Abstract

PURPOSE:To eliminate dangerous manual operation by providing an actuator for closing a fixed roller upon contact of lug section of sheet against the working roller face. CONSTITUTION:When holding sheet S such as knitted cloth or felt between a pair of nip rollers constituting a cloth guider having displacement detecting means of travelling sheet S, the fixed roller 2 forming the nip roller is first secured while matching to the working roller 3 face with the thickness S of sheet then the actuator 5 for opening/closing the fixed roller 2 is functioned to be rotated to open state. The sheet S is developed in the travelling direction to the winder side and upon contact of the lug section against the working roller 3 face, the actuator 5 is functioned reversely to rotate the fixed roller 2 to the original state matching with the working roller 3 face, thus to hold the sheet S automatically between said rollers 2, 3.

Description

[Detailed description of the invention]

(Industrial Application Field) The present invention relates to a loss guider device for sheets such as knitted fabrics and films, and more particularly to an openable and closable cross guider device that facilitates the holding of sheets between rollers. (Prior Art) Currently, it is well known that sheets of textile fabrics, films, etc. need to be sent out with their running center lines aligned in order to, for example, be used for printing in the next process, such as 9 rolls, and generally a cross guider device is used. A sheet deflection correcting device called ``Seat Deflection Correction Device'' is widely used. In such a conventional cross guider device, a pair of nip rollers, in which a fixed roller and an operating roller are superimposed vertically, are arranged on both sides of the sheet so as to be able to nip it from both the front and back sides, and furthermore, in By adding an inclination, a tensile force is applied to the sheet in the width direction,
For example, when the right-hand actuating roller is released from pressure, the sheet will deviate to the left due to the tensile force.By combining this with an appropriate sheet deviation detection device, the sheet can be accurately brought to the running position. In this case, the nip roller is generally configured to align the sheets with each other.The nip roller in this case is a fixed roller whose handle is directly fixed to the main body frame, and a roller that constantly fixes the sheet using the pressure contact force of an actuator using pneumatic or electric drive. It consists of an actuating roller that presses against the side, and normally, when inserting a sheet of AM fabric, film, etc. between the two rollers, a worker must enter the narrow gap (stages 2 to 12) between the actuating roller and the fixed roller. This is done by manually inserting the sheet by directly holding the edge of the sheet (problem to be solved by the invention). When inserting sheets of knitted fabrics, films, etc., the worker must hold the edges of the sheet and insert the sheet into the narrow gap between the fixing rollers and the rollers, which causes wrinkles in the inserted portion of the sheet. , bending, deformation, etc. easily occur, and in a factory that continuously handles a wide variety of sheets, it significantly impedes work efficiency and is dangerous, including shape correction.Furthermore, another major drawback is that As mentioned above, since there is no other way to insert the sheet into the gap between the rollers other than manually by the operator, it is impossible to save labor through remote control at all. The present invention was made in view of the above-mentioned problems, and its purpose is to provide a cross gaiter device that facilitates accurate insertion of sheets into nip rollers and also enables remote control. It's about doing. (Means for Solving the Problems) The structure of the present invention for achieving the above object will be explained using FIGS. 1 to 3 corresponding to the embodiments. A pair of nip rollers consisting of an operating roller + 3) and a base shaft (71 The sheet (having a thickness of SJ) is fixed to the surface of the actuating roller (3) at all times by the operation of the actuator (5) connected to the base shaft (7). The fixed roller (2) is configured to rotate around the base shaft [71 and can be opened and closed with respect to the operating roller (3I).
The woven fabric is placed between a pair of nip rollers constituting a cross gaiter device having a deflection detection means. A sheet of felt, etc. (When holding the SJ,
Initially fixed rollers forming nip rollers

[2] is fixed to the surface of the actuating roller (3) with a thickness of sheet (S), but the fixed roller (12) is opened by actuating the actuator Ifi+ for opening and closing the fixed roller (2). Rotate to the state of . In this way, after the sheet is stretched out in the running direction to the winding machine side and its ears are brought into contact with the surface of the actuating roller [3], the actuator (5) is then operated in the opposite direction to move the fixed roller [ When the sheet (S) is rotated and fixed again until it matches the original surface of the operating roller 13), the sheet (S) is automatically held between the two rollers 12) and 13). In addition, the actuator for the actuating roller L (l actuator (the actuating circuit of 41 is the fixed roller 12)) the opening/closing actuator 15+
is connected to the operating circuit of the sheet (S), and is input only when the fixed roller (2) is in a fixed state matching the surface of the operating roller [3), and the operating roller 13) moves the sheet (S) to the fixed roller [2+].
Since it comes into pressure contact with the side, the fixed roller (2
) will no longer cause uneven contact with the (S) side of the seat. (Example) Hereinafter, an example suitable for the present invention will be further described based on the drawings. FIGS. 1 and 2 show an example of an openable and closable cross guiter device according to the present invention, with FIG. 1 being a side view and FIG. 2 being a schematic front view thereof. In the figure (Sl is a sheet of knitted fabric, film, etc.

As shown in FIGS. 1 and 2, an arm (lO) extending laterally is fixed to the lower extension part on the J side.
At the head of the [fixed roller 12] there is an actuator (

The actuator (4) for the actuating roller 13 is rotatably attached to the shaft.
, and the fixed roller 12 + opening/closing actuator (
5) are each operated by compressed air in this embodiment, but in this case, the fixed rollers [2] and the actuators for opening and closing (5) are located at predetermined positions so that they can be individually controlled remotely. On the other hand, the actuator [4] for the actuating roller [3] is not inputted when the fixed roller (2) is in the open state; 2) Mechanical pulp (

Furthermore, the operating mechanism for both of the above actuators +41.15) is not particularly limited to the pneumatic method, but other methods are also suitable as long as they can be operated quickly by remote control; for example, an electric method may be used. The fixed roller (2) is connected to an electric circuit for opening and closing the fixed roller (2), which can be operated remotely, through a limit switch, etc. that is set to receive input only when the fixed roller (2+) is closed. This is possible by connecting the operating electric circuit for Ill. Furthermore, fixed rollers + 2) actuators for opening and closing (
As for 61, air cylinders, diaphragms, rotary actuators, etc. are based on compressed air systems.
Further, in the case of an electric type, a motor is preferable, while the actuator (5) for the actuating roller (3) may be of any type as long as it can be linked to the operation of the fixed roller (2) as described above. Further, the open/close cross guider device as a single unit according to the present invention is normally arranged so that the ears of the seat (S) can be held between a pair of opposing sides on both sides of the traveling seat (Sl). In this case, the traveling seat (S) is arranged in a position and posture that can be adapted to grip, release, and press the sheet (S) in all traveling directions, and each Actuator +41.15
) must also be adjusted in advance. Next, the device of the present invention is equipped with a device for detecting deviation of the running sheet (S), which is different from the phototube method used in the conventional cross guider device and the one-air sensor method. It is preferable to connect the fixed roller 12) to the operating circuit to enable automatic control. However, if the conventional deviation detection device with one set of simple levers is used as is in the device of the present invention, the fixed roller + 2
) to open and close the seat (Sl), the lever that is fixed in the detection position (the detection end of LJ is shown in Figure 3 [b)
As shown in FIG. (Connected to 71 etc. and fixed roller (2
) in synchronization with the opening and closing of the lever (Ll wo” seat (S)).
It is preferable that the fixed roller (2) be moved outside the width of the fixed roller (2), and that an operating circuit for opening and closing the fixed roller (2) is connected to the detector to enable automatic control. (Effects of the Invention) The present invention has the above-mentioned configuration, in which the fixed roller is rotated and fixed in an open state, and the sheet is stretched in the running direction to the winding machine side so that the edge portion is aligned with the surface of the operating roller. By closing the fixed rollers again after contact with the sheet and fixing the sheet to the surface of the actuating roller through the sheet, the sheet is held between the rollers. There is no need for the dangerous manual work of inserting the sheets one by one into the narrow gap between the rollers, and the wrinkles, bends, deformations, etc. that would otherwise occur in the vicinity of the insertion area of sheets of textile fabrics, films, etc. This has the effect of significantly improving work efficiency, including the unproductive work steps required for shape correction. Furthermore, since it is now possible to remotely control individual fixed rollers in conjunction with the operating rollers, it is no longer possible for workers to get close to the cross guider, which is located in dangerous places such as high places, unlike in the past. Including work in such dangerous positions, extremely unmodern work methods such as inserting sheets one by one into the gaps between rollers only by the manual labor of workers have been improved all at once. Even if the sheet comes off from the rollers for some reason, there is an advantage that the sheet can be easily gripped normally again by simply opening and closing a pair of fixed rollers of the nip roller in that part while the sheet is running. In addition, if an air actuator is used in place of the actuator for opening and closing the fixed roller, the air cushion can serve as a safety device in the event that the thickness of a sheet of fabric, film, etc. suddenly increases beyond the operating range of the actuating roller. This has the effect of significantly improving efficiency in terms of work processes, including safety management, and further promoting remote control in terms of labor saving, which was not possible with conventional cross guiders. It is.
