Present invention is described below in conjunction with accompanying drawing.Figure 1 shows that the equipment of processing shrimp, this equipment comprises a basic framework, briefly with 10 expressions, on this framework, be provided with a movably support, briefly with 11 expressions, framework 10 comprises the side bar 12 of a pair of elongated strip, is installed in relative two ends with the lower beam 13 that side bar 12 joins.This framework also comprises vertical component 14, is equipped with entablature 15 on member 14.

Support 11 has a stand frame, and this stand frame comprises elongated side bar 20, in the end of side bar 20 crossbeam 21 is installed.This support is supported by framework 10, and the setting by a pair of flexible articulated slab or the plate 23 of destroying or force to yield and removable, and this plate 23 of destroying or force to yield is fixed to their bottom on the crossbeam 13 of support and is fixed on the crossbeam 21 of support with their top.Because articulated slab can do flexible motion, so they can be regarded as the part of support, or perhaps the support of support.Elasticity stopper 24 is installed on the crossbeam 15 of basic framework so that its in the motion process of support with articulated slab 23 wherein one contact.Therefore, articulated slab can be considered with other member of support facing to the contact of the block of stopper 24 and has also formed same contacting in operation.

Please continue to consult Fig. 1, can find out further that support comprises the rail bar of 5 pairs of inverted v-shapeds, they are longitudinal extension side by side.25 ' has indicated a pair of special rail bar among Fig. 1.Be spaced apart from each other between rail bar and the rail bar, so that between two rail bars, form an elongated passage.Each all has two to be essentially the smooth surface that faces with each other to rail bar, forms an elongated passage between this two surface.Each also has simultaneously the flat surfaces of two inoperatives to rail bar, and this two surface is opposing each other.Or, also rail bar can be installed like this: make two opposing surfaces of the rail bar of single inverted v-shaped can both be as the side of two adjacent passages.The width of the elongated passageway between rail bar must be noted that between the rail bar to be not completely parallel, so that can be widened in one direction.

The device that is used for traversing carriage 11 and rail bar 25 also is provided on the fixed frame 10, has comprised a motor M on the crossbeam 15 that is installed in framework 10, an end of this motor M and support is adjacent.As Fig. 2 and Fig. 3 clearly show, the output shaft 29 of motor M links to each other with crank axle 30, this crank axle 30 does not overlap with the rotation of motor drive shaft 29, pass a bearing block 31 and supporting thereon away from the end of the crank axle 30 of motor M, the axial line of bearing block 31 overlaps with the axial line of the output shaft 29 of motor M, crank axle 30 itself then passes wall type bearing block 33 and supports thereon, and this bearing block 33 is installed on the crossbeam of support 11.So can see: the running of motor will make the axis rotation of crank axle 30 around the power output shaft 29 of motor, and the rotation of crank axle 30 makes each rotate in a upright plane with articulated slab 23 rail bar 25, and this is because that end of articulated slab 23 bearing rail strips 25 is flexible connection.Because the other end of a pair of rail bar is not driven, only produce swing, so the motion of this end only is shuttle motion but not revolving with an articulated slab.

As shown in Figure 3, motor output shaft 29 is to drive rotation in the direction of the clock, and preferably between 3800 to 4800 rev/mins, the diameter of the circulatory motion track of crank axle is preferably between 30 to 70 mils (mil) for its rotating speed.Or as described above, the two ends of support and rail bar can be driven by motor, and the rail bar of whole length all moves along a rotational trajectory.Select as another kind, motor M also can be installed in two opposite end of rail bar.

Please continue with reference to accompanying drawing, as can be seen, equipment of the present invention comprise that 5 shrimps identical, that will decaptitate are transported to five pairs of rail bars each to last device.These devices are positioned at the platform place of decaptitating of shrimp, a table apparatus wherein briefly indicates with 35 in Fig. 5 and 8, the shrimp feeder 36 that this device and extends all 5 head-removed devices is adjacent, this groove that be installed in support with ends articulated slab 23 next-door neighbours, articulated slab 23 is caught with stopper 24.Each head cutter comprises that one is nipped off cushion block or block 40, and this nips off cushion block or block 40 is installed between a pair of rail bar 25, and this rail bar is adjacent with the top edge of groove 36 to 25.If necessary, this nips off the extension that cushion block can become groove edge.The mechanism of decaptitating also comprises nipping off for one and refers to sheet 41, and this elasticity that refers to that one on sheet band is installed on its end is waved and thrown device (flipper) 44.Refer to that sheet is installed on the flywheel 42, flywheel itself then is installed on the axle 43 loosely, and this axle extends through support, as shown in Figure 1.Axle 43 is supported on the framework 10, and rotatable, and it is driven by a motor, and this motor is not shown in Fig. 1.The axial location of the flywheel 42 of edge axle 43 is kept by the axle collar or the pin of routine.

Flywheel 42 can with driving shaft 43 enter and throw off when operation engagement so that its can be driven with clutch shown in Figure 8.This clutch comprises another flywheel 42 ', and flywheel 42 ' is installed in all the time slightly from the position of flywheel 42, nips off to refer to that 41 of sheets are fixed on the flywheel 42.Clutch action is that the effect by spiral winding produces, and spiral winding briefly indicates with 45 in Fig. 8.Spiral winding changes the position of plunger 46, a friction pulley 47 is installed on plunger 46, and friction pulley is freely rotated in crotch 48.Therefore, through the effect of spiral winding, friction pulley 47 is moved being meshed with two flywheels 42 in its place ahead and 42 ' scalene cone, thereby flywheel 42 has also meshed together with flywheel 42 '.Be equipped with securely on the flywheel 42 and nip off the finger sheet, then also clamped by flywheel 42 ', and drive till spiral winding fails by it.When flywheel 42 meshes with flywheel 42 ', nip off and refer to that sheet 41 is driven till spiral winding fails by the position that is positioned at the below from, on the position below this, nip off refer to sheet can be installed in being separated or keeping in touch an of side on relay 45 shells as rubber cushion.In case this situation takes place, to nip off the finger sheet and will mesh with rubber blanket once more, its direction is down.

The operation of the head cutter of spiral winding 45 control is that the detection by shrimp starts, and shrimp is positioned at and nips off the very approaching position of pad 40 at that time, or with nip off cushion block 40 and in fact also contact.Detect the position of shrimp with the photoelectric detector system of the routine of Figure 10 signal.As can be seen from the figure, the electro-optical system here comprises an infrared light supply 50, this light source 50 be installed in every pair of rail bar 25 an end below, and infrared light detector 51, this detector be installed in groove 36 below.Light source 50 produces light beam 53, and the angle between the direction of this light beam and rail bar 25 bottoms is very little.Also can adopt another kind of system similarly, shown among the figure 50 ': light beam transversal is projected on the rail bar.When a shrimp moves to very when decaptitating platform 35 along rail bar, the continuation of shrimp is moved and will be stopped light beam 53.Shown in Figure 11 A is that this situation begins to have taken place.This detection produces a kind of electronic control circuit, will illustrate as following.This circuit starts spiral winding 45, after an of short duration time-delay, makes to nip off to refer to sheet 41 swings.Second kind of photoelectric sensor system 50 ' can be used as an accessory system of system 50 51 or uses when not wishing to postpone if having time.

Electric control system generally includes a 555IC timer and lags behind and a 7406IC driver with generation time.The output line of detector 51 links to each other with the pedestal of transistor T 1, this transistorized signal collector links to each other with a 5VDC power supply via a resistance R 3, its signal collector also joins with the pin (pin) 2 of timer, the direct ground connection of the pin one of timer, and its pin 5 is through capacitor C1 ground connection, and the pin 4 of timer and 8 joins through another capacitor C2 ground connection and by a resistance R 4 and a power supply., set with a variable resistor R5 with the timer of monostable formal operations, variable resistor R5 is linked to each other with timer with 7 by pin 6 herein, and through an electrolytic capacitor C3 ground connection.

The pin one of 7406 drivers links to each other with the pin 3 of timer with 3.Checking circuit LED59 links to each other with the pin two of timer.When using assisted detector 50 ', its output signal can be directly inputted to the pin one and 3 of driver.The pin 6 of driver links to each other with the pedestal of transistor T 2, and to connect spiral winding 45, spiral winding 45 is connected with a diode 52.The effect of spiral winding makes plunger rod 46 move with joint and nips off finger sheet 41 with axle 43 motions.One group of operating data of this component is as follows:

R1 150Ω

R2 4.7KΩ

R3 4.7KΩ

R4 56KΩ

R5 1M Ω

8 R6 300Ω

R7 4.7KΩ

C1 0.01μF

During equipment operation, when light beam 53 was stopped by a shrimp that shifts near the platform of decaptitating, photodetector 51 was opened and driving transistors T1 work, and thereby made the pin two ground connection of timer.When the pin two ground connection of timer, pin 3 current potentials rise and the pin two and 4 current potentials that order about driver descend, and produce a time-delay by setting variable resistor R5.The electric circuit inspection light beam that sends from diode 59 is activated, and can be used as counter.Pin 4 current potentials descend, and open transistor T 2 thereby drive the rising of pin 6 current potentials, and this makes spiral winding 45 switch on and engages the flywheel 42 of decaptitating.After shrimp decaptitated, the shrimp body fell from rail bar, made light 53 reappear, thereby circuit is disconnected, till follow-up shrimp stops this light beam.

Consult Fig. 6, described as can be seen device can combine with other device, is used for the shrimp of different sizes is decaptitated.Apparatus and method of the present invention also have multiple other purposes.When a pair of rail bar 60 so that mode is driven in rotation as the aforementioned, shrimp placed on it is fed forward on a series of conveyer belt 61 along rail bar, conveyer belt 61 is to move along a circulatory motion track below rail bar.Among this figure, because rail bar extends to when the right from the left side, the spacing between them is widened, so the less shrimp of size will fall on the conveyer belt on the left side, and larger-size shrimp then will be fallen on other conveyer belts; Shrimp is transferred band from here and is transported on the rail bar 25 of combined unit shown in Figure 1, and the width of the vertical passage of this rail bar is slightly different, to hold the different shrimp of size.Therefore each of five pairs of rail bars is to handling the shrimp of a certain size scope, and they can increase the reliability of operation, shrimp can be classified again.

See also Fig. 9 A-9E, from an operation cycle, can very clearly observe out the motion conditions of rail bar.Among each figure here, the left end of rail bar is connected its other end and then is positioned at and the stopper 24 and the platform position adjacent of decaptitating with motor M.Therefore, the left end of rail bar rotates on the figure paper plane, so that this end of rail bar rotates along a circular orbit around an axle that is essentially level at least.This rotatablely moving makes progressively then that the other end is approximate and is linear reciprocal movement, and the other end of this rail bar only is supported on the plate of destroying or force to yield.The position that the position of the rail bar shown in Fig. 9 A-9D can be represented corresponding to Fig. 9 E, wherein four diverse locations in the lower left corner 25 of rail bar are represented with A-D respectively.Like this, Fig. 9 A represents that the lower left corner of rail bar is arranged in the high order end position of front view.

When the crank axle 30 of motor M moves upward (as shown in Figure 3) and arrives the right side, rail bar is raised and moves to the right and towards stopper 25, till when their arrive position shown in Fig. 9 B, its position is represented corresponding to the position B among Fig. 9 E, the further motion of crank axle will make rail bar further move down to the right, contact with stopper 24 up to rail bar, shown in Fig. 9 C, its position is represented with the C of Fig. 9 E.Above-mentioned these all are the situation of rail bar when arriving before the low order end position.From position C, rail bar drops to its lowest point D, shown in Fig. 9 D, and leaves stopper, finally gets back to position A.

As can be seen, shrimp is carried on the rail bar slidably, when this rail bar provides with crank axle, or the suitable speed that provides by a cam or kindred organization and suitable longitudinal translation or length of stroke are when being driven, their the track prawn that rotatablely moves produces a clean momentum, for example promotes the direction operation of shrimp along rail bar.If rotary speed is too low, then shrimp only does elevating movement along with rail bar and not operation forward.Otherwise,, then can cause loss if speed is too high.Iff being vibration, shrimp is moved effectively, because its body structure makes it can absorb vibration.When lateral displacement, when just the track diameter of crank axle was 30 to 70 mils, rotating speed can make device work well between per minute 3800 to 4800 changes.This rotatablely moving of the support of shrimp added its gravity effect, and shrimp is moved along a direction.

Please consult Fig. 9 E again, can see, when rail bar when position A moves to position B, vertical stress component and arrowhead component from left to right all are added on the rail bar, this makes shrimp be raised and shifts to right-hand.To position C, the rail bar support remains and moves right, but also moves down from position B.In fact this make shrimp in right-hand progradation, has only very little shrimp weight to be added on the rail bar, and shrimp and the rail bar below it are in the process of disengagement.Therefore the momentum of shrimp itself makes it with respect to the rail bar bearing support herein, with slide or with fly (airborne)/slide the mode that combines to divide a word with a hyphen at the end of a line to the right.Even rail bar from position C to the moving process of position D, above-mentioned this situation obviously continues because early stage in this part of cycle period at least, the weight that is added to the shrimp itself on the rail bar is very little, and the frictional resistance between shrimp and rail bar is also very little.Therefore, when shrimp is added to its total weight on the rail bar again, rail bar begins another cycle period that makes progress again, to be raised to position A shrimp from position D, therefore, although in the cycle, the vertical stress component and the acceleration of motion are cancelled out each other in whole circulation,, the gravity of shrimp itself make shrimp that the one clean displacement to right be arranged but adding rotatablely moving of rail bar.

Rail bar produces a unexpected blocked force with contacting of stopper when the 9C of position, this power and the aforesaid synergy that rotatablely moves will make rail bar slow down suddenly herein.Rail bar moves right and is considered as its positive-stroke among Fig. 9, and it then is considered as backward stroke to left movement, and when the ending of positive-stroke, the decelerating effect of the decelerating effect that rail bar causes with contacting of stopper during than the ending of backward stroke is stronger.The effect of pushing ahead when this effect can be strengthened shrimp and is supported on the rail bar in the rotation.Therefore, the setting of stopper can obtain a good propelling speed under lower rotating speed.This carrying method of described shrimp is worked with the rail bar combination, and rail bar generally is in the same plane for the throughput direction of shrimp, but also can be downward-sloping direction, even also can be sizable angle that is inclined upwardly.

When shrimp being placed into an end of rail bar, during beginning, they are rambling.But very fast they be rendered as roughly upright state and be bearing in elongated passageway bottom between rail bar with their afterbody.When passage was widened, shrimp was in slightly that the lowland is embedded on the rail bar, is in the position that preparation is as shown in Figure 4 decaptitated up to them.Preferably, for the shrimp that the shrimp headband that makes after decaptitating is walked minimum, their turned position (almost being) along vertical axis just as shown in the figure be to make its feeler and to nip off cushion block adjacent.Like this, shrimp is not only the form transportation with single single file, and they also must be with a kind of predictable upright orientation transportation so that processing.

When shrimp arrives very when nipping off cushion block, nip off to refer to that sheet begins action, i.e. swing in the above, as shown in Figure 5, it refers to that sheet clamps the junction of shrimp head and shrimp body first.When the shrimp head with nip off cushion block connect real after, nip off and refer to that sheet travels forward just in time by cushion block, promptly between cushion block and the finger sheet closest approach be spaced apart 2 mils.Be cut off and fall at this place's shrimp body.The elasticity that refers to the sheet top is waved and is thrown device 44 and the shrimp head that cuts off is waved to throw in the sky of nipping off the cushion block top enter feeder.

See also Figure 14 and Figure 15.There is shown when decaptitating towards the preceding and movement locus mode of shrimp in transportation backward-facing.Here, shrimp is placed on a pair of conveyer and the bearing rail strip 70, and drives so that shrimp forwards by the direction shown in the arrow 71 with aforesaid mode.Setting by the synchronous gate that periodically rises and falls, make and separate between shrimp and the shrimp and be transferred with parallel form, shrimp towards by the photoelectricity perception, this is by the setting of three photo-detectors 74 shown in Figure 15, carries out in conjunction with not shown light-beam generator.Photo-detector 74 is positioned at the positive downstream position of synchronous gate.When shrimp towards forward the time, promptly the shrimp head is at first mobile, when shrimp when rail bar advances, at first be that its head stops two detectors in top, be that its afterbody stops a following detector subsequently.Otherwise, when shrimp towards backwards the time, promptly the shrimp tail moves forward earlier, stops the detector of bottom earlier, stops the detector on top subsequently.Like this, shrimp arrive whereabouts switch (briefly illustrating among the figure) with 75 promptly can learn before shrimp towards.

The whereabouts switch comprises a bit of rail bar 70 ', and this rail bar is usually located at the remainder of rail bar 70 common, the position of extension.One inter-access piece 76 firmly is installed between the two edges, top of rail bar section 70 '.On inter-access piece 76, fix a lifting arm again, and link to each other with not shown driving mechanism, be used for according to the shrimp of detecting towards coming lifting rail bar section 70 '.If detect shrimp towards forward, perhaps be not detect shrimp at least towards backwards, then rail bar section 70 ' keeps other parts of itself and rail bar to directly and not removing.Otherwise, if know shrimp, then start the whereabouts switch, and make rail bar section 70 ' the temporary transient lifting by not shown controller towards backwards.By this way, make towards shrimp forward and be transported to head cutter 80, the breach that then produces by the lifting of rail bar section 70 ' towards backwards shrimp and dropped and break away from rail bar 70, and drop to following auxiliary rail bar 70 " on; at rail bar 70 " on, shrimp is transported to head cutter 82 in the other direction along 81 directions of the arrow among the figure.Or, auxiliary rail bar 70 " on shrimp also can return simply and return circulating path by one and reappose on rail bar 70 via the door of rail bar 70 upstreams.On shrimp body to a duck conveyor belt that drops from head cutter 80 and 82, the shrimp head then holds in two not shown collecting boxs.

See also Figure 13 A-13F, there is shown another preferred form of shrimp head-removed device, the head that shrimp head-removed device shown here comprises clamping shrimp reliably to nipping off cushion block so that the shrimp body cuts off the device that separates from the shrimp head.This head-removed device is still as the aforementioned between a pair of elongated rail bar 84, but, head-removed device herein itself is fixedly located in the platform position of decaptitating, and after shrimp was placed on the rail bar, shrimp was promoted by a water injector 85 that is contained in its back on rail bar.Nip off the lower end that cushion block 86 firmly is installed in swing arm 87 by what the polyester of super high molecular weight was made for one, this nip off cushion block have hard, the quality of surface smoothing or waxing.Swing arm 87 be articulated in pivot pin 88 and the elongated passageway that between a pair of rail bar 84, forms in make arcuate movement.This motion promotes spiral winding 91 by a pulling spiral winding 90 and one and a spring 92 is controlled.Nipping off cushion block 86 has the shrimp of concave surface 94 in the face of coming from the upstream, and this concave surface 94 ends at a tip or pallet 99.This is nipped off cushion block 86 and also has a pit 95 and a hooked flanges or spade sheet 96 at the lower surface of one end.

Described head-removed device also comprises a clamper 100, and this clamper is installed on the pivot pin 101, is driven by a spiral winding 102.By operation spiral winding 102, this clamper can be swung in the direction of the clock, so that shrimp when advancing to the right, can pass through below it, smoothly then to swing counter clockwise with the clamping shrimp to nipping off the cushion block place.At last, as preceding use described to nip off refer to sheet 104.

Investigate Figure 13 A-13F in turn, can see the operating process of decaptitating clearly.Among Figure 13 A, shrimp S is pushed nip off to cushion block along rail bar 84 by water injector 85, and shrimp is to drop on this rail bar from not shown one slide-plate.Water injector promotes shrimp so that its head H moves closer to or touch the concave surface 94 of nipping off cushion block, shown in Figure 13 B and 13C.Clamper 100 is counterclockwise to rotate so that its bottom sides contacts with the back of shrimp herein.Subsequently, this clamper is further by swing counterclockwise, then clockwise direction swing of swing arm 87, thereby make that nipping off the position of flange 99 under the shrimp mouth on the cushion block is driven and cuts the shrimp head, clamper 100 is then pushed down the back of shrimp head, and all these are shown in Figure 13 D.When the shrimp head has been clamped to when nipping off cushion block, nip off to refer to that sheet 104 begins action, its end is driven along arching trajectory moves, and just in time from clamper and nip off the cushion block bottom below by, shown in Figure 13 E.The result who does like this makes it that shrimp H is located to cut off at the chest of shrimp body portion T topmost.At this moment shrimp neck and shrimp foreleg are by flange 99 clampings, and hooked flanges or spade sheet 96 that the shrimp head is positioned under shrimp neck and the shrimp foreleg are stayed in the pit 95 of bottom.Therefore, when nipping off when referring to that sheet swings to position shown in Figure 13 F, it cuts off the shrimp head at its chest uppermost position in fig-ure place, be connected together and stay shrimp neck and shrimp foreleg and shrimp head.Then, clamper and nip off cushion block with a relative velocity all clockwise direction rotate so that the shrimp head is thrown off from the state of clamping.Water injector pushes away rail bar 84 with a shrimp H and enters in the not shown collecting box then, and shrimp body portion T then is collected in another not shown collecting box.

Figure 16 shows the clamper of another kind of form.Herein, briefly with 105 expressions, this clamper has a main body 106 to clamper, and it plays a guide plate, and is installed on the pivot pin 107.Make main body 106 and spiral winding 108 couplings with a pivoted arm 109, main body 106 is rotated around pivot pin 107, inserted link 110 all extends through the passage in main body and guide plate 106 central authorities, arrives another spiral winding 111.Compression spring 112 is limited between the top and inserted link flange 113 of main body 106, makes this inserted link remain on normal upwards position, and to stretch out bottom part body too far away so that its bottom is unlikely.Among Figure 16, demonstrate this inserted link in the situation that is subjected to still to stretch out under the drawing of spiral winding this bottom part body.

Clamper shown in Figure 16 between a pair of rail bar 115, (for make explanation clear for the purpose of, removed a near rail bar from the observer), and be in one slide-plate 116 bottoms, just in time be positioned at the upstream of nipping off cushion block 118 of the bottom that is installed in swing arm 119.During operation, inserted link is risen, allows shrimp to be slipped to slide plate 116, when it moves on a pair of rail bar 115, make its clamp body 106 below by.This inserted link is descended, and main body and inserted link are counterclockwise swung, thereby clamping the shrimp head to nipping off cushion block 118 places.As foregoing, finish the work of decaptitating then.With with preceding described similar electric wiring control operation process.

At last, Figure 17 has described another shrimp system of processing that may adopt when enforcement is of the present invention.In this system, whereabouts switch 120 is inserted in a pair of transportation rail bar 121, and two chutes or slide plate 122 are suspended on this on the rail bar, and this two chute all ends in a pair of fixed bearing rail bar 125.Shrimp towards detecting by a foregoing photodetector 126.Be provided with two water spouts 126 at adjacent position, rail bar 125 bottoms " so that two slide plates can alternately be handled by valve V.Nip off cushion block 127 and clamper 128 and be positioned at bottom position adjacent with slide plate 123, another is nipped off block 130 and clamper 131 and then is positioned at bottom position adjacent with slide plate 122.Not shown nipping off refers to that sheet is nipped off cushion block with each and clamper cooperates.In this system, decaptitate nipping off cushion block 127 places towards the shrimp of a direction, then be transported to towards rightabout shrimp and nip off cushion block 130 places and decaptitate by rail bar 126.

This shows, the invention provides a kind of from failing in commercial very successful use, a kind of method and apparatus of processing shrimp on automation foundation.It will of course be appreciated that the above embodiments only are in order to set forth principle of the present invention in a preferred manner.In the scope that does not break away from flesh and blood of the present invention, can carry out many modifications to the present invention, add or delete some content.
