Problems solved by technology

[0007] However, in this continuous quantitative discharge device, two material storage containers are required, and a metering unit needs to be provided in each of these two material storage containers, so there is a problem of increasing the size due to the complicated structure.
[0008] In addition, since the continuous quantitative discharge device is a structure in which the two material storage containers are synchronized with the quantitative discharge device, there is a problem that, when a large amount of material is continuously discharged, etc., the material storage container will not Waiting until the material can be discharged quantitatively, or in order to discharge the material quantitatively in any material storage container, it is necessary to perform adjustments such as reducing the discharge amount or reducing the discharge speed, and the material cannot be discharged smoothly and continuously
[0009] Furthermore, since each load cell for measuring the two material storage containers is a structure that supports the outside away from the center of gravity of the material storage container, errors are likely to occur when measuring the mass in the material storage container, and it is impossible to accurately The problem of measuring the quality of the material being stored
[0010] In addition, even in a compounding device in which a plurality of continuous quantitative discharge devices are installed continuously, there is a problem of further complexity and size.
[0011] In addition, since the above-mentioned blending device has fixed discharge ports from each of the continuous quantitative discharge devices, the materials tend to vary depending on the discharge amount or the type of discharge materials, etc., so that there is a problem that the mixing ratio of the materials to be mixed is not uniform.

Abstract

To provide a continuous fixed quantity discharging device and a material blending system using the device reduced in overall size and capable of accurately, smoothly, and continuously discharging a fixed quantity of material and mixing the discharged material at a uniform mixing ratio. This continuous fixed quantity discharging device comprises a material reserving tank (1) for reserving the material (Z) continuously fed by a supply means (10), a material storage tank (2) having a material inlet (21) separated from the material reserving tank (1) formed at the upper part, storing the material (Z) fallen from the material reserving tank (1), and having a discharge device (22) capable of continuously discharging the fixed quantity of the reserved material (Z) formed at the lower part, a load cell type mass weighing part (3) formed by installing a carrying arm (31) connected to only the material storage tank (2) in the material storage tank (2) and supporting the carrying arm (31) by a load cell (33) installed on a support frame (32) separated from the material storage tank (2) in a non-contact state, and a control part (4) monitoring the values weighed by the load cell (33) and controlling the discharge of the material by the discharge device (22) and / or the supply of the material into the storage tank (2) by the discharge device.

Description

technical field [0001] The present invention relates to a continuous quantitative discharge device of a weight loss compensation method and a material blending system using the same. The above-mentioned stored material is discharged, and the material whose mass has decreased is regarded as the discharged material, and a certain amount of material can be continuously discharged. Background technique [0002] As a means of continuously discharging a certain amount of material, a weight loss compensation method is known. [0003] As a conventional continuous quantitative discharge device based on this weight loss compensation method, it is composed of a metering device, a supply device, and a control device. The material storage container, and the metering part composed of a quantitative discharge device arranged at the lower part of the material storage container; the supply device can supply to both of the above-mentioned metering parts arranged in parallel; the control devi...
