Cigarette transport device for changing the direction and reducing the speed of cigarettes

The invention "relates to a locking and transport device for high-speed machines for the production of cigarette rods.

In modern high-speed cigarette-making machines, the rod travels at a speed of up to 12,700 cm / min _; and it is very conceivable that speeds may be doubled in the very near future. The continuous rod, while moving axially at these high speeds, is cut into desired cigarette lengths. All subsequent testing and packaging processes of the cigarettes are carried out more simply if the cigarettes move at right angles to their axes and are more closely spaced than they are if the direction of migration is from the longitudinal to the transverse direction without changing the distance from the center to the center Center point, as is changed by reducing the speed. This change in the direction of movement is more important for long cigarettes of, for example, 100 mm than for short cigarettes, of for example 25 mm.

It is therefore desirable to track the direction of travel of the cigarettes to change when they leave the station where the rod is cut to cigarette lengths and put them in slow enough so that while the number of cigarettes passing per minute is the same whose 'speed is slower and the distance between them is smaller.

Previously, these changes in direction and speed were brought about by stopping the cigarette suddenly if it is in a fluting or kut Moved on the periphery of a conveyor drum.

US Pat. No. 3,039,606 indicates the direction of movement of axially moving cigarettes by placing them on supports that are in a circular path tangential to the path of rod movement and about an axis transverse to the path of rod movement move. The orientation of the carrier is kept constant. Each cigarette moves with the wearer either by 90 ° or 270 °, i.e. to a point where the cigarette travels at right angles to its length and is there on you Donated sponsor.

The carrier according to the aforementioned US patent moves at practically the same speed as that in FIG cigarettes entering the mechanism. The speed is constant over the entire circular path of the carrier. The cigarettes therefore move with their delivery point from the mechanism according to the aforementioned US patent the same speed and at the same distance with which they entered although the movement on delivery is transverse rather than axial. Furthermore, the 2iga-

save their direction of movement at this delivery point in turn as a result of a curved groove or chute which necessarily exerts significant forces on any cigarette, to change their direction.

The apparatus constructed in accordance with the invention is a A plurality of carriers moving along an epicycloid trajectory. This varies on such a path Speed of the carrier cyclically between maximum and minimum values. Every cigarette gets through with his maximum speed moving carrier recorded, i.e. at practically the same speed as the axially moving cigarette. This speed will reduced to a minimum while the cigarette is held by the wearer, and the cigarette is then removed from given to the wearer, while the latter moves at its minimum velocity emotional. The braking forces acting on the cigarette are thus reduced to a minimum and thus the damage to the cigarette by such forces.

The invention is explained with reference to the drawings, in which

The following are the Pig. 1 to 6 described in detail:

-In the pig. 1 and 2 is a deflection crank drum 10 for clockwise rotation such as in Pig. 2 can be seen on a socket shaft 12 arranged. Drum 10 is driven by the attached gear 14 and carries a number rotating crank disks 16 which rotate clockwise about individual centers 24 when they are about the center of rotation 26 of the drum 10 describe its path. Each disk 16 is rotatable near its periphery stored suction bracket 20, which is constructed in the usual way to a pair of cigarettes 21 from the dispensing end of a continuous bar making machine to carry and transport. From Pig. 2 it follows that the center of rotation 22 of the suction bracket 20 'moves clockwise through the 6 o'clock position with respect to the center point 24, while at the same time the center point 24 moves clockwise through the 6 o'clock position with respect to the center point 26 emotional. The distance between the center 26 and the center 22 is therefore at a maximum, and

", ......, _ie ., .. ..: ,, .. BAD ORIGINAL

JFS 7446

the speed of the center point 22 is also at a maximum and takes place in the direction of the arrow P. When center point 24 moves 90 degrees clockwise to the 9 o'clock position about center point 26, it moves Center point 22 clockwise 270 ° around center point 26 to the 3 o'clock position. So if the midpoint is the 9 o'clock position reached and moves upwards, the center point 22 has reached the 3 o'clock position and moves with it Downward referring to midpoint 24, where the downward speed is different from the upward speed of the midpoint 24 is subtracted. By suitable selection of the radii 26, 24 and the radii 24, 22, the horizontal speed from 22, if, to 24 in the 6 o'clock position for example, 5 times the vertical speed of 22 when 24 is at the 9 o'clock position is located. A horizontal speed of 12,700 cm / min (5000 inches / min) at the 6 o'clock position becomes 2540 cm / min (1000 inches / min) vertical speed at the point of deposit on a transport drum 30, which is moving at a peripheral speed from 2540 cm / min (1000 inches / min). Drum 32 is part of a known tilting arrangement reproduced.

A drive mechanism for operating the deflection crank drum is in the Pig. 3, 4 and 5 reproduced. Drum 10 is rotatable on the turned down free end 34 of the nozzle shaft -12 fastened in a frame (not shown) stored. A stationary sun gear 38 is screwed to the end face of the shaft 12. A driven gear 36 is attached to an inner bearing bush 40 of the drum 10. A one-piece paddock 46, the radially outward from the left end of the bearing bush 40

009817 / U76

extends, as in Pig. 3 shown, rotatably supports a plurality of shafts 42 on which planetary gears 44, which are in engagement with the sun gear 38, festgek / .eilen are. Each shaft 42 is supported by a bearing 42a in the inner flange 46 and a second bearing 42b in one arm or leg 50, which extends inward from one to the Splash 46 attached ring 48 extends, supported. A plurality of bearing bushes 51 are attached to the arm 50, which each enclose one of the shafts 42 and to each of which a gear 54 is attached. V / elle 42 rotates with it Referring to gear 54, as can be seen, gear 54 acts as a sun gear in a secondary planetary system serves. Each V / Elle 42 has a one-piece crank flange which forms a disc 16. Every Disc 16 rotatably supports a shaft 56 on bearings 57. A Arm 18 carrying suction bracket 20 is attached to shaft 56. The disks 16 are on their periphery by bearings 53, which are seated in bores in the annular space 48.

At the end remote from arm 18, each shaft has a gear 58 attached to it. Each gear 58 meshes with idler gear 60 on the inner surface its associated disc 16 is rotatably mounted. The idler gear 60 meshes with the second Sun gear 54.

A suction effect is applied to the suction bows 20 through openings 62 which are in communication with a manifold 64, which in turn is in communication with an annular chamber 72 surrounding the shaft 58 through a line 66, a bore and a line 70. The annular chamber 72 is defined by a radial bore 74 with a passage 76 extending axially through the shaft 42,

in connection. The passage 76 int with a chamber 78
in a cuff 80 provided with an opening 82
connected to the right view of the drum 10. Every
Shaft 42 is provided with a separate collar 80 which
has its own opening 82, in communication. Opening 82 occasionally engages in a curved slot 84 which is formed in an annular space formed as a stationary space
Shoe 86 is formed in connection via tube 88 with
a vacuum source, not shown.

As shown in Figure 4, the arcuate slot 84 begins at the 6 o'clock position and extends in a clockwise direction up to the 9 o'clock position.

From Figs. 3, 4 and 5 it can be seen that when
Drum 10 rotates around the stationary sun gear 38, the shaft 42 driven by the drum 10 rotates with the drum and also rotates with respect to Trorr, -mel 10 as a result of the movement transmitted by the planetary gear 44. This causes shaft 56 to both
on a track around the shaft 34 as well as around the shaft 42
emotional. As shaft 56 moves in a path about shaft 42, it rotates in a direction opposite to that on shaft 56 due to the action of sun gear 54, idler gear 60 and gear 58 on shaft 56
Rotational movement of the shaft 42. The gear ratios are such that the spatial orientation of the suction bracket 20 is kept constant when it is on a path around the axes
24 and 26 moved.

Curve. The cigarettes are referenced in the 6 o'clock position taken on the center point 26 and are released in the 9 o'clock position. The migration speed takes place in the 6 o'clock position of the center point 22 with respect to the center point 24 in the same direction as the migration speed of the center point 24 with respect to the center point 26, so that the migration speed of the center point 22 reaches its maximum at the 6 o'clock position. In the 9 o'clock position is * the speed of migration of the center 22 with respect to the center 24 in the opposite direction Direction of the speed of migration of the center 24 with respect to the center 26, and thus the absolute speed of the center 22 with respect to a fixed support at its minimum value. The horizontal speed of cigarettes 21 is at a maximum when they are in the 6 o'clock position, and it decreases to 0 at a point 27 where a tangent to curve C would be vertical. At the 9 o'clock position the tangent to the curve C again runs vertically, so that the horizontal speed of the cigarettes 21 and thus whose speed in the direction of their axes is equal to 0. At this point it is preferred to use the cigarettes the carriers 20, since their absolute speed is then at a minimum. The acceleration of the cigarettes is also at a minimum at the 9 o'clock position, so that this position is the optimal point at which the cigarettes are to be expelled from the carriers.

It should be noted that the Seheiben 16 go through three revolutions, while the drum 10 goes through one revolution. Alternative arrangements can be devised in which the ratio of the revolutions of the disks 16 to the revolutions of the drum 10 is any multiple of three. . .

The following are the Pig. 7 "to 9 in detail":

In that pig. are parts that have their counterpart in the Pig. 1 to 6, denoted by the same reference numerals and are not described further.

This pig. explain an alternative embodiment of the invention including a drum 130 which rotates on a shaft 132. The drum 130 includes a bearing sleeve 134, which is mounted on the shaft 132 by means of a bearing 136. The bearing bush 134 has a radial Splash 138 on, on a first peripheral cylinder 140 is fastened by means of screws 141. The cylinder 140 is connected to another peripheral cylinder 114 by means of Screws 142 connected.

A first sun gear 94 is keyed to the shaft 132 and is connected to a plurality of planetary gears 95 in engagement, each of which is mounted on a shaft 97. Each shaft 97 carries at its left end, as can be seen from Pig. 7 results, a disc 16 in which a shaft 56 is rotatably mounted, which carries an arm 18, which in turn has a Vacuum cigarette carrier 20 carries. Each shaft 97 is in a bearing 99 in the flange 138 and in another bearing 101 rotatably mounted in an arm 92 connected in one piece to the cylinder 140.

Mounted .on the left end of shaft 132 is a second sun gear 96, with a plurality of intermediate gears 104 (see Pig. _9.) Is engaged on the

009817 / U76

SAO OBtGlNAt

JPS 7446

Arm 92 rotatably mounted. Each idler gear 104 is stationary with another intermediate gear 102 in engagement, which is also rotatably mounted on the arm 92 and with a planetary gear 100 is engaged on the periphery of a sleeve 98 which is rotatable on one of the shafts 97 is stored. The sleeve 98 carries an internal gear 108 which cooperates with a gear 110 on the shaft 56 to maintain the angular position of shaft 56 constant as the drum rotates.

The left end of the drum has what appears to be from Pig. 7 results, "an annular member 114 with an arm or web 116, the one with suitable openings 120 for the sleeve 98 and the Splash 16 of waves 97 is equipped.

As the drum 130 rotates about the shaft 132, the shafts 97 become the ones with the planetary gears 95 due to the Sun gears 94 are engaged, rotated, and the shaft 56 rotates to maintain its spatial orientation due to the sun gear 96j the planetary idler gears 104, 102, 100 and 108 on sleeve 98 and the drive wheel 110 mounted on shaft 56. It should be noted that the Axis of the drive wheel 110 moves around the axis of the sleeve in the same direction of rotation as the sleeve 98 rotates about the sun gear 96 due to their movement. However, the difference in the proportions is such that a relatively reverse rotational movement of the drive wheel 110 with respect to the shaft 56 results. From Pig. 9 it can be seen that the gear 110 actually rotates counterclockwise (that is, maintains its spatial orientation) when whose axis is in the direction of arrow G with greater angular velocity than the rotational movement in the direction of Sleeve 98 moves. For example, in an execution

form of the invention a ratio of 2: 1 between that Sun gear 94 and planetary gear 95, a ratio of 1: 1 between sun gear 96 and gear 100 and a ratio of 3: 1 is set between the internal gear 108 and drive gear 110. These relationships create those in the Pig. 2 to 6 explained rotary movements.

The main advantage of moving the cigarette carriers along an epicycloid trajectory is that a such a path by a crank or other rotary element which moves at a constant angular velocity moved, generated and thus not subject to any angular acceleration or deceleration. So while the Carrier itself is decelerated by reducing its speed significantly with respect to a stationary point becomes, regardless of this, the rotating part on which the carriers are supported rotates continuously with a practical one constant angular velocity continues, and there is no need to use energy to accelerate it to spend still absorbing energy to slow it down.

The same result, that is, the movement of a point at variable speed on a limb that is ^ itself with -rotating a constant angular velocity can, on the other hand, be achieved by using a mechanism that creates a cycloid or hypocycloid path in place of the illustrated epicycloid path. This result can also use some mechanisms to create an elliptical orbit and possibly other curve configurations can be achieved.

However, these results are considered to be most beneficial and to bring about benefit by a mechanism which, as discussed, creates an epicycloidic pathway.
