送体Ａに対する係止作用を解除するようにする。This stopper 71 has a proximal end of a lever 74, which is held in contact with the inner part 40a of the receiver 40, integrally fitted to the outer end of a shaft 73 rotatably fitted to the shaft support γ2. With,
The base end of a locking lever 750 in the shape of an angle that locks the right and left front and rear wheels 22 of the conveyed object A on the lifting rail 32 from the outside is integrally fitted to the inner end of the shaft 73, and the lifting frame body 4
When the positioning pin 35 is locked on the upper surface of the receiver 40 and the elevating rail 32 and the loading/unloading rails 14, 15, 16 are aligned, the left and right front and rear conveyed object stops 1 and bumps 7
The tip of the lever 74 of No. 1 abuts and locks on the upper surface of the inner part 40a of the receiver 40 at four locations and rotates upward, and the locking lever 75 integral with this lever 74 also rotates upward. The locking action on the conveyed object A is released.

７４の先端下側に臨ませるようにする。That is, a pair of support frames 81 are fixed to the upper surface of the lower right frame 62 of the main body frame, and the middle part of the air cylinder 82 is rotatably mounted between the pair of support frames 81, and the piston rod 83 of the air cylinder 82 is fixed to the upper surface of the right lower frame 62. Link 8 at the tip of
4 is rotatably connected to a shaft, and the other end of this link 84 is connected to a shaft 86 supported by a bearing 85 on the upper surface of the lower frame 62.
The base of a link 870 is integrally fitted to both ends of this shaft 860, and the upper end of the link 88 is rotatably connected to the tips of the links 87 on both sides. The lower end of the link 88 is rotatably connected to the base end of a lever 90 whose intermediate portion is rotatably supported by U-shaped steels 89 protruding from the lower surfaces of both sides of the lower frame 62. A push-up bar 91 is provided to protrude inward from the tip of the lever 90, and the push-up bar 91 is made to face the bottom of the tip of the lever 74 of the right-side conveyed object stopper 71.

次にこの実施例の作用を説明する。Next, the operation of this embodiment will be explained.

傾斜状の搬入レール１４上を自走してきた被搬送体Ａは
上記レール１４の終端部に設けた図示しないストツパな
どによって係止され待機する。The conveyed object A that has been traveling on the inclined carry-in rail 14 is stopped by a stopper (not shown) provided at the end of the rail 14 and waits.

その間に下降してきた昇降枠体４はその４箇所の位置決

3, the tip of the lever 90 is rotated downward, the push-up bar 91 is lowered, and at the same time, the right-side conveyed object stopper 71 supported by the push-up bar 91 is pushed out by its own weight or the force of a spring (not shown). Then, the locking lever 75 locks the wheels 22 of the conveyed object A.

逆に上記ストツパ７１を開く場合は、上記押上棒９１に
よってこのストツパ７１のレバー７４を押上げる。Conversely, when opening the stopper 71, the lever 74 of the stopper 71 is pushed up by the push-up bar 91.

い。Except for the case where the conveyed object A is transferred to the lower elevating rail 32 in this way, the object A transferred to the lower elevating rail 32 is moved to the stopper 7 at the front and rear of the left and right ends of the elevating frame 4.
1 and will not come off the lifting rail 32.

ついでワイヤロープ３を引上げ昇降枠体４を土段の受具
４０の土方まで上昇させ停止させる。Then, the wire rope 3 is pulled up, and the lifting frame 4 is raised to the earth side of the support 40 of the earth step and stopped.

４４の力で復帰する。During this upward movement, the four positioning pins 35 of the elevating frame 4 lift the inner parts 40a of the four upper holders 40 and pass through them, and after the pins 350 have passed a predetermined distance, the holder 40 It comes off from this pin 35 and returns to its original horizontal state by the force of its spring 44.

ついで上記昇降枠体４をやや下降させ、その４箇所の位
置決めピン３５を上段４箇所の受具４０で係止する。Next, the elevating frame 4 is lowered slightly, and the four positioning pins 35 are locked with the four upper holders 40.

し、その昇降レール３２の芯出しを行なうようにする。When lowering the elevating frame 4 from the -H stage to the lower stage, the elevating frame 4 is slightly raised so that the inner part 40a of the upper stage receiver 40 interferes with the positioning pin 35 of the elevating frame 4. Then, the piston rod 54 of the air cylinder 53 of the holder release device 50 is pushed out, and the upper holder push-down lever 58 is used to push the outer end of the upper holder 40 downward. The bent end 40b is pushed down, and as a result, the inner part 40 of the upper holder 40
Rotate a toward Hijikata and attach it to the positioning pin 3 of the lifting frame 4.
5, and lowers the lifting frame 4 from the upper stage to the lower stage 3o. Then, before the lifting frame 4 descends to the position of the carry-in rail 14 and the lower stage carry-out rail 15, the holder release device 50
The piston rod 54 is retracted, and the lower bracket pressing lever 65 is rotated toward Hijikata via the interlocking rod 60 to release the pressing force, and the lower bracket 40 is returned to the horizontal state by the force of the spring 44. Then, attach the four receivers 40 at the bottom.
The positioning pins 35 at four positions of the elevating frame body 404 are locked, and the elevating rails 32 are centered.

に困難を伴うこともない。Note that since the four positioning pins 35 of the lifting frame 4 are supported by the receivers 40 at the four corners, the transported object A
When the object is transferred from the carrying-in rail 14 to the lifting rail 32, the rails 35, 15 are not misaligned due to the unbalanced load of the conveyed object A, and therefore there is no difficulty when transferring to the carrying-out rail 15.

次に昇降枠体の他の実施例を第９図ないし第１２図に基
づいて説明する。Next, another example of the elevating frame will be described based on FIGS. 9 to 12.

第９図に図示するように搬入レール１４と搬出レール１
６ａとが同−側にある場合はその傾斜が逆になるので、
それに応じて昇降レール３２ａの傾斜も変えてやる必要
がある。As shown in FIG. 9, the carry-in rail 14 and the carry-out rail 1
If 6a and 6a are on the same side, the slope will be opposite, so
It is also necessary to change the inclination of the lifting rail 32a accordingly.

より上方に設ければ左下り傾斜状態になる。Therefore, the lifting frame 4a has one end of the lifting rail 32a rotatably connected to one end of the base frame 95 to which the wire rope 3 is connected by a pin hinge 96, and the locking frame 9 at the other end of the base frame 95.
7, the upper plate portion 3 of the T-shaped steel 30 of the lifting rail 32a is
0a is mounted so as to be movable up and down, and for example, if the mounting position of the right side bracket 40 is provided below the left side bracket 40 as shown by 40e, the lifting rail 32a will be in a state of inclination downward to the right, Also, as shown at 40f, the left receiver 40
If it is placed higher, it will be tilted downward to the left.

なお先の実施例は上下２段のものであるが、さらに多段

て誤まりなくスムーズに行なわせることができる。According to the present invention, the receiver can be rotated only when the elevating frame locking side portion of the receiver is above the elevating frame locking level at the height position where the main body frame is connected to the loading or unloading rails of multiple stages. The lifting rail of the lifting frame supported by the upper surface of the receiver of each stage is positioned concentrically with the loading or unloading rail of each stage, so that It is possible to smoothly transfer objects to be transported in a plurality of stages from the lifting rail to the lifting rail and from the lifting rail to the carry-out rail without any errors.

も容易である。In addition, a holder release device is provided for the above-mentioned tiers of holders to forcibly rotate the holders of each tier upward at the same time, and when the holder of each tier is lowered, the lifting frame support function of each tier is controlled. Because it can be released, the holder can be freely rotated only above the lifting frame locking level, and the lifting frame can be raised freely. The suspension position of the lifting frame can be determined using a receiver at any height, and by making the receivers on each stage release simultaneously, the structure of the receiver release device is simplified and the operation is easier. is also easy.

る。In addition, a fitting groove is formed on the -L side of each stage's receiver to fit the positioning member protruding from the lifting frame, so that the alignment between the lifting rail and the loading or unloading rail of each stage is accurate. In particular, the fitted V-groove can strictly prevent lateral displacement.

The conveyed object on the lifting rail can be carried out by itself to the carrying-out rail on the same side of the carrying-in rail or to the carrying-out rail on the opposite side.
