JPS60118564A - Preventing device for lateral shift of traveling web material - Google Patents

Abstract

PURPOSE:To prevent a traveling web material from shifting laterally by rockably supporting a rocking roller at the central part thereof in the longitudinal direction thereof, and holding both end parts of the roller so as to be rockable by reaction force given from the web material. CONSTITUTION:A rocking roller 6 comprises a left side roller part 8 and a right side roller part 9, both being separated from each other, and the central position of each of the right and left roller parts 8, 9 is supported on a bracket 10 to make the rocking roller rockable horizontally. Both ends of a roller shaft 7 are loosely inserted into long holes 12, 12' of a pair of trackets 11 mounted on both ends of a vertical wall 5c, and moved in the long holes 12, 12' in response to horizontal rocking of both right and left roller parts 8, 9. Accordingly, the rocking roller is rocked in response to lateral shift of a web material , and thereby said shift is corrected, thus preventing the lateral shift from being generated.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is pivotably supported at the center in the longitudinal direction, and both ends thereof are held in elongated holes, so as to be able to resist the reaction force received from the traveling upper plate member. The present invention relates to a traveling pano-eve system misalignment prevention device that can freely swing in response to prevent a traveling web from shifting.

Conventionally, electrocardiographs have been used to diagnose heart abnormalities, for example, and electrocardiographs guide electricity emitted from the heart to outside the body.
Heart diagnosis was performed by drawing a waveform on a moving recording paper with a pen or the like and visually checking the waveform. In this heart diagnosis, a reference line is set in the direction in which the recording paper runs, and judgments are made by visually checking the waveform drawn with a pen around this reference line, so the reference line is running straight. This was an important requirement. If the recording paper is skewed or meandered, the position of the reference line will be distorted, and even if you look at the resulting waveform, it will be difficult to tell whether the recording is due to a cardiac cause or because the recording paper is skewed. The problem arises that it becomes difficult to determine the diagnosis.

Of course, when manufacturing electrocardiographs, efforts are made to eliminate misalignment, but in conventional electrocardiographs, the accuracy of parts such as drive rollers and auxiliary rollers is uneven, and when assembling the electrocardiograph, For reasons such as the unavoidable occurrence of errors in the winding of the recording paper, and the misalignment between the drive roller and the drive roller that runs the recording paper, etc. It was possible to avoid the problem caused by the recording paper being skewed to 11 degrees while it was running.From this point of view, it was important to develop a device to prevent skewing.

In view of the above-mentioned circumstances, the present invention was invented a long time ago in response to the above-mentioned several products. The oscillating rollers 6 are disposed in the middle direction with respect to the traveling direction of the above-mentioned Noeb li p so as to be in pressure contact with each other, and the oscillating rollers 6 are
- The roller 6 is rotatably supported in the medium heat section in the longitudinal direction.
The present invention is made simpler by providing a device for preventing shifting of the traveling web material, which is held in the elongated hole 12° 12' so as to be able to swing freely in response to the reaction force received from the web material p. 14. The running web material has a structure that effectively prevents the buoy from shifting. The main purpose is to obtain an anti-slip device.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of an electrocardiograph to which a device for preventing deviation of a running web according to an embodiment of the present invention is applied. The plate 2 and the back plate 3 which connects the 2'-kichi at the rear form a substantially rectangular shape.
Various devices for running recording paper p, which is a running web material, are built in between the outer plates 2, 2' and the back plate 3. Several curved front cover plates 4 are arranged in front of the outer plates 2, 2', and a stepped inner frame 5 is housed between the outer plates 2, 2', A pen (not shown) for drawing waveforms of electricity emitted from the heart is placed in the upper part 5a of the inner frame. Furthermore, this inner frame 5
A swinging roller 6 for preventing the recording paper p from shifting is attached to the vertical wall 5C hanging down from the lower part 51 of the lower part 51, so that the swinging roller 6 is in pressure contact with the recording paper p running in the longitudinal direction while being in surface contact with the recording paper p. The recording paper p is disposed in a direction perpendicular to the recording paper p.

The structure of this swinging roller 6 will be explained according to FIG. Roller upper middle part: ll+ 7 or 1 conductor 1
Both the left and right roller portions 8 and 9 are connected through this U-ra shaft 7. The medium heat section 7a of the roller shaft 7 is supported by a galley/foot 10 which is separated from the lower part 5b of the inner side of the roller shaft 5 by a vertical wall 5C which is hung by JR. ! The roller shaft 7 is oscillated forcefully in opposite left and right directions in the horizontal direction.The left and right ends of the roller shaft 7 are fitted with a pair of brackets, which are connected to both the groups 11 of the mold 1111.?5C.

The IU (not shown) arranged in the upper part 5,1 of the inner fan 1/-5 draws the electricity led from the heart into a waveform. A drive roller 15 is arranged in parallel with this pen-writing roller 14, and by rotating this drive roller 15, pen-writing is performed on the recording paper from the main roll (not shown) around which the recording paper j] is wound. It is conveyed by rollers 14. An auxiliary roller 16 is provided in parallel with the drive roller 15, and the recording paper p on which the waveform is drawn is conveyed between the auxiliary roller 16 and the drive roller 15, and is transmitted through the storage plate 17 to generate an electrocardiogram.

As explained above, since the present invention has the following configuration, it is possible to prevent the running web material from shifting, which has been difficult in the past.

Furthermore, since it is possible to prevent deviation by simply providing a swinging roller, there are advantages such as being able to efficiently prevent deviation with a simple structure.
