Abstract

PROBLEM TO BE SOLVED: To provide a device to stop a traverser at a stacker crain transferring position easily. SOLUTION: In an automatic storehouse system composed of a stacker crain to output and input a loaded long size baggage from a storaging shelf; a traverser to move the stacker crain to a neighboring device; and an apparatus to receive and deliver the baggage in order to store the baggage; a pin having a sliding function is provided at the traverser 3 side, while a cam follower to guide the pin at a rack 2 side, in order to transfer the stacker crain from the upper and the lower running rails 4 and 5 in the rack 2, to the upper and the lower running rails 6 and 7 on the traverser 3, and the centerings of the upper and the lower running rails 6 and 7 on the traverser 3, and the upper and the lower running rails 4 and 5 in the rack 2, are carried out by sliding the pin, and being guided according to the cam follower.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a traverser stop positioning device.

[0002]

2. Description of the Related Art When transferring a stacker crane body for handling long loads to a traverser, it is necessary that the vertical traveling rails be centered. It becomes more difficult to put out the lower the level difference between the upper and lower running rails.

SUMMARY OF THE INVENTION The present invention provides an apparatus for easily stopping a traverser at a stacker crane transfer position with respect to a conventional automatic warehouse system.

Further, the present invention provides a traverser stop positioning device having a function of releasing a stacker crane forcible stop device at an end of a vertical rail in a rack by sliding a pin on a traverser side.

[0005]

SUMMARY OF THE INVENTION A traverser stop positioning device according to the present invention comprises a power cylinder disposed near an upper traveling rail and a lower traveling rail of a traverser body, a pin connected to the power cylinder, and a guide for guiding the pin. It has a block and a cam follower arranged near the upper and lower traveling rails of the stacker crane of the rack body to guide the pins.

Further, the present invention provides a traverser stop positioning device having a function of releasing a stacker crane forcible stop device at an end of a vertical rail in a rack by sliding a pin on a traverser side.

In the present invention, the upper and lower traveling rails are forcibly centered by the action of a pin that slides the stop position of the traverser and a cam follower that guides the pin, and is stopped at a fixed point (stacker crane transfer position). Thereby, even if the stop position of the traverser fluctuates, it can be stopped at a fixed point (stacker crane transfer position).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the traverser stop positioning device according to the present invention will be described below in detail.

FIG. 1 shows an example of an automatic warehouse system to which the traverser stop positioning device of the present invention is applied, and FIG. 2 shows an example of a traverser to which the traverser stop positioning device of the present invention is applied.

As shown in FIG. 1, the automatic warehouse system comprises a stacker crane 1, a rack 2, and a traverser 3. The stacker crane 1 is guided by an upper traveling rail 4 and a lower traveling rail 5 and travels in the x direction. I do. The traverser 3 is guided by the upper travel rail 6 and the lower travel rail 7 and travels in the y direction. When the stacker crane 1 receives the load 8 and travels to the rail end, the traverser 3 stops along the traveling rails 4 and 5 of the stacker crane 1 in order to transfer the stacker crane 1. An upper traveling rail 9 for the stacker crane 1 is provided above and below the traverser 3,
A lower traveling rail 10 is disposed, and after the stacker crane 1 is guided by the rail and transferred to the traverser 3, the traverser 3 travels in the y direction.

Conventionally, in order to stop the traverser 3 at a fixed point (stacker crane 1 transfer position), the installation accuracy of the upper and lower traveling rails 6, 7 and the stacker crane 1, traverser 3
Manufacturing accuracy, traverser 3 stopping accuracy, running rail 6,
7, the manufacturing accuracy was improved. For this reason, as the level difference between the upper and lower traveling rails 6 and 7 becomes larger, the traveling rails 9 and 10 become larger.
Is technically difficult and costly.

In this embodiment, after the traveling brake of the traverser 3 is actuated and stopped, the upper and lower traveling rails 9 and 10 need to be centered in order to transfer the stacker crane 1 to the traverser 3 accurately and smoothly. It is necessary to slightly move the traverser 3 and the traveling brake of the traverser 3 is released. As shown in FIG. 2, a pin 11 having a sliding function is provided on the traverser 3 side, and a cam follower 12 for guiding the pin 11 is provided on the rack 2 side. When the pin 11 slides and is guided by the cam follower 12, the traverser 3 is forcibly moved slightly to the fixed point (the transfer position of the stacker crane 1), and the traveling brake is operated again. After this operation, the stacker crane 1 can be smoothly transferred from the upper and lower traveling rails 4 and 5 on the rack 2 to the upper and lower traveling rails 6 and 7 on the traverser 3.

[0013]

The traverser stop positioning device of the present invention forcibly centers the upper and lower traveling rails and stops at a fixed point by the action of a pin that slides the traverser stop position and a cam follower that guides the pin. Thus, even if the stop position of the traverser fluctuates, the traverser can be stopped at a fixed point (stacker crane 1 transfer position). According to the present invention, the manufacturing cost and reliability required for the conventional centering method for the upper and lower running rails having a large level difference between the rack side and the traverser side can be significantly modified.
