Description

Vessel Automatic Molding Machine {.}

The present invention relates to a container automatic molding machine for automatically forming a container of natural materials, and more specifically, a container automatic molding machine for continuously producing a container automatically as a mixture of kneaded material is automatically introduced into a mold and transported. It is about.

In general, containers produced using synthetic resin as raw materials can be mass-produced, so they are relatively inexpensive and are widely distributed.However, when food is stored for a long time in the container, there is a bad smell caused by the toxicity of synthetic resin. In recent years, the trend is to prefer containers made of ceramics.

In addition, the above-mentioned synthetic resin containers are recyclable, but a large amount of containers are not recycled and disposed of, but if incinerated, they pollute the air, and when buried, they do not decompose even after a long time. It is the main cause of soil pollution.

Accordingly, container manufacturers are investing a lot of research funds in the development of containers that decompose naturally even after disposal.

According to the patent application No. 6605 of 1999, a process of making a container by selectively combining a natural adhesive corn starch or potato starch with agricultural products by-product chaff or wood by-product sawdust is shown in detail.

That is, after washing chaff or sawdust cleanly, the water content is dried to 98%, mixed with 20% by weight of starch and 80% by weight of water, and then stirred for a predetermined time so that the starch mixed with water is uniformly mixed, and then the mixture In order not to burn, it heats up to 100 degreeC and matures.

When the mixture is heated, the mixture is stirred so as not to agglomerate to form a paste having a certain viscosity. Then, the paste is put into dried chaff or sawdust, stirred for a predetermined time, dried to 98% of moisture, and then finely made to have a particle size of 0.01-0.1 mm. Crush.

Thus a uniformly stirring the pulverized chaff or sawdust powder 85 wt%, water 5% by weight, a coating of rosin 10% by weight, after then inject the mixture into the molding machine 100 from 300 ℃ at a pressure of 5kg / cm ² 10 - By pressing for 20 seconds to form the container, a container using natural materials is obtained.

However, as described above, a molding machine for molding a container by applying a constant pressure in a state in which a mixture is introduced into a molding machine and then heated, has the following problems.

First, productivity is reduced because the container is molded by the number of molds in the molding machine by the operation of opening the mold after the molding is completed after molding for a predetermined time in a state in which the mixture is put into the mold in the open state of the molding machine.

Secondly, in order to solve the first problem, since a large number of expensive molding machines had to be provided, a large amount of equipment cost was required, which made it impossible for a relatively small and medium-sized company.

Third, since a large area of factory site is required to install several molding machines, a lot of facility investment costs are required, as well as a large number of personnel are required to manage and operate the molding machine, which leads to a large labor cost.

Fourth, when producing a large amount of containers at the same time in different molding machines, there is a limit in maintaining the uniformity of the product because the precision of the molded article varies depending on the molding conditions and the mold state of each molding machine.

The present invention has been made to solve such a conventional problem, the upper and lower molds are configured to be moved along a predetermined trajectory, so that the molds are mutually opened on the inlet side of the mixture and the ejection side of the container, and the mold slowly on the molding side. It is an object of the present invention to provide a molding machine capable of continuously forming a container of natural materials by applying a predetermined pressure while being closed.

On the other hand, in the present invention and the take-out means for withdrawing the molded container from the lower core 23 while moving at the same speed as the feed rate of the lower core is installed on the take-out side of the container to configure the production line of the container as an automated line and It is further provided with a conveying conveyor (35) which is installed in close proximity to the lower core and conveys the container taken out from the ejecting means to the next process.

9 and 10, the take-out means includes a frame 36 provided between the lower core 23 and the conveying conveyor 35, a slider 37 provided on the frame so as to be movable horizontally, and the frame and A horizontal cylinder 38 provided between the sliders to horizontally move the slider, a picker 40 mounted on the slider so as to be lifted and absorbing the container 39, and a vertical cylinder mounted to the slider to lift the picker ( 41).

At this time, in the case of installing the pickers 40 installed in the slider 37 in two rows or more in multiple stages, the container 39 of several rows may be simultaneously adsorbed from the lower core 23 and transferred to the conveying conveyor 35 side. It becomes possible.

Air nozzles 43 and 44 for removing foreign substances remaining in the upper and lower cores 23 and 25 by high pressure are provided at the point after the ejection position of the container 39, and the base 1 Is wrapped by a cover 42 as shown in FIG.

Referring to the operation of the present invention configured as described above are as follows.

Figure 1 is a schematic diagram showing the production line of the natural container, the chaff or sawdust clean and mixed with 80% by weight of water starch 20% by weight in a dry state up to 98% water content after stirring for a certain time After the first pretreatment process of heating the mixture to 100 ° C. to prevent it from burning, and then aging it to make a paste, paste the paste with a certain viscosity into dried chaff or sawdust and stir for a certain period of time until the moisture content reaches 98%. After drying, the grinding process is performed to finely grind to have a particle size of 0.01-0.1 mm.

The crushed chaff or sawdust powder 85% by weight, 5% by weight of water, 10% by weight of rosin as a coating material is evenly mixed and the mixing and dispensing process is introduced into the molding machine. With reference to the accompanying drawings for a molding process for continuously forming a container by the description will be described in more detail.

As shown in FIG. 4, when the rotary valve 47 is rotated while the mixture 46 is filled in the hopper 45 through the mixing and dispensing process, the mixture 46 in the hopper 45 is connected to the lower core 23. A certain amount is put into the lower mold.

The amount of the mixture introduced into the lower core 23 as the rotary valve 47 is driven may be controlled by the control unit.

While the cores 23 are sequentially moved along the lower feed chain 9 in a state where the mixture is injected into the lower mold in the lower core 23 continuously at the input position of the mixture 46 according to the driving as described above. Since the roller bearing 34 rotatably installed on the bottom surface of the lower core 23 moves in a state of being connected to the heating means 30b, the plurality of heat transfer media 32 fixed to the lower core 23 are heated. It is conveyed in the state closest to (30b) to prevent the wear phenomenon due to the heat transfer medium 32 is connected to the heating means 30b in advance, whereby the mixture 46 injected into the lower core 23 is molded Maintain a temperature appropriate to the temperature.

At this time, the upper core 25 is moved at the same speed as the lower core 23, the upper core 25 is located in the top dead center.

That is, the protruding rods 25a protruding on both sides of the upper core 25 are fitted in the track grooves 26a of the upper rail 26. In the transfer section of the upper core 25, the track grooves 26a are upper portions. The upper core 25 is located at the top dead center because it forms the same orbit as the trajectory of the transfer chain 8.

However, when the upper core 25 continuously moves along the track groove 26a and reaches a position where the upper core 25 is integrated with the lower core 23, the track groove 24a of the lower rail 24 is moved to the upper conveying chain 8. The upper core 25 is gradually lowered because it is different from the orbit.

That is, since the lower core 23 fixed to the lower conveying chain 9 is conveyed along the track groove 24a of the rectangular lower rail 24, the lower core 23 is always conveyed horizontally at any position. The upper core 25 which is mounted to the upper transfer chain 8 to be lifted and lowered along the upper rail 26 has the upper rail 26 lowered in the forming section S. The lower section S1 and the forming section S and the upper section S2 are provided to be integrated with the lower core 23 so that the upper core 25 gradually descends while moving the lower section S1 to lower the lower core. A combination with (23) will be made.

As described above, when the upper core 25 is lowered along the downward section S1, the guide rods 29 are fixed to both sides of the upper core 25 so that the guide rods 29 are formed at each of the upper transfer chains 8. It is fitted in the guide hole (27a) of the guide piece 28 mounted for each unit, and gradually descends vertically. The guide rod (29) extends to the lower portion of the upper core (25) and extends downwardly. Since the 29 is inserted into the guide hole 23b formed in the lower core 23, the molding of the container is performed while the combination of the lower core 23 and the upper core 25 is made accurately.

In this way, when the lower core 23 and the upper core 25 are completely formed, when they reach the forming section S, the heat transfer medium 31 of the upper core 25 is provided in the forming section S. Since it moves to the state closest to (30a), the molding is made for about 15-20 seconds at the molding temperature of 130-180 ℃ while moving the molding section.

When the lower core 23 and the upper core 25 moves in the molding section S by the operation as described above, the molding of the container 39 is completed and the upper core 25 reaches the upper section S2. The upper core 25 is separated from the lower core 23 because the protruding rods 25a protruding to both sides of the upper core 25 and inserted into the track grooves 26a pass through the track grooves in the upward section. As described above, the guide rod 29 is vertically raised along the guide hole 27a of the guide piece 28 until the upper core 25 reaches the top dead center.

When the molding of the container is completed and the lower core 23 moves horizontally to reach the ejection position while the upper core 25 is raised to the top dead center, the slider 37 moves to the ejection position by driving the horizontal cylinder 38. As the vertical cylinder 41 moves and moves the picker 40 downward while moving, the picker 40 moves the lower core 23 while the slider 37 moves at the same speed as the feed speed of the lower core 23. At the same time, the container 39 is sucked up, and at the same time, the vertical cylinder 41 is driven to rise to the top dead center, so that the container is taken out.

After the extraction of the container 39 is completed, the slider 37 moves quickly to the right side in the drawing by driving the horizontal cylinder 38 and at the same time the vertical cylinder 41 is driven to lower the picker 40. As a result, the container 39 adsorbed on the picker 40 can be seated on the conveying conveyor 35. Accordingly, the state of the container seated on the conveying conveyor 35 can be visually identified or a camera (not shown) Defective product is identified by the coordinate recognition and only the good product is packaged in the next process.

Continued rotation of the rotating shaft (2) (3), the upper core 25 is turned to the upper side, the lower core 23 is turned to face the lower side to reach the debris removal position air nozzles 43, 44 Since high pressure air is injected through the foreign matter remaining in the upper core 25 and the lower core 23 is removed, the container can be continuously formed.

What has been described so far has described the process of adding, forming and taking out the mixture 46 using one phase and the lower cores 23 and 25, and the upper and lower cores 23 ( As 25) moves at the same speed, the mixture 46 is continuously introduced into the lower core 23 in the hopper 45, thereby enabling continuous molding of the container.

As described above, the present invention has the following advantages over the conventional molding machine.

First, as the mold is automatically closed or opened according to the continuous movement of the upper and lower cores 23 and 25 mounted on the upper and lower transfer chains 8 and 9, the molding operation is continuously performed. Minimize cycle time by forming, thus maximizing productivity.

Second, it is possible to continuously mass-produce containers using one molding machine, so it can be applied to relatively small and medium-sized companies that do not have abundant capital.

Third, since a large number of containers can be produced within a short time even if one molding machine is installed, it can be applied to a small and medium-sized company with a narrow factory site, and labor cost can be saved according to the management and operation of the molding machine.

Fourth, since the mass production using the same molding machine it is possible to maintain a constant precision of the molded article.
