Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a saw machine using an endless track for feeding material.

[Conventional technology]

Conventionally, in a saw machine of the type that feeds material by an endless track and grinds the material with a rotating saw placed directly above the material feeding line, the material is cut along with the material on the carrier side of the endless track. Since a downward force is applied, a guide rail is provided on the stationary mounting base, and the material runs on the setting line while sliding the carrier side of the endless track on the guide rail.

[Problems to be solved by the invention]

According to the above configuration, the bottom surface of the guide rail and the back surface of the endless track are worn due to the strong downward force acting on the sliding part (the pressing force acting on the material due to the weight of the material and the cutting), and the endless track. Since the surface of the carrier side of is lowered from the setting line, it becomes impossible to grind with a rotary saw.

When it becomes impossible to grind, the operation of the saw machine is stopped, first the carrier side of the endless track is pulled up to release the engagement relationship with the guide rail, and then the endless track is pushed to the side and released from the guide rail. Remove the track, then loosen the clamp for fixing the guide rail to the mounting base, insert a thin plate between the guide rail and the mounting base so that the carrier side surface of the endless track returns to the setting line, and then , The guide rail is fixed to the mounting base by tightening the fastener, and the operation is restarted by fitting the carrier side of the endless track to the guide rail, so it takes a lot of trouble and the operation stop time between adjustments is long. As a result, there was a problem that the operating rate of the saw machine was significantly reduced.

There is also a problem that it takes time to select the thickness of the thin plate for returning the carrier side surface of the endless track to the setting line.

Therefore, the present invention is to provide a saw machine which can very easily return the carrier side surface of the endless track to the setting line.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention is directed to a saw machine which uses an endless track for feeding the material and grinds the material by a rotary saw arranged above the feeding line of the material. A pedestal that can be adjusted up and down by operating an elevating device is provided below the carrier of the endless track, and a carrier-side sliding guide rail of the endless track is provided on the upper surface of the pedestal.

[Action]

If the carrier side surface of the endless track falls from the setting line, while raising the carrier side of the endless track together with the pedestal by operating the lifting device, match the endless track carrier side surface with the setting line, and then match. Stop operation of the lifting device.

〔Example〕

An embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, A is a saw machine using an endless track 1 for feeding the material.

In the illustrated case, the endless track 1 is an endless chain 3 arranged in parallel over the front and rear sprockets 2 and a slider 5 attached to a pin 4 connecting a link of the chain 3.
And bar members 6 whose ends are fixed to the left and right sliders 5 at predetermined positions. When the material is supplied to the endless track 1, the material is sent to the rotary saw 7 as it travels and is cut. .

The carrier side of the endless track 1 is guided by the guide rail 8 so as to travel on the set line.

In the case of the guide by the guide rail 8 shown in the figure, a concave portion 9 provided along the traveling direction on the back surface of the slider 5 is fitted to the upper edge of the guide rail 8 so that lateral movement can be prevented. ing.

Further, the guide rails 8 are provided on the upper surface of a pedestal 11 which can be moved up and down by operating the lifting device 10.

In the illustrated case, the lifting device 10 includes a pedestal 13 arranged in the front-rear direction on the surface plate 12, which slides in the front-rear direction, an upper surface of the pedestal 13 and a lower surface of the receiving table 11 placed on the pedestal 13. An inclined surface portion 14 provided so as to have an upward slope in directions opposite to each other, a screw hole 15 provided on opposite end surfaces of both seats 13, and a left screw provided on both ends of the both screws 15 from the center. It is composed of a screw shaft 16 into which a right screw is screwed in, and an engaging portion 17 provided at a central portion between both ends of the screw shaft 16, and a tool is engaged with the engaging portion 17 to make the screw shaft 16 in one direction. When is rotated, while sliding both seats 13 in the approaching direction, the inclined surface 14 together with the pedestal 11 causes the endless track 1 to move.
Although the carrier side is raised, a method of rotating the eccentric body by a handle through a worm gear device (not shown) to raise and lower the pedestal may be adopted.

In the figure, 18 is a connecting member that fixes the ends to the ends of both pedestals 11 and maintains the facing distance between both pedestals 11, 19 is the pedestal 11 and the seat on the surface plate 12.
Tightening bolts for fixing 13 and 13, 20 is a long hole for penetration of the bolt 19.

With the above structure, when the carrier-side surface of the endless track 1 is lowered from the setting line due to the abrasion of the back surface of the endless track 1 and the bottom surface of the guide rail 8, the carrier of the endless track 1 together with the pedestal 11 is operated by operating the elevating device 10. While raising the side, return the carrier side surface of the endless track 1 to the setting line.

〔effect〕

Since the present invention is configured as described above, when the carrier side surface of the endless track is lowered from the setting line due to wear of the contact surface between the endless track and the guide rail, the pedestal having the guide rail by operating the lifting device. At the same time, the carrier side of the endless track can be raised, and the carrier side surface of the endless track can be returned to the setting line extremely easily and quickly.

Therefore, the operation stop time of the saw machine due to the adjustment can be significantly shortened.
