Abstract

PROBLEM TO BE SOLVED: To perform at least two functions by one switch by a method wherein one hold jump switch is prepared on a circuit to control the operation of a vacuum packaging machine to make it possible to optionally extend the length of respectively processes during the motion of a vacuum packaging, or stop the motion in the middle. SOLUTION: When a hold jump switch S2 is pressed in a vacuumization process, a vacuum valve VS2 is held under an open state by relay contacts X13 and 32 being closed, and a normally open contact S21, and even if a relay X2 is energized, the motion of a vacuum timer TM1 becomes invalid, and a deaeration process is held. In the meantime, when the hold jump switch S2 is pressed and released right away before the time of a vacuum timer TM1 is up, a normally open contact X23 is closed, and the relay X2 is self-held, and for this reason, not only the contact S21 but also a normally closed contact X24 of the relay X2 is opened as well, and the vacuum valve SV2 is turned off, and the deaeration process is forcibly completed, and the process is transferred to a sealing process.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum packaging machine for carrying out hermetic packaging by putting foods or the like in a heat-adhesive bag-shaped member and degassing and heat-sealing, and more particularly to a method for controlling the operation of the vacuum packaging machine. It concerns the device.

[0002]

2. Description of the Related Art In a so-called vacuum packaging machine, a food or the like is placed in a heat-adhesive bag-like member, and the inside of the bag-like member is degassed and decompressed and then sealed by heat sealing. Generally, the following steps are performed. That is, a bag-like member having a one-sided opening containing a packaged object such as food is placed in a decompressible chamber connected to a vacuum pump via an appropriate pipe. At that time, the opening side to be closed is
It is placed in a position where heat sealing is possible. An operation called a deaeration step, that is, an operation of operating a vacuum pump to discharge gas in the chamber is performed by closing the lid of the chamber. Next, the pressure sensor detects that the pressure in the chamber communicating with the inside of the bag-shaped member has reached a predetermined pressure, and thereafter, the opening of the bag-shaped member is performed by an operation called a sealing step, that is, a heat sealing device. An operation of closing the side is performed. Finally, the air release valve connected to the pipe is opened to return the pressure in the chamber to the atmospheric pressure so that the lid can be easily opened, and then the sealed bag-like member is taken out.

After the inside of the chamber and the bag-like member is evacuated as described above, a gas such as an inert gas is sealed in the chamber, and further in the bag-like member (gas filling step). Thereafter, various types of vacuum packaging machines having a gas filling device for heat-sealing the bag-shaped member are also known.

In the former vacuum packaging machine, in order to meet various needs of the user, the length of each step is arbitrarily extended or each step is stopped halfway during the operation of the vacuum packaging. There is known a device in which a switch circuit is connected to various devices related to the execution of each step. For example, there is a switch in which a deaeration time extension switch and a deaeration stop switch are provided to change the length of the deaeration step or to stop the deaeration step halfway.

Further, another type of vacuum packaging machine of the former type is provided with two types of switches called a hold or hold switch and a jump or jump switch.
When the hold switch is activated, even if the vacuum timer that controls the vacuum pump is activated, do not move on to the next degassing process.If the jump switch is activated, the vacuum timer is not activated. In some cases, the process moves to the next degassing step.

[0006]

However, in the conventional vacuum packaging machine, as described above, the two
This is a factor that hinders the reduction in manufacturing cost because the switches were separately employed, and the operation unit of each switch is provided on a control panel exposed outside the vacuum packaging machine. When the number of switches is large, not only does it have a negative effect on compactness, but it also tends to cause erroneous operations.

As a result, the normally closed contact X24 is opened, and the vacuum valve SV2 is opened.
Is closed, the normally open contact X21 is closed, and the seal valve SV3 is opened. When the normally open contact X31 of the energized relay X3 is closed, the normally closed timer contact TM2 is closed.

At the same time, the cooling timer TM3 is turned on by closing the normally open contact TM22. When the set time of the cooling timer TM3 has elapsed, the normally closed contact TM31 is opened, the magnet switch MS and the relay X1 are turned off, the vacuum pump VP is stopped, and the atmosphere release valve SV1 is opened. In addition, power supply to the case heater H2 installed in the vacuum pump starts.

When the lid is opened in anticipation of the time when the inside of the vacuum chamber returns to the atmospheric pressure due to the opening of the atmosphere release valve SV1, the opening / closing switch S1 is turned off and connected to the contact point NC side, and the vacuum valve SV2 is opened. Valve, relay X2, X

Is turned on or excited, the power relay X2 is demagnetized, the vacuum timer TM1 is energized via the normally closed contact X24, the vacuum pump VP is activated, and the vacuum valve SV2 is open. When the hold jump switch S2 is pressed, the normally open contact S22 is closed and the relay X2 is excited to open the normally closed contact X24, but the other normally open contact S2 of the hold jump switch is opened.
1 is also turned on, and the vacuum valve SV2 opens the relay contacts X13 and X32 and the normally open contact S, both of which are closed.
21 is held open, the time of the energized vacuum timer TM1 expires and its contact TM1
1 is closed and the relay X2 is excited, the vacuum valve SV
2 keeps the open state as long as the hold jump switch S2 is pressed. That is, the vacuum timer TM
The operation of 1 becomes invalid, and the deaeration step is held without being controlled by the vacuum timer TM1.

The restart of the vacuum pump VP is performed by opening and closing the lid at the discretion of the user. At that time, if the oil temperature is sufficiently warm, the vacuum pump can be restarted. Conversely, if the oil temperature has not risen, the case heater is energized again and the vacuum pump V
Heat P.

The present invention is not limited to the above embodiment, and various other modifications are possible. For example, in the control circuit according to the modified embodiment shown in FIG. 4, a gas filling step is inserted after the degassing step, and in each of the steps of degassing and gas filling, control by a hold / jump switch can be performed. It is configured to be able to. The basic configuration of the control circuit is substantially the same as that shown in FIG. 1 except for details, or it is considered that a person skilled in the art can easily judge from the description of the one shown in FIG. The operation will be described in detail below.

First, in the normal operation (FIG. 4), the earth leakage breaker ELB is on, the bag-like member to be heat-sealed is put in a vacuum chamber (not shown), and the lid (not shown) is closed. Then, the open / close switch S1 is turned on,
The power relay (magnet switch) MS is turned on,
The contact MS1 is closed, and the vacuum pump VP is started.
At the same time, the relay X1 is energized, the normally closed contact X11 is opened, and the air release valve SV1 is closed.
The vacuum valve SV2 is opened via the normally closed contact X41 which is closed to evacuate (a degassing step). The vacuum timer TM1 is turned on via the normally closed contact X41.

When the set time of the vacuum timer TM1 set to perform sufficient degassing expires, the contact TM11 is closed, the relay contact X61 is closed, and the on-state gas changeover switch SW shown in the figure. Valve G via the normally closed relay contact X21 and the normally closed relay contact X21
When V is opened, the gas timer TM4 is energized, and a gas filling process into a vacuum chamber (not shown), that is, a bag-like member, is started as is well known. Also, the closed timer contact T
The relay X4 is excited via M11 and its normally closed contact X
41 is opened, and the vacuum valve SV2 is closed. at the same time,
Closed timer contact TM11 and normally closed contact X6 of relay X6
The relay X5 is also excited via 1. When the gas changeover switch SW is in the off state, the normally closed contact shown is opened and the normally open contact is closed, so that the gas valve GV and the gas timer TM4 are not turned on, and the seal timer TM2 and the relays X2 and X3 are turned on. Then, the gas filling step is jumped to the next sealing step.

When the gas timer TM4 times out in the ON state of the gas changeover switch SW, the contact T
Since M41 is closed and the relay X2 is excited, the normally closed contact X21 is opened, the gas valve GV is closed, the power supply to the gas timer TM4 is stopped, and the gas filling process is completed.
Further, the contact TM41 of the gas timer is opened, but the normally open contact X22 is closed and the relay X2 is kept in the excited state. When the contact X22 of the relay X2 is closed, the relay X7 is excited via the normally closed contact X65 of the relay X6 to open the seal valve SV3.
M2 is also energized, and the relay X3 is excited via the normally closed contact TM21 to close the contact X31, whereby the seal heater H1 on the secondary side of the transformer TR is closed.
Is energized, and the bag-shaped member is heat-sealed in a normal procedure (sealing step). Also, normally open contact X of relay X7
72 is also closed.

When the time of the seal timer TM2 expires, the normally closed contact TM21 is opened, the relay X3 is demagnetized, the normally open contact X31 is opened, and the seal heater H1 is turned off (end of the sealing process). However, since the normally open contact X72 is closed, the seal valve SV3 continues to be in the open state. Further, the cooling timer T is set by closing the normally open contact TM22.
M3 is turned on. When the set time of the cooling timer TM3 elapses, the normally closed contact TM31 opens, the magnet switch MS and the relay X1 are turned off, and the vacuum pump VP
Stops, and the atmosphere release valve SV1 is opened.

When the lid is opened in anticipation of the time when the inside of the vacuum chamber returns to the atmospheric pressure by opening the atmosphere release valve SV1, the open / close switch S1 is turned off and the relays X2, X
4, X5, X7, seal timer TM2, cooling timer TM
3 and the like are turned off and return to the initial standby state.

Next, a method of controlling the above-described modified embodiment by using the hold jump switch S2 'will be described. In this modified embodiment, a hold / jump switch S2 'and a relay X are connected in parallel with the vacuum pump VP and the contact MS1 of the magnet switch.
6 are connected and the various contacts of the relay X6 open and close as described below to achieve the intended purpose. That is, in FIG. 4, the lid (not shown) is closed, the open / close switch S1 is turned on, the magnet switch MS and the power relay X1 are turned on or excited, the vacuum timer TM1 is energized via the normally closed contact X41, and the vacuum pump is turned on. VP
Is activated, and in the evacuation step of evacuation in which the vacuum valve SV2 'is open, when the hold jump switch S2' is pressed, the relay X6 is excited and the normally open contact X62 is closed, while the normally closed contact X62 is closed. X61 opens.

Therefore, the hold jump switch S
As long as 2 'is kept pressed, vacuum timer TM
When the timer contact TM11 is turned on and the timer contact TM11 is turned on and the relay X4 is energized to open its normally closed contact X41, the relay X5 is not energized and its normally closed contact X51 is closed. The valve SV2 is held in an open state via the normally open contact X62 and the normally closed contact X51 which are closed, and the deaeration step is held without being controlled by the vacuum timer TM1.

On the other hand, if the hold jump switch S2 'is depressed and released immediately before the time-out of the vacuum timer TM1, the relay X6 is excited by the depression of the switch S2, the normally open contact X63 is closed and the relay X6 is closed. X4
Is excited, the normally-open contact X42 is closed and the relay X4 is held in the excited state. Therefore, when the switch S2 'is released and the normally-open contact X62 is opened, the normally-closed contact X4 of the relay X4 is also opened. , The vacuum valve SV2 is a timer TM1
Will be turned off immediately regardless of The gas valves GV and V21 are connected via various closed contacts X42 and X61, normally-closed contacts of an on-state gas changeover switch SW, X21 and the like.
Electricity is supplied to the gas timer TM4 and the like, and the process enters a gas filling process.
Of course, if the gas changeover switch SW is in the off state, the gas filling step jumps, that is, jumps over, and shifts to the above-described sealing step.

Next, when the vacuum packaging machine is in the gas filling step (the gas valve GV and the gas timer TM4 are in the energized state), the hold jump switch S2 'is used.
When the switch S2 'is pressed, the gas timer TM4 times out and its contact TM41 closes to excite the relay X2, so that the normally closed contact X21 opens. Since the normally open contacts X66 and X71 of the relay X6 are closed, the gas timer T
The gas valve GV is kept open regardless of M4,
The gas filling step is held.

If the hold / jump switch S2 'is pressed and released immediately before the time of the gas timer TM4 expires, the normally open contact X64 is closed by the pressing of the switch S2', and the relay X2 is excited. Open contact X
When the switch S2 'is released and the normally closed contact X65 is closed, the relay X7 and the seal timer TM2 are energized, and the relay X3 is excited via the normally closed contact TM21 of the seal timer. Normally closed contact X71
Is opened (the normally closed contact X21 is closed by the excitation of the relay X2), the gas filling process is immediately interrupted, and the process shifts to the sealing process.
