- the object of the invention is the development of a bale opener with an improved arrangement of a pickup on the machine frame of the bale opener.
- the invention includes the technical teaching that the at least one traction means is guided around a deflection roller arranged on the upper side of the machine frame, wherein a first end of the traction means is connected to the traction unit and a second end of the traction means is mounted on a traction mechanism roller arranged on the traction unit. and unwindable, wherein the drive motor is arranged on the pickup unit and operatively connected to the traction means role.
- the core idea of the invention is the suspension of the pickup unit at the top of the machine frame via a looped traction means, which wraps around an associated deflection roller on the upper part of the machine frame.
- the drive motor arranged on the pickup unit can be moved vertically with the pickup unit. In a sense, in a vertical process with the pulling means itself, the picking unit pulls itself up against the machine frame when the drive motor is activated.
- the drive motor is operatively connected to the Buchstoff role, so that it can be set in rotation.
- the traction mechanism pulley is rotated by the drive motor in a direction in which the traction means is wound onto the traction mechanism pulley, and if the removal unit is to be moved vertically downwards, the traction mechanism pulley is rotated by the drive motor in a reverse direction so that the traction means is unwound from the traction pulley again.
- bale opener Due to the arrangement of the drive motor on the pickup unit itself eliminates the arrangement of the drive motor on the upper side of the machine frame, so that the overall height of the machine frame can be reduced accordingly. The design effort of the machine frame itself is reduced, since no laterally arranged in the side cheeks of the machine frame traction means must be driven.
- An advantageous embodiment of the bale opener provides that the machine frame has a first side cheek and an opposite second side cheek, wherein the pickup unit and the traction means are arranged substantially and in particular completely in a space between the two side cheeks.
- two parallel portal profiles are formed between the side cheeks, which are part of the machine frame, and which extend in a transverse direction and which are connected with their ends in the region of the upper corners of the side cheeks to this.
- the deflection roller can be arranged on the portal profiles around which the respective traction means is looped around.
- two traction means are provided for receiving the pickup, so that two pulleys are arranged on the upper side of the machine frame.
- two bridge elements are provided which are spaced from one another and preferably in the end regions of the portal profiles, with which they are connected to the side walls, arranged on the portal profiles and, for example, these are placed on top.
- the bridge elements are either C-shaped or trapezoidal-shaped and load with two opposite end sides on the top side on the portal profiles.
- the deflection rollers are accommodated centrally on the bridge elements, so that they are preferably centered over the spaced parallel running portal profiles. Consequently, that too respective traction means are arranged centrally on the machine frame, so that the pickup unit can be guided substantially torque-free on the machine frame.
- the pickup unit is suspended on two traction means, wherein the traction means are arranged close to the transversely lying end sides of the pickup unit and wherein the traction means rollers are arranged on a common drive shaft.
- the distance between the Switzerlandstoffrollen preferably corresponds to the distance between the pulleys, and the first ends of the traction means are also connected to the same distance to the pickup unit. If the drive motor is activated, both traction mechanism rollers rotate with the same rotational movement, and consequently both traction means of the same length can be wound onto the traction mechanism rollers. This ensures that the pickup unit has a horizontal extent at any altitude.
- the drive motor is connected with particular advantage by means of a transmission with the drive shaft.
- the transmission can be designed so that the drive shaft extends through a receiving opening through the transmission, so that a first traction roller is received on a first side of the transmission on the drive shaft and a second traction element on an opposite second side of the transmission on the drive shaft is included.
- the pickup unit has a brake unit which is connected to the drive motor.
- the brake unit is arranged on the drive motor, in particular on a motor rear side, wherein the transmission is arranged on an engine front side.
- the drive motor, the transmission and the brake unit form a structural unit.
- the structural unit has at the transmission output on a through opening through which the drive shaft can be passed.
- the drive shaft is connected to transmit torque to a driven gear of the transmission.
- the pickup unit when switching on the bale opener, can be moved to a reference position so that, starting from the reference position, the height position of the pickup unit can be detected via the rotation sensors and made available to an electrical control unit.
- the rotary sensor can serve, for example, as a control loop element for regulating the vertical traversing speed.
- connection of the first end of the traction means to the take-off unit comprises a force detection unit with which a tensile force can be detected in the traction means. Since the weight of the pickup unit is known, a support force of the pickup unit can be calculated on the fiber bales by a current detection of the tensile force in the traction means, in particular with the electrical control unit. Presses the pickup with a larger supporting force on the top of the fiber bales, the tensile force in the traction means is reduced, the difference between the weight of the pickup and the determined tensile force in the traction means, the supporting force of the pickup unit can be calculated on top of the fiber bales.
- a preferred variant for the formation of the traction means results when these are formed from drawstrings of a rubber material with integrated Stahlzugamban.
- drawstrings are known for example from the elevator construction for receiving a cab and mechanically highly resilient.
- the drawstrings have a very large transferable tensile force, which can be wound up at the same time with very large repetition numbers on Buchstoffrollen.
- traction means are maintenance-free and structurally easier to integrate in the bale opener than, for example, a chain drive.
- vertically oriented guide profiles are arranged on the inner sides of the side cheeks facing the pickup unit, on which the pickup unit can be moved vertically.
- the guide rollers which roll on the guide profiles, for example, on two side surfaces and / or on an end face and with which the pickup unit is guided on the guide profiles thus in a simple manner very accurate.
- the guide profiles are merely attached to the inner sides of the side cheeks and protrude slightly into the space between the two side walls and thus point opposite each other.
- the guide rollers which cooperate with the guide profiles for guiding the pickup unit, are located only on the outer sides of the pickup unit and form the same in the transverse direction.
