EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated in detail with reference to drawings.

1 is a line configuration diagram showing the configuration of a cylinder roll printing design tap end production apparatus using a pilot hole of a tap coil according to an embodiment of the present invention.

Referring to this, in order to accurately match the pitch of design printing and tap forming prior to the start of the printing process of the tap coil 2, the tap coil 2, which is attached to the uncoiler 4 and wound in a roll form, is supplied to the tap coil. The feeder 6 is introduced into the pilot hole drilling press 8 at a constant speed so that the pilot hole 201 (see Fig. 4) is drilled at a constant shape and interval.

The pilot hole punching press 8 has one pilot punch (not shown) and a plurality of pilot pins located on a continuous straight line in view of the one-lane tab forming. (Not shown) and a tap coil pilot hole integrally formed with a reform punch to flatten protrusions that may occur on the lower surface of the tap coil when the pilot hole 201 is drilled by the mentioned pilot punch. A drilling die set is provided.

At this time, each of the pilot hole punch, the pilot pin, and the reform punch are provided in accordance with the number of lines of the tap coil to be printed and marked on the back surface. In addition, the rear end of the pilot hole punching press 8 is provided with a centuries 10 and a flush dryer 12 for cleaning the surface of the perforated tap coil.

The tap coil, which has been rinsed and dried through the centuries 10 and the rinsing dryer 12, has a pitch roll in feeder for printing and molding the design at the same pitch and position in the tap coil printing process and the tap forming process. 14) to the cylinder roll printing machine (16).

The tap coil passing through the pitch roll in feeder 14 is introduced into the cylinder roll printing machine 16 at a constant pitch, and the cylinder roll printing machine 16 performs a printing process and a drying process for the tap coil. After that, the tap coil 2 is wound by the recoiler 22 while maintaining a constant pitch through the pitch roll out feeder 18 to complete the printing process.

At this time, the tap coil feed feeder 8 and the tap coil out feeder 20 identify the tap coil 2 conveyed by the continuous driving of the pilot hole punching press 6 and the recoiler 22 on its surface. It serves as a looper to connect with the cylinder roll printing machine 16 for printing a pattern.

The tap coil having completed the wound printing process is mounted on an uncoiler (not shown) for the conversion press for tab forming, and then the tab is formed by the conversion press (not shown). At this time, the pilot punching process of the conversion press is removed and a plurality of pilot pins of the tab die set are applied to the pilot hole 201 of the tap coil 2 which is pre-drilled before the printing process by the pilot hole drilling press. The pitch of the tab forming process and the printing process is always kept the same.

2 is a configuration diagram of a tap coil pitch roll feeder and a cylinder roll printing machine according to an embodiment of the present invention, and FIG. 3 is a partially enlarged side view illustrating an enlarged portion of the cylinder roll printing machine shown in FIG. 2, and FIG. 4. Is an enlarged side view of a part of a cylinder roll printing machine using a printing cylinder roll provided with an elastic member or a pilot pin die hole instead of the pitch guide pin backup roll according to the present invention.

Referring to this, a tap coil pitch roll 147 is mounted to the pitch roll infeed machine 14, and a pitch guide pin 142 is mounted to protrude along the outer circumferential surface of the tap coil pitch roll 147. Since the pitch guide pin 142 is tapered at a diameter smaller than that of the upper end, the pitch guide pin 142 can cope with a minute position change or a length change due to thermal expansion or thermal contraction during the transfer of the tap coil 2. 2) is passed between the pitch roll 147 and the pitch backup roll 143 to be conveyed at a constant pitch.

Further, the perforated pilot hole 201 of the tab coil 2 is printed with a back-up roll with a pitch guide pin 142 and an elastic member (not shown) or a pilot pin die hole 201 such as silicone or rubber. As the tap coil 2 is transported between the cylinder rolls (not shown), the occurrence of the accumulated tolerance is prevented, and the design can be printed at the correct pitch and position.

Accordingly, the pitch guide pin 142 attached to the tap coil pitch roll 147 is alternately inserted into and detached from the pilot hole 201 previously drilled in the tap coil as the tap coil pitch roll 147 rotates. Prevents the occurrence of cumulative tolerance of the printing position due to length change due to thermal expansion or thermal contraction of the tap coil, and the tap coil 2 is transferred from the pitch roll in feeder 14 to the pitch roll out feeder 18. While the tap coil is transferred between the backup roll 143 with the pitch guide pin 142 and the printing cylinder roll with the elastic member such as silicon or rubber or the pilot pin die hole, the occurrence of accumulated tolerance without stopping in the whole process is prevented. This prevents accurate printing.

In this case, the tap coil 2 is transported by the driving of the pitch roll 147, and is not transported by the friction force between the pitch roll 147 and the pitch backup roll 143. In addition, it is preferable that the roll surface of the pitch back-up roll 143 is generally made of an elastic material such as silicone or rubber.

As shown in FIG. 3, the elastic member such as silicon or rubber or the pilot pin 163 are protruded to the outer surface of the cylinder roll printing machine 16 so as to be in close contact with the pilot pin 163. The tap coil 2 may be transferred to prevent the accumulated tolerance of the tap coil by the pilot pin insertion hole (not shown) of the backup roll 164.

On the other hand, a pilot pin insertion hole (not shown) of a predetermined size is formed in the outer circumferential surface of the cylinder roll printing machine 16, and the pile is formed on the outer surface of the backup roll 164 in close contact with the outer surface of the cylinder roll printing machine 16. The lot pin may be formed to protrude.

Accordingly, the tab coil 2 can print a constant pattern on the outer surface of the tab coil 2 through the cylinder roll printing machine 16 while passing through the pitch roll in feeder 14, and the cylinder The pattern printed by the plurality of dryers 166 provided in the roll printer 16 is dried, and is transferred to the pitch roll out feeder 18.

At this time, the present invention can prevent the occurrence of cumulative tolerance even by the back-up roll 164 mounted in close contact with the cylinder roll printer 16 and its lower portion, as well as more accurate printing, transfer of the tap coil (2) This becomes possible.

5 is a view showing a tap coil processed according to the design tap end manufacturing process according to an embodiment of the present invention, Figure 6 is a process diagram showing a design tap end manufacturing process according to an embodiment of the present invention.

First, the tap coil wound and mounted on the uncoiler 4 in the form of a roll is introduced into the pilot hole punching press 8 at a constant speed, so that the pilot hole 201 is drilled at intervals of a circular or square shape. (Step 100: ST-100).

The tap coil punched by the pilot hole drilling press 8 is sequentially introduced into the centuries 10 and the water washing dryer 12 by the tap coil feed feeder 6 to perform washing and drying processes.

Then, the pitch roll-in feeder 14 is fed into the cylinder roll printing machine 16 so that the design is printed and molded at the same pitch and position in the tap coil printing process and the tab forming process (step 200). : ST-200).

At this time, the pitch guide pin 142 attached to the tap coil pitch roll 147, the guide pin attached to the pitch backup roll, and the pilot pin 163 in the printing cylinder roll 162 are pre-drilled to the tap coil. It is inserted into the pilot insertion hole (not shown) formed in the lot hole 201 and the backup roll 164 to prevent the occurrence of the accumulated tolerance of the printing position due to the length change due to thermal expansion or thermal contraction of the tab coil.

At this time, a pilot insertion hole (not shown) is formed on the outer surface of the cylinder roll printer 162, and a pilot pin (not shown) is formed on the backup roll 164 mounted in close contact with the bottom surface of the cylinder roll printer 162. Printing may be performed while transferring (2) to the rear end (ST-300, ST-400).

The tap coil introduced into the cylinder roll printing machine 16 at a constant pitch is dried by a dryer () provided inside the cylinder roll printing machine 16 and then transferred to the rear end thereof (step 500: ST-500).

Thereafter, in the state of maintaining a constant pitch with the pitch roll out feeder 18, it is wound by the recoiler 22 to complete the printing process (step 600: ST-600).

The tap coil having completed the wound printing process is mounted on an uncoiler (not shown) for the conversion press for tab forming, and then uncoiled (step 700: ST-700) to form the tab by the conversion press. . At this time, the pilot punching process of the conversion press is removed and a plurality of pilot pins of the tab die set are applied to the pilot hole of the tap coil pre-drilled before the printing process by the pilot hole punching press, thereby forming the tab forming process and printing. The pitch of the process is always kept the same (step 800: ST-800).

On the other hand, the design tap end manufacturing apparatus and the method of the pre-printing post-forming method using a pilot hole according to an embodiment of the present invention is not limited to the above-described embodiment and various within the scope not departing from the technical gist. Changes are possible.

As described above, the apparatus for producing a design tap end of the pre-printing post-forming method using the pilot hole according to the present invention, and the method thereof, are applied to the tap coil in advance in the same manner as the pitch of the tap forming process in the conversion press in the pre-printing step. By drilling the pilot hole to complete the printing and tab forming process, it is possible to prevent the position of the printed design in the printing process and the forming process from deviating from the desired tab position. In particular, in addition to the pitch roll infeeding machine and the pitch roll out feeder for compensating the tap coil tolerances by the pilot hole and the pilot pin, the pilot hole and the pilot are also used for the cylinder roll printing machine and the back-up roll that comes in close contact with the printing machine. Forming the pins individually has the effect of allowing more accurate movement of the tap coil and printing of a specific pattern on the tap coil.
