Description

[Technical Field]

[0001] The present invention relates to a multi-tasking machine equipped with a hole drilling device and a cutting device. [Background technology]

[0002] Patent Document 1 describes a multi-tasking machine that can perform drilling and cutting on long workpieces on a single line. The multi-tasking machine described in Patent Document 1 has, in order from the upstream side of the line, a drilling unit that drills holes in the workpiece and a cutting unit that cuts the workpiece, arranged closely together. A workpiece carrying-in device that supplies workpieces to the drilling unit is arranged upstream of the drilling unit, and a workpiece carrying-out device that carries out workpieces cut by the cutting unit is arranged downstream of the cutting unit. The workpiece carrying-in device and the workpiece carrying-out device are each long roller conveyors, and the workpiece is transported from the workpiece carrying-in device to the workpiece carrying-out device as a work transport path.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 7-108430 Summary of the Invention [Problem to be solved by the invention]

[0004] In a conventional multi-tasking machine such as that described in Patent Document 1, the drill unit is arch-shaped and can drill holes in a workpiece, such as an H-beam, from above and from the sides in the width direction. The cutting unit is a horizontal band saw that can cut the workpiece in a direction perpendicular to its longitudinal direction.

[0005] In conventional multi-tasking machines, the drilling unit and the cutting unit are arranged side by side in relatively close proximity. Therefore, setup and maintenance of the drilling unit are performed from the upstream side in the workpiece transport direction, and setup and maintenance of the cutting unit are performed from the downstream side. Furthermore, operations of the drilling unit and the cutting unit can be performed from a single operation panel. For example, the operation panel is located on the first side of the workpiece transport path on the downstream side of the cutting unit in the workpiece transport direction.

[0006] Therefore, for example, when the setup work for the drill unit is performed from the second side opposite to the first side of the work transport path, and then the setup work for the cutting unit or the operation of the control panel is performed on the first side of the work transport path, the worker must walk a long distance around the tip of the long work carry-in device or work carry-out device to get to the other side. This places a heavy burden on the worker, and there has been a need for a way to reduce the burden on the worker in operating and working on the multi-tasking machine. [Means for solving the problem]

[0010] Example 1 A multi-tasking machine 91, which is a first embodiment of the multi-tasking machine of the present invention, will first be described with reference to Figures 1 and 2. Figure 1 is a top view showing the overall configuration of the multi-tasking machine 91 of one embodiment of the present invention. Figure 2 is a perspective view showing the main body processing section 92 of the multi-tasking machine 91, seen diagonally from above and behind the left. In the following description, the front, back, left, and right directions are defined as the directions of the arrows shown in Figure 1. The top is the front of the page, and the bottom is the back of the page.

[0011] The multitasking machine 91 has a main body processing section 92, a carry-in table 93, an unloading table 94, and a material feeding unit 95. The carry-in table 93 is a roller table that is long in the front-to-rear direction, and is installed behind the main body processing section 92. The carry-in table 93 has a frame 931 and a plurality of rollers 932 that are rotatably supported by the frame 931. The material feeding unit 95 is installed adjacent to the carry-in table 93, and feeds a long workpiece W that has been transported from the outside and placed on the rollers 932 of the carry-in table 93 toward the main body processing section 92.

[0012] The material feeding unit 95 has a guide rail 954, a main body 951, an arm 952, and a clamper 953. The guide rail 954 is disposed adjacent to the frame 931 of the carry-in table 93 and supports the main body 951 so that it can move freely in the front-to-rear direction. The main body 951 moves on the guide rail 954 by a drive unit (not shown). One end of the arm 952 is connected to the main body 951, and the other end is equipped with a clamper 953. The clamper 953 grips the rear end of the workpiece W and transports the workpiece W forward as the main body 951 moves (see arrow DR1). The clamping operation of the clamper 953 and the movement of the main body 951 are controlled by a control device 3 provided in the main body processing section 92. The transport path of the workpiece W is indicated by a dot-dash line conveying line XL extending in the front-to-rear direction.

[0013] The main processing section 92 is installed on floor FL and includes a hole processing device 1, a cutting device 2, a control device 3, a partition unit 4, and an operation panel 5. The hole processing device 1, the cutting device 2, and the control device 3 are installed inside an isolation wall 41 that encloses the partition unit 4. The partition unit 4 has an opening / closing door 42 on the right side. The opening / closing door 42 is closed during processing, and when processing is stopped, a worker Hm (see FIG. 6) can open the opening / closing door 42 to enter and exit the partition unit 4.

[0014] The hole machining device 1 and the cutting device 2 are arranged in this order from the rear side on the conveyor line XL. That is, the workpiece W sent from the carry-in table 93 is first machined by the hole machining device 1, and then cut by the cutting device 2.

[0015] Inside the partition unit 4, the hole processing device 1 and the cutting device 2 are arranged so that their respective maintenance and inspection work surfaces 1F and 2F (surfaces marked with a ▲ in Figure 1) face each other, maintaining a predetermined distance D. The control device 3 is arranged along the left-hand wall. The maintenance and inspection work surfaces 1F and 2F will hereinafter also be referred to as work surface 1F and work surface 2F, respectively.

[0016] A long carry-out table 94 extending in the front-rear direction is installed on the front side of the cutting device 2. The carry-out table 94 has a frame 941 and a plurality of rollers 942 rotatably supported by the frame 941, and transports the material cut by the cutting device 2 forward.

[0017] In this example, the operation panel 5 is installed on the right rear surface of the isolation wall 41 of the partition unit 4. In other words, the operation panel 5 is located on the right side of the carry-in table 93.

[0018] Next, the hole machining device 1, cutting device 2, and operation panel 5 will be described with reference to Figures 3 to 5. Figure 3 is a front view of the hole machining device 1 provided in the main body processing unit 92, taken along the arrow Y3-Y3 line in Figure 2. Figure 4 is a rear view of the cutting device 2 provided in the main body processing unit 92, taken along the arrow Y4-Y4 line in Figure 2. Figure 5 is a perspective view of the operation panel 5 of the main body processing unit 92, seen obliquely from above and behind.

[0019] Fig. 3 is a view of the hole machining device 1 as seen from the work surface 1F side. A transport opening 14 is formed in the lower part of the center in the left-right direction of the hole machining device 1, and the rollers 932 of the carry-in table 93 are visible from the transport opening 14. In Fig. 3, the outline of the workpiece W placed on the rollers 932 is shown by a dashed line.

[0020] The hole machining device 1 is equipped with a gate-shaped frame 11 that surrounds a transport opening 14. The gate-shaped frame 11 has a left processing section 15L that performs hole machining from the left side of the workpiece W that has entered the hole machining device 1 through the transport opening 14, a right processing section 15R that performs hole machining from the right side, and an upper processing section 15V that performs hole machining from above.

[0021] The left machining unit 15L has a left spindle 12L to which a tool 81 is detachably attached, a left spindle drive unit 12KL to rotate the left spindle 12L, and a left automatic tool changer 13L to automatically attach, detach, and replace the tool 81 to the left spindle 12L. The right machining unit 15R has a right spindle 12R to which a tool is detachably attached, a right spindle drive unit 12KR to rotate the right spindle 12R, and a right automatic tool changer 13R to automatically attach, detach, and replace the tool 81 to the right spindle 12R. The upper machining unit 15V has an upper spindle 12V to which a tool 81 is detachably attached, an upper spindle drive unit 12KV to rotate the upper spindle 12V, and an upper automatic tool changer 13V to automatically attach, detach, and replace the tool 81 to the upper spindle 12V.

[0022] The operations of the left processing unit 15L, the right processing unit 15R, and the upper processing unit 15V are controlled by the control device 3. In addition, operations such as setting tools 81 and maintenance for the left processing unit 15L, the right processing unit 15R, and the upper processing unit 15V can be performed from the work surface 1F side shown in FIG.

[0023] 4 is a view of the cutting device 2 as seen from the work surface 2F side. A transport opening 22 is formed in the lower part of the center in the left-right direction of the cutting device 2, and the rollers 942 of the carry-out table 94 are visible from the transport opening 22. In FIG. 4, the outline of the workpiece W placed on the rollers 942 is indicated by a dashed line.

[0024] The cutting device 2 is a horizontal band saw machine and has a cutting head 21 that can be raised and lowered. The cutting head 21 has a frame 211, a drive wheel 212, a driven wheel 213, a drive motor 214, a lifting motor 215, and a band saw blade 216. The drive wheel 212 is rotated by the drive motor 214, and an endless band saw blade 216 is stretched between the drive wheel 212 and the driven wheel 213. The lifting motor 215 raises and lowers the cutting head 21 (see arrow DR2). As a result, the workpiece W is cut by lowering the cutting head 21 from the standby position shown in FIG. 4 by the lifting motor 215 while the drive motor 214 is operating to run the band saw blade 216.

[0025] The operation of the cutting device 2 is controlled by the control device 3. Furthermore, replacement and maintenance of the band saw blade 216 can be performed from the side of the work surface 2F shown in FIG.

[0026] 5, the operation panel 5 is installed on the outer surface of the separation wall 41 of the partition unit 4, to the right of the carry-in table 93. The operation panel 5 has an operation unit 51 for operating the entire multi-tasking machine 91 including the hole processing device 1 and the cutting device 2, and a display unit 52 for displaying the operating status and processing content of the multi-tasking machine 91.

[0027] Next, the line of movement Rt1 of the worker Hm in the main body processing section 92 will be described with reference to Fig. 6. Fig. 6 is a top view for explaining the line of movement Rt1 of the worker Hm in the multi-tasking machine 91.

[0028] As described above, a predetermined distance D is maintained between the hole drilling device 1 and the cutting device 2. The distance D between the work surfaces 1F and 2F, marked with the symbol ▲, is set to at least allow the worker Hm to walk between the hole drilling device 1 and the cutting device 2, and is set to, for example, 60 cm. Opposite maintenance and inspection work surfaces are located at the symbols ▼ and ▲. As a result, in FIG. 6, a work area AR1, which is a roughly rectangular shape elongated from side to side and marked with dashed hatching, is defined as the floor area between the hole drilling device 1 and the cutting device 2, and a work space V1 extending upward within that area is secured, allowing the worker Hm to work on the opposite maintenance and inspection work surfaces.

[0029] Example 2 A multi-tasking machine 91A, which is a second embodiment of the multi-tasking machine of the present invention, will now be described. The multi-tasking machine 91A is equipped with a cutting device 2A capable of performing oblique cutting by rotating the cutting head 21, instead of the cutting device 2 of the multi-tasking machine 91 of the first embodiment. The multi-tasking machine 91A will be described below with reference to FIGS. 7 and 8. FIG. 7 is a perspective view of the main body processing section 92A of the modified multi-tasking machine 91A, viewed obliquely from above and behind the left. FIG. 8 is a top view illustrating the movement line Rt2 of an operator Hm in the multi-tasking machine 91A.

[0030] As shown in FIG. 7, the multitasking machine 91A has the same input table 93, output table 94, and hole machining device 1 as the multitasking machine 91. The cutting device 2A has a cutting head 21A that can rotate at a predetermined angle θa around a vertical rotation axis CL2A. The maximum value of the angle θa is, for example, 45°. At the rotation position where the angle θa is 0°, which is the cutting reference position, the cutting surface is perpendicular to the conveying line XL, and when the angle θa is 45°, the cutting surface is inclined at 45° with respect to the conveying line XL. The hole machining device 1 and the cutting device 2A are arranged so that their respective maintenance and inspection work surfaces 1F and 2AF face each other.

[0031] Partition unit 4A, which corresponds to partition unit 4, has a partition wall 41A and an opening / closing door 42A corresponding to partition wall 41 and opening / closing door 42 of partition unit 4, respectively. When opening / closing door 42A is in the open position, the hole drilling device 1 and the cutting device 2 are not automatically operated and are in a maintenance / inspection work mode. Since worker Hm enters the work area AR1 between the hole drilling device 1 and the cutting device 2 after the maintenance / inspection work mode is entered, the safety of worker Hm is ensured. In partition unit 4A, the front wall of partition wall 41A is partially open so that the right end of cutting head 21A does not interfere when it rotates. In addition, extension wall 43A is provided to protrude forward so as to surround the rotated cutting head 21A.

[0032] In the multi-tasking machine 91A, the pivot axis CL2A of the cutting device 2A is set at the intersection of the transfer line XL, which passes through the fixed vise reference of the cutting device, and the travel path of the band saw blade with the tooth tip facing the material. Therefore, when the cutting head 21A pivots by an angle θa, the left end of the cutting head 21A moves rearward and approaches the hole drilling device 1, and the right end moves forward and away from the hole drilling device 1. As a result, the working area on the floor is the working area AR2, which is hatched with a dashed line in Figure 8. In other words, the working area AR2 is trapezoidal, and the multi-tasking machine 91A has a working space V2 that extends upward from this working area AR2.

[0033] In this work space V2, worker Hm can be both worker Hm1 working on the work surface 1F of the hole drilling device 1 and worker Hm2 working on the work surface 2AF of the cutting device 2A, all in the same work space V2. The length of the movement line Rt2 between the work space V2 and the standing position of worker Hm5, who operates the control panel 5, is an extremely short distance that essentially follows the surface of the isolation wall 41A of the partition unit 4A by opening the opening / closing door 42A, without having to go around the carry-in table 93 or the carry-out table 94.

[0034] As a result, when using the multi-tasking machine 91A, the worker Hm only needs to move a very short distance when alternating between working on the hole processing device 1 and the cutting device 2A and operating the control panel 5, thereby reducing the burden on the worker Hm in operating and working on the multi-tasking machine 91A.

[0035] In Examples 1 and 2, worker Hm can be in both positions: worker Hm1 working on work surface 1F of hole drilling device 1, and worker Hm2 working on work surfaces 2F, 2AF of cutting devices 2, 2A, while being in the same work spaces V1, V2. It is possible to imagine movement lines Rt1, Rt2 in which worker Hm operates control panel 5 to move to work spaces V1, V2. Conventionally, worker Hmp (dashed line) would circle around carry-out table 94 (or carry-in table 93) indicated by movement line Rtp (dashed line) to work on the maintenance and inspection work surface indicated by symbol ▽ (dashed line). However, by securing work spaces V1, V2 and obtaining movement lines Rt1, Rt2, the length of movement line Rtp is effectively extremely short.

[0036] In this way, the worker Hm only needs to move a very short distance when alternately performing work on the hole processing device 1 and cutting device 2, 2A and operating the operation panel 5, thereby reducing the burden on the worker Hm in operating and performing work related to the multi-tasking machines 91, 91A.

[0037] One aspect of the present invention is not limited to the above-described configuration and procedure, and modifications may be made without departing from the spirit of the present invention.

[0038] The order in which the hole drilling device 1 and the cutting device 2 (2A) are installed on the conveying line XL may be reversed. That is, although the example in which the hole drilling device 1 is installed on the upstream side has been described, the cutting device 2 (2A) may also be installed on the upstream side.

[0039] The installation location of the control panel 5 is not limited to the above-mentioned location. It may be installed in another location or independently, without being installed on the isolation wall 41 of the partition unit 4. Even in these cases, if the control panel 5 is installed on the same side of the transfer line XL as the opening and closing door 42 (42A) of the partition unit 4 (4A), the traffic lines Rt1 and Rt2 do not cross the transfer line XL and are therefore shorter, thereby reducing the burden on workers.

[0040] Although the partition unit 4 (4A) has been described as having the door 42 (42A) on one side of the transfer line XL, it may be provided on both sides. In this case, the worker Hm can open the door 42 (42A) to enter and exit the first side and the opposite second side of the transfer line XL. Furthermore, regardless of whether the operation panel 5 is located on the first side or the second side of the transfer line XL, the movement lines Rt1 and Rt2 are shortened, thereby reducing the burden on the worker.

[0041] The cutting device 2 is not limited to a band saw, but may be a circular saw.

[0042] As described above in detail, one embodiment of the multi-tasking machine of the present invention is installed on a conveying line XL and comprises a hole processing device 1 that performs hole processing on a long workpiece W that is being conveyed, and a cutting device 2 that performs cutting processing, and the hole processing device 1 and the cutting device 2 are arranged side by side with their respective maintenance and inspection work surfaces 1F, 2F facing each other and spaced apart at a distance D that allows a worker Hm to walk between them.

[0043] In this embodiment, the work surfaces 1F and 2F of the hole processing device 1 and cutting device 2 face each other, allowing the worker to enter between them and operate and work on both devices, which significantly reduces the worker's travel distance and reduces the burden on the worker.

[0044] Furthermore, each embodiment has in common that it is equipped with a partition unit 4 that encloses the hole processing device 1 and the cutting device 2 and has an opening and closing door 42 that allows access inside and outside, and when the opening and closing door 42 is open, it is not possible for the device to operate automatically.

[0045] This ensures the safety of the worker Hm.

[0046] Furthermore, in common with each aspect, the worker Hm may be able to perform work on the maintenance and inspection work surface 1F of the hole processing device 1 and the maintenance and inspection work surface 2F of the cutting device 2 from the same standing position.

[0047] This reduces the burden on the worker Hm.

[0048] Furthermore, in common with each embodiment, the cutting device 2 may be a horizontal band saw.

[0049] This allows for better cutting with less cutting resistance even in cutting processes with large cutting areas.

[0050] Furthermore, the cutting device 2 may include a cutting head 21A that allows the band saw blade 216 to travel and is capable of pivoting from a cutting reference position.

[0051] This allows the operator Hm to perform work on the hole machining device 1 and the cutting device 2A in the same workspace V2, while using part of the workspace V2 as a turning area for one end of the cutting head 21A, thereby improving the efficiency of use of the internal space of the main body processing part 92A.
