Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a bag carrier such as a self-supporting flexible bag.

[0002]

2. Description of the Related Art As a carrier for accommodating a self-supporting flexible bag and carrying it on a content filling line, both side edges of two side sheets of a bag described in JP-A-57-77417 are inserted. Some have a groove member for holding and a belly receiving member for holding and holding the two side sheets of the bag body.

According to this carrier, both side edges of the bag are inserted and held in the groove of the groove member, and the side sheets are held and held by the belly receiving member, thereby accommodating the bag accommodated in the carrier. The posture is regulated to make the direction constant, the bag is filled with the contents while the upper end of the bag is open, and then the upper end of the side sheet of the bag is sealed by sandwiching it with a seal bar. To wear.

[0004]

In the conventional carrier, 2
Since the groove shape of the groove member for inserting and holding the both side edges of the side sheets is a narrow straight shape, the operability of inserting the bag body is poor.

SUMMARY OF THE INVENTION It is an object of the present invention to improve the operability of inserting a bag carrier for regulating a storage posture.

[0006]

SUMMARY OF THE INVENTION The present invention provides at least 2
A bag carrier for accommodating a bag formed by laminating two side sheets at both side edges thereof, wherein a groove for accommodating the side edge is provided at an interval shorter than the width of the side sheet of the bag. In addition, a wall portion that regulates the accommodation position of the side sheet is provided, and a taper portion is provided at each of the groove portion and the upper portion of the wall portion, the upper portion of which extends outward, and an angle formed by the taper portion of the groove portion with respect to the vertical line is formed by the wall portion. Is set smaller than the angle formed by the tapered portion with respect to the vertical line.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A carrier 10 shown in FIGS. 1 to 3 contains a bag 1 of a self-supporting flexible bag and is used for carrying a detergent or the like in a content filling line or the like.

In the bag 1, a bottom sheet 3 is attached to a lower portion of two side sheets 2, and edges 2A on both sides of both sheets 2 are attached. Fill the contents from the opening 4 of the bag 1,
Thereafter, the opening is heat-sealed and bonded and sealed.

The carrier 10 is made of, for example, a synthetic resin, and has a bottom portion 12 at a lower portion of a body portion 11 and a bag insertion opening 1 at an upper portion.
3 is provided with a bag housing portion 14 inside.

The carrier 10 is provided with a bag housing portion 14 of the body 11.
A pair of left and right groove portions 16 is provided on both sides facing each other, and a pair of front and rear wall portions 17 facing each other between the two groove portions 16 are provided. The groove 16 has a round hole groove shape, and the two edges 2 of the bag 1 are stored in a state where the bag 1 is housed in the bag housing portion 14.
The accommodating position of these two edges 2A is regulated so that the interval W of A is shorter than the width of the side sheet 2 (to open the opening 4). The wall portion 17 regulates the housing position of the side sheet 2 in a state where the bag body 1 is housed in the bag housing portion 14.

The carrier 10 has tapered portions 16A and 17A, which are upwardly and outwardly outwardly, respectively, at portions above the groove 16 and the wall 17 and surrounding the bag insertion opening 13. The taper angle θ1 formed by the tapered portion 16A of the groove 16 with respect to the vertical line (the longitudinal axis direction of the carrier 10) is smaller than the taper angle θ2 formed by the tapered portion 17A of the wall portion 17 with the vertical line. Then, the angle of the tapered portion, which is the bag body guiding means, provided above the accommodation portion that regulates the shape formed by the groove portion 16 and the wall portion 17 with respect to the vertical direction, is set to the groove portion, ie, both side edges of the bag body. Is larger above the place where the sheet is inserted and held, and larger above the wall, that is, the place above the position where the accommodation position of the bag-side sheet is regulated (FIGS. 2 and 3).

The carrier 10 is used as follows. (1) With the carrier 10 positioned at the bag insertion station, the empty bag 1 is inflated by filling with compressed air, and the bag 1 is inserted into the bag container 14 of the carrier 10. At this time, both side edges 2A of the bag 1 are guided to the tapered portion 16A of the groove 16 to be inserted and held in the groove 16, and both sheets 2 of the bag 1 are tapered by the tapered portion 17A of the wall 17.
And the shape is held by the wall portion 17.

(2) The transporter 10 is transported to the filling station, and the bag 1 accommodated in the transporter 10 is filled with contents such as detergent.

(3) The transporter 10 is transported to the sealing station, and the upper end of the side sheet 2 of the bag 1 accommodated in the transporter 10 is sealed by sandwiching it with a seal bar or the like.

(4) The carrier 10 is transported to the bag discharging station, and the bag 1 is discharged from the carrier 10.

Therefore, according to the carrier 10, the following:
Has the effect of The accommodating position of the side edges 2A of the two side sheets 2 is regulated by the groove 16 of the carrier 10 and the accommodating position of the side sheet 2 is regulated by the wall 17. At this time, the housing position of the two edges 2A of the bag 1 is regulated by the groove 16 so that the distance W between the two edges 2A is shorter than the width of the side sheet 2. The opening 4 formed by the upper end of the opening stably maintains the opened state. That is, the conveying tool 10 can regulate the accommodation posture of the bag body 1 to make the directionality constant.

The carrier 10 includes a groove 16 and a wall 1 for regulating the edge 2A of the bag 1 and the accommodation position of the side sheet 2, respectively.
Each of the upper portions of the upper portion 7 has a tapered portion 16A,
7A, the entirety of the bag body 1 is
It can be smoothly inserted by being guided by 6A and 17A.

Since the taper angle θ1 of the tapered portion 16A of the groove portion 16 is smaller than the taper angle θ2 of the tapered portion 17A of the wall portion 17, when the bag 1 is inserted into the carrier 10, the bag 1 As a result, the hard edge 2A comes into contact with the tapered portion 16A of the groove 16 first and starts guiding. That is, the carrier 10 is provided at the edge 2 </ b> A of the bag 1.
Is reliably and firstly introduced into the groove 16 without being displaced from the groove 16, giving the bag 1 an insertion directionality, and making the insertion of the bag 1 smoother.

[0019]

As described above, according to the present invention, it is possible to improve the operability of inserting a bag in a bag-conveying device capable of restricting the storage posture of the bag.
