EMERGENCY STOP DEVICE, BALE WRAPPING DEVICE AND
HARVESTING APPLIANCE
Description The present invention relates to an emergency stop device for a bale wrapping device, having at least one actuating arm which is intended to be assignable to at least one wrapping arm of the bale wrapping device in a manner running ahead and which, upon contact with an obstacle, can activate and/or deactivate at least one function of the bale wrapping device, in particular a drive of the wrapping arm, to a bale wrapping device for enveloping a preferably round cylindrical bale with an enveloping material, having a frame and at least one wrapping arm attached to the frame in a pivotable manner, the wrapping arm preferably being able to run at least regionally around a bale to be wrapped, and to a harvesting appliance having a bale wrapping device.
Known emergency stop devices for bale wrapping devices have what are known as actuating arms, which usually run ahead of wrapping arms of the bale wrapping devices in such a way that they interrupt a drive of the wrapping arms or stop the wrapping arms when at least one of the actuating arms running ahead meets an obstacle. The obstacle can be a person or an animal who/which is intended to be protected from possible injury by the wrapping arms being stopped as promptly as possible. If the actuating arm meets an object, stopping of the wrapping arms can prevent damage to the wrapping arms, or to the bale wrapping device. Such emergency stop devices, or bale wrapping devices, can be employed on harvesting appliances, which are frequently balers which are used both in the agricultural and in the industrial sector. Corresponding agricultural balers serve for example to form bales of harvested material, for example of the round bale type, and frequently produce at least substantially round cylindrical bales of harvested material, for example of the straw, hay, chopped material, etc. type. After a bale has been formed, it is enveloped in a film or net material, to which end use is made of what is known as a bale wrapping device, which can be attached to the harvesting appliance or form an integral, fixed or detachable constituent of the harvesting appliance, of a baler or of a baling/wrapping combination, in particular of the type known as a combination baler.
Known emergency stop devices for wrapping devices are adapted to the path of the enveloping means and are preferably arranged such that they do not impede the wrapping operation as far as possible and allow the enveloping material to be severed in an unimpeded manner at the end of the wrapping operation. In particular at greater wrapping speeds, in order to ensure that the wrapping arms are stopped in good time, it may be necessary to position the actuating arm such that it impedes severing of the enveloping material and/or ejection of the enveloped bale and optionally makes it necessary to reposition the bale wrapping device or a harvesting appliance bearing the bale wrapping device.
The problem underlying the invention is considered that of specifying an emergency stop device, a bale wrapping device and/or a harvesting appliance of the type mentioned at the beginning, by way of which the abovementioned disadvantages are overcome.
The problem is solved according to the invention by the teaching of claims 1, 8 and 9, respectively. Further advantageous configurations and developments of the invention can be gathered from the dependent claims.
An emergency stop device for a bale wrapping device has at least one actuating arm which is intended to be assignable to at least one wrapping arm of the bale wrapping device in a manner running ahead. Upon contact of the actuating arm with an obstacle, the emergency stop device can activate and/or deactivate at least one function of the bale wrapping device, in particular a drive of the wrapping arm. If the position of the actuating arm is configured to be variable, or is settable in a variable manner, with respect to the wrapping arm, this position and thus the situation in which the at least one function is able to be activated/deactivated by means of the actuating arm can be adapted to the particular requirements or conditions.
It is particularly advantageous when the position of the actuating arm is settable depending on a variable predetermined by the bale wrapping device, for example a speed of movement or speed of rotation of the wrapping arms. In this way, the activation and/or deactivation can be settable in particular depending for example on the speed of movement or speed of rotation of the wrapping arms. It is in particular advantageous when the position

The problem underlying the invention is considered that of specifying an emergency stop device, a bale wrapping device and/or a harvesting appliance of the type mentioned at the beginning, by way of which the abovementioned disadvantages are overcome.
The problem is solved according to the invention by the teaching of claims 1, 8 and 9, respectively. Further advantageous configurations and developments of the invention can be gathered from the dependent claims.
An emergency stop device for a bale wrapping device has at least one actuating arm which is intended to be assignable to at least one wrapping arm of the bale wrapping device in a manner running ahead. Upon contact of the actuating arm with an obstacle, the emergency stop device can activate and/or deactivate at least one function of the bale wrapping device, in particular a drive of the wrapping arm. If the position of the actuating arm is configured to be variable, or is settable in a variable manner, with respect to the wrapping arm, this position and thus the situation in which the at least one function is able to be activated/deactivated by means of the actuating arm can be adapted to the particular requirements or conditions.
It is particularly advantageous when the position of the actuating arm is settable depending on a variable predetermined by the bale wrapping device, for example a speed of movement or speed of rotation of the wrapping arms. In this way, the activation and/or deactivation can be settable in particular depending for example on the speed of movement or speed of rotation of the wrapping arms. It is in particular advantageous when the position
- 2 -- ¨ , is selectable such that the actuating arm runs ahead of the wrapping arm to a greater extent at a higher speed of movement or rotation of the wrapping arm than at a lower speed. However, provision can also be made for the position to be able to be determined independently thereof or additionally depending on whether the bale wrapping device is in operation and/or is moving with respect to the ground, and the wrapping arms are in rotation.
Provision can be made for the position of the actuating arm with respect to the wrapping arm to be intended to be settable manually, in particular by an operator, for example before work starts. However, the position can also be changed or adjusted by an operator in the event of changing requirements and/or during operation/the wrapping process.
The position can also be intended to be automatically changeable, in particular settable and/or adjustable, however.
The position can be determined purely manually, for example by releasing a fastener of the actuating arm, for example by releasing a screwed connection, changing the position and refastening the actuating arm, for example by tightening a screwed connection.
However, if the position is determined by a control device, in particular an operator can have a direct or indirect influence by actuating for example a corresponding setting means provided in a cabin of a towing vehicle or of a self-propelled harvesting machine or on the harvesting machine or wrapping device. The setting means can act electrically, hydraulically, pneumatically or mechanically, for example via a push-pull cable. The control device can also be actuated automatically, however, for example by an electronic control and/or regulating device, for example including by an electronic control and/or regulating device of a harvesting machine or of a towing machine. However, a configuration is also conceivable in which the position of the actuating arm is configured to be determinable purely by the effect of centrifugal force or in combination with a control device.
Positioning can take place via an actuator which is able to be actively connected to the actuating arm directly or indirectly at one end. The actuator can be moved for example hydraulically, pneumatically, electrically or purely mechanically or manually and be configured in the form of a hydraulic cylinder, a pneumatic cylinder, an electric motor, for example a servomotor, a spindle drive, a push-pull cable or in any other suitable manner.

If
- 3 , the actuator is able to be connected directly or indirectly to the wrapping arm at the other end, the position of the actuating arm can be determined depending on a position of the wrapping arm.
The position can be defined by a spacing and/or an angle between the actuating arm and the wrapping arm, in particular depending on the type of attachment of the actuating arm.
The actuating arm can be provided on the wrapping device or harvesting machine independently of the wrapping arm. However, if it is attachable to the wrapping arm, it can be moved together therewith. Preferably, the actuating arm is attached or able to be attached to the wrapping arm in a pivotable manner. However, it is also conceivable to attach the actuating arm to the wrapping arm in a displaceable or other suitable manner.
A described emergency stop device can be used on a bale wrapping device for enveloping a preferably round cylindrical bale with an enveloping material, having a frame and at least one wrapping arm attached to the frame in a pivotable or rotatable manner, the wrapping arm being able to run at least regionally around a bale to be wrapped. Such a bale wrapping device can also have two or more emergency stop devices and/or an emergency stop device can have one or more actuating arms. A bale wrapping device can have one, two or more wrapping arms, which can move and/or be moved or driven independently of one another, in a manner dependent on one another and/or together with one another or jointly. Provision can be made for each wrapping arm to be assigned an actuating arm.
However, it is also possible for an actuating arm assigned to several wrapping arms to be provided. It is also conceivable for at least one one-part wrapping arm to be provided with two or more end regions that bear enveloping material, wherein again one, two or more actuating arms can be assigned to said wrapping arm. A bale wrapping device can be provided on a harvesting appliance, be attached to such a harvesting appliance connected thereto or arranged downstream thereof, for example also be pulled by a harvesting appliance or some other towing vehicle. A bale wrapping device can also be configured in a self-propelled manner, however.

A described bale wrapping device can be provided on a harvesting appliance.
Such harvesting appliances are frequently balers which are used both in the agricultural and the

Corresponding agricultural balers serve for example to form bales of harvested material, for example of the round bale type, and frequently produce at least substantially round cylindrical bales of harvested material, for example of the straw, hay, chopped material, etc. type. After a bale has been formed, it is enveloped in a film or net material, to which end use is made of what is known as a bale wrapping device, which can be attached to the harvesting appliance or form an integral, fixed or detachable constituent of the harvesting appliance, of a baler or of a baling/wrapping combination, in particular of the type known as a combination baler. Use is also possible on a baler for producing cuboidal bales or bales of some other shape.
The invention and further advantages and advantageous developments of the invention and configurations of the invention are explained and described in more detail in the following text with reference to the drawing, which shows an exemplary embodiment of the invention and in which:

Figure 1 shows a harvesting appliance 10 in the form of a baler configured as a round baler having a downstream bale wrapping device 12. In the exemplary embodiment shown, the harvesting appliance 10 has a frame 14, a chassis 16, a baling chamber 18 and a feeding apparatus 20. Also provided is a drawbar 22 by means of which the harvesting appliance
- 5 is able to be hooked up to a towing vehicle (not shown) for example an agricultural working machine or tractor. The harvesting appliance 10 can in principle be of any conventional structural type. According to the figures, the harvesting appliance 10 is a round baler. Such an appliance can have for example a fixed or variable baling chamber and be used both in agriculture and in the industrial sector. Preferably, the baler 10 is of the structural type according to German patent application 101 53 540.6, the disclosure of which is incorporated herein.
The frame 14 is formed by a welded and/or screwed assembly and is supported on the ground by means of the chassis 16. The chassis 16 is illustrated in the drawing in a tandem axle design with two axles 24, each of which is provided on each side with a wheel 26. A
configuration with only one axle or with support by means of crawlers or other suitable means is also conceivable.
The bale wrapping device 12 has a frame 30, a wrapping table or receiving apparatus 32 for receiving the bale 34 to be enveloped, and wrapping arms 36 which can be set in motion about an axis A by means of a suitable drive (not shown) in order to envelop the bale 34 with an enveloping material 38, for example a film, and an emergency stop device 40.
The emergency stop device 40 has actuating arms 42 which are each assigned to the wrapping arms 36. Lower end regions 44 of the actuating arms 42 extend substantially parallel to the actuating arms 42. In figure 2, to which reference is likewise made here, a wrapping arm 36 with the assigned actuating arm 42 is illustrated in more detail. In the upper end regions 46 located opposite the lower end regions 44, the actuating arms 42 are connected to the wrapping arms 36 in a pivotable manner via a joint 48 such that they run ahead of the wrapping arms 36 in operation. The lower end regions 44 are each provided with a covering 50 made of damping material, for example foam. However, this is not absolutely necessary.
According to the illustrations in figures 3 and 4, the emergency stop device 40 has a switching device 52 and an actuating device 54. The switching device 52 has a tensioning means 56 which acts on or is attached to the wrapping arm 36 at one end and the actuating
The frame 14 is formed by a welded and/or screwed assembly and is supported on the ground by means of the chassis 16. The chassis 16 is illustrated in the drawing in a tandem axle design with two axles 24, each of which is provided on each side with a wheel 26. A
configuration with only one axle or with support by means of crawlers or other suitable means is also conceivable.
The bale wrapping device 12 has a frame 30, a wrapping table or receiving apparatus 32 for receiving the bale 34 to be enveloped, and wrapping arms 36 which can be set in motion about an axis A by means of a suitable drive (not shown) in order to envelop the bale 34 with an enveloping material 38, for example a film, and an emergency stop device 40.
The emergency stop device 40 has actuating arms 42 which are each assigned to the wrapping arms 36. Lower end regions 44 of the actuating arms 42 extend substantially parallel to the actuating arms 42. In figure 2, to which reference is likewise made here, a wrapping arm 36 with the assigned actuating arm 42 is illustrated in more detail. In the upper end regions 46 located opposite the lower end regions 44, the actuating arms 42 are connected to the wrapping arms 36 in a pivotable manner via a joint 48 such that they run ahead of the wrapping arms 36 in operation. The lower end regions 44 are each provided with a covering 50 made of damping material, for example foam. However, this is not absolutely necessary.
According to the illustrations in figures 3 and 4, the emergency stop device 40 has a switching device 52 and an actuating device 54. The switching device 52 has a tensioning means 56 which acts on or is attached to the wrapping arm 36 at one end and the actuating
- 6 -, I
arm 42 at the other end. The tensioning means 56 is configured in the form of a mechanical tension spring, although other configurations of tensioning elements are perfectly possible.
The emergency stop device 40 and the actuating arm 42 cooperate in a known manner with a switching means (not shown), for example a switch that opens or correspondingly closes an electrical circuit, a sensor that interacts with a control or regulating device, or with suitable mechanical means, such that in the event that the actuating arm 42 is pivoted counter to the action of the tensioning means 56, in particular upon striking an obstacle, an emergency stop of the rotating wrapping arms 36 is executed. As a result of an emergency stop, in particular the driving of the wrapping arms 36 is suppressed, and furthermore/alternatively, a braking device (not shown) for the wrapping arms 36 can be activated and/or further functions of the wrapping device 12, a harvesting appliance 10 bearing the wrapping device 12 and/or a towing machine (not shown) can be suppressed and/or activated/triggered.
The actuating device 54 has an actuator 58 in the form of a hydraulic cylinder, which can be driven or accordingly charged with hydraulic fluid such that an angle a enclosed between the wrapping arm 36 and the actuating arm 42 and/or a spacing D between the wrapping arm 36 and the actuating arm 42, or the lower end region 44 thereof, is variable.
Reference is now made again to figure 3, according to the illustration of which a pivot lever 60 is provided which is connected in a pivotable manner to the joint 48 in a central region 62. In a region 64, remote from the axis A, of the pivot lever 60, a further joint 66 is provided, about which the actuating arm 42 is again connected to the pivot lever 60 in a pivotable manner. The actuator 58 acts on a region 68, facing the axis A, of the pivot lever 60 such that it can pivot the pivot lever 60 and thus also the actuating arm 42, connected to the pivot lever 60 via the joint 66, about the joint 48.
Reference is now made to figure 4, in which the reference signs in figure 3 have been adopted in a corresponding manner given the same configuration. If the embodiment differs from the illustration shown in figure 3, an a is added to the reference signs.
According to the illustration in figure 4, an actuator 58a of an actuating device 54 acts on the wrapping arm 36 at one end. In the embodiment illustrated in figure 4, the actuator 58a acts on the
arm 42 at the other end. The tensioning means 56 is configured in the form of a mechanical tension spring, although other configurations of tensioning elements are perfectly possible.

Reference is now made to figure 4, in which the reference signs in figure 3 have been adopted in a corresponding manner given the same configuration. If the embodiment differs from the illustration shown in figure 3, an a is added to the reference signs.
According to the illustration in figure 4, an actuator 58a of an actuating device 54 acts on the wrapping arm 36 at one end. In the embodiment illustrated in figure 4, the actuator 58a acts on the
- 7 wrapping arm next to the axis A and, as seen from above, beneath a drive for the wrapping arms 36. At the other end, the actuator 58a acts directly on a tensioning means 56a of the switching device 52a. The tensioning means 56a, likewise configured as a tension spring, again acts on the actuating arm 42 connected to the wrapping arm 36 via a joint 48a.
The actuating devices 54 according to figures 3 and 4 are each actively connected to a control device 70. The control device 70 cooperates with the actuator 58, for example by being charged in a corresponding manner with hydraulic oil, such that the angle a enclosed between the unactuated actuating arm 42 and the wrapping arm 36 and the spacing D
between the lower end region 46 of the unactuated actuating arm 42 and the wrapping arm 36 can be controlled and/or regulated thereby in particular in a state of the actuating arm 42 in which it is not actuated by the control device 70. However, the actuator can also be configured in the form of a mechanical connection, for example as a lever or linkage connection, as a push-pull cable, a spindle drive, an electrical drive, for example of the servomotor type or in any other suitable way. Actuation or regulation can take place automatically or manually.
Generally, in operation, a bale 34 is delivered by the harvesting appliance 10 after the end of the baling operation and is transferred to the bale wrapping device 12 by means of known means that are not illustrated in more detail. After the bale 34 has been received by the receiving device 32, the bale 34 is enveloped with enveloping material 38 by means of the wrapping arms 36.
While the bale 34 is being enveloped with enveloping material 38, the actuating arms 42 run ahead of the wrapping arms 36. If one of the actuating arms 42 comes into contact with an obstacle, for example with a person or an animal, who/which could be injured by the wrapping arms 42, or with an object, for example an object which could result in damage to the bale wrapping device 12, the harvesting appliance 10 or one or more constituents of the bale wrapping device 12 and/or of the harvesting appliance 10, the actuating arm 42 pivots counter to the action of the tensioning means 56, 56a and deactivates at least one function of the bale wrapping device 12 or of the harvesting appliance 10, in particular the driving of the wrapping arms 42, and activates preferably a braking device in order to brake the wrapping arms 36, or the movement thereof in rotation.
The actuating devices 54 according to figures 3 and 4 are each actively connected to a control device 70. The control device 70 cooperates with the actuator 58, for example by being charged in a corresponding manner with hydraulic oil, such that the angle a enclosed between the unactuated actuating arm 42 and the wrapping arm 36 and the spacing D
between the lower end region 46 of the unactuated actuating arm 42 and the wrapping arm 36 can be controlled and/or regulated thereby in particular in a state of the actuating arm 42 in which it is not actuated by the control device 70. However, the actuator can also be configured in the form of a mechanical connection, for example as a lever or linkage connection, as a push-pull cable, a spindle drive, an electrical drive, for example of the servomotor type or in any other suitable way. Actuation or regulation can take place automatically or manually.
Generally, in operation, a bale 34 is delivered by the harvesting appliance 10 after the end of the baling operation and is transferred to the bale wrapping device 12 by means of known means that are not illustrated in more detail. After the bale 34 has been received by the receiving device 32, the bale 34 is enveloped with enveloping material 38 by means of the wrapping arms 36.
While the bale 34 is being enveloped with enveloping material 38, the actuating arms 42 run ahead of the wrapping arms 36. If one of the actuating arms 42 comes into contact with an obstacle, for example with a person or an animal, who/which could be injured by the wrapping arms 42, or with an object, for example an object which could result in damage to the bale wrapping device 12, the harvesting appliance 10 or one or more constituents of the bale wrapping device 12 and/or of the harvesting appliance 10, the actuating arm 42 pivots counter to the action of the tensioning means 56, 56a and deactivates at least one function of the bale wrapping device 12 or of the harvesting appliance 10, in particular the driving of the wrapping arms 42, and activates preferably a braking device in order to brake the wrapping arms 36, or the movement thereof in rotation.
- 8 The spacing D or the angle a are intended to be adjustable or settable in order for it to be possible to adjust, set or adapt a delay between the actuating arm(s) 42 striking an obstacle of the person, animal and/or object type, in particular given different speeds (of rotation). If the wrapping device 12 or the wrapping arms 36 thereof is/are moving or rotating at a greater speed, the spacing D or the angle a can be increased, and reduced in the case of a lower speed. To this end, reference is now made to figure 5, in which the actuating arm is shown in correspondingly different positions with spacings D'; D", D", D", D"
and angles a', a", am, a", a" of different sizes. Provision can be made for the actuating arm 42 to be retained permanently in its respective position but it is also conceivable for the actuating arm 42 to take up a rest position in which it bears for example closely against the wrapping arm 36 when the bale wrapping device 12 is not in operation and/or when the bale wrapping operation is intended to be concluded, the enveloping material severed and/or the bale delivered from the bale wrapping device 12 or from the harvesting appliance 10.
It is also conceivable, as per the simplified illustration in figure 5, for no control device to be provided, such that the actuating arm 42 is configured such that, on account of the effect of a centrifugal force, it takes up a position that is predetermined with respect to the wrapping arm 36 or is determined by the intensity of the centrifugal force occurring.
To this end, the actuating arm 42 can cooperate for example with a suitable tensioning or spring means, for example in that it is pretensioned counter to the effect of the centrifugal force by the tensioning or spring means.
