Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a trowel pressurizing device for a clothes press.

(Prior Art) Various structures have been proposed for this type of pressurizing device.

For example, the invention proposed in Japanese Unexamined Patent Publication No. 56-132998 relates to a clothing press in which a doll body located at the center is compressed by a pair of trowels disposed on both sides of the doll body. The pair of trowels has a structure in which the upper ends of the trowels largely expand and close, similar to the opening of a tulip flower, with the bases of each trowel being the center of rotation.

The pair of irons are driven by a single driving source.
simultaneously and through a complex interconnected linkage.
They are connected to operate in a series of circular arcs, opening and closing like a flower opening and closing.

However, in the iron pressing device having the structure of the present invention, the pressing step, more specifically, the operation of bringing the iron closer to the doll's body, and the pressing operation of the final stage of applying the iron to the clothing, Since this is performed using a single cylinder, it is extremely difficult to set the timing for the final pressurization operation.

The final pressurizing operation is different from a simple rotation of the iron arm, and must press the clothing firmly with a much stronger force.

If this timing is off, that is, if it is too early or too late, the final stage of pressurization will be insufficient, making it impossible to obtain a good finish.

Further, the present invention provides, through a large number of link members,
Since the structure is such that the transmission is transmitted to a pair of irons, an unreasonable load is applied to the pivot joint where the link member is connected, causing premature wear of the pivot joint, which tends to cause so-called "backlash". As a result, there is a difference in the timing of the pressurizing operation in the final stage, and
The "backlash" causes the iron to shake, causing wrinkles in clothing.

The present invention was made with the aim of solving this problem.

(Means for Solving Problems) The iron pressurizing device of the present invention has a soldering iron 13 in the upper part which is pressed against the doll body 11, and a base 20A on the frame.
A soldering iron arm 20 to which the iron arm 20 is rotatably attached, and a driving cylinder 2 for rotating the iron arm 20.
2, a positioning link means 21 interposed between the soldering iron arm 20 and the frame so that the soldering iron 13 is stopped at a position in close proximity to the doll body 11 at a certain distance; Means 21 and the iron arm 20
a cam means 31 that is located at a pivot portion of the iron arm 20 and acts on the iron arm 20 with the pivot as a rotational center axis; The pressure cylinder 40 presses the iron 13 against the doll body 11, and the pressure cylinder 40 presses the base 2 of the iron arm 20 when the iron 13 is in the close position.
The iron arm 2 is located at a position where its center of gravity is on the doll body 11 side from the perpendicular line passing through the pivot point to the frame of 0A.
It is characterized in that it is supported on the zero site.

(Operation of the invention) During the pressurizing process, when the iron arm is rotated and the iron approaches the doll body, the positioning link means causes the iron to be spaced a little apart from the doll body. It is temporarily stopped at a close position.

Thereafter, the pressurizing cylinder operates the cam means to further rotate the iron arm by a length corresponding to the eccentricity of the cam, and the iron is brought into pressure contact with the doll body from a position close to the doll body. A stepwise pressurization operation is performed.

Moreover, during this pressurization, the pressurizing force of the iron is not only the pressure of the pressurizing cylinder, but also the load of the pressurizing cylinder itself.

(Example) The present invention will be described below based on an example of a rotary clothing press.

As shown in Figure 1, the rotary clothing press machine is
A pair of doll trunks 11, 11 set for one press device 10 is provided on a rotating body 12, and by repeatedly rotating the rotating body 1 180 degrees, the doll trunks 11, 11 are alternately pressed. It is configured to be set in the apparatus 10 and pressed.

The press device 10 includes a pair of irons 1 facing each other.
The doll body 11, 11 is alternately received and pressed between the trowels 13, 13.

The soldering iron 13 is pressed against the doll body 11, and is mounted on the upper part of a soldering iron arm 20 whose base portion 20A is rotatably pivoted to the frame.

In addition, the reference numeral 14 in the figure is a rotational shaft of the rotating body 12, and the reference numeral 15 is a rotational drive device for the rotational shaft.

The press apparatus 10 will be explained with reference to FIGS. 2 to 6.

FIG. 2 shows that the iron arm 20 is rotated by the drive cylinder 22 during the pressurization process.
The soldering iron 13 is close to the doll body 11, and the soldering iron 13 is stopped at a position in close proximity to the doll body 11 with a slight distance therebetween, and is in a state just before applying pressure, i.e. , shows the state just before the final stage of the pressurizing operation. Hereinafter, this state will be referred to as a "state immediately before pressurization."

The above-mentioned stopped state is maintained by a positioning link means 21, which will be described later, which is interposed between the iron arm 20 and the frame.

Reference numeral 20 in the figure is a soldering iron arm that supports the soldering iron 13, and its base 20A is pivotally attached to the frame (not shown) of the press 10.

In the state immediately before applying pressure, the positioning link means 21 whose ends are connected between the waist of the soldering iron arm 20 and the frame, and the constituent members of the positioning link means 21 are activated to operate the positioning link means 21. A drive cylinder 2 to which a piston rod 23 is connected
Supported by collaboration with 2.

Note that the base of the drive cylinder 22 is pivotally attached to a frame (not shown) of the press 10.

The above-mentioned positioning link means 21 is constructed by connecting two connecting rods in a straight line, and the piston rod 23 of the drive cylinder 22 is connected to the connecting point 21P of the connecting rods. Therefore, the positioning link means 21, depending on the movement of the piston rod 23,
The iron arm 20 is rotated by extending in a straight line or bending in an inverted "he" shape.

In the state immediately before pressurization, the positioning link means 21 is fixedly maintained in an extended state by the drive cylinder 22.

In this case, in order to ensure that the state immediately before pressurization is maintained, in the embodiment, the stopper 24 is moved near the positioning link means 21 so that the positioning link means 21 receiving the pressure of the piston rod 23 remains in a straight line state. provided in the stopper 24 and the piston rod 23.
The positioning link means 21 is configured to be fixed.

The reference numeral 31 in the figure is a cam means, and the cam means 3
Reference numeral 1 is located at a pivot between the positioning link means 21 and the iron arm 20, and is configured to act on the iron arm 20 using the pivot as a rotation center axis.
This will be explained with reference to FIGS. 3 to 5.

First, the cam means 31, as shown in FIG.
It has a main shaft 32 and an arm 33 extending from the main shaft 32 in a direction perpendicular to the axis.

Blind hole-shaped bearing holes 34 are bored in both end faces of the main shaft 32 in a direction parallel to the axis of the main shaft 32, and the axes of the two bearing holes 34 and the bearing hole 34 are aligned.

However, both bearing holes 34, 34 are bored such that their axes are offset from the shaft center line of the main shaft 32 by a certain distance (α in the figure), as shown in FIG.

Arm pressurizing shafts 36, 36 described below are fitted into the bearing holes 34, 34.

As shown in FIG. 5, this cam means 31 is arranged between arm constituent members 35, 35 extending in parallel, and the left and right arm constituent members 35, 35
An arm pressurizing shaft 36, which is inserted into the bearing holes 34, 34 of the cam means 31, respectively, from the outer surface side thereof.
It is supported by 36.

The main shaft 32 of the cam means 31 is fitted with a bearing 21B formed at one end of the connecting rod 21A of the positioning link means 21.

When assembling the cam means 31, first, the positioning link means 21 is assembled, contrary to the order described above.
After fitting the main shaft 32 of the cam means 31 into the bearing 21B of
6 and 36 and assemble.

In addition, the reference numeral 37 in the figure indicates a slide ring interposed between the end surface of the main shaft 32 and the arm component 35, and the reference numeral 38 indicates a bearing 21 of the positioning link means 21.
This is a ring spacer to keep the position of B constant.

As can be seen from FIG. 2, the drive source for the cam means 31 is a pressurizing cylinder 40 pivotably mounted on the iron arm 20, and its piston rod 41 is connected to the arm 33 of the cam means 31.

Therefore, the pressure cylinder 40 is rotated together with the iron arm 20 supporting it.

This pressurizing cylinder 40 operates the cam means 31 when the iron arm 20 rotates and the iron 13 comes to the above-mentioned close position with respect to the doll body 11.
The soldering iron 13 is brought into pressure contact with the doll body 11 by further rotating the soldering iron arm 20 from the close position.

Further, this pressurizing cylinder 40 is located at a portion of the iron arm 20 at a position where the center of gravity is on the doll body 11 side from a perpendicular passing through the pivot point of the base 20A of the iron arm 20 to the frame when the iron 13 is in the close position. It is carried by

In the embodiment, the rear end side of the pressure cylinder 40 is swingably suspended from the upper part of the iron arm 20.

By attaching the pressure cylinder 40 to such a part of the iron arm 20, during the final stage of pressurization, the iron arm 2 is not only affected by the pressure of the pressure cylinder 40 but also by the load of the pressure cylinder 40 itself.
The rotational moment toward the doll body side of 0 can also be used as the pressing force.

Next, the pressurizing operation of the iron 13 is shown in FIG. 1, which shows the standby state of the iron 13 with broken lines, FIG. 2, which shows the state immediately before applying pressure, and FIG.
This will be explained using figures.

The movement of the iron 13 from the standby state shown in FIG. 1 to the state just before pressurization shown by the solid line is performed by using the drive cylinder 22 and extending the positioning link means 21 from the bent state to the straight state.

The length of the positioning link means 21 when the positioning link means 21 is in a straight line state is set in advance to a length at which the iron 1 stops at a position close to the doll body 11.

When the positioning link means 21 is in a state immediately before pressurization, it is held between the pressure of the drive cylinder 22 (piston rod 23) and a stopper 24 arranged to resist the pressure, and its linear state is forcibly maintained. will be maintained.

Further, when the cam means 31 reaches the state immediately before applying pressure, as shown in FIG.
The axial center of the main shaft 32 of the cam means 31 is set in advance so that it is located on a perpendicular line passing through the axial center of the main shaft 32 of the cam means 31.

The final stage of pressurization is performed under the conditions immediately before such pressurization.
The pressurizing cylinder 40 is activated, and the arm pressurizing shaft 3
The main shaft 32 is rotated 90 degrees so that the positioning links 6 and 36 are located on the extension line of the positioning link means 21.

As a result, the iron 20 is rotated about its base 20A until the arm pressurizing shafts 36, 36 reach the position shown in FIG. 6 from the position shown in FIG. Then arm pressure shaft 3
Distance α between the axis center of 6, 36 and the axis center of the main shaft 31
Move forward further by a length corresponding to
Pressurized to 1.

During this pressurization, the iron arm 20
0A and the frame-side pivot portion of the positioning link means 21 serve as its fulcrum.

After pressurization, the iron 13 is once returned to the state immediately before pressurization by the pressurizing cylinder 40, and then retreated to the standby position.

Then, when the iron 13 retreats to the standby position, the doll trunk 11 is separated from the iron device 10 by the rotation of the rotating body 12, and the other doll trunk 11, on which clothing has already been set, is replaced by the iron device 10. .

As shown in the above embodiment, the iron pressurizing device 30 includes:
It consists of a soldering iron arm 20, a drive cylinder 22, a positioning link means 21, a cam means 31, and a pressure cylinder 40.

In the above embodiment, the present invention is applied to a rotary clothes press, but the present invention is not limited to this and can be applied to clothes presses in general.

(Effect of the invention) According to the invention, in the pressurization process,
When the trowel arm is rotated and the trowel approaches the doll's body, the positioning link means causes the trowel to be temporarily stopped at a position in close proximity to the doll's body with a slight distance between the trowel and the doll's body. When the pressure cylinder operates the cam means, the iron arm is further rotated by a length corresponding to the eccentricity of the cam, and the iron is brought into pressure contact with the doll's body from a close position, and the final stage of pressurization is performed. Because the operation is performed, compared to the conventional configuration in which the operation of bringing the iron closer to the doll's body and the final pressurizing operation of applying the iron to the clothing are performed by a single cylinder, the final pressurizing operation is faster. It is possible to reliably set the timing at which the event occurs.

Therefore, it is possible to eliminate insufficient pressure and the occurrence of wrinkles due to timing discrepancies, and it is possible to obtain a good finish.

Furthermore, since the present invention has a simpler mechanism than conventional pressurizing devices, it is possible to provide a highly durable device that is less prone to looseness due to wear of pivot parts, etc., and has fewer failures.

Therefore, manufacturing, assembly work, maintenance and inspection work, etc. can be performed extremely easily.

Furthermore, according to the present invention, during the final stage of pressurization, the pressurizing force of the iron is not only the pressure of the pressurizing cylinder, but also the load of the pressurizing cylinder itself, so the pressurizing force is increased accordingly. It is efficient as it can reduce the burden on the cylinder.
