Description

[Detailed description of the invention] (Field of industrial application) This invention prevents the wires from intertwining with each other and making it difficult to pull out various wires stored in a wire storage container in a stacked manner. This invention relates to a pressing device for a wire storage container that is installed inside to prevent accidents that may impede work.

(Prior Art) Conventionally, various wires such as piano wire, steel wire for springs, welding wire, and wire rods whose core wires are coated with synthetic resin are placed in an annular space of a storage container having an inner tube and an outer tube. In order to make it easier to pull it out, it is wrapped and laminated with a twist that exerts a force that spreads outward.

This wire is given a twist that exerts a force that spreads outward, and it is stored relatively loosely in the storage container, so when the wire is pulled out, the wires spring up and become entangled with each other, making it difficult to pull out the wire. If this happens, it will be difficult to pull out the wires, so it is difficult to pull them out.
A holding plate with a wire outlet is equipped near the inner cylinder.

(Problem that the invention aims to solve) However, even if a presser plate is installed on the top of the stacked wires, the top wire near the inner cylinder may shift and become stuck when the wires are being pulled out from the outlet. A part of the wire falls into the gap near the outer wall of the cylinder, and the other part of the wire that falls flies upwards from the outlet and gets entangled with the wire being drawn out, making it difficult to draw out smoothly and hindering work. Accidents that result in

Also, since the wire is twisted, the wire at the top inevitably springs up, but since the entire upper part is pressed by the holding plate, there is no friction between the wire and the holding plate when pulling out the wire. This also has the disadvantage of making the wire to be pulled out heavy.

(Means for Solving the Problems) The present invention has been made by focusing on the above-mentioned problems of the conventional technology. The purpose of the present invention is to solve the above-mentioned problems by applying appropriate pressure with a gap.

The present invention is placed on top of wires that are wound and stacked in a space formed between an inner cylinder and an outer cylinder, and is made of an elastic material and is arranged along the outer wall of the inner cylinder. A rising wall of a required height is provided, and a plurality of pressing pieces are provided that taper outward at required intervals from the lower end of the rising wall and elastically abut against the inner wall of the outer cylinder. This is a pressing device for a wire storage container characterized by the following.

(Function) The pressing device is placed on top of the wire that has been wound and stacked, and presses the top of the wire using the elasticity of the plurality of pressing pieces, so it effectively prevents the wire from bouncing up or popping out. , since the wire near the outer wall of the inner cylinder is pressed near the lower end of the rising wall and the base of the pressing piece, in order to prevent the wire from shifting into the gap near the outer wall of the inner cylinder, Withdrawals can be made smoothly.

In addition, since each pressing piece extends outward in a tapered manner at a required interval from the lower end of the rising wall, the contact resistance between the pressing piece and the wire that springs up during wire withdrawal is reduced, and the wire Withdrawals become easier.

(Example) The present invention will be described in detail below based on an example shown in FIGS. 1 to 4. 1 has a cylindrical bottomed outer cylinder 2 made of fiber or the like and has a required height and inner diameter, and a cylindrical outer cylinder 2 whose lower end is fixed to the bottom of the outer cylinder 2 and is arranged concentrically with the outer cylinder 2. A wire storage container consisting of an inner cylinder 3, in which a twisted wire 5 that exerts a force that spreads outward is wound and laminated in an annular space 4 formed between the outer cylinder 2 and the inner cylinder 3. I store it.

Reference numeral 6 denotes a raised wall 7 of a required height disposed along the outer wall 3a of the inner cylinder 3, and a raised wall 7 extending outward toward the inner wall 2a of the outer cylinder 2 at a required interval from the lower end of the raised wall 7. The inner wall 2a of the outer cylinder 2 extends into a tapered shape of an equilateral triangle.
A plurality of pressing pieces 8 are provided which elastically abut on the
This is a pressing device having a band-shaped rising wall 7 made of a synthetic resin such as vinyl chloride, which has elasticity, and a pressing piece 8 is placed on top of the wire 5 which has been wound and laminated. The wall 7 is surrounded and attached to the outer wall 3a of the inner cylinder 3.

9 is fitted onto the rising wall 7 surrounded by the outer wall 3a of the inner cylinder 3 to fix and press the pressing device 6;
Fixed ring with required height and wall thickness, 10 is outer cylinder 2
The wire 5 which is wound and laminated in contact with the inner wall 2a of
It is a press ring having a required height and wall thickness, which is installed between the outer upper part of the wire 5 and the tip 8a of the press piece 8, and presses the outer circumferential surface of the wire 5.

The wire storage container 1 equipped with the pressing device 6 is
The wires 5 that have been wound and stacked are sequentially pulled out from the gap near the base of the pressing piece 8 for use.

In this case, the pressing device 6 is placed on top of the wound and stacked wires 5, and the elasticity of the plurality of pressing pieces 8 whose bases are pressed by the fixed ring 9 causes the wires to
Since the upper part of the rising wall 7 is pressed, it effectively prevents the wire 5 from bouncing up or popping out, and
Since the wire 5 near the outer wall 3a of the inner cylinder 3 is pressed near the lower end of the pressing piece 8 and the base of the pressing piece 8, the inner cylinder 3
In order to prevent the wire 5 from shifting into the gap 4a near the outer wall 3a, the wire 5 can be drawn out smoothly.

Moreover, each pressing piece 8 extends outward in an isosceles triangular shape and tapering outward at a required distance from the lower end of the rising wall 7, so that the wire 5 that springs up while the wire 5 is being pulled out and each pressing piece The contact resistance with the piece 8 is reduced, and the wire 5 can be easily drawn out.

Further, the pressing ring 16 comes into contact with the inner wall 2a of the outer cylinder 2 and presses the vicinity of the outer circumferential surface of the coil 5 by its own weight and the elasticity of the pressing piece 8, thereby preventing it from jumping out from the vicinity of the outer circumferential surface to the upper surface. At the same time, the coil 5 on the inside from the vicinity of the outer peripheral surface
A space is formed on the upper surface to allow the twisted force of the coil 5 to escape, thereby making it easier to draw out the coil 5.

In the above embodiment, the rising wall 7 of the pressing device 6 is formed into a discontinuous band shape with a portion cut away,
Although the outer wall 3a of the inner cylinder 3 is arranged so that there is no gap at the end 6, some gaps may be provided.
Alternatively, the end portions may be arranged by overlapping each other by an appropriate length, and if necessary, the end portion may be formed into an endless annular shape that fits outside the inner cylinder 3 instead of a band shape.
When the upright upper wall 7 is formed into a band shape, it can be used even if the diameter of the inner cylinder 3 changes to some extent, and it takes up less space for storage and transportation, and it is also cheaper, compared to an endless annular one. There are advantages.

Furthermore, although the pressing device 6 uses a fixed ring 9 that is externally fitted onto the rising wall 7 at the base, the fixed ring 9 may be omitted by making the rising wall 7 thick so that it has its own weight.

The pressing device 6 also includes a pressing ring 10 that contacts the inner wall 2a of the outer cylinder 2, but depending on the type of coil 5, for example, if the coil 5 has relatively little twist or is relatively flexible, You may stop using them together.

Although the pressing device 6 is made of elastic synthetic resin, other materials may be used instead of synthetic resin as long as they have the same characteristics.

Furthermore, although the pressing piece 8 of the pressing device 6 is formed into an isosceles triangular shape, it is not necessarily restricted to this shape as long as it extends outward in a tapered manner.

(Effects of the invention) Since the invention has the above configuration, it has the following effects.

(1) Since the upper surface of the wire is pressed by a resilient pressing piece with an appropriate area, the wire cannot be pulled out in order to reliably prevent the wire from bouncing up, popping out, or shifting around the inner cylinder. Contributes to improving work efficiency by making things run smoothly.

(2) Since the pressing pieces taper outward at required intervals and have an appropriate pressing area, the contact resistance between the wire and the pressing piece is reduced, making it easy to pull out the wire, and the wire pulling device This simplifies the process, reduces power consumption, and contributes to lower operating costs.

(3) It has a simple structure and is easy to manufacture, so it can be provided to customers at low cost.
