DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates generally to a metering apparatus, and more particularly, to a metering system adapted for a combination metering machine used to discharge an object of metering (work), such as foodstuff, to the outside every time a predetermined quantity is measured.
BACKGROUND ART
Conventionally known is a combination metering machine, such as the one shown the cutaway side view of FIG. 30, as an apparatus in which an object of metering, such as foodstuff, is distributed to a plurality of hoppers and weighed in individual batches, a combination of the batches is selected so that the sum total of individual measured weight values is approximate to a target value, and the selected batches of the object of metering are discharged and joined, thereby obtaining a variable resembling the target value.
This apparatus comprises a circular feeder 21 provided in the central portion of the apparatus, a plurality of straight-advance feeders 22 arranged extending radially from the central portion, intermediate hoppers 23 and metering hoppers 24 arranged individually under the straight-advance feeders 22, open-close mechanisms 25 for the hoppers 23 and 24, a discharge chute 28, a collecting chute 26, and a collecting hopper 27.
When the object of metering is transported to the circular feeder 21 by means of a conveyor or the like, in this apparatus, the object of metering is radially distributed and introduced into the individual intermediate hoppers 23 by means of the straight-advance feeders 22. The respective discharge gates of the intermediate hoppers 23 open as the open-close mechanisms 25 are driven, whereby the contained object of metering is discharged to the corresponding metering hoppers 24. The metering hoppers 24 receive and weigh the object of metering discharged from the intermediate hoppers 23. The open-close mechanisms 25 are operated to open the respective discharge gates of the metering hoppers 24, thereby allowing the object of metering to be discharged through the gates, so that the quantity of the object of metering can be approximated to the target value by combining the batches of the object of metering contained in the individual metering hoppers 24. The batches of the object of metering from the metering hoppers 24 are collected in the collecting chute 26 by means of the discharge chute 28, discharged through the collecting hopper 27 to be, for example, bagged, and transported to the next stage.
The above-described combination metering machine can be used for metering a bulk material. If it is used to meter a sticky material, however, it is subject to various drawbacks such that the sticky material adheres to and remains on the inner surface of each hopper, thereby lowering the metering accuracy and processing speed, and its maintenance takes time.
To avoid this, a net is provided on the inner surface of each hopper so that the contact surface between the hopper and the object of metering is reduced to prevent the object of metering from remaining on the inner surface. In this case, however, arranging the net takes time, and the net makes it more difficult to clean the inner surface of each hopper. Therefore, the previously handled object of metering is left even after the cleaning, thus entailing insanitary conditions, and the metering accuracy is lowered.
Moreover, the net is liable to be damaged during the cleaning operation, and resulting metal pieces may possibly be entrapped.
Conventionally, furthermore, the individual hoppers are arranged circumferentially along the side face of the metering machine, a cleaner must make a round of the side portion of the metering machine as he or she cleans all the hoppers. In the conventional combination metering machine, moreover, the hoppers cannot be easily removed.
FIG. 31 is a front view showing a conventional combination metering machine in which a plurality of batches of an object of metering (work) are combined to a predetermined weight as the object is discharged.
This combination metering machine, which compr
