Description

Tool Management Methods in Machine Tool Magazine

[0001] The present invention relates to a tool management method of a machine tool magazine, and more specifically, to a storage management method in a tool magazine according to tool diameter.

[0002] Typically, a compound machine tool is equipped with a tool magazine that stores a variety of tools, and the tool magazine is equipped with a tool port that provides the necessary tools to the spindle according to the control device's instructions and returns the used tools from the spindle.

[0003] Tool ports in a tool magazine are arranged in a continuous pattern at regular intervals. However, tools stored in tool ports vary in diameter depending on their intended use. In some cases, some tools have diameters or widths that interfere with tools stored in adjacent tool ports.

[0004] In this way, in the tool management system of a conventional tool magazine, when storing a large-diameter tool that has a diameter that may cause interference with a tool adjacent to the tool port, the tool is stored only after checking whether the adjacent tool port is empty.

[0005] To this end, in the existing tool management system, as shown in Fig. 5, after checking whether there are empty tool ports on the left and right of the tool port where the large-diameter tool is to be stored in the display unit (50) to the extent that interference does not occur, the tool is stored in a manner such that the large-diameter tool is stored, and after storing the large-diameter tool, the tool ports on the left and right that may cause interference are left empty or set to unusable.

[0006] Therefore, in the conventional tool management system, when a worker stores a large-diameter tool, he or she must check the location of the tool port that can be stored one by one, and after storing the tool, he or she must set the adjacent tool port so that it cannot be used because it may cause interference, which is cumbersome. In addition, when a worker stores a large-diameter tool in a tool magazine, he or she cannot easily visually recognize the storage status of the tool in the tool management system, so he or she must go back and forth between the tool magazine that stores the tool and the tool management system to store the large-diameter tool, which takes excessive work time and causes inconvenience in the work.

[0007] Additionally, if the worker incorrectly selects the location of the tool port to be stored, the tool or tool magazine may be damaged due to collision of the tool during the tool storage process.

[0008] Meanwhile, Patent Document 1 (Korean Patent No. 10-1203822) comprises a detection unit that identifies the port number of an operating magazine, an operation unit configured to input the number of a tool or port, a first control unit that calculates data based on a signal transmitted from the operation unit and issues a control command, a second control unit configured as a multi-management system to control data calculation processing and signal input / output to the first control unit, and a display unit that displays the control result according to the control command of the first and second control units, thereby enabling direct input through a tool data input device installed near the tool magazine, thereby preventing mistakes in inputting data regarding tools and increasing work efficiency.

[0009] In addition, Patent Document 2 (Korean Patent No. 10-0761204) provides a tool display device for a machine tool in which multiple port numbers and multiple tool numbers are displayed, wherein a holder input unit for inputting the presence or absence of a holder by designating one of the multiple port numbers, a holder icon display means for displaying the presence or absence of a holder in the corresponding port number according to the input status of the holder input unit, a weight tool input unit for inputting that it is a weight tool by designating one of the multiple port numbers, and a weight tool icon display means for displaying the presence or absence of a weight tool in the corresponding port number according to the input status of the weight tool input unit.

[0010] Patent document 2 of this kind enables the presence or absence of a holder and a heavy tool to be displayed on the monitor screen for the port number of the tool, thereby preventing collisions or safety accidents that may occur during use.

[0011] However, the above patent documents 1 and 2 do not present a solution for increasing the intuitiveness of tool storage management for large-diameter tools through visualization or for automatically determining whether storage is possible.

[0012] [Prior Art Literature]

[0013] [Patent Document]

[0014] (Patent Document 1) Korean Patent No. 10-1203822

[0015] (Patent Document 2) Korean Patent No. 10-0761204

[0016] The purpose of the present invention to solve the above-mentioned problems is to provide a tool management system that can intuitively identify the position of a tool port that can be stored when storing a tool in a tool port of a tool magazine in a tool management method of a machine tool magazine, thereby storing a tool in a tool port of a tool magazine quickly and accurately without causing interference with adjacent tools.

[0017] In addition, another object of the present invention is to automatically find a tool port location where a large-diameter tool can be stored when stored in a tool port of a tool magazine.

[0018] The tool management method of the machine tool magazine of the present invention to solve the above problems is as follows:

[0019] Tool information input step (S10) for inputting tool information including the tool port unique number of the tool to be stored in the tool port of the tool magazine and the diameter or left-right width of the tool;

[0020] A tool port gap summing step (S20) for determining whether a tool is stored in a tool port on the left and right based on the tool port in which the tool is to be stored, and if the tool is not stored in an empty tool port, summing the gaps between the empty tool ports on the left and right (Ln, Rn) respectively;

[0021] In the tool information input step (S10), if the tool area in the left and right directions of the tool to be stored, calculated based on the radius or left and right width of the tool to be stored, is included in the range of the gap (Ln, Rn) of the empty tool ports on the left and right sides calculated in the tool port gap summation step (S20), it is determined that no interference occurs when the tool is stored in the corresponding tool port, and in the tool interference confirmation step (S30), if the tool area in the left or right direction of the tool to be stored is not included in the range of the gap (Ln, Rn) of the empty tool ports on the left and right sides calculated in the tool port gap summation step (S20), it is determined that interference occurs when the tool is stored in the corresponding tool port;

[0022] In the tool interference confirmation step (S30), if it is determined that the tool area of ​​the tool to be stored does not interfere, a tool storage display step (S40) is included to display the tool area together with the tool mark on the corresponding tool port of the display unit.

[0023] In a preferred embodiment, in the tool information input step (S10) of the tool management method of a machine tool magazine, the input of the unique number of the tool port of the tool to be stored is characterized in that an empty tool port is automatically allocated and input so that the tool area calculated by the diameter or left-right width of the tool to be stored can be stored without interference with the tool area of ​​a previously stored tool.

[0024] In a preferred embodiment, in the tool port interval summation step (S20) of the tool management method of a machine tool magazine, the summation of the empty tool port intervals (Ln, Rn) on the left and right is characterized by calculating the number of consecutive empty tool ports on the left and right by multiplying each by one tool port interval.

[0025] In a preferred embodiment, the tool interference confirmation step (S30) of the tool management method of a machine tool magazine is characterized in that it is determined by the following formula conditions, and if both formulas 1 and 2 are satisfied, it is determined that interference does not occur when a tool to be stored in the corresponding tool port is stored, and if either of formulas 1 and 2 is not satisfied, it is determined that interference occurs when a tool to be stored in the corresponding tool port is stored.

[0026] <Formula 1>

[0027] Right radius (R) of the tool to be stored + left radius (r) of the tool stored in the closest tool port on the right < (sum of the right spacing of the tool ports to be stored (Rn))

[0028] <Formula 2>

[0029] Left radius (R) of the tool to be stored + right radius (r) of the tool stored in the leftmost adjacent tool port < (sum of the left spacing of the tool ports to be stored (Ln))

[0030] In a preferred embodiment, in the tool management method of a machine tool magazine, in the tool interference confirmation step (S30), if it is determined that interference occurs when a tool is stored in the corresponding tool port, a message or alarm indicating that the tool cannot be stored in the tool port is output on the display unit in the tool storage display step (S40).

[0031] In a preferred embodiment, after outputting the above message or alarm of the tool management method of the machine tool magazine, the tool storage process is terminated or the tool port unique number is re-entered to return to the tool information input step (S10).

[0032] In a preferred embodiment, in the tool storage display step (S40) of the tool management method of a machine tool magazine, the tool area displayed on the display unit is characterized in that it is identifiable by the size of the diameter or left-right width of the tool stored in the tool port.

[0033] The tool management method of the machine tool magazine of the present invention displays, through a display unit, whether a tool is stored in each tool port and the left and right directions of the stored tools as tool areas including the size of the adjacent tool ports, so that when a worker attempts to store a new tool in the tool port of the tool magazine, he or she can intuitively recognize the status of the already stored tools and the stored tool areas, thereby quickly and accurately storing the tool in the tool port of the tool magazine without causing interference with the already stored tools.

[0034] In addition, if a tool to be stored interferes with a tool already stored, an alarm or message is displayed through the display unit to cause the operator to stop storing the tool, thereby preventing damage to the tool magazine or tool due to an error in storing the tool, and preventing unnecessary actions by the operator, thereby promoting safety and convenience in tool storage management.

[0035] In addition, the tool management method of the machine tool magazine of the present invention can automatically find the tool port location of a retractable large-diameter tool without the operator having to individually check the retractable tool port location when retracting a large-diameter tool.

[0036] FIG. 1 is a block diagram of a tool magazine control device as an embodiment of the present invention.

[0037] Fig. 2 is an exemplary diagram of a display unit of a tool magazine control device as an embodiment of the present invention.

[0038] FIG. 3 is a flow chart of a large-diameter tool management of a tool magazine control device as an embodiment of the present invention.

[0039] FIG. 4 is a conceptual diagram of the tool diameter and tool port spacing in a tool magazine control device as an embodiment of the present invention.

[0040] Fig. 5 is an example of a display unit of a tool magazine control device as an embodiment of the prior art.

[0041] Hereinafter, a preferred embodiment of the present invention will be described with reference to FIGS. 1 to 4.

[0042] First, referring to FIG. 1, the tool magazine control device (10) is equipped with an information storage unit (20) that records information about a tool (11) to be stored in the tool port (12) of the tool magazine.

[0043] The above information storage unit (20) is composed of a tool port information storage unit (21) that records a unique number corresponding to the position of the tool port (12) and the distance from the adjacent tool port (12), and a tool information storage unit (22) that records the diameter or left-right width of the tool (11), weight, length, type of tool (11), etc.

[0044] In addition, the tool magazine control device (10) has an information input unit (30) that inputs information about the tool port (12) and the tool (11) into the tool port information storage unit (21) and the tool information storage unit (22).

[0045] In addition, when information on the tool port (12) and the tool (11) is input from the information input unit (30), the tool magazine control device (10) is provided with a calculation unit (40) that calculates a tool area (52) corresponding to the size in the left and right directions based on the radius or left and right width of the tool (11), and also adds up the intervals (Ln, Rn) of consecutive empty tool ports (12) in the left and right directions based on the designated tool port (12), and determines whether the tool area (52) is included in the range of the intervals (Ln, Rn) of the empty tool ports (12) on the left and right sides that are added up.

[0046] In addition, the operation unit (40) displays a message or alarm indicating that the tool (11) cannot be stored in the corresponding tool port (12) if the newly stored tool (11) interferes with the tool area (52) of the already stored tool (11).

[0047] Meanwhile, in another embodiment, the information input unit (30) does not input a unique number corresponding to the position of the tool port (12) where the new tool (11) is to be stored, but only inputs the diameter or the width in the left-right direction of the tool (11), and the calculation unit (40) calculates the tool area (52) based on the diameter or the width in the left-right direction of the newly stored tool (11), and compares the calculated tool area (52) with the tool area (52) of the previously stored tool (11), so that an empty tool port (12) in which the newly stored tool (11) can be stored without interference with the tool area (52) of the previously stored tool (11) can be automatically allocated.

[0048] Therefore, the worker only needs to store the new tool (11) in the tool port (12) of the shared number assigned to the newly stored tool (11).

[0049] Meanwhile, the tool magazine control device (10) displays the position of the tool port (12) of the tool magazine, and is equipped with a tool mark (51) indicating that the tool (11) is stored in the tool port (12) in which the tool (11) is stored, and a display unit (50) displaying the tool area (52) of the corresponding tool (11) calculated by the calculation unit (40).

[0050] In addition, if a tool (11) is already stored in the tool port (12) to be newly stored or if the tool area (52) of the tool (11) to be stored interferes with the tool area (52) of the tool (11) stored in the adjacent tool port (12), the operation unit (40) displays a message or alarm on the display unit (50) indicating that the tool (11) cannot be stored in the tool port (12).

[0051] Referring to FIG. 2, the display unit (50) displays the tool ports (12) installed in the tool magazine along with their unique numbers on the display screen, and for each tool port (12), whether a tool (11) is stored is displayed along with a tool mark (51) of the tool shape, and a tool area (52) calculated based on information about the diameter or left-right width of the stored tool (11).

[0052] At this time, the size of the tool area (52) displayed in the corresponding tool port (12) of the display unit (50) is the diameter or left-right size of the tool (11), and is displayed as an image that can be identified from the surrounding images.

[0053] Accordingly, the display unit (50) displays whether a tool (11) is stored in each tool port (12) and the left and right directions of the stored tool (11) as a tool area (52). At this time, the tool area (52) is displayed to exceed the adjacent tool port (12) according to its size, thereby allowing the worker to intuitively recognize the size of the tool (11) stored in the tool port (12) of the tool magazine and the tool port (12) that can store the tool (11) and the tool port (12) that cannot store the tool.

[0054] Meanwhile, the tool magazine control device (10) internally displays an alarm or message through the display unit (50) to not allow the tool (11) to be stored in a tool port (12) in which a tool area (52) is already displayed based on the calculation result of the calculation unit (40), and when the tool port (12) in which the tool (11) is to be stored is empty, the control device controls the storage of only tools (11) of a size in which the tool areas (52) of the tools (11) stored in the adjacent tool port (12) do not interfere with each other even in part.

[0055]

[0056] Hereinafter, a tool management method of a tool magazine control device (10) will be described with reference to FIGS. 3 and 4.

[0057] First, execute the tool information input step (S10).

[0058] This step is a step for entering information about a tool (11) to be stored in a tool port (12) of a tool magazine. Information such as the unique number of the tool port (12) in which the tool (11) is to be stored, the diameter or left-right width of the tool (11), weight, length, and type of the tool (11), which is entered through the information input unit (30), is stored in the information storage unit (20).

[0059] At this time, among the information input through the information input unit (30), the unique number of the tool port (12) and the distance between adjacent tool ports (12) are stored in the tool port information storage unit (21), and information such as the diameter or left-right width of the tool (11), weight, length, and type of tool (11) are stored in the tool information storage unit (22).

[0060] In addition, the tool information storage unit (22) calculates and stores a tool area (52) corresponding to the size of the left and right directions of the tool (11) to be stored based on the radius or left and right width of the tool (11).

[0061] At this time, the tool area (52) is calculated based on the diameter of the tool (11) in the case of a circular tool (11) with the same width in the left and right directions, and in the case of different widths in the left and right directions, the tool area (52) is calculated based on the widths in each left and right direction.

[0062] In this way, the information on the tool port (12) and tool (11) recorded in the information storage unit (20) is stored in the form of a database and can be assigned as information on the tool (11) and tool port (12) to be selected and stored when storing the tool (11) later.

[0063] Meanwhile, in another embodiment, among the information on the tool port (12) and the tool (11) input through the information input unit (30) in the tool information input step (S10), the unique number of the tool port (12) for storing the tool (11) may not be input, and the tool area (52) calculated by the diameter or left-right width of the newly stored tool (11) may be compared with the tool port (12) and tool area (52) of the previously stored tool (11), so that an empty tool port (12) in which the newly stored tool (11) can be stored without interference with the tool area (52) of the previously stored tool (11) may be automatically allocated.

[0064] Therefore, the worker does not need to specify the tool port (12) of the newly stored tool (11) in the tool information input step (S10), but can use the unique number of the automatically assigned tool port (12).

[0065]

[0066] Next, the tool port interval summation step (S20) is executed.

[0067] As illustrated in Fig. 4, this step determines whether the tool (11) is stored in the tool port (12) on the left and right sides of the tool port (12) in which the tool (11) is to be stored, based on the tool (11) and tool port (12) input in the tool information input step (S10), and if the tool port (12) is empty and the tool (11) is not stored, the gaps (Ln, Rn) between the empty tool ports on the left and right are added up.

[0068] That is, when empty tool ports (12) on the left and right exist consecutively, the intervals (Ln, Rn) of all consecutive empty tool ports (12) are each added up.

[0069] At this time, the sum of the empty tool port spacing (Ln, Rn) on the left and right is calculated by counting the number of empty tool ports (12) consecutive to the left and right based on the input or selected tool port (12) and multiplying it by one tool port spacing (Ln or Rn) applied in the same manner.

[0070] Meanwhile, when adding up the empty tool port intervals (Ln, Rn), if there is a tool port (12) in which a tool (11) is stored in the left and right directions of the input or selected tool port (12), the addition of the empty tool port intervals (Ln, Rn) is terminated.

[0071]

[0072] Next, the tool interference check step (S30) is executed.

[0073] This step determines whether the tool area (52) of the tool (11) to be stored calculated in the tool information input step (S10) is included within the sum of the spacing (Ln, Rn) of the empty tool ports (12) on the left and right sides calculated in the tool port spacing summation step (S20), i.e., whether the tool (11) to be stored interferes with an adjacent tool (11) that was previously stored.

[0074] At this time, whether the tool (11) to be stored interferes with the adjacent tool (11) can be judged by the following formula conditions.

[0075] <Formula 1>

[0076] Right radius (R) of the tool (11) to be stored + left radius (r) of the tool (11) stored in the closest tool port (12) on the right < (sum of the right spacing of the tool port (12) to be stored (Rn)

[0077] <Formula 2>

[0078] Left radius (R) of the tool (11) to be stored + right radius (r) of the tool (11) stored in the leftmost adjacent tool port (12) < (sum of the left spacing of the tool port (12) to be stored (Ln)

[0079] If both of the above formulas 1 and 2 are satisfied, it is determined that interference does not occur when the tool (11) is stored in the corresponding tool port (12), and if either of the above formulas 1 and 2 is not satisfied, it is determined that interference occurs when the tool (11) is stored in the corresponding tool port (12).

[0080] That is, when the tool area (52) of the tool (11) to be stored in the tool port (12) falls within the sum of the spacing (Ln, Rn) of the empty tool ports (12) in the left and right directions, it is determined that the tool (11) to be stored does not interfere with the tool (11) stored in the most adjacent tool port (12) on the left or right.

[0081] Next, the tool storage display step (S40) is executed.

[0082] In this step, if the tool area (52) of the tool (11) to be stored in the tool interference check step (S30) falls within the sum of the spacing (Ln, Rn) of the empty tool ports (12) in the left and right directions, i.e., if it is determined that the tool (11) to be stored does not interfere with the tool (11) stored in the most adjacent tool port (12) on the left or right, the tool (11) information is stored in the tool information storage unit (22) together with the unique number of the corresponding tool port (12), and the tool area (52) is displayed along with the tool mark (51) on the corresponding tool port (12) of the display unit (50) according to the left and right width of the tool (11) input in the tool information input step (S10). After this, the tool (11) is stored in the tool port (12) of the tool magazine, and the tool (11) storage process is terminated.

[0083] At this time, the display of the tool area (52) on the display unit (50) outputs a tool mark (51) in the shape of a tool (11) at the unique number location of the corresponding tool port (12) of the display unit (50), as shown in FIG. 2, and at the same time, displays the diameter or left-right width of the tool (11) stored in the tool port (12) as the size of the tool area (52).

[0084] On the other hand, if the tool area (52) of the tool (11) to be stored does not fall within the combined range of the spacing (Ln, Rn) of the empty tool ports (12) in the left and right directions and overlaps even a part of them, it is determined that the tool (11) to be stored interferes with the tool (11) stored in the most adjacent tool port (12) on the left or right, and a message or alarm is output on the display unit (50) indicating that the tool (11) cannot be stored in the tool port (12).

[0085] At this time, after outputting a message or alarm, the tool (11) storage process can be terminated or the tool port (12) unique number can be re-entered to return to the tool information input step (S10).

[0086]

[0087] In this way, the tool management method of the machine tool magazine of the present invention displays whether a tool (11) is stored in each tool port (12) and the left and right directions of the stored tools (11) including the size of the adjacent tool ports (12) as a tool area (52) through a display unit (50), so that when a worker wants to store a new tool (11) in the tool port (12) of the tool magazine, the worker can intuitively recognize the status of the already stored tools (11) and the stored tool area (52), so that the tool (11) can be quickly and accurately stored in the tool port (12) of the tool magazine without causing interference with the already stored tools (11).

[0088] In addition, when a tool (11) to be stored interferes with a tool (11) that has already been stored, an alarm or message is displayed through the display unit (50) to cause the worker to stop storing the tool (11), thereby preventing damage to the tool magazine or the tool (11) due to an error in storing the tool (11), and preventing unnecessary actions of the worker, thereby promoting safety and convenience in tool (11) storage management.

[0089] In addition, the tool management method of the machine tool magazine of the present invention can automatically find the tool port (12) location of a retractable large-diameter tool (11) without the operator having to individually check the location of the retractable tool (11) port when retracting a large-diameter tool (11).
