Definitions
- the present invention relates to the distribution viscous or fluid material. It concerns first place a device for distributing such products, type comprising a removable reservoir supplying sealing a member for distributing said material by a fluid circuit comprising means for pressurizing.
- This type of known device is advantageous (see French patent application n ° 93 13 970 in the name of the Applicant) but has a limitation: stopping the device when the product tank is empty.
- the invention aims to remove these disadvantages and prevent dead zones from forming filled with product.
- the device of the invention comprises, placed in continuity in the circuit and downstream of the means of pressurization, a means of accumulation and distribution of product or material from the tank.
- the invention also relates to the use of a device conforming to that described above for the distribution of hot-melt material.
- FIG. 1 The installation shown in FIG. 1 has a drum 1 forming a reserve of viscous product thermoplastic 2, said drum being placed on a table lifting 3.
- Barrel 1 is closed by a heating plate 4.
- the lifting table 3 acts on product 2 and the platform heating 4 by means of a hydraulic cylinder 5.
- a double-acting pump 6 actuated by a jack hydraulic 7 with double rod 8 is mounted on the plate 4.
- the heating plate 4 is connected by a pipe 9 to a means of accumulation and distribution 10 of product 2.
- Level sensors 11, 13, 12 are placed at the barrel 1 contact to determine respectively if it is full or empty and if it needs to be changed.
- the means of accumulation and distribution 10 is supplied with product 2 from barrel 1 through the pipe rigid inlet 9 fitted with a non-return valve 15.
- the means of accumulation and distribution 10 is connected to a mixer device 16 located downstream and comprising a sealed container 17 provided with a supply conduit rigid 18 of the viscous product 2, of a supply duct 19 nitrogen 20 and an outlet 21.
- the container 17 contains an agitator 22.
- a conduit 25 connects the output 21 of the device mixer 16 to a distribution member 24, consisting of example of a gun with an extrusion nozzle 26.
- the nitrogen 20 is contained in a bottle 27 associated with a booster 42, itself connected to an injection chamber 28 placed upstream of the supply duct 19.
- the means of accumulation and distribution 10 shown in Fig. 2 comprises a machined part 29 forming a jacket, crossed by a through pipe 30 placed in continuity in the supply circuit, and diameter, at the inlet and at the outlet, identical to the diameter inside the supply and outlet lines 18.
- An chamber 31, of diameter greater than that of the line 30, opens into line 30, perpendicular to it.
- This room 31 includes a plunger 32, with an axis also perpendicular to that of line 30, flush with line 30 in rest or retracted position and able to move away from said line 30 to generate an accumulation volume of product 2.
- the tightness of the chamber 31 is ensured by a cable gland 33 placed between the machined part 29 and the plunger 32.
- the jacket 29 includes a resistor heater, not shown, for maintaining product temperature 2.
- the plunger 32 is actuated by a cylinder 34.
- the accumulation and distribution means 10 comprises two sensors 35, 36 for respective re-entry and exit positions of the plunger 32.
- the cylinder 34 is actuated by a fluid F controlled by a distributor 37, yes causes the displacement of the plunger 32 when the sensor 12 is actuated replacement level from tank 1 to sensor 36 of position output from piston 32, yes acts on a means for authorization to change tank 1.
- line 30 ensures the continuity of movement of product 2 by a progressive enlargement up to the diameter dimension of chamber 31, so as to avoid the areas where the product could stagnate.
- Barrel 1 is placed and centered on the table lift 3 which keeps product 2 and the plate 4 with constant force thanks to the jack 7.
- the product 2, pressurized in line 9 by the pump 6, is directly admitted into the means of accumulation and distribution 10. Since means 10, the product then supplies the mixer device 16.
- Nitrogen 20 from bottle 27 is admitted in the hydropneumatic booster 42 which raises the pressure around 300 bar. Nitrogen under pressure is introduced into the mixing device 16 through the conduit inlet 19, after crossing the injection chamber 28. By a movement of the agitator 22 in the container 17, the product 2 and nitrogen 20 are mixed to form the material to be dispensed, which leaves the mixing device 16 through outlet 21. Under the effect of temperature and pressure, said material is conveyed by the leads 25 to the gun 24 which extrudes it to form for example a seal on any part to which it adheres.
- This sensor controls the movement, from its retracted position in chamber 31, of the plunger 32 by means of the jack 34 and the distributor 37, up to triggering of the output position 36 sensor piston 32. Chamber 31 is then filled with product 2, which filling at constant pressure, under the action of pump 6, also with a pressure drop as low as possible. Thus, the power of the gun 24 in product 2 is not disturbed.
- the chamber being full of product 2 the manipulator or the operator triggers the distribution of product 2 by reducing the volume of chamber 31 thanks to re-entry of the plunger 32. All the product contained in room 31 is distributed to the device mixer 16, because it cannot go up towards the barrel 1 because of the non-return valve 15 placed directly in upstream of the accumulation and distribution means 10 for avoid product returns 2 during operation said means.
- the valve 15 ensures the safety of the manipulator which changes the barrel 1. During this change, the distribution of product 2 continues.
