The packaging/accommodating device 1 is used to manufacture a so-called bag-in-box 4 in which a flexible bag 2 as an inner bag is housed in an outer box 3. The packaging/accommodating device 1 is a packaging device that pillow-packs the flexible bag 2 with an exterior material 5 when the flexible bag 2 is accommodated in the exterior box 3 .

The shooter 10 integrally includes a guide tube 11 and an input port 12 continuous to one end side of the guide tube 11. Further, the shooter 10 is provided with a position sensor 13 that detects position information of the flexible bag 2.

The guide cylinder 11 is configured, for example, in a cylindrical shape that extends in the vertical direction with the axial direction being the vertical direction, and forms a passage portion 11a along the axial direction. For example, the passage portion 11a is vertically arranged in the vertical direction so that the upper side is the primary side and the lower side is the secondary side. The passage portion 11a is configured to allow the flexible bag 2 filled with contents to pass therethrough. For example, the opening of the lower end side of the guide tube 11, which is the secondary side, is arranged directly above the opening of the exterior box 3. The guide cylinder 11 has an opening at the lower end that corresponds to the opening at the upper part of the outer box 3 and is smaller than the opening of the outer box 3 . As an example, the guide tube 11 is configured to have a rectangular square tube shape corresponding to the rectangular exterior box 3, but the guide tube 11 is not limited to this. Further, the opening of the guide tube 11 is configured to be smaller than the opening of the exterior material 5 when the exterior material 5 is configured in a cylindrical shape. The guide cylinder 11 is supplied from the input port 12 and guides the flexible bag 2 to the upper opening of the outer box 3 while shaping it when the flexible bag 2 is lowered by gravity.

The input port 12 is continuously and integrally provided at the upper end portion of the guide tube 11 . The input port 12 is configured in a conical shape whose upper side, which is the primary side, expands. The input port 12 guides the flexible bag 2 inserted from the upper side, which is the primary side, to the guide cylinder 11, which is continuous to the lower side, which is the secondary side.

The position sensor 13 is provided, for example, at the input port 12, detects passage of the flexible bag 2, and sends detection data to the control unit 70.

A box standby section R1 is formed on the secondary side of the passage section 11a. The box standby section R1 is a space in which the outer box 3 can be placed. The box standby portion R1 is formed, for example, directly below the lower end portion of the guide cylinder 11.

The flexible bag 2 is formed into a bag shape by welding and sealing the four edges of a rectangular film. A filling port 2a called a spout is provided at a predetermined location of the flexible bag 2 and is made of synthetic resin and has a cylindrical shape. For example, the inside of the flexible bag 2 is filled with contents such as liquid through the filling port 2a. A male thread is formed on the outer periphery of the axial tip of the filling port 2a, and a removable cap made of synthetic resin is attached thereto.

The exterior material supply section 20 includes a sheet holding section 21 that holds the exterior material 5 and a sheet conveyance section 22 that conveys the exterior material 5.

The exterior material 5 is a plastic film and is configured in the form of a sheet having a predetermined width. For example, the exterior material 5 is made of low density polyethylene and has a thickness of 0.050 mm to 0.075 mm. For example, the width dimension of the exterior material 5 is configured to be larger than the circumferential dimension of the outer periphery of the guide tube 11 of the shooter 10.

The sheet holding section 21 has, for example, a holding shaft 21a extending in the horizontal direction, and holds the exterior material 5 wound around the outer periphery of the holding shaft 21a in a roll shape. The sheet holding section 21 is provided, for example, on one side of the shooter 10. As an example, the sheet holding section 21 is provided on the outer periphery of the shooter 10 on the opposite side to the bonding position Pa where both side edges of the exterior material 5 are joined by welding by the bag making section 30.

The sheet conveyance section 22 supplies the sheet-like exterior material 5 to the outer circumference of the passage section 11a. For example, the sheet conveyance section 22 unwinds the exterior material 5 from the sheet holding section 21 and aligns both side edges of the exterior material 5 along the outer periphery of the guide tube 11 while pasting the exterior material 5 on the side opposite to the sheet holding section 21. Continuously send toward position Pa.

As a specific example, the sheet conveyance section 22 includes a pair of rollers 22a, which serve as a pair of feeding members, provided on the outer periphery of the guide cylinder 11, for example. The pair of rollers 22a are provided on both sides of the bonding position Pa located on the opposite side of the holding shaft 21a of the sheet holding section 21 in the outer peripheral portion of the guide cylinder 11.

The pair of rollers is in contact with both edges of the exterior material 5 in the width direction, and the rotational action sends both edges of the sheet-like exterior material 5 toward the bonding position Pa from both sides. For example, the bonding position Pa is a position on the outer periphery of the guide tube 11 that faces the center of the sheet holding section 21 in the width direction on the opposite side with the guide tube 11 in between, and the sheet conveyance section 22 From the holding part 21, both side edges of the sheathing material 5 are brought together by wrapping them half a circumference along the outer peripheral surface of the guide cylinder 11 and sending them toward the bonding position Pa. The exterior material 5 is formed into a cylindrical shape that follows the outer circumference of the guide tube 11.

The bag making section 30 includes a first welding mechanism 31 , a second welding mechanism 32 , a separation mechanism 33 , and an opening/closing mechanism 34 . The bag making section 30 configures a bag-shaped storage section 5A by welding and closing a predetermined portion of the exterior material 5 disposed in a cylindrical shape on the outer circumference of the guide tube 11, and the exterior material 5 is placed in the housing section 5A. Cut each time. In this embodiment, the welding mechanism 32 and the separation mechanism 33 are provided integrally and are supported by, for example, a common opening/closing mechanism 34.

The first welding mechanism 31 is a heat seal that joins the outer periphery of the guide tube 11 at a bonding position Pa along the longitudinal direction along the feeding direction with both side edges of the sheathing material 5 butted and overlapped by heat welding. It is a device. The first welding mechanism 31 has a welding head that heats the exterior material 5 by operating in contact with or in close proximity to the exterior material 5 . The first welding mechanism 31 overlaps and welds both side edges of the continuously fed exterior material 5 at a predetermined timing, thereby forming a first welded portion 5a continuous in the vertical direction. The first welding part 5a may be formed by so-called envelope pasting, in which both side edges of the exterior material 5 are overlapped and pasted together, or as so-called gassho pasting, in which the inner surfaces of both side edges of the sheath material 5 are made to face each other and are heat-sealed and pasted together. Good too.

The second welding mechanism 32 is configured to heat weld the cylindrical exterior material 5 at a predetermined position on the secondary side of the outlet of the guide cylinder 11 in a horizontal direction perpendicular to or intersecting the vertical direction, which is the feeding direction. It is a sealing device. The second welding mechanism 32 includes a pair of welding heads. The pair of welding heads are provided in the opening/closing mechanism 34 and are configured to be able to approach and separate from each other by the opening/closing operation of the opening/closing mechanism 34. The pair of welding heads heats the exterior material 5 while sandwiching the exterior material 5 when the opening/closing mechanism 34 is in the closed state, thereby welding the ends of the region constituting the housing portion 5A.
As a specific example, the second welding mechanism 32 forms two second welding parts 5b and 5c, upper and lower, with the cutting position in between. The second welded portion 5b located above the cutting position constitutes the bottom of the accommodating portion 5A disposed above when separated. The second welded portion 5c located below the cutting position constitutes the ceiling portion of the accommodating portion 5A formed below when separated. That is, in each accommodating portion 5A, the second welded portion 5b constitutes the bottom portion, and the second welded portion 5c constitutes the ceiling portion.

The separation mechanism 33 is provided on the secondary side of the passage section 11a, that is, below the passage section 11a. The separation mechanism 33 separates the sheathing material 5 vertically by cutting the sheathing material 5 along the lateral direction at a cutting position between the second welding parts 5b and 5c, for example. The exterior material 5 is divided into 5A units. The separation mechanism 33 includes, for example, a pair of cutter blades extending laterally. The cutter blades are provided in the opening/closing mechanism 34 and are configured to be able to approach and separate from each other by the opening/closing operation of the opening/closing mechanism 34. The separation mechanism 33 cuts the exterior material 5 along the lateral direction at a cutting position on the secondary side of the passage portion 11a by closing the pair of cutter blades under the control of the control unit 70.

The opening/closing mechanism 34 supports the welding head of the second welding mechanism 32 and the cutter blade of the separation mechanism 33, and opens and closes the welding mechanisms 31, 32 and the separation mechanism 33 by an opening/closing operation.

The exterior box 3 is a rectangular housing made of, for example, cardboard, and includes a case part 3a having a rectangular parallelepiped storage space with an opening at the top, and a plurality of housings provided continuously around the periphery of the opening at the top of the case part 3a. It has a lid part 3b integrally. The exterior box 3 is placed in the box standby section R1 with the lid section 3b open and the opening of the case section 3a facing upward, which is the packaging position. Note that the exterior box 3 is not limited to a cardboard housing, and may have other configurations. For example, a plastic container such as a resin crate having an opening at the top may be used as the exterior box 3.

The box supply unit 50 includes a box table 51 including a plurality of conveyance rollers 51a as feeding members, and a drive source such as a motor that rotates the plurality of conveyance rollers 51a. The box table 51 supports the outer box 3 in a box standby section R1 set below the cutting position with its top open. Further, the drive source sequentially moves the outer box 3 at a predetermined takt time along the box path passing through the box standby section R1 by rotating the conveyance roller.

The control unit 70 includes a processor and a memory including RAM and ROM. The control section 70 controls the operation of each section of the packaging/accommodating device 1 by executing a predetermined program according to a preset program and various conditions. For example, the control unit 70 controls the operation of each part, and performs an exterior material supply process, a bag making process, a box supply process, and a bag storage process continuously or intermittently at predetermined processing timing. Have them do it repeatedly. For example, the control unit 70 sends the bag row 2A and the exterior material 5 at a predetermined speed, sequentially sends the exterior boxes 3 at a predetermined takt time, and controls the bag row 2A and the exterior material 5 for each takt time. Repeat bag processing. For example, the takt time is set to about 6 seconds or 8 seconds. Further, as an example, the control unit 70 may control the timing of various processes based on the position information of the flexible bag 2 detected by the position sensor 13 provided in the input port 12.

The packaging method according to this embodiment will be described below. The packaging method according to this embodiment includes an exterior material supply process, a bag making process, a box supply process, and a bag accommodation process.

As the packaging material supply process, the control unit 70 supplies the sheet-like packaging material 5 along the outer periphery of the passage section 11a through which the flexible bag 2 passes. As a specific example, the control unit 70 rotates the pair of rollers 22a of the sheet conveyance unit 22 of the packaging material supply unit 20, so that the packaging material 5 wound in a roll around the holding shaft 21a in the sheet holding unit 21 is rolled. Take it out, wrap it around the guide cylinder 11, and send it. By this feeding operation of the roller 22a, the sheathing material 5 is arranged in a cylindrical shape on the outer circumference of the guide tube 11 and is fed downstream. As an example, the control unit 70 unwinds and sends the exterior material 5 by a distance corresponding to one storage section 5A at every predetermined takt time.

As part of the bag making process, the control unit 70 drives the welding mechanisms 31 and 32 at predetermined timing to weld predetermined locations on the exterior material 5 to form the housing sections 5A, and for each housing section 5A, the exterior material 5 cut. As a specific example, the control unit 70 first drives the first welding mechanism 31 and the second welding mechanism 32 to weld the exterior material 5 at the first welding part 5a and the second welding part 5b, and then the flexible bag 2 An accommodating portion 5A having an accommodating portion in which is accommodated is formed. Furthermore, the control unit 70 cuts the exterior material 5 by driving the separation mechanism 33 at a predetermined timing. Here, the welding mechanisms 31, 32 and the separation mechanism 33 are provided integrally, and are supported by, for example, a common opening/closing mechanism 34, and the welding mechanisms 31, 32 and the separation mechanism 33 are connected by the opening/closing operation of the opening/closing mechanism 34. open and close in sync.

In the bag making process, the first welding mechanism 31 stacks both side edges of the sheet-like exterior material 5 disposed in a cylindrical shape on the outer periphery of the passage portion 11a and welds them in the vertical direction, thereby forming the cylindrical exterior material 5. Close the pasted parts on the sides. In addition, the second welding mechanism 32 stacks the exterior materials 5 on the secondary side of the passage section 11a and welds them in two rows in the horizontal direction, thereby attaching the bottom part of the upper housing part 5A and the ceiling of the lower housing part 5A. Close the two parts. Further, the separation mechanism 33 moves the cutter blade toward and away from the exterior material 5 through an opening/closing operation, thereby cutting the exterior material 5 into each accommodating portion 5A, for example, at a cutting position provided in the second welded portion 5b.

The control unit 70 may manage the timing of welding and cutting in the bag making process based on the position information of the flexible bag 2 detected by the position sensor 13. For example, by controlling each process to be performed after a predetermined period of time has elapsed after passing through the input port 12, it becomes possible to perform processes corresponding to the position of the flexible bag 2.

As the box supply process, the control section 70 rotates the plurality of conveyance rollers 51a of the box supply section 50 at a predetermined timing so that the box conveyance path passing through the box standby section R1 on the secondary side of the shooter 10 is carried out. , transports the outer boxes 3, and sequentially supplies the outer boxes 3 to the box standby section R1.

As bag storage processing, the control unit 70 sequentially supplies the flexible bags 2 to the input port 12 of the shooter 10 at a predetermined timing. In this embodiment, since the chute 10 is arranged in the vertical direction, the flexible bag 2 inserted into the chute 12 descends due to its own weight and is guided by the guide tube 11 of the chute 10. At this time, since the bottom formed by the second welded part 5c is located below the lower end of the guide tube 11, which is the secondary side of the guide tube 11, the flexible bag 2 is lowered. When being sent to the secondary side of the shooter 10, it is accommodated in the bottom of the accommodating portion 5A of the exterior material 5, which is closed like a bag by welding. Then, due to the weight of the flexible bag 2 and the operation of supplying the exterior material 5, the storage section 5A of the flexible bag 2 and the exterior material 5 that accommodates it is lowered, and the upper opening of the exterior box 3 waiting in the box standby section R1 below is lowered. It falls inside and is contained.

That is, while the flexible bag 2 inserted into the input port 12 falls from the input port 12 through the guide cylinder 11, the exterior material 5 is made into a bag, wrapped by the storage section 5A, and then input into the exterior box 3. be done.

Then, with the storage section 5A placed inside the box or above the opening of the exterior box 3, the second welding mechanism 32 causes the second welding section 5b to Weld 5c. By welding the second welding parts 5b and 5c, the ceiling of the accommodating part 5A in the exterior box 3 and the bottom of the upper exterior material 5 are closed. Then, the separation mechanism 33 cuts the exterior material 5 along a line along the lateral direction at a cutting position between the two second welded parts 5b and 5c, thereby separating the upper and lower housing parts 5A.

According to the packaging storage device 1 and the packaging method according to this embodiment, the processing efficiency of packaging processing can be improved with a simple configuration. That is, by forming the exterior material 5 into a bag when the flexible bag 2 is housed in a box, packaging of the flexible bag 2 using the exterior material 5 can be realized. That is, the packaging process can be achieved by simply forming the packaging material into a bag during the box-packing process of putting the flexible bag 2 into the packaging box 3, resulting in good processing efficiency.

Moreover, it is only necessary to add a mechanism for supplying and welding the exterior material 5 to the shooter 10 to the housing device for putting the flexible bag 2 into the exterior box 3, thereby simplifying the device configuration. For example, compared to the method of manually placing a flexible bag in a plastic bag and tying the opening of the bag, or the method of attaching a bag member to the inner surface of an outer box in advance, the processing time is shorter and the work can be simplified. By wrapping the flexible bag 2 with the exterior material 5, it is possible to prevent dirt and insects from getting in and damage, for example, when the flexible bag 2 is removed from the exterior box 3 and handled, or when it is handled in another container such as a resin crate. be able to. Therefore, it is possible to improve handling properties and take measures against pinholes.

Further, according to the packaging storage device 1 according to the above embodiment, the guide tube 11 of the chute 10 is formed into a rectangular tube shape corresponding to the opening of the outer box 3, so that when the flexible bag 2 passes through the passage section, The flexible bag 2 can be shaped into a shape that can be easily inserted into the opening of the outer box 3. Further, the chute 10 makes it easy to maintain the posture of the flexible bag 2, and for example, it becomes possible to store the flexible bag 2 in the exterior box 3 with the filling port 2a facing upward.

In addition, in the packaging/accommodating device 1 according to the above embodiment, the tube made of the exterior material 5 is larger than the guide tube 11, and a gap is formed between the guide tube 11 and the exterior material 5. Since air can escape easily and the gap serves as an air cushion, the exterior material 5 is less likely to be damaged.
