Description

One Sandpaper Packing Machine And Double Wrap Packing Method

TECHNICAL AREA

Invention, abrasive packaging machine and relates to the method in which said machine is used.

PRIOR ART

Abrasives, to obtain a smooth surface by removing surface roughness and It is a material used to clean rust, old paint and varnish. It consists of abrasive crystallized sand grains. It is generally used in many areas in the construction and manufacturing sector. Sanding is the smoothing of surfaces made of materials such as metal, wood, marble, plaster. It is the last treatment before painting and priming. In addition, abrasives are used in the removal of old paint and varnish on wooden surfaces. It is also used to clean rust and dirt on metal surfaces. In constructions, sanding is applied to smooth the walls made of satin plaster before painting. Sanding is done by hand as well as with sanding blocks or sanding machines.

It is classified according to the size of the crystallized sands on the sandpaper surface;

• Very Coarse Abrasives: 24-36 grit sanders is quite high abrasive properties because they have very coarse grains of sand.

• Thick Coarse: 40-60 grit abrasives have coarse grit and It has high abrasive properties.

• Medium Abrasives: 60-100 grit abrasives have medium grit grains and it has moderately abrasive properties.

• Fine Abrasives: Abrasives between 120-220 grit are sold in the market as fine sandpaper.

• Very Fine Abrasives: Abrasives between 240-400 grit are considered very fine.

The term “Grit”, which is most used in our country, is specified as grit in the Coated Abrasive Manufacturers Institute (CAMI) standard, which is an American Standard. The grit value indicates the amount of grain per unit area on the sanding surface. The more grains of sand per unit area, the finer the sandpaper will be. So the sand value will be high. The smaller the grain of sand per unit area, since the grain sizes will be larger, the sandpaper will be coarser. The sand value is lower.

During transportation or storage of materials such as sandpaper with abrasive surface problems such as the abrasive surface damaging the material used in packaging are encountered. The packaging material is selected according to the type of sandpaper. However, due to its abrasive feature, the friction of the abrasive against the package causes a decrease in the usage time and deformations in the package. To avoid this problem, materials with abrasive surfaces should be wrapped as tightly as possible. And packaging materials that cause minimal problems during transportation should be selected.

The packaging of materials with abrasive surfaces is carried out with the help of packaging machines. Theese machines wound with a single winding method. In the single winding model, there are 3 shafts. These shafts look like iron pipes. One of the shafts does not move at all, and its position always remains constant. (It does not rotate around itself or around an axis.) Although the shaft does not rotate, it moves forward or backward as a whole. This integrity; fixed single shaft consists of the engine of that shaft and the weight system that creates the tension force. The other two shafts are positioned opposite each other around an axis. These two shafts and the motor to which the shafts are connected are completely fixed, does not move. While these shafts do not rotate around their own centers, they draw a kind of circle by rotating together on this axis on which they are positioned. This circular motion is provided by the rotational motion created by the motor.

In the working principle, first of all, the single non-rotating shaft and the two shafts rotating around an axis are brought closer to each other. The product, which has been made into a wide belt, is passed on these shafts. After the product is passed on to the shafts, a protective cardboard is wrapped on it. This protective cardboard prevents the product from being damaged by contacting itself during winding. Then, the spindle, which we call the upper pressure spindle, presses on the product and stretches the product. This pressing action creates a vertical tension and ensures that the product is stretchly wrapped. After these steps, the winding process begins. While the single shaft holds one end of the product in a way, the other two shafts rotate clockwise around an axis and wrap the product inside itself. While the winding process continues, its horizontal tension is provided by the force created by the weight attached to the single shaft. After the product winding is finished, one side is single-layered in the form of a circle, while the other side is multi-layered in the form of a circle wrapped on top of each other. After the winding is complete, the tension between the shafts must be released. The tension between the shafts is provided by the weight attached to the fixed shaft. The fixed shaft must be pulled manually by hand to bring the shafts closer together. This approximation process facilitates the packaging of the product. And facilitates the removal of the product from its location. A rectangular outer protective cardboard is placed on the wrapped product. The mouths of this cardboard box are closed and the final product is obtained.

The above method, which is defined as the single winding method, is used conventionally and many problems arise.

The strength of the product packaged with a single winding against physical intervention and impacts is insufficient. When the product is exposed to any physical intervention, it makes an undesirable stretching movement. This stretching movement creates breakage or rupture from the joints, which are the joints of the product, and deforms the product. This deformation can return as cost and customer complaints.

In the single winding method, the product packaging width is high and it creates a disadvantage in terms of transportation costs, (width of circles, diameters formed after winding) In the single winding model, if the packaging diameter is reduced to the desired diameter, the product is damaged because it is wrapped too tightly and has low strength^ Package measurement values wrapped in single winding model; Its transverse dimension is 365mmx285mm, and the length range is 1600mm - 3500mm.)

The fact that one end of the winding shaft is free and not connected anywhere causes circles or ovals of different widths to form on both sides of the packaged product. For this reason, winding symmetry cannot be maintained in the packaging process.

In the single winding packaging model, extra labor is needed to stretch the product to be wrapped and to fix the product in order to pack it after the winding is done. There is a system that works manually for the process steps such as stretching the product or fixing the product. Manual work is provided by labor. For this reason, extra time is needed in such steps.

The following documents were encountered during the preliminary patent search.

Taiwan document with reference number TWM543498U mentions a device that provides multi-layer winding. Abrasive surfaces of it is not possible to use the said device on abrasive surfaces in winding due to the narrow winding area of the device and the inability to wind the abrasive surfaces with proper tension. In order for the device to work in the packaging area, many fundamental changes and different sequences of action are required.

In the Chinese document application number CN1056441 18A, a device that can make single-layer winding and has a design that will prevent the material from being worn is mentioned. The invention aims to reduce the friction between a movable shaft and the support fabric in contact with the abrasive surface and the abrasive surface during the winding of materials with an abrasive surface. However, if it is used in the packaging area, it does not seem possible to wrap in the desired tension and prevent damage to the abrasive surface.

As a result, all the problems mentioned above have made it necessary to make an innovation in the related field.

OBJECTIVE OF THE INVENTION

• Operator digit (13), to facilitate the operator to observe and/or intervene when necessary.

• Helping the operator maintain balance and a support (14) to prevent damage to the device and/or person/persons in the event of an accident by restricting the movement area of the person(s) on the operator’s digit (13). • Alignment beams (15) to prevent the inner packing (18) from wrapping wrinkled and/or folded while the operator is wrapping the package.

• Motor support leg (16), in order to reduce the vibration of the system due to its movement and vibration in case of operation of the movable and fixed motor (7,8).

• Balancing leg (17) to compensate for the elevation created by the engine support leg (16) and to increase the stability of the device.

The fixed double shaft assembly (1 ) and the movable double shaft assembly (2) are configured in such a way that the two winding spindles can rotate around their own axis without interfering with each other.

The packaging device (20) wraps the one-piece material with an abrasive surface to be wrapped in two solid rolls. For this reason, it is aimed to make innovations in the technical field as double winding technique.

Working principle of the invention based on the wrapping of the inner packaging (18). basically the fixed and movable axes of rotation (D1 , D2) of the fixed double shaft assembly (1 ) and the movable double shaft assembly (2) product with abrasive surface (30) with abrasive surface around the fixed shaft (101 ) and the moving shaft (201 ) with its rotation as the center. In this technique, which is named as the double winding technique based on the image given in Figure 10, the packaging device (20) is configured to perform this principle in the most appropriate tightness.

First, a bobbin (180) is placed on the fixed shafts (101 ) in the fixed dual shaft assembly (1 ) and the movable shafts (201 ) in the movable dual shaft assembly (2). In the preferred embodiment of the invention, the bobbin (180) is made of cardboard. The use of cardboard material ensures the use of recyclable materials and reduces the damage to the environment.

In an alternative embodiment of the invention, the bobbin (180) is made of recyclable plastic material.

Then, as seen in figure 6, product with abrasive surface (30) with a one-piece abrasive surface and the inner packaging (18) are placed on the bobbin (180) on the fixed and movable shafts (101 , 201 ). The inner packing (18) is used to limit contact of abrasive surfaces to extend the life of both the abrasive and spindles and increase maintenance time. In the preferred embodiment of the invention, product with abrasive surface (30) with abrasive surface, which is desired to be packaged, is placed between the bobbin (180) and the inner packaging (18). In an alternative embodiment of the invention, at least one product with abrasive surface (30) packaging is possible product with abrasive surface (30) between at least two inner packaging (18) and so that the product (30) with each abrasive surface remains between the inner packagings. That is, it is possible as an alternative embodiment to package the product with abrasive surface (30) more than one abrasive surface in the same package as the packaging device (20).

After positioning, sliding spindle head attached to the engine (5) connected to the motor closes the end of the fixed shafts (101 ) included in the fixed double shaft group (1 ). Sliding spindle head attached to piston (6) connected to the piston, on the other hand, closes the ends of the moving shafts (201 ) included in the moving dual shaft group (2). In this way, when the winding process is started, the product with abrasive surface (30), the bobbin (180) and the inner packaging (18) are prevented from slipping out.

The attachment of the inner packaging (18) to the fixed and movable double shaft groups (1 , 2) without wrinkling or folding is provided by passing it through at least one alignment beam (15). Alignment beams (15) are configured in the upper and lower parts of the support (14) to be parallel to the support (14) in the preferred embodiment of the invention. According to the front view of the device in figure 2, the inner packaging (18) enters the packaging device (20) from the right (S1 ) side.

After the product (30) with abrasive surface and the inner packaging (18) are positioned to be packaged as in figure 6, with the help of the control unit (11 ), the upper pressure piston (4) stretches the representation given in figure 7 as shown by lowering the upper pressure shaft (3), the product with abrasive surface (30) and the inner packaging (18).

This tension is provided by controlling the tension of the product and packaging material between the fixed double shaft group (1 ) and the movable double shaft group (2) by moving the Upper oppression piston (4). Upper oppression spindle (3) makes the product taut by applying compression force to the product from the top before wrapping the packaging. During the winding, it adjusts the tension and moves vertically to the ground with the help of the Upper oppression piston (4) as the amount of the product to be wrapped decreases. This vertical movement is also created by the pushing force of the product to be wrapped. Operator it is ensured that the product has the desired tension and that the desired winding method is done correctly by the operator taking the space on the product by going up to the operator digit (13).

In the preferred embodiment of the invention, the winding process is carried out by rotating the fixed double shaft assembly (1 ) and the movable double shaft assembly (2) simultaneously. When the rotation process is viewed from the point of view of the packaging device (20) in figure 2, the winding process is carried out in such a way that the movable double shaft assembly (2) and the fixed double shaft assembly (1 ) rotate clockwise or counterclockwise in the same direction. During the winding, an image is formed as in figure 7. The winding process is started by starting the fixed engine (8) and the engine piston (9) from the control unit (1 1 ).

While the fixed double shaft assembly (1 ) does not move during the winding process, the movable double shaft assembly (2) approaches the fixed double shaft assembly (1 ) due to the tension of the product with abrasive surface (30) and the inner packaging (18). The approach direction is maintained by the engine piston (9) and the shaft piston (10). The engine piston (9) and the shaft piston (10) are not connected to any drive train. The engine piston (9) not only dampens the vibrations created by the moving engine (7) to a certain extent, reducing the vibration, but also enables the moving engine (7) to move in a controlled direction. The engine piston (9), on the other hand, enables the sliding spindle head attached to piston (6) connected to the piston to move in a controlled direction and facilitates the connection with the moving shaft (201 ).

During the approach process, the control unit (1 1 ) ensures that the upper oppression piston (4) lifts the upper oppression spindle (3), preventing the fixed and moveble double shaft assembly (1 , 2), and a representation as in figure 8 is formed. In the preferred embodiment of the invention, the upper oppression piston (4) is programmed to operate automatically in case the moving double shaft assembly (2) approaches, raising the upper oppression spindle (3) and preventing unwanted pressure.

In an alternative embodiment of the invention, the winding process is carried out by first rotating the moving double shaft assembly (2) or the fixed double shaft assembly (1 ), then rotating the unturned shaft group and keeping the rotated shaft group fixed.

After the winding process is completed, the moving double shaft assembly (2) and the fixed double shaft assembly (1 ) come to the closest position to each other. As a visual representation of the resulting invention, when viewed from the front, it is as given in figure 9. The sliding spindle head attached to the engine (5) connected to the motor associated with the fixed shafts (101 ) and the sliding spindle head attached to piston (6) connected to the piston associated with the moving shafts (201 ) are separated from the point where they are associated. On the fixed double shaft assembly (1 ) and the movable double shaft group; an outer packaging (19) is passed to cover the bobbin (180), the inner packaging (18) and the product (30) with the abrasive surface remaining inside the inner packaging (18). The bobbin (180) are preferably made of recyclable cardboard, varying in length between 1900mm and 2800mm, having a wall thickness of 3mm, an inner diameter of 76mm and an outer diameter of 82mm. In Figure 10, the representative front view of the packaged product formed by passing the outer packaging is given. In the preferred embodiment of the invention, the outer packaging (19) is made of corrosion-resistant material to provide protection to the product with abrasive surface (30) from external factors in case the product with abrasive surface (30) shatters the inner packaging (18) with abrasion during storage and transportation. The outer packaging (19) mentioned in the preferred embodiment of the invention is cardboard.

After wrapping the outer packing (19) around the double-wrapped product, the product with abrasive surface (30), inner packing (18), outer packing (19), and bobbin (180); The bobbin (180) are separated from the fixed and movable dual shaft assembly (1 , 2) by rubbing against the fixed shafts (101 ) and the movable shafts (201 ). The packaged materials, which are formed by cutting the connection of the bobbins (180) with the fixed and movable shafts (101 , 201 ) through which they are passed, are separated from the packaging device (20) with the help of the operator.

In the preferred embodiment of the invention, the cover is connected to the two ends of the packaged materials separated from the packaging device (20), thus preventing anything from entering the double winding roll, (the cover mentioned is not shown in the figures) During transportation and storage, living and/or inanimate materials entering the double wrap roll are prevented from damaging the packaged product. Thanks to the cover, breakings starting from the exposed end of the product with abrasive surface (30) with abrasive surface and crushing if placed on top of each other can be prevented. The packaging device (20) is suitable for use in product with abrasive surface (30) with abrasive surface that meet certain criteria. The product with abrasive surface (30) with abrasive surface is ductile enough to be wrapped around a bobbin (180) for the winding process, and the fixed shaft (101 ) and the moving shaft (201 ) are closest to each other in order to be able to wind between the fixed shaft (101 ) and the moving shaft (201 ). must be at least twice the length of the distance.

Based on the information described above within the scope of protection, the invention is a method of packaging with double wrapping. Packing method with double wrapping; a) Placing the product in the packaging device (20), b) Performing the stretching process, c) Winding process as double roll, d) Passing the outer packaging (19) to cover the double roll, e) Separating the packaged product from the packaging device (20) it is characterized by including method steps.

The double winding method is used for the product with abrasive surface (30) with abrasive surfaces, but it can also be used in the winding process of products that want to be stretched and wrapped in rolls. A winding model with the appearance of a double roll is formed by the rotation of two parallel rotation elements in the same direction in their own axes and the material to be wound associated with the two rotation elements at the same time, which is first stretched and then rotated. In case of winding with double winding technique, the image in figure 9 is formed.

Wrapping the product to form a roll requires both more time and more energy than the double wrapping technique. Compared to the previous technique, the double wrap packaging method not only provides packaging in a shorter time, but also allows the desired tension to be adjusted automatically.

In an alternative embodiment of the invention, a force gauge integrated in the packaging device (20) or portable is used to measure the tension.

In the double wrap packaging method, the product is first placed in the packaging device (20) in a suitable position. In the preferred embodiment of the invention, the product to be packaged and the packaging material are aligned on top of each other and placed on both of the rotating elements at the same time. In an alternative embodiment of the invention, the packaging material is not placed on the rotating elements together with the product to be wrapped. At the end of the winding process, the packaging is made by passing it around the wrapped product.

In the double wrap packaging method, tensioning is done in the b method step. In the preferred embodiment of the invention, the tension is provided by the upper oppression spindle (3) positioned on the packaging device (20). Making a tight winding is one of the essential technical solutions of the method. The tension created by the winding made with the double winding model ensures that the joints are also stretched outwards. This tension in the joints prevents folding or breaking, and thus the inward elevation caused by the fractures and the damage caused by this elevation (Tepe) are prevented. Protecting the integrity of the product by wrapping it tensely during winding increases the winding quality, increases the waiting time of the packaged product in the packaged state, and reduces the damage it may suffer during transportation. The more friction the product experiences in the package, the shorter its lifespan and creates a high standard deviation rate among the quality used by the end users.

In the preferred embodiment of the invention, the formation of the double roll mentioned in method step C is in the fixed rotation axis (D1 ) of the fixed double shaft assembly (1 ) in the packaging device (20); It is obtained by rotating the movable double shaft assembly (2) on the movable rotation axis (D2) simultaneously or sequentially in the same direction, either clockwise or counterclockwise.

The scope of protection of the invention is specified in the attached claims and cannot be limited to what is described in this detailed description for exemplary purposes. Because it is clear that a person skilled in the art can present similar embodiments in the light of what has been described above without departing from the main theme of the invention.
