    lO TITLE: AN ASSEMBLY FOR WASTE COLLECTION TECHNICAL FIELDThe present technology generally concerns the managing of waste and in particular relates to means for collection, temporary storage and disposal of waste of various kinds in association with deposit points of a pneumatic material collection and transport system.
    BACKGROUND Vacuum operated Waste collection systems are presently used in many parts of the world andare employed for managing different fractions of waste and refuse. In such systems, waste hastraditionally been introduced into the system at fixed insertion points. Normally, said insertionpoints have some type of integrated temporary waste storage facility in order to provide betterwaste discharge control. The insertion points or their temporary waste storage facilities areconnected through a waste transport pipe system to a stationary central waste collection facili- ty with a likewise stationary vacuum source.
    A development of the above briefly described “stationary type” vacuum operated wastecollection system involves the use of movable vacuum sources mounted on trucks having awaste tank of considerable volume. The vacuum pressure generated by the movable vacuumsources is selectively connected to docking points positioned in the vicinity of one or moretemporary waste storage tanks. The tank or tanks are in tum connected through dischargepipes to associated docking points and a major advantage of these “mobile type” vacuumoperated waste collection systems is that they do not require any extended transport pipesystems connecting insertion points or their temporary waste storage facilities with the central waste collection facility.
    Both of the above described types of vacuum operated waste collection system variants haveserved their intended purpose well. However, both variants lack an extended versatility thatwould be beneficial also in areas of waste collection other than in residential and office en- vironments.
    SUMMARY It is a general object of the present technology to improve the versatility of a pneumatic material collection and transport system. 2 In particular it is an object of the technology to suggest an improved waste managing assembly for use in association with a pneumatic material collection and transport system.
    These and other objects are met by the technology as defined by the accompanying claims. lhe present technology relates generally to a waste managing assembly forthe collection, storage and discharge of waste by a pneumatic material collection and transportsystem. The system uses air flow through a pipe to transport collected material from a Waste tank at one or more waste deposit and discharge points of the system. lhe Waste managing assembly includes a bottom waste storage and discharge tank sectionwith a base for supporting the waste managing assembly at a waste deposit and dischargepoint, a relocatable top waste receiving tank section having at least one waste introductionopening for introducing waste into the top waste receiving tank section, an interface fordocking a lower part of the top waste receiving tank section on an open upper part of thebottom waste storage and discharge tank section; and bottom walls at the lower part of the topwaste receiving tank section and operable to open and close communication of waste betweenthe top and bottom tank sections of the waste managing assembly. ln a basic configurationarcuate guide grooves are formed in end walls of each top waste receiving tank section, thebottom walls at the lower part of each top waste receiving tank section are swingably andslidably supported in the guide grooves in the opposite end walls of each top waste receivingtank section and are provided with guide members that externally of the associated end wallcooperate with a first pair of guide formations of a docking adapter in the interface as well aswith the guide grooves to control operation of the bottom walls between a closed positionblocking a waste communication between the lower part of a top waste receiving tank section and the bottom waste storage and discharge tank section and an open emptying position opening said communicatiom Preferred further developrnents of the basic technology as well as embodiments thereof are specified in the dependent subclairns.

The embodiments serve to exemplify the use of the principles of thenew technology in an application for managing waste material in association with a pneumaticmaterial collection and transport system using vacuum or suction air flow through a wastetransport pipe to discharge the Waste material. lt shall be emphasized that the illustrationsserve the purpose of describing preferred embodiments of the technology and are not intended to limit the technology to details or to any specific field of application thereof.
    To overcome shortcomings and problems normally encountered within this technical field andbriefly discussed in the introduction, the present technology now suggests a novel approachfor optimizing the versatility of a pneumatic waste material collection and transport system.This is done by providing a Waste managing assembly for independent collection and tempo-rary storage and then discharge of waste in association with a pneumatic material collectionand transport system. More specifically, the waste managing assembly proposed by thepresent technology may also be defined as a composite waste material container or tankincluding mutually docking upper and lower container/tank sections. Thereby it enables theuse of a quite unique two-stage waste collection approach where the two tank sections may be located at separate appropriate locations and may at intervals be docked for waste discharge.
    The tank/container will throughout the rest of the specification be referred to as a tank, but itwill be clear that it may take the form of any appropriate container. lt is preferably a so calledscrew tank type having a feed screw provided adjacent a bottom section of the tank for en-abling quick and secure waste discharge from the assembly. By combining a bottom dischargetank section with an optional number of separate relocatable top waste receiving temporarystorage tank sections said assembly enables optimized and problem-free collection of wastefrom several locations. With the suggested new technology this is in essence achieved by de-centralizing the collection of larger amounts of waste without requiring any additional fixedor stationary installations, apart from the single bottom assembly tank section. This unique design of the proposed configuration provides several essential advantages that will especially 5 present solutions to problems existing in areas such as in the hospital sector, by commercial properties, larger construction sites etc.
    Fig. l illustrates an exemplary embodiment of the general application of the proposed techno-logy to a waste managing assembly 1. The waste managing assembly l is intended for thecollection, temporary storage and discharge of waste in association with pneumatic materialcollection and transport systems 100. Such systems use air flow through a Waste transportpipe 101 to transport collected waste material from a waste tank 2, 4 at one or more wastedeposit and discharge points 102 of the pneumatic material collection and transport system.The waste tank 2, 4 of each waste managing assembly 1 basically includes a bottom wastestorage and discharge tank section 2 and at least one relocatable top waste receiving tanksection 4 associated therewith. In embodiments where the assembly 1 includes more than onetop waste receiving tank section 4 these are, apart from being relocatable, also mutually ex-changeable, meaning that they may all be connected to the same or to different bottom wastestorage and discharge tank sections 2. The bottom waste storage and discharge tank section 2is stationary at a designated waste deposit and discharge point 102 of the pneumatic materialcollection and transport system 100. Thus, one or more relocatable top waste receiving tanksections 4 may be associated with each stationary bottom waste storage and discharge tanksection 2 and may be located at a designated, later described waste introduction point 103 forreceiving waste. The bottom waste storage and discharge tank section 2 has a base 3 with anumber of support legs 3A for supporting the bottom waste storage and discharge tank section2 at a waste deposit and discharge point 102 from Where collected waste is discharged byvacuurn pressure to any type of waste collection facility, such as a stationary type centralstorage or a mobile type storage (not specifically shown). This waste discharge is performedfrom a tapered outlet section 2A of the bottom waste storage and discharge tank section 2,through a controlled discharge valve DV and then to said waste transport pipe 101 of a pneumatic material collection and transport system 100, as schematically indicated in F ig. 1.
    The relocatable top waste receiving tank section 4 has at least one waste introduction opening5 for introducing waste into said top waste receiving tank section at appropriate waste intro-duction points or waste receiving locations 103 of a waste collection application. At the sideor sides thereof that contain the at least one waste introduction opening 5 the top wastereceiving tank section 4 is also preferably provided with a step or platform 25 for facilitating the introduction of waste. The top waste receiving tank section 4 also has a base 6 including a 6 number of support legs 6A for independent placement thereof at a waste introduction point103 where waste is to be introduced into it. The support legs 6A are separated so as to bepositioned outside a later described interface 7 as well as outside the bottom waste storage anddischarge tank section 2 when docking the lower part 10 of the top waste receiving tanksection 4 on the open upper part 9 of the bottom waste storage and discharge tank section 2.The top waste receiving tank section 4 may be lowered onto and lifted from the bottom wastestorage and discharge tank section 2 by means of a truck mounted crane (not specificallyshown) or other lifting equipment that is hooked to a lifting eye 17 in a lifting beam 16provided on an upper part of the top waste receiving tank section 4. Alternatively a number oflifiing eye bolts 17”, secured to and distributed on the upper part of the top waste receiving tank section (as indicated in Fig. 2), could be used as lifting means. ln practical use of the waste managing assembly 1 the bottom waste storage and dischargetank section 2 of the waste tank 2, 4 is located at its designated waste deposit and dischargepoint 102 and the top waste receiving tank section 4 is relocatable between waste introductionpoints 103 and a waste deposit and discharge point 102. The bottom waste storage and dis-charge tank section 2 has the above briefly mentioned open upper part 9 and an interface 7 fordocking a lower part 10 of the top waste receiving tank section 4 on said open upper part 9 ofthe bottom waste storage and discharge tank section 2. Bottom walls 11A, 11B (see especiallyFigs. SA-SB) are provided at the lower part 10 of the top waste receiving tank section 4 andare operable to selectively open and close communication of waste between said top andbottom tank sections 4 and 2, respectively, of the waste managing assembly 1. The bottomwalls 11A, 11B are movably supported in opposite end walls 4A, 4B of the top waste receiving tank section 4 and are extended along opposite sides of said lower part 10 thereof.
    To enable selective release of introduced waste from the top waste receiving tank section 4the bottom walls 11A, 11B are each associated with a support assembly 18 that in cooperationwith the interface 7 automatically initiates a swinging-sliding movement of the bottom walls11A, 11B between open and closed positions II and I, respectively. This automatic openingand closing movement of the bottom walls 11A, 11B is caused by interactive cooperation ofparts of the bottom wall 11A, 11B support assemblies 18 and the interface 7 as the top wastereceiving tank section 4 is lowered onto and lifted from, respectively, the bottom waste stor- age and discharge tank section 2, as will be described in detail below. 7 The interface 7 includes a docking adapter 8 (see Figs 6A-6B) fixed to the open upper part 9of the bottom Waste storage and discharge tank section 2. The docking adapter 8 has first 8A,8B and second 8D, 8E pairs of guide forrnations controlling operation of the bottom walls11A, 11B at the top waste receiving tank section 4 between open Il and closed I positions andback. As mentioned above, the bottom walls 11A, 11B of the top waste receiving tank section4 are swingably-slidably supported in opposite end walls 4A, 4B of the top waste receivingtank section 4. In the respective end faces of the bottom Walls 11A, 11B are provided guidemembers 20A, 20B of the support assemblies 18. The guide members 20A, 20B extend fromthe respective end faces of the bottom walls 11A, 11B, through arcuate guide grooves 12, 13 formed in associated end walls 4A, 4B of the top waste receiving tank section 4.
    Extending externally of the associated end wall 4A, 4B the guide members 20A, 20B co-operate with a first pair 8A, SB of docking adapter 8 guide formations as well as with saidguide grooves 12, 13 to control bottom wall 11A, 11B operation. This operation of the bottomwalls 11A, 11B involves their movement between the closed position I blocking an otherwiseopen Waste communication between the top waste receiving tank section 4 and the bottomwaste storage and discharge tank section 2 and the open emptying position II opening saidcommunication. The bottom walls 11A, 11B are thus guided in the guide grooves 12, 13 inthe swinging-sliding movement between the open Il and closed I positions. Specifically, theguide grooves 12, 13 each accommodate a guide member 20A, 20B of the bottom walls 11A,11B for guiding their Swinging and sliding movement between the closed waste blockingposition I and the open emptying position II. In order to secure smooth and undisturbedmovement of the bottom walls 11A, 11B each of them is also provided with a guide block 26at the end faces thereof, spaced from the associated guide member 20A, 20B, as well as adistributed set of slide rails 27. Said slide rails 27 are secured to an outer, curved side of the bottom walls 11A, 11B, facing a side wall of the top waste receiving tank section 4.
    The support assemblies 18 further include a pair of locking arms 18A, 18B (see especiallyFig. 4) that are pivotally supported in the end walls 4A, 4B. The looking arms 18A, 18B areprovided with a hook-shaped outer free end that in the closed position I of the bottom walls11A, 11B is pivoted down to grip a free end of an associated guide member 20A, 20B. Thisserves to maintain the bottom walls 11A, 11B in a closed and locked position I blockingwaste communication between the lower part 10 of the top waste receiving tank section 4 and the bottom waste storage and discharge tank section 2. Adjacent the hook-shaped outer free 8 end each locking arm 18A, 18B carries a guide pin 19A, 19B that in use cooperates with anassociated one of a pair of second guide formations 8D, 8E formed by opposite sides of a cut-out 8C in a middle part of the docking adapter 8. During lowering of the top Waste receivingtank section 4 onto the bottom Waste storage and discharge tank section 2 said guide pins19A, 19B cooperate with the associated pair of second guide formations 8D, 8E to lift thehook~shaped free outer ends of the locking arms 18A, 18B from the guide members 20A,20B. As was mentioned above the docking adapter 8 also has a pair of first guide formations8A, 8B in the shape of grooves 8A and 8B that extend at an angle from an open end at a topedge of the docking adapter 8 and to a closed end adjacent a respective side edge thereof. Saidfirst guide fonnations 8A, 8B serve to receive outer free ends of the associated guide member20A, 20B as the top waste receiving tank section 4 is lowered onto the bottom waste storageand discharge tank section 2. The angled configuration of the grooves of the first guideformations 8A, 8B and their cooperation with the associated guide member 20A, 20B will effectively maintain the bottom walls 11A, 1 lB in their open emptying position II.
    In use of the waste managing assembly 1 outer ends of the guide members 20A, 20B cooper-ate with the docking adapter 8 first guide formations 8A, 8B to control bottom wall operationbetween the blocking position I closing the waste communication between the lower part 10of the top waste receiving tank section 4 and the bottom waste storage and discharge tanksection 2 and the open emptying position II opening said waste communication. In said openemptying position II introduced waste is released to fall from the top waste receiving tanksection 4 into the bottom waste storage and discharge tank section 2, through its open upperpart 9. In the basic embodiment the bottom walls 11A, 1lB are automatically moved bygravity from their open emptying position II to their closed and looked position I. This isinitiated as soon as the top waste receiving tank section 4 is lifted up from the bottom wastestorage and discharge tank section 2 to disengage the bottom wall 11A, 1lB supportassemblies 18 from the interface 7 adapter 8. Only one end of the waste managing assembly 1is shown in the drawings but it should be understood that in a preferred embodiment theopposite ends of the waste managing assembly 1, including the top waste receiving tanksection 4 with is bottom walls 11A, 1lB, the bottom waste storage and discharge tank section 2 and the interface 7, are identical but mirror images of each other.
    In further development of the waste managing assembly 1 of this technology sensors (not shown) may be provided in association with the lower part 10 of the top waste receiving tank 9 section 4 and/or in association with the docking adapter 8 at the upper part 9 of the bottomwaste storage and discharge tank section 2. The sensors that are i.e. of the contact orproximity type serve to initiate, immediately or alternatively with a set delay, the applicationof air flow through the waste transport pipe 101 and to the bottom waste storage and discharge section 2 of the tank 2, 4 when the top waste receiving tank section 4 has been removed.
    The technology also involves a method of managing waste by means of a waste managing assembly 1 as described above. Sequential stepsneeëheé will be generally described with reference to the drawings. ln a first step the top wastereceiving tank section 4 of the composite waste material tank 2, 4 of the waste managingassembly 1 is positioned with the bottom walls 11A, 11B closed and looked at a wasteintroduction point 103. The waste introduction point 103 is normally separate from a wastedeposit and discharge point 102 where an associated bottom Waste storage and discharge tanksection 2 of the composite waste material tank 2, 4 is positioned and supported. Waste isintroduced through the at least one waste introduction opening 5 and is received and collectedin the top Waste receiving tank section 4. At an appropriate time, such as when the top wastereceiving tank section 4 is full or when construction work is finished at a site forming thewaste introduction point 103 the top waste receiving tank section 4 with introduced waste istransported to a designated Waste deposit and discharge point 102 of the pneumatic materialcollection and transport system 100. ln the next step the top waste receiving tank section 4 ispositioned above the associated bottom waste storage and discharge tank section 2 and islowered onto the interface 7 to dock the lower part 10 of the top waste receiving tank section4 on the open upper part 9 of the bottom waste storage and discharge tank section 2. Thisdocking action causes Swinging and sliding of the bottom walls 11A, l1B of the top wastereceiving tank section 4 from the closed blocking position I to the open emptying position II,releasing communication between the lower part 10 of the top Waste receiving tank section 4 and the open upper part 9 of the bottom waste storage and discharge tank section 2.
    When appropriately emptied, prior to or subsequent to pneumatic discharge of waste materialfrom the bottom Waste storage and discharge tank section 2, the top waste receiving tanksection 4 may be lifted off from the bottom waste storage and discharge tank section 2 and itsinterface 7. By such action, the guide pins 19A, l9B of the looking arms 18A, 18B of the support assembly 18 cooperate with the associated pair of second guide formations 8D, 8E of the docking adapter 8 to maintain the hook-shaped free outer ends of the looking arms 18A,l8B in their position. Simultaneously the outer ends of the guide members 20A, 20B co-operate with the first guide formations 8A, 8B to cause the bottom walls 11A, 11B to swingand slide back to their closed position 1. This occurs prior to the release of the looking arms18A, 18B of the support assembly 18 as soon as the guide pins 19A, 19B leave the secondguide formations 8D, 8E. This allows the looking arms 18A, l8B to swing down into lookingengagement of their free outer ends with the outer ends of the bottom wall 11A, 11B guidemembers 20A, 20B. The bottom walls 11A, 11B are thus closed and looked and the top waste receiving tank section 4 may be returned to its designated waste introduction point 103. ln a further step air flow may be manually or automatically initiated through a waste transportpipe 101 of the pneumatio material collection and transport system 100 and to the bottomwaste storage and discharge section 2 of the tank 2, 4. This air flow serves to transportcollected material from the waste tank 2, 4, when the lower part 10 of the top waste receivingtank section 4 has docked on the open upper part 9 of the bottom waste storage and dischargetank section 2. ln further development flyg application of waste transport airflow to the bottom waste storage and discharge section 2 of the tank 2, 4 may be initiated byopening a discharge valve DV, provided downstream of the tank 2, 4, in response to signalsgenerated by sensors, such as contact or proximity sensors, provided in association with thelower part 10 of the top waste receiving tank section 4 and/or in association with the docking adapter 8 fixed to the open upper part 9 of the bottom waste storage and discharge tank section 2.
    Thus, the technology includes the bottom tank section 2 resembling the screw part of a screwtank type and being connected to a pneumatic material collection and transport system 100. ltincludes the at least one top tank section 4 that is “portable” and may be placed at optionalwaste introduction points 103 without being connected to any pneumatic waste materialcollection and transport system 100. Users introduce waste into said top tank section 4 andwhen it is full it is transported to the bottom tank section 2 and is automatically emptied intothe pneurnatic waste material collection and transport system 100. The interface 7 and itsdocking adapter 8 serve to control the bottom walls 11A, 11B of the top tank section 4 and also to secure said bottom walls in a looked state during transport of the top tank section 4. 11 ln alternative, but not specifically illustrated embodiments of the technology Variations of thedifferent illustrated parts of the suggested units may be employed without departing from thescope of the technology. It shall be emphasized that although the technology has beendescribed and illustrated with specific reference to an application in a vacuum operated Wastecollection and transport system, the technology is in no Way restricted to such applications.
    The basic principles of the technology may be applied to other pneumatic transport fields.
    The technology has been described in connection With what is presently considered the mostpractical and preferred embodiments but it is to be understood that it is not limited to thedisclosed ernbodiments. The technology is therefore intended to cover various modifications and equivalent arrangernents included within the spirit and scope of the appended claims.
