SU37400A1 - A device for recording the number of logs passed through the sawing frame, their diameter and length - Google Patents

Description

In the proposed instrument for recording the islable logs passed through the sawmill, their diameter and length, from transfer to the nursing rollers of the frame, an infinite ribbon and a shaft with a pencil that produces a dash on the tape with each pencil turning the line on the ribbon corresponds to the continuous or another unit of log length. The transfer from the support of the upper feeding roller of the frame is brought into reciprocating movement by a lever controlling the ruler with a pencil, the length of which the dashes determine the diameter of the log, and the number of dashes corresponds to the number of missed logs.

In the schematic drawing of FIG. 1 shows a side view of the device, to take into account the number of logs passed through the sawing frame, their diameter and length; FIG. 2 - top view of it.

From the gear unit to the feed rolls, the shaft / is rotated, each turn of which corresponds to one or the other unit of the log length. Worm 2 is mounted on shaft 7, which causes gear 3 to rotate. Gear 4 is mounted on the same shaft as the last shaft, and shaft 6 with drum 7 is rotated by means of gear 5. The paper ribbon 27 is wound onto the latter, unrolled from drum 8,

(542),

Through gear 9, P, the rotation of shaft 7 is transmitted to shaft 22, on which pencil 70 is placed. The support of the upper feeding roller of the frame is connected to the lever 75, which consequently reciprocates near support J4 on the bracket 75. The lever 75 controls the ruler 77 equipped with a pencil 72. To eliminate deflection of the tape 27 against JO pencils 12, a support plate 18 is mounted at the back of the tape, and to create a pressure on the tape pencils and to compensate for their wear, JO pencils and 72 are installed in bushings with springs.

During the passage through the sawing frame of the log, when one or another unit of length passes through it, shaft 7, as already indicated, makes one turn, and accordingly the pencil W, rotating with shaft 22, draws 27 dashes, the number of which will correspond to the number of units of log length. Depending on the diameter of the log, the upper feeding roller of the frame through the lever 7 moves the ruler 77, and the length of the dash reproduced by the pencil 72 will correspond to the diameter of the log. The number of last lines also determines the number of logs passed through the frame. When the frame is idled or sliding along the edge of the feed rollers, pencil 12 leaves a tape 2 / straight horizontal line.

The subject matter of the invention.

Claims (3)

1. A device for counting the number of logs passed through the sawmill frame, their diameter and length, distinguished by the use of continuous movement from the transfer to the feeding rollers of the endless belt 21 and the shaft 22 with a pencil / for reproducing one dash on each revolution of the shaft, and also reciprocating from the support of the upper feeding roller - lever 73, controlling the ruler // with a pencil / 2 for drawing dashes on the same tape 2 /, in which device, according to the number of dashes left by the pencil JO The distance between which is set corresponding to a given unit length of the log is determined by this length, the length of the dashes reproduced by pencil / 2 is measured by the diameter of the log, and by intervals between the groups of the last dashes, separated by a straight line formed by a pencil on the tape, the absence of a log in the sawmill or the sliding of the feeding rollers along it, the number of missed logs. 2. In the device according to claim 1, apply adjustable spring-loaded pencils 10 and 12 in order to create pressure on the tape 2 / and compensate for the wear of the pencil. 3. In the device according to claim 1, use the support for tape 21 plate 18 against pencils 10 and 12, c. The purpose of eliminating tape sag. to the author's certificate of K.L.
