Abstract: 613,150. Endless-belt conveyers. MONACO, G. C. April 15, 1946, No. 11536. [Class 78 (i)] In apparatus for transferring articles, particularly baked objects such as crackers, biscuits and fig bars, from a flat position on a cooling conveyer to stacked upright position on a packing conveyer by means of a belt conveyer, jamming of the articles at the point of delivery to the belt is prevented by mechanism, such as a wire brush, an endless belt or a wire drum, the moving surface of which frictionally engages the upper surface of each article. The articles are transferred from the conveyer belt 132 of a cooling conveyer system 20 to a belt 24 of a receiving table 12 by passing under and in contact with a soft rubber drum rotating at a greater speed than either of the belts. The drum comprises a hollow cylindrical roll 144, covered with soft, resilient rubber, on a shaft 152 situated between and above the conveyer belts 132 and 24 and in contact with the articles. At the ends of the shaft 152 are bearings 156 formed on the ends of links 158 which are pivotally mounted on side pieces 40. Means to adjust the horizontal position of the roller comprises bearing blocks 160 pivotally connected to the links 158 and engaging a vertical screw shaft 162 mounted in bearings 164 on the side member and turned by a handle 166. Means to rotate the shaft of the roller 152 comprises a sheave 168 driven by a shaft 170 from a sheave 172 rotatably journalled in the side member 40 and actuated by a common source of power, the speed of rotation being slightly greater than that of the belt 24. The stacking machine 10 comprises a receiving table 12 with feeding troughs 14 and means 16 for stacking articles all supported on a frame 18. The receiving table 12 comprises an inclined endless conveyer belt 24 supported by an inclined plate 44 passing over rollers journalled in the side pieces and having feeding troughs 14 formed by strips 46 and comprising an inclined part 48, and part 50, part of the stacking cam feeding chute and a horizontal part 52 on a packing conveyer belt 54 supported on a plate 66. The steep part 50 is supported on a slide 68 and has parallel slots in which strips are received and a projecting part of a strip is securely held in a hole in the slide. The inclined part is enclosed by a topping strip 74 with an auxiliary end plate 76 to adjust the position of discharge. The topping strips are supported by a rod 78 and are adjustable. The connection between the strips 50 and 52 is such as to enable a roller 64 of the belt 54 to be placed directly under the discharge point of the articles. At the receiving end, separator strips for the troughs 14 containing the articles are pivotally attached by pins 116 to a shake bar 118 to direct the transfer of articles into the troughs of the belt 24 from the system 20. The shake bar 118 has rollers 120 positioned in horizontal slides in guide blocks 122, and roller 124 fixed to the bar rides on a cam 126 rotating with a pulley 28. The roller 124 is held in contact with the cam 126 by a spring 130. Means 16 for vertically stacking articles comprises a shaft 102, rotatably journalled in the side members and having a number of stacking plate cams 104 maintained in position by collars. The lower half of the cams are in a grating 110 which comprises short, parallel bars 112 supported on a cross-rod. The bars stop the descent of the article when it reaches the level of the packing conveyer belt 54. U.S.A. Specification 2,358,413 is referred to.
