Description

The existing sleeve-hole machines are designed on the principle of reciprocating movements and have heavy adjustments, due to which it is difficult to eliminate the gap of sleeves (defects) and parts are quickly worn out, which means a large number of downtime and an increase in depreciation costs associated with repairing the machine. . In order to eliminate these drawbacks and increase the productivity of the machine with an increase in revolutions up to about 460 rpm, in the proposed machine, two grooved drums (mitralles) are used, transmitting sleeve shirts to the mouthpieces, and then to the rolling pins. Rolling studs located in the drums get a movement along with them, then around their own axes using gears and, finally, forward movement from the pushers and back using gripping tongs.

In FIG. 1 shows a side view (in partial section) of the sleeve machine; FIG. 2 is a view from above; FIG. 3 front view; FIG. 4- view of mitralia from the sleeve shears.

75)

The liner paper, sewn with brooch 1 (Fig. 2) into the liner shirt (paper tube), passes through the guide tube 2 and then through the liner shears 3 enters the chute (receiver) 4 between mitralies 5, 6. Cut with scissors and the sleeve of a certain shirt the length of the distributor foot 7 periodically pushes from the receiver 4 into the corresponding well (channel) of mitraliases 5. The foot 7 receives a swinging movement from the eccentric 8 and the lever with roller 9 at the end. The second last sleeve shirt from receiver 4 with foot 7 pushes already into the hole of the second mitraleza 6, the cope, turning in the direction indicated by the arrow (Fig. 3), together with the sleeve shirt located in the hole, goes under the cover 10. Periodic the rotation of mitrales 5 and B. is arranged according to the fixation system (Fig. 1), i.e., by means of a screw 11 and a correction tooth 12, which are one whole, fixed on the shaft 13 and in engagement with gear 14, which sits on roller 15 mitrales 5, 6. When the shaft 13 rotates, the gear 14 then rotates when the shaft lenii to the worm 11, is stopped at the exit of the screw of the engagement and approach

into the cuts of the gear of the correctional tooth 12, which closes the gear 14. Thus, the paw 7 is the distributor of the stitched sleeve shirts to mitralesa 5, 6, and the latter are the mechanism that feeds them to the month where the mouthpiece is inserted into the gil: .

Against the mitralia holes, there are legs 24, which press the stitched sheath shirt against the wall of the mitrales hole. The pen, which is located at the end of the slider 23, pushes the rolled mouthpiece into the sleeve shirt, and as soon as the feather enters the shirt, at the same time, the foot 24 moves back (Fig. 3). The movement of the tab 24 takes place with the help of a lever and an eccentric at the time when the sleeves with the mitralles movement are inserted upwards (fig. 1).

The drums 29 are located in the Holy Mitralese, in which the rolls are mounted, and the studs 27 receive movement along with the drums 29 and around their own axes. The continuous movement of the studs around their axes is carried out by means of gears 99, which are located in engagement with the rings 100, mounted on the drums and having gears 101 both outside and inside. The ring gear 101 engages with the gear 102, which sits on the roller 103. On the same face, the drum 31 is fed into the box. The roller 103 receives movement from the shaft 13 through a series of cylindrical gears 104, 105, 106 and bevel gears 17 (Fig. 2). The rotation of the drums 29 comes from the roller 15 (Fig. 1) mitrales 5, 6, on the left end of which is cylindrical gear 96, which through rotation 97 rotates the roller 98 with the drum 29. fixed on it. Mitrales 5, 6 rotate alternately occupy a position when the ends of the sleeves in the holes are installed against the rolling studs 27. With the help of the pusher 28, the pin enters the sleeve with a grooved end, and as the drum moves further, the sleeve 29 is put on the hairpin, lifted from the mitralese hole and fits under the sleeves A second roller 30, creating an abutment for the rolling pin, which, all the while rotating, produces an internal rolling of the liner. After rolling, the sleeve falls under the corrugated feed drum 31 and is slid 32 (Fig. 3) into the sleeve box 33, from where the finished sleeves are removed by a worker.

Before the sleeve enters the drum 31, the grooved end of the pin is pulled out of the sleeve by means of tongs 34, and the sleeve is maintained at this time (otherwise the sleeve would tilt) in a certain position with a fork 35. fixed on a roller 36, at the other end of which a lever 37 with a roller 38 receiving movement from an eccentric 39 mounted on a roller 103 (FIG. 2). At the moment of rolling out the rolling pin from the sleeve, the fork 35 is lowered into transverse ditches: both the drum 31 and the sleeve freely passes along the hill 32 under the corrugated drum 31 into the sleeve box 33. The movement of the pusher 28 of the rolling studs 27 and the tongs 34 is produced by applying 1 chuck 23, on which the rack 107 is fastened, connected to the lever 108 carrying the pusher 28 and the tongs 34 (FIG. 2). Thus, when the slider 23 moves to the left or right, the movement of the pushers 28 and the ticks 34 also occurs.

To rest the sleeves during insertion, the mouthpiece serves as a stop bar 111, adjustable by means of a screw 112. The mouthpiece remover 25 is fixed on the lever 26 (Fig. 2), which is rocked by the roller 109 at the end of the lever and the eccentric 110 sitting on the roller 18.

At the right end of the roller 18 chords 16 are reinforced, unwinding the tipping paper. The roller rotates by means of bevel gears 17 from the shaft 13.

When the pen has completely put the sleeves on the shirt in the mitralese hole, removing the fir-tree 25 with its movement sticks out the mouthpiece from the pen and holds the sleeve shirt until the pen completely comes out of it. Simultaneously with the movement

the holes of the mitraleza, i.e., turning it, the lever of the renter 25 moves back from the mitraleza Thus, it is intended to make adjustments (up to 0.1 mm) of the position of the sleeves located between the two stops of the pick-up 25 and the anvil 111 in the course of the machine.

The main shaft 40 of the machine carries a flywheel 41 and two eccentrics 42, 43, driving the THIS. Shells 3 into motion by means of a lever 44, a slider 45, a spring 46 and a second lever 47.

The rotation of the shaft 40 by means of cylindrical gears (no drawing is shown in the drawing) is transmitted to the second shaft 48 (Fig. 2), at the other end of which the cylindrical gear 49 and the bevel gear 50, shown by a dotted line in FIG. one.

The cylindrical gears 49, 51 through the crank mechanism 52 and the connecting rod 53 rotate the lever 54, the upper end connected by means of a pull 55 (Fig. 2) with a prismatic slide 56 (Fig. 1); in the clamping rack 57 reinforced slider 23 with a feather on the end.

Through bevel gears 50, 58 (Fig. 1), the movement from the shaft 48 is transmitted to the third shaft 59. At the right end of the shaft 59 there is a cylindrical gear 60, which is connected to the gear through the gears 61, 62, 63.64 (Fig. 2) 65 clockwork. The latter is a loosely-mounted sleeve 66 with an annular groove 67,: shown as a dotted line in FIG. 2, and the prong 68, which collectively constitute one piece, having free movement to the right or to the left and at the same time rotating. At that moment, when rotation of the twist wedge 22 is required for twisting the mouthpiece, the sleeve 66 is moved to the left by means of the rocker arm 69 and the fork through the annular groove 67.

The swing of the rocker arm 69 is performed by the lever 70 (Fig. 2) through the roller 71 and the eccentric 72, mounted on the vertical roller 73 (Fig. 1).

The roller 73 is driven into rotation by the bevel gears 74 and 75 from the shaft 59 P: 1 and the swing of the rocker arm 69 (Fig. 2), the tooth 68 of the sleeve 66 engages with the same tooth 76 of the twist sleeve 77, which is fixed on the spindle shank 22.

When the teeth 68 and 76 are uncoupled, to precisely stop the rotation of the shpindles 22, the contactor 78 serves as a tooth that enters the double cut of the coupling 77. The closing moments are associated with the moments of contact of the rocker arm 69 and stop 79, reinforced on the rocker arm itself. In addition to the movements already disassembled, from the shaft 59 there is also a transmission of movement to the auxiliary roller 82 by means of the cylindrical gears VO and 81.

In turn, the rotation of the roller 82 through the helical gears 83 and 84 (Fig. 1) is transmitted to the roller 85, rotating the bearing in the bearing 86 and carrying two eccentrics on each side.

One of them 87 serves to drive the blades of shears 20 through the roller 88, the lever 89 and the roller 90 located in the bearing 91; the second eccentric 92 through the roller leads in the swinging movement of the chipper mouthpiece 21.

The movement of mitralia is carried out as follows. At the left end of the auxiliary roller 82, viptov shchestrin 93 is strengthened, by means of which the screw 13 is transmitted through the screw shanks 94 and 95 to the shaft 13, and with it the screw 11 with the corrective tooth 12, which alternately meshes with the gear 14, then rotates it together with the roller 15 and mitraleza 5 or 6, then make a dead stop when the correction tooth 12 enters the gear 14.

The subject matter of the invention.

The sleeve machine is characterized by using two grooved drums (mitrales) a and 6, transmitting the sleeve shirts, fed to them by a distributor foot 7, first to the mouthpieces, and then to the rolling pins 27,

equipping the drums 29 and following three movements: 1) together with the drums 29, 2) around their own axes by means of gears 99 coupled to the rings 100 put on

drums and fitted with toothed rims, both outside and inside, and 3) forward-forward from the pushers 28 and back with the help of gripping tongs 34.
