Definitions

  • the invention relates to a device for applying a flowable medium on a surface of an object along a non-circular shape Order curve according to the preamble of claim 1.
  • Tin cans the contents of which are to be packed airtight and / or liquidtight mostly closed with attached lids by flanging the edge of the lid.
  • the edge of the lid is provided with a rubber coating to provide the required tightness.
  • the lids corresponding to the circular shape are prepared by gumming no problems at the edge.
  • DE 21 56 238 describes this Purpose to arrange a nozzle firmly and to rotate a lid around its axis.
  • the angular velocity that the area to be applied be constant if possible.
  • the invention has for its object a simple, fast-working Device for applying a flowable medium to a surface along a curved, deviating from the circular shape to create a high Throughput speed enabled.
  • the invention is essentially based on the application of a rubber coating described on non-circular cover, but is in no way limited to this. she captures all coatings with any flowable and coating-compatible media along a spell curve that deviates from the circular shape.
  • the holding device or receiving device for the object to be coated e.g. cover, immovable, i.e. the lid is kept immobile during the coating process.
  • the handover the lid in the holding device and its removal can therefore be within in the shortest possible time and without any special equipment.
  • the application device e.g. a nozzle, does not need to be in a certain starting position, can rather be constantly moved.
  • the application is then done by controlling the coating medium controlled, e.g. via a corresponding valve. This mode of operation also saves time and benefits the cycle time.
  • the device according to the invention provides a control curve, which by a Curve follower is scanned.
  • the movement of the curve follower is a linear motion transmitting gear coupled to an applicator, which applies the coating medium to the object.
  • the coating device is formed by at least one nozzle through which the medium is applied to the surface to be coated.
  • Gearbox with which to move one element can be transferred to another element, for example suitable ones Lever gears or the like are known per se.
  • the control curve is preferred in line with the order curve, i.e. it has the same shape. This is however not mandatory. It is also conceivable to use a suitably designed one Gearbox to provide a control curve deviating from the order curve.
  • the cam follower is driven by a drive device so that the cam follower moves along the cam track.
  • the drive device is now preferred executed so that the cam follower the cam track at constant speed drives along. Especially when between the control curve and application path curve Congruence exists, it is ensured in a simple manner that the application device through the corresponding coupling with the curve follower a constant Has web speed.
  • the drive device preferably contains a suitable motor which drives the cam follower either via a cam gear or via a numerical control.
  • Cam gears with which a path-dependent speed change is obtained on the output side are known per se.
  • the use of a numerically controlled drive is particularly preferred.
  • the constant web speed can be programmed accordingly regardless of the course or for any course of the Reach the control path curve.
  • the course of the job curve changes other lid shapes is simply a corresponding reprogramming of the numerical Control.
  • the device according to the invention is therefore with little effort and within a very short time you can convert the coating of a workpiece along another path curve possible.
  • the application device is used, for example the nozzle moves.
  • the movement takes place in a relatively limited space Scope instead, namely according to the extent of the job curve.
  • suitable device is not problematic.
  • the source for that medium to be applied must be permanently connected to the application device.
  • the Connection can be made easily using a flexible cable.
  • control cam it is conceivable to arrange the control cam so that it can move and the cam follower to be stationary or to let both move. According to an embodiment of the invention, however, it is advantageous if the control cam is stationary and the cam follower is movable a holding component is mounted, which in turn from the drive device by a Axis is driven to rotate.
  • the curve follower becomes of the invention from a coercive means, e.g. a further control curve, preferably a spring kept in constant engagement with the control cam. Since, as mentioned, the Control curve deviates from the circular shape, the holding component moves, the applicator holds, relative to the axis of rotation about which the holding member rotates is, for example by means of a numerical drive.
  • two are arranged at a distance from one another Control curves provided with one curve follower each.
  • the holding components of the curve followers are driven in rotation by the drive device, and the Curve followers are hinged to a rigid bridge to which the application device is attached is.
  • the holding component is preferably a carriage which is on a linear Carriage guide is slidably mounted, the carriage guide about the axis is rotatably mounted.
  • the applicator does not rotate about itself. It will therefore no swivel couplings or the like is required. It is conceivable to design the control curve in such a way that the cam follower, for example a pair of rollers, between two cam surfaces, which run parallel to each other, is positively guided. It is also conceivable that Curve follower on the outside of a preferably closed cam track to arrange. In contrast, the arrangement of the curve follower on the inside is preferred the control curve. To maintain the constant engagement of the curve follower with The control cam track is preferably provided with a spring, which follows the cam follower presses against the control curve.
  • the kinematics are only relative small masses required. Since a constant web speed is also used, The driven parts only require the force required to overcome the friction are necessary. Small cycle times can therefore be realized.
  • the constructive embodiment of the invention described last is particularly then advantageous if a plurality of application devices, for example, on the bridge Order nozzles is arranged so that a corresponding number of objects for Example cover, at the same time be provided with a rubber coating or coating can.
  • the holding member is hinged to a first beam, the in two spaced ⁇ coupled 'bearings linear along a first axis is guided, with at least one bearing in two spaced-apart fixed bearings along is guided to the first axis perpendicular to the second axis.
  • One connected to a first camp Guide bar can span a rigid triangle with the second first bearing. This is the simplest construction of a precise translation between Tax and order curve.
  • the first two can also be provided Bearings to be provided with a guide beam, each in two spaced second Storage is guided along a second axis.
  • each in two spaced second Storage is guided along a second axis.
  • the device shown shows a possibility for gumming lid edges. As already mentioned above, however, the invention is not restricted to this application, rather, any coatings can be made along a curve will. With regard to Fig. 1, it should also be mentioned that the holding or receiving device for the cover is omitted for illustration purposes.
