Definitions
- the invention relates to the production of an eraser for the manufacture of a tire.
- the properties of the gum during vulcanization are very sensitive to the proportions of the ingredients forming the mixture.
- the vulcanization may be either too fast or insufficient, which in both cases compromises the qualities of the rubber and those of the final tire. .
- An object of the invention is to promote respect for the proportions of the ingredients of the mixture forming the gum.
- a grille forms a tablecloth with a mixture of ingredients from the eraser while a conveyor moves the web in a first direction
- the conveyor moves the web in a second direction so that the mass is between two faces of the web extending one against the other.
- the web is circulated in the form of a closed loop.
- a device comprising the calender and the conveyor opens the loop to form two free ends of the web.
- the product forming the mass comprises a compound promoting the vulcanization of the gum.
- the method of the invention is not restricted to this case because it also allows to add to the mixture of other complementary products that a vulcanizing product, but it is well suited to such a product for which the respect proportions are of great importance.
- the deposition of the product is carried out only after a temperature of the web has become below a predetermined threshold.
- the conveyor carries out the evacuation in the second direction.
- an installation for producing a rubber capable of implementing a method according to the invention, and comprising a calender, a first conveyor and a second conveyor capable of dropping the mass directly. on a portion of the web supported by the first conveyor.
- the second conveyor has an end located above the first and facing the latter.
- the second conveyor does not extend vertically from the calender and is therefore neither above nor below it.
- the installation comprises internal refrigeration means to the calender.
- the second conveyor extends upstream of the calender with reference to a direction of evacuation out of the installation by the first conveyor.
- the installation comprises a third conveyor inclined relative to the vertical direction and having an end located above the calender.
- This conveyor makes it possible to circulate the sheet in a closed loop.
- the installation comprises refrigeration means internal to the third conveyor.
- the second conveyor has an end located below the third conveyor.
- Figures 1 and 2 are respective views in plan and elevation of a mixing station of an embodiment of an eraser according to the invention.
- Figures 3, 4 and 5 illustrate successive steps of the present embodiment of the method of the invention by means of the installation of Figures 1 and 2.
- FIGS. 1 and 2 show a station 2 of an installation for producing a rubber for a tire according to the invention. It may be a light vehicle wheel tire, a passenger vehicle, a commercial vehicle, a heavy vehicle type vehicle or a civil engineering machine wheel.
- the station 2 comprises a horizontal lower belt 4 in the form of an endless band able to circulate while being held and driven between two rollers 6 whose axes defining the axes of rotation are horizontal and rotatably mounted relative to a post 8 building.
- the two walls of the carpet are horizontal.
- the station comprises a vertical belt 8 arranged in the form of an endless belt able to circulate while being held and driven between one of the rollers 6 and a roller 10 extending over this last.
- the two walls of the carpet 8 are vertical.
- the station 2 also comprises a lift belt 12 in the form of an endless loop able to circulate while being supported and driven by an upper roller 14 and a lower roller 16 of larger diameter than the roller 14.
- the roller 14 extends away from the roller 16 in the horizontal direction and in the vertical direction.
- the belt 12 comprises internal refrigeration means 33 located between the two layers of the strip or in at least one of the rollers 6, 10.
- the station 2 further comprises a shell 18 having two cylinders 20 identical to each other and arranged opposite one another with their geometric axes of rotation 22 parallel to each other.
- the two rollers extend apart from one another and above the horizontal carpet.
- the calender includes means 34 refrigeration internal rollers.
- All axes of the aforementioned rollers 6, 10, 14, 16 and the axes 22 of the cylinders are horizontal and parallel to each other.
- the station 2 also comprises a horizontal introduction belt 24 having a closed loop-shaped strip able to circulate while being held and driven by two rollers 26 having horizontal axes 28 parallel to each other and perpendicular to the aforementioned axes.
- the horizontal upper wall of the belt 24 moves in a direction perpendicular to the direction 29 of movement of the wall of the lower belt 4.
- the belt 24 is able to circulate so that products disposed on its upper face are discharged by the end 27 located in the upper part of Figure 1. This end extends above the lower belt 4, facing the latter, about midway from its ends formed by the rollers 6.
- the station comprises a transfer belt 30 having a strip arranged in the form of a closed loop able to circulate while being held and driven by rollers 32, only one of which is visible in FIG. an axis parallel to that of the roll 6 and extends below the latter.
- the roller 14 extends over one of the cylinders 20 without covering the other cylinder 20.
- the elevator belt 12 extends over a portion of the introducer belt 24 and particularly of its unloading end.
- the roll 16 extends opposite the two belts 4 and 8 and the cylinder 6 which supports them both.
- the introducer belt 24 is next to the grille 18 without being vertical to the latter.
- the mass of rubber 35 passes through the calender 18 between the cylinders 20 rotating in opposite directions and forms a sheet.
- the lower belt 4 is moving so that its upper wall moves to the left as shown in Figure 3.
- the vertical belt 8 is moving so that its right wall moves upwards.
- the rollers 14 and 16 are rotated clockwise so that the upper wall of the belt 12 rises during the movement of this belt.
- the rubber forms a web which is deposited on the upper wall of the lower belt 4 and is transferred towards the vertical belt.
- a closed-loop web is thus formed which circulates continuously in the clockwise direction as indicated in FIG. 3, from the calender to the lower belt and then on the elevator belt and again in the calender, and this several times.
- the rubber accumulates in the calender upstream of the rollers to reform a sheet at the exit thereof.
- This circulation therefore leads to further mixing and mixing of the ingredients.
- the refrigeration means 34 lower the temperature of the gum which also undergoes a lowering of its temperature due to its contact with the air and the other organs of the station 2. While its temperature reached 170 ° C before arriving at the station, at the end of this traffic, it reaches about 80 ° C. These values are given only as an example.
- the circulation of the web takes place for example between one and four minutes, preferably for two minutes.
- a block of vulcanizing product 36 is introduced into the station a block of vulcanizing product 36.
- This block has in this case a rectangular parallelepiped shape. It forms a mass of product proportionate to the constituents of the mixture forming the gum.
- the block 36 is introduced by the belt 24 which conveys it through its upper wall to the unloading end 27 and drops it directly on a portion 37 of the sheet supported by the lower belt 4 and therefore being in the lower half of the latter.
- the block is thus disposed on an upper face 38 of a portion 37 of the web whose kneading station 2 is now completed since this portion will not iron in the calender.
- a portion of the latter is still supported on the entire upper face of the elevator belt 12 and another by the calender 20 in which it completes passing.
- the assembly is then sent to a finishing station where the web and the vulcanizing block are mixed.
- the gum 35 and the vulcanizing block 36 of the station 2 are transported to the next station of the installation in a configuration such that the block is wrapped in the sheet. This prevents the loss of vulcanizing material material during the transfer of this set.
- control means 42 able to control all or part of the steps of the method just described.
- These means advantageously comprise one or more microprocessor and memory computers and a program comprising code instructions able to control the execution of these steps when these instructions are executed on a computer.
