Abstract

An article support device has a pair of support platforms arranged symmetrically and opposite to each other. Each of the support platforms includes a support frame, a support plate disposed on a top of the support frame and having a horizontal support top surface, and at least one positioning block installed on the horizontal support top surface. The horizontal support top surfaces of the support plates are located at a same height position. The article is supported on the horizontal support top surfaces and positioned between the positioning blocks on the support plates. An accommodation space is defined between the support plates and the support frames, and an automated guided vehicle moves into the accommodation space. An article carried on the article support device is loadable onto the automatic guided vehicle or the article carried on the automatic guided vehicle is unloadable onto the article support device.

First claim

What is claimed is:

1. An article support device assisting an automated guided vehicle to autonomously load and unload an article, comprising:
a pair of support platforms arranged symmetrically and opposite to each other, each of the support platforms including:
a support frame;
a support plate disposed on a top of the support frame and having a horizontal support top surface, the support plates opposed to and spaced apart from each other in a left-and-right direction; and
at least one positioning block installed on the horizontal support top surface, including:
a pair of opposite sides in the left-and-right direction and a pair of opposite ends in a front-and-back direction;
a vertical positioning side surface on each of the pair of opposite sides, the vertical positioning side surface adapted to contact a side surface of the article so as to position the article between the positioning blocks on the support plates;
a first guide slant face perpendicular to the horizontal support top surface formed at either side of each end of the positioning block; and
a second guide slant face inclined with respect to the horizontal support top surface formed on an upper portion at either side of a middle part of the positioning block and located above the vertical positioning side surface, the upper portion of the middle part of the positioning block has a width gradually increasing downward from a top surface, a vertical flared mouth is defined between the second guide slant faces, arranged to face each other, of the two positioning blocks opposite to each other in the left-and-right direction, so as to correctly guide the article moved vertically into a space between the positioning blocks, the horizontal support top surfaces of the two support plates are located at a same height position, the support device adapted to support the article on the horizontal support top surfaces and positioned between the positioning blocks on the two support plates; and

an accommodation space defined between the support plates and the support frames of the pair of support platforms, the accommodation space adapted such that as the automated guided vehicle moves into the accommodation space, the article carried on the article support device is loadable onto the automatic guided vehicle or the article carried on the automatic guided vehicle is unloadable onto the article support device.

2. The article support device of claim 1 , wherein each end of the positioning block has a width gradually decreasing from a base to a tip.

3. The article support device of claim 2 , wherein a horizontal flared mouth is defined between the first guide slant faces, which are arranged to face each other, of the positioning blocks opposite to each other in the left-and-right direction, so as to correctly guide the article moved horizontally into a space between the positioning blocks.

4. The article support device of claim 1 , wherein a second guide slant face inclined with respect to the horizontal support top surface is formed on an upper portion at either side of a middle part of the positioning block and located above the vertical positioning side surface, the upper portion of the middle part of the positioning block has a width gradually increasing downward from a top surface.

5. The article support device of claim 4 , wherein a vertical flared mouth is defined between the second guide slant faces, arranged to face each other, of the two positioning blocks opposite to each other in the left-and-right direction, so as to correctly guide the article moved vertically into a space between the positioning blocks.

6. The article support device of claim 1 , wherein the positioning block has a strip-shaped installation groove extending in the left-and-right direction, the positioning block is fastenable to the support plate by a screw connection passing through the strip-shaped installation groove.

7. The article support device of claim 6 , wherein the strip-shaped installation groove extends by a predetermined length in the left-and-right direction such that the positioning block is allowed to move by a predetermined distance in the-left-and-right direction when the screw connection is loosened, a spacing distance between the positioning blocks is adjustable to match a size of the article.

8. The article support device of claim 1 , wherein each of the support platforms has a positioning plate installed on the support frame and located inside the accommodation space, the positioning plate having a vertical positioning surface perpendicular to the left-and-right direction.

9. The article support device of claim 1 , wherein the support frame is fixed on a ground or on a fixed base so that the article support device is immovable.

10. The article support device of claim 1 , further comprising a connection piece connected between rear ends of the support frames and a plurality of rollers installed at a bottom portion of each of the support frames, the article support device is movable by the rollers.

11. The article support device of claim 10 , further comprising a handle connected to the rear ends of the support frames, the article support device is drivable to move on a ground by pushing or pulling the handle.

12. The article support device of claim 10 , wherein the rollers include a pair of universal rollers installed at bottom portions of front ends of the support frames and rotatable about a vertical axis and a horizontal axis, and a pair of fixed rollers installed at bottom portions of the rear ends of the support frames and rotatable about a horizontal axis.

13. The article support device of claim 1 , wherein each of the support platforms has a pair of positioning blocks, one of which is arranged on a top surface of a front end of the support plate and the other of which is arranged on the top surface of a rear end of the support plate.

14. An article loading and unloading system, comprising:
an automatic guided vehicle having a rangefinder; and
an article support device assisting the automated guided vehicle to autonomously load and unload an article, the article support device including:
a pair of support platforms arranged symmetrically and opposite to each other, each of the support platforms having:
a support frame;
a support plate disposed on a top of the support frame and having a horizontal support top surface;
at least one positioning block installed on the horizontal support top surface, the horizontal support top surfaces of the two support plates are located at a same height position, the article is supported on the horizontal support top surfaces and positioned between the positioning blocks on the two support plates; and
a positioning plate installed on the support frame and located inside the accommodation space, the positioning plate having a vertical positioning surface perpendicular to a left-and-right direction; and

an accommodation space defined between the support plates and the support frames of the pair of support platforms, the automated guided vehicle moves into the accommodation space, the article carried on the article support device is loadable onto the automatic guided vehicle or the article carried on the automatic guided vehicle is unloadable onto the article support device, the rangefinder of the automatic guided vehicle adapted to detect a distance between left and right sides of the automatic guided vehicle and the vertical positioning surfaces of the positioning plates located opposite to each other in the left-and-right direction to determine a position of the automatic guided vehicle relative to the positioning plates and correctly guide the aut
