Embodiment Construction

[0020] Hereinafter, one embodiment of the present invention will be described based on the drawings.

[0021] figure 1 It is a plan view of the rubber sheet cutting device T of this embodiment, figure 2 is its stereogram. The rubber sheet cutting device (hereinafter, sometimes simply referred to as "cutting device") T of this embodiment is suitable as a device for obliquely cutting an unvulcanized rubber sheet material G constituting, for example, a pneumatic tire (not shown). use. Further, on the downstream side of the cutting device T, for example, a joining device (not shown) for joining the cut rubber sheet material G to form a long cord layer such as a carcass ply or a belt layer is provided. On the upstream side of the cutting device T, for example, a rubber extruder for continuously molding the rubber sheet material G or an applicator for supplying the rubber sheet material G to the cutting device T is provided (not shown).

[0022] The rubber sheet material G is a...

Abstract

The present invention provides a rubber sheet cutting device capable of enabling a feeding angle to change at high accuracy for performing cutting even for rubber sheets with different qualities. The rubber sheet cutting device (T) comprises a slant cutter device (1) and a feeding conveyer (2) for feeding rubber sheet material (G) to the slant cutter device (1). The slant cutter device (1) has a workbench (3) having a loading surface (5) for loading the rubber sheet material (G). The feeding conveyer (2) is configured to be capable of moving horizontally around a vertical axis (1C) at the periphery of the workbench (3), so that the feeding angle of the rubber sheet material (G) can change relative to the cutter. The workbench (3) comprises a pneumatic workbench part (10) having an air supply device (11) which enables the rubber sheet material (G) to float from the loading surface (5) through air supply. The air supply device (11) has an air regulation member (11b) which changes the air volume according to the quality of the rubber sheet material (G).

Description

technical field [0001] The present invention relates to a rubber sheet cutting device capable of producing, for example, a rubber sheet used in the manufacture of tires. Background technique [0002] Patent Document 1 below describes an apparatus for producing a rubber sheet in which both end edges are obliquely cut with respect to the longitudinal direction by sequentially cutting a long rubber sheet material obliquely from the end side. This device includes: an oblique cutter that moves up and down on a fixed table to cut the rubber sheet material; and a conveyor that supplies the long rubber sheet material to the table. The conveyor can move horizontally around the fixed table with any vertical axis as the center. [0003] Such a device can change the feeding direction of the rubber sheet from the conveyor with respect to the diagonal cutter, so that the angle formed by the end edge of the rubber sheet and the longitudinal direction, that is, the skew angle, can be chang...
