Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coating device for film strips, paper, cloth, composites thereof, processed products, etc. (hereinafter referred to as "Kuepu").

Currently, the coating of Kuep, which is a strip-shaped product, is done by running Kuep between a comma-shaped doctor knife, which has edges at several locations at seven locations on the outer circumferential surface, and a banking roll.
During the passage, a coating film is formed on the surface using the doctor knife. By the way, there is a joint part that is thicker than other parts of the Kuepu to which the resin liquid is applied, but when the joint part of the Kuegu passes through the doctor knife when applying the resin liquid, the joint part of the Kuegu passes through the doctor knife. Trouble may occur such as the part getting caught and the kuep cutting.

Therefore, when the joint part of conventional Kuep approaches the doctor knife, the operator visually observes it and jumps the doctor knife upward to the front and rear parts (approximately 10 m) of the joint part, and when it passes, the doctor knife The knife was restored to its original position and the application of resin liquid was continued. However, although this can prevent problems such as the Kueg being cut, the gap between the doctor knife and the doctor knife that is made to jump upward becomes larger, so the resin liquid The more spillage occurs, the more rapidly the amount of coating is applied to the front and rear parts of the joint, and usually 2 to 5 coats of mold are coated.

For this reason, when performing dry treatment on the front and rear parts of the joint part, which require a large amount of coating, in the dry treatment process, which is a subsequent process, it is necessary to significantly speed up the process, or apply more than a certain amount of the cleaning solution. The workability was extremely poor. Even with such work, there are times when the product is not completely dry, resulting in various inconveniences. Further, when the doctor knife is jumped, there is a problem that the coating amount becomes uneven after the doctor knife jumps IITJ, and the restorability may be deteriorated. Furthermore, if the supply of resin liquid is stopped and the front and rear parts of the joint part of the Kuep are removed, the Kuep will not be processed continuously, and workability will be significantly impaired.

The present invention is based on the above point, has an edge portion of 71 or more on the outer circumferential surface of the roll, and has a front opening that can be used for jumping.
a comma-shaped doctor knife supported by the blade, a joint part detector that detects the joint part of the Kuegu, a speed detector that detects the traveling speed/f of the Kuegu, and a comma-shaped doctor knife that detects the joint part of the Kuegu. The speed corresponding to the distance between the parts is set in advance, and the signal from the joint detector is manually inputted to calculate the output signal of the speed detector, and the speed of the distance between the sections is set as above. By configuring the coating device with a controller that outputs the full signal to operate the doctor knife when the position is reached, it is possible to reduce the coating amount of resin liquid by % without reducing the processing speed of Kuep. He was constantly being abused and abused.

The present invention will be explained below based on the embodiments shown in the drawings.

sb) '2 Drop the doctor knife 11)
One edge portion (2) of the packing roll (2) is previously placed at a lower position to face the outer circumferential surface of the packing roll (4). Then, when the Kuep (6) is run in the direction of the arrow shown in the figure by an appropriate means, the Kuep (6) makes two passes between the edge part 121 of the doctor knife [1) and the banking roll 14) during its travel. , when this passes, the doctor knife 11
) is applied to the surface of the surface to form a Hp Iol' or j. Then, the joint part of the upper part (6) (
7) is detected by the joint part detector 1, and the operation signal 4 is output and sent to the gate 4 and the corresponding gate 135
Encircle 1, then the 1 output from the speed detector Ill barrel
No. 0 is goo) Control +1116 urushi (input to the controller main body battle of 3 yi) via +851 to start the operation, and the feed size of Kuep (6) 1st shift is the setting value of the above setting section - When reaching this point, a signal is output to one or both of the rotating mechanism +121 of the doctor knife 11 and the jumping mechanism (12''4) of the main body of the control device.

That is, first, to describe the case of rotation @ mechanism u21, the shear cylinder 1141 is actuated by the upper signal, its piston rod is moved in and out, and the spindle is thereby moved via the movement rate υal]3) rotates, and the doctor knife (11) is rotated by a predetermined angle in the direction of the arrow shown in the figure at the same speed as or close to the traveling speed of the Kuep (6).

Then, when the edge portion (2) of the doctor knife 11) is positioned at a predetermined position, the arcuate surface +xr is positioned opposite to the packing roll (4). Like this, Kuep (6
) Just before the joint part (7) of ) passes, the doctor knife 111 rotates and faces the arc surface (1r is the banking roll 14), so the doctor knife +13H
As a result, the joint part (7) does not get caught on the edge part (2) of the doctor knife (1) and smoothly moves between the arcuate surface 11r and the banking roll (4). When Kuep (6) passes, the air cylinder (piston rod l1l of I41) immediately expands on its own, and this causes the side knife 711) to have its edge (2) close to the packing roll. (4) Returns to the original position of the lower image normal position. Next, when talking about the Jidingping machine 41221, the output M8. Activate the uniter and rotate the fixed sleeve 1-mu counterclockwise around the cross point, and the edge part (2) of the doctor knife 11) is backing. Facing the roll (4), it is lifted upward in a vertical position, and a gap larger than the thickness of the joint part (7) of the cube (6) is formed, and as a result, the joint part (
7) smoothly passes between the banking roll (4) without being caught by the edge (2) of the doctor knife 11). When Kuep +81 passes in this way, the 1st unit unit eη is activated and the doctor knife (1) returns to its original position before the 1st turn of the joint part (7).Furthermore, the collateral organ main body tBη When a signal is output to both the mechanisms of the and diimping machine di t2Zl, the doctor night y Ill #i each mechanism 1121t2';
is made at the same time, jumps upward while rotating, and returns to its original position as soon as the joint part (7) passes.

Further, when the coating film (1) is formed on the Queg (6), the film thickness is measured using a film thickness measuring device μ field, and at the same time, the film thickness is measured between the doctor knife 11) and the packing roll (4). liJ is measured by l!J interval measurement threshold, and each of these two measuring instruments is Ha instrument (4gJK is continuously input,

The foot price is compared, and if there is a direct difference between the two, the control aJ unit 14
111 J: An operation signal is output to the D actuator, which causes the doctor knife (1) to be fixed at t1i1.
The adjustment arm swings at the cross point of 11t24i.
Move the ship to the specified position in the vertical direction, and then set the above settings and measure 1.
If the straight line corresponds to the straight line, the output from the controller will stop, and the doctor knife 11) will be properly positioned between the packing roll (4) and the packing roll (4). It is maintained at a distance of ljI'fc.

As explained above, the present invention provides /F of the roll outer peripheral surface.
Fr or a comma-shaped doctor knife that has edge parts in several places and is rotatably supported at the same speed as the Kuegu that is running at a distance that is capable of jumping, or at a distance close to this, and detects the joint part of the Kuegu that is running. a joint part detector, a speed detector for detecting the traveling speed of the quag; a setting part in which a value corresponding to the length of the quag between the joint part detector and the edge part of the comma-shaped doctor knife is preset; When the ff1 signal from the joint section detector is input, the calculation of the output signal of the speed detector is started, and when the feed position of the blade reaches the setting of the upper limit setting section, the doctor knife is turned off. Since it consists of a control device consisting of a controller body that outputs a signal for jumping or a predetermined angle movement, there is no need to apply more resin liquid to the joint part of the Kuep. , it is possible to keep the coating time of the tree essence liquid almost constant at all times. Also, depending on the type 4 or properties of the knife, the doctor knife 7 can be rotated or jumped at a predetermined angle, so the joint part can be smoothly moved between rolls without slipping and cutting when pulled by the doctor knife. Moreover, the coating discharge after iJ at the joint part is checked or corrected automatically, and the accumulation rate can be maintained in the same state as in normal operation. In the past, it was necessary to use a special operating method or to process the fish each time it passed through the conventional system, which prevented various troubles and allowed continuous processing without slowing down the processing speed. Processing becomes cIT-enabled, and workability can be greatly improved.
