SOLUTION: This system for collecting wastepaper by visiting is constituted as follows: an exclusive vehicle for recovery and equipped with a dry mill for fibrillating wastepaper is sent to the inside or its vicinity of the site of an office where wastepaper including confidential documents arises; the security control staff in charge of the above office throws the wastepaper including confidential documents into the dry mill for fibrillating wastepaper in the exclusive vehicle for recovery during its parking or stop in order to fibrillate the wastepaper in such a way that the contents of the wastepaper become unreadable; and the exclusive vehicle for recovery is loaded with the fibrillated wastepaper and sends it to a processor of regenerated paper products.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a used paper recycling system, and more particularly to a used paper business trip collection system.

[0002]

2. Description of the Related Art In addition to the conventional collection and recycling of newspapers and milk cartons by local communities and organizations, in recent years, as part of environmental issues, collection of used paper such as documents that have become unnecessary at offices, etc.
Recycling of recycled waste paper is desired. Normally, waste paper from offices is first cut with a shredder to maintain confidentiality, but this makes the paper fibers too short to be easily processed into recycled paper. on the other hand,
For example, there is a method in which waste paper is decomposed in a dry or wet defibration mill so as not to damage the fibers of the paper to obtain defibrated pulp so that it can be recycled.

[0003]

However, it takes a certain amount of cost and space to install the above-mentioned mill for defibration at each business establishment. Since confidential information may be leaked while the used paper is passed to the processor or carrier, in many cases, the used paper must be cut and incinerated without being recycled. The present invention has been made in view of the above problems, and the confidentiality management staff of a business establishment where waste paper including confidential documents has been generated has released the confidentiality, and the business establishment can recycle waste paper with confidence, thereby improving the efficiency of waste paper recycling. The task is to improve it.

[0004]

That is, according to the present invention, a recovery-only vehicle equipped with a dry mill for waste paper defibration is traveled to or near the premises of a business where waste paper including confidential documents is generated, and A confidentiality management officer throws the waste paper containing the confidential document into the waste paper disintegration dry mill in the recovery dedicated vehicle parked and stopped, and disentangles the text of the waste paper unreadable.
The collection-only vehicle is a collection recovery system for waste paper on-site, in which the defibrated waste paper is placed and sent to a processor of recycled paper products.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below, but the present invention is not limited thereto. Used paper, including confidential documents that are no longer needed at the business site, are temporarily stored at the business site under the control of a confidentiality manager, if necessary, until the recovery vehicle is traveled. Confidential documents are slips, receipts,
Minutes are exemplified. Ordinary papers, newspapers, flyers, and the like without confidentiality may be mixed with the confidential documents. Paper quality is high quality paper widely used for documents,
Kent paper, imitation paper, medium paper, and the like may be included. wire,
There is no particular need to completely remove foreign matter such as carbon paper.

[0006] Examples of the dry mill for defibration include a fiber riser manufactured by West Japan Technology Development Co., Ltd., which is composed of a dry defibrillator and a granulator, and MS manufactured by Meiko Shokai Co., Ltd.
S-200P (with compression device and packing device), MSC-500P made by the company
(With a compression device) and YS type or TS type shredder manufactured by Yamamoto Momoma Seisakusho Co., Ltd. The power source of the mill is not particularly limited, and examples thereof include a power source obtained from a battery of an engine of a dedicated recovery vehicle and a power source provided by a business establishment.

[0007] The recovery-only vehicle loaded with the above-mentioned mill is parked or stopped on or near the site of the business establishment. The security officer takes the waste paper including the confidential documents into the collection vehicle and puts it into the mill. Used paper containing confidential documents (hereinafter referred to as used paper) that has become illegible after being crushed by the mill is stored in a bag provided inside the vehicle from the outlet of the mill. The form of the bag is, for example, a cylinder type or a container type which corresponds to the discharge port of the mill and has a large storage capacity.

Specific examples of the dry defibration method include cutting, vibrating and loosening, and grinding. The used paper is preferably decomposed into fragments of about 3 mm square to 1 cm square or loose cotton so as to be unreadable and not to hinder the processing of recycled paper products.

[0009] The collection vehicle or the processing company travels the collection-only vehicle periodically or at the request of the business establishment. The main body of the vehicle dedicated to collection only needs to be of such a size that a dry mill for defibration and defibrated waste paper can be placed. Normally, a four-ton truck is sufficient, and if the four-ton truck cannot be loaded in a single business trip, for example, another dedicated paper loading vehicle may be prepared. Large and small vehicles may be used as appropriate depending on the processing capacity of the mill and the amount of waste paper.

In addition to the defibrating function, the dry mill for defibration includes a dust collector as a measure against dust when defibrating waste paper, a soundproof box as a measure against noise, and a compression device for reducing the volume after defibration. Function is added as appropriate. In particular, when defibration is performed by a dry method, the bulk increases. Therefore, it is preferable that a compression function is provided to increase the loading efficiency. As a countermeasure against static electricity due to dust, a trace amount of a surfactant solution may be sprayed on waste paper being defibrated.

After the defibration, the used paper packed in the bag is sent to the processor while it is placed in the vehicle for exclusive use for collection or in another vehicle for exclusive use for loading. A company that processes recycled paper products processes office supplies such as copy paper, notebooks and report paper, and sanitary supplies such as toilet paper, disposable diapers, and tissue paper from the dry-decomposed waste paper. Or
Paper products that do not require bleach, such as waste oil adsorbent (can be incinerated as an auxiliary fuel after use), water absorbent (such as pulp for disposable diapers), and filter media (removal of cutting chips from cutting oil used in machine shops) Others process solids at sewage treatment plants, etc.) and seedling pods (mixed with livestock dung, molded and returned to soil after use).

When processing the defibrated waste paper into a recycled paper product, the remaining resin and metal are removed as necessary. Resins and metals can be easily separated from paper because their specific gravities are significantly different from paper. Normally, in a paper product processing step, since wet stirring is performed once, separation is performed in water due to a difference in specific gravity. Or it is scattered by wind power and separated by specific gravity difference. Further, a resin having a strength higher than that of paper may be sieved with a crushed area. Here, release paper or the like whose surface is lipophilic-treated with silicone or the like is particularly suitable as a raw material of the waste oil adsorbent, and therefore does not necessarily need to be removed depending on the product. In addition, depending on the purpose of each recycled paper product, additives (such as antibacterial agents) that do not become toxic even when incinerated may be added in the processing step.

The above-mentioned processed product may be sold through a general recycled paper product route.
This is preferable because it allows efficient waste paper recycling. In particular, recycled paper products, such as copy paper, which are required in large quantities at general offices, are suitable.

In the above description, an office is described as a site where waste paper is generated. However, this may include various facilities such as a station, a park, and an event hall. If it is difficult to disassemble the vehicle at each site due to the parking space of the vehicle dedicated to collection, the parking may be performed at a nearby parking lot. This makes it possible to widely collect used paper from various sites.

[0015]

According to the present invention, the confidentiality of the used paper can be safely released, and the used paper can be efficiently collected and recycled.
