Detailed Implementation

[0013] Figures 1 to 6The present invention provides a schematic diagram of an embodiment of an automatic labeling device for dovetail labels on irregularly shaped boxes. The device includes a conveyor belt 1, with a box-holding belt 2 connected to the input end of the conveyor belt 1. Along the conveying direction of the conveyor belt 1, a label feeder 3, a box-separating structure 4, a label-holding belt 5, a label-supporting and label-applying structure 6, a label-tail-supporting structure 7, and a detection and rejection structure 8 are arranged in sequence. The label-dispensing end of the label feeder 3 is provided with a label-peeling and label-applying structure 9, which is located directly above the label-holding belt 5.

[0014] The label peeling and labeling structure 9 includes two mutually symmetrical mounting plates 10. A guide roller 11 and a vertical label plate 12 are connected between the two mounting plates 10, and the guide roller 11 is located above the vertical label plate 12. Each mounting plate 10 is provided with a support rod 13, and each support rod 13 is hinged with a support arm 14. A rotating shaft 15 is connected between the two support arms 14, and a rotatable weight block 16 is provided on the rotating shaft 15.

[0015] The box-separating structure 4 includes a front box-separating cylinder 17 and a rear box-separating cylinder 18. There are two front box-separating cylinders 17 and two rear box-separating cylinders 18. The two front box-separating cylinders 17 are symmetrically distributed on both sides of the conveyor belt 1, and the two rear box-separating cylinders 18 are symmetrically distributed on both sides of the conveyor belt 1. The drive end of each front box-separating cylinder 17 is connected to a front box-separating rod 19, and the drive end of each rear box-separating cylinder 18 is connected to a rear box-separating rod 20.

[0016] There are two labeling structures 6, which are symmetrically distributed on both sides of the conveyor belt 1. Each labeling structure 6 includes a connecting rod 21, which is vertically arranged. An adjusting block 22 is set on the connecting rod 21, and a label brush 23 is set on the adjusting block 22. The label brush 23 is inclined towards the conveyor belt 1.

[0017] By adjusting the height of the adjusting block 22 on the connecting rod 21, the label brush 23 can be adjusted to match the labeling height of the irregularly shaped box 29.

[0018] The marker tail structure 7 includes a marker cylinder 24, the drive end of which is connected to a marker block 25, which is inclined toward the conveyor belt 1.

[0019] The detection and rejection structure 8 includes a rejection cylinder 26 and a recycling box 27. The rejection cylinder 26 and the recycling box 27 are respectively set on both sides of the conveyor belt 1. The drive end of the rejection cylinder 26 is connected to the rejection head 28, and the rejection head 28 is directly facing the recycling box 27.

[0020] The detection rejection structure 8 also includes a labeling detector, which can be a camera.

[0021] The irregularly shaped box 29 of this invention is a hexagonal prism. The irregularly shaped box 29 lies horizontally and is conveyed to the conveyor belt 1 via the box-in clamping belt 2. When the irregularly shaped box 29 passes the box-separating structure 4, two front box-separating cylinders 17 drive the front box-separating rod 19 to extend, causing the front box-separating rod 19 to block the front end of the preceding irregularly shaped box 29. Two rear box-separating cylinders 18 drive the rear box-separating rod 20 to extend, causing the rear box-separating rod 20 to be positioned between the rear end of the preceding irregularly shaped box 29 and the front end of the following irregularly shaped box 29, i.e., the rear box-separating rod 20 is positioned between the two irregularly shaped boxes 29. Two front separating cylinders 17 drive the front separating rod 19 to retract, causing the previous irregularly shaped box 29 to move forward with the conveyor belt 1, thereby aligning the irregularly shaped box 29 and widening the distance between the two irregularly shaped boxes 29. The label feeder 3 conveys the dovetail label 30 to the label peeling and labeling structure 9. The dovetail label 30 is conveyed to the vertical label plate 12 via the guide roller 11. When the dovetail label 30 reaches the bottom of the vertical label plate 12, the dovetail label 30 is peeled off from the backing paper. At this time, the weight block 16 is positioned in front of the dovetail label 30 to support it. When the irregularly shaped box... 29 moves along conveyor belt 1 to labeling clamping belt 5. Under the action of labeling clamping belt 5 and conveyor belt 1, the irregularly shaped box 29 moves forward, causing the dovetail label 30 to be affixed to the front end of the irregularly shaped box 29. At the same time, the irregularly shaped box 29 lifts the weight block 16, causing the weight block 16 to rotate upward. After the irregularly shaped box 29 continues to move forward and leaves the weight block 16, the weight block 16 returns to a vertical state under its own weight. Then, the irregularly shaped box 29 reaches the labeling support structure 6. When it passes the label support brush 23, the label support brush 23 removes the dovetail label 30. The two ends are attached to the side walls of the irregularly shaped box 29. The irregularly shaped box 29 continues forward to the label support structure 7. The label support cylinder 24 drives the label support block 25 to attach the label tail of the dovetail label 30 to the rear end of the irregularly shaped box 29 to complete the labeling of the dovetail label 30. Finally, it passes through the labeling detector. If the labeling detector detects that no label is applied, the rejection cylinder 26 drives the rejection head 28 to reject the irregularly shaped box 29 without label to the recycling bin 27. If the labeling detector detects that a label is applied, the rejection cylinder 26 does not move, allowing the dovetail box with label to enter the next process.

[0022] The above detailed description is a specific description of a feasible embodiment of the present utility model. This embodiment is not intended to limit the patent scope of the present utility model. All equivalent implementations or modifications that do not depart from the present utility model should be included in the patent scope of this case.
