Definitions

  • the present invention relates to an installation for the continuous filling of an envelope and, more particularly the filling of a continuous net with a fibrous material, for example wood fiber.
  • Continuous filling of an envelope presents certain production problems when it is a fibrous material such as wood fiber. It is not possible to introduce the fibers into the envelope by means of a piston or other mechanical plunger if it is desired to obtain a regular filling density of the fibers in the envelope.
  • Document US-A-4,640,082 describes an installation for the continuous filling of an envelope, with a fibrous material, by compaction of said material in a perforated portion of a duct using an extractor hood, the air being evacuated through the perforated portion of the conduit.
  • Such a method favors the evacuation of air from the side of the envelope where the air exhaust duct and the fan are located. Consequently, the accumulation of fibrous material is not uniform throughout the section of the duct and induces an irregularity in density of fibrous material in the filled envelope.
  • the present invention therefore relates to an installation for the continuous filling of an envelope which is of simple construction and of increased reliability and which ensures a substantially uniform filling density.
  • the invention provides an installation for the continuous filling of a tubular envelope with a fibrous material, comprising a tubular support on which is threaded an envelope reserve, a conduit intended to connect the interior of the tubular support to a source of fibrous material and means for transporting the fibrous material between the source and the envelope through the conduit, said transfer means comprising a stream of air, the installation comprising further means for adjusting the air flow from the inside of the envelope to the outside, a hood arranged around a free end of the support, characterized in that the air flow is created by a fan arranged upstream of the tubular support and in that, in order to control the density of the fibrous material in the envelope, the installation comprises variable openings arranged in the hood, the hood further comprising a flap which covers the width of the support and which is movable to selectively open or close one or more of the openings.
  • Another object of the invention is to provide an installation for cutting the envelope filled into units, having a substantially regular density.
  • this object is achieved by the fact that the installation further comprises at least one nozzle for spreading a binder over predetermined areas of the tubular envelope once filled, and a cutting station for the filled envelope.
  • an installation for the continuous filling of an envelope comprises a fan 12 provided with an inlet 14 and an outlet 16.
  • the inlet 14 comprises an adjustable flap 18 whose function will be described below below.
  • a flexible conduit, shown schematically at 20 connects the inlet 14 to a reserve 22 of fibrous product intended to fill the envelope.
  • the product comprises wood fiber, the fibers having a length between 0.5 and 10 mm.
  • the outlet 16 of the fan 12 is connected to a duct 24 substantially in the form of a Y and comprising two arms 26 and 28.
  • the duct 24 comprises a tilting flap 30 intended to close one or the other of the arms 26, 28. In its illustrated position, the flap 30 closes the passage 28 and leaves the passage 26 open.
  • a rotary support 32 is mounted next to the open end of each arm 26 and 28 and comprises an actuator 34 capable of selectively turning an arm 36 around an axis 38.
  • the arm 36 comprises, at each end and symmetrically a tubular support 40 and 42 intended to receive the envelope 44 on its outer surface. In its illustrated position, the support 40 is in the loading position of the envelope 44. Rollers 46, intended to facilitate the positioning of the envelope 44 on the support 40, are arranged on either side of the open end of the support 40.
  • the envelope 44 comprises a tubular net of synthetic material, for example of polyethylene, with meshes having dimensions between 1 and 10 mm.
  • the suction set 50 comprises a bottom element 52, having a U-shaped section, pivotally mounted on a duct 54, and a hood 56.
  • the hood 56 has two flanks 58 which, with the bottom element 52, substantially surround the neighboring ends of the tubular support 42 and of the duct 54. Openings 60 closed in the bottom 62 of the hood 56 allow the passage of air between the end of the tubular support 42 and an air outlet 64.
  • the hood 56 is provided with a shutter 66 which can be moved to the right or to the left while looking at the drawing in order to be able to selectively open or close the openings 60 and thus adjust the air flow evacuated by the hood 56.
  • This hood is pivotally mounted on an axis 68 and can, therefore, be tilted with the bottom element 52 from the position illustrated in FIG. 2A to the position of FIG. 2B in order to allow the rotation of the tubular support 42 around the axis 38. This tilting is ensured by a rotary actuator 70 (see Figure 1).
  • the conduit 54 has a substantially U-shaped section and comprises means of transporting the envelope which, in the example illustrated, are belts 72. Following the end of the conduit 54 opposite the assembly d 'suction 50 are arranged a nozzle 74 for spreading a binder and a cutting station 76 for the envelope which will be described in more detail below.
  • the installation finally comprises a second conduit 78 similar to the conduit 54 which is also provided with transport belts 80.
  • the transport belts 72 and 78 are started by a variable speed electric motor 82.
  • the installation 10 thus described operates as follows.
  • a mixture of air and wood fibers is sucked in through the inlet 14 and passes through the outlet 16 towards the inside of the arm 26 of the conduit 24, the flap 30 closing the arm 28 Then, the mixture passes inside the tubular support 42 and causes the deployment of the net 44.
  • This closure can possibly be done manually.
  • the fiber loaf formed by filling the net advances in the conduit 54 and is entrained by the belts 72.
  • the loaf takes a shape corresponding to the internal section of the conduit 54. This shape can advantageously be provided by a roller or an element of guide 84 disposed on the duct 54.
  • the binder is paraffin which is heated to a temperature of about 60 ° C. The paraffin is applied around the net to form a strip 4 cm wide. The paraffin does not penetrate to the center of the net, but a penetration of about 1 cm is enough for the loaves to remain intact during cutting.
  • glues preferably biodegradable glue, or an ultra-fast contact glue based on pine resin, for example, applied using a fiberization system so that the glue fixed on the one hand the net so that it does not shrink when cutting, and on the other hand the fibers at the ends so that they do not fall.
  • the bread is cut into units.
  • the bread is first clamped by cylinders 86 before being cut by a cutting disc 88.
  • the cylinders 86 and the disc sectioning 88 are arranged to follow the movement of the bread in order to ensure a cut normal to the longitudinal axis of the bread.
  • the set of nozzles 74, cylinders 86 and disc 88 returns to its initial position as represented by the arrow 90.
  • the cut loaves pass through the second conduit 78 to a packaging station (not shown) where they are put in a plastic packaging.
  • the installation 10 comprises a second filling chain which is substantially similar to that shown in FIG. 1 and can ensure the production of breads while the searches for a length of thread on the tubular support of the other chain.
  • the flap 30 is turned and closes the arm 26 thus allowing the air / fiber mixture to pass through the arm 28 and fill the net on the other filling chain.
  • the first filling chain thus becomes ready to restart when the thread of the other chain is exhausted. It remains to load a new length of thread on the tubular support 42.
  • the present installation allows the continuous filling of an envelope such as a net in a simple and reliable manner.
  • the adjustment of the air outlet through the openings 60 makes it easy to control the filling density of the fibers in the net.
  • the installation further comprises cooling air nozzles arranged between the nozzle 74 and the cutting station 76 in order to solidify the binder before cutting the loaves.
  • the installation can ensure the continuous filling of an envelope with any other fibrous or granular material.
