  The transfer device of the first conventional example transfers workpieces between adjacent production machines, whereas the transfer device of the second conventional example can transfer workpieces between a plurality of machine tools. Thus, it is comprised so that a workpiece | work may be conveyed in a wide range. However, in a processing machine line where the number of production machines is large and a plurality of transfer robots are mounted, it is necessary to transfer workpieces between the transfer robots. However, at this time, since it is necessary to match the movements of the transfer robots, it takes much time and productivity is lowered. Even if the transfer robot is provided with a work stand as in the second conventional example, one transfer robot must go to the other transfer robot to pick up the work. It will decrease. For example, by providing a temporary placement space for workpieces in the processing machine line, a plurality of transfer robots can move independently. However, this takes up space only for temporary placement of workpieces, which increases the size of the entire processing machine line.

  Accordingly, an object of the present invention is to provide a multi-function work table module capable of placing various works in a small space in order to solve such a problem.

The multifunctional work table module in one aspect of the present invention includes a temporary table for temporarily placing a work, and an inappropriate work table for storing a plurality of work pieces determined to be inappropriate in the front-rear direction of the machine body. The temporary placement table and the inappropriate work table are arranged above and below, and a plurality of work modules for performing a predetermined work are arranged in the width direction on the base arranged in the width direction together with the work modules. Is possible .

  According to the present invention, by temporarily placing a work on the temporary placing table of the multi-function work placing table module, it is possible to extract a work for delivery and quality check between a plurality of transfer robots. It is also possible to store a plurality of inappropriate workpieces determined to be inappropriate on the appropriate workpiece table. In addition, the multifunctional work table module can be installed in a small space because the temporary table and the inappropriate work table are arranged vertically.

  Next, an embodiment of a multifunction work table module according to the present invention will be described below with reference to the drawings. FIG. 1 is a front view showing a processing machine line provided with the multi-function workpiece mounting module of the present embodiment. This processing machine line 100 includes various modules such as a lathe, a machining center, or a measuring machine between a workpiece loading module 1 at the right end of the drawing as a workpiece carry-in portion and a workpiece discharge module 11 at the left end of the drawing as a workpiece carry-out portion. It was installed side by side. The workpiece sent from the workpiece input module 1 is conveyed to the workpiece discharge module 11 on the left side of the drawing through processes in various modules, such as cutting with a module such as a lathe.

  Specifically, lathe modules 2 and 3 are installed next to the workpiece input module 1, and the inspection module 4 is installed next to it. Accordingly, after the workpiece is subjected to the first machining and the second machining in the lathe modules 2 and 3, the inspection module 4 checks the dimensional accuracy of the workpiece after machining. Next to the inspection module 4, a multi-function work table module (hereinafter simply referred to as “work table module”) 5 of the present embodiment is installed. The workpiece placing module 5 stores temporary workpieces for workpiece delivery and quality check, and stores inappropriate workpieces determined to be inappropriate in the inspection process. Further, the work table module 5 is configured such that a work can be taken out by an operator.

  A machining center module 6 that performs boring, drilling, and the like is installed next to the work table module 5 to perform third processing on the work. Next, a second work table module 7 is installed next to the machining center module 6. In the work table module 7, temporary work placement and work removal for quality check are performed.

  Further, a hobbing machine module 8 for performing gear cutting is installed next to the work placing module 7 so that the fourth processing for the work is performed. Next to that, a deburring module 9 for removing burrs generated on the workpiece by processing and a cleaning module 10 for washing off chips and the like attached to the workpiece are installed in order, and further, a workpiece discharging module is next to it. 11 is installed. The processing machine line 100 is composed of such a plurality of modules 1 to 11, and a predetermined processing or the like is performed while the workpiece moves between the modules 1 to 11. Accordingly, the processing machine line 100 is provided with a workpiece transfer device for moving workpieces in order.

  The work transfer device is configured by a transfer work machine 15 (15A, 15B) in which an articulated robot arm 152 is turnably mounted on a traveling table 151 that moves on a traveling rail provided in front of each module 1-11. It is configured. Two processing machines 15A and 15B are mounted on the processing machine line 100, and each of them moves independently on the same traveling rail, and workpieces are transferred to and from each module. The processing machine line 100 is entirely covered with an exterior cover 18, and an opening / closing cover 180 is provided at the front. The opening / closing cover 180 constitutes one transfer space 800 (see FIG. 3) that extends in the width direction in which the transfer work machine 15 moves. A processing space for sealing the processing parts of the modules 1 to 11 and the like are formed at the rear of the conveyance space 800.

  Here, one of the machine tools constituting the processing machine line 100 will be described for reference. FIG. 2 is a perspective view showing the main structure of the machining center module 6. The machining center module 6 is mounted on the base 16 so as to be movable in the front-rear direction (Y-axis direction). In the base 16, two rails 160 are laid at the same width interval so that two modules can be mounted. In the processing machine line 100, five bases 16 are arranged side by side in close proximity to the modules 2 to 10, and are mounted on the modules 16 so as to be movable in the front-rear direction similarly to the machining center module 6.

  Only the hobbing module 8 has a width corresponding to the entire base 16, but the other modules 2 to 7, 9, and 10 are unified with a width that is approximately half the width of the base 16. The processing machine line 100 has a uniform appearance with respect to all the modules 1 to 11 and has not only the width dimension but also the outer shape. Such a processing machine line 100 is designed to be very compact as a whole by adopting a configuration in which a plurality of modules 1 to 11 have a reduced width dimension and are arranged close to each other in the width direction. Therefore, the machining center module 6 shown in FIG. 2 has a compact configuration.

  The machining center module 6 is assembled on a movable bed 604 that matches the rail width of the two rails 160. In the movable bed 604, a spindle head 601 including a spindle chuck 611 and a spindle motor 612 that can be attached and detached with a tool is disposed in the front part. A chuck device 602 is provided below the spindle head 601 for gripping the workpiece rotatably. A tool magazine 603 storing a plurality of tools is provided between the spindle head 601 and the chuck device 602 so that the tool can be changed with respect to the spindle chuck 611 according to the processing content.

  The spindle head 601 is movable according to the three-dimensional coordinates of the X axis, the Y axis, and the Z axis, and a drive mechanism for that is arranged in the longitudinal direction of the machine body (Y axis direction). That is, the Y-axis slider 605, the X-axis slider 606, and the Z-axis slider 607 are assembled at positions where they overlap each other in the Y-axis direction, and the dimension in the width direction that is the X-axis direction is reduced. Each of the sliders 605, 606, and 607 is controlled by a ball screw mechanism so that the rotation output of each servo motor is converted into a linear motion, and the movement in each direction can be controlled. A control panel 608 that performs the drive control is mounted on the rear portion in the Y-axis direction.

  The base 16 that is the same as the machining center module 6 is mounted with a work stage module 7 on the side of the subsequent process, and the work stage module 7 is also configured to be movable in the front-rear direction on the rail 160. On the other hand, the work table module 5 on the front process side is mounted on the same base 16 as the inspection module 4, and is also configured to be movable in the front-rear direction. Although the two work table modules 5 and 7 are configured in the same manner, in the present embodiment, the work table module 5 on the pre-process side used for more applications will be described. FIG. 3 is a perspective view showing the internal structure of the work table module 5.

  The work table module 5 serves as a relay point for the transfer work machines 15A and 15B to transfer the work, and receives the work 200 of the transfer work machine 15B shown in FIG. 4 and the work 200 by the transfer work machine 15A. Is being sent in. Further, as shown in FIG. 3, the workpiece 200 extracted for quality check may be temporarily placed at the same position. In addition, the work 200 may be determined to be inappropriate by inspection, and in such a case, as shown in FIG. In the work table module 5, a temporary table 21 and an inappropriate work table 22 are assembled in two upper and lower stages so as to correspond to such applications.

  The work table module 5 includes a movable bed 23 movable on a rail 160 and a frame body 25 including a pillar member 26 (front pillar 261, rear pillar 262), a frame member 27, and the like. ing. Both the temporary placement table 21 and the inappropriate work table 22 are assembled with a structure that can move in the front-rear direction with respect to the module body 25. Here, FIG. 6 is a side view showing the assembly position of the temporary placing table 21 and the inappropriate work table 22, and in particular, the temporary placing table 21 is in the forward position and the inappropriate work table 22 is in the retracted position. The case is shown.

  In the temporary placement table 21, a work table 32 on which a work 200 is placed is formed on the upper surface of the front portion of a rectangular slide table 31, and a guide rail 33 is fixed to the lower surface of the slide table 31. The guide rail 33 is slidably fitted to a guide block 34 fixed to the movable bed 23 side. An air cylinder 35 is fixed to the upper surface of the slide table 31, and a piston rod 351 protruding rearward is connected to a support member 36 fixed to the movable bed 23. Accordingly, the slide table 31 (temporary placing table 21) moves to the retracted position on the movable bed 23 shown in FIGS. 3 and 5 by the contraction operation of the air cylinder 35, and FIGS. 4 and 6 by the extension operation of the air cylinder 35. Will move to the forward position shown in FIG.

  An inappropriate work table 22 is assembled above the temporary table 21. The inappropriate work table 22 has a plurality of conveying rollers 42 attached to the frame 41 side by side in the front-rear direction. The frame 41 has a pair of frames 412 fixed to the left and right long sides of a rectangular bottom plate 411, and a plurality of transport rollers 42 are rotatably attached to the left and right frames 412. An arm 413 is fixed to one frame 412 so as to protrude forward. The arm 413 has a handle 415 formed at the tip thereof, and the operator can pull out the inappropriate work table 22 forward by pulling the handle 415. Further, a hook 43 is detachably attached to the arm 413 so that the inappropriate work 300 located behind the inappropriate work table 22 can be pulled out.

  By the way, the posture of the unsuitable work table 22 is changed as it moves back and forth so that it is in a backward tilted position at the retracted position shown in FIG. It is configured to A rail plate 44 is fixed between the front column 261 and the rear column 262, and a guide rail 45 is fixed thereto. The rail plates 44 are provided on both the left and right sides in the width direction, and the guide rails 45 provided on both are symmetrically arranged on the inner side. The guide rail 45 formed in a straight line is divided into a horizontal front portion 453, a middle portion 452 having a large slope, and a rear portion 451 having a small slope.

A support plate 46 that is orthogonal to the bottom plate 411 is fixed to the rear end portion of the base frame 41, and cam followers 47 are attached to the upper end portion of the inappropriate work base 22 via brackets on both sides in the left and right width directions. . A pair of left and right cam followers 47 are mounted on the guide rail 45 in a rotatable state. Therefore, the rear end portion of the inappropriate work table 22 is suspended by the support plate 46. The support plate 46 also supports the improper workpiece 300 because the improper workpiece 300 slides backward when the improper workpiece table 22 is tilted backward.

  On the other hand, a support roller 48 is stretched over the left and right front pillars 261, and an inappropriate work table 22 is placed thereon. Further, a support bar 49 provided with wheels is fixed downward on the front part of the inappropriate work table 22, and the wheels roll on the slide table 31 during the movement. The front part of can be supported. Therefore, when the inappropriate work table 22 moves back and forth, the height of the support roller 48 is constant, and the cam follower 47 on the rear side is displaced up and down, so that the posture of the inappropriate work table 22 is inclined backward and horizontal. It has come to change between.

  As shown in FIG. 5, the inappropriate work table 22 in the retracted position is fed with the inappropriate work 300 introduced from the front on the plurality of transport rollers 42 to the rear side. At that time, a pair of left and right guides 52 are attached to the inappropriate work table 22 so as to be stored in a line. The guide 52 is a belt-like plate and is connected to the frame 412 via an L-shaped bracket 51. A long hole is formed in the bracket 51 and is fastened to the frame 412 and the guide 52 by a bolt that passes through the long hole. Therefore, by adjusting the position of the bolt with respect to the elongated hole, the height and interval of the guide 52 can be adjusted according to the size of the inappropriate work 300.

  By the way, when an operator takes out a workpiece | work from the workpiece mounting module 5, the front part of the temporary mounting table 21 and the inappropriate work table 22 which moved to the advance position is located in the taking-out space 850 as shown in FIG. The take-out space 850 is created in the open / close cover 180 protruding from the front portion of the exterior cover 18 shown in FIG. The open / close cover 180 is configured in the same manner in all the modules 1 to 11 of the processing machine line 100, and as shown in FIGS. 4 and 5, the transfer work machine 15 is moved in the front portion of the base 16. A conveyance space 800 for working is created. Accordingly, since the take-out space 850 is located in the transfer space 800, it is necessary to prevent the transfer work machine 15 from entering during the take-out operation performed by the worker.

  Therefore, in the present embodiment, there is a safety device for preventing the transfer work machine 15 from entering the take-out space 850 in front of the work placing modules 5 and 7 even when the work transfer to another module is performed. Is provided. Here, FIG. 7 is a perspective view showing the work table module 5 in a state where the safety device is activated and the opening / closing cover 180 is opened. In this figure, the safety cover 60 constituting the safety device is seen through so that the relationship between the components can be easily understood (the same applies to FIG. 3). FIG. 8 is a perspective view showing the work table module 5 from below.

  The safety cover 60 is integrally formed with an upper top plate 62 and a lower jaw member 63 so as to connect a pair of left and right protective plates 61. The pair of left and right protection plates 61 are formed in a shape that matches the opening / closing cover 180, and a take-out space 850 is created by dividing the transport space 800 at the forward position. On the other hand, in the retracted position shown in FIG. 3, the safety cover 60 returns to the movable bed 23 and opens the transfer space 800 so as not to hinder the movement of the transfer work machine 15. The pair of protective plates 61 are formed in accordance with the interval between the left and right column members 26, and the temporary placement table 21 and the inappropriate work table 22 are placed in the safety cover 60.

  The safety cover 60 that can be moved back and forth has a guide block fixed to the top plate 62, and the guide block is slidably fitted to two ceiling guide rails 67 fixed to the module body 25. . An air cylinder 68 similarly arranged in the front-rear direction is fixed to the module body 25 between the two ceiling guide rails 67 arranged in the front-rear direction, and the piston rod of the air cylinder 68 is attached to the safety cover 60. The top plate 62 is connected. Therefore, the safety cover 60 that can move back and forth along the ceiling guide rail 67 moves backward by the contraction operation of the air cylinder 68 and moves forward by the extension operation.

  The air cylinders 35 and 68 for moving the temporary placement table 21 and the safety cover 60 back and forth are connected to an air compressor installed at the back of the processing machine line 100. The air hose connecting the air cylinders 35 and 68 and the air compressor is connected to an air circuit having a fluid device such as a solenoid valve, and compressed air is supplied and exhausted according to energization control by a control panel 58 installed at the rear of the module. It is like that. The energization control to the solenoid valve or the like via the control panel 58 can be executed in accordance with an input from the operation panel 57 attached to the front surface portion of the outer cover 18 of the module. A plurality of operation panels 57 can select modules, and can be confirmed by input or display from any position.

  By the way, when the opening / closing cover 180 is opened as shown in FIG. 7, the safety cover 60 needs to be surely in the advanced position and create the extraction space 850. Therefore, in the present embodiment, the opening / closing cover 180 is configured to be opened in a state where it is confirmed that the safety cover 60 is in the forward movement position. Therefore, the open / close cover 180 is provided with an electromagnetic lock device, and the lock is released based on a signal from a detection sensor that detects the advance position of the safety cover 60.

  Next, the operation of the work table module 5 in the processing machine line 100 will be described. In the processing machine line 100, the workpiece set in the workpiece input module 1 is taken out by the conveyance work machine 15A and conveyed to each module in turn. After the workpiece is machined by the lathe modules 2 and 3, the machining dimension is measured by the inspection module 4, and what is determined to be appropriate is placed on the temporary platform 21 of the workpiece platform module 5. On the other hand, what is determined to be inappropriate as a result of measurement is placed on the inappropriate work table 22 as an inappropriate work 300 as shown in FIG.

  The appropriate workpiece 200 is placed on the work table 32 of the temporary table 21 for delivery from the transfer work machine 15A to the transfer work machine 15B. At the time of delivery, the temporary table 21 may be in the forward position as shown in FIG. 4 or in the backward position as shown in FIG. That is, the position of the temporary placing table 21 may be controlled so that the driving of the transfer work machines 15A and 15B is reduced so that the processing time can be shortened. On the other hand, the retracted position shown in FIG. When the improper workpiece 300 is put into the improper workpiece table 22 in the backward tilted posture, the improper workpiece 300 is sandwiched from both sides by the guide 52 and slides on the conveying roller 42 to move backward. In the present embodiment, a maximum of four inappropriate works 300 are stored, although it varies somewhat depending on the work size.

As shown in FIG. 4, the workpiece 200 placed on the temporary placement table 21 is gripped by the transfer work machine 15 </ b> B and transferred to the next machining center module 6. Thereafter, the workpiece is transferred to the hobbing module 8, the deburring module 9, and the cleaning module 10 beyond the workpiece table module 7, and finally sent to the workpiece discharge module 11. In the work table module 7, for example, the work 200 extracted at a ratio of one out of every tens is placed on the temporary table 21, and a quality check is performed by the operator. The quality check is performed in the same manner in the work table module 5.

  In the quality check of the workpiece 200, as shown in FIG. 7, the temporary placing table 21 moves to the forward movement position, and the target workpiece 200 is sent out to the take-out space 850. FIG. 7 shows a state in which the inappropriate work table 22 is also moved to the forward position. However, it is not necessary to take out the inappropriate work 300 in accordance with the quality check, and when the number reaches the number that can be stored. To do so. However, the description will be made on the assumption that the same timing is used. In the work removal operation, the temporary placement table 21 and the safety cover 60 are operated to move forward and backward by an input on the operation panel 57 by the operator.

  The temporary placing table 21 moves forward to the position shown in FIG. 7 so that the air cylinder 35 extends and is pushed out. At this time, the safety cover 60 is also moved forward by the extension operation of the air cylinder 68. That is, the movement of the safety cover 60 is performed by an operation for moving the temporary placement table 21. On the other hand, since the operator himself pulls out the inappropriate work table 22, the safety cover 60 must advance in advance to create the take-out space 850. Therefore, in the case of only taking out the unsuitable workpiece 300, the moving operation of only the safety cover 60 is performed.

  When the safety cover 60 reaches the forward movement position, the conveyance space 800 is divided by the pair of protection plates 61, and an extraction space 850 is created. At this time, the detection sensor detects that the safety cover 60 has reached the forward movement position, and the electromagnetic lock device of the opening / closing cover 180 is released by the control panel 58 that has received the detection signal. Therefore, the operator can open the opening / closing cover 180 by pulling it upward as shown in FIG. 7, and the front surface of the work table module 7 is opened. Then, the operator puts his hand into the take-out space 850, grasps the handle 415, and pulls out the inappropriate work table 22 forward. At this time, the rear end portion of the unsuitable work table 22 rises when the cam follower 47 rolls on the guide rail 45, so that the inappropriate work table 22 changes from the backward tilted posture to the horizontal posture.

  The operator takes out the quality check workpiece 200 from the temporary table 21 and takes out the inappropriate workpiece 300 from the inappropriate workpiece table 22, but the inappropriate workpiece 300 located at the rear is moved forward using the hook 43. It can be taken out by pulling it out. After the workpiece is taken out, the inappropriate work table 22 is moved to the retracted position so that the operator pushes it in. After the opening / closing cover 180 is closed and the closed state is detected, the temporary placement table 21 and the safety cover 60 are moved to the retracted position by the contraction operation of the air cylinders 35 and 68 by the input of the retract signal from the operation panel 57. Moving.

  Since the quality check of the workpiece 200 is performed at a rate of one for a certain number of workpieces as described above, the timing of the removal operation is displayed on the operation panel 57 by counting the number of workpieces. On the other hand, the number of improper workpieces 300 put on the improper workpiece table 22 is also counted and displayed on the operation panel 57 or the signal tower 59 is lit when it is confirmed that the number of mountable workpieces has been reached. The operator is informed that removal is necessary.

  By the way, the unloading work of the unsuitable workpiece 300 is limited in the movement of the transfer work machine 15 in the unloading space 850, and therefore, the drive of the adjacent module may have to be temporarily stopped during that time. However, this will increase the processing time and reduce the production efficiency. Therefore, it is desirable to continue the processing even when the inappropriate work 300 is taken out. FIG. 9 is a perspective view of the second embodiment showing the internal structure of the work table module 12 in consideration of such points. The same code | symbol is attached | subjected about the structure similar to the workpiece mounting base module 5 of the said 1st Embodiment.

  The work table module 12 is different from the inappropriate work table 24. That is, the inappropriate work table 24 is fixed without moving, and is configured to protrude rearward from an unillustrated exterior cover 18. The inappropriate work table 24 has the same structure as the inappropriate work table 22 of the above-described embodiment, and a plurality of transport rollers 72 are attached to the frame 71 side by side in the front-rear direction. In particular, the underframe 71 is long, and is fixed at a position where the height is different from that of the front pillar 261 and the rear pillar 262, and is in a rearward inclined posture as shown in the figure. A pair of belt-like guides 73 are attached to the underframe 71 so as to be adjustable in the vertical direction and the width direction, and a support plate 75 is fixed to the rear end portion.

  Accordingly, the improper workpiece 300 put on the improper workpiece platform 24 in the backward tilted posture is sandwiched from both sides by the guide 73 and is slid on the conveying roller 72 and sent backward. In the present embodiment, a maximum of 10 inappropriate works 300 are stored. The number of improper workpieces 300 is counted every time it is thrown in. When it is confirmed that the number of inappropriate workpieces has been reached, it is displayed on the operation panel 57 or taken out to the operator by turning on the signal tower 59. Is informed that it is necessary. The operator goes to the back side of the processing machine line 100 and takes out the inappropriate work 300 in order from the rear end of the inappropriate work table 24. Since the inappropriate work table 24 is inclined rearward, the inappropriate work 300 is recovered in the order of sliding backward.

  Therefore, according to the work placing table module 5 of the present embodiment, not only the delivery of the work 200 in the transfer work machines 15A and 15B but also temporary placement for quality check is possible, and further, the inappropriate work 300 is stored. Can also be used. The work table module 5 includes the temporary table 21 and the inappropriate work table 22 arranged in two upper and lower stages, so that the width dimension can be kept small, and is mounted on the base 16 like the other modules. can do. In particular, since the work table module 5 itself can be moved in the front-rear direction by being mounted on the rail 160 of the base 16, the processing machine line 100 can be easily changed in layout by replacing the modules.

  Since the temporary placing table 21 can be automatically moved back and forth by the air cylinder 35, when the workpiece 200 is transferred by the transfer work machines 15A and 15B, the temporary placing table 21 is set at an appropriate position between the forward position and the backward position in order to shorten the processing time. Can be moved. Further, at the position where the temporary placing table 21 is retracted into the module main body 25, the transfer work machines 15A and 15B can pass forward. Therefore, in some cases, the transfer work machines 15A and 15B can directly transfer the workpiece 200 to the machining center module 6 or the inspection module 4 beyond the workpiece table module 5 without using the temporary table 21. .

  Further, since the temporary placement table 21 and the inappropriate work table 22 are moved to the forward movement position and the work place is near the worker who opened the open / close cover 180, the work can be easily taken out. The inappropriate work table 22 is moved back and forth by the operator, but can be easily moved in the front-rear direction by being pulled out or pushed in via the arm 413 with the handle 415. Further, since the hooking rod 43 is provided, the inappropriate work 300 in the back can be easily pulled out. Further, since the inappropriate work table 22 is in a backward tilted position at the retracted position, the thrown inappropriate work 300 is naturally moved to the back and stored, and when it is moved to the advanced position, it is in a horizontal position. Easy to take out.

  When the operator opens the opening / closing cover 180, the safety cover 60 is surely moved to the transfer space 800 to create the take-out space 850, so that the work for taking out the workpieces 200, 300 by the worker is secured. The The inappropriate work table 22 in the advanced position is in a position where the handle 415 protrudes forward of the safety cover 60 as shown in FIG. Therefore, the handle 415 interferes even if the operator closes the open / close cover 180 by forgetting to return the inappropriate work table 22. Therefore, it is possible to prevent a collision with the transfer work machine 15 caused by forgetting to return the inappropriate work table 22.

  Further, in the work placing table module 12 of the second embodiment shown in FIG. 9, since the inappropriate work table 24 is long, a larger number of inappropriate work 300 can be stored, and the number of times the operator takes out the work. Can be reduced. In addition, since it is a rear discharge type that protrudes to the rear of the work table module 5, the inappropriate work 300 can be taken out without interrupting the processing by the processing machine line 100.

As mentioned above, although one Embodiment of this invention was described, this invention is not limited to these, A various change is possible in the range which does not deviate from the meaning.
For example, in the above-described embodiment, the temporary placing table 21 is disposed below and the inappropriate work table 22 is disposed above, but the upper and lower arrangements may be reversed.
In the above embodiment, the conveying space 800 is separated by the pair of protective plates 61 to create the take-out space 850. However, the configuration may not be in the form of the safety cover 60.

  Further, although the air cylinders 35 and 68 are used as actuators for driving the temporary placing table 21 and the safety cover 60, an electric cylinder or the like may be used. Furthermore, in the above-described embodiment, the temporary placing table 21 is automatically moved back and forth by the actuator. However, when performing a quality check, the operator manually moves the front and back like the inappropriate work table 22. Also good.
