Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a telescopic conveyor, particularly a telescopic conveyor used for loading cargo into boxes or the like at a truck terminal of a transportation center.

(Prior art) As shown in Japanese Unexamined Patent Application Publication No. 513-13237, Taganhito previously introduced cargo shipped from a factory, etc. into a loading section and loaded it into a vehicle cargo box using a loading device. Load sequentially,
We are proposing a luggage transportation system.

This kind of luggage transport equipment requires a large amount of space,
Since this surface becomes a dead space unless loading work is performed, there has been a desire to make the entire device more compact.

By the way, the feed conveyor that connects the loading section of the device and the loading device is flexible.

When stored, the length is reduced to about half of the length when extended, but as vehicle cargo boxes (sea containers) become longer, the transport distance also tends to increase, which poses a bottleneck in making the entire device more compact. It had become.

In view of these points, a telescopic conveyor is known in which the length when stored is reduced to a fraction of the length when expanded (Japanese Patent Application Laid-Open No. 58-197104, No. Yusho), but the above-mentioned As described above, it was not possible to satisfy the contradictory condition of making the extension stroke thicker when the storage space was limited.

(Problems to be Solved by the Present Invention) The present invention has been made in view of the above points, and provides a telescopic conveyor that can be stored in an oak space and has a large telescopic stroke.

It consists of a leveler 53 connected to a movable trolley 50.
The four sub-wheels 52 can be operated in conjunction with each other, and the vehicle can run horizontally or diagonally, or perform spin turns.

By the way, the telescopic conveyor 24.41 has almost the same structure as shown in FIGS. 2 to 4, and has a large number of connecting rods 61 connected sequentially between the center and both ends. The elastic body 62 has a length of N11, and the legs 63 are arranged at appropriate intervals, and both ends of the connecting rod 61 are connected by 11N.

A conveying roller 64 is provided between the top end of the connecting rod 61.
However, transmission rollers 65 are arranged parallel to each other between the center portions of the rollers, with shafts attached at rotational positions.

Then, an endless body (belt) 66 is sequentially wound around the transmission roller 6571I and the transverse transport roller 64, and the motor 67 passes the endless body 66 and the transmission roller 65 to the transport roller 65.
are made to rotate in the same direction.

Here, the joining part between the lower end of the connecting rod 61 and the leg body 63 is as follows:
A sliding member 6 is fitted to the leg body 63 so as to be slidable downwardly.
It is pivoted through 3ae.

A pair of conveyance rollers 64 are also pivotally attached to the upper part of the biped body 63, and a rather short belt 66a is wound between the pair of conveyance rollers.

Further, the motor 67 is supported between one of the connecting rods 61a via a bracket drawer a, and its output shaft is located at the solid shaft end of the connecting rod connected in an X-shape. . A transmission roller 65 is fixed to the output shaft.

Furthermore, a downwardly inclined connection chute 68 is connected to the tip of the telescopic conveyor 24, and its lower end is positioned above the conveying roller 64 of the telescopic conveyor 41.

A dock leveler 53 is opposed to the rear opening of the waiting cargo box 2. The dog leveler 53 is appropriately raised and lowered to match the floor surface of the cargo box 2, and the traveling cart 45 is moved into the cargo box 2.

As the traveling trolley 45 enters the cargo box 2, the engaging member 69 fixed to the proximal leg of the telescopic conveyor 41 also engages the engaged member 68a of the connecting chute 68 from the lower inside of the telescopic conveyor 24. It is pulled forward until it engages. Thereafter, each of the X-shaped connecting rods 61, 61 of the telescopic conveyor 41 can change its rotation angle until the sliding member 63a abuts the stopper, thereby extending the length of the metal body.

Furthermore, when the telescopic conveyor 41 is fully extended, the engaging member 69 fixed to its base end leg engages with the engaged member 68a of the connecting chute 68, and the telescopic conveyor 24 also extends through the connecting chute 68. Meanwhile, the telescopic conveyor 24 is also extended.

At this time, since the distance between the conveyance roller 64 and the transmission roller 65flJi remains unchanged, both telescopic conveyors 24.41
When the motor 67 disposed at a proper position is rotated, all the conveying rollers 64 are rotated in the same direction.

On the other hand, the cargo l loaded by the carry-in conveyor 13 is stacked on the soil of the pallet l-12 and palletized, and is transported by a forklift or the like (not shown).

The luggage 1 stacked in stages by the WI input conveyor 13 is conveyed together with the pallet 12 to a depalletizer 16, where the luggage 1 is depalletized in each stage. The depalletized cargo l is placed in a tank on the delivery roller conveyor 21.
line up

Since the conveyance is carried out in a direction perpendicular to A 21, the articles 1 are conveyed in the direction in which they are lined up, and the 7 conveyor articles 1 are divided by this sending out;

The feeding conveyor 23 can be mounted on a mobile cart 5 with a small space.
It is bent in an S-shape in order to be mounted on the conveyor 23, and the attitude of the cargo l can be controlled by an attitude control device 30 provided in the middle of the feed conveyor 23.
