Definitions

  • the invention relates to a discharge device for media, in which manual operation, e.g. one or more discharge conveyors are actuated by finger pressure on opposite printing surfaces in such a way that a certain amount of medium is discharged from one or more media stores or the respective discharge conveyor through an outlet channel to one or more discharge openings and through these to the outside.
  • manual operation e.g. one or more discharge conveyors are actuated by finger pressure on opposite printing surfaces in such a way that a certain amount of medium is discharged from one or more media stores or the respective discharge conveyor through an outlet channel to one or more discharge openings and through these to the outside.
  • the media storage is expediently partially or essentially completely enclosed within at least one of the operating units.
  • the design can be such that at least the associated actuation unit must be opened for this purpose or detached from the other actuation unit.
  • the actuation units can only be assembled after the media store or media has been inserted. Regardless of whether the media storage is already used in the manufacture of the discharge device or only by the user, this type of assembly can be cumbersome, time-consuming and prone to errors.
  • the invention is furthermore based on the object of providing a discharge device of the type mentioned, in which disadvantages of known designs or of the type described are avoided and which in particular ensures very simple assembly of the media store.
  • the discharge actuation forms a preassembled, one-piece or formed by separate components with both areas to be moved against each other via the actuation stroke, which can be completed or assembled as an assembly or assembly before the media storage is used.
  • this assembly assembly has an externally accessible holder, into which the media store can be inserted at any time so that it is then in a functional position, e.g. already connected to the discharge conveyor or the outlet channel or by a switching movement into it Connection position can be transferred.
  • This makes the Training according to the invention is also particularly good for automated production, because the discharge device can be completely prefabricated except for the arrangement of the media store and then the previously filled media store can be inserted and secured in a single assembly movement and without separate fastening parts.
  • the media store expediently forms part of the discharge conveyor itself, namely in addition to its storage function e.g. an elastic, but preferably a dimensionally stable pressure or pump chamber, the chamber volume of which is reduced by the actuation.
  • the stored medium can then be squeezed out in dosed quantities either in a single actuation stroke at once or by stroke-limited partial strokes.
  • the assembly of the discharge actuation expediently forms a substantially closed, for example approximately cylindrical, housing on the circumference and / or on one or both end faces, which has the discharge opening on one end or one side and an insertion opening on another side, particularly the side remote therefrom for the media store, which has a cross-section which is substantially smaller than the surface extent of this side, so that the boundaries of the insertion opening and / or an end section of the media store lying in the region of the insertion opening can form an actuating handle or pressure surface.
  • the insertion opening can be partially or completely closed by the media store used without additional means.
  • the media storage device can be opened at a front end in the insertion direction during insertion to a width which essentially corresponds to its remaining inner width.
  • the filled media store is then closed at the open end when inserted into the assembly by an engagement member provided on the assembly, which forms a pump piston or an additional guide or centering of the actuating units and the media store against each other.
  • the actuation units are secured to one another by at least one additional guide.
  • a guide can be formed by overlapping cap sleeves of the actuating units or through overlapping sleeves that are spaced within the outer shell of the assembly, these additional guides spacing the engagement member or the media storage on the outer circumference.
  • the two actuation units are expediently also secured positively against pulling apart from one another by stops, these stops being able to form a snap connection which automatically engages when the two actuation units are assembled.
  • the media storage is expediently also fastened by an approximately linear plug-in movement which can be approximately rectified or parallel to the plug-in movement with which the actuating units are assembled.
  • a further snap connection separate from the snap connection between the actuation units and / or axially spaced therefrom is advantageously provided, which directly fixes the media container only in relation to one of the two actuation units, expediently without play both in and against the direction of insertion.
  • This snap connection can also be made by inserting the media container accordingly Snap resilient training by itself.
  • inclined insertion surfaces can be provided for the latching members and / or the storage area, which are expediently attached essentially only in the edge region of the insertion opening, so that the media storage area on the outer circumference can have constant cross sections essentially over its entire length.
  • the corresponding snap connection can also form an anti-rotation device for the media store.
  • the media store When inserting, the media store can be held particularly securely if it has a gripper member at its rear end, on which it is attached with a e.g. mandrel-shaped gripper can be precisely aligned and taken up essentially without play.
  • This gripper member which can be formed by an extension of the sleeve jacket of the media store which projects freely over a base wall, is expediently formed in one piece with the rest of the media store and has stops or snap members of the snap connection.
  • the remaining longitudinal section of the media store can be supported on the outer circumference, if necessary, with radial prestress relative to the associated actuating unit, so that the media store is secured against deformations under the discharge pressures occurring even in the case of a relatively thin-walled design.
  • the discharge device 1 has a compressible discharge actuation 2 for a discharge conveyor 3 lying completely in it with two essentially dimensionally stable actuation units 4, 5, which form a closed housing 6.
  • each actuating unit 4 or 5 forms a cap 7 or 8, and the caps are put together.
  • the discharge conveyor 3 lying completely inside the housing 6 can have one or more pumps, media stores 10, pump pistons 11, outlet channels 13 and / or discharge openings 14, for example, in such a way that a pump piston 11 can be inserted one after the other into a series of media stores 10, which according to Art a turret arrangement are arranged in a ring.
  • the parts mentioned are only provided in a simple manner and lie essentially in a common axis and essentially completely within the housing 6.
  • a discharge nozzle lying approximately in the central axis mentioned 16 to the outside, which has the discharge opening 14 in the region of its free end and can be covered with this by a removable closure cap 17, which can be preassembled independently of the media store 10.
  • a holder 20 is provided which protrudes substantially freely from the end wall 21 of the cap 7 in the housing 6 and with its free end approximately to the level of open end face of the cap shell 18 can range.
  • the outside of the end wall 21 forms an actuator 22 of the discharge actuator 2, and the holder 20 does not protrude beyond the pressure surface forming this actuator 22, but is essentially flush with it.
  • the other actuator 23 is formed by the end face of the end wall 15 facing away therefrom and arranged in a ring around the discharge nozzle 16.
  • the bracket 20 is by a the insertion wall 24 penetrating the end wall 21, the boundary of which lies at a radial distance within the outer or inner circumference of the casing of the housing 6 and which is formed by the associated end of a mounting shaft 25.
  • the support shaft 25 is formed by the inner circumference of a sleeve 26 which is formed in one piece with the end wall 21 and projects freely inward from the latter, which sleeve is closely matched to the outer circumference of the media store 10 and receives it essentially over its entire length.
  • a snap connection 27 is provided between the media store 10 and the sleeve 26, which engages when the media store 10 is inserted through the insertion opening 24 and has reached its mounting position.
  • the jacket of the sleeve 26 forms in connection to the end wall 21 at two or more locations distributed over the circumference radially outwardly projecting projections 28 which on their inner sides are opposed longitudinal grooves 29 for the displaceable reception of snap cams 30, which over protrude the outer circumference of the media store 10 at most by the wall thickness of the sleeve 26 and are formed in one piece with the media store 10.
  • the grooves 29 have, following the outer end face of the end wall 21, insertion bevels which are assigned correspondingly inclined end faces at the front ends of the snap cams 30.
  • the inner ends of the grooves 29 are essentially closed by corresponding inclined surfaces, but can be resiliently pressed apart by the inclined end surfaces of the snap cams 30 so that the snap cams 30 drive over them and then can engage behind the inner end surfaces of the projections 28.
  • Each snap cam 30 is then in the associated end of a longitudinal slot 31 of the jacket of the sleeve 26, this slot 31 can go through to the free end of the sleeve 26.
  • the slot 31 adjoins the respective end face of the projection 28, in the area of which the sleeve 26 is closed over the circumference and which forms an anti-rotation device for the media store 10.
  • the insertion movement of the media store 10 is limited by two stops 32 which are offset in the circumferential direction relative to the snap cams 30 and which also protrude in one piece over the outer circumference of the media store 10, which engage in pockets 33 on the inner circumference of the sleeve 26 or the insertion opening 24 and likewise one Form anti-rotation device.
  • the stops 32 abut the bottom surfaces of the pockets 33 at the moment when the snap cams 30 come into a locked position, so that the media store 10 is then secured in a form-fitting and non-detachable manner in both opposite directions.
  • a releasable connection to the actuating unit 4 is also conceivable for the interchangeable arrangement of the media store 10.
  • the snap cams 30 lie axially immediately adjacent to a bottom wall 34 which is in one piece with the storage device, namely on an extension 35 of the casing 37 of the media storage device 10 protruding from the outside thereof Picking up the media storage 10 with a suitable gripper and in the installed position lies completely within the insertion opening 34. At the end of this extension 35, the stops 32 are also provided. Due to the position described, the snap cams 30 are securely supported against relative movements relative to the jacket 37.
  • the inner circumference of the media store 10 forms approximately from the bottom wall 34 to the open, slightly funnel-like Widened end of a cylinder track 12 for the pump piston 11, which is attached to the end of a plunger projecting freely beyond the inside of the end wall 15 and formed in one piece with the actuating unit 5 by inserting a piston shaft.
  • the pump piston 11 projects beyond the open end face of the cap jacket 19.
  • the two actuation units 4, 5 are already secured to one another against axial pulling apart and twisting by at least one snap connection 39 and at least one guide 42, 43.
  • a guide 42 is formed by the two interlocking cap sleeves 18, 19. From the end wall 15 of the cap 8, a further sleeve 38, which is spaced within the cap jacket 19, projects inward, which forms the further guide 43 and the snap connection 39 with the sleeve 26.
  • the sleeve 38 which is formed in one piece with the actuating unit 5, has at least one radially inwardly projecting, cam-like snap member 41 in the region of the free end and is divided by longitudinal slots into at least two or three circumferentially adjacent shell segments which are spread apart in a resilient manner can and each have a corresponding segment-shaped snap member 41.
  • the sleeve 26 In the region of the free end, the sleeve 26 has a corresponding, radially outwardly projecting, annular collar-shaped snap member 40.
  • the snap members 40, 41 run onto one another, as a result of which the snap members 41 are expanded until they engage behind the snap members 40 in a resilient manner, so that an axially positive locking is then provided.
  • the snap members 41 can slide on the outer circumference of the sleeve 26 at the same time.
  • the pump piston 11 forms a further engagement member 44 for the mutually supportive connection of the two actuating units 4, 5. If this engagement member 44 is not a pump piston, it serves essentially only for closing or connecting the media store 10 when it is inserted.
  • the engaging member 44 projects beyond the free end of the sleeve 38, which in turn extends approximately to the free end of the cap jacket 19 or is slightly set back relative to the latter.
  • the actuation units 4, 5 are not moved back to their starting position by a spring after performing a pump stroke, but the respective axial pump stroke end position is simultaneously the axial starting position for the subsequent pump stroke, so that a gradual penetration of the pump piston 11 in the pump chamber results.
  • Each pump stroke is stop limited by a controller 45 which e.g. is formed by cam webs 46 on the outer circumference of the cap shell 18 and stepped cam grooves 47 on the inner circumference of the cap shell 19.
  • the two actuating units 4, 5 are rotated relative to one another in such a way that the cam webs 46 can come into engagement with the next, longer cam grooves 47.
  • This control 45 and possibly a display device for discharge processes thus also belong to the preassembled assembly 49, in which the media storage 10 is to be inserted subsequently.
