Description

[Technical field]

[0001] The present invention relates to a packing device and a packing method, and more particularly to a packing device and a packing method for packing articles inside a box. [Background technology]

[0002] 2. Description of the Related Art Conventionally, in a box packing device for inserting articles into an open box, a guide member is known that holds a flap in an open state in order to smoothly insert the articles into the box.

[0003] For example, in the boxing device of Patent Document 1, a guide member is used to push open the flaps of a box, and in this state, an article such as a bottle is inserted into the box. This prevents the bottle from getting caught on the tip of the flap and falling over when the article is inserted into the box. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2000-326917 A Summary of the Invention [Problem to be solved by the invention]

[0005] Generally, a box such as an A-type corrugated cardboard box is formed from a single sheet and includes four side walls that form the sides of the box, flaps provided at the open ends of each side wall, and bonding parts that extend from the circumferential ends of the side walls and connect the side walls together. When the box is assembled, the bonding parts are provided on the inner surfaces of the box.

[0006] However, in the packing device of Patent Document 1, the guide member holds only the extended end of the flap, so when inserting an item into the box, there was a risk that the item would get caught on the bonded portion and the box would be crushed.

[0007] The present invention has been made in consideration of the above-mentioned problems, and an object of the present invention is to provide a packing device and a packing method that can suppress interference between a box body and an article when inserting an article into the box body, thereby enabling smooth insertion. [Means for solving the problem]

[0008] The above problem is solved by a packing device of the present invention, which packs articles into a box body, and includes a guide member that guides the article inserted into the box body by opening flaps of the box body, a switching member that switches the state of the guide member, and an insertion member that inserts the article into the box body, and the guide members are provided so as to abut against a pair of flaps provided on both side surfaces of the box body from the inside of the box body, respectively, and include a first holding portion and a second holding portion that hold the flaps in an open state, and an insertion member that extends from the first holding portion and and an extension portion that covers the adhesive portion provided on the inner surface of the box from the inside of the box, and the first holding portion and the second holding portion are switched by the switching member between an open state in which the flap is opened and held, and a closed state in which the flap is closer to each other than in the open state, and the switching member rotates the first holding portion and the second holding portion, respectively, to switch the guide member between the open state and the closed state, and the insertion member inserts the article into the inside of the box when the guide member is in the open state. With the above-mentioned configuration, the holding part can be rotated to stably hold the flap while the extension part can cover the bonding part. Therefore, when inserting an article into the box, the guide member can suppress interference between the flap and the bonding part and the article, allowing the article to be inserted smoothly.

[0009] In this case, when the first retaining portion and the second retaining portion are switched to the open state, the extension portion covers the open side end of the bonding portion, and the tip portion of the extension portion is positioned at a position overlapping the open side end of the bonding portion, and when the first retaining portion and the second retaining portion are switched to the closed state, the switching member passes the extension portion forward of the article inserted into the box body in the article insertion direction. With the above configuration, when the guide member is rotated to open or close the flap, the guide member can be prevented from coming into contact with an article, which can result in the article being scratched or deformed.

[0010] At this time, the first retaining portion and the second retaining portion are switched by the switching member between the open state in which they are positioned parallel to each other, and the closed state in which they are positioned intersecting each other, and it is preferable that a cutout portion be formed in the first retaining portion so that the second retaining portion can fit into it in the closed state. With the above-described configuration, the formation of the notches allows the holding portions to be switched to a closed state in which they cross each other, thereby making it possible to reduce the space required by the guide member in the closed state.

[0011] In this case, the extending portion may be provided only on the first retaining portion out of the first retaining portion and the second retaining portion. With the above-mentioned configuration, the extension portion is provided only on the first holding portion in correspondence with the position of the bonding portion of the box body, so that the guide member can be configured compactly. In addition, the number of components of the guide member can be reduced, so that the manufacturing cost of the packing device can be reduced.

[0012] In this case, the extending portion may have a guide surface for guiding the article into the box, and the guide surface may be inclined toward the bonding portion. With the above-described configuration, when the guide member is rotated to open or close the flap, it is possible to further prevent the guide member from coming into contact with an article and causing damage or deformation to the article.

[0013] In this case, the guide member is arranged to abut against a second flap adjacent to the flap from the inside of the box body, and has a third retaining portion that holds the flap in an open state, and the third retaining portion may extend from the first retaining portion or the second retaining portion. With the above-mentioned configuration, flaps other than the flaps provided on both sides of the box can also be held. Therefore, when inserting an article into the box, the guide member can further reduce interference between the flaps and the article, allowing for smooth insertion.

[0014] The above problem is solved by a packing method using a packing device of the present invention, which packs the article into a box body using a packing device, and includes a box body preparation step of preparing the box body, a guide member placement step of placing the guide member inside the box body using the switching member, an insertion step of inserting the article into the box body, and a detachment step of detaching the guide member from the box body, wherein in the guide member placement step, the guide member switched to the open state holds the flap in an open state from inside the box body and covers the bonded portion from inside the box body, and in the detachment step, when the guide member is switched to the closed state, the extension portion passes before the article inserted into the box body in the insertion direction of the article. With the above-mentioned configuration, an article can be inserted into the box while the extension portion covers the bonding portion. Therefore, the guide member can further suppress interference between the flap and the bonding portion and the article, allowing for smooth insertion. Furthermore, when the guide member is rotated to open and close the flap, the guide member can be prevented from coming into contact with the article, which can cause the article to be scratched or deformed. Effect of the Invention

[0015] According to the packing device and packing method of the present invention, when an article is inserted into a box, the guide member prevents interference between the flap and the bonding portion and the article, allowing the article to be inserted smoothly.

[0017] Hereinafter, an embodiment of the present invention will be described with reference to FIGS. This embodiment relates to a packing device that packs items inside a box body, and that, when inserting an item into the box body, uses a guide member to suppress interference between the flap and the bonding portion and the item, thereby enabling smooth insertion.

[0018] In the following description, the "up-down direction" refers to the up-down direction when inserting an item into the box as shown in FIG. 1. Additionally, the "front-to-back direction" refers to the insertion direction in which an item is inserted into the box. The direction in which an item is inserted into the box is referred to as the "front direction". Additionally, the "left-to-right direction" is a direction perpendicular to the "up-down direction" and the "front-to-back direction". Additionally, when facing the forward direction in which an item is inserted, the right side is referred to as the "right direction" and the left side is referred to as the "left direction".

[0019] <Packing equipment> The packing device 1 of this embodiment is for packing an article S into a box body B from an opening of the box body B. Specifically, the packing device 1 inserts the article S into the box body B from the side in a state in which the box body B is arranged so that the opening of the box body B faces sideways. 1 and 2, the packing device 1 includes a base member 2, a guide member 3 that guides an article S to be inserted into a box body B, a switching member 4 that switches the state of the guide member 3, an insertion member 5 that inserts the article S into the box body B, and a controller 6 (control unit) that is provided on the base member 2 and controls the switching member 4 and the insertion member 5. The packing device 1 guides the article S by the guide member 3 that is arranged inside the box body B, and inserts the article S from the side into the box body B by the insertion member 5. Note that the packing device 1 may also be a device that inserts the article S from above into a box body B that is arranged with its opening facing upward.

[0020] Here, the box B and the item S will be described. Box B is, for example, a type A corrugated cardboard box, as shown in Fig. 3. Box B is formed from a single sheet and includes four side wall portions P constituting the side surfaces of box B, flaps F provided at the open ends of each side wall portion P, and bonding portions G extending from the circumferential ends of the side wall portions P and connecting the side wall portions P together. When box B is assembled, bonding portions G are provided on the inner surfaces of box B.

[0021] The side wall portion P is composed of a right wall portion P1 and a left wall portion P2 which form both side surfaces of the box body B, an upper wall portion P3 which forms the ceiling surface of the box body B, and a lower wall portion P4 which forms the bottom surface of the box body B. The flaps F include a right flap F1 provided on the right wall portion P1, a left flap F2 provided on the left wall portion P2, an upper flap F3 (corresponding to a second flap) provided on the upper wall portion P3, and a lower flap F4 provided on the lower wall portion P4. The right flap F1 and the left flap F2 are a pair of flaps F provided on both side surfaces of the box body B. The bonding portion G is a glue joint portion extending from the right end portion of the lower wall portion P4, and is overlapped and bonded to the inside of the right wall portion P1.

[0022] The article S is a container such as a paper pack, and contains a liquid inside. The article S is stored inside the box B in a state where a plurality of the articles S are stacked in multiple layers separated by partitions or the like. The number of items S stored inside the box B is not limited to multiple items, but may be one. The item S is not limited to paper cartons, but may be bottles, cans, or bottles. Furthermore, the item S is not limited to containers, and may be anything that can be packed into a box.

[0023] <Base material> As shown in Figures 1, 2 and 4, the base member 2 has a platform 2a on which an item S is placed, a guide portion 2b that guides the item S placed on the platform 2a, an attachment portion 2c for attaching the guide member 3, a support shaft 2d that rotatably supports the guide member 3, and a connection portion 2e that connects to the guide member 3.

[0024] 1, 2, and 4, the mounting table 2a is a long plate-like member extending in the front-rear direction. When the article S is inserted into the box body B, the article S slides forward on the upper surface of the mounting table 2a and is inserted into the box body B. The bottom flap F4 of the box B is disposed below the placement table 2a. In other words, the placement table 2a holds the bottom flap F4 in an open state. This prevents the article S from getting caught on the bottom flap F4 when the article S is inserted, and allows the article S to be smoothly inserted into the box B.

[0025] The guide portions 2b are provided at positions sandwiching the placement table 2a from the sides thereof, and guide both sides of the article S placed on the placement table 2a. The mounting portion 2c is for rotatably mounting the guide member 3, and is provided in pair at an outer position of the guide portion 2b. A support shaft 2d is attached to each tip of the mounting portion 2c.

[0026] As shown in FIGS. 1 and 2, the support shaft 2d is a shaft member that extends in the vertical direction and supports the guide member 3 so that it can rotate. The connection part 2e is attached to the support shaft 2d, and connects the support shaft 2d and the guide member 3. When the connection part 2e is moved by the switching member 4, the guide member 3 rotates about the support shaft 2d.

[0027] <Guide parts> The guide member 3 is for opening the flap F of the box body B and guiding the article S to be inserted into the box body B. As shown in Figs. 1, 2 and 4, the guide member 3 has a first holding part 10 for holding the right flap F1 in an open state, a second holding part 20 for holding the left flap F2 in an open state, a third holding part 30 for holding the upper flap F3 in an open state, and an extending part 40 for covering the bonding part G from the inside of the box body B.

[0028] The first holding portion 10 and the second holding portion 20 of the guide member 3 are arranged to abut against a pair of flaps F provided on both side surfaces of the box body B from the inside of the box body B, and hold the flaps F in an open state.

[0029] The first holding portion 10 and the second holding portion 20 are switched by the switching member 4 between an open state (FIG. 2) in which the flap F is opened and held, and a closed state (FIG. 1) in which the first holding portion 10 and the second holding portion 20 are closer to each other than in the open state. The open state is a state in which the first holding part 10 and the second holding part 20 are positioned parallel to each other. The closed state is a state in which the first holding part 10 and the second holding part 20 are positioned crossing each other (forming an X-shape when viewed from above).

[0030] The first holding part 10 is rotated rightward about the support shaft 2d by the switching member 4 from the closed state shown in Fig. 1 to the open state shown in Fig. 2. In the open state, the first holding part 10 holds the right flap F1 in an open state as shown in Fig. 2. The first holding part 10 is a metal plate-like member that extends in the front-rear direction in the open state and has a concave shape with a concave front side. The first retaining portion 10 has a first main body portion 11, a notch portion 12 formed in the first main body portion 11, an upper engagement portion 13 that engages with an upper portion of the second retaining portion 20, and a lower engagement portion 14 that engages with a lower portion of the second retaining portion 20.

[0031] The first main body portion 11 guides the article S to be inserted into the box body B. Specifically, when the article S is inserted into the box body B, the first main body portion 11 guides the right side of the article S moving on the upper surface of the placement table 2a. A connection part 2e is attached to the rear end part of the first main body part 11. When the connection part 2e is moved by the switching member 4, the first main body part 11 rotates relative to the base member 2 about the support shaft 2d.

[0032] 1, the cutout portion 12 is a recess into which the second holding portion 20 fits in the closed state. In other words, the cutout portion 12 is a locked portion with which a protrusion 22 of the second holding portion 20, which will be described later, is locked. The cutout portion 12 is provided in a middle portion of the first main body portion 11 in the up-down direction.

[0033] 1, in the closed state, the upper engaging portion 13 enters into and engages with the second holding portion 20. In other words, the upper engaging portion 13 is an engaging portion that engages with an upper engaged portion 23 of the second holding portion 20, which will be described later.

[0034] 2 and 4, the upper engagement portion 13 holds the right flap F1 in the open state. This prevents the article S from getting caught on the right flap F1 when the article S is inserted, and allows the article S to be smoothly inserted into the box body B. The upper engagement portion 13 is provided on the upper portion of the first main body portion 11 and abuts against the inside of the upper portion of the right flap F1 to open the right flap F1. Note that the upper engagement portion 13 does not necessarily have to abut against the right flap F1 as long as it can hold the right flap F1 in the open state. In the open state, the upper engagement portion 13 extends forward from the first main body portion 11 and has a generally trapezoidal shape in a side view. The upper end of the upper engagement portion 13 slopes downward as it extends forward. This prevents the first holding portion 10 from getting caught on the upper flap F3, and allows the first holding portion 10 to be smoothly positioned inside the box body B (specifically, inside the flap F).

[0035] 1, the lower engaging portion 14 enters into and engages with the second holding portion 20 in the closed state. In other words, the lower engaging portion 14 is an engaging portion that engages with a lower engaged portion 24 of the second holding portion 20, which will be described later. The lower engaging portion 14 is provided on a lower portion of the first main body portion 11.

[0036] 2 and 4, the lower engagement part 14 holds the right flap F1 in an open state. The lower engagement part 14 abuts against the inside of the lower part of the right flap F1 to open the right flap F1. Note that the lower engagement part 14 does not necessarily have to abut against the right flap F1 as long as it can hold the right flap F1 in the open state. The lower engagement portion 14 extends forward from the first main body portion 11 in the open state, and has a generally inverted L-shape in side view. An extension portion 40 that covers the bonded portion G is provided on a front end portion 14a of the lower engagement portion 14.

[0037] The second holding part 20 is rotated leftward about the support shaft 2d by the switching member 4 from the closed state shown in Fig. 1 to the open state shown in Fig. 2. In the open state, the second holding part 20 holds the left flap F2 in an open state as shown in Fig. 2. The second holding part 20 is a metal plate-like member that extends in the front-rear direction in the open state and has a convex shape that protrudes forward. The second retaining portion 20 has a second main body portion 21, a protrusion 22 that fits into the cutout portion 12 of the first retaining portion 10, an upper engaged portion 23 that engages with the upper engaging portion 13 of the first retaining portion 10, and a lower engaged portion 24 that engages with the lower engaging portion 14 of the first retaining portion 10.

[0038] The second main body portion 21 guides the article S to be inserted into the box body B. Specifically, when the article S is inserted into the box body B, the second main body portion 21 guides the left side portion of the article S moving on the upper surface of the placement table 2a. A connection part 2e is attached to the rear end part of the second main body part 21. When the connection part 2e is moved by the switching member 4, the second main body part 21 rotates relative to the base member 2 about the support shaft 2d.

[0039] 1, the protrusion 22 is a convex portion for entering the first holding portion 10 in the closed state. In other words, the protrusion 22 is a locking portion that locks into the cutout portion 12 of the first holding portion 10. The protrusion 22 is provided in a middle portion of the second main body portion 21 in the up-down direction.

[0040] 2 and 4, the protrusion 22 holds the right flap F1 open in the open state. This prevents the article S from getting caught on the left flap F2 when the article S is inserted, and allows the article S to be smoothly inserted into the box body B. The protrusion 22 is provided in the middle part of the second main body part 21 and abuts against the inside of the middle part of the left flap F2 to open the left flap F2. Note that the protrusion 22 does not necessarily have to abut against the left flap F2 as long as it can hold the left flap F2 in the open state. The protrusion 22 extends forward from the second main body portion 21 in the open state, and has a generally rectangular shape in side view.

[0041] 1, the upper engaged portion 23 is a notch into which the first holding portion 10 fits in the closed state. In other words, the upper engaged portion 23 is an engaged portion that engages with the upper engaging portion 13 of the first holding portion 10. The upper engaged portion 23 is provided on the upper portion of the second main body portion 21.

[0042] 1, the lower engaged portion 24 is a notch into which the first retaining portion 10 fits in the closed state. In other words, the lower engaged portion 24 is an engaged portion that engages with the lower engaging portion 14 of the first retaining portion 10. The lower engaged portion 24 is provided on the lower portion of the second main body portion 21.

[0043] The guide member 3 has a fork shape in which the first holding portion 10 and the second holding portion 20 intersect and engage with each other. By providing the notch portion 12, the first holding portion 10 and the second holding portion 20 can be rotated to a position where they intersect with each other. Although the first holding portion 10 has the notch portion 12 in the middle in the up-down direction, the position and the number of the notch portion 12 are not limited thereto. The guide member 3 may have any shape as long as the first holding portion 10 and the second holding portion 20 intersect with each other and engage with each other.

[0044] 2 and 4, the third holding part 30 holds the upper flap F3 in an open state when the first holding part 10 is rotated by the switching member 4 to the open state. The third holding part 30 is a metal plate-like member having a rectangular shape that is elongated in the left-right direction in the open state. The third holding portion 30 is provided at the upper end of the upper engagement portion 13 and extends inward (leftward) from the upper end of the upper engagement portion 13. The third holding portion 30 abuts against the lower surface of the upper flap F3 to open the upper flap F3. Note that the third holding portion 30 does not necessarily have to abut against the upper flap F3 as long as it can hold the upper flap F3 in the open state.

[0045] 2 and 4, the third holding portion 30 is inclined downward as it moves forward along the first holding portion 10. This prevents the front end portion of the third holding portion 30 from getting caught on the upper flap F3, and allows the third holding portion 30 to be smoothly positioned inside the box body B (specifically, inside the flap F). The front end portion of the third holding portion 30 is provided at a position where it does not interfere with the article S.

[0046] 1, 2, and 4, the extension portion 40 extends from the lower engagement portion 14 of the first holding portion 10 and covers the bonding portion G provided on the inner surface of the box body B from the inside of the box body B. In other words, the extension portion 40 is a portion of the lower engagement portion 14 that covers the bonding portion G. The extension portion 40 is a plate-like member that is long in the front-rear direction and extends continuously from the lower engagement portion 14. In this embodiment, the extension portion 40 is formed integrally with the lower engagement portion 14, but the extension portion 40 may be a separate member.

[0047] 4, the extension portion 40 is formed to be longer than the upper engagement portion 13 of the first retaining portion 10. When the first retaining portion 10 is switched to the open state, the front end portion 13a of the upper engagement portion 13 and the front end portion 14a of the lower engagement portion 14 cover the connection end portion of the right flap F1. 5, when the first holding part 10 and the second holding part 20 are switched to the open state, the extending part 40 covers the opening side end G1 of the bonding part G. Specifically, the tip of the extending part 40 is disposed at a position overlapping the opening side end G1 of the bonding part G.

[0048] Since the bonding portion G is provided on the inner surface of the box body B, there is a risk that the article S may get caught on the bonding portion G when inserting the article S into the box body B. By arranging the extension portion 40 so as to cover the opening side end portion G1 of the bonding portion G, it is possible to prevent the article S from getting caught on the bonding portion G when inserting the article S into the box body B.

[0049] Furthermore, when the first holding portion 10 and the second holding portion 20 are switched to the closed state, the extension portion 40 passes in front of the article S inserted into the box B in the insertion direction of the article S (front-rear direction). If the extension part 40 is formed long, there is a risk that the extension part 40 will come into contact with the article S when the first holding part 10 is rotated by the switching member 4, causing damage or deformation to the article S. Therefore, by forming the extension part 40 short so that the tip of the extension part 40 is positioned to overlap the opening side end G1 as shown in Fig. 4, interference between the extension part 40 and the article S can be suppressed.

[0050] 6, the extension portion 40 has a guide surface 40a that guides the article S into the box body B. The guide surface 40a is inclined toward the bonding portion G. Therefore, when inserting the article S into the box body B, the article S can be smoothly inserted. In addition, when the first holding portion 10 and the second holding portion 20 are switched to the closed state, the guide surface 40a is inclined in a tapered shape, so that interference between the extension portion 40 and the article S can be further suppressed.

[0051] Moreover, the bonding portion G is provided only on the right wall portion P1 side of the box body B. Therefore, the extending portion 40 is provided only on the first holding portion 10, out of the first holding portion 10 and the second holding portion 20, in correspondence with the position of the bonding portion G. Since the extending portion 40 is provided only on the first holding portion 10 in correspondence with the position of the bonding portion G when the guide member 3 is in the open state, the guide member 3 can be configured compactly. Furthermore, since the number of components of the guide member 3 can be reduced, the manufacturing cost of the packing device 1 can be reduced. When the bonding portion G is provided on the left wall portion P2 side, the extending portion 40 may be provided on the second holding portion 20. Moreover, the extending portion 40 may be provided on both the first holding portion 10 and the second holding portion 20.

[0052] <Switching parts> 1 and 2, the switching member 4 rotates the first holding portion 10 and the second holding portion 20, respectively, to switch the guide member 3 between an open state and a closed state. The switching member 4 is a link mechanism, and is provided on the base member 2. A pair of switching members 4 are provided on the outer side of the guide portion 2b of the base member 2. In the following description, the configuration of the left switching member 4 will be described as an example.

[0053] The switching member 4 has a link portion 4a that is connected to the connection portion 2e, and a drive portion 4b for driving the link portion 4a. A tip end of the link portion 4a is connected to the connection portion 2e. A base end of the link portion 4a is connected to the drive portion 4b. The tip end and base end of the link portion 4a are rotatably connected to each other by a rotation shaft (not shown).

[0054] 2, when the driving part 4b moves backward, the base end of the link part 4a moves backward, and the tip part of the link part 4a rotates horizontally by the rotation shaft. When the tip part of the link part 4a rotates, the connection part 2e rotates leftward, and the second holding part 20 connected to the connection part 2e rotates about the support shaft 2d.

[0055] Before the article S is inserted, the switching member 4 rotates the first holding part 10 and the second holding part 20 to switch the guide member 3 to the open state. In this way, the extending part 40 can be smoothly positioned to cover the bonding part G, and positional deviation of the extending part 40 can be suppressed.

[0056] For example, when the extending portion 40 is moved straight forward and disposed inside the box body B, there is a risk that the extending portion 40 itself may get caught on the bonding portion G. Therefore, by rotating the first holding portion 10 and the second holding portion 20, it is possible to prevent the extending portion 40 from interfering with the bonding portion G. Furthermore, for example, when the guide member 3 in the closed state is moved straight forward and disposed inside the box body B, and then switched to the open state inside the box body B, multiple drive sources are required. Therefore, by rotating the first holding part 10 and the second holding part 20, the state of the guide member 3 can be switched with a simple configuration.

[0057] After the article S is inserted, the switching member 4 rotates the first holding portion 10 and the second holding portion 20 to switch the guide member 3 to the closed state. The switching member 4 passes the extension portion 40 in front of the article S inserted into the box body B in the insertion direction of the article S. This makes it possible to suppress interference between the extension portion 40 and the article S.

[0058] <Insertion Part> 4, the insertion member 5 is a pushing member for inserting the article S into the box body B. The insertion member 5 operates when the guide member 3 is opened by the switching member 4, and inserts the article S into the box body B. More specifically, the insertion member 5 abuts against the rear end of the article S placed on the placement table 2a, and pushes the article S into the box B so that it passes between the first holding portion 10 and the second holding portion 20.

[0059] <Controller> The controller 6 (control unit) is equipped with a CPU (processor) as a data arithmetic and control processing device, ROM and RAM as storage devices, and a communication interface for sending and receiving information data (RAM is not required). A packing process program is stored in the ROM and RAM, and the functions of the packing device 1 are realized by the CPU (processor) executing the program. Specifically, the control controller 6 is configured to perform the boxing process by receiving signals from an operation unit and a sensor (not shown) and transmitting control signals to the switching member 4 and the insertion member 5. In addition, the control controller 6 is configured to display the contents of various setting items on the display screen by transmitting control signals to a display unit (not shown).

[0060] <Packing method using a packing device> Next, a packing method using the packing device 1 will be described with reference to FIG. 7, the method includes at least a "box body preparation step (S1)" of preparing a box body B, a "guide member placement step (S2)" of placing a guide member 3 inside the box body B using a switching member 4, an "insertion step (S3)" of inserting an article S into the box body B, and a "detachment step (S4)" of detaching the guide member 3 from the box body B. These steps will be described in detail below. Note that explanations of other steps in the boxing work will be omitted. The packing device 1 controls the switching member 4 by the controller 6 to open and close the guide member 3. The packing device 1 also controls the insertion member 5 by the controller 6 to insert the article S into the box B.

[0061] In the "box body preparation step (S1)", the box body B is arranged so that the opening of the box body B faces sideways. At this time, the box body B is arranged so that the lower flap F4 is located below the placement table 2a.

[0062] In the "guide member arrangement step (S2)", the guide member 3 switched to the open state holds the flap F in an open state from inside the box body B, and covers the bonded portion G from inside the box body B. Specifically, before the article S is inserted, the first holding portion 10 and the second holding portion 20 are rotated by the switching member 4 to switch the guide member 3 to the open state. When the guide member 3 is switched to the open state, the right flap F1 is held by the first holding portion 10 and the bonding portion G is covered by the extending portion 40 at the same time. Therefore, the guide member 3 can be smoothly disposed inside the box body B.

[0063] Furthermore, in the guide member arrangement step (S2), before the article S is inserted, the extending portion 40 is arranged so as to cover the bonded portion G. Therefore, the extending portion 40 can be stably arranged at a position covering the bonded portion G. Note that the switching of the guide member 3 and the insertion of the article S may be performed simultaneously.

[0064] In the "insertion step (S3)", the article S is inserted into the box body B by the insertion member 5. Specifically, when the guide member 3 is opened by the switching member 4, the insertion member 5 is brought into contact with the rear end of the article S placed on the placement table 2a, and is operated to push the article S into the box body B so that it passes between the first holding part 10 and the second holding part 20. At this time, the inserting member 5 is operated to insert the article S with the first holding part 10 and the second holding part 20 opening the flap F and with the extending part 40 covering the bonding part G. This prevents the article S from getting caught on the flap F and the bonding part G, and allows the article S to be smoothly inserted into the box body B.

[0065] In the "removal step (S4)", after the article S is inserted, the first holding part 10 and the second holding part 20 are rotated by the switching member 4 to switch the guide member 3 to the closed state. When the guide member 3 is switched to the closed state, the extension portion 40 passes in front of the article S inserted into the box body B in the insertion direction of the article S. In this way, interference between the extension portion 40 and the article S can be suppressed.

However, the above embodiment is merely an example for facilitating understanding of the present invention, and is not intended to limit the present invention. The present invention can be modified or improved without departing from the spirit of the present invention, and the present invention naturally includes equivalents thereof.
