[0002]

2. Description of the Related Art Conventionally, as a food delivery device as described above, there is one disclosed in Japanese Utility Model Publication No. 1-11036.
As shown in FIG. 4, this food delivery device is constructed by superposing the inner material extruder 1 on the vertical axis for pushing the inner material 3 downward and the outer circumference of the inner material 3 extruded in a columnar shape from the inner material extruder 1. A horizontal axis external material extruder 2 for extruding the external material 4 is provided.

Further, a passage wall 6 of the inner material 3 extruded from the inner material extruder 1 is vertically fixed to the main body frame 5.
Further, a substantially cylindrical capacity control chamber 7 whose upper surface is closed is formed on the outer periphery of the passage wall 6 in the main body frame 5, and the outer material extruder 2 is pushed through the communication passage 8 on the outer periphery of the control chamber 7. Exit 9
Are connected. The outer material guide cylinder 10 is concentrically arranged on the outer peripheral side of the passage wall 6 and fixed to the main body frame 5 side, and is connected to the lower end of the inner peripheral portion of the control chamber 7 between the passage wall 9 and the guide cylinder 10. An outer material passage 11 is formed, a runner 12 is arranged on the outer peripheral side of the guide cylinder 10 concentrically with the passage wall 9, and several blades 13 for feeding the outer material 4 are provided on the upper surface of the runner 12 below the inner peripheral side. 13 is arranged in the control chamber 7, the runner 12 is rotatably supported on the lower portion of the frame 1, and the electric motor 14 for rotating the runner 12 is arranged outside the control chamber 7 to form an external material feeding mechanism.

The food delivery apparatus having the above-described structure operates the inner material extruder 1 and the outer material extruder 2 and also drives the electric motor 14.
Is driven to rotate the runner 12, and the outer material 4 horizontally extruded by the outer material extruder 2 is attached to the outer periphery of the inner material 3 extruded downward by the inner material extruder 1 to the runner 12.
The blades 13 are rotated and sent from each part in the outer peripheral direction of the control chamber 7 with a substantially uniform pressure so as to turn downward, and the outer material 4 is superposed on the outer circumference of the inner material 3 and sent out as a two-layer columnar body. . Then, the columnar body sent out is supplied to a forming and cutting device, and is formed so as to wrap the inner material with the outer material,
It is to cut.

[0005]

The conventional food delivery device described above uses the screw of the external material extruder 2 for the external material 4.
Since the outer material 4 is forcibly extruded, an excessive pressure is applied to the outer material 4, and in this state, each portion of the delivery device is contacted, which deteriorates the quality of the outer material, and when the outer material mainly uses flour, There was a problem that the deterioration of quality was particularly remarkable.

Furthermore, the external material extruder 2 having a screw
And the runner 12 having the blades 13 are used to send out the outer material 4, the structure of the outer material feeding mechanism becomes complicated,
In addition to being expensive, there is a problem that the work such as assembling, disassembling and cleaning is troublesome.

By rotating the feeding roller of the outer material feeding mechanism, the outer material in the outer material hopper is fed between the blades of the runner mainly by its own weight by the rotation of the outer material feeding mechanism, and the outer material that does not fall by its own weight is pushed down by the feeding roller rotating at low speed with almost no compression force Send to. At this time, the outer material is scraped by the blades of the runner, and the outer material is fed downward from each portion in the circumferential direction with a substantially equal pressure, and the fed outer material is superposed on the outer periphery of the inner material and fed further downward as a columnar body. It is a thing.

The external material feeding mechanism according to the present invention is
Without using a screw like the conventional external material extruder,
The outer material is sent between the blades of the runner by its own weight, and the outer material that does not fall by its own weight is sent downward by the non-circular delivery roller, so this delivery roller should be rotated at a low speed, without applying unnecessary force to the outer material, Further, it suffices to scrape a required amount of the external material by the rotation of the runner and send the external material downward, and there is no need to apply extra pressure to the external material to bring it into contact with each part of the external material feeding mechanism. Therefore, it is possible to prevent the deterioration of the quality of the outer material, and it is possible to send out the outer material having high quality even if the outer material is mainly made of wheat flour.

Further, in this invention, in place of the external material extruder, a non-circular cross-section feeding roller having a spline shaft-shaped uneven line or an elliptical cross-section is laterally suspended in the lower part of the external material hopper. It has a simple structure and can be provided at low cost, and can be easily assembled, disassembled, and washed.
