Description

The present invention relates to a device for drawing a winding shaft from a roll of material, comprising at least one base frame with at least one disposed on the underside of the base frame bottom support, and at least one arranged on the top of the base frame clamping device for clamping holding the winding shaft.

Winding shafts are used for winding endless web-like material made of paper, foil or fibers. The winding shaft forms the core for winding or winding web material into large transportable rolls after production. On the winding shaft, a cardboard or plastic sleeve is often pushed onto which the web material is wound directly. For clamping, the winding shaft on mechanically, hydraulically or pneumatically actuated clamping means, which increase the diameter of the winding shaft after sliding the sleeve and clamp the sleeve so tight. After winding, the winding shaft is pulled out of the cardboard or plastic sleeve. For this purpose, the winding shaft on at least one end at least one circumferential groove, which should facilitate handling, storage and transport.

Depending on the width of the web, the winding shaft may have a weight of more than 200 kg and a length of more than 5 m. In particular, by the winding process loads a high contact pressure on the winding shaft, which can be pulled out of the cardboard or plastic sleeve even with relaxed clamping means only with increased force. According to the prior art, each winding machine has its own device for removing the winding shafts, which is often rail-bound and therefore can not be used in the other winding machines. This makes the winding machine unnecessarily expensive.

The invention is therefore based on the object to provide a device for pulling winding shafts that can be produced inexpensively and flexibly for a variety of winding machines.

The solution of this object is achieved by the features of claim 1. Further advantageous embodiments are claimed by the subclaims.

The inventive device for pulling a winding shaft from a roll of material comprises at least one base frame, on the underside of which at least one bottom support is arranged, and at least one arranged on the upper side of the base frame clamping device for clamping holding the winding shaft. The invention is characterized in that the base frame has at least one receiving opening which is designed to receive at least one transport fork of an industrial truck.

The device according to the invention has the advantage that it can be used independently of a single winding machine. It is not rail-guided and can be used with any transport vehicle whose transport forks correspond to the receiving openings. Another advantage is the cost-effective production, since the device has no own drive or driving system. The combination with an existing industrial truck makes the device very flexible, inexpensive and compact.

With further advantage, the base frame on two receiving openings, which are spaced from each other. This ensures a secure form-locking guidance of the device on the transport forks of a material handling vehicle.

Preferably, the at least one clamping device has a base body and a lid, which are movably connected by means of a hinge. By the hinged opening of the lid, the clamping device is opened and can accommodate at least a shaft or a part of the winding shaft.

In this case, the base body and the lid each have a half cylinder bore, which form a cylindrical cavity when the clamping device is closed. By means of flange and releasable clamping device, the clamping device is closable and thus takes on at least one end of the winding shaft by clamping.

Characterized in that two clamping devices are arranged spaced from each other on the upper side of the base frame, whose longitudinal axes of the cylindrical cavities are aligned, the winding shaft can be clamped at two points, so that the bending of the winding shaft is reduced due to its own weight. The two spaced-apart clamping devices have the advantage of cost-effective production and weight savings compared to a one-piece long clamping device, since the clamping device - to avoid damage to the winding shaft - are made of a soft material such as copper or bronze, which is relatively expensive.

A preferred embodiment provides that at least one clamping device on the Cover has an opening with a projection. The opening is configured to receive a portion of one end of the winding shaft during the first phase of extraction.

The projection, however, is designed to engage in a groove of the winding shaft. About the positive connection of the projection in the groove of the winding shaft, the first pulling out of the winding shaft from the roll of material takes place. However, the winding shaft is not yet clamped and could fall by its own weight on the ground.

Only in the second phase of pulling out, when the winding shaft is clamped by the clamping devices, it can be completely pulled out of the roll of material. The start of the industrial truck is facilitated by a stop which is arranged in the region of an outer edge of the base frame, which is opposite to the clamping device with the opening and the projection. The stop cooperates with an end face of the winding shaft.
