Description

 The invention relates to a container monitoring system for sampling and determining the presence of certain substances, for example, residues of contaminants in containers, for example in glass or plastic bottles. More specifically, the present invention relates to an improved system for sampling and analysis and a method for determining the presence of residues of contaminants in containers, for example in beverage bottles, quickly moving along the conveyor past a monitoring unit in a container sorting system.

 Known automatic chemical analyzer (EP, patent 0087028, class G 01 N 35/02, 08.31.83, 32 pp.), Which is a prototype that describes a method for sampling and determining the presence of volatile contaminants in a container that was previously filled drink and has an opening, including using a pump for extracting a sample of volatile substances from the tank.

 In the production of beverages, products are packaged in containers that are returned after use, washed and refilled. Typically, refillable containers, such as beverage bottles, are made of glass that can be simply cleaned. Such containers are washed and then monitored for the presence of a foreign substance.

 Glass containers have the disadvantage that they are fragile and, being large in volume, have a relatively large weight. Accordingly, it is highly desirable to use plastic containers, since they are less fragile and lighter than glass containers of a similar volume. However, plastic materials tend to absorb many organic compounds that can later be released into the product, thereby potentially adversely affecting the quality of the product packaged in the container. Examples of such organic compounds are nitrogen-containing compounds, for example ammonia, organic nitrogen compounds and hydrocarbons, including gasoline and various cleaning fluids.

 The basis of the present invention was the task of developing such a method of sampling and determining the presence of volatile pollutants in the tank, in which sampling and determining the presence of volatile pollutants in the tank would be carried out in such a way as to determine the presence or absence of a wide range of specific substances, for example contaminants such as nitrogen-containing compounds and hydrocarbons in containers when these containers are quickly moved along the conveyor on the way to or from the washer or such a device, sampling and analysis of residues in containers, when containers move along the conveyor without stopping their movement or any delay in movement, so that high sampling rates of about 200-1000 bottles per minute can be achieved, as well as moving along the conveyor without contacting a controlled containers with any of the mechanisms for sampling and analysis and without the physical introduction of any probes or similar devices in the tank, and a wide range of contaminants was detected in the tank for drinks with minimal mutual influence from volatiles of the residues of the beverage ingredient (“product”) in containers.

 This is achieved by the fact that the method of sampling and determining the presence of volatiles of some contaminants in a container that was previously filled with a drink and has an opening, comprising extracting a sample of volatile substances from the container using a pump, according to the invention, comprises the steps of: storing said container, the opening of which made with the possibility of closing the lid, with the lid removed for a sufficient period of time to allow volatile substances of the residue to evaporate and exit the specified container, removed by means of the drain pump sample of volatiles remaining in the container after expiration of said sufficient period of time and analysis of the sample extracted using a suction pump, for determining the presence or absence of certain contaminants therein.

 The indicated analysis step may include the steps of: mixing a sample with a chemical reagent to cause a chemical interaction between them to generate chemiluminescence of the reagents, and analysis of radiation emitted by the chemiluminescence of the sample and reagent, to determine the presence or absence of these volatile substances of some contaminants without mutual influence from chemiluminescence of volatile substances of the drink.

 Preferably, the analysis step includes the steps of: filtering the radiation emitted by the chemiluminescence of the sample, to detect the presence of radiation having a wavelength above about 0.19 microns, and to identify the presence or absence of these certain contaminants from radiation detected at characteristic wavelengths above approximately 0.19 μm.

The method may include an additional step of heating the sample to a temperature of about 400 - 1400 ^o C before the specified step of mixing and that the specified chemical reagent was ozone.

 A sufficient period of time may be approximately 15 hours.

 This is also achieved by the fact that the method of sampling and determining the presence of volatile substances of some contaminants in a container that was previously filled with a drink and has an opening, including pumping fluid into the opening of the container and extracting a sample of volatile substances from the container, with the pump opening, the opening of which is open for a sufficient period of time to allow the volatiles of the residues to evaporate and exit the specified tank, injecting fluid into the opening of the tank after the expiration of the specified an exhaustive period of time to displace at least a portion of the volatile substances from it, extracting a sample of the volatiles remaining in the tank after a specified enough time has elapsed by means of a pump, and analyzing the sample extracted by the pump to determine whether or not it contains some pollution.

 The indicated analysis step may include the steps of: mixing a sample with a chemical reagent to cause a chemical interaction between them to generate chemiluminescence of the reagents, and analysis of radiation emitted by the chemiluminescence of the sample and reagent, to determine the presence or absence of these volatile substances of some contaminants without mutual influence from chemiluminescence of volatile substances of the drink.

 Preferably, the analysis step includes the steps of: filtering the radiation emitted by the chemiluminescence of the sample, to detect the presence of radiation having a wavelength above about 0.19 μm, and to identify the presence or absence of these certain contaminants from radiation detected at characteristic wavelengths above about 0, 19 microns.

The method may include an additional step of heating the sample to a temperature of about 400 - 1400 ^o C before the specified step of mixing and that the specified chemical reagent was ozone.

 A sufficient period of time may be approximately 15 hours.

 This is also achieved by the fact that the method of sampling and determining the presence of certain substances in a container that was previously filled with a drink and has an opening, according to the invention comprises the steps of: storing said container, the opening of which is configured to close the lid, with the lid removed over time sufficient to evaporate and remove volatiles of the beverage from the container, displacing part of the contents of the container to form a sample cloud in areas outside the container near its opening, and analysis of the sample cloud in areas outside the container near its opening, and analysis of the sample cloud to determine the presence or absence of certain substances in it.

 In addition, this is also achieved by the fact that the method of sampling and determining the presence of volatile certain contaminants in a container that was previously filled with a drink and has an opening, according to the invention comprises the steps of: storing said container, the opening of which can be closed with a lid, with the lid removed for a time sufficient to evaporate and remove volatile beverage residues from the container, extracting for analysis a sample of volatile substances remaining in the container after the specified sufficient Heat-time, without further pretreatment to remove volatile residues beverage to avoid interaction of residues and impurities determined, and analysis of the extracted sample to determine the presence or absence of certain contaminants therein.

 An additional scope of applicability of the present invention will become apparent from the following detailed description. However, it should be understood that the detailed description and specific examples showing preferred embodiments of the present invention are provided for explanation only, as various changes and modifications will become apparent to a person skilled in the art from the detailed description within the spirit and scope of the present invention.

The present invention will become more apparent from the following detailed description and the accompanying drawings, given for illustration only and thus not limiting the present invention, in which:
FIG. 1 is a schematic block diagram of a system of the present invention for sampling and analyzing residues, illustrating a plurality of containers moving in order along a conveyor system through a monitoring unit, a rejection device, and a washer;
FIG. 2 is a block diagram illustrating a possible embodiment of the system of FIG. 1 in a detection system in which a detectable contaminant can be a nitrogen-containing compound;
FIG. 3 is a graph of signal intensity versus wavelength of detected radiation emitted by chemiluminescence in the analyzer of the system of FIG. 2.

In FIG. 1 illustrates a conveyor 10 moving in the direction of arrow A, having a plurality of unclosed, spaced open containers C (for example, plastic beverage bottles with a volume of approximately 1,500 cm ³ ) placed on it to move in order through the control unit 12, rejection device 28 and conveyor 32 to the washer. The contents of containers C will typically include air, volatiles of contaminant residues, if any, and volatiles of any products, such as drinks that were in containers. An air injector 14, which is a source of compressed air, is provided with a nozzle 16 spaced apart but combined with a container C in the control unit 12. This nozzle 16 is placed outside the containers and does not contact with them. The nozzle 16 directs the compressed air into the container C to expel at least a portion of the contents of the container, so as to thereby release a cloud of sample 18 to a controlled outer region of the container.

The volume of pumped air through nozzle 16 into container C will typically be on the order of about 10 cm ³ for bottle speeds of about 200 to 1000 bottles per minute, a speed of 400 bottles per minute is preferred and compatible with conventional filling rates for beverage bottles. The required control speed may vary depending on the size of the controlled and refillable bottles.

Only approximately 10 cm ^{3 of the} contents of the container will be displaced in the area outside the bottle to form a cloud of sample 18.

 A suction pump sampler 22 is also provided, which may comprise a vacuum pump or the like connected to a sampling pipe or pipe 20. This pipe is installed close to, and preferably downstream (e.g., about 15 mm) from the air injector 14 so so that there is a connection with the fluid of the cloud of sample 18 adjacent to the hole on top of the tank C.

 Neither the nozzle 16 nor the pipeline 20 is in contact with the tanks C in the installation 12 for monitoring, and both are placed at a certain distance in the position outside the tanks in close proximity to their holes. This is advantageous in that it does not require physical connection with containers C or introducing probes into containers that would slow their rapid movement along conveyor 10 and thus slow down sampling rates. Using the system and method of the present invention, high-speed sampling rates of about 200 to 1000 bottles per minute are possible. To achieve such speeds without stopping or slowing down the bottles in the control unit, the conveyor 10 preferably has a continuous drive.

 A bypass pipe 24 is provided in connection with a sample pump of the evacuation pump, so that a predetermined portion (preferably approximately 90) of the sample from the cloud 18 entering the pipe 20 can be diverted through the bypass pipe 24. The remaining sample passes to the residual analyzer 26, which determines if whether any specific substance, and then released. One goal of diverting most of the sample from the cloud 18 is to reduce the amount of sample passing from the sampler of the evacuation pump 22 to the residue analyzer 26 in order to achieve a high analysis rate. This is done to provide easily controlled levels of controlled samples with a 26 residue analyzer. Another purpose of withdrawing a portion of the sample is to essentially remove the entire cloud of sample 18 with a pump 22 from the inspection area and drain excess through the bypass 24. In a preferred embodiment, the excess sample passing through the bypass 24 returns to an air injector 14 for introduction into subsequent containers moving along the conveyor 10 through the nozzle 16. However, it will also be possible to simply lay the ventilation bypass pipe 24 into the atmosphere.

 A microprocessor controller 34 is provided for controlling the operation of the air injector 14, the evacuation pump sampler 22, the residual analyzer 26, the reject device 28, and the optional fan 15. A capacitance sensor 17 including a side source of radiation and a photodetector is placed opposite the reflector (not shown) through the conveyor 10. The sensor 17 informs the controller 34 when the tank reaches the installation for monitoring and abruptly interrupts the radiation beam reflected to the photodetector. An optional fan 15 is provided to generate a stream of compressed air towards the cloud of sample 18, and preferably in the direction of movement of the tanks C, to help remove the cloud of sample 18 from the vicinity of the control unit 12 after sampling from each tank C. This purifies the air in the area installations for monitoring so that there are no retaining residues from the existing cloud of sample 18, which can contaminate the area of the installation for monitoring when subsequent tanks C reach the installation for monitoring for tbora samples. Thus, sample transfer between containers is prevented. As schematically shown in FIG. 1, the cycle of operation of the fan 15 is controlled by a microprocessor 34. It is preferable to continuously control the fan 15 throughout the entire control time of the remaining system.

 The reject device 28 receives the reject signal from the microprocessor controller 34 if the residual analyzer 26 determines that a particular container C is contaminated with residues of various undesirable types. The rejection device 28 discharges the contaminated rejected bottles onto the conveyor 30 and allows uncontaminated acceptable bottles to pass to a washer (not shown) on the conveyor 32.

 An alternative is to place the bottle control unit down the processing chain of the bottle washer in the direction of conveyor movement or place an additional control unit and a system for sampling and analyzing residues from the washer. In fact, it may be preferable to place the inspection unit and the system after the washer while inspecting the bottles for some contamination. For example, if the contaminant is a hydrocarbon, such as gasoline, which is insoluble in water, it is easier to detect hydrocarbon residues after the bottles have been washed. This is true because during the washing process, in which the bottles are heated and washed with water, water-soluble chemical volatile substances are desorbed from the bottles by heating them and then dissolved in washing water. On the other hand, some non-water-soluble hydrocarbons can then be sampled down the process chain from the washer to exclude dissolved, water-soluble chemicals. Therefore, the detection of such hydrocarbons can be performed without potential interference with other water-soluble chemicals if the bottles pass through the washer before inspection.

 In FIG. 2 illustrates a specific embodiment of a detection system for use with the selection and analysis system of FIG. 1, in which like reference numbers indicate like details. As illustrated, a nozzle 16 is provided for forming a jet of compressed air that passes into a controlled tank (not shown). The air passing through the nozzle 16 may be heated or unheated, and for some applications it is advantageous to heat the air. Near the nozzle 16 is an inlet pipe 20 for sampling, including a filter 40 at its outlet for filtering out particles from the sample. Suction into the pipe 20 is provided from the suction side of the pump 82 connected through an analyzer 26.

A portion of the sample (e.g. 90 to 96% of the total sample stream, approximately 6000 cm ³ per minute), as described in connection with FIG. 1 is diverted through the bypass pipe 24 by connecting to the suction side of the pump 46. The pump 46 recirculates the air through the accumulator 48, the normally open compressed air control valve 50 and back to the compressed air outlet 16. The backpressure controller 54 helps control the pressure of the compressed air stream through the nozzle 16 and draws excess air to the exhaust pipe 57. The compressed air stream control valve 50 receives control signals along line 50A from the microprocessor controller 34, typically to maintain the valve open to allow air to flow to the nozzle.

 Electric power is supplied to the pump 46 via line 46A connected to the output of the (automatic) switch 76, which, in turn, is connected to the output of the AC filter 74 and the AC power source PS.

 The detection device 27 in the embodiment shown in FIG. 2 is an analyzer that detects residues of selected compounds, for example nitrogen-containing compounds, in control tanks using the chemiluminescence method. This type of detection device is generally known and includes a chamber for mixing ozone with nitric oxide or with other compounds that interact with ozone to allow them to interact, a radiation transmitting element (with an appropriate filter) and a radiation detection device for detecting chemiluminescence from reaction products. For example, when NO obtained from heating nitrogen compounds (e.g., ammonia) in the presence of an oxidizing agent (e.g., air oxygen) chemically interacts with ozone at given wavelengths, e.g., wavelengths in the range of about 0.6 - 2.8 μm, a characteristic light emission. Selected portions of this chemiluminescence radiation and its intensity can be detected using photoelectronic multipliers.

Accordingly, in the system shown in FIG. 2, ambient air is drawn into the ozone generator 64 through the inlet 60 and the air filter 62. There, ozone is generated by an electric discharge in the air and released through the ozone filter 66 and the flow regulator 68 into the detection device 27, in which it mixes with samples from containers introduced through the supply pipe 20, a filter 40, a flow restrictor 42 and a transducer 54. A sample from the supply pipe 20 is passed through a transducer 44, for example an electrically heated nickel tube, in which the temperature rises to approximately 800 - 900 ^o C before entering into the detection device 27. Temperatures in the range 400-1400 ^° C may also be acceptable. When nitrogen-containing compounds, for example ammonia, are heated, NO (nitric oxide) is thus obtained, and this nitric oxide is fed into the chamber of the detection device 27. Compounds other than NO, which can react with chemiluminescent O ₃ and can also be produced in converter 44, for example, organic compounds obtained by heating gasoline or purifier residues.

 The temperature controller 70, the electric power to which is supplied through the transformer 72, is used to control the temperature of the converter 44.

 Samples in the detection device 27, after passing through its chamber, are discharged through the accumulator 85 and the pump 82 into the ozone cleaner 56 and the outlet of the exhaust pipe 57 to clear the detection device of residues for the next sample from the next tank moving along the conveyor 10 in FIG. 1 (to help clean up any residual sample cloud near the sample inlet pipe 20, a (optional) fan, not shown in FIG. 2, may be used, as shown above. The output from the detection device 27 related to the monitoring results is output through a preamplifier 84 to the microprocessor 34, which accordingly transmits this information to the recording device 83. The recording device 83 is preferably a conventional tape recording device or the like, which displays the signal amplitude depending from the time of the analyzed sample.

 The microprocessor 34 can be programmed to recognize (as a "burst" or detection of specific residues) a burst of signal from the photodetector of the detection device 27, which is presented in a predetermined time interval (based on the detected receipt of the capacitance in the installation for monitoring) and whose slope and amplitude reach the specified values that are then maintained for a given holding period.

 The microprocessor controller 34 also has an outlet to the bottle ejector 28 for rejecting contaminated bottles and separating them from bottles heading to the washer.

 A calibration terminal 86 is provided for residual analyzer 26 to control the high voltage source 26A associated with the detection device. An input terminal of a power divider of the recording device 88 is also provided, connected to the microprocessor controller 34 to control the operation of the recording device. The detection device 27 receives electric power from a high voltage source 26A.

 Additional control devices include an operator panel 90 comprising a keyboard and a display allowing the operator to appropriately control the operation of the detection device 27.

 DC power is applied to all relevant components through a DC power source 78 connected to the output of the PS power source.

 An optional 80A alarm is provided to alert the operator of contaminated containers. An alarm 80A is connected to the output of the microprocessor controller 34 via an output control line 80C. The fault signal 80B is also connected to the microprocessor controller 34 for receiving fault or fault signals, for example, from a membrane switch 58 or a vacuum switch 87 when the pressures are outside certain predetermined limits.

 Other safety devices, such as a vacuum gauge 89 and a back pressure regulator 54, may be provided to ensure proper operation of the system.

 Most of the components of the entire system shown in FIG. 2 are preferably enclosed in a rust-proof stainless steel casing 92. The casing is a cooled counterflow heat exchanger 92 having hermetically separable sections 91A and 91B, in which the counterflow of air is provided by suitable fans.

 As described above, the system of FIG. 2 in a preferred embodiment is used to detect the presence of nitrogen-containing compounds in a sample, for example, from a refillable beverage bottle. However, it would be desirable to use the system of FIG. 2 to detect the largest possible range of contaminants, including potential contaminants that would chemiluminesce in the region of the radiation spectrum, which may overlap with the chemiluminescence of the beverage ingredients (below the “product”) that was packaged in the beverage bottle.

 This is carried out in accordance with the present invention using the method partially illustrated in FIG. 3 and described below.

From FIG. 3, which is a graph of the dependence of the radiation signal intensity (ordinate axis, in millivolts) on the wavelength (abscissa axis, in microns) emitted by chemiluminescence, it can be seen that the radiation emitted by the chemiluminescence of nitrogen-containing compounds (reaction NO + O ₃ ) is in in the range of about 0.6 to 2.8 microns (near infrared). Therefore, when using the system of FIG. 2 and its detection device 27 to detect only nitrogen-containing compounds, a filter with a limited passband 100 is used to block all chemiluminescence radiation from the sample at wavelengths below about 1 μm from reaching the photomultiplier detector of the detection device 27. This is desirable if the detection of nitrogen-containing compounds is a priority, since chemiluminescent radiation emitted below 1 μm (visible light, close to infrared) is potentially emitted by the residues of the “product” in the samples extracted from the refill bottles from the beverage bottle. Consequently, a single-micron filter with a limited passband 100 eliminates false rejection signals that may be caused by high levels of product residues in the controlled bottle. Of course, it is very important to eliminate or minimize false rejection signals to minimize the loss of refillable bottles.

 However, it is a discovery of the present invention that if a beverage bottle is stored in an unclosed state, that is, with its upper part unclosed, for a sufficient time to be monitored by the system of FIG. 2, the volatiles of the residues of the “product” are sufficiently dispersed from the bottle, so that they are not detectable under sufficient conditions to cause false rejection signals. That is, if a single-micron filter 100 is removed and replaced with a quartz filter with a limited passband having a limited passband of 0.19 μm, the volatiles of the “product” will not exist in large enough quantities to generate reject signals if the bottles were stored unopened in for a sufficient period of time. This time period will vary for different “products”. However, a storage period of approximately 15 hours for an unclosed bottle gave good results in the tests performed. These results are summarized in a table for samples recovered by a pump from beverage bottles containing a wide range of contaminants and product residues.

 Column 1 of the table at the top lists "samples" including potential contaminants in beverage bottles that are detectable by the method and system of the present invention. These contaminants are detectable in addition to nitrogen-containing compounds. The designation "unclosed" means that the bottles containing the remainder were stored for a specified time with their upper hole not closed, the absence of symbols indicates that contamination was present and the upper hole was opened for only a short time before the test.

 The "samples" at the bottom of column 1 include examples of tested drinks and indications of closed bottles or unclosed and, if unclosed, this means a period of storage of the remaining bottle with its open hole for, for example, 15 hours. The designation “closed” means that the bottle was tested with the remaining beverage and the top opening was open for only a short period of time before the test. “Fresh” means that the bottle was tested shortly after it was opened and contained the fresh product in liquid form, that is, essentially a full bottle of the drink, and not the old fermented product.

 Column 2 of the table shows the intensity in millivolts of the signals measured with the photomultiplier tube in the detection device 27 with a quartz filter 102 with a limited passband of 0.19 μm at the input window of the photomultiplier tube 104. It can be seen that signals of significantly different levels exist for these contaminants closed or unclosed bottles for drinks.

 The data in column 2 also shows that for “unclosed” beverage bottles stored for 15 hours, the volatiles of the “products” are undetectable (0 millivolts) using a photomultiplier tube 104.

 Column 4 of the table shows the test results of the system, which includes a single-micron filter 100, and the levels of detected signals in millivolts for various contaminants or products of column 1. It can be seen that essentially all the useful signal data related to the contaminants in the table are lost when using a single micron filter 100.

 Column 3 of the table shows the results obtained with a filter 106 with a limited passband of 0.4 μm installed at the input of the photomultiplier tube 104 instead of any of the filters 100 or 102. It can be seen that when using a filter 106 with a limited passband of 0.4 μm, detectable are some useful pollution data.

 Therefore, the discovery of the present invention that storing beverage bottles in an unclosed state eliminates the possibility of generating false signals of rejecting the “product” from the volatiles, is the most significant and useful discovery. That is, the method of the present invention, which encompasses the concept of storing unclosed beverage bottles for sufficient time to allow the volatility of the “product” to disperse, allows the detection of a wide range of other contaminants, such as those listed in the above table, in addition to contaminants including nitrogen-containing compounds.

 Obviously, the invention described in this way can be modified in many different ways. For example, other types of high speed analyzers, such as electron capture detectors or photoionization detectors, may be acceptable, instead of the chemiluminescent analyzer described with reference to FIG. 2.

 A sample drawn into conduit 20 can also be divided into two or more streams and introduced into a plurality of analyzers 26. Therefore, each analyzer 26 can be used to detect various types of contaminants.

 In addition, controlled materials are not limited to substances in containers. For example, the method and system of the present invention can be used to detect volatile substances adsorbed by cut strips or flakes of resin or plastic raw materials recycled to produce new plastic beverage bottles. This chopped or flaked plastic raw material can be directly placed on the conveyor belt 10 and passed through the inspection apparatus 12 shown in FIG. 1, or plastic raw materials can be placed in baskets, buckets or other types of containers placed on the conveyor and controlled in batches.

 Other controlled bottles may be new bottles that have never been filled with a drink. Thus, new bottles can be controlled for excessive acid aldehydes, which can be co-products of the manufacturing process.

 Such changes should not be construed as deviating from the essence and scope of the present invention and all such modifications, as will be apparent to those skilled in the art, will be included in the scope of the following claims.
