SU79868A1 - Installation for sawing balancing saw logs on circles - Google Patents

Description

The object of the invention is a machine for cutting logs into circles, consisting of a circular saw with balance bar and a carriage for feeding logs to the saw.

A feature of the installation is that in it, to automate the supply of logs, a carriage is used that is brought into reciprocating motion by means of a ratchet connected with a balapsier saw.

The device (see drawing) has a frame consisting of two wooden runners 1 fastened with two transverse wooden bars 2. On one of the transverse bars there is a roller conveyor consisting of four rollers 3 with a grooved surface. The rollers are interconnected by endless 4-chain link-chain chains.

Chains 4 are driven in a discontinuous motion by a linear storage mechanism consisting of a body, which is a truncated trihedral prism. On both sides of the body are six dogs, three dogs on each side. In order to more accurately feed the logs, the intervals between the dogs are consistently reduced. Each of the dogs has an offset to the rollers of the chains. The pawl is fastened on the body with the help of fingers. The displacement of each finger by 3.3 mm (iri chain pitch of 20 mm) provides iodachi of a conveyor belt of 70 mm pa (with fluctuations in either direction by 3.3 mm). The stroke of the dogs is limited by the stops against which the dogs are pressed with the pins.

Lipey ratchet moves along a guide.

At one end of the ratchet mechanism there is a window that serves to connect the ratchet mech-off mechanism with the end of the two-shoulder feed lever, whose shoulders are located at an angle of 80 °. Connect the other end of the lever with the slider through the okpo. There are two cams on the slider for moving the ratchet mechanism, which are driven in engine 79868

The movement from the fork located at the lower end of the balance bar 5. The rolling movement of the balance bar 5 is performed on gears and an eccentric mechanism 6, the connecting rod of which is attached to the frame 7.

The gearbox consists of a screw, mounted on the saw shaft 8, and ring gear, planted on the transfer roller. At the other end of the roller there is an asterisk, which chains the second gearbox in motion. Oi transmits rotation through the crown gear to the eccentric 6.

On the balance bar 5 on the slide 9, install an electromotor which, through the pinion gear 10, rotates the sowing shaft 8 located at the lower end of the balance bar 5.

Balancer 5 is suspended on ball bearings 11 and 12, which are mounted on a frame arc. The arc of the frame is made of channel bar and bolted to the skid m 1.

The saw shaft 8 rests on two ball bearings 13.

Pilia head consists of two couplings (fixed 14 and removable 15) and a saw blade 16.
