Definitions

  • the present invention relates to the field of making sheath sections of heat-shrinkable plastic and intended to be placed and then shrunk hot around containers. It relates more particularly to a new apparatus allowing the production in contunu, at high rate, of such sections or sleeves from a continuous strip of flat sheath as well as the conformation of these sleeves to the types of containers to be coated and then their automatic laying around of these containers.
  • the plastic film is made of a sheath or continuous sheath and then sections of sheath are cut to the appropriate demensions and the sleeves obtained, stacked horizontally or vertically in a store, are used to feed a machine allowing individually extract the sleeves then open them to the desired shape and place them around the receptacles to be coated which circulate on a conveyor, the covering then being subjected to heat shrinkage (see for example French patent No. 2,355,719 of February 1976 and its certificates of addition No. 2,369,971, 2,376,794 and 2,395,897).
  • the invention aims to remedy these various drawbacks and aims to produce and install, at high speed, sleeves already having the general shape of the containers to be coated. It offers, for this purpose, an automatic apparatus which directly uses as raw material the continuous flat sheath of plastic film and not stacks of sheath sections and which performs the series of operations of: shaping, cutting, guiding and laying the sleeve, along a vertical line overhanging the series of receptacles which run on a conveyor.
  • the improved machine is of the general type described above, but it is essentially characterized in that: a / it comprises means for removing the two folds of the flat sheath, before cutting of the latter, b) the cutting means are arranged around the mandrel and not above it; and c) it contains, under the cutting means, stepped means allowing automatic adjustment of the heights and cutting rates.
  • thermoplastic flat sheath is subjected to a precut operation before being engaged around the tapered upper part of the hollow mandrel.
  • This operation which can be carried out for example by means of a sawtooth blade penetrating into a counterpart made of rubber, makes it possible later to obtain a sharper and faster cut.
  • the means of unfolding the sheath, just after the engagement of the latter around the mandrel, are constituted by jaws heated by any known means (electric, hot air, infrared, etc.) and whose contact time with the sheath on the mandrel is programmed in sequence with the cut and according to the temperature (generally between 70 and 120 ° C). These jaws can be controlled by any known means with an alternative function.
  • the means for cutting the sheath into sections or sleeves can advantageously be constituted by a rotary device provided with horizontal blades, for example two which penetrate into the sheath when they are already in rotation.
  • a rotary device provided with horizontal blades, for example two which penetrate into the sheath when they are already in rotation.
  • other equivalent cutting systems such as cutting jaw device, cutting ring or the like, can of course be implemented.
  • the means for guiding the sheath on the mandrel are constituted on the one hand by rollers or rollers with alternative control and on the other hand by lug chains controlled by the camshaft.
  • the descent of the cut section of sheath and then its expulsion at the bottom of the mandrel are facilitated by sending, within this hollow mandrel and provided with microperforations preferably oriented downward, air or any other slightly pressurized fluid. This injection of fluid is triggered automatically after the cutting operation and is advantageously carried out at two points on the hollow mandrel, under different pressures.
  • the flat sheath is strongly pulled in tension by the cylinders 9 and then it is released by means of a flexible interlocking system 10 passing in front of a photoelectric cell 11; a sheath reserve is thus created during the subsequent cutting operation and the cell makes it possible to re-tension the sheath in order to deliver a new length of section to the assembly 3.
  • the drive of the continuous strip up to the top of the assembly 3 takes place between series of rollers or rollers 12 driven by the motor 13.
  • this single motor controls the series of clutch-brakes provided for the operation of the moving parts of the machine, as well as the camshaft for controlling the elements of each vertical assembly.
  • the sheath 8 After its engagement, at the start of unwinding of the coil 6 around the head of the mandrel, the sheath 8 is subjected to operations of: unfolding, cutting, transfer and fitting of the sleeves around the receptacles to be dressed, all these operations being carried out in synchronism, as will be seen below, in each of the vertical assemblies generally designated by the number 3.
  • the sheath After unfolding, the sheath is subjected to cutting 18 for example using a rotary device with blades, designated by the number 18 on the Figures 1 and 7, which is also driven by the motor 13 and the blades of which penetrate the film when they are already in rotation.
  • a rotary device with blades designated by the number 18 on the Figures 1 and 7, which is also driven by the motor 13 and the blades of which penetrate the film when they are already in rotation.
  • this cutting device a microperforation system intended to create in a given area of the sheath an additional pre-cut line.
  • a photoelectric cell (not shown in the figures) is installed which makes it possible to determine the appropriate length of each section of sheath.
  • the machine is installed above a conveyor 4 intended for the continuous feeding of the containers to be sleeved.
  • a conveyor 4 intended for the continuous feeding of the containers to be sleeved.
  • Such a belt conveyor without end is provided with a heating tunnel 5 intended to heat-shrink the sleeves around the containers brought by the conveyor and covered by a vertical assembly 3.
