Abstract

A multiple scouring-fulling machine, comprising a single common tank (1) with perforated dividing partitions (3) allowing the intercommunication between the tank sections (5) formed by said partitions, and independently operating heads (12) overhanging each tank section (5).

Description

The present invention relates to a multiple bleaching-flooring machine for fabrics which has special advantages and performances that will become evident upon reading the following description.

A bleaching-flooring machine is offered. during its operation, the phases of:

1) pre-wash;

2) percentage reduction of water in the tissue;

3) introduction of flooring agents (soap, etc.);

4) flooring;

5) washing.

The bleaching-flooring machine must be adjusted according to the operations required by the action of the inlet or pad phases (which is a function of the percentage of reduction in texture), the pressure of the transfer cylinders and the cover (which it is a function of the pei; warp reduction percentage), all this to originate the flooring of wool or mixed wool fabric.

They are known:

- simple flooring machines (with a single tank and only one row, that is to say a single fabric passed through the head with one or several turns):

- washing floor machine (also with a single tank and only one passage)

- washing machine with two rows (with a single tank, two rows, and a single drive for the two pairs of pressure cylinders):

- four-row flooring machines, with two coaxial axes, with the respective drives (with a single tank and four individual rows);

- paving machine with four or six rows (with a single tank, four or six individual rows and only a drive with a rigid axis).

In some cases, multiple washing-floor machines include means to control individual rows by adjusting pads or covers,

In the case of multiple machines, when the fabric of a row reaches earlier than the other fabrics to be finished. percentage of pre-determined work in length and / or washing, due to the different characteristics of the thread or the length of the row, the fabric must be removed and washed in a second step. Otherwise, keeping the operating pressure of the cylinders stable, even expanding the covers separately and opening the cushions, it will be difficult to correctly control the shrinkage percentages. In conclusion, it is difficult to achieve uniform results in the various tissues treated simultaneously.

Achieving a more uniform final standardized weight is only possible by actually controlling each individual row, thus also ensuring regular lifting and other finishing operations after flooring.

Some types of fabrics require a power that is higher than that applied individually to multiple machines, and powers that are higher than those actually required must be provided. These extra powers are also required because of the possible occurrence of simultaneous absorption tips during the passage of seams or others.

length of the axles of the cylinders causes structural and duration problems, which are sometimes difficult to solve.

Very long shafts without intermediate bearings must be oversized.

On multiple machines it is practically impossible to use systems to control the percentage of work

in the longitudinal direction, since the sensors, mounted to detect the passage of seams, create virtually irremovable interference.

On multiple machines, it is practically impossible to work with fabrics with substantial differences in weight in grams, because of the differences in thickness that these fabrics have when they pass through the cellars.

The present invention overcomes the aforementioned disadvantages, although it provides a machine that is capable of working in a manner similar to the previously mentioned multiple machines.

A multiple floor bleaching machine according to the model object of the present invention comprises essentially a single common tank, with perforated separators allowing intercommunication between the tank sections formed by said separators, including, in addition, independent operating heads , each over the respective section of the tank.

In practice, a platform overlapping the sections of the tank, which supports said heads, may be useful.

Each of these heads is advantageously operated by a hydraulic motor. A common hydraulic system that powers the hydraulic motors of the various heads can also be provided.

The present invention will be better understood by the following description and the accompanying drawings, which show a practical, non-limiting example of the same invention. In the drawings:

Fig. 1 shows a schematic side view. in the intermediate section of the multiple machine according to the present invention; and

Fig. 2 shows a view esquemética, ⁴ par- tially longitudinally sectioned.

According to what is shown in the attached drawing, the number 1 indicates a common tank for the mu machine?

Case 44466 tipla, object of the present invention which is subdivided by separators 3 into a plurality of separate sections 5. Separators 3 are perforated in the form of a grid, that is, ofe. there is a substantial capacity for communication between the various sections 5 of the tank, which however remains common and unique. Developing above the tank 1 is a platform 7, which can be made of any suitable material and extends along the entire front of the tank, being supported at the ends by means of support 9. Placed on the platform 7 individual heads 12 are essentially illustrated, each of which is provided with the ellips. typical features of flooring machines, in particular with pressure cylinders 14, with the so-called pads or faces 16 for transversely compressing the fabric T at the entrance between the two pressure cylinders 14, and with the so-called cover 18, which compresses the fabric at the exit of cylinders 14. 0 te. eido T is passed through several times, with a view to forming the so-called row, passing through the head assembly 12 and diving again into the tank in section 5, which is associated with each of the said heads. The number 14A indicates the means for controlling the pressure of the pressure cylinders 14, while the means for regulating the pads 16, the cover 18 and the pressure cylinder are omitted for the sake of clarity. All the adjustment means for each head 12 are individual and independent of each other. Each head 12 is typically driven by a hydraulic motor, indicated as 20 in the drawing, which can be installed in a sus position. he thinks, possibly having two drive belts for the pressure cylinders 14. The hydraulic motors 20 of each head 12 can all be powered by a single central unit 24, consisting at least of a hydraulic pump with sufficient capacity to ensure the operation of all motors installed in the individual heads 12.

The heads 12 are not provided with connections, es. especially rigid connections with each other, but are not

merely placed on platform 7, which is relatively rigid, but whose possible deflections do not affect said individual and adjacent heads 12.

With the separate tank represented by each section 5 for each individual head 12, the latter can bore. operate independently of the others without the mass of the T-line of tissue within the tank section affecting the functioning of the heads 12 within the adjacent sections 5, as long as required. the possibility of a safe exchange of liquid between one section of tank 1 and another, common to all heads.

The main differences of the machine object of the present invention, when compared with the known machines. mentioned above, are as follows:

- The common storage tank, with perforated separators, allows the common entry of water during the pod and prevents the formation of fibers, knots and overlaps between adjacent rows in the event of the stop of a row during the flooring;

- The individual drive for each pair of cylinders (or called channels), obtained by a hydraulic motor. self-contained co, or even, by an electric motor for each individual and complete flooring group.

It is thus achieved among other things:

A) have perfect, absolutely individual control of the technological cycle of the individual rows, that is, fabrics, which can also be of different materials;

B) the possibility of achieving uniform standardized weights:

C) the possibility of installing and exploiting sufficient powers for each absorption tip of each head, without resorting to very high installed powers:

D) the elimination of any structural problem related to the axes:

E) no difference between the pressures actually applied to the rows:

F) the possibility to apply in an objective way, an automatic control in the reduction of the warp of each fabric

The flooring unit or a flooring head is intended to be a constructive set, including the groups indispensable to achieve the flooring effect, that is: adjustable pads, cylinders for transferring and compressing the fabric with the appropriate drive; adjustable floor coverings.

The known simple flooring machines, the three groups mentioned are connected or are in solidarity with the external structure of the machine, never having been provided before in a single set.

This was achieved by the multiple floor bleaching machine object of the present invention which, in conclusion:

1) it is a machine made of two or more complete and self-contained flooring heads, inserted in a storage tank containing one or more perforated separators;

2) complete floors, which can be programmed manually or automatically with identical or different operating parameters (speed, pressure, etc.);

3) it is a machine made of two or more flooring heads, in each of which the operating parameters can be changed or replaced either manually or automatically during operation;

4) it is a machine with a common storage tank and with one or more perforated separators, which allows operation without interference between close rows in the event of stopping, and without intercommunication in the presence of water during the washing phase;

5) it is a machine that, being made of two or more independent heads, allows the application of an automatic control of the percentage of reduction in the fabric length;
