Изобретение относитс к технологии упаковочно-фасовочного процесса.This invention relates to a packaging and packaging process.
Известен способ регулировани процессом термоусадки пленки при упаковке в нее изделий, заключающийс в измерении физического параметра нагрева пленки 1. s При осуществлении этого способа изделие помещают в чехол из термоусадочной пленки, сваривают край рукава и подают в термоусадочную камеру, где под действием температуры в течение заданного времени пленка усаживаетс и плотно обт гивает изделие. There is a method of controlling the shrinking process of a film when packing products into it, which consists in measuring the physical parameter of heating a film 1. When this method is applied, the product is placed in a sheath of shrink film, the sleeve edge is welded and fed to the heat-shrink chamber where time the film shrinks and tightly wraps around the product.
Регулируемыми параметрами способа вл ютс температура и продолжительность нагрева, котйра задаетс реле времени.The adjustable parameters of the method are the temperature and duration of heating, the temperature is set by the timer.
Недостатком этого способа вл етс получение упаковок нестабильного качества. Это объ сн етс тем, что в процессе управлени способом не учитываютс случайные факторы, а именно: изменение наружной температуры среды; колебание теплофизических свойств усаживаемого материала и упаковываемого издели и т. д.20The disadvantage of this method is to obtain packages of unstable quality. This is due to the fact that in the process control method random factors are not taken into account, namely: a change in the outdoor temperature of the medium; fluctuation of thermophysical properties of the shrinkable material and the packaged product, etc.
Вли ние случайных факторов снижает надежность регулировани процессом.The effect of random factors reduces the reliability of the process control.
Целью изобретени вл етс повыщение надежности регулировани .The aim of the invention is to increase the reliability of regulation.
Поставленна цель достигаетс тем, что при осуществлении способа регулировани процессом термоусадки пленки при упаковке в нее изделий в качестве физического параметра используют измен ющуюс в процессе термоусадки толщину пленки, величину которой определ ют при помощи датчика, установленного у поверхности пленки.This goal is achieved by the fact that during the process of regulating the shrinking process of the film during the packing of products into it, the physical thickness of the film used during the shrinking process is determined.
Способ осуществл етс следующи.м образом .The method is carried out as follows.
На поддоне формируют пакет из упаковываемых изделий, сверху на него нат гивают рукав из полиэтиленовой термоусадочной пленки, нижние концы рукава закрепл ют на торце поддона, а верхний конец сваривают, например термоимпульсной сваркой . Затем пакет на транспортере подаетс в термоусадочный шкаф, где в соприкосновении с поверхностью пленки устанавливают датчик, который входит в систему управлени движением транспортера и измер ет толщину пленки.A bag of packaged products is formed on the pallet, a sleeve of polyethylene heat shrinkable film is pulled on top of it, the lower ends of the sleeve are fixed on the end of the pallet, and the upper end is welded, for example, by thermo-impulse welding. The bag is then conveyed to the conveyor in a heat shrinkable cabinet, where, in contact with the film surface, a sensor is installed, which is included in the conveyor motion control system and measures the film thickness.
