Definitions
- the tobacco is fed in a continuous flow towards a clipping and compression device where a regular tobacco rod is formed before being covered with cigarette paper and then cut into individual cigarettes.
- a regular tobacco rod is formed before being covered with cigarette paper and then cut into individual cigarettes.
- the tobacco flow in the device it is first compressed locally and then the amount of tobacco exceeding that necessary for the preparation of the rod is eliminated by a clipping device.
- a device for controlling the flow of tobacco according to the invention is arranged upstream of the clipping and compression device.
- the clipping and compression device 1 visible in FIG. 1, corresponds to that described in the patent application mentioned above; it mainly consists of an endless belt 10, driven in translation between the two pulleys 10a and 10b, any one of these pulleys being rotated by a motor not shown in the figure, a compression cam 11 and two rotary knives 12 clipping the excess tobacco.
- This tobacco 2 comes from an intermediate stock 13 from which it is sucked through the belt 10, so that the tobacco strands come together against the belt 10, forming a layer 20, limited in width by two side rails 14 and 15 (visible in Figures 2 and 3).
- the layer 20 is irregular, that is to say that its thickness is uneven; if there was no flow control device before the cam 11, it would act sometimes on a thin layer, sometimes on a layer of greater thickness, which would lead to irregularities in the segments densified by the cam 11, of the output flange 21.
- the flow control device 3 consists of a motor 30, which can be electric, pneumatic or hydraulic, rotating at constant speed and connected by a clutch 31 to a disc 32 of cylindrical shape rotating in a plane arranged perpendicular to the irregularities of the layer 20, around an axis of rotation arranged perpendicular to the direction of advance of said layer.
- the upper circular circular face 32a of the disc 32 is located in a plane just below the lower faces 14a and 15a of the side rails 14 and 15, while as seen in Figure 3, the axis of rotation of the disc 32 is offset from the line of passage of the layer so that the layer 20 is intercepted by a portion of the outer cylindrical surface 32b of the disc 32 located proximity to the place where this outer cylindrical surface 32b moves parallel to the layer 20 and in the same direction as it.
- the portion of the surface 32b intercepting the layer 20 deflects the part 22 of the layer 20 located below the upper circular surface 32a.
- the speed of rotation of the disc 32 is such that the peripheral speed of the cylindrical surface 32b is close to the speed of translation of the layer 20, the excess tobacco strands 22 are delicately separated from the layer 20, without being torn off or torn; this surplus tobacco is eliminated by the side of the disc 32 and falls on a transport device which can be a belt transport device 16a and 16b where it is mixed with the surplus tobacco 23 eliminated by the clipper 12 in order to be recycled and returned to the intermediate stock 13.
- said layer has a regular thickness, determined by the distance separating the belt 10 from the upper circular surface 32a.
- this thickness it is necessary that the minimum thickness of the layer 20, before it passes over the disc 32, is always greater than said regulated thickness.
- the cam 11 acts to compress a segment of the layer, it always acts on the same thickness of this layer, which makes the density of the tobacco of the different compressed segments of the final roll uniform. 21.
- the clutch coupling 31 is located between the engine 30 and the disc 32; it is indeed necessary, during the launching of the machine, to cause the disc 32 to rotate at a speed such that its peripheral linear speed is approximately the running speed of the layer 20; thereafter, the friction of the lower face of the layer against the upper circular surface 32a is sufficient to drive the disc 32 at good speed; it is therefore possible to decouple the drive of said disc by the clutch coupling 31 and to cut off the supply to the motor 30. It is understood that it is quite possible to provide an embodiment of the device according to the invention does not include this declutching, the disc 32 remaining continuously driven by the motor 30.
- the speed of movement of the layer of tobacco in a machine of the type described is of the order of 500 to 1000 m / min.
- the disc In order to have a regular separation of the surplus 22 from the tobacco layer 20, various precautions must be taken with regard to the geometry of the disc as well as its constituent material; in particular the outer cylindrical surface 32b of the disc 32 must be arranged perpendicular to the direction of passage of the layer 20 in order to correctly eliminate the excess 22 from the side; misalignment of this surface 32b, in one direction or the other, would lead to a slight compression or depression of the layer of controlled thickness, which would harm its regularity.
- the material of the disc must be chosen so that the tobacco particles do not adhere to the disc, for this, according to a preferred embodiment, the disc is made of POLYDUR (registered trademark of LEDER & Co.
- the disc can be made of any material covered with a layer or a coating on which the tobacco does not adhere.
- the surface condition of the faces 32a and 32b of the disc is absolutely smooth.
- the tobacco flow control device according to the invention has been described mounted just before a clipping and compression device in which the tobacco flow is sucked against a belt which moves it; other clipping and compression systems exist on which the device according to the invention can equally well be applied. More generally, whatever the geometry according to which the tube is formed, the device according to the invention can be applied to adjust the thickness of said tube. Similarly, the device can be applied to any device for clipping and reinforcing the sausage requiring regulation of the thickness of the layer of tobacco before reinforcement and clipping, regardless of the way in which the strengthening of the ends of cigarettes is carried out. .
- the device for controlling a flow of tobacco according to the invention is particularly suitable for regulating the thickness of a layer of tobacco of irregular thickness, before it enters the reinforcement or compression device, so that the segments of the sausage having a higher density all have the same density.
- the device according to the invention eliminates the surplus of tobacco without the latter being damaged.
- the introduction of such a device in a machine for making the rod of tobacco from cigarettes or other articles of the tobacco industry allows a more regular production, as well as an increase in quality. finished products by reducing waste.
