[Industrial applications]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shredder for confidential processing paper and the like, and particularly to an engine driven configuration for processing a relatively large amount of paper for business use or the like.
[0002]
[Prior art]
2. Description of the Related Art Many shredding machines for confidential processing paper, waste books, cardboard wrapping paper, and the like are conventionally provided with a cutter device at an upper portion and a bag for storing small fragments at a lower portion for general office use.
On the other hand, financial institutions and public organizations have introduced system equipment for large-sized shredders.
[0003]
[Problems to be solved by the invention]
In business enterprises where a certain amount of confidential documents are generated on business, shredders may be installed using offices and warehouses, but it is not necessary from the raw material input port to the discharge storage section In addition, it requires a horizontal space or a vertical space, which is inefficient in using the area space.
Further, in the case of a delivery service system in which a shredding device is mounted on a truck or the like by a processing company to move, it is necessary to efficiently utilize the space of the truck bed, and a unit-type independent drive type equipped with an engine or the like can be considered. However, there has been a problem that, after a certain period of operation, the surroundings of the engine become a high-temperature heat reservoir, resulting in a so-called overheating phenomenon, making it difficult to continue the operation.
[0004]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, a machine frame, a cutter device provided with an insertion port on one side of the machine frame, a conveyor carrier for conveying a small fragment cut by the cutter device, A collection unit that is moved by the conveyor carrier and installed at one end of the moving end to collect small fragments, and an engine is installed inside the machine frame, and the cutter device and the conveyor conveyor are driven by this engine. In a shredder such as confidential processing paper covered with a cover body, an intake port for outside air is provided at the front of the engine cooling fan, and the engine is cooled at the rear of the engine to discharge hot air that has absorbed the high heat of the engine. The present invention provides a shredding machine for confidential processing paper or the like, which is provided with a means for performing such processing.
Another object of the present invention is to provide a shredder for confidential processing paper or the like in which a forced ventilation fan is provided as a means for discharging hot air.
[0005]
[Action]
The shredder having the above-described configuration can be efficiently installed near a wall in a corner of an office. Alternatively, since it can be easily mounted on one side of the truck bed, an operator who inputs processing paper or the like can continuously store and manage small fragments in the same place while inputting.
In addition, since the engine is used as the power source, it can be installed at a desired location regardless of the presence or absence of a power source, and the entire appearance is set to be compact. In addition, the cooling fan of the engine cools the engine, absorbs the outside air, and performs a circulation function of exhausting the air. The machine frame is provided with a means for discharging hot air by a separate ventilation fan, so the circulation with the outside air is more reliable. And no overheating.
