Abstract

PURPOSE:To enable winding of long strip sheet without abnormality or wrinkles by comparing signals of sheet winding periphery diameter converted from a winding roller's rpm signals with guide roller position signals, thereby controlling the gap between the winding periphery and the guide roller to be constant. CONSTITUTION:Periphery diameter D of long strip sheet S increases as winding process goes on and is always detected with a signal processor 18 to be compared with detected position signal of a guide roller 11 obtained from a rotary potentiometer 16, which is arithmetically processed and outputted as a control signal to a driving device 19 so that the roller 11 is pulled apart according to increase in the periphery diameter D from the winding roller 10 for maintaining the gap between the roller 11 and the periphery of sheet S wound around the roller 10 to a preset value A. Using this signal, a driving device 19 activates a hydraulic cylinder 14 to retract a piston rod 14a until the gap between the roller 11 and the periphery of sheet wound around the roller 10 becomes the preset value A. Thus, long strip sheet can be wound without abnormality, wrinkles or air being trapped.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a winding device for a continuous long sheet of paper, film, cloth, web, etc. The present invention relates to a winding device of the type that winds the winding around the winding roller via a guide roller disposed close to the winding roller.

Conventionally, in production processing lines where continuous long sheets of paper, film, cloth, web, etc. are subjected to continuous processing such as coating and printing, the above-mentioned A long sheet is wound into a roll.

The winding operation as described above is performed using a winding device as shown in FIG.

The winding device (1) includes a winding roller (
2) is arranged parallel to the take-up roller (2) and at a predetermined distance A, and the long sheet (S) is placed between the take-up roller (2) and the long sheet (S). ) and a guide roller (3) that crosses the winding roller (2).
As the outer circumferential diameter of the long sheet (S) wound around the winding roller (S) increases, the guide roller (3) is changed between the long sheet (S) wound around the winding roller (2) and the guide roller (3). The winding roller (2) is moved in a direction away from the winding roller (2) so that the predetermined distance A is maintained between the opposing outer peripheral surfaces of the winding roller (2). That is, by moving the guide roller (3) so as to maintain the predetermined distance A, a constant tension is always applied across the width of the long sheet (S) being wound up by the take-up roller (2). This prevents wrinkles, air intrusion, and uneven winding.

However, in the above-mentioned conventional continuous sheet winding device, the outer circumferential diameter of the long sheet (S) wound around the winding roller (2) is mechanically measured, e.g. , is detected by bringing a roller-shaped contact into contact with the outer periphery of the long sheet (S), while the position of the guide roller (3) is detected by a phototube, and the long sheet (S) is moved to the take-up roller (2). The movement of the guide roller (3) was controlled while maintaining the predetermined distance A according to the amount of winding of S). However, this would complicate the entire winding device, and It may become a hindrance when replacing the take-up roller (2) that took up the long sheet (S) with a new take-up roller (2), or the position detection accuracy of the guide roller (3) by the phototube may be affected. Low guide roller (3
) is moved intermittently, and furthermore, the photoelectric tube has problems in that its operation becomes unstable due to vibrations of the winding device itself.

The present invention is a winding device for winding a continuous long sheet of paper, film, cloth, web, etc. onto a winding roller via a guide roller, the winding device moving the guide roller in a diametrical direction. A long sheet wound on the take-up roller receives a signal of the rotation speed of the take-up roller obtained from a moving means, a position sensor that detects the position of the guide roller, and a control device for the driving morph of the take-up roller. A signal processing device compares and processes this signal with a position signal of the guide roller from the position sensor, and a control signal output from the signal processing device causes the guide roller to wind. a drive device that operates the moving means to maintain a constant distance from the outer peripheral surface of the long sheet wound around the take-up roller; and a shift setting device that sets and inputs the constant distance to the signal processing device. This is a winding device for continuous long sheets.

In addition, the continuous long sheet winding device according to the present invention uses a signal processing device to transmit a signal of the rotation speed of the winding roller obtained from the control device of the drive motor of the winding roller to the winding roller. After converting into a signal of the outer circumference diameter of the long sheet, this signal is compared and arithmetic processed with the position signal of the guide roller obtained from the position sensor, and the control signal output from this signal processing device to the drive device is used to perform the above-mentioned The moving means is operated so that the guide roller maintains a constant distance from the outer peripheral surface of the long sheet wound around the winding roller, and in this state the long sheet is wound around the winding roller.

A rod (32) supporting the cutter (12) is slidably fitted in the support bracket (31) in the axial direction, and the cutter (12) is positioned between the plate member (30) and the cutter (12). A plunger actuator (not shown) disposed in the plate member (30) allows the plate member (30) to move horizontally while remaining parallel to the plate member (30).

The aforementioned hydraulic cylinder (14) and air cylinder (33) are arranged on the outer side of the fixed frame (21). The piston rod (1) of the hydraulic cylinder (14)

The operating procedure of the continuous long sheet winding device according to the present invention will be explained below. In the initial state, the piston rod (14a) of the hydraulic cylinder (14) and the piston rod (33a) of the air cylinder (33) are both in an extended state, so that the take-up roller (10) and the guide The rollers (1)) are in contact with each other. Furthermore, since the plunger actuator (not shown) is in the retracted state, the cutter (12) has retreated to the position shown by the two-dot chain line in the figure.

"First, when the shift setting device (20) sets the distance between the opposing outer peripheral surfaces of the take-up roller (10) and the guide roller (1) to a predetermined value A, the signal processing device (18) A control signal is output to the drive device (19) according to the set value A. This drive device (19) outputs a control signal to the piston rod (14a) of the hydraulic cylinder (14) according to the control signal.
The guide roller (1) is moved away from the take-up roller (10). The position of the guide roller (1)) is located on the movable frame (15) together with the guide roller (1)).
Binion gear (27) and fixed frame (21)
) is detected by the rotary potentiometer (16) rotating in synchronization with the pinion gear (27) and input to the signal processing device (18). The signal processing device (18) is connected to the guide roller (1
)) position detection signal and shift setting device (20) setting value A
Until the position of the guide roller (1)) from the take-up roller (10) reaches the set value A, that is, the position of the guide roller (1)) and the take-up roller (10) is compared and calculated. A control signal is output toward the drive value R (19) until the distance between the opposing outer peripheral surfaces reaches the set value A, and the hydraulic cylinder (
The piston rod (14a) of 14) is retracted to the protrusion length B.

Next, cross the long sheet (S) from above the guide roller (1) to below the take-up roller (10), and place the tip of the long sheet (S) on the take-up roller (lO). wrapping,
After that, the motor (M) is started and the take-up roller (10)
is rotated clockwise to wind up the long sheet (S).

During the winding operation, the outer circumferential diameter of the long sheet (S) wound around the winding roller (10) is such that the long sheet (S) is moved at a constant speed V in the longitudinal direction. ), it is determined by detecting the rotational speed N of the take-up roller (10). In other words, the outer diameter is (
Since there is a proportional relationship between speed (speed)/(rotation speed N), the signal processing device (18) calculates the rotation speed N of the take-up roller (10) of the motor (M) obtained from the control device (19). After detection from the rotational speed signal, calculation processing is performed using the above-mentioned proportional relationship, and the signal is converted into a signal representing the outer circumference diameter. Therefore,
As described above, the outer circumferential diameter of the long sheet (S), which increases with the above-mentioned end-of-life operation, is always controlled by the signal processing device (18).
is detected by the signal processing device (18).
The outer circumferential diameter of the long sheet (S) is determined by comparing and calculating the outer circumferential diameter detection signal and the guide roller (1) position detection signal obtained from the rotary potentiometer (16). The guide roller (1)) is separated from the take-up roller (10) in accordance with the increase in A control signal for maintaining the distance between the outer circumferential surfaces at the set value A is output to the drive device (19). Then, this control signal causes the drive device (19) to operate the hydraulic cylinder (14).
), then operate the guide roller (1)) and take-up roller (1).
The piston rod (14a) is retracted until the distance between the outer circumferential surface of the long sheet (S) wound up on the piston rod (14a) reaches the set value A.

As described above, the distance between the long sheet (S) wound on the take-up roller (10) and the guide roller (1) is always kept constant to prevent wrinkles, irregular winding, etc. After winding up a specified amount of long sheet (s), stop the motor (M), remove the winding roller (10) from the winding device, and wind up a new winding roller (10'). Attach to the device (
(state shown in FIG. 4).

From this state, the plunger actuator (not shown) causes the cutter (12) to protrude from the position indicated by the two-dot chain line in Fig. 4 to the position indicated by the solid line, and the hydraulic cylinder (1
4) to extend the piston rod (14a) to the protruding length B.
When the guide roller (step 1) and cutter (
12) moves to the position indicated by the one-dot chain line. In this state, the distance between the opposing outer peripheral surfaces of the new take-up roller (10') and the guide roller (1) is the set value A.

Next, when the air cylinder (33) is operated to cause the piston rod (33a) to protrude, this piston rod (33a) is activated.
The protruding operation in a) moves the entire hydraulic cylinder (14) forward via the swing arm (35), so the guide roller (1)) and cutter (12) move from the position indicated by the dashed line in the figure to the solid line. The guide roller (1)) is brought into contact with the new take-up roller (10') with the long sheet (S) interposed therebetween, while the cutter (12)
cuts the long sheet (S) between the new take-up roller (10') and the take-up roller (10) that has wound up a specified amount of the long sheet (S).

The winding roller (
10) is transferred to the next process or a predetermined storage, and when the motor (M) is started and the take-up roller (10°) is rotated, the long sheet (S) cut by the cutter (12) The end of the winding roller (10
It moves along the outer circumferential surface of the take-up roller (10') as the sheet rotates, and is caught between the take-up roller (10°) and the long sheet (S) at the point when it has made approximately one turn. The long sheet (S) is wound around a take-up roller (10°). At the same time, the plunge actuator (not shown) is operated to retract the cutter (12) to its initial state, and
When the piston rod (33a) of the air cylinder (33) is retracted to the initial state, the hydraulic cylinder (14)
Since the piston rod (14a) of ) protrudes by the protrusion length B as described above, the long sheet (S) wound around the take-up roller (10'') and the opposing outer circumferential surface of the guide roller (1)) The distance between them is the set value A.

Thereafter, the long sheet (S) is sequentially wound up on the winding roller (10') according to the above-mentioned procedure.

In the above description, the guide roller (1) is controlled so as to be always a predetermined distance away from the outer circumferential surface of the long sheet (S) wound up by the take-up roller (10), but the present invention In the device, when the predetermined distance is set to O using the shift setting device (20), the guide roller (1)) is moved to the outer peripheral surface of the long sheet (S) being wound up by the take-up roller (10). It is also possible to wind up a long sheet (S) in a state where it is always in contact with the sheet.

As explained above, the continuous long sheet winding device according to the present invention uses a signal processing device to control the rotational speed of the winding roller obtained from the control device for the drive motor of the winding roller. After converting the signal into a signal representing the outer diameter of the long sheet wound on the take-up roller, this signal is compared and processed with the position signal of the guide roller obtained from the position sensor, and this signal processing device outputs the signal to the drive device. actuating the moving means so that the guide roller maintains a constant distance from the outer peripheral surface of the long sheet wound on the winding roller according to a control signal output from the winding roller;
Since the long sheet is wound onto the take-up reel in this state, the above constant interval can be maintained accurately regardless of disturbances such as vibration of the winding device, and the long sheet is wound onto the take-up roller. It is possible to wind the sheet without any disturbance, wrinkles, or air, and since the outer diameter of the long sheet is electrically detected as described above, the winding roller that has wound up the specified amount of the long sheet can be easily used. When taking out the long sheet from the winding device, unlike conventional winding devices, the mechanism for detecting the outer diameter of the long sheet does not get in the way, and the workability is extremely high.
