A rectangular fusion frame 161 for welding 150 to the upper rim of the container 110 and a rectangular shape spaced apart from each other with a predetermined space portion 165 disposed outside the fusion frame 161. Guide frame 164, the axial frame 161 and the fusion frame 161 and the guide frame 164 coupled to the lower portion of the upper plate 163 to be movable up and down, coupled to the outer peripheral portion of the axial bolt 167 A spring 168 elastically supporting between the upper plate 163, the fusion frame 161, and the guide frame 164, and a bottom surface of the upper plate 163 is installed when the fusion table 160 descends.

At this time, during the vertical reciprocating movement of the fusion splicing 160, the fusion splicing 160 is maintained in a horizontal state without being guided to the left and right through guide means not shown installed in the upper fixing 101.

Meanwhile, a servo motor may be applied to the first, second and third motors 310, 510 and 610 employed in each transfer means of the present invention.

In general, the servomotor is equipped with a variable resistance to measure the rotation angle of the motor inside, and can be rotated by a desired angle according to the duty ratio of the input pulse, so according to the command output from the control unit 104 Can track position and speed

In addition, more preferably, a general AC motor or a stepping motor may be applied as the first, second and third motors 310, 510, 610, and in this case, each motor 310 may be used. 510 and 610 may be configured by installing a separate encoder on the rotation axis.

Here, the stepping motor is called a pulse motor, step motor, etc. and may rotate in response to the input pulse power. The stepping motor also rotates by a given angle in proportion to the given pulse. However, stepping motors differ from servomotors in that they can be turned to the desired angle but have no feedback action. For example, even if the command is to turn about 30 degrees, even if only 10 degrees due to the load on the motor, etc., it is impossible to know whether it has turned 10 degrees or 30 degrees with the stepping motor alone.

Therefore, in case of using general AC motor or step motor, it is necessary to add a feedback system to measure the angle of the motor with the sensor such as encoder or hall sensor and to approach the input value.

In particular, the present invention is characterized in that the encoder is provided separately so that the motor can be rotated by a desired angle without using an expensive servo motor and step motor. That is, it is most preferable to install an encoder in a general AC motor to have a function of a servo motor.

At this time, as the structure of the encoder (311, 511, 611) is preferably fixed to the front end of the rotation axis of each motor 310, 510, 610, the rotating plate 710 in which a plurality of slits 720 are formed in the radial direction And an optical sensor 730 installed at an outer periphery of the rotating plate 710 to transmit the detected signal to the controller 104 so as to detect light passing through the slit 720 of the rotating plate 710. It can be configured to include. The slit is preferably formed to a size of 1/2000.

As such, when the encoders 311, 511 and 611 are installed on the rotation shafts of the motors 310, 510 and 610, they are automatically installed without the need for a separate complicated and expensive sensing and control device. The operation of the container sealing apparatus 100 can be precisely controlled.

On the other hand, Figures 7a to 7f sequentially shows the sealing packaging process of the container 110 by the automatic container sealing device 100 according to the present invention.

First, when the container 110 is seated on the opening 133 of the container holder 130 drawn out to the front side of the lower holder 102 as shown in Figure 7a, the container sensor detects this to the controller 104 A signal is transmitted, and the controller 104 rotates the first motor 310 provided in the first transfer means 300 in the forward direction to rotate the container pedestal 130 inside the upper holder 101 as shown in FIG. 7B. It will be transferred to a fixed position.

In this process, the first encoder 311 installed on the rotation axis of the first motor 310 measures the forward rotational speed of the first motor 310 and transmits it to the control unit 104, the control unit 104 In the present invention, the current position of the vessel holder 130 is determined based on the transmitted signal. When the rotation speed of the first motor 310 detected by the first encoder 311 reaches a set value, the controller 104 ) Will stop the first motor 310.

At this time, in the present invention, it is determined whether the vessel pedestal 130 is completely inserted into the upper holder 101 by the rotation speed of the first motor 310 detected through the first encoder 311, Unlike this, a separate pedestal sensor for detecting the position of the container pedestal 130 may be installed in the holder to transmit a signal to the controller 104.

Subsequently, when the container holder 130 is transferred to the predetermined position inside the upper holder 101, the controller 104 stops the first motor 310 and then rotates the third motor 610 as shown in FIG. 7C. By driving the fusion table 160 by a predetermined distance in the downward direction to seal the sealing film 150 to the open upper edge of the container 110 and at the same time cut into a rectangular shape with the cutter blade 162.

That is, as the rotary piece 620 is rotated in the forward direction about the rotation axis by the driving of the third motor 610, the stroke bearing 630 rotates and linearly swings, and transfers the fusion base 160 to a lower distance. In this process, the fusion frame 161 in a heated state presses the sealing film 150 on the upper surface of the container 110 for a predetermined time while the elasticity of the spring 168 is applied to the container 110. By fusion, the contents of the container are sealed and packaged. At the same time, the sealing film fused to the container 110 while the cutter blade 162 fixed to the bottom of the upper plate 163 is inserted through the space 165 between the fusion frame 161 and the guide frame 164. 150 is cut along the top edge of the container 110 in a rectangular shape.

In this case, the guide frame 164 presses the sealing film 150 by using the elasticity of the spring 168 on the upper surface of the container holder 130 when the sealing film 150 is cut by the canal 162. It is easy to cut the sealing film 150 by holding, so that the cut surface is made clean.

After the fusion and cutting of the sealing film 150 by the fusion base 160 is completed, the controller 104 drives the third motor 610 in the reverse direction again as shown in FIG. Will return to its original position.

In this case, the third encoder 611 installed on the rotation shaft of the third motor 610 measures the forward or reverse rotation speed of the third motor 610 and transmits it to the controller 104, and the controller 104. In this case, the transfer position of the fusion splicer 160 is determined based on the transmitted signal. When the forward / reverse rotation speed of the third motor 610 detected by the third encoder 611 reaches a set value, the controller 104 stops driving of the third motor 610.

Subsequently, when the return of the fusion base 160 is completed, the controller 104 drives the first motor 310 in the reverse direction as shown in FIG. 7E to open the container pedestal 130 in a state where the sealing packaging of the container 110 is completed. The automatic sealing process of the container 110 is completed through the operation of transporting the holder 102 back to the original position.

After the return of the vessel holder 130 is completed, the control unit 104 drives the second motor 510 as shown in FIG. 7F to rotate the take-up roll 152 by a predetermined number of times to seal the sealing film 150. By transferring a certain distance to the rear to prepare a new sealing film 150 for the sealing and cutting operation of the next container.

In this process, the second encoder 511 installed on the rotation shaft of the second motor 510 measures the rotational speed of the second motor 510 and transmits the rotational speed to the controller 104. The moving distance of the sealing film 150 by the take-up roll 152 is determined based on the transmitted signal. When the rotation speed of the second motor 510 detected by the second encoder 511 reaches a set value. The controller 104 stops driving of the second motor 510.

As such, the present invention employs the first, second and third motors 310, 510 and 610 provided in the first, second and third transfer means 300, 500 and 600 as a low-cost general AC motor. However, by installing an encoder on the rotation axis of the AC motor to have the function of a servo motor, precise automatic control of the device is possible by rotating the motor by a desired angle without using an expensive servo motor or step motor. Therefore, there is an advantage that can improve the product competitiveness by reducing the production cost.
