Detailed Implementation

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0033] Please see the appendix Figure 1-10 As shown, this embodiment provides an automatic production line for corrugated boxes, including a counting and stacking machine for producing corrugated boxes. The counting and stacking machine includes a first conveying device for inputting corrugated boxes, a counting and stacking device for counting and stacking corrugated boxes, and a second conveying device for outputting corrugated boxes. The first conveying device includes a conveying mechanism and a sliding support mechanism. The counting and stacking device includes a frame 1, a chain drive mechanism, and a lifting counting and stacking mechanism. One end of the conveying mechanism is rotatably mounted on the lifting counting and stacking mechanism, and the other end is rotatably mounted on the sliding support mechanism. The lifting counting and stacking mechanism is mounted on the frame 1 via the chain drive mechanism. One end of the second conveying device extends below the lifting counting and stacking mechanism, and the other end extends out of the lifting counting and stacking mechanism. The second conveying device is a roller conveyor 53.

[0034] In this embodiment, the corrugated cardboard boxes delivered by the vibratory waste removal machine are conveyed to the counting and stacking device via the first conveying device, and then placed on the second conveying device after being counted and stacked. The second conveying device then conveys the neatly stacked corrugated cardboard boxes, after a certain number of counts, out of the cardboard box stacking area of ​​the counting and stacking device.

[0035] Specifically, the chain drive mechanism includes a dual-shaft output reducer 3, a chain drum 4, a guide sprocket 5, and a first chain 7. The dual-shaft output reducer 3 is installed at the top center of the "U"-shaped frame 1. The output shaft of the dual-shaft output reducer 3 is rotatably mounted on the housing 2 symmetrically arranged at the top of the frame 1. The output shaft extends into the housing 2 and is fixed to the chain drum 4. The guide sprocket 5 is located inside the housing 2. One end of the first chain 7 is fixed to the chain drum 4, cuts around the chain drum 4, passes through the guide sprocket 5, and then passes out of the housing 2 to connect to the lifting counting and stacking mechanism.

[0036] In this embodiment, when the dual-shaft output reducer 3 rotates forward, it drives the chain drum 4 to rotate forward, thereby pulling the first chain 7 to raise the lifting counting and stacking mechanism. When the dual-shaft output reducer 3 rotates in reverse, the chain drum 4 rotates in reverse, thereby loosening the first chain 7 to lower the lifting counting and stacking mechanism.

[0037] Specifically, the lifting counting and stacking mechanism includes side plates 8, a first baffle 12, a second baffle 13, and a sliding rod 11. The two symmetrically arranged side plates 8 are connected by multiple square rods 9. Each side plate 8 has two sets of equal-height rolling limit components on its inner side. Each set of rolling limit components includes two upper and lower stepped grooved wheels 10. The sliding rod 11 is located between the two stepped grooved wheels 10, and the first stepped groove 1001 of the stepped grooved wheel 10 rolls in contact with the sliding rod 11. The first baffle 12 is fixed to the square rod 9, and the second baffle 13 is fixed to the front end of the sliding rod 11. The area between the first baffle 12 and the second baffle 13 is the carton stacking area. A rotating rod 19 is rotatably installed between the side plates 8. A transmission sprocket 21 is set on the rotating rod 19. A first handwheel 20 is set at the right end of the rotating rod 19. A second chain 22 is connected to the top of the front end of the sliding rod 11. The second chain 22 passes through the second stepped groove 1002 of the upper stepped groove wheel 10 of the first set of rolling limit components and then meshes with the transmission sprocket 21. After passing through the second stepped groove 1002 of the upper stepped groove wheel 10 of the second set of rolling limit components, it is connected to the top of the rear end of the sliding rod 11. The lower end of the first chain 7 is connected to the side plate 8. A photoelectric counter 48 is set on the lower inner side of the side plate 8. A pair of partition support components are symmetrically arranged on the outer sides of the first baffle 12 and the second baffle 13.

[0038] In this embodiment, by rotating the first handwheel 20, the rotating rod 19 is driven to rotate, and the transmission sprocket 21 rotates accordingly. The transmission sprocket 21 drives the second chain 22, causing the sliding rod 11 to move horizontally back and forth between the stepped grooved wheels 10, thereby changing the position of the second baffle 13 and adjusting the distance between the first baffle 12 and the second baffle 13. This makes the counting stacking machine suitable for the neat stacking of corrugated cardboard boxes of different widths.

[0039] Specifically, the partition support assembly provided on the outer side of the second baffle 13 includes a gear 14, a support plate 15, a rack 16, a guide wheel 17, and a first electric cylinder 18. Multiple equidistant gears 14 are rotatably mounted on the second baffle 13 via a mounting shaft. The support plate 15 is located below the gears 14, with one end fixed to the mounting shaft. The horizontally arranged rack 16 meshes with the gears 14. Multiple guide wheels 17 are rotatably mounted on the second baffle 13, with the grooves of the guide wheels 17 rolling in contact with the rack 16. One end of the rack 16 is connected to the piston rod of the first electric cylinder 18 mounted on the second baffle 13. Both the first baffle 12 and the second baffle 13 have slotted holes allowing the support plate 15 to rotate through. A scale is provided on the outer surface of the sliding rod 11, and a notch is provided on the side plate 8 directly below the first handwheel 20, with a pointer 23 positioned at the notch.

[0040] In this embodiment, a photoelectric counter 48 automatically counts the cartons falling from above the carton stacking area. When the quantity reaches the required packaging quantity, the first electric cylinder 18 pushes the rack 16, causing the gear 14 meshing with the rack 16 to rotate. This causes the pallet 15 to rotate and extend through the slot to the top of the carton stacking area. The pallet 15 then catches the next batch of cartons being transported by the first conveyor to the carton stacking area. Simultaneously, the dual-shaft output reducer 3 rotates forward, and the chain drive mechanism drives the lifting counting and stacking mechanism to rise, facilitating the transport of the neatly stacked cartons on the second conveyor out of the carton stacking area. Then, the dual-shaft output reducer 3 reverses, and the lifting counting and stacking mechanism below the chain drive mechanism descends and resets. At this time, the first electric cylinder 18 pulls the rack 16 to reset, causing the gear 14 meshing with the rack 16 to rotate. This causes the pallet 15 to rotate and reset through the slot, facilitating the cartons to fall onto the second conveyor in the carton stacking area for the next batch of counting and stacking.

[0041] Specifically, in order to improve the stability of the lifting and stacking mechanism, at least one set of guide rollers 49 is installed on the outer side of the side plate 8, and the guide rollers 49 roll in contact with the guide rails 6 vertically arranged on the inner side wall of the frame 1.

[0042] Specifically, in order to improve the safety of the lifting and stacking mechanism and avoid accidents caused by the uncontrolled rapid descent of the lifting and stacking mechanism due to unexpected reasons, a protective stop assembly is provided on the outer side of the side plate 8. The protective stop assembly includes a support plate 25, a locking strip 26, a tension spring 27, and a second electric cylinder 28. The support plate 25 is fixed to the outer wall of the side plate 8. The middle part of the locking strip 26 is rotatably mounted on the support plate 25. One end of the tension spring 27 is connected to the upper outer end of the locking strip 26, and the other end is connected to the outer side of the support plate 25. The second electric cylinder 28 is installed on the top of the support plate 25, and the piston rod of the second electric cylinder 28 is directly opposite the upper end of the locking strip 26. A ratchet rack 24 that matches and abuts against the lower end of the locking strip 26 is provided on the front side wall of the frame 1.

[0043] In this embodiment, when the lifting counting and stacking mechanism is working in its original position, the tension spring 27 pulls the upper end of the normal locking bar 26, causing the lower end of the locking bar 26 to abut against the ratchet 24. When the lifting counting and stacking mechanism needs to be raised or lowered, the second electric cylinder 28 pushes the upper end of the locking bar 26, causing the lower end of the locking bar 26 to slide out of the ratchet 24, so that the lifting counting and stacking mechanism can rise or fall.

[0044] Specifically, a stacking auxiliary mechanism is slidably mounted on the two sliding rods 11. The stacking auxiliary mechanism includes a support rod 29, a sliding member 30, a second handwheel 31, a sliding sleeve 32, and a limiting baffle 34. The sliding member 30 includes a side slide plate 3001, a connecting column 3002, a first rotating shaft 3003, and a single groove wheel 3004. The two symmetrically arranged side slide plates 3001 are connected by multiple connecting columns 3002. The lower part of the side slide plate 3001 is slidably mounted on the sliding rod 11. The two ends of the first rotating shaft 3003 are connected to the side slide plate 3001. The moving connection is as follows: a single grooved wheel 3004 is located between two side slide plates 3001. The single grooved wheel 3004 is fixed on the first rotating shaft 3003. The inner side slide plate 3001 is fixedly connected to the square support rod 29. One end of the first rotating shaft 3003 passes through the outer side slide plate 3001 and is connected to the second handwheel 31. A scale is provided on the front side of the support rod 29. Two sliding sleeves 32 are slidably fitted on the support rod 29. An adjusting screw 33 is installed on the top of the sliding sleeve 32. A limiting baffle 34 is connected to the bottom of the sliding sleeve 32. The two limiting baffles 34 are symmetrically arranged.

[0045] In this embodiment, by rotating the second handwheel 31, the single groove wheel 3004 slides along the sliding rod 11 under the guiding and limiting action of the side slide plate 3001, thereby adjusting the distance between the limiting baffle 34 and the first baffle 12. By rotating and loosening the adjusting screw 33, the sliding sleeve 32 can slide on the support rod 29, thereby adjusting the distance between the two limiting baffles 34, making this counting stacking machine suitable for neat stacking of corrugated cartons of different lengths and sizes.

[0046] Specifically, the conveying mechanism includes a drive wheel 37 and a conveying frame 39. The conveying frame 39 includes a rectangular frame 3901, with multiple equidistant support square tubes 3902 inside the frame 3901. Hanging members 3904 are provided at both ends of the frame 3901. The multiple drive wheels 37 are mounted on a third rotating shaft 3903, which is rotatably mounted at the rear end of the conveying frame 39. One end of the third rotating shaft 3903 is connected to the output shaft of a drive motor 40 mounted on the conveying frame 39. The sliding support mechanism includes a bracket 42, a slider 43, and slide rails 44. Two parallel dovetail-shaped slide rails 44 are fixed... The slider 43, which is fixed on the ground and matches the slide rail 44, is slidably mounted on the slide rail 44. A bracket 42 is set on the top of the slider 43. The brackets 42 are connected by a connecting rod 41. The hanger 3904 at the rear end of the frame 3901 is rotatably hung on the connecting rod 41. A second rotating shaft 36 is also rotatably mounted between the two side plates 8. Multiple driven wheels 35 are mounted on the second rotating shaft 36. The driven wheels 35 are connected to the driving wheel 37 by a conveyor belt 38. The top surface of the supporting square tube 3902 is in contact with the conveyor belt 38. The hanger 3904 at the front end of the frame 3901 is hung on the second rotating shaft 36.

[0047] In this embodiment, the hanging parts 3904 at both ends of the frame 3901 of the conveyor frame 39 are rotatably installed on the sliding support mechanism and the lifting counting and stacking mechanism, and continuously convey the carton during the lifting and stacking process in conjunction with the lifting counting and stacking mechanism.

[0048] Specifically, a pressing mechanism is also installed between the left and right side plates 8. The pressing mechanism includes a pressure roller 45, a telescopic rod 46, and a mounting rod 47. Multiple pressure rollers 45 are provided. The pressure rollers 45 are located above the driven wheel 35. The pressure rollers 45 are in rolling contact with the conveyor belt 38 on the outer side of the top of the driven wheel 35. The lower end of the telescopic rod 46 is rotatably mounted on the pressure roller 45, and the upper end of the telescopic rod 46 is rotatably mounted on the mounting rod 47. The two ends of the mounting rod 47 are fixed to the left and right side plates 8.

[0049] In this embodiment, the corrugated carton is fed into the carton stacking area between the pressure roller 45 and the conveyor belt 38 on the outer side of the top of the driven roller 35, which improves the stability of the carton falling into the carton stacking area.

[0050] Specifically, the rear side wall of the frame 1 is provided with a lower limit switch 50 and an upper limit switch 51. The outer side of the side plate 8 is provided with a collision block 52 that matches the lower limit switch 50 and the upper limit switch 51. The collision block 52 is located between the lower limit switch 50 and the upper limit switch 51. The lower limit switch 50 and the upper limit switch 51 are respectively electrically connected to an independently provided PLC control cabinet 54. The PLC control cabinet 54 is also electrically connected to the dual-axis output reducer 3, the first electric cylinder 18, the second electric cylinder 28, the drive motor 40, and the photoelectric counter 48.

[0051] In this embodiment, a travel limit mechanism is formed by the lower limit switch 50, the upper limit switch 51, and the collision block 52 to prevent the lifting counting and stacking mechanism from rising or falling beyond the safe position, thereby improving the safety of equipment operation. In practical applications, the motor that drives the conveyor rollers on the roller conveyor 53 is also electrically connected to the PLC control cabinet 54. The operation of the counting and stacking machine is controlled by the PLC control cabinet 54, improving the automation level of the corrugated carton counting and stacking production process.
