The upper transport section 200 has an upper first cheddar roll section 201 which is a cylindrical roller and an upper second cheddar roll section 202 which is a cylindrical roller. Further, in the upper tier transport section 200, an upper tier cheddar belt section 203 having a band shape that is rotatably hung around the upper tier first cheddar roll section 201 and the upper tier second cheddar roll section 202 is arranged. The upper transport section 200 has a second cheddar chassis 205 that supports the upper first cheddar roll section 201 and the upper second cheddar roll section 202 and serves as a main body.

Further, the upper transport portion 200 has a cylinder portion 220, a cylinder 221 having a cylindrical shape, and a cylinder shaft portion 222, which are arranged so as to be expandable and contractible. Further, the cylinder portion 220 is telescopically attached to the upper transport portion 200 and the pull-up portion 186.

The cylinder 221 is attached to the upper transport portion 200, and the cylinder shaft portion 222 is attached to the pull-up portion 186. Specifically, the cylinder 221 is connected to the cylinder mounting portion 206 which is integrated with the second cheddar chassis 205 in the upper transport portion 200 and projects upward, and the cylinder shaft portion 222 is mounted to the pulling portion 186. .. Therefore, when the cylinder shaft portion 222 in the cylinder portion 220 is pulled into the cylinder 221, the pulling portion 186 is pulled up to pull up the movable portion 180, and the opening K is between the movable portion 180 and the mounting portion 120. Appears. On the contrary, when the cylinder shaft portion 222 in the cylinder portion 220 is pulled out from the cylinder 221, the pulling portion 186 is lowered and the opening K is closed (see, for example, FIGS. 3A and 3B).

Cloth w is attached to the cloth input unit 100 having the above configuration. Specifically, initially, the opening K appears between the movable portion 180 and the mounting portion 120. That is, in a state where the sensor 131 does not detect the presence of the cloth w, the opening K appears between the movable portion 180 and the mounting portion 120. In this state, an operator (not shown) arranges one side wh of the cloth w so as to be placed on the mounting belt portion 125 in the mounting portion 120. That is, one side wh of the cloth w is placed on the mounting belt portion 125 in the mounting portion 120. The state in which one side wh of the cloth w is placed on the mounting portion 120 in this way is referred to as the first stage in which the cloth w is placed at the first position X (see FIGS. 2B, 6A, and B).

When one side wh of the cloth w is placed on the mounting belt portion 125 in the mounting portion 120 in this way, the sensor 131 detects the presence of the cloth w. As a result, the cylinder shaft portion 222 in the cylinder portion 220 protrudes from the cylinder 221, the pulling portion 186 is lowered, and the opening portion K is closed (see the movable portion 180'in FIG. 6B).

After that, one side wh of the cloth w is sandwiched between the mounting portion 120 in the lower stage portion 110 and the movable portion 180 in the upper stage portion 170, and the mounting belt portion 125 and the lower stage belt portion 125 are formed by the lower stage drive motor 146.

Further, with one side wh of the cloth w sandwiched between the mounting portion 120 and the movable portion 180, the cloth w is sandwiched between the lower transport portion 140 and the upper transport portion 200 and transported upward to the intermediate device 600 described later. Delivered.

As described above, it is sufficient for a worker (not shown) to place one side wh of the cloth w on the mounting portion 120 with the opening K appearing in advance, which saves the trouble of searching for both corners of the cloth w and further. Unlike the conventional device, the operation of pushing the cloth w into the gap between the upper conveyor and the lower conveyor becomes unnecessary. Therefore, since such an operation can be omitted, labor can be reduced, work efficiency can be improved, and the number of processed cloths can be increased.

Next, the intermediate device 600 of this embodiment will be described. The intermediate device 600 has a pair of expansion clamps 800, a right rear corner portion RR which is a right rear corner portion of the cloth w conveyed from the loading unit 100, and a left rear corner portion LR which is a left rear corner portion. It has a fixed catch roll portion 610, a movable catch roll portion 650 in contact with the fixed catch roll portion 610, and a delivery portion 670 movable in the front F and rear R directions for delivery to the 800. Further, as will be described later, the fixed catch roll portion 610 is arranged on both sides and coaxially with the lower second roll portion 142, which is a cylindrical roller of the lower transport portion 140 in the charging unit 100 (for example, FIG. 4A arrow view). , See FIG. 9A arrow view).

Further, the right rear corner portion RR and the left rear corner portion LR of the cloth w conveyed to the fixed catch roll portion 610 are sandwiched between the fixed catch roll portion 610 and the movable catch roll portion 650. By moving to the front F, the delivery portion 670 sandwiches the cloth w with the right rear corner portion RR and the left rear corner portion LR. Further, as will be described later, the delivery portion 670 holds the cloth w at the third position Z by moving to the rear R while sandwiching the cloth w with the right rear corner portion RR and the left rear corner portion LR. Can be done (see FIG. 2B).

Further, the intermediate device 600 may have a peeling roll portion 630 that is in contact with the fixed catch roll portion 610 and is arranged above the fixed catch roll portion 610. Further, the intermediate device 600 may have a right rear corner portion RR of the cloth w and a lifting portion 690 for lifting the left rear corner portion LR. As described above, the intermediate device 600 may have each of the above configurations.

Further, the fixed catch roll portion 610, the peeling roll portion 630, and the movable catch roll portion 650 are attached to the above-mentioned loading unit 100, and the delivery portion 670 and the lifting portion 690 are attached to the loading device 900. ing. In this case, as will be described later, the transfer portions 670 are arranged on the left and right sides of the main body portion 910 of the loading device 900, and can move to the front F and the rear R of the main body portion 910, that is, in the front-rear direction, and also to the rear R. You can wait at. Further, since the fixed catch roll portion 610 and the movable catch roll portion 650 are close to each other so as to be in contact with each other when the right rear corner portion RR and the left rear corner portion LR of the cloth w are sandwiched, the wear thereof is suppressed. It is possible to increase the durability.
