Description

The invention relates to a packaging device for a baler with the features in the preamble of the main claim.

A packaging device for highly compressed pressed bales on a baler is from the EP 0 294 820 B1 known. The packaging device has a supply device for a film web and a wrapping device for attaching a surrounding film jacket to the press bales held between press dies, which form a spatial and kinematic unit and are arranged together on a transport means. The packaging device tightens a film curtain and places it as a belly band around the press bale.

The EP 0 528 892 B1 shows a variant of such a packaging device with a different structural design of the supply device and the wrapping device.

The US 2007/0 220 832 A1 concerns the packaging of free and open cargo with a film web. In this case, free access to five open sides of the article to be packaged is required in order to be able to fold the film web several times. Packaging technology is unsuitable for the packaging of pressed bales between press dies.

The EP 1 029 786 A2 shows a shrink-wrap packaging unsuitable for pressed bales, whereby here too the piece goods to be packed are freely accessible on five sides.

It is an object of the present invention to show a better packaging technique.

The invention solves this problem with the features in the main claim.

The claimed packaging technology, in particular the packaging device and the packaging method, have the advantage of increased performance and improved safety.

As a result of the spatial separation, the supply device can be arranged at a distance from the pressed bale or to the baler and thus outside a safety area on the baling press. This allows a change or replenishment of packaging material, especially coils, without disturbing or stopping the baler for safety reasons.

The supply device can be arranged stationary, which facilitates the handling and the change of the packaging material, in particular coils. The stocking capacity can be significantly increased. There is enough space for spare coils. In addition, a connection of the tail of the coil change much easier and faster.

Further advantages are the space and weight savings on the means of transport, which only has to transport the wrapping device. This can also lead to improvements in the acceleration and the driving speed of the means of transport, which also has a performance-enhancing effect. Also favorable are improved accommodation options for one or more additional devices on the means of transport, eg. B. a strapping device.

The claimed packaging technology is particularly suitable for high-performance baling presses. In this case, a baler can also be subdivided into a prepress and main press area. The claimed packaging technique may also be used for attaching additional packaging means, e.g. B. a Dehnhaube be supplemented. In addition, it is possible to attach to the press bale an upper and / or lower cover sheet, which can be done during the pressing.

In the subclaims further advantageous embodiments of the invention are given.

The invention is illustrated by way of example and schematically in the drawings. In detail show:
