Abstract

PURPOSE:To permit the transfer direction to be varied simply and at a low cost without injuring the band-shaped continuous material such as paper by varying the direction of transfer for the continuous band-shaped material such as paper etc. which are introduced from an inlet roller, by means of a three-dimensional tilted turn-bar which is tilted both in the same plane as that of the inlet roller and in the plane vertical to said plane. CONSTITUTION:The continuous band-shaped material 2 such as paper etc. is introduced from an inlet roller 3 and taken-up onto a turn-bar 6 which is three- dimensionally tilted to an inlet roller 3, and forms a flat plane. In said flat plane, the angle theta1 formed by the turn-bar 6 against the inlet roller 3 is set, for example, within the range of 45-90 deg.. Then, the continuous band-shaped material 2 is taken-up onto the turn-bar 6 and an outlet roller 4', forming a flat surface, then varied in the direction of its advance by the turn-bar 6, and carried- out from the outlet roller 4'. In this case, the angle theta2 formed by the both 6 and 4' described in the above is set equal to the above described angle theta1, and the angle theta3 formed by the turn-bar 6 and the side edge of the paper 2 is set for example, to 90 deg.-theta1.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for changing the direction of a flexible continuous strip such as paper, film, cloth, etc. in the transport direction.

Conventionally, patterners have generally been used as a means for changing the direction of continuous strips in the transport direction. A conventional means for changing the orientation of a strip in the transport direction using a turnper will be explained with reference to FIG. 1.2.3. The strip of paper introduced at the entrance roller 3 is
After changing the conveying direction by 90 degrees using the turn bar 1, which is on the same plane as that and inclined at 45 degrees, the paper 21 is placed on the lower side of the back of the turn bar 1, that is, the paper 21 from the turn bar 1 is received as it is being transferred horizontally. , the paper 2 is received by the exit roller 4, and the paper 2 is sent out after changing its direction with respect to the transport direction. Also, since the location of the exit roller 4 is remote from the paper transport path to the device, the path of the output paper is generally brought closer to the device through yet another row 25.

In this method, 1) it is difficult to manually thread the paper in the first place; 2) Since the paper 2 is wrapped approximately 180 degrees around the turn bar l inclined at 45 degrees to cause a sudden direction change, the friction between the paper 2 and the turn bar 1 increases and the paper 2 is damaged. 3) Since the exit roller 4 is provided at right angles to the entrance roller 3, the width of the device becomes large. 4) Outlet row 24't-population roller 3
If the paper 2 is to be brought towards the center of the device in order to be more spaced apart and at right angles, another roller 5 must be provided. There are drawbacks such as.

SUMMARY OF THE INVENTION An object of the present invention is to provide a turn bar device that eliminates the drawbacks of the prior art described above, can be manufactured compactly and at low cost, and can change its orientation with respect to the conveying direction without damaging the strip.

The turn bar device according to the present invention that changes the orientation of a strip with respect to the transport direction uses a three-dimensional inclined turn bar that tilts the RBFT continuous strip introduced by an inlet roller in the same plane as the roller and in a plane perpendicular to the roller. This is a three-dimensional tilt patterner device in which changing direction is a 1-* sign.

In a preferred embodiment of the turn bar device according to the present invention,
An inlet roller and an outlet roller are arranged at right angles to each other on parallel planes having an interval in the vertical direction, and a straight line between the two rollers connects one end of the inlet roller and the opposite side of the outlet roller to the inlet roller. A turn bar is arranged parallel to the inlet roller so that the continuous strip is tilted three-dimensionally from the inlet roller to the outlet roller and passed through the outlet roller.

In another preferred embodiment of the turn bar device according to the present invention, the strip is longitudinally cut by the inlet roller into a plurality of parallel strips, and each of the strips is cut into a plurality of parallel strips. The direction of the transfer is changed by the turn bar, and furthermore,
('nt--pass through the exit roller and overlap.

Hereinafter, the apparatus of the present invention will be explained based on FIGS. 4 to 7 of the drawings of the embodiment.

The continuous strip 2 introduced by the entrance roller 3 is wound around the entrance row 23 and the three-dimensionally inclined turner 6 to form a flat surface. The angle formed by the turn bar with respect to the inlet roller 3 within the flat plane is θl, which is greater than 45 degrees and smaller than 90 degrees. If θ1 is small, there is a risk of straining the paper, and if it is too large, the device will become unnecessarily large. θ1 is preferably 50 to 70 degrees. Furthermore, the continuous strip 2 has a turn bar 6 that is inclined three-dimensionally.
is wound around the exit roller 4' to form a flat surface, and within this flat surface, the angle between the turn bar 6 and the exit roller 4' is defined as θl.

Incidentally, since the entrance roller 3 and the exit roller 4' exist in a horizontal plane, θl and 01 are at the same angle, and the continuous moving body 2 introduced by the artificial roller 3 is controlled in its traveling direction by the three-dimensionally inclined turn bar 6. is changed and sent out from the exit roller 4'. As shown in the figure, it is desirable to have both ends of the turn bar 6 close to the intrusion roller 3 and the exit roller 24' to make the device smaller. The angle θ-=90° between the turn bar 6 and the side edge of the paper 2 is -θ.

The paper 2 starts turning from point A where it starts contacting the three-dimensional inclined turn bar 6, and turns at point A2 at the same phase in the traveling direction of the paper on the opposite side.
After the point passes through the turn bar 6, it reaches point B' and completes the turn for the entire paper width.At this time, point A, where the turn first started, is at point B.

This turn bar is designed so that the distances from the paper edge points A and A' to points B and B' are the same, that is, A-B=A
It must be tilted in three dimensions so that '~B'. If this distance is different, the paper may wrinkle or be cut.

Volume G Tomoe Now here, the contact line of the paper of the entrance loaf is the 3rd turn bar 6
The width of the paper is assumed to be d, which is equal to the length of the roller, and the exit roller is located at a distance of d from the origin on the X-axis. (d, o,
o), the inlet roller lies at a point (otd, -e) from the point (o, o, ri), and the three-dimensional turn bar 6II'i point (d, o ,o
) and the point (Ob, Ai), which indicates a three-dimensional slope.

Further, as shown in FIG. 8, the strip 2 is cut vertically by the cutter 7 at the entrance row 23 into two parallel strips, and each of these strips is divided into two mutually parallel strips. The three-dimensional inclined turn bars 6A and 6B change the direction of conveyance, and furthermore, the strips can be stacked and fed out through the exit rollers 4A and 4B' with the direction changed.

Of course, in the three-dimensionally inclined turn bar of the present invention, the turn bar is also provided with air blowing equipment in order to reduce friction with the strip.

By providing the three-dimensional inclined turn bar as detailed above, the following effects can be achieved.

il+ Since the angle at which the paper is fed to the turner is small and the paper is turned smoothly, the paper is less likely to be damaged and the number of defective products can be reduced.

f2+ The device can be manufactured at low cost without increasing the width of the device.

(3) It is easy to thread the paper when it is first obtained. (4) The rollers used to pull the turned paper toward the center with the conventional device require construction costs.
