DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a labor-saving truck unloading apparatus and method.

[0002]

2. Description of the Related Art In a conventional chip unloading method, a truck in which chips are stacked in bulk is tilted backward by a truck damper facility, slipped into a chip bin, transferred to the next process by a conveyor, and made into a product. FIG. 5 shows the outline of the truck damper equipment. A truck 20 in which chips are piled up is a container 21 without a top plate, and the rear portion is tilted upward so that the entire vehicle body is inclined and the chips are dropped. It is made exclusively for chip transportation with a door 22 and is called a chip car.

The truck damper equipment includes a platform 3, a hydraulic device 4, a cylinder 23, an overpan 1, a tip bin 5, and a weighing device 11. The platform 3 is driven by the hydraulic device 4 and the cylinder 23,
The tip car is tilted to a maximum of 55 degrees for unloading. It is framed by shaped steel and steel plate, has sufficient width and strength for the unloading of the tip car, and has a tip car at one end when the platform 3 is inclined. A backstop 2 using a rigid section steel for supporting the vehicle is mounted. A weighing device 11 for measuring the load capacity is installed below the platform 3, and is connected to an arithmetic unit 12, and the measurement result is output to a printer 13.

[0004] A chip bin 5 is provided below the overpan 1, and a tipping car passes over the overpan 1, and when unloading the chips, the overpan 1 is opened by a double door opening method. An operation panel for operating the overpan 1, the backstop 2, and the platform 3 is provided at a position in the operation room where the entire truck damper facility can be seen.
In a conventional unloading operation of a chip car such as a wood chip, a worker for operating the back stopper 2 and the overpan 1 of the truck damper device is always on standby in addition to the driver of the chip car.

[0005] The procedure of unloading the tip car is as follows: The tip car enters the truck damper device at the signal of the worker. After confirming that the tipping vehicle has stopped at the fixed position on the overpan, the worker raises the backstop and simultaneously releases the overpan. After confirming the rise of the backstop, the chip driver
After retracting the truck to the backstop and making it adhere,
The tipper driver gets off the tipper, registers the card in the operation room, and measures the total weight of the tipper. The driver raises the damper and starts unloading, and the operator holds a sample box and stands by at a sampling port, and collects the sample transported by the sampling conveyor. After unloading is completed, the driver lowers the damper, measures the weight of the empty vehicle, receives a receipt, and completes the unloading operation. The chip car that has completed unloading exits from the truck damper device. The worker confirms that the tipping vehicle has exited the truck damper device, lowers the backstop and closes the overpan, and waits for the next tipping vehicle to enter the truck damper device.

[0006] In a series of operations, if the next chip vehicle enters with the overpan open, there is a risk of falling into the receiving bin. In addition, if the backstop ascending position is not appropriate, the backstop will fall and become a serious disaster, and the receiving work will be stopped for a long time, resulting in a large loss in driving. Therefore, receiving work by one person was dangerous because of the danger of accident. On the other hand, when the operator of the device was absent or outside the working hours of the operator, the driver of the chip car could not unload and was inefficient.
