Abstract

A packaging machine comprising a sealing station with a sealing tool, a side frame and at least a first as well as a second upper protective cover respectively for placement onto a top side of the side frame during the manufacturing operations, wherein each of the two protective covers form a body with a lid, multiple side walls as well as a bottom. In one embodiment, the two protective covers can be stacked on one another, wherein at least one of the two protective covers forms at least one stack stop on the lid to which an edge of the floor of the other protective cover can be coupled in a removable way if the two protective covers are stacked on top of one another. In one embodiment, the packaging machine may be a deep-drawing packaging machine or a tray-sealing machine.

First claim

What is claimed is:

1 . A packaging machine comprising:
a sealing station with a sealing tool; a side frame; and at least a first upper protective cover and a second upper protective cover, each of said first and second upper protective cover being disposed on a top side of the side frame during manufacturing operations; wherein each of the first upper protective cover and the second upper protective cover comprise a body with a lid, multiple side walls, and a bottom; wherein the first upper protective cover and the second upper protective cover are configured to be disposed in a stacked arrangement, wherein one of the first upper protective cover or the second upper protective cover is on top of the other one of the first upper protective cover or the second upper protective cover; and wherein said one of the first upper protective cover or the second upper protective cover includes at least one stack stop on the lid to which an edge of the bottom of the other one of the first upper protective cover or the second upper protective cover can be removeably coupled when the first upper protective cover and the second upper protective cover two protective covers are in said stacked arrangement.

2 . The packaging machine according to claim 1 , wherein the at least one stack stop is formed integrally on the lid of one of the first upper protective cover or the second upper protective cover.

3 . The packaging machine according to claim 1 , wherein the at least one stack stop is pressed into the lid of one of the first upper protective cover or the second upper protective cover using a reshaping process and forms a ledge.

4 . The packaging machine according to claim 1 , wherein the at least one stack stop comprises an indentation with an arc-shaped edge.

5 . The packaging machine according to claim 1 , further comprising a first plane that is taken up by the lid, said first plane being inclined in relation to a second plane that is taken up by said bottom.

6 . The packaging machine according to claim 1 , wherein the at least one stack stop comprises at least two elements, with at least one of the at least two elements disposed on opposite sides of the lid.

7 . The packaging machine according to claim 1 , wherein the bottom of one of the first upper protective cover or the second upper protective cover has at least partially a circumferential or perimeter flange that forms the edge for coupling to the at least one stack stop of the other one of the first upper protective cover or the second upper protective cover.

8 . The packaging machine according to claim 1 , wherein the lid of at least one of the first upper protective cover or the second upper protective cover forms a support surface for the floor of the other one of the first upper protective cover or the second upper protective cover stacked on it in the stacked arrangement.

9 . The packaging machine according to claim 1 , wherein at least the first upper protective cover and the second upper protective cover can be stacked on the top side of the side frame.

10 . The packaging machine according to claim 1 , wherein at least the first upper protective cover and the second upper protective cover can be stacked according to their orientation during the manufacturing operations when they are positioned on the top side of the side frame or in relation to this orientation in a way as to be twisted horizontally by 180°.

11 . The packaging machine according to claim 1 , wherein at least one of the first upper protective cover and the second upper protective cover comprise a twisting protection device so that the protective covers can only be stacked up according to their orientation during the manufacturing operations.

12 . The packaging machine according to claim 1 , wherein at least one of the first upper protective cover and the second upper protective cover are formed as one part.

13 . The packaging machine according to claim 1 , wherein the lid of at least one of the first upper protective cover and the second upper protective cover comprises a window.

14 . The packaging machine according to claim 1 , wherein the lid of at least one of the first upper protective cover and the second upper protective cover has a grip.

15 . The packaging machine according to claim 1 , wherein the at least one stack stop is a hand grip.

16 . The packaging machine according to claim 1 , wherein the packaging machine is one of a deep-drawing packaging machine or a tray-sealing machine.
