Definitions
- the impulse heat sealer for example, when the heater wire has a standard length of 20 cm and a width of 2 mm, a large current of a low voltage such as 20V10A is required, and a heavy transformer is essential when used with a commercial power supply of 100V.
- the present inventors put a thin slit from both sides in the conventional belt-shaped heater wire, zigzag with a uniform narrow width, and electrically thin and long, so in the previous example, a high voltage low current such as 100V2A can be passed.
- a high voltage low current such as 100V2A
- the inventor considered as a countermeasure was to stick a polyimide resin film that can withstand 600 ° C. on the heater wire. As a result, the zigzag line does not extend and the disconnected end does not pop out, which is improved. However, since the full-width bag is not always sandwiched during a long usage time, the film gets burned when the number of heater wires near the ends, where the press becomes weak and the part of the heater wire that tends to float slightly becomes hot. Carbonization sometimes weakened the film.
- thermoelectric insulator On the heat generating part of the heater wire, a ceramic thin plate such as aluminum nitride having a thickness of 0.6 mm, which conducts heat well, but is electrically insulating (hereinafter referred to as heat conducting / electrical insulating material) was superimposed. Further, the periphery other than the upper surface was surrounded by a heat and electrical insulator such as glass cloth (hereinafter referred to as a thermoelectric insulator), and these were adhered and adhered to each other with an adhesive or an adhesive, and fixed on a heat radiation table.
- a heat conducting / electrical insulating material hereinafter referred to as heat conducting / electrical insulating material
- the heater wire was completely covered and the life of the cover was semipermanently extended, so there was almost no risk of electric shock. Moreover, the heat generated from the heater wire quickly appeared on the surface through the thin plate of the heat conducting / electrical insulator, and quickly cooled down when the current was turned off and the heating was stopped.

- FIG. 1 is a sectional view of an example of the heater of the present invention and a press mechanism in which it is set.
- the ribs 3 having a height of 1.7 mm provided at the edges on both sides of the upper surface of the heat radiating table 2 made of square-pipe-shaped aluminum extrusion material fixed to the opening 1 (part of the figure) of the press mechanism
- Sircon tape 4 with a thickness of 0.45mm as a heat and electrical insulator between the heat sink and the heat sink (glass cloth in silicon rubber mixed with aluminum nitride or alumina powder, manufactured by Fuji Polymer Industries)
- a zigzag iron chrome heater wire 5 having a thickness of 0.1 mm and a width of 2 mm was stacked thereon, and a thin aluminum nitride plate 6 having a thickness of 0.6 mm and a width of 2 mm was placed thereon.
- a glass cloth tape 7 having a thickness of 0.6 mm and a width of 0.8 mm is placed between both sides of the rib 3 and adjacent to the aluminum nitride 6. Then, the boundary between them and the aluminum nitride thin plate 6 including the heater wires was bonded with an adhesive. Finally, a 0.1 mm thick fluororesin tape 8 with an adhesive was pasted on the aluminum nitride thin plate 6.
- FIG. 2 is a plan view of the heater of FIG. 1 and shows a state before sticking the fluororesin tape 8 with adhesive for easy understanding.
- FIG. 3 is a plan view of the heater wire.
- the aluminum nitride thin plate 6 is an elongated quadrangle having the same size and shape as the zigzag thinned portion 9 of the heater wire 5 that generates heat, and between the ribs 3 of the heat sink on both sides in the longitudinal direction of the aluminum nitride thin plate 6.
- a glass cloth tape 7 is placed as a thermoelectric insulator having a width of 0.8 mm.
- the portion of the heater wire 5 that does not generate heat and the electrode 10 are connected to the electrode of the power circuit, although not shown in the figure, and if exposed, there is a risk of electric shock. And their boundaries were glued together with an adhesive. All the parts that could be touched by the touch from these were covered with ceramic, glass cloth, or cercon tape, and hardened with adhesive or adhesive. Since the fluororesin tape 8 is stuck on these, the prevention of electric shock is further strengthened.
- a base 12 having a soft silicon rubber 11 affixed to a thickness of 2 mm and a width of 3.4 mm was fixed to the other opening 1 of the press mechanism as in the past.
- a bag 13 made of a polyethylene film having a thickness of about 0.05 mm is inserted into the opening, pressed between the two, and the energization time is 0.8 seconds when the aluminum nitride thin plate 6 is not present. Longer time it was neatly sealed. The cooling time also became longer.
- the aluminum nitride thin plate 6 has a sealing temperature of 100 to 150 ° C., and when the polyethylene bag 14 is smaller than the width of the heater, a portion floating near the end, that is, a portion not using heat comes out. Since the heat there also moves quickly in the central direction, no portion exceeding 200 ° C. is generated instantaneously. Therefore, some commercially available silicon-based high-temperature adhesives can withstand 250 ° C. under normal use, so that they are sufficiently long-lasting and somewhat flexible so that they can follow the difference in thermal expansion of each member.
- the heater wire 5 is not accurate in dimension as shown in the plan view of FIG. 3, but a heat-generating part 9 is formed from the side of a 2 mm long strip by etching a 0.1 mm thick wide area of iron-chrome thin plate.
- the vertical slits 14 having a width of about 0.15 mm are alternately inserted, and the heater wire itself has a zigzag shape with a uniform width of about 0.4 mm. If the electrodes 10 at both ends are stretched by thermal expansion or about half the length of the electrodes 10 and fixed to the electrodes (not shown) provided on the heat radiating stand 2, the expansion and contraction of the heater wire 5 can be ignored. . This is difficult if the zigzag heater wire is thick and short, but if it is thin and long as described above, it is easy to bend in the length direction. 4 and aluminum nitride thin plate 6 can be firmly bonded to prevent movement during heating.
- the heater wire 5 By making the heater wire 5 zigzag, it becomes thinner and longer than the conventional ribbon wire of the same outer dimensions, so in the above example, the electrical resistance, which was 2 ⁇ with the ribbon wire, becomes 25 ⁇ . As a result, if a commercial power supply of 100V is passed as it is, it will be cut off instantaneously at 2 ⁇ , but if it is 25 ⁇ , a half-wave rectification will give just a good current, so there is no need to use a transformer. In this way, the slits in the heater wire can be adjusted to the target voltage, and even if the zigzag wire is somewhat non-uniform and narrow, the aluminum nitride thin plate 4 is uneven in heat within a certain range. Can be immediately averaged to provide a clean seal. Therefore, the heater of the present invention can be adapted to any purpose, and can be produced not only in a straight line but also in a shape such as a quadrangle and a circle. It can be used.
- the aluminum nitride thin plate 6 has the same shape and the same area as the heating portion 9 of the heater wire. However, if the area is larger than the heat source, the temperature will decrease, and if the surface is made narrower than the surface that receives heat with a trapezoidal cross section, the temperature will increase. As will be described later, a mountain-shaped heater auxiliary tool can also be made integrally, so that an aluminum nitride thin plate with some unevenness can be made. However, it is included in the scope of the claims as long as it has one surface in close contact with the heater wire and performs the same function as the present invention. Further, since the thickness is very good for heat conduction, it is not necessary to make it particularly thin, and about 0.6 mm is sufficient even when considering the robustness.
- rib 3 provided at the edge of the heat sink. It is intended to prevent accidents in which the hard contents of the bag inadvertently reach the mouth of the bag to be sealed and the heater is damaged when the press mechanism is closed.
- a female handle in a disinfecting bag pops out.
- the shape in which the rib 3 is provided on the heat radiating stand 2 as shown in FIG. 1 is convenient in handling the heater alone, but as shown in the sectional view of FIG. It can be said that the structure in which the edge 15 of the opening protrudes when the heater is attached to the opening 1 functions similarly. At least one rib on the side into which the bag is inserted functions. Although the height is low, it prevents accidents from the side, but it should be high enough to withstand accidents from above.
- Fig. 5 is a graph showing the heat transfer between the heater wire and the aluminum nitride sheet.
- the temperature is plotted on the vertical axis and the time is plotted on the horizontal axis.
- the sensor is a thin tape-shaped thermocouple.
- the measurement point A is between the bottom of the heater wire and the insulating circuit tape 4
- the measurement point B is a heat conducting / electrical insulator.
- the measurement was performed with the surface of a certain aluminum nitride thin plate 6 closed with a soft silicon rubber 11 with the press mechanism closed. According to this graph, it can be said that there is almost no temperature difference between point A and point B at 100 ° C. to 150 ° C. In other words, it can be said that the heat transfer in the aluminum nitride is so fast that the surface of the heater wire 5 and the aluminum nitride thin plate 6 change at the same temperature.
- the heat conducting / electrical insulator that functions in the same manner includes silicon carbide, beryllium oxide, cBN, etc., and diamond may be used if the cost is commensurate. A compound may be used. These can be used in exactly the same manner as the aluminum nitride thin plate described so far in ceramics. In terms of thermal conductivity, aluminum nitride is 150 to 250 W / m ⁇ K, but the minimum is alumina ceramics with the same conductivity as 24 W / m ⁇ K, such as iron chrome and nichrome, etc. In the claims.
- this alumina Compared to aluminum nitride, this alumina has a weaker seal even with the same calorific value, and it can be used for some reason, although the degree of thermal shock is small. However, alumina and below cannot absorb all the heat generated from the nichrome wire, and the heater wire tends to become abnormally hot.
- Thermal conductivity is also important in the case of a thermoelectric insulator that surrounds a thermal conducting / electrical insulator.
- Impulse sealers require rapid heat release and heat transfer to the aluminum pedestal when cooling begins. However, it cannot be used if its thermal conductivity is too high.
- Steatite a typical porcelain, has a thermal conductivity of 2.5 W / m ⁇ K, but when used as a thin 0.6 mm plate, it is heated through a normal strength current to escape to the heat sink at the bottom. However, sufficient heat does not come out to the surface through aluminum nitride. With a 0.9 W / m ⁇ K cercon tape, heat was generated and sealing was possible. The vicinity of this value may be slightly different depending on the amount of power applied, but it is the upper limit of usable insulators.
- the cross section of the insulator 16 made of the same material as shown in FIG. It can also be united so that it becomes a character.
- it can be made with silicon rubber cercon tape or cordierite (a kind of porcelain) with bubbles. Accordingly, in the claims, there is no time difference in processing between the insulator pasted on the bottom and the insulator surrounding up to the other surface, and includes simultaneous or integral cases. Conversely, a plurality of insulators may be stacked.
- a silicon-based insulator is filled in a gap and hardened, it can be said that the insulator itself also serves as an adhesive.
- the glass cloth tape 7 that covers the electrode 10 and the portion of the heater wire that does not generate heat in FIG. 2 is fine, but the portions that are in contact with the sides of the both ends of the aluminum nitride thin plate 6 are heat insulation, and against the electric shock of the electrode portion, In other words, it is functionally different from electrical insulation. However, because it is a glass cloth, it serves both. Steatite is electrically good, but as described above, its conductivity is too good to be used adjacent to the aluminum nitride thin plate 6. .
- the main purpose of electrical insulation is to prevent electricity from flowing, but there are local laws or standards such as pressure resistance, flame retardancy, thickness, and strength, which must be met.
- Glass tape and silicon rubber meet double insulation standards if they have a thickness of 0.6 mm, and 0.6 mm aluminum nitride thin plates and 0.45 mm cercon tapes should meet the standards as heat dissipation materials for electronic components.
- the expression thickness that the insulator is of a suitable width includes the meaning of meeting this electrical standard in addition to heat.
- the height of the surface thermoelectric insulator 7 is also important. As with the conventional sealer, if the plane is the same plane as the upper surface of the glass cloth 7 in FIG. 1 or the integrated insulator 16 in FIG. Since it can be pressed with the silicon rubber 11 of the press mechanism 1 while sandwiching a bag or film, it is finished with less wrinkles, looks beautiful, and increases the commercial value. On the other hand, if the height is low, it cannot be pinched, so wrinkles are caused at the boundary with the seal, and if the heating time is long, the edge may be cut. However, since the seal strength is not greatly affected by normal heating, the insulator 17 is low or oblique as shown in FIG.
- ⁇ Unprecedented sealing can be achieved by placing a heater auxiliary tool on the aluminum nitride thin plate 6 under the fluororesin tape to meet the purpose of the seal.
- a heater auxiliary tool for example, as shown in the cross-sectional view of FIG. 7, aluminum nitride or aluminum is used as a material, and the cross section is mountain-shaped, the height is 0.3 mm, the bottom width is 0.6 mm, and the length is the same as that of the heater. It is.
- sealing and heat cutting can be performed.
- the date can be sealed with a numerical aid, which can be called an impulse hot stamp, and there are various applications other than the date.
- a heater auxiliary tool with good heat conductivity is suitable. Therefore, ceramics such as aluminum nitride can be used, and aluminum, copper, and carbon can also be used because they are electrically insulated with aluminum nitride. If aluminum nitride is placed, it may be manufactured as a lump from the beginning. However, since the expansion coefficient is different between ceramics and metal, for a long heater, for example, if the length is 20 cm, 3.3 pieces of aluminum heater auxiliary tools with a length of 3.3 cm are pasted at intervals of 0.1 mm. It is also necessary to select materials such as a device that fills the gap when the temperature is reached, and aluminum that is mixed with a carbon coil to reduce the expansion rate. The shape can also be fixed by a physical method such as screwing or mechanical pressing so that it can be somewhat expanded and contracted by engaging with an adjacent thermoelectric insulator.
- a new heat sealer was also made by using the heater auxiliary tool to store more heat.
- a heater auxiliary tool 19 made of copper, aluminum or the like in a rectangular parallelepiped of about 1 ⁇ 2 mm is placed on the aluminum nitride thin plate 6 and the thermoelectric insulators 20 and 21 having low thermal conductivity are mounted thereon. It is used and enclosed, and the fluororesin tape 22 is fixed with adhesives at both ends, so that a space is formed in the central portion.
- the temperature of the heater auxiliary tool 19 is quickly sensed and controlled using a thin thermocouple for the temperature sensor. When the press is open, do not energize it, and when the press is closed, energize it and immediately set the heater temperature to the set height. When the press is opened, the power is cut off, so cool it down gradually.
- the bag 13 When the bag 13 is sandwiched in the opening 1 by applying pressure with a press, the bag 13 is melted by receiving heat from the heater auxiliary tool 19. At the same time, some kind of sign is issued and immediately the opening 1 is slightly opened as shown in FIG. Keep the heater away. Then, the bag 13 is sandwiched between the silicon rubber 11 and the fluororesin tape 22 and quickly cooled by air cooling. On the other hand, since the heater, that is, the aluminum nitride thin plate 6 and the heater auxiliary tool 19 are surrounded by thermoelectric insulators 20 and 21 having low thermal conductivity, the temperature does not drop so much and the opening 1 is closed in the next operation. Immediately reaches the set temperature.
- the cooling method and the speed of work are the same as those of a conventional hot plate sealer.
- a hot plate that is covered with an insulator and has fewer exposed parts has less risk of burns, less heat dissipation, and is not always energized, which is very energy saving.
- the heater auxiliary tool 19 also protects the aluminum nitride. Even if the heater auxiliary tool 19 is not provided, the same function may be achieved with the aluminum nitride thin plate 6 alone. However, if the heater auxiliary tool 19 is provided, the heat capacity is further increased, so that the sealing can be performed smoothly. However, if the heater auxiliary tool 19 is too large, replenishment of heat does not go smoothly.
- the size of the heater aid depends on the heat generation capacity of the heater wire, but it is suitable if it does not feel like waiting too much for 2-3 seconds or more from room temperature to the set temperature at the start. In the case of continuous use, since the previous heat remains in the heater, it can be used almost without waiting.
- FIG. 9 is a cross-sectional view of a sealer having the same function, but the heater auxiliary tool 19 of FIG. 8 and the heater element in which the heater wire 5 and the aluminum nitride thin plate 6 are solidified by the insulators 20 and 21 are rotated by 90 degrees. A part of 19 is made slightly longer to be exposed from the insulator, and is further made into a T shape to form a heater auxiliary tool 23. The screw 24 is one means for fixing these heater elements in physical contact.
- the function is not different from that of the sealer of FIG. 8, the load applied to the hot plate at the time of pressing is received by the insulating plate 20 and the heat sink 2, so that it does not hit the aluminum nitride thin plate 6. Therefore, it is suitable for the case where bags with different thicknesses such as gusset folds and backed tea bags are strongly pressed and sealed.
- the sealer shown in FIGS. 8 and 9 is different from the hot plate heater in that the energization is performed every time to generate heat, and the cooling is repeated. Therefore, since the energization method is the same as the impulse sealer, it can be said that it is a friend. Further, the sealer of FIG. 8 is a position obtained by reversing the sealer of FIG. 1 upside down, and the sealer of FIG. 9 is obtained by rotating the heater element by 90 degrees. However, in both cases, the relationship between adjacent materials and the way heat is transmitted remain unchanged. Therefore, “upper and lower” in the claims merely indicates the adjacent relationship of components that are directed in a certain direction, and includes cases where the components are reversed or when they are directed left and right.
- the material of the heat sink aluminum, copper, and their alloys are good for conventional impulse sealers, but if the heater is covered with an insulator with low thermal conductivity like a hot plate sealer, the effect of heat dissipation will be diminished. Is simply a base or a reinforcing plate, and may be strong iron. However, since it is certain that heat is transmitted, it is called a heat sink including these. In the heater of the present invention, the state surrounded by the heat radiating stand is the best in terms of strength and handling. However, as shown in the sectional views of the heaters in FIGS. If the good conducting / electrical insulator 6 and the heater wire 5 are hardened with an adhesive, the heater element alone can be handled alone as a replacement part, and is included in the claims.
- fluororesin tape includes a tape using a glass cloth or the like as a base material. Further, since the heater of the present invention does not become abnormally high temperature and the life of the fluororesin tape is very long, it can be applied thinly, for example, on the surface of a heat conducting / electrical insulator. Silicone rubber can also be used if thinly applied.
- the fluororesin tape and silicon rubber are collectively referred to as a release film.
- the release film of fluororesin or silicon rubber has very low thermal conductivity, that is, it is difficult to conduct heat. Since it is transmitted as thin as about 0.1 mm, the thinner the release film layer, the better, and the best is not. Laminate films with nylon, paper, non-woven fabric, etc. on the surface melt and do not adhere to the heater, so they are not necessary when used for such seals. Therefore, the case of using without a release film is also included in the claims.
- the sealer shown in FIG. 9 is suitable for a tea bag because the pressing force can be increased.
- the surface of the tea bag is paper or nylon, no release film is required.
- silicon rubber is stretched on the surface of the heater auxiliary tool 22 to a thickness of about 0.3 to 0.5 mm, for example, the difference in thickness due to the gusset fold or the backrest, that is, the difference between four and two Fill the unevenness and make a more complete seal.
- the tea bag is strong, so it is good to keep the pressure applied, but both can be done because the heater may be released if completely crushed.
- the silicon rubber in this example is not a release film, but the material is poor in heat conduction, but it can be said that it is a heater auxiliary tool thinned so that heat is easily transmitted. Furthermore, it is also effective for a thick tea bag to provide such a heater at the other end of the opening 1 of the press mechanism at the same time and heat it while pressing it up and down. Therefore, although the number of heaters is written in the claims, it includes a plurality of heaters.
- the zigzag line suitable for the present invention is not limited to the heater line of FIG. Since the slit absorbs the movement in the length direction to some extent as long as it crosses the length direction of the heater wire, the effect is the same even if it is not only vertical but also oblique or an arc as shown in FIG. 11 and 12 can also be used, but if the center line is cut, two zigzag lines in FIG. 3 can be formed, which can be considered as a combined deformation.
- the heater wire in FIG. 12 requires time and heat generation until the gap is filled with heat because the slit is too large, and the line width is not uniform, so extra heat is generated in the thin portion. In other words, the heater wire is forced. Therefore, in order to heat smoothly, the slit should be as small as possible and the line width should be uniform.
- the heater wire is a zigzag wire that is easy to bend as shown in FIG. 3, expansion and contraction can be suppressed by an adhesive, so that an extremely thin heater wire can be manufactured.
- a thermoelectric insulator such as an aluminum nitride thin plate, polyimide resin film, or glass cloth tape that is adjacent to the heater wire and is a heat conducting / electrical insulator. What is necessary is just to etch. This is because if it is thin, the electric resistance is increased and the possibility of being directly connected to a higher external power source is increased. In this case, the zigzag wire by the metal plate itself can flow a certain large current, unlike the heater wire in which oxide etc.
- the advantage of covering the heater wire with a heat conducting / electrical insulator can be applied not only to zigzag wires but also to general ribbon wires. Since ceramics such as aluminum nitride have a small expansion coefficient, a heater wire made of a metal having a small expansion coefficient, such as Invar of a nickel iron alloy, is suitable. In the case of a long sealer of 2m or 3m, the voltage applied to the heater wire is 200V or 300V, so it is safe to insulate it, or the 3m heater is composed of three 1m heater wires and the joint is not understood. , Can be used while switching at 100V. The heater wire can also be protected in the case of sealing with water or corrosive liquids.
- the metal resistance plate as the heater wire can be anything such as tungsten, which is usually used as a heater wire, in addition to iron alloys such as iron chrome and nichrome.
- the silicon rubber 11 provided in the opening of the other side of the press mechanism may be a fluororesin rubber, and other synthetic rubbers can be used when the operating temperature is low. They are called heat resistant rubbers.
- the sealer of the present invention since the sealer of the present invention is light and easy to use, it may be a sealer only on the heater side. However, although it is not in the sealer, it is necessary to put heat-resistant rubber on the work table to be pressed. Accordingly, as a press mechanism, a press mechanism including a human body, in which a person holds only a heater side by hand and seals a bag on a work table, is included in the present invention.
- the heater wires and electrodes are completely covered with heat resistant and strong aluminum nitride or glass cloth that is hard to break, so insulation can be made stronger.
- the 2m or 3m long sealer has a voltage applied to the heater wire of 200V or 300V, so minimize the risk of electric shock when using them or sealing water. Was made.
- a safe transformerless impulse sealer can be made even in countries with high commercial voltages such as 200-240V, and heavy transformers that consume large amounts of iron and copper No longer needed.
- the aluminum nitride thin plate used for the cover hardly expands or contracts, a fixing device for the release film is unnecessary. Therefore, when combined with a zigzag heater wire, as with the case of a zigzag wire alone, a heater wire extension device is unnecessary, and the structure becomes very simple.
- the conventional exposed heater wire When sealing a bag of water or acidic liquid like pickles or in an acidic atmosphere in the workplace, the conventional exposed heater wire has a drawback of corroding, but the heater of the present invention can be almost sealed. Because it can, durability has increased.
