Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a small automatic iron press machine.

Conventional automatic iron press machines were large and were used for rotary work. The heater was also large, at 10 to 20kw, and the entire fabric had to be heated in order to line one part of the fabric, which caused problems such as shrinkage of the fabric.

The present invention aims to provide an automatic iron press machine which is similar to the conventional small iron press machine for single-sheet ironing, but which is an automatic type unlike the conventional manual type, and which can be formed compactly using a link mechanism. It is something.

The present invention will be described below with reference to the embodiments shown in the drawings. FIG. 1 shows a perspective view, FIG. 2 shows a side view, and 1
2 is a lower ironing board; 2 is an upper ironing board; both have a built-in heater (not shown); a heater cord 3 is connected to the heater; an electric control box 4 is provided at the bottom of the lower ironing board 1;
A temperature setting dial (with thermostat) 5 is provided on the top surface of the upper ironing board 2, and although not shown, these boxes 4 and dial 5
is connected to the heater of the ironing board through an electric circuit.

The lower ironing board 1 is fixed to the upper part of the frame 6, and the upper ironing board 2 is attached to the clamp arm 7.
It is pivotally connected to the upper end of the body by a shaft 8, and is of a swing type. The lower part of the clamp arm 7 is pivotally connected to a bracket 10 fixed to the frame 6 via a shaft 9, and the tip of a rod 11 is connected to a shaft 12 pivotally attached to the lower end. The base of the rod 11 is connected to a crank disk 1 fixed to a shaft 14 supported by a bearing 13 on the frame 6.
It is pivotally connected to the eccentric pin 16 of No. 5. The shaft 14 is driven by a geared motor 17 via a chain 18 and sprockets 19 and 20.

21 and 22 are located around the crank disk 15.
The first and second micro switches are attached to the frame 6 with a phase shift of 180 degrees, and are opened when they engage with protrusions 23 attached to the outer periphery of the crank disk 15, respectively, as shown in FIG. When the protrusion 23 engages with the first micro switch 21, the lower end of the clamp arm 7 is pulled by the rod 11 and rotates clockwise about the shaft 9, so that the upper ironing board 2 and the lower ironing board 1
The motor 17 is stopped.

Further, when the convex portion 23 engages with the second micro switch 22, the upper ironing board 2 is connected to the ironing board 1.
At this time, the second micro switch 22 is opened and the motor 17 is stopped, and after a predetermined period of time, the motor 17 is driven again. Reference numeral 24 denotes a spring interposed between the shaft 12 and a nut 25 screwed onto the threaded portion 11a of the rod 11, so that the shaft 12, that is, the shaft 9
The clamp arm 7 is urged counterclockwise using the fulcrum as a fulcrum. Further, the upper ironing board 2 is pivotally supported on a shaft 8 via a bracket 26 so as to be swingable as shown by the arrow in FIG. 27 is a push button switch that starts the motor 17 for starting, and the code 28
and is connected to the electrical control box 4.

Now, the circuit 30 for controlling the drive of the motor 17 will be explained with reference to FIG. ing. 32 is a relay, 32a
is a contact of relay 32, 33 is a timer, and 33a
is a contact point of the timer 33. Relay 32 is connected in parallel to motor 17, timer contact 33a is interposed between power supply 31 and relay 32, and relay contact 32a, timer 33, and power supply 31 are connected in series. Therefore, when the relay 32 is energized, the timer contact 33a is open, and when the relay 32 is de-energized, the timer contact 33a is open.
The timer contact 33a is designed to close.
Further, when the timer 33 is de-energized, the timer contact 33a is open, but when the timer 33 starts being energized and a predetermined time elapses, the timer contact 33a closes.

Next, to explain the operation, as shown in Fig. 2, the first micro switch 21 comes into contact with the protrusion 23 of the crank disk 15, the upper ironing board 2 is lifted away from the lower ironing board 1, and the motor 17 is stopped. Then, the article to be pressed 29 is set on the lower ironing board 1, and the pressing operation is started.

The work is started by pressing the push button switch 27, and the motor 17 starts driving. At this time, the relay 32 is energized, so the relay contact 32a
is opened, the timer 33 is not energized, and the timer contact 33a remains open. When the motor 17 is driven, the shaft 14 rotates via the sprocket 19, chain 18, and sprocket 20, and the crank disk 15 begins to rotate counterclockwise in FIG. Accordingly, the eccentric pin 16 also rotates counterclockwise, and the shaft 12 begins to be gradually pushed up from the lowest position through the rod 11 shown in FIG. and eventually the protrusion 23 becomes the second
When it comes into contact with the micro switch 22, the micro switch 22 opens and the drive of the motor 17 is stopped. At this point, the upper ironing board 2 descends and comes into contact with the lower ironing board 1, and from this time on, the pressed product 29 is pressed for a predetermined period of time by holding the clamping force of both ironing boards by the spring 24.
Therefore, when the second micro switch 22 is opened,
Since the relay 32 is de-energized, the relay contact 32a is closed and the timer 33 is started to be energized. Then, when a predetermined period of time has elapsed, the timer contact 33a closes and the motor 17 is driven again. At the same time, the relay 32 is energized and the relay contact 32a is opened, and the timer 33 is cut off and the timer contact 33a is opened. Motor 1
7 starts driving again, the crank disc 15
is a protrusion 23 from the position of the second micro switch 22.
The rod 11 rotates half a turn until it comes into contact with the first micro switch 21, and this contact opens the first micro switch 21, and at the same time the rod 11
6 rotates to the position shown in Figure 2, the shaft 12
The clamp arm 7 rotates clockwise about the shaft 9 via the ironing board 1, and the upper ironing board 2 moves upward away from the lower ironing board 1.

The present invention is constructed as described in detail above, and the upper ironing board is pivotally connected to the clamp arm in a swing-like manner, so that the clamp arm rotates counterclockwise via the rod by the rotation of the crank disk. When the upper ironing board is rotated using the ironing part as a fulcrum, the upper ironing board can come into contact with the lower ironing board horizontally, and the clamping force at this time is maintained by the spring attached to the rod, and the press setting time by the timer is sufficient. It is possible to press set items to be pressed.

In addition, in the present invention, the motor is driven by simply pressing the start switch at startup, the drive of the motor is stopped by the second switch, and after the upper and lower ironing boards are brought into contact and the press setting is performed for a predetermined time by the timer, the motor is started. The series of operations from re-driving the upper and lower ironing boards to finishing setting and stopping the motor drive by the first switch is performed automatically, and the structure is simple as the mechanism is a link mechanism using a clamp arm. Therefore, the entire structure can be extremely compact, and it is extremely convenient to incorporate it into an automatic sewing system.
