Description

Technical Field

[0001] The present invention relates to a cartoning machine. Background Art

[0002] A cartoning machine is a mechanical device used to pack items into cartons. The general cartoning process of a cartoning machine is as follows: the carton suction device sucks the flat cartons from the carton hopper and places them on the grid conveyor. After being placed on the grid conveyor, the cartons are in an open state, but the bottom of the cartons is not closed. Before the items are loaded into the cartons, the bottom of the cartons needs to be closed. Figure 5 As shown, the bottom of a typical paper box has four sides: the lower bottom (H3), the left and right side bottoms (H1 and H2), and the upper bottom (H4). To close the bottom of the box, the lower bottom (H3) must first be raised, then the left and right side bottoms (H1 and H2) must be brought inward, and finally, the front edge of the upper bottom (H4) must be buckled against the inside of the lower bottom (H3), completing the closure of the box. Existing cartoning machines use a pneumatic cylinder to push a push rod to raise the lower bottom, and a pneumatic cylinder to push a pressure rod to press the upper bottom against the inside of the lower bottom. However, the cylinder is prone to malfunction, and the carton must stop on the grid conveyor to wait for the cylinder to operate. This results in low packaging efficiency and unstable operation.

[0020] like Figure 1 As shown, this fully automatic cartoning machine includes a base 1 and a grid conveyor 8. The carton H is conveyed forward on the grid conveyor 8 to complete the processes of closing the bottom of the carton and packaging the materials.

[0021] like Figure 5As shown, the bottom of this paper box H consists of four panels: the lower panel H3, the left panel H1, the right panel H2, and the upper panel H4. The order for closing the bottom of the box is: first, raise the lower panel H3, then bring the left and right panels H1 and H2 inward, and finally, buckle the front edge of the upper panel H4 onto the inside of the lower panel H3. This completes the bottom of the box.

[0022] In order to close the bottom of the carton, the present invention is provided with a lower bottom guide rod 2 on one side of the grid conveying device 8, as shown in FIG. Figure 2 As shown, the front end of the lower bottom guide rod 2 has a gradually upward lower guide slope 20. When the carton H moves forward, the lower guide slope 20 of the lower bottom guide rod 2 gradually lifts the lower bottom surface H3 of the carton H. A box bottom closing mechanism 3 is provided on one side of the lower bottom guide rod 2. Figure 4 As shown, the box bottom closing mechanism 3 includes a rotating shaft 30 and a closing member connected to the rotating shaft 30, the closing member having a first action end 31 and a second action end 32, the rotating shaft 30 is connected to the closing power source for driving the rotating shaft 30 to rotate, the rotating shaft 30 rotates to drive the closing member to rotate, the first action end 31 of the closing member can close the lower bottom surface H3 of the carton H after being lifted inward, as the carton H moves forward, the rotating shaft 30 drives the closing member to rotate, and when it rotates 180 degrees, the second action end 32 of the closing member just acts on the right bottom surface H2 of the carton H, so that the right bottom surface H2 also closes inward; when the box bottom is closed A side bottom guide rod 4 is provided in front of the mechanism 3. As the carton H moves forward, the side bottom guide rod 4 acts on the left bottom surface H1 of the carton H, so that the left bottom surface H1 of the carton H also closes inward; an upper bottom guide rod 5 is provided above the side bottom guide rod 4, and the front end of the upper bottom guide rod 5 has an upper guide slope 50 that gradually declines. As the carton H continues to move forward, the upper guide slope 50 of the upper bottom guide rod 5 gradually presses the upper bottom surface H4 of the carton H downward; a box bottom buckling mechanism 6 is provided on the side of the upper bottom guide rod 5, and the box bottom buckling mechanism 6 buckles the front end of the upper bottom surface H4 of the carton H after being pressed downward to the inner side of the lower bottom surface H3.

[0023] like Figure 3As shown, the bottom buckle mechanism 6 of the box includes a support 67 and a buckle bottom plate 60, the buckle bottom plate 60 is connected to the mounting seat 68, the mounting seat 68 is installed on the first connecting shaft 61 and the second connecting shaft 62, the lower end of the first connecting shaft 61 is rotatably connected to the first connecting member 63, the lower end of the second connecting shaft 62 is rotatably connected to the second connecting member 64, the first connecting member 63 is connected to the first transmission shaft 65, the first transmission shaft 65 is staggered with the first connecting shaft 61 in the axial direction, and the second connecting shaft is staggered with the first connecting shaft 61 in the axial direction. Component 64 is connected to the second transmission shaft 66, the second transmission shaft 66 and the second connecting shaft 62 are staggered in the axial direction, the first transmission shaft 65 is connected to the first synchronous wheel 651, and the second transmission shaft 66 is connected to the second synchronous wheel 661. A synchronous belt 69 is wound around the first synchronous wheel 651 and the second synchronous wheel 661. The first transmission shaft 65 and the second transmission shaft 66 are both rotatably mounted on the support 67, and the first transmission shaft 65 is transmission-connected to the snap-fit ​​power source that drives the first transmission shaft 65 to rotate.

[0024] The working principle of the box bottom buckle mechanism 6 is as follows: the buckle power source drives the first transmission shaft 65 to rotate, and the first transmission shaft 65 drives the second transmission shaft 66 to rotate synchronously through the synchronous belt 69, so that the first transmission shaft 65 drives the first connecting shaft 61 to rotate around the axis of the first transmission shaft 65 through the first connecting member 63, and the second transmission shaft 66 drives the second connecting shaft 62 to rotate around the axis of the second transmission shaft 66 through the second connecting member 64. Since the mounting seat 68 is mounted on the first connecting shaft 61 and the second connecting shaft 62, and the buckle bottom plate 60 is connected to the mounting seat 68, the buckle bottom plate 60 is as shown Figure 6 The motion trajectory shown moves from Figure 6 It can be seen that the buckle bottom plate 60 has two movement directions: left and right movement and front and back movement. When the buckle bottom plate 60 moves to the right (such as Figure 6 As shown in the right direction, the buckle bottom plate 60 presses the upper bottom surface H4 of the paper box H inward and buckles the front edge of the upper bottom surface H4 against the inner side of the lower bottom surface H3, so that the bottom of the paper box H is closed. Figure 6 The upward direction shown in FIG4 ), so that the carton H can move forward together with the carton H, so that the carton H can keep moving forward without stopping, thereby significantly improving the packaging efficiency.

[0025] The upper bottom surface H4 of the paper box H is generally kept level with the upper surface of the box body. However, if some paper boxes H are large, the upper bottom surface H4 of the paper box H may droop, affecting the closing of the left bottom surface H1 and the right bottom surface H2 of the paper box H. To this end, the present invention provides an upper bottom support rod 7 above the lower bottom guide rod 2. Figure 2As shown, the front end of the upper bottom support rod 7 has a gradually upward guiding support surface 70. When the carton H is conveyed forward, the guiding support surface 70 of the upper bottom support rod 7 gradually lifts the upper bottom surface H4 of the carton H upward, thereby ensuring that the left bottom surface H1 and the right bottom surface H2 of the carton H can be smoothly closed.

[0026] The closing member can be a single rod connected to the rotating shaft 30, but a single rod cannot be adjusted. To enable adjustment, the closing member of the present invention includes a connecting base 33, a first actuating rod, and a second actuating rod. The connecting base 33 is connected to the rotating shaft 30, and the first actuating rod and the second actuating rod are adjustably mounted at either end of the connecting base 33 (adjustable via slots and bolts). The outer end of the first actuating rod is the first actuating end 31, and the outer end of the second actuating rod is the second actuating end 32. Because the positions of the first and second actuating rods on the connecting base 33 are adjustable, the points of application of the first and second actuating ends 31 and 32 can be adjusted.

[0027] To facilitate adjustment of the vertical position of the buckle bottom plate 60, a mounting base 68 is slidably mounted on the first connecting shaft 61 and the second connecting shaft 62. An adjustment support 601 is connected to the upper ends of the first connecting shaft 61 and the second connecting shaft 62. A rotatable adjustment screw 600 is mounted on the adjustment support 601, and the mounting base 68 is threadedly connected to the adjustment screw 600. When the height of the buckle bottom plate 60 needs to be adjusted, the adjustment screw 600 is simply rotated, and the mounting base 68 moves up and down, thereby adjusting the position of the buckle bottom plate 60.

[0028] In order to keep the synchronous belt 69 in a taut state, the present invention is provided with a tensioning wheel 33 on the support 67, and the tensioning wheel 33 acts on the synchronous belt 69. Through the effect of the tensioning wheel 33, the synchronous belt 69 just can be in a taut state.

[0029] like Figure 7 As shown, the grid conveying device 8 includes a plurality of conveying grid plates 81 (the grid conveying device 8 is a prior art and also includes a conveying chain, and the conveying grid plates 81 are connected to the conveying chain), as shown in FIG. Figure 8 As shown, there is a lower grid spacing 82 between two adjacent conveying grids 81, and the paper box H is transported in the lower grid spacing 82. However, some paper boxes are relatively high, and the conveying grid 81 of the grid conveying device 8 only acts on the lower side of the paper box H, such as Figure 8 As mentioned above, if the conveying speed of the grid conveying device 8 is fast, the paper box H will tilt due to inertia, resulting in the subsequent box closing device being unable to close the box cover of the paper box.

[0030] In order to prevent the carton H from tilting during the conveying process, the present invention is provided with a grid box supporting device 9 above the grid conveying device 8. Figure 7As shown, the grid box supporting device 9 includes a box supporting belt 90, a box supporting power source and a plurality of box supporting grids 91. The plurality of box supporting grids 91 are connected to the box supporting belt 90 (the box supporting belt 90 can be replaced by a chain, and the two are equivalent). The box supporting power source can drive the box feeding belt 90 to rotate, as shown in FIG. Figure 9 As shown, there is an upper grid plate spacing 92 between two adjacent support box grid plates 91, and the upper grid plate spacing 92 is equal to the lower grid plate spacing 82.

[0031] During operation, the carton H is in the lower grid spacing 82 and is conveyed forward. Since the upper grid spacing 92 is equal to the lower grid spacing 82 and the linear speed is the same, when the carton H enters under the grid conveying device 8, the carton H enters the upper grid spacing 92. In this way, the box supporting grid 91 acts on the upper part of the carton, and the conveying grid 81 acts on the lower part of the carton. The box supporting grid 91 and the conveying grid 81 cooperate up and down to push the carton H forward. In this way, no matter how high the carton is or how fast the conveying speed is, the carton will not tilt during conveying, so that the carton can always be conveyed upright, ensuring the subsequent smooth closing of the carton.

[0032] Finally, it is worth mentioning that the power source for the grille conveying device 8 and the grille supporting device 9 can be the same power source or two independent power sources; the power source for closing the box bottom closing mechanism and the power source for locking the box bottom locking mechanism can be the same power source or two independent power sources. In fact, the grille conveying device 8, the grille supporting device 9, the box bottom closing mechanism 3, and the box bottom locking mechanism 6 can all use a single power source.
