Problems solved by technology

However, when the weight of the powder and pellets in each weighing hopper is concentrated around the average value of 23g, then under the condition that it is not allowed to be lower than the specified weight, the weight closest to the target is 23g multiplied by 5=115g, and a 15g accident occurs. error

Embodiment Construction

[0023] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Fig. 1a and Fig. 1b are side views of a powder-granule combination weigher according to an embodiment of the present invention. Figure 2a and Figure 2b It is a plan view of a volumetric feeding device for a powder-grain combination weigher installed on the powder-grain combination weigher shown in Figs. 1a and 1b. In FIGS. 1a and 1b, only one unit scale 10 constituting the combination weigher is shown, but in fact, the combination weigher is composed of a plurality of unit weighers. This, in Figure 3a The same applies to the following embodiments.

[0024] The powder-granular material combination weigher of this embodiment has a reciprocating structure in which a plurality of unit weighers 10 are arranged in series. According to this embodiment, the unit scale 10 has a volumetric feeding device 20, and the volumetric feeding device 20 is such as Figure 2a and Figure 2b A...

Abstract

A volumetric feeder 20 is made of a plurality of independent feeder elements 20a, 20b, etc. Each of the feeder elements 20a, 20b, etc. is provided with a stationary portion 21 and a movable volumetric measure 22 that can move back and forth in the stationary portion 21. Each movable volumetric measure 22 is provided with a measure portion 23 for accommodating a predetermined volume of powdery or granular material. The movable volumetric measures 22 in the feeder elements 20a, 20b, etc. are capable of moving, independently of one another, between a powdery- or granular-material-charging position at which the measure portions 23 coincide with charging apertures 24 of the stationary portion 21, and a powdery- or granular-material-discharging position at which the measure portions 23 coincide with discharging apertures 26 of the stationary portion 21.

Description

Technical field [0001] The present invention relates to a volumetric (capacity) feeding device for powder and granular materials and a combination weigher for powder and granular materials. More specifically, the present invention relates to a volumetric feeding device and device that can be used in a scale for powder and granular materials. A combination weigher for powder and granular materials with the volumetric feeding device. Background technique [0002] Figure 9a and Figure 9b Shows the plan view of the conventional multiple volumetric feeder, Figure 8a and Figure 8b A side view of the hopper 95 installed on the multiple volumetric feeding device is shown. As the previous multi-unit volumetric feeding device, such as Figure 9a , Figure 9b and Figure 8a , Figure 8b Reciprocating feeder and rotary feeder shown. Shown in Figure 8a-Figure 9b The volumetric feeding device of the is equipped with a fixed part 91 and a movable weighing hopper 92 that can reciprocate in...
