Description

  The present invention relates to a cable reel for transporting and storing cables, ropes, hemp cords or other elongated materials.

  A conventional reel 100 is shown in FIG. The reel 100 includes a 101a flange, 102 pillars, and a 101b flange. FIG. 16 is a cross-sectional view showing a state in which the wire 106 is wound around the reel 100. The wire stopper 103 is a part that stops the final end of the wire.

  The flange 101a and the flange 101b are located at both ends of the column 102 and hold the wire 106 wound around the column 102. The wire 106 is a wire such as a metal wire, cable, or rope. The reel 100 around which the wire 106 is wound is manufactured by a wire supply manufacturer, transported to an assembly manufacturer, and the wire 106 is used for assembling various products.

  The reel 100 is integrally formed of a resin material and is discarded after use. It is considered that it is environmentally and cost-effective to provide the reel 100 by reusing the reel 100 and winding the wire 106 around the reel 100 again. However, the reel 100 has a large volume, and even if the wire 106 is not wound, the size does not change. Therefore, a high transportation cost is required to return the reel 106 to the original supplier after use. Due to this, the reel 100 is discarded without being reused.

  References 1 to 4 describe the reel 100 that can be disassembled in order to reduce transportation costs. As a representative, the structure of Document 1 will be described with reference to FIG. The pillar 102, the flange 101a, and the flange 101b are combined at the pillar 102. The pillar 102 can be deformed, the interval between the flange 101a and the flange b is maintained, and the pillar 102 is deformed, whereby the reel 100 can be disassembled and assembled.

  However, the reel of Document 1 is not easy to disassemble and assemble. It is necessary to push and bend the pillar 102, deform it into this shape, and assemble and disassemble it. Further, since it is bent and deformed, it is weak in strength. There is a problem that it cannot withstand repeated use. In other documents, too, a large number of concave portions and convex portions are provided and combined by a nested structure, and joined by a third member such as a screw or a bolt. However, they are weak in strength or complex to assemble.

(Overall structure)
FIG. 1 is an exploded view of the reel 100 of the present invention. 1A is a 101a flange (upper flange), FIG. 1B is a 102a column and a 102b column, FIG. 1C is an inner shaft 107, and FIG. 1D is a 101b flange (lower flange). ). All are made of resin material and can be made by resin molding.

  The pillar 102 combines the pillar 102a and the pillar 102b to form one hollow cylindrical pillar 102. On both end faces of the pillar 102, there are a flange 101a and a flange 101b, respectively. The pillar 102 has a hollow cylindrical shape.

  The inner shaft 107 has a hollow cylindrical shape. An inner shaft 107 is provided inside the pillar 102. Since the size thereof is smaller than that of the reel 100, it is not deformed and can be made strong and strong. When setting the reel 100 in the machine, the cavity of the inner shaft 107 may be used.

The flanges 101a and 101b are disk-shaped. Various protrusions and recesses are provided so that the pillar 102 and the inner shaft 107 can be combined. Details of each will be described below.
The inner shaft 107 is not an essential component but is advantageously present.

(Pillar 102)
FIG. 2 is a top view of the pillar 102 portion. The pillar 102 includes a pillar 102a and a pillar 102b which are two parts. Each column portion is provided with five fitting convex portions 105. The number is not limited to an example. One key part 104a and one key part 104b are provided at the top of each pillar part. The structure on the back is the same. Rails 301a and 301b are also provided. The details will be described with reference to FIG.

  The pillar 102a and the pillar 102b are parts constituting the pillar 102, and in this example, are divided into first and second parts. Dividing into two is best considering the efficiency during assembly and disassembly. However, it can be divided into three or four.

  FIG. 3 is a three-dimensional view showing the inner surface of the pillar 102a. The pillar 102a and the pillar 102b have the same structure. The inner wall has two rails, rail 301a and rail 301b. A plurality of fitting convex portions 105 are provided between the upper surface and the lower surface of the rail and the pillar. Furthermore, it has two key parts 104a at the top and bottom. Two key portions 104a are provided on the target, one each on the top and bottom. A mating concave portion 303 and a mating convex portion 302 are provided on the mating surface 310 of the pillar 102a and the pillar 102b.

  One set of the alignment concave portion 303 and the alignment convex portion 302 is provided on one alignment surface 310 and aligned. On the other surface, a pair of a mating recess 303 and a mating projection 302 is provided in the reverse order. By combining the mating recess 303 and the mating projection 302, the columns 102a and 102b are combined. To do. Since it is a set of irregularities, it is easy to combine.

  The inset projection 105 is a projection for combining the flange 101 and the column 102, and in this example is a quadrangular column. The fitting convex portion 105 a is located at the end of the column 102. Details will be described with reference to FIG.

  The key portion 104a and the key portion 104b are for fixing the pillar 102 and the flange 101, and are formed with protrusions or inclined portions such that the tip is hooked as indicated by arrows. Details will be described with reference to FIG.

  The rails 301 are provided at two places above and below the entire circumference of the pillar 102. It is plate-shaped and ensures the strength of the pillar 102a. The rail supports the key portion 104. Two or more rails may be used, but two columns are the best because the pillar 102 is difficult to bend. Three or more locations are possible.

(Inner shaft 107)
FIG. 4A shows the inner shaft 107. FIG. 4B is a view showing the bearing portion 206 provided on the flange 101. The inner shaft 107 connects the flange 101a and the flange 101b together with the pillar 102. The inner shaft 107 is located inside the pillar 102.

  The inner shaft 107 includes an inner shaft recess 108a and an inner shaft main body 108b. The bearing portion 206 includes a bearing convex portion 211a and a bearing body 211b. The bearing convex portion 211a and the inner shaft concave portion 108a are combined and connected. The combination can be easily assembled by simply inserting the inner shaft 107 into the bearing projection 211a.

(Flange)
5 and 6 show the front surface (outer surface) and the back surface (inner surface) of the flange 101, respectively. The flanges may have the same flange structure for the two flanges at both ends of the column 102, and only one type of processing is required. Since either can be used as a part, it is easy to replace and there is no mistake.

  The flange surface in FIG. 5 has a large reinforcing recess 212a and a small reinforcing recess 212b on the entire periphery. The inner periphery is composed of six fan-shaped regions, and three portions having large openings and other regions having the reinforcing portions 203 and the transport holes 213 are alternately arranged in the other regions. The flange 101a and the flange 101b are in a positional relationship exactly rotated 180 degrees, and the fan-shaped regions are also shifted between the flanges, which is good in strength. Both the weight reduction and strength improvement of the flange 101 are satisfied by the reinforcement recesses and the arrangement of this region. In addition, the flange surface has a key release portion 204 at two locations, a bearing portion 206 at the center, and eight confirmation windows 214. The wire stopper 103 is a hole provided at twelve locations on the outer peripheral portion of the flange 101 and is a portion that stops the final end of the wire 103. The wire 106 can be stopped at any part. Since the flange 101 is processed separately from the main body reel 100, many holes can be processed.

  The large reinforcing concave portion 212a and the small reinforcing concave portion 212b are located on the outer peripheral portion of the surface of the flange 101, and are used to increase the strength of the flange 101, and have a trapezoidal shape and a concave shape.

  The reinforcing part 203 is provided in two places. This is for deforming the key release unit 204, for increasing the strength, or for assisting when the key release unit 204 is deformed.

  The transport hole 213 is a hole used for transporting the reel 100 at one place. Since the positions at the flange 101a and the flange 101b are reversed, it is easy to hold.

  There are two key release portions 204 on one flange, and by pushing this portion into the inside of the reel 100, the key portion inside the reel 100 is pushed and fixed. Details will be described with reference to FIG.

  The bearing portion 206 is located at the center and is a portion combined with the inner shaft 107, as described in FIG.

  The confirmation window 214 is an opening provided in the flange 101, and it can be confirmed whether the flange 101 and the column 102 are fixed by looking at the fitting convex portion 105 through the opening. Details will be described with reference to FIG.

  Further, a display portion 221 indicating the opening / closing direction is shown on the reinforcing portion 203. Since the reel 100 of the present application is made of a resin material and repeatedly used, if the display portion 221 indicating the opening / closing direction is not shown, there is a high possibility that a part of the reel will be damaged.

  Furthermore, a key release unit support 280 is provided on the reinforcement unit 204. The key release unit support 280 limits the degree of pressing when the key release unit 204 is pushed in. The key release unit 204 is a long and thin bar made of resin and breaks if pushed too much. Therefore, the key release unit 204 is restricted by a key release unit support 280 so as not to be broken. The key release unit support 280 is provided with a reinforcing unit 203. Details are shown in FIG.

  A support protrusion 207, a large guide 210a, a small guide 210b, a key holding portion 201, a fitting concave portion 202, and a groove 209 are provided on the rear surface of the flange shown in FIG.

  The support protrusion 207 is a portion provided at the target in two places so that the flange 101 and the pillar 102 are not separated in the direction perpendicular to the flange surface. Details will be described with reference to FIG.

  The large guide 210a and the small guide 210b are like a protrusion or a wall that holds the pillar 102 together with the groove 209. Two large guides 210a and two small guides 210b are provided circumferentially with two gaps therebetween. A key holding unit 201 and a key releasing unit 204 are provided between the large guide 210a and the small guide 210b.

  The key holding portion 201 is a portion that is combined with the key portion of the column 102 and is a portion that restricts the flange 101 and the column 102 from rotating in a direction parallel to the flange surface. Details will be described with reference to FIG.

  The inset recess 202 is a portion combined with the inset protrusion 105 of the column. Details will be described with reference to FIG.

  The groove 209 is a recess and is a portion where the pillar 102 is set in the recess. Provided all around the flange.

  Between the six fan shapes, there is a convex portion of the frame 270, which has a reinforcing effect.

(Column and flange)
FIG. 7 shows the relationship between the pillar 102 and the guide 210. FIG. 7A is a cross-sectional view taken along the line aa ′ in FIG. FIG. 7B is a bb ′ cross-sectional view of FIG. FIG.7 (c) is cc 'sectional drawing of FIG.

  In FIG. 7A to FIG. 7C, the lower surface of the pillar 102 enters the groove 209. The pillar 102 is regulated on the left and right by the guide 210 and the flange surface 220.

  FIG. 7B shows a portion of the fitting convex portion 105. The left and right sides of the fitting convex portion 105 are also restricted by the flange surface 220 and the guide 210. Furthermore, the vertical direction is also regulated by the guide 210.

  In FIG. 7C, it is a part of the fitting recess 202. This portion is a portion after the fitting convex portion 105 is inserted and then the fitting convex portion 105 is moved to the state of FIG. 7B. Therefore, a gap is formed between the pillar 102 and the guide 210. However, the recessed portion 202 is a small area in the guide 210 and there is no problem in holding the pillar 102.

(Key part)
FIG. 8 is a diagram for explaining the structure of the key unit 104. FIG. 8A shows a state in which the pillar 102 and the flange 101 are aligned with the flange surface in the vertical direction. Then, the key part 104 moves by rotating relatively in the circumferential direction, and the state shown in FIG.

  In FIG. 8A, the key unit 104 is located on the key holding unit 201. The key unit 104 is fixed to the rail 301 by a key support 305. The end of the key part 104 is also fixed to the pillar 102. The key release unit 204 is adjacent to the key holding unit 201.

  In FIG. 8B, the key unit 104 is located on the key release unit 204. At this time, the movement of the key unit 104 in the left direction is restricted due to the relationship with the key holding unit 201. On the other hand, rightward, as shown in FIG. As a result, the horizontal direction is restricted.

  The key portion 104 is fixed to the rail 301 on the left side by a key support 305 and is also fixed to the pillar 102 at the end of the key portion 104. The right side of the key part 104 is not fixed and can be elastically deformed up and down. As a result, the key holder 201 can be overcome when moving from FIG. 8A to FIG. 8B. Like the pendulum, the key 104 is bent.

  In order to release the lock of the key portion 104, the flange 101 and the column 102 may be relatively rotated in a state where the key release portion 204 is pushed from the outside and the tip of the key portion 104 is bent. Although the key release unit 204 and the key unit 104 are shown in FIG. 5, there are two places for one flange, and at the same time, the key release unit 204 needs to be pushed and turned.

  FIG. 9 shows the key release unit support 280. As described with reference to FIG. 8, by pushing the key release unit 204, the key unit 104 is deformed, the column 102 and the flange 101 are relatively rotated, and the reel 100 is disassembled. At this time, if the key release unit 204 is pressed too much, the key release unit 204 may be damaged. Therefore, a key release unit support 280 is provided. The key release unit support 280 is provided on the reinforcement unit 203 and is provided on the upper side of the side of the key release unit 204. When the key release unit 204 is pushed in, it comes into contact and limits the pushing amount. As a result, damage to the key release unit 204 is prevented.

(Inset and inset recess)
FIGS. 10A, 10 </ b> B, 10 </ b> C, 11 </ b> A, and 11 </ b> B are diagrams for explaining the relationship between the fitting recess 202 and the fitting protrusion 105.

  FIG. 10A shows the inset recess 202. The guide 210 has a L-shaped recess. The fitting concave portion 202 is combined with the fitting convex portion 105 provided on the column 102. FIG. 10B and FIG. 10C show the relationship between the fitting concave portion 202 and the fitting convex portion 105. In the figure, the column 102 is omitted for easy understanding. When the pillar 102 and the flange 101 are assembled, as shown in FIG. 10B, the fitting convex portion 105 is inserted into the fitting concave portion 202 from the upper portion of the fitting concave portion 202. Thereafter, the fitting convex portion 105 moves to the lower portion of the fitting concave portion 202 (in the vertical direction), and then moves to the right as shown in FIG. At this time, the column 102 and the flange 101 are relatively rotated in the circumferential direction. That is, it is rotated in a direction parallel to the flange surface. The underside of the column moves along the groove 209 in the flange.

  In FIG.10 (c), the fitting convex part 105 is controlled by the up-down direction. That is, the pillar 102 is fixed to the flange 101 in the vertical direction. At this time, it can be confirmed whether it is fixed by looking through the confirmation window 214.

  The L-shaped direction of the fitting recess 202 is opposite to the flange 101a and the flange 101b.

  FIG. 11A and FIG. 11B show the case where the fitting convex portion 105 includes two fitting convex portions 105a and the fitting convex portion 105b. That is, it is a joint portion where the pillar 102a and the pillar 102b are combined. FIG. 11 (a) corresponds to FIG. 10 (b), and FIG. 11 (b) corresponds to FIG. 10 (c).

  The two fitting projections 105a and the fitting projection 105b and the one fitting recess 202 are combined and fixed. Since these three parts have a single locking structure, for example, even if force is applied to the two parts in opposite directions, the locked state can be maintained in relation to the remaining one. That is, it is probable that the force is applied in the opposite (balanced) direction evenly for all three, so this lock structure is very stable. For example, when the shaft body and the flange are united by one fitting concave portion 202 and one fitting convex portion 105, there is a high probability that the locked state cannot be maintained due to the relationship between the two parts. On the other hand, in this application, since it is a relationship of three parts, it is easy to maintain a locked state.

  In particular, the two parts of the pillar 102 (the pillar 102a and the pillar 102b) are likely to be separated in the opposite direction by external force, while the flange 101 is independent on the top surface of the two pillars. And is not affected by the force. As a result, the probability that a force is applied in the direction in which the three parts are disassembled is small, and the structure is stable.

  Moreover, although the connection part of the pillar 102a and the pillar 102b was demonstrated in FIG. 3, since it united simply with one set of the alignment convex part 302 and the alignment recessed part 303, it is easy to assemble, but it is weak in strength. However, as described above, since the fitting convex portion 105a, the fitting convex portion 105b, and the fitting concave portion 202 are held at one point, the strength is improved.

  The fitting convex portions 105 other than the fitting convex portion 105 a and the fitting convex portion 105 b are fixed by one fitting concave portion 202. As a result, the portion where the fitting convex portion 105 fixes two and the portion where one is fixed are scattered around the flange, and the flange 101 and the column 102 can be stably fixed.

(Supporting protrusion)
FIG. 12 is a diagram illustrating the support protrusion 207, and is a cross-sectional view around the support protrusion 207 when the pillar 102 and the flange 101 are combined.

  The column 102 and the flange 101 are fixed to each other by the fitting convex portion 105 and the fitting concave portion 202 in the same manner as described in FIG.

  On the other hand, the support protrusion 207 and the rail 301 are separately fixed. The support protrusion 207 has an inclined portion above it, and when the pillar 102 and the flange 101 are combined, the support protrusion 207 is fitted using the inclination.

  On the contrary, the support protrusion 207 is also provided with a reverse inclination so that it does not come off after being assembled.

  At this time, in order to give the support protrusion 207 elasticity (deformation, bending), an opening 250 is provided at an adjacent portion thereof. The opening 250 is disposed adjacent to the support protrusion 207 corresponding to the support protrusion 207.

  In this example, the support protrusion 207 is provided on a flange at a portion where the pillar 102a and the pillar 102b are combined, and serves to prevent and protect the two pillars 102 from being disassembled. When two or more pillars are separated, it is preferable to provide support protrusions 207 on the flanges of the respective combined portions.

(assembly)
FIG. 13 is a diagram illustrating assembly of the present reel. First, as shown in FIG. 13A, the inner shaft 107 and the flange 101a are assembled. As shown in FIG. 4, the inner shaft concave portion 108a and the bearing convex portion 211a are fitted and assembled.

  Simultaneously with FIG. 13A, in FIG. 13B, the pillar 102a and the pillar 102b are combined. As described with reference to FIG. 3, assembly is performed using the mating recess 303 and the mating projection 302.

  In FIG. 13 (c), the combined pillars 102 of FIG. 13 (b) are combined around the inner shaft 107 of FIG. 13 (a). It is assembled by the mechanism shown in FIGS. The column 102 and the flange 101 are fixed so that they cannot be rotated by the key 104 by the rotation in the arrow direction.

  In FIG. 13D, after FIG. 13C, the flange 101b is fitted from above the inner shaft 107 and the column. It is assembled by the mechanism shown in FIGS.

  10 and 11, when assembled, the direction of the fitting recess 202 is reversed between the flange 101a and the flange 101b. Therefore, when the flange 101b is turned in the closing direction, the flange 101a is also turned in the closing direction. . Further, since the flange 101a and the column 102 are fixed by the key portion 104 (FIG. 8), the flange 101b is easily fitted.

  When disassembling, the procedure is the reverse of the above. However, when the flange 101 and the column 102 are rotated relatively, the key release unit 204 is pushed to deform the key unit 104 and rotate in a state where the fixation is released. There is a need.

  As described above, the display portion 221 that indicates the opening / closing direction of the flange 101a and the column 102, and the second flange plate 101b and the column 102 is in the reverse direction, and is thus easily joined and disassembled.

  As described above, assembling and disassembling do not use bolts, screws, or screw types, and therefore can be easily assembled and disassembled.

  In addition, the definition of the direction in the above is demonstrated on the basis of the flange surface 220 (FIG. 7).

  Note that the pillar 102a and the pillar 102b, and the flange 101a and the flange 101b may have the same structure. There is no mistake when assembling, and it is easy to replace when replacing due to damage. Production is also possible with a single mold, so it is inexpensive.

(Assembly jig)
In FIG. 13, the flange 101a and the flange 101b are assembled separately, but can be easily assembled and disassembled by using the following jigs.

  FIG. 14 shows a jig for assembling and disassembling the reel 100 of the invention. FIG. 14A is a cross-sectional view when the reel 100 is set on a jig. FIG. 14B is a view of the jig with the lower lid 403 as viewed from the inside, and FIG. 14C is a view of the jig with the upper lid 402 as viewed from the outside.

  The jig includes a handle 401, an upper lid 402, and a lower lid 403. The lower cover 403 in FIG. 14B is provided with a reel holding portion 406, an alignment mark 404, a protruding portion 407, and a fixing portion 405.

  A reel holding portion 406 is provided at the center of the lower lid 403, which is a recess and receives the flange 101 b portion of the reel 100. Further, there is an alignment mark 404, which is used for alignment when the reel 100 is set on a jig. In addition, a protrusion 407 is provided inside the reel holding portion 406. The projection 407 is provided at a position corresponding to the key release unit 204. When the reel 100 is set on a jig, the key release unit 204 of the flange 101b is pushed into the reel 100 to disassemble and assemble the reel 100. Make it possible. Furthermore, the fixing | fixed part 405 is provided in right and left. A jig is fixed when a person steps on it.

  An opening 408, a projection 407, a handle 401, and a reel holding unit 406 are provided on the lid 402 in FIG.

The opening 408 is used to align the upper lid 402 and the flange 101a of the reel 100 when the reel 100 is viewed using the opening.
The protrusion 407 is provided on the reel holding portion 406 on the lower surface of the upper lid 402 and is the same as described above, and pushes the key releasing portion 204 of the flange 101a.

  The handle 401 is provided on the upper surface of the upper lid 402 and relatively rotates the upper lid 402 and the lower lid 403. A person grabs the handle 401 and rotates it.

  The reel holding portion 406 is provided on the lower surface of the upper lid 402 and is the same as described above.

  When disassembling the reel 100, the flange 101 b of the reel 100 is set in the reel holder 406 of the lower lid 403. The position is aligned by aligning the alignment 404 with the mark shown on the flange. Thereafter, the upper lid 402 is positioned and set on the flange 101 a of the reel 100. The alignment is performed by looking at the flange 101a using the opening 408.

  After both lids are set, both flanges are simultaneously released from the pillar 102 by pressing the fixing portion 405 with a foot and turning the handle 401 while applying a force downward by hand.

  On the other hand, at the time of assembly, first, both flanges 101 are inserted into the pillar 102 (FIGS. 8A and 10B). The column and the flange are assembled in one direction and are not rotated. In this state, the reel 100 is set on the jig as in the disassembly. Then, as in the case of disassembly, both flanges are simultaneously fixed to the pillar 102 by pressing the fixing portion 405 with a foot and turning the handle 401 by hand while applying force downward.

  With this jig, both flanges can be disassembled and locked simultaneously.

  In the above description, the key portion 104 and the fitting convex portion 105 are provided on the pillar 102, and the key holding portion 201 and the fitting concave portion 202 are provided on the flange 101 side.

  The number in the above example is one example and is not limited.

  The reel of the present invention can be applied to various uses other than the above-described wire winding and transportation purposes.
