    WO 2013/130348 PCT/US2013/027315 1 APPARATUS AND METHOD FOR DETECTING LEAKAGE FROM A COMPOSITION CONTAINING POUCH FIELD OF THE INVENTION 5 This disclosure relates to a machine vision method for detecting leakage from a composition-containing pouch during the manufacturing process and an apparatus used therefore. BACKGROUND OF THE INVENTION Consumer products are manufactured on high-speed production lines. A production line 10 typically includes a series of steps or stations at which different portions of the consumer product are made and/or modified. These steps are often accomplished at the highest possible speed, so as to achieve a high output and low production costs. Yet it is still desirable to maintain the required quality standards for the consumer product. As such, high-speed production lines typically include a means of inspecting the completed consumer product(s). 15 Manual or digital inspection of every single product at the end of a high-speed production line may be inefficient for a number of reasons. First, it is time consuming to inspect each and every consumer product that comes off of a high-speed production line. Indeed, it oftentimes is simply impractical. One solution to this problem is to manually or digitally inspect a sampling of the consumer product. However, use of this approach ultimately may mean that that some faulty 20 consumer products escape the inspection process and/or faulty products are not identified until it is too late to correct outages along the production line. This can result in whole batches of faulty consumer products, which may not be marketable "as is." Consumer products made along high-speed production lines include pouches that are used to package household care compositions such as laundry or dish detergent. The current pouches 25 on the market include single compartment pouches as well as multi-compartment pouches, which are collectively referred to herein as "unit dose pouches." The compartments are manufactured along high-speed production lines using platens comprising a series of mold cavities into which water-soluble film is drawn and is deformed such that it takes the cavity's shape. The resulting compartments may then be sealed to form a single-compartment pouch or at least a portion of a 30 multi-compartment pouch. In this way, multiple unit dose pouches are made simultaneously. If at least one of those unit dose pouches is defective, the composition may leak, causing contamination of the production line and/or other unit dose pouches. SUMMARY OF THE INVENTION WO 2013/130348 PCT/US2013/027315 2 There remains a need for an efficient, fast and thorough method and apparatus for inspecting unit dose pouches for quality assurance as they are being made along a high-speed production line. The present disclosure addresses the aforementioned need by providing a converter-integrated machine apparatus and a method for monitoring the quality of unit dose 5 pouches. A new apparatus for detecting leakage from a composition-containing pouch during the high-speed manufacturing process is described herein. The apparatus comprises: a platen comprising a pouch cavity and a plurality of platen edges adjacent to the cavity; an imaging unit; an image processing unit; and an actinic radiation emitting source. The actinic radiation emitting 10 source may be an ultra violet light. The actinic radiation-emitting source is arranged to expose at least one of the plurality of platen edges with actinic radiation. The imaging unit is arranged to obtain an image of the at least one of the plurality of platen edges exposed to the actinic radiation. The imaging unit is communicably attached to the image processing unit. A new method for detecting leakage from a composition-containing pouch is described 15 herein. The method may be performed along a production line one or more times. The composition-containing pouch is located in the cavity of a platen disposed in a pouch converting line. The composition comprises a photoactive compound that is responsive to actinic radiation. The platen has a plurality of platen edges adjacent to the cavity. The method comprises the following steps. At least one of the plurality of platen edges is exposed to the actinic radiation 20 emitting source. An image of the at least one of the plurality of platen edges exposed to actinic radiation is obtained. Actinic radiation emitted from the photoactive compound, if present on the at least one of the plurality of platen edges, is detected. If actinic radiation emission is detected, a fail message is sent to a controller such as a programmable converter ("PLC") or programmable automation controller ("PAC"). Optionally, the controller may then direct the leaky pouch 25 and/or pouch(es) located in an adjacent cavity or cavities to be ejected from the converting line.

Copies of this patent or patent application publication with color drawings will be provided by the office upon request and payment of the necessary fee. 15 DETAILED DESCRIPTION OF THE INVENTION "Comprising" as used herein means that various components, ingredients or steps can that be conjointly employed in practicing the present disclosure. Accordingly, the term "comprising" encompasses the more restrictive terms "consisting essentially of' and "consisting of'. The present compositions can comprise, consist essentially of, or consist of any of the required and 20 optional elements disclosed herein. Manufacturing Process Unit dose pouches are made using suitable equipment and methods. For example, unit dose pouches are made using vertical form filling, horizontal form filling, and/or rotary drum filling techniques commonly known in the art. Such processes may be either continuous or 25 intermittent. Examples of continuous in-line processes of manufacturing water-soluble containers are set forth in U.S. 7,125,828, U.S. 2009/0199877A1, EP 2380965, EP 2380966, U.S. 7,127,874 and US2007/0241022 (all to Procter & Gamble Company, Ohio, USA). Examples of non-continuous in-line processes of manufacturing water-soluble containers are set forth in U.S. 7,797,912 (to Reckitt Benckiser, Berkshire, GB). Each of these processes may utilize a platen 30 comprising a plurality of mold cavities. Generally, the process may comprise the following steps. A film is heated and/or wetted and fed onto the surface of the platen. Once on the surface of the platen, the film can be held in position by any means. For example, the film can be held in position through the application of WO 2013/130348 PCT/US2013/027315 4 vacuum on the film, thus pulling the film in a fixed position on the surface. The vacuum may be applied along the edges of the film and/or on the surface area between the mold cavities. The platen surface may have at least some holes connected to a unit which can provide a vacuum as is known in the art. 5 Any film that is suitable for making a unit dose pouch is used. Non-limiting examples of water-soluble films that are used include those comprising polyvinyl alcohol as described in: U.S. 2011/0204087Aland U.S. 2011/0188784A1 (each to Procter & Gamble Company, Ohio, USA). Further non-limiting examples include commercially available films including: M8630 and M8900 supplied by MonoSol (Gary, Indiana, USA) and/or films known under trade 10 reference Solublon@ of films supplied by Aicello (North Vancouver, BC, Canada) or Poval film supplied by Kuraray (Houston, Texas, USA). Once open pockets of film are formed into the mold cavities, they may be filled with composition and sealed by any known method, including those described in the patent publications listed above. The sealing step typically is accomplished by sealing a second water 15 soluble film to the open top of the pocket. In some embodiments, the second water-soluble film may itself form a portion of one or more composition containing pockets. Non-limiting filling and sealing means are described in U.S. 6,995,126, U.S. 7,125,828, U.S. 2009/0199877A1, EP 2380965, EP 2380966, U.S. 7,127,874 and US2007/0241022 (all to Procter & Gamble Company, Ohio, USA). 20 Composition The unit dose pouches may contain any composition that is suitable for an intended us. Non-limiting examples of useful compositions include light duty and heavy duty liquid detergent compositions, hard surface cleaning compositions, detergent gels commonly used for laundry, and bleach and laundry additives, shampoos, body washes, and other personal care compositions. 25 The compositions may take the form of a liquid, gel, solid or a powder. Liquid and gel compositions may comprise a solid. Solids may include powder or agglomerates, such as micro capsules, beads, noodles or one or more pearlized balls or mixtures thereof. Compositions useful in the present disclosure comprise a photosensitive compound. When exposed to an actinic radiation source, the photosensitive compound emits actinic 30 radiation. Photosensitive compounds of use in the present invention include fluorescent dyes, ultraviolet dyes, near infrared dyes and infrared dyes, such as those that are used as optical brighteners, i.e., compounds that tint laundry articles. Optical brighteners which may be useful in the present invention can be classified into subgroups, which include, but are not necessarily WO 2013/130348 PCT/US2013/027315 5 limited to, derivatives of stilbene, pyrazoline, coumarin, carboxylic acid, methinecyanines, dibenzothiophene-5,5-dioxide, azoles, 5- and 6-membered-ring heterocycles, and other miscellaneous compounds. Examples of such brighteners are disclosed in "The Production and Application of Fluorescent Brightening Agents", M. Zahradnik, Published by John Wiley & 5 Sons, New York (1982). Non-limiting examples of optical brighteners which are useful in the present compositions are those identified in U.S. Pat. No. 4,790,856 and U.S. Pat. No. 3,646,015. Non-limiting examples of stillbene derivatives of use include the following. Colour Index ("C.I.") fluorescent brightener 260 in predominantly the alpha-crystalline form and having the following structure: 10 (I) "Predominantly in alpha-crystalline form," means that typically at least 50wt%, at least 75wt%, at least 90wt%, at least 99wt%, or even substantially all, of the C.I. fluorescent brightener 260 is 15 in alpha-crystalline form. This brightener is typically in micronized particulate form, having a weight average primary particle size of from 3 to 30 micrometers, from 3 micrometers to 20 micrometers, or from 3 to 10 micrometers. The composition may comprise C.I. fluorescent brightener 260 in beta-crystalline form, and the weight ratio of: (i) C.I. fluorescent brightener 260 in alpha-crystalline form, to (ii) C.I. fluorescent brightener 260 in beta-crystalline form may be at 20 least 0.1, or at least 0.6. BE680847 relates to a process for making C.J fluorescent brightener 260 in alpha-crystalline form. A further stilbene derivative of use has the structure below: WO 2013/130348 PCT/US2013/027315 6 63| N NN (II). Suitable fluorescent brightener levels include lower levels of from about 0.01, from about 0.05, from about 0.1 or even from about 0.2 wt % to upper levels of 0.5 or even 0.75 wt %. Further stilbene derivatives of use include 2,2'-(1 ,2-ethenediyl)bis [ 5-[ [4,6 5 bis(phenylamino)-1,3,5-triazin-2-yl]amino]benzenesulfonic acid, and 4,4'-BIS(2-DISULFONIC ACID STYRYL) BIPHENYL, which is also known as C.I. Fluorescent Brightener 351.One of skill in the art may determine the minimum and maximum amount of actinic radiation emitting compound to use based upon the desired level of actinic radiation emission. Often this consideration is balanced against the cost and/or usefulness of the compound in the composition 10 as well as the sensitivity of the image unit utilized to detect the actinic radiation emitting compound. In one example, useful concentrations of fluorescent whitening compound are from about 50 parts per million ("ppm") to about 2500 ppm, from about 100 ppm to about 2000 ppm, and from about 200 ppm to about 1500 ppm. 15 Platen Typical unit dose manufacturing lines utilize a surface containing the mold cavity for each compartment that forms the unit dose pouch. Often, the surface is removably connected to a moving, rotating belt, for example a conveyer belt or platen conveyer belt. The movement of the belt may be continuous or intermittent. The surface can be removed as needed and replaced with 20 another surface having other dimensions or comprising moulds of a different shape or dimension. This allows the equipment to be cleaned easily and to be used for the production of different types of unit dose pouches. Any useful surface may be used. Referring now to Fig. 1, one embodiment of a platen 10 of use is shown. In Fig. 1, a plurality of mold cavities 100 are present in a 2-D array on the surface of the platen 10. In this 25 embodiment there are 12 mold cavities in the machine direction of the platen and 7 mold cavities in the cross-machine direction. Each cavity may be defined by a Row, "R," in the machine WO 2013/130348 PCT/US2013/027315 7 direction and a Lane, "L," in the cross machine direction. It follows that since there is a plurality of mold cavities on the surface of the platen that each cavity has at least three neighboring cavities except for those mold cavities directly adjacent to the four edges of the platen itself 120. For example cavity 101 in Fig. 1 has four neighboring cavities, 102, 103, 104 and 105, whereas 5 cavity 105, which is on the edge of the platen itself 120, has only three neighboring cavities 101, 106 and 107. Between the cavity 101 and each of its four neighboring cavities are platen edges 12 adjacent to the cavity. Fig. 2 depicts another useful embodiment of a platen 10. The mold cavities 100 are located on the curved surface of a drum 11. Like the platen described above, there are a plurality 10 of mold cavities on the surface of the drum, such that each cavity has at least two neighboring cavities. Unit Dose Pouches Single or multi-compartment pouches may be made utilizing the mold cavities such as those described above. Non-limiting examples of single compartment pouches and methods of 15 making them are those that are presently on the market under the names Tide Pods, All Mighty Pacs, Purex Ultra Packs, Persil, OMO Pods, Tesco Capsules, Arm & Hammer Crystal Power Pacs. Non-limiting examples of multi-compartment pouches and methods of making unit dose pouches are described in U.S. 2010/0192986A1, U.S. 6,995,126, U.S. 7,125,828, U.S. 7,127,874, U.S. 7,964,549, U.S. 2009/0199877A1, U.S. 6,881,713, U.S. 7,013,623, U.S. 7,528,099, and U.S. 6,727,215 20 (each to the Procter & Gamble Company, Ohio, USA). Tide Pods and Ariel Pods are examples of multi compartment pouches that are currently on the market. Actinic Radiation-Emitting Source Any suitable actinic radiation emitting source may be utilized to cause the photoactive compound(s) in the composition to emit actinic radiation. Non-limiting examples of suitable actinic radiation emitting sources include: an ultraviolet light; a white light; a near infra red light; an infra red light; and combinations thereof. Imaging Unit The inspection of the unit dose pouch and/or the at least one of the platen edges adjacent 25 to the cavity in which the unit dose pouch is located can be accomplished using any suitable camera or other optical picture-capturing device. Non-limiting examples of cameras of use include a line scan camera such as the In-Sight 5604 Camera from Cognex (Natick, MA, USA), one of the PC line of cameras from Teledyne Dalsa (Billerica, MA, USA), the Elixa UC8 or one of the Aviiva line of cameras from e2v (Tarrytown, NY, USA), or the spL8192-39k or spL4096 30 70 k from Basler AG (Ahrensburg, Germany).
    WO 2013/130348 PCT/US2013/027315 8 Image Processing Unit The image processing unit may be a stand-alone unit or it may be an integral part of the camera. One non-limiting example of an integrated camera and image processing unit is the In Sight 5604 Camera from Cognex (Natick, MA, USA). The image processing unit inspects the 5 image captured by the camera to look for actinic radiation being emitted from at least one of the platen edges surrounding the composition-containing pouch. If actinic radiation is detected on a platen edge, then the image processing unit sends a fail message to the controller. In one embodiment, the image processing unit integrates the captured image and executes a programmed process to analyze the image. Based upon the results of the image analysis, a pass 10 or fail decision is communicated to the controller. Controller A programmable controller is utilized. A suitable controller is selected from a programmable automation controller or a programmable logic controller. A useful programmable automation controller may be selected from the Control Logic family of 15 programmable automatic controllers from Rockwell Automation (Anaheim, CA, USA). Examples A unit dose pouch 2000 comprising three compartments as shown in Fig. 3 is present in a cavity of a platen after being sealed. The compartments each contain 50 parts per million of C.I. Fluorescent Brightener 351. A vision apparatus according to the present disclosure is mounted 20 in-line with the unit dose pouch production line after the stage at which the three compartments are sealed to each other. Fig. 4 shows a block diagram of a vision apparatus 1000 according to the present disclosure. A series of Cognex In-Sight 5604 line scan vision cameras 1100 are positioned above the platen 10 and span the platen in the cross machine direction. The camera utilizes a CCD chip 25 (imager), which consists of a single row of pixels. The single row of pixels is captured repeatedly in real time synchronized with the motion of the speed of the converter. In this way, an image of each cavity in the platen and the edges adjacent to the cavity is captured. The camera software assembles the individual rows of pixels into a single area image. An ultraviolet light-emitting diode line light ("UV light") 120 is mounted and directed at 30 the pouch platen 10 to line up with the camera focal center lines for lighting the cavities to be inspected by the cameras. When the converter motion begins, the UV light 120 is powered on by the programmable automation controller ("PAC") 1200. When powered on, the UV light 120 emits actinic radiation that excites the C.I. Fluorescent Brightener 35 located in the pouch and, if WO 2013/130348 PCT/US2013/027315 9 present, on the platen edges surrounding the pouch. The cameras are triggered simultaneously by an output from the line's PAC that communicates with the cameras via an Ethernet switch. After an image of the pouches and platen edges surrounding the pouches is captured and integrated into a single bitmap, the cameras execute the programmed process to analyze the 5 image. At the same time that this image is analyzed, another trigger input from the PAC signals the cameras to begin capturing data for the next-in-line pouches and the platen edges surrounding those pouches. A pass/fail decision is evaluated for each pouch location on the converter platen. The pass/fail decision is communicated to the PAC via an Ethernet switch. Each row and lane is 10 determined to pass or fail if it contains a leaker. Fig. 5 shows an image captured by one of the four cameras. In this embodiment, the camera is precisely aligned across the platen in the cross machine direction to line up with three pouches 2000 located in the pouch cavities and platen edges 12 adjacent to the cavities; the cavities themselves are not visible in Fig. 5 due to the presence of the pouches 2000 in the 15 cavities. In this embodiment, the camera has reference regions shown as the light blue box 200 in alignment with the sides of the actual outer boundaries of the platen edges 12 surrounding each cavity. In Fig. 5, no actinic radiation is detected on any of the platen edges 12, thus no leak is detected. The camera communicates a "pass" status for this row of pouches over an Ethernet IP 20 protocol to the PAC. Fig. 6 shows a row of pouches 2000 and associated platen edges 12. Actinic radiation 150 is detected on the platen edge 12 to the right of the pouch 2000 on the far right. Thus a leak is detected on the right platen edge 12 of this pouch. The camera communicates a "fail" status of this row over the Ethernet IP protocol to the PAC. The PAC then directs that leaky pouch and its 25 neighbor to be ejected from the converting line. The dimensions and values disclosed herein are not to be understood as being strictly limited to the exact numerical values recited. Instead, unless otherwise specified, each such dimension is intended to mean both the recited value and a functionally equivalent range surrounding that value. For example, a dimension disclosed as "40 mm" is intended to mean 30 "about 40 mm."
