Background
The existing two-dimensional code label detection equipment generally has two implementation modes. The first method is to detect the effectiveness of the two-dimension code of the label, then to make logical mark through software system, and the obtained database is uploaded to the labeling system. The second is to apply a mark to an invalid label. In either case, the invalid label is left on the label paper, so that when the label is used, some additional collection and verification method has to be adopted to identify the invalid label and then distinguish the invalid label for use. For example, the label detected by the first method can only be labeled by a machine (because the two-dimensional code cannot be identified by human eyes), and the label is secondarily identified by using the original detection database and visual identification equipment. The second method detects and marks invalid labels, and when the labels are pasted manually, the smeared invalid labels are recognized by naked eyes, so that blind pasting cannot be realized.

In particular, in order for the public to understand the technical solution of the present application, the following detailed description is made on each component with reference to fig. 1 and 2;
the package two-dimensional code label removing system mainly comprises four parts, namely [ A industrial control computer ], [ B label stripping machine ], [ C label rewinder ], [ D visual detection equipment ]. Among them, A, B, C, D four core devices in some embodiments may be fixed on the [ E stage ].
[ A Industrial computer ]: the X86 architecture industrial control computer is connected with and controlled by a label stripping machine B, a label stripper C and a visual detection device D through software and hardware. The label detection and invalid label elimination device controls all parts of equipment to complete label detection and invalid label elimination, and is also responsible for outputting processed package label acquisition data.
[ B Label stripper ] (left dotted inner part, no D part): the label stripping machine mainly comprises four parts, namely a label stripping machine controller, a label stripping machine paper feeding wheel, a label stripping machine stripper and a label stripping machine recovery wheel. It can realize the stripping of the label of the roll, it is the most important component of the industrial labeling machine, here we use it to realize the stripping operation of the invalid label.
[ tag peeler controller ]: the control host machine is a B label stripping machine and consists of a PLC controller and an operation panel. It has two modes of operation, one is manual mode and the other is programming mode. In the manual mode, the user performs an operation of label peeling through the operation panel. Under the programming mode, the computer can be connected with an upper computer through an RS232 interface for programming control. We here are working in programming mode. The A industrial control computer is connected with the RS232 interface, and the A industrial control computer controls the label stripping machine to perform actions such as paper feeding action, label stripping and the like through instructions.
[ tag peeler paper feed wheel ]: it is a passive wheel used for placing the roll label to be detected.
[ tag peeler ]: the initial label paper of the packaged label to be detected is connected to a stripper, the stripping head of which is connected to the recovery paper roll of the [ seventh ] label rewinder recovery wheel. It is used to receive the control command of industrial computer and to strip and paste the invalid label onto the recovered paper roll of label back-up machine.
[ recovery wheel of label stripping machine ]: it is a driving wheel driven by a stepping motor. It has two functions, one is used as power source for paper feeding action of label stripping machine, and the other is used for rewinding label processed by detecting and removing ineffective label into label roll.
[ D visual detection device ]: the first part is a photoelectric trigger, and a trigger signal output line of the first part is connected to a trigger signal line of the second part of the industrial cameras. The second part is the industrial camera, which we set as a hardware signal trigger (i.e. signal trigger line is active). The industrial camera is connected with the A industrial control computer through a gigabit Ethernet. The visual detection device has the functions that when one label passes through the stripping head of the label stripper, the photoelectric trigger triggers the industrial camera to take a photo, and then the industrial camera transmits the image to the industrial control computer A for processing.
[ C Label rewinder ] (right dotted inner part): which may be referred to in the market as a label rewinder or a rewinder, can be used to rewind a roll label onto another winding core. The user typically uses it as a label rewind operation, but here we use it as a poster carrier generator for a label peeler. When the label stripper works, a moving object passes through the stripping head of the label stripper and then takes the stripped label away, and the rewinding machine can simulate the operation.
[ tag rewinder controller ]: the control host machine is a C label rewinder and consists of a PLC controller and an operation panel. It has two modes of operation, one is manual mode and the other is programming mode. In the manual mode, the user performs an operation of rewinding the label through the operation panel. Under the programming mode, the computer can be connected with an upper computer through an RS232 interface for programming control. Here, we work in the programming mode, connected with RS232 interface through [ A industrial control computer ], and control the paper feeding action of the label rewinder through the instruction
[ tag rewinder recovery wheel ]: it is a driving wheel driven by a stepping motor. It has two functions, one is used as power source of label rewinder, and the other is used for recovering the roll paper with invalid label.
[ paper feed wheel of label rewinder ]: it is a driven wheel. Where it is used to place roll-fed printing paper, which may be blank paper or waste paper, since here it only serves as a posting support for the stripped off non-functional labels.
[ E stage ]: in some embodiments, the device can be designed as a stainless workbench for fixing A, B, C, D four working devices, so that the whole device is integrated.
The use process comprises the following steps:
1. the operator creates a record to be detected in the industrial computer A, and the computer generates a volume number for the record.
2. According to the length of the label paper of the roll label to be detected, inputting [ A industrial control computer ], sending an instruction to [ B label stripping machine ] from [ A industrial control computer ], initializing the stepping parameters of the stepping motor, and initializing the stepping parameters of the [ C label rewinder ] stepping motor. The step unit length of the two devices is made to be the same as the label paper length (two-dimensional code label unit length).
3. The package label to be detected is loaded to the paper feeding wheel of the label stripping machine, the initial paper is connected to the stripper of the label stripping machine and the recovery wheel of the label stripping machine, and the two wheels are connected together through the package label paper, as shown in the line part of the label stripping machine in figure 1B. Then an empty winding core (namely the recycling winding core mentioned above) is arranged on the recycling wheel of the label stripping machine.
4. A roll of blank printing paper (i.e., an invalid label feed core provided with an invalid label recovery roll paper as described above) is set to [ C ] a label rewinder feed wheel, and the start paper is set to [ C ] a label rewinder recovery wheel, as shown in the line portion of [ C ] of fig. 1. Then an empty core (i.e. the invalid label recycling core described above) is mounted on the [ label rewinder recycling wheel ]. (remark: after the first coiled two-dimensional code label to be detected is completely detected, the recovery roll paper of the invalid label may not be used up, in this case, the 4 th step is not necessary, and if the blank printing paper is not used up, the step can be omitted.)
5. And starting the label stripping machine to enter a single-step paper feeding state through the industrial control computer A. That is, the label paper is made to advance one by one according to a certain frequency.
6. When the label passes through the stripper of the label stripper, the photoelectric trigger of the visual detection device is triggered, then the industrial camera is triggered to take a picture, and the picture is transmitted to the industrial computer A.
And 7, processing software of the A industrial control computer, and decoding the two-dimensional code of the image. If the two-dimensional code is decoded successfully, recording a code value, and adding 1 to a correct calculator of the industrial personal computer; if the operation fails, a command is sent to the tag stripping machine controller, and the tag stripping machine controller controls the tag stripping machine stripper to execute stripping action. Meanwhile, [ A industrial control computer ] sends an instruction to [ tag rewinder controller ], [ tag rewinder controller ] executes the rewinding action and executes the stepping of the length of four tags. Thus, the one invalid label is stuck to the printing paper of the C-label rewinder. And adding 1 to an error counter of the industrial control computer. The working principle of peeling off the pasted head is shown in fig. 2:
when the industrial control computer sends a command to the label stripping machine controller to control the label stripping machine stripper to execute the stripping action, the label stripping machine stripper can roll the invalid label to the position of the labeling head (namely the triangular front end of the upper drawing) to ensure that the label is in a bonding state. The label on the label head is in a half-peeling state as shown in the figure, namely about one of three parts of the label is peeled off, the label has a glue sticking surface facing downwards and is in micro-contact with printing paper arranged on a paper feeding wheel of a label rewinder;
after the industrial control computer controls the peeling action, a command is sent to a label rewinder controller to control the label rewinder recovery wheel to rotate anticlockwise so as to drive a label rewinder paper feeding wheel to rotate clockwise and further drive the printing paper on the label rewinder to advance, and the labels in an upper half peeling state of the label peeler are drawn and stuck to the printing paper due to the forward power of the printing paper, and a blue convex part (one convex part represents one label) is arranged on a connecting line (the connecting line represents the printing paper) diagram in the upper diagram; theoretically, the blank roll paper advances by one two-dimension code label unit length, the invalid two-dimension code can be automatically attached to the blank roll paper, but the unit stroke of recovering the roll paper by the invalid label is improved to be larger than one two-dimension code label unit length, and certain compensation can be provided when the invalid two-dimension code label slips from the recovered roll paper by the invalid label; of course, the unit length of a two-dimensional code label in the application is not the length of the two-dimensional code label; when the two-dimension code labels are put into different finished products of the two-dimension code labels in a coiling mode, gaps between the two-dimension code labels are also required to be considered.
8. And (5) circularly executing the steps of 5-7 by the system until all the roll of label paper is rewound to an empty roll core of a recovery wheel of the label stripping machine, and marking the detection record as a finished state by an operator at an industrial control computer (A).
9. And (4) taking off the finished label from the recovery wheel of the label stripping machine by an operator, and marking the roll number on the industrial control computer on the label.
10. The operator repeats the operations 1-9 and additional roll labels are detected. And finally, generating a detection report of all the volumes by the [ A industrial control computer ]. The detection report comprises data such as the volume number of the label, the count of the valid label, the count of the invalid label, the code value of the valid label and the like. The detection data may be provided for use by the customer of the tag.
The four important devices [ A industrial control computer ], [ B label stripping machine ], [ C label rewinder ], [ D vision detection device ] used in the method can be selected to carry out secondary assembly integration. For example, the label peeler and the label rewinder are commercially available devices, and the label peeler and the label rewinder of shenzhen, kongmn technologies, ltd, for example, are one of our model selection devices.
Theoretically, any type of B label stripper and C label rewinder which have programmable capacity (namely can be controlled by software on an industrial personal computer through RS232 or other common industrial control interfaces) on the market can be used as model selection equipment of the system. However, it should be noted that, for those skilled in the art, it is necessary to design a corresponding working platform E for fixing and installing equipment according to the structures of different [ B tag peeler ], [ C tag rewinder ], and to arrange installation screw holes at corresponding positions on the platform; it should be noted that the visual inspection of the label is the key of the whole set of inspection effect. The measure is that a high-resolution industrial camera is adopted, and the resolution is required to be not less than 1024 by 1024 pixels; of course, in some embodiments, optimization of the decoding algorithm of the two-dimensional code may also be performed to ensure that it is preferable to make the detection error rate lower than 2 parts per million.
Compared with the prior art, the application has the following beneficial effects:
1. the method and the device really solve the problems of detection and physical elimination of the package label; original functions of the label stripping machine and the label rewinder are ingeniously utilized and combined, and full-automatic stripping of invalid labels is achieved.
2. The system is low in cost and suitable for popularization by adopting universal equipment on the market to integrate the system, so that the system is low in cost.
3. Simple operation and convenient use.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
