Disclosed is a hygienic clamp attachable to conveying chains used in horizontal, form, fill, and seal, packaging machines. The clamp is used for holding the packing film, which is conveyed between various work stations of the machine. The clamp assembly comprises of three components: stanchion, gripper, spring. The clamp eliminates the use of a rivet, previously used for holding the spring, and guiding vertical moment of the gripper during the clamping process. The hygienic clamp replaces the rivet with a mortise and tenon connection. The mortise is located inside the stanchion and the tenent is located inside the gripper. The hygienic clamp also incorporates a ridge (attached to the stanchion) which interacts with the tenon (protruding from the gripper). The interaction between these two parts enables delayed closure of the clamp, independent of the cam's actions, which functions as the primary opening and closing mechanism for the hygienic clamp.

Disclosed is a device for mounting and unspooling a packaging film roll. The device is attached to a horizontal, form, fill, and seal packaging machine. The film is used to form the bottom portion of packages made by the machine. The device comprises of a shaft, sleeve subassembly, air chuck, adjuster subassembly, internal and external housing subassemblies, brake, and film roller subassembly. The sleeve subassembly along with the chuck is used for holding the packing film roll. The adjuster subassembly is used to aligning the packaging film roll with the machine's conveying chain. The conveying chain pulls the film into the machine, resulting in unspooling of the packaging film roll. The brake is used to controllably stop and restart the unspooling of the film roll, which allows the film roller subassembly to keep the packing film entering the machine is flat and properly tensioned.

Disclosed is a packaging film perforating system used in commercially available, horizontal, form, fill and seal packaging machines. The packing film perforating system is attached to a packaging machine via a mounting module. The system is designed to create perforation lines in the packaging film, housing pre-packaged product, being moved by a conveying chain between various functional stations located on said packaging machine. The perforating system is positioned as the last automated station of the packaging machine, and is typically preceded by a plurality of other automated stations designed to fully complete the packaging process. The stations preceding the location of the perforation system may include stations designed to feed both the bottom and the top layers of the packaging film, product fill station, and both the bottom and the top package forming stations. The packaging film perforating system comprises of four primary modules: 1) perforating module assembly, for perforating the packaging film; 2) mounting module assembly, for mounting the perforating module to the machine and for enabling rotation of said perforating module; 3) packaging machine, having a package perforation station for placing therein the perforating module, held by the mounding module; 4) and a plurality of mounting hardware, used for completion of said assemblies. The perforating module assembly is sub-divided into two components: 1) shaft; 2) perforating disc sub-assembly. The perforating disc slides onto the shaft, and is releasably locked in place. The shaft may hold one or a multitude of the perforating discs. Spaces between said perforating disc may be adjusted to accommodate various shapes and sizes of the packaged products. Each perforating disc comprises of a back disc, a front disc, and a plurality of knives. Wherein each of said knives has one blunt edge and one sharp edge. The knives are configured to be equally spaced, with all blunt edges facing in the same direction, and are positioned around the outside perimeter of the two discs. The knives are sandwiched between the two discs, locked in place, made to extend beyond the two discs' outside perimeter. The perforating module is held by the mounting module, by having both ends of the shaft fitted inside bearings, held by two bearing blocks. Using actuators, the bearing blocks along with attached thereto perforating module, are moved up and down, allowing the perforating discs to engage or to disengage the packaging film, located directly below the mounting module. Once engaged, the conveyed packaging film pushes on the blunt edge of the knives, causing the perforating disc to rotate, without application of any external power. The rotation of the perforating disc generates equally-spaced, elongated cuts in the packaging film, forming perforation lines, outlining the ends of the created packages.

Disclosed is a cross-cut stabilizer. The stabilizer prevents uncontrollable movement of the existing cross-cut stations, which are used in packaging machines to make long cuts designed to separate a strip of multiple, pre-packaged products from the rest of the packaging film. The movement created by the machine's vibration, causes the cutting blocks, along with the blades making the cross-cuts, to move unpredictably. The movement is compounded by the rack and pinion system which supports the cutting blocks of the cross-cut station. The cross-cut stabilizer, incorporates a mounting base, which holds pushing combs and manual clamps. The stabilizer is mounted inside the cross-cut station, allowing the pushing combs to straddle the existing cutting blocks. The pushing combs enable unison, manual adjustment of the cross-cut station with the cross-cut stabilizer. By using clamps, the pushing combs urge down on the cutting blocks of the cross-cut station, eliminating any movement of the station.

A transport indexing chain for a food-packaging machine is made of two different materials in order to provide the most optimal result of a drive chain that resists wear and tear and thus reduces elongation of the chain over time, and which also provides a drive indexing chain that resists bacterial infection. In order to satisfy the first objective of providing a chain that resists wear and elongation of the drive chain, the parts thereof that remain exposed to greasing or lubrication, and thus are resistant to rusting, are made of the same prior-art material of nickel-plated carbon steel. These parts are: The bushings, the rollers, and the pivot rods or pins. The remaining parts, namely the links or side plates and the clamping attachments, are made of stainless steel, whereby prevention of bacterial infection is substantially achieved without increased wear.

An improved indexing vacuum-packaging machine more accurately positions and aligns the upper film relative to the lower film at the sealing station. A video camera replaces a conventional photocell, whereby the braking and concomitant stretching of the upper film at the sealing station need only be performed only every few indexing cycles, whereby shaking and jerking of the machine is negated as compared to a conventional vacuum-packaging machine. The video camera may use any portion of the printed matter on the upper film as a target for determining when to brake the upper film for the subsequent stretching thereof, without having to rely solely upon the hithertofore-used one black target-box imprinted on the upper film. The video camera is focused on a section of the portion of upper film at the sealing station for detecting a predetermined target area of printed matter, which section to be detected may form any part of the printed matter, and is not limited to, and preferably not, the one black target-box located longitudinally centrally between each longitudinally repeating pattern of printed matter on the upper surface-face of the upper film. When the target image-area has been detected by the video camera apparatus and the software thereof, an output signal is generated to cause the braking mechanism of the vacuum-packaging machine at the sealing station to be actuated to brake the upper film that will stretch the upper film.

An improved sealing gasket for a vacuum-sealing station of a vacuum packaging machine which is made such that the outer perimetric portion thereof is made of a greater hardness than the rest of the sealing gasket, whereby the sealing heat-elements of a reciprocal heating element only substantially contacts against the softer material of the sealing gasket, allowing this softer material to conform to the uneven or non-level condition of the heating element. In the preferred embodiment, the outer-most perimeter of the sealing gasket is made of a greater hardness in the approximate durometer-hardness range of between 60-85 Shore A, while the remainder of sealing gasket is made of less hardness in the approximate durometer-hardness range of between 30-50 Shore A.

A vacuum-packaging machine is provided with a drive mechanism for each of the tools at the forming and sealing stations that not only vertically reciprocate the tools, but which also horizontally reciprocate the tools. Before the next section of the film being processed reaches the forming or sealing station, the respective tool at each station is moved in the same direction as the film, while being simultaneously lifted up toward the film. As that section comes to a halt at the station, the tool is already raised into close juxtaposition to the film for performing its work. The tool is then raised the final quantum amount in order to start either the forming or the sealing process. As soon as the forming or sealing process has been completed, both the conveyer chain and the tools are actuated for forward, downstream movement. The tools, in addition to their forward, horizontal movement, also drop down, in order to clear the packages to allow unobstructed passage of the film.

A dual-section nozzle-head for use in a vacuum-packaging machine. The first section of the nozzle-head is provided with an interiorly-located manifold, that fluidly connects a series of first orifices, the exit-ends of which are located at the tip of the nozzle-head, so that these orifices may be fluidly coupled to the interior of packages at a sealing station of a vacuum-packaging machine for evacuating the packages via a vacuum source to which the orifices are connected. Interspersed between these first orifices are second orifices, which also have their exit-mouths at the tip of the nozzle-head. The second orifices are spaced apart, one from the other, along the length of the nozzle-head, and are coupled to a second manifold that is positioned exteriorly of the housing of the nozzle-head. The second manifold is coupled to a supply of protective inert gas.
