    description
    TECHNICAL FIELD The invention relates to a cleaning device for small parts, in particular watches, with a plurality of treatment containers for the small parts, at least some treatment containers having different solvent-containing cleaning and / or rinsing liquids and into which a cleaning basket with the small parts can be immersed one after the other.
    PRIOR ART Various cleaning devices for small parts are already known, of which those used in connection with clocks are generally also referred to as clock cleaning machines.
    For example, a watch cleaning machine is known from CH 340 455, which has treatment containers arranged in a circular arc for different cleaning and rinsing liquids, into which a rotatable cleaning basket with the small parts to be cleaned is arranged one after the other, and can be pivoted about a central axis and moved up and down can immerse.
    In many cases aqueous cleaning and rinsing liquids are used for the cleaning processes of small parts, which are generally harmless in their handling with regard to an explosion risk.
    It looks different if solvent-containing media are used for cleaning and / or rinsing, because their cleaning power is usually better than that of the aqueous liquids. This can mean that these media give off volatile substances and form ignitable air-gas mixtures, which in turn represent a latent danger for the user.
    OBJECT OF THE INVENTION The object of the invention is, in particular, to avoid this disadvantage of a possible explosion hazard when using solvent-containing media in cleaning devices for small parts such as watch cleaning machines.
    Solution to the problem The embodiment according to the invention is characterized by the features of claim 1.
    Advantages of the Invention An automatic device in the form of a table-top device is preferably provided. This device is suitable for cleaning small parts automatically, preferably in different machining processes.
    The device has a processing space in which individual treatment containers are arranged, in which the small parts to be cleaned are immersed. The treatment containers are provided in an interior, which is closed to the outside, the individual treatment containers being arranged in a fixed manner in the interior. At least some of the treatment containers are filled with different liquids so that a cleaning process can be carried out.
    The material to be cleaned is received in a cleaning basket which is guided through a manipulator unit in and out of the respective treatment containers. It is also provided that the cleaning basket can perform at least one rotary movement.
    In the treatment containers, cleaning fluids are filled, which support the machining process of cleaning the small parts.
    In one of the processing containers, preferably the first in the processing process row, an ultrasonic vibrator is arranged, which supports the cleaning process.
    In addition, at least one of the processing containers can be provided with a heating or cooling device.
    Another of the processing containers provides that a blower is arranged, which is used to dry the cleaned small parts that are arranged in the basket.
    In order to avoid that a gas concentration develops in the interior, which may be flammable, a suction device is provided inside the interior. This suction device is arranged in the housing of the device, suction slots being fluidly connected to the interior with the suction device. The suction slots are preferably arranged in the upper region of the processing container, namely at the points at which they are open.
    This makes it advantageously possible to safely use flammable cleaning and / or rinsing liquids for cleaning small parts, without the risk of an explosion. In addition, the use of solvent-containing cleaning and / or rinsing liquids means that their cleaning power, which is usually better than that of purely aqueous cleaning and / or rinsing liquids, can be used.
    According to the present invention, it is expedient if a suction fan with an explosion-proof fan is used as a suction device, which has corresponding pipe connections, which make it possible for these possible ignitable gas-air mixtures from the interior, in particular above the cleaning containers can be forced into the open air, where they can then mix with the outside air and therefore no longer pose a danger due to their concentration.
    In particular when using solvent-containing cleaning and / or rinsing liquids and simultaneous ultrasound treatment, it is expedient to cool the respective processing container for the ultrasound treatment. A device is preferably provided which at least partially comprises a cylindrical processing container and, depending on the application, couples either heat or cold into the processing container and thus to heat or cool the processing liquid which is stored in the processing container.
    Finally, even with such cleaning devices for small parts, especially clocks, which are designed for purely aqueous cleaning and rinsing liquids, it is not possible to install a suction device for these, since no explosive gas mixtures can occur with purely aqueous liquids. On the other hand, the options already described for additional cleaning can provide an ultrasound treatment.
    Further details and advantages of the invention are described and explained in more detail below with reference to exemplary embodiments and the drawing.
    Drawings It shows:
    1 is a perspective view of a cleaning device according to the invention, which is shown transparently for a better explanation,
    2 is a plan view of a horizontal section through the cleaning device according to FIG. 1,
    3 shows a perspective view of a device for providing heat and / or cold, and FIG. 4 shows a side view of the cleaning device shown in FIG. 1.
    DESCRIPTION OF AN EXEMPLARY EMBODIMENT FIG. 1 shows in perspective an inventive cleaning device 1 for small parts in the form of a table-top device.
    The cleaning device comprises a housing G, which is divided into a treatment room B, in which a plurality of treatment containers 2 to 6 are preferably arranged, and in a room R for devices. This treatment room B can be closed by the user by means of a front pane F which can be opened.
    The for a better explanation in Fig. 1 and 2 quasi transparent table device has on a base 1.1 preferably at an equal distance from each other also circularly placed, cylindrical open top treatment containers 2 to 6, which consist of glass or plastic in this embodiment ,
    As can be seen from FIG. 2, on the left side of the cleaning device 1 next to the treatment tank 2 there is a device 2.1 for generating heat and / or cold, which is in the treatment tank 2 or in the liquid in the tank 2 is stored, can be coupled.
    The device 2.1, which is shown in an enlarged representation in FIG. 3, comprises a receiving shoe 2.2, which comprises the one treatment container 2 on one side. The receiving shoe 2.2, which preferably consists of a heat- or cold-conducting material, is coupled to a device 2.3 for generating the heat or cold (optionally or in combination, for example by a Peltier element).
    Depending on the embodiment, one of the treatment containers 2 to 6, preferably the first treatment container 2, can have an ultrasonic oscillator 2.4 arranged in the bottom of the treatment container 2 (FIG. 2). This ultrasonic oscillator 2.4 serves to support the cleaning effect of the small parts in the treatment container 2.
    2, the first treatment tank 2 is followed by the treatment tanks 3, 4 and 5, of which there is a cleaning liquid containing a solvent in the treatment tank 3 as well as in the treatment tank 2, whereas in the treatment tanks 4 and 5 there is a corresponding rinsing liquid is provided. It is pointed out that the division can be freely selected depending on the application. This descriptive arrangement is only an example and serves to explain the invention.
    The last treatment container 6, however, is empty and equipped with a device 6.1 for drying the cleaned small parts. For this purpose, this treatment container 6 has a grid floor 6.2, through which heated or cold air can be blown into the treatment container 6. This in turn comes from a blower 6.3, which draws in air from the outside via a suction nozzle 6.4 and, if necessary, heats it or forwards it cold to the grid floor 6.2.
    Above the treatment tanks 2 to 6 there are two intermediate floors 1.2 and 1.3 which are arranged at a parallel distance from one another and which together accommodate a mechanism 1.4 known per se, which has a sieve-like cleaning basket fastened below the intermediate floor 1.2 to a rotatable shaft 1.5 1.6 for the small parts to be cleaned. This cleaning basket 1.6 can be actuated by the mechanism 1.4 in such a way that it can execute a pivoting movement and an up and down movement in accordance with the semicircle of the treatment containers 2 to 6, in order thereby to clean the cleaning basket 1.6 one after the other after a certain dwell time in the individual treatment containers 2 to dive into 6. At a distance above the cleaning basket 1.6, coaxially to this, a cover element 1.7 is provided (FIG. 4), which closes the respective treatment containers 2 to 6 when the cleaning basket 1.6 is immersed in them. Furthermore, a suction device 7 (FIG. 2) for suctioning possible gas-air mixtures is arranged inside the cleaning device 1 according to the invention, which can form especially in the area of the treatment containers 2 to 6 when working with solvent-containing cleaning and / or rinsing liquids becomes. For this reason, the suction device 7 is designed to be explosion-proof and has flexible pipes 7.1 and 7.2 which lead outside. The suction takes place in the immediate vicinity at the edge of the processing containers 2 to 6 via suction slots 7.3 provided in a housing wall within the processing area B. The suction slots 7.3 are preferably elongated so that sufficient suction can take place over the entire edge of the respective processing container.
    The housing G of the cleaning device 1 has access to the treatment containers 2 to 6, for example, two quarter-circular folding doors made of glass or plastic. A one-piece glass front is also possible. This arrangement of the treatment containers and the doors creates the closed processing space, which is vented via the suction device 7. Furthermore, this tabletop device has on the front side an operating area inclined towards the center of the device with a control panel 1.9, with which all cleaning functions can be conveniently called up, which then run automatically.
    Finally, the cleaning device 1 described can also be designed for the use of purely aqueous cleaning and rinsing liquids, which eliminates the risk of explosion. In this case, the suction device 7 could also be omitted.
    Commercial Applicability The cleaning device 1 according to the invention, in particular in its form as a table-top device, is constructed in such a way that its individual components can be equipped with individual modules accordingly. Depending on the desired use of the cleaning device, it can thus advantageously be equipped accordingly, which then also results in price differences when viewed from the overall device.
    With a complete equipment of the cleaning device 1, this can be operated explosion-proof with solvent-containing cleaning and / or rinsing liquids by first placing the treatment containers 2 to 5 filled on the base 1.1 with its designated positions when the front pane F of the table device is open , for example, the containers 2 and 3 have been previously filled with a suitable solvent-containing cleaning liquid and the containers 4 and 5 with a solvent-containing rinsing liquid. In this case, the first treatment container 2 will be designed such that it can also be cooled or heated and / or has an ultrasonic vibrator 2.1 in the floor in order to achieve better cleaning performance.
    By pressing a button on the control panel 1.9, an automatically running cleaning program starts, namely by first lowering the cleaning basket 1.6 through the mechanism 1.4 into the first treatment container 2 until the cover element 1.7 closes it: Then a rotary movement of the sieve-like cleaning basket 1.6 executed and in the embodiment shown here, the ultrasonic vibrator 2.1 simultaneously applies ultrasound to the cleaning liquid in the treatment container 2.
    After a certain dwell time of the rotating cleaning basket 1.6 in the treatment container 2, the latter still moves upwards and is then pivoted further to the further treatment container 3, in order then to be immersed in it again until the cover element 1.7 also closes this container. Rotation of the cleaning basket 1.6 follows again, with its further movements then repeating, in the steps already described, until the cleaning basket 1.6 is in the last treatment container 6 after its previous rinsing processes, where the blower 6.3 is then started and blows warm air through the sieve-like cleaning basket 1.6 through the grid floor 6.2, for example, in order to dry the cleaned small parts. After a drying time of, for example, 5 to 10 minutes, the cleaning basket 1.6 returns to its starting position above the treatment container 2 and switches off.
    The small parts can then be removed from the cleaning basket 1.6 after opening the front of the table device.
