Description

[0001]
BACKGROUND OF THE INVENTION
In the present invention, an unvulcanized product of a so-called V-belt having a trapezoidal cross section and covered with a cover canvas is suspended between a pair of V-pulley wheels, and the circumferential portion thereof is narrowed with a mold. The present invention relates to a press vulcanizing apparatus and a press vulcanizing method for vulcanizing and vulcanizing the entire circumference repeatedly by shifting the position a plurality of times and subsequently stretching and cooling. Specifically, in this cooling treatment process, the cooling belt in which the residual temperature difference is distributed stepwise immediately after the entire vulcanization is shortened to reduce the total cooling time of the cooling belt, thereby eliminating the productivity and scattering of cooling water droplets. It is intended to improve maintainability.
[0002]
[Prior art]
Japanese Patent Publication No. 45-34694 has been proposed and proposed as a conventional V-belt press vulcanizing apparatus. According to this, the V belt using the polyester core wire is annealed to control the elongation and contraction of the belt.
[0003]
In this belt processing apparatus, the belt processing is performed by using the annealing process alone as a dedicated process after manufacturing the belt. On the other hand, as in this example, an embodiment in which the cooling process is combined with each other at the time of press vulcanization and configured in an integrated process and processed in the same manner was also used. The previous belt processing apparatus heats the belt, stretches the belt in the longitudinal direction, subsequently cools it, and maintains the stretched state. In this cooling, a plurality of V belts are stretched between a pair of V pulley wheels, and water is showered from the pores of the cooling water pipe on the belt running at a constant speed to cool to a predetermined temperature. (See FIG. 9). Thus, a V-belt having excellent dimensional stability after removal is manufactured.
[0004]
[Problems to be solved by the invention]
However, in the conventional V-belt press vulcanizing apparatus as described above, the belt temperature immediately after vulcanization has a stepwise temperature distribution in the entire circumferential direction, and the portion immediately after vulcanization is the highest. The vulcanized part is lowest. In other words, the temperature of the belt at the start of cooling varies over the entire circumference of the belt, and the subsequent cooling time varies depending on the order of vulcanization, and the remaining temperatures are different. However, since the high temperature part and the comparatively low temperature part are conventionally cooled equally in the cooling, particularly the high temperature part is insufficiently cooled, and a total cooling time is required. As a result, the cycle time for manufacturing the belt is long and the productivity is hindered, and since the cooling water is showered, the working environment is poor due to the splashing of water droplets, and the maintenance of peripheral devices is also hindered.
[0005]
The object of the present invention is to improve the work environment by improving the above problems, shortening the belt cooling treatment time after vulcanization and improving the productivity, and simultaneously modifying the cooling means to suppress the generation of water droplets. An object of the present invention is to provide a V-belt press vulcanization apparatus and a press vulcanization method that can prevent rusting of equipment and reduce maintenance costs.
[0006]
[Means for Solving the Problems]
A press vulcanizing apparatus for a V-belt according to claim 1, which solves the above problem, a pair of V pulley wheels that are moved back and forth by a moving means between a cooling zone having a tension applying means and a running means and a vulcanizing zone, A press vulcanizing unit provided with a hot platen that sandwiches the upper and lower rows of a plurality of belts suspended between a pair of V pulley pulleys with a hot mold, a belt cooling unit provided with a booth means, and a belt for cooling running And adjusting means for constantly detecting the temperature and adjusting the belt running speed .
Thereby, since the cooling space can be isolated from the surroundings, the cold air can be effectively utilized. At the same time, splashing of water droplets can be prevented, and an exhaust system can be easily installed locally.
[0007]
According to the first aspect of the present invention, the belt temperature passing through the cooling section can be adjusted by detecting the belt temperature distribution realistically. In other words, it is possible to locally and intensively cool and adjust the high temperature part of the belt on the basis of the belt temperature, so that the vulcanized belts with different temperatures stepwise on the circumference of the belt according to the vulcanization order can be differentially adjusted for cooling. Thus, it is possible to cool to a uniform temperature easily, accurately and quickly without controlling the performance capacity of the cooling source.
[0008]
According to a second aspect of the present invention, there is provided a V-belt press vulcanization molding apparatus according to the first aspect, wherein the belt cooling section provided with the booth means includes at least fog water spray and cold air introduction.
Thereby, the fog water which touched the high temperature part vaporizes and evaporates instantly, and there is no scattering of water. At the same time, upward spraying can be easily performed without scattering, so that it can be suitably cooled from the back of the belt. Therefore, excessive cooling water can be prevented and running loss is small.
[0009]
The V-belt press vulcanization molding apparatus according to claim 3 suspends a plurality of unvulcanized V-belts between a pair of V-pulley wheels, and presses and vulcanizes the upper and lower rows of V-belts with hot molds. Then, the entire circumference is vulcanized by shifting the position a plurality of times in succession, and then the belt is stretched between a pair of V-pulley cars and cooled between the front and back of the belt simultaneously using the cooling booth while running between the V-pulley cars . The belt travels between the V pulley wheels, and the belt traveling speed is adjusted by constantly detecting the temperature of the belt that travels by cooling .
As a result, the cooling contact area can be cooled not only on the upper surface of the belt but also on the bottom surface of the trapezoidal shape, thereby providing cooling capacity.
[0010]
Further, in the V belt press vulcanization molding method according to claim 3, the belt is stretched between the pair of V pulley wheels, and the belt traveling speed is adjusted by always detecting the temperature of the belt that is cooled. . Thus, the belt cooling step together with the apparatus of claim 1 can be cooled based on the temperature of the belt. In other words, since the high-temperature portion of the belt can be locally and intensively adjusted for cooling, the cooling time can be shortened to optimally correspond to each size, and cooling to a uniform temperature can be performed with high accuracy.
[0011]

[0013]
When the above-mentioned vulcanization of the entire circumference is completed, the V belt 2 is suspended between the pair of V pulley wheels 5 and then moved laterally to the cooling zone Z1 (to the front of the press in FIG. 1). Stretched between the cars 5 at a predetermined inter-axis distance, rotated the driving pulley 5a to run the V-belt 2 between the V-pulley cars 5, cooled to 40 ° C, and measured with polyester core wire. A V-belt excellent in stability is manufactured.

When vulcanizing belts having different belt cross-sectional sizes, the V pulley wheel 5 and the upper, middle, and lower heating plates 41, 42, and 43 are replaced by one set.
[0017]
Next, the tension applying means of the V pulley wheels 5a and 5b is configured to move in the left-right direction on the integrated frame 20 shown in FIG. 1, and the distance between the shafts of the two pulley wheels 5 facing each other is increased. To do. A linear rail 23 is arranged with the operating core aligned in the left-right direction, and the longitudinal movement table 21 is guided through the linear ball bearing 22. In this drive, two ball screw bearings 24 (see FIG. 3) supported by the integral frame 20 are rotationally driven by a motor 26 using a transmission chain 25 (see FIG. 2), and fastened to a moving nut that meshes with the ball screw. The longitudinal movement table 21 is pushed and pulled.
[0018]
Each axle of the V pulley wheel 5 is connected to the beam body 34 and both ends thereof are supported by bearings so as to withstand the belt extension force. However, the bearing on the near side is the loading / unloading side of the V-belt 2 and can be released by pushing and pulling the connecting arm body 36.
[0019]
Subsequently, the travel means of the V pulley wheels 5a and 5b is such that the drive pulley wheel 5a rotates and the V belt suspended or stretched between the pulley wheels 5 travels. The drive pulley wheel 5a includes a drive motor 51. Is mounted and can be rotated (see FIG. 2).
[0020]
Further, the moving means of the V pulley wheels 5a and 5b are suspended in the above-described longitudinal direction as shown in the top view of FIG. 3, and the vulcanization zone Z2 (position during vulcanization) and the cooling zone Z1 (cooling).

The pulleys 5a and 5b of the pair of V pulley wheels 5 are respectively constructed by contrasting mechanisms in which the press vulcanizing portion 8 is located at the left and right in FIG. Both end shafts are horizontally supported by the supported beam body 34. As described above, when the belt 2 is detached from the pair of V pulley wheels 5, the support on the front side can be released by releasing the support of the connecting arm body 36. The lateral movement table 32 is mounted on a slide rail 31 fastened on the longitudinal movement table 21.
[0023]
Next, as shown in a front view in FIG. 1, the press vulcanizing unit 8 is disposed at the center between the pair of V pulley wheels 5. The upper row V1 and the lower row V2 of the belt suspended between the pulley wheels 5 are simultaneously pressed, heated under pressure, and vulcanized. This is the same as when the upper row V1 of the belt is pressed by the extension of the cylinder 45 between the middle heating platen 42 fixed between the upper and lower rows and the upper heating platen 41 located above the middle heating platen 42. The lower row V2 of the belt is pressed by the extension of the cylinder 46 between the lower heating platen 43 and the lower heating platen 43.
[0024]
When the vulcanization of a part of the unvulcanized V-belt 2 is completed, a position shift substantially corresponding to the hot platen width is rotationally driven between the V pulley wheels 5, and this is repeated in order to vulcanize the entire circumference. (See FIG. 9). The boundary of vulcanization corresponding to the joint of each vulcanization is not over-vulcanized.
[0025]
Further, with respect to the belt cooling unit 9, with the completion of vulcanization, the V belt 2 is suspended between the pair of V pulley wheels 5 and moved laterally to the cooling zone Z1 (see FIG. 3), and is stretched to a predetermined inter-axis distance. The driving pulley wheel 5a is rotationally driven by the rotative motor 51, and the vulcanized V-belt 2 is caused to travel. The following booth means 15 (see FIGS. 6 and 7) is provided for the cooling process of the traveling belt 2.

And the upper row V1 of the V belt 2 is caused to travel through the slit-like opening at the center. Further, the lower row V2 of the V belt 2 is provided in the same manner. The arrangement of the cooling means 14 in the upper and lower rows is positioned so that the portions where the press vulcanization is simultaneously performed in the upper and lower rows correspond to each other and match the positional relationship that can be cooled at the same timing.
[0029]
Subsequently, the cooling means 14 uses spray of mist-like moisture mist and cold air 64 introduced into the booth. The mist-like moisture mist is generated by supplying pressurized air and pressurized cooling water to the two-fluid spray nozzle 60. At the same time, the cold air introduced into the booth uses cold air cooled by an air heat exchanger (not shown).
[0030]
Further, as shown in FIGS. 6 and 7, in the upper row v <b> 1, a mist-like moisture mist is effectively injected also to the back surface side of the traveling belt 2. The same applies to the lower row v2. Next, a pair of belt running speed adjusting means will be described with reference to FIGS. FIG. 4 is a schematic diagram of the arrangement of the belt cooling unit and a configuration diagram of the belt traveling speed adjusting means. FIG. 5 is an adjustment flowchart of the adjusting means.
[0031]
As described above, when the vulcanization is completed, the cooling process starts. The V belt 2 suspended on the pair of V pulley wheels 5 is moved from the vulcanization zone z2 to the cooling zone z1. At the same time, between the pair of V pulley wheels 5 is set to extend to a predetermined inter-axis distance, and starts rotating.
[0032]
The belt cooling section 9 provided with the booth means 15 described above accommodates the cooling means 14 and travels while cooling the V belt 2 between the pair of V pulley wheels 5 as shown in FIG. Next, the surface temperature of the traveling V-belt 2 is further detected, and cooling is performed by freely adjusting the belt traveling speed as follows.
[0033]
As shown in FIG. 4, the adjusting means 17 includes a temperature detecting means 18 for detecting the temperature of the traveling belt 2 and a rotation control means 19 for rotationally driving the driving pulley wheel 5a.

To make adjustments. The thermometer is not necessarily limited to the non-contact type, and the contact type can be combined with a mechanism that can be freely contacted and separated. Although the cooling booth means 15 is divided and installed in the upper and lower rows, the temperature is detected in any of the upper and lower rows and travel adjustment is performed.
[0035]
As described above, it is preferable to detect the surface temperature of the V-belt 2 and perform speed control to adjust the belt traveling speed passing through the cooling booth means 15 to a predetermined speed according to the temperature difference. Cooling is possible.
[0036]
Next, the operation of the V-belt press vulcanization molding apparatus 1 will be described. The device 1 is provided with a pair of V pulley wheels 5 on the left side of FIG. 2 which is also the cooling zone z1 (see FIG. 3), and the V belt is removed after the previous cycle is completed. Is the original position, and each press hot plate satisfies a predetermined temperature.
(1) First, according to the length of the unvulcanized belt 2, the drive pulley wheel 5a and the driven pulley wheel 5b which are a pair of V pulley wheels 5 are moved to a predetermined position.
(2) A plurality of unvulcanized belts 2 are inserted into and suspended from the opposing trapezoidal grooves of the drive pulley 5a and the driven pulley 5b.
(3) Each pulley wheel 5 is moved to have an appropriate tension. Then, the pair of V pulley wheels 5 are moved laterally, and the unvulcanized belt 2 is positioned and pressed between the upper, middle, and lower heating plates of the vulcanizer, and vulcanization is started.
(4) After a predetermined vulcanization time, the press is released, the position of the subsequent unvulcanized belt 2 is shifted and vulcanized in the same manner, and this is repeated to vulcanize the entire circumference.
[0037]
(5) When vulcanization of the entire circumference is completed, the vehicle is laterally moved to the cooling zone z1 while being suspended between the pair of V pulley wheels 5 and positioned on the left side in FIG.
(6) Set the cooling booth means 15 from the retracted position to the predetermined cooling position.
(7) Switch the operation switch to the cooling mode.
(8) The temperature detector 63 attached to the entrance of the cooling booth 15 detects the temperature of the belt about to enter the booth, and controls the motor rotation to the predetermined passing speed in the cooling booth according to the temperature. Adjust.
(9) The temperature detected by the temperature sensor 63 becomes equal to or lower than the temperature determined for the entire circumference of the belt, cooling is completed, and the lamp is turned on.
(10) The cooling booth means 15 is moved backward.
(11) The V pulley wheel 5 is moved in the direction in which the belt is loosened, and the connecting arm body 36 of the bearing (see FIG. 1) on the front side of each of the pair of V pulley wheels 5 is disengaged and opened, and vulcanized. The plurality of V belts 2 having been cooled are taken out.
[0038]
Next, a V-belt press vulcanization method in the V-belt press vulcanization molding apparatus 1 will be described with reference to FIGS. First, after the vulcanization process is completed, the pair of V pulley wheels 5 is moved to the left position in FIG. 2, that is, the cooling zone z1, and the vulcanizing belt 2 is stretched between the pair of V pulley wheels 5 to rotate. Drive and start cooling. At this time, as shown in FIG. 9, the temperature distribution of the belt 2 has a stepped temperature configuration in the order of vulcanization between the vulcanization take-off temperature of 140 ° C. and the cooling completed of 40 ° C.
[0039]
Such a V-belt 2 having a step-like temperature distribution is set at a predetermined inter-axis distance and is cooled in a short time until the temperature is taken out (uniform at 40 ° C). Is made longer as the temperature is higher, that is, the traveling speed of the V-belt 2 is decreased, and the total cooling time is shortened.
[0040]
A method for detecting the belt temperature in real time and adjusting the belt running speed will be described with reference to FIG. For example, FIG. 9 shows a case where the surface temperature of the belt is measured when the press hot platen temperature is 148 ° C., the vulcanization interval is 20 minutes, the vulcanization position is shifted and the vulcanization position is shifted four times to move to the cooling zone z1. ing. The stepwise temperature distribution is 55, 70, 90, and 135 ° C. By vulcanization position in the figure, the initial vulcanization position (S1, S1 ′) is 55 ° C., the second vulcanization position (S2, S2 ′) is 70 ° C., and the third vulcanization position (S3, S3 ′). The temperature was 135 ° C. at 90 ° C. at the fourth vulcanization position (S4, S4 ′) immediately after completion of vulcanization.
[0041]
The running speed of the belt having the above stepwise temperature distribution is adjusted as follows. This will be described with reference to FIG. When the detected temperature Tb on the belt surface is T1 or more after START, the vehicle travels at a travel speed Vb of V1 m / min (a travel command is given to the driver of the rotary motor). When Tb is equal to or less than T1, the traveling speed Vb is selected from V2, V3, and V4 based on the determination values of T2, T3, and T4, and is adjusted so that the vehicle can travel freely. When Tb becomes T4 or less when the predetermined cooling temperature approaches 40 ° C, the running speed Vb is set to Vf, and it is determined that the detected temperature Tb on the belt surface is less than the predetermined temperature 40 ° C from the position for one belt revolution. And stop running.
[0042]
FIG. 5 shows the control program, which is installed and operated in the CPU in the control panel. A determination temperature value corresponding to the number of vulcanizations and a traveling speed corresponding to the temperature are obtained in advance, and the traveling speed is changed and adjusted based on the detected temperature reference as described above.
[0043]
The V-belt press vulcanization molding apparatus and the press vulcanization molding method of the present invention are not limited to those shown in FIGS. 1 to 8 and can take the following forms, for example.
(1) The booth means 15 is not necessarily limited to the belt upper row v1 and lower row v2 between the pair of V pulley wheels 5. One configuration of the belt upper and lower rows can also be adopted.
(2) The control means 19 for controlling the rotation of the pulley rotation motor 51 can employ a configuration in which a hydraulic motor is used to control the oil flow rate with a control valve so that the speed can be changed.
[0044]
【The invention's effect】
According to the press vulcanizing apparatus for the V-belt according to claim 1, since the belt cooling part can be physically isolated from the ambient atmosphere by the booth means, the cooling cold air fluid and the mist mist are locally focused. Can be used for injection. That is, a cooling source can be widely obtained. At the same time, scattering and dripping can be prevented.
[0045]
Furthermore, according to the press vulcanization apparatus for the V belt according to claim 1 and the press vulcanization method for the V belt according to claim 3 , the temperature of the belt that detects the belt temperature in real time and passes through the belt cooling section is detected. Since the running speed can be adjusted, the local high temperature part of the belt can be cooled intensively. Therefore, the belt after vulcanization, which has a stepwise temperature distribution due to the vulcanization order on the circumference at the start of cooling, is cooled to a predetermined uniform temperature in the shortest time by differential cooling that adjusts cooling for each temperature distribution. It is a product. In addition, since the speed is simply adjusted, the ability of the cooling source is not complicatedly adjusted, and a flexible belt cooling process can be performed easily, reliably and accurately. As a result, the entire circumference can be cooled to a predetermined temperature in the shortest time, the cycle of the entire process including vulcanization can be shortened, and productivity can be improved.
[0046]
According to the V-belt press vulcanization apparatus according to claim 2 and the V-belt press vulcanization method according to claim 3 , the mist water that has touched the high-temperature part by mist water cooling is instantly evaporated and evaporated. The cooling effect is demonstrated by latent heat. At the same time, it can be suitably sprayed and cooled from the back of the belt. Water droplets do not scatter, excessive cooling water that does not contribute to cooling is not supplied, and loss is reduced. Furthermore, it is effective in improving the working environment and reducing maintenance costs for peripheral equipment.
[0047]
As described above, in the invention relating to the press vulcanizing apparatus and press vulcanizing method for the V belt according to claims 1 to 3 of the present application, the temperature gap of the V belt immediately after vulcanization having a stepped temperature distribution is detected. In addition, since differential cooling can be performed in real time, it can be applied to all vulcanization belts and can be cooled in the shortest time, thereby improving productivity. At the same time, by modifying the cooling heat medium, it is possible to prevent the splashing of water droplets and the dripping of cooling water.
