Wrapper for a baler and method of controlling the same

Abstract

The invention relates to a packager for a press-baler and a method for controlling the packager. The packager comprises a frame provided with a connection member connected to a farm implement at the front side thereof, a table installed at the central portion of the frame and used for rotating a bale to be packaged, a packaging arm installed on arc support elements fixed at the two opposite sides of the front portion of the frame, a packaging material stretcher installed in the packaging arm and used for extending a packaging material, thus enabling the packaging material to properly execute a packaging operation, a loader installed at the two opposite sides of the table, and used for supplying the bale to be packaged and discharging the packaged bale from the packager, and a film retainer installed at the two opposite sides of the frame, and used for cutting the packaged packaging material and retaining the end portion of the packaging material until the next packaging operation is carried out.

Description

technical field [0001] The present invention relates to a wrapper for a baler, and more particularly to an improved wrapper for a baler by stopping in place after the wrapping operation is complete while at a constant speed Performing the wrapping operation independently of the rotational speed of the implement to which the wrapper is attached enables the post-baling process to be simplified. Background technique [0002] Straw or fodder crops are stored on livestock farms during the winter to be used as fodder for livestock. However, when straw or forage crops are harvested and dried and kept in open fields, their freshness deteriorates over time and they dry out completely. Therefore, they are difficult for livestock to swallow and even if they are successfully swallowed by livestock they are of low value as feed due to their low nutrition. [0003] In order to solve this problem, a method and apparatus for forming harvested forage crops into a columnar bale shape after ...

Problems solved by technology

[0012] Furthermore, since the speed of the table and the wrapping arm is related to the speed of the tractor, when the wrapping arm starts to rotate, performs the wrapping operation and stops, the wrapping arm does not stop at the normal proper position but frequently stops at the wrong position

[0013] In this way, the packaging material cannot be cut and held when the packaging arm does not stop at the normal position, stops at the wrong position, and stops at the position of the film holder or the loading arm due to the inconstant rotational speed of the table and the packaging arm

Furthermore, the operations of positioning the bundle to be wrapped on the table and ejecting the wrapped bundle are not possible

[0014] For this reason, since the operator would experience the inconvenience of having to periodically move the packaging arm to the normal position and control the cutting of the packaging material and the discharge and supply of the bundle, the operation is performed slowly and operational fatigue increases
