Description

The present invention is related to a round bale wrapper according to the preamble of patent claim 1.

Background

The present invention is related to a bale wrapper for use in connection with a baler or compactor, such as described in WO 2017/023177, or other balers or compactors for production of compressed grass, straw, hay and similar.

The bale wrapper is connected to the outlet of a compactor, arranged to receive a round bale. During wrapping of plastic film or or a net of resilient packaging material, the bale is resting upon two adjacent rollers. The rollers serve to rotate the round bale while the packaging material is wrapped around the round bale from one or two positions.

The round bales produced today are normally within the weight range of 500 to 1000 kg and having a diameter of 85 cm to 120 cm. However, when producing smaller round bales, for example with a weight within the range of 50 to 100 kg, and a diameter down to 50 cm, the round bale may be twisted out of its resting position upon the rollers and fall out of the wrapper. This is particularly a problem with light weight material being wrapped, such as straw, hay etc.

JP 5373664 B describes an apparatus for wrapping a film around a round bale located upon a rotary support table. The apparatus further exhibits an endless belt connected to drive means, arranged to wrap an encapsulating film in cooperation with the rotary support table. The endless belt can be stretched and loosened to adapt to varying sizes of round bales to be wrapped.

WO 94/06292 describes a bale wrapping apparatus with a bale support table pivotally connected to a chassis. The chassis can be tipped to discharge a wrapped bale. A number of endless belts connected to drive means are provided to bring the bale to rotate during a wrapping operation. A stationary post is arranged to carry a film roll.

Object

The object of the present invention is to enable undisturbed plastic wrapping of low weight round bales in a wrapping machine.

The invention

The object above is achieved by an improved wrapping machine for round bales in accordance with claim 1. Additional beneficial features appear from the accompanying dependent claims.

The invention is related to a round bale wrapper comprising a wrapper table, arranged to encapsulate a round bale in a flexible encapsulating material, such as a flexible plastic film. The wrapper table comprises a first roller and a second roller exhibiting a gap there between, arranged rotary therein about a substantially horizontally extending axis and arranged to support a round bale. A round bale supply means is arranged upstream of the round bale wrapper to supply a round bale to be wrapped by the flexible encapsulating material. Means is arranged to bring the round bale into rotation during a wrapping procedure. The round bale wrapper further comprises a supply device for the flexible encapsulating material.

At least one of the first and second rollers are arranged movable in a substantially horizontal direction, and wherein the rollers are connected to drive means arranged to make the rollers to corotate and hence rotate a supported round bale during a wrapping operation. The wrapper table is further non-rotary but is arranged pivotal about a horizontal axis by a pivotal means and exhibiting a first end, arranged at an downstream end of a round bale supply means, and an opposite second end, wherein an elongate round bale ejection tray is arranged pivotal about a pivotal means to the second end of the wrapping table, exhibiting a first end arranged to bear against a round bale by one or more additional support rollers, and a second end arranged to rest on the ground in a round bale deployment process when the wrapping table is in a lowered position, wherein at least one of said rollers are adjustable in a substantially horizontal direction in the wrapper table to adjust a gap there between to adapt support for round bale with varying dimensions.

In a preferred embodiment, only the second roller is arranged to be positioned steplessly between a first position for small-sized round bales, and a second position for large-sized round bales.

In a further preferred embodiment, a compactor device is provided, exhibiting a compactor chamber and being arranged upstream of the round bale wrapper to supply round bales to be wrapped by the flexible encapsulating material. The compactor device can be provided with a round bale sensor connected to a controller, arranged to terminate the compacting process when the round bale has achieved a desired size.

In connection with the control arranged described above, the compactor device can further comprise a round bale weight sensor connected to said controller, that terminates the compacting process in compactor chamber when the round bale has achieved a desired weight in combination with a sensed size.

The controller described above can further be connected to a positioning device for said rollers, arranged to automate the position of the first and/or second rollers.

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 201’ 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 201’ 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.
