Description

Transfer device and trough drum and method for transferring hard filter elements

description

The invention relates to a trough drum for cigarette components, in particular hard filter elements, with receptacles for the components and inlets arranged in front of the receptacles in the conveying direction of the drum, and to a device for transporting cigarette components, in particular hard filter elements, with at least one feed device for feeding at least one component to at least one receptacle for the component which is moved by means of a conveying means. The invention further relates to the use of a bowl drum and a method for transporting cigarette components, in particular hard filter elements, wherein at least one component is transferred to at least one receptacle moved by means of a conveying means and at least one component Machine for the production of cigarettes or cigarette components, in particular multi component components.

For the production of cigarettes, it is necessary that filter pieces are attached to a tobacco rod and connected to it. Before cigarettes are finished, the filter pieces are manufactured in a separate device or machine. For the manufacture of cigarette filters, filter rods are made from different basic filter rods according to the desired properties of the filter.

For the manufacture of filter rods, various basic filter rods are cut and grouped and wrapped and cut in a filter rod machine. In particular, machines have proven themselves which can produce double filter rods, so that quadruple or six-fold double filter rods are produced at the end of the production process.

Crucial for the manufacturing process and the quality of the filter rods is a precise and gentle transfer of the filter elements or rods, so that special attention must be paid to this.

For the production of filter rods, basic filter rods are placed in separate filter magazines. These basic filter rods are usually in bulk, which must be separated, oriented and placed in rotating drums for installation in a filter with several segments in further process steps. For the production of multi-segment filters, hard filter elements are used, among other things. These hard filter elements usually consist of shock-sensitive and fragile materials. That is why the handling of transportation of fragile hard elements of great importance in filter production.

For the transport of filter elements, a filter removal drum is described in the patent DE 953 776, in which the troughs of the magazine drum are provided with egg nl surfaces which are tangentially inclined to the trough, so that filters can be removed from a fixed shaft. As a result of the inclined egg surface, the filters slide into the trough and are carried by it. The disadvantage here is that the filter elements experience abrupt impacts when they are removed from the shaft.

Starting from this prior art, it is an object of the present invention to improve the treatment and transfer of, in particular shock-sensitive, filter pieces in such a way that gentle treatment and rapid transfer of the filter pieces is made possible.

In a first solution to the problem, a trough drum for cigarette components, in particular hard filter elements, with receptacles for the components and in the conveying direction of the drum, inlet surfaces arranged in front of the receptacles is further developed in that at least two receptacles axially parallel to the axis of rotation and / or in the circumferential direction of the Drum are arranged offset from each other by a predetermined angle. Due to the staggered arrangement of the receptacles in the axial direction of the axis of rotation and / or in the direction of rotation, a plurality of filter pieces are removed from a feed device. The fact that many filter pieces are staggered during a full revolution of the drum, the rotational speed of the conveyor drum can be reduced so that the filter pieces in the receptacles or troughs can be deposited gently. The gentle placement significantly reduces the damage to the shock-sensitive filter elements. A large number of filter elements can thus be removed from filter magazines during a slow rotation of the trough drum, the filter pieces being treated gently as a result of the slow rotation.

In order to enable smooth takeover of cigarette components, the inlet surfaces arranged in front of the troughs are curved or straight, at least in sections. The design of the egg nl surface means that the filter elements to be carried can be brought gently to the system in the trough. Here, the inlet surfaces for different filter elements can be shaped differently.

For the removal of filter elements, it is advantageous if the heights of the receptacles essentially correspond to the diameter of the components or elements to be accommodated, so that after a component has been accommodated, the next or subsequent component can run along the circumferential surface of the drum. No impacts are thus exerted on this (subsequent) component and other damage is avoided.

The egg nl advantageously have lateral surfaces

Guide surfaces for the components so that a reliable guidance of the filter pieces towards the receptacle is ensured.

A safe entry into the receptacle or trough of the drum is achieved if the width of the egg surface and the width of the receptacles essentially correspond to the width of the components. This will cause tilting or made it impossible to twist when a component was transferred from a shaft to a receptacle.

Another solution to the problem consists in using a tray drum described above in a machine for producing cigarettes or cigarette components, in particular multi-component filters. Such bowl drums can be used in such machines instead of previous drums, so that there is a noticeable increase in quality in the manufacture of filters, since there is significantly less damage to the shock-sensitive filter pieces. All that is required is to replace the bowl drums. At the same time, according to a staggered trough drum. the invention, the productivity of a machine in the tobacco processing industry can be increased.

In the case of a graduated trough drum, for example, several (structurally) identical drums are disks, which over their circumference have several troughs with respective Ein! have surfaces at the same and predetermined (Tei 1 ungs) intervals, one behind the other so arranged that adjacent troughs of two drum discs are also arranged at a predetermined pitch apart. Overall, there is a helical distribution of the troughs on the drum. When determining the pitch, the geometry of a further drum is particularly important.

A third solution to the problem is proposed, in that a device for transporting cigarette components, in particular hard filter elements, with at least one feed device for feeding at least one component to at least one by means of a Conveyor moving receptacle for the component is further developed in that the feed device is movable. Due to the mobility or mobility of the feed device, filter pieces can be introduced into a receptacle in such a way that the sensitive filters can be introduced into the receptacle without damage. The mechanical load on the filter elements is thus significantly reduced. In the case of a receptacle formed on a rotatable conveyor drum, the direction of rotation of the drum must be observed in particular for guiding the movement of the feed device and gently placing the component in the receptacle.

Simple forms of movement are achieved when the feed device is linearly movable and / or pivotable. These movements are easy to implement and can be easily adapted to the funding.

A suitable drum for cigarettes or filter elements is a trough drum with corresponding receptacles for these components.

In a preferred development, the (cigarette) component can be guided along a circulation surface and / or inlet surface of the trough drum or the conveying means. This measure prevents the filter pieces from falling into the receptacles or troughs and being damaged as a result. Rather, the filter elements or components can roll on the circulation surface or the inlet surface until they are arranged in the receptacle. A rolling movement or rolling is much gentler on the cigarette components.

In order to provide good and reliable guidance when storing the components in a trough, the The feed device is arranged at a distance from the conveying means and / or the trough drum which is smaller than the diameter of the cigarette elements. The distance preferably corresponds approximately to the radius (half the diameter of the components) and less. Such a distance prevents the cigarette elements from falling out of the feed device before the transfer. In addition, the filter elements are stabilized or guided as they roll on the surfaces, so that the filter elements are deposited reliably and gently in the holder.

In a preferred development, the direction of movement or guidance of the feed device is designed such that the relative speed between the component to be accommodated and the receptacle is reduced when the component passes. Due to the reduction in the relative speed, the element to be picked up experiences a speed component from the feed device which is essentially aligned with the movement control of the pickup, so that the component gets into the pickup in a particularly gentle manner during the transition. Damage can be reduced, particularly with sensitive filter elements, which also increases the productivity of a machine and reduces the number of defective filter elements.

For a further solution to the problem, a method for transporting cigarette components, in particular hard filter elements, is proposed, at least one component being transferred to at least one receptacle moved by means of a conveying means by means of at least one feed device, which is further developed in that at least during the transfer the Component is moved by means of the feed device with respect to the receptacle or the conveying direction of the receptacle. The aim of the method is to gently place the filter elements from the feed device into the receptacles. The possibility of movement of the feed device in relation to the moving receptacle can reduce the relative speed between the cigarette component to be transferred and the receptacle. As a result, the cigarette components are placed in the receiving recesses in a particularly gentle manner.

In a further development according to the invention, the feed device is moved and / or pivoted linearly, in particular in the plane and / or direction of movement of the receptacle. Such a design enables simple construction.

It is also advantageous if the movement of the feed device and the direction of movement of the conveying means is influenced or designed such that the relative speed between the receptacle and the component is reduced during the transition of the component, so that the component is gently inserted into the receptacle becomes .

A gentle introduction of the component into the receptacle is achieved if the component is guided to the receptacle along an inlet surface.

For the transfer of cigarettes or cigarette components, trough drums have proven themselves in machines in the tobacco-processing industry for quick and gentle delivery, so that a trough drum is provided as a means of funding, which in a further development of Invention the component is conveyed or transported in a receptacle of a trough drum after the component has been handed over.

In order to prevent the cigarette components from falling out of the troughs of the drum, provision is also made for the component to be held in the receptacle by pressurization, in particular with negative pressure.

In a further development of the method, it is advantageous for multi-segment filter manufacture to transfer the component to at least one further conveyor device of a machine for producing cigarettes or cigarette components, in particular multi-component filters.

In addition, the object is achieved by a machine for producing cigarettes or cigarette components, in particular multi component components with at least one bowl drum according to the invention and / or the device described above.

The invention is described below by way of example without limitation of the general inventive concept on the basis of exemplary embodiments with reference to the drawings, to which reference is expressly made with regard to the disclosure of all details according to the invention not explained in detail in the text. Show it:

1 shows a device according to the invention in a detail 1;

Fig. Another view of a device and Fig. 3 shows an arrangement of conveyor drums.

Fig. 1 shows a device 1, in which by means of a feed 10 hard elements 11 from a magazine, not shown, into a trough 13 of a trough drum 18 (see FIG. 2), of which a drum segment 12 is shown. The bowl drum 18 rotates in the conveying direction D and has further bowls 13 on its circumference for receiving hard filter elements 11.

The trough drum 18 has a circumferential surface 15 arranged circumferentially over its circumference, on each of which the lowermost hard element 11 rolls in the feed 10 when the trough drum 18 rotates. The circumferential surface 15 merges into an egg surface 14a and a further egg surface 14b, at the end of which the receptacle 13 of the hollow drum is located. The bottom hard element 11 rolls after rolling on the peripheral surface 15 on the inlet surface 14a and then on the inlet surface 14b, the hard filter element 11 being slowly conveyed horizontally downward from the feed 10.

If the hard filter element 11 is gently inserted into the trough 13, the next hard element 11 rolls in the feed 10 on a further peripheral surface 15 of the trough drum formed after the trough 13.

For better adhesion of the filter elements 11 in the trough 13, each trough is provided with a suction hole 16, so that the element 11 adheres to the trough 13 by applying a vacuum. If a hard filter element 11 is received by a trough 13 when the trough drum 18 rotates, the next hard filter element 11 in the feed 10 can roll particularly gently on the peripheral surface 15 if the height of the trough 13 essentially corresponds to the diameter of the round filter elements 11. When the hard filter element 11 rolls on the egg nl surface 14a, 14b, the next filter element 11 is gently guided downwards in the feed 10 and can roll on the peripheral surface 15 arranged after the trough 13 while the drum 18 is rotated further.

By gently lowering the filter elements 11 in the feed 10, each hard filter element 11 is placed gently in the receptacle 13. In addition, the next filter element 11 is also continued gently. In order to make this possible, the feed 10 is arranged at a short distance from the peripheral surface 15 or the drum, the distance advantageously being less than the diameter of the filter elements 11. Particular stability is achieved when guiding the hard elements 11 if the distance is smaller than the radius (half the diameter) of the hard elements 11.

Of course, the On! surfaces 14a, 14b according to the requirements for the production of a multi-segment filter can be of different types, so that it is also possible that the inlet surfaces 14a, 14b can be curved at least in sections or can be straight. In order to give further stability when a filter element 11 enters the trough 13, it is provided that the trough drum or the drum segment 12 has a lateral guide 17 in the area of the inlet. A particularly gentle run-in and gentle treatment of the sensitive hard filter elements 11 is achieved if the feed 10 is arranged to be movable. In particular, the movement of the feed 10 should be designed so that the relative speed between the rotating receptacle 13 and the lower hard filter element 11 is reduced. For this purpose, the feed is moved in a plane of movement tangential to the plane of movement of the bowl drum 18.

In the context of the invention it is also provided that the feed 10 can move linearly. In an alternative, the feed 10 can also be designed to be pivotable. When guiding the feed 10, the direction of rotation D of the trough 13 or the trough drum 18 must be taken into account in particular. Above all, when the component 11 is received in the trough 13, the component can experience a speed (due to the movement of the feed 10) that is tangential to the direction of rotation D.

2 shows a further device 1, which has feeds 10 and a graduated trough drum 18 arranged next to one another.

In the graduated trough drum 18, adjacent troughs 13 are arranged axially parallel to the axis of rotation of the drum 18 and offset at a predetermined angle with respect to the axis of rotation. In the present exemplary embodiment, eight receptacles 13 are staggered in this way next to one another and one behind the other. The relay drum 18 rotates under feeders 10, from which the receptacles 13 receive hard filter elements 11 and transport them further into the troughs 13. The feeds 10 can be linear in the manner of movement described above or be designed to be pivotable in order to make the transfer as smooth as possible.

Such a staggered bowl drum 18 increases the insertion time for an individual hard filter element 11, in that the drum 18 rotates at a lower speed, but due to the staggering of the receptacles 13, a larger mass flow of hard filter elements 11 can be conveyed. For the mass flow, the speed of rotation and the pitch or pitch of the drum are decisive. In particular, the troughs 13 of the trough drum 18 are so screwed! arranged ini staggered that they correspond to a required drum tei 1 ung a subsequent drum.

FIG. 3 shows an arrangement of two parallel bowl drums 18, which simultaneously feed hard filter elements 11 through the parallel arrangement 18 to a further conveyor drum 20. Such a parallel arrangement enables higher production speeds to be achieved. The hard filter elements 11 passed on from the trough drums 18 to the conveyor drum 20 are positioned on the conveyor 20 by sliding elements 21. The object of the invention is particularly suitable for the production of multi-segment filters in filter manufacturing machines.

The present invention is particularly suitable for a "device for assembling groups of filter segments for the production of multi-segment filters of the tobacco processing industry and bowl drum", as disclosed in the same patent application, which was filed on the same day as the present patent application , Reference sign list
