Description

  The present invention relates to a roll ironer that dries and stretches laundry that has been washed and dehydrated.

  In industrial laundry machines that wash laundry such as sheets and covers used in hotels and hospitals, use roll ironers to wash and dry and stretch the dehydrated laundry. ing.

  Among these roll ironers, a calendar-type roll ironer has one or a plurality of heated heating rolls and a pressing belt wound around the heating rolls. As the heating roll, one heated by introducing high-pressure steam therein is generally used, and the pressure belt wound around the heating roll is a heat-resistant belt. Then, the driving force from the driving source is transmitted to the heating roll via a driving force transmission device such as a chain or a V-belt to rotate the heating roll, and the laundry is sandwiched between the heating roll and the pressing belt. By feeding the laundry, the laundry is pressed against the heating roll and circulates to dry and stretch the laundry.

  If the number of heating rolls is increased, even if the loading speed of the laundry is high, it is possible to finish drying while moving the laundry across a plurality of heating rolls.

  In such a conventional roll ironer, the pressing belt is fed only by the frictional force pressed by the heating roll. For this reason, if the wetness or thickness of the laundry changes, the frictional force changes, slipping and delaying the conveyance of the laundry, causing wrinkles and deteriorating the finishing quality of the laundry There is. Or the same problem occurs when the tension of the pressing belt changes due to the expansion and contraction of the pressing belt due to aging or temperature change. For example, a pressure belt used in a conventional roll ironer tends to shrink when the temperature rises due to its material characteristics. At the start of use, the temperature is low, so the tension is reduced and the pressing force is reduced.

  For this reason, in Patent Document 1, a tension roller is provided in the peripheral circuit of the pressing belt so as to be position-adjustable in the direction perpendicular to the axis, and the tension roller is urged by a pneumatic cylinder, and the pneumatic pressure supplied to the pneumatic cylinder Is controlled in relation to the temperature of the heating roll or pressing belt to adjust the tension of the pressing belt, and a speed difference is detected between the rotation speed of the heating roll and the speed of the pressing belt. When this is done, the tension of the pressing belt is applied by the pneumatic cylinder.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is an overall perspective view of a calendar type ironer according to the present invention, and FIG. 2 is a schematic side view showing the first embodiment. In the illustrated example, the roll ironer 10 includes two heating rolls 11 and 12. The heating rolls 11 and 12 are rotatably supported in the housing 13 and are heated by introducing high-pressure steam therein.

  The throwing belt 14 circulates around the front of the housing 13 by a roller that is pivotally supported by the housing 13. The upper portion of the input belt 14 is a input portion 13a, and the laundry which has been washed and dehydrated and before drying is placed on the input belt 14 and proceeds in the direction of the arrow in the figure.

  Above the closing belt 14, a closing presser belt 15 is circulated by a roller supported by the housing 13. The loaded laundry proceeds toward the heating roll 11 while being sandwiched between the loading belt 14 and the loading presser belt 15. There is a speed difference between the rotation speed of the charging belt 14 and the rotation speed of the heating roll 11, and the laundry is pressed when moving across the heating roll 11. In addition, the effect of stretching the laundry can be achieved.

  The heating roll 11 rotates clockwise in FIG. 2, and the laundry circulates in contact with the heating roll 11. The driving of the heating roll 11 will be described later.

  A plurality of compression rolls 16 are provided above the heating roll 11. A pressure from an air cylinder (not shown) acts on the compression roll 16, and the compression roll 16 is urged toward the heating roll 11, and the compression roll 16 is brought into pressure contact with the heating roll 11. It is driven to rotate by rotational force and comes into pressure contact with the laundry. Since the laundry contains a lot of water in the initial stage of drying, the laundry is pressed and stretched by pressing the laundry with the pressure roll 16.

  Further, a guide tape or a yarn introduction 17 is arranged between the pressing roll 16 and the laundry to prevent the laundry from sticking to the pressing roll 16.

  A pressing belt 18 is wound around a partial circumferential surface (about a half circumference) of the heating roll 11 at the tip of the compression roll 16 and the guide tape or yarn 17. The pressing belt 18 is composed of a plurality of heat-resistant belts arranged in parallel. The pressing belt 18 is circulated by a plurality of auxiliary rolls that are pivotally supported by the housing 13. The driving of the pressing belt 18 will be described later. The laundry is sandwiched between the heating roll 11 and the pressing belt 18 by the pressing belt 18 and circulates while being pressed against the heating roll 11 to be dried.

  When the laundry passes over the tangential portion 11a where the pressing belt 18 is separated from the heating roll 11 in the tangential direction, the laundry is peeled off from the heating roll 11 by gravity and centrifugal force, and is conveyed by the pressing belt 18. It moves on the crossing bar 19 provided in the folded portion of the head and moves to the heating roll 12.

The pressing belt 20 is composed of a plurality of heat-resistant belts arranged in parallel. The pressing belt 20 is circulated by a plurality of auxiliary rolls that are pivotally supported by the housing 13, and driving of the pressing belt 20 will be described later. The laundry is sandwiched between the heating roll 12 and the pressing belt 20 by the pressing belt 20 and circulates while being pressed against the heating roll 12, and drying further proceeds. The laundry is dried with the front and back surfaces in contact with the heated surfaces of the heating roll 11 and the heating roll 12, respectively.

  When the laundry exceeds the tangential portion 12a that is separated from the heating roll 12 in the tangential direction, the laundry is peeled off from the heating roll 12 by gravity and centrifugal force, and is conveyed by the pressing belt 20 to be dried. The stretching is completed and discharged from the discharge port 13b.

  In the example described above, the roll ironer 10 includes the two heating rolls 11 and 12. However, the invention is not limited to this, and one or three or more (usually about 1 to 6) heating rolls are provided. Can be provided. In this case, the laundry is sequentially stretched by a plurality of heating rolls and dried.

  The driving of the heating rolls 11 and 12 and the pressing belts 18 and 20 will be described with reference to FIG. A motor 21 incorporating a reduction gear as a drive source is disposed in the housing 13.

  A chain 22 spanned around a drive sprocket 21 a provided coaxially with the output shaft of the motor 21 is wound around sprockets 11 b and 12 b provided coaxially with the heating rolls 11 and 12. Here, the output shaft of the motor 21, the drive sprocket 21 a, the chain 22, and the sprockets 11 b and 12 b constitute transmission means for transmitting the driving force from the motor for the heating rolls 11 and 12. However, any configuration can be adopted as the transmission means. In the figure, when the motor 21 rotates clockwise, the heating roll 11 rotates clockwise and the heating roll 12 rotates counterclockwise.

  The heating roll 11 is further provided with a sprocket 11c coaxially with the sprocket 11b so as to be integrally rotatable. The chain 23 wound around the sprocket 11 c is wound around the small ring 24 a of the wheel shaft 24 that is pivotally supported by the housing 13. Further, the chain 25 wound around the large wheel 24b of the wheel shaft 24 is wound around the sprocket 26a. The sprocket 26 a is integrated with one auxiliary roll 26 for rotating the pressing belt 18. The sprocket 11c, the chain 23, the wheel shaft 24, the chain 25, the sprocket 26a and the auxiliary roll 26 together with the output shaft of the motor 21, the drive sprocket 21a, the chain 22 and the sprocket 11b are driven by the driving force from the motor 21 for the pressing belt 18. The transmission means for transmitting is configured. However, any configuration can be adopted as the transmission means, and the transmission means for transmitting the driving force from the motor 21 for the heating rolls 11 and 12 may be partially or entirely overlapped as described above. It does not have to be. In this way, the rotational driving force from the motor 21 is applied to the pressing belt 18 by the transmission means.

  Further, the chain 22 spanned over the drive sprocket 21 a is also wound around the small ring 28 a of the wheel shaft 28 that is pivotally supported by the housing 13. A chain 29 wound around the large wheel 28b of the wheel shaft 28 is wound around the sprocket 27a. The sprocket 27 a is integrated with one auxiliary roll 27 for rotating the pressing belt 20. The wheel shaft 28, the chain 29, the sprocket 27a, and the auxiliary roll 27 together with the output shaft of the motor 21, the drive sprocket 21a, and the chain 22 constitute transmission means for transmitting the driving force from the motor 21 for the pressing belt 20. . However, any configuration can be adopted as the transmission means, and the transmission means for transmitting the driving force from the motor 21 for the heating rolls 11 and 12 may be partially or entirely overlapped as described above. It does not have to be. In this way, a rotational driving force from the motor 21 is applied to the pressing belt 20 by the transmission means.

  Further, the chain 22 spanned over the drive sprocket 21 a is also wound around the small ring 30 a of the wheel shaft 30 pivotally supported by the housing 13. The chain 31 wound around the large wheel 30b of the wheel shaft 30 is wound around the sprocket 32a. The sprocket 32 a is integrated with one auxiliary roll 32 for rotating the charging belt 14. The wheel shaft 30, the chain 31, the sprocket 32a, and the auxiliary roll 32 together with the output shaft of the motor 21, the drive sprocket 21a, and the chain 22 constitute transmission means for transmitting the driving force from the motor 21 for the closing belt 14. . Thus, a rotational driving force from the motor 21 is applied to the closing belt 14 by the transmission means.

  The rotation speeds of the heating roll 11 and the pressing belt 18 are equal to each other in the initial state (the state where there is no laundry), and the diameters of the small wheel 24a and the large wheel 24b of the wheel shaft 24 and the diameters of the sprockets 26a, 11b, and 11c. Is decided. Similarly, the diameters of the small wheel 28a and the large wheel 28b of the wheel shaft 28 and the diameter of the sprocket 27a are equal so that the rotating speeds of the heating roll 12 and the pressing belt 20 are equal in the initial state (the state where there is no laundry). It has been decided. However, the circumferential speed of the heating roll 11 and the pressing belt 18 can have a slight speed difference. Similarly, the circumferential speed of the heating roll 12 and the pressing belt 20 can have a slight speed difference. Since the press belt and the heating roll have a larger friction, the laundry follows the pressing belt when there is a slight speed difference, thereby promoting the peeling of the laundry from the heating roll. You can plan. Moreover, the ironing effect by a heating roll can be anticipated because sliding generate | occur | produces between a laundry and a heating roll.

  Further, in the heating roll 11 and the pressing belt 18 and the heating roll 12 and the pressing belt 20, the heating roll 12 and the pressing belt 20 in the latter stage are slightly faster than the heating roll 11 and the pressing belt 18 in the preceding stage, respectively. Thus, the diameters of the sprocket 11b and the sprocket 12b are determined.

  By applying the rotational driving force from the motor 21 to the pressing belts 18 and 20 as described above, the pressing belts 18 and 20 are rotationally driven in addition to the frictional driving force from the heating rolls 11 and 12 and / or the laundry. Driven by force. Then, by rotating the pressing belts 18 and 20 at substantially the same rotational speed as the corresponding heating rolls 11 and 12, there is no need to adjust delicate tension such as the tension of the pressing belts 18 and 20, and the pressing belts and It is possible to prevent the laundry from being delayed and wrinkles from occurring without causing the laundry to slip.

  Further, in the heating roll 11 and the pressing belt 18 and the heating roll 12 and the pressing belt 20, the rotating speed of the heating roll 12 and the pressing belt 20 is slightly higher, respectively. When the leading end of the laundry that moves away from the heating roll 11 and moves on the pressing belt 18 is sandwiched between the heating roll 12 and the pressing belt 20 that rotate slightly faster, the heating roll 11 and the pressing belt 18 It will be pulled a little by the speed difference between the rear end parts to be sandwiched, and the laundry is easily peeled off from the heating roll 11, and the effect of stretching the basket is obtained. And since the laundry moves from the heating roll 11 to the heating roll 12 while the laundry is always pulled between the heating roll 11 and the heating roll 12, it is possible to prevent delay of peeling from the heating roll 11, Entrainment during conveyance can be prevented.

  In addition, since the heating rolls 11 and 12 and the motor 21 as a driving source for the pressing belts 18 and 20 are common, the driving of the heating rolls 11 and 12 and the pressing belts 18 and 20 is always synchronized. . However, the driving sources of the heating rolls 11 and 12 and the pressing belts 18 and 20 can be separate driving sources.

  Even when three or more heating rolls are used, similarly, the circumferential speeds of the subsequent heating roll and the pressing belt are respectively higher than the circumferential speeds of the preceding heating roll and the pressing belt. It should be set.

  FIG. 4 is a schematic side view showing a second embodiment according to the present invention. In the figure, the same members as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  In this embodiment, an air jet outlet 33 and a temperature sensor 34 are arranged side by side between the heating roll 12 and the outlet 13b along the laundry to be conveyed. The air jet outlet 33 blows an air flow from between the plurality of belts of the pressing belt 20 against the laundry that has passed through the heating rolls 11 and 12. The temperature sensor 34 measures the temperature of the laundry on which the air flow is blown in a non-contact manner.

  As shown in FIG. 5, the temperature sensor 34 is connected to a control unit 36, and the control unit 36 is connected to a motor adjustment circuit 38, and the motor 21 is driven by a signal from the motor adjustment circuit 38.

  The temperature sensor 34 may directly measure the temperature of the laundry without blowing the air flow, but by blowing the air flow, the temperature change of the laundry is promoted by the heat of vaporization, and the dry state is poor. A remarkable temperature difference can be obtained between cases and good cases.

  The measurement signal from the temperature sensor 34 is sent to the control unit 36, and the control unit 36 controls the signal to the motor adjustment circuit 38 in accordance with the measurement signal to control the rotation speed of the motor 21.

  As a control method, if the temperature detected by the temperature sensor 34 is low, the rotation speed of the motor 21 is slow, and if the temperature detected by the temperature sensor 34 is high, the rotation speed of the motor 21 is controlled to be high. Can do.

  For example, when the specified temperature is compared with the detected temperature and the detected temperature is lower than the specified temperature, the drying condition is insufficient, so the motor adjustment circuit 38 is driven to slow down the conveying speed and the motor is driven. Decrease the rotation speed of 21. By increasing the time during which the laundry is in contact with the heating rolls 11 and 12 in this way, appropriate drying can be performed. On the other hand, when the detected temperature is higher than the specified temperature, it is too dry, so that the motor adjustment circuit 38 is driven to increase the rotation speed of the motor 21 in order to increase the conveyance speed. Thus, by reducing the time for which the laundry is in contact with the heating rolls 11 and 12, appropriate drying can be performed, and the drying time can be reduced. As a specific method thereof, proportional feedback control or proportional-integral feedback control can be used.

  Alternatively, it is determined whether or not the temperature detected from the temperature sensor 34 is within a predetermined temperature range. If the temperature is within the predetermined temperature range, the conveyance speed is maintained, and if the temperature is lower than the predetermined temperature range, the motor is When the adjustment circuit 38 is driven to decrease the rotation speed of the motor 21 by a predetermined amount and is higher than the predetermined temperature range, the motor adjustment circuit 38 can be driven to increase the rotation speed of the motor 21 by a predetermined amount. .

  In this way, it is possible to improve and stabilize the finishing quality and improve the work efficiency by appropriately drying the laundry.

  FIG. 6 shows a modification of the second embodiment. In this modification, the air jet outlet 33 and the temperature sensor 34 are arranged to face each other with the laundry to be conveyed sandwiched between the heating roll 12 and the outlet 13b. The air jet outlet 33 blows an air flow from between the plurality of belts of the pressing belt 20 against the laundry that has passed through the heating rolls 11 and 12. The temperature sensor 34 measures the temperature of the airflow that hits the laundry and passes through the laundry. When the temperature measured by the temperature sensor 34 is low, a large amount of heat of vaporization is taken away by the laundry, and it is determined that the laundry is dry, and when the temperature measured is high, the heat of vaporization is generated. It is not deprived so much, and it is judged that the laundry is dry.

  Also in this modified example, the driving speed of the motor 21 can be changed according to the signal from the temperature sensor 34 in the same manner.

  In the second embodiment, a calendar type roll ironer has been described as an example. However, the present invention is not limited to this, and the present invention can be similarly applied to a bed type roll ironer. Since the laundry is conveyed while sandwiching the laundry with the heating bed, appropriate drying can be performed by controlling the rotation speed of the roll.

  The position of the temperature sensor can be arranged between the front roll and the rear roll, in addition to being arranged in front of the discharge port, depending on the drying condition of the laundry that has passed through the front roll. It is also possible to change the rotation speed of the entire roll.
