Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a filling nozzle device for a meat filling machine that fills a casing with raw meat such as roast ham, boneless ham, pressed ham, etc.

Conventional technology When filling green meat into a casing using a green meat filling machine, a tubular casing is fitted onto the filling nozzle that is fitted into the filling port of the green meat filling machine and fixed to the outer periphery of the filling nozzle. The casing is filled with the meat that is held and extruded from the filling port, but at that time, the meat that is extruded from the filling nozzle expands and the casing often comes off from the filling nozzle. In particular, automatic green meat filling machines that automate the filling operation have to stop operation when the casing comes off, which has a significant impact on work efficiency.

In order to solve the above-mentioned problems, the present applicant has provided a split nozzle piece divided into a plurality of pieces inside the tip opening of the filling nozzle, and the opening of the casing that is fitted into the split nozzle piece. The split nozzle piece presses and spreads the casing, and the split nozzle piece firmly and securely holds and fixes the casing by the fixing claw provided inside the tip opening of the filling nozzle, thereby preventing the casing from accidentally coming off during the filling operation. proposed a filling nozzle device for a green meat filling machine (Special Publication No. 59-2625)
(See Publication No. 6).

Problems to be Solved by the Invention However, the filling nozzle device according to the above application does not remove meat juice or seasoning contained in the meat lump when filling the casing with the meat lump extruded from the filling nozzle. There was a drawback that a considerable amount of the pickling liquid injected into the meat would leak from the gap between the split nozzle pieces.

Means for Solving the Problems The present invention further improves the filling nozzle device in order to eliminate the above-mentioned drawbacks, and the gist thereof is to provide a filling nozzle main body with a fixed nozzle and a fixed nozzle that is externally fitted onto the fixed nozzle. and a sliding nozzle that can move in the axial direction, and the sliding nozzle moves forward to push and spread the split nozzle piece, thereby opening the opening end of the casing fitted into the split nozzle piece. The split nozzle piece is clamped and fixed between the split nozzle piece and the holding cylinder, and is held in close contact with the outer peripheral surface of the sliding nozzle.

The casing holding cylinder 10 has ears 11 at four locations on its outer periphery, and the ears 11 are fitted onto the tip 7b of the support shaft 7 and fixed with nuts, and are spaced a certain distance in front of the fixed nozzle 2. Moreover, it is arranged concentrically with the axis of the fixed nozzle 2. A ring body 12 made of a plastic material such as nylon is fitted on the inner periphery of the rear side facing the fixed nozzle 2 of the casing holding cylinder 10, and a seal ring 13 is fitted on the inner periphery of the front side.
is fitted. The ring body 12 has an inner diameter slightly larger than the outer diameter of the single compliant nozzle 3, and is provided with an engagement groove 14 on its inner circumferential surface that engages with a locking pawl 19 of a split nozzle piece 18, which will be described later. There is. The inner diameter of the seal ring 13 is designed to be approximately the same as or slightly smaller than the outer diameter of the sliding nozzle 3. Reference numeral 15 denotes a cylinder device for reciprocating the sliding nozzle 3 in the axial direction. As shown in FIG. 1, four cylinder devices 15 are fixed to the support frame 6 at appropriate intervals in the circumferential direction, and the piston rod 16 of each cylinder device 15 is parallel to the axis of the sliding nozzle 3. It extends to a connecting plate 17 fixed to a flange 4 at the rear end of the sliding nozzle 3.

Reference numeral 18 denotes a split nozzle piece that is divided into a plurality of pieces, and in the illustrated embodiment, it consists of six pieces. As shown in FIGS. 4 and 5, each split nozzle piece 18 has a main body made by pressing a metal plate, and a tip that gradually becomes narrower from a wide middle portion 18a and extends forward in a bent manner. 18b and one narrow end portion 18G, and a locking pawl 19 is provided protruding from the outer surface of the tip portion 18b, and a rear end portion 18C.
The sleeve 20 for mounting is fixed to the intermediate part 18.
A projection 2 that locks an elastic band 24, which will be described later, on the outer surface of a.
3 is provided. In addition, the intermediate portion 18a and the tip portion 1
8b is curved to have an arcuate cross section, and in particular, the inner surface of the tip portion 18b is curved so as to closely fit along the outer peripheral surface of the sliding nozzle 3.

The split nozzle piece 18 is attached to the sleeve 2 as shown in FIG.
0 is fixed to the support frame 6 by attaching pin 2 to the bracket 21.
2, and is disposed on the outer periphery of the sliding nozzle 3 with the tip 18b protruding forward from the sliding nozzle 3 in the retracted position, and the entire split nozzle piece 18 is It is gripped by an elastic band 24 such as a rubber ring, and its elastic pressure urges the tip 18b of each split nozzle piece 18 toward the axis of the fixed nozzle 2, thereby forming a nozzle opening with a tapered end.

Next, the operation of the filling nozzle device of the present invention having the above configuration will be explained.

The tubular casing 25 is automatically or manually attached to the fixed nozzle 2.
As shown in FIG.
It stops at the position where a is fitted into the tip 18b of the split nozzle piece 18 forming a tapered nozzle opening. Next, the cylinder device 15 is activated and the sliding nozzle 3 moves forward. As the sliding nozzle 3 moves forward, the tip 18b of the split nozzle piece 18 is pushed outward in the radial direction and is pressed against the ring body 12 of the holding cylinder 10, and is locked as shown in FIG. The casing opening end 25a is clamped and fixed between the claw 19 and the engagement groove 14 with which it engages, and is firmly and reliably fixed and held. The sliding nozzle 3 further advances to the front side of the casing holding cylinder 10, and the casing 2 is attached to the outer peripheral surface of the sliding nozzle 3.
5 in close contact. At this time, the seal ring 13 presses the casing 25 against the outer peripheral surface of the sliding nozzle 3 and the casing 2
5 and the outer circumferential surface of the sliding nozzle 3 can be maintained more reliably. Further, the gap between the outer peripheral surface of the fixed nozzle 2 and the sliding nozzle 3 is also kept sealed by the seal ring 5.

In this state, a certain amount of green meat M pushed out from the filling port 1 is filled into the casing 25 through the fixed nozzle 2 and the sliding nozzle and nozzle 3 continuous thereto. Therefore, during this filling operation, the meat juice or pickle liquid contained in the meat mass M may leak from the gap between the outer circumferential surface of the sliding nozzle 3 and the casing 25 and the gap between the outer circumferential surface of the fixed nozzle 2 and the sliding nozzle 3. There is no.

Effects of the Invention As described above, according to the present invention, the split nozzle piece that clamps and fixes the opening end of the casing is pushed out in conjunction with the forward movement of the sliding nozzle fitted onto the fixed nozzle, and the opening movement of the split nozzle piece is expanded. Since the nozzle moves further forward and holds the casing in close contact with the outer peripheral surface of the nozzle, the meat juice and pickle liquid contained in the meat loaf will not leak out during the filling operation of the meat loaf.

Therefore, there is almost no loss of raw materials during filling operations.
The practical effects are extremely large. Moreover, the opening of the casing is firmly and reliably clamped and fixed between the split nozzle piece and the holding cylinder, so that it will not come off unexpectedly during the filling operation.

The filling nozzle device of the present invention, which exhibits such effects, is particularly effective when installed in conjunction with an automatic green meat filling machine that automates the supply of casings.
