Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for collecting and measuring falling cotton in a collecting apparatus for collecting cotton which collects and compresses cotton generated in a spinning machine such as a comber.

[0002]

2. Description of the Related Art In a spinning factory, different types of cotton drop are generated from each spinning machine, and as a treatment for this, generally, they are manually selected, transported, weighed, and put into a manual compression packing machine. A means for compressing and banding is adopted. However, this packing work is labor-intensive, a large amount of dust is generated, the working environment is bad, and the work is most disliked by the worker.

Therefore, the inventor of the present invention has previously provided an apparatus for effectively collecting, compressing and packing cotton litter (Japanese Patent Application No. 2-41).
2470). In this device, cotton wool is loaded in a predetermined weight on a carrier, which is temporarily accumulated in a stockyard, and then the carrier is transferred to a compression packing device to compress and pack the cotton wool.

[0004]

In this case, it is necessary to keep the packed weight of the cotton wool constant in terms of trade, and therefore, it is necessary to measure the weight of the cotton wool to be supplied to the transport vehicle in advance. However, the specific gravity of dropped cotton is extremely small, and it is difficult for a conventional measuring instrument to be bulky, and cotton dust is scattered, making it difficult.

The present invention focuses on the fact that the amount of cotton drop is almost constant, even though the amount of cotton drop, such as comb, is intermittently collected, and the amount collected varies depending on the variety. It is an object of the present invention to provide a method for simply measuring the weight of cotton wool that is sent to a press.

[0006]

SUMMARY OF THE INVENTION To achieve the above object, the present invention is directed to an apparatus for collecting cotton fluff that sequentially transfers cotton fluff from a large number of spinning machines by an air flow, separates it from the carrier air with a fiber press, and accumulates it. In the above, in the main duct for conveyance to the fiber press, a cotton thread detector by a photoelectric tube is provided, each spinning machine is provided with cotton drop suction means, and the accumulated cotton drop weight per unit time by the suction means is measured in advance, and each spinning machine is measured. The cotton drop is sucked at a predetermined time interval, the transferred cotton is confirmed by a cotton detector, and the weight of the cotton drop is measured from the number of times the cotton drop is fed to the fiber press.

[0007]

The weight of cotton litter generated per unit time in the spinning machine is measured in advance, and the weight of cotton litter accumulated during the cotton litter discharge cycle in which the cotton litter is collected from many spinning machines can be predicted. Therefore, the weight of the cotton drop supplied can be measured by measuring the number of times the cotton drop supplied to the fiber press is supplied.

EXAMPLE The figure shows this example. The cotton litter collecting and weighing device 1 is provided with cotton litter suction means B which is provided to face each of a large number of combers A1, A2, A3 ... (Hereinafter, simply referred to as A).
1, B2, B3 ... (hereinafter, simply referred to as B when collectively referred to)
, Branch ducts C1, C2, C3 ... (hereinafter simply referred to as C) for transferring the lint collected by the suction means B, and a main duct D connected to each branch duct C.
And a fiber press F connected to. Switching valves E1, E2, E3, ... (hereinafter simply referred to as E when collectively referred to) are attached to the respective branch ducts C, and a cotton thread detector G is attached to the main duct D in the vicinity of the fiber press F. This cotton detector G is composed of a photoelectric switch, and its outline is shown in FIG. Reference numeral 20 denotes a tubular frame, which is inserted into the main duct D and attached, and is provided with a light projector 22 on one side and a transparent plate 21 on the other side and a light receiver 24 on the other side and a transparent plate 23. 25 and 26
Indicates a support bracket.

The falling cotton sucking means B is schematically shown in FIGS. 2 and 3. The cotton drop sucking means B is provided below the perforated roller 10 provided below a sliver (not shown) to be combed, and below the perforated roller 10.
Saxion head 11 with a length that is almost the entire length of the comb
And a saxion pipe 12 which is located substantially in the center of the machine base and is continuous with the saxion head 11, and the saxion pipe 12 is connected to the branch duct C. The perforated roller 10 constantly rotates, and an intake action is exerted only on the upper half of the perforated roller 10 to adsorb short fibers and the like that fall due to a combing action, and when the porous roller 10 rotates and reaches a lower position, the intake action is blocked, or conversely, compressed air is generated. The short fibers and the like which are jetted and adhered are dropped into the suction head 11 and accumulated.

The switching valve E is sequentially opened and closed by the opening / closing means H at predetermined time intervals and at predetermined time intervals, and the suction force of the fiber press F causes the cotton wool in the suction pipe 12 to move into the fiber press. The transfer is carried out together with the carrier airflow. The transferred cotton is detected by the cotton detector G, and the signal is applied to the control circuit CPU. The control circuit CPU calculates the weight of the cotton drop supplied to the fiber press F from the number of detections, and a specific example will be described below.

The number of combers A1, A2 ... A10 is set to 10 and the flow velocity of the carrier air flow in the main duct D is set to 10 m / s by the suction force of the fiber press F. The distance to the comber A10 farthest from the fiber press F is set to 50 m. The furthest comber A10 in this case
It takes 5 seconds to reach the fiber press F from. Therefore, if the suction is performed for each comb A at a time interval with a slight margin (for example, 7 seconds), there is no overlap. Further, from the experimental results, it is sufficient that the time required for sucking the lint in the suction head 11 of each comb is 6 seconds.

Therefore, the suction time for each of the combers A1 to A10 is measured with a margin of 7 seconds and the stop time between the suction times is 7 seconds. The procedure is shown in FIG.
That is, the cotton drop is continuously sucked during the suction time of 7 seconds, and the cotton passing detector G detects this. However, even if dropped cotton is sent intermittently during that time, it is calculated as once within that time. At this time, the weight of the cotton drop was 1 cycle for each comb (14 in this example).
The amount sent to the fiber press F can be calculated by knowing the amount accumulated in 0 second).

If the cotton drop rate differs depending on the type of raw cotton or on the machine stand of the comber, it is stored in advance and calculated including it. When a predetermined weight of cotton is accumulated in the fiber press F, open the opening / closing valve V at the bottom,
Supply to a carrier (not shown).

Although the above embodiment shows an example in which lint is sequentially sucked for each comb, when there are a large number of combs, a plurality of combs are divided into unit comb groups, and each unit comb group is described above. The cotton wool may be sucked in order as required.

In the above embodiment, the sucking of the cotton wool from the comb is described. However, not only the comber but also other spinning machines are provided with cotton wool sucking means, and the cotton wool accumulated in the sucking means is used as described above. May be sequentially sucked.

[0016]

As described above, according to the present invention, the cotton swab suction means is provided for each spinning machine, and the cotton swab accumulated in each suction means is sequentially sucked through the main duct at predetermined time intervals. As a result, the cotton fluff of each spinning machine is fed separately, and therefore errors due to the mixing of cotton fluff can be prevented. Also, measure the amount of cotton drop accumulated in the suction means in advance,
Since the amount of cotton droppings supplied to the fiber press is measured from the number of cotton droppings sent through the main duct, the measurement is accurate and easy, and the measurement can be automated. .
