Description

  The present invention is a container and system to which a function for detecting the remaining amount of raw material in siphon containers, bubblers containers and industrial sealed containers is detected by changes in vibrations in the pipes or vibration pipes in the containers, and is a component other than the pipes or vibration pipes For example, it is possible to check the remaining amount without installing foreign substances such as floating sensors and electrodes in the container, and it is possible to reduce the man-hours by visually checking the remaining amount, preventing waste of raw materials and The present invention relates to a siphon container and a bubbler container with a remaining amount reduction detector and an industrial sealed container that can prevent continuous depletion, reduce damage due to process interruption, and enable automatic operation of a plurality of containers to continuously operate the system.

  Conventionally, as a method for detecting the remaining amount of the contents of a siphon container, a method called “float” called “float” or “float switch” is used to detect the upper and lower limits of the liquid level based on the position of the float, or from the side of the container to the inside. A method of visual inspection of a glass window that can be seen through, a method of visual inspection by placing a glass tube or a transparent tube that displays the liquid level on the outside of the container vertically, or an ultrasonic oscillator provided at the top inside the container A method of deriving the liquid surface by calculating the time for which the sound wave reflects from the liquid surface of the contents, a method of deriving the liquid surface by detecting a change in capacitance or resistance value between the electrodes, and the like can be considered.

An example of a siphon container is a syrup tank of several liters to several tens of liters or more used for food, and a carbonated drink container is used as an application. A structure in which a carbon dioxide gas cylinder and a pressurized gas supply hose of a container are connected and the raw material is discharged from the raw material discharge hose by the pressure is widely spread. The material of the container is often a stainless material that is easy to manage hygiene. When the contents are food, it is often not equipped with sensors or fuel gauges to facilitate internal cleaning to prevent bacterial growth and maintain quality, and to reduce residues. Therefore, as a means of knowing the remaining amount of contents in the container, the remaining amount of contents can be estimated by calculating the accumulated amount of the contents discharged from the container or lifting and shaking while the hose is connected. Yes.

Another example is an industrial container that, unlike a syrup tank, houses various chemicals and has a wide variety of container capacities and shapes. As an example, there is a bubbler container used by being incorporated in a semiconductor manufacturing apparatus or the like. A bubbler container is structurally similar to a siphon container, but the entrance and exit are reversed. The material in the container is bubbled with a carrier gas, and the material is supplied to the apparatus together with the carrier gas. In addition, industrial containers include chemicals and hazardous materials, and there are containers that require high pressure, and a fuel gauge such as a glass tube or a peep window is not preferred. In addition, the container itself or piping may be fixed, and in such cases, the weight cannot be measured, so the remaining amount is calculated based on the flow rate of the discharged contents or the number of processes.

If the container itself is not fixed and the piping uses flexible piping or tubes, measure the remaining amount with a weigh scale or weight sensor. In this case, errors are likely to occur due to the weight and tension of the piping.

Means to solve the problem

  The siphon container (1) with the remaining amount decrease detector shown in FIG. 1 and the bubbler container (91) with the remaining amount decrease detector shown in FIG. 4 and the industrial sealed container with the remaining amount decrease detector shown in FIG. 92), in order to achieve the purpose, if a siphon container is taken as an example, a magnetic field as shown in FIG. 1 is formed at the center of a lower stabilizer (5) of a general siphon container (3) as shown in FIG. The vibration driver / sensor (21) and the circuit unit (40) are installed, and the alarm / display (39) and interface (50) are incorporated in the upper port protection / handle (6). FIG. 1 is a cross section of a siphon container (1) with a remaining amount decrease detector, and shows a case where a raw material (20) is filled in a stainless steel container (2).

One of the siphon pipes (12) is securely fixed to the raw material discharge port (18) of the upper part of the container (10), and the tip does not contact the liquid reservoir (15) of the stainless steel container (2), but is installed in the vicinity. The magnetic vibration driver / sensor (21) is installed outside the liquid reservoir (15). The siphon tube (12) functions as a vibration tube and may be a straight tube or a bent tube. Further, as shown in FIG. 9, an extension pipe of the pressurized gas pipe (13), a dummy siphon pipe incorporated in a spare port, or a spare siphon pipe can be applied as a vibration pipe. In the case where the bottom surface of the container is flat, a structure in which a magnetic vibration driver / sensor (21) is similarly installed directly under the siphon tube (12) and outside the container is adopted.

As shown in the remaining amount detector block diagram of FIG. 7, the structure of the magnetic vibration driver / sensor (21) is composed of a permanent magnet (24), a driver coil (22), a sensor coil (23), a magnetic circuit (29), It consists of a magnetic shield (30). The magnetic vibration driver and sensor (21) may be installed in the vicinity of the driver part and the sensor part divided into the magnetic circuit (29).

The pulse generated by the waveform generator (64) is adjusted by the level adjuster 2 (36 ') according to the timing generated by the oscillator (66) and the timing generator (65), and an appropriate drive amount is adjusted by the driver amplifier (62). Amplified and pulsed drive current (61) is applied to the driver coil (22). Then, a magnetic force line A (25) is generated in the magnetic circuit (29) of the magnetic vibration driver / sensor (21).

The magnetic field line A (25) passes through the magnetic circuit (29), passes through the tip of the siphon tube (12), and returns to the magnetic circuit (29) to play the siphon tube (12) and generate vibration (27) of the siphon tube. Since the raw material (20) is filled in the siphon container (1) with the remaining amount reduction detector, the siphon tube (12) is suppressed in vibration and has a short duration. When the raw material (20) decreases, the siphon tube (12) tends to vibrate at the natural frequency, and the siphon tube vibration (27) continues and attenuates gently.

Since the tip of the siphon tube (12) is magnetized by the magnetic lines of force B (26) radiated from the permanent magnet (24) of the magnetic vibration driver and sensor (21), the vibration (27) of the siphon tube is generated by the magnetic circuit (29). The line of magnetic force (26) is changed, a current is generated in the sensor coil (23), and a voltage change is generated across the resistor (31).

Since the voltage across the resistor (31) is very small, it is amplified by the sensor preamplifier (33) and the sensor amplifier (35). The limiter 1 (32) and the limiter 2 (32 ') before and after the sensor preamplifier (33) limit the induced electromotive force and high noise voltage due to the drive current (61), and the obtained signal is passed to the frequency filter (34). Let it pass. The signal is reduced by the frequency filter that passes only the natural frequency of the siphon tube (12) and low-order harmonics, and the influence of commercial frequencies of 50Hz and 60Hz and high-frequency noise is reduced, and the signal passes through the level adjuster 1 (36). Then, the determination circuit (37) makes a comparison determination of the frequency, amplitude, and duration based on the determination timing signal (67) generated by the timing generator (65) to determine the reduction of the raw material.

The determination signal is sent to the alarm / display unit (39) via the alarm signal converter (38). At the same time, the output of the determination circuit (37) is guided to the external output signal converter (44) and sent out as an external output signal (45). The external signal and the input power supply (41) are supplied from the interface (50), and the module is provided to each function of the circuit unit (40) via the power supply circuit (46) by the operation of the switch (48) or the container detection signal (49). Supply power (47). The container detection signal (49) and the output of the determination circuit (37) are sent to the interface (50) via the external output signal converter (44). The configuration of the circuit unit (40) may be simplified depending on the scale and purpose of the apparatus. The present invention is a siphon container (1) with a remaining amount decrease detector configured as described above.

A cross-sectional view of the gantry (51) and the gantry system (54) incorporating the remaining amount reduction detector (90) of the present invention is shown in FIG. 3, and a block diagram is shown in FIG. The system can be configured simply by placing the siphon container (3) on the gantry (51), and the container detection sensor (52) indicates that the siphon container (3) is mounted without operating the switch (48). The container detection signal (49) is transmitted to the circuit unit (40). The gantry system may be a wall-type structure corresponding to the magnetic vibration driver / sensor (21) on the side surface of the industrial sealed container (92) with the remaining amount decrease detector as shown in FIG.

Next, the transition of the reduction of the raw material (20) in the siphon container is shown. At first, as shown in FIG. 1, the raw material (20) is filled, but a pressurized gas (16) such as carbon dioxide gas passes through the pressurized gas supply hose (7), and the liquid level of the raw material (20) is reduced. When pressed, the raw material (20) passes through the siphon tube (12) and is discharged from the raw material discharge port (18). As shown in the detailed view of the tip of the siphon tube in FIG. 5, most of the raw material (20) is discharged from the raw material discharge hose (8) through the siphon tube (12) by the pressurized gas (16). And the raw material (20) will be in the state which remains a little. When the pressurized gas (16) is further supplied, the raw material (20) in FIG. 6 is hardly left. Eventually, the raw material runs out and only the pressurized gas (16) is discharged into the siphon tube (12).

At that time, the vibration amplitude of the siphon tube (12) becomes maximum when there is no raw material (20), and the generated vibration is the natural frequency of the siphon tube (12). Conversely, if the amount of the raw material (20) is large, the vibration (27) of the siphon tube is suppressed, in particular, the vibration duration is shortened and the vibration frequency is slightly decreased. Further, the behavior of the vibration (27) of the siphon tube varies depending on the viscosity of the raw material (20).

When the raw material (20) is reduced and a large amount of pressurized gas (16) and a small amount of raw material (20) pass through the siphon tube (12), abnormal vibration is caused. In that state, an induced electromotive force is generated in the sensor coil (23) by the vibration (27) of the siphon tube. The small induced electromotive force obtained is proportional to the strength of the siphon tube vibration (27). The magnitude and frequency of vibration differ depending on the size of the container and the length, thickness, and thickness of the siphon tube (12), and a signal having a low natural frequency of 1 Hz or less to several hundred Hz is obtained. The siphon tube (12) shown in the block diagram of FIG. 7 is selected, the frequency filter is tuned, and the vibration frequency, amplitude value, and decay time are obtained.

The obtained signal is used to determine the remaining amount of the raw material (20) in the determination circuit (37) and display an alarm and display. Then, an external output signal (45) such as an electric signal or an optical signal is generated from the interface (50). The external output signal (45) activates the valve operation button lock (42) shown in FIG. 1 via the interface (50) to prevent the valve operation button (70) from being pressed, or the alarm indicator light (43). It can be used to light up.

The siphon container (3) shown in FIG. 1 and FIG. 2 is mainly composed of main parts such as a stainless steel container (2), a siphon pipe (12), a pressurized gas pipe (13), a container upper part (10), and a container lower part (11). The material used for the siphon tube (12) and the like is often made of SUS316 or SUS304 stainless steel with good corrosion resistance, both of which are non-magnetic, and in the case of SUS304, the magnetism is strengthened by cold rolling. There is. SUS430 is easy to cold work and has magnetism. If SUS430 with magnetism is used as the material of the container, the container acts as a magnetic shield, and the siphon tube cannot act as a vibration tube. This case can be solved by using a vibration tube (96) with built-in vibration motor / magnet / magnetic sensor, which will be described later. If the permanent magnet (24) is used in the structure shown in the block diagram of FIG. 7, the tip of the siphon tube (12) can be magnetized, and the induced electromotive force is generated in the sensor coil (23) by the vibration (27) of the siphon tube. Can be obtained.

When the material of the siphon tube (12) is SUS316 or non-metal, it shows non-magnetism, so the siphon tube (12) tip portion is formed into a film or embedded with a micro magnetic material to make the siphon tube magnetized portion (63). Thereby, sufficient vibration and induced electromotive force can be obtained. Even when SUS304 having weak magnetism is used, a larger induced electromotive force can be obtained by the same process.

The bubbler container (71) shown in FIG. 4 is structurally similar to the siphon container (3) shown in FIG. 2, but the entrance and exit are reversed. For example, in the case of the siphon container (3) of FIG. 1, a pressure is applied to the raw material (20) by the pressurized gas pipe (13) connected to the pressurized gas port (17), and the raw material is discharged through the siphon pipe (12). In the case of the bubbler container (71) of FIG. 4, the raw material (20) is bubbled by the bubble (75) by the carrier gas (79) passing through the carrier gas injection pipe (72) and the raw material gas (76 ), The carrier gas injection pipe (72) tends to vibrate when the amount of the raw material (20) decreases. When the remaining amount decrease detector (90) is applied, the bubbler container (91) with the remaining amount decrease detector can be configured similarly to the siphon container (3).

In the case of a bubbler container (71) equipped with a raw material supply port (84), the raw material supply valve (85) is opened and closed by a signal of the interface (50) in order to replenish the raw material (20) in a timely manner by detecting a decrease in remaining amount It is possible to provide an automatic material supply apparatus for performing the above process.

In order to configure an automatic switching system for a plurality of siphon containers (3), bubbler containers (71) or industrial closed containers (4) as shown in FIG. 8, a plurality of gantry systems (54) are prepared. A signal generated immediately before the material (20) of one container (82) is depleted is sent from the interface (50) to the valve control circuit input (86), and the signal generated by the valve control circuit (60) is output to the valve control circuit. (68), the first valve (56) and the second valve (57) of the first container (82) are closed. Next, by opening the third valve (58) and the fourth valve (59) of the second container (83), it is possible to construct a system that enables automatic replacement of a plurality of containers.

Next, Modification 1 of the vibrating tube of this patent is a vibrating tube (93) with a built-in magnetic body that has improved vibration characteristics, and is a vibrating tube in which a magnetic body (87) is sealed at the end of the piping material. Sectional drawing of siphon container (1) with a quantity reduction | decrease detector is shown. The siphon container (3) is a siphon container in which a pressurized gas pipe (13) is extended and a magnetic body built-in vibration pipe (93) having a structure in which a magnetic body (87) is sealed inside is incorporated. A detailed view of the tube tip is shown. Similar to the siphon container of FIG. 1, pressurized gas is supplied from the pressurized gas pipe port (14) near the upper part (10) of the container. If the vibration tube with built-in magnetic body (93) shown in FIG. 9 is used, a vibration larger than that of a simple siphon tube (12) can be obtained, and a larger signal can be obtained from the sensor of the magnetic vibration driver / sensor (21). An example (101) of a combination of a magnetic substance built-in vibration tube and a magnetic vibration driver / sensor is shown.

Next, various modifications and installation examples of the vibration tube of this patent are shown in FIG. In this patent, the vibration tube modification 2 is a vibration tube with built-in vibration motor and magnetic sensor (94), which is a vibration tube in which a magnetic sensor such as a sensor coil or a Hall element and a vibration motor (88) are sealed at the tip of the piping material. is there.

FIG. 12 shows an example in which each vibrating tube is installed in an industrial sealed container (92) with a remaining amount decrease detector. FIG. 11 is a detailed sectional view of the vibration tube (94) with built-in vibration motor / magnetic sensor. The vibration motor (88) has a structure in which a weight that is biased is attached to the shaft of an ultra-small motor. When an electric current is passed, vibration (28) of the vibration tube is generated by vibration of the weight. In this case, it is possible to obtain a large vibration with a small amount of electric power by using the driver portion of the magnetic vibration driver / sensor (21), and a current is periodically applied to the vibration motor for a short time. When the current is cut off, the vibrating tube continues to vibrate with its own natural vibration, but the vibration is hindered depending on the amount of raw material. For a certain period of time after the current is cut off, the state of vibration, that is, the amount of raw material is inspected by the built-in sensor coil (23) or the sensor portion of the magnetic vibration driver / sensor.

Since the magnet is not built in the vibration motor / magnetic sensor built-in vibration tube (94), a magnet (24) is installed near the outside of the container to give a magnetic field to the magnetic sensor. The magnetic field is disturbed by the vibration of the vibrating tube, and an electric current is generated in the magnetic sensor. This is shown in FIG. 12 as an example (100) of a combination of a vibration motor / magnetic sensor built-in vibration tube and a magnet. The positional relationship between the tip of the vibrating tube and the magnet is sufficiently close, and may be on the bottom or side of the container as long as the required electromotive force is obtained.

The sensor coil (23) is housed inside the vibration motor / magnetic sensor built-in vibration tube (94) shown in the detailed view of FIG. 11 and the industrial sealed container perspective view of FIG. 12, and the magnet (24) is placed outside the container. The magnet (24) is vibrated by the vibration (28) of the vibrating tube, and an induced electromotive force can be obtained in the sensor coil (23).

Next, as a third modification of the vibration tube of this patent, a structure in which the vibration motor / magnet built-in vibration tube (95) and the sensor tube (97) are opposed to each other as shown in FIG. 12 can be considered. Show. A vibration motor (88) and a magnet (24) are sealed inside the vibration motor / magnet built-in vibration tube (95), and a magnetic sensor such as a sensor coil (23) is sealed inside the sensor tube (97). When the vibration motor / magnet built-in vibration tube (95) vibrates, the lines of magnetic force (26) change to generate an electromotive force in the sensor coil (23). An installation example of the combination (103) of the vibration motor / magnet built-in vibration tube and sensor tube is shown in FIG. A magnetic sensor such as a Hall effect element or a magnetoresistive element may be provided inside the sensor tube instead of the sensor coil (23).

Next, as a fourth modification of the vibration tube of this patent, a horizontal vibration tube (9) in which the vibration tube is attached horizontally or at an angle close to the horizontal as shown in FIG. In addition, since it can be installed on the side, it can be replaced with a conventional horizontal float switch. FIG. 12 shows an example (102) of a combination of a horizontal vibration tube and a magnetic vibration driver / sensor.

Next, FIG. 14 shows a vibration tube (96) with a built-in vibration motor / magnet / magnetic sensor as a fifth modification of the vibration tube of this patent. The vibration tube includes a vibration motor (88) therein, and either the sensor coil (23) or the magnet (24) is supported and accommodated by a support spring (98). This is a collection of the functions of a vibration tube and a sensor that can detect vibrations with a sensor coil.

This vibration motor / magnet / magnetic sensor built-in vibration tube (96) has a function of generating vibration with one vibration tube and a function of detecting the vibration of the internal magnet with the sensor coil (23). It can be widely applied to various containers. In addition, it is possible to detect the liquid level stepwise by installing a plurality of vibrating tubes. FIG. 15 shows a block diagram of the liquid level detector.

The configurations and combinations of the vibration motors, magnets, sensors, and magnetic driver / sensors of these modified components are within the scope of this patent. If the material of the vibration tube is a structure sealed with the same material as the siphon tube or the container, the possibility of contamination of the raw material is reduced. These vibrating tubes can be applied as a raw material remaining amount detector and a liquid level detector depending on the mounting position.

The invention's effect

  The present invention reduces waste of raw materials due to early container replacement by the operator's sense, uses containers that have been used in the past without installing foreign substances such as electrodes and float switches in the containers, and pipes in the containers By adding a slight change or adding a vibration tube and adding the remaining amount detection device of the present invention to the outside of the container, the exhaustion of the raw material is detected, attention is given to the next operation, and instructions such as prohibition of operation are given. Provide a system that enables It also prevents processing interruption due to sudden depletion of raw materials and enables stable system operation. Siphon container and bubbler container with built-in residual amount detector and industrial use that enables construction of a system that can be easily and centrally managed from the field and remotely, and enables automatic switching between multiple siphon containers, bubbler containers, and industrial sealed containers It is a sealed container.
