SU35750A1 - Device for turning flat cigarettes seam down - Google Patents

Description

The invention relates to devices for turning flat cigarettes with a seam downward / provided with a tentacle that engages the seam.

In the proposed adaptation, the tentacles produce only the initial rotation of the cigarette, for the final turning which serves as an additional device in the form of a fixed stop or jet of compressed air supplied by the nozzle.

In the schematic drawing, FIG. 1 shows the proposed fixture with an emphasis at the moment when the tentacle begins to seize the seam; FIG. 2 - the same at the moment when the tentacle turned the cigarette in front of the stop; FIG. 3-the same at the time of the stop; FIG. 4 - the same at the time of tipping, cigarettes; FIG. 5 after the complete overturning of a cigarette; FIG. , b-

the form of making the device with the use of an air jet instead of a fixed stop, at the time of capturing a cigarette with a tentacle; FIG. 7 is the same at the moment of action of the air stream on a cigarette; FIG. 8-form of the device with the use of instead of a stop or a jet of air pressure plate in-moment capture tentacles cigarettes; FIG. 9 is the same at the time of raising cigarettes by half; FIG. 10th. at the moment of raising cigarettes in engagement with the tipper; FIG. 11 the same after tipping cigarettes; FIG. 12 - completely inverted cigarette during its further advancement; FIG. 13 is a modified device with a pressure plate at the moment of gripping a cigarette with a tentacle; FIG. 14- also at the beginning of the translational {eni

springs g, used to press the cigarettes to the fixed bar / s, the exact setting of the seam of the cigarettes relative to the tentacle (Fig. B-7).

5. The form of making the device according to claim 1, characterized in that the chain j links and conveyors are provided with spring-loaded pins / pulled off by a wedge e (Fig. T-5).

6. The form of the implementation of the device according to claim 2, characterized in that the tentacle is fixed on the rotary

the hinge step is pressed by the spring t to the cam eccentric 5L in order to return the tentacle to the reciprocal movement (Figs. 8-12). 7. The shape of the device according to claim 2, characterized in that the tentacle is fixed on the lever pivoting on the hinge and pressed by the spring S- to the stop d, to restrict the movement of the tentacle carried by the cigarette, serves as a second stop (Fig. 13-16) .

E1 centering s, and to the latter the lever r is attracted by the spring t. A spring-loaded lever A of the tentacles is attached to the end of the lever, the free end of which rests against the adjustable stop. The other end of the lever A bears on itself a part J of the tentacle engaging the seam of the cigarette. A press plate n is mounted on the machine bed, fixed on the spring V, swinging on the axis w and resting the free end on the stop, d; (Fig. 10 and 12). When a cigarette device works, it falls between the bar / f and the spring g, and if it is, the Seam is facing upwards, then the tentacle / lever h catches it Due to the movement of the links a with the cigarette in the direction of the arrow and the movement of the lever r in the opposite direction of the cigarette turns, clamping in a vertical position push bar l (Fig. 9 and 10). Upon further advancement of the conveyor, the cigarette tilts (Fig. 11) and then finally tilts (Fig. 12).

In another form (Figs. 13-16), the tentacle at the beginning of its work, in order to facilitate turning, takes a cigarette, does not rotate it until the cigarette leaves the pressure of the bar, which it rotates under the influence of the conveyor, stopped at that moment by a tentacle. The cigarette fi is supplied by the conveyor under the fixed thrust plate /, to which they are pressed by the spring acting from the bottom g. The feeler consists of springs A, A, which are suspended hingedly about the point o to the lever g, rotatably fixed on the axis of the g. The lever is held by the spring 2 in contact with the stop 9, while the spring A in the rest position touches the abutment. a support is attached to the frame of the machine, and the pressure plate l is fixed on the plank / pivotally. The cigarette lying incorrectly on the conveyor catches on the tip of the tentacle (Fig. 13) and presses the spring g. On the plank /, and as the links n continue to move in the direction of the arrow, the tentacle pulls the cigarette and moves it until

until the lever r rests against the stop {fig. 14). In this case, the cigarette is released from the bar / 1 and rotated by a tentacle, pressing the pressure plate l from above, under the action of which the final turning of the cigarette occurs (Fig. GB). Tentacles come to their original position under the action of spring s (Fig.). .

In the embodiment shown in FIG. 17-22, cigarettes af are supplied by links of the conveyor under the bar /, which prevents the cigarettes from turning incorrectly and guides them so that they fit flat, seam up or down. In this case, the strap / also serves as a limiter for the reverse movement of the spring L of the tentacle (Fig. 21). To turn the cigarette, a spring plate called a pin n is attached by a screw t. Instead of two spring plates 2 you can put one or more two springs located respectively along the length of the cigarette; the same remark applies to the number of tentacles.

The operation of the device of FIG. 17-22 is similar to the operation of the device of FIG. 1-5.

The subject of the patent.

1. A device for turning flat cigarettes with a seam downwards, provided with an engaging seam of cigarettes moving on a conveyor, with a tentacle, characterized in that in addition to a tentacle producing only the beginning of a rotation of cigarettes, an additional turning device was used for their final rotation, a fixed stop L (Fig. -5) or jet supplied by the nozzle t (Fig.6-7).

2. The modification of the tool according to claim 1, characterized by the use, instead of the stop k or the nozzle t, of the pressure plate n (Fig. 8-12).

3, Adaptation modification according to paragraph. 2, characterized in that the plate l is made spring (Fig. 17-22).
