Description

  The present invention is a coil-specific protection for protecting a coil formed by winding a metal wire in a substantially cylindrical shape having a predetermined length so that the center line faces in the horizontal direction and covering the arranged coil from above. The present invention relates to a cover member.

  Conventionally, many manufactured coils are piled up and stored. When stacked in this manner, the metal wires may be rubbed unexpectedly and scratches may occur on the metal wires. For this reason, the generation of scratches is prevented by mounting the protective cover on the coil by the protective cover mounting device (see, for example, Patent Document 1).

  However, since the mounting device for the protective cover is very expensive, in practice, before stacking, an operator puts a sheet over the coil so as to cover the coil, and the wires are connected to each other. The current situation is to avoid rubbing directly.

JP-A-6-335727

  As described above, if the worker simply covers the sheet so as to cover one sheet, the sheet is unintentionally displaced with respect to the coil when stacking. For this reason, the position of the sheet relative to the coil must be corrected again, or the coils must be carefully piled up so as not to be displaced, which is a troublesome operation and there is room for improvement.

  Accordingly, the present invention has been made in view of such circumstances, and an object of the present invention is to provide a coil-specific protective cover member that can reliably prevent displacement with respect to the coil.

  The coil-specific protective cover member according to the present invention is a coil formed by winding a metal wire material into a substantially cylindrical shape having a predetermined length so that the center line faces in the horizontal direction, and covers the arranged coil from above. A protective cover member dedicated to a coil for protection, comprising: a cover body configured in a bag shape having an opening by a flexible sheet; and an elastic material for squeezing the opening of the cover body toward a closing side It is characterized by having.

  According to the present invention, the cover body is mounted so as to cover the coil while expanding the opening of the cover body against the force of squeezing the elastic material from above on the coil arranged so that the center line is oriented in the horizontal direction. Let After the cover body is attached, the cover body can be fixed so as not to be displaced with respect to the coil by squeezing the opening of the cover body toward the closing side. Since the cover body is fixed to the coil in this way, the cover body is not displaced relative to the coil when the coils are stacked. Therefore, the coil stacking operation can be easily and quickly performed. When the cover body is unnecessary, the cover body can be quickly removed from the coil by pulling the cover body upward from the coil.

  In the coil-specific protective cover member according to the present invention, it is preferable that the elastic material is provided over substantially the entire periphery of the opening of the cover body.

  As described above, by providing the elastic material over substantially the entire periphery of the opening of the cover body, it is possible to exert a tightening force by the elastic material over the entire circumference of the coil, and the cover is not easily displaced with respect to the coil. Can be in the body.

  Moreover, it is preferable that the protection cover member only for a coil which concerns on this invention is set to the magnitude | size which the said cover body covers to the height direction lower side part of the said coil.

  As described above, by setting the cover body to a size that covers the lower part in the height direction of the coil, the cover body can be covered deeply with respect to the coil. can do.

  Moreover, it is preferable that the coil-specific protective cover member according to the present invention includes an anti-slip portion for preventing slippage with the outer surface of the coil on the inner surface of the cover body.

  As described above, by providing the inner surface of the cover body with the anti-slip portion for preventing slippage with the outer surface of the coil, the inner surface of the cover body can be made difficult to slide against the outer surface of the coil. Thus, the cover body can be made more difficult to be displaced.

  As described above, according to the coil-specific protective cover member according to the present invention, the cover body is fixed to the coil by simply squeezing the opening of the cover body with an elastic material toward the closing side only by mounting the coil so as to be covered with the cover body. Therefore, it is possible to provide a useful coil-specific protective cover member that can reliably prevent displacement with respect to the coil, particularly when the coils are stacked.

The coil exclusive protection cover member of this invention is shown, (a) is a side view, (b) is a bottom view. The state which mounted | wore the coil with the protection cover member only for the coil is shown, (a) is a front view, (b) is a side view. It is a front view which shows the state which piled up three coils with which the protective cover member only for the said coil was mounted. It is the front view which mounted | wore the coil with the protective cover member only for a coil of another form.

  Hereinafter, the coil-specific protective cover member according to the present invention will be described with reference to the drawings. As shown in FIGS. 1A and 1B, the coil-specific protective cover member includes a cover body 2 configured in a bag shape having an opening 2K by a flexible sheet, and an opening 2K of the cover body 2. And an elastic material 3 for squeezing toward the closing side. By covering the cover body 2 on the coil 4 (see FIGS. 2A and 2B) from above, the coil 4 can be protected.

  As shown in FIGS. 2A and 2B, the coil 4 is formed in a substantially cylindrical shape having a predetermined length by winding a metal wire 4A. And many manufactured coils 4 are piled up and stored. For example, FIG. 3 shows a state in which three coils 4, 4 and 4 are stacked in two upper and lower stages (may be stacked in three or more stages). When the coils 4 are stacked in this manner, the cover body 2 can be fixed to the coils 4 by covering the coils 4, 4 and 4 with the cover body 2, so that the cover body 2 is positioned relative to the coils. There is no deviation. Therefore, the mounting operation of the cover body 2 to the coil 4 can be performed easily and quickly. In addition, the metal wires 4A, 4A of the coils 4, 4, 4 protected by the cover body 2 are not directly rubbed, and the coil surface can be prevented from being damaged. Although not shown, the coil 4 that is formed into a substantially cylindrical shape by winding the metal wire 4A is bound by a plurality of binding bands (not shown) so that the adjacent metal wires 4A in the longitudinal direction do not fall apart. . Here, a case where the coils 4 are stacked is shown, but a case where the coils 4 are not stacked may be used.

  The cover body 2 is made into a bag shape after making a flexible sheet with a polyester resin, which is a heat-resistant material. In the case where the cover body 2 is covered with the high-temperature coil 4 immediately after being manufactured, the cover body 2 is not deformed or contracted by the heat of the coil 4 when the heat-resistant material is configured as described above. preferable.

  Further, as shown in FIGS. 1A and 1B, the cover body 2 has a substantially rectangular outer shape in a plan view and is formed in a bag shape having an elliptical opening 2K at the lower end. And it is set to the magnitude | size which covers even the lower side part which becomes the lower side rather than the position of the height direction half of the coil 4 with the cover body 2. FIG. Thus, by setting the cover body 2 to a size that covers the lower portion of the coil 4 in the height direction, the cover body 2 can be covered deeply with respect to the coil 4. Thus, the cover body 2 that is difficult to be displaced can be obtained.

  Further, the inner surface of the cover body 2 is provided with a slip prevention portion 5 (a portion surrounded by a broken line in the figure) for preventing slipping with the outer surface of the coil 4. The anti-slip portion 5 is formed integrally with the cover body 2 by sticking a rubber sheet with an adhesive or the like, or by applying molten silicon rubber, butyl rubber or the like to the inner surface of the cover body 2. Thus, by providing the slip prevention part 5 on the inner surface of the cover body 2, it is possible to make the inner surface of the cover body 2 difficult to slide with respect to the outer surface of the coil 4, and the position shifts with respect to the coil 4 accordingly. A difficult cover body 2 can be obtained. The cover body 2 configured in this manner is attached to the coil 4 placed horizontally so that the center line faces the horizontal direction from above.

  The elastic member 3 is made of a band-shaped rubber, and is provided on the inner surface side of the peripheral edge of the opening 2K of the cover body 2 so as to cover substantially the entire periphery of the peripheral edge of the opening 2K of the cover body 2. By providing this elastic material 3 over substantially the entire periphery of the opening 2 </ b> K of the cover body 2, the tightening force by the elastic material 3 can be exerted over the entire circumference of the coil 4, and the position of the coil 4 is shifted. A difficult cover body 2 can be obtained.

  When the coil-specific protective cover member 1 configured in this way is attached to the coil 4 by, for example, two workers, first, the coil-specific protective cover member 1 with the opening 2K facing downward is provided above the coil 4. Position. In this state, both ends of the coil-specific protective cover member 1 are grasped by two workers and pulled together to cover the lower part of the coil 4 while expanding the opening 2K against the force of the elastic member 3 squeezing. Covering the cover body 2 with the coil completes the mounting of the coil-specific protective cover member 1.

  In addition, when the coil-specific protective cover member 1 is attached to the coil 4 by one person, for example, the coil-specific protective cover member 1 corresponding to the coil-specific protective cover member 1 can be covered so as to cover the lower portion of one end in the longitudinal direction of the coil 4. Cover one end and temporarily fix. While opening the opening 2K from this state, the other end of the coil-specific protective cover member 1 is covered so that it can cover the lower side of the other end of the coil 4 in the longitudinal direction. Is completed.

  FIGS. 2A and 2B show a state where the coil-specific protective cover member 1 is attached to the coil 4. The front and rear side portions 2A and 2B of the cover body 2 cover the metal wires 4A and 4A located at the front and rear ends. Further, the left and right side surface portions 2C and 2D of the cover body 2 cover the positions close to the lower ends of all the metal wire rods 4A arranged in the front-rear direction, that is, the lower side portions.

  The coil-specific protective cover member according to the present invention is not limited to the above embodiment, and various modifications can be made without departing from the gist of the present invention.

  In the said embodiment, although the cover body 2 was produced from the polyester resin which is a heat resistant material, you may produce with other various synthetic resin materials. Further, the cover body 2 may be waterproofed. Moreover, the shape of the cover body 2 is optimal as long as it can be covered along the outer shape of the coil 4, but may be any shape.

  Moreover, in the said embodiment, it is a cover body so that the opening part for lifting the coil 4 from the opening of the front-and-rear end of the coil 4 can be inserted, and the opening of the front-and-rear end of the coil 4 is not covered completely. 2, the cover body 2 may completely cover or substantially cover the opening at the front and rear ends of the coil 4.

  Moreover, in the said embodiment, although the slip prevention part 5 was provided in the inner surface of the cover body 2, the cover body 2 which is not provided with the slip prevention part 5 may be sufficient.

  Moreover, in the said embodiment, although the elastic material 3 was comprised from strip | belt-shaped rubber | gum, an elastic material can also be comprised from the springs, springs, etc. which are metal or synthetic resin.

  Moreover, in the said embodiment, although it was the structure which prevents the cover body 2 being displaced with respect to the coil 4 by the force which squeezes the opening 2K of the elastic material 3 to the closing side, both ends of the cover body 2 are further connected. By providing a pair of connecting members 6, 7 to be connected to both ends of the cover body 2, the cover body 2 can be further prevented from being displaced. In this case, the male hook-and-loop fastener 8 is provided at the tip of one connecting member 6, and the female hook-and-loop fastener 9 that can be freely attached to and detached from the male hook-and-loop fastener 8 is provided at the tip of the other connecting member 7. .
