Definitions

  • the box blanks are successively fed from the bottom of a stack by means of a suction type conveyor belt in association with a guide arm or gauge which permits only one blank at a time to pass thereunder at a controlled rate.
  • FIG. 1 is a top plan view of the feeding equipment
  • FIG. 3 is a fragmentary end view taken along line 33 of FIG. 2,
  • FIG. 4 is a view similar to FIG. 2 partly in cross section
  • FIG. 5 is a sectional view taken along line 55 of FIG. 4,
  • FIG. 9 is a side elevational view of a gauge and. stop assembly
  • a pair of racks 41 straddle the belt 34 and are secured to the frame 31, said racks being straddled by the vertical legs 42 of elongated L-shaped brackets 4-3, the horizontal legs 44 of which are secured to the frame 31.
  • the two outer guides have fins 65 secured to the outer flanges 55 thereof, said fins properly positioning the box blanks on the conveyor belt 34.
  • the intermediate guide 53 may have a central fin 65 as shown in FIG. 8, which fits into the slot 65" between adjacent flaps of the box blank.
  • the long box blank is effectively guided at three points, which will prevent skewing thereof as the box blank is deposited on conveyor belt 34.
  • a slot 91 which is vertically elongated, as shown in FIG. 9.
  • the lever also has a central aperture or bore 4 92 therethrough, which also extends through the slot 91.
  • Means are provided to pivot said lever in a counterclockwise direction about its pivot pin 84 against the tension of coil spring 88.
  • an actuator 93 is provided, preferably an air cylinder secured as by screws 94 to the plate 81.
  • the actuator 93 which is in vertical position, has a slidable piston connected to a plunger 95 that is vertically aligned with the central bore 92 in the lever 85.
  • the end of the plunger which preferably is threaded, mounts the corresponding threaded end of a fitting 96 which extends into said central bore 92, the lower end of said fitting having secured thereto a pin 97 which extends through the elongated transverse slot 91 of the lever 85.
  • Means are provided to adjust the vertical position of the belt assembly 100.
  • the vertical edges 108 of the plates have elongated slots 109 on their inner surface, which serve as guides for the lateral edges of a strip 111 which is positioned against a second strip 112, said two strips being secured to the block 74 as by screws 113.
  • a substantially rectangular plate 115 is positioned between the upper ends of the side plates 101, 102 extending transversely thereacross, and is secured in place as by screws 116. The plate 115 extends over the block 74 and has a hub 117 on its upper surface.
  • a screw 119 Extending through the hub 117 into a threaded opening 118 in the upper end of block 74 is a screw 119 which has a knob 121 secured to its upper end. The lower end of the knob rests against the top surface of hub 117, and a collar 122 positioned beneath the plate 115 is pinned to said screw.
  • the belt assembly may be raised or lowered as desired.
  • the belt assembly 100 may be adjusted to space the lower end 123 thereof, which defines a gauge, a desired distance from conveyor belt 34 to permit but a single box blank to pass thereunder in the manner hereinafter to be described.
  • pulleys 127 and 128 Positioned between the side plates 101 and 102, as shown in FIG. 10, and rotatably mounted on suitable shafts 125 and 126, are pulleys 127 and 128 which are encompassed by an endless belt 129, desirably having a ridged outer surface.
  • the outer run 131 of the belt rides over the backing plate 106, and the inner run 132 of said belt rides around a pulley 133 rotatably mounted between the side plates, and also around an additional drive pulley 134.
  • the shaft 135 mounting the Pulley 133 has reduced diameter ends which extend through elongated slots 136 in each of the side plates, and is adapted to be moved by means of screws 137 extending through bores 138 in said side plates to adjust the tension on the belt 129.
  • the bushing 141 mounting the pulley 134- has a bore extending therethrough, illustratively hexagonal, adapted to receive a correspondingly conformed shaft 142 to drive said pull
  • a substantially rectangular plate 151 is secured to the standard 69 and extends outwardly therefrom.
  • a drive motor 152 which is connected through a universal joint 153 to said shaft 142. to drive the latter when said motor is energized.
  • the advance of the box blank is controlled by rotation of a cam 156 mounted, for example, on one of the printing roller shafts 157.
  • the guides 53 (FIGS. 6, 7) with the fins 65, are spaced along the support 52 so that the open box blanks may fit between the fins 65 with but little clearance, and the other guide 53, one or more of which may be provided depending upon the length of the open box blank, is spaced between the outer guides 53 and all the set screws 61 are tightened.
  • the belt assemblies 100 are positioned along the bars 66, 67 so that they will be located between the side edges or the box blanks to be fed and are then adjusted by turning knobs 121 so that the lower ends 123 thereof are spaced from the upper run 35 of belt 34 riding around rollers 32, 33 by a distance just slightly greater than the thickness of the box blank to be fed, so that but a single box blank at a time may pass thereunder, the blank immediately therea-bove being restrained by the said ends 123.
  • the hand wheel 48 is rotated to position the support 52 so that when a stack S of box blanks (FIG. 4) is positioned on the inlet end of conveyor belt 34, between the outer guides 53, the trailing edges 64 of the blanks will rest on the rollers '63 of the guides 53 and the leading edges 64' of the blanks will rest against the inclined outer run 131 of belt 132 and the inclined surface 163' of block 163 therebelow.
  • the gauge and stop assemblies 71 As the Spacing between the back stops 53 and. the gauge and stop assemblies 71 has desirably been adjusted to be less than the width of the blanks S, it is apparent that when the leading edges 64 of the blanks are abutting againstthe inclined portion of belt 12? the trailing edges 64 of the blanks will be supported by the back stop. As a result, the weight of the entire stack of blanks will not be supported by the conveyor belt, so that the pressure on the lowermost blank S will not be so great as to prevent ready movement thereof by the conveyor belt 34.
  • the actuator 93 will then be de-energized and, due to the force exerted by coil spring 83, the lever 85 will be pivoted in a clockwise direction. However, as the blank S is directly beneath the lip 86, the latter will abut against the top of the blank, and the movement of the latter will be unimpeded and it will be advanced by the suction belt 34 between the pull rollers 154.
  • the second blank S When the trailing edge 54 of the blank S has been moved past the lower ends 123, the second blank S will then be the lowermost blank, and its leading edge 64 will be forced downwardly beneath said lower ends 123 by the force exerted by the leading edge 64 of blank S immediately thereabove, which will be deflected downwardly by the outer run 131 of belts 129 which are moving in a downward direction reacting against the leading edges as of the blanks in the stack S.
  • the actuator 93 controlling the pivoted lever 85 may be remotely controlled by a micro-switch controlled by a cam rotating in timed rotation with the printing rollers.
  • FIG. 11 is provided, which is substantially identical to the embodiment of FIGS. 1 to 10, and corresponding elements have the same reference numerals primed.
  • each lever 85 is connected to one end of a link 161, the other end of which is pivotally connected as at 162 to one end of a lever 163 which extends through an opening 164 in plate 81 and is pivotally mounted midway between its ends to a boss 165 rigid with said plate 81.
  • the free end of lever 163 mounts a cam follower or roller 166, which coacts with a cam 167 mounted on a cam shaft 168 extending over the conveyor belt transversely thereof.
  • the feeding mechanism to feed a predetermined number of box blanks, and this may be accomplished by retaining the lever 85 in its uppermost position, with the lip 86 spaced from conveyor belt 84 until a predetermined number of blanks has passed thereunder.
  • the control for the actuator 93 in such case could be a counter C (FIG. 1) of any conventional type that counts the box blanks as they are advanced.
  • gauge means has an inclined surface against which the leading edges of the blanks in such stack are adapted to abut, at least a portion of said inclined surface comprising a belt adapted to move downwardly to deflect such leading edges downwardly.
  • said stop means comprises a lever pivotally mounted on an axis extending at right angles to the path of movement of said conveyor belt, and resilient means reacting against said lever normally to pivot the latter in direction to urge one end thereof into the path of movement of such blank to define a stop.
