Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a three-dimensional pressing device for clothing sleeves, and more specifically, to an inner iron that is located inside the sleeve and expands the clothing sleeve during pressing.

(Problems with the Prior Art) This type of inner iron consists of two expansion plates for each sleeve, one of which is located on the elbow side of the arm and the other on the bent side of the arm. Each extends along the length of the arm.

The expansion plate is gently curved in the length direction and rounded in the direction around the arm in the width direction so as to correspond to the shape of the sleeve when worn naturally.

This pair of expansion plates work together to expand and shape the sleeve from the inside, and the shoulder side links and the cuff sides are linked together, and the shoulder side link and the cuff side link are connected. It has a different air cylinder as a driving source. The piston rod of the shoulder side air cylinder is connected to the shoulder side link, and the piston rod of the cuff side air cylinder is connected to the cuff side link.

These two air cylinders are connected in parallel to one air circuit in order to operate them simultaneously and to simplify the drive circuit.

Therefore, the ratio of the momentum of the two air cylinders, that is, the degree of expansion between the shoulder side and the cuff side of the expansion plate is constant, and the expansion of the shoulder side and the cuff side is performed at the same time, and the degree of expansion is constant. will be the same.

By the way, when pressing the sleeves of clothes, ideally the cuff side should be flat so that they are parallel to the body side, and the shoulder side should be rounded and plump in the direction around the arm.

Sleeves for suits and other clothing are thicker than shirts, etc., so relatively strong expansion pressure is required on the cuff side to create a flat finish, but on the shoulder side, it is sufficient to simply shape the sleeve into a cylindrical shape. Therefore, the expansion pressure may be weak. If the expansion pressure on the shoulder side is strong, there is a risk that the shape will collapse.

There is generally not much difference in the size of the cuff side of clothes, and there is no problem as long as strong expansion pressure is applied to the cuff side, but the size of the shoulder side varies greatly depending on the design of the clothes, and there is a wide range of variations. It is. Therefore, depending on the size of the shoulder side, conventional three-dimensional presses cannot be used.

The object of the present invention is to provide a three-dimensional press device for clothes sleeves that can adjust the degree of expansion of the inner trowel according to the shoulder size.

(Structure of the invention) The present invention comprises a pair of expansion plates serving as inner trowels, which are two expansion plates that expand the sleeve from the inside, and the shoulder sides and the cuff sides of both expansion plates are linked and connected, respectively. A shoulder-side air cylinder that drives the shoulder-side link, a cuff-side air cylinder that drives the cuff-side link, an air circuit in which the shoulder-side air cylinder and the cuff-side air cylinder are connected in parallel, and the shoulder-side air cylinder. It consists of an adjustable regulator installed in the air circuit conduit to the expansion pressure chamber, and the regulator keeps the expansion pressure on the shoulder side constant so that it does not exceed an arbitrary value, and when pressurizing. In this method, air is supplied to the shoulder side air cylinder and the cuff side air cylinder at the same time to simultaneously expand the shoulder side and cuff side of the pair of expansion plates, and the shoulder side is expanded regardless of the degree of expansion on the cuff side. By keeping the expansion pressure constant, the degree of expansion of the inner trowel between the cuff side and the shoulder side can be adjusted in accordance with the form of the sleeve.

(Example) Hereinafter, the present invention will be explained based on drawings showing an example of implementation.

Figures 1 and 2 show a sleeve mold for the right sleeve, and 10 is an inner trowel.

The inner iron 10 is used to expand and shape the sleeves of clothes from the inside, and includes an expansion plate 10A that is located on the elbow side of the arm and extends in the length direction of the sleeve, and an expansion plate 10A that is located on the bending side of the arm and extends in the length direction of the sleeve. Expansion plate 10B extending in the length direction of the sleeve
It consists of

The pair of expansion plates 10A and 10B are designed to cooperate with each other to cause expansion.
The shoulder sides of A and 10B and the cuff sides are 2 each.
Book link rods 11A, 11B and 12A, 12B
It is connected with.

A piston rod 11 of a shoulder side air cylinder 111, which serves as a driving source for expanding the shoulder side, is installed at the connecting portion between the shoulder side link rod 11A and the link rod 11B.
1A, and the protruding ends of piston rods 112A of the cuff-side air cylinder 112, which serves as a driving source for the cuff-side expansion action, are connected to the connection points between the cuff-side link rods 12A and 12B, respectively. It is tied.

Each of the above link rods 11A, 11B, 12A, 1
2B are pivotally connected to the base plate 13 at their intermediate portions in the longitudinal direction, so that the distance between the pair of expansion plates 10A and 10B expands or contracts in accordance with the reciprocating movement of the piston rods 111A and 112A. It has been placed.

In the embodiment, piston rods 111A, 112
When A protrudes from the air cylinders 111, 112, it expands, and when it retreats, it contracts.

Further, the shoulder-side air cylinder 111 and the cuff-side air cylinder 112 are each fixed to the base plate 13 described above.

The above-mentioned sleeve mold is covered with an air bag (not shown), and air or steam is supplied or discharged through a supply/discharge hole 14 formed in the substrate 13. The sleeves of the garment are also pressed by the inflation pressure of the air bag.

Incidentally, reference numeral 15 shown in FIG. 2 is a lid body that covers the substrate 13. Further, FIG. 3 shows a three-dimensional pressing device for clothes sleeves, which is equipped with a pair of sleeve molds.

Next, the air circuit shown in FIG. 1 will be explained.

For convenience of explanation, of the two pressure chambers partitioned by pistons in the shoulder-side air cylinder 111 and the cuff-side air cylinder 112, the one without the piston rod will be referred to as the "expansion pressure chamber 111".
B" and "expansion pressure chamber 112B," and the one with the piston rod is called "reduction pressure chamber 111C," respectively.
It is called "reduction pressure chamber 112C."

Reference numeral 21 in the figure is a four-way valve for switching the flow path from the air source 20. The four-way valve 2
1, one of the three channels is an outlet 21A to the outside, and one of the remaining channels is connected to the shoulder side air cylinder 1 through a pipe 22 branched in the middle.
The expansion pressure chamber 111B of No. 11 and the expansion pressure chamber 112B of the cuff side air cylinder 112 are connected in parallel, and the other is connected to the contraction pressure chamber 111C of the shoulder side air cylinder 111 and the cuff side air cylinder through a conduit 23. It is connected in parallel to the expansion pressure chamber 112C of No. 112.

Reference numeral 24 denotes a regulator, which is provided in the branch path 22A of the conduit 22 leading to the expansion pressure chamber 111B in order to adjust the pressure of the shoulder side air cylinder 111 to the expansion pressure chamber 111B.

In addition, in the figure, the reference numeral 25 on the upstream side of the four-way valve 21
2 is a regulator for setting the source pressure, and 26 is an air filter. Further, reference numeral 27 is a foot pedal for operating the four-way valve 21,
The flow path can be switched by pressing the pedal.

Next, the operation will be explained.

First of all, the device needs to be attached to the sleeve shape of the clothes,
The inner iron 10 is in a contracted state, that is, the piston rods 111A and 112A are in a retreated state into the cylinder.

In this case, the source pressures 111 and 112 are the reduction pressure chambers 111C and 111C of the air cylinders 111 and 112, respectively.
112C, expansion pressure chambers 111B, 11
2B is opened to the outside via a four-way valve 21.

Clothes sleeves are worn under such reduced conditions.

Next, the foot pedal 27 is depressed to switch the flow path, supplying air to the expansion pressure chambers 111B and 112B, and communicating the contraction pressure chambers 111C and 112C with the outside.

By supplying air to the expansion pressure chambers 111B, 112B, the piston rods 111A, 112A protrude, and the inner iron 10 expands.

At this time, by adjusting the regulator 24 interposed in the branch passage 22A leading to the expansion pressure chamber 111B of the shoulder side air cylinder 111 in advance to match the size of the clothes sleeve to be worn, the shoulder side air Expansion pressure chamber 111B of cylinder 111
The internal pressure, that is, the expansion pressure on the shoulder side can be kept constant so as not to exceed an arbitrary value.

As a result, even if air is supplied to the shoulder side air cylinder and the cuff side air cylinder at the same time during pressurization to simultaneously expand the shoulder side and cuff side of the pair of expansion plates, the cuff side will not expand. Regardless of the degree of expansion, the expansion pressure on the shoulder side remains constant, so one pressurization operation (air supply operation) can adjust the degree of expansion of the cuff side and shoulder side of the inner iron to match the shape of the sleeve. The desired press finish can be achieved according to the size of the shoulder side. For example, it can be made smaller than the pressure (original pressure) of the expansion pressure chambers 111B and 112B of the cuff side air cylinder 112.

In this finishing process, appropriate air or steam is sent through the supply and exhaust holes of the substrate 13 to inflate the air bag.

Finally, when finishing is completed, the foot pedal 27 is depressed again to switch the flow path of the four-way valve 21. That is, the source pressure is applied to the contraction pressure chambers 111C, 112C of the air cylinders 111, 112, respectively, and the expansion pressure chambers 111B, 112B are opened to the outside.

As a result, the piston rods 111A, 112
A retreats into the cylinder, and the inner iron 10 contracts and returns to its original contracted state. After he has fully recovered, the sleeves of his clothes are removed. This completes the pressing operation.

(Effects of the invention) The present invention consists of a pair of expansion plates that expand the sleeve from the inside, and a pair of expansion plates as an inner trowel in which the shoulder sides and the cuff sides of both expansion plates are linked and connected, respectively; A shoulder-side air cylinder that drives the shoulder-side link, a cuff-side air cylinder that drives the cuff-side link, an air circuit in which the shoulder-side air cylinder and the cuff-side air cylinder are connected in parallel, and the shoulder-side air cylinder. Since it is equipped with an adjustable regulator installed in the air circuit conduit to the expansion pressure chamber, the regulator 24 can be adjusted in advance to match the size of the sleeve of the clothes to be worn. Then,
The expansion pressure on the shoulder side by the shoulder side air cylinder can be kept constant so as not to exceed an arbitrary value.

Therefore, even if air is simultaneously supplied to the shoulder-side air cylinder and the cuff-side air cylinder during pressurization to simultaneously expand the shoulder-side and cuff-side of the pair of expansion plates, the expansion of the cuff-side will not occur. Regardless of the degree, the expansion pressure on the shoulder side remains constant, so one pressurization operation (air supply operation) can adjust the degree of expansion of the cuff side and shoulder side of the inner iron to match the shape of the sleeve. The desired press finish can be achieved according to the size of the shoulder side.

Therefore, the present device can be used to press finish more garments with different types and shapes of sleeves than conventional devices.
