1. Field of Invention
This invention relates to a laundry press finishing device, which is, in particular, one preferably formed to press finish laundry with the surface like such as sheets, table clothes, handkerchieves and like.
2. Related Art of Invention
As this type of conventional devices, there has already been provided with the laundry pressing finishing machine, as described in U.S. Pat. No. 4,280,290, for example, which comprises a lower iron on which the laundry is mounted and an upper iron for depressing the upper surface of the lower iron to press finish the laundry.
Conventionally, in this type of prior art device, when a long-sized laundry such as sheets was to be press finished, it was necessary to repeat such operations as one in which at first a part of the sheets was pressed with the upper iron and then the position of the sheets was displaced and set again and after this work, the upper iron was lowered again to press against the sheets.
Accordingly, in the case that this type of laundry was to be press finished with the prior art pressing machine, there occurred some problems that it required a tremendous amount of labor and time.
Additionally, as described above, since it was necessary to lift up or lower the upper iron several times, there could easily occur some troubles that an operator's head or hands were held by accident with the upper iron and got scaled in touch with the upper iron.
In addition, the prior art pressing machine showed a poor working efficiency and also a poor convenience in use when a pressing work for the sheets was started because the operator usually could not move away from the machine and could not perform other works.
Further, this type of prior art pressing machine frequently showed a case in which the upper iron was installed near a position where the operator stood for setting the laundry at the lower iron. Accordingly, the prior art machine sometimes showed a dangerous state in which the operator's head or the like got scaled with the upper iron when the operator set the laundry on the lower iron.
In view of some circumstances as found in the prior art pressing machine, this invention has been invented.
Accordingly, a technical problem to be resolved by this invention consists in enabling the plane laundry such as the sheets or handkerchief or the like to be press finished safely without any troublesome work.
In order to resolve the aforesaid problems, this invention provides such technical means as follows.
That is, as shown in
In this invention, although the driving device is usually constituted by a rotating force generating machine such as an electric motor and the like, it may also be applicable that this driving device is constituted under a combination of a cylinder and a device for changing a linear motion of a rod in the cylinder into a rotating motion. The transmittance member is constituted by a belt or a chain, for example and the controller is constituted by a microcomputer and a sequencer. The predetermined length defined in this case is meant practically to be the same one as a width of the iron surface of the upper iron in a forward or rearward direction or a length slightly shorter than that. This value is set for preventing a part not to be pressed in the laundry from being generated when the laundry is sent intermittently and pressed with the upper iron.
Additionally, although the transmittance wheels in this invention are arranged at the front and rear positions of the lower iron, it may also be applicable that they may be provided with a tension wheel, for example. In addition, this invention may also be applicable in such a way as that it is combined with a device for supplying the laundry to the upper surface of the lower iron or the lower iron is formed into a vertical elongated shape as seen from its side surface to cause the laundry to be sucked to the moving cover, for example, then the laundry to be sent from below toward the upper surface of the lower iron and the laundry to be press finished with the upper iron.
This invention is preferably to arrange that a length of the upper surface of the lower iron in a forward or rearward direction is formed to be longer than a width of the iron surface of the upper iron in a forward or rearward direction and that the iron main body is position set at the rear side.

Additionally, in this case, since the upper iron becomes to be arranged at the rear side of the device in correspondence with the iron main body, occurrence of trouble in which the operator's head or hands are contacted with the upper iron when the operator sets the laundry onto the upper surface of the lower iron can be reduced more and correspondingly the setting work can be carried out safely.
Further in this case, as shown in
Since the laundry is sent while being raised, no wrinkle is generated at the laundry, but the laundry can be sent regularly and correspondingly the laundry can be press finished in a neat manner. In addition, in accordance with operation, it is possible to arrange the upper iron at the high position of the rear side of the device and it can be used more safely.
In addition, this invention preferably comprises that a feeder device for receiving the press finished laundry dropped from the rear side of the lower iron and feeding it to a recovery location is provided and formed.
By the above device, the press finished laundry can be received easily and quickly.
