Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag supporting device and a bag reversing device in a laundry conveying bag conveyor of an automatic cleaning system for continuously washing many sheets, yukatas, macula covers and the like.

[0002]

2. Description of the Related Art There are known automatic cleaning systems for continuously washing many towels, sheets, yukatas, pillow covers and the like. In this automatic cleaning system, a large number of storage bags, each of which holds a large amount of laundry and whose bottom can be opened and closed, are hung on a traveling roller placed on a conveyor rail of a bag conveyor, traveled along the rail, and then fixed. Stop at the open position and perform work such as supplying laundry to the storage bag or dropping it from the storage bag.

In a bag conveyor of a previously known automatic cleaning system, in its working area, a large number of bags have their upper openings opened, that is, a bag frame consisting of rings forming the upper openings of the bag is horizontal. Although the bag is moved to the position, a large number of empty bags are collected and stored when the bag is not used. At the time of collecting the empty bags, if many empty bags are collected with the upper opening of the bag open, the bag frames are arranged in a horizontal position, which requires a large storage space, which is not preferable.

Therefore, when a large number of bags are not used, when the bag frames of the respective bags are inverted from the horizontal state to the vertical state, the openings of the bags are also closed by the bags.
Since the bag itself is also crushed and reduced in size, it is effective that a large storage space is not required if a large number of bags are assembled in such a closed state.

Even in the past, when the bag was not used, the bag frame was inverted from the horizontal position to the vertical position for collective storage. That is, as shown in FIG. 3, one to two rails 1 of the bag conveyor at the starting point A position of the bag storage location.
When the bag is hung in one rail and hung on one rail, the bag is hung on the rail at the front-back position in the traveling direction. The bag is turned 90 degrees so that the bag is suspended at the left and right positions in the traveling direction, and the bag frame is inverted from the horizontal position to the vertical position at the starting point B position of the two rail positions. And at the end point C position of the two rail positions,
The bag frame that was in the vertical position was turned back to the horizontal position, and the two rails were returned to one rail at the end point D position of the storage location. At this position, the bag was turned 90 degrees in the horizontal position and the one rail I try to hang it in the front-back position.

[0006]

As described above, since the bag frame is reversed from the horizontal position to the vertical position and vice versa, the bag frame support structure is devised.
Conventionally, a pair of rectangular support blocks that suspend the rails and support the bag are formed with a groove crossing in a cross shape on the opposing surfaces, and a shaft hole is formed at the center position of the crossing of the groove. The shaft is rotatably pierced, and the shaft is pierced into the bag frame to project the inside of the bag frame inward. It is configured by press-fitting into one of the cross grooves of the block, and when reversing the bag frame, the bag frame moves from one of the grooves to another groove orthogonal to this against the elastic force of the Sarah spring. I was press-fitting. In this conventional bag support structure, the shaft is projected to the inside of the bag frame, and the saliva spring is attached to the inward protrusion. There is a problem in that it does not fall and it cannot be dropped and supplied from the bag.

In view of the above problems, it is an object of the present invention to provide a novel bag supporting device in which the laundry supplied from above into the bag is surely dropped and stored in the bag. Another object is to provide a novel bag reversing device.

And a bag supporting substrate which is loosely fitted in the through hole and accommodates a cylindrical stopper which is displaceable and suspended on a rail, and a through hole at a substantially central position, and a center coaxial with the through hole. A recess and a cross-shaped groove are formed on one side surface, stepped portions are formed on both ends on the opposite back surface, and both ends of a leaf spring having a through hole located coaxially with the through hole are locked to the stepped portion. And a support block having a recessed portion formed to receive it, the reversing support shaft of the bag frame is passed through the through hole of the support block and the through hole of the leaf spring, and its tip is connected to the cylindrical stopper of the support substrate. Lock the cylindrical stopper to the leaf spring and Securing the support block to support the substrate, characterized in that are 90 degrees reversible press-fitted into the concave hole of the support block bag frame.

Further, in the bag reversing device of the present invention, the pair of bag supporting substrates suspended on the rails are provided with the support blocks having the cross groove formed therein, and the bag frame is press-fit into the cross groove of the support block. While having a bag supporting device that allows the bag frame to be inverted between a horizontal position and a vertical position, a cylinder that is pivotally supported at an intermediate position of a vertical portion of a bridge member fixed on a rail and is mounted on a horizontal portion of the bridge member Is operated to move the tip of the bag supporting device closer to and away from the bag supporting board of the bag supporting device, and the tip of the pivoting arm presses and fixes the bag supporting board at the time of approaching the rotary supporting arm. Is provided, and an operating rod for inverting the bag frame is provided on the rotation shaft thereof.

[0010]

In the bag supporting device of the present invention constructed as described above, the bag frame is horizontal when the reversing supporting shaft portions at two opposite positions of the bag frame are pressed into the horizontal concave grooves of the supporting block. Maintains position and opens bag opening. Then, when a reversing actuation force is applied to the bag frame by the bag reversing device, the bag frame pushes the edge of the concave groove of the support block, and the cylindrical stopper connected to the reversing support shaft of the bag frame causes the leaf spring to be recessed in the support block. Of the bag frame, so that the bag frame is released from the horizontal groove of the support block and is reversely pressed into the vertical groove.

Similarly, in the bag reversing device of the present invention, the rotating arm is rotated by the cylinder, and the tip end of the rotating arm presses the supporting substrate for supporting the bag frame so that the supporting substrate does not move. Then, the rotary actuator provided at the tip of the rotating arm operates, and the operating bar provided on the rotating shaft pushes the bag frame to reverse the bag frame from the horizontal position to the vertical position or vice versa.
