The insertion piece 54 is fitted into the depression 68 in contact with the entire depression 68, and the insertion piece 54 is locked (latched) to the receiving member 64. That the insertion piece 54 is locked to the receiving member 64 means that the slide member 55 is locked to the receiving member 64.
5A and 5B, the holder 53 is shown with a part omitted.

The insertion piece 58 and the receiving member 64a have the same shape as the insertion piece 54 and the receiving member 64, respectively (that is, the insertion piece 58 is formed in a conical shape with a diameter reduced toward the front side, An upwardly inclined portion that rises upward is provided on the lower side, and a downwardly inclined portion that is lowered toward the forward side is provided on the upper side. The receiving member 64a has substantially the same angle as the upwardly inclined portion of the insertion piece 58. And a dent having an inclined lower side inclined part and an upper inclined part inclined at substantially the same angle as the first downward inclined part of the insertion piece 58).
Further, the relationship between the slide member 59 and the receiving member 64a is the same as the relationship between the slide member 55 and the receiving member 64, and the slide member 59 receives the upwardly inclined portion of the insertion piece 58 by moving forward to the advanced position. The insertion piece 58 is engaged (latched) with the receiving member 64a in a state of contacting the lower inclined portion of the member 64a and receiving the forwardly inclined portion of the insertion piece 58 with the upper inclined portion of the member 64a. That the insertion piece 58 is locked to the receiving member 64a means that the slide member 59 is locked to the receiving member 64a.

The carriage 12 is kept at the article loading / unloading position when the insertion piece 54 is locked to the receiving member 64 and the insertion piece 58 is locked to the receiving member 64a at one article loading / unloading position.
Here, when the insertion pieces 54 and 58 are not locked to the receiving members 64 and 64a, respectively, when the article 11 is newly loaded on the carriage 12 at the article loading / unloading position, an increase in the load applied to the carriage 12 is caused. The carriage 12 is lowered in accordance with the elongation of the wire ropes 19 and 22 generated. Depending on the degree of lowering of the carriage 12, the loading of the carriage 12 onto the article 11 cannot be stably completed.

Further, when the article 11 is unloaded from the carriage 12 in the article unloading position in a state where the insertion pieces 54 and 58 are not locked to the receiving members 64 and 64a, the load applied to the carriage 12 is reduced. 12 rises due to the shortening of the wire ropes 19, 22, and depending on the degree of the rise, the operation of lowering the article 11 from the carriage 12 cannot be performed stably.

Therefore, in the present embodiment, after the carriage 12 is raised or lowered and moved to one article loading / unloading position, the loading / unloading of the article 11 with respect to the carriage 12 is completed at the article loading / unloading position. In the meantime, the inserted pieces 54 and 58 are held in the receiving members 64 and 64a respectively. Therefore, the raising / lowering of the carriage 12 due to the increase / decrease of the load applied to the carriage 12 is suppressed, and the loading / unloading of the articles 11 with respect to the carriage 12 can be stably performed.
Then, after the loading and unloading of the article 11 with respect to the carriage 12 is completed, the insertion pieces 54 and 58 are removed from the receiving members 64 and 64a, respectively, and the insertion pieces 54 and 58 are locked to the receiving members 64 and 64a, respectively. Canceled.

Further, after the article 11 is loaded on the carriage 12 at the article loading / unloading position and the load applied to the carriage 12 is increased, the state where the insertion pieces 54 and 58 are respectively locked to the receiving members 64 and 64a is released, the carriage 12 Descends. On the contrary, after the article 11 is unloaded from the carriage 12 at the article unloading position and the load applied to the carriage 12 is reduced, when the state where the insertion pieces 54 and 58 are locked to the receiving members 64 and 64a is released, the carriage 12 rises.

Here, after the article 11 is loaded on the carriage 12 at the article loading / unloading position, when the insertion pieces 54 and 58 are respectively removed from the receiving members 64 and 64a, the insertion piece 54 is, as shown in FIG. Until it moves away from the dent 68, it moves backward while maintaining the state in which the upward inclined portion 65 is in contact with the lower inclined portion 69, and this is the same between the insertion piece 58 and the receiving member 64a. Therefore, until the insertion pieces 54 and 58 are completely removed from the receiving members 64 and 64a, the carriage 12 is gradually lowered in accordance with the retreat of the slide members 55 and 59, and a sudden drop is prevented. .

On the other hand, when the articles 11 are unloaded from the carriage 12 at the article loading / unloading position, when the insertion pieces 54 and 58 are removed from the receiving members 64 and 64a, the insertion pieces 54 are recessed as shown in FIG. Until it moves away from 68, it moves backward while maintaining the state in which the downwardly inclined portion 66 is in contact with the upper inclined portion 70, and this is the same between the insertion piece 58 and the receiving member 64 a. As a result, the carriage 12 gradually rises as the slide members 55 and 59 are retracted until the insertion pieces 54 and 58 are completely removed from the receiving members 64 and 64a, respectively, and a sudden rise is prevented. The
6A and 6B, a part of the holder 53 is omitted.

Further, since the insertion piece 54 is connected to the bar 52 so as to be tiltable at a predetermined angle and to be movable in a predetermined range, the shaft center of the insertion piece 54 is a recess 68 of the receiving member 64. Even if the insertion piece 54 is inserted into the depression 68 in a state that does not coincide with the center of the insertion piece 54, the insertion piece 54 can be smoothly fitted into the depression 68. Note that the maximum tilt angle of the insertion piece 54 with respect to the bar 52 and the maximum parallel movement width of the insertion piece 54 with respect to the bar 52 are adjusted within a range that maintains the state where the carriage 12 is placed at the article unloading position. . The same applies to the relationship between the insertion piece 58, the bar 56, and the receiving member 64a.

The slide members 55 and 59 and the receiving members 64 and 64a include two sets, that is, a set of the slide member 55 and the receiving member 64 and a set of the slide member 59 and the receiving member 64a. Are arranged at a distance from the center of the carriage 12 to the left side (one side) in plan view, and the other set of receiving members 64a is located on the right side (the other side) from the center of the carriage 12 in plan view. The one set of slide members 55 is advanced toward one side and locked to one set of receiving members 64, and the other set of slide members 59 is moved to the other side. It moves forward and is locked to the other set of receiving members 64a. Therefore, compared to the case where one set of receiving members and the other set of receiving members are both disposed at the same distance from the center of the carriage 12, the carriage 12 is stably placed at the article unloading position. It is possible to fix.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and all changes in conditions and the like that do not depart from the gist are within the scope of the present invention.
For example, the conveying device may be a stacker crane or may be a type in which an article is directly placed on a carriage without being placed on a pallet.
Further, the carriage does not move up and down, and may move laterally to convey the article, and does not need to be suspended by a wire rope.
The slide member does not have to advance or retract horizontally, and may advance or retract in an oblique direction, for example.

Furthermore, the set of the slide member and the receiving member may be one set or three or more sets, and the receiving member does not need to be fixed to the support column.
Further, the insertion piece does not need to be conical, for example, a plate material is bent into a V shape, and includes an upwardly inclined portion on one side and a downwardly inclined portion on the other side based on the bending position. It may be a shape. The insertion piece does not need to be tiltable with respect to the support, and need not be able to move in parallel.

Further, when only the carriage lowering due to the loading of the article is suppressed by locking the insertion piece to the receiving member (that is, when the carriage is not lifted by lowering the article), the insertion piece has the first downward inclined portion. The receiving member does not need to have an upper inclined portion. In that case, it is sufficient to suppress the carriage from being lifted by lowering the article by a mechanism other than the mechanism for locking the slide member to the receiving member.
