Detailed Description
The present invention is further described below in conjunction with the drawings and the embodiments so that those skilled in the art can better understand the present invention and can carry out the present invention, but the embodiments are not to be construed as limiting the present invention.
Referring to fig. 1-3, a simplified labeling accuracy detection method according to the present invention is shown. The detection method comprises the following steps:
sticking a double-layer label on the package; lower floor's label 2 in the double-deck label is the product label, and upper label 3 is for detecting the label, and this embodiment sets up upper label 3 and is transparent label to do not influence the show of lower floor's label 2 information. The upper layer label 3 can be the same as the lower layer label 2 in shape and can also be different from the lower layer label 2 in shape; considering the difficulty of preparation, upper label 3 sets up to square in this embodiment, and no matter what kind of shape size lower label 2, upper label 3 can be same kind to avoid detection device's change, improved the commonality. While the center of the upper label 3 coincides with the center of the lower label 2 in order to ensure that the position of the upper label 3 can represent the position of the lower label 2. Further, if the lower label 2 is also square, the four sides of the upper label 3 are parallel to the four sides of the lower label 2. Considering that the space of the labeling position on the product 1, especially on the electronic product, is small, if the upper label 3 is large, there is a possibility that there is not enough space on the product 1 to spread the upper label 3, so the upper label 3 may be the same size as the lower label 2, or smaller than the lower label 2; if the size of the upper layer label 3 is the same as that of the lower layer label 2, the lower layer label 2 is easy to take away when the upper layer label 3 is torn off; therefore, in the embodiment, the size of the upper layer label 3 is smaller than that of the lower layer label 2, and the lower layer label 2 and the product 1 can be further compressed when the detection is carried out, so that the lower layer label 2 is prevented from being mistakenly taken off. When in processing, the lower layer label 2 and the upper layer label 3 are respectively pasted on the release film in a transferring way, if the size of the upper layer label 3 is the same as that of the lower layer label 2, the upper layer label 3 and the lower layer label 2 are simultaneously cut by a die cutter; if the size of upper label 3 is less than lower floor's label 2, then utilize the die-cutting rule earlier with upper label 3 and lower floor's label 2 simultaneously cut out lower floor's label 2 shape, carry out the cross cutting to upper label 3 again.
Specifically, for detecting the rubberizing precision, adopt the profile modeling edging head 4 the same with 3 periphery shapes of upper label, along the periphery of 3 theoretical positions of upper label compaction downwards. If the position that double-deck label is attached is accurate, be located theoretical position promptly, then the outer fringe of profile modeling edging head 4 laminating upper label 3, and do not press upper label 3, this moment, because upper label 3 is not stressed, consequently can easily be torn. Especially, in this embodiment, upper label 3 is less than lower floor's label 2, and profile modeling edge pressing head 4 pushes down when, can push down lower floor's label 2, further prevents to take away lower floor's label 2 when tearing off upper label 3. If the double-layer label is attached to be twisted, the upper layer label 3 deviates from the theoretical position, and at the moment, a part of the upper layer label 3 can be pressed when the profiling edge pressing head 4 presses downwards, so that the upper layer label 3 cannot be smoothly taken off.
When tearing upper label 3, the control is got the power of tearing of mark, guarantees that the power of tearing to upper label 3 is even. When the double-layer label is twisted, because the shape of the copying edging head 4 is consistent with that of the upper-layer label 3, when the copying edging head 4 presses downwards, one part presses the upper-layer label 3, the other part does not press the upper-layer label 3, if the label is torn from the side which is not pressed, the part of the label can be uncovered by using smaller force, and the other corners of the upper-layer label 3 are pressed by the copying edging head 4 and cannot be lifted along with the lifting of the upper-layer label 3, and at the moment, if the tearing force is increased, the upper-layer label 3 is possibly torn to cause false detection. Therefore, the tearing force is controlled to be uniform, the upper label 3 which is not pressed can be torn, and when the upper label 3 is pressed, the upper label 3 is torn to meet resistance, and the upper label 3 is separated from the label taking head. In this embodiment, the adhesion between upper label 3 and lower label 2 is less than the adhesion between lower label 2 and the packing to ensure that even if the size of upper label 3 is greater than or equal to lower label 2, lower label 2 will not be taken away when upper label 3 is peeled off. Further, to prevent the upper label 3 from being torn, the upper label 3 is made of a tear-proof material, such as PVC. The mark of getting in this embodiment is the vacuum chuck of labelling promptly, and for the tearing power of control mark head is invariable, vacuum chuck and upper label 3 back of contacting start vacuum apparatus suction, make and produce the negative pressure in the sucking disc, hold upper label 3 back, stop the suction. For further control to the power of tearing of upper label 3, connect on getting the head and draw pressure sensor, when tearing upper label 3, through drawing the action that pressure sensor control got the head. For example, the tearing strength is set to F0If the actual tearing force is less than F0Taking the header to lift so as to tear up the upper layer label 3; if it isIn the lifting process of the header taking head, the pulling force detected by the pulling and pressing force sensor is greater than F0If the label is not qualified, the upper layer label 3 is pressed by the profiling edge pressing head 4, the label is stopped to be torn, the upper layer label 3 is opened by taking the head, and the label is judged to be unqualified.
The label taking head which is subjected to label tearing operation is checked, whether a label exists under the label taking head is detected, and whether the label exists can be directly obtained according to the fact that the label taking head is a vacuum sucker or not. If the label exists under the label taking head, the position of the double-layer label is the predicted position, namely the label is attached to be qualified, and the package is conveyed to a qualified product channel. If no label is placed under the label taking head, the label cannot be taken off by the tearing force of the label taking head, or the tearing force of the label exceeds the set tearing force, the upper layer label 3 is pressed by the profiling edge pressing head 4, namely the double layer label is twisted, and the package is conveyed into a defective product channel at the moment.
The labeling precision is detected by the detection method, the label taking head absorbs the label on the label material belt, then the absorbed label is directly adhered to the surface of the product 1, the label taking head is lifted, the copying edge pressing head 4 is pressed downwards, and the interference between the copying edge pressing head 4 and the label taking head is prevented. After the copying edge-pressing head 4 is compacted, the upper layer label 3 is absorbed by the picking head, and the upper layer label 3 can be picked from the surface of the lower layer label 2 under the condition that the upper layer label 3 is not pressed by the copying edge-pressing head 4; when the upper label 3 is pressed by the copying and hemming head 4, the upper label 3 cannot be removed because there is resistance to the suction of the upper label 3 by the label taking head. Finally, whether the label is attached to be qualified or not is judged by judging whether the upper layer label 3 exists on the header. The tearing of the upper layer label 3 is realized by the label taking head, the detection of labeling precision can be realized only by additionally arranging the profiling edge pressing head 4, the structure is simple, the cost is low, the operation is convenient, the utilization rate of the existing equipment is high, the detection is directly carried out after labeling, the deviation of the direction of the product 1 in the transferring process, the label deflection and the labeling reject ratio are avoided. The profiling edging head 4 can be arranged on one side of the product 1, and a double-layer label is compacted in a turning mode; it can also be arranged above the product 1, by pressing down a double label.
When the label is pasted, if the double-layer label is twisted, the position change of the pasting reference point is minimum, and the farther the distance from the reference point is, the larger the deviation degree of the double-layer label is. In order to ensure that the double-layer label can be compacted by the profiling edging head 4 even if the double-layer label has a slight deviation, as a preferred embodiment of the invention, the double-layer label is attached to the package by taking one corner of the lower layer label 2 as a positioning reference, and the profiling edging head 4 compacts the periphery of the upper layer label 3 at least corresponding to the opposite corner of the lower layer label 2. When one corner of the lower layer label 2 is used as a positioning reference, the opposite angle of the corner is farthest away from the corner, if the double-layer label is twisted, the offset of the opposite angle position is the largest, and when the profiling edge pressing head 4 presses the periphery of the upper layer label 3 along the opposite angle, the offset upper layer label 3 can be pressed certainly. Further, when the width of the lower surface of the copying edge pressing head 4 in contact with the double-layer label is wide, and under the condition that any one of the double-layer label and the copying edge pressing head 4 is uneven, the copying edge pressing head 4 may not completely compact the double-layer label, and especially under the condition that the offset of the double-layer label is small, if the copying edge pressing head 4 does not compact the upper-layer label 3, detection omission may be caused. In order to solve the problem, the width of the lower surface of each side of the profiling edge pressing head 4 is 1/20-1/10 of the width of the upper label 3. Because the width of profile modeling edge pressing head 4 is narrow, consequently little with the area of contact of double-deck label, under the same condition of pressure, the lifting surface area is less, and pressure is big more, when being pushed down the back, gets the mark head and want to tear upper label 3 off, then needs bigger power just can accomplish, gets under the unchangeable condition of mark head tearing force, judges more easily whether the label is askew to turn round. Furthermore, in order to give the mark head and dodge the space, the lower extreme leanin of profile modeling edging head 4, the upper end is outside dodge to the projection plane of 3 theoretical positions of upper label is kept away from on 4 upper portions of profile modeling edging head, when getting mark head and tearing upper label 3, can not interfere with profile modeling edging head 4.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications derived therefrom are intended to be within the scope of the invention.
