Description

Subject of the invention

The The invention relates to a spinning plant with at least two ring spinning machines with automatic bobbin changing devices, the withdrawn Coils on one on the two longitudinal sides of each of the ring spinning machines place along guided transport and empty pods take from him, and with at least one automatic Dishwasher.

State of the art

Under A master / slave ratio is understood in the art a ratio between a master and at least one Slave connected together in such a way that only the master can access the shared resource while the Slave this only with permission or on instruction by the master can do. The resource is understood very comprehensively, they can be from objects, from values like speeds, from rights how to interfere with the operation of a slave, etc.

A master / slave ratio is, for example, from the DE 101 37 140 C1 in which a ring spinning machine has draw frames with a plurality of draw rolls driven by separate motors. One of the drafting motors is the master, which sets several other drafting motors their speed. The master / slave ratio thus refers here to controlling the speeds of motors. The ratio is limited to the relevant ring spinning machine.

It It is common for each one ring spinning machine over a drivable conveyor belt for full bobbins and empty Sleeves connected to an automatic winder is through which the transport full of bobbins and empty pods between the ring spinning machine and the winder is effected.

General description of the invention

The Invention should solve the problem, the units in particular of winder to enlarge, as a result the rack costs of the machine are distributed over more production sites and the winding machine becomes more economical. A winder with However, more jobs will only be possible through a larger one Number of ring spindles busy to work the winder. But this leads to such high spindle numbers, which in one Ring spinning machine realizes lead to technological problems. In very long machines, the drafting rollers are more troublesome Torsion. The uniform and consistent Applying the spinning stations with suction air to extract waste and for special manufacturing processes such as compaction difficult to fulfill. Also the way to a very long machine from one side to the other is awkward and annoying.

Of the Invention was therefore the task of a multi-spindle winder To connect with ring spindles such that the problems mentioned avoidable are. It solves this task in that the ring spindles be distributed to two separate ring spinning machines whose rolling torsion is controllable, the supply of suction air is ensured and allow a transition from one side to the other.

Of the Transport full bobbins from the ring spinning machines to the winder and empty tubes from the winder to the ring spinning machines However, requires a two-ring spinning machines common transport device, For example, a known per se conveyor belt. Such a conveyor belt can only be operated appropriately if both ring spinning machines to which it is assigned open at the same time, So pull off the full bobbins from the spindles, on the conveyor belt remove, remove empty tubes from the conveyor belt and put on the spindles.

The The invention therefore provides that the doffing process on the two ring spinning machines should take place only when both ring spinning machines the coils (cops) finished. Another condition for this is that all areas of the ring spinning machines, where the doffing process should take place, areas of the conveyor belt compared are the empty pegs for picking up full bobbins and empty pods hold for placing on the spindles.

This However, can wait for the ring spinning machines and the winder to lead.

In Further embodiment of the invention is therefore intended that the two ring spinning machines in such a master / slave ratio stand that only one, the master ring spinning machine a control device for their work organs, by which also the working organs the slave ring spinning machine are controlled. The two ring spinning machines So they run synchronously and finish their coils at the same time.

Specific description of the invention

In the drawing, an embodiment of the invention in plan view of the scheme of a spinning plant with two ring spinning machines 1 and 2 and a winder 3 shown.

The ring spinning machines 1 and 2 show in at least one of their terminal frames 4 . 5 Drive means such as motors for work organs such as drafting, spindles, ringbanks and the like.

The spindle ranges of the ring spinning machines 1 and 2 be through a common conveyor belt 6 looped, set down on the bobbin changing devices, not shown here, which may be of common design, full, deducted from the spindles cops and remove empty sleeves to aufzustecken them on the spindles. The conveyor belt may have individually movable transport plates.

The conveyor belt 6 leads the full cops a converter 7 to, in which the cops removed from the conveyor belt and on a separate, the winder 3 associated transport device 8th implement. This transport device can be provided with individually movable transport plates. In the converter are the plates of the conveyor belt 6 again filled with empty pods.

The conveyor belt 6 the ring spinning machines 1 and 2 also extends over areas of machines that have no spindles. It is therefore only in those areas 9 equipped with transport plates, which are opposite spindle areas when changing bobbins. In the drawing, this position is reproduced.

The production of ring spinning machines 1 and 2 and the rewind capacity of the winder 3 are coordinated so that the winder all full cops from the (four) areas 9 rewind in cheeses and the converter 7 with empty sleeves for loading the conveyor belt 8th can supply until the ring spinning machines again keep bobbins ready for bobbin change. Likewise, the production of the ring spinning machines is designed so that they finished their bobbin structure and are already for bobbin change when they are on the conveyor belt 6 in all areas 9 empty plates and empty pods ready to stand.

The system has a central control device 10 on that over control lines 11 with the machine controls in the end frames 4 . 5 the ring spinning machines 1 and 2 , via a control line 12 a resolver 13 on the conveyor belt 6 and a control line 14 with the converter 7 connected is. The resolver detects the position of the conveyor belt on its circulation around the ring spinning machines and generates a signal when the position shown is reached, so if all equipped with spindles areas of the ring spinning machines are facing areas of the conveyor belt, which allow the bobbin changing operation.

Each of the machine controls of the ring spinning machines 1 and 2 report the completion of the cop structure and their readiness for the bobbin exchange process via a control line 11 to the control device 10 , The resolver 13 detects the position of the conveyor belt 6 and directs via a control line 12 a signal to the control device 10 when the position is reached, in all the spindle areas of the ring spinning machines areas 9 facing the conveyor belt, can be done on the discontinuation of cops and the removal of empty tubes.

When these two signals are present, the controller causes 10 by actuating signals via the control lines 11 to the machine controls the ring spinning machines the common change process and a signal to the converter 7 in that, during the change process, it does not carry out a transformation which would change the position of the conveyor belt.

The two ring spinning machines 1 and 2 work independently. The finishing of the cop assembly and its readiness for the bobbin changing operation occur at different times, even if the operating parameters of the machines are set consistently. This leads to waiting times with standstill of the ring spinning machines and the winder occur.

To avoid this, is in a further embodiment of the invention 2 provided, the two ring spinning machines 1 and 2 in a master / slave relationship to each other. For this purpose, it is provided that only one of the ring spinning machines, in the example shown, the master ring spinning machine 1 equipped with a machine control of their work organs, which are also the working organs of the controlless Slaven ring spinning machine 2 via a control line 15 with controls. This ensures that the working organs of both ring spinning machines run synchronously and both machines achieve the completion of Kopsaufbaues and their willingness to bobbin change operation simultaneously. Waiting times are avoided accordingly.

In this embodiment, the resolver conducts 13 the position of the conveyor belt 6 via a control line 16 to the machine control in the final frame 4 the master ring spinning machine 1 and via a control line 17 to the converter 7 further. In the machine control of the master ring spinning machine, this signal then triggers the bobbin changing process on both ring spinning machines and in the converter 7 it triggers a blockage of the same, so that it does not implement during the bobbin changing process, in the course of which the conveyor belt 6 would be moved.

Also the winder 3 can via a control line 18 with the converter 7 be connected, via which the activity of the converter is set when the winder has reeled all held Kose and must wait for new, resulting from a bobbin change process cops.

After the bobbin changing process, both the ring spinning machines take 1 and 2 and the translator resume their activity.

The Spinning plant shown can also in both embodiments be equipped with more than two ring spinning machines. The invention is also not the illustrated and described embodiment of the machines, the converter and the winder, it can also other working machines are used. Likewise, the connection the working machines through the controls to special conditions adaptable without departing from the scope of the invention.
