Description

Wire winding machine and method of operating the same

The invention relates to a wire winding machine, comprising a receptacle with a substantially vertical coil axis, on which a wire spool is rotatably fastened, and an operating device to perform a bobbin change.

Furthermore, the invention relates to a method for operating a wire winding machine, wherein a wire spool in a receptacle with a substantially vertical

Coil axis is rotatably mounted and a wire is at least partially manually manipulated in a bobbin change.

Such wire winding machines and methods have already become known from the prior art. So trained as unwinders or as a rewinder

Wire winding machines are known in which a wire coil weighing several tons is wound off or wound up via a roller bearing. Unwinding machines

used, for example, in production facilities where large quantities of wire are processed into products. Wire spools are transported to the mostly multiple parallel machines and wound in the unwinding of the wire from the coils. Via wire guiding devices, the wire is subsequently transported to a production machine, in which the wire is processed into a product, for example a cable. Similarly, rewinders are used, for example, in production facilities in which wire is made to automate the wire on the

To wind wire spools. Because the wire is continuously needed or produced, rapid replacement of the wire spools is important for an efficient production process. In order to ensure a continuous process, when a bobbin change wire of the coil must be connected to a wire of the production process. At a

Unwinder, a wire end of the wire spool is connected to a wire in the production process; in a rewinder, a produced wire is attached to the bobbin after the bobbin change. In any case, a manual change is required when changing bobbins. Because the coils, as stated above, are sometimes several tons in weight, the bobbin change involves a high risk of injury from poorly secured and falling wire spools. This risk of injury is currently covered by safety precautions, which is why the

Wire wrapping machines are structurally complex and expensive. This also has disadvantages for the method, since a large amount of time is required for a bobbin change, whereby an efficiency is low.

The object of the invention is therefore to provide a wire winding machine of the type mentioned, which is simple and at the same time minimizes the risk of injury.

In addition, a method of the type mentioned above is to be given, which has improved efficiency over prior art methods.

The first object is achieved in that at a

Wire winding machine of the type mentioned in the recording in a plan view is spatially separated from the operating device.

In this way, the risk of injury is avoided, as an operator at a

Bobbin change does not come into contact with the wire spool. At the same time can on

Safety precautions for the bobbin change are waived, so that the

Wire wrapping machine is easier and cheaper to produce.

It is favorable if the coil axis is arranged on a pedestal and the

Operating device is positioned on one side of the base. Preferably, a drive of the coil axis is arranged in the base, so that a space requirement is minimized. It can preferably be provided that the operating device covers 30% to 80%, in particular 40% to 60%, of the side of the base. So there is enough room for an operator to handle manually when a bobbin change.

In addition, several wire winding machines can be arranged directly next to each other, whereby a space-saving system is formed.

In order to make optimum use of available space, it is expedient if the receptacle and the operating device in a plan view on opposite sides of the

Wire wrapping machine are arranged. In this way, an arrangement of Wire wrapping machines in rows are particularly easy. At the same time, a risk of injury due to the spatial separation is further reduced.

Preferably, a wire tensioning device, in particular a dancer, is provided.

So-called dancers have proven themselves to ensure a continuous wire tension. These are usually discs around which the wire runs and which exert a bias on the wire. The bias can be done for example via a weight or spring load of the disc. Conveniently, a buffer memory is provided so that when a bobbin change a continuous operation is possible. It is particularly advantageous if such a buffer memory, which often comprises a wire spool, is arranged in the region of the operating device in order to minimize a base area of the wire winding machine. Also, maintenance of the buffer memory, which is preferably positioned behind a wire mesh cover, is then easily possible for the operator. Conveniently, the

Buffer memory arranged on the side of the base, on which the operating device is positioned. In a top view, the wire winding machine then preferably consists only of the base and the operating device on one side of the base. If the wire is cached in the buffer memory, there is a continuity of the

Production process also given during the bobbin change. At a

Rewinder becomes wire made during bobbin change in the

Buffer memory stored; in an unwinder wire is removed from the buffer memory during the bobbin change. The buffer memory may, for example, comprise a coil via which the wire is guided from the wire spool into the production facility.

Advantageously, an electrically driven pulley is provided with which wire from the wire coil can be unwound. This allows a well regulated

Extraction speed with high reliability.

In order to enable a particularly efficient method, it is favorable if a wire can be connected to the operating device. Thus, the operator can do the necessary with a bobbin change activities with little movement. High amounts of wire can be processed if a plurality of wire winding machines are arranged in a wire winding machine, with wire coils are transported with a preferably driverless conveyor vehicle from or to the wire winding machines. It is advantageous if a wire winding machine with wire winding machines and a particular driverless conveyor vehicle at least two inventive

Wire wrapping machines includes. Because the wire winding machines according to the invention because of the separate arrangement of operating side and recording have a particularly small footprint and are easy to load and unload, a wire winding system can be implemented so particularly space-saving and efficient with particular driverless transport vehicles.

It is advantageous if the wire winding machines are arranged in at least one row and loading and unloading of the wire winding machines can be done by means of at least one conveyor vehicle from a first gear, while an operation of the wire winding machines can be done from a second gear, and the two Gears are spatially separated. So are logistics possibilities of

Optimum use of the wire winding machine according to the invention, whereby a need for base of the wire winding machine is minimized. Conveniently, the first gear and the second gear are approximately parallel and separated by the wire winding machines. This minimizes operator risk of injury due to driverless or dropping wire coils. Furthermore, for a service of a wire winding machine, a flow of material from wire spools transported from or to wire winding machines need not be interrupted because operators and conveyor vehicles operate in different courses of the wire winding installation.

Advantageously, at least four wire wrapping machines are arranged in at least two rows and the operating sides of wire wrapping machines each directed two rows to each other. Thus, large amounts of wire can be processed very efficiently, because each two rows of wire wrapping machines can be serviced by an operator gear between the rows. At the same time, bobbin change can be done on many machines with minimal manpower, as paths that an operator has to travel are minimized. The further object is achieved in that is manipulated in a method of the type mentioned, the wire on a in a plan view spatially separated from the recording control device. On the one hand, such a risk of injury due to a rotating wire coil is minimized. On the other hand, in this way, loading and unloading can be performed simultaneously with an operation of the operator, so that an efficiency of the method is increased.

Preferably, the wire is connected and / or welded. Depending on whether the

Wire wrapping machine is used as a winding or unwinding, it is necessary

To connect wire ends or to attach a wire end to an empty wire spool. Due to the separate arrangement of operating side and recording these activities can be done simultaneously with a bobbin change.

It is favorable if the wire is manipulated, while the wire coil on the

Wire wrapping machine is changed. This minimizes the time needed to change bobbins.

It can be further increased the efficiency of the process when the wire coil is automatically changed by means of a particular driverless carrier vehicle. It is particularly advantageous if the wire winding machines are connected via a control system with several conveyor vehicles and a bobbin change is initiated automatically. Manual activities are then preferably limited to connecting wire ends or connecting a wire end to an empty coil. Because the manual activities take place from the operating side which is spatially separated from the recording in a plan view, the operator is not endangered or restricted by automatically moving conveyor vehicles.

Transport paths are minimized and a space requirement of the system is optimized when several wire wrapping machines are loaded and unloaded by at least one movable between the rows in particular driverless transport vehicle. Particularly preferably, the wire winding plant consists of several rows of wire winding machines, wherein alternately a transition between the wire winding machines exclusively from

Handling vehicles and a gear exclusively for operators of the Wire wrapping machines is provided. This ensures an optimal process with minimum risk of injury.

Further advantages, features and effects of the invention will become apparent from the embodiment illustrated below. In the drawings, to which reference is made, show:

1 shows a wire winding machine according to the invention in an isometric view;

FIG. 2 a top view of a wire winding machine according to the invention; FIG.

3 shows a section of a layout of a wire winding installation;

4 shows a schematic layout of a wire winding installation.

Fig. 1 shows a wire winding machine 1 according to the invention in an isometric view. In addition to the wire winding machine 1, an operator is shown schematically, who handles an operating device 5 of the wire winding machine 1. Further, behind a grid, a buffer memory 6 can be seen, in which wire is stored to at a

Bobbin change to ensure continuous operation. It is apparent that a receptacle 3, via which a wire coil 2 can be fastened on a vertical coil axis 4, is provided on a base 7. The receptacle 3, via which the wire spool 2 is transferred to the wire winding machine 1, is accessible from one side of the wire winding machine 1, which faces the operating device 5 in a plan view. As shown, the wire winding machine 1 is constructed such that the vertical coil axis 4 is arranged on the base 7 and the side of the base 7, the operating device 5 and the buffer memory 6 are provided on the base 7. In this case, a lateral space requirement of the operating device 5 together with the buffer memory 6 is preferably 30% to 80% of the side edge of the base 7. In this way, the wire winding machines 1 can be arranged at an accessibility for the operator directly next to each other. Fig. 2 shows a wire winding machine 1 according to the invention in plan view. It is particularly apparent that the base 7 protrudes laterally only slightly beyond the dimension of a wire coil 2, to be able to take advantage of space requirements in a production facility particularly well. Shown further is that the operating device 5 in the

Top view opposite the receptacle 3 is arranged. FIG. 3 shows a section of the layout of a wire winding installation 8. As shown, the wire winding machines 1 are arranged directly next to each other, wherein the

3 shots of a series of wire winding machines 1 are oriented in a direction in which a vehicle gear 10 is located. In vehicle gear 10, a driverless conveyor vehicle 9 is shown schematically, with which a bobbin change is carried out automatically. There are two rows of wire winding machines 1 as shown aligned such that the receptacles 3 of the two rows have a vehicle gear 10. In this way, wire winding machines 1 two rows of a arranged between the rows of vehicle gear 10 and one in the

Vehicle gear 10 traveling conveyor vehicle 9 are loaded or unloaded. Operators move as shown in spatially separated from the conveyor

Operator gears 11. Because all operating devices 5 of the wire winding machines 1 in operator gears 1 1 have, so can an operator of an operator gear 1 1 the

Wire wrapping machine 1 of two rows wait and manual activities of a

Change the bobbin. When a bobbin change a wire spool 2 is preferably fully automatically transported by a conveyor vehicle 9 on the wire winding machine 1 and fixed there automatically. Simultaneously with the attachment of the wire spool 2, the operator performs the necessary manual operations. These are

For example, the joining or welding of wire ends, if the

Wire winding machine 1 is operated as an unwinder. When the wire winding machine 1 is operated as a winder, an operation of the operator includes attaching the wire to the wire bobbin 2.

Fig. 4 shows schematically a layout of a wire winding machine 8. It can be seen that all wire winding machines 1 are arranged such that the

Wire winding machines 1 are positioned in a plurality of rows, wherein the receptacles 3 of wire winding machines 1 two rows are each directed to each other, so that the wire winding machines 1 two rows can be loaded or unloaded by a arranged between the rows of vehicles 10 gear. It can also be seen that the operating devices 5 of wire winding machines 1 of two rows are also directed toward one another, which is why the wire winding machines 1 of two courses are accessible to operators from an operator gangway 1 1 arranged between the gangways. Due to the separation of the operating device 5 and the receptacle 3, via which the wire spool 2 is mounted on the wire winding machine 1, the operator is always spatially from a material handling system, which can be moved by means of driverless

Conveyor vehicles 9 performs the bobbin change, separated. The operator can thus prepare for a bobbin change a welding of the wire or connecting the wire to the wire spool 2, while the wire spool 2 is automatically changed by the material handling system. This allows the bobbin change with much less

Personnel deployment and be carried out with a considerable time savings compared to devices and methods of the prior art. Because the working areas of the operators and the conveyor vehicles 9 are spatially separate, there are no special requirements

Safety arrangements for a bobbin change, whereby the wire winding system 8 is carried out particularly low. Furthermore, due to the compact layout, a particularly good use of a production site area becomes possible.
