Abstract

PURPOSE:To automatically spread a substance to be washed by a method wherein either an endless belt or a partition rail is vertically moved. CONSTITUTION:When substances to be washed are charged in a chute 2, the substance to be washed is disentangled from each other by means of an up-air- injection flow generated by an air injection means 3 and dropped on a conveyor 8 for spread. Through conveyance by means of an adsorption conveying means, an upper surface is adsorbed and the substance to be washed is conveyable on endless belts 8a. A coupling means being an engaging means for the substances to be washed is coupled to a coupling means mounted on the endless belts 8a running in a direction crossing the conveying direction of the substance to be washed and in a lateral and outward and reverse directions to each other. Thereby, the substance to be washed is laterally spread by means of conveyors for spread. Since, when the substance to be washed is spread in a direction crossing a longitudinal direction, either the endless belt 8a or a partition rail 8b is vertically moved, coupling means for the substance to be washed and for a conveyor 8 is uncoupled by means of the partition rail 8b arranged in parallel to and between the conveyors 8 for spread. This constitution automatically spreads a sheetform substance to be washed.

The j! ! (A method was adopted in which either the end belt or the partition bar was moved up and down.

[For production]

When the laundry items are put into the chute, they are loosened by the upward air jet flow generated by the air jetting means, are dropped onto the spreading conveyor, and the upper surface is removed by the suction transfer means, etc. It is adsorbed and can be freely transported on an endless belt for spreading.

Since the coupling means serving as the "interlocking means" for the objects to be washed is coupled to the coupling means provided on the endless belt that rotates oppositely in left and right and outward directions intersecting the direction of transport of the objects to be washed, The laundry items are spread from side to side by a spreading conveyor.

When the laundry to be washed is spread in a direction that intersects the longitudinal direction, either the endless belt or the partition bars move up and down, so the partition bars arranged parallel to each other between the spreading conveyors The connection between the article to be washed and the spreading conveyor is released.

〔Example〕

Hereinafter, details of one embodiment of the present invention will be described with reference to the drawings.

In Fig. 1, l is a supply conveyor for backrest covers A as items to be washed, 2 is a chute for feeding the backrest force bar A, and 3 is a conveyor for loosening the laundry items provided around the chute 2. It is an air outlet.

4.4' is a receiving plate for the backrest cover A provided at the bottom of the chute 2; 5.5'; 6 and 6' are a conveyor for polymerization and dissociation of the backrest cover A and a conveyor for sorting. .

A storage wagon 1a is connected to the supply conveyor 1, and a fixed amount of backrest covers 8 having the coupling means B are fed into the chute 2.

The backrest cover A, which is the object to be washed, may be provided with one coupling means B1 as the "engaging means" as shown in Fig. 5 (a), or as shown in Fig. 5 (opening). It is also possible to provide two. An upward air jet is formed in the chute 2 from an air jet hole 3, and the backrest cover A, which is an article to be washed, falling inside the chute 2 is loosened by this air jet.

Then, the dropped backrest cover A is placed between shoes 1-2.
Receiving plates 4, 4' protrude alternately from the opposing lower wall surfaces of the
It gets caught and slides downward.

The conveyors 5 and 6 are brush-shaped, and the conveyors 5 and 6 are brush-like.
'． 6' is a brush-like roll that rotates in the opposite direction to the traveling direction of the conveyor 5.
The backrest cover 8 is rotated faster than the washing machine to unravel the overlapping of the backrest covers 8, which are the items to be washed.

At the lower part of the downstream side of the conveyor 6, a pair of sorting conveyors 7.7 are vertically arranged with their upper parts close to each other.
As shown in the figure, a hook serving as the other coupling means B2 of the "interlocking tape" is provided in an upright manner.

Therefore, depending on the direction of the connecting means B1, the backrest force bar A as the laundry item that has fallen onto the conveyor 7.7 is caught by the connecting means B2 of the left or right endless bell 7a facing the backrest force bar A, and endless bell}? carried by the endless bell}? The bond is separated by a scraping piece 9 attached to the lower part of a and falls onto a conveyor 8.8 for longitudinal spreading arranged downstream.

The backrest covers A that have not been captured by the sorting conveyors 7, 7 are stored in the tray IO and returned to the supply conveyor 1 again.

Further, as shown in FIG. 3, the spreading conveyor 8 is
The shape is made up of an endless belt 8a that is freely rotatable in the left and right directions intersecting the transfer direction A of the backrest cover 8, and in the outward direction B, and partition bars 8b arranged alternately and parallel to the endless belt 8a. be done.

Similar to the endless belt 7a, the endless belt 8a is provided with a connecting means B2 made of a hook. Either the endless bell 8a or the partition bar 8b can move up and down relative to the other.

At this time, the connection relationship between the backrest cover 8 as a workpiece and the connecting means B, , B2 of the backrest cover Δ and the endless bell }8a is extended horizontally and balanced across the backrest cover 8 in the elongated direction. As shown in FIG. , 8a may be moved up and down at different times.

In this way, the coupling means BI on the backrest force bar A as the laundry object are captured separately by the coupling means B2 and B2 of the endless bells 3a and 8a, so that
As the endless bells 3a and 3a rotate, the backrest cover A is pulled and extended by the left and right outward openings intersecting the transport direction A (longitudinal direction).

Then, when the backrest cover A is extended in the left-right direction that intersects the longitudinal direction (direction that corresponds to the transport direction A), the endless bells 3a and 8a are lowered [see Fig. 4 (c)], or Endless bell} 8a, partition bar 8b for 8a
By rising, the coupling means B of the caper 8 for the backrest is
1 is separated from the coupling means B2, B2 of the endless bell}8a, 8a.

At this time, in this embodiment, the endless bells 8a and the partition bars 8b are alternately arranged in parallel, but the invention is not necessarily limited to this, and they may be arranged at appropriate intervals with respect to the endless belt 8a. Means B. , B2 can be dissociated.

Reference numeral 11 indicates a number of backrest covers A to be washed are provided above the conveyor 8 for spreading in left and right directions perpendicular to the longitudinal direction and outward direction B so as to be movable in the flow direction A. The suction/transfer means 11 is a suction/transfer means, and the suction/transfer means 11 uses, for example, a vacuum suction roller to suction the backrest cover A, which is the object to be washed, and place it at a predetermined location.
For example, the conveyor 1 for the next stage of longitudinal spreading shown in FIG.

This conveyor 12, 12' for longitudinal direction spreading has the same structure as the conveyor 5, 5' for polymerization and dissociation so that it can be freely connected to the coupling means B1 of the force bar A for the backrest. Brush-like, conveyor 12'
are brush-faced rollers that extend the backrest cover A in the longitudinal direction by rotating in opposite directions.

Reference numeral 13 denotes a scraping piece provided at a desired location on the conveyor l2, and is used to connect the backrest connecting means B. The purpose is to dissociate the bonds of

Reference numeral 14 denotes a receiver for accumulating uncoupled backrest covers 8 as items to be washed from the conveyor 12, 12' for extending in the longitudinal direction.

In this way, the backrest force bar A is extended in the longitudinal direction and in the left-right direction crossing the longitudinal force direction, so the backrest covers A as items to be washed are stacked and stored in the receiver 14. When carrying the bag, the front (upper side in the drawing) is aligned and the connecting means B are aligned vertically, making handling and attachment to the backrest convenient.

In the above embodiment, an interlocking tape was used as the bonding means, but in other embodiments, the backrest cover A as the item to be washed may be bonded with a magnetic sheet such as a sheet having metal fibers or a thin metal film. A means Bl' is provided (see FIG. 6), and a certain coupling means B2' is provided from a corresponding magnetic piece on the endless conveyors 7a and 8a of the sorting conveyor 7 and the spreading conveyor 8. (See Figures 1, 6, and 7).

In addition, the backrest cover A is provided with one or more coupling means B1 on the upper part of the back surface, thereby carrying out a spreading conveyor 8 for spreading in the left and right directions intersecting the longitudinal direction, and a spreading conveyor 8 for spreading in the longitudinal direction. However, instead of using this connecting means B+, the backrest cover A itself is woven from fibers having loops like "interlocking tape" on the surface. If so, this allows the coupling means B of the conveyors 8,
2 may be combined.

〔Effect of the invention〕

Since the present invention is as described above, it is possible to automatically spread out a sheet-like item to be washed.
