Apparatus for the track individual provision of sheet material for placing underneath

1. An underlay apparatus for placing material under product on each of two or more tracks of a food processing line, comprising:

a product outfeed comprising the two or more tracks of the food processing line;

a product feed configured to transport the product to the product outfeed; and

an output unit, comprising:

a draw-in device for drawing in sheet material from a material web;

a separation device for separating the sheet material; and

an ejection device configured to receive the sheet material from the separation device and discharge the sheet material onto each of the two or more tracks, the ejection device comprising:

an ejection roller;

an ejection counter-unit; and

an ejection gap formed by the ejection roller and the ejection counter-unit and associated with each of the two or more tracks.

2. The underlay apparatus of claim 1 , wherein the draw-in device comprises a draw-in shaft for each of the two or more tracks.

3. The underlay apparatus of claim 2 , wherein the draw-in device further comprises:

a draw-in pressure unit comprising at least one pressure roller, the draw-in pressure unit and the draw-in shaft forming a draw-in gap,

wherein the draw-in shaft rotates the at least one pressure roller to draw in each material web into the output unit.

4. The underlay apparatus of claim 3 , wherein the draw-in pressure unit and the draw-in shaft are configured to intermittently engage to draw in the sheet material from the material web through the draw-in gap.

5. The underlay apparatus of claim 1 ,

wherein the material web is stored in a loop, and

wherein the output unit further comprises a sensor configured to detect a size of the loop.

6. The underlay apparatus of claim 1 , further comprising a removal shaft configured to receive the material web.

7. The underlay apparatus of claim 1 , wherein the separation device comprises at least one blade unit configured to at least perforate the sheet material to separate the sheet material.

8. The underlay apparatus of claim 1 , wherein the ejection counter-unit is pneumatically actuated to form the ejection gap, thereby entraining the sheet material to eject the sheet material onto the two or more tracks.

9. An underlay apparatus for placing material under products fed along two or more tracks, comprising:

a product feed configured to feed the products along the two or more tracks to a sheet feed region;

a product outfeed configured to transfer the products away from the sheet feed region on the two or more tracks; and

an underlay unit, comprising:

an ejection device configured to discharge sheet material from at least one material web onto each of the two or more tracks of the product outfeed, the ejection device comprising:

an ejection roller jointly associated with the two or more tracks;

an ejection counter-unit; and

an ejection gap formed by the ejection roller and the ejection counter-unit.

10. The underlay apparatus of claim 9 , wherein the underlay unit further comprises:

a draw-in device configured to draw in the sheet material from the at least one material web; and

a separation device configured to separate the sheet material from the at least one material web,

wherein the ejection device receives the sheet material from the separation device.

11. The underlay apparatus of claim 9 , wherein the ejection device has an ejection speed synchronized with a conveying speed of at least one of the product feed or the product outfeed.

12. The underlay apparatus of claim 11 ,

wherein at least one of the product feed or the product outfeed comprises at least one conveyor belt, and

wherein the ejection speed is synchronized with the conveying speed via a mechanical coupling of the ejection device to at least one of the product feed or the product outfeed.

13. The underlay apparatus of claim 9 , wherein the at least one material web for each of the two or more tracks is stored in a loop, and further comprising:

a sheet material detection sensor for detecting a size of the loop.

14. The underlay apparatus of claim 13 , wherein a provision speed of the sheet material is controlled based on the size of the loop.

15. A modular underlay apparatus for placing sheet material beneath products of a food processing line, comprising:

a draw-in module configured to draw in sheet material for each track of the food processing line;

a separation module configured to separate the sheet material into individual sheets; and

an ejection module configured to eject each of the individual sheets onto a respective track of a product outfeed; and

an output unit housing arranged beneath the food processing line and configured to receive each of the draw-in module, the separation module, and the ejection module.

16. The modular underlay apparatus of claim 15 , wherein each of the draw-in module, the separation module, and the ejection module are arranged in a separate housing.

17. The modular underlay apparatus of claim 15 ,

wherein the ejection module comprises a single drive unit, and

wherein each of the separation module and the draw-in module comprises one drive unit for each track of the food processing line.

18. The modular underlay apparatus of claim 15 , further comprising:

a material provision module configured to store a material web for each track of the food processing line, wherein the draw-in module draws in the sheet material from the material web.

19. The modular underlay apparatus of claim 15 , wherein the ejection module is mechanically coupled to the product outfeed such that an ejection speed of the ejection module is synchronized with a conveying speed of the product outfeed.

20. The modular underlay apparatus of claim 15 ,

wherein the output unit housing is received within a holding apparatus of the modular underlay apparatus, and

wherein the output unit housing is removable from the holding apparatus.
