Description

Technical Field

[0001] The invention belongs to the technical field of packaging, and in particular relates to a proportioning packaging line and a packaging method thereof. Background Art

[0002] In the process of box packing, according to customer needs or combined sales, two different boxes need to be placed in a large box in a ratio. For example, a large box is filled with medium boxes according to the formula of A:B=4:6. Then a dedicated person is required to identify the model and quantity of the boxes, which requires a lot of manual effort. On the one hand, manual counting will cause fatigue. On the other hand, abnormal materials will appear in the weighing, labeling, and cigarette film processes before packing, and the abnormal materials need to be removed in the production line, which disrupts the original rhythm. Therefore, it is urgent to design an intelligent ratio packing line. Summary of the invention

[0003] The purpose of the present invention is to provide a proportioning packing line and a packing method thereof in order to solve the above-mentioned technical problems, so as to improve the packing quality and efficiency.

[0004] In view of this, the present invention provides a proportioning and packing assembly line, comprising a main conveyor belt, and the following are arranged in sequence along the transmission direction of the main conveyor belt:

[0005] Incoming material sorting component, the incoming material sorting component is used to initially arrange the boxes transmitted to the assembly line so that the long side of the boxes is parallel to the transmission direction of the assembly line;

[0006] A weighing machine, the weighing machine is used to weigh the box;

[0007] An empty package rejection component, which is used to reject boxes with unqualified weights as measured by a weighing machine;

[0008] An adjustment component, the adjustment component is used to adjust the angle of the box;

[0009] A labeling component, wherein the labeling component is used to label the box;

[0010] A cigarette film assembly, the cigarette film assembly is used for cigarette filming the box;

[0011] A material dividing and circulation component, which is used to distinguish boxes and circulate different boxes in different zones;

[0012] A packing assembly is used to pack the matched boxes together.

[0013] In this technical solution, this production line can detect and remove materials with different weights and labels in a timely manner to prevent them from flowing out, and the material separation and circulation components can separate and circulate the boxes, reducing the labor consumption and error rate of proportioning and improving the quality and efficiency of packing.

[0014] Furthermore, the incoming material sorting assembly includes at least two inclined guide plates, and the two guide plates are inclined in opposite directions and staggered with each other.

[0015] Furthermore, the empty packet removal component includes:

[0016] A first material shifting assembly, the first material shifting assembly comprises a material shifting frame, a rotatable transmission chain is arranged on the material shifting frame, the transmission chain is connected to a material shifting plate and can move the material shifting plate to complete material shifting, a pulley is connected to the material shifting plate, and a guide groove for accommodating the pulley is arranged on the material shifting frame;

[0017] The empty package cache line is arranged on the side of the first material selection component and the main conveyor belt and is perpendicular to the main conveyor belt. The empty package cache line is used to receive boxes with unqualified weight selected from the first material selection component.

[0018] In this technical solution, the transmission chain moves the material stripping plate to complete the material stripping, and the pulley can make the material stripping plate slide more smoothly. At the same time, the pulley slides in the guide groove to support the material stripping plate to make the sliding of the material stripping plate more stable. When the material stripping plate is under the transmission chain, the transmission chain will not sag.

[0019] Furthermore, the adjustment component includes:

[0020] A visual recognition component, wherein the visual recognition component includes a first camera, which is arranged directly above the main conveyor belt. A mark is arranged on the upper surface of the box. The visual recognition component is used to take a picture of the box to determine the front and rear orientation of the box and the deviation angle between the length direction of the box and the conveying direction of the main conveyor belt;

[0021] A second material shifting assembly, the second material shifting assembly is used to push the boxes on the main conveyor belt that are identified by the visual recognition assembly and are determined to need adjustment to the adjustment conveyor belt;

[0022] A rotary assembly, which is arranged on one side of the adjustment conveyor belt and is used to receive boxes that need to be adjusted. A material guide plate is arranged on the other side of the adjustment conveyor belt. The rotary assembly is arranged between the adjustment conveyor belt and the main transmission belt. The rotary assembly includes a large rotating disk that can rotate in a circumferential direction and four small rotating disks that are rotatably arranged on the large rotating disk.

[0023] A two-way pushing assembly is arranged on the rotary assembly. The two-way pushing assembly can push materials in both directions. The two-way pushing assembly is used to push the unmarked boxes photographed by the first camera on the adjustment conveyor belt toward the special material guide plate. The two-way pushing assembly is also used to push the adjusted boxes on the small turntable on the rotary assembly close to the main conveyor belt side back to the main conveyor belt.

[0024] In the present technical solution, after the visual recognition component takes a bird's-eye view photo of the box on the main conveyor belt, it makes a judgment and analysis. If there is a mark on the box in the photo and the mark angle is correct, the position of the marked box is completely correct, and the box continues to be transported directly along the main conveyor belt. In other cases, the second material shifting component shifts the box to the adjustment conveyor belt. If there is no mark on the box in the photo, it means that the upper surface of the box is not facing up, and the two-way pushing component pushes the box to the foreign material guide plate. In other cases, the two-way pushing component pushes the box to the small turntable on the large turntable close to the adjustment conveyor belt side. If the mark on the box in the photo is upside down, the small turntable does not rotate. , only the large turntable rotates, and when the box is driven by the large turntable to rotate close to the main conveyor belt side, the box mark is facing the correct direction, which means that the box position and posture are adjusted to the correct state. If the mark on the box in the photo is only slightly deviated, the small turntable rotates a certain angle to make the mark on the box inverted. Then the large turntable rotates, and when the box is driven by the large turntable to rotate close to the main conveyor belt side, the box mark is facing the correct direction, which means that the box position and posture are adjusted to the correct state. Finally, the two-way pushing component pushes the adjusted box on the small turntable close to the main conveyor belt back to the main conveyor belt. The first material shifting component of the empty package rejection component is roughly the same as the second material shifting component and the two-way pushing component of the adjustment component, which will not be repeated here. The adjustment component can make the box position and posture correct, prepare for the next step of labeling, and improve the accuracy of labeling.

[0025] Furthermore, the labeling assembly includes:

[0026] A labeling machine, which is used to label boxes;

[0027] The labeling abnormality screening component is used to screen out boxes with labeling abnormalities.

[0028] Furthermore, the labeling abnormality screening component includes:

[0029] A second camera, which is arranged just above the main conveyor belt behind the labeling machine, and is used to take pictures of the labeled boxes to identify boxes with abnormal labeling;

[0030] A labeling abnormality cache line, the labeling abnormality cache line is arranged at the side of the main conveyor belt;

[0031] The third material shifting component is arranged behind the second camera, and can shift the boxes with abnormal labeling to the abnormal labeling cache line.

[0032] In this technical solution, after the labeling machine labels the box, the box flows under the second camera, and the second camera takes a bird's-eye view of the box. If it is found after comparison that the labeling position is incorrect, the third material shifting component will shift the box to the labeling abnormality cache line.

[0033] Furthermore, the material distribution and circulation component comprises:

[0034] The third camera is used by the labeling machine to take photos of the boxes for identification;

[0035] The shunt line includes a first shunt line, a second shunt line, a third shunt line, a fourth shunt line, and a fifth shunt line which are arranged in parallel and have the same transmission direction, the first shunt line is used to cache boxes of indistinguishable types, the second shunt line, the third shunt line, the fourth shunt line, and the fifth shunt line are used to circulate boxes, and a sixth shunt line is arranged on the side of the fifth shunt line away from the fourth shunt line, the sixth shunt line has a transmission direction opposite to that of the fifth shunt line, and the sixth shunt line is used to return excess boxes of the fifth shunt line;

[0036] An identification cache line is perpendicular to the shunt line and located at the entrance side of the shunt line. Positions on the identification cache line corresponding to the first shunt line, the second shunt line, the third shunt line, the fourth shunt line and the fifth shunt line are all provided with a fourth material selection component.

[0037] Furthermore, a fifth material shifting assembly is provided between the fifth diversion line and the sixth diversion line, and the fifth material shifting assembly is used to shift the redundant boxes of the fifth diversion line to the sixth diversion line.

[0038] In the present technical solution, after the boxes are smoked with film, they need to be packed in proportion. The boxes are transferred to the third camera. After the third camera takes pictures of the boxes to distinguish them, the boxes flow into the corresponding position of the identification cache line. Then the fourth material shifting component of the identification cache line shifts the boxes to a corresponding diversion line for transmission. If the boxes cannot be distinguished, they are shifted to the first diversion line, and the boxes with the largest number are arranged to the fifth diversion line. If it is found that there are too many boxes on the fifth diversion line, they can be transferred to the sixth diversion line under the shifting of the fifth material shifting component for reflux.

[0039] Furthermore, the packaging component includes a stacking area for stacking, binding and packing of multiple boxes.

[0040] Furthermore, the packing method of the proportioning packing line includes the following steps:

[0041] Step S1: Arrange incoming materials and arrange the boxes transmitted to the assembly line so that the long side of the boxes is parallel to the transmission direction of the assembly line;

[0042] Step S2: weighing, using a weighing machine to weigh the box;

[0043] Step S3: Empty package rejection: the empty package rejection component rejects the boxes with unqualified weights weighed by the weighing machine to the empty package buffer line;

[0044] Step S4: Adjust the angle of the box. After the visual recognition component takes a bird's-eye view photo of the box on the main conveyor belt, it makes a judgment and analysis. If there is a mark on the box in the photo and the mark angle is correct, the position of the marked box is completely correct, and the box continues to be transported directly along the main conveyor belt. In other cases, the second material shifting component shifts the box to the adjustment conveyor belt. If there is no mark on the box in the photo, it means that the upper surface of the box is not facing up, and the two-way pushing component pushes the box to the foreign material guide plate. If there is a mark on the box in the photo but the angle is incorrect, the two-way pushing component pushes the box to the small turntable on the large turntable close to the adjustment conveyor belt side. If the mark on the box in the photo is reversed, If the box is reversed, the small turntable does not rotate, but only the large turntable rotates. When the box is driven by the large turntable to rotate to the side close to the main conveyor belt, the box mark is facing the correct direction, which means that the box position and posture are adjusted to the correct state. If the mark on the box in the photo is only slightly deviated, the small turntable rotates a certain angle to make the mark on the box inverted. Then the large turntable rotates. When the box is driven by the large turntable to rotate to the side close to the main conveyor belt, the box mark is facing the correct direction, which means that the box position and posture are adjusted to the correct state. Finally, the two-way pushing assembly pushes the adjusted box on the small turntable close to the main conveyor belt back to the main conveyor belt.

[0045] Step S5: labeling. After the labeling machine labels the box, the box flows to the bottom of the second camera. The second camera takes a bird's-eye view of the box. If the labeling position is found to be incorrect after comparison, the third material shifting component shifts the box to the abnormal labeling cache line.

[0046] Step S6: the cigarette film component applies cigarette film to the box;

[0047] Step S7: material distribution and circulation. After the boxes are filmed, they need to be packed in proportion. The boxes are transferred to the third camera. After the third camera takes a photo of the boxes and distinguishes them, the boxes flow into the corresponding position of the identification cache line. Then the fourth material shifting component of the identification cache line shifts the boxes to a corresponding diversion line for transmission. If the boxes cannot be distinguished, they are shifted to the first diversion line. The boxes of the largest number are arranged to the fifth diversion line. If it is found that there are too many boxes on the fifth diversion line, they can be transferred to the sixth diversion line under the shifting of the fifth material shifting component for reflux.

[0048] Step S8: Packing: stacking, binding and packing multiple boxes in a proportioned manner in the box stacking area.

[0049] The beneficial effects of the present invention are:

[0050] 1. This production line can detect and remove materials with different weights and labels in time to prevent them from flowing out. The material separation and circulation components can separate and circulate boxes, reduce the labor consumption and error rate of proportioning, and improve the quality and efficiency of packing.

[0051] 2. The conveyor chain moves the material-discharging plate to complete the material-discharging. The pulley can make the material-discharging plate slide more smoothly. At the same time, the pulley slides in the guide groove to support the material-discharging plate to make the sliding of the material-discharging plate more stable. When the material-discharging plate is under the conveyor chain, the conveyor chain will not sag.

[0052] 3. By adjusting the components, the box position and posture can be correct, preparing for the next step of labeling and improving the accuracy of labeling. BRIEF DESCRIPTION OF THE DRAWINGS

The material separation and circulation component 8 can separate and circulate boxes, thus reducing the labor consumption and error rate of proportioning and improving the quality and efficiency of box packing.

[0080] Embodiment 2

[0081] like Figure 2 As shown, the incoming material sorting assembly 2 includes at least two inclined guide plates 10, and the two guide plates 10 are inclined in opposite directions and staggered with each other.

[0082] Embodiment 3

[0083] like Figure 3-4 As shown, the empty package removal component 4 includes:

[0084] A first material shifting assembly 11, comprising a material shifting frame 12, on which a rotatable transmission chain 13 is disposed, the transmission chain 13 is connected to a material shifting plate 17 and can move the material shifting plate 17 to complete material shifting, a pulley 14 is connected to the material shifting plate 17, and a guide groove 15 for accommodating the pulley 14 is disposed on the material shifting frame 12;

[0085] The empty package buffer line 16 is arranged on the side of the first material selection component 11 and the main conveyor belt 1 and is perpendicular to the main conveyor belt 1. The empty package buffer line 16 is used to receive boxes with unqualified weight selected from the first material selection component 11.

[0086] The transmission chain 13 moves with the material stripping plate 17 to complete the material stripping. The pulley 14 can make the material stripping plate 17 slide more smoothly. At the same time, the pulley 14 slides in the guide groove 15 to support the material stripping plate 17 to make the sliding of the material stripping plate 17 more stable. When the material stripping plate 17 is below the transmission chain 13, the transmission chain 13 will not sag.

[0087] Embodiment 4

[0088] like Figure 5-6 As shown, the adjustment component 5 includes:

[0089] A visual recognition component, the visual recognition component includes a first camera 18, the first camera 18 is arranged directly above the main conveyor belt 1, and a mark 19 is arranged on the upper surface of the box. The visual recognition component is used to take a picture of the box to determine the front and rear orientation of the box and the deviation angle between the length direction of the box and the conveying direction of the main conveyor belt 1;

[0090] A second material shifting assembly 20, which is used to push the boxes on the main conveyor belt 1 that are identified by the visual recognition assembly and are determined to need adjustment to the adjustment conveyor belt 21;

[0091] A rotary assembly, which is arranged on one side of the adjustment conveyor belt 21 and is used to receive boxes that need to be adjusted.

[0092] The bidirectional pushing component 25 is arranged on the rotary component. The bidirectional pushing component 25 can push materials in both directions. The bidirectional pushing component 25 is used to push the boxes without marks 19 photographed by the first camera 18 on the adjustment conveyor belt 21 toward the special material guide plate 22. The bidirectional pushing component 25 is also used to push the adjusted boxes on the small turntable 24 on the rotary component close to the side of the main conveyor belt 1 back to the main conveyor belt 1.

[0093] After the visual recognition component takes a bird's-eye view photo of the box on the main conveyor belt 1, it judges and analyzes that if there is a mark 19 on the box in the photo and the angle of the mark 19 is correct, the position of the box with the mark 19 is completely correct, and the box continues to be transported directly along the main conveyor belt 1. In other cases, the second material shifting component 20 shifts the box to the adjustment conveyor belt 21. If there is no mark 19 on the box in the photo, it means that the upper surface of the box is not facing up, and the two-way pushing component 25 pushes the box to the different material guide plate 22. In other cases, the two-way pushing component 25 pushes the box to the small turntable 24 on the large turntable 23 close to the side of the adjustment conveyor belt 21. If the mark 19 on the box in the photo is upside down, the small turntable 24 does not rotate by itself, but only The large turntable 23 rotates, and when the box is driven by the large turntable 23 to rotate to the side close to the main conveyor belt 1, the box mark 19 just faces the correct direction, which means that the box position and posture are adjusted to the correct state. If the mark 19 on the box in the photo is only a small angle deviation, the small turntable 24 rotates a certain angle to make the mark 19 on the box form a reversed state, and then the large turntable 23 rotates, and when the box is driven by the large turntable 23 to rotate to the side close to the main conveyor belt 1, the box mark 19 just faces the correct direction, which means that the box position and posture are adjusted to the correct state. Finally, the two-way push component 25 pushes the adjusted box on the small turntable 24 close to the main conveyor belt 1 back to the main conveyor belt 1. The first material shifting component 11 of the empty package rejection component 4 and the second material shifting component 20 and the two-way push component 25 of the adjustment component 5 are roughly the same in structure, which will not be repeated here.

The first shunt line 31 is used to cache boxes of indistinguishable types. The second shunt line 32, the third shunt line, the fourth shunt line, and the fifth shunt line 34 are used to circulate boxes. A sixth shunt line 35 is arranged on the side of the fifth shunt line 34 away from the fourth shunt line. The sixth shunt line 35 has a transmission direction opposite to that of the fifth shunt line 34. The sixth shunt line 35 is used to return excess boxes from the fifth shunt line 34.

[0107] The identification cache line 40 is perpendicular to the shunt line and located at the entrance side of the shunt line. The positions on the identification cache line 40 corresponding to the first shunt line 31, the second shunt line 32, the third shunt line, the fourth shunt line and the fifth shunt line 34 are all provided with a fourth material selection component 41.

[0108] Furthermore, a fifth material shifting assembly 42 is provided between the fifth diversion line 34 and the sixth diversion line 35 , and the fifth material shifting assembly 42 is used to shift excess boxes of the fifth diversion line 34 to the sixth diversion line 35 .

[0109] After the boxes are smoked, they need to be packed in proportion. The boxes flow to the third camera 30. After the third camera 30 takes a photo of the boxes to distinguish them, the boxes flow into the corresponding position of the identification cache line 40. Then the fourth material shifting component 41 of the identification cache line 40 shifts the boxes to a corresponding diversion line for transmission. If the boxes cannot be distinguished, they are shifted to the first diversion line 31, and the largest number of boxes are arranged to the fifth diversion line 34. If it is found that there are too many boxes on the fifth diversion line 34, they can be transferred to the sixth diversion line 35 under the shifting of the fifth material shifting component 42 for reflux.

[0110] Embodiment 7

[0111] like Fig. 9 As shown, the packaging component 9 includes a stacking area 43, and the stacking area 43 is used for stacking, binding and packing of multiple boxes.

[0112] The packing method of the proportion packing line includes the following steps:

[0113] Step S1: Arrange incoming materials and arrange the boxes transmitted to the assembly line so that the long side of the boxes is parallel to the transmission direction of the assembly line;

If there is a mark 19 on the box in the photo and the angle of the mark 19 is correct, the position of the box with the mark 19 is completely correct, and the box continues to be transported directly along the main conveyor belt 1. In other cases, the second material shifting component 20 shifts the box to the adjustment conveyor belt 21. If there is no mark 19 on the box in the photo, it means that the upper surface of the box is not facing up, and the two-way pushing component 25 pushes the box to the different material guide plate 22. If there is a mark 19 on the box in the photo but the angle is incorrect, the two-way pushing component 25 pushes the box to the small turntable 24 on the large turntable 23 close to the adjustment conveyor belt 21 side. If the mark 19 on the box in the photo is positive and negative, the two-way pushing component 25 pushes the box to the small turntable 24 on the large turntable 23 close to the adjustment conveyor belt 21 side. If the box is reversed, the small turntable 24 does not rotate, and only the large turntable 23 rotates. When the box is driven by the large turntable 23 to rotate to the side close to the main conveyor belt 1, the box mark 19 just faces the correct direction, indicating that the box position and posture are adjusted to the correct state. If the mark 19 on the box in the photo is only slightly deviated, the small turntable 24 rotates a certain angle to make the mark 19 on the box form a reversed state, and then the large turntable 23 rotates. When the box is driven by the large turntable 23 to rotate to the side close to the main conveyor belt 1, the box mark 19 just faces the correct direction, indicating that the box position and posture are adjusted to the correct state. Finally, the two-way pushing assembly 25 pushes the adjusted box on the small turntable 24 close to the main conveyor belt 1 back to the main conveyor belt 1;

[0117] Step S5: labeling. After the labeling machine 26 labels the box, the box flows to the bottom of the second camera 27. The second camera 27 takes a top view of the box. If it is found that the labeling position is incorrect after comparison, the third material shifting component 29 shifts the box to the labeling abnormality cache line 28;

[0118] Step S6: the cigarette film component 7 applies cigarette film to the box;

[0119] Step S7: material distribution and circulation. After the boxes are filmed, they need to be packed in proportion. The boxes are transferred to the third camera 30. After the third camera 30 takes photos of the boxes and distinguishes them, the boxes flow into the corresponding position of the identification cache line 40. Then the fourth material shifting component 41 of the identification cache line 40 shifts the boxes to a corresponding diversion line for transmission. If the boxes cannot be distinguished, they are shifted to the first diversion line 31. The boxes of the largest number are arranged to the fifth diversion line 34. If it is found that there are too many boxes on the fifth diversion line 34, they can be transferred to the sixth diversion line 35 under the shifting of the fifth material shifting component 42 for reflux.

[0120] Step S8: Packing: multiple boxes are stacked, bound and packed in a proportioned manner in the box stacking area 43.
