Definitions

  • the present invention relates to an apparatus for internal can processing with an internal canning arm, comprising a connecting arm and a section with a spray head for the internal coating of cans, and to a use of the apparatus for connecting a can seam coating head to an arm of an internal seam coating system.
  • DE-OS 2 236 140 describes a conventional internal coating system for cans as is known from a number of similarly arranged patents or technical publications. If, for example, another coating medium has to be applied to the inside of the can in the coating system described, this is normally not possible with the same spray head, which means that the whole of the coating systems of the type described in DE-OS 2 236 140 in a complicated and time-consuming manner Spray arm must be removed to be replaced by another arm.
  • DE-A 3 215 372 describes a plug-in connection for medical and dental technology devices, both electrical plug-in connections and hose connections being pluggable.
  • a perforated plastic washer which serves as a sealing washer, with one plug end of each of the lines to be connected protruding through a corresponding hole in the washer and into a funnel at the other plug end, the funnel sealing against the washer is pressed.
  • This connector which is well suited for medical and dental technology, is quite complicated in its structure and should hardly be suitable as a connector for the quick replacement of inner coating arms.
  • the media used in the coating such as wet paints, powder coatings, etc., place very high demands on connecting the coating arm to the coating system, which is clearly evident from the massive construction, as proposed in DE-OS 2 236 140 becomes.
  • the object of the present invention is therefore to provide a device which enables the rapid replacement of such a section in an internal can processing system.
  • a device preferably comprises a flat or curved contact surface on the section, such as on the spray arm, and on the arm of the system to which the section is connected, and at least one locking element that presses the contact surfaces together.
  • positioning elements are further preferably provided on the contact surfaces, which allow the locking actuation of the locking element only in a predetermined relative position of the two surfaces.
  • the locking member is a non-slip plug.
  • the length of the plug or. of the corresponding sleeve can be designed such that no displacement of the section relative in the inserted state to the arm is possible.
  • either the surface of the connector or the inside of the sleeve is formed with a material with high surface friction, so that the highest possible frictional resistance between the sleeve and connector.
  • the material can be plastic or rubber-like materials, for example.
  • the sleeve and plug can only be pulled apart by the action of an external force.
  • the device according to the invention is particularly suitable for connecting a can seam coating head as a section to an arm of a can coating system.
  • Fig. 1 is a quick coupling between a spray arm 1 and a connecting arm 2 of a can seam coating system.
  • Contact surfaces 3 and 4 which are pressed together, are provided on the front of both the spray arm 1 and the connecting arm 2.
  • a union nut 8 is rotatably arranged, which engages with an internal thread 10 in an external thread 12 of the spray arm 1.
  • the knobs 9 projecting from the union nut can be pushed over the external thread 12 of the spray arm 1, for example, by being arranged in a resilient manner, for example through axial slots on the union nut 8.
  • Supply and discharge lines 6 between spray arm 1 and connecting arm 2 are connected in a sealing manner via contact surfaces 3 and 4.
  • the union nut 8 is loosened until the two contact surfaces 3 and 4 can be separated from the spray arm 1 and the connecting arm 2.
  • the spray arm 1, which has been used, for example, to coat larger areas, is now removed and replaced, for example, by a spray arm, for coating smaller areas.
  • the new spray arm 1 is placed with its contact surface 3 on the contact surface 4 of the connecting arm 2. Now the union nut 8 is screwed in and the two contact surfaces 3 and 4 are pressed.
  • Positioning pins 14 (FIG. 2) and corresponding bores each on the contact surfaces 3 and 4 ensure that the two contact surfaces 3 and 4 have to be placed against one another in such a way that the corresponding feed and discharge lines 6 are aligned with one another before they can be pressed.
  • the line connections are made operationally reliable, such as sealing, by the tensile action of the union nut 8, and the new spray arm 1 can be put into operation.
  • the contact surface 3 comprises a sealing ring 16 on its periphery.
  • An electrical connection 6e is established by a commercially available plug socket and a corresponding sleeve in the opposite contact surface.
  • a line 6a is, for example, a light guide.
  • Line 6b is provided for the transport of powder coatings and air, line 6c for the suction of the non-adhering powder.
  • Line 6d for the supply of wet paint is provided in order to enable a powder coating head to be exchanged for a wet paint coating head as a section.
  • the line 6f is provided in order to ventilate a section of a coating head with high-voltage electrodes so that they do not become encrusted with coating medium.
  • a seal 18 is provided at their mouths in the surfaces 3 or 4, which ensure the connections in a sealed manner.
  • the positioning pins 14 are guided into the corresponding recesses in the contact surface of the connection arm. Due to the positioning effect of the pins / recesses, corresponding lines 6 are aligned on the contact surfaces and become operationally reliable when locking, e.g. sealing, connected.
  • 3 and 4 show further possibilities for connecting a section to an arm by means of a quick coupling.
  • a portion 21 is locked to an arm 22 using a bayonet catch.
  • a pin 26 of section 21 is inserted through an insertion recess 27 into a guide 28 of a collar 25 of arm 22.
  • the pin 26 slides along the guide 28 and the two contact surfaces 23 and 24 are pressed together.
  • the pin 26 is fixed in the end position shown in FIG. 3 by means of a terminal recess in the guide 28, as a result of which the two contact surfaces 23 and 24 remain pressed.
  • FIG. 4 shows a plug connection between a section 31 and an arm 32.
  • a plug 36 of the section 31 is inserted into a sleeve 35 of the arm 32 until the contact surfaces 33 and 34 meet.
  • the surface 37 of the plug 36 as well The inside 38 of the sleeve 35 is coated with a material which has a high surface friction resistance. Due to this high surface friction resistance, plug 36 and sleeve 35 can only be unlocked from the locked position shown in FIG. 4 by external application of force, for example by external pulling apart of the two elements.
  • the device according to the invention is generally applicable to any type of internal machining system where there is a need to interchangeably connect an arm section.
