Abstract
The invention provides a weighing device for a production machine or installation and a method for weighing piece goods from a production machine or installation, which can be implemented in a space-saving manner and/or permit processing of piece goods within a large belt width in the format of the piece goods. According to the invention, this is achieved in that the weight of two or more piece goods (7′, 7″) and the weight which is varied by subsequent feeding or discharge of an individual piece good (7″) or a number of piece goods to be jointly weighed are detected from which the weight of an individual piece good (7″) or a number of piece goods to be jointly weighed is determined from the difference between the weights.
Claims29
A weighing device for a production machine or installation for determining the weight of individual piece goods or individual groups of piece goods within a production line with scales which have a weighing receptacle for two or more piece goods comprising a conveying unit for jointly feeding two or more piece goods to the weighing receptacle and for jointly weighing the two or more piece goods and means for successively discharging individual piece goods to be weighed or groups of piece goods to be weighed with subsequent weighing of the weight remaining on the weighing receptacle and an evaluation unit for determining the weight of a piece good or the group weight of a group of piece goods from a difference between two weight values.
A weighing device for a production machine or installation for determining the weight of individual piece goods or individual groups of piece goods within a production line with scales having a weighing receptacle for two or more piece goods comprising a conveying unit for the piece goods with means for successively feeding the two or more piece goods to the weighing receptacle with successive weighing of the weight which is located on the weighing receptacle and means for subsequently discharging jointly the two or more piece goods which are located on the weighing receptacle and an evaluation unit for determining the weight of an individual piece good or the group weight of a group of piece goods from the difference between two weight values.
A method for weighing piece goods which are provided by a production machine or installation, comprising the step of feeding jointly two or more piece goods to a weighing and conveying receptacle and jointly weighing the goods on the weighing and conveying receptacle, and then successively removing individual piece goods to be weighed or groups of piece goods to be weighed from the weighing and conveying receptacle and then weighing a weight remaining on the conveying and weighing receptacle and employing an evaluation unit to determine the difference between two weight values to obtain the weight of one piece good or the group weight of a group of piece goods.
A method for weighing piece goods which are provided by a production machine or installation, comprising the steps of successively feeding the two or more piece goods to a weighing receptacle of a weighing device and successively weighing the weight which is located on the weighing receptacle and jointly discharging the two or more piece goods which are located on the weighing receptacle with a conveying unit of the weighing device with the weight of an individual piece good or a group weight of a group of piece goods being determined from the difference between two weight values by means of an evaluation unit.
A weighing device for determining the weight of individual piece goods or a group of piece goods in a production line comprising:
- (a) a combination weighing and conveying device for receiving two or more piece goods and then jointly weighing and then successively discharging individual or said two or more piece goods that have been jointly weighed to provide a first weight data to an evaluation unit;
- (b) subsequently weighing a number of piece goods remaining on said combination weighing and conveying device after successively discharging individual or said two or more piece goods that have been jointly weighed to provide a second weight data to said evaluation unit;
- and
- (c) an evaluation unit for determining the weight of an individual piece good or the group weight of a group of piece goods from the difference from said first weight data from said second weight data.
