Definitions

  • the present invention essentially relates to a method of manufacturing a cardboard tubular cylinder and a machine for implementing this method.
  • the invention relates more specifically to a method of manufacturing a cylindrical and tubular body made of cardboard for fats in particular used for the packaging of solid or liquid product.
  • the paper is unwound from a reel and is brought onto the mandrel so that the transverse edge of the front end of the paper strip is in abutment against a limit switch situated under the mandrel.
  • the actuation of this switch by the paper strip controls the application of the paper to the mandrel and its winding around it.
  • it In order not to soil the mandrel with glue, it first coils a first layer of unglued paper on a lathe and a certain length of security.
  • a cam secured to the mandrel actuates a switch for putting the gluing device into service so that once the turn is completed, the glued paper arrives in the vicinity of its point of tangency with the mandrel.
  • the winding of the paper is continued to obtain the desired thickness of the cylinder; the rotation of the mandrel, the cutting of the paper being controlled and controlled by revolution counters of said mandrel.
  • This known method has a main drawback which resides in the imprecision of the command for implementing the device for gluing the strip of paper. Indeed, the positioning of the paper strip by the stop or the limit switch, located under the mandrel is very imprecise because of the great flexibility of the paper strip which is a function of its flexibility and speed scrolling paper. The variations in positioning of the paper sheet are of the order of approximately 100 mm. This imprecision causes a delay in the actuation of the stop, hence a risk that the glued side of the paper comes into contact with the mandrel.
  • the main object of the present invention is to remedy this drawback by proposing a manufacturing method making it possible to trigger the implementation of the gluing device with precision and thus eliminate the presence of the tongue and therefore save time and material. .
  • the subject of the invention is a method of manufacturing a cardboard tubular cylinder such as a barrel body by winding a strip of paper, for example of paper used in particular for packaging and known under the trade name of Kraft paper, or the like, in several layers on a mandrel, of the type consisting in winding a layer of paper tape on said mandrel, then in continuing to wind up said paper strip after having previously glued the face of the strip of paper of the following layers oriented towards said mandrel, to cut said strip of paper after the number of desired layers has been wound up, and to remove said cylinder thus produced and then repeat successive manufacturing cycles, characterized in that consists in measuring and controlling the length of the strip of paper unrolled at least at the start of each manufacturing cycle, and in triggering the abovementioned gluing operation on one face of the strip of paper when the length m measurement of unrolled paper reaches a reference value, so that at the start of each manufacturing cycle a length of unglued paper equal to or slightly greater than the perimeter of the mandre
  • the strip of paper is brought to the mandrel at the start of each manufacturing cycle by an intermittent automatic drive with timed control.
  • the present invention also relates to a machine for implementing the method described above, of the type comprising a paper feed reel, rollers for arranging the paper strip on a cylindrical mandrel such as a drum, cylinder or the like, said mandrel comprising means, for example a pneumatic nozzle or the like, for applying and maintaining at least part of the first layer of paper mentioned above on its surface, a counter-roller coming into contact with said mandrel to ensure winding of the paper sheet, a device for cutting the paper strip, means for prior gluing of the face of the paper facing the mandrel and means for controlling the number of turns of the mandrel to control the driving of the same -ci and / or the cutting device, characterized in that it further comprises means for detecting and measuring the length of paper unrolled at the start of each manufacturing cycle and means for c command controlled by these measurement and detection means to periodically issue a command signal for the implementation of the means of the aforementioned sizing.
  • a machine for implementing the method described above
  • the aforementioned means of detection, measurement and control consist of an electronic system preferably comprising a photoelectric member with slotted discs, for example.
  • the aforementioned measurement and detection means are mounted before the aforementioned gluing means in the direction of travel of the unwound paper strip.
  • the machine comprises a timed electronic control system, preferably with adjustable timing, for driving the aforementioned arranged rollers of the paper on the cylinder.
  • the present invention also relates to a product forming a cardboard tubular cylinder such as a body of fat or the like obtained by the method described above.
  • a machine for manufacturing cardboard tubular cylinders from paper in the form of a strip advantageously a paper used for packaging and known under the trade name of Kraft paper, conventionally comprises and successively a reel 1 for supplying paper, advantageously with braked unwinding, a device for reels arranged 2 for pulling said strip of paper and bringing it onto a reel 3 mandrel. Throughout its travel, the paper strip 4 is kept under tension and guided by guide rollers 5.
  • the strip 4 of paper passes through a device 6 known per se enabling the fibers of the paper to be broken.
  • the paper runs in a cutting device 7 and a device 8 for gluing one of its faces.
  • fixed or mobile devices 9 for guiding and supporting the paper strip are arranged so as to guide the paper strip 4 on the mandrel. These devices can advantageously consist of parallel rods of any length forming a support table for the paper,
  • a counter-roller 10 is provided which can be moved by any system 11 such as a jack, lever or the like to bring it into contact with the mandrel 3.
  • the latter comprises means (not shown) such as a suction or vacuum ramp for example, for applying and maintaining at least part of the first layer of paper wound on the mandrel 3.
  • the manufacturing machine of the invention comprises drive means in rotation of the mandrel 3, of the drive means of the cutting device 7, of the fitted rollers 2 and of the gluing means 8, as well as of the counters for controlling and totaling the number of turns of the mandrel, in other words all the elements necessary for the operation of such a machine.
  • the gluing means 8 are constituted in a conventional manner by an adhesive reservoir 18 disposed above two rollers 12 and 13 rotating in opposite directions so as to entrain a film of adhesive on their surface.
  • a pressure roller 14 disposed below the sizing roller 12 is actuated to press the paper strip 4 against said sizing roller 12, as shown in solid lines in FIG. 1.
  • the pressure roller 14 is brought into the low position (shown in dotted lines in FIG. 1) so the paper strip 4 is no longer in contact with the sizing roller 12 .
  • the cutting device 7 consists of a first roller 15 comprising fixed on one of these generators a tapered blade, and a second roller 16 mounted opposite said first roller 15 and comprising at its periphery a layer of rubber.
  • the roller 15 is rotated at a speed substantially equal to the speed of movement of the paper, the blade 15a coming into the layer of rubber from roller 16 to cut strip 4 of paper passing between the two rollers 15 and 16.
  • means 17 for detecting and measuring the length of the paper unrolled and scrolling through the machine from the start of each manufacturing cycle are mounted, in a preferred embodiment of the invention at the end axis of a roller 2a of the device 2 of arranged rollers, as illustrated in FIG. 2.
  • These detection and measurement means are for example a photoelectric member with slotted discs, and are connected to a control (not shown) constituted for example by an electronic system comparing the measured value of the length by the above-mentioned means 17 to a predetermined reference value, and emitting a signal when the measured value is equal to the reference value for controlling the implementation of the sizing means 8, that is to say the rotation of the sizing rollers 12,13 and the displacement of the pressing roller 14 to apply the strip 4 against the roller 12.
  • these detection means can be constituted by the LS 800 type detection unit marketed under the ELESTA brand, and the control means are constituted by the H7 4D type servoelectronic counter-counter unit marketed under the brand. OMRON.
  • This manufacturing machine operates in successive manufacturing cycles, and therefore the stages of a manufacturing cycle are simply derived.
  • the front transverse end of the paper strip 4 is brought by the arranged rollers 2 on the mandrel 3. This end is guided by the various supports 9 so as to come into contact against the surface of said mandrel substantially between the mandrel 3 and the counter-roller 10. It is understood that at the start of each cycle, the sizing means 8 are not used and therefore the pressure roller 14 is in the low position.
  • control and detection means 17 detect and memorize the length of paper which passes between the rollers d 'arranged 2 in the case where these means 17 are mounted at the end of the axis of one of the arranged rollers.
  • the front transverse end of the paper strip is brought into contact with the mandrel 3 by the fitted rollers 2, the drive of which is controlled by a timed control, advantageously with adjustable timing.
  • a timed control advantageously with adjustable timing.
  • the mandrel is then driven in rotation, advantageously at a progressive speed, so as to wind a first layer of unglued paper.
  • control means slaved to these measuring and detection means 17 emit a signal to control the implementation aforementioned gluing means 8, in other words the rotation of the gluing rollers 12,13 and the displacement of the pressing roller 14 in the high position.
  • the reference value is calculated as a function of the distance separating the detection means 17 from the gluing means and from the mandrel, so that a length of unglued paper equal to or slightly greater than the perimeter of the mandrel is wound on said mandrel to form the first layer of paper.
  • the detection and measurement means 17 is a linear measurement, of which very precise, it is possible to precisely coincide the front edge of the paper to be glued with the front transverse end of the strip of paper wound on the mandrel 3, and thus remove the tab or flap not glued inside the internal face of the barrel body manufactured.
  • a safety length which is for example of the order of approximately 3 mm.
  • the winding of the paper strip 4 previously glued on the mandrel 3 is continued to obtain the desired thickness of the cardboard cylinder.
  • This thickness is advantageously controlled by the number of turns of the mandrel totaled for example by two revolution counters.
  • the first revolution counter triggers the cutting device 7 when the number of revolutions of the mandrel reaches a given value
  • the second counter triggers the stop of the mandrel preferably with a reputed positioning, advantageously after an additional rotation of the mandrel without winding paper to finish bonding this the outer layer. Then, the mandrel is decompressed and the cardboard cylinder is removed after the counter-roller has moved.
  • the machine is then ready to start a manufacturing cycle again by driving the feed rollers 2 to bring the front transverse end of the cut paper strip onto the mandrel 3.
  • cardboard tubular cylinders no longer having a flap or tongue not bonded to the internal surface of said cylinders, or simply a tongue of peripheral length less than 3 mm, therefore having no drawbacks when these cylinders are used as a body for packaging solid or liquid products, for example.
  • control of the means for driving the mandrel 3, of the cutting device 7 can be arbitrary, as well as the location of the means 17 for detecting and measuring the length of the unrolled strip of paper 4, without this is within the scope of the invention.
