Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is useful for collecting empty cans such as canned juice.
This is related to an empty can collection truck with a small empty can press mounted on the loading platform (prior technology). There are roll-type small manual presses, pressure plate-type small hydraulic presses, hammer-equipped small electric presses, fully automatic large hydraulic presses, etc. Among these various presses, there are especially small presses exclusively for empty cans. It is only helpful to prevent empty can pollution if they are installed individually at the sales and consumption points of canned juice, etc. However, in the current situation where vending machines are overflowing, installing them at individual sales points is costly and expensive. This is practically impossible in terms of management.

On the other hand, while large hydraulic press machines are suitable for processing large quantities of empty cans collected in one place, they are difficult to transport when collecting empty cans by truck, etc. In other words, the apparent volume of empty cans is The actual weight ratio of the cans to the actual cans was extremely small, making it unprofitable to collect empty cans.In addition, some of the empty cans collected were not only safe, such as juice cans, but also contained pesticides. ,cosmetics.

Cases in which there is a risk of explosion (7), such as paint spray cans that use liquefied petroleum gas as a propellant, gas lighter refill bottles, tabletop gas stove cylinders, etc. However, conventional press machines have
There was a problem with the safety of the press operation because there was no device to exhaust the gas leaking from such dangerous empty cans.

The present invention focused on the problems of the conventional empty can collection work, and was made to solve these problems.The present invention was made in order to solve the problem of the conventional empty can collection work. The objective is to improve the efficiency of truck transport by collecting gas while it is being pressed, and to improve the safety of pressing operations by equipping the press with a mechanism to emit dangerous gases, thereby solving the above-mentioned problems.

(Effects of the Invention) As described above, the empty can recovery truck of the present invention has a small empty can press machine mounted on the truck bed, and unprocessed empty cans and block-shaped cans are stored in the empty space of the truck bed.・At the same time, the hydraulic pump that serves as the pressure source for the press machine is driven by the engine of the truck, so that the press machine can press the empty cans at any time and at any location. Compared to conventional empty can collection work, the efficiency of transporting empty cans by truck is greatly improved, and metal waste collectors are able to reduce the cost of empty can collection by making it easier to collect empty cans and reducing costs. This will encourage people to collect them and will make a major contribution to preventing environmental damage caused by empty cans.

In addition, in the empty can collection truck of the present invention, a through hole for degassing is provided in the pressurizing plate of the press machine to enable the movement of gas flowing into the press space inside the press machine, and also to allow the gas to flow into the press space. Because the system is designed to forcibly exhaust the filled gas through an exhaust duct with an exhaust fan, even if a can filled with dangerous gas is mixed into an empty can of canned juice, etc., the gas concentration will rapidly drop and an explosion will occur. It has the excellent effect of increasing the safety of press work by preventing the danger of accidents.
