4 and 5, the organic manufacturing apparatus according to the preferred embodiment of the present invention is mounted on the fixing means 100 and the fixing means 100 so that the mold 230 is mounted on one side thereof A rotating means 200 including a hollow shaft 210 and a hollow body of the shaft 210 in a vacuum state so as to vacuum-suck the primary molded vessel 400 fitted in the form- And a vacuum unit 300 installed therein. Hereinafter, the vessel 400 refers to a vessel that is in a state for smoothing the surface after primary molding.

4 and 6, the fixing means 100 is a means for fixing the shaft 210 of the rotating means 200. The fixing means 100 includes a stationary frame 110 to which the shaft 210 can be fixed, And a bearing 120 mounted on the shaft 110 and through which the shaft 210 passes.

2, the fixed frame 110 is provided with a pair of horizontal bars disposed at regular intervals so as to stably support the front portion and the rear portion of the fixed frame 110, One or more horizontal bars may be provided, and in the case of one bar, the shaft 210 may be mounted in the longitudinal direction of the bar.

In addition, the bearing 120 is mounted to the fixed frame 110 to ensure the rotation of the shaft 210 disposed through the shaft.

4 to 6, the rotating means 200 is a means for rotating the formwork 230 mounted on the front of the shaft 210 and the bowl 400 and is fixed to the fixing means 100 so as to be rotatable A mounting member 220 mounted on the front side of the shaft 210, a mold 230 gripped by the mounting member 220, a wheel 240 for rotating the shaft 210, And a power source 250 installed to operate the motor 240.

Here, the shaft 210 is fixed to the fixed frame 110 of the fixing means 100, and is disposed across a pair of horizontal bars of the fixed frame 110 arranged at regular intervals, for example, as shown in FIG. 4, (120). The shaft 210 has a hollow interior whose both sides in the longitudinal direction are opened. A vacuum means 300 is provided to make the inside of the hollow portion vacuum by the vacuum means 300, and a detailed description thereof will be given later. Here, the front side portion of the shaft 210 has a flange 211 for fixing the mounting member 220 as shown in Figs. The insertion member 330 is inserted through one opened surface of the shaft 210. In order to limit the insertion length of the insertion member 330, (Not shown) is machined on the inner surface of the shaft 210 so as to be caught. The engaging jaw may be formed so as to protrude only on a part of the shaft 210. The inner diameter of one side of the shaft 210 and that of the other side may be different from each other with respect to the engaging jaw.

4, 6, and 9, the mounting member 220 is fixed to the distal end side portion of the shaft 210, and is a member holding the mold 230. Fig. The mounting member 220 includes a body 221 fixed to the tip side portion of the shaft 210, for example, a flange 211, a body 221 mounted on the body 221 to reciprocate toward the center of the body 221, And has a plurality of jaws 222 and a rotation hole 223 mounted on the body 221 to reciprocate the jaws 222. Here, the reciprocating motion of the jaw 222 is achieved by inserting a wrench 224 into the rotary tool 223 and rotating the wrench 224 clockwise or counterclockwise as shown in FIG. 7A. As shown in Fig. 9, the mold 230 is detachably attached to the jowling 222 which reciprocates in this manner. Thus, the mold 230 can be firmly fixed by the reciprocating movement of the jaws 222, and can be easily separated. Therefore, the mold 230 can be easily and easily attached and detached.

9, the mold 230 is a member that is firmly fitted to the one side portion while being gripped by the mounting member 220. As shown in FIG. One side of the formwork 230 is processed to be in close contact with the surface of the container 400 to be fitted and the other side is processed into a shape to be gripped by the jowls 222 of the mounting member 220. The mold 230 has a hollow portion (not shown) penetrating from the insertion member 330 to the bowl 400 and a vacuum state formed in the hollow shaft 210 and the insertion member 330 through the hollow portion To the bowl (400). Of course, it is a matter of course that a part of the insertion member 330 is inserted into the hollow part of the mold 230 so as to be closed for vacuum maintenance, and this will be described again in the description of the insertion member 330 described later.

The molds 230 are formed in various shapes depending on the type and size of the container 400 and can be in close contact with the inner or outer surface of the container 400. Of course, since the bowl 400 is attracted to the mold 230 by the vacuum pressure, it is not necessarily required to be fitted with the interference fit. However, since the shape of the bowl 400 may be unstable during the cutting operation of finishing the surface, So as to be brought into close contact with the surface. A close contact tightening ring (not shown) is disposed on the surface of the mold frame 230 in close contact with the vessel 400, which is a closed curve or an open curve in the circumferential direction and at least one in the depth direction. At least one contact ring is disposed on the concave inner surface of the concave mold 230 when the inner surface of the container 400 is trimmed. When the outer surface of the container 400 is trimmed, At least one contact ring is arranged in the depth direction. Further, by making the protruding height of the contact ring along the depth direction of the mold 230 different, it is possible to prevent the container 400 from being in close contact with any one or more of the contact rings when the size of the container 400 is slightly different, . At this time, the vessel 400 is primarily aligned with the center of the mold 230, and is perfectly concentric with the suction by the vacuum means 300. Of course, the elasticity of the contact ring is such that when the container 400 is attracted to the mold 230 by the vacuum of the vacuum means 300, the mold 230 and the container 400 are centered, And the surface of the vessel 400 can be brought into close contact with each other.

The wheel 240 is mounted to rotate the shaft 210 as shown in FIGS. 4 and 5, and is installed to rotate by receiving power from the power source 250.

Further, the power source 250 is provided to rotate the wheel 240, and may be a belt, or may be a belt other than a belt, as an example structure for transmitting power.

As shown in FIG. 4, the vacuum means 300 includes a connection pipe 310 having one side mounted to a vacuum generating source (not shown), a rear side of the shaft 210 mounted with the other side of the connection pipe 310, And an insertion member 330 protruding outwardly from the mounting member 220 at a portion of the other side of the connecting member 320 inserted into the shaft 210. [

First, as shown in FIG. 4, the connection pipe 310 is installed by connecting a driving unit for generating vacuum and a connection member 320. And is connected to the driving source to draw the internal air of the shaft 210 to the driving source side through an intake operation. At this time, the air inside the shaft 210 moves to the driving source through the connecting member 320 and the connecting pipe 310.

4 and 8, the connecting member 320 is mounted at the rear of the shaft 210. One end of the connecting member 320 is connected to the hollow interior of the shaft 210, And a vacuum hole 321 formed therein. That is, when the connecting member 320 is mounted to the rear of the shaft 210, one opening of the vacuum hole 321 is connected to the inside of the shaft 210, and the other opening of the vacuum hole 321 is connected to the connecting pipe 310, Is hermetically mounted. Accordingly, when the driving source is operated, air in the shaft 210 is drawn through the connecting pipe 310 and the connecting member 320.

4, 5, 7A, 7B, and 9, the insertion member 330 is provided with a hollow having both side openings in the longitudinal direction, and most of the insertion member 330 is provided with the shaft 210 and the mounting member 220 And a part of the stomach is mounted so as to protrude outward from the mounting member 220. Here, one side of the insertion member 330 is inserted up to the protruding jaw machined on the inner surface of the shaft 210, and the other side is inserted into the mold 230. That is, the hollow side portions of the insertion member 330 are installed to connect the inner hollow of the shaft 210 and the inner hollow of the mold 230, respectively. Here, the outer surface of the insertion member 330 is provided with at least one sealing member groove 331 formed in the circumferential direction for mounting a vacuum-holding sealing member (for example, an O-ring, not shown). Therefore, when the insertion member 330 is inserted into the shaft 210, the sealing member mounted on the at least one sealing member groove 331 formed in the longitudinal direction of the insertion member 330 and the inner surface of the shaft 210 are in close contact with each other And the vacuum state inside the shaft 210 is maintained. A sealing member groove 330 is also formed on a part of the insertion member 330 which protrudes outward from the shaft 210 or the mounting member 220 and a sealing member is mounted on the sealing member groove 331. Therefore, when the protruding part of the insertion member 330 is inserted into the hollow of the mold 230, the sealing member is brought into close contact with the hollow inner surface of the mold 230 to maintain the vacuum state inside the mold 230. The insertion member 330 is configured such that the outer diameter of the portion where the insertion member 330 is inserted into the mounting member 220 through the flange 211 of the shaft 210 is larger than the outer diameter of the portion where the shaft 210 is inserted, So that the portion can be firmly engaged with the jaw 222 of the mounting member 220.

The intake air generated in the driving source, the connecting pipe 310, the connecting member 320 and the shaft 210 reaches the mold 230 through the insertion member 330 and is brought into close contact with the mold 230 The intake air reaches to the container 400, and the container is firmly fixed to the container 230. The vacuum operation of the driving source is transmitted to the bowl 400 through the connecting pipe 310, the connecting member 320, the shaft 210, the insertion member 330 and the mold frame 230, So that it is possible to firmly fix the base 400. In addition, when the vacuum operation of the driving source is stopped, the container can be easily removed from the mold 230.

As described above, those skilled in the art will appreciate that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are to be considered in all respects as illustrative and not restrictive. The scope of the present invention is defined by the appended claims rather than the detailed description and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included within the scope of the present invention.
