Description

Technical Field

[0001] This invention relates to can cleaners, particularly track-mounted cleaners, for cleaning cans. The can cleaner includes: a static body having a housing having an upper housing portion and a lower housing portion configured for connection to a supply line for receiving cleaning fluid; a rotating body rotatable about a main rotation axis and mounted on the static body; a gear assembly including a gear assembly having a main input shaft and a main output shaft, the main output shaft extending beyond the housing and configured to drive the rotating body about the main rotation axis; and a nozzle carrier rotatable about a secondary rotation axis and mounted to the rotating body, the nozzle carrier having a secondary output shaft extending along the direction of the secondary rotation axis and driven by the main output shaft, and at least one nozzle for dispensing cleaning fluid, the secondary rotation axis being different from the main rotation axis. Background Technology

[0002] In the field of can cleaning, particularly in industrial and commercial environments, can cleaners that utilize rotary nozzles to deliver high-pressure cleaning fluids are commonly used. These devices are essential for maintaining the hygiene and operational efficiency of cans used to store a variety of substances, including food products, chemicals, and pharmaceuticals. Known systems typically involve a combination of static and rotating components driven by fluid pressure to achieve the desired cleaning effect. The rotary nozzles are usually powered by geared devices that convert fluid pressure into rotational motion.

[0003] According to known methods, tank cleaners typically consist of a static body connected to a supply line for receiving cleaning fluid and a rotating body housing a nozzle. DE 10 2019 005 830 A1 illustrates such a tank cleaner. The rotating body is driven by a gear assembly that converts fluid pressure into rotational motion. However, these systems often suffer from problems such as complex assembly and disassembly processes, which can lead to increased downtime and maintenance costs. During assembly, undesirable loads, such as torque, are applied to the components. This is particularly challenging for threaded connections. Additionally, the alignment and engagement of various components within the gear assembly can be challenging, for example, due to high water pressure and pressure drop, resulting in poor performance and potential mechanical failure. The need for precise alignment and secure engagement of the rotating and static parts is critical to ensuring consistent and effective cleaning.

[0004] Despite substantial progress in can cleaning technology, improvements are still needed to address these challenges. Existing systems may not provide the desired resistance to pressure drops within the rotating body. Furthermore, the complexity of current designs can lead to increased operating costs and reduced efficiency, highlighting the need for a more robust and user-friendly solution.

[0005] Therefore, the technical problem of the present invention is to provide a tank cleaner that at least partially overcomes the shortcomings of known systems. Summary of the Invention

[0006] The object of the present invention is to provide a can cleaner that overcomes one or more of the disadvantages of known systems.

[0007] According to a first aspect of the invention, these objectives are achieved by a tank cleaner according to the first main aspect.

[0008] The can cleaner includes a static body configured for connection to a supply line for receiving cleaning fluid, ensuring a stable and controlled flow of the cleaning medium. A rotating body mounted on the static body is driven to rotate about a main axis of rotation by a gear assembly at least partially housed within the static body. This gear assembly includes a main input shaft and a main output shaft, both extending along the direction of the main axis of rotation. The main output shaft drives the rotating body, facilitating consistent and powerful rotation necessary for effective cleaning. A nozzle carrier mounted to the rotating body rotates about a secondary axis of rotation, distinct from the main axis of rotation. This nozzle carrier includes a secondary output shaft driven by the main output shaft and is equipped with at least one nozzle for dispensing the cleaning fluid. The difference between the main and secondary axes of rotation allows for more comprehensive coverage of the can's inner surface, addressing the challenge of reaching all areas within the can.

[0009] This invention addresses the initially stated objective by proposing a main output shaft with a distal end extending along the main rotation axis beyond the auxiliary output shaft. This specific arrangement helps to better withstand pressure drops within the rotating body by reducing internal torsional forces and supports force distribution along the main output shaft, which extends longer than prior art output shafts. Furthermore, the auxiliary output shaft of the nozzle carrier also extends through the rotating body, ensuring well-balanced bearings for the nozzle carrier. Specifically, the auxiliary output shaft extends almost entirely through the rotating body, and therefore extends through at least 75% of its extension in the direction of the auxiliary rotation axis. Both the extension of the auxiliary output shaft and the extension of the main output shaft are beneficial during the assembly of the tank cleaner, as they improve shaft alignment and provide more design freedom for the bearings. Furthermore, proposing that the main output shaft extends beyond the auxiliary output shaft increases design freedom regarding possible coupling mechanisms. The technical configuration of the gear assembly and the relative positioning of the shafts can provide more efficient transmission of rotational forces and reduced torsional forces, thereby enhancing the overall performance and reliability of the tank cleaner.

[0010] Other embodiments of the invention are given in the appendices, which further develop the concept of the invention in the context of the object of the invention with respect to advantageous features and additional advantages.

[0011] According to a second aspect, which is also a preferred embodiment of the first aspect, the initially mentioned objective is achieved by a can cleaner according to the second main aspect. The invention addresses the initially mentioned objective according to the second aspect, wherein the main output shaft, particularly its distal end, is form-fitted with the rotating body. This ensures, in particular, a safe and precise transmission of rotary motion from the gear assembly to the rotating body. Form-fitting engagement means that the distal end of the main output shaft is designed to interlock or engage with a corresponding structure on the rotating body, thereby preventing any relative movement between these components during operation. This engagement can be achieved through various mechanical configurations such as splines, keys, or other interlocking geometries that provide form-fitting connections. The introduction of this feature brings several advantages to the can cleaner. First, it enhances the structural integrity and reliability of the rotary drive mechanism, ensuring that the rotating body is driven consistently and accurately by the main output shaft. This is particularly important in maintaining the efficiency and effectiveness of the cleaning process, as any slippage or misalignment can lead to poor cleaning performance. Second, form-fitting engagement reduces wear and breakage on components because the form-fitting connection minimizes relative movement that could lead to wear and deterioration over time. This contributes to the lifespan and durability of the can cleaner, thereby reducing maintenance requirements and downtime. Furthermore, existing can cleaners use threaded connections to secure the upper static body to the lower rotating body, and then use auxiliary methods to secure the can cleaner. Therefore, the proposed form-fit connection simplifies the assembly, as it provides a simple and reliable means of connecting the main output shaft to the rotating body. The form-fit connection replaces the threaded connection and preferably also the auxiliary methods. In particular, the auxiliary methods can also be implemented using a form-fit connection. Therefore, the form-fit connection allows the output shaft to be connected to the rotating body without any torque acting on the components during assembly. This is a particular benefit compared to threaded connections. Moreover, the form-fit connection allows for reduced assembly time compared to threaded connections. Furthermore, the precise alignment ensured by the form-fit connection enhances the overall balance and stability of the rotating body, thereby reducing vibration and noise during operation. This not only improves the user experience but also minimizes the risk of damage to the can or the cleaner itself.

[0012] According to another embodiment, the main output shaft engages with the auxiliary output shaft, particularly through a form-fit engagement. This engagement mechanism is achieved by the main output shaft extending beyond the auxiliary output shaft and represents a direct and precise interaction between the main and auxiliary output shafts, ensuring reliable transmission of rotational motion from the main axis of rotation to the auxiliary axis of rotation. The form-fit engagement indicates that the components are designed to interlock in a specific manner, potentially through complementary shapes such as splines, gears, or other interlocking structures, preventing slippage and ensuring synchronized movement. This precise engagement mechanism enhances the operational efficiency of the tank cleaner by maintaining consistent and controlled rotation of the nozzle carrier, which is crucial for effective cleaning. The form-fit engagement also implies a robust mechanical connection that can withstand the operational stresses and forces encountered during the cleaning process, thereby improving the durability and lifespan of the device. Furthermore, this engagement mechanism facilitates accurate alignment of the auxiliary and main output shafts, ensuring smooth and uniform rotation of the nozzle carrier about the auxiliary axis of rotation. This uniform rotation is necessary for the even distribution of the cleaning fluid dispensed through the nozzle, thereby optimizing cleaning performance. In addition, the shape-fitting engagement mechanism simplifies the assembly and maintenance of the tank cleaner, as the interlocking parts can be easily aligned and secured.

[0013] According to another embodiment, the auxiliary output shaft engages with both the nozzle carrier and the gear body of the gear assembly. The engagement mechanism between the auxiliary output shaft and the nozzle carrier may involve a mechanical connection such as a keyed connection or spline, ensuring that rotational motion is effectively transmitted without slippage. This engagement allows direct torque transmission from the gear body of the gear assembly via the auxiliary output shaft to the nozzle carrier, which connects both. The gear body is mounted to the rotating body and engages with the main output shaft to convert the torque of the main output shaft into rotation of the auxiliary output shaft. This conversion mechanism is necessary for the proper functioning of the tank cleaner because it ensures that the rotational motion generated by the main output shaft is effectively transmitted to the auxiliary output shaft, thereby driving the nozzle carrier. Furthermore, this engagement allows for a reduction in additional bearings and complex connection mechanisms. The new features introduced by this embodiment bring several advantages to the tank cleaner. First, the engagement of the auxiliary output shaft with both the nozzle carrier and the gear body ensures direct and efficient transmission of rotational motion, thereby reducing potential losses and enhancing the overall performance of the cleaning process. Secondly, the mounting of the gear body to the rotating body ensures the stability and alignment of the gear assembly, thereby reducing wear and breakage on components and extending the service life of the can cleaner. Finally, the torque conversion from the main output shaft to the auxiliary output shaft via the gear body allows for precise control of rotational speed and torque, enabling the nozzle carrier to operate effectively under various cleaning conditions. These features collectively enhance the functionality, reliability, and efficiency of the can cleaner, making it a more effective tool for cleaning cans. The auxiliary output shaft preferably extends through the nozzle carrier.

[0014] According to another embodiment, the secondary output shaft is supported on the rotating body through direct engagement with both the nozzle carrier and the gear body. Direct engagement means that the secondary output shaft is mechanically connected to the nozzle carrier and the gear body without intermediate components, which reduces mechanical complexity and potential points of failure.

[0015] According to another embodiment, the rotating body has a support structure for holding the main output shaft in a locked position. This support structure serves as a crucial intermediate component, ensuring the main output shaft is securely held in place during the assembly and operation of the tank cleaner. The presence of this support structure mitigates the risk of misalignment or displacement of the main output shaft, which could otherwise lead to operational inefficiency or mechanical failure. Furthermore, the main output shaft is form-fitted into a locked position by a locking element. This form-fit locking mechanism involves precise interlocking of components, ensuring the main output shaft is securely held in the designated position without any possibility of accidental movement. The locking element is specifically designed to engage with the main output shaft in a manner that prevents axial or rotational displacement, thereby maintaining the correct alignment and orientation of the shaft relative to the main rotation axis. This form-fit locking mechanism provides an additional layer of security and stability, ensuring the main output shaft remains in the optimal position for driving the rotating body and nozzle carrier. Additionally, these features facilitate easier maintenance and repair of the tank cleaner, as the secure locking of the main output shaft simplifies the disassembly and reassembly process.

[0016] According to another embodiment, the secondary output shaft extends through the support structure. Therefore, the secondary output shaft is securely anchored and properly aligned within the entire assembly of the can cleaner. By extending through the support structure, the secondary output shaft gains additional stability and support, which is crucial for maintaining the precise rotational movement required for effective cleaning. This structural integration helps minimize wobbling or misalignment that might otherwise occur during can cleaner operation, thereby enhancing the reliability and efficiency of the cleaning process. Furthermore, the extension of the secondary output shaft through the support structure facilitates a more robust connection between the rotating body and the nozzle carrier, ensuring a smooth and consistent transmission of rotational force from the main output shaft to the secondary output shaft. The support structure itself acts as a stabilizing element, providing a robust base for the secondary output shaft and helping to distribute the mechanical loads generated during operation. Additionally, the integration of the secondary output shaft with the support structure simplifies the assembly and maintenance of the can cleaner, as it provides a clear and simple path for the secondary output shaft, thus reducing the complexity of the internal configuration.

[0017] According to another embodiment, the support structure includes at least one guide passage opening configured to guide the secondary output shaft through it. Thus, the secondary output shaft is precisely aligned and held in its intended path of rotation about its secondary rotation axis. The guide passage opening acts as a conduit through which the secondary output shaft extends, thereby providing a controlled and stable bearing for the movement of the secondary output shaft. By guiding the secondary output shaft through the guide passage, the support structure effectively minimizes any lateral or axial deviations that may occur during rotation, thereby enhancing the accuracy and consistency of the rotational movement of the nozzle carrier. This precise guiding mechanism is crucial for the optimal performance of the nozzle carrier responsible for distributing cleaning fluid.

[0018] According to another embodiment, the main output shaft has a guide recess corresponding to a guide passage opening and configured to guide a secondary output shaft through the guide recess. The guide recess serves as a channel or passage that facilitates the movement and alignment of the secondary output shaft as it extends through the main output shaft. This configuration ensures that the secondary output shaft is precisely guided relative to the main output shaft and held in its intended position, thereby enhancing the stability and accuracy of the rotational movement of the nozzle carrier. The introduction of the guide recess and the corresponding guide passage opening provides several advantages to the can cleaner. First, it improves the mechanical integrity and alignment of the rotating components, thereby reducing the likelihood of misalignment or mechanical failure during operation. Second, the guide recess and guide passage opening facilitate smoother and more controlled rotational movement of the nozzle carrier. Furthermore, the combination of the guide recess and guide passage opening contributes to the durability and lifespan of the can cleaner by minimizing wear and breakage on the rotating components. By providing a guide passage for the secondary output shaft, the system can reduce friction and mechanical stress on the shaft and associated components, thereby extending the service life of the shaft and associated components. This can lead to lower maintenance requirements and reduced downtime for tank cleaners, thereby further enhancing the cost-effectiveness and reliability of tank cleaners in industrial cleaning applications.

[0019] According to another embodiment, the support structure has at least one locking passage opening configured to receive a locking element in a locked position. The locking passage opening is designed to accommodate the locking element, thereby ensuring that when the locking element is in the locked position, it effectively secures the rotating body and the nozzle carrier, preventing accidental movement or disassembly. This configuration is particularly advantageous in maintaining the precise alignment and rotational integrity of the nozzle carrier and the rotating body, which is crucial for effective and thorough cleaning of the can. By incorporating this locking mechanism, the can cleaner ensures that the gear assembly and rotating components remain securely in place even under the high-pressure conditions typically encountered during cleaning operations. This increased stability not only improves the reliability and durability of the can cleaner but also enhances the safety of its operation by reducing the risk of mechanical failure or accidental disassembly. Furthermore, the locking passage opening provides a simple and effective means of maintenance and assembly, allowing for quick and secure locking and unlocking of components. This feature simplifies the process of servicing the can cleaner, making it easier to perform routine maintenance or replace parts without compromising the overall integrity of the device.

[0020] According to another embodiment, the main output shaft has a locking recess corresponding to a locking passage opening and configured to receive a locking element in a locked position. The locking recess on the main output shaft is precisely aligned with the locking passage opening, ensuring that the locking element can be securely received and held in the locked position. This configuration allows for a more reliable and robust connection between the rotating body and the static body, preventing accidental disassembly or misalignment during operation. The locking element, when engaged in the locking recess, effectively secures the main output shaft relative to the static body, thereby maintaining the desired orientation and rotational dynamics of the rotating body and nozzle carrier. This feature is particularly advantageous in high-pressure cleaning applications, where the stability and precision of rotating components are critical for achieving optimal cleaning performance. By incorporating the locking recess on the main output shaft, this design ensures that rotational forces and vibrations generated during the cleaning process do not compromise the structural integrity of the can cleaner. Furthermore, this locking mechanism simplifies the assembly and maintenance of the can cleaner, as it provides a simple and secure method for aligning and securing the main output shaft within the static body. In addition, the locking recess and corresponding passage opening are designed to accommodate various types of locking elements such as pins, bolts or other fasteners, thus providing flexibility in the selection of locking mechanisms based on specific application requirements.

[0021] According to another embodiment, the can cleaner, particularly a track-mounted cleaner, includes a fastening element configured to secure a locking element in a locked position. The fastening element acts as a fixing component, ensuring that the locking element remains in a fixed position when engaged, thereby preventing any accidental movement or disengagement during cleaning operations. By incorporating the fastening element, the can cleaner benefits from an added layer of security, which is necessary for operation in environments where vibration or hydrodynamics could potentially cause component displacement. The fastening element can be designed in various forms, such as rings, belts, clamps, bolts, or latches, each providing a robust solution for effectively securing the locking element. This feature not only enhances the mechanical integrity of the can cleaner but also contributes to its operational safety. Furthermore, this feature simplifies maintenance and inspection procedures, as the operator can easily verify the locked position of the components, ensuring the cleaner is always in optimal working condition.

[0022] According to another embodiment, the main output shaft is aligned in a locked position by a locking element such that the auxiliary output shaft of the nozzle carrier can pass through the guide passage opening. This alignment mechanism introduces a precise and reliable means of ensuring that the main output shaft and the auxiliary output shaft of the nozzle carrier are correctly positioned relative to each other, thereby facilitating smooth operation of the nozzle carrier. The locking element acts as a critical intermediary, ensuring that the main output shaft remains in the correct orientation, thus preventing any misalignment that could disrupt the rotational dynamics of the nozzle carrier. The guide passage opening acts as a conduit through which the auxiliary output shaft of the nozzle carrier can be accurately positioned, further contributing to the overall accuracy of the tank cleaner's operation. This arrangement not only simplifies the assembly and maintenance of the tank cleaner but also enhances the operational reliability of the tank cleaner by reducing the likelihood of mechanical failures due to misalignment.

[0023] According to another embodiment, the guide passage opening and the locking passage opening are aligned in parallel and arranged at a distance from each other in the direction of the main rotation axis. This feature also simplifies the assembly and maintenance process because the parallel and spaced arrangement of the openings provides clear reference points for the installation and alignment of components. Furthermore, by arranging the guide passage opening and the locking passage opening in parallel and by arranging them at a distance from each other, the guide passage opening and the locking passage opening do not interfere with each other, thereby improving accessibility.

[0024] According to another embodiment, locking recesses and / or guide recesses are provided at the distal end of the main output shaft. The locking recesses and / or guide recesses at the distal end of the main output shaft serve as precise engagement points, ensuring a secure and stable connection with the corresponding components, thereby preventing accidental disassembly or misalignment during operation. Furthermore, the arrangement of the locking recesses and / or guide recesses at the distal end of the main output shaft helps to better withstand pressure drop during operation due to improved force transmission. The presence of these recesses at the distal end of the main output shaft also allows for easier assembly and maintenance of the tank cleaner, as these recesses provide clear reference points for component alignment and positioning.

[0025] The invention addresses the initially mentioned objective in a third aspect by means of a gear assembly according to the third main aspect. The gear assembly is specifically designed for can cleaners, particularly for can cleaners according to the first or second aspect, and includes a main input shaft that serves specifically as a main conduit for transmitting mechanical energy from the supply line to the internal components of the cleaner. A main output shaft extends along the main axis of rotation, thereby ensuring efficient transmission of rotational energy to the rotating body, which in turn enables the rotating body to rotate about the main axis of rotation. Additionally, the main output shaft is configured to drive a secondary output shaft extending along a secondary axis of rotation. This secondary axis of rotation, distinct from the main axis of rotation, introduces auxiliary rotational motion that enhances the cleaning range and effectiveness of the can cleaner. The secondary output shaft drives a nozzle carrier that houses at least one nozzle for dispensing cleaning fluid. This dual-axis rotation mechanism ensures that the cleaning fluid is distributed comprehensively and in a controlled manner, reaching all areas within the can. Furthermore, the main output shaft is characterized by preferably extending along the main axis of rotation beyond the distal end of the secondary output shaft, or the main output shaft, particularly its distal end, is shaped to engage with the rotating body, thereby allowing rotational motion to be transmitted from the gear assembly to the rotating body. By combining these features, the gear assembly possesses the advantages described with respect to the first and second aspects of the invention. Therefore, the benefits and preferred embodiments of the first and second aspects of the invention are also the benefits and preferred embodiments of the third aspect of the invention.

[0026] The invention addresses the initially mentioned objective in a fourth aspect by a method for mounting a tank cleaner according to the fourth main aspect. The method for mounting the tank cleaner begins by connecting a static body to a supply line for receiving cleaning fluid, thereby establishing a fundamental connection that ensures a continuous and controlled flow of cleaning fluid into the system. Subsequently, a rotating body is mounted on the static body, allowing the rotating body to rotate about a main axis of rotation. This rotational capability is crucial for the dynamic operation of the tank cleaner, enabling it to reach various areas within the tank. A nozzle carrier is then mounted to the rotating body, allowing the nozzle carrier to rotate about a secondary axis of rotation different from the main axis. This dual-axis rotation enhances the cleaning range and flexibility of the tank cleaner, allowing it to target specific areas more effectively. The nozzle carrier is designed with a secondary output shaft extending through the rotating body along the secondary axis of rotation, facilitating precise delivery of cleaning fluid through the nozzle. A gear assembly is then arranged such that its main output shaft extends from the static body into the rotating body along the main axis of rotation. This configuration ensures that the rotating body is driven about the main axis of rotation, providing the necessary mechanical power for the operation of the rotating body. Furthermore, according to the first preferred design, the main output shaft is characterized by extending beyond the distal end of the auxiliary output shaft along the main rotation axis within the rotating body. Alternatively or additionally, the main output shaft, particularly the distal end of the main output shaft, engages with the shape of the rotating body. By combining these features, the method possesses the advantages described with respect to the first aspect of the invention. Therefore, the benefits and preferred embodiments of the first and second aspects of the invention are simultaneously the benefits and preferred embodiments of the fourth aspect of the invention.

[0027] According to another embodiment of the method, the main output shaft, including its distal end, engages with the rotating body in a shape-fitting manner, thereby ensuring a robust and precise connection that facilitates the efficient transmission of rotational force. This engagement mechanism is crucial for maintaining the alignment and stability of the rotating body during operation.

[0028] According to another embodiment of the method, the main output shaft and the auxiliary output shaft are engaged, particularly in a form-fit engagement. This is necessary for the coordinated rotation of the nozzle carrier about its auxiliary axis of rotation. This engagement ensures that the rotational motion from the main output shaft is accurately transmitted to the auxiliary output shaft, thereby enabling the nozzle carrier to effectively dispense cleaning fluid.

[0029] According to another embodiment of the method, the main output shaft is held in a locked position by a support structure of the rotating body, and is locked in that position by a locking element in a form-fitting manner. This locking mechanism provides additional stability and prevents any accidental movement or displacement of the main output shaft during operation, thereby enhancing the reliability of the tank cleaner.

[0030] According to another embodiment of the method, the secondary output shaft is guided through at least one guide passage opening in the support structure. This ensures that the secondary output shaft remains properly aligned and can rotate smoothly. The guiding mechanism is preferably supplemented by guiding the secondary output shaft through a guide recess on the main output shaft corresponding to the guide passage opening. This further ensures precise alignment and smooth operation.

[0031] According to another embodiment of the method, the secondary output shaft is guided through at least one locking passage opening of the support structure and through a locking recess of the primary output shaft corresponding to the locking passage opening. These guiding mechanisms collectively ensure that the secondary output shaft is securely positioned and can rotate without obstruction.

[0032] Finally, the locking element is preferably secured in the locked position by a fastening element, which provides an extra layer of security and ensures that the locking mechanism remains engaged during operation of the can cleaner. These features collectively enhance the structural integrity, operational reliability, and overall performance of the can cleaner, making it more effective in its intended application for cleaning cans.

The gear body 160 is preferably supported on the main output shaft 130 by a main output shaft bearing 98. This engagement converts the torque of the main output shaft 130 into rotation of the secondary output shaft 81. The secondary output shaft 81 is supported on the rotating body 4 through direct engagement with both the nozzle carrier 8 and the gear body 160.

[0053] The gear assembly 10 is at least partially arranged in the static body 3 and includes a gear body 160 mounted to the rotating body 4. The gear body 160 engages with the main output shaft 130 and converts the torque of the main output shaft 130 into rotation of the auxiliary output shaft 81, as per [reference to...]. Figure 1a and Figure 1b As described. The auxiliary output shaft 81 is supported on the rotating body 4 by direct engagement with the nozzle carrier 8 and the gear body 160, and thus extends through the nozzle carrier 8 and the rotating body 4.
