A temperature measuring device for a rotary drum used for an extrusion coating device for laminating a synthetic resin in a film form, and the like, and having the temperature Rotary drum and temperature measuring method of the measuring device. [Prior Art] As an example of such a rotary drum, in the case of a rotary cooling drum, in order to rapidly cool the resin sheet or the like by the #cooling material or the surface temperature of the product, It is necessary to constantly monitor the surface temperature of the cooling drum and control the supply of cooling water as needed. Therefore, a temperature sensor is provided on the surface of the cooling drum to perform monitoring of the measured temperature detected by the temperature sensor. However, in such a temperature measuring device, the cooling drum is a rotating body, and the connection of the wiring is difficult in the wired mode in which the temperature information from the temperature sensor is taken out by the signal line and the data is given to the display monitor. . Therefore, a wireless type temperature measuring device is proposed (for example, refer to Japanese Laid-Open Patent Publication No. SHO-62-207146). The wireless type temperature measuring device-5-(2) 1327955 is attached to the rotating shaft of the cooling drum. The loop antenna is used for transmitting, and the loop antenna is sent by the weak sensor to the measurement detected by the temperature sensor, and the receiving loop is set in the vicinity of the rotary cooling drum. Received to detect the surface temperature. [Patent Document 1] Japanese Patent Laid-Open Publication No. SHO 62-207 No. 46-46-A, and the like. It is necessary to perform the drum replacement work frequently. In the specific case, the replacement work is required in the following cases. Roller replacement is performed based on a change in a production line of a resin film or a resin sheet of a cooling material. For example, in the case where the resin type of the resin film or the like is different, the roller having the diameter or the length corresponding thereto is used based on the use of the roller to which the surface processing is applied, or the thickness of the resin film or the like, or the change in the film width. The use, etc., need to be replaced. In this case, it is necessary to frequently perform the replacement operation of the cooling drum. As in the case of the wireless type temperature measuring device described in Patent Document 1, if the antenna or the generator is mounted on the rotating shaft, it is necessary to avoid the portion and rotate the shaft. With the hoisting tool, it becomes troublesome when it is replaced, making it difficult to replace the work. Therefore, it is conceivable to provide a transmitting antenna on the side of the end surface of the cooling drum instead of the rotating shaft, and to arrange one receiving antenna near the rotating shaft of the cooling drum. However, in such a configuration, in the rotation of the cooling -6-(3) 1327955 roller, the receiving antenna enters the shadow of the rotating shaft for the transmitting antenna, and the receiving state is extremely poor. In other words, there is a problem that the temperature of the surface of the drum cannot be accurately received in the rotation of the cooling drum. Further, even in the rotary heat roller, there is a problem similar to the problem of the above-described rotary type "cooling drum". The present invention has been conceived in view of the foregoing facts, and its object is to provide • •• It is possible to accurately receive the surface temperature of the drum at the same time, and does not require special operations when the drum is replaced, and can be easily operated with a simple operation.

Information to temperature on the display • * 'Display control unit. As described above, by attaching the transmission φ unit having the transmitter having the transmitting antenna to the inner side surface of the non-metallic end cap, the weak electric wave from the transmitting antenna is not blocked by the end cover. Further, as in the conventional example of mounting a transmitter on a rotating shaft, the problem of troublesome replacement of the drum can be eliminated. In addition, by arranging the respective receiving antennas of the first and second transceivers in a position where the transmitting antenna does not simultaneously become a shadow of the rotating shaft during one rotation of the drum, the first rotation of the drum is the first one. At least one of the receiving states of the second transceiver is in a good state. Further, in the control unit, the quality of the reception state of the first and second transceivers is individually determined, and the temperature information in the good reception state is selected, and the temperature of the display is displayed based on the selected temperature information. As a result, the surface temperature can be constantly monitored since the display does not have a moment in which the rotation of the roller cannot be displayed.

In the temperature measuring device for a rotary drum, the rotary drum includes a cylindrical body that contacts the cooled sheet on the outer peripheral surface, and end caps that cover both end portions of the cylindrical body, and from the both ends At the same time, the center of the cover protrudes outwardly from the hollow rotating shaft, and the end cap of at least one of the two end covers is made of non-metal, and the inside of the cylindrical body is repeatedly filled with evaporation and condensation. The working fluid has a cooling pipe through which the cooling fluid supplied from the hollow rotating shaft flows, and indirectly cools the working fluid by flowing the cooling fluid inside the cooling pipe. With the foregoing configuration, the surface temperature of the so-called heat pipe type cooling drum can be constantly monitored correctly. The invention described in claim 5 is the temperature measuring device for a rotary drum according to the first aspect of the invention, wherein the rotary drum has a circumference that is in contact with the outer peripheral surface by the superheated sheet. a cylindrical body, and end caps covering both end portions of the cylindrical body, and a hollow rotating shaft protruding outward from a center of the both end caps, repeatedly evaporating and condensing in the cylindrical body At the same time as the working fluid, the superheated tube through which the superheated fluid supplied from the front hollow shaft is circulated is configured to indirectly heat the fluid to be supplied by the superheated fluid flowing inside the superheater. With the foregoing configuration, the surface temperature of the so-called heat pipe type heat roller can be constantly monitored correctly. In addition, the invention described in claim 6 is a type of cooling tube in which S ( gt; -10- (5) (5) 1327995 re-evaporation and condensing action fluids are provided and cooling water is circulated inside. The so-called heat pipe type cooling drum 'in addition' may be, for example, a cooling drum having a structure in which a hollow shaft is attached to a tubular drum and a cooling water is supplied from one shaft portion to be discharged from the other shaft portion. Further, a spiral cooling water pipe is provided inside to form a spiral cooling drum having a uniform temperature on the surface of the drum. The rotary heat roller may be configured to repeatedly evaporate and condense inside the cylindrical body. At the same time as the fluid, a so-called heat pipe type heat roller formed by superheated water flowing through the inside of the superheated water (or superheated steam) is additionally provided. For example, a cover having a hollow shaft is attached to the tubular drum, and the hot water is supplied from one of the shaft portions. (or superheated steam), and a heat roller having a structure that is discharged from the other shaft portion, and a spiral superheated water (or superheated steam) tube is disposed inside. A spiral heat roller or the like which is formed by uniformizing the temperature of the surface of the drum. The term "heat treated material" includes the object to be heated when the rotary heat roller is used, and when the rotary cooling drum is used, The invention of the present invention is the temperature measuring device for a rotary drum according to the first aspect of the invention, wherein the shape of the transmitting antenna is According to the above configuration, the receiving state is further improved.

The non-metallic end cap on the side is formed with a communication hole ′ for the inner space of the end cover and is provided with a switching means for closing the communication hole in the air of the # when the inner space is full of a certain temperature When the temperature is higher than the specific temperature, the above-described configuration is opened, and the switching operation of the temperature change hole in the inner space is prevented, thereby preventing the high temperature in the inner space, thereby preventing the electric temperature of the transmitter or the like existing in the internal space. In the case of malfunction, it is possible to prevent the electronic zero of the transmitter or the like from being destroyed. In more detail, for example, when the rotary drum is of the heat pipe type, the heat of the heat-treated object (the object to be cooled) is transmitted to the inside. When the air in the space is a roller, the heat of the working fluid is passed through the air in the space inside the surface of the cylindrical body. At this time, the end cap is made of non-metal, so the temperature inside the inner space rises. . Then, when the air becomes a certain temperature or higher, the communication hole is opened and communicates with the outside through the communication hole. As a result, the inside air is mixed or replaced with the outside air at a low temperature, and the inside degree is lowered. In this way, the switching operation is performed in response to the temperature change of the inner space to prevent the inside space from becoming high. The 1, 2, 3, and 4' are used as the communication holes in the inner space of the air in the communication between the one end and the outside. And connect. The result is that the sub-parts are transferred to the warm-line communication hole in the high-temperature space in the inner space between the inner space of the small inner space due to the heat of the high-temperature heat-cooling cylinder surface, and the result is ' • 11 - (8) 1327955 Prevents electronic components such as transmitters that are present in the internal space from malfunctioning due to high temperatures, and prevents electronic components such as transmitters from being damaged by heat. Therefore, the drum surface temperature can be constantly monitored correctly. The invention described in claim 8 is the rotary drum according to the seventh aspect of the invention, wherein the switch means* includes: a switch cover covering the communication hole, and a switch cover The switch cover is pushed by the first spring of the shape memory alloy in the opening direction and the second spring that pushes the switch cover in the closing direction, and the first spring of the shape of the alloy is below a certain temperature. In the case, the pulling force disappears, and when the temperature is higher than the specific temperature, a tensile force larger than the spring force of the second spring is generated; when the air in the inner space is not full of the specific temperature, the first spring loses the pulling force by the first spring. When the spring force of the second spring is pushed by the switch cover in the closing direction to close the communication hole, and the air in the inner space is at a specific temperature or higher, the first spring is resisted by the spring force of the second spring. The pulling force, the switch cover is pushed in the opening direction, so that the communication hole is turned on. According to the above configuration, the switching means for the switch communication hole can be realized by a simple structure using a spring made of a shape of an alloy. In addition, a power source such as a commercial power source or a battery is not required, and the cost can be reduced. In addition, the first spring J and the second spring J may be a coil spring, and may be a plate spring.

(Embodiment 1) Fig. 1 is a schematic block diagram showing an extrusion type bonding machine equipped with a temperature measuring device for a rotary cooling drum according to Embodiment 1. • At the time of manufacture φ of the laminated laminated paper to which the synthetic resin film is bonded to the paper, as shown in Fig. 1, the raw material paper 2 wound from the roll-shaped base paper 1 is subjected to a pair of rotary presses. The drum 3 and the rotary cooling drum 4 are wound around the winding drum 5, and the upper portion between the rotary pressing drum 3 and the rotary cooling drum 4 is disposed in the resin holder 6a. The molten synthetic resin 7 is extruded into a film-shaped extrusion die 6b, and the synthetic resin film 8 extruded from the extrusion die 6b is fed into the rotary pressing roller 3 and rotated together with the raw material paper 2 The synthetic resin film 8 is bonded to the raw material paper 2 by a rotary cooling drum 4 via a rotary cooling drum 4 to produce a laminated laminated paper 9. Fig. 2 is a view showing the overall configuration of a cooling drum provided with the temperature measuring device for the rotary cooling drum according to the first embodiment, wherein Fig. 3 is a cross-sectional view of the cooling drum, and Fig. 4 is an enlarged view of the vicinity of the end portion of the cooling drum. The sectional view, Fig. 5 is a resin end cap view of the one end side of the cooling drum viewed from the inner side, the enlarged plan view of the receiving antenna of the sixth drawing, and the supporting structure of the cooling drum of the seventh drawing. Fig. 8 is a side view showing the support structure of the cooling drum shown in Fig. 7, and Fig. 9 is a view showing the temperature measurement operation by the temperature measuring device. -11 - (11) 1327955 As shown in Fig. 2 and Fig. 3, the rotary cooling drum 4 is provided with a cylindrical body 11 in which the cooled sheet such as the raw material paper 2 shown in Fig. 1 contacts the outer peripheral surface. And a hollow rotating shaft 12 that protrudes outward from the center of the left and right ends of the cylindrical body 11. The cylindrical body 11 is provided with a sealing plate. The inner sealing plates 13, 14. While the rotating shaft 12 penetrates the center of the sealing plates 13, 14, the sealing plates 13, 14 are fixed to the rotating shaft 12' and the cylindrical body 11 is sealed by the two sealing plates 13, 14. The inside of the cylinder 11 is filled with a working fluid which is repeatedly evaporated and condensed, such as naphthalene or quinoline. Further, the rotary cooling drum 4 is attached to both end portions 12a and 12b of the rotary shaft 12, and is pivotally supported by the bearings 15 and 16 on the machine side (see Fig. 7). In the cylindrical body 11, water chamber cover plates 17, 18 are provided on the outer sides of the two sealing plates 13, 14, by means of the water chamber cover plates 17, 18 and the sealing plates 13, 14 and the inside of the cylindrical body 11. The circumferential surfaces constitute the water chambers 19, 20. Inside the cylindrical body 11, the cooling tubes 21' extending in the axial direction of the cylindrical body 11 and having both ends penetrating the two sealing plates 13 and 14 and communicating with the two water chambers 19, 20 are arranged in the circumferential direction. A plurality of cooling water supplied to the water chamber 20 of one of the two water chambers 19 and 20 through the shaft hole of the rotating shaft 12 is distributed from the water chamber 20 to the respective cooling tubes 21 After passing through the inside of each of the cooling pipes 21, it is discharged from the other water chamber 19. Further, on the outer sides of the two water chamber covers 17 and 18 of the cylindrical body 11, a circular end cover 22 covering the both ends of the cylindrical body 11 is provided, and a rotating shaft 12 is inserted through the end covers 22, 23 Each center. The end cover 22, 23 -15- (12) 1327955 in (j 5 left 23 shows the use of the but the use of the security and the function of covering the water chamber cover 17, 18 of the dressing plate Here, in the present embodiment, as will be described later, the transmitting unit 32 including the transmitting antenna 31 is attached to the inner side surface of one of the end covers 23 and 23 of the both end covers 22 and 23. Refer to Figs. 4 and 5 ). Further, by the end caps 22, 23, a space 24, 25 - is formed between the water chamber covers 17, 18 and the end covers 22, 23. This space 24, 25 is also used as a mounting to obtain the rotation of the cooling drum. • The right balance balances the weight of the space to use. However, as described above, since φ is formed on the inner side surface of the end cover 23, the structure of the transmitting antenna 31 is attached, so that the space 25 is made larger than the space 24, so that a ring is formed between the water chamber cover 18 and the end cover. Spacer ring 26. Further, as shown in Fig. 4, the end cap 23 is fixed to the water chamber cover 18 by the gap 82 by the screw 82, and is filled with the action fluid of the cylindrical body 11 to contact the circle. When the inner surface of the cylindrical body 11 is 'vaporized by heat from the cooled sheet that is in contact with the outer surface of the cylindrical body 11', it is cooled and condensed by contact with the respective cooling tubes 21 to be liquefied, and reaches the cylindrical body 1 The inner surface of 1 is in contact with it and is repeated to cool the aforementioned cooled sheet. Further, a cooling water supply roller joint 27 is connected to one end of the hollow rotating shaft 12 (see Fig. 7). Further, in the cooling drum of the above configuration, a temperature measuring device for measuring the surface temperature of the cold drum is provided. The temperature measuring device includes a temperature measuring resistor 30 (see FIG. 2) as a temperature measuring means formed of platinum embedded in the surface layer of the cylindrical body 11, and includes an inner side provided with the end cover 23. The transmitting unit of the transmitting antenna 31 (specifically, the transmitting circuit unit) or the transmitting unit 32 of the battery (refer to Figs. 4 and 5), -16- (13) 1327955, and the leg portion of the rack mounted on the cooling drum 33a 8) The receiving antennas 34 of the receiving antennas 34 and 35, Fig. 3, and the temperature control unit 38 (see Fig. 7) from the receivers 36 and 37 are configured. In the state, the electric wave used by the transmitter uses the weak electric wave that it passes. As a result, there is an advantage that a large number of peripheral devices that do not occur in the periphery are adversely affected by the electric power φ from the transmitter. The buried position of the temperature measuring resistor 30 is set at B and is at least a region where the cooling sheet contacts. This line is connected to the inner side of the end cover 23, and the 'sending unit 32 is provided as a battery 40, and it is considered that the space 25 is a high-heat battery (for example, a single manufactured by Electrocbem). Then, the battery 40 is housed in the battery case. The outer side of the 妄® is attached to the switch cover by the screw 85. 'By removing the screw 85, the cover 41 is closed from the end cover 23, and the battery can be replaced. Further, the end cap 22 is made of metal, but is made of, for example, vinyl chloride. When the end cap is generally made of a metal cover, the end cover 23 is shielded by the metal end cap, and it is not possible to obtain sufficient end cover 23 as the end cap 23 in the present embodiment. 'Although the end cover 23 is a tree, 33b (refer to the 7th and 7th (see the display of the 7th and 8th data, etc., in the present embodiment, the signal distance is lm, and the wave of the cooling drum causes a malfunction, etc. U cylinder 1 1 outer peripheral surface temperature resistance body 30 guide [element 3 2 connection. For example, the first source of the battery 40. Do, and use the heat-resistant gauge type III battery). 3, outside the end cover 23 41 (Refer to the outer side of the fourth and fifth sides, the switch end cover 2 is made of resin-made metal, but it is in the state of reception of the weak electric wave of the 5-wire 31. Therefore, it is made of resin. It is made of gold-17-(14) 1327955, but the present invention is not limited thereto, and the end caps 22 and 23 may be made of resin. Further, the end cap 23 may be made of a non-metal material, and may be made of a resin. It can also be processed from wood, thick paper, glass, tempered glass, or mineral materials (cloud In addition, the end cap 22 may be made of wood, thick paper, glass, reinforced glass, glass, or mineral material (mica), etc. • The cover 23 may be of a different material as long as it meets the non-metallic restrictions, and the end cap 22 and the end cap 23 may be made of different materials (for example, the end cap 22 is made of resin and the end cap 23 is made of glass). The antenna 31 is disposed on the inner side surface of the end cover 23. When the transmitting antenna 31 is mounted on the outer side surface of the end cover 23, it is troublesome in the replacement of the cooling roller after the destruction of the transmitting antenna 31. In addition, even if the transmitter with the transmitting antenna 31 is mounted on the inner side of the end cover 23, the transmitter is relatively lightweight, and the balance of the cooling drum is not affected. However, in the case of a small cooling drum having a small diameter, there is a slight influence. In that case, a balance weight can be provided on the side of the end cover 22. Further, in the present embodiment, based on the following Two transceivers 36 and 37 are provided. In the case where one receiving antenna is used, when the shape of the transmitting antenna 31 is small, the electric wave from the transmitting antenna 31 is shielded by the rotating shaft 12. On the other hand, when the shape of the transmitting antenna 31 is large, the area covered by the rotating shaft 12 is reduced, and the receiving state tends to be good. However, for example, 18 - (15) 1327955 When the shape of the transmitting antenna 31 is increased, the transmission energy is increased, and the use of the wireless method based on the weak electric wave is not appropriate for the configuration in which the power consumption is as small as possible. When the shape of 31 is too large, it becomes difficult to provide the inner side surface of the end cover 23. Therefore, there is a limit to the shape of the transmitting antenna 31 that is large in size and small in terms of low power consumption and a good reception state. As a result, in the method of using one receiving antenna, in the rotation of the cooling drum, there is a possibility that a good reception state cannot be obtained frequently. Therefore, in order to solve this problem, in the present embodiment, a method in which two receiving antennas 34 and 35 are used is employed. Further, in the present embodiment, the transmitting antenna 31 is a wire antenna that is shaped like a bay. By forming the shape of the antenna in an L shape as described above, a wide range of directivity characteristics can be obtained as compared with the shape of one of the rod antennas, and the reception accuracy of the receiving antenna is improved. In addition, as shown in FIG. 6, the transmitting antenna 31 has a first straight portion 31a and a second straight portion 31b that is bent at right angles with the first straight portion 31 & a first straight portion 31a and a second straight portion. ® 31b, whose full length is set to be equal. Then, the transmitting antenna 31 is attached to the end cover 23'. As shown in FIG. 5, when the end cover 23 is in a stationary state, the transmitting unit 32 (corresponding to the transmitter body) is located at the connecting end cover 23. On the straight line L1 between the center and the apex, the first straight portion 31a is perpendicular to the straight line L1, and the second straight portion 31b is arranged in parallel with the straight line L1. On the other hand, as shown in FIG. 7, the receiving antennas 34 and 35 are arranged to be perpendicular to the transmitting antenna 31 in order to improve the receiving sensitivity, and the receiving antenna 34 and the receiving antenna 35 are separately mounted on the gantry 6 The leg portions 33a and 33b of the cymbal are then placed in the arrangement state shown in Fig. 8 by the transmitting antenna 31 and the two receiving antennas 34 and 35 (16) 1327955. That is, the receiving antenna 34 35 is symmetrically arranged in the plan view of the end cover 23 for the vertical line passing through the end cap. Further, in the case where the transmitting antenna 31 rotates once in addition to the accompanying cooling, the position of the range in which the two receiving antennas 34 become the shadow of the rotating shaft 12 is -· This arrangement makes it possible to constantly improve the receiving state. Hereinafter, the 〇φ transmitting antenna 31 rotates in accordance with the rotation of the cooling drum, and the receiving antennas 34 and 35 generate a shadow region of the transmitting antenna shaft 12. Then, when the receiving antenna is placed in the area of the rotating shaft, the rotating shaft 12 is blocked and there is no receiving. Therefore, if the two receiving antennas 34 and 35 are disposed in an area where the shadow of the rotating shaft 12 is not formed, at least one of them receives a good receiving state. Therefore, as shown in the figure 9 (1), the antenna 31 is present on the line perpendicular to the axis of rotation 12, and for this position, it is determined that the receiving antennas 3 4 and 3 5 are transmitted from the apex P1. The antenna 31 to the rotating shaft 12 are connected to the terminals M1 and M2, and the receiving antenna is provided by the wiring M1, M2. When the receiving antennas 34 and 35 are both set to S1, the receiving antennas 34 and 35 simultaneously become the rotating shaft 1 and the receiving state becomes poor. In this case, at least one of the receiving antennas 34, 35, in addition to the range S1 of the receiving antennas 3, 3, obtains a good receiving state. Therefore, as will be described later, the reception levels of the antennas 34, 35 are good, and it is not preferable to select the rotation of the drum of the center of the receiving and receiving antennas 2 3 and the 3 5 at the same time. By explaining the reasons as such. As a result, the 31% of the shadows with the rotation 12 are good. The simultaneous antenna can be displayed as if the position of the J vertex p 1 is assumed. That is, the range of the outer peripheral surface is set to S 1 in this range [2 shadow, 5 if it exists in the receiving antenna, the -20- (17) 1327955 side receiving signal is judged to be good at the receiving roller. In a rotating body such as this, a good receiving state can be obtained. This point will be described in detail in the item "Temperature measurement operation by temperature device" which will be described later. Figure 10 is a block diagram showing the electrical components of the temperature measuring device. The electrical configuration of the transmitting unit 32 is obtained by amplifying the sensing amplifier 50 from the temperature sensing impedance f and by providing a microcomputer 52 for converting the analog amplifier 50 by analog amplification detection signal into a function of the A/D converter 51 of the number φ signal, 52, and a transmitter 53 having the aforementioned transmission antenna 31, And the pool 40 is configured. The temperature measuring resistor 30 is impedance tamper depending on the temperature. This change is given to the sense amplifier 50 as an analog voltage ,, which is amplified by the interest. The analog signal amplified by the sense amplifier 50 is converted into a digital detection signal to the control circuit 52 by the A/D converter 51. The control circuit 52 gives a signal to the transmitter 53 for the measurement signal. The transmitter 53 is provided with a transmission circuit including a modulation circuit for digitally detecting signals, and is superimposed and modulated on a carrier of a specific frequency, and transmitted from the transmission antenna 31. In addition, in the modulation circuit, FM modulation or FSK modulation is performed. The receivers 36 and 37 having the receiving antennas 34 and 35 are receiving circuits including a demodulating circuit. The control unit 38 is provided with: a switching circuit 55 that inputs signals from the receivers 36 and 37, switches to one of the signals, and a signal level of the received signal, and outputs a bit of the tangent of the switching circuit 55. The quasi-discrimination circuit 56 and the input detection temperature data are outputted and measured. Make 1 30 to change the electric resistance of the position detection circuit, increase the detection number and adjust the position of the detection δΑ m into the standby packet to receive the message - 21 - (18) 1327955 control circuit of the control signal 5 7. And a display 58 for monitoring the surface temperature from the control circuit data, and a DC power supply for converting the power supplied from the commercial 59 to a specific voltage. Further, the DC voltage from the power supply circuit 60 is supplied to each of the circuit elements in the supply unit 38, and is also supplied as an operation power supply in 2. * 36, 37. • In addition, when the received signal of one of the two receivers 3 and φ levels does not reach the predetermined reference shape, the position signal will be switched to the switching signal of the other receiving signal side. Road 55. Both of the two receiving signals are above the reference level, and the receivers determined in advance by the receivers 36 and 37 are formed by the receivers for the receiving signals of the receivers 37. Therefore, for example, if the receiving levels of the machines 36, 37 are above the reference level, the receiving signal of the receiver 37 is selected. The rating of the receiver 37 is based on the time when the reception signal from the receiver 36 is selected. When the reception level of the Φ 36 is less than the reference level, the number 37 from the receiver is selected. (The temperature measurement operation by the temperature measuring device) Next, the measurement operation according to the above configuration will be described with reference to FIG. Further, Fig. 9 is a view showing the position where the antenna 32 is disposed from the position where the P2 type receiving antenna 35 is disposed from the inside of the end cover 23, Fig. 9. In the rotation of the cylinder in the state of the 9th (1), for the transmitting antenna 31, the receiving antenna 57 displays the AC power supply circuit; the control to the receiving machine 37 is received: the level is Emotion, to switch the power F, select 2 in the form of two receptions, from the I level is not up to. Receiving machine's receiving information: The P3 system received by the temperature of the device is received by the cooling roller 34, 35 -22- (19) 1327955 is located in the area outside the rotating shaft 12' reception state is good. In this case, the switching circuit 55 is switched to the reception signal of the receiver 37. The reception signal from the receiver 37 is given to the control circuit 57. Then, 'with the rotation of the cooling drum, when it is in the state of the ninth (2) figure, 'for the transmitting antenna 31, the receiving antenna 34 is located outside the area of the rotating shaft 12», but, The receiving antenna 35 is in a state of being located in the shadow area S1 of the rotating shaft 12. At this time, the reception state from the receiver 37 is poor. In the bit φ quasi-discrimination circuit level discriminating circuit 56, the reception signal from the receiver 37 is determined to be less than the reference level, and is output to the switching circuit 55. Switching to the switching signal from the receiving signal side of the transceiver 36. Thereby, the reception signal from the receiver 36 is given to the control circuit 57. With the rotation of the cooling drum, when the state of the ninth (3) is reached, the receiving antennas 34 and 35 are located outside the shadow of the rotating shaft 12, and the receiving state is good. At this time, in the level determining circuit 56, the received signals of the receivers 36 and 37 are all determined to be the reference bit # or more, and the level determining circuit 56 switches the output of the switching circuit 55 to be from the receiver 37. The switching signal on the receiving signal side. Thereby, the reception signal from the receiver 37 is given to the control circuit 57. Then, with the rotation of the cooling drum, when the state of the ninth (4) is reached, the receiving antenna 35 is located outside the shadow of the rotating shaft 12, but the receiving antenna 34 is located. The state of the shadow area S1 of the rotary shaft 12. At this time, the reception state from the receiver 36 is bad. Therefore, in the level discrimination circuit 56, the reception signal is judged as not reaching the reference level, but the reception state from the receiver 37 is good. Since -23-(20) 1327955, the switching state of the switching circuit 55 is maintained, that is, the state of the receiving signal side from the shock is maintained. Thereby, the reception from the receiver 37 is given to the control circuit 57. Then, before the first antenna is rotated, the receiving antennas 34, 35 rotate the outer region of the axis 12, the receiving state is good, and the cutting 55 maintains the receiving signal side of the receiver 37, thereby receiving the signal. The volume reception signal is given to the control circuit 57. Thus, in the cooling drum, often good reception signals are given to the control circuit 57. Therefore, in the rotation of the drum, the display 58 is not temporarily unable to display and the surface temperature is constantly monitored. Further, when the control circuit 57 controls the cooling water automatically in addition to the display surface temperature, the control circuit 57 calculates the control amount based on the surface temperature measurement data that is often obtained, and adjusts the cooling water supply pump. Pu 90 Figure 7) The opening. (Embodiment 2) Fig. 1 is a view showing a rotary cooling drum according to a second embodiment, and Fig. 2 is an enlarged cross-sectional view showing the vicinity of a rotary cooling drum according to a second embodiment, and Fig. 13 is from the inner side. FIG. 14 is a cross-sectional view showing a state in which the communication hole is closed by the switch cover provided in the rotary cooling of the second embodiment, and the second embodiment of the rotary cooling drum of the second embodiment is shown in FIG. Fig. 16 is an exploded perspective view showing the connection of the rotary cooling drum of the second embodiment, and Fig. 16 is a view showing that the power is turned on by the circuit in the embodiment 37; The row of the construction is specified (the end of the cross section of the reference section is implemented, and the switch cover of the 1327955 rotary cooling drum in the vicinity of the hole of the roller 15 is opened, and the communication hole is opened. The cross-sectional view will be described with reference to the drawings. As shown in Fig. 14 and Fig. 15, it can be clearly seen that the end cover 23 is formed with a circular communication hole that allows the inner space 25 to communicate with the outside. 42. even.. through hole 4 2 is not limited to a circular shape, and may be other shapes. The communication hole 42 is closable by a switch cover 43 provided on the inner side surface 23a of the end cover 23. The switch cover 43 is made of a metal large-diameter portion 44. The diameter of the small diameter portion 45 is set to be larger than the diameter of the communication hole 42 to close the communication hole 42. Thus, when the small diameter portion 45 is made of rubber, it can be elastically resisted. The inner side surface 23a of the end cover 23 can completely close the communication hole 42. The small diameter portion 45 is made of metal and has a rubber plate attached to the end surface thereof. The first coil spring 46 made of the shape of the alloy is provided. One end of the first coil spring 46 made of the shape memory alloy is fixed to one end surface 44a of the large diameter portion 44 (the right end surface # of Fig. 14), and One end is fixed to the inner side surface 23a of the end cover 23. Further, the other end surface 44b of the large diameter portion 44 (the left end surface of Fig. 14) is formed with a support shaft 47, and the front end of the support shaft 47 is integrated. Embedding into the recess 48 formed in the water chamber cover 18, the outer circumference of the support shaft 47 is not shaped The second coil spring 49 made of alloy is used. One end of the second coil spring 49 is fixed to the surface of the water chamber cover 18, and the other end is fixed to the other end surface 44b of the large diameter portion 44. In the upper case, the first coil spring 46 made of the shape of the billion alloy spring pushes the switch cover 43 in the opening direction, and the second coil spring 49 pushes the switch cover-25-(22) 1327955 43 in the closing direction, and the shape memory alloy When the first coil spring 46 is not at a specific temperature, the pulling force disappears, and when the temperature is higher than the specific temperature, a tensile force larger than the spring force of the second coil spring 49 is generated - °. Therefore, the inner side of the end cover 23 When the air in the space 25 does not reach a certain temperature, the first coil spring 46 disappears from the pulling force 'by the spring force of the second coil spring 49, the switch cover 43 is pushed in the closing direction', so that the communication hole φ 42 is turned off. (State shown in Figure 14). Thereby, the heat of the object to be cooled is transmitted to the air in the inner space 25, and the temperature of the inner space 25 rises. When the air in the inner space 25 is at a specific temperature or higher, the spring force of the second coil spring 49 is resisted, and the opening of the switch cover 43 is pushed toward the opening direction by the tension of the first coil spring 46. Open state (state shown in Figure 16). Thereby, the inner space 25 communicates with the outside via the communication hole 42. As a result, the high temperature in the inner space 25 is mixed with the outer air which is lower than the low temperature, and the temperature is lowered. In this manner, the switching operation of the cover 4 3 is performed in response to the temperature change of the inner space 25, so that the inside of the inner space 25 can be prevented from becoming high. As a result, it is possible to prevent thermal destruction of the battery 40 in the inner space 25 or the electronic components constituting the transmitter 53 or the like. In addition, it is possible to prevent the electronic components of the transmitter or the like existing in the internal space from malfunctioning due to high temperatures. It is often possible to accurately monitor the surface temperature of the drum. Further, it is preferable that the communication hole 42 is provided in the vicinity of a transmitter or the like. In the case where the communication hole 42 is provided at a position away from the transmitter 53 or the like, it takes time to receive the influence of the temperature drop caused by the opening of the communication hole 42 -26-(23) 1327955, the transmitter, etc. The time to be exposed to high temperatures becomes long, and the risk of thermal damage of electronic components and the like constituting the transmitter becomes large. Further, in the present embodiment, it is possible to prevent the inside of the inner space 25 from being high-temperature, and the battery 40 can be used instead of the heat-resistant electric battery used in the first embodiment (for example, a single-type battery manufactured by Electrocbem Co., Ltd.), and the use is not A normal battery for heat resistant specifications. The heat-resistant specification battery is relatively expensive, and therefore, the cost can be reduced by the use of a normal battery. • The specific temperature here is, for example, the temperature in the range of 35 °C to 45 °C. In the present embodiment, the tensile force is generated at a boundary of 40 °C, and the tensile force is lost. Further, if this temperature is used, it is also effective in preventing condensation on the so-called non-contact area outside the area in contact with the object to be cooled in the cooling drum, in addition to the thermal damage prevention of the electronic parts of the battery or the air-sending machine. Hereinafter, the reason why the condensation prevention in the non-contact area of the cooling drum is effective will be described in detail. That is, the inside of the cylindrical body is filled with the working fluid which is repeatedly evaporated and condensed, and the cooling pipe through which the cooling water flows is also provided. In the so-called heat pipe type rotary cooling drum, the occurrence of condensation in the non-contact area becomes The problem is (refer to Japanese Patent Laid-Open No. 2004-1 1 654 8, paragraph 0007 to paragraph 0012). In the case where the condensation of such a non-contact area occurs in the case where a rotary cooling drum of a metal end cover is provided at both ends of the cylindrical body, the use of a metal end cap having a large heat dissipation effect becomes more complicated. Significantly, it becomes a big problem. Further, as in the present embodiment, as the end cap 23 is made of a resin, the heat radiation effect is smaller than that of the conventional metal end cap, and heat is retained in the inner space 25 to become a high temperature. In this way, for example, even if a large amount of cooling water flows into the water chamber -27-(24) 1327955 2 , the heat is transferred from the inner space 25 to the water chamber cover 18 to be relieved by the water chamber 20 The cooling water passes through the water chamber cover 18 so that the non-contact area is cooled. As a result, the occurrence of condensation can be suppressed. However, when heat is trapped in the inner space 25 and becomes high temperature, it is counterproductive from the viewpoint of prevention of thermal damage of the electronic component. Therefore, by setting the specific temperature at which the switch cover 43 is opened to 40 °C, it is possible to simultaneously achieve the effects of prevention of condensation in the non-contact area and prevention of thermal breakage of the electronic component. (Embodiment 3) FIG. 1 is a cross-sectional view showing a state in which a communication hole is closed by a switch cover provided in a rotary cooling drum according to Embodiment 3, and FIG. 8 is a communication hole according to Embodiment 2. In the vicinity of the exploded perspective view, the first embodiment shows a cross-sectional view in which the communication hole is opened by the switch cover provided in the rotary cooling drum of the third embodiment. # In the second embodiment, the shape memory alloy is used. In the third embodiment, the first coil spring 46 made of a shape memory alloy is interposed between the large diameter portion 44 and the end cover 23, and the first coil spring 46 is interposed between the large diameter portion 45 and the end cover 23. The first coil springs 46 are disposed in plural numbers around the small diameter portion 45. In such a configuration, in the same manner as in the second embodiment, the switching operation of the large-diameter portion 44 is performed in response to the temperature change of the inner space 25, thereby preventing the inside of the inner space 25 from becoming high. In addition, the switching operation of the switch cover 43 is smoothly performed in order to achieve a good balance, and the first coil springs 46 are arranged at equal intervals in the circumferential direction of the small-diameter portion 45 to be preferably -28-(25) 1327955 (others (1) In the above-described embodiment, the rotary cooling drum is used to fill the inside of the cylindrical body to refill the working fluid which is repeatedly evaporated and condensed, and the ** is provided with a cooling pipe through which the cooling water flows.
