Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent production and conveying equipment for agricultural product packaging boxes, and particularly relates to a packaging box anti-deviation double-side synchronous deviation rectification conveying equipment and a conveying method. BACKGROUND

[0002] The packaging box anti-deviation double-side synchronous deviation rectification conveying equipment is an automatic equipment for solving the deviation problem of packaging boxes in the conveying process, and the core function is to ensure that the packaging boxes maintain the correct position on the conveying line and avoid deviation from affecting the subsequent process. When deviation is detected, the deviation rectification mechanisms (such as baffle, air cylinder, and servo motor driven push plate) on both sides of the equipment act synchronously to correct the packaging boxes back to the center position of the conveying line, avoiding secondary skewing or collision caused by single-side deviation rectification.

[0003] Due to the low structural rigidity and light weight of the empty semi-finished packaging boxes (especially corrugated paper packaging boxes for agricultural product packaging), the moving speed of some misaligned and inclined packaging boxes is slowed down after contacting the two-side deviation rectification plates in the traditional packaging box anti-deviation double-side synchronous deviation rectification conveying equipment, which leads to a smaller and smaller space between the packaging boxes behind and the packaging boxes, and thus the packaging boxes are prone to accumulate at the deviation rectification plate, forcing the whole line to stop and clear the obstacles. The accumulated empty boxes are deformed under extrusion (corrugated paper crushing rate > 5%), increasing the loss of raw materials.

[0055] Second embodiment

[0056] Based on the packaging box anti-deviation double-side synchronous deviation-correcting conveying equipment provided in the first embodiment of the application, the second embodiment of the application provides another packaging box anti-deviation double-side synchronous deviation-correcting conveying equipment. The second embodiment is only a preferred mode of the first embodiment. The implementation of the second embodiment does not affect the separate implementation of the first embodiment.

[0057] The second embodiment of the application will be further described below in combination with the drawings and the embodiments.

[0058] Please refer to Figures 7-12The packaging box anti-deviation double-side synchronous deviation correction conveying equipment further comprises a sub-channel 25 fixedly installed on one side of the base 1, and fixed racks 28 are fixedly installed on both sides of the sub-channel 25. A same third frame is fixedly installed on the top of the base 1 and the top of the fixed rack 28, and a box pushing mechanism is arranged in the third frame. The box pushing mechanism is used for pushing the packaging boxes with a stacking trend into the sub-channel 25, and pushing the packaging boxes to the second conveying belt 5 again after the other packaging boxes are conveyed by the second conveying belt 5. The box pushing mechanism is arranged above the second conveying belt 5.

[0059] The box pushing mechanism comprises a screw rod 22, a moving plate 21, a cylinder 20, a third motor 19, a poking plate 30 and a visual detection device 29. The moving plate 21 is slidingly installed in the third frame, the screw rod 22 is rotatably installed on the top of the third frame, the third motor 19 is fixedly installed on the top of the third frame, one end of the screw rod 22 is fixedly connected with the output shaft of the third motor 19, the moving plate 21 is threadedly connected with the screw rod 22, the poking plate 30 is slidingly installed in the moving plate 21, the cylinder 20 is fixedly installed on one side of the moving plate 21, and the extending end of the cylinder 20 is fixedly connected with the poking plate 30. The visual detection device 29 is fixedly installed on the bottom of the third frame. When the visual detection device 29 detects that the packaging boxes are stacked, the third motor 19 is started, and part of the redundant packaging boxes are immediately moved to the sub-channel 25 for temporary storage through the poking plate 30, so as to avoid the whole production line from stopping due to blockage.

[0060] Two fixed racks 28 are arranged with sorting conveying mechanisms. The sorting conveying mechanism comprises a linkage assembly and two groups of sorting assemblies. The linkage assembly is used for driving the two groups of sorting assemblies to operate synchronously. The sorting assembly is used for temporarily storing the packaging boxes and intermittently conveying the packaging boxes to the second conveying belt 5.

[0061] Any one sorting assembly comprises two third rotating rods 32, two second fixed cylinders 37, a third conveying belt 27 and a plurality of baffles 26. The two third rotating rods 32 are rotatably installed in the fixed rack 28, and the top end and the bottom end of the two third rotating rods 32 extend out of the fixed rack 28. The two second fixed cylinders 37 are fixedly installed on the outer walls of the two third rotating rods 32. The plurality of baffles 26 are fixedly installed on the outer wall of the third conveying belt 27. A fourth motor 31 is fixedly installed on one side of the fixed rack 28. The top end of one of the third rotating rods 32 is in transmission connection with the fourth motor 31. A dial 24 is fixedly installed on the top of one of the gear wheels 23. The gear wheel 23 is matched with the dial 24. Through the cooperation of the dial 24 and the gear wheel 23, the temporarily stored packaging boxes can be intermittently conveyed to the second conveying belt 5, so that there is a larger space between the packaging boxes, preventing the packaging boxes from being stacked between the deviation correction baffles 3 when the packaging boxes are corrected again.

[0062] The linkage assembly comprises a second belt 33, a first gear 34, a rotating shaft 35, and a second gear 36. The rotating shaft 35 is rotatably installed at the bottom of the fixed frame 28. The first gear 34 is fixedly installed on the outer wall of the rotating shaft 35. The second gear 36 is fixedly installed on the outer wall of the corresponding third rotating rod 32 and is engaged with the first gear 34. The outer wall of the third rotating rod 32 and the outer wall of the corresponding rotating shaft 35 are both fixedly installed with belt pulleys. The second belt 33 is sleeved on the two belt pulleys.

[0063] In the embodiment,

[0064] When the packaging boxes are deviated, the misaligned packaging boxes will slow down after contacting the deviation blocking plate 3, and the gap between the packaging boxes will become smaller, which causes the packaging boxes to be easily stacked at the limiting plate. When the visual inspection equipment 29 observes that there is a risk of packaging box stacking on the second conveying belt 5, the third motor 19 is started to drive the screw rod 22 to rotate, and the screw rod 22 drives the moving plate 21 to reciprocate. The partial packaging boxes are pushed into the sub-channel 25 through the push plate 30. After the pushing is completed, the air cylinder 20 is started, and the telescopic end of the air cylinder 20 drives the push plate 30 to rise. At this time, the fourth motor 31 is started, and the fourth motor 31 drives the third conveying belt 27 on both sides of the sub-channel 25 to intermittently rotate through the ratchet wheel 23 and the dial 24 and through the cooperation of the second belt 33, the first gear 34, and the second gear 36. The partial packaging boxes are concentrated between the multiple blocking plates 26 and are separated from each other. The fourth motor 31 is turned off. When the packaging boxes on the second conveying belt 5 are conveyed, the fourth motor 31 is started again to reverse the fourth motor 31. The packaging boxes are conveyed to the position close to the second conveying belt 5 through the blocking plate 26. The air cylinder 20 and the third motor 19 are started respectively. The telescopic end of the air cylinder 20 drives the push plate 30 to descend, and the third motor 19 drives the screw rod 22 to rotate, so that the push plate 30 pushes the packaging boxes onto the second conveying belt 5 again. Since the third conveying belt 27 is intermittently rotated, there is a certain space between the packaging boxes when they are conveyed to the second conveying belt 5, which avoids the risk of stacking again.
