[0003] CONTROL DEVICE, PROCESSING DEVICE WITH A CONTROL DEVICE AND METHOD FOR OPERATING A PROCESSING DEVICE

[0004] The present invention relates to a control device for controlling an interior enclosed by a wall of a processing device for pharmaceutical containers, in particular a sterilization tunnel for sterilizing the containers.

[0005] Furthermore, the present invention relates to a processing device for pharmaceutical containers, which may in particular be a sterilization tunnel, and to a method for operating the processing device.

[0006] In the processing equipment, the containers can be subjected to a predefined processing process. The processing equipment can be configured in various ways. The invention is explained below, particularly using the example of a sterilization tunnel. However, the present invention is not limited to this configuration of the processing equipment. The pharmaceutical containers can be, for example, vials, syringes, cartridges, or ampoules. The containers can be stable or unstable.

[0007] A sterilization tunnel is used, for example, to sterilize pharmaceutical containers, which are supplied in bulk, before further processing—especially weighing, filling, and sealing. The containers are fed unsterilized into a sterilization tunnel, such as the one described in DE 4217054 A1. The sterilization tunnel can include a preheating zone, a sterilization zone, and a cooling zone. It is desirable to be able to control the sterilization process as closely as possible. This allows any problems to be detected early. Problems can include, for example, unplanned transport of the containers inside the tunnel via a conveyor system, glass breakage, or an unintentional build-up of containers inside. If necessary, countermeasures can be taken. Even in processes that run without errors, it can be desirable to be able to inspect the interior.This serves, for example, for documentation purposes during container production. Information about the process can thus be stored, preferably linked to the produced batch. 39524. BUS. P110PC.

[0010] In a sterilization tunnel, the heating and cooling zones may have windows through which a user can see inside. This is not possible in the sterilization zone because the very high temperature of 300 °C or more (for example, 320 °C to 340 °C) required for the sterilization process necessitates a closed, windowless space to ensure the required thermal insulation.

[0011] The object of the present invention is to provide a control device for a processing device for pharmaceutical containers, whereby the process reliability can be increased via the control device. Furthermore, it is an object of the present invention to provide a processing device with a control device and a method for operating the processing device.

[0012] This problem is solved by a control device according to the invention for controlling an interior enclosed by a wall of a processing device for pharmaceutical containers, in particular a sterilization tunnel for sterilizing the containers, comprising a camera unit with which images of the interior can be created, a cover element which is configured to be arranged inside the interior on a first side of the wall which faces the interior and which has at least one optical window, and a holding unit which is configured to be positioned on a second side of the wall opposite the first side, wherein the camera unit is movably held on the holding unit and can be moved from a parked position to a control position and vice versa.wherein the camera unit is arranged outside the interior in the parking position and, in the monitoring position, extends at least partially through a passage opening in the wall and engages in the cover element in such a way that a field of view of the camera unit is directed through the at least one optical window into the interior.

[0013] The control device according to the invention is explained below using the example of its intended use on the processing device, which has a wall and an interior enclosed by the wall. According to the present invention, the control device comprises a cover element on the first side of the wall, which faces the interior. The camera unit can be moved from preferably at least one parking position, in which it is arranged outside the wall, to a control position. In the control position, the camera unit extends at least partially through a through-opening in the wall and engages the cover element. The camera unit can be viewed through the at least one optical window of the cover element. 39524. BUS. P110PC

[0016] Capture images of the interior. These images serve for process control. In case of any problems, countermeasures can be taken. Furthermore, it is preferable to add the images to a data set relating to the processing of the containers, created, for example, for the processed batch. In the parked position, the camera unit is located outside the interior. If the processing equipment is a sterilization tunnel and the control unit is located at the sterilization zone, this allows the interior to be sterilized at a high temperature without damaging the camera unit. To capture images of the interior, the camera unit can be moved to the control position, particularly during the transport of containers through the sterilization zone. In this case, the temperature inside the interior can be the same as or lower than during the initial sterilization.The camera unit only needs to temporarily assume the monitoring position and remains undamaged in this case. However, to increase operational reliability, which will be discussed later, cooling of the camera unit is preferable.

[0017] The present invention provides the possibility of controlling and, in particular, monitoring the process indoors using the control device. In this way, the requirements of Annex 1 of the Good Manufacturing Practice (GMP) guidelines can preferably be met, according to which visual inspection must be provided in enclosed spaces without any other means of viewing.

[0018] The images captured by the camera unit can be single shots. Alternatively or additionally, multiple shots and / or videos of the interior can be created.

[0019] The cover element can, for example, be designed as a sleeve open on one side or comprise such a sleeve. The camera unit can be moved into the sleeve when it is transferred to the inspection position.

[0020] The sleeve preferably engages the through-hole from the first side of the wall or extends through the through-hole.

[0021] In the control position of the camera unit, a gap can preferably be formed between the cover element and a camera housing of the camera unit, 39524. BUS. P110PC

[0023] - 4 - in particular an air-filled space. This is advantageous for thermally insulating the camera unit relative to the hot interior environment.

[0024] The cover element can, for example, be designed in the shape of a hood or a cap.

[0025] The cover element is preferably made of a metal material suitable for pharmaceutical applications. Stainless steel is one example of a suitable material.

[0026] It is understood that the cover element may be made of other materials, for example at least one optical window.

[0027] The at least one optical window comprises, for example, a borosilicate glass, which preferably has a thickness of 1 mm or more up to approximately 5 mm.

[0028] The borosilicate glass is preferably sealed relative to an opening in the cover element by means of at least one sealing element. For example, the borosilicate glass is arranged between sealing elements and mounted by means of a retaining part that is otherwise fixed to the cover element. The retaining part is, for example, frame-shaped.

[0029] The cover element can be attached directly or indirectly to the wall and / or the mounting unit. For this purpose, for example, a flange is provided that rests against an edge of the opening. The connection can be made in various ways, such as by bolting.

[0030] It is advantageous if the control device includes a sealing unit to provide a particularly gas-tight seal between the wall and the cover element. This prevents a thermal bridge through the opening, which could otherwise cause an undesirable drop in the interior temperature.

[0031] The mounting unit can be fixed to the wall and / or to an insulating body located on the other side. This ensures a reliable relative position between the camera unit and the wall. The mounting unit is stationary relative to the wall. 39524. BUS. P110PC

[0034] Alternatively, it may be stipulated, for example, that the holding unit is free from any connection to the wall and / or the insulating body. In such a case, the holding unit is, for example, fixed to a support structure of the processing equipment.

[0035] The insulating body can be specifically designed to insulate the wall on the second side, which proves particularly advantageous in sterilization tunnels.

[0036] In a structurally simple yet robust design, the holding unit can, for example, comprise or form a frame made of interconnected structural elements.

[0037] It is advantageous if the holding unit includes or forms at least one guide element, and if the camera unit is guided directly or indirectly on a corresponding guide element. This ensures reliable operation of the control device. The at least one guide element is, for example, designed as a profile element. The camera unit can be held directly or indirectly (for example, via a retaining element) on a corresponding guide element. The holding unit can, for example, include two guide elements spaced apart from each other. By sliding, the camera unit can be moved from the control position to the parked position or to an intermediate position, and vice versa.

[0038] It is conceivable that the camera unit can be manually moved by a user from the parking position to the control position and vice versa.

[0039] It can be advantageous if the control device includes an electrically controlled drive unit that allows the camera unit to be moved, and in particular shifted, relative to the holding unit. This makes it possible to operate the control device at least partially automatically. The drive unit can, for example, be electrically powered and include a lifting spindle motor. Other configurations are conceivable. Using the drive unit, the control device can, for example, be moved, and in particular shifted, from the control position to the park position or to an intermediate position, and vice versa.

[0040] The control device advantageously includes a user interface coupled to the drive unit and / or the camera unit, wherein the drive unit can be manually activated by the user to move the camera unit – for example, 39524. BUS. P110PC

[0043] Moving the camera unit from the control position to the park position or an intermediate position and vice versa, and / or allowing the user to manually create images of the interior. The user can operate the control unit, which is, for example, the control unit of the processing equipment for the containers. The control unit enables user-friendly and intuitive operation of the control device. Preferably, this includes the ability to move (or have moved) the camera unit and / or to create images.

[0044] The control device may preferably include or be coupled to a data processing unit, wherein the drive unit and / or the camera unit can be actuated depending on a control program executable by the data processing unit. Such control can, in particular, be automated without user intervention. For example, times can be defined at which the camera unit assumes a desired position (parked position or control position) and / or at which images are taken.

[0045] The control device preferably includes or is coupled to a data processing unit, wherein recordings made from the interior by the camera unit in its control position can be stored in a data memory of the data processing unit. This has already been indicated. The recordings can, for example, be added to a data set about the processing of the containers. Advantageously, the data set is stored in the data memory in a tamper-proof manner.

[0046] The camera unit can be designed in various ways. For example, it could be a camera unit for taking pictures in the visible light spectrum and / or an IR (infrared) camera unit.

[0047] Alternatively or additionally, it is advantageous for the control device to include a cooling unit for actively cooling the camera unit, at least when it is in the control position. This prevents the camera unit from overheating when it is in the control position. For example, a cooling fluid, particularly compressed air, is used. Alternatively or additionally, liquid cooling is conceivable. Furthermore, the use of a thermoelectric effect to cool the camera unit is conceivable as an alternative or additionally.

[0048] The camera unit can include the cooling unit. 39524. BUS. P110PC

[0051] The holding unit advantageously comprises a sleeve or socket that can be inserted or inserted from the second side of the wall into the wall or into an insulating body arranged on the second side, with the camera unit passing through the sleeve or socket in the inspection position. The through-opening can, for example, be lined on an inner circumferential surface by means of the sleeve or socket.

[0052] In the parked position, the camera unit is positioned outside the sleeve or socket. To move it to the inspection position, the camera unit can be guided through the sleeve or socket.

[0053] The control device preferably comprises a locking element with which, in a closed position, the opening in the wall and / or an opening in an insulating body located on the other side of the wall can be closed when the camera unit is in the parked position. The locking element prevents or reduces a thermal bridge through the opening, which could otherwise cause a drop in the interior temperature.

[0054] The locking element is preferably positively engaged in the insulating body and / or the wall, or can be inserted when the camera unit is in the parked position. This improves the thermal insulation at the opening.

[0055] It can be advantageous if the sealing element is made of the same insulating material or comprises the same insulating material as the insulating body.

[0056] It can be advantageous if the locking element is movably mounted on the holding unit and can be moved from a release position to a locked position and vice versa, whereby in the release position the passage opening is open and the camera unit can be moved into the inspection position. When the locking element assumes the release position, the camera unit can be moved through the passage opening into the inspection position, and vice versa. In the parked position of the camera unit, the locking element is positioned, or can be positioned, in the passage opening to close it.

[0057] As already described in connection with the explanation of the camera unit, it can be advantageous if the holding unit includes or forms at least one guide element for the slidable guidance of a movement of the shutter element, which can be guided directly or indirectly on the at least one guide element. 39524.

[0060] It can prove particularly advantageous if the control device includes a holding element to which the camera unit and the shutter element are attached, wherein the holding element is movably mounted on the holding unit and, in particular, rotatably mounted about a pivot axis. For example, the mounting is achieved via the aforementioned at least one corresponding guide element. Depending on the position of the holding element, the camera unit is preferably aligned with the through-opening, or the shutter element with the through-opening. By rotating the holding element, either the camera unit or the shutter element can be turned into a correct target position, from which the camera unit can be moved into the inspection position or the shutter element into the closed position. This allows for a structurally simple design of the control device while ensuring reliable operation.Separate mechanisms for moving the camera unit on the one hand and the shutter element on the other can be eliminated.

[0061] The control device preferably comprises a controllable adjustment unit coupled to the holding part, allowing the holding part to be moved and, in particular, pivoted about the axis of rotation. In a preferred embodiment, the adjustment unit can, for example, be electrically designed and include a lifting spindle drive. Alternatively, a pneumatic or hydraulic design is conceivable, wherein the adjustment unit comprises a piston-cylinder assembly.

[0062] The adjustment unit can, for example, engage the holding part eccentrically to the axis of rotation. In this configuration, the holding part can be rotated around the axis of rotation by a change in the length of the adjustment unit.

[0063] A rotation angle for the rotation of the camera unit or the shutter element in this position may, for example, be 90° or substantially 90°.

[0064] As already described in connection with the control of the camera unit, the control device may preferably comprise at least one of the following: an operating unit for actuating the adjustment unit; a data processing unit, wherein the adjustment unit can be actuated depending on the executable control program; 39524.

[0066] - 9 - an operating unit for the user and / or a data processing unit with a control program to act on the drive unit in order to move the locking element from the locked position to the released position.

[0067] As mentioned at the outset, the present invention also relates to a processing device.

[0068] A processing device for pharmaceutical containers according to the invention comprises a wall, an interior space at least partially enclosed by the wall, and a control device of the type described above.

[0069] The advantages mentioned in connection with the explanation of the control device according to the invention can also be achieved by means of the processing device. Advantageous embodiments of the processing device result from advantageous embodiments of the control device. Reference is made to the preceding explanations in each case.

[0070] The processing equipment can, for example, be a sterilization tunnel in which the pharmaceutical containers can be sterilized, with the control device being located, in particular, at a sterilization zone of the sterilization tunnel.

[0071] The wall could, for example, be a side wall of the sterilization tunnel.

[0072] Preferably, the control device is arranged on the inlet side of the sterilization zone.

[0073] Advantageously, the control device is located at the top of the sterilization zone, relative to a vertical direction, so as not to interfere with the transport of containers below.

[0074] By positioning the unit at the entrance to the sterilization zone, a large number or the entire number of containers downstream of the camera unit can preferably be captured within its field of view.

[0075] The cover element is advantageously positioned off-center within the interior, relative to a longitudinal center plane of the processing equipment. This off-center positioning on the wall minimizes the obstruction of downward airflow within the processing equipment, such as that found in a sterilization tunnel. 39524. BUS. P110PC

[0077] - 10 -

[0078] The camera unit's field of view is advantageously directed towards a conveyor belt and / or towards a longitudinal median plane of the processing equipment in order to capture as many containers as possible.

[0079] As mentioned at the outset, the present invention also relates to a method. A method according to the invention for operating a processing device of the type described above comprises:

[0080] Sterilizing the interior of the processing equipment, including a surface of the cover element of the control device, when the camera unit is located outside the interior and in particular is in the parked position; moving the camera unit into a control position in which the camera unit engages at least partially with the cover element; taking at least one picture of the interior using the camera unit; and moving the camera unit from the control position to the parked position.

[0081] The advantages already mentioned in connection with the explanation of the control device and the processing device according to the invention can be achieved by carrying out the method. Advantageous embodiments will become apparent from the preceding explanations, to which reference is hereby made.

[0082] The following description of preferred embodiments of the invention, in conjunction with the drawing, serves to further explain the invention. The processing device described can be used to carry out the method according to the invention in a preferred embodiment.

[0097] Figure 1 shows a schematic side view of an advantageous embodiment of the processing device according to the invention, designated by reference numeral 100. The processing device 100 is intended for processing pharmaceutical containers, which are not shown in the drawing, and can, for example, be part of a system for processing the containers.

[0098] In the present embodiment, the processing unit 100 is a sterilization tunnel 102, to which the containers can be fed via a feed device 104. The containers can be transported through the sterilization tunnel 102 and sterilized in a working direction 106. Further processing stations of the system can be arranged at the outlet of the sterilization tunnel 102. A weighing station 108, a filling station 110, and a closing station 112 are shown schematically.

[0099] The containers to be sterilized are, for example, vials, which are fed in bulk. The sterilization tunnel 102 includes a conveyor belt 114 on which the containers are transported either standing upright or positioned on a suitable frame or the like in the working direction 106. 39524. BUS. P110PC

[0100] October 13, 2025

[0101] - 12 -

[0102] The sterilization tunnel 102 comprises, with respect to the working direction 106, a heating zone 116, a sterilization zone 118 and a cooling zone 120. During operation, the containers are preheated in the heating zone 116, sterilized in the sterilization zone 118 and then cooled in the cooling zone 120 before being processed at one of the further processing stations.

[0103] The operation of the sterilization tunnel 102 is prepared by pre-sterilizing an interior space 122 of the sterilization zone 118 by heating it to a high temperature of 300 °C or higher (for example, 320 °C to 340 °C). During the transport of the containers, the temperature within the sterilization zone 118 can be the same or lower.

[0104] The sterilization tunnel 102 comprises a housing 124, which has a wall 126 enclosing the interior 122. The wall 126 is shown only schematically in Figures 2 to 8 and includes, in particular, a side wall 128 that laterally delimits the interior 122, transversely to the working direction 106.

[0105] A passage opening 130 is formed in the side wall 128.

[0106] The side wall 128 has a first side 132 facing the interior 122, and a second side 134 facing away from the interior 122 and accordingly pointing outwards.

[0107] An insulating body 136 is arranged on the second side 134. The insulating body 136 rests flat against the wall 126 and is thermally insulating to minimize heat loss from the housing 124. The wall 126 can preferably be completely covered with corresponding insulating bodies 136 or with a single insulating body 136 to provide advantageous insulating properties. In this case, the insulating body(s) 136 can, for example, extend along the entire length of the wall 126. For the purpose of explaining the present invention in a preferred embodiment, the design of the insulating body 136 as shown in the drawing is sufficient.

[0108] It is understood that the insulating body 136 is made of a thermal insulation material. 39524. BUS. P110PC

[0109] October 13, 2025

[0110] - 13 -

[0111] In the insulating body 136, a through-opening 138 is formed, which is aligned with the through-opening 130. In the present case, the cross-sectional area of ​​the through-opening 130 is larger than the cross-sectional area of ​​the through-opening 138. Both through-openings 130, 138 are preferably of a circular cross-section (Figure 8).

[0112] The processing device 100 comprises a preferred embodiment of the control device according to the invention, which is characterized by reference numeral 140. The insulating body 136 can be part of the control device 140.

[0113] The control device 140 comprises a holding unit 142, which is arranged on the second side 134. In this case, the holding unit 142 forms a frame 144 made of interconnected structural elements 146. The frame 144 is essentially cuboid in section (Figure 3), adjacent to the wall 126. Preferably, the cuboid section of the frame 144 is fixed to the wall 126. The connection is preferably thermally stable, for example by bolting or welding.

[0114] In this case, the frame 144 extends through the insulating body 136 (Figures 2 and 8). For this purpose, the insulating body 136 can, for example, be made of several individual components that are placed over the frame 144.

[0115] Furthermore, in the present embodiment, the holding unit 142 comprises two profile elements 148 projecting away from the frame 144 and from the wall 126. The profile elements 148 extend in a straight line and each form a guide element 150.

[0116] The holding unit 142 comprises a guide element 152 corresponding to the guide elements 150. The guide element 152 is designed as a running body 154. The running body 154 can be moved back and forth along the guide elements 150 by means of a drive unit to which it is coupled. The running body 154 can assume a position close to the wall (Figure 2) or a position farther from the wall (Figure 3). It is understood that intermediate positions are possible.

[0117] The drive unit 156 is, for example, a lifting spindle motor which can be fixed to the frame 144 via a retaining element 158 ​​(Figure 3).

[0118] The control device 140 comprises an operating unit 160 and a

[0119] Data processing unit 162, which further comprises a data storage unit 164 (Figure 2). 39524. BUS. P110PC

[0120] October 13, 2025

[0121] - 14 -

[0122] Units 160 and 162 can simultaneously be an operating unit or data processing unit of the processing facility 100.

[0123] For example, a user can manually actuate the drive unit 156 via the control unit 160.

[0124] Alternatively or additionally, the drive unit 156 is actuated automatically by the data processing unit 162 on the basis of an executable control program, which is stored, for example, in the data storage unit 164.

[0125] A retaining part 166 is fixed to the running body 154. The retaining part 166 is arranged between spaced-apart legs 168 of the running body and has a central opening 170 (Figure 3).

[0126] The retaining element 166 is rotatably mounted in the running body 154 about a pivot axis 172. In this case, the pivot axis 172 runs transversely and, in particular, perpendicular to the direction of movement of the running body along the guide elements 150, which are marked with reference numeral 174.

[0127] An actuating element 176 is arranged on the holding part 166. An adjusting unit 178 of the control device 140 engages the actuating element 176 eccentrically to the axis of rotation 172.

[0128] The adjustment unit 178 comprises an electric drive 180. The drive 180 engages a retaining element 182 (Figure 3) on the side facing away from the actuating element 176. This retaining element can, for example, be fixed to the frame 144. The drive 180 is, for example, a lifting spindle drive. The movement of the electric drive 180 can be easily and precisely controlled for accurate adjustment.

[0129] As a result of a change in length of the drive 180, the holding part 166 pivots about the axis of rotation 172. The angle of rotation is in particular 90° or substantially 90°.

[0130] In the present case, as will be discussed below, the retaining part 166 is rotated, particularly in the retracted position of the running body 154, away from the wall.

[0131] Instead of the electric drive 180, a pneumatic drive with a piston-cylinder unit can be provided, for example (not shown separately). The piston 39524. BUS. P110PC

[0132] October 13, 2025

[0133] - 15 -

[0134] In this case, the cylinder assembly can be actuated by a pressure unit 184 (Figure 3).

[0135] The drive 180 (or, if present, the pressure unit 184) is coupled to the control unit 160 and / or the data processing unit 162. This allows the user to manually operate the drive 180 at the control unit 160. Alternatively or additionally, automated operation via the data processing unit 162 is possible. In both cases, the holding element 166 is rotated about the axis of rotation 172 as desired.

[0136] The control device 140 comprises a camera unit 186. The camera unit 186 is held on the retaining part 166 and extends through the opening 170 with a camera housing 188. In this case, the housing 188 is essentially cylindrical, in particular circular-cylindrical, and has an elongated extension.

[0137] The camera unit 186 is shown schematically in the drawing only.

[0138] At the end of the camera unit 186, a window 190 is arranged, which may be part of a lens 192. A surface normal 194 of the window 190 has an angle of more than 90° with respect to a principal axis 196 of the camera unit 186 (Figure 8), the angle being measured from the end of the camera housing 188 opposite the window 190.

[0139] The camera unit 186 includes a cooling unit 198 (Figure 3). The cooling unit 198 is, for example, arranged in the camera housing 188. Fluid cooling is provided, in particular by means of compressed air. The cooling unit 198 is controllable and can be actuated, for example, by the data processing unit 162 and / or by the operating unit 160. The corresponding control lines for the camera unit 186 are not shown in the drawing.

[0140] The control device 140 further comprises a sleeve 200. The sleeve 200 engages the insulating body 136 from the side facing away from the wall 126 and preferably rests against it via a flange 202. The sleeve 200 is dimensioned such that it is positively engaged in the through-opening 138. As can be seen particularly from Figure 8, the through-opening 138 has a reduction in cross-section at the end of the sleeve 200. At the corresponding position, the control device 140 comprises an annular aperture 204, which is abutted against the sleeve 200. 39524. BUS. P110PC

[0143] A retaining ring 206 can rest against the wall 126, surrounding the camera housing 188.

[0144] The control device 140 further comprises a closure element 208. The closure element 208 is made of the same insulating material as the insulating body 136 and is designed in this case as a plug.

[0145] The shutter element 208 has a head section 210 and a plug section 212, the diameter of which is smaller than the diameter of the head section 210. The shutter element 208 is fixed to the retaining part 166 at the head section 210 by means of a retaining element 214. A principal axis 216 of the shutter element 208 is oriented perpendicular to the principal axis 196. Consequently, the camera unit 186 and the shutter element 208 are held on two sides of the retaining part 166 and are aligned at an angle of 90° to each other in their respective extensions.

[0146] The locking element 208 is dimensioned at the plug section 212 such that it can be inserted into the sleeve 200 in a form-fitting manner. When this is the case, the head section 210 rests flat against the flange 202.

[0147] The control device 140 further comprises a cover element 218. The cover element 218 is arranged on the first side 132 of the wall 126. As can be seen particularly from Figure 8, the cover element 218 is cap-shaped and forms a sleeve 220. The sleeve 220 is closed at one end facing the interior 122. At the opposite end, the sleeve 220 is open.

[0148] The sleeve 220 passes through the through-opening 130 and engages in the through-opening 138.

[0149] The sleeve 220 extends through the reduced cross-sectional section of the through-hole 138 and projects beyond the aperture 204, so that it engages into the sleeve 200.

[0150] By means of the sleeves 200, 220 and the aperture 204 a blind hole-like recess 222 is formed for the camera unit 186.

[0151] The cover element 218 is positioned close to the wall 126 and projects only a relatively small amount into the interior 122. In particular, the cover element 218 is positioned off-center with respect to a longitudinal median plane of the sterilization tunnel 102. (See 39524. BUS. P110PC.)

[0152] October 13, 2025

[0153] - 17 -

[0154] In this way, the airflow that can be generated by the blower 224 in the sterilization zone 118 is not or only insignificantly affected by the cover element 218.

[0155] Furthermore, the control device and thus the cover element 218 is located on the inlet side, with respect to the working direction 106, in the sterilization zone 118.

[0156] As can be seen particularly from Figure 8, the sleeve 220 is fixed to the wall 126. For this purpose, a flange 226 is provided, which is connected to the wall 126 from the side facing away from the interior 122. The connection is preferably thermally stable, for example by bolting or welding.

[0157] The flange 226 also forms a sealing unit 228. A gas-tight connection between the sleeve 220 and the wall 126 can be made via the sealing unit 228.

[0158] The cover element 218 is made of a pharmaceutical-grade material, in particular a metal such as stainless steel. However, to allow recordings by the camera unit 186, the cover element 218 has an optical window 230. The window 230 is secured to an opening 234 of the cover element 218 by a retaining frame 232, in this case by screws. The window 230 is sealed relative to the retaining frame 232 by sealing elements 236.

[0159] Window 230, for example, is made of borosilicate glass and is transparent in the IR range and / or the optical spectral range.

[0160] A surface normal 238 of the window 230 points downwards in the direction of the conveyor belt 114.

[0161] When the camera unit 186 assumes a control position, a field of view 240 is directed downwards through the window 230 towards the conveyor belt 114. Furthermore, the field of view is directed towards the longitudinal median plane of the sterilization zone 118, so that the camera unit 186 can capture as large an area as possible of the interior 122.

[0162] The camera unit 186 is primarily active in the visible spectrum. Alternatively or additionally, the camera unit 186 can, for example, be active in the IR (infrared) range. 39524. BUS. P110PC

[0163] October 13, 2025

[0164] - 18 -

[0165] During operation of the sterilization tunnel 102, the sterilization zone 118 is first heated to a high temperature, for example 320 °C, to sterilize the interior 122, including the components contained therein, and the inner wall 126. To protect the camera unit 186, it assumes a parked position as shown in Figure 7 at this time. In the parked position, the camera unit 186 is located outside the interior 122 and is situated on the second side 134. The retaining element 166 is rotated so that the camera unit 186 is turned out of alignment with the passage openings 130, 138. In this example, the window 190 points downwards. However, the rotation could also be in the opposite direction.

[0166] During the sterilization process of the interior 122, the closing element 208 assumes a closed position (Figure 7). The roller body 154 is pushed forward by the drive unit 156 so far that the closing element 208 closes the through-opening 138.

[0167] During the sterilization process, the side of the cover element 218 facing the interior 122 is also sterilized. The gas-tight connection relative to the wall 126 ensures that no particles enter the interior 122.

[0168] During the subsequent sterilization of the containers transported through the sterilization tunnel 102, the locking element 208 can remain in the closed position and the camera unit 186 in the parked position.

[0169] To monitor the process inside the interior 122, the camera unit 186 can be moved into a monitoring position and the shutter element 208 into a release position. For this purpose, the carriage 154 is first moved away from the wall 126 in the displacement direction 174. This releases the through-opening 138, and the shutter element 208 assumes an intermediate position (Figure 6). Subsequently, the retaining part 166 is rotated by means of the adjustment unit 178 so that the camera unit 186, in an intermediate position, has the desired target position, in which it is aligned with the through-openings 130, 138 (Figure 5). The camera unit 186 is then moved by means of the drive unit 156 toward the interior 122 until the leading end protrudes into the cover element 218 (Figures 2, 4, 8) and the camera unit 186 assumes the monitoring position. The locking element 208 assumes the release position.

[0170] Figure 3 shows the control device 140 during the rotation of the holding part 166. 39524. BUS. P110PC

[0171] October 13, 2025

[0172] - 19 -

[0173] When the camera unit 186 assumes the control position, recordings of the interior 122 can be made. The field of view 240 points through the window 190 into the interior 122.

[0174] The recordings can be displayed to a user on a display unit 242 (Figure 2). Preferably, the recordings can be stored in the data storage 164. In particular, storage in a data record relating to the batch of processed containers is conceivable.

[0175] At least when the camera unit 186 is in the control position, the cooling unit 198 is active to prevent the camera unit 186 from overheating. After the images have been taken, the camera unit 186 can be moved to the park position. For this purpose, the drive unit 154 is moved by means of the drive unit 156 (Figure 5). Subsequently, the retaining part 166 is rotated by means of the adjustment unit 178 (Figures 3 and 6) until the shutter element 208 returns to its target position and is aligned with the through-opening 138. To prevent a temperature drop in the interior 122, the shutter element 208 is then moved back to the closed position (Figure 7).
