Further, a belt conveyor C for conveying a cloth lump from a dryer (not shown) to the cloth sowing apparatus is provided above the right end of the frame 1 in FIG.

  The frame 1 here has substantially the same height as the tatami apparatus F, and an unwinding conveyor 2 comprising a belt conveyor is disposed at the upper end of the frame 1, and the unwinding conveyor 2 has one end. 1 is located at the right end in FIG. 1 of the frame 1 and the other end is located at the left side in FIG. 1 of the frame 1 and extends at an angle so as to increase from the one end toward the other end. The cloth lump L fed from the belt conveyor C onto one end thereof is conveyed toward the other end.

  A gap spacing conveyor 3, which is also a belt conveyor, is also arranged at the upper end of the frame 1, and this gap spacing conveyor 3 is the left end of the unwinding conveyor 2 in FIG. Immediately below, one end, which is the right end in FIG. 1, is connected to the unwinding conveyor 2 and the other end is positioned at the left end in FIG. 1 of the frame 1, for example, faster than the unwinding conveyor 2. 1, a plurality of pieces of cloth P unraveled from the cloth lump L on the unwinding conveyor 2 are spaced apart from each other and conveyed toward the other end, which is the left end in FIG. 1. .

  Further, a plurality of guide plates 4 are erected on the upper end of the frame 1 along both sides of the unwinding conveyor 2 and the spacing conveyor 3, and these guide plates 4 are connected to the unwinding conveyor 2. And the fall of the cloth from the side part of the conveyor 3 for spacing is prevented. In the cloth spreading device of this embodiment, the loosening member 5 is disposed above the intermediate portion and the other end portion of the loosening conveyor 2 and the other end portion of the spacing conveyor 3, respectively. The support shaft 5a and the tip 5b extending in a direction orthogonal to the support shaft 5a and divided into a plurality of portions are formed in a comb shape as a whole.

  Both ends of the support shafts 5a of the three loosening members 5 are coupled to a loosening member swinging mechanism 6 provided at the upper end of the guide plate 4 as a loosening member moving mechanism. The moving mechanism 6 rotatably supports both end portions of the support shaft 5a, and pushes and pulls a crank arm provided at one end portion of the support shaft 5a with an air cylinder (not shown), for example. As shown by a solid line and a broken line in FIG.

  Furthermore, in the cloth sowing apparatus of this embodiment, as shown in FIGS. 1 and 3, the two carry-out conveyors 7 are attached to the frame 1 with their one ends facing each other so as to be positioned below the spacing conveyor 3. In addition, a further guide plate 8 is disposed on the frame 1 so as to extend from the vicinity of the other end of the spacing conveyor 3 toward the opposite end of the carry-out conveyor 7. The table carry-out conveyors 7 are inclined and extended so as to be higher from one end portion to the other end portion thereof, and the other end portions thereof are respectively located on the left side of the tatami apparatus F in FIG. Adjacent to the fabric input conveyor.

  In the cloth milling apparatus of this embodiment, a control panel 9 having a controller (not shown) having a normal computer is provided. The controller operates based on a program given in advance, and each conveyor 2 , 3 and 7 and the air cylinders (not shown) of the loosening member swinging mechanisms 6 are controlled.

  That is, in the cloth sowing device of this embodiment, when the cloth lump L conveyed by the belt conveyor C from a dryer (not shown) is dropped into the one end of the unwinding conveyor 2, the controller First, the unwinding conveyor 2 is operated, and the cloth lump L is slowly moved forward to the left in the drawing as shown in FIGS. 1 and 2, and the cloth lump L is self-weighted during the forward movement. Rotate in the return direction and break apart to some extent. When the cloth lump L that moves forward while loosening reaches below the loosening member 5 in the intermediate part of the loosening conveyor 2, the controller uses the loosening member swinging mechanism 6 to move the loosening member 5 to its tip 5a. The tip 5a of the loosening member 5 is engaged with the upper part of the cloth lump L that is slowly moving forward to the left in the drawing, and then the loosening member swinging mechanism 6 is moved. Then, the loosening member 5 is swung so that the tip end portion 5a is raised while being retracted, and the engaging portion of the cloth lump L is pushed back backward while being lifted by the tip end portion 5a of the loosening member 5.

  Next, the controller temporarily stops the unwinding conveyor 2 and then operates it in the reverse direction to slowly move the cloth lump L to the right in the drawing, and the unwinding member swinging mechanism 6 during the backward movement. Then, the loosening member 5 in the middle part is swung so that the front end part 5a moves forward while being lowered, whereby the upper part of the cloth lump L on the loosening conveyor 2 is pulled forward by the loosening member 5 and unraveled. Then, when the cloth lump L is moved backward to some extent to the right in the drawing, the unwinding conveyor 2 is temporarily stopped and then moved forward again. In this way, the controller causes the loosening conveyor 2 to repeatedly advance and retreat as indicated by the arrows in FIG. 1, and causes the loosening member swinging mechanism 6 to move the intermediate loosening member 5 up and down and back and forth. The cloth lump L on the loosening conveyor 2 is moved forward to the other end of the loosening conveyor 2.

  Next, the controller moves the unwinding member 5 at the other end of the unraveling conveyor 2 with the unwinding member swinging mechanism 6 in the same manner as the unraveling member 5 at the intermediate portion, and moves up and down and back and forth. The cloth lump L that has been swung to reach the other end of the loosening conveyor 2 is leveled further, and a part of the cloth P of the cloth lump L is transferred to the other end of the loosening conveyor 2. Is intermittently dropped onto the one end of the conveyor 3 for spacing. In addition, the controller operates the spacing conveyor 3 at a transport speed faster than that of the unwinding conveyor 2, for example, so that the plurality of cloths P, which have been loosened from the cloth lump L and dropped onto the spacing conveyor 3, are mutually connected. It conveys toward the other end part of the conveyor 3 for spacing at intervals.

  Next, as shown in FIGS. 3 and 4, the controller moves the unwinding member 5 at the other end of the spacing conveyor 3 up and down and rocks back and forth by the unwinding member swinging mechanism 6, thereby separating the spacing conveyor 3. While the cloth lump L reaching the other end of the cloth is further flattened, a part of the cloth P of the cloth lump L is intermittently guided from the other end of the spacing conveyor 3 by the guide plate. 8, the operator W is dropped onto the one end of the two carry-out conveyors 7, and each worker W operates the carry-out conveyor 7 on his / her side by operating a switch connected to the controller, for example. The cloth P on the carry-out conveyor 7 is moved to the hand, picked up one by one, and put into the cloth input conveyor of the tatami apparatus F.

  Therefore, according to the cloth sowing apparatus of this embodiment, the cloth lump L composed of a plurality of small cloths entangled with each other is automatically unwound and carried out, for example, on the carry-out conveyor 7 by about 20 sheets. Therefore, it is possible to reduce labor and manpower for unraveling the cloth lump by hand to some extent beforehand.

  Further, according to the cloth spreading device of this embodiment, the loosening member 5 has a comb shape in which the front end portion 5b is divided into a plurality of portions, and the front end portion 5b engages with a part of the cloth lump L. The cloth lump L can be efficiently unwound by applying a pressing force to a plurality of locations of the cloth lump L almost simultaneously.

  Furthermore, according to the cloth sowing device of this embodiment, the unwinding member swinging mechanism 6 that swings the distal end portion 5b of the unwinding member 5 in the front-rear direction and the unwinding conveyor 2 are combined to move forward and backward to advance. And a controller that operates the loosening member swinging mechanism 6 in conjunction with the advance and retreat operation of the unwinding conveyor 2 to swing the unwinding member 5 backward and forward. When the conveyor 2 is moved forward, the loosening member 5 is moved backward to push back a part of the cloth lump L, and when the loosening conveyor 2 is moved backward, the loosening member 5 is moved forward to move the cloth. Since a part of the lump L is pulled forward, the cloth lump L can be unraveled more efficiently.

  Furthermore, according to the cloth sowing device of this embodiment, one end is connected to the other end of the unwinding conveyor 2, and a plurality of pieces of cloth unraveled from the cloth lump L on the unwinding conveyor 2. Since there is a spacing conveyor 3 that transports P toward the other end with a space between each other, the spacing conveyor 3 is transported at a higher speed than the unwinding conveyor 2, for example Since a plurality of pieces of cloth P unraveled from the cloth lump L are conveyed on the conveyor 2 with a space between each other, the cloth sowing device leveles the cloth P unraveled from the cloth lump. Can be carried out.

  Furthermore, according to the cloth spreading device of this embodiment, the loosening member 5 is also disposed above the spacing conveyor 3, so that the cloth lump L that has been unraveled on the loosening conveyor 2 is further loosened. be able to.

  And according to the cloth spreading device of this embodiment, the unwinding conveyor 2 is inclined and arranged so as to become higher from the one end to the other end, and one end of the spacing conveyor 3 is unraveled. Since the cloth lump L on the unwinding conveyor 2 rises from one end of the conveyor toward the other end, it rotates in the return direction by its own weight. However, since it collapses to some extent, it can be more efficiently unraveled.

  FIGS. 5 (a) and 5 (b) are explanatory diagrams showing a conventional method for supplying cloths that have been washed, dewatered and dried one by one to a tatami apparatus, and do not use a cloth sowing apparatus. In the prior art, as shown in FIG. 5 (a), first, used cloths collected from accommodation facilities such as hotels and contractors such as hospitals are first washed in a continuous washing machine and then dehydrated in a dehydrator. Then, it is dried by a drier and conveyed to the vicinity of the tatami apparatus Fno by a conveying system such as a belt conveyor C. The cloth lump of one time may be about 50 kgw or baked 100 kgw. Here, the cloth lump of about 50 kgw is about 550 sheets with a face towel and about 144 sheets with a bath towel.

By the way, there is a case where a plurality of tatami apparatus F is used because of the necessity of processing a large amount of cloth. In that case, the conveyance of the cloth to the tatami apparatus F is as shown in FIG. In the case where the towel is 100 kgw, it is about 1.3 m ³ in a stacked state. Therefore, when the towel is stored in a general cart T, the working range of the worker W is 200 mm to The height is 1700 mm. Therefore, since the worker W cannot pull out the cloth as it is, a part of the cloth P is taken out from the carriage T on the table, and the cloth is supplied to the tatami apparatus F one by one from there.

  However, there is a problem that the lump of cloth L in the carriage T is often entangled and takes time to take out. Moreover, the cloth falls to the floor due to the entanglement during the take-out, and the operator W has to squat down and take up the cloth on the floor. There is a problem that it is difficult to concentrate on the input operation.

  On the other hand, if the cloth sowing apparatus of the present embodiment is used, small cloths such as towels can be divided into about 20 sheets and supplied to the operator, and the tangling and picking height of the cloth is reduced. Thus, the worker can be dedicated to the loading operation, and the work posture of the worker W can be stabilized by constantly supplying the cloth to the same work height by the carry-out conveyor 7 and reducing the operations other than the loading operation. At the same time, the number of sheets inserted into the tatami apparatus F can also be stabilized, and as a result, the number of sheets loaded into the tatami apparatus F can be reduced per hour by using the cloth-sewing device of this embodiment. It was possible to increase about 130 sheets.

  Although the present invention has been described based on the illustrated examples, the present invention is not limited to the above-described examples and can be appropriately changed within the scope of the claims. Although it is arranged to be inclined, the unwinding conveyor 2 may be horizontally disposed. In the above embodiment, the unwinding conveyor 2, the spacing conveyor 3 and the carry-out conveyor 7 are each constituted by a belt conveyor. However, any one or more of them may be replaced with other types of conveyors.

  Further, in the above embodiment, the controller moves the unwinding conveyor 2 forward and backward. However, the unwinding conveyor 2 may be moved forward only. In the above embodiment, the unwinding member 5 has a comb shape. The loosening member may be in the form of a plate, a roller, or a rod. Further, in the above embodiment, the loosening member 5 and the loosening member swinging mechanism 6 are provided three by three. However, the loosening member 5 and the loosening member swing are provided. The mechanism 6 may be appropriately increased or decreased and disposed at an appropriate position. In the above embodiment, the loosening member swinging mechanism 6 is provided as the loosening member moving mechanism. However, the loosening member moving mechanism may move the loosening member along a rail or the like linearly or in a curved line. Further, the loosening member may be supported so as to be able to swing without having a driving mechanism such as an air cylinder, and may always be urged by an elastic member toward its lower swing limit position.

  Thus, according to the cloth sowing device of the present invention, the cloth lump comprising a plurality of cloths entangled with each other can be automatically unwound, so that the cloth lump is unraveled to some extent manually by hand beforehand. Can save labor and manpower.
