The invention relates to the timber and woodworking industry and can be used in cutting installations with longitudinal feed of logs.

A device for measuring the lengths of assortments is known, comprising a V-shaped receiving table rotatable around a longitudinal axis with a drive for its rotation and pivoting stops mounted along the receiving table with individual electric drives for their rotation Cl.

It is also known a device for measuring the lengths of assortments containing a V-shaped receiving table with a rotary drive rotating around a longitudinal axis, a longitudinal rod mounted near the receiving table with stops rotating in the transverse vertical plane and electromagnetic locks of the upper position of the stops f2. .

The disadvantage of these devices is the design complexity.

The purpose of the invention is to simplify the design.

This goal is achieved by the fact that the side of the receiving table adjacent to the longitudinal side has supporting elements for interacting with pivoting stops, and the axis of rotation of the V-shaped P13 table is offset along the width of the receiving table relative to its supporting elements.

FIG. 1 shows the device, front view; in fig. 2 - the same, top view of the device; in fig. 3-section A-A in FIG. one.

The device includes a mechanism for feeding the logs, a beam 2 mounted on supports 3 on the side of the V-shaped receiving table; 4, along its longitudinal axis. The rotation of the receiving table 4 is carried out by its drive made in the form of a power hydraulic cylinder 5.

On the beam 2, a longitudinal traction ha is installed, made in the form of three stub-piston sleeves 6 connected in series with each other 6 shafts 7 installed in sliding supports 8. The shafts 7 are connected to the stem of a hydraulic damping device 9.

On the shafts .7, in accordance with the length of the sawn timber, set the pivot stops 10, equipped with rubber pads 11 to soften the impact and / reduce noise. In a vertical position, the lugs 10 are supported by electro-magnetic locking devices 12.

On the beam 2 fixed photocell 13 and the limit switch 14 of the actuator

feed mechanism. Limit switches 15 and 16 of the receiving table 4 are fixed on support 3. The cam 17, which interacts with the switch 14, is fixed on the shaft 7, and the cam 18,

interacting with switches 15 and 16, fixed on the receiving table 4.

On the beam 19, mounted on the supports 20, fixed illuminators 21

0 photo relay 13, and supporting elements 22 for engagement with the stops are installed on the adjacent side of the receiving table with the longitudinal side.

The device works as follows.

In the initial position, the stops are 10 lifts. The operator from the console sets the length of the sawn assortment, One. Electromagnetic lock 12 is temporarily turned on, keeping the stop 10 in the upper position and photo relay 13 with the lighter 21 of the pre-stop of the switch. When triggered electromagnetic lock 12 stop

10 is moved to a horizontal position by its own weight.

A whip moving at high speed overlaps the light beam. Electric signal with photorelay, 13 gives the command to switch the mechanism

1 feed at reduced speed.

With this speed, the whip acts on the support 10, driving the shafts 7, on which the cam is fixed

5 17, acting on the limit switch 14, the electrical signal from the limit switch 14 gives a command to stop, the feed mechanism 1 and the cutting apparatus is pulled up. At the end of sawing, the receiving table 4 is lowered, the assortment is reset, and at the same time the stop 10 is raised, with which the supporting element 22 interacts.

c. In the lower position of the receiving table 4, the cam 18 acts on the switch 15, giving a command to reverse the movement of the hydraulic cylinder. p. 5.

P The return of the shafts 7 to the initial position occurs through the action of a hydraulic damping device 9.

When the receiving table is returned to the 4th initial position, the work cycle is repeated. The signal about the initial position of the receiving table 4 is given by the switch 16 when the cam 18 is applied. In comparison with the known ones, this device has a simpler design due to the fact that the table is raised and lowered and the stops are raised by the same drive.
