Description

Technical Field

[0001] This invention relates to the field of packaging equipment technology, and in particular to an automatic box packing machine for complex gift boxes. Background Technology

[0002] A case packer is an automated device primarily used to pack cardboard boxes into corresponding product packaging. This equipment is widely used in various industries, such as food and beverage, health products, and cosmetics, where precise measurement, sorting, coding, and packaging of goods are required.

[0003] However, existing technologies still have shortcomings. For example, a side-entry gift box packing machine with patent number CN202121745080.5 includes a box body and a roller logistics line, as well as a box picking mechanism, a side-blocking assembly, and a box pushing assembly. The box picking mechanism includes a mounting plate fixed to one side of the roller logistics line, a first rotating shaft disposed between the mounting plates, a first servo motor fixed to the side of the mounting plate, a rotating arm fixed to the first rotating shaft, and a box-flipping frame fixed to the rotating arm. The box pushing assembly includes a box-stacking platform fixed above the mounting plate. The beneficial effect of this utility model is that the box picking mechanism automatically rotates the box body on the roller logistics line by 90°, with the opening facing the box pushing assembly. A specified number of gift boxes are pushed into the box body through the box pushing plate. The box body is rotated 90° again to return to the roller logistics line to complete the packing. This improves the packing and shipping speed of gift boxes and solves the problem of product stacking.

Detailed Implementation

[0035] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0036] Example 1: Reference Figure 1 and Figure 2 An automatic gift box packing machine includes: a workbench 1, a roller conveyor 2, a lead screw 3, and a packing mechanism 4. The workbench 1 is equipped with the roller conveyor 2 and a mounting frame. The lead screw 3 is longitudinally arranged above the workbench 1. One end of the lead screw 3 is rotatably connected to the mounting frame, and the other end of the lead screw 3 is connected to the output end of a servo motor on the mounting frame. The packing mechanism 4 is threadedly connected to the lead screw 3. The packing mechanism 4 is slidably connected to the mounting frame, and the output end of the packing mechanism 4 is set towards the roller conveyor 2.

[0037] The principle behind the above scheme is as follows:

[0038] Start the roller conveyor 2. The specific model of roller conveyor 2 is XS-1041A. Roller conveyor 2 drives the box to move downwards to the lead screw 3. The servo motor rotates forward to drive the boxing mechanism 4 to move upwards to the roller conveyor 2. After the boxing mechanism 4 moves to the top of the box, the boxing mechanism 4 places the gripped product into the box.

[0039] The beneficial effects of the above scheme are as follows: by setting a servo motor to drive the lead screw 3 to rotate, the lead screw 3 is set longitudinally above the worktable 1, and the other end of the lead screw 3 is rotatably connected to the mounting bracket, the displacement between parts is reduced, and the space occupied by the device in the work site is saved; at the same time, the rationality of the device design is improved.

[0040] Example 2: Reference Figure 2 , Figure 3 and Figure 14 The packing mechanism 4 includes: a mounting base 5, a drive plate 6, a pull rod 7, and a gripping plate 8. The lead screw 3 is threadedly connected to the slide block, and the slide block is slidably connected to the mounting frame. A lifting cylinder is mounted on the slide block, and the output end of the lifting cylinder faces the roller conveyor 2. The mounting base 5 is mounted on the output end of the lifting cylinder, and a cylinder is mounted on the mounting base 5. The drive plate 6 is mounted on the output end of the cylinder, and the drive plate 6 is located below the mounting base 5 and faces the roller conveyor 2. The top end of the pull rod 7 is hinged to the side wall of the drive plate 6, the bottom end of the pull rod 7 is hinged to the inner wall of the gripping plate 8, and the top end of the gripping plate 8 is hinged to the side wall of the mounting base 5.

[0041] The principle behind the above scheme is as follows:

[0042] When the product needs to be clamped, the output of the servo motor reverses, causing the lead screw to reverse. Guided by the mounting frame, the slide moves above the product. The lifting cylinder is activated, and its output drives the mounting base 5 downward. Simultaneously, the cylinder starts, and its output drives the drive plate 6 downward. The top of the pull rod 7 moves downward, and the bottom of the pull rod 7 moves away from the cylinder output. At the same time, the gripping plate 8 rotates relative to the mounting base 5, and multiple gripping plates 8 open, ready to grip the product. The cylinder is activated again, and its output drives the drive plate 6 upward. The drive plate 6 drives the top of the pull rod 7 upward, and the bottom of the pull rod 7 rotates the gripping plate 8 relative to the mounting base 5, gripping the product. Simultaneously, the lifting cylinder is activated, causing the mounting base 5 to move upward. The output of the servo motor rotates forward, causing the lead screw 3 to rotate forward. The slide is guided by the mounting frame to the top of the roller conveyor 2, thus placing the product in the box.

[0043] The beneficial effects of the above scheme are as follows:

[0044] The lifting cylinder can control the height of the mounting base 5 and the gripping plate 8, thereby completing the gripping of the product. The lifting cylinder increases the movement stroke of the mounting base 5, avoiding collision with the product before the gripping plate 8 grips the product, thus improving the rationality of the device. At the same time, it further utilizes the internal space of the device, and the arrangement between the components is more compact, further improving the working efficiency of the device.

[0045] Example 3: Reference Figures 1-4 It also includes: a conveyor belt mechanism; the conveyor belt mechanism is set on the workbench 1 and is set parallel to the roller conveyor 2. The conveyor belt mechanism is set below the lead screw 3. Multiple material distribution plates 9 are equidistantly arranged on the workbench 1. The bottom end of the material distribution plate 9 slides and rubs against the conveyor belt mechanism. The output end of the material distribution plate 9 is set towards the mounting frame.

[0046] The principle behind the above scheme is as follows:

[0047] The conveyor belt mechanism guides individual products to the distribution plate 9. The two distribution plates 9 form a guide groove. Each guide groove can control the length of the input product. Multiple guide grooves cooperate with each other to control the width of the product. After the product is assembled, the gripping plate 8 grips and moves the product.

[0048] The beneficial effects of the above scheme are as follows:

[0049] The material distribution plate 9 works in conjunction with the conveyor belt mechanism to control the length and width of the products. At the same time, the products guided by the material distribution plate 9 have a high degree of parallelism and are neatly stacked, making it easy for the gripping plate 8 to grip them.

[0050] Example 4: Reference Figures 1-7 The workbench 1 has a slide rail end on its side wall. The slide rail is located above the roller conveyor 2. The other end of the slide rail is located above the second mounting frame. The second mounting frame is connected to the side of the workbench 1. The second mounting frame is equipped with a storage box 10 and a third conveyor belt mechanism. Each side of the storage box 10 has a guide groove. A baffle 33 is slidably connected in the guide groove. One end of the baffle 33 is placed inside the storage box 10. The end of the baffle 33 outside the storage box 10 is connected to the output end of the switch cylinder 36. The switch cylinder 36 is installed on the side wall of the storage box 10. The output end of the storage box 10 faces the third conveyor belt mechanism. A feeding slider is slidably connected on the slide rail. A motor is installed on the feeding slider. The guide wheel installed at the output end of the motor is in frictional cooperation with the slide rail. A suction cup 11 is installed at the bottom of the feeding slider. The suction end of the suction cup 11 faces the roller conveyor 2. The top of the suction cup 11 is connected to a vacuum pump through a pipe. The specific model of the vacuum pump is: 2XZ type.

[0051] The principle behind the above scheme is as follows:

[0052] After the product is packed, it is carried to the bottom of the slide rail by the roller conveyor 2. The output end of the switching cylinder 36 moves outward from the storage box 10, causing the baffle 33 to move outward. At the same time, the pad in the storage box 10 is released onto the third conveyor belt mechanism. The switching cylinder 36 drives the baffle 33 to reset. The two baffles 33 cooperate to block the remaining pad in the storage box 10. The pad moves under the suction cup 11 guided by the third conveyor belt mechanism. The vacuum pump starts, the air pressure on the top surface of the pad decreases, and the pad is attracted to the suction cup 11. The motor starts, and the output end of the motor drives the guide wheel to rub against the slide rail, and drives the suction cup 11 and the pad to move. After the pad moves to the top of the box containing the product, the vacuum pump is turned off to release the pad.

[0053] The beneficial effects of the above scheme are as follows:

[0054] The suction cup 11 works in conjunction with the slider driven by the motor and guide wheel to move the pad. The pad is released on the top of the product. The pad can form a buffer between the box and the product after packing to prevent product vibration from causing damage. The baffle 33 is set to release and block the pad in the storage box 10 to prevent the pad from falling on the third conveyor belt mechanism.

[0055] Example 5: Reference Figure 8 The third mounting bracket on the workbench 1 is equipped with a second servo motor 12. The output shaft of the second servo motor 12 is arranged parallel to the lead screw 3. The output shaft of the second servo motor 12 is equipped with a pressure plate. The side wall of the pressure plate has multiple intermittent grooves 13 at equal intervals.

[0056] The principle behind the above scheme is as follows:

[0057] After the box body is guided by the roller conveyor 2 to move below the output shaft of the second servo motor 12, the short cover plate on one side of the box body contacts the inner wall of one side of the intermittent trough 13 and is pressed down. The second servo motor 12 is started to rotate clockwise. The output shaft of the second servo motor 12 drives the pressure plate to rotate clockwise. The inner wall of the other side of the intermittent trough 13 contacts another short cover plate and presses it down.

[0058] The beneficial effects of the above scheme are as follows:

[0059] An intermittent groove 13 is opened on the capping plate. The rotation of the intermittent groove 13 is controlled by the rotation of the output shaft of the second servo motor 12. The two inner walls of the intermittent groove 13 press a short cap plate respectively, which simplifies the design of the capping device and improves the capping efficiency of the short cap plate.

[0060] Example 6: Reference Figure 8 and Figure 11 The third mounting bracket is equipped with a third cylinder, and the output end of the third cylinder is hinged to the bottom end of the pressure rod 14. The pressure rod 14 is rotatably connected to the third mounting bracket, and the top end of the pressure rod 14 is set towards the roller conveyor 2.

[0061] The workbench 1 is equipped with a capping cylinder 34, which is positioned facing the roller conveyor 2. The output end of the capping cylinder 34 is equipped with a pressure plate 35, which is perpendicular to the lead screw 3 in its length direction.

[0062] The principle behind the above scheme is as follows:

[0063] Guided by the roller conveyor 2, the box moves to the third cylinder. The third cylinder is started, and the output end of the third cylinder moves upward, causing the pressure rod 14 to rotate around the third mounting frame. The top of the pressure rod 14 presses the long cover plate of the box. After the pressing is completed, the output end of the third cylinder resets, driving the pressure rod 14 to reset, preparing for its next operation.

[0064] After the long cover plate is pressed, the box body is guided by the roller conveyor 2 to the bottom of the pressure plate 35. The cover cylinder 34 is started, and the output end of the cover cylinder 34 drives the pressure plate 35 to move downward to press the other long cover plate of the box body.

[0065] The beneficial effects of the above scheme are as follows:

[0066] Before pressing the short cover plate, the long cover plate is pressed first. The output end of the third cylinder is hinged to the bottom end of the pressure rod 14. The pressure rod 14 is rotatably connected to the third mounting bracket. The top of the pressure rod 14 presses the long cover plate, which improves the efficiency of the device in pressing the long cover plate.

[0067] The pressure plate 35 is set to press and cover another long cover plate to finish packaging the box. At the same time, the pressure plate 35 can slide and cooperate with the other long cover plate, so that the pressing and covering of the other long cover plate can be completed without shutting down the roller conveyor 2, reducing the number of times the roller conveyor 2 is started and stopped, and avoiding damage caused by repeated opening and closing of the roller conveyor 2.

[0068] Example 7: Reference Figure 9 and Figure 10 The workbench 1 is equipped with a guide wheel seat on its side wall. A rotating shaft is rotatably connected to the guide wheel seat. The bottom end of the rotating shaft is connected to the end of the plate. A torsion spring is installed between the top surface of the plate and the guide wheel seat. A guide wheel 15 is rotatably connected to the other end of the plate. The guide wheel 15 is located above the output end of the roller conveyor 2.

[0069] The principle behind the above scheme is as follows:

[0070] When the roller conveyor 2 guides the box, the side wall of the guide wheel 15 rolls with the box. When the volume of the box increases, the guide wheel 15 drives the end of the plate to rotate away from the worktable 1 relative to its other end. The other end of the plate drives the rotating shaft to rotate, and the torsion spring twists away from the worktable 1.

[0071] When the volume of the box decreases, the guide wheel 15 drives the end of the plate to rotate relative to its other end towards the worktable 1, the other end of the plate drives the rotating shaft to rotate, and the torsion spring to twist towards the worktable 1.

[0072] The beneficial effects of the above scheme are as follows:

[0073] The guide wheels 15 are set to roll in coordination with the box to provide centering for the box during movement; at the same time, the guide wheels 15 can guide boxes of different volumes, improving the adaptability of the device to different products during operation.

[0074] Example 8: Reference Figure 12 and Figure 13 The workbench 1 is rotatably connected to a guide shaft 16, which is parallel to the lead screw 3. A guide wheel 17 is mounted on the guide shaft 16 and is positioned above the roller conveyor 2.

[0075] The principles and beneficial effects of the above scheme are as follows:

[0076] After the box is covered, it is moved to the bottom of the guide wheel 17 by the roller conveyor 2. The top of the box is in frictional contact with the guide wheel 17 to improve the sealing effect of the cover plate on the box.

[0077] Example 9: Reference Figure 3 and Figure 14 The drive plate 6 is equipped with an air guide shell 18. The top end of the air guide shell 18 is connected to the bottom end of the air guide pipe assembly 19. The other end of the air guide pipe assembly 19 is connected to the air supply device. Each side wall of the air guide shell 18 is equipped with an auxiliary air guide pipe. The auxiliary air guide pipe is connected to the top end of the pull rod 7. The pull rod 7 has a hollow structure and multiple exhaust holes 20 are opened at the bottom end of the pull rod 7.

[0078] The principle behind the above scheme is as follows:

[0079] When the air supply device is activated, the air guide pipe assembly 19 supplies air to the air guide shell 18, the air guide shell 18 supplies air to the auxiliary air guide pipe, the auxiliary air guide pipe supplies air to the pull rod 7, and the airflow is output through the exhaust hole 20 at the bottom of the pull rod 7. The airflow can clean the roller conveyor 2, the conveyor belt mechanism and the product.

[0080] The beneficial effects of the above scheme are as follows:

[0081] The vent 20 can clean up dust accumulated on the surface of the product during movement or placement, improving the cleanliness of the packaged product and making full use of the space inside the device. Furthermore, since the air discharged from the vent 20 can cool the surface of the product, bacteria are less likely to grow on the outside of the product after cooling. The vent 20 can also cool the conveyor belt mechanism, dissipating the heat generated by the conveyor belt mechanism during long-term operation, and preventing the product from absorbing the heat emitted from the conveyor belt mechanism, which would lead to product deterioration.

[0082] Example 10: Reference Figure 14 and Figure 15 The top surface of the pull rod 7 has a guide groove 2, and an exhaust pipe 21 is slidably connected inside the pull rod 7. The bottom end of the exhaust pipe 21 has multiple second exhaust holes 22, which are concentrically arranged with the exhaust holes 20. The exhaust pipe 21 is slidably sealed with the guide groove 2. The bottom end of the drive rod 23 is hinged to the top surface of the exhaust pipe 21. The drive rod 23 is slidably connected to the bottom end of the guide post 24. The positioning block on the drive rod 23 is connected to the bottom end of the guide post 24 through a reset spring 25. The top end of the guide post 24 is installed on the bottom surface of the mounting base 5. A rubber tube 26 is longitudinally installed on the inner wall of the gripping plate 8. The top end of the rubber tube 26 is connected to the mounting hole at the bottom end of the pull rod 7. The mounting hole faces the bottom end of the exhaust pipe 21. A second rubber tube 27 is connected to the bottom end of the rubber tube 26. The second rubber tube 27 is horizontally installed on the inner wall of the gripping plate 8.

[0083] The principle behind the above scheme is as follows:

[0084] When the top of the pull rod 7 moves upward relative to the drive plate 6, the exhaust pipe 21 moves synchronously. The top of the exhaust pipe 21 drives the drive rod 23, which is hinged to it, to move upward, while compressing the return spring 25. The exhaust pipe 21 moves downward relative to the pull rod 7, and the exhaust hole 20 on the pull rod 7 closes the second exhaust hole 22. The airflow enters the rubber tube 26 through the exhaust pipe 21. By inflating the rubber tube 26, the second rubber tube 27 is inflated synchronously.

[0085] The beneficial effects of the above scheme are as follows:

[0086] During the clamping process of the gripping plate 8, the second rubber tube 27 cushions the product to prevent it from being crushed during clamping. At the same time, the expansion of the second rubber tube 27 increases the friction of the gripping plate 8 when clamping the product, preventing the product from falling during movement, improving the stability of the product during movement, and ensuring the yield rate of the product after packaging.

[0087] Example 11: Reference Figure 16 The air guide tube assembly 19 includes: an air guide tube 28, a sleeve 29, an air guide hole 30, and an auxiliary air guide tube 31. The top of the air guide shell 18 is fitted with a sleeve 29, and the bottom end of the air guide tube 28 is slidably connected inside the sleeve 29. The air guide tube 28 is inserted into the mounting base 5, and the other end of the air guide tube 28 is connected to the air supply device. A sealing plate 32 is fitted at the bottom end of the air guide tube 28. An air guide hole 30 is opened on the side wall of the air guide tube 28, and an auxiliary air guide hole is opened on the side wall of the sleeve 29. The auxiliary air guide hole and the air guide hole 30 are staggered. The top wall of the air guide hole 30 is located above the top wall of the auxiliary air guide hole. One end of the auxiliary air guide tube 31 is connected to the auxiliary air guide hole, and the other end of the auxiliary air guide tube 31 is connected to the positioning hole at the top of the air guide shell 18.

[0088] The principles and beneficial effects of the above scheme are as follows:

[0089] When the drive plate 6 moves upward, the air guide pipe 28 moves downward relative to the sleeve 29, increasing the conduction area between the air guide hole 30 and the auxiliary air guide pipe 31, thus increasing the air supply to the second rubber tube 27. When the drive plate 6 moves downward, the air guide pipe 28 moves upward relative to the sleeve 29, decreasing the conduction area between the air guide hole 30 and the auxiliary air guide pipe 31. At the same time, the second rubber tube 27 can vent air through the second exhaust hole 22 and the exhaust hole 20, preventing air accumulation in the second rubber tube 27 during refilling, which could lead to overfilling and rupture. By reducing the air pressure of the pull rod 7, the gas in the second rubber tube 27 is prevented from being unable to escape, improving the safety of the device during operation. At the same time, by making full use of the relative movement between the components, the inflation and deflation of the rubber tube 26 and the second rubber tube 27 are completed, improving the device's autonomous operation capability and practicality.

[0090] The other end of the auxiliary air guide tube 31 is connected to the positioning hole at the top of the air guide shell 18, which reduces the number of airflow guiding components and avoids interference between components when the gripping plate 8 moves.
