BACKGROUND
Typically, packing a substance, especially a hazardous substance having micron sized nano particles, in a container is a cumbersome task due to high standards of safety and precision required while handling such substances. Also, probability of spillage and risk of inhalation of such substances is higher when compared to other substances such as cosmetic powders, edible powders, etc. Lack of precision while packing such substances may result in a compromised safety and an increased wastage, thereby increasing costs associated therewith. Lack of precision in terms of compactness when experienced while packing test samples (e.g., magnetic materials tested for magnetic hysteresis) results in a compromised quality of test results. Lack of precision while packing such substances in containers having low resistance to breakage and fracture may result in additional costs.
Conventional packing apparatuses (e.g., apparatuses used in food and beverage, pharmaceutical or chemical industry setups) often are equipped with complex mechanisms and occupy large spaces. Such packing apparatuses are typically configured for mass packing and therefore fail to cater to customized applications where the substances and/or the containers for which the packing apparatuses are configured may vary frequently.

DETAILED DESCRIPTION
FIG. 1A illustrates an isometric view of one embodiment of a packing apparatus 100. The packing apparatus 100 is used for packing a substance in a container 109. The substance includes, for example, a solid substance such as powders, a liquid substance such as chemicals, or a gaseous substance being filled under pressure, etc. The substance is, for example, a nano powder such as chromium dioxide. The container 109 is, for example, a quartz tube. In an embodiment, the container 109 is a vial, a capsule, a bottle, or another container. The packing apparatus 100 includes a filling unit 101 including a moveable filling member 102 moveable from at least a first filling position to a second filling position. As used herein, “first filling position” refers to a position in which the moveable filling member 102 is in a retracted state. Also, as used herein, “second filling position” refers to a position, as illustrated in FIG. 1A, in which the moveable filling member 102 is in an extended state. The moveable filling member 102 is longitudinally moveable along YY axis. In an embodiment, the moveable filling member 102 is rotatably moveable about ZZ axis. In this embodiment, the moveable filling member 102 may be a non-extendable moveable filling member. In this embodiment, the first filling position of the moveable filling member 102 is a position aligned with XX axis, and the second filling position is a position aligned with the YY axis. A mechanical drive (e.g., a pneumatic drive) enables movement of the moveable filling member 102 from the first filling position to the second filling position and from the second filling position to the first filling position. The filling unit 101 is configured to facilitate filling of the substance in the container 109.
The packing apparatus 100 further includes a compacting unit 103 including a moveable compacting member 103A moveable from at least a first compacting position to a second compacting position. As used herein, “first compacting position” refers to a position, as illustrated in FIG. 1A, in which the moveable compacting member 103A is in a retracted state. Also, as used herein, “second compacting position” refers to a position in which the moveable compacting member 103A is in an extended state. A mechanical drive (e.g., a linear servo drive) enables movement of the moveable compacting member 103A from the first compacting position to the second compacting position and from the second compacting position to the first compacting position. The compacting unit 103 is configured to compactly pack the filled substance in the container 109. The moveable compacting member 103A moves from the first compacting position, which is a home position of the moveable compacting member 103A, to the second compacting position with a preconfigured compaction force. The preconfigured compaction force is a function of one or more properties of the container 109. The properties include, for example, hoop stresses of the container from which a capacity of the container 109 to sustain maximum load (e.g., weight of the substance) without breakage may be derived. For example, when the container 109 is a quartz tube having an inner diameter di of 8 millimeter (mm), an outer diameter do of 10 mm, and a length of the quartz tube L of 50 mm, then based on the hoop stresses (e.g., breaking stresses of the container 109) and based on iterative experimentation, a limiting force is calculated as 12.5 Newton (N). Thus, the moveable compacting member 103A is moved with the preconfigured compaction force of less than 12.5 N to avoid breakage of the container 109 (e.g., the quartz tube) for packing the filled substance with maximal compactness. The filling of the substance is performed in multiple steps followed by packing of the filled substance. The packing of the filled substance is performed at least thrice after each substance fill. The packing apparatus 100 thus packs the substance in the container 109 by employing a displacement force feedback mechanism based on the preconfigured compaction force of the moveable compacting member 103A.
As illustrated in FIG. 1A, the moveable compacting member 103A is in a first compacting position (e.g., a retracted state), and the moveable filling member 102 is in a second filling position (e.g., in an extended state). At least one of the first compacting position and the second compacting position of the moveable compacting member 103A is in relation with at least one of the first filling position and the second filling position of the moveable filling member 102. For example, when the moveable filling member 102 is in the first filling position (e.g., a retracted state), the moveable compacting member 103A is in the second compacting position (e.g., an extended state), and when the moveable filling member 102 is in the second filling position (e.g., an extended state), the moveable compacting member 103A is in the first compacting position (e.g., a retracted state). In an embodiment, the moveable filling member 102 and the moveable compacting member 103A are in the first filling position and the first compacting position, respectively (e.g., both are in a retracted state, at a given time instant).
For purposes of illustration, the detailed description refers to a first filling position and a second filling position of the moveable filling member 102 and a first compacting position and a second compacting position of the moveable compacting member 103A. However, the scope of the method and packing apparatus 100 disclosed herein is not limited to the above positions but may be extended to include more than two positions for the moveable filling member 102 and the moveable compacting member 103A, respectively, and an unlimited number of combinations of each of these positions for synchronization of movement of the moveable filling member 102 with the moveable compacting member 103A, as disclosed in the detailed description of FIG. 1E.
The filling unit 101 further includes a transferring assembly 104 rigidly connected to the moveable filling member 102. The transferring assembly 104 includes a transferring member 104A positioned concentric to the moveable compacting member 103A in one of the first filling position and the second filling position of the moveable filling member 102. As illustrated in FIG. 1A, the transferring member 104A is concentric to the moveable compacting member 103A when the moveable filling member 102 is in the second filling position (e.g., in an extended state). The transferring member 104A is, for example, a funnel shaped member used to receive and transfer a substance into the container 109. The transferring member 104A is rigidly connected to the moveable filling member 102 via a connection member 104B of the transferring assembly 104. In an embodiment, the transferring assembly 104 further includes a transfer enhancer (e.g., a transfer enhancing device such as a vibratory media configured to enable transfer of sticky substances to the container 109). The packing apparatus 100 further includes a base assembly 105 configured to receive the container 109 and securely position the container 109 concentric to the moveable compacting member 103A of the compacting unit 103. The packing apparatus 100 further includes a collector assembly 106 for collecting spilled substance being filled via the transferring member 104A of the filling unit 101 into the container 109.
The packing apparatus 100 further includes a storage unit 107 positioned proximal to the base assembly 105. The storage unit 107 stores the substance to be packed into the container 109. The substance may be transferred from the storage unit 107 to the transferring member 104A, for being filled into the container 109, using a substance carrier 108. The substance carrier 108 is, for example, a ladle, a spatula, a spoon, etc. To preclude spillage of the substance after collecting the substance in the substance carrier 108, the substance in the substance carrier 108 may be leveled against a leveler 107A of the storage unit 107. The leveler 107A provides that an equal quantity of substance is transferred from the storage unit 107 to the container 109 in every fill.
FIG. 1B illustrates an elevation view of the packing apparatus 100 including the filling unit 101 including the moveable filling member 102 and the transferring assembly 104. The compacting unit 103 includes the moveable compacting member 103A and the base assembly 105. In an embodiment, the moveable filling member 102 includes two or more parallel shafts 102A and 102B moveable from the first filling position to the second filling position, as disclosed in the detailed description of FIG. 1A. FIG. 1C illustrates an enlarged view of a portion of the packing apparatus 100 marked “A” in FIG. 1B, showing an axis CC of alignment of the moveable compacting member 103A, the transferring member 104A of the transferring assembly 104, and the base assembly 105 of the packing apparatus 100. In this alignment, the moveable filling member 102, to which the transferring member 104A is attached via the connection member 104B of the transferring assembly 104, is in the second filling position. The base assembly 105 includes an annular member 111 and a tubular member 110. The container 109 is securely positioned inside the tubular member 110 aligned with the axis CC and concentric to the transferring member 104A and the moveable compacting member 103A. The collector assembly 106 is positioned on the base assembly 105 such that the collector assembly 106 is concentric to the transferring member 104A and the moveable compacting member 103A along the axis CC.
FIG. 1D illustrates an isometric view of the packing apparatus 100 showing the moveable filling member 102 in a first filling position and the moveable compacting member 103A in a second compacting position. When the moveable filling member 102 is in the first filling position (e.g., in a retracted state), the moveable compacting member 103A is in the second compacting position (e.g., in an extended state). This synchronization between the moveable filling member 102 and the moveable compacting member 103A provides safety of operation while packing a substance in the container 109. To achieve this synchronization, two proximity sensors (not shown) may be fitted on the moveable filling member 102. The two proximity sensors detect a position of the moveable compacting member 103A and communicate the detected position to a control unit (not shown) that controls movement of the moveable filling member 102 based on the detected position of the moveable compacting member 103A. In an embodiment, the moveable filling member 102 remains in the second filling position (e.g., an extended state), and the moveable compacting member 103A moves from the first compacting position to the second compacting position through the transferring member 104A of the transferring assembly 104 connected to the moveable filling member 102, along the axis CC, as illustrated in FIG. 1C. In this embodiment, a cross sectional size of the transferring member 104A is configured such that the moveable compacting member 103A may move through the transferring member 104A to the second compacting position. FIG. 1E illustrates an embodiment of the packing apparatus 100 illustrated in FIGS. 1A, 1B, and 1D, showing multiple positions of the moveable compacting member 103A. In this embodiment, the moveable compacting member 103A moves from the first compacting position, which is a home position P1 to an intermediate position P2, and from the intermediate position P2 to the second compacting position, which is an end position P3, along the axis CC. The intermediate position P2 is a transitional position at which the moveable compacting member 103A is proximal to the container 109 (e.g., about to enter the container 109) for compactly packing the filled substance in the container 109. In this embodiment, the moveable compacting member 103A moves from position P1 to P2 at a speed higher than that from position P2 to P3. This transition of speed at which the moveable compacting member 103A moves from position P2 to P3 (e.g., after entering the container 109) is determined based on the preconfigured compaction force in order to preclude breakage of the container 109.
FIG. 2 illustrates an enlarged view of the moveable compacting member 103A of the packing apparatus 100 illustrated in FIGS. 1A, 1B, and 1D. A cross sectional size of the moveable compacting member 103A is in relation with a cross sectional size of the container 109 illustrated in FIGS. 1A and 1C. The moveable compacting member 103A may be of a circular cross section, a spherical cross section, a triangular cross section, etc. such that the moveable compacting member 103A packs the filled substance into the container 109 with maximal compactness. A lower end 103B of the moveable compacting member 103A is tapered for enabling packing of the substance in the container 109 with minimum spillage of the substance and minimal airlock between the moveable compacting member 103A and the container 109. In order to reduce the spillage during the packing, the lower end 103B is back tapered at an angle α of 5°. This back taper precludes vacuum creation in the container 109 when the moveable compacting member 103A has packed the filled substance and is moving back from the second compacting position to the first compacting position of the moveable compacting member 103A. In an embodiment, the moveable compacting member 103A is replaceable and may be replaced after packing the substance in a predefined number of containers 109.
FIG. 3 exemplarily illustrates an enlarged isometric view of a collector assembly 106 of the packing apparatus 100 exemplarily illustrated in FIGS. 1A, 1B, and 1D. The collector assembly 106 collects spilled substance. The collector assembly 106 includes a first collector tray 106A removably connected to a second collector tray 106B. This split type configuration of the collector assembly 106 enables ease of cleaning of the collector assembly 106. The first collector tray 106A and the second collector tray 106B, when connected, define a space 106C therewithin for receiving the tubular member 110 of the base assembly 105, exemplarily illustrated in FIG. 1C. The container 109 is positioned inside this tubular member 110. To provide minimum spillage of substance while the substance is being filled in the container 109 via the transferring member 104A of the transferring assembly 104 illustrated in FIGS. 1A-1D, the transferring member 104A and the container 109 are positioned with maximal proximity therebetween. However, if the substance spills while being filled into the container 109, this spilled substance is collected in the collector assembly 106. This spilled substance may later be transferred from the collector assembly 106 to the storage unit 107 illustrated in FIG. 1A.
FIGS. 4A-4B illustrate embodiments of the base assembly 105 of the packing apparatus 100 illustrated in FIGS. 1A, 1B, and 1D showing container securing device 112 and 114 (e.g., container securer). The base assembly 105 includes at least one container securing device 112 and 114 (e.g., container securer) including mechanical device 112 and electrical device 114 (e.g., mechanical and electrical elements). The container securing device 112 and 114 secures the container 109 inside the tubular member 110 to preclude suctioning of the container 109 during movement of the moveable compacting member 103A from the second compacting position to the first compacting position, illustrated in FIGS. 1A-1D. FIG. 4A illustrates the base assembly 105 including a mechanical container securing device 112. The mechanical container securing device 112 includes, for example, two or more ring members 112 positioned in parallel to one another in an inner void 110A defined within the tubular member 110 of the base assembly 105. The ring members 112 may be positioned in multiple configurations along the length L of the tubular member 110. For example, the ring members 112 may be positioned proximal to one another towards a bottom end 110B of the tubular member 110 or towards a top end 110C of the tubular member 110. Alternatively, one of the ring members 112 may be positioned proximal to the bottom end 110B, and other ring member 112 may be positioned proximal to the top end 110C of the tubular member 110. The tubular member 110 is configured to define the inner void 110A therewithin for receiving the container 109. Each of the ring members 112 may be configured of a material, for example, rubber, silicon, etc., that enables the container 109 to be securely positioned inside the tubular member 110 and also increases breaking stress capacity of the container 109. In an embodiment, a cushion 113 is placed at the bottom end 110B of the tubular member 110 to enable the container 109 to sustain load of the moveable compacting member 103A without breakage, by absorbing the impact of the moveable compacting member 103A. The cushion 113 may be configured of rubber, silicon, paper, foam, or any combinations thereof. FIG. 4B illustrates the base assembly 105 including an electrical container securing device 114. The electrical container securing device 114 includes, for example, a vacuum unit 114. The vacuum unit 114 creates a negative air pressure in the inner void 110A of the tubular member 110 to secure the container 109 in a position concentric to the moveable compacting member 103A. The container securing device 112 and 114 secures the container 109 such that the container 109 is maintained in an original position when the moveable compacting member 103A is moving back from the second compacting position to the first compacting position.
