Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a truck loader suitable for loading bags on a truck.

Various types of machines have been known for loading bulk goods onto trucks, but there is no dedicated machine for loading bags of any size onto trucks, and the only way to do this is by hand, making cargo handling extremely inefficient. Met.

This invention was made with the aim of improving the current state of cargo handling operations and streamlining the cargo handling operations.

Embodiments of the present invention will be described in detail below based on the drawings.

In FIGS. 1 to 3, reference numeral 1 denotes a support girder installed over a loading port provided on a floor 2 of a warehouse or the like,
It has a supply conveyor 3 for conveying bags on its top surface, and a scraper 4 for scraping the bags conveyed by this supply conveyor 3 onto a loader, and on its side, it has a loader frame 5 supported so as to be able to rise and fall, and the loader frame. A loader is provided which includes a vertical vertical belt conveyor 6 suspended inside the belt, a direction change chute 7 attached to the lower end of the belt conveyor 6, and a shirt torque conveyor 8 attached to the lower end of the loader frame 5. .

The support girder 1 may be a fixed type as shown in the figure, or it may be supported so as to be able to run on a rail 10 laid on the floor surface 2 via wheels 9 provided at both ends, as shown in FIG. It may also be a traveling type.

In the case of a fixed type, the loader frame 5 is attached as shown in Figure 5.
The pinion 1 is directly connected to the drive motor 11 and is installed on the loader frame 5 with a support structure that allows the lower end to be moved around.
2 and a gear 13 formed on the outer periphery of the lower swing-side frame 5'.

The rotating side frame 5' corresponds to the support portion of the shuttle conveyor 8 in FIGS. 1 and 3.

Therefore, when the swing side flap 5' turns, the position/direction changing shot shuttle conveyor 8 turns under it.

In addition, when the support frame 1 is configured as a fixed type as described above, both the loader frame 5 and the swing side frame 5', which is the support part of the shuttle conveyor 8, shown in FIGS. 1 to 3 are cut in cross section. Form into a circular shape.

This can also be applied directly to a traveling support girder.

The lifting and lowering of the loader frame 5 supported on the support girder 1 is as follows:
Appropriate well-known technical means such as a pin rack (not shown) attached to the outer surface of the loader frame 5 and a pinion 1 directly connected to a drive motor (not shown) installed on the support girder 1.
It is moved up and down by the engagement with 4.

The clamp-type vertical belt conveyor 6 includes a supporting side vertical belt conveyor 6a that is wound around groove wheels 15 and 16 installed vertically above and below inside the loader frame 5, and a supporting side vertical belt conveyor 6a that is wound around groove wheels 15 and 16 that are installed vertically inside the loader frame 5, and a support side vertical belt conveyor 6a that is wound around groove wheels 17 to 23 that are opposite to this. A downward conveyance path A is formed between the suppressing side vertical belt conveyor 6b and the vertical belt conveyor 6b with its end facing downward from the supply conveyor 3. As shown in FIG. 6, the belt facing the belt is held by a large number of roller groups 24 arranged between the groove wheels 15, 16 and 17, 18 to prevent the belt from slackening. The spring 25 that presses the roll group 24 presses the suppression side belt toward the downward transfer path A.
In the one vertical belt conveyor 6b, the upper part of the forward belt is supported by fixed groove wheels 18 and 19 located below the discharge of the supply belt conveyor 3, and the return belt part is moved in response to the vertical movement of the loader frame 5. It is supported by a tension groove wheel 21.

Therefore, even when the loader frame 5 is moved up and down, the positional relationship between the supply conveyor 3 and one of the vertical belt conveyors 6b and the belt tension are always kept constant, and even when the loader frame 5 is moved up and down, There's no need.

In the shirt torque conveyor 8, a movable frame 27 is slidably inserted into a frame 26 attached to the lower end of the loader frame 5, and groove wheels 28 and 29 are provided on the movable frame 27.
A shirt conveyor 8 is stretched over the conveyor belt.

The movable frame 27 is force-supported by wheels (not shown), and the movable frame 27 is moved by a large pin rack or a rope trolley set, and the movable frame 27 is powered manually or by a drive. Motors etc. are used.

Reference numeral 30 designates a bag loading belt conveyor installed in the warehouse, the tip or side end of which faces the support girder 1 soil supply conveyor 3, and a scraper 31 and a chute 32 for transferring transported goods are installed as needed. provided.

33 is a truck passage built under the floor of a warehouse or the like, and 34 is a truck.

In order to load the bags accumulated in the warehouse into the trunk using the truck loader configured as described above, the truck path 3
The truck 34 introduced in step 3 is placed directly below the shirttle conveyor 8 of the loader, and the loading position is adjusted by vertically adjusting the loader frame 5 and moving the shirttle conveyor 8.
The belt conveyor 30, the supply conveyor 3, the pinch-type vertical belt conveyor 6, and the shirt conveyor 8 are rotationally driven.

When the worker places the bag B on the belt conveyor 30, the bag B moves in the direction of the arrow, is transferred to the supply conveyor 3 facing the belt conveyor 30, and is picked up by the scraper 4 provided at its discharge section. It is fed into a type vertical belt conveyor 6.

Bags B are fed into the belt conveyor 6 using a vertical clamping system.
Further, the belt moves downwardly in the descending transfer path A by the belt which is clamped by the belt pressed by the pressing force of the spring 25 and rotates.
The shirts are delivered to the shirttle conveyor 8 by the direction change chute 7, and then sequentially stacked onto the truck 34 from the discharge end by rotation of the shirttle conveyor 8.

In this case, as the loading of the bags B progresses, the loader frame 5 and the shirt conveyor 8 are moved and adjusted as appropriate to continuously carry out the truck loading operation.

As described above, according to the present invention, even when the loader frame is moved up and down, the positional relationship between the supply conveyor and the pinch-type vertical conveyor is always maintained constant, so that bags can be transported from warehouses or bag storage yards, etc. can be efficiently loaded onto a variety of trucks of different sizes and heights, especially those using the rotating shirt torque conveyor 8. It can also improve loading ability.

′! ! Adopting a traveling type support girder has the advantage of making it possible to efficiently load a large number of trucks arranged in parallel.
