Definitions

  • the present invention relates to a device for checking the presence of objects and in particular of containers.
  • beverage containers In the beverage manufacturing industry, it is common for beverage containers to be produced, bottled, labeled and further processed in a multi-unit process.
  • the containers are transported, for example with rotary stars from a treatment center in another treatment unit. Often it is necessary to check whether a container is actually arranged in a certain position, for example, whether a certain gripping clamp is occupied by a container. If, for example, a gripping clip is not occupied by a container, this could result in a beverage being dispensed into a non-existent container, thereby causing contamination of a system.
  • the signal transmission from the ultrasonic transmitter to the ultrasonic receiver is interrupted and in this way the occupation status of the corresponding gripping element can be checked.
  • the previously known as the prior art sensors are usually made of plastics, such as Teflon.
  • the ultrasound transmitter has a loudspeaker on its exterior and the receiver correspondingly a microphone which receives the sound signal of the transmitter.
  • the so-called clean room area occur in some cases considerable external treatments with other liquid and gaseous media. This often leads to failures of the transmitting and receiving units and requires u. a. an intervention in the sterile area to dry the sensors.
  • the WO 2004/033305 A1 discloses a device according to the preamble of claim 1.
  • the present invention is therefore based on the object, an apparatus for checking the presence of objects, esp. Of containers, to provide, which is less susceptible to substances such as cleaning gases, especially in critical environments, such as clean room areas.
  • a device for checking the presence of objects and in particular of containers has a transmitting device which has a sound signal generating unit to generate a sound signal output and a receiving device, which is arranged with respect to the transmitting device that of the Receiving device is output from the transmitting device and transmissible by air sound signal can be received.
  • a transmitting device which has a sound signal generating unit to generate a sound signal output
  • a receiving device which is arranged with respect to the transmitting device that of the Receiving device is output from the transmitting device and transmissible by air sound signal can be received.
  • at least the transmitting device or the receiving device to a housing, wherein at least a portion of the housing for dispensing or for receiving sound signals is suitable.
  • substantially higher powers are preferably used than in the case of transmitting and receiving units customary in the prior art.
  • both the transmitting and the receiving device each have a housing, and the housing of the transmitting device is for delivering a the housing of the transmitting device is suitable for delivering a sound signal and the housing of the receiving device for receiving a sound signal.
  • the sound signal is preferably an ultrasound signal.
  • both the speaker unit and the microphone unit which are provided in the prior art on the outside of the housing, are replaced.
  • At least one housing is completely closed.
  • the inner region of this housing which also contains, for example, the control devices and the like, can be protected in a particularly advantageous manner.
  • the housing has a base body and a head welded onto this base body, so that after the welding operation, the housing is essentially irreversibly closed.
  • a transducer device is arranged in the interior of the housing of the transmitting device, which converts electrical oscillations, in particular into mechanical vibrations, and thus generates, for example, an ultrasound signal.
  • This transducer device may on the one hand be a loudspeaker which is arranged in the interior of the housing, but other sound-generating devices would also be conceivable.
  • a coil could be coupled directly to the housing or to a portion such as an end wall of the housing.
  • a further converter device is arranged in the interior of the housing of the receiving device, which converts mechanical or acoustic vibrations back into electrical vibrations.
  • this transducer device for example, in mechanical contact with a portion of the housing such as a wall of the housing, stand and work much like a microphone.
  • the housing of the transmitting device has a first wall section with a first predetermined wall thickness and a second wall section with a second predetermined wall thickness, wherein the second wall thickness is less than the first wall thickness.
  • a main body of the housing is made with a thicker wall thickness and a head or front end of the housing with a thinner wall thickness. This thinner wall thickness can be excited to vibrate, and in this way, for example, an end face of the housing can act similar to the membrane of a speaker.
  • these two wall sections are welded together.
  • a second wall section is preferably a cover of the relevant housing.
  • the housing of the receiving device may also have a first wall section with a first predetermined wall thickness and a second wall section with a second predetermined wall thickness, wherein the second wall thickness is less than the first wall thickness.
  • the second wall thickness can be used to record acoustic signals and thus be excited to mechanical vibrations.
  • At least one housing is made of stainless steel.
  • both the transmitting device and the receiving device are preferably designed in all-steel, and particularly preferably in a hygienic design for the detection of individual containers.
  • the transmitting device is arranged on a holder, and the transmitting device has an oscillatable region for outputting the sound signal, wherein the holder is arranged at a region of the transmitting device at this, which is spaced from the oscillatable region.
  • the transmitting device can be brought into a specific position.
  • the holder is arranged in contrast in a different area, so that the resulting vibrations are not damped by the holder.
  • the holder is arranged in a region of the transmitting device which, although not the oscillatable region itself, but adjacent to this. In this way, a particularly stable mounting of the transmitting device can be provided.
  • the receiving device is arranged on a holder and the receiving device has an oscillatable region for receiving the sound signal, wherein the holder is disposed at a portion of the receiving device at this, which is spaced from the oscillatable region.
  • the holder is not applied to the oscillatory region itself, in turn, to prevent damping by the holder.
  • At least one housing and preferably both housings have an edgeless outer contour.
  • Such edgeless contours are easy to clean and liquids can easily slide off these edgeless surfaces.
  • the housings preferably each have a cylindrical cross-section and particularly preferably end surfaces with rounded edges.
  • each of the second wall section of the two housings is a cover or an end face of this housing.
  • This face is particularly well suited for the output of sound signals and also for their recording.
  • the transmitting device and the receiving device are arranged on a common carrier.
  • this carrier is preferably designed such that mechanical vibrations generated by the transmitting device are not transmitted mechanically via the carrier to the receiving device.
  • the transmitting device according to the invention must radiate with much higher power, since - as mentioned - a portion of the housing is excited to vibrate. This can lead to the fact that the entire carrier or the region on which the transmitting device is arranged is also excited to vibrate and these vibrations are transmitted directly to the receiving device.
  • the receiving device would register the receipt of a signal, even if a bottle is arranged between the transmitting and the receiving device, since this signal has been transmitted via the carrier. Therefore, the carrier preferably has damping units which prevent a direct transmission of mechanical vibrations to the receiving device.
  • the present invention is further directed to a plant for treating containers with a transport device which transports the containers along a predetermined transport path and at least one device of the type described above.
  • This system for treating containers may in particular, but not exclusively, to a plant for filling containers, for labeling containers, for transporting containers, for blowing containers and combinations thereof and the like act.
  • Fig. 1a shows a plan view of a system according to the invention 100.
  • This system 100 has a transport device 102, here a transport star, on whose outer periphery a plurality of gripping elements 104 are arranged, which are each capable of containers 10 to reach at their mouths.
  • This transport device 102 rotates in a preferred direction, here for example counterclockwise.
  • this system has a device 1 according to the invention, which determines whether in each case containers 10 are arranged on the gripping elements.
  • Fig. 1b shows a partial view Fig. 1a along the line AA Fig. 1a , More precisely, is in Fig. 1b a plan view of the device 1 according to the invention shown.
  • This device has a transmitting device 2, which outputs a sound signal, and in particular an ultrasonic signal.
  • a receiving device 12 can record this ultrasonic signal, which moves in particular in the direction S.
  • the transmitting device 2 and the receiving device 12 are arranged on a common carrier 60.
  • This carrier 60 is in turn arranged on brackets 62, cross bars 64 and other brackets 66 on a support bar 68.
  • This holding rod 68 is in the region of the transport device 102 and a sleeve 108 of the Rotary shaft of the transport device 102 fixed, ie stationary, arranged.
  • Fig. 2 shows a detailed perspective view of the in Fig. 1a shown arrangement.
  • the transmitting and receiving device 2, 12, shown, these two devices are externally designed similar and each case 8, 18, have.
  • These housings 8, 18 each have end faces, but only the end face 34 of the transmitting device 2 is shown.
  • the end faces 34 have - as mentioned above - a smaller wall thickness than the other areas of the housing 8. At the same time, this end face or the lid 34 can be excited to vibrate and in this way emit the sound signals.
  • the reference numeral 50 refers to a holding device for arranging the transmitting device 2 on the carrier 60.
  • the reference numeral 61 refers to a cross-connection of the holding device 60 in order to space the transmitting device 2 from the receiving device 12.
  • the carrier 60 is designed in such a way that it can not itself be induced to oscillate, in particular in the frequency range of the emitted sound vibrations.
  • Fig. 3 shows a page representation of in Fig. 2 shown device. It can be seen that the respective end faces 34 and 44 of the transmitting device 2 and the receiving device 12 are directly and at the same height opposite, so that the sound signal can be transmitted in a particularly favorable manner, as long as no container 10 is in the intermediate region between the transmitting device 2 and the receiving device 12. It is possible that the transmitting device 2 outputs its signal controlled, that is, that the output of this ultrasonic signal is adapted to a rotation of the transport device 102, and only in each case a signal is output when a container between the transmitting device 2 and the receiving device 12 is expected. However, it would also be possible for the ultrasonic signal to be output continuously.
  • Fig. 4 shows an enlarged view of in Fig. 3 shown view. It can be seen here, the two holders 50, with which the transmitting device 2 and the receiving device 12 are arranged on the carrier 60.
  • This holder 50 preferably has a flexible ring 52, which surrounds the housing 8 of the transmitter together with the holder 50. With this flexible ring 52 vibrations of the housing can be damped. A corresponding arrangement is also located at the receiving device 12.
  • FIG. 5 shows an enlarged view of the receiving device 12.
  • the housing has a first wall portion 42, which also forms the main body of the housing 18.
  • the second portion 44 is arranged with the thinner wall by means of a welded joint 48.
  • Much of the electronics of the transmitter is located inside the body 42.
  • a transducer means (not shown) may be attached to the second portion and In particular, the end face 44 may be coupled to absorb vibrations.
