Title of the invention

Process aura loading of twisting machines

Field of application of the invention

The invention relates to a method for loading processing machines, In particular from Schnellverseilmascbinen, using lifting devices and grippers.

Characteristics of the known technical solutions

The feeding of the stranding machines, especially the Schnellverse ilni machines with tubular rotors, has so far mostly been done with electric trains that can be moved over the machines, or by means of loading aids, which are supplied as supplies to the packaging machines belong. The disadvantage of these loading aids is the large amount of manual work involved and the relatively long loading time and the high risk of accidents. Through the DD-PS 66 811 a Bescbickeinricbtung has become known, which consists of a There is a movable gripping device in the vertical and horizontal plane, which is provided with pressure bolts pretensioned by springs is equipped, which open the bobbin storage when lowering the gripping device. The gripping device takes the empty bobbin out of the bobbin carrier and moves on. above. Then the gripping device swivels outwards and follows below. The empty bobbin is set down here, a new bobbin is picked up and moved upwards. The gripping device swivels over the stranding machine again and then goes down. The full bobbin is lowered over the bobbin frame. When the pressure bolts are placed, the pinolan open the bobbin storage and the bobbin is placed in receiving pockets. The tong arms of the gripping device open and

are held in this position by a locking pin. The gripping device is then moved upwards again. At the same time, the coil is locked in the storage. This method of feeding high-speed stranding machines is still far too time consuming and does not allow an automated loading process.

Object of the invention

The aim of the invention is to reduce the time required for to shorten the loading process and guarantee a smooth process.

Explain the essence of the invention

The invention is based on the object of developing a method for feeding high-speed stranding machines, that ensures that all necessary work steps are carried out automatically.

According to the invention, the task is solved by the following work steps »

- Shut down the machine and open the protective hood, manual implementation

- Turning the "stranding rotor" in the loading position, switching pulse electrical, due to schedule switching

- Lifting movement of a locking device arranged under the floor, Unlocking and disconnecting device, abbreviation AET-Vorriehtung

- Locking of the bobbin frame. AET preparation and Connection of the compressed air system to the reel storage, open the same

- Triggering of the disconnection process

- Lowering of the loading traverse arranged on the protective cladding of the stranding machine

- Simultaneous picking up of the empty ones in the rotor Spool and a full spool provided outside of the stranding machine by the two grippers

- Lift the loading crossbar to the upper end position - Turn the loading crossbar by 180 °

321709g

- Lower the loading traverse, insert the full bobbin in the bobbin frame, place the empty bobbin on the roller conveyor

- Block compressed air supply via ABT pre-device, coil in Lock the bobbin frame

- Traverse raised, gripper open

- AET device moved back to the lower end position

- Weld the wire ends and smooth the welds. Process manually

- Check the reel lock visually - close the protective hood, manually

- Switch on the stranding machine drive, manually

This created a method for charging Schnellverdeilraascbinen developed, through which a continuous loading process is achieved without major manual intervention and loss of time will. It does not matter whether the coils are changed individually and one after the other or all together.

Embodiment

The method is to be explained in more detail with the aid of the exemplary embodiment of a Bescbickeinrichtung shown in the drawing will. It mean »

Fig. 1 shows the pipe section of a high-speed stranding machine

Loading traverse in side view FIG. 2 is an end view of the high-speed stranding machine with loading cross member and locking-unlocking-separating device (AET)

3 shows a part of the stranding rotor in a longitudinal section AET device.

If the stranding machine is to be loaded with new bobbins, it is first shut down. This is still done manually by the operating personnel. To do this, the protective hood is opened. When the protective hood is opened, the process begins automatically Running loading process · The signaling for the individual work processes is either via a schedule circuit realized or controlled by microprocessors.

The order of the work steps is determined as follows »

The stranding rotor is rotated into the loading position, ie the loading openings are exactly perpendicular to one another. The locking, unlocking and separating device (abbreviated to AET) 2 located below the stranding rotor 1, namely under the reel frame 3, moves into the upper end position and locks the freely rotatable reel frame 3. At the same time, the compressed air connection for the reel unlocking is established. A new signal causes the compressed air line to open and the coil bearing releases the coil. At the same time, the compressed air activates wire cutters attached to the AET 2, which cut the wire coming from the spool. The next signal causes the lowering of a loading traverse 4, which is arranged on the protective covering of the high-speed stranding machine and has a gripping device at each of its two ends. One of the two gripping devices is exactly above the bobbin storage and the other above the bobbin provision.When lowering the loading traverse 4, the gripping device grips over the two bobbins, whereby the gripper arms close automatically under the spring force and the subsequent raising of the loading traverse 4 into its upper one Cause end position. If this is reached, a further signal occurs, as a result of which the loading cross member 4 rotates through 180 ° in the horizontal plane. Then the signal "lower ¹ *" occurs and the loading traverse 4 moves to the lower end position. The full bobbin is inserted into the bobbin storage and the empty bobbin is placed on the roller conveyor 5. The loading traverse 4 then moves to the upper end position with the grippers open and is turned back by 180 ° to the starting position. Then the signal "Close compressed air valve ¹¹ " comes out, which means that the coil is locked again. The wire ends of the coils are welded to the wire ends in the stranding machine. The AET device 2 then receives the "lower" signal and it moves into its lower end position. This is followed by the visual locking check and the closing of the protective hoods. The high-speed stranding machine can be started up again. All other operations, such as transporting away the empty bobbins and providing the

full bobbins, during the running tent of the high-speed stranding machine made by the operating personnel and therefore do not reduce their performance.
