The nonwoven fabric 724D passes through a variable roller 724F provided near the take-up roller 724B provided on the −X-axis direction side and three fixed rollers 724G provided on the +X-axis direction side of the variable roller 724F. The film is then wound up from the take-up roller 724B provided on the −X-axis direction side to the take-up roller 724B provided on the +X-axis direction side.

As shown in FIG. 18, the variable roller 724F includes a rod-shaped body 724F1 rotatably supported at one end by a base 724A, and a roller body 724F2 rotatably provided at the other end of the rod-shaped body 724F1. We are prepared. This variable roller 724F adjusts the tension of the nonwoven fabric 724D by adjusting the position of the rod-shaped body 724F1. Specifically, the variable roller 724F can increase the tension of the nonwoven fabric 724D by rotating the rod-shaped body 724F1 counterclockwise, and by rotating the rod-shaped body 724F1 to the position indicated by the solid line in the figure. , the tension of the nonwoven fabric 724D can be maximized. In addition, the variable roller 724F can reduce the tension of the nonwoven fabric 724D by rotating the rod-shaped body 724F1 clockwise, and by rotating the rod-shaped body 724F1 to the position indicated by the two-dot chain line in the figure, the tension of the nonwoven fabric 724D can be reduced. 724D tension can be minimized.

As shown in FIGS. 17 and 18, the friction cleaner 724E includes a sliding mechanism 724H that contacts the upper surface of the inner plate D via the nonwoven fabric 724D and rubs the upper surface of the inner plate D and the nonwoven fabric 724D, and a sliding mechanism 724H that rubs the upper surface of the inner plate D and the nonwoven fabric 724D. The sliding mechanism 724H is supported so as to be movable forward and backward along the support mechanism 724E1, which is fixed to the plate 724A3 of the base 724A. This support mechanism 724E1 can adjust the position of the sliding mechanism 724H with respect to the upper surface of the inner plate D by moving the sliding mechanism 724H forward and backward along the Z-axis direction.

The shaft 724H7 is fixed, and the other end is rotatably fixed to the end of the moving body 724H3 on the -Y axis direction side.

FIG. 20 is a diagram showing a state in which the upper surface of the inner tray and the nonwoven fabric are being rubbed together in a friction cleaning machine.
The central axis of one end of the shaft 724H7 fixed to the motor 724H5 is eccentric with respect to the output shaft of the motor 724H5. Therefore, when the output shaft of the motor 724H5 is rotated, one end of the shaft 724H7 rotates around the output shaft of the motor 724H5, as shown in FIG. 20 (see arrow in the figure). The shaft 724H7 moves back and forth along the guide rail 724H2 as the output shaft of the motor 724H5 rotates, and the contact plate 724H4 moves back and forth along the Y-axis direction via the shaft 724H7 and the moving body 724H3. I will do it. Therefore, the sliding mechanism 724H can bring the contact plate 724H4 into contact with the upper surface of the inner plate D via the nonwoven fabric 724D, and rub the upper surface of the inner plate D and the nonwoven fabric 724D.

After cleaning other surfaces different from the upper surface of the inner plate D, the upper surface of the inner plate D is finally cleaned, but the surface of the inner plate D may be cleaned in a different order from this.
The top surface deep cleaning mechanism 724 also includes a cloth cleaning tool (non-woven fabric 724D) that cleans the top surface of the inner tray D, and a sliding mechanism 724H that slides this cloth cleaning tool along the upper surface of the inner tray D. However, a different configuration may be adopted as long as the surface of the inner plate D can be thoroughly cleaned.

A motor 733 rotates the rollers 732, a belt 734 is wound around each roller 732, and a belt conveyor 735 conveys the inner plate D toward the -X axis direction.

The belt 734 includes a plurality of hooks 734A that are L-shaped in an XZ plan view and are spaced apart from each other by a predetermined distance on its outer peripheral surface. This belt 734 is configured to rotate intermittently in synchronization with the rotation of the first index 71 and the second index 72 by rotating a roller 732 fixed in the +Z-axis direction using a motor 733. .
Specifically, by rotating the disc part 721 of the second index 72, the arm part 722 holding the medium plate D by the chuck 722A is brought to rest at a position below the medium plate delivery mechanism 73, and then the motor 733 is rotated. , by rotating the belt 734, the hook 734A is moved to a position below the inner plate D. Thereafter, the second index 72 releases the inner plate D by retracting the claw portion of the chuck 722A relative to the inner plate D. As a result, the inner plate D is placed on the upper surface of the hook 734A of the belt 734. Then, the motor 733 moves the hook 734A on which the inner plate D is placed to a position above the belt conveyor 735 by rotating the belt 734.

The belt conveyor 735 has a conveyance path 735A on which the inner plate D is placed, and a convex portion 735B provided on the conveyance path 735A at a predetermined distance. By moving the conveyance path 735A toward the -X axis direction, the belt conveyor 735 pushes out the medium plate D placed on the upper surface of the hook 734A of the belt 734 with the convex portion 735B, and transfers it to the second index 72. The medium plate D that has been transported is transported toward the −X-axis direction.

The control means 74 includes an inner plate holding control section 741, an inner plate cleaning control section 742, and a transport control section 743.

The inner plate holding control unit 741 controls the holding and release of the inner plate D by controlling the forward and backward movement of the chuck 712A of the first index 71 and the forward and backward movement of the chuck 722A of the second index 72.
The inner plate cleaning control unit 742 cleans the surface of the inner plate D by controlling the bottom surface cleaning mechanism 713, the parallel side surface cleaning mechanism 714, the inclined side surface cleaning mechanism 723, and the top surface deep cleaning mechanism 724.

FIG. 26 is a flowchart showing a method of controlling the inner tray cleaning device.
When the inner plate cleaning device 7 cleans the surface of the inner plate D, the control means 74 executes steps ST1 to ST5 as shown in FIG. 26 according to a predetermined program stored in the memory.
First, the inner plate holding control unit 741 holds and releases the inner plate D (step ST1: inner plate holding/releasing step). Specifically, the middle plate holding control unit 741 causes the first index 71 to hold the middle plate D conveyed by the middle plate conveyor 70, as described above. Further, as described above, the inner plate holding control unit 741 causes the second index 72 to hold the inner plate D transported by the first index 71, and then causes the first index 71 to release the inner plate D. Furthermore, the inner plate holding control unit 741 causes the second index 72 to release the inner plate D, as described above.

In addition, the inner plate cleaning control unit 742 executes cleaning of the surface of the inner plate D (step ST2: inner plate cleaning step). Specifically, the inner plate cleaning control unit 742 causes the bottom surface cleaning mechanism 713 to clean the bottom surface of the inner plate D, as described above. Further, as described above, the inner plate cleaning control unit 742 causes the parallel side cleaning mechanism 714 to clean both side surfaces of the inner plate D that are parallel to each other.

Further, the inner plate cleaning control unit 742 causes the upper surface dense cleaning mechanism 724 to closely clean the upper surface of the inner plate D, as described above.
Note that the control means 74 executes step ST1 and step ST2 substantially simultaneously.

Next, the control means 74 determines whether or not holding and releasing the inner plate D has been completed (step ST3: inner plate holding/release determining step).
When it is determined in step ST3 that holding and releasing the inner plate D has been completed, the control means 74 determines whether cleaning of the inner plate D has been completed (step ST4: inner plate cleaning determination step). ).
If it is determined in step ST3 that holding and releasing the inner plate D has not been completed, and if it is determined in step ST4 that cleaning of the inner plate D has not been completed, the control means 74: The process of step ST3 is executed again.

In this embodiment, the control means 74 determines whether holding and releasing the inner plate D is completed in step ST3, and determines whether cleaning of the inner plate D is completed in step ST4. However, if it is determined that these processes have not been completed, the process in step ST3 is executed again without executing the next process. If it is determined that a predetermined time has elapsed, the next process may be executed.

When the conveyance control unit 743 determines that the cleaning of the inner plate D is completed in step ST4, the transport control unit 743 controls the rotation and elevation of the first index 71, the rotation and elevation of the second index 72, and the inner plate delivery mechanism 73. The middle plate D is conveyed by controlling the rotation of the belt 734 (step ST5: middle plate conveying step). After that, the control means 74 executes step ST1 again.

It functions as a cleaning control unit that causes the bottom cleaning mechanism 713 and the parallel side cleaning mechanism 714 to clean the held inner plate D.
Further, in this embodiment, the inner plate holding control unit 741 functions as a side holding control unit that causes the second index 72 to hold the inner plate D held by the first index 71, and functions as an inner plate cleaning control unit. 742 functions as a holding surface cleaning control section that causes the inclined side cleaning mechanism 723 to clean the inner plate D held by the second index 72.
Furthermore, in the present embodiment, the inner plate cleaning control unit 742 performs a deep cleaning operation that closely cleans the upper surface of the inner plate D by sliding the nonwoven fabric 724D along the upper surface of the inner plate D using the sliding mechanism 724H. Functions as a control unit.

According to this embodiment, the following actions and effects can be achieved.
(1) The inner plate cleaning device 7 causes the first index 71 to hold the side surface of the inner plate D, and then the bottom surface cleaning mechanism 713 Since the parallel side cleaning mechanism 714 is used to clean the inner plate D, the bottom surface of the inner plate D and the side surface different from the holding surface can be easily cleaned.
(2) The first index 71 holds the inner plate D by pinching the side surfaces of the inner plate D, so the inner plate D can be held securely, and the bottom cleaning mechanism 713 and the parallel side cleaning mechanism 714 It can be cleaned efficiently.
(3) After the inner plate cleaning device 7 causes the second index 72 to hold the inner plate D held by the first index 71, the holding surface of the inner plate D held by the first index 71 Since the inclined side surface cleaning mechanism 723 cleans the inner plate D, the entire surface of the inner plate D can be cleaned.

(4) The slider 712B of the first index 71 is located vertically above the chuck 712A of the first index 71, and the slider 722B of the second index 72 is located vertically above the chuck 722A of the second index 72. Since they are arranged vertically downward, the chuck 712A of the first index 71 and the chuck 722A of the second index 72 can be moved forward and backward without causing the first index 71 and the second index 72 to come into contact with each other. . In other words, the first index 71 and the second index 72 can hold the inner plate D at the same time, so the second index 72 can hold the inner plate D held by the first index 71 on the floor etc. You can receive it by holding it in the air without placing it down.

(5) The inner plate cleaning device 7 can roughly clean the surface of the inner plate D with the upper surface rough cleaning mechanism 702 and then closely clean the surface of the inner plate D with the upper surface fine cleaning mechanism 724. The surface of the inner plate D can be reliably cleaned.
(6) The upper surface rough cleaning mechanism 702 first cleans the upper surface of the inner plate D, and the upper surface fine cleaning mechanism 724 cleans the inner plate D using the bottom surface cleaning mechanism 713, the parallel side cleaning mechanism 714, and the inclined side cleaning mechanism 723. Since the top surface of the inner plate D is cleaned last after cleaning other surfaces different from the top surface, there is a risk that dirt may adhere to the top surface of the inner plate D when cleaning the sides and bottom of the inner plate D. Moreover, it is possible to eliminate the possibility that dirt from the upper surface of the inner plate D will adhere to the sides and bottom of the inner plate D after cleaning, and the upper surface of the inner plate D can be cleaned most carefully.
(7) The inner plate cleaning device 7 closely cleans the upper surface of the inner plate D by sliding the nonwoven fabric 724D along the upper surface of the inner plate D using the sliding mechanism 724H. For example, the surface of the inner plate D can be cleaned more carefully than when cleaning the surface of the inner plate D using a brush or the like.
