Description

 Wet and Dry Mold Forming Equipment {PULP-MOLD FORMING APPARATUS}

The present invention relates to an apparatus for molding pulp mold, an environmentally friendly packaging container for packaging a product such as food or electronic products from a pulp solution, and more specifically, to improve the drying process structure and to shorten the working time to improve productivity. To control the quality parameters such as the surface roughness and / or thickness of the pulp mold and to easily produce pulp molded products having various surface roughness and thickness that can be used in various applications. will be.

Conventionally, synthetic resins such as styrofoam have been generally used as packaging containers for packaging electronic products or foods such as eggs. However, since synthetic resins are difficult to decompose, there is a problem of causing environmental problems. Recently, a tendency to manufacture packaging containers using wood pulp as an environmentally friendly packaging container that can be easily decomposed has been increased. Accordingly, an apparatus for pulverizing the pulp to make a pulp solution dispersed in a solution such as water, for example, and forming a packaging container (hereinafter sometimes referred to as 'pulp mold') of a desired shape from the pulp solution is conventionally used.

1 is a schematic flow chart showing a general dry pulp mold forming process. In the process of forming a pulp mold, as shown, a raw material solution is first prepared (1) a raw material such as deinking pulp is prepared (2), and a pulp solution is prepared by mixing water and the raw material (3). . Thereafter, the pulp solution thus prepared is subjected to three steps of heat drying and press molding in the pulp mold forming apparatus (4, 5, 6) to evaporate water vapor and then the product is completed (7). In the primary drying process (4), the lower mold having a generally concave shape is contained in the pulp solution tank so that a certain amount of pulp is accommodated in the recess of the mold. The lower mold then stops or rises slightly, and the paper mold pulp is formed by first sucking water in the pulp solution through the vacuum suction device in the lower mold. Then, the upper mold of the convex shape corresponding to the shape of the recess of the lower mold is lowered to pressurize the pulp between them, and at the same time, the paper pulp mold between the upper and lower molds is first applied by applying heat of about 250 ° C. Dry while molding. The pulp mold formed after the primary drying is transferred to the secondary drying step (5), in which the pulp mold becomes thinner as it is further pressurized and heated by upper and lower molds similar to the primary. Water contained in the pulp mold is evaporated as water vapor. Finally, a similar tertiary drying process 6 may be performed to produce a dried product having a desired thickness.

However, the above-described dry or hot mold drying method has some prominent problems.

First, the distance that the upper mold should be moved to the lower mold located below the primary upper mold was much longer than the distance that the upper mold should move to the lower mold in the secondary or tertiary process. It takes a lot of time throughout the drying process, and the secondary and tertiary drying process, which has relatively short vertical movement distance, should work in the same time in keeping with the primary drying process. The process also took more time than needed.

Secondly, thick and thick products (more than 2.5mm) cannot be handled because they are not sufficiently dried, and they require a lot of production time even for relatively thin products. It has a disadvantage that can only be expensive. More specifically, in the apparatus shown in Fig. 1 or 2, the first to third drying process (4, 5, 6), (12, 14, 16) are each for a certain time, and In the continuous dry pulp mold production process, the time spent in each drying process determines the productivity. Currently, it is known that each drying process takes about 30 seconds or more. In the conventional dry drying method, for example, in the case of a relatively thin product (1 to 2.5 mm) without requiring much surface roughness, the required drying amount is satisfied after the third compression step of 30 seconds for each process, but the surface roughness is satisfied. This results in an unnecessarily long production time, which is better than necessary, in order to meet the required drying volume, which in turn can lead to higher unit prices and to compete with the bulk low-priced products of certain countries in the international market for pulp packaging. It was a factor

For this reason, in the conventional dry or hot mold pulp mold forming apparatus, the operation structure of the drying process can be improved, or the working time can be shortened by introducing an appropriate drying system such as a complex drying process according to the surface roughness and the drying amount required by the product. There has been a need for new technologies that can increase productivity.

The present invention is devised to solve the problems of the conventional pulp mold forming apparatus described above,

An object of the present invention is to provide a wet and dry mold molding apparatus that can reduce the working time and the number of molds simultaneously by improving the movable structure of the drying process.

It is still another object of the present invention to first obtain an intermediate pulp mold which has been somewhat dried by a hot mold drying process, and then to introduce a separate drying process, such as a wet (hot air) drying process for the final pulp mold, in various thicknesses and / or Another object of the present invention is to provide a wet and dry mold molding apparatus capable of significantly shortening the production time regardless of pulp mold having a surface roughness.

The above objects are achieved by a top feed wet and dry mold forming apparatus provided according to one aspect of the present invention. This apparatus forms a paper pulp mold from a raw material pulp solution in the form of an aqueous solution supplied from the top, press-molded the paper pulp mold three times, and then wet or hot air drying to obtain a desired thickness and dryness.

It may be configured to include; hot air drying unit having a hot air drying chamber for.

According to one embodiment of the present invention, the primary upper mold is guided by a vertical transfer guide rod to be moved up and down by an up and down transfer cylinder, which is predetermined by a rotation cylinder including a motor driving unit or a rack and a pinion. It is preferred to configure it to rotate in position.

According to an embodiment of the present invention, the hot air drying unit includes at least two hot air drying chambers, the distribution for supplying alternately the intermediate pulp mold discharged from the hot mold drying unit to each of the at least two hot air drying chambers It is preferable to further include a conveying unit.

In addition, a door that can be opened and closed by an opening and closing device that automatically detects and closes a pulp molder is installed at an entrance side and an outlet side of the drying chamber, and the door is closed in a hot environment and an external room temperature in the drying chamber. By blocking the environment of the chamber, preventing heat loss from the drying chamber, and on the other hand, the pulp mold can be opened to allow passage from the inlet to the drying chamber or from the drying chamber to the outlet. It is preferable.

Hereinafter, with reference to the accompanying drawings a specific embodiment of the present invention will be described in more detail.

2 is a more detailed schematic view for explaining the principle of the so-called dry pulp mold forming apparatus 10 using a conventional hot mold drying method. As shown, the conventional dry pulp molding apparatus 10 may be largely divided into primary mold parts 11 and 12, secondary mold parts 13 and 14, and tertiary mold parts 15 and 16. have. Each mold part includes the shape parts 111, 121, 131, 141, 151, 161, and control assemblies 112, 122, 132, 142, 152, and 162 in common. The shape portion is formed with a concave portion and a convex portion in which the lower mold and the upper mold are engaged with each other to produce a pulp mold having a predetermined shape. The control assembly is equipped with a vacuum suction device, a heater and an air blow. Each part of the device is configured to be fixed to and move relative to the overall frame 17, in which only a part of it is shown in the figure.

On the other hand, in the apparatus 10, as shown generally, the primary lower mold 11 and the primary and secondary molds 12, 14, and 16 are hydraulic cylinders 116 such as, for example, using pneumatic pressure. , 126, 146, 166 are mounted to the frame 18 so as to be movable in the vertical direction at a horizontally fixed position on the frame 18. Each mold (11, 12, 14, 16) is connected to the drive shaft (113, 123, 143, 153, 163) of the hydraulic cylinder receives the driving force, the auxiliary guide shaft (114, 115; 124, 125; 144, 145) , 164, and 165 may be stably connected relative to the frame 18. The secondary lower mold 13 and the tertiary lower mold 15 are fixed on the conveying plate 172 at a vertically fixed position on the frame 18 and slid on the conveying guide 174 to thereby reciprocate the conveying device 17. Can be reciprocated left and right, i.e. in the horizontal direction.

The secondary and tertiary lower molds 13 and 15 can reciprocate between two positions, namely the left position and the right position. That is, when moved to the left position, the secondary lower mold 13 is positioned below the primary upper mold 12 and the tertiary lower mold 15 is positioned below the secondary upper mold 14. At this time, under the third upper mold 16, a device such as a conveyor for discharging the final product may be located. And the right position is a state shown in the figure, the secondary lower mold 13 is located below the secondary upper mold 14 and the lower third mold 16 is positioned below the tertiary upper mold 16. At this time, the primary lower mold 11 is positioned below the primary upper mold 12.

At the bottom of the device 10 is a raw pulp solution tank 19. The primary lower mold 11 may be lowered to be immersed in the tank 19 so that the pulp solution may be accommodated in a recess formed in the mold, that is, the shape 111. After receiving the pulp solution, the primary lower mold 11 rises to the top of the tank to some extent, and the vacuum suction device of the control assembly 112 is operated to remove the water in the pulp solution. Thereafter, the primary upper mold 12 is lowered, and accordingly, the shape 111 of the primary lower mold 11 and the shape 121 of the primary upper mold 12 engage with each other. The wet pulp in between is pressurized to have a thickness set as the thickness of a predetermined primary pulp mold. At the same time, the heaters in the control assemblies 112 and 122 are operated to heat, for example, to a temperature of about 250 ° C.

When the primary molding and drying steps are completed, the vacuum suction device in the control assembly 122 of the primary upper mold 12 is operated to ascend with the pulp mold adsorbed, and the primary lower mold 11 is again a raw pulp solution. It is lowered into the tank 19 to receive the raw pulp solution. After the primary upper mold 12 is raised, the transfer device 17 moves the transfer plate 172 to the left position so that the secondary lower mold 13 is positioned below the primary upper mold 12. Then, the operation of the vacuum suction device is stopped in the primary upper mold 12 and the air blower is operated to drop the pulp mold onto the shape 131 of the secondary lower mold 13. Thereafter, when the transfer device 17 is operated to move the transfer plate 172 to the right position, the secondary lower mold 13 is now positioned under the secondary upper mold 14. Thereafter, the secondary upper mold 14 descends to the secondary lower mold 13 on which the pulp mold is mounted, thereby compressing about 33% and drying about 33% for the primary molded pulp mold. The secondary pulp mold may be formed. Meanwhile, while the secondary pulp mold is formed by the secondary upper and lower molds, another primary pulp mold is formed through the same process as described above by the primary upper and lower molds.

When the secondary forming and drying steps are completed, the vacuum suction device in the control assembly 142 of the secondary upper mold 14 is operated to rise while absorbing the completed secondary pulp mold to about 66%. After the secondary upper mold 14 is raised, the conveying device 17 moves the conveying plate 172 to the left position so that the empty upper lower mold 13 adsorbs another primary pulp mold. It is located below the mold 12. Then, the first upper mold 12 is dropped onto the shape portion 131 of the secondary lower mold 13, and the secondary molding step by the secondary upper and lower molds is performed as described above.

Meanwhile, when the transfer device 17 moves the transfer plate 172 to the left position, the third lower mold 15 is positioned below the secondary upper mold 14 which is adsorbing the secondary pulp mold. Then, the pulp mold is dropped from the secondary upper mold 14 onto the shape portion 151 of the tertiary lower mold 15. Thereafter, when the transfer device 17 is operated to move the transfer plate 172 to the right position, the third lower mold 15 is now positioned below the third upper mold 16. Then, the third upper mold 16 is lowered to the third lower mold 15 on which the pulp mold is mounted, thereby compressing about 33% and drying about 33% of the secondary molded pulp mold. In other words, the final tertiary pulp mold can be formed, that is to say 100% compressed and 100% dried. The final pulp mold may be discharged away from the tertiary upper mold to the discharge conveyor (not shown) after the transfer plate 172 moves back to the left position.

As described above, conventionally, the distance that the first upper mold has to move to the first lower mold located below is not only considerably longer than the distance that the upper mold has to move up and down in the second process or the third process. Therefore, the secondary and tertiary drying processes, which have relatively short vertical movement distances, must be operated within the same time as the primary drying process. Although time was required to produce the product, as described above, by varying the operation method of the primary drying step, productivity can be greatly improved by reducing the number of molds as well as reducing the working time.

In addition, in the case of relatively thick products (about 2.5mm or more), the conventional dry method is difficult to produce enough because it is difficult to secure a certain strength, and the hot air drying method is a relatively high-quality product due to poor surface roughness Although there was a limit in making the present invention, the present invention is configured to use the improved dry method and hot air drying method in combination with the dry method is responsible for the entire surface roughness required for the product and a part of the required dry amount, the hot air drying method By taking charge of the remainder of the required amount of drying, it was possible to produce a thick pulp product with good surface roughness and constant strength. In addition, for relatively thin products (less than about 2.5 mm) without requiring very high quality surface roughness (the best good surface roughness that can be obtained in conventional dry methods), it is possible to reduce the step-by-step time according to the roughness in the dry method. At the same time, by shortening the amount of drying by the reduced time by a hot air drying method it is possible to shorten the production time of the product by the time reduced in the dry process.

As described above with reference to FIGS. 1 and 2, the present invention molding apparatus 100 forms a paper pulp mold in a uniform shape from a raw material pulp solution in the form of an aqueous solution, and presses the paper pulp mold over three times. It is a wet and dry mold forming apparatus for producing pulp mold of a desired shape having a quality parameter such as desired thickness or surface roughness by molding and drying with hot air.

As shown in FIG. 3, the apparatus 100 includes a primary upper mold 314, a primary lower mold 316, a transfer plate 34, a secondary upper mold 322, and a secondary lower mold 326. ), And may include a third upper mold 332.

The primary upper mold 314 forms a paper pulp mold by accommodating the supplied quantity of pulp solution and absorbs water to form a paper pulp mold, and then rotates the paper pulp mold 180 ° while adsorbing the paper pulp mold. It is a mold that is transported down again. The primary upper die 314 is provided with vacuum adsorption means for adsorbing moisture absorption and paper pulp mold.

The primary lower mold 316 accommodates the papermaking pulp mold conveyed by the primary upper mold 314, engages with the primary upper mold 314 to pressurize and heat the primary pulp mold. It is a mold for forming.

As shown in FIGS. 4A to 4D, the primary upper mold 314 is guided by a vertical transfer guide rod and moved up and down by an up and down transfer cylinder 313, and connected to the up and down transfer cylinder 313. And, it is characterized in that it is coupled to rotate by 180 ° in a predetermined position by a rotation cylinder 315 including a motor driving unit or rack and pinion. 4A shows the primary upper mold 314 forming a paper pulp mold from the supplied raw pulp solution. 4B shows a state in which the primary upper mold 314 is rotated by 90 ° by the rotation cylinder 315 after a predetermined distance from the hopper 312 by the vertical transfer cylinder 313. 4c shows a state in which the rotation is completed and rotated 180 °. 4D illustrates a process in which the primary upper mold 314 and the primary lower mold 316 mesh with each other to form a primary dried pulp mold. Thereafter, the primary upper mold 314 is returned to the hopper 312 through the reverse process, and the primary lower mold 316 is transferred laterally by the transfer plate, that is, to the position below the secondary upper mold. Then the same steps as in the above procedure are repeated.

This primary lower mold 316 is mounted on the transfer plate 34. The transfer plate 34 is a device for laterally transferring the primary lower mold containing the primary dried pulp mold, and may be driven by a pneumatic cylinder and guided by a horizontal transfer guide. Those skilled in the art will readily understand that such a transfer plate 34 is similar to the structure of the transfer plate described with reference to FIG.

The second upper mold 322 is lowered to the first lower mold 316 transferred to the side to press-mold the first dried pulp mold and remove moisture to form a second dried pulp mold. The dried pulp mold is adsorbed and raised.

The secondary dried pulp mold adsorbed and raised by the secondary upper mold 322 is dropped to the secondary lower mold 326 moved by the transfer plate 34 below. The secondary lower mold 326 is disposed to be horizontally transferred together with the primary lower mold, and is a mold for accommodating the secondary dried pulp mold from the secondary upper mold 322.

The secondary dried pulp mold housed in the secondary lower mold 326 is conveyed laterally by the transfer plate 34 to the position below the tertiary upper mold 332. The tertiary upper die 332 is lowered to the secondary lower die 326 which has been transferred downward by the transfer plate 34. The secondary dried pulp mold housed on the secondary lower mold 326 is press-molded and water-removed by joining the tertiary upper mold 332 and the secondary lower mold 326 with each other, thereby tertiary dried pulp. It is formed into a mold. The formed tertiary dried pulp mold is adsorbed and lifted by the tertiary upper mold 332, and may then be dropped on a conveying means such as the conveying conveyor 37. The tertiary dried pulp mold may then be transferred to a hot air drying apparatus by a transfer conveyor 37.

In the present invention, a complete pulp mold product is not manufactured by these first to third mold processes, and 100% compression ratio for quality parameter set values such as thickness and surface roughness is achieved while the dry state is 100%. No has the feature. For example, only about 50% of drying can be achieved. Accordingly, the time required by heat drying in each mold process can be greatly saved, so that the speed of the entire process can be increased.

The intermediate pulp mold discharged through the transfer conveyor 37 in the hot mold drying units 31, 32, 33 is completely dried by the subsequent hot air drying unit 27. The hot air drying unit 27 sequentially stores the intermediate pulp molds formed in the hot mold drying unit, applies the hot pulp at a predetermined temperature while sequentially transferring the plurality of intermediate pulp molds stored therein, and then completely dries them. And a hot air drying chamber 274 for sequentially discharging the final pulp mold. The drying chamber 274, its entry portion 272 and the discharge portion 276 are dried in a state in which the pulp mold is continuously moved by one conveyor. Although only the hot air blower 278 is shown in the drawing, hot air may be supplied from the hot air blower 278 into the drying chamber 274 through an appropriate piping facility.

The length of the hot air drying unit 27 is preferably selected so as not to slow down the discharge rate of the intermediate pulp mold that is molded and dried in the hot mold drying units 31, 32, and 33.

In addition, in a preferred embodiment of the present invention, by installing a plurality of hot air drying unit 27 enables a facility in a narrow space. Although the illustrated example is illustrated as including two hot air drying chambers 274, the present invention is not limited to two. At this time, between the hot mold drying unit 31, 32, 33 and the hot air drying unit 27, alternately supplying the intermediate pulp mold discharged from the hot mold drying unit to each of the at least two hot air drying chambers 274. Dispensing transfer unit 25 is further installed. As shown, the dispensing conveying unit 25 may be configured with a forward conveying unit 252 which continues to feed in the direction in which the pulp mold proceeds, and a transverse conveying unit 254 for changing the direction toward the other drying chamber. . However, the present invention is not limited to the illustrated example, for example, the configuration of the distribution transfer unit 25 using a rotating mechanism may be possible.

The intermediate pulp mold transferred from the hot mold drying unit through the distribution transfer unit 25 arrives at the drying chamber entrance 272. Opening and closing doors are provided on the inlet and outlet sides of the drying chamber 276. The opening and closing door normally serves to prevent heat loss from the drying chamber 276 by blocking a hot environment in the drying chamber 276 and an environment of an external room temperature, while the pulp mold is formed from the inlet 272 to the drying chamber ( 276 may be opened to pass into or out of the drying chamber 276 toward the outlet 276.

The opening and closing door is a simple flexible member and may have a structure that is suspended so that the pulp mold can be opened by a force applied while moving. Preferably, for example, a pulp mold detection sensor, a programmable logic controller (PLC), and a pneumatic cylinder drive device, the switchgear (273, 275) for automatically operating by detecting the proximity of the pulp molder The chamber door may be opened and closed by).

Specifically, although not shown, it is preferable that the entrance port 272 is provided with a sensor such as an optical sensor for detecting the presence of the pulp mold at an appropriate position. The sensor detects that the pulp mold has arrived at the entrance port 272 and informs the controller of the pulp mold, and the PLC may control the chamber door opening and closing device 273 to open the chamber door. Accordingly, when the opening and closing device 273 opens the chamber door, the pulp mold arriving at the entrance 272 may be naturally transferred into the drying chamber 276 on the transfer conveyor.

Similarly, although not shown, a sensor for detecting the presence of the pulp mold is preferably installed near the discharge chamber door in the drying chamber 276. The sensor detects that the pulp mold that has completed the drying process while passing through the drying chamber 276 arrives near the discharge chamber door, and informs the PLC, and the PLC controls the switching device 275 to open the discharge side chamber door. can do. Accordingly, when the opening and closing device 275 opens the chamber door, the completed pulp mold may be naturally transferred from the drying chamber 276 to the outlet 276 on the transfer conveyor.

In addition to being controlled by an automatic control device including such a sensor and a PLC, the opening and closing operations of the opening and closing devices 273 and 275 can be set at a time that can be constantly set using a timer when the progress speed of the entire process is constant.
