Definitions

  • the present invention relates generally to the art of bag making. More specifically, it relates to pouch-type bag making.
  • Pouch machines may have continuous or intermittent motion, and have a generally horizontal or vertical machines film path. In either case a continuous web of material or film is converted into a series of individual pouches. Generally, the continuous film is folded in half over a plow or forming shoulder. The folded web is transported through at least one cross-sealer, which has seal bars in the cross-machine direction, to form cross seals, thus creating a strip of pouches interconnected by transverse seals (and open opposite the fold). A cut-off unit separates the continuous film into individual pouches by cutting each cross-seal. Individual pouches are subsequently filled and sealed at a separate machine.
  • Prior art intermittent motion pouch machines alternately advance the film, and then the various processing stations process the film when it is stationary (the dwell time).
  • Examples of such pouch machines include U.S. Patent No. 5,181,365 and 6,195,967 (hereby incorporated by reference).
  • Pouch machines perform a number of processes in addition to the sealing and cutting described above that form the pouch, such as forming a zipper seal (or weld) on a film, forming a long seal (machine direction) on the film, and applying a "slider" closure on the film.
  • One or more of these processes, along with feeding/folding the film, forming cross-seals, and separating adjacent pouches are performed in succession, and, depending on what process are performed, any of a variety of pouch style may be made.
  • the machinery performing the processes are housed in a single structure (called a cab or cabinet).
  • a single controller controls the entire process and all of the needed machinery.
  • the controller is typically housed in a separate structure.
  • Such a pouch machine has one common electrical control cabinet housing the complete electrical requirements for the complete specialized machine line. This makes for an inflexible, limited product range machine, and its expensive to change product styles.
  • a pouch manufacturer desires to make a particular style pouch
  • the machinery needed to perform the required processes is determined, and a specialized machine, including a controller, is built. If the pouch manufacturer desires to make a different style pouch a new machine must be built, or the existing machine must be disassembled, and then rebuilt with the appropriate machinery and controls.
  • Another type of prior art pouch machine provides for modules which each house machinery for a specific task, rather than a single cab.
  • a single central controller is provided to control each of the various modules. Changing pouch styles requires changing modules, and rewiring of the controller, and possibly a redesign of the controller so that it can control the new modules.
  • Pouch machines are typically 30 or more feet in length due to the great number of processes that have to be done to the web.
  • the film or web is drawn through the machine by a single drawroll assembly.
  • the drawroll is registered to a registration mark on a film.
  • An example of such a prior art machine is found in US Patent No. RE 35,067, hereby incorporated by reference.
  • Some prior art machines have dual drawroll systems, such as that described in US Patent No. 5,086,964 (hereby incorporated by reference). Such a system uses one drawroll for registration and the other drawroll for advancing the web and setting web tension between the drawrolls.
  • prior art pouch machines provide that the machinery or tooling that performs the process on the web (cross sealing, punching, die cutting, etc.) are each on an independent carriage that is moved to the position of the stopped web to accurately register the process to the web, film, mark, seal, etc.
  • a pouch machine that does not require processing devices to be moved along the machine direction for proper registration is desirable.
  • Pouch machines in the prior art includes web guides.
  • Such guides were developed for use with continuous motion machines and the guides were separate from the rolls drawing or driving the film or web.
  • the web guides were needed because the web often tracked toward one side of the machine or the other. This may be caused by mis-alignment of drawrolls, sections of the machine being out of proper alignment with each other, material which is thicker on one edge of the web than the opposite edge or stretched material. Whatever the cause, it is important to keep the web tracking properly through the machine.
  • Figure 3 shows such a prior art web guide system that includes guide roller or rollers 320 moving in a lateral and angular direction. This movement steers the web laterally into the entering span 321 of the drawrolls 309.
  • the guide is mounted on slides or bearings 322, with a point of rotation 323. While this technology may be better than other prior art web guides, it was developed for a moving web, it has several shortcomings when applied to an intermittent machine such as a pouch machine such as locating the nips (from guide rolls 320) in or near the longitudinal sealer section, the web is not guided properly in intermittent motion, and it requires additional framework and additional rack and rail length is required.
  • a pouch machine includes a controller and first and second modules. Each module has a converting station and the electrical equipment needed to operate the station. The controller controls the converting stations. The first module further has an operating parameter input connected to the controller and an operating parameter output. The second module has an operating parameter input, connected to the operating parameter output.
  • a pouch machine has a plurality of modules.
  • Each module includes a converting station and is electrically self-contained.
  • the modules are configured in a daisy-chain. Successive modules receive operating parameters from the preceding module.
  • a method of making a pouch machine includes selecting two modules. Each module has a converting station operatively connected to a central controller. An operating parameter output is provided from the first module to the second module.
  • a third module including a converting station, may be connected to the second module, wherein operating parameters are received by the third module in one embodiment.
  • the first module have an infeed station
  • the second and third modules have converting stations that are one (not necessarily the same one) of the group consisting of a zipper sealer station, a long sealer station, a cross sealer station, a cross seal extension station, and a slider station
  • a fourth modules may have a cut-off station.
  • a common user interface for a central controller is provided in another alternative.
  • a pouch machine includes two processing zones. Each has a first station along a film path, a registration sensor along the film path, and a drawroll. Each drawroll is responsive to the respective registration sensor.
  • the sensor is an optical sensor that detects print registration marks in one alternative.
  • the processing stations are at fixed locations in another embodiment.
  • Accumulators are included in each processing zone, and the machine includes a third processing zone that does not have a draw roll in various embodiments.
  • a pouch machine includes a plurality of processing devices.
  • An edge sensor senses the edge of the film.
  • a draw roll assembly is mounted on a moveable frame, and is angled in response to the location of the sensed edge. Multiple such assemblies may be included on a single machine.
  • One aspect of the invention relates to a modular design of a pouch machine converting line.
  • the machine is comprised of several free standing, mechanically and electrically self-contained modular sections.
  • Electrical self-contained includes a module that has the electrical equipment needed to operate the module, although not necessarily the controller.
  • Each section is designed to plug in and produce a unique pouch product.
  • This fast, flexible, "plug and play", building block approach allows for the converting of multiple pouch style products from a single base machine. It also increases the versatility of the base machine to economically adapt to different products in changing markets.
  • the invention eliminates the common main cabinet by providing individual cabinets containing all the electrical that is required for that specific modular section of machine.
  • the overall machine line is then controlled through fiber optic wires between modules and to the PC based operator interface - the controls are daisy chained.
  • Registration sensor includes a sensor that detects a seal or registration mark on a film, bag or pouch, and may include circuitry, digital and/or analog and hardware and/or software that provides a signal indicating the location of the registration mark, seal, or pouch.
  • This reduces or eliminates the need for processing devices to be mounted on carriages. This may be combined with the modularity aspect, or implemented separately.
  • Another aspect of the invention provides for having the drawrolls cooperate with an edge sensor, such that the draw rolls are both drawing the film and guiding the film.
  • the drawrolls are mounted on a moving frame, and are moved to a desired angle to guide the film in a desired direction (in response to the edge sensor). This aspect may be combined with the other aspects, or implemented by itself.
