Description

A PAPER PRODUCTION MACHINE

TECHNICAL FIELD

The present invention relates to paper production machines which provide production of wet paper page from cellulose mixture and which provide drying of said wet paper page and which provide obtaining of paper page.

PRIOR ART

Paper is a versatile material which has very big number of usage areas. Even though paper is frequently used for printing, paper is also used for cleaning and packaging in the processes realized in industrial and construction sector.

Humid tree woods, the stems of cereals like wheat, barley, rye and rice and fiber substances obtained from cotton, etc. are used as the raw material of paper. The mixture obtained by means of fibers obtained from plants is passed through various processes and purified. This obtained cellulose mixture is named as paper pulp. Two methods are used in paper pulp production, namely, mechanical and chemical methods. The difference between the mechanical method and the chemical method is that the particles, obtained from herbal fibers, are obtained by means of washing with water or other chemical substances. Mechanical method is used for papers (newspaper, etc.) produced with low quality, and chemical method is used for producing papers with higher quality. The paper pulp obtained by means of chemical or mechanical method is passed through various steps. Another method is the production method by using waste paper. In this method, waste paper is used as the raw material, and the waste papers are recycled and they are turned into paper pulp form again.

First of all, a mixture is obtained by providing mixing of paper pulp and water with specific proportions. By means of partial separation of water from the obtained mixture, a wet paper comprising paper pulp and water is obtained. The obtained wet paper is dried and 90-95% of the water is purified on the average. Thus, a flat and smooth paper is obtained.

In order to realize said steps, there are different mechanisms provided to machines which exist in laboratory mediums. Said mechanisms comprise heavy covers for realization of the processes. The covers provided in the used mechanisms are opened by an operator and they are closed when the process is finished. Since the covers are heavy, time loss occurs and fatigue sense occurs for the operator since the operator lifts and closes the heavy covers within the day. Work loss occurs depending on time loss and fatigue sense. Since the work loss increases, the production decreases. Moreover, since the machines are not controlled automatically, the cover is repetitively opened during the drying process of the wet paper, and it is checked whether the wet paper is substantially dried or not. This condition leads to work and time loss.

As a result, because of the abovementioned problems, an improvement is required in the related technical field.

As known, paper is obtained by means of obtaining a homogenous mixture by mixing a liquid and a cellulose mixture comprising cellulose and by passing the obtained homogeneous mixture through various steps. The present invention relates to a paper production machine (10) designed to realize paper production by means of an innovative architecture.

Said cellulose mixture is passed through various steps in said paper production machine (10) and afterwards, production of the paper page is provided. First of all, mixing of said cellulose mixture with said liquid is realized in the sheet production mechanism (100) provided in the page production machine (10). In said sheet production mechanism (100), a homogenous mixture is obtained as a result of mixing the cellulose mixture with liquid and the obtained mixture is filtered and a wet paper page is produced. The produced wet paper page is passed to a drying mechanism (200) provided to the paper production machine (10) by means of a user. Said drying mechanism (200) is configured to provide drying of the wet paper page.

With reference to Figure 1 , at least one of the sheet production mechanism (100) and the drying mechanism (200) is controlled by means of a control unit (300) provided to the subject matter paper production machine (10). There is at least one memory unit (400) which keeps the predetermined duration which is needed for realization of the locking process embodied to be associated with said control unit (300). The control unit (300) is configured to be connected to a user interface (500) provided for realizing command input by means of a user. There is at least one drive item (600) provided to at least one of the sheet production mechanism (100) and the drying mechanism (200) in order to be controlled by the control unit (300). With reference to Figure 2, said sheet production mechanism (100) comprises a mixture chamber (120) wherein the cellulose mixture is kept in a manner providing mixing of the cellulose mixture with the predetermined amount of liquid. The sheet production mechanism (100) comprises a sheet formation body (110) positioned in at least one opening (121 ) on the base of the mixture chamber (120) for providing obtaining of the wet paper page by filtering the homogenous mixture obtained in said mixture chamber (120). Said opening (121) provided on the base of the mixture chamber (120) is closed by the sheet formation body (110) and the access of the user to the formed wet paper page is provided by means of diverging the opening (121), provided on the base, from the sheet formation body (110).

Said sheet production mechanism (100) comprises a first movement item (130) in a manner providing movement freedom at a first axis (700) between the position where the mixture chamber (120) is closed onto the sheet formation mechanism and the position where it is removed from the sheet formation mechanism. In other words, the first movement item (130) provides closing and opening of the mixture chamber (120) onto the sheet formation body (110) like a cover. In an exemplary embodiment of the present invention, said first movement item (130) can be a structure like at least one hinge which will provide movement freedom.

There is at least one first drive item (610) for providing realization of the abovementioned movement by the mixture chamber (120) in a first axis (700). There is a first force protrusion (140) where said first drive item (610) and said first movement item (130) are connected. Said first force protrusion (140) provides transfer of the force, produced by means of the first drive item (610), to the movement item. In other words, a leverage-like structure is obtained where the mixture chamber (120) is the load arm, the force protrusion (140) is the force arm and the movement item (130) is the support point.

Said drying mechanism (200) comprises a drying body (210) for the placement of the wet paper page produced in the sheet production mechanism (100) by means of a user. On said drying body (210), there is a first plate (211) embodied to provide the wet paper to stay in a flat form.

The drying mechanism (200) comprises at least one cover (220) for being covered in a manner staying between it and the drying body (210) of the wet paper page. There is a second plate (221) which is needed for drying of wet paper placed on said cover (220). A second movement item (230) provides the cover (220) to have movement freedom between the position where the cover (220) is closed onto the drying body (210) and the position where the cover (220) is diverged from the drying body (210). In an exemplary embodiment of the present invention, said second movement item (230) can be a structure like at least one hinge, etc. which will provide movement freedom. There is at least one drive item (600) for providing realization of the abovementioned movement in a second axis (800) by the cover (220). There is a second force protrusion (240) where said second drive item (620) and said second movement item (230) are connected. The second force protrusion (240) is embodied to arrange the movement of the second drive item (620).

An exemplary operation scenario of the present invention is described below;

The cellulose mixture is placed onto the sheet formation body (110) by means a user. The mixture chamber (120) is covered depending on the placement of the cellulose mixture. A homogeneous mixture is obtained as a result of mixing cellulose mixture and predetermined amount of water provided from the sheet formation mechanism (100). The obtained homogenous mixture is filtered, and water is partially separated. Thus, wet paper page is formed on the sheet formation body (110). After the filtration process in the mixture chamber (120) is completed, a command is sent to the control unit (300) in a manner providing opening of the mixture chamber (120) with the user interface (500) by means of a user. The control unit (300) generates a signal which will trigger the first drive item (610) depending on the open command for the mixture chamber (120). The first drive item (610) moves in a first direction depending on the coming signal. Movement of the first drive item (610) in said first direction is transferred to the first movement item (130) by means of the first force protrusion (140). Thus, the mixture chamber (120) is opened depending on the movement of the first drive item (610) with the help of the first movement item (130). The wet paper page is taken from the sheet formation body (110) by a user, and is placed onto the first plate (211) provided on the drying body (210). The mixture chamber (120) is closed by the user manually for safety. The closed mixture chamber (120) is locked during the predetermined duration kept in the memory unit (400). The mixture chamber (120) is opened only depending on a command received from the user interface (500) and otherwise the mixture chamber (120) stays locked.

The cover (220) is manually closed onto the wet paper page, placed onto the second plate (221), by the user. Thanks to the structures placed on the first plate (211) depending on the closed cover (220), the wet paper is dried for a predetermined duration. In case the predetermined duration is completed, the control unit (300) generates a signal which provides triggering of the second drive item (620) so as to move in a second direction. The movement of the second drive item (620) in said second direction is transferred to the second movement item (230) by means of the second force protrusion (240). Depending on the movement of the second drive item (620), the cover (220) is opened with the help of the second movement item (230). The wet paper page is controlled by the user. In case the wet paper page is substantially dried, it is taken from the drying body (210). In case the wet paper page is not substantially dried, the cover (220) is manually covered by the user and the drying process continues for duration which is predetermined by means of the user interface (500).

In an exemplary embodiment of the present invention, the cellulose mixture is placed onto the sheet formation body (110) by means of the operator. Depending on the placement of the mixture, the mixture chamber (120) is closed by the operator. The closed mixture chamber (120) is locked for duration of two seconds kept in the memory unit (400). At the end of two seconds, the sheet production mechanism (100) begins to operate. Predetermined amount of water is sprayed to the cellulose mixture and a new mixture having homogeneous structure is obtained. Water is removed from the mixture obtained by means of vacuum provided to the sheet production mechanism (100). Wet paper page is obtained by means of removing water partially from the mixture. When the process is completed, the first piston is triggered by means of the control unit (300) and moves downwardly. Hinge is used for providing opening movement of the mixture chamber (120). Depending on the movement of the piston, the hinge moves and the mixture chamber (120) is opened. The operator places the wet paper page with the help of the filter onto the second plate (221) provided to the drying mechanism (200). After the placement process, the cover (220) is closed by means of the operator. In case the cover (220) is closed, locking process is realized during two seconds kept in the memory unit (400). At the end of two seconds, the drying process is begun and the process duration is determined as ten minutes by the operator. At the end of ten minutes, the second piston is triggered by means of the control unit (300) and the piston moves downwardly. Hinge is used for providing opening movement of the cover (220). Depending on the movement of the piston, the hinge moves, and the cover (220) is opened. In case the wet paper page is substantially dried, the page is taken from the second plate (221). In case the wet paper page is partially dried, the cover (220) is closed again and the drying process continues during the duration determined by the operator. Afterwards, the cover (220) is automatically opened and paper production is realized.

The protection scope of the present invention is set forth in the annexed claims and cannot be restricted to the illustrative disclosures given above, under the detailed description. It is because a person skilled in the relevant art can obviously produce similar embodiments under the light of the foregoing disclosures, without departing from the main principles of the present invention.
