Definitions
- the present invention relates to the extrusion of all pasty products such as sealants, glues, greases, etc. stored in standard cartridges.
- mechanical or compressed air guns are generally used intended to act on the movable bottom of the cartridge in order to move it axially.
- Air pistols produced by a compressor are also used. This type of gun wastes a large amount of air due to its operation. Indeed in order to neutralize the pressure exerted behind the movable bottom of the cartridge and in order to stop the output of the product clean it is necessary each time that the trigger is released to drain the air at the rear of the movable bottom of the cartridge. This requires the compulsory use of a compressor which delivers thousands of liters of compressed air without counting.
- the outlet of the cartridge is associated with a flexible tube on the end of which is mounted the injector intended for the pouring of the pasty product.
- the tube is mechanically deformed in order to stop the spillage of the material.
- the rigid end piece with which the outlet of the cartridge cooperates is provided with a simple ball valve which opens or closes this end piece so that the material may or may not be ejected.
- a simple ball valve which opens or closes this end piece so that the material may or may not be ejected.
- Such a tap does not require the purge of the volume located below the movable bottom of the cartridge, but its manipulation of the tap entails on the one hand the obligation for the user to use both hands and can on the other hand be countered in case of polymerization of the substance in the tap; in this case it can get stuck in the open or closed position.
- the improvements which are the subject of the present invention aim to remedy these drawbacks and to ensure the production of a putty gun using only a very small amount of gas, which makes it possible to eliminate the compressor which is replaced. by a small industrial nitrogen bottle.
- the pistol according to the invention allows, by operating a simple trigger, to close or to open a flexible tip following the opening of the cartridge, this action being carried out pneumatically.
- the piston of a single-acting cylinder is associated with the flexible end piece which follows the opening of the cartridge to crush it when said cylinder is supplied by a flow of compressed gas derived from the one which acts. on the movable bottom of the cartridge, said flow being sent into the jack considered as soon as the user releases a trigger, while the actuation of the latter causes said flow to stop and release the endpiece for allow the expulsion of the pasty product.
- a device Illustrated in fig. 1 a device according to the invention comprising an armature 24 associated with a handle 15, said armature carrying on its front part a block 1 while its rear part receives an open jack 28.
- the block 1 which is fixed to the front of the frame 24 by means of two screws 34, 35 (fig. 2) comprises a longitudinal bore la in which is engaged a flexible tube 2 comprising a tubular head 2a of larger diameter which is supported on the internal face of the block 1 by means of a collar 2b.
- the head 2a engages in a counterbore Ib of the block 1.
- the end of the tube 2 opposite its head 2a projects out of the block 1 and can receive a threaded ring 2c intended for example to receive a discharge nozzle not shown.
- Another bore lc is formed in the block 1 perpendicular to that la.
- This bore opens on the base of the block 1 while its part with a smaller diameter ends in the bore la.
- the bore lc receives a piston 4, the head of which cooperates with the large-diameter part of the bore lc, its tail engaging in the part with smaller diameter of said bore.
- a return spring 3 is provided so that in the free state the tail of the piston 4 is not in contact with the periphery of the flexible tube 2 (fig. 3).
- the neck of a cartridge C engages inside the tubular head 2a of the flexible tube 2, the seal between the cartridge and this tube being made by bearing the shoulder of the cartridge against the flange 2b.
- the rear part of the frame 24 supports an open jack, the cylinder 28 of which is secured to this part of the frame by a heel 14 and a transverse screw 31.
- the cylinder 28 is open in the direction of the block 1 and we have committed to inside the bore of this cylinder a piston 30 produced for example by means of an elastomer.
- the piston 30 comprises a peripheral lip 30a which cooperates in leaktight manner with the bore of the cylinder 28.
- This piston 30 constitutes a stop for a spring 29 which tends to push the said piston outwards from the cylinder 28.
- the race towards the exterior of this piston is limited by a screw 27, the head 27a of which bears in leaktight manner against a shoulder 30b of the center of the piston 30.
- a sealing washer R can moreover be associated for this purpose with the face of the 'shoulder 30b opposite the head 27a. Note the presence of two longitudinal holes 30c, 30d communicating the interior of the cylinder 28 and the exterior so that if the compressed gas arrives in the cylinder 28 when no cartridge is in place, a leak occurs which prevents the reversal of the lip 30a.
- the compressed air arrives in the cylinder 28 through a perforation 24c of the armature 24 connected to the interior of the cylinder consi drained by a slide valve 22 illustrated in fig. 7.
- the frame 24 is provided with a transverse groove 24d, the bottom of which has a bore 24e ending in the perforation 24c (FIGS. 6 and 8).
- a flat drawer 34 comprising two extreme stops 34a, 34b which limit its axial movement, the distance between these two stops being greater than the length of the groove 24d.
- the hole 24e of the frame 24 is in correspondence with an opening 34c of the drawer which itself comes opposite a hole 28a formed in the cylinder 28 (fig.
- the top of the drawer 34 having a longitudinal groove 34d.
- one of the ends of the groove 34d is brought opposite the hole 28a so that the inside of the cylinder 28 is placed in communication with the outside (fig. . 9).
- seals 35, 36 are placed on either side of the drawer 34 respectively around the outlet of the holes 24e and 28a.
- the perforations 24a and 24c are supplied with compressed air from the valve 8 by means of pipes 25, respectively 21 (fig. 1).
- the valve 8 which is fixed below the frame 24 by means of a screw 7 comprises three channels 8a, 8b, 8c (fig. 10) in which the pipes 25 and 21 are fitted respectively, as well as a tube 19 the free end of which constitutes a nozzle to which the compressed gas supply is connected. It is observed that the channel 8c opens into that 8b so that the pipe 21 is supplied directly with gas.
- a blind stepped bore 8d is formed longitudinally in the valve 8. It is noted that the part with the smallest diameter of the bore 8d is in communication with the channel 8c, while the channel 8a opens into the part with the largest diameter of the said bore .
- valve 10 made in the form of a needle having a flange 10a.
- This valve leaves the valve 8 through a cable gland 33 so that its free end comes cooperate with a trigger 13.
- a spring 18 pushes the valve outwards as illustrated in FIG. 1, 10. and 11.
- the flange 10a of the valve 10 is placed along the length thereof so that in the extended position, that is to say when the trigger is not actuated, the outlet of the channel 8a is located at the rear of this flange so that the gas entering the valve 8 through the tube 19 can flow into the channel 8a and the pipe 25 through the rear part of the bore 8d.
- an O-ring 11 is disposed between the flange and the gland 33 so that there is no leakage along the valve when it passes through said gland and that it is in advanced position.
- an O-ring 12 is associated with the shoulder formed by the two diameters of the bore 8d as will be explained below.
- the gas arrives in said cylinder, passes through the annular space between the screw 27 and the central hole of the piston 30 as well as the holes 30c and 30d to come under the movable bottom of the cartridge in order to exert pressure on it .
- the gas arriving through the pipe 25 actuates the piston 4, the end of which clamps the tube 2 so that the pasty product cannot exit the tube.
- the piston 4 is returned downwards by the spring 3 so that the tube is released and the product leaves the tube due to the air pressure on the movable bottom of cartridge C.
- the gas which has just acted on the piston is expelled towards the outside by passing through the annular space between the cable gland 33 and the valve 10.
- a device has thus been produced which allows a substantial saving of compressed air, so that it can be supplied by means of a gas cylinder, in particular when the supply of compressed air is difficult, for example when the user is on the roof of a tall building.
