That is, in the case of the servo motor forming the motor means 1032, when the rotation speed is rotated by a predetermined amount, the screw shaft 1036 is rotated by the predetermined rotation speed through the driving pulley 1042, the belt 1046, and the driven pulley 1044. The rotation of the screw shaft 1036 causes the grippers 1020a and 1020b to move in the width direction by a predetermined distance through the nut members 1038a and 1038b.

Accordingly, the controller 5000 can adjust the position of the grippers 1020a and 1020b by controlling the operation of the motor means 1032, and in this state, the cylinder means 1062a and 1062b of the bag fixing means 1060. ) To open the collectors 1023a and 1023b of the grippers 1020a and 1020b, and then place the vacuum bag P on the collectors 1023a and 1023b of the grippers 1020a and 1020b. The sound collecting units 1023a and 1023b are closed to fix the vacuum bag P to the grippers 1020a and 1020b.

In this case, the vacuum bag P is preferably fixed by the grippers 1020a and 1020b at a position slightly below the upper end thereof. The reason for this is that when the vacuum bag P is fixed according to the present invention, the vacuum bag P moves the contents inside while moving, to form a vacuum, and then to the inlet Pa of the vacuum bag P again. ) Must be sealed, so that the chute 2505 of the contents input section 2500, the contents sealing section 3000, and the like must enter the inlet Pa side of the vacuum bag P for this operation. The inlet Pa portion of the vacuum bag P is preferably mounted in advance so as to be positioned slightly above the grippers 1020a and 1020b.

On the other hand, the present invention is shown in Figure 26 a), b) as a modified embodiment, a structure in which the width adjusting means is modified differently.

The width adjusting means 1130 of the bag fixing part 1000 ′ shown in FIGS. 26A and 26B is provided with a motor means 1132 on the first pedestal 1010, and is fixed by the motor means 1132. A screw shaft 1136 fixed to the reverse rotation and a nut member 1138 screwed to the screw shaft 1136.

One end is rotatably connected to both sides of the nut member 1138, and the other end includes link members 1140a and 1140b rotatably connected to lower surfaces of the grippers 1020a and 1020b, respectively.

When the width adjustment means 1130 is the screw shaft 1136 to the forward and reverse rotation by the operation of the motor means 1132, which means that the nut member 1138 moves along the screw shaft 1136, The movement of the nut member 1138 pushes the grippers 1020a and 1020b to the left and right on the rail 1142 through the link members 1140a and 1140b.

The rails 1142 are fixed in the transverse direction on the first pedestal 1010, and a pair of sliders 1144a and 1144b are fitted to slide on the rails 1142, and the sliders 1144a ( Lower surfaces of the grippers 1020a and 1020b are interviewed on the upper surface of 1144b, respectively, and are connected to each other by fastening the bolts 1146 as illustrated in FIG. 26B.

Therefore, the left and right positions of the grippers 1020a and 1020b can be adjusted through the width adjusting means 1130.

In addition, the present invention is another modified embodiment as shown in Figure 27a), b), the structure is shown in which the width adjusting means is modified differently.

27a) and b), the width adjusting means 1160 of the bag fixing portion 1000 " is provided with a plurality of motor means 1162a and 1162b on the first pedestal 1010, and the motor means 1162a. And a nut member 1168 coupled to the screw shafts 1166a and 1166b, having a plurality of screw shafts 1166a and 1166b that are fixed so as to be rotated forward and reverse by 1162b).

The motor means 1162a and the screw shaft 1166a are for moving the grippers 1020a and 1020b back and forth, and the motor means 1162b and the screw shaft 1166b are used to grip the grippers 1020a and 1020b. It is for moving in the left-right direction. The motor means 1162b is mounted on a movable table 1172 that is movable on a separate rail 1170 provided on the first support plate 1010.

In addition, the nut member 1168 to which the screw shafts 1166a and 1166b are coupled passes through a screw hole 1182a to which the screw shafts 1166a is screwed and a circular cross-sectional portion 1184 of the screw shaft 1166b. Circular holes 1182b are formed.

Thus, when the screw shaft 1166a is rotated by the motor means 1162a, the nut member 1168 moves along the screw shaft 1166a, and the movement of the nut member 1168 is caused by the screw shaft 1166a. Through the gripper (1020a) (1020b) to move back and forth. In this case, the motor means 1162b is movable on the rail 1170 of the first pedestal 1010 forward and backward.

When the motor means 1162b is rotated, the screw shaft 1166b is rotated, which is gripper screwed through the left screw portion 1186a and the right screw portion 1186b provided in the screw shaft 1166b. The interval between the 1010a and 1020b may be narrowed or widened.

As such, the present invention can achieve the movement of the grippers 1020a and 1020b through various deformation structures.

And the rotary vacuum automatic packaging system 500 according to the present invention, as shown in Figure 28, by the gripper (1020a) (1020b) the envelope opening portion 2000 in a state in which both corners of the vacuum bag (P) is fixed When the central axis 615 is rotated by the operation of the drive source 610 for rotating the frame portion 600, the second disc portion 650 is rotated, the envelope fixing portion 1000 Rotate.

When the vacuum bag P is positioned at the bag opening part 2000, the rotation of the frame part 600 is temporarily stopped and the operation of the bag opening part 2000 is started.

As shown in FIG. 29, the envelope opening 2000 includes a pair of arms 2020a and 2020b located at both sides of the vacuum bag P, and the width opening means 2040 opens the envelope opening means. 2030a and 2030b are moved in close contact with both sides of the envelope P. As shown in FIG. In this process, in order to adjust the positions of the arms 2020a and 2020b, the controller 5000 operates the motor means 2044 of the width adjusting means 2040 to adjust the distance between the arms 2020a and 2020b. . That is, in the case of the servo motor constituting the motor means 2044, when the rotation speed is rotated by a predetermined amount, the driving pulley 2052, the belt 2056, and the driven pulley 2054 rotate the screw shaft 2046 by the predetermined rotation speed. The rotation of the screw shaft 2046 causes the arms 2020a and 2020b to linearly move in the width direction by a predetermined distance through the nut members 2048a and 2048b.

Accordingly, the controller 5000 may adjust the positions of the arms 2020a and 2020b by adjusting the rotation speed and the rotation direction of the motor means 2044, and in order to suck both sides of the vacuum bag P, As shown in Fig. 29, the suction port 2072 of the bag opening means 2030a and 2030b is brought into close contact with the vacuum bag P side.

Then, the controller 5000 opens the automatic shut-off valve 2084 provided in the vacuum hose 2082 of the vacuum source 2080 according to a predetermined program or by a manual manipulation of the controller 5000. Therefore, the vacuum pressure from the vacuum pressure generator 2080 extends to the suction port 2072, and the suction port 2072 sucks both sides of the vacuum bag P and opens them to both sides.

Therefore, the opening Pa of the vacuum bag P is opened through this process, and when the opening Pa of the vacuum bag P is opened in this manner, the width adjusting means 2040 is the arm 2020a. ) 2020b is moved away from the vacuum bag P to greatly enlarge the entrance Pa.

The motor means 2044 of the width adjusting means 2040 also operates in this process to widen the gap between the arms 2020a and 2020b. Accordingly, since the arms 2020a and 2020b are moved so as to have a slightly wider space therebetween, as shown in FIG. 29, the vacuum bag P having both sides attached to the suction port 2082 is the arm 2020a. By the movement of 2020b, the entrance Pa expands more naturally and expands to form a food input space.

In addition, when the vacuum bag P is pulled to both sides in this process, the bag fixing part 1000 moves the clamps 1020a and 1020b closer to each other to further open the opening Pa of the vacuum bag P. It can be done smoothly.

Since the suction port 2072 is made of a flexible flexible tube having an elastic force, it is to minimize the damage of the vacuum bag (P) in the process of widening the inlet (Pa) of the vacuum bag (P).

On the other hand, the present invention is a modified embodiment as shown in Figures 30 and 31, the width adjustment means 2130 is shown a structure that is modified differently.

The width adjusting means 2130 is provided with a motor means 2132 on the second pedestal 2015, the screw shaft (2136) and the screw shaft (fixed so as to be rotated forward and backward by the motor means 2132 ( 2136 includes a plurality of nut members 2138a and 2138b respectively coupled to rear ends of the arms 2020a and 2020b.

The screw shaft 2136 is formed with a left screw portion and a right screw portion, respectively, which are screwed to the nut members 2138a and 2138b fixed to the respective arms 2020a and 2020b so that the motor means ( When 2132 is rotated, the screw shaft 2136 is rotated, which is through the arm 2020a through nut members 2138a and 2138b respectively coupled to the left and right screw portions provided on the screw shaft 2136. It is possible to change the spacing between the (2020b) to narrow or wide.

As described above, the present invention can effectively achieve the movement of the arms 2020a and 2020b through various deformation structures.

In addition, a rail 2140 is formed on the upper portion of the second pedestal 2115 while maintaining coaxiality with the screw shaft 2136, and the rail 2140 is the arm 2020a as described with reference to FIG. 29. The arm 2020a and 2020b through the sliders 2142a and 2142b to move left and right on the rails 2140 according to the rotation of the screw shaft 2136. It is.

When the vacuum bag P is pulled to both sides by the bag opening 2000 as described above, as shown in FIG. 32, the inlet Pa of the vacuum bag P is opened.

As such, when the opening Pa of the vacuum bag P is opened, the automatic opening / closing valve 2084 is blocked and the vacuum pressure is released from the bag opening part 2000. Separated from P), the width adjusting means 2040 widens the arms 2020a and 2020b so as not to be caught in the vacuum bag P.

In this state, the frame unit 600 is rotated, and the vacuum bag is moved to the contents input unit 2500 of the next process.

When moved to the contents input unit 2500, as shown in Figure 3 and 5, the food is contained in the vacuum bag (P). As described above, a technology in which the contents are dropped from the contents input part 2500 and put in the vacuum bag P according to an accurate timing is performed so that the contents are input at the time when the vacuum bag is moved to the contents input part 2500 and stopped. Therefore, it is an easy control process.

In this process, when the contents are contained from the contents input part 2500 to the vacuum bag inlet Pa, the weight of the vacuum bag P increases due to the weight of the contents, but the vacuum bag P operates as a pneumatic cylinder. The gripper 1020a is in spite of an increase in the load of the vacuum bag P because it is fixed by the grippers 1020a and 1020b operated by the cylinder means 1062a and 1062b of the bag holder 1000. It is fixed at 1020b and is movable to the next process.

The vacuum bag P is then rotated in a subsequent process to be moved to the contents sealing part 3000 side and stopped.

In addition, the vacuum bag P is moved to move the grippers 1020a and 1020b away from both sides in the process of being transferred to the next step, thereby narrowing the inlet Pa.

That is, the envelope fixing part 1000 has a wide interval between the grippers 1020a and 1020b when the motor means 1032 of the width adjusting means 1030 operates. Here, the motor means 1032 is operated to rotate by a predetermined number of revolutions in either of the reverse rotation or the forward rotation in accordance with a predetermined program of the controller 5000. Accordingly, since the grippers 1020a and 1020b are moved to be spaced apart from each other, as shown in FIG. 33, the vacuum bags P having both edges fixed to the grippers 1020a and 1020b have their inlets Pa. ) Closes naturally, narrowing the input space.

As such, when the vacuum bags P are rotated to the contents sealing part 3000 in a state where the inlet Pa is naturally closed, the contents sealing part 3000 starts to operate.

Then, the rods 3036a and 3036b of the moving cylinder means 3032a and 3032b are pulled, and the vacuum forming means 3050 operates simultaneously with this pulling operation. In this case, the upper and lower plates 3030 and 3020 are elastic means 3054a and 3054b provided in the upper and lower plates 3030 and 3020 while narrowing the gap therebetween, as shown in FIG. 35A. In between, the inlet Pa of the vacuum bag P is elastically compressed and narrowed.

In this process, since the upper elastic means 3054a mounted on the upper plate 3030 is maintained in a more protruding state than the lower surface of the upper plate 3030, before the upper and lower plates 3030 and 3020 are completely adhered to each other, The inlet Pa of the vacuum bag P is first picked up between the upper side elastic means 3054a and the lower side elastic means 3054b.

As such, the vacuum bag P is slightly picked up using the elastic force between the elastic means 3054a and 3054b, and the vacuum pressure is increased through the vacuum suction port 3058 of the vacuum forming means 3050. It extends between the lower boards 3030 and 3020, and the vacuum suction port 3058 is sucked through the elastic means 3054a attached to the upper board 3030.
