Description

Technical Field

[0001] The present invention relates to the technical field of transport containers, in particular to a transporting and stacking device for processing cartons. Background Art

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

[0003] For example, a Chinese patent with publication number "CN108408322A" discloses "a corrugated cardboard box transporting device", which realizes the transportation of cartons through the coordinated use of a placement board, a wooden board, a motor, a turntable, a rotating wheel, a second connecting rod, a fixed block, a first connecting rod, a base, wheels, a push rod and a controller. During operation, the cartons are stacked on the upper surface of the placement board. Due to the structural characteristics of the cartons, they are relatively fluffy. Since no stacking and pressing method is adopted, the following defects are prone to occur: First, the fluffiness leads to a small number of cartons carried at a time (the upward fluffy gap of the cartons increases with the number of cartons); second, the cartons stacked upward will squeeze the cartons at the bottom layer. Once the stacked weight exceeds the compressive strength of the cartons at the bottom layer, the cartons at the bottom layer will be plastically deformed, seriously affecting their service life and usage strength.

Moreover, when pressing and locking, the device can control the pressure on the bottom cartons, thereby preventing the plastic deformation of the cartons caused by excessive pressure, so as to ensure the usability of the entire carton after transportation.

[0017] By setting up a negative pressure telescopic locking mechanism, when the vacuum equipment is working, the gas located under the piston body will be drawn outward. 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 dividing plate to press the carton downward, thereby reducing the height of the carton layer at this time to ensure that more area is left in the carton storage cavity for carton storage. Pressing and stacking will make the cartons tightly fixed, thereby improving the stability and quantity of the cartons during transportation.

[0018] By setting up a threaded limiting mechanism, the upper threaded sleeve cannot make the hollow partition plate in this area continue to move downward due to the threaded structure connection. After the hollow partition plate in this area is subjected to the pressure of the carton placed on its upper surface, the pressure will be directly transmitted downward through the top fixed plate, the longitudinal resistance rod, the upper threaded sleeve and the longitudinal support column, and finally transmitted to the surface of the transport cabinet, so that no additional pressure will be generated on the cartons in this area. The compressed No. 2 coil spring can produce a pre-tightening effect between the threaded structures to prevent loosening due to bumps during transportation. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1 、 Figure 2 and Figure 3 A handling and stacking device for carton processing includes a transport cabinet 1 with rollers 2 installed at the bottom, a carton storage cavity 3 arranged in the transport cabinet 1, a hollow partition plate 4 with a rectangular cavity 5 arranged inside, an exhaust channel 7 for extracting air from the rectangular cavity 5 and equipped with a gas valve, and a tube insertion hole 6 arranged on the upper surface of the hollow partition plate 4 and close to its four corners and connected to the rectangular cavity 5. When working, the hollow partition plate 4 can press and stack the cartons below it in layers, and the hollow partition plate 4 can withstand the pressure of the cartons on its upper surface to prevent the cartons above from generating additional pressure on the cartons below it, thereby ensuring the service life of the cartons.

[0030] In order to use the negative pressure of gas to achieve a pressing stacking effect on the cartons, thereby increasing the stability and quantity of the 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 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, and an insertion tube structure 89 that can be inserted into the tube insertion hole 6 and make the hollow partition plate 4 produce a longitudinal movement effect. When the vacuum equipment is working, the gas below the piston body 86 will be drawn out. 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 carton downward, thereby reducing the height of the layer of cartons at this time, so as to ensure that more area is left in the carton storage cavity 3 for carton storage. Pressing and stacking will make the cartons tightly fixed, thereby improving the stability and quantity of the cartons during transportation.

[0031] For the specific structure of the negative pressure telescopic locking mechanism 8, please refer to Figure 4 and Figure 5 , also includes a No. 1 coil spring 811, a No. 1 connecting plate 82 is provided at the bottom of the longitudinal support column 81, an external thread structure 83 is provided at the column body of the longitudinal support column 81, a longitudinal longitudinal component movable cavity 84 is provided inside the longitudinal support column 81, and a No. 1 rod body through-hole 85 is provided at the top of the longitudinal component movable cavity 84. A piston body 86 capable of moving along its axial direction is placed inside the longitudinal component movable cavity 84, and a longitudinal telescopic rod 87 which is an integral structure with it and passes through the No. 1 rod body through-hole 85 is provided at the upper end of the piston body 86. The longitudinal telescopic rod 87 is provided with a No. 1 coil spring 811 in a compressed state on the outer periphery of the rod body located inside the longitudinal component movable cavity 84, and a curved connecting rod 88 of an integral structure is provided at the top of the longitudinal telescopic rod 87. The top port is provided with an insertion tube structure 89 that faces downward and can be inserted into the tube body insertion hole 6. A second connecting plate 812 with a connecting surface in a horizontal state is fixedly installed above the curved connecting rod 88. The piston body 86, the longitudinal telescopic rod 87, the curved connecting rod 88 and the insertion tube structure 89 are internally provided with a gas flow hole 810 that connects the rectangular cavity 5 and the area below the longitudinal component active cavity 84. The structural shape of the cross section of the No. 1 rod body through-hole 85 is consistent with the structural shape of the cross section of the longitudinal telescopic rod 87, both of which are polygonal structures, and the structural dimensions of the cross section of the No. 1 rod body through-hole 85 match the structural dimensions of the cross section of the longitudinal telescopic rod 87. After the insertion tube structure 89 is inserted into the tube body insertion hole 6, gas leakage is prevented by a sealing ring placed inside the tube body insertion hole 6.

[0032] In order to prevent the upper carton divided by the hollow dividing plate 4 from exerting additional pressure on the lower carton, please refer to Figure 1 、 Figure 2 and Figure 6, it is necessary to set up a threaded limiting mechanism 9, which is internally provided with an upper threaded sleeve 93 installed at the column body of the longitudinal support column 81 through a threaded structure, and a top fixed plate 96 that can abut against the annular end of the upper threaded sleeve 93 and can limit the movement of the hollow dividing plate 4 to the lower point. 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 abutted against the bottom end of the longitudinal abutment rod 98, and then the No. 2 coil spring 94 is in a compressed state. At this time, the upper threaded sleeve 93 is in a compressed state due to the threaded structure. The connection prevents the hollow partition plate 4 in this area from continuing to move downward. After the hollow partition plate 4 in this area is subjected to the pressure of the cartons placed on its upper surface, the pressure will be directly transmitted downward through the top fixed plate 96, the longitudinal resistance rod 98, the upper threaded sleeve 93 and the longitudinal support column 81, and finally transmitted to the surface of the transport cabinet 1, so that no additional pressure will be generated on the cartons in this area. The compressed No. 2 coil spring 94 can produce a pre-tightening effect between the threaded structures to prevent the occurrence of loosening due to bumps during transportation.

[0033] For the specific structure of the threaded limiting mechanism 9, please refer to Figure 6 , also includes a lower threaded sleeve 91 and a top fixed plate 96, the centers of the lower threaded sleeve 91 and the upper threaded sleeve 93 are respectively provided with a lower internal threaded hole 92 and an upper internal threaded hole 95 which are sleeved on the column body of the longitudinal support column 81 through a threaded structure, and a No. 2 coil spring 94 which can be in a compressed state is installed between the lower threaded sleeve 91 and the upper threaded sleeve 93, and the center of the top fixed plate 96 is provided with a rod body fixing hole 97 which is fixedly installed at the top rod body of the longitudinal telescopic rod 87, and the lower surface of the top fixed plate 96 is fixedly installed with a longitudinal resistance rod 98 which can resist the annular end portion on the upper threaded sleeve 93. The threaded structure includes an internal threaded structure and an external threaded structure 83 provided on the inner wall of the circumference of the lower internal threaded hole 92, and the internal threaded structure matches the external threaded structure 83, and the threaded structure includes an internal threaded structure and an external threaded structure 83 provided on the inner wall of the circumference of the upper internal threaded hole 95, and the internal threaded structure matches the external threaded structure 83.

[0034] For quick installation and removal of components, see Figure 1 、 Figure 2 、 Figure 7 and Figure 8, it is necessary to set up a quick docking mechanism 10, which is internally provided with a locking plate 101 that can be fixedly mounted on the bottom surface of the transport cabinet 1 and the upper surface of the No. 2 connecting plate 812, a connecting sleeve 103 that can be fixedly mounted on the bottom of the No. 1 connecting plate 82, and a longitudinal rotating shaft 105 that is inserted into the locking plate 101 in a rotating manner, so that a locking effect is achieved between the locking plate 101 and the connecting sleeve 103. When connection is required, it is only necessary to pass the plum blossom-shaped chuck 108 through the plum blossom-shaped movable groove 106, and then rotate the longitudinal rotating shaft 105 in a direction so that the plum blossom-shaped chuck 108 is stuck into the plum blossom-shaped locking cavity 107. When disassembly is required, the opposite is sufficient, thereby realizing the rapid installation and disassembly functions between components.

[0035] For the specific structure of the quick docking mechanism 10, please refer to Figure 7 and Figure 8 , also includes a plum blossom-shaped chuck 108, the bottom of the locking plate 101 is provided with a No. 3 connecting plate 102 installed on the bottom surface of the transport cabinet 1 and the upper surface of the No. 2 connecting plate 812, the top of the connecting sleeve 103 is provided with a No. 4 connecting plate 104 installed on the bottom of the No. 1 connecting plate 82, the bottom end of the connecting sleeve 103 is provided with a rotatable longitudinal shaft 105 through a bearing, and the interior of the locking plate 101 is provided with a plum blossom-shaped movable groove 106 with an open top end. The locking disk 101 is provided with a plum blossom-shaped locking cavity 107 at the bottom end of the plum blossom-shaped movable groove 106, and 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 lock inside the plum blossom-shaped locking cavity 107. After passing through the plum blossom-shaped movable groove 106, the plum blossom-shaped chuck 108 can be stuck into the inside of the plum blossom-shaped locking cavity 107 through directional rotation to prevent the plum blossom-shaped chuck 108 from longitudinally detaching from the locking disk 101.

[0036] When in use, it is necessary to cooperate with the exhaust equipment that can control the pressure of the extracted gas. First, rotate the corresponding curved connecting rod 88. Since the longitudinal rotating shaft 105 has the function of rotation, the curved connecting rod 88 is turned back to the carton stacking area, and then the cartons are stacked on the upper surface of the transport cabinet 1, and stacked up layer by layer. When the stacking height of the cartons is greater than the horizontal height of the second connecting plate 812 of the layer, the hollow dividing plate 4 is placed on the top of the carton at the highest point, and then, the curved connecting rod 88 is pulled upward, and then the curved connecting rod 88 is rotated, and finally the insertion tube structure 89 is inserted into the corresponding tube body insertion hole 6, until the four insertion tube structures 89 are correspondingly inserted into the four The tube body is inserted into the hole 6, and then the vacuum equipment is used to extract the gas inside the equipment through the vacuum channel 7. Under the action of the negative pressure of the gas, the piston body 86 will drive the hollow partition plate 4 to move downward. At this time, it should be noted: according to the normal pressure of the transported carton, the vacuum pressure value at this time is controlled so that the pressure value is close to but less than the pressure strength that the carton normally withstands. When the negative pressure of the gas below the piston body 86 reaches this range, the vacuum equipment is turned off, and then the lower threaded sleeve 91 and the upper threaded sleeve 93 are rotated respectively, and the upper threaded sleeve 93 is made to contact the bottom end of the longitudinal resistance rod 98, and then the No. 2 coil spring 94 is compressed.

[0037] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
