Description

Technical Field

[0001] The present invention relates to the processing of trolleys, particularly to a system for processing products loaded on trolleys by means such as sterilization and the packaging included therein.

Background Art

[0002] Retort food means food formed by heating sealed food and beverage products with high-temperature heat for sterilization and then rapidly cooling them. A retort sterilizer is a device that performs the operation of applying high-temperature heat to sealed products during the manufacturing process of such retort food.

[0003] In order to sterilize products uniformly and well and process a large number of products in a short time to increase the production efficiency of products, various methods have been applied.

[0004] A batch method can be used in which products are loaded on trolleys and enter a sterilizer, and all processing steps including sterilization are carried out simultaneously. In this case, there are problems such as low thermal efficiency, a need for additional heat treatment time, deviation in heat distribution, and non-uniform heating.

[0005] A continuous method can be used in which products are continuously transferred and each product is processed in an individual space one by one. In this case, there are problems such as the overall length of the device becoming excessively long, difficulty for operators to enter due to a complex structure, and difficulty in maintenance.

[0006] Furthermore, while systems have emerged to compensate for the disadvantages of continuous and batch sterilization methods, for safety reasons, the entire sterilization system must be designed to conform to the standards of a pressure vessel. In particular, in some countries, the entire sterilization system is treated similarly to a pressure vessel and can only be distributed when it meets the design requirements of a pressure vessel. Therefore, even if the disadvantages of continuous and batch sterilization methods are compensated for, there was a problem in that the system deformation had to be carried out within a structure that could adequately maintain airtightness between each component in order to meet the design requirements of a pressure vessel. [Overview of the project] [Problems that the invention aims to solve]

[0007] This invention was developed to solve these problems and provides a trolley processing system and packing included therein that facilitates airtightness. [Means for solving the problem]

[0008] A packing according to an embodiment of the present invention includes an expansion portion which is inserted into an annular groove formed on the outer surface of an object to be installed and has an expansion space inside into which air can flow, and a sealing portion which is connected to the side surface of the expansion portion that faces outward from the groove and is provided to be pushed out of the groove as the expansion portion expands to pressurize the object to be pressed, in order to maintain airtightness at the boundary between the object to be installed and an adjacent pressurized object.

[0009] A trolley processing system according to an embodiment of the present invention includes a pre-processing module for processing trolleys, an intermediate module provided to receive and process trolleys processed by the pre-processing module, and a post-processing module provided to receive and process trolleys processed by the intermediate module, wherein the intermediate module includes an intermediate body, a front end flange formed at the front end of the intermediate body, a rear end flange formed at the rear end of the intermediate body, a pre-processing seal inserted into a groove formed in the rear end flange to maintain airtightness at the boundary between the pre-processing module and the intermediate module, and a post-processing seal which is a packing inserted into a groove formed in the front end flange to maintain airtightness at the boundary between the post-processing module and the intermediate module. [Effects of the Invention]

[0010] This allows for the use of a trolley system and enables the rapid and uniform heating of the loaded products.

[0011] By enabling module separation, maintenance of the sterilizer becomes easier, and if major repairs are needed, modules can be separated and replaced or repaired.

[0012] Even if a malfunction occurs in a specific module, causing a product defect, the problem will only affect that module and the products located within it, thus minimizing the amount of waste.

[0013] Despite having a structure in which the modules are separated, airtightness between each module can be easily maintained by the connection points. [Brief explanation of the drawing]

[0018] Figure 1 is a perspective view of the trolley processing system 1 according to one embodiment of the present invention. Figure 2 is a view of the trolley processing system 1 according to one embodiment of the present invention along the left-right direction. Figure 3 is a view of the trolley processing system 1 according to one embodiment of the present invention viewed from above and downwards.

[0019] Referring to the drawings, a trolley processing system 1 according to one embodiment of the present invention includes a pre-processing module 10, an intermediate module 20, and a post-processing module 30. The intermediate module 20 is provided to process trolleys C that have been processed by the pre-processing module 10. The post-processing module 30 is provided to process trolleys C that have been processed by the intermediate module 20. Each module is a module that applies processing such as heat treatment to products loaded on trolleys C, and can be called a trolley processing module. That is, the pre-processing module 10, the intermediate module 20, and the post-processing module 30 can be called trolley processing modules. However, the processing that each trolley processing module applies to trolleys C and the products loaded on trolleys C is not limited to heat treatment.

[0020] The modules constituting the trolley processing system 1 of the present invention can be arranged along the front-rear direction. The pre-processing module 10, intermediate module 20, and post-processing module 30 can be arranged in order facing forward. A trolley C can move forward within the trolley processing system 1. A trolley C processed in the pre-processing module 10 can move forward and be transmitted to the intermediate module 20 for further processing, and a trolley C processed in the intermediate module 20 can move forward and be transmitted to the post-processing module 30 for further processing.

[0021] In this specification, the left-right direction and the up-down direction mean directions perpendicular to the front-rear direction. Each direction is used for convenience of explanation and may be relative depending on the direction and orientation in which the trolley processing system 1 is positioned.

[0022] The pre-processing module 10 may include a pre-processing body 11. The intermediate module 20 may include an intermediate body 21, and the post-processing module 30 may include a post-processing body 31. The pre-processing body 11 can be defined as enclosing a pre-processing space, which is an internal space provided through which a trolley C can pass and be processed. The intermediate body 21 can be defined as enclosing an intermediate space, which is an internal space provided through which a trolley C can pass and be processed. The post-processing body 31 can be defined as enclosing a post-processing space, which is an internal space provided through which a trolley C can pass and be processed. Therefore, the pre-processing body 11, the intermediate body 21, and the post-processing body 31 can be physically separated from the external space. Each module may be referred to as a trolley processing module, and the pre-processing body 11, the intermediate body 21, and the post-processing body 31 may be referred to as processing bodies. The processing body may be formed in a cylindrical shape that is open along the front-rear direction, but its form is not limited thereto.

[0023] The intermediate module 20 may include a protruding body 217 that extends from the cylindrical portion of the intermediate body 21. The protruding body 217 may house a portion for providing driving force to the rotating means 24.

[0024] The processing body includes a rigid processing body divided into multiple parts and a flexible processing body made of an expandable or expandable material that connects the divided parts of the rigid processing body, thereby forming an expansion joint. Each part of the rigid processing body can be divided from one another along the front-to-back direction, and the flexible processing body can connect each of these rigid processing body parts 211 in the front-to-back direction.

[0025] By including a soft treatment body, the treatment body can expand or contract in the front-rear direction due to external forces applied to the treatment body, such as pressure differences. When contracted, the soft treatment body may have a wrinkled shape. In one embodiment of the present invention, the intermediate body 21 is described as being expandable or contractible by being divided into two parts of an intermediate hard treatment body 211, which is a type of hard treatment body, and an intermediate soft treatment body 214, which is a type of soft treatment body, but such a configuration is not limited to the intermediate body 21. The treatment body becomes elastic, and the treatment body can accommodate changes in pressure. By accommodating changes in pressure, when changes in pressure occur while the bodies 11, 21, and 31 of each module 10, 20, and 30 are connected to each other by connecting parts 13, 22, 23, and 33, damage to the connecting parts 13, 22, 23, and 33 due to changes in pressure can be prevented.

[0026] The processing body may further include bridges 215 that connect multiple parts of the hard processing body to prevent excessive deformation, such as distortion of the parts of the hard processing body that are separated from each other by the soft processing body.

[0027] The trolley processing module may include a heat transfer medium supply device formed toward the internal space for heat treatment of the trolley C. The heat transfer medium may be steam, hot water, a refrigerant, etc., and the heat transfer medium supply device may include a pump and nozzles for pressurizing the heat transfer medium. The trolley processing module may further include other medium supply devices that spray disinfectants for other treatments such as disinfection, or spray detergents or cleaning water for internal cleaning.

[0028] Figure 4 is a perspective view showing the intermediate module 20 of the trolley processing system 1 according to one embodiment of the present invention separated from the pre-processing module 10 and the post-processing module 30. Figure 5 is a view of the state in Figure 4 from above to below. Figure 6 is a view showing the state in Figure 4 with the shutters 16 and 36 closed.

[0029] Each module can be separated from or connected to one another. The intermediate module 20 can be configured to be in either a connected state, coupled to the pre-processing module 10 and the post-processing module 30, or a separated state, separated from the pre-processing module 10 and the post-processing module 30. When transitioning from the connected state to the separated state, the intermediate module 20 can detach from the pre-processing module 10 and the post-processing module 30 along a direction that crosses the front-to-back direction. Conversely, when transitioning from the separated state to the connected state, the intermediate module 20 can approach the pre-processing module 10 and the post-processing module 30 along a direction that crosses the front-to-back direction. In one embodiment of the present invention, the direction in which the intermediate module 20 detaches from the pre-processing module 10 and the post-processing module 30 while in the separated state is described as left, and the direction in which the intermediate module 20 moves while in the connected state is described as right, but the directions are not limited to these.

[0030] A trolley handling system 1 according to one embodiment of the present invention may include a module moving device 40. The module moving device 40 is coupled to an intermediate module 20 to move the intermediate module 20 so that it is placed in either a coupled state or a separated state. The module moving device 40 may include a moving rail 41 to which the intermediate module 20 is slidably coupled. The moving rail 41 may extend along the left-right direction and be placed on the ground. The intermediate module 20 may include intermediate legs 27 extending downward from the intermediate body 21 and intermediate rollers coupled to the lower ends of the intermediate legs 27 so that it can slide along such a moving rail 41, and the intermediate rollers may be slidably coupled to the moving rail 41. The module moving device 40 may include a fixed rail 42 extending along the front-rear direction, which is coupled to other modules so that other modules can be placed in a predetermined position. The moving rail 41 may be placed across the fixed rail 42.

[0031] The pre-processing module 10 has pre-processing legs 17 extending downward from the pre-processing body 11, and the post-processing module 30 has post-processing legs 37 extending downward from the post-processing body 31. The lower ends of the pre-processing legs 17 and post-processing legs 37 can be connected to a fixed rail 42 or positioned on the ground to support the pre-processing module 10 and the post-processing module 30, respectively.

[0032] A towing hook 216 can be formed on the outer surface of the intermediate body 21, to which a winch or hoist can be attached. By attaching a winch or hoist to the towing hook 216 and pulling along the left-right direction, the intermediate module 20 can move along the moving rail 41, separating from or joining the pre-processing module 10 and the post-processing module 30.

[0033] In addition, the module moving device 40 includes a power source and drives the intermediate rollers, allowing the intermediate module 20 to move left and right along the moving rail 41.

[0034] In this way, each trolley processing module can be selectively separated or combined to form an integrated system capable of processing trolley C in stages as it moves forward. This facilitates maintenance of the trolley processing system 1, and if major repairs are needed, the necessary trolley processing module can be separated and replaced or repaired.

[0035] Furthermore, even if a malfunction occurs in a specific cart processing module, resulting in product defects, the problem will only affect that cart processing module and the products located within it, thus minimizing the amount of product waste.

[0036]

[0037] door

[0038] Figure 7 is a perspective view showing the state in which the pre-processing door 50 of the trolley processing system 1 according to one embodiment of the present invention is open.

[0039] A system inlet can be formed at the rear end of the pre-processing body 11 of the pre-processing module 10, which is open in the front-rear direction. The trolley C can move forward through the system inlet and enter the interior of the trolley processing system 1 from the outside. The pre-processing module 10 may include an inlet coupling portion 12 installed at the rear end of the pre-processing body 11.

[0040] A trolley processing system 1 according to one embodiment of the present invention may include a pre-processing door 50. The pre-processing door 50 is a device for opening and closing the system entrance. The pre-processing door 50 may include a pre-processing door shielding portion 51. The pre-processing door shielding portion 51 is a portion positioned adjacent to the rear end of the pre-processing body 11 so as to shield the system entrance when opening and closing it. The system entrance may be formed in a circular shape, and the pre-processing door shielding portion 51 may also be formed in a circular shape. When viewed along the front-rear direction, the area of ​​the pre-processing door shielding portion 51 may be larger than the area of ​​the system entrance.

[0041] The pre-treatment door 50 may include a pre-treatment door support 53. The pre-treatment door support 53 is the part to which the pre-treatment door shielding 51 is coupled so as to be rotatable in the front-rear direction as an axial direction when the system entrance is opened and closed. The pre-treatment door support 53 can be coupled to the pre-treatment module 10, but is not fixed to the pre-treatment module 10; it may be fixed to the ground or to the fixed rail 42.

[0042] The pre-treatment door 50 may include a pre-treatment door coupling 52. The inlet coupling 12 and the pre-treatment door coupling 52 are coupled to a pre-treatment door flange 54 formed on the periphery of the pre-treatment door shielding 51, and the pre-treatment module 10 and the pre-treatment door 50 can be coupled when the pre-treatment door shielding 51 closes the system inlet. The operation of the pre-treatment door coupling 52 and the inlet coupling 12 will be explained in detail when describing the coupling relationship between the intermediate module 20, the pre-treatment module 10 and the post-treatment module 30, which will be described later.

[0043] A system outlet can be formed at the front end of the post-processing body 31 of the post-processing module 30, which is open in the longitudinal direction. The trolley C can move forward through the system outlet and be discharged from the inside to the outside of the trolley processing system 1. The post-processing module 30 may include an outlet coupling portion 32 installed at the front end of the post-processing body 31.

[0044] A trolley processing system 1 according to one embodiment of the present invention may include a post-processing door 60. The post-processing door 60 is a device for opening and closing the system exit. The post-processing door 60 may include a post-processing door shielding portion 61. The post-processing door shielding portion 61 is a portion positioned adjacent to the front end of the post-processing body 31 so as to shield the system exit when opening and closing it. The system exit may be formed in a circular shape, and the post-processing door shielding portion 61 may also be formed in a circular shape. When viewed along the front-rear direction, the area of ​​the post-processing door shielding portion 61 may be larger than the area of ​​the system exit.

[0045] The post-processing door 60 may include a post-processing door support 63. The post-processing door support 63 is the part to which the post-processing door shielding 61 is coupled so as to be rotatable in the front-rear direction when the system exit is opened and closed. The post-processing door support 63 can be coupled to the post-processing module 30, but is not fixed to the post-processing module 30; it may be fixed to the ground or to the fixed rail 42.

[0046] The post-processing door 60 may include a post-processing door coupling portion 62. The outlet coupling portion 32 and the post-processing door coupling portion 62 are coupled to the post-processing door flange formed on the periphery of the post-processing door shielding portion 61, and the post-processing module 30 and the post-processing door 60 can be coupled when the post-processing door shielding portion 61 closes the system outlet. The operation of the post-processing door coupling portion 62 and the outlet coupling portion 32 will be explained in detail when describing the coupling relationship between the intermediate module 20 and the pre-processing module 10 and post-processing module 30, which will be described later.

[0047] The pre-processing door 50 and the post-processing door 60 allow the trolley processing system 1 to form an entirely sealed internal space, and this internal space can be separated from the outside by the pre-processing door 50, the post-processing door 60 and each module.

[0048]

[0049] joint part

[0050] Figure 8 is a perspective view illustrating the situation in which the intermediate module 20 of the trolley processing system 1 according to one embodiment of the present invention approaches the pre-processing module 10 and the post-processing module 30. Figure 9 is an enlarged and detailed view of a portion of Figure 8. Figure 10 is a view of a portion of Figure 8 from above to below. Figure 11 is a diagram illustrating the region adjacent to the front end coupling portion 23 of the trolley processing system 1 according to one embodiment of the present invention.

[0051] The intermediate module 20 may include a front end coupling portion 23 that connects to the front end of the intermediate body 21. The intermediate module 20 may also include a rear end coupling portion 22 that connects to the rear end of the intermediate body 21. The pre-processing module 10 may include a pre-processing coupling portion 13 that connects to the rear end of the pre-processing body 11. The post-processing module 30 may include a post-processing coupling portion 33 that connects to the front end of the post-processing body 31.

[0052] In the coupled state, the pre-processing coupling section 13 and the rear-end coupling section 22 can connect the pre-processing main body 11 and the intermediate module 20. In the coupled state, the post-processing coupling section 33 and the front-end coupling section 23 can connect the post-processing main body 31 and the intermediate module 20. In other words, each coupling section can connect modules that are in contact with each other.

[0053] When transitioning from a separated state to a connected state, the intermediate module 20 moves along a first direction, which is one of the left-right directions, and the second direction is the opposite direction to the first direction. In one embodiment of the present invention, the first direction is described as being to the right and the second direction as being to the left.

[0054] The pre-processing coupling portion 13 can be located on the first direction side of the rear end of the pre-processing body 11, and the post-processing coupling portion 33 can be located on the first direction side of the rear end of the post-processing body 31. The front coupling portion 23 can be located on the second direction side of the front end of the intermediate body 21, and the rear coupling portion 22 can be located on the second direction side of the rear end of the intermediate body 21. With this coupling portion arrangement, collisions between each coupling portion can be prevented when the intermediate module 20 moves from a separated state to a coupled state.

[0055] The pre-processing coupling section 13 and the rear-end coupling section 22 surround the boundary between the pre-processing main body 11 and the intermediate main body 21, allowing the pre-processing module 10 and the intermediate module 20 to be coupled. The post-processing coupling section 33 and the front-end coupling section 23 surround the boundary between the post-processing main body 31 and the intermediate main body 21, allowing the intermediate module 20 and the post-processing module 30 to be coupled.

[0056] Specifically, the structure of the front end coupling portion 23 shown in Figure 11 will be described. The front end coupling portion 23 surrounds a part of the front end flange 213 that is formed to project radially outward from the periphery of the front end of the intermediate body 21 and is coupled to the front end flange 213, and in the coupled state, can be formed to surround a part of the post-processing flange 313 that is formed to project radially outward from the periphery of the rear end of the post-processing body 31. The front end coupling portion 23 can be coupled to the front end flange 213 by interlocking, by bonding via adhesive, or by using fasteners. The front end flange 213 and the post-processing flange 313 can be formed in an annular shape, and the front end coupling portion 23 can also have the shape of a part of the ring when viewed along the front-rear direction, and can have a shape like the periphery of a semicircle.

[0057] In the specification of this invention, "annular" is not limited to a round ring, but is a general term for any shape that forms a closed curve. Therefore, an annular shape can include a round ring shape, a rectangular periphery shape, a polygonal periphery shape, a polygonal periphery shape with rounded corners, and so on.

[0058] The front end coupling portion 23 has a "U" shaped cross-section and can surround the front end flange 213. The front end coupling portion 23 may include a front end coupling rear end member 231 that contacts the rear surface of the front end flange 213, a front end coupling intermediate member 232 that extends forward from the front end coupling rear end member 231 and contacts the peripheral edge surface of the front end flange 213, and a front end coupling front end member 233 that extends radially inward from the front end of the front end coupling intermediate member 232 and forms a front end coupling space 230 between it and the front surface of the front end flange 213, into which the post-processing flange 313 can be inserted together with the front end coupling intermediate member 232. In the coupled state, the front end flange 213 and the post-processing flange 313 are positioned in the space formed by the front end coupling portion 23 and surrounded by the front end coupling portion 23, thereby enabling the coupling of the intermediate module 20 and the post-processing module 30. A pressure hole 234 is formed in the front end coupling front end member 233, allowing fastening members such as bolts to be inserted to further pressurize the flange inserted inside.

[0059] The post-processing coupling portion 33 of the post-processing module 30 is identical to the front end coupling portion 23 described above, but can have opposite configurations in the front-rear direction, and similarly can surround and connect the front end flange 213 and the post-processing flange 313. Therefore, the front end coupling portion 23 and the post-processing coupling portion 33 can connect the intermediate module 20 and the post-processing module 30. When such a connection is made, the front end coupling portion 23 and the post-processing coupling portion 33 can come into contact to form a single ring so that airtightness is well maintained.

[0060] The pre-processing coupling portion 13 and the rear-end coupling portion 22 have configurations corresponding to the configurations of the front-end coupling portion 23 and the post-processing coupling portion 33 described above, allowing the pre-processing module 10 and the intermediate module 20 to be coupled by surrounding the pre-processing flange 113 and the rear-end flange 212. Therefore, the description of the pre-processing coupling portion 13 and the rear-end coupling portion 22 is the same as or similar to the description of the front-end coupling portion 23 and the post-processing coupling portion 33, and will be used accordingly. For example, the pre-processing flange 113 may also include a pre-processing coupling rear-end member, a pre-processing coupling intermediate member, a pre-processing coupling front-end member, etc.

[0061] The pre-processing door coupling portion 52 and the entrance coupling portion 12 have configurations corresponding to those of the front end coupling portion 23 and the post-processing coupling portion 33 described above, allowing the pre-processing door 50 and the pre-processing module 10 to be coupled by surrounding the pre-processing door flange 54 and the entrance flange 112. Therefore, the description of the pre-processing door coupling portion 52 and the entrance coupling portion 12 is the same as or similar to the description of the front end coupling portion 23 and the post-processing coupling portion 33, and will be applied accordingly.

[0062] The post-processing door coupling portion 62 and the exit coupling portion 32 have configurations corresponding to those of the front coupling portion 23 and the post-processing coupling portion 33 described above, allowing the post-processing door 60 and the post-processing module 30 to be coupled by surrounding the post-processing door flange and the exit flange 312. Therefore, the description of the post-processing door coupling portion 62 and the exit coupling portion 32 is the same as or similar to the description of the front coupling portion 23 and the post-processing coupling portion 33, and will be applied accordingly.

[0064] Packing 70

[0065] Figure 12 shows the arrangement of the pre-processing seal 251 in the intermediate module 20 of the trolley processing system 1 according to one embodiment of the present invention. Figure 13 shows the arrangement of the entrance seal 151 in the pre-processing module 10 of the trolley processing system 1 according to one embodiment of the present invention. Figure 14 shows the arrangement of the exit seal 351 in the post-processing module 30 of the trolley processing system 1 according to one embodiment of the present invention. Figure 15 shows the arrangement of the post-processing shutter seal 352 placed in the post-processing shutter 36 of the trolley processing system 1 according to one embodiment of the present invention.

[0066] A trolley processing system 1 according to one embodiment of the present invention may include packing 70. The packing 70 is positioned at the boundary between components to maintain airtightness at the boundary.

[0067] Referring to the drawings, the intermediate module 20 may include a post-processing seal, which is an annular packing 70 inserted into a groove formed in the front flange 213, to maintain airtightness at the boundary between the intermediate body 21 and the post-processing module 30. The intermediate module 20 may also include a pre-processing seal 251, which is an annular packing 70 inserted into a groove formed in the rear flange 212, to maintain airtightness at the boundary between the intermediate body 21 and the pre-processing module 10.

[0068] The pre-treatment module 10 may include an inlet seal 151, which is a packing 70 inserted into a groove formed in the inlet flange 112, to maintain airtightness at the boundary between the pre-treatment module 10 and the pre-treatment door 50. The post-treatment module 30 may include an outlet seal 351, which is a packing 70 inserted into a groove formed in the outlet flange 312, to maintain airtightness at the boundary between the post-treatment module 30 and the post-treatment door 60.

[0069] The pre-processing module 10 may include a pre-processing shutter 16. The pre-processing shutter 16 may include a pre-processing shutter shielding portion, a pre-processing shutter housing in which a pre-processing opening is formed that is selectively shielded and opened by the pre-processing shutter shielding portion, and a pre-processing shutter seal which is a packing 70 inserted into a groove formed around the pre-processing opening to maintain airtightness at the boundary between the pre-processing shutter shielding portion and the pre-processing shutter housing.

[0070] The post-processing module 30 may include a post-processing shutter 36. The post-processing shutter 36 may include a post-processing shutter shielding portion 361, post-processing shutter housings 362, 363 in which a post-processing opening 360 is selectively shielded and opened / closed by the post-processing shutter shielding portion 361 is formed, and a post-processing shutter seal 352 which is a packing 70 inserted into a groove formed around the post-processing opening 360 to maintain airtightness at the boundary between the post-processing shutter shielding portion 361 and the post-processing shutter housings 362, 363.

[0071] The pre-processing seal 251, post-processing seal, inlet seal 151, and outlet seal 351 can be formed in an annular shape. The pre-processing shutter seal and post-processing shutter seal 352 can be formed in a rectangular peripheral shape with rounded corners. The specific operation and configuration of the pre-processing shutter 16 and post-processing shutter 36 will be described later in the explanation relating to Figures 23 to 26.

[0072] Figure 16 is a cross-sectional view showing the packing 70 of the trolley processing system 1 according to one embodiment of the present invention in a contracted state. Figure 17 is a cross-sectional view showing the packing 70 of the trolley processing system 1 according to one embodiment of the present invention in an expanded state.

[0073] The packing 70 is made of an elastic material and can maintain airtightness by adhering tightly to each component at the boundary between components. The packing 70 expands upon the inflow of air and can maintain airtightness by adhering tightly to each component. The fluid injected into the packing 70 may be other fluids, not just air.

[0074] Assume that the packing 70 is positioned at the boundary between the installation target M2 and the pressurization target M1. The installation target M2 is the object to which the packing 70 is installed, and the pressurization target M1 is the object to which the expanded packing 70 attempts to make contact. To illustrate with an example of a post-processing seal, which is a packing 70 installed on the front flange 213, the installation target M2 is the front flange 213 of the intermediate body 21, and the post-processing seal is inserted into a groove G1 formed in the front flange 213, thereby pressurizing the post-processing flange 313 of the post-processing module 30, which is the pressurization target M1. In addition, the rear flange 212, inlet flange 112, outlet flange 312, pre-processing shutter housing, and post-processing shutter housings 362 and 363 can be installation targets M2, and the pre-processing flange 113, pre-processing door flange 54, post-processing door flange, pre-processing shutter shielding part, and post-processing shutter shielding part 361 can be pressurization targets M1.

[0075] The packing 70 may include an expansion portion 71 and a sealing portion 72. The expansion portion 71 is the part that expands when air is injected. The expansion portion 71 is inserted into a groove G1 formed in an annular shape on the outer surface of the object to be installed M2. The outer surface of the object to be installed M2 can be recessed along the front-rear direction to form the groove G1. Therefore, the expansion portion 71 can be inserted into the groove G1 along the front-rear direction.

[0076] The expansion portion 71 contains an expansion space 710 into which air can flow. The expansion space 710 may have a cross-section that is narrower in the center with respect to the front-to-back direction, on a cross-section obtained by cutting the packing 70 along a direction perpendicular to the direction in which the packing 70 extends. The expansion portion 71 that forms the expansion space 710 may also have a narrow shape in the center, similar to the expansion space 710. The expansion space 710 and the expansion portion 71 of the packing 70 are inserted into the groove with such shapes, and before and after expansion occurs, expansion along the protruding direction (up and down direction in Figures 16 and 17) may occur before expansion in the thickness direction (left and right direction in Figures 16 and 17).

[0077] The outer boundary 711b of the groove of the expansion space 710 may have a shape that bulges outward from the groove. The outer boundary of the groove of the expansion space may also have a shape that is not flat, but has curves or bent sections, such as a wave shape or a sawtooth shape.

[0078] The sealing portion 72 is connected to the side of the expansion portion 71 that faces outward from the groove G1, and is the part that can come into contact with the pressurized object M1. As the expansion portion 71 expands, the sealing portion 72 is pushed out of the groove G1 by the expansion portion 71, pressurizing the pressurized object M1, in order to maintain airtightness at the boundary between the installation object M2 and the pressurized object M1. Unlike the expansion portion 71, there is no part inside the sealing portion 72 into which fluid can flow and expand, thus providing rigidity to the packing 70.

[0079] The thickness of the sealing portion 72 can be less than the thickness of the expansion portion 71. Therefore, a step can be formed at the boundary between the sealing portion 72 and the expansion portion 71. Such a step may be formed only on one side in the thickness direction (the right side in Figures 16 and 17), as shown in the figures, or on both sides. A step is formed between the sealing portion 72 and the expansion portion 71, and a locking step portion M21 is also formed in the groove G1 of the installation target M2, which is a part of the sealing portion 711 that forms such a step, and locking step portion M21 is formed to lock into the locking portion 712, thereby preventing the packing 70 from coming out of the groove. Furthermore, even if the sealing portion 72 is in contact with the pressurized object M1, but the inner surface of the expansion portion 72 in the groove cannot make proper contact with the side located inside the groove G1, the locking portion 712 can be locked into the locking step portion M21, and the packing 70 and the installation target M2 can be sealed.

[0080] The corners at both ends of the sealing portion 72 in the thickness direction may be chamfered or rounded. Depending on the shape of the sealing portion 72, only the ends of the sealing portion 72 in the thickness direction may be in contact with the pressurized object M1, while the center may not be in contact, thus preventing a situation in which airtightness is poorly maintained.

[0081] A packing 70 according to one embodiment of the present invention may further include a nipple connected to the expansion section 71 to allow air to enter and exit the expansion space 710. The nipple is connected to an air supply means and can communicate with the expansion space 710 and transmit air supplied from the air supply means to the expansion space 710. Air contained in the expansion space 710 can also be discharged to the outside through the nipple. Although the shape of the nipple is omitted in Figures 16 and 17, the nipple is formed in a form that extends from the bottom to the top of the drawing, and its upper end can be connected to the expansion section 71.

[0082] Figure 18 shows a cross-section of the packing 70b and the structure of the nipple N1 according to a first modified example of one embodiment of the present invention. Figure 19 shows the arrangement of nipple installation locations P1 and P2 and nipple fixing part N11 on the packing 70b according to a first modified example of one embodiment of the present invention.

[0083] The packing 70b of the first modified example includes a nipple fixing portion N11. The nipple fixing portion N11 is positioned between the expansion portion 71b and the nipple N1 outside the boundary of the expansion space 710b to fix the nipple N1 to the expansion portion 71b, and extends along the direction in which the expansion portion 71b extends. Thus, as shown in Figure 19, the nipple fixing portion N11 can also be formed in an annular shape, like the expansion portion 71b. The nipple fixing portion N11 surrounds the periphery of the nipple N1 in the portion where the nipple N1 is positioned, and is sandwiched between the expansion portion 71b and the nipple N1, so that the nipple N1 does not easily detach from the expansion portion 71. The nipple fixing portion N11 can be made of stainless steel tape.

[0084] In the first modified example, the side of the sealing portion 72b that faces outward from the groove G2 can be recessed inward from the groove G2, forming irregularities 721b. Due to the formed irregularities 721b, even if the sealing portion 72b deforms while in close contact with the pressurized object M1, the state of close contact with the pressurized object M1 can be easily maintained.

[0085] In the first modified example, the packing fixing bolts included in the nipple N1 and packing 70b can be arranged at a plurality of nipple installation locations P1 and P2 that are spaced apart along the circumferential direction of the expansion portion 71b. The nipple N1 can supply fluid to the packing 70b as described above, and the packing fixing bolts can be used to fix the packing 70b so that it does not detach from the groove G2, without supplying fluid to the packing 70b. The nipple N1 can be connected to the fluid supply location P2 among the nipple installation locations P1 and P2, and the packing fixing bolts can be connected to the packing fixing location P1 among the nipple installation locations P1 and P2. The packing fixing locations P1 can be arranged at the vertices when the packing 70b is viewed as a rectangle, and the fluid supply locations P2 can be arranged at the corners of the packing 70b. However, another nipple may be connected to the packing fixing point P1 to supply fluid to the packing 70b.

[0086] Figure 20 shows a cross-section of packing 70c and the structure of nipple N2 according to a second modified example of one embodiment of the present invention.

[0087] Unlike the first modification, the packing 70c of the second modification does not have a nipple fixing portion N11. Therefore, the depth of the groove G3 can be even shallower than in the first modification, and since the nipple fixing portion N11 does not need to be surrounded by the expansion portion 71c, the length of the expansion portion 71c along the depth direction can be smaller than in the first modification. Since the nipple N2 does not need to be fixed by the nipple fixing portion N11, the fixing portion can be formed more simply than in the first modification. The shapes of the expansion space 710c and the sealing portion 72c may be the same in the first and second modifications.

[0088] Figure 21 shows a cross-section of packing 70d and the structure of nipple N2 according to a third modified example of one embodiment of the present invention.

[0089] In the third modified example, the thickness of the thickest part of the inner end of the groove in the expansion portion 71d of the packing 70d can be formed to be greater than the thickness of the sealing portion 72d. The thickness of the inner end of the groove in the expansion portion 71d can increase toward the inside of the groove G4 and then decrease. Thus, the inner end of the groove can include a portion in which the thickness increases toward the inside of the groove G4 and a portion in which the thickness decreases toward the inside of the groove G4 from the thickest part of the inner end of the groove. A fitting groove G41 having a shape corresponding to the shape of the inner end of the groove can be formed inside the groove G4 so that such an inner end of the groove of the expansion portion 71d is fitted into. However, the shape of the expansion space 710d can be the same as in the other modified examples, and the same nipple N2 as in the other modified examples can be used.

[0090] Figure 22 shows a cross-section of the packing 70e and the structure of the nipple N1 according to a fourth modified example of one embodiment of the present invention.

[0091] In the fourth modification, the thickness of the thickest part of the inner end of the groove of the expansion portion 71e of the packing 70e can be formed to be greater than the thickness of the sealing portion 72e. The thickness of the inner end of the groove of the expansion portion 71e can increase toward the inside of the groove G5. A fitting groove G51 having a shape corresponding to the shape of the inner end of the groove can be formed inside the groove G5 so that the inner end of the groove of such an expansion portion 71d is fitted into place. In the fourth modification, as in the first modification, a nipple N1 on which a nipple fixing portion N11 can be arranged can be used.

[0092]

[0093] Transfer section

[0094] A trolley processing system 1 according to one embodiment of the present invention may include a transfer section. The transfer section may include a pre-processing transfer member 142 positioned inside the pre-processing module 10 for the transfer of the trolley C. The transfer section may include an intermediate transfer member 242 positioned inside the intermediate module 20 for the transfer of the trolley C. The transfer section may include a post-processing transfer member 342 positioned inside the post-processing module 30 for the transfer of the trolley C. The pre-processing transfer member 142, the intermediate transfer member 242, and the post-processing transfer member 342 may be positioned spaced apart from each other along the front-rear direction. The pre-processing transfer member 142, the intermediate transfer member 242, and the post-processing transfer member 342 may each consist of a conveyor belt positioned in the front-rear direction at the lower part inside the pre-processing support frame 141 and rotating frame 241 of the pre-processing support means 14, and the post-processing support frame 341 of the post-processing support means 34, and capable of moving the trolley C, which is placed above it, along the front-rear direction. However, if the device can move the object it is placed on, then a component other than a conveyor belt can be used as the transfer mechanism.

[0095]

[0096] Shutter 16, 36

[0097] Figure 23 is a view along the front of the post-processing shutter 36 of the trolley processing system 1 according to one embodiment of the present invention, in a closed state. Figure 24 is a view of the post-processing shutter 36 in a partially open state according to one embodiment of the present invention. Figure 25 is a view of the upper housing 362 of the post-processing shutter separated from the lower housing 363 of the post-processing shutter according to one embodiment of the present invention. Figure 26 is a view of the state in Figure 25, in which the post-processing shutter shielding portion 361 has been discharged to the outside.

[0098] Referring to the drawings, the trolley processing system 1 according to one embodiment of the present invention may include a pre-processing shutter 16 and a post-processing shutter 36. The pre-processing module 10 may include a pre-processing shutter 16 that selectively divides the internal space of the pre-processing body 11 along the front-rear direction. The post-processing module 30 may include a post-processing shutter 36 that selectively divides the internal space of the post-processing body 31 along the front-rear direction.

[0099] The pre-processing shutter 16 may include a pre-processing shutter shielding portion, a lower housing of the pre-processing shutter in which a pre-processing opening is formed, which is opened and closed by the pre-processing shutter shielding portion, and an upper housing of the pre-processing shutter in which the pre-processing shutter shielding portion is located when the pre-processing opening is open. The upper housing of the pre-processing shutter can be detachably coupled to the upper side of the lower housing of the pre-processing shutter.

[0100] The post-processing shutter 36 may include a post-processing shutter shielding portion 361, a lower housing 363 of the post-processing shutter in which a post-processing opening 360, which is opened and closed by the post-processing shutter shielding portion 361, is formed, and an upper housing 362 of the post-processing shutter in which the post-processing shutter shielding portion 361 is located when the post-processing opening 360 is open. The upper housing 362 of the post-processing shutter can be detachably coupled to the upper side of the lower housing 363 of the post-processing shutter.

[0101] The post-processing shutter 36 will be described in detail below, but this description of the post-processing shutter 36 can be directly applied to the pre-processing shutter 16 by reversing the front-to-back direction and changing the object on which the shutter is formed from the post-processing module 30 to the pre-processing module 10.

[0102] The lower housing 363 of the post-processing shutter may include a lower plate 3631 of the post-processing shutter that shields a portion of the internal space of the post-processing module 30 to form a post-processing opening 360, and a lower projection 3632 of the post-processing shutter that protrudes above the post-processing module 30. The upper housing 362 of the post-processing shutter can be coupled above the lower projection 3632 of the post-processing shutter. That is, the upper housing 362 of the post-processing shutter can be positioned outside the post-processing body 31. When the post-processing shutter shielding portion 361 is detached from the post-processing opening 360 and the post-processing opening 360 is open, the post-processing shutter shielding portion 361 can be positioned in the internal space between the lower housing 363 and the upper housing 362 of the post-processing shutter.

[0103] The post-processing shutter shielding section 361 may include a plate-shaped post-processing shutter shielding plate 3611 and a post-processing shutter rack 3612 formed on the post-processing shutter shielding plate 3611. The post-processing shutter shielding plate 3611 may have a grid-like rib structure for pressure resistance. The post-processing shutter rack 3612 can mesh with a post-processing shutter gear 3641 included in the post-processing shutter drive unit 364. The post-processing shutter rack 3612 and the post-processing shutter drive unit 364 may have a configuration similar to the structure of the pinwheel 245 and sprocket 2441 of the rotating means 24 described later.

[0104] When the post-processing shutter motor 3643, which is connected to the gear of the post-processing shutter drive unit 364 via the post-processing shutter drive shaft 3642, operates, the post-processing shutter gear 3641 rotates, allowing the post-processing shutter shielding unit 361 to be raised and lowered. The post-processing shutter motor 3643 can be a device that receives power and produces driving force, such as a motor or actuator, and the post-processing shutter drive shaft 3642 is a shaft member positioned above the post-processing opening 360 so as to rotate in the left-right direction as its axial direction, receiving the driving force generated by such a post-processing shutter motor 3643.

[0105] The post-processing shutter shielding section 361 may include post-processing shutter guide rollers 3613. The post-processing shutter guide rollers 3613 are positioned adjacent to the periphery of the post-processing shutter shielding plate 3611 and can slide along a post-processing shutter guide rail 365, which is positioned adjacent to the post-processing opening 360 and oriented vertically. The action of the post-processing shutter guide rollers 3613 and the post-processing shutter guide rails 365 guides the up and down movement of the post-processing shutter shielding section 361 so that it does not detach from the post-processing opening 360. As shown in the figure, one post-processing shutter guide rail 365 may be positioned on each side of the post-processing opening 360, and four post-processing shutter guide rollers 3613 may be positioned, one each at the vertical and horizontal corners of the post-processing shutter shielding plate 3611, but the number and arrangement are not limited thereto.

[0106] The upper housing 362 of the post-processing shutter can be detachably coupled to the lower housing 363 of the post-processing shutter. After separating the upper housing 362 of the post-processing shutter from the lower housing 363 of the post-processing shutter, as shown in Figure 25, the post-processing shutter shielding portion 361 can be moved upward, as shown in Figure 26, to detach the post-processing shutter shielding portion 361 from the lower housing 363 of the post-processing shutter. After maintenance is complete, the post-processing shutter shielding portion 361 can be inserted downward into the lower housing 363 of the post-processing shutter, and the upper housing 362 of the post-processing shutter can be coupled to the lower housing 363 of the post-processing shutter. The post-processing shutter 36 has such a detachable structure, making it easy to manage the post-processing shutter shielding portion 361 and the upper housing 362 of the post-processing shutter.

[0107]

[0108] Rotating means 24 and fixing means 26

[0109] Figure 27 is a perspective view showing the state of the rotating means 24 and the trolley C before the trolley C is fixed by the fixing means 26 according to one embodiment of the present invention. Figure 28 is a view of the state in Figure 27 along the front.

[0110] Referring to the drawings, the trolley processing module of the trolley processing system 1 according to one embodiment of the present invention may include a rotating means 24 and a fixing means 26. In one embodiment of the present invention, the trolley processing module may be an intermediate module 20, where the module for pre-processing of the trolley C may be a pre-processing module 10, the module for post-processing of the trolley C may be a post-processing module 30, and the processing body of the trolley processing module may be an intermediate body 21. Hereinafter, the intermediate module 20 will be described as the trolley processing module.

[0111] The fixing means 26 is provided to fix the trolley C as it enters the inside of the intermediate body 21. The rotating means 24 is provided to rotate the trolley C, which is fixed by the fixing means 26, relative to the intermediate body 21, with the front-rear direction as the axis. In other words, the direction in which the trolley C moves within the trolley processing system 1 and the axial direction in which the trolley C rotates due to the rotating means 24 can coincide. The fixing means 26 plays the role of fixing the trolley C to the rotating means 24 so that the trolley C does not detach or the products inside the trolley C do not detach when the trolley C is rotated by the rotating means 24.

[0112] The rotating means 24 may include a rotating frame 241. The rotating frame 241 is a frame having a rotating space inside, which is a space into which the trolley C enters. The external appearance of the rotating frame 241 can be formed in a cylindrical shape, but it does not have to be cylindrical as a whole. The rotating frame 241 may include a plurality of disc-shaped members arranged at a distance from each other along the front-rear direction, with an opening into which the trolley C can be inserted, and a plurality of connecting ribs connecting these along the front-rear direction, thus having a form similar to a cylindrical framework. The pre-processing support frame 141 of the pre-processing module 10 and the post-processing support frame 341 of the post-processing module 30 may have shapes similar to the rotating frame 241.

[0113] The connecting ribs can be positioned adjacent to the opening of the disc-shaped member. The transfer assist rollers 243 can be rotatably coupled to the inside of the connecting ribs. An intermediate transfer member 242, which is a transfer member of the trolley C, can be positioned adjacent to the opening of the disc-shaped member, and the transfer assist rollers 243 can assist the transfer of the trolley C by the intermediate transfer member 242. Multiple transfer assist rollers 243 can be positioned to rotate freely. The transfer assist rollers 243 can be positioned on at least one of the upper, lower, left, or right sides of the opening of the disc-shaped member. The pre-processing support means 14 and the post-processing support means 34 may have configurations similar to those of the transfer assist rollers 243.

[0114] Figure 29 is a perspective view showing the state in which the trolley C is fixed by the fixing means 26 according to one embodiment of the present invention. Figure 30 is a perspective view of the fixing means 26 of the trolley processing system 1 according to one embodiment of the present invention.

[0115] The fixing means 26 may include a fixed operating part 262 and a fixed drive unit 261 for operating the fixed operating part 262. The fixed operating part 262 and the fixed drive unit 261 can be separated from each other or in contact with each other. The fixed operating part 262 is coupled to the rotating means 24 and rotates together with the rotation of the rotating means 24, while the fixed drive unit 261 is coupled to the intermediate body 21 and is not affected by the rotation of the rotating means 24. When the fixed drive unit 261 operates the fixed operating part 262, it is in contact with the fixed operating part 262 and the fixed drive unit 261 does not change the state of the fixed operating part 262, and when the trolley C is rotated by the rotating means 24, the fixed drive unit 261 and the fixed operating part 262 can be separated from each other.

[0116] The fixed actuation unit 262 is selectively placed in either a fixed state or a released state. In the fixed state, the fixed actuation unit 262 deforms due to the fixed drive unit 261, pressurizing the trolley C that has entered the inside of the intermediate body 21, and clamping and fixing it between itself and the rotating means 24. In the released state, the fixed actuation unit 262 detaches from the trolley C, allowing the trolley C to move along the front-rear direction and detach from the rotating means 24.

[0117] The fixed drive unit 261 is provided to detachably contact the fixed operating unit 262 and to transition the state of the fixed operating unit 262. That is, by operating the fixed drive unit 261, the fixed operating unit 262 can transition from a fixed state to a released state, or from a released state to a fixed state.

[0118] A fixed actuation unit 262 according to one embodiment of the present invention may have a link structure. Specifically, the fixed actuation unit 262 may include a four-bar link 2622, a toggle link 2624, and a pressure plate 2621. The four-bar link 2622 is a rhomboid-shaped part formed by the joining of four links, and can be coupled to a rotating frame 241 and a fixed member 2623 that does not have relative movement to the rotating frame 241. When the upper end of the four-bar link 2622 is pressed downward by the link actuation member included in the fixed drive unit 261, the distance between the upper and lower ends of the four-bar link 2622 decreases and the distance between the left and right ends increases. When the upper end of the four-bar link 2622 is pressed downward again by the fixed drive unit 261 while the distance between the upper and lower ends of the four-bar link 2622 has decreased, the distance between the upper and lower ends of the four-bar link 2622 recovers and the distance between the left and right ends decreases. To enable such recovery movements, the four-bar link 2622 can be equipped with spring-like elastic members that connect each link, as well as locking structures for each link.

[0119] The toggle link 2624 is connected to the left and right ends of the four-bar link 2622 so as to rotate in accordance with the movement of the four-bar link 2622. The toggle link 2624 is configured to perform a toggle action like a toggle clamp when the distance between the left and right ends of the four-bar link 2622 widens, pushing downward the pressure plate 2621 connected to the lower end of the toggle link 2624 and fixing it in that position. When the distance between the left and right ends of the four-bar link 2622 narrows, the pressure plate 2621 moves upward.

[0120] The pressure plate 2621 is a plate that applies downward pressure to the trolley C. When fixed, it descends to apply pressure to the trolley C, and when released, it rises and detaches from the trolley C. The pressure plate 2621 applies pressure to the trolley C against the rotating mechanism 24. With the trolley C placed on the inner surface of the rotating mechanism 24, the pressure plate 2621 applies pressure, allowing the trolley C to be clamped and fixed between the pressure plate 2621 and the inner surface of the rotating mechanism 24.

[0121] The link operating member included in the fixed drive unit 261 can be an air cylinder capable of vertical movement, but any device that can pressurize the link structure by raising and lowering can be used as a link operating member.

[0122] In one embodiment of the present invention, the four-bar link 2622 is described as being able to expand or contract along the left-right direction, but the four-bar link 2622 may also be arranged to expand or contract along the front-back direction.

[0123] Figure 31 is a perspective view illustrating the state in which the trolley C rotates while being fixed by the fixing means 26 according to one embodiment of the present invention. Figure 32 is a view of the state in Figure 31 along the front. Figure 33 is a diagram illustrating the rotation drive unit 244 of the trolley processing system 1 according to one embodiment of the present invention.

[0124] The rotating means 24 may include a pinwheel 245 coupled to the rotating frame 241 for rotation of the rotating frame 241. The pinwheel 245 can be formed in such a way that multiple pins are spaced apart along the circumferential direction of the wheel. Not all pins are shown in Figures 27 and 31, and the structure of the pins and wheel can be seen in Figure 33. The wheel of the pinwheel 245 is spaced apart in the front-rear direction from the disc-shaped member of the rotating frame 241 and can be connected to the disc-shaped member by connecting ribs. Thus, the trolley C can pass through the center of the pinwheel 245. Multiple pins can be coupled to the wheel so as to be rotatable in the front-rear direction as the axial direction. Thus, excessive force is prevented from being applied to the pins by the sprocket 2441, and damage or wear of the pins and sprocket 2441 can be prevented.

[0125] The rotating means 24 may include a rotary drive unit 244. The rotary drive unit 244 rotates the rotating frame 241 relative to the intermediate body 21 with the front-rear direction as the axial direction. The rotary drive unit 244 can be housed inside the protruding body 217.

[0126] The rotary drive unit 244 may include a sprocket 2441 that meshes with the pinwheel 245 and rotates axially in the front-rear direction, causing the pinwheel 245 to rotate as it rotates. The sprocket 2441 may be located outside the pinwheel 245. The rotary drive unit 244 may include a rotary drive motor 2442 that transmits a driving force for rotation to the sprocket 2441. The rotary drive motor 2442 may be a device that receives power and generates a driving force, such as a motor or actuator.

[0127] In the tooth profile of the sprocket 2441, the space between each tooth is larger than the space occupied by the pins of the pinwheel 245, allowing for ample clearance. Therefore, even if a deviation occurs between the sprocket 2441 and the pinwheel 245 due to device expansion or other reasons, the meshing state between the sprocket 2441 and the pinwheel 245 can be maintained.
