In the pouch container SP, a pouch P in which the upper edge portion UE is not heat-sealed is manufactured in advance in a separate process, and the pouch P is spouted on the opened upper edge portion UE of the pouch P as shown in FIG. After inserting S, the upper edge portion UE is heat-sealed, whereby the spout S is attached to the pouch P. The shaded display portion in FIG. 18 shows the heat seal area of the pouch P.

  When the pouch is attached to the pouch step by step by intermittently transporting the pouch to each work position and performing each work at each work position, as shown in FIG. In addition, a series of operations from insertion of the spout into the pouch to heat sealing are performed at the same operation position.

  First, as shown in FIG. 5A, when the pouch P and the spout S are supplied to a predetermined work position, the pair of openers 91 remove the upper edge portion of the pouch P as shown in FIG. After sandwiching and holding, the pair of openers 91 are separated from each other as shown in FIG. Subsequently, after the spout S is inserted into the pouch P from the opened upper edge portion as shown in FIG. 4D, and the pair of openers 91 release the suction as shown in FIG. Separate from each other. Then, as shown in FIG. 5F, the pair of openers 91 descends so as to retract from the upper edge portion of the pouch P, and the pair of seal bars 92 descends to the upper edge portion of the pouch P. As shown in (g), the pair of seal bars 92 sandwich the upper edge portion of the pouch P and heat-seal the spout S to the upper edge portion of the pouch P. Finally, as shown in FIG. 11H, the pair of seal bars 92 are separated from each other and lifted together with the pair of openers 91 to return to the state shown in FIG.

  However, as described above, when a series of operations from insertion of the spout S into the pouch P to heat sealing is performed at the same operation position, a certain amount of time is required after performing the operation of inserting the spout S into the pouch P. In short, since the heat sealing work of the spout S on the pouch P has to be performed, there is a problem that the work of attaching the spout S to the pouch P cannot be accelerated.

  Further, when the operation of inserting the spout S into the pouch P is shifted to the heat sealing operation of the spout S with respect to the pouch P, the pair of openers 91 is retracted from the upper edge portion of the pouch P and the pair of seal bars 92 is Since it takes time to enter the upper edge portion of the pouch P, there is also a problem that the stop time of the pouch P at each work position becomes longer.

  Then, the subject of this invention is providing the spout mounting method which can speed up the mounting | wearing operation | work of the spout to a pouch.

  In order to solve the above-mentioned problem, the invention according to claim 1 is directed to intermittently transporting the pouch to each work position while sequentially stopping the pouch, and performing the respective work at each work position, thereby spouting the pouch. In the spout mounting method in which the mounting of the spout is performed in stages, the spout insertion work into the pouch and the heat sealing work of the inserted spout into the pouch are performed at different work positions, respectively. The present invention provides a spout wearing method characterized by the above.

  According to a second aspect of the present invention, in the spout mounting method according to the first aspect of the present invention, at the spout insertion work position, the spout mounting edge of the pouch is opened by being sucked and held by an opener. After inserting the spout from the spout mounting edge, the suction holding of the spout mounting edge by the opener is released, and the pouch is transported in a state where the part other than the spout mounting edge in the pouch is held.

  As described above, in the spout mounting method according to the first aspect of the present invention, the spout insertion work into the pouch and the heat sealing work into the pouch of the inserted spout are executed at different work positions. Therefore, while performing the heat sealing work of the spout that requires a certain amount of time, the work of inserting the spout into the next pouch can be executed at the previous work position. Therefore, compared with the case where the spout is inserted into the pouch and heat sealed at the same work position, the pouch stop time at each work position can be shortened, and the work of attaching the spout to the pouch is speeded up. It becomes possible.

  In particular, in the invention according to claim 2, the spout mounting edge in the pouch is opened by suction and holding with an opener, and after the spout is inserted through the opened spout mounting edge, the suction holding of the spout mounting edge by the opener is released. Since the pouch is transported while holding the part other than the spout mounting edge in the pouch, it is possible to improve the opening of the spout mounting edge in the pouch when inserting the spout and at the same position. In order to heat-seal the spout to the spout mounting edge of the pouch, as in the case of performing the process from insertion of the spout to the pouch to heat sealing, the seal bar is moved away from the pouch mounting edge of the pouch while the seal bar is retracted. Spout to pouch at the same position without having to enter the mounting edge As compared with the case of performing up to heat seal the insert, it is possible to reduce opener saving time (entry time of the sealing bars), it is possible to shorten the pouch stop time at each work position.

  As described above, in the spout mounting device 1, the spout S is inserted into the pouch P, the heat sealing (first seal, second seal) operation and the spout S are inserted into the pouch P of the inserted spout S. Since the cooling operation of the spout mounting edge of the pouch P is performed at different operation positions, that is, the spout insertion position δ, the first seal position ε, the second seal position ζ, and the cooling position η, a certain amount of time is required. The spout S is inserted into the next pouch P at the spout insertion position δ while the spout mounting edge is cooled at the cooling position η. Can be executed. Therefore, compared with the case where the spout S is inserted into the pouch P at the same work position and the heat sealing and cooling are performed, the stop time of the pouch P at each work position can be shortened, and the spout S to the pouch P is reduced. It is possible to speed up the mounting work.

  In addition, when performing the process from insertion of the spout to the pouch to heat sealing at the same position, in order to heat-seal the spout to the spout mounting edge of the pouch, while retracting the opener such as the suction head from the spout mounting edge of the pouch, Although it is necessary to allow the seal bar to enter the spout mounting edge of the pouch, in this spout mounting device 1, as described above, the spout insertion position δ, the first seal position ε, the second seal position ζ, and the cooling position η are different. Since each work is performed at the work position, it is not necessary to retract the opener from the pouch spout mounting edge or to move the seal bar into the pouch spout mounting edge, and the opener retraction time ( The time required to enter the seal bar can be reduced, so that the pouch P is stopped at each work position. It can be shortened between.

  In particular, in the spout mounting device 1, the heat sealing operation of the pouch P is performed by completely heat-sealing the first sealing operation of mounting the spout S on the pouch P and the spout mounting edge of the pouch P on which the spout S is mounted. Since it is divided into the second sealing work to be closed and executed simultaneously at different work positions, the stop time of the pouch P at each work position can be further shortened.

  Further, in the spout mounting device 1, the pouch P is transported to the spout insertion position δ by sandwiching the position 40mm or more away from the spout mounting edge with the transport belts 38 of the belt transport mechanism 35, and the spout mounting in the pouch P is performed. The edges are opened by being separated from each other while being sucked and held directly by the suction head 46, and the spout S is inserted into the pouch P from the opened spout mounting edge. The openability of the spout wearing edge in the pouch P when inserting is also good.

  In the above-described embodiment, the heat sealing operation of the pouch P includes the first sealing operation of mounting the spout S on the pouch P and the spout mounting edge of the pouch P on which the spout S is mounted by completely heat sealing. However, the present invention is not limited to this, and it is also possible to execute two operations at the same operation position in a single process. is there.

  Further, in the above-described embodiment, the pouch P is transported by sandwiching the position away from the spout mounting edge by the transport belts 38 of the belt transport mechanism 35. However, the present invention is not limited to this. For example, the pouch P can be transported in a state where a position away from the spout mounting edge, such as the bottom of the pouch P, is held by a pair of clampers or the like.

  Further, it goes without saying that the spout mounting method of the present invention can be applied not only to the side gusset type but also to the flat bag type pouch container SP.

  Further, the spout S attached to the pouch P is not limited to the one shown in FIGS. 17A and 17B, and the flat surface fs of the engagement piece ep that holds the conveying posture by contacting the inclined guide 22 or the like. As long as the posture holding portion corresponding to the both end faces es is provided, various shapes can be adopted.
