  The horizontal circulation parking apparatus has horizontal transfer paths 10 and 10 that are parallel to each other and vertical transfer paths 11 and 11 that are orthogonal to the horizontal transfer paths 10 and 10, and these are alternately connected to form a rectangular pallet circulation. Forming a road. In this pallet circulation path, a plurality of pallets 13, 13,... Are arranged except for the empty spaces 12, 12 provided at a pair of diagonal positions, and the pallets 13 are sequentially directed toward the empty spaces 12, 12. The vehicle is circulated by laterally feeding (arrow X direction) and vertically feeding (arrow Y direction) to accommodate the vehicle.

  FIG. 2 is a front view showing a connecting structure of pallets 13 and 13 adjacent in the horizontal direction (arrow X direction). A roller 15 is pivotally attached to the lower surface of each pallet 13, 13, and each pallet 13 can move laterally on a traveling rail 16 laid on the floor surface by rolling of the roller 15. Yes. On both lateral sides of each pallet 13, an inverted U-shaped connector 14 a and an L-shaped connector 14 b are provided so as to protrude and are adjacent when the pallet 13 is positioned on the horizontal transfer paths 10, 10. When the couplers 14a and 14b of the pallets 13 and 13 are hooked and coupled to each other and are transported through the vertical transport path 11, the couplers 14a and 14b slide with each other at the source to be uncoupled, and the destination Then, the adjacent pallet 13 and the couplers 14a and 14b are engaged and coupled.

  With such a configuration, when any one of the pallets 13 in the lateral transfer paths 10 and 10 is laterally driven, the entire pallets 13 and 13 positioned on the same lateral transfer path 10 are interlocked with each other. To move. Each of the lateral transfer paths 10 and 10 includes lateral feed devices 20 and 20 that laterally move one pallet 13 at an arbitrary position.

  3 and 4 are a side view and a front view showing the transverse feeding device 20, respectively. In the figure, a drive shaft 21 is rotatably provided below the traveling rail 16 with the longitudinal direction of the pallet 13 as an axis. The drive shaft 21 is slightly longer than the length of the pallet 13 in the longitudinal direction. Drive sprockets 22 and 22 are fixed near both ends, and a prime mover 31 such as a geared motor is connected to one end to be driven to rotate. The

  An intermediate sprocket 23 and a pair of transverse feed drive sprockets 25 that are concentrically fixed about a shaft 29 as a rotation shaft are rotatably provided obliquely above the two drive sprockets 22 and 22 when viewed from the front. A drive chain 24 is wound endlessly between the intermediate sprocket 23 and the drive sprocket 22, and the intermediate sprocket 23 or the lateral feed drive sprocket 25 is coaxial with the rotation of the drive shaft 21 or the drive sprocket 22. Driven by rotation. Note that the above-described configuration described in this paragraph and the configuration described below are the same in both the front and rear end portions of the pallet 13, and therefore only one of the configurations will be described.

  A driven sprocket 30 having the same pitch circle as that of the lateral feed drive sprockets 25 and 25 is rotatably provided at a position spaced apart from the lateral feed drive sprocket 25 in the horizontal direction, and the lateral feed drive sprocket 25 and the driven sprocket 30 are separated from each other. A transverse feed chain 26 composed of two rows of chains is wound between them. Between the two rows of the transverse feed chain 26, pin-shaped attachments 27 are installed at four positions. The attachment positional relationship of these attachments 27 is on the vertical center line of the transverse feed drive sprocket 25. When the attachments 27 and 27 are respectively located at two upper and lower positions, the attachments 27 and 27 are located at two upper and lower positions on the vertical center line of the driven sprocket 30. In other words, each attachment 27 has a distance between the center between the lateral feed drive sprocket 25 and the driven sprocket 30 and the length of the half circumference of the pitch circle of the lateral feed drive sprocket 25 and the driven sprocket 30 alternately. The cross feed chain 26 is provided.

At this position, the attachment 27 moves forward in the traveling direction of the pallet 13c. It engages with the engagement plate 28 provided in the above. After that, the pallets 13b and 13c are pulled by the lateral feed chain 26 or the attachment 27 and moved laterally.

  Next, as shown in FIG. 7, when the pallet 13b moves and the engaging plate 28 behind the pallet 13b in the moving direction passes immediately above the axis of the driven sprocket 30, the attachment 27 is detached from the engaging plate 28, and then the pallet 13b. Is moved by being pushed by the subsequent pallet 13c. When the pallets 13a, 13b, and 13c are further moved, both the engaging plates 28 of the pallet 13c are positioned immediately above the axis of the laterally driven drive sprocket 25 and the driven sprocket 30 to be in the initial state shown in FIG. .

  In this way, in the series of operations, the attachment 27 is engaged with any of the engagement plates 28, whereby the pallet 13 can be continuously laterally fed. If the prime mover 31 is started and stopped as necessary, the pallet 13 can be moved and stopped at an arbitrary position. Further, when the pallet 13 is moved in the direction opposite to the arrow X1 direction, the pallet 13 can be moved in the reverse order as described above by driving the motor 31 in the clockwise direction on the drawing. .
