    The invention relates to a device for cleaning of objects, in particular of workpieces, with a rotatably mounted about a rotation axis and arranged in a working space of a housing rotation nozzle head on which a plurality of at least one pressure line for a cleaning medium connectable nozzles are arranged, wherein the working space by at least an arranged in the region of a first end face end wall and a jacket of the housing is formed, wherein a concave - preferably at least partially cylindrical - inner surface of the shell surrounds the rotary nozzle head at least partially, and the jacket of the housing has at least one outflow region for the cleaning medium, and wherein the working space is designed to be open toward a cleaning area facing away from the end wall in the region of a second end face.
    From WO 2009/094748 Al a device for cleaning containers with a rotating nozzle head is known, which has a nozzle arrangement. The nozzle head is partially surrounded by a baffle, which ensures that the main flow of the cleaning medium is directed to the center of the container to be cleaned.
    DE 20 2013 009 510 U1 describes a cleaning device and a nozzle head with at least two first nozzle rings with at least one nozzle with a tangential effective direction, between which a second nozzle ring with a radial direction of action is arranged.
    A designed as a hydraulic vortex jet working tool is known from DE 34 12 319 CI. The vortex jet nozzle has a sleeve-like rotor with nozzle inserts, from which rays exit radially. By eccentric arrangement of nozzle inserts a rotational movement of the rotor is achieved.
    Other rotary nozzles with a rotatably mounted on a stator, a plurality of nozzles having nozzle head for cleaning objects are described in publications DE 20 2010 010 979 Ul, DE 20 2005 008 470 Ul, DE 35 32 045 C2, DE 20 2006 017 974 Ul or DE 89 09 228 Ul known.
    Known cleaning devices have the disadvantage that impurities are often removed only insufficient, since the objects to be cleaned are re-contaminated with the dirt fouled. Therefore, in many cases, a post-cleaning is required.
    Austrian patent application A 50830/2014 describes a device for cleaning workpieces with a rotary nozzle head rotatably mounted in a stator and a rotation axis on which a plurality of nozzles connectable to at least one pressure line for a cleaning medium are arranged, one cylindrical concave Impact region forming side wall of the housing surrounding the arranged in a working space rotary nozzle head with a defined minimum distance. An outflow region for the cleaning medium adjoins the impact region of the housing downwards, the housing forming a cross-sectional constriction in the outflow region. The arranged below the working space outflow area allows a vertical chip removal down. However, such chip removal is not possible in any case, for example, when conveyor belts prevent discharge of the chips down. In addition, can not be ruled out in the known device that chips are whirled out of the housing and there is an uncontrolled contamination of the object to be cleaned or the equipment.
    The object of the invention is to avoid these disadvantages and to allow improved cleaning of objects.
    According to the invention this is achieved in that the jacket is at least partially surrounded by at least one channel which is connected to at least one suction line or connectable. Via the suction line in the channel suppression is generated, creating a pressure gradient between the working space and the channel. Impurities, such as chips, which are removed by the kinetic energy of the compressed air flowing from the nozzles and impinging on the object to be cleaned compressed air are sucked into the channel and thus prevented from escaping from the housing.
    The channel open to the cleaning area may comprise the jacket in an angular range of at least 180 °, preferably at least 240 °. This ensures that impurities can be trapped by the channel in any direction, whereby the kinetic energy of the impurities is sufficiently reduced to largely prevent impurities escaping from the housing. The channel thus does not cause the impurities to escape from the housing, as it does to a reduction of kinetic energy due to collision of the particles comes. On the one hand, the negative pressure forming in the channel increases the braking effect of the impurities flowing around and, on the other hand, supports the removal of the impurities from the working space in which the actual cleaning of the object takes place.
    Preferably, a discharge chamber connected to the suction line is arranged in the outflow region, which is flow-connected to at least one end of the channel, preferably to a first and a second end of the channel. The outflow chamber, which is designed to be sealed off from the second end side, preferably by a removable cover, can be connected to the working space via at least one opening in the jacket. This can be sucked both from the surrounding channel, as well as from the working space. The outflow chamber acts as a collecting space. The connection of the suction line to the outflow chamber can take place in any direction, for example horizontally, so that the space under the housing can also be used for other system components, for example a conveyor belt.
    Particularly good results could be achieved if the extracted from the working space and the channel and entering the outflow chamber air mass flow is divided in the ratio 40:60. The opening in the shell between the working space and the outflow chamber, as well as the cross-sectional areas of the shell in the region of the first and second end are designed accordingly.
    In the context of the invention it is provided that the channel in the region of the first end opens substantially horizontally and in the region of the second end substantially vertically into the outflow chamber. It is particularly advantageous if the channel between the first and the second end has a cross-section which extends preferably continuously. The channel is structurally advantageously designed so that it forms a continuously harmoniously expanding cross-sectional profile between the first and the second end.
    Recombination of the object to be cleaned and contamination of equipment surrounding the device can be effectively avoided if the extracted mass flow is about two to six times, preferably four to five times the introduced via the nozzle mass flow of the cleaning medium - preferably air -.
    The invention will be explained in more detail below with reference to the non-limiting FIG.
    Show it
    1 shows an inventive device for cleaning objects in an oblique view,
    2 shows this device in a side view,
    Fig. 3 shows the detail III of Fig. 2 and
    Fig. 4 shows an arrangement of two devices according to the invention.
    The figures show a device 1 for cleaning - not shown - objects, such as workpieces or machine parts. The device 1 has a housing 2 with an end wall 4 arranged in the region of a first end face 3 and a substantially cylindrical jacket 5, wherein the end wall 4 and the inner lateral surface 5a of the jacket 5 span a working space 6, in which one about an axis of rotation 7a rotatably mounted in the housing 2 rotary nozzle head 7 is arranged. The axis 7a is arranged substantially normal to the end wall 4. The rotary nozzle head 7 has at the end of radially arranged rotary arms 8 nozzles 9, which arranged in or on the rotary arms 8 and the hub 10 of the rotary nozzle head 7 - not shown - fluid connections with a pressure line not shown for supplying a pressurized cleaning medium , For example, air are connected. The nozzles 9 can be formed pivotable about an angle between about 0 ° and 30 ° about the longitudinal axes 8a of the rotary arms 8, whereby the rotational speed of the rotary nozzle head 7 can be adjusted. The drive as well as the speed adjustment of the rotary nozzle head 5 thus takes place via the employment of the nozzles. 9
    The concave cylindrical inner circumferential surface 5a surrounds the rotary nozzle head 5 with a minimum distance to the rotary arms 8 and the nozzles 9. The nozzles 9 may possibly be divided into drive nozzles and cleaning nozzles. The jacket 5 is interrupted at least in an outflow region 11, so that the working space 6 and via at least one opening 12 in the jacket 5 is connected to an adjoining outflow chamber 13. The outflow chamber 13 is connected via a suction line 14 with a mammal pump, not shown. The working space 6 is designed to be open in the region of a second end face 15 facing away from the first end face 3, in order to enable a cleaning of the object to be cleaned. The open side of the working space 6 forms the cleaning area 16 for the object.
    The jacket 5 is surrounded by an at least predominantly substantially annular channel 17, which in the exemplary embodiment comprises the jacket 5 in an angular range α of approximately 270 °. The angle range α is - viewed in a section transverse to the axis of rotation 7a - defined by the axis of rotation 7a extending outermost radial line nlr n2, which are normal to the inner circumferential surface 5a of the jacket 5 (see Fig. 2) is also open to the second end face 15 and is formed by the radially elongated end wall 4, an outer lateral surface 5 b of the shell 5 and a peripheral outer housing wall 18. The channel 17 opens with its first end 17a and its second end 17b in the outflow chamber 13 on both sides of the opening 12 a.
    The outflow chamber 13 is designed to be closed to the second end face 15 and covered, for example, by a removable cover 19.
    In the illustrated embodiment, the channel 17 opens substantially horizontally in the region of the first end 17a and substantially vertically in the outflow chamber 13 in the region of the second end 17b and has a continuously widening cross section between the first end 17a and the second end 17b. As can be seen in FIGS. 1 and 2, the two ends 17a, 17b may be formed by substantially straight channel portions which tangentially connect to an annular channel portion 17c of the channel 17.
    The on the one hand from the working chamber 6 and on the other hand sucked out of the channel 17 and entering the outflow chamber 13 air mass flows are divided in the ratio 40:60. The total mass flow extracted via the suction line 14 is, for example, approximately two to six times the mass flow of the cleaning medium introduced via the nozzles 9.
    The nozzles 9 are arranged substantially in a normal plane on the rotation axis 7a. The housing 2 is formed for example by sheet metal. The end wall 4 is formed at least in the region of the rotary nozzle head 5 substantially normal to the rotation axis 7a. The inner lateral surface 5a forms a substantially cylindrical concave impact region. The radius of the inner lateral surface 5a results from the radius of the rotary nozzle head 7, as well as a safety allowance of, for example, 5 mm.
    The length of the rotary arms 8 can be optimized depending on the size of the object to be cleaned and the available cycle time. In general, long rotating arms 8 are advantageous, for example, for large-sized objects to be cleaned.
    Experiments have shown that up to four rotating arms 8 and nozzles 9 mounted thereon can advantageously be provided, wherein the length of the individual rotating arms 8 can also be different in order to achieve the best possible cleaning effect. For example, it is possible to provide a first group of two nozzles 9 each having short rotation arms 8 and a second group of two nozzles 9 each having long rotation arms 8, wherein in each case equally long rotation arms 8 can be arranged diametrically relative to the rotation axis 7a in order to avoid imbalance ,
    Fig. 4 shows an arrangement with two devices 1 for cleaning an object. The two essentially mirror-inverted devices 1 are arranged with their open second end faces 15 facing away from each other so arranged that the object to be cleaned between them can be positioned. Thus, two mutually averted sides of the article can be cleaned simultaneously.
    The cleaning of the article takes place in that the cleaning medium, such as air, applied at relatively high pressure and high speed through the nozzles 9 on the surface of the article and thus impurities such as chips or the like, are rinsed. To avoid contamination of other parts of the system, the distances between the object to be cleaned and the devices 1 should be as small as possible. Due to the high pressure and the high speed of the cleaning medium, the detached impurities have in part a high kinetic energy. The impurities are sucked in each device 1 by the prevailing in the outflow chamber 13 in each case suppression in the annular channel 17. The circumferential channel 17 causes by its shape and the prevailing suppression that the kinetic energy of the impurities, for example, by colliding with the walls of the channel 17 and by slowing down the circulating dirt particles, largely degraded. A re-emergence of the contaminants from the channel 17 can thus be effectively prevented. In addition, the removal of impurities from the working space 6 is supported by the suppression in the outflow chamber 13. For example, the horizontal removal of impurities makes it possible to keep the space below the housing 2 largely free of contamination and thus to use for the arrangement of other system components, such as a conveyor belt.
