The invention relates to wood processing, in particular to the production of parquet boards,

The purpose of the invention is to increase productivity and improve the quality of 5 processing shields,

FIG. 1 shows a machine for processing shields around the perimeter, top view; in fig. 2 is a section A-A in FIG. 1; FIG. 3 is a section BB on U of FIG. 2; FIG. 4 is a view B of FIG. 1,

The machine for processing shields around the perimeter contains a frame 1 with longitudinal guides 2 and transverse 3, saw heads 4 and milling 5, 15 located on the left and right guides 2, Above the last mounted track 6, Between the longitudinal guides 2 a chain feed conveyor 7 is mounted with stops 8 fixed on it, a base line 9 is installed at the beginning of the longitudinal guides 2, the transverse guides 3 are fixed by means of the rollers 10 by a bracket 11 of the saw-milling support a 12, K, the bracket 11 is fixedlift cylinder 13, to which rod the platform 14 of the saw-milling support is suspended. Guides 15 are mounted on top of platform 14, two saws 16 and two milling heads 17 are mounted on bottom of platform 14. At the end of the longitudinal guides 2, on a base 1 there is a lifting cylinder 18, to the shaft of which 35 is mounted a movable table 19 with vertical guides 20, walls of the cylinder head 18 up to 25

The arms are equipped with brackets 21 with holes for the passage of vertical guides 20, the edge of a vertically movable table, oriented along the longitudinal guides, is equipped with a lug 22, and on the opposite side is fixed by means of bracket 23 a cylinder 24 of lateral pressing. A fixed supporting platform 25 is installed above the upright movable table 19. A push cylinder 26 is installed above the end of the longitudinal guides 2 in front of the vertically movable table 19, on the rod of which the pushrod 27 is hinged on the opposite side of the upright table 19 1, a cylinder 28 is fixed, on the brush of which a vertically movable spring-loaded stop 29 is mounted. After the vertically movable stop coaxially with the longitudinal guides on the bed I, the receiving inclined roller table 30 is fixed.

The machine works as follows. In the initial position of the machine (FIG. 2), the vertically movable table 19 (not shown) should be in the lower position, and the rod of the side pressure cylinder 24 (not shown) should be retracted into the cylinder. The saws 4 and 16 and the milling 5 and 17 heads, the chain feed conveyor 7 and the track clamp 6 are turned on. As the next stops 8 come to the beginning of the machine, the shield 31 is placed on the chain conveyor 7 and im

The base line 9 and the stops 8. The scissors 31, moving, enters under the guigent squeeze clamp 6, saw two parallel edges of the left and right saw heads 4, then the edges of the left and right milling heads 5 are milled chain conveyor 7 and is partially located on a vertically movable table 19, is pushed by a pushing cylinder 26 and an emphasis pusher 27 up to a vertically movable stop 29. Shield 31 presses against the clamping lug 22 by the cylinder 24 of the lateral bench. The vertically movable table 19 by means of the lifting cylinder I8 rises together with the shield 31 and presses the latter against the supporting platform 25. The stop 29 is lowered into the lower position by means of the cylinder 28. The feeding device of the saw-milling caliper 12 is turned on, which, moving, saws with the left and right saw heads 16 and mills the other two edges of the shield 31 with the left and right milling heads 17.

As soon as the milling heads 17 complete the milling of the shield 31, the table 19 is lowered, the cylinder 24 removes the lateral pressing, the pushing cylinder 26, pushes the shield 31 from the table 19 onto the inclined roller table 30, then goes to the next transport or technological equipment. During the processing of the shield 31 by the saw-mill support 12, the next shield 31 moves to the end of the feeding conveyor 7 and the latter stops the feed mill 12, having processed the shield, moves along the cross guides 3 to their end, is lifted by the lift cylinder 13 to the top its position, returns to the initial position and is lowered by the cylinder.

13 to the lower starting position. The next shield is fed by a fan) f 7n by a pushing cylinder 26 with an emphasis-pusher 27 on the table 14. The cycles are repeated in automatic mode with the exception of placing the shield on the conveyor 7 and basing it on the baseline 9.

Thus, the proposed machine allows to increase the productivity and quality of processing boards.
