Description

[0001]
[Industrial application fields]
The present invention relates to the handling of sheets of isotropic shape cloth in a laundry, and more particularly to an apparatus for supplying sheets of isotropic shape cloth after washing to a press such as a roll ironer.
[0002]
[Problems to be solved by the invention]
The present invention relates to a sheet isotropic cloth that can be used to rim an edge connecting any two adjacent corners in a sheet isotropic cloth such as a wrapping sheet, a sheet, a bed cloth, or a cloth. For example, in a laminating apparatus such as a laundry factory, a sheet-shaped isotropic cloth having a relatively large edge width such as a sheet is pressed by a cloth product pressing machine such as a roll ironer, or a conveyor-type cloth. When a sheet isotropic cloth is supplied to a processing apparatus that performs a folding operation using a product folding machine, an edge connecting two adjacent corners of the sheet isotropic cloth is extended linearly ( However, in the past, two workers have gripped the two adjacent corners of the sheet isotropic cloth.・ Do you extend Or one worker had been carried out by expanding as much as possible both hands were gripping the corners, respectively.
[0003]
However, as in the conventional example described above, when bordering a sheet of isotropic cloth having a relatively large edge width, two workers grip and extend two adjacent corners, respectively. It is necessary for one worker to search for and grip another corner adjacent to the gripped corner, and then to extend the edge between the two. The work efficiency was poor with the manpower.
[0004]
In addition, when one worker performs the edge alignment work for sheets of isotropic shape, the width of the edge is so large that the two adjacent corners are searched for and held with both hands. In addition, a large amount of time is required, and in order to extend the edge, both hands having the corners must be greatly expanded, and there is a problem that a great deal of labor is required for the edge extending operation.
[0005]
Accordingly, the applicant of the present application has provided a “sheet isotropic shape cloth bordering device” (Japanese Patent Publication No. 6-49119) that solves the above-mentioned problems, and this device is shown in FIGS. As shown in FIG. 6, the sheet is isotropically shaped cloth Y, such as a sheet, and has a considerable length in the front-rear direction by assembling the frame material back and forth, left and right, and up and down. A rectangular solid base 1 having a length (substantially longer than the total length of the long side of the sheet isotropic sheet Y to be processed), and a movable body that can move forward and backward in the longitudinal direction of the base at a position near the top of the base 1 2 and two positions at predetermined intervals in the horizontal left and right direction of the movable body 2, and one corner C1 of the sheet-shaped isotropic cloth Y and a part of the edge Ya adjacent to the corner C1 Cloth gripping means 22 and cloth edge which can be detachably gripped The pedestal 1 is provided with a holding means 23 for moving, a moving body drive device 3 for moving the moving body 2 forward and backward in a range from a cloth gripping position P at the front of the gantry to a cloth pulling position Q at the rear of the gantry. The loading table 4 that supports the sheet-shaped isotropic fabric Y drawn from behind the frame from below, the conveyor 5 that constitutes a part of the loading table 4, and the conveyor 5 can run in both forward and reverse directions. Conveyor driving device 6, side edge detector 71 for detecting the edge side edge Yb of the sheet-like isotropic cloth Y, and end edge for detecting the end edge Yc of the sheet-like isotropic cloth Y The unit detector 72 and the controller 10 that controls the operation of the edging device are the basic components.
[0006]
On the upper part of the gantry 1, one guide rail 11 is erected in the front-rear direction at an intermediate position in the left-right direction. The moving body 2 is guided by the guide rail 11 so as to be movable back and forth in the longitudinal direction of the gantry. As shown in FIG. 1, the moving range of the moving body 2 is such that the moving body 2 is in the front part of the gantry and the gripping means 22 and 23 can grip the sheet-shaped isotropic cloth Y. As shown in FIG. 5, the movable body 2 is in the rear part of the gantry and touches more than the range from the gripping position P to the cloth drawing position Q where the sheet-like isotropic cloth Y can be completely drawn on the mounting table 4. It has been determined.
[0007]
The moving body 2 is formed by providing drooping plates 21 and 21 bent downward on the left and right sides of a flat plate 20 having a length about the shoulder width of a person (a length of about 40 to 60 cm) in the left-right direction. . A gripping means (22, 23) for gripping cloths is attached to the front end of each of the hanging plates 21, 21 one by one. In this example, when viewed from the front side of the gantry, the gripping means 22 positioned on the right side is for gripping the cloth corner C1, and the gripping means 23 positioned on the left side is for gripping the cloth edge. Each gripping means 22, 23 employs a clip-type air chuck that operates with compressed air.
[0008]
The moving body drive device 3 includes sprockets 32 and 32 provided at the front and rear portions of the gantry 1, a chain of ends 33 installed between the sprockets 32 and 32, and one sprocket 32 in the forward / reverse direction. And a motor 31 that rotates in both directions. One end of the chain 33 is fixed to the moving body 2 after being wound around the front sprocket 32, and the other end of the chain 33 is fixed to the moving body 2 after being wound around the rear sprocket 32. Therefore, the moving body drive device 3 can move the moving body 2 forward or backward along the guide rail 11 by rotating the sprocket 32 clockwise or counterclockwise by the motor 31.
[0009]
The mounting table 4 is installed at a position slightly below the advance / retreat height position of each gripping means 22, 23. In the illustrated example, the mounting table 4 includes a front base plate 41 that is relatively short in the front-rear direction, a rear base plate 43 that is provided continuously at the rear edge of the front base plate 41, and a front base plate. It has a conveyor 5 capable of moving forward and backward in the horizontal and horizontal directions at a position near the rear end of the plate 41.
[0010]
In this embodiment, the conveyor 5 is configured by winding belts 52, 52... That are a total of four sets between a pair of left and right rolls 51, 51. An appropriate interval S is provided between the belts 52 and 52. In addition, the upper surface side traveling portion of each belt 52, 52... Is installed so as to travel in the vicinity of the upper surface side of the rear base plate 43. The conveyor driving device 6 is configured to be able to rotate the roll 52 on one side (left side) of the conveyor 5 forward / reversely via a sprocket and chain by a motor 61 capable of rotating forward / reversely.
[0011]
The side edge detector 71 is for detecting the edge side edge Yb of the sheet isotropic cloth at the conveyor installation portion when the sheet isotropic cloth Y is pulled into the gantry back side. In the illustrated example, a phototube is employed. Further, in the illustrated example, the side edge detector 71 is a gap between the first belt 52 and the second belt 52 from the front side of the conveyor 5 on the rear base plate 43. It is installed with the detection part facing upward in S and almost directly below the position where the cloth corner gripping means 22 passes.
[0012]
The end edge detector 72 employs a phototube, and when the end edge Yc of the sheet-shaped isotropic fabric Y reaches the front end of the conveyor 5 on the mounting table 4, the end edge detector 72. The presence of the edge Yc is detected. That is, the end edge detector 72 is detected on the rear base plate 43 in the vicinity of the front side end of the conveyor 5 and almost directly below the position where the substantially intermediate portion in the left-right direction of the moving body 2 passes. It is installed with the part facing up.
[0013]
Then, the side edge detector 71 and the end edge detector 72 transmit the detected state of the cloths or the non-detected state to the controller 10, respectively. The controller 10 receives the signal from the side edge detector 71 and controls the conveyor driving device 6 to run the conveyor 5 in either the forward or reverse direction, and the cloth from the end edge detector 72. In response to the end-of-class detection signal, the moving body driving device 3 is controlled to stop the operation.
[0014]
That is, when the side edge detector 71 is in the cloth non-detection state (when no cloth is present directly above the side edge detector 71), the upper surface side of the conveyor 5 is located with respect to the conveyor drive device 6. Control is made so that the vehicle runs in the side edge pushing direction (from left to right), and when the side edge detector 71 is in the cloth detection state, the upper surface side of the conveyor 5 is the side edge. The vehicle is controlled so as to travel in the pull-in direction (from right to left).
[0015]
Therefore, the edge-side edge of the portion of the sheet-like isotropic cloth that contacts the conveyor 5 is adjusted in small increments only in the left and right small ranges with the detection position by the side edge detector 71 interposed therebetween. Become so. Further, when the sheet-shaped isotropic cloth Y is drawn into the gantry back side together with the moving body 2, the end edge detector 72 first starts from the cloth non-detection state to the sheet or the like above the end edge detector. When the rectangular cloth Y is inserted, the cloth detection state is entered, and the movable body 2 further moves backward, and the end edge Yc of the sheet-like rectangular cloth Y moves to the back side from the detection position by the end edge detector 72. Then, the cloth non-detection state is entered again, but the controller 10 controls the mobile body drive device 3 to immediately stop operation upon receipt of the signal from the end edge detector 72 transmitted at that time.
[0016]
The use method and operation of the sheet isotropic shape cloth bordering device shown in FIG. 1 to FIG. 5 will be described. This sheet isotropic shape cloth bordering device is, for example, a sheet etc. that is dried in a dryer after washing in a laundry factory. This is to stretch one of the four edges before supplying the square-shaped cloth to a press or the like. To perform the edge alignment, first move it as shown in Fig. 1. The body 2 is moved to the cloth gripping position near the front of the gantry and the conveyor driving device 6 is operated. At this time, since the side edge detector 71 is in the cloth non-detection state, the conveyor driving device 6 drives the conveyor 5 to continuously run in the side edge pushing direction (from left to right). .
[0017]
In this state, an arbitrary one corner C1 (FIG. 6) of the sheet isotropic cloth Y to be processed is searched, and the corner C1 is gripped for the cloth corner at the cloth gripping position P. The means 22 is made to grip, and the cloth edge holding means 23 is made to hold a part of an arbitrary edge Ya of the two edges continuous to the held corner C1. At this time, the space between the corner C1 gripping part by the cloth corner gripping means 22 and the edge gripping part by the cloth edge gripping means 23 at the gripping edge Ya is appropriately extended.
[0018]
In addition, when the gripping means 22 and 23 each grip two points on the cloth edge, the two points are gripped in advance by the respective hands, and the two points are simultaneously gripped by the gripping means. The distance between the two gripping means 22 and 23 is set to be about the shoulder width of a person, so that one corner C1 and the corner C1. Can be carried out in a state where the edge of the position separated from the shoulder by the width of the shoulder (for example, the position of Ya ′ in FIG. 6) is gripped by each hand, and the handing operation to each gripping means 22, 23 is easy (both hands). Without greatly expanding
[0019]
In this way, when the sheet isotropic cloth Y is gripped at two points by each gripping means, the sheet isotropic cloth Y is suspended at the front of the gantry, and in this state, the mobile body is driven. When the apparatus 3 is operated in the moving body retracting direction, the sheet-like isotropic cloth Y suspended as shown in FIG. 4 is drawn together with the moving body 2 toward the rear of the gantry. At this time, the portion of the sheet isotropic fabric Y hanging from the front of the gantry is placed on the mounting table 4 while having contact resistance with the front edge of the mounting table 4 (the front edge of the front base plate 41). The sheet isotropically shaped cloth Y is placed on the mounting table 4 while being stretched in the front-rear direction by the contact resistance. Further, when the sheet isotropic cloth Y is pulled up on the mounting table 4, the cloth expansion of the sheet isotropic cloth Y is performed by the cloth expanding portion (protruding portion) 42 of the front base plate 41. The vicinity of the portion contact portion is expanded in the left-right direction, and the side edge portion Yb to be edged can be reliably exposed.
[0020]
When the movable body 2 is retracted to some extent, and the side closer to the advancing side of the sheet isotropic cloth Y comes into contact with the upper surface of the conveyor 5 as shown in FIG. In some cases (when the cloth side edge Yb is located on the left side of the detection position by the side edge detector 71), the conveyor 5 is running in the side edge pushing direction (from left to right), When the cloth part in contact with the upper surface of the conveyor is moved to the side edge pushing direction side, and the side edge detector 71 is in the cloth detection state, the conveyor 5 is pulled in the side edge part (from right to left). ), The cloth part that is in contact with the upper surface of the conveyor can be moved to the side edge pull-in direction side, and the portion of the part that is in contact with the upper surface of the conveyor 5 is sequentially repeated. Cloth side edge The b position so adjusted small increments in the horizontal direction.
[0021]
In this way, the cloth side edge Yb that passes through the detection position by the side edge detector 71 passes through a very small range in the left-right direction, and sequentially moves as the moving body 2 is retracted. It can be stretched in a substantially straight line parallel to the traveling direction. When the moving body 2 further moves rearward and the end edge detector 72 no longer detects the presence of the cloth as shown in FIG. 5 (the cloth end edge Yc is the end edge detector). Immediately after passing through the detection position, the operation of the moving body driving device 3 is immediately stopped by the signal from the end edge detector 72. At this time, the conveyor driving device 6 may also be stopped simultaneously.
[0022]
Next, when the gripping by the gripping means 22 and 23 is released, the cloth edge portion Ya gripped by the gripping means 22 and 23 falls on the mounting table 4. In this state, the space between the two corners C1 and C2 of the edge side edge Yb is extended linearly.
[0023]
In addition, in the sheet isotropic shape cloth edging apparatus shown in FIG. 1 to FIG. 5, the cloth edge portion gripping means 23 uses a portion Ya of the short side edge portion Ya of the sheet isotropic shape cloth Y. ′ (FIG. 6) is shown, but the cloth edge gripping means grips a part of the edge on the long side (for example, the portion of Yb ′ in FIG. 6). You may make it hold. In that case, the side edge part (edge part of the code | symbol Yc in FIG. 6) of the short side side of the sheet-like isotropic shape cloth Y comes to be edged.
[0024]
As described above, when this edging device is used, at the cloth gripping position P at the front part of the gantry, one corner C1 of the sheet-shaped isotropic cloth Y and a part of the edge Yb continuous therewith are connected. By simply gripping each of the gripping means 22 and 23, the sheet isotropic shape cloth Y can be trimmed automatically thereafter. The sheet-shaped isotropic cloth Y thus bordered may be supplied to a press or the like with the bordered portion leading.
[0025]
By the way, the “sheet isotropic cloth edging device” having the above-described structure is transferred to the press machine by the conveyor 5 when the sheet isotropic cloth Y which has been edged and dropped onto the mounting table 4 from the movable body 2. Therefore, if the sheet isotropic cloth Y is completely discharged from the conveyor 5 and the next sheet isotropic cloth Y is rimmed before the next sheet isotropic cloth Y, Are entangled with each other, so that it is necessary to wait for the next sheet isotropic cloth Y to be rimmed until the previous sheet isotropic cloth Y is completely discharged from the conveyor 5.
[0026]
[Problems to be solved by the invention]
Therefore, the present invention provides a sheet isotropic cloth Y which has been dropped on the conveyor 5 of the mounting table 4 in the previously provided “sheet isotropic cloth edging device”. It is an object of the present invention to provide a transfer device which is transferred to a conveyor so that the sheet-shaped isotropic cloth Y can be continuously edged.

It is intended to spread outward.
[0037]
Next, the operation of the delivery device will be described with reference to FIGS.
(1) The cloth corner gripping means 22 and 23 of the movable body 2 located at the end of the apparatus (left end in FIG. 2) are moved by gripping one corner of the square cloth Y. When the body 2 is moved along the guide rail 11 and the rectangular cloth Y is laterally drawn on the conveyor 5 and the rectangular cloth Y comes to the center of the apparatus, the gripping means 22 and 23 are released, The rectangular cloth Y falls on the conveyor 5. (This process is the same as the invention described in Japanese Patent Publication No. 6-49119)
(2) The rectangular cloth Y that has been released from the gripping means 22 and 23 and dropped onto the conveyor 5 is transferred to the front (the front side of the apparatus), is transferred to the divided conveyor 81, and is transferred to the divided conveyor 81. The cloth Y is adsorbed by the division conveyor 81, transferred further forward by the rotation of the division conveyor 81, and when the cloth Y comes out of the one-line detection sensor, the division conveyor 81 stops. Since the time-division conveyor 81 is divided into two at the central portion, each of the division conveyors 81 is stopped by the respective one-line detection sensors even when the rectangular cloth Y is inclined. At this time, most (about 70%) of the square-shaped cloth Y is detached from the division conveyor 81 and hangs down (FIG. 9).
(3) The pressing roller 86, which has been retracted to a position where there is no hindrance to the falling of the rectangular cloth Y, rotates, and the rectangular cloth Y hanging from the dividing conveyor 81 is pressed against the dividing conveyor 81, and the dividing conveyor 81 The rectangular fabric Y is held at 81. In this state, the rectangular cloth Y is sent by the dividing conveyor 81 to a position where the end of the rectangular cloth Y does not come off (FIG. 10).

Since the delivery device 88 is vacuuming the tip horizontal portion with a fan on the back, the rectangular fabric Y is held in the blown position (FIG. 12).
(6) When the delivery device 88 is retracted at a high speed, the rectangular cloth Y held by the delivery device 88 is peeled off from the delivery device 88 due to the speed difference from the vacuum conveyor 82, and is transferred to the vacuum conveyor 82. The rectangular cloth Y transferred to 82 is transferred toward the discharge conveyor 91. At this time, the hanging part of the rectangular cloth Y is transferred while being expanded and shaped by the spreading conveyor 90 (FIG. 13).
(7) The rectangular cloth Y placed on the vacuum conveyor 82 is transported to the discharge conveyor 91 by the rotation of the vacuum conveyor 82, supplied to a press machine such as a roll ironer 92, and pressed there. (FIG. 14).
[0038]
Since the transfer apparatus according to the present invention performs the above-described series of operations, the rectangular upper cloth Y that is stretched by the stretching apparatus and supplied onto the conveyor 5 is quickly transferred to the vacuum conveyor 82. Therefore, the next rectangular upper cloth Y can be stretched by the stretching device.
[0039]
As described above, the transfer device of the present invention has been described based on the example in which the sheet isotropic fabric is supplied from the side of the device, and the sheet isotropic fabric is applied to the edging device. The transfer device is a device that supplies fabric from the front of the device, as in the invention of Japanese Patent Application No. 10-303283 (Japanese Patent Application Laid-Open No. 2000-116996) filed earlier by the present applicant. The present invention can also be applied to delivery of fabrics to the conveyor 82.
