Description

TECHNICAL FIELD

[0001] The present disclosure relates to a sealing apparatus used in conjunction with vacuum packaging machines for sealing items in plastic bags, and more particularly relates to the sealing apparatus that is compatible with several types of vacuum packaging machines used in several industrial, commercial, and domestic applications.BACKGROUND

[0002] A vacuum packaging machine is a device used to create a vacuum environment within a sealed chamber. This is achieved by removing air or other gases from the chamber, resulting in a near-zero pressure environment. Vacuum chamber machines are commonly used in various industries, including food packaging, medical device manufacturing, and laboratory research, for sealing and preserving products. A typical sealing process includes the following steps: (1) a product to be sealed is placed inside a heat-sealable pouch or bag, (2) the pouch or the bag containing the product is then placed inside a vacuum chamber and an open end of the pouch or the bag is located in between two jaws (one movable seal bar and another a counterpart), where one of the sealing bars has a heated wire assembled thereupon, (3) the vacuum chamber is sealed, creating an airtight environment, (4) a vacuum pump is activated, which removes air or other gases from the vacuum chamber, reducing the pressure inside, (5) as the vacuum is created, the pressure difference between the inside and outside of the pouch causes the pouch to collapse, at the same time, electric current is applied to the heating wire causing the heating wire to heat up and melt the plastic layers at the open end of the pouch and creating a hermetic seal.

[0003] The existing standard is that an operator has to set a time, for instance, between 1.5-3.0+ seconds, in steps of 1 / 10th of a second. The timer indirectly controls the temperature by way of the amount of electrical current supplied to the heating wire. This means the temperature setting is unknown and involves guesswork. However, the heating wire temperature is the most important of the three parameters (time, temperature, and pressure) and should be set to a specific temperature based on the chemical composition of the film that is being used as bag material. When the operator sets the time too long or too short, the seal will not be solid and break. In case of too much heat, which is a common issue, a protective non-stick Teflon tape on the seal wire would burn through and need to be replaced. Furthermore, the pressure between the two sealing bars is linked to the air pressure in the chamber. In the case of operating at a low vacuum level of less than 40% or 600 mBar, the pressure between the two sealing bars starts to become insufficient for a proper seal. In use with liquids, there is a risk of liquid entering a membrane component of the seal system and increased contamination of vacuum pump oil, which leads to malfunctioning of the vacuum packaging machine and hygiene problems.

[0004] Furthermore, the sealing bars are awkwardly mounted and require tools that are not commonly available in this kind of operation, which leads to a lack of cleaning by operators. In addition, any malfunction normally requires a costly on-site visit from a trained technician. Also, the non-modular assembly of the sealing bars leads to time-consuming steps of disassembly and reassembly. High maintenance and repair costs lead to decisions to omit repair and shorten the lifetime of the overall device. Furthermore, components of the sealing subsystem are non-standard and are not compatible with machines of different sizes or makes. Therefore, there is a need in the art for a modular sealing apparatus that overcomes at least some of the limitations and deficiencies presented in the aforementioned discussion.SUMMARY

[0005] Various embodiments of the present disclosure disclose a modular sealing apparatus.

[0006] In an embodiment, a modular sealing apparatus is disclosed. The modular sealing apparatus includes a cap module, an actuation box, an interface module, and a main controller.

The interface module is configured to detachably couple the actuation box to a lid member of a vacuum packaging machine. The interface module defines a modular utility interface configured to provide detachable routing of one or more utilities between the vacuum packaging machine and the actuation box. The main controller is communicably coupled to the actuation box, the interface module, and the cap module. The main controller is configured to transmit a control signal to the actuator. The control signal is configured to operate an actuation assembly of the actuator to generate a linear displacement of an actuation member associated with the actuator. The linear displacement moves the cap module towards a counterpart during a sealing operation.

[0007] In another embodiment, a modular sealing apparatus for a vacuum packaging machine is disclosed. The modular sealing apparatus includes a cap module, an actuation box, an interface module, and a main controller. The cap module includes a central portion on which a heating wire is located. The heating wire is configured to heat based on a receipt of an electrical power. The actuation box is detachably coupled to the cap module. The actuation box includes an actuator disposed in the actuation box. The actuation box and the cap module are mounted to a lid member of the vacuum packaging machine, and a counterpart of the vacuum packaging machine is mounted inside a cavity of a lower compartment of the vacuum packaging machine. The interface module is configured to detachably couple the actuation box to a lid member of the vacuum packaging machine. The interface module defines a modular utility interface configured to provide detachable routing of one or more utilities between the vacuum packaging machine and the actuation box. The main controller is communicably coupled to the actuation box, the interface module, and the cap module. The main controller is configured to transmit a control signal to the actuator.

[0008] In another embodiment, a method of operating a modular sealing apparatus in a vacuum packaging machine is disclosed. The method, performed by a main controller, includes operating an actuator disposed in an actuation box detachably coupled to a cap module. The method includes transmitting a control signal to the actuator to generate a linear displacement of the cap module toward a counterpart. Further, the method includes facilitating the supply of electrical power to a heating wire located on a central portion of the cap module to perform a sealing operation. The method further includes operating an auxiliary controller to regulate one or more parameters of the vacuum packaging machine for performing the sealing operation.

[0009] In various embodiments, the modular sealing apparatus defines a self-contained sealing subsystem having a standardized mechanical interface and a standardized utility interface with the vacuum packaging machine. The standardized interfaces enable sealing-related components to be removed, replaced, serviced, or interchanged as a unit without requiring modification of machine-side structures, utility routing, or chamber geometry of the vacuum packaging machine. The modular architecture supports multiple actuation technologies and mounting orientations and enables sealing performance, accessibility, hygiene, and serviceability to be achieved independently of a mechanism by which sealing force is generated within the vacuum packaging machine.BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present disclosure relates to a modular sealing apparatus for a vacuum packaging machine. The vacuum packaging machine includes a cap module and an actuation box. The cap module includes a central portion on which a heating wire is located; the heating wire is heated based on electrical power inputs. The actuation box is detachably coupled to the cap module. The actuation box includes an actuator disposed in the actuation box, and the actuation box and the cap module are mounted to a lid member of the vacuum packaging machine. The actuator may be selected from a group consisting of a pneumatic actuator, an electronic actuator, and an electromechanical actuator. The vacuum packaging machine includes an interface module. The interface module detachably couples the actuation box to an internal surface of the lid member of the vacuum packaging machine. The lid member is configured with one or more cavities for receiving the actuation box. The modular sealing apparatus further includes a set of coupling members that is disposed on at least the actuation box and the interface module. The set of coupling members enables detachable pneumatic coupling of the actuation box and the interface module. Further, the electrical power to the heating wire is routed through a conduit extending through a hinge of the lid member.

[0023] In an embodiment, the actuation box and the cap module are mounted to the lid member of the vacuum packaging machine, and a counterpart is mounted inside the cavity of a lower compartment of the vacuum packaging machine. This mounting configuration of the vacuum packaging machine conforms to an inverted mounting configuration. Further, the actuator, such as a pneumaticactuator, is disposed within the actuation box. The actuation assembly of the pneumatic actuator includes a piston and cylinder assembly configured to provide the linear displacement of the actuation member to operate the cap module towards the counterpart during the sealing operation. The pneumatic actuator is configured to generate the linear displacement to operate the cap module downward toward the counterpart during the sealing operation.

[0024] Further, the vacuum packaging machine includes a main controller. The main controller is communicably coupled to the actuation box, the interface module, and the cap module. The main controller is configured to transmit a control signal to the actuator. The control signal is configured to operate an actuation assembly of the actuator to generate the linear displacement of an actuation member associated with the actuator that moves the cap module towards the counterpart during a sealing operation. Furthermore, the modular sealing apparatus further includes an auxiliary controller communicably coupled to the main controller. The main controller will operate the auxiliary to control one or more parameters of the interface module for operating the cap module towards the counterpart during the sealing operation. The one or more parameters for the modular sealing apparatus include a sealing force, sealing duration, displacement of the cap module, and temperature of a heating wire.

[0025] Various example embodiments of the present disclosure are described hereinafter with reference to FIG. 1 to FIG. 5.

[0026] FIG. 1 illustrates a perspective view of a conventional vacuum packaging machine 100, in accordance with an embodiment of the present disclosure. The conventional vacuum packaging machine 100 (hereinafter also referred to as “vacuum packaging machine 100” or “machine 100”) includes a lower compartment 102 and a lid member 104. The lower compartment 102 defines a cavity 103 therein. When the lid member 104 is positioned over the lower compartment 102, the cavity 103 and the lid member 104 together define a vacuum chamber 106.

[0027] The machine 100 further includes a heating bar 110 disposed within the lower compartment 102. More specifically, the heating bar 110 is mounted on a floor (not shown in FIG. 1) of the vacuum chamber 106. The heating bar 110 is fixed in position and is neither modular nor interchangeable. In several embodiments, the heating bar 110 is configured to be displaced upward during a sealing operation by means of a vacuum-driven membrane or a cylinder actuator.

[0028] The machine 100 further includes a counterpart 108 mounted within the lid member 104. In particular, the counterpart 108 is mounted on a lower surface of the lid member 104 that faces the lower compartment 102. The counterpart 108 is fixedly mounted and is configured to engage the heating bar 110 when the lid member 104 is closed, such that the heating bar 110 and the counterpart 108 cooperate to seal packaging material positioned therebetween. However, the mounting arrangement of the heating bar 110 and the counterpart 108 of the machine 100 typically requires specialized tools for removal, cleaning, and maintenance, which are often unavailable to operators. During operation, the counterpart 108 remains stationary while the heating bar 110 is displaced upward by an actuator located within or beneath the vacuum chamber 106. This configuration hampers cleaning access and increases reliance on specialized service technicians.

[0029] The heating bar 110 includes a heating wire (not shown in FIG. 1) disposed thereon. In certain embodiments, the heating bar 110 further includes a cutting wire (not shown in FIG. 1) configured to sever excess packaging material following completion of the sealing operation. The heating wire and, where provided, the cutting wire may be covered with a protective non-stick film, such as a Poly-Tetra-Fluoroethylene (PTFE) film. It is to be that, in the machine 100, the electrical power and other utilities required for the operation of the heating wire are routed through fixed pathways within the lower compartment 102. Such utilities are not routed through a lid hinge (i.e., a hinge of the lid member 104). This embedded and fixed configuration limits modularity, prevents the use of interchangeable actuation technologies, restricts access for maintenance, and complicates cleaning of the vacuum chamber 106.

[0030] It is to be noted that the machine 100 lacks an internal vacuum-generating mechanism and is configured to rely on an external vacuum pump to evacuate the vacuum chamber 106. To this end, the machine 100 is provided with an exhaust port 105 through which a vacuum pump (not shown in FIG. 1) removes air from the vacuum chamber 106, thereby generating a vacuum pressure relative to atmospheric pressure. The vacuum pump is fluidically coupled to the vacuum chamber 106 via one or more valves in communication with the exhaust port 105. The machine 100 may further include a control panel 111 configured to allow the operator to set operating parameters, including but not limited to a target vacuum level, sealing or melding time, and heating duration. The machine 100 may additionally incorporate safety features such as emergency stop buttons, safety interlocks, and protective covers for the operator.

[0031] In operation, a packet 112, made from a plastic material, is placed on the heating bar 110 such that an open end of the packet 112 overlies the heating bar 110. The lid member 104 is then moved to a closed position, thereby sandwiching an open end of the packet 112 between the heating bar 110 and the counterpart 108. Upon closing the lid member 104 and actuating the vacuum system, air is evacuated from the vacuum chamber 106 through the exhaust port 105, causing the packet 112 to collapse around its contents. Once the vacuum chamber 106 reaches a predetermined vacuum level, a valve applies vacuum to a membrane or vacuum-driven cylinder positioned beneath the heating bar 110, while atmospheric pressure acts on an opposing side thereof. The resulting pressure differential displaces the heating bar 110 upward, pressing the packet 112 against the counterpart 108. Electrical power is then supplied to the heating wire for a predetermined duration, causing the heating wire to heat and fuse layers of the packet 112 to form a seal.

[0032] By way of example, the heating process may occur at a temperature range of approximately 100-130 degrees Celsius, for a duration of about 1.5-2.5 seconds, and at a pressure between the heating bar 110 and the counterpart 108 of approximately 0.1-2 N / mm2. Following sealing, the vacuum pump is isolated, and the valve is switched to a venting position, allowing air to re-enter the vacuum chamber 106 and the membrane or cylinder actuator. The heating bar 110 returns to its initial position, and the lid member 104 may be opened to retrieve the sealed packet. The sealing operation results in the fusion of the plastic material at the previously open end of the packet 112. The material of the packet 112 may include, without limitation, Polyethylene, High-Density Polyethylene (HDPE), Low-Density Polyethylene (LDPE), Linear Low-Density Polyethylene (LLDPE), Polypropylene (PP), Ethylene Vinyl Acetate (EVA), polymer blends, and biopolymers. Removal of air from the packet 112 inhibits microbial growth and oxidation, thereby extending the shelf life of the packaged contents. The machine 100 may be used to vacuum package a wide variety of items, including but not limited to meat, cheese, dairy products, frozen foods, fruits and vegetables, medical and pharmaceutical supplies, electronic components, automotive parts, clothing, bedding, scientific samples, chemicals, and instruments.

[0033] Primary operating parameters of the machine 100 include sealing temperature, sealing pressure, dwell time, and packet material. Conventional vacuum packaging machines, such as the machine 100, typically rely on operator-selected sealing times, commonly between 1.5 and 3.0 seconds in 0.1-second increments, to indirectly control heating wire temperature. This approach makes precise temperature control difficult and relies heavily on operator judgment. Improper time settings may result in insufficient heating, leading to weak or incomplete seals, or excessive heating, which can damage the PTFE protective film covering the heating wire, necessitating replacement. Additionally, the pressure between the heating bar 110 and the counterpart 108 is dependent on the vacuum level in the vacuum chamber 106 and may be insufficient at low vacuum levels, such as below approximately 40% vacuum or 600 mBar.

[0034] However, at reduced vacuum levels, particularly when packaging liquids, there is an increased risk of liquid ingress into the membrane or actuator components of the sealing system, resulting in malfunction and hygiene concerns. Furthermore, the non-modular architecture of the machine 100 increases maintenance costs, discourages timely repair, and may shorten the operational lifespan of the machine 100. For instance, because the heating bar 110 and the counterpart 108 are fixed, the machine 100 cannot internally generate sealing pressure independently of the chamber vacuum level. The fixed and embedded configuration of the heating bar 110 and the counterpart 108 further limits compatibility with the machine 100 of varying sizes or from different manufacturers, complicates maintenance and repair, and prevents the use of alternative actuation technologies or the routing of utilities through movable components, such as the lid hinge.

[0035] FIG. 2A illustrates a front view of a modular sealing apparatus 200 (hereinafter also referred to as “apparatus 200”), in accordance with an embodiment of the present disclosure. FIG. 2B illustrates an exploded view of the modular sealing apparatus 200 of FIG. 2A. The modular sealing apparatus 200 is configured to replace the heating bar 110 and its associated actuator from the machine 100.

[0036] The modular sealing apparatus 200 includes a cap module 202, an actuation box 204 (shown in FIG. 2B), and an interface module 206, each having a modular and detachable configuration. The actuation box 204 is detachably coupled to the cap module 202, the actuation box 204 being detachably coupled to the lid member 104 of the vacuum packaging machine 100 via the interface module 206. As shown in FIG. 2B, the interface module 206 is detachably coupled to the actuation box 204 at least on one lateral surface thereof and is further configured to detachably couple the actuation box 204 to an internal surface 206a of the lid member 104. In the representative embodiment, the interface module 206 is mounted on both a left lateral surface and a right lateral surface of the actuation box 204. Each interface module 206, on the left and right lateral surfaces of the actuation box 204, is configured to detachably connect the actuation box 204 to a corresponding left-side and right-side portion of the internal surface 206a of the lid member 104, respectively.

[0037] Further, the modular sealing apparatus 200 includes a set of coupling members (see, 228 of FIG. 2B). The set of coupling members 228 is disposed on at least the actuation box 204 and the interface module 206. In one example, the set of coupling members 228 may include quick-disconnect pneumatic couplings. Alternatively, the set of coupling members 228 may include push-fit couplings, barbed pneumatic couplings, threaded pneumatic couplings, swivel pneumatic couplings, and the like. The set of coupling members 228 is configured to enable detachable pneumatic coupling of the actuation box 204 and the interface module 206. More specifically, the set of coupling members 228 may include a male coupler (also referred to as a plug), operatively associated with the first component (such as the actuation box 204), and a female coupler (also referred to as a socket), operatively associated with the second component (such as the interface module 206). The plug includes a generally cylindrical body having a coupling profile, a locking groove formed circumferentially around the body, and a terminal sealing surface. The socket includes a housing defining an internal cavity, one or more locking members, such as balls or detents, disposed within the housing, a biasing spring, and one or more elastomeric sealing elements positioned to interface with the plug upon insertion. During coupling, the plug is axially aligned with the socket and advanced into the internal cavity of the socket. Further, an external sleeve of the socket is displaced against the biasing force of the spring, permitting the locking members to retract momentarily. As the plug reaches its fully inserted position, the locking members are biased into the locking groove of the plug, thereby securing the plug against unintended axial withdrawal. Simultaneously, the sealing elements of the socket circumferentially engage the plug, creating an airtight interface between the interface module 206 and the actuation box 204.

[0038] In several embodiments, the interface module 206 defines a modular utility interface that establishes a functional boundary between the the modular sealing apparatus 200 and the vacuum packaging machine 100. The interface module 206 is configured to provide detachable routing of one or more utilities, including pneumatic, vacuum, electrical, and data connections, between the vacuum packaging machine 100 and the actuation box 204, such that the actuation box 204 may be removed, replaced, or interchanged without modification of machine-side utility routing or dependence on a specific actuator type. The interface module 206 thereby enables the sealing apparatus 200 to support multiple actuation technologies, including pressure-differential-based actuation and electrical or electromechanical actuation, and alternative utility routing approaches without redesign of the modular sealing apparatus 200 or the vacuum packaging machine 100.

[0039] It is to be noted that the interface module 206 does not function as a mechanical mounting bracket for the actuation box 204. Instead, the interface module 206 and the actuation box 204 are each independently configured to detachably engage the internal surface 206a of the lid member 104 using respective molded retention and alignment features. After installation, the interface module 206 and the actuation box 204 mate with one another to establish utility routing, while the interface module 206 does not structurally support, suspend, or carry the load of the actuation box 204 relative to the lid member 104.

[0040] Additionally, the interface module 206 provides operating connections for the actuation system and, in certain embodiments, for one or more sensing systems. Such operating connections include pneumatic routing configured to selectively deliver negative pressure or atmospheric air to an actuator 208 disposed within the actuation box 204, depending on a stage of a sealing cycle. The operating connections further include electrical power delivery to a heating wire 220 disposed in the cap module 202 and, in embodiments in which the actuator 208 is an electric or electrochemical actuator, electrical power delivery to the actuator 208.

[0041] The interface module 206 further provides data communication pathways configured to transmit control signals or status information between an auxiliary controller disposed within the modular sealing apparatus 200 and a main controller of the vacuum packaging machine 100. In some embodiments, the interface module 206 permits direct routing of data from one or more sensors, including position sensors, temperature sensors, strain sensors, or other embedded sensors, to the main controller. In embodiments in which the modular sealing apparatus 200 is integrated into an inverted-lid configuration, the interface module 206 further routes data from an optional sensor module, including infrared sensors and / or a camera, through a physical data line to the main controller. The main controller is communicably coupled to the actuation box 204, the interface module 206, and the cap module 202.

[0042] The interface module 206 further provides a power supply connection to the auxiliary controller disposed within the modular sealing apparatus 200 through a pin-style electrical connector integrated into the interface module 206. All pneumatic, electrical, and data connections provided by the interface module 206 are configured to be detachable, thereby permitting rapid removal, replacement, cleaning, servicing, or upgrading of the actuation box 204. In some embodiments, one or more interface modules 206 are positioned on opposing sides of the lid member 104 to simplify routing and maintain symmetry, without the interface modules 206 serving as structural supports. The system boundary is such that the machine-side utility routing remains fixed within the lid member 104, while the sealing-system components, including the cap module 202 and the actuation box 204, can be removed or replaced as a single modular unit without disassembling the vacuum chamber 106 or interfering with the fixed machine-side utilities. This ensures that routine maintenance, cleaning, or replacement of the modular sealing system can be performed independently of the machine-side infrastructure.

[0043] As shown in FIG. 2A, the actuation box 204 and the cap module 202 are mounted to the lid member 104 of the vacuum packaging machine 100. The actuation box 204 includes the actuator 208 and an actuation member 210. The actuator 208 is disposed in the actuation box 204. The actuation box 204 of the representative example is configured with two actuators (herein collectively referred to as the actuator 208) disposed on each of a left side and a right side of the actuation box 204. The actuation member 210 may be coupled to the actuator 208, disposed in the actuation box 204, using conventional coupling means, such as a snap-fit arrangement or a friction-based fastening, for convenient removal and reassembly of the actuator 208. Furthermore, the actuation member 210 may be coupled to the cap module 202 using a snap-fit arrangement or a friction-based fastening for convenient removal and reassembly of the cap module 202 from above the actuation box 204. Furthermore, a portion of the actuation member 210 protruding outside the actuation box 204 is protected from environmental elements by encapsulation using an actuation member sleeve 205 and an actuation member sealing ring 212. The actuation member sleeve 205 and the actuation member sealing ring 212 prevent environmental elements, like dust, moisture, etc., from entering the actuation box 204 and the actuator 208, ensuring their durability and longevity.

[0044] Further, the counterpart 108 is mounted inside the cavity 103 of the lower compartment 102 of the vacuum packaging machine 100. The actuation box 204 and the cap module 202 are mounted to the lid member 104, and the counterpart 108, being mounted inside the cavity 103 of the lower compartment 102 of the machine 100, conforms to an inverted mounting configuration of the modular sealing apparatus 200. The counterpart 108 is detachably mounted within the cavity 103, allowing removal for cleaning, servicing, or replacement without permanently altering or penetrating the structure of the vacuum chamber 106. When installed, the counterpart 108 maintains a smooth, uninterrupted, and hygienically cleanable interior surface of the vacuum chamber 106, preserving a seamless chamber interior and minimizing crevices or exposed components.

[0045] Hence, to accommodate the installation of the actuation box 204 on the lid member 104, the lid member 104 may be formed with one or more cavities 214 configured to receive the actuation box 204 and provide structural support during sealing operations. Furthermore, electrical, pneumatic, vacuum, and data channels may be routed through a conduit extending through a hinge 209 (shown in FIG. 2D) of the lid member 104. This hinge-routing option avoids penetration into the tub wall, preserves a fully seamless chamber interior, simplifies hygienic design, and provides manufacturing advantages for certain OEMs. Such an arrangement is enabled by the modular architecture of the modular sealing apparatus 200. Depending on machine design constraints, routing through the hinge 209 or through the tub wall may be selected, and both configurations are supported by the modular sealing apparatus 200.

[0046] Further, without limitation, electrical, pneumatic, vacuum, and data channels may be routed through a conduit extending through the hinge 209 of the lid member 104. This hinge-routing option avoids penetration into the tub wall, preserves a fully seamless chamber interior, simplifies hygienic design, and provides manufacturing advantages for certain OEMs. Such an arrangement is enabled by the modular architecture of the modular sealing apparatus 200. Depending on machine design constraints, routing through the hinge 209 or through the tub wall may be selected, and both configurations are supported by the modular sealing apparatus 200. Furthermore, the electrical power routed to the heating wire 220 of the cap module 202 may be conducted through a conduit extending through the hinge 209 of the lid member 104. This ensures the removable and pivoting nature of the lid member 104 does not interfere with the power supply or control-signal routing. The modular design enables the inverted mounting configuration to be employed selectively based on vacuum-machine form factor, chamber depth, the lid member construction, ergonomic considerations, or sealing-performance requirements. It will be understood that such routing arrangements are optional integration choices and are not defining features of the inverted mounting configuration.

[0047] FIGS. 2C and 2D show schematic representations of the modular sealing apparatus 200 in an inverted mounting configuration, in accordance with an embodiment of the present disclosure. As shown in FIGS. 2C and 2D, the modular sealing apparatus 200 is expressly configurable in the inverted mounting configuration, in which the cap module 202 and associated sealing elements are integrated into the lid member 104 of the vacuum packaging machine 100, while the counterpart 108 is positioned within the cavity 103 of the lower compartment 102. This inverted mounting configuration is a deliberate and selectable arrangement enabled by the modular architecture of the sealing apparatus 200 and is not intrinsic to modularity itself. In such embodiments, the lid member 104 may include one or more lid cavities configured to receive the actuation box 204 and associated components while maintaining structural integrity during sealing operations. Utility routing for the inverted mounting configuration may be achieved through multiple approaches, including routing through the hinge 209 (shown in FIG. 2D) of the lid member 104 or through alternative machine-side pathways, without limitation. Further, the inverted mounting configuration is compatible with multiple actuation technologies, including vacuum-derived pressure differential actuation and electrical or electromechanical actuation, such that no single actuator type or routing approach is required. This flexibility allows the inverted mounting configuration to be intentionally selected based on machine architecture, hygiene requirements, ergonomic considerations, or sealing-performance objectives.

[0048] The cap module 202 includes a central portion 216. The cap module 202 further includes at least one end connection portion 218 provided on at least one respective end of the central portion 216. As depicted in FIGS. 2A and 2B, there have been provided two end connection portions 218, one end connection portion 218 provided on each of a left side end and a right-side end of the central portion 216. Further, the heating wire 220 is disposed upon the central portion 216. In several embodiments, the heating wire 220 is fastened to the central portion 216 through one or both of the two end connection portions 218. In several embodiments, where the cap module 202 may include materials capable of conducting electricity or materials capable of being affected by heat or otherwise for general safety purposes, an insulation layer of an insulating material may be provided between at least the central portion 216 and the heating wire 220. The insulation layer may provide at least one of thermal insulation and electrical insulation from the heating wire 220.

[0049] Furthermore, in several embodiments, the heating wire 220 may be provided with a protective film 222 located upon the heating wire 220. The protective film 222 is configured to protect the heating wire 220 from environmental elements, such as oxygen, dust, moisture, etc., and from wear and tear during the usage of the modular sealing apparatus 200 in conjunction with the machine 100. In several embodiments, the protective film 222 may be made up of PTFE.

[0050] The heating wire 220 is configured to generate heat when supplied with electrical power. In the disclosed embodiments, electrical power for the heating wire 220 is sourced from the vacuum packaging machine 100. The electrical power is routed from the machine 100 through a hinge conduit into the lid member 104 and subsequently into the interface module 206. The interface module 206 is configured to provide detachable electrical connections, enabling routing of electrical power from the lid member 104 to the actuation box 204.

[0051] Within the actuation box 204, the electrical power is received and may pass through one or more control or switching elements configured to regulate the application of power to the heating wire 220. Such control elements may include, without limitation, relays, solid-state switches, or miniature controllers integrated into the actuation box 204. These control elements operate to selectively energize or de-energize the heating wire 220 during the sealing or melding process. It will be understood that no standalone electrical power supply unit is disposed within the cap module 202; the actuation box 204 functions as the primary electrical interface for supplying and controlling power to the heating wire 220.

[0052] From the actuation box 204, electrical power is routed into the cap module 202 via one or more electrical conductors or connectors. In some embodiments, the conductors may include quick-connect or snap-fit connectors to facilitate rapid assembly or disassembly of the cap module 202. The electrical power delivered to the heating wire 220 is sufficient to heat the wire to a predetermined temperature required for fusing the bag material during the sealing operation.

[0053] In certain embodiments, the modular sealing apparatus 200 may include sensing elements, such as temperature sensors, positioned in proximity to the heating wire 220. Electrical signals from such sensors may be transmitted through the same electrical path, via the cap module 202, the actuation box 204, and the interface module 206, back to the main controller of the machine 100 for monitoring and regulation of the heating process. The described architecture permits modular replacement of the cap module 202 and actuation box 204 without altering the primary electrical power path, while maintaining precise control over the heating wire 220.

[0054] The actuation box 204 is configured to operate the actuator 208 to provide a linear displacement required to move the cap module 202 downward toward the counterpart 108 during the sealing operation. The actuator 208 is disposed within the actuation box 204 and may be implemented using one or more actuation technologies, including, without limitation, a pneumatic actuator, a vacuum-driven actuator, an electronic actuator, an electromechanical actuator, or another linear actuation device. In vacuum-driven implementations, the actuator 208 is operated using a pressure differential generated by negative pressure supplied through a dedicated vacuum line and associated valve coupled to a vacuum pump or vacuum manifold. An opposing side of the actuator 208 may be vented to atmospheric pressure external to the vacuum chamber 106 or, in certain embodiments, selectively vented to pressure originating from within the vacuum chamber 106. Unlike conventional machines, such as the machine 100, which do not source vacuum or atmospheric pressure from within the vacuum chamber 106 for actuation, the actuator 208 disclosed herein is optionally configured to source negative pressure and / or return pressure from within the vacuum chamber 106 through controlled valve paths or venting arrangements enabled by the modular system architecture.

[0055] In embodiments employing the actuator 208 as a vacuum-driven pneumatic actuator, it operates based on a pressure differential between a first chamber and a second chamber. The negative pressure may be selectively supplied via a dedicated vacuum line connected to the vacuum pump or vacuum manifold, while the return pressure may be selectively supplied from ambient atmospheric air external to the vacuum chamber 106 or, in certain implementations, from within the vacuum chamber 106 through controlled venting pathways. In several embodiments, the actuator 208 may include an actuation assembly configured to convert a pressure differential or electrical input into linear mechanical motion for displacing the cap module 202. In pneumatic or vacuum-driven embodiments, the actuation assembly may include a piston and cylinder arrangement, wherein the piston is movably disposed within a cylinder and divides the cylinder into the first chamber and the second chamber. One or more piston seals may be provided to maintain a substantially airtight separation between the chambers. In some embodiments, the actuator 208 is configured as a single-acting device, wherein a biasing member, such as a spring, urges the piston toward an initial position in the absence of an applied pressure differential. In other embodiments, the actuator 208 is configured as a double-acting device, wherein the first and second chambers are selectively subjected to differing pressure conditions to achieve bidirectional displacement.

[0056] A valve 224 is fluidically coupled to one or more fluid channels 226 associated with the actuator 208. The valve 224 is configured to selectively control communication between the actuator chambers and one or more pressure sources, including a vacuum source, atmospheric vent, or chamber-derived pressure source. In operation, selective application of negative pressure or venting to atmospheric or chamber pressure generates a force acting on the piston, thereby translating the piston along a longitudinal axis of the cylinder. As the piston is displaced, the actuation member 210 coupled thereto correspondingly displaces, thereby moving the cap module 202 toward or away from the counterpart 108.

[0057] During operation, the actuator 208 is controlled by the main controller (not shown in FIGS. 2A and 2B) communicably coupled to the actuation box 204. The main controller transmits one or more control signals to regulate the operation of the actuator 208, including selective actuation, dwell time, and displacement magnitude. The control signals cause the actuation assembly to generate the linear displacement of the actuation member 210, thereby operating the cap module 202 toward the counterpart 108 during the sealing operation. The direction of displacement of the cap module 202 toward the counterpart 108 is indicated by directional arrow R1, as shown in FIGS. 3A and 3B. In some embodiments, the modular sealing apparatus 200 further includes an auxiliary controller communicably coupled to the main controller. The auxiliary controller may be configured to control one or more sealing parameters, including sealing force, sealing duration, displacement of the cap module 202, and temperature of the heating wire 220, for operating the cap module 202 towards the counterpart 108 during the sealing operation.

[0058] In at least some embodiments, the actuator 208, such as the electronic actuator, is arranged in an inverted mounting configuration, wherein the actuation box 204 is mounted to the lid member 104, and the counterpart 108 is disposed within the vacuum chamber 106. In such inverted configurations, the actuator 208 may be implemented using any suitable actuation technology, including pneumatic, vacuum-driven, electromechanical, or other linear actuation mechanisms. The disclosed system architecture, including the cap module 202, the actuation box 204, the interface module 206, the controller arrangement, and the inverted mounting configuration, is not limited to a particular actuation type and is configured to support multiple actuation technologies within the same modular framework.

[0059] Optionally, the modular sealing apparatus 200 may include a detachable sensor module, provided solely to collect monitoring data and not required for performing the sealing operation. The sensor module is a compact, detachable unit that can contain one or more sensing elements, including a miniature camera, infrared (IR) sensors, or a combination of both. The sensor module is positioned so that it has an unobstructed view of the sealing region and the goods being packaged. Its function is to capture visual and infrared data relating to the type and state of the items placed in the vacuum chamber 106, the condition of the packet 112 material, and any motion of the product during the sealing cycle. The sensor module interfaces with the actuation box 204 through a dedicated connector that provides power and a data link. Depending on the configuration, the collected data can be forwarded either through the actuation box 204 and the interface module 206 to the main controller, or directly to the main controller via a separate cable path. This optional module creates a defined hardware hook for future methods and software functions that rely on real-time sensing, analysis, and control enhancements without requiring changes to the design of the cap module 202 or the interface module 206.

[0060] The system-level modular architecture of the sealing apparatus 200 enables the sealing system to be fully detachable, serviceable, and replaceable without the need for tools, thereby facilitating rapid maintenance, cleaning, or replacement of individual modules, including the cap module 202, the actuation box 204, and the interface module 206. This architecture further allows the sealing system to be reconfigurable for multiple actuation variants, including pneumatic, vacuum-driven, electromechanical, or hybrid actuation mechanisms, without requiring structural modifications to the lid member 104 or the vacuum chamber 106. Moreover, the modular design permits integration into a flush, seamless, and cleanable interior of the vacuum chamber 106, minimizing crevices or exposed components and enhancing hygiene and maintenance. Such system-level modularity is not found in the conventional vacuum packaging machine 100. It underpins multiple novel advantages, including the ability to upgrade or customize the apparatus 200 for different operational requirements, packet sizes, or sealing protocols. Additionally, the modular arrangement enables the straightforward routing of utilities, including electrical power, vacuum, atmospheric air, and sensor data, through detachable interface connections, ensuring that modifications to one module do not impact the functionality of other modules.

[0061] FIG. 4 illustrates a detailed flow chart illustrating a method 400 of operation of the modular sealing apparatus 200, in accordance with an embodiment of the present disclosure. The method 400 depicted in the flowchart may be executed by, for example, the main controller or the auxiliary controller of the modular sealing apparatus 200. The method 400 starts at operation 402.

[0062] At operation 402, the method 400 includes operating, by the main controller, the actuator 208 disposed in the actuation box 204 detachably coupled to the cap module 202. In this operation, the main controller establishes communication with one or more control or switching elements disposed within the actuation box 204 and verifies operational readiness of the actuator 208. The operating step may include initializing the actuation box 204, confirming the availability of pneumatic, vacuum, or electrical utilities routed through the interface module 206, and enabling control logic associated with the actuation assembly. Due to the modular and detachable configuration of the actuation box 204, this operation may be performed without mechanical reconfiguration of the lid member 104 or the cap module 202.

[0063] At operation 404, the method 400 includes transmitting, by the main controller, the control signal to the actuator 208 to generate the linear displacement of the cap module 202 toward the counterpart 108. In response to the control signal, the actuator 208 operates the actuation assembly configured to convert a supplied pressure differential or electrical input into linear mechanical motion. In pneumatic or vacuum-driven embodiments, the control signal selectively actuates one or more valves to supply negative pressure, atmospheric air, or chamber-derived pressure to one or more chambers of the actuator 208, thereby displacing the actuation member 210. The linear displacement produced by the actuation member 210 moves the cap module 202 along the longitudinal axis toward the counterpart 108 to apply the sealing force during a sealing cycle.

[0064] At operation 406, the method 400 includes facilitating, by the main controller, the supply of electrical power to the heating wire 220 located on the central portion 216 of the cap module 202 to perform the sealing operation. Electrical power is routed from the vacuum packaging machine 100 through the lid member 104 and the interface module 206 to the actuation box 204, and from the actuation box 204 to the cap module 202 via one or more detachable electrical connectors. The main controller selectively energizes the heating wire 220 for the predetermined duration and at the predetermined power level sufficient to heat the heating wire 220 to a temperature required to fuse packaging material positioned between the cap module 202 and the counterpart 108. In certain embodiments, feedback from one or more temperature sensors positioned near the heating wire 220 is used by the main controller to regulate the supplied electrical power.

[0065] At operation 408, the method 400 includes operating, by the main controller, the auxiliary controller to regulate one or more parameters of the vacuum packaging machine 100 for performing the sealing operation. The auxiliary controller may be configured to control and monitor sealing-related parameters, including, without limitation, the sealing force applied by the cap module 202, the displacement distance and the dwell time of the actuator 208, the temperature of the heating wire 220, the vacuum level within the vacuum chamber 106, and the timing coordination between actuation and heating. The auxiliary controller communicates with the main controller through data pathways routed via the interface module 206, enabling coordinated control while preserving the modular and detachable nature of the sealing apparatus 200.

[0066] FIG. 5 is a simplified block diagram of a controller 500, in accordance with an embodiment of the present disclosure. The controller 500 is an example of the main controller or the auxiliary controller of the modular sealing apparatus 200. In an embodiment, the controller 500 may be a separate part and may be communicably coupled to the modular sealing apparatus 200.

[0067] The controller 500 includes at least one processor 505 for executing instructions. Instructions may be stored in, for example, but not limited to, a memory 510. The processor 505 may include one or more processing units (e.g., in a multi-core configuration). The processor 505 is operatively coupled to a communication interface 515, such that the controller 500 is capable of communicating with the components of the modular sealing apparatus 200, such as the actuation box 204, the cap module 202, the heating wire 220, the actuator 208, and the like.

[0068] The processor 505 is configured to transmit the control signal to the actuator 208 via the communication interface 515 to operate the actuation assembly of the actuator 208 to provide the linear displacement of the cap module 202 towards the counterpart 108 during the sealing operation. Further, the processor 505 may be configured to control the one or more parameters for operating the cap module 202 towards the counterpart 108 during the sealing operation. The one or more parameters may include the sealing force, the sealing duration, the displacement of the cap module 202, and the temperature of the heating wire 232. Further, one or more operations performed by the controller 500 are explained with reference to FIGS. 2A-2B to FIG. 4; therefore, they are not reiterated for the sake of brevity.

[0069] Embodiments of the modular sealing apparatus 200 as presented above offer several advantages. For instance, the modular sealing apparatus 200 has defined interfaces that allow the modular sealing apparatus 200 to fit with a wide range of existing vacuum packaging machine models from a variety of manufacturers. The modular design allows for easy, fast, no-tool removal and lower-cost replacements of components of the modular sealing apparatus 200. Furthermore, the modular sealing apparatus 200 as presented above can be used by anyone without requiring extensive training or soliciting the help of an operator specifically trained for operating vacuum packaging machines and related accessories. In addition, the use of sleeves and sealing elements, such as sealing rings prevent the ingress of foreign matter into the modular sealing apparatus 200. The core components can be standardized for the flexibility of interfacing with different chamber design variants. The modular sealing apparatus 200 enables a seamless or flush vacuum chamber surface enabling a hygienic design. The modular sealing apparatus 200 eliminates expensive maintenance issues by replacing membrane components and preventing leakage of liquid contents of packets or bags being sealed.

[0070] Furthermore, the temperature of the heating wire 220 and the melding time are controlled directly, independently, and within accepted tolerances. The operator does not have to worry about inconsistencies between various settings. In common cases of inconsistent electrical supply on the respective circuit, the modular sealing apparatus 200 also helps to eliminate those inconsistencies by directly controlling the temperature of the heating wire 220. In addition, the remaining critical parameter, i.e., the at least one of the contact force and the pressure between the cap module 202 and the counterpart 108, is also provided consistently. The sensor module, the pressure / force sensor feedback, and the independent control of actuators allow the decoupling of the contact force / pressure between the cap module 202 and the counterpart 108, from the vacuum in the vacuum chamber 106. Furthermore, the closed-loop control enabled by the sensor module enables predictive maintenance and segment control of pressure and temperature in the melding zone. Controlling the temperature in the melding zone has several advantages. As in the current state of the art, the heating bars may get excessively warm, affecting the quality of the melding process over time.

[0071] Various embodiments of the disclosure, as discussed above, may be practiced with steps and / or operations in a different order, and / or with hardware elements in configurations, which are different than those which, are disclosed. Therefore, although the disclosure has been described based on these exemplary embodiments, it is noted that certain modifications, variations, and alternative constructions may be apparent and well within the spirit and scope of the disclosure.

[0072] Although various exemplary embodiments of the disclosure are described herein in a language specific to structural features and / or methodological acts, the subject matter defined in the appended claims is not necessarily limited to the specific features or acts described above. Rather, the specific features and acts described above are disclosed as exemplary forms of implementing the claims.
