Definitions

  • the present invention relates to a tightness test system for rigid containers, in particular plastic bottles, in which containers supplied one after the other are tested on a rotating test table within a passage by temporarily closing the opening provided at the head of the container by means of closing devices and the interior of the container to one during the passage actual test device is connected, a gas pressure is built up in the interior of the container, stabilized and subjected to a differential pressure measurement in order to determine a possible leak and to identify a possibly leaked container.
  • the separation takes place, for example, via a separation screw or conveyor belts running at different speeds, and the entrainment is carried out via so-called stars with drivers adapted to the format of the containers.
  • the actual leak test is based on a differential pressure measurement of a gas temporarily blown into the containers for test purposes and is eg in. , , , described in detail.
  • the main problem is that the conversion of the test systems to a new format of the container to be tested is extremely complex, due to the fact that the test table, the associated rotating head with locking devices and the also rotating actual test devices form a unit that is only very large Time and with the help of specialists can be adapted to new formats.
  • the object of the complete invention was to create a leak test system which can be quickly and easily converted to new formats of the test specimens with a reasonable financial outlay.
  • the system can be converted to a new format very quickly even without the help of specialized specialists by changing the format-dependent Elements are designed as a unit and are interchangeable as such, while the remaining parts are arranged stationary in the system and remain there for each format.
  • the core of the solution lies in the rotating union between the test table or rotary head and stationary parts of the system, which enables the connection of a built-up gas volume or gas pressure from a rotating to a stationary part.
  • Figure 1 shows a leak test system according to the invention purely schematically from the front and from above, with two possible interchangeable test table rotation head units, which can be mounted in the frame of the system.
  • FIG. 2 shows a vertical section through a test table equipped with a rotary head
  • FIG. 3 shows a view of the device according to FIG. 2 from above;
  • Fig. 4 shows the frame of a test system with the fixed system parts, i.e. the test table drive, the rotary feedthrough and other stationary parts of the actual test device;
  • Fig. 5 shows the system of Fig. 4 from above
  • Fig. 6 shows a longitudinal section through the core of the invention, ie through the rotary union.
  • Fig. 1 of the drawing shows purely schematically in two views (front view and top view) of a leak test system 1 with feed and removal conveyor belt 2 or 3 for containers 4 made of plastic.
  • the system 1 essentially consists of a frame 5, in which the containers to be tested are guided to a test table 6 with driving star 7, temporarily closed during the cycle time on the test table 6 by a rotating sealing device 8 and by means of a gas pressure test (e.g. differential pressure method) during the Throughput time to be checked for leaks.
  • a gas pressure test e.g. differential pressure method
  • the measurements are carried out by means of an actual stationary test device accommodated in the control cabinet 9. Leaky containers are automatically rejected after the test system.
  • the containers to be tested are conveyed directly to and from the test table 6 by means of the conveyor belt (in other constructions, the containers are separated in front of the test table by means of a turnstile and then fed to the test table leads) .
  • containers of any dimension made of their own rigid material, such as plastic containers or bottles can in principle be checked for leaks using a test system of the type shown.
  • test device can always be used for this.
  • the drivers and the locking device must be changed or replaced.
  • the essence of the present invention now consists in designing the test table with drivers and rotary head (with a locking device) interchangeable as a unit for each format of the test specimens. Such an exchange is very simple and can be carried out very quickly even without the involvement of specialists.
  • Each test table can e.g. for 4 to 8, preferably 6 receptacles.
  • the entire unit can be easily dismantled in the machine frame and exchanged for another unit (different format) by placing it at the bottom of the central hollow shaft 16 is placed on a drive belonging to the machine.
  • FIGS. 4 and 5 show the machine frame with the drive 17, 18 for the test table (not yet attached here), parts of the stationary device are also shown which allow gas to be supplied from the stationary part to the rotating part of the system. These parts remain the same regardless of the size of the test table, i.e. they do not have to be replaced.
  • a central mandrel 21 is provided with longitudinal bores 22, 23, etc., each of which is assigned to one of the closing devices for the openings of the containers to be tested. Each of these bores 22, 23 can also be connected to gas lines for the measurements to be carried out according to the known principle.
  • the upper end of the central dome 21 is connected to the rotating parts on the underside of the test table and, for example via lines which lead through the hollow shaft 16 (FIG. 2), to the various locking devices.
  • Each longitudinal bore 22, 23 etc. leads radially outwards over a certain length, via a bore 22 ', 23' etc.
  • the mandrel 21 rotating during operation is surrounded by a number of stationary annular elements 24-28 which are clamped against one another by means of tensioning screws 29.
  • Each element 24-28 has on the inner wall an annular channel 24 '-28 * open towards the mandrel 21, so that each bore 22', 23 'etc. communicates with one of these annular channels 24' -28 '.
  • Each ring channel 24'-28 ' leads to the outside via an associated radial bore 24 "-28", so that each outlet A-E, which is connected to a specific closing device, can be connected to the test device.
  • Each ring channel 24 '-28' is sealed against the rotating mandrel 21 by suitable ring seals 30, so that unadulterated measurements are guaranteed.

Abstract

Installation pour le contrôle d'étanchéité de récipients, par mesure de pression différentielle, comprenant une table de contrôle (11) munie de moyens d'entraînement (12, 13) solidaires en rotation avec cette table, et une tête de rotation munie de dispositifs de fermeture (14) et qui est facilement interchangeable, sous forme d'une unité, en vue d'un changement de dimensions, le dispositif de contrôle proprement dit étant monté à demeure, du fait qu'il est prévu un dispositif rotatif pour le passage du gaz de contrôle.
