Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an ironing board in which the intake action of outside air by an intake device housed in an ironing board can be automatically controlled in accordance with the work process.

[Conventional technology]

A conventional ironing board will be explained with reference to FIG.

Reference numeral 1 denotes a breathable part on which a work is placed, and is supported by a stepped part 4 so as to be placed above an opening 3 of a base body 2. An intake fan 6 is disposed in the central duct 5 of the opening 3, and a motor 7 that is pivoted to the fan 6 is housed in the base body.
This fan 6 and motor 7 constitute an intake device A.

By stepping on the foot switch 18 or operating an iron switch (not shown) attached to the iron to turn it on, the motor 7 is driven and the outside air can be sucked into the base 2 from the part 1.

This suction device A is driven with different suction forces having different strengths as follows, corresponding to the work process of applying an iron press to a workpiece as a material to be ironed.

(1) Work set...It is driven by the setting suction force to prevent the work from shifting or curling when setting the work in the part 1, and is operated by the foot switch 18.

(2) Iron press: When pressing a work with a steam iron, it is driven by iron suction power and is operated by an iron switch.

(3) After-vacuum...This is a device that is driven by after-suction power when removing moisture from a workpiece after iron pressing, and when the iron switch is pressed.
After being turned off, it is automatically activated for a predetermined period of time.

[Problem that the invention seeks to solve]

However, the operation of the intake device A during the above-mentioned work setting was continued by operating the foot switch 18 and continuing to depress the foot switch 18. For this reason, there was a problem in that workers' feet would get tired if they continued to press the foot switch for a long time.

Furthermore, when transferring the work process to the iron press, if the timing of releasing the foot switch 18 and the timing of turning on the iron switch are incorrect, the drive of the intake device A will be temporarily weakened, causing misalignment of the work, etc., and reducing work efficiency. There were also problems that caused it to decline.

This invention was made to solve the above problem, and once the foot switch is turned on, the suction device continues to inhale at the set suction force, and when the iron switch is turned on, the iron suction force changes from the set suction force to the iron suction force over time. The aim is to be able to change it without any gaps.

[Means for solving problems]

This invention provides an ironing board in which a breathable part is supported in an opening of a base body, and outside air can be sucked in from the part by the suction action of an intake device housed in the base facing the opening, and a cloth is set on the ironing board. A setting means for setting the set suction force of the suction device when pressing the cloth set on the ironing board with a steam iron, and a foot switch provided on the operator side of the suction device. Once turned on, the first means continues the intake with the set suction force of the suction device, and after the first means is activated, the iron switch for switching the steam blowing provided on the steam iron is turned on, the suction device is switched on from the set suction force to the iron. The present invention proposes a suction force control device for an ironing board, characterized by comprising a second means for changing the suction force to intake air.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings. FIG. 1 shows an operation panel 15 of the operation box, which is provided on the side of the workpiece 1 at a location where the operator can easily operate it. 8 is a switch for storing or selecting the work conditions described later as a pattern number, 8a is an LED for displaying the pattern number, 9 is a setting switch for memorizing the setting suction force when setting the work, 10 is an iron press 11 is a setting switch that stores the iron suction force at the time of after-vacuum, 9a, 10a,
11a is an LED that displays the memorized suction force corresponding to the setting switches 9, 10, and 11; 12 is a switch for setting the after suction time; 12a is an LED that displays the after suction time; 13, 14
is a switch that allows you to select a numerical value to be set by increasing or decreasing it, and it can also be replaced with a numeric keypad.

Figure 2 is a control block diagram, and the operation panel 1
5 is set, selected and displayed for the CPU 17 via the input/output port 16, and the foot switch 1
8. The iron switch 19 inputs to the CPU 17 the activation of the motor 7 and the progress of the iron press work process, so that the suction force by the air intake device A can be controlled as appropriate. The ROM 20 stores a control program for this device, and the RAM 21 stores suction force, suction time, pattern number, etc. input from the operation panel as operation information of this device.
The CPU 17 connects the output port 22 to the controller 2.
3, and the motor 7 is driven by the driver 24.

Next, the effect will be explained.

In addition to differences in workpiece properties such as area, material, and thickness, there are
There is an optimal suction force and suction time that differ depending on the conditions of the workpiece, including conditions such as changes in the shape of the workpiece during the sewing process, and the work process of the iron press. (See Figure 4). In particular, the suction time is required only when the motor 7 is driven during after-vacuum.

This is stored in the RAM 21 in correspondence with the work process of the first workpiece. That is, after pressing the switch 8, pattern No. 1 is set on the LED 8 using the increase/decrease switches 13 and 14. Then, set suction power, iron suction power, and after suction power are set using switches 9, 10, and 11 and increase/decrease switches 13 and 14, while checking the displays on LEDs 9a, 10a, and 11a to optimize the suction power for the first workpiece. Set the value. Finally, set the suction time T during after-vacuum by pressing switch 12 and using increase/decrease switches 13 and 14.
Configure settings while checking the display on LED12a.

When setting the optimal values of suction force and suction time for a workpiece that has different conditions from the workpiece described above, after setting the workpiece number with switch 8,
The data is stored in the RAM 21 using the same procedure as above.

Next, when performing an iron press operation using this apparatus (FIG. 5), first, the CPU 17 selects a pattern number corresponding to the work to be iron pressed using the switch 8 and the increase/decrease switches 13 and 14. CPU17 has LED9a, 10a, 11a,
12a displays the set suction force, iron suction force, after suction force, and after suction time, respectively.

When the operator places the workpiece on the workpiece and steps on the foot switch 18, the CPU 17 drives the suction device A with a set suction force when setting the workpiece. A suction force that is optimal for setting the workpiece placed on the pad is generated. Once the operator steps on the foot switch 18, the operation of the intake device A is maintained even if the operator takes his or her foot off. Next, the worker holds an iron (not shown) and turns on the iron switch 19 to blow out steam, and the CPU 17 changes the drive of the intake device A from the set suction force to the iron suction force in order to start the iron press. (6th
figure). The perfect suction force for iron pressing is generated on the workpiece placed on the pad, and the workpiece will not curl up or shift. Finally, when the worker turns off the iron switch 19,
The CPU 17 immediately changes the drive of the intake device A from the iron suction force to the after suction force in order to start the after vacuum after the iron press ends.

Furthermore, the CPU 17 sets a timer to start this after-vacuum process and turns on the LED.
After the suction time T shown in 12a has elapsed, the suction device A
automatically stops driving. Moisture contained in the workpiece can be appropriately removed by this aftervacuum, and the workpiece is rapidly cooled and sharp creases are formed, and the suction action is stopped, allowing the operator to remove the workpiece on the part. can be taken up.

When iron pressing workpieces under the same conditions continuously, the above operations are repeated using the foot switch 18 and the iron switch A to instruct the CPU 17 to proceed with the work, and the air intake device A is activated as appropriate.
The suction force and suction time can be controlled in accordance with the progress of the work process, and when iron pressing workpieces with different workpiece conditions, the switches 8, 13, and 14 can be adjusted to suit the workpiece. Work can be executed by calling the pattern number.

In the above embodiment, the suction force and the suction time were determined in a single manner corresponding to one step of the work, but the present invention is not limited to this, and the suction force and suction time can be combined as appropriate.

〔Effect of the invention〕

The structure and operation of this invention are as described above, and once the foot switch is turned on, the suction device continues to draw air with the set suction force, and when the iron switch is turned on, there is a time interval between the set suction force and the iron suction force. Since the suction force can be changed directly without any need for the suction force, the operator is freed from having to keep pressing the foot switch, and there is no need for special operations to change the suction force from the set suction force to the iron suction force. It is now possible to prevent misalignment of the workpiece when changing the force.
