Abstract

PURPOSE:To integrate metering hoppers which are conventionally set in each feeder into one and to make the whole device inexpensive, by providing one metering hopper between a great number of fiber feeders and a large number of mixing and blowing machines with putting fiber feed passages between them. CONSTITUTION:The plural fiber feed machines A are set in parallel, connected to the single metering hopper C through each of the fiber feed passage B, respectively, and the hopper is connected to the plural mixing and blowing machine D by the fiber feed means E. The fiber feed machines A are set depending upon the kind of fiber, and equipped with the fiber opening mechanisms a and the feed driving mechanisms b to change high-speed large amount feed to low-speed small amount feed and vice versa. The metering hopper C sends a signal of large amount feed until the metered value reaches about 90% set value, and when it reaches about 90%, the hopper sends a signal of low amount feed. When it reaches 100%, the small amount feed is stopped, and the fiber to be fed is released. The setting regulator can establish a set amount in each fiber feed machine, and operates successively a corresponding fiber feed machine in accordance with a set order.

Description

[Detailed description of the invention] B. Industrial application fields This invention relates to a mixing and batting device for synthetic fiber blend spinning.

BACKGROUND OF THE INVENTION In general, many fabrics are made from yarns made of a mixture of various fibers, including natural fibers and man-made fibers, and in the preparation process for making such yarns, various fibers are mixed in appropriate proportions. Mix M! to mix evenly! A blend batting machine for i-blending is used.

Conventional mixing and batting equipment for synthetic fiber blending is often equipped with a needle quantity hopper for each of the plurality of fiber feeders used for each fiber, and the different types of fibers weighed by each weighing hopper are transferred to a conveyor. etc. were supplied to the cotton mixing machine.

However, the method of equipping each fiber feeder with a weighing hopper is highly accurate and highly labor-saving because the measuring accuracy of the mixing ratio of each fiber has a large effect on the yarn quality and even the quality number of the final product (cloth). As a result, the entire device is expensive, requires a large space, and has high running costs.

In addition, conventional fiber feeding machines use a lattice to open the fibers and feed the fibers, so in recent cases of high-mix, low-volume production, when switching lofts, the previous fibers stick to the lattice. This invention has the disadvantage of requiring a lot of effort to clean and remove. Object of the Invention This invention improves the disadvantages of the conventional device, is inexpensive, takes up a small space, and is easy to work with when changing lofts. The purpose of the present invention is to provide a mixing and batting device for synthetic fiber blending with improved performance.

20 Structure of the Invention This invention includes a fiber opening mechanism and a fiber opening m
A plurality of fiber feeders are equipped with a feed drive mechanism capable of switching between high-speed, large-volume feeding and low-speed, small-volume feeding of fibers, and output a large-volume feed signal until the meter value reaches approximately 90% of the set amount; A single weighing hopper that stops the large quantity supply and issues a small quantity supply signal when it reaches 90%, and stops the small quantity supply and releases the input fiber when it reaches 100%, multiple fiber feeders and a single weighing hopper. a fiber transfer path that connects the fiber feeders, and a setting control device that allows the setting amount to be set for each fiber feeder, and sequentially operates the corresponding fiber feeders in accordance with the set order to perform weighing in the weighing hopper in order; A mixing and batting device for synthetic fiber blending is constituted by a means for conveying the fibers discharged from the weighing hopper to a mixing and batting machine.

In addition, the opening mechanism of the above-mentioned fiber feeder is composed of a bell, one conveyor, and a opening cylinder with needles on the circumference, and as a fiber opening method that does not use a lattice, it can be used when changing the loft in high-mix, low-volume production. This simplifies cleaning work.

(D) shows a mixed batting machine, which is also installed in plural numbers and is connected to a weighing hopper (C) by a fiber transfer means (E). (F) is a setting control device.

The tlIi fiber feeder (A) is equipped with a fiber opening mechanism (a) and a supply drive mechanism (b) that can switch and drive the spread fibers between high-speed, large-volume supply and low-speed, small-volume supply.

The opening mechanism (a) can employ any known force, but for high-mix, low-volume production, a fiber opening mechanism that does not use a lattice is preferred, and an example thereof will be explained with reference to FIG.

In Fig. 4, (1) is a belt conveyor for introducing bulk fibers, and on the end thereof, there is a first belt conveyor having needles (2) on the circumferential surface.
Spreading cylinders (3) and (4) are provided, and first, the first opening cylinder (3) at the bottom scrapes up the lumpy fibers sent by the introduction belt conveyor (1) with a plow (2) on its circumferential surface. The opening cylinder (4) at the top further opens the fibers and scrapes them to the front of the opening chamber (5). A belt conveyor (6) is provided to be inclined upward from 01i,
The fibers opened by the first opening cylinders (3) and (4) are transferred to the second opening cylinder.
, third and fourth opening cylinders (7) (8) (9)-\. That is, the second opening cylinder (7) further opens the fibers sent by the relay belt conveyor (6) with the needles (7a) on the peripheral surface, and the third opening cylinder (8)
The fibers opened by the second opening cylinder (7) are passed through needles (
8a), while further opening the fibers, the fibers are scraped off from the second opening cylinder (7) and sent to the fourth opening cylinder (9), where the fourth opening cylinder (9) is used as the third opening cylinder. Cylinder(
8) is to further spread the spread fibers with the needles (9a) on the peripheral surface and scrape them forward and transfer them, and No. 11511

Cylinder <3) (4) performs coarse opening, and gradually performs fine opening from the second opening cylinder (7) to the third opening cylinder (8) and then to the m4 opening cylinder (9). It's something to go on.

The second to fourth opening cylinders (7), (8), and (9) include:
An arc-shaped bottom plate (lO) is provided at the bottom of the bottom plate to prevent the spread fibers from falling off.

Immediately after the fourth opening cylinder (9), a reservoir chamber (11) for the opened fibers is provided, and a pair of feed rollers (12) (r13) are provided at the bottom of the chamber (11), A feed cylinder (I4) is installed in the feed cylinder (I4) to feed the opened fibers to the fiber transfer path (B).

A phototube or other accumulation amount detector is installed to ensure that a certain amount of spread fiber is always accumulated in the fiber accumulation chamber (11) of the above-mentioned opening mechanism (a), and when the amount falls below a certain amount (lower limit), it is automatically activated. The health converter and opening cylinder are driven, and when a certain amount reaches the upper limit, they are automatically stopped (♀), and the feed speed of the feed rollers (12) (13) and feed cylinder (14) is reduced. Although the case is shown in which the drive can be switched between high-speed large-volume supply and low-speed small-quantity supply, depending on the case, the fiber opening tam, <a>, feed rollers (12) (13), and feed cylinder (I4) may be It is also possible to switch and drive the entire assembly as described above.

Furthermore, the number of three stages and the installation method of the opening cylinders are not limited to those shown in FIG. Any configuration can be adopted as long as it is a system.

In short, by using a fiber opening method that does not use a lattice, it is possible to shorten the work time and labor required to clean and remove the previous fibers at the time of lot cutting/J change in the case of high-mix, low-volume manufacturing. It can be achieved.
