The detecting element cooperation sets up holds in the palm foil board 7, hold in the palm foil board 7 and set up in the one side that detecting element was kept away from to goldleaf 5 for support goldleaf from the opposite side, hold in the palm foil board 7 and set firmly in the gilding press main part, guarantee that the goldleaf 5 of this position is level and smooth, tight, increased the accuracy of testing result, wherein detecting element adopts but not limited to current color sensor 4, camera etc. as long as can realize that the detection device that detects the goldleaf joint all is in the protective range of this application, the purpose utilizes optics or vision technique to detect the goldleaf joint.
And the foil pulling unit is arranged at the discharge end of the gold stamping plate and used for collecting the hot stamped gold foil 5, the collecting speed is controlled by the control unit, and the foil pulling unit adopts but is not limited to the existing roller way.
The detection unit is also correspondingly provided with a measurement unit for measuring the distance between the gold stamping plate and the detection unit. When the jumping is finished, the distance between the detection unit and the gold stamping plate needs to be considered, and the measurement unit adopts but is not limited to the existing steel ruler, tape measure and electronic distance measuring device.
The foil feeding unit includes:
the foil feeding rubber roller 1 is arranged on one side of the gold foil 5 and is attached to the gold foil 5;
and the foil feeding roller 2 is arranged on the other side of the gold foil 5, and is matched with the foil feeding rubber roller 1 to generate friction force during operation, the gold foil 5 is twisted and conveyed forwards, and the operation speed of the foil feeding roller 2 is controlled by the control unit.
The control unit can adopt an independent controller, such as a PLC, a PC or other control host, and can also utilize the controller of the hot stamping machine, and the main purpose is to realize intelligent detection of the gold foil joint and complete non-stop jumping.
The foil feeding unit further comprises a foil passing roller 3, and the foil passing roller 3 is arranged at the discharge end of the foil feeding roller 2. The foil passing roller 3 supports and guides the gold foil 5.
The detection and avoidance technique of the present invention will be further described with reference to the color sensor 4 as an example.
Detecting the principle of the gold foil joint:
first, the color sensor 4 needs to be set so that the color sensor 4 can normally distinguish the gold foil 5 from the tab on the gold foil 5 (when the gold foil 5 passes through the color sensor 4, the color sensor 4 does not perform any processing; when the gold foil tab passes through the color sensor 4, the color sensor 4 sends a signal to the controller).
When the foil feeding shaft rotates counterclockwise as shown in fig. 1, the gold foil 5 moves forward due to the friction of the foil feeding rubber roller 1 on the gold foil 5, and the gold foil 5 passes through the foil roller 3 and the foil supporting plate 7 during the movement. When the gold foil joint passes through the foil roller 3 and the foil supporting plate 7, it is detected by the color detection sensor.
The automatic evasion principle of the gold foil joint is as follows:
first the distance of the color sensor 4 from the first plate needs to be set. The color sensor 4 is then adjusted so that the color sensor 4 can distinguish between a normal gold foil 5 and a joint on the gold foil 5.
In the process of carrying out normal hot stamping on a product, the color sensor 4 detects a signal of the gold foil connector at a certain moment, the signal of the sensor is transmitted to the gold stamping PC at the moment, and the PC opens the gold foil connector to avoid the state. Because the position of the color sensor 4 away from the first gold stamping plate is set, the corresponding foil pulling distance is deducted from the distance after foil pulling each time, and when the joint position does not meet the foil pulling distance enough, the gold foil 5 jumps one big step at high speed to move the joint position to the outside of the host platform, so that the joint position is ensured not to be subjected to hot stamping.
The leap step method can be simply understood that when the distance between the gold foil joint and the gold stamping plate is close, the control unit (PC) controls the foil pulling unit and the foil feeding unit to operate quickly, and when the gold foil joint is subjected to next hot stamping of the gold stamping plate, the gold foil joint is fed to the other side, so that large leap steps are realized, shutdown processing is not needed, and manual participation is not needed, but the method has certain defects, namely gold foil can be wasted, and aiming at the defects, an automatic avoiding method is specially developed, so that under the condition that shutdown is not realized, manpower is liberated, the gold foil is saved, and the utilization rate of the gold foil is effectively improved, and the specific method is as follows:
acquiring position information of the gold foil joint by using a detection unit;
calculating the real-time distance between the gold foil joint and the gold stamping plate by combining the distance between the detection unit and the gold stamping plate and the foil feeding times and the single foil feeding length after the gold foil joint information is detected;
when the real-time distance cannot meet the foil feeding distance;
and controlling the foil feeding unit and the foil pulling unit of the gold foil 5 to run fast, and executing skip operation to move the gold foil joint to the discharging end of the gold stamping plate before the next work of the gold stamping plate.
The position signal of the gold foil tie is detected by means of a detection unit, wherein the detection unit employs, but is not limited to, existing color sensors 4, visual probes, etc., with the purpose of detecting the gold foil tie using optical or visual techniques.
The jumping operation comprises the calculation of the length and the speed of the foil;
wherein, the calculation of the length of the foil is to manually calculate the length of the foil, and the specific formula is as follows:
foil drawing length is equal to the maximum hot stamping length in the paper feeding direction of the gold stamping machine plus the default gold foil joint length;
and (4) average foil drawing speed is equal to the length of the foil drawing/working period of the bronzing plate.
The calculation of the length of the foil is also carried out automatically, and the specific formula is as follows:
foil drawing length is equal to plate length of all gilding plates, interval of all gilding plates and default gold foil joint length
And (4) average foil drawing speed is equal to the length of the foil drawing/working period of the bronzing plate.
The method is further explained with reference to examples:
first the distance of the color sensor 4 from the first plate needs to be set. The color sensor 4 is then adjusted so that the color sensor 4 can distinguish between a normal gold foil 5 and a joint on the gold foil 5.
In the process of carrying out normal hot stamping on a product, the color sensor 4 detects a signal of the gold foil connector at a certain moment, the signal of the sensor is transmitted to the gold stamping PC at the moment, and the PC opens the gold foil connector to avoid the state. Because the position of the color sensor 4 away from the first gold stamping plate is set, the corresponding foil pulling distance is deducted from the distance after foil pulling each time, and when the joint position does not meet the foil pulling distance enough, the gold foil 5 jumps one big step at high speed to move the joint position to the outside of the host platform, so that the joint position is ensured not to be subjected to hot stamping.
And when the jumping operation is executed, calculating the length of the foil:
(1) manually calculate foil pull pattern:
the length L of the big step is the maximum hot stamping length in the paper feeding direction of the gilding press plus the default gold foil joint length)
(2) Automatically calculating a foil drawing mode:
when the foil drawing is automatically calculated, the required step length can be calculated according to the data on the parameters of the automatically calculated foil drawing.
Large step length L ═ Σ (plate length of all gilding plates + interval of all gilding plates) + default gold foil joint length
Calculating the average foil drawing speed:
since the length of the foil is suddenly increased to a great extent, the corresponding average speed of the foil is also increased to a great step length L to allow the gold foil 5 to be completely removed and pulled away in one cycle. For example: when the current machine speed is 7200 sheets/hour, the one-turn time is 3600/7200 ═ 0.5s, and the foil feeding time is 0.5/2 ═ 0.25s, then the foil feeding and foil pulling actions need to be completed in 0.25s, that is, the gold foil 5 conveying action with the length of large step length L needs to be completed in 0.25s, which is the foil feeding speed corresponding to the completion of the large step length.
