DESCRIPTION OF EMBODIMENTS

(9) Next, one embodiment of a movable stand with casters and a processing machine line according to the present disclosure will be described below with reference to the drawings. FIG. 1 is a perspective view illustrating the processing machine line of the present embodiment. In a processing machine line 10, six machine tools 1 that are installed on a base 2 are lined up. Each of the six machine tools 1 is an NC lathe of the same shape, and the internal structure, and entire form and dimensions are the same. In particular, the machine tool 1 is a compact machine body designed to have a small width dimension, and the entirety of the processing machine line 10 in which the machine tools 1 are closely disposed to each other is gathered to be compact.

(10) The machine tools 1 are all covered by an exterior cover 11, and a processing module that is constituted by a machine tool main body is internally provided. FIG. 2 is a perspective view illustrating a state in which each configuration of the processing machine line 10 is separated, and indicates a base 2, a processing module 3, and a control panel 5 that is omitted from FIG. 1. The processing module 3 indicates a state in which the exterior cover 11 is removed, and furthermore, theoretically, only one of the two processing modules 3 is installable on the base 2. Since two processing modules 3 correspond to one base 2, in the processing machine line 10 that is illustrated in FIG. 1, three bases 2 are lined up and six processing modules 3 are installed on the bases.

(11) Then, the processing modules 3 are configured on a movable bed 16 that is provided with wheels so that it is possible to move on the base 2 in the front-rear direction along straight line rails 401 provided separated with a gap in a width direction. A turret device that is provided with a main spindle stand or a tool that grasps a workpiece, a driving device that moves the turret device in the Z-axis and X-axis directions, a control device 17, and the like are installed on the movable bed 16. Consequently, in the machine tool 1, a tool is selected by revolving and indexing the turret device, positioning of the tool is carried out by driving an X-axis driving device and a Z-axis driving device, and cutting processing and the like are carried out on the workpiece that is rotated by driving of the main spindle.

(12) In addition, the machine tool 1 is provided with a workpiece conveyance device. The workpiece conveyance device carries out delivery of the workpiece to and from each of the processing modules 3, and is disposed inside a front cover 12 that is formed in front of the machine tool 1. A plurality of the front covers 12 constitute one cavity that is continuous in the width direction, and the workpiece conveyance device that is provided with a robot arm in the space is attached to the base 2 to be able to run. In the processing machine line 10 illustrated in FIG. 1, an internal conveyance space is formed, therein the workpiece conveyance device moves, and delivery of the workpiece to and from each of the machine tools is carried out.

(13) Furthermore, in the present embodiment, the control panel 5 is provided at a separate position from the machine tool 1. In particular, the control panel 5 is installed on the movable stand with casters 6 so as to be movable. Then, the control panel 5 is disposed to the rear of the machine tool 1 and connected to the processing module 3 side by a wiring 15. For example, the wiring 15 is a power cable for driving a servomotor for the main spindle and a servomotor for the X-axis and Z-axis driving devices, a communication cable that exchanges a signal for carrying out driving control, and the like.

(14) The control panels 5 on the processing machine line 10 are provided on each base 2, that is, with respect to two machine tools 1. Accordingly, as illustrated in FIG. 3, three control panels 5 are provided on the base 2 in three processing machine lines 10. FIG. 3 is a perspective view illustrating control panels 5 lined up at the rear of the processing machine line 10. A control device 17 of each of the processing modules 3 is indicated so as to be divided by a relationship with the machine tool 1. As exemplified, the processing modules 3 (control devices 17) are disposed to approach each other, and in the same manner, three control panels 5 are disposed to approach each other.

(15) Accordingly, during maintenance and the like, in a case where the control panels 5 are separated from the machine tools 1 and caused to move, normally, the control panels 5 are caused to move to the rear side as indicated by an arrow. However, as will be described, even in the problem, sufficient space is necessary to the rear of the processing machine line 10. Note that, in the related art, there are multiple folding tables with casters and the like that is indicated in PTL 1 having the same configuration as the movable stand with casters 6. The object of providing casters is to move to a storage location, and the folded table is stored in the storage location to be compact. That is, in the related art, the structure that is provided with the casters is simply for movement.

(16) In this point, since improvement of workability is achieved even in the present embodiment, movement of the control panels 5 becomes the object. However, in the structure that is simply for movement, it is not possible to sufficiently exhibit the effect of a small space in which a movement range is limited. Therefore, in the present embodiment, interference of the movable stand with casters 6 with each other is avoided, and the movable stand with casters 6 is suggested that is movable to slightly turn. Note that, the movable stands with casters 6 are hereinafter simply referred to as movable stands 6.

(17) In this arrangement, FIG. 4 to FIG. 6 are diagrams that indicate the movable stand 6 in a state in which the control panel 5 is installed, FIG. 4 is a side view, FIG. 5 is a front view in the front-rear direction, and FIG. 6 is a planar view. Note that, in the present embodiment, the machine tool 1 is referred to, a Z-axis direction that is indicated in FIG. 2 and FIG. 3 is described as the front-rear direction, the Y-axis direction is described as the width direction, and the X-axis direction is described as the height direction. The direction that indicates the description of the movable stand 6 and the conveyance jig 8 designates a direction in a state that is indicated in FIG. 2 and FIG. 3 of being disposed with respect to the machine tools 1 (processing machine line 10).

(18) The movable stand 6 is assembled in a predetermined shape in which multiple members configured with a rectangular steel pipe are joined to each other. Therefore, first, in the movable stand 6, the horizontal members 21 and 22 are disposed horizontal to a floor 200 that extends in the front-rear direction. Casters 25 are attached at both end sections to the front and rear of the horizontal members 21 and 22, and movement is possible in a state in which the control panel 5 is supported by a total of four casters 25. The horizontal members 21 and 22 are configured to be disposed in the width direction with a gap that matches the width dimension of the control panels 5, the length of the front-rear direction is longer than the dimensions of the control panels 5, and the casters 25 are positioned at positions that protrude to the front and rear in planar view. Consequently, the control panels 5 are disposed at a high position, but stabilized movement is possible by the casters 25 at four locations in both end sections of the horizontal members 21 and 22.

(19) Then, an auxiliary member 26 is joined to one horizontal member 21 so as to protrude downward with respect to both end sections, and the casters 25 are attached thereto. Accordingly, as illustrated in FIG. 4, the horizontal member 21 is disposed at a higher position from the floor 200 than the other horizontal member 22, and a height difference between both in the up-down direction is set such that there is a slight gap 100 in a case of viewing from the side. The movable stands 6 that are used by the processing machine line 10 are all the same, and in the case of disposing as indicated in FIG. 3, the positions of all movable stands 6 are aligned to the left and right of the horizontal members 21 and 22.

(20) Next, the horizontal members 21 and 22 are orthogonally joined to two leg members 27 respectively to the front and rear. The gap in the front-rear direction respectively of the two leg members 27 of the horizontal members 21 and 22 corresponds to the dimensions of the control panels 5. The length of the leg members 27 is set such that the height of the control panels 5 that are installed on the movable stands 6 are positioned for easy handling by the operator. Then, upper end portions of the standing four leg members 27 are connected at four sides by the beam members 31 and 32, and are configured by the top plate sections such that it is possible to install in a state in which the control panel 5 is fixed.

(21) Furthermore, the movable stands 6 are connected to both the left and right sides by a reinforcing member 23 at a lower part. The movable stands 6 are configured such that twisting of the leg members 27 that occurs during movement is suppressed by the reinforcing member 23 since the center of gravity is at a position of the casters 25, that is, a high position from the floor 200 due to the installed control panels 5. At that time, the reinforcing member 23 is joined horizontally. Therefore, a connecting member 28 that is at the same height as the horizontal member 21 is joined to the two leg members 27 that are joined to the horizontal member 22 side. Then, the reinforcing member 23 is joined to the horizontal member 21 at one end, and is joined to the connecting member 28 at the other end.

(22) Subsequently, as illustrated in FIG. 3, in the processing machine line 10 of the present embodiment, the control panels 5 are installed on the movable stands 6, and are disposed to the rear of the machine tools 1 (control devices 17). At this time, three control panels 5 and movable stands 6 are not only disposed closely to each other, but also at positions close to the machine tools 1. Accordingly, as described above, in a case where work such as maintenance is carried out by the operator at the rear of the machine tools 1, it is necessary to move the control panels 5 to secure a work space. In this arrangement, FIG. 7 is a planar view illustrating a simplification of movement of the control panels 5 by the movable stands 6 of the present embodiment. In particular, a case where the control panel 5 that is positioned in the center interposed to the left and right is moved is illustrated in comparison to a related art example.

(23) In a case where the control panel 5 is moved, the control panel 5 rotates to either one of the left or right (right side in FIG. 7) after being moved straight to the rear (upward in FIG. 7) as indicated by an arrow. The control panel 5 is rotated in order to be able to more widely secure a rear side space of the machine tool 1 that is the target. In addition, therefore it is possible to suppress the length of the wiring 15 by shortening the straight line distance from the processing module 3. Furthermore, therefore it is possible to set such that there is no hindrance to work by bringing the wiring 15 close to the rotation side. In particular, regarding the third point, the control panel 5 in the present embodiment determines that the rotation direction is to the right side since the wiring 15 comes out from the right side and extends to the processing module 3. Then, the movable stand 6 is designed such that the disposition of the horizontal members 21 and 22 matches the rotation direction. That is, the horizontal member 21 at the high position is designed so as to be positioned on the inside during rotation.

(24) Therefore, first, a movable stand 600 of the related art that is indicated by a dashed line has to be moved to a distant position as exemplified. Meanwhile, as indicated by a solid line, the movable stand 6 of the present embodiment is able to be moved to a closer position. Movement at this time is movement straight to the rear up to a position that does not overlap with the control panel 5 that is stationary next to the center control panel 5 viewed in the width direction (Y-axis direction), then next, rotated to the left side as indicated by an arrow. In the rotation step, each of the movable stands 6 that are adjacent to each other viewed in the width direction overlap with the horizontal members 21 and 22. However, in the present embodiment, since the horizontal member 21 at the rotation inner side is at a higher position than the horizontal member 22 of the movable stand 6 that is positioned adjacent by the gap 100, as illustrated in FIG. 8, it is possible to intersect the horizontal member 21 on the horizontal member 22.

(25) In this point, the movable stand 600 of the related art has generally the same configuration as described in PTL 1, and the heights of each of the left and right horizontal members that are provided with the casters are the same. Therefore, if the movable stand 600 does not retreat to a position so as not to overlap with the adjacent movable stand 600 viewed in the width direction, the movable stand 600 is not able to rotate, therefore the movable stand 600 comes away from the machine tool 1 up to the position that is indicated in FIG. 7. Consequently, a movement space is necessary at the rear of the processing machine line 10 by that amount.

(26) In contrast, according to the movable stand 6 of the present embodiment, a space to the rear of the processing machine line 10 may be small since each of the adjacent control panels 5 as described above may be caused to retreat to a deviated position viewed from the width direction (Y-axis direction) and rotated. Then, since the control panel 5 rotates and moves, the rear side space is released close to the machine tool 1, and improvement of workability of maintenance and the like is maintained by the operator. In addition, it is possible to shorten the length of the wiring 15 more than in the related art since the movement position of the control panel 5 from the machine tool 1 is close. Furthermore, the movable stand 6 is a low-cost one in which the members configured with a rectangular steel pipe are joined and moreover the effect is obtained by a simple configuration in which the height of the horizontal member 21 is increased by the auxiliary member 26.

(27) An embodiment of the present disclosure is described above, but the present disclosure is not limited thereto, and various modifications are possible within a range which does not depart from the gist of the present disclosure. For example, the members that constitute the movable stand 6 may not be the rectangular steel pipe and may be around steel pipe or another member. In addition, the leg member and the like may not be a steel pipe and may be a plate member.
