Description

Technical Field

[0001] The present invention relates to the technical field of transportation containers, and particularly to a handling and stacking device for carton processing. Background Art

[0002] During the transportation of cartons, corresponding carton transportation devices are required, and their main function is to protect the stability and safety of cartons during transportation.

[0003] For example, the Chinese patent with the publication number "CN108408322A" discloses "a corrugated carton transportation device". This corrugated carton transportation device realizes the transportation of cartons through the coordinated use of a placement plate, a wooden board, a motor, a turntable, a runner, a second connecting rod, a fixed block, a first connecting rod, a base, wheels, a push rod, and a controller. And during the working process, the cartons are stacked on the upper surface of the placement plate. Due to the structural characteristics of the cartons, they are relatively fluffy. Since the stacking and pressing method is not adopted, the following defects are likely to exist: First, the fluffiness results in a small number of cartons carried at a time (the upward fluffing gap of the cartons increases with the increase in their number); Second, since the cartons stacked upward will cause extrusion on the cartons at the bottom layer, once the stacked weight exceeds the compressive capacity of the cartons at the bottom layer, the cartons at the bottom layer will undergo plastic deformation, seriously affecting their service life and use strength. Summary of the Invention

[0015] Compared with the prior art, the present invention provides a handling and stacking device for carton processing, having the following beneficial effects: It can perform stacking and squeezing locking on stacked cartons, thereby improving the stability and reliability of the cartons during transportation. Moreover, when performing pressing and locking, the device can control the pressure received by the bottommost carton, thereby preventing the occurrence of plastic deformation of the cartons caused by excessive pressure to ensure the usability of the overall cartons after transportation.

[0016] By setting up a negative-pressure telescopic locking mechanism, when the air extraction device is working, the gas located below the piston body will be pumped outwards. At this time, the piston body drives the longitudinal telescopic rod, the curved connecting rod and the insertion tube structure to move downward, and finally drives the hollow partition board to press the cardboard box downward, thereby reducing the height of this layer of cardboard box at this time to ensure that there is more space in the cardboard box storage cavity for storing cardboard boxes. Pressing and stacking will tightly fix the cardboard boxes, thereby improving the stability and quantity of the cardboard boxes during transportation.

[0017] By setting up a threaded limit mechanism, due to the threaded connection, the upper threaded sleeve cannot make the hollow partition board in this area move downward continuously. After the hollow partition board in this area is subjected to the pressure of the cardboard box placed on its upper surface, this pressure will be directly transmitted downward through the top fixed plate, the longitudinal contact rod, the upper threaded sleeve and the longitudinal support column, and finally transmitted to the surface of the transportation cabinet, so that no additional pressure will be generated on the cardboard boxes in this area. The compressed No. 2 helical spring can produce a pre-tightening effect between the threaded structures to prevent loosening due to jolting during transportation. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manner

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figure 1 、 Figure 2 and Figure 3 A handling and stacking device for carton processing, including a transportation cabinet 1 with rollers 2 installed at the bottom, a carton storage cavity 3 arranged in the transportation cabinet 1, a hollow partition board 4 with a rectangular cavity 5 inside, an air extraction channel 7 for extracting the air in the rectangular cavity 5 and equipped with a gas valve, and tube insertion holes 6 arranged on the upper surface of the hollow partition board 4 and close to its four corners and communicating with the rectangular cavity 5. During operation, the hollow partition board 4 can stack the cartons located below it in a pressing manner in layers, and the hollow partition board 4 can also bear the pressure of the cartons on its upper surface to prevent the cartons above from exerting additional pressure on the cartons below, thereby ensuring the service life of the cartons.

[0022] In order to use gas negative pressure to achieve a pressing stacking effect on cartons, thereby improving the stability and quantity of cartons during transportation, please refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 5, it is necessary to set up a negative pressure telescopic locking mechanism 8, which is internally provided with a longitudinal support column 81 with a hollow structure inside, a piston body 86 placed inside the longitudinal support column 81 and moving downward when subjected to gas suction force, and an insertion tube structure 89 that can be inserted into the tube insertion hole 6 of the tube body and cause the hollow partition plate 4 to move longitudinally. When the air extraction device works, the gas below the piston body 86 will be pumped outwards. At this time, the piston body 86 drives the longitudinal telescopic rod 87, the curved connecting rod 88 and the insertion tube structure 89 to move downward, and finally drives the hollow partition plate 4 to press the cardboard box downward, thereby reducing the height of the cardboard box at this layer to ensure that there is more area left in the cardboard box storage cavity 3 for storing cardboard boxes. Pressing and stacking will tightly fix the cardboard boxes, thereby improving the stability and quantity of the cardboard boxes during transportation.

[0023] For the specific structure of the negative pressure telescopic locking mechanism 8, please refer to Figure 4 and Figure 5 , and also includes a first helical spring 811. A first connecting plate 82 is provided at the bottom of the longitudinal support column 81. An external thread structure 83 is provided on the column body of the longitudinal support column 81. A longitudinal component moving cavity 84 is provided inside the longitudinal support column 81. A first rod body through hole 85 is provided at the top of the longitudinal component moving cavity 84. A piston body 86 that can move along its axial direction is placed inside the longitudinal component moving cavity 84. The upper end of the piston body 86 is provided with a longitudinal telescopic rod 87 that is integrally formed with it and penetrates through the first rod body through hole 85. A first helical spring 811 in a compressed state is sleeved around the rod body of the longitudinal telescopic rod 87 inside the longitudinal component moving cavity 84. The top of the longitudinal telescopic rod 87 is provided with a curved connecting rod 88 with an integral structure. The top port of the curved connecting rod 88 is provided with an insertion tube structure 89 that can be inserted downward into the tube insertion hole 6 of the tube body. A second connecting plate 812 with a horizontal connecting surface is fixedly installed above the curved connecting rod 88. Gas flow holes 810 communicating the rectangular cavity 5 and the area below the longitudinal component moving cavity 84 are provided inside the piston body 86, the longitudinal telescopic rod 87, the curved connecting rod 88 and the insertion tube structure 89. The cross-sectional structure shape of the first rod body through hole 85 is the same as that of the longitudinal telescopic rod 87, both are polygonal structures, and the cross-sectional structure size of the first rod body through hole 85 matches the cross-sectional structure size of the longitudinal telescopic rod 87. After the insertion tube structure 89 is inserted into the tube insertion hole 6 of the tube body, a sealing ring placed inside the tube insertion hole 6 is used to prevent gas leakage.

[0024] To prevent the upper cardboard boxes separated by the hollow partition plate 4 from exerting additional pressure on the lower cardboard boxes, please refer to Figure 1 , Figure 2 and Figure 6, it is necessary to set a threaded limit mechanism 9, which is internally provided with an upper threaded sleeve 93 installed at the column position of the longitudinal support column 81 through a threaded structure, and a top fixed disk 96 that can abut against the annular end of the upper threaded sleeve 93 and limit the low point of the movement of the hollow partition plate 4. When the air extraction work is completed, the lower threaded sleeve 91 and the upper threaded sleeve 93 are rotated respectively, and the upper threaded sleeve 93 is made to abut against the bottom end of the longitudinal abutting rod 98. Then, the second helical spring 94 is in a compressed state. At this time, due to the threaded connection, the upper threaded sleeve 93 cannot make the hollow partition plate 4 in this area move downward continuously. After the hollow partition plate 4 in this area is subjected to the pressure of the carton placed on its upper surface, this pressure will be directly transmitted downward through the top fixed disk 96, the longitudinal abutting rod 98, the upper threaded sleeve 93 and the longitudinal support column 81, and finally transmitted to the surface of the transportation cabinet 1, so that no additional pressure will be generated on the carton in this area. The compressed second helical spring 94 can produce a pre-tightening effect on the threaded structure, preventing looseness caused by jolting during transportation.

[0025] For the specific structure of the threaded limit mechanism 9, please refer to Figure 6 , it also includes a lower threaded sleeve 91 and a top fixed disk 96. Lower internal threaded holes 92 and upper internal threaded holes 95 sleeved on the column position of the longitudinal support column 81 through threaded structures are respectively arranged at the centers of the lower threaded sleeve 91 and the upper threaded sleeve 93. A second helical spring 94 that can be in a compressed state is installed between the lower threaded sleeve 91 and the upper threaded sleeve 93. A rod body fixing hole 97 fixedly installed at the top rod position of the longitudinal telescopic rod 87 is arranged at the center of the top fixed disk 96. A longitudinal abutting rod 98 that can abut against the annular end of the upper threaded sleeve 93 is fixedly installed on the lower surface of the top fixed disk 96. The threaded structure includes an internal threaded structure arranged on the circumferential inner wall of the lower internal threaded hole 92 and an external threaded structure 83, and the internal threaded structure matches the external threaded structure 83. The threaded structure includes an internal threaded structure arranged on the circumferential inner wall of the upper internal threaded hole 95 and an external threaded structure 83, and the internal threaded structure matches the external threaded structure 83.

[0026] To achieve the function of rapid installation and disassembly between components, please refer to Figure 1 , Figure 2 , Figure 7 and Figure 8, it is necessary to set up a quick docking mechanism 10, which internally has a locking disc 101 that can be fixedly installed on the bottom surface of the transport cabinet 1 and the upper surface of the second connecting plate 812, a connecting sleeve 103 that can be fixedly installed at the bottom of the first connecting plate 82, and a longitudinal rotating shaft 105 that is rotationally inserted into the locking disc 101 to achieve a locking effect between the locking disc 101 and the connecting sleeve 103. When connection is required, only need to pass the plum blossom-shaped chuck 108 through the plum blossom-shaped movable groove 106 and then directionally rotate the longitudinal rotating shaft 105 to make the plum blossom-shaped chuck 108 snap into the plum blossom-shaped locking cavity 107. When disassembly is required, just do the opposite, thus realizing the quick installation and disassembly functions between components.

[0027] Regarding the specific structure of the quick docking mechanism 10, please refer to Figure 7 and Figure 8 , it also includes a plum blossom-shaped chuck 108. A third connecting plate 102 is installed at the bottom of the locking disc 101 on the bottom surface of the transport cabinet 1 and the upper surface of the second connecting plate 812. A fourth connecting plate 104 is installed at the top of the connecting sleeve 103 at the bottom of the first connecting plate 82. The bottom end of the connecting sleeve 103 is installed with a rotatable longitudinal rotating shaft 105 through a bearing. The locking disc 101 internally has a plum blossom-shaped movable groove 106 with an open top end. The locking disc 101 is provided with a plum blossom-shaped locking cavity 107 at the bottom end of the plum blossom-shaped movable groove 106. The bottom end of the longitudinal rotating shaft 105 is provided with a plum blossom-shaped chuck 108 that can pass through the plum blossom-shaped movable groove 106 and be locked inside the plum blossom-shaped locking cavity 107. After the plum blossom-shaped chuck 108 passes through the plum blossom-shaped movable groove 106, it can be snapped into the plum blossom-shaped locking cavity 107 by directional rotation to prevent the plum blossom-shaped chuck 108 from longitudinally disengaging from the locking disc 101.

[0028] In use, it needs to be used in conjunction with a gas extraction device capable of controlling the pressure of the extracted gas. First, rotate the corresponding curved connecting rod 88. Since the longitudinal rotating shaft 105 has the function of being rotatable, the curved connecting rod 88 is turned away from the carton stacking area. Then stack the cartons on the upper surface of the transport cabinet 1 and stack them layer by layer upwards. When the stacking height of the cartons is greater than the horizontal height of the second connecting plate 812 of this layer, place the hollow partition plate 4 on the top of the highest carton. Then, pull the curved connecting rod 88 upwards and rotate the curved connecting rod 88. Finally, make the insertion tube structure 89 insert into the corresponding tube insertion hole 6 until the four insertion tube structures 89 are correspondingly inserted into the four tube insertion holes 6. Then use the gas extraction device to extract the gas inside the device through the gas extraction channel 7. Under the action of the gas negative pressure, the piston body 86 will drive the hollow partition plate 4 to move downwards. At this time, it should be noted that according to the normal pressure that the transported cartons can withstand, control the vacuum air pressure value at this time so that the air pressure value is close to but less than the pressure intensity that the cartons can normally withstand. When the gas negative pressure value below the piston body 86 reaches this range, turn off the gas extraction device, then rotate the lower threaded sleeve 91 and the upper threaded sleeve 93 respectively, and make the upper threaded sleeve 93 abut against the bottom end of the longitudinal abutting rod 98, and then make the second helical spring 94 in a compressed state.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
