Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to abandoned home appliances, abandoned office equipment,
The present invention relates to the unloading of loads that have been mixed-loaded by trucks, etc., targeting the recycling processing equipment of abandoned vehicles.

[0002]

2. Description of the Related Art Waste electric home appliances, etc. brought in by mixed loading by truck are lifted one by one with a hoist or the like to be unloaded to a stockyard. In addition, the unloaded cargo is again lifted and supplied to the processing facility.

As another example, Japanese Utility Model Laid-Open No. Sho 63-183130 discloses a technique for carrying and unloading waste home electric appliances and the like by means of a dedicated truck having a carrying conveyor mounted on a carrier.

[0004]

As the amount of general waste such as oversized waste discharged from general households and offices, or industrial waste discharged from offices increases, a treatment facility for it ( Recycling facilities) and trucks are required to have a higher operating rate, but at least two people are required for the current unloading work, and unloading is carried out one by one. Since the time and the staying time of the truck are long, the efficiency is poor, and the load supply to the next process is unstable, so that stable processing capacity as a whole cannot be expected. Furthermore, no consideration is given to the unloading of trucks with different heights of the loading platform and the smooth movement of loads within the loading platform.

Further, although the above-mentioned drawbacks are somewhat improved in the unloading disclosed in Japanese Utility Model Laid-Open No. Sho 63-183130, a general collection truck is used because a dedicated truck equipped with a conveyor for transportation is required. On the other hand, on the other hand, the amount of waste home electric appliances and the like is enormous, so that an extremely large number of dedicated trucks are required to cope with this enormous amount, which is unrealistic.

It is an object of the present invention to automate the unloading work from a truck and to efficiently unload a large amount of loads brought in at one time in order to improve or not reduce the processing capacity of the entire processing facility. . It is also a system that eliminates the originally required stockyard and automatically supplies it to the processing facility for the next process from the time of unloading.

[0007]

A feature of the present invention is to shorten the unloading time by unloading a load brought in by mixed loading from a truck onto an unloader conveyor at once by a load transfer device. .

The feature of the present invention is that the load transfer device forcibly unloads the cargo. Therefore, by laying a dedicated sheet on the loading platform of the truck in advance, the loads loaded by the mixed loading are not forced. It is possible to slide on the seat and to unload the truck bed without damaging it.

A feature of the present invention is that an unloader conveyor is installed in the unloading space to immediately supply the transfer conveyor to the transfer conveyor after the unloading from the truck, so that the loads brought into the processing facility can be sequentially transferred to the processing facility. Supplying and reducing the processing hold period of the cargo.

A feature of the present invention is that the load is transferred diagonally upward when it is supplied to the processing facility by the transfer conveyor, and a step is provided on the conveyor to prevent the transfer of the load in an overlapped state that occurs when the load is unloaded. , It is to provide a stable supply to the processing facility of the next process.

[0011]

The waste household electric appliances and the like to be treated according to the present invention are brought to a treatment facility or the like by a truck having a dedicated sheet laid on a loading platform and unloaded by the apparatus according to the present invention. The truck loaded with the objects to be processed is first parked in a designated parking area so that it can be unloaded. After that, the object is transferred onto the unloader conveyor so as to slide on the sheet of the truck bed by the automatic unloading device. The transferred object is automatically supplied to the transfer conveyor and the inclined conveyor by an unloader conveyor according to the supply amount according to the processing capacity of the processing facility of the next process. Double transfer or adjacent transfer of the object to be processed is prevented by using the step at the front stage and the rear stage of the inclined conveyor while transferring the object to be processed by the transfer conveyor and the inclined conveyor. Through these steps, the objects to be processed are spaced from each other, and stable automatic supply to the processing facility of the next step can be performed.

[0012]

An embodiment of the present invention will be described with reference to the drawings. 1 and 2 are respectively a front view and a plan view showing an embodiment of the automatic unloading device according to the present invention. The automatic unloading device comprises an automatic unloading device 1, an unloader conveyor 4 in which a truck unloader, a conveyor, and a cargo collapse guard are combined, a transfer conveyor 5, and an inclined conveyor 6.

As shown in FIG. 3, the automatic unloading device includes a pair of gate-shaped columns 11 and 12, traveling bodies 13 and 14 that travel on the girders 11a and 12a of the gate-shaped columns 11 and 12, and a traveling body 13. , 14 and the pushing body 15 that moves as the vehicle travels. The traveling of the traveling bodies 13, 14 is performed by a control signal from the system control unit. As shown in FIG. 2, the unloader conveyor 4 is provided on both end sides of the gate columns 11 and 12.
Is installed, and a truck can be stopped horizontally with the center of the gate-shaped columns 11 and 12. Objects 3 to be treated such as waste home electric appliances are stacked on the bed of the truck 2 via a sheet, and in this truck, the pushing body 15 is on one end side of the gate columns 11 and 12 (see FIGS. 2 and 3). The left side), the other end side (Fig. 2,
It is horizontally attached to the unloader conveyor 4 (on the right side of FIG. 3).

After the truck 2 is mounted horizontally, the traveling bodies 13, 14
The object 3 on the loading platform of the truck 2 slides on the sheet laid on the loading platform and is moved to the unloader conveyor 4 by moving the pushing body 15 by moving the.

Since the truck 2 to be used is assumed to be a general-purpose truck, in order to keep the height of the loading platform of the truck 2 and the height of the unloader conveyor 4 parallel, the lifter function of the unloader conveyor 4 adjusts the vertical height. To do. Also,
The unloader conveyor 4 prevents a load collapse expected when it is transferred by the load collapse guards 7 on both sides of the unloader conveyor.

The unloader conveyor 4 is, for example, as shown in FIG. 2, a pedestal 41 and a conveyor 42 that can move up and down on the pedestal 41.
And the conveyor 42 is orthogonal to the transfer conveyor 5.
Therefore, the workpiece 3 transferred from the loading platform to the conveyor 42 is sent to the transfer conveyor 5.

The transferred object 3 is supplied to the next transfer conveyor 5 by the conveyor function of the unloader conveyor 4, and the transfer speed at this time is adjusted to the processing capacity of the processing facility for the next step, Controllable.

The object 3 to be processed is transferred from the transfer conveyor 5 to the inclined conveyor 7, and the object 3 is intentionally dropped while utilizing the step between the front and rear of the inclined conveyor 7 during transfer. Double transfer of the object 3 or adjacent transfer is prevented.

Through these steps, the objects 3 to be processed can be spaced from each other and a stable automatic supply to the processing facility of the next step can be performed.
