Description

Technical Field

[0001] The present invention relates to the technical field of label production equipment, and in particular to an RFID label production control system and a control method thereof. Background Art

[0002] The existing RFID label production process generally involves continuous roll-to-roll processing of rolled label materials. The process includes laminating, die-cutting and testing. Generally, the process is firstly laminating, i.e. the Inlay layer, foam layer and backing paper layer are laminated together by a label laminating machine, then die-cutting, i.e. the required products are cut by a label die-cutting machine, and finally testing, i.e. the finished products are produced after the label testing machine passes the test. However, the label laminating machine, label die-cutting machine and label testing machine in the existing process can only complete one process independently, and each process requires at least one operator to operate. This production method has the following defects:

[0003] (1) Multiple processes are completed independently, increasing labor costs;

[0004] (2) Multiple processes can easily cause more static electricity to be generated on the surface of RFID tags, resulting in a lower yield;

[0005] (3) Multiple processes will waste too much coil material, resulting in increased production costs;

[0006] (4) Different equipment completes each process in a dispersed manner, which is not conducive to centralized control and improving production efficiency.

[0054] The reel 500 is installed on the label inspection machine 400 and is used to reel in the finished coil 20 that has undergone performance inspection.

[0055] The floating differential 600a is disposed between the label laminating machine 200 and the label die-cutting machine 300, and is used to control the relative running speed between the label laminating machine 200 and the label die-cutting machine 300.

[0057] See also Figure 3 The control method of the RFID tag production control system of the present invention comprises the following steps:

[0058] Step S10, when the system is initialized, the roll material 10 released by the unwinding roller 100 passes through the label laminating machine 200, the floating differential 600a, the label die-cutting machine 300, the floating differential 600b and the label inspection machine 400 in sequence, and is then reeled up by the reeling roller 500;

[0059] Step S20, the controller 700 controls the label die-cutting machine 300 to move, so that the floating roller 630b of the floating differential 600b drops to the lower position sensor 660b under the action of gravity, and the lower position sensor 660b is triggered and sends a signal to the controller 700, and the controller 700 controls the label die-cutting machine 300 to stop moving;

[0060] Step S30, the controller 700 controls the label laminating machine 200 to move so that the floating roller 630a of the floating differential 600a drops to the lower position sensor 660a under the action of gravity, and the lower position sensor 660a is triggered and sends a signal to the controller 700, and the controller 700 controls the label laminating machine 200 to stop moving, completing the system initialization;

[0061] Step S40, when the system starts working, the controller 700 starts the label detector 400, so that the floating roller 630b of the floating differential 600b rises to the middle position sensor 650b, and the middle position sensor 650b is triggered and sends a signal to the controller 700;

[0062] Step S50, the controller 700 starts the label die-cutting machine 300, so that the floating roller 630a of the floating differential 600a rises to the middle position sensor 650a, and the middle position sensor 650a is triggered and sends a signal to the controller 700;

[0063] In step S60, the controller 700 starts the label laminating machine 200 and controls the label laminating machine 200, the label die-cutting machine 300 and the label detecting machine 400 to run synchronously, so that the floating roller 630a of the floating differential 600a is kept near the center position sensor 650a and the floating roller 630b of the floating differential 600b is kept near the center position sensor 650b.

[0064] During the operation of the system, when the floating roller 630a of the floating differential 600a rises to the middle position sensor 650a, the middle position sensor 650a is triggered and sends a signal to the controller 700, and the controller 700 controls the running speed of the label die-cutter 300 to match the running speed of the label laminator 200, so that the floating roller 630a always runs at the sensor 650a. During the normal operation, due to external factors or system failure, the upper position sensor 640a is triggered and sends a signal to the controller 700, and the controller 700 controls the label die-cutter 300 and the label detector 400 to stop running. At this time, the label laminator 200 will continue to run, and when the floating roller 630a drops to the lower position sensor 660a, 660a is triggered and sends a signal to the controller 700, controlling the label laminator 200 to stop running. If the position sensor 660a is triggered and sends a signal to the controller 700 due to external factors or system failure during normal operation, the label laminating machine 200, the label die-cutter 300, and the label detector 400 are controlled to stop running. After the external factors are eliminated, the system is started, and the system will start the label die-cutter 300 and the label detector 400 in sequence according to the settings. When the position sensor 650a is triggered and sends a signal to the controller 700, the controller 700 controls the label laminating machine 200 to start running, and the system enters a stable operation state again.

[0065] During the operation of the system, when the floating roller 630b of the floating differential 600b rises to the middle position sensor 650b, the middle position sensor 650b is triggered and sends a signal to the controller 700, and the controller 700 controls the running speed of the label detector 400 and the running speed of the label die-cutter 300 to match, so that the floating roller 630b always runs at the sensor 650b. During the normal operation, due to external factors or system failure, the upper position sensor 640b is triggered and sends a signal to the controller 700, and the label detector 400 is controlled to stop running. At this time, the label laminating machine 200 and the label die-cutter 300 will continue to run. When the floating roller 630a drops to the lower position sensor 660a, 660a is triggered and sends a signal to the controller 700, and the label laminating machine 200 stops running. When the floating roller 630b drops to the lower position sensor 660b, 660b is triggered and sends a signal to the controller 700, and the label die-cutter 300 stops running. During normal operation, due to external factors or system failure, the lower position sensor 660b is triggered and sends a signal to the controller 700, controlling the label detector 400 and the label die cutter 300 to stop running. At this time, the label laminating machine 200 will continue to run. When the floating roller 630a drops to the lower position sensor 660a, 660a is triggered and sends a signal to the controller 700, and the label laminating machine 200 stops running. After the external factors are eliminated, the system will continue to run according to step S40.

[0066] The present invention connects the label compounding machine 200, the label die-cutting machine 300 and the label inspection machine 400 in series through the floating differentials 600a and 600b, so as to avoid the situation where the speed difference between the devices affects the quality of the label.

[0067] See also Figure 3 , the controller 700 is a schematic diagram of controlling a production line. Of course, the controller 700 can also control two production lines at the same time, such as Figure 4 As shown, the production efficiency is further improved and the production cost is reduced.
