Abstract
The present invention includes a method and an apparatus (1) for handling flat material and/or film material wound onto rolls (5) and that serves as packaging material. Rolls (5), which are at least partially unwound, are alternately removed from at least one installation position (EB1; EB2) of a packaging machine (3), and in each case a new roll (5) of flat material and/or film material is mounted in the particular installation position (EB1; EB2). After each mounting, an externally arranged layer (15) is extracted from the particular new roll (5) near or in the area of its free end and is attached to a section of a material web being guided in the packaging machine (3). The direction of rotation and/or rotation-direction-conforming orientation of the new roll (5) is determined and/or verified by means of a capture device.

DETAILED DESCRIPTION OF THE INVENTION
(9) The same or equivalent elements of the invention are designated by identical reference characters. Furthermore and for the sake of clarity, only the reference characters relevant for describing the respective figure are provided. It should be understood that the detailed description and specific examples of the embodiments of the apparatus or of the method according to the invention are intended for purposes of illustration only and are not intended to limit the scope of the invention.

(11) The apparatus 1 serves for handling packaging material or, as the case may be, shrink film that is wound onto rolls 5. A packaging machine 3 being supplied new rolls 5 by way of a handling device 7 are discernible in
(12) As shown in a synopsis of
(13) The new rolls 5 are composed of packaging material or, as the case may be, of shrink film, as well as of a core 6, onto which the packaging material or, as the case may be, the shrink film is wound. For taking a new roll 5 from the horizontal conveying device 13, the handling device 7 dips into a core 6 on the face side of the new roll by way of a retaining mandrel 17. For this purpose, a gripping arm 8 of the handling device 7 can be rotatingly moved about an axis of rotation 16 as is exemplarily shown in
(14) New rolls 5 are supplied to the handling device 7 by way of the horizontal conveying device 13 such that another new roll 5 is moved further toward the handling device 7 or, as the case may be, moves up toward the handling device 7 when a new roll 5 is removed from the horizontal conveying device 13. The horizontal conveying device 13 can thus be operated in a clocked manner or continuously at a constant speed. The operation is specified by the control unit S.
(15) Also discernible is a manipulator 12 positioned in the area of the horizontal conveying device 13, which manipulator 12 is operated by a user 30, and by which manipulator 12 new rolls 5 are placed standing upright onto the horizontal conveying device 13. In this context it is conceivable that the user 30 places the new rolls 5 on the horizontal conveying device 13 already in a certain direction of rotation or, as the case may be, in an orientation conforming with a certain direction of rotation, with a later verification or, as the case may be, determination of the appropriate direction of rotation and/or the rotation-direction-conforming orientation of new rolls 5 serving for preventing disruptions of the packaging machine 3 caused by mounting with a wrong direction of rotation or, as the case may be, with a non-rotation-direction-conforming orientation. In further embodiments it is moreover conceivable that the new rolls 5 are placed on the horizontal conveying device 13 by the user 30 in a random direction of rotation or, as the case may be, rotation-direction-conforming orientation, and that the handling device 7 selects new rolls 5 with appropriate direction of rotation or, as the case may be, rotation-direction-conforming orientation and mounts them in the particular installation position EB1 or EB2, as the case may be, of the packaging machine 3. The new rolls 5 stand on a pallet 9, from which the user 30 takes them by the manipulator 12 and places them onto the horizontal conveying device 13. An operating range of the manipulator 12 therefore extends across the pallet 9 as well as across a conveyor line section of the horizontal conveying device 13.
(16) Further illustrated is a container 20, which is located in the operating range of the handling device 7. When the supply of packaging material or, as the case may be, of shrink film of one of the rolls 5 placed in the packaging machine 3 is depleted, the cellulose or plastic core 6 of an empty roll 5 is removed from the packaging machine 3 and deposited in the container 20 by the handling device 7. Only after removing the core 6 can a new roll 5 be mounted in the particular installation position EB1 or EB2, as the case may be, of the packaging machine 3 such that the handling device 7 first removes the core 6 and in temporal succession mounts a new roll 5 in the particular installation position EB1 or EB2, as the case may be.
(17) The horizontal conveying device 13, the handling device 7, and the packaging machine 3 are linked to a control unit S. In the present instance, the control unit S controls the clocked operation of the horizontal conveying device 13, initiates rolls 5 to be mounted in and removed from the two installation positions EB1 and EB2 by the handling device 7, and controls an unwinding of packaging material or, as the case may be, of shrink film from the rolls 5 mounted in the packaging machine 3, as is described in more detail below.
(18) The control unit S has a display or is moreover linked to a display, which is not illustrated here, by way of which information on the direction of rotation or, as the case may be, on the rotation-direction-conforming orientation of new rolls 5 are output in a manner visible to a user 30.

(30) As soon as the adhesive label 22 has been detected by way of the capture device 23, the pin 27 is rotatingly moved until the adhesive label 22 faces toward the oppositely located installation position EB1. Only after this alignment of the adhesive label 22 can a fixing rod 14, which is only illustrated in
(31) Further embodiments are conceivable, in which the new rolls 5 have no reflective adhesive label 22 and in which the capture device 23 or, as the case may be, the cameras 19 detect an externally arranged layer 15 of new rolls 5 or, as the case may be, the free end sections of new rolls 5 without an additional optical marking of the new rolls 5.

(35) The gripping arm 8 of the handling device 7 is pivotable about the horizontally oriented axis 16 such that the retaining mandrel 17 of the handling device 7 can be aligned with a vertical orientation of its longitudinal axis for the purpose of dipping into the core 6 of the particular new roll 5. If the particular new roll 5 has been seized by the handling device 7 or, as the case may be, by the retaining mandrel 17, the new roll 5 can be rotated about the axis 16 by another pivoting motion of the gripping arm 8 and can thereafter be mounted in its particular, associated installation position EB1 or EB2, as the case may be (cf.

Those skilled in the art will appreciate that numerous changes and modifications can be made to the preferred embodiments of the invention and that such changes and modifications can be made without departing from the spirit of the invention. It is, therefore, intended that the appended claims cover all such equivalent variations as fall within the true spirit and scope of the invention.
