It relates to a garbage packing unit of the waste injector for automatic waste collection system that can prevent the leakage to the outside to transport the waste more stably.

The automatic garbage collection system is a facility that transfers garbage sucked with air by the suction power of a blower to a storage facility through a transport pipeline.In particular, unlike conventional collection methods by personnel and vehicles, household wastes are collected indoors. If the waste is thrown out at an outdoor waste inlet, it is transported to the central collection facility along with the high-speed air (approximately 70 ~ 90km / h) flowing through the transport pipeline under the control of the central control system, and is directly put into the incinerator according to the type of waste. Refers to a facility that automatically loads containers into final processing plants.

The automatic garbage collection system solves the odor and hygiene problems caused by the above-mentioned conventional collection method, creates a pleasant living environment, solves pollution and safety problems of the collected vehicles, and improves the city with an eco-friendly image, unnecessary resources and It prevents waste of energy, reduces the operation and management costs of residents with unmanned system, and economic effect of consolidating the local government's finances by the need of collecting personnel and vehicle operation, and odor, leachate, damage caused by animals, etc. The hygienic effect to prevent this is expected.

Therefore, a lot of automatic garbage collection systems have been introduced not only in apartments that are recently constructed but also in hospitals, large restaurants, high-rise buildings, and airports.

Accordingly, although the inlet and the storage chute are separated to separate and separate the general waste and food waste, the transport pipe for transporting the waste by suction is composed of one.

Accordingly, food waste and general waste are moved together in the conventional transport pipeline, but in the past, the food waste is transported as general waste while being contained in a pay-as-you-go bag. In the transport pipeline, the waste can be moved at a high speed of about 25 m / s. As it travels about 2 ~ 3km, the payload bag containing food waste (it is made of biodegradable resin and weak in durability) could fly off at high speed.

In particular, when the curvature of the transport pipeline is curved, the payload envelope containing the food waste hits the inner wall of the transport pipeline at the point where the curvature changes, and the food waste is attached and messed up. The hassle of tying and sealing the upper part to prevent leakage and the inconvenience of getting food waste on the hands occurred in the process.

It is an object of the present invention to increase the packing strength by additionally packing and packing waste using a packing bag, thereby preventing garbage from leaking to the outside of the packing bag during transportation of the transport pipe, which can automatically transport the waste more stably.
