JPH0598525A - Flyer - Google Patents

Abstract

PURPOSE: To provide a flyer which is divided to independently functioning plural blocks, provides the function units of the same kinds with independently controllable discrete drives in the respective blocks, connects all the drives to a control computer and is capable of interrupting production by avoiding the shutdown of the entire part. CONSTITUTION: The flyer having an eccentric drive system is divided to the mutually independently functioning plural blocks S1 to Sn. The discrete drives A11 to An6 for a bobbin wheel SWP, for stretching rolls SW1 to SW3, for a spinning wing SF and for a sliver bobbin SP are installed in the respective blocks S1 to Sn. These drives A11 to An6 are respectively independently controllable in association with the other drives of the corresponding blocks. All the drives A11 to An6 are connected to the host control computer L via lower computers B1 to Bn, by which the productivity of the flyer is improved while the shutdown of the entire part of the flyer is averted at the time of the interruption of the production.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a fryer equipped with an eccentric drive system.

[0002]

2. Description of the Prior Art From East German Patent Specification No. 217,832, a fryer equipped with an eccentric drive system is known. A separate adjustable drive is provided for each functional unit that performs a respective spinning function. These functional units are involved in the movement of bobbin wheels, spinning wings and draw rolls. The number of revolutions of these units is continuously adjustable and is controlled according to quality parameters. The adjustment value is set by a microcomputer.

[0003]

This method presents a few advantages with regard to the saving of mechanical transfer elements and adjusting elements, but, like the conventional devices, it causes disturbances in the production process, such as cutting of sliver or bands. There is a drawback that the entire fryer device must be stopped when replacing the bobbin. Therefore, there is a limit to the improvement in productivity. The problem to be solved by the present invention is to avoid the stoppage of the entire fryer device as much as possible during production interruption.

[0004]

According to the present invention, the above-mentioned problem is solved in that the fryer is divided into a plurality of sections that function independently of each other, and in each section, a separate drive is provided for each functional unit of the same type. These drives can be controlled independently of each other in relation to the other drives in the corresponding compartment, and all drives are connected to the host control computer in each compartment. It is solved by preparing. Other essential features of the invention are set forth in the appended claims 2 and 3.

[0005]

The present invention will be described below with reference to the embodiments shown in the drawings, but the present invention is not limited to these embodiments.

Although not shown per se, the fryer of the invention is divided into n compartments S1 to Sn, which compartments are completely mechanically separated and interconnected only by a common frame assembly. Each section S1 to Sn contains 12 or a multiple thereof. Each section S1 to S
In n, separate drives are attached to the same type of functional units. For example, in the section S1, drives A11-A16 are provided. In this case, an asynchronous motor with adjustable frequency has proved effective.

The drive A11 drives the spinning wings SF of the section S1, the drive A12 drives the bobbin SP,
The drive A13 drives the bobbin wheel SPW,
One bobbin wheel SPW exists in each of the sections S1 to Sn as one of the functional elements. Drive A14
To A16 are first to third stretching rolls SW1 to SW, respectively.
Connected to 3.

All the drives A11 to A16 are connected to the subordinate computer B1. The sections S2 to Sn have the same configuration. All the subordinate computers B1 to Bn in the sections S1 to Sn are connected to the control computer L. The above structure, depending on the requirements of the fryer device,
It can be easily adapted to the number of functional units driven.

During operation of the fryer device, the sub-computers B1 to Bn calculate the required values for the spinning technology and transfer the adjustment values derived therefrom. In this way, a tuning control of functional units which are no longer interconnected by mechanical actuators is implemented. The subordinate computers B1 to Bn detect the partition S1 by the corresponding sensor.
˜Sn functional units are detected at the beginning and end of the operation of the spinning structure, the cause of the necessary process modifications, eg irregular feeds of the sliver, process interruptions such as band or sliver ruptures, and the like. Generate the necessary adjustment values consistent with the principle. Further, these following computers cause the process to be restarted after the process is interrupted.

The operation of the subordinate computers B1-Bn is coordinated by the control computer L. Spinning technical data required for each spinning process are externally added to this control computer. The control computer L transfers these data to the subordinate computers B1-Bn.
Worker modifications and interventions are also performed through the control computer L. It is possible to give a higher authority to the control computer L. In that case, this control computer integrates the functions of the subordinate computers B1-Bn.

[0011]

The invention shows the advantage that the respective compartments of the fryer can be activated automatically to the maximum extent possible. These partitions do not affect each other, but are connected to each other through the control computer. Therefore, the production stoppage in one compartment does not adversely affect the other compartment. The other partitions do not need to be stopped. Flyer productivity is improved. Less mechanical assembly is installed and functional units stop section by section during production shutdowns, reducing energy losses. The movement transfer path between the drive and the respective functional unit is shortened, so that the movement transfer is accurate, which leads to an accurate flyer structure. Due to the independence of each compartment, the adjustment of the spinning wings between compartments is distributed stochastically so that a smooth run of the entire fryer is recorded.
