Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a series of sausage ropes (hereinafter referred to as "sausage ropes") wrapped in an extruded but not yet completely cured outer shell. The present invention relates to a shearing device for tightening and cutting into small pieces, and also to a shearing method using such a device.

PRIOR ART AND PROBLEMS TO BE SOLVED BY THE INVENTION In the manufacture of sausages, immediately after extrusion or filling of the casing, or after passing the sausage rope through a brine bath, the sausage
Flying shear systems are known in which individual sausages are formed by moving a rope along the sausage lobe direction and locally tightening and cutting it. This flying shear system
They can be multiplied as required and mounted circumferentially on a continuously rotating drum, which drum is rotatable at a circumferential speed corresponding to the forward speed of the sausage rope.

Such apparatus and method are described in European Patent Application No. 013
It is known by No. 9333.

Sausages are now often coated with a non-separated, essentially sticky skin, which is extruded around ropes of meat in the form of a paste-like mixture. , which later hardens to a solid state but remains sticky and strong enough to wrap around and protect ropes of meat. This extrusion can be done simultaneously with the extrusion of the meat rope. The composition of the mantle may be of any type of composition, but preferably consists essentially of collagen as shown by Dutch Patent Specification No. 161,973. Such a sheath adheres quickly and firmly to the meat rope and is therefore
After tightening, the individual sausages will not need to be twisted to tighten the ends sufficiently before being cut off.

Also before the outer coating hardens. It will stick to it enough to tighten the sausage during tightening.

For a long time there has been a desire to produce small sausages, in particular sausages shorter than 40 m5.

However, existing machines are difficult to adapt to produce such objects due to the structure of the known shearing devices and circulating movement elements.

Regarding the production of long sausages with a natural intestine or with an artificial jacket, such as for example cellulose-based materials, US Pat. Also known from British Patent No. 246522, the two shears are arranged at a considerable distance from each other in the longitudinal direction of the sausage rope and have a common drive from a drum. , a device is provided between the two shears for a seamless belt that twists the sausage around its axis between the parts tightened by the shears, and coats the meat mixture during subsequent cutting. Tie the tightener with thread to keep it securely wrapped inside. Then, separate the adjacent knot threads of one knot.

However, this also requires a complex process and therefore cannot provide a solution to the problem of producing very short sausages.

Characteristics of the invention° The object of the invention is to provide a solution to this, and for this purpose a shearing device of the type mentioned in the preamble is arranged spaced apart when viewed from the direction of the sausage rope. One shearing blade of one of the at least two shearing shears is securely fixed relative to one of the shearing blades of the other shearing device, and the other shearing blade is also A feature is that each set of shearing blades fixed relative to another blade of another shearer and thus connected has a common drive for the shearing movement.

Additionally, the method of the present invention for tightening and cutting sausage rope into small pieces utilizes such a shearing device.

Therefore, even in the case of very short sausages, the spacing between the shear blades of each shear is relatively wide, but narrower than the spacing handled by the entire shear in the longitudinal direction of the sausage rope. It is possible to use support and drive devices.

In some known shearing devices for the same purpose as the present invention,
The length of the sausage can be varied by installing shearing devices at variable points in the structure of the circulating movement element, but this does not solve the problem of producing very short sausages.

In the present invention, one two shearing blades of each connected set of shearing blades are preferably elongated relative to the other shearing blade and are engaged with a common support and drive arrangement for the blades. This provides a very simple structure in which the support and drive mechanism for the shearing device does not need to be wider than a single shearing device.

If the shearing device of the invention is mounted on a rotating drum moving with the sausage rope in a manner known per se as described above, the shears of the device can be arranged parallel to each other, but in particular within the device If there are more than two shears, or if the sausages to be cut are not very short, it is often recommended to arrange them at an angle.

Each shearer will then be placed approximately in a plane passing through the axis of the drum.

BRIEF DESCRIPTION OF THE DRAWINGS It will become clear that the invention includes much more than what has been described above, by means of an apparatus which will be further described with reference to the accompanying drawings.

Sausage extrusion or filling machine (not shown)
From there emerges one or more sausage ropes 1 which, after being passed through a brine bath, for example, must be tightened on a drum 2 and cut into individual sausages. The drum 2 is driven and rotates around a horizontal axis at a speed that is as close as possible to the forward speed of the sausage rope 1.

On this drum, only three supporting and driving devices 3 for disconnectors are shown schematically, but the entire circumference of the drum is equipped with such devices at equal intervals. Each of the two devices 3 shown at the top includes two shearing devices spaced apart in the circumferential direction of the drum and further connected by a connecting structure 6 for drive and support from the device in question [3]. It has containers 4 and 5. A similar device 3 holding three shears 7, 8 and 9, also with connecting structure 6, is shown on the right side of the drum. Shears 4 and 5 on the same device Ea are shown parallel to each other, and shears 7
, 8 and 9 form an angle with each other, so that each of them is approximately radially arranged. The legs of the shears are
As will be explained further below, it moves in a plane orthogonal to the plane of the drawing in FIG.

At the bottom of FIG. 1, how the rope is tightened by the shears can be seen by the reference numeral 10, and the sausage cut from the rope is indicated by the reference numeral 11, said sausage being moved is collected and discharged onto a curved or sloped surface 12.

In fact, the tightening of the rope 1 takes place very gradually and begins, for example, already before the horizontal plane passing through the axis of the drum. This is to prevent the rope from falling from the drum due to its own weight.

It can be seen in FIG. 2 how the device 3 can be fixed on the drum by means of the pin 13 and the bolt 14.

The drum 2 has a number of holes evenly distributed around the circumference within the raised edge, into which the bottles 13 are fitted, and also has an equal number of threaded holes into which the bolts 14 are screwed. In this way, it is possible to mount any number of devices 3 on the drum at small or large circumferential spacings, depending on the desired size of the sausages to be cut.

In the substantially U-shaped housing of the device 13.

Two sliders 15, 16 are slidably guided and confined in the top, each slider having a sausage rope 1
The slider 15.16 has a guide roller 17.18 cooperating with a fixed guide track (not shown) adjacent to the drum formed at the periphery of the drum to be tightened and cut; accommodating unconstrained sausage ropes 1 moved in mutually opposite directions and open for most of the complete revolution of the drum for the purpose of first tightening the rope and then cutting it off; shears.

They will work opposite each other. In FIG. 2, the two shears 4 and 4' are shown in their final position for this cutting operation.

Therefore, shearers 4 with identical shears on the same circumference of the drum can process one sausage rope 1, and shears 4' on the adjacent circumference at the same time. Another sausage rope 1 can be processed. The sliders 15 and 16 are connected to the two shearers 4 and 4.
' to the same open and closed positions at the same time. Since such shearing devices are known per se, there is no need to describe them or their drive in more detail, apart from what is pointed out below.

The design of the shears becomes clear from FIGS. 3, 4 and 5. The shears 4 (7 or 4') have two shear blades 21, 22 of the form shown in FIG. The essentially flat body of the shearing blade is chamfered 23 for smooth tightening of the sausage rope, said beveled bevel serving as a cutting edge at reference numeral 24 for cutting off the tightened rope. . The shearing blades 21, 22 are of identical or nearly identical design and are arranged parallel to each other, the cutting edges 24 being arranged opposite and in contact with each other, but in other areas said shearing blades There is a slight play between them. Each shear blade is.

It is supported by a journal-bearing bushing z5 on a bushing 26 fixed around a bolt 27 between the U-shaped legs of the housing of the device 3 (FIG. 3). It can be seen from FIG. 2 that the device 3 carries two such bushings 26 and bolts 27 for each shearer spaced apart. Each of these shear blades 21 , 22 extends beyond its bushing 25 to a flat 28 with a circular head 29 at its bottom end. each head 2
9 is a slider 15.9 as shown in FIG.
16 is engaged with one of the recesses 30.

Each of the shear blades 21 , 22 has a flat projection 31 with two bolt holes 32 along the raised side opposite the tightening and cutting edge 24 .

According to the invention, two or more shears 5, 8 or 9 are installed on the same device 13, as schematically shown in FIG.

The shearing blades 33, 34 of FIG. 5 are shaped as shown in the side view of FIG. 31, but lacks the elongated portions 28, 29 and bushing 25 of FIG.

The connecting structure 6 in FIG. 1 is formed by these two flat protrusions 31 and a bridge 35 between them.

Therefore, the shear blades are connected to each other by bolts 36 passing through bolt holes 32, and the shear blades 21 are connected to the shear blades 33 (third
) while the shearing blade 22 is fixed to the bridge part 3.
5 to the shear blade 34;
It will be fixed by a screw threaded into the bridge portion 35. If it is desired to arrange the shears 5 also in a radial position that is not parallel to the shears 4.7, as shown for shears 8 and 9 in FIG.
The shear blade 34 can be provided with an angled end surface on one side or at an angle (34'), as shown by the dashed line in FIG. It can be designed as an isosceles trapezoid that can be mounted (in position).

When three or more shears are connected, such as these shears 7, 8 and 9 in FIG.
It can also be used between 1 and 9, but in this case 1
For example, from one side, it passes through the entire bridge portion 35 and bolt hole 32, passes through the flat protrusion of the central shearer 8, and is threaded into the bridge portion 35 between the other two shearers. It is desirable to use long bolts 36 that are secured by screws that are fixed by screws, then also the desired radial position on the drum of each shear. It is determined by the slope on the bridge portion 35.

Each of the connecting structures 6 with bridges 35 naturally connects only one shearing blade of each shearing device connected in this way. In order to keep the shear blades of each shear firmly pressed against each other, each upright leg of the housing of the device 3 carries a ball 39 which is preferably freely rotatable within the other end. It is possible to have a countersunk key head on the surface and the nut 38
A stud 37 will be screwed into the leg such that it can be fixed to the leg by. The studs 37 are not arranged in a straight line opposite each other, but are staggered, so that the shear blades 21, 22 are not only always well engaged due to their "inverted" arrangement with respect to each other. , it is also possible that another support device [13] is mounted very close to the one shown on the drum 2 so that adjacent studs 37 of two adjacent support devices do not interfere with each other. Something can be seen at the point of shear 4' in FIG. The unextended shear blade of FIG. 5 is configured so that it does not contact the nut 38 immediately below the edge 20.

A raised band is fixed on the left leg of the U-shaped support device 3. The raised band is located between the shears and has a flange portion 40 on its top surface with a friction-reducing coating that is harmless to the sausage casing, as shown in FIG. 3, so that the sausage rope 1 is It will be well supported between shears.

Such a flange could be mounted on a matching bearing arm between shears 8 and 9 in FIG.

(Effects of the Invention) As described above, according to the present invention, one blade set and the other blade set of each of the plurality of shears on the drum 2 are connected to each other, Since the cutting devices are driven by one driving device, the cutting devices can be installed close to each other, and the volume occupied by the driving device can be small.

Very short sausages can be easily produced in large quantities by simple means.
