Machine separating parts of plastic containers for recycling. Object of the invention

The present invention, as expressed in the statement of this specification, refers to a machine for separating parts of recyclable plastic containers intended to automatically separate caps, labels and other elements of the package, so as not to separating the parts of the package assembly that are made of different materials, then a contamination of the product that was manufactured later would result in recycling.

They are containers from urban solid waste, mainly PET plastic containers, polyethylene, bottles, tubes, bottles, etc.

Thus, the object of the invention is a machine that separates the caps, labels and other elements on one side and the container itself on the other.

Therefore, the machine of the invention performs the separation of the cap and the label and other possible small elements, in addition to the dirt that adheres to the container, leaving the same clean and whole for later treatment, so that this operation is It is carried out by dry route, although it could undoubtedly also be carried out by wet way.

The measures of the machine as well as the different elements and the power of the motor that mobilizes the different mechanisms, are variable depending on the needs and the quantity of product to be treated. Background of the invention

At present, plastic containers are recycled as a whole, that is to say that both the container itself and the caps, labels and other possible elements, such as independent handles, crush this whole set cited, and then re-manufacture new containers and / or caps, handles, etc.

The mixing of the different materials of the elements that make up the package is not adequate, since contamination problems can occur in the new product obtained. Description of the invention

In order to achieve the objectives and avoid the inconveniences mentioned in the previous sections, the invention proposes a machine for separating parts of plastic containers for recycling that is characterized in that it comprises a rotating rotor composed of an axis and a series of radial elements, the rotor assembly being located inside a tank that incorporates at least one lower grill with a multitude of through holes as a perforated bottom of the tank, so that the containers are introduced into said tank to be dragged, moved and beaten continuously by the radial elements during the rotation of the rotor, whereby the different component elements of the package assembly will eventually separate so that, after time, only the containers themselves will remain inside the tank while the rest of the smaller elements (plugs, labels, etc.), and even traces of organic materials, waste s food, etc., all of them will go outside by gravity through the holes of the perforated bottom of the tank reaching a mechanicrecycled, in this way, the containers themselves that remain inside the tank will be extracted completely clean for later recycling as well. .

Rotation of the rotor and endless mechanism is carried out by means of a motor element and the corresponding transmissions.

In turn, the machine comprises a robust housing formed by a lower part and an upper part constituting a cover for access to the interior of said housing where the tank is located.

Said lid is opened and closed by a powerful hydraulic cylinder, for example.

On the other hand, the machine incorporates an entrance mouth to introduce the complete containers and an exit mouth where the containers themselves leave without their small additional elements (caps, labels, etc.).

Another feature of the invention is that the radial elements that successively hit the packages comprise a structure determined for example by chains, cables, belts, etc., elements in general that are not rigid, although this possibility could also fit.

Next, in order to facilitate a better understanding of this descriptive report and as an integral part thereof, some figures are attached in which the object of the invention has been shown as an illustration and not a limitation. Brief description of the drawings

j) of one of the bases of the tank 8 to allow the entry of material into it.

On the other hand, on the opposite side of the housing there is an outlet of material 10 arranged in correspondence with a side wall of the lower part 1 of the housing, said outlet 10 being faced with another lower opening (not also shown in the figures ) from the other base of the octagonal deposit

8. By said material outlet 10, the containers themselves will be removed without the caps, labels and other elements associated with such packages that during the rotation of the rotor 5 have been detached from said container itself.

Finally, below the octagonal tank 8 there is an endless mechanism 11 for collecting the small elements mentioned, such as caps, labels and other elements detached from the container itself, which will pass through a multitude of perforations 15 of the side walls of the tank 8 until the aforementioned endless mechanism 11 is reached by gravity, which will drag these small elements to the outside of the housing.

The rotary movement of the rotor 5 is carried out by means of a motor 12 and an intermediate transmission 13, motor 12 fixed at the base of the lower part 1 of the housing.

The axis 6 of the rotating rotor 5 has short appendages 14 where the radial chains 7 are connected.

Simple anchoring mechanisms 16 are also provided to ensure the closing of the cover 2 of the housing during the operation of the machine for safety.

With this arrangement described, the containers are introduced through the inlet 9 to the tank 8 to be moved and beaten continuously by means of the radial chains 7 driven by the rotation of the rotor assembly 5, whereby the different component elements of the package assembly they will end up separating, so that after time only the containers themselves will remain inside the tank, while the rest of smaller elements (caps, labels, etc.), and even remains of organic materials, food waste etc., they will go outside by gravity through the holes of the perforated bottom reaching the endless mechanism 11 that will drag these smaller materials outwards as referred to above.

Finally, it should be noted that the opening and closing cylinder 4 of the flip-up cover 2 is hingedly connected in lugs 17 and 18 integral with the cover 2 and lower part 1 of the housing.

2. Statement motivated according to articles 29.6 and 29.7 of the Regulations for the execution of Law 11/1986, of March 20, on Patents on novelty and inventive activity; quotes and explanations in support of this statement The object of the invention is a machine for separating parts of plastic containers for recycling, which separates small elements, such as caps, labels or food scraps, with respect to the container. The machine incorporates a rotating rotor provided with radial elements that mobilize and hit the containers, which are housed in a tank provided with perforations, where the detached elements leave. The rotor and said radial elements are inside the tank. Document D1 discloses a machine for separating parts of plastic containers for recycling, which separates small elements, such as labels, dirt or residual liquids, with respect to the container. The machine incorporates a rotating rotor provided with radial blades that move and hit the containers, which are housed in a reservoir provided with perforations, where liquids and loose dirt come out. The detached labels are subsequently separated from the containers by sieving or subsequent screening. The rotor and said radial elements are inside the tank, the rotor and the tank being supported in an outer housing. The housing has, in two sides, an inlet and an outlet, both communicated with the interior of the tank through its openings. The rotor has on its axis elements for screwing radial blades. The deposit is shaped like a prismatic structure, and the direction of the rotor in it coincides with the opposite centers of the polygonal bases of such a prismatic structure (see paragraphs 9-13; 55-71; figures). Therefore, claims 1,9,10 are novel in relation to what is disclosed in document D1 (Art. 6 LP). With respect to dependent claims 2,3,5 and 6, that the housing has an upper hinged lid hinged to the lower one, is considered an obvious option for the person skilled in the art, which does not imply inventive activity. Also, in relation to dependent claims 4,7 and 8, the use of a lower endless mechanism to move the collected material, or the use of chains or braces as radial elements, are all common knowledge in the state of the technique, which does not imply an inventive activity.
