Background art

[0002] Various objects to be transported are transported by the transport device. In general, maintenance or maintenance of the transport device is performed manually by stopping the transport device. In particular, when the substrate breaks during transportation, or when replacing rollers on a roller conveyor, stop the transportation device during maintenance or maintenance, and remove the object to be transported on the transportation surface of the transportation device as necessary. Some parts were removed, a person stood beside the transport device, and the person was doing it from the side.

[0003] Furthermore, in a relatively small transport apparatus, maintenance, repair, or maintenance (hereinafter referred to as "maintenance personnel") stands on the side, so that maintenance, repair, or maintenance (hereinafter referred to as "maintenance") occurs. In a relatively large transport device, the physical characteristics of such maintenance personnel (for example, height, arm length, etc.) may require maintenance. In some cases, for example, when a stepladder is placed on the side, maintenance with a special jig must be performed, resulting in a decrease in work efficiency. In addition, depending on the type of maintenance, there is a case where an operation with a force just above is required at a predetermined position on the conveyance surface (for example, the central portion of the conveyance surface).

[0004] By the way, Patent Document 1 discloses a joint transport device for improving the efficiency of the work of attaching a joint to a steel pipe in a steel pipe sheet pile production line. In this apparatus, the joint conveying device is configured to convey a joint material in a direction perpendicular to the longitudinal direction of the joint material and provide a cross feed conveyor provided with a top plate for placing the joint material on the upper surface, and above the conveyor. In the longitudinal direction of the joint material, a plurality of gripping hands having a transport carriage capable of traveling in the longitudinal direction of the joint material and a torque-adjustable opening / closing means suspended so as to be lifted and lowered by the transport cart are provided. And a provided frame. In this way, using a transport cart in addition to the main transport device is efficient in supplying materials, etc., but this transport cart is not intended for maintenance personnel to work on. However, since it can be hung on the ceiling instead of the main transfer device, it is preferred for maintenance of the main transfer device.

Problems to be solved by the invention

[0006] In the present invention, in consideration of the background art and the prior art as described above, even if the transport apparatus is a transport apparatus, a transport apparatus and a transport system that can easily access a portion requiring maintenance, and the system. A carriage used in such a device or system is provided.

Means for solving the problem

[0007] In order to solve the above-described problem, the transport apparatus according to the present invention includes a movable maintenance carriage including a floor plate on which maintenance personnel can ride, and the floor plate or a floor plate support member that supports the floor plate crosses the transport direction In this way, the distance between the floor board and the transport surface is within a predetermined range even when the maintenance carriage is moved. In addition, the transfer system according to the present invention includes the transfer device and the maintenance cart as described above, and the maintenance cart is removed from the transfer device in accordance with the operation status of the transfer device. And maintenance in the present invention The cart can be used in the above-described transport device and transport system.

[0008] More specifically, the present invention can provide the following.

[0009] (1) A transport device that transports a plate-shaped body in a predetermined transport direction, the transport means for moving the plate-shaped body, and transport defined by the transport means at least in a virtual manner In a maintenance cart used in a transporting device comprising a surface and a support member that supports the transporting unit, a floor plate on which maintenance personnel can board, and a moving unit that allows the maintenance cart to move along the predetermined transporting direction And a floor plate support member that supports the floor plate from the moving means, the floor plate support member or the floor plate straddling the transport surface across the predetermined transport direction, and from the floor plate to the transport surface It is possible to provide a maintenance cart characterized in that it can move so that the distance of the vehicle falls within a predetermined range.

Here, the plate-like body may include, for example, a glass substrate having a particularly small thickness dimension compared to the length and width. In addition, a space where the plate-like object is located is necessary at a place where the plate-like body is conveyed, and the space (or surface) where the plate-like object is located can be called a virtual conveying surface. Further, a plane as a conveyance surface may actually be formed by a belt, such as a belt conveyor. In addition, since it may include the case where the surface as an entity is not formed, it is expressed as “at least”. The transport means may include any device that can move a transported object (that is, a plate-like body) directly or indirectly. For example, a contact-type drive device that is moved by contact, such as a roller or a belt, may be used to drive the object to be conveyed in a non-contact manner using a fluid such as a gas, such as an airflow levitation device or a conveyance device. May be. Furthermore, the object to be conveyed is levitated in an electromagnetic non-contact manner and

Include a non-contact type drive that drives in the Z or transport direction. Since the object to be conveyed is moved by the conveying means, the conveying surface is defined by the conveying means. The transport device moves the object to be transported along the transport surface. The transport means is supported by a support member that constitutes the transport device. Therefore, it can be said that the support member maintains the transport surface. Here, maintaining the conveyance surface may include that at least a virtual conveyance surface to be obtained is secured as a space. Therefore, the support member for maintenance directly forms the transport surface. There is no need to In general, any existing member such as a frame, a plate, a square member, or the like can be used as the support member, and each material may be a metal, an inorganic material, or an organic material.

[0011] A direction in which the plate-like body is transported is referred to as a transport direction. Here, the predetermined transport direction includes a direction in which the transport device tries to move the plate-like body and a direction along the direction. Here, in general, the direction may include forward and backward directions without considering the direction. The means for moving the maintenance carriage may include any device that enables the maintenance carriage to move at least in the transport direction. For example, existing technologies such as wheels, linear motors, belts and chains may be included. This moving means may function by engaging with a part of other parts of the transport apparatus. For example, wheels and rails. For example, the rails may include those that are fixed directly and Z or indirectly to the support member which is secured to the transport device. Rails may include those generally defined, for example, elongated plates, round bars, and noise. Moreover, even if the whole shape is not so, the case where the part exhibits such a shape may be included.

[0012] As described above, the transport direction may include both forward and rearward directions, but the traveling direction may mean the forward transport direction. The backward direction is the opposite of this direction of travel. The above-mentioned floor board is ultimately supported by the above-mentioned moving means via the floor board support member, and may be movable along the transport direction. At this time, the floor board support member or the floor board may straddle the transport surface across the predetermined transport direction. In the case of a river, the floorboard support member or floorboard may be passed to both sides so that a bridge is built from this side of the river that flows by force toward the downstream, which is the forward conveyance direction. At this time, the river surface corresponds to the transport surface, and the floating material such as wood floating on the river surface corresponds to the transported object. Here, the floorboard support member or floorboard, which is built like a bridge, rides on the moving means and can move downstream or upstream.

[0013] In general, maintenance personnel are not limited to human power, and can include robots, operation arms, and other devices that can be substantially the same as humans in maintenance. The floor board on which maintenance personnel can board may be of a size, strength, etc. that can hold maintenance personnel and attached items. Maintenance personnel are transporting means In order to perform maintenance of parts in the vicinity of the transfer surface of the transfer device, it is desirable that the distance to the floor plate force transfer surface on which maintenance personnel are placed is within the range where maintenance personnel can work. That is, the predetermined range from the floor board to the conveyance surface may be a distance range where maintenance personnel on the floor board can actually work. Further, it is more preferable that this distance is substantially constant as the maintenance carriage moves.

(2) The maintenance means according to (1), wherein the moving means includes a mechanism that allows the floor board to freely move to an arbitrary position on the transport surface.

[0015] This mechanism may be either automatic or manual. For example, the maintenance carriage may be moved by pulling the chain, or it may be moved by motor drive.

[0016] (3) The maintenance cart according to (1) or (2), wherein the moving means includes a mechanism that can be fixed at the arbitrary position.

[0017] The mechanism that can be fixed may be, for example, a stopper or a brake attached to the moving means which may be an anchor using a bolt or the like.

[0018] (4) The maintenance cart according to any one of (1) to (3) above, wherein the moving means moves on a rail provided in the transfer device.

[0019] The rail may be provided in the vicinity of at least one side of the transport surface (for example, along the side). Further, two rails may be provided along both sides of the transport surface. For stability, it is more preferable to provide two rails. It also includes rails along the transport direction in the transport surface, such as the center line that runs along the sides.

[0020] (5) The above-described (1) to (3), characterized in that it includes a support column that horizontally supports the floor plate, and the floor plate is installed higher than the transfer surface of the transfer device by the support column. We can provide the maintenance cart described in Crab.

[0021] (6) The maintenance cart according to claim 5, wherein the support is provided with a caster and further provided with a stagger to stop the movement of the caster.

[0022] Here, the caster includes any existing caster. For example, a baby caster may be used, and a caster used for a chair or the like may be included. In addition, the term “stop collar” as used herein may include a stopper and a Z or a brake generally used for these casters.

[0023] (7) The above (1) to (6), characterized in that it comprises a mechanism for retracting from the transport device. The maintenance cart described in any one of the above can be provided.

[0024] The maintenance cart may be permanently installed or provided only when necessary. That is, it may be easily removable from the transport apparatus that has undergone maintenance. As a mechanism for this purpose, for example, the carriage itself may have a removal mechanism, or a removal mechanism that can be separately installed in the transport device at any time.

[0025] (8) The maintenance cart according to any one of (1) to (6) above, further comprising means for preventing the maintenance personnel from falling.

[0026] The fall prevention means can include commonly used fall prevention members such as handrails, guards, fences, and wires. Other than that, include structures and mechanisms that can indirectly prevent falls.

[0027] (9) A maintenance method for a transport device that transports a plate-shaped body in a predetermined direction, the transport device supporting at least a virtual transport surface that transports the plate-shaped body and the transport surface. And a support member, and a maintenance carriage provided with a floor plate on which the maintenance personnel can board is moved on the conveyance surface, the maintenance carriage is stopped at a predetermined position, and the maintenance personnel are moved from the conveyance surface to the conveyance device. A maintenance method for maintenance can be provided.

BEST MODE FOR CARRYING OUT THE INVENTION

Next, embodiments of the present invention will be described with reference to the drawings. In the drawings, components having the same configuration or function and corresponding parts are denoted by the same reference numerals, and description thereof is omitted. In the following description, only one example of the embodiment according to the present invention is shown, and can be appropriately changed without exceeding the scope of the present invention based on the common general knowledge of those skilled in the art. Therefore, the scope of the present invention is not limited to these specific examples.

FIG. 1A is a perspective view showing a transport apparatus 10 that is an embodiment of the present invention. The conveying device 10 includes a roller conveyor 14 held by a plurality of support pillars 12, a rail 16 supported by the plurality of support pillars 12, and a carriage 18 force movably disposed on the rails. Is done. In the roller conveyor 14, a plurality of roller shafts 20 provided with a plurality of conveying rollers 22 are arranged in parallel and perpendicular to the conveying direction. These transport rollers 22 define a transport surface 24 on which a glass substrate 26 is disposed. Actually, when the glass substrate 26 is transported, the maintenance by the carriage 18 is not performed, and when the maintenance by the cart 18 is performed, the glass substrate 26 is not transported. In this figure, in order to show the relative positional relationship between the glass substrate 26 and the carriage 18, both are shown together. These roller shafts 20 are rotated by a roller belt 32 that is moved by driving of a motor 30 that is fixed to a CZV frame 28 disposed in the front in the drawing. In this way, the roller belt 32 is wound around each group at one end portion of each roller shaft 20.

The rail 16 is fixed by the support pillar 12 so as to be parallel to the transport surface 24 of the roller conveyor 14 and parallel to the transport direction. Accordingly, the rail 16 is provided in the vicinity of the side so as to be sandwiched between both sides of the transport surface 24 in parallel with the transport direction at a predetermined distance above the transport surface 24. The rail 16 is provided with a hole 34 so that a pin 36 (to be described later) can be inserted!

[0034] The dolly 18 has wheels 38 and 41 (see FIGS. 1A, 1D, and IE, and so on) on both sides. Each wheel 38, 41 can smoothly roll on each rail 16. In the center of the carriage 18, a floor board 40 is stretched, and maintenance personnel can get on it and work. Handrails 42 are provided at both ends of the traveling direction and backward direction of the carriage 18 so that maintenance personnel can be prevented from falling!

Next, a method for conveying the roller conveyor 14 will be described. As described above, the roller belt 32 is driven by the rotation of the motor 30 controlled by the control device (not shown) in each transport roller 22 of the roller conveyor 14 supported by the support pillars 12. Since the roller belt 32 is wound around the front end portion of each roller shaft 20, the roller belt 32 rotates in synchronization with each other, whereby the transport roller 22 rotates and the glass substrate 26 disposed on the transport surface 24 is moved. Transport in the transport direction. Incidentally, the roller shaft 20 is supported by the intermediate support portion 44 in the vicinity of the center, and the flat conveying surface 24 can be maintained. In the transport apparatus of this embodiment, the width of the transport surface perpendicular to the transport direction exceeds about 2 m. Standing on the side of this transfer device and considering the maintenance of parts on the transfer surface 24, which is set to a height of about lm, the range within which the maintenance personnel can reach is at most It is a little less than lm, and it is not easy to maintain the central part of the transport surface. It should be noted that an auxiliary device is disposed under the conveying surface 24 of the roller conveyor 14, and it is difficult to perform maintenance downward.

[0036] The rail 16 may be fixed to such a roller conveyor 14 at all times. This is because there is no particular hindrance to the conveyance of the glass substrate 26 that is the object to be conveyed. It may also be removed after maintenance is completed. As described above, it is more preferable that the rail 16 is arranged on the side (side) in parallel with the transport direction, avoiding the top of the transport surface as much as possible.

[0037] The rail 16 on the right side in the figure is open flat in a T shape with respect to the support frame 15.

The right rail is provided with a plurality of holes 34 at predetermined positions, so that the stop and fixing by the pins 36 of the carriage 18 can be easily performed at a desired position. The right wheel 41 (see FIG. 1D, IE) (not shown) of the carriage 18 is a flat wheel unlike the left wheel. On the other hand, the left rail 16 is also open in a T shape with respect to the support frame 15, but a triangular restraining rail 17 is used for the right wing. The wheel 18 that matches the restraining rail 17 enables the carriage 18 to move in parallel with the conveying direction. This cart 18 is a simple one that maintenance personnel can move by hand. It is also possible to equip the carriage 18 with a motor and a power source, and move the carriage 18 electrically.

FIG. 1B schematically shows the wheel 38 that matches the restraining rail 17. There is a wheel 38 on the right side of the wheel cover 39, and the left and right truncated cones 38A and 38B are fixed to each other with a thin disc-shaped member 38C in the center, and a piece-like wheel 38 having a recess in the center. Configure. Since the top of the restraining rail 17 enters this central recess, the wheel 38 rolls in parallel with the rail 16 and the carriage moves forward or backward.

[0039] The floor plate 40, which is the main floor of the carriage 18, is capable of being made of a particularly general material. It is desirable to design the floor board 40 in consideration of the maintenance personnel boarding it. The handrail 42 provided so as to sandwich the floor plate 40 is effective for preventing the fall, but it may become an obstacle when performing maintenance on the equipment in the transport surface directly below the carriage 18 and can be removed. More preferred to install.

[0040] The maintenance personnel who have boarded can work with both hands while standing on the floor plate 40 from the carriage 18 and facing their face to the transfer surface 24. At this time, the distance D from the floor plate 40 to the transfer surface 24 (see FIG. 1C) is a force that should be appropriately adjusted according to the work content. Generally, it is more preferable that the distance D is 10 to 40 cm. Is 20 to 30 cm. The size of the carriage 18 of this embodiment is about 104.5 cm in width (width in the direction perpendicular to the conveyance direction) and about 257 cm in length (length parallel to the conveyance direction). In addition, the height of the handrail is about 13.4 cm at 40 floors.

FIG. 1C is a partially enlarged view in which a part of the transport apparatus of FIG. 1 showing the glass substrate 26 (shown by a broken line) on the transport surface 24 and the floor plate 40 of the carriage 18 is broken. In this figure, the transparent glass substrate 26 is made opaque so that its position can be clearly grasped. As in the case of FIG. 1A, the glass substrate 26 and the floor plate 40 of the carriage 18 are shown in the same drawing in order to clarify their relative positions. As shown in FIG. 1A, in the transfer device having the transfer surface 24 for transferring the relatively large thin glass substrate 26, the peripheral portion of the side cannot be maintained by force S that can be maintained. However, it is clear that even if the height is adjusted with a stepladder that stands on the side, the center of the step cannot be reached. Therefore, in the transfer apparatus of the present invention shown in FIGS. 1A to 1C, the rail 18 is attached to the carriage 18 so that the carriage 18 is movable, so that maintenance is easily performed. In FIG. ID, the wheel 41 on the right side (the opposite side of the wheel 38) of the carriage 18 is indicated by an arrow AA. A normal flat wheel 41 different from the wheel 38 rides on the rail 16 and rotates to facilitate the movement of the carriage 18 in the conveying direction. The wheel may be the same type as the wheel 38. FIG. 1E is a front view of the wheel 41 of FIG. 1D. As is apparent from this figure, the wheel 41 is a flat type.

[0043] The transport apparatus 10 described above is mainly used in an environmental room such as a clean room or a constant temperature and humidity room. If it is a normal indoor transfer device, it may be unnecessary to prepare such a maintenance cart 18 for maintenance. This is because scaffolds and passages for maintenance personnel to stand can be provided directly in the transfer device itself, and maintenance personnel can get on the transfer device directly to perform maintenance. However, the effect of the carriage 18 is greatly exerted when the transport device becomes dirty by climbing or riding on the transport device, and as a result, there is a risk of contaminating the object to be transported during transport. In other words, the carriage 18 does not come into contact with the parts such as the transportation means or the nearby parts while being close to the parts near the transportation surface 24 of the transportation apparatus 10. For example, the use of such a carriage 18 is very significant for a transport device that transports FPD (flat 'panel display') or food as a workpiece.

FIGS. 2 to 5 are schematic views (perspective views) simply showing another embodiment of the present invention. The conveying device 110 in FIG. 2 shows a state in which a workpiece 126 that is an object to be conveyed is conveyed by a plurality of conveying rollers 122 supported by side frames 115 on both sides. The transport roller 122 is rotated by a driving device (not shown) (for example, a motor). The workpiece 126 substantially overlaps the conveyance surface, and it can be said that a virtual conveyance surface formed on the conveyance roller 122 is formed. FIG. 3 shows a state in which flat plates to be rails 116 are fixed to both side frames 115 in FIG. Such a transport device 111 can be provided with the rail 116 at all times, which is not particularly necessary for transporting the workpiece 126. This is not useful because it is only arranged narrowly on both sides of the virtual transport surface, but it does not become an obstacle. Such a transfer device 111 can omit the step of attaching the rail 116 in the transfer device maintenance method described below.

[0045] FIG. 4 shows that the work 126 conveyed in FIG. 3 is broken, and a carriage 118 is attached to remove the fragments. It shows where to open. Around the center of the workpiece 126, a crack 127A and a chip 127B due to a chip are shown. The cart 118 is provided with guards 142 on both sides of the transport direction and the reverse direction so that ribs are raised. Since this rib is low in height, it is not very effective in preventing maintenance personnel from falling, but it can prevent tools and screws on the floor plate 140 from accidentally falling onto the transport surface. The dolly 118 is provided with V and wheels (not shown) so as to roll on the respective rails 116 on both sides. FIG. 5 shows a state where the carriage 118 is attached to the transfer device 111. Similar to FIG. 1, the carriage 118 can move freely along the rail 116. In addition, if the presence of the carriage 118 does not hinder the conveyance of the cake 126, such a carriage 118 can be always installed. In this way, maintenance work can be easily performed.

FIG. 6 is a perspective view showing a transport apparatus 10A obtained by modifying the transport apparatus 10 shown in FIG. 1A.

Since the basic configuration of the deformed transfer device 10A is basically the same as that of the transfer device 10 shown in FIG. 1A, redundant description is omitted. The difference from the transfer apparatus 10 shown in FIG. 1A is that an auxiliary mechanism is added to the carriage 18 shown in FIG. 1A.

[0047] Since it is basically the same as the carriage 18 of FIG. The difference is that it has a structure that can move on the floor independently from the transfer device 10A. That is, under the floor plate 40, two hollow box-shaped beams (beams) 60, which are also configured with plate members extending in a direction perpendicular to the transport direction of the transport apparatus 10A, are passed so as to exceed the transport width, and the floor plate 40 is passed. It has a structure that supports it. The beam 60 is passed along both ends of the floor board 40 in the conveying direction, and can stably support the floor board 40. At both ends of the beam 60 in the conveyance width, hollow box-like columns 62, each of which is also composed of a plate member, are provided. Each column 62 extends substantially vertically downward to near the floor surface, and a caster 64 is rotatably disposed at the lower end thereof. The caster 64 can move on the floor in the front-rear and left-right directions, like casters such as strollers and chairs. The caster 64 is provided with a stuno 64A, and the movement of the rotating wheel of the caster 64 can be stopped.

In the state shown in FIG. 6, the casters 64 may contact the floor surface, but do not support all the loads of the carriage 18 and the auxiliary mechanism. The weight of the cart 18 and the auxiliary mechanism and the weight of maintenance personnel are mainly determined by the wheels 38 and 41 (see Fig. 1D and IE, the same shall apply hereinafter). It is supported. Accordingly, maintenance personnel operate and move the carriage 18 to perform maintenance in the same manner as described for the carriage 18 in FIG. 1A.

[0049] The carriage 18 and the auxiliary mechanism are separated from the transport apparatus 10A as necessary. That is, if the carriage 18 and the auxiliary mechanism are moved in the right direction (forward in the conveyance direction) in FIG. 6 and moved forward in the conveyance direction as they are, the wheels 41 and 38 are separated from the force rails 16 and 17, and the carriage 18 and The auxiliary mechanism is separated. When the wheels 41, 38 are detached from the rails 16, 17, all the loads of the carriage 18 and the auxiliary mechanism are supported by the columns 62 and casters 64.

[0050] FIG. 7 is a diagram in which a moving gantry 70 is arranged in the transport direction in the same transport apparatus 10 as the transport apparatus 10 shown in FIG. 1A. The movable platform 70 is placed in the same plane with the rail 16 and the restraining rail 17 of the transfer device 10 (the flush and the flush should fit on the same plane! Prepare the rails 72 and 74 to extend in the same direction. These rails 72 and 74 are held by a plate material as a beam extending in the direction of the conveyance width, and form a well shape. The well is supported by hollow struts 76 made of the four plates below it, and casters with stoppers 78, which are the same as the casters with stoppers 64 of FIG. Note that stoppers 73 and 75 are disposed at the ends (right end in the figure) of the rails 72 and 74, and the wheels 38 and 38A of the carriage 18 that has moved can be stopped. In addition, the rails 72 and 74 are provided with an overhang portion so that the rails 16 and the constraining rail 17 and the rails 72 and 74 can be arranged close to each other so that the movable frame can be arranged.

FIG. 8 shows a method for removing the carriage 18 from the transfer apparatus 10 using the above-described moving mount 70. In the carriage 18 indicated by the broken line, the force wheels 41 and 38 provided on the transport device 10 rotate on the rails 16 and 17 and move to the right in the figure. The wheels 41 and 38 move from the rails 16 and 17 onto the rails 72 and 74, which are in a relationship with each other. At this time, if there is a large gap between the rails 16, 17 and the rails 72, 74, the movement is restricted. Therefore, it is preferable to dispose the moving base 70 so as not to leave a gap.

As shown in FIG. 8, when the carriage 18 is completely on the moving stand 70, the stagger of the casters 78 of the moving stand 70 is removed, and the moving stand 70 is moved away from the transfer device 10. By providing such a movable gantry 70, a maintenance trolley can be attached to and detached from the transfer device 10 as necessary. FIG. 9 is a perspective view showing a transport apparatus 10B obtained by modifying the transport apparatus 10 shown in FIG. 1A. Since the basic configuration of the modified transfer device 10B is basically the same as that of the transfer device 10 shown in FIG. 1A, redundant description is omitted. The difference from the transfer apparatus 10 shown in FIG. 1A is that the carriage 80 shown in FIG. 1A is changed. However, the mechanism for moving the carriage 80 is the same as that of the carriage 18 described above, and the wheels 38 and 41 (see FIGS. 1A, 1D, and IE, the same applies hereinafter) are used as the moving means.

The carriage 80 is held movably on the rails 17 and 16 by the wheels 38 and 41. The wheels 38 and 41 are fixed and supported by frame members along both sides of the conveying surface 24 of the carriage 80. This frame member is adjacent to a support member 82 that is bridged across the transport surface 24 at each end (ie, before and after in the transport direction). The handrails 42 are attached to the support members 82, respectively. Further, the support member 82 is provided with a slide mechanism which can be driven by a chain 86 having both ends stretched by a gear 84. A floor plate 40A that slides in the groove by the slide mechanism is provided. Maintenance personnel can get on the floor board 40A, grab the handrail, and move the position of the floor board 40A substantially perpendicular to the conveying direction. That is, the wheels 41 and 38 as moving means can be used in the transport direction, and a slide mechanism can be used in the direction perpendicular to the transport direction. By adopting such a structure, it is possible to move on the transport surface more finely, and maintenance can be performed more easily.

[0055] As described above, in the transfer device (maintenance auxiliary mechanism) of the present invention, even if the transfer device has a wide transfer surface, maintenance personnel can perform maintenance work at a desired position on the transfer surface. Can be done easily. In addition, maintenance work can be performed directly above the transfer surface.
