Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for automatically supplying raw cotton to a mixed batting machine.

Conventionally, as a means of supplying raw cotton to a cotton mixing machine in a spinning factory, various raw cotton packages are unpacked in advance and each raw cotton (hereinafter referred to as open bale raw cotton) is
are arranged on the floor near the cotton mixing machine, and workers manually strip small chunks of raw cotton from these open bales of raw cotton.
A method is adopted in which various kinds of raw cotton are piled up at a predetermined ratio on a crisscross that is moving at a low speed and then fed to a hopper bale breaker of a cotton mixing machine.

However, this method relies on the experience and intuition of workers, and the amount of raw cotton to be stripped varies widely, the mixing ratio is uneven, it requires a large number of workers, and it also causes fluff and cotton dust. This is unfavorable from an occupational health standpoint as there is a lot of scattering and the work is in a bad working environment.

Moreover, spinning mills tend to change count frequently these days, and it is necessary to change the blending ratio of various raw cottons, but this is complicated and difficult to achieve an accurate blending ratio. be.

The present invention has been made in view of the above, and involves scraping a plurality of open bales of raw cotton for each type, and automatically feeding the raw cotton to a mixing and batting machine at a raw cotton supply ratio predetermined in a cotton distribution plan. It is an object of the present invention to provide an automatic method for supplying raw cotton to a cotton mixing machine in which raw cotton is selected, transferred by an air flow, mixed, and then supplied to the cotton mixing machine.

In the illustrated example, each mixing machine M is equipped with a suction fan, and the opened raw cotton is fed by suction airflow to the feeding device B.
The structure shown here is such that each supply device B is provided with an air supply fan, and the raw cotton opened by the spike rollers 15 is sucked, and the raw cotton is transported via the transport duct D. It may also be sent to mixing M.

S indicates a control device, in which the distribution of raw cotton bales is memorized according to the blending plan for each cotton blending machine C based on the spinning count, and based on this, the selection of the required supply device B and valve mechanism V and the predetermined blending are performed. In response to a supply signal from the mixing M of the batting machine C, supply to the mixing M is started, and when the storage amount of the mixing reaches a predetermined value, a supply stop command is issued.

In addition, 45 in the figure is an exhaust duct provided for each mixing M1, M2, . . . .

Next, its effect will be explained.

For example, as shown in FIG.
0'S, 30'S, 20'S, and the blended cotton varieties for each count are as shown in FIG. 5, and these are stored in the control device S in advance. In this state, for example, when supplying raw cotton to the mixed batting machine C1, the valve mechanisms V1 and V2 are released (the mixing M1 is communicated with the main duct 40), and the valve mechanisms V3, V4, V5
is closed (the mixing M2, M3 are shut off from the main duct 40), and the valve mechanism V7 shuts off the branch duct 43 from the main duct 40. These are control device S
This is done by Next, the supply devices B1, B2,
Activate B3 and B4, open bale raw cotton WA,
The WB, WC, and WD are scraped off from the upper surface, and the intake fan of the mixing M1 is operated to supply the scraped raw cotton to the mixing M1. In this case, it is assumed that the amount of raw cotton fed into the mixing M1 is greater than the amount per unit time fed from the mixing M1 to the mixing and batting machine.

When mixing M1 reaches the predetermined storage amount,
The supply is stopped and then mixing M2 is supplied in the same manner.

Similarly, for mixing M3, supply device B
3, B4, B5, and B6, and supply devices B6, B7, and B8 for mixing M4, respectively, and select valve mechanism V to supply each mixing.

Also, each turntable 1 of supply device B
When the upper open bale raw cotton is consumed, for example, a limit switch or the like detects that the lifting frame 16 has descended to a predetermined position, the lifting frame 16 is raised, and a new open bale raw cotton that has been placed in the supply path 46 is placed in advance. replenish. In this case, it is preferable to make the heights of the open bales of raw cotton that are placed in parallel on the rotary table 1 the same, so that the parts that are too high are stripped off, and the stripped raw cotton is stacked with the top surface aligned. Fill between open bales of raw cotton.

In Fig. 5, for example, an example is shown in which open bale raw cotton WA, WB, WC, and WD are supplied in the same amount to the mixed batting machine C1.
The supply ratio can be changed to a predetermined supply ratio by appropriately adjusting the tact amount of 3 and B4, that is, the descending speed of the elevating frame 16.

As described above, according to the present invention, open bales of raw cotton are sequentially scraped by type using separate scraping and feeding devices, and the required types of scraped raw cotton are selected based on a cotton distribution plan corresponding to the spinning count, etc. transported by air flow,
Since the raw cotton is mixed and supplied to the mixing and batting machines, the type of raw cotton to be supplied to each mixing and batting machine can be arbitrarily adjusted, and therefore specifications can be changed very easily. In particular, even when different cotton distribution plans are required for a large number of cotton blending machines, it is possible to supply each raw cotton according to the required supply ratio to each blending machine, which saves labor and improves quality. It has the effects of improving productivity, improving productivity, and cleaning the indoor environment without generating cotton dust.
