Description

In this device, two gear racks are used, acting through the gear wheels on the numbering wheels, one of which fixes the width of the trimmed board and the other the thickness, while pressing the paper tape to the teeth of the numbering wheels is produced by one of the said strips using a lever ratchet system.

In FIG. 1 schematically depicts a longitudinal view of this device; FIG. 2 - its transverse view.

A board of a gear rack 1 (Fig. 2) coupled to a gear wheel 2 is coupled to the board for rearranging the saw, with a gear wheel 2 on the sleeve of which is attached a numbering wheel 3 (Figs 1 and 2) with numbers on the ends of its teeth corresponding to the width of the cut the boards. A roller 4 is connected to the board by a roller, which is coupled to gear 5 mounted on the shaft b, on which the numbering wheel 7 is mounted with numbers corresponding to the thickness of the board to be passed. The protrusion 8 of the rail 4 rests against the lever 9 articulated with the lever 10 connected with the spring 11 fitted with a slider 12 supporting the gear 13, which through the wheel 14 engages the gear 15 mounted on the axis of the board leading roller. On the wheel hub 13, a fastener disc 16 equipped with fists 17, 18 and 19, of which fist 17 is intended to act through a lever system 20, 21 and 22 on a ratchet 23 connected to a drum 24 (Fig. 2), on which a paper tape 25 is worn It is moved periodically over the teeth of the numbering wheels 3 and 7 when entering the cut board into the machine. The cam 18 (FIG. 1) is intended to act through the lever system 26, 27 and 28 on the ratchet 29 connected to the lever system 30 and 31 acting on the spring pad 32, which beats the corresponding digits of numerators 3 and 7 on the paper tape 25, swiveling from the drum 33 and winding through the drum 24 onto the drum 34. The cam 19 is intended to act through the rod 35 and the lever 36 on the lever 9 in order to return it to its original position.

After the board is cut, the trimming table is retracted, the support board is retracted, which serves to relocate the saw, as a result of which the rail 1 connected to the support board will rotate the gear 2 coupled to it

together with the numbering plate 3 fixed on the last numbering board 3 for the width of the board to be cropped, and under this spring cushion 32 there will be a juratopa 3 tooth with a number corresponding to the width of the board. When the board is cut, it raises to a height corresponding to its thickness its leading roller, articulated with a toothed rack 4, which will turn the tinder 5 connected to it along with shaft b and wheel numbering meter 7, and the numerator 7 will be positioned under the spring-loaded cushion 32 with a digit corresponding to the thickness of the board. At the same time: the spike 8 of the slats 4 will turn the lever 9, which through the lever 10 moves in the direction of the arrow a spring slider 12 together with the gear wheel 13 fixed on it, which will engage the clutch with the wheel 14 by means of it will receive rotation from the gear wheels 15, roller mounted on the board driving the board. When the gear wheel 13 rotates together with the disk 16, the fist 18 fixed on the last one acts through the lever system 26, 27 and 28 and the ratchet 29 on the lever 30, which with the help of the lever 31 and the spring cushion 32 presses the periodically advanced paper flax. that 25 to teeth of numbering wheels 3 and 7; in this case, on paper will be printed impressions of the corresponding numerators. - Following this, the fist 17 acts on the lever 20 and through the arms 21, 22 and the ratchet 23 rotates the drum 24, on which the tape 25, filled with the impressions, is fed, printed from the drum 33 and wound - using the drum 24 on the drum 34. Else This fist 19 acts on the lever 36 and, by means of the pull 35, returns to the initial position the lever 9; the latter, with the aid of the lever 10, is shifted: stit in the direction of the arrow 6, the slider 12 together with the gear wheel 13, which disengages from the wheel 14, and the mechanism stops working. In this case, the spring 37 will lift the spring cushion 32, which will cease to press the paper tape.

The subject of the patent.

A device for double-edger to account for boards skipped on it, characterized by the use of a gear rack 1 board, which is attached to the saw blade 1, which supports the sawmill board in order to turn the gear-wheel 2 freely attached to the axis and the numbering wheel attached to it the ends of its teeth, corresponding to the width of the trimmed board, as well as toothed rack 4, articulated with a roller leading the board and designed, on the one hand, to rotate gear 5 and, through its shaft b, numbering wheel 7 with figures corresponding to the thickness of board, and on the other hand, to rotate the lever 9 in order to move the lever 10, and with it, and equipped with the springs 11 of the slide 12 to engage the gear 13 supported by it, through the wheel 14, with the gear wheel 15 on the drive axle a roller board, which wheel 13 carries a disc with fists 17, 18 and 19, of which fist 17 serves to act through a lever-ram system 20, 21 and 22 on a ratchet 23 associated with a drum 24 designed to wind a paper tape on it periodically over the teeth of the numbering wheels 3 and 7 when entering In the machine cut board, the cam 18 is used to rotate the ratchet 29 through the system 26, 27 and 28, in order to deflect the lever 30, acting through the lever 31 on the spring pad 32 to beat off the corresponding numerals of the numerators on the paper with the drum 33 and the drum 24 wound with the aid of the drum 24, and the fist 19 is intended to return the lever 9 to its original position by acting on it through the pull 35 and the lever 36.
