Technical Field

The invention relates to a method and a system for producing a mixture of artificial fibre components.

Background

Since the 50 s of the 20 th century, bag breakers with scales have been used for the production of continuous mixes (mix) which were discarded onto ordinary conveyors. The bale breaker is placed with its axes aligned in a straight line and the scales deposit their weights on top of each other. This is also maintained when the scale is later loaded by a tower (tower). The conveyor belt is timed in such a way that: the disposal of the scales ends with each other. Since the number of reject items is difficult to increase to more than 4 items per minute, the weighing container must be designed higher in order to achieve high performance. This results in a higher quality of fibre being accumulated and makes it necessary to design the bale breaker higher. Milling (milling) these fiber piles is particularly difficult. Feeding the fibre stack to the opening roller and compressing it so that the fibres can be opened is problematic. The layers are typically displaced so that the mix separates. Since at least three rejects of the currently required mixing ratio (if three components are present) have to be predetermined, it is completely impossible to operate two or three production lines with different mixing ratios simultaneously.

Disclosure of Invention

These disadvantages can be solved in a simple manner by the invention.

According to the invention, the scales are not placed in line with the longitudinal axes of the rollers aligned next to each other, but rather are placed axially parallel with the longitudinal axes of the rollers not aligned next to each other.

On the conveyor belt, the rejects for the mix are not made one after the other, but are made simultaneously parallel next to one another. The reject that has been made simultaneously is processed simultaneously at a common opening roll.

Drawings

Figure 2 shows a system for producing a mix of artificial fibre components according to the invention.

Detailed Description

Figure 1 shows an old system. On a long, narrow conveyor belt 1, the reject of scales W1, W2, W3 is sent to an opening system 2. For example, the broken-up debris is sucked out by a fan. After each discard, the first scale discard is further transported a predetermined length such that the second and third scale discards accurately drop onto the previous discard. By means of the opening system consisting of the feed element and the opening roller, the accumulated fibre mass is broken up into pieces and mixed.

The new structure in fig. 2 is completely different.

The conveyor belts 1 are short and wide and the waste are positioned adjacent to each other when viewed along their longitudinal axis. The dispositions W1, W2, W3 occur substantially simultaneously such that they lay adjacent to each other on the conveyor belt rather than on top of each other. The less tall opening system is wide enough but not complex and after opening, the fibre reject is sucked out simultaneously together, for example by a fan. Mixing occurs in a conventional suction system 2 through a line in which the fibers are typically rotated. Thus, after each disposal, different mix ratios can be generated by the control computer and different mixes can be provided for two or three consumers.

For example-the following dispositions:

1)40:30:30 to machine A

2)10:40:50 to machine B

3)40:30:30 to machine A

4)40:30:30 to machine A

5)70:20:10 to machine C

6)10:40:50 to machine B

Thus, a scale system with a large weighing platter may replace three weighing lines.

Since the disposal is usually done with a pneumatic cylinder and the disposals are not precisely located, a tolerance of up to 20 seconds will have to be assumed for simultaneous disposal and simultaneous treatment.
