Definitions

  • the invention relates to a method for separating reusable bottles, in particular plastic reusable bottles, from the reusable circulation in which bottles returning for filling are each checked by a test device for the presence of fatigue damage. Such a method is known from DE-C-3 626 775.
  • the invention further relates to a device for performing the method.
  • the task therefore is to create a possibility that bottles can be removed from the reusable circulation in good time before their end of life, without the bottles being removed from the reusable circulation much too early.
  • the respective bottle is provided with a first marking or not, that in each case a bottle already provided with at least one such marking is determined and at least one further marking is applied with each return, and those bottles, the number of markings of which is predetermined Value reached, to be eliminated from circulation.
  • Each bottle that has reached the clearly recognizable degree of damage is preferably granted 8 to 15, in particular ten, round trips.
  • the test for the predetermined degree of damage is preferably carried out by an optical test, in particular by an image processing method.
  • FIG. 1 a section of the bottle bottom of a plastic bottle is shown in cross section. Some of the cracks 1, 2, 3 and 4 resulting from the fatigue of the material are shown schematically as examples. It is known that the plastic bottles produced in the blow molding process have relatively high tensions in the base area. When such bottles are subjected to the usual stress during cleaning, filling and normal use, a large number of fine cracks arise in the bottle material, in particular in the bottom area of the bottle. The number and depth of the cracks increases over the life of the bottle. This leads to the bottle becoming defective after an indefinite number of reusable cycles. In particular, this can occur during filling, in which the bottle is under a relatively high pressure, e.g. 8 bar, is exposed.
  • a relatively high pressure e.g. 8 bar
  • the density distribution of the cracks in the floor area has proven to be suitable as a criterion for the existence of fatigue damage which can be recognized by the test device.
  • the absolute frequency and / or the length of the cracks could also be determined, for example.
  • the marking is preferably applied to the respective bottle in which the predetermined degree of damage has been determined by a laser.
  • the application of a code on bottles for other purposes is known per se. Processing and marking with lasers is also known in principle, for example reference may be made to US Pat. No. 4,128,752. It is particularly preferred if the markings are recorded with the same test device, that is to say in particular with the image processing device, which is also used for the detection of the fatigue cracks. A particularly simple execution of the method then results.
  • the detection of the fatigue cracks and the detection of any markings that have already been applied can also be carried out separately.
  • Another optical detection method can be used for the detection of the damage, for example, which uses the reflection properties of the bottle bottom, or the damage can be detected by ultrasound testing.
  • the markings can also be counted in another way, for example by optical scanning.
  • the markings can of course also be applied differently than with a laser, for example using a printing process.
  • FIG. 2 shows, in a highly simplified manner, a flow chart for the separation of bottles according to the method, an image evaluation method, for example according to the publication DE 40 27 992, being used.
  • an image is taken from the bottle base and this is evaluated. If at least one marking already exists, which is determined by the recording of the image, it is checked whether the number of markings has already reached a defined value, in particular the preferred value of ten. If this is the case, that is to say if the bottle already has ten markings or ten counted returns, the bottle is eliminated or registered as a bottle to be eliminated later along the conveying path and the next bottle is checked.
  • the number of markings is below the defined value, in particular below the value specified as the preferred example, ten, a further marking is applied and the bottle is left in circulation. If it is found that there is still no marking on the bottle, it is checked whether the damage to the bottle bottom has already reached a predetermined level. For example, the image taken is used to check whether the crack density is greater than a predetermined value. If this is not the case, the bottle is left in circulation without any further measures. If the crack density has reached the predetermined limit value, the first marking is applied to the bottle. This bottle will therefore only be able to carry out a predetermined number of cycles before it is eliminated.
  • the number of 8 to 15, in particular ten, cycles from the predetermined value of the recognizable damage has proven to be particularly advantageous. With ten further rounds, it is practically ensured that the bottle does not fail. In contrast, even with a slightly higher number of circulation, Most likely to fail. Of course, the number of revolutions still to be allowed depends on how the predetermined degree of recognizable damage is defined. It has been shown that the increase in damage can be clearly recognized to a certain extent by means of image processing. From this degree of damage or limit value, the further increase is no longer clearly recognizable. When using the image processing method, as described in DE 40 27 992, and with such plastic bottles as are usually used today, namely with PET bottles, there is a relatively precisely determinable degree of damage from which the further rounds are to be paid. This is because the existence of this degree of damage, in which a further increase in damage is no longer clearly discernible, is chosen as the starting time for counting.
  • Figure 3 shows an inspection machine for plastic bottles, as is known from DE 40 27 992.
  • the machine has an inlet carousel 12 and an outlet carousel 14. Between the carousels 12 and 14 there is a main carousel 16. Each station of the main carousel 16 is equipped with a complete test unit for volume and leakage measurement, height measurement, straightness measurement, muzzle slope measurement and residual liquor control not described here in detail.
  • the bottles 10 are fed to the inlet carousel 12 through an inlet screw 18. On the outlet side, the bottles 10 are guided out of the machine again by means of an outlet screw 20.
  • a camera box 22 for code reading is arranged above the outlet carousel 14.
  • the camera box 22 contains a camera 24, of which only the lens is visible.
  • An illumination source 32 is arranged opposite the camera 24, by means of which the bottom of the bottle, which is located between the illumination source and the camera, is illuminated uniformly.
  • the camera 24 is so on the bottom
  • the area of the bottle 10 focuses so that the fatigue cracks and a marking string 34, which is applied to the outer wall of the bottle in the area between the bottom of the bottle and the height where the size of the bottle is largest, are included from the inside of the bottle.
  • the camera 24 takes a picture of the bottle bottom including the adjacent lower region of the bottle side wall as a snapshot. This snapshot is assigned to the respective bottle and is upgraded, as has been explained, for example, in FIG. 2.
  • the bottle is either marked with a laser or not, or the bottle is ejected from the further conveying path by an ejector, for example with compressed air.
  • an ejector for example with compressed air.
  • Such marking devices both with laser and with color printing, on the other hand, are well known. Ejectors are also known in various variants.
