Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for filling a casing with raw meat such as fish meat or meat, twisting the casing at a predetermined length to form a filling portion, and producing a chain-shaped sausage or the like. Regarding

[0002]

2. Description of the Related Art An apparatus of this type is disclosed in, for example, Japanese Patent Laid-Open No. 11-1
It is known in Japanese Patent Publication No. 00 and Japanese Patent No. 2612491. There, a nozzle for filling the casing with the raw meat, a pump for supplying the raw meat to the nozzle, a chuck for twisting the casing filled with the raw meat, and a casing fed from the chuck are sandwiched and cooperate with the chuck. And a link forming device for forming a filling portion having a predetermined length. The link forming device consists of a pair of chain mechanisms that are arranged adjacent to each other in parallel, and around the chain,
Claw pieces (pinchers) that define the length of the filling portion are fixed at regular intervals. The pump there is a gear pump.

[0003]

In the above sausage manufacturing apparatus, the length of the filling portion is defined by the distance between adjacent claw pieces provided on the circumferential surface of the chain. Therefore, it is necessary to replace the chain of the link forming device each time the size of the filling portion is different, and it takes a lot of trouble to perform the setup change. It is necessary to prepare several types of chains according to the number of types of products with different lengths of the filling section, and the introduction cost (several 100,000 yen per unit) is high. Since the raw meat is fed under pressure by a gear pump, when filling the coarsely ground meat, the chunk of meat is crushed into small pieces or crushed, and the texture peculiar to the coarsely ground meat is likely to be impaired.

The object of the present invention is to eliminate the need to carry out setup changes such as changing or exchanging chains even when the lengths of the filling parts are different, so that the time and labor required for setup changes can be saved, and sausages and the like can be saved. An object of the present invention is to provide a sausage manufacturing apparatus capable of efficiently manufacturing foods and easily manufacturing products having different lengths of filling portions. An object of the present invention is to provide a sausage manufacturing apparatus capable of freely setting the length of a filling portion and, if necessary, easily manufacturing sausage or the like in a state where filling portions having different lengths are mixed.

[0005]

As shown in FIG. 2, the apparatus of the present invention comprises a pump 1 for feeding raw meat under pressure, and a pump 1.
A nozzle 3 that is communicated with the feed port 2 of the casing 3 and fills the raw material meat into the casing C, and the casing 3 by rotating the nozzle 3.
Chucks 5R and 5L for twisting the knotting portion 4, a sorting device 6 for defining the length of the filling portion filled with raw meat, and a feeding device 7 for feeding the chained sausages sent from the sorting device 6. Is equipped with. As shown in FIG. 1, the sorting device 6 includes a pair of winding mechanisms 35 arranged to face each other with a casing C in between, a sandwiching blade piece 36 protruding from the outer surface of each winding mechanism 35, and each winding mechanism. And a drive mechanism 37 for intermittently rotating and driving 35. Thus, the casing C is sandwiched and closed by the pair of sandwiching blades 36 to form the knot 4 in the casing C.

Each winding mechanism 35 includes a pair of sprockets 38.
And a chain 39 wound around both sprockets 38. As shown in FIG. 7, the sandwiching blade pieces 36 fixed to the outer surface of the chain 39 of each of the winding mechanisms 35 are formed with escape recesses 40 at the opposite edges thereof, which allow the knot portions 4 to be twisted and deformed. The two winding mechanisms 35 are arranged so that the line connecting the centers of the two sprockets 38 is substantially orthogonal to the central axis of the nozzle 3.

A vane pump can be used as the pump 1 for feeding the raw meat under pressure.

A feeding device 7 for feeding a chain of sausages
Is composed of a pair of winding and feeding bodies 49 arranged opposite to each other with a chain of sausages in between, and a drive mechanism for feeding and driving these winding and feeding bodies 49 in one direction.

[0009]

According to the present invention, the sorting device 6 is provided separately from the feeding device 7, and the sorting device 6 having the pair of winding mechanisms 35 is driven intermittently to sandwich the sandwiching blades 36 of the both winding mechanisms 35. Then, the casing C is sandwiched and closed to form the knot portion 4. Therefore, the pair of wrapping mechanisms 3 corresponds to the change in the length of the filling portion.
The sausage having the filling portion of an arbitrary length can be easily manufactured only by controlling the rotation timing of 5 and changing and setting the holding timing of the holding blade piece 36. There is no need to change or change the chain, which is indispensable in conventional equipment, and the cost of preparing multiple types of chains can be saved, and the time and effort for changeover can be saved. Productivity of sausages is improved as much as possible. If necessary, even a sausage having mixed filling parts of different lengths can be easily manufactured.

The winding mechanism 35 is attached to a pair of sprockets 38.
And a sprocket 38 and a chain 39 wound around the sprocket 38, and the sandwiching wing piece 36 fixed to the outer surface of the chain 39.
When the casing C is sandwiched and closed by, the filling portion can be reliably fed to the feeding device 7 without applying an excessive external force. When the relief recesses 40 that allow the twisting deformation of the knot portions 4 are formed at the opposite edges of each of the sandwiching blade pieces 32, the knotting portions 4 and the sandwiching blade pieces when the knot portions 4 are twisted by the chucks 5R and 5L are formed. Since the friction with 32 can be reduced, the twisting operation can be performed smoothly. For example, when the winding mechanism 35 is provided with a plurality of sandwiching blades 32, the minimum length of the filling portion is limited, but the line connecting the centers of both sprockets 38 is the central axis of the nozzle 3. According to the partitioning device 6 in which the winding mechanism 35 is arranged so as to be substantially orthogonal to the above, there is no previous restriction, and a short filling portion to a long filling portion can be freely formed.

When the raw material meat is pressure-fed by the pump 1 composed of the vane pump, the raw material lump is crushed by the feeding action of the pump 1 as compared with the case where the gear pump is used,
Alternatively, since it is possible to reliably prevent the meat from being crushed, when filling the casing C with the raw meat, it is possible to fill the raw meat in the raw meat state and maintain the texture peculiar to the raw meat.

According to the feeding device 7 in which the chain-shaped sausages are fed by the pair of the winding and feeding bodies 49, the chain-shaped sausages are sandwiched between the straight peripheral surfaces of the winding and feeding body 49. That is, the sausage can be fed and operated in a state where the contact area between the winding feeder 49 and the chain-shaped sausage is large, and the gripping start portion of the winding feeder 49 is brought as close to the sorting device 6 as possible to make the raw material. The filling portion in the middle of being filled with meat can be quickly pinched and captured. Therefore, compared with the conventional link forming device, it is possible to reliably prevent the abnormal load from concentrating on the knot portion 4 and causing the elongation deformation, damage, or the like of the knot portion 4, and to prevent the chained sausage from being filled. It is possible to eliminate the occurrence of defects during sending to the next process.

Next, the operation of each device will be described. The filling of the raw material meat into the casing C is performed by the pump 1 and the nozzle 3, the feeding operation of the filling portion by the feeding device 7 performed in parallel with the filling operation, the sorting operation of the filling portion by the sorting device 6, and The twisting of the knotted portion 4 by the chucks 5R and 5L is set as one cycle, and these are repeated to continuously produce sausage. In the state where one cycle is completed, as shown in FIG. 1, the knot portion 4 is sandwiched between the pair of sandwiching blades 36 between the blades 36. In this state, the feeding device 7 is operated, and at the same time, as shown in FIG. 9, while the winding mechanism 35 is rotated in synchronization with the feeding device 7, the raw material meat is extruded from the nozzle 3 and filled in the casing C. At this time, depending on the amount of raw meat to be filled,
Although it is necessary to change the length of the filling portion to a large or small size, the winding mechanism 35 of the sorting device 6 is intermittently driven to rotate in response to the filling of a prescribed amount of raw material meat, and a pair of sandwiching blade pieces is provided. By sandwiching the end of the filling portion with 36, the filling portion having a predetermined length can be divided to form the knot portion 4. In this state, the left and right chucks 5R and 5L are simultaneously driven to rotate in the same direction, so that the divided knot portions 4 are twisted. At this time, since the filling portion on the delivery side is vertically fixed by the feeding device 7, it does not rotate when the knot portion 4 is twisted.

As described above, when the sorting device 6 is provided separately from the feeding device 7, the pair of winding mechanisms 36 provided with the sandwiching blade pieces 36 are intermittently driven to divide the filling portion. The length of the filling portion can be freely changed only by controlling the rotation timing of the mechanism 35. Therefore, it is possible to omit the work of changing or exchanging the chain depending on the difference in the length of the filling portion, which is indispensable in the conventional apparatus of this type, and the labor and time for the setup change can be omitted. Further, since it is not necessary to prepare several types of chains according to the number of types of products, the facility cost can be reduced accordingly. If necessary, even a sausage having mixed filling parts of different lengths can be easily manufactured.

FIG. 10 shows another embodiment of the winding mechanism 35. There, a line connecting the centers of both sprockets 38 is provided parallel to the central axis of the nozzle 3, and the winding mechanism 35
Is different from the above-mentioned embodiment in that it is horizontally long. When the winding mechanism 35 is horizontally long as described above, the winding mechanism 35 can cooperate with the feeding device 7 to feed the filling portion. Since the other parts are the same as those of the previous embodiment, the same members are designated by the same reference numerals and the description thereof is omitted. When the idea of this embodiment is further developed, the partitioning device 6 can be configured such that the line connecting the centers of both sprockets 38 is inclined with respect to the central axis of the nozzle 3.

In addition to the above embodiment, the holding blade pieces 36 may be detachably connected to the chain 39 so that various holding blade pieces 36 can be exchangeably attached to the chain 39. The winding mechanism 35 can be configured by using a timing belt as a transmission element. The winding feeder 4 of the feeding device 7
The chain 9 may be a chain or a flat belt other than the timing belt. If necessary, a plurality of roller groups may be arranged adjacent to each other to form the feeding device 7. Feeder 7
If an automatic rod hanging mechanism is installed continuously at the end of feeding
It is possible to automatically perform a series of operations from filling sausage to hanging. As the pump 1, a two-leaf type pump can be applied in addition to the vane pump, and in some cases, a raw material meat may be fed by a gear pump.
