[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rolled material marking apparatus for attaching a tape piece to a surface of a rolled material such as an aluminum foil as a mark of a defect such as a scratch or a hole.

[0002]

2. Description of the Related Art When manufacturing a thin aluminum foil, it is difficult to make it thin enough by ordinary rolling. Therefore, two or more rolled materials are repeatedly rolled and rolled to a required thickness. I have. Since the resulting aluminum foil coil is in a state where a plurality of aluminum foils are wound up in an overlapping manner, it is necessary to separate them in another step.
Specifically, the coil is rewound, and one piece of aluminum foil is put on a plurality of other spools while separating a plurality of pieces of aluminum foil.
It is wound up one by one.

[0003] Incidentally, scratches and small holes are apt to occur as defects in the manufacturing process of thin aluminum foil. Since these defects significantly impair the quality of the aluminum foil, the use of the defects and their surroundings is usually avoided. The detection of such a defect is usually performed at the time of separating and winding the aluminum foil described above. When a defect is detected, the surface of the aluminum foil is marked in some way. Defect detection can be performed visually when the winding speed is low, but when the winding speed is high, small defects such as pinholes are easy to overlook,
In general, inspection is performed using an optical surface inspection device or the like. As a result of the inspection, when a defect is detected, a mark is applied to a corresponding portion of the rolled material by marking the surface of the aluminum foil with ink or attaching a tape piece. As a method of attaching the tape piece, insert the tape directly by hand inside the aluminum foil just before winding, or hold the tape at the end of the elongated jig and operate it by hand and insert it In addition, a method is employed in which a tape is rolled in along with rolling of a rolled material.

[0004]

[Problems to be Solved by the Invention] However, all the above-mentioned operations are performed manually, and it is not easy to attach a tape piece to an aluminum foil wound at a high speed in a timely manner. Such problems are likely to occur. Further, when inserting the tape piece, there is a possibility that the hand or the jig may be sandwiched between the aluminum foils, and in any case, there is a problem that the operator must rely on the skill of the worker. This invention has been made in view of the above circumstances, and provides a rolled material marking device capable of attaching a tape piece to an aluminum foil wound at high speed at an appropriate timing and safely. It is.

[0005]

In order to solve the above-mentioned problems, a rolled material marking apparatus according to the present invention sandwiches a tape installation section provided with a long tape for marking and a tape supplied from the tape installation section. A tape feeding section composed of a pair of rolls at least one of which is rotationally driven, a tape cutting section that shears the tape by sandwiching the tape between the pair of cutting blades, and a rolled material from the injection port through the tape injection path through the cut tape section. Gas blowing means to blow off toward the surface, one of the pair of rolls, a projection along the circumferential direction is formed on the outer peripheral surface, and on the outer peripheral surface of the other roll,
Grooves are formed along the circumferential direction corresponding to the protrusions, and between the cutting blades, extend along the blade surface of one cutting blade toward the blade surface of the other cutting blade. A cutting blade guide portion that is in contact with and contacts the lever surface is provided.

As a rolled material to which the present invention is applied, an aluminum foil can be mentioned first. However, the invention of the present application is not limited to this, and can be applied to other rolled materials made of metal. In addition, the mark by the tape piece is one of the objects to be used as a mark of the defect of the rolled material, but the invention of the present application is not limited thereto, and may be used for other information display purposes. . For this long tape, usually a tape coil wound in a coil shape is used, but the present invention is not limited to this.
For example, a folding tape can be used. Also,
Preferably, the tape cutting section is detachably attached to the marking device.

[0007]

According to the present invention, the long tape for attachment is provided in the tape setting section, and the end of the tape is fed toward the tape cutting section by the tape feeding section. The protrusions and grooves are formed on the outer peripheral surface of the pair of rolls of the tape feed unit, so the tape sent by pressing both is formed with folds along the lengthwise direction, preventing tape deformation Is done. In the tape cutting section, one of the cutting blades is in contact with the cutting blade guide, and the cutting blades are always positioned with an appropriate clearance. Therefore, at the cutting portion, the tape end portion is appropriately cut at an appropriate size to obtain a desired tape section. When the tape needs to be adhered in this state (for example, detection of a pinhole), gas is injected from the gas injection unit, and the tape section that has been waiting is blown off from the injection port to the rolled material through the gas injection path, and the surface of the rolled material is removed. Adheres to At this time, the tape section is formed with a fold at the tape feeding portion and the rigidity is increased, and the deformation such as curl is prevented and the flat shape is maintained, so that the tape ejection path and the ejection port do not catch on the tape ejection path. It moves smoothly and is ejected. Thereafter, in the tape feeding section, the tape is continuously fed toward the cutting section and cut, and when the tape needs to be attached, the operation of blowing off the tape piece is repeated in the same manner as described above.

On the other hand, the upper pressing roll 17 has a shaft portion 17a.
The shaft 17a is fitted from above into a U-shaped groove provided in the upper part of the side wall of the apparatus main body 1. A coil spring 23 is disposed in a compressed state in a gap between the shaft portion 17a and a roll pressing plate 22 screwed to the upper surface of the apparatus main body 1 above the shaft portion 17a. It is energizing. At the center of the surface of the upper pressing roll 17, a ridge 17 c is formed along the circumferential direction, and corresponds to the groove of the lower driving roll 16.

An accommodation recess 25 for accommodating a cutting section described later is formed in the apparatus main body 1 in front of these rolls, and the accommodation recess 25 has a shape adapted to the outer shape of the cutting section. The cutting portion includes a plate-shaped lower blade block 26, a cutting portion main block 27, an upper blade 28, and a cutting portion slave block 2.
9 and an upper blade driving air cylinder 30. A lower fixed blade 26a is formed on the upper portion of the lower blade block 26. On both sides of the lower fixed blade 26a, a cutting blade guide portion 26b flush with the blade surface of the lower fixed blade 26a extends upward. I have. In this embodiment, the cutting blade guide 26b is
Although it is formed integrally with the cutting blade, the present invention is not limited to this, and it is possible to use another member. Although the blade surface of the lower fixed blade 26a is flush with the blade surface, it is also possible to change the position of the guide portion so that a predetermined clearance is obtained between the upper and lower blades.

The lower blade block 26 is provided in the tape through hole 2.
It is attached to the cutting section main block 27 in which 7a is formed with a bolt 32a and a nut 32b via a disc spring 31.

Therefore, by adjusting the tightening force of the bolt 32a and the nut 32b, the above pressing force can be appropriately adjusted. By applying the pressing force between the two blades in this manner, the cutting blade and the cutting blade guide can be reliably and stably contacted. Further, the upper blade 28 is fixed to an operating rod 30a of an upper blade driving air cylinder 30 with a screw member 30b. The upper blade driving air cylinder 30 is fixed to the upper surfaces of the cutting blade main block 27 and the cutting portion sub-block 29. Note that a return spring (not shown) is built in the air cylinder 30, and after the operation is stopped, the operating rod 30a and the upper blade 28 return to their initial positions by springback. The cutting section constituted by these members can be easily attached to or detached from the apparatus main body, and it is also possible to replace only the lower blade or the upper blade. Is easy, and the repair cost can be reduced. Further, the upper and lower blades intersect with an appropriate clearance and pressing force at the time of cutting, so that the life of the cutting blade is significantly improved.

Further, in front of the cutting section, the distal end of the apparatus main body 1 is elongated and allocated to the lower guide block 35, and the upper surface of the lower guide block 35 The upper guide block 36 is arranged and fixed so as to have a predetermined gap. A tape ejection path 37 is formed by the space between the upper and lower guide blocks 35 and 36. The tape ejection path 37 is opened at the front surface and a tape section ejection port 38 is formed. On the rear end side of the upper guide block 36, the tape ejection path 37 is inclined forward.
An air injection path 39 is formed at the base end of the air injection path 39. The air injection path 39 is connected to an air injection device (not shown) provided outside the apparatus main body 1.

Next, the operation of the marking device will be described. The winding shaft 40 is fixed to a winding device (not shown), and the aluminum foil 41 is wound on the winding shaft 40 to form an aluminum foil coil. The coil being wound is pressed by a touch roll 42, and the touch roll 42 is attached to a winding device so as to slide in accordance with the thickening of the coil. The mounting shaft 3 for fixing the marking device is mounted on the winding device 43 so as to interlock with the slide of the touch roll 42 described above. The marking device is fitted to the mounting shaft 3 so that the tape ejection port 38 faces the winding portion of the aluminum foil,
Tighten the keyed screw 4 to fix it.

When the aluminum foil 41 is wound, an inspection light is irradiated from one side of the aluminum foil 41 being wound, and the inspection light is received on the other side to inspect the presence or absence of a pinhole. The inspection result in the light receiving section is input as an electric signal to a control device (not shown) for controlling the marking device. In the marking device, the leading end of the tape 5 c is pulled out from the tape coil 5, hung on the guide roll 13, passed between the upper and lower guide plates 14 and 15, and disposed between the drive roll 16 and the pressing roll 17. In the guide roll 13, the washer 13c acts as a ridge, improving the straightness of the tape and preventing meandering. It is also effective in elongating tape wrinkles. The number of washers, that is, the number of ridges is arbitrary, and the ridges may be discontinuous.

Next, the motor 21 is operated to rotate the drive roll 16 clockwise (in FIG. 1) to
The end of c is sent to a predetermined length toward the tape cutting section.
The feeding length of the tape 5c can be adjusted by the rotation time of the motor, and the rotation time of the motor is controlled by a timer (not shown). Therefore, the feeding length of the tape can be changed by adjusting the set time of the timer. A thin groove 16 b is formed on the outer surface of the driving roll 16, and a ridge 1 is formed on the outer surface of the pressing roll 17.
Since the tape 7c is formed, folds are continuously formed in the tape 5c along the lengthwise direction at the same time as the tape is fed, so that the rigidity of the tape 5c is increased, and the tape 5c is reliably cut without twisting or displacement. Sent to the department. In addition, narrow groove,
The number of ridges can be varied and can be discontinuous.

In the tape cutting section, the cutting blade driving air cylinder 30 is operated to lower the upper blade 28. Upper blade 28
Descends along the cutting blade guide portion 26b, and finally crosses the lower fixed blade 26a and shears the tape 5c located between the both blades. The cut tape section 5 d is located in the tape ejection path 37, and a small breeze is blown from the air ejection path 39 to prevent the tape section 5 d from sticking to the inner wall of the tape ejection path 37, and the tape ejection path 37. Let me wait inside. In this state, the pinhole is inspected while the aluminum foil 41 is wound. If a pinhole is detected during the winding operation, the detection result is transmitted to the control device, and instructs the marking device to jet the tape. Specifically, the air injection device is controlled to inject air vigorously from the air injection path 39 (3 to 4 kg / cm ² ), and the tape injection path 37 is controlled.
The tape section 5d that is waiting at the above is blown off from the injection port 38 toward the aluminum foil 41 being wound. The tape section 5 d adheres to the surface of the aluminum foil 41 so as to be wound between the aluminum foils.

Further, in the marking device, a tape section to be used next time is made to stand by in a tape ejection path.
Activate the tape feeder and tape cutter. Then, when a pinhole is further detected in the aluminum foil being wound, the tape section in the waiting state is blown off toward the aluminum foil and adhered in the same manner as described above, and then the next tape section is made to stand by. By repeating this operation, the tape section can be attached to the aluminum foil in a timely and safe manner. In addition,
Even when pinholes are continuously detected at relatively short distances, it is desirable that the feeding and cutting of the tape be completed in a time as short as possible so that the tape pieces can be attached in time. For example, responsiveness can be improved by adopting a rack and pinion driving method instead of a motor, and this demand can be met. Moreover, according to the rack and pinion type, there is an advantage that the installation space for the motor is not required.
