초록 ▼

An apparatus and method for automatically removing dough pieces from overhead dough proffer, weighing the dough pieces and reinserting them back in to the process stream. The weight information is analyzed to determine whether it represents the weight of pieces or the empty scale weight, and may be used to provide a signal proportional to the weight of a dough portion, or group of dough potions in order to automatically adjust the rate at which dough is fed to the dividing mechanism, thereby increasing or decreasing the dough piece weights to maintain the desired amount of dough per piece.

대표청구항 ▼

1. An apparatus for dividing a continuous flow of dough into a plurality of portions, each portion having a substantially uniform preselected target weight, comprising: a dough divider configured to receive the continuous flow of dough and to divide the dough into portions sized in proportion to an operating rate that is controlled by an operating rate control signal;a proofer downstream from said dough divider configured to receive and transport the individual dough pieces as they are released from the dough divider;a weighing conveyor downstream from said proofer configured to receive and transport said portions at an average speed equal to the speed of the proofer, the weighing conveyor having a load cell configured for producing indications representative of the weights of a portion resting for an interval in a resting position on a segment of the conveyor positioned over the load cell, the weighing conveyor having a servo motor which is programmed to drive the conveyor and to stop the conveyor for the interval in the resting position so that each successive dough piece is positioned to rest on the segment of the conveyor positioned over the load cell; and,a processor in electrical communication with the dough divider and the load cell, the processor programmed to: send the operating rate control signal to the dough divider,receive a group of a predetermined number of successive weight indications from the load cell,calculate the average weight indication of the group,determine whether all of the weight indications in the group fall within a predetermined standard deviation of the average weight indication of the group, and if so,calculate the difference between the average weight and the sum of the target weight and the tare weight of the segment of the conveyor;and if the difference is less than a predetermined tare setpoint, to use the average weight as the tare weight for subsequent weight indications;and if the difference is greater than the predetermined tare setpoint, to include the average weight indication of the group in an array of a predetermined number of weight samples, calculate the average of the weight samples in the array, and adjust the operating rate control signal according to the difference between the average sample weight and the sum of the preselected target weight and the tare weight. 2. The apparatus of claim 1 wherein the segment of the conveyor positioned over the load cell is configured to accommodate a single portion, and the predetermined number of successive weight indications received from the load cell is selected to encompass a time period less than the interval between loading the positioning of successive portions in the resting position on the segment of the conveyor positioned over the load cell. 3. The apparatus of claim 2 wherein the predetermined number of successive weight indications received from the load cell is selected to encompass a time period less than the interval during which a single portion rests on the segment of the conveyor positioned over the load cell. 4. The apparatus of claim 2 wherein the predetermined number of successive weight indications received from the load cell is selected to encompass a time period less than the interval between the movement of a single portion away from en the conveyor segment and the positioning of the next successive portion on the segment of the conveyor positioned over the load cell. 5. The apparatus of claim 1 wherein the load cell comprises a high precision electromagnetic force coil weigh cell. 6. The apparatus of claim 1 further comprising a tipper downstream from said proofer and wherein the proofer comprises trays which are tipped by the tipper to allow the portion to fall to the weighing conveyor.
