Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conveying device, and its purpose is to be able to smoothly and speedily perform the work of stacking cargo high in a warehouse or loading and unloading cargo. Or, even when the loading and unloading position moves up and down, the loading and unloading position at the base end of the telescopic conveyor does not change, maintains the fixed position, and improves work efficiency.Moreover, there is a hoist that can raise and lower the underframe. It is an object of the present invention to provide a highly safe conveyance device that can reliably prevent the danger of the underframe automatically engaging and stopping the support support and falling when the means is damaged.

Today, in agricultural warehouses, bags containing rice, wheat, etc. (burlap bags, paper bags, resin bags, etc.) are piled up using various conveyors that are arranged in series from outside the warehouse to the co-loading area inside the warehouse. ing.

However, in the past, when bales were used as storage bags for rice, wheat, etc., the bales maintained a certain shape regardless of the contents, so if they were not stacked properly, they would tend to fall apart. There was little danger.

However, recently, the bales have been replaced by jute bags. Bags such as paper bags and plastic bags have come into use, but these bags change shapes depending on the flow of their contents, and as a result, there is a risk of them collapsing in the event of an earthquake, etc. .

Therefore, in recent agricultural warehouses, in order to prevent the warehouse from collapsing, a framework is constructed using scaffolding pipes for construction, etc., and horizontal supports are installed between each framework. It is constructed with means to prevent it from collapsing.

However, when a framework is set up in a warehouse as described above, horizontal supports are hung horizontally over the aisles, so it is no longer possible to arrange a portable conveyor for transportation inside the warehouse and move it back and forth and up and down, as in the past. This may cause inconvenience such as hindrance to transportation work. This will cause problems.

Therefore, the present applicant proposed Japanese Patent Application No. 53-120619 (Japanese Unexamined Patent Publication No. 55-481) to solve such problems.
We have already proposed a conveyance device as shown in No. 22),
This device uses a rotating turntable and a scraper placed on the turntable to transport the cargo out of the turntable, so the weight of the cargo is heavy.
Moreover, if the bag is made of resin, slipping occurs between the scraper and the baggage, causing problems such as the baggage being left on the turntable and not being carried out.

In addition, one end of the inclined conveyor is pivotally supported by the plywood that moves up and down along the pillar, so as the plywood moves up and down, the other end of the inclined conveyor, that is, the loading position, moves in the left-right direction. It is.

Therefore, if the plywood is moved upward as the stacking height increases, the working position at the base end of the inclined conveyor will also move, and the moved portion must be carried by a person or another conveyor must be connected. First, it lacks workability.

Therefore, the present invention has been made to solve the above-mentioned problems and inconveniences.The present invention has been made in order to solve the problems and inconveniences described above. At the same time, a warehousing slat conveyor is rotatably mounted on the turn slat conveyor, and one end of the telescoping conveyor is pivotally supported on the underframe so as to be able to swing vertically. The side end can be connected to the above-mentioned warehousing conveyor or turn slat conveyor, and the underframe is further provided with a safety mechanism that automatically engages the underframe with the support if the suspension means is damaged. It is characterized by this.
