Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet-like body folding apparatus for folding and fixing a part of a sheet-like body, which is a useful technique, for example, for sewing the upper edge of a curtain.

[0002]

2. Description of the Related Art The applicant of the present invention firstly sewed a sheet-like body such as a cloth for a curtain by automatically folding the upper edge and the hem of the sheet into two or three sheets and sewing them. Has developed a folding device, and has developed the patents No. 2986101 and No. 29861.
No. 02, No. 3079377, and No. 311412.
Japanese Patent No. 1 discloses the basic configuration and applied technology.

This sheet-shaped folding device has two left and right sides.
Introducing an upper edge portion or a hem portion of the sheet-like body, that is, a strip-shaped portion (strip-shaped portion) for folding into two or three sheets, and introducing the left end of the strip-shaped portion to the left. While the conveying means continuously grips and conveys, the right end of the strip portion is continuously grasped and conveyed by the right conveying means. Furthermore, the transport path of the left transport means is twisted 90 degrees in the right rotation direction, the transport path of the right transport means is twisted 90 degrees in the left rotation direction, and the end sides of both transport means face each other. It is placed close to each other. Thus, when the sheet-like body is introduced into the conveying means in a flat state, when it is sent to the terminal side of the conveying means, the strip-shaped portion of the sheet-like body is folded and folded out into two pieces. Then, the folded portions are sewn together by a sewing machine or the like, so that the band-shaped portion of the sheet-like body is processed into two pieces.

In addition, as one of the processing for the upper edge of the curtain, a process of folding the upper edge of the body cloth into two pieces (concealment processing), and sandwiching a strong band-shaped core material between them There is a centering process for sewing.

In order to automate such processing,
The present applicant has added a configuration in which a core material is introduced into the conveying means on the right side of the folding device, and a core material processing means for connecting the core material to a sheet-like body in the middle of the conveying path on the right side. The invention is proposed in Japanese Patent Application No. 2001-50508.

[0006]

By the way, in the manufacture of curtains, a name tag (tag piece) for indicating the manufacturer's name or quality may be attached to a part of the curtain.

FIG. 7 is a view showing the attachment positions of the left and right curtain name tags, and FIG. 8 is a sectional view taken along the line AA of FIG. Note that FIG. 7 shows a stage in which the vertical curtain pleats have not yet been formed. In these figures,
Q1 and Q2 are curtain fabrics, NT is name tag, V
Reference numeral 1 is a seam that has been turned upside down, and R is a core material.

As shown in FIG. 8, the name tag NT has body materials Q1 and Q, which accompany the stitching process of the fold-over processing.
It is common to sew on 2. Further, as shown in FIG. 7, in the type of curtain that can be attached to the window in a pair on the left and right, the name tag NT is the curtain cloth Q1 on the left
For the side closer to the left end, the right side curtain fabric Q2
It is said that it is preferable to attach it to the side closer to the right end. In particular, in the case of a lace curtain or a curtain with little light-shielding property, the shadow of the name tag NT may be visible from the front side of the curtain, so it cannot be installed in a prominent position near the center.

Further, in the production of order curtains, it is assumed that a plurality of sets of curtains having different colors and patterns are continuously processed, but in such a case,
It is more convenient to process the right curtains collectively after processing the left curtains collectively than to process the right curtains separately, because the curtains in each set do not become disjointed. That is, when processing a plurality of sets of curtains continuously, it is common practice to process the left and right curtains continuously in the order of left, right, left and right.

FIG. 9 is a diagram for explaining the attachment position value of the name tag in the case where a pair of left and right curtains are continuously processed in the order of left, right, left and right. In the figure, Q1 is a left curtain, Q2 is a right curtain, and X is a name tag attachment position.

When a pair of left and right curtains Q1 and Q2 are continuously machined to the left and right and to the left and right, the mounting position X of the name tag is alternately switched between the leading side and the rear side in the processing direction for each curtain. Therefore, assuming that the attachment of the name tag is automated, if the attachment positions can be set only in one way, it is necessary to change the setting every time and the operability is deteriorated.

Further, as shown in FIG. 9, when the mounting position X of the name tag is alternately switched between the leading side and the rear side for each curtain, after mounting the name tag on the leading side of one curtain, When it is attached to the rear side of the curtain, the attachment interval of the name tag becomes large twice (interval L1), but when it is attached to the rear side of one curtain and then to the front side of the next curtain, it becomes twice. The name tag installation interval becomes smaller (interval L2),
The problem that the time margin of the mounting process also becomes small was considered.

An object of the present invention is to make it possible to attach a tag piece such as a name tag with a beautiful finish and good operability in a sheet-like folding apparatus for automatically performing a folding operation of a curtain. is there.

Another object of the present invention is to make it possible to perform processing with good workability even when the attachment positions of the tag pieces alternate between the leading side and the rear side of the sheet-like body. is there.

[0015]

In order to solve the above-mentioned problems, the invention according to claim 1 is characterized in that both side portions of a unidirectionally long strip-shaped portion which is at least a part of the sheet-shaped body are respectively referred to as a first conveying portion. A transporting unit that folds the strip-shaped portion in a direction in which the folds extend in the longitudinal direction by gripping the second transporting unit and transporting them so as to approach each other while twisting in opposite directions; A folding device for a sheet-like body, comprising: a processing means for performing a bonding process on a portion where the band-shaped portions are folded, a gripping member capable of gripping or releasing a tag piece, and a transport path for the gripping member. And a first moving mechanism for moving the gripping member by the first moving mechanism so that the tag piece gripped by the gripping member can be moved between the transport path of the first transport unit and the second transport unit. Is it a gap position with the transport path? At least both side portions of the strip-shaped portion are brought close to each other and are conveyed to a position where the tag piece is fixed to the strip-shaped portion, and the tag piece is attached with the joining processing of the strip-shaped portions by the processing means. It is configured to be coupled to the strip.

According to the invention of claim 1, the tag pieces can be automatically joined together with the folding process of the sheet-like body, and the movement timing of the gripping member is controlled. With this, it is possible to easily control at which position in the longitudinal direction of the strip portion the tag piece is coupled.

Here, the position where the tag piece is fixed to the band-shaped portion is specifically, for example, a position where the tag piece is fixed by being sandwiched between the folded portions of the band-shaped portion, or by joining by a processing means. For example, the position where the tag piece is fixed to the strip portion.

According to a second aspect of the invention, in the sheet-like folding apparatus according to the first aspect, the first moving mechanism is configured so that the gripping member moves in synchronization with the carrying movement of the carrying means. It was done.

According to the second aspect of the present invention, even when the processing speed of the sheet-like body changes in the middle,
Since the moving speed of the tag piece is also changed accordingly, the attachment position of the tag piece does not shift. Further, even when the tag piece is fixed to the strip-shaped portion, the tag piece and the strip-shaped portion move in synchronization, so that the tag piece may tilt or wrinkle even if the processing speed of the sheet-like body changes. You can fix the tag piece neatly without doing. Therefore, the operator is not distracted by the attachment of the tag piece,
When necessary, the processing of the sheet-like material can be stopped or the processing speed can be changed to concentrate on the folding processing.

According to a third aspect of the present invention, in the sheet-like folding apparatus according to the first or second aspect, the grip member is moved to a position where the tag piece reaches at least a coupling processing point of the processing means. The first moving mechanism is configured so as to perform the above.

According to the third aspect of the present invention, since the tag piece is held by the holding member until it is firmly fixed, the tag pieces can be joined with a beautiful finish.

According to a fourth aspect of the present invention, in the sheet-like folding apparatus according to the first or second aspect, the first moving mechanism extends to a position at which the tag piece passes the joint processing point of the processing means. The holding member is moved.

According to the fourth aspect of the present invention, the tag piece is held by the holding member until the tag piece joining process is completed. Therefore, the tag piece can be joined to the strip portion with a more beautiful finish. , It is possible to prevent the attachment failure of the tag piece.

According to a fifth aspect of the present invention, both side portions of a unidirectionally long belt-like portion which is at least a part of the sheet-like body are held by the first conveying portion and the second conveying portion, respectively, and are in opposite directions. And a conveying means for folding and folding the strip-shaped portion in a direction in which the fold extends in the longitudinal direction by twisting and transporting the strip-shaped portion so that the strip-shaped portion is joined by the transporting means. In a sheet-like folding apparatus including a processing means, a tag piece arranging mechanism that sets a tag piece at an arbitrary position in the longitudinal direction of the belt-shaped portion while the belt-shaped portion is being conveyed by the conveying means, and the tag piece. A setting means for setting the setting position of the tag piece by the arrangement mechanism, and the tag piece set by the tag piece arrangement mechanism is joined to the belt-like portion in association with the joining processing of the belt-like portion by the processing means. At the same time, the setting means automatically sets the set position of the tag piece for each sheet-shaped body to the leading side and the rear side of the belt-shaped portion when the plurality of sheet-shaped bodies are sequentially processed. The configuration has a setting pattern that is alternately repeated.

According to the invention of claim 5, the set position of the tag pieces is alternately changed to the front side and the rear side of one sheet-like body by the above setting pattern. The operability is improved because it is not necessary to change the setting of the tag piece attachment position for each sheet when processing the set of curtains in the left-right-right order.

According to a sixth aspect of the present invention, both side portions of a belt-like portion which is at least a part of the sheet-like member and is long in one direction are held by the first conveying portion and the second conveying portion, respectively, and are in opposite directions. And a conveying means for folding and folding the strip-shaped portion in a direction in which the fold extends in the longitudinal direction by twisting and transporting the strip-shaped portion so that the strip-shaped portion is joined by the transporting means. In a sheet-like folding apparatus including a processing unit, a first gripping member that grips a tag piece on the front side of the device when viewed in the transport direction of the transporting unit, and the first gripping member on the front side of the device. From the inside to the inside of the device, and a second gripping member that grips the tag that is gripped by the first holding member and sent to the inside of the device.
A second moving mechanism for moving the second gripping member to the vicinity of the transport path of the band-shaped portion, and the tag piece gripped by the second gripping member and transported to the band-shaped portion by the second moving mechanism. Is configured to be joined to the strip-shaped portion with the joining processing of the strip-shaped portion by the processing means.

According to the sixth aspect of the present invention, the operator or the like sets the tag piece on the first holding member, and then the tag piece is transferred from the first holding member to the second holding member. The tag piece is conveyed toward the strip-shaped portion by the second gripping member and is joined.

Further, as shown in FIG. 9, for example, when a pair of left and right sheet-like members Q1 and Q2 are continuously processed in the order of left and right, the sheet-like member Q1 on the left to the sheet-like member Q1 on the left side. When the processing is performed in this order, the mounting interval between the two tag pieces may be small (interval L2), and the time margin of the mounting processing may be small. However, the first gripping member to the second gripping member may be reduced. By the delivery process to the tag piece, a buffer effect is obtained during the processing from the setting of the tag pieces to the attachment, and it is possible to give a margin to the time to set the tag pieces even when the attachment interval of the tag pieces is small. .

That is, after attaching the tag piece to the rear side of the second sheet-like body Q2 in FIG. 9, the next sheet-like body Q1 is attached.
In the case of attaching the tag piece to be attached to the second sheet-like body Q2, for example, the attachment interval of the two tag pieces becomes small (interval L2) and the time margin of the attachment process also becomes small. The tag piece is set to the first gripping member at an early timing (for example, when the second sheet-shaped body is set to the apparatus), and then the tag piece is quickly set to the first piece.
By passing from the gripping member to the second gripping member, and waiting the second gripping member until the attachment timing of the tag piece in the second sheet state Q2, the first gripping member is in a free state at an early stage (that is, The next tag piece can be accepted). For example, the rear end of the second sheet-shaped body Q2 is sent to the transport mechanism, and the first gripping member can be set in a free state at the stage of setting the next third sheet-shaped body Q1 in the apparatus. I can.

Therefore, even when the tag pieces are attached to the plurality of sheet-like bodies in the order of the front side, the rear side, the front side, and the rear side, the operator or the like constantly has a margin to set the tag pieces. Therefore, the workability is improved.

[0031]

A clip moving mechanism 40 that functions as a first moving mechanism and a second moving mechanism that are moved toward
Of these, the second gripping mechanism 30 and the clip moving mechanism 40 constitute a tag piece arrangement mechanism.

Regarding the left and right transport mechanisms 2 and 3,
Since it is disclosed in detail in the prior art publications cited in the prior art, the description is omitted. Further, since the present invention has little relation to the centering process, illustration and description of the configuration related to the centering process are omitted, but the folding device of this embodiment is disclosed in Japanese Patent Application No. 2001-50508. Similarly, a core material guide, a lock sewing machine for centering processing, and the like are provided.

In FIG. 2, the first name tag is set.
The detailed view of a holding mechanism is shown. FIG. 7A is a plan view showing a state in which the clip is fixed, and FIG. 6B is a plan view showing a state in which the clip is detached and conveyed to the back of the apparatus.

The first gripping mechanism 10 includes a clip 11 serving as a gripping member for gripping the name tag NT and a name tag NT.
Mounting member 12, which supports the name tag NT when setting, the switch 13 for opening and closing the clip 11, the clip 11
2 includes a drive device 14 (a solenoid, an air piston, etc.) for opening and closing, and a drive mechanism for opening and returning the clip 11 from the setup position in FIG. 2A.

The clip 11 is designed to be laid sideways when the opening / closing part is fixed at the setup position, and is laid down when it is released from the setup position.

By operating the switch 13 while the clip 11 is fixed at the setup position shown in FIG. 2A, the mouth of the clip 11 is opened and closed, and the name tag is sandwiched and set in the clip 11. The name tag is set by folding one piece of cloth in two and sandwiching the portions where both ends are folded with the clip 11. Further, the setting of the name tag is usually performed together when one curtain body cloth is set in the device. Then, as soon as the name tag and the curtain body material are set and the left and right transport mechanisms 2 and 3 are operated by the operator's pedal operation or the like, a control signal is output from the control circuit (not shown), and the clip 11 is released from the fixed state. After being released, it is conveyed along the rail 20 from the front side of the apparatus to the rear side. After the clip 11 reaches the second gripping mechanism 30 and delivers the name tag, the clip 11 is returned to the first gripping mechanism 10 along the rail 20, and the clip 11 is returned to the setup position again.

FIG. 3 is a side view showing parts of the second gripping mechanism 30 and the moving mechanism 40.

As shown in FIGS. 1 and 3, the second gripping mechanism 30 includes an arm member 31 formed in a key shape,
A clip 31a as a second gripping member, which is provided at the tip of the arm member 31 and grips a name tag, and a clip 1
Clip the name tag that has been grasped and transported to
The introduction guide 32 that is introduced into the inside and the introduction guide 32 that abuts on the clip 11 that has moved along the rail 20
There is provided a piston cylinder 33 or the like which is stopped or passed at the position.

The arm member 31 is provided with a driving device (for example, a solenoid or an air piston) (not shown) for opening and closing the clip 31a. The arm member 31 is supported so as to be rotatable about the shaft 41a in FIG. 1 by 180 degrees and movable in the Y direction in FIG. 1 (the longitudinal direction of the shaft 31b).

The clip moving mechanism 40 includes the second gripping mechanism 3
The rotation driving mechanism 41 is a second moving mechanism that rotates the 0 arm member 31, and the front-back driving mechanism 42 is a first moving mechanism that moves the arm member 31 back and forth in the Y direction of FIG. It

The rotary drive mechanism 41 comprises a rotary shaft 41a, a cam member 41b (FIG. 5) fixed to the rotary shaft 41a and brought into contact with the arm member 31, and a drive motor 41c for rotationally driving the rotary shaft 41a. To be done. And the rotating shaft 41
When a is rotationally driven, the cam member 41b pushes the arm member 31 to rotate the arm member 31.

The front-rear drive mechanism 42 uses different mechanisms for moving the arm member 31 forward (forward in the Y direction) and moving the arm member 31 backward (reverse direction in the Y direction). You can get it. The mechanism for moving forward is configured to drive the arm member 31 by converting the rotational movement of the rotary shaft 43 into the back-and-forth movement of a support body that supports the arm member 31 via a link mechanism such as a rack or a pinion. Has been done. In addition, this mechanism,
Although not shown in detail, a link mechanism (gear 44 or pulley 4) that guides power from the upper conveyance pulley of the left conveyance mechanism 2
3a) and a clutch mechanism provided in the middle of the link mechanism and capable of switching power transmission or non-transmission. The mechanism for moving backward is the arm member 31 by a backward drive device such as a piston cylinder (not shown).
It directly retreats the support.

When the clutch mechanism is switched to the power transmission state, the transport motion of the left transport mechanism 2 is transmitted to the rotary shaft 43 and the arm member 31 is pushed forward. Therefore, in this state, the arm member 31 moves forward in synchronization with the carrying movement of the left carrying mechanism 2. That is, if the speed of the transport movement changes or stops, the speed of the arm member 31 also changes or stops. Further, when the transport mechanism carries out the intermittent feed motion in accordance with the motion of the lockstitch sewing machine 4, the arm member 31 is also intermittently moved in synchronization with it. Further, the ratio of the movement amount of the transport movement and the movement amount of the arm member 31 is set to 1: 1.

Further, when the clutch mechanism is switched to the power non-transmitting state and the backward drive device is driven, the arm member 31 is pulled back backward.

In this embodiment, the arm member 3
In order to synchronize the movement of 1 (that is, the movement of the clip 31a as the gripping member) and the movements of the transport mechanisms 2 and 3, the configuration of transmitting the movement of the transport mechanism 2 to the arm member 31 is adopted. The movement of the arm member 31 and the transport mechanism are achieved by moving the arm member 31 forward by an electric drive device (motor or the like) and synchronizing the drive device with the drive motor of the transport mechanism 2 by electrical control. It is also possible to synchronize with the transporting movement of 2.

Next, the operation of the name tag carried by the clip 11 of the first gripping mechanism 10 being transferred to the clip 31a of the second gripping mechanism 30 and being sewn to the strip portion of the curtain body cloth will be described. To do.

FIGS. 4 and 5 are flow charts (A) to (5) for explaining the operation of the first clip and the second gripping mechanism of the first gripping mechanism.
(E) is shown.

As shown in FIG. 4A, the second gripping mechanism 3
When the name tag is conveyed by the clip 11 of the first gripping mechanism 10 with the clip 31a of 0 being in the tag introduction position, the clip 11 remains as it is.
Move to the position above and stop. The name tag grasped by the clip 11 thereby passes through the introduction guide 32 and is inserted between the clips 31a. As shown in FIG. 8, since the name tag is folded in two and the cloth end side is gripped by the clip 11, the portion protruding from the clip 11 is in a swelled state, but the introduction guide 32
As a result, this bulge is narrowed, so that it can be properly inserted between the clips 31a.

Then, when it is confirmed by a sensor (not shown) that the clip 11 has reached the upper position of the clip 31a, the driving device for opening and closing the clip 31a operates to close the clip 31a and grasp the name tag. Then, the driving device for opening and closing the clip 11 is activated to open the clip 11. Thereby, the name tag is changed from the clip of the first gripping mechanism 10 to the clip 31a of the second gripping mechanism.
Is handed over to.

When the name tag is delivered, as shown in FIG. 4B, the drive motor 41c of the rotary drive mechanism 40 is immediately actuated to rotate the rotary shaft 41a and the cam member 4.
1b is rotated. As a result, the arm member 31 is rotated so that the clip 31a is closer to the front side of the apparatus than the needle drop position of the lockstitch sewing machine 4 and the gap between the conveyor belts 2B and 3B of the left and right conveyor mechanisms 2 and 3 is formed. It is sent to a certain point. When viewed in the height direction, the tip of the clip 31a is stopped at a height position where it does not overlap the conveyor belts 2B and 3B, and the portion of the name tag protruding from the clip 31a comes to a height position where it overlaps the conveyor belts 2B and 3B. It is like this.

At this time, the air blow supply mechanism 50
By abruptly sending air from above diagonally toward the gap between the transport mechanisms 2 and 3, even if there is only a slight gap between the transport mechanisms 2 and 3, the protruding portion of the name tag is the transport mechanism 2 and 3. It is surely sent to this gap without being stuck.

Further, the clip 11 of the first gripping mechanism 10
Starts to retract toward the setup position almost at the same time as the arm member 31 rotates, and is returned to the setup position as it is.

When the clip 31a of the second gripping mechanism 30 is sent to the center of the left and right transport mechanisms 2 and 3, the clip 31a
4a waits at the position of FIG. 4 (B) until the body tags are transported by the transport mechanisms 2 and 3 and the name tag attachment position is reached. The folding device detects the introduction of the sheet-like body and counts the amount of conveyance movement of the left and right conveying mechanisms 2 and 3 to find out how many millimeters from the starting end of the sheet-like body is in the conveying path. Is recognizable. And
By this counting process, the system waits until the attachment position of the name tag overlaps the standby position of the clip 31a, and when this attachment position overlaps the standby position, the clutch mechanism of the front-rear drive mechanism 42 changes from the power non-transmission state to the transmission state. Can be switched to.

As a result, the arm member 31 having the clip 31a slides forward in synchronization with the carrying movement of the carrying mechanism 2 and at the same speed as the carrying moving speed of the carrying mechanism 2. When the body material is approaching the needle drop position of the lockstitch sewing machine 4, the transporting movement of the transporting mechanism 2 is intermittently synchronized with the movement of the sewing machine needle 4a, so that the clip 31a is also intermittently synchronized with it. It is considered as exercise.

Then, by the transport motion of the transport mechanism 2 and the arm member 31 advancing as it is, the name tag grasped by the clip 31a passes through the needle drop position while being sandwiched between the folded portions of the curtain body cloth, It is sewn together with the curtain fabric. Then, as shown in FIG. 4C, when the name tag gripped by the clip 31a passes the needle drop position, the driving device of the clip 31a operates to open the clip 31a and release the name tag.

Even if the operator releases the operation pedal (not shown) to temporarily stop the process while the name tag is being sewn and then restart the process, the transport mechanism 2,
Since the arm member 31 also stops and restarts in the same manner as the stop and restart of 3, the beautiful finish can be obtained without any problem in mounting the name tag.

Then, at the position shown in FIG.
As soon as a is opened and the name tag is opened, the drive motor 41c of the clip moving mechanism 40 is actuated and the rotary shaft 4
1a and the cam member 41b are rotated. Thereby,
As shown in FIG. 5D, the arm member 31 rotates and the clip 31a is moved to the side where the introduction guide 32 and the rail 20 are located. At this time, since the arm member 31 is fed to the front, the arm member 31 is placed further away from the introduction guide 32.

In the first gripping mechanism 10, the second gripping mechanism 30
When the arm member 31 of FIG. 4 is in the position of FIG. 4 (B) to the position of FIG. 5 (D), the next name tag is set, and further, the clip 11 is removed from the setup position, It is in a state of being sent forward along the rail 20.

Here, if the clip 11 advances to the position where it has passed through the introduction guide 32, and then the arm member 31 returns, the name tag between the clips 11 is placed between the clip 11 due to the bulge of the name tag held by the clip 11. Difficult to insert into. In order to prevent this, the piston 33a of the piston cylinder 33 extends and the clip 11
And the clip 11 is placed in front of the introduction guide 32 or at a position where the name tag is inserted in the introduction guide 32.

Then, as shown in FIG. 5 (E), the arm member 31 of the second gripping mechanism 30 is pulled to pull the clip 3 thereof.
After 1a is returned to the tag introducing position, the piston 33 is pulled and the clip 11 can be moved to the tag introducing position. Then, the next name tag is passed. After that, it is repeated.

FIG. 6 is a front view of the operation panel showing the name tag attachment setting screen displayed.

The operation panel unit 7 is wire-connected to the control circuit of the folding device, and has, for example, the length of the fold-over width (the vertical width of the folded portion), the total length from the front end to the rear end of the body cloth ( (Original width) and various sewing parameters such as the interval between the stitches of the lockstitch sewing machine 4 and various tag and position settings such as name tag attachment positions.
Further, when an error or the like occurs in the operation mode, the notification of the error or the notification of the error location is displayed.

Of these, the setting contents relating to the attachment of the name tag will be described.

As for the setting related to the attachment of the name tag, as shown in the display screen of FIG. 6, the setting of the attachment position such as how many millimeters from the edge of the body material the name tag is attached, and a plurality of body material are attached. There is setting of attachment pattern of name tag in case of continuous processing.

For setting the attachment pattern, four patterns "S (start), E (end), SE, none" can be selected. Further, among the “SE” patterns, the “SE” pattern in which “S” is selected and the “SE” pattern in which “E” is selected can be selected.

Of these attachment patterns, the "S" pattern is a pattern in which the name tag is constantly attached to the front side of the body cloth. Therefore, in this pattern, the name tag is attached from the tip of the body cloth to the length position designated by the length setting of the attachment position. On the contrary, the “E” pattern is a pattern in which the name tag is constantly attached to the rear end side of the body cloth. In this pattern, the name tag is attached from the rear end of the body material to the length position designated by the length setting of the attachment position. The “SE” pattern is a pattern in which mounting on the front side and mounting on the rear side are alternately switched one by one. Further, the "SE" pattern in which "S" is selected is a processing pattern started from the front side, and the "SE" pattern in which "E" is selected is a processing pattern started from the rear side. “None” means that the tag is not attached.

Of these mounting patterns, the "SE" pattern is an effective pattern when one set of left and right curtains is continuously processed in the order of left, right, left and right. In addition,
When the "SE" pattern is set, the length of the attachment position when attaching the name tag to the front side of the body fabric and the length of the attachment position when attaching the name tag to the rear side of the body fabric are different from each other. It may be configured to be settable.

As described above, according to the sheet-like folding apparatus of this embodiment, the name tags can be automatically joined together with the folding of the curtain, and the second gripping can be performed. By controlling the movement timing of the clip 31a of the mechanism 30, it is possible to easily control at which position in the longitudinal direction of the upper edge portion of the body cloth the tag piece is attached.

Further, in the folding-over process, the curtain body material is conveyed in an intermittent feed in synchronization with the movement of the needle 4a of the lockstitch sewing machine 4, and the name tag is also fed in synchronization with this. Therefore, the name tag can be attached neatly without any gap between the body material and the name tag. Similarly, when the name tag is attached, even if you stop the folding operation or change the processing speed, the name tag feed also stops or changes the speed in synchronization with it. Does not occur. Therefore, the operator can concentrate on the processing of the cover-up processing by stopping the processing or changing the processing speed when necessary without being distracted by the attachment of the name tag.

Further, the clip 31a of the second gripping mechanism 30 which grips and conveys the name tag continues gripping and conveying until the entire width of the name tag is sewn into the body material, so that the name tag can be reliably prevented from being improperly attached and the finished product. A beautiful name tag can be attached with high reliability.

Further, by setting the "SE" pattern in the setting item of the name tag attachment pattern via the operation panel unit 7, the attachment position of the name tag is switched to the front side and the rear side of the body cloth one by one. When processing one set of right and left curtains in the order of left, right, left and right, it is not necessary to change the setting position of the name tag for each sheet, and the operability can be improved.

Further, the clip 11 of the first gripping mechanism 10 is sent to the back of the apparatus and the clip 31 of the second gripping mechanism 30 is sent.
By passing the name tag to a, and then the clip 31a of the second gripping mechanism 30 moves the name tag from between the transport mechanisms 2 and 3 toward the needle drop position of the sewing machine 4,
Since the name tag is configured to be sewn to the curtain body material, the worker can set the name tag on the front side of the device for introducing the body material, which improves workability.

As described in the problem to be solved by the invention, when a pair of left and right curtains are processed in the order of left, right, left and right, as shown in FIG. When machining in the left-right order, it becomes long (interval L1), and when machining in the right-left order, it becomes short (interval L2). Therefore, when processing in the order of right and left, the time margin of the attachment processing of the name tag becomes small, but by passing the name tag from the first gripping mechanism 10 to the second gripping mechanism 30, the processing from setting of the name tag to attachment can be performed. A buffer effect can be obtained in the meantime, which allows a margin to be set in the time for setting the name tag (specific explanation is given as a means for solving the problem). Therefore, workability is improved because the operator always has time to set the name tag.

The present invention is not limited to the sheet-like folding device of the above-described embodiment. For example, the clip 31a of the second gripping mechanism 30 moves in the vicinity of the transport path of the transporting means 2, 3 while gripping the name tag, and the name tag has all needle drop points before the needle drop point of the lockstitch sewing machine 4. Although it is assumed that the name tag reaches the needle drop point and is slightly sewn, the clip 31a may be opened to open the name tag, or the name tag may be opened before reaching the needle drop point. If the name tag is properly fixed by being sandwiched between the folded portions, the clip 31a may open the name tag at the fixed stage before reaching the needle drop point.

Regarding the configuration and control operation for transferring the name tag from the clip 11 of the first gripping mechanism 10 to the clip 31a of the second gripping mechanism 30, for example, a guide for smoothly inserting the inflated name tag into the clip 31a is used. By providing, it becomes unnecessary to perform standby control of the clip 11 as shown in FIGS. 4D and 4E.
Various changes are possible.

In addition, the type of sewing machine that sew together the folded body material, the first gripping mechanism 10 and the second gripping mechanism 3
0, and a configuration in which the clip 11 of the first gripping mechanism 10 is transported to the second gripping mechanism 30, and the clip 31 of the second gripping mechanism 30 is moved to the vicinity of the transport path of the strip-shaped portion, or the strip-shaped portion is transported. Clip moving mechanism 40 for moving in synchronization
The configurations specifically described in the above embodiments can be appropriately changed within the technical scope of the present invention.
