METHOD AND DEVICE FOR CUTTING RUBBER BALE

摘要

A horizontally positioned cylindrical fixed barrel is provided with barrel side supply ports for a rubber bale, the barrel side supply ports being disposed on a pair of barrel walls of the cylindrical fixed barrel, and an ejection port for a rubber cut piece disposed on a lower part of the barrel, and an in-barrel rotary member which rotates while being in internal contact with the cylindrical fixed barrel is provided with an inner supply ports which receive the rubber bale when they oppose the barrel side supply port as the in-barrel rotary member makes a half turn. A rotary blade for cutting the rubber bale which is fed is disposed on the rim of the inner supply port and the receiving blade which opposes the rotary blade is disposed on the rim of the barrel side supply port, and rubber bale supplying mechanisms for supplying the rubber bale to be cut to the barrel side supply port by holding the rubber bale from the upper and lower sides of the rubber bale are disposed on the outside of the barrel side supply port of the cylindrical fixed barrel.

1. A rubber bale cutting method,
using a cutting device
wherein one or a plurality of barrel side supply ports for supplying a rubber bale to be cut is disposed on a side face of a barrel wall of a cylindrical fixed barrel having a horizontally positioned axis, and the cylindrical fixed barrel is provided with an ejection port for a rubber cut piece on a lower part of the barrel, and an in-barrel rotary member which rotates by a rotation drive mechanism while being in internal contact with the cylindrical fixed barrel,wherein the in-barrel rotary member is provided with an inner supply port for receiving the rubber bale from a barrel side supply port when it opposes the barrel side supply port as the in-barrel rotary member rotates in the cylindrical fixed barrel, and a rotary blade for cutting the rubber bale which is fed into the in-barrel rotary member via the inner supply port is disposed on the rim of the inner supply port on a side which follows the movement of the inner supply port during rotation of the in-barrel rotary member so that the rotary blade opposes a receiving blade which is disposed on the rim of the barrel side supply port on a side that the rotary blade approaches when passing the inner side of the barrel side supply port of the cylindrical fixed barrel, the method comprising: supplying rubber bale from a barrel side supply port of the cylindrical fixed barrel, rotating the in-barrel rotary member in the cylindrical fixed barrel by the rotation drive mechanism, when the in-barrel rotary member rotates, cutting the rubber bale supplied from the barrel side supply port of the cylindrical fixed barrel is cut while being shaved off by the rotary blade which rotates along an inner cylindrical surface of the barrel side supply port, and sequentially ejecting the rubber cut pieces which have been cut off from the ejection port of the cylindrical fixed barrel.
