Description

[0001] The invention relates to a device for transporting rod-shaped articles of the tobacco processing industry with a rotating conveying element, preferably a drum body, and a carrier, wherein the conveying element can be detachably connected to the carrier by means of a clamping device, wherein the clamping device has at least one drive element, such that at least one holding element changes position transversely to the direction of movement of the drive element by a movement of the drive element.The invention further relates to a machine of the tobacco processing industry and the use of a clamping device in a device for transporting rod-shaped articles of the tobacco processing industry with a rotating conveying element, preferably a drum body, and a carrier, wherein the conveying element can be detachably connected to the carrier by means of the clamping device, wherein the clamping device has at least one drive element, such that at least one holding element changes its position transversely to the direction of movement of the drive element by means of a movement of the drive element.

[0002] Conveyor drums are used, for example in filter-applying machines, to transport rod-shaped smoking products, filters, filter sticks, tobacco sticks, or cigarettes or filter cigarettes. The conveyor drums consist of a stationary control body on which a drum body is mounted, rotating and driven by a drive shaft. When installing or removing drum bodies from the filter-applying machine, for example during a format change or for cleaning, the drum bodies are pulled off the control bodies. To do this, the operator loosens several screws to remove the drum body from the control body and attach a new drum body, for example, for cigarettes with a different diameter or length.

[0003] US patent 4,438,774 describes a cigarette conveyor drum in which the drum body is attached to the rotating shaft by means of a thumbscrew. To replace the drum body, the retaining screw is loosened manually so that the drum body can be removed from the control body.

[0004] German patent DE 101 16 684 A discloses a device with a rotating driven unit, in particular a drum, in which an inner hub and an outer hub are connected to each other by means of rotating clamping rings. An axially directed pressure deforms the clamping rings into a clamping position, thus establishing a connection between the inner hub and the outer hub. Overall, this mechanical clamping element is very complex in its design.

[0005] From EP 1 518 468 A2, a device for transporting rod-shaped articles of the tobacco processing industry is known, wherein a rotating conveying element, preferably a drum, and a carrier are provided, wherein the conveying element can be detachably connected to the carrier by means of a clamping device, wherein the clamping device has at least one drive element, so that by a movement of the drive element at least two, preferably three, retaining elements change their relative position to each other transversely to the direction of movement of the drive element.

[0006] This allows for quick replacement of a drum body using tools, while keeping the design effort to a minimum.

[0007] The object of the present invention is to provide a device for transporting rod-shaped articles of the tobacco processing industry, a machine with such a device and the use of a clamping device in such a device in order to enable very fast and efficient changes of drum bodies, in particular without further aids, so that a very variable handling of the machine is possible in the operation of a machine of the tobacco processing industry.

[0008] This problem is solved by a device for transporting rod-shaped articles from the tobacco processing industry, comprising a rotating conveying element, preferably a drum body, and a carrier. The conveying element is detachably connected to the carrier by means of a clamping device, the clamping device having at least one drive element such that a movement of the drive element causes at least one retaining element to change position transversely to the direction of movement of the drive element. This clamping device is further developed by the fact that the drive element is manually driven or can be driven via a handle, in particular one attached to the conveying element. Because the drive element is manually driven or can be driven via a handle, conveying elements, especially drum bodies, can be quickly exchanged without tools that could be lost or are not always readily available.

[0009] Preferably, the drive element can be driven without tools or is driven. In particular, it is provided that no tool engagement is required in the conveying element for replacing the conveying element. For example, unlike the prior art, no internal hexagon socket is provided into which a hexagon key can be inserted to connect a conveying element to a carrier by actuating this tool.

[0010] Preferably, the drive element comprises a screw connected to the handle via a device that limits the torque on the screw. The handle together with the screw or drive element preferably forms a torque screw.

[0011] The handle can be designed as a torque handle.

[0012] Preferably, the limit value for the torque is in a range of 0.5 Nm to 10 Nm, in particular 1 Nm to 8 Nm, in particular 2 Nm to 6 Nm, preferably in a range of 3 Nm to 5 Nm.

[0013] Preferably, the torque of the device limiting the torque on the screw is adjustable or provided with a fixed, predetermined torque. The fixed, predetermined torque is preferably in the range of 0.5 Nm to 10 Nm, in particular 1 Nm to 8 Nm, in particular 2 Nm to 6 Nm, and preferably in the range of 3 Nm to 5 Nm.

[0014] Preferably, the clamping device comprises a tension spring that presses against a retaining element, wherein a longitudinal axis of the tension spring is arranged, in particular, collinear with or parallel to the direction of movement of the drive element. The tension spring presses against the drive element via a retaining element, which may be designed as a ball, preferably in a direction corresponding to an axis or longitudinal axis of the drive element or a direction of movement of the drive element. The longitudinal axis is the axis in the direction of which the drive element can be moved. Preferably, the longitudinal axis is perpendicular to a rotational axis of the drive element or a rotational axis of the conveying element.This measure ensures that the retaining element, in particular a centrally arranged retaining element, especially a retaining ball, is always pressed towards a neutral position, so that the retaining element(s), which changes position transversely to the direction of movement of the drive element, can safely slide into the center when the clamping device is to be released.

[0015] Preferably, the retaining element or elements can be inserted into a receiving socket of the carrier, the carrier in particular comprising a drive flange.

[0016] In one embodiment, the retaining element or elements are captively inserted into the receiving socket of the carrier.

[0017] Within the scope of the invention, the term captive includes the fact that the retaining element(s) are arranged in a cage of a housing or in a receiving socket, wherein through-openings are smaller than the retaining elements, particularly in cross-section.

[0018] In one embodiment, three or four retaining elements are provided.

[0019] Preferably, the support is screwed to the drive flange. In particular, it is possible to clean the retaining element(s) after removing the conveying element from the support. In one embodiment, when the conveying element is mounted, the support and the retaining element(s) arranged in the support are encapsulated.

[0020] Preferably, the at least one retaining element or the at least two retaining elements, in particular three or four retaining elements, are arranged in a first housing, in particular in a captive manner. Preferably, the first housing can be designed as a cylinder, in particular a clamping cylinder.

[0021] In one embodiment, a visual indicator is provided so that the operator can determine whether the conveying element is connected to the carrier. For example, a visible marking can be provided between the handle and the drive element. This marking is visible between a second housing, to which the handle is attached, and the handle itself when the drive element is still loose (i.e., in an untensioned state). When the drive element is engaged (i.e., when the clamping device is engaged), this visible area disappears into the second housing. This allows the operator to determine whether the conveying element is connected to the carrier or not.

[0022] Preferably, balls are provided as retaining elements. In particular, one embodiment provides three or four balls, which allows for the compensation of tolerances and deviations in the concentricity of the balls. This makes it possible to achieve a secure connection at a predefined torque.

[0023] In one embodiment, the drive element and / or the handle is or are mounted in a second housing, wherein the second housing is connected to the conveying element, in particular at an end face of the conveying element.

[0024] In a further embodiment, a positive-locking connection between the conveying element and the support is provided via the retaining element(s). This provides a particularly secure connection between the conveying element and the support.

[0025] To enable a positive-locking connection, the second housing has an internal recess into which the retaining element engages. Preferably, this is a clamping connection. The recess can also be provided as a circumferential groove. In this case, the connection is a friction-locking connection in the radial direction and a positive-locking connection in the axial direction. Within the scope of this application, "positive-locking" refers in particular to a positive-locking connection, a friction-locking connection, and / or a friction-locking connection.

[0026] In one embodiment, the drive element is designed to be axially movable. In another embodiment, the handle is arranged on an end face of a second housing.

[0027] In a further embodiment, an end stop for a retaining element is provided in the first housing in order to limit the travel distance of the retaining element when a drive element is retracted or when a conveying element is removed.

[0028] This ensures a defined position for the retaining element when the drive link is released or removed. In particular, this feature also prevents the retaining elements from being lost within the first housing.

[0029] Preferably, two end stops are provided which limit the movement of the holding element(s) in the axial direction.

[0030] It is particularly advantageous if the handle remains attached to the conveyor element after it has been removed from the carrier. This allows for a particularly quick, safe, and efficient replacement of conveyor elements.

[0031] In one embodiment, a lock nut is provided by means of which the rotary handle can be detachably fixed. Preferably, the lock nut is mounted on the same axis as the rotary handle and clamped against the rotary handle. Preferably, the lock nut is a knurled nut.

[0032] The problem is further solved by a machine of the tobacco processing industry, in particular a filter assembly machine or filter assembly device or a multi-segment filter manufacturing device with a device according to the invention, which has been described above.

[0033] It is particularly preferred if at least four, preferably at least five, devices of the type according to the invention are provided in the machine. This allows for very rapid format changes in a machine used in the tobacco processing industry.

[0034] In particular, it is preferred if each conveying element of a, in particular complete, filter segment run from a removal drum to a delivery drum, wherein the delivery drum is designed to discharge the filter segments onto a assembling drum, is equipped with a device according to the invention.

[0035] Preferably, a cutting drum and / or a dispensing drum incorporates a device according to the invention. This is particularly preferred because these types of drums require more frequent cleaning than, for example, push or collating drums.

[0036] Preferably, at least one, and preferably several, vent holes (72) are provided, particularly in the second housing (63). This very efficiently prevents air build-up during the exchange of conveying elements, especially drum bodies.

[0037] Preferably, the device includes a lock nut, in particular a knurled nut, which prevents the handle, especially the torque handle, from being accidentally loosened. The lock nut, in particular a knurled nut, thus serves as a locking or counter-locking mechanism for the drive element and the handle.

[0038] Preferably, an adjustable rotatable ring is provided on the second housing, by means of which the locking position of the lock nut, in particular a knurled nut, adjacent to the adjustable rotatable ring, can be visually indicated. For this purpose, a marking, in particular a scale mark, is preferably provided on the circumference of the adjustable rotatable ring. Several scale marks may also be provided here to indicate the state or progress of the rotation of the lock nut, in particular a knurled nut. The lock nut, in particular a knurled nut, preferably also has a marking, in particular a scale mark. This makes it very easy to see whether the clamping device has tightened the device, i.e., is closed, or not tightened, i.e., is open.

[0039] Furthermore, it is provided that an additional bolt secures the lock nut, in particular a knurled nut, and preferably also limits the maximum rotational travel of the lock nut, in particular a knurled nut.

[0040] Furthermore, the handle is preferably radially extended to such an extent that it fits into a bore of the lock nut, in particular knurled nut.

[0041] In one embodiment, a retaining ring is preferably provided in an inner groove of the lock nut, in particular a knurled nut, which prevents the handle from being unscrewed or pulled out of the area of ​​the inner bore of the lock nut, in particular a knurled nut.

[0042] In one embodiment, the drive element is made of a hardened material in the direction of the retaining elements or has a pressure pin there, which is preferably inserted axially into the drive element at its end face. The pressure pin is preferably made of hardened steel or another hardened material.

[0043] The problem is further solved by using a clamping device in a device for transporting rod-shaped articles of the tobacco processing industry with a rotating conveying element, preferably a drum body, and a carrier, wherein the conveying element can be detachably connected to the carrier by means of the clamping device, wherein the clamping device has at least one drive element, such that by a movement of the drive element at least one retaining element changes its position transversely to the direction of movement of the drive element, which is further developed by the fact that the drive element is driven or can be driven via a handle, in particular attached to the conveying element.

[0044] In one embodiment, the drive element can be driven or actuated without tools.

[0045] In one embodiment, the drive element comprises a screw which is connected to the handle via a device limiting the torque on the screw.

[0046] In one embodiment, the clamping device comprises a tension spring which presses against a retaining member, wherein a longitudinal axis of the tension spring is arranged in particular collinear with or parallel to the direction of movement of the drive member.

[0047] In one embodiment, the retaining element or at least two retaining elements can be inserted into a receiving socket of the carrier, wherein the carrier in particular comprises a drive flange.

[0048] In one embodiment, at least one retaining element or at least two retaining elements are arranged in a first housing, in particular in a captive manner.

[0049] In one embodiment, balls are provided as retaining elements.

[0050] In a further embodiment, the drive element and / or the handle is / are mounted in a second housing, wherein the second housing is connected to the conveying element, in particular at an end face of the conveying element.

[0051] In one embodiment, a positive-locking connection between the conveying element and the carrier is provided via the retaining element or retaining elements, wherein in particular the second housing has an internal recess into which the retaining element engages in a functionally connecting manner.

[0052] In one embodiment, an end stop for a retaining element is provided in the first housing in order to limit the travel distance of the retaining element when a drive element is retracted or when a conveying element is removed.

[0053] In one embodiment, the handle remains attached to the conveying element even after it has been removed from the carrier.

[0054] The torque handle that can be used according to one embodiment can, for example, be a torque handle from Erwin Halder KG, with order number EH 24710 or EH 24711. The torque handle can also be from Heinrich Kipp Werk GmbH & Co. KG. In this case, the torque handle incorporates an integrated torque mechanism that allows for mechanical torque limitation, for example, via a detent. An electric torque handle can also be used. In this case, it is advisable to include a battery in the torque handle.

[0055] In one embodiment, a drum quick-release fastener or a conveyor element quick-release fastener is provided for a device for transporting rod-shaped articles in the tobacco processing industry. Preferably, an existing threaded bore in a support, particularly a drive flange, is used. A screw bolt, on which a first housing is arranged, can be screwed into the existing threaded bore. The first housing can accommodate at least one retaining element or at least two retaining elements, preferably three or four. The existing threaded bore in the support or drive flange is preferably collinear with the axis of rotation of the drive shaft.

[0056] For connecting a second housing, into which a drive element (manually driven or driveable via a handle) is mounted on the conveying element, existing through holes in the drum body, particularly the end face of the drum body, can be modified with an internal thread, or threaded inserts can be installed into which fastening screws can be inserted. This allows the second housing to be attached or mounted, particularly to an end face of a conveying element, especially a drum body.

[0057] In one embodiment, the second housing is connected to the conveying element, in particular at the end face of the conveying element.

[0058] A torque handle, which slips at a specific torque, allows a predetermined torque to be applied to the system or device. This axial force is used to clamp the conveying element to the carrier or drive shaft via an axially guided retaining element, particularly a ball, and a radially connected retaining element, also particularly a ball, to the axially guided retaining element. When tightened, the axially guided retaining element is axially displaced and thus interacts with at least one radially arranged retaining element, causing at least the other radially arranged retaining element to be radially displaced. These elements clamp against, in particular, an inner radius of the second housing after a defined or predetermined path. This creates a fluid connection.A retaining element is positively engaged in a recess of the second housing. This secures the conveying element axially and / or radially on the carrier or drive shaft. The single axially guided retaining element can also be replaced by the end of a drive element, which is preferably hemispherical. Preferably, two radially arranged balls are used so that tolerance deviations in the concentricity of the balls can be compensated for.

[0059] Preferably, at least one, and preferably several, vent holes (72) are provided, particularly in the second housing (63). This very efficiently prevents air build-up during the exchange of conveying elements, especially drum bodies.

[0060] Preferably, the device includes a lock nut, in particular a knurled nut, which prevents the handle, in particular the torque handle, from being accidentally loosened. The lock nut, in particular a knurled nut, thus serves as a locking or counter-locking mechanism for the drive element and the handle. Preferably, an adjustable rotatable ring is provided on the second housing, by means of which the locked position of the lock nut, in particular a knurled nut, adjacent to the adjustable rotatable ring, can be visually indicated. For this purpose, a marking, in particular a scale mark, is preferably provided on the circumference of the adjustable rotatable ring. Several scale marks may also be provided here to indicate the status or progress of the rotation of the lock nut, in particular a knurled nut. The lock nut, in particular a knurled nut, also has a marking, in particular a scale mark.This makes it very efficient to see whether the clamping device has clamped the device, i.e., is closed, or whether it has not clamped the device, i.e., is open.

[0061] Furthermore, it is provided that an additional bolt secures the lock nut, in particular a knurled nut, and preferably limits the maximum rotational path of the lock nut, in particular a knurled nut.

[0062] Furthermore, the handle is preferably radially extended to such an extent that it fits into a bore of the lock nut, in particular knurled nut.

[0063] In one embodiment, a retaining ring is preferably provided in an inner groove of the lock nut, in particular a knurled nut, which prevents the handle from being unscrewed or pulled out of the area of ​​the inner bore of the lock nut, in particular a knurled nut.

[0064] In one embodiment, the drive element is made of a hardened material in the direction of the retaining elements or has a pressure pin there, which is preferably inserted axially into the drive element at its end face. The pressure pin is preferably made of hardened steel or another hardened material.

[0065] Further features of the invention will become apparent from the description of embodiments according to the invention, together with the claims and the accompanying drawings. Embodiments according to the invention may fulfill individual features or a combination of several features.

[0066] The invention is described below, without limiting the general concept of the invention, with reference to exemplary embodiments and the drawings, whereby for all details of the invention not explained in detail in the text, explicit reference is made to the drawings. The drawings show: Fig. 1 a schematic representation of drum runs of a multi-segment filter manufacturing device, Fig. 2 a schematic three-dimensional view of a device for transporting rod-shaped articles according to the prior art, Fig. 3 a three-dimensional schematic representation of a device according to the invention for transporting rod-shaped articles, Fig. 4 a schematic sectional view of a section of the device according to the invention in a schematic representation, Fig. 5 a schematic three-dimensional representation of another device according to the invention, Fig. 6 a schematic sectional view of the device made of Fig. 5 , Fig. 7 a schematic three-dimensional representation of the facility made of Figs. 5 and 6with the omission of elements, Fig. 8 a schematic sectional view of a section of an embodiment of the device according to the invention, and Fig. 9 a further schematic sectional view of a part of an embodiment of the device according to the invention.

[0067] Within the scope of the invention, features marked with "in particular" or "preferably" are to be understood as optional features.

[0068] In the drawings, identical or similar elements and / or parts are provided with the same reference numbers, so that a re-presentation is omitted.

[0069] Fig. 1Figure 10 shows a schematic representation of a drum run of a multi-segment filter manufacturing device 10. In a filter segment assembly device 18, filter segments of multiple usable lengths are taken from magazines (not shown) by a removal and cutting drum 11 or 11'. There, the filter segments are cut, for example, twice, as shown by the two indicated cutting blades or circular blades.

[0070] The cut filter segments are then staggered in a staggered drum 12, 12' and staggered again in a further staggered drum 13, 13'. The filter segments thus staggered are then aligned on a sliding drum 14, 14' and discharged onto a transfer drum 15. Drums 11 to 14 and 11 to 15 can be designated as the first filter segment run 34, and drums 11' to 14' and 11' to 15' as the second filter segment run 34'.

[0071] The filter segments transferred from the first filter segment run 34 to the transfer drum 16 are passed on to the assembly drum 15', where the filter segments from the second filter segment run 34' are combined with the filter segments from the first filter segment run 34. For example, the filter segments from the second filter segment run 34' can be added to the filter segments from the first filter segment run 34 or combined with them in some other way.

[0072] To securely hold the filter segments or filter elements, the drums have receiving recesses, which are not shown here. The filter segment group assembly device 18 can also have further corresponding drum runs of the same or similar design, for example, to provide additional filter segments within the group of filter segments. For example, a transfer drum 17, shown with dashed lines, is provided for this purpose, which discharges or transfers further filter segments onto the transfer drum 15.

[0073] The filter segment group assembly device 18 can, for example, be a Merlin of the patent holder, which is shown in EP 1 441 604 B1 and has, for example, the reference numeral 41 there.

[0074] According to the invention, one of the drums 11 to 15 or 11' to 15' or several of these drums, preferably at least four drums per filter run 34, 34', can be provided with a device according to the invention. The drums 15, 16, 15', 20, 21, 22, 30 and / or 32 can also be provided with a device according to the invention.

[0075] Following the assembly drum 15', a tumbling and cutting drum 20 is attached, in which the assembled filter segments are pushed together, for example by tumbling, and a cut can be made, for example, in the middle of a filter segment provided in the middle.

[0076] A reversing drum 21 then follows, which can be designed such that a movable element, rotating with the respective trough of the drum 21, removes a first portion of filter segments from the position of the trough in which a filter element was cut and places them back on the other side of the group of filter segments. For the function of this reversing drum 21, reference is made to EP 3 189 740 B1, which, moreover, refers to the embodiment of the Fig. 1 Full reference is made to the following. In this case, the reversing device 33 includes the reversing drum 21 with possibly further components acting in conjunction with the reversing drum 21.

[0077] The turning device 33 is followed by a covering device, which first provides a wobble drum 22, by means of which the groups of filter segments are pushed together and precisely adjusted in a transverse axial direction, in order to then be covered with a covering material 26.

[0078] The covering material 26 is glued by a gluing device 25, which can be, for example, nozzle gluing or disc or roller gluing. The gluing takes place on the side of the covering material strip indicated by the arrow at the gluing device 25. On a deflecting roller 23, the glued covering material strip 26 is deflected and cut into predefinable lengths of covering material strips by a cutting device 24. These strips are attached to the group of filter segments upon contact and pre-folded by the pre-folding star 27 to ensure high-quality wrapping of the group of filter segments on the roller drum 30. The roller drum 30 is supported by a roller block 31, as is known, to wrap the covering material strip around the group of filter segments.

[0079] A discharge drum 32 then follows, by means of which the completed multi-segment fields, encased in covering material 26, are discharged, for example, into a stack former. Further drums can be provided between the discharge drum 32 and the rolling drum 30, for example, test drums in which the tensile resistance can be measured. Laser perforation can also be provided.

[0080] Fig. 2Figure 40 schematically shows a three-dimensional representation of a device for transporting rod-shaped articles used in the tobacco processing industry. A drum 40 is mounted on a carrier, which is driven by a motor 43. The drum 40 is connected to the carrier at its end face 44 via screws 41. The drum body 60 is axially mounted onto the carrier or a concealed drive shaft and detachably connected to the drive shaft or carrier by means of the screws 41. The drum 40 has receiving recesses 42 for rod-shaped articles such as filter elements or filter segments.

[0081] Fig. 3 Figure 1 schematically shows a device according to the invention for transporting rod-shaped articles for the tobacco processing industry. Here, in comparison to the prior art, Fig. 2A handle 51 is provided, which serves to operate a clamping device 50 for the detachable connection of the drum body 60 to the support or the drive shaft, as shown. The handle 51 is in a second housing 63, as shown in Fig. 4 better illustrated, mounted. The second housing 63 is screwed to the end face of the drum body 60 with screws 52. The drum body 60 in Fig. 2 has through holes at this point, whereas the drum body 60 according to the Fig. 3 It has screw holes exactly at this point.

[0082] Fig. 4 Figure 1 schematically shows a sectional view of a section of the device according to the invention for transporting rod-shaped articles of the tobacco processing industry.

[0083] A support 61 is screwed into a drive shaft 56. The drive shaft 56 is supported by bearings 59. The support 61 comprises a housing 62 into which retaining elements 54 and 55, designed as balls, are inserted.

[0084] A handle 51, designed as a torque handle, is connected to a drive element 53. The drive element 53 is mounted in the second housing 63 via a thread. The drive element 53 can be moved to the left to tighten it or to the right to loosen it by turning the handle 51 in the direction of the arrow.

[0085] The first housing 62 contains two end stops 57 and 58, which prevent the retaining links 54 and 55, and especially retaining link 55, from moving too far out of the first housing 61. These are therefore end stops for the retaining links.

[0086] The handle 51 is attached to a second housing 63, which is connected to the front face 44 of a drum 40 or drum body 60.

[0087] The clamping device 50 functions as follows: To clamp the drum body 60 to the support 61, the drive element 53 is moved axially towards the support 61 or the drive shaft 56. This is done by turning the handle 51. This moves a retaining element 55, which is designed as a ball, axially to the left, which in turn moves a retaining element 54 radially outwards. Fig. 4 is pressed upwards. The retaining element 54 enters a recess 64, which in this embodiment is designed as a circumferential internal groove 64 of the second housing 63. For the sake of simplicity, in Fig. 4Only two balls are shown. Preferably, a further retaining element 54 is provided, which is arranged, for example, offset by approximately 90° or preferably by 180° to the retaining element 54 and can also be pressed into the groove 64. Alternatively, three retaining elements 54 can be provided, arranged at an angular interval of 120°.

[0088] Through this mechanism, the second housing 62 is clamped against the first housing 61, whereby the drive shaft 56 or the carrier 61 is positively or at least force-fit connected to the drum body 60.

[0089] Fig. 5Figure 1 schematically shows a three-dimensional representation of a device according to the invention, in particular a quick-release fastener according to the invention, in which, compared to the previous embodiment, a knurled nut 70 is added to prevent accidental loosening of the handle 51, which is designed as a torque handle. The knurled nut 70 locks the handle 51 in place, which is connected to the drive element 53.

[0090] Furthermore, an adjustable and rotatable ring 71, designed as a marking ring, is provided. The marking ring 71 has a marking 77 that can be aligned with the marking 76 on the knurled nut 70. The marking ring 71 visually indicates the closing position of the device according to the invention, particularly the knurled nut, by means of a scale mark or a marking 77 on the circumference. Several scale marks or markings can also be provided to represent different stages of closure.

[0091] To prevent loss when unscrewing or loosening the closure or the handle 51, the handle has a widening 78 on its stem which engages in a bore in the knurled nut 70 and is secured by a retaining ring 74 inserted in an inner groove of the bore in the knurled nut.

[0092] Fig. 6schematically shows the embodiment Fig. 5 in a schematic sectional view.

[0093] To enable higher surface pressures, a pressure bolt 75 is provided, which is made of a hardened material, in particular a hardened steel.

[0094] Fig. 7 shows the embodiment Fig. 5 omitting the knurled nut 70 in a schematic three-dimensional representation.

[0095] To enable safe and quick replacement of the conveying element, vent holes 72 are provided, particularly in the second housing 63. This prevents air from accumulating during the installation of the conveying element, especially the drum body.

[0096] The knurled nut 70 is secured by a bolt 73, which is operatively connected to the second housing 63. This also limits the maximum rotational range, ensuring that the marking 76 or multiple markings 76 on the knurled nut are unambiguous.

[0097] Figures 8 and 9 show a part of an embodiment of a clamping device of a device according to the invention in a schematic sectional view.

[0098] For the sake of simplicity and clarity, some elements have been omitted. It can be seen that a compression spring 80 presses against a retaining element 55. The compression spring 80 presses against the retaining element 55, which is centrally located, along a longitudinal axis or direction of movement of the drive element 53. The compression spring 80 ensures that the retaining element 55 is always connected to the drive element, which is located in Fig. 8not shown, is present, particularly when the drive element is triggered by movement from the closed position to the open position, i.e., to the right. In this case, the retaining element 54, which can move transversely axially – i.e., in the illustration of the Figure 8 vertically -, returning to the downward resting position. Fig. 8 This shows the case of the closed clamping device 50 and Fig. 9 the case of the open clamping device 50. It can be seen that the retaining elements are open depending on the position (see Fig. 9 ) or closed (see Fig. 8) their position. The compression spring 80 ensures a secure and distinct open or closed position. This is particularly advantageous if the clamping device has been over-greased or not completely cleaned. Otherwise, the retaining links 54 and 55 might not be able to move smoothly within their positions.
