Description

The invention relates to devices for introducing a gas carrier into an aerosol package and can be used in automatic filling and capping lines for technical, food and medicinal liquid products, for example, for sealing aerosol containers with a medicinal product and liquid propellant.

A rotary type device is known in which containers are filled, valves are installed, they are rolled and gas filled.

A disadvantage of the device is the manual installation of a siphon valve in an aerosol can.

This drawback is eliminated in the device, which is the closest technical solution to the claimed invention. The device comprises a cylinder supply mechanism, a fixed platform (base) for accommodating the cylinders. A tool plate is mounted on the platform, having a valve seat and an opening where a conical collet is fixed. A sleeve is provided in the ferrule provided with a spring factor for the valve. The beaker moves reciprocally in a horizontal plane by means of a ferrule connected to the power drive of the mechanism. On the tool plate there is an orientated valve feed feeder, made in the form of a clamshell rail connected to a pneumatic cylinder. A pusher is located on top of the glass coaxially to the collet (the rod is driven by a power cylinder). Pre-oriented valves are fed into the feeder, after which the master cylinder leads the sleeve with the sleeve to the valve seat, where the valve is thrown by a pulse of compressed air into the sleeve to the retainer. The holder with the cup is then transferred under the pusher, which pushes the valve through the spring clip, and then through the collet to the cylinder. In this case, the siphon tube is oriented in the cylinder, and by the force of the pusher, the valve, moving along the cone, unclenches the collet and is mounted on the neck of the cylinder.

The disadvantage of this device is that the installation of the valve in the cylinder is carried out by three independent actuators, which complicates the design, commissioning and operation, reduces the reliability of the device.

In addition, a loss of deformable valves was found to be unproductive when the pneumatic cylinder feeds into the spring retainer of the cup and when pushing the valves through the collet into the cylinder. In the first case

In some cases, the non-fixed valve enters the moving mechanisms, and in the second case, the thin-walled valve body, especially aluminum, which is used in the medical industry, is crushed. This leads to a loss of working time for downtime, repair, commissioning and reinstallation of valves, as well as to overuse of valves.

The aim of the invention is to increase productivity and reliability.

New design features make it possible to reliably ensure guaranteed valve loading only if there are cylinders at the assembly position, while eliminating valve deformation.

This is achieved by the fact that in the device for installing valves with a tube in an aerosol can containing a feeder for supplying valves, a pusher, a platform mounted on it, a tool plate mounted on it with a cup and a holder, and a conical collet mounted under it, a groove is formed in the glass for valve passes, the feeder is mounted above the last, the cup is spring-loaded and fixed on the tool plate, copiers are mounted on the platform, and rods are mounted on the conical collet, the free ends of which are installed with possible Stu reacting with cams, wherein the pusher is mounted rotatably and axially movable under the action of reinforced underneath the mechanical cam.

Figure 1 shows the proposed device; figure 2 - section aa in fig. 1; in Fig.Z - section bB in Fig.2; figure 4 is a section bb in figure 2; in Fig.5 is a view of G in Fig.1.

A block holder including a support disk 2 and a drum 3, on the periphery of which six identical blocks are mounted (Figs. 3 and 4), is mounted on the drive shaft 1 (Fig. Of the technological rotor of the assembly). A closed cylindrical cam 4, whose profile is fixed to the axial block holder The pusher 6, movably mounted in the drum 3, is supported on the cam 4 by a roller 5. A platform 7 is mounted on each pusher b (Figs. 3 and 4), carrying copiers 8 in which the rollers are closed 9 rods of a conical collet 11 mounted under the tool plate 12. A plate 14 loaded with a spring 13 is mounted on the plate 12 axially of the collet 11 and mounted on the periphery of the support disk 2 to the block holder.

between the plate 12 and the disk 2, on which the cage 15 is fixed on the cup 15. In the cage 15, a figured groove is made: a vertical slot 16 for the siphon valve tube and a sample 17 (Figs. 1 and 4) under the feeder 18 for feeding the valves, top of the removable strap 19.

In the initial loading position (Fig. 3), the pusher 6 and the platform 7 with the copiers 8 are in the lowest position, the collet 11 is in a diluted state, the ferrule 15 flange rests on the disk 2, the spring 13 is unloaded. Oriented valves are all the way into the feeder 18 for supplying valves.

The invention is carried out as follows.

By a piece, the cylinders are transported by the transport rotor to the loading position, where they are mounted on the platform 7. By rotating the drive shaft 1, the drum and the support disk 2 are rotated. The roller 5, moving along the groove of the cam 4, moves the pusher 6 with the platform 7 upward. As the push rod lifts, the petals of the collet 11 are closed to form a cone for guiding the siphon tube and centering the valve. At the same time, the cylinder abuts the collet - the cylinder closes geometrically with the glass 14. When the pusher 6 is further lifted, the glass 14, compressing the spring 13, rises to its highest position. Then, on the passage of the holder 15, one valve is removed from the feeder 18 into the cup 14: without sifting the siphon tube, the holder 15 by the slot 16 bypasses it, and the feeder 18 by the groove 17, after which the plate 19, the passage above the feeder 18, pushes it against the stop one valve inside the cage 15. The valve falls along the guide cup 14 to the collet 11, where it is oriented along the conical surface into the cylinder. In this case, the valve is centered in the collet 11. Upon further rotation of the drive shaft 1 under the action of the cam profile 4, the pusher 6 with the platform 7 and the copiers 8 is lowered. Synchronously, under the action of the spring 13, the plate 12, the collet 11 and the holder cup 14c are moved down. In this case, the rollers 9 do not overlap on the copiers 8. Next, the flange of the holder 15 rests on the disk 2 and stops the glass 14, the plate 12, the collet 11 with the rods 10, and the copiers 8, the platform 7 with the balloon and the pusher 6 continue to move down to the extreme initial position. The expanding profile of the copiers 8 through the rollers 9 and rods 10 distributes the collet 11,

the petals of which move along the plate 12. In this case, the valve along the conical surface of the collet 11 is lowered to the neck of the container. Then, at the unloading position, the free cylinder assembly with the valve is removed from the platform 7 by the mating transport rotor of the line (not shown in the drawing). Next, the cycle repeats. In the absence of a cylinder on the platform 7 at the loading position, the upward movement of the pusher 6 is not transmitted to the cup 14, which is held stationary by the spring 13, and the copiers 8 are moved upward relative to the rollers 9 and through the rods 10 they will lower the collet stationary in the vertical direction 11. Without being lifted in the highest position, the strap 19 of the sleeve 15 is guaranteed to pass below the feeder 18 without interacting with the valve. This eliminates the removal of the valve and blocks its supply to the assembly

The proposed structural improvement and new interconnections of known mechanisms and assemblies allow, having placed the assembly blocks in the rotor, to carry out their work in the given sequence and the necessary functioning from one drive shaft, namely: lifting the cylinder to the assembly, removing the valve from the feeder of the loading mechanism, its supply and installation in a cylinder and discharge for unloading. This advantage made it possible to integrate the assembly technological rotor into an automatic line for filling and capping aerosol containers with a medicinal product
