Fig. 3 is a drawing similar to Figs. 1 and 2, but where the wrapped low weight round bale is about to leave the wrapping machine in accordance with the present invention.
Detailed description Construction details
Now referring to Fig. 1, a wrapping machine is shown in general by reference numeral 200. The wrapping machine 200 comprises a non-rotating wrapping table 201 having a first roller 202 and a second roller 203 (shown in two positions 203' and 203"), both arranged rotary therein, arranged to co-rotate about a substantially horizontal axis by drive means (not shown). The purpose of the first and second rollers 202 and 203 is to rotate the round bale 300 about an substantially horizontal axis, and to support the lower part of a round bale being wrapped with an elastic or flexible encapsulating material, such as a net or a plastic film, hereinafter denoted as plastic film or wrapping film.
The wrapping film is dispensed by a wrapping film supply device 205 which is arranged to dispense a continuous web of plastic film 206 from a supply roll or similar. The film supply device 205 is advantageously provided in the form of two plastic film dispenser rolls arranged on diametrically opposite sides of the wrapping table 201 and arranged to rotate in a horizontal plane around the wrapping table 201 during a wrapping operation.
The non-rotating wrapping table 201 exhibits a first end 20 arranged adjacent to a round bale compactor 100 at an outlet of the latter, and a second end 201". A compactor chamber is illustrated at reference numeral 101, where compacting means known per se performs compression forces on for example grass to produce a round bale.
Moreover, the wrapper table 201 is arranged tiltable about a pivotal means 208 between an erected substantially horizontal position (Fig. 1), elevated at a height above the ground, and a lowered position (Figs. 2 and 3) where the second wrapping table end 201" has been lowered to a position closer to the ground.
An elongate ejection tray 207 is arranged pivotal about a pivotal means 210 to the second end 201" of the wrapping table 201, exhibiting a first end 20 arranged to bear against a round bale 300 by one or more support rollers 204, and a second end 207" arranged to rest on the ground in a round bale deployment process (Figs. 2 and 3) when the wrapping table is in the lowered position.
Particularly with reference to Fig. 1, the second roller (203) is shown in a first position 203' arranged to support a smaller low weight round bale 300, and a second position 203" arranged to support a larger customary round bale (not shown). The second roller (203) can be positioned steplessly between the first position 203' and second position 203" in a guide 209 manually, or by a mechanical drive (not shown), e.g. hydraulically or electrically driven.
Round bale wrapping operation
In an operation of wrapping a plastic film around a round bale, the round bale is ejected from a compactor 100 by a round bale supply means 102, for example a mechanical impact device, onto the wrapping table 201. Then the round bale 300 is brought into rotation about its longitudinal horizontal direction via rotation of said first roller 202 and second roller 203 (indicated by two of its extreme positions 203' and 203"), supported by support roller 204. Plastic film 206 is drawn from film supply device 205, typically plastic film rolls arranged rotary on a vertically extending strut, while round bale 300 is rotating on wrapping table 201 until the round bale 300 is completely encapsulated by plastic film 206.
Round bale deployment
Fig. 2 shows a point in the wrapping process where the round bale has been wrapped by plastic film and is ready to be deployed to the ground. The wrapping table 201 has now been titled down to a lowered position where the second wrapping table end 201" has been lowered to a position closer
to the ground. The ejection tray 207 has now been pivoted with its first end 207' arranged adjacent to the wrapping table 201, and with its second end 207' resting on the ground.
After the wrapping film 206 has been cut, an ejector means (not shown) brings the wrapped round bale 300 out of its position, whereupon the round bale 300 rolls down along the ejector tray 207 and down to the ground (Fig. 3). Then, the wrapper table 201 is erected back to its wrapping position shown in Fig. 1, ready to receive another round bale to be wrapped.
Modifications
Whereas only the second roller 203 has been described as movable, the first roller 202 can alternatively also be arranged movable, or both the first 202 and second roller 203 can be arranged movable.
The compactor can advantageously be provided with a size sensor (not shown), preferably in combination with a round bale weight sensor (not shown), that terminates the compacting process in compactor chamber 101 when the round bale has achieved a desired size and/or weight.
Moreover, wrapping machine can be provided with a controller and round bale sensors that automates the position of the first and second rollers 202 and 203, preferably combined with size and/or weight sensors in compactor chamber 101 described immediately above.
Technical effect
The adjustability of the first 202 and/or second roller 203 provides a sturdy engagement with a round bale being wrapped by plastic, thus preventing a smaller low weight round bale to be squeezed out of position between the rollers 202 and 203. As a result, a wrapping process can proceed uninterrupted.
Moreover, thanks to the optional controller and sensors describes in the section Modifications above, the wrapping machine can operate more efficiently than before and can more or less automatically switch between varying round bale sizes and round bale weights and provide an optimal positioning of the first 202 and/or second roller 203, and provide an optimized wrapping process.
