Definitions

  • the present invention relates to a device for cleaning workpieces.
  • the device has at least two cleaning chambers, wherein the cleaning chambers have formed a receptacle for a workpiece.
  • Each of the cleaning chambers is designed such that a cover can be placed on the respective cleaning chamber.
  • the invention relates to a method for cleaning workpieces, wherein the method uses at least two cleaning chambers.
  • the German patent DE 195 44 074 C2 discloses an automatic cleaning system for workpieces.
  • the cleaning system is used to remove machining residues from workpieces.
  • the cleaning station has a channel for receiving at least one workpiece to be cleaned.
  • a workpiece transport device is provided for introducing the workpieces to be cleaned into the channel and for removing the cleaned workpieces from the channel.
  • Inside the duct at least one cleaning nozzle is aimed at the workpieces.
  • the cleaning nozzle is used as a blowing nozzle for acting on the workpiece with a blown air jet, which is preceded by an air conveyor for supplying air to the tuyere.
  • the proposed in the patent cleaning system is not sufficient to meet the increased demands on the cleaning of the workpieces.
  • the German utility model DE 296 20 946 U1 discloses a parts cleaning machine.
  • the machine proposed in the utility model works as a combined spray-dip machine and can be operated with one or two basket inserts (also alternately).
  • the basket insert is designed as a flat basket insert and the other basket insert is a rotating basket. Regardless of whether one or two baskets are used, the respective basket insert can be used in spraying and / or immersion operation, wherein in the latter case the flat basket as well as the rotary basket in a dip tank is retractable.
  • the flat basket is over a platform or a cart is introduced while the rotary basket is fed by hand.
  • This part cleaning machine proposed here also does not meet the requirements to achieve a certain quality of cleaning.
  • the invention has for its object to provide an automatic device for cleaning workpieces that meets high cleanliness requirement in terms of cleaning of the workpieces.
  • the device for cleaning workpieces is equipped with at least two cleaning chambers.
  • the cleaning chambers have a receptacle for a workpiece to be cleaned, wherein each of the cleaning chambers is designed such that they can be closed with a lid.
  • the cleaning chambers are provided on a rotating device and arranged such that each of the cleaning chambers is associated with a lid, wherein the lids are arranged stationary. Further, each of the lids is provided with a supply for a medium. Since the cleaning chambers are rotatably mounted on the rotating means, they can be positioned relative to the respective lid. Before one of the chambers changes to the next lid position, the entire lids are lifted by the cleaning chambers and the rotator rotates the cleaning chambers to the next desired position where a lid is located.
  • the device according to the invention thus eliminates the need to place heavy masses on the turntable. Furthermore, no distribution systems for the supply of the media are necessary. This minimizes the carryover of media to a minimum.
  • Another advantage of the device according to the invention is that in the vacuum drying, which is performed in at least one chamber, it can not come to media residues, since the liquid acted upon cleaning chambers no longer get to the station or cleaning chamber of vacuum drying. It is obvious to a person skilled in the art that other drying methods besides vacuum drying can be carried out. Other drying methods are hot air drying and / or cold air drying.
  • one of the cleaning chambers forms an up / down station for the workpieces. If the cleaning chamber is in the position for loading / unloading the workpiece, this cleaning chamber need not be assigned a lid.
  • the rotating device for the cleaning chambers is designed as a rotary table. On the rotary table, the individual cleaning chambers are arranged in a symmetrical manner.
  • the cover for the cleaning chambers is provided with a feed for the respective medium required for the respective cleaning step. Furthermore, the cleaning chamber is provided with a drain for the media used. It is particularly advantageous if at least two but at most eight cleaning chambers are arranged on the rotary table. It is particularly advantageous if at most six cleaning chambers are arranged on the rotating device.
  • the method according to the invention is characterized in that at least one workpiece is deposited in one of the at least two cleaning chambers.
  • the cleaning chambers are closed for the cleaning of the workpiece with a lid, wherein over the lid a respectively required for a running in the cleaning chamber cleaning step medium is supplied.
  • the lid is lifted off the at least two cleaning chambers and the cleaning chambers are transported to the next position, opposite which a stationary lid is provided.
  • the lid is lowered onto the cleaning chambers for the other cleaning step.
  • the medium is then supplied via the lid.
  • the cleaning chambers are, as already mentioned, transported from one position to the next. In this case, a different cleaning step can be performed at each of the new positions.
  • the new cleaning step is always carried out when the cleaning chambers are in the respective intended position and the lid has been lowered onto the cleaning chambers. According to the previously configured cleaning process can then be supplied via the lid, the corresponding medium for the cleaning step. It is also possible for more than one cleaning chamber to carry out the same cleaning step for increasing the throughput of the workpieces to be cleaned.
  • the rotating device is provided with at least one chamber in which a vacuum drying takes place.
  • the cleaning chambers provided on the rotating device the workpieces with high cleanliness requirements of emulsions, oils, fats and chips and particles from turning, milling, sawing, drilling, tapping and / or grinding are subjected to the various cleaning steps.
  • FIG. 1 shows a perspective view of the arranged on the rotator cleaning chambers.
  • FIG. 2 also shows a perspective view of the arranged on the rotator cleaning chambers, wherein the lid, which close the cleaning chambers for the cleaning step, are lifted.
  • FIG. 3 shows a plan view of a cleaning chamber, as it is arranged on the rotator.
  • FIG. 4 shows a side view of the arranged on the rotating device chamber, wherein the lifted off the chamber lid is shown in dashed lines.
  • FIG. 5 shows a plan view of the lid, with which the cleaning chambers can be closed.
  • FIG. 6 shows a side view of the lid, with which the cleaning chambers can be closed.
  • FIG. 7 shows a bottom view of the lid, which is provided with a medium distribution device.
  • a cleaning system for workpieces comprises additional additional components, such as, for example, B. the plant housing, a transfer and removal device for the workpieces and a corresponding control device which controls the cleaning process of the individual workpieces.
  • B. the plant housing a transfer and removal device for the workpieces
  • a corresponding control device which controls the cleaning process of the individual workpieces.
  • the user of the cleaning system can configure the cleaning processes for individual workpieces.
  • the different workpieces make different demands on the cleaning process. This can be, inter alia, in the cleaning time required for the respective workpiece or in the cleaning medium required for the workpiece.
  • the same reference numerals are used in the various figures to illustrate the invention.
  • FIG. 1 shows a perspective view of the device 1 for cleaning workpieces (not shown).
  • the device 1 comprises a plurality of cleaning chambers 2, which are arranged on a support 4.
  • the carrier 4 is designed as a rotating device which is rotatable about an axis 6. The rotation about the axis 6 can only be performed when the lid 8, which close each of the cleaning chambers 2 have been lifted from this.
  • the lid 8 is not shown, so as to describe the interior of the cleaning chamber 2.
  • the cleaning chamber 2 has at least one receptacle 10 for a workpiece.
