Description

Description: TECHNICAL FIELD The present invention relates to a horizontal band saw machine and a dual-type sawing method for a horizontal band saw machine, which are mainly used in the lumber industry to continuously carry out thin plate cutting from end pieces.

(Prior art) In the past, in the lumber industry, a horizontal band saw machine that produces timber with a certain thickness from mill ends, etc., horizontally spans the band saw between the left and right band saw wheels of the machine base, and feeds the wood with rollers from the side. It is known that the material is sent to a surface plate and sawed, and that the thickness of the sawed material is adjusted by raising or lowering a lifting platform for supporting both band saw wheels. (Japanese Examined Sho 46-
(See Japanese Patent No. 26191) (Problems to be Solved by the Invention) The conventional horizontal band saw machine described above is between the band saw and the surface plate in the material feeding path, that is, since the sawing material thickness is a constant thickness that is adjusted in advance, When the mill ends with different thicknesses are randomly supplied to the feeding path, the mill members with a sufficient thickness will be processed as the proper mill products, but if the mill mill products that are less than the standard mill products are supplied. , A part of the surface of a piece of wood is ground and cut, and it is discharged without becoming a specified product.

In addition, each time the plate thickness is changed, the lifting device that supports the saw wheel of the band saw must be frequently moved up and down by the lifting device. Then, the sawing work is temporarily stopped, the sawing ability of the material is lowered, and the supplied end materials are accumulated on the carry-in conveyor.

There were various problems such as.

The present invention has been made in order to solve the above-mentioned problems, and a plurality of rows of transfer means are provided in the material feeding path to selectively supply continuously supplied sawn wood with different plate thicknesses. The horizontal type saw saw machine and the horizontal type saw saw machine that can be smoothly distributed and grinded, and can surely prevent the steady movement of the band saw and continuously perform accurate sawing. The purpose is to provide a sawing method.

(Means for Solving Problems) The structure of the means of the present invention for solving the above-mentioned problems is as follows: an elevating table attached to a machine base via first elevating means, and an elevating table. A band saw horizontally suspended between a driving wheel and a driven wheel which are axially supported at a predetermined interval, and a first transfer means fixed to the machine base provided in a material feeding path for supplying sawdust to the band saw,
A second transfer means installed side by side with the first transfer means so as to be able to move up and down to the machine base through a second elevating means, and a sawing material provided above the first and second transfer means, respectively. A horizontal band saw machine comprising: first and second pressing means for pressing; and first and second driving means linked to the first and second transfer means, respectively.

Further, the method of the present invention is such that the elevator is mounted on the machine base via the first elevating means so as to be able to move up and down, and the drive vehicle and the driven vehicle that are axially supported by the elevator at a predetermined interval are horizontally suspended. A band saw, and a first transfer means fixed to the machine base provided in a material feeding path for supplying sawn wood to the band saw,
A second transfer means installed side by side with the first transfer means so as to be able to move up and down to the machine base through a second elevating means, and a sawing material provided above the first and second transfer means, respectively. A horizontal band saw machine comprising first and second pressing means for pressing and first and second driving means linked to the first and second transferring means, respectively, and supplied to the first and second transferring means. With respect to each of the sawn timbers obtained, the first elevating and lowering are made in a state where the upper surfaces of the first transferring means and the upper surface of the second transferring means are aligned by the elevation of the second transferring means by the second elevating means. The band saw is moved up and down by the means to carry out the primary stepping operation, whereby the sawing material on the first and second transfer means is processed to have the same thickness, and the second transfer means is moved by the second lifting means. A secondary step that is moved up and down to make it different from the sawn thickness on the first transfer means. Performs teeth, selectively performing a process to do this by lumber processed in thicknesses different the lumber on the first and second transport means.

(Operation) The present invention configured as described above has the following operations.

The sawdust is supplied to two sets of first and second transfer means arranged in parallel in the material feeding path, and both upper surfaces of the upper surface of the first transfer means and the upper surface of the second transfer means are moved by the second elevating means. In a state where the two transfer means are moved up and down to be aligned with each other, the first elevating means linked to the elevating table supporting the band saw is operated to elevate the band saw and to perform the primary step.

As a result, the sawdust supplied to the first and second transfer means is cut in two rows with the same thickness.

Further, when the second elevating means linked to the second transferring means is operated to elevate the second transferring means itself, a secondary step can be performed in which the space between the band saw and the transfer bottom of the second transferring means is adjusted. For example, the first transfer means can grind a thin plate material and the second transfer means can grind a thick plate material, and these two types of grind processing are selectively performed.
