  According to the crushing and separating apparatus for packaged food disclosed in each of the above-mentioned conventional technologies, the packaged food is crushed and pulverized within a short time, and the garbage to be subjected to incineration and the synthetic resin to be reused are made. In terms of separating and collecting container materials, excellent results have been confirmed. However, in the sorter proposed in Patent Document 1, garbage that is a pulverized product adheres to and accumulates on the inner wall surface of the cylindrical sorter main body, which not only lowers the sorting efficiency but also the packaged food. There is a concern that a part of the packaged food or the pulverized packed food supplied in the input hopper flows backward. Further, in the packaged food sorting apparatus disclosed in Patent Document 2, the crushing blades attached to the horizontal axis of the rotor are provided with two pieces that are opposed to each other with an interval of 180 ° around the horizontal axis. Three types of crushing: one crushing blade, two second crushing blades provided in opposition to each other at an interval of 90 °, and a short additional crushing blade provided opposite to each other only on the upstream side of the horizontal axis By providing a blade and further bending the upstream portion of each crushing blade, and using it as a blower fan that generates a flow of air from the upstream side to the downstream side, etc. Although the sorting and collection of packaged foods have been improved so that they flow smoothly, there remains a problem that the entire apparatus is structurally complicated and expensive. On the other hand, in the crushing and separating apparatus according to Patent Document 3, the packaged food is crushed and crushed in a short time by providing an angled metal member at the tip of the rotor or a band-shaped scraper made of an elastic member. Although it is considered that garbage etc. does not adhere to the inner wall surface of the drum casing, etc., if the packaged food is udon or cooked rice, so-called kneading occurs and deposits, so depending on such physical means, It was a major problem that could not prevent deposition and deposition, and that was desired to be solved immediately.

  As a result of intensive studies aimed at solving the above-mentioned problems, the present inventors have focused on the release agent properties inherently possessed by water, and utilize the release agent properties possessed by water. As a result, a crushing and sorting apparatus for packaged foods and the like having excellent crushing and sorting performance despite a simple structure was completed.

  That is, the crushing and sorting apparatus for packaged food according to the present invention crushes the input food in a packaging container by the rotation of the rotor in the crushing and separating apparatus body comprising a cylindrical drum casing, and the foods and containers In a crushing and separating apparatus for packaged food that is separated and collected, a water hole is formed in the axial center of the rotating shaft of the rotor, and water is injected into the drum casing through a water ejection hole provided in the water hole. The gist of the packaged food crushing and separating apparatus is characterized by crushing and collecting the food contained in the packaged container.

 Further, in the crushing and sorting apparatus for packaged food according to the present invention, the water holes are respectively extended and drilled inside the shaft center through rotary joints provided on the outer sides of the left and right bearings of the rotor rotation shaft, The water injected from the water inlet provided in the rotary joint is ejected from the ejection hole of the water hole.

 Furthermore, according to the crushing and separating apparatus for packaged food according to the present invention, the amount of water ejected from the water hole during the crushing and separation is controlled to 1/10 to 1/5 with respect to the maximum ejection amount. It is a feature.

 The crushing and sorting apparatus for packaged food according to the present invention is also configured such that foods crushed and separated in the drum casing are discharged into a garbage storage container through a rooster provided below the drum casing and crushed and separated. The packaging containers are characterized in that they are discharged through a discharge duct provided above the drum casing and collected in a packaging material storage container.

  According to the crushing and separating apparatus for packaged food according to the present invention, a water hole having a plurality of ejection holes is drilled in the rotation shaft of the rotor in the crushing and separating apparatus body comprising the cylindrical drum casing of the apparatus body, and the water The basic constituent requirement is to crush and separate the packaged food to be introduced while injecting water into the crushing / separating device body through the hall. It is sprayed in the sorter main body and adheres to the rotor, the crushing blade at the tip of the rotor, the crushed packaged food itself and the surface of the packaging material as well as the inner wall of the main body to form a coating film. The coating film formed by this water acts as a so-called release agent, effectively preventing the crushed garbage from adhering to any part in the separation device and preventing them from accumulating in the device. Therefore, the crushing and sorting operation of the packaged food according to the present invention proceeds quickly and efficiently. The crushing / separating apparatus according to the present invention can be transferred directly from the structure of a conventionally known rotor and crushing blade, and does not need to be processed into a complicated structure or shape. Therefore, the crushing / separating apparatus itself is extremely simple and compact. In addition, the water hole according to the present invention is configured so that a large amount of water is ejected when cleaning the inside of the apparatus, enabling powerful cleaning by water washing, and is spent for maintenance of the apparatus. Excellent results have been confirmed, such as extremely shortening the downtime of the crushing and separating apparatus.

As shown in FIG. 2, the rotors 3, 3a, 3b in the present embodiment have one longest first rotor 3 with a crushing metal plate 3-1 attached to the tip, and the crushing metal plate 3a. -1 is attached with two medium-sized second rotors 3a, and the shortest third rotor 3b with the same crushing metal plate 3b-1 is attached with one piece. The rotor pipe 4-6 covering the outer periphery is firmly fixed by bolting or the like.
Below the crushing and separating apparatus main body 2 according to the present embodiment, there is provided a rooster 7 from which crushed and crushed foods are discharged, and a movable storage box for storing garbage (not shown) below the rooster 7. On the other hand, a discharge duct 8 that discharges and collects the crushed packaging material is provided above the crushing and separating apparatus main body 2, and the discharged packaging material is disposed at the tip of the discharge duct 8. A movable storage box (not shown) for collection is provided. In addition, a hopper 6 provided with a loading port 6-1 for loading packed food to be sorted is provided on the upstream side surface portion of the crushing and sorting apparatus main body 2.

  In the present embodiment, the rotary shaft 4 that is built through the shaft center portion of the crushing / separating apparatus main body 2 is supported by bearings 4-3 and 4-4 provided on both side surfaces of the main body, and one of the bearings 4 is supported. A pulley 4-5 is attached to the outside of -3, and the rotation of the motor M is transmitted via a belt. Here, a water hole 5 is bored through the further axial center portion of the rotating shaft 4 in the present embodiment, and the crushing / separating apparatus main body is provided through a plurality of jets 5-1 provided in the water hole 5. It is comprised so that water may be inject | poured into 2 inside. In this embodiment, the water hole 5 is connected to one water inlet W1 via a rotary joint 4-1 provided on the outer side of a pulley 4-5 attached to the outer side of the bearing 4-3.

Are drilled without intersecting each other while penetrating almost to the center of the rotating shaft 4.

  When crushing and sorting packed food in the crushing and sorting apparatus for packaged food based on the present embodiment having the above-described configuration, the rotor 3, 3a, and 3b are started as the motor M rotates. As for the rotational speed of 3a, 3b, it is desirable to ensure about 600 rpm normally. When the rotation of the rotors 3, 3a, 3b reaches the rated value, the valve of one water inlet W1 corresponding to the upstream side is opened and water injection into the water hole 5 is started. It is limited to about 1/5 at the time of injection. The injected water is introduced into the crushing / separating apparatus main body 2 from the jet nozzle 5-1 provided in the water hole 5, and the crushing metal plates 3-1, 3a-1, as the rotors 3, 3a, 3b rotate. It is diffused in the form of a spray by the wind pressure of 3b-1, penetrates to every corner in the main body 2 and wets its surface to form a coating. Next, the inlet 6-1 of the hopper 6 in which the packaged food subjected to disposal is stored is opened, the packaged food is loaded, and the crushing and sorting operation is started. The packaged food charged in the apparatus main body 2 is immediately crushed and pulverized, and the foods are stored in the garbage container through the rooster 7 provided below the apparatus main body 2 by its own weight, and sequentially incinerated. After being subjected to disposal, the pulverized product such as a lightweight plastic container is classified by the wind pressure accompanying the rotation of the rotors 3, 3 a, 3 b, and passes through the discharge duct 8 provided on the upper downstream side of the apparatus body 2. Then, it is discharged out of the system, stored in a movable collection box connected to the discharge duct 8, and stored as a recycled resource.

 According to the crushing and separating operation of the packaged food according to the present embodiment, not only the inner wall surface of the crushing and separating apparatus 2, but also all the rotors 3, 3a, 3b including the rotor pipe 4-6 and the crushing metal plates 3-1, 3a. 1, 3b-1, etc. showed almost no adhesion and accumulation of garbage formed by pulverizing foods, and it was confirmed that the crushing and fractionating operation was continued in a healthy state. In addition, after a certain amount of crushing and separation work, the input of the packaged food is stopped, and the valve of the upstream water inlet W1 is fully opened to clean the inside of the apparatus body 2, and the valve of the downstream water inlet W2 is also fully opened. As a result, water was injected in a full state, and when the rotors 3, 3a, 3b were fully rotated, it was also confirmed that the inside of the apparatus was cleaned and cleaning was completed in a very short time.

  As is clear from the above embodiment, according to the crushing and sorting apparatus for packaged food according to the present invention, a water hole that penetrates to the inside of the apparatus main body is formed in the axial center of the rotating shaft of the rotor, and the water hole passes through the water hole. Then, a coating film made of water is formed on all the members provided inside the apparatus main body, including the inner wall surface of the apparatus main body, and the coating film acts substantially as a release agent. Prevents crushed garbage from adhering to various members and prevents them from accumulating. In addition, the amount of water used in the crushing and pulverizing operation is very small, so that the labor and cost required for collecting and removing the injected water are almost negligible. Therefore, the crushing and sorting apparatus for packaged food according to the present invention can continue a quick and efficient crushing and sorting operation for a long time. Furthermore, when the water hole according to the present invention is cleaned in the apparatus main body, the efficiency of the cleaning can be easily improved by injecting water that is fully jetted into a rotor that rotates at a high speed in the main body. The time required for maintenance is also drastically shortened, and significant cost savings are possible.
