Abstract

PROBLEM TO BE SOLVED: To provide a tool accommodating device which can make mounting and removal of a tool pot easily to a component situated on the side with a transporting mechanism. SOLUTION: A bracket 18 is fixed to a chain 16 as a transporting mechanism, and a tool pot 10 is held by this bracket 18. The tool pot 10 and bracket 18 are in condition that they can individually be mounted and removed, and there is no risk that the tool pot 10 falls out from the bracket 18 in transit because other structure such as a tilting mechanism 20 restricts the allowable range for the motion of the tool pot 10. If the tilting mechanism 20 is removed, the works to mount and remove the tool pot 10 to/from the bracket 18 can be executed very easily.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tool storage device provided in a machine tool having an automatic tool changing function.

[0002]

2. Description of the Related Art Conventionally, a tool storage device provided in a machining center has a structure in which a tool pot can be transferred along a predetermined path. Conventionally, in this type of tool storage device, in order to prevent the tool pot from dropping off from a part on the transfer mechanism side when the tool pot is transferred,
For example, a bearing hole is formed in each of the tool pot and the part on the transfer mechanism side, and one rotating shaft is inserted so as to penetrate both bearing holes, and the rotating shaft is not easily dropped off. The tool pot and the part on the transfer mechanism side are relatively firmly connected by the configured mounting structure.

[0003]

However, in the case of the above-described mounting structure, the operation of connecting the tool pot and the parts on the transfer mechanism side is relatively troublesome and troublesome, so that a large number of tools are required. There was a problem that it took considerable time to attach the pot. Further, particularly, when the component on the transfer mechanism side is assembled into the fixed structure of the tool storage device, and then the tool pot is attached to the component on the transfer mechanism side, it is troublesome in a narrow space in the fixed structure. There is a drawback that you will have to work, on the other hand, after attaching the tool pot to the parts on the transfer mechanism side,
Attempting to incorporate the components of the transfer mechanism into the fixed structure of the tool storage device has the disadvantage that the components of the transfer mechanism that have become considerably heavy due to the large number of tool pots must be assembled. There is a problem that the work of attaching and detaching the tool pot for work and maintenance is extremely troublesome.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a tool capable of attaching and detaching a tool pot to and from a part on a transfer mechanism side more easily than in the past. An object of the present invention is to provide a storage device.

[0005]

Means for Solving the Problems and Effects of the Invention In order to achieve the above object, the present invention provides a tool pot in which a tool is loaded and unloaded by a tool changing device, and a tool pot according to the present invention. In a tool storage device having a transfer means for transferring the pot along a predetermined path, the transfer means,
While the tool pot is held detachably, the tool pot is transported, and the tool pot is brought into contact with the tool pot to limit the allowable operation range of the tool pot. It is provided with a falling-off preventing means for preventing falling-off from the transfer means, and at least a part of the falling-off preventing means is structured so as to be able to be arbitrarily moved from a regular mounting position. The tool pot is configured to be attachable to and detachable from the transfer means.

In this tool storage device, the tool pot is detachably held by the transfer means.
The detachable means here means that the tool pot can be freely removed from the transfer means by simply displacing the relative positional relationship between the transfer means and the tool pot without removing parts such as screws and pins. It means that it has become.

[0007] At least a part of the means for preventing falling off includes:
Although it has a structure that can be moved arbitrarily from the regular mounting position, this is usually a fixed mounting position if it can be moved from the regular mounting position in some way. I do not care. For example, even if the falling-off prevention means is screwed to the proper mounting position, there is no problem as long as the screw can be loosened or removed and moved. In addition, the drop-out prevention means can be completely detached as long as the tool pot can be moved to a position where the tool pot can be attached to and detached from the transfer means. Or, it may be one that can be rotated via a hinge.

[0008] According to this tool storage device, the transfer means includes:
Although it only holds the tool pot freely detachable,
Since the falling-off preventing means abuts on the tool pot to limit the allowable operation range of the tool pot, the tool pot does not fall off from the transfer means when the tool pot is transferred by the transfer means. On the other hand, the limitation on the allowable operation range of the tool pot is released only by moving at least a part of the drop prevention means, so that the tool pot can be easily attached to and detached from the transfer means.

Therefore, although the trouble of moving at least a part of the falling-off preventing means is increased, it is not necessary to load and remove a large number of tool pots, so that all of the large number of tool pots do not fall to the transfer means. This has the effect of greatly reducing the time required for attaching and detaching the tool pot, as compared with the case of attaching and detaching the tool pot.

Further, even when the space near the transfer means is narrow, troublesome manual work such as screwing work is performed in the narrow space, or the tool pot is attached to the part on the transfer means side in advance, Since it is not necessary to integrate both into the tool storage device, there is an effect that the work of attaching and detaching the tool pot for assembling work and maintenance can be performed very easily.

According to a second aspect of the present invention, there is provided a tool storage device, wherein a rotating shaft is provided on one of the tool pot and the transfer means, and a bearing is provided on the other, and the rotating shaft is supported by the bearing. By doing so, the tool pot is held by the transfer means in a rotatable state, and the bearing rotatably supports the rotating shaft by a notch that allows the rotating shaft to be taken in and out. Thereby, the tool pot is configured to be held by the moving means in a detachable state, and further, at a position other than the indexing position set on the predetermined path, the rotation of the tool pot is regulated. A rotation restricting means for maintaining the tool pot in a retracted state, and being able to execute attachment / detachment of the tool pot in the retracted state or the tool changing device at an indexing position set on the predetermined path. And a tilt means for rotating the one of conversion state, the rotation regulating means, the tilting means, and / or other member, characterized by being configured the drop-off preventing means.

According to this tool storage device, the transfer means holds the tool pot rotatably by pivotally supporting the rotation shaft by the bearing. At positions other than the indexing position set on the predetermined path, the rotation restricting means restricts the rotation of the tool pot and maintains the tool pot in the retracted state. , The tilting means rotates the tool pot to either the retracted state or the replaceable state,
When the tool pot is rotated to the exchangeable state, the loading and unloading of the tool by the tool exchange device can be executed.

[0013] Further, since a notch portion is provided as a bearing so that the rotating shaft can be freely inserted and removed, the tool pot is merely held detachably by the transfer means. Since the falling-off prevention means abuts on the tool pot to limit the allowable operation range of the tool pot, the tool pot does not fall off from the transfer means when the tool pot is transferred by the transfer means. By only moving at least a part of the tool pot, the limitation on the allowable operation range of the tool pot is released, so that the tool pot can be easily attached to and detached from the transfer means.

Therefore, the present invention has the same effect as that of the first aspect, and furthermore, by rotating the tool pot to the retracted state, the tool pot can be transferred in a state suitable for transfer. This has the effect. In the case where the rotation restricting means and the tilting means constitute the falling-off preventing means, the number of parts can be reduced as compared with the case where only the exclusive falling-off preventing means is provided separately from the rotation restricting means and the tilting means. There is also an effect that can be done.

The tool storage device according to a third aspect of the present invention is arranged such that a chain circulating in a predetermined plane is provided as the transfer means, the bearing is attached to an outer peripheral side of the chain, and the tool pot side is attached to the chain. The rotating shaft and the bearing are arranged on the side of the transfer means, respectively, and the shape of the notch portion of the bearing is set so that the axial direction of the rotating shaft and the moving direction of the rotating shaft by the chain are matched. The rotary shaft can be supported, and the tool pot can be moved in a direction intersecting the running surface of the chain so that the rotary shaft can be freely inserted and removed without removing the rotary shaft from the tool pot. It is characterized by having a shape.

According to this tool storage device, a chain is provided as the transfer means, and the rotation on the tool pot side is supported by the bearing on the outer peripheral side of the chain, so that the transfer means can rotate the tool pot. keeping. In particular, the shape of the notch portion of the bearing is such that the axial direction of the rotating shaft and the moving direction of the rotating shaft by the chain can be matched, and the rotating shaft can be supported, and the tool pot can be supported on the running surface of the chain. By moving in a direction intersecting with each other, the rotating shaft can be freely inserted and removed without removing the rotating shaft from the tool pot.

[0017] Therefore, in addition to the same effects as those of the second aspect, the force for moving the chain and the force for rotating the tool pot do not act in the direction of dropping the rotating shaft from the bearing. There is an effect that the center of rotation of is easily stabilized. Next, in the tool storage device according to the fourth aspect, the tool pot is in the storage state by providing the tool pot and the transfer unit with an engagement portion that engages when the tool pot is in the storage state. At the indexing position, the tool pot is rotated while the tool pot is held at the indexing position, whereby the tool pot is replaceable. In the state, it is prevented from dropping off from the transfer means, and a part of the tilting means is configured to be able to be arbitrarily moved from a regular mounting position. The bearing is moved to a position so that the tool pot can be attached to and detached from the transfer means.

According to this tool storage device, when the tool pot is in the retracted state, the engagement portions provided on the tool pot and the transfer means are engaged to prevent the tool pot from falling off from the transfer means. On the other hand, when the tool pot is in a replaceable state, the engagement of the engaging portion is released, but the tilting means rotates the tool pot while holding the tool pot. Therefore, these engaging portions and tilting means function as drop-off preventing means, restricting the allowable operation range of the tool pot, and preventing the tool pot from dropping out of the transfer means. Further, in particular, since a part of the tilting means can be arbitrarily moved from the regular mounting position, the engagement portion and the engagement portion can be released simply by rotating the tool pot to the exchangeable state at the indexing position to release the engagement. The restriction on the allowable operation range by the tilting means can be released.

Therefore, in addition to the same effect as that of the third aspect, the engaging portion may be fixed at a regular mounting position, and the structure of the engaging portion which must be provided in each tool pot. Can be made as simple as possible.

[0020]

Next, an embodiment of the present invention will be described with reference to an example. As shown in FIGS. 1 and 2, a tool storage device 1 exemplified as an embodiment includes a plurality of tool pots 10, and the tool pots 10 are arranged inside a magazine base 11 fixed to a machine tool body. It is mounted on the installed transfer mechanism 12.

The transfer mechanism 12 includes a pair of sprockets 13 and 1 rotatably disposed inside the magazine base 11.
4, an endless chain 16 bridged between the sprockets 13 and 14, a bracket 18 fixed to the outer periphery of the chain 16, and the like. 18 and one sprocket 13 is connected to a motor (not shown).
When it is rotationally driven, it is transported along a path that circulates with the chain 16.

Although the plurality of tool pots 10 are all rotatably mounted on the bracket 18, the tool pot 10 has a large portion on the outer periphery of the magazine base 11 in most of the transfer path of the tool pot 10. The inner wall surface 11a is in contact with the tool pot 10. Therefore, the inner wall surface 11a is in a state of restricting the rotation of the tool pot 10, and the tool pot 10 is maintained in a state where the tool T is directed to the front (hereinafter, referred to as a stored state).

On the other hand, a slot 11b is formed at the lower end of the magazine base 11, and only at the position where the slot 11b is formed (hereinafter referred to as indexing position), the tool pot 10b is formed.
Is rotatable from the stored state to a state in which the tool T is directed downward (a state shown by a two-dot chain line in the figure; hereinafter, referred to as a replaceable state). As shown in FIGS. 3 and 4, a tilting mechanism 20 for rotating the tool pot 10 into the retracted state or the replaceable state is provided at the index position.

The tilting mechanism 20 includes a positioning member 21 fixed in the magazine base 11, a rotation member 22 rotatably mounted on the outer periphery of the positioning member 21, and a rotation member 2.
The positioning member 21 is used to maintain the center of rotation of the tool pot 10 at a fixed position, and the link rod 24 is moved up and down to rotate the rotating member 22. By this, tool pot 1
0 rotates to a stored state (see FIG. 3) or an exchangeable state (see FIG. 4).

An actuator case 26 is provided above the magazine base 11. Inside the actuator case 26, a motor (not shown) for driving the sprocket 13 and the link rod 24 are moved up and down. An air cylinder (to be described in detail later) is stored in the housing.

Next, the structure of the tool pot 10 and the mounting structure of the tool pot 10 to the bracket 18 will be described in more detail. The tool pot 10 is
As shown in FIGS. 5A to 5C, a main body 31 having a tool mounting hole 30 formed on the front side, and a pair of pot arms 32 projecting rearward from the rear side of the main body 31 in parallel.
And an end of the pot arm 32 with its axis centered in the left-right direction.
, A positioning roller 36 rotatably mounted on the outer periphery of the rotating shaft 34 inside the pot arm 32, and an axial line provided on the bottom side of the main body 31 and extending in the front-rear direction Transfer roller 38 rotatable about
And provided inside the vicinity of the base of the pot arm 32,
Auxiliary roller 4 rotatable about an axis extending in the front-rear direction
And a locking pin 42 protruding from both sides of the main body 31 near the front side.

Of these, the rotating shaft 34 is mounted on the bracket 1
8 is a part which is rotatably held. The positioning roller 36 fits inside the positioning member 21 when the tool pot 10 is transferred to the indexing position. It has a tapered shape. When the tool pot 10 is transferred, the transfer roller 38 rotates when it comes into contact with the inner wall surface 11a of the magazine base 11 (see FIG. 1), thereby preventing the tool pot 10 and the magazine base 11 from rubbing at the contact point. doing. The auxiliary roller 40 does not contact any part when the chain 16 is sufficiently tensed. However, when the tension of the chain 16 is loosened for some reason, the auxiliary roller 40 comes into contact with a member or the like on the magazine base 11 side. Thus, the positioning roller 36 and the like are prevented from being rubbed against unexpected places.

On the other hand, the bracket 18 is shown in FIG.
As shown in FIG. 3C, both ends of the rectangular flat plate-shaped chain mounting portion 50 fixed to the chain 16 are bent downward, and a pair of bracket arms 52 are rearwardly parallel from the bent portion. It has a protruding shape.
A first cutout 54 is formed at the tip of the bracket arm 52, and a second cutout 54 is formed at the front lower end of the bracket 18.
A notch 56 is formed. This bracket 18
Is fixed to the chain 16 as shown in FIGS. 3 and 4, and the bracket arm 52 is held in a state of extending substantially horizontally rearward.

The tool pot 10 and the bracket 18 configured as described above are connected to the first notch 5 of the bracket 18.
By fitting the turning shaft 34 of the tool pot 10 into the tool pot 4, the tool pot 10 is rotatably connected. The rotating shaft 34 is simply fitted into the first cutout 54, but when the tool pot 10 is in the retracted state, as shown in FIG.
The locking pin 42 of the tool pot 10 just fits into the second cutout 56 of the bracket 18 and the tool pot 1
0 cannot move backward, and the rotating shaft 34 cannot be removed from the first cutout 54. Therefore, not only the indexing position shown in FIG.
Is moved in a range other than the indexing position, there is no possibility that the tool pot 10 will fall off the bracket 18 as long as the tool pot 10 is maintained in the retracted state. Further, when the tool pot 10 rotates to the exchangeable state at the indexing position, as shown in FIG.
The engagement between the locking pin 42 and the second notch 56 is released, but at the indexing position, the positioning roller 36 of the tool pot 10 fits inside the positioning member 21, and the tool pot 10 is also moved backward. And the rotating shaft 34 cannot be taken out from the first cutout portion 54. Therefore, even when the tool pot 10 is at the indexing position, there is no possibility that the tool pot 10 will fall off the bracket 18. That is, as long as the tool pot 10 is transferred or tilted within the normal movable range by the transfer mechanism 12 and the tilting mechanism 20, there is no possibility that the tool pot 10 will fall off the bracket 18.

On the other hand, when the tilting mechanism 20 is removed from the tool storage device 1, the tool pot 10 and the bracket 18 configured as described above become disengaged at the indexing position.
Since there is no member for preventing the attachment / detachment of the tool pot 10, the attachment / detachment of the tool pot 10 can be freely performed.

Therefore, when mounting the tool pot 10, the chain 1 to which only the bracket 18 is fixed is attached.
6 after being bridged between the sprockets 13 and 14,
The tool pot 10 is inserted from the split outlet 11b, fitted into the bracket 18, the tool pot 10 is rotated to the retracted state, the chain 16 is transported by a predetermined amount, and the mounting of the tool pot 10 is repeated. Mechanism 20
You only have to attach.

Therefore, the tool pot 1 can be very easily
0 can be attached, and the installation work is troublesome like a conventional product, for example, a work in which a tool pot is attached in advance and a very heavy chain is put on a sprocket, or a chain is put on a sprocket. There is no need to perform any operation such as later inserting a hand into a narrow space and screwing or pinning the tool pot to the chain.

Next, the tilting mechanism 20 of the tool storage device 1
Will be described in detail. The positioning member 21 is shown in FIG.
(A), as shown in FIG.
Mounting portion 60 which is screwed to
And a roller holding portion 62 which is provided integrally below and can hold the positioning roller 36 on the cylindrical inner wall surface 62a. The roller holding unit 62 includes the pot arm 3.
A horizontal passage 62b for passing the second and bracket arms 52 when the tool pot 10 is transferred, and a vertical passage 62c for passing the pot arm 32 when the tool pot 10 is tilted are cut off.

As shown in FIGS. 3 and 4, the rotating member 22 includes a rotating plate 64 and an upper plate 6.
6, a lower plate 68, and a link shaft 69. Of these, the rotating plate 64 is provided on both sides of the mounting member 60 of the positioning member 21 on one side.
The rollers are attached one by one, and all are rotatably fitted to the outer periphery of the roller holding portion 62. An upper plate 66, a lower plate 68, and a link shaft 69 are fixedly connected to each other so as to connect the pair of rotating plates 64. The lower plate 68 has a magazine base 11 on the upper surface side.
And at the same height as the inner wall surface 11a, and in the state shown in FIG. 3, the slot 11b formed in the magazine base 11 is closed. Further, the link rod 24 is rotatably connected to the link shaft 69.

The tilting mechanism 20 configured as described above
It works as follows. First, when the tool pot 10 is transferred to the indexing position by the transfer mechanism 12, the positioning roller 36 of the tool pot 10 fits into the roller holding portion 62 of the positioning member 21, and at the same time, the transfer roller 38 of the tool pot 10 Rests on the lower plate 68.

Subsequently, when the link rod 24 is raised in this state, the turning member 22 turns, and the turning member 22 turns.
At the same time, the tool pot 10 also rotates to a replaceable state.
At this time, since the rotation center of the rotation member 22 is exactly on the same axis as the rotation center of the tool pot 10,
And the rotating member 22 do not rub strongly. In addition, as shown in FIG.
Is closed. Therefore, when the tool pot 10 is tilted, the movement of the bracket 18 in the transfer direction is restricted. Therefore, even if any external force is applied to the tool pot 10, for example, the tool pot 10 is not displaced in the transfer direction while the tool pot 10 is rotated to the exchangeable state. The pot 10 is maintained at a proper position.

After the tool pot 10 can be replaced, the tool changer (not shown) is operated to activate the tool T.
Is exchanged, and after this exchange is completed, when the link rod 24 is lowered, the rotating member 22 rotates, and the tool pot 10 rotates together with the rotating member 22 to the retracted state. With this rotation, the blocking of the lateral passage 62b of the positioning member 21 is released, and the bracket 18 can pass through. Therefore, thereafter, the transfer mechanism 1
2, the transfer of the tool pot 10 can be executed.

According to the tool pot 10 and the tilting mechanism 20 configured as described above, since the tool pot 10 is rotated by the rotating member 22 that rotates coaxially with the tool pot 10, the tool pot 10 and the tilting mechanism 20 are rotated. The moving member 22 rotates without being relatively displaced. Therefore, the tool pot 10 and the rotating member 22 do not rub strongly, and there is no need to arrange a roller or the like for suppressing friction between the two.

Accordingly, a roller to be mounted on each tool pot is provided in comparison with a conventional product in which a roller is disposed on a tool pot and the tool pot is tilted while the roller is held by a tilting mechanism. The number can be reduced. As a result, the number of parts of the tool pot is reduced, the structure is simplified, and the parts cost and the assembly cost can be reduced as compared with the conventional product.

The positioning roller 3 of the tool pot 10
6 is fitted into the roller holding portion 62 of the positioning member 21 to maintain the center of rotation of the tool pot 10 at a fixed position, so that the tool pot 10 is a relatively unstable structure such as the chain 16 and the bracket 18. Despite being supported by the tool pot, the tool pot 10 can be rotated in a sufficiently stable state.

Next, a drive source for operating the tilting mechanism 20 will be described. In this tool storage device 1,
As a driving source for operating the tilting mechanism 20, FIG.
(A), an air cylinder 70 shown in FIG. The air cylinder 70 has a first cylinder chamber 71.
And a first piston 7 slidable in the first cylinder chamber 71.
2 and a first piston rod 73 fixed to the first piston 72. Further, as a lock mechanism for locking the operation of the first piston 72, a second cylinder chamber 75 disposed on the side of the first piston rod 73 and a second piston slidable in the second cylinder chamber 75. 76,
A second piston rod 77 fixed to the second piston 76 and operable to a position where it engages with an engagement groove 73a formed in the first piston rod 73;
In the direction in which the second piston rod 7 comes into contact with the second piston 76 and engages with the first piston rod 73.
And a coil spring 78 that biases the coil spring 7.

A first intake / exhaust passage 81 communicates with one of the first cylinder chambers 71 defined by the first piston 72. Further, one of the second cylinder chambers 75 defined by the second piston 76 has a second cylinder chamber 75.
The intake / exhaust passage 82 communicates with the second cylinder chamber 75.
A third intake / exhaust passage 83 communicates from the middle position to the other chamber of the first cylinder chamber 71. The other chamber of the second cylinder chamber 75 is open to the atmosphere via a fourth intake / exhaust passage 84.

The air cylinder 70 constructed as described above
Is installed inside the actuator case 26 (see FIG. 1) in a state where the first piston rod 73 expands and contracts downward, and the link rod 24 of the tilting mechanism 20 is connected to the lower end side of the first piston rod 73. .

When the tool pot 10 is in the retracted state, as shown in FIG.
To introduce air into the first cylinder chamber 71. As a result, the first piston rod 73 and the first piston 72
Is lowered, the link rod 24 connected to the first piston rod 73 also moves downward as shown in FIG. 3, the rotating member 22 rotates counterclockwise in FIG. 3, and the tool pot 10 is retracted. Rotate to the state.

Here, when the tool pot 10 is in the retracted state, the center of gravity of the tool pot 10 is located on the side of the center of rotation of the tool pot 10. It is in a state of being constantly urged in the direction of turning to the tilt position. However, this air cylinder 70
In this case, when the first piston 72 reaches the bottom dead center, the second piston 76 biased by the coil spring 78 is displaced, and the second piston rod 77 is engaged with the engagement groove 73a. The piston rod 73 is locked so that it cannot be displaced.

Therefore, the tool pot 10 does not rotate to the tilting position due to its own weight. In particular, the first intake / exhaust passage 81 connects the first cylinder chamber 7
Even if the supply of air into 1 is cut off and the first piston 72 is not urged downward, the tool pot 10 can be easily maintained in the retracted state.

On the other hand, when the tool pot 10 is set in a replaceable state, as shown in FIG.
Air is introduced from the second into the second cylinder chamber 75. Thereby, the second piston 76 is displaced, the second piston rod 77 is disengaged from the engagement groove 73a, and the lock of the first piston rod 73 is released. Further, with the displacement of the second piston 76, the second cylinder chamber 75 and the first cylinder chamber 7
1 communicates via the third intake / exhaust passage 83, and air is introduced into the first cylinder chamber 71. As a result, the first piston rod 73 moves up together with the first piston 72, and the link rod 24 connected to the first piston rod 73 also moves upward as shown in FIG. The tool pot 10 turns clockwise until the tool pot 10 can be replaced.

When the tool pot 10 is in a replaceable state, since the center of gravity of the tool pot 10 is located below the center of rotation of the tool pot 10, the tool pot 10 is forced to rotate from the tilted position. Does not work. Therefore, the air cylinder 70 is not provided with a mechanism that locks the first piston rod 73 when the first piston 72 reaches the top dead center. As long as no action is taken, there is no risk of displacement to the stored state. Incidentally, if it is assumed that an external force or the like acts on the tool pot 10 and it is desired to maintain the exchangeable state more reliably, a similar lock mechanism may be provided on the top dead center side of the air cylinder 70. .

Although the embodiments of the present invention have been described above, various specific embodiments other than those described above are conceivable for the embodiments of the present invention. For example, the tool storage device 1 has a structure in which the tool pot 10 can rotate to either the storage state or the tool change state, but depending on the positional relationship with the tool change device or the structure of the transfer mechanism. However, it is not always necessary to configure the tool pot to be rotatable. Even in such a case, the structure in which the transfer mechanism holds the tool pot so that it can be attached and detached can reduce the labor required for mounting and removing the tool pot. The effect remains the same.

The tool storage device 1 is provided with a rotating shaft 34.
The tool pot 10 is held by the bracket 18 by fitting the tool pot into the first cutout 54. However, regarding the connection structure between the tool pot and the transfer mechanism,
The structure is not limited to the specific one described above, and various structures that can be freely attached and detached can be considered.

Further, the bracket 18 has the first cutout 54 shaped so that the toolpot 10 can be removed by simply moving the toolpot 10 in one direction. By forming a complicated shape such as bending, the tool pot 10 can be held in a state where it is harder to fall off.
