After the preform 1 is placed on the preform clamping means 10, the preforms are moved in a series of process regions using the left and right moving means 20 to produce a desired container of the present invention.

In order to achieve this, a preform clamping unit 10 for holding the preform 1 and a preform moving unit 20 for moving the preform are provided. In addition, the preform heating unit, And a container forming means and a discharging means are respectively installed.

The heating means ascending and descending section 40 for raising and lowering the preform heating means 30 is located above the preform heating means 30 and the blower lifting and lowering section 60 for raising and lowering the blowing means 50 Is located above the blower means (50).

Particularly, the preform heating means 30 of the present invention comprises a container inlet heating portion 31 and a container inner heating portion 32. The container inlet (a) is heated to a higher temperature, ) Are configured to apply lower heat.

That is, since the container inlet (a) is gripped by the clamping means, the container is cooled at a high speed without being continuously maintained in a heated state. Accordingly, the container inlet (a) So that the container inlet (a) can be more easily expanded when air pressure is applied to the container by the blower.

The heating means raising and lowering portion 40 and the blower raising and lowering portion 60 are composed of a hydraulic motor or a pneumatic motor and are driven to move the preform heating means 30 and the blower means 50 up and down .

The container forming unit 70 is disposed at a lower portion of the blower means 50 and is formed of two blocks and has a half space portion for forming a container on the inside thereof. do. Since the concept of guiding the container forming part 70 to the left and right is a general description of the blower container, a further explanation will be omitted.

The blower means 50 of the present invention is mounted horizontally on the rear side portion of the operating rod 51 to feed the air supplied from the blower supplying portion 52 provided in front of the operating rod 51 to the hollow portion 53, And the front end of the hollow portion 53 of the operating rod 51 is formed as an inclined surface so as to be opened and closed by an opening and closing port 54 formed to be opposite to the opening and closing port 54, The spring 56 is connected to the guide 55 and is blocked by the guide base 55 in which the spring 56 is elastically supported in the direction opposite to the tip of the hollow portion 53. The molding material is supplied into the hollow portion 53 by the opening / When the blower is formed and demolded, the front end of the hollow portion 53 is opened by the action of pushing the opening / closing port 57 by the air pressure supplied from the blower supply portion 52, Respectively.

Hereinafter, the overall operation of the present invention will be described.

First, the preform (1) is prepared for producing the container of the present invention. The preform (1) is formed with a clamping groove.

The clamping grooves are inserted into the preform clamping means 10 so that the preforms 1 can be clamped and a series of processes can be performed.

When the clamp means 10 grasps the preform 1, the preform 1 is moved by the preform left and right moving means 20.

It is necessary to heat the preform 1 before molding the preform 1. In the present invention, the preform heating means 30 is disposed to separate the container inlet a and the container bottom b of the preform 1 And heated.

At this time, the preform heating means 30 is composed of two heating means and heats the container inlet (a) and the container bottom (b) to different temperatures.

The first heating means 31 is set to a temperature of 300 to 350 degrees to heat the vessel inlet and the second heating means 32 is set to a temperature of 250 to 300 degrees to heat the vessel interior. That is, the container inlet was set to be 50 degrees higher than the inside of the container so that the container inlet was heated to a higher temperature.

Thus, the container inlet (a) and the container bottom (b) of the preform (1) are heated to different temperatures so that they can be easily expanded in the blowing process.

The reason why the preforms 1 are heated in different rows as described above is that the clamped portions clamped by the clamping means 10 clamp the preforms 1 easily, (A) of the container is cooled more quickly, so that it can not be properly expanded in the blowing process.

In the present invention, since the container inlet (a) of the preform (1) and the container bottom (b) are heated to different temperatures, the inlet of the container and the inside of the container are expanded under the same condition during the blowing process, .

In addition, the present invention is characterized in that the heating means ascending / descending section 40 is additionally provided, the heating means 30 is lowered by a necessary time to heat the preform 1, The air pressure is supplied to the air blower, and then the air blower is raised.

After the container is formed by the container forming part 70, the container is discharged by the discharging device to finish the production of the product.

The container manufacturing method using the present invention is summarized through a flow chart as follows.

(S10) preparing a container preform having a clamping groove formed therein;

A preform clamping step (S20) of holding the clamping groove of the container preform;

(S30) moving the preform in a state of holding the upper end of the preform and moving the preform to a process region;

A preform heating step (S40) for heating the preform container to heat the container inlet and the lower inner side of the container at different temperatures, and heating the container inlet to a temperature higher than the inner bottom of the container;

A blower step (S50) of injecting air into the preform container to gradually expand the volume of the preform container and expand it to a container of a desired size;

And a container discharging step (S60) of touching the container when the container is formed in the container forming unit to remove the container suspended in the preform left and right flow means to the outside.

On the other hand, if the temperature of the preform heating means 30 is detected through the temperature sensor 30a and the control unit 100 checks the temperature of the preform heating means 30, if the temperature is out of the standard,

That is, if the temperature measurement result is out of the reference, the control unit 100 grasps and outputs a continuous alarm sound through the error signal automatic output unit 1000 to induce faulty repair.

The automatic error signal output unit 1000 includes a circuit power supply unit 1101, an error signal output unit 1102, an oscillation transformer 1103, a relay operation switching unit 1108, a relay switch 1107, A first circuit connection switch sw1, a communication terminal power switch sw2, and a power supply holding switch 1118. [

The power supply unit 1101 applies a power supply signal by itself.

The error signal output unit 1102 switches the power supply circuit when a control signal is output from the control unit.

The oscillation transformer 1103 is supplied with electricity when the power supply unit is turned on, and outputs the boosted AC current.

The switching unit 1108 for relay operation is connected to the output terminal of the oscillation transformer 1103 and is turned on by electrical supply.

The relay switch 1107 is installed at an output terminal of the relay operation switching unit 1108 and generates a magnetic force.

The first circuit connection switch (sw1) performs a function of energizing the circuit by pulling the iron wire by the relay switch (1107).

The power switch for outputting the error signal sw2 induces an error signal to be displayed by supplying power to the error signal output control unit 1140 while the iron strip is pulled by the relay switch 1107. [

The power supply switching unit 1118 is connected to the base end of the first circuit connection switch and the emitter end and the collector end are connected to the oscillation transformer 1103 and the relay operation switching unit 1108, The wire is pulled by the operation of the switch 1108 to form a closed circuit while switching is turned on, and then the operation of the relay switch 1107 is stopped. At this time, if the first circuit connecting switch sw1 and the error signal output power switch sw2 are forcibly turned off, the closed circuit is broken while the closed circuit is broken and the relay operating switch 1108 is turned on and the relay switch is turned on The first circuit connecting switch sw1 and the error signal output power switch sw2 are turned on to induce the error signal to be output continuously.

The present invention further includes a circuit element for operation 1131 and an alarm signal operation control unit power connecting piece 1132, a resilient spring 1133, a permanent magnet 1134, and a manual operation switch 1135 .

The circuit-operating piece 1131 contacts the first circuit connecting switch to turn on the power-supply holding switch portion.

The error signal output control unit power connecting conduit 1132 is designed to operate in conjunction with the circuit breaker. When the circuit breaker is turned on, the error signal output control unit is connected to the power source to induce the alarm apparatus to operate.

The elastic spring 1133 is provided between the first circuit connection switch and the circuit operation steel wire to guide the first circuit connection switch and the circuit operation wire to be kept in an off state at all times during non-operation.

The permanent magnet 1134 is installed at one end of the first circuit connection switch. When the first circuit connection switch is switched by pulling the wire for circuit operation at the time of operation of the relay switch, the circuit for operating the circuit is attached so that even if the operation of the relay switch is stopped The ON state of the switching unit for power supply maintenance is maintained.

The manual operation switch 1135 is coupled to a wire for circuit operation and a wire for connecting an error signal output control unit to the power supply. When the user operates the wire to stop the operation of the alarm signal, The operation of the error signal display unit is stopped so that the alarm signal is no longer output.

Hereinafter, the operation of the error signal automatic output unit 1000 will be described.

First, when the error signal output unit 1102 is turned on, a DC power source is connected to supply power to the oscillation transformer, and a high voltage is applied to the secondary side of the oscillation transformer.

The power source induced on the secondary side becomes a DC power source of a half wave through a rectifying diode, and this half wave DC power source becomes a more stable DC power source due to the charging and discharging action of the condenser.

This DC power source is applied to the anode terminal of the thyristor through the coil of the relay switch 1107, while the DC power source charges the capacitor through the resistor. The elevated voltage passes through the die and triggers the switching section 1108 for relay operation so that the node node and the cathode node are switched so that the operation of the relay switch is made, The circuit connection switch sw1 and the error signal output power switch sw2 are turned on to apply power to the error signal output control unit 1140 to display an error signal.

When the first circuit connection switch sw1 is activated, a base end of the power supply maintaining switch 1118 is activated, and a closed circuit is induced in the emitter end and the collector end of the power supply holding switch 1118 to supply power to the transformer Off.

That is, a voltage between the resistor 1109 and the capacitor 1110 flows through the diode 1120 to flow between the emitter terminal and the collector terminal of the power source holding switching unit 1118, and the resistance between the resistor by the bypass and the capacitor When the voltage between the resistor and the capacitor is lowered, the trigger signal to the switching unit for relay operation 1108 is stopped, so that the node end and the tail end are turned off and the current flows to the relay switch 1107 So that the power supply is continuously stopped for switching.

On the other hand, if the operator turns off the first circuit connecting switch and the error signal output power switch during the error signal output, there is no current flow in the closed circuit, and accordingly, the bias voltage flowing between the emitter end and the base end of the power- And the power supply switching unit 1118 is turned off.

The power supply switching unit 1118 is turned off to remove the bypass voltage between the resistor and the capacitor through the diode 1120 and the voltage is charged in the capacitor 1110.

The charged voltage causes a break-over phenomenon of the die 1111 and a trigger signal is output from the die to the switching section 1108 for auxiliary switch operation to move the iron piece, while maintaining the closed circuit, and at the same time, So that the error signal display unit 1150 can be continuously operated.

That is, according to the present invention, if an error factor is not cured, a warning sound is continuously output to guide the user to heal an error factor.
