Definitions

  • Upper conveyor belts are selectively pivoted between two discrete positions in one of which the upper belt remains in4 engagement with lthe folded box until a point very close to the stacking section to retain positive control of relatively short boxes. In the other position the upper belt releases'engagement with the folded box at a point considerably to the rear of the stacking section so that the liftinlg of relatively long boxes in the stacking section will not be impeded by the horizontal conveyor means. Boxes of irregular shape at the leading edge Iare handled without skewing by placing different sections of the'upper belt in different positions.
  • the barrier in the stacking section to arrest forward movement'of the blanks is stepped in a forward direction and is provided with a transition region including Ia roller 'rotating on a horizontal axis so as to lift the leading edges of the folded boxes and in this way minimize the weight applied to folded boxes as they enter the stacking section.
  • a delivery device engages the upper end of the stack to remove a pile of boxes therefrom.
  • Such delivery'device is provided with independently adjustable stop means for a plurality of vertically movable pusher arms so thatvthe irregular shape of the folded box at the top of the stack will not prevent the delivery of a pile having a predetermined number of folded boxes therein.
  • the last few folded boxes are raised to la position at the top of the barrierby a manually operated lift means to clearthe top of the barrier means and be removed by the pusher arms.
  • the instant invention relates to paper box making machinery in general and in particular relates to an improved construction of the type of apparatus disclosed in my United States Patent 3,203,561 issued Aug. 31, 1965, and entitled, Lift Cam for Stacking Device.
  • devices of the type under consideration include feed belts 'which receive blanks issuing from a folding machine as folded tubular boxes and convey these blanks ,along a generally horizontal feed path to a point where the side edges of the blanks are engaged by lifting screws and the forward movement of the blanks is arrested by engagement of the leading edges with a vertically extending barrier positioned forward of the lifting screws.
  • the lifting screws raise the blanks above the feed path to forml .
  • a bottom fed stack and a pusher means operated in time relationship 'with the lifting screws, moves horizontally from the rear into engagement lwith the top portion "of the stack to ⁇ remove a pile containing a predetermined number of blanks.
  • the instant invention provides improved horizontal conveyor means which include upper belt sections that are selectively .adjustable so that these belt sections will n-ot cause interference with blanks after they have been engaged by the lifting screws. More particularly, in the case of relatively short blanks,
  • the upper conveyor belt means of the instant invention is selectively positionable so that it positively drives short blanks to la point very close to the lifting belts.
  • the upper feed belt means is repositioned so that it ceases to positively drive the relatively long blank prior to the time that this blank is lifted to any great extent by the lifting sorews.
  • This upper belt means is hereinafter shown as comprising two independently adjustable sections so as to facilitate the handling of die cut boxes in which one portion of the trailing edge extends considerably to the rear of another portion of the trailing edge. Under the latter circumstances the more rearwardly extending trailing edge portion is released by the upper conveyor belt means at a point considerably to the rear of the point at which the less rearwardly extending trailing edge portion of the blank is released by the upper conveyor belt means. This assures a positive conveyor movement of the blank without cocking until such time as the blank is well under the control of the lifting screws.
  • an underfed stack is formed by lifting screws positioned at the sides of the stack near the rear thereof.
  • the threads of the lifting screws separate and positively support the blanks at the rear of the stack but at the forward end of the stack the lower blanks support the upper blanks.
  • the stack becomes relatively heavy and, unless appropriate measures are taken, a considerable downward force acts upon the lo-wer blanks in the stack land may interfere with the entry of new blanks at the bottom of the stack.
  • the instant invention provides .a vertical barrier means having a forwardly stepped portion at the upper end thereof with the upper and lower portion-s of the barrier means being connected by a transition means so constructed that the bottom blanks in the stack are not required to support the Iweight of the blanks positioned at the forwardly stepped upper end of the barrier means.
  • the transition region is formed by a peripheral portion of a wheel means which is positioned and rotated so that the peripheral portion moves upwardly and forward.
  • a pusher comprised of side-by-side members which are independently adjustable to their lowermost, or stack engaging, positions.
  • the adjusting means is so constructed and positioned that it may be operated while the pusher means is in operation thereby facilitating the making of adjustments required to compensate for unpredictable variations.
  • a primary object of the instant invention is to provide a novel construction for the stacking section of box making apparatus.
  • Another object is to provide apparatus of this type having novel horizontal conveyor means.
  • Still another object is to provide apparatus of this type having novel means for limiting forward movement of the blanks.
  • a further object is to provide apparatus of this type having novel means for lifting the stack to delivery position at a time after the last blank is fed into the stacking device.
  • a still further object is to provide apparatus of this type with novel pusher means to increase accuracy of the count in piles of blanks being delivered.
  • FIGURE l is a longitudinal cross-section taken through line 1-1 of FIGURE 2 looking in the direction of arrows 1--1 and illustrating apparatus constructed in accordance with the teachings of the instant invention.
  • FIGURE 2 is a fragmentary plan view taken through line 2-2 of FIGURE 1.
  • FIGURE 3 is an enlarged fragmentary plan view showing a die cut blank at a time when its forward motion has been arrested in the stacking region.
  • FIGURE 4 is a fragmentary cross-section taken through line 4-4 of FIGURE 2 looking in direction of arrows 4-4.
  • FIGURE 5 is an enlarged fragmentary side elevation illustrating the relationship between selected elements at the front barrier.
  • FIGURE 6 is a front elevation looking in the direction of arrows 6 6 of FIGURE 1 and showing one section of the pusher means for removing piles of blanks from the stacking section.
  • FIGURE 6A is a side elevation of the pusher means looking in the direction of arrows 6A-6A of FIGURE 6.
  • the portions of the box making apparatus incorporating the novel features of the instant invention include conveyor means 11 which receives box blanks in folded tubular form from a folding machine (not shown) positioned to the left of FIGURE l.
  • Conveyor means 11 moves the blanks forward along a generally horizontal feed path and delivers these blanks to lift cam operated roller 99 and lift screws 12, 13.
  • the threads of screw means 12, 13 engage the edges of the blanks to impart upward movement to such blanks to form stack 14 which is fed from below.
  • Forward movement of the blanks is arrested by barrier means 15, shown enlarged in FIGURE 5.
  • Conveyor means 11 is, in essence, 3 pairs of continuous belt devices driven at the same speed with lower belt device and 2 belts 23 and 23a, sections 19, 23, 23a
  • Belts 21 and 2,3 are mating belts which are located on one side of the machine while belts 22 and 23a are mating belts which perform the same function as belts 21, 23 on the other side of conveyor means 11.
  • Conveyor belt means 26, positioned forward of lifting screws 12, 13, is provided with an upper generally horizontal flight positioned slightly above the upper flight of belt 19.
  • Belt means 26 consists of a plurality of narrow parallel sections all driven in a clockwise direction with respect to FIGURE 1 by pulleys and associated chain and sprocket means.
  • the front edges of blanks fed by conveyor means 11 passed lifting screws 12, 13 are initially supported by belt means 26 which guides the forward edges of the blanks to the lower end of barrier means 15.
  • slat 27 positioned just below the lower end of barrier means 15 and supports the upper tlights of belt means 26.
  • Lifting screws 12, 13 provide a positive upward movement to the blanks in stack 14 in the vicinity of the rear portion of stack 14. At the forward portion of stack 14 the leading edge of a blank newly arrived at the bottom of stack 14 forces blanks thereabove in an upward direction.
  • Hold down elements 28, 29 extending forwardly from hinge means 30 apply downward forces to stack 14 and pile 17 to prevent opening of the glue joints of the folded tubular boxes prior to setting of the glue.
  • Pusher means portion 32 of delivery means 16 periodically engages the top portion of stack 14 and moves pile 17 in a forward direction.
  • Adjustable sections of conveyor means 11 Belt 20, though not necessarily positioned on the longitudinal cent-er line of the apparatus, is nevertheless referred to as the center belt. It is noted that center belt 20 at its forward end is supported by wheel 41 mounted to shaft 42 with a considerable space existing between the forward end of belt 20 and lift screws 12, 13.
  • belt 22 is of identical size and shape and is supported by identical members so that for the sake of brevity, but without sacrificing clarity, only a description of the mounting for belt 22 will be given.
  • belt 22 is guided along a path defined by wheels 43, 44, 45.
  • the shafts to which wheels 44, 45 are mounted extend from movable frame member 46 pivotally mounted with shaft 42 as a pivot center.
  • Frame member 46 is operable from its lowered position shown in the solid line in FIGURE 4 to a raised position shown in phantom in FIGURE 4.
  • Spring 47 and stop means 48 engage frame 46 to hold the latter in its lowered and raised positions, respectively.
  • belt 22 extends forward of belt 20 (as seen in the dashed lines of FIGURE l) to a position in line with slapper bar 49 which is oscillated longitudinally with respect to the box feed path and is positioned so as to engage the trailing edges of blanks being raised by lifting screws 12, 13.
  • belt 22 extendsno further forward than belt 20.
  • the adjustments for belts 21, 22 make possible the utilization of the apparat-us illustrated for stacking both very short and very long blanks. More particularly, if frame numbers 46 were in their lowered positions of FIG- URE 4 at a time when relatively long blanks were being processed, lifting screws 12, 13 would impart a considerable amount of upward movement to a blank prior to release of such blanks by belts 21, 22 in that in the lowered position of frame number 46 belts 21, 22 extend to a position extremely close to lifting screws 12, 13. Because of this relatively short distance between belts 21, 22 and screws 12, 13 and lift imparted to the blank by screws 12, 13 cause deflection of the blank to the point where it would be damaged.
  • each of the frame members 46 must be moved toits raised position where the distance between belts 21, 22 and screws 12, 13 is relatively great so that the angle yof deflection caused by the lifting of the relatively long blank while it is still engaged by belts 21, 22 will not damage this blank.
  • conveyor means 11 will cease exerting a positive drive force in the forward direction possibly before such short blank is fully engaged by lifting screws 12, 13 and certainly before such blank is in the vicinity of barrier means 15.
  • the positive driving force by conveyor means 11 it is necessary that the positive driving force by conveyor means 11 be applied to a point very close to lifting screws 12, 13.
  • Movable belts 21, 22 are provided with independent adjustments in order to accommodate the handling of die cut blanks having trailing edges in which one side extends considerably more to the rear than the other side, such as blank 51 (FIGURE 3) with portion 51a extending considenably more to the rear than portions 51b. If both of the belts 21, 22 could only be adjusted simultaneously, the only adjustment that would not damage blank 51 would be to raise both belts 21, 22. However, if this is done a positive driving force ceases to act on portion 51b at a time considerably in advance of the time when positive a driving force ceases to operate on portion 51a :and because of this blank 51 would cock and cause the apparatus to malfunction.
  • belt 22 is adjusted to its upward position while belt 21 is in its lowered position.
  • the release of portion 51b by belt 21 occurs at approximately the same time as the release of portion 51a by belt 22 so that a positive drive exerted -uniformly on both sides of blank 51 is eifective to a point where blank 51 is well under the control of lifting screws 12, 13 and the forward movement of blank 51 is arrested by barrier 15.
  • Front barrier means 1S shown most clearly in FIG- URE S, provides a vertically extending wall with a lower portion 15a and an upper portion 15b forwardly offset from portion 15a.
  • the step between portions 15a, 15b is gradual and takes place at a transition kregion formed by a peripheral portion 62 of roller means 63 which is con- -tinuously rotated by motor 64 in the direction indicated by arrow A in YFIGURE 5 about shaft 65 as a center.
  • peripheral portion 62 provides an upwardly and forwardly sloping surface moving upwardly.
  • peripheral portion 62 is illustrated :as extending for less than 90 and that lowerportion 15a is tangent to peripheral portion 62 with the upper end to portion 15a terminating at the tangent point. While this contiguration has been found to produce superior results when folder tubular boxes of corrugated paper board are being handled, it is recognized that the angular ex- CTI 6 tent of peripheral portion :and its position relative to barrier portions 15a, 15b may be varied when handling different articles or to achieve different results in a particular area.
  • slapper bar 49 which is vibrated generally parallel to the blank feed path as indicated by line V in FIGURE 5, imparts hammerlike blows to the trailing edges of the blanks in stack 14 directed towards barrier means 15 to effect a straightening action to these blanks as fully described in my aforesaid U.S. Patent No. 3,203,561.
  • the forward surface of slapper bar 49 is provided with a forward surface having generally vertical sections 49a, 49b joined by forwardly sloping transition section 66.
  • Upper section 49b is positioned forward of lower section 49a.
  • transition section 66 essentially complements peripheral portion 62 so that as the leading edge of a blank is drawn upwardly and forwardly by peripheral portion l62 the trailing edge of this blank is in engagement with the forwardly sloping transition section 66, and that at the time that the leading edge of this blan-k engages upper section 15b the upper section -49b of slapper bar 49 will be effective to continue with the straightening action.
  • conveyor belt means 26 is comprised of a plurality of narrow belts positioned parallel to one another and spaced transversely with respect to the generally horizontal feed path for the blanks.
  • Lift means 70 includes transversely extending pivotally mounted support rod 71 to which a plurality of members 72 are mounted. Each of the members 72 is of generally U-shaped with one arm 72a considerably longer than the other arm 72b. Wheel 73 is rotatably mounted at the free end of arm 72a while the free end of arm 72b is xedly secured to rod 71. Arms 72 are transversely spaced along rod 71 so that each of the rollers 73 is positioned in alignment with a different space between the sections forming belt means 26.
  • L-shaped crank 74 is ixedly secured at one of its ends to rod 71 while the other end of crank 74 is provided with transversely extending handle 75.
  • belt means 26 When belt means 26 is not supporting any blanks the upper flight thereof is essentially aligned with the most upwardly extending points of rollers 73 in the lowered position for lift means 70, established by the engagement of crank 74 with stop 76. As a stack of blank 14 is being formed, belt means 26 begins to sag so that the front end of stack 14 is nowsupportedby rollersv73 thereby relieving belt means 26 ⁇ from supporting the weight of stack 14. y
  • cran-k 74 is manually operated in a clockwise direction about rod 71 as a center thereby raising roller 73 'to thephantom position of FIGURE 5.
  • the raised position for lift means 70 is established by engagement of arms 72 with bar 27.
  • the bottommost blank in the stack 14 is positioned with-its forward end above the upper end of upper barrier section 15b.
  • Pusher means The driving and stabilizing means 79 (FIGURE 1) for pusher means 32 forms no part of the instant invention so that a detailed description thereof will not be given herein except to note that such mechanism is described in detail in my patents hereinbefore noted.
  • pusher means 32 consists of two identical sections 32a, 32a only one of these sections is illustrated (see FIGURES 6 and 6A). Both pusher means sections 32a, 32a occupy positions in a single plane perpendicular to the blank feed path and are usually positioned on opposite sides of this feed path. As will hereinafter become apparent, the transverse positions of the pusher means sections are independently adjustable as are the lowermost positions thereof.
  • Pusher means 32a is connected to the chains 79a, 79b of driving means 79 by vertically spaced laterally extending frame rails 83a, 83h whose opposite ends are connected to different vertical tie rods ⁇ 83, 83 connected directly to link of chains 79a, 79b.
  • Vertically extending guide bar 84 is slidably mounted to rails 83a, 83h by gibs 82a, 82b, respectively.
  • Clamp means ⁇ 82C associated with gib 82b clamps vertical guide bar 84 in its adjusted position along the lengths of rails 83a, 83b.
  • adjusting rod 92 threaded at its upper end extends downward through clearance aperture 91a in block 86.
  • the lower end of rod 92 is aixed to stop plate 87 while knurled adjusting nut 93 is threadably mounted to rod 92 above block 86.
  • Rod 89 extends downward from block 86 through clearance aperture 91 in plate 87 to stabilize plate 87 against rotation as nut 93 is rotated.
  • Coiled compression spring 92a mounted to rod 92 biases plate 87 downward to its adjusted position established by the position of nut 93 along rod 92.
  • the lower end of guide bar 84 extends downwardly into the upper end of tubular pusher 85 w-hich, as seen in FIGURE 1, is the portion of pusher means section 32a which engages the rear of stack 14 to remove pile 17 therefrom.
  • Pusher 85 is biased downwardly by gravity with its downward movement being limited by ear 86 which extends laterally from pusher 85 to engage the upper surface of adjustable platelike stop member 87.
  • Wheels 98, 99 mounted to bar 84 are positioned to engage the front :and back inner surfaces, respectively, of pusher 85 and thereby reduce friction acting to impede upward move-ment of pusher 85 relative to bar 84 during delivery of pile 17 from the top of stack 14. In this connection it is noted that wheel 99 is positioned above wheel 98.
  • Pusher means section 32a is intended to be adjusted while delivery means 16 is in operation and preferably just prior to engagement of pusher 85 with the rear of stack 14.
  • the position of stop plate 87 is -adjusted vertically with respect to bar 84 and rails 83a, 83h thereby establishing the lowermost position for pusher 85.
  • This lowermost position for pusher 85 is the position it will occupy at the moment of engagement with the rear of stack 14.
  • lifting screws 12, 13 continue to raise stack 14 and in so doing the portion of stack 14 below pusher 85 causes upward movement thereof with-this -movement being permitted by the telescoping relationship of vertical guide 84 ⁇ and tubular pusher 85.
  • the position of adjusting nut 93 is such that it may be convenientljl reached by an operator so that the operator may observe the exact position of pusher 85 relative to ystack 14 at the moment of initial engagement with stack 14 and make necessary corrective adjustment of member 87 before the next cycle of pusher means 32.
