Description

Technical Field

[0001] The invention relates to a control cam for controlling the position of clamping arms of a clamping device that are pivotable relative to one another, and to a clamping device for holding containers in a container handling device, for example for holding beverage containers in a neck section, in order to fill or close the beverage containers in a beverage filling plant. Background Art

[0002] Known is, in beverage filling facility, container to be filled or filled container is transported through each processing station of container treatment device by means of clamping device.At this, different clamping devices are known, and described clamping device keeps corresponding container to be processed in different ways and methods.

[0003] For example, passive clamping devices are known that are elastically preloaded and then held simply by inserting the corresponding container into the clamping device. DE 10 2015 218 204 A1 discloses such a clamp for holding containers. The clamp has a fixed position. To hold the container, it must be pressed into the clamp. The rigid clamping arms are deployed outward, requiring the container to be moved to overcome the closing force of the clamping arms caused by the deployment of the clamp. Consequently, the container is subjected to high forces during insertion, making such holding devices unsuitable for holding or retaining fragile and / or easily deformed containers, as well as thin-walled containers. There is at least a tendency to scratch the surface of the container, which reduces its quality.

[0004] Also known are active clamping devices, in which the opening and closing of the respective holding sections of the clamping device are actively performed by means of an actuator. Such active clamping devices are used, in particular, to enable the safe and gentle removal of the respective container from a preceding clamping device or to ensure an equally safe and gentle transfer of the container to a subsequent clamping device. In particular, by actively opening and closing the respective clamping device, increased friction on the respective container, which could, for example, cause scratches on the container, can be avoided, and on the other hand, a predetermined holding or clamping force can be set that can be maintained within a predetermined tolerance range for the container dimensions. Such active clamping devices are composed of a plurality of parts, such as a clamping arm, a bushing, a spring element, a preload element, and corresponding connecting elements for securely connecting the aforementioned components. Consequently, clamping devices constructed in this manner are difficult to clean and have a correspondingly high manufacturing cost.

[0005] EP 0 939 044 A1 discloses a bottle gripper having a gripping device with two gripping arms that can be brought into a holding position or a release position by means of a control cam. The control cam interacts with a bearing surface formed on each gripping arm, and the bearing surface is formed as part of a spring pad that is arranged on the respective gripping arm.

[0006] EP 2 143 674 A2 discloses an active clamping device for holding containers, in which two gripping arms or clamping arms are held in an open position by means of separate magnet arrangements. The clamping arms have rearwardly directed closing levers that interact with closing cams arranged between them to bring the clamping arms from the open position into the closed position.

[0007] DE 10 2005 014 838 A1 discloses an active clamping device for holding containers. The clamping device has two clamping arms that are movable relative to one another for opening and closing. To securely hold the container, one clamping arm of the clamp is dimensionally stable, while the other clamping arm is dimensionally resilient. The clamping arms are preloaded into the open position by means of magnets arranged thereon and pivoted into the closed position by means of a control cam.

[0008] Conventional, one-sidedly preloaded clamping devices have in common that the control cam has exactly one contact surface with each clamping arm, via which the control cam contacts the clamping arm. When the control cam is pivoted, the control cam slides over the contact surface with its contact surface. More specifically, when the clamping arm is opened and closed by pivoting the control cam, it has exactly one contact surface with the control cam. In this case, the force exerted by the control cam on the clamping arm is directed oppositely to the preload force applied by the preload mechanism. The force exerted on the clamping arm by the control cam always points in the same direction. For example, when preloading an active clamping device into the closed position, the control cam must exert a force on the clamping arm opposite to the preload force in order to open the clamping arm. To this end, the control cam is typically designed so that its contact surface has increasing radii or spacings in the circumferential direction relative to the control cam's pivot axis—in other words, it has a cam shape, as disclosed, for example, in DE 10 2005 014 838 A1. The control cam slides along the clamping arm via its contact surface. Due to the increased radius or spacing at the point of contact with the clamping arm, the clamping arm is pressed out of its preloaded position and thus pivots about its pivot axis. To close the clamping arm, the control cam is pivoted again so that it slides back past the clamping arm via its contact surface. Due to the reduced spacing in the area of ​​the contact surface between the control cam and the clamping arm, the clamping arm is pressed back again by the preload force.

[0009] In clamping devices with a unilaterally preloaded clamping arm, the clamping device can be moved into another position by operating a control cam against the preload force, and can be moved back to the preloaded position by releasing or resetting the control cam. The return movement caused by the preload force is subject to a certain amount of inertia. This can lead to sudden gripping and release of the container. Furthermore, such active clamping devices can cause high wear between the clamping arm and the control cam, particularly on their contact surfaces, since the latter must always work against the unilaterally directed preload force. Summary of the Invention

[0010] Based on the known prior art, the object of the present invention is to provide an improved clamping device for holding containers in a container handling device, preferably for holding beverage containers in a neck section.

[0011] This object is achieved by a control cam having the features of the invention for controlling the position of clamping arms that can be pivoted relative to one another in a clamping device, the clamping arms each having a retaining section. Advantageous developments are apparent from the description and the drawings.

[0012] Accordingly, a control cam is proposed for controlling the position of clamping arms of a clamping device that can be pivoted relative to each other, the control cam comprising: a shaft section for pivotally supporting the control cam around a control cam pivot axis in a hub section of a carrier plate of the clamping device; and at least one coupling element for coupling the control cam to the clamping arm of the clamping device, wherein the control cam is capable of pivoting around the control cam pivot axis between an open preset position and a closed preset position.

[0013] According to the present invention, the control cam is characterized in that at least one coupling element includes: a first coupling surface extending in the direction of the pivot axis of the control cam, constructed and established for transmitting a first switching force to the clamping arm; and a second coupling surface different from the first coupling surface, extending in the direction of the pivot axis of the control cam, constructed and established for transmitting a second switching force oriented opposite to the first switching force to the clamping arm.

[0014] Since at least one coupling element includes: a first coupling surface extending in the direction of the control cam pivot axis, the first coupling surface is constructed and established for transmitting a first switching force to the clamping arm; and a second coupling surface different from the first coupling surface and extending along the control cam pivot axis, the second coupling surface is constructed and established for transmitting a second switching force oriented opposite to the first switching force to the clamping arm, the coupling element can be used to permanently and positively guide the clamping arm during opening and closing, and preferably also provide a preload of the clamping arm in at least one predetermined position, preferably in the open position or closed position of the clamping arm or the retaining section of the clamping arm.

[0015] In other words, due to the coupling provided by the coupling element, the position and movement of the clamping arm are always predetermined by the position and movement of the control cam. Accordingly, the opening of the clamping arm for receiving the respective container to be processed, the closing of the clamping arm for holding the container, and the subsequent opening for ejecting the previously held container are each actively controlled and guided by the control cam.

[0016] Accordingly, it is possible to prevent the clamping arm and the control cam from temporarily becoming disengaged or losing contact with each other when a switching impulse occurs on the control cam, which causes a sudden movement of the control cam, as would happen with conventional clamping devices with conventional one-sided prestressing of the control cam, for example if the spring force of the one-sided prestressing is insufficient, so that they then collide with each other again. Consequently, the container to be held by the clamping device can be clamped and released relatively gently, without uncontrolled jerks occurring when the clamping arms are opened or closed.

[0017] Furthermore, a defined contact of the holding section against the container to be held can be achieved by the permanently present guidance provided by the coupling element and the clamping arm, the coupling element being correspondingly formed on the clamping arm.

[0018] Therefore, compared with conventional devices, a clamping device with a control cam designed in this way is subject to particularly low wear during operation, in particular in the area of ​​the coupling between the clamping arm and the control cam, which in turn has a positive effect on the service life of the control cam and the components of the clamping device.

[0019] With a container handling device having a clamping device with a control cam, maintenance intervals are increased due to the reduced wear compared to a container handling device having a conventional clamping device.

[0020] Furthermore, due to the always positively guided movement of the holding section, jerks during the opening and / or closing of the clamping arms are reduced or even avoided compared to conventional clamping devices, and control via the control cam reduces or even avoids damage to the container to be held and / or spillage of filling material, such as a beverage, located in the container, as well as the associated contamination of the clamping device, other areas of the container handling device and the outside of the container.

[0021] The term "pivot axis" is understood to mean a geometric axis representing a center of rotation and, in this context, particularly a fixed pivot axis, i.e., an axis that is fixed relative to the position of the clamping device. Therefore, a movement axis in the sense of a momentary center cannot be understood as a "pivot axis." A body that simultaneously moves rotationally and translationally within a plane does not pivot about a fixed axis and therefore does not have a pivot axis as defined herein.

[0022] Of course, the geometric pivot axis can be provided or formed in a manner known per se in the form of a mechanical axis or shaft. For example, a journal, pin, or bolt can be provided on a carrier plate of the clamping device, on which the clamping arm, for example, is pivotably mounted in the sense of a shaft-hub connection. In the present case, the control cam comprises, for example, a shaft section that is rotatably mounted in a hole in the carrier plate, thereby providing the geometric axis.

[0023] “Oppositely oriented” is understood here to mean that the first switching force and the second switching force each have a circumferential component relative to the control cam pivot axis, wherein the circumferential component of the first switching force and the circumferential component of the second switching force are oppositely oriented, ie, in opposite directions.

[0024] The clamping arms of the clamping device, which are pivotable relative to one another, preferably each have a holding section, wherein the holding sections interact, depending on the operating state of the clamping device, to receive, hold and remove the respective container to be processed.

[0025] According to another preferred embodiment, the coupling surface of at least one coupling element is arranged on the coupling element relative to the coupling element, in particular relative to its contour or cross-sectional contour perpendicular to the pivot axis of the control cam. According to another preferred embodiment, at least one coupling element is designed in the form of an elongated slot, preferably for accommodating a control pin provided on the clamping arm, or in the form of a control pin, preferably for entering an elongated slot provided on the clamping arm. In this way, continuous, i.e., permanently positive, guidance of at least one clamping arm of the clamping device can be provided in a particularly advantageous manner by the control cam.

[0026] An “elongated hole slot” is understood here to be a slot that essentially has the shape of an elongated hole, i.e., extends in the longitudinal extension from a first end to a second end and comprises between the two ends side walls that extend essentially parallel to one another, in other words, extend relative to one another transversely to the longitudinal extension at a fixed distance, said side walls preferably having a straight, i.e., infinite, radius of curvature.

[0027] The longitudinal extension of the elongated slot is related to a plane oriented perpendicular to the control cam pivot axis in this case. In other words, the elongated hole shape of the elongated slot can be recognized when viewed in the direction of the control cam pivot axis.

[0028] The elongated hole extends as a groove as a recess into the body having the above-mentioned elongated hole shape, specifically to a predetermined depth in the direction of the pivot axis of the control cam and / or at least partially through the entire body.

[0029] If the control cam comprises at least one control pin, then according to a further preferred embodiment, the at least one control pin extends in the direction of the pivot axis of the control cam at a predetermined height from the end face of the shaft section.

[0030] If the control cam comprises at least one elongated slot, then according to a further preferred embodiment, the at least one elongated slot extends in the direction of the pivot axis of the control cam to a predetermined depth from the end face of the shaft section into the control cam.

[0031] In order to enable particularly precise and synchronous control of the retaining section of the clamping arm of the clamping device, two coupling elements are provided according to another preferred embodiment, wherein each coupling element is designed to couple the control cam to one of the two clamping arms of the clamping device, wherein the first coupling element, preferably the first control bolt or the first elongated hole, preferably has a first distance from the pivot axis of the control cam; and the second coupling element, preferably the second control bolt or the second elongated hole, has a second distance from the pivot axis of the control cam, wherein the value of the second distance is preferably greater than the value of the first distance.

[0032] According to another preferred embodiment, at least one coupling element, preferably at least one control pin or at least one elongated slot, is arranged eccentrically with respect to the pivot axis of the control cam. Consequently, a lever arm is always provided by the coupling element relative to the pivot axis of the control cam, which, when the control cam is pivoted, always exerts a force on at least one clamping arm via its coupling to a corresponding coupling element on the clamping arm, thereby controlling the movement of the clamping arm and / or the holding force exerted on the container held in the clamping device by the holding section of the clamping arm.

[0033] According to a further preferred embodiment, at least one control bolt comprises a section, preferably an arc-shaped section, which is curved relative to a longitudinal center axis of the control bolt, which is preferably aligned parallel to the pivot axis of the control cam.

[0034] Alternatively or additionally, at least one control bolt can have a cam segment which extends in a plane which is oriented perpendicularly to the pivot axis of the control cam.

[0035] Preferably, at least one coupling surface is arranged in the curved section and / or the cam section.

[0036] If, according to a preferred embodiment, two control pins are provided, the control pins can be connected via a connecting wall, which can preferably be understood as two cam segments connected to one another, wherein each cam segment is assigned to a control pin.

[0037] According to a further preferred embodiment, the control cam comprises a radial securing groove for receiving a securing element, preferably a feather key or a securing plate, in order to axially secure the control cam relative to the control cam pivot axis.

[0038] Alternatively or additionally, at least one control bolt can have a fastening lug on its free end opposite the end of the shaft section, viewed in the direction of the pivot axis of the control cam, for axially fastening the control cam to the clamping device.

[0039] Preferably, the fixed connecting plate is designed in the form of a preferably circular flange arranged concentrically or eccentrically with respect to the longitudinal center axis of the control bolt, the outer diameter of which is preferably greater than the radius of the arc-shaped section of the control bolt and / or is preferably designed to be greater than the width of the elongated hole groove provided on the clamping arm of the clamping device transversely to its longitudinal extension.

[0040] According to another preferred embodiment, the control cam has an interaction portion extending radially outward with respect to the control cam pivot axis for interacting with an interaction pin of the container handling device, wherein the interaction portion is designed to limit the range of movement of the control cam about the control cam pivot axis, wherein the interaction portion is preferably designed to interact with a stop of the clamping device, wherein the control cam preferably has two arms extending radially outward with respect to the control cam pivot axis.

[0041] According to another preferred embodiment, the control cam includes a pretensioning element, which interacts with a stop element of the clamping device so that when the control cam is in the open preset position, the control cam is pretensioned into the open preset position, and when the control cam is in the closed preset position, it is pretensioned into the closed preset position.

[0042] It has proven to be advantageous if the prestressing element according to a further preferred embodiment is designed as an elastic prestressing element and / or a magnetic prestressing element.

[0043] According to another preferred embodiment, the prestressing element comprises an elastic spring element, wherein the spring element preferably has a curvature relative to the control cam pivot axis which is greater than the curvature of a geometric pitch circle located concentrically to the control cam pivot axis at the height of the spring element.

[0044] According to another preferred embodiment, the preload element includes a connecting plate extending radially outward to a geometric pitch circle concentric with the control cam pivot axis, and a spring element extending from the connecting plate transversely to the radial direction relative to the control cam pivot axis. Preferably, one spring element extends on each side of the connecting plate relative to the circumferential direction of the control cam pivot axis. At least one spring element is preferably configured such that a spacing exists between a free end of the spring element and an arm opposite the end of the spring element, thereby providing a positively locking receptacle for accommodating the pulley of the clamping device in the circumferential direction relative to the control cam pivot axis.

[0045] It has proven particularly expedient if, according to another preferred embodiment, at least one spring element is designed as a curved leaf spring, in the form of a pin mounted elastically radially relative to the control cam pivot axis, or in the form of a curved beam with a free end.

[0046] According to another preferred embodiment, the pre-tensioning element is constructed in the form of a magnetic pre-tensioning element, wherein the magnetic pre-tensioning element preferably includes at least one magnetic element arranged on the arm, wherein the magnetic pre-tensioning element preferably includes two magnetic elements, which are respectively arranged in the arms, wherein at least one magnetic element is constructed and arranged to interact with the magnet of the clamping device when the control cam is installed in the clamping device, so that a magnetic attraction exists between the magnet and the magnetic element at least when the control cam is in the closed preset position and / or the control cam is in the open preset position.

[0047] Further advantageous embodiments and further advantageous effects of the control cam can be found in the following description of the preferred exemplary embodiment.

[0048] The above-mentioned object is also achieved by a clamping device having the features of the invention for holding a container in a container handling device, preferably for holding a beverage container in a neck section. Advantageous developments can be seen from the description and the drawings.

[0049] Accordingly, a clamping device for holding a container in a container handling device is proposed, preferably for holding a beverage container in a neck section, comprising two clamping arms, each of which has a holding section for holding the container to be held. The clamping device is characterized in that the clamping arms are coupled to a control cam according to one of the above-described embodiments.

[0050] Since the clamping device comprises a control cam according to one of the above-described embodiments, the advantages and effects described above and below with regard to the control cam apply in an analogous manner to the clamping device. BRIEF DESCRIPTION OF THE DRAWINGS

[0079] Preferred embodiments are described below with reference to the accompanying drawings. Identical, similar or identically acting elements are provided with the same reference numerals in different figures, and a repeated description of the elements is partially omitted to avoid redundancy.

[0080] exist Figure 1 20 for controlling the position of the clamping arms 10 pivotable relative to one another in the clamping device 1, which can each have a holding section 11, (see also Figure 10 The control cam 20 includes a shaft section 26 for pivotally mounting the control cam 20 about a control cam pivot axis 21 in a hub section 5 (not shown here) of the carrier plate 2 of the clamping device 1. The control cam also includes two coupling elements for coupling the control cam 20 to the clamping arm 10 of the clamping device 1. In this case, the coupling elements are each designed in the form of a control pin 32, 32' that is arranged eccentrically with respect to the control cam pivot axis 21.

[0081] The control pins 32 , 32 ′ extend from the end face 27 of the shaft section 26 in the direction of the control cam pivot axis 21 . Accordingly, they each have a longitudinal center axis 325 , 325 ′, which is aligned parallel to the control cam pivot axis 21 .

[0082] The control pins 32, 32' are each designed and arranged to engage with the elongated slots 31 (see FIG. 1 ) provided on the corresponding clamping arm 10 to be controlled by the control pins 32, 32'. Figure 10 ) interact with or are coupled to the elongated slot. The coupling is designed such that the respective control pin 32, 32' is guided in the associated elongated slot 31 in such a way that the control pin is preferably movable translationally along the elongated slot 31 or along a longitudinal extension 310 of the elongated slot 31 extending perpendicularly to the control cam pivot axis 21, and preferably also rotationally movable relative to the elongated slot 31, preferably by rolling and / or sliding on a side wall 311 of the elongated slot 31.

[0083] Alternatively, the control cam 20 can also have a coupling element in the form of an elongated slot 31, as will be described below with respect to Figures 22 to 24 As explained in detail. Accordingly, the elongated slot 31 extends into the control cam from the end face 27 of the control cam 20 in the direction of the control cam pivot axis 21 with a predetermined depth. Furthermore, the elongated slot 31 is thus designed to receive a control pin 32 which is associated with the elongated slot 31 and is arranged on the clamping arm 10 to be controlled, thereby enabling the control pin 32 to be guided along the longitudinal extension 310 of the elongated slot 31, preferably in translation and rotation, as described above in relation to the control pin 32 according to the embodiment of the present invention. Figure 1 As described for the control pins 32, 32'.

[0084] In such a Figure 1 In the embodiment shown in FIG, the first control pin 32 has a radial spacing 320 from the control cam pivot axis 21 that is smaller by a predetermined amount than a radial spacing 320′ of the second control cam 32′ from the control cam pivot axis 21. In this case, the spacings 320, 320′ are relative to the central longitudinal axes 325, 325′.

[0085] Since the control pins 32, 32' are arranged at different radial distances 320, 320' from the control cam pivot axis 21, symmetrical pivoting of the two clamping arms 10 of the clamping device 1 with the control cam 20 is possible, even if the distances between the pivot axis 12 of the clamping arms 10 and the elongated slots 31, 31' are different with respect to the two clamping arms 10, 10'. The aforementioned distances 320, 320' are preferably selected such that the transmission ratio provided by the first pair consisting of the first elongated slot and the first control pin substantially corresponds to the transmission ratio provided by the second pair consisting of the second elongated slot and the second control pin.

[0086] The central longitudinal axis 325, 325' is the central axis of the cylindrical side wall of the respective control cam 32, 32'. The cylindrical side wall, synonymously the side surface, corresponds to the arc-shaped section 321 of the control cam 32, 32' extending along the entire circumference.

[0087] In the state mounted on the clamping device 1 , the control cam 20 can be pivoted about its control cam pivot axis 21 between an open preset position and a closed preset position.

[0088] In order to fix the control cam 20 axially in a fixed position relative to the control cam pivot axis 21 in the clamping device, the control cam 20 optionally includes a radial fixing groove 327 for accommodating a fixing element such as a sliding key or a fixing plate, which is preferably arranged on the carrier plate 2 of the clamping device 1.

[0089] In order to be able to change the position of the control cam 20 when it is mounted on the container conveying device of the container processing device, the control cam has an interaction portion 22 extending radially outward with respect to the control cam pivot axis 21. For example, an interaction pin provided at a fixed position of the container processing device strikes against the interaction portion, thereby causing the control cam 20 to pivot.

[0090] To limit the range of motion of the control cam 20 about the control cam pivot axis 21, the interaction portion 22 can be configured to interact with an optional stop, preferably provided on the carrier plate 2, of the clamping device. For this purpose, the control cam 20 preferably includes two arms 24 extending radially outward relative to the control cam pivot axis 21, viewed in the circumferential direction. These arms are preferably configured to abut against a stop provided between the arms 24 or against two stops provided radially outside each arm 24 in an end position. Thus, when installed in the clamping device 1, the control cam 20 can only pivot about the control cam pivot axis 21 at an angle 23, in this case 45°, limited by the arms 24, in particular by interaction with at least one stop 3. The end positions of the control cam 20, in which the control cam 20 rests with its arms 24 against the stop 3, represent the preset positions relative to the open and closed positions of the retaining section of the clamping arm 10 of the clamping device 1. Accordingly, one end position represents the open preset position, while the other represents the closed preset position.

[0091] The control cam 20 also includes a prestressing element, currently in the form of an elastic spring element 41, which is designed to interact with a stop element of the clamping device 1 so that the control cam 20 is prestressed into the open preset position when it is in the open preset position, and is prestressed into the closed preset position when the control cam 20 is in the closed preset position.

[0092] The control cam 20 is preferably integral or even single-piece. The control cam 20 is preferably made of metal, preferably a steel alloy. Alternatively, the control cam can also be made of, preferably, POM, and / or POM can be part of the control cam 20. The control pin 32, the elongated slot 31, and / or the shaft section 26 can preferably be provided with a coating, preferably a sliding coating and / or a wear-resistant coating. The control cam 20 is preferably made of a different material than the carrier plate 2 and / or the clamping arm 10, for example, a metal of varying hardness or a plastic.

[0093] The arm 24 and the control pins 32, 32' are designed such that the lever arm ratio between the control cam pivot axis 21 and the predetermined engagement point of the interaction element of the container handling device for switching the control cam 20, and the lever arm ratio between the control pins 32, 32' and the control cam pivot axis 21 is substantially between 5:1 and 3:1, preferably substantially 4:1. "Substantially" is understood to mean that the difference resulting from the different spacings 320, 320' lies within the rounding or tolerance of the lever arm ratio. In other words, the difference in spacings 320, 320' is so small that the resulting difference is negligible compared to the aforementioned lever arm ratio.

[0094] As referenced below Figure 26 and 27 As described in detail, in order to be able to achieve a permanent forced guidance of the clamping arm 10 provided by the coupling of the coupling element of the control cam 20 to the clamping arm 10 by the control cam 20, each of the coupling elements of the control cam 20, which are currently designed in the form of control pins 32, 32', respectively includes a first coupling surface 36 extending in the direction of the control cam pivot axis 21 and designed and arranged for transmitting a first switching force to the clamping arm 10, and a second coupling surface 36 different from the first coupling surface 36, extending in the direction of the control cam pivot axis 21 and designed and arranged for transmitting a second switching force oriented opposite to the first switching force to the clamping arm 10 (for details, see Figure 26 and 27 ).

[0095] Figure 2 A perspective side view of a control cam 20 according to another embodiment is schematically shown, which corresponds essentially to the embodiment in FIG. Figure 1 Only the control pins 32, 32' and the interaction part 22, ie the arm 24, have different orientations from one another.

[0096] Coupling elements, in Figure 1 and Figure 2 The orientation of the control pins 32, 32' with respect to the interaction part 22 or the arm 24 is preferably predetermined such that the control pins 32, 32' are oriented perpendicularly to the plane defined by the pivot axis of the clamping arm in the closed predetermined position (see also Figure 11 ), or oriented parallel to said plane (see also Figure 12 ).

[0097] exist Figure 3 A perspective side view of a control cam 20 according to another embodiment is schematically shown in FIG. Figure 1 The implementation form in accordance with Figure 1 The implementation scheme is different in that, according to Figure 3The control bolts 32, 32' in the embodiment of the invention are connected by a connecting wall 324, which can be understood as two mutually connected cam sections 322. Therefore, in addition to or as an alternative to the optimal stop 3 (see Figure 10 ) In addition, it is possible to provide a limit to the movement of the control cam 20 around the control cam pivot axis 21. Because the control bolts 32, 32' are connected via the connecting wall 324, and the Figure 1 Compared to the embodiment in FIG. 1 , the control bolt has a greater bending stiffness in the radial direction with respect to the control cam pivot axis 21 .

[0098] Figure 4 A schematic perspective side view of a control cam 20 according to another embodiment is shown, which corresponds essentially to Figure 2 The implementation form of .

[0099] In accordance with Figure 4 The clamping device 1, according to Figure 1 The embodiment of the invention is different in that the control bolts 32, 32' each have a cam section 322. Therefore, in addition to or as an alternative to the optimal stop 3 (see Figure 10 ), it is possible to provide a limitation on the movement of the control cam 20 around the control cam pivot axis 21.

[0100] Furthermore, the control pin 32, viewed in the direction of the control cam pivot axis 21, has a fixing web 323 at its free end on the end side opposite the end side 27, which is in the present case designed as a circular collar arranged concentrically with the longitudinal center axis 325 of the control pin 32, the outer diameter of which is greater than the radius of the arc-shaped section 321 and, moreover, greater than the width of the elongated slot 31 transversely to the longitudinal extension 310 (see also ). Figure 15 ). Thus, a form fit is provided between the clamping arm 10 and the control cam 20 in the direction of the control cam pivot axis 21, so that the control cam 20 is Figure 15 In the state shown in FIG, not mounted on a container conveyor, the container is held on the gripping arm 10 .

[0101] Accordingly, according to Figure 4 In the case of the control cam 20, the fixing groove 327 is not required (see Figure 1-3 ), so the fixing groove is omitted here.

[0102] Figure 5 Schematically shown in Figure 4 A top view of the control cam 20 in FIG. 1 is provided, from which the prestressing element is described in detail, wherein the prestressing element is as already described with reference to FIG. Figure 1As mentioned, according to this preferred embodiment, the spring element 41 is formed, in the present case, as a bent leaf spring, and extends between the arms 24 essentially in the circumferential direction with respect to the control cam pivot axis 21. Figure 5 As can be seen in the figure, the spring element 41 has a curvature on its radial outer side, represented by a curvature radius 410, which is greater than the curvature of the geometric pitch circle 45 concentrically located with the control cam pivot axis 21 at the height of the connection point of the spring element 41 with the arm 24 of the interaction part 22, represented by means of a radius 450.

[0103] In the following about Figure 16 and Figure 17 The interaction of the prestressing element with the stop 3 of the clamping device 1 is described in detail.

[0104] The reference numeral 25 designates the angle of extension of the interacting portion 22 or the arm 24 in the circumferential direction with respect to the control cam pivot axis 21 , which in the present case is 45°.

[0105] Figure 6 A perspective side view of a control cam 20 according to another embodiment is schematically shown, which corresponds essentially to the embodiment according to Figure 3 The embodiment of the invention, wherein the control bolt 32 also has Figure 4 The fixed connecting plate 323 is provided, and accordingly no radial fixing groove is provided.

[0106] Figure 7 A perspective side view of a control cam 20 according to another embodiment is schematically shown. Figure 8 The control cam 20 essentially corresponds to the Figure 2 The control cam in the embodiment of the present invention, wherein the control bolts 32, 32' each include a cam section 322 in addition to their arc-shaped sections 321. In addition, the control cam 20 has the same Figures 1 to 6 Prestressing elements of different embodiments.

[0107] Instead of a continuous leaf spring which is fixed at both ends to the arms 24 or incorporated into the arms, the control cam 20 according to this embodiment has a preload element which consists of a connecting plate 46 which extends radially outwards essentially centrally between the arms 24 up to the pitch circle 45, and a spring element 41 which, at the radially outer ends of the connecting plate 46, extends essentially in the circumferential direction or tangentially to the control cam pivot axis 21 on both sides of the connecting plate 46 in the form of a curved crossbeam with free ends, wherein the free ends each end at a predetermined distance from the respective arm 24.

[0108] The spring element 41 has a curvature which is smaller than the curvature of the pitch circle 45. In other words, the radius of curvature 410 of the spring element 41 relative to the control cam pivot axis 21 is larger than the radius 450 of the pitch circle 45 at the level of which the connecting plate 46 ends.

[0109] Accordingly, the free end 411 is located radially further outwards relative to the control cam pivot axis 21 than the pitch circle 45 .

[0110] Due to the spacing between the free ends 411 on each side of the connecting plate 46 and the corresponding arm 24, a receptacle 49 is formed for receiving the pulley 42 of the clamping device 1 in the corresponding end position in a form-fitting manner, as viewed in the circumferential direction with respect to the control cam pivot axis 21 (see also Figure 18 ).

[0111] The spring element 41 is designed here so that it is elastically bent by a predetermined amount by the pulley 42 located in the receptacle 49. The spring element thus provides a prestressing force on the pulley 42, which prestresses the pulley 42 and thus the control cam 20 into the corresponding end position.

[0112] exist Figure 9 In the figure a further embodiment of the control cam 20 is schematically shown, which corresponds essentially to the embodiment of the control cam 20 in FIG. Figure 7 and 8 A control cam in which the preload element is designed as a magnetic preload element.

[0113] The magnetic preload element comprises two magnet elements 51 , which are arranged in each of the arms 24 .

[0114] The magnetic element 51 is designed and arranged so that it aligns with the magnet 50 of the stop 3 of the clamping device 1 (see also Figure 21 ) interact so that when the control cam 20 is in one of the end positions, there is a magnetic attraction force between the magnet 50 and the corresponding magnetic element 51.

[0115] Instead of the magnetic element 51, a magnetizable or ferromagnetic body can also be arranged in the arm 24, or the arm 24 itself can have a magnetizable or ferromagnetic material. It is also possible to replace the magnet 50 by a magnetizable or ferromagnetic material as long as a magnetic field-generating magnetic element 51 is present in the arm 24.

[0116] Furthermore, a connecting beam 28, preferably in the form of a circular ring segment, extends between the arms 24. Like the arms 24, the connecting beam can be designed to interact with the magnet 50 of the stop 3, so that a magnetic attraction force exists between the connecting beam 28, at least one magnetizable or ferromagnetic body or magnetic element (not shown) arranged in the connecting beam 28, and the stop 3. Thus, the control cam 20 can be held in a fixed position axially relative to the control cam pivot axis 21 in the clamping device 1 without the need for form-fitting elements, such as a fixing groove 327 or a fixing web 323.

[0117] exist Figure 10 Schematically depicts a perspective side view of a clamping device 1 for holding beverage containers in the neck section. The clamping device comprises two clamping arms 10, 10', each having a holding section 11 for holding the container to be held. The holding section 11 is designed, for example, to clamp the container to be held below its neck ring. For opening and closing, the clamping arms 10, 10' are each pivotably mounted on the carrier plate 2 about a pivot axis 12. The pivot axes 12 are oriented parallel to one another.

[0118] The clamping device 1 also includes a Figure 1 The control cam 20 is pivotable about a control cam pivot axis 21 oriented parallel to the pivot axis 12. To preset the position of the retaining segments 11 of the clamping arms 10, 10', the clamping arms 10, 10' and the control cam 20 are coupled, in this case via a coupling mechanism 30, described in detail below. Due to the coupling, pivoting the control cam 20 about its control cam pivot axis 21 causes the clamping arm 10 to pivot about its pivot axis 12, allowing the retaining segments 11 to move toward or away from each other in order to open and close the clamping device 1. In other words, the movement of the retaining segments 11 relative to each other is controlled via the control cam 20.

[0119] The coupling mechanism 30 is composed of or currently includes two pairs of coupling elements, each of which is composed of an elongated hole slot 31, 31' and a control bolt 32, 32' guided in the elongated hole slot 31; 31', wherein each pair of elongated hole slots 31, 31' and control bolts 32, 32' couples each clamping arm 10, 10' to the control cam 20.

[0120] Currently, such a coupling is provided as follows: each clamping arm 10, 10' has a coupling element in the form of an elongated slot 31, 31', in which a control pin 32, 32' associated with the elongated slot 31, 31' and arranged on the control cam 20 is guided, and the control pin is a coupling element of the control cam 20 that is designed corresponding to the coupling element of the clamping arm 10, 10'.

[0121] The "guidance" of the control bolts 32, 32' in the associated elongated slots 31, 31' is configured here so that the control bolts 32, 32' can move translationally relative to the elongated slots 31, 31' in a plane extending parallel to the control cam pivot axis 21, and can roll on and / or slide along the side walls of the elongated slots 31, 31', and can therefore move rotationally relative to the elongated slots 31, 31'.

[0122] The elongated slots 31, 31' extend completely through the clamping arms 10, 10' in each case in the direction of the control cam pivot axis 21. The elongated slots can therefore be understood to be through-holes in the form of elongated holes.

[0123] The elongated slots 31, 31' each have essentially the shape of an elongated hole, viewed in the direction of the control cam pivot axis 21. Accordingly, they extend in a longitudinal extension 310 oriented perpendicularly to the control cam pivot axis 21 from a first end 312 to a second end 312, with the side walls 311 running essentially parallel to one another between the two ends 312.

[0124] Currently, the elongated slots 31, 31' are each configured to be open on one side. In other words, one of the two ends 312 is configured as an open end. Currently, the open end 312 of each elongated slot 31, 31' is the end 312 closer to the control cam pivot axis 21.

[0125] In order to be able to change the position of the control cam 20 on a container conveying device mounted on a container handling device, the control cam has an interaction portion 22 extending radially outwards with respect to a control cam pivot axis 21, against which an interaction pin, for example, provided at a fixed position of the container handling device, can strike, thereby causing the control cam 20 to pivot.

[0126] To limit the range of movement of the control cam 20 about the control cam pivot axis 21, the clamping device 1 further includes an optional stop 3 provided on the carrier plate 2. The stop is arranged, as viewed in the circumferential direction relative to the control cam pivot axis 21, between two radially outwardly extending arms 24 of the control cam 20. Consequently, the control cam 20 can only pivot about the control cam pivot axis 21 at an angle 23 of 45°, limited by the arms 24. The end positions of the control cam 20, in which its arms 24 abut against the stop 3, are, in this case, predetermined positions relative to the open and closed positions of the retaining section 11. One end position is the predetermined open position, while the other is the predetermined closed position.

[0127] The holding section 11 can be moved accordingly by pivoting the control cam 20 in a preset position by closing the preset position. Figure 1and moves between a closed position shown in FIG and an open position preset by an open preset position.

[0128] The clamping device 1 further comprises a prestressing device 40 for holding or prestressing the control cam 21 in a preset position, ie in a closed preset position or an open preset position, as will be explained in more detail below.

[0129] The arm 24 and the control pins 32, 32' are designed such that the lever arm ratio between the control cam pivot axis 21 and the predetermined engagement point of the interaction element of the container handling device for switching the control cam 20 and the lever arm ratio between the control pins 32, 32' and the control cam pivot axis 21 is substantially between 5:1 and 3:1, preferably substantially 4:1. "Substantially" is understood to mean that the difference resulting from the different spacings 320, 320' lies within the rounding or tolerance of the lever arm ratio. In other words, the difference in spacings 320, 320' is so small that the resulting difference is negligible compared to the aforementioned lever arm ratio.

[0130] A sliding plate 4 is provided between the carrier plate 2 and the clamping arm 10 , which provides a sliding support for the clamping arm 10 relative to the carrier plate 2 .

[0131] Furthermore, a sliding plate 4 is also provided above the gripping arm 10 , which is intended to provide a sliding support of the gripping arm 10 relative to the container conveying device and on which the gripping device 1 can be mounted.

[0132] The clamping arm 10 and / or the carrier plate 2 can be made of metal, preferably a steel alloy. Preferably, the sliding plate 4 is made of a different material than the carrier plate 2 and / or the clamping arm 10, for example plastic, a copper alloy or a brass alloy.

[0133] Figure 11 A top view of a clamping device 1 in another embodiment is shown schematically. Figure 11 The clamping device 1 shown in FIG. 1 still substantially corresponds to the clamping device 1 in FIG. Figure 10 Clamping device in.

[0134] exist Figure 10 and Figure 11 The embodiments described in the preceding text have in particular in common that the clamping arms 10, 10' are asymmetrically designed, more precisely, with respect to the areas surrounding the elongated slots 31, 31'. This allows for a particularly compact design of the clamping device 1. In this regard, the elongated slot 31 provided on the clamping arm 10 has a first distance from the pivot axis 12 of the clamping arm 10, while the elongated slot 31' provided on the clamping arm 10' has a second distance from the pivot axis 12' of the clamping arm 10', the second distance being greater than the first distance. The distances correspond to the length of the lever arm.

[0135] In order that the two clamping arms 10, 10' can pivot about their respective pivot axes 12, 12' at the same angle when the control cam 20 is pivoted, in other words, can pivot symmetrically relative to one another, the control pin 32 guided in the elongated slot 10 is arranged on the control cam 20 at a first distance 320 from the control cam pivot axis 21, which is smaller than the distance of the second control pin 32' guided in the elongated slot 31' from the control cam pivot axis 21. This distance is selected so that the transmission ratio provided by the pair formed by the elongated slot 31 and the control pin 32 essentially corresponds to the transmission ratio provided by the pair formed by the elongated slot 31' and the control pin 32'.

[0136] In respectively Figure 10 and 11 In the closed position of the holding section 11 shown in FIG, the control cam 20 is in the closed preset position. The control pins 32, 32' are arranged on the control cam 20 so that in the closed preset position of the control cam 20, viewed in the direction of the control cam pivot axis 21, they lie on a line that is oriented perpendicular to a plane 35 formed by the two pivot axes 12, 12'.

[0137] According to Figure 10 The implementation plans are different. Figure 11 The control bolt 32' in the embodiment of the invention is connected by a connecting wall 324, which can be understood as two mutually connected cam sections 322. Therefore, on the one hand, in addition to or as an alternative to the optimal stop 3 (see Figure 1 ) In addition, it is possible to provide a limit to the movement of the control cam 20 around the control cam pivot axis 21. Because the control bolts 32, 32' are connected via the connecting wall 324, and the Figure 1 Compared to the embodiment in FIG. 1 , the control pin has an increased bending stiffness in the radial direction relative to the control cam pivot axis 21 .

[0138] Figure 12 Schematically shown Figure 11 A top view of the clamping device 1 in the open position, wherein the holding section 11 is in its open position. Accordingly, the control cam 20 is at a preset angle 23, currently 45°, relative to its Figure 11 The coupling provided by the control cam 20 and the clamping arms 10, 10' by means of the above-mentioned coupling mechanism 30 can also be understood as a forced guidance of the coupling arms 10, 10' by the control cam 20, and the coupling arms 10, 10' are also pivoted about their pivot axes 12, 12' respectively.

[0139] When the control cam 20 pivots between the open and closed preset positions, the control pins 32, 32' move along the elongated slots 31, 31' associated therewith. This movement of the control pins 32, 32', viewed relative to the elongated slots 31, 31', comprises a translational movement component along the longitudinal extension 310 of the elongated slots 31, 31' and a rotational movement component, and therefore comprises a sliding movement relative to the side walls 311 of the elongated slots 31, 31'.

[0140] In order to enable the last-mentioned rotational movement component, the control pins 32, 32' comprise a curved section about their respective longitudinal axis 325, in the present case in the form of an arc-shaped section 321. Figure 1 In the embodiment of the invention, the arc-shaped section 321 extends over the entire circumference of the cylindrical control pin 32, 32'. Figure 2 and 3 In the embodiment of , the arc-shaped sections 321 are each limited by a connecting wall 324 .

[0141] exist Figure 13 and 14 Schematically shown in the closed position ( Figure 13 ) and in the open position ( Figure 14 ) is a top view of a clamping device 1 according to another embodiment. The clamping device 1 basically corresponds to Figure 10 The clamping device 1 in.

[0142] With Figure 10 as well as Figure 11 and 12 The clamping device 1 is different, according to Figure 13 and 14 The clamping device 1 is designed such that in the closed position of the clamping device 1, i.e., when the holding section 11 is in its closed position and, accordingly, the control cam 20 is in the closed preset position, the control pins 32, 32', viewed perpendicularly to the control cam pivot axis 21, lie on a line 34 that is substantially parallel to a plane 35 formed by the pivot axes 12, 12'. In this embodiment, it is particularly effective to prevent the holding section 11 from being opened by pivoting the clamping arms 10, 10' about their pivot axes 12, 12' due to pressure on the holding section 11, for example, due to a sudden impact on a container held in the clamping device 1.

[0143] Figure 15 A schematic perspective side view of a clamping device 1 according to another embodiment is shown, which essentially corresponds to the embodiment of the present invention. Figure 10 The clamping device in.

[0144] According to Figure 10The implementation plans are different, depending on Figure 15 The clamping device 1 has a Figure 4 control pin.

[0145] As described above, the fixing web 323 is designed as a circular collar arranged concentrically with the longitudinal center axis 325 of the control pin 32, the outer diameter of which is greater than the width of the elongated slot 31 transversely to its longitudinal extension 310. Thus, a positive fit is provided between the clamping arm 10 and the control cam 20 in the direction of the control cam pivot axis 21, so that Figure 15 In the state shown in FIG. 1 , not mounted on a container conveyor, the control cam 20 remains on the clamping arm 10 .

[0146] Reference Figure 16 and 17 , discuss in detail the Figures 10 to 15 The clamping devices 1 shown have a common pre-tensioning device 40 .

[0147] Here, Figure 16 Schematically shown Figure 10 The bottom view of the clamping device 1 is shown in FIG. Figure 17 Schematically shown Figure 10 A perspective side view of a partial area of ​​the clamping device 1 from below.

[0148] The prestressing device 40 is designed to hold the control cam 20 in a predetermined end position, ie, the open predetermined position or the closed predetermined position, or to prestress it into said position.

[0149] In accordance with Figures 10 to 17 In the embodiment common to the clamping device 1 of , the prestressing device 40 is provided by a prestressing element arranged on the control cam 20, which, according to this preferred embodiment, is designed in the form of a spring element 41, in the present case as a bent leaf spring, and extends between the arms 24 in a substantially circumferential direction with respect to the control cam pivot axis 21. Figure 16 As can be seen, the spring element 41 has a curvature on its side facing the pulley 42, represented by the curvature radius 410, which is greater than the curvature of the geometric pitch circle 45 that is concentric with the control cam pivot axis 21 at the height of the connection point of the spring element 41 with the arm 24 of the interaction part 22, represented by the radius 450.

[0150] As especially from Figure 17 It can be seen that the stop 3 is formed by a pulley 42 rotatably supported on the carrier plate 2 via a bearing pin 48 , which pulley is in contact with a spring element 41 or rolls on it, by which the arm 24 providing the end position is limited.

[0151] Since the spring element 41 is curved radially outward relative to the pitch diameter 45 with respect to the control cam pivot axis 21 due to a smaller radius of curvature 410 than the radius 450, the spring element 41 exerts a spring force on the pulley 42, which is greatest at the center of the spring element 41, thereby prestressing the pulley 42 into the respective end position. Due to this prestressing force, the control cam 20 and the corresponding clamping arm 10 are in a stable state, i.e., either in the open position or in the closed position.

[0152] In order to move the clamping arm 10 out of the corresponding position, the control cam 20 must move against the tension provided by the spring element 41. In other words, when the pulley 42 rolls on the spring element 41, the force generated by the elastic force of the spring element 41 due to the elastic bending thereof must be overcome in order to enable relative movement of the pulley 42 and the control cam 20. Once the apex, i.e., the center of the spring element 41, is passed, the control cam 20 is assisted in moving to the corresponding end position by the elastic force provided by the spring element 41 due to its bending.

[0153] The stop 3 in the form of a pulley 42 supported on the carrier plate 2 is therefore understood to be a stop element, which is designed to interact with the prestressing element of the control cam 20, which is currently provided as a spring element 41, so that when the control cam 20 is in the open preset position, the control cam 20 is prestressed into the open preset position, and when the control cam 20 is in the closed preset position, it is prestressed into the closed preset position.

[0154] The reference number 25 designates the angle of extension of the interacting portion 22 or the arm 24 in the circumferential direction relative to the control cam pivot axis 21 , which in the present case is 45°.

[0155] As in Figure 17 It can be seen that the pulley 42 is eccentrically supported on a bearing pin 48 which is fixed in a rotationally fixed manner on the support plate 2. Accordingly, the rotation axis 43 of the pulley 42 is at a predetermined distance from the bearing center axis 44 of the bearing pin 48.

[0156] By rotating the orientation of the bearing pin 48 about its bearing center axis 44, the preload force provided by the spring element 41 can be varied. Accordingly, the holding force of the clamping arm in the corresponding end position, here the closed position, i.e., when the control cam 20 is in the closed preset position, can also be adjusted.

[0157] In an alternative embodiment, the support bolt 48 can be prestressed in the circumferential direction about the support center axis 44 so that the support roller 42 is pressed onto the control cam 20 in the radial direction about the control cam pivot axis 21, preferably in such a way that a torsion spring (not shown here) is provided between the support plate 2 and the support bolt 48.

[0158] If a spring element 41 is additionally provided in this embodiment, the preload which holds the control cam 20 in one of the end positions is formed by the spring force on the support roller 42 and the spring force on the spring element 41 .

[0159] Alternatively, in the case of such an elastic support of the pulley 42, which is rotatably supported eccentrically with respect to the support center axis 44, a rigid element can be provided instead of the elastic spring element 41, which, like the spring element 41, has a curvature that is greater than the curvature of the pitch circle 45. The prestressing force for holding the control cam 20 in one of the end positions is then provided solely by the spring element (not shown) on the side of the pulley 42.

[0160] The shape of the arm 24 and the orientation of the pulley 42 are designed so that the lever arm ratio between the control cam pivot axis 21 and the contact area of ​​the pulley 42 on the arm 24 and the lever arm ratio between the control pins 32, 32' and the control cam pivot axis 21 are substantially between 6:1 and 2:1, and preferably substantially 5:1, 4:1, or 3:1. "Substantially" is understood to mean that the difference resulting from the different spacings 320, 320' lies within the rounding or tolerance of the lever arm ratios. In other words, the difference in spacings 320, 320' is so small that the resulting difference is negligible compared to the aforementioned lever arms.

[0161] exist Figure 18 A bottom view of a clamping device 1 according to another embodiment is shown schematically in FIG. The clamping device 1 essentially corresponds to the one in FIG. Figure 17 Instead of a continuous leaf spring fixed at both ends to the arm 24 or transitioning into the arm, according to this embodiment, the clamping device in the embodiment according to Figure 7 and 8 The control cam 20 corresponding to the embodiment has a preload element in the form of a connecting plate 46 extending radially outwards essentially centrally between the arms 24 to the pitch circle 45, and a spring element 41, which extends on both sides at the radially outer ends of the connecting plate 46 essentially in the circumferential direction or tangentially to the control cam pivot axis 21, and is in the form of a curved beam with free ends, wherein the free ends each end at a predetermined distance from the corresponding arm 24.

[0162] As mentioned above, the curvature of the spring element 41 is smaller than the curvature of the pitch circle 45. In other words, the radius of curvature 410 of the spring element 41 with respect to the control cam pivot axis 21 is larger than the radius 450 of the pitch circle 45 at the level of which the connecting plate 46 ends.

[0163] Accordingly, the free end 411 is radially further outward relative to the control cam pivot axis 21 than the pitch circle 45. The pulley 42 forming the stop element is mounted so that it would roll on the pitch circle 45 if the web 46 were theoretically missing.

[0164] Since there is a distance between the free ends 411 on both sides of the connecting plate 46 and the corresponding arms 24, a receptacle 49 is formed for receiving the pulley 42 in the corresponding end position in a form-fitting manner when viewed in the circumferential direction about the control cam pivot axis 21.

[0165] The spring element 41 is designed in this case so that it is elastically bent by a predetermined amount by the pulley 42 located in the receptacle 49. The spring element thus provides a prestressing force on the pulley 42, which prestresses the pulley 42 into the corresponding end position.

[0166] In order to move the pulley 42 out of the respective end position, the control cam 20 must be pivoted counter to the preload provided by the spring element 41. This embodiment provides a particularly secure hold of the pulley 42 or the control cam 20 in one of the end positions, since the preload provided by the spring element 41 on the pulley 42 is greatest in the end positions.

[0167] The pulley 42 can optionally be similar to Figure 17 The embodiment in FIG is supported eccentrically to the bearing center axis 44 and / or is prestressed relative to the control cam.

[0168] exist Figure 19 A bottom view of a clamping device 1 according to another embodiment is shown schematically in FIG. The clamping device 1 essentially corresponds to Figure 17 The clamping device in FIG. 1 is different from the design of the prestressing device 40. Instead of the spring element 41 being provided as a continuous leaf spring, a pin 47 providing the prestressing element is elastically supported on the control cam 20 at a radial distance from the control cam pivot axis 21. Figure 17 In the embodiment of FIG, the bolt 47 has a curvature represented by a radius of curvature 410, which is greater than the curvature of the pitch circle 45. Due to its elastic support, the bolt 47 is prestressed radially outward against the pulley 42. Accordingly, the pulley 42 is held in one of the end positions by the bolt 47.

[0169] The pulley 42 used as a stop element can optionally be similar to Figure 17 The embodiment in FIG is supported eccentrically to the bearing center axis 44 and / or is prestressed relative to the control cam.

[0170] Figure 20A schematic perspective side view of a clamping device 1 according to another embodiment is shown, which essentially corresponds to the embodiment of the present invention. Figure 18 The implementation form of .

[0171] In this embodiment, the control pin 32 is similar to the Figure 10 The embodiment in is configured as a cylindrical pin extending parallel to the control cam pivot axis 21. On its end face, the cylindrical pin is connected above the clamping arm 10 via a fixed connecting plate 323, which extends between two control bolts 32.

[0172] The fixed connecting plate 323 corresponds in its function to the Figure 15 Additionally, with Figure 10 Compared to the embodiment in FIG. 1 , it provides an increased flexural rigidity of the control pin 32 in the radial direction relative to the control cam pivot axis 21 .

[0173] Figure 21 A schematic perspective side view of a clamping device 1 according to another embodiment is shown, which essentially corresponds to the embodiment of the present invention. Figure 10 Clamping device in.

[0174] According to Figure 10 The control bolt 32 according to this embodiment has a cam section 322, as already described. Figure 15 As described in the control pin 32' in FIG.

[0175] Furthermore, the pre-tensioning device 40 is designed as a magnetic pre-tensioning device 40. For this purpose, the stop 3 serving as a stop element has a magnet 50 which is connected to the stop 3 in a manner similar to that described in FIG. Figure 9 The control cam 20 is configured such that the magnetic elements 51 disposed in each arm 24 interact with each other such that, when the control cam 20 is in one of its end positions, a magnetic attraction force exists between the magnet 50 and the corresponding magnetic element 51. This magnetic attraction force holds the control cam 20 in the corresponding end position. To move the control cam 20 out of the corresponding end position, the magnetic attraction force must be overcome. Therefore, the magnetic elements 51 disposed in the arms 24 constitute a prestressing element for the control cam. This prestressing element is configured to interact with the stop 3 serving as a stop element, or more precisely, with its magnet 50, such that, when the control cam 20 is in the open preset position, the control cam 20 is prestressed in the open preset position, and when the control cam 20 is in the closed preset position, it is prestressed in the closed preset position.

[0176] Instead of the magnetic element 51 , a ferromagnetic body can also be provided in the arm 24 . Furthermore, it is possible to replace the magnet 50 by a ferromagnetic material, provided that a magnetic field-generating magnetic element 51 is present in the arm 24 .

[0177] Figure 22 A schematic top view of a clamping device 1 according to another embodiment is shown, which essentially corresponds to the embodiment of the clamping device 1 in FIG. Figure 10 The clamping device, wherein the pre-tightening device 40 is based on Figure 21 Magnetic preload device.

[0178] The coupling mechanism 30 is also different in that the control pin 32 is arranged on the side of the clamping arm 10. Figure 22 The side to be viewed as the lower side of the clamping arm 10 extends parallel to the control cam pivot axis 21 by a predetermined length toward the control cam 20 , wherein the side to be viewed is the side of the clamping arm 10 pointing in the direction of the control cam 20 .

[0179] Each control pin 32 is on the end side 27 pointing in the direction of the clamping arm 10. Figure 22 The control cam 20 is guided in a blind hole-like elongated slot 31 provided on the upper side of the control cam 20 and serving as a coupling element for the control cam 20 .

[0180] The control pin 32 is arranged on each of its clamping arms 10 at a distance or at a radius 326 from the pivot axis 12 of the respective clamping arm 10 . In other words, the control pin pivots about the respective pivot axis 12 on the radius 326 .

[0181] Figure 23 and 24 Schematically showing a method similar to that according to Figure 22 , a top view and a side view of the upper portion of the control cam 20 of an embodiment of the present invention, wherein the elongated slot 31 is designed to be open on one side. In other words, the end 312' facing radially outward with respect to the control cam pivot axis 21 is designed as a free or open end 312'. Thus, for example, cleaning fluid that enters the elongated slot 31 during cleaning of a container handling device having the clamping device 1 can flow out of the elongated slot 31 again at the open end 312'.

[0182] exist Figure 24 The elongated hole 31 can be seen as a blind hole configuration. The elongated hole 31 extends from the end face 27 to a predetermined depth into the control cam 20 parallel to the control cam pivot axis 21 .

[0183] Figure 25 A clamping device 1 according to another embodiment is schematically shown. The clamping device 1 corresponds essentially to the Figure 10 The clamping device is the same as in the , but with the following differences:

[0184] The coupling mechanism 30 comprises exactly one pair of an elongated slot 31 and a control pin 32. Here, the pair of the elongated slot 31 and the control pin 32 couples one of the clamping arms 10 directly to the control cam 20. This clamping arm 10 is also rotationally coupled to the other clamping arm 10' via a transmission 60.

[0185] In other words, the coupling mechanism 30 according to this embodiment includes exactly one pair of elongated slots 31 and control bolts 32 for moving the first clamping arm 10 via the movement of the control cam 20, and the coupling mechanism 30 also includes a rotational coupling unit, currently in the form of a transmission 60, for coupling the first clamping arm 10 with the second clamping arm 10', so as to thereby provide an indirect coupling of the second clamping arm 10' to the control bolt 20 via the clamping arm 10.

[0186] Accordingly, the control cam 20 has exactly one coupling element, here in the form of a control pin 32. Alternatively, the control cam 20 can also have a coupling element similar to Figures 22 to 24 There is precisely one elongated slot in which, as described above, a control pin 32 arranged on one of the clamping arms 10 is then accommodated in order to provide a coupling between the control cam 20 and one of the clamping arms 10 .

[0187] The two clamping arms 10, 10' each have a gear-like toothing section 61, which is arranged essentially concentrically with the pivot axis 12 of the respective clamping arm 10, 10' and extends perpendicularly thereto. The toothing sections 61 engage with one another, thereby forming a rotational coupling between the clamping arms 10, 10'.

[0188] The control pin 32 also includes a Figure 15 The fixed connecting plate 323 in the embodiment of the present invention.

[0189] Figure 26 Schematically shown in Figure 13 1 , a top view of a detail of the control cam 20 of the clamping device 1 in the direction of the control cam pivot axis 21, wherein for the sake of clarity only one of the two control pins 32 is shown. The following description of the control pin 32 also applies to the other control pin 32 ′, which is not shown here for the sake of clarity.

[0190] exist Figure 26 In, as in Figure 13As can be seen in the figure, the control cam is positioned in the closed preset position. Accordingly, the control cam preloads the clamping arms 10, 10' into the closed position. To this end, the control bolt 32 transmits a force 37' provided by the preload device 40 to the clamping arm 10 at its contact point with the side wall 311' of the elongated slot 31 of the clamping arm 10, which is indicated here by a dashed line. This force 37' can be understood as a closing force 37' because it presses the clamping arm 10 into the closed position or holds it in the closed position. The aforementioned contact point of the closing bolt 20 can be understood as a first coupling surface boundary point 37'.

[0191] If a switching process is started, in which the control cam 20 is moved from its Figure 26 The closed preset position shown in FIG is pivoted at an angle 23 to Figure 27 , the control cam 20 is then pivoted in the pivoting direction 13 as the switching process begins. This means that when the control cam 20 is still essentially in the closed preset position—excluding the play between the elongated slot 31 and the control pin 32—the (second) side wall 311 of the elongated slot 31, which is opposite the (first) side wall 311′ of the elongated slot 31, contacts the control cam and forms a contact point similar to the above-described contact point with the (second) side wall 311. This initial contact point with the side wall 311 can be understood as the first coupling surface boundary point 37 of the control pin 21. The control cam now applies the switching force 16, here correspondingly an opening force, to the clamping arm 10, which causes the clamping arm 10 to pivot out of the closed position.

[0192] The term "coupling surface boundary point" is not limited to a point in the geometric sense, but includes contact types generally known to those skilled in the art consisting of point contact, line contact and surface contact. Figure 7 As shown in FIG, the side walls of the cam segment 322 of the control cam 32 each form a coupling surface boundary point in the sense of surface contact.

[0193] exist Figure 27 It is schematically shown in Figure 26 Another top view of a detail of the control pin 21 in FIG. 20 perpendicular to the control cam pivot axis 21, wherein the control cam 20 is viewed from the Figure 26 The closed preset position shown in FIG is pivoted to the open preset position at an angle 23 and is accordingly present in the open preset position (see FIG. Figure 14 ). The closed preset position is denoted by reference numeral 15, and the open preset position is denoted by reference numeral 14. During the movement from the closed preset position to the open preset position, the control cam 32 slides with its arc-shaped section 321 from the first coupling surface boundary point 37 on the side wall 311 of the elongated slot 31 of the clamping arm 10 to be controlled to the second coupling surface boundary point 38.

[0194] Therefore, the control bolt 32 includes a first coupling surface 36 extending between a first coupling surface boundary point 37 and a second coupling surface boundary point 38, which is designed and established to transmit the first switching force 16, here as an opening force, to the elongated hole 31, more precisely to its side wall 311, which can be correspondingly understood as a coupling surface 39 of the elongated hole 31 for coupling with the coupling surface 36, and - if the control bolt 20 is preloaded into the open preset position - to transmit the preload force 16 for preloading the clamping arm 10 into the open position to the clamping arm 10.

[0195] Reference numeral 23 ′ denotes the pivoting of the control cam 20 from the open preset position 14 (backward) into the closed preset position 15. Similarly to the above, upon initiation of the pivoting process, the control cam 32 contacts the side wall 311 ′ via the second coupling surface boundary point 38 ′, so that it can transmit a second switching force 16 ′, here a closing force, which is directed oppositely to the first switching force 16 , i.e., the opening force.

[0196] “Oppositely oriented” is understood here to mean that the first switching force 16 and the second switching force 16 ′ each have a circumferential component relative to the control cam pivot axis 21 , wherein the circumferential component of the first switching force 16 and the circumferential component of the second switching force 16 ′ are oppositely oriented, ie in opposite directions.

[0197] Therefore, the control cam 20 comprises a second coupling surface 36' that is different from the first coupling surface 36. The coupling surfaces 36, 36' are arranged opposite each other with respect to the control pin 32, in particular with respect to its contour or cross-sectional contour perpendicular to the control cam pivot axis 21, and / or with respect to the longitudinal center axis 325. Thus, two switching and preferably prestressing forces 16, 16' can be alternately transmitted from the control cam 20 to the clamping arms 10, 10' via the control pin 32 for switching and / or prestressing.

[0198] Similar to the above, the coupling surfaces 39, 39' of the elongated hole 31, which according to this optional embodiment essentially correspond to the length of the side walls 311, 311', are arranged relative to each other with respect to the elongated hole 31, in particular with respect to its profile or cross-sectional profile perpendicular to the control cam pivot axis 21, and / or with respect to the longitudinal extension 310.

[0199] Since the control bolt 32 has a first coupling surface 36 extending in the direction of the control cam pivot axis 21 and configured and established for transmitting the first switching force 16 to the clamping arm 10, and a second coupling surface 36' which is different from the first coupling surface 36, extends in the direction of the control cam pivot axis 21 and configured and established for transmitting the second switching force 16' oriented opposite to the first switching force 16 to the clamping arm 10, the control bolt 32 serving as a coupling element can provide permanent forced guidance of the clamping arms 10, 10' during opening and closing, and preferably simultaneously provide pre-tensioning of the clamping arms 10, 10' into the open position or closed position.

[0200] exist Figure 28 and 29 It is concluded Figure 22 A top view of a detail of the control cam 20 of the clamping device 1 in the direction of the control cam pivot axis 21, wherein the control cam is Figure 28 is oriented in the closed preset position, while Figure 29 Orient in the open preset position.

[0201] Similar to About Figure 26 and 27 The description of the control cam 20, which is configured as an elongated hole 31, includes a first coupling surface 36, which extends between a first coupling surface boundary point 37 and a second coupling surface boundary point 38; and a second coupling surface 36', which extends between a first coupling surface boundary point 37' and a second coupling surface boundary point 38'. Also similar to Figure 26 and 27 The first coupling surface 36 is designed and configured to transmit a first switching force 16, here an opening force and a preload force into the open position, to the clamping arm 10. Furthermore, a second coupling surface 36′, which is different from the first coupling surface 36 and extends in the direction of the control cam pivot axis 21, is designed and configured to transmit a second switching force 16′, here a closing force and a preload force into the closed position, which is directed opposite to the first switching force 16, to the clamping arm 10.

[0202] Similarly, the coupling surfaces 36, 36' are arranged opposite each other with respect to the elongated slot 31, in particular with respect to its contour or cross-sectional contour perpendicular to the control cam pivot axis 21, and / or with respect to its longitudinal extension 310. Thus, two switching and preferably prestressing forces 16, 16' can be transmitted alternately from the control cam 20 to the clamping arms 10, 10' via the elongated slot 31 for switching and / or prestressing.

[0203] The coupling surface 36 corresponds to a portion of the length of the side wall 311 , while the coupling surface 36 ′ corresponds to a portion of the side wall 311 ′.

[0204] As far as applicable, all individual features shown in the exemplary embodiments can be combined with one another and / or exchanged without departing from the scope of the present invention.
