DE1653068B - Device on veneer peeling machines to adjust the distance between pressure bar and cutter bar - Google Patents

Description

the stop attached to one of the racks 9 by rotating the segment 16 in the direction of a stop Il can be aligned. Depending on the loading of the double cylinder 17, 18, 19, the segment 16 be brought into different positions, so that the Arbsitshub of the racks according to each effective push rod 12, 13, 14 or 15 is limited.

The cylinders 17, 18, 19 and the double cylinder 18 are actuated by means of one of electronic valves controlled pressurized fluid.

l 2 a special adjustment device has been Claim: hen is designed in such a way that on the the Adjusting lever having end of the pressure beam Device on veneer peeling machines to limit the adjustment angle of the adjustment shaft setting the distance between the pressure bar 5 as a stop for a pin on the screw gear and cutter bar during operation of the fixed pin on a machine by means of helical gear teeth at both ends of the pressure bar The hollow spindle provided in front of it can be seen through a common drive, which is freely rotatable on a bushing that carries the screw-actuated adjusting means, thereby marked gearwheel, and shows that the adjusting means is set by a handwheel and by a gearwheel on its one (5 ) and an associated shaft seated screw gear is adjustable.
The invention is based on the object of creating a fil on a device of the type mentioned at the beginning, which is arranged on the cutter bar (1), the roller (7) under the pressure of the the adjustment of the pressure bar fast bar (1) supporting spring (8) rests, gebil- 15 and can be done without manual labor
This object is achieved according to the invention by a bilaterally acting cylinder (10) on the pressure bar that is provided by a cylinder (3) and a bell-shaped connected to it. on its continuous piston rod to cams, which are fastened with their profile on a racks (9) on both sides of the knife, the 20 bars arranged roller rests under the pressure of a spring supported on the knife bar in each case in the toothed wheels (S) of the adjusting means, and that on the cylinder (10) there is formed a rotatable means that can be actuated as a common drive of the Vcreinem double cylinders (18) and that a bilateral acting segment (16) is arranged on the pressure bar. which is provided in its arranged cylinder, on whose length adjustable push rods (12, 13, 14, 15) 25 continuous piston rod has teeth on both sides on its circumference, which rods are fixed by rotation, each of which read into the gears of the segment (16 ) engage in the direction of one of the adjusting means, and that a stop (11) attached to the cylinder of the toothed racks (9) can be aligned with a pivoting device which can be actuated via a double cylinder. res segment is arranged. that in their length 30 adjustable push rods on its circumference, which by rotating the segment in the direction of a stop attached to one of the racks are alignable. The provision according to the invention enables a The invention relates to a device on fur- 35 very rapid adjustment of the pressure beam and to- kidney peeling machines for setting the distance equal a quick and precise setting of the same in between pressure bar and cutter bar during several, previously defined positions, without the need for of the operation of the machine by means of the use of these operations at both ends of the pressure beam arranged, by a common- manual work is required. The device has complete drive of actuated adjustment means. 40 therhin the advantage that the adjusting means are free of When peeling veneers, there is a game in addition to the fore, whereby the exact setting of the Schiibrcgulierung the paring knife the exact position between paring knife and pressure bar un- adjustability of the pressure bar or counter knife is supported. Compared to the paring knife of great importance. An embodiment of the invention is in FIG and crucial for the quality of the cut 45 drawing and is shown in more detail below and the exact, consistent thickness of the peeled is described. Veneer. In known veneer peeling machines, the drawing shows a simplified plan view of the setting of the pressure bar by means of a thread on a veneer peeling machine. Made in spindles, not shown, which can be adjusted either independently sliding guides of the measuring bar 1 with the Mcs from one another or by means of synchronously running gears 50 scr 2, the pressure bar 3 is coupled to the pressure bar 4. During the operation of the machine by means of adjusting means of the two threaded spindles operated by a common drive, each of which engages with a common drive operated adjustment means of the two threaded spindles. with her adjustable on one by the distance DD. The adjusting means fcncle of the spindle provided thread in a nut 35 are each of a gear 5 and a datergewinde of a bell-shaped cam 6 connected to the cutter bar and connected to the bearing block and on the other end carries a profile on one on the cutter bar 1 arranged screw gear, which rests with a spring 8 supported on the adjusting net roller 7 under the pressure of a screw gear wedged onto the knife shaft. As acts. So that the counter knife can be quickly readjusted during operation 60, which is a common drive for both machines, when this known device acts on the side and is arranged on the pressure beam 3, it is provided that on 'indians 10 are provided on the continuous column of which the one end of the Adjusting shaft an adjusting lever rod attached to both sides of racks 9 is mounted freely pivotable, which are a longitudinally displaceable, each in the gears 5 of the adjusting bar has rod that do not engage with their lower end 65. On the cylinder 10, a fixed gear wheel is latched via the double action of a spring in a rotatable segment that can be actuated on the same cylinder 17, 18, 19, whereby 16 is arranged, the length-adjustable pressure door limiting the opening movement of the pressure rod 12 , 13, 14, IS on its circumference.
