SU8944A1 - Machine with several parallel sawing tape saws - Google Patents

Description

For sawing wood along a conveyor system in the proposed machine, referring to known machine tools with several machines that serve to produce parallel cuts, band saws, envelopes, each leading pulley and two guide rollers are used to use a number of staninas with rollers fixed on them for reproducing the wood supplied to the saws by a conventional chain conveyor and the usual slides installed, for each saw one of the rollers was made with adjustable slides, which were on one side Under the influence of springs, and on the other, under the action of a set screw.

In FIG. 1 is a side view of the machine; FIG. 1 view of the machine from above; FIG. 2 is a front view of the machine with a longitudinal section of one frame; FIG. 3, 3, and 3 depict three projections of the rear sled bracket; FIG. 4, 4 and 4-two projections and a longitudinal section of the front slide; FIG. 5 and 5 are two projections of the side bracket for the front skid;

FIG. 6 depicts the middle front runner bracket; FIG. 7 and 7 show two projections of rollers for pressing the tree to the conveyor; FIG. 8 depicts a schematic side view of two envelope rollers of band saws.

The machine consists of a series of pillars, made up, each, of two parts 3 and 4 (Fig. 1 and 2), mounted on base plates 1 and 2. Parts. Beds 3 and 4 are connected at the top by crossbars 5 and 6 bearing supports 5a and 6a for driving pulleys 10; cross-bar 6 below supports 19 for two rollers 19g, made in the form of a double mandrel (Fig. 1.7,7); These rollers are designed to reproduce the wood supplied to the saws by a conventional chain conveyor 21, the bottom of which has supports 22. On the sides of the back and front parts of each frame, two slides are attached, equipped with idle rollers 15. The rollers bend around band saws 17 and 18 (Fig. 8), with the lower parts of the panels being mounted in the machine (Fig. 1)

assistance guides 20, depending on the thickness of the desired product. At the front of the bed, the carriage 12 is fitted with holes 126 (Fig 4, 4) on the rods 11 fastening the brackets 7 and 8, which, in turn, are bolted to the bed part 3. On the rods 11, on the one hand, the slide 12, springs 16 are worn, and on the other side there are bolts 13 that abut against the walls of the brackets. By turning the bolts 13 and installing the brackets, you can install the rollers on the fingers 12 of the sliders 12c, which are moved by the screws 12g and directed in parallel 12z (Figs. 4, 4, 4). The sled 14 in the rear part of the frame is fixed with brackets 9 on the wall 4a (Fig. 1, 1) and is also equipped with screws with moving sliders carrying idle rollers. With the said sawing device, the required tension adjustment is achieved with bolts 13.

The operation of the machine is that the log supplied by the conveyor is sawn with band saws, driven by pulleys 10, which are rotated by the motor. The material is fed in one direction or another according to the position of the saws being installed.

The subject of the patent.

A machine with several parallel cuts, band saws, envelopes, each leading its pulley and two guiding reversing rollers characterized by using a number of stannas made up of two parts fixed on the foundation 3 and 4 (Fig. 1 and 2) connected at the top with crossbars 5 and 6 for the leading saw of the pulleys, of which the crossbar 6 also carries the support 19 made in the form of a double wad for two rollers intended to reproduce pressure on the conventional chain conveyors supplied to the saws A rum tree, in which machine the usual slides, with a screw fixed by a screw for one of the rollers corresponding to each saw, are made adjustable on fixed rods 11 and are on one side influenced by springs 16 placed on these rods. and, on the other hand, under the action of a set screw 13 (FIG. 1).
