DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0010] [Embodiment 1] Hereinafter, the management system 100 according to the first embodiment of the present disclosure will be described in detail with reference to the drawings. The drawings used in the following description are schematic and do not necessarily reflect the actual product. For the convenience of illustration and ease of understanding, the scale and aspect ratio may be changed from the actual product and may be shown exaggerated. In the description of the drawings, the same parts are given the same reference numerals and the description will be omitted.
[0011] (Example of configuration of management system 100) Fig. 1 is a schematic diagram showing an example of a management system 100. As shown in Fig. 1, the management system 100 includes a shot processing equipment 10 for performing shot processing, and a management device 50 capable of communicating with a user device 40 installed in the shot processing equipment 10.
[0012] The shot processing equipment 10 is installed, for example, in a factory of a business that performs shot processing. The shot processing equipment 10 is equipped with a shot processing device 20, a storage 30 that stores consumables used in the shot processing, and a user device 40. The consumables include "projection material 26" and "parts worn by shot processing" described below. The "parts worn by shot processing" mainly include parts that constitute the projection mechanism 21, but also consumable parts such as parts of a conveyor that transports the projection material (for example, piping such as a screw, bucket, and hose) and a table on which a workpiece to be processed (hereinafter referred to as a work W) is placed.
[0013] The shot treatment is a process in which shot material 26 is projected from the projection mechanism 21 toward the workpiece W and collided with the workpiece W to process the surface of the workpiece W. "Shot treatment" includes blasting and shot peening. "Blasting" is a process for removing scales, deburring, polishing the surface, and imparting a matte texture to the workpiece W. "Shot peening" is a process for imparting compressive residual stress to the surface of the workpiece W to improve fatigue strength, wear resistance, stress corrosion cracking resistance, heat dissipation, etc.
[0014] The projection mechanism 21 projects the projection material 26 onto the workpiece W in the cabinet 22. Types of the projection mechanism 21 include, for example, an impeller-type projection mechanism and an air-type projection mechanism. In the first embodiment, a shot processing device 20 having an impeller-type projection mechanism 21a will be described as an example. The impeller-type projection mechanism 21a projects the projection material 26 onto the workpiece W by the centrifugal force of an impeller rotating at high speed. The air-type projection mechanism injects the projection material 26 onto the workpiece W by using air compressed by a compressor or the like. The air-type projection mechanism may be either a suction type or a direct pressure type.
[0015] The shot processing device 20 includes an impeller-type blasting mechanism 21a for blasting blast material 26 onto the workpiece W, a sensor 27 for detecting blasting conditions such as the blasting speed of the blast material 26, a cabinet 22, a screw conveyor 23, and a bucket elevator 24.
[0016] The blast material 26 is, for example, fine metal particles, but is not limited thereto, and may be non-metallic fine particles, such as glass, ceramic, sand, etc.
[0017] The workpiece W is typically made of a hard material such as metal, ceramic, glass, or plastic, but is not limited to these and may be, for example, an elastic body such as rubber carrying hard abrasive grains.
[0018] The blast material 26 projected by the impeller-type blasting mechanism 21a collides with the workpiece W and then falls onto the floor of the cabinet 22. The screw conveyor 23 is provided so that its upper end is located under the floor of the cabinet 22. The screw conveyor 23 transports the blast material 26 and the like that have fallen onto the floor of the cabinet 22 to a bucket elevator 24.
[0019] The bucket elevator 24 has a plurality of buckets. The bucket elevator 24 transports the blast material 26 and powder transported by the screw conveyor 23 upwards using a plurality of buckets. The blast material 26 transported upwards by the bucket elevator 24 is supplied to the blasting mechanism 21 and projected again. However, the blast material 26 transported by the bucket elevator 24 includes not only reusable blast material 26 but also blast material 26 that has been cracked or chipped by the shot processing and cutting powder of the workpiece W. For this reason, before being supplied again to the impeller-type blasting mechanism 21a, the reusable blast material 26 is removed by a sorting mechanism (not shown) and the reusable blast material 26 is supplied to the impeller-type blasting mechanism 21a. The sorting mechanism may be, for example, a wind sorter or a sieve.
[0020] As a result of removing the worn projection material 26, the projection material 26 in the shot processing device 20 is reduced. If the projection material 26 is reduced too much, it will affect the shot processing capacity, so new projection material 26 is supplied to the shot processing device 20 when the projection material 26 is reduced by a certain amount.
[0021] The sensor 27 detects projection conditions such as the projection speed of the projection material 26. Regarding the projection conditions, optimal conditions are set for each shot processing device 20 or each workpiece W according to the shape, material and other physical properties, processing purpose, etc. of the workpiece W. The shot processing device 20 projects the projection material 26 onto the workpiece W in accordance with the set projection conditions.
[0022] The projection conditions of the projection material 26 include the projection speed of the projection material 26, the projection amount of the projection material 26, the rotation speed of the impeller, and the value of the current flowing through the motor that rotates the impeller.
[0023] When the projection mechanism 21 is an air type, the projection conditions of the projection material 26 include the ejection speed of the projection material 26, the ejection amount of the projection material 26, the ejection pressure of the compressed air, etc. Although the term "ejection" is used when explaining air type projection, the term "ejection" may be read as "projection" as appropriate.
[0024] The sensor 27 is connected to the impeller-type projection mechanism 21a, and detects the projection speed of the projection material 26, the projection amount of the projection material 26, the rotation speed of the impeller, the current value flowing through the motor that rotates the impeller, and the like. Here, the projection speed of the projection material 26 may be calculated by calculation based on the current value of the impeller. Examples of sensors that detect these data include speed sensors, optical sensors, vibration sensors, and current sensors. Note that instead of the current value flowing through the motor that rotates the impeller, the voltage value applied to the motor or the power value supplied to the motor may be detected.
[0025] When the projection mechanism 21 is an air type, the sensor 27 connected to the projection mechanism 21 detects the above-mentioned ejection speed of the projection material 26, the ejection amount of the projection material 26, the ejection pressure of the compressed air, etc. Here, the ejection speed of the projection material 26 may be calculated by calculation based on the ejection speed of the compressed air. Examples of sensors that detect these data include a flow sensor, a pressure sensor, a vibration sensor, an acceleration sensor, and a gyro sensor.
[0026] The sensor 27 converts the detected data into an electrical signal and transmits it to the user device 40 .
[0027] Although not shown in the drawings, the shot processing device 20 is provided with a timer that measures the projection time of the projection material 26. The projection time measured by the timer is converted into an electrical signal and transmitted to the user device 40.
[0028] The storage 30 is a container for storing consumables used in the shot processing, that is, the projection material 26 and parts consumed by the shot processing. In the first embodiment, the case where the consumables managed by the management system 100 are the projection material 26 will be described as an example. Management of parts consumed by the shot processing will be described in the second embodiment. The container 30a constituting the storage 30 is provided with a sensor 31 for detecting the remaining amount of the stored projection material 26. Examples of sensors for detecting the remaining amount of the projection material 26 include a level gauge and a level switch. The sensor 31 may be of a paddle type, a piston type, a pendulum type, a sounding type, a capacitance type, a vibration type, an ultrasonic type, a microwave type, a radiation type, or the like, and is appropriately selected from these in accordance with the properties of the projection material 26 to be detected. The sensor 31 converts the detected remaining amount data into an electrical signal and transmits it to the user device 40. The inventory amount may be the amount remaining in container 30a, or the sum of the amount remaining in containers 30a that make up reservoir 30 and the amount remaining in the material storage location (not shown), but below, the remaining amount of projection material 26 in container 30a will be described as the "inventory amount."
[0029] The user device 40 is a device installed in the shot processing equipment 10, and is, for example, a general-purpose computer.
[0030] The user device 40 acquires information on the projection conditions, projection time, and initial value of the stock amount of the projection material 26 from the sensors 27 and 31 using a predetermined communication method. Hereinafter, when these sensors are not distinguished from each other, they are simply referred to as "each sensor." The communication may be performed either wired or wirelessly, and any communication method may be used as long as the communication between the sensors can be performed. In this embodiment, the communication between the sensors and the user device 40 is described as being performed using Wi-Fi (registered trademark). Note that the information on the projection conditions, projection time, and initial value of the stock amount of the projection material 26 means data detected by each sensor that is converted into an electrical signal. Therefore, the information on the projection conditions, projection time, and initial value of the stock amount of the projection material 26 may be rephrased as information indicating the projection conditions, projection time, and initial value of the stock amount of the projection material 26. An example of the "initial value of the stock amount" is the stock amount at the start time when the shot processing is started after the stock amount is adjusted.
[0031] The management device 50 is a device for managing consumables used in the shot processing equipment 10, and is, for example, a general-purpose computer. The installation location of the management device 50 is not particularly limited, but, for example, the management device 50 is installed in a management center of a supplier that develops a service providing consumables.
[0032] (Hardware configuration of user device 40 and management device 50) Next, the hardware configuration of the user device 40 and the management device 50 will be described with reference to Fig. 2. Fig. 2 is a block diagram showing the hardware configuration of the user device 40 and the management device 50.
[0033] First, a description will be given of the hardware configuration of the user device 40. As shown in Fig. 2, the user device 40 includes a processor 41, a ROM (Read Only Memory) 42, a RAM (Random Access Memory) 43, a storage device 44, a communication I / F (Interface) 46, and a display 47. Each component is connected to each other via a bus 45 so as to be able to communicate with each other.
[0034] The processor 41 is an arithmetic unit that executes various programs, such as a CPU (Central Processing Unit). The processor 41 reads programs from the ROM 42 or the storage device 44, and executes the various programs using the RAM 43 as a working area.
[0035] The ROM 42 stores various programs and various data. The RAM 43 temporarily stores programs or data as a working area. Note that computer-readable recording media are not limited to the ROM 42 and RAM 43, and may include EPROM (Erasable Programmable ROM), EEPROM (registered trademark) (Electrically Erasable Programmable ROM), etc.
[0036] The storage device 44 is configured with a hard disk drive (HDD), a solid state drive (SSD), a flash memory, or the like, and stores various programs and various data. The storage device 44 stores information regarding the projection conditions, projection time, and initial values of inventory amount of the projection material 26 transmitted from each sensor.
[0037] The display 47 is configured with a liquid crystal display or an organic EL display or the like, and displays various information.
[0038] The communication I / F 46 is implemented as hardware such as a network adapter, communication software, or a combination of these, and communicates with each sensor and with the management device 50. The communication between each sensor and the user device 40 has been described above. Although the communication between the user device 40 and the management device 50 will be described as being performed using the Internet, other communication methods may be used.
[0039] Next, the hardware configuration of the management device 50 will be described.
[0040] 2, the management device 50 includes a processor 51, a ROM 52, a RAM 53, a storage device 54, a communication I / F 56, and a display 57. Each component is connected to each other so as to be able to communicate with each other via a bus 55. The configurations of the processor 51, ROM 52, RAM 53, storage device 54, communication I / F 56, and display 57 are similar to the configurations of the processor 41, ROM 42, RAM 43, storage device 44, communication I / F 46, and display 47 of the user device 40 described above, and therefore description thereof will be omitted.
[0041] (Function of Processor 51) Next, functions of the processor 51 of the management device 50 will be described with reference to Fig. 3. Fig. 3 is a functional block diagram of the processor 51 of the management device 50. As shown in Fig. 3, in the management device 50 of this embodiment, the processor 51 executes a specific program to function as a data acquisition unit 511, a calculation unit 512, and an automatic ordering unit 513.
[0042] The data acquisition unit 511 acquires information relating to the projection conditions, projection time, and initial values of inventory amount of the projection material 26 from the user device 40. The data acquisition unit 511 stores the acquired information in the storage device 54. The calculation unit 512 calculates the required amount of projection material 26 based on the information acquired by the data acquisition unit 511. The automatic ordering unit 513 performs processing to automatically order the required amount calculated by the calculation unit 512.
[0043] (Automatic order processing flow) Next, an example of the flow of automatic order processing executed by the management system 100 will be described with reference to Fig. 4. Fig. 4 is a sequence chart showing an example of the flow of automatic order processing.
[0044] In step S101 , the processor 41 of the user device 40 acquires information on projection conditions, such as the projection speed of the projection material 26 , from the sensor 27 , and stores it in the storage device 44 .
[0045] The process proceeds to step S102, where the processor 41 of the user device 40 obtains information about the projection time of the projection material 26 from the timer and stores it in the storage device 44.
[0046] The process proceeds to step S103, where the processor 41 of the user device 40 acquires information about the initial value of the inventory amount of the projection material 26 from the sensor 31 and stores it in the storage device 44.
[0047] The process proceeds to step S104, where the processor 41 of the user device 40 transmits to the management device 50 information relating to the projection conditions, projection time, and initial values of the inventory amount of the projection material 26 acquired in the processes of steps S101 to S103.
[0048] In step S105, the processor 51 of the management device 50 acquires information relating to the projection conditions, projection time, and initial values of the inventory amount of the projection material 26 from the user device 40.
[0049] In step S106, the processor 51 of the management device 50 calculates the required amount of the projection material 26 based on the information related to the projection conditions, projection time, and initial value of the inventory amount of the projection material 26 acquired in the processing of step S105.
[0050] (Method of calculating the required amount of projection material 26) Here, an example of a method for calculating the required amount of projection material 26 will be described.
[0051] The processor 51 of the management device 50 calculates the amount of the projection material 26 used in the shot process using the projection conditions of the projection material 26 and the projection time of the projection material 26. Next, the processor 51 of the management device 50 subtracts the amount of the projection material 26 used from the initial value of the inventory amount of the projection material 26 to calculate the current inventory amount of the projection material 26.
[0052] Here, the processor 51 of the management device 50 may calculate the usage amount of the projection material 26 from the projection time for each of the varying projection conditions. The projection conditions may vary from moment to moment due to various factors such as the remaining amount of the projection material 26 in the shot processing device 20 and changes in the dust collection air volume. For example, if the projection conditions are set and managed in a table according to the remaining amount of the projection material 26 in the shot processing device 20, the dust collection air volume, etc., the projection conditions may vary from moment to moment due to changes in these conditions. The processor 51 of the management device 50 may calculate the usage amount for each specific point from the projection time for each of the varying projection conditions.
[0053] Furthermore, the processor 51 of the management device 50 may calculate the total usage amount of the projection material 26 from the relationship between the average value of the projection conditions and the cumulative projection time. For example, when the projection condition is the projection amount of the projection material 26, the "average value of the projection conditions" means the average value of the projection amount calculated from the sum of the projection amount when the dust collection air volume is A, the projection amount when the dust collection air volume is B, and the projection amount when the dust collection air volume is C. The average value of the projection conditions can be calculated in a similar manner even if the projection condition is the projection speed of the projection material 26, the rotation speed of the impeller, or the like.
[0054] Furthermore, the processor 51 of the management device 50 may calculate the total usage amount of the projection material 26 from the relationship between the preset projection conditions and the cumulative projection time.
[0055] Next, the processor 51 of the management device 50 compares the current inventory amount of the projection material 26 with the threshold value. This threshold value is appropriately set in advance through experiments, simulations, etc.
[0056] If the comparison result indicates that the current stock amount of the projection material 26 falls below the threshold, the processor 51 of the management device 50 calculates the amount of the projection material 26 required for the stock amount of the projection material 26 to exceed the threshold. At this time, the processor 51 of the management device 50 may calculate the amount of the projection material 26 required for the stock amount of the projection material 26 to exceed the threshold, taking into account the period from ordering the projection material 26 to the delivery date. This is because, if shot processing is performed during the period from ordering the projection material 26 to the delivery date, the stock amount of the projection material 26 continues to decrease.
[0057] The processor 51 of the management device 50 may plot the usage amount of the projection material 26 for each projection time of the projection material 26, and calculate the usage amount of the projection material 26 over the entire projection time by integrating the plotted trajectory.
[0058] In addition, the "calculation executed by the processor 51 of the management device 50" may include predicting the amount of projection material 26 required to exceed the inventory level of the projection material 26 when the current inventory level of the projection material 26 falls below a threshold, and determining whether the current inventory level of the projection material 26 has reached the line (threshold level) required for ordering.
[0059] The processor 51 of the management device 50 performs processing to automatically order the calculated required amount of projection material 26 (step S107).
[0060] 4 is merely an example, and new steps may be added without departing from the spirit of the invention. Also, the processes in steps S101 to S103 may be performed simultaneously.
[0061] [Modification of the first embodiment] Next, a modified example of the first embodiment will be described with reference to Fig. 5. Fig. 5 is a functional block diagram of the processor 51 of the management device 50. As shown in Fig. 5, the processor 51 of the management device 50 may function as a notification unit 514 that notifies the user device 40 instead of the automatic ordering unit 513.
[0062] In the above description, the process of automatically ordering the calculated required amount of projection material 26 has been described, but instead of such automatic ordering process, the processor 51 of the management device 50 may notify the user device 40 of information regarding the required amount of projection material 26. Information regarding the required amount of projection material 26 is, for example, information indicating the current stock amount of projection material 26, information indicating the usage amount of projection material 26, etc. On the display 47 of the user device 40, information indicating the current stock amount of projection material 26, information indicating the usage amount of projection material 26, etc. are displayed. This allows a user working at the shot processing equipment 10 to grasp the stock amount of projection material 26 without having to check the stock amount of projection material 26 himself, reducing the user's effort regarding inventory management.
[0063] Furthermore, the processor 51 of the management device 50 may notify a remote location of information regarding the required amount of the projection material 26 by wire or wirelessly using a LAN (Local Area Network) or the like. Examples of notification destinations include the supplier's purchasing person, the supplier's equipment maintenance department, the delivery destination's purchasing person, and the delivery destination's maintenance and inspection service department.
[0064] The processor 51 of the management device 50 may suggest placing an order at the same time as notifying the user device 40. For example, the processor 51 of the management device 50 may suggest by displaying on the display 47 of the user device 40, "The inventory of the projection material 26 will be low in x days. Would you like to place an order?" The suggestion method and notification method are not particularly limited, and may be set appropriately according to the circumstances of each user.
[0065] (Action and effect) As described above, the management system 100 according to the first embodiment provides the following advantageous effects.
[0066] The processor 51 of the management device 50 acquires information relating to the projection conditions of the projection material 26, acquires information relating to the projection time of the projection material 26, and acquires information relating to the initial value of the inventory amount of the projection material 26. The processor 51 of the management device 50 calculates the required amount of the projection material 26 based on the information relating to the projection conditions, the information relating to the projection time, and the information relating to the initial value of the inventory amount. The processor 51 of the management device 50 outputs information relating to the result of the calculation.
[0067] When the information on the calculation results is output to a user device 40 installed in the shot processing equipment 10, the user working at the shot processing equipment 10 does not need to check the stock of the projection material 26 himself, and the user's effort in inventory management is reduced. In other words, according to the above configuration, it is possible to reduce the user's effort in preventing operation stoppage due to a shortage of consumables (projection material 26), which in turn improves productivity.
[0068] When using the management system 100, the projection conditions of the projection material 26 are set as a prerequisite.
[0069] The information on the projection conditions includes at least one of the projection speed and projection amount of the projection material 26. The processor 51 of the management device 50 uses the projection speed or projection amount of the projection material 26 to accurately calculate the required amount of the projection material 26.
[0070] The processor 51 of the management device 50 may also perform processing to display information regarding the required amount of the projection material 26 on the display 47 of the user device 40. This eliminates the need for a user working at the shot processing equipment 10 to check the inventory of the projection material 26 himself, reducing the user's workload regarding inventory management.
[0071] In addition, the processor 51 of the management device 50 may perform processing to notify a remote location of information regarding the required amount of the projection material 26. This makes it possible to notify information regarding the required amount of the projection material 26 even if the shot processing equipment 10 is located in a remote location.
[0072] The processor 51 of the management device 50 may also perform processing to order the projection material 26 based on information regarding the required amount of the projection material 26. This eliminates the need for a user working at the shot processing equipment 10 to perform tasks such as ordering the projection material 26, confirming delivery dates with suppliers, and maintaining the shot processing equipment 20 until the projection material 26 is delivered, reducing the user's workload. Furthermore, the automatic ordering process can ensure stable operation of the shot processing equipment 10.
[0073] [Embodiment 2] Next, a second embodiment of the present disclosure will be described below. For convenience of description, the same reference numerals are given to members having the same functions as those described in the first embodiment, and the description thereof will not be repeated.
[0074] In the first embodiment, the projection material 26 is taken as a consumable item used in the shot processing, and a process for automatically ordering the projection material 26 is described. In the second embodiment, the components constituting the projection mechanism 21 are taken as consumable items used in the shot processing and described. As described above, the projection mechanism 21 may be either an impeller type or an air type.
[0075] FIG. 6 shows a distributor 70 that stirs the projection material 26, a control cage 71 that regulates the direction in which the projection material 26 is projected, and a blade 72 as representative examples of parts that may be replaced among the parts that make up the impeller-type projection mechanism 21a.
[0076] FIG. 7 shows a nozzle 75, an air jet 76, and a nozzle body 77 as representative examples of parts to be replaced in a suction-type projection mechanism 21b among air-type projection mechanisms.
[0077] FIG. 8 shows a nozzle 80, a nozzle body 81, and a nozzle clamp 82 as representative examples of parts to be replaced in a direct pressure type projection mechanism 21c among air type projection mechanisms.
[0078] Hereinafter, when there is no need to distinguish between these parts, they will simply be referred to as "each part." Since each part is a consumable item, it will need to be replaced if the amount of wear becomes too great. The inventory of each part is stored in the storage 30. When replacing a part, it will be taken out of the storage 30 and replaced.
[0079] The processor 51 of the management device 50 calculates the required amount of each part based on information on the projection conditions, projection time, and initial value of the inventory amount of each part. For an impeller, an example of the projection conditions of each part includes the rotation speed of the impeller and the value of the current flowing through the motor that rotates the impeller, and for the nozzle 75, an example of the projection conditions of the nozzle 75 includes the injection pressure of the compressed air injected from the nozzle 75.
[0080] (Method of calculating the required amount of each part) An example of a method for calculating the required amount of each part will be described with reference to Fig. 9. The horizontal axis of Fig. 9 indicates time, and the vertical axis indicates operation items of the shot processing equipment 10 and procurement items of consumables.
[0081] The processor 51 of the management device 50 may calculate the required amount of each part as γ when the following two conditions are satisfied. The two conditions are: Condition 1: T1-(T3+(T2×α))≦0, and Condition 2: β<γ. β and γ are omitted from FIG. 9.
[0082] T1 shown in FIG. 9 indicates the life of a consumable. An example of an input condition for T1 is the timing at which the consumable is replaced. The input condition for T1 may be a threshold value set based on the timing at which the consumable is replaced. The "input condition" here refers to the condition when a user working at the shot processing equipment 10 inputs data into the user device 40.
[0083] T2 indicates the delivery date of the consumable. The input condition for T2 is a predetermined value.
[0084] T3 indicates the projection time or the jetting time. If the consumables are components of the impeller-type projection mechanism 21a, T3 is the projection time. On the other hand, if the consumables are components of the air-type projection mechanism 21b, T3 is the jetting time. The input condition for T3 is the projection time or the jetting time after the replacement of the consumables.
[0085] α indicates the safety factor of the delivery date. The "safety factor of the delivery date" is an index that is set based on the concept of the delivery destination, the distance from the shipping destination to the facility, etc. The input condition for α is the safety factor of the delivery date.
[0086] β indicates the inventory amount at the delivery destination. The input condition for β is the inventory amount at the delivery destination.
[0087] γ indicates a pre-agreed order amount.
[0088] In FIG. 9, the period from t1 to t2 indicates T3, and the period from t2 to t3 indicates T2'. T2'=T2×α. Also, α>1. As shown in condition 1, when T3+T2' is equal to or greater than T1, the consumable is replaced. At this time, if condition 2 is satisfied, the processor 51 of the management device 50 may calculate the required amount as γ. In this case, the processor 51 of the management device 50 may perform a process of automatically ordering γ, which is a predetermined amount.
[0089] Next, the blade 72, which is one of the consumables, will be described with reference to FIG.
[0090] T1 shown in FIG. 10 indicates the lifespan of the blade 72 (600 hours). T2 indicates the delivery date of the blade 72 (120 hours). T3 indicates the projection time (450 hours). In FIG. 10, α is set to 1.5. Therefore, T2' is 180 hours. β, which is the inventory amount at the delivery destination, is set to 5 sets. γ, which is the predetermined order amount, is set to 8 sets.
[0091] 10, T1-(T3+(T2×α)) is -30, so condition 1 is satisfied. It is also assumed that condition 2 is satisfied. In this case, the processor 51 of the management device 50 can calculate the required amount of blades 72 as γ, and perform processing to automatically place an order at the timing indicated by t4.
[0092] Next, another example of a method for calculating the required amount of each part will be described with reference to Fig. 11. In the flowchart shown in Fig. 11, a flow relating to data exchange between user device 40 and management device 50 is omitted. In addition, the flowchart shown in Fig. 11 starts in a state where the projection time is reset.
[0093] In step S201, shot processing is performed in the shot processing equipment 10. Next, the processor 51 of the management device 50 judges whether the projection time is equal to or longer than a predetermined value. The predetermined value here is "T1-T2×α" explained in FIG. 9. If the judgment result in step S202 is NO, the process returns to step S201. On the other hand, if the judgment result in step S202 is YES, the process proceeds to step S203.
[0094] In step S203, processor 51 of management device 50 determines whether the stock amount of the given part is equal to or less than the required replacement amount. If the determination result in step S203 is YES, processor 51 of management device 50 performs processing to automatically order the given part. Processor 51 of management device 50 can calculate the difference between the stock amount and the required replacement amount as the required amount of the given part. If the determination result in step S203 is NO, processing proceeds to step S205.
[0095] In step S205, the processor 51 of the management device 50 determines whether the projection time is equal to or greater than T1. The process waits until the projection time becomes equal to or greater than T1 (NO in step S205). When the projection time becomes equal to or greater than T1, the process proceeds to step S206, where an arbitrary part is replaced.
[0096] In step S207, processor 51 of management device 50 determines whether the inventory amount of the given part is equal to or less than the required inventory amount. If the determination result in step S207 is YES, processor 51 of management device 50 performs processing to automatically order the given part. Processor 51 of management device 50 can calculate the difference between the inventory amount and the required inventory amount as the required amount of the given part. If the determination result in step S207 is NO, the series of processes ends.
[0097] 11 is merely an example, and new steps may be added without departing from the spirit of the invention. Also, the processes in steps S207 and S208 may be omitted.
[0098] In the second embodiment, similarly to the first embodiment, the processor 51 of the management device 50 may notify the user device 40 of information regarding the required amount of each part, instead of the automatic ordering process.
[0099] (Action and effect) As described above, according to the second embodiment, the following advantageous effects can be obtained.
[0100] The processor 51 of the management device 50 acquires information related to the projection conditions of the projection material 26, acquires information related to the projection time of the projection material 26, and acquires information related to the initial value of the inventory amount of parts consumed by the shot process. The processor 51 of the management device 50 calculates the required amount of parts consumed by the shot process based on the information related to the projection conditions, information related to the projection time, and information related to the initial value of the inventory amount. The processor 51 of the management device 50 outputs information related to the result of the calculation.
[0101] When the information regarding the results of the calculation is output to a user device 40 installed in the shot processing equipment 10, a user working at the shot processing equipment 10 does not need to check the inventory of parts consumed by shot processing himself / herself, thereby reducing the user's burden regarding inventory management.
[0102] The projection mechanism 21 may also be an impeller-type projection mechanism 21a. In this case, the information on the projection conditions includes at least one of information on the rotation speed of the impeller and information on the power of the impeller. The information on the power is either the current value flowing through the motor that rotates the impeller described above, the voltage value applied to the motor, or the power value supplied to the motor. The processor 51 of the management device 50 can calculate the required amounts of the distributor 70, the control cage 71, the blades 72, etc. by using the information on the rotation speed of the impeller or the information on the power of the impeller.
[0103] The projection mechanism 21 may also be an air-type projection mechanism 21b. In this case, the information on the projection conditions includes at least one of information on the injection pressure of the compressed air injected from the nozzle 75 and information on the injection amount of the projection material 26. The processor 51 of the management device 50 can calculate the required amounts of the nozzle 75, the air jet 76, the nozzle body 77, etc. by using the information on the injection pressure or the information on the injection amount of the projection material 26.
[0104] [Embodiment 3] Next, a third embodiment of the present disclosure will be described below. For ease of explanation, the same reference numerals will be given to members having the same functions as those described in the first embodiment, and the description thereof will not be repeated.
[0105] 12 is a schematic configuration diagram showing an example of a management system 200 according to embodiment 3. Embodiment 3 differs from embodiment 1 in that a sensor 28 is connected to the bucket elevator 24.
[0106] The sensor 28 is, for example, a current sensor that measures the value of a current flowing through a motor that drives the bucket elevator 24. The sensor 28 converts the detected current value into an electric signal and transmits it to the user device 40. Note that instead of a current sensor, the sensor 28 may be a voltage sensor that measures the voltage value applied to the motor, or a power sensor that measures the power supplied to the motor.
[0107] When the blast material 26 is collected and reused, the magnitude of the current flowing through the motor driving the bucket elevator 24 changes depending on the amount of the blast material 26 collected. Therefore, it is possible to estimate the amount of the blast material 26 collected based on the current value. Here, in order to calculate the required amount of the blast material 26, it is necessary to set the amount of the blast material 26 to be collected as reusable. In other words, the amount of the blast material 26 removed by the shot processing is taken into consideration. The amount of the blast material 26 removed may be calculated by referring to the processing capacity of the sorting mechanism described above (the suction air volume in the wind sorting, the mesh opening and vibration force in the sieve, etc.), or may be set based on experiments or simulations. The processor 51 of the management device 50 can accurately calculate the required amount of the blast material 26 by adding information on the collection conditions of the blast material 26 to the information described in the first embodiment.
[0108] (Automatic order processing flow) An example of the flow of automatic order processing executed by the management system 200 will be described with reference to Fig. 13. However, since the processing of steps S301 to S303 is similar to the processing of steps S101 to S103 shown in Fig. 4, the description will be omitted.
[0109] In step S304, the processor 41 of the user device 40 acquires information about the collecting conditions from the sensor 28, and stores the information in the storage device 44. The information about the collecting conditions is information indicating the current value measured by the sensor 28.
[0110] In step S305, the processor 41 of the user device 40 transmits to the management device 50 information regarding the projection conditions, projection time, initial value of the inventory amount, and collection conditions of the projection material 26 acquired in steps S301 to S304.
[0111] In step S306, the processor 51 of the management device 50 acquires, from the user device 40, information on the projection conditions, projection time, initial value of the inventory amount, and collection conditions of the projection material 26.
[0112] In step S307, the processor 51 of the management device 50 calculates the required amount of the projection material 26 based on the information on the projection conditions, projection time, initial value of the inventory amount, and collection conditions of the projection material 26 acquired in step S306.
[0113] In step S308, the processor 51 of the management device 50 performs processing to automatically order the required amount of the projection material 26 calculated in step S307.
[0114] In the third embodiment, similarly to the first embodiment, the processor 51 of the management device 50 may notify the user device 40 of information regarding the required amount of projection material 26, instead of automatic ordering processing.
[0115] (Action and effect) As described above, the management system 200 according to the third embodiment provides the following advantageous effects.
[0116] The processor 51 of the management device 50 further acquires information on recovery conditions for reusing the projection material 26 after projection, and calculates the required amount of projection material 26 based on the information on the projection conditions, the information on the projection time, the information on the initial value of the inventory amount, and the information on the recovery conditions. By adding the information on the recovery conditions to the information on the projection conditions, the information on the projection time, and the information on the initial value of the inventory amount, it becomes possible to accurately calculate the required amount of projection material 26.
[0117] The processor 51 of the management device 50 may also add information about the collection conditions when calculating the required amount of each part described in the second embodiment.
[0118] Furthermore, the processor 51 of the management device 50 may calculate the amount of projection material 26 used from a random number table that combines information about projection conditions and information about recovery conditions.
[0119] [Embodiment 4] Next, a fourth embodiment of the present disclosure will be described below. For ease of explanation, the same reference numerals will be given to members having the same functions as those described in the first embodiment, and the description thereof will not be repeated.
[0120] 14 is a schematic configuration diagram showing an example of a management system 300 according to embodiment 4. Embodiment 4 differs from embodiment 1 in that a sensor 29 for detecting the number of processed works W is provided in the cabinet 22.
[0121] The sensor 29 is, for example, an infrared sensor. The sensor 29 counts the number of workpieces W that are shot in the cabinet 22. The sensor 29 converts the counted number of workpieces W that are shot into an electric signal and transmits it to the user device 40. In the fourth embodiment, the number of workpieces W that are shot is used instead of the projection time of the projection material 26. This is because information regarding the projection time is obtained by calculation based on the number of workpieces W that are shot.
[0122] (Automatic order processing flow) An example of the flow of automatic order processing executed by the management system 300 will be described with reference to Fig. 15. However, since the processing of steps S401 and S403 is similar to the processing of steps S101 and S103 shown in Fig. 4, the description thereof will be omitted.
[0123] In step S402, the processor 41 of the user device 40 acquires information regarding the number of processed works W from the sensor 29, and stores the information in the storage device 44.
[0124] In step S404, the processor 41 of the user device 40 transmits to the management device 50 information indicating the projection conditions of the projection material 26 acquired in steps S401 to S403, the number of processed workpieces W, and the initial values of the inventory amount of the projection material 26.
[0125] In step S405, the processor 51 of the management device 50 acquires information indicating the projection conditions of the projection material 26, the number of workpieces W to be processed, and the initial value of the inventory amount of the projection material 26 from the user device 40.
[0126] In step S406, the processor 51 of the management device 50 calculates the required amount of the projection material 26 based on the information indicating the projection conditions of the projection material 26 acquired in step S405, the number of workpieces W to be processed, and the initial value of the inventory amount of the projection material 26.
[0127] In step S407, the processor 51 of the management device 50 performs processing to automatically order the required amount of the projection material 26 calculated in step S406.
[0128] In the fourth embodiment, similarly to the first embodiment, the processor 51 of the management device 50 may notify the user device 40 of information regarding the required amount of projection material 26, instead of automatic ordering processing.
[0129] (Action and effect) As described above, according to the fourth embodiment, the following advantageous effects can be obtained.
[0130] The processor 51 of the management device 50 calculates the required amount of projection material 26 using the number of processed workpieces W instead of the projection time of the projection material 26. When the required amount calculated in this manner is output to a user device 40 installed in the shot processing equipment 10, the user working at the shot processing equipment 10 does not need to check the inventory of the projection material 26 himself, reducing the user's effort in inventory management.
[0131] The processor 51 of the management device 50 may use the number of processed workpieces W instead of the projection time of the projection material 26 when calculating the required amount of each part described in the second embodiment.
[0132] [Software implementation example] The functions of the management device 50 can be realized by a program for causing a computer to function as the management device 50 and a program for causing a computer to function as each control block of the management device 50 .
[0133] In this case, the management device 50 includes a computer having at least one device (e.g., a processor) and at least one storage device (e.g., a memory) as hardware for executing a program. The computer executes the program to realize each function described in each embodiment.
[0134] The program may be recorded in one or more computer-readable recording media, not temporarily. The recording media may or may not be included in the management device 50. In the latter case, the program may be supplied to the management device 50 via any wired or wireless transmission medium.
[0135] In addition, some or all of the functions of each control block can be realized by a logic circuit. For example, an integrated circuit in which a logic circuit that functions as each control block is formed is also included in the scope of the present disclosure. In addition, the functions of each control block can be realized by, for example, a quantum computer.
[0136] Furthermore, each process described in each embodiment may be executed by AI (Artificial Intelligence). In this case, the AI may be operated on the management device 50 or may be operated on another device (for example, an edge computer or a cloud server).
