Definitions
- the present invention relates to a method and an installation manufacturing a molded gutter for receiving a rolling shutter. She is also relates to the trunk obtained in accordance with this process.
- the gutter boxes for receiving a rolling shutter are elongated chests which generally fit into a rectangular parallelepiped and which have a gutter opening onto a large face of the parallelepiped.
- This gutter is suitable for receiving a rolling shutter and its mechanism actuation.
- this trunk When in place and integrated into a construction, this trunk, which has the appearance of a "U" section profile, at the opening of its directed gutter down.
- wood fibers presents certain significant disadvantages.
- various compounds organic present in the wood in particular sugars, tannins and phenols, oppose rapid setting of the cement.
- wood fibers are subject to multiple deformations. Now, while drying, fibers tend to want to "unfold” and return to their original shape. That can result in faults on the trunk which can cause problems when assembly on site.
- a first type of mold is opened only at the top, ie on the side of the face opposite the two "legs" of the "U".
- the mold is filled with the mixture, it is closed with a plate, to which it is applied strong pressure. It is easy to understand that with this type of material, it is difficult to obtain a regular packing of the mixture in the mold, in particular at level of the "legs" of the "U”.
- drying the chest involves immobilizing the mold for twenty-four hours, so this one cannot be used for a other manufacturing.
- This mold is formed by a bottom plate fitted with a cradle shape complementary to that of the gutter of the safe to be manufactured and as many additional independent plates only with flat faces at the level of the trunk. Of this way, it is possible to apply pressure to each of said faces, so that the packing of fibers and cement is regular.
- the mold is immobilized for the entire duration drying the trunk.
- the object of the present invention is to remedy these drawbacks.
- the present invention also relates to an installation for implementation of the method as described above.
- the invention relates to a trunk obtained by the implementation of the process as described above.
- a safe molded for receiving a roller shutter molded for receiving a roller shutter.
- An example of such a chest has been shown partially in Figure 1.
- This trunk 1 has a shape generally known per se.
- Such a box is intended to be used in the position shown in the Figure 1 and be integrated into the thickness of a wall receiving a door or a window to be fitted with a rolling shutter.
- This chest is made of a mixture of wood fibers beforehand moistened with an aqueous solution of a chemical inerting agent, at least minus a cement and water.
- a plasticizer or a resin the function of which is to regulate the setting time.
- a example of such a product is that sold under the commercial reference FF18 by the SIKA company.
- Wood fibers are preferably made by cutting the tree in the form of logs which are debarked and cut before being introduced into a shredder. We can then recover fibers in size ranges varied. However, fibers 50 cm long, 3 mm wide and 0.30 mm thick are suitable.
- chemical inerting agent means an agent chemical which is able to inhibit the action of naturally occurring substances in wood, such as sugars, tannins and phenols, which usually oppose the setting of the cement on these fibers.
- this agent is consisting of calcium hydroxide.
- a methodology for moistening the constituent fibers of the safe consists in soaking them in a tank where said chemical agent is in aqueous solution. A concentration by weight of the order of 2% of this agent is sufficient for it to fulfills its inerting function. Soaking the fibers in the solution for a few minutes are enough to saturate them with water and for the inerting agent produce its effects.
- the fibers are preferably drained before being mixed with the cement (s).
- Figure 2 is shown a block diagram of an installation according to the invention, with its various positions.
- Station 2 is a station in which wooden logs are worked so as to form fibers of uniform length.
- a conveyor belt taken up, for example by a conveyor belt, to be poured into a hydration tank 3 comprising a mixture of water and chemical inerting agent.
- a conveyor partially bathes in this bin and collects the fibers saturated with water and soaked with inerting agent and directs them to a mixing 4 which is connected to a cement supply station 5. From preferably, the latter is suitable for introducing into the mixer the quantity exactly necessary for making the mixture.
- the conveyor can be equipped with automatic weighing means, so that, by time units determined, means such as a microprocessor calculate the amount of cements to be incorporated into fibers.
- the fiber / cement mixture is then transferred from station 4 to station 6 weighing, via a conveyor belt 40.
- This conveyor of conventional type, is adapted to receive the mixture fiber / cement and transport it to a hopper 61.
- This conveyor is not only articulated around a horizontal axis, which allows it to vary its inclination, but also around an axis vertical 41.
- hoppers 61 and 62 which are integral with a chassis 600 and which receive the mixture fibers / cement.
- hoppers which take the form of a longitudinal cradle and which are formed of two parts articulated around longitudinal axes 63, at the like the jaws of an excavator. In this way, the mixture received in the hoppers can be evacuated by gravity, by the opening of the two parts which constitute the hoppers.
- the two hoppers 61 and 62 are normally superimposed, so that the mixture received in the upper hopper 61 can be poured into the hopper lower 62, following its opening.
- the latter is only ordered when weighing system (not shown) which equips the chassis 600, detects that a weight sufficient fiber and cement has been introduced into the hopper 61 to achieve a chest.
- chests having different dimensions, for example 300 min in height and 300 mm in width.
- the fiber / cement mixture can then be brought to a new item 7 designated "transfer station”.
- this post is materialized by a mobile and motorized shuttle 700 whose chassis 70, provided with wheels 71, is equipped with means for receiving the content of the hopper 62.
- These means consist of a receptacle 72 consisting of a moving belt conveyor 73, provided with side rails 74 and ends removable 75.
- Suitable means and not shown allow not only to cause the movement of the strands of the conveyor 73, but to move it longitudinally relative to the frame 70 of the shuttle 700 (see arrow g , Figure 8).
- the latter is also equipped with support means 76 for a mold base element 80 on which is fixed a core 81, whose shape is complementary to that of the gutter of the mold.
- the support means 76 advantageously consist of a series contiguous rollers, freely rotatable around their own axis.
- the shuttle 700 ensures the transition of the fiber / cement mixture from weighing station to a station 8 for molding and pressing.
- This station is formed by a chassis on which are provided means for molding of the mixture conveyed by the shuttle 700.
- These means consist primarily of the bottom element 80 and its associated nucleus 81.
- the other means consist of as many mold elements that there are faces on the trunk to be manufactured.
- Each of these elements is associated with at least one jack V , the function of which will be explained below.
- the longitudinal elements 83 and one of the end elements 84 are controlled by the cylinders V so as to be made contiguous.
- each of the faces of the mold is pressurized by through the cylinders associated with them.
- the mold elements are preferably made of steel.
- a transfer station 7 consisting of shuttles of the same general type as the shuttles 700 already described, are then able to recover the trunk 1 and its associated bottom element, to transport it to a drying station 9.
- the storage period is for example of the order of twenty-four at forty-eight hours. At the end of this period, we separate the trunk from its support, which can be produced for a new manufacture.
- the trunk can be cut off on request to present the desired length.
- Figures 11 and 12 show a simpler installation implementing the method according to the invention.
- This installation comprises means D for storing fibers and cements and for pouring D 1 of these onto a movable conveyor belt 40 ′.
- the means D are able to be moved along the conveyor 40 ′, as shown by the double arrow in FIG. 12, so as to distribute the mixture well over its entire surface.
- This conveyor incorporates a weighing station P of the mixture which it carries.
- the downstream end of this second conveyor is located inside a humidification station for fibers and cement.
- the sprayed liquid is consisting of an aqueous solution of chemical inerting agent.
- the products are discharged, inside station A, from the conveyor 60 ' to a third conveyor 61 ', the upstream end of which is perpendicular to the end downstream of the conveyor 60 '.
- the installation includes a fourth and last conveyor 62 ' of the trough type, arranged perpendicular to the third, in which the humidified mixture.
- the method and the installation in accordance with the invention make it possible to manufacture safes at lower cost. Indeed, if it is necessary to have as much bottom elements only boxes to be manufactured, the other elements are immobilized only during the pressing stage of limited duration. So they can be quickly reused.
