    Description I. Field of application The invention relates to the compression of elastic and / or plastic products, such as foods, preferably a meat strand. II. Technical Background [0002] The focus here is less on compressing the product, but rather on shaping the most strand-shaped product to a predetermined cross-section, which should still be present in the end regions of the strand. On the contrary, excessive compression of the product is undesirable because these products are mostly natural products whose internal structure would be destroyed by over-compacting.
    A meat strand, for example, should have a predetermined over the entire length, constant cross-section, because it should then be sliced from him, which should have a given weight.
    Since accurate weight discs can only be created by the thickness is controlled, but the cross section of the meat strand is known, the meat strands must have a predetermined and always over the entire length of the meat strand same cross-section when slicing.
    In this context, combined press / cutting machines are already known, which press the meat strand in a machine and in one operation and perform in the compressed state of a immediately following positioned on the mold cutting unit. Of course, such a combined machine requires a much more complex structure than individual machines for pressing on the one hand and cutting on the other hand.
    There are applications in which - either very large amounts of meat strands should be cut and / or - if for the deformation - depending on the product, such as the type of meat - a considerable holding time is needed especially in cross-pressing, so the product and the pressure produced therefrom retains its cross-section at least over a certain period of time and does not immediately re-deform after removal of the pressure.
    In such cases, it may be useful to perform the pressing, ie preforming, the meat strand on the one hand and slicing on the other hand in two separate operations and in particular separate machines.
    In this case, a separate press is needed. III. DESCRIPTION OF THE INVENTION a) Technical Problem It is therefore the object of the invention to provide such a generic press which is capable of applying high pressures and nevertheless has a simple structure and is very narrow at least in one direction of extent builds to save space next to a cutting machine for slicing the meat strand or other processing machine can be set up. b) Solution to Problem [0010] This object is achieved by the features of claims 1 and 16. Advantageous developments emerge from the subclaims.
    This object is achieved in a generic press for pressing elastic and / or plastic products, which compresses both in the longitudinal direction and in a first transverse direction and having the necessary components, achieved by the following improvements are made: [0012] On the one hand, the drive of the longitudinal press ram, usually likewise a working cylinder, likewise is not arranged in an aligned manner on the rear side facing away from the pressing surface of the longitudinal press ram, but is displaced laterally, preferably laterally, parallel to the piston rod of the longitudinal press ram. to the mold and in their length range.
    This reduces the size significantly compared to a classic, aligned with the feed direction of the longitudinal press-stamp, arrangement of the acting longitudinal compression drive, usually a threaded spindle.
    Specifically, there is the drive for the longitudinal punch in the length range between the loading end face of the mold and the rear end of the piston rod of the longitudinal press ram when it is withdrawn so far that it is just inside the mold, in particular the rear end of the mold.
    Another possible measure - which can also be combined with the former - is that the transverse punch on a laterally, so in a second transverse direction, rest over the mold protruding yoke or may be attached, or even with such a yoke can be functionally unified and in particular integrally formed with this.
    This makes it possible, this transverse punch not by a drive - usually a threaded spindle -driven, which is arranged on the side facing away from the pressing surface of the transverse press ram back, which yes the size and especially in an upward open recess the height of the machine greatly enlarged, but laterally next to the mold to be arranged at about their height by each attacking on each side of the yoke and thus on both sides of the mold a working cylinder, which together with the yoke forming a portal, and whereby the size of the Press remains low.
    The cross punch is in the view of the approximately U-shaped in cross-section - ie a bottom and two lateral, mutually parallel, flanks having - recess of the mold considered yes narrower than this, so that he product-tight in this recess fits. By "product-dense" it is to be understood in this context that the gap between the lateral surfaces of the cross-press die and the flanks of the recess is too small to squeeze through portions of the product, yet quite large enough to trap trapped air in the die or liquid to escape during pressing from the mold.
    The same applies to the distance of the side surfaces of the longitudinal press die to the surrounding inner surfaces of the mold during pressing and / or for the distance of the stop plate to the end face of the mold in schlies-send state of the stop plate, which will be explained later.
    In this press usually protrudes - even in the retracted position - neither the transverse punch and certainly not the longitudinal punch completely out of the U-shaped recess of the trough-shaped die, so that the pressing space so always around the circumference Is closed longitudinally and at the rear end, the press end, always closed by the longitudinal press die.
    Therefore, both the loading and unloading of the press is preferably done only by the front, frontal opening of the press room, the loading end face, ie from the loading end of the press mold ago. Alternatively, the loading could also be done by the exposed top of the trough-shaped mold.
    This is also possible in a simple manner in the form of a first solution by either front as the loading conveyor and unloading conveyor, so in its transport direction switchable conveyor with its surface at about the height of the Bottom of the U-shaped recess is arranged in front of the mold.
    A second solution is, before the loading end of the mold objected to each other separately to arrange a feed conveyor and a discharge conveyor, but preferably both do not reach up to the loading end of the mold.
    In particular, the two conveyors are viewed in plan view aligned with the U-shaped, channel-shaped, recess arranged one above the other, of which preferably the former above the height level of the ground and the latter is below the height level of the bottom of the channel-shaped recess in the mold.
    Because in the resulting gap a slide or a switching conveyor is arranged in front of the mold-side end of the channel-shaped recess so that their - in a first variant only - top on which a product can be transported, the gap between the loading end of the Bottom of the mold and optionally the top of one of the two conveyor closes. Preferably, for this purpose, the sliding chute or the switching conveyor can be pivoted about a pivot axis.
    In spaced above each other arranged feed conveyor and discharge conveyor extends in this first variant, this pivot axis in the first transverse direction and is preferably located close to or at the mold-side end of the slide chute or the switching conveyor, so that their other end between the feed conveyor and discharge conveyor back and forth can be crossed.
    In a second variant, the shift chute or the switching conveyor comprises two superposed switching slides or switching conveyor on which a product can be transported.
    In this second variant, this pivot axis also extends in the first transverse direction and is preferably arranged close to or at the formabgewandten end of the slide chute or the switching conveyor. As a result, the front end of the upper side, ie transport surface, optionally the upper or the lower sliding chute or the switching conveyor, are brought into alignment position in front of the loading end of the bottom of the mold.
    Preferably, the transverse die and the die extend in the longitudinal direction over the same length, but at least the longitudinal extent of the transverse die is at least 70%, better at least 80%, better at least 90%, the same as the the mold, and / or the mold is preferably arranged with its open longitudinal side facing up, although this is not absolutely necessary for the realization of the invention.
    The direction of movement of the transverse punch, which can move more or less into the channel-shaped recess of the press mold, is referred to as the first transverse direction and the direction of movement of the longitudinal press
    Stamp as longitudinal direction. As a result, in the present case, the third spatial direction, which is perpendicular to the first two directions, is referred to as the second transverse direction.
    Also, the one or preferably the plurality, namely present at each protruding end of each yoke, transverse drives for the transverse press die are within the length range of the mold.
    Preferably, the yoke, which is mounted transversely on, preferably over, the transverse ram, designed as a portal, the free-ending leg extending along different sides of the mold.
    As a transverse press drive in particular threaded spindles are suitable, of which, for example, a threaded sleeve is fixed to the yoke or the free-ending leg of the portal, into which a threaded rod is screwed, which preferably in turn has a pinion at its free end.
    The pinion of all threaded rods can be set in synchronism by a common central gear, which is then preferably below the mold and in its length range, and the gear can be driven with only a single electric motor.
    Ideally, the transverse ram is retracted during the longitudinal compression to such a position in the mold, that the remaining cross section is just slightly larger than the cross section of the longitudinal press ram.
    Since this is not always very exactly possible, the longitudinal pressing punch is preferably variable in size in the first transverse direction, the transverse pressing direction, e.g. formed in two parts with two intermeshing parts, which are biased spring-loaded in the direction of moving apart, so that the free cross-section of the pressing chamber is always filled sufficiently completely by the longitudinal press die.
    The longitudinal pressing ram is preferably releasably attached to the piston rod, since it is a wear part on the one hand, on the other hand may be made possible by different degrees of retraction of the cross press ram different cross-sections of the pressing space during pressing.
    The longitudinal press die is either force-controlled or position-controlled. In the latter case, a position sensor is present on the longitudinal press unit, either on the piston rod or on the longitudinal press die, and the position of the longitudinal press die is reported to the controller.
    In the case of a force-controlled longitudinal pressing punch, a force sensor or pressure sensor is provided which measures with which force or pressure the longitudinal pressing punch presses against the product. This may, for example, be a sensor which reduces the current consumption of the longitudinal ram, e.g. via a threaded spindle driving motor, or this may be in a longitudinal press drive in the form of a working cylinder, a pressure sensor which measures the pressure inside the working cylinder.
    In any case, the piston rod preferably corresponds in length at least to the length of the mold, in particular less the length of the longitudinal press ram measured in the longitudinal direction.
    As already stated above based on the concrete drive of the cross-press ram over threaded spindles, all existing yokes can be applied via traverses or portals together by a single cross-press drive, which the cost of different components and thus the complexity of Press greatly reduced.
    Preferably, the mold and / or the transverse press die and / or the longitudinal press die have a vent that can open or close a connection between the press cavities and the environment, and with the aid of which the press room can be vented to to let escape the air still present at the beginning of pressing in the press room, if the gaps between the press dies and the surrounding mold in the forgotten state are not sufficient for this.
    When pressing in the longitudinal direction of the longitudinal pressing die presses the product in the longitudinal direction against a front, loading side end face of the press room closing stop plate, preferably along guides either from its own drive or one of the other existing drives by means of a corresponding coupling, can be moved back and forth between an open position and a closed position. In the open position, the stop plate, the end face of the press room completely free, including the maximum possible cross section at the maximum far retracted Querpressstempel in which this is just over a small distance within the mold.
    In the closed position, the stop plate, which bears directly against the face, as close as possible to the die, closes the cross-section of the press space completely.
    In this way, dimensions of the press can be achieved which are very compact.
    Thus, the transverse drive and / or the longitudinal drive considered in the longitudinal direction can be within the width range of the mold and / or maximum in this transverse direction only over a width of at most 70 cm, better at most 60 cm, better at most 50 cm, better at most Extend 45 cm.
    Preferably, at least the transverse drive, and / or the longitudinal drive are at a height level below the mold.
    Thus, the longitudinal drive comprise a threaded spindle, in particular a ball screw, or a working cylinder whose direction of movement in the longitudinal direction preferably extends below the mold and a longitudinally movable carriage, which is movable along a longitudinal guide, and on the one hand with the working cylinder and on the other hand connected to the piston rod.
    The carriage may be shaped in particular in the side view L-shaped, and that free end of the transverse leg of this L-shape be connected to the free rear end of the piston rod.
    The cross-sectional contour of the channel-shaped recess in the mold may have a bottom, preferably at rounded corners, extending approximately at right angles to the lateral flanks, but in a preferred embodiment the bottom is inclined so that it is so with one flank enclosing a point intermediate angle and with the other an obtuse intermediate angle. As a result, approximately trapezoidal products can be pressed better in cross section.
    With regard to the pressing method, this object is achieved by the following method steps: a) introducing the product in the longitudinal direction in the open loading end face of the mold, b) moving the stop plate in the transverse direction close to the loading end face of the mold in the closed position, in which it closes the free cross-section of the pressing space on the face side, c) moving the transverse press die forward in the pressing mold in the direction of the bottom of the pressing space up to a fixed minimum transverse distance, d) maintaining the transverse pressing punch for a predetermined holding time, e) f) driving the longitudinal ram forward in the longitudinal direction from the press end face in the direction of the loading end face of the mold while pressing the product, g) moving the stop plate into Transverse direction into the open position, h) pushing out of the pressed product to a pressure from the loading end face by further forward driving of the longitudinal press ram.
    This results in a procedure with very low reloading times and thus a high efficiency.
    This can be further increased by prior to step g), ie before the method of the stop plate in the open position, the longitudinal press die a small distance from its press position is moved back to take the pressure of the stop plate, so that the required for the displacement of the stop plate drive power can be kept low.
    The longitudinal ram is driven forward during longitudinal pressing either up to a predetermined longitudinal position, which is possible only with very uniform products.
    In general, therefore, the longitudinal press die is driven forward during longitudinal compression until a predetermined force or a predetermined pressure on the product is achieved. In this press position it remains - regardless of whether the longitudinal ram is position-controlled or force-controlled - in position for a certain holding time, which is determined depending on the product to be pressed, since some product types require a relatively long holding time to the recovery after removal the press force not or only very hesitant to use.
    If the pressed press produced from the product is pushed out of the loading end face of the press room, the discharge conveyor is put into operation in good time or a combined feed / discharge conveyor in Abförder-direction in operation, whereby the energy consumption a constantly running conveyor is avoided.
    If in front of the loading end face of the press room adjustable in height, so up or down leading, chute - which may be a switching conveyor belt - is present - this is optional when loading with the free end up and swung down during unloading with its free end.
    In a further improved embodiment, the product to be pressed prior to insertion, ie before step a), measured in terms of its maximum cross-section transverse to the longitudinal direction of the generally elongated product, and at a previously retracted position of the transverse press ram to a large cross-section of the transverse press dies against its normal loading position even further back, but preferably still remains at least partially in the first transverse direction within the mold. c) Exemplary Embodiments Embodiments according to the invention are described in more detail below by way of example. Show it:

    Fig. 4: viewed longitudinally a second cross-sectional shape of the mold, by means of the press, a product P, as shown in the figures, pressed, wherein the mold 2 is an upwardly open, extending in the longitudinal direction 10 groove with a U-shaped inner cross section, the channel-shaped recess 9, which does not change over the course direction, ie in the longitudinal direction 10.
    In the upwardly open interior of the mold 2 protrudes - as can be seen in FIGS. 2a to e, about the same length - transverse press ram 3, which is formed strip-shaped, and considered in the longitudinal direction of the 1a for, b has a width which fits exactly in the inner free space of the U-profile, so the trough-shaped mold 2, in and can be moved up and down in this, whereby the free cross section of this pressing space 21 can be changed in this first transverse direction 11.1.
    In Fig. 1a, the transverse press ram 3 is shown in its raised loading position, in which it is with its lower end just inside the U-shaped recess 9 in the mold 2.
    In Fig. 1a, b it can be seen that the bottom 21a of the pressing space 21 facing bottom, the pressing side 3a, the cross-press ram 3 in its cross section at the longitudinal outer edges each have an approximately triangular projection with a concave rounding and also the inner corners of the cross section of the mold 2 are rounded, whereby the pressing space 21 in this first cross-sectional shape of a rectangular cross-sectional shape with rounded
    Has corners, but the cross-sectional shape of the pressing space 21 may also be shaped differently, special rhombic, trapezoidal or pear-shaped.
    The length of the press in the longitudinal direction 10 is reduced according to the invention: The piston rod 4a carries at its front end the longitudinal press die 4, which, according to FIGS. 2a-e, extends from the right-open end face, the press head. Side pushed forth already in the baling chamber 21 is - and never leaves this - but by means of the piston rod 4a in the direction of the left end, the loading end of the mold 2 can be advanced.
    A longitudinal drive 14, be it the threaded spindle shown here or another drive, is located below the mold 2, wherein the movable end of the longitudinal drive, for example a threaded spindle 14, via a transverse connector 22 with the rear end of the piston rod 4a of the longitudinal Pressing punch 4 is connected, while the other end of the threaded spindle 14 is fixedly connected to the base frame 1.
    The cross-connector 22 could be performed for improved stabilization in turn along extending in the longitudinal direction 10 guides and thereby be designed in this side view in particular L-shaped, in which case one leg extends in the longitudinal direction 10, the other in the transverse direction for connection the piston rod 4a of the longitudinal press die 4th
    In this way, the length required in the longitudinal direction 10 for the press is hardly more than twice the length of the mold 2, in particular not more than an additional 20%, better still no more than an additional 10%, twice the length of the mold second
    For downward pressing of the transverse press ram against the product P, so that its cross-section as completely as possible adapts to the inner cross section of the pressing space 21, in particular in addition, the transverse press ram 3 is not as usual from one pointing upwards Reverse 3b from protruding drive such as a threaded spindle is applied, but instead is on the back 3b of the transverse punch 3, a yoke 6, which extends in the visible in Fig. 1a, b the second transverse direction 11.2 to the longitudinal direction 10, while the first transverse direction 11.1 is the direction of movement of the transverse press ram 3.
    The yoke 6 has a length such that it protrudes laterally beyond the outer edge of the mold 2 and there is fixed to each of the upper ends on a variable in height, fixed to the base frame 1 vertical strut, whereby the yoke 6 to a portal is completed.
    The variable length vertical struts consist in this case each of a threaded sleeve 19 ', which are attached to the underside of the yoke 6 left and right of the mold 2 and a rotatable therein threaded rod 19th
    The threaded rod 19 carries in each case in the lower region a rotatably connected to the threaded rod 19 pinion 18, wherein the pinion 18 of the two in Fig. 1a, b left and right of the mold 2 downwardly extending threaded rods 19 of a common gear 16 are driven, which is preferably in a plane which is parallel to the bottom 21a of the pressing space 21, about a running in the first transverse direction 11.1 axis of rotation 16 'is rotatable. As a result, the two pinions 18, in particular the pinion 18 all threaded rods 19 of the press, synchronously driven. This central gear 16 is controlled by a motor M in rotation, by means of a controller 20, whereby a transverse drive 13 is realized.
    As shown in the side view of FIG. 2, are located in the longitudinal direction spaced above the transverse punch 3 in this case to each other two yokes 6 on the upper side of the transverse punch 3, both with lateral vertical trusses to a portal. 6 are completed, where just above the base frame 1 shown here as a plate, the pinion and the central gear can be seen, in which case the central gear can drive all four pinions belonging to the two portals at once.
    Since now only the comparatively flat traverse 6 of the portal is located above the cross-press ram 3, the height of the press does not go up significantly over the top of the press room 2 and / or cross press die 3-depending on the functional position - out.
    Since the longitudinal press die 4 keeps the press end 2b of the pressing space 21 in the mold 2 constantly closed, the pressing space 21 between the transverse press die 3 and mold 2 only from the other, the charging end face 2a accessible, ie from the drawer Finish, load and unload.
    On this loading end face 2a, the free cross section of the pressing space 21 can be completely closed or completely released by a stop plate 5, which for this purpose preferably in one of the transverse directions to the longitudinal direction 10 movable or pivotable about a parallel to the longitudinal direction 10 pivot axis is.
    For loading and unloading as shown in FIGS. 2a-e in different functional positions can be shown one above the other a feed conveyor 8a and a discharge conveyor 8b be present, of which the former above and below the height level of the bottom 21a of the recess 21 in the mold. 2 is located and both in front of the distance
    Press mold 2 end.
    This gap present in the longitudinal direction is bridged by a pivoting conveyor 12 or a swivel chute 12, which is pivotably mounted on or just below the loading-side end of the bottom 21a of the channel-shaped recess 21 in the mold 2 about a pivot axis 12 'extending in the horizontal transverse direction. such that the loading-side end of the upper side of the pivoting conveyor 12 is approximately at the height of the bottom 21a of the recess 21.
    The pivoting conveyor 12 has a length such that it ends after appropriate pivoting its end remote from the press 2 just before one of the two conveyors 8a, b.
    In the swung-up position, a product P to be pressed on the upper feed conveyor 8a can be dropped from the feed conveyor 8a onto the raised pivoting conveyor 12 and, as shown in FIG. 2a, the product P is moved along the pivoting conveyor 12 or Swing chute 12 transported into the interior of the press room 21 into it - as shown in Fig. 2b - or is pushed by appropriate tools.
    In this case, the transverse extrusion die 3 is in a loading position raised so far that the new product P can enter the die 2. In this case, as a rule, the operator, knowing the size of the products to be processed, can preselect one of several loading positions manually before the control.
    In the loading position, the transverse compression ram 3 with its lowermost part is preferably still just in the recess 21, but for this purpose could also have fallen completely out of the recess 21, so that the pressing space 21 has a maximum large cross-section. The longitudinal press ram 4 is located in the maximum far to the right retracted position, in which he is preferably still just partially in the interior of the mold 2.
    As soon as this has taken place, according to FIG. 2c, the stop plate 5 moves into the closed position - in this case moved by means of its own working cylinder - and thereby closes the loading end 2a of the pressing space 21, so that the longitudinal pressing die 4 - after taking the pressing position of the transverse press ram 3 - the product P located in the press room 21 is pressed against the stop plate 5 in the longitudinal direction 10 and this press position shown in FIG. 2d is held over the predetermined holding time.
    Thereafter, the longitudinal press die 4 is slightly withdrawn to relieve the product P the stopper plate 5, and also the transverse press die 3 raised slightly, so after releasing the loading side end of the press room 21 by the stop plate 5 in the Open position has moved, the longitudinal press ram 4, the product P push out of the press room 21 and can push out on the tilted down into the discharge position pivoting conveyor 12 - as shown in Fig. 2e -, from which now to a pressure P ' Pressed product reaches the discharge conveyor 8b and can be transported away from this.
    In Fig. 3a, b, a solution is shown, in which the switching conveyor 12 consists of two superimposed switching conveyors 12a, b, which are preferably firmly interconnected in their mutual distance, and together about a pivot axis 12'verschwenkbar , which also runs in the second transverse direction 11.2, but is located at the opposite end of the switching conveyor 12, in this case coincident with the axis of the local Umlenkritzels for the lower switching conveyor 12b, which indeed has the form of an endless circulating conveyor belt.
    Around this pivot axis 12 ', the entire switching conveyor 12 can be pivoted so that either the top of the upper 12a or the top of the lower 12b switching conveyor with the bottom 21 a of the press room 21 is approximately aligned and ends closely adjacent to this.
    The discharge conveyor 8b is closely adjacent in the longitudinal direction 10 and with its upper side aligned with the upper side, the transport surface, the lower switching conveyor 12b or slightly below. Due to the arrangement of the pivot axis 12 'in the deflecting pinion of this lower switching conveyor 12, b facing away from the shape, this is the case in both switching positions.
    The feed conveyor 8a is disposed above the discharge conveyor 8b at such a height or above and in the longitudinal direction 10 closely adjacent to the top of the upper switching conveyor 12a, when in the downwardly pivoted position, the loading position in which the top of the upper switching conveyor 12a is approximately aligned with the underside 21a of the press room 21.
    As shown in FIGS. 3a, b, this solution will almost always be a switching conveyor 12a, b, because in order to use shell slides in their place, a very large mutual distance between them is necessary and a very large tilt angle between the two switch positions.
    FIG. 4 shows a cross-sectional shape deviating from the previous figures of the press mold 2 and thus also of the press space 21: The bottom 2.3 of the inside contour of the channel-shaped press mold 2 lies obliquely to the two mutually parallel flanks 2. 1 and 2 2.2, and thus takes to the flank 2.1 an obtuse intermediate angle and to the other flank 2.2 an acute intermediate angle, but both are rounded.
    Since the pressing surface 3a of the transverse press ram 3 runs approximately at right angles to the direction of the flanks 2.1 and 2.2, and if it is inclined, then preferably at most as strong as the bottom 2.3, better clearly less, this results in a cross section the pressing space 21, which is approximately pear-shaped or trapezoidal, which allows for corresponding product cross-sections a gentler pressing.
