  A first embodiment of the present invention will be described with reference to FIGS.

  In FIG. 1 and FIG. 2, reference numeral 1 denotes a stacking device that is a transport device. The stacking device 1 is, for example, a group of articles (conveyed objects) A having a predetermined alignment pattern by a plurality of articles A1 while conveying the articles A1. And a palletizer (stacking equipment) for stacking the formed article group A on the pallet P in a plurality of stages. The article A1 is a cardboard case, for example, and the article group A is composed of, for example, eight articles A1.

  The stacking apparatus 1 is configured to form an article group A by aligning a predetermined alignment pattern while conveying an article conveying means 2 that conveys an article A1 and a plurality of articles A1 that are sequentially supplied from the article conveying means 2. Group forming means 3.

  The article group forming means 3 includes a direction changing unit 4, an alignment pattern forming unit 5 that is a sorting unit, a first roller conveyor unit (first layer conveyor) 6, and a second roller conveyor unit (second layer conveyor). 7 and a pair of guide plates 8 that are horizontally rotatable so as to be in contact with and away from the side surface of the article group A on the second roller conveyor unit 7.

  In addition, the stacking apparatus 1 receives the article group A from the second roller conveyor unit 7 of the article group forming means 3 and conveys the article group A, and receives the article group A from the conveyor means 9. A support conveyance means (carriage) 10 which is a transfer means for transferring and conveying the sheet in a horizontal direction up to a predetermined position (loading position) is provided. These conveying means 9 and support conveying means 10 convey the article group A in the same conveying direction as shown in FIGS. In addition, the direction of the arrow shown in FIG. 3 is demonstrated below as the front-back direction and the left-right direction.

  As shown in FIGS. 3 and 4, the transport unit 9 includes a transport chain 11 which is a plurality of parallel endless transport bodies that transport the article group A by rotating on the upper surface. The plurality of transport chains 11 are longitudinal in the front-rear direction and are arranged at equal intervals in the left-right direction. The transport end side, which is the front end side of each transport chain 11, is wound around the drive sprocket 12, and the transport start end side, which is the rear end side of each transport chain 11, is wound around the driven sprocket 13.

  Then, when the transport chain 11 rotates in a predetermined direction based on the power from the chain rotation motor 14 that is the driving means, the forward path portion of the transport chain 11 travels on the chain rail 15, and on the upper surface of the traveling forward path portion. The article group A is conveyed until it contacts the plate-like stopper 16. The stopper 16 is attached to the front end portion of the conveying means 9.

  Further, the transport chain 11 can be turned up and down around the axis of the driven sprocket 13 so that the transport end side is moved up and down by the operation of the chain lifting cylinder 17 as drive means. For this reason, when the transport chain 11 is rotated downward based on the operation of the chain raising / lowering cylinder 17 to be inclined forward and downward, the article group A on the forward path portion of the transport chain 11 is placed on the support 21 of the support transport means 10. (See Fig. 5).

  As shown in FIGS. 3 to 5 and the like, the supporting and conveying means 10 is horizontally arranged between a receiving position (rear position) as a first position and a loading position (front position) as a second position. The article group A is received from the transport chain 11 of the transport means 9 and placed and supported in a state where the article group A is positioned at the receiving position, and the placed and supported article group A is loaded from the receiving position to the loading position. It is transferred and transported by horizontal movement.

  The receiving position is a position that overlaps the transport chain 11 in a side view, and the loading position is a position above the pallet P and a position that overlaps the pallet P in a plan view.

  The support / conveying means 10 has a plurality of support bodies 21 that are longitudinally parallel to each other in the longitudinal direction for placing and supporting the article group A, which is an object to be conveyed, on the upper surface. The plurality of supports 21 can be horizontally moved simultaneously between the receiving position and the loading position, for example, by the operation of the driving motor 20 which is one driving means. Further, like the transport chain 11, the plurality of support bodies 21 are arranged at equal intervals in the left-right direction, and can be inserted into and removed from the gap between the transport chains 11 adjacent to each other. Note that the gaps between the supports 21 adjacent to each other are not necessarily equal.

  The front end portion of the support body 21 is fixed to a tilt plate 23 for hooking prevention having a forward and downward inclined shape that is formed in a longitudinal direction in the left-right direction. Guide guides 25 that run on the guide rails 24 are provided at both ends in the longitudinal direction of the inclined plate 23. A bearing 27 that is a rotating member that travels on the bearing travel rail 26 is attached to the rear end portion of the support 21.

  On the other hand, the apparatus frame 30 is provided with front and rear pulleys 31 that are opposed to each other, and a timing belt 32 that is an endless body is stretched around the pulleys 31, and the inclined plate 23 is attached to the timing belt 32. It is fixed. When the timing belt 32 rotates based on the power from the drive motor 20, the rotation of the timing belt 32 causes the plurality of supports 21 to horizontally move simultaneously between the receiving position and the loading position.

  Further, the stacking device 1 contacts the rear surface (rear surface) of the article group A and moves rearward of the article group A when the plurality of supports 21 of the support conveyance means 10 move horizontally from the loading position to the receiving position. Is provided with a back stopper 41 which is a restricting means for restricting the horizontal movement.

  The back stopper 41 is provided so as to be pivotable in the vertical direction about a horizontal support shaft (not shown) in the horizontal direction. The back stopper 41 is a back stopper driving means (not shown) which is a driving means such as a cylinder. Based on the power from the center, it rotates between the restricting position and the retracted position around the support shaft. The back stopper 41 is in a state of being positioned at the regulation position, and abuts against the back surface of the article group A at the loading position to regulate the back position of the article group A. The restriction position by the back stopper 41 can be adjusted by operating the back stopper adjustment handle, for example.

  Further, the loading device 1 contacts the front surface (front surface) of the article group A to restrict the front position of the article group A and the side position of the article group A by contacting the side face of the article group A. Left and right side stoppers (not shown) for regulation are provided.

  Each side stopper is horizontally movable in the left-right direction, which is a direction orthogonal to the moving direction of the plurality of supports 21, and is regulated based on power from a side stopper driving means (not shown) that is a driving means such as a cylinder. Move horizontally between position and retracted position. The restriction position by the front stopper 46 can be adjusted by operating the front stopper adjustment handle. Similarly, the restriction position by the side stopper can also be adjusted by operating a side stopper adjustment handle (not shown).

  It should be noted that the front front stopper 46, the left and right side stoppers, and the rear back stopper 41 are directed toward the pallet P or the article group A already stacked on the pallet P when the article group A is stacked. Four-surface outer periphery guide means (lock device) 40 for guiding the fall of the article group A along the vertical direction is configured. The four-surface outer periphery guide means 40 also corrects the deviation of the article group A.

  Further, the stacking apparatus 1 includes a pallet lifting body 47 that lifts and lowers the pallets P on which the article group A is sequentially stacked. The pallet P is placed on the pallet elevating body 47, and the article group A is stacked on the pallet P on the pallet elevating body 47. A pallet carry-in conveyor 48 for carrying an empty pallet (empty pallet) P to the pallet lift 47 is disposed on the upstream side of the pallet lift 47, and on the downstream side of the pallet lift 47. A pallet unloading conveyor 49 for unloading the pallet (actual pallet) P in which the article group A is stacked in a predetermined number of stages from the pallet lifting body 47 is disposed.

  Here, the stacking device 1 is moved when the support transport means 10 horizontally moves forward from the receiving position to the stacking position with the plurality of supports 21 placing and supporting the article group A having a predetermined alignment pattern. The article group A on the support 21 does not shift backward with respect to the support 21 of the support transport means 10 due to inertia.

  As shown in FIGS. 6 to 9, each support body 21 of the support transport means 10 has a square pipe portion 51 that is a hollow support body portion that is longitudinal in the front-rear direction and has a rectangular cross section. A flat plate-like upper plate portion of the square pipe portion 51 is a longitudinal and horizontal support surface portion 52 in which the article group A is placed and supported on the upper surface. A plurality of rectangular holes 53 arranged at intervals in the longitudinal direction of the support surface portion 52 are formed in the support surface portion 52 so as to penetrate the upper and lower surfaces of the support surface portion 52.

  The plurality of hole portions 53 are dispersed at regular intervals over substantially the entire length of the longitudinal support surface portion 52 so as to face all of the plurality of articles A1 constituting one article group A on the support conveying means 10, for example. Is formed. Note that the gaps between the adjacent hole portions 53 are not necessarily equal, and the size of the gap may be changed depending on, for example, the shape of the conveyed object.

  The hole 53 is, for example, slightly long in the longitudinal direction of the support surface 52, and the width of the hole 53 is slightly smaller than the width of the support surface 52. The size of the hole 53 is, for example, 100 mm × 50 mm, but is not limited to this dimension. Further, for example, the hole 53 is formed only on the rear end side (the rear end side in the movement direction to the loading position) of the support surface portion 52 so as to face only the article A1 on the rear end side of the article group A. Good. That is, for example, two holes 53 may be opposed to one article A1 on the rear end side of the article group A, and when the number of articles A1 at the rear end position is three, holes are provided. The number of parts 53 is six.

  Further, the support conveying means 10 does not contact the article group A placed and supported on the support surface portion 52 in the state before the expansion deformation, and the article group placed and supported on the support surface portion 52 in the state after the expansion deformation. A plurality of inflatable rubbers (elastic bodies) 55 which are a plurality of elastically deformable deformation preventing portions that prevent the displacement of the article group A by pressing in contact with the portion facing the hole 53 in the lower surface of A. Have.

  The expansion rubber 55 is disposed one by one in the square pipe portion 51 of the support 21 so as to correspond to each hole 53, and is located immediately below the corresponding hole 53. The inflatable rubber 55 is, for example, a bag-like material made of an elastic body. Based on this, it returns to its original shape and exits from the hole 53. Note that the coefficient of friction of the surface of the expanded rubber 55 is larger than the coefficient of friction of the surface of the support surface part 52.

  The expansion rubber 55 is attached to a rubber attachment body 56 made of metal, for example. The rubber mounting body 56 is connected to air supply / discharge means 57 for supplying air into the expanded rubber 55 and discharging air from the expanded rubber 55. The air supply / discharge means 57 has, for example, one air supply / exhaust blower 58 and a connection pipe (supply / exhaust pipe) 59 connected to the blower 58, and the downstream end portion of the connection pipe 59 is made of each rubber. It is connected to the attachment body 56. As shown in FIG. 3, a part of the connection pipe 59 connected to the blower 58 is disposed in a pipe 60 that is a cylindrical portion having a longitudinal direction fixed to the lower surface side of the inclined plate 23. Has been. The blower 58 is switched between air supply and discharge by a switching valve.

  Further, as shown in FIGS. 6 and 7, each support body 21 of the support conveyance means 10 prevents the article group A from dropping from the support surface portion 52 when moving from the receiving position to the loading position. The rear end portion has an inclined surface portion 61 that is a forward and downward inclined fall prevention portion.

  The inclined surface portion 61 is constituted by, for example, a plate-shaped inclined rubber 62 that is inclined forward and downward toward the support surface portion 52 side. The inclined rubber 62 is baked and welded to the upper surface of, for example, a metal inclined plate 63 so as to cover the entire upper surface. The inclined plate 63 is fixed to the rear end portion of the square pipe portion 51. A through hole 64 is formed in the overlapping inclined rubber 62 and inclined plate 63, and the upper portion of the bearing 27 is inserted into the through hole 64.

  Next, the operation of the loading device 1 will be described with reference to the drawings.

  As shown in FIG. 5 (a), the article group A which is an article to be conveyed aligned in a predetermined alignment pattern by the article group forming means 3 is a plurality of conveying chains in a horizontal state from above the second roller conveyor unit 7. 11 is transferred to the forward direction of the plurality of rotating transport chains 11 and is transported in a predetermined direction (forward) and stopped by contact with the protruding stopper 16 to reach a desired position. Positioned.

  At this time, the forward paths of the plurality of transport chains 11 are positioned at the same height as the upper surface of the second roller conveyor section 7, and the support surface portions 52 of the plurality of supports 21 are slightly more than the forward paths of the transport chains 11. At the lower receiving position, it is inserted between the conveying chains 11 adjacent to each other on the left and right.

  Next, as shown in FIG. 5 (b), when the plurality of transport chains 11 turn downward about the rear end portion based on the operation of the chain lifting / lowering cylinder 17, the plurality of transport chains 11 are inclined downward from the horizontal state. The article group A on the forward path portion of the transport chain 11 is transferred onto the support surface portions 52 of the plurality of support bodies 21. That is, the support body 21 of the support transport means 10 receives the article group A from the transport chain 11 and places and supports it in a state of being positioned at the receiving position.

  Next, as shown in FIG. 5C, with the back stopper 41 and the side stopper positioned at the retracted position, the plurality of supports 21 support the article group A and move forward from the receiving position to the loading position. The article group A is transported in the same direction as the transport direction of the transport means 9 by horizontally moving to. That is, the article group A is transferred from the receiving position to the loading position by the support conveyance means 10.

  When the supporting and conveying means 10 moves from the receiving position to the loading position, the expansion rubber 55 expands and deforms based on the supply of air by the air supply / discharge means 57 and the hole 53 in the lower surface of the article group A The article group A on the support surface portion 52 of the support 21 of the support transport means 10 does not shift backward due to inertia with respect to the support surface portion 52. Move forward with 52.

  Then, after the support 21 arrives at the loading position and the front surface of the article group A comes into contact with the front stopper 46, the rear stopper 41 rotates to the regulation position and comes into contact with the rear face of the article group A, and the side surface The stopper moves horizontally to the regulation position and contacts the side surface of the article group A. Further, the expanded rubber 55 returns to its original shape by the elastic restoring force based on the discharge of air by the air supply / discharge means 57, and is away from the lower surface of the article group A and is not in contact with the article group A.

  Next, in this state, as shown in FIG. 5 (d), when the plurality of support bodies 21 horizontally move backward from the loading position to the receiving position, the article group A moves relative to the support surface portion 52 of the support body 21. As a result, it slides and moves relatively. As a result, it is slightly dropped while being guided by the four-surface outer periphery guide means 40, and placed on the pallet P or the uppermost article group A already stacked on the pallet P. . By repeating such an operation, a plurality of article groups A are sequentially stacked on the pallet P, but the completed stacking work is unloaded from the pallet lifting / lowering body 47 by the pallet unloading conveyor 49. An empty pallet P is carried into the pallet elevating body 47 from the carry-in conveyor 48.

  Then, according to the stacking device 1, the article group A does not deviate from the support / conveyance means 10 when the support / conveyance means 10 moves from the receiving position to the loading position with the article group A placed and supported. Therefore, even if the moving speed of the supporting and conveying means 10 is increased when moving from the receiving position to the loading position for high-speed processing, the article group A does not shift with respect to the supporting and conveying means 10. , The processing capacity can be improved.

  Further, only when the support conveyance means 10 moves from the receiving position to the loading position, the expansion rubber 55 for preventing slippage, that is, for preventing slippage, is inflated and deformed, so that a hole is formed in the lower surface of the article group A on the support surface 52. Since the contact with the portion facing 53, it is possible to effectively prevent the rearward shift of the article group A at the time of transfer by the support 21, thereby preventing the back stopper 41 from being bitten, the article A1 being damaged, etc. Can be prevented.

  The deforming portion for preventing deviation is not limited to the expanding rubber 55 that expands and deforms, and may be, for example, a member that bends and deforms, a member that stretches and deforms, or the like. Further, the deforming portion is not limited to the one that is disposed in the support body 21 and advances and retreats with respect to the hole portion 53, and may be one that is disposed between the support bodies 21 adjacent to each other, for example.

  Next, a second embodiment of the present invention will be described with reference to FIGS.

  In the stacking apparatus 1 according to the second embodiment, unlike the first embodiment, the support conveyance means 10 is arranged between a contact position (upper position) and a non-contact position (lower position). It is movable in the vertical direction and does not come in contact with the article group A placed and supported on the support surface portion 52 in the state where it is located at the non-contact position, and is placed on the support surface portion 52 when it is located in the contact position. A lifting rubber (a plurality of elastically deformable displacement preventing parts that prevent the deviation of the article group A by pressing and contacting the portion of the lower surface of the article group A that faces the hole 53 in a planar shape. Elastic body) 71.

  The elevating rubber 71 is disposed one by one in the square pipe portion 51 of the support 21 so as to correspond to each hole 53, and a part thereof is located in the corresponding hole 53. The elevating rubber 71 is, for example, a rectangular plate made of an elastic body, and is formed to have approximately the same size as the hole 53. Note that the friction coefficient of the surface of the elevating rubber 71 is larger than the friction coefficient of the surface of the support surface portion 52.

  The elevating rubber 71 is attached to a moving means 72 that moves the elevating rubber 71 between a contact position and a non-contact position. The moving means 72 is, for example, a bag-like expansion rubber 73 that can be inflated and deformed, and an elevating rubber 71 is fixed to an upper surface portion of the expansion rubber 73.

  When the expansion rubber 73 expands and deforms based on the supply of air to the inside thereof, the elevating rubber 71 rises from the non-contact position to the contact position and presses and contacts the lower surface of the article group A. Further, when the expansion rubber 73 returns to its original shape by the elastic restoring force based on the discharge of air from the inside thereof, the elevating rubber 71 descends from the contact position to the non-contact position and leaves the lower surface of the article group A.

  In addition, the expanded rubber 73 is attached to, for example, a metal rubber mounting body 56 like the expanded rubber 55 of the first embodiment, and the rubber mounting body 56 is supplied with air into the expanded rubber 73. An air supply / discharge means 57 that discharges air from the inside of the expanded rubber 73 is connected. The air supply / discharge means 57 has, for example, one air supply / exhaust blower 58 and a connection pipe 59 connected to the blower 58, and the downstream end of the connection pipe 59 is connected to each rubber mounting body 56. It is connected. In addition, the other structure of this loading apparatus 1 is fundamentally the same as the said 1st Embodiment.

  Even in such a stacking apparatus 1, the article group A is displaced with respect to the support conveyance means 10 when the support conveyance means 10 moves from the receiving position to the loading position while the article group A is placed and supported. Therefore, even if the moving speed of the supporting and conveying means 10 is increased when moving from the receiving position to the loading position for high-speed processing, the article group A does not deviate from the supporting and conveying means 10. Therefore, the processing capability can be improved.

  Further, only when the support conveying means 10 moves from the receiving position to the loading position, the lifting / lowering rubber 71 for preventing slippage, that is, for preventing slipping, moves to the contact position based on the operation of the moving means 72 and moves on the support surface portion 52. Of the lower surface of the product group A, the portion facing the hole 53 is effectively prevented from rearward shifting of the product group A at the time of transfer by the support 21, and therefore the back stopper 41 is bitten. Etc., and damage to the article A1 can be prevented.

  The moving means 72 is not limited to the air-type expansion rubber 73, and may be, for example, a cylinder, a motor, a diaphragm, or the like, and the moving unit such as the lifting rubber 71 is placed between the contact position and the non-contact position. Any means can be used as long as it can be moved with the.

  Further, the moving unit for preventing the shift is not limited to the plate-like lifting rubber 71, and may be, for example, a member made up of a large number of rubber protrusions, a non-rotatable rubber roller, or the like.

  Furthermore, the moving part is not limited to the one provided in the support body 21, and may be, for example, one provided between the support bodies 21 adjacent to each other, and the movement of the moving part may be rotated. .

  Next, a third embodiment of the present invention will be described with reference to FIGS.

  In the loading device 1 according to the third embodiment, unlike the first embodiment, the support transport means 10 is provided on the support surface portion 52 of the square pipe portion 51 having the internal space portion 51a inside. It has intake / exhaust holes 81 which are a plurality of circular holes formed through the upper and lower surfaces of the support surface 52 so as to communicate with the internal space 51a.

  The plurality of intake / exhaust holes 81 are distributed over substantially the entire surface of the longitudinal support surface 52 so as to face all of the plurality of articles A1 constituting one article group A on the support / conveying means 10, for example. Are formed in a matrix. The intake / exhaust hole 81 is, for example, a circular hole having a diameter of 1 mm (φ1) to a diameter of 2 mm (φ2), but is not limited to this dimension. Further, for example, an intake / exhaust hole 81 is formed only on the rear end side (the rear end side in the movement direction to the loading position) of the support surface portion 52 so as to face only the article A1 on the rear end side of the article group A. Other configurations may be used. That is, for example, when the number of articles A1 at the rear end position is three, the intake / exhaust hole 81 may be formed so as to face only the three articles A1, for example, by a dotted line in FIG. A configuration in which the intake / exhaust hole 81 is formed only in the enclosed range E may be employed. In this way, by forming the intake / exhaust hole portion 81 only in a part of the support surface portion 52, for example, it is possible to reduce the size of the blower 58, simplify piping wiring, save labor in hole processing, and the like. Become.

  In addition, the stacking device 1 includes air supply / discharge means 57 that supplies and discharges air to and from the internal space 51a of the square pipe 51 of each support 21. The air supply / discharge means 57 includes, for example, one air supply / exhaust blower 58 and a connection pipe 59 connected to the blower 58, and a downstream end portion of the connection pipe 59 is connected to the pipe 60. The inside of the pipe 60 communicates with the internal space 51a of the square pipe 51 of each support 21 (see FIG. 3).

  Then, when the support conveyance means 10 moves from the receiving position to the loading position, the support surface portion 52 is based on the negative pressure of the intake / exhaust hole portion 81 due to the discharge of air from the internal space portion 51a of the square pipe portion 51. And the article group A increase in friction. That is, the operation of the blower 58 such as a blower generates negative pressure in the internal space 51a and the intake / exhaust hole 81, and external air is sucked from the intake / exhaust hole 81 into the internal space 51a of the square pipe 51. As a result, the article group A is adsorbed and fixed to the support surface portion 52. For this reason, when the support transport means 10 is moved, inertia acts on the article group A, but the article group A does not move relative to the support surface portion 52.

  Further, when the support conveying means 10 moves from the loading position to the receiving position, the support surface portion 52 is based on the positive pressure of the intake / exhaust hole portion 81 due to the supply of air to the internal space portion 51a of the square pipe portion 51. And the friction between the article group A is reduced. That is, positive pressure is generated in the internal space 51a and the intake / exhaust hole 81 by the operation of the blower 58 such as a blower, and the air in the internal space 51a is discharged (spouted) from the intake / exhaust hole 81, and as a result. Then, the suction and fixation of the article group A with respect to the support surface portion 52 is released, and a vertically upward external force is applied to the article group A. For this reason, when the support conveying means 10 moves, the article group A has improved slipperiness with respect to the support surface portion 52, moves relative to the support surface portion 52, and moves from the support surface portion 52 to the pallet P. It falls onto the article group A stacked on the top or pallet P. In addition, the other structure of this loading apparatus 1 is fundamentally the same as the said 1st Embodiment.

  Even in such a stacking apparatus 1, the article group A is displaced with respect to the support conveyance means 10 when the support conveyance means 10 moves from the receiving position to the loading position while the article group A is placed and supported. Therefore, even if the moving speed of the supporting and conveying means 10 is increased when moving from the receiving position to the loading position for high-speed processing, the article group A does not deviate from the supporting and conveying means 10. Therefore, the processing capability can be improved.

  Further, when the support conveyance means 10 moves from the receiving position to the loading position, the article group A is attracted and fixed to the support surface portion 52, and the friction between the support surface portion 52 and the article group A is increased. The rearward shift of the article group A at the time of transfer by 21 can be effectively prevented, so that the back stopper 41 can be prevented from being bitten, and the article A1 can be prevented from being damaged.

  Further, when the support conveying means 10 moves from the loading position to the receiving position, the air ejected from the intake / exhaust hole 81 hits the lower surface of the article group A and the friction between the support surface part 52 and the article group A is caused. Therefore, the article group A can be easily slipped with respect to the support surface portion 52, the load on the article group A can be reduced, and, for example, the non-slip-coated article paste adheres to the surface of the support surface portion 52. Can be prevented.

  For example, when the support conveying means 10 moves from the loading position to the receiving position, the article group A may be slightly lifted from the support surface portion 52 by the air discharged from the intake / exhaust hole 81.

  In each embodiment, for example, the conveyance direction of the conveyance unit 9 and the conveyance direction of the support conveyance unit 10 may be orthogonal to each other in a plan view, and the conveyance unit 9 further includes a plurality of conveyance chains 11. It is not limited to a chain conveyor, but may be a roller conveyor having a plurality of conveying rollers.

  Further, the configuration is not limited to the configuration in which the support conveyance means 10 such as a carriage fork moves linearly between the receiving position and the loading position. For example, the configuration in which the support conveyance means 10 moves (rotates) in a curved line, etc. But you can.

  Further, the object to be conveyed that is conveyed by the support conveyance means 10 placed on the support surface portion 52 may be, for example, one article, or a bag other than a cardboard case, a can, a bottle, a plastic bottle, or the like.

  Furthermore, the stacking apparatus 1 that stacks the transported object after transporting the transported object has been described as an example of the transport apparatus. However, the present invention is not limited to this. For example, a transfer apparatus that simply transfers the transported object to a predetermined position may be used. .
