Description

Pressure Taping Machine {PRESSURE TAPPING MACHINE}

The present invention is to fix the end of the iron plate to the coil outer diameter so that the end portion (end of the iron plate) of the coil is not released when winding the iron plate produced in the annealing line, recoiling line, plating line, etc. of the steel mill cold rolling mill in the form of a coil A pressure taping machine is used to automatically tape a filament tape to be made.

In general, the iron plate finally produced in the cold rolling mill is shipped in the form of a coil, which is bundled with a steel band or taped to prevent the coil from being released.

The tape taping standard is 0.15mm ~ 0.85mm in thickness, and when banding with steel band, marks are made on the steel plate, so the tape is taped by inserting a filament tape with strong adhesion and tensile stress into the taping machine. When the winding was completed, the taping work was possible only when the coiling machine, the transfer car carrying the coil, and the walking beam were moved to the fixed skid that the taping machine could tap.

That is, as shown in FIGS. 1 and 2, in order to tape the taping machine 2 to the lower left side of the central part of the coil 1 so that the outer diameter of the coil 1 on which the iron plate is wound is not released. As the coil is wound around the reel 3 as described above, the rotational speed of the reel 3 becomes slow and the pressure roll 4 descends to the upper surface of the outer diameter of the coil 1 to stop the end of the iron plate (coil). To the end, as shown in (b) of FIG. 2, the end of the iron plate passes through the portion pressed by the pressure roll 4.

At this time, since the coil 1 has a pulling force in the reel 3, when the iron plate is sheared, the end of the iron plate is pulled in the reel 3 direction by the pulling force, so that the coil wound tightly is released. In order to prevent the pressure roll 4 must be sheared while pressing the upper surface of the coil.

However, as shown in (a) of FIG. 1, the end of the iron plate should be stopped at a specific position (8 o'clock in the clockwise direction) (P), so that the end of the iron plate is excessively over the point where the pressure roll 4 is pressed. Bounces and collides with the belt wrapper 5 due to its own weight and pulling force.

In addition, even if the end of the iron plate is stopped in the specific position (P) fixed by the coiling car 6 and the transfer car (not shown) and the walking beam (not shown) can be taped machine 2 The end portion of the coil continues to be struck down by its own weight until it reaches the skid 7, and therefore is likely to be wrinkled during the transport process.

In addition, such a taping machine (2) when the tape (8) is released for taping, the tape 8 is often generated as shown in Figure 1 (b), so that the frequent stopping factors in the transport flow of the coil In addition, in order to solve such a problem, the worker has to approach the coil carrying line which is automatically progressed, so the risk of safety accident is very high.

The present invention was created in order to solve the above problems, while installing a new pressure taping machine consisting of a pressure roller for pressing the tape directly on the upper surface of the reel and the air cylinder and the iron plate while pressing the coil end portion with the pressure roll. It is an object of the present invention to provide a pressure taping machine which stops on an upper surface of a coil so that the coil can be taped in a state of being fitted to a reel.

The above object of the present invention is a pair of frames each end is connected to the lifting and lowering by an air cylinder fixed to the beam above the coiling coil, facing each other and arranged in parallel; A tape reel rotatably installed at one inner side of the frame; A pressure roll adjacent to the tape reel, spaced toward the other end of the frame, and installed up and down by an air cylinder; A keeping roller and a fix roller, which are installed adjacent to the pressure roll and are arranged to be engaged in the vertical direction so that the tape recommended by the tape reel is passed or pressed securely; A knife set fixed to both sides of the inner surface of the frame in parallel with and adjacent to cut a portion of the tape passing through the kipping roller and the fix roller; An adhesion roller adjacent to the knife set and rotatably mounted up and down; It is achieved by providing a pressure taping machine, comprising a top and bottom fingering is possible to move forward and backward to the lower side of the contact roller, and installed to pull the tape passing through the knife set.

The description of the operation will be described in the order in which the taping operation is performed.

Referring to the drawings and FIG. 6 described above, the operator inserts the filament tape into the tape reel 25 of the pressure taping machine and assembles the rocker 26 to the threaded portion of the tape reel 25 so that the filament tape is fixed horizontally. .

Pulling the first part of the filament tape inserted into the tape reel 25 by hand releases the tape.

At this time, the air motor 20 is adjusted to a state in which the filament tape naturally unwinds.

The first portion of the pulled tape is passed between the fix roller 34 and the keeping roller 33 and pushed to the upper surface of the lower knife 43 of the knife set 40.

At this time, the keeping roller 33 maintains a sufficient distance from the lower fix roller 34 while being lifted by the air cylinders 33a and 33b, and the upper knife 42 is also lifted by the air cylinder 41. The warped state is preferred.

After pushing the filament tape to the upper surface of the lower knife 43, the operator lowers the keeping roller 33 in the pressure taping machine control panel provided separately.

The down keeping roller 33 serves to fix the filament tape.

The following description of the operation is carried out automatically by the programmed logic controller.

When the kiping roller 33 is down, air is injected from the air nozzle 44 at a constant pressure, and the first part of the tape is lifted.

Meanwhile, the upper finger 62 is moved into the knife set 40 to catch the first portion of the filament tape on the upper surface of the lower knife 43 as the air cylinder 60 is advanced by being lifted by the air cylinder 64. Coming in.

When the advance of the air cylinder 60 is completed, the air injected from the air nozzle 44 is cut off and the first portion of the tape is placed on the upper surface of the lower finger 61.

Then, as the upper finger 62 is down, the first part of the filament tape is caught between the lower finger 61 and comes out of the knife set 40 as the air cylinder 60 moves backward.

At this time, it is preferable that the kipping roller 33 is up immediately before the back of the air cylinder 60 is started.

On the other hand, when the air cylinder 60 reverses the upper and lower fingers 62 and 61 holding the filament tape, the air motor 20 gives the back tension so that the filament tape is pulled with a proper force.

It is A of FIG. 6 to wait in the state until the procedure demonstrated above.

The running speed of the iron plate wound on the reel is reduced to 30mpm from 10 to 20 seconds before the winding is completed.

At this time, the air cylinder 10 to down the frame (100a, 100b) of the pressure taping machine and the pressure roll 15 to contact the upper surface (11:40 direction) of the coil.

The air cylinder 10 is controlled by the pressure switch from this time the pressure roll 15 stops the down operation by pressing the upper surface (11:40 direction) of the coil with an appropriate force.

On the other hand, when the air cylinder 10 is down, the air cylinder 70 also stops with about half of the given rod length down.

When the rolled up steel sheet is sheared at the shear, the pressure roll 15 continues to be rolled up until the end of the sheared steel sheet is stopped at the coil upper surface (12:30 direction) as shown in B of FIG. 6. Will be pressed.

Subsequently, when the end of the iron plate of the coil stops on the upper surface of the coil (12:30 direction), the air cylinder 70 is further down by a predetermined distance so that the frames 100a and 100b are as shown in FIG.

When the air cylinder 50 is down, the contact roller 54 closely adheres the filament tape to the coil, and the keeping roller 33 holds the filament tape between the fix roller 34 while down.

The air cylinder 51 ends the taping operation so that the filament tape does not unwind the end of the iron plate from the upper surface (12:30 direction) of the coil while pushing and pulling the body of the air cylinder 50.

At this time, in the knife set 40, the upper knife 42 is up and down, and after cutting the tape, the upper knife 62 returns to its original position, and the upper finger 62 is in contact with the lower finger 61 due to the rod reverse operation of the air cylinder 64. The filament tape was held in between.

When the taping operation by the contact roller 54 is completed, the rods of the air cylinder 10 and the air cylinder 70 simultaneously lift the frames 100a and 100b and return to the state as shown in FIG.

All the above-described operations are performed in one cycle by the programmed P.L.C and are signal-controlled by receiving the information of the coil to be produced.

The pressure taping machine according to the present invention as described above can be used by combining the functions of the conventional pressure roll device and the function of the taping machine, thereby simplifying a complicated device and allowing the coil to be directly taped in a state where the coil is inserted in the reel. Not only can it completely eliminate wrinkles at the end of the iron plate, which caused inconvenience in packing the product, but also solves the tape curl that has occurred in the conventional taping machine. have.
