The invention also relates to a device for conveying rod-shaped articles of the tobacco processing industry, comprising a device for transferring rod-shaped articles from a device for conveying rod-shaped articles in a transverse axial direction to a device for conveying rod-shaped articles in a longitudinal axial direction or vice versa, and comprising a device for conveying rod-shaped articles in a transverse axial direction and a longitudinal axial direction.
Background
Such devices and assemblies are used in particular in the tobacco processing industry for converting rod-shaped articles made of filter material and/or tobacco, such as filters, tobacco filters, filter segments, segment groups, cigarettes, tobacco rods or the like, using transport directions extending transversely to one another on the basis of the angular arrangement of the device for feeding rod-shaped articles relative to the device for transporting rod-shaped articles. In this case, rod-shaped articles, which usually have a circular or oval cross section, are selectively fed transversely to the longitudinal axis of the article to the transfer device and transported away longitudinally or vice versa. An example of a rod-shaped article for passing a transverse axial input and a longitudinal axial transport is an assembly for producing multi-segment filters.
The groups of at least two filter segments or a filter segment and a recess as a seat for the filter insert to be produced are normalized in the device for assembling the groups of filter segments and fed to the generic device for transferring rod-shaped articles from the device for assembling, for example, to the rod-forming device, by means of a row of rollers, which is usually a component of the device for assembling the groups. The constituent parts of the cylinder row are, for example, a collecting cylinder and a transport cylinder. By means of the roller rows, the rod-shaped articles reach further transport rollers, which can likewise be a component of the device for assembly, but are usually assigned to the device for forwarding the rod-shaped articles. The transport drum is operatively connected to an acceleration drum of the transfer device and transfers the rod-shaped articles conveyed in the transverse direction to the acceleration drum, by means of which the rod-shaped articles are conveyed in the transverse direction as well. The acceleration drum is in turn operatively connected to or can be operatively connected to a flexible format conveyor of the device for forwarding, from which rod-shaped articles can be received, wherein the rod-shaped articles are conveyed on the flexible format conveyor by means of the receptacle along the longitudinal axis thereof oriented on the running circumference. The rod-shaped articles are then lowered from the device for transfer, i.e. into the strip-forming device, at the lower apex S of the conveying means or of the running circumference.
By means of a strip forming device, the filter segments assembled in groups are enclosed with a wrapping paper and cut into the desired length of the final (multi-segment) filter. Position A for delivering rod-shaped articles from device for transferring to strip forming device2(corresponding to the storage position A)1) Is constant. In other words, the given position, i.e. the center of the strip in the strip forming device is fixed and lies in the horizontal plane E independent of the rod-shaped article's formatHIn (1).
The same applies in the same way only in the opposite direction if the device for conveying rod-shaped articles in the longitudinal direction, for example a rod-forming device, is an input device for rod-shaped articles to the device for transfer and accordingly in the plane EHDefining a storage position A for rod-shaped articles from the strip forming device to the device for transferring1. In order to feed the rod-shaped articles in the longitudinal direction to the device for transfer and to transfer the rod-shaped articles to the device for transporting the rod-shaped articles in the transverse direction, the transfer of the tobacco rod is mentioned as an example.
The length of the rod-shaped articles, i.e. for example the length of the filter or the length of the filter segments or segment groups, is also referred to as the format. However, the specification may be order-to-order different. In other words, it is often necessary to change the format, i.e. to change from a first product length to a second product length different from the first product length. The specification is changed because the rod-shaped article is on the plane EHIn a fixed storage position A1Or to give a position a2And forceThe same speed ratio is achieved and the diameter of the transport device is adapted, so that the transport device is flexible in size. In order to ensure the same speed ratio for all storage lengths or storage lengths of the rod-shaped articles when the rod-shaped articles are removed from or inserted into the rod, a diameter of the conveying means which is relevant to the specification or flexible in the specification is accordingly required.
In other words, different specifications of rod-shaped articles require conveying means having different diameter running circumferences. Preferably, a plurality of arms are arranged on each transport means, each of said arms having a receptacle arranged thereon. These receptacles describe the running circumference by the rotation of the insertion wheel. The adaptation of the running circumferential diameter of the delivery means can be carried out in different ways. A delivery instrument having a first operative circumferential diameter may be replaced with a delivery instrument having a different operative circumferential diameter. Furthermore, it is possible to replace the arm or the entire arm plate on which the plurality of arms are arranged with their receptacles. Another option provides for the arms to be adjusted in the radial direction with their receptacles. However, all the mentioned options result in a change of the spacing between the receptacle and the longitudinal conveyor. In order to prevent collisions (in the case of an increase in the running circumferential diameter) or to establish a functional connection (in the case of a decrease in the running circumferential diameter), the position of the flexible-format conveying appliance relative to the longitudinal conveyor must be adapted.
By varying the diameter of the conveying means, i.e. by varying the size of the running circumference described by the or each receptacle, the centre of the format-flexible conveying means, i.e. the axis of rotation I of the format-flexible conveying means and the receiving position a for rod-shaped articles, can be varied1Or to give a position a2In the plane EHThe spacing therebetween. In the known device for transferring rod-shaped articles, the transport drum, the acceleration drum and the flexible format conveying means are arranged on a common pivot arm which can pivot about a pivot axis. EP 2653043 a2 describes such a device for transferring rod-shaped articles. At the rotation axis I and the storage position A of the conveying appliance1Or to giveGo out of position A2In the case of a format change in the same sense of the change in spacing between the rollers, the entire pivoting arm, including all rollers and conveying means, pivots about a common pivoting axis in order to ensure that the lower vertex S of the running circle is located in the storage position A1Or giving position A2In (1). In other words, the height balance is performed by the swing. However, an incorrect positioning of the conveying means in the horizontal direction additionally occurs by the pivoting of the entire pivoting arm about the pivot axis. It is therefore necessary to pivot the conveying appliance about the second pivot point in order to reestablish the horizontal orientation and orientation of the conveying appliance relative to the articles. Such devices are structurally complex and disadvantageous in terms of adaptation to different specifications and the resulting multiple adjustment of the device.
Disclosure of Invention
The object of the invention is therefore to provide a simple and compact device for transferring rod-shaped articles, which ensures an accurate and simple adaptation to different specifications. The object of the invention is also to provide an assembly having such a device.
This object is achieved by a device of the type mentioned at the outset in that the flexible format conveying means is movably configured for adjusting the spacing independently of and relative to the acceleration drum. This means that, in order to adapt the device to different specifications, only the delivery means have to be adjusted. By only having to move a group of structures, i.e. flexible format conveying means, the structural construction of the device is significantly simplified and also made more rigid, thereby ensuring a more precise handover. Furthermore, by moving only the flexible format conveying means to change the pitch, said incorrect positioning of the conveying means in the horizontal direction is avoided.
A particularly preferred embodiment is characterized in that the acceleration drum is fixed in position with respect to the distance and cannot be arranged on the machine frame in a relatively adjustable manner, while the flexible-format conveying means are arranged on the support arm in a pivotable manner for adjusting the distance. With this configuration a particularly compact and rigid embodiment of the device is achieved.
Preferably, the flexible format conveying device is designed as an insertion wheel and can be pivoted about a pivot axis S for adjusting the spacing1Is supported in a swinging manner, wherein a swinging axis S1Oriented parallel to the axis of rotation I of the flexible format delivery instrument. Through the axis of oscillation S1And their orientation, enable a particularly short and therefore positionally accurate adjustment path, which enables precise transfer.
A preferred development is characterized in that the pivot axis S1Arranged at a distance from the axis of rotation I which corresponds approximately to the radius of the running circle. This configuration supports the aforementioned advantages.
Advantageously, the axis of oscillation S1Arranged in the region of the receiving position of the rod-shaped articles from the acceleration drum onto the conveying means or from the conveying means onto the acceleration drum. This configuration supports the aforementioned advantages.
Advantageously, the insertion wheel is assigned to a pivoting plate which is pivoted about a pivoting axis S relative to the support arm by means of a drive1The swing structure. In this way, the insertion wheel is not directly adjustable, but rather can be adjusted by or by means of a wobble plate, so that the adjustment is simplified and precise.
A suitable embodiment is characterized in that the conveying means are designed to be pivotable about a second pivot axis S2The position displacement is carried out in a pivoting or tilting manner. This alternative pivoting or tilting movement of the conveying means enables article-specific adaptation to articles of different strength, different hardness and different density. The tilting movement can increase or decrease the pressure exerted on the article, so that the transfer of the protected article is always ensured.
A preferred embodiment is characterized in that the second pivot axis S2Transverse to the first axis of oscillation S1And is oriented parallel to the axis of rotation II of the acceleration drum. Thus, the aforementioned advantages can also be achieved more simply and better.
Particularly preferred is an arrangement in which the second axis of oscillation S2Arranged at a distance from the axis of rotation II,the distance corresponds approximately to the radius of the acceleration drum. The aforementioned advantages are also better supported thereby.
An advantageous development is characterized in that the support arm is pivoted about the second pivot axis S relative to the machine frame by means of a drive2Can be pivoted. The tilting movement is not directly performed on the flexible conveyor, but rather by or by means of the second leg, so that the adjustment is simplified and precise.
This object is also achieved by an assembly of the type mentioned at the beginning in that the device for transferring rod-shaped articles is constructed and arranged according to one or more of claims 1 to 10.
Advantageously, the device for conveying rod-shaped articles in the transverse axial direction is a device for assembling groups of filter segments and the device for conveying rod-shaped articles in the longitudinal axial direction is a rod forming device.
