CONSTITUTION:A moving member 14 is located at the left end of its path and a support member 7 is at the lowermost position L, with a hook 22 directed to the leftside position A. Thus, an engaging portion 22a is positioned directly under a grip 27a of a container 27 on a shelf. Then, the support member 7 is moved upward to an intermediate position M, where the engaging member 22a is brought in engagement with the grip 27a of the container 27. Then, the moving member 14 is moved to the right end of the path. As the result, the container is drawn to be moved in a container pulling in/pushing out path 4, and the container 27 is pulled in the central portion of the path and slides on a support guide bar 5 between positioning guide bars 6 to an unloading position. This construction allows transfer of a high container.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention provides an automated warehouse system equipped with shelves for storing containers with handles and running lanes for loading and unloading the containers to and from the shelves. The present invention relates to a hook-type transfer device installed on the lifting carriage of the traveling lane, which uses a container pull-in/push hook that engages with the handle of the container.

(Prior Art and its Problems) The hook in a conventional hook-type transfer device of this type has a muscle level that can engage with the handle of the container located on the container pull-in and push-out route, and a bar located on the route. The container was constructed so that it could be moved back and forth along the length of the path at a low level that could pass under the container. In such a conventional bag Tl, it is necessary to secure a space below the container pull-in and push-out path to form a reciprocating path for the hook and its lifting/lowering drive means, so it is necessary to secure a space on the crane side where this transfer device is installed. The vertical height and thickness of the lifting carriage become thicker, and the height above the floor surface of the container retraction and extrusion path when the lifting carriage is at the lowering limit position becomes higher. This has the disadvantage that the storage efficiency of the shelves is reduced.

In addition, for the reasons mentioned above, it is not possible to make the lifting stroke of the hook large, so it is difficult to use a general plastic container with a handle on the upper edge to engage the hook, especially in height. It was unsuitable as a transfer device for expensive containers.

(Means for Solving the Problems) The present invention proposes a hook-type transfer device that can solve the above-mentioned conventional problems. erect the parts,
The support member supports a movable body so as to be able to reciprocate in the length direction of the path, and a hook for drawing in and pushing out a container is provided on the underside of the movable body, and furthermore, a means for reciprocating the movable body and the hook are moved up and down. A lifting drive means is provided,
The present invention is configured such that the hook can be moved in the length direction of the path above a container located on the path by raising the support member.

(Example) An example of the present invention will be described below based on the attached illustrative drawings.

In FIGS. 1 to 3, reference numeral 1 denotes an elevating carriage that is supported in a vertically movable manner by supports 2 of lanes for entering and exiting the warehouse. is composed of a pair of container supporting guide bars 5 and a pair of container positioning guide bars 6. Reference numeral 7 denotes a support member that can be raised and lowered on the container pull-in and push-out route 4, and is cantilevered so as to be raised and lowered on a pair of lifting guide rails 8 that are erected on the lifting cabin 1 between the route 4 and the support column 2. At the same time, it is provided with a female threaded body 10 which is screwed onto a vertical elevator V4 drive screw shaft 9 supported on the elevator cabin 1 between both the elevator guide rails 8. Reference numeral 11 denotes a motor interlockingly connected to the screw shaft 9 through a chain transmission means 12.

The support member 7 includes a container drawing and pushing path 4.
A pair of lateral movement guide lofts 13 are constructed along the length direction of the path 4 directly above the lateral movement guide rod 1.
3, a movable body 14 is movably supported. Reference numeral 15 denotes a reciprocating means for driving the movable body 14, and a portion of the movable body 1 is
Driving chino 1 stretched along the reciprocating path of 4.
8, and a motor 19 that drives the drive gear wheel 16, and the drive chino 18 and the movable body 14 are connected to a fourth
As shown in the drawings and FIG. 6, they are connected by a connecting fitting 20.

As shown in FIGS. 4 to 6, the movable body 14 is formed in a U-shape, and a vertical rotation support shaft 21 is provided under the bottom of the movable body 14.
The hook 22 is pivotally supported through the movable body 14, and the rotary support shaft 21 is directly connected to the vertical output shaft 23a of the motor 23 installed in the recess of the movable body 14. The hook 22 is formed with a retaining portion 22a that stands vertically only at one end,
As the hook 22 is rotated forward and backward within a range of 180 degrees by the motor 23, the posture (orientation) of the hook 22 is changed so that the retaining portion 22a is in the reciprocating direction of the movable body 14, as shown in FIG. At this point, the movable body 14 is selectively switched to a posture A facing left, a posture B facing right, and a neutral posture C facing right sideways with respect to the reciprocating direction of the movable body 14. Reference numeral 24 denotes a click spring pole attached to the hook 22, which fits into positioning recesses 26a to 26c formed in an arc-shaped member 25 attached concentrically to the rotational support shaft 21 at the bottom of the movable body 14. By aligning the hooks 22, the hooks 22 are positioned in each posture A-C.

According to the hook-type transfer device configured as described above, the support member 7 can be moved upward by rotating the screw shaft 9 in the forward direction by the motor 11, and the support member 7 can be moved upward by rotating the screw shaft 9 in the reverse direction. can be moved downward.

Further, by rotating the driving chino 18 in the normal direction by the motor 19 via the driving gear 16, the movable body 14 can be moved back and forth from one end of the reciprocating path to the other end, and by rotating the driving chino 18 in the reverse direction. The movable body 14 can be moved backward from the other end to one end of the reciprocating path. By rotating the hook 22 in forward and reverse directions within a range of 180 degrees using the motor 23, it is possible to switch to any posture among leftward posture A, rightward posture B, and neutral posture C.

The method for using such a hook-type transfer device is described below when a container 27 supported in a shelf or on a handling platform on the left side of the elevating gear ledge 1 is transferred onto the elevating gear 1 and transported by a crane. For example, as shown by the solid line in FIG. 7, the movable body 14 is located at the left end of the reciprocating path, the support member 7 is located at the lower limit position shown by the solid line in FIG. Switch to posture A. As a result, the engaging portion 22a of the hook 22 is located directly below the handle 27a of the container 27 within the shelf or on the handling platform. In other words, the elevator elevator 1 is stopped at a height at which such a state occurs. Note that the downward movement of the support member 7, the leftward movement of the movable body 14, and the rotation of the hook 22 in order to achieve the above-mentioned state are performed in an appropriate manner to prevent the hook 22 from colliding with the handle 27a of the container 27. It is best to do it in that order.

Next, the support member 7 is raised to an intermediate position M shown by the imaginary line in FIG.
7 and then move the movable body 14 from the left end to the right end, the container 27 in the shelf or on the handling platform is pulled by the hook 22 and the elevator lift 1 is pulled by the hook 22 as shown in FIG. The container moves onto the upper container pull-in and push-out route 4 and is drawn to the center position of the route 4.

At this time, the container 27 slides on the support guide bar 5 between the positioning guide bars 6.

Once the container 27 is pulled onto the elevating carriage 1 as described above, the container 27 is transported to the container unloading position by the movement of the crane and the elevating and lowering of the elevating carriage 1. Next, the container 27 on the elevating carriage 1 is transferred to a double-opening platform or shelf adjacent to the elevating carriage 1, but when the direction in which the container is lowered is to the left of the elevating carriage 1, as shown in FIG. By leaving the hook 22 engaged with the handle 27a of the container 27 as it is and moving the movable body 14 to the left end after the lifting carriage 1 has stopped adjacent to the predetermined container unloading position, the container can be pulled in. Container 2 on extrusion path 4
7 to the left by the hook 22, and then, by lowering the supporting member 7 to the lowering limit position and rotating the hook 22 to the neutral position C, the hook 2
2 can be removed from the handle 27a of the container 27.

When the container unloading direction is to the right, the support member 7 is lowered to the lowering limit position as shown by the imaginary line in FIG. After removing it from the handle 27a, the support member 7 is raised to the upper limit position H as shown by the solid line in FIG. 9, and the hook 22 is displaced to a position above the container 27. Up to iI above container 27! Make it l1yi and move it. Thereafter, as shown in FIG. 10, the support member 7 is lowered to the lowering limit position, and the hook 22 is rotated to switch to the right-facing position C, and the lifting carrier 1 stops at a predetermined position adjacent to the container unloading position. 1st O after
By moving the movable body 14 from the left end to the right end as shown by the imaginary line in the figure, the container 27 can be pushed out to the right by the hook 22 in the rightward orientation C. After this extrusion is completed, the hook 22 is switched to the neutral position C.

When the container 27 supported in the shelf or on the loading platform on the right side of the lifting carriage 1 is transferred onto the lifting carriage 1 and transported by crane, the hook 22 is attached to the handle 27b on the left side of the container 27. The container 27 may be pulled onto the path 4 by engaging the joint portion 22a.

In addition, if the movable body 14 is configured to be at a position slightly before the end of the stroke when the container 27 is pulled in to the center position of the container pull-out and push-out path 4, the support member 7 can be moved to the lowering limit position after the container pull-in is completed. After lowering, the movable body 1 is moved without switching the hook 22 to the neutral position C.
It is also possible to move the hook 22 to the end of the stroke, remove the hook 22 from the handle 27a or 27b, and then raise the support member 7.

In addition, a container transport conveyor is installed in the container pull-out and push-out route 4, the container 27 pulled in by the hook 22 is conveyed to the center position of the route 4 by the conveyor, and the container 27 sent out to the limit position by the conveyor is transferred to the It can also be configured to be pushed out to a predetermined position by the flap 22.

In the embodiment described above, the lifting/lowering driving means for the hook 22 includes the lifting/lowering support member 7, the lifting/lowering drive screw shaft 9, the female screw body 10,
The hook 22 is configured to be raised and lowered together with the movable body 14 and the support member 7, and the lateral movement guide rod 13 that supports the movable body 14 is raised and lowered with respect to the support member 7. By doing so, the hook 22 can be raised and lowered together with the movable body 14, or only the hook 22 can be raised and lowered relative to the movable body 14.

In addition, in the embodiment, the hook 2 for drawing in and pushing out the container
By rotating 2, one engaging part 22a provided at one end of the hook 22 can be used as a retaining part for pulling in from the left side and pushing out to the right, and a holding part for pulling in from the right side and pushing out to the left. Although the hook is configured so that it can also be used as a retaining part, when using a hook having the two engaging parts at both left and right ends, the hook can also be fixedly installed on the lower side of the movable body 14. In this case, as explained earlier, when the container 27 is pulled in to the median value 1 of the container pull-out path 4, the movable body 14 is configured to be at a position slightly before the end of the stroke, and after the container pull-out path 4 is completed, After lowering the hook, the movable body 14 must be moved to the end of its stroke to remove the retaining portion of the hook from the handle 27a or 27b.

(Operations and Effects of the Invention) According to the hook two transfer device of the present invention that can be implemented as described above, the movable body that supports the hook is supported by a support member that can be raised and lowered and is installed above the container pull-in and push-out path. When the hook is moved to the rear side of the container in order to push out the container pulled into the route by the hook in the same direction as the retracting direction, the hook can be moved above the container. Therefore, there is no need to secure a space below the container pull-in/push-out path to form a reciprocating path for the hook and its lifting/lowering driving means, unlike in the conventional case. Therefore, it is possible to reduce the vertical height and thickness of the elevating carriage on the crane side where this transfer device is installed, and to lower the height above the floor of the container pull-in and push-out route when the elevating carriage is at the lower limit position. I can do it. Therefore, the height of the lowest stage of the container storage section on the shelf side can be lowered, thereby increasing the storage efficiency of the shelf.

In addition, since the hook can have a thick lifting stroke, it can be used to handle containers of various heights, such as general plastic containers that have a handle on the upper edge that engages the hook. It can be effectively used as a loading device.
