DETAILED DESCRIPTION
[0046]
[0047] As yet another example, elements shown above/below one another, at opposite sides to one another, or to the left/right of one another may be referred to as such, relative to one another. Further, as shown in the figures, a topmost element or point of element may be referred to as a top of the component and a bottommost element or point of the element may be referred to as a bottom of the component, in at least one example. As used herein, top/bottom, upper/lower, above/below, may be relative to a vertical axis of the figures and used to describe positioning of elements of the figures relative to one another. As such, elements shown above other elements are positioned vertically above the other elements, in one example. As yet another example, shapes of the elements depicted within the figures may be referred to as having those shapes (e.g., such as being circular, straight, planar, curved, rounded, chamfered, angled, or the like). Further, elements shown intersecting one another may be referred to as intersecting elements or intersecting one another, in at least one example. Further still, an element shown within another element or shown outside of another element may be referred as such, in one example. In at least one example
[0048]
[0049] As can be seen from
[0050] The stamp elements may, however, also be configured such that they are made of a conductive material or a non-conductive material and provided with an insulating coating.
[0051] However, also the electrodes may have an insulating coating and may be exposed only at the places across which current is intended to flow to other electrodes; this means that e.g. the respective lower and/or upper end face of the opposed electrodes is exposed at least partially.
[0052] While the stamp elements extend substantially parallel to one another in the area of the electrode, the distance between the stamp elements 3a.sub.1, 3a.sub.2 and 3b.sub.1, 3b.sub.2 decreases in a forward direction, so that the respective electrode is located at a protected position. The stamp elements are also intended to center the gap between the sausage portions in this way.
[0053] As can especially be seen from
[0054] The embodiment shown in
[0055]
[0056] In the closed position shown in
[0057] The voltage supply may either be started automatically via a position switch, when the closure module 1 is at a closed position, or activated manually via a switch which is not shown. The latter may be a switch on the device or e.g. a foot switch.
[0058] According to at least one embodiment, the voltage supply takes place automatically. A measuring potential is applied between the two electrodes. Making use of the measuring potential, e.g. the resistance between the electrodes can be measured and, depending on the resistance, it can be determined whether a sausage casing is present between the electrodes. If it is determined that a sausage neck is present between the electrodes in the closure module, the voltage and/or the current and consequently the closing power will automatically be increased, in particular after an adjustable period of time.
[0059] The sausage neck serves as an electrolyte between the electrodes 2a, 2b. The current flows from an electrode 2a through the sausage neck 4 into the lower electrode 2b. When the current flows through the sausage neck 4, the electric energy is converted into thermal energy and heats the sausage neck. In natural casings the thermal denaturation of collagen, i.e. the coagulation of protein from approx. T=65 C., will then begin. A sign indicating this is a whitish discoloration. From approx. T=100 C. onwards, the water evaporates and the e.g. open natural casing or sausage neck will coagulate and be closed. In response to a further supply of energy, the temperature rises and the sausage casing decomposes; as a result, the sausage neck 4 is cut off. The decisive aspect is the heat development and the power supplied. The higher the amount of energy supplied per unit time (i. e. electric power) is, the faster the rise in temperature of e.g. the natural casing will be. If an excessive amount of power is supplied, a denaturation of the casing will not take place, but fast heating and decomposition and cutting off of the sausage neck will occur. Coagulation and closing of the division point has then not taken place. Therefore, it will be of advantage when the power is not excessively high at the beginning, so that denaturation can take place slowly.
[0060] The fact that the sausage neck is clamped by the stamp element pairs allows closing and separating in a particularly careful manner. At the rounded sausage end 6, mechanical stresses acting on the sausage casing are caused by the e.g. twisted-off division point and by the displacement of the sausage mass, i.e. the sausage meat. If a current were now introduced directly at the rounded sausage end, the sausage casing, which is under mechanical stress, might tear during heating. Due to the fact that the sausage neck is clamped before the transition to the rounded sausage end 6, the mechanical stresses are held back. The current is introduced between the stamp elements through the electrode pair 2a, 2b and flows exclusively through the sausage neck, but not through the sausage casing of the rounded sausage end, which is under mechanical stress. The clamping of the sausage neck must not be eliminated until the flow of current has ceased to exist and in particular not until denaturation has taken place, so that reliable closing will be possible.
[0061] A separation process can be initiated by briefly increasing the electric power (peak) after the electric power for closing and denaturation.
[0062] The clamping can be eliminated by moving the handle elements 7a, 7b apart. Since the closure module applies the voltage not to the filled sausages or sausage casings 5 themselves, but to a sausage neck, the closure module according to the present disclosure can also be used for closing a sausage end.
[0063] In connection with
[0064] For moving the spreading elements apart, a curved path (cam path) 12 may be provided, as can be seen from
[0065] The opposed stamp elements 3b.sub.1, 3b.sub.2 are simultaneously pivoted apart by the mechanism described hereinafter. The stamp element 3a.sub.1 is connected to the shaft by means of a pin arranged transversely to the axis A.sub.1, the center of said shaft corresponding to the axis A.sub.1. This shaft is rotatably supported in the upper handle element 7a. In addition, the lower handle element 7b has fixed therein a pin that engages the curved path 12 of the stamp element 3a.sub.1. When the two handle elements 7a and 7b are moved towards each other, also the stamp element 3a.sub.1 will be moved linearly relative to the lower handle element 7b, and the curved path 12 will, due to its Z-shaped contour, cause the stamp element 3a.sub.1 to move outwards in a pivotal movement. The shaft A.sub.1 can be moved axially within the stamp element 3b1. A pin arranged in the stamp element 3b.sub.1 transversely to the axis A.sub.1 extends through the shaft A.sub.1 in a vertically provided elongate hole, so that, although rotation can be transmitted from the shaft A.sub.1 to the stamp element 3b.sub.1, the shaft A.sub.1 is freely movable in a direction longitudinal to the stamp element 3b.sub.1. In this way, a synchronous pivotal movement with the two stamp elements 3a.sub.1 and 3b.sub.1 is produced in an inward and in an outward direction. The two stamp elements 3a.sub.2 and 3b.sub.2 move analogously thereto.
[0066] The guide shown in
[0067]
[0068]
[0069] According to at least one embodiment, the closure module 1 has two closure elements A, B, which are movable relative to and towards each other, as shown in
[0070] As can be seen from
[0071] The method according to the present disclosure will be explained hereinafter making reference to
[0072] For closing, or for closing and separating filled sausage casings 5 connected via a sausage neck 4, the closure module 1 is first placed e.g. between two filled sausage casings 5 or at an open sausage end (not shown). To this end, the opposed stamp element pairs 3a, 3b are introduced into an area between the filled sausage casings 5, such that the sausage neck 4 is placed between the electrodes 2a, 2b and the stamp elements 3a.sub.1, 3b.sub.1, 3b.sub.2, 3b.sub.2, as shown e.g. in
[0073] For the purpose of closing, or closing and separating, the stamp elements and the electrodes 2a, 2b must now be moved relative to one other, as shown by the arrow P in
[0074] From approx. T=100 C. onwards, the water evaporates and the e.g. open natural casing coagulates and is closed. In response to a further supply of energy, the temperature rises and the sausage neck decomposes and is cut off.
[0075] According to at least one embodiment, a certain amount of energy per unit time is supplied during a first time interval t.sub.1, such that the sausage neck is heated and will close, in particular coagulate. If it is also intended to cut off the sausage neck 4, a power increase, in particular a peaklike power increase, can take place during a second time interval t.sub.2. This results in fast cutting off. The current supply is then terminated either manually or automatically, e.g. after a predetermined period of time or by triggering a switch or a position switch. The electrodes 2a, 2b and the stamp element pairs 3a, 3b can then be moved apart in a direction opposite to the direction of the arrow P, so that, as shown in
[0076] Instead of manually moving the electrodes 2a, 2b and the stamp element pairs 3a, 3b towards and away from one other, they may also be moved by a positioning drive, in particular a pneumatic or an electric positioning drive. Moving the components apart can easily be accomplished by the operator loosening his grip on the handle element 7a; e.g. the elements 7a, 7b may be spring-loaded by a spring, which is not shown, (e.g. in the column guides 9), so that the position spaced apart by the distance a will automatically be re-established.
[0077] It will be appreciated that the configurations and/or approaches described herein are exemplary in nature, and that these specific embodiments or examples are not to be considered in a limiting sense, because numerous variations are possible. The subject matter of the present disclosure includes all novel and nonobvious combinations and subcombinations of the various features, functions, acts, and/or properties disclosed herein, as well as any and all equivalents thereof.
