Description

  The present invention relates to a roll finishing machine for washing and drying linen items such as sheets, wrapping cloths, towels and the like used in hotels, hospitals, etc., and then continuously ironing them.

  A large amount of used linen items (laundries) such as sheets, wrappings, and towels used in hotels, hospitals, etc. are collected at a linen supply factory. In the linen supply factory, the collected used linen products are washed and dried, and then ironed by a roll finishing machine (roll ironer). Linen products that have been ironed after being washed and dried at the linen supply factory are delivered to hotels, hospitals and the like.

  In the linen supply factory, towels are completely dried by a dryer. So-called flat objects such as sheets, wrapping, and pillowcases are wrinkled and ironed (ironing). For this reason, so-called flat objects such as sheets, wrapping sheets, pillow covers, etc. are taken out of the dryer in a slightly moist state. Sheets, wrappings, and pillowcases taken out of the dryer in a slightly wet state are “wrinkled” and “finish dried” by a roll finisher.

  There are chest type and calendar type roll finishing machines that perform ironing. Patent Documents 1 and 2 propose a chest type roll finishing machine. The chest type roll finishing machine has a heated heating bed and a roll that rotates while pressing a linen product against the heating bed. The sheets, wrapping cloth, pillow covers, etc. in a slightly moist state conveyed between the heating bed and the roll are conveyed by the rotation of the roll while being pressed against the heating bed by the roll. As a result, a large pressing force (pressing force) is applied to the sheets, the wrapping cloth, the pillow cover, etc., so that the sheets are “wrinkled and stretched”, and “finish drying” is performed by the heating bed.

  In such a chest type roll finishing machine, a plurality of finishing machines each consisting of a heating bed and a roll are used in order. Linen products are sequentially transported between the heating bed and roll of the previous stage and between the heating bed and roll of the next stage. The rotation speed of the next-stage roll is set faster than the rotation speed of the previous-stage roll. Thereby, since tension (tension) is given to the linen article conveyed in order between a plurality of heating beds and rolls, generation of wrinkles during conveyance is prevented. As described above, since it is necessary to apply tension (tension) so that wrinkles are not generated in the linen product during transportation, a roll finishing machine generally requires a plurality of finishing machines including a heating bed and a roll. .

Closely arranged Is characterized in that the conveying path the linen products transported to the entrance is provided a pressing roller that presses into the transport support base side.

  Further, according to one aspect of the present invention, the pressing roller includes a roller disposed in parallel with the main roll, a driving unit that presses the roller toward the conveyance support base, and a shaft of the driving unit and the roller. It is preferable to include a pressing lever that is connected to the direction end portion and swings by the driving force of the driving unit to move the roller to the transport support base side.

  As an aspect of the present invention, it is preferable that the roller has a pressing outer periphery formed of a material having at least an outer peripheral surface having elasticity.

  Moreover, as one aspect of the present invention, the heating bed supports a heating plate having an elongated shape and an arc-shaped cross section intersecting the longitudinal direction, and both sides of the heating plate in the longitudinal direction. It is preferable to include a side plate portion that performs heating and a heating portion that is provided on the back side of the heating bed and heats the heating plate.

  According to the present invention, the pressure roller is provided near the entrance of the linen product conveyance path and close to the main roll to press the linen product toward the conveyance support base. For this reason, a linen article can be conveyed between a main roll and a heating bed in the state which gave tension to a linen article. In particular, the generation of wrinkles at the rear end of the linen product can be prevented. Further, when the linen product is transported in the transport path, a tension is always applied to the linen product by the pressing roller. For this reason, it is not necessary to apply tension to the linen article using a plurality of main rolls. Thereby, the number of main rolls can be reduced. Therefore, large power for rotating the main roll is not required.

The main roll 7 is rotationally driven in one direction (conveying direction in which the linen product 4 is conveyed) by a driving force from the rotation driving unit. The main roll 7 forms a transport path 6 through which the linen product 4 is transported between the main roll 7 and the surface 3 of the recess 2 of the heating plate 13. The linen product 4 transported by the transport mechanism 11 is inserted into the transport path 6 from the entrance 8.

[Transport mechanism]

  The transport mechanism 11 includes a transport support base 9, a transport belt 10, and a driving roller 20. The conveyance support base 9 is disposed in the vicinity of the entrance 8 of the conveyance path 6. A conveyor belt 10 is wound around the conveyor support base 9. The conveyor belt 10 is composed of a plurality of strip-shaped strip belts. The plurality of strip belts are respectively wound around the driving roller 20 to form the conveying belt 10. The conveyor belt 10 moves as the driving roller 20 is driven to rotate. By moving the transport belt 10, the linen product 4 placed on the transport belt 10 is transported from the entrance 8 between the surface 3 and the pressing outer periphery 19 of the main roll 7. Further, the linen product 4 conveyed to the vicinity of the entrance 8 is pressed toward the conveyance support base 9 by the pressing roller 12.

(Pressing roller)
The pressing roller 12 is formed by a roller 21 disposed in parallel with the main roll 7 and a drive unit 22 that presses the roller 21 toward the conveyance support base 9. The roller 21 is formed of a material having at least an outer peripheral surface having elasticity, for example, rubber or sponge. The roller 21 is brought into contact with and separated from the conveyance support base 9 by driving units 22 and 22 (only one driving unit 22 is shown in the drawing) provided on the support side units 30 and 30, respectively.

  Since the drive units 22 and 22 provided in the support side units 30 and 30 have the same configuration, only one drive unit 22 will be described here. As shown in FIG. 2, the drive unit 22 is formed by an air cylinder 25 and a pressing lever 23. The air cylinder 25 has a rear end portion 24 that is rotatably supported by the support side portion 30. One end of the pressing lever 23 is rotatably connected to the terminal 26 a of the drive shaft 26 of the air cylinder 25. Further, the other end of the pressing lever 23 is rotatably supported by a support shaft 27 supported by the support side portion 30. Similarly, the other drive part 22 is also formed. The pressing levers 23 and 23 of the drive units 22 and 22 rotatably support the support shafts 21a and 21a provided at both ends of the roller 21 in the axial direction.

  When the drive shaft 26 of the air cylinder 25 is retracted into the cylinder (shown by a two-dot chain line in FIG. 2), when the drive shaft 26 protrudes outside the cylinder, the pressing lever 23 is centered on the support shaft 27. Swing. When the pressing lever 23 swings, the roller 21 moves from the position away from the transport support base 9 to the transport support base 9 side. In a state where the drive shaft 26 completely protrudes from the cylinder (a state indicated by a solid line in FIG. 2), the roller 21 presses the linen product 4 on the transport belt 10 onto the transport support base 9.

  Next, a transport operation for transporting the linen product 4 to the roll finisher 1 will be described. The linen product 4 placed on the transport belt 10 is transported onto the transport support 9 by the movement of the transport belt 10 and then sent to the entrance 8 of the transport path 6. Thereafter, the leading end portion (the leading end portion in the transport direction) of the linen product 4 sent to the entrance 8 of the transport path 6 is inserted into the transport path 6 from the entrance 8. That is, the front end portion of the linen product 4 is inserted between the pressing outer periphery 19 of the main roll 7 and the surface 3 of the recess 2 of the heating plate 13.

  The main roll 7 rotates while pressing the linen product 4 against the surface 3 of the heating plate 13. When the main roll 7 rotates while pressing the linen product 4 against the surface 3 of the heating plate 13, the linen product 4 is drawn into the transport path 6. When the leading end of the linen article 4 is drawn into the conveyance path 6, the drive shaft 26 of the air cylinder 25 protrudes from the cylinder, swings the pressure lever 23, and moves the pressure roller 12 toward the conveyance support base 9.

  As a result, the linen product 4 is pressed onto the conveyance support table 9. When the linen product 4 is pressed onto the transport support base 9, the leading end of the linen product 4 is transported while being slid in the transport path 6 while being pressed by the rotation of the main roll 7. Thereby, tension is applied to the linen product 4 between the pressing roller 12 and the entrance 8 of the conveyance path 6. With the tension applied, the linen product 4 is inserted into the conveyance path 6 and conveyed while being slidably pressed while being pressed by the main roll 7 toward the surface 3 side. By being brought into sliding contact with the main roll 7 while being pressed toward the surface 3, the wrinkles of the linen product 4 are stretched and ironed.

  As described above, in the roll finishing machine 1 according to the present embodiment, the linen product 4 is pressed toward the conveyance support base 9 near the main roll 7 in the vicinity of the entrance 8 of the conveyance path 6 for the linen product 4. A pressing roller 12 is provided. For this reason, it can convey between the main roll 7 and the concave chest 5 in the state which provided the tension | tensile_strength for the linen goods 4. FIG. In particular, the generation of wrinkles at the rear end of the linen product 4 can be prevented.

  In the roll finishing machine 1 of the present embodiment, when the linen product 4 is transported into the transport path 6, tension is always applied to the linen product 4 by the pressing roller 12. As a result, since it is not necessary to apply tension to the linen product 4 using a plurality of main rolls 7, the number of main rolls 7 can be reduced. Therefore, large power for rotating the main roll 7 is not required. In addition, since a large amount of power is not required, the roll finishing machine itself can be reduced in size. In addition, since no large power is required, the power consumed by the motor that rotationally drives the main roll 7 can be reduced. Furthermore, since it is not necessary to adjust the rotational speed of the preceding and next rolls, it is not necessary to adjust the rotational speed of the motor that rotationally drives the rolls.

  In the above embodiment, an example in which the present invention is applied to a chest type roll finishing machine has been described. However, the present invention can also be applied to a calendar type roll finishing machine. Moreover, in the said embodiment, although the pressure roller 12 showed the example which has arrange | positioned one roller along the longitudinal direction A, you may provide two or more pressure rollers, and it follows the longitudinal direction A. A plurality of divided rollers may be arranged along the longitudinal direction A. Further, in the above-described embodiment, the example in which the air cylinder 25 is used as the driving unit 22 and the pressing roller 12 is brought into contact with and separated from the conveyance support base 9 has been described. Other means may be used for the drive unit to be brought into contact with and separated from.

  Although the embodiments of the present invention have been disclosed as described above, it is obvious that those skilled in the art can make changes without departing from the scope of the present invention. All such modifications and equivalents are intended to be included in the following claims.

  The present invention can be used not only for a chest type roll finishing machine but also for a calendar type roll finishing machine, and transports sheets called so-called flat objects, wrapping cloths, pillow covers, etc. in a tensioned state. It can be used for a device to perform.
