Definitions

  • the invention relates to a device for painting the inside of hollow bodies such as tubes, cans or the like with a transport chain with rotatable receiving chucks for the hollow bodies, the transport chain being guided at the coating location around a wheel to which a lifting carriage, which may also perform pendulum movements, with coating units attached to it by means of holders is assigned and with drives, the lifting movement of the lifting carriage being effected by an additional drive.
  • Such a device is known from CH-PS 480 879.
  • the hollow bodies are set in rotation about their axis at the coating location and the coating units attached to the lifting carriage move into the hollow bodies and paint the inner wall thereof.
  • individual drives serve to drive the transport chain and / or the wheel, the lifting carriage and to rotate the hollow bodies, the transport chain being given continuous movement.
  • the lifting carriage is arranged in such a way that it can be moved or moved along a certain distance, which is sufficient for carrying out the coating process, coaxially to the hollow bodies.
  • cams and servomotors are provided, which are designed for defined stroke lengths and movement laws and only allow constant stroke distances. If e.g. If other stroke lengths are desired, the device must be redesigned, which causes considerable downtimes of the device.
  • the coating units are moved in by a mechanical swivel curve Dependent on the transport chain drive cyclically pivoted in such a way that one or more coating units run along in one cycle during the coating process and are pivoted back into their starting position after they have been moved out of the hollow bodies to be coated.
  • the coating units are only controlled by a mechanical stroke curve without swiveling movement, it also being possible for several coating units to be extendable at the same time, the coating process taking place when the hollow bodies are at a standstill.
  • the coating process is released or not in the respective coating unit.
  • the stroke lengths in the known devices cannot be changed or can only be changed in stages by exchanging device parts, which requires the use of different devices or long downtimes to convert the devices for coating hollow bodies of different dimensions. Due to the unchanged stroke position, the position of the holders of the coating units must be changed manually if recordings with a different depth are used, which is also extremely labor-intensive.
  • a major disadvantage is that the coating speeds are dependent on the number of cycles and the specified stroke length, ie that even with short hollow bodies with small diameters, the same spraying speed must be used as with long hollow bodies with large diameters.
  • a minor one Coating speed which may be required due to special varnishes, therefore also requires a reduction in the cycle speed.
  • a change in the transport speed and thus inevitably a change in the coating speed without readjusting the coating units also results in reject production, since - regardless of whether the stroke takes place at a higher or lower speed - the same amount of paint is dispensed per unit of time, so that in one case too much Paint is used up and in the other case too little paint is applied.
  • the object of the invention is to improve a device of the type mentioned in such a way that any stroke lengths and stroke positions of the coating units can be automatically adjusted within wide limits and it is possible, depending on the needs of the coating and the coating lacquers used and the length of the hollow body, variable stroke speeds to provide.
  • the invention makes it possible to adapt the stroke length to different container lengths. The same applies to the stroke distance at different feed depths. It is also possible to change the reversal point of the lifting movement without this requiring a manual correction on the holders of the coating units. As a result, the quality of the coating can be improved in a critical area. Single or multiple coatings per stroke cycle with a selectable coating speed are possible. In addition to the usual return stroke painting, immersion painting can also be carried out. If necessary, several stroke cycles are possible within one cycle.
  • the freely selectable speed for the forward and return stroke, with the changeable stroke position and stroke length in connection with the adjustable coating path control enables optimal adaptation to hollow bodies with different lengths and diameters with regard to the desired optimal coating quality and high production figures.
  • the device can be correspondingly delayed to a standstill or accelerated to the production speed without changing the amount of paint supplied per hollow body and thus without rejects, depending on the transport speed, since the set coating speed remains unchanged.
  • the coating process can be ended, so that no rejects due to incomplete painting Hollow body is created.
  • the drive for the transport device does not need to be actuated for set-up functions with regard to the stroke path and its position or the stroke speeds.
  • the invention is based on the fact that the drive of the lifting movements is separated from the drive of the transport system and possibly the pivoting movement of the lifting carriage.
  • the lifting movement takes place directly or indirectly with the interposed mechanical transmission elements by means of a position-controlled or speed-controlled drive.
  • An electric, hydraulic or pneumatic drive can serve as the drive.
  • the transport can take place continuously or step by step.
  • the device 1a and b has a spray wheel 1, around which a transport chain 2 with rotatable receiving chucks 3 is guided.
  • the device also has a bearing 4 for a lifting carriage 5, which enables its lifting and pivoting movements.
  • the lifting carriage 5 has one or more coating units 7, for example spray guns, arranged on holders 6.
  • In the receiving chucks 3 are hollow bodies 8, z. B. cans or tubes can be arranged, which are to be coated on the inside.
  • the device has a regulated drive, for example an electric motor 9 (FIG. 1b), which can be a three-phase motor and is used to drive the transport chain 2 and, via a pendulum gear 10, to carry out the pivoting movements of the lifting carriage 5.
  • the device also has an additional position-controlled electric, pneumatic or hydraulic drive 11, which gives the lifting carriage 5 lifting movements by means of a drum curve 12 with a constant gradient.
  • a change in the direction reversal points regulates a travel path limitation or a travel path change.
  • a disc curve (not shown) with a constant gradient can also be taken as the drum curve 12.
  • the regulated drive could drive, for example, a stepping transmission with a spray plate or a transport chain with compensating loops (not shown).
  • the exemplary embodiment shown in FIG. 2 is essentially the same as the exemplary embodiment shown in FIG. 1, however the lifting movement is transmitted to the lifting slide 5 from the position-controlled drive 11 instead of via a drum curve 12 via a spindle lifting system 13, which can be a ball screw system.
  • the embodiment shown in Fig. 3 differs from that shown in FIGS. 1 and 2 only in that the coating stroke movement is transmitted by the position-controlled drive 11 via a linear module 14.
  • FIG. 4 corresponds to that shown in FIGS. 1 to 3 with the difference that the stroke movement from the position-controlled drive 11 onto the lifting slide 5 takes place by means of a directly coupled articulated lever system 15 with constant translation.
  • FIGS. 1 to 4 can be operated as a double coating station, see FIG. 5, where the exemplary embodiment according to FIG. 4 is shown as a double station.
  • the lifting movement is transmitted to the lifting carriage 5 via a drum or flat curve 16, which is driven by a speed-controlled or speed-controlled arbitrary drive, for example an electric motor 17 with or without a downstream quick-action coupling 18 for a stop and go Operation is driven.
  • a speed-controlled or speed-controlled arbitrary drive for example an electric motor 17 with or without a downstream quick-action coupling 18 for a stop and go Operation is driven.
  • a drive can also be used without reversing the direction.
  • the planetary gear 19 takes over the function of a superposition or differential gear as a summing gear and is driven for the stroke control by any drive, for example a frequency-controlled electric motor 17, and is connected by a drive wheel 20 to the drive 9 in a corresponding transmission ratio. In this way, the stroke movement is ensured until the end of the operation in the event of a drive (electric motor 17) failure.
  • the lifting movement H between the end points A and B can be superimposed on a tracking device 21 (FIG. 8) mechanically coupled to the drive for the transport chain 2, the movement sequence of which envelops all the spraying stroke movements .
  • the freely selectable stroke position and the different starting position of the controlled stroke movement require a set-up correction for the tracking device 21.
  • a tracking device 21 which serves to protect the coating units 7 from damage, is shown schematically in FIG. 8 for the exemplary embodiment according to FIGS. 4 and 5. It is dimensioned in accordance with the largest possible stroke path H and mechanically guides the possibly disturbed lifting drive (the position-controlled drive 11) into its starting position outside the collision area of the coating units 7 with the receiving chucks 3 with hollow bodies 8 of the transport chain 2.
  • a crank 23 is continuously driven by a drive shaft 24 connected to the drive of the transport chain 2.
  • a pendulum lever 25 of the tracking device 21 this movement is carried on a shaft a clutch 26 mounted thereon and a driving lever 29 transmitted.
