Definitions

  • the present invention relates to a universal heat seal tester. More particularly, the present invention relates to a method and apparatus for simulating heat-sealing processes.
  • the invention can simulate a hot-air side-seaming section of a cup machine.
  • U.S. patent No. 3,444,732 (Robbins) relates to a method and apparatus for determining optimum bonding parameters for thermoplastic material. Different heating temperatures are simultaneously applied through heated metal elements, which directly contact the substrate being tested.
  • the present invention is directed to a method and apparatus for testing heat-seals while simulating real manufacturing processes, specifically heat-sealing processes.
  • Another object of the present invention is to simulate a hot-air side-seaming section of a cup machine.
  • Yet another object of the present invention is to simulate other types of heat-sealing processes, such as ones relating to liquid packaging machines, which include electric, gas-fired, hot-air, induction, and radiant heating.
  • a further object of the invention was to reduce operator involvement, by implementing an automated test sequence.
  • FIG. 1 is a flow chart of a method according to the present invention.
  • FIGS. 2a-2d are schematic views of the steps of the method according to the present invention.
  • the 10 of the present invention employs two sample holders , a left and right sample holder 11 and 12, respectively, to clamp two samples 20 along two edges.
  • the samples 20 can be laminates such as opaque substrates, and can be paper, plastic, or foil laminates or a combination of those elements such as- pa ⁇ per/plastic laminate or paper/foil/plastic laminate.
  • Several pins may be positioned on the sample holders 11 and 5 12 so that they come close to the back sides of the two samples 20, and thus provide some support in the event that one or both of the samples 20 moves during the process.
  • the samples 20 are positioned so that the surfaces to be sealed are in face-to-face relation with one another, and so 0 that a gap exists between the two samples 20.
  • At least one movable heater 30 moves between the samples 20 to heat sections of the samples for preprogrammed lengths of time, as shown in Fig. 2a. In the illustrated embodiment two heaters 30 are shown. A staggered time difference for heating the two samples 20 may 5 be incorporated.
  • the heaters 30 are then withdrawn, and after a prepro ⁇ grammed delay the right sample holder 11 moves closer to the left sample holder 12, as shown in Fig. 2b.
  • the left and right sample holders 11 and 12 are then clamped together after a second preprogrammed delay, as shown in Fig. 2c.
  • the pressure at which the left and right sample holders 11 and 12 are clamped is adjustable.
  • the length of time the two samples 20 are clamped together is adjustable. Once that preprogrammed length of time has expired, the two sample holders 11 and 12 are separated as can be seen in Fig. 2d, and the two samples 20 are pulled apart after a programmable delay. The quality of the seal is then evaluated.
  • All of the time periods and delays, temperatures, air ⁇ flow rates and pressures can be varied to particular machine operating parameters.
  • the actual times, temperature, pressures, and delays can be monitored in real time by an operator, by , utilizing an operator interface and other indicting devices.
  • the time periods, temperatures, pressures, air flow, , sample size and/or configuration can be changed as desired.
  • the heater 30 does not come into contact with the samples 20.
  • the type and size of the heater 30 can be varied.
  • the heater 30 may be an electric heater, a gas-fired heater, an inductive heater or a radiant heater.
  • the present invention may incorporate a configuration where only one of the sample holders 11 and 12, or both of the sample holders 11 and 12 are movable towards one another. Furthermore, the invention is not intended to be limited to a single heater 30, but rather, any number of heaters may be employed. As a result of the method and apparatus of the present invention, realistic simulation of heater temperatures, heating times, air flows, clamping temperatures and pressures, and other time periods, important to the heating process, can be pro ⁇ grammed. An automated testing protocol may be used to eliminate operator dependence. The automated testing can continuously monitor the times, air flow, temperatures, and pressures.
  • sample holders can be moved by air cylinders, or by other comparable mechanical devices.

Abstract

Dispositif et procédés universels de test de thermosoudage (10) permettant de simuler des processus de thermosoudage. Ledit dispositif de test (10) comporte une paire de porte-échantillons (11, 12), chacun maintenant un échantillon (20). Un dispositif de chauffe (30) est placé amovible entre les échantillons (20) et selon la présente invention, il est possible de simuler une section de soudage latéral par air chaud d'une machine de fabrication de gobelets. Ledit appareil teste des thermosoudures entre les échantillons (20) tout en simulant des processus de fabrication réels, en particulier le processus de thermosoudage, et peut simuler d'autres types de processus de thermosoudage, tels que ceux relatifs à des machines d'emballage de liquides qui comportent une chauffe électrique, au gaz, par air chaud, par induction et radiante. Le procédé de la présente invention peut être appliqué automatiquement afin d'éliminer les variations dues aux opérateurs.
