Device for compressing of empty deformable containers

摘要

An apparatus for compressing empty containers, in particular of beverage bottles or beverage cans made out of plastic, in particular out of polyethylene terephthalate PET, or tin plate. The apparatus has a cutting and pressing unit as well as means for driving and for controlling the cutting and pressing unit, wherein the cutting and pressing unit contains at least two cooperating, oppositely rotating rollers disposed at a distance relative to each other with respect to their rotation axes, wherein each roller has several disks in each case disposed towards each other with an axial distance (free space). According to a special further development it is proposed that at least in the operating region of the two rollers there are disposed axially next to each other a first working region for a compressing of containers made out of plastic and a second working region for a compressing of containers made out of metal.

1. Apparatus for the compressing of empty, deformable containers, beverage bottles or cans made out of plastic polyethylene terephthalate PET-bottles or tin plate, with a cutting and pressing unit (4) and a device for driving and for controlling the cutting and pressing unit (4),
the cutting and pressing unit (4) comprises at least two cooperating, oppositely rotating rollers (4.1 and 4.2) disposed at a distance to each other relative to their rotation axes(A1, A2), wherein each roller (4.1, 4.2) has several disks (5, 6; 50, 60, 70) disposed in each case at an axial distance to each other, wherein a first working region (21) and a second working region (22) extend axially along each of the two rollers (4.1, 4.2), wherein cutting disks (5) and pressing disks (6) of the disk in the first working region with their breadth (B1, B3) are always disposed opposite to first turned grooves (E1) of the neighboring roller (4.1, 4.2),wherein the turned grooves (E1) in the first working region (21) are always wider than disks(5, 6) in the first working region (21), wherein at least one press disk (60) in the second working region with its breadth (B4) is disposed opposite at least in part to a breadth (B4) of another press disk (60) in the second working region (22); wherein a first section (S1) is disposed at a first end of the rollers (4.1, 4.2) wherein a second section (S2) is adjoining the first section (S1) and thereby forming a first section pair, with additional first section pairs adjoining the first section pair up to a middle of the rollers (4.1, 4.2) and wherein a third section (S3) is disposed at a second end of the rollers (4.1, 4.2) and wherein a fourth section (S4) is adjoining the third section (S3) and thereby forming a second section pair, with additional second section pairs adjoining the second section pair up to the middle of the rollers (4.1, 4.2); wherein a first pressing disk with a smaller diameter is associated with the first section (S1); wherein a second cutting disk with a larger diameter is associated with the second section (S2); wherein a third press disk with a smaller diameter is associated with the third section (S3); wherein a fourth crack disk with a larger diameter is associated with the fourth section (S4); a combined disk (70) furnished at least on one of the rollers in a transition region between the first section pair and the second section pair and having a section according to the diameter of the first pressing disk and a section according to the diameter of the third press disk, wherein the combined disk having a breadth wider than the breadths of the rest of the disks of the rollers; wherein the first working region (21) has the first section (S1) with pressing disks (6) with a smaller diameter (D1) and the second section (S2) with the cutting disk (5) having a larger diameter (D2), and wherein in addition the second working region (22) has the third section (S3) with press disks (60) having a smaller diameter (D3) and the fourth section (S4) with at least one crack disk (50) with larger diameter (D4); wherein the press disks (60) with smaller diameter (D3) are broader than the crack disks (50) with the larger diameter (D4) in the second working region (22); and wherein a third turned groove (E3) is disposed radially at each roller (4.1, 4.2) between a crack disk (50) with larger diameter (D4) and a press disk (60) with smaller diameter (D3), wherein the breadth of the smaller third turned groove (E3) is smaller than the breadth of the crack disk (50) with the larger diameter (D4).
