Description

The present invention relates to an industrial machine, a workpiece processing method, and a rotating table device.

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

With the above-mentioned 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. As a result, conventional machine tools improve the production volume per unit time of products, making them suitable for mass production of a small variety of products.

However, the above-mentioned conventional machine tools do not allow for labor savings because an operator must always be working in the transfer room. Furthermore, when machining a wide variety of workpieces in small quantities, the above-mentioned conventional machine tools require the operator to stop the machine tool and replace it with a new jig every time the type of workpiece changes. As a result, the production volume per unit time is low considering the amount of labor required by the operator. Therefore, the above-mentioned conventional machine tools are not suitable for high-mix low-volume production.

The present invention was made in consideration of the above-mentioned circumstances, and its purpose is to provide a new industrial machine, workpiece processing method, and rotating table device that can reduce the labor required and is suitable for high-mix low-volume production.

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 rotatable 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 installed; and a second area in which a jig for holding the workpiece is installed, and at least the bottom of the second stocker out of the first stocker and 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. This is an industrial machine.

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

A second aspect of the present invention is a method for processing a workpiece using an industrial machine as defined in any one of claims 1 to 7 , comprising: a first step of placing the workpiece before processing in the first stocker; a second step of indexing the first area of the swivel table to the first chamber and holding the workpiece before processing with the attachment/detachment tool; a third step of indexing the second area of the swivel table to the first chamber and placing the workpiece held in the second step in the jig; a fourth step of processing the workpiece placed in the jig with the work tool; a fifth step of holding the workpiece after processing with the attachment/detachment tool; and a sixth step of indexing the first area of the swivel table to the first chamber and storing the workpiece after processing held by the attachment/detachment tool in the second stocker.

Moreover, a third aspect of the present invention is a swivel table device comprising a swivel table and a rotation mechanism that rotates the swivel table around a swivel axis, the swivel 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 , and of the first stocker and the second stocker, at least the bottom of the second stocker is formed in a staircase-like shape with a plurality of steps, the height of each of the steps is lower than the height of the workpieces, and when the processed workpieces are arranged on the steps, the processed works are placed so as to regulate each other .

The present invention reduces the number of workers required and is suitable for small-lot production of a wide variety of products. Problems, configurations, and effects other than those described above will be clarified by the following embodiments.

(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 rotating table 40 of embodiment 1, and Fig. 3 is a plan view of the rotating table 40 of embodiment 1. In this specification, a workpiece before machining (before processing) is defined as a "material", a workpiece after processing (after processing) is defined as a "product", and a workpiece in the middle of machining (in the middle of processing) is defined as a "semi-finished product", and these terms are used.

As shown in FIG. 1 , machine tool 1 includes a machining chamber (first chamber) 15, a stocker chamber (second chamber) 10, a shutter 13, a rotation mechanism 30, a turning table 40, a stocker (first stocker) 50 , a 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.

The machine tool 1 is a vertical machine tool. Of course, as described above, the present invention can be applied to any industrial machine, such as horizontal machine tools, machining centers, grinding machines, hobbing machines, and other machine tools, as well as cleaning machines and deburring devices.

The spindle head moving device 23 allows the spindle head 21 to move freely in the left-right direction (X-axis), the front-back direction (Y-axis), and the up-down direction (Z-axis). The spindle 22 is supported by 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 mill, an end mill, a drill, or a tap.

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). The attachment/detachment tool 26 can be, for example, a device disclosed in Japanese Patent No. 6499063.

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 around 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.

As shown in Figures 2 and 3, the rotating table 40 has two areas 40a and 40b and a movable wall 42. The movable wall 42 divides the rotating table 40 into a first area 40a and a second area 40b.

The first area 40a and the second area 40b are arranged with 180-degree rotational symmetry around the rotation axis 41. By rotating the rotating 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 storage chamber 10.

The movable wall 42 is a flat plate. The movable wall 42 is fixed to the turntable 40 on a plane that includes the turning shaft 41 and is perpendicular to the turntable 40. The movable wall 42 turns integrally with the turntable 40 around the turning shaft 41. When the turntable 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.

The rotation mechanism 30 rotates the rotating table 40 around the rotation axis 41. The rotation mechanism 30 includes a motor as a drive source, a reducer, etc.

Stocker 50 stores raw material 70. Stocker 60 stores product 71. That is, in embodiment 1, raw material 70 and product 71 are stored separately. Raw material 70 and product 71 are, for example, rectangular flat plates. Raw material 70 and product 71 may also be, for example, disk-shaped or block-shaped.

The stocker 50 is placed in the first area 40a of the rotating table 40 via a support base 45.

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 a long 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 long hole 54a of the rail 54 to fasten the rail 54 and the bracket 57, and 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, and multiple materials 70 can be stacked and stored between the side walls 51 and 52. The partition 53 is integrally formed on the side walls 51 and 52, and prevents the material 70 from falling or keeps adjacent materials 70 spaced apart.

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, but smaller than twice the plate thickness t (t < gap 56 < 2t). In other words, the gap 56 is large enough to allow one sheet of material 70 to pass through.

The stocker 60 is placed in the second area 40b of the rotating table 40 via a support base 46.

The stocker 60 comprises a number 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 by stacking them between the support columns 61. The partition section 62 is integrally provided with the support columns 61, and prevents the products 71 from falling or keeps adjacent products 71 spaced apart.

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

The extrusion device 80 includes an extrusion plate 81 and a fluid cylinder 83. The thickness of the extrusion plate 81 is sufficient if 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 positioned to face the gap 56. The fluid cylinder 83 is provided on the back side of the support base 45 and reciprocates the rod 84 with 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 the 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.

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

The material storage area 48 is an area defined by the stopper 85, the partition member (protrusion) 86, and the rail 54 on the surface of the support table 45. The material storage area 48 is formed to have approximately the same external shape as the material 70. In other words, 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 rail 54, and is placed in the correct position without falling from the material storage area 48.

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

The jigs 90 and 91 are arranged in the second region 40b of the rotating table 40. The jigs 90 and 91 can each hold a different type of material 70. The jigs 90 and 91 can be configured in a suitable manner depending on the shape of the material 70, etc. The jigs 90 and 91 are, for example, a vice or clamp that fixes the material 70.

The control panel 7 controls a series of operations of the machine tool 1, from removing 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 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.

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

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 rotates 180 degrees, and the first area 40a where the stockers 50 and 60 are installed 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 rotates 180 degrees, and the second area 40b where the jig 90 is installed 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 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 tool 26 to the spindle 22 (S10). The spindle 22 moves to the jig 90 and the attachment 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 rotating table 40 rotates 180 degrees and indexes the first region 40a into the processing chamber 15 (S12). The spindle 22 moves to the stocker 60, releases the product 71 held by the attachment tool 26, and stores the product 71 in the stocker 60 (S13).

The machine tool 1 according to the first embodiment provides the following effects:

The spindle 22 equipped with the attachment tool 26 can directly take out the material 70 from the stocker 50 installed on the turntable 40 and install it in the jig 90. Also, the spindle 22 equipped with the attachment tool 26 can remove the product 71 from the jig 90 and directly store it in the stocker 60 installed on the turntable 40. In this way, since the stockers 50 and 60 are provided in the first area 40a of the turntable 40, if a robot or an operator installs a plurality of materials 70 in the stocker 50 in advance, the machine tool 1 can automatically process the material 70 and store the product 71 in the stocker 60 until the plurality of materials 70 are used up. Therefore, according to the machine tool 1 according to the first embodiment, labor saving can be realized and it is suitable for small-lot production of a wide variety of products. Also, since the stockers 50 and 60 are configured to be provided on the turntable 40, a transport robot or the like for transporting the material 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.

In addition, since the machine tool 1 has the stockers 50 and 60 built in, there is no need to provide additional space around the machine tool 1 to install the stockers. In addition, the material 70 is positioned in a predetermined position by the material storage area 48, so the attachment/detachment tool 26 can hold the material 70 and correctly install it in the jig 90. This results in high machining precision for the product 71.

The materials 70 are usually coated with anti-rust oil, etc., 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 the materials 70 can be precisely processed one by one.

In addition, the side walls 51, 52 and the partition 53 of the stocker 50 regulate the position of the material 70 in the stocker 50, so the material 70 does not shift within the stocker 50 when the swivel table 40 rotates. Similarly, the support pillars 61 and the partition 62 of the stocker 60 regulate the position of the product 71 in the stocker 60, so the product 71 does not shift within the stocker 60 when the swivel table 40 rotates.

(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 configuration of the stockers 150, 160 is 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.

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 fixing devices 155 are, for example, bolts, which 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.

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, approximately half the height H2.

The posture changing device 100 is installed in the first area 40a via the support base 45. The posture changing device 100 changes (tilts) the posture of the material 170 or the semi-finished product 172. FIG. 10 is a perspective view of the posture changing device 100 of the second embodiment. As shown in FIG. 10, the posture changing device 100 includes a rectangular flat 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 respectively fitted into holes 106 provided in a pair of side plates 105. 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 posture changing device 100 is equipped with stoppers 107 and 108 to prevent the material 170 or semi-finished product 172 from falling off the support table 45.

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 embodiment 2. The claw 127 of the attachment/detachment tool 26 grabs the material 170 or 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 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 semi-finished product 172 in the direction of arrow D in Figure 12. In this way, the posture of the material 170 or semi-finished product 172 is changed by 90 degrees.

(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 for 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. The procedure for changing the posture and processing the semi-finished product 172 will be described below 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.

As shown in FIG. 13, the spindle 22 attaches the attachment tool 26 (S9-1). The spindle 22 moves to the jig 90, where 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, where 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 part 103 of the seesaw member 101, causing the seesaw member 101 to stand up the semi-finished product 172 (see Figure 12).

The spindle 22 moves to the position changing device 100, and the semi-finished product 172 is held by the attachment/detachment tool 26 (S9-6). In response to a command from the control panel 7, the swivel table 140 rotates 180 degrees, and the second area 40b in which the jig 91 is installed 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 complete, the process proceeds to step S10 in FIG. 6, and the product 171 is finally stacked in the stocker 160.

The machine tool 200 according to the second embodiment provides the same effects as those of the first embodiment. In other words, it is possible to provide a machine tool 200 that can reduce manpower and is suitable for small-lot, multi-product production. Furthermore, the second embodiment provides the following unique effects:

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, the posture of the material 170 can be changed during processing, making it possible to manufacture a complex product 171.

The stocker 160 sandwiches the product 171 between a pair of side walls 161, restricting the front-to-back (Y) direction of the product 171.

In addition, because the bottom 163 of the stocker 160 is provided with a step 164, the products 171 can be stored side by side with no 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 will interfere with the product 171a, and it is necessary to secure a space between the products 171a and 171b for the claw 127 to enter. However, if the bottom 163 of the stocker 160 is provided with a step 164 as in embodiment 2, the claw 127 will not interfere with the product 171a even if it 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.

Furthermore, when the products 171 are arranged on the step 164, the products 171 are regulated relative to each other in the left-right direction (X-axis direction). Therefore, the positions of adjacent products 171 are regulated, and the positions do not shift when the rotating table 140 rotates.
