Description

The present invention relates to a material management system.

Conventionally, a processing system has been known that includes a laser processing machine that performs laser processing on materials placed on a pallet, a storage shelf that stores multiple pallets, and a pallet loading/unloading device that is configured to transport the pallets between the laser processing machine and the storage shelf (Patent Document 1, etc.).

In the pallet loading/unloading device of Patent Document 1, a lifter is provided on each side of the storage shelf, and while one lifter is used to load a pallet into the laser processing machine, the other lifter is used to remove the pallet containing the processed product, allowing the product to be collected or materials to be prepared for the next processing step to be prepared.

Japanese Patent Application Publication No. 5-139512

In the processing system of Patent Document 1, once a pallet containing materials is stored in a storage shelf, it is difficult to easily determine which material is placed on which pallet in the storage shelf. For this reason, the processing system of Patent Document 1 requires an operator to travel to the material's position on the storage shelf and visually check the material before processing, which creates the problem of cumbersome work.

In this regard, in the processing system of Patent Document 1, by manually inputting information about materials when storing pallets on a storage shelf, it may be possible to manage which materials are placed on which pallets in the storage shelf. However, the method of manually inputting material information has the problem that work efficiency is poor and the work is cumbersome. Furthermore, when materials are frequently transferred to and from pallets, the deterioration of work efficiency is particularly noticeable, and there is a possibility that information will not be intentionally input or information will be unintentionally omitted, resulting in discrepancies between the actual materials and the input information. For this reason, there remains the problem that a worker must travel to the material position on the storage shelf before processing and visually check the material, making the work cumbersome.

One aspect of the present invention is a material management system that allows materials stored in a storage shelf to be viewed through images.

A material management system according to one aspect of the present invention includes a processing machine for processing materials, a storage shelf including a plurality of storage units capable of storing the materials, a camera for photographing the materials, a memory unit for storing image data of the materials photographed by the camera in association with the storage unit in which the materials are stored, and a display unit for displaying the corresponding image data for each storage unit.

According to the material management system according to one aspect of the present invention, the image data of the material captured by the camera is displayed on the display unit in association with the storage section of the storage shelf in which the material is stored. This allows the material stored in the storage shelf to be confirmed by image.

According to one aspect of the present invention, the material management system allows the materials stored in the storage shelves to be viewed in images.

The laser processing machine 10 is not limited to the above-mentioned configuration, and can have a variety of configurations. Furthermore, the material management system 1 according to this embodiment is not limited to a configuration in which material is processed by the laser processing machine 10, and can use various processing machines such as a so-called turret punch press, milling machine, cutting torch, etc.

[Camera configuration]
As shown in Figs. 1 and 2, the camera 30 is attached to the inside of the laser processing machine 10, for example, to the ceiling inside the housing 11 of the laser processing machine 10, and is configured to be able to photograph the materials W on the pallet P supported by the pallet support part 14. The camera 30 includes an imaging unit 32 and a lens 34. The imaging unit 32 has an imaging element (not shown) and a shutter (not shown), and is configured to be able to transfer the photographed image data to the operation panel 200. In addition, the lens 34 has an angle of view that can photograph the entire pallet P supported by the pallet support part 14 of the laser processing machine 10. With this configuration, the camera 30 is able to photograph all of the materials W when a plurality of materials W are placed on the pallet P supported by the pallet support part 14 of the laser processing machine 10.

[Storage Shelf Configuration]
As shown in Fig. 1, the storage shelf 100 has a rectangular main body frame 101 as a base, which extends along the longitudinal direction (z-axis direction) of the support table 12 of the laser processing machine 10. The main body frame 101 is provided with a number of storage sections 110 (110a to 110k) capable of storing pallets P on which materials W are placed. An elevator 120 is provided on the side of the main body frame 101. The elevator 120 is configured to be able to rise and fall in the y-axis direction by being driven by an elevator drive section (not shown). The elevator 120 also has a pair of support guides 122 that support the pallet P so that it can move in the x-axis direction.

The storage shelf 100 is further provided with a traverser 130 for transporting the pallet P between a pair of support guides 122 of the elevator 120 and any storage section 110, and between a pair of support guides 122 of the elevator 120 and the pallet support section 14. The traverser 130 can move in the x-axis direction on the support guides 122 and on the pallet support section 14 by being driven by a traverser drive section (not shown).

[Operation panel configuration]
FIG. 3 is a functional block diagram that illustrates the material management system of the present embodiment.
As shown in Figure 3, the operation panel 200 generally includes a main control unit 210 for controlling the laser processing machine 10 and the storage shelf 100, a memory unit 220 for storing image data of the material W captured by the camera 30 in correspondence with the storage unit 110 in which the material W is stored, an input unit 230 for accepting operation instructions from a user (operator), and a display unit 240 capable of displaying various information including image data.

The storage unit 220 includes a program 222 and an image management ledger 224, and is configured with a storage medium such as a RAM, ROM, HDD, SSD, etc., and stores processing programs, image data, etc. in a readable and writable manner. The program 222 has a processing program for operating the laser processing machine 10 and processing the material W, a transport program for transporting the pallet P, a photography program for the camera 30, an image correction program for correcting the image data photographed by the camera 30, and an operating system for the operation panel 200. The processing program has laser processing conditions including plate thickness information, and a tool path.

Fig. 5 is a diagram for explaining the state of image data captured by the camera of this embodiment before correction. Fig. 6 is a diagram for explaining the state of image data captured by the camera of this embodiment after correction.
An image correction program for correcting image data captured by the camera 30 will be described with reference to Figures 5 and 6. As described above, the camera 30 attached to the ceiling of the laser processing machine 10 includes a lens 34 having an angle of view capable of capturing an image of the entire pallet P supported by the pallet support part 14 of the laser processing machine 10. Therefore, the image captured by the camera 30 is distorted so that the center of the image bulges, as shown in Figure 5, and distortion aberration occurs in which what should be a rectangular shape becomes barrel-shaped.

Furthermore, since the shooting position and focal length of the camera 30 are always constant, even when a material W having the same surface area is photographed, the surface area of the material W that occupies the angle of view changes depending on the plate thickness of the material W.

For example, when the camera 30 photographs a rectangular material _W1 having a thickness of 1 mm and a rectangular material W5 having a thickness of ₅ mm, the distance between the surface of the material and the image sensor (not shown) of the camera 30 is closer for the rectangular material _W5 having a thickness of 5 mm and farther for the rectangular material _W1 having a thickness of 1 mm. Therefore, the surface area of the material occupying the angle of view of the photographed image data is larger for the rectangular material W5 having a thickness of 5 mm than for the rectangular material _W1 having _a thickness of 1 mm. If the material W is not displayed at the correct size within the angle of view, the end face correction cannot be performed accurately. Therefore, as shown in FIG. 6, the image data is subjected to distortion correction and plate thickness correction using plate thickness information.

The image correction program stored in the memory unit 220 is configured to be able to execute distortion correction and plate thickness correction to correct the above-mentioned distortions. The plate thickness information used for plate thickness correction may be plate thickness information contained in the processing program used after photographing, or plate thickness information set in the program when the photographed material W is actually processed. In the latter case, the image data and plate thickness information are associated and stored in the image management ledger 224 of the memory unit 220. Plate thickness information manually input into the image management ledger 224 of the memory unit 220 described later may also be used.

FIG. 4 is a diagram showing an example of the image management register of this embodiment.
4, the image management ledger 224 has a storage section memory area 224a for registering information relating to the storage section 110a on the top level of the storage shelf 100, a storage section memory area 224b for registering information relating to the storage section 110b on the level below the storage section 110a (the second level from the top of the storage shelf 100), and similarly, storage section memory areas 224c to 224k for registering information relating to the storage sections 110c to 110k of the storage shelf 100. The storage section memory areas 224a to 224k store image data of the material W photographed by the camera 30, the photographing date and time of the image data, and the storage section 110 of the storage shelf 100 in which the pallet P on which the material W is placed is stored, in association with each other.

In addition, the storage section memory areas 224a to 224k of the image management ledger 224 can be further associated with information (not shown) about the material W stored in the storage section 110 of the storage shelf 100 by the user manually inputting the information. Examples of the information about the material W stored in the storage section 110 of the storage shelf 100 include the material quality, thickness, and dimensions of the material W.

As shown in FIG. 3, the main control unit 210 functionally includes an operation management unit 212, a shelf management unit 214, a program management unit 216, and an image management unit 218, and is configured, for example, by an integrated processing device having a CPU and a GPU. The operation management unit 212 is configured to be capable of controlling the operation of the laser processing machine 10 according to a processing program stored in the memory unit 220 of the operation panel 200. The operation management unit 212 is also configured to be capable of controlling the camera 30 according to an imaging program stored in the memory unit 220 of the operation panel 200.

The shelf management unit 214 is capable of operating the storage section 110, elevator 120, and traverser 130 of the storage shelf 100, and is configured to transport the pallet P between the laser processing machine 10 and the storage shelf 100. The program management unit 216 manages the processing program for processing the material W by the laser processing machine 10, and is configured to be able to edit the processing program. The program management unit 216 is also configured to be able to detect the end face position and correct the end face of the processing program.

The image management unit 218 manages the image management ledger 224 of the memory unit 220. Specifically, the image management unit 218 performs processes such as registering image data transferred from the camera 30 in the image management ledger 224 of the memory unit 220 in association with the date and time the image data was taken and the storage unit 110 of the storage shelf 100 in which the material W is stored, reading out and correcting image data from the image management ledger 224 of the memory unit 220, and displaying the image data on the display unit 240. In addition, when the image data registered in the image management ledger 224 of the memory unit 220 in association with each storage unit 110 of the storage shelf 100 is outdated, the image data can be deleted or updated.

Furthermore, the image management unit 218 is configured not to overwrite and save the original image data when reading out image data from the image management ledger 224 of the storage unit 220 and correcting the image data according to the image correction program. With this configuration, the image management unit 218 can display image data corrected according to the multiple plate thicknesses on the display unit 240 when the image data shows multiple materials W with different plate thicknesses.

The input unit 230 is composed of input devices such as push button switches, tact switches, key lock switches, keyboards, etc., and by operating the input unit 230, operations such as selecting the machining program to be used for machining can be performed.

The display unit 240 displays various screens such as a selection screen for selecting the processing program to be used for processing and the storage section 110 of the storage shelf 100 in which the material W to be used for processing is stored, and captured image data. The display unit 240 is also configured with a touch panel (Touch screen) having an input function, and is configured to be able to accept input operations of the measurement points for end face position detection, which will be described later. With such a configuration, the user can, for example, operate the display unit 240 to select the processing program to be used for processing, or specify the measurement start position of the measurement points for end face position detection, which will be described later.

FIG. 7 is a diagram for explaining the end face position detection of this embodiment.
The detection of the end face position and the correction of the processing program will be described with reference to Fig. 7. When the material W is placed on the pallet P so that the end face (end) of the material W is parallel to the end face of the pallet P, the end faces of the material W and the pallet P are parallel to the X-axis and Y-axis along which the laser processing head 20 of the laser processing machine 10 moves along the tool path of the processing program, so that the material W can be normally laser processed without correcting the processing program.

On the other hand, if the material W is placed on the pallet P so that the end face of the material W is oblique to the end face of the pallet P, the end face of the material W is not parallel to the X-axis and Y-axis along which the laser processing head 20 of the laser processing machine 10 moves along the tool path of the processing program. If laser processing is performed in this state without correcting the processing program, a deviation will occur between the tool path and the position where the material W is placed, resulting in processing defects. In order to prevent such processing defects, the end face position is detected and the processing program is corrected.

Specifically, first, three measurement points are set and the end face of the material W is measured to detect the end face position. Then, the machining origin of the machining program and the angle of the tool path are corrected based on the detected end face position (end face correction). Here, the display unit 240 of the operation panel 200 is configured to be able to display information related to end face position detection, and further, the display unit 240 of the operation panel 200 is configured to be able to display the measurement points of the end face position detection on the image data. With such a configuration, as shown in FIG. 7, the user can check the image data of the material W stored in the storage unit 110 of the storage shelf 100 on the display unit 240 of the operation panel 200, and further select the measurement pattern of the end face position detection on the image data, and directly specify the measurement start position of the measurement point of the end face position detection by the touch panel.

[Operation of the material management system according to this embodiment]
8 and 9 are flow charts showing an example of a product processing and material management procedure using the material management system of this embodiment.
A series of operations for product processing and material management for unprocessed material W that has never been processed into a product will be described with reference to FIG.

First, the start of the operation panel 200 is used as a trigger to cause the operation management unit 212 of the main control unit 210 of the operation panel 200 to read out the processing program for performing laser processing by the laser processing machine 10 from the memory unit 220 of the operation panel 200 (S1 in FIG. 8). After that, the operation management unit 212 transfers the read processing program to the laser processing machine 10 (S2 in FIG. 8).

The shelf management section 214 of the main control section 210 of the operation panel 200 operates the elevator 120 and traverser 130 etc. equipped on the storage shelf 100 to transport the pallet P on which the material W is placed to the pallet support section 14 of the laser processing machine 10. After the pallet P on which the material W is placed is transported, the carriage base 16 of the laser processing machine 10 moves from the standby position, and the laser processing head 20 moves to the processing origin. The laser processing head 20 of the laser processing machine 10 irradiates the material W on the pallet P supported by the pallet support section 14 of the laser processing machine 10 with laser light, and starts laser processing of the material W along the tool path of the processing program (S3 in FIG. 8).

When the laser processing head 20 of the laser processing machine 10 finishes emitting laser light and the carriage base 16 of the laser processing machine 10 retreats to the standby position, the laser processing by the laser processing machine 10 is completed (S4 in FIG. 8). The laser processing machine 10 notifies the operation management unit 212 of the operation panel 200 that the carriage base 16 of the laser processing machine 10 has retreated and the entire pallet P supported by the pallet support unit 14 of the laser processing machine 10 is now visible on the camera 30 installed on the ceiling of the laser processing machine 10.

Then, the operation management unit 212 of the operation panel 200 reads out the shooting program for the camera 30 from the memory unit 220 of the operation panel 200 and starts the camera 30. The operation management unit 212 controls the camera 30 in accordance with the read out shooting program, and causes the camera 30 to take an image of the entire pallet P supported by the pallet support unit 14 of the laser processing machine 10 (S5 in FIG. 8). The image data taken by the camera 30 is then transferred to the operation panel 200 (S6 in FIG. 8).

The image management unit 218 of the operation panel 200 registers the image data transferred from the camera 30 in the image management ledger 224 of the memory unit 220 of the operation panel 200 (S7 in FIG. 8). When registering the image data, the image management unit 218 of the operation panel 200 also registers the date and time when the image data was captured and the storage unit 110 of the storage shelf 100 in which the pallet P on which the material W is placed is stored, in association with the image data.

The shelf management unit 214 operates the elevator 120 and traverser 130 of the storage shelf 100, and moves the pallet P on which the material W is placed from inside the laser processing machine 10 to the storage section 110 of the storage shelf 100. Specifically, the shelf management unit 214 first transports the pallet P from the pallet support section 14 of the laser processing machine 10 to the support guide 122 of the elevator 120 by the traverser 130 of the storage shelf 100. Next, the shelf management unit 214 raises the pallet P supported by the support guide 122 of the elevator 120 by the elevator 120 of the storage shelf 100 to the position of an empty storage section 110. Then, the storage shelf 100 stores the pallet P by transporting the pallet P supported by the support guide 122 of the elevator 120 to an empty storage section 110 by the traverser 130 (S8 in FIG. 8).

Next, referring to FIG. 9, a series of operations for product processing and material management from the second time onwards for the material W stored in the storage section 110 of the storage shelf 100 will be described. First, the start of the operation panel 200 is used as a trigger, and the operation management section 212 reads out the processing program for performing laser processing by the laser processing machine 10 from the memory section 220 of the operation panel 200 (S10 in FIG. 9).

At the same time as or after the processing program is read out, a selection screen for the pallets P stored in each storage section 110 of the storage shelf 100 is displayed on the display section 240 of the operation panel 200 (S11 in FIG. 9). This selection screen may be displayed automatically on the display section 240 in conjunction with the reading out of the processing program, or may be displayed manually on the display section 240 by the user operating the operation panel 200. When the user selects an arbitrary pallet P (storage section 110a to 110k) on the selection screen (S12 in FIG. 9), the image management section 218 of the main control section 210 of the operation panel 200 checks whether the image data of the material W photographed by the camera 30 is associated with the selected pallet P (storage section 110) and registered in the image management register 224 of the memory section 220.

If the image data is not registered in association with the pallet P stored in the storage unit 110 selected by the user (NO in S13 of FIG. 9), in other words, if material W is not placed (stored) on the pallet P stored in the storage unit 110 of the storage shelf 100, the image management unit 218 causes the display unit 240 of the operation panel 200 to display a message indicating that the image data is not registered or that material W is not placed on the selected pallet P (S15 of FIG. 9). The display unit 240 of the operation panel 200 then returns to the pallet selection screen.

On the other hand, if the image data is registered in association with the pallet P stored in the storage unit 110 selected by the user (YES in S13 of FIG. 9), that is, if the material W is placed (stored) on the pallet P stored in the storage unit 110 of the storage shelf 100, the image management unit 218 reads out the image data from the image management ledger 224 (S14 of FIG. 9).

The image management unit 218 acquires thickness information of the material W from the processing program read by the operation management unit 212 from the memory unit 220 of the operation panel 200 (S16 in FIG. 9). Then, the image data read is corrected based on the acquired thickness information (S17 in FIG. 9), and the image data is displayed on the display unit 240 of the operation panel 200 (S18 in FIG. 9). The user checks the material W on the pallet P using the image data displayed on the display unit 240 of the operation panel 200. If the user does not want to use the confirmed pallet P for laser processing (NO in S19 in FIG. 9), the display unit 240 of the operation panel 200 returns to the pallet selection screen again.

On the other hand, if the user uses the confirmed pallet P for laser processing (YES in S19 in FIG. 9), the program management unit 216 of the main control unit 210 of the operation panel 200 causes the display unit 240 of the operation panel 200 to display information related to end face position detection. As information related to end face position detection, for example, the image data corrected by the image management unit 218 and the measurement pattern are displayed. The user operates the input unit 230 of the operation panel 200 or the display unit 240 configured by the touch panel of the operation panel 200 to specify three measurement start positions of the measurement points for end face position detection on the image data. When the measurement start positions of the measurement points for end face position detection are specified, the program management unit 216 starts end face position detection (S20 in FIG. 9).

The program management unit 216 corrects the machining origin and the tool path angle of the machining program read by the operation management unit 212 according to the detected end face position (S21 in FIG. 9). When the end face correction is complete, the operation management unit 212 transfers the corrected machining program to the laser processing machine 10 (S2 in FIG. 8), and the same procedure as the first product processing and material management is repeated. Through the above steps, a series of operations for product processing and material management are performed by the material management system 1 according to this embodiment.

[Advantages of the material management system according to this embodiment]
As described above, the material management system 1 of this embodiment comprises a laser processing machine 10 (processing machine) that processes material W, a storage shelf 100 including a plurality of storage sections 110 capable of storing material W, a camera 30 for photographing the material W, a memory unit 220 that stores image data of the material W photographed by the camera 30 in correspondence with the storage section 110 in which the material W is stored, and a display unit 240 that displays corresponding image data for each storage section 110.

In addition, in the material management system 1 according to this embodiment, the display unit 240 is configured to be able to display information related to end face position detection together with image data. This configuration has the advantage that end face position detection can be performed while visually checking, referring to the image data of the material W photographed by the camera 30.

Furthermore, in the material management system 1 according to this embodiment, the display unit 240 is configured to be able to display the measurement points for end face position detection on the image data. By providing such a configuration, it has the advantage that the measurement points for end face position detection can be visually confirmed on the image data of the material W photographed by the camera 30.

In addition, in the material management system 1 according to this embodiment, the display unit 240 is configured to be able to accept input operations for the measurement points for end face position detection. This configuration has the advantage that the measurement start position for the measurement points for end face position detection can be intuitively specified on the image data of the material W captured by the camera 30.
