Definitions

  • This invention relates to apparatus for uniformly orienting mitered-end cleats and feeding them to the conveyor bands of a box-part-making machine.
  • Wirebound box and crate blanks are usually formed by cleats and side material or slats stapled together to forni a plurality, usually four, box sections or sides which are secured together by binding Wires stapled to the box sections.
  • the cleats are often provided with ncitered ends so that when the box blanlr is folded around to set up the box, the abutting ends of the cleats at each corner of the bon will rit snugly together to lend strength and rigidity to the box.
  • Wirebound boxes of this general type are disclosed in U. S, Patent No. 1,933,030, issued October 3l, 1933.
  • cleats and side material or slats are conveyed past a transverse row of stap-ling units where staples are driven astride binding wires and into the side material and cleats to form the wrebound box or crate blanks.
  • the cleats and slats are conveyed through the machine by means of two or more conveyor bands on which are secured spacer blocks having projecting push-elements which engagethe slats and the cleats and convey them in properly assembled relationship.
  • This apparatus includes a hopper in which a generally vertical stackv of cleats is held in position above each of the conveyor bands, with the bottom cleat or the stack in the path ci the cleat-pushing elements on the spacer blocks so that the elements will engage and the cleats individually and successively from the bottom of the stack.
  • rlhis apparatus enables a considerable saving of time effort on the part of the personnel employed in placing the box materials on the conveyor bands of the machine.
  • the apparatus disclosed necessitates prearrangement ci the cleats to there uniform orientation.
  • the apparatus of the invention includes a cleat hopp-er in which the cleats are stacked generally parallel to each other but without regard to orientation.
  • a pickup conveyor is movable across the bottom of the hopper to remove cleats from the hopper and convey them single le along a path generally lateral to the cleats.
  • the cleats are carried against the periphery of a pair of rotatable spacing wheels having peripherally spaced elements for engaging the cleats and removing them individually and at timed intervals from the pickup conveyor. This results in spacing the cleats apart so that there is sufficient room to permit axial rotation of the cleats to achieve uniform orientation.
  • the spacing wheels deliver the cleats to a pair of cleat orienting belts which are spaced apart a distance approximately equal to the length or" the cleats and are arranged to convey the cleats along a path generally perpendicular to the long axes of the cleats by engagement of the orient-- ing belts with the ends of the cleats.
  • the orienting belts are inclined so as to present to the end of the cleats surfaces inclined upwardly and outwardly so that the cleats in a short-side-up position ride on the orienting belts at a higher level than the cleats in a short-side-down position.
  • a pair of cleat turning members or pawls are mounted above the cleat orienting belts in position to engage and impede forward movement of the upper portions or the cleats riding on the orienting belts in a short-side-up position, but not to engage the cleats riding in a short-sidedown position.
  • These cleat turning members acting in conjunction with irictional engagement of the lower corners of the cleats with the moving orienting belts, create a couple which rotates the cleats and causes them to fall to a short-sidedovvn position.
  • a pair of leaf springs is mounted adjacent the cleat turning members in position to engage and bear downwardly upon the trailing portion of the upwardly racing short side oi each of the cleats in a short-side-up position on the orienting belts, to enhance this rotative couple.
  • spacing wheels In order to disene'age the drive to the pickup conveyor, spacing wheels cleat orienting belts when a solid line of cleats of predetermined extent has accumulated on the stacking conveyor, a pair of photoelectric cells are positioned at spaced points along the path of the cleats on the stacking conveyor and a pair of light sources are arranged in line with the photoelectric cells n the opposite side of the cleat path.
  • These photoelectric cells are connected to an electrically controlled clutch and brake in the drive to the pickup conveyor, spacing wheels and cleat orienting belts in such manner that when the beams of light to both of the photoelectric cells have been intercepted by cleats on the stacking conveyor, the clutch is disengaged and the brake is applied to stop the drive to these units until suicient cleats have been removed to expose both light sources.
  • FIG. 1 is a somewhat diagrammatic side elevational view of a dispensingr apparatus embodying features of the invention, the apparatus being shown partly in section;
  • FIG. 2 is a somewhat diagrammatic top plan view of the machine
  • Figure 3 is a fragmentary vertical section, at enlarged scale, taken generally along the line 3 3 of Figure 1;
  • Figures Il, 5 and 6 are diagrammatic views of one of the cleat-turning assemblies of the apparatus showing, in successive steps, the turning of a cleat by said assembly;
  • Figure '7 is a schematic diagram of the electrical circuit which controls the drive of the apparatus.
  • the cleat orienting and feeding apparatus is shown positioned alongside one of the conveyor bands I (at the extreme right in those iigures) near the input end of the box-part-making machine.
  • the various component mechanisms of the apparatus are supported on a framework which includes a plurality of upright members i2. with appropriate longitudinal and transverse bracing members, mounting brackets and bearings for the various components oi the apparatus.
  • rlhe apparatus includes a large hopper M, shown at the extreme left in Figure 1, which is adapted to receive a plurality of cleats i3 arranged generally parallel to each other but without regard to orientation.
  • the hopper It is open at its lower end and a pair of pickup conveyor belts i5 are arranged to extend across the bottom of the hopper along a line generally perpendicular to the long axes of the cleats in the hopper.
  • the pickup conveyor belts IS are trained upon idler pulleys i3 and drive pulleys IS, the latter being driven from a motor 28, suitably supported near the door beneath the center of the apparatus.
  • the drive from the motor 23 to the pulleys Ii is through a pulley 2! ( Figure 1) on the motor shaft, a V-belt 22, and a pulley 23 ( Figure 2) xeol near one end of a sleeve 2t rotatably supported on a fixed shaft 25 Which is supported at either end by brackets 3l on a cross-beam 3?. of the frame oi the apparatus.
  • One plate of a solenoid-controlled clutch ZB is fixed on the other end of the sleeve 2t, and the other plate o the clutch 25 is fixed at one end of a second sleeve 28 also rotatably mounted on the ixcd shaft 25.
  • a sprocket 29 on the sleeve 23 has trained about it a chain Sii which is also trained about a sprocket 32 secured on the same sha-it on which the pulleys iii are fixed.
  • a solenoidcontrolled brake 2l Arranged to act upon the opposite end of the sleeve 23 is a solenoidcontrolled brake 2l, which is operable, in combination with the clutch 2G, to control the drive train just referred to, as will be more particularly described hereinafter.
  • the pickup conveyor belts it are thus driven across the bottom of the hopper ifi in the direction indicated by the arrow A in Figure 1, and tend to move the cleats out oi the hopper in that direction.
  • the lower end Ida of the wall of the hopper Ul toward which the pickup conveyor belts it tend to move the cleats out oi the hopper is spaced above the pickup conveyor belts i6 by a distance slightly exceeding the thickness oi the cleats so as to permit the cleats to move from the hopper only single nie on the conveyor belts it.
  • a pair of spacing wheels 3S are positioned across the output or right-hand end oi the pickup conveyor belts i5, as viewed in Figures l and 2, so that the belts i3 carry the cleats laterally against the periphery or" the spacing wheels 35.
  • rEhe spacing wheels 35 are secured to a rotatable shaft B which is driven in the direction indicated by the arrow B in Figure 1, by means oi a sprocket which is coupled through a chain 62 to a sprocket lil ( Figure 2) xed on the driven shaft 36% previously referred to.
  • each of the spacing wheels 35 are provided. a plurality of equally spaced, radially projecting cleat-engaging elements Eta adapted to engage the cleats on the pickup conveyor belts it and lift them from the belts and over the tops of the spacing wheels
  • the drive ratio of the pickup conveyor belts it and spacing Wheels 36 is such that the pickup conveyor belts i@ will furnish cleats to the spacing wheels 36 at a rate faster than the rate at which the spacing wheels remove cleats from pickup conveyor belts. This causes cleats to ccumulate on the pickup conveyor belts IE, as shown in Figures l and :2.
  • the cleats will be moved :forward intermittently, being stationary except when the cleat engaging elements @63a on the spacing wheels t6 remove a cleat from the output end of the pickup conveyor belts IE, at which time the line of cleats on the pickup conveyor belt will move forward a distance equal to the thickness of one cleat to fill the space vacated by the cleat removed and place the next cleat in position to be picked up by the next succeeding pair of elements @ila on the spacing wheels 3E.
  • 36 are mounted at the output or right-hand end of the spacing wheels 36, as viewed in Figures l and 2, to receive the Vcleats from the spacing wheels 36.
  • the left-hand ends of the slide rails 4B are ele.- vated above their right-hand ends and are positioned so as to intersect the peripheral line of the spacing wheels at a point just to the right of the tops of the spacing wheels, so that as the cleats pass over the tops of the spacing wheels fit they are picked up by the slide rails l5 and slide down them onto a pair of orienting belts 48.
  • the function of the foregoing mechanism is thus to supply cleats to the cleat orienting belts til at spaced intervals. This prevents the accumulation of a solid line of cleats on the cleat orienting belts and allows room for rotating the cleats to achieve uniform orientation.
  • the orienting belts 43 are spaced apart a dis. tance approximately equal to the length of the cleats and are adapted to convey the cleats along a path generally perpendicular to the long axes of the cleats by frictional engagement ⁇ with the ends of the cleats.
  • the orienting belts are trained upon idler pulleys t, which are mounted on short, rotatable shafts 52, and about vdrive pulleys 54, which are secured'to short, rotatable drive shafts 5b (see also Figure 3).
  • the axes of the shafts 52 and 5b are at 45 angles with respect to the horizontal (as best shown in Figure 3) so that the pulleys 5@ and 54 and orienting belts 43 are inclined to present to the ends of the cleats surfaces inclined upwardly and outwardly; thus, the cleats which fall on the belts in a short-sideup position (as shown in broken lines in Figure 3) ride at a higher level than the cleats which fall onto the belts in a short-side-down position (as shown in full lines). Because of the shape oi the ends of the cleats, and of the inclination of the orienting belts 48, the cleats fall to either one or the other of these two positions.
  • the drive shafts for the cleat orienting belts it are rotatably supported in bearings 5'. ( Figure 3) mounted on brackets El! secured to upper ends of two of the upright members l2.
  • the shafts 55 are driven through bevel gears 59 and (it, the latter being secured at opposite ends of a short, horizontal drive shaft iii. rotatably supported in bearings @d on a base ii secured on a cross-brace lil' of the frame of the apparatus.
  • the drive shaft 52 has keyed thereon a spur gear @c which meshes with a spur gear 'Hi ( Figure 2) on a shaft 12 which extends transversely of the apparatus and is rotatably supported at its opposite ends in bearings 'Ni ( Figure 2)
  • the latter shaft 'i2 has keyed thereon a sprocket 76 about which is trained a chain "i3 which is also trained about a sprocket ils on the driven shaft 33 previously referred to.
  • rihe rotatably mounted pawls 82 are normally urged by their own weight in a clockwise direction about the shaft 84, as viewed in Figures a, 5 and 6. This movement is limited by means of stop fingers 8S which extend beneath the pawls i2 and are adjustably secured on transverse shaft by means of collars 9!! ( Figure 2)..
  • rlhe co1- lars Sii and stop fingers 88 are so positioned that the stop iingers cause the cleat turning members or pawls 82 to .assume a normal position wherein their lower -ends 82a are at such level as to engage the upper portions of the cleats riding on the orienting belts 84 in Va short-side-upposition, but not the cleats in a short-side-down positiOn.
  • a cleat i3 in a short-side-up position, is shown as it iirst engages vone of the pawls 82.
  • the forward movement of the upper portion of the cleat is impeded by the pawl 32, while the lower portion of the cleat tends to move in the direction of the arrow C, due to frictional engagement between the lower corners of the cleat and the moving beltsffit.
  • This rotative couple is enhanced by means of leaf springs 5:!
  • the rotatable mounting of the pawis t?. permits the pawls to move upward yieldingly, as shown in ⁇ Figures 5 and 6, to permit the cleats to pass between the pawls 32 and the orienting belts d8, while the cleats are rotating.
  • the action of the pawls 82 is only such as to rotate the cleats through an angle of approximately or slightly more; however, the cleats will ride only in either a short-side-up or a short-side-down position and since the cleats halfway between these two positions are urged i Y gravity toward a -short-side-down position and since the pawls have initiated rotation of the cleats to a short-sidepown position and continue to engage the cleats to prevent a reversal of this rotation, all of the cleats fall to a short-sidedown position.
  • the eifect of the orienting elements just described is thus to position all of the cleats with their short sides down. This is the orientation in which it is desired to feed the cleats into the hopper Sii (at the extreme right in Figure l), in which they are held in position above the conveyor bands It of the box-parteinalring machine for successive removal by the cleat-pushing elements Qta projecting from spacer blocks 9:3 clamped on the conveyor bands i5.
  • Adjacent the output end of the orienting belts i8 are a pair of stacking conveyor belts it@ which are arranged to receive cleats from the orienting belts 45 and to convey the cleats along a path generally lateral to the cleats by fric-tional engagement of the belts with the bottoni surfaces of the cleats.
  • the transfer of cleats from the orienting belts iii to the stacking conveyor is accomplished without rotation of the cleats from their short-side-down position.
  • the stacf'ng conveyor belts I til are spaced apart a distan e less than the length of the short sides of the cleats and all of the cleats are thus supported at the same level on the steel-:ing conveyor belts.
  • the stacking conveyor belts are trained about drive pulleys to2 and large idler pulleys i.
  • the drive pulleys EQ2 are driven directly from the motor 2e through a sprocket its on the sleeve 22 ( Figure 2), a chain ISS and a sprocket Idil on the same shaft i ill on which the pulleys i are lined.

  • 25 are so positioned that the beams of light are directed through the path of the cleats at an oblique angle relative to the sides of the cleats, so that when two abutting cleats intercept one of the beams of light, no appreciable amount of light reaches the ⁇ photoclectric cell.
  • the width of each of the beams of light is greater than the effective width of a single cleat, as viewed from the oblique angle at which the beams of light intersect the cleat path, so that neither of the beams of light can be entirely extinguished by one cleat alone.
