Title: Improvements in or relating to bag packer weighing assembly
IPC: F16C32/02
Filed: 1961-03-29
Abstract: 928,988. Weighing-apparatus. H. L. STOKER CO. March 29, 1961 [March 30, 1960], No. 11471/61. Class 143. Apparatus for packing bags with a preselected weight of material comprises a scale beam 40 fulcrumed at 63, a weighing platform 30 connected, through a pivot 65 and member 50, with a pivot 64 on the scale beam adjacent the fulcrum 63, and a counterbalancing weight beam 43 connected through a member 42 to the opposite end of the scale beam 40, so that the scale beam acts as a lever of the second order. The fulcrum 63 comprises a 60 degree knifeedge in a 120 degree slot, the latter having tungsten carbide inserts. A counterpoise weight 51 on the weigh beam 43 and a counterpoise weight 52 on the scale beam 40 provide zero adjusting means. The weighing platform 30 includes a bag support 60 and bag-filling spout 34, these two being counnected by a channel member 61. The weighing platform 30 is connected to the frame by straps 32 of clock spring steel. Material from a hopper 36 is fed to the spout 34 by a screw conveyer (not shown) which operates in a U-trough 35 and is driven by a motor 37. The counterbalance is set to a preselected weight by a hanger weight 45 suspended from the weight beam and by adjusting the position of a poise weight 44 along the weight beam. The arrangement of the scale beam as a lever of the second order and the weight beam as a lever of the first order results in a high amplification of movement and the movement of the end of the weight beam is used to vary the distance between two capacitor plates 47, 48. The variation in capacity is used to control the operation of the screw conveyer drive. At a predetermined capacity, corresponding to the preselected weight of material to be packed, an electrical circuit through a forward drive relay for the screw conveyer motor is broken and a reverse drive timer is actuated. This completes a circuit through a reverse drive relay for a predetermined duration, thereby causing the screw conveyer to be driven in the reverse direction to provide a sharp cut-off in filling. An " over/under " indicator 53 is attached to the end of the weight beam to give a visual indication of weight.
