In order to stop by hitting the positioning stopper 94, the carriage 3 is guided to an appropriate position where the work is easy with respect to the pair of bearing

units

64 and 65 and stopped.

Here, the operator pushes the suspended processing roller 9 in the horizontal direction, guides the processing roller 9 being held between the bearing

units

64 and 65, and makes their axes substantially coincide. At this time, since the processing roller 9 is suspended by the processing roller holder 10, it can be easily guided to the coincidence position of the shaft centers by applying a force from the horizontal direction.

When the floor surface of the wire saw is inclined due to the setting of a draining slope, the carriage 3 does not stand upright in the vertical direction, but the processing roller 9 is suspended from the center of gravity by the processing roller holder 10, that is, the gravity Because it is in the direction of action, it hardly tilts.

Next, the operator turns the lateral movement handle 78 in a predetermined direction, and moves the lateral movement portion 5 in the lateral direction, that is, the horizontal direction by the screw action of the lateral feed screw shaft 29 and the lateral feed nut 30. As shown by the arrow b, the processing roller 9 is moved horizontally in the direction of the central axis, so that the tapered hole 66 at one end of the processing roller 9 is fitted into the tapered shaft 67 of the bearing unit 64 facing each other.

Subsequently, the operator moves the quill-shaped bearing unit 65 in the direction in which the processing roller 9 is sandwiched, that is, in the direction of the arrow c, and fits the tapered shaft 68 of the bearing unit 65 into the tapered hole 66 of the other boss. As a result, the processing roller 9 is sandwiched between the pair of bearing

units

64 and 65 in a centered state by fitting the tapered portions.

As described above, when the processing roller 9 is assembled to the pair of bearing

units

64 and 65, the processing roller 9 is positioned in the horizontal direction by the lateral movement function by the lateral movement drive device 28 attached to the lateral movement unit 5. It is easy and efficient. The amount of movement in the horizontal direction at this time can read the position of the movement indicator 90 from the movement scale plate 91.

Finally, the operator inserts the fixing bolt 70 into the shaft hole 69 at the center of the quill-shaped bearing unit 65 and the center hole 9a of the processing roller 9 as indicated by an arrow d, and inserts the male screw at the tip of the fixing bolt 70. The processing roller 9 is screwed into the female screw 71 of the bearing unit 64 and firmly fixed between the pair of bearing

units

64 and 65 to be fixed. In this way, the plurality of processing rollers 9 are attached between the two bearing

units

64 and 65, and are driven by these bearing

units

64 and 65 so that they can be rotated together and incorporated into the wire saw.

When removing the processing roller 9 from the pair of bearing

units

64 and 65 of the wire saw, the operation opposite to the above operation may be performed. When the processing roller 9 has been assembled and removed, the operator returns the processing roller holder 10 from the wire saw lifter 1 to the stand 59 of the storage cart 58.

Next, the wire saw lifter 1 can be used for conveying the workpiece 12 and supplying and taking out the workpiece 12 from the wire saw by mounting the workpiece holder 11 instead of the processing roller holder 10. As shown in FIG. 18, the work holder 11 is placed on the stand 62 of the storage carriage 61 and its receiving arm 62b, and is locked to the detachment prevention hook 62a.

Accordingly, the operator moves the wire saw lifter 1 of FIGS. 1 to 4 to the vicinity of the storage cart 61 of FIG. 18 and correctly faces the wire saw lifter 1 to the work holder 12 as shown in FIGS. 18 and 19. . In this process, the positioning guide roller 57 is guided by the positioning guide 63 and faces the work holder 12 in a positioned state. Further, the stop position of the wire saw lifter 1 at this time becomes a predetermined position by contact of a part of the carriage 3 of the wire saw lifter 1 with the stopper 93.

Here, the operator operates the elevating drive device 23 to raise the second hook 8, hang the second hook shaft 19 of the work holder 11 on the second hook 8, and place the work holder 11 on the wire saw lifter 1. Installing.

In this mounted state, the workpiece 12 can be transported by the wire saw lifter 1, and the workpiece 12 can be supplied to and removed from the wire saw. Therefore, the operator faces the workpiece 12 that is to transport the workpiece holder 11 by moving the carriage 3. After that, the work holder 11 is adjusted to the receiving height of the work 12, the slider handle 45 is held, the fork 22 is advanced, and it is inserted into a fork insertion hole (space) (not shown) of a member fixed to the work 12. Then, the workpiece 12 is picked up by the fork 22 by the ascending / descending portion 4 and transported to the wire saw, and the workpiece 12 is supplied in a horizontal posture to the processing position of the wire saw and transferred to a workpiece support device (not shown) of the wire saw. In this way, the workpiece 12 is in a state where it can be cut at the processing position of the wire saw.

When supplying the work 12 to the wire saw, if the floor surface of the wire saw is inclined such as a draining gradient, the support 2 of the lifter 1 for the wire saw does not stand upright but is inclined. When the tilted workpiece 12 needs to be corrected, the operator turns the leveling handle 84 to rotate the leveling feed screw shaft 33 in the tilt correction direction, and moves the leveling feed nut 35. The leveling portion 6 is swung around the support shaft 32, the inclination of the fork 22 is corrected together with the work holder 11, and the work 12 can be supplied in a horizontal posture to the processing position of the wire saw.

When the inclination state is corrected, the inclination direction of the workpiece 12 can be determined from the relative position between the angle indicator 88 and the angle scale plate 89, and the inclination angle at that time is the angle indicated by the angle indicator 88. It is known by reading from the scale on the scale plate 89. The angle indicator 88 and the angle scale plate 89 can also be configured by a commercially available simple level.

The present invention can be used not only for carrying in and carrying the processing roller 9 and the workpiece 12, but also for carrying in and carrying tools and parts necessary for the operation, maintenance and inspection of the wire saw.
