ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the invention
The invention relates to a machine for removing circular labels or shrinkwrap from bottles or similar items.
2. Description of the Related Art
A similar machine is known from the international patent application WO 95/32 814. This machine has a rotary table with cutting tools for cutting through the circular labels or sleeves and a separate chain conveyer to keep the bottles away from the floor. On the chain conveyer are blast nozzles for loosening the labels from the bottles.
BRIEF SUMMARY OF THE INVENTION
The object of the invention is to provide a compact machine that does not take up much space for removing the circular labels or shrinkwrap from bottles and similar items.
The object is achieved by providing for the circular labels or shrinkwraps a separating or perforated line at the feed part of the machine.
This solution has the advantage that the carousel of the machine can be used for loosening the labels or sleeves, and in this way the chain conveyer used by the generic machines can be left out without a substitute.
The carousel is designed, i.e., equipped, with appropriate holding mechanisms, so that the bottles can be held hanging by the area around the head free of the floor. The devices required to loosen the labels, e.g., the spray nozzles, are set up on the circular path of the carousel.
According to an advantageous embodiment of the invention, the cutting tools necessary to create the separating line or perforated line in the labels are set up in the feed wheel of the machine, or integrated into this.
Advantageous further developments of the invention are indicated in the subclaims.
Details of a preferred embodiment of the invention as shown in the figures are given below. The figures show the following:
