Title: Device for packing solid in a fixed quantity
Inventor: TANAKA TATSUO
IPC: B65B39/00
Filed: 1994-05-18
Abstract: PURPOSE:To enable a fixed amount of solid identified to be packed by collecting in a discharge pipe only the solid part of a subject to be packed, and freely varying the amount of discharge of a pump means according to sensor signals. CONSTITUTION:When a measuring piston 1 takes main measurements of product capacity, a pump means 3 feeds a product including a solid, and is stopped when a set value is reached by the measurement of the solid by a discriminating sensor 6. In this case, the piston 1 measures the amount of packing of the product irrespective of whether the means 3 is being operated or stopped, and a switching valve 2 opens in three ways. When the amount by which liquid is fed by the means 3 is smaller than the amount by which the product is packed, the piston 1 sucks the height of liquid corresponding to shortage, from a liquid conduit 9. When the amount by which the liquid is fed is greater than the amount by which the product is packed, the height of the solid in the liquid is held in the collecting part (a) of a discharge pipe 7 by a filter 8, and the conduit 9 is filled with only the liquid portion of the product, and extra liquid is forced to flow back into a storage container 4. The solid thus measured is discharged by the piston 1 and packed, with the conduit 9 closed and an exit valve 11 opened by the switching of the valve 2. The solid is similarly packed also when the amount by which the liquid is fed is equal to the amount by which the product is packed.

The circuit 3 consists of switching FETs T1-T4 and external capacitors C1, C2. For example, when the capacitor C1, C2 of the same capacitance are connected as shown and a cell 10 is connected between VDD, VSS1, a voltage twice as large as the VSS1 at VSS2 is connected between VDD and VSS1 and the cell 10 between VDD and VSS2, a voltage half as much as VSS2 is generated at VSS1. Accordingly, changing-over the external position of the capacitor C2 and the connecting terminal of the cell 10 makes it possible to use the same IC for both, e.g. a silver cell and a lithium cell of different electromotive forces.
