Funktionsteilaufnahmeanordnung 4 a drive 9, which may be motor or manually executed, provided with the rotational and / or linear movement of the

Functional part receiving arrangement is driven relative to the frame 5. Furthermore, the functional part receiving arrangement 4 at least one transport surface 7, 8, here two transport surfaces 7, 8, which on the structure 1 1 of the functional part receiving arrangement 4 is arranged. On / on the transport surface 7, 8, the functional part 2 is stored. This transport surface 7, 8 is provided relative to the structure 11 of the functional part receiving arrangement 4 in at least one, here two, in particular mutually perpendicular spatial directions movable. As a result, the transport surface 7, 8 can be moved away to the packaging machine and away from the packaging machine, in the horizontal direction, and the transport surface 7, 8 can be aligned in the vertical direction relative to the packaging machine, both of which can be seen in particular FIG. The horizontal movement of the transport surface 7, 8 of the functional part receiving arrangement 4 is preferably driven manually. The vertical movement of the transport surface 7, 8 relative to the structure 11 of the functional part receiving arrangement 4 can be done manually or by motor. In the present case, the motor drive is performed by a toggle lever 20 which is provided between the structure 1 1 and the transport surface 7,8. Furthermore, it can be seen that the device according to the invention at the front end 12 of the structure 11 of the functional part receiving arrangement 4, ie the end 12, in the direction of

Packaging machine shows a means 6 for docking the

Functional part receiving arrangement has. This means will be explained in detail with reference to FIG. Furthermore, it can be seen in particular from FIG. 1 that the transport surface 7, 8 has a guide means 13, here two guide grooves. Get into these grooves

Fortsätze 14, which are arranged on the functional part 2, in particular the tool, a, so that the functional part 2 in its adoption to the inventive

Device 1 or at its delivery to the packaging machine 3 is guided on the one hand and on the other hand, the distance between the means 6 and the functional part, which lies on the device, is clearly defined.

FIG. 3 shows the device 1 according to the invention in interaction with a device

3. The packaging machine is preferably a so-called form, fill, seal device in which initially a packaging tray is formed in a lower film web, this packaging tray is then filled and the

Packaging tray is then closed with a lid film. During this

Operation is the film web by means of the transport chains 24 along the

Packaging machine 3, which has a frame 23 transported. These

Packaging machine 3 has a forming and / or a sealing tool 2, which must be changed when the packaging machine for the production of another

Packaging or other format must be converted to packaging. For this, the device 1 is placed next to the packaging machine in the region of the docking means 27, which are provided on the packaging machine 3, in particular its frame 23, so that the means 6 for docking the functional part receiving arrangement 4 above the means 27 are located. Then, in particular, the front end 12 of the structure 1 1 of the functional part receiving arrangement 7 is lowered. This can be done by pivoting and / or rotating the functional part receiving arrangement 4 around the bearing 10. The means 6 each engage in a means 27 and the device 1 according to the invention is characterized by the V-shape of both the means 6 and the means 27, which will be explained in more detail with reference to Figure 4, in two spatial directions X, Y. aligned. Furthermore, in this orientation, a rotation of the

Functional part receiving arrangement 4 take place, in the event that the means 27 are not provided completely horizontal to each other. Thereafter, the rear end 28 of the structure 11 of the functional part receiving assembly 4 is raised or lowered until the transport surface 7, 8 is in a horizontal position. This turns the

Functional part receiving arrangement 4 about a virtual axis of rotation, which is spanned between the two means 27. The skilled person understands that the horizontal alignment of the transport surface 7, 8 can also be effected by a movement of the transport surface 7, 8 relative to the structure 1 1 of the functional part receiving arrangement 4. The transport surface 7, 8 is now arranged completely parallel and horizontal to the frame 23 of the packaging machine 3, so that the tool 2 can be transferred to the device 1 in a simple manner. This is done by the transport surface 7,8 first in a

desired height is brought. This can be done manually or by motor with the drive 20. The vertical movement of the transport surface 7, 8 relative to the structure 11 of the functional part receiving arrangement 4 is symbolized by the double arrow 21. Thereafter, the transport surface, as shown by the arrow 22, in the direction of

Packaging machine 3 is moved and reversibly connected to this. By aligning the device 1 relative to the frame of the packaging machine 23 by means of the means 6, 27 and by the horizontal orientation of the transport surface 7, 8 now the tool 2 can be easily pulled onto the transport surface 7,8. In this case, roll / guide means 14 engage in recesses 13, here grooves, so that the tool 2 is guided in its movement onto the transport surface 7, 8. As soon as the tool 2 has been drawn sufficiently far onto the surface 7, 8, fastening / locking means 18 prevent the tool 2 from unintentionally slipping off the surface 7, 8. An exchange tool (not shown) may be positioned at level 8. This level 8 will then be in the

desired transfer height brought and the tool can be transferred from the level 8 to the packaging machine. To facilitate this transfer, guiding means 16, here grooves, are arranged on the lifting table 15, on which the tool 2 is mounted in the packaging machine 3, also grooves, which are arranged by the alignment of

Funktionssteilaufnahmeanordnung 4 relative to the packaging machine 3 with the Guiding means 13 of the transport surface 7, 8 are aligned. As a result, a simple guided transfer of the tool 2 is possible.

Figure 4 shows the means 6, 27. The means 6 is located at the front end 12 of the structure 11 of the functional part receiving arrangement 4 and is designed V-shaped. The means 27 is arranged on the frame 23 of the packaging machine 3 and also designed V-shaped.

Preferably, the surfaces of the V are concave. Due to the interplay of the two V-shapes, the structure 1 1 of the functional part receiving arrangement 4 takes a clear position relative to the frame 23 of the packaging machine in two

Spaces, which are represented here by the coordinate system X, Y a. In this process, the functional part receiving assembly 4 can rotate about the Y axis.

Figure 5 shows an embodiment of the tool 2 according to the invention, which has at least one here a plurality of rolling / guiding means (s) 14 on its underside. By this means 14, the tool is guided in the transfer of the inventive device to the packaging machine and vice versa. The tool is reversibly locked after its transfer to the lifting table 15 (see FIG.

FIG. 6 shows the lifting table 15 of the packaging machine 3 according to the invention. This has at least one guide means 16, in this case guide grooves, into which the rolling / guiding means 14 of the tool 2 engage, so that the tool is in its position
