Description

In the present invention, a winding body unwinding that accommodates and supports an electric wire bundled several times, or a wire material, a pipe material, or the like (hereinafter referred to as a winding body H), such that they can be unwound generally in a tangential direction. For example, when performing wiring work while unwinding the bundle body, the amount of use of the bundle body H can be measured so that the amount of use of the bundle body unwind drum apparatus can be measured. A length measuring machine is partly attached. Especially, the length measuring machine is compact, weighing, inexpensive, and detachable. In addition, the wire is pulled out smoothly without any support in wiring work. The present invention relates to a winding body unwinding drum device including a length measuring device that is configured so as to obtain an accurate length.

Conventionally, when performing wiring work while unwinding the wound body H accommodated and supported in the wound body unwinding drum device, it may be necessary to measure the amount of use. Conventionally, as a method of measuring the amount of wire used in such a case, the following method of measuring the amount of wire used is broadly known.
(1) A calculation method from construction drawings given by a construction company or the like.
(2) After construction, an actual measurement method using a length measuring means such as a scale or a tape measure.
(3) Length measurement is calculated using a length measuring machine during wiring construction.

However, the above-described conventional wire usage measurement methods have the following problems.
According to the method of (1) calculating from the construction drawing,
(A) Since it is calculated based on the scale drawing, an error has occurred.
(B) When a construction change is made with respect to the original construction drawing, the calculation method based on the construction drawing must be actually measured and is troublesome twice, unlike the actual construction drawing.
According to the above method (2) after construction, according to the method of actual measurement at the construction site,
(A) Depending on the complexity of the complicated construction site and the building, the ceiling, wall surface, etc. are often already hidden, so accurate measurement is impossible and only approximate calculation is possible. Absent.
According to the above (3) method for calculating length using a length measuring machine at the time of wiring construction,
(A) Currently, when wiring is performed using an unwinding drum device such as a wiring reel, the length measuring machine is provided as a single unit separated from the wiring reel and is used as a completely separate unit. ing. In this case, since there are various types of wire materials to be measured, such as their materials and thicknesses, the longer the wire material, the less flexible and flexible. It was dragged in the direction of pulling out, and it moved or overturned, making smooth drawing and measurement extremely difficult. In order to solve this problem, the length measuring device has been increased in size or weight to be stabilized. However, such a large or heavy length measuring instrument is expensive and hinders carrying and handling, and is hardly used at construction sites.
(B) In the case of a talai-type winding body unwinding drum device that covers the side surface, a device is proposed in which a drawer hole is provided on the side surface and the length measuring device is directly fixed to the outlet by screwing . This direct connection type has the following problems. First, if the diameter of the drum device and the diameter of the bundle H are substantially the same, there is no gap and it is difficult to insert the wire into the drawing hole. Second, the drawing hole for the wire is structurally Since the length measuring machine is fixed to the drum device, there is no room for it, and when pulling the wire etc. Cannot be pulled out easily, and there is a problem of lack of workability. Thirdly, since the length measuring device is fixed to the wiring reel, it cannot be diverted to other wiring reels and lacks in compatibility. On the other hand, it was necessary to equip one measuring machine, which was a big problem in terms of cost.

For example, in Patent Document 1, the long cable such as an electric cable or wire used at a construction site or the like is collected intensely under various conditions during the work when collecting the long cable after the work is finished. Twisted. In such a case, the twisted cable winder is configured to wind the long cable while returning the twist. In this twist-back cable winder, in claim 4 of the present invention, a configuration is disclosed in which the cable winder includes a device for measuring the length of a cable wound in a drum. The device described in Patent Document 1 is a winding device that collects a long cable or the like, and is only a configuration in which a length measuring device is directly fixed to the winding device.

On the other hand, the one described in Patent Document 2 relates to a wire take-up device with a length measuring device that draws and winds a wire from a wire drum by a necessary length, and specifically, a wire drawn from a wire drum. A take-up reel, a length measuring roller disposed in front of the take-up reel and elastically biased toward the electric wire, and a length of electric wire being measured based on the number of rotations of the length measuring roller It consists of an encoder, an electric wire holder that receives the electric wire pressed by the length measuring roller, a guide roller that is arranged in front and rear of the length measuring roller and guides the feeding of the electric wire, and a cutter that cuts the electric wire. It is a feature. The one described in Patent Document 2 is to measure the amount of winding when the wire wound around the wire drum is wound up to a required length, using the device, and at the wiring construction site. This is different from the device for feeding out the wire housed and supported in the unwinding drum device while measuring the wiring length, and, like the one described in Patent Document 1, the length measuring machine is attached to the winding device. It is only the structure of fixing directly.
