DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display for a digital picking stand, which is installed in a cold storage warehouse such as a refrigerator or a freezer at a distribution center and is used for sorting products for each store. Related to the evacuation device.

[0002]

2. Description of the Related Art Since the space where a digital picking stand is installed is usually in a cold storage warehouse, the display is evacuated when not in use and a forklift or the like enters an empty space from the viewpoint of effective use of the space. Other work may be performed.

However, in the conventional retracting device for the display, the holding member of the display is suspended by a wire or a chain, and is retracted vertically upward by using a hoisting crane or the like. However, this method requires an evacuation space above the digital picking gantry, and does not meet the demand for space saving. Further, there is a risk that the indicator may fall to the ground together with the holding member due to the breakage of the wire or the chain.

Further, in the conventional evacuation device, the holding member escapes when the push button attached to the indicator of the holding member is pressed by a human hand for hanging by a wire or a chain. It was necessary to reinforce it with guide rails or the like so as not to escape.

[0005]

The first problem is that the retracting device for the digital picking display is not retracted vertically but is retracted upward in the horizontal direction as a pivoting system around a support shaft. It is an object of the present invention to eliminate a necessary upper space and save space.

[0006] The second problem is that a wire or a chain is not used as a retracting device for a digital picking display, so that the retracting device is free from the risk of cut-off. There is no evacuation device.

[0007]

In order to solve the first problem, according to the present invention, a support shaft is provided near a retreat height position of a display, and a holding member of the display is rotatably mounted on the support shaft. A retraction device for a digital picking display, wherein the retraction device is mounted in a hanging manner and revolves and retracts a holding member to a position near a horizontal direction about a support shaft.

In order to solve the second problem, a rotary shaft rotated in one direction by a drive motor is provided near a retreat position of the display in parallel with a support shaft, and a rotary gear is mounted on the drive motor. The belt gear mounted on the holding member is meshed with the rotary gear on the opposite side, and the belt gear is pulled up by rotating the rotary gear to retract the holding member in the horizontal direction about the support shaft. A retraction device for a digital picking indicator according to claim 1 is provided.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention; FIG. 1 is a plan view of a digital picking stand, FIG. 2 is a front view thereof, and FIG. 3 is a side view thereof. In the present embodiment, the basic frame of the digital picking stand 1 is composed of three sets of horizontal frames 4 consisting of six columns 2 and two pairs connecting the columns 2 and a horizontal frame 4 to form a frame. And five vertical frames 3. The column 2, the vertical frame 3 and the horizontal frame 4 are provided at a position of about 3.2 meters above ground.

In the present embodiment, as shown in FIG. 1, eight lines of the holding members 6 of the display 7 are formed along the vertical frame 3. The holding member 6 is rotatably attached to the support shaft 5 so as to be rotatable. As shown in FIG. 7, the support shaft 5 is located below the two horizontal frames 4 (near the retracting position 12 of the display 7).
Are arranged in a line in a direction perpendicular to the horizontal frame 4.

The holding member 6 is a frame member made of an aluminum rail having a width of about 7 meters, and a lower end of the holding member 6 has a ground clearance of 1.7.
It is mounted so as to reach a position of 5 meters, and a display 7 is provided at the lower end of the holding member 6 as shown in FIG. That is, in the present invention, the support shaft 5 is fixed, the display 7 is hung from the support member 6 by the holding member 6, and the holding member 6 is rotated around the support shaft 5, and the display device 7 is retracted upward and horizontally. Let it do.

As shown in FIG. 4, a balance weight 13 which is positioned above the support shaft 5 in a hanging state is mounted on the holding member 6, and the holding member 6 is supported by a slight rotation torque. 5 is pivotable. Further, the holding member 6 is provided with a belt-shaped gear 11 which is curved in a substantially quarter circle arc shape. The band gear 11 is a spur gear,
This is a member for rotating the holding member 6.

As shown in FIG. 5, the rotating shaft 9 is parallel to the line of the support shaft 5 and is perpendicular to the horizontal frame 4 between the horizontal frames 4.
Is provided. The height and position of the rotating shaft 9 are displayed on the display 7.
Near the evacuation position 12. In the present embodiment, eight rotating shafts 9 are provided in accordance with the line configuration of the holding member 6, and a rotating gear 10, which is a spur gear, is mounted on the rotating shaft 9. The rotary gear 10 meshes with a band gear 11 fixed to the holding member 6.

Therefore, by rotating the rotary gear 10, the belt gear 11 is pulled up, and the holding member 6 on which the belt gear 11 is mounted is rotated and retracted around the support shaft 5 until it reaches the horizontal direction. Incidentally, reference numeral 14 in FIG. 6 denotes a rotary holder, and a V-groove pulley is used. The rear surface flat portion of the band gear 11 abuts on the V groove of the rotary retainer 14 and presses the meshing portion between the band gear 11 and the rotary gear 10 with the rotary retainer 14, so that the engagement of both gears is ensured. It will be.

The driving source of the rotating shaft 9 is a driving motor 8, and the rotating shaft 9 is rotated by one driving motor 8 per line. The belt-shaped gear 11 operated by one drive motor 8 reaches several places (three places in this embodiment). Therefore 1
Since it is possible to evacuate up and down for each line and to evacuate up and down in a short time, a space can be provided in the order in which the picking work has been completed, and the operation can be promptly shifted to work other than picking. The drive motor 8 has a brake function, and a rotation shaft 9 is directly connected to a motor shaft of the drive motor 8.

The drive motor 8 is stopped with the brake applied, except when the retraction device is operating.
The rotating shaft 9 and the rotating gear 10 attached to the motor shaft are in a state where the brake is always applied during the stop. Accordingly, since the band gear 11 meshing with the rotary gear 10 is also always in the braked state while stopped, when the push button attached to the display 7 is pressed, it becomes a resistance and the display 7 is attached. Thus, the holding member 6 also functions as a diagonal member in the escape direction.

Hereinafter, a method of using the present invention will be described.
When the drive motor 8 is driven, the rotating shaft 9 rotates, and the rotating gear 10 also rotates integrally. The curved belt-shaped gear 11 meshed with the rotary gear 10 is pulled up, and the holding member 6 with the indicator 7 is retracted from the position at a height of 1.75 meters above the ground to a position of 3 meters above the ground.

At 1.75 meters above the ground, the height is such that ordinary people can walk and pass below. However, when the height is 3 meters above the ground, forklifts and the like can pass.

[0019]

Since the present invention is configured as described above,
The following effects are exhibited. First, since the retracting device of the digital picking indicator is turned around the support shaft in the horizontal direction above, no space for evacuation is required, and space can be saved. Became possible. Therefore, the evacuation device can be installed even in an existing warehouse having a low ceiling height.

The second advantage is that no chain or wire is used to transmit the driving force of the retraction device, so that there is no fear of falling to the ground due to cutout. Was. In addition, even if an accident such as a fall occurs due to a failure of the evacuation device, a certain ground clearance is secured, so that there is no fear of damage to articles and personal injury.

Thirdly, the effect of claim 3 is that the difference in pitch circle diameter between the rotary gear mounted on the drive motor and the belt-shaped gear directly becomes the gear ratio, so that it operates with low torque (rotational force). Therefore, it can be operated by a drive motor having a small output, and energy can be saved. In addition, since the output of the drive motor can be reduced, noise during operation is small, and an alarm sound during operation, a danger avoidance signal by human voice, and the like can be heard well.

Fourthly, the effect of the embodiment is as follows. By rotating the rotating shaft by one drive motor per line and operating several rotating gears of each rotating shaft, a long holding is possible. The members can be retracted at once.

Fifth, similarly, the effect of the embodiment is as follows. One drive motor is provided for one line. However, there are several belt-shaped gears operated by the drive motor (3 in this embodiment).
Therefore, even in the event of an accident such as tooth spilling of a gear, safety can be ensured without immediately causing a situation such as dropping.
