DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for attaching a spout to an opening of a pouch and sealing the opening to the pouch.

[0002]

2. Description of the Related Art A spout for holding a spout by sealing an opening of the pouch in a state in which one end of a spout for sucking out contents in the pouch is inserted into a bag-like pouch having an open side. The device is widely used.

[0003] This spout mounting device comprises a rotary device in which a plurality of pouch holders are provided at regular intervals around a rotary body that rotates continuously or intermittently at a constant speed in one direction;
Corresponds to a part of the periphery of the rotary, and a pouch supply device for transferring the opened pouch to the pouch holder at a predetermined position, a spout supply device for inserting the spout into an opening of the pouch held by the pouch holder. And a sealing device for sealing the pouch in a range to be performed.

In such a device, the pouch supply device supplies the opened pouches one by one to the pouch holder of the rotary device, where the pouches are suspended and held. As the rotation of the rotary device advances, the spout is inserted into the opening of the pouch from the spout supply device into the pouch held by the pouch holder. Here, the pouch is easily temporarily sealed at the opening, and the upper end of the spout is held at the opening of the pouch.

[0005] The pouch in which the spout is held by the temporary seal is then permanently sealed by a sealing device, and a pouch with the spout is completed. The sealing device
Around the rotary device, it is arranged close to the pouch holder, and when the rotary device rotates intermittently, the seal is performed when the rotary device stops, and the rotary device rotates at a constant speed. Sometimes, the sealing device is provided in the reciprocating swivel device, follows the rotary device at the same speed over a certain range, performs the main sealing during that time, returns to the original position after the sealing, and prepares for the next pouch seal.

[0006]

In the above-mentioned known apparatus, when a spout is inserted and supplied into an opening of a pouch in a pouch holder, the spout is held by the pouch in a short time. The temporary sealing is performed. This is a temporary seal to hold the spout, as the time is too short to complete a full permanent seal here.

Therefore, this known device requires a temporary sealing device for holding the pouch up to the main seal. Furthermore, when the temporary sealing is performed, when the pouch is not in the proper position and posture relative to the spout when the spout is supplied, the pouch temporarily sealed with the spout must be discarded as a defective product, resulting in waste. . Since the pouch is delivered to the pouch holder in a short time, such errors in position and orientation and collapse are likely to occur, and therefore, a relatively large number of pouches with spouts are discarded. Further, in the method of holding the pouch by the temporary seal, the time required for the seal at the time of delivery of the pouch is required, so that it is difficult to increase the performance of the entire spout mounting device.

[0008] The object of the present invention is to provide a spout mounting device having a high capacity without the need for a temporary sealing device which causes such an undesired situation. It is another object of the present invention to provide a spout mounting device that enables the pouch to be used again without discarding the pouch and the spout as defective products.

[0009]

Is in the release position of the two-dot chain line, and the pouch 1 is
It is held only by the side adsorbent 25 (25A and 25B). Such a pouch is appropriately detected by a sensor as to whether it is in a position and posture capable of being sealed, and unsuitable ones are collected without being sealed in a later process, returned to the pouch supply device again, and prepared for reuse. With the rotation of the rotary device 20, the pouch holder 24
Is moved from the position of the pouch supply device 30 to the position of the spout supply device 40, the rotating arm 29 returns to the closed position shown by the solid line in FIG. 4 and FIG. The pouch 1 is largely opened by turning the turning arm 29 to the open position again while adsorbing the pouch by the adsorbing force. With the pouch open, the pouch 1 is brought to the position of the spout supply device 40 and the spout 2 is inserted into the opening of the pouch. Thereafter, the rotating arm 29 returns to the closed position again. The rotating arm 29 is provided with holding members 27A2 and 27B2.
The spout is held via the pouch 1 at the B-shaped portions and the respective V-shaped grooves. When the pouch 1 held by the pouch holder 24 and the holding members 27A and 27B reaches the reciprocating turning device 50 at the time of forward movement moving at the same speed as the rotary device 20, the pouch 1 is moved to the first unit group 51. The primary edge of the opening is sealed (for example, heat sealed), the spout holding portion is secondarily sealed (for example, heat sealed) in the second unit group 52, and the seal portion is cooled in the third unit group. That is, each of the pouches 1 held by the eight pouch holders 24 is primary-sealed at once by the first unit group 51, and during the reciprocation of the reciprocating rotation device 50, the eight pouch holding devices 24 are moved forward again. The body 24 reaches the position of the second unit group 52 where the pouch is secondarily sealed,
While the reciprocating slewing device 50 moves forward again and then moves forward, it reaches the position of the third unit group 53 and the pouch is cooled. The pouch is thus sealed at its opening, whereby the spout is held by the pouch. The spouts with spouts after cooling are taken out one by one by the take-out device 60 and carried out. The pouch with the spout is temporarily stored in a stacker or transported to a filling device by a line, where the contents are filled. When the apparatus of the present embodiment includes a posture correcting member as a preferred embodiment, the suction force of the pouch holder is temporarily released before the spout is supplied, the pouch is in a free state, and the specific side of the pouch is It is brought into a predetermined position and posture by contacting the posture correcting member.

[0034]

As described above, according to the present invention, since the pouch and the spout are held by the holding device until the sealing, the temporary sealing device becomes unnecessary, and the device can be simplified. Further, since the spout can be delivered without a temporary seal, the overall performance of the spout mounting device can be enhanced. In addition, pouches in improper positions and postures are not temporarily sealed and are collected and reused, so that materials can be effectively used, and defective products are drastically reduced.
