FIG. 11 is an explanatory diagram of carrying out the work clothes in which the hood portion is folded.

  The hood part folding part 40 is installed on the extension line of the conveyance path of the hood part folding conveyance part 32 as shown in FIGS. As shown in FIG. 9, the optical sensor 41 is arranged so that the top of the hood portion 110 is positioned to block the optical sensor 41 when the neck 150 comes near the carry-in port 38. As shown in FIG. 9B, in order to make the neck 150 become the head of the bent portion immediately after being pushed in, the insertion is actually started when the neck 150 comes near the lower side of the carry-in port 38. The position of the optical sensor 41 is adjusted. When the optical sensor 41 outputs a detection signal, the drive unit 42 receives the detection signal and controls the folding knife unit 43 to protrude.

  When the folding knife 43 is protruded, the hood 110 is pushed into the carry-in port 38 as shown in FIG. 9B. The body part 130 is in the arm part folding conveyance part 31 and is difficult to move by contact, and only the hood part 110 is folded into the carry-in entrance 38. Then, the folding knife portion 43 is immediately pulled back. In the state where the hood part 110 is folded in this way, the hood part folding conveyor 36 and the main conveyor 35 of the hood part folding transport part 32 are transported.

  Subsequently, as shown in FIG. 10A, when the work clothes 100 are conveyed and the neck portion 150 of the work clothes 100 comes into contact with the carry-out conveyor 37 arranged so as to block the conveyance path, It is moved in the conveying direction, and is carried out as shown in FIG. Finally, as shown in FIG. 11, the work clothes 100 in a state where the arm part 120 and the hood part 110 are folded are carried out. And it is conveyed to the apparatus in a back | latter stage, for example, the folding machine which folds into four, and is finally accommodated in a storage basket (not shown).

The Landori folding machine of the present invention has been described above. In the present embodiment, the explanation has been made assuming that the land folding machine performs both the folding of the arm and the folding of the hood. However, it may be a Landry folding machine in which the hood part folding part 40 in FIG. 1 is removed and only the arm part is folded. Such a configuration is applied to work clothes having no hood portion.
On the contrary, it may be a Landry folding machine that removes the arm folding part 20 and only folds the hood. These are applied when it is not necessary to fold the arm.

In such a Landori folding machine, in particular, the arm folding part has a simple configuration without a complicated mechanism, and therefore there are advantages such as reduction in manufacturing cost and ensuring of operation reliability.
In addition, since the transport unit is a transport unit made up of a large number of string-like or belt-like conveyor belts, the degree of freedom of movement of the conveyor belt can be increased and it can be easily transported even in changing transport paths such as in the arm folding part. it can.

Also, since the hood part is folded while the trunk part of the work clothes is fixed in the arm folding part, even if an impact is applied by the folding knife part, the body part side of the work clothes does not move. Only the hood part of the clothes moves, and when a large number of work clothes are folded, they are all folded at the same location (neck part) to ensure workability.
It has become possible to provide a Landori folding machine that reliably folds only the arm part of the work clothes, only the hood part, or the arm part and the hood part of the work clothes with a simple mechanism system as a whole.
