Description

Technical Field

[0001] The utility model relates to the technical field of printed matter production equipment, in particular to an automatic stacking device for packaging paper shells. Background Art

[0002] The automatic palletizing device can be used in conjunction with the printing device and defect detection device of the packaging paper shells. It can stack the neatly arranged packaging paper shells output from the printing device and the defect detection device according to a certain quantity, thereby facilitating the storage and sale of the packaging paper shells. The steps of palletizing the packaging paper shells can be roughly summarized as box loading, stacking, shifting, and unpalletizing. The existing palletizing device can already realize intelligent automatic palletizing, solving the problems of low efficiency and high labor intensity in traditional manual palletizing. At this stage, the improvement of the automatic palletizing device focuses on how to improve the quality and efficiency of palletizing.

[0003] Based on the above situation, in the prior art, a patent with announcement number CN215946296U discloses a double-station automatic stacking device, which includes a conveyor belt. A paper receiving working platform for receiving sheet-like packaging paper shells is arranged at the discharge port of the conveyor belt in the frame. The paper receiving working platform can be raised and lowered. Left and right aligned cardboards that can move in alignment are arranged on both sides of the paper receiving working platform. A front aligned cardboard is arranged on the side of the paper receiving working platform close to the conveyor belt, and a rear aligned cardboard is arranged on the side of the paper receiving working platform away from the conveyor belt. The rear aligned cardboard can move back and forth to achieve aligned paper. The paper patting board can be adjusted according to the size of the carton, and is suitable for carton products of different sizes. The product has good adaptability to the machine. The paper patting frequency of the paper aligning board is adjustable and controllable. The paper receiving work platform moves up and down reciprocatingly when working. When the automatic stacking device is in working state, the paper receiving work platform first rises to the position of the conveyor belt discharge port, and then slowly descends while receiving the paper. When the stacked paper reaches the preset number, the paper receiving work platform stops stacking the paper, and then directly descends to the discharge work frame, and then the stacked paper is pushed from the paper receiving work platform to the discharge work table by the push fork cylinder, and then the paper receiving work platform repeats the above process in reverse, and reaches the conveyor belt discharge port again, thus forming a complete work process.

[0004] However, the automatic stacking device in the above patent still has shortcomings. The working efficiency of the automatic stacking device needs to be improved. After stacking a preset number of papers each time, the paper receiving working platform needs to be lowered to the discharging working frame, and then the paper is pushed by the pushing fork cylinder, and then the paper receiving working platform is reset. The reciprocating process of descending, pushing and resetting takes a certain amount of time. During this reciprocating process, the paper cannot continue to be stacked. When processing a large amount of paper, this time consumption will accumulate, thereby affecting the overall working efficiency of the equipment. Utility Model Content

DETAILED DESCRIPTION

[0023] like Figures 1 to 6As shown, the utility model provides a technical solution: an automatic stacking device for packaging paper shells, comprising a frame 1, the frame 1 is connected with a switching mechanism 2, a paper aligning mechanism 3, a paper discharging mechanism 4 and a paper blocking mechanism 5, a paper inlet 13 is provided on the front side of the frame 1, the paper blocking mechanism 5 is arranged in the paper inlet 13, the paper discharging mechanism 4 is arranged outside the frame 1, the paper discharging mechanism 4 is arranged below the paper aligning mechanism 3, the switching mechanism 2 and the paper aligning mechanism 3 are arranged inside the frame 1, the switching mechanism 2 comprises a first rotating component 21, a second rotating component 22 and a chain 23, The first rotating component 21 and the second rotating component 22 are arranged in parallel up and down, and the first rotating component 21 and the second rotating component 22 are connected by a chain 23. The chain 23 is connected to a plurality of mounting plates 25, and the mounting plates 25 are connected to a freely retractable paper receiving component 28. The chain 23 can drive the paper receiving component 28 to move up and down in a circular motion through the mounting plates 25. The paper aligning mechanism 3 includes a symmetrically arranged left paper aligning component 33 and a right paper aligning component 34. The left paper aligning component 33, the right paper aligning component 34 and the paper receiving component 28 enclose a paper aligning station 14.

[0024] The utility model enables the L-shaped paper receiving board 283 in the paper aligning station 14 to switch cyclically through the coordinated operation of the switching mechanism 2, the paper aligning mechanism 3, the paper discharging mechanism 4 and the paper blocking mechanism 5, thereby reducing the waiting time between two stacking of packaging paper shells and improving the overall working efficiency of the equipment. The L-shaped paper receiving board 283 cooperates with the left paper aligning component 33 and the right paper aligning component 34, and the left paper aligning component 33 and the right paper aligning component 34 gently tap the corresponding sides of the stacked packaging paper shells, so that the packaging paper shells entering the paper aligning station 14 can be automatically stacked neatly.

[0025] It should be noted that the utility model is suitable for stacking packaging paper shells arranged in a fish scale shape. At the same time, the utility model needs to be used in conjunction with a conveyor belt, which needs to be installed in the paper inlet 13 through a U-shaped plate 12 and placed directly below the paper blocking mechanism 5.

[0026] As a preferred embodiment of the present invention, Figure 1 , Figure 2 and Figure 5 As shown, the top surface of the frame 1 is provided with an adjustment window 11 connected to the inside of the frame 1, and the adjustment window 11 is placed directly above the paper aligning station 14 and the paper aligning mechanism 3. The front side of the frame 1 is provided with a U-shaped plate 12 connected to the frame 1, and the U-shaped plate 12 is surrounded by the periphery of the paper feed port 13, and the inner side of the U-shaped plate 12 is connected to a photoelectric counter 15.

[0027] The adjustment window 11 is used to adjust the positions of the left paper aligning component 33 and the right paper aligning component 34 of the paper aligning mechanism 3 in the paper aligning station 14. The user can directly push the left paper aligning component 33 and the right paper aligning component 34 to slide on the support rod 31 through the adjustment window 11, thereby adjusting the distance between the left paper aligning component 33 and the right paper aligning component 34. In addition, because the adjustment window 11 is located directly above the paper aligning station 14, the user can observe the stacking of the packaging paper shells in the paper aligning station 14 through the adjustment window 11.

[0028] The U-shaped plate 12 is an external plate of the frame 1, which is used to place the discharge end of the conveyor belt for conveying packaging paper shells. The photoelectric counter 15 connected to the inner wall of the U-shaped plate 12 is used to count the stacked packaging paper shells. When installing the conveyor belt, the discharge end of the conveyor belt should be at the paper inlet 13 and placed directly below the paper stop mechanism 5, so that when the paper stop inclined plate 54 of the paper stop mechanism 5 falls and approaches the conveyor belt, the stacking of the packaging paper shells can be stopped. At the same time, the installation position height of the photoelectric counter 15 should be greater than the bearing surface of the conveyor belt to ensure that the photoelectric counter 15 can sense the paper on the bearing surface of the conveyor belt.

[0029] As another preferred embodiment of the present invention, Figures 2 to 4 As shown, the first rotating component 21 includes a first rotating shaft 212 and a first sprocket 211 symmetrically arranged at the left and right ends of the first rotating shaft 212, the second rotating component 22 includes a second rotating shaft 222 and a second sprocket 221 symmetrically arranged at the left and right ends of the second rotating shaft 222, the chain 23 connects the second sprocket 221 and the first sprocket 211 on the same side, the chain 23 can mesh and rotate with the second sprocket 221 and the first sprocket 211, the side of the chain 23 away from the first sprocket 211 is connected to a plurality of mounting plates 25, the rear side surface of the mounting plate 25 is symmetrically connected with a clamping groove 26 that can be engaged with the chain 23, the left and right sides of the chain 23 are respectively connected with connecting columns 27, the connecting column 27 passes through the groove wall on the corresponding side of the clamping groove 26, and one end of the first rotating shaft 212 is connected to the driving motor 24.

[0030] The switching mechanism 2 is used to align the paper receiving component 28 in the paper station 14 for switching. The first rotating component 21 and the second rotating component 22 are arranged in parallel up and down. The first rotating component 21 and the second rotating component 22 are transmitted through a chain 23. One end of the first rotating shaft 212 is connected to the power output shaft of the driving motor 24 through a coupling. When the switching mechanism 2 is working, the driving motor 24 drives the first rotating shaft 212 to rotate, and the first rotating shaft 212 drives the first sprocket wheels 211 at its left and right ends to rotate. The first sprocket wheel 211 drives the second sprocket wheel 221 to rotate through the chain 23, and the second sprocket wheel 221 drives the second rotating shaft 222 to rotate together When the chain 23 rotates, the chain 23 drives the mounting plate 25 to rotate together. The paper receiving component 28 is installed on the mounting plate 25. The paper receiving component 28 follows the mounting plate 25 and performs a circular up and down circular motion under the drive of the chain 23, thereby realizing the cyclic switching of the paper receiving component 28 in the paper aligning station 14. When the L-shaped receiving paper board 283 of the paper receiving component 28 stacks a specified number of packaging paper shells, the chain 23 drives the L-shaped receiving paper board 283 of the paper receiving component 28 to leave the paper aligning station 14 through the mounting plate 25, and at the same time makes the L-shaped receiving paper board 283 of the next paper receiving component 28 enter the paper aligning station 14 to stack the next packaging paper shell.

[0031] In the process of stacking the packaging paper shells in the paper aligning station 14, the L-shaped paper connecting paper 283 is driven by the chain 23 to slowly move downward, and the moving speed needs to match the stacking speed of the packaging paper shells. The spacing of the mounting plate 25 on the chain 23 should be the same as the distance from the lower surface of the left paper aligning paper 332 to the upper surface of the bottom plate 43 of the paper discharge mechanism 4. Therefore, driven by the chain 23, when the current L-shaped paper connecting paper 283 in the paper aligning station 14 moves downward to the position of the paper pushing rod 44, the next L-shaped paper connecting paper 283 can just enter the paper aligning station 14, thereby realizing the cyclic switching and connection of the L-shaped paper connecting paper 283 in the paper aligning station 14.

[0032] The L-shaped paper receiving paper 283 is driven by the chain 23 through the mounting plate 25 to enter the paper aligning station 14. When the mounting plate 25 is in a horizontal state, the telescopic rod of the first telescopic electric cylinder 281 is extended, and the L-shaped paper receiving paper 283 is pushed horizontally into the paper aligning station 14 through the fixed rod 282. At this time, the front end inclined surface of the L-shaped paper receiving paper 283 is close to the paper inlet 13 and is located below the discharge end of the conveyor belt.

[0033] It should be noted that the chain 23 is a prior art. Usually, the chain 23 is assembled from chain plates, pins, and bushings. The fixing between the mounting plate 25 and the chain 23 is achieved through a connecting column 27. The connecting column 27 is welded to the chain plate of the chain 23. The connecting column 27 passes through the groove wall on the corresponding side of the locking groove 26, and then is fixed by welding, so that the position of the mounting plate 25 on the chain 23 is fixed, and when the chain 23 moves, it can drive the mounting plate 25 to move together.

[0034] As another preferred embodiment of the present invention, Figure 2 and Figure 3 As shown, the mounting plate 25 is correspondingly mounted with a paper receiving component 28, and the paper receiving component 28 includes a plurality of first telescopic electric cylinders 281, a plurality of fixed rods 282 and a plurality of L-shaped paper receiving papers 283, wherein the first telescopic electric cylinders 281 are connected to the fixed rods 282, the L-shaped paper receiving papers 283 are equidistantly arranged, and adjacent L-shaped paper receiving papers 283 are connected via fixed rods 282.

[0035] The paper receiving component 28 is used to receive paper in the paper aligning station 14. A paper receiving component 28 is installed on each mounting plate 25 of the switching mechanism 2. Two adjacent L-shaped paper receiving papers 283 are connected by a fixing rod 282. The fixing rod 282 and the L-shaped paper receiving paper 283 are fixedly connected by welding. The telescopic rod of the first telescopic electric cylinder 281 is connected to the fixing rod 282, and the cylinder body of the first telescopic electric cylinder 281 is installed on the mounting plate 25.

[0036] As another preferred embodiment of the present invention, Figure 2 , Figure 5 and Figure 7 As shown, the paper aligning mechanism 3 also includes a support rod 31 and a sliding sleeve 32 sleeved on the outside of the support rod 31, both ends of the support rod 31 are respectively connected to the frame 1, the left paper aligning component 33 includes a second telescopic electric cylinder 331 and a left paper aligning board 332 connected to the second telescopic electric cylinder 331, and the right paper aligning component 34 includes a third telescopic electric cylinder 341 and a right paper aligning board 342 connected to the third telescopic electric cylinder 341, the tops of the second telescopic electric cylinder 331 and the third telescopic electric cylinder 341 are respectively connected to the sliding sleeve 32, the second telescopic electric cylinder 331 and the third telescopic electric cylinder 341 can be respectively adjusted on the support rod 31 through the sliding sleeve 32, the left paper aligning board 332 and the right paper aligning board 342 are together enclosed with the L-shaped connecting board 283 to form a paper aligning station 14, the support rod 31 is provided with jacks 35 equidistantly distributed along the length direction, and the sliding sleeve 32 is provided with a movably pluggable plug-in pin 36 that can cooperate with the jack 35.

[0037] The two ends of the support rod 31 are respectively connected to the frame 1, so that the whole of the paper aligning mechanism 3 is horizontally arranged above the paper discharge mechanism 4, the left paper aligning paper board 332 and the right paper aligning paper board 342 are arranged opposite to each other, and the left paper aligning component 33 and the right paper aligning component 34 are fixed to the support rod 31 through a sliding sleeve 32, and the sliding sleeve 32 can slide freely on the support rod 31, so that the distance between the left paper aligning component 33 and the right paper aligning component 34 is adjustable, and the latch 36 is used to fix the left paper aligning component 33 and the right paper aligning component 34. The paper aligning component 34 is positioned on the support rod 31, and the pin 36 penetrates through the side wall of the sliding sleeve 32 and is then vertically inserted into the insertion hole 35 on the surface of the support rod 31, thereby fixing the left paper aligning component 33 and the right paper aligning component 34 on the support rod 31. When the paper aligning work is performed, the second telescopic electric cylinder 331 drives the left paper aligning paper board 332 and the third telescopic electric cylinder 341 drives the right paper aligning paper board 342 to reciprocate and tap the corresponding sides of the stacked packaging paper shells, so that the packaging paper shells are stacked neatly.

[0038] As another preferred embodiment of the present invention, Figure 1 ,and Figure 2 As shown, the paper discharging mechanism 4 includes a receiving paper board 41, a fourth telescopic electric cylinder 42, a bottom plate 43 and a plurality of paper pushing rods 44. The receiving paper board 41 is connected to the frame 1, the fourth telescopic electric cylinder 42 is arranged on the lower surface of the receiving paper board 41, the bottom plate 43 is connected to the fourth telescopic electric cylinder 42, and the paper pushing rods 44 are equidistantly arranged on the surface of the bottom plate 43.

[0039] The paper discharge mechanism 4 is used to push the packaging paper shells stacked on the L-shaped receiving paper board 283 of the paper receiving component 28 to the surface of the receiving paper board 41. When setting, the spacing of the paper pushing rods 44 should be staggered with the installation position of the L-shaped receiving paper board 283. When the paper receiving component 28 descends and approaches the paper discharge mechanism 4, the paper pushing rods 44 of the paper discharge mechanism 4 should be placed between adjacent L-shaped receiving paper boards 283, thereby preventing the L-shaped receiving paper boards 283 from colliding with the paper pushing rods 44 during the descending process. The cylinder body portion of the fourth telescopic electric cylinder 42 is installed on the lower surface of the receiving paper board 41, and the telescopic rod of the fourth telescopic electric cylinder 42 is connected to the bottom plate 43, so that the fourth telescopic electric cylinder 42 can drive the paper pushing rod 44 to reciprocate through the bottom plate 43.

[0040] When the paper discharge mechanism 4 is in operation, the chain 23 first drives the paper receiving component 28 in the paper aligning station 14 to move downward through the mounting plate 25. During the downward movement, the paper pushing rod 44 is vertically inserted from the rear side of the stacked packaging paper shell into between the two connected L-shaped receiving paper boards 283. Then, the telescopic rod of the fourth telescopic electric cylinder 42 is retracted, and at the same time, the paper pushing rod 44 is driven by the bottom plate 43 to horizontally push the stacked packaging paper shell in the direction of the receiving paper board 41, pushing the stacked packaging paper shell away from the L-shaped receiving paper board 283 and onto the surface of the receiving paper board 41, thereby realizing the paper discharge pushing process of the stacked packaging paper shell. Then, the telescopic rod of the first telescopic electric cylinder 281 of the paper receiving component 28 is retracted, and the L-shaped receiving paper board 283 is driven to be retracted and reset through the fixed rod 282.

[0041] As another preferred embodiment of the present invention, Figure 1 and Figure 5 As shown, the paper blocking mechanism 5 includes a mounting rod 51, a fixing seat 52, a fifth telescopic electric cylinder 53 and a paper blocking inclined plate 54. Both ends of the mounting rod 51 are placed in the paper feed port 13 and connected to the frame 1. The fixing seat 52 is fixedly sleeved on the outside of the mounting rod 51. The bottom surface of the fixing seat 52 is connected to the bottom of the fifth telescopic electric cylinder 53. The telescopic rod of the fifth telescopic electric cylinder 53 is connected to the paper blocking inclined plate 54.

[0042] The paper blocking mechanism 5 is installed as a whole in the paper feed port 13. The paper blocking mechanism 5 is used to prevent the packaging paper shells on the conveyor belt from continuing to move and entering the paper aligning station 14 by driving the fifth telescopic electric cylinder 53 to press down the paper blocking inclined plate 54 when the L-shaped paper receiving paper 283 of the next paper receiving component 28 starts to enter the paper aligning station 14 until it completely enters. When a sufficient number of packaging paper shells are stacked on the L-shaped paper receiving paper 283, the conveyor belt stops conveying the packaging paper shells, and then the telescopic rod of the fifth telescopic electric cylinder 53 pushes the paper blocking inclined plate 54 downward to press the packaging paper shells on the discharge end of the conveyor belt to prevent the packaging paper shells from continuing to move due to inertia and entering the paper aligning station 14.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
