Definitions

  • Essential parameters for washing lines are the quality of washing and the smoothness of operation. To a great extent, both depend on the washing line settings and are also largely affected by the dimensions and parameters of the line.
  • the shaping of the wash zone of the line is important when washing crates or boxes of various shapes and sizes.
  • the standard washing process takes place so that the crate is transported upside down by the input conveyor to the washer.
  • the crate is caught by pins of the guide chains or washer conveyor from the inside.
  • the washer chain pins ensure that the crate does not fold when passing through the washer, even if it is not locked in the locks.
  • the crate When passing through the washer, the crate is sprayed with water distributed using pumps and a nozzle system.
  • the frame inside the washer in which several sets of nozzles are installed in a row, one above the other or next to each other and mostly with added detergent/disinfection, is divided into Pre-wash, Main wash, Disinfect rinse and Clean water rinse sections. These nozzle sections are permanently installed in the washer, wherein the nozzle system acts on the crate or a given place on the crate by pressure from different sides and angles with 3, 6, or up to 20 bar from above, from below and from both sides along the washer guide.
  • the crate can be washed without being lifted, overturned, folded or rotated in the washer.
  • the nozzles on one or both sides are more or less distant from the crate, i.e. act on the crate or the given place on the crate with different pressures.
  • the crate is taken out of the washer to the output conveyor.
  • the length of the standard washer used for this calculation is 18.6 m
  • Labels are glued to the shorter side of the crates. It is, therefore, necessary to expose this side to the most efficient and effective washing.
  • Document WO 2005028130 A1 discloses a washing module, also for washing beverage crates, comprising horizontal brushes, vertical brushes and a mechanism for lifting crates, wherein the outer brushes, according to Figures 12, 13 and 14 , do not rotate around their axes but are located on a rotating mechanism allowing the brushes to move around crates.
  • This module washes all four crate sides in one go because it aims to wash the crates perfectly from dirt, not to remove the labels and stickers.
  • Document JP 2001232308 A discloses a washing module for crates that are washed with nozzles from all possible sides.
  • the washing module does not have brushes.
  • Document CN 208261460 U discloses a washing module for buckets and other round containers.
  • the buckets are fixed on a conveyor; preferably, the buckets rotate around their axes and are washed by passing through the brush section.
  • the brushes are static.
  • Document CN 208357415 U discloses a washing module for crates, which is not intended for high-pressure and high-speed washing, as the module must first be opened on one side by lifting the horizontal brush. Then, each crate must drive into the module, the module closes, the crate is washed, the module opens again, and the crate leaves.
  • This batch washing method is highly inefficient, both in time and money.
  • the pressurized water is pumped continuously, leading to massive waste or is switched on and off with opening and closing of the module, which brings pressure shocks to the system, and the system wears out very quickly.
  • Document DE 20021637 U1 discloses the washing module for crates when the crate is placed on the conveyor with the bottom backwards or forwards, i.e., placed on its side. In this way, it passes through a carwash-like brush section, i.e. two vertical brushes on both sides of the conveyor and one horizontal brush above the conveyor. Another brush can be placed under the conveyor. Thanks to this, the crate is washed from three or four sides in one go, only from the outside. Again, the goal is to clean the crate from dirt on all sides at one time, not to remove labels and stickers.
  • a carwash-like brush section i.e. two vertical brushes on both sides of the conveyor and one horizontal brush above the conveyor. Another brush can be placed under the conveyor. Thanks to this, the crate is washed from three or four sides in one go, only from the outside. Again, the goal is to clean the crate from dirt on all sides at one time, not to remove labels and stickers.
  • Document US 1883772 A discloses, similarly to document D6, the washing of crates sitting on their side.
  • the washing module for such washing also includes a tilting mechanism.
  • the crate lying with its bottom on the conveyor is rotated by 90 degrees to be placed with its side down on another conveyor. In this position, it is washed by passing through a brush section analogous to that in DE 20021637 U1 , i.e., two vertical brushes on the sides of the conveyor, one horizontal brush above the conveyor and another horizontal brush below the conveyor.
  • the brush section of the tunnel washing lines for removing labels from the crates is equipped with a conveyor for passing the crate through the brush section, a rinsing with water, at least one left side brush situated on the left side of the brush section wash zone and at least one right side brush situated on the right side of the brush section wash zone, wherein both the left side brush and the right side brush are of circular cross-section, and through the centre of the left side brush the left side line a passes, which is parallel to the right side line b passing through the centre of the right side brush, the left side line a and the right side line b being parallel to the h axis of the conveyor feed, and the distance o between the left side line a and the right side line b is ps + 1 ⁇ 2r a , + 1 ⁇ 2r b ⁇ o ⁇ p s + r a + r b , where ps is the width of the crate, r a is the radius of the left side brush, rb is

Lifting fixators are only used to grip the crate and lift it. To return the crate to the bottom part of the wash zone, reversible means are then used, which actively push the crate downwards.
  • the reversible forks are located above at least two side plates of the crate placed bottom down on the lifting mechanism in the brush section. The reversible last is located above the bottom of the crate placed bottom down on the lifting mechanism in the brush section.
  • the lifting plate is used to lift the crate upwards.

  • the position of the brushes in the brush section 1 is shown in Figures 24 and 25 .
  • the crate 3 with a label comes from the customer.
  • the customer's requirement is that after washing, only the bottom layer of the sticker can remain on the crate, i.e., essentially only a 2x2 cm glue. This is an acceptable result of washing, in which case after washing, the crate with such 'residue' is further operated as clean.
  • the crate 3 travels to the classic high-pressure industrial tunnel washing line for washing. After washing, a large amount of paper sticker remained on the crate, see Figure 33 , more than the acceptable amount of 2x2 cm glue. In such a case, the crate 3 is excluded from the conventional washing process and travels to be 're-washed' to the desired state into the brush section 1 , which guarantees the removal of the remnants of the sticker from the crate 3.
  • the soiled crate 3 was taken bottom down by the conveyor to the brush section 1 according to Example 4, where it was gripped by the lifting fixators 9 and lifted into brushes rotating around their axes at a speed of 800 revolutions per minute.
  • the crate was secured with four reversible forks located in the place of the side plates of the crate, one fork for each side plate. After 1 s in the upper position, i.e., in contact with the brushes, the crate 3 was pushed out of the brushes by the reversible forks, back onto the conveyor 2 and the lifting fixators 9 moved away from the crate.
  • the crate 3 was lifted into the brushes only once; in cases of extreme soiling the crate 3 can be lifted into the brushes several times, or the speed of rotation of the brushes can be increased or direction of their rotation can be changed. At the same time, it is possible to extend the contact of the crate 3 with the brushes or increase the speed of lifting the crate 3 into the brushes and returning the crate 3 onto the conveyor 2. After releasing the lifting fixators, the crate was collected again by the conveyor 2 and taken out of the brush section 1 . The time the crate 3 passed through the brush section 1 was 2 s. After passing through the brush section 1 , the crate 3 was thoroughly washed, see Figure 35 .
