(12) The apparatus for processing food products shown in FIGS. 1 and 2 and designed in accordance with the prior art comprises a product conveyor 11 and a work unit 13 in the form of an automatic packaging machine. The product conveyor 11 comprises a base rack or a frame 15 and a conveyor unit 17 fixed to the frame 15. The conveyor unit 17 comprises one or more belt or strap conveyors and is, as shown, arranged laterally projecting at the frame 15. The work unit 13 is located beneath the conveyor unit 17 and likewise comprises a base rack or a frame 19 which is here composed of cross members 21 having section-like side carriers 23 attached thereto. A supply and control unit 24 in the form of a switch cabinet is attached to the side of the frame 19 of the work unit 13 at the right in FIG. 1. Both the product conveyor 11 and the work unit 13 are positioned on the floor 27 by means of feet.

(13) The apparatus shown in FIGS. 1 and 2 is integrated into a production line for packaged foods and serves to package product portions sliced by a high-performance slicer, not shown, by format set. The product conveyor 11 is accordingly provided to convey delivered product portions in a conveying direction extending at a right angle to the plane of the drawing and to feed them into an arrangement of packagings provided by the work unit 13. The work unit 13 provides an arrangement of packaging depressions at a transfer section 28 of a provided plastic film web by means of a deep-drawing process. After the feeding of the product portions, the packaging depressions are closed by a likewise provided plastic film web. A protective cover 29 is located above the transfer section 28.

(14) To ensure an easy and safe access to the work unit 13 for conversion work, repair work or servicing work, a housing 30 of the conveyor unit 17 is supported at the frame 15 pivotable about a pivot axis S. It can thus be pivoted, starting from the lowered operating position shown in FIG. 1, into the raised maintenance position shown in FIG. 2.

(15) In the apparatus in accordance with the invention for processing food products shown in FIGS. 3 to 5, the product conveyor 31 and the work unit 13 are not designed as machines to be installed separately, but are rather merged into one unit. Specifically, the frame 35 of the product conveyor 31 is fastened, as shown, to the work unit 13 at a spacing from the base 27. This means that the product conveyor 31 is completely carried by the work unit 13 and is supported thereat both in the horizontal direction and in the vertical direction. The mass and the stiffness of the work unit 13 is sufficient to give the total unit stability. The conveyor unit 37 of the product conveyor 31 is likewise pivotable in the embodiment of the invention shown in FIGS. 3 to 5 between a lowered operating position and a raised maintenance position. The conveyor unit 37 is here, however, configured as a conveyor belt unit in which the shafts of the corresponding belt conveyor or strap conveyor are supported. A pivotable housing of the conveyor unit 37 can thus be dispensed with.

(16) As in the embodiment shown in FIGS. 1 and 2, a protective cover 39 is arranged above the transfer section 28 of the work unit 13. As required, the protective cover 39 can, however, be fastened or fastenable to the lower side 40 of the conveyor unit 37 so that it is pivotable together with the latter between the operating position and the maintenance position (FIG. 5). In the maintenance case, a workstep can thus be saved. The protective cover 39 in the apparatus in accordance with the invention shown in FIGS. 3 to 5 additionally serves as a collection apparatus for collecting those particles which fall down from the conveyor unit 37. The work unit 13 is thus also protected against cleaning fluid when the product conveyor 31 has to be cleaned intensively at regular intervals for hygiene reasons.

(17) A variant of this embodiment is indicated by a broken line in FIG. 3. This variant is not shown for reasons of simplicity in FIGS. 4 and 5. In accordance with this variant, the frame 35 has an arm 67 configured as a horizontally projecting frame region. The arm 67 starts from the vertically extending frame region at the one side of the work unit 13, extends along the lower side of the work unit 13 to the oppositely disposed side and is fixed there. The work unit 13 is gripped around, in particular in the form of a clamp, by the frame 35 in this manner. With this support or holding of the product conveyor 31 at the work unit 13, a particularly uniformly distributed force introduction via the frame 35 of the product conveyor 31 into the work unit 13 can be achieved in an advantageous manner. Additional feet are also not required in this variant.

(18) FIGS. 6 to 8 show an alternative embodiment of an apparatus in accordance with the invention for processing food products. The apparatus likewise comprises a product conveyor 41 as well as a work unit 13, but differs from the above-described embodiment to the extent that the frame 45 of the product conveyor 41 is configured as a carrying rack. The frame 45 of the product conveyor 41 specifically comprises a vertical carrier section 47 as well as a horizontal standing section 49. The frame 45 therefore has, as can be recognized in the Figures, a substantially L-shaped cross-section. The width of the standing section 49 is greater than the width of the laterally projecting conveyor unit 37 so that a sufficient stability is ensured for the product conveyor 41. The stand section 49, however, only has a small construction height so that it can be arranged reaching into the free space 60 formed between the feet 25 of the work unit 13. Although the product conveyor 41 is stable per se, the width of the total apparatus can be reduced with respect to the arrangement shown in FIGS. 1 and 2. If required, the standing section 49 can be fastened to the work unit 13 for additional stabilization.

(19) As in the embodiment shown in FIGS. 3 to 5, the conveyor unit 37 is also configured as a conveyor belt unit in the embodiment shown in FIGS. 6 to 8 and is pivotable between a lowered operating position (FIG. 6) and a raised maintenance position (FIGS. 7 and 8). In accordance with FIG. 8, the protective cover 39 is in turn fastened or fastenable to the lower side 40 of the conveyor unit 37.

(20) In the embodiment of an apparatus for processing food products in accordance with the invention shown in FIGS. 9 and 10, the frame 55 of the product conveyor 51 is supported both at the floor 27 and at the work unit 13. The frame 55 is specifically fastened to one of the side carriers 23 by means of a connection element 65, for example is screwed thereto. Due to this fastening, the frame 55 does not necessarily have to be stable per se so that it can be designed correspondingly lighter and smaller. The conveyor unit 37 is also configured as a conveyor belt unit in the embodiment shown in FIGS. 9 and 10 and is pivotable between a lowered operating position (FIG. 9) and a raised maintenance position (FIG. 10). The protective cover 39 can in turn, as required, be fastened to the lower side 40 of the conveyor unit 37, which is, however, not shown in FIGS. 9 and 10.

(21) A substantially lighter and more compact construction for the processing apparatus as a whole can be achieved by the inclusion of the work unit 13 to be arranged beneath the conveyor unit 37 into the support construction of the frame 35, 45, 55 of the product conveyor 31, 41, 51—whether in the form of a direct mechanical support connection and/or by direct utilization of a free space defined by the work unit 13.
