12 Claims.

the delivery belt at its forward end only, and to obtain and maintaina pulling action on the upper stretch to keep the stretch taut at all times, and to urge it against the overlying pressure unit, or interposed articles, thus automatically adjusting the space between the belt and the pressure unit conformably to the varying thicknesses of the lapped or stacked articles; particularly. where feeding is irregular, and where, but for this invention, the stack wouldbe irregular. This device insures continuous feeding in the direction of belt travel.

A further object is to provide an improved pressure unit, consisting of means, in this instance linked roller sections, adapted for what may be termed caterpillar action, to automatically compensate for varying thicknesses of lapped articles, due to uneven feeding, and acting to main-- tain uniform pressure on the glue seam of a foldedcarton or box blank, to insure firm adhesive seal ing and prevent opening of the blank while it is under the pressure unit.

Other objects of my invention will appear from the following detailed description of the drawings, and in said drawings Figure 1 is a longitudinal sectional elevation of my delivery mechanism, as before delivery of blanks thereto, illustrating the manner in which the pull on the upper stretch causes the stretch to bear against the drive pulley pressure section, thus delivering the slack into the lower stretch of the belt;

Figure 2 is a view similar to Figure 1, showing the cartons or box blanks irregularly fed into the delivery, and illustrating the manner in which the conveyor belt is permitted to sag below the drive of the pressure unit to make room for the folded cartons or blanks, taking the surplus length of belt. from the slack in the lower stretch. This figure also shows the manner in which the hinged roller trucks of the pressure unit adapt themselves to the uneven surface of the upper sides of the unevenly fed cartons or box blanks;

Figure 3 is a side elevation, with the machine shortened by breaking away the middle of the apparatus;

Figure 4 is a detail longitudinal section showing the delivery mechanism set up for overhead stacking;

Figure 5 is a view similar to Figure 4, with the mechanism adjusted for underneath stacking;

Figure 6 is a plan view of my invention with a portion of the center broken away as in Figure 3;

Figure 7 is a section on line 'l-l of Figure 3,

' looking in the direction of the arrow;

Figure 8 is a top view of the linked roller sections of the upper pressure unit, and some of the associated parts;

Figure 9 is a plan section showing the manner of linking the roller sections;

Figure 10 is a section on line Ill-l0 of Figure 7; and

Figure 11 ley of the pressure device, illustrating the manner of adjustably mounting same on the drive shaft.

Referring to the drawings, 2 generally indicates a paper box machine, including feeding delivery belts 3 and 4 which are adjustable to deliver the folded carton, box or blank to a slower moving conveyor belt 5.

The conveyor belt 5 is driven by a drum 6 mounted on a shaft 1, to which shaft is keyed a worm wheel 8, see Figures 3 and 6, meshing with a worm 9 that in turn is keyed to a shaft Ill. The shaft I0 is driven from the box machine at different speeds through a selective chain mechanism II. The particular speed is selected by the operator and depends upon the length and thickness of the article which is to be handled. Mounted on the shaft ill is a'worm l2 meshing with a worm wheel l3, mounted on a stud l4.

To the worm wheel I3 is secured a sprocket l5 having chain I6, see Figure 7, operating sprocket H which is keyed to a stub shaft i8 having spur gear IS. The stub shaft l8 operates in a bearing 20. The gear IS in turn meshes into a spur gear 2| which is secured to a shaft 22, in turn driving a pulley 23, see Figure 11, splined to the shaft 22 as at 24. The pulley 23 is kept in position by a forked member 25, see Figures 8 and 4, which is secured to a tube 26 having a curved member 21 and a pivot at 28 in the foremost hinged truck section 29. This truck carries a pulley 30 over which passes a belt 3| which also passes over pulley 23.

Attached to the inner end of truck section 29 is a second truck 32. This is a hinged attachment concentric with a roller 33 of truck 39 (see Figure 9). The hinging is accomplished by a stud 32' passing through openings 33' in the ends of the sides of the truck members 29 and 32. The ends of the side members of truck 29 and the corresponding ends of the side members of is a sectional detail of the drive pulthe truck 82 are halved together to present an even or flush surface on the outside. In this em bodiment, four roller trucks are employed to obtain a kind of caterpillar structure and action,

that is a flexible action. The ends of the sides of the trucks I2 and 34 are connected in the same manner as the ends of the sides of trucks 2. and 82. Each hinge roller 32, i5 and 81 is provided with a sleeve 35', which passes through the offset ends of the truck sides and serves as a spacer to keep the straight ends of theside members of truck 32 apart, and with said ends pivoting on the ends of the sleeve 35'. This permits tightening of the stud 32' without binding on the pulleys 33, 35 and 31.

Mounted on the roller truck ,3 is a U-shaped casting 35 which straddles the tube 25 and serves as a rear guide for the linked connecting trucks to allow vertical but prevent lateral motion. Mounted at the top of the member 38 is an arm 29 which is provided with an idler pulley 40 to take up the slack in the belt 3|, when the trucks raise due to variation in thickness of the stack of lapped cartons, boxes or blanks.

To adjust the shaft 22 (which carries pulley 23) for diflerent heights, see Figures 6 and 7, it is provided at opposite ends with levers 4| each having a rack 42 on its upper arm meshing with a pinion 43 of shaft 44. A hand wheel 45 is provided on the shaft 44 for adjusting the shaft, and a' clamp screw 46 holds the shaft 44 in rigid adjusted position.

The upper stretch of the belt 5 is supported by a roll 41 at the forwardmost position and a roll 48, and is also supported by a flat board 49 and by a flat board 50. The board 50 serves'to hold the belt 5 in flat condition in the region of the upper pressure device to prevent weaving at this point and to insure accurate drying of the glue seam without slipping the seam during the drying process. A pulley 5| supports the belt when the conveyor is filled with blanks, as shown in Figures 2, 4 and 5. Another pulley 52 supports the belt at the feeding end of the box machine or receiving end of the delivery mechanism. This pulley 52 is adjustable in a slot 53 of arms 54 secured to a shaft 55 which in turn is mounted on a bracket 55 secured to a frame member 51. Arms 54 are adjustable in a vertical plane.

The pressure section, including the pulley 23 and the rollers 48 and 5|, is mounted on a carriage which consists of a bracket 58 and 59 having rollers 50 to bear on the upper surface of the frame 51. A pair of longitudinally extending tie rods 6| connect the brackets 58 and 59 and provide an adjustable support 62 for the roller 5|. The adjustable support for the roller 5| consists of a threaded shaft 63 adjustable in the vertical direction and held in adjusted position by spanner wrench nuts 64 and 55. .The board 50 is hinged at the forward end about the shaft which supports roller 48 and its degree of inclination can be varied also by means of the shaft 68. In this case, the roll 5| is mounted on the board and both roll and board are adjusted together.

A pair of brackets 55 (see Figures 7 and 10) mounted on the bracket 58, support the upper pressure section through a pin 6'! and a sleeve 68 that furnish a pivot for the sector member 42.

A suitable belt tightener, see Figure 3, includes tightener roll 59, controlled by the tightener lever 10, having ratchet teeth II and a pawl 12. The purpose of this tightener is to control excessive slack in the belt 5 due to possible stretch inuseandalsotoguidethebeltunderthecross shaft It on the movable carriage which supports the bracket 58. v
