By the way, in a technical field such as Patent Document 1, there is already known an article storage shelf capable of storing a plurality of articles arranged side by side in the depth direction of the storage section. In such an article storage shelf as well, it is preferable that positional deviation in the depth direction can be regulated for each of a plurality of articles stored side by side in the depth direction. In order to achieve this, for example, the stopper (stopper 13a) disclosed in Patent Document 1 may be provided between a plurality of articles arranged in the depth direction and stored in the storage unit in the depth direction. Conceivable. This makes it possible to regulate the positional deviation of each of the plurality of articles in the depth direction. However, in this case, when the article is put in and taken out by sliding the placing surface of the storage section, the movement of the article in the depth direction is restricted by the stopper. It becomes difficult to take items in and out of the

In view of the above-mentioned actual situation, there is provided an article storage that is capable of restricting the positional deviation of articles stored in a storage section in the depth direction, and that allows the article to be taken in and out by sliding along the mounting surface of the storage section along the depth direction. Realization of the shelf is desired.

The article storage shelf according to the present disclosure is
a storage unit having a placement surface on which an article is placed, and storing a plurality of the articles lined up in the depth direction to be taken in and out by sliding on the placement surface along the depth direction;
a regulating protrusion that is formed to protrude upward from the placement surface and that regulates movement of the article stored in the storage section in the storage section;
The front side in the depth direction is the front side in the depth direction, and the back side in the depth direction is the back side in the depth direction,
The storage unit is
a first placement area that is an area of the placement surface on which a first article that is the first article is placed;
a second placement area that is set apart from the first placement area on the depth side in the depth direction and that is an area of the placement surface on which a second article that is the second article is placed; ,
a regulation area that is set between the first placement area and the second placement area and is an area of the placement surface on which the regulation projection is arranged;
The regulation protrusion is
Formed at a first boundary portion that is a boundary portion between the regulation region and the first placement region in the article sliding region that overlaps the sliding trajectory of the article that slides along the depth direction. a first protrusion;
a second protrusion formed in a second boundary portion that is a boundary portion between the article sliding region and the second placement region in the regulation region;
The first projection has a first inclined surface that is inclined upward from the front side in the depth direction toward the back side in the depth direction,
The second projection has a second inclined surface that is inclined upward from the back side in the depth direction toward the front side in the depth direction.

According to this configuration, in the restricted area set between the first placement area where the first article is placed and the second placement area where the second article is placed, the Since the regulating protrusion is formed to protrude, the first article is prevented from moving backward in the depth direction by a certain amount or more due to vibration of the placement surface, and the second article is moved forward in the depth direction by a certain amount or more. can be regulated. Therefore, according to this configuration, it is possible to prevent the articles stored in the storage section from being displaced in the depth direction due to, for example, vibration of the article storage shelf. Also, the restriction protrusion includes a first protrusion formed at a first boundary portion of the restriction area and a second protrusion formed at a second boundary portion of the restriction area. Therefore, it is possible to prevent the first article from crossing the boundary of the first placement area and moving toward the restricted area, and the second article from crossing the boundary of the second placement area and moving toward the restricted area. can be regulated. Therefore, it is possible to keep the position of the article stored in the storage section in the depth direction within an appropriate range. Furthermore, according to this configuration, since the first protrusion has the first inclined surface and the second protrusion has the second inclined surface, when an article is taken in and out of the storage section in the depth direction, An article moving backward in the depth direction can easily ride on the first projection by the first inclined surface, and an article moving to the near side in the depth direction can easily ride on the second projection by the second inclined surface. Therefore, it is possible to easily move an article between the first placement area and the second placement area for loading and unloading of the article. Therefore, according to this configuration, it is possible to regulate the positional deviation of the article stored in the storage section in the depth direction, and to slide the article on the mounting surface of the storage section along the depth direction so that the article can be taken in and out. An article storage shelf is realized.

[Goods]
Here, an article 90 to be transported by the transport device 2 (to be transferred by the transfer mechanism 21) and to be stored by the storage unit 13 will be described. In the following description of the article 90 , any “direction” or any “side” is defined based on the state in which the article 90 is stored in the storage section 13 .

In this embodiment, the article 90 is a container for storing products or the like. More specifically, the article 90 is a resin container (for example, a container or a collapsible so-called collapsible container).

As shown in FIGS. 4 to 6, the article 90 includes a main body portion 900 and a bottom portion 904 formed to protrude downward from the main body portion 900. As shown in FIGS. In this embodiment, the body part 900 is a part in which products and the like are accommodated, and is formed in a box shape. The body portion 900 has a front surface portion 901 formed on the front surface facing the front side X1 in the depth direction and a rear surface facing the back side X2 in the depth direction in a state where the article 90 is stored in the storage portion 13. It has a surface portion 902 and side surface portions 903 formed on both side surfaces facing in the width direction Y, respectively. The pair of side portions 903 face opposite sides in the width direction Y to each other. Note that the front surface portion 901 and the rear surface portion 902 have the same structure, and both can be the front surface portion 901 or the rear surface portion 902 depending on the storage state of the article 90 .

The bottom portion 904 is a portion that is placed on the placement surface 13</b>F of the storage portion 13 when the article 90 is stored in the storage portion 13 . As described above, the bottom portion 904 is formed to protrude downward from the body portion 900 . In this embodiment, the bottom portion 904 is smaller than the body portion 900 in plan view. More specifically, in plan view, the outer edge of the bottom portion 904 is arranged closer to the center of gravity of the article 90 than the outer edge of the main body portion 900 . That is, in this example, the front end portion of the bottom portion 904 is arranged on the far side X2 in the depth direction from the front portion 901 . A rear end portion of the bottom portion 904 is arranged on the front side X1 in the depth direction from the rear surface portion 902 . Both ends of the bottom portion 904 in the width direction Y are arranged closer to the center in the width direction Y than the side portions 903 arranged on the same side in the width direction Y among the pair of side portions 903 .

Since the article 90 has such a configuration, the body portion 900 protrudes in both the depth direction X and the width direction Y with respect to the bottom portion 904 . Therefore, the body portion 900 has a body portion lower surface 900f facing downward at an outer edge portion that does not overlap with the bottom portion 904 in plan view. The lower surface 900f of the main body and the placement surface 13F face each other in the vertical direction Z when the article 90 is stored in the storage unit 13 .

[Configuration of article storage shelf]
As shown in FIGS. 4 to 6, the article storage shelf 1 has a placement surface 13F on which an article 90 is placed, and is slid on the placement surface 13F along the depth direction X to be taken in and out. A storage part 13 for storing a plurality of articles 90 arranged in the depth direction X is provided. In this example, the storage unit 13 includes a plurality of shelf board members 130 arranged in the width direction Y. As shown in FIG. The mounting surface 13</b>F of the storage section 13 is formed by the upper surfaces of the plurality of shelf board members 130 provided in the storage section 13 . In addition, in this example, one storage section 13 is configured to be able to store two articles 90 side by side in the depth direction X. As shown in FIG. However, the present invention is not limited to this, and one storage unit 13 may be configured to store three or more articles 90 side by side in the depth direction X.

Here, the articles 90 stored in the storage section 13 may be displaced within the storage section 13 due to vibration of the article storage shelf 1 or the like. In particular, in this embodiment, the storage unit 13 is installed adjacent to the conveying device 2 that conveys the articles 90 . More specifically, a travel rail 2R for travel of the travel carriage 20 of the conveying device 2 is provided integrally with the beam 12 constituting the article storage shelf 1 (see FIG. 1). Therefore, the article storage shelf 1 may vibrate due to the operation of the transport device 2 . When the article storage shelf 1 vibrates in this way, the articles 90 stored in the storage section 13 may slide on the placement surface 13F and be displaced due to the vibration. The misalignment of the article 90 can hinder proper transfer of the article 90 by the transfer mechanism 21 of the conveying device 2 (for example, receiving operation).

Therefore, the article storage shelf 1 according to the present disclosure is formed to protrude upward from the placement surface 13F, and is a regulating projection that regulates the movement of the articles 90 stored in the storage section 13 within the storage section 13. 15. Since the regulation protrusion 15 protrudes upward from the placement surface 13F on which the article 90 is placed, when the article 90 stored in the storage section 13 attempts to move from its proper position, the regulation protrusion 15 is prevented from moving. It contacts the article 90 and regulates the movement of the article 90 . As a result, it is possible to prevent the article 90 stored in the storage section 13 from being displaced from the appropriate position due to the vibration of the article storage shelf 1 .

In this embodiment, the restricting protrusion 15 is formed integrally with the shelf member 130 . According to this configuration, the restricting protrusion 15 can be easily formed by a method such as press molding. In this embodiment, at the same time as or before or after the process of forming the shelf plate member 130 by bending a plurality of portions of a flat plate-like member, the regulating protrusions 15 are formed by press-molding the specified portions. forming. However, not limited to this, the restricting protrusion 15 may be configured by a member separate from the shelf member 130 and may be arranged in the storage section 13 by being attached to the shelf member 130 .

As shown in FIGS. 5 and 6, the storage unit 13 includes a first placement area A1, which is an area of a placement surface 13F on which a first article 91, which is the first article 90, is placed, and a first placement area A1. a second placement area A2, which is an area of the placement surface 13F on which the second article 92, which is the second article 90, is placed and which is set apart from the placement area A1 on the depth direction back side X2; A regulation area AR is set between the first mounting area A1 and the second mounting area A2 and is an area of the mounting surface 13F on which the regulation protrusion 15 is arranged.

Below, the article 90 placed on the first placement area A1 or the article 90 to be placed on the first placement area A1 is defined as a first article 91. FIG. Also, the article 90 placed on the second placement area A2 or the article 90 to be placed on the second placement area A2 is defined as a second article 92 . That is, the article 90 being transferred to the first placing area A1 is also referred to as the first article 91 here. The same applies to the second article 92 as well. Also, the main body, the front surface, the rear surface, the side surface, and the bottom of the first article 91 are denoted by reference numerals 910, 911, 912, 913, and 914 in this figure. Similarly, the body, front, rear, side and bottom portions of the second article 92 are denoted by 920, 921, 922, 923 and 924 in this figure. Note that the first article 91 and the second article 92 are simply referred to as an article 90 when not particularly distinguished.

When the article 90 is transferred by the transfer mechanism 21, if the article sliding region overlaps the sliding trajectory of the article 90 sliding along the depth direction X, as shown in FIG. A part or the whole is set so as to overlap with the article sliding area in plan view.

As shown in FIGS. 5 and 7, the regulation protrusion 15 is formed in a first boundary portion B1, which is a boundary portion between the article sliding region and the first placement region A1 in the regulation region AR. A first protrusion 151 and a second protrusion 152 formed in a second boundary portion B2 which is a boundary portion between the article sliding area and the second placement area A2 in the regulation area AR. ing. As a result, the first article 91 crosses the boundary of the first placement area A1 and moves toward the regulation area AR, and the second article 92 crosses the boundary of the second placement area A2 and moves toward the regulation area AR. can be restricted from moving to the side of Therefore, it is possible to keep the position of the article 90 stored in the storage section 13 in the depth direction X within an appropriate range.

As shown in FIG. 5, in the present embodiment, the article storage shelf 1 is further arranged at both ends of the storage section 13 in the width direction Y so that the articles 90 stored in the storage section 13 are located at the width direction Y position. and a width direction restricting portion 14y that restricts the movement of the article 90 stored in the storage portion 13 to the depth direction back side X2 beyond the storage portion 13. and a depth direction regulating portion 14x for regulating the position of the article 90 in the depth direction X so that it does not move. As a result, the misalignment in the width direction Y of the article 90 stored in the storage section 13 and the depth of the article 90 (here, the second article 92 stored on the depth side X2 in the depth direction) stored in the storage section 13 Positional deviation to the back side X2 in the direction can be regulated.

In this embodiment, when an article 90 is stored in the storage section 13 , the width direction restricting sections 14 y are arranged on both sides in the width direction Y with respect to the article 90 . In this example, the width direction restricting portions 14y are arranged on both sides in the width direction Y with respect to the first placement area A1. In the illustrated example, a pair of width direction restricting portions 14y are arranged spaced apart in the depth direction X on both sides in the width direction Y with respect to the first placement area A1. That is, four width direction restricting portions 14y are arranged for one first placement area A1. As a result, it is possible to prevent the first article 91 from rotating around the axis orthogonal to the mounting surface 13F, and it becomes easy to regulate the posture of the first article 91 to a proper posture. In other words, the posture of the first article 91 is regulated such that the side surface portion 913 of the first article 91 is along the depth direction X and the front surface portion 911 and rear surface portion 912 of the first article 91 are along the width direction Y. can do. Therefore, a configuration is realized in which the first article 91 can be easily transferred in an appropriate posture. In this example, in order to enhance such a regulating function, each of the width direction regulating portions 14y is positioned outside the first placement area A1 and adjacent to the boundary in the width direction Y of the first placement area A1. It is placed in a position where Further, the width direction restricting portion 14y is arranged in the second placement area A2 in the same manner as in the case of the first placement area A1. That is, in this example, four width direction restricting portions 14y are arranged for one second placement area A2. Therefore, a configuration is realized in which the second article 92 can be easily transferred in an appropriate posture.

In this embodiment, the depth direction restricting portion 14x is arranged on the depth direction depth side X2 with respect to the second article 92 placed in the second placing area A2. In this example, the depth direction restricting portion 14x is arranged on the depth direction depth side X2 with respect to the second placement area A2. More specifically, the depth direction restricting portion 14x is arranged outside the second placement area A2 and adjacent to the boundary of the second placement area A2 on the depth direction back side X2. In the illustrated example, one depth direction restricting portion 14x is arranged on the depth direction depth side X2 with respect to the second placement area A2. However, the present invention is not limited to this, and a plurality of depth direction restricting portions 14x may be arranged on the depth direction depth side X2 of the second placement area A2.

In this embodiment, each of the width direction regulation portion 14y and the depth direction regulation portion 14x is configured by a member separate from the shelf member 130, and is arranged in the storage portion 13 by being attached to the shelf member 130. ing. However, not limited to this, at least one of the width direction regulation portion 14 y and the depth direction regulation portion 14 x may be configured integrally with the shelf member 130 .

As described above, according to the article storage shelf 1 according to the present embodiment, even if the article storage shelf 1 vibrates due to the operation of the conveying device 2, for example, the articles 90 stored in the storage section 13 remain within the appropriate range. can be restricted from moving in the depth direction X and width direction Y beyond.

Here, as described above, the conveying device 2 slides the article 90 along the depth direction X on the placement surface 13F of the storage section 13, so that the article 90 is taken in and out of the storage section 13 ( transfer). The restricting protrusion 15 is arranged in an article sliding area that overlaps the sliding locus of the article 90 that slides along the depth direction X when the article 90 is transferred by the conveying device 2 . . Therefore, the restricting protrusion 15 must not restrict the movement of the article 90 in the depth direction X by the conveying device 2 . That is, even in the configuration in which the restricting protrusion 15 is provided between the first placement area A1 and the second placement area A2 in the depth direction X, the article 90 is positioned between the two areas A1 and A2. Movement in the depth direction X must be allowed.

Therefore, as shown in FIGS. 7 and 8, the first projection 151 of the restricting projection 15 has a first inclined surface 151F that is inclined upward from the front side X1 in the depth direction toward the back side X2 in the depth direction. , and the second protrusion 152 of the restricting protrusion 15 has a second inclined surface 152F that is inclined upward from the depth direction back side X2 toward the depth direction front side X1. With this configuration, when an article 90 is taken in and out of the storage section 13 in the depth direction X, as shown in FIG. The surface 151F makes it easy to ride on the first protrusion 151 . In addition, as shown in FIG. 11, the article 90 moving from the second placement area A2 to the front side X1 in the depth direction can easily ride on the second projecting portion 152 due to the second inclined surface 152F. Therefore, it is possible to easily move the article 90 between the first placement area A1 and the second placement area A2 in order to put the article 90 in and out. Therefore, according to this configuration, when the article storage shelf 1 vibrates, it is possible to prevent the articles 90 stored in the storage section 13 from moving in the depth direction X beyond the proper position, and When the article 90 is transferred by , the movement of the article 90 in the depth direction X can be allowed between the first placement area A1 and the second placement area A2.

As shown in FIG. 8, in the present embodiment, the first upper end point 151t, which is the upper end of the first inclined surface 151F, is located on the depth direction depth side X2 from the first lower end point 151u, which is the lower end of the first inclined surface 151F. A first inclined surface 151F is formed so as to be positioned. In addition, the second inclined surface 152F is arranged so that the second upper end point 152t, which is the upper end of the second inclined surface 152F, is positioned closer to the front side X1 in the depth direction than the second lower end point 152u, which is the lower end of the second inclined surface 152F. is formed. In this example, the first lower end point 151u of the first inclined surface 151F and the second lower end point 152u of the second inclined surface 152F are arranged at the same height. A first upper end point 151t of the first inclined surface 151F and a second upper end point 152t of the second inclined surface 152F are arranged at the same height. Furthermore, in this example, the first inclined surface 151F and the second inclined surface 152F are shaped to be mirror-symmetrical to each other in the width direction Y view.

As shown in FIGS. 7 and 8, in the present embodiment, the restricting protrusion 15 protrudes upward from the mounting surface 13F and extends along the depth direction X to form a first protrusion 151 and a second protrusion 152. It further includes an intermediate protrusion 150 formed to connect and is formed to be continuous along the depth direction X. As shown in FIG. This makes it possible to slide the article 90 in the depth direction X in the regulation area AR, compared to the case where the regulation projection 15 does not include the intermediate projection 150 and the first projection 151 and the second projection 152 are separated. When the article 90 moves over the regulation projection 15, the number of vertical movements can be reduced. In addition, if the restricting protrusion 15 is configured as described above, even if the bottom portion 904 of the article 90 has an uneven shape, for example, grid-like ribs are formed on the bottom portion 904 of the article 90, the article 90 can be is slid in the depth direction X in the restricted area AR, the vertical movement of the article 90 can be suppressed.

In this embodiment, the upper end of the intermediate protrusion 150, the first upper end point 151t and the second upper end point 152t are arranged at the same height. That is, the portion of the restricting protrusion 15 extending from the first upper end point 151t to the second upper end point 152t is flat. Thereby, when the article 90 is slid in the depth direction X in the regulation area AR, the article 90 can be easily slid on the regulation protrusion 15 .

In this embodiment, the height of the upward projection of the restricting projection 15 from the mounting surface 13F (hereinafter referred to as the restricting projection height 15Lz) is determined by the plate thickness 130t of the plate member constituting the shelf member 130. 0.5 to 3 times as high as Preferably, the restricting projection height 15Lz is 2 to 2.5 times the plate thickness 130t. By setting the regulating protrusion height 15Lz in this way, particularly when the regulating protrusion 15 is integrally formed with the shelf board member 130, the articles 90 stored in the storage section 13 are not unintentionally moved. It is possible to regulate the positional deviation in the depth direction X, and the intentional depth direction of the article 90 when the article 90 is slid on the mounting surface 13F of the storage part 13 along the depth direction X and taken in and out. Any configuration that allows X movement can be suitably implemented.

In this embodiment, the restricting protrusion 15 is formed in a strip shape extending along the depth direction X. As shown in FIG. In other words, a restriction projection length 15Lx, which is the length of the restriction projection 15 in the depth direction X, is longer than the restriction projection width 15Ly, which is the length of the restriction projection 15 in the width direction Y. As a result, when the article 90 is slid in the depth direction X in the regulation area AR, the size of the article 90 on the regulation protrusion 15 is suppressed while suppressing the size of the regulation protrusion 15 from becoming too large in plan view. A configuration that allows the smooth movement of the For example, the restricting protrusion width 15Ly is preferably 1/10 to 1/30 times longer than the restricting protrusion length 15Lx, more preferably 1/15 to 1/25 times longer. good.

In this embodiment, the average inclination angle θ of the first inclined surface 151F and the second inclined surface 152F in the depth direction X is within the range of 15° to 60° with respect to the mounting surface 13F. . Preferably, the inclination angle θ is within the range of 30° to 50° with respect to the mounting surface 13F. With this configuration, when the article 90 is slid in the depth direction X to be put in and taken out of the storage section 13, the article 90 can easily ride on the first protrusion 151 and the second protrusion 152. can. Here, when the first inclined surface 151F is a curved surface, the inclination angle θ is an angle obtained by averaging angles of tangent lines at successive points from the first lower end point 151u to the first upper end point 151t. The same applies to the case where the second inclined surface 152F is a curved surface. In the present embodiment, as shown in FIG. 8, the first inclined surface 151F and the second inclined surface 152F are arc-shaped curved surfaces near the upper end and near the lower end in the cross section along the depth direction X, respectively. , are connected linearly.

As shown in FIG. 5, in the present embodiment, the restricting protrusion 15 as described above extends in the width direction Y within the article sliding region overlapping the sliding trajectory of the article 90 sliding along the depth direction X. Multiple are formed side by side. With such a configuration, when the article 90 is slid in the depth direction X to be put in and taken out of the storage section 13 , the article 90 is pushed over the plurality of regulating projections 15 while the article 90 straddles the plurality of regulating projections 15 . It can be moved on the part 15 . Therefore, the article 90 can be moved along the depth direction X in a stable posture. In the illustrated example, two restricting projections 15 are spaced apart in the width direction Y for one storage portion 13 . Although illustration is omitted, three or more restricting protrusions 15 may be arranged side by side in the width direction Y for one storage portion 13 .

Further, in the present embodiment, the plurality of restricting protrusions 15 are arranged at the same position in the depth direction X with each other. More specifically, the positions of the first protrusions 151 in each of the plurality of restricting protrusions 15 are arranged at the same position in the depth direction X, and the second protrusions in each of the plurality of restricting protrusions 15 152 positions are arranged at the same position in the depth direction X with each other. As a result, for example, even if the width direction restricting portion 14y is not provided, the plurality of restricting projections 15 aligned in the width direction Y move in contact with the articles 90 stored in the storage portion 13 at a plurality of locations. Therefore, it is possible to prevent the article 90 from rotating around the axis orthogonal to the placement surface 13F due to vibration or the like.

Here, in FIG. 9, the bottom portion 914 of the first article 91 placed on the first placement area A1 is in contact with the first protrusion 151, and the second article placed on the second placement area A2 is shown. 92 shows a state in which the bottom 924 of 92 is in contact with the second projecting portion 152 (hereinafter referred to as an article approach state). This article close state is a state in which the first article 91 and the second article 92 stored in the same storage section 13 are in the closest positional relationship to each other. In the article approach state, the first article 91 touches the first lower end point 151u on the first inclined surface 151F from the front side X1 in the depth direction, and the second article 92 touches the second lower end point 152u on the second inclined surface 152F. They are in contact from the back side X2 in the direction.

As shown in FIG. 9, in the present embodiment, the distance in the depth direction X between the rear surface portion 912 of the first article 91 and the front surface portion 921 of the second article 92 facing each other in the depth direction X is As the minimum article interval Ls, the minimum article interval Ls is larger than the dimension of the locking portion 212 in the transfer mechanism 21 in the depth direction X (hereinafter referred to as locking portion length 212Lx). A distance in the depth direction X between the first protrusion 151 and the second protrusion 152 (regulating protrusion length 15Lx) is set. Here, the restriction protrusion length 15Lx is the distance in the depth direction X from the end of the first protrusion 151 on the front side X1 in the depth direction to the end of the second protrusion 152 on the back side X2 in the depth direction. In this example, the restricting protrusion length 15Lx is the distance in the depth direction X from the first lower end point 151u on the first inclined surface 151F to the second lower end point 152u on the second inclined surface 152F.

When the receiving operation of the first article 91 is performed in the article approaching state, the locking portion 212 of the transfer mechanism 21 is arranged between the first article 91 and the second article 92 in the depth direction X, and then , to the rear surface portion 912 of the first article 91 . According to the above configuration, the regulating protrusion length 15Lx is set such that the minimum product interval Ls is greater than the locking portion length 212Lx. Therefore, even in a state where the distance in the depth direction X between the first article 91 and the second article 92 is the minimum article distance Ls, there is a locking portion between the first article 91 and the second article 92 in the depth direction X. 212 can be placed appropriately.

Here, when the transfer mechanism 21 arranges the locking portion 212 between the first article 91 and the second article 92 in the depth direction X, the transfer arm 211 provided with the locking portion 212 is It protrudes from the traveling carriage 20 to the back side X2 in the depth direction (see FIGS. 4 to 6). In this case, an error may occur in the amount of protrusion of the transfer arm 211 due to the structure or control of the transfer mechanism 21 .

Therefore, in the present embodiment, the above-described minimum article interval Ls is set to be larger than the sum of the maximum error in the amount of protrusion of the transfer arm 211 (maximum stoppage error of the transfer arm 211) and the locking portion length 212Lx. , a regulating protrusion length 15Lx is set. As a result, even if the transfer arm 211 has an error in the amount of projection, the locking portion 212 can be arranged between the first article 91 and the second article 92 in the depth direction X in that state. can. The "maximum error" is the maximum value of error that can be assumed in terms of the structure or control of the transfer mechanism 21, and is determined by experiments or the like, or is arbitrarily determined in consideration of the reliability of the operation.
