Definitions
- the invention relates to a sausage forming apparatus for forming sausages.
- a casing or other tubular membrane is filled with sausage stuffing by means of a stuffing machine.
- an intermediate space in the casing is left empty; this empty space indicates the beginning and the end of a sausage.
- the segments of the filled casing are cut to the proper length.
- Per cut-off segment the ends of the cut-off sausage are bent towards each other by hand to thus form a round, bent sausage.
- the ends of the sausage are brought, by hand, into a chpping machine, which closes off the ends of the sausage with a clip and connects the ends to one another, for instance by means of a string.
- the sausage thus formed can be processed further; it can, for instance, be dried.
- a drawback of this known method of manufacturing sausages is that it entails many operations which are to be carried out manually. As a result, the labor costs are high, and, moreover, the sausages formed are relatively irregular.
- the object of the invention is to eliminate this disadvantage by providing a sausage forming apparatus with which sausages can be formed in a short time, with great accuracy and regularity.
- a sausage is formed by clamping a stuffed sausage membrane with intermediate spaces, at the location of an intermediate space, in respective first and second clamps of a first engaging unit, which clamps are next to one another in a feeding position, and clamping a next intermediate space in respective first and second clamps of a second engaging unit, which clamps are located next to one another in a feeding position, and subsequently, by means of operating means, moving a second clamp of the first engaging unit and a first clamp of the second engaging unit from the feeding position to a closing position, in which the second clamp of the first engaging unit and the first clamp of the second engaging unit are located near to one another.

- a sausage forming apparatus in this description, forming a sausage is understood to include: cutting a stuffed sausage membrane to a desired length, bringing together the cut-offends and closing the ends which have been brought together.
- the apparatus 1 comprises a supply device 2 for a sausage string; with it, a casing or another tubular, flexible membrane is stuffed with sausage mass, while periodically leaving an intermediate space open, and subsequently released.
- supply devices are known from practice so that, for brevity's sake, a detailed description is omitted.
- the invention for that matter, is not limited to sausages; the invention can also be used with other tubular, flexible membranes, with any desired filling, edible or not.
- the supply device 2 delivers the filled casing to a feeding station 3.
- This feeding station 3 can, for instance, be manned by an operator or work entirely automatically. By means of this feeding station 3, the casing is fed into a turret station 4.
- the turret station 4 has a circular frame on which a number of engaging units, in this example twenty, are disposed in the form of engagement stations 100, which are in part represented schematically in Fig. 1.
- the invention is, for that matter, in no way limited to the number of engagement stations mentioned here by way of example; according to the invention, the number of engagement stations can be two or more.
- the invention is not limited to the circular arrangement of the engagement stations mentioned here by way of example; the invention provides for any desired arrangement in which the engagement stations are spaced apart, such as, for instance, a rectilinear arrangement.
- the engagement station has a first frame plate 101 and a substantially parallel, spaced away second frame plate 102.
- the two frame plates are arranged on the turret 4.
- two holes 103, 104, and 105, 106, respectively, are provided, while a first shaft 107 is disposed in the holes 103 and 105 and a second shaft 108 is disposed in the holes 104 and 106.
- the two shafts 107 and 108 are rotatably mounted in the frame plates 101, 102 by means of bearings.
- a gear wheel 109, 110 On each shaft 107, 108, near the second frame plate 102, a gear wheel 109, 110, respectively, is disposed in a non-rotatable manner, as is schematically represented in Fig. 2.
- the two gear wheels 109 and 110 mesh with each other.
- the first shaft 107 is provided with a lever 111, which is provided with a wheel 112 at the end remote from the shaft 107.
- the two shafts At the end situated beyond the first frame plate 101, the two shafts
- each lever 107 and 108 are provided with a lever 113, 114.
- each lever is provided with a clamp in the form of a clamping device 115, 116, respectively.
- An example of such a clamping device is shown in more detail in Figs. 3 and 4.
- the clamping device has a first jaw part 117 and a second jaw part 118, which are hingedly connected relative to one another by means of a hinge 119. In Fig. 3, the clamping device is shown in closed condition, while in the front view of Fig. 4 the clamping device is shown in opened condition.
- the first jaw part 117 has a clamping surface 120, provided with a centrally located recess 121.
- the second jaw part 118 has a clamping surface 122, provided with a centrally located projecting part 122', whose width corresponds to the recess 121, so that, in closed condition of the clamping device, the projecting part 122' of the clamping surface 122 rests within the boundary of the recess 121.
- the jaw parts 117 and 1 * 18 are provided with diverging run-in parts 123, 124, respectively, which have an angle relative to the clamping surface 120, 122 such that the feeding of a casing to be clamped proceeds readily. Subsequently, a fed-in casing is clamped between the clamping surface 120 with the recess 121 and the clamping surface 122 with the projecting part 122'. As the projecting part 122' and the recess 121 fit together as groove and tongue, a good clamping of the casing is obtained.
- the second jaw part merges into a lever 125.
- this lever 125 is pushed upwards relative to the first jaw part 117, so that, in condition of rest, the clamping device is in a clamping condition.
- the lever 125 By pushing the lever 125 against the spring pressure, the second jaw part 118 is moved from the first jaw part 117 in the direction indicated with B, so that the clamping action of the jaw parts is removed.
- Feeding a casing into the clamp takes place with the jaw parts in closed condition; by means of the spring, the jaw parts are pushed onto one another.
- the run-in parts 123 and 124 the casing can be easily brought between the jaw parts into the clamped condition described hereinabove.
- Fig. 2 there is shown the engagement station 100 with the clamping devices in the initial position; here, the levers 113 and 114 are in vertical position, the clamping devices 115, 116 being situated right next to each other. Between the clamping devices, some space is free in which a cutting device is included, as will be described hereinafter.
- the invention can also be designed such that, in the initial position, the clamping devices are situated against one another. In this position, the wheel 112 with the lever 111 is substantially horizontal. By now moving the wheel 112 upwards, the shaft 107 is rotated via the lever 111. As a result, the lever 113 moves outwards, indicated with the arrow C.
- the lever 114 As the shaft 107 is coupled to the other shaft 106 via the gear wheels 109, 111, the lever 114 also moves outwards. As there is no slip possible in the transmission which is formed by the two gear wheels 109, 110, the outward movement of the levers 113, 114 takes place simultaneously.
- the wheel 112 When the wheel 112 has moved to an upper position, the levers 113, 114 are in a horizontal orientation; in the following, this horizontal position will be designated as the closing position. It is, for that matter, not necessary that the levers are in a horizontal position in the closing position; bending the sausage can also be achieved by placing the levers at an angle with the horizontal.
- the invention is not limited to the manner of moving the clamping devices from the initial position to the clip position as mentioned by way of example here.
- the invention also provides other manners of moving the clamping devices, for instance by means of translation.
