Description

[0001] PROTECTIVE DEVICE, TRANSPORT SYSTEM WITH A PROTECTIVE DEVICE AND PLANT FOR PROCESSING PHARMACEUTICAL CONTAINERS

[0002] The present invention relates to a protective device for a system for processing pharmaceutical containers, wherein the protective device is positioned or can be positioned in the system, in particular upstream of an outlet opening of the system for the containers, comprising a guide device which comprises or forms a transport path through which the containers can be conveyed, in particular in a jammed manner, and a blocking element arranged on the transport path, which can be transferred from a blocking position blocking the transport path for the containers into a release position releasing the transport path for the containers and vice versa.

[0003] Furthermore, the present invention relates to a transport system comprising a transport body, a drive device for the transport body and a protective device of the type described above, wherein the containers can be conveyed by means of the transport body, in particular in a jam-like manner, into or in the transport path.

[0004] Furthermore, the present invention relates to a system for processing pharmaceutical containers, which comprises a working space with at least one work station for the containers arranged therein and a wall for delimiting the working space, wherein an outlet opening is formed in the wall through which the containers can be conveyed by means of a transport system, in particular of the type described above.

[0005] In such a system, the containers can, for example, be processed in at least one processing station. The at least one station can, for example, comprise a weighing station, a filling station, a closing station, a checking station, a flanging station and / or a sorting station. The system comprises a work space defined by the wall, which can, for example, be a clean room. An outlet opening is formed in the wall through which the containers can be discharged from the work space. The containers can be discharged, for example, after processing. Discharge before or during processing is also conceivable, for example at a reject outlet. The outlet opening can also be arranged at transitions between work spaces.

[0006] Container processing systems typically require a protective device for operational safety reasons. The type of protective device depends primarily on the dimensions of the outlet opening and / or the distance within the work area from a hazardous area (e.g., due to moving machine parts).

[0007] It is known that straight conveyors without any protection against intrusion by operating personnel are installed at outlet openings. For example, slide gates are used at the outlet opening that are not tamper-proof.

[0008] Furthermore, S-shaped conveyor belts are being implemented as a barrier against intrusion by means of the conveyor belt's design. In practice, it has been shown that the back pressure of the containers being fed into such conveyor belts can be undesirably high, potentially causing damage. Furthermore, such protective devices have proven to be unsafe.

[0009] Better protection can be provided, for example, by hood-like covers mounted on the wall outside the work area, which can cover a container outlet. However, this restricts access to the outlet and requires more space.

[0010] Other types of protective devices, for example, include a bulkhead-like barrier element at the outlet opening that opens and closes according to sensor control. However, the construction of such protective devices is complex, resulting in high manufacturing costs and increased space requirements.

[0011] In a protective device of the type mentioned above, it is known that a locking element is arranged on the conveyor track, which releases the conveyor track in the release position. However, conventional protective devices have the disadvantage that operating personnel can reach into the work area through the outlet opening and manipulate the locking element. Such manipulation is carried out by operating personnel, for example, to manually rectify a malfunction in the system, since otherwise, in the event of a malfunction, an entire batch of processed containers might have to be discarded. However, this is not in line with occupational safety and the GMP guidelines for Good Manufacturing Practice (GMP).

[0012] As mentioned above, conventional systems and conventional protective devices have limitations in operational safety, or the design of sufficiently safe protective devices is complex due to manufacturing costs or space requirements. Increased space requirements also lead to operational limitations.

[0013] The object of the present invention is to provide a protective device of the type mentioned at the outset which offers greater operational safety while being as simple as possible in its construction.

[0014] This object is achieved according to the invention in a generic protective device in that the protective device comprises a securing element arranged on the transport track, which can be transferred from a securing position into a release position and vice versa, wherein the securing element in the securing position blocks the blocking element assuming the blocking position against movement into the release position and in the release position the blocking element can be transferred from the blocking position into the release position, and in that the securing element is positioned upstream of the blocking element in the feed direction of the containers, can be contacted by a supplied container and can be transferred from the securing position into the release position as a result of the movement of the container.

[0015] In the protective device according to the invention, when the blocking element assumes the blocked position, it is blocked by the additional securing element. The securing element can assume a securing position in which it blocks the blocking element in the blocked position. For this purpose, the blocking element and the securing element can, for example, be mechanically engaged with one another. An attempt at tampering from the outside is prevented because the operator can no longer move the blocking element into the release position by grasping the blocking element, as is the case with a conventional protective device. However, during operation of the system comprising the protective device, there is the possibility that a fed container may come into contact with the securing element. In particular, due to the dynamic pressure of subsequent containers fed in, the securing element is moved into the release position.When the safety element is in the release position, the locking element can be moved into the release position to clear the conveyor. This ensures proper functioning of the protective device while maintaining a simple design. External tampering by operating personnel is also made more difficult, thus increasing operational safety.

[0016] When used in a system for processing pharmaceutical containers, the containers are, for example, vials, syringes, cartridges, or ampoules. The containers are transported in an upright position, for example, although hanging or lying down is also possible. The protective device is used, for example, when processing vials to ensure stability.

[0017] It is advantageous if the locking element can only be moved from the locked position to the release position if the securing element has previously been moved from the secured position to the release position. This increases the operational reliability of the protective device and the system.

[0018] According to the invention, the securing element can be contacted by a supplied container and transferred into the release position as a result of the movement. For example, the securing element can be transferred into the release position using only a single container. It may be necessary to require two or more containers that contact the securing element to transfer it into the release position.

[0019] It is advantageous if the safety element is held in the release position by means of one or more containers. If the container(s) are in contact, the safety element will continue to assume the release position. This ensures the process reliability of the protective device during normal operation of the system.

[0020] Alternatively or additionally, it can be provided that the securing element is held in the release position by means of the locking element assuming the release position. For example, in this case, the securing element and the locking element can engage with each other by positive and / or frictional engagement. If the locking element returns to the locked position (for example, by a return element as explained below), the engagement can be released, allowing the securing element to return to the secured position (for example, by a return element as explained below).

[0021] It can be provided that the securing element, in the securing position, engages into the transport path, in particular from a left side and / or a right side of the transport path, relative to a transport direction of the containers in the transport path. For example, the securing element engages into the transport path from a left lateral guide and / or a right lateral guide and is arranged at least partially within the free cross-section of the transport path. It can be provided that the securing element, in the securing position, engages into the transport path only from one side, for example from the left side or the right side.

[0022] In the release position, the securing element is preferably arranged completely outside the free cross-section of the transport track, so that the transport track is completely free for the transport of the containers.

[0023] The guide device can comprise a guide body with a cover element, wherein the securing element, in the release position, is received in a receiving space covered by the cover element. The guide body forms, for example, a lateral guide, relative to the transport direction, on the left or right side of the transport path. In the release position, the securing element can be arranged in the receiving space below the cover body and, for example, can be immersed in it when it is transferred from the securing position to the release position. The securing element can be stored in the receiving space in a space-saving manner and is preferably secured against external manipulation by means of the cover element.

[0024] The securing element can, for example, comprise a sliding surface for the containers. The sliding surface is arranged obliquely relative to the transport direction of the containers in the transport path, particularly in the case of a straight transport path, or the sliding surface is designed in an arc shape, particularly in the case of a curved transport path. A container being fed in can contact the sliding surface and thereby apply a force to the securing element to transfer it into the release position.

[0025] To move the securing element, a preferred embodiment of the invention provides that the securing element is pivotable about a pivot axis on the guide device via interacting bearing elements. This bearing ensures reliable function of the securing element. The securing element can be pivoted back and forth between the securing position and the release position, out of the transport path or into the transport path (at least in sections).

[0026] The pivot axis is preferably aligned transversely and, in particular, perpendicularly to the transport path. For stationary transport, the pivot axis can, for example, be a vertical axis, in particular a vertical axis. The pivot angle of the securing element relative to the guide device can, for example, be up to 90° or more.

[0027] In a preferred embodiment of the invention, the pivot axis can be arranged on the securing element in a leading manner, for example with respect to the transport direction of the containers.

[0028] A preferred embodiment of the invention can provide for the securing element to be designed to be displaceable on the guide device via interacting bearing elements. This ensures reliable function of the securing element. By sliding, the securing element can be moved out of the transport path or (at least in sections) into the transport path when it is moved back and forth between the securing position and the release position.

[0029] The displacement direction can be aligned, for example, transversely and, in particular, perpendicularly to the transport direction of the containers. When the containers are transported in a vertical position, the displacement direction can be aligned, for example, parallel to a floor guide for the containers, in particular horizontally.

[0030] It is advantageous if the protective device comprises or forms a return element for providing a return force, under the action of which the securing element can be transferred from the release position to the securing position. This ensures reliable function of the protective device. In the absence of containers, the securing element can, for example, return to the securing position using the return element.

[0031] It is advantageous if the locking element can be moved from the locking position to the release position against the restoring force. The locking position thus defines a basic position to ensure the locking element remains locked in the absence of containers.

[0032] To achieve a structurally simple design, the return element is, for example, a mechanical spring element, although in practice, a spring element in the form of a coil spring or a leaf spring proves advantageous. The securing element extends along the conveyor track, for example, such that it can be contacted by at least two containers. For example, with a flow of containers through the conveyor track, the securing element can be held in the release position by a following container while a leading container passes the securing element.

[0033] In a preferred embodiment of the invention, the blocking element is arranged directly downstream of the securing element in the transport direction of the containers, whereby a container can simultaneously contact the securing element and the blocking element. For example, as will be discussed below, the blocking element can be moved from the blocking position to the release position as a result of the movement of the container. The containers can, in a sense, clear their own path through the transport path at the securing element and the blocking element.

[0034] To block the locking element, the securing element and the locking element preferably comprise cooperating blocking members that engage with each other, particularly mechanically, in the securing position of the securing element and in the locking position of the locking element. This enables a structurally simple design with reliable function of the protective device.

[0035] The engagement is released when the locking element assumes the release position, for example after pivoting or moving the locking element, so that the locking element can be moved into the release position.

[0036] The blocking members are designed, for example, as corresponding stop elements and can, for example, engage with each other in a form-fitting manner.

[0037] For example, the blocking members comprise a projection and a recess for the projection, wherein the projection engages in the recess when the securing element is in the locking position and rests against an edge of the recess. The projection can be arranged on the securing element and the recess on the blocking element, or vice versa.

[0038] The pivot axis of the securing element is arranged, for example, upstream of the locking element's locking element relative to the transport direction of the containers. The locking element's locking element can be arranged, for example, at the end of the securing element relative to the transport direction.

[0039] The blocking member of the blocking element can, for example, be arranged in a leading position on the blocking element with respect to the transport direction.

[0040] In a preferred embodiment of the invention, the guide device can comprise a guide body with a cover element, wherein the blocking members are arranged in a receiving space covered by the cover element. In this way, the blocking members are protected from external interference, which makes the protective device more tamper-proof and increases operational reliability.

[0041] It can be provided that the blocking element in the blocking position engages in the transport path in particular from a left side and / or a right side of the transport path, with respect to a transport direction of the containers.

[0042] Accordingly, as explained above using the example of the securing element, the blocking element can, for example, protrude from a left lateral guide and / or a right lateral guide into the transport path when it assumes the blocking position.

[0043] It can be provided that the locking element engages in the transport track only from one side, from the left or from the right.

[0044] The securing element in the securing position and the blocking element in the blocking position can, for example, engage in the transport path from the same side and be movable in the same direction for transferring into the release position and the release position from the transport path.

[0045] In the release position, the blocking element is preferably arranged completely outside the free cross-section of the transport path, so that the transport path is completely free for the containers.

[0046] The guide device can form a recess in which the blocking element is arranged in the release position, wherein the recess is arranged laterally next to the transport track and is formed, for example, by a guide body. The blocking element can be movable from the recess into the transport track in order to engage therein for transfer from the release position to the blocking position. However, it can be provided that the blocking element continues to engage in the recess in the blocking position, wherein in particular an engagement from the transport track into the recess is blocked in this way. This increases operational safety. The operator is prevented, or at least finds it more difficult, from reaching into the recess in order to manipulate the protective device.

[0047] The blocking element can advantageously be contacted by a supplied container and can be moved from the blocking position to the release position as a result of the movement of the container. Such a preferred embodiment of the invention has already been mentioned. After the blocking element has been released, the blocking element can, in a sense, be moved into the release position by the container itself. As explained in connection with the securing element, it can be provided that at least one container moves the blocking element. This can, in particular, be a single container.

[0048] The blocking element is advantageously held in the release position by means of one or more containers.

[0049] The blocking element advantageously comprises a sliding surface for the containers, which can be contacted to transfer them from the blocking position to the release position. The sliding surface is oriented at an angle relative to the transport direction of the containers in the transport path, particularly when the transport path runs in a straight line.

[0050] The blocking element can, for example, have an extension along the transport path such that it can be contacted by at least two containers.

[0051] Alternatively, the blocking element can, for example, have an extension along the transport path such that it can be contacted by only one container.

[0052] The guide device can comprise a guide body with a top-side cover element, wherein the blocking element protrudes beyond the cover element, pointing away from the transport track. The guide body forms, for example, a left or right lateral guide. The blocking element is, for example, arranged in the aforementioned recess and protrudes beyond the cover element, upwards when the transport is stationary. For example, the current position of the blocking element can thereby be detected and monitored from outside the system. In practice, it proves advantageous if the blocking element on the guide device is designed so that it can pivot about a pivot axis via interacting bearing elements. By pivoting, the blocking element can be pivoted, in particular, from the blocked position out of the transport track into the release position and vice versa into the transport track.

[0053] The swivel axis is aligned, for example, transversely and, in particular, perpendicularly to the transport path.

[0054] A pivoting angle of the locking element relative to the guide device can, for example, be up to 90° or more.

[0055] It can be provided that the pivot axis is arranged on the locking element in a leading manner with respect to the transport direction of the containers.

[0056] The blocking member of the locking element is arranged, for example, in the area of ​​the pivot axis on the locking element.

[0057] In a preferred embodiment of the invention, the locking element can be designed to be displaceable relative to the guide device, wherein preferably cooperating bearing elements are provided.

[0058] It is advantageous if the protective device comprises or forms a return element for providing a return force, under the action of which the locking element can be moved from the release position to the locked position. This ensures reliable function of the protective device while maintaining a simple design.

[0059] It can be advantageous if the locking element can be moved from the locked position to the released position against the restoring force. This defines the locked position as the basic position of the locking element and increases the operational reliability of the protective device.

[0060] In order to achieve a structurally simple design, the return element can be a mechanical spring element, for example a torsion spring.

[0061] For example, if the blocking element is designed such that it can be contacted by only one container, it could be provided that the blocking element is moved from the release position back to the blocking position after each container has passed through, particularly under the action of the return element. This allows the blocking element to have a compact design, blocking, for example, only part of the cross-section of the transport path in the blocking position. To further block the transport path for larger containers, an additional blocking element could be provided that engages the transport path from an opposite side.

[0062] Accordingly, the protective device can comprise a further blocking element, which preferably engages the transport path from a side opposite the blocking element in a blocking position and can be transferred into a release position and vice versa, wherein the further blocking element releases the transport path in the release position. For example, the transport path is blocked by the blocking elements each assuming the blocking position.

[0063] The further blocking element can, for example, be designed to correspond partially or completely to or have the same function as the blocking element. For example, at least one of the following can be provided, with reference to the above explanations: possibility of pivoting and / or displacement relative to the guide device, in particular with a bearing; arrangement in a recess of the guide device when the release position is assumed; transfer from the release position to the blocking position by means of a return element; transfer from the blocking position to the release position counter to the action of a return element; transfer from the blocking position to the release by means of a supplied container; provision of a sliding surface for the container; holding in the release position by means of at least one container.

[0064] The blocking element and the further blocking element can, for example, engage with one another when the respective blocking position is assumed, for example by positive and / or frictional engagement. In this case, the blocking element in particular can block the further blocking element against transfer from the blocking position to the release position. This makes it possible to dispense with a separate securing element for the further blocking element. For example, by transferring the blocking element to the release position, the engagement is released, so that the further blocking element can also be transferred to the release position. This preferably takes place in each case by contact with the supplied container. In a preferred embodiment of the invention, it can be provided that the blocking element is held in the release position by means of the securing element assuming the release position.For example, in this case, the securing element and the blocking element can be engaged with each other by positive and / or frictional engagement. If, for example, the force exerted by one or more containers on the securing element is removed (e.g., when the conveyor is empty), the securing element can be moved back into the securing position (e.g., by the return element as explained above). This allows the engagement to be released, allowing the blocking element to return to the blocking position (e.g., by the return element as explained above).

[0065] In one embodiment of the invention, it can be provided that a contour of the blocking element, viewed from above onto the transport path, has the shape of a circular arc. The angle of the circular arc can, for example, be approximately 20° to 80°, preferably approximately 30° to 50°.

[0066] The locking element can be designed as a hollow body, at least in sections. This keeps the mass of the locking element low, so that it can be reliably transferred from the locking position to the release position while a container is moving.

[0067] Applying a force to the locking element assuming the locking position can, for example, apply a force to the securing element directed in the direction of the securing position, so that the protective device can have a self-locking function.

[0068] The securing element and / or the blocking element can be arranged, for example, on a straight section of the transport path. It can be provided that the securing element and / or the blocking element is / are arranged on a curved section of the transport path.

[0069] The protective device can, for example, comprise or form a tunnel through which the containers can be moved in the transport path and which covers the blocking element and / or the securing element. The tunnel can increase the operational reliability of the protective device. For example, an operator can be prevented from acting on the blocking element and / or the securing element from the outside. The guide device can comprise two guide bodies arranged at a distance from one another, between which the transport path is formed. The guide bodies form, for example, a left lateral guide and a right lateral guide. Each guide body can form a wall of the tunnel in sections. The tunnel can accordingly be divided into two parts, with each part being provided by a guide body.

[0070] The protective device is advantageously designed so that it can be used in a variety of ways with different containers. Components of the protective device can have container-specific properties. In particular, it is provided that two or more format sets with respective format parts are present, with the format parts of different format sets differing from one another in at least one container-specific property.

[0071] For example, the guide bodies of the guide device are format parts.

[0072] It is conceivable that the locking element is a format part.

[0073] It may be provided that the securing element is a format part.

[0074] In another advantageous embodiment, it can be provided that the security element is format-independent.

[0075] The protective device can be designed without sensors and free of drives for the securing element and / or the locking element.

[0076] The protective device may include a sensor device with which the respective position of the securing element and / or the blocking element can be determined. Depending on a signal from the sensor device, the transport system or the installation can be controlled and / or regulated, for example.

[0077] The protective device is advantageously suitable for retrofitting existing systems. It is conceivable that the guide device with safety element and locking element could be installed on an existing system and replace an existing conveyor track, whereby a conveyor body conveying the containers advantageously does not need to be replaced. As mentioned at the beginning, the invention also relates to a transport system.

[0078] A transport system according to the invention comprises a transport body, a drive device for the transport body and a protective device of the type described above, wherein the containers can be conveyed by means of the transport body, in particular in a jam-like manner, into or in the transport path.

[0079] The transport body can be designed in various ways. For example, it could be a transport wheel, particularly a star wheel, a screw conveyor, a linear conveyor, a cell chain with transport links, or a mover in a magnetic levitation system. Other types of transport bodies are also conceivable.

[0080] As further mentioned, the invention also relates to a system.

[0081] A system according to the invention for processing pharmaceutical containers comprises a work space with at least one processing station for the containers arranged in the work space and a wall for delimiting the work space. An outlet opening is formed in the wall through which the containers can be conveyed by means of a transport system of the type described above. The protective device is arranged inside or outside the work space, and the transport path extends to the outlet opening or passes through the outlet opening. Depending on the available installation space, the protective device could be positioned inside or outside the work space.

[0082] The advantages mentioned in connection with the explanation of the protective device according to the invention can also be achieved with the transport system according to the invention and with the plant according to the invention. Advantageous embodiments of the transport system according to the invention and the plant according to the invention result from advantageous embodiments of the protective device according to the invention. In both cases, reference can be made to the above explanations.

[0103] Figure 18: a representation corresponding to Figure 6 in a further preferred

[0104] Embodiment of the protective device according to the invention.

[0105] Figure 1 shows a schematic representation of an advantageous embodiment of the system according to the invention, designated overall by reference numeral 100. In this case, the system 100 is configured to process pharmaceutical containers 102. The containers 102 in this case are vials 104. However, the scope of application of the present invention is not limited thereto.

[0106] The system 100 comprises a frame 106 positioned on a surface 108 of a room, for example, a laboratory. A wall 110 defines a workspace 112 above the frame 106. The workspace 112 can be, for example, a clean room, with the wall 110 being, for example, the wall of a machine guard.

[0107] At least one processing station 114 for processing the containers 102 is arranged in the work space 112. In the present example, the processing station 114 is a schematically illustrated flanging station 116. The containers can be transported into the work space 112 using transport bodies via an inlet 118.

[0108] In the present example, the system 100 has a plurality of outlets 120 for the containers 102. For example, a reject outlet 121 is located upstream of the flanging station 116. Another reject outlet 122 is located downstream of the flanging station 116. On the output side, for example, two outlets 120 are provided, which serve to store processed containers 102 sealed with crimp caps. Reference numerals 123, 124 identify the removal areas at these outlets 120. Corresponding removal areas are present at the reject outlets 121, 122.

[0109] It is understood that the number of outlets 120 as well as the type of processing station 114 are merely exemplary.

[0110] An outlet opening 126 is formed in the wall 110 at each outlet 120. The containers 102 can pass through the outlet opening 126 from the work space 112 to the respective removal area 121 to 124, from where they can be manually removed by an operator or further processed automatically.

[0111] In practice, the system 100 is subject to safety regulations. Depending on the size of the outlet opening 126 and the distance of machine components in the working space 112 from the outlet opening 126, it must be ensured that operating personnel cannot reach into the working space 112. If the outlet openings 126 are sufficiently small and / or the distance from machine components is large, a protective device may be unnecessary under certain circumstances.

[0112] The present invention relates to protective devices required to ensure operational safety in the system 100. Naturally, the protective devices described here are also suitable for systems where a protective device is not absolutely necessary. Even in such systems, they contribute to increasing operational safety.

[0113] The system 100 comprises a transport system 128 assigned to a respective outlet 120. The transport system 128 comprises a transport body 130 and a drive device 132 for driving the same.

[0114] The respective transport system 128 is shown and explained in a preferred embodiment according to the invention and in the present case.

[0115] Furthermore, the transport system 128 comprises a preferred embodiment of the protective device 134 according to the invention. In the present example, the transport body 130 is a transport wheel 136 that can be driven to rotate about a vertical axis. The containers are picked up by the transport wheel 136 in a conventional manner.

[0116] The protective device 134 comprises a guide device 138 which forms a transport path 140 for the containers 102.

[0117] The transport system 128 is configured such that the containers 102 are moved by the transport body 130 in a stacked manner through the transport path 140. This can be understood, in particular, to mean that a container 102 leading in the transport path is pushed through the transport path 140 by the following containers 102 and, in turn, contributes to pushing a preceding container 102 through the transport path 140.

[0118] Deviating from the present illustration, the transport of the containers 102 may be provided in a different manner. For example, the transport body 130 may be or include a screw conveyor. The use of a conveyor belt, a cell chain with transport links, or a mover in a magnetic levitation transport system is also conceivable.

[0119] The transport path 140 extends to the outlet opening 126. When the transport path 140 is released, the containers 102 can reach the outlet opening 126 and preferably pass through it.

[0120] In this case, the transport track 140 has a floor guide 142 on which the containers 102, the stable vials 104, are moved. However, the invention is not limited to this. Alternatively, a suspended or horizontal transport of containers 102 is conceivable.

[0121] In the transport path 140, the containers 102 are moved along a transport direction 144. The transport direction 144 can vary depending on the shape of the transport path 140.

[0122] The protective device 134 comprises the guide device 138, which in the present embodiment comprises a first guide body 146 and a second guide body 148. The first guide body 146 is a left guide body for left lateral guidance, relative to the transport direction 144, and the second guide body 148 is a right guide body for right lateral guidance, relative to the transport direction 144. The guide bodies 146, 148 are spaced apart from one another and define the transport path 140 between them, which is delimited at the bottom by the floor guide 142. The transport path 140 is dimensioned such that the containers 102 can be moved therein with minimal play.

[0123] In the protective device 134, the guide bodies 146, 148 are designed such that the transport path 140 comprises a curved section 150 on the supply side, which forms a curve and is located downstream of the transport body 130. Adjoining the curved section 150 is a rectilinear section 152, extending up to the outlet opening 126.

[0124] On the upper side, in this case facing away from the floor guide 142, the guide bodies 146, 148 each comprise a substantially plate-shaped cover element 154. In the guide body 146, the cover element 154 covers a receiving space 156. The receiving space 156 merges in the transport direction 144 into a recess 158 of the guide body 146, which also extends in the region of the cover element 154, so that the recess 158 is not covered by the cover element 154.

[0125] To increase operational safety, the protective device 134 comprises a securing element 160 and a blocking element 162. Relative to the transport direction 144, the containers 102 first pass through the securing element 160 and then through the blocking element 162. The blocking element 162 only releases the transport path 140 if the containers 102 first pass through the securing element 160. This is explained below. The blocking element 162 is largely protected against external manipulation by operating personnel who reach into the working space 112 through the outlet opening 126.

[0126] In this case, the securing element 160 has a securing body 164, which can be configured, for example, in a disc shape. The securing body 164 is dimensioned such that it can be accommodated in the receiving space 156 below the cover element 154, wherein it is movable back and forth relative to the guide body 146.

[0127] In particular, the securing element 160 is pivotally mounted on the guide body 146. Corresponding bearing elements in this case are a bearing pin 166 of the guide body 146 and a bearing receptacle 168 of the securing element 160. The bearing pin 166 defines a pivot axis 170. The pivot axis is oriented transversely and in particular perpendicularly to the transport path 140 and is, for example, a vertical axis, in particular a vertical axis.

[0128] The pivoting of the securing element 160 can occur counter to the restoring force of a restoring element 172. In this case, the restoring element 172 is a mechanical spring element, designed as a helical spring 174. The helical spring 174 is supported on the guide body 146 and the securing element 160.

[0129] The securing element 160 can assume a securing position without the presence of a container being fed in (Figure 3). In this case, the securing element is subjected to the restoring force in such a way that it partially engages the free cross-section of the transport path 140. In this case, the securing element 160 engages only relatively slightly. However, it is important that a container being fed in can contact the securing element 160.

[0130] For contact through the container 102, the securing element 160 has a sliding surface 176 which is oriented obliquely with respect to the transport direction 144 and, in the present case, is planar.

[0131] The pivot axis 170 is arranged on the securing element 160 in a leading position with respect to the transport direction 144 (Figure 4). The return element 172 is arranged in this case on an end portion of the securing element 160 facing away from the pivot axis 170.

[0132] A supplied container moves in the transport path 140 and comes into contact with the sliding surface 176. As the container 102 continues to move, the securing element 160 is subjected to a force and pivots against the action of the return element 172. If the force from a container is removed, the securing element 160 returns to its original position.

[0133] Alternatively or additionally, the securing element 160 can be held in the release position, for example by means of the locking element 162, as mentioned below.

[0134] The locking element 162 is functionally configured to correspond to the securing element 160. As can be seen, for example, from Figures 4 to 7, the locking element 162 in this case has approximately the shape of a flap that can be actuated by the containers 102. To save weight, the locking element 162 can be configured in sections as a hollow body (Figure 4).

[0135] The locking element 162 is pivotally mounted on the guide body 146. Corresponding bearing elements are a bearing pin 178 of the guide body 146 and a bearing receptacle 180 of the locking element 162.

[0136] The bearing pin 178 defines a pivot axis 182. The pivot axis 182 is aligned transversely and in particular perpendicularly to the transport path 140 and in this case parallel to the pivot axis 170. The pivot axis 182 can be a vertical axis, in particular a vertical axis.

[0137] The locking element 162 can be pivoted relative to the guide body 146 against the action of a return element 184. In this case, the return element 184 is a mechanical spring element configured as a torsion spring 186 (Figure 8). The torsion spring 186 surrounds the bearing pin 178 and is fixed thereto. A leg not shown in the drawing engages the locking element 162.

[0138] The blocking element 162 is dimensioned such that it is arranged in the recess 158, protruding upwards above the cover element 154 in this case. It may prove advantageous, for example, if the blocking element 162 is designed to be at least as high as the containers 102, preferably higher.

[0139] The pivot axis 182 is arranged in a leading manner on the locking element 162, relative to the transport direction 144.

[0140] In a top view of the guide device 138, the locking element 162 essentially has the shape of a circular sector. The angle of the circular sector is, for example, approximately 30° to 50°. The locking element 162 widens from the end section in which the pivot axis 182 is arranged.

[0141] Under the action of the return element 184, the blocking element 162 can engage the transport path 140. This makes it possible to completely or substantially completely block the free cross-section of the transport path 140. The blocking element 162 comprises a sliding surface 188 in the transport path 140. The sliding surface 188 is oriented obliquely with respect to the transport direction 144 and, in this case, is planar.

[0142] If a container 102 comes into contact with the sliding surface 188, the locking element 162 is pivoted out of the transport path 140 and into the recess 158, so that the transport path 140 is released for the container 102.

[0143] The interaction of the securing element 160 and the locking element 162 as well as their further design are explained below.

[0144] The locking element 162 can be blocked against pivoting movement by means of the securing element 160. For this purpose, the securing element 160 comprises a blocking member 190, and the locking element 162 comprises a corresponding blocking member 192. The blocking members 190, 192 can cooperate to secure the locking element 162.

[0145] As can be seen, for example, in particular from Figures 3, the blocking members 190, 192 are corresponding stops which can be mechanically engaged with one another.

[0146] The blocking member 190 is arranged at the end of the securing element 160 relative to the transport direction 144. The blocking member 190 is designed as a projection 194.

[0147] The blocking member 192 is arranged in a leading manner in the region of the pivot axis 182 on the locking element 162 with respect to the transport direction 144. The blocking member 192 is designed as a recess 196 into which the projection 194 can engage.

[0148] The blocking members 190, 192 can be disengaged so that the transport path 140 for the containers 102 can be released.

[0149] During intended use, as long as the containers 102 do not yet contact the securing element 160 and the blocking element 162, these elements 160, 162 each assume a home position. It is assumed that the containers 102 are still arranged upstream of the securing element 160 on the upstream side (Figure 3). Under the action of the return element 184, the blocking element 162 is pivoted into the transport path 140 and blocks it. The home position corresponds to a blocking position of the blocking element 162, in which the transport path 140 is blocked.

[0150] In the locked position, the locking element continues to engage in the recess 158. An operator cannot therefore reach into the recess 158 from the outside, so that the locking element 162 is protected against manipulation.

[0151] The securing element 160 is pivoted into the transport path 140 under the action of the return element 172. As a result, the blocking members 190, 192 are mechanically engaged with each other. The projection 194 engages in the recess 196 and rests against its edge. The securing element 160 thereby secures the locking element 162 against pivoting out of the transport path 140. The basic position of the securing element 160 is accordingly also referred to as the securing position.

[0152] The transport path 140 can be released under the movement of the containers 102. In a sense, the containers 102 clear their way through the transport path 140 themselves.

[0153] A supplied container contacts the sliding surface 176. This results in the engagement between the blocking members 190, 192 being released (Figures 4 and 5). The securing element 160 is pivoted about the pivot axis 170 by the force applied by the container 102. The pivoting occurs counter to the restoring force of the restoring element 172 into the receiving space 156 (Figures 4 and 5). The blocking members 190, 192 are disengaged, which is why the pivoted position of the securing element 160 can be referred to as the release position.

[0154] The securing element 160 can be held in the release position by the containers 102 as long as they contact the sliding surface 176. While one container 102 passes the securing element 160, the next container 102 reaches the sliding surface 176, so that the blocking members 190, 192 remain disengaged (Figure 6).

[0155] Alternatively or additionally, it can be provided that the securing element 160 is held in the release position by means of the locking element 162 (see Figure 7) assuming the release position. For example, the securing element 160 and the locking element 162 can engage with each other by positive and / or frictional engagement and, for this purpose, comprise corresponding blocking members, which, for example, are formed with the same function as the blocking members 190, 192. If the locking element 162 returns to the locked position by the return element 184, the engagement can be released, so that the securing element 160 can also return to the secured position by means of the return element 172.

[0156] The leading container 102 then comes into contact with the sliding surface 188 of the locking element 162 and can apply a force thereto (Figure 6). This causes the locking element 162 to pivot about the pivot axis 182. The pivoting movement is made possible by the fact that the blocking members 190, 192 no longer abut one another and can block the pivoting movement of the locking element 162.

[0157] As a result of the movement of the container 102, the locking element 162 pivots from the locking position into the recess 158 to a position in which the leading container 102 is first moved through the transport path 140 to the outlet opening 126. Subsequent containers also contact the locking element 162 and are in turn moved to the outlet opening 126 under the thrust of subsequent containers 102. As the containers 102 are moved in a jammed state, the securing element 160 remains in the release position and the locking element 162 remains in the release position (Figure 7).

[0158] The protective device 134 comprises, as can be seen particularly from Figures 2 and 8, a tunnel 198 to further increase operational safety. The tunnel 198 is positioned in the working space 112 upstream of the outlet opening 126. In the present case, the tunnel 198 comprises a wall 200 having two sections 202, 204.

[0159] Here, the guide body 146 forms the section 202 and the guide body 148 forms the section 204. This enables a structurally simple design of the tunnel.

[0160] The tunnel 198 covers the locking element 162 and the guide bodies 146, 148 in the area of ​​the securing element 160, so that the elements 160, 162 are even more effectively protected against external manipulation. This is largely impossible with the securing element 160 because it is located in the receiving space 156 below the covering element 154, preventing direct access by an operator.

[0161] The tunnel 198 forms part of the protective device 134, particularly when the containers 102 are arranged therein. For example, if the containers 102 have moved the securing element 160 into the release position, the locking element 162 could possibly be opened from the outside if the blocking members 190 and 192 are no longer engaged with each other. Even if the operator could reach through the exit opening 126, a passage would still be blocked due to the tunnel 198 and the containers 102 arranged therein. Due to the transport wheel 136, the containers 102 in the jammed state cannot be moved inward opposite to the transport direction 144, neither when the transport wheel 136 is active nor when the transport wheel 136 is stationary.

[0162] It is advantageous if the protective device 134 comprises a plurality of format sets 206. Each format set 206 can comprise several format parts, wherein the format parts of different format sets 206 differ from one another in their container-specific properties. This allows for a structurally simple and versatile conversion of the protective device 134 between different formats of containers 102.

[0163] It can also be provided that a respective format set 206 covers a predetermined format range.

[0164] Format parts can be, for example, the guide bodies 146, 148, the locking element 162, and the tunnel 198 (for example, sections 202 and 204). In one advantageous implementation, the securing element 160 is, for example, format-independent. In a different implementation, the securing element 160 can also be a format part.

[0165] Further preferred embodiments of the device and transport system according to the invention are explained below with reference to Figures 9 to 17. Identical reference numerals are used for identical or equivalent features and components. The advantages explained in connection with the transport system 128 and the protective device 134 are also achieved with the protective devices and transport system explained below, so that reference can be made to the above explanations to avoid repetition. Only the essential differences will be discussed.

[0166] A transport system according to the invention in a preferred embodiment is partially illustrated in Figures 9 to 12 and designated there by reference numeral 210. The transport system 210 comprises a preferred embodiment of the protective device according to the invention, designated by reference numeral 212. From a functional perspective, the functioning of the protective devices 134 and 212 is identical.

[0167] Unlike the protective device 134, the return element 172 for the securing element 160 in the protective device 212 is not designed as a helical spring 174, but as a leaf spring 214 (Figures 11 and 12).

[0168] The guide body 146 is partially open in the protective device 212 (Figure 12). A cover element 216 arranged at the bottom has a recess 218 in the area of ​​the securing element 160 and the locking element 162. In practice, this has been shown to improve the cleaning properties of the protective device 212.

[0169] Figures 13 to 17 show a preferred embodiment of a protective device according to the invention, designated by reference numeral 220. The protective device 220 can be a component of the transport system 128 or 210 according to the invention.

[0170] In the protective devices 134, 212, the second section 152 of the transport path 140 is designed to be straight. In contrast, the transport path 140 in the protective device 220 has a second section 222 that is formed in the shape of an S-shaped chicane.

[0171] Unlike the protective devices 134, 212, the securing element 160 and the locking element 162 are arranged on the right lateral guide formed by the guide body 148. However, this is not restrictive for the present invention. Such an arrangement on a right lateral guide could also be provided for the protective devices 134, 212. Conversely, the elements 160, 162 could be arranged on a left lateral guide in the protective device 220.

[0172] In the protective device 220, the securing element 160 is slidably mounted on the guide body 148 in order to be transferred from the securing position to the release position and vice versa. Corresponding bearing elements include bearing pins 224 on the guide body 148, which engage with bearing receptacles 226 of the securing element 160. The bearing receptacles 226 are designed as elongated holes.

[0173] The restoring force is applied by two restoring elements 172 configured as coil springs 174. The sliding surface 176 is adapted in shape to the contour of the transport track 140 at section 222 and is accordingly curved. The locking element 162 is arranged on the output side of the S-shaped section 222.

[0174] In functional terms, the protective device 220 is designed to correspond to the protective devices 134 and 212. First, the securing element 160 is moved from the securing position to the release position under the action of a container 102, thereby releasing the engagement of the blocking members 190, 192. Subsequently, the container 102 moves the locking element 162 from the locking position to the release position.

[0175] Figures 14 and 15 show the situation when the container 102 initially comes into contact with the securing element 160 from above and from below, respectively (each as a sectional view).

[0176] Similarly, Figures 16 and 17 show the situation with the transport path 140 released from above and from below, respectively.

[0177] Figure 18 shows a preferred embodiment of a protective device according to the invention, designated by reference numeral 230, in a partial view and at a time corresponding to the time shown in Figure 6 for the protective device 134. The protective device 230 can be a component of the transport system 128 or 210 according to the invention. For this purpose, Figure 18 also shows sections of the transport body 130.

[0178] In the protective device 230, the blocking element 162 has a compact design compared to the protective devices 134, 212, and 220. Along the transport direction, the blocking element 162 is extended such that it can be contacted by only one container 102. It is therefore only short in length.

[0179] As a result, the blocking element 162 is dimensioned in this case such that in the blocking position shown in Figure 18, it only partially blocks the free cross-section of the transport path 140, in the present example approximately half.

[0180] To further block the transport path 140, the protective device 230 comprises a further blocking element 232. The further blocking element 232 is arranged on a side of the transport path 140 opposite the blocking element 160, in this case on the right lateral guide of the guide device 138. The further blocking element 232 also allows wider transport paths 140 for containers 102 with larger diameters to be covered with short blocking elements 162, 232 and relatively small guides, in particular since in such an embodiment no two containers 102 have to rest against the blocking elements 162, 232.

[0181] The additional blocking element 232 can also be moved from a blocking position blocking the transport path 140 for the containers 102 to a release position releasing the transport path 140, and vice versa. For this purpose, the additional blocking element 232 is designed to be largely functionally identical to the blocking element 162.

[0182] For example, the additional locking element 232 can be pivoted relative to the guide device from the locking position shown in Figure 18 about a pivot axis 234 relative to the guide device 138 into the release position. The guide device 138 is pivotably mounted via corresponding bearing elements.

[0183] In the locked position, the further locking element 232 blocks approximately half of the free cross-section of the guide track 140. In the released position, the further locking element 232 is arranged in a recess 236 of the guide body 148.

[0184] The pivoting occurs under the action of a supplied container 102, which contacts a sliding surface 238 of the further blocking element 232. In this case, this also has approximately the shape of a flap that can be actuated by the containers 102 and held in the release position. The extension along the transport direction 144 is such that only one container 102 contacts the further blocking element 232.

[0185] A return element is provided (not shown), under the action of which the pivoting from the release position to the blocking position takes place and against the action of which the pivoting from the blocking position to the release position takes place.

[0186] The locking element 162 and the additional locking element 232 can engage with each other when the respective locking position is assumed, in this case by positive locking. For this purpose, corresponding blocking members 240, 242 are provided, which are designed as stop elements. In this case, the locking element 162 secures the additional locking element 232. This eliminates the need for a separate securing element for the additional locking element 232.

[0187] During operation, a supplied container 102 contacts the locking element 162 and begins to move it into the release position, thereby releasing the engagement with the additional locking element 232. Subsequently, the container 102 contacts the additional locking element 232 to also move it into the release position.

[0188] In the protective device 230, the securing element 162 folds back toward the locking position due to its small extension in the transport direction 144 after a container 102 has passed through. To prevent this, it can be provided that the locking element 162 is held in the release position by means of the securing element 160, which assumes the release position.

[0189] For example, the securing element 160 and the blocking element 162 can engage with each other by positive and / or frictional engagement. For this purpose, blocking elements in the form of stop elements are provided, for example, as explained using the example of the blocking elements 190, 192, 240, 242. As long as the securing element 160 assumes the release position, the blocking element is held in the blocking position. It is advantageous here if the securing element 160 can be contacted by two consecutive containers. For example, the securing element 160 has a small pivot angle and a format-independent contour.

[0190] If the force acting on the securing element 160 is removed, for example, when the conveyor track 140 is empty, the securing element 160 can be moved back into the securing position. This releases the engagement with the locking element 162, allowing the locking element 162 to return to the locking position, where it is again blocked by the securing element 160.

[0191] It is understood that such an engagement between the locking element 162 in the release position and the securing element 160 in the release position is also conceivable for the other protective devices 134, 212 and 220. List of reference symbols
