Description

[Detailed description of the invention] Support ring for material handling bags The present invention automatically performs material transfer operations. Support rings for bags used for handling laundry, especially bags for handling laundry. Concerning support rings for logs.

In commercial laundries, dirty and clean laundry is typically stored in collapsible bags. The students are packed into bags and patrolled the premises. These bags are rigid at the top open end supported by a ring, usually circular or square. These resources The washing machines are hung in sequence from the overhead conveyor rails and circulated around the laundry area. This makes it easy to move the bag around.

When empty, the bag is stored on a pair of separate storage rails. In general, support The bag is tilted by mechanical means to collapse the bag into near vertical alignment. get.

The problem with traditional rings is that the rings cannot always achieve the desired vertical position. However, they are tilted at various angles and cannot be twisted together. There is a particular thing. This means taking up valuable storage rail space.

According to the invention, a support for a collapsible bag for use in a material handling system is provided. two rings attached to the ring at opposite points of equilibrium on the ring It has hanging shackles that allow the ring to be carried overhead. It can be hung from a type conveyor, and each shackle Contains holes in which fittings can be installed to attach the ring to the conveyor. each shackle is axially spaced from the ring and holds the ring in a horizontal position. A first hanging point that can be hung, and a circumferential direction from this first hanging point. Separate and adjacent to the rings, suspending the rings in a nearly vertical position a second suspension point that can be passes outside the ring and outside the plane containing the two suspension points. You can get a support ring with

The support ring may be circular, oval, hexagonal, or square.

The first hanging point is located above and in alignment with the ring, and when in use, the laundry bag is suspended downward from the ring. As used here, "upper", "upper", "lower" Terms such as "part", "lower side", and "lower side" all refer to the normal working condition of the support ring. This is about the horizontal posture of.

The invention will now be explained by way of example and with reference to the accompanying drawings, in which: FIG.

First, referring to Figure 1.2, there is a laundry handling system used in a commercial laundry. A conventional circular mild steel support ring 11 for the stem is shown. Hereinafter, the present invention In order to provide a thorough understanding of the prior art, the prior art will be explained in detail. The support ring 11 is It has two diametrically opposed suspension shackles 12.13, and these shackle The buckle is best seen in Figure 2. During normal transfer operations, the support ring 11 is It is suspended from one overhead rail 14, and this rail is connected to two overhead rails. It extends back and forth along the center line CL between the lines.

Each yakkle 12.13 is linked from a hook 16 attached to a bracket 17. or is suspended by a joint 15, and the bracket 17 is attached to the conveyor rail. It is suspended from the wheel 14 by self-closing rollers 18.

The support ring 11 opens the bottom of a laundry bag (not shown) suspended therefrom. A locking cleat is used to control the cord used to close the Even if cleat) 23 and cord peg 24 are installed good. The cord can be locked to the cleat to keep the bag closed during normal transport operations. can be kept.

The two shackles are each in the form of a steel loop, with a ring attached to each end. (when the support ring is horizontal in normal working mode) It is arched upward between the two ends. Each shackle 12.13 supports located in a single plane extending at right angles to the plane of the ring 11, the links or joints It constitutes a movable hole 19. During normal transfer operations, each link 15 a support ring axially spaced from the support ring and adjacent one end of the shackle; 11, and at the apex of each shackle 12 and 13. It is located at a first suspension point 21 formed in the same manner. The support ring will be explained later. When stored in a vertical position, each link 15 extends circumferentially from the first suspension point 21. a second suspension on each shackle spaced apart in direction and adjacent to the support ring 11; At the drop point 22! will be rewritten. The first hanging point and the second hanging point of each shackle. The portion between the lowering points is twisted to form a detent 26, which The stop prevents the link 15 from accidentally slipping out of position during normal transfer operations. It is designed to prevent

At the bag stacking station (best seen in Figures 3 and 4), The type transfer rail 14 is divided into two parallel rails 14A and 14B, and a support link is provided. The bag 11 and its empty bag are carried by roller units 17.18 on two rails 14A. , 14B along the rail 14 to a position where it can move laterally.

When the support ring 11 is between the two rails 14A, 14B, these support rings The ring can be tilted into a substantially vertical position by actuator 25. this slope In operation, the support ring 11 rotates relative to the link 15 in the direction of arrow A in FIG. do.

The shackle moves relative to the link 15 so that the detents 26 each can move freely through the link 15 of the bag, supporting the link under the weight of the bag. The hanger 11 is finally suspended from the second hanging point 22. This is the second AIN best understood.

As previously explained, the support ring 11 always assumes the vertical position shown in FIG. 2A. is not limited. If no vertical position is taken, all support rings form a constant angle. For example, one support ring is tilted at 70 degrees and the other support ring is tilted at 40 degrees. It is possible that it will tilt. This saves space at the bag stacking station. It will be wasted.

The present invention provides a shack in which bags are stacked almost vertically and at a nearly constant angle of inclination. Almost the same support structure as described for the prior art, except that the shape of the support structure is different. provide services.

5.61, the support ring 11 has a pair of shackles 33. However, only one of them is shown for convenience. The shackle 33 is the lug of the mild steel tank. which extends in the circumferential direction of the support ring 11 and is welded to the support ring at each end. It is. One end 34 of the shackle 33 is welded to the top of the support ring 11; Its opposite end 35 is welded to the bottom of the support ring.

As in the past, on the center line of the support ring adjacent to the one end 34 of the shackle 33 At the top of the shackle 33 located above the support ring in the axial direction, There is a lowering point 21.

In this case, the shackle 33 is not located in a single vertical plane as in the prior art. First, draw a three-dimensional path. The first portion 36 is suspended upwardly from the support ring 11. Extends to the lowering point 21 and extends at a bias angle B with respect to the center line CL of the support ring 11 ing.

A second portion 37 extends downwardly from the first suspension point 21 to the center of the support ring. the same offset angle with respect to the line, and the first and second portions of the shackle 33 form a single flat It will be located within the plane.

The bias angle B is approximately 12 to 14 degrees.

The second portion 37 extends to an outwardly spaced outer point 38 of the support ring 11 and then A third portion 39 of the shackle extends downwardly from this outer point 38 at the same angle of inclination; The underside of the support ring 11 offset towards the second portion 37 and to which it is welded pass above. As can be seen from FIG. 5, the outside of the third portion 39 and the second portion 37 The main length part adjacent to the side point 38 is the same, inclined with respect to the plane of the support ring 11. Located within a plane. The second suspension point 42 is located adjacent to the lower surface of the support ring 11. Place it on the shackle outside of ring 11! do.

As in the past, the portion of the shackle 33 between the first hanging point 21 and the outer point 38 is conventionally twisted to provide a detent 26 and prevent accidental tilting of the support ring. It is designed to prevent

This kind of support ring 11 is always tilted in a substantially vertical position between 85 and 90 degrees. , resulting in efficient organization on bag stacking stations with minimal space. I found out that it can be added more easily.

During the tilting operation, the suspension point of the shackle from the link 15 is connected to the support ring 11. from axial alignment with the support ring to a position outside the support ring.

A second embodiment of the invention is shown in Figure 7.8, in which a shackle similar to 33 is shown. A support ring 11 is shown having a pair of similar shackles 53, which One end 54 of the shackle adjacent to the first suspension point 21 is at the top of the support ring 11. The opposite end 55 of the shackle is also welded to the top of the support ring 11. The difference is that In all other respects, Shackle 53 is identical to Shackle 33. , and describes a three-dimensional path extending to an external point located outside the support ring.

Support rings and bags with this type of shackle are always at an angle of 80-85 degrees. The angle between I found out that you can add them all together.

Summary book Support ring for collapsible bags used in laundry handling systems ( 11) is a two-piece structure for hanging it from the overhead conveyor (16, 17, 18). It has two diametrically opposed suspension shackles (33). Each shackle ( 33) constitutes the hole for the coupling (15) and is the first hole for suspending the support ring horizontally. 1 suspension point (21) and a second suspension point (42) from which the support ring is suspended vertically. ).
