Description

[Detailed Description of the Invention] The present invention relates to a conveyor device for carrying cargo into and out of loading beds of various trucks. Conventionally, belts and chains were connected in an endless manner and stretched over the loading platform.
There is a technique for pulling and moving a belt using a chain to load and unload cargo loaded onto the top surface of the belt. This belt is also supported by rollers and frames. In this case, since the chain also moves above the rollers or frame as the belt moves, oil from the chain adheres to these rollers or the frame, causing problems such as the belt slipping and meandering and contaminating the cargo. This is a particularly serious problem with frames developed to obtain an appropriate amount of frictional force between the belt and the belt.

The present invention solves the above-mentioned conventional drawbacks,
A belt and a chain are stretched on the loading platform, and a base frame is provided to slideably support both sides of the guiding frame stretched on both sides of the loading platform, and one end of the belt is connected to one end of the chain via a tension adjustment belt. The belt and chain are connected to the base frame, the other ends of these belts and chains are connected via a connecting member, and the belt and chain are stretched endlessly between a sprocket provided at the front end of the loading platform and a roller provided at the rear end of the loading platform, and In a structure in which a guide plate is stretched between the sprocket and the roller in the direction of movement of the belt and chain, and the belt is slidably moved on the upper surface of a plurality of convex sliding parts formed in parallel on this guide plate, the belt is moved between the convex sliding parts. While the upper surface side of the chain is stretched within this vertical width, a separably connected pallet is placed on the upper surface of the belt, and the belt sandwiched between the pallet and the plurality of convex sliding parts is slid. The chain is tensioned and moved between a plurality of convex sliding parts that slide the belt, thereby preventing oil from the chain from adhering to the upper surface of the convex sliding parts. Therefore, it is possible to appropriately move the belt during baggage conveyance without reducing the frictional force between the belt and the convex sliding portion and the digging of the convex sliding portion into the belt.
When transporting cargo by truck, the belt can be reliably kept stationary and safe cargo handling operations can be carried out. However, the present invention sandwiches the pallet, the convex sliding portion, and the belt, supports the belt on the top surface of the convex sliding portion, and moves the belt in sliding contact. By doing so, the weight of the baggage is distributed evenly to each convex sliding part, and the frictional force and biting amount between each of the convex sliding parts and the belt can be kept constant, which improves the straightness and movement of the belt when transporting the baggage. It is possible to reduce the load, improve the straightness of the belt and reduce the movement resistance when transporting goods by truck, and improve the stationary stability of the belt and increase the movement resistance when transporting goods by truck. It is an object of the present invention to provide a cargo handling conveyor device for trucks as described above.

An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 shows a box-shaped truck T having a driver's cab 1 and a box-shaped cargo compartment 2, with a part of the cargo compartment 2 cut away. A conveyor 4 according to the present invention is installed in the loading platform 3 of the cargo compartment 2, and the conveyor 4 is operated from the rear of the cargo compartment 2 via a conveyor drive device 6 driven by an engine 5 located below the cab 1. It is designed to be driven in a direction I to carry the baggage to the front or in a direction O to carry it out from the front to the rear. The conveyor drive device 6 includes a sprocket 7 provided in front of the conveyor 4, a traveling mission 8 of the engine 5, a reducer 9 including an electromagnetic clutch, etc., a bevel gear mechanism 10, and a drive shaft 11, respectively.

The sprockets 7, 15... of the conveyor 4 are rotated via the reducer 9, the drive shaft 12, and the bevel gear mechanism 10 to drive the chain 16, and the conveyor belt 18... of the conveyor 4 is rotated through the guide plate 21. Convex sliding portion 38... is driven in either the carry-out direction O or the carry-in direction I while sliding on the top. Therefore, when loading, for example, if the belt 18 is sequentially driven in the carry-in direction I for each pallet P, the worker does not have to repeatedly visit the cargo compartment from the rearmost part of the cargo compartment 2 to carry out the loading work, as in the past. If the blocks are loaded near the rear of the cargo compartment 2, and the conveyor 4 is driven in the carrying direction for each loaded block to sequentially store the blocks in the compartment, the conventional heavy labor is not required. When using the pallets P..., for example, they can be stacked or unloaded from below a truck connected to another conveyor (not shown) connected to the rear end of the conveyor 4 at the rear of the cargo hold 2. In this case, the tension Adjustment member 20

In a structure in which a guide plate 21 is stretched in the moving direction of the chain 16, and the belt 18 is slidably moved on the upper surface of a plurality of convex sliding portions 38 formed in parallel on this guide plate 21, between the convex sliding portions 38. While the upper surface side of the chain 16 is stretched within this vertical width, a separably connected pallet P is loaded on the upper surface of the belt 18, and the pallet P sandwiched between the pallet P and the plurality of convex sliding parts 38 is The pallet P is configured to be able to be put in and taken out by sliding the belt 18, and the chain is stretched between a plurality of convex sliding parts 38 that slide the belt, and by moving, a chain is formed on the upper surface of the convex sliding part 38. This prevents the oil from adhering to these belts 18.
The belt 18 can be moved appropriately during cargo transportation without reducing the frictional force between the convex sliding portion 38 and the convex sliding portion 38 biting into the belt 18. While the belt 18 can be reliably stationary and safe cargo handling operations can be carried out, the present invention has a structure in which the belt 18 is sandwiched between the pallet P, the convex sliding portion 38, and the belt 18, and the belt 18 is supported on the upper surface of the convex sliding portion 38. By slidingly moving the cargo, the weight of the cargo is evenly distributed to each of the convex sliding parts 38, and
8 and the belt 18 can be kept constant, the straightness of the belt 18 can be improved and the moving load can be reduced when carrying loads, and the belt 18 can be kept stationary when carrying loads by truck. This has remarkable effects such as improving performance and increasing movement resistance.
