Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a dust collecting duct attaching / detaching device for a shearing machine that sucks and collects dust such as sheared hair when shearing shearing a pile of pile fabric.

[0002]

[Prior Art]

 Conventionally, as a dust collecting device of a shearing machine for shearing a pile of pile fabric, there is, for example, a device having a structure as shown in FIGS. That is, a dust collecting duct 73 is provided which surrounds the spiral cutter 72 in the shearing machine 71 so as to surround the spiral cutter 72 above, to the side, and to the rear thereof. The dust collecting duct 73 has a front portion with respect to the spiral cutter 72 and the lower blade 74. While installing the oil felt 75 (felt impregnated with lubricating oil) for supplying lubricating oil, the dust collector hose 77, 77 and inlet hose 78 made of vinyl chloride are attached to the discharge port 76 of the dust collecting duct 73 described above. 79 is connected to the dust collector 79, the outlet hose 80 of the dust collector 79 is led out to the outside of the standing wall 81, and a plurality of back filters 82 ...

According to this dust collector, cutting hair and dust generated when the pile of pile fabric is sheared are driven by the dust collector 79 through the dust collecting duct 73, the dust collecting hose 77, and the inlet hose 78. The dust can be collected and further collected in the bag filter 82 via the outlet hose 80.

By the way, when the cutting condition by the cutter blade 83 (see FIG. 6) and the lower blade 74 of the spiral cutter 72 is deteriorated, first, the dust collecting duct 73 is removed, and the lower blade 74 and the cutter blade 83 are removed. While cleaning the cylinder, return the cylinder 84 (see FIG. 6) to the radius position 74a of the lower blade 74, apply contact pressure to rotate the cylinder 84 in the reverse direction (see FIG. 6) to the radius position 74a of the lower blade 74. The so-called sliding operation is performed in which the cutter blade 83 and the lower blade 74 are polished with polishing powder while applying a contact pressure and rotating the cylinder 84 in the reverse direction (clockwise rotation in FIG. 6).

The frequency of this rubbing varies depending on the pile fabric to be shirred, but in recent years, pile fabrics made of a material that is relatively hard to cut have tended to be used, and the rubbing frequency has also increased.

However, in the above-described conventional apparatus, the dust collecting hose 77 that is firmly attached to the dust collecting duct 73 is removed from the duct 73 as a pre-sliding operation, and is fixed to the shearing machine 71 by a large number of set bolts. It is necessary to remove the dust collecting duct 73 as a heavy object by a plurality of workers. This work requires the work on the shearing machine frame which is relatively slippery due to oil and dust. There was a problem that workability was extremely poor.

In addition, it is necessary to mount the dust collecting duct 73 and the dust collecting hose 77 in their original positions as a post-sliding operation, but when the dust collecting duct is mounted in a fixed position, the dust collecting duct is polished. In some cases, it may collide with the rear cutter blade 83. In such a case, re-grinding (re-grinding) is required, and therefore the total time of pre-work, lapping work, and post-work is extremely long. There was a problem that became.
