Abstract

(57) [Summary] (with amendments) [Purpose] To prevent the fibrous material from remaining as drips on the edge of the filling nozzle outlet when filling a quantity of material containing a large amount of fibrous material. The purpose is to [Structure] The filling nozzle 9 is characterized in that one or more annular grooves 9a and 9b are formed near the inner surface outlet.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to an improvement of a drip prevention device in a filling machine of a packaging machine.

0002

[Conventional technology]

Food packaging is becoming increasingly diverse these days, and there are a wide variety of fillings, but especially If fibrous items such as meat, onions, or Chinese cabbage are stewed, the filling should be done at the end of filling. At the nozzle exit, liquid drips toward the inner and outer surfaces of the seal of the bag. The liquid drips Not only does it reduce the product value, but if it adheres to the nozzle etc., it mixes with other types of fillers. Moreover, it also has a negative impact on hygiene and requires time and effort to clean the inside of the device. The present applicant has developed a device as shown in FIG. 2 to prevent the above-mentioned dripping. It was proposed as No. 72158.

0003 This device transfers the filling in a storage tank 1 to a measuring cylinder by switching a switching valve 2. The bag is extruded by the piston punch 3a of No. 3, and the bag is filled from the filling nozzle 9 through the supply path 10. 12, and when a predetermined amount is filled, actuate the actuating cylinder 6 to open the filling nozzle. In a filling machine in which the supply is stopped by pushing down the supply stop rod 7 in 9, The piston rod 6a of the operating cylinder 6 and the supply stop rod 7 are connected by springs 8a, 8. In this device, the actuating cylinder 6 is connected via the When the filling material is supplied by moving the supply stop rod 7 down, the springs 8a and 8 As the supply stop rod 7 repeatedly moves up and down in response to the elastic vibration of b, the supply path is closed. 10 and the filling nozzle 9 at the boundary line 10a etc. It is something that

[Problem that the idea aims to solve]

The above device can effectively wipe away dripping from the nozzle tip. However, if the filling contains a particularly large amount of fiber, it may be necessary to cut the fiber. Since the location is limited to the tip edge 10a of the supply channel 10, the fibrous material is relatively long. Those that have turned to the supply path 10 side slide down the inner surface of the filling nozzle 9 and become viscous. When the adhesion is strong, it can cause another drip 13 that gets caught as shown in Figure 3. There is.

[0005]

[Means to solve the problem]

This invention aims to solve the above problems in a new way, and its features are as follows: The filter has one or more annular grooves formed near the inner surface outlet of the filling nozzle, and the groove edge This is because a separate location is provided between which the fibrous material is cut while being compressed.

[0006]

[Effect]

Since one or more annular grooves are formed near the outlet on the inner surface of the filling nozzle 9, the supply The fibrous material that slides down without being cut at the road exit is stored at the annular groove position. It is cut by being pinched between the tip of the feed stop rod and the edge of the annular groove, and is fed into the bag. Even highly adhesive and relatively long fibrous substances can be attached to the nozzle outlet end. No more lingering residue after wearing.

【Example】

Embodiments of the present invention will be described with reference to the drawings. Figure 1 is a sectional view showing the main parts of the present invention. The rest of the device configuration is the same as that of the conventional technology shown in Figure 2, so it is omitted. Omitted.

[0008] As shown in Fig. 1, in the present invention, the supply path on the metering cylinder 3 side is One or more annular grooves 9a, 9b (in the illustrated example, two Let them form (individuals).

[0009] Next, the effect will be explained. The filling g in the storage tank 1 is When the actuating cylinder is supplied into the bag 12 from the filling nozzle 9 through the supply path 10, The feeder 6 is activated to push down the supply stop rod 7 to stop the supply. The stop rod 7 is moved inside the filling nozzle 9 under the action of the elastic vibrations of the springs 8a and 8b. The filling material accumulated near the outlet end 10a of the supply channel is cut by repeatedly moving up and down. , If there is a part that slides down without being cut, stop the supply at the annular grooves 9a and 9b. It is squeezed between the tip of the retaining rod 7 and the circumferential edges of the annular grooves 9a and 9b to produce a new cutting action. receive.

0010

[Effect of the idea]

As mentioned above, in the present invention, an annular groove is formed near the inner surface outlet of the filling nozzle 9. Therefore, combined with the elastic vibration action of the spring, the filling material contains a large amount of fibrous material. Even with highly viscous materials, the new cutting action makes dripping even more effective. It becomes what is intended.
