Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is directed to a cotton mixing machine that scrapes small raw cotton lumps from a rectangular parallelepiped-shaped hard raw cotton lump, that is, an open bale raw cotton after being unpacked in a spinning factory. This invention relates to an automatic raw cotton supply device for supplying raw cotton by pneumatic transportation.

[Conventional technology]

In general, when opening raw cotton using an automatic raw cotton supply device that scrapes small raw cotton clumps from open bales of raw cotton and supplies them to a mixing and batting machine, a device such as opening teeth or a beater that bites into the raw cotton and separates the cotton clumps is used. 2. Description of the Related Art A hale opener is known in which raw cotton is scraped off by mechanical means using a rotary body provided with protrusions, and the raw cotton is air-feeded through an air-feeding duct.

The hale opener, which is particularly frequently used, has one oatbus per column, and the tufts, which are opened by scraping the surface of the raw cotton with the 8-column opener, are air-fed to the cotton blending line for the next process. The mixed cotton was automatically supplied to the cotton mixing machine.

[Problem to be solved by the invention]

In this conventional opener opening section, the operation is as shown in Fig. 8 (a).
), and the operation is forced into a supply disruption period t3, which is a raw cotton supply failure time t2 for loading open bales of raw cotton and a raw material supply shortage due to the raw cotton surface or time t. Therefore, in order to reduce the work time loss of loading open bales of raw cotton when scraping tufts and the time loss of smoothing the raw cotton surface, the rotary table method requires the opener to be rotated to change the setting position, and the two columns to be Attempts have been made to operate each machine alternately as shown in Figure 8 (b), and in a system in which the openers run, the openers are alternately rotated around groups of open bales arranged in two rows in the running direction. Although I use a multi-mixer, it still takes t to smooth the surface of the raw cotton.

In addition to being forced to operate when there is a shortage of raw cotton supply, the installation area is large, wasting space, and equipment is expensive.In addition, the initial cost is relatively high and operation management is complicated, resulting in a decline in product quality and production volume. This was a problem because it was likely to have a negative impact on

In particular, in conventional mass production factories, attempts have been made to mix not only one type of raw cotton from the open bales placed in the opening section but two or more types, but there is a limit to the types, and various changes have been made. In order to carry out this method, not only a large number of devices were required, but also the mixed cotton line was complicated, the length of the duct was inevitably long, and the air transportation equipment was also enormous, making it uneconomical.

The present invention aims to accurately eliminate these conventional drawbacks, and also appropriately eliminates the time loss during raw cotton loading work and raw cotton surface smoothing operation, and opens multiple raw cottons simultaneously on a machine. It can be processed efficiently and safely, and can be opened in a way that saves space and reduces initial costs. Fine, uniform tufts can be produced at all times, and a good blended state can be obtained, greatly improving product quality. The object of the present invention is to provide an automatic raw cotton feeding device that can improve the quality of raw cotton and improve the production volume.

[Means to solve the problem]

The present invention provides a table on which open bales of raw cotton can be placed in a plurality of rows, a means for contacting the plurality of rows of open bales of raw cotton and scraping the surface of the raw cotton, and a means for scraping the surface of the raw cotton and transferring the scraped tufts to mixed batting cotton in the next process. An automatic raw cotton supply device in which an opener having a hood connected to a duct that can be air-fed to the machine is arranged along the table with a column, and the open bale raw cotton on the table and the opener are movably arranged opposite each other in a relative relationship. , the column is equipped with an air feed line for the scraped tuft to a mixed batting machine,
An automatic raw cotton feeding device characterized by having a structure in which a plurality of openers connected to each line are arranged in a vertically movable manner to open multiple groups of raw cotton at the same time and feed the cotton to the same or separate cotton mixing machines. It is.

[For production]

In the raw cotton opening and supplying apparatus of the present invention, the opening section of the opener A that moves up and down in the column B scrapes off the upper surface fibers of the open raw cotton, and the scraped tufts are passed through the hood 4 and the duct 3 to the next process. The open bale raw cotton F is placed on a table C placed close to the column B, and is moved directly below the opener by a motor, and the opener is moved up and down across the column. The tufts are efficiently scraped off by the opener teeth 1 of the rotating opener roller 2 at A. The fine, uniform fluff scraped from the surface of the open bale raw cotton F in this opening section is then distributed through the duct 3 of the mixed batting line from a cotton feed switching mechanism, for example, a distributor G, and then distributed to the mixed batting machine E. The raw cotton is pneumatically transported to the next process equipment, but multiple openers A, A, etc. in one column B are operated separately to simultaneously open multiple open bale raw cotton groups, and one opener is operated. During production, it is possible to stop the operation of the other opener and load the raw cotton onto table C. Continuous operation is possible through this opener lamp operation, and it is also possible to operate multiple openers and multiple tables at any time, making it possible to load raw cotton onto table C. The amount of cotton can be greatly increased, and there is no loss in raw cotton loading time or loss in smoothing the raw cotton surface during feeding to each mixed cotton machine line, and at the same time automatic feeding can be performed, which reduces the size of the tuft by half and allows for fine opening. The blended state of the cotton can also be improved by simultaneously supplying tufts from a plurality of raw cottons.

〔Example〕

An embodiment of the present invention will be described with reference to FIGS. 1 to 4. An opener roller 2 having opener teeth 1 for scraping the surface of open bale raw cotton F is rotatably provided, and the scraping tact is a hood 4 connected to a duct 3 that can be fed and connected to a mixed batting machine E for the next process; and a presser guide plate 5 that covers the lower surface of the opener roller 2 and regulates the amount of protrusion of the opener teeth 1.
In an automatic raw cotton supply device, an opener A, which is equipped with an opener frame 6 and a pressure roller 7, is arranged in a column B so as to be able to move up and down. The opener A, which straddles and contacts the bale raw cotton F and scrapes the surface of the raw cotton, sends the tufts scraped off by the opener roller 2 to the next step, the mixed batting machine E, along with the table C with the column B. a tuft air feed line D to one or more mixed cotton machines is provided in the column B so that the open bale raw cotton F on the table C and the opener A are movably arranged opposite each other in a relative relationship; A plurality of openers 8 connected to the lines are arranged to be movable up and down, and a plurality of open bale raw cotton groups F are simultaneously opened and fed to the same or separate cotton mixing machine E.

In this case, the table C for placing open bales of raw cotton is a rotatable or reciprocating table such as a turntable or a traveling conveyor, and multiple tables are arranged in close proximity, for example, in parallel or in a circle, and each table C is A column B equipped with a plurality of openers A that can be raised and lowered to open the surface of each open bale of raw cotton F is installed between the tables C2C, and 2
Column B, which is equipped with the above-mentioned plurality of openers, for example 2 openers or 3 openers A, etc., in a vertically movable manner rotates and/or
Alternatively, an automatic raw cotton supply device may be provided between the tables c and c so as to be reciprocally movable.

If the table C for placing open bales of raw cotton is a turntable as shown in Fig. 3-4, a plurality of turntables are arranged in parallel or concentrically, with each turntable C2C...
・One column B is fixedly equipped with openers A, A, etc. facing above, but as shown in the example in Fig. 5,
A column B equipped with a plurality of openers A is rotatably installed at the center of a fixed table C for placing open bales of raw cotton, and each opener A is mounted on the open bales of raw cotton F on the table C. It is also possible to use an automatic raw cotton supply device that rotates the fibers and opens the fibers from the upper surface thereof.

In these cases, a multi-pass distributor G is interposed on the line D that can air-feed the tufts scraped by the opener A to the next step, the mixed batting machine E. You can also choose to feed the cotton to cotton machine E...

In addition, the open bale raw cotton F in the opening section to the opener is moved to the oven frame directly below the opener A by rotating a turntable C placed close to the column B, which is rotated by a motor, and moved up and down to the column B. The tufts are efficiently scraped off by the opener teeth 1 of the rotary opener roller 2 in B, and the tufts are sucked into the duct 3 through the hood 4. It is now air-fed to a device such as a hopper mixer. In the example shown in FIG. 5, a plurality of opener frames 6 are arranged in a radial manner so that the fibers can be opened by a rotary tower, but the turntable C may be rotated by a fixed tower. The example in FIG. 6 is a cotton feeding device in which column B can be moved horizontally, with openers A protruding from both sides,
A is moved onto the open bale raw cotton F and F group arranged in parallel and opened at the same time.

In this case, column B reciprocates, and when openers A protruding from column B are used to scrape the upper surfaces of the two rows of left and right raw cotton bales, if the heights of the upper surfaces of the raw cotton bales are different, opener A is activated by the position sensor. It can be raised and lowered to allow scraping from the top surface.

In the example in Fig. 6, instead of a self-propelled or traveling type in which column B moves back and forth along a row of open bale raw cotton arranged in a straight line, column B is fixed and open bale raw cotton F is placed. The table C may be of a type that moves back and forth as a conveyor. In addition, for raw cotton of almost the same shape, such as open bales of synthetic fiber, it is possible to open several bales to more than ten bales of raw cotton at the same time as shown in the example shown, or it is possible to open raw cotton of different varieties at the same time. It is also possible to open the fibers for each lot.

Furthermore, as shown in FIGS. 4 to 6, it is possible to expect an improvement in the cotton blending rate by simultaneously applying a plurality of fiber opening parts to one blended cotton.

In addition, as shown in the example in Fig. 2, a type without blowing off the tufts may be used instead of the opener roller 2 by using an air jet from an air jet nozzle. It is also effective to separate contaminants by utilizing the speed difference between them and dust, metal chips, etc., and collect and remove contaminants in a suction pocket with a filter provided at the bottom of the hopper.

Furthermore, the open bale raw cotton F is placed on a turntable C disposed close to the column B, and is rotationally driven by a motor, so that it can be effectively applied to a traveling conveyor system instead of the rotary table system.

1 with 2 openers, 1 and 2, as in the example in Figure 3a.
When feeding tufts from a column and two tables to one mixed cotton machine E, the operations of the floor 1 opener and the floor 2 opener are alternated so as to obtain the predetermined production amount of the mixed cotton machine E as shown in Figure 7a. every 1 dosof (T), and the overramp operation time (t
If 2) is interposed at the time of switching and continuous operation is performed, a predetermined production amount can be efficiently achieved.

In addition, as shown in the example in Fig. 3a, 1 lkl and two openers on floor 2 are operated at the same time to obtain a predetermined production amount of the mixed batting machine.
Fig. 7 (as shown in bl, overlap operation time (t2)
By obtaining the raw cotton loading time (to) alternately for each table C before the table C, it is possible to easily eliminate time loss during raw cotton loading.

In the example in Fig. 3 fb1, tufts are supplied from 1 column, 2 openers, and 2 tables to 2 mixed cotton machines, and the 7th q.
As shown in c, the production volume is the sum of the prescribed production volume of the 1st mixed cotton batting machine and the prescribed production volume of the 2nd mixed batting machine, and the overramp operation time (t2) is calculated when switching between the 1st opener and the 2nd opener. In combination, it is possible to perform continuous opening processing at all times, greatly increasing production volume.As shown in the example in Figure 4, one column
Even when supplying from three openers and three tables, continuous operation is possible through overramp operation in the same way as in the previous example to obtain a predetermined production amount. Additionally, it becomes possible to operate multiple openers and multiple tables at all times while covering the raw cotton loading time.

In any case, by applying Multi Distributor G, etc., it becomes possible to simultaneously supply cotton to multiple mixed batting machines without loss of loading time or break-in operation loss, and moreover, multiple opener tables can be operated at all times. By this,
In addition to being able to change the size of the tuft by half a year (finely), multiple tables of raw cotton and tufts are supplied at the same time, making it easier to improve the quality of the cotton blend.

[Effects of the Invention] The present invention has a column equipped with a pneumatic feeding line for the scraped tuft to the mixed cotton mixing machine, and a plurality of openers connected to the line are arranged to be able to move up and down, thereby opening a plurality of groups of raw cotton at the same time. By adopting a configuration in which the cotton is woven and sent to the same or separate cotton mixing machine, time loss during loading of raw cotton and smoothing of the raw cotton surface can be appropriately eliminated, and multiple raw cotton can be processed on one machine. At the same time, the fibers can be opened in a way that allows for efficient and safe processing, as well as space savings and initial cost reductions, allowing for the production of fine, uniform tufts at all times, and the ability to obtain good mixed-knocking conditions. Even in the cotton opening-mixing and batting process, it is possible to quickly and safely switch between different types of raw cotton without requiring a large quantity of equipment, making it easy to simplify and shorten the blending and batting line. It is easy to operate, has advantages in terms of maintenance and safety, and has the practical effect of greatly improving product quality and production volume.
