Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a bulk flow system for collecting a flow of material, for example a cavernous material, and for performing summative measurements of continuously discharged portions of that material. Regarding formal scales.

Problem to be Solved by the Invention The object of the invention is to provide a device which is of simple design and is capable of operating with high precision.

Means for Solving the Problems According to the present invention, a batch weighing device as specified in claim 1 is obtained. Because the tiltable weighing container is a simple and effective container design to operate, and because only the added weight is measured for each weighing, the coupled motor arrangement can be used to prevent, for example, slow dissipating oil. Therefore, it will be understood that even if their weights are changed, they will not cause any errors in scale.

A very important aspect of the invention is to enable the components of the continuously supplied material to be received from the goods container in a mixed manner if the bottom of the container has a rounded shape. The device has been found to be further useful for dispensing. This means that, for example, feed mixtures can be obtained on the basis of precise measurements of single components, but they may be affected by the tilting of the container causing the bottom layer to slide on the bottom or "transfer" and thus the flow of material leaving the container. will generally contain materials from both or all layers and will therefore have been mixed by the time they reach the appropriate container as these materials flow down from the mouth of the container, so that subsequent mixers - It means that it is allowed to cool without using a unit by continuous feeding into a capacity container and then deposited therein in layers.

Examples and effects The invention will now be explained in more detail with reference to the drawings.

FIG. 1 shows a bulk weighing device comprising an outer housing 2 with an open bottom and an upper inlet opening 4 for receiving particulate matter to be aspirated before discharging through the open bottom. . - By way of example, the substance is fed via a tube 6 from a conveyor 1 quarm 8 driven by a motor 10. An inspection opening covered by a lid 12 leaks into the upper part of the housing 2 .

Inside the housing 2, there are shaft bins 1 facing each other in the direction of the ends.
A rotatable, normally upwardly opening container 1 having 6
4 are arranged, and the containers are suspended via axle bins through their respective capacity compartments 20 to brackets 18 suspended from the ceiling of the housing. At one end (front end) of the container 14, the bracket 18 has a gear box 22 and an associated motor 24 operable to rotate the container between the illustrated position and an inverted empty position via the gear box 22. will be provided.

The housing 2 includes an electronic control device externally coupled to the drive motor 10 of the worm 8 and/or any other device thereof for effectively stopping and resuming the flow of material to the container 14. Registration unit 2
6 is attached.

A conveyor device, not shown, is arranged below the housing 2 for conveying the material from the cow station to a suitable point of use or places of use, for example a series of feedlots. Also good.

The control unit 26 operates the device as follows:
Please refer to FIGS. 1 and 2.

The motor 10 is operative to discharge material into the container 14 via the inlet 4. The weight of the container is measured by the cross section 20 coupled to generate a control signal responsive to the weight of the container reaching a predetermined value corresponding to the desired weight of the material portion within the container. This control signal causes the motor 10 to stop or the container 1
4, and this control signal is used to correspondingly activate a mechanism that shuts off the flow of material to pipe 6, and this control signal is used when the container 14 is ready to be weighed with sufficient accuracy, i.e. from pipe 6. A delay unit or "pause detector" is also provided which is adapted to activate the weighing device while the material is still flowing down.

The weighing results are displayed on the unit 26 and a signal is then generated to start the motor 24, which rotates the container to its inverted empty position and then back again.

A control signal is then sent back from the control unit to said idle indicator, which in turn sends a new signal indicating the weight of the empty container to the registration unit 26, which unit then registers full and empty respectively. A subtraction is performed between the container weights. The result of this subtraction, which indicates the exact weight of the material portion to be processed, is transferred to the summation register and a new operating cycle can be started by restarting the flow of feed material.

The latter register therefore always indicates the full weight of material dispensed by the Hiyodai device since the last reset of the Korean device.

In order to obtain a dispensed material portion with a weight close to the preset weight, the difference between these two weights is determined for each weighing amount and the "preset weight" for the next cycle is adjusted accordingly. The unit 26 may be designed accordingly.

As mentioned above, an important aspect is the ability to simultaneously dispense two or more successively nearly parallel layers of material, so that when the materials reach the container they are mixed. Located in the Hiyo 9 container. The tube 6 can be connected to a feed worm 28 with an IJ port, which can be driven by a motor 10, and during operation the volume container is filled with material from the first worm and then from the other worm in the disclosed manner. The components of the first worm and then the other can be accurately weighed. Needless to say, each preset 1 should correspond to the desired ratio between the open components and, as already mentioned, an automatic adjustment of the presets ff1fflJ may occur for both components respectively. .

Thus, as shown in FIGS. 2 and 3, the first component (A) is deposited on the bottom of the container 14, and then the layer (A) is deposited on the bottom of the container 14.
Component CB) is deposited neatly on the top of ). The container is then tilted as shown by the arrow, and the two layers move relative together along the curved bottom of the container until the lower edge of the mouth of the container reaches substances (A) and (B). When turned sufficiently and then further downwardly, the container dispenses a total amount of material from both layers (A) and (B) simultaneously;
In this way both components are gradually emptied.

These are mixed continuously as they flow down into some container.

In FIGS. 1 and 2, the container 14 has a straight earthen wall, but in FIG. I am doing it.
