(Operation) The operation of the present invention will be described in relation to the method of using the rectangular cloth edging device.

According to the edging device of the first aspect of the present invention, when the rectangular cloth to be edged is supplied to the edging device, the moving body driving device first moves the moving body to the front working side. deep. In that state, for example, one corner portion of the square cloth that has been dried by a dryer (rolled state) is searched for, and the corner portion and an edge portion adjacent to the corner portion (for example, The position where the person's shoulder width is separated from the corner) is held by the holding means. At this time, one corner may be first gripped by the gripping means, and then the edge part adjacent to the corner may be gripped by the gripping means, or one of the rectangular cloths may be gripped. It is also possible that the corner portion and a position on the edge portion adjacent to the corner portion, which is separated from the corner portion by about the shoulder width of the person, are grasped / extended by both hands in advance, and then the grasping means simultaneously grasps.

As described above, in a state in which one corner and a part of the edge portion adjacent to the one corner are gripped by the gripping means, the gripping portion of the rectangular cloth by the gripping means is at a high position, and the other portion is held. Hangs down due to its own weight, and the entire square-shaped cloth is stretched and expanded to some extent. For the sake of convenience, in the following description, the edge of the rectangular cloth that is held by the holding means is referred to as a holding edge, and the edge facing the holding edge is referred to as an end edge. The side edge of the cloth corner grasping side between the grasping edge portion and the end edge portion is referred to as an edge side edge portion.

Next, when the moving body is moved backward (backward) by the moving body drive device while holding the rectangular cloth by the gripping means, the lower surface of the hanging portion of the rectangular cloth is placed on the mounting table. It has a contact resistance with the front edge of the and is drawn in the rearward direction. At that time, due to the contact resistance, the rectangular cloth is drawn in while extending in the front-rear direction, and the cloth extension protruding forward at the front edge of the mounting table is an extension line of the moving body forward and backward direction between the gripping means. Since it is located at a position where it is vertically overlapped with each other, the drawn rectangular cloth extends over both the left and right sides of the cloth expansion portion. As a result, the edge side edges of the rectangular shaped fabric are sequentially extended in the lengthwise direction, and the cloth width portion between the edge side edges and the portion in contact with the cloth extension portion is laterally extended. It will be expanded. Then, in this state, the moving body is further moved backward, so that the rectangular cloths are sequentially drawn to the rear side, and the entire length of the rectangular cloths is placed on the mounting table. After that, when the grasping of the cloth corner portion and the cloth edge portion by the gripping means is released, the rectangular cloth is placed on the mounting table in a state where the rimming side side edge portion is linearly extended,
In the square-shaped cloth, the edge portion on the edge side and the two corner portions on the edge portion side become clear. Then, if the square-shaped cloth with the edging is delivered to a press or the like, and then the moving body is set to the initial state, the edging work of the next square-shaped cloth can be performed.

The side edge portion detector 71 is for detecting the edge portion side edge portion Yb of the square shaped cloth Y at the conveyor installation portion when the square shaped cloth Y is pulled into the back side of the gantry.
In the embodiment, a photoelectric tube is used. In addition, in the first embodiment, the side edge detector 71 is the first belt 5 from the gantry front side of the conveyor 5 on the rear base plate 43.
The detection unit is installed in the gap S between the second belt 52 and the second belt 52 and directly above the position where the cloth corner gripping means 22 passes.

The end edge detector 72 employs a photoelectric tube in the first embodiment, and the end edge Yc of the rectangular cloth Y approaches the front end of the conveyor 5 on the platform 4. At this time, the presence of the end edge portion Yc is detected. That is, in this first embodiment, the end edge detector 72 passes through the rear base plate 43 in the vicinity of the front end of the conveyor 5 on the gantry front side and in the substantially middle portion in the left-right direction of the moving body 2. It is installed with the detection part facing up almost directly below the position.

Then, the side edge detector 71 and the end edge detector 72 respectively send the detection state or non-detection state of the cloth to the controller 10.

The controller 10 receives the signal from the side edge detector 71 and controls the conveyor drive device 6 to cause the conveyor 5 to travel in either the forward or reverse direction, and at the same time, the cloth from the end edge detector 72. Upon receiving the similar edge detection signal, the moving body drive device 3 is controlled to stop its operation. That is, when the side edge detector 71 is in the cloth non-detection state (when there is no cloth immediately above the side edge detector 71), the upper surface side of the conveyor 5 with respect to the conveyor drive device 6 is The side edge part is controlled to run in the pushing direction (from left to right direction), and when the side edge part detector 71 is in the cloth detection state, the upper side of the conveyor 5 is the side edge part with respect to the conveyor drive device 6. The control is performed so that the vehicle runs in the pull-in direction (from right to left). Therefore, the edge portion on the edging side of the portion of the rectangular cloth that comes into contact with the conveyor 5 is adjusted in small increments only in the left and right small areas with the detection position by the side edge detector 71 being sandwiched. become. Further, when the rectangular cloth Y is drawn into the back of the gantry together with the moving body 2, the end edge detector 72 is
First, when the rectangular cloth Y approaches the end edge portion detector from the cloth non-detection state, the cloth detection state is reached, and the moving body 2 is further retracted to end edge portion Yc of the rectangular cloth Y. When the cloth moves to the inner side of the position detected by the end edge detector 72, the cloth is not detected again. However, the controller 10 receives the signal from the end edge detector 72 transmitted at that time and the moving body is moved by the controller 10. The drive device 3 is controlled so as to be immediately stopped.

The method and operation of the rectangular cloth edging device of the first embodiment shown in FIGS. 1 to 5 will be described. This rectangular cloth edging device was dried by a dryer after washing in a laundry factory, for example. This is for stretching one of the four edges before feeding the rectangular cloth to a press or the like.
As shown in the figure, the moving body 2 is moved to the cloth gripping position near the front of the gantry, and the conveyor drive device 6 is activated. At this time, since the side edge detector 71 is in the cloth non-detection state, the conveyor drive device 6 causes the conveyor 5 to continuously run in the side edge pushing direction (from left to right). To drive.

In this state, an arbitrary corner C ₁ (FIG. 7) of the rectangular cloth Y to be processed is searched, and the corner C ₁ is grasped at the cloth gripping position P. The gripping means 22 grips the cloth edge gripping means 23 while gripping a part of an arbitrary edge portion Ya of the two edge portions continuous with the gripped corner portion C ₁ . At this time, the space between the corner C ₁ gripping portion by the cloth corner gripping means 22 and the edge gripping portion by the cloth edge gripping means 23 in the gripping edge portion Ya is appropriately extended.
When the gripping means 22 and 23 are made to grip the two points of the cloth edge, the two points are preliminarily gripped by the respective hands, and the two points are simultaneously gripped by the respective gripping means. 22 and 23 may be made to grip, but at that time, since the distance between the two gripping means 22 and 23 is set to about the shoulder width of the person, one corner C ₁ and its corner C ₁ This can be done with each edge gripping the edge portion at a position separated from C ₁ by about the shoulder width (for example, the position of the reference numeral Ya ′ in FIG. 7), and the handing work to the holding means 22, 23 side is easy. You can do it (without expanding your hands too much).

In this way, when the rectangular cloth Y is held at two points by each gripping means, the rectangular cloth Y is suspended at the front part of the gantry, and the moving body drive device 3 is moved in this state. When it is operated in the body retreating direction, the rectangular cloth Y suspended as shown in FIG. 4 is pulled toward the rear of the gantry together with the moving body 2. At this time, the square-shaped cloth Y
Of the hanging table 4 is pulled up onto the placing table 4 while having a contact resistance with the front edge portion of the placing table 4 (the front edge portion of the front base plate 41), and the rectangular cloth Y Is placed on the mounting table 4 while being extended in the front-back direction.

Further, when the rectangular cloth Y is pulled up on the mounting table 4, the cloth expansion portion (protruding portion) 42 of the front base plate 41 causes
The vicinity of the cloth expanding portion contact portion of the rectangular cloth Y is expanded in the left-right direction, and the side edge portion Yb to be framed can be surely exposed.

When the moving body 2 is retracted to some extent, and the end of the rectangular cloth Y near the advancing side contacts the upper surface of the conveyor 5, as shown in FIG. 4, for example, the side edge detector 71 is in the cloth non-detecting state. At this time (when the fabric side edge portion Yb is located on the left side of the detection position by the side edge portion detector 71).
Running in the side edge pushing direction (from left to right), the cloth portion in contact with the conveyor upper surface is moved to the side edge pushing direction side, and conversely, the side edge detector 7
When 1 is in the cloth detection state, the conveyor 5 is running in the side edge part retracting direction (from right to left direction), so that the cloth part in contact with the conveyor upper surface is moved to the side edge part retracting direction side. By sequentially repeating such an operation, the position of the cloth side edge portion Yb in contact with the upper surface of the conveyor 5 is adjusted in small increments in the left-right direction.

In this way, the cloth side edge portion Yb passing through the detection position by the side edge detector 71 comes to pass through a portion in a very small range in the left-right direction, and the moving body 2 is sequentially moved as the moving body 2 is retracted. It can be stretched in a substantially straight line parallel to the traveling direction. Then, when the moving body 2 moves further to the rear and the end edge detector 72 no longer detects the presence of cloth as shown in FIG. 5 (the cloth end edge Yc is detected as the end edge). Immediately after passing through the detection position by the container), the signal from the end edge detector 72 immediately stops the operation of the moving body drive device 3. At this time, the conveyor drive device 6 may be stopped at the same time.

Next, when the gripping by the gripping means 22 and 23 is released, the cloth edge portion Ya held by the gripping means 22 and 23 falls on the mounting table 4. In this state, the two corner portions C ₁ and C _{2 of the} edge portion Yb on the rimming side are linearly extended. In the first embodiment shown in FIGS. 1 to 5, the cloth edge gripping means 23 is a part of the edge Ya on the short side of the square cloth Y, Ya '(FIG. 7). Although the case where the cloth is gripped is shown, the cloth edge gripping means has a part of the edge on the long side (for example, Yb 'in FIG. 7).
Part) may be grasped. In that case, the side edge portion on the short side of the rectangular cloth Y (reference numeral Yc in FIG. 7).
Edge) will be framed.

As described above, when the edging device of the first embodiment is used, the rectangular cloth Y at the cloth gripping position P at the front of the gantry.
Only one corner C ₁ and a part of the edge portion Yb that is continuous with the _one corner portion C _{1 in} FIG. Will be able to. The square-shaped cloth Y thus edged may be supplied to a press or the like with the edged portion being the leading side.

Next, the square cloth edging device of the second embodiment shown in FIG. 6 will be described. In the edging device of the second embodiment, a plurality of ( A collective conveyor 50 is installed in which narrow width conveyors 5A to 5E (five in total) are sequentially juxtaposed side by side in the rack front-rear direction (moving body advancing / retreating direction). Each of the narrow conveyors 5A to 5E is arranged so as to be able to travel in a direction orthogonal to the moving body advancing / retreating direction, and the length in the front-back direction of the gantry in the collective conveyor 50 composed of the narrow conveyors is a square to be processed. The length of the cloth Y on the long side is substantially equal to or longer than that.

Each of the narrow conveyors 5A to 5E is made to travel in both forward and reverse directions by an individual conveyor drive device 6A to 6E.

Immediately above each of the narrow conveyors 5A to 5E, side edge detectors 71A to 71E for detecting whether or not a side edge of the cloth exists at a predetermined position on each of the narrow conveyors 5A to 5E respectively correspond. Has been installed. Each side edge detector 71A
To 71E (five in total) are fixed to the frame of the gantry 1 that is assembled in parallel with the moving body advancing and retreating direction, respectively, and one end portion in the traveling direction of each narrow width conveyor 5A to 5E (cloth cloth corner gripping). It is possible to detect whether or not there is a cloth side edge portion on the upper surface of the holding means side end portion). The narrow conveyors 5A to 5E are arranged such that the lines connecting the respective detection positions are straight.

The signals from the side edge detectors 71A to 71E are transmitted to the controller 10, respectively, and based on the signals, the controller 10 drives the conveyor of the narrow conveyor corresponding to the detection position of the side edge detector. Device (6
A to 6E) can be individually operated in either forward or reverse directions. That is, when the side edge detector (for example, the side edge detector 71A) is in the cloth non-detection state, the conveyor drive device 6A corresponding to the side edge detector 71A in the cloth non-detection state is set. , The narrow conveyor 5A
Is operated so as to run in the cloth pushing direction (to the right), and conversely, when the side edge detector (for example, the side edge detector of reference numeral 71A) is in the cloth detecting state, the cloth detecting state is detected. The conveyor drive device 6A corresponding to the side edge detector 71A is operated so that the narrow conveyor 5A travels in the cloth drawing direction (left direction). Thus, based on the signals from the side edge detectors 71A to 71E, the corresponding narrow width conveyors 5A to 5E
