FIG. 2 is a perspective view showing an example of a chute applicable to the above embodiment. FIG. 3 is a diagram showing an example of a chute applicable to the above embodiment.

The best mode for carrying out the pillow back-in-box manufacturing apparatus and method according to the present invention will be described below with reference to the drawings. FIG. 1 shows a schematic diagram of a manufacturing apparatus for a pillow-type back-in box according to the present invention, which is configured by storing a pillow-type inner bag in an outer box. As shown in FIG. 1, the pillow-type back-in-box manufacturing apparatus 1 drops a pillow-type inner bag 2 filled with a liquid by its own weight toward an outer box 3 mainly composed of cardboard or the like. A chute 4 is provided for storage in the outer box 3.

The pillow-type inner bag 2 is composed of, for example, a double film, and the inside thereof is filled with various liquids such as drinking water, food, sake, dairy products, and pharmaceuticals. . The pillow-type inner bag 2 has a spout 2a protruding from the outer surface of the upper surface. The pillow-type inner bag 2 filled with a liquid in advance is transported to the chute 4 by a conveyor 19 as a transport means disposed on the upstream side of the pillow-type back-in-box manufacturing apparatus 1. More specifically, in the pillow-type inner bag 2 filled with the liquid, the spout 2a is disposed at the upper center position (upper position) and at the rear center position in the transport direction (indicated by the arrow 20 in FIG. 1). In this state, the conveyor 19 transports the chute 4 to the inlet opening 6.

As shown in FIG. 2, the chute 4 has a generally cylindrical shape. As shown in FIG. 2, the chute 4 is opposed to the upper surface 4a, the lower surface 4b disposed to face the upper surface 4a, the left side surface 4c, and the left side surface 4c. It has a body 5 defined by a right side surface 4d arranged. The main body 5 includes an inlet opening 6 through which a pillow-type inner bag 2 filled with liquid flows and an outlet opening 7 through which the pillow-type inner bag 2 filled with liquid flows out through the main body 5 of the chute 4. And have. The outlet opening 7 is formed in an opening smaller than the inlet opening 6, and can be formed to have a width dimension of about 90 percent of the width of the outer box 3, for example.

The upper end of the upper surface 4a is set longer than the upper end of the lower surface 4b. With this configuration, the pillow-type inner bag 2 filled with the liquid can be smoothly flowed into the main body 5 of the chute 4 from the inlet opening 6.

The upper surface 4a of the main body 5 protrudes from the inner surface of the upper surface 4a of the main body 5 toward the outer surface along a center line 8 as a line extending from the inlet opening 6 to the outlet opening 7 on the upper surface 4a of the main body 5. Accordingly, a concave groove along the center line 8 is formed on the inner surface of the upper surface 4 a of the main body 5. As will be described later, the concave groove along the center line 8 guides the spout 2a from the inlet opening 6 to the outlet opening 7 and fills the pillow-type inner bag 2 filled with the liquid passing through the main body 5 of the chute 4. It is for dropping while holding the posture so as not to collapse.

The lower surface 4b of the main body 5 is disposed so as to be parallel to the upper surface 4a. Furthermore, the distance (distance) from the position of the center line 8 on the inner surface of the upper surface 4a to the lower surface 4b is a direction orthogonal to the transport direction of the pillow type inner bag 2 filled with the liquid transported to the inlet opening 6. Is set so as to correspond to the dimension from the bottom surface of the inner bag to the upper surface of the spout 2a (width dimension indicated by reference numeral 21 in FIG. 1). With this dimension setting, the pillow type inner bag 2 filled with the liquid passing through the main body 5 of the chute 4 has a pour spout 2a having a concave shape along the center line 8 in a state where no extra space (gap) is provided. The main body 5 of the chute 4 can be passed through while being guided by the groove and without changing the posture of the inner bag 2.

Further, as shown well in FIG. 1, the chute 4 is in the direction of conveyance of the pillow-type inner bag 2 filled with the liquid to be conveyed to the inlet opening 6 (the arrow direction indicated by reference numeral 20 in FIG. 1). It is arranged at an angle. As shown by the dotted line in FIG. 1, this chute 4 is in the transport direction of the pillow-type inner bag 2 filled with the liquid transported to the inlet opening 6 (the arrow direction indicated by reference numeral 20 in FIG. 1). It is provided so as to be movable in the vertical direction with respect to the installation surface 30 of the pillow type back-in-box manufacturing apparatus 1 in a state where it is inclined at a predetermined angle. When the chute 4 is used (when the pillow-type inner bag 2 filled with liquid is dropped toward the outer box 3 through the chute 4 and stored in the outer box 3), the chute 4 is shown by a broken line in FIG. 1 is moved down from the indicated position and arranged at the position indicated by the solid line in FIG. 1, while when not in use (the pillow-shaped inner bag 2 filled with liquid falls toward the outer box 3 through the chute 4. When not), the robot moves upward from the position indicated by the solid line in FIG. 1 to the position indicated by the broken line in FIG. Here, a position indicated by a broken line in FIG. 1 is set to a position that does not interfere with at least a flap described later. On the other hand, the position indicated by the solid line in FIG. 1 is that the lower ends of the upper surface 4a, the lower surface 4b, the left side surface 4c, and the right side surface 4d of the main body 5 of the chute 4 are separated from the storage port 9 described later by a predetermined dimension. 3 is a position arranged in a state of entering into 3.

Next, the outer box 3 will be described. The outer box 3 has a substantially cubic outer shape, and the outer box 3 shown in FIG. 1 has a pillow-type inner bag 2 filled with a liquid dropped toward the outer box 3 through the chute 4. The storage port 9 for storing is opened and inclined at the same inclination angle as the inclination angle of the chute 4. That is, the outer box 3 is arranged so that the direction orthogonal to the bottom surface of the outer box 3 is substantially equal to the falling direction of the pillow-type inner bag 2 filled with the liquid in the chute 4. Therefore, the outer box 3 is disposed at an inclination angle with respect to the installation surface 30 of the pillow type back-in-box manufacturing apparatus 1 at the same inclination angle as the chute 4.

Alternatively, the outer box 3 has a state in which the storage port 9 for storing the pillow type inner bag 2 filled with the liquid dropped toward the outer box 3 through the chute 4 is opened, and the chute It is also possible to arrange them at an inclination angle different from the inclination angle of 4. Whether the inclination angle of the outer box 3 is the same as that of the chute 4 or a different inclination angle, and the numerical values of the inclination angle of the outer box 3 and / or the inclination angle of the chute 4 are the material of the inner bag 2 In consideration of the temperature of the liquid filled in the inner bag 2 and the like, the inner bag 2 is set in advance so that the inner bag 2 can be dropped and stored in a desired position in the outer box 3 by its own weight. Can do.

The outer box 3 has at least one flap for closing the storage port 9, and the illustrated outer box 3 has a front flap 10, a rear flap 11, a right flap (not shown), and a left side. It has four flaps with flaps (not shown). The front flap 10 of at least one flap (four outer boxes 3 in the figure) is stored in the outer box 3 when the pillow type back-in box is opened (in use). In order to take out the spout 2a of the inner bag 2 out of the outer box, a take-out area (not shown) is formed at a position corresponding to the spout 2a. The removal area can be defined by perforations, for example.

The outer box 3 is disposed so as to be inclined so that the front flap 10 in which the take-out region is formed is located below the upper surface 4a in which the concave groove is formed. The inclined state of the outer box 3 is held by guide means 12 provided at a desired location on a part 22 of a conveyor (not shown) that conveys the outer box 3 of the pillow type back-in-box manufacturing apparatus 1. It has become. The position of the guide means 12 can be adjusted.

Further, at a desired location of the pillow type back-in-box manufacturing apparatus 1, the outer flap 3 is held in a position where it does not interfere with the upper surface 4 a of the chute 4 due to the front flap 10 falling in the closing direction (inward direction) due to the inclined arrangement of the outer box 3. A flap holding means 13 is provided. The flap holding means 13 prevents the front flap 10 from falling in the closing direction (inward direction), and the front flap 10 is held at a position where it does not interfere with the upper surface 4a of the chute 4, thereby producing a pillow type back-in box. The front flap 10 is prevented from interfering with the vertical movement of the chute 4 in the vertical direction with respect to the installation surface 30 of the apparatus 1.

The outer box 3 is held by the flap holding means 13 and tilted at a desired angle when the pillow-type inner bag 2 filled with the liquid dropped toward the outer box 3 through the chute 4 is stored. Before and after the storage, the pillow-type back-in-box manufacturing apparatus 1 is disposed horizontally with respect to the installation surface 30. This inclination movement of the outer box 3 is performed together with the guide means 12 by a suitable means such as a cylinder 23 provided at a desired position of the apparatus 1 by a part 22 of a conveyor (not shown) for conveying the outer box 3. It can be realized by being inclined.

Next, the operation of the above embodiment will be described. First, the outer box 3 sequentially transports a plurality of outer boxes 3 in an empty state in which the inner bag 2 is not stored and in a state in which the storage port 9 is opened, that is, four flaps are opened. 1 is conveyed in a direction perpendicular to the paper surface in FIG. 1 (horizontal direction with respect to the installation surface 30 of the pillow-type back-in-box manufacturing apparatus 1) by a conveying conveyor (not shown). Stopped at a predetermined position. At this time, the chute 4 is disposed at a raised position indicated by a broken line in FIG. In this state, the outer box 3 is inclined to a desired position while being held by the guide means 12 due to the inclination of the part 22 of the conveyor. At this time, the front flap 10 is held at a position not interfering with the upper surface 4a of the chute 4 by the flap holding means 13 below the upper surface 4a.

In this state, the chute 4 is moved downward from the position indicated by the broken line in FIG. 1 and is disposed at the position indicated by the solid line in FIG. 1, whereby the upper surface 4a and the lower surface 4b of the main body 5 of the chute 4 are moved to the left side. The lower end portions of the surface 4c and the right side surface 4d are arranged in a state of entering the outer box 3 from the storage port 9 by a predetermined dimension. During the downward movement, the two right side flaps (not shown) and the left side flaps (not shown) are further opened outward by contacting the left side surface 4c and the right side surface 4d. ing. The rear flap 11 is prevented from falling in the closing direction (inward direction) by the lower surface 4b.

Moreover, the pillow type inner bag 2 filled with the liquid in advance by the conveyor 19 arranged on the upstream side of the chute 4 has a pouring spout 2a located at the upper surface (upper position) and the conveying direction (reference numeral 20 in FIG. 1). In the state of being arranged at the rear center position, it is conveyed to the inlet opening 6 of the chute 4 and stopped for a predetermined time. This transport and stop operation can be performed before the chute 4 is moved downward, during the chute 4 is moved downward, or after the chute 4 is moved downward. As the most desirable mode, it is preferable that the stop time elapses at the latest after the descent movement of the chute 4 is completed so that the next dropping operation can be performed immediately after the descent movement of the chute 4 is completed. . The predetermined stop time is a time during which the movement of the liquid in the inner bag 2 can be stabilized and the posture of the inner bag 2 can be stabilized.

As described above, when the pillow-type inner bag 2 preliminarily filled with the liquid is stopped in the vicinity of the inlet opening 6 of the chute 4 to stabilize the posture of the inner bag 2, the speed of the conveyor 19 is then increased. Is operated at a speed lower than the conveyance speed, and the pillow-type inner bag 2 filled with the liquid in advance is slowly advanced toward the inlet opening 6 and slowly enters the chute 4 from the inlet opening 6. . By this operation, the pillow-type inner bag 2 filled with the liquid falls in the chute 4 toward the outer box 3 located below the chute 4 by its own weight.

This drop operation will be described more specifically. First, a pillow-type inner bag 2 filled with a liquid has a front portion in the conveyance direction (indicated by an arrow 20 in FIG. 1) in the chute 5 from the inlet opening 6. The spout 2a comes into contact with the inner surface of the upper surface 4a (more specifically, in the vicinity of the center line 8 above the inner surface of the upper surface 4a) immediately before falling into its own weight and then the spout 2a From this contact state, the inner bag 2 falls from the inlet opening 6 to the outlet opening 7 by sliding the concave groove toward the outer box 3 while being guided by the concave groove along the center line 8. .

Since the chute 4 is disposed so as to be inclined with respect to the conveying direction of the pillow-type inner bag 2 (the arrow direction indicated by reference numeral 20 in FIG. 1), the chute is disposed substantially orthogonal to the conveying direction. Compared with the conventional apparatus, the posture of the inner bag 2 can be stabilized and dropped.

Further, the spout 2a is guided by the concave groove, whereby the inner bag 2 is dropped toward a desired position in the outer box, and the spout 2a can be arranged at a desired position with respect to the take-out area. it can. Further, the depression of the concave groove can prevent damage to the inner bag due to the spout 2a protruding from the outer surface of the upper surface of the inner bag 2, damage to the inner bag, and perforation.

Furthermore, the lower surface 4b of the main body 5 is arranged so as to be parallel to the upper surface 4a, and the distance (distance) from the position of the center line 8 of the inner surface of the upper surface 4a to the lower surface 4b is conveyed to the inlet opening 6. This corresponds to the dimension from the bottom surface of the inner bag to the upper surface of the spout 2a in the direction orthogonal to the conveying direction of the pillow-type inner bag 2 filled with the liquid to be filled (width dimension indicated by reference numeral 21 in FIG. 1). Accordingly, an extra space (gap) can be prevented from being provided, and therefore, the inner bag in the direction of the distance (distance) from the position of the center line 8 on the inner surface of the upper surface 4a to the lower surface 4b. There is no shake of 2 and it can be dropped stably.

Furthermore, since the outlet opening 7 is formed in an opening smaller than the inlet opening 6 and has, for example, a width dimension of about 90% of the width of the outer box 3, the inside of the main body 5 of the chute 4 is formed. Since the left side surface 4c and the right side surface 4d are narrowed down so as to taper downward, the direction perpendicular to the interval (distance) direction from the position of the center line 8 of the inner surface of the upper surface 4a to the lower surface 4b That is, the inner bag 2 is not shaken in the direction orthogonal to the paper surface in FIG. 1 and can be stably dropped.

Accordingly, the inner bag 2 can be dropped while the posture of the inner bag 2 is stabilized by the inclined arrangement of the chute, and the distance (distance) direction from the position of the center line 8 of the inner surface of the upper surface 4a to the lower surface 4b and the inner surface of the upper surface 4a The inner bag 2 can be stably dropped without shaking in both directions in the direction orthogonal to the distance (distance) direction from the position of the center line 8 to the lower surface 4b. Further, the spout 2a is connected to the center line. The inner bag 2 can be dropped by its own weight from the inlet opening 6 to the outlet opening 7 by sliding the concave groove toward the outer box 3 while being guided by the concave groove along the line 8. The spout 2a is accurately placed at a desired position with respect to the take-out area while preventing damage to the inner bag, such as pressure on the inner bag, breakage of the inner bag, and perforation. Can be stored accurately in position. That. Further, since the conventional components such as the suction means are not required, the configuration of the entire apparatus can be simplified and reduced in size, and the cost of the entire apparatus can be reduced.

As described above, the pillow-type inner bag 2 filled with the liquid is dropped by its own weight toward the outer box 3 located below the chute 4, and the inner bag 2 is dropped. 1 is accurately stored in the desired position in the outer box 3, the chute 4 moves upward from the position indicated by the solid line in FIG. 1 to the position indicated by the broken line in FIG. 22 is returned to a horizontal state with respect to the installation surface 30 of the pillow type back-in-box manufacturing apparatus 1 in a state where the outer case 3 in which the pillow-type inner bag 2 filled with the liquid is placed is placed. Then, it is moved to the next step (for example, inspection of the position of the inner bag 2 in the outer box 3 or blocking of the storage port 9 by a flap) by a transfer conveyor (not shown).

Further, as shown in FIG. 1, by setting the roller near the inlet opening 6 of the conveyor 19 to a roller having a smaller diameter, the sinking between the rollers of the pillow-type inner bag 2 filled with the liquid is suppressed. In addition, the dropping operation of the pillow-type inner bag 2 filled with the liquid can be performed more stably. Further, as shown in FIG. 1, the small-diameter roller group can be disposed so as to be inclined with respect to the other large-diameter roller group and the chute 4. By doing so, the dropping operation of the pillow type inner bag 2 filled with the liquid can be further stabilized.

Further, the upper surface 4 a of the main body 5 can be bent along the center line 8, and a bent portion can be formed by a line targeting the center line 8. 2 has not only the center line 8 but also a line 24 extending from the inlet opening 6 to the outlet opening 7 in a symmetrical and inclined manner with respect to the center line 8. Moreover, these bending may be rounded and bent in circular arc shape.

In the embodiments described so far, the line 8 extending from the inlet opening 6 to the outlet opening 7 on the upper surface 4a of the main body 5 is formed at the center position (the center position in the left-right direction) of the upper surface 4a of the main body 5. The line 8 extending from the inlet opening 6 to the outlet opening 7 on the upper surface 4a of the main body 5 can be a line formed at a position shifted from the central position of the upper surface 4a of the main body 5. . As can be understood from the above description, the line 8 extending from the inlet opening 6 to the outlet opening 7 on the upper surface 4a of the main body 5 indicates the position of the spout 2a of the pillow-type inner bag 2 and the main body 5. The concave grooves formed along the line 8 extending from the inlet opening 6 to the outlet opening 7 on the upper surface 4a are provided so as to correspond to each other. Therefore, as in the embodiment described so far, when the position of the spout 2a of the pillow-type inner bag 2 is in the state of being located at the position of the upper surface 4a and the rear center position in the transport direction, A line 8 extending from the inlet opening 6 to the outlet opening 7 on the upper surface 4 a of the main body 5 can be a center line formed at the center position of the upper surface 4 a of the main body 5. On the other hand, when the position of the spout 3a of the pillow type inner bag 2 is located at a position shifted from the position of the upper surface 4a and the rear center position in the transport direction, the upper surface 4a of the main body 5 is placed on the upper surface 4a. The line 8 extending from the opening 6 to the outlet opening 7 can be a line formed at a position shifted from the center position of the upper surface 4 a of the main body 5. 3 (a) and 3 (c), the position of the spout 2a of the pillow-type inner bag 2 is the position of the upper surface 4a and the rear in the transport direction, as in the above-described embodiment described with reference to FIGS. In the state of being disposed at the center position, a line 8 formed as a center line formed at the center position of the upper surface 4a of the main body 5 is shown, while FIGS. 3B and 3D show Is a state in which the position of the spout 3a of the pillow-type inner bag 2 is arranged at a position shifted from the position of the upper surface 4a and the rear center position in the transport direction, from the center position of the upper surface 4a of the main body 5. A line 8 formed at a shifted position is shown.
