Description

  The present invention relates to a vulcanizer system including a plurality of vulcanizers for vulcanizing and molding raw tires.

Usually, in order to vulcanize and form a raw tire, a mold (mold) in which the raw tire is loaded is heated by a heating medium, and a high-temperature and high-pressure heating medium is supplied to the internal space of the raw tire. The raw tire is heated from outside and inside. Currently, steam generated by a boiler is used as the heating medium.
In general, as shown in FIG. 7, a boiler 102 and a vulcanizer 101 outside a building 104 where a plurality of (for example, 50 to 100) vulcanizers 101 are installed are connected via a pipe 103. Thus, a vulcanizer system 100 that supplies steam generated by the boiler 102 to the vulcanizer 101 is configured. In this case, it is normal that steam is supplied from one boiler 102 to all the vulcanizers 101 in the building 104. Since this boiler 102 is large and cannot be installed near the vulcanizer 101, the total length of the piping 103 between the boiler 102 is several hundred meters.

  However, in the configuration as described above, when steam is supplied from the boiler 102 to the vulcanizer 101 via the pipe 103, a considerable part of the heat quantity of the steam is lost due to heat radiation from the pipe 103, so that a large energy loss occurs. Produce. According to the study by the present inventors, there is a trial calculation that about 1/3 of the amount of heat input from the boiler 102 is dissipated.

  Therefore, Patent Document 1 separately provides heat amount supply means for each vulcanizer that can heat a raw medium by heating the heating medium to supply heat to the bladder through the heated heating medium. Propose that. Then, the heating medium in the bladder is taken out of the vulcanizer, the circulation path for returning the taken-up heating medium into the bladder, and the heating medium circulating in the circulation path outside the vulcanizer is heated. Patent Document 1 discloses a heat quantity supply means having a temperature control device for controlling power supplied to a heater.

JP 2006-231931 A

According to Patent Document 1, although the energy loss in each vulcanizer can be reduced, there is still heat radiation from the piping connecting the boiler and the vulcanizer, so that the vulcanizer system as a whole including a plurality of vulcanizers has energy. Loss still remains large.
This invention is made | formed based on such a technical subject, and it aims at reducing an energy loss as the whole vulcanizer system provided with a some vulcanizer.

  The present inventors examined using a small boiler that can be placed closer to the vulcanizer than a large boiler. For example, as shown in FIG. 6, a vulcanizer system 10-1 to 10 that supplies steam by replacing a vulcanizer system that supplies steam by a single large boiler with small boilers 30-1 to 30-n. When the number of -n is suppressed to about several, the boilers 30-1 to 30-n can be placed near the vulcanizers 10-1 to 10-n. In this case, in order to correspond to all the vulcanizers 10-1 to 10-n, a plurality of small boilers 30-1 to 30-n are required. Here, a vulcanizer system that supplies steam from a large boiler to a vulcanizer is called a collective type, and a vulcanizer system that supplies steam from a plurality of small boilers to a vulcanizer is called a distributed type. I will decide.

  By the way, vulcanization needs to heat a green tire at about 150 to 200 ° C., and the steam supplied to the inside of the green tire requires a pressure of about 1.5 to 2.0 Mpa. However, a small boiler that can be used in a distributed vulcanizer system has a small capacity, the temperature of steam that can be supplied is about 100 ° C., and the pressure is low. Therefore, if the large boiler is simply replaced with the small boilers 30-1 to 30-n, the raw tire cannot be vulcanized. Therefore, the present inventors have provided a temperature riser and a pressure booster between the boiler and the vulcanizer, and raised the temperature to a temperature at which the steam generated by the small boiler can be vulcanized, and then increased the pressure to vulcanize. Inspired to supply the machine.

The present invention based on this idea is based on the premise that a plurality of vulcanizers are divided into groups, a number of boilers corresponding to the number of groups are provided, and a boiler for supplying steam is assigned to each group. This is a distributed vulcanizer system. The vulcanizer system of the present invention is characterized in that a heater and a booster are provided on a steam supply path that connects a vulcanizer belonging to a group and a boiler assigned to the group.
Since the distributed vulcanizer system of the present invention can shorten the pipe length from the boiler to the vulcanizer, it can remarkably reduce the heat radiation from the pipe. According to the calculation by the present inventors, when supplying steam to the same number of vulcanizers, the dispersion type vulcanizer system can reduce heat radiation by piping as much as 30% compared to the collective type.
In addition, the distributed vulcanizer system of the present invention can supply steam to vulcanizers belonging to a group by overheating and boosting with a heater and a booster even if the boiler assigned to each group is small. Therefore, the raw tire can be vulcanized without any trouble.

  In order to vulcanize the green tire, a mold in which the green tire is loaded is heated with steam, and high-temperature and high-pressure steam is supplied to the internal space of the green tire. As described above, the high temperature and high pressure steam is supplied to the internal space of the green tire in the internal space of the green tire, and the steam supplied to the mold does not need to be high pressure. Thus, the steam supplied to the mold is heated through the temperature raising device, but is supplied to the vulcanizer without passing through the pressure raising device, whereby energy loss when operating the pressure raising device can be reduced. In order to realize this, the vulcanizer system of the present invention preferably adopts the following configuration. That is, when the boiler is the upstream side, the temperature riser and the booster are arranged in order from the upstream side. Then, a mold supply path for supplying steam to the mold is branched from the steam supply path between the heater and the booster, and the mold supply path bypasses the booster and the mold is heated by the heater. Supply steam.

  Since saturated steam supplied to the vulcanizer is condensed, drain is generated in the vulcanizer. Since the drain has a temperature of 100 ° C. or higher, the waste heat generated in the vulcanizer can be recovered and used for energy saving in the vulcanizer system. Therefore, the present invention preferably includes a circulation path for collecting the drain generated in the vulcanizer and circulating it to the boiler or the steam supply path. In this case, a heating device can be provided in the circulation path, and the temperature of the drain can be raised by the heating device and then circulated through the boiler or the steam supply route.

  In order to supply steam from one boiler to a vulcanizer belonging to the group, the steam supply path is divided into a main supply path connected to the boiler and a branch branched from the main supply path toward the vulcanizer belonging to the group. It is composed of roads. Assuming that the steam supplied to the vulcanizer passes through the temperature riser and the pressure booster, the temperature riser and the pressure booster may be provided in either the main supply path or the branch path. That is, in the present invention, either one or both of the temperature riser and the booster can be provided in either one or both of the main supply path and the branch path.

  According to the distributed vulcanizer system of the present invention, the pipe length from the boiler to the vulcanizer can be shortened, so that the heat radiation from the pipe can be significantly reduced. In addition, the distributed vulcanizer system of the present invention can supply steam to the vulcanizers belonging to the group by raising the temperature and raising the pressure using a temperature riser and a pressure booster even if a small boiler is used. Tire vulcanization can be performed without hindrance.

Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.
First, a schematic configuration of the vulcanizer system 1 in the present embodiment will be described based on FIG.
In the vulcanizer system 1, a plurality of (for example, 50 to 100) vulcanizers 10-1 to 10-n are installed in the factory building 2. The vulcanizers 10-1 to 10-n are divided into n groups of groups Gr-1 to Gr-n for each of 6 to 10 units. The vulcanizer system 1 is provided with a number of boilers 30-1 to 30-n corresponding to the number n of the groups Gr-1 to Gr-n, and supplies steam to each of the groups Gr-1 to Gr-n. Boilers 30-1 to 30-n are allocated. Boilers 30-1 to 30-n allocated to the groups Gr-1 to Gr-n, and vulcanizers 10-1 to 10-n to which steam is supplied from the boilers 30-1 to 30-n, Are connected by steam supply paths 40-1 to 40-n. The steam generated in each of the boilers 30-1 to 30-n is supplied to the corresponding vulcanizers 10-1 to 10-n through the steam supply paths 40-1 to 40-n. The steam supply paths 40-1 to 40-n are configured by general piping members.

  Hereinafter, four embodiments applied to the configurations of the groups Gr-1 to Gr-n will be described in order. In the vulcanizer system 1, the vulcanizers 10-1 to 10-n, the boilers 30-1 to 30-n, and the steam supply paths 40-1 to 40-n have the same specifications, respectively. In the following description, representative symbols such as the vulcanizer 10, the boiler 30, and the steam supply path 40 may be used. Needless to say, this does not limit the vulcanizer system of the present invention.

<First Embodiment>
As shown in FIG. 1, each group Gr-1 to Gr-n includes 6 to 10 vulcanizers 10a to 10h. Steam is supplied from the boiler 30 to the vulcanizers 10a to 10h. The boiler 30 is connected to a water supply path 31 for supplying water from a supply source (not shown) to the boiler 30, and an amount of water adjusted by a valve 32 provided on the water supply path 31 is supplied to the boiler 30. The boiler 30 and the vulcanizers 10a to 10h are connected by a steam supply path 40 through which steam generated in the boiler 30 passes. A heater 35 and a booster 37 are provided on the steam supply path 40, and the heater 35 and the booster 37 raise and raise the pressure of the steam generated in the boiler 30, respectively. This temperature increase and pressure increase refers to a temperature pressure required for vulcanizing the raw tire. The same applies to the following. The steam supply path 40 is provided with a sensor 51 that detects the temperature (T1) and pressure (P1) of the steam flowing in the steam supply path 40. The controller 50 sequentially acquires the temperature (T1) and pressure (P1) detected by the sensor 51. The controller 50 controls the operation of the boiler 30, the temperature raising device 35, and the pressure raising device 37 according to the acquired temperature (T1) and pressure (P1).

<Vulcanizer 10>
The vulcanizer 10 (a to h) vulcanizes a raw tire using steam.
As shown in FIG. 5, the vulcanizer 10 includes a base 11 and a bolster plate 12 that is disposed to face the base 11 with a space therebetween. The bolster plate 12 is a column 13 built on the base 11. Is supported by
Between the base 11 and the bolster plate 12, a mold 20 that forms a cavity C filled with the raw tire T is disposed. The mold 20 is disposed between the lower mold 21, the upper mold 22 disposed above the lower mold 21, and between the lower mold 21 and the upper mold 22, and forms the ground surface of the (raw) tire T. The tread mold 23 is provided. The tread mold 23 is composed of a plurality of segments divided in the circumferential direction. The lower mold 21, the upper mold 22, and the tread mold 23 are combined to form the cavity C. The mold 20 further includes a bottom platen 24 and a bolster platen 25. The bottom platen 24 is fixed in contact with the lower surface of the lower mold 21, and the bolster platen 25 is fixed in contact with the upper surface of the upper mold 22.

  The bottom platen 24 is supported by a bottom plate 18 that can be moved up and down by a hydraulic cylinder 15 via a bottom insulator 14. The bolster platen 25 is fixed to the bolster plate 12 via the bolster insulator 16. By operating the hydraulic cylinder 15 and the central mechanism 17, the gap between the lower mold 21 and the upper mold 22 is opened to fill the cavity C with the raw tire T to be vulcanized. In the cavity C, a bladder B into which steam for molding and vulcanizing the raw tire T from the inside is disposed.

In the bladder B, although details are omitted, steam is supplied through the central mechanism 17. Steam is supplied to the central mechanism 17 of the vulcanizer 10 from first branch supply paths 42 (a to h) described later. The steam supplied into the bladder B has a temperature of about 150 to 200 ° C. and a pressure of about 1.5 to 2.0 MPa.
Steam is also supplied into the mold 20. The path in the mold 20 is formed so that steam flows in the order of the bolster platen 25, the bottom platen 24, and the tread mold 23. Steam is supplied to the bolster platen 25 from second branch supply paths 43 (a to h) described later. The steam supplied into the mold 20 has a temperature of about 150 to 200 ° C., similar to the steam supplied into the bladder B, but the pressure may be lower than about 1.5 to 2.0 MPa.
The steam supplied to the bladder B and the mold 20 is drained and discharged from the vulcanizer 10 to the discharge pipes 45 (a to h).

<Boiler 30>
The boiler 30 is a small one with small capacity. This is because the boiler 30 is placed near the vulcanizers 10a to 10h. As such a small boiler 30, for example, a boiler that can be heated to a steam temperature of about 100 ° C. with a pressure of 0.1 MPa or less and a heat transfer area of 10 m ² or less can be used, depending on the number of corresponding vulcanizers. A specific ability may be set. The steam generated by the small boiler 30 is insufficient in temperature and pressure to vulcanize the raw tire.

<Steam supply path 40>
As shown in FIG. 1, the steam supply path 40 that connects the boiler 30 and the vulcanizers 10 a to 10 h includes a main supply path 41 that is directly connected to the boiler 30, and the main supply path 41 toward the vulcanizers 10 a to 10 h. The first branch supply path 42 and the second branch supply path 43 are branched. Here, the temperature raising device 35 and the booster 37 are provided on the main supply path 41, and when the boiler 30 is located upstream of the steam supply path 40, the temperature raising device 35 and the pressure increaser 37 are sequentially arranged from the upstream side. ing.
The heating means of the temperature raising device 35 provided on the main supply path 41 is not limited, and various temperature raising means such as heating by an electric heater and heating by a flame burner can be used. The booster 37 is not limited to specific means, and various boosters such as a plunger pump, a turbine, and a compressor can be used.

The first branch supply path 42 branches from the main supply path 41 to the first branch supply paths 42 a to 42 h downstream of the booster 37. The first branch supply paths 42a to 42h are connected to the corresponding vulcanizers 10a to 10h, and supply steam to the bladder B of each vulcanizer 10a to 10h. This steam passes through the temperature riser 35 and the pressure booster 37 and is heated and pressurized.
The second branch supply path (mold supply path) 43 is branched from the main supply path 41 to the second branch supply paths 43 a to 43 h between the temperature raising device 35 and the booster 37. The second branch supply paths 43a to 43h are connected to the corresponding vulcanizers 10a to 10h, and supply steam to the molds 20 of the respective vulcanizers 10a to 10h. This steam passes through the temperature raising device 35 but bypasses the pressure raising device 37, so that only the temperature is raised.

<Controller 50>
The controller 50 holds temperature information Td and pressure information Pd of steam to be supplied into the bladder B and the mold 20 for vulcanizing the raw tire T. The temperature information Td and the pressure information Pd are appropriately set in the controller 50 according to specifications such as the size and material of the raw tire T to be vulcanized. Further, the controller 50 holds boiler capability information Cd regarding the temperature and pressure of steam generated in the boiler 30.

The controller 50 derives the operating conditions of the heater 35 and the booster 37 from the set temperature information Td and pressure information Pd, and the boiler capability information Cd, and the boiler 30 and the heater 30 based on these operating conditions. 35, the operation of the booster 37 is started.
Further, the controller 50 compares the temperature (T1) and pressure (P1) acquired from the sensor 51 with the temperature information Td and the pressure information Pd. When the acquired temperature (T1) and pressure (P1) are different from the temperature information Td and the pressure information Pd, the controller 50, under the conditions according to the differences, Furthermore, the operating conditions of the boiler 30 are controlled as necessary.
The operation of the vulcanizer system 10 described below is performed under the control of the controller 50 as described above.

<Operation of vulcanizer system 10>
Now, in order to vulcanize the raw tire T by the vulcanizer system 1, steam generated by the boiler 30 is discharged toward the main supply path 41. Since the boiler 30 is small, the temperature of the discharged steam is about 100 ° C., and the pressure in this case is about 0.1 MPa. As it is, the steam supplied to the bladder B is insufficient in temperature and pressure, so the temperature is raised to about 150 to 200 ° C. by the temperature riser 35 and further 1.5 to 2.0 MPa by the pressure booster 37. Increase the pressure.

The steam whose temperature is increased and increased by the temperature increaser 35 and the pressure increaser 37 is branched from the main supply path 41 in the first branch supply paths 42a to 42h and then supplied to the vulcanizers 10a to 10h. The steam heats and pressurizes the raw tire T from the inside through the bladder B in the bladder B provided in the vulcanizers 10a to 10h.
A part of the steam heated by the temperature raising device 35 is branched in the second branch supply paths 43a to 43h and then supplied to the vulcanizers 10a to 10h. This steam is supplied into the mold 20 provided in the vulcanizers 10a to 10h, and heats the raw tire T from the outside.
The raw tire T is heated and vulcanized by supplying steam to each of the bladder B and the mold 20 as described above. The steam is supplied toward the bladder B and the mold 20 until the vulcanization of the raw tire T is completed.

  As described above, the vulcanizer system 1 divides the plurality of vulcanizers 10-1 to 10-n installed in the factory building 2 into groups Gr-1 to Gr-n, and the boiler 30- 1 to 30-n are assigned to the groups Gr-1 to Gr-n. Therefore, since the piping length between the boilers 30-1 to 30-n and the vulcanizers 10-1 to 10-n can be shortened, the heat radiation of the piping can be reduced. In addition, the vulcanizer system 1 is provided with a temperature raising device 35 and a pressure raising device 37 in each group Gr-1 to Gr-n, and compensates for the lack of capacity of the boilers 30-1 to 30-n, so that the distributed type The vulcanizer system 10 is established. In the distributed vulcanizer system, since the number of vulcanizers 10 assigned to one boiler 30 is small, the temperature and pressure of each vulcanizer 10 can be easily controlled.

  The vulcanizer system 1 supplies the steam supplied to the molds 20 of the vulcanizers 10a to 10h via second branch supply paths 43a to 43h that bypass the booster 37. Accordingly, energy saving is realized by reducing the load on the booster 37 by the amount that the booster 37 does not process steam that does not need to be boosted.

In the above embodiment, for the convenience of branching the second branch supply paths 43a to 43h in front of the booster 37, the temperature raising device 35 and the booster 37 are arranged in this order from the upstream side. However, according to the present invention, it is not essential to branch the second branch supply paths 43a to 43h in front of the booster 37. Therefore, the booster 37 and the temperature increaser 35 are arranged in this order from the upstream side. You can also.
Moreover, although the mold 20 in the said embodiment is comprised from the lower metal mold | die 21, the upper metal mold | die 22, the tread mold | type 23, the bottom platen 24, and the bolster platen 25, the mold of this invention is not limited to this. For example, portions corresponding to the tread mold 23 may be provided in the lower mold 21 and the upper mold 22, respectively, or a mold having no platen may be used.
Furthermore, independent vulcanization of the vulcanizers 10a to 10h can be realized by providing a valve in each of the first branch supply paths 42a to 42h and the second branch supply paths 43a to 43h.

Therefore, if it supplies to the boiler 30 in addition to the water supplied from the water supply path 31, the operating capability of the boiler 30 for obtaining the steam of predetermined temperature can be made low, and it can contribute to energy saving.

In the second embodiment, a sensor 52 that detects the temperature (T2) of the drain is provided on the circulation pipe 45, and the controller 50 acquires the temperature (T2) of the drain from the sensor 52.

Based on this, the operation of the boiler 30, the temperature raising device 35, and the pressure raising device 37 is controlled. At this time, the controller 50 controls the opening degree of the valve 32 provided on the water supply path 31 and the opening degree of the valve 47 provided on the circulation pipe 45 to adjust the amount of water and drain supplied to the boiler 30. be able to.
Further, the controller 50 compares the temperature (T1), pressure (P1) acquired from the sensor 51, and the drain temperature (T2) acquired from the sensor 52 with the temperature information Td and the pressure information Pd. Based on the comparison result, the controller 50 can control the operating conditions of the temperature raising device 35 and the pressure raising device 37 and, if necessary, the boiler 30. Further, the controller 50 can adjust the discharge of the drain to the circulation pipe 45 by controlling the opening degree of the valves 46a to 46h on the discharge pipes 45a to 45h.
