<Tray 20>
Next, the tray 20 will be described in detail with reference to FIGS. 4 to 6. FIG. 4 is a schematic perspective view showing the tray 20 according to the embodiment. FIG. 5 is a schematic plan view showing the tray 20 according to the embodiment. FIG. 6 is a schematic side view showing the tray 20 according to the embodiment. In FIG. 5, the article 200 (here, a book) placed on the bottom plate portion 22 is shown by a virtual line. The article 200a indicates an article having an upper limit size to be handled by the article automatic handling device 10. Further, the article 200b indicates an article having a lower limit size to be handled by the article automatic handling device 10. Further, in the X, Y, Z directions in FIGS. 4 to 6, the above X, Y, in FIGS. 1 to 3 in a state where the tray 20 is located at the storage unit 30 or the handling port mechanism 40 in the article automatic handling device 10. It corresponds to the Z direction.

The tray 20 is a tray for the article automatic handling device 10. The tray 20 is conveyed between the storage unit 30 and the handling port 40h by the conveying mechanism 70 in the article automatic handling device 10. The tray 20 includes a mounting portion 21 and a receiving portion 25.

The mounting portion 21 is a portion on which the article 200 is placed. The mounting portion 21 includes a bottom plate portion 22. Here, the mounting portion 21 further includes a side plate portion 23 and an article stopper 24. Further, here, a hole 22h is formed in the bottom plate portion 22.

The bottom plate portion 22 is provided so that the article 200 can be placed on it. The tray 20 is used in a state where the largest main surface of the bottom plate portion 22 is parallel to the horizontal direction (direction perpendicular to the direction of gravity). The bottom plate portion 22 is formed in a rectangular shape (here, a rectangular shape) in a plan view. Therefore, the bottom plate portion 22 includes four edge portions 22a, 22b, 22c, and 22d. The edges 22a and 22b are the edges of the short sides of the rectangle, and the edges 22c and 22d are the edges of the long sides of the rectangle. A recess 22e is formed in the bottom plate portion 22. The recess 22e is formed in the edge 22a. The edge portion 22a is the first edge portion.

The recess 22e is formed so as to be recessed toward the edge 22b on the opposite side of the edge 22a. The recess 22e is provided in the middle portion of the edge portion 22a along the extending direction. The end of the edge 22a along the extending direction is not recessed. The recess 22e is formed in an isosceles trapezoidal shape in a plan view. The portion corresponding to the corner of the isosceles trapezoid may be rounded. The recess 22e is recessed so that the width of the opening is larger than the width of the bottom. The edge of the recess 22e that connects the opening to the bottom is not parallel to the edges 22b, 22c, 22d. The edge of the recess 22e, which forms the bottom of the recess 22e, is parallel to the edge 22b. It is not essential that the recess has the above shape. The concave portion may be concave in a square shape or may be concave in an arc shape in a plan view.

The back surface of the bottom plate portion 22 at the edge portion 22a is an inclined surface. As a result, when the tray 20 is transferred while sliding from the edge 22a side to the table or the like, it is possible to prevent the corner of the tray 20 from coming into contact with the corner of the table and causing a transfer error.

The side plate portion 23 prevents the article 200 placed on the bottom plate portion 22 from falling off from the edge portions 22b, 22c, 22d. The side plate portion 23 is provided so as to project above the bottom plate portion 22. The side plate portion 23 is provided on the edge portions 22b, 22c, 22d other than the edge portion 22a of the bottom plate portion 22. Here, side plate portions 23 are provided on each of the three edge portions 22b, 22c, and 22d other than the edge portion 22a. Hereinafter, when it is necessary to distinguish between the three side plate portions 23, reference numerals are given to the provided edge portions 22b, 22c, 22d, and the three side plate portions 23 may be referred to as side plate portions 23b, 23c, 23d.

The side plate portion 23b is provided on the edge portion 22b opposite to the edge portion 22a. The side plate portion 23b is provided all over along the extending direction of the edge portion 22b. The side plate portion 23b may be partially provided along the extending direction of the edge portion 22b. The side plate portions 23c and 23d are provided on the edge portions 22c and 22d connecting the edge portions 22a and 22b, respectively. The side plate portions 23c and 23d are provided all over along the extending direction of the edge portions 22c and 22d. The side plate portions 23c and 23d may be partially provided along the extending direction of the edge portions 22c and 22d. The side plate portions 23c and 23d are connected to the side plate portions 23b.

The side plate portions 23b, 23c, and 23d are continuous at a constant height, except for the rounded portions at the end portions of the side plate portions 23c, 23d. However, in the side plate portions 23b, 23c, and 23d, there may be portions having different heights other than the above. The heights of the side plate portions 23b, 23c, and 23d are the same. However, the heights of the side plate portions 23b, 23c, and 23d may be different. The side plate portions 23b, 23c, and 23d are provided perpendicular to the bottom plate portion 22. However, the side plate portions 23b, 23c, and 23d may be provided so as to intersect the bottom plate portion 22 at an angle other than vertical.

The article stopper 24 prevents the article 200 from falling off from the edge portion 22a side of the bottom plate portion 22. The article stopper 24 is provided so as to project onto the bottom plate portion 22. The article stopper 24 is provided at a position of the bottom plate portion 22 so as to avoid the recess 22e. Specifically, the article stopper 24 is provided along the Y direction on the opening side of the recess 22e with respect to the bottom. As a result, a part of the article 200 can be located above the recess 22e in a state where the article 200 is in contact with the article stopper 24. As a result, when the user takes out the article 200 from the mounting portion 21, it becomes easier to insert the hand under the article 200 by inserting the hand into the recess 22e.

The article stopper 24 is a portion of the edge portion 22a where the recess 22e is not formed, and is formed only in a portion located next to the opening. The article stopper 24 extends parallel to the edge 22b. The article stopper 24 may have a portion that is an edge of the recess 22e and is provided along a portion connecting the opening and the bottom as long as it does not reach the bottom of the recess 22e.

The height direction of the article stopper 24 is orthogonal to the main surface of the bottom plate portion 22. Here, the height direction of the article stopper 24 is the Z direction. The height of the article stopper 24 is lower than the height of the side plate portion 23. As a result, when the user puts the article 200 in and out of the mounting portion 21, the article 200 easily crosses the article stopper 24, and the article 200 can be easily taken in and out. However, the height of the article stopper 24 may be the same as or higher than the height of the side plate portion 23.

The thickness direction of the article stopper 24 is a direction orthogonal to the extending direction of the edge portion 22a. Here, the thickness direction of the article stopper 24 is the Y direction. The thickness dimension of the article stopper 24 is thicker than the thickness dimension of the side plate portion 23. Here, the portion of the tray 20 where the article stopper 24 is provided is a portion that can come into contact (collision) with the tray stopper 45 described later. At this time, since the thickness of the article stopper 24 is thicker than the thickness of the side plate portion 23, the rigidity of the portion of the tray 20 that comes into contact with the tray stopper 45 can be increased. Further, the back surface of the bottom plate portion 22 at the edge portion 22a is an inclined surface. Therefore, the edge portion 22a of the bottom plate portion 22 is thinner and less rigid than the other portions. Even in this case, the article stopper 24 increases the rigidity of the edge portion 22a of the tray 20. However, the article stopper 24 may be any as long as it can suppress the article 200 from falling off, and the thickness dimension of the article stopper 24 may be the same as or thinner than the thickness dimension of the side plate portion 23.

The hole 22h is provided to detect that the article 200 is placed on the bottom plate portion 22. The hole 22h is used for the detection sensor 60 described later. Here, the size of the article 200 (book) placed on the bottom plate portion 22 may be different. At this time, if there is only one detection sensor 60, if the size of the article 200 placed on the bottom plate portion 22 is small, a detection error may occur. Therefore, a plurality of detection sensors 60 are provided so that a detection error does not occur even when the size of the article 200 placed on the bottom plate portion 22 is small. A plurality of holes 22h are formed in order to correspond to the plurality of detection sensors 60.

Specifically, here, the upper limit of the size of the article (book) 200 placed on the bottom plate portion 22 is assumed to be about the same as the A4 size. Therefore, the bottom plate portion 22 is set to be the same as or larger than the A4 size (slightly larger here). At this time, the side plate portion 23 and the article stopper 24 provided around the bottom plate portion 22 prevent the A4 size article 200a from moving significantly on the bottom plate portion 22. As a result, the A4 size article 200a can be detected by any of the plurality of detection units.

On the other hand, the lower limit of the size of the article (book) 200 placed on the bottom plate portion 22 is assumed to be about the same as the A6 size (so-called paperback book size). Since the bottom plate portion 22 has a size corresponding to the A4 size, even if the side plate portion 23 and the article stopper 24 are provided around the bottom plate portion 22, the A6 size article 200b is predetermined on the bottom plate portion 22. It may not fit in the position. Even in this case, here, the plurality of detection sensors 60 are separately arranged so that any one of the plurality of detection sensors 60 can detect the A6 size article 200b. A hole 22h is formed at a position corresponding to the position of each detection sensor 60. The maximum size and the minimum size assumed for the articles placed on the tray 20 are not limited to the above examples.

More specifically, five holes 22h are formed in the bottom plate portion 22. Of the five holes 22h, four holes 22ha are provided at positions corresponding to the four corners of the rectangle. The hole 22ha is provided at a position where the A6 size article 200b can be detected regardless of the direction in which the A6 size article 200b is located at the corresponding corner of the bottom plate portion 22. FIG. 5 shows a case where the A6 size article 200b located at the corner of the bottom plate portion 22 is oriented vertically and a case where the article 200b is oriented horizontally. The vertical orientation means that the longitudinal direction of the article 200b is along the longitudinal direction (Y direction) of the bottom plate portion 22. The lateral orientation is a direction in which the longitudinal direction of the article 200b is orthogonal to the longitudinal direction (Y direction) of the bottom plate portion 22. The holes 22ha are provided at positions where the articles 200b located at the corners of the bottom plate portion 22 overlap each other regardless of the orientation between the vertical orientation and the horizontal orientation. For example, the shortest dimension (short side dimension) of the article (book) 200 that is expected to be placed is assumed. If the minimum size is A6 size, the shortest dimension is the short side dimension of A6 size. Focusing on the hole 22ha provided corresponding to one corner of the bottom plate portion 22, the distance between the article stopper 24 or the side plate portion 23b and the hole 22ha intersecting at the corner is set to be smaller than the shortest dimension. .. The holes 22ha provided corresponding to the other corners may be similarly set in relation to the shortest dimensions. Further, for example, in the short side direction (X direction) of the tray 20, the distance between the centers of the holes 22ha is set to be smaller than the shortest dimension.

The remaining one hole 22hb out of the five holes 22h is provided at a position located inside the rectangle connecting the four holes 22ha. The holes 22hb are provided at the intersections of the diagonal lines of the rectangle. As shown in FIG. 5, when the A6 size article 200b is placed sideways or diagonally on the bottom plate portion 22, it may not overlap with the four holes 22ha. The hole 22hb is provided at a position where the article 200b in this case can be detected. For example, the distance between the center of the hole 22hb and the center of the four holes 22ha is set to be smaller than the shortest dimension. Further, for example, the distance between the side plate portions 23c or 23d provided at both ends in the width direction (X direction) of the tray 20 and the center of the hole 22hb is set to be smaller than the shortest dimension.

The receiving portion 25 is a portion that receives a force from the transport mechanism 70 when the tray 20 is transferred between the storage portion 30 or the handling port 40h and the transport mechanism 70. The receiving portion 25 has a receiving surface 25a and a facing receiving surface 25b. The receiving surface 25a is a surface that receives the pushing force of the transport mechanism 70. The facing receiving surface 25b is a surface that receives the pulling force of the transport mechanism 70. The receiving portion 25 is provided at a position of the edge portions 22b, 22c, 22d other than the edge portion 22a. Here, the receiving portion 25 is provided at the position of the edge portion 22b. The receiving portion 25 includes a side plate portion 23b. Further, the receiving portion 25 includes a protruding plate portion 26 and a facing plate portion 27. The protruding plate portion 26 projects in the Y direction from the outer surface of the side plate portion 23b. The facing plate portion 27 projects in the Z direction from the tip of the protruding plate portion 26. The facing plate portion 27 faces the side plate portion 23b. The outer surface of the side plate portion 23b is the receiving surface 25a. The receiving surface 25a receives a force from the transport mechanism 70 when the tray 20 is transferred from the transport mechanism 70 to the storage unit 30 or the handling port mechanism 40. The inner surface of the facing plate portion 27 facing the side plate portion 23b is the facing receiving surface 25b. The facing receiving surface 25b faces the receiving surface 25a at a distance. The facing receiving surface 25b receives a force from the transport mechanism 70 when the tray 20 is transferred from the storage unit 30 or the handling port mechanism 40 to the transport mechanism 70. The receiving portion may be provided on the bottom plate portion.

The size of the mounting portion 21 along the width direction (X direction) of the tray 20 is larger than the dimensions of the protruding plate portion 26 and the facing plate portion 27 of the receiving portion 25. Of the receiving portions 25, the protruding plate portion 26 and the facing plate portion 27 are provided in the intermediate portion of the mounting portion 21 along the width direction of the tray 20. Of the receiving portions 25, the protruding plate portion 26 and the facing plate portion 27 are not provided at both ends of the mounting portion 21 along the width direction of the tray 20. The first stopper 36 described later in the storage portion 30 can be brought into contact with the portion where the protruding plate portion 26 and the facing plate portion 27 are not provided.

The tray 20 is supported in a posture in which the tray 20 can be manually accessed from the handling port 40h to the recess 22e in a state where the tray 20 is conveyed to the handling port 40h. The tray 20 is supported in a posture in which the edge portion 22a faces the handling port 40h.

The tray 20 may be integrally molded into a shape including the mounting portion 21 and the receiving portion 25 by injection molding using a mold. Further, the tray 20 may have a configuration in which a plurality of members molded separately are united. For example, after the member including the mounting portion 21 and the member including the receiving portion 25 are integrally molded, the two members may be combined. At this time, the plurality of members may be united by a fixing part such as a screw, may be united by using a fixing structure provided for each member such as a fitting structure, or may be united by welding or the like. May be good.

The material constituting the tray 20 is not particularly limited, and resin, metal, or the like can be used. Further, the material constituting the tray 20 may be only one type or a plurality of types. Further, the material constituting the tray 20 may be only resin, only metal, or a mixture of resin and metal.

The tray 20 is not provided with a cover that covers the bottom plate portion 22. Therefore, in the height direction, the article 200 having a height of the side plate portion 23 or higher can be placed on the mounting portion 21. Of course, the tray 20 may be provided with a cover that covers the bottom plate portion 22.

A side wall 46c is provided so as to hang down from the rear of the ceiling portion 47 (the end on the positive side in the Y direction). The side wall 46c does not reach the base 43. There is an opening between the side wall 46c and the base 43. The accommodation space is a space surrounded by a base 43, side walls 46a, 46b, 46c and a ceiling portion 47. The support portion 42 is open on both sides in the Y direction. The opening on the negative side in the Y direction of the support portion 42 is the handling port 40h of the support portion 42. The opening on the positive side in the Y direction of the support portion 42 (the opening between the side wall 46c and the base 43) is an opening for transferring the tray 20 to and from the transport mechanism 70. The upper surface of the base 43 is formed flat. A handling port side guide portion 44 is provided on the base 43. A reflection portion 60b described later in the detection sensor 60 is provided on the base 43.

The handling port side guide portion 44 is provided so as to project onto the base 43. In the handling port side guide portion 44, the tray 20 transported to the handling port mechanism 40 by the transport mechanism 70 slides and moves.

The inclined surface 44Fb is inclined downward toward the transport mechanism 70. Most of the upper surface 44F is a horizontal surface 44F, except for the end where the inclined surface 44Fb is located. When the tray 20 is transferred from the transport mechanism 70 to the handling port side guide portion 44, the tray 20 is transferred to the upper surface 44F of the handling port side guide portion 44. Since the tray 20 can slide and move mainly on the horizontal surface 44F, the upper surface 44F is an example of a surface capable of guiding the tray 20 in the horizontal direction. The inclined surface 44Fb plays an auxiliary role of guiding the front end portion of the tray 20 toward the horizontal plane 44F and thereby correcting the tray 20 so as to move in the horizontal direction. A tray stopper 45 is provided at the end of the handling port side guide portion 44 on the handling port 40h side.

The tray stopper 45 projects upward to the end of the handling port side guide portion 44 on the handling port 40h side. The tray stopper 45 prevents the tray 20 on the handling port side guide portion 44 from protruding toward the handling port 40h. The tray stopper 45 is formed in an L shape and has a portion protruding sideways of the handling port side guide portion 44. The tray stopper 45 is supported by the base 43 at a portion protruding sideways of the handling port side guide portion 44. The configuration of the tray stopper 45 is not limited to that described above. For example, the tray stopper may have a configuration in which a portion supported by the base 43 is omitted.

Further, on the main surface of the support frame 52 (the surface facing the negative side in the Y direction), the detection sensor 63 is provided in the second portion 52b.

The slide support portion 53 supports the door 49 so as to be movable in the vertical direction. The slide support portion 53 includes a slide guide 54 and a slider 55. A slide guide 54 is provided for each of the two second portions 52b. The slide guide 54 is formed in a rail shape. The slide guide 54 is provided on the second portion 52b so as to extend along the Z direction. The slider 55 is provided so as to be movable along the slide guide 54. The door 49 is supported by the slider 55.

The opening / closing mechanism 56 is provided so that the slider 55 can be reciprocated. Here, the opening / closing mechanism 56 includes two gears 57, an annular chain 58, and an opening / closing drive unit 59. The two gears 57 are provided on the side surface of the support frame 52. The two gears 57 are rotatably supported around an axis along the X direction. The two gears 57 are arranged apart in the Z direction. The annular chain 58 is rotatably supported by two gears 57. The opening / closing drive unit 59 rotationally drives one of the two gears 57. The opening / closing drive unit 59 is composed of, for example, a servomotor or the like that generates a rotational driving force. One of the two sliders 55 is connected to the annular chain 58. The rotational driving force of the opening / closing drive unit 59 in both the forward and reverse directions is transmitted to one of the gears 57, whereby the annular chain 58 rotates in either the forward or reverse direction. As the annular chain 58 rotates, the slider 55 connected to the annular chain 58 is moved and driven in both directions between the open position and the closed position of the door 49. The configuration of the drive unit is not limited to the above. For example, a cylinder, a ball screw, or the like may be adopted as the opening / closing drive unit 59.

The control unit 100 drives the door 49 to open or close based on the rotation position signal from the opening / closing drive unit 59, the detection signal of the position sensor provided in the movement path of the door 49, or the like. The rotation direction, rotation amount, etc. of the unit 59 are controlled.

The door 49 may be supported by an elastic member (coil spring or the like) that can be elastically deformed in the moving direction of the door 49 (here, the Z direction). As a result, when a user's hand or the like is caught between the peripheral edge of the handling port 40h and the door 49, the elastic member is elastically deformed, so that the holding force can be weakened.

The detection sensor 60 is provided on the base 43 at a position avoiding the handling port side guide portion 44. The detection sensor 60 detects that the article 200 is placed on the tray 20 located in the handling port mechanism 40.

The light receiving and receiving unit 60a is provided on the back side of the ceiling unit 47. The reflecting portion 60b is provided on the base 43. A hole 47h for the detection sensor 60 is formed in the ceiling portion 47. The holes 47h and the reflecting portion 60b are provided at corresponding positions. Further, in a state where the tray 20 is located at a predetermined position on the support portion 42, the hole 22h of the tray 20 is located at a position corresponding to the hole 47h for the detection sensor 60 and the reflecting portion 60b.

The light emitting / receiving unit 60a includes a light emitting unit and a light receiving unit. The floodlight emits light. The light receiving unit receives the reflected light of the light. The reflecting unit 60b reflects the light. When the article 200 is placed on the tray 20, it blocks light. Therefore, it is possible to detect that the article 200 is placed on the tray 20 when the intensity of the light received by the light receiving unit is low. Here, a plurality of detection sensors 60 (five here) are provided. The presence or absence of an object (tray 20, article 200, user's hand, etc.) in the accommodation space can be detected depending on the presence or absence of shading of the detection light. For example, when even one of the plurality of detection sensors 60 has a low intensity of light received, it can detect that the article 200 is placed on the tray 20. The detection sensor 60 may be a transmissive optical sensor. In this case, it is preferable that the light emitting portion and the light receiving portion are provided so as to face the ceiling portion 47 and the base 43 so that the detection light passes through the hole 22h.

Here, a plurality of detection sensors 61 and 62 are provided.

The detection sensor 61 is provided so that the detection light is blocked by the tip of the tray 20 while the tray 20 is located at a predetermined position on the support portion 42. As a result, the detection sensor 61 detects whether or not the tray 20 is located at a predetermined position on the support portion 42.

The detection sensor 62 is provided so that the detection light is not blocked by the tray 20 when the tray 20 is located at a predetermined position on the support portion 42. The detection sensor 62a is provided so that the detection light passes above the tray stopper 45 and in front of the tray 20. The detection sensors 62b and 62c are provided so that the detection light passes above the tray 20 at the intermediate and rear positions of the tray 20. As a result, the detection sensor 62 detects whether or not the user's hand or the article 200 or the like is located in the accommodation space.

The detection sensor 63 is provided on the support frame 52. The detection sensor 63 detects whether or not there is an object on the movement locus of the end portion of the door 49 in the handling port 40h. As a result, the detection sensor 63 can prevent the user's hand or the like that has been in the handling port 40h from being pinched between the door 49 and the peripheral edge of the handling port 40h when the door 49 is closed. For example, the detection sensor 63 includes a light emitting unit and a light receiving unit. The light projecting unit is provided on one of the second portions 52b. The light receiving portion is provided on the other side of the second portion 52b.

The reading unit 64 is provided so as to be able to read the identification information of the article 200 located in the handling port mechanism 40. For example, the reading unit 64 reads the identification tag provided on the article 200. The identification tag is not particularly limited, and various identification tags can be adopted. For example, the identification tag is one that magnetically records its own identification code (magnetic bar code, etc.), or one that records data in the form of a one-dimensional or two-dimensional figure (bar code or QR code (registered trademark), etc.). May be adopted. The identification tag may be an RFID (Radio Frequency Identifier) tag or the like. As the reading unit 64, one conforming to the identification tag is used. The identification tag and the reading device are preferably those that can be read in a non-contact manner. For example, when the article 200 is returned, the reading unit 64 reads whether the article 200 belongs to the article automatic handling device 10. The reading unit 64 is provided on the back side of the ceiling unit 47.

A door stopper 65 is provided on the first portion 52a on the main surface of the support frame 52 (the surface facing the negative side in the Y direction). When the door 49 moves so as to be in the closed state, the door stopper 65 suppresses excessive movement. In addition, a notification unit may be provided on the first portion 52a on the main surface of the support frame 52 (the surface facing the negative side in the Y direction). The notification unit notifies the user of the opening / closing of the door 49 by light or sound.

Then, the tray 20 on the outside of the pair of slide mounting portions 83 slides on the pair of transfer unit side guide portions 83a while being restricted in the width direction by the pair of side guide portions 83b. Then, it is supported in a mounting shape between the pair of slide mounting portions 83. On the contrary, the tray 20 supported in a mounting manner between the pair of slide mounting portions 83 is restricted in the width direction by the pair of side guide portions 83b, and the pair of transfer unit side guide portions 83a. It slides on and moves outward between the pair of slide mounting portions 83.

The pushing / pulling action portion 86 is configured so that the tray 20 can be pulled in or pushed out between the pair of slide mounting portions 83 and the outside.

That is, the pushing-pulling action unit 86 includes a transfer base portion 87 and an action piece 88. The transfer base portion 87 is formed in the shape of a square plate extending along the horizontal direction. An action piece 88 is formed at the end of the transfer base portion 87 on the storage portion 30 side. The working piece 88 is formed in a long plate shape that extends upward from the end of the transfer base portion 87 and extends in a direction substantially orthogonal to the extending direction of the slide mounting portion 83. The working piece 88 projects upward from the transfer unit side guide portion 83a of the slide mounting portion 83. Then, the working piece 88 is arranged to face the receiving surface of the tray 20. Here, the working piece 88 comes into contact with the receiving surface 25a in a state of being located between the receiving surface 25a and the facing receiving surface 25b. Then, the pushing / pulling action portion 86 moves toward the storage portion 30 or the support portion 42 in a state where the working piece 88 is in contact with the receiving surface 25a of the receiving portion 25 of the tray 20. As a result, the tray 20 is extruded and moves toward the storage portion 30 or the support portion 42, and the pushing action portion 86 is in contact with the facing receiving surface 25b of the receiving portion 25 of the tray 20. Moves to the slide mounting portion 83 side. As a result, the tray 20 is pulled out from the storage portion 30 or the support portion 42 and is drawn into the slide mounting portion 83. That is, the working piece 88 exerts a moving force on the tray 20. Details of these operations will be described later.

The pushing / pulling action portion 86 extends from the slide mounting portion 83 toward the storage portion 30 or the handling port mechanism 40 side along the Y direction (see the left side position in FIG. 17) and the opposite side thereof. It is movably supported from a retracted position (see the right position in FIG. 17) located closer to it.

Here, the pushing-pulling action unit 86 is movably supported by the following movable support mechanism 89.

That is, the intermediate base member 85 is attached so as to hang between the pair of horizontal frames 84 between the pair of slide mounting portions 83. The intermediate base member 85 is formed in a semi-cylindrical shape with an opening at the top. A movable support mechanism 89 is assembled to the intermediate base member 85.

The movable support mechanism 89 includes a base-side movable support portion 89a, an intermediate movable body 89b, and an action portion-side movable support portion 89c.

The base-side movable support portion 89a is provided on the bottom portion of the intermediate base member 85 along the extending direction of the slide mounting portion 83. The base-side movable support portion 89a is composed of a rail and a traveling member (for example, a linear guide) that linearly moves the rail, and movably supports the intermediate movable body 89b.

The intermediate movable body 89b has a ceiling surface. A movable support portion 89c on the action portion side is provided on the ceiling surface along the extending direction of the slide mounting portion 83.

The movable support portion 89c on the action portion side is composed of a rail and a traveling member (for example, a linear guide) that moves the rail linearly, and the push-pull action portion 86 is placed between the pair of slide mounting portions 83. It supports it so that it can move in a straight line.

Then, between the pair of slide mounting portions 83, the intermediate movable body 89b is moved to one side in the moving direction with respect to the intermediate base member 85, and the pushing / pulling action portion 86 is moved with respect to the intermediate movable body 89b in the moving direction. By moving it to one side, the pushing / pulling action unit 86 moves to the extension position. Further, between the pair of slide mounting portions 83, the intermediate movable body 89b is moved to the other side in the moving direction with respect to the intermediate base member 85, and the pushing / pulling action portion 86 is moved with respect to the intermediate movable body 89b in the moving direction. By moving it to the other side, the pushing / pulling action unit 86 moves to the retracted position.

The transfer mechanism 90 is configured to move and drive the push-pulling action unit 86, which is movably supported as described above, between the extension position and the retracted position. The transfer mechanism 90 includes a pair of gears 91, an annular chain 92, and a transfer drive unit 93.

The pair of gears 91 are rotatably supported at both end positions in the intermediate base member 85. The annular chain 92 is wound around the pair of gears 91 so as to be able to circulate and rotate. One of the linear portions of the annular chain 92 that runs upward is connected to the pushing / pulling action portion 86.

The transfer drive unit 93 is composed of a servomotor or the like that generates a rotational drive force. Here, the rotation shaft of the transfer drive unit 93 is provided at a position parallel to the rotation shaft of the gear 91. Therefore, the transfer drive unit 93 rotationally drives the gear 91 via the transmission mechanism 94. As the transmission mechanism 94, for example, an annular chain or the like spanned between a gear attached to the rotating shaft of the transfer drive unit 93 and the gear 91 can be adopted. Of course, the transfer drive unit 93 may directly rotate and drive the gear 91. The rotational driving force of the transfer drive unit 93 in both forward and reverse directions is transmitted to one of the gears 91, whereby the annular chain 92 rotates in either the forward or reverse direction. As the annular chain 92 rotates, the pushing / pulling action portion 86 connected to the annular chain 92 is moved and driven in both directions between the extension position and the retracted extension position.

In the control unit 100, the push-pull action unit 86 is moved to a predetermined position based on the rotation position signal from the transfer drive unit 93, the detection signal of the position sensor that detects the position of the push-pull action unit 86, and the like. The rotation direction, rotation amount, and the like of the transfer drive unit 93 are controlled so as to move toward and stop.

In particular, the transport mechanism 70 keeps the tray 20 supported by the support portion 42 in a state of restraining the movement of the tray 20 in the support portion 42 when the user performs at least one of the warehousing work and the warehousing work. For example, after the working piece 88 moves the tray 20 toward the support portion 42 via the receiving surface 25a, the working piece 88 is kept in contact with the receiving surface 25a to suppress the movement of the tray 20. Keep in state. The period during which the transport mechanism 70 keeps the tray 20 in the support portion 42 in a restrained state may be while the door 49 is open. The operation of suppressing the movement of the tray 20 by the transport mechanism 70 will be further described later.

<Reception Department 14>
The reception unit 14 is a portion that receives a warehousing instruction and a warehousing instruction for the automatic article handling device 10. Here, the reception unit 14 includes a touch panel device 15 having functions as a display unit and an input reception unit, and a card reader 16.

The touch panel device 15 displays various screens for accepting warehousing and delivery. For example, if the user has been reserved for shipping after the user has been identified, the goods 200 reserved for shipping are displayed and the shipping instruction is accepted. It is advisable that reservations can be accepted in advance via an internet line or the like. Further, for example, after the user is determined, a list of stored articles 200 or a search screen for the articles 200 is displayed, and an instruction of the articles 200 wishing to be delivered is received based on the display.

The card reader 16 is a device that reads a user card or the like given to each user. By reading the user card by the card reader 16, it is possible to determine whether or not the user has the right to use the equipment.

<Article information display unit 18>
The article information display unit 18 displays information about the article, for example, an article list. For example, as the article list, characters, symbols, etc. representing the stored articles may be displayed. Further, for example, an image of a stored article (for example, a cover of a book) or the like may be displayed. The article information display unit 18 may be operable by the user. The article information display unit 18 may be a touch panel display. The article information display unit 18 may be inoperable by the user. The article information display unit 18 may be a display that is not a touch panel type.

<Control unit 100>
Next, the control unit 100 will be described in detail with reference to FIG. FIG. 18 is a block diagram showing the control unit 100.

The control unit 100 controls the operation of the article automatic handling device 10. Here, the control unit 100 will be described with an example in which the control unit 100 is physically configured by one control unit, but the physically separate control units are configured to perform the processes described below in a distributed manner. May be good.

The control unit 100 is composed of a computer in which a CPU 101, a ROM 102, a RAM 103, an external storage device 104, and the like are interconnected via a bus line. The ROM 102 stores a basic program (BIOS) and the like for starting the computer, and the RAM 103 is provided as a work area when the CPU 101 performs processing according to a predetermined procedure. The external storage device 104 is composed of a non-volatile storage device such as a flash memory or a hard disk device.

The external storage device 104 stores the OS (operation system) 104a, the warehousing / delivery control program 104b, the article management data 104c, and the like.

The warehousing / delivery control program 104b defines a procedure for carrying out the transport processing of the tray 20 in the article automatic handling device 10 as described above. The warehousing / delivery processing of the tray 20 is performed by the CPU 101 as the main control unit performing arithmetic processing according to the procedure described in the warehousing / delivery control program 104b.

The article management data 104c is a table in which the specific information of the article 200 (for example, a book) is associated with the presence or absence of inventory of the article 200, each position of the in-stock article 200 in the storage unit 30, and the like. In the article management data 104c, the reservation registration, the borrower of the rented article 200, and the return deadline of the rented article 200 are set for the specific information (article name, for example, the title of the book) of the article 200 (for example, a book). It may be associated. The specific information of the article 200 is a unique identification code assigned to each article 200, and is usually the same as the identification code assigned to the identification tag provided on the article 200. By referring to the article management data 104c, it is specified at which position the identified article 200 is stored in the storage unit 30. Further, by referring to the article management data 104c, a vacant position in the storage unit 30 can be specified. The reservation registration is information indicating the presence or absence of a reservation person for each article 200. When there is a reservation person for a certain article 200, the name of the reservation person (or the identification information of the reservation person) is registered. By referring to this information, it is determined whether or not the article 200 is reserved for a certain reservation person. The borrower is a book that is out of stock, that is, information that identifies the borrower of the rented article 200 (name, identification code of the borrower, etc.). The return deadline is the return deadline of the rented article 200. The article management data 104c is generated and updated when the article 200 is loaded and unloaded.

Further, the CPU 101 is communicably connected to the transport mechanism 70, the reception unit 14, and the handling port mechanism 40 via the input / output interface 105. A command through the reception unit 14 is given to the control unit 100. The control unit 100 controls the handling port mechanism 40 and the transport mechanism 70 so as to store or discharge the article 200 based on the command through the reception unit 14 and the signals from various sensors.

The control unit 100 may be connected to an external management server via a communication interface so as to be able to communicate with each other, and the article management data 104c may be stored in the external management server. In this case, it is preferable that the user accesses the management server via the public communication network or the like through his / her own terminal device or the like, and can make a reservation for the article 200 (for example, a book) from the terminal.

<Distribution processing>
Next, the flow of the warehousing process in the article automatic handling device 10 will be described. FIG. 19 is a flowchart of the shipping process.

Next, the flow of the warehousing process in the article automatic handling device 10 will be described. FIG. 19 is a flowchart of the shipping process.

First, in step S1, the control unit 100 determines whether or not there is a delivery instruction that specifies the target of delivery based on the output from the reception unit 14. The delivery instruction that specifies the target of delivery is given by the user through the reception unit 14. The delivery instruction may be given by using the list of the stored articles 200 or the like in the reception unit 14, or may be given based on an advance reservation. If it is determined in step S1 that there is a delivery instruction, the process proceeds to the next step S2.

In step S2, the control unit 100 specifies the storage position of the article 200 to be delivered in the storage unit 30 with reference to the article management data 104c. After that, the process proceeds to step S3.

In step S3, the control unit 100 controls the transport mechanism 70 to move the transfer unit 80 toward the storage position, and further takes out the article 200 from the storage unit 30 at the storage position and moves it to the transfer unit 80. Reprint.

In the following step S4, the control unit 100 controls the transfer mechanism 70 to move the transfer unit 80 toward the handling port mechanism 40. After that, the control unit 100 controls the transport mechanism 70 to move the article 200 on the transfer unit 80 toward the support unit 42.

In the following step S5, the control unit 100 controls the transport mechanism 70 to keep the tray 20 in a state of being suppressed from moving in the support unit 42.

In the next step S6, the control unit 100 controls the handling port mechanism 40 to open the door 49. As a result, the handling port 40h is opened, and the user can access the article 200 on the tray 20 through the handling port 40h. The work of the user taking out the tray 20 or the rough article 200 is an example of the warehousing work. During this warehousing operation, the transport mechanism 70 keeps the tray 20 in a state of being restrained from moving in the support portion 42. Therefore, even if the user pushes the tray 20, the tray 20 is difficult to move to the transport mechanism 70 side.

In the next step S7, the control unit 100 determines whether or not the removal of the article 200 from the tray 20 has been completed based on the output of the detection sensor 60 and the like. If the determination result is NO, step S7 is repeated, and if the determination result is YES, the process proceeds to step S8. The end of taking out the article 200 may be made based on the output of another sensor, for example, the output of the passage detection sensor of the article at the handling port 40h. The end of taking out the article 200 may be determined by whether or not the reading unit 64 can read the article 200.

In the next step S8, the control unit 100 controls the handling port mechanism 40 to close the door 49. As a result, the handling port 40h is closed by the door 49. After the door 49 is closed, the state in which the movement of the tray 20 in the support portion 42 is suppressed (see step S5) may be released. The transport mechanism 70 may store the empty tray 20 in the support portion 42 in an empty position in the storage portion 30. The transport mechanism 70 may move the other tray 20 in the storage unit 30 to another storage position while the empty tray 20 is supported by the support unit 42.

After step S8, the process proceeds to step S9, and the control unit 100 updates the article management data 104c so that the ejected article 200 is in the warehousing situation. As the data to be updated, for example, out of the article management data 104c, the inventory of the article 200 for which delivery has been completed is updated without inventory. If necessary, the owner is recorded and the return deadline is recorded for the goods 200 that have been delivered.

This completes the shipping process.

<Receiving process>
Next, the flow of the warehousing process in the article automatic handling device 10 will be described. FIG. 20 is a flowchart of the warehousing process.

Here, a process in which the user stores the article 200 through the handling port mechanism 40 will be described.

In step S11, the control unit 100 determines whether or not there is a warehousing instruction through the reception unit 14. If it is determined that there is a warehousing instruction, the process proceeds to the next step S12.

In step S12, the control unit 100 controls the transport mechanism 70 and moves the empty tray 20 toward the support unit 42 of the handling port mechanism 40. For example, the transport mechanism 70 refers to the article management data 104c, identifies the position where the empty tray 20 is stored in the storage unit 30, takes out the empty tray 20 from the specified position, and puts it in the support unit 42. Transport toward. When the empty tray 20 is supported by the support portion 42 in advance, the transport mechanism 70 may move toward the handling port mechanism 40.

In the next step S13, the control unit 100 controls the transport mechanism 70 to keep the tray 20 in a state of being suppressed from moving in the support unit 42. For example, when the transport mechanism 70 transports the empty tray 20 to the support portion 42, the state immediately after the transport is maintained, and the working piece 88 is kept in contact with the receiving surface 25a. When the empty tray 20 is supported by the support portion 42 in advance, the transport mechanism 70 moves the working piece 88 so as to bring the working piece 88 into contact with the receiving surface 25a.

In the next step S14, the control unit 100 controls the handling port mechanism 40 to open the door 49. As a result, the handling port 40h is opened, and the user can place the article 200 on the tray 20 through the handling port 40h. The work of placing the article 200 on the tray 20 by the user is an example of the warehousing work. During this warehousing operation, the transport mechanism 70 keeps the tray 20 in a state of being restrained from moving in the support portion 42. Therefore, even if the user pushes the tray 20, the tray 20 is difficult to move to the transport mechanism 70 side.

In the next step S15, the control unit 100 determines whether or not the warehousing work of the article 200 with respect to the tray 20 has been completed based on the output of the detection sensor 60 and the like. If the determination result is NO, step S15 is repeated, and if the determination result is YES, the process proceeds to step S16. The warehousing work of the article 200 may be completed based on the output of another sensor, for example, the output of the passage detection sensor of the article at the handling port 40h. The end of the warehousing work of the article 200 may be determined by the readability of the reading unit 64.

In the next step S16, the control unit 100 reads the identification information of the article 200 by the reading unit 64.

In the next step S17, the control unit 100 controls the handling port mechanism 40 to close the door 49. As a result, the handling port 40h is closed by the door 49. After the door 49 is closed, the state in which the movement of the tray 20 in the support portion 42 is suppressed (see step S5) may be released.

After step S7, the process proceeds to step S18, and the control unit 100 identifies a vacant position in the storage unit 30 based on the article management data 104c.

In the next step S19, the control unit 100 controls the transport mechanism 70 to take the tray 20 on the support unit 42 into the transfer unit 80, move the transfer unit 80 toward an empty position, and further transfer the tray 20. The tray 20 placed on the unit 80 is stored in an empty position.

After that, in step S20, the control unit 100 updates the article management data 104c so that the article 200 stored in the vacant position of the storage unit 30 is stored in the place where the vacant position was. ..

This completes the warehousing process.

The warehousing process does not need to be performed through the handling port mechanism 40. For example, the warehousing work may be performed through the opening / closing part or the door described above. In this case, a part of the storage unit 30 is assigned as a temporary storage unit for the warehousing work, and the warehousing worker may store the article 200 in the temporary storage unit. In this case, the control unit 100 transfers the article 200 from the temporary storage unit to another storage unit through the transport mechanism 70 and stores the article 200 in an empty position while reading the identification information of the article 200, and obtains the identification information of the article 200. It may be managed in association with the storage position. The identification information of the article 200 may be read by a reading unit provided in the transfer unit 80. The reading of the identification information of the article 200 may be made so that the article 200 is stored in the storage unit 30 via the support unit 42 and is performed by the reading unit 64 in the support unit 42. Further, the operator may store the article 200 in the storage unit 30 while reading the identification information of the article 200 with a portable reading device or the like. In this case, an identification tag such as a barcode is attached to each storage position in the storage unit 30, so that the operator performs the storage work of the article 200 while associating the identification information of the article 200 with the identification information of the storage position. May be good.

<Operation>
Next, the specific operation of each part in the article automatic handling device 10 will be described.

<Transporting operation of the tray 20 between the storage unit 30 and the handling port mechanism 40>
First, the operation of transporting the tray 20 between the storage unit 30 and the handling port mechanism 40 will be described. Here, the operation in which the tray 20 is conveyed from the storage unit 30 to the handling port mechanism 40 will be described with reference to FIGS. 21 to 26. 21 to 24 are explanatory views showing how the tray 20 stored in the storage unit 30 is transferred to the transport mechanism 70. 25 and 26 are explanatory views showing how the tray 20 is transferred from the transport mechanism 70 to the handling port mechanism 40. In FIGS. 21 to 26, each component is simplified or exaggerated for convenience of explanation.

<Transfer operation of tray 20 from tray storage to transfer mechanism 70>
First, the operation of transferring the tray 20 from the tray storage unit to the transport mechanism 70 will be described with reference to FIGS. 21 to 24.

Under the control of the control unit 100, the transfer unit 80 performs the transfer operation of the tray 20 in cooperation with the operations of the traveling mechanism 71 and the elevating mechanism 76.

First, as shown in FIG. 21, it is assumed that the tray 20 is stored in the tray storage portion in a mounted manner. The tray 20 is placed in the tray storage portion with the receiving portion 25 facing the transport mechanism 70. In this state, the first stopper 36, which is an example of the drop-out suppressing stopper, faces the tray 20 from the transport mechanism 70 side. Therefore, the tray 20 is prevented from falling off to the transport mechanism 70 side. Then, the transfer unit 80 is moved to a position facing the tray storage portion by driving the traveling mechanism 71 and the elevating mechanism 76. In the initial facing state, the transfer unit side guide portion 83a of the pair of slide mounting portions 83 is below the support surface of the storage side guide portion 35 of the tray storage portion (action from the transfer unit side guide portion 83a). It is at a height (downward by a dimension larger than the protruding dimension of the piece 88).

In the above state, as shown in FIG. 22, the pushing / pulling action portion 86 moves toward the extension position on the tray storage portion side by driving the transfer mechanism 90. Then, the working piece 88 moves beyond the facing plate portion 27 to the mounting portion 21 side.

After that, as shown in FIG. 23, the entire transfer unit 80 is raised by driving the elevating mechanism 76. Then, the working piece 88 is located between the facing plate portion 27 and the side plate portion 23b. At this time, the storage unit 30 is provided with a first stopper 36 that presses the rear portion of the tray 20. Therefore, the elevating mechanism 76 is equal to or higher than the height of the first stopper 36 and lifts the rear portion of the tray 20. That is, the working piece 88 pushes the protruding plate portion 26 from below and lifts it upward. On the side opposite to the transport mechanism 70 with respect to the storage unit 30, there is a panel or the like constituting the housing 12. Therefore, the movement of the article 200 from the tray 20 to the side opposite to the transport mechanism 70 is suppressed by the housing 12 or the like. Further, here, the tray 20 is provided with the article stopper 24, and the tray storage portion is provided with the second stopper 37. Therefore, the movement of the article 200 from the tray 20 to the side opposite to the transport mechanism 70 is also suppressed by the article stopper 24 and the second stopper 37. Further, the movement of the tray 20 from the tray storage portion to the side opposite to the transport mechanism 70 is suppressed by the housing 12, the second stopper 37, and the like.

After that, as shown in FIG. 24, the pushing / pulling action unit 86 moves toward the retracted position by driving the transfer mechanism 90. Then, the working piece 88 comes into contact with the facing receiving surface 25b of the facing plate portion 27, and the tray 20 is pulled onto the pair of slide mounting portions 83 so as to slide on the pair of slide mounting portions 83, and the tray is stored. The transfer operation from the unit to the transfer unit 80 is completed.

It is preferable that the pushing / pulling action portion 86 is lowered so that the entire longitudinal direction of the pair of slide mounting portions 83 comes into contact with the lower surface of the tray 20 at the timing after the rear portion of the tray 20 has passed over the first stopper. .. The lowering timing of the pushing / pulling action unit 86 may be during the movement of the pushing / pulling action section 86 in the direction along the Y direction, or may be in a state of being stopped at a retracted position or the like. Even when the pushing / pulling action portion 86 is lowered, the working piece 88 is located between the receiving surface 25a and the facing receiving surface 25b, and can come into contact with the receiving surface 25a or the facing receiving surface 25b by moving in the Y direction. It is preferable to keep it at.

The operation of transferring the tray 20 from the transport mechanism 70 to the tray storage unit may be performed by operating in the reverse manner of the above-mentioned transfer operation. However, since the working piece 88 moves in the opposite direction to the above, the working piece 88 pushes the tray 20 from the transport mechanism 70 toward the tray storage portion and moves the tray 20 in a state of being in contact with the receiving surface 25a.

The tray storage portion is provided with a first stopper 36 that presses the rear portion of the tray 20. However, since the first stopper 36 is provided with an inclined surface, it is not necessary to lift the tray 20 when the tray 20 is transferred from the transport mechanism 70 to the tray storage portion, and as will be described later, The tray 20 can be pushed in and transferred in the same manner as when the tray 20 is transferred from the transport mechanism 70 to the handling port mechanism 40.

<Transfer operation of tray 20 from transfer mechanism 70 to handling port mechanism 40>
Next, the operation of transferring the tray 20 from the transport mechanism 70 to the handling port mechanism 40 will be described with reference to FIGS. 25 and 26.

When the tray 20 is transferred from the storage unit 30 to the transport mechanism 70, as shown in FIG. 24, the working piece 88 of the pushing / pulling action unit 86 is located between the facing plate portion 27 and the side plate portion 23b. , The tray 20 is placed on the slide mounting portion 83. In this state, the transfer unit 80 is moved to a position facing the handling port mechanism 40 as shown in FIG. 25 by driving the traveling mechanism 71 and the elevating mechanism 76. In the initial facing state, the transfer unit side guide portion 83a of the pair of slide mounting portions 83 is at the same height as the support surface of the handling port side guide portion 44.

In the above state, as shown in FIG. 26, the pushing / pulling action unit 86 moves toward the extension position by driving the transfer mechanism 90. Then, the working piece 88 comes into contact with the receiving surface 25a, which is the outer surface of the side plate portion 23b, and is moved so as to push the tray 20. Then, the tray 20 moves along the horizontal direction so as to slide on the pair of slide mounting portions 83, and is pushed to a predetermined position by the support portion 42 in the handling port mechanism 40.

The predetermined position may be a position where the tray 20 and the tray stopper 45 come into contact with each other, or may be a position before the tray 20 comes into contact with the tray stopper 45. When the predetermined position is the position where the tray 20 and the tray stopper 45 come into contact with each other, it is preferable that the elastic member is connected to the working piece 88. The elastic member can be elastically deformed in the pushing direction (here, the Y direction). When the tray 20 and the tray stopper 45 come into contact with each other while the working piece 88 is moving toward the extension position, the elastic member is elastically deformed, and further movement of the working piece 88 is suppressed. As a result, it is possible to prevent the tray 20 from being subjected to a strong pushing force.

As described above, the transfer operation of the tray 20 from the transfer unit 80 to the handling port mechanism 40 is completed. The tray 20 is supported in a posture in which the recess 22e can be accessed from the handling port 40h in a state where the tray 20 is conveyed to the handling port 40h. In this state, the working piece 88 keeps in contact with the receiving surface 25a. Therefore, even if the tray 20 is pushed toward the transport mechanism 70, it is difficult to move to the transport mechanism 70 side.

The operation of transporting the tray 20 from the handling port mechanism 40 to the tray storage unit can also be performed in the same manner as described above by using the pushing / pulling action unit 86. However, the handling port mechanism 40 is not provided with a stopper for pressing the rear portion of the tray 20. Therefore, when the tray 20 is transferred from the handling port mechanism 40 to the transport mechanism 70, the operation of lifting the rear portion of the tray 20 can be omitted.

<Handling operation of the article 200 at the handling port 40h>
Next, the handling operation of the article 200 will be described. Here, the operation in which the article 200 is handled while the tray 20 is located in the handling port mechanism 40 will be described with reference to FIG. 27. FIG. 27 is a schematic cross-sectional view showing how the article 200 is handled while the tray 20 is located at the handling port mechanism 40.

As shown in FIG. 26, when the tray 20 is conveyed to the handling port mechanism 40, the door opening / closing portion 50 opens the door 49. After the door 49 is opened, the user performs at least one of the warehousing work and the warehousing work on the tray 20. At this time, when the tray 20 is located at the handling port mechanism 40 and the door 49 is open, the working piece 88 is kept positioned at the receiving portion 25 as shown in FIG. 27. In particular, here, the working piece 88 is kept in contact with the receiving surface 25a. As a result, the movement of the tray 20 (particularly the movement in the Y direction) is suppressed, and the posture of the tray 20 is stabilized. At this time, the tray 20 may be pressed toward the tray stopper 45 by the working piece 88. For example, the tray 20 may be in a state of being pressed toward the tray stopper 45 by the working piece 88 by the working piece 88 resting at a position where the tray 20 comes into contact with the tray stopper 45. Further, for example, when the elastic member is connected to the working piece 88, the elastic member may be elastically deformed and the restoring force may press the tray 20 toward the tray stopper 45. Of course, the tray 20 does not have to be pressed toward the tray stopper 45 by the working piece 88.

When the door 49 is opened, the user takes out the article 200 placed on the bottom plate portion 22. At this time, the user can grasp the article 200 placed on the bottom plate portion 22 by using the recess 22e. Here, if the size of the article 200 is large, the weight of the article 200 may be large, or the gap between the article 200 and the side plate portion 23 may be narrow, making it difficult for the user to grasp the article 200. Even in this case, the user can use the recess 22e to grab the article 200 placed on the bottom plate portion 22. Therefore, even if the size of the article 200 is large, the user can easily grasp the article 200. Even if the size of the article 200 is small, the user may grab the article 200 by using the recess 22e.

Specifically, when the size of the article 200 placed on the tray 20 is large, a part of the article 200 overlaps the recess 22e regardless of the position of the article 200 on the bottom plate portion 22. Therefore, as shown in FIG. 27, the user can directly insert the hand UH into the recess 22e to support the bottom surface of the article 200. Here, since the tray 20 is placed on the handling port side guide portion 44, the distance between the base 43 and the article 200 becomes large. Therefore, the user can easily insert the hand UH below the article 200.

When the size of the article 200 placed on the tray 20 is small, the area where the article 200 can move on the bottom plate portion 22 becomes large, and the tray 20 on which the article 200 is placed is placed in the handling port mechanism 40. In the initial state of being transported, the article 200 may be located at a position where it does not overlap the recess 22e. Even in this case, the user can arrange the article 200 so as to overlap the recess 22e by moving the article 200 toward the edge portion 22a by hand UH. Thereby, even if the size of the article 200 is small, the user can grasp the article 200 placed on the bottom plate portion 22 by using the recess 22e.

Further, when the user places the article 200 on the empty tray 20, the user may place the article 200 on the recess 22e.

<Effects, etc.>
According to the tray 20 configured as described above and the article automatic handling device 10 provided with the tray 20, since the recess 22e is formed in the edge portion 22a of the bottom plate portion 22 in the tray 20, the article placed on the bottom plate portion 22. When grabbing the 200, the user can put his hand UH in the recess 22e. This makes it easier for the user to grasp the article 200 placed on the bottom plate portion 22.

Further, the article stopper 24 prevents the article 200 placed on the bottom plate portion 22 from falling from the edge portion 22a.

Further, since a plurality of holes 22h for detecting that the article 200 is placed on the bottom plate portion 22 are formed, the article 200 is placed on the bottom plate portion 22 even when the article 200 is smaller than the bottom plate portion 22. It will be easier to reliably detect that it has been done. Further, the plurality of detection sensors 60 are arranged so that the lower limit size article 200 can be detected at any position on the bottom plate portion 22. Therefore, it is easy to detect the article 200. Further, for example, when the article 200 is placed on the bottom plate portion 22 by the user, any detection sensor 60 can detect the article 200 regardless of the position on which the article 200 is placed. Therefore, the warehousing operation by the user becomes simple.

Further, in the handling port 40h, since the detection sensor 60 is provided at a position avoiding the handling port side guide portion 44, when the tray 20 is taken in and out of the handling port mechanism 40, the detection sensor 60 and the bottom plate portion 22 are used. Is suppressed from contacting.

Further, the tray stopper 45 can prevent the tray 20 from protruding toward the handling port 40h.
