Description of the Invention: [Technology of the Invention] The present invention relates to the winding of a saw in a wire miner that cuts hard and brittle materials such as semiconductor materials, magnetic materials, ceramics, etc. with a saw wire. A wire reel for a line machine and a wire ore machine provided with the reel [Prior Art] It is known that such a reel for a wire machine has a specific structure as shown in FIG. In this conventional configuration, the reel 71 is detachably supported by the drive shaft 72 of the wire saw using the through bolts 73. That is, the spool 71 is formed in a cylindrical shape, and a spool main body portion 75 for winding the mine wire 74 of the line miner is formed on the outer circumference of the spool 71. At the center of the reel 71, a center hole 76 engageable with the drive shaft 72 is formed. Further, Patent Document 1 discloses a configuration as shown in Fig. 4 . That is, substantially like the configuration of Fig. 5 described above, the reel 51 is formed in a cylindrical shape, and a reel main body portion 53 for winding the mine wire 52 of the line miner is provided on the outer circumference of the reel 51. At the center of the reel 51, a center hole 55 is formed which is engageable with a line miner drive shaft 54 that is rotated by a motor (not shown). Further, in the configuration of Patent Document 1, a large-diameter hole portion 55a extending from the base end of the spool 51 to the vicinity of the tip end is formed in the center hole 55 of the spool 51. A flange 58 is formed in the center hole 55 near the front end of the spool 51. Then, the flange 58 is provided with a small diameter hole portion 55b located near the front end of the spool 51 and a push hole portion 098140293 3 201021991 55c located between the large diameter hole portion 55a and the small diameter hole portion 55b. The drive shaft 54 is provided with a large-diameter shaft portion 54a corresponding to the large-diameter hole portion 55a of the slag 55, a small-diameter shaft portion 54b that can be fitted into the small-diameter hole portion 55b, and a detachable portion. The push-out shaft portion 54c of the hole portion 55c is pushed out. The small-diameter hole portion 55b of the drive shaft 54 is formed with an external thread. Then, the center hole 55 of the spool 51 is inserted into the drive shaft 54#. By screwing the nut 57 to the external thread % from the front end side of the reel 51, the push-pull shaft portion 54c of the drive shaft 54 is crimped to the push-out hole portion of the center hole 55. [Patent Document 1] Japanese Patent Japanese Laid-Open Patent Publication No. Hei No. Hei. No. Hei. No. 3, No. 3, No. 5, the disclosure of the present invention is related to the problem of the invention. The reel of the conventional wire miner shown in Fig. 4 and Fig. 5 has the following problems: 71 is formed in a cylindrical shape. For example, when the reel main body portions 53, 75 of the reels 51, 71 are wound up by the two-dot chain line in Fig. 5, the saw wires 52, 74 are wound. By the pressure, the main body portions 53, 75 of the reel are concavely deformed toward the inner side, resulting in a poorly wound shape of the ore's lines 52, 74. Moreover, the winding shape of the right silver lines 52, 74 is so deteriorated that it is on the outer circumference. side The wound misalignment lines 52, 74 are trapped in the wrong winding portion on the inner peripheral side. In this state, the right reels 51, 71 are supported by the drive shafts 54, 72 and are started by the saw wires 52, 74. When the workpiece is machined, when the saw wires 52, 74 are wound out (rolled out), the tension of the saw wires 52, 74 will be greatly changed. Therefore, the saw wires 52, 74 will be cut, or In addition, in the configuration of Patent Document 1, the reel 51 is supported by the drive shaft 54, 098140293 201021991, and the small diameter hole portion 55b of the center hole 55 is inserted with the small drive shaft 54. In the state of the radial shaft portion 54b, since the small diameter hole portion 55b is located at the end portion of the spool 51, the spool main body portion 53 is deformed into a concave shape as shown by a chain line due to the winding pressure of the saw wire 52. Therefore, in this case, the above-described saw wire cutting or the processing precision is lowered. Further, in the configuration of Patent Document i, the winding pressure of the saw wire 52 is as shown in Fig. 4, and the center hole is The small-diameter hole portion 55b acts to reduce the force toward the reduced diameter. Therefore, it is also difficult for the reel 51 to attach and detach the drive shaft 54. The problem is that when a new wire saw 52 is wound around the spool main body portion 53 of the spool 51 by a wire winding device other than the wire saw machine, the spool is attached to the drive shaft 54 of the wire saw machine. It is difficult to join the J-hole portion 55b of the center hole 55 of the spool 51 to the small-diameter shaft portion 54b of the drive shaft 54. Further, with the operation of the line miner, the mine is taken from one reel to another. After the wire % is removed from the drive shaft 54 when the spool is wound from the drive shaft 54, it is difficult to pull out the small diameter hole portion 55b of the center hole 55 of the spool 51 from the small diameter shaft portion 54b of the hammer drive shaft 54. The present invention has been accomplished in view of the problems in the prior art. SUMMARY OF THE INVENTION A primary object of the present invention is to provide a reel for a wire miner capable of suppressing deformation caused by a winding-wound waste force, and a wire miner equipped with the reel. (Means for Solving the Problem) In order to achieve the above object, the present invention is a reel for a wire saw machine having a center hole into which a reel drive shaft can be inserted, and a cylinder for winding a mine 098140293. 201021991 on the outer peripheral surface The reel body is characterized in that a reinforcing wall that reinforces the central portion under the seal = line is provided on the inner circumference of the center hole in the center portion of the winding direction. θ state Therefore, in the present invention, since the central portion of the cylindrical reel body is permeable, the deformation of the reel can be suppressed to be small due to the pressure of the _ = pressure when the body is wound up. Therefore, it is possible to suppress the situation in which the shape of the fuse winding is deteriorated due to the deformation of the mask. In the above configuration, the connection convex portion of the connection concave portion that can be engaged with the (four) axis can be engaged at the center of the reinforcing wall. In the case of the configuration, when the mineral wire is taken up on the reel body, the pressure is not ===, and the connection portion between the connection convex portion and the coupling concave portion occurs. Therefore, in the above configuration, the connection concave portion of the connection convex portion on the drive shaft can be provided at the axial center position of the reinforcing wall. Therefore, the side surface = the concavity and convexity of the joint portion between the strong wall and the drive shaft is formed to have the same effect as described above. ^ ==明中' is characterized in that it has a first reading: a driving for rotating by a motor, a person inserting the connecting concave portion and the connecting convex portion in a center hole of the reel. In the case of the reel having the third invention, the drive shaft that is rotated by the motor is inserted into the hole 098140293 201021991 in the center of the reel, and the connecting convex portion is coupled to the coupling concave portion. . According to the present invention, it is possible to suppress deformation of the cylindrical reel body due to the winding pressure of the saw wire, and it is possible to prevent the saw wire from being cut and to improve the machining accuracy. [Embodiment] Hereinafter, an embodiment of the present invention will be described with reference to Figs. 1 to 3 .

A saw wire 14 composed of one wire is continuously wound around each of the annular grooves 12a and 12a of the processing rolls 12 and 12. Then, the processing light (1, 12, 12) is rotated forward and backward by a roller driving motor (not shown), whereby the saw wire 14 is reciprocated by the processing rolls 12 and 12, and the air is reciprocated. In this case, the movement of the saw wire 14 is staggered by the weight = the predetermined advance amount, and the movement amount is less than the predetermined advance amount of the predetermined advance amount, so that the saw green raft is in the step forward advance state as a whole. Figure 1% - 15, (4)' is provided with a slurry supply mechanism above the upper break mechanism U. Supplier: The material supply mechanism 15 processes the slurry of 12, 12, and 14 grains. Above the cutting mechanism 11, it is arranged by hard and brittle. The missing piece 16 is attached to the workpiece supporting mechanism (not shown). In other words, the sawing wire 14 is moved between the processing rolls 12 and 12, and from the slurry supply mechanism 15 toward the sawing line 14 at the same time as 098140293 201021991. The slurry is supplied upward, and the workpiece 16 is lowered toward the cutting mechanism 11 together with the workpiece supporting mechanism. By this lowering, the workpiece 16 is pressed against the wire 14 to be cut. As shown in Fig. 1, a reel mechanism 17 shown in Fig. 2 is mounted on a frame 18 (not shown) of the wire saw. The reel mechanism Π is provided with: a pair of reels 20, 20 of the outer peripheral winding wire 14, that is, a winding side reel 2 for winding the saw wire 14 (left or right in FIG. 1) The reel 20); and the take-up side reel 20 (the reel 20 on the right or left side in Fig. 1) for winding the saw wire 14. Further, the two reels 20 and 20 of the reel mechanism 17 are rotated forward and backward by a motor (not shown) that can change the rotation direction and the rotation speed, thereby winding and winding the mine wire 14 from the winding side reel 2 In the cutting mechanism 11, the whole is sequentially wound, and the processed saw wire 14 is taken up and wound around the take-up side reel 20, so that the whole is sequentially taken up. As shown in Fig. 1, in the above-described housing, a traverse mechanism (not shown) is mounted in a state in which it is adjacent to the winding side reel 20 and the winding side reel 20 of the reel mechanism 17. Assume. Then, the saw wire 14 is fed in the longitudinal direction of the reels 20 and 20 by the feeding mechanism, and the saw wire 14 from the winding side reel 20 and the winding side reel 20 is guided and wound out. The saw wire 14 wound around the side reel 20 and the take-up side reel 20 is taken up. A tension applying mechanism (not shown) is disposed between the winding mechanism 17 and the cutting mechanism. Then, the predetermined tension is applied to the saw wire 14 between the processing bars 12 and 12 by the tension applying mechanism. 098140293 8 201021991 Next, the structure of the two reels 2〇 and 2〇 of the above-described reel mechanism 17 and the supporting structure thereof will be described in detail. As shown in Fig. 2 and Fig. 3, in the frame body 18, the bearing cylinder 31 is fixed in the horizontal direction through the plurality of bolts 32. In the bearing barrel 31, the drive shaft w is rotatably supported via a plurality of bearings 34. A coupling recess 33a' is formed in the center portion of the front end of the driving sleeve, and a plurality of screw holes 33b are formed in the peripheral portion (4) of the front end. A pulley % is mounted on the base end of the drive shaft 33, and a belt member % is wound between the pulleys ❿ and the pulleys mounted on the motor shaft of the motor (not shown). Then, the drive shaft 使 is rotated by the rotation of the motor via the belt member 36 and the pulley 35. As shown in Fig. 2 and Fig. 3, the winding side reel 2 and the reel main body 37 of the winding side reel are formed of a metal such as an iron-based metal into a cylindrical shape. A wrap around the main body portion 37a for stacking the saw wire 14 in a wound state is formed on the outer circumference of the reel body 37, and a flange 37c is formed at the outer peripheral end. At the center of the reel body 37, a center hole 37b which is fitted to the bearing tube 31 on the outer circumference of the above-mentioned drive shaft 33 is formed. In the central portion of the reel body 37 in the longitudinal direction, a reinforcing wall 38 for reinforcing the central portion thereof in a closed state is formed in the center hole 37b. The reinforcing wall 38 is composed of a ring wall portion 39 integrally formed on the inner peripheral surface of the center hole 37b of the main body 37, and a connecting member 4'' in the through hole of the center portion of the fitting 39. At the center of the joint member, a joint 2 098140293 9 201021991 portion 40a is formed which is engageable with a coupling recess on the drive shaft 33. A flange portion 4b is protruded from the outer periphery of the coupling member 40, and a plurality of bolt insertion holes 4'c are formed in the flange portion 40b. The wall portion 39 in the reel body 37 is formed with a plurality of bolt insertion holes 39b corresponding to the bolt insertion holes 4'' of the coupling member 4''. Then, from the front end side of the center hole 37b of the reel body 37, the plurality of bolts 41 are screwed to the screw holes 33b' of the drive shaft 33 via the respective bolt insertion holes 40c, 39b, thereby keeping the reel body 37 relative to the drive shaft % fixed. In this state, the coupling convex portion 4A of the coupling member 40 is fitted to the coupling recess 33a of the drive shaft 33, and the spool main body 37 is integrally coupled to the drive shaft % so as to be rotatable. And 5, the unused new ore line 14 is wound around the reel 2 in a full state. Then, when the wire 14 is processed using the wire 14, the roller 20 is wound around the spool 20 while the other drive shaft 33 supports the empty spool 2 . In this state, if the wire saw machine is running, with the forward and reverse rotation of __ 33, as described above, the 'reel 20, 2G also performs the forward and reverse rotation of the saw wire 供给 at the position of the processing report 12 12 for supply, while - while feeding through the feed mechanism (not shown), repeating the winding and winding, and calling it from the side of the full reel 20 by winding a 12, 12 or the like around the empty side 0 W Glaze body. In the inner circumference of the center hole 37b, the reinforcing portion 38 is reinforced in the central portion of the center hole 37, so that the core around the mine line H' can prevent the reel body 37 from being opened. 098140293 201021991 Therefore, the present embodiment can obtain the following (1) In the wire saw reel 20, 20 of the present embodiment, a reinforcing wall 38' for reinforcing the central portion thereof in a closed state is provided on the inner circumference of the center hole 37b of the reel body 37. It is located at the central portion in the longitudinal direction of the cylindrical reel body 37. Therefore, when the saw wire 14 is wound on the winding main body portion 37a of the reel body 37, the winding pressure of the saw wire 14 is made of the reinforcing wall 38. Therefore, it is possible to prevent the possibility of concave deformation of the central portion of the winding main body portion 37a. Therefore, it is possible to prevent the winding shape of the saw wire 14 from being deteriorated due to deformation of the winding main body portion 37a of the reel main body 37. Therefore, the tension of the saw wire 14 can be suppressed from changing, and the saw wire 14 can be prevented from being cut or the machining accuracy can be lowered. (2) The reels 20 and 20 of the present embodiment are 'in the reel main body 37. The reinforcing wall 38' is formed to be engageable with the drive The connection convex portion 40a of the coupling recess 33a on the shaft 33. Therefore, when the saw wire 14 is to be wound on the winding main body portion 37a of the reel body 37, the winding pressure of the saw wire 14 is not connected. The connecting portion of the convex portion 40a and the coupling concave portion 33a exerts a strong tension. Therefore, the reel body 37 can be easily attached and detached with respect to the drive shaft 33. The reel 20 can be easily disposed. That is, by the wire mining machine Other mine wire picking means, when the new saw wire 14 is wound around the winding main body portion 37a of the winding body 37 in the winding side reel 20, and the reel 20 is slid to the drive shaft 33 of the wire saw machine 'The connection convex portion 4 〇a on the side of the reel main body 3 7 can be easily joined with respect to the coupling concave portion 098140293 11 201021991 33a on the side of the drive shaft 3 3 . Further, while the wire saw is operated, the reel is retracted from the side After the saw wire 14 is taken up by the take-up side reel 20, when the reel 20 in the winding state is detached from the drive shaft 33, it can be easily pulled out from the coupling recess 33a on the drive shaft 33 side. Connection convex portion 40a on the side of the reel body 37 (variation) In the above embodiment, the drive shaft 33 is formed with a coupling recess 33a, and the reinforcing wall 38 (connection member 40) of the spool 20 is formed with a coupling projection 4a. Here, the relationship may be reversed, and the connection convex portion 40a is formed in the drive shaft 33, and the connection concave portion is formed in the reinforcing wall 38 (the connection member 4A) of the spool 20. The material of the reel body 37 is not limited. In the iron-based metal, it is also possible to use an alloy or a alloy. In the above embodiment, the present invention is embodied in a line machine in which the drive shafts 33 of the reels 2G and 2G are oriented in the horizontal direction, but the present invention may also be The drive sleeve is embodied in a wire saw machine that is oriented in the up and down direction. In the above embodiment, the two reels 20 and 20 of the reel mechanism 17 are rotated forward and backward, and the ore line (four) is taken out from the winding side reel 2 and wound up in the cutting mechanism η. The sequence is wound out, and at the same time, the processed data line 14 is taken up and wound around the take-up side reel 2 (), so that the whole is sequentially taken up. In contrast, the present invention can also embody the tangential line 14 in a wire sawing machine in which the tangential line 14 is not subjected to the reverse movement, but is moved toward the workpiece 098140293 12 201021991.
