Detailed Description of the Invention

[0001]

INDUSTRIAL APPLICABILITY The present invention is capable of edging an edge connecting any two adjacent corners of a rectangular cloth such as a wrapping cloth, a sheet, a bed cloth or a hanging cloth. The present invention relates to a framing device for square shaped cloth.

[0002]

2. Description of the Related Art For example, in a laundry factory or the like, a rectangular cloth having a relatively large edge width such as sheets is pressed by a rotary roll type cloth product pressing machine or folded by a conveyor type cloth product folding machine. Although the dribbling work is performed, when supplying the rectangular cloth to the processing device (hereinafter, simply referred to as a press machine), the edge connecting the two adjacent corners of the rectangular cloth is straightened. Need to be stretched (marginal). Conventionally, the edging work of such a square cloth is performed by two workers holding and extending two adjacent corners of the square cloth, respectively, or by one worker. Had to hold each corner and spread both hands as far as possible.

The applicant of the present invention, as disclosed in Japanese Patent Laid-Open No. 4-9198, uses a holding means to hold one corner of a rectangular cloth and a part of the edge adjacent to the corner. We have proposed a square-shaped cloth edging device that can automatically carry out the edging of a square-shaped cloth by simply holding it.

As shown in FIG. 9, this known (Japanese Patent Laid-Open No. 4-9198) quadrilateral edging device holds two left and right holders provided on a movable body 2 which is movable back and forth in a gantry front and rear direction. With the means 22 and 23 holding one corner of the rectangular cloth Y and the edge adjacent thereto, the moving body 2 is drawn in from the cloth mounting position P ′ by the chain line 2 ′. The conveyors 5A to 5E are independently driven in the forward and reverse directions by the detection signals from the side edge detectors 71A to 71E that detect the presence or absence of the side edges of the cloth. The one side edge portion Yb of the square-shaped cloth on each of the conveyors is aligned (lined out) linearly. As the holding means 22 and 23, an automatic holding device called an air chuck is used, and an edge portion (including one corner portion) of a rectangular cloth is set to a predetermined length (for example, 30 to 4).
By applying the two edge portions to the respective holding means 22 and 23 in a state of being stretched by about 0 cm), the edge portions of the cloth can be automatically held by the respective holding means 22 and 23. There is. . Also, in this way, the conveyor 5A-
The square-shaped cloth Y edging on 5E is discharged to the next process side (for example, the press process side) by the discharging device as indicated by arrow A, with the rimmed side edge portion Yb as the leading side. . In the known edging device Z '(Fig. 9), the cloth mounting work position R'provided in the extension line direction of the moving body advancing and retracting direction.
The work for holding the edges of the cloths by the holding means 22, 23 is performed. Also, this cloth mounting work position R '
A large number of rectangular cloths to be processed are carried on the carriage X. This movable carriage X has a considerably large area, and a considerably large work space is required at the working position R'of the cloth apparatus.

By the way, in a large-scale laundry factory, when a plurality of square-shaped cloth edging devices Z'as described above are arranged in parallel, the extended square-shaped cloth Y'is downstream in the discharge direction. Due to the fact that a press machine or the like is installed in the above, the respective edging devices Z'and Z'are arranged so that the discharge directions of the rectangular cloth Y'are parallel to each other. As described above, when the edging devices Z ′ and Z ′ are arranged side by side in a state in which the ejected directions of the square-shaped cloths Y ′ are parallel to each other, the movable carriage X is moved to the cloth mounting work position R ′. Since it is necessary to secure a work space for installation (on which cloth to be treated is placed), it is necessary to provide a considerable space W'between the adjacent edging devices Z ', Z'.

[0006]

However, in the case of edging a rectangular cloth having a relatively large edge width as in the above-mentioned conventional example, two workers are required to remove two corners adjacent to each other. In the case of gripping / extending, respectively, it is necessary for one operator to search for another corner adjacent to the gripped corner and grip it, and then to stretch the edge by both. There were two people involved in the rimming work, and the efficiency of the rimming work was poor. In addition, when the edging work of the square-shaped cloth is performed by one worker, the width of the edging is large, so that it is very difficult to find two adjacent corners and grasp each with both hands. However, there is a problem in that both hands having respective corners must be widened to extend the edge, and a great amount of labor is required for the edge extension work.

Further, when the known edging device Z'shown in FIG. 9 is used, the edging work of the rectangular cloth can be performed relatively easily, but a plurality of the edging devices Z'are used in parallel. In this case, it is necessary to secure a large space W'between the edging devices Z'and Z ', and there is a problem that the floor area utilization efficiency in the factory is poor.

In view of the above-mentioned problems of the prior art, the invention of the present application is capable of edging a square-shaped cloth with only one operator and with a simple operation. When two or more machines are installed side by side in the factory, the utilization efficiency of the floor area can be improved and the framing work of the square cloth can be performed more reliably. The purpose is to provide a device.

[0009]

SUMMARY OF THE INVENTION A square cloth edging device according to the invention of claim 1 of the present application comprises a frame having a front and rear length longer than the length of the long side of the square cloth to be treated, and the frame of the frame. A movable body that can move back and forth in the longitudinal direction of the gantry at a position near the upper part, and two holding means provided on the movable body and capable of detachably holding two edges of one edge of a rectangular cloth with a space therebetween. A moving body drive device for moving the moving body forward and backward within a range from a cloth delivery position near the front part of the gantry to a cloth pulling position near the rear part of the gantry; A mounting table that can support the rectangular cloth from below when the moving body retracts while holding the position, and a part of the mounting table described above, which is oriented in a horizontal orthogonal direction to the moving body moving direction. Installed and the normal and reverse of the conveyor A conveyor drive device capable of running in a direction, a predetermined position on the conveyor, a side edge detector for detecting whether or not a side edge of a rectangular cloth is located, and one side on the mounting table. Discharging the square-shaped fabric whose edges are linearly edged out of the machine body in a direction orthogonal to the moving body advancing / retreating direction with the edged side edges being the leading side. And a temporary holding means for temporarily holding two positions at predetermined intervals in the horizontal direction at the edge of the cloth, in addition to the holding means of the moving body, in the front part of the gantry. Further, one side surface orthogonal to the cloth discharging direction of the discharging device in the front part of the gantry is set as a cloth mounting work position, while each of the temporary holding means stands by at the cloth mounting work position and the cloth transfer position. Horizontal with respect to the position corresponding to each holding means It is characterized by comprising a position changing device allowed to angle 90 ° displaced.

According to a second aspect of the present invention, in the rectangular cloth edging device of the first aspect, the cloth delivery position is provided at a height position substantially the same as the entire length of the cloth to be processed, and the position is changed. The device displaces each temporary holding means in a height range from a low height position which is a working height for temporarily holding the cloth edge portion to each temporary holding means to a height position of the cloth delivery position. The feature is that it is obtained.

[0011]

The operation of the present invention will be described with reference to the method of using this rectangular cloth edging device. According to the edging device of the first aspect of the present invention, the rectangular cloth to be edged is attached to this edging device. At the time of supplying, the moving body is first advanced to the cloth delivery position on the front part of the gantry, and each temporary holding means is orthogonal to the cloth discharging direction (parallel to the moving body moving direction).
Face the cloth attachment work position on one side. In that state, one worker searches for an arbitrary one corner of the square cloth that has been dried by a dryer (rolled state) and adjoins the corner and the corner. Each temporary holding means holds an appropriate position of the edge (for example, a position separated from the corner by about the shoulder width of the person). At this time, the cloth edges held by the two temporary holding means are stretched.

Next, when the temporary holding means holds two edges of the rectangular cloth at the cloth mounting position, each position of the temporary holding means holds the cloth edge by the position changing device. The temporary holding means is displaced from the cloth mounting operation position by an angle of 90 ° in the horizontal direction so that the temporary holding means correspond to the holding means waiting at the cloth delivering position. According to the second aspect of the invention, the position changing device acts so as to move the temporary holding means holding the cloth edges while moving them in the horizontal direction, which will be described later. Then, the cloth edges held by the temporary holding means are delivered to the holding means at the cloth delivering position. For the sake of convenience, in the following description, the edge portion of the rectangular cloth held by the two holding means is referred to as a holding edge portion, and the edge portion opposite to the holding edge portion is referred to as an end edge portion. The side edge portion on the side of the holding means that holds the cloth corner portion between the edge portion and the end edge portion will be referred to as an edge side edge portion.

Subsequently, when the edge of the cloth is held by each holding means on the side of the moving body (one holding means holds the corner of the cloth), the moving body driving device moves (retracts) the moving body backward, The lower surface of the hanging portion of the rectangular cloth has a contact resistance with respect to the front edge of the mounting table and is sequentially drawn rearward. At that time, due to the contact resistance, the rectangular cloth is pulled in while being stretched in the longitudinal direction of the gantry.

When the moving body retreats, the square-shaped cloths are sequentially drawn toward the back of the gantry, but when the side edge detector does not detect the existence of cloths, the conveyor drive device is triggered by the signal. Then, the conveyor is run from the holding means side holding the cloth edge to the holding means side holding the cloth corner, and conversely the side edge detector detects the presence of cloth. In this state, the signal causes the conveyor drive device to move the conveyor from the holding means side holding the cloth corner portion to the holding means side holding the cloth edge portion. Then, from this, the side edges of the rectangular cloth placed on the conveyor are positioned substantially linearly within the width of the reaction region of the side edge detector. Then, when the rectangular cloth is pulled over the loading table over the entire length, the holding of the cloth corner portion and the cloth edge portion by both holding means is released, and the rectangular cloth is placed on the mounting table on the edge side. It is placed with the side edges extending linearly. Then, the square-shaped cloth with the rim is
The discharge device discharges the cloth to the next process (for example, press process) side with the edge portion on the rimming side being the leading side.
After that, if the temporary holding means, the moving body, and the like are set to the initial state, the next edging operation of the rectangular cloth can be performed.

As described above, according to the rectangular cloth edging device of the invention of claim 1, when edging from the rolled rectangular cloth, one corner is formed at the cloth mounting work position. Only by holding each of the temporary holding means at a proper position of the edge portion adjacent to it, the process until the edged square-shaped cloth is discharged to the outside of the machine body can be automatically performed. Further, since the cloth mounting work position is provided on the surface orthogonal to the discharging direction of the edged cloth, when a plurality of rectangular cloth edging devices are arranged in parallel, the cloth discharging direction is set. Even if they are installed parallel to each other, it is not necessary to widen the interval between the edging devices.

Further, in the edging device according to the second aspect of the present invention, when both the temporary holding means are displaced from the cloth loading operation position to the cloth delivery position by the position changing device, the both temporary holding means. The cloth held in the whole is supported in a substantially suspended state, and the rolled cloth is linearly stretched (unraveled) by its own weight. Therefore, in the subsequent cloth retracting operation by the moving body, the cloth can be sequentially and smoothly drawn onto the mounting table.

[0017]

According to the rectangular cloth edging device of the present invention, only two edge portions (one corner portion) of the rectangular cloth to be processed are respectively held by the two temporary holding means. Thus, the square-shaped cloth can be discharged in a state where the square-shaped cloth is framed, and the framing work of the square-shaped cloth can be easily performed. Further, in this edging device, the cloth mounting work position is provided on one side surface orthogonal to the cloth discharging direction, so that a plurality of edging devices are arranged side by side so that the cloth discharging directions are parallel to each other. In the case of installation, there is no problem even if the respective edging devices are installed close to each other, so that there is an effect that the floor area can be used efficiently.

Further, in the rectangular cloth edging device according to the second aspect of the present invention, when the cloth held by the temporary holding means is displaced to the cloth transfer position at the cloth mounting operation position, the cloth is moved. Since the whole of the class is supported almost in the air, even if the square shape cloth is initially rolled, the cloth can be smoothly and sequentially placed on the mounting table when the cloth is drawn in by the moving body. As a result, the cloth can be pulled in, and thus the edging work of the cloth edge portion can be reliably performed.
