    专利说明:

    The invention relates to a method for handling cheese loaves and a device for this purpose, which can be assigned in particular to a so-called cassette press with round or square cheese molds.
    A device for the industrial production of cheese loaves is z. B. known from EP-A-350777. This includes a flushing press with a rectangular and open-topped trough for receiving molds, a pillar frame for arranging a press head that can be raised and lowered and a distribution head for feeding and dosing the raw cheese mass into the molds and a gantry car that can be moved on the trough to guide the distribution head and for handling a turning mechanism for the molds. The distribution head and the turning mechanism must be provided manually, resp. change. EP-A-406899 shows a further development of such a device in which the molds are accommodated in cassettes which in turn are arranged compactly and in rows in the trough. Above the molds there is a pressing head with pressing rams aligned with the molds for pressing the raw cheese mass. The cassettes have a gap-minimizing edge design and a mechanized device is provided for pushing the cassettes.The tub can also be assigned a shelf for second molds in which the pressed raw cheese loaves are reloaded (EP-A-1769676). The second molds can be fed to a further work section by means of a roller conveyor device of a corresponding handling device of the press.
    According to EP-B-543185, a mold cover can be connected to the ram via a tilting device (self-centering), so that suction of the mold cover on the cheese fair is avoided as a result of possible tilting movements. The shape itself is round or square and can consist of an outer container and an inner, perforated shell.
    The pressed cheeses can be removed from the mold, for example by means of a gripper, with air being blown into the mold beforehand in order to release the cheese from the mold wall (EP-B-1269832 or DE-B-922448).
    [0005] Contact of the cheeses with blown air or other gases can pose a sanitation problem. In order to avoid this, attempts were also made to remove cheese loaves from the press mold using a vacuum gripper. However, this leads to the formation of cones or, in general, to damage to the surface or even to tearing of the loaf.
    Another such cassette press is published in CH704208A2 and EP2710888A1. The cassette press according to CH704208A2 has two handling devices, the second handling device, which can be moved along the longitudinal sides of the trough, corresponding to a turning unit.EP2710888A1 discloses a cassette press provided with a vibrating unit associated with a horizontally arranged deposit or conveyor for the pressed cheese loaves.
    The invention is based on the object of developing a method for the automatic handling of cheese loaves with which, in particular, gentle, fast and precise demoulding/molding of the cheese loaves from a primary form into a secondary form can be achieved.
    The object is achieved with the features of patent claim 1. A raw cheese mass is pressed in molds of a cassette press, the pressed raw cheese mass is then released from the inner wall of the mold, the mold is rotated and lowered, and the mold is emptied by shaking or blowing it out.
    A pick-up stamp moves into the rotated form up to the wheel of cheese, with the form resp. the cassette with the mold is rotated and lowered and, after shaking or blowing out, the pick-up stamp with the cheese wheel lying on it moves out of the mold, b) the mold without the cheese wheel lying on it is lifted accordingly, rotated by 180° and inserted into the cheese press, in particular one Cassette press is returned, c) the pick-up stamp with the cheese loaf lying on it is now lowered, and d) the cheese loaf is fixed on the pick-up stamp by means of a clamping unit, e) so that the cheese loaf can be swiveled through 180° to a secondary mold and guided into it, and then f) the clamping unit is opened and the pick-up stamp is rotated and retracted.
    The detachment of the wheel of cheese, respectively. the raw cheese mass from the inner wall of the mold is carried out by shaking or blowing out the pressed cheese loaf directly, respectively. directly before demoulding. The shaking movement is initiated immediately after the mold has been turned over, so that each wheel of cheese can then rest on a pick-up stamp.
    A specification of the method according to the invention is disclosed in the dependent claims.
    The shaking is only for a short time and at least once.The shaking movement can be horizontal or vertical. The mold is preferably lowered into a vibrator.Each wheel of cheese is pushed into the secondary mold with the pick-up stamp and the wheel of cheese is pivoted preferably with a pivoting gripper or a turning gripper. Here, the pivoting or turning gripper turns back by 180° to its starting position after the pick-up stamp has been retracted.
    The cheese loaves are not only removed from the mold gently but also hygienically and transported further.
    Another object is to provide a device for handling cheese loaves that allows for quick transfer of cheese loaves. This problem is solved with the features of patent claim 7 .
    Preferred embodiments are disclosed in the dependent claims.
    The inventive device is compact and allows automated handling and gripping in particular of the cheese loaves and thus a rapid reassignment of the cassette press, since the cheese only has to linger a short time in the molds.
