Reference numeral 4 is a cylinder whose tip is opened and closed by the switching valve 3, and 5 is a piston for extruding viscous seasoning,
A certain amount of a viscous seasoning (not shown) in the tank 1 is sucked into the cylinder 4 in accordance with the opening / closing cycle of the switching valve 3, and is extruded from the nozzle 7 through the passage 6 to the outside.

Reference numeral 8 is a passage 6 between the switching valve 3 and the nozzle 7.
Is a cylinder whose tip is opened at a predetermined position in the middle of, and has a smaller diameter than the cylinder 4, and has a viscous seasoning dripping prevention piston 9 built therein, and
The viscous seasoning dripping prevention piston 9 is constantly pushed rightward in the drawing by a spring 10.

Reference numeral 11 is a crank in which one end of a crank rod 13 is connected to one end of a rod 12 of a piston 5 for extruding a viscous seasoning, and a cam floor 14 whose mounting position can be appropriately adjusted is attached to the crank 11. .

Reference numeral 15 is a link whose upper end is pivotally attached to a proper position of the machine frame 16 so as to be constantly in contact with the cam floor 14, and one end of the rod 15 of the viscous seasoning dropping preventing piston 9 is provided at the lower end of the link 15. The other end of the pivotally attached link 18 is pivotally attached. In addition, the link 18 and the rod 17 are provided with an adjusting screw portion 19 so that the connecting interval can be adjusted appropriately.

Reference numeral 20 is a cushioning leaf spring provided at an appropriate position of the machine frame 16 so as to receive the link 15.
21 is a guide for the rod 12 and the crank rod 13, 22
Is an adjusting screw portion that can appropriately adjust the connection distance between the rod 12 and the crank rod 13, and 23 is a guide for the rod 17. One end of the spring 10 is attached to the machine frame 16, and the other end of the spring 10 is attached to the link 15.

The operation of the viscous seasoning filling machine configured as described above will be described. In the state shown in the drawing, a certain amount of the viscous seasoning in the tank 1 passes through the passage 6 by the viscous seasoning pushing piston 5. When extruded from the nozzle 7 to the outside, in this case, the tip of the viscous seasoning dropping preventing piston 9 provided in the middle of the passage leading to the nozzle 7 is also located on the rightmost side in the drawing.

In this state, the switching valve 3 has the arrow a.
When the cylinder 1 of the viscous seasoning extruding piston 5 is disconnected from the passage 6 and the tank 1 is connected to the cylinder 4, the viscous seasoning extruding piston 5 follows the rotation of the crank 11 as shown in FIG. Moving to the left, the viscous seasoning in the tank 1 is accommodated in the cylinder 4, but at this time, the cam floor 14 is attached to the crank 11, and the cam floor 14 allows the links 15, 1 to be connected.
8. Since the viscous seasoning dropping preventing piston 9 in the cylinder 8 is moved leftward against the tensile force of the spring 10 through the rod 8 and the rod 17, a negative pressure is applied to the opening end of the nozzle 7, that is, toward the passage 6 side. The suction force acts to prevent the viscous seasoning from dripping from the tip of the nozzle 7.

[0010]

However, in the above-described conventional viscous seasoning filling machine, the viscous seasoning discharge port of the nozzle 7 is formed small in order to improve the effect of preventing liquid dripping. Therefore, in the case of a viscous seasoning in which a granular seasoning is mixed, not only there is a problem that the granular seasoning is clogged at the opening end of the nozzle 7 and the filling is hindered. There is a problem that it takes a long time to fill and high-speed filling cannot be performed.
