Although the device has been reduced in size and the space problem has been solved, the superheated steam is sprayed to finish the curtain into a corrugated sheet. As a result, it was impossible to pack immediately after finishing, and it was necessary to dry the remaining water. Therefore, it was necessary to remove it from the finishing device and hang the curtain in another place.

According to a first aspect of the present invention for solving the above-mentioned problem, a curtain comprising a textile fabric and having one or more stitches at a predetermined interval is suspended from the top, and the curtain is below the stitches. The part is bent in a zigzag cross section, and at least one of the front and back sides of the curtain is moved in the longitudinal direction of the curtain while superheated steam is jetted onto the curtain to make the zigzag bent part into its bent shape. Fixing and finishing the curtain into a corrugated plate shape, and then spraying hot air while drying the curtain while moving the jet nozzle part in the vertical direction, spraying superheated steam on the curtain and making the zigzag bent part Is fixed to the bent shape, and the starting position of the process of finishing the curtain into a corrugated plate is located at a predetermined distance from the memory or curtain hanging position, and hot air is injected. And a curtain finishing device, wherein the finishing of the starting position automatically performing the movement in the longitudinal direction of the injection nozzle portion as the start position or end position of the hot air injection when drying.

  According to the present invention, when a curtain of a thick fabric is finished with superheated steam, moisture remaining on the fabric can be dried with warm air. If it is possible to set whether or not to perform the drying process using warm air depending on the type of curtain fabric, the work can be performed more efficiently.

According to the present invention, the position of the finishing process is positioned so that the curtain finishing device is at a predetermined distance from the memory or curtain hanging position, so that the movement of the spray nozzle can be automated and the finishing can be performed efficiently. Processing can be performed.
The spray nozzle part is lowered from above the curtain for spraying superheated steam. However, when drying with warm air, the spray nozzle part is returned to the stored start position and lowered while spraying warm air again. Or finish by superheated steam while spraying superheated steam, switch to warm air from the lower end of the curtain and raise the spray nozzle while drying to start the finishing process by superheated steam It is possible to automatically perform an operation for ending drying.

A suction box 24 is provided on the frame portion 26 provided between 25 and 25. The suction box 24 sucks the jet from the jet nozzle portion 21 above the folding tool 23. The frame portion 26 has a structure that can be opened and closed in order to facilitate the installation of the curtain K and the arrangement of the corrugated plate with the fulcrum 25a above the opening and closing frames 25 and 25 as the rotation center when the curtain K is installed. It has become. On the side opened and closed by the opening / closing frame, a guide 32 having a spherical body having a size substantially the same as the arcuate portion of the injection nozzle portion 21 is provided at the top of the injection nozzle portion 21. The guide 32 and the jet nozzle portion 21 guide the wave-shaped peaks and valleys of the curtain K. (See Figure 5)

  As shown in FIG. 4, a plurality of the injection nozzle portions 21 are installed on the base 21 d, and a heater 21 a is installed on each injection nozzle portion 21. An injection hole 21b is provided above the heater 21a, and three injection nozzles 21c are provided in the injection nozzle portion 21 at both ends, and four in the other injection nozzle portions 21. (See FIG. 4 (b)) The base 21d is also provided with a plurality of base injection ports 21e. In order to control the temperature of the injection nozzle unit 21, a temperature sensor 21f is provided to control the heater 21a.

  The base 21d is provided with a steam valve 21g and controls opening and closing for injecting steam from a separately installed boiler (not shown) from the injection nozzle unit 21 and the base 21d. In addition, a valve 21h such as a solenoid valve is provided on the back side of the base 21d to control opening and closing for injecting air from a compressor or the like.

  The operation of the curtain finishing apparatus of the present invention will be described. First, the hook part 2 and the warping part 3 are moved to a position where the work can be easily performed using a switch in the operation box 27. The open / close frames 25, 25 are rotated to open the discrepancy between the folding tool 22 and the folding tool 23, the hooks of the curtain K are hooked on the holding portion 16 one by one, and the curtain K is suspended. The curtain K is hung between the folding tool 23 and the folding tool 23.

  When an operation switch (not shown) is pressed, the hook portion 2 is raised, and the hook portion 2 stops when the sensor 28 such as a photoelectric sensor no longer detects the curtain K. One of the sensors 28 is a light emitting sensor and the other is a light receiving sensor. If there is a curtain K, the light of the light emitting sensor is blocked, so the presence or absence of the curtain K can be confirmed. By this control, the position of the lower end of the curtain K is always set to be constant regardless of the length of the curtain K. The operation switch is not particularly shown, but if it is appropriately provided in the operation box 27 or appropriately provided as a foot switch for raising the hook part 2 or the warping part 3, the usability of the apparatus is improved. Therefore, it is preferable to provide as necessary.

  The open / close frames 25 and 25 are rotated to return the discrepancy between the folding tool 22 and the folding tool 23. If there is a part where the curtain K is not in the form of a clean corrugated plate, the operator corrects the part that is disturbed by hand before returning to the misalignment state, or in some cases, returns to the misalignment state between the folding tool 22 and the folding tool 23. In this state, only the warping part 3 is moved up and down so that the curtain K has a corrugated shape without any disturbance.

  Raise the warping unit 3 and stop at the position where the curtain K is to be processed into a corrugated plate shape, and press the operation switch. The spray nozzle portion 21 is rotated from the retracted position (the position indicated by the two-dot chain line in FIG. 2) by the operation of the air cylinder 20, and moves to a position where the curtain K has a corrugated shape. That is, as shown in FIG. 5, the injection nozzle portions 21 are respectively positioned in the valley-shaped portions of the curtain K that is corrugated. Since the heater 21a installed in the injection nozzle unit 21 is heated to a predetermined temperature, the steam valve 21g is opened, and steam from a boiler (not shown) flows into the base 21d. And superheated steam is injected from the injection port 21c of the injection nozzle part 21 installed in multiple numbers, and the base injection port 21e provided in the base 21d.

  At the same time as the superheated steam is injected, suction is started in the suction box 24 by the operation of the blower 29. Along with the above operation, the warping part 3 is lowered at a predetermined speed by driving the warping part motor 5, and the curtain K is processed into a wave shape. When the warping part 3 descends while finishing and reaches the lower end of the curtain K, the warping part 3 is detected by the sensor 28. When detected by the sensor 28, the warping section 3 reduces the moving speed, and the curtain K is folded back at the lower end to move the hem portion sewn at a low speed and finish processing with superheated steam. In the present embodiment, detection of the lower end of the curtain K and detection of the curving unit 3 are described only by the sensor 28, but detection of the lower end of the curtain K and detection of the curving unit 3 are detected by separate sensors. You may make it do.

  When finishing processing is performed with superheated steam for a predetermined distance (position where the folding tools 22, 23 do not come off the lower end of the curtain K) while the warping section 3 moves at low speed, the superheated steam is stopped and the warping section 3 Stop. The spray nozzle portion 21 moves from the curtain K to a position where it is retracted by the operation of the air cylinder 20 along with the stop of the setting section 3. (Position of two-dot chain line in FIG. 2)

  In a state where the injection nozzle portion 21 is retracted, the warping portion 3 is raised again to a position where finishing processing is started into a wave shape. At this time, if it is controlled so as to store the position raised for the first finishing, it can be automatically raised. By performing positioning control using a servo motor, an encoder, or the like for the warping section motor 5, it is possible to automatically operate.

  When the setting section 3 is raised and stopped, the operation switch is pressed again, and the air cylinder 20 is actuated to rotate from the retracted position (the position indicated by the two-dot chain line in FIG. 2), so that the curtain K becomes corrugated. Move to position. Since the heater 21a installed in the injection nozzle unit 21 is heated to a predetermined temperature, the valve 21h is opened to allow air from the compressor (not shown) to flow into the base 21d.

  The air flowing in from the compressor is injected from the injection port 21c and the base injection port 21e while being heated by the heater 21a, and is injected to the curtain K finished with superheated steam. In the fabric curtain K or the like, the superheated steam described above remains in the fabric and is not completely sucked by suction of the suction box 24. Therefore, following the finishing process, the remaining superheated steam is dried. In order to do this, the dough is dried by spraying warm air. Then, as in the finishing process of the curtain K, the curtain K is dried by spraying warm air from the spray nozzle section 21 and the base 21d while lowering the warping section 3.

  When the sensor 28 detects the warping portion 3, the warping portion 3 moves at a low speed as in the finishing process, and dries the skirt portion. In the drying process, the spray nozzle portion 21, that is, the warping portion 3, moves until it completely comes off from the lower end of the curtain K and stops. After stopping the warping unit 3, the valve 21 h is closed to stop the injection of warm air, and the injection nozzle unit 21 is moved to the retracted position by the operation of the air cylinder 20.

  Thus, a series of flow from the finishing process of the curtain K to the drying process is completed. Since the length of the curtain K is various, the start position of the finishing process is raised by the operator while judging the operator, but in the drying process, the previous start position is memorized and automated, After the finishing process is completed, the warping part 3 is raised and dried from the top of the curtain K. When the finishing process reaches the lower end of the curtain K, the steam valve 21g is closed and the valve 21h is opened to open the warping part. It is also possible to control to dry while raising 3. At this time, the warping unit 3 is stopped when the finishing process is started, and the injection nozzle unit 21 is retracted by the operation of the air cylinder 20. The step of ascending the warping part 3 can be omitted, and the finishing of the curtain K can be efficiently performed as the operation of the apparatus because the warping part 3 is in the raised position for finishing the next curtain K. It can be carried out.

  FIG. 6 illustrates another embodiment of the hook portion 2 and the warping portion 3. In the above-described embodiment, it has been described that the operator raises and stops the warping portion 3 after the hook portion 2 is lifted and stopped. In FIG. 6, a striker 30 is provided in the hook portion 2, and a sensor 31 for detecting the striker 30 is provided in the warping portion 3. Then, the positional relationship between the sensor 31 and the striker 30 is determined so that the state in which the sensor 31 has detected the striker 30 is the finishing position of the warping unit 3.

  When the hook part 2 is raised as appropriate by a foot switch (not shown) or the like as an operation switch, the warping part 3 is also controlled to rise continuously. When the raising of the hook portion 2 is stopped, the warping portion 3 is also stopped at the position where the sensor 31 of the warping portion 3 detects the striker 30 of the hook portion 2. By such control, the position of the warping portion 3 with respect to the hook portion 2 can be made constant.

  When the curtain K is suspended and the hook part 2 is raised, the warping part 3 is also raised. If the sensor 28 moves up to a position where the lower end of the curtain K is not detected, the hook portion 2 stops. Subsequently, the warping unit 3 also stops at the position where the sensor 31 detects the striker. When the foot switch (not shown) is operated as an operation switch, the warping unit 3 is already at the finishing processing start position, so that the injection nozzle unit 21 is moved to the retracted position (the position of the two-dot chain line in FIG. ) And the curtain K moves to a corrugated position, and the counter-warming part 3 descends and performs finishing while injecting superheated steam from the injection port 21c and the base injection port 21e.

  After finishing the finishing process, the setting section 3 is raised again and stopped at a predetermined position with respect to the hook section 2, and then the drying process is started when the setting section 3 is lowered and the drying process is performed. Then, the finishing process is completed, the drying process is performed while raising the warping unit 3, and the above-described sensor 31 is also controlled to perform the automated operation as the position where the striker 30 is detected in the same manner for the end position of the drying process. can do.

  Also in this embodiment, a necessary number of foot switches or the like are installed in the operation switch as appropriate, or the skirt of the curtain K is finished more reliably by moving the warping part 3 at a low speed during the finishing process and the drying process. Can do. Needless to say, the sensor 28 may only detect the bottom of the curtain K, and another sensor may be used to detect the warping portion 3.

  Further, in any of the embodiments, whether to control from the finishing process to the drying process depending on the type of the curtain K to be finished or to control only the finishing process as in the past is appropriately switched to the operation box 27 or the like. For example, a switch may be provided.

  Further, in addition to the above-described embodiment, a spray nozzle unit dedicated to finishing processing and a spray nozzle unit dedicated to drying are installed above the spray nozzle unit dedicated to finishing, respectively, and each spray nozzle is connected to an air cylinder as in FIG. Thus, the superheated steam may be sprayed from the spray nozzle part dedicated to finishing and the warm air may be sprayed from the spray nozzle part exclusively for drying. With such a configuration, it is possible to perform finishing processing and drying simultaneously by jetting superheated steam and warm air from the respective jet nozzle portions while simultaneously jetting them, so that the working time can be shortened. When the warping part descends to a position where the drying dedicated injection nozzle is located at the position where the finishing dedicated injection nozzle starts finishing, when the descent is lowered by a predetermined distance from the finishing processing start position, the drying dedicated injection nozzle retracts. It may be controlled to rotate from the position and start jetting of warm air.

The injection nozzle part 2 is moved up and down twice for finishing and drying, and the first injection nozzle part 21 is heated with superheated steam for the first time and the second time with hot air, so that the injection nozzle part is injected while superheated steam is injected. Since it passes through the same injection path as when it moved, while jetting warm air for the second time, it is possible to efficiently dry the moisture remaining with the hot air jetted when it descends the second time. Of course, even when the injection nozzle portion is provided exclusively for finishing and for drying, it can be efficiently dried by providing the injection port at the same position. Whether to make the spray nozzle part up and down twice or to have a dedicated spray nozzle part for finishing and drying in order to configure the device cheaply can be selected and implemented as appropriate Is possible.
