Definitions

  • Figure l s a longitudinal cross sectional View of a feed device made in accordance with the present invention.
  • Figure 2 is a transverse cross sectional view of the apparatus shown in Figure 1;
  • Figure 3 is a diagrammatic side elevational view illustrating certain movements of the mechanism.
  • Figures 4 through 6 are front elevational views show ing certain parts in variousoperating positions
  • Figures 7 and 8 are isometric versions of parts shown in Figures l and 2.
  • the feed rolls are supported in a yieldable position that permits them to move perpendicularly and angularly relative to the surface of the work piece so as to conform to the specific shape and position of distorted work pieces as they are moved through the woodworking machine.
  • the rolls are suspended in long, vertical, telescoping spring guides that have adjustable pressure springs for independently controlling the movements of each feed roll regardless of which side is raised or lowered during use and which also includes obliquely adjusted spring systems which further resist movement of the rolls out of a normal parallel relationship with each other.
  • a feed device made in accordance with the present' invention is shown to include a vmain base or housing 40 within which the feed rolls 1, 2, 3 are supported on hollow bodies 4 and self-aligning ball bearings 5 which assure the The hollow bodies 4 are fastened in bearingflanges 6.
  • the guide tubes 7 which are connected with flange 6 are displaceably held in guide bushings 8, which Vare acted upon by compression springs 9.
  • the spring pressure is Vfurther increased by e spring members 10 that are arranged obliquely to the main spring suspensions 9'by means of transversely extending bridges 11 which'simultaneously provide seats for the vertical spring elements 7, 8, 9.
  • each ⁇ feed roll is effected by means of aY universal joint shaft 17 that extends through the hollow body 4 and is connected with the feed rolls 1, 2, 3, the drive bearings 18 being rigidly connected with the bridge 11.
  • the support 19 of the apparatus in contrast to other feed devices has no threaded spindles for securing itin the desired adjusted position.
  • the stand 19 has guide shafts 20 which are provided with lat threads so as to effect vertical adjustment of the feed device by means of hand wheels 21.
  • the apparatus is driven by a reversible pole motor 13 that has two feed speeds through conventional worm and pinion gears (not shown) and Ythrough a chain 14, chain drum 15, and sprocket wheels 16 that are connected to the universal joint shafts 17 of the feed rolls.
  • the work piece 30 is placed upon the machine work table 25. and moved toward the foremost feed ⁇ roll 1 which is raised against the action ⁇ of the vertical springs as permitted by the self-aligning bearings 5 to the position in which it assumes vthe exact inclination of the upper surface of the board 30, one end of the roll being free to be raised higher or lower than the opposite end thereof.
  • Additional yieldability to the shape of the work piece Vis provided by the oblique bridges 11 which allow ⁇ for angular movement of the feed rolls with respect to the work table.
  • the feed rolls may be moved into a tilted position by the distorted work piece by the right hand or left hand spring members 7, 8, 9 arranged independently of each other.
  • the intermediate feed roll 2 operates similarly.
  • the obliquely set bridges 11 also prevent .the work piece 30 from being thrown backwardly (i.e. to the right in Fig. 1) by the cutting tool.Y This would endanger property and might cause possible injury to workmen.
  • suiiicient force urges the work piece in the opposite or backward direction (to the right in Fig. 1)
  • the bridges 11 and the rotating feed rolls are pulled rearwardly (to the right and down) in their oblique guide 12 by the frictional engagement of the work piece with the rotating feed rolls 1 and 2.V
  • the elongated yieldable springs 9 permit a cushioning effect without any considerable increase of the supporting pressure of the feed rolls against the work piece, which, in a known manner, may be adjusted by simply tightening or loosening the springs.
  • Apparatus for feeding workpieces to woodworking feed roll and said work face support means connected to said feed roll for substantially maintaining position of said feed roll, yieldable means in said support means biasing said feed roll against said workpiece, guide means in said support means adapted to allow tilting, transverse and oblique displacement of said feed roll with respect to said work face in response to the shape and movement of said work piece, said guide means including a vertical guide,
  • Apparatus for feeding workpieces to woodworking machines and the like comprising a work face, support means, a plurality of substantially parallel rotatable feed rolls spaced opposite and in parallel relation to said work face adapted to move a work piece between said feed rolls and said work face, said support means connected to said feed rolls for substantially maintaining position of said feed rolls, said support means including first guide means adapted to allow for translatory and tilting movement of said feed rolls in a plane transverse to said work face, first resilient means in said first guide means biasing said feed rolls against said work piece, said support means further including second guide means allowing for movement of said first guide means oblique to said work face and against the direction of the feeding motion of said workpiece, second resilient means in said second guide means adapted to bias said first guide means and said feed rolls against said workpiece in a direction opposing the feeding movement of said workpiece, and means in said support means for rotating said feed rolls.
  • Apparatus for feeding workpieces as in claim 5 said means for rotating said rolls including universal joint means disposed in said feed rolls and adapted to transmit rotation to said rolls.
  • Apparatus for feeding workpieces to woodworking machines and the like comprising a work face, a rotatable feed roll spaced opposite and in parallel relation to said work face and adapted to move a workpiece between said feed roll and said work face, support means for said feed roll, guide means in said support means adapted to allow tilting, translatory-and oblique displacement of said feed roll with respect to said work face in response to the shape of said workpiece, said guide means including a vertical guide for allowing tilting and translatory movement of said roller transverse to the direction of said work face ⁇ and an oblique guideV for allowing movement of said vertical guide in an oblique-direction with respect to said work face, and means for rotating said feed roll in said support.
