In this manner, the opening size or the like is measured when the traveller breaks.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a trapeller opening fold measurement device for measuring the opening size and burst pressure of a traveler used in spinning and yarn twisting processes.

BACKGROUND OF THE INVENTION Conventionally, the strength of a traveler was measured by expanding the opening of the traveler and measuring the displacement of the opening when the traveler was damaged.

As an opening jig for opening the traveler, as shown in FIG. There is one that is provided with a scale plate 6 that indicates the opening degree of 1.2.

7 is a traveler 0 Problems to be Solved by the Invention In the above jig, the left and right handle portions 1.
2t - The scale on the scale plate 6 was read while grasping, and the opening amount when the traveler 7 broke was read from the scale plate 6.

However, with the above-mentioned conventional jig, it is very difficult to hold the opening at the moment of breakage, and furthermore, it is difficult to read the opening amount at that time. Furthermore, the traveler's burst pressure could not be measured at all.

Additionally, there was a problem in that there was a considerable amount of error between measurers.

Means for Solving the Problems The present invention has been made in order to eliminate the above-mentioned problems.The fixed mounting member to which one traveler grip part is removably fixed is provided with an operating means, and the other traveler grip part is detachably fixed. A pressure sensor is provided on a slidably arranged movable mounting member to which a portion is removably fixed, and a tip of the operating means is disposed so as to be able to act on the pressure sensor, and the movable mounting member is provided with a differential of a display portion. A measuring section A is configured by arranging an operating rod connected to a transformer.

Further, a display section B is provided with a display function for converting signals from a differential transformer connected to the pressure sensor and the operating rod into electrical signals and displaying the electrical signals.

An object of the present invention is to provide a traveler opening folding degree measuring device configured as described above, which can reliably measure the opening size and breaking pressure at the time of breakage of the traveler.

The working traveler is hooked onto the traveler grip, the handle is expanded by lightly turning the knob of the operating means, and the trapeller is set in the grip. Next, expand the reset holding part of the display, and as soon as the traveler breaks, stop turning the knob and read the display.

By the way, as the operating means is rotated, the operating piece (for example, a steel ball) is pressed against the pressure sensor by the tip thereof, but the movable mounting member resists the pressing force of the tip of the operating means due to the elastic force of the traveler.

Therefore, the pressure sensor detects the elastic force of the trapeller, and its maximum value is detected when the trapella breaks. Note that this value is displayed digitally and the display is held until it is reset. In addition, as described above, the movable mounting member moves against the elastic force of the traveler due to the pressing force of the tip of the operating means, but this movement amount is detected by the differential transformer, and the amount of movement is detected by the differential transformer. The maximum value of the quantity is found. As described above, the burst pressure and opening amount at the time of breakage of the traveler are digitally displayed on the display section by the functions of the seat, pressure sensor, and differential transformer. I will explain based on this.

As shown in FIG. 1, reference numeral 8 denotes an outer cylinder, and an open linear motion ball bearing 9 is fixed to one end of the outer cylinder, and a stop member 10 for the bearing 9 is arranged at the other end. Both ends of the outer cylinder 8 are closed by cover plates 11 and 12 having a hole in the center. Cover plate 11 on the side where bearing 9 is placed
The hole is equipped with a micrometer rad 13 as an operating means.
is positioned and fixed so that its spindle is located inside.

Further, a fixed attachment member 15, which protrudes from the open portion of the bearing 9 and has a traveler grip 14 fixed thereto, is detachably attached to the cover plate 11. Inside the linear motion ball bearing 9, there is a movement guide 17 for the traveler grip 16.
is arranged to be slidable, and a movable attachment member 18 to which a traveler grip 16 is fixed is detachably attached to this movable guide 17. Furthermore, a sensor holder 19 is attached to the movable attachment member 18, in which a pressure sensor 20 such as a ball element or a piezoelectric element is disposed.

Two steel balls 21 are arranged in series between the spindle of the micrometer head 13 and the pressure sensor 20, and the pressure exerted when the micrometer head 13 is operated is transmitted to the pressure sensor 20 by the steel balls 21. It is something. Lid plate 1
2, a hollow body 22 for adjusting the load of the device having a thread carved on the outer periphery is screwed onto the body 22 so as to be movable back and forth. Between the hollow body 22 and the moving guide 17, a spring n for returning the trapeller gripping part 16 is arranged, and when the micrometer head 13 is returned to its original state, the spring n
As a result, the traveler grip portion 16 also returns to its original position. Further, an operating rod 24 is arranged in the hollow body 22, one end of the operating rod 22 is fixed to the moving guide 17, and the other end is connected to a differential transformer (not shown).

Note that the signals output from the pressure sensor and the differential transformer are converted into electrical signals and digitally displayed on the display section.

25 is a nut, which is used to prevent the hollow body 22 from rotating.

Next, an operating method of the present invention will be explained.

First, the display and measurement section A of the display section B is set, and the traveler is hung on the 1-pole tool gripping section 14 and 16. Turn the knob of the micrometer head 13 to lightly fix the traveler. Press the display clear button to reset the display and complete measurement preparation.Next, turn the knob of the micrometer head 13 further and push the legs of the traveler apart.

When the traveler breaks, stop turning and read the display. Then, the knob of the micrometer head 13 is reversed, and the trapeller gripping part 16 is returned to its original position to complete the measurement.

In the above device, the hollow body 22 adjusts the spring pressure of the spring n to set the device load.

Incidentally, in the above embodiment, an IJ-Z is used in the figure as the operating rod for operating the differential transformer, but other connectors may also be used, and there is no connection between the micrometer head and the pressure sensor. Although two steel balls 21 are used, one or more may be used, preferably two or three, and it is also possible to use other working pieces in addition to steel balls.

1. Although a micrometer head was used as the operating means for opening the traveler, an operating lever may also be used.

Effects of the Invention Since the trapeller opening fold measurement device of the present invention has the above configuration, it is possible to simultaneously measure the traveler opening size and fracture pressure at the time of traveler breakage, and moreover, the display section displays the numerical value at the time of breakage. Since it is held and displayed, it can be measured reliably.

In addition, there are no individual differences between people taking measurements, and no special skill is required, making it extremely easy to operate. Furthermore, if there is any unevenness in the hardness of the traveler, only the opening size increases while the pressure remains constant, so it has extremely excellent effects such as being able to easily identify the unevenness in the hardness of the traveler.
