It is possible to hold the spout and the bag body by restricting the movement rotating around the center. Also, since the spout holding member can hold the spout without contacting the spout's intermediate shaft with the vertical movement or rotation of the spout restricted, the diameter of the spout's tubular part or intermediate shaft can be reduced. Can be different. That is, if the first flanges have the same size, spouts having different caliber sizes can also be held.

In addition, when the predetermined thickness is formed to be smaller than the distance between the bottom surface of the first flange and the top surface of the second flange, the bottom surface of the first flange is set to the first surface in the vertical direction. It becomes easy to put on the mounting surface of the member. That is, as long as it is within the range between the first flange and the second flange in the vertical direction, even if the relative position with respect to the first member is slightly deviated, the intermediate shaft portion is cut off from the first member. Can be inserted into the notch. This makes it easy to prevent the spout-holding member from falling off when the spout-equipped bag body is transferred from another transport device.

Further, it is possible to contact an end portion of a region of the positioning portion which is capable of contacting a part of the side surface of the first flange, and a portion of a top surface of the second member which is on the side end side of the first flange. From the end of the region to the tip of the first member, the distance between the surfaces facing each other across the notch is the distance between the surfaces facing each other across the notch in the second member. When the third member is formed to be larger than the distance, the bottom surface of the first flange is easily placed on the placement surface of the first member in the vertical direction and the horizontal direction. That is, when the intermediate shaft portion is inserted into the notch, the third member has a wider frontal area in the vertical direction and the horizontal direction than the area surrounded by the second member and the positioning portion on the mounting surface. Becomes Therefore, even if the position of the first flange with respect to the region surrounded by the second member and the positioning portion is slightly displaced, the intermediate shaft portion can be inserted into the notch of the first member. This makes it easy to prevent the spout-holding member from falling off when the spout-equipped bag body is transferred from another transport device.

The lower holding member 2 has a substantially U-shaped cutout 21 in plan view from the front end side toward the base end side (see FIGS. 1 to 3 ). Further, the lower holding member 2 is formed with a substantially flat mounting surface 22 on which the lower surface 61a of the upper flange 61 is mounted.

The inner diameter of the notch 21 of the lower holding member 2 is larger than the outer diameter of the intermediate shaft portion 63 (see FIG. 6(a)) that forms the body portion between the upper flange 61 and the lower flange 62 of the spout 6. Is formed in. The notch 21 is a portion that serves as a passage through which the intermediate shaft portion 63 moves from the distal end side to the proximal end side when receiving the spout-equipped packaging container from a separate transport device.

Here, the shape of the notch 21 is not particularly limited as long as the spout holding member A can hold the spout 6 and its movement in the vertical direction and the horizontal direction is restricted only by the upper flange 61. is not.

Further, the spout holding member A has a positioning portion 5 formed on the mounting surface 22 in the vicinity of the peripheral edge of the end of the notch 21 (see FIGS. 1 to 3 ).

The positioning portion 5 includes a base end surface 61b of the upper flange 6 (see FIGS. 4A and 5A) and two side end surfaces 61c (FIG. 4B and FIG. 5B) connected to the base end surface 61b. (see b)), and is a member that regulates the movement of the upper flange 6 toward the base end side and the movement in the left-right direction (including the rotational movement about the axis).

The base end surface 61b of the upper flange 6 referred to here corresponds to one end surface of the first flange in the claims of the present application. Further, the two side end faces 61c connected to the base end face 61b of the upper flange 6 referred to here correspond to the side end faces of the first flange in the claims of the present application.

The positioning portion 5 has a base end positioning portion 51 that abuts the base end surface 61b of the upper flange 6 and two side end positioning portions 52 that abut the two side end surfaces 61c of the upper flange 6 ( (See FIG. 2).

A curved surface portion 53 is formed between the base end positioning portion 51 and the side end positioning portion 52 so as to match the shape of the end surface of the upper flange 6 (see FIG. 2 ).

The base end positioning portion 51, the two side end positioning portions 52, and the curved surface portion 53 are erected vertically upward from the substantially flat mounting surface 22. Further, the vertical lengths of the base end positioning portion 51, the two side end positioning portions 52, and the curved surface 53 are formed to be slightly larger than the thickness of the upper flange in the vertical direction.

Here, the shapes and sizes of the base end positioning portion 51, the side end positioning portion 52, and the curved surface portion 53 are in contact with the upper flange 61 so that movement in the horizontal direction can be regulated, and the mounting surface 22 is also included. With the upper holding portion 3, there is no particular limitation as long as the movement of the upper flange 61 in the vertical direction can be restricted.

Further, the spout holding member A is provided with an upper holding member 3 from the upper end of the positioning portion 5 toward the tip side and the center side.

The upper holding member 3 includes a base end pressing portion 31, two side end pressing portions 32, and a curved surface portion 33. The upper holding member 3 is a member that restricts the vertical movement of the upper flange 6 while the positioning portion 5 restricts the movement of the upper flange 6 toward the base end and the movement in the left-right direction. ..

More specifically, the base end pressing portion 31 is formed from the upper end of the base end positioning portion 51 of the positioning portion 5 toward the distal end direction. Further, the side end pressing portion 32 is formed from the upper ends of the two side end positioning portions 52 of the positioning portion 5 toward the center. Further, a curved surface portion 33 is formed between the base end pressing portion 31 and the side end pressing portion 32 (see FIGS. 1 and 2).

With the positioning portion 5 restraining the movement of the upper flange 6 toward the base end side and the movement in the left-right direction, the base end holding portion 31 is provided with the upper surface 61d of the base end side edge portion of the upper flange 6. The contact length is formed. Further, in the same state, the two side end pressing portions 32 are formed on the upper surface of the edge portion on the side end side of the upper flange 6 and in such a length as to abut on a partial region 61e on the base end side. ..

Here, the shapes and sizes of the base end pressing portion 31, the side end pressing portion 32, and the curved surface portion 33 are in contact with the upper flange 61, and together with the mounting surface 22 and the positioning portion 5, in the vertical direction of the upper flange 61. Is not particularly limited as long as it can regulate the movement of the.

Further, in the spout holding member A, the front end portion 7 is formed continuously with the side end positioning portion 52 and the side end pressing portion 32 (see FIGS. 1 and 2). The front portion 7 is formed on both sides in the left-right direction with the notch 21 in between.

Further, the distance W1 between the facing surfaces of the front face portion 7 is formed larger than the distance W2 between the facing surfaces of the side end positioning portion 52 (see FIG. 2). Further, in the area sandwiched by the frontage portions 7, the upper surface of the upper flange 61 does not contact any area of the spout holding member A, and the frontage portion 7 has a shape in which the upper portion is open.

That is, in the work in which the base end of the upper flange 61 is inserted toward the base end positioning portion 51, even if the position of the upper flange 61 is slightly displaced in the horizontal direction and vertically upward, it is directed toward the base end side. It becomes possible to insert it. As a result, in the work of delivering the packaging container with the spout to the content filling device from another device, the work can be smoothly performed. In addition, it is possible to prevent the packaging container with the spout from failing and failing to be delivered.

Further, the thickness of the lower holding member 2, that is, the length in the vertical direction, is the distance between the upper flange 61 and the lower flange 62 of the spout 6 (between the bottom surface 61 a of the upper flange 61 and the upper surface of the lower flange 63). Is smaller than the distance).

With such a structure, when the intermediate shaft portion 63 of the flange 6 is inserted into the notch 21 and the flange 6 is moved from the distal end side to the proximal end side, the lower holding member 2 causes the upper flange 61 and the lower flange. It is easy to move in between 62.

The protruding portion 41 is provided on the tip side of the left frontage portion 7. The leaf spring 43 is a spring member that biases the stopper body 42 in a direction in which the protruding portion 41 faces the center.

With the positioning portion 5 restraining the movement of the upper flange 6 toward the base end side and the movement in the left-right direction, the protruding portion 41 of the stopper 4 is part of the tip surface of the upper flange 6 (not shown). And the movement of the upper flange 61 in the front end direction is restricted.

Among the members described above, the main body 1, the lower holding member 2, the upper holding member 3, and the positioning portion 5 are made by integrally molding the same metal.

When the peripheral structure of the notch 21 of the spout holding member A is side-viewed from the above-described configuration, a part of the mounting surface 22 of the lower holding member 2, the positioning portion 5, and the upper holding member 3 form a substantially rectangular shape. A letter-shaped space is formed (see FIG. 3).

In the side view, a part of the upper flange 61 is arranged in the substantially U-shaped space, and the base end surface 61b, a part of the lower surface 61a, and the upper surface 61d of the edge portion on the base end side are suppressed. Thus, the upper flange 6 is held by the spout holding member A (see FIGS. 4A and 5A).

Similarly, the side end 61 c of the upper flange 61 is also held by a part of the mounting surface 22 of the lower holding member 2, the positioning portion 5 and the upper holding member 3. That is, a part of the side end surface 61c of the upper flange 61, a part of the lower surface 61a, an upper surface of the edge portion on the side end side, and a part of the region 61e on the base end side are suppressed, and the upper flange 6 is spouted. It is held by the holding member A (see FIGS. 4B and 5B).

That is, with respect to the spout 6 of the spout-equipped packaging container, a part of the upper flange 61 thereof abuts the spout holding member A, whereby the spout-equipped packaging container is held and movement in the horizontal and vertical directions is restricted. Will be done. Further, the stopper 4 prevents the upper flange 61 from slipping out in the front end direction.

4 and 5 show the shape of the spout 6 which can be held by the spout holding member A to which the present invention is applied. The difference between the spouts 6 shown in FIGS. 4 and 5 lies in the size of the diameter of the through hole penetrating the spout in the vertical direction.

Hereinafter, a flow of delivering the spout to the contents filling device and holding the spout using the spout holding member A to which the present invention is applied will be briefly described.

First, a packaging container with a spout is conveyed from the previous step of the content filling device, and, for example, a conveying arm (not shown) that constitutes the device of the previous step and holds the container is attached to the spout holding member A. Adjacent. Then, the part of the spout 6 moves toward the notch 21 of the spout holding member A by the action of applying vibration from the transfer arm or being pushed out by the arm.

When the spout 6 comes close to the tip of the notch 21A of the spout holding member A, a mounting arm (not shown) provided on the content filling device side grips the spout 6 and directs it toward the main body 1 side. And pull to transport.

At this time, the bottom surface 61a of the upper flange 61 abuts on the mounting surface 22 of the holding member 2, and moves toward the main body 1 side in such a manner that the upper flange 61 is transferred from the apparatus in the entire process. Further, the intermediate shaft portion 63 of the flange 6 is inserted into the notch 21 and moves from the tip end side to the base end side. Further, the tip end portion of the lower holding member 2 passes between the upper flange 61 and the lower flange 62 with the intermediate shaft portion 63 sandwiched by the notches 21.

The base ends of the upper flanges 61 reach the tips of the two side end pressing portions 32, pass thereunder, and further proceed to the main body 1 side. Then, when the base end surface 61b of the upper flange 61 comes into contact with the base end pressing portion 31, the movement of the flange 6 is completed.

At the position where the base end surface 61b of the upper flange 61 abuts the base end pressing portion 31, the tip end side of the upper flange 6 and a part of the side end contact the mounting surface 22, the positioning portion 5, and the upper holding member 3. In contact with each other, the upper flange 6 is held in the vertical direction and the horizontal direction, and its position is determined. Further, at the same position, the movement toward the distal end side is more reliably regulated in the direction connecting the distal end and the proximal end through the stopper 4.

Further, in the contents filling device, operations such as opening the bag of the packaging container and filling the contents are performed. For example, the spout holding member A is directed toward the device that carries out the next step such as mounting the cap. The packaging container with the spout is delivered from. With the above-described flow, the spout holding member A holds the spout-equipped packaging container.

Here, in the present embodiment, when the base end surface 61b of the upper flange 61 is in contact with the base end pressing portion 31, the intermediate shaft portion 63 of the spout 6 starts the lower holding member 2 and the spout holding member A. It does not come into contact with any part.

Further, the lower flange 62 of the spout 6 does not come into contact with any part of the spout holding member A. That is, only by the contact between the upper flange 61 and the spout holding member A, the holding of the spout 6 and the regulation of the movement in the vertical direction and the horizontal direction are carried out.

According to this, it is possible to freely change the diameter of the intermediate shaft portion 63 as long as the diameter is within the range of the inner circumference of the notch 21.

Also, regarding the length of the intermediate shaft portion 63, if the distance between the upper and lower flanges into which the lower holding member 2 can be inserted is set, it is possible to freely change the length.

Further, for example, in the vertical direction, the length required for the spout holding member A to hold the spout 6 is indicated by the symbol Y1 in FIG. 6A. Further, in FIG. 6B, the length required for the conventional spout holding member to hold the spout 100 is indicated by a symbol Y2. Reference numeral 64 indicates a fusion portion to which the pouch is fixed by heat fusion, and reference numeral 65 indicates a tubular portion to which the cap is attached. Further, reference numeral 101 is an upper flange, reference numeral 102 is a lower flange, and reference numeral 103 is an intermediate shaft portion.

In short, in the spout holding member to which the present invention is applied, the size and shape of the other parts of the spout can be appropriately changed as long as the length shown by the symbol Y1 can be grasped in the vertical direction. That is, the spout can be shortened in the longitudinal direction.

Furthermore, in the spout holding member to which the present invention is applied, the shape of the spout to be held can be a spout in which only the upper flange is provided and the lower flange is not formed.

That is, since the spout holding member A has only the upper flange 6 to hold the spout 6 and regulate the movement thereof in the vertical direction and the horizontal direction, the selection range of the shape and size of the spout to be held is widened. It becomes possible.

Further, only by attaching one spout holding member A to the content filling device, it is not necessary to replace the spout holding member with another structure according to the shape and size of the spout. This not only saves the labor for attaching and detaching the spout holding member, but also leads to a reduction in the cost of manufacturing the spout holding member in a timely manner.

In addition, since the spout holding member A has only the upper flange 6 and holds the spout 6, when the contents filling device is in operation and the spout 6 is loaded by an external force for some reason, the spout holding member A Can reduce the risk of damage. That is, since the area other than the upper flange 6 is not in contact with the spout holding member A, the generated stress is likely to concentrate on the upper flange 6, and the spout 6 side is damaged first even when an excessive force is applied. As a result, it is possible to prevent a problem such as bending of the spout holding member A from occurring.

As described above, the spout holding member according to the present invention has a high degree of freedom in the shape and diameter of the spout in the packaging container with the spout to be held, and has a simple structure, but is capable of sufficiently holding the spout. Has become.
