Description

The invention relates to a device for storing and transporting a wire coil and for unwinding of wire from the same wire coil.

Wires, especially welding wires, are frequently after their manufacture to wire coils of several hundred kilograms Weight rolled up and stored in this form by the wire manufacturer and finally delivered. In this context, it has proven itself to Storage and transport of the wire coils using our own facilities in which the wire coils are inserted. The wire coils are then against environmental influences, for example precipitation, better protected and corrosion of the rolled wire can be kept behind. Furthermore is a Wire winding, which is in a facility like a closed container is largely against mechanical during storage and transport damage protected.

When storing and transporting Wire wrapping is generally used in polygonal containers because of this container can be arranged to save space than round containers and at most even a complete one Allow container arrangement.

If containers are polygonal, so they usually have flat side walls. When transporting can the containers are therefore laid against one another with the respective side surfaces, which also causes a madness or slipping of containers is difficult. An angular shape of containers is therefore also regarding a safe transport.

Devices with polygonal receptacles of wire coils are said to be inexpensive be producible and best possible consist of individual parts that are reusable or otherwise one Be recycled can. The containers should be made of a material that has a wire winding upon contact with the container not mechanically damaged. This is particularly important for copper-plated welding wires: a partial scratching or abrasion of material from the surface as a result that when creating a weld seam is not continuous Filler metal of the same chemical composition is supplied. In such a case, the amount of filler material supplied per time also varies, which is therefore not constant. Due to such discontinuities in the feed of welding wire it can happen that the theoretically achievable quality of a Weld is not feasible in practice.

When processing a wire it may be desirable be to leave it in the facility that is already for transportation and bearings was used and withdrawn from it or ablate. This is especially true in the area of welding wires. For example, welding wire wrapping is used in the automotive industry delivered in appropriate facilities and the welding wire out these facilities directly out of so-called welding robots fed.

The aim is to unwind the wire of the wire winding, which is kept in stock in a container, in particular when welding for the reasons mentioned above preferably without mechanical damage of the wire. Confusion or loop formation is also intended of the wire can be prevented. These adverse effects can occur because a coiled wire tries to unroll itself again and to form loops and / or climb up the side walls of a container.

To climb a wire on side walls a container to prevent it has already been proposed to provide holding means. Such holding means are inserted into a container after a wire winding and are designed so that the wire rises on the side walls during a Storage and transport as well as during the removal or removal is prevented by blocking the high-rise routes for the wire. Such holding means have openings through which the wire is passed for removal can.

It is now recognized that, on the one hand a holding means or its opening area should be designed to be robust because only then can it be pulled off evenly of wire without material failure of the holding means and without formation of wire loops or confusion of the wire is possible, that on the other hand this despite the robustness of the holding means in the event of contact with the wire, no mechanical damage to the May cause wire.

The above requirements are in the storage facilities known from the prior art and transporting a wire wrap and for pulling wire of the same wire winding, which metallic or cardboard holding means include, insufficient considered.

This is where the ending comes in and provides the task of specifying a facility of the type mentioned at the beginning, which prevents the wire from climbing up on the side walls and from which a wire from a wire coil is essentially without mechanical damage as well as evenly removable is.

The task at hand solves one Device according to claim 1. Advantageous further developments of the invention are the subject of the claims 2 to 17.

The advantages achieved with the invention are to be seen in particular in the fact that in a generic device by means of a holding means, which is made of plastic at least in the area of the passage opening for the wire, a wire even without contact with the holding means Damage can be carried out continuously. In particular, damage can be avoided even with copper-plated wires; this can be explained with favorable friction coefficients of copper compared to plastics or a favorable material pairing. Compared to cardboard holding devices, holding devices which are made of plastic at least in the area of the through opening are considerably more durable; tearing of the holding means, as in the case of cardboard, is practically not observable, and therefore a wire can be pulled off through the through opening evenly and without tangling on the holding means. At the same time, rising of the wire on the side walls of the container is prevented.

If the holding means is a plastic plate, their outer contour that formed by the side walls Minor polygon corresponds to smaller dimensions, so that the plastic plate in the container can be inserted, it is not only effective to climb the wire prevented, but it is also the overall holding means simple and inexpensive to manufacture. The holding means can also hold the wire over the entire cross section of the wire winding without holding the wire down due to the Contact with a holding device is damaged.

A particularly gentle execution of a Wire through the holding means with at least temporary contact with the same it is possible if that's the through hole for the wire forming areas of the holding means at least on one side thereof rounded, preferably smooth and rounded, are formed.

It has proven itself in use, if the holding means is made of polypropylene or polyethylene. The Holding means is then not only inexpensive to manufacture, but also also has a long shelf life and can therefore be used many times be used. Conveniently, the holding means is created in one work step by injection molding.

Since wire coils are usually round are and wire is drawn along a circle, it is convenient if also a through opening for the wire circular is trained. The wire can then be pulled out in the same way as for the pulling direction glide in a circle at the edge of the feed-through opening.

The container itself is preferably from cardboard. container of such material have sufficient stability and can be used several times. If they are no longer usable, can they residue-free recycled become.

Basically, a device according to the invention with side walls be formed, which form any polygon in cross section. It is preferred in view of a high rigidity of the container and thus high stability the same with mechanical load, if the side walls of the container form an octagon in cross section. In particular, containers are are made of cardboard, then less prone to bumps and the side walls buckle much less easily than round containers.

To make a device according to the invention simple to be able to transport this further comprises at least one carrying means connected to the container. It is particularly useful it when a carrying means has at least two handles for one lifting means having. In this case, the device loaded with a wire winding can within a manufacturing facility with the respectively available Lifting and transport equipment, such as a forklift, is easy to be spent.

Has proven to be particularly advantageous proven due to the high weights of wire coils of 250 kg and more, if a device according to the invention comprises a support means from a band or belt. advantageously, extends the band or belt from an area of a first side wall to Bottom and along the bottom to an area of a second, diametrically opposite side wall back and forth to the container opening. In this way, when lifting the device, the heavy wire wrap not only from the floor of the facility, but also from the belt or belt carried. Even if the bottom is made of cardboard, the Furniture to be lifted or carried.

To ensure a long period of use Setup even when the container is made exclusively from Cardboard to allow extends the band or the belt on one side wall alternately on the inside and outside. With such a braiding of the band or belt in a side wall can tear out the belt or the belt can be avoided.

To be a holding device during transport and a wire wrap immovable To hold in position, it can be provided that a device according to the invention a tensioning device or clamping device for fixing the holding means covered on the wire winding.

conveniently, comprises a device according to the invention one which can be placed on the container Cover, which protects a wire coil against environmental influences during a Storage or transport is further improved.

In one variant, there is the lid with a flat top surface educated; this proves to be advantageous in terms of space-saving stacking facilities according to the invention.

So that a wire wrap even during use or during unwinding, for example for the purpose of welding, is protected against environmental influences, the lid can have a central removal opening for the wire.

The ending is based on of figures explained further by way of example.

1 shows an example of an embodiment of a device according to the invention. A container 1 is by eight side walls of equal area and parallel to an axis A. 11 as well as a floor 12 educated. First ends 111 of the side walls 11 are with the floor 12 connected. Second ends 112 define a container opening 13 which as well as the floor 12 has the shape of an octagon.

The sidewalls 11 as well as the floor 12 can be made individually from cardboard and in the area of a first end 111 of the side walls 11 be connected to each other, for example by clips. In terms of production technology, however, it is very favorable if the side walls 11 are immediately made with tabs, which after folding and clipping together a floor 12 can form.

The container 1 offers space for a welding wire winding 2 , from the wire 21 removed and can be fed to a welding robot, for example. A holding device 3 which after the welding wire winding 2 in the container 1 is introduced, has an outer contour 31 with eight corners. The holding device 3 , which can consist of plastics such as polypropylene, is dimensionally designed so that the plate-shaped holding means 3 in the container 1 can be introduced, a rise of the wire on the side walls 11 however prevented.

When pulling wire 21 serves the holding means 3 also by the weight of the holding means 3 a gravity on the wire winding 2 to exercise which is the wire to be pulled off 21 also in the peripheral areas 321 the through opening 32 depresses and thus prevents automatic unrolling and the formation of loops. On the other hand, however, the weight of the holding means 3 be dimensioned so that the wire unwinds 21 is not particularly difficult or disabled. With regard to both of the above aspects, a plastic plate with a weight of 500 g to 900 g has proven to be optimal.

In particular during transport, it is advisable to apply a greater force to the wire winding 2 and also on the holding means 3 to hold both in a desired position. For this is a tensioning device 6 provided which consists of a rod 61 , a clamping device 62 and one with the floor 12 connected hook 63 consists. The clamping device 62 can be a conventional rubber ring. Before a transport, this is in the hook 63 hooked in and thereby the rod 61 against the holding means 3 and this in turn against the wire winding 2 pressed. After transport, the rubber ring is removed from the hook 63 unmounted.

How further out 1 there is a single band-shaped suspension element 5 with two handles 51 . 51 ' on two diametrically opposite side surfaces 11 of the container 1 , The suspension element 5 runs from a first grip 51 proceeding to a side wall 11 , passes through it and continues inside the container 1 on a side wall 11 along before it's halfway up the container 1 emerges and outside on a side wall 11 to the ground 12 and along this to an opposite side wall 11 continues, with this mirror image of the first side wall 11 along to a second handle 51 ' runs.

The handles 51 . 51 ' serve primarily to quickly transport the device with a wire winder 2 over longer distances. It is only necessary to set up the handles 51 . 51 ' to connect with a means of transport, for example, as in 1 shown with the handle holders 71 . 71 ' a lifting device 7 ,

The device also has a lid 4 with a flat surface 41 and a centrally located removal opening 42 through which a wire 21 can be fed to a welding robot. In the area of the removal opening 42 can the lid 4 Containers are also made of plastic.

2 shows the polygonal holding means 3 out 1 in the floor plan. An octagonal outer contour 31 corresponds to a polygon as it follows 1 in the Cross section of side walls 11 is formed. Through the holding means 3 is a wire winder 2 completely covered and a climb of wire 21 on side walls 11 prevented. Through a circular opening 32 is wire 21 removable or removable.

Out 3 it can be seen that the holding means 3 in a through opening 32 defining edge area 321 is rounded. The rounding runs from a bottom 34 to a top 33 of the holding means 3 and towards the center, making a wire 21 when unwinding at the edge area 321 can slide along without coming into contact with sharp edges.

A device according to the invention, as described above, can often be used. After consumption or removal of the wire coil 21 becomes the plastic plate and the jig 6 to the bottom of the container 1 placed, this with the lid 4 sealed and returned to the supplier or wire manufacturer.
