Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a shutter mechanism in a cutting device for continuously feeding rod-shaped food, and more specifically, it is capable of simultaneously cutting a plurality of rod-shaped foods with high efficiency. The present invention relates to a multiple shutter mechanism that is structurally simple and compact.

2. Description of the Related Art Conventionally, as a mechanism for cutting plastic rod-shaped food continuously supplied, a regular polygonal shape as disclosed in Japanese Utility Model Publication No. 63-29443 and Japanese Patent Publication No. 1-42652 is used. A method of creating a polygonal cutting gate that expands and contracts in the center by arranging a shutter plate that linearly reciprocates along the periphery and supplies stick-shaped food toward this cutting area and tightens it. It was common. However, in this shutter mechanism, since a plurality of shutter plates must be linearly slid in different directions, the motion transmission mechanism becomes complicated, and the shutter plates are in surface contact with each other for sliding motion. There are various problems in practical use such as a large amount of power loss, and food scraps clogging the sliding portion of the surface, which eventually causes the shutter mechanism to stop working.

Therefore, the applicant of the present application has developed and applied for an apparatus for cutting the bar-shaped food by performing a simple rotational movement of each shutter body instead of a linear sliding movement (Japanese Patent Application Laid-Open No. 6-58242). -7069 publication). In this device, a plurality of shutter bodies are synchronously and rotatably arranged at equal intervals on the circumference so that the tip of each shutter body always contacts the side of the adjacent shutter body. The cutting gate that opens and closes in the center is created. In the case of this device, since the sliding portion associated with the opening and closing of the cutting gate is limited to the tip portion of the shutter body, the sliding resistance is significantly reduced and smooth shutter body operation can be realized.

By adopting the rotary shutter body in this way, the seizure of the shutter mechanism is eliminated, and it becomes possible to actually perform the cutting process of the rod-shaped food continuously for a long time. Even if the device is devised like this, due to the relationship with the extrusion speed of rod-shaped foods (especially when processing materials with large viscoelasticity), there is a limit to increasing the opening / closing speed of the cutting gate to improve processing capacity. However, it has not been possible to sufficiently meet the demand for improvement of the cutting ability due to mass production.

Up to the present, however, for the purpose of improving the cutting ability, a polygonal cutting gate formed by combining a plurality of square-flame shutter plates as disclosed in Japanese Patent Publication No. 4-52738. It is proposed that a plurality of them be arranged side by side. However, this device is a simple parallel arrangement of individual shutter mechanisms that are independent of each other. Therefore, not only is smooth cutting operation difficult due to the increase in frictional resistance of the cutting gate, Useless space is created between the shutter mechanisms of
This leads to an increase in the size of the shutter mechanism and, in turn, an increase in the size of the cutting device as a whole.

[0006]

The present invention has been made in view of the above drawbacks of the shutter mechanism of the conventional stick-shaped food cutting device, and a plurality of stick-shaped foods that are simultaneously extruded and supplied. It is a technical object to provide a multiple shutter mechanism that can simultaneously cut the shutters and has a simple structure and is compact.
