Description

Technical Field

[0001] The present disclosure relates to an inversion system for packaging boxes, and more particularly to an inversion system for packaging boxes in which one surface of each of the packaging boxes is opened and products are removed from each of the packaging boxes, wherein the inversion system inverts the empty packaging box so that a surface of the packaging box opposite the one opened surface is opened. Background Art

[0002] Boxes having a cubic shape are widely used as packaging containers for transporting and storing products.

[0003] Figure 1 The figure shows a packaging box with a widely used shape.

[0004] The packing box 1 is composed of panels of a paper material mainly coated with a synthetic resin film, and the upper and lower surfaces of the packing box 1 are covered and closed by four upper and lower surface panels whose upper and lower surfaces extend from the sides.

[0005] Since the upper and lower surfaces have the same structure, reference will be made to Figure 1 The top surface will be described below. Two of the four top surface panels 2 to 5 are paired and folded from their side edges so that the ends of the two panels touch or abut each other, thereby closing the top surface. A pair of second top surface panels 4 and 5 are folded face-to-face, and then another pair of first top surface panels 2 and 3 are folded face-to-face and positioned perpendicular to the pre-folded second top surface panels 4 and 5.

[0006] In this manner, the upper surface of the box is closed, the opposite ends of the first upper surface panels 2 and 3 folded and disposed above are coupled with tape, and thereby closed so that the packing box 1 cannot be opened by external force.

[0007] The packaging box 1 is closed by first constructing the lower surface in the same manner as the upper surface and arranging the product from the upper surface so that the product is contained inside the packaging box 1. Then, as described above, the packaging box 1 is closed by folding the upper surface panels 2 to 5 and coupling the ends of the first panels 2 and 3 using adhesive tape, and the closed packaging box 1 is transported.

[0008] At the same time, when the packaging box 1 constructed in this manner and containing products is opened with the intention of taking out the products, the tape connecting the first panels 2 and 3 to each other is cut, and all the second panels 2 and 5 are unfolded outward to open the upper surface and take out the products held in the inner part of the packaging box 1.

[0009] After the products are taken out, the lower surface of the empty packaging box 1 is unfolded in the same manner as the upper surface of the empty packaging box 1 , and the packaging boxes 1 are folded and stacked, and are unloaded as a recycling source.

[0010] In this way, the work of opening the packaging box 1, the work of extracting (or sucking) the products from the packaging box 1, the work of aligning and transporting the removed products, and the work of collecting the empty boxes from which the products were removed for recycling purposes generally rely on the physical labor of workers.

[0011] This manual labor takes time away from work, requires significant expenditure, and is performed by humans, so there is a risk that tasks may not be performed correctly.

[0012] In Korean Patent Publication No. 10-1554009 (Document 1) and No. 10-1527654 (Document 2), a configuration for facilitating the removal of products from a packaging box is disclosed, but no consideration is given to a configuration for automatically post-processing the empty packaging box for disposal or recycling after the products are removed from the empty packaging box. Summary of the Invention

[0013] Technical issues

[0014] The present disclosure discloses a configuration that is intended to provide an inversion system that inverts a package so as to invert an empty package, one surface of which is open and from which products are removed, and to open a surface opposite to the one opened surface.

[0015] Specifically, the present disclosure is intended to provide an inversion system that can automatically perform an inversion operation of an empty packaging box.

[0016] Furthermore, the present disclosure is intended to provide an inversion system that inverts an empty package such that after a product is taken out of a package with one surface opened, the opposite, unopened surface of the package can be opened without human intervention.

[0017] Technical Solutions

[0018] According to the present disclosure, in order to achieve at least one of the aforementioned purposes, an inversion system for packaging boxes according to the present disclosure is provided, wherein the inversion system inverts the box whose upper surface is opened and products are taken out so that the lower surface of the inverted empty box is arranged on the upper side of the empty box.

[0019] The inversion system according to the present disclosure comprises:

[0020] A first conveyor configured to transfer an empty package box with an opened upper surface from a removal position, at which the product is removed from the package box, to an inversion position for performing an inversion operation; a flipping device configured to hold the package box so as to be flipped around a rotation axis horizontal to the ground and to invert the package box; and a second conveyor configured to transport the inverted package box to a position for performing a bottom surface opening operation, wherein the flipping device holds two sides of the package box facing each other and uses a portion between the holding positions of the two held sides as a rotation axis to flip and invert the package box.

[0021] The turning device may hold two held sides facing each other among the sides of the packaging box, and may turn over and invert the two held sides using a portion existing between holding positions of the two held sides as a rotation axis.

[0022] In the inversion system of the present invention, the product can be taken out and the empty packaging box can be placed in an inverted position by the first conveyor. The upper and lower surfaces of the placed empty packaging box can be inverted by the second conveyor and transported to a position where the lower surface is opened.

[0023] As an additional feature of the present disclosure, in the inversion system of the present disclosure,

[0024] An upper surface panel covering the upper surface of the packaging box can be provided on the upper surface, and when the product is drawn out (or sucked) in the unfolded state, the upper surface panel is introduced into the inversion system, and

[0025] The flipping device may include: a movable frame that is actuated upward and downward in an inverted position; a pair of suction units that are respectively arranged at positions facing each other, actuated to approach or separate from each other, and provided with suction members configured to extract the sides of the packaging box at approximately the same time; and rods that are actuated upward and downward by the movable frame, and these rods are configured to make the upper surface panels in the open state and the unfolded state closely contact with the sides.

[0026] The empty packaging box from which the product is taken out may be in a state where the opened upper surface panel is unfolded. Therefore, the upper surface panel may become an obstacle factor in automating the post-processing of the empty packaging box.

[0027] In the aforementioned additional configuration of the present disclosure, before the operation of inverting the package, the package may be withdrawn after the side panels are brought into close contact with the sides of the package, and the overturning operation may be performed by lifting the package from the conveyor.

[0028] The upper surface panel unfolded by this operation does not become an obstacle to the upper surface panel of the packaging box. In particular, without installing a separate unit for folding the upper surface panel of the packaging box, the upper surface panels can be actuated together to make them contact tightly by the turning device.

[0029] Meanwhile, the upper surface panel may include a pair of first upper surface panels disposed vertically and facing each other. There is a case where the upper surface panel is configured as a pair, but a typical packing box has a pair of upper surface panels.

[0030] In this case, in the inversion system of the present disclosure, the rod may include a plurality of rods extending parallel to the extraction direction of the suction member, wherein, when the movable frame is actuated upward, each of these rods contacts each of the first upper surface panels, each of the suction units is provided with a mounting panel to which the suction member is attached, and each of the mounting panels can be configured to contact each of the second upper surface panels when the movable frame is actuated downward, and is configured to be in close contact with the side of the packaging box by actuating downward.

[0031] For the purpose of inverting the packages, the movable frame moves downward so that the packages set on the first conveyor to the second conveyor are held by the suction member, and moves downward so that the packages are turned over in a held state after the movable frame is raised, and turns the packages over to place the inverted packages on the first conveyor to the second conveyor again.

[0032] In addition to the lifting movement for the rotation of the packaging box, when the inversion of any packaging box in the packaging box is completed and the processed packaging box is taken out, the movable frame is raised to enter a waiting period. When the next packaging box is introduced, the movable frame moves down to hold the next packaging box.

[0033] According to the aforementioned configuration, the following operation can be performed: the upper surface panel of the newly introduced packaging box is actuated by downward movement so as to maintain close contact between the newly introduced packaging box and the side surface of the packaging box. In other words, the front end portion and the rod of the mounting panel bring the upper surface panel into contact with the side surface of the packaging box, and the front end portion and the rod of the mounting panel can move downward while docking with the first and second upper surface panels through the downward movement operation of the movable frame.

[0034] At the same time, each suction unit in the suction unit is provided with a plurality of suction members, and the suction members arranged below the flipping axis of the flipping device are drawn out by contacting with the side of the packaging box, and can preferably be drawn out to the second upper surface panel of the packaging box by contacting with the second upper surface panel of the packaging box.

[0035] As one of the specific embodiments of the inversion system of the present invention, the movable frame can move upward and downward, and may include: a first frame, which extends to be parallel to the flipping axis of the packaging box; and a pair of second frames, which are respectively arranged at opposite ends of the first frame and extend in the vertical direction, wherein the second frames are connected to move away from and approach the first frame along the flipping axis of the packaging box, and each suction unit in the suction unit is provided with a mounting panel, and the suction members are attached to these mounting panels; and a rotary drive motor, which is arranged in each second frame in the second frames, and is driven in a rotatable manner using the rotation axis of the packaging box that flips the mounting panel and drives the mounting panel as a rotation axis - the rotation axis is configured to rotate the mounting panel.

[0036] As an additional feature of the present disclosure,

[0037] The second conveyor may include a pair of conveyor belts extending from an inverted position to an open position of the bottom surface of the packaging box and parallel to each other, the first conveyor may include a pair of conveyor belts arranged at the inverted position and extending between the conveyor belts of the second conveyor to be perpendicular to the second conveyor, and the inversion system may also include a third conveyor extending from the outer part to a position adjacent to the second conveyor.

[0038] Beneficial effects

[0039] In the inversion system according to the present disclosure, the upper and lower surfaces of an empty package box from which products are taken out are automatically inverted, and the empty package box can be processed for disposal or recycling.

[0040] In order to bring the two pairs of upper surface panels into close contact with the packing box, the turnover device performs a close contact operation of downward movement of the movable frame by the downward movement of the movable frame without being provided with a configuration for independent movement.

[0041] Since the close contact operation is performed without a separate movement for bringing the upper surface panels of the packaging box into close contact, processing time is reduced. In addition, since a separate actuating unit for close contact operation is not required, the configuration of the inversion system can be simplified and can be produced cheaply.

[0042] Since the suction members are provided above and below the inversion axis of the packaging box, the inverting movement of the packaging box is smoothly performed and the packaging box is prevented from being separated during inversion.

[0043] According to the present disclosure, the configuration of the inversion system is made compact by providing a conveyor for transporting packages, and interference between various devices is eliminated. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] Hereinafter, as details for implementing the present disclosure, the configuration and operation of an inversion system for a packaging box according to an embodiment of the present disclosure will be described with reference to the accompanying drawings.

[0051] The inversion system of this embodiment is configured to Figure 1 After taking out the packaging box of the configuration shown in the figure, turn the empty box upside down.

[0052] After cutting the tape connecting the first upper surface panels 2 and 3 and then taking the product out of the packaging box 1 with the four upper surface panels 2 to 5 unfolded, the packaging box 1 is transported to the inversion system of this embodiment by a conveyor belt or other transport means.

[0053] In the inversion system of this embodiment, after the packaging box 1 is removed from the inversion system of this embodiment, and the tape is then cut so that the panel covering the opened lower surface is folded, the packaging box 1 is stacked on another packaging box and transported to another place for recycling.

[0054] First, refer to Figures 2 to 4 The overall configuration of the inversion system of the present embodiment will be described.

[0055] The inversion system of this embodiment generally includes: a third conveyor 90, which transports the empty package box 1 from the position where the product is taken out to a position adjacent to the position where the package box 1 is to be inverted; a second conveyor 80, which is arranged perpendicular to the third conveyor 90 and transports the inverted package box 1 to a position where the panel of the lower surface is opened; a first conveyor 70, which is arranged between the second conveyor 80 to be perpendicular to the second conveyor 80 and places the package box 1 transported by the third conveyor 90 in an inverted position; a flipping device 30, which holds, rotates and inverts the package box 1 set at the inverted position by the first conveyor 70; a first stop 21 and a second stop 22, which allow the package box 1 to be set at the inverted position; and a main frame 10, at which the flipping device 30, the stops 21 and 22 and the first conveyor 70 to the third conveyor 90 are installed.

[0056] The main frame 10 may be composed of a plurality of frames constructed independently of each other. In addition to the inversion system of this embodiment, the main frame 10 may be provided with an opening system for the packaging box 1 or a removal system for removing products from the packaging box 1 .

[0057] Hereinafter, for convenience, the main frame 10 is regarded as a single element and is provided at positions different from each other. Frames belonging to the main frame 10 are referred to as main frames and are denoted by the same reference numerals.

[0058] First, refer to Figures 5 to 7 The configuration of the turning device 30 will be described.

[0059] The inverting device 30 holds and rotates the packaging box 1 placed at the inverted position via the first conveyor 70 and the third conveyor 90 .

[0060] The conveyor belts of the first to third conveyors 70 to 90 are disposed on the same plane substantially parallel to the ground, and the turning device 30 is installed at a portion of the main frame 10 extending upward from the plane.

[0061] The main frame 10 includes four vertical channels 11 extending vertically and four horizontal channels 12 extending horizontally between the upper ends of the vertical channels 11. The space enclosed by the vertical channels 11 and the horizontal channels 12 forms an inversion area, where the packaging box 1 is inverted. Components of the inversion device 30 are connected to or suspended from the horizontal channels 12.

[0062] The turning device 30 includes movable frames 31 and 32 suspended from the horizontal channel 12 and configured to be movable upward and downward.

[0063] A vertically actuatable pneumatic cylinder 41 and four vertically extending linear guides 42 are coupled to the horizontal channel 12. A rotation axis ( Figure 7 A) a first frame 31 extending in parallel and a pair of second frames 32 extending in the vertical direction.

[0064] According to this configuration, when the pneumatic cylinder 41 is driven upward and downward, the first frame 31 and the second frame 32 are guided by the linear guide 42 and actuated in the vertical direction.

[0065] A linear actuator 43 including a pneumatic cylinder 41 and a linear guide 42 is provided at opposite ends of the first frame 31. The linear actuator 43 is driven in the extending direction of the first frame 31, that is, in the direction of the rotation axis A, and the upper end of the second frame 32 is coupled to the front end of the linear actuator 43.

[0066] According to this configuration, when the linear actuator 43 is driven, the second frame 32 is actuated in the same direction as or in the opposite direction to each other.

[0067] The rotation drive motors 44 are coupled to the lower end portions of the respective second frames 32. The rotation shafts (not shown) of the rotation drive motors 44 are disposed on the rotation axis A and are fixedly coupled to the second frames 32.

[0068] The mounting panel 33 is coupled to the lower end portion of the corresponding second frame 32, and suction members 45 and 46 as a suction unit are provided on the mounting panel 33. The mounting panel 33 is coupled to the rotation shaft of the rotation drive motor 44 so as to be rotatable.

[0069] The two mounting panels 33 are arranged facing each other, and a total of five suction members 45 and 46 are coupled to opposite surfaces of the mounting panels 33. Three first suction members 45 are arranged in parallel at the upper side of the rotation axis A, and two second suction members 46 are arranged at the lower side of the rotation axis A.

[0070] The suction members 45 and 46 are connected to a vacuum source to extract objects under vacuum conditions, and are used to extract and fix the packaging box 1 set between the mounting panels 33. This will be described below. The first suction member 45 extracts (or attracts) the upper surface panels 2 and 3 opened from the packaging box 1, and the second suction member 46 extracts the side of the packaging box 1.

[0071] Although not in Figure 6 Figure in the figure, but when referring to Figure 4 and Figure 5 When , the mounting brackets 35 extend from the mounting panels 33 at opposite sides of each of the mounting panels 33 , and the rod 36 is coupled to a front end portion of each of the mounting brackets 35 .

[0072] The rod 36 extends from the front end portion of the mounting bracket 35 in a direction parallel to the rotation axis A. The two rods 36 coupled to one of the mounting panels 33 are separated in the width direction of the packing box 1 .

[0073] Next, we will refer to Figures 2 to 4 The configurations of the first to third conveyors and the configurations of the stoppers 21 and 22 are described.

[0074] The third conveyor 90 includes two conveyor belts extending parallel to each other and extends from the position where the empty packaging box 1 is set after the product is taken out to the position where the second conveyor 80 is set.

[0075] The second conveyor 80 further includes two conveyor belts extending parallel to each other and extending from the inverted position to a position where the bottom surface of the inverted packaging box 1 is opened.

[0076] Since the extension directions of the third conveyor 90 and the second conveyor 80 are perpendicular to each other, the direction in which the third conveyor 90 introduces the package box 1 into the lower part of the flipping device 30 and the direction in which the second conveyor 80 pulls the inverted package box 1 out of the lower part of the flipping device 30 become perpendicular to each other.

[0077] At the same time, the first conveyor 70 also includes two conveyor belts extending parallel to each other, which form an assembly with rollers (not shown) and motors (not shown) that flip and drive the conveyor belts, and a pneumatic cylinder and a linear guide are arranged as a lifting device (not shown) for vertically lifting the assembly.

[0078] The first conveyor 70 and the third conveyor 90 are disposed in line with each other, and the pair of conveyor belts constituting the first conveyor 70 are disposed between the pair of conveyor belts constituting the second conveyor belt 80 .

[0079] According to this configuration, when the package box 1 is introduced from the position where the product is taken out to the lower part of the flipping device 30, that is, the inverted position, the first conveyor 70 is raised to the upper side of the second conveyor 80 by the lifting device (not shown) to receive the package box 1 introduced by the third conveyor 90, and the received package box 1 is set in the inverted position.

[0080] When the package box 1 is placed in the inverted position, the first conveyor 70 moves downward, and the package box 1 is supported by the second conveyor 80, and the inverting actuation caused by the overturning device 30 is performed. However, the first conveyor 70 may be placed at the same height as the second conveyor 80 so as to support the package box 1 together with the second conveyor 80, and the first conveyor 70 may support the package box 1 during the inverting actuation caused by the overturning device 30.

[0081] A first stopper 21 is provided in a direction opposite to the direction in which the packaging box 1 is introduced, and a second stopper 22 is provided in a direction in which the packaging box 1 is withdrawn by the third conveyor 90 .

[0082] The package box 1 is set in the inverted position by the actuation control of the first conveyor 70 to the third conveyor 90, and the movement of the package box 1 is restricted during the inverted actuation so that the misalignment is eliminated, so that the suction members 45 and 46 and the rod 36 accurately hold the package box 1 during the inverted actuation.

[0083] Will refer to Figures 8 to 10 The inverted actuation of the packaging box 1 according to the configuration described above will be described.

[0084] Before the packaging box 1 is introduced, the turning device 30 is arranged Figure 2 . The pneumatic cylinder 41 is actuated in a retracted state, and the first frame 31 and the second frame 32 are raised so that the suction members 45 and 46 and the rod 36 are set in the raised position. The second frame 32 is adapted to a state of being separated from each other by the retracting actuation of the linear actuator 43.

[0085] In this state, the packaging box 1 is introduced to the inverted position by the first conveyor 70 and the third conveyor 90 .

[0086] When the packaging box 1 is safely set and supported by the second conveyor 80 or the first conveyor 70, the pneumatic cylinder 41 is expanded and actuated to move the first frame 31 and the second frame 32 downward, and the mounting panel 33, suction members 45 and 46 and rod 36 attached to the frames also move downward.

[0087] The mounting panel 33 and the rod 36 are respectively actuated downward to contact the unfolded upper surface panels 2 and 6. The lower end surface of the mounting panel 33 moves downward while contacting the two second upper surface panels 4 and 5, and the second upper surface panels 4 and 5 are brought into close contact with the side of the packaging box 1. The corresponding rod 36 contacts the first upper surface panels 2 and 3 while also bringing the first upper surface panels 2 and 3 into close contact with the side of the packaging box 1.

[0088] When the lowering actuation is completed, the rotation axis of the rotary drive motor 44 is arranged at the approximate geometric center of the mutually facing sides of the packaging box 1. The geometric center of the side of the packaging box 1 is arranged on the rotation axis A.

[0089] The linear actuator 43 is expanded and actuated so that the mounting panels 33 are moved in a direction approaching each other. As a result, the suction members 45 and 46 attached to the mounting panels 33 are urged into contact with the packaging box 1.

[0090] The suction member 45 above the rotation axis A contacts the second upper surface panels 4 and 5 with which the side surfaces of the packaging box 1 are in close contact, and the suction member 46 below the rotation axis A contacts the side surfaces of the packaging box 1. In this state, the suction members 45 and 46 perform suction (or extraction or attraction) and actuation to extract the packaging box 1.

[0091] The pneumatic cylinder 41 is contracted and actuated in the withdrawn state, the turning device 30 is raised, and the packaging box 1 is also raised in the withdrawn state.

[0092] After being lifted a given distance from the second conveyor 80, the rotary drive motor 44 is rotated to turn the mounting panel 33 by an angle of 180 degrees. Therefore, the packaging box 1 is also turned over and inverted by an angle of 180 degrees.

[0093] The pneumatic cylinder 41 expands and activates again, causing the inverting device 30 to move downward. The package 1 also moves downward in its withdrawn state and is positioned above the second conveyor 80. The withdrawal activation of the suction members 45 and 46 ceases, and the linear actuator 43 contracts and activates, separating the mounting panels 33 from each other. Thus, the package 1 is placed in an inverted position on the second conveyor 80. The second conveyor 80 is activated, and the product is removed from the inverting device.

[0094] In the packaging box 1 taken out of the inversion system of this embodiment, the panel closing the bottom surface is opened and folded, and then stacked in an overlapping manner with another packaging box. However, this actuation is not caused by the inversion system of this embodiment, and therefore, the illustration and description of this actuation will be omitted.

[0095] In the packaging box 1 whose upper surface is opened and products are taken out therefrom by the configuration and actuation as described above, inversion actuation whereby the packaging box is turned upside down is automatically performed and carried out for subsequent processing.

[0096] Hereinabove, the configuration and operation of the inversion system for a packing box according to the embodiment of the present disclosure have been described, but various modifications and additions of elements may be made without being limited to the aforementioned embodiment without departing from the claims.
