[Detailed Description of the Invention] (Industrial Field of Application) This invention relates to a hanging basket for transporting articles installed in an overhead type article conveying device or the like.

(Prior Art) Conventionally, the following are known as article conveyance devices for conveying articles that have been conveyed to the front end of an article conveyance roller conveyor provided on the ground.
That is, there is an elevating frame provided above the front end of the article conveying roller converter so that it can be horizontally moved and raised and lowered, and a roller that is provided on this elevating frame so as to be able to move horizontally in a direction parallel to the axis of the roller. A device is known that has a plurality of forks that enter the forks and a press plate that is vertically movable and is provided on the elevator frame so as to be located above the forks (see Japanese Patent Laid-Open No. 130824/1983).

(Disadvantages of the Prior Art) The conventional article conveyance device has the following disadvantages. That is, since the article was clamped and held by a fork and a pressing plate, there was a drawback that if the clamping force was weak, the article would fall. Also,
If the article is easily deformed, such as a cardboard box, the article may be deformed by the pressing force of the pressing plate during transportation, and the deformation may cause the clamping force from above and below to be applied to the article. When the size is small, there is a drawback that the item may fall.

(Purpose of the invention) This invention was made in order to eliminate the above-mentioned drawbacks, and provides a hanging basket for transporting goods that can reliably transport goods, especially easily deformable goods such as cardboard boxes. The purpose is to

(Example) This invention will be described below based on an example shown in the drawings. In this specification, the front refers to the right side in Figure 1, the rear refers to the left side in the same figure, and the left refers to the second
The left side of the figure refers to the right side of the figure, and the right side refers to the right side of the figure.

As shown in FIG. 1, an article conveying roller conveyor 2 is provided on a floor surface 1.

Rollers 4 are rotatably provided at predetermined intervals, and these rollers 4 are rotated by a drive device (not shown). The envelope surface of the upper end of the group of these rollers 4 serves as a conveyance surface 5. In front of the foremost roller 4 of the roller conveyor 2, a stopper 6 that does not or does not move up and down is provided.

A guide rail 13 is provided on the ceiling 11 via a hanging fixture 12 so as to pass above the front part 7 of the roller conveyor 2.
A traveling vehicle 14 is suspended movably along the traveling vehicle 14, and an elevating frame 15 is provided on the traveling vehicle 14 so as to be movable up and down by an elevator 16. have.

The lifting frame 15 is provided with an article support frame 20 having an article loading port 19 at the front and rear. Support frame 21
These support frames 21 include left and right vertical bars 22 that fit between the side walls 3, and horizontal horizontal bars 23 that fit between the rollers 4 that are connected to the lower ends of these vertical bars 22. have. A light projector 26 of a photoelectric switch 25 is mounted on one of the vertical bars 22 of the support frame 21.
However, a light receiver 27 is provided on the other side, and these photoelectric switches 25 determine whether the article W has completely entered the article support frame 20 or whether the article W has entered the article support frame 20.
On the other hand, you can tell if it has come out completely. That is,
When all the light receivers 27 change from the light receiving state to a state where the light beams reaching all the light receivers 27 are blocked by the article W, it can be known that the article W has completely entered the article support frame 20, When the opposite state change occurs, it can be known that the article W has completely come out from the article support frame 20.

At the front and back of the article support frame 20, a front-rear position regulating frame 29 is provided on the elevating frame 15 with the following structure so as to move back and forth in mutually opposite directions in synchronization. That is, a pair of left and right guide rods 33 are provided at the front and rear of the elevating plate 15, a slider 34 is provided on each of the front and rear guide rods 33 so as to be movable back and forth, and a longitudinal position regulating frame 29 is attached to these sliders 34. It is being The slider 34 has a screw hole 3 with its axis parallel to the axis of the guide rod 33.
5 are formed, screw shafts 36 are screwed into these screw holes 35, these screw shafts 36 are rotatably supported by the lifting frame 15, and bevel gears 37 are formed at mutually opposing ends of these screw shafts 36. A driving bevel gear 38 is engaged with these bevel gears 37, and this driving bevel gear 38 is fitted onto a rotating shaft 40 of a motor 39 provided on the elevating frame 15. With this configuration, the sliders 34 (front-back position regulation 29) are moved toward or away from each other by rotation of the screw shaft 36. The longitudinal position regulating frame 29 is connected to a horizontal support bar 30 fixed to the slider 34 and to the left and right ends of the horizontal support bar 30 in a hanging manner.
It has left and right vertical bars 31 that fit between the side walls 3, and a horizontal horizontal bar 32 that fits between the rollers 4 and is connected to the lower ends of these vertical bars 31. The upper edge of this horizontal horizontal bar 32 is the horizontal horizontal bar 2 of the article support frame 20.
It is positioned above that of No. 3. A light emitter 43 of a photoelectric switch 42 is provided on one side of the vertical beam 31 of the longitudinal position regulating frame 29, and a light receiver 44 is provided on the other side. You can know when you are in contact. That is, when the front and rear light receivers 44 change from a light-receiving state to a state in which the light beams reaching these light receivers 44 are blocked by the article W, it is known that both the front and rear front-back position regulating frames 29 have come into contact with the article W. I can do it.

(Effect of Example) Next, the operation of the embodiment device will be explained.

When the article support frame 20 becomes empty, the traveling vehicle 14
Moves to above the front part 7 of the article conveyance roller conveyor 2, and the front longitudinal position regulating frame 29 touches the stopper 6.
, and each support frame 21 is located in front of the roller 4
It will stop when it is located directly above the space between. Note that the front-rear position regulating frame 29 is open and leaves a space between it and the front and rear support frames 21 that is equal to the mounting pitch of the roller 4. Thereafter, the elevating frame 15 starts to descend, and when the horizontal horizontal bar 23 of the support frame 21 and the horizontal horizontal bar 32 of the rear longitudinal position regulating frame 29 are located below the conveying surface 5 that fits between the rollers 4. Stop. After that, the article W is conveyed to the front part 7 by the article conveyance roller conveyor 2, but since the horizontal horizontal bars 23 and 32 are located below the conveyance surface 5, the article W hits the stopper 6. It is transported to a certain position and stopped there. In this state, the rear end of the article W is not positioned above the horizontal horizontal bar 32 of the rear longitudinal position regulating frame 29.
Next, since the elevating plate 15 rises, the article W is scooped up by the horizontal crosspiece 23. Then, when the elevator frame 15 rises to the highest position, or on the way, the longitudinal position regulating frames 29 come together, and even after the article W comes into contact with either one of the horizontal horizontal bars 32 of the longitudinal position regulating frame 29. , both the front and rear position regulating frames 29 further come together, so that the article W is moved by the horizontal horizontal bars 32 until the article W comes into contact with the other horizontal horizontal bar 32, and both horizontal bars 32 are moved against the article W. When it comes in contact with the photoelectric switch 42,
This can be determined by the fact that both of the light receivers 44 no longer receive light. ), the longitudinal position regulating frame 29 stops, and in this state, the article W does not move in the longitudinal direction. Thereafter, the traveling vehicle 14 starts traveling and travels to the unloading station, where it is unloaded onto a roller conveyor having the same structure as the article conveyance roller conveyor 2 by an operation reverse to that described above.

(Effects of the invention) This invention has the following effects due to the above-described configuration.

Since the article is scooped up using the support frame, it is possible to reliably transport the article without dropping it.

Since the article is not held between the top and bottom, even easily deformable articles such as cardboard boxes can be reliably transported without being deformed.

Since the front-back position of the article is regulated by the front-back position regulating frame that moves back and forth in opposite directions in synchronization, the front-back position can be reliably regulated even if the sizes of the articles are different. It is possible to safely transport goods by doing so.
