Description

Detailed Description of the Invention The present invention moves the upper trowel from a position above the pad (including when it functions as a lower trowel) to a standby position at the rear by rotating an arm provided with an upper trowel at the tip. The present invention relates to a clothing press that can be opened and closed in the opposite direction.

Generally, in this type of clothing press, the pads on which clothing is attached are provided in a horizontally elongated manner in order to improve operability when pressing various types of clothing.

However, in order to further improve the operability of the garment press, it is desirable to configure the pad to be rotatable in a horizontal plane.

As an example, let's consider pressing and ironing a skirt. First, there are two ways to insert the skirt into the parts: one is to insert it from the belt side of the skirt as shown in Figure 1 A, and the other is to insert the skirt from the belt side as shown in Figure 1. There are two ways to insert it from the hem side, but since skirts usually have a lining, option A is easier to insert.

However, when ironing, you have to use the iron with your right hand while pressing the edge of the hem of the skirt with your left hand to align the pleats of the skirt and maintain that condition. It is easier to iron in this state.

That is, in state A, the left hand holding the hem and the right hand holding the iron intersect, resulting in poor workability.

However, in order to make the garment rotatable in a horizontal plane, special characteristics required of the garment press must be taken into consideration.

Generally, in a clothing press, it is required that the upper trowel presses the garment as perpendicularly as possible to prevent the clothing from wrinkling or twisting.

In conventional clothes presses, the press operation of the upper trowel on the parts is usually performed only by opening and closing the arm, but in this configuration, the upper trowel presses the part of the arm from the beginning to the end of the operation. Since an arc is drawn around the center axis of rotation, it is essentially impossible to press the upper trowel perpendicularly to the part.

This problem itself seems to be solved by bringing the center of rotation of the arm to almost the same height as the pat, but if you do that, the upper trowel will move up and down near the top of the pat. This increases the risk of the worker touching the upper iron.

Furthermore, unless the arm is moved considerably above the part, sufficient space necessary for putting on and taking off clothing cannot be obtained above the part.
While the upper iron is moving and in the standby position, that is, the open position,
The secondary heat from the upper trowel directly hits the worker, making the working environment extremely bad.

Therefore, it is necessary to configure the arm so that the center of rotation of the arm is located below the part so that the upper trowel can move rearward almost horizontally and away from it to a position where there is no danger to the operator.

However, with this configuration, the upper iron is not level with the upper surface of the part even at the press position where it is pressed against the part or immediately before the part is pressed. That is,
First, the outer end of the lower surface of the upper trowel that is closer to the center of rotation will come into contact with the clothing on the part, and then gradually the part of the lower surface of the upper trowel that is further away from the center of rotation will come into contact with it. This causes wrinkles and creases in clothing.

For these reasons, in the conventional configuration in which the press operation is performed only by the rotational movement of the arm,
It is difficult to avoid wrinkles and kinks in clothing.

On the other hand, in order to avoid this, bringing the pivot axis of the arm far back so that the upper trowel can press perpendicularly to the part requires making the arm long, and also This method cannot be used in practice because it requires a large operating space and driving force.

Although not directly aimed at solving this problem, the following idea was published in Utility Model Publication No. 55-34078.

This idea is based on the idea that ``a first arm that is driven by a first cam fixed to a drive shaft is pivotally attached to a proper position of a press body equipped with an ironing board, and a second arm that is attached to a heating element is attached to the first arm. The arm is pivoted at a proper position, the second arm is driven by a second arm fixed to the shaft of the first arm, and the drive shaft and the shaft of the first arm are connected by an appropriate transmission mechanism. Linked with
When the first cam follows a circular arc portion equal to the diameter of the first cam and the rotation stops, the second arm follows the other second cam and the heating attached to the second arm is rotated. It is designed to press the clothes on the ironing board with your body.

However, in this invention, the arm for rotating the heating body (the upper trowel in this specification) is divided into an upper part and a lower part to form a first arm and a second arm. The two cams are rotatably connected (pivotally supported), and furthermore, two cams are attached to each arm, namely, a cam (second) provided on the drive shaft and a cam (second) provided on the shaft of the first arm. 1), the heating element is rotated by acting in two stages, so the structure is extremely complicated, and the pressure of the heating element on the ironing board is applied not in the vertical direction but in an arc. Since the trajectory is drawn, the problem of wrinkles and kinks on clothing has not been fundamentally solved.

SUMMARY OF THE INVENTION An object of the present invention is to provide a press machine having a simple structure and capable of pressing the upper trowel perpendicularly to the part even when the center of rotation of the pressing arm is placed rearward.

To achieve this objective, the present invention is a clothing press in which an upper trowel provided at the tip of an arm approaches a horizontally placed part while drawing an arc from a standby position behind the part to press the part from above. In the machine, the above-mentioned arm is composed of a pressure arm that supports the upper iron and a holding arm that slidably supports the base side of the pressure arm, and the rotating main shaft that rotates the arm has a holding arm. At the same time as fitting the base of the arm, the base of the pressurizing arm functions as a driven joint of the cam fixed to the rotational main shaft, and when pressurizing,
The pressure arm is moved down along the holding arm by the cam rotated by the rotational main shaft, and the upper iron presses the part almost perpendicularly.

Hereinafter, the present invention will be described with reference to an illustrated embodiment.

In FIG. 2, reference numeral 1 in the figure is the main body of the clothes press machine, which consists of a front machine frame 1A and a lower rear machine frame 1B.

A horizontally lying part 3 is rotatably attached to the upper part of the front machine frame 1A via a support column 2, and a shielding plate 1' is provided around the part 3 for the safety of workers. There is.

Next, the reference numeral 4 in the figure is an upper iron that corresponds to the part 3 from above. This upper trowel 4 is arm 5
It is swingably attached to the tip of 0.

The arm 50 includes a horizontal protruding part 5a that supports the upper iron 4 at its tip, a curved part 5b bent downward from the rear end of the horizontal protruding part 5a, and a vertical part extending further downward from the curved part 5b. A pressurizing arm 5 consisting of a base 5c extending from the pressurizing arm 5, and a holding member attached to the base 5c of the pressurizing arm 5 via a connecting portion 7 so as to be able to slide vertically by a relatively fixed distance. It is composed of an arm 6.

In the embodiment, as shown in FIG. 4, the connecting portion 7 includes a U-shaped member 70 fixed to the upper part of the holding arm 6, and a rod 71 provided on the inner surface of the U-shaped member 70 that is pressurized. Horizontal bar 5 provided at the base 5c of the arm 5
1 and 52 are slidably supported.

The lower end side base of this holding arm 6 is connected to the machine frame 1B.
It is fixed to a rotating main shaft 8 provided in the.

Therefore, the arm 50 consisting of the pressure arm 5 and the holding arm 6 can open and close with respect to the part 3 centered on the rotating main shaft 8 located slightly behind the center line of the part 3 by a certain distance. can.

Further, the pressing arm 5 can be moved up and down with respect to the holding arm 6 as will be described later, so that the upper iron 4 can be pressed against the part 3 in the vertical direction, that is, can be pressed.

A shock absorber 9 is provided between the connecting portion 7 of the arm 50 and the machine frame 1B to absorb the shock when the arm 50 opens and closes.

In FIGS. 3 to 5, a rotating main shaft 8 rotatably supported by a machine frame 1B is rotationally driven by an electric motor, a fluid motor, etc. (not shown) via a sprocket 10.

On the rotating main shaft 8, an eccentric cam inner ring 11 as a disc cam is attached to the key 1 at the fixed position of the holding arm 6.
Further, an eccentric cam outer ring 14 is rotatably fitted into the eccentric cam inner ring 11.

Furthermore, a cam stay 15 extending upward is formed on the upper side of this eccentric cam outer ring 14, and the tip of this cam stay 15 is connected to the pressure arm 5.
It is pivotally connected to a shaft 16 provided at the lower end of the base 5c.

Therefore, when the rotating main shaft 8 is rotated, the eccentric cam outer ring 14 that is in sliding contact with the eccentric cam inner ring 11 is vertically displaced, and is connected to the eccentric cam outer ring 14 via the shaft 16 as a driven joint of the cams 11 and 14. The pressing arm 5 moves up and down along the rod 71, that is, the holding arm 6, and the upper iron 4, which is above the part 3, is lowered vertically downward to perform a pressing operation.

Also, if the cam stay 15 of the eccentric cam outer ring 14 is rotated around the eccentric cam inner ring 11, the shaft 16 of the pressurizing arm 5 will be displaced back and forth in the press machine and will move downward. It is also possible to open and close the machine even further in the front and rear directions.

As a means for rotationally displacing the cam stay 15 around the eccentric cam inner ring 11, a toggle joint mechanism 20 operated by a disk 12 fixed to the rotating main shaft 8 is provided.

The toggle joint mechanism 20 has links 21 and 22 connected in a dogleg shape by a shaft 23,
The end of one link 21 is pivotally connected to the shaft 16 of the pressurizing arm 5, and the end of the other link 22 is pivotally connected to a shaft 19 provided at the top of the pole 17.

The pole 17 is erected at the base of the machine frame 1B further behind the rotating main shaft 8.
A shaft 19 for pivoting to the link 22 is supported by a bearing 18 provided at the top of the link 7 .

The height of the shaft 19 for this link pivot is approximately the same height as the shaft 16 of the pressurizing arm 5.

A driven roller 24 for the disk 12 described above is pivotally connected to the central connecting shaft 23 of the links 21 and 22. This driven roller 24 is in contact with the circumferential surface of the disc 12 by a spring (not shown) provided between the lower end of the base of the holding arm 6 and the machine frame 1B.

A driven roller 2 is provided at one location on the circumferential surface of the disc 12.
A notch 25 into which four can be dropped is provided.
The position of this notch 25 is slightly shifted from the position where the eccentric cam outer ring 14 swings upward to its maximum when viewed from the rotation angle position of the rotating main shaft 8.

Therefore, the fifth rotation of the disk 12 by the rotation of the rotation main shaft 8
If it is rotated in the direction of arrow A in the figure, when the shaft 16 and therefore the upper iron 4 reach the uppermost position, the driven roller 24 is still riding on the outer periphery of the disc 12, and the disc 12 is also in the same position. When rotated in this direction, the driven roller 24 falls into this notch 25.

When the driven roller 24 falls into the notch 25, the angle between the links 21 and 22 of the toggle joint mechanism 20 becomes smaller, and the shaft 16 of the pressure arm 5 moves to the lower right in FIG. moves toward the rear of the press, opens, and settles into the so-called standby position (Fig. 6).

At this time, the pressurizing arm 5 moves backward away from the part 3 to the extent that it can rotate the part 3.

Next, the operation will be explained with reference to FIGS. 5 and 6.

Initially, the arm 50 consisting of the pressure arm 5 and the holding arm is in a standby position shown in FIG.

Therefore, as described above, the driven roller 24 of the toggle joint mechanism 20 falls into the notch 25 of the disc 12.

Now, the clothes to be pressed are attached to the part 3, and then the motor is rotated in the normal direction, and the main rotation shaft 8 is rotated for a certain period of time in the direction of arrow B by a first timer (not shown). Immediately after the rotation starts, the driven roller 24 of the toggle joint mechanism 20 opens the notch 25.
The arm 50 is pushed up onto the outer circumferential surface of the disc 12 from above, and the toggle joint mechanism 20 moves the arm 50 toward the main rotation shaft 8.
The upper trowel 4 is positioned above the part 3 in a closed position (upper position).

At this time, the eccentric cam inner ring 11 is in the uppermost rotational position, and the upper iron 4 is positioned directly above the part 3 at an appropriate interval (several centimeters) as described above.

Then, as the rotating main shaft 8 continues to rotate further, the upward eccentricity of the disc cams 11 and 14 becomes smaller, and the pressurizing arm 5 slides downward relative to the holding arm 6. , the upper trowel 4 descends perpendicularly to the part 3 and presses the garment on the part 3.

A first timer (not shown) stops the rotation of the motor at a rotation angle position at which an appropriate pressing force is achieved.
Therefore, the strength of the press can be adjusted as appropriate by the time setting of the first timer.

In this press operation, the upper iron 4 draws a circular arc, although strictly speaking, very slightly, due to the slight circular movement of the link 21 about the shaft 23, so the disc 12 Preferably, it is formed as a correction cam that corrects this error.

After the motor stops, the motor rotates in reverse as an appropriate pressurizing time set by the second timer elapses, causing the rotating main shaft 8 to rotate in the direction of arrow A.

This allows the arm 50 to
While making a slight downward movement due to the action of 4,
The driven roller 24 falls into the notch 25 of the disc 12, that is, it makes a large tilting motion toward the rear about the rotational main shaft 8 together with the holding arm 6.

Therefore, the upper trowel 4 attached to the tip of the arm 50 moves backward substantially horizontally above the part 3 and moves farther backward. When the arm 50 is in the standby position in which it is largely retracted, the part 3 can be rotated 180 degrees if necessary.

When the arm 50 opens wide to the standby position shown in FIG. 6, the motor stops.

FIG. 7 shows an example of the part 3 configured to be rotatable.

This part 3 consists of a flat and elongated part body 30 with chambers 32 and 33 formed on the upper and lower sides of a lower iron plate 31, and a hollow part protruding from a position slightly shifted to one side from the center of the lower surface of the lower iron plate 31. The boss portion 34 is rotatably fitted into the hollow support column 2 fixed to the machine frame 1A.

Inside this hollow support column 2 is an air nozzle 35.
The upper part of the hollow boss part 34 communicates with the upper chamber 32.

On the other hand, the lower chamber 33 has a steam inlet 33.
A is provided, and this lower chamber 33 communicates with a steam outlet 37 through a passage between a cylinder 36 formed around the boss 34 and the boss 34 .

In order to make the rotation of this part 3 smooth, a Teflon ring 38 is provided between the top of the support column 2 and the hollow boss part 34.

Further, reference numeral 39 in the figure is a stopper for regulating the rotation stop position of the part 3, and MS is a micro switch for detecting the position.

As described above, according to the present invention, the pressurizing operation during pressing is not performed by rotating the arm that moves in an arc, but by moving the pressurizing arm that supports the upper iron 4 along the holding arm. This is done by vertically sliding the upper trowel downward, so even if the center of rotation of the arm consisting of the pressure arm and the holding arm is brought to any position behind the part, the upper trowel will not touch the part. Pressure can be applied perpendicularly to the clothes without wrinkles or twisting.

For example, even if the center of rotation of the arm is placed below the part and separated from the part by a wide distance that allows the part to rotate 180 degrees when the arm is closed, the quality of the press finish will be impaired. Never.

Furthermore, when the arm opens, a downward displacement movement is applied due to the action of the disc cam, so the upper trowel attached to the tip of the arm moves away from the part in an almost horizontal direction, causing the operator to Risk of contact is avoided.

Moreover, since the driving force for sliding one pressure arm of the arm relative to the other holding arm is provided by a cam provided on the rotating main shaft, the power required for the press is relatively small. Often, its structure is much simpler, for example, it only requires one cam, compared to the conventional design described above.

Therefore, it is also possible to provide a clothes press with a simple structure and simple operation, which has a low failure rate, low manufacturing costs, and a good press finish.

In the above embodiment, the main shaft is rotated by a motor and the holding arm is opened and closed via a toggle joint mechanism, but it can also be opened and closed by a fluid cylinder or the like.
