This is what we are trying to achieve.

Further, the method of setting and using the auctioning device for a band saw machine according to the present invention includes a separate auctioning holder that is attached to the mounting arm of the auctioning device and positioned in the swinging direction of the saw blade. A seri device for a band saw machine, which is provided with a serpentine that forms a saw blade passage part and whose serging position can be adjusted from both sides of the saw blade passage part, is installed in advance between the band saw blade and the seri mounting arm of the band saw machine. The device is characterized in that it is set in a jig that reproduces the tip part, the auctioning position of the auctioning machine is adjusted, and then the auctioning device is attached to a mounting arm provided on the band saw machine side. The aim is to achieve the above objective.

(Example) The present invention will be explained in detail below based on the illustrated embodiment. Reference numeral 1 is a sewing device for a band saw machine according to the present invention, and this device is assembled to a band saw machine 2. First, the band saw machine 2 to which the auctioning device 1 is assembled will be explained.This machine has a spall 4 attached to the machine frame 3 so as to be able to rise and fall freely, and an upper tire 6 is rotatably mounted on a bearing 5 above the spall 4. It is supported so as to be biased upward at all times.A lower tire 7 is provided below the machine frame 3 in correspondence with the upper tire 6, and the lower tire 7 is driven, and the upper tire 6 and the lower tire An endless band saw blade 8 is suspended between the band saw N2 and the band saw N2. To describe in more detail the auctioning device 1 to be attached, the auctioning device 1 is attached to a mounting arm 10 formed to protrude from the machine frame 3 of the band saw machine 2 to near the side of the band saw blade 8. The holder 1), which is a component of the auction device 1, is attached by fitting a dovetail 13 formed at the back into a dovetail groove 12 provided at the tip of the attachment arm 10. A support portion 14 is provided at the lower end of the dovetail groove 12 so as to close the dovetail groove 12, and is configured to support the holder 1) in the auction device 1. In order to support the auctioning device 1 on the mounting arm 10, a mounting structure other than the dovetail groove 12 may be used, or other bolts may be used as long as the position is regulated at least in the swing direction of the bandsaw blade 8.・There is no problem in fixing with nuts, etc., or using locking bolts, etc. in addition to using dovetail grooves. On the opposite side of the mounting arm 10, a saw blade passage part 15 is provided in the center, and a seri holding hole 16 is opened on the side surface of the holder 1) with this saw blade passage part 15 sandwiched therebetween. It is configured to hold the parsley 17. That is, the serpentine 17 has its working ends protruded from opposite sides of the saw blade passage section 15, and is fixed at a predetermined position by being tightened with the holding bolt 18. Note that a lock nut 19 is applied to the holding bolt 18 to prevent it from loosening. Of course, regarding this auction 17,
A conventional holding method as shown in the figure may be used, or alternatively, as shown in FIG.
An appropriate mounting structure or a structure for adjusting the serging position may be adopted, such as screwing the protruding position into the holder and adjusting the protruding position, and fixing it with the lock nut 22 at that position. As a precondition for using such an auction device 1, a setting jig 25 is provided, and as shown in FIG. Further, a band saw blade reference plate 27 corresponding to the band saw blade 8 is provided in front of and opposite to the dovetail groove portion 26. The band saw blade reference plate 27 may have a thickness that is completely the same as that of the band saw blade 8, and the tip position of the seri 17 is set at a certain distance from the band saw blade 8. The molecule that takes this distance may be made thicker. Of course, if the band saw blade reference plate 27 has the same thickness as the band saw blade 8, it is more preferable to use a gauge or the like to set the gap for the allowable runout of the band saw blade 8.

The seri device for a bandsaw machine according to the present invention has the specific structure as described above, and is used as follows. First, at the beginning of use, the band saw blade 8 may be already in a suspended state between the upper tire 6 and the lower tire 7 on the band ff1N2 side. Then, the auctioning device 1 is set in the setting jig 25 in a state in which it is removed from the band saw machine 2. That is, the dovetail 13 of the holder 1) is fitted into the dovetail groove 26 of the setting jig 25.

At this time, since the bandsaw blade reference plate 27 is fitted into the saw blade passing portion 15, first loosen the holding bolt 18 of the serpentine 17 and place the seri 17 in a predetermined position with reference to the bandsaw blade reference plate 27. Set. Of course, when the band saw blade reference plate 27 is set to have a thickness equal to the thickness of the band saw blade 8 plus its allowable runout, it is necessary to extend the seri 17 to a position where it lightly touches the band saw blade reference plate 27. do. In this state, the holding bolt 18 is tightened to fix the seri 17 in the seri holding hole 16 by pressing it downward. This fixed state is maintained by further tightening the lock nut 19. In this way, in the setting jig 25, the auction 1
After setting the mounting position of 7, the holder 1) constituting the auctioning device 1 is removed from the setting jig 25 and fitted into the dovetail groove 12 of the mounting arm 10 of the bandsaw machine 2 from above. In this way, the serration 17 can be mounted on the band saw machine 2 in an optimal position for guiding the steady rest of the band saw blade 8.
