Description

[Technical field]

[0001] The present invention relates to an industrial machine, a workpiece processing method, and a rotating table device. [Background technology]

[0002] Machine tools with a swivel table are known (see, for example, JP 2000-024866 A). The swivel table used in this type of machine tool is, for example, a two-position swivel table, and is installed between the transfer chamber and the machining chamber. The swivel table rotates 180 degrees. The swivel table indexes either position 1 or position 2 into the machining chamber, and the other into the transfer chamber. At both position 1 and position 2, the same jig is arranged rotationally symmetrically with respect to the rotation axis of the swivel table.

[0003] In the above conventional machine tools, while a workpiece (material) is being machined in the machining chamber, an operator removes the machined workpiece (product) from the transfer chamber and sets a new material in the jig. Then, once machining is complete, the rotating table rotates 180 degrees and the machine tool repeats the same machining. Therefore, conventional machine tools improve the production volume per unit time of products, making them suitable for mass production of a small variety of products. Summary of the Invention [Problem to be solved by the invention]

[0004] However, the conventional machine tools require an operator to work in the transfer chamber at all times, so labor saving is not possible. Furthermore, when machining a wide variety of workpieces in small quantities, the machine tool must be stopped and the operator must replace the jig with a new one every time the type of workpiece changes. Therefore, the production volume per unit time is low considering the labor required by the operator. Therefore, the conventional machine tools are not suitable for high-mix low-volume production.

[0005] The present invention has been made in consideration of the above-mentioned circumstances, and its object is to provide a new industrial machine, a workpiece processing method, and a rotating table device that can reduce the labor required and are suitable for small-lot, multi-product production. [Means for solving the problem]

[0006] In order to achieve the above object, a first aspect of the present invention provides a processing system comprising a first chamber for processing a workpiece, an attachment / detachment tool provided in the first chamber for detachably holding the workpiece, a working tool provided in the first chamber for processing the workpiece, a second chamber adjacent to the first chamber, and a rotating table disposed between the first chamber and the second chamber and rotating about a rotating axis, the rotating table having a first area in which a first stocker for exclusively storing the workpiece before processing and a second stocker for exclusively storing the workpiece after processing are provided, and a second area in which a jig for holding the workpiece is provided. Among the first stocker and the second stocker, at least the bottom of the second stocker is formed in a staircase shape with a plurality of steps, The height of each of the steps is lower than the height of the workpiece, and when the processed workpieces are arranged on the steps, the processed workpieces are placed so as to regulate each other. It is an industrial machine.

[0007] Here, in the present invention, processing a workpiece means performing some kind of physical processing on the workpiece, and includes, for example, machining, cleaning, deburring, etc. Furthermore, the working tool in the present invention is any tool capable of processing the workpiece, and includes, for example, tools such as drills and water jet nozzles. Therefore, in the present invention, industrial machinery means a machine in a broad sense that can process a workpiece, and includes all kinds of machines and devices, such as machine tools, cleaning machines, and deburring devices.

[0008] The second aspect of the present invention is as follows: 7a fourth step of processing the workpiece placed on the jig with the work tool; a fifth step of holding the processed workpiece with the tool; and a sixth step of indexing the first area of ​​the swivel table to the first chamber and storing the processed workpiece held by the tool in the second stocker.

[0009] A third aspect of the present invention provides a method for manufacturing a workpiece processing system comprising: a rotating table; and a rotating mechanism for rotating the rotating table about a rotating axis, the rotating table having a first area in which a first stocker for exclusively storing unprocessed workpieces and a second stocker for exclusively storing the processed workpieces are installed; and a second area in which a jig for holding the unprocessed workpieces is installed. Among the first stocker and the second stocker, at least the bottom of the second stocker is formed with a plurality of steps in a staircase shape, the height of each step is lower than the height of the workpiece, and when the processed workpieces are arranged on the steps, the processed workpieces are placed so as to regulate each other. This is a rotating table device. Effect of the Invention

[0012] (Embodiment 1) Hereinafter, as an example of an embodiment of an industrial machine according to the present invention, a case where a workpiece is machined by a machine tool will be described with reference to the drawings. Fig. 1 is a side view of a machine tool 1 of embodiment 1. Fig. 2 is a perspective view of a swivel table 40 of embodiment 1, and Fig. 3 is a plan view of the swivel table 40 of embodiment 1. In this specification, a workpiece before machining (before processing) is defined as a "material", a workpiece after machining (after processing) as a "product", and a workpiece in the middle of machining (in the middle of processing) as a "semi-finished product", and these terms are used.

[0013] As shown in FIG. 1, the machine tool 1 includes a processing chamber (first chamber) 15, a stocker chamber (second chamber) 10, a shutter 13, a rotation mechanism 30, a rotating table 40, and a stocker. (First Stocker) 50 and Stocker (Second Stocker) 60, jigs 90, 91, a spindle head 21, a spindle 22, a spindle head moving device 23, an automatic tool changer (ATC) 24, a tool (work implement) 25, an attachment / detachment tool 26, and a control panel 7.

[0014] The machine tool 1 is a vertical machine tool. Of course, as described above, the present invention is applicable to all kinds of industrial machines, for example, machine tools such as horizontal machine tools, machining centers, grinding machines, and hobbing machines, as well as cleaning machines and deburring devices.

[0015] The spindle head moving device 23 freely moves the spindle head 21 in the left-right direction (X-axis), front-back direction (Y-axis), and up-down direction (Z-axis). The spindle 22 is journaled on the spindle head 21. The tool 25 or attachment / detachment tool 26 is attached to a spindle hole (not shown) of the spindle 22 by the automatic tool changer 24. The tool 25 is, for example, a face milling cutter, an end mill, a drill, or a tap.

[0016] The attachment / detachment tool 26 is, for example, a suction tool or a gripping tool. When the attachment / detachment tool 26 is attached to the main shaft 22, the main shaft 22 can attach / detach and hold the material 70 or the product 71 (including semi-finished products). Note that, for example, the device disclosed in Japanese Patent No. 6499063 can be used as the attachment / detachment tool 26.

[0017] The swivel table 40 is, for example, a two-position swivel table, and is installed between the processing chamber 15 and the stocker chamber 10. The swivel table 40 rotates 180 degrees about a swivel shaft 41. The swivel shaft 41 extends in the vertical direction (Z-axis direction) on the boundary between the processing chamber 15 and the stocker chamber 10.

[0018] 2 and 3, the swivel table 40 has two areas 40a and 40b and a movable wall 42. The movable wall 42 divides the swivel table 40 into a first area 40a and a second area 40b.

[0019] The first area 40a and the second area 40b are arranged with 180 degree rotational symmetry around the turning axis 41. By turning the turning table 40, one of the two areas 40a, 40b (two positions) is indexed to the processing chamber 15, and the other is indexed (positioned) to the stocker chamber 10.

[0020] The movable wall 42 is a flat plate. The movable wall 42 is fixed to the swivel table 40 on a plane that includes the swivel shaft 41 and is perpendicular to the swivel table 40. The movable wall 42 rotates integrally with the swivel table 40 around the swivel shaft 41. When the swivel table 40 is positioned, the movable wall 42 comes into contact with the shutter 13 (see FIG. 1), and the processing chamber 15 and the stocker chamber 10 are separated by the movable wall 42 and the shutter 13. The shutter 13 is, for example, a sliding door.

[0021] The rotation mechanism 30 rotates the swivel table 40 about a swivel shaft 41. The rotation mechanism 30 includes a motor as a drive source, a reducer, and the like.

[0022] The stocker 50 stores the raw material 70. The stocker 60 stores the product 71. That is, in the first embodiment, the raw material 70 and the product 71 are stored separately. The raw material 70 and the product 71 are, for example, rectangular flat plates. The raw material 70 and the product 71 may be, for example, disk-shaped or block-shaped.

[0023] The stocker 50 is disposed in the first area 40 a of the swivel table 40 via a support base 45 .

[0024] The stocker 50 includes a pair of side walls 51 and 52, a partition 53, a rail 54, and a fixture 55. One side wall 51 is, for example, a flat plate and is fixed to the support base 45. The rail 54 is fixed to the support base 45. The rail 54 has an elongated hole 54a. The other side wall 52 is attached to the rail 54 via an L-shaped bracket 57 and slides on the rail 54. The fixture 55 fixes the bracket 57 to an arbitrary position on the rail 54. The fixture 55 is, for example, a bolt. The fixture 55 is inserted into the elongated hole 54a of the rail 54 to fasten the rail 54 and the bracket 57 together, whereby the side wall 52 is positioned on the rail 54. The side wall 52 is slid on the rail 54, and the distance between the side walls 51 and 52 is adjusted to match the length of the material 70, so that a plurality of materials 70 can be stacked and stored between the side walls 51 and 52. The partition 53 is provided integrally with the side walls 51, 52, and prevents the material 70 from falling off, or maintains adjacent materials 70 at an interval.

[0025] A gap 56 is provided between the bottom of the side walls 51, 52 and the support base 45 (see FIG. 4). This gap 56 is larger than the plate thickness t of the material 70 and smaller than twice the plate thickness t (t<gap 56<2t). In other words, the gap 56 is large enough to allow one piece of material 70 to pass through.

[0026] The stocker 60 is disposed in the second area 40b of the swivel table 40 via a support base 46.

[0027] The stocker 60 includes a plurality of support columns 61 and a partition section 62. The support columns 61 are fixed to the support base 46. The support columns 61 are, for example, L-shaped members (angles). The distance between the support columns 61 is designed in advance to match the length of the products 71, and the products 71 are stored in a stacked state between the support columns 61. The partition section 62 is provided integrally with the support columns 61, and prevents the products 71 from falling or keeps adjacent products 71 spaced apart.

[0028] The extrusion device 80 is provided near the stocker 50. The extrusion device 80 extrudes the materials 70 stored in a stacked manner in the stocker 50 one by one. Details of the extrusion device 80 will be further described with reference to Figs. 4 and 5. Fig. 4 is a cross-sectional view taken along line IV-IV in Fig. 3, showing the configuration of the extrusion device 80, and Fig. 5 is an explanatory diagram of the operation of the extrusion device 80 of the first embodiment.

[0029] The extrusion device 80 includes an extrusion plate 81 and a fluid cylinder 83. The thickness of the extrusion plate 81 may be such that it can be inserted into the gap 56 of the stocker 50 and is equal to the thickness t of the material 70. The tip of the extrusion plate 81 is disposed facing the gap 56. The fluid cylinder 83 is provided on the rear side of the support base 45, and reciprocates the rod 84 by means of a working fluid. For example, an air cylinder can be used as the fluid cylinder 83. The working fluid in this case is compressed air. The tip of the rod 84 is connected to a bent portion 82 of the extrusion plate 81. As the rod 84 extends and retracts, the extrusion plate 81 reciprocates along the in-plane direction of the support base 45.

[0030] When rod 84 retracts in the direction of arrow A from its extended state (FIG. 4), pusher plate 81 enters stocker 50 through gap 56 and pushes out one piece of blank 70, as shown in FIG. 5. Since gap 56 is slightly larger than the thickness of blank 70, the pushed out blank 70 moves to blank storage area 48.

[0031] The material storage area 48 is an area defined by a stopper 85, a partition member (rib) 86, and rails 54 on the surface of the support base 45. The material storage area 48 is formed to have approximately the same outer shape as the material 70. That is, the length and width of the material 70 and the shape of the area of ​​the material storage area 48 are approximately the same. Therefore, the material 70 pushed out by the pusher plate 81 collides with the stopper 85 while being guided by the partition member 86 and the rails 54, and is placed in the correct position without falling from the material storage area 48.

[0032] The material 70 moved to the material storage area 48 is held by the attachment / detachment tool 26, set in jigs 90 and 91, and then processed.

[0033] The jigs 90 and 91 are disposed in the second area 40b of the swivel table 40. The jigs 90 and 91 can hold different types of material 70. The jigs 90 and 91 can have a suitable configuration depending on the shape of the material 70, etc. The jigs 90 and 91 are, for example, a vice or a clamp that fixes the material 70.

[0034] The control panel 7 controls a series of operations of the machine tool 1, from taking out the material 70 from the stocker 50, machining it, and storing the finished product 71 in the stocker 60. Although not shown, the control panel 7 is composed of hardware including a CPU that performs various calculations, a storage device such as a ROM or HDD that stores programs for the CPU to execute the calculations, a RAM that serves as a work area when the CPU executes the programs, and a communication interface that is an interface for sending and receiving data to and from other devices, and software that is stored in the storage device and executed by the CPU. For example, the control panel 7 includes a numerical control device. Each function of the control panel 7 is realized by the CPU loading various programs stored in the storage device into the RAM and executing them.

[0035] (Workpiece processing method) Next, a description will be given of a method for machining (processing) the blank 70. Fig. 6 is a flowchart of the method for machining the workpiece (blank 70) in embodiment 1. Note that in embodiment 1, the case where a jig 90 is used will be described as an example.

[0036] As shown in FIG. 6, a robot or an operator stacks and places a plurality of materials 70 in the stocker 50 in advance (S1). In response to a command from the control panel 7, the turntable 40 turns 180 degrees, and the first area 40a where the stockers 50 and 60 are placed is indexed into the machining chamber 15 (S2). The automatic tool changer 24 attaches the attachment tool 26 to the spindle 22 (S3). In response to a command from the control panel 7, the extrusion device 80 extrudes the materials 70 into the material storage area 48 (S4). The spindle 22 moves to the material storage area 48, and the attachment tool 26 holds the materials 70 extruded into the material storage area 48 (S5). In response to a command from the control panel 7, the turntable 40 turns 180 degrees, and the second area 40b where the jig 90 is placed is indexed into the machining chamber 15 (S6). The spindle 22 moves to the jig 90, and places the material 70 held by the attachment / detachment tool 26 on the jig 90 (S7). The automatic tool changer 24 attaches the tool 25 to the spindle 22, and processes the material 70 (S9). When processing is completed, the automatic tool changer 24 attaches the attachment / detachment tool 26 to the spindle 22 (S10). The spindle 22 moves to the jig 90, and the attachment / detachment tool 26 removes the product 71 from the jig 90 and holds it (S11). In response to a command from the control panel 7, the swivel table 40 rotates 180 degrees, and the first region 40a is indexed into the machining chamber 15 (S12). The spindle 22 moves to the stocker 60, and the product 71 held by the attachment / detachment tool 26 is released, and the product 71 is stored in the stocker 60 (S13).

[0037] The machine tool 1 according to the first embodiment provides the following advantageous effects.

[0038] The spindle 22 equipped with the attachment tool 26 can directly take out the blank 70 from the stocker 50 installed on the swivel table 40 and install it in the jig 90. Also, the spindle 22 equipped with the attachment tool 26 can directly remove the product 71 from the jig 90 and store it in the stocker 60 installed on the swivel table 40. Since the stockers 50 and 60 are provided in the first area 40a of the swivel table 40 in this way, if a robot or an operator previously installs a plurality of blanks 70 in the stocker 50, the machine tool 1 can automatically process the blanks 70 and store the product 71 in the stocker 60 until the plurality of blanks 70 are used up. Therefore, the machine tool 1 according to the first embodiment can realize labor saving and is suitable for small-lot production of a wide variety of products. Also, since the stockers 50 and 60 are provided on the swivel table 40, a transport robot or the like for transporting the blanks 70 and the product 71 is not required. Therefore, the entire system of the machine tool 1 can be made smaller and the installation area can be reduced.

[0039] In addition, since the machine tool 1 has the stockers 50, 60 built in, there is no need to provide additional space for installing the stockers around the machine tool 1. Furthermore, since the blank 70 is positioned at a predetermined position by the blank storage area 48, the attachment / detachment tool 26 can hold the blank 70 and correctly install it in the jig 90. Therefore, the machining precision of the product 71 is high.

[0040] The materials 70 are usually coated with anti-rust oil or the like, and when stacked in the stocker 50, the materials 70 may stick together. However, the extrusion device 80 can extrude (cut out) the stacked materials 70 one by one, so that the materials 70 can be accurately processed one by one.

[0041] Furthermore, since the position of the raw material 70 in the stocker 50 is restricted by the side walls 51, 52 and the partition 53 of the stocker 50, the raw material 70 does not shift within the stocker 50 when the swivel table 40 turns. Similarly, since the position of the product 71 in the stocker 60 is restricted by the support 61 and the partition 62 of the stocker 60, the product 71 does not shift within the stocker 60 when the swivel table 40 turns.

[0042] (Embodiment 2) Next, a second embodiment of the present invention will be described. Fig. 7 is a perspective view of a swivel table 140 of the second embodiment. As shown in Fig. 7, the swivel table 140 of the second embodiment is different from the first embodiment in that the configurations of the stockers 150, 160 are different and that the swivel table 140 of the second embodiment is provided with a posture changing device 100. The following description will focus on these differences, and the same reference numerals will be used to denote configurations that overlap with the first embodiment, and description thereof will be omitted.

[0043] The stocker 150 is provided on the support base 45, and stores block-shaped materials 170 by stacking them between the side walls 151 and 152. The side walls 152 slide on the rails 154 via the brackets 157. The fasteners 155 are, for example, bolts, and are inserted into the elongated holes 154a to fix the brackets 157 to the rails 154. In this way, the side walls 152 are positioned at any position on the rails 154. A gap 156 that is slightly larger than the height of the material 170 is provided between the lower parts of the side walls 151 and 152 and the support base 45. The material 170 is pushed out of the gap 156 by the push-out device 80, and while being guided by a pair of partition members 86, it collides with the stopper 85 and is placed in the material storage area 148. In the second embodiment, the plate thickness of the push-out plate 81 may be larger than that of the first embodiment.

[0044] The stocker 160 is provided on the support base 46, and stores block-shaped products 171 by stacking them between a pair of side walls 161. Fig. 8 is a diagram showing the internal configuration of the stocker 160 of the second embodiment, and Fig. 9 is a side view of the stocker 160 of the second embodiment. As shown in Figs. 8 and 9, the bottom 163 of the stocker 160 is formed with a plurality of steps 164 in a staircase shape. The height H1 of each step 164 is smaller than the height H2 of the product 171, and is, for example, about half the height H2.

[0045] The position-changing device 100 is installed in the first area 40a via a support base 45. The position-changing device 100 changes (tilts) the position of the material 170 or the semi-finished product 172. FIG. 10 is a perspective view of the position-changing device 100 of the second embodiment. As shown in FIG. 10, the position-changing device 100 includes a rectangular flat-plate-shaped seesaw member 101. The seesaw member 101 has a pair of support shafts 104. The support shafts 104 are, for example, cylindrical protrusions. The pair of support shafts 104 are fitted into holes 106 provided in a pair of side plates 105, respectively. The seesaw member 101 tilts about the pair of support shafts 104. The seesaw member 101 has a placement portion 102 on one side of the support shafts 104, on which the material 170 or the semi-finished product 172 is placed. The seesaw member 101 has a pressing portion 103 on the other side of the support shafts 104, which receives a pressing force. Furthermore, the position changing device 100 is provided with stoppers 107 and 108 to prevent the material 170 or the semi-finished product 172 from falling off the support table 45 .

[0046] Next, the operation of the posture changing device 100 will be described. Figures 11 and 12 are explanatory diagrams of the operation of the posture changing device 100 of the second embodiment. The claw 127 of the attachment / detachment tool 26 grips the material 170 or the semi-finished product 172 and drops it onto the placement part 102 of the seesaw member 101 (arrow B in Figure 10). Then, as shown in Figure 11, the material 170 or the semi-finished product 172 slides on the placement part 102 and moves to the end of the seesaw member 101. When the tip of the attachment / detachment tool 26 is replaced from the claw 127 to the push rod 128, the main shaft 22 descends, and the push rod 128 pushes the pressing part 103 downward, the seesaw member 101 tilts around the support shaft 104. Then, the end of the seesaw member 101 raises the material 170 or the semi-finished product 172 in the direction of arrow D in Figure 12. In this way, the posture of the material 170 or the semi-finished product 172 is changed by 90 degrees.

[0047] (Workpiece processing method) Next, a method for processing the raw material 170 according to the second embodiment will be described. The second embodiment is characterized in that a process of changing the posture of the semi-finished product 172 and finishing the product 171 is added between S9 and S10 in Fig. 6. Fig. 13 is a flowchart of the method for processing the semi-finished product 172 according to the second embodiment. Hereinafter, the procedure for changing the posture and processing the semi-finished product 172 will be described with reference to the process shown in Fig. 13. First, the raw material 170 goes through the processes S1 to S9 in Fig. 6 to complete the semi-finished product 172. The semi-finished product 172 goes through the processes S9-1 to S9-10 in Fig. 13 to finally become the product 171.

[0048] As shown in Fig. 13, the spindle 22 mounts the attachment tool 26 (S9-1). The spindle 22 moves to the jig 90, and the attachment tool 26 holds the semi-finished product 172 and removes it from the jig 90 (S9-2). In response to a command from the control panel 7, the swivel table 140 rotates 180 degrees and indexes the first area 40a in which the position change device 100 is installed into the machining chamber 15 (S9-3). The spindle 22 moves to the position change device 100, and the attachment tool 26 places the semi-finished product 172 on the position change device 100 (S9-4). Specifically, the attachment tool 26 drops the semi-finished product 172 onto the placement portion 102 of the seesaw member 101 (see Figs. 10 and 11). The position change device 100 changes the orientation of the semi-finished product 172 (S9-5). Specifically, the main shaft 22 grips the push rod 128 and pushes the pressing portion 103 of the seesaw member 101, causing the seesaw member 101 to stand up the semi-finished product 172 (see FIG. 12).

[0049] The spindle 22 moves to the posture changing device 100, and the attachment / detachment tool 26 holds the erected semi-finished product 172 (S9-6). In response to a command from the control panel 7, the swivel table 140 rotates 180 degrees, and the second region 40b in which the jig 91 is placed is indexed into the machining chamber 15 (S9-7). The spindle 22 moves to the jig 91, and the semi-finished product 172 held by the attachment / detachment tool 26 is placed on the jig 91 (S9-8). The automatic tool changer 24 attaches the tool 25 to the spindle 22 (S9-9), and the semi-finished product 172 is machined (S9-10). When machining is completed, the process proceeds to step S10 in FIG. 6, and the finished product 171 is finally stacked in the stocker 160.

[0050] The machine tool 200 according to the second embodiment provides the same operational effects as those of the first embodiment. In other words, it is possible to provide a machine tool 200 that can realize labor saving and is suitable for high-mix low-volume production. Furthermore, the second embodiment provides the following unique operational effects.

[0051] The spindle 22 equipped with the attachment / detachment tool 26 removes the semi-finished product 172 from the jig 90, and the posture changing device 100 changes the posture of the semi-finished product 172. The spindle 22 then places the semi-finished product 172 in the jig 91, and processes the semi-finished product 172 to complete the product 171. In this way, in the second embodiment, since the posture of the material 170 can be changed and it can be processed, a complex product 171 can be manufactured.

[0052] Since the stocker 160 sandwiches the product 171 between a pair of side walls 161, the front-rear (Y) direction of the product 171 is restricted.

[0053] In addition, since the step 164 is provided on the bottom 163 of the stocker 160, the products 171 can be stored side by side without any gaps. A specific description will be given with reference to Figs. 8 and 9. When the product 171a is placed on the bottom 163 and then the product 171b is placed next to the product 171a, if there is no step 164, the claw 127 interferes with the product 171a, so it is necessary to secure a space between the products 171a and 171b for the claw 127 to enter. However, if the step 164 is provided on the bottom 163 of the stocker 160 as in the second embodiment, the claw 127 does not interfere with the product 171a even if the claw 127 grabs the product 171b and places it next to the product 171a. Therefore, the product 171b can be placed next to the product 171a without any gaps.

[0054] Furthermore, when the products 171 are arranged on the step 164, the products 171 are restricted to each other in the left-right direction (X-axis direction). Therefore, the positions of the adjacent products 171 are restricted, and the positions do not shift when the swivel table 140 swivels.

[0055] The present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the gist of the present invention, and all technical matters included in the technical ideas described in the claims are the subject of the present invention. The above-described embodiment shows a preferred example, but a person skilled in the art can realize various alternatives, modifications, variations, or improvements from the contents disclosed in this specification, and these are included in the technical scope described in the attached claims.
