    Tenderizer with support control
    The present invention applies to a tenderizer for softening at least one piece of meat, comprising a base for direct or indirect support of the piece of meat and support of the tenderizer on a receiving surface, two vertical columns fixed on the base and guiding vertically in use and slidably, alternatively under the action of a manual lever or a motorized connecting rod, a block of knife blocks whose tenderizing knives pass through guide slots forming one or more block (s) of slits carried by a frame and likely to bear on the piece of meat and which are suspended, via the frame, two columns that slide through said frame and are likely to come in support of reaction upwards in use on a first locking cross member may hang in support on the vertical columns under the effect of the reaction force to the crushing of the piece of meat to immobilize in position relative to the columns the frame of the block (s) of slots and let advance the tenderizing knives in the piece of meat, the first crossbar being released relative to the columns by at least one release stop when the frame of the knife blocks moves away from the piece of meat beyond the active position or exit of the tenderizing knives.
    Such tenderizers have proven to work well to cut on a multitude of locations the nerve and muscle fibers of large pieces of relatively hard meat. The pieces of tender meat becoming ever larger, we replaced the manual operation always well dosed because taking into account the reactions of the piece of meat, a mechanical actuation by an electric geared motor actuating a connecting rod that replaces the manual operating lever . This has sometimes resulted in an exaggerated crushing of the piece of meat under the pressure of the block or blocks of knife guide slots. This exaggerated crushing affects in particular the presentation of the meat pieces after tenderness. The present invention aims in particular to reduce, in an adjustable manner and well dosed, the exaggerated crushing of tenderized meat pieces, crushing which is sometimes manifested on certain pieces of meat without it being possible to avoid it by a particular control of the triggering of the tenderizing operation.
    For this purpose, according to the invention, the columns are fixed to a second cross member which is mechanically connected to unidirectional electric blocking actuating means on the columns in the direction of movement towards the piece of meat, said actuating means electrical being triggered by photoelectric detection means of the approach of the contact or of the slit block (s) with the piece of meat, the light-emitting or photoradiative ray-receiving part of the photoelectric means being carried by the frame of the slit block (s), so as to trigger the unidirectional blocking of the second crossbar on the columns before the mechanical release of the locking of the first cross on. the columns under the effect of the reaction of the piece of meat and thereby reduce the pressure exerted on the piece of meat by the block or blocks of slits before penetration of tenderizing knives into the piece of meat, the blocking of the columns on the columns during the removal of tenderizing knives of the piece of meat which is no longer provided by said unidirectional blocking of the second cross member, then being effected by the support of the columns on the first cross member blocking then blocked, until the release of the first cross by the release stop.
    The position of the light or radiative ray of the photoelectric means may be adjustable over a short stroke relative to the frame of the slit block (s) by means of adjustment means acting on the transmitter and / or the beam receiver. light or radiative, so as to allow to vary the distance and / or the orientation of said light or radiative ray with respect to the said slit block (s) so as to vary the distance for triggering the locking of the last crossbar relative to the piece of meat and consequently the pressure of the block (s) of slots on the piece of meat.
    According to another embodiment of the invention, the light ray or radiative ray is oriented substantially parallel to the contact surfaces of the block (s) of slots with the piece of meat and at a short distance from these surfaces, so that the triggering of said blocking electrical actuating means of the second cross member occurs before effective contact of the contact surfaces of the slit block (s) with the piece of meat and thus compensates for the mechanical delay of said blocking with respect to said triggering.
    According to yet another embodiment of the invention, the contact surface of the slit block (s) capable of coming into contact with the piece of meat is set back from an outer rim of the frame of the block (s) of slots surrounding the blocks of slots and carrying the transceiver portion of the photoelectric detection means, said flange being able to constitute an abutment against a lateral sliding of the piece of meat and to delimit, in cooperation with said transceiver part, an approach area where the piece of meat is considered to be approaching said contact surface.
    According to another practical embodiment of the invention, the locking means of the second cross member are mounted at each of the two ends of this second cross member in the vicinity of a respective vertical column in use and comprise a wedge lever traversed by the column and articulated at one of its ends on the cross member and at the other end on the core rod of an electromagnet or electric jack carried by the second cross member and capable, when excited or powered by an electric current controlled by the photoelectric means, to pivot upwards, in use, the jamming lever, obliquely and in the jamming position on the vertical column, an upward thrust in service on the second crossbar in the absence of the action of the electromagnet being able to cause the mechanical release of this jamming lever.
    In the operating position, the second crossbar is disposed above and substantially parallel to the first crosspiece which comprises, at each of its ends, a wedging lever through the respective vertical column and articulated at one of its ends on the first crosspiece through which the columns each comprise a support plate adapted to come to rest on the first cross in reaction upwards when the columns are no longer retained by the second cross, especially when the electromagnets or the electric cylinders are no longer excited after the rise of tenderizing knives out of the meat piece, and the frame of the knife blocks comprises, opposite each jamming lever of the first crossbar, an unlocking stop, preferably adjustable, suitable to come to bear on said jamming lever to unlock it when, under the action of the return to service of the frame With knife blocks, the knives are tucked into their guide slots. Each of the columns comprises a connection head to the second crossmember and to the support and connection plate, this head being adjustably connected by screwing to the lower part in use of the column and being able to be immobilized in rotation after adjustment. by a locking screw in rotation of said plate, screwed into the second cross-member through the first and second cross members and coming to anchor and bear in a recess or notch of said support plate.
    According to another embodiment of the invention, the two vertical columns carry a plate that supports an actuating mechanism by its manual lever or by the motorized connecting rod and various electrical organs, the plate being also resting on the support base by means of hollow front columns able to serve as passages and protection of the connecting son between members placed on the plate and the region of the base and the hollow front columns form with the vertical columns axial guidance for a receiving board of the piece of meat and placed on the base. The electrical members mounted on the support plate preferably comprise an electrical connection, removable but permanent in use, two-hand safety switches mounted on the receiving board of the piece of meat.
    Other objects, advantages and features will appear on reading the description of various embodiments of the invention, given in a non-limiting manner and with reference to the appended drawing, in which: - Figure 1 represents, in perspective from above and partially schematically, a tenderizer or tenderizer a piece of meat according to the invention; FIG. 2 shows, on a larger scale, in fragmentary view and in schematic section, the slit blocks of the knives of the tenderizer about to come into contact with a piece of meat under the control of photoelectric detection means. the approach of the piece of meat; - Figure 3 shows, in fragmentary view and in section through the axes of a column and a neighboring column, the area of the sleepers and their position adjustment; - Figure 4 shows, in fragmentary view and in section through the axis of a column, the electrically actuated locking means of the second cross member on a vertical column.
    The machine according to the invention for the tenderizing of at least one piece of meat, a machine which will be called thereafter under the term "tenderizer" is mounted, like any machine in general, on a base 1 intended to be placed on a receiving surface, for example a work table 2. This base 1 also serves to support, directly or indirectly, for example by means of a support board 4 of wood or plastic, the or the piece (s) of meat 3 which will be tenderized by a tenderizing action of the tenderizer. The base 1 carries two rigid vertical columns 5, 6, usually solid tempered steel and chrome or stainless steel and fixed rigidly on the base. The vertical columns 5, 6 guide alternatively sliding upwards and downwards by the manual or motorized actuation of a connecting rod 7, a frame 8 for receiving knife blocks 10 and connecting to the operating rod. 7.
    The multiblade knife blocks 10 are each included in an overmolded bar 10 '(dashed in FIG. 1) spaced apart at the assembly and are placed on two lateral support bars by lateral extensions of their upper spacers 10 'made of plastic.
    The assembly of the knife blocks 10 is held laterally by a retaining plate 9 integral with the frame 8. The blades 10 "of the tenderizer knife blocks are shown laterally in FIG. 2 or are well separated and in a thickness reduced to better reveal the guide slots 11 in which they are engaged.The guide slots 11 are formed in blocks 12 of slots generally made of hard plastic material but which can also be replaced by a single metal block foundry. The vertical columns 5, 6 carry at their apex a plate 13 supporting in particular an electric gear motor actuating the connecting rod 7 which comprises means 15 for adjusting the range of the knives 10 "of the knife blocks 10 relative to the board 4 on which is placed the piece of meat 3 to tenderize. For the manually operated tenderizers, the geared motor unit 14 is replaced by an actuating linkage also mounted on the plate 13 and mechanically connected to an actuating handle (not shown).
    The blocks 12 of slits 11 are carried by a frame 16 suspended on columns 17 and 18 which pass through circular passages, the solid frame 8 and, above the frame 8, a first cross member 19 for locking the frame 16 on the vertical columns 5, 6. The first crosspiece 19 comprises, on each side located near a column 5 or 6, a mechanical locking lever 20 on the column 5 or 6 which it surrounds in the manner of a ring . Referring to the fragmentary sectional view of Figure 3 showing a portion of the column 18, it is seen that each post 17, 18 is terminated by an adjusting head 21 with hexagonal adjustment. The adjustment head 21 is connected by an assembly screwed to the column 18 and to a support plate 22 on which the first crosspiece 19 is able to come to bear, in particular when the frame 16 is pushed upwards by the reaction of the piece of meat 3 on the blocks 12 of slots 11. As shown in Figure 3, an upward push on the first cross member 19 causes, under the effect of gravity and friction, the pivoting of the levers 20 when the frame 8 of the knife blocks 10 rises under the action of the rod 7 (for example after penetration of the knives 10 "of the knife blocks 10 in the piece of meat 3 for a tenderizing operation), to extract the knives from the piece of meat, at the moment when the knives 10 "having left the contact with the piece of meat are erased in the slots 11, an unlocking stop 23, settable e in height by a system of screw and lock nut 24 and thus carried by the frame 8, pushes up the wedging lever 20 and unlock it, thus freeing the locking of the first cross member 19 on the columns 5, 6, which allows the raising of the columns 17, 18 causing the frame 16 of the bloes 12 of slots, hanging on the columns.
    According to the invention applied to tenderizers of meat pieces, the posts 17, 18 are fixed to a second cross member 25 here rigidly connected to the posts 17, 18 by a thread of the heads 21 of the posts. The second crossmember 25 is mechanically connected, on each side in the manner of the first crossmember 20, to wedging levers 26 surrounding the respective columns 5, 6. Each of the wedging levers 20, 26 is pivotally articulated by pins 27. and 28 to the first crossmember 19 and respectively to the second crossmember 25. The wedging levers 26 of the second crossmember 25 are each mechanically connected by a pivot joint 29 and a core connecting rod 30 to the core of an electromagnet 31 which pulls towards the top of the figure when it is electrically excited. Of course, in case of need for a greater traction effect, the electromagnet 31 may be replaced by an electric jack or other and the rod 30 by a cable. The electromagnets 31 are fixed on a sheet back 32 secured to the second cross member 25 to move thereby with it.
    As seen in Figure 2, the frame 16 which carries the blocks 12 of slits 11 and which is suspended from the columns 17 and 18, comprises a flange 33 fixed by any suitable means such as screws 34 shown schematically. This flange 33, which extends well beyond the generally planar bearing surface of the blocks 12 of slots, carries a transmitting and receiving photocell 36, 37 for example with an LED diode and which can be replaced by a set equivalent to a light or radiative ray. intended to be intercepted by the piece of meat 3. The photocells 36 and 37 are mounted on the rim 33 by adjustable supports 39 and 40 which make it possible to arrange the light beam 38 substantially parallel to the bearing surface 35 but also in forming a small angle with this surface, the important thing being only that the ray emitted by the transmitter 36 is well received by the receiver 37, outside the interception of the ray by an obstacle such as the piece of meat 3.
    The cells 36 and 37 are electrically connected to a power supply and control unit 41 which is carried by the plate 13. The block 41 is connected, in use, to the power supply network, buttons and / or switches control units arranged on a case of the tenderizer or, as shown in Figure 1, to one or more switches arranged on the board 4 and removably connected to the base 1. The electrical block 41 provides power to the geared motor 14 and electromagnets 31 when the light or radiadic ray 38 is intercepted, for example by a piece of meat 3. The rim 33 may in certain cases form a stop to laterally retain the piece of meat 3 and, because it carries the transceiver of light ray, it delimits by its height of projection the approach zone of the meat piece by the bearing surface 35.
    The plate 13 is carried not only by the top of the columns 5, 6 but also by the front columns 42, shown fragmentarily in Figure 1 and fixed on the base 1. These front columns are preferably hollow and perform two functions additional. They then serve as passage and protection for the connection wires between the members placed on the plate 13 and the switches in the area of the base 1. On the other hand, as seen in FIG. 1, the front columns 42 cooperate. with the rigid vertical columns 5, 6 to provide axial guidance on the base 1 of the board 4 for receiving the piece of meat 3.
    The locking levers 20 and 26 respectively mounted on the first and second cross members 19, 25 are known per se. They consist of a ring inside which is machined or formed a circular edge 42 having an inside diameter slightly greater than the outside diameter of the columns 5, 6 on which are mounted the rings of the levers 20, 26. As soon as the The rings of the levers 20, 26 are arranged obliquely, the inner circular edge 42 frictionally clings to the outer surface of the columns in the direction of movement of the first and / or the second cross member, confirming the biasing of the jamming lever by the respective joint 27 or 28. A unidirectional blocking of the wedging levers 20, 26 is thus achieved on the respective columns 5, 6. The same effect is obtained on the levers by the action of the electromagnets 31 pulling on the connecting rod 30.
    The position of the lower part of the columns 17 and 18 which holds the frame 16 by embedded heads 21 '(see FIG. 2) which can be integral with this frame, is adjustable relative to the heads 21 fixed on the second crossbar 25, by exerting a rotation action on the six feet of the heads 21, easily accessible. To avoid inadvertent adjustment under the effect of vibrations, the support plate 22 is immobilized in rotation by the tip pin 43 of a locking screw 44 with hexagon socket screwed into a threaded bore of the second cross member 25. The screw 44 and the rod 43 pass through the first and second crosspieces 19, 25 and the tip of the rod 43 is housed resting in a recess or notch 45 of the plate 22, so as to take off slightly one the other the first and second crosspieces 19, 25. The axial adjustment of the columns 17, 18 is performed by screwing more or less deep, in the threaded bore 46 of a column 17 and 18, a threaded rod 47 integral with the plate22. As briefly shown in FIG. 3, to facilitate the sliding of the frame 8 on the columns 5, 6 and on the posts 17, 18, sleeves with a low coefficient of friction 48 and 49 are mounted in the frame 8, respectively around the columns. 5, 6 and columns 17, 18.
    We will first explain the operation of the tenderizer according to the invention in the absence of operation of the photoelectric means 36, 37. When we have on the board 4 a piece of meat 3 to tenderize and that an operator operates the start buttons 50 bi-manual security, the tenderizing operation begins. The start buttons 50 are permanently connected but removable to a connector 51 (only one is shown) on the base 1 and from there to the electric block 41, the two switches 50 of two-hand security requiring the operator to hold to both hands board 4 at the moment of the tenderizing operation. As indicated above, it is first assumed that the electro-airnants do not work after the operator has actuated the two start buttons 50 of the two-hand security, the rod 7 actuated by the electric geared motor 14 pushes the chassis 8 to which it is articulated in 52, downwards. It is noted that a connecting rod passage 53 is arranged through the first and second cross members and allows the free oscillation of the motorized connecting rod 7 during its actuation by the geared motor 14.
    The frame 8 pushed down by the rod 7 slides on the columns 5 and 6 by being pressed on the bars 10 '(not shown) of the knife blocks 10. By releasing the contact of the stops 23 with the wedging levers 20, the frame 8 descends with the columns 17 and 18 because the jamming levers 26 of the second crossbar 25 are unlocked by gravity with respect to their jamming on the columns 5, 6, until contact with the bearing surface 35 of the blocks 12 of the slots 11 with the top of the piece of meat 3. The force of reaction to the crushing of the piece of meat 3 is capable at a certain point of crushing the piece of meat 3 to oppose to the action of gravity on the frame 16 (including the flange 33, the blocks 12 of slots 11, the columns 17, 18 and the first and second cross members 19, 25), increased action of the friction of the columns 17, 18 on their guide sleeves 49 integral with the frame 8. The posts 17, 18 s have then pushed up by the reaction force of the meat piece 3 and act by the plates 22 on the first crosspiece 19 which places the wedging levers 20 in the position shown in Figure 3 where they are locked on the columns 5, 6 as long as a force is exerted upwards by the plates 22. The frame 16 is then immobilized and the knives 10 "of the knife blocks 10 pass through the slots 11 of the blocks 12 of slots and enter the room 3 substantially to the immediate vicinity of the surface of the board 4, thanks to the adjustment of the length of the connecting rod. Then the rod 7 causes the raising of the frame 8 which is pulled upwards by the lateral support bars of the bars 10 'blo-knives 10, so that the knives 10 "are removed from the piece of meat 3 and fade in the slots 11 until the abutments 23 come to bear on the wedging levers 20 to release the first crossbar 19. The columns 17 and 18 driven upwards by the friction of their guide sleeves 49 integral with the frame 8 can then push upward the first crosspiece 19 by the trays 22 and the second crosspiece 25 bearing on the first crosspiece 19 and optionally on the trays 22 by the tip rods 43.
    It is understood that the piece of meat 3 supports, before the penetration of the knives 10 "sliding in the slots 11, the total weight acting on the frame 16 and enumerated above, this weight being increased by the friction of the downward movement of the guide sleeves 49 integral with the frame 8, relative to the columns 17 and 18. This friction may be low but it often becomes important during the use of the tenderizer, for example after penetration of debris in the game between the existing sleeves 49 and the columns 17, 18. The piece of meat 3 subjected to too much pressure from the bearing surfaces 35 of the blocks 12 of slots 11 before the locking of the wedging levers 20 on the columns 5, 6, appears then overly flattened by the non-adjustable pressure exerted by the connecting rod 7 before the raising of the columns 17, 18. The piece of meat 3 and loses some of its commercial value after tenderizing. deny is generally avoided in case of manual operation of block 10 knives because the operator can enjoy its pressure and observe the effect of this pressure on the meat. On the other hand, when actuated by a motorized connecting rod, excessive pressure exerted on the piece of meat is detected only after the appearance of its effects after tenderness.
    We will now explain the operation of the tenderizer according to the invention when all its elements operate (including the photoelectric detector 36, 37, 38 and the electromagnets 31). When the light ray or radiative 38 is intercepted by the piece of meat 3 during the descent of the frame 8 accompanied by the columns 17, 18, as shown in Figure 2, the bearing surface 35 of the blocks 12 of the slots 11 reached a short distance from the upper part of the piece of meat. Interception of the spoke 38 by the piece of meat 3 triggers instantaneously, through the electric block 41, the power supply of the electromagnets 31. The core rod 30 of the electromagnets 31 is then pulled upwards in the position shown in FIG. 4 or the jamming levers 26 of the second crossmember 25 are arranged at an angle to come to a standstill by their inner edge 42 on the columns 5, 6. It is understood that a small delay of some milliseconds, of mechanical origin , flows between the pulling of the connecting rod 30 and the effective locking of the edges 42 of the wedging levers 26 on the columns 5, 6. This delay of mechanical origin can be added to an electromechanical delay of actuating the electromagnets 31 and generally results in supporting, with a low pressure, the bearing surface 35 of the blocks 12 of slots 11 on the piece of meat 3.
    The second crosspiece 25 is then firmly held in position by the locking of the wedging levers 26 on the columns 5, 6 and it retains, by the posts 17, 18 which it is secured by screwing, the frame 16 which no longer crushes excessively, by its bearing surface 35, the piece of meat 3 through which penetrate the knives 10 "which pass through the slots 11 and are pushed by the frame 8 which continues to slide down on the columns 5, 6 under the pushing the motorized rod 7 which pushes the bars 10 'of the knife blocks 10 downwards.
    After having penetrated almost completely through the piece of meat 3 to the vicinity of the board 4, the knives 10 "back up under the action of the motorized rod 7 acting on the frame 8. The displacement of the sleeves 49 integral with the frame 8 relative movement relative to the columns 17, 18 and which was oriented downwards during the penetration of the knives 10 "into the piece of meat 3, reverses upon the ascent of the knives 10" to exit the piece of meat. friction force exerted by the sleeves 49 on the columns 17 and 18 up these columns 17, 18 whose plates 22 are applied to the first cross 19 and bring the first cross in the position shown in Figure 3 or the edges 42 of the wedging levers 20 are locked on the columns 5, 6 by stopping the upward rise of the frame 16 and the bearing surface 35 which is integral therewith. then in general suspended to the set of knifing knife blocks 10 and is detached from the board 4 to remain applied on the bearing surface 35 then immobilized upwards by the support of the plates 22 on the first cross member 19 blocked by the wedging levers 20 on the columns 5, 6. The removal of the knives 10 "of the piece of meat 3 continues under the effect of the raising of the frame 8 pulled by the motorized rod 7, until the moment the friction knives 10 "in the piece of meat 3 is no longer able to hold the piece of meat which, under the action of gravity, is extracted from the last knives 10" engaged and falls on the board 4.
    The rise of the knives 10 "continues until they are fully retracted into the slots 11 of the blocks 12. At this moment, the abutments 23 come to bear on the wedging levers 20 of the first crossmember 19 and unlock these levers with respect to the columns 5, 6. The columns 17, 18 are then supported by the plates 22 directly on the first cross member 19 and indirectly on the second crossmember 25 whose locking levers, even if they are still pulled by the electromagnets 31, mechanically release under the action of an upward thrust.In general, the piece of meat 3 has stopped interrupting the light ray or radiative 35 and the electromagnets 31 are de-energized and no longer exerting traction on the core rod 30. Even if a small tensile force remained on the core rods 30 due to the hysteresis of the electromagnets 31, the force exerted on the plates 22 by the friction of the sleeves 49 would be sufficient to to unlock the jamming levers 26.
    At the end of the upward stroke, the motorized connecting rod 7 is immobilized by stopping the electric geared motor 14 and the entire chassis 8, sleepers 19 and 25, knife blocks 10 and frame 16 are moved with the backrest 32 carrying the electromagnets 31, in the high position close to that shown in Figure 1, ready to receive a piece of meat tenderizer 3 on the board 4 to two-hand security.
    After placing a piece of meat tenderizer 3 on the board 4, the operation of the start buttons 50 bi-manual safety triggers the lowering of the frame 8 of the knife holder 10 and the frame 16 of the blocks 12 slits, to the position shown in Figure 2 or begins to operate the support control system of the tenderizer according to the invention.
    As indicated above, it is possible to use for the implementation of the present invention any suitable light or radiative ray system 38 intended to be intercepted by a piece of meat and which can be adjusted close to the bearing surface 35 by the adjustment means 39, 40. The electromagnets 31 and their connecting rods 30 may be replaced by electric or other cylinders providing interruptible traction on the wedging levers 26, for example by a cable system and sheaths.
    Well understood, the present invention is not limited to the embodiments described and / or represented but it also applies to all embodiments easily accessible to those skilled in the art.
