The lateral feed device 8 is supported by a support column 15 and is arranged in pairs on both sides in the longitudinal direction of the tray 7, an engagement mechanism rotated by the drive machine 51, and an engagement mechanism. It is equipped with an engaging mechanism that can be fitted.

The engaging mechanism includes, for example, a housing 52 arranged along the moving direction of the tray 7, a drive sprocket 53 rotatably supported by one end of the housing 52 and driven by a driving machine 51, and a housing. A driven sprocket 54 that is rotatably supported at the other end of the 52 and is paired with the drive sprocket 53, a cord 55 that is endlessly wound around the drive sprocket 53 and the driven sprocket 54, and the drive sprocket 53 and the driven sprocket. It is located between 54 and is arranged so that its horizontal bottom surface is below the lower ends of the sprockets 53 and 54, and the horizontal bottom surface is in sliding contact with the cord-shaped body 55 to apply tension, and the trajectory of the cord-shaped body 55 is substantially ladder-shaped. It includes a guide body 56 and a meshing portion 57 attached to the cord 55 as a pair.

The engaged mechanism is, for example, arranged in pairs at both end portions in the longitudinal direction of the tray 7, and includes an engaged portion 58 that meshes with the meshing portion 57.

The drive machine 51 is arranged in parallel above the drive sprocket 53 so as to be adjacent to each other. Further, the drive cord 61 is wound around the drive sprocket 51A of the drive 51 and the drive sprocket 53A of the drive sprocket 53 in an endless manner, and when the drive 51 is driven, the drive sprocket 51A is driven. The drive sprocket 53 is driven via the cord 61 and the drive sprocket 53A.

The guide body 56 is fixed to the housing 52, is located between the drive sprocket 53 and the driven sprocket 54, and is located below the guide body 56 by being arranged so that the horizontal bottom surface thereof is below the lower ends of the sprocket 53 and 54. The cord 55 is pushed down toward the tray 7, the trajectory of the cord 55 is substantially trapezoidal, and a device is devised so that the meshing portion 57 attached to the cord 55 can be smoothly meshed with the meshed portion 58. Has been done. Further, in the guide body 56, the spacing dimension between both end portions 56A and 56B in the longitudinal direction of the horizontal bottom surface is the spacing dimension between the paired meshing portions 57 and the spacing dimension between the paired meshed portions 58. It is set to be substantially the same. As a result, when the horizontal bottom surface of the guide body 56 is in sliding contact with the cord-like body 55 to apply tension between the drive sprocket 53 and the driven sprocket 54, and the paired meshing portion 57 is located in the lower row of the cord-like body 55. The spacing dimension is set to a predetermined value, and the meshing operation with the meshed portion 58 is smoothly performed. Further, the guide body 56 has curved surfaces at both end portions 56C and 56D in the longitudinal direction, so that the cord-like body 55 is smoothly brought into contact with and separated from each other.

The meshing portion 57 is composed of meshing portions 57A, 57B, 57C, 57D attached to the cord 55, and the meshing portions 57A, 57B are paired and the meshing portions 57C, 57D are paired, and two sets of meshing portions are engaged. The portion 57 is provided on the cord-like body 55. The spacing dimensions of the meshing portions 57A and 57B and the spacing dimensions of the meshing portions 57C and 57D are set to be substantially the same as the spacing dimensions of the meshed portions 58A and 58B described later, respectively. When the two meshing portions 57A and 57B in the body 55 mesh with the meshed portions 58A and 58B, the two meshing portions 57C and 57D in the upper row cord-like body 55 are in the lower row cord-like body 55. It is located substantially directly above the two meshing portions 57A and 57B. Further, the distance between the meshing portions 57A, 57D or the meshing portions 57B, 57C is set to be substantially the same as the distance between the meshed portions 58A, 58C provided on the adjacent trays 7, for example, the trays 7A, 7B. Further, each meshing portion 57 has a connecting portion 57E fixed to the cord-shaped body 55, and a spherical convex portion 57F attached to the tip of the connecting portion 57E and capable of being fitted into the spherical concave portion 58C of the meshed portion 58 to be described later. It is equipped with.

The meshed portion 58 includes meshed portions 58A and 58B arranged in pairs at one of the longitudinal side ends of the tray 7, and the distance between the meshed portions 58A and 58B is the meshing portion 57A. , 57B and the spacing between the meshing portions 57C and 57D are substantially the same. Further, the meshed portion 58 includes a spherical recess 58D into which the spherical convex portion 57F of the meshing portion 57 can be fitted, and a wide portion 59E extending upward from the spherical recess 58D.

In this way, the spacing dimension between both ends 56A and 56B in the longitudinal direction of the horizontal bottom surface of the guide body 56, the spacing dimension between the paired meshing portions 57, and the spacing dimension between the paired meshed portions 58 are substantially the same. When both end portions 56A and 56B of the meshing portion 57 and the guide body 56 are in substantially opposite positions, the meshing portion 57 is arranged to mesh with the meshed portion 58. The drive machine 51, the housing 52, the drive sprocket 53, the driven sprocket 54, the cord-like body 55, the guide body 56, the meshing portion 57, and the meshed portion 58 are arranged as a set in each of the lateral transfer paths 11 and 12. Has been done.

With the above configuration, the tray 7 is laterally fed in the lateral transfer paths 11 and 12 as follows. When in the initial state as shown in FIGS. 3 and 4, a lateral feed command is output from a control device (not shown). 7 When moving one unit, the drive sprocket 51 is driven, and the drive sprocket 53 is rotated via the drive sprocket 51A, the drive cord 61, and the drive sprocket 53A. In this way, when the drive sprockets 53 arranged in pairs on both sides in the longitudinal direction of the tray 7 are rotated in synchronization with each other and the cord 55 is circulated in a counterclockwise direction, the meshing portions 57A and 57B are changed. , The spherical convex portion 57F slides from the spherical concave portion 58D of the meshed portions 58A and 58B to the wide portion 58E, and pushes the tray 7A to the right. At this time, since the tray 7 rows are connected by the couplers 42A and 42B, respectively, as described above, the other trays 7 are also moved to the right in conjunction with the movement of the tray 7A to which the driving force is transmitted by the driving machine 51. Move sideways.

Next, when the drive sprocket 53 is further rotated, the cord 55 is in a state as shown in FIG. 6, the meshing portion 57B is disengaged from the meshed portion 58B, and the meshing portion 57D is provided on the front side in the traveling direction of the tray 7B. It engages with the meshing portion 58C. At this time, in the meshing portion 57B, since the trajectory of the cord-like body 55 is located between the guide body 56 and the drive sprocket 53 and pushed up, the spherical convex portion 57F is inclined, and the meshing portion 57B efficiently uses the meshed portion 58B. While pushing it out, it separates. On the other hand, the spherical convex portion 57F of the meshing portion 57D slides from the wide portion 58E of the meshed portion 58C to the spherical concave portion 58D to pull the tray 7B. Further, since the meshing portion 57A is located between both ends 56A and 56B in the longitudinal direction of the horizontal bottom surface of the guide body 56 and is guided, the meshing portion 57B and the meshed portion 58B are slightly disengaged. During the above time, the meshed portion 58A is in mesh with the meshed portion 58A, and the meshed portion 58A is pushed out to the right. As a result, the 7 rows of trays continue to move laterally.

Next, when the drive sprocket 53 further rotates and the tray 7 row further moves, the meshing portion 57A is disengaged from the meshed portion 58A, and the meshing portion 57C engages with the meshed portion 58F provided on the rear side in the traveling direction of the tray 7B. I will meet. Here, the operation in which the meshing portion 57C engages with the meshed portion 58F will be described. FIG. 7 is an explanatory diagram illustrating the meshing operation between the meshed portion and the meshed portion.

As shown in FIG. 7A, when the meshing portion 57C is in a position facing the meshed portion 58F, the spherical convex portion 57F first becomes the wide portion 58E of the meshed portion 58C as shown in (b). It abuts and then slides from the wide portion 58E to the spherical recess 58D, as shown in (c). At this time, since the trajectory of the cord-shaped body 55 is pushed down by the guide body 56, the meshing portion 57C is inclined, and the contact with the wide portion 58E and the sliding from the wide portion 58E to the spherical recess 58D are smooth. It will be done. After that, as shown in (d), the spherical convex portion 57F fits into the spherical concave portion 58D. As a result, the meshing portion 57D engages with the meshed portion 58C of the tray 7B, and the meshing portion 57C engages with the meshed portion 58F, respectively, in an initial state. At this time, tension is applied to the cord-like body 55 between the drive sprocket 53 and the driven sprocket 54 by sliding the horizontal bottom surface of the guide body 56, and the spacing dimension of the paired meshing portions 57C and 57D is surely determined. Therefore, the meshing with the meshed portions 58C and 58F is smoothly performed. Further, in the initial state, the paired meshing portions 57C and 57D are located on the horizontal bottom surface of the guide body 56, respectively, so that a stable stopped state can be maintained. In this way, the process of moving the 7 rows of trays of the horizontal transfer path 11 toward the empty space 13 to the right in the drawing by one tray 7 is completed.

According to the present embodiment, by arranging the drive machine 51 independently on both sides of the tray 7, it is not necessary to arrange the drive machine 51 below the tray 7, and the drive machine 51 is driven as in the conventional case. The shaft can be omitted, whereby the dimension between the floor and the tray 7 can be suppressed, and thus the space of the parking device and the building can be saved.

Further, the engaging mechanism is arranged along the moving direction of the tray 7, and the driven sprocket 53 rotated by the driving machine 51 and the driven sprocket 54 paired with the driving sprocket 53 and arranged along the moving direction of the tray 7. The tray 7 is composed of a cord-like body 55 that is endlessly wound around the drive sprocket 53 and the driven sprocket 54, and a meshing portion 57 that is attached as a pair to the cord-like body 55. By forming a pair of the meshed portions 58 which are arranged in pairs at both end portions in the longitudinal direction and mesh with the meshing portion 57, the lateral feed speed can be improved. That is, the tray 7 can be moved laterally for a relatively long distance with one action, and the tray 7 can be moved laterally at high speed.

Further, it is located between the drive sprocket 53 and the driven sprocket 54, and its horizontal bottom surface is arranged so as to be below the lower ends of the sprocket 53 and 54. A guide body 56 having a substantially trapezoidal trajectory of 55 is provided, and the distance between both ends 56A and 56B in the longitudinal direction of the horizontal bottom surface of the guide body 56, the distance between the paired meshing portions 57, and the paired meshing. Arrangement in which the meshing portion 57 meshes with the meshed portion 58 when the spacing dimensions between the portions 58 are substantially the same and the mating portions 57 paired with both end portions 56A and 56B in the longitudinal direction of the horizontal bottom surface are in substantially opposite positions. Therefore, the meshing portion 57 can be smoothly meshed with the meshed portion 58, and the tray 7 can be efficiently laterally fed. As a result, the vibration damping property and the quietness are excellent, and the operation efficiency is excellent. It is possible to realize a good horizontal feed device 8.

Furthermore, with a simple structure in which the boat-shaped guide body 56 is attached to the lower part of the housing 52, the main part trajectory of the cord-shaped body 55 is formed, and the meshing portion 57 is positioned to reduce the number of parts. The device can be further simplified.

Further, in the guide body 56, since both end portions 56C and 56D in the longitudinal direction are curved surfaces, the cord-like body 55 can be smoothly brought into contact with and separated from each other, and the generation of sound vibration can be suppressed. Can be done.

Further, the drive machine 51 is arranged in parallel adjacent to the drive sprocket 53 above the drive sprocket 53, and the drive cord 61 is wound around the drive sprocket 51A of the drive machine 51 and the drive sprocket 53A of the drive sprocket 53 in an endless manner. By adopting a hangable structure, it is possible to prevent the drive machine 51 from traveling to the outside of the support column 15 and to reduce the width dimension of the device.

Here, the lateral feed device 8A according to another embodiment of the present invention will be described. FIG. 8 is a side view showing a configuration of a drive device for a lateral feed device according to another embodiment of the present invention.

The main difference between the lateral feed device 8A according to the other embodiment and the lateral feed device 8 according to the above-described embodiment is the arrangement of the drive machine 71. As shown in FIG. 8, the drive machine 71 of the lateral feed device 8A according to another embodiment of the present invention is arranged adjacent to the drive sprocket 53 in the lateral direction, and the drive shaft 71A thereof is arranged adjacent to the shaft 53B of the drive sprocket 53. It is directly connected to.

In another embodiment, when a lateral feed command is output from a control device (not shown) and the drive machine 71 is driven, the drive shaft 71A rotates the shaft 53B of the drive sprocket 53 and circulates the cord 55. ..

According to another embodiment, the drive machine 71 of the lateral feed device 8A is driven like the lateral feed device 8 of the above-described embodiment because the drive shaft 71A is directly connected to the shaft 53B of the drive sprocket 53. The machine sprocket 51A, the drive sprocket 53A, and the drive cord 61 are not required, and the number of parts of the device can be reduced, whereby the cost can be reduced.

The embodiment of the parking device of the present invention has been described above, including its action and effect. However, the parking device of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the invention described in the claims.
