Description
DEVICE FOR METERING POWDER, GRAINED OR MICROPEARL DYEING
MATERIALS
DESCRIPTION
This invention relates to a device for metering powder, granulated or micropearl dyeing materials, especially for the textile, 1=arming and paper industry.
A devicES to collect and distribute powder material is known from the document DE-U-9 014 270. This, in the version illustrated in Figures 1-3, includes a plate with several holes through which the material passes by means of a collecting device with a pa7_let rotating round a vertical shaft, which is moved by means of a relative driving element. A plate beneath the above mentioned, perforated plate allows the material sifted in this way to be collected, and a scythe-shaped blade, which is operated by means of said vertical shaft, conveys the collected material into a central outgoing duct.
But this device does not provide for the control of the size of the grains of the sifted material and, furthermore, it does not allow the quick adjustment of the flow rate of the treated material; this highly reduced the device's elasticity degree and limits its employment to the applications for which it is not necessary to quickly change the quantity of the worked material, for example the transfer of material from a silo to another or its package. From the same document, a device to collect the granulated material is also known, which, in the version illustrated in Figures 4-6, is provided with several plane elements, which are moved horizontally and alternately in the two directions, and which convey the material to be treated into the relative diagonal slits or into relative holes on a plate. For the control of the size of the grains of the worked material, a second perforated plate is positioned below the first one in such a way that the holes or the slits of the two plates correspond either exactly or only partially.
But this device also can not guarantee the necessary degree of elasticity for those applications which continuously require quick changes of the flow rate of the material outgoing from the device.
The main aim of this invention is to elimate the above mentioned disadvantages.
According to the invention, there is provided a device for metering powder, granulated or micropearl material, especially dyeing material, and including a container for collecting the dyeing material to be treated, supplied by a store through an input tube; a sieve mounted fixed on the base of the container with a scraper above rotating by means of an electric motor with shaft for the compaction and the ejection of the dyeing material; a compass-type shutter, mounted below the sieve for metering the dyeing material outgoing from the container which is characterized by the fact that the said container is provided with an upper chamber connected to it by means of a central hopper with vertical axis and connected to an external aspirator by means of a tube provided with a filter; by the fact that the said sieve is of the mesh type and that the said scraper rotates with adjustable speed; and by the fact that the device is provided with: a precision balance for weighing the dyeing material going through the port of the shutter; an electronic computer for checking and controlling the rotation speed of the scraper, the weighing value of the balance and at least one of the opening and closing of the shutter.
The advantages which result from the invention essentially consist in the fact that is possible to adjust the quantity of the worked dyeing material continuously, quickly and with high precision, even if in very fine powder form and with weight variation from a thousandth to a hundredth of a gram; and that it is possible to assure a high degree of reliability even after a long working period.
These and other advantages and characteristics of the invention will be better understood by any skilled person in this field thanks to the following description and the accompanying drawing, given as a practical example of the invention, but not to be considered in a restrictive sense, in which the only figure is the longitudinal section view of a device according to the invention.
Reduced to its essential structure and referring to I the Figure of the accompanying drawing, a device for metering the powder, granulated or micropearl dyeing material includes:
- a container (7.) for collecting the dyeing material to be treated, which is supplied from a store through an input tube (8);
- a mesh-sieve (5) mounted fixed at the base of the container (1.) with an upper scraper (2) rotating by means of an electric motor (4) with shaft (3) for .
the compaction and the ejection of the dyeing material;
- a compass-type shutter (6), mounted below the sieve (5) for metering the dyeing material outgoing from the container (1.);
- a precision balance (20) for weighing the dyeing material going through the port of the shutter (6);
- an electronic computer (30) for checking and controlling the rotation speed of the scraper (2), the opening of the shutter (6) and the weighing value of the balance (20).
More particularly, the said collecting device is provided with a upper chamber (9) connected to it by means of a central hopper (1.0) with vertical axis and further connected to an external aspirator (which is not represented in the drawing), by means of a tube (7) provided with a filter (1~.), in such a way to generate a decompression in the container (~.) and to favour the separation and the fall of the particles which constitute the dyeing material.
Another advantage, according to the invention, is that the said computer (30) can be programmed in order to allow the most wide variation of the quantity and/or of the dimensions, that is the metering, of the particles of dyeing material treated by the device, according to the contingent needs of the working sections which use the dyeing material.
The operation of the device is the following.
the dyeing material which has been put into the container (1) through the input tube (8) is accurately subdivided into its particles by the air stream created by the aspirator, then they fall to the bottom, where the scraper (2) compresses them and conveys them through the meshes of the sieve (5). The adjustment of the quantity of dyeing material outgoing from the container (1) is carried out either by means of the shutter (6), the more or less opening of which is controlled by the balance (20) according to the weighing that it must carry out at any one time, or by adjusting the rotation speed of the scraper (2) in order to compress a bigger or smaller quantity of dyeing material through the holes of the sieve (5). The said adjustment is controlled by the computer (30) which in turn is informed by a suitable control program.

According to the invention, there is provided a device for metering powder, granulated or micropearl material, especially dyeing material, and including a container for collecting the dyeing material to be treated, supplied by a store through an input tube; a sieve mounted fixed on the base of the container with a scraper above rotating by means of an electric motor with shaft for the compaction and the ejection of the dyeing material; a compass-type shutter, mounted below the sieve for metering the dyeing material outgoing from the container which is characterized by the fact that the said container is provided with an upper chamber connected to it by means of a central hopper with vertical axis and connected to an external aspirator by means of a tube provided with a filter; by the fact that the said sieve is of the mesh type and that the said scraper rotates with adjustable speed; and by the fact that the device is provided with: a precision balance for weighing the dyeing material going through the port of the shutter; an electronic computer for checking and controlling the rotation speed of the scraper, the weighing value of the balance and at least one of the opening and closing of the shutter.
The advantages which result from the invention essentially consist in the fact that is possible to adjust the quantity of the worked dyeing material continuously, quickly and with high precision, even if in very fine powder form and with weight variation from a thousandth to a hundredth of a gram; and that it is possible to assure a high degree of reliability even after a long working period.
These and other advantages and characteristics of the invention will be better understood by any skilled person in this field thanks to the following description and the accompanying drawing, given as a practical example of the invention, but not to be considered in a restrictive sense, in which the only figure is the longitudinal section view of a device according to the invention.
Reduced to its essential structure and referring to I the Figure of the accompanying drawing, a device for metering the powder, granulated or micropearl dyeing material includes:
- a container (7.) for collecting the dyeing material to be treated, which is supplied from a store through an input tube (8);
- a mesh-sieve (5) mounted fixed at the base of the container (1.) with an upper scraper (2) rotating by means of an electric motor (4) with shaft (3) for .
the compaction and the ejection of the dyeing material;
- a compass-type shutter (6), mounted below the sieve (5) for metering the dyeing material outgoing from the container (1.);
- a precision balance (20) for weighing the dyeing material going through the port of the shutter (6);
- an electronic computer (30) for checking and controlling the rotation speed of the scraper (2), the opening of the shutter (6) and the weighing value of the balance (20).
More particularly, the said collecting device is provided with a upper chamber (9) connected to it by means of a central hopper (1.0) with vertical axis and further connected to an external aspirator (which is not represented in the drawing), by means of a tube (7) provided with a filter (1~.), in such a way to generate a decompression in the container (~.) and to favour the separation and the fall of the particles which constitute the dyeing material.
Another advantage, according to the invention, is that the said computer (30) can be programmed in order to allow the most wide variation of the quantity and/or of the dimensions, that is the metering, of the particles of dyeing material treated by the device, according to the contingent needs of the working sections which use the dyeing material.
The operation of the device is the following.
H, ~ ~ '~ ~ ~ ;_;
the dyeing material which has been put into the container (1) through the input tube (8) is accurately subdlvidacJ into lts parl;leJes by I;I~e alr stream created by the aspirator, they then fall to the bottom, where the scraper (2) compresses them and conveys them through the meshes of the sieve (5). The adjustment of the quantity of dyeing material outgoing from the container (l.) is carried out either by means of the shutter (6), the more or less opening of which is controlled by the balance (20) according to the weighing that it must carry out at any one time, or by adjusting the rotation speed of the scraper (2) in order to compress a bigger or smaller quantity of dyeing material through the holes of the sieve (5). The said ad,justement is controlled by the computer (30) which in turn is informed by a suitable control program.
