Figure 3 is a view for explaining the concept of an operation of a pitch roll driving and coiler driving volume apparatus of an apparatus for manufacturing a promotional tab end of a can according to the present invention.
Best modes for carrying out the invention
The method for manufacturing a promotional tab end of a can according to the present invention will be described with reference to the accompanying drawings.
Figure 1 is a process flow chart explaining a method for manufacturing a promotional tab end of a can according to the present invention.
A pitch hole is formed at the tab coil (step 1: ST1).
The tab coil is stacked on the printing uncoiler and is passed through a printing line, and the tab coil is aligned to be in a printing line by connecting to a printing recoiler (step 2: ST2).
A printing is performed on the upper surface of the coil (step 3: ST3).
The tab coil is transferred by driving the pitch roll (step 4: ST4).
The ink printed on the transferred tab coil is UV-dried (step 5: ST5).
As the pitch roll is driven, the pitch hole sensor detects the pitch hole of the tab coil which is being transferred (step 6: STG).
As the pitch roll is driven, the encoder measures in real time the transfer speed of the tab coil which is being transferred (step 7: ST7).
An output signal is outputted by way of the pitch hole sensor (step 6), and the release time of the marking nozzle of the back surface of the coil is set depending on the measurement of the coil transfer speed of the coil of the encoder (step 7: ST7), and the marking on the back surface of the coil is performed (step 8: ST8).
The number of the pitch holes for the sake of transfers when driving the pitch roll is set in the pitch hole counter, and the pitch hole counter counts the number of the pitch holes of the tab coil, which is being transferred, by way of the pitch hole sensor (step 9: ST9).
The number of the set pitch holes and the tab coil are transferred to the pitch hole counter, and when the counted pitch hole numbers become same, the driving of the pitch roll stops (step 10: ST10).
As the pitch roll stops, the tab coil stops as well, and an upper surface printing signal is outputted (step 11: ST11).
The driving of the pitch roll continues until the number of the pitch holes counted during the transfer of the tab coil becomes same as the targeted value set in the pitch hole counter (step 12: ST12).
As the pitch roll is driven, the tab coil is transferred, and the uncoiler driving volume apparatus moves from the bottom dead point to the top dead point (step 13: ST13).
When the uncoiler driving volume apparatus moves out of the bottom dead point, the uncoiler increases or decreases the speed depending on the changes in the output signal of the driving volume apparatus, thus unwinding the tab coil (step 14: ST14).
As the pitch roll is driven, the tab coil is transferred, and the recoiler driving volume apparatus moves down from the top dead point to the bottom dead point (step 15: ST15). Here, the steps 13 and 15 are concurrently performed in sync with the driving of the pitch roll.
When the recoiler driving volume apparatus moves out of the top dead point, the recoiler increases and decreases the speed depending on the changes in the output signal of the driving volume apparatus (step 16: ST16).
Here, the steps 14 and 16 are concurrently performed in sync with the driving of the pitch roll.
As the above mentioned processes are repeatedly performed, the upper surface printing and coil back surface marking of the tab coil are completed, and the printing work-completed tab coil is inputted into the conversion press (step 17: ST17) for thereby finishing the production of the promotional tab.
Figure 2 is a side view illustrating an apparatus for manufacturing the promotional tab end of the can according to the present invention.
The tab coil unwound from a hole forming uncoiler 10 passes through a tab coil looping unit 12 after the pitch holes are formed by means of a hole forming press 11, and it is wound on a hole forming recoiler 10-1 via a washing apparatus 14 and a drier 15.
In terms of the pitch hole formation ST1, the hole forming recoiler volume apparatus 13 operates in sync with the speed of the hole forming press 11, so the tab coil can be wound with a constant tension by adjusting the driving speed of the hole forming recoiler 10-1.
The tab coil mounted at the printing uncoiler 20 is connected to the printing recoiler by way of a coil in-feeding apparatus 21, a printing apparatus
30, a UV radiation apparatus 40, a pitch roll 24 and a coil out-feeing apparatus 27, so a line alignment is performed for the purpose of beginning the printing process.
The printing is performed by the printing apparatus 30 on the upper surface of the line-aligned tab coil in conformity with the printing dots. When the operation of the printing apparatus 30 is finished, the pitch roll driving control 23 provides a driving output to the pitch roll 24 for thereby driving the pitch roll 24.
As the pitch roll 24 is driven, the tab coil is transferred, and the UV radiation apparatus 40 begins to operate so as to dry the ink printed on the upper surface of the tab coil which is being transferred. At the same time, the pitch hole sensor 22 detects the pitch holes of the tab coil which is being transferred, and a tab coil undersurface marking output signal is provided to an inkjet marking apparatus input apparatus 25. At the same time, the pitch hole sensor 22 detects the pitch holes of the tab coil which is being transferred and provides a pitch hole detection signal to the pitch hole counter 23-1. The pitch hole counter 23-1 generates a signal when the previously set target value becomes same as the number of the pitch holes detected by the pitch hole sensor 22, so the pitch roll driving control 23 stops the pitch roll 24.
As the pitch roll 24 is driven, the transfer of the tab coil starts, and at this time, the printing uncoiler volume apparatus 21-1 and the printing recoiler volume apparatus 27-1 operate in sync, and the printing uncoiler volume apparatus 21-1 unwinds the tab coil by adjusting the driving speed of the printing uncoiler 20, and the printing recoiler volume apparatus 27-1 winds the tab coil at a constant speed by adjusting the driving speed of the printing recoiler 20-1 for thereby maintaining a constant speed and tension, so the tab coil is transferred and wound.
The printing-completed tab coil is inputted into the conversion press 50, thus producing the finished promotional tab.
Figure 3 is a concept view for explaining the driving of the pitch roll and the operation of the coiler driving volume apparatus of the apparatus for manufacturing the promotional tab end of the can according to the present invention.
When the printing on the upper surface of the tab coil is finished, the pitch roll driving control starts driving the pitch roll, and at this time as the pitch roll is driven, the tab coil is transferred, and as the tab coil is transferred, in case of the uncoiler driving volume apparatus, it is moved upwards, and in case of the recoiler driving apparatus, it moves downwards. In sync with the above operations, the coiler driving volume apparatus increases or decreases the driving speed of the coiler for thereby driving the coiler. The pitch hole sensor detects the pitch hole and provides a pitch hole detection signal to the pitch hole counter, and the pitch hole counter drives the pitch roll until the number of previously set pitch holes become same as the number of the detected pitch holes, thus transferring the tab coil, and when the number of the previously set pitch holes is same as the number of the detected pitch holes, the driving of the pitch roll is stopped by the pitch roll driving control. At this time, the printing uncoiler driving volume apparatus drives the uncoiler until the bottom dead point, thus unwinding the coil, and the printing recoiler apparatus drives the recoiler until the top dead point for thereby winding the coil. In the above described manner, the tab coil is repeatedly transferred as much as the accurate transfer distance based on a stable tension, so the upper surface of the tab coil and the undersurface of the tab coil can be concurrently performed.
Modes for carrying out the invention
