Definitions

  • This invention relates to a device for washing a conveyor chain and its elements for gripping containers, for example plastic bottles, after said chain and elements have been dirtied with paint or other products used to coat the containers at a coating station.
  • the coating plants can be of very different sizes, also depending on the productive capacity of the plant that can vary from hundreds to several thousands of bottles per hour.
  • these plants are highly automated; they comprise a station for loading the containers to be painted, a coating station, and a paint reticulation station (for example, equipped with furnaces suitable for the type of paint used in the process).
  • containers are moved from one station to another by means of conveyor chains equipped with gripping devices or on conveyor belts.
  • the coating plants also include a washing station or a station for cleaning the gripping devices, such as chucks or grippers, and the conveyor chain that get dirty during coating.
  • Coating can be of two types: spray coating with spray nozzles, or immersion in dipping tanks full of paint.
  • a problem that generally arises with these plants is the difficulty in removing paint residues from the chain and from the bottle-gripping devices, especially after the paint or the coating has dried or has started to reticulate or, worse still, after drying in furnaces when required by the chosen coating process.
  • dried paint residues on the gripping devices and on the chain - which usually involve moving parts - negatively affect the performance of said devices and increase wear, which increases running costs besides increasing downtime due to maintenance work.
  • the inside of the bottle is contaminated: for example, when a gripping device of the chain does not grab a bottle; consequently, the parts of the gripping device that normally are in contact with the inside of the neck of the bottle, which should never be dirty of paint, are also coated, contaminating subsequently gripped bottles.
  • the internally contaminated bottle or container must be carefully inspected and rejected since the paint is not fit to come into contact with the drink or foodstuff to be packaged in the container.
  • One of the solutions recommended in the past to overcome these problems is to include washing or cleaning stations along the circuit of the conveyor chain.
  • a device for washing conveying and/or gripping devices of containers operating along a specific travel path comprising at least one pre-washing area, washing area, and rinsing area.
  • Said washing area comprises a tank suitable to contain a washing liquid into which said conveying and/or gripping devices are immersed during a washing operation carried out in a specific segment of said travel path; the tank also comprises ultrasound generators positioned on the walls and on the bottom, suitable to be operated during said washing operation.
  • a method for washing the conveying and/or gripping elements of containers, especially plastic bottles implemented by means of the washing device as claimed in one of the previous claims, comprising the steps of: a) feeding said conveying and/or gripping devices of containers into said washing device from the pre-washing area b) spraying said conveying and/or gripping devices with a pre-washing detergent liquid in said pre-washing area c) feeding said conveying and/or gripping devices into the washing tank containing a washing liquid, immersing them up to a predetermined level d) emitting ultrasounds of predetermined intensity by ultrasound generators positioned on the walls and on the bottom of said washing tank e) at the end of a predetermined amount of time, feeding said conveying and/or gripping devices into a rinsing area where they are rinsed with a rinsing liquid Thanks to the innovative characteristics of the washing device in accordance with the invention, the device is suitable for washing chains and gripping devices - such
  • the washing station can be placed in different points of the coating plant: directly after the coating station, in which case the containers are removed just after said coating station and sent to another processing circuit; or after the forced-drying or air-drying area in the case of a single conveying circuit.
  • the conveyor chains are divided into two separate circuits, the so-called wet and dry circuits, and the circuit that goes through the coating stations, meaning the wet circuit, does not go through the drying furnace.
  • This option has the added advantage of facilitating and making more economical the cleaning operation of the container-gripping devices dirtied during each cycle, since the paint does not have the time to reticulate.
  • the presence of an in-line washing station whether it is placed in a wet area separate from the dry area or after the dry area, leads to less machine downtime for maintenance work or for replacing the gripping devices that are too soiled or worn out.
  • FIG. 1 shows a longitudinal section of the first version of a washing device in accordance with the invention
  • FIG. 2 shows a cross section of the washing device of Fig. 1
  • Fig. 3 shows a plan view with partial sections of the washing device of Fig. 1 Detailed description of the invention
  • the aforementioned figures show a washing device, hereinafter also referred to as reference 1, comprising a central washing area (2) and a tank (7) containing an appropriate detergent liquid - normally a solvent suitable to dissolve the type of paint or product used in the coating process - during operation. Furthermore, the device includes a pre-washing area (3) positioned before the washing area (2), and a rinsing area (4) positioned after the washing area (2).
  • the conveyor chain (5) is equipped with the container-gripping elements, the so-called chucks (6) or other similar gripping devices, and travels along the predetermined path before going through the pre-washing area (3), then through the washing area (2), and, finally, through the rinsing area (4).
  • the washing area (2) features a system for generating ultrasounds that are directed at the fed-through chain segment and at the gripping devices. Defining appropriately the ultrasound generating parameters, also depending on the type of paint used in the coating process and the solved found in the washing tank (7), results in optimal washing of the components that pass through the device (1 ). As a function of these parameters, it is possible to define the operating frequency of the washing device, which can be used at every passage of the chain or at specific time intervals definable through testing.
  • the ultrasound generating system amplifies the cleansing power of the liquid; it requires ultrasound generators (14, 15) to be positioned at the bottom and on the sides of the washing tank (7).
  • the cleansing action is more effective if the sides of the tank (7) are placed at an angle in relation to the vertical direction, so that they get nearer in the bottom area.
  • the external walls of the washing device (1 ) can be appropriately soundproofed in order to reduce environmental noise levels.
  • the pre-washing area (3) preferably in the form of a channel that leads into the washing tank (7), features a spray-pre-washing device.
  • the rinsing area (4) is also equipped with spray nozzles (9) that spray the solvent onto the chain to eliminate any residues left on the chain (5) and on the chucks (6).
  • This area can also feature spray tunnels or similar devices.
  • the pre-washing, washing, and rinsing operations are carried out with the same solvent liquid.
  • the washing tank (7) is placed at a level lower than the pre-washing (3) and rinsing (4) areas.
  • the conveyor chain is a two-planar chain that bends on two planes that are orthogonal to each other.
  • Some ducts (8 and 8') for supplying the spray nozzles of the pre-washing and washing areas are required in all areas of the washing device (1 ); the ducts are supplied by pumps (11) from a container (10) filled with washing liquid. The container (10) is also fed by overflow ducts (not shown in the figures) that dump any excess washing liquid from the washing tank (7). Appropriate filters (12) are required in the delivery ducts.
  • the container (10) can feature known heaters for heating the detergent liquid.
  • a drying device (13) equipped with compressed-air and/or hot-air jets or room- temperature fans can be placed after the rinsing area (4).
  • Height-adjustable mechanisms (not shown in the figures) for lifting from the floor the part of the device (1) comprising the pre-washing, washing, and rinsing areas allow the device to be adjusted to the different heights of the conveyor chain, making it possible to choose how much of the chain and chucks are immersed into the liquid during washing or whether to use the entire washing device on the chain. In this case, the lifting mechanism can lower the entire device outside the immersion area of the chain.
  • washing device (1) to wash the chain is carried out as specified below.
  • the washing device (1 ) is lifted to the height of the feeding line of the chain in order to immerse the gripping devices into the liquid contained in the tank (7) up to a certain level.
  • the chain (5) and the chucks (6) are sprayed in the pre-washing station (3) with an appropriate detergent liquid suitable to prewash. Then, the chain is fed into the washing tank (7) that is filled up to a predetermined level with detergent liquid suitable for washing, and is fitted with ultrasound generators of determined intensity. After a predetermined amount of immersing time, dependent on the type and condition of the paint that contaminates the chain and gripping devices, that can be adjusted by defining the feed rate of the conveyor chain and/or by defining the length of the different areas of the device (1), the chain emerges from the washing tank (7).
