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 continuous production, at high speed, 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 from a continuous sheath or sheath and then sections of sheath are cut to the appropriate dimensions and the sleeves obtained, stacked horizontally or vertically gasin, are used to feed a machine making it possible to individually extract the lugs then to open them to the desired conformation and to deposit them around the receptacles to be coated which circulate on a conveyor. the covering then being subjected to heat shrinking (see for example French patent N ° 76.05033 of February 24, 1976 and its certificates of addition N ° 76.33691, 77.00209 and 77.19565).
  • the object of the invention is to remedy these various drawbacks and is aimed at the production and fitting, at high speed, of sleeves already having the general conformation of the containers to be coated.
  • it proposes an automatic apparatus which directly uses as raw material. the continuous flat sheath of plastic film and not of the stacks of sheath sections and which performs the series of operations of: shaping, cutting, guiding and fitting of the sleeve, according to a vertical line overhanging the series of receptacles which pass on a conveyor .
  • the supply of flat sheath of the vertical assembly designated by b) is made by means of a closed package containing one or more sheath coils and provided with a horizontal slot allowing passage to the continuous strip.
  • This strip first subjected to strong traction is then released to allow subsequent adjustment of a predetermined cutting length and then it is again stretched over said vertical assembly.
  • all of the operations carried out on the sheath are carried out around a hollow carrier mandrel whose saction corresponds to the configuration desired for the final sleeve.
  • This mandrel is carried by horizontal platforms delimiting several stages and provided with retractable lugs intended to engage in grooves provided on the mandrel.
  • thermo-plastic 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, allows a sharper and faster cut to be obtained subsequently.
  • 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 a device, with sharp jaws, cutting ring or the like, can of course be implemented.
  • the steps which follow the cutting means are preferably three in number and essentially have the function of ensuring the lift and the centering of the mandrel during the cutting of the sheath then the descent and expulsion of the sleeves.
  • the actions of these different levels are carried out in sequence, in particular by means of a central camshaft, in such a way that there are always, during the running of the machine, two open levels (that is to say released from the mandrel) and a closed level (platform blocking the mandrel) or vice versa.
  • 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 sheath section 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.
  • this frame can support several cutting assemblies designated above by b) for example two, three or more.
  • the machine essentially comprises: a magazine 1 for supplying a flat sheath of thermoplastic film; a system 2 for winding and distributing this sheath; one or more vertical assemblies 3 (the machine shown contains three) intended for cutting the sheath then for guiding and laying the sheath sections around containers; finally a series of means for transmitting the movements of the various members as well as means for controlling the movements of transfer and opening-closing of the stages of each vertical assembly.
  • the machine is installed above a conveyor 4 intended for the continuous feeding of the receptacles to be coated and provided with a device 5 for hot shrinking of the sleeves after their removal around each receptacle.
  • the magazine 1 is advantageously constituted by a parallelepedic box, for example made of cardboard, in which there are arranged vertically side by side, separated by spacers, for example two coils 6 of plastic sheath wound flat as obtained by welding. continuously from two close edges of a heat-shrinkable plastic film such as, for example, polyvinyl chloride.
  • the sheath can, of course, be provided with any prints and decorations according to known methods. One coil is kept in reserve while the other is used to power the machine.
  • the packaging is provided with a slot 7 and the sheath 8 follows, as can be seen in FIG. 4, a path along which it is subjected to different tensions. At the start, the flat sheath is strongly pulled in traction by the cylinders 9.
  • thermoplastic sheath 8 When the thermoplastic sheath 8 passes over the upper part of the assemblies 3, it can be subjected, if desired, to a pre-cutting operation before being engaged around the tapered head of the hollow mandrel 14.
  • This operation which can be practiced, for example, using a sawtooth blade penetrating into a counterpart in rubber, .allows you to obtain a more frank and faster cut of the sheath in sections.
  • 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 mandrel 14 which can have any shape, for example cylindrical, is constituted by a hollow element, made of plastic, metal or alloy, the wall of which is provided with microperforations intended to let escape a flow of air or other blown fluid inside.
  • This mandrel 14 is permanently maintained and adjusted in the vertical position by at least one of the platforms 23,25,28.
  • a platform (example: 23) is provided with several studs 32, actuated by springs 33 or other means, these studs being received in a groove or groove 34 provided on the periphery of the mandrel 14.
  • the mandrel can be held at least at one of the platforms 23,25,28 by a jaw adapting to an appropriate housing of the mandrel.
  • this sheath is driven in its descent on the mandrel 14 by the rollers 16 actuated by the clutch-brake 35 connected to the camshaft, this sheath is subjected to unfolding by means of the heating jaws 15 formed, for example , by two metal half-shells internally coated with a plastic material (silicone rubber or the like) intended to avoid any possible local overheating. Thanks to their constitution, these two shells join together on the mandrel 14.
  • a plastic material silicone rubber or the like
  • the sheath After unfolding, the sheath is subjected to the cut 18 for example using a rotary device with blades, designated by the number 18 in Figures 1 and 7, which is also driven by the motor 13 and whose blades penetrate in the film when they are already rotating.
  • a rotary device with blades designated by the number 18 in Figures 1 and 7, which is also driven by the motor 13 and whose blades penetrate in the film when they are already rotating.
  • .on can be added to 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.
  • a chain 22 is provided on each side of the mandrel 14 provided with a lug or projecting finger 36 (see FIG. 6) and which, controlled by the camshaft 20, accompanies the progression of the sleeve 37 downwards, the movement of this chain being synchronized with the opening and closing operations of the stages.
  • the mandrel When the sheath 8, possibly pre-cut, has just been threaded onto the mandrel 14 (start of the coil), the mandrel is held in position by closing the studs 32 provided on the platform 28 of the lower stage ( rest position).
  • the platforms 23 and 25 are open while the platform 28 is closed; the roller systems 16 are set in motion to lower the sheath over the length of cut to be made.
  • the electromagnet cell (not shown) causes the shutdown. of these rollers and controls the unfolding operation at 15, then initiates the cut at 18.
  • the end of cut detected by a counterfeiter, triggers the rotation of the rollers 21, 'of the camshaft 20 and the accompanying chains 22 of the sheath section.
  • the camshaft rotates, closes the stage 23 and opens the stage 25.
  • the chain 22 ensures the passage of the sheath section to the stage 25.
  • the camshaft 20 continues to rotate then it ensures the closing of the stage 25 and the opening of the stage 28.
  • the sheath section then continues its course until the lug chain 22 has expelled, with the support of the air pressure sent through the pipe 26, the sleeve outside the hollow mandrel 14.
  • the lower stage 28 closes while the upper stage 23 opens and the cycle begins again in the order indicated above.
  • the machine is installed above a conveyor 4 intended for the continuous feeding of the containers to be sleeved.
