Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a roll wire holding device, and more particularly, to a roll wire holding device having a plurality of drums for detachably holding a roll wire.

[0002]

[Prior art]

 For example, when arranging the shape of a bonsai tree, several types of wires with different thicknesses are selectively used according to the type and part of the tree and the desired shape. Therefore, when performing such work, it is necessary to prepare several kinds of wires in advance, place them close to each other, select a wire with a thickness suitable for the purpose, and cut it to the required length. .

By the way, conventionally, the wire is provided in the form of a roll wire wound into a roll. Rolled wires up until a while ago were often provided in large winding sizes, so a roll wire holding device was proposed to rewind the purchased rolled wire into a size suitable for bonsai work and the like. This device consists of a drum for winding the wire and a handle, etc. It is designed to wind an appropriate amount of wire on the drum, pull out the wound wire to the required length, and cut it.

[0004]

[Problems to be solved by the device]

 However, in recent years, it has become common for roll wires to be provided with a winding diameter of several tens of centimeters. Therefore, the conventional roll wire holding device that rewinds and uses the roll wire is not suitable. It's gone. Therefore, there is a demand for the development of a roll wire holding device suitable for a roll wire of a general size today.

In order to meet this demand, it is conceivable to change the size of the drum holding the roll wire. However, since the inner diameter of the roll wire varies depending on the thickness even if the length is the same, there is a problem that one type of drum cannot support a plurality of roll wires having different thicknesses. Further, when the wire is pulled out from the roll wire held by the drum, there is a problem that the rotating inertia acts on the rotating drum, and the wire is pulled out or entangled more than necessary.

The present invention has been made in view of the above-mentioned problems of the related art, and one type of drum can firmly hold a plurality of roll wires of different sizes, and the wires are unnecessarily exposed. The aim is to provide a roll wire holding device that does not have any.

[0007]

[0011]

[Embodiment of the invention]

 A roll wire holding device 1 according to an embodiment of the present invention will be described with reference to the drawings. The roll wire holding device 1 includes five drums 5 to which one roll wire 3 (see FIGS. 2 to 4) is mounted, a support stage 7 for rotatably supporting the drum 5, and a support stay 7. It is composed of a base 9 to which is fixed, a gate frame 11, and a brake plate 13 for giving a light load to the rotation of the drum 5.

The drum 5 is mounted between the main side plate 15 and the sub side plate 17, the cylindrical boss shaft 19 that passes through the central portions of the main side plate 15 and the sub side plate 17, and the two side plates 15 and 17. It is composed of three spool pins 21 provided in a bridge shape, an inner nut 23 and an outer nut 25, and a coil spring 27. The main side plate 15 and the sub side plate 17 are formed of a metal plate in a disk shape having the same size as each other, and the central portion of the main side plate 15 is stamped so as to form a flat truncated cone shape (see FIG. 5).

The nuts 23 and 25 are formed in a flat plate shape having a substantially three-lobed shape, and the center hole thereof is a screw hole.

The boss shaft 19 is formed by coaxially integrally forming a large-diameter portion 29 forming the main portion and a relatively short small-diameter portion 31 protruding from both ends of the large-diameter portion 29. A portion of the portion 29 that is biased toward one end is a screw shaft portion 33. One small-diameter portion 31 of the boss shaft 19 is passed through the center hole 35 (see FIG. 5) of the main side plate 15 from the recess 37 side of the embossed portion, and the portion continuous with the small-diameter portion 31 is the main side plate in the recess 37. It is welded to 15. Therefore, the boss shaft 19 is provided on the main side plate 15 in a state of vertically projecting from the central portion of the main side plate 15.

The coil spring 27 is externally inserted into the large diameter portion 29 of the boss shaft 19, and the inner nut 23 is screwed into the screw shaft portion 33 from that state, whereby the coil spring 27 is compressed. The screwing amount of the inner nut 23 is adjusted according to the total width of the roll wire to be mounted on the drum 5. Then, from this state, the portion of the large diameter portion 29 of the boss shaft 19 protruding from the inner nut 23 is inserted into the center hole 39 of the sub side plate 17, and the outer nut 25 is screwed onto the screw shaft portion 33. When the outer nut 25 is tightened against the inner nut 23 with the sub side plate 17 sandwiched therebetween, the two side plates 15 and 17 are fixed to each other via the boss shaft 19. At this time, since the inner nut 23 is given a load of rotation due to the pressing force of the coil spring 27, the sub side plate 17 and the outer nut 25 can be stably assembled.

The spool pin 21 includes a columnar pin body 41 and a mounting nut 43 (see FIG. 5). The pin body 41 has a length slightly shorter than the large diameter portion 29 of the boss shaft 19, has a screw hole 45 formed in one end surface thereof, and has a knurled portion formed in the outer peripheral surface of the other end side substantially half portion thereof. There is.

Reference numeral 47 denotes a pin mounting groove formed on the main side plate 15. The pin mounting groove 47 is for fixing one end of the spool pin 21 in a position-selectable manner, and the boss shaft 19 is centered at a position approximately in the middle between the center of the side plates 15 and 17 and the outer peripheral edge. There are three equal intervals in the circumferential direction. These pin mounting grooves 47 are composed of a main groove 49 extending in the radial direction of the side plate 15 and three branch grooves 51, 53, 55 continuous with the main groove 49. One of the branch grooves 51 extends from a position of the main groove 49 near the end on the outer peripheral edge side of the side plate 15 in a direction inclined by about 45 ° with respect to the main groove 49, and another branch groove 53 is the main groove 49. The branch groove 55 extends from a position near the end on the boss shaft 19 side in a direction inclined by about 45 ° with respect to the main groove 49, and the other branch groove 55 extends from the branch point of the main groove 49 and the branch groove 53 to the branch groove 53. It extends in almost opposite directions. Each of these branch grooves 51, 53, 55 has a length of about one-third or less than the entire length of the main groove 49. The width of the pin mounting groove 47 is constant at any portion, and the width thereof is substantially the same as the shaft portion 57 (see FIG. 5) of the mounting nut 43 of the spool pin 21.

Both end portions 49a, 49b of the main groove 49 and the respective tip portions 51a, 53a, 55a (see FIG. 6) of the branch grooves 51, 53, 55 are pin mounting portions, and these five pin mounting portions 49a. , 49b, 51a, 53a, 55a are different in distance from the boss shaft 19. That is, this distance is the shortest in the first pin mounting portion 49a forming the end portion of the main groove 49 on the boss shaft 19 side, and then in the second pin mounting portion 53a forming the tip portion of the branch groove 53 The third pin attachment portion 55a forming the tip end portion of 55 and the fourth pin attachment portion 51a forming the tip end portion of the branch groove 51 gradually become longer in this order, and form the other end portion of the main groove 49. The fifth pin attachment portion 49b is the longest.

The spool pin 21 is attached as follows. The shaft portion 57 of the mounting nut 43 is inserted into the pin mounting groove 47 from the outside and is screwed into the screw hole 45 of the pin body 41 to be tightened. As a result, the mounting nut 43 and the pin body 41 are pressed against each other by sandwiching the side edge of the pin mounting groove 47, so that the spool pin 21 is fixed to the main side plate 15 and the pin body 41 moves from the main side plate 15 to the sub side plate 15. The posture is such that it projects vertically toward the side 17. In this way, the three spool pins 21 are individually attached to the three pin mounting grooves 47. The attached spool pin 21 can be moved along the pin attachment groove 47 by slightly loosening the attachment nut 43 and the pin body 41.

The position at which the spool pin 21 is attached depends on the size of the roll wire 3 to be attached to the drum 5 and is one of the five pin attachment portions 49a, 49b, 51a, 53a and 55a of the pin attachment groove 47. Select from. All three spool pins 21 should be attached to the pin attachment parts in the same order. FIG. 6 shows the mounting position of the spool pin 21 according to the inner diameter size of the roll wire 3. When the inner diameter is 120 mm, the spool pin 21 is mounted on the first pin mounting portion 49a, and when the inner diameter is 130 mm, the second pin mounting portion 49a is mounted. If the inner diameter is 145 mm, the third pin mounting portion 55a is used. If the inner diameter is 200 mm, the fourth pin mounting portion 51a is used. If the inner diameter is 210 mm, the fifth pin mounting portion 53a is used. The spool pins 21 are attached to the pin attachment portions 49b, respectively. The mounting position of the spool pin 21 may be changed by slightly loosening the tightening of the mounting nut 43 and the pin body 41. It should be noted that the attachment position of the spool pin 21 need not be changed unless the inner diameter of the roll wire attached to the drum changes.

The sub side plate 17 is provided with 15 pin insertion holes 59. These pin insertion holes 59 have a circular shape slightly larger than the outer diameter of the pin body 41 of the spool pin 21, and the phase of the arrangement with respect to the center of the sub side plate 17 is that all 15 pin attachments with respect to the center of the main side plate 15 are made. It matches the phase of the arrangement of parts. Therefore, in the state where the main side plate 15 and the sub side plate 17 are coaxially located, if one pin insertion hole 59 is positioned on the central axis of one pin attachment portion, all the remaining pin insertion holes 59 The center is individually aligned with the centers of the remaining pin mounts.

The tip end portion of the spool pin 21 attached to the main side plate 15 is inserted through a pin insertion hole 59 (see FIG. 5). As a result, both ends of the spool pin 21 are separately supported by the main side plate 15 and the sub side plate 17 to form a so-called double-sided support structure.

The base 9 has a certain height, and the upper surface thereof has a rectangular flat plate shape that is long in the left-right direction. Six support stays 7 are fixed to a substantially middle portion of the upper surface of the base 9 in the front-rear direction. These support stays 7 have a length substantially the same as the length of the large diameter portion 29 of the boss shaft 19 of the drum 5. They are arranged in a line in the left-right direction at intervals. Therefore, there are a total of five spaces between the two adjacent left and right support stays 7, and approximately half of the space with the center of the drum 5 as a boundary fits in this space.

The support stay 7 has a length slightly larger than the radii of the side plates 15 and 17 of the drum 5, and the shape seen from above is a C-shaped steel plate that opens laterally at the left and right ends. Other than that, it has a generally U-shape that opens rearward. A bearing notch 61, which is substantially Y-shaped when viewed in the left-right direction, is formed at the upper end of each of the support stays 7. Therefore, there are 10 bearing notches 61 in total. The bottom edge of the bearing notch 61 has an arc shape.

The drum 5 is rotatably supported by the support stay 7 by placing the small diameter portions 31 of the boss shaft 19 on the bearing notches 61 of the support stay 7. Specifically, the drum 5 has its axial direction extending in the left-right direction, and approximately half of the drum 5 with the center as a boundary is housed between two adjacent support stays 7, and in that state, the drum 5 is positioned on both left and right sides. The small diameter portion 31 of the boss shaft 19 is placed in the two bearing notches 61. FIG. 1 shows a state in which all of the five drums 5 are supported by the support stay 7.

The gate frame 11 has a gate shape that is long in the left-right direction, and the lower ends of both left and right sides of the gate frame 11 are fixed to the base 9 so that the gate frame 11 is erected at the front end of the base 9. Reference numeral 63 indicates a beam portion of the gate frame 11, and the beam portion 63 is located at a height slightly lower than the top portion of the drum 5 supported by the support stay 7. Reference numeral 65 denotes a wire drawing port formed in the beam portion 63 of the gate frame 11, and a synthetic resin ring is press-fitted into the hole formed in the beam portion 63 so that the sliding property is improved. Five wire outlets 65 are provided at positions corresponding to the respective drums 5.

The brake plate 13 (see FIG. 5) is composed of a fixed portion 67 having a length substantially equal to the length of the base 9 in the left-right direction and five contact portions 69 integrally formed by a leaf spring material. The fixing portion 67 is fixed to the rear end portion of the upper surface of the base 9. The contact portions 69 extend obliquely upward and rearward from the front end of the fixed portion 67 in a state where they are aligned in the left-right direction at regular intervals, and when the drum 5 is placed on the support stay 7, the side plate of the drum 5 is formed. The outer peripheral edges of 15 and 17 lightly press the contact portion 69, so that the contact portion 69 is relatively pressed against the drum 5. Therefore, a light load is constantly applied to the drum 5 by the brake plate 13.

Next, a method of using the roll wire holding device 1 configured as described above will be described. First, the roll wire 3 is attached to the drum 5. In order to carry out this mounting, as shown in FIG. 3, first, the outer nut 25 and the sub side plate 17 are removed from the boss shaft 19, and in this state, the roll wire 3 is fitted onto the three spool pins 21. At this time, if the mounting positions of the three spool pins 21 do not match the inner diameter size of the roll wire 3, the positions of the spool pins 21 are changed. Further, the inner nut 23 is rotated in the axial direction so that the total width W (see FIG. 3) in the axial direction of the roll wire 3 (see FIG. 3) is approximately equal to the dimension between the two side plates 15 and 17, and the gap is increased. Adjust.

Then, the sub side plate 17 and the outer nut 25 are attached to the boss shaft 19 to assemble the drum 5, and then the drum 5 is placed on the support stay 7. Since five drums 5 are prepared in total, the roll wire 3 can be mounted on up to five sizes at one time. Therefore, it is possible to install two or more of the frequently used sizes at the same time. The order in which the drums 55 with the roll wires 3 mounted thereon are arranged may be arbitrarily selected according to the convenience of use, but the wire 71 is oriented toward the front from the top of the winding ( (See FIG. 4).

After the drum 5 is placed on the support stay 7, the wire 71 having an appropriate length is pulled out from the roll wire 3 and is passed through the wire outlet 65. As a result, the tips of the wires 71 of various sizes are positioned side by side in a line. Therefore, the wire 71 of a desired size is pulled out for a required length, cut and used. At this time, the wire 71 moves while rubbing the inner peripheral surface of the wire drawing port 65, but since the wire drawing port 65 is made of synthetic resin, the wire 71 is not damaged and the resistance is small. Therefore, the wire 71 can be pulled out smoothly. Further, although the drum 5 is rotated as the wire 71 is pulled out, a slight load is applied to the drum 5 by the brake plate 13, so that the inertia of rotation is almost suppressed, and therefore the drum 5 is longer than the pulled length. The wire 71 does not come out. The strength of this load can be adjusted by changing the inclination of the contact portion 69 of the brake plate 13 in the initial state.

Although the embodiment of the present invention has been described in detail above, the specific configuration is not limited to this embodiment, and there are design changes without departing from the gist of the present invention. Is also included in the present invention.

[Effect of the invention]

 As described above, according to the present invention, a plurality of roll wires having different wire diameter sizes can be collectively arranged while being held by a plurality of rotatable drums separately. Therefore, the wire can be taken out only by pulling the required amount of the desired wire, and the workability is good. Further, the work for mounting the roll wire on the drum is completed by fitting the roll wire onto a plurality of spools with the two side plates separated from each other and then reassembling the two side plates. Moreover, the distance between the side plates of the drum is adjustable, and the diameter of the drum core can be adjusted by changing the mounting position of the spool pin, so only one type of drum is required, and the manufacturing cost is reduced accordingly. Can be kept low.

According to the second aspect of the present invention, the spool pin mounting position is changed by moving the spool pin along the groove while slightly loosening the tightening between the pin body and the nut. By simply re-tightening the pin body and the nut, the work of adjusting the diameter of the drum core to the diameter of the roll wire can be done easily, and it is not necessary to remove the spool pin from the side plate. You can prevent losing the pin.

According to the invention of claim 3, the drum is rotated with the pulling out of the wire, but since the load is applied to the drum by the brake plate, the inertia of rotation is almost suppressed, and therefore, The wire will not be unwound beyond the length it is pulled out, so there is no need to take extra care when pulling out the wire.

According to the invention of claim 4, when a wire of an appropriate length is pulled out from the roll wire and is passed through the wire outlet, the tip ends of the wires of various sizes are aligned in a horizontal row. Therefore, usability is further improved.
