Abstract
Description
Technical Field
[0001] This disclosure relates to storage devices and cooling systems. Background Technology
[0002] Japanese Patent No. 7133736 discloses a coolant supply device comprising a coolant tank, a circulation path, and a foreign matter capture unit. The coolant tank stores coolant supplied from the machine tool's base. The circulation path is configured to return coolant from the coolant tank to the coolant tank via the foreign matter capture unit. The foreign matter capture unit is constructed of a cyclone separator that uses centrifugal force to capture foreign matter such as chips or sludge contained in the coolant. Summary of the Invention
[0003] However, Japanese Patent No. 7133736 does not disclose any content related to the discharge of foreign matter captured by the cyclone separator. There is room for improvement in the structure for discharging foreign matter.
[0004] The present disclosure provides a storage device for storing processing debris separated by a separation device that separates the processing debris contained in a liquid from the liquid. The storage device comprises: a container for storing the processing debris; a housing for receiving the container and having an opening for removing the container and an input port connected to the separation device, which is different from the opening; and a cover for covering the opening.
[0005] Another aspect of this disclosure is a cooling system comprising the aforementioned storage device and the aforementioned separation device. Attached Figure Description
[0006] Figure 1 This is a schematic diagram of the cooling system.
[0007] Figure 2 This is a diagram showing the separation and storage devices.
[0008] Figure 3 It is a diagram showing the positional relationship between the opening of the housing and the separation device.
[0009] Figure 4 This is a diagram showing a modified example of a separation device and a storage device. Detailed Implementation
[0010] A can-shaped container is known for storing foreign matter (processing chips) captured by a cyclone separator (separation device). The can-shaped container has an opening at one end, which is sealed with a threaded or cap-type lid. This lid is connected to the separation device via a pipe. When the amount of processing chips stored in the can-shaped container increases, the lid is removed, and the processing chips are scraped out from the opening at the end of the can-shaped container. This scraping operation is cumbersome. Furthermore, if the processing chips adhere to the mating surface of the lid that engages with the can-shaped container, it is difficult to seal the opening at the end of the can-shaped container with the lid, requiring cleaning.
[0011] The purpose of the following disclosure is to solve the aforementioned problems. In the following disclosure, the upward and downward directions are defined. The upward direction is the direction opposite to the direction of gravity. The downward direction is the direction of gravity.
[0012] like Figure 1 As shown, the cooling system 10 is a system that separates machining chips from a coolant containing machining chips generated during machining on the machine tool 12 and supplies the coolant containing the separated machining chips to the machine tool 12. Examples of machine tools 12 include cutting machines, lathes, and grinding machines. The coolant is a liquid. Typically, a liquid containing a water-soluble agent dissolved in water is used as the coolant. The coolant is used to improve machining performance during machining on the machine tool 12, to cool machining heat, or to remove machining chips generated during machining from the machine.
[0013] The cooling system 10 includes a first liquid tank 14, a second liquid tank 16, a coolant receiving component 18, a first hydraulic transfer pump 20, a second hydraulic transfer pump 22, a transfer pump 24, a separation device 26, and a storage device 28.
[0014] The first liquid tank 14 is a tank for storing coolant containing machining debris. The first liquid tank 14 is divided into a wastewater tank 14_1 and a primary cleaning tank 14_2 by a porous filter element 29. The wastewater tank 14_1 and the primary cleaning tank 14_2 are connected via the porous filter element 29. The porous filter element 29 divides the first liquid tank 14 into the wastewater tank 14_1 and the primary cleaning tank 14_2. The porous filter element 29 captures machining debris contained in the coolant stored in the wastewater tank 14_1. Thus, the coolant stored in the primary cleaning tank 14_2 becomes coolant with machining debris removed. However, the porous filter element 29 cannot completely capture the machining debris. Therefore, the coolant stored in the primary cleaning tank 14_2 contains machining debris. However, the amount of machining debris contained in the coolant stored in the primary cleaning tank 14_2 is less than the amount of machining debris contained in the coolant stored in the wastewater tank 14_1.
[0015] The second liquid tank 16 is a secondary cleaning tank for storing coolant from which machining debris has been separated by the separation device 26. Because the coolant stored in the second liquid tank 16 passes through the separation device 26, it contains less machining debris than the coolant stored in the primary cleaning tank 14-2.
[0016] The coolant receiving component 18 is used to receive the coolant discharged from the machine tool 12 and send it into the wastewater tank 14-1. The coolant discharged from the machine tool 12 contains machining chips. The coolant receiving component 18 is, for example, provided on the top plate of the first coolant tank 14.
[0017] The first hydraulic transfer pump 20 is a pump that delivers the cooling hydraulic fluid stored in the primary cleaning tank 14-2 to the machine tool 12. The first hydraulic transfer pump 20 is, for example, installed on the top plate of the first liquid tank 14. Figure 1 In this system, there are two first hydraulic transfer pumps 20, but there can also be one, or even more than three. The coolant pumped to the machine tool 12 by the first hydraulic transfer pumps 20 is discharged, for example, to the splash guard of the machine tool 12.
[0018] The second hydraulic transfer pump 22 is a pump that pumps the coolant stored in the second liquid tank 16 to the machine tool 12. The second hydraulic transfer pump 22 is, for example, installed on the top plate of the second liquid tank 16. Figure 1 In this configuration, there may be one second hydraulic transfer pump 22, but there can also be two or more. The coolant pumped by the second hydraulic transfer pump 22 to the machine tool 12 is supplied, for example, to a through-hole formed in the spindle of the machine tool 12. In this case, the coolant is discharged from the through-hole of the tool mounted on the spindle to the machining section of the tool.
[0019] The transfer pump 24 is a pump that pressurizes the coolant stored in the primary cleaning tank 14-2 to the separation device 26. The transfer pump 24 is, for example, installed on the top plate of the first liquid tank 14. The transfer pump 24 supplies the coolant stored in the primary cleaning tank 14-2 to the separation device 26 via the input line 40.
[0020] Separator 26 is a separator for separating machining chips contained in the coolant. Separator 26 can also be a cyclone filter. Separator 26 separates machining chips from the coolant supplied from the primary cleaning tank 14-2 via inlet pipe 40, and supplies the coolant with separated machining chips to the second liquid tank 16 via outlet pipe 42. Figure 2 As shown, the separation device 26 has an input section 30, a clean output section 32, a dirty output section 34, and a main body section 36.
[0021] The input section 30 is, for example, provided on the upper side of the main body 36. The input section 30 is connected to the input pipe 40 and the delivery pump 24. Figure 1The clean output section 32 is provided, for example, at the upper part of the main body 36 and is connected to the output pipe 42. The dirty output section 34 is provided, for example, at the lower part of the main body 36 and is connected to the storage device 28.
[0022] The main body 36 is the part that performs the process of separating machining chips from the coolant. When the separating device 26 is a cyclone filter, the main body 36 separates the machining chips from the coolant using centrifugal force. In this case, the coolant flowing in from the inlet 30 rotates within the main body 36. The machining chips contained in the coolant settle downwards near the outer wall of the cyclone filter due to the centrifugal force generated by the rotation, and flow out along with a portion of the coolant through the dirty outlet 34 into the storage device 28. As a result, the center of the cyclone filter contains almost no machining chips, and clean coolant is supplied from the clean outlet 32 to the outlet pipe 42.
[0023] Storage device 28 is a device for storing processing chips separated by separation device 26. Storage device 28 includes housing 50, container 52 and cover 54.
[0024] The housing 50 is located below the separating device 26. The housing 50 is, for example, provided on the top plate of the first liquid tank 14. The housing 50 is configured to receive the container 52. The housing 50 has a bottom wall 60, side walls 62, and an opening 64. The side walls 62 are connected to the edges of the bottom wall 60 and extend from the bottom wall 60 in the direction opposite to the direction of gravity (upward). The opening 64 is provided for removing the container 52. The opening 64 is located on the side opposite to the bottom wall 60 and is surrounded by the upper end of the side wall 62.
[0025] The housing 50 can also be configured such that the interior of the housing 50 can be visually observed from the outside. For example, the entire housing 50 can be made of transparent resin, glass, or the like. Alternatively, a window can be formed in a part of the housing 50. When the housing 50 is configured such that the interior can be visually observed from the outside, the operator can confirm the storage status of the housing 50 even without observing the interior of the housing 50 through the opening 64.
[0026] An input port 66 is formed separately from the opening 64 in the housing 50. The input port 66 is located below the opening 64 and communicates with the dirt output section 34 of the separation device 26. The input port 66 can also communicate with the dirt output section 34 via a pipe 68.
[0027] Processing chips are supplied from the separator 26 along with a small amount of coolant to the input port 66. A discharge section 70 may also be provided in the housing 50 to allow the coolant flowing from the input port 66 to exit through the housing 50.
[0028] In this embodiment, the discharge section 70 has a first discharge pipe 70A and a second discharge pipe 70B. The first discharge pipe 70A is installed on the side wall 62 of the housing 50, communicating the interior of the housing 50 with the primary cleaning tank 14_2. The second discharge pipe 70B is installed on the bottom wall 60 of the housing 50, communicating the interior of the housing 50 with the primary cleaning tank 14_2.
[0029] Alternatively, the discharge section 70 may have only one of the first discharge pipe 70A and the second discharge pipe 70B. Alternatively, the discharge section 70 may be a through hole formed in the housing 50 instead of the first discharge pipe 70A and the second discharge pipe 70B. Through this through hole, the discharge section 70 allows the coolant present in the housing 50 to flow to the primary cleaning tank 14-2. The through hole may also be closed by a sealing member such as a cap or plug. When the through hole is closed by a sealing member, the sealing member can be removed from the through hole during any opening period, such as maintenance. Alternatively, the discharge section 70 may connect the housing 50 to the coolant receiving member 18, or the housing 50 to the wastewater tank 14-1.
[0030] Container 52 is a component for storing processing chips. Container 52 is housed inside housing 50. The opening of container 52 is located at the upper end, facing the same direction as the opening 64 of housing 50.
[0031] The opening of container 52 is located below the input port 66. Therefore, the machining chips flowing in from the input port 66 are guided by gravity and stored in container 52.
[0032] The container 52 can be removed from the opening 64 of the housing 50. For example, when the amount of machining chips stored in the container 52 increases, the container 52 is removed from the opening 64. In this case, the container 52 without machining chips is returned to the interior of the housing 50. A handle 52A is formed on the upper part of the container 52. Alternatively, the handle 52A may not be formed.
[0033] Container 52 can also be formed as a bag-shaped membrane. In this case, the weight of container 52 can be reduced, resulting in easier handling of container 52 containing processing chips.
[0034] The container 52 can also be configured to allow coolant to pass through. For example, by forming multiple micropores in the container 52, coolant can pass through. Alternatively, by forming the container 52 into a mesh structure, coolant can pass through. When the container 52 is configured to allow coolant to pass through, machining chips supplied from the separator 26 can be stored, and coolant supplied along with the machining chips can be discharged to the outside of the container 52. As a result, the container 52 containing the machining chips is easy to handle. Furthermore, when the container 52 is configured to allow coolant to pass through, if the discharge section 70 is provided in the housing 50, the coolant can be returned to the primary cleaning tank 14-2.
[0035] The cover 54 covers the opening 64 of the housing 50. The cover 54 is supported on the upper part of the side wall 62 of the housing 50 surrounding the opening 64. The cover 54 can also be mounted to the housing 50 or the like in a manner that allows the opening 64 to be opened and closed. For example, the cover 54 can be detachably mounted to the housing 50, or it can be slidably mounted to the housing 50. In addition, the cover 54 can also be mounted to the housing 50 in a rotatable manner via a hinge or the like. A handle 54A is formed on the upper part of the cover 54. Alternatively, the handle 54A may not be formed.
[0036] The cover 54 can also be configured to allow visual inspection of the interior of the housing 50 from the outside of the cover 54. For example, the cover 54 can be made entirely of transparent resin, glass, or the like. Alternatively, a window can be formed in a portion of the cover 54. When the cover 54 is configured to allow visual inspection of the interior of the housing 50 from the outside of the cover 54, the operator can check the storage status of the housing 50 without removing the cover 54.
[0037] like Figure 3 As shown, the first projection area AR1 and the second projection area AR2 are separated when projected onto the imaginary surface VP, which is orthogonal to the removal direction FD of the container 52. The first projection area AR1 is the area of the separation device 26 projected onto the imaginary surface VP. The second projection area AR2 is the area projected onto the opening 64 of the imaginary surface VP.
[0038] By separating the first projection area AR1 from the second projection area AR2, the opening 64 can be easily exposed from the cover 54. Furthermore, the container 52 can be easily removed from the exposed opening 64.
[0039] In the storage device 28 of this embodiment, a container 52 for storing machining chips is housed inside the housing 50. An opening 64 for removing the container 52 is formed in the housing 50. As a result, the machining chips can be removed without scraping them off.
[0040] Furthermore, in the storage device 28 of this embodiment, the input port 66 communicating with the separation device 26 is not formed on the cover 54 covering the opening 64 of the housing 50, but is formed on the housing 50 itself. Therefore, machining debris is less likely to adhere to the mating surface of the cover 54. Additionally, by removing the container 52 during cleaning, machining debris will not adhere to the opening 64. As a result, compared to blocking the opening 64 with a threaded or cap-type cover, the cleaning process can be reduced.
[0041] The above-described embodiments can also be modified as follows.
[0042] like Figure 4 As shown, the opening 64 can also be configured such that the separating device 26 is located on a side of the housing 50 that is different from the removal direction FD of the container 52. Figure 4 The diagram shows a region where the separation device 26 is located relative to the housing 50 on the side opposite to the removal direction FD of the container 52. In this case, the opening 64 is located on the side opposite to the side wall 62 disposed between the bottom wall 60 and the upper wall 61. The opening 64 is surrounded by the ends of the bottom wall 60 and the upper wall 61. Furthermore, the cover 54 is mounted to the housing 50, etc., by a mounting member to prevent it from detaching from the housing 50.
[0043] Furthermore, the separating device 26 is not limited to the region located on the side opposite to the removal direction FD of the container 52 relative to the housing 50. For example, the separating device 26 may also be located in the region obliquely above the removal direction FD of the container 52 relative to the housing 50. Alternatively, the separating device 26 may also be located in the region obliquely below the removal direction FD of the container 52 relative to the housing 50.
[0044] In this way, when the opening 64 is arranged such that the separating device 26 is located in a region on the side of the housing 50 that is different from the removal direction FD of the container 52, the opening 64 can be easily exposed from the cover 54. In addition, the container 52 can be easily removed from the exposed opening 64.
