A horizontal holding transfer gear 12, which meshes with the horizontal holding gear 7 and forcibly transfers between the horizontal transfer rail 1 and the vertical transfer rail 2 while maintaining the horizontal posture of the stocker 6, is pivotally supported. By Stocker 6
The horizontal continuous holding mechanism is configured to continuously transfer the horizontal position. On the other hand, on the other end of the drive shaft 11, a drive gear 15 having a large diameter and a drive gear 16 having a small diameter are integrally supported on a flange 14 which is axially supported by the bearing 9 via a frame 13, and the flange 14 is further supported.

The stocker 6 is transported and continuously transferred by these. A transmission mechanism is configured.

FIGS. 4 to 6 show an embodiment of the second aspect of the invention, in which 21 is a horizontal conveying rail formed in a U-shaped cross section, and the horizontal conveying rail 21 has a conveying start end side and a conveying side. A sprocket (not shown) is arranged on the terminal end side, and an endless chain 22 is positioned and suspended on the horizontal transport rail 21 on the sprocket, and thereby the transport path of the stocker 6 is formed. The stocker control pulley 2 is provided at the center of the left and right side plates 6a and 6b of the stocker 6 that is transported along the horizontal transport rail 21.
3, the base portion 24a of the pin 24, which is fixed to the control pulley 23 and is connected to the endless chain 22 by projecting from the center portion of the side surface of the control pulley 23, is projected in a rectangular shape and fitted into the transport path of the horizontal transport rail 21. And the stocker 6
The horizontal transport holding mechanism is configured to transport the endless chain 22 in the transport path while keeping the horizontal posture.

A pair of left and right cutouts 25 is formed in a required position of the horizontal transfer rail 21 in parallel with the transfer direction, and a servomotor 27 is disposed below the cutouts 25 via a mounting boss 26. A control timing pulley 28, 28 pivotally supported on the mounting boss 26 at a position equidistant from the shaft center of the output pulley 27a of the servo motor 27 in the front-rear direction is interlocked with the output pulley 27a of the servo motor 27 by an endless belt 29. Along with the above-mentioned control timing pulley 2
Control belt pulleys 30, 30 slidably contacting the lower sides of the control pulleys 23, 23 on the stocker 6 side are pivotally supported on the support shafts 28a, 28a of the gears 8, 28, and interlocked by an endless control belt 31. A control mechanism is configured in which the stay 32 is inserted inside the endless control belt 31, the stocker 6 horizontally conveyed to the notch 25 is tilted by the forward and reverse rotations of the servo motor 27, and then returned to the horizontal posture. There is.

In the above embodiment, the stocker control pulley 23 is a toothed pulley, and the endless control belt 3
If 1 is a toothed belt, high-speed control can be performed even when a heavy object is conveyed. Also, if a clutch is mounted on the output pulley 27a instead of the servomotor 27 and is interlocked and connected, the clutch can intermittently operate the power. This allows the stocker 6 to tilt and return horizontally.

Next, the operation of the first and second inventions constructed as above will be described. First, in the first invention, in the stocker 6, the base 8a of the pin 8 connected to the endless chain 5 has the horizontal transport rail 1 and the vertical transport rail 2
Since the stocker 6 is conveyed in a state of being inserted into the stocker 6, the stocker 6 is conveyed while maintaining a horizontal posture, and when the horizontal transfer rail 1 and the vertical transfer rail 2 are continuously transferred, the stocker 6 is transferred to the horizontal holding gear 7 on the stocker 6 side. Since the horizontal holding relay gear 12 on the sprocket 4 side is meshed, the stocker 6 is forcibly fed while maintaining the horizontal posture. Therefore, it is not possible to safely and reliably transport materials such as liquids,
It can be used to convey parts to production lines in factories where space on the site is restricted, and can be effectively used in multilevel parking lots by increasing the size.

Next, in the second aspect of the invention, the stocker 6 is horizontally transported with the base 24a of the pin 24 connected to the endless chain 22 being fitted in the horizontal transport rail 21.
Is transported to the cutout portion 25 of the horizontal transport rail 21,
Since the base portion 24a of the pin 24 is disengaged from the horizontal transport rail 21, the horizontal holding of the stocker 6 is released, and at the same time, the servo motor 27 rotates forward to make a sliding contact with the lower side of the stocker control pulley 23. 30 is rotated to tilt the stocker 6 forward in the transport direction,
After returning to the horizontal posture by the reverse rotation of the servomotor 27, the base portion 24a of the pin 24 is fitted to the horizontal transport rail 21. Therefore, the stocker 6 is transported in the horizontal posture. In this case, since the stay 32 is inserted inside the endless control belt 31, slipping with the control pulley 23 is prevented and tilting is reliably performed. Therefore, according to the work place on the production line, necessary parts used at each work place can be transported in a journal, contributing to the improvement of productivity in combination with the rationalization of parts transportation. You can
