Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a mechanism for a hem screen of a product workpiece when it is treated with steam, hot air, vacuum, etc. in a clothing finishing device.

[Conventional technology]

Conventionally, in order to make knitted products, especially woolen sweaters, etc., a single piece of raw material cloth was folded in half.
The sides were sewn with a sewing machine to form a bag-shaped intermediate material with one end open, and this was then cut into a predetermined shape and size to obtain the front and back sweater bodies. In order to ensure good quality/handle etc. of these sweaters when finished, processes such as finishing and sizing of the above-mentioned material before cutting are important. etc. were used, and various processing steps were performed, such as a combination of steam injection and vacuum suction, or a combination of steam injection and hot air blowing.

As an example of improvements in this type of finishing equipment,
A device as shown in FIG. 4 has been proposed by the same person as the inventor of the present application. This proposed example uses an adjustable dummy to perform steam blowing, hot air blowing, vacuum suction, etc. from the inside of the dummy, thereby improving the stability and texture of the workpiece material. It is.

The general configuration will be explained below. Figure 4 shows
FIG. 3 is an external perspective view of the clothing finishing device cited above.

1 is a porous dummy with a width expandable internal cavity formed on the base frame F, and a central dummy 1a
and side dummies 1b on both sides, and both side dummies 1b are configured so that they can be moved/expanded and contracted to the left and right by operating the handle 9 relative to the fixed central dummy 1a to adapt to the width size of the product workpiece. has been done. 1c shows a number of small holes on the dummy surface.

C is an upper fabric cover that is placed over the dummy 1, which covers the dummy 1 together with a lower fabric cover (not shown), and the product workpiece is placed on top of it and set.

Inside each dummy 1, a steam blow pipe, a heat insulation pipe, etc. (not shown) are arranged.

Reference numeral 2 arranged on the base frame F is a power switch, 3 is a start switch, 4 is an emergency stop switch, and 5 is an operation switch for the hem presser 11 (each time the pedal is pressed, the hem presser 11 of the workpiece opens/ (alternately repeating closing). Further, 6, 7, and 8 are operation switches for steam, hot air, and vacuum, respectively, and can be manually selectively used to supply each from an external supply source (not shown) only while each pedal is depressed. . Moreover, 12 is a disposal bag hanger for a product workpiece with a disposal bag.

Reference numeral 14 denotes a control microcomputer (microcomputer), and when the start switch 3 is pressed and released, each microcomputer-controlled timer is activated according to a predetermined program, independently of the manual switches 6, 7, and 8. It was configured to supply steam, hot air, and vacuum from the respective sources.

[Problem that the invention attempts to solve]

However, in the configuration of the conventionally proposed example as described above, when focusing on the hem presser 11 device for the workpiece, the height position of the hem presser member 11 is fixed, so that it cannot be placed over the dummy 1. When the length of the set product workpiece is short (length, length size), it is not possible to press the hem, and conversely, when it is too long, it is difficult to press the hem effectively. In such cases, it is necessary to change the width of the hem presser member 11 to suit each case.

Furthermore, when the length of the product workpiece is short, the surface of the dummy 1 between the device base frame F and the hem presser member 11 above the bottom edge of the product workpiece hem is opened, so that steam and vacuum are effectively dissipated from each small hole. There are various problems such as leakage and loss of efficiency, danger to workers due to steam spewing out from that part, and inconvenience as there is no reference mark for adjusting the dimensions of the hem of the workpiece. There was a problem.

The present invention has been made in view of the problems of the conventional proposals as described above, and aims to solve the above-mentioned drawbacks by providing an adjustable screen device at the bottom of the dummy.

[Means for solving problems]

Therefore, the present invention attempts to achieve the above object by providing a pair of roll-up vertically adjustable screens on the lower part of the dummy on the base frame of the device.

[Effect]

With the above configuration, the height can be varied according to the size of the product workpiece by adjusting the screen vertically, thereby eliminating the dummy gap, preventing steam and vacuum from leaking out, and It can be used as a mark for setting the workpiece hem dimension.

〔Example〕

The present invention will be explained below based on examples.

FIG. 1 shows a view corresponding to FIG. 4 of the aforementioned conventional example equipped with an embodiment of the hem screen device according to the present invention. The same (equivalent) components as in Figure 4 are:
They are represented by the same reference numerals, and redundant explanation will be omitted. Also,
2 is a cutaway perspective view of the main part in FIG. 1 as seen from the direction of arrow A, and FIG. 3 is a cutaway perspective view of the main part seen from the direction of arrow B in FIG.

(Configuration) In FIG. 1, 20 is a guide (not shown) provided on the side surface of the device base frame F, respectively.
A pair of left and right vertically movable columns S, which can move in the vertical direction along Fixed 2
The ends of each book are fixed to the book rods 25, and the lower ends are wound up by a pair of rolls R (see Figure 2, there are rolls on the front and rear sides) that are pivotally supported on the left and right frames F, respectively. The roll R is biased by a torsion spring (not shown) or the like in a direction of rotation that constantly pulls and tensions each screen downward.

FIG. 2 shows the movement/drive mechanism of each vertically movable column 20, and only one side of the both sides of the frame F is shown. Each vertically movable column 20 is configured to be able to slide up and down along a guide (not shown) on the frame F, and this lifting/lowering operation is performed by a long shaft 28 fixed to one end of a long shaft 28 pivotally supported on both sides of the frame. This is done using the rotary handle 10. A sprocket wheel 29 is fixed to the outside of the frame F of the shaft 28, and a chain 32 is wound endlessly between the sprocket wheels 33 separately provided below each sprocket wheel 29, and a part of the chain 32 At 34 it is connected to the lower end of the vertically moving column 20, and at another part 35 it is connected to a counterweight 36. The weight 36 can slide vertically up and down along a channel-shaped guide 37, and the weight of the weight 36 is slightly greater than the weight of the vertically moving column 20 (including the screen S and its tension resistance). be.

Further, each roller R is rotatably supported on a pair of shafts 26 supported between the side surfaces of both frames.
Due to a torsion spring (not shown), etc., the screen S is always
is biased in the direction of winding rotation.

On the other hand, in FIG. 3, a ratchet wheel 31 is fixedly installed inside the frame of the shaft 28, and a reversal prevention pawl 38 is biased so as to always engage with the ratchet wheel 31 by a tension coil spring 40.
are meshing together. This claw 38 has a release lever 3
9 is provided, and an elongated hole 41 bored in the frame F.
The end is exposed to the outside of the frame by penetrating it.

The above ratchet mechanism and operating handle may be provided only on one side of the frame F.

(Operation) Next, the operation in the above configuration will be explained. First, in order to raise the screen S, that is, the vertically moving column 20, it is sufficient to rotate the handle 10 in a predetermined direction (to the right in the illustrated example).When the handle rotation is stopped, the screen S, that is, the vertically movable column 20, can be raised from the roll R by the ratchet mechanism. The screen S also stops at that position and does not turn around. Also, screen S
To lower the lever, hold down the ratchet release lever 39 and rotate the handle 10 in the opposite direction.
The screen S is caught in the roll R and descends,
The position is maintained by stopping the rotation of the handle and returning the release lever 39. In any of the above cases, due to the presence of the counterweight 36, the operating force can be extremely small.

[Other Examples]

In the above embodiments, a handle that drives a sprocket/chain is used as the drive mechanism of the vertically moving column, but the present invention is not limited to this, and other reciprocating mechanisms or a handle with a brake are used. Of course, a power operating mechanism such as a motor or an air cylinder may also be used, and the counterweight may be replaced by a spring or the like. [Effects of the invention] As explained above, according to the invention, the screen position can be adjusted upward or downward depending on the size of the product workpiece.
By adjusting it downward, it prevents steam and vacuum from leaking out and improves efficiency, and also prevents danger to workers due to steam gushing, etc.
We were able to provide a guideline for determining the dimensions of the hem of the product workpiece.
