Definitions

  • the present invention refers to a heat seal packaging device for covering (by heat sealing) openings of containers containing packaged items with a capping film.
  • a heat seal packaging device for covering openings on containers containing packaged items with a capping film, and heat sealing procedure.
  • Capping film for the contours of containers and for packaging is already known (e.g., see Patent literature 1).
  • Information such as date of production is also printed on the capping film at a position corresponding to each container containing the packaged item by a printing means.
  • the printer printing head
  • the capping film is moved to a set angle to be able to print on the capping film in use.
  • the printer (printing head) of the heat seal packaging device is permanently positioned, whilst the capping film is being fed across the container transferring part, containing the packaged items and the beat seal mechanism part for heat sealing the opening areas of the containers, the capping film is fed at a set angle to print the film.
  • the transferring speed of the container transfer part is synchronized with the printing speed of the printer with the feeding speed of the capping film.
  • the feeding procedure of the capping film is stalled. In this way, the film cannot be printed during the heat sealing process.
  • any of the system that the speed of each step of the heat seal processing is increased to increase a processing speed of the entire device, or a system that multiple containers to be heat sealed by batch processing to improve productivity is utilized.
  • the feeding speed of the capping film also increases, which results in a problem that the printing speed of the printer (printing head) positioned and arranged in a set position fails to maintain the same speed as the capping film and therefore the printing quality is bad (e.g. smudged or faded characters). Therefore, the speed of the capping film or a printing duration of the printer or similar is restrained, so the increased processing speed of the entire device and the heightened productivity are limited.
  • the present invention has been created in light of problems with the previous model, and the object of the present invention is to provide a heat seal packaging device which prints information on the capping film which covers the opening areas of containers and heat seals the containers, maintaining quality printing on the capping film and improves the productivity and speed of processing a of the entire device.
  • the object of the present invention as a technical means is to , heat seal multiple batches of containers which are collectively transported in batches, the information is then printed on the capping film covering the opening areas of the containers used to heat seal the group of containers to be heat sealed, when a set number of containers are heat sealed by the printed capping film. Therefore the required time, per cycle of packaging can be reduced.

  • the printing means prints information of the packaged items on the stationary capping film covering the opening area of the container to be consequently heat sealed, whilst the heat sealer downstream of the packaging line is beat sealing the capping film to the containers
  • the number of containers to be heat sealed at each time is not particularly limited, but the number of container supply means, heat sealer and container transport means have to be identical. Also, to reduce the length of the entire device, multiple rows (for example, two or more rows) are more effective than a single row, set in the same direction as the containers.
  • the packaging line refers to a moving line of the container from the container supply means to the heat sealing means.
  • the printer printing the information of the packaged items on the capping film can use any sort of printing methods, for example, a thermal transfer type for printing the information by applying heat to an ink ribbon with a thermal head, or an inkjet type.
  • the mechanical means moving the printer along the packaging line has, for example, a structure with a continuous rotary belt and a gear; or a structure containing a rack and pinion, and any other structure which can return to a set zone.

Therefore, the relevant information of the packaged items corresponding to the containers held by the container supply means can be printed on to the capping film.

  • print information of the capping film supplies not only the information of the packaged item of a established amount, but also information such as the weight of the packaged item of a non-established amount can be indicated. Then, the printer moves toward the starting end using a terminal end of the container supply means as a starting point, and then returns to the starting point position when the information has been printed to of an established amount of containers, and therefore, the information of the packaged items can be definitely printed on the capping film whilst maintaining a correlation to the packaged items contained in the containers.
  • a printer prints information of packaged items on a capping film whilst a heat sealer heat seals opening areas of the containers with a capping film, so that the information can be clearly printed on the capping film, and a processing speed of the entire packaging device can be increased without delaying a series of processing speeds of heat seal packaging to improve productivity.

If the weighing procedure of the packaged item is faster than the printing procedure the merchandise information on the capping film I, the measuring information is stored in a memory ,and is not linked to the weight as a procedure, but by the programmed merchandise information and therefore is printed on the capping film matching the relative batch unit.
  • the containers for the next batch are aligned and held on the container supply means A on the upstream side, and the merchandise information of these (seventh to twelfth) containers is sequentially printed (as indicated) on the print area 17 of the capping film 1 on the container supply means A at the same time.
  • the lower seal mold B1 and the upper seal mold B2 of the heat sealer are carried out and the heath seal packaged containers supported on the lower seal mold B1 and the containers for the next batch aligned and held on the conveyor of the container supply means A are moved by the container transport means B which are then transported to the unloading conveyor 15 at a downstream position, and the containers for the next batch aligned and held on the conveyor of the container supply means A are transported on the lower seal mold B1 of the empty heat sealer B, from which the packaged containers are moved.
  • the heat seal packaged containers are cut off from the capping film 1 by heat cutting (or a cutting blade), and a residue (outer peripheral portion) of the capping film 1, from which a heat seal portion is cut off, maintains its longitudinal continuity, and is moved by one batch by driving the film take-up part C2 of the capping film supply means C.
  • the heat seal packaging device aligns and holds a predetermined number of containers on a conveyor of a container supply means to form a batch form, and moves the printer to print the film whilst the capping film is interrupted. Therefore, the capping film can be printed without compromising the printing quality.
  • the merchandise information is printed on the capping film during the heat seal packaging process of the previous batch container, and the packaged containers are unloaded from the heat sealer, and the next batch containers aligned and held on the heat sealer after unloading, the containers are contemporarily moved parallel, therefore, efficiently enabling a series of cycles, such as printing, packaging and unloading
  • the heat seal packaging device according to the present invention is not limited to the illustrated structures, and modifications can be appropriately/ custom made without compromising or altering the present invention.
