Description

Technical Field

[0001] The invention discloses a box supporting device for an automatic case packing machine, belonging to the technical field of packaging. Background Art

[0002] Cartons are the most common packaging carriers. During the automated packaging process, supporting the carton by shoring the flaps at the carton ports is a crucial step. Several technical solutions for automatically supporting cartons are currently available, such as those described in patents with publication numbers CN102358448A, CN203318730U, CN214875994U, CN216270158U, CN220350105U, CN220577632U, CN220865818U, and CN220997030U. However, these solutions can only support one carton at a time, resulting in low efficiency.

[0003] In order to improve work efficiency, some technical solutions that can perform box-supporting operations on multiple cartons at the same time have appeared on the market. For example, in the technical solution disclosed in the Chinese utility model patent with publication number CN210028146U, two rotating shafts are provided, and the two rotating shafts are respectively driven to rotate by a motor. A number of cylinders are respectively provided on the two rotating shafts, and the cylinders are used to drive the corresponding box-supporting plates to achieve box-supporting. The defect of this technical solution is that the number of cylinders required is four times the number of cartons, so the cost is relatively high. In the technical solution disclosed in the Chinese utility model patent with publication number CN208325783U, the number of power sources required is the same as the number of cartons to be supported at the same time, which reduces the number of power sources to be arranged and reduces the cost. However, in this solution, gear meshing is used to realize the box-supporting action of the four folds of the carton using one power source, and its structure is relatively complex. In the technical solution disclosed in the Chinese utility model patent with publication number CN208325783U, similar to the technical solution of CN208325783U, both use gear meshing to achieve the box-supporting action while reducing the number of power sources arranged, so it also has the defect of a more complex structure.

[0004] Therefore, designing a solution for a box-supporting device that can simultaneously support multiple cartons and has the advantages of simple structure and low cost has become an urgent problem to be solved in this field. Utility Model Content

[0005] The technical problem to be solved by the present invention is: to overcome the shortcomings of the existing technology and provide a box-supporting device for an automatic cartoning machine which utilizes a group of first power sources and multiple groups of second power sources arranged vertically with the same number of cartons to achieve simultaneous box-supporting operations on multiple cartons, thereby minimizing the number of power sources and reducing costs and structural complexity.

[0006] The technical solution adopted by the utility model to solve the technical problem is as follows: the box supporting device of the automatic cartoning machine includes a main frame and a box supporting plate group acting on carton folding, and is characterized in that: a plurality of box supporting stations are arranged in the main frame, and the box supporting plate group includes a first box supporting plate group and a second box supporting plate group arranged perpendicular to each other in each box supporting station;

[0007] A first power source is arranged on the upper part of the main frame along the arrangement direction of the box supporting stations, and the first power source is connected to all the first box supporting plate groups. A plurality of second power sources are also arranged on the upper part of the main frame perpendicular to the arrangement direction of the box supporting stations, and each second power source is connected to the corresponding second box supporting plate group.

[0008] Preferably, the first power source includes a first piston mechanism relatively arranged at both ends of the main frame, the first piston mechanisms at both ends are respectively connected to a first rotating shaft, the two first rotating shafts are horizontally arranged above the main frame, and all the first box supporting plate groups are arranged in sequence at intervals on the surfaces of the two first rotating shafts.

[0009] Preferably, each group of first box-supporting plates includes two short-side box-supporting plates arranged opposite to each other, and the two short-side box-supporting plates are arranged on the surfaces of the two first rotating shafts respectively.

[0010] Preferably, the two first rotating shafts are both supported by a bearing seat, and the ends of the two first rotating shafts at different positions extend to the outside of the bearing seat and are respectively connected to the piston rod of the first piston mechanism on the corresponding side through a hinge plate.

[0011] Preferably, each second power source includes a second piston mechanism relatively arranged at both ends of the main frame, the second piston mechanisms at both ends are respectively connected to a second rotating shaft, and the corresponding two second rotating shafts are respectively connected to a second box supporting plate group.

[0015] Preferably, the main frame includes columns at four corners and a plurality of top beams connecting all the columns, and the first power source and the second power source are both fixed on the outside of the top beams.

[0023] Among them: 1, short side drive cylinder 2, short side bearing seat 3, long side support box plate 4, first long side bearing seat 5, short side rotation axis 6, second long side bearing seat 7, short side support box plate 8, long side drive cylinder 9, long side rotation axis 10, hinged plate 11, long side top beam 12, short side top beam 13, column 14, bottom beam 15, bottom plate. DETAILED DESCRIPTION

[0024] Figures 1 to 4 This is the best embodiment of the present invention, Figures 1 to 4 The utility model is further described.

[0025] like Figures 1 to 4 As shown, a case supporting device for an automatic case packing machine (hereinafter referred to as the case supporting device) includes a rectangular main frame. The main frame includes four vertically arranged columns 13 located at the four corners of the main frame. A base plate 15 is provided at the bottom of each of the four columns 13.

[0026] The tops of the four columns 13 are connected as a whole by four horizontally arranged top beams. Two opposing top beams are of equal length, while two adjacent top beams are of different lengths, giving the top of the main frame a rectangular structure. The two longer top beams are the long-side top beams 11, forming the two long sides of the main frame, while the two shorter top beams are the short-side top beams 12, forming the two short sides of the main frame. A bottom beam 14 is also provided below each of the four top beams. Each bottom beam 14 is the same length as the corresponding top beam above it, and each bottom beam 14 is connected to a corresponding column 13 at both ends.

[0027] A short-side drive cylinder 1 is disposed on the outer surface of each short-side top beam 12. The bodies of the two short-side drive cylinders 1 are horizontally fixed to the sides of the corresponding short-side top beam 12, with the piston rods of the two short-side drive cylinders 1 facing in opposite directions. Two short-side rotation shafts 5 are spaced apart above the main frame, and both short-side rotation shafts 5 are arranged along the length of the main frame. The two short-side rotation shafts 5 are supported at both ends by short-side bearing blocks 2, which are fixed to the top of the short-side top beam 12 on the corresponding side. The two ends of the short-side rotation shafts 5 extend to the outside of the corresponding short-side top beam 12 and are fixed to a hinge plate 10. The hinge plates 10 at both ends are hinged to the piston rods of the corresponding short-side drive cylinders 1. Therefore, when the piston rods of the two short-side drive cylinders 1 are actuated, they drive the two short-side rotation shafts 5 to rotate in opposite directions.

[0028] On the surface of each short side rotating shaft 5, multiple short side supporting boxes 7 are arranged at intervals. The number of short side supporting boxes 7 on the surfaces of the two short side rotating shafts 5 is equal and they are arranged opposite to each other. The two short side supporting boxes 7 arranged opposite to each other on the surfaces of the two short side rotating shafts 5 form a group of short side supporting boxes. When the piston rods of the two short side driving cylinders 1 move, the two short side supporting boxes 7 in each group of short side supporting boxes are driven to swing in opposite directions through the two short side rotating shafts 5.

[0029] Multiple long-side drive cylinders 8 are respectively installed on the outer sides of the two long-side top beams 11. The bodies of the long-side drive cylinders 8 on both sides are horizontally fixed to the sides of the corresponding long-side top beams 11. The piston rods of the multiple long-side drive cylinders 8 on the outer side of the same long-side top beam 11 face the same direction, while the piston rods of the long-side drive cylinders 8 on the outer sides of the two long-side top beams 11 face opposite directions.

[0030] The two long-side drive cylinders 8 on the outer sides of the two long-side top beams 11 are grouped together, meaning the piston rods of the two long-side drive cylinders 8 in each group face opposite directions. The number of long-side drive cylinder 8 groups between the two long-side top beams 11 is the same as the number of short-side support plate groups described above, and they correspond one-to-one: the two short-side support plates 7 in each short-side support plate group are located on the inner sides of the two opposing long-side drive cylinders 8.

[0031] Multiple groups of long-side rotating shafts 9 are arranged at intervals on the upper part of the main frame. Each group of long-side rotating shafts 9 includes two shafts, and the number corresponds to the number of groups of long-side driving cylinders 8. All long-side rotating shafts 9 are located below the two short-side rotating shafts 5. Take any group of long-side rotating shafts 9 as an example: the two long-side rotating shafts 9 of each group are supported at both ends by long-side bearing seats, and the long-side bearing seats at the ends of the two long-side rotating shafts 9 are fixed to the top of the long-side top beam 11 on the corresponding side. The two ends of the two long-side rotating shafts 9 at different positions extend to the outside of the long-side top beam 11 on the corresponding side and are fixed to a hinge plate 10 respectively. The hinge plates 10 at both ends are hinged to the piston rods of the corresponding long-side driving cylinders 8 respectively. Therefore, when the piston rods of the two long-side driving cylinders 8 move, they drive the two long-side rotating shafts 9 to rotate in opposite directions.

[0032] Among all the long side rotating shafts 9 located at the upper part of the main frame, the two long side rotating shafts 9 located at both ends are supported by the first long side bearing seat 4, and several long side rotating shafts 9 located in the middle are supported by the second long side bearing seat 6. The difference between the first long side bearing seat 4 and the second long side bearing seat 6 is that the second long side bearing seat 6 can connect two adjacent long side rotating shafts 9 at the same time.

[0033] A long side support box plate 3 is also provided on the surface of each long side rotating shaft 9. The two long side support box plates 3 on the surfaces of each group of two long side rotating shafts 9 are arranged opposite to each other and form a group of long side support box plates. When the piston rods of all the long side driving cylinders 8 on both sides move at the same time, the two long side support box plates 3 in each group of long side support box plates are driven to swing in opposite directions through the corresponding long side rotating shafts 9.

[0034] Each group of long side support box plates is simultaneously located between the corresponding two long side drive cylinders 8, and the two long side support box plates 3 in each group of long side support box plates and the two short side support box plates 7 simultaneously located between the corresponding two long side drive cylinders 8 are arranged in a rectangular shape.

[0035] The specific working process and working principle are as follows:

[0036] This carton-supporting mechanism has three long-side support plates and three short-side support plates, allowing it to support three cartons simultaneously. Each three cartons are transported into the carton-supporting mechanism via a conveyor mechanism (such as a conveyor belt, not shown) and passed through the main frame. Once the three cartons are in position, each carton is positioned below its corresponding long-side support plate and short-side support plate groups.

[0037] At this point, all the short-side drive cylinders 1 and long-side drive cylinders 8 operate simultaneously. After the piston rods of the two short-side drive cylinders 1 are released, they drive the two short-side rotating shafts 5 to rotate in the opposite direction, simultaneously causing all the short-side support panels 7 to swing in the opposite direction. After the piston rods of all six long-side drive cylinders 8 are released, they drive the two long-side rotating shafts 9 of each group to rotate in the opposite direction, simultaneously causing the two long-side support panels 3 of each group to swing in the opposite direction.

[0038] For each carton, its two short-side support panels 7 and two long-side support panels 3 simultaneously swing outward, opening the four flaps at their ends and completing the box-supporting operation. After the items to be packed are placed in the corresponding carton, all short-side drive cylinders 1 and long-side drive cylinders 8 simultaneously reset, and the short-side support panels 7 and long-side support panels 3 on the top of each carton swing inward, separating from the flaps. The carton is then transported to the next process via the conveyor, and this cycle repeats.

[0039] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation thereto. Any person skilled in the art may utilize the above disclosure to modify or remodel the present invention into equivalent embodiments. However, any simple modification, equivalent variation, or modification of the above embodiment that does not depart from the technical content of the present invention and is based on the technical essence of the present invention shall still fall within the scope of protection of the present invention.
