(54) AUTOMATIC MACHINE FOR DRAWING A REFLECTIVE LAYER ON THE INTERNAL SURFACE.COLUB PIPES AND DRYES OF THIS LAYER

This invention relates to electro. technical use, to equipment for the production of vacuum devices, in particular, to all tomatoes for the application and drying of the reflective layer on the inner surface of the tubes of luminescent lamps.

A device for applying a diffuse-reflective coating on the inner surface of flasks of luminescent lamps is known, in which the principle of pouring slurry into horizontal flasks-tubes is applied to a certain level corresponding to the angle of application of the Reflection layer, followed by draining the slurry and drying it. go layer 1.

The disadvantages of this device are the poor quality of the deposition of the reflective layer, since it is suspended during pouring. ZIN and when draining along the entire length of the flask, wavy lines form; the inability to replace manual labor and process automation; low productivity and greater complexity in the management process .30

The most important to the invention by its technical essence is the well-known automatic machine for applying a reflective layer on the tube-tube and drying it, which contains a chain conveyor mounted on a frame with two parallel branches, a driving sprocket with a drive and driven sprockets, a hopper for loading flasks -pipes, slurry dispenser, heater for drying the reflective layer, slips for receiving finished flasks, clamping devices for flasks-tubes with caps, rollers and funnels for pouring slurry, fists to act clamping devices, a drum for receiving and clamping flasks, grips, tilting devices and a bath for draining excess suspension 2.

However, the known machine is complicated, since it is necessary to drain the excess suspension, which also reduces the performance of the machine.

The aim of the invention is to improve the performance of the machine.

The goal is achieved by the fact that in the automatic machine for applying a reflective layer on the inner surface of the flasks. Tubes and drying this layer, contain a hopper installed on the frame for loading the flasks-tubes, a dispenser. suspension, heater for drying the applied layer, slippery for receiving finished flasks-tubes connected with water: a drum with discs for receiving flasks-tubes and clamping devices installed on it with a uniform pitch with caps, rollers and funnels for pouring slurry, fists For acting on the clamping devices, the clamping devices are additionally equipped with gear wheels in constant engagement with two gear wheels mounted on the shaft of the bar on both sides connected by gear wheels. transmission and electromagnetic clutch with drum drive. The technology of this automat is based on the suspension in the flask-tube in such quantity as is required to obtain the reflective layer, turning the flask-tubes clockwise and against it in order to voluntarily pour the suspension into flasks, which is ensured by the presence of gear wheels on the clamping devices flasks interacting with two driving wheels mounted on the drum shaft. FIG. 1 schematically shows an automaton, side view; in fig. 2 view A in FIG. one; in fig. 3 - kinematic scheme of the automaton. An automaton consists of a drum 1 (Fig. 1) located horizontally but also rotating at a constant speed. The drum 1 is fitted with clamping devices 2 rotating with the drum 1. For acting on the clamping devices, there are fixedly mounted fists 3 on the bed 4. On the bed 4 there is a hopper 5 for loading the flask-pipe b to the drum 1 individually with the help of a cutter 7, performing forward movement up and down, dispenser 8 for supplying a portion of the suspension to the inside of the flask tube 6, heater 9 for drying the applied reflective layer, skli 10 for receiving ready flasks tubes, heel 11 in which the shaft 12 rotates, on which the wheels 13 are rigidly fixed to rotate the flasks-tubes. The clamping device 2 consists of a lid 14 (FIG. 2) for tightly sealing the ends of the tube-tube b, which is rigidly visible on the roller 15. On the roller 15 there is a rigidly mounted gear wheel 16, which serves to rotate the flasks of tube 6 together with the roller 15 and the cover 14 in the bearing 17. The bearing 1 fixes the position of the roller 15 and the wheel 16 and the cover 14 rigidly mounted on it. The bearing 17 reciprocates by means of the action of the cam 3 on the roller 18, which is rigidly connected to the sub- bearing. 17, a guide 19, freely sliding in the sleeve 20, inside which There is a spring (not shown in the drawing) serving to return the bearing 17 to its original position. To move the bearing 17, a guide 21 is mounted only in the horizontal direction, which moves in a sleeve 22 rigidly mounted on the drum 1. The drum 1 rotates in bearings 23 that are fixedly mounted on the frame 4 .. The drum 1 receives rotation from gear 24, which is rigid mounted on it and receives rotation from gear 25. Wheels 13 rigidly mounted on shaft 12 receive rotation from gear 26 fixed on shaft 12 and engaging gear 27. In the roller 15 and in cover 14 a hole is drilled for the bay suspension through a funnel 28, rigidly mounted on the roller 15. The gear 27 sits firmly on the shaft 29, which receives a periodic rotation through the clutch 30 to disable the rotation from the shaft 31 (Fig, 3). The shaft 31 receives a constant rotation through the V-belt transmission 32, through the gearbox .33 from the electric motor 34. The machine works as follows. The electric motor 34 is switched on, which, through the gear 33, the V-belt transmission 32 ,. shaft 3.1, gear 25 and gear 24 drives the rotation of the drum 1. In this case, the clutch 30 is disconnected and. the shaft 29 is not driven into rotation, therefore, the wheel 13 also does not rotate. When counterclockwise rotation of the drum 1 in the place of loading of the flask tubes with the help of the shutter 7, the tube-tube b is fed from the hopper 5 into the groove of the drum 1. At this fist 3, the bearings 17 are retracted on both sides of the automaton bearings 17c by rollers 15, the gears 16 and the lids 14 to the extreme, the position and the cone tube 6 do not touch the lids. The bearing 17 moves due to the movement of the guides 19 and the guides 31 in the sleeves 20 and 22. With further rotation of the drum 1 due to the knuckle 3 and the impact of the springs (not shown) in the sleeves 20 and 22, the bearings 17 move in the bulb -tube 6 and lid 14 tightly, but close the ends of the flask-tube 6. After closing the ends of the flask-tube enters the zone of pouring the suspension into the inner part of the flask-tube. Pouring a portion of the suspension, in the quantity required directly for applying the reflective layer, is carried out by metering 8 through the funnels 28 and the hole (not shown) in the roller 15 and in the roof: 14, connecting the funnel 28 seconds the inside of the bulb-tube 6. When the drum 1 moves counterclockwise, the wheels 16 on both sides of the machine move with the drum 1 and, rolling on the wheels 13, turn clockwise and at the same time also turn the flask tube b around its axis, which is tightly held shkami 14 ,. The suspension, located in the interior of the tube-tube, spreads in a uniform layer along the inner wall of the tube-tube. At constant rotation of the drum. 1, at certain intervals, the clutch 30 is turned on and the shaft 29 begins to rotate with the gear 27. The gear 27 transmits the rotation of the gear 26, which through the shaft 12 rotates the wheels 13 too counterclockwise like the drum 1, with a speed greater what rotates the drum 1, while the wheels 16 will rotate counterclockwise at a certain angle equal to the angle of application of the reflective layer, after which the coupling 30 is turned off and the shaft 29, gears 27, 26 and the wheels 13 stop and / therefore the wheels 1 6 will begin to roll around the wheels 13, rotate clockwise and rotate the flask tube around its axis at a certain angle equal to the angle of the reflective layer, after which the coupling 30 is turned on again and the flask tube 6 turns again in the opposite direction. The tube-tube rotates around its axis, first in one direction, and then in another, during the operation of the machine, is carried out at certain intervals with no power to turn the coupling 30 on and off. heater 9. After passing through the drying zone, bulb-tube 6 enters the discharge zone, where from cam 3 through rollers 18 prompting 19, bearings 17 pull caps 14 to their original position and release tube ends 6 and bulb-tube by Your own weight skatyvaets on slide-ways 10 for receiving the ready-flasks and tubes in this process on the machine ends.
