FIG. 36 is a diagram for explaining the positional relationship between the operation panel 6 and the first support section 41 in the height direction. In FIGS. 1 to 36, in order to avoid complication of the drawings, the description of members unnecessary for the explanation is omitted or simplified. Also, the description of the tool T excluding the first tool T1 is simplified.

[0012] As illustrated in FIGS. 1 and 2, the tool storage device 1A includes a magazine 2, a first opening OP1, a first door 31, and a tool temporary placement table 4.

[0013] The magazine 2 stores a plurality of tools T held by a plurality of holding portions HA movable along a first track OB1.

[0014] As illustrated in FIG. 1, the first opening OP1 is formed in the magazine 2. The first opening OP1 allows the first tool T1 to pass through when the first tool T1 is carried into the magazine 2.

[0015] As illustrated in FIGS. 1 and 2, the first door 31 opens and closes the first opening OP1. More specifically, the first door 31 is movable between a first position P1 (see FIG. 2) that closes the first opening OP1 and a second position P2 (see FIG. 1) that opens the first opening OP1.

[0016] As illustrated in FIGS. 1 to 3, the tool temporary placement table 4 has a first support section 41 capable of supporting the first tool T1. As illustrated in FIG. 1, the tool temporary placement table 4 is disposed below the first opening OP1 and is supported by the magazine 2.

[0017] In the first embodiment, the tool temporary placement table 4 is supported by the magazine 2 of the tool storage device 1A. In this case, compared with the case where the tool temporary placement table is arranged at a position away from the magazine 2, tools such as the first tool T1 can be temporarily placed near the magazine 2. Therefore, the moving distance of the operator can be shortened, and the working efficiency of the operator is improved.

[0018] Also, in the first embodiment, the tool temporary placement table 4 is arranged below the first opening OP1 through which tools are taken in and out. In this case, the operator can smoothly perform the operation of taking out the tool from the tool temporary placement table 4 and the operation of carrying the taken-out tool into the magazine 2. Also, the operator can smoothly perform the operation of taking out the tool from the magazine 2 and the operation of temporarily placing the taken-out tool on the tool temporary placement table 4.

[0019] (Optional additional configuration) Subsequently, with reference to FIGS. 1 to 36, optional additional configurations that can be adopted in the first embodiment will be described.

[0020] (Change in the position of the tool temporary placement table 4) In the examples shown in FIGS. 4 and 5, the position of the tool temporary placement table 4 can be changed between a retracted position Q1 (see FIG. 4) where the first support section 41 is stored in the magazine 2 and a use position Q2 (see FIG. 5) where the first support section 41 is exposed from the magazine 2.

[0021] When the position of the tool temporary placement table 4 can be changed between the above-described retracted position Q1 and the above-described use position Q2, the tool temporary placement table 4 does not interfere with the operator when not in use. Also, since the first support section 41 is stored in the magazine 2, there is no need to prepare a storage space for the first support section 41 separately from the magazine 2.

[0022] Alternatively, the tool temporary placement table 4 may always be located at the use position Q2. In other words, the tool temporary placement table 4 may not be storable in the magazine 2.

[0023] (Partition 211a) In the example shown in FIG. 6, the tool storage device 1A includes a second opening OP2 formed in the magazine 2, a second door 33 capable of opening and closing the second opening OP2, and a partition 211a disposed between the first opening OP1 and the second opening OP2. In the example shown in FIG. 7, the second door 33 is movable between a third position P3 for closing the second opening OP2 and a fourth position P4 for opening the second opening OP2.

[0024] In the example shown in FIG. 7, when the tool temporary placement table 4 is in the use position Q2, the first support section 41 is located in front of the partition 211a in a plan view.

[0025] In this case, as illustrated in FIG. 6, since the first support section 41 is disposed at a position close to the first opening OP1 and the second opening OP2, it is easy to carry a tool (e.g., the first tool T1) taken out from the first support section 41 into the magazine 2 through the first opening OP1 or the second opening OP2. Further, since the first tool T1 supported by the first support section 41 does not block the first opening OP1 and the second opening OP2, it is easy to carry out another tool (e.g., the second tool T2) from the magazine 2 through the first opening OP1 or the second opening OP2.

[0026] In the example shown in FIG. 9, the first door 31 located at the second position P2 does not block the region between the first support section 41 and the first opening OP1 in a plan view. Thus, it is easy to carry a tool (e.g., the first tool T1) taken out from the first support section 41 into the magazine 2 through the first opening OP1.

[0027] In the example shown in FIG. 9, the second door 33 located at the fourth position P4 does not block the region between the first support section 41 and the second opening OP2 in a plan view. Thus, it is easy to carry a tool (e.g., the first tool T1) taken out from the first support section 41 into the magazine 2 through the second opening OP2.

[0028] In this specification, the direction in which the tool T is carried out from the magazine 2 through the first opening OP1 (more specifically, the direction from the back surface 23 of the magazine 2 toward the first opening OP1) is defined as the first direction DR1. In the example shown in FIG. 9, when the tool temporary placement table 4 is in the use position Q2, the first support section 41 is in a position overlapping with a straight line LN extending in the first direction DR1 from the partition 211a in a plan view. In other words, the first support section 41 is disposed directly below the space in front of the partition 211a.

[0029] In the example shown in FIG. 8, the operator can perform the operation of taking out the first tool T1 from the tool temporary placement table 4 and the operation of carrying the taken-out first tool T1 into the magazine 2 without moving even one step. Further, the operator can perform the operation of carrying out the second tool T2 from the magazine 2 and the operation of temporarily placing the carried-out second tool T2 on the tool temporary placement table 4 without moving even one step.

[0030] (The first door 31) In the example shown in FIG. 1, the first door 31 can open and close the first opening OP1 that allows access to the first group of holding portions HA (for example, the first holding portion HA1).

[0031] In the example shown in FIG. 7, the outer side portion 311 of the first door 31 is supported by the magazine 2 so as to be rotatable about a first axis AX1 that is substantially parallel to the vertical direction.

[0032] As illustrated in FIG. 7, when the tool temporary placement table 4 is in the use position Q2, the first support section 41 is outside the movement track OE1 of the first door 31 in a plan view. In this case, as illustrated in FIG. 8, even when a tool (for example, the first tool T1) is supported by the first support section 41, the first door 31 moving along the movement track OE1 between the first position P1 and the second position P2 does not interfere with the tool (for example, the first tool T1) supported by the first support section 41. Therefore, the first door 31 can be opened and closed while a tool (for example, the first tool T1) is supported by the first support section 41. In FIG. 7, the movement track OE1 of the first door 31 is visualized by dot hatching.

[0033] In the example shown in FIG. 9, the first door 31 includes an outer side portion 311 supported by the magazine 2 and an inner side portion 313 movable toward the partition 211a.

[0034] In the example shown in FIG. 3, the first door 31 includes a first transparent window 317. When the first door 31 is in the first position P1, the operator can simultaneously visually recognize a plurality of holding portions HA including the first holding portion HA1 through the first transparent window 317. In this case, the operator can check the states of the plurality of holding portions HA (for example, which holding portions are empty or what tools are attached to which holding portions) without opening the first door 31.

[0035] As illustrated in FIG. 3, the first door 31 may include a first handle 319 that can be gripped by the operator.

[0036] In the example shown in FIG. 7, the first door 31 is a swing door that can swing around the first axis AX1. Alternatively, as illustrated in FIG. 11, the first door 31 may be a slide door that can slide along the first guide rail GL1.

[0037] (Second door 33) In the example shown in FIG. 1, the second door 33 can open and close a second opening OP2 that allows access to a second group of holding portions HB (for example, the second holding portion HB1). More specifically, as illustrated in FIG. 7, the second door 33 is movable between a third position P3 that closes the second opening OP2 and a fourth position P4 that opens the second opening OP2.

[0038] In the example shown in FIG. 7, the outer side portion 331 of the second door 33 is supported by the magazine 2 so as to be rotatable around a second axis AX2 that is substantially parallel to the vertical direction.

[0039] As illustrated in FIG. 7, when the tool temporary table 4 is in the use position Q2, the first support section 41 is outside the movement track OE2 of the second door 33 in plan view. In this case, as illustrated in FIG. 8, even when a tool (for example, the first tool T1) is supported by the first support section 41, the second door 33 that moves along the movement track OE2 between the third position P3 and the fourth position P4 does not interfere with the tool (for example, the first tool T1) supported by the first support section 41. Therefore, the second door 33 can be opened and closed while the tool (for example, the first tool T1) is supported by the first support section 41.

[0040] In the example shown in FIG. 9, the second door 33 includes an outer side portion 331 supported by the magazine 2 and an inner side portion 333 movable toward the partition 211a.

[0041] In the example shown in FIG. 3, the second door 33 includes a second transparent window 337. When the second door 33 is in the third position P3, the operator can simultaneously visually recognize a plurality of holding portions HB including the second holding portion HB1 through the second transparent window 337. In this case, the operator can check the states of the plurality of holding portions HB (for example, which holding portion is empty, or what tool is attached to which holding portion) without opening the second door 33.

[0042] As illustrated in FIG. 3, the second door 33 may include a second handle 339 that can be gripped by the operator.

[0043] In the example shown in FIG. 7, the second door 33 is a swing door that can swing around the second axis AX2. Alternatively, as illustrated in FIG. 11, the second door 33 may be a slide door that can slide along the second guide rail GL2.

[0044] (First region RG1 and second region RG2) In the example shown in FIG. 6, the magazine 2 defines a first region RG1 that stores a first group of tools held by a first group of holding parts HA movable along a first track OB1, and a second region RG2 that stores a second group of tools held by a second group of holding parts HB movable along a second track OB2. In the example shown in FIG. 6, the second region RG2 is arranged side by side in the lateral direction of the first region RG1.

[0045] (Storage shelf 90) Alternatively, or additionally, as illustrated in FIG. 12, the magazine 2 may define a first region RG1 that stores a first group of tools held by a first group of holding parts HA movable along a first track OB1, and a storage shelf 90. In the example shown in FIG. 12, the storage shelf 90 is arranged side by side in the lateral direction of the first region RG1.

[0046] In the example shown in FIG. 12, the tool storage device 1A includes a second opening OP2 formed in the magazine 2, a second door 33 capable of opening and closing the second opening OP2, and a partition 211a disposed between the first opening OP1 and the second opening OP2. Since the second opening OP2, the second door 33, and the partition 211a have been described, repeated descriptions of these configurations are omitted.

[0047] In the example shown in FIG. 12, the operator can access the articles (for example, tool tips) stored in the storage shelf 90 through the second opening OP2. As illustrated in FIG. 12, the storage shelf 90 may include a plurality of shelf boards 91 including a first shelf board 91a and a second shelf board 91b. When the second door 33 is in the fourth position P4 (in other words, the open position), the operator can access the first storage space above the first shelf board 91a and the second storage space above the second shelf board 91b. On the other hand, when the second door 33 is in the third position P3 (in other words, the closed position), access by the operator to the first storage space above the first shelf board 91a and the second storage space above the second shelf board 91b is prohibited.

[0048] Alternatively, as illustrated in FIG. 13, the second region RG2 (see FIG. 6) and the storage shelf 90 (see FIG. 12) may be omitted.

[0049] (Arrangement of the first support section 41) In the example described in FIGS. 7 and 14, when the tool rest 4 is in the use position Q2, the first support section 41 is outside the movement track OE1 of the first door 31 in plan view.

[0050] In the examples described in FIGS. 6, 12, and 13, the magazine 2 includes a first wall 211 that defines one side of the first opening OP1 described above. In the examples described in FIGS. 6 and 12, the first wall 211 is a partition 211a disposed between the first opening OP1 and the second opening OP2.

[0051] In the examples described in FIGS. 10, 11, and 15, the position of the tool rest 4 can be changed between a retracted position Q1 where the first support section 41 is stored in the magazine 2 and a use position Q2 where the first support section 41 is exposed from the magazine 2.

[0052] In the example described in FIG. 16, the first support section 41 includes a first pocket 41p that supports the shank of the tool (e.g., the shank Ts of the first tool T1) from below. As illustrated in FIG. 16, the tool (e.g., the first tool T1) may include a tool body Tm and a tool holder Th that holds the tool body Tm.

[0053] In the examples described in FIGS. 9 and 14, when the tool rest 4 is in the use position Q2, the first support section 41 (more specifically, the first pocket 41p) is located in front of the first wall 211 (e.g., the partition 211a) in plan view. More specifically, when the tool rest 4 is in the use position Q2, the first support section 41 (more specifically, the first pocket 41p) is in a position overlapping a straight line LN extending in the first direction DR1 from the first wall 211 (e.g., the partition 211a) in plan view.

[0054] In this case, as illustrated in FIGS. 6, 12, and 13, since the first support section 41 is disposed at a position close to the first opening OP1, it is easy to carry the tool (e.g., the first tool T1) taken out from the first support section 41 into the magazine 2 through the first opening OP1. Further, since the first tool T1 supported by the first support section 41 does not block the first opening OP1, it is easy to carry out another tool (e.g., the second tool T2) from the magazine 2 through the first opening OP1.

[0055] In the examples described in FIGS. 6, 12, and 13, the operator can perform the operation of taking out the tool from the tool temporary placement table 4 and the operation of carrying the taken-out tool into the magazine 2 without moving even one step. Further, the operator can perform the operation of carrying out the tool from the magazine 2 and the operation of temporarily placing the carried-out tool on the tool temporary placement table 4 without moving even one step.

[0056] In the examples described in FIGS. 6, 12, and 13, when the tool temporary placement table 4 is in the above-described use position Q2, the first support section 41 (more specifically, the first pocket 41p) is in front of the first wall 211 (e.g., the partition 211a described above) that defines one side portion of the first opening OP1 that defines the above-described first opening OP1, and is disposed below the first wall 211 (e.g., the partition 211a described above).

[0057] In the examples described in FIGS. 10, 11, and 15, when the tool temporary placement table 4 is in the above-described retracted position Q1, the first support section 41 is disposed vertically below the first wall 211 (e.g., the partition 211a described above). In this case, the first support section 41 can be stored by utilizing the space vertically below the first wall 211. In the examples described in FIGS. 10, 11, and 15, the first wall 211 is constituted by a hollow support column. Alternatively, the first wall 211 may be constituted by a plate-like body.

[0058] In the example described in FIG. 16, the above-described first orbit OB1 includes an arc orbit OB1-1. Further, in the magazine 2, a storage space SP1 for the tool temporary placement table 4 is formed. In the example described in FIG. 16, the storage space SP1 is arranged in the vicinity of the arc orbit OB1-1. The vicinity of the arc orbit OB1-1 is likely to be a dead space in terms of design. In the example described in FIG. 16, the vicinity of the arc orbit OB1-1 is utilized as the storage space SP1 for the tool temporary placement table 4.

[0059] (First holding part HA1) In the example described in FIG. 3, the magazine 2 includes a first holding part HA1 that moves along the first orbit OB1. More specifically, the magazine 2 includes a first group of holding parts HA that are movable along the first orbit OB1, and the first group of holding parts HA includes the first holding part HA1. A tool can be attached to each of the first group of holding parts HA. For example, a tool (e.g., the first tool T1) can be attached to the first holding part HA1 (see FIG. 17). Further, the first holding part HA1 can hold a tool (e.g., the first tool T1). Each of the first group of holding parts HA (e.g., the first holding part HA1) may include a gripper capable of gripping a tool or a pod capable of accommodating the shank of a tool.

[0060] (First moving device 51) The magazine 2 includes a first moving device 51 that moves the first group of holding parts HA (e.g., the first holding part HA1) along the first orbit OB1. In the example described in FIG. 18, the first moving device 51 includes a first chain 511 that supports the first group of holding parts HA (e.g., the first holding part HA1) and a first motor 515 that drives the first chain 511. The first moving device 51 may include a first sprocket 513 that engages with the first chain 511. In this case, the first motor 515 drives the first chain 511 via the first sprocket 513.

[0061] The first moving device 51 can move the first group of holding parts HA (for example, the first holding part HA1) in a first moving direction DM1 along the first track OB1, and can move the first group of holding parts HA (for example, the first holding part HA1) in a second moving direction DM2 along the first track OB1. The second moving direction DM2 is the direction opposite to the first moving direction DM1.

[0062] (The second holding part HB1) In the example shown in FIG. 3, the magazine 2 includes a second holding part HB1 that moves along the second track OB2. More specifically, the magazine 2 includes a second group of holding parts HB that are movable along the second track OB2, and the second group of holding parts HB includes the second holding part HB1. A tool can be attached to each of the second group of holding parts HB. For example, a tool (for example, the first tool T1 or another tool) can be attached to the second holding part HB1. Also, the second holding part HB1 can hold a tool (for example, the first tool T1 or another tool). The second track OB2 may be substantially parallel to the first track OB1. Each of the second group of holding parts HB (for example, the second holding part HB1) may include a gripper capable of gripping a tool, or may include a pod capable of accommodating the shank of a tool.

[0063] (The second moving device 53) The magazine 2 may include a second moving device 53 that moves the second group of holding parts HB (for example, the second holding part HB1) along the second track OB2. In the example shown in FIG. 19, the second moving device 53 includes a second chain 531 that supports the second group of holding parts HB (for example, the second holding part HB1), and a second motor 535 that drives the second chain 531. The second moving device 53 may include a second sprocket 533 that engages with the second chain 531. In this case, the second motor 535 drives the second chain 531 via the second sprocket 533.

[0064] The second moving device 53 can move the second group of holding parts HB (for example, the second holding part HB1) in a third moving direction DM3 along the second track OB2, and can move the second group of holding parts HB (for example, the second holding part HB1) in a fourth moving direction DM4 along the second track OB2. The fourth moving direction DM4 is the direction opposite to the third moving direction DM3.

[0065] (Frame structure 21) In the example shown in FIG. 20, the magazine 2 includes a frame structure 21 that defines the above-described first opening OP1.

[0066] The frame structure 21 includes a first wall 211 (for example, partition 211a) that defines one side portion of the first opening OP1, a second wall 213 that defines the other side portion of the first opening OP1, a first upper frame 214 that defines the upper end portion of the first opening OP1, and a first lower frame 215 that defines the lower end portion of the first opening OP1. In the example shown in FIG. 20, the tool temporary placement table 4 is disposed below the first lower frame 215.

[0067] In addition to the first opening OP1, the frame structure 21 may define a second opening OP2. In the example shown in FIG. 20, the first wall 211 (more specifically, the partition 211a) defines one side portion of the first opening OP1 and also defines one side portion of the second opening OP2.

[0068] In the example shown in FIG. 20, the frame structure 21 includes a third wall 216 that defines the other side portion of the second opening OP2, a second upper frame 217 that defines the upper end portion of the second opening OP2, and a second lower frame 218 that defines the lower end portion of the second opening OP2. In the example shown in FIG. 20, the tool temporary placement table 4 is disposed below the second lower frame 218.

[0069] (First support section 41) In the example shown in FIG. 20, the first support section 41 (more specifically, the first pocket 41p) can support the first tool T1 with the tip Te of the first tool T1 facing upward. In this case, the operator can easily check the shape of the tip Te of the first tool T1 supported by the first support section 41 and / or the state of the tip Te.

[0070] (ID reader 49a) As illustrated in FIG. 20, the tool storage device 1A may include an ID reader 49a capable of reading tool data including an ID for identifying the first tool T1. In the example described in FIG. 20, the tool temporary placement table 4 includes an ID reader 49a capable of reading an ID for identifying the first tool T1. More specifically, the tool temporary placement table 4 includes an ID reader 49a capable of reading an ID for identifying the first tool T1 disposed in the first support section 41.

[0071] When the tool temporary placement table 4 includes the ID reader 49a, the identification information of the first tool T1 supported by the first support section 41 can be checked and / or registered. The ID reader 49a may be communicable with the operation panel 6. For example, when the ID reader 49a reads information stored in the memory (e.g., IC chip, RFID tag, etc.) of the first tool T1, the tool data of the first tool T1 may be displayed on the display 60 of the operation panel 6.

[0072] (Second support section 43) As illustrated in FIGS. 21 to 23, the tool temporary placement table 4 may have a second support section 43 capable of supporting the second tool T2. In the example described in FIG. 21, the second support section 43 includes a second pocket 43p that supports the shank of the tool from below.

[0073] In the example shown in FIG. 23, when the tool temporary placement table 4 is in the use position Q2, the second support section 43 (more specifically, the second pocket 43p) is directly below the space in front of the first wall 211 (for example, the partition 211a). In other words, when the tool temporary placement table 4 is in the use position Q2, in a plan view, the direction from the first wall 211 (for example, the partition 211a) to the second support section 43 (more specifically, the second pocket 43p) coincides with the first direction DR1.

[0074] When the tool temporary placement table 4 includes the first support section 41 and the second support section 43, the first tool T1 to be carried into the magazine 2 can be temporarily placed in the first support section 41, and the second tool T2 carried out from the magazine 2 can be temporarily placed in the second support section 43.

[0075] In this specification, the direction from one side portion of the first opening OP1 to the other side portion of the first opening OP1 is defined as the second direction DR2. In the example shown in FIG. 21, the first support section 41 and the second support section 43 are arranged along the second direction DR2.

[0076] Alternatively, as illustrated in FIG. 24, the first support section 41 and the second support section 43 may be arranged along the depth direction of the magazine 2 (more specifically, a direction parallel to the first direction DR1).

[0077] As illustrated in FIGS. 21 and 24, the tool temporary placement table 4 may include a second ID reader 49b capable of reading an ID for identifying the second tool T2 arranged in the second support section 43.

[0078] In the examples shown in FIGS. 21 and 24, when the tool temporary placement table 4 is in the use position Q2, both the first support section 41 and the second support section 43 are outside the movement track OE1 of the first door 31 in a plan view. Additionally, when the tool temporary placement table 4 is in the use position Q2, both the first support section 41 and the second support section 43 may be outside the movement track OE2 of the second door 33 in a plan view.

[0079] In the example described in FIGS. 21 and 22 (or FIGS. 26 and 27), the position of the tool temporary placement table 4 can be changed between a retracted position Q1 where the first support section 41 and the second support section 43 are stored in the magazine 2 and a use position Q2 where the first support section 41 and the second support section 43 are exposed from the magazine 2.

[0080] In the example described in FIGS. 21 and 24, when the tool temporary placement table 4 is in the use position Q2, both the first support section 41 and the second support section 43 are located in front of the first wall 211 (for example, the partition 211a arranged between the first opening OP1 and the second opening OP2) in a plan view.

[0081] In this case, since the first support section 41 and the second support section 43 are arranged at a position close to the first opening OP1, the operator can efficiently place the tool on the tool temporary placement table 4 and carry the tool into the magazine 2 (or carry the tool out from the magazine 2 and place the tool on the tool temporary placement table 4). Further, the first tool T1 supported by the first support section 41 and / or the second tool T2 supported by the second support section 43 do not block the first opening OP1.

[0082] As illustrated in FIG. 22, when the tool temporary placement table 4 is in the retracted position Q1, the first support section 41 and / or the second support section 43 may be arranged vertically below the first wall 211 (for example, the partition 211a arranged between the first opening OP1 and the second opening OP2).

[0083] As illustrated in FIGS. 24 to 26, the tool temporary placement table 4 may be multi - stage type and pull - outable from the magazine 2. In the example described in FIG. 25, when the tool temporary placement table 4 is pulled out from the magazine 2 in the first stage, only one of the first support section 41 and the second support section 43 is exposed from the magazine 2. In the example described in FIG. 24, when the tool temporary placement table 4 is pulled out from the magazine 2 in the second stage, both the first support section 41 and the second support section 43 are exposed from the magazine 2.

[0084] (Handle 48) In the example shown in FIG. 3, the tool rest 4 is provided with a handle 48. In the example shown in FIG. 3, the handle 48 is a concave handle 48c. In other words, the tool rest 4 is provided with a concave handle 48c. In the example shown in FIG. 3, when the handle 48 (more specifically, the concave handle 48c) is pulled in the first direction DR1, the tool rest 4 is repositioned from the retracted position Q1 to the use position Q2.

[0085] (First example of the pulling-out method of the tool rest 4) In the examples shown in FIGS. 28 and 29, the tool rest 4 is supported by the magazine 2 so as to be tiltable about an axis substantially parallel to the horizontal plane (hereinafter referred to as the "third axis AX3"). In this case, the tool rest 4 can be pulled out from the retracted position Q1 to the use position Q2 in a tilting manner.

[0086] When the tilting method is adopted, the storage space SP1 of the tool rest 4 in the depth direction (more specifically, the storage space SP1 of the tool rest 4 in the direction parallel to the first direction DR1) can be made compact.

[0087] In the examples shown in FIGS. 28 and 29, the tilting angle about the third axis AX3 when the tool rest 4 tilts from the retracted position Q1 to the use position Q2 is less than 90 degrees. The tilting angle about the third axis AX3 when the tool rest 4 tilts from the retracted position Q1 to the use position Q2 may be 70 degrees or less, 60 degrees or less, or 50 degrees or less.

[0088] In the examples shown in FIGS. 28 and 29, the magazine 2 supports the lower end portion 4w of the tool rest 4 so as to be tiltable about the third axis AX3.

[0089] In the example shown in FIG. 28, when the tool rest 4 is in the use position Q2, the upper surface 40a of the tool rest 4 is substantially parallel to the horizontal plane. In the example shown in FIG. 29, when the tool rest 4 is in the retracted position Q1, the upper surface 40a of the tool rest 4 is inclined with respect to each of the horizontal plane and the vertical plane.

[0090] In the example shown in FIG. 29, when the tool temporary placement table 4 is in the retracted position Q1, the height of the upper end e1 of the first support section 41 is lower than the height of the lower end e2 of the first opening OP1. In the example shown in FIG. 29, when the tool temporary placement table 4 is in the retracted position Q1, the height of the upper end e1 of the first support section 41 is higher than the height of the lower end e3 of the first rail OB1. Alternatively, when the tool temporary placement table 4 is in the retracted position Q1, the height of the upper end e1 of the first support section 41 may be lower than the height of the lower end e3 of the first rail OB1.

[0091] In the example shown in FIG. 28, a storage space SP1 for the tool temporary placement table 4 is formed in the magazine 2. Also, in the example shown in FIG. 28, at least a part of the storage space SP1 is formed in a region that is higher than the lower end e3 of the first rail OB1 and lower than the height of the lower end e2 of the first opening OP1.

[0092] In the example shown in FIG. 29, when the tool temporary placement table 4 is in the retracted position Q1, the entire first support section 41 (more specifically, the entire first pocket 41p) is located in the first direction DR1 with respect to the end e4 on the first direction DR1 side of the first rail OB1. When the tool temporary placement table 4 is in the retracted position Q1, the entire tool temporary placement table 4 may be located in the first direction DR1 with respect to the end e4 on the first direction DR1 side of the first rail OB1.

[0093] The tool storage device 1A may include a magnet 93 that maintains the tool temporary placement table 4 in the retracted position Q1. The magnet 93 is disposed on one of the tool temporary placement table 4 and the magazine 2, and attracts the magnetic body of the other of the tool temporary placement table 4 and the magazine 2 by magnetic force.

[0094] As illustrated in FIGS. 28 and 29, the tool storage device 1A may include a damper 95 that suppresses an increase in the moving speed when the tool temporary placement table 4 moves from the retracted position Q1 to the use position Q2.

[0095] (Second example of the pulling-out method of the tool temporary placement table 4) In the examples described in FIGS. 24 to 27, the tool rest 4 is supported by the magazine 2 so as to be slidable in a direction substantially parallel to the horizontal plane. In this case, the tool rest 4 can be pulled out in a sliding manner from the retracted position Q1 to the use position Q2.

[0096] As illustrated in FIG. 27, the magazine 2 may include a guide rail 29 that slidably supports the tool rest 4.

[0097] In the examples described in FIGS. 26 and 27, the height of the upper end of the first support section 41 (more specifically, the height of the upper end of the first pocket 41p) is lower than the height of the lower end of the first opening OP1. The height of the upper end of the first support section 41 (more specifically, the height of the upper end of the first pocket 41p) may be higher than the height of the lower end e3 of the first track OB1, or may be lower than the height of the lower end e3 of the first track OB1.

[0098] (Third example of the pulling-out method of the tool rest 4) The tool rest 4 may be supported by the magazine 2 so as to be rotatable about a vertical axis. In other words, the tool rest 4 may be pullable out in a rotational manner about a vertical axis from the retracted position Q1 to the use position Q2.

[0099] (Locking member 97) As illustrated in FIGS. 3 and 30, the tool storage device 1A may include a locking member 97 that prohibits the tool temporary placement table 4 from changing its position from the retracted position Q1 to the use position Q2. The locking member 97 may be formed with a hexagonal hole portion 97h that is operated by a tool such as a hexagonal wrench. In the example shown in FIG. 30, when the hexagonal hole portion 97h is operated in the first rotation direction R1, the locking piece 97p of the locking member 97 moves from the unlocked position to the locked position. As a result, the locking piece 97p engages with the locked portion 27p of the magazine 2, and the tool temporary placement table 4 is prohibited from changing its position from the retracted position Q1 to the use position Q2. On the other hand, when the hexagonal hole portion 97h is operated in the second rotation direction R2, the locking piece 97p of the locking member 97 moves from the locked position to the unlocked position. As a result, the engagement between the locking piece 97p and the locked portion 27p of the magazine 2 is released, and the tool temporary placement table 4 is allowed to change its position from the retracted position Q1 to the use position Q2.

[0100] When the tool storage device 1A includes the locking member 97, the use of the tool temporary placement table 4 can be prohibited.

[0101] (Operation panel 6) The tool storage device 1A may include an operation panel 6 for operating the magazine 2.

[0102] In the example shown in FIG. 8, the tool storage device 1A (more specifically, the operation panel 6) includes a first switch 61 that operates the movement of the first group of holding portions HA (for example, the first holding portion HA1) in the direction along the first track OB1.

[0103] In the example described in FIG. 8, the operation panel 6 (for example, the first switch 61 described above) is disposed on the first wall 211 (for example, the partition 211a disposed between the first opening OP1 and the second opening OP2) that defines one side portion of the above-described first opening OP1. In the examples described in FIGS. 9 and 14, the first opening OP1 has one side portion relatively far from the first axis AX1 and the other side portion relatively close to the first axis AX1. In the examples described in FIGS. 9 and 14, the first wall 211 is a wall that defines one side portion relatively far from the first axis AX1 among the two side portions of the first opening OP1.

[0104] When the operation panel 6 is disposed on the first wall 211 (for example, the partition 211a), the operator can sequentially and smoothly (1) temporarily place a tool in the first support section 41 disposed in front of the first wall 211 in a plan view and (2) operate the operation panel 6.

[0105] As illustrated in FIGS. 9 and 14, when the tool temporary placement table 4 is in the use position Q2, the first support section 41 (more specifically, the first pocket 41p) may be in a position overlapping a straight line LN extending in the first direction DR1 from the operation panel 6 in a plan view. In other words, the first support section 41 (more specifically, the first pocket 41p) may be disposed directly below the space in front of the operation panel 6.

[0106] In the example described in FIG. 5, it is preferable that the operation panel 6 (for example, the first switch 61 described above) can be operated with the first opening OP1 closed by the first door 31. In the example described in FIG. 5, the operation panel 6 (for example, the first switch 61 described above) can be operated with the first opening OP1 closed by the first door 31 and the second opening OP2 closed by the second door 33.

[0107] As illustrated in FIG. 31, the operation panel 6 may include an emergency stop button 62. When the emergency stop button 62 is operated while the holding parts HA of the first group are moving along the first track OB1, the movement of the holding parts HA of the first group stops. When the emergency stop button 62 is operated while the holding parts HB of the second group are moving along the second track OB2, the movement of the holding parts HB of the second group stops.

[0108] As illustrated in FIG. 31, the operation panel 6 may include a manual operation selection switch 63. In the example shown in FIG. 31, manual operation of the magazine 2 becomes possible in response to the manual operation selection switch 63 being pressed. When the manual operation selection switch 63 is pressed once, manual operation of the magazine 2 becomes possible, and when the manual operation selection switch 63 is pressed twice, manual operation of the magazine 2 may become impossible. The manual operation selection switch 63 may light up when the manual operation of the magazine 2 becomes possible, and the manual operation selection switch 63 may go out when the manual operation of the magazine 2 becomes impossible.

[0109] When the magazine 2 includes the holding parts HA of the first group that move along the first track OB1 and the holding parts HB of the second group that move along the second track OB2 different from the first track OB1, the operation panel 6 may include a changeover switch 64 for switching the operation target between the holding parts HA of the first group and the holding parts HB of the second group. In the example shown in FIG. 31, an arrow AR1 indicating the direction of the holding parts HA of the first group may light up in response to the holding parts HA of the first group being selected as the operation target based on the operation of the changeover switch 64. An arrow AR2 indicating the direction of the holding parts HB of the second group may light up in response to the holding parts HB of the second group being selected as the operation target based on the operation of the changeover switch 64.

[0110] The operation panel 6 may be provided with an unlocking switch 65 for the first door 31. In the example shown in FIG. 31, when the unlocking switch 65 is pressed, the first door 31 is unlocked. When the first door 31 is in the unlocked state, the unlocking switch 65 may light up, and when the first door 31 is in the locked state, the unlocking switch 65 may turn off. When the unlocking switch 65 is pressed, both the first door 31 and the second door 33 may be unlocked.

[0111] The operation panel 6 may be provided with a tool number input key 66 (for example, a numeric keypad) and a tool number display unit 67. When a tool number is input using the tool number input key 66, the input tool number is displayed on the tool number display unit 67.

[0112] The operation panel 6 may be provided with a designated tool indexing key 68. In this specification, a holding unit that holds a tool corresponding to a tool number designated by an operator is defined as a designated holding unit. In the example shown in FIG. 31, the operator can specify a tool number using the tool number input key 66. In the example shown in FIG. 31, when the designated tool indexing key 68 is pressed while a tool number is specified, the designated holding unit moves to a predetermined indexing position D. For example, when the designated holding unit is included in the first group of holding units HA, the first moving device 51 moves the first group of holding units HA along the first track OB1 so that the designated holding unit moves to the first indexing position D1 (see FIG. 8). On the other hand, when the designated holding unit is included in the second group of holding units HB, the second moving device 53 moves the second group of holding units HB along the second track OB2 so that the designated holding unit moves to the second indexing position D2 (see FIG. 8).

[0113] The tool number display unit 67 may be configured to display the number of the tool held in the holding unit located at the predetermined indexing position D. In other words, the tool number display unit 67 may be configured to selectively display the tool number input using the tool number input key 66 and the tool number held in the holding unit located at the predetermined indexing position D. In the example described in FIG. 31, when the tool number input using the tool number input key 66 is displayed on the tool number display unit 67, the first display lamp 69a lights up. On the other hand, when the tool number held in the holding unit located at the predetermined indexing position D is displayed on the tool number display unit 67, the second display lamp 69b lights up. Alternatively, as illustrated in FIG. 33, a display unit 77 that displays the tool number held in the holding unit located at the predetermined indexing position D may be provided separately from the tool number display unit 67 that displays the tool number specified using the tool number input key 66.

[0114] As illustrated in FIG. 31, the operation panel 6 may include a forward rotation key 71. For example, in response to the forward rotation key 71 being pressed, the first moving device 51 moves the first group of holding units HA in the first moving direction DM1 (see FIG. 18) along the first track OB1. More specifically, in a state where the first group of holding units HA is selected as the operation target by the operation of the changeover switch 64, in response to the forward rotation key 71 being pressed, the first moving device 51 moves the first group of holding units HA in the first moving direction DM1 (see FIG. 18) along the first track OB1. In a state where the second group of holding units HB is selected as the operation target by the operation of the changeover switch 64, in response to the forward rotation key 71 being pressed, the second moving device 53 may move the second group of holding units HB in the third moving direction DM3 (see FIG. 19) along the second track OB2.

[0115] The operation panel 6 may be provided with a reverse key 72. For example, in response to the reverse key 72 being pressed, the first moving device 51 moves the first group of holding parts HA in a second moving direction DM2 (see FIG. 18) along the first track OB1. More specifically, in a state where the first group of holding parts HA is selected as an operation target by operating the changeover switch 64, in response to the reverse key 72 being pressed, the first moving device 51 moves the first group of holding parts HA in a second moving direction DM2 (see FIG. 18) along the first track OB1. In a state where the second group of holding parts HB is selected as an operation target by operating the changeover switch 64, in response to the reverse key 72 being pressed, the second moving device 53 may move the second group of holding parts HB in a fourth moving direction DM4 (see FIG. 19) along the second track OB2.

[0116] When the operation panel 6 is provided with a forward key 71 and / or a reverse key 72, the operator can continuously check a plurality of tools held by the first group of holding parts HA (or a plurality of tools held by the second group of holding parts HB) through the first transparent window 317 of the first door 31 (or through the second transparent window 337 of the second door 33).

[0117] When the first door 31 is in the open position, among the operations of the plurality of switches included in the operation panel 6, the operations involving the movement of the first group of holding parts HA are invalidated. When the second door 33 is in the open position, among the operations of the plurality of switches included in the operation panel 6, the operations involving the movement of the second group of holding parts HB are invalidated.

[0118] As illustrated in FIG. 32, the operation panel 6 may be provided with a display 60 for displaying tool data. The display 60 may be a touch panel display 60t.

[0119] In the example shown in FIG. 32, a list LT of a plurality of tools stored in the magazine 2 is displayed on the display 60 of the operation panel 6. In the example shown in FIG. 32, the list LT includes the tool number 81, the tool name 82, and the tool size 83 (for example, the tool diameter) of each of the plurality of tools.

[0120] In the example shown in FIG. 32, the operator can specify the tool number by selecting a desired tool from the list LT. In the example shown in FIG. 32, when a tool with the tool number "2" is selected from the list LT, the tool with the tool number "2" is specified. The tool number of the specified tool may be displayed on the tool number display section 67.

[0121] Alternatively, as illustrated in FIG. 33, the operator may specify the tool number by directly inputting the tool number of the desired tool. In the examples shown in FIGS. 32 and 33, in a state where the tool number is specified, in response to the specified tool extraction key 68 being pressed, the specified holding section moves to a predetermined extraction position D (see FIG. 8).

[0122] In the examples shown in FIGS. 34 and 35, the tool data DA read by the ID reader 49a of the tool temporary placement table 4 can be displayed on the display 60. For example, in response to the ID reader 49a of the tool temporary placement table 4 reading the information stored in the memory of the first tool T1 supported in the first support section 41, the tool data DA1 of the first tool T1 is displayed on the display 60.

[0123] In the example shown in FIG. 34, in response to the pressing of the first button 75 on the operation panel 6 (for example, the first button 75 on the display 60t with a touch panel), the tool data DA read by the ID reader 49a is transmitted as data indicating the tool to be loaded into the magazine 2 to the control device 110 of the machine tool (see FIG. 37). More specifically, in a state where the tool attachment tab 74a is selected, in response to the pressing of the first button 75 on the operation panel 6, the tool data DA read by the ID reader 49a is transmitted as data indicating the tool to be loaded into the magazine 2 to the control device 110 of the machine tool.

[0124] In the example shown in FIG. 35, in response to the pressing of the second button 76 on the operation panel 6 (for example, the second button 76 on the display 60t with a touch panel), the tool data DB read by the ID reader 49a is transmitted as data indicating the tool unloaded from the magazine 2 to the control device 110 of the machine tool (see FIG. 37). More specifically, in a state where the tool removal tab 74b is selected, in response to the pressing of the second button 76 on the operation panel 6, the tool data DB read by the ID reader 49a is transmitted as data indicating the tool unloaded from the magazine 2 to the control device 110 of the machine tool.

[0125] When the tool temporary placement table 4 is in the use position Q2, the distance L1 (see FIG. 36) in the direction along the vertical direction between the upper end 410u of the first support section 41 (more specifically, the first pocket 41p) and the lower end 6w of the operation panel 6 is, for example, 20 cm or more, 30 cm or more, or 35 cm or more. When the distance L1 is sufficiently large, when a long tool is supported by the first support section 41, the operation of the operation panel 6 is not obstructed by the tool.

[0126] (Cable CB) The tool storage device 1A may include a cable CB that communicably connects the operation panel 6 and other devices (for example, the first motor 515, the second motor 535, the control device 110, etc.). In the example shown in FIG. 16, a part of the cable CB is disposed inside the above-described first wall 211 (for example, the partition 211a disposed between the first opening OP1 and the second opening OP2).

[0127] (Second Embodiment) With reference to FIGS. 1 to 39, the machine tool 100 in the second embodiment will be described. FIG. 37 is a schematic perspective view schematically showing the machine tool 100 in the second embodiment. FIG. 38 is a view schematically showing a part of the machine tool 100 in the second embodiment. FIG. 39 is a view schematically showing a state in which the control device 110 can control a plurality of controlled devices.

[0128] In the second embodiment, the description will be centered on the differences from the first embodiment. On the other hand, in the second embodiment, repeated descriptions of matters already described in the first embodiment will be omitted. Therefore, in the second embodiment, even if not explicitly described, it goes without saying that the matters already described in the first embodiment can be applied to the second embodiment. Conversely, all matters described in the second embodiment are applicable to the first embodiment.

[0129] As illustrated in FIG. 38, the machine tool 100 in the second embodiment includes a work support device 101, a machining head 103, a moving device 105, and a tool storage device 1. The machine tool 100 may include a tool changer 107.

[0130] The work support device 101 supports the work W. The machining head 103 can hold a tool T for machining the work W. The machining head 103 can hold the first tool T1 and can hold a second tool T2 different from the first tool T1.

[0131] The moving device 105 relatively moves the machining head 103 with respect to the work support device 101.

[0132] The tool storage device 1 may be the tool storage device 1A in the first embodiment, or other tool storage devices.

[0133] As illustrated in FIG. 1, the tool storage device 1 includes: (1) a magazine 2 that stores a plurality of tools held by a plurality of holding parts HA movable along a first track OB1; (2) a first opening OP1 formed in the magazine 2 through which a first tool T1 passes when the first tool T1 is carried into the magazine 2; (3) a first door 31 capable of opening and closing the first opening OP1; and (4) a tool temporary placement table 4 having a first support section 41 capable of supporting the first tool T1. Further, the tool temporary placement table 4 is disposed below the first opening OP1 and supported by the magazine 2.

[0134] The machine tool 100 in the second embodiment has the same effects as the tool storage device 1A in the first embodiment.

[0135] (Optional additional configuration) Subsequently, with reference to FIGS. 1 to 39, an optional additional configuration that can be adopted in the machine tool 100 in the second embodiment will be described.

[0136] (Machine tool 100) In the example shown in FIG. 38, the machine tool 100 in the second embodiment is a multi - function machine capable of performing a plurality of types of machining including turning and milling. The machine tool 100 in the second embodiment may be a machining center (for example, a vertical machining center or a horizontal machining center), or a lathe.

[0137] In the example described in FIG. 37, the machine tool 100 includes an opening 121 through which a workpiece can be carried into the machining area, and a door 123 that can open and close the opening 121. In this specification, the side where the opening 121 is located is defined as the front side FS (i.e., the front side of the machine tool), and the side opposite to the side where the opening 121 is located is defined as the rear side (i.e., the rear side of the machine tool). In the example described in FIG. 37, the first opening OP1 of the tool storage device 1 is provided on the front side FS. In other words, in the example described in FIG. 37, the first opening OP1 of the tool storage device 1 is arranged on the same side as the opening 121 through which the workpiece can be carried into the machining area. More specifically, the first opening OP1 of the tool storage device 1 is arranged on the first direction DR1 side of the machine tool 100, and the opening 121 through which the workpiece can be carried into the machining area is arranged on the first direction DR1 side of the machine tool 100. Also, in the example described in FIG. 37, the position of the tool temporary placement table 4 can be changed between a retracted position Q1 where the first support section 41 is stored in the magazine 2 and a use position Q2 where the first support section 41 is exposed from the magazine 2 (see FIG. 5).

[0138] When both the opening 121 and the first opening OP1 are provided on the front side FS, the moving distance of the operator for carrying in and out tools and workpieces can be short. Also, since the tool temporary placement table 4 can be stored in the retracted position Q1, the tool temporary placement table 4 does not interfere with the movement of the operator.

[0139] Alternatively, the first opening OP1 of the tool storage device 1 may be provided on the rear side. In other words, the first opening OP1 of the tool storage device 1 may be arranged on the side opposite to the opening 121 through which the workpiece can be carried into the machining area.

[0140] (Work support device 101) In the example shown in FIG. 38, the work support device 101 includes a chuck 101a that holds the work W, and a chuck rotation device 101b that rotates the chuck 101a around the rotation axis. Alternatively, or additionally, the work support device 101 may include a table that supports the work. Further, the work support device 101 may include a table rotation device that rotates the table around the rotation axis.

[0141] (Processing head 103) In the example shown in FIG. 38, the processing head 103 includes a rotation drive device 103b that rotates the tool T around an axis parallel to the longitudinal direction of the tool (hereinafter referred to as the "fourth axis AX4"). In the example shown in FIG. 38, when the tool T rotating around the fourth axis AX4 contacts the work, the work is processed by the tool T. Alternatively, a turning tool may be held by the processing head 103. In this case, with the work W and the chuck 101a holding the work W rotating around the rotation axis, the turning tool contacts the work W. Thus, the work W is processed by the turning tool.

[0142] (Moving device 105) In the example shown in FIG. 38, the moving device 105 includes a processing head moving device 106 that moves the processing head 103. The processing head moving device 106 may include a first linear motion device 106a that moves the processing head 103 along the vertical direction. Alternatively, or additionally, the processing head moving device 106 may include a second linear motion device 106b that moves the processing head 103 along the horizontal direction. Alternatively, or additionally, the processing head moving device 106 may include a tilting device 106c that tilts the processing head 103.

[0143] Alternatively, or additionally, the moving device 105 may include a work moving device that linearly moves the chuck 101a that holds the work W (or the table that supports the work W).

[0144] (Tool changer 107) The machine tool 100 may be provided with a tool changer 107 that can replace the tool T held by the machining head 103 with another tool taken out from the tool storage device 1. The tool changer 107 may include a tool changing arm 108 having a first gripping portion 108a capable of gripping a tool and a second gripping portion 108b capable of gripping another tool. Further, the tool changer 107 may include an arm rotating device 109a for rotating the tool changing arm 108 and an arm moving device 109b for linearly moving the tool changing arm 108.

[0145] (Control device 110) As illustrated in FIG. 37, the machine tool 100 may be provided with a control device 110 that controls the tool storage device 1 and the moving device 105. The control device 110 may control the machining head 103 (more specifically, the rotational drive device 103b). Further, the control device 110 may control the work support device 101 (more specifically, the chuck rotating device 101b). The control device 110 may control the tool changer 107 (more specifically, the arm rotating device 109a and the arm moving device 109b).

[0146] As illustrated in FIG. 39, the control device 110 includes a hardware processor 111 (hereinafter simply referred to as "processor 111"), a memory 112, a communication circuit 114, and an input device 116t (for example, a display 116 with a touch panel). The processor 111, the memory 112, the communication circuit 114, and the input device 116t are connected to each other via a bus 118. Data necessary for machining the work W (for example, work data including the shape data of the work W and the machining position data of the work W) may be input to the control device 110 via the input device 116t, or may be input to the control device 110 from another computer via the communication circuit 114. Note that the input device 116t is not limited to the display 116 with a touch panel. For example, the control device 110 may include an input device such as a button, a switch, a lever, a pointing device, a keyboard, etc., and a display for displaying the data input to the input device or other information.

[0147] By executing the processing program PM stored in the memory 112, the control device 110 generates a plurality of control commands. Further, the communication circuit 114 transmits the plurality of control commands generated by the control device 110 to the controlled devices such as the moving device 105. In this way, the control device 110 can control the controlled devices such as the moving device 105.

[0148] The control device 110 may control the tool storage device 1, the moving device 105, and the tool changer 107. For example, by executing the processing program PM stored in the memory 112, the control device 110 transmits a tool rotation command S1 to the tool storage device 1 (more specifically, the first moving device 51 and / or the second moving device 53) via an amplifier (not shown in FIG. 39), transmits a movement command S2 to the moving device 105 (more specifically, the machining head moving device 106), and transmits a tool change command S3 to the tool changer 107.

[0149] The tool storage device 1 (more specifically, the first moving device 51 and / or the second moving device 53) that receives the tool rotation command S1 moves the first designated tool specified by the processing program PM toward the tool changer 107. The moving device 105 (more specifically, the machining head moving device 106) that receives the movement command S2 moves the machining head 103 toward the tool changer 107. The tool changer 107 that receives the tool change command S3 exchanges the tool held by the machining head 103 with the first designated tool taken out from the tool storage device 1.

[0150] In the example described in FIG. 39, the memory 112 includes a stored tool database 112a. In the stored tool database 112a, the tool data DT of each of the plurality of tools stored in the magazine 2 is stored.

[0151] In the example described in FIG. 39, the control device 110 can communicate with the operation panel 6. For example, the control device 110 receives the tool data DA read by the ID reader 49a from the operation panel 6. The control device 110 registers the tool data DA received from the operation panel 6 in the stored tool database 112a, or stores it in the memory 112 as data to be registered in the stored tool database 112a. In the latter case, the tool data DA is registered in the stored tool database 112a after an approval operation by the operator at a later time.

[0152] For example, the control device 110 transmits a list LT of a plurality of tools stored in the magazine 2 in response to a request from the operation panel 6. The processor 6p of the operation panel 6 causes the received list LT to be displayed on the display 60.

[0153] For example, the operation panel 6 transmits the tool data DA read by the ID reader 49a to the control device 110 as data indicating the tool to be carried into the magazine 2. In this case, the control device 110 registers the tool data DA received from the operation panel 6 in the stored tool database 112a. Alternatively, the control device 110 may store the tool data DA received from the operation panel 6 in the memory 112 as data to be registered in the stored tool database 112a. In this case, the tool data DA is registered in the stored tool database 112a after an approval operation by the operator at a later time.

[0154] For example, the operation panel 6 transmits the tool data DB read by the ID reader 49a to the control device 110 as data indicating the tool carried out of the magazine 2. In this case, the control device 110 deletes the tool data DB received from the operation panel 6 from the stored tool database 112a. Alternatively, the control device 110 may store the tool data DB received from the operation panel 6 in the memory 112 as data to be deleted from the stored tool database 112a. In this case, the tool data DB is deleted from the stored tool database 112a after an approval operation by the operator at a later time.

[0155] The present invention is not limited to the above-described embodiments or each modification example, and it is obvious that each embodiment or each modification example can be appropriately modified or changed within the scope of the technical idea of the present invention. Further, various techniques used in each embodiment or each modification example are applicable to other embodiments or other modification examples as long as no technical contradiction occurs. Furthermore, any additional configuration in each embodiment or each modification example can be appropriately omitted.
