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 capable of drilling and cutting a long workpiece in one line. In the multi-tasking machine described in Patent Document 1, a drill unit that drills holes in the workpiece and a cutting unit that cuts the workpiece are arranged in close proximity to each other, starting from the upstream side of the line. A work carry-in device that supplies the workpiece to the drill unit is arranged upstream of the drill unit, and a work unloading device that unloads the workpiece cut by the cutting unit is arranged downstream of the cutting unit. The work carry-in device and the work unloading device are each a long roller conveyor, and the workpiece is transported from the work carry-in device, which serves as a work transport path, to the work unloading device.

[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 multitasking 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-shaped steel, from above and from the sides in the width direction. The cutting unit is a horizontal band saw and can cut the workpiece in a direction perpendicular to its longitudinal direction.

[0005] In conventional multi-tasking machines, the drill unit and the cutting unit are arranged side by side in relatively close positions. Therefore, the setup and maintenance of the drill unit are performed from the upstream side in the work transport direction, and the setup and maintenance of the cutting unit are performed from the downstream side. In addition, the drill unit and the cutting unit can be operated from a single operation panel. The operation panel is arranged, for example, on the first side of the work transport path on the downstream side in the work transport direction of the cutting unit.

[0006] Therefore, for example, when the setup work of the drill unit is performed from the second side opposite to the first side of the work transport path, and then the setup work of the cutting unit or the operation of the operation 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 loading device or the work unloading device to get to the other side. Therefore, the burden on the worker is large, and there has been a demand for a device that reduces the burden on the worker in operating and working on the multi-tasking machine. [Means for solving the problem]

[0007] In order to solve the above problems, one aspect of the multi-tasking machine of the present invention is installed on a conveying line and is equipped with a hole processing device that performs hole processing and a cutting device that performs cutting processing on the long workpiece being conveyed, and the hole processing device and the cutting device are arranged side by side with their respective maintenance and inspection work surfaces facing each other and spaced apart so that an operator can walk between them. Effect of the Invention

[0008] According to one aspect of the multi-tasking machine of the present invention, the burden on an operator in operation and work is reduced. [Brief description of the drawings]

[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 a main body processing section 92 of the multi-tasking machine 91, seen diagonally from above and behind on 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 paper and the bottom is the back of the paper.

[0011] The multi-tasking 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 on the rear side of 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 feed 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 as to be movable in the front-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 provided 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 as a transport line XL, which is a dashed line extending in the front-rear direction.

[0013] The main body 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 and closing door 42 on the right side. The opening and closing door 42 is closed during processing, and when processing is stopped, a worker Hm (see FIG. 6) can open the opening and 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 transfer 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 with their respective maintenance and inspection work surfaces 1F and 2F (surfaces marked with ▲ in FIG. 1) facing each other, with a predetermined distance D maintained between them. The control device 3 is arranged along the left side wall. The maintenance and inspection work surfaces 1F and 2F are hereinafter also referred to as work surface 1F and work surface 2F, respectively.

[0016] An output table 94 that is long in the front-rear direction is installed on the front side of the cutting device 2. The output table 94 has a frame 941 and a plurality of rollers 942 rotatably supported by the frame 941, and transports the member 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. That is, the operation panel 5 is located to the right of the carry-in table 93.

[0018] Next, the hole machining device 1, the cutting device 2, and the operation panel 5 will be described with reference to Fig. 3 to Fig. 5. Fig. 3 is a front view taken along the arrow Y3-Y3 in Fig. 2, showing the hole machining device 1 provided in the main body processing unit 92. Fig. 4 is a rear view taken along the arrow Y4-Y4 in Fig. 2, showing the cutting device 2 provided in the main body processing unit 92. Fig. 5 is a perspective view showing 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 faced from the transport opening 14. In Fig. 3, the outline of the workpiece W placed on the rollers 932 is indicated by a dashed line.

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

[0021] The left machining unit 15L has a left spindle 12L on which a tool 81 is detachably attached, a left spindle drive unit 12KL that rotates the left spindle 12L, and a left automatic tool change unit 13L that automatically performs attachment, detachment, and replacement of the tool 81 to the left spindle 12L. The right machining unit 15R has a right spindle 12R on which a tool is detachably attached, a right spindle drive unit 12KR that rotates the right spindle 12R, and a right automatic tool change unit 13R that automatically performs attachment, detachment, and replacement of the tool 81 to the right spindle 12R. The upper machining unit 15V has an upper spindle 12V on which a tool 81 is detachably attached, an upper spindle drive unit 12KV that rotates the upper spindle 12V, and an upper automatic tool change unit 13V that automatically performs attachment, detachment, and replacement of 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, the setting of tools 81 for the left processing unit 15L, the right processing unit 15R, and the upper processing unit 15V, and maintenance work can be performed from the work surface 1F side shown in FIG.

[0023] Fig. 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 faced 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 driving wheel 212, a driven wheel 213, a driving motor 214, a lifting motor 215, and a band saw blade 216. The driving wheel 212 is rotated by the driving motor 214, and an endless band saw blade 216 is stretched between the driving 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 cutting head 21 is lowered by the lifting motor 215 from the standby position shown in FIG. 4 while the driving motor 214 is operated to run the band saw blade 216, thereby cutting the workpiece W.

[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 work surface 2F side shown in FIG.

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

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

[0028] As described above, a predetermined distance D is secured between the hole processing device 1 and the cutting device 2. The distance D between the work surface 1F and the work surface 2F marked with the symbol ▲ is set so that at least the worker Hm can walk between the hole processing device 1 and the cutting device 2, and is set to, for example, 60 cm. Maintenance and inspection work surfaces are arranged opposite to each other at the symbols ▼ and ▲. As a result, in FIG. 6, a work area AR1 of a substantially rectangular shape long from side to side marked with dashed line hatching is set as a floor area between the hole processing device 1 and the cutting device 2, and a work space V1 extending upward is secured in that area, and the worker Hm can work on the maintenance and inspection work surfaces arranged opposite to each other.

[0029] Example 2 A multi-tasking machine 91A, which is a second embodiment of the multi-tasking machine of the present invention, will be described. The multi-tasking machine 91A is equipped with a cutting device 2A capable of performing oblique cutting by rotating a 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 showing a main body processing section 92A of the modified multi-tasking machine 91A, as seen obliquely from above and behind the left. Fig. 8 is a top view for explaining a movement line Rt2 of an operator Hm in the multi-tasking machine 91A.

[0030] As shown in FIG. 7, the multitasking machine 91A includes the same carry-in table 93, carry-out table 94, and hole processing 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 vertically extending rotation axis CL2A. The maximum value of the angle θa is, for example, 45°. At a 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 by 45° to the conveying line XL. The hole processing device 1 and the cutting device 2A are arranged so that their respective maintenance and inspection work surfaces 1F and 2AF face each other and 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 open, hole processing device 1 and cutting device 2 are not automatically operated and are in a maintenance and inspection work mode. Since worker Hm enters working area AR1 between hole processing device 1 and cutting device 2 after the maintenance and 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 turns. In addition, extension wall 43A is provided to protrude forward so as to surround turning cutting head 21A.

[0032] In the multi-tasking machine 91A, the turning axis CL2A of the cutting device 2A is set at the intersection of the conveying line XL passing through the fixed vice reference of the cutting device and the running line of the band saw blade with the tooth tip facing the material side. Therefore, when the cutting head 21A turns by the angle θa, the left end of the cutting head 21A moves backward and approaches the hole processing device 1, and the right end moves forward and away from the hole processing device 1. Therefore, the working area on the floor becomes the working area AR2 hatched with a dashed line in FIG. 8. In other words, the working area AR2 is trapezoidal, and the multi-tasking machine 91A secures a working space V2 by extending the working area AR2 upward.

[0033] In this work space V2, the worker Hm can be both the worker Hm1 working on the work surface 1F of the hole machining device 1 and the worker Hm2 working on the work surface 2AF of the cutting device 2A, while being in the same work space V2. The length of the movement line Rt2 along which the worker Hm moves between the work space V2 and the standing position of the worker Hm5 who operates the operation panel 5 is, by opening the opening and closing door 42A, an extremely short distance that essentially follows the surface of the isolation wall 41A of the partition unit 4A, without going 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 operation panel 5, thereby reducing the burden on the worker Hm in operating and performing tasks related to the multi-tasking machine 91A.

[0035] In the first and second embodiments, the worker Hm can be in the same work space V1, V2 as the worker Hm1 working on the work surface 1F of the hole processing device 1 and the worker Hm2 working on the work surfaces 2F, 2AF of the cutting devices 2, 2A. The worker Hm can be assumed to move from the operation panel 5 to the work space V1, V2 along lines of movement Rt1, Rt2. Conventionally, the length of the line of movement Rtp of the worker Hmp (dashed line) which goes around the carry-out table 94 (or the carry-in table 93) indicated by the line of movement Rtp (dashed line) to work on the maintenance and inspection work surface indicated by the symbol ▽ (dashed line) is substantially extremely short by obtaining the lines of movement Rt1, Rt2 by securing the work spaces V1, V2.

[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 the 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 configurations and procedures, and may be modified within the scope of the present invention.

[0038] The order of installation of the hole drilling device 1 and the cutting device 2 (2A) 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 be installed on the upstream side.

[0039] The installation position of the operation panel 5 is not limited to the above-mentioned position. 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 operation panel 5 is installed on the same side of the transport line XL as the opening and closing door 42 (42A) of the partition unit 4 (4A), the traffic lines Rt1, Rt2 do not cross the transport line XL and are therefore shorter, reducing the burden on the workers.

[0040] Although an example has been described in which the partition unit 4 (4A) has the opening and closing door 42 (42A) on one side of the transport line XL, it may be provided on both sides. In this case, the worker Hm can open the opening and closing door 42 (42A) to enter and exit the first side and the opposite second side of the transport line XL. In addition, regardless of whether the operation panel 5 is disposed on the first side or the second side of the transport line XL, the traffic 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 is equipped with a hole processing device 1 which performs hole processing and a cutting device 2 which performs cutting processing on a long workpiece W which is being conveyed, 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 D so that an operator Hm can walk between them.

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

[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 / closing door 42 that allows access inside and outside, and automatic operation is not possible when the opening / closing door 42 is in the open state.

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

[0046] Furthermore, in common to 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 to all the embodiments, 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] According to this, while a part of the working space V2 is used as a turning area for one end of the cutting head 21A, the worker Hm can perform the work on the hole processing device 1 and the cutting device 2A in the same working space V2. Therefore, the internal space utilization efficiency of the main body processing part 92A is improved. [Explanation of symbols]
