Description

[Detailed explanation of the invention] (Industrial application field) This invention can be used in mass retailers, home centers, etc.
This invention relates to a length measuring device used when cutting and selling long rope-like bodies such as electric wires, hoses, and strings into appropriate lengths.

(Conventional technology) Conventionally, this type of dedicated length measuring instrument did not exist.
The elongated object can be measured by sequentially applying the elongated object to the elongated object using a straight elongated object made of bamboo or the like, or by sandwiching the elongated object between a measuring roller and an auxiliary roller that are always kept in elastic contact with each other by a spring. The length measurement roller was rotated by pulling the length.

(Problem to be solved by the invention) However, the conventional method of measuring the length of a long object by sequentially applying a straight length to the long object is time-consuming and troublesome; There was a problem with not being able to measure accurately. In addition, in the latter method of sandwiching the elongated object between the length measuring roller and the auxiliary roller, the rollers are maintained in elastic contact, so in order to sandwich the elongated object between the rollers, a spring is required. It is troublesome as it is necessary to attach the elongated body while pushing the space between the rollers apart against the force, and since the spring force and the outer diameter of the elongated body are not linked, the outer diameter of the elongated body is Depending on the size of the long body, slips may occur between the rollers and the long body, excessive clamping force may be applied to the long body, damaging the long body, and the size of the outside diameter of the long body may cause slippage. This resulted in the problem of large measurement errors.

In the length measuring instrument of the present invention, one end of the upper and lower scissors is rotatably pivoted, and the other end is an open free end, and the open free end is moved in the opening direction between the upper and lower scissors. A biasing spring is interposed, a length measuring roller and an auxiliary roller are rotatably attached to opposing positions of the open free end, and a guide for guiding the object to be measured between the rollers is attached to at least one of the scissors. The upper scissors are provided at one open free end, and include a measuring means for measuring the amount of movement of the object sandwiched between the rollers through the rotation of the length measuring roller, and a display section for displaying the measured value. A reset section is provided.

(Function) According to the present invention, since the upper and lower scissors a and b are rotatably pivoted at their ends, the length measuring device is rotatably attached to the open free ends of the scissors a and b. The space between the secondary roller 1 and the auxiliary roller 2 can be opened and closed. By guiding the measured object d to the guide 3, sandwiching it between the rollers 1 and 2, and pulling the measured object d, the measured object d is pulled between the rollers 1 and 2.
, and one of the length measuring rollers 1 is moved accordingly.
The amount of movement of the object d is measured by the measuring means through the rotation of the object d, and the length of the object d is measured. Furthermore, the length measuring device of the present invention has a length measuring roller and an auxiliary roller attached to opposite positions of the open free end, and a spring interposed between the upper and lower scissors.
Since the rollers are biased in the open direction and the space between the rollers is maintained in an open state, the object to be measured can be easily mounted between the rollers. By manually applying a pressing force according to the outer diameter of the object to the upper and lower scissors, the object to be measured can be clamped between the rollers with an appropriate clamping force, making it easy to operate. Further, since excessive clamping force is not applied to the object to be measured, the object to be measured is not damaged, and measurement errors are small regardless of the size of the outer diameter of the object to be measured.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

In the drawing, a indicates an upper scissor, b indicates a lower scissor, the scissors a and b are arranged one above the other, and a shaft c is inserted into one end of the scissors a and b, and the scissors rotate around the shaft c. movably pivoted, scissors a,
The open free end of b can be opened and closed. Further, a spring e is interposed between the scissors a and b, and the elasticity of the spring e urges the free ends of the scissors a and b in the opening direction.

Reference numeral 1 indicates a length measuring roller, and reference numeral 2 indicates an auxiliary roller, which are rotatably attached to opposite positions of the open free ends of the upper scissors a and the lower scissors b, respectively. It is designed so that it can be pinched.

The length measuring roller 1 is rotatably provided on an axis a3 provided in the length direction of the upper scissors a, and is supported by a support a1 arranged parallel to the open free end of the upper scissors a, as shown in FIG. , a2, which is rotatably attached to the shaft a3. The auxiliary roller 2 may be rotatably provided on a shaft b2 provided in the longitudinal direction via a support portion b1 inside the lower scissors b having a U-shaped cross section. Upper scissors a between length measuring roller 1 and auxiliary roller 2
and can be opened and closed as the free end of the lower scissors b is opened and closed.

Note that when the object to be measured d moves between the roller for length measurement 1 and the auxiliary roller 2, the surface of the roller for length measurement 1 is made of rubber in order to directly transmit the amount of movement of the object to be measured d to the rotation of the roller for length measurement 1. A covering material is provided to increase friction, or the outer peripheral surface is made uneven.

A guide 3 is provided at the open free end of at least one of the scissors a or b to allow the object to be measured d to move between the length measuring roller 1 and the auxiliary roller 2. In the drawing, an example of the guide 3 is shown in which a hole is formed in a plate-like member provided upright on one side of the lower scissors b. By pressing the object d against the hole edge of the guide 3 and bending it, a mark can be placed on the object d, which is convenient when cutting the object d to a desired length.

Reference numeral 4 denotes a display section, on which a value measured by a measuring means of the rotation of the length measuring roller 1 as the object to be measured d moves is digitally displayed, and a reset section 5
It is set to return to 0. The display section 4 and the reset section 5 are provided at positions where they can be easily seen from above the upper scissors a and can be easily operated with one hand, and are usually provided on the upper surface of the upper scissors a.

The object to be measured d is measured based on the rotation of the length measuring roller 1.
As a measuring means for displaying the amount of movement of A gear 6 is provided on the top, and an interlocking gear 7 is provided to mesh with the gear 6.
As the axis of the interlocking gear 7 rotates due to the rotation of the length measuring roller 1, a number is counted on the display section 4 via a rotary digital counter mechanism. Alternatively, the length measuring roller 1 or the shaft a3 may be directly connected to a rotary digital counter mechanism, and a decimal ring is used to display these counters.

In addition, as a measuring means, in FIG.
is fixed to the shaft a3, and the disc body 8 has through holes 81 arranged at regular intervals on the same circumference. The through hole 81 of the disc body 8 has a rotation amount of the length measuring roller 1,
That is, the sensor 9, which is provided to detect the amount of movement of the object to be measured d between the rollers 1 and 2 and is equipped with a light emitter and a light receiver, detects the amount of light that passes through the sensor 9 as the disc body 8 rotates. Hole 81 is what is detected. The result detected by the sensor 9 is sent as a signal to a decoder and a computer, and the amount of movement of the object d between the rollers 1 and 2 is digitally displayed on the display section 4 as a numerical value.

In the above example, a through hole 81 is formed as an example of a mark formed on the disk body 8, but such a mark may be a mark that reflects light, a magnetic mark, or the like.

For example, if the mark is a magnetic mark as shown in FIG. 4, the magnetic head 10 can be placed.

The measuring means is not limited to the above example, and the movement of the object d between the length measuring roller 1 and the auxiliary roller 2 is correlated with the rotation of the length measuring roller 1, and the measuring means is not limited to the above example. Any display device may be used as long as the amount of movement of the object to be measured d is displayed through the rotation of the length roller 1.

(Effects) As detailed above, the length measuring instrument of the present invention moves the object to be measured between the length measuring rollers and the auxiliary rollers provided on the upper and lower scissors, and the amount of movement of the object is measured. Since the measuring device is provided with a measuring means configured to measure through the rotation of the length measuring roller, a display section for the measured value, and a reset section, the object to be measured is moved between the length measuring roller and the auxiliary roller. It is a convenient and easy-to-use device that allows you to measure the length of various types of long rope-like bodies with just one device. Furthermore, since the rotation of the length measuring roller is directly displayed as the amount of movement of the object to be measured, the length of the object to be measured can be measured accurately.

Furthermore, a guide is provided on at least one open free end of the scissors so that the object to be measured can be moved between the length measuring roller and the auxiliary roller, so the object to be measured does not come off between the rollers, and the guide Since cutting marks can be placed on the object to be measured using the cutting tool, the object to be measured can be easily cut to a desired length.

Furthermore, in the length measuring instrument of the present invention, the length measuring roller and the auxiliary roller attached to opposite positions of the open free end are biased in the opening direction by a spring interposed between the upper and lower scissors, Since the space between the rollers is maintained in an open state, the object to be measured can be easily mounted between the rollers, and during measurement, the object to be measured can be pushed against the spring force according to the outer diameter of the object to be measured. By manually applying pressure to the upper and lower scissors, the object to be measured can be held between the rollers with an appropriate pinching force, making it easy to operate and preventing excessive pinching force from being measured. Since it does not touch objects, it does not damage the object to be measured, and there is little measurement error regardless of the outer diameter of the object.
