RU2619297C1 - Device for edge-surface lumber production from unedged pumped ones - Google Patents

Abstract

FIELD: wood industry.

SUBSTANCE: device contains two cutting machines for the serial cutting of each edge, the feeder mechanism and vertical guides (10) to move the timber parallel to the cutting edges (11, 15). The cutting machines are made with two saws with the possibility to adjust the distance between saws (2, 4) and the vertical guides.

EFFECT: increase the volume yield of the lumber.

Description

The invention relates to the field of wood processing, in particular to the production of lumber.

A device for producing edged lumber from unedged. [Tyunina Yu.P., Rykunin S.N., Shalaev B.C. Technology of sawmill and woodworking production. Textbook for technical schools. - M .: Forest. industry, 1986. - 280 p.].

This is a device for receiving edged sawn timber from unedged, containing a feed mechanism and a trimming device - a two-saw machine. The distance between the saws located on the same shaft forms the width of the lumber. Unedged boards come to trim in random order, of various widths. To obtain the greatest useful yield, the distance between the saws is changed depending on the width of each board. The edges of such boards are parallel, because pruning is made without taking into account the run.

The disadvantage of the design of this device is the inability to obtain edged lumber from unedged with sound rot.

A device for producing edged sawn timber from unedged with rotting, containing two edging machines for sequentially trimming each edge, a feed mechanism and vertical guides for moving lumber parallel to the trimmed edges [US Pat. RF at PM No. 105854].

The disadvantage of the design of this device is the inability to obtain edged lumber from unedged with sound rot.

The objective of the invention is the provision of the possibility of obtaining edged lumber from unedged with sound rot with maximum volumetric yield by adjusting the width of the strip of cut healthy wood.

EFFECT: expansion of the raw material base of the woodworking industry through the use of wood with sound rot.

This is achieved by the fact that in the device for producing edged sawn timber from unedged sawnwood, containing two edging machines for sequentially trimming each edge, the feed mechanism and vertical guides for moving the sawn timber are parallel to the trimmed edges, the edging machines are made with two saws with the possibility of adjusting the distance between the saws and vertical guides.

The invention is illustrated by drawings.

In FIG. 1 shows a general view of the first machine in its initial position.

In FIG. 2 shows a top view of wood processing in a first two-saw machine.

In FIG. 3 shows a top view of wood processing in a second two-saw machine.

The device contains two edged two-saw machines for cutting healthy wood with circular saws sequentially from each edge.

Each of the machines (Fig. 1) contains an electric motor 1 with a circular saw 2 for trimming the oblique edge and an electric motor 3 with a circular saw 4 for sawing healthy wood. Electric motors 1 and 3 are installed on rails 5, which provide the ability to move electric motors 1 and 3 in a horizontal plane. The devices 6 mounted on the bed 7 move the motors 1 and 3 by means of a screw feed 8. The sawn timber is moved along the horizontal guides 9. Along the side vertical guides 10, the sawn timber is moved, which in turn contains viewing edges 11 and 15, strips of healthy wood 12 and 14, sound rot 13.

The second edged two-saw machine is similar in design to the first machine and is its mirror image (side vertical guides 10, which are installed on the opposite side from the horizontal guides 9).

Before processing, depending on the size of the oblique edge, the strip width of healthy wood and sound rot, the saws 2 and 4 are set so that the strip of healthy wood 10 obtained during processing has a maximum width.

After adjustment (Fig. 2), the feed mechanism (not shown conditionally) is turned on and saws 2 and 4 are cut, respectively, of the oblique edge 11 and sawing out a strip of healthy wood 12. The remaining part of the wood is transferred for processing to the second machine.

Trimming wood on this machine (Fig. 3) is performed similarly. After setting up the saws, the feed mechanism (not shown conditionally) is turned on and saws 2 and 4 are cut, respectively, of the oblique edge 15 and sawing out a strip of healthy wood 14.

This device provides the ability to obtain edged lumber with maximum volumetric output.

The device is universal. After removing the saw 4 and turning off the electric motor 3, the device allows you to receive edged lumber from unedged without sound rot.
