The invention relates to a packaging device and a packaging method having the features in the preamble of the method and device main claim.

Such a packaging device is from the

WO 88/009748 AI known. It serves for the packaging of pressed bales on a baling press by means of a strapping and a multi-part bale wrapper which has an upper part, a lower part and a jacket-shaped side part. The controllable packaging device has a

Strapping device, a supply device for the upper part and the lower part and a transfer device for the side part. The strapping device and the transfer device are at one along the press bale during the packaging process in a feed direction

movable transport device arranged together. The feeding device is arranged separately from the side of the baler and leads the upper part and the lower part with an active feed movement from the outside into the baler and to the press ram. In another variant of this document, the upper part by the feed movement of a press box of a

Stationary winding on the way to the baler

taken and held on the box top. A pivotable winding on the transport device pivots in its return movement on the lower ram, wherein the bottom part is pulled with clamping fixation in this direction over the lower ram.

Another packaging device with a modified handling device is known from DE 40 15 642 AI. The supply of the upper and lower part of the bale wrapper will not be explained. It is an object of the present invention to provide a

show improved packaging technology. The invention solves this problem with the features in

Process and device main claim.

The claimed packaging technique, i. the

Packaging device and the packaging process and the baling press equipped therewith or

Baler, have different advantages.

With the claimed packaging technology is a

achieved significant increase in performance. It can be packed more bales per hour than with the prior art.

The increase in performance can be achieved by quickly supplying the upper part and lower part of the bale wrapping. Feeding may occur during or immediately after the delivery of the just previously packaged press bale from the baler.

This temporal relationship has the advantage that the process times for the bale delivery and for the feeding can be overlapped. This leads to a

Shortening the time required for the packaging of a

Press bales and to a corresponding

Increased performance of the packaging technology and the baling press equipped with it. The baler can immediately by the claimed packaging technology for the

be prepared for the next pressing and packaging process. The packaging device and in particular their

Feeding device can be designed and controlled accordingly. The taken by the transport device

Feeding device with the upper and lower parts, which are preferably already ready to feed, can already be approximated to the feeding position on the baling press during the attachment of the bale fixing device and can immediately after

Completion of the fixing process in the feed position and before s freely accessible bales are moved.

For this purpose, a quick and short movement of the

Transport device in said delivery direction. The transport device does not need to return to its rest position as in the prior art.

It is also beneficial that the feeding movement of the upper and lower part and the Ballenent charge in the same

Direction and can be done across the delivery direction. The feed motion may be straight and require only a short feed path.

With the claimed feeding technique, both the upper part and the lower part of the bale wrapping can be fed from the feeding device. Upper and

Lower part can be supplied time-saving simultaneously or offset in time. The upper and lower part of the bale wrapping can be spread as wrapping material in the form of lying,

leaf-like and flexurally elastic wrapping agents,

in particular Hüllmittelzuschnitten present. The

Enveloping agents may be selected from a suitable one

foil-like material, e.g. Plastic, consist. The material can be inert to the fiber material of the

Pressballens, causing contamination of the

Fiber material can be avoided. For this it is also beneficial if the bale fixation, e.g. in the form of a ballenumreifung with several metal bands, outside on the previously attached to the pressed bales bale wrapper

is applied. The wrapping means may be provided to the feeder in an in-feed orientation,

in particular in a horizontal parallel orientation of its main plane relative to the main plane of the respective associated press ram. They can be moved from this position with a short and straight feeding movement in the baler and possibly handed over to there Hüllmittelhalter. Furthermore, the packaging quality can be increased. The feeding of upper part and lower part of the bale wrapping can be done with a defined and controllable feed movement. In this case, an exact positioning of the upper and lower part in the baler is possible. Preferably, the positioning and arrangement of upper and

Lower part of the bale wrapping at the press dies. This can be done in direct contact or near the press die. With the claimed feeding technique, the upper part and the lower part before pressing a

Press bales are fed into the baler, in particular on the press die.

The bale wrapper covers and preferably encloses the pressed bale on all sides. Alternatively, one is

Partial coverage possible, e.g. at the top and bottom

Ball area. The bale wrapping can lie close to the pressed bale and be held by the bale fixation. The claimed packaging technique is suitable for a bale wrapping with the said three parts. In another embodiment, it is also suitable for a two-part bale wrapper having a top and a bottom part, wherein a preferably jacket-shaped side part may be missing. In such an embodiment, the handling device for attaching this side part on the press bale is also unnecessary. The arrangement of Handling device on the transport device is optional in this respect.

Preferably, the side part of the bale wrapper forms a closed shell or an annular shell

Abdomen around the upright side surfaces of the

Press bale. The constructive training of

Handling device may vary. The

Transhipment device inserts e.g. for the formation of the

jacket-shaped side part a wrapping means of the aforementioned type by means of a co-moving in the feed movement, spanned Hüllmittelvorhangs or by means of a sweeping looping movement around the pressed bales and closes it annularly by means of a separation and

Welder. In this case, the enveloping agent is also separated from a Hüllmittelvorrat.

be formed and can the wrapping means (37) from a single Hüllmittelvorrat (38) deduct and in a bow or looping motion around the pressed bale (6)

lay around and then with the separation and

Welding device (39) bring the wrapping material or the abdominal binder in a ring shape, close and from

Disconnect wrapping agent supply. Such

Transhipment device (24) can eg according to DE 40 15 643 AI be formed.

The handling device (24) can in another

Variation also omitted. Here, a two-part bale wrapper (7) can be formed, consisting only of upper and

Lower part (8,9) is formed, wherein these at the

upright side walls can overlap each other.

The feeding device (25) can be turned away. It may be e.g. only one feed means (26) which receives both enveloping means (28) and

height adjustable on the frame (33) is guided and which time-shifted and successively the upper and lower part (8.9) of the baler (2) supplies.

Also, the manufacturing device (29) can be modified. It can be completely executed in one execution

Feeding device (25) may be arranged, wherein e.g. on the frame (33) and the Hüllmittelvorräte (32) at the

Feeding device (25), in particular on the frame
