Definitions

  • the invention relates to a method and a device with the features in the preamble of the main method and device claim.
  • the invention solves this problem with the features in the main method and device claim.
  • the invention provides for a defined fold to be formed in the corner regions of the cover sheet when the cover sheet is applied to the side surfaces of the press bale, and this then fold over with an equally defined movement and place it on the bale or the already folded lateral film web. In this way, the entire cover film is wrapped around the head region of the press bale as a flat wrapping. Due to the defined formation and end position of the fold in the corner area, this cannot be released later. The packaging remains tight and the bale is protected. A strapping length is also sufficient. Cross strapping is not necessary.
  • the formation and folding of the fold can be carried out in the same way with the upper and the lower cover film.
  • the fold is preferably folded over to the broad side of the bale, since it is fixed there directly by the strapping that is usually placed around the broad sides. Due to the strapping and the exact formation of folds, the upper edge of the bale is also held down better, which otherwise sometimes has a tendency to bulge after the press rams are relieved.
  • the fold is braced by an oblique downward and inward counterforce that counteracts the bulge and fixes the edge of the bale.
  • the fold In order to secure the fold position until strapping, the fold is temporarily held by a folding finger. If the strapping or other bale fixings are not placed over the broad sides of the bale, but in a different way with different packaging techniques, the fold is shaped and folded accordingly, so that it is ultimately held in the same way by the final bale fixation.
  • the folds are formed by a movable folding frame, which can be designed and moved in different ways.
  • the folding frame is once rigid Scraper frame with molded-out streak openings for the folds.
  • This embodiment is particularly suitable for the lower cover film, since the Streifgesteil can be connected to the press box and removed. As a result, the cover sheet is folded and folded over with the box trigger. This means that there is no need for a separate drive for the folding frame.
  • the squeegee can also be used to fold up the top cover film. It is then multi-part and movable to make room for the pulled box and then to be closed again for the folding function around the bale.
  • the second variant provides a multi-part folding frame, which consists of several rakes, which are movable in several axes and can carry out a horizontal and vertical movement in the preferred embodiment.
  • This type of construction is preferably used for turning over the upper cover film, but is also suitable for the lower cover film.
  • the folds are shaped here by the vertical lowering and horizontal movement of the rake.
  • the folding fingers for folding the folds are part of the rake here and can also support the formation of wrinkles by means of an additional transverse movement.
  • the method according to the invention and the associated device are particularly suitable for use on carousel balers in which the packaging is carried out within the baler.
  • it can also be used in other constructions, for example with external packaging stations, where the press bales are moved from the press into the packaging station with the press rams applied.
  • the method according to the invention and the associated device require little construction effort and are particularly economical. They can also be retrofitted to existing balers or packaging stations or exchanged for existing handling devices.

  • the lowered press box (5) is filled with fiber material, tow or the like other flowable and pressable goods, optionally pre-pressed and then rotated into the second station.
  • the final pressing and packaging of the bale (4) takes place here.
  • the lower press rams (3) are arranged on a yoke beam and can only rotate horizontally with it, but not perform lifting and lowering movements.
  • the upper press ram (2) is moved up and down by the piston rod (23) of a hydraulic drive (not shown).
  • the bale (4) which is still under pressure, is packaged.
  • the press box (5) is pulled upwards using a suitable lifting device.
  • a cover film (7) is placed on the lower press ram (3) and held.
  • the lower cover film is referred to below as the base film (7).
  • the upper cover film (6) hereinafter referred to as the head film, is placed on the material to be pressed in the press box (5) before the finished pressing and is carried along by the lowered upper press ram (2).
  • the head film (6) and the bottom film (7) are wrapped around the press bale (4) in the manner described below and lie tightly against it like a cap. Then a bandage is placed around the baling pad (4), which overlaps the cover foils (6, 7). The foils are finally fixed by a strapping device (17), a single strapping over the broad side (19) of the press bale (4) being sufficient.
  • Folding devices (8) are used to fold the cover foils (6, 7) around the head or foot region of the baling press (4), one of which is assigned to the upper press ram (2) and one to the lower press ram (3).
  • Two embodiments are shown for the folding device (8), of which FIGS. 2 to 5 show the variant for the base film (7) and FIGS. 6 and 7 the variant for the head film (6). Both embodiments can also be interchanged with a corresponding structural redesign. Alternatively, only one variant in double Execution are used.

  • Fig. 5 illustrates the streak frame (14) in plan view.
  • the stripping frame (14) has an I-shape and encloses the baling bale (4) on the side. There is a certain distance from the side surfaces of the press bale (4) in order to make room for the base film (7).

These extend laterally and as an extension of the narrow sides (18) of the press bale (4) to the outside. They have the task of forming a defined fold (9) protruding to the side in the bottom film (7) at the corners.
  • the stripping frame (14) When the bale (4) is finished pressing, the stripping frame (14) is located at the height or below the lower press ram (3).
  • Fig. 2 shows a position after completion of the pressing process, in which the press box (5) with the stripping frame (14) has already been raised a little in the direction of movement (20).
