DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a sheet-like member.
The present invention relates to a sheet-like body folding apparatus for folding and fixing portions.

[0002]

2. Description of the Related Art The present applicant has previously developed a sheet-like folding apparatus for automatically folding a hem of, for example, curtain fabric and fixing the hem by sewing or the like. This sheet-like body folding device has two systems of transport means on the left and right sides, and continuously grips and transports the left end of the band-like portion to be folded by the left transport means, while simultaneously holding and transporting the left end of the band-like portion by the right transport means. Hold and transport the right end continuously. Furthermore, the transport path of the left transport means is twisted 90 degrees clockwise, the transport path of the right transport means is twisted 90 degrees counterclockwise, and the end sides (transmission sides) of the left and right transport means are mutually connected. Are arranged close to each other with their conveyance paths facing each other. Thereby, the sheet-like body is simply introduced into the transporting means in a flat state, and when the sheet-like body is sent to the sending unit side via the transporting means, the left end side and the right end side of the band-like portion of the sheet-like body face each other. It approaches the state of facing. Then, by fixing the opposing and adjacent portions by sewing or the like, the band-shaped portion of the sheet-like body is folded into two.

[0003]

By the way, for example, when treating a hem of a curtain, it is said that a predetermined width portion is folded and sewn from the cloth edge into three parts in order to prevent the cloth edge from being exposed to the outside. Generally, processing is performed. However, in the above-described conventional sheet-folding apparatus, usually only two-fold folding can be formed, and in order to fold the sheet-like body, the sheet-like body is set in the apparatus in a state where the cloth edge is double-folded in advance. In addition, it is necessary to feed the paper while adjusting the amount of folding so as not to fluctuate. However, this operation requires skill and is a difficult technique. There is also a method in which the cloth edge is folded in advance to perform temporary sewing, and the temporarily sewn sheet-like body is sent to an apparatus. However, the above-described temporary sewing is a complicated operation.

[0004] When a part of a sheet is folded, it is desired that the width (folding width) to be folded can be set to a desired length. For example, when forming the fold of the skirt of the curtain, it is necessary to change the setting of the fold width to be shorter or longer depending on consumer preference. In the above-described conventional sheet folding apparatus, the folding width can be changed by increasing or decreasing the distance between the introduction portions of the left and right conveying means. However, in the above-mentioned conventional sheet folding apparatus, in order to change the folding width, it is necessary to adjust the distance by moving the left and right transport means while manually measuring the interval between the introduction portions. This task was very complicated. Furthermore,
Since manual measurement is required, the method of measurement tends to vary depending on the operator, and there is also a problem that it is difficult to obtain an accurate folding width. Therefore, when the folding width is changed, it is necessary to perform trial sewing many times to confirm that a desired folding width is obtained, and this trial sewing requires a great deal of time and waste of a sheet-like body. Did not.

SUMMARY OF THE INVENTION In view of the above circumstances, it is an object of the present invention to easily and accurately fold the end portion of a sheet into three parts, and furthermore, it is possible for anyone to easily and accurately change the folding width. An object of the present invention is to provide a sheet-like body folding apparatus that can be used.

The second sending portion is arranged so as to be twisted in the other direction toward the sending portion, and the arrangement of the second sending portion is one of the one side sent from the first sending portion and the other side sent from the second sending portion. And a processing means for fixing the two side parts continuously sent to the first sending part and the second sending part to each other. A sheet folding device provided with a guide means for guiding an end portion of the sheet material aligned with the band portion so as to be folded over the band portion, provided at a stage preceding the second introduction portion. Configuration.

According to the first aspect of the present invention, the sheet-like body is sent to the first and second conveying means in a state where the sheet-like body is arranged along the guide means, so that the sheet is sent to the first and second conveying means. When the sheet is carried in, the end portion of the sheet is in a folded state, and the sheet is sent along the first and second transport means as it is to be further folded and fixed. As a result, it is possible to automatically fold the hem portion of the sheet into three and fix it.

According to a second aspect of the present invention, in the sheet folding apparatus according to the first aspect, the guide means includes a template facing a mounting table on which the band portion is mounted, and And a holding plate for holding the end portion bent along the template on the template.

That is, the fold of the end portion of the sheet is determined by folding along the template, and the end of the folded sheet is suppressed from above by the holding plate, so that the fold along the template is formed. Can be sent to the first and second transport means without shifting. Further, it can be realized by an inexpensive configuration.

According to a third aspect of the present invention, in the sheet-like body folding apparatus according to the second aspect, the guide means comes into contact with a side end of the end portion folded on the band-like portion, and The structure provided with the contact guide member for guiding the position of the side end.

According to the third aspect of the present invention, the end portion of the sheet-like body folded along the guide means is positioned from the side end by bringing the side end into contact with the contact guide member. Is determined. Therefore, it is possible to more easily and more stably stabilize the amount of folding of the end portion of the sheet-like body folded by the guide means. In addition, when the operator sets the sheet, it is sufficient that the side end of the sheet is in contact with the contact guide member, so that anyone can easily set the sheet without variation. Can be done. In addition, while the sheet is being fed, the operator only needs to check whether the side end of the sheet is in contact with the contact guide member. The sheet can be sent to the first and second conveying means.

According to a fourth aspect of the present invention, in the sheet folding apparatus according to the second or third aspect, a holding plate moving means for moving the holding plate from a position off the template to a position on the template. The configuration is provided with.

According to the fourth aspect of the present invention, the sheet can be easily set on the guide means. That is, when the holding plate is fixed on the template, when setting the sheet-like body, the sheet-like body is passed between the placing table and the template, and further, the end portion of the sheet-like body is folded back. It must be passed between the template and the holding plate, which is very complicated. On the other hand, in the present invention, first, when setting the sheet, the sheet is passed through the lower side of the template, placed on the placing table, and at a position off the template. The sheet is placed on the holding plate such that the end of the sheet is hooked. Then, by moving the holding plate onto the template by the moving means, the end portion of the sheet-like body hung on the holding plate is folded and sandwiched between the template and the holding plate to complete the setting. .

According to a fifth aspect of the present invention, there is provided a sheet-like body having at least one portion extending in one direction, which is folded in a direction in which the fold extends in the longitudinal direction, and which is fixed in such a manner as to be folded. A first introduction unit that continuously introduces one of the two side portions extending in the direction, a first conveyance unit that conveys while holding the side portion introduced from the first introduction unit, and Having a first sending section for continuously sending out the side portions conveyed by the first conveying section, and wherein the first conveying section is twisted in one direction from the first introduction section to the first sending section. The first transporting means configured, a second introduction portion for continuously introducing the other side portion of the two side portions extending in the longitudinal direction of the strip portion, and a side introduced from the second introduction portion. A second transport unit that transports the paper while holding the side portion, and A second delivery unit for continuously delivering the fed side portion, and the second transport unit is configured to be twisted in the other direction from the second introduction unit to the second delivery unit, The arrangement of the sending section is such that the side of one side sent from the first sending section and the side of the other side sent from the second sending section face each other and are set at a position where they face each other and are close to each other.
A sheet-like body folding apparatus comprising: transport means; and processing means for fixing two side portions continuously sent to the first sending portion and the second sending portion to each other, A moving mechanism for moving at least one of the first conveying means and the second conveying means so as to change a relative distance between the first introducing section and the second introducing section, and at least one of the first conveying means and the second conveying means; A driving means for driving one along the moving mechanism, an input setting means capable of inputting folding width data relating to a relative distance between the first introduction section and the second introduction section, Control means for driving the driving means to change the relative distance between the first introduction part and the second introduction part is provided.

According to the fifth aspect of the present invention, only by setting the folding width data using the input setting means, the control means automatically controls the first introduction portion of the first conveyance means and the second introduction means of the second conveyance means. The distance from the second introduction section is changed to a length corresponding to the folding width data. Since the distance between the first introduction part and the second introduction part is the length of the end of the band-shaped part to be folded in half, the folding width is determined by the distance between the first introduction part and the second introduction part. . Therefore, it is possible to change the folding width according to the folding width data only by inputting the folding width data. Therefore, the change setting of the folding width can be easily performed with good operability. In addition, there is no inconvenience that the setting of changing the folding width varies for each operator, and the folding width can be reliably set to a constant value regardless of who performs the setting.

A guide unit that guides the guide unit so as to fold over the band-shaped portion; and a guide moving mechanism that moves the guide unit so that the folding position of the end portion is changed. The guide means is configured to move in response to a change in the relative distance.

According to the sixth aspect of the present invention, as described in the first aspect, the skirt portion of the sheet-like body can be easily and reliably folded into three and fixed by the guide means. In addition, when the interval between the first introduction portion and the second introduction portion is changed to change the folding width, the position of the guide means can be automatically moved in accordance with the change. By the way, since the guide means is provided before the second introduction part, if the arrangement of the second introduction part is changed, the position of the guide means also needs to be changed accordingly. Also, if the folding width is changed, it may be necessary to change the length of the end portion folded inward. Therefore, according to the present invention, as described above, the first introduction section and the second introduction section
Since the guide means also automatically moves in response to the change in the distance from the introduction section, the change of the folding width can be automatically performed while having the function of fixing the folding in three. Further, for example, the fold position and the fold amount of the end portion of the sheet are changed according to the change of the fold width, so that even when the fold width is changed, the end portion of the sheet is normally folded. Can be done.

The movement of the guide means in response to the change in the distance between the first introduction part and the second introduction part means, for example, that the folding position of the sheet-like body folded by the guide means is changed to the second introduction part. The movement to follow. In addition, when the guide means has the template and the holding plate according to the second and fourth aspects, the guide means may be in the form of a guide means such as moving the template to follow the second introduction portion and causing the holding plate to follow the template. There can be various movements accordingly.

With this configuration, the position of the right end of the template 61 moves following the introduction portion of the right transport mechanism 4.

The contact guide member 65 is supported and fixed not on the support base 60 but on the upper frame 13A via the arm 65A. The abutting surface of the abutting guide member 65 (the abutting surface with which the side edge of the sheet-like body abuts) is usually set so as to be located at the center of the left and right transport mechanisms 2 and 4. By setting this position, the length of the end portion folded inward in the three-folded sheet body can be the same as the folding width. When it is desired to reduce the amount of folding at the end portion folded inward, the fixing position of the arm 65A is shifted and the contact guide member 65 is moved laterally. Since the contact guide member 65 is held by the arm 65A in a vertically movable state, the contact guide member 65 follows the vertical movement of the template 61 without hindering the vertical movement of the template 61.

The side end upper feed body 66 is a mechanism for pressing the side end of the sheet from above through a belt provided on a pulley. The side end upper feed body 66 is attached to the arm 65A via the interposed member 66A and the actuator 66B, and is moved up and down by the operation of the actuator 66B.

Next, the operation and operation of the sheet folding apparatus 1 having the above configuration will be described. First, a setting operation using the operation panel 9 will be described. The setting items using the operation panel 9 include the setting of the folding width of the sheet-like body (the width of the folded portion) and the sewing start length (from the leading end to the start of sewing when viewed in the feeding direction of the sheet-like body). Length) and setting of the sewing type such as the sewing pitch.

First, one of the above setting items is selected by operating the control key 9B (FIG. 1) of the operation panel 9, and then a data value is inputted by operating the ten key 9C. Further, it is performed by turning on the set key of the control key 9B. When the set key is turned on,
The CPU 82 writes the previously input data value into a predetermined storage area in the RAM 83. When the setting item is the folding length, if the set key is turned on to set data, the following processing is further performed. That is, when the data is set, the CPU 82 recognizes the driving amount of the opening / closing servomotor 18 based on the encoder output of the servomotor encoder 18d. Then, from the driving amount of the opening / closing servomotor 18, the opening / closing amount between the introduction portions of the left and right conveyance mechanisms 2 and 4 and the folding width (half the length between the introduction portions of the left and right conveyance mechanisms 2 and 4) are obtained. . Further, the folding width length is compared with the inputted folding width data, and the drive of the opening / closing servomotor 18 is controlled so as to correspond to the folding width data. The right and left transport mechanisms 2 and 2 are driven by an appropriate driving amount of the opening / closing servomotor 18.
4 are automatically opened and closed to automatically change the length corresponding to the input folding width data. Further, the support base 60 (FIG. 8) of the template 61 and the support base 74 of the holding plate 62 move following the opening / closing operation.
The template plate 61 and the holding plate 62 are moved by the same amount as the movement of the introduction section.

Next, a description will be given of the pedal operation and operation when setting the sheet-like body in the folding device 1. FIG. 10 is a front view for explaining the flow of the operation of the guide mechanism 6, and FIGS.
(D) shows a diagram from the start of the setting of the sheet to the completion of the setting.

In the initial state, as shown in FIG. 10 (a), the side end upper feed body 66 and the template 61 rise to a position higher than the front table 10, and the holding plate 62 lowers to the height of the front table 10. It is in the position that I did. In addition, the left and right transport mechanisms 2,
Left and right upper feed bodies 30 respectively provided at the introduction section of 4,
The front frames 32 and 52 of 50 are raised, and the conveyor belt 2
4, 44 and the belts 36, 56 of the upper feed members 30, 50 are open at the introduction portion. Then, in this initial state, the sheet Q is set on the front table 10. At this time, the sheet Q is set between the template 61 and the front table 10 while the end portion Q4 is placed on the holding plate 62. The sheet is inserted so that the leading side of the sheet slightly overlaps the introduction portions of the left and right transport mechanisms 2 and 4. As shown in FIG. 8, a scale 62 extending left and right from an end of the holding plate 62 is provided on the holding plate 62.
a, and a ruler 62b that can move to the left and right. The side end of the end portion Q4 of the sheet Q is set in a state in which the length is determined by contacting the ruler 62b. Note that the contact ruler 62b can be manually moved left and right by loosening the set screw 62c, and by changing the position of the contact rule 62b based on the scale 62a,
The folding amount of the end portion Q4 in the sheet state Q can be adjusted accurately.

Here, the operator depresses the pedal 8A once and releases it. Then, first, the CPU 82 receives the detection output of the left cloth detection sensor 32a and checks whether or not the sheet Q is set in the introduction portion of the left transport mechanism 2. And if you can not confirm that it is set,
Although the process does not proceed and remains stopped, when the set is confirmed, the next first stage process is performed. That is,
By operating the actuator 33 (FIG. 5) of the upper feed body 30 on the left side, the opened introduction portion of the left transport mechanism 2 is closed. Further, the actuator 61C (FIGS. 8 and 9) is operated to lower the template 61 until it comes close to the front table 10.
At this time, a slight gap is secured between the front table 10 and the template 61, and does not hinder the smooth feeding of the sheet Q. Further, the cloth locking member 71 is raised to temporarily lock the sheet Q.

After the first-stage processing has been performed and it is confirmed that there is no abnormality, the operator depresses the stepping pedal 8A once more and releases it. Then, the process of the second stage is started. As shown in FIGS. 10B and 10C, this process is completed by being moved to the center after the actuators 75 and 76 operate and the holding plate 62 is raised. By this processing, the end portion Q4 of the sheet Q on the holding plate 62 is folded along the right side of the template 61 and held between the template 61 and the holding plate 62. The operator determines here whether the side end of the sheet Q is appropriately abutted on the contact guide member 65 having an L-shaped cross section, whether the sheet Q is displaced during folding of the end portion Q4, and the like. Is confirmed, and if there is no abnormality, the process proceeds to the next third stage process. If there is an abnormality and the user wants to correct it, he operates the lever pedal 8B. Then, each actuator operates to return to the state one step before. The operator can start the process again from the returned stage.

The processing in the third stage is started by once again depressing and releasing the pedal 8A after the processing in the second stage is completed. In the process of the third stage, as shown in FIG. 10D, the actuator 66B operates to lower the side end upper feed body 66 onto the contact guide member 65, and further the right upper feed body 50 The actuator 53 operates to close the open introduction portion of the right transport mechanism 4 and the operation is completed. Thus, the side end of the sheet Q is gripped between the contact guide member 65 and the belt of the side end upper feed body 66. Also,
The right side Q3 and the end Q of the strip Q1 of the sheet Q
4 is gripped by the introduction portion of the right transport mechanism 4.
As described above, the setting of the sheet Q is completed by the processes of the first to third stages. In the processing of the first stage to the third stage, if the depression pedal 8A is not depressed and released, the processing of the first stage to the third stage can be continuously performed without stopping when the processing of each stage is completed. I can do it.

Next, a description will be given of an operation and an operation of sending the set sheet-like material Q to the left and right transport mechanisms 2 and 4 for sewing. 12A and 12B are diagrams illustrating a process in which the sheet Q is folded by the folding device 1, and FIG.
Is a longitudinal sectional view of the sheet Q after passing through the folding device 1, (b) is a diagram of the sheet Q showing a flow in the middle of passing through the folding device 1, and (c) is a diagram of the sheet Q. FIG. 3 is a diagram of a sheet Q in a set state.

When the setting of the sheet Q is completed as described above, the sheet Q is fed by driving the right and left transport mechanisms 2 and 4. The feeding of the sheet Q is performed by depressing the stepping pedal 8A. That is, the sheet Q
When the stepping pedal 8A is depressed after the setting is completed, the left and right servo motors rotate under the control of the CPU 82, and the left and right transport belts 24 and 44 are driven. Thereby, as shown in FIG. 12C, the left side portion Q2 of the band-shaped portion Q1 is gripped and transported following the transport belt 24 of the left transport mechanism 2. At the same time, the belt Q1 is gripped and transported following the transport belt 44 of the right transport mechanism 4 in a state where the right side Q3 of the strip Q1 overlaps the side of the end Q4. During this conveyance, if the pedal 8A is released, the left and right conveyance mechanisms 2 and 4 stop, and the sheet Q also stops.

As the sheet Q is transported, FIG.
As shown in (b), the side portions Q2 and Q3 of the belt-shaped portion Q1 change their directions vertically according to the twist of the transport belt,
In addition, they come close to each other with their surfaces facing each other. When the sheet Q is conveyed, the leading end of the sheet Q in the feed direction approaches the workpiece 100. When the sheet Q approaches the needle drop position of the workpiece 100, the cloth detection sensor 95 detects that the sheet Q has arrived and outputs a detection signal to the CPU 82. The CPU 82 receives this detection signal and calculates how much more should be sent before activating the workpiece 100. This calculation process is performed based on the sewing start data input from the operation panel 9 so that the sewing is started at the position indicated by the sewing start data. Then, the workpiece 100 is operated at the timing at which the feed indicated by the calculation result is performed.

The count value data of the encoder 99 of the sewing machine head 91 is input to the CPU 82.
82 controls the driving of the left and right transport mechanisms 2 and 4 in synchronization with the movement of the needle bar 92 based on the count value data. That is, the feeding is stopped while the needle 93 is stuck in the sheet Q, and the feeding is performed while the needle 93 is out of the sheet Q. Then, as shown in FIG. 12A, the band-shaped portion Q1 and the end portion Q4 of the sheet-shaped body Q folded in three.
Are sewn at a predetermined sewing position V.

When the sheet Q is fed and the end of the sheet Q viewed in the feed direction approaches the left and right transport mechanisms 2 and 4, the cloth detection sensor provided at the introduction portion of the left transport mechanism 2 32a detects that the end of the sheet Q has passed, and outputs it to the CPU 82. The CPU 82 drives the left and right transport mechanisms 2 and 4 and
0 is temporarily stopped.

By this stop, when there is a sheet to be processed next, the operator can set the sheet to be processed next by the above-described operation and processing.
After setting, the left and right transport mechanisms 2 and 4 and the workpiece 100 are driven by operating the pedal device 8 again as described above, and the folding process of the sheet-like body Q that has stopped halfway is performed. And the sewing process is continued. When the sewing of the preceding sheet Q is completed to the rear end, the sewing of the next sheet is started by the above-described processing. That is,
By this processing, when processing a plurality of sheet-like bodies, it is possible to eliminate the time in which the left and right transport mechanisms 2 and 4 play without processing, thereby shortening the overall processing time.

If the sheet is stopped based on the detection of the end of the sheet Q but there is no sheet to be processed next, an input operation is performed through the operation panel 9 to indicate that this sheet is the final processing. By this operation, the left and right transport mechanisms 2 and 4 and the workpiece 100 can be driven without operating the pedal device 8 again, and folding and sewing can be performed to the end of the sheet Q.

As described above, according to the sheet folding apparatus 1 of this embodiment, the guide mechanism 6 feeds the sheet Q in a state where the end portion Q4 of the sheet Q is folded by one. Since the left and right transport mechanisms 2 and 4 further fold and sew the sheet, the hem portion of the sheet Q can be automatically folded into three and sewn. Also,
Since the guide mechanism 6 is composed of the template 61 and the holding plate 62, the end portion Q4 of the sheet Q can be easily and reliably formed.
Can be guided to fold. That is, the fold of the end portion Q4 of the sheet-shaped body Q is determined by folding along the template 61, and the end portion Q4 of the folded sheet-shaped body Q is suppressed from above by the holding plate 62. The folds along the plate 61 can be sent to the left and right transport mechanisms 2 and 4 without shifting. Further, it can be realized by an inexpensive configuration.

Further, the end portion Q4 of the sheet Q folded along the template 61 has its side end in contact with the contact guide member 65, so that the position of the side end can be determined. 6, the amount of folding of the end portion Q4 to be folded can be stabilized more easily and more reliably. When the operator sets the sheet Q, the sheet Q
Can be set so that the side end of the sheet member Q abuts on the contact guide member 65.
Can be set. In addition, while the sheet Q is being fed, the operator only needs to check whether the side end of the sheet Q is in contact with the contact guide member 65, and anyone can easily perform the folding amount without variation. Thus, the sheet Q can be sent to the left and right transport mechanisms 2 and 4.

The holding plate 62 is connected to the actuator 74,
By the operation of 76, the template 61
Since the sheet Q moves upward, the sheet Q can be easily set on the guide mechanism 6. That is, when the holding plate 62 is fixed on the template 61, when setting the sheet Q, the sheet Q is passed between the front table 10 and the template 61, and Must be passed between the template 61 and the holding plate 62 in a state in which the end portion Q4 of the holding plate 62 is folded, which is very complicated, but by moving the holding plate 62 onto the template 61, The end portion Q4 of the sheet-shaped body Q is folded and sandwiched between the template 61 and the holding plate 62, and the setting is completed.

Further, just by setting the folding width data using the operation panel 9, the controller 81 automatically changes the interval between the introduction section of the left transport mechanism 2 and the introduction section of the right transport mechanism 4 to the folding width data. Since the length is changed to the appropriate length, the fold length change setting can be performed easily and with good operability, and the fold length change setting can be set to a certain fold width no matter who makes the change. I can do it. When the folding width is changed, the template 61 and the holding plate 62 of the guide mechanism 6 automatically move corresponding to the right transport mechanism 4, so that the fixing position of the guide mechanism 6 is manually changed. There is no need to relocate or relocate.

The present invention is not limited to the sheet folding apparatus 1 of this embodiment. For example, the sheet to be processed is not limited to curtain fabric, and can be applied to various sheet-like bodies, and the place to be processed may be a part other than the hem. Further, the guide means may be configured not to use the template plate and the holding plate but to guide in a state where the end portion is folded by using other various structures and methods. In addition, the configuration for moving the holding plate may be manually performed without using electric control. Also, the first introduction part and the second introduction part
The mechanism for opening and closing the introduction unit is not limited to the double-opening structure as in this embodiment, but may be a mechanism for opening and closing by moving one of the moving means. Further, other processing means such as welding or pressure bonding may be used as the processing means. In addition, the specific configuration of the inside of the left and right transport mechanisms 2 and 4, the operation method and operation of the guide mechanism 6 when setting the sheet-like body, the operation method and operation when folding the sheet-like body, etc. The detailed structures and methods specifically illustrated in form are
Changes can be made as appropriate without departing from the spirit of the invention. In addition, a guide mechanism 6 is provided at an introduction portion of the right transport mechanism 4 and at a preceding stage thereof.
Instead of, for example, by combining a device that can perform centering such as overlock sewing machine, it is folded and sewn after centering. You can do it.

[0067]

As described above, according to the present invention, the first
Before the sheet is sent to the second conveying means, the end of the sheet is folded by the guide means, so that the skirt of the sheet can be automatically folded in three and fixed.
Further, by forming the guide means with the template, the holding plate, and the contact guide member, the sheet-like body can be easily and reliably guided. Further, the configuration can be realized at low cost. In addition, the configuration in which the holding plate is moved at the time of setting the sheet can easily set the sheet.

Since the first and second transport means are automatically arranged and moved by inputting the folding width data to the setting input means,
The fold length can be accurately set by anyone with good operability. In addition, when the first and second transport units are arranged and moved, the guide mechanism automatically moves in accordance with the arrangement movement. The setting can be changed easily and reliably.
