<Prior art and its problems> Conventionally, in band saw machines, a serrating device has been used to prevent the swing of the band saw blade and ensure stable running of the band saw blade. As shown in FIG. 7, this conventional type has a saw blade passage part 15' formed at the tip of an arm 10' that extends from the side of the machine frame of the band saw machine to near the side of the sawing action track of the band saw blade. A warp 17' is provided so that the warp can be freely pulled out, and the mounting is performed by a holding metal fitting C tightened by a holding bolt 18'. Because of this configuration, conventionally, when adjusting the staking position of the seri 17', the band saw blade 8' is suspended from the band saw machine, and then the band saw blade 8' is adjusted to approach it appropriately. As a result, the working space became narrow, and adjustment was difficult and took a long time.As the adjustment work was also relatively troublesome, auctions were often used without making sufficient adjustments. That is, in reality, even if there was an auction, it could not fully demonstrate its function.

<Technical matters attempted to be developed> The present invention was made in view of the problems of the conventional methods, and is an attempt to develop a structure of an auction device that is easier to set and a method for setting and using the same. be.

A separate seri holder having a fitting part that can be inserted and removed almost tightly is attached in a state in which it is positioned in the swing direction of the saw blade, and the holder is formed with a saw blade passing part in the center, and this The present invention is characterized in that it is equipped with a serpentine whose serration position can be adjusted from both sides of the saw blade passage section, thereby achieving the above object.

In addition, the method of setting and using the auctioning device for a band saw machine of the present invention is to provide a bottomed fitting groove with an open top on the mounting arm of the selling device, and to fit almost tightly into the bottomed fitting groove so that it can be freely inserted and removed. A separate seri holder having fitting parts that fit together is installed in a state in which it is positioned in the swing direction of the saw blade, and the holder is provided with a saw blade passage part in the center, and a saw blade passage part on both sides with respect to the saw blade passage part. A seri device for a band saw machine, which is equipped with a seri whose seri can be pulled out from the machine, is set in advance in a jig that reproduces the band saw blade and the tip of the seri mounting arm on a band saw machine, and then the seri is pulled out. This device is characterized by adjusting the position and then fitting the device from above into a mounting arm provided on the band saw machine to attach it, thereby achieving the above object. It is something.

<Examples> The present invention will be specifically described below based on illustrated examples. Reference numeral 1 denotes a seri device for a band saw machine according to the present invention, which is assembled to a band saw machine 2. First, I will explain about the band saw machine 2 to which the auctioning device 1 is assembled.
A sub-ball 4 is attached to the sub-ball 4 so as to be freely raised and lowered, and an upper tire 6 is supported in a bearing 5 above the sub-ball 4 so as to be rotatable and always biased upward. A lower tire 7 is provided below the machine frame 3 in correspondence with the upper tire 6.
is driven, and an endless bandsaw blade 8 is suspended between the upper tire 6 and the lower tire 7. Note that this band saw machine 2 has a normal configuration, and detailed explanation will be omitted. To describe in more detail the auctioning device 1 that is attached to such a band saw machine 2, the auctioning device 1 is a mounting device that is formed to protrude from the machine frame 3 of the band saw machine 2 to near the side of the band saw blade 8. It is attached to the arm 10. That is, the holder 11, which is a component of the auction device 1, has a dovetail groove 12, which is a bottomed fitting groove with an open top, provided at the tip of the mounting arm 10, and a dovetail groove 12 formed at the rear of the holder 11. Attachment is carried out by fitting together the dovetails 13. In this way, the lower end of the dovetail groove 12, which is a bottomed fitting groove, is connected to the support portion 14, which is the bottom, so as to close the dovetail groove 12.
is provided to support the holder 11 in the auction device 1. Moreover, although the holder 11 can be inserted into and removed from the mounting arm 10 vertically due to such a fitting structure, it is mounted in a substantially tightly fitted state. In addition, the auction device 1 is attached to the mounting arm 1.
0, a mounting structure other than this dovetail groove 12 may be used, or it may be fixed with other bolts, nuts, etc., as long as the position is regulated at least in the swing direction of the bandsaw blade 8. Alternatively, in addition to applying dovetail grooves, it is also possible to use a combination of fixing with locking bolts, etc. On the opposite side of the mounting arm 10, a saw blade passing section 15 is provided in the center, and on the side of the holder 11 with this saw blade passing section 15 sandwiched therein, a seri holding hole 1 is provided.
6 is opened, and the parsley 17 is held here. 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, this auction 17 may be held down using a conventional holding method as shown in FIG. An appropriate mounting structure or a structure for adjusting the selving position may be adopted, such as providing a screw in the holder 11 so that its protruding position can be adjusted and fixing it with a lock nut 22 at that position. A setting jig 25 is provided as a prerequisite for using such an auction device 1.
As shown in the figure, it has a dovetail groove 26 that almost reproduces the shape of the tip of the mounting arm 10, and furthermore, 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 26. . The band saw blade reference plate 27 may be made to have the same thickness as 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. , it may be made thicker in advance to accommodate the spacing. 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. At the beginning of use, the band saw blade 8 may be already suspended between the upper tire 6 and the lower tire 7 on the band saw machine 2 side. Then, the auctioning device 1 is removed from the band saw machine 2 and set in the setting jig 25.
That is, the dovetail 13 of the holder 11 is fitted into the dovetail groove 26 of the setting jig 25. At this time, the band saw blade reference plate 2 is provided in the saw blade passing portion 15.
7 is designed to fit, so first loosen the holding bolt 18 of the sled 17 and set the sled 17 at a predetermined position with reference to the bandsaw blade reference plate 27. 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, tighten the holding bolt 18, and
At this time, the auctioneer 17 is pressed downward and fixed. This fixed state can be maintained by further tightening the lock nut 19. After setting the mounting position of the auctioneer 17 in the setting jig 25 in this way, the holder 11 constituting the auctioner device 1 is
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.

<<Effects of the Invention>> As described above, the present invention has a structure in which the holder 11 that supports the auctioneer in an adjustable manner is configured to be removable from the mounting arm 10, and the operating position of the auctioneer 17 can be adjusted using a separate setting jig 25. Since it is configured so that it can be preset, it will always have an accurate auction17
In addition, the setting operation and the installation itself to the band saw machine can be performed extremely easily.
