Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a shirt press machine for pressing and finishing shirts such as dress shirts and work clothes.

[Conventional technology]

Conventional shirt press machines are equipped with air bags on both sides of the torso that can be expanded and deflated to accommodate changes in the size of the shirt. The front and rear surfaces are crimped with a pair of hot plates for a press finish. In such pressing operations, if the hot plate is pressed with the front section of the shirt wide open due to the expansion of the air bladder, the shirt will be molded in a collapsed state, resulting in an extremely poor finish. For this reason, conventional jacket stands are equipped with a front presser that fixes the lower part of the front body of the shirt to prevent it from opening too much.

[Problem that the invention seeks to solve]

This type of front presser usually has a T-shaped plate spring whose lower end is fixed to the lower part of the body stand. With this, the upper end of the front presser uses its own elasticity to press against the torso to secure the front body of the shirt. However, with this structure, when putting the shirt over the torso stand, it is necessary to remove the front presser from the torso stand by hand and then sandwich the lower part of the front body of the shirt between the torso stand and the front presser. There is a problem that requires a lot of effort.

For this reason, Japanese Utility Model Publication No. 7679/1983 proposes a mechanism in which the front presser is moved mechanically.

As shown in FIGS. 9 and 10, this is a rotating block 23 in which a T-shaped spring front presser 21 is attached to the front lower end of a torso stand 22 so as to be slidable in the front-rear direction.
It is fixed to the upper part and the rotating block 23 is swung by the action of a horizontal air cylinder 24 and a cam mechanism 25.The front presser can be crimped onto the body by driving the air cylinder 24. , which is superior to manual methods in that it is easier to work with.

However, in all of the above conventional structures, the front presser simply presses the front body of the shirt, so when the hot plate is next crimped, the wrinkles on the front body surface are not stretched out. It may be pressed. As described above, if the front body is not fixed in a wrinkled state, when the air bladder is inflated, the shirt will not be inflated to the correct shape, and wrinkles will remain on the surface of the finished shirt. For this reason, conventionally, when crimping a hot plate, the worker had to pull the bottom edge of the shirt downward to smooth out the wrinkles on the surface of the shirt, which required extra work and caused the front presser to become hot. There is a problem with the risk of burns due to contact with the equipment.

Also, when crimping the hot plate, the front presser does not move and remains pressed against the shirt, so it is pressed at the same time as the hot plate is crimped, and the crimping marks are left on the shirt, resulting in a uniform finish. There is also the problem of not being able to

The present invention was made with the aim of solving the above-mentioned problems with the conventional front presser.

[Means for solving problems]

In order to solve the above problem, this invention has a vertically movable sliding plate attached to the front lower end of the torso stand, and a swinging block fixed to the lower end of the front holding device. A cylinder device is installed to be slidable in the front-rear direction and extend and contract in the left-right direction of the torso, and a cam plate connected to the cylinder device is provided with a cylinder that is inclined vertically in the same direction as the direction of expansion and contraction of the cylinder device. A first cam surface and a second cam surface are provided on the front surface of the swing block, and engage with the first cam surface to swing the swing block back and forth in accordance with the expansion and contraction movement of the cylinder device. In addition to installing a movable roller, a fixed roller is installed on the barrel stand, which engages with the second cam surface and moves the sliding plate between the vertical movement strokes as the cylinder device expands and contracts; A cylinder that engages both cam surfaces and both rollers at an engagement position between the second cam surface and the fixed roller relative to an engagement position with the movable roller when the front presser is pressed against the barrel stand on the cam surface. The device is positioned rearward in the moving direction of the device, and the front presser is at a position opposite to the lower part of the front body of the shirt when the sliding plate is at the upper position of the moving stroke, and when the front presser is at the lower position of the moving stroke. The structure is such that it is located below the crimping range by the hot plate.

[Effect]

In the shirt press machine configured as described above, when the cylinder device is driven in the direction in which both rollers and both cam surfaces engage after a shirt is placed on the barrel stand, first the first cam surface and the movable roller engage. Then, the front presser is crimped onto the bodice, fixing the front section of the shirt to the bodice. When the above-mentioned driving continues, the fixed roller and the second cam surface engage with each other, and the fixed roller is lowered to the lower position of the movement stroke. This stretches the shirt downward and smoothes out wrinkles on the surface.

In this state, the hot plate is pressed onto the torso and the shirt is press-finished. In this case, since the front presser is located below the crimping range, no crimping marks from the front presser will be left on the shirt. In this state, press finishing is performed by expanding the air bag and pressing the hot plate.

〔Example〕

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 and 4, the torso 1 consists of a base plate 2 and a pair of air bags 3, 3' attached to both sides of the base plate 2. The inside of the body is a rectangular pipe that serves as a path for hot air to the air bags. It is attached to the top of 4.

A front presser 5 made of a T-shaped plate spring and a drive mechanism 6 for driving the front presser 5 are provided on the front surface of the rectangular pipe 4. Next, the drive mechanism 6 will be explained.

As shown in FIGS. 2 to 4, the square pipe 4
A sliding plate 9 is movably attached to the vertical rail 7 fixed to the front surface via a bearing 8, and a swinging block 10 is mounted on the upper end of the sliding plate 9 in the horizontal direction. It is attached so as to be able to swing toward the torso stand 1 via a shaft 11, and its swing block 1
The lower end of the front presser 5 is fixed to the upper part of the front presser 5.

An air cylinder 12 extending in the left-right direction is attached to the sliding plate 9, and a cam plate 13 is fixed to the tip of the piston rod of the air cylinder 12.

The cam plate 13 has a first end which has a horizontal surface 15a and the other end which has a vertically inclined inclined surface 15b.
It includes a cam surface 15 and a groove-shaped second cam surface 14 formed inside the cam plate 13, and the second cam surface 14 is inclined in parallel to the inclined surface 15b of the first cam surface 15. Inclined portion 14b and its inclined portion 14b
It consists of a horizontal part 14a that is continuous with the horizontal part 14a.

A movable roller 18 protruding from the front surface of the swinging block 10 engages with the first cam surface 15, while a fixed roller 18 attached to the square pipe 4 is disposed inside the second cam surface 14. A roller 16 is movably fitted while being guided by guide plates 17, 17 on both sides. Before starting the press, the position of the cam plate 13 is as shown in FIGS. 2 and 4, and in this case, the roller on the inclined surface 15b of the first cam surface 15 is The distance x from the contact position of the second cam surface 14 to the horizontal surface 15a is the distance
The distance y until contact with b is set to be smaller than the distance y by a predetermined amount.

In the above structure, when the air cylinder 12 is extended and the cam plate 13 is moved to the right in FIG.
The rocking block 10 is rocked by coming into contact with the roller 1 and rising along the inclined surface 15b of the roller 1.
8 rides on the horizontal surface 15a, the roller 16 comes into contact with the inclined portion 14b of the cam surface 14, and the sliding plate 9 descends along the engagement between the roller 16 and the inclined portion 14b. In this case, the horizontal surface 15a of the cam surface 15
The position of the front presser 5 is determined by the engagement with the roller 18.
is set to be crimped to the front of the torso stand 2,
Further, the end position of the inclined portion 14b of the cam surface 14 is such that the front presser 5 is in contact with the hot plate 1 when the roller 16 comes into contact with it.
It is set to be located below the crimping ranges 9 and 19.

This embodiment has the above-mentioned configuration, and before the press starts, the front presser 5 is set at a position facing the front surface of the torso stand 1, as shown in FIG. In this state, the front presser 5 is located away from the torso stand 1, and the front body of the shirt A can be easily inserted between the torso stand 1 and the front presser 5.

In this state, when the air cylinder 12 is extended and the cam plate 13 is moved, the roller 18 of the swing block 10 moves onto the cam surface 13, as shown in FIGS. 5 and 7.
5 from the inclined surface 15b to the horizontal surface 15a, the swinging block 10 swings toward the torso stand 1 about the shaft 11 as a fulcrum. Therefore, the upper part of the front presser 5 is pressed against the bodice 1, and the front body of the shirt A is pressed onto the bodice 1. On the other hand, the fixed roller 16
The sliding plate 9 does not move because it only moves on the horizontal plane 14a within the cull surface 14.

The air cylinder 12 further expands and the cam plate 13
As shown in FIGS. 6 and 8, when the fixed roller 16 moves the inclined portion 1 of the second cam surface 14, as shown in FIGS.
4b, and as it moves, the sliding plate 9 is pushed downward and moves downward along the rail 7.
In this case, since the roller 18 of the swing block 10 is moving on the horizontal part of the cam surface 15, the front presser 5
moves downward while keeping the front body of shirt A crimped. Therefore, the front body of the shirt A is stretched downward, and the wrinkles on the surface are smoothed out.

As shown in FIG. 8, the movement of the front presser 5 stops when the upper part of the front presser is located below the moving range of the hot plate 19, and then as the air bag 3 expands, the torso is raised. A hot plate 19 is crimped onto 1 and the shirt is press-finished.

When the press work is finished and the hot plate and air bag return to their original states, the air cylinder 12 contracts and the front presser 5
The sliding plate 9 moves in the opposite direction to the above-described operation and returns to the state shown in FIG. 2 before the start of the press.

As described above, in the above-mentioned embodiment, since the front presser can be moved in the front-rear direction and the up-down direction by driving one air cylinder, there is an advantage that the entire apparatus can be made compact.

〔Effect of the invention〕

As described above, in this invention, after the front presser is crimped to the front body of the shirt and pressed against the torso,
Since it is moved downward to tension the front body, the shirt can be press-finished with wrinkles sufficiently stretched out, and accurate and stable press-forming can be performed. Further, since there is no need for the operator to pull the bottom edge of the shirt to smooth out wrinkles as in the past, highly efficient and safe pressing operations can be performed.

Furthermore, when crimping the hot plate, the front presser can be moved downward to remove it from the crimping area of the hot plate, which eliminates crimping marks from the front presser from the finished surface of the shirt, resulting in a uniform gloss. You can get a beautiful finish.
