Description

The present invention relates to a roll ironer for ironing water-washed laundry, which is mainly called a linen product such as sheets and pillowcases, and particularly from a chest-type ironer press roll to laundry (hereinafter, "covered"). It relates to the above-mentioned device suitable for peeling and sending out "laundry" and a roll ironer provided with the device.

Roll ironers that are installed in commercial laundry lines to smooth out wrinkles of washed linens are roughly classified into chest type ironers and calendar type ironers. The chest-type ironer is washed between a heating bed (chest) provided with a recess having a semicircular cross section and a peripheral surface provided with a cushion layer of a press roll that rotates in contact with the inner peripheral surface of the recess. It is a device that feeds an object and transfers the object to be washed pressed against the inner peripheral surface of the chest by the compressive elasticity of the cushion layer by the rotation of a press roll to smooth out wrinkles (ironing). The chest-type ironer has the characteristic that the surface of the wrinkled object to be washed becomes glossy, but the device is large and the power consumption of the transfer motor is about 10 times larger than that of the calendar-type ironer because it is rubbed and sent. It has the disadvantages of high steam consumption and damage to the object to be washed.

On the other hand, the calendar type ironer has a plurality of rotary heating rolls heated by putting steam inside, and a presser belt that is hung on these heating rolls and circulates at a synchronous speed while pressing the object to be washed against the peripheral surface of the heating roll. The front and back surfaces of the object to be washed are alternately pressed against the surfaces of a plurality of heating rolls to smooth out wrinkles and dry the finish. The calendar type ironer is inferior to the chest type ironer in the gloss of the surface of the object to be washed, but it is characterized by relatively inexpensive equipment, high productivity, low energy consumption, and excellent drying performance of thick materials. be.

Recently, as a roll ironer with a structure that is a compromise between the conventional chest type ironer and the calendar type ironer, a roll ironer that first irons with the chest type and then irons with the calendar type has been proposed. ..

On the other hand, as a common problem with roll ironers, there is a problem of how to peel the object to be washed from the roll (press roll and heating roll) at the outlet of the chest or the heating roll without causing wrinkles. .. The object to be washed easily sticks to the chest-type press roll that feeds the object to be washed due to the frictional force (adhesive force) on the surface of the roll, and also easily sticks to the first-stage roll having a high water content of the object to be washed. Therefore, in a roll ironer that is a compromise between a chest type and a calendar type, the problem is how to peel the object to be washed from the press roll at the outlet of the chest.

As a means for peeling the object to be washed from the press roll at the outlet of the chest, a structure is known in which a plurality of thin and narrow guide tapes are passed between the object to be washed passing through the chest and the press roll. As shown in FIG. 5, the guide tape 54 that has moved between the chest 51 and the press roll 52 together with the object to be washed is guided by the guide roller 53 in a direction away from the press roll 52, so that the object to be washed w is moved away from the press roll 52. Forcibly separates from the surface of the press roll 52.

The structure using this guide tape can surely peel off the object to be washed from the press roll, but there is a problem that the trace of the guide tape remains on the ironed object to be washed. Further, since the thin guide tape is heated between the chest 51 and the press roll 52 together with the object to be washed with water remaining, the life of the guide tape is short, and a plurality of guide tapes can be used. There is a problem that the exchange is also troublesome.

On the other hand, as a means for peeling the object to be washed without using a guide tape, a structure has been proposed in which a negative pressure roller or a negative pressure box is provided at the outlet portion of the chest and the object to be washed is peeled from the guide roll by these negative pressures. (Patent Documents 1 and 2). Negative pressure boxes and negative pressure rollers are provided with a large number of through holes on the peripheral surface facing the outlet of the chest, and a transport belt provided with a large number of through holes is hung around the peripheral surface to pass through these through holes. By sucking air, the object to be washed is peeled off from the press roll and adsorbed on the transport belt side.

Among these structures, those using a negative pressure box have a shape in which a through hole for sucking air can be provided only in a portion facing the outlet of the chest, and a surface having the through hole is matched with the outlet shape of the chest. Therefore, the object to be washed can be peeled off from the press roll with a small-capacity blower. However, since the transport belt on which a much larger tension is applied than the guide tape slides and moves on the peripheral surface of the negative pressure box, there is a problem that the wear of the transport belt and the power loss are large.

On the other hand, in a structure using a negative pressure roller, a through hole must be provided on the entire circumference of the roller, and only a part of the peripheral surface performs the peeling action of the object to be washed, so a large-capacity blower must be used. It is inefficient. Therefore, a proposal was made to reduce the capacity of the blower by blowing air from above between the peripheral surface of the press roll and the object to be washed attached to it to assist the suction force of the negative pressure roll. (Patent Document 1).

However, in the structure that peels the object to be washed from the press roll using negative pressure, lint (fiber dust) adhering to the object to be washed and lint floating in the surrounding air are also sucked together with the air. , The filter attached to the blower that generates negative pressure is clogged, and it is usually necessary to clean the filter about once a day, which causes a problem that maintenance is troublesome. Further, in the structure in which the object to be washed is separated from the press roll by the combination of the negative pressure and the jet, the distortion of the object to be washed occurs when the object to be washed is pushed back by the jet flowing in the direction opposite to the sending direction of the object to be washed. Is attracted and fixed on the transport belt, which may cause wrinkles in a later process.

As described above, various structures have been proposed as structures for peeling the object to be washed from the press roll at the outlet of the chest of the chest type ironer, but there are still problems to be solved in each structure.

The present invention is intended to provide a particularly suitable technical means for peeling an object to be washed from a press roll at the outlet of a chest-type ironer and delivering it to a transport belt by an action different from that of a conventional structure.

In the present invention, between the peripheral surface of the press roll 12 of the chest type ironer and the tip end side of the object to be washed w sent from the chest 11 from the air nozzle 43 arranged above the object to be washed outlet 15 of the chest type ironer 1. The jet stream a is blown to peel the object to be washed w from the peripheral surface 16 of the press roll 12, and the tip of the object to be washed w is caused by the inverted air flow between the tip side of the peeled object w to be washed and the press roll 12. The side is sent out onto the transport belt 3, and the guide tape 4 attached to and circulates on the transport belt 3 prevents the object to be washed w from floating on the transport belt 3, so that the object to be washed w is wrinkled. The above problem is solved by sending out from the chest type ironer without causing the above problem.

That is, the object to be washed delivery device of the present invention is a device that sends the object to be washed w delivered from the outlet 15 of the chest type ironer 1 to a transport belt 3 provided in the vicinity of the outlet, and is a device to send the object to be washed 15 to the outlet 15 to be washed. An air nozzle 43 that flows along the peripheral surface of the press roll 12 of the chest type ironer from above and blows a jet flow a between the peripheral surface 16 and the tip end side of the object to be washed w sent from the chest, and the ironer 1. It is provided with a guide tape 4 that circulates above the transport belt 3 without passing through 2 and 2 and is attached to the upper surface of the transport belt 3 in the immediate vicinity of the outlet 15.

As the guide tape 4, it is preferable to use a plurality of thin narrow tapes arranged at intervals, but a tape having the same width as that of the transport belt 3 can also be used. The guide tape 4 circulates from above to below the object to be washed outlet 15 of the chest 11, is folded back by a folding guide 40 arranged immediately above the outlet, and is attached on the transport belt 3.

The roll ironer of the present invention includes a chest unit 1 that irons with a chest type, a calendar unit 2 that irons with a plurality of heating rolls in a calendar type, and a front end of the chest unit of the chest 11 close to the object to be washed outlet 15. Attached to the transport belt 3 which is folded back at and transports the object w to be washed from the chest unit 1 to the calendar unit 2 and the upper surface of the transport belt 3 immediately after being folded around at the front end of the transport belt 3. The guide tape 4 is provided, and the air nozzle 43 that blows the jet flow a between the peripheral surface 16 of the press roll 12 of the chest unit and the tip end side of the object w to be washed sent from the chest from above the outlet 15 to be washed. I have.

In the present invention, the object to be washed w is formed on the peripheral surface 16 of the press roll by causing a jet flow a to act between the peripheral surface 16 of the press roll 12 and the tip end side of the object to be washed w sent to the chest outlet 15. It is peeling off from. The jet flow a flows along the peripheral surface 16 of the press roll 12 and peels off the tip end side of the object to be washed w from the peripheral surface. When the object to be washed w is separated from the peripheral surface 16 of the press roll, the jet a that has flowed in between the peripheral surface and the separated object to be washed is prevented from flowing downward, so that the jet flow a is reversed and the object to be washed is inverted. It flows in the sending direction. Since this flow is in the same direction as the feeding direction of the object to be washed and is faster than the feeding speed of the object w to be washed, the tip side of the object to be washed is on the transport belt 3 without wrinkles due to the inverted air flow. Is sent to.

According to the tests by the inventors of the present application, in the case of ironing sheets, when the transport speed of the object to be washed by the chest unit 1 is slow, for example, when the feed rate of the object to be washed is about 25 m / min or less. By the above action, the tip of the object to be washed could be sent out onto the transport belt 3. However, at a speed of, for example, 40 m / min or more, the tip of the object to be washed was lifted at the chest outlet as shown in FIG. 3, and wrinkles were generated due to this lift. In the present invention, by suppressing this floating with the guide tape 4, it is possible to convey the object to be washed w peeled off from the press roll 12 of the chest unit 1 to the calendar unit 2 at high speed without causing wrinkles. rice field.

As will be understood in the above description, although the guide tape 4 is used in the present invention, the guide tape can be constructed so as not to pass through the chest 11 and the heating roll 5, and the guide tape 4 conveys the object to be washed. Since it only prevents the tape from floating on the belt, no tape marks are left on the object to be washed, and the guide tape is less damaged.

In addition, since a blower that generates negative pressure is not required and only the air flow that is ejected is used, the capacity of the blower may be small, and there is no need to provide a through hole in the transport belt, so that the equipment cost is low. The life of the transport belt is not shortened, and the number of steps required for cleaning the filter and the number of maintenance tasks required for replacing the guide tape can be reduced.

Hereinafter, embodiments of the present invention will be described by taking as an example a roll ironer including a chest unit 1 for ironing an object to be washed with a chest type and a calendar unit 2 for ironing with a calendar type.

With reference to FIG. 1, the chest unit 1 is a one-stage chest-type ironer having a chest (heating bed) 11 having a semi-cylindrical recess 13 and a chest (heating bed) 11 inserted into the recess 13 to feed the object to be washed. It is provided with a press roll 12 that rotates in the direction of arrow r in the figure. Although details are not shown in the figure, the chest 11 and the press roll 12 are similar to those of the chest type ironer having a conventional structure, and the inner peripheral surface of the recess 13 is a trowel surface, and the chest 11 and the press roll 12 are formed on the peripheral surface of the press roll 12. Is provided with a cushion layer.

The chest unit 1 is provided with a loading conveyor 14 for the object to be washed, and the object insertion port of the chest 11 is provided with a photoelectric sensor 17 for detecting the tip end side of the object to be inserted. The object to be washed, which has been washed with a water washing machine (not shown) and adjusted to a predetermined water content by a dehydrator and a dryer, is inserted between the chest 11 and the press roll 12 by the loading conveyor 14, and is rotated by the press roll 12. It is sent to the right in FIG. 1 and the first stage ironing is performed. The object to be washed that has passed through the chest unit 1 is transported to the calendar unit 2 by the transport belt 3 facing the outlet 15 of the chest 11.

The front end roller 31 of the transport belt 3 faces the object to be washed outlet 15 of the chest 11. A dropout prevention belt 33 is provided at the rising portion of the transfer belt 3 to prevent the object to be washed from falling off from the transfer belt. An air nozzle 43 is provided above the object to be washed outlet 15 of the chest so that the nozzle hole faces the press roll peripheral surface 16 side of the outlet. A guide tape 4 is attached to the upper surface of the transport belt 3 near the outlet 15.

The guide tape 4 shown by the broken line in the figure is provided so as to circulate along the upper surface of the transport belt 3 from the outlet 15 of the chest to the rear end of the fall-out prevention belt 33 at the same speed as the transport belt 3. The guide tape 4 is provided so as to come down from above at the outlet 15 portion of the chest, be folded back into an L shape by the folded guide 40, and be attached to the upper surface of the transport belt 3. Therefore, the object to be washed sent out from the outlet 15 of the chest is conveyed by the conveying belt 3 with the upper surface pressed by the guide tape 4. At the rising portion of the transport belt 3, the guide tape 4 passes between the transport belt 3 and the dropout prevention belt 33.

The guide tape 4 of the embodiment is a narrow tape, and a plurality of guide tapes 4 are provided at intervals. In the example of FIG. 1, the guide tape 4 is hung between the rollers 34, 35, the sliding guide 46, and the folding guide 40, and circulates at the same speed as the falling-out prevention belt 33 and the transport belt 3. When the chest unit 1 and the calendar unit 2 are separated from each other, it is preferable to provide a guide tape 4 on the transport belt 3 and an auxiliary roller 47 for suppressing the lifting of the object to be washed w, as shown in FIG. ..

The route from the other peripheral circuit of the guide tape 4, that is, the auxiliary roller 47 to the rollers 34, 35 of the fall prevention belt and the sliding guide 46 above the chest outlet can be freely set. In the example of FIG. 1, by adopting the above-mentioned peripheral circuit, the guide tape 4 can be driven by the same drive roller as the fall prevention belt 33.

The calendar unit 2 includes four heating rolls 5a to 5d rotating in the direction of the arrow s in FIG. 1, and pressing belts 6a to 6d for pressing the object to be washed on these rolls. The object to be washed introduced from the carry-in port 22 is pressed against the surface of the heating roll 5 and ironed while being conveyed by the presser belt 6, and is carried out of the device from the discharge port 23. Each heating roll 5 has the same diameter, and the first heating roll 5a and the second heating roll 5b located on the upstream side of the object to be washed passage are located above the back side when the first heating roll 5a is viewed from the carry-in inlet 22 side. The second heating roll 5b is arranged so as to be located below the front side. The lower part of the first heating roll 5a and the upper part of the second heating roll 5b have substantially the same height.

The pair of the third heating roll 5c and the fourth heating roll 5d is arranged below the pair of the first and second heating rolls in the same positional relationship as the positional relationship between the first heating roll and the second heating roll. That is, the third heating roll 5c and the fourth heating roll 5d are positioned directly below the first heating roll 5a and the second heating roll 5b, respectively, and the lower part of the third heating roll 5c and the upper part of the fourth heating roll 5d are abbreviated. They are arranged at the same height.

The holding belts 6a to 6d of the heating rolls 5a to 5d are provided around the circumference of each heating roll between the inlet rollers 7a to 7d located at the upper part of each heating roll and the outlet rollers 8a to 8d located at the lower part of each heating roll. Attached to the surface. The presser belts 6a to 6d are guided by a plurality of free-rotating rollers including tension adjusting rollers and drive rollers, and return from the outlet rollers 8a to 8d to the inlet rollers 7a to 7d. In the figure, the rollers indicated by double circles are rollers with flanges that prevent the presser belt from meandering. The outlet rollers 8a to 8c are small-diameter rollers provided on the tip end side of the support plate and are called knife edges.

The object to be washed, which has been thrown into the object to be carried-in port 22 of the calendar unit 2 by the transport belt 3, is sent to the first heating roll 5a, and is first heated by the pressing belt 6a between the inlet roller 7a and the outlet roller 8a. The lower surface (the surface that becomes the surface of the object to be washed as a product) that is pressed against the roll 5a and ironed by the chest 11 is ironed, and is conveyed to the upper part of the second heating roll 5b by the pressing belt 6a. Next, the back surface of the object to be washed is pressed against the second heating roll 5b between the inlet roller 7b and the outlet roller 8b of the second heating roll, and the back surface is ironed. Further, the front and back surfaces are pressed against the third heating roll 5c and the fourth heating roll 5d between the inlet rollers 7c and 7d and the outlet rollers 8c and 8d, respectively, and the calendar unit is ironed for the second time and discharged. It is carried out of the aircraft from the exit 23.

That is, the object to be washed passing through the roll ironer of FIG. 1 is ironed once by the chest type in the chest type unit of the first stage, and then four heating rolls are carried out in the calendar unit 2 of the next step. It is ironed four times by the calendar type and discharged.
In the calendar unit 2 of the illustrated embodiment, the front and back surfaces of the object to be washed are alternately pressed against the peripheral surfaces of the four heating rolls to perform ironing. Then, the object to be washed pressed against each heating roll 5 separates from the peripheral surface of the heating roll at the lower part of the heating roll. A guide tape for preventing sticking is not provided between each heating roll 5 and the corresponding pressing belt 6, but gravity acts on the object to be washed in a direction away from the peripheral surface of the heating roll. This gravity promotes smooth peeling of the object to be washed from the peripheral surface of the heating roll.

In the calendar unit 2 of the illustrated embodiment, the pair of the first heating roll 5a and the second heating roll 5b is arranged above the pair of the third heating roll 5c and the fourth heating roll 5d, so that the installation floor area of the apparatus is reduced. The length of the presser belt can be shortened. Further, the in-flight air heated by the third and fourth heating rolls flows upward to heat the arrangement space of the first and second heating rolls. Therefore, heat dissipation from the first heating roll and the second heating roll into the air is reduced, and the energy consumption required for heating the heating roll can be reduced.

Furthermore, since the number of heating rolls is 4, the diameter of the heating roll can be reduced while securing the required ironing area, and the first heating roll and the second heating roll can be placed above the third heating roll and the fourth heating roll. It is also possible to prevent the height of the apparatus and the height of the carry-in entrance 22 of the object to be washed from becoming excessive when arranged.

Next, the delivery structure of the chest unit from the press roll 12 to the transfer belt 3 will be described in detail with reference to FIG. A front end roller 31 of a conveyor belt is arranged at the outlet 15 of the chest, and the conveyor belt 3 is hung around the roller 31 and circulates in the direction of arrow t in the figure. A lower guide 42 is fixedly provided between the front end roller 31 and the press roll 12, and an upper guide 41 is provided above the lower guide 42. An air nozzle 43 for ejecting an air flow downward is provided on the press roll side of the upper guide 41.

Both the upper guide 41 and the lower guide 42 are plate-shaped members, and the lower side of the upper guide 41 is bent in a U shape to form a folded guide 40 of the guide tape 4. That is, the guide tape 4 that has been circulated from above is folded back by the folding guide 40 and folded back in the direction of discharging the object to be washed at a height attached to the upper surface of the transport belt 3. The lower guide 42 is bent in an arc shape so that the object to be washed peeled from the press roll 12 is smoothly guided to the transport belt 3.

The folded guide 40 of the illustrated embodiment is a sliding guide formed by bending the lower side of the plate-shaped upper guide 41 in a U shape or 180 degrees (see FIG. 4), but a wide range of tapes can be used as the guide tape 4. When used, it can be a free-rotating roller, and a plate-shaped upper guide 41 can be not provided.

A slit 45 through which the object to be washed passes is formed between the folded-back guide 40 and the upper side of the lower guide 42, and a V-shaped peeling region is formed between the lower guide 42 and the peripheral surface 16 of the press roll 12 in a side view. 44 is formed. Above the peeling region 44, an air nozzle 43 having a plurality of nozzle holes facing downward is provided. The air nozzle 43 is provided so that the air flow ejected from the nozzle hole flows into the peeling region 44 from the peripheral surface 16 side of the press roll 12. That is, the direction of the jet flow a from the air nozzle 43 is biased toward the peripheral surface side of the press roll from the tangential direction of the press roll 12, and after the jet flow comes into contact with the peripheral surface of the press roll, a large turbulence is generated. Instead, it flows along the peripheral surface of the press roll and flows toward the outlet 15 of the chest.

Next, the operation of delivering the object to be washed from the chest in the roll ironer of the present invention will be described. In a controller (not shown), the time from when the tip edge detection sensor 17 of the object to be washed detected in the chest unit 1 detects the tip edge of the object to be washed reaches the outlet 15 of the chest is the time for the chest 11 to be washed. Calculated from the moving distance of the object and the rotation speed of the press roll 12, air injection from the air nozzle 43 is started before the tip of the object to be washed reaches the outlet 15 of the chest, and the tip side reaches the outlet 15 by several cm to several centimeters. The air injection is stopped at the timing when it has passed 10 cm. The air flow a ejected from the air nozzle 43 flows along the peripheral surface 16 of the press roll and is blown into the peeling region 44 formed by the lower guide 42 and the peripheral surface 16 of the press roll. When the tip side of the object to be washed is sent out to the portion of the peeling region 44, the tip side of the object to be washed w is moved from the peripheral surface 16 of the press roll by the jet a flowing along the peripheral surface 16 of the press roll. It is peeled off and pressed against the lower guide 42 side.

When the tip end side of the object to be washed is separated from the press roll 12, the jet flow a that has flowed along the peripheral surface of the press roll is prevented from flowing downward by the peeled object to be washed. It flows to the slit 45 side between the lower guide 42 and the lower guide 42. Since the direction of this flow is the same as the feeding direction of the tip side of the object to be washed peeled from the press roll 12 and faster than the feeding speed of the object w to be washed, the tip side of the object to be washed has an inverted air flow. It is sent out onto the transport belt 3 without causing wrinkles. The tip end side of the delivered object w to be washed is delivered to the transport belt 3 in a state of being sandwiched between the transport belt 3 and the guide tape 4 without causing a floating or wavy phenomenon.

FIG. 4 is a diagram showing a second embodiment of the object to be fed structure of the roll ironer of the present invention. The difference from the first embodiment shown in FIG. 2 is that the guide tape 4 circulates between the upper guide 41 and the air nozzle 43.

The positional relationship between the air nozzle 43 arranged between the upper guide 41 and the peripheral surface 16 of the press roll and the path of the guide tape 4 does not differ greatly regardless of which is provided on the press roll 12 side, but the guide tape 4 In the structure of the second embodiment in which the passage is provided between the upper guide 41 and the air nozzle 43, the jet flow a from the air nozzle does not collide with the guide tape 4 and a part of the air nozzle 43 is not disturbed. Nozzle holes can be arranged more freely. Further, the guide tape 4 can be made into a single tape having a width equal to that of the transport belt 3, and in that case, the jet flow is guided by the guide tape that circulates from above to the folded guide 40, so that the jet shape is plate-shaped. It is also possible to have a structure in which the upper guide is not provided.

As understood from the above description, the mechanism for feeding the object to be washed from the chest in the roll ironer of the present invention is not a method of peeling the object to be washed from the peripheral surface of the press roll with a guide tape or negative pressure. The jet that flows along the peripheral surface of the roll separates the object to be washed from the peripheral surface of the roll, and the jet that flows in the direction opposite to the feeding direction of the object to be washed causes wrinkles in the object to be washed. Even if the object to be washed is received by the transport belt, the swell or the object to be lifted is extended so that the object to be washed can be sent out from the chest without wrinkles. Therefore, there is an effect that it is possible to solve a problem that could not be solved by a structure based on a conventional technical claim, and to provide a roll ironer having a simpler structure and excellent durability and maintainability.
