Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an ironing board in which the suction action of an air suction device (blower motor) housed in the 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 designates 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 air intake blower 6 is disposed in the central duct 5 of the opening 3, and a blower motor 7 pivotally attached to the blower 6 is housed in the base body. When the foot switch 18 is stepped on, the blower motor 7 is driven so that outside air can be sucked into the base from the part.

This blower motor 7 is normally driven in the following three steps corresponding to the work step of iron pressing a workpiece.

(1) Set suction when setting a workpiece on a part (2) Iron suction when pressing a workpiece with a steam iron (3) After suction when removing moisture from a workpiece by after-vacuum after pressing [The invention [Problems to be Solved] However, the suction force and suction time of the blower motor in each of the above processes are affected not only by differences in properties such as the area, material, and thickness of the workpiece, but also by changes in the shape of the workpiece during the sewing process. There are different optimum values depending on the conditions of the workpiece and the work process of the iron press, and the operator must drive the blower motor to this optimum value when changing workpieces and for each work process of the iron press. It was adjusted to For this reason, the working efficiency of the iron press was reduced, and there were also defects such as poor quality due to adjustment errors.

This invention was made to solve the above-mentioned defects, and the adjustment values of the blower motor are stored in advance for each work condition and iron press work process, and the blower motor is automatically optimized according to the progress of the work process. The purpose is to control the value.

[Means for Solving the Problems] For this reason, the present invention supports a breathable part in an opening of a base, and sucks outside air from the part by the suction action of an intake device housed in the base facing the opening. a setting means for setting an optimal value of at least one of the suction force and the suction time of the suction device in the storage means in accordance with workpiece conditions and a plurality of different work processes of the iron press; A suction device for an ironing board characterized by comprising: a selection means for selecting an optimum value from a storage means in accordance with workpiece conditions and the progress of a work process; and a control means for controlling an intake device according to the selected optimum value. This paper proposes a force control device.

[Example] Hereinafter, an example 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 station 1 so that the operator can easily operate it. 8 is a switch for storing or selecting the conditions of the workpiece as a pattern number; 8a is an LED for displaying the pattern number; 9, 10, and 11 are for controlling the suction force during set suction, iron suction, and after suction. Setting switches 9a, 10a, and 11a are for displaying the memorized values corresponding to setting switches 9, 10, and 11. 12 is a switch for setting the after suction time, and 12a is set by switch 12. The LEDs 13 and 14 that display the set value are switches for selecting the numerical value to be set by increasing or decreasing it, and the numeric keypad is also the same.

FIG. 2 is a block diagram, in which the operation panel 15 makes settings for the CPU 17 via the input/output port 16.
The selection and display are performed, and the activation of the blower motor 7 and the progress of the iron press work process are input to the CPU by the foot switch 18 and the iron switch 19. The ROM 20 stores a control program for the device, and the RAM 21 stores optimal values input from the operation panel as operating information for the device. The CPU 17 operates the driver 23 from the output port 22 to drive the blower motor 7.
Next, the effect will be explained.

Regarding the work you are trying to iron press,
Find the optimal suction force and suction time of the blower motor for each iron press work process (Figure 4). Assume that the suction time is only required when the blower motor is driven by the after suction force.

Next, the optimum value for the work process of the first workpiece is stored in the RAM 21.

That is, after pressing switch 8, increase/decrease switch 1
3 and 14 set pattern No. 1 on LED8. The suction power for set suction, iron suction, and after suction is controlled by switches 9, 10, 11 and increase/decrease switches 13, 14, and LEDs 9a, 10a,
The optimum value for the first workpiece is set while checking the display 11a. Finally, set the optimum value for the suction time T of the after suction by pressing the switch 12 and using the increase/decrease switches 13 and 14 while checking the display on the LED 12a.

To set the optimum value for each work process for another work, select the work No. with switch 8 and do the same as above.
Store it in RAM21.

Next, when performing an iron pressing operation using this apparatus (FIG. 5), first, the pattern number corresponding to the work to be iron pressed is selected using the switch 8 and the increase/decrease switches 13 and 14. and,
Spread this work on part 1 and turn on foot switch 18.

The CPU 17 displays the suction force at the time of set suction stored in the RAM 21 on the LED 9a, and drives the blower motor with this suction force. When the workpiece is placed on the spot, suction force is generated that is optimal for setting the workpiece. Once the foot switch 18 is pressed, the motor 7 continues to be driven even if the foot is removed. Next, the worker holds an iron (not shown) and
When the iron switch 19 is turned on to emit steam, the CPU 17 displays the suction force for iron suction stored in the RAM 21 on the LED 10a, and drives the blower motor 7 with this suction force. Workpieces placed on the pad generate suction power that is ideal for iron pressing. Finally, when the worker turns OFF the iron switch 19 to end the iron press, the CPU 17 displays the suction force at the time of after suction stored in the RAM 21 on the LED 11a, and also controls the blower motor 7 according to this suction force, which is displayed on the LED 12a. Suction time driven,
The optimum suction force and suction time to remove moisture contained in the workpiece are generated, and after this time elapses, the drive of the blower motor 7 is automatically stopped. As a result, the workpiece is rapidly cooled and sharp creases are formed, allowing the operator to pick up the workpiece on the part.

When iron-pressing workpieces under the same conditions continuously, by repeating the above operations using the foot switch 18 and ironing switch 19, you can instruct the CPU to proceed with the work process and execute it. In the case of iron pressing, the work can be started by calling up the pattern number corresponding to the work using the switches 8, 13, and 14.

In addition, in the above-mentioned embodiment, in one step of the work, the optimum value of the suction force and the suction time was determined separately, but the present invention is not limited to this, and it is possible to combine the suction force and suction time as appropriate.

[Effects of the Invention] The structure and operation of the present invention are as described above, and the suction force and suction time, which are different depending on the conditions of the workpiece and the work process of the iron press, are set and memorized, and the blower motor is adjusted in accordance with the progress of the work process. can be automatically controlled to the optimum value, which eliminates the hassle of setting appropriately for each work condition and iron press work process, which improves work efficiency and eliminates adjustment errors. This can prevent quality defects in the iron press.
