Description

With the tableted method and apparatus of food bar

Technical field

The present invention relates to a kind ofly, comprise following process steps the tableted method of food bar:

A) food bar transmits on the cutter sweep with a rotating blade;

B) during feeding, cut into slices gradually at front end along direction of feed by the food bar cutter sweep:

C) in order to form portion, section is left on the middle receptacle that can move transverse to direction of feed and along direction of feed after separating from food bar;

In addition, the present invention relates to a kind ofly, comprise the tableted equipment of food bar

A) have the cutter sweep of rotating blade,

B) feed arrangement, food bar can be sent to cutter sweep by it,

C) receptacle in the middle of can be deposited the sheet that downcuts gradually from food bar on it during food bar is sent to, and it can not only move transverse to direction of feed but also along direction of feed,

D) conveying device, a plurality of sections can be transferred on the conveying device from described at least one middle receptacle jointly.

Background technology

For example by the method and apparatus of the described type of the known a kind of preface of US-A-3842698.Yet receptacle in the middle of disclosed equipment has two in Figure 10 to 14 of above-mentioned document, they can carry out the transition to the position of accepting that it is in the food bar below respectively from the other holding fix of food bar cross section in the other direction.In known method, except the middle receptacle that also can support movably along direction of feed perpendicular to direction of feed, be used for accepting respectively complete portion by the section of vertical stacking form up and down, so that with they conveying elements, hand to the conveying device that comprises many circulation belt laces after this by connecting as the centre.Described conveying element is from the downside back to food bar of conveying device, enter in the space between the adjacent belt lace, and invade equally in the middle of the fork-shaped in the space in the receptacle, can arrive in this way formed this a downside and can support reception it.

Using in the middle of two receptacles is can continuous feed for food bar, that is to say, discharge Manufactured this a in, can implement the feeding of food bar incessantly.In the middle of a folded section still is in one on the receptacle or just in time be transmitted the element reception period, receptacle has been in holding fix or has moved to the position of accepting of food bar cross section below in the middle of another, thereby can proceed cutting process incessantly.

This not only brings the advantage of cutting power aspect, because the continuity of cutting process has correspondingly improved cutting power, but also avoids the dangerous in principle interruption of feeding.That is to say, the fluctuation of feed speed, especially food bar is suddenly stopped in short-term, especially for more soft deformable food (for example meat intestines, cut meat pie, beer ham, cheese etc.), based on material so the vibration characteristics that has, thereby in the feeding district, cause going wrong.Because pass nozzle next-door neighbour blade top makes the feeding of food bar be subjected to very big frictional force easily.Cause so-called " dragging-draw (Slip-Stick) effect " thus, that is when surpassing certain centripetal force, cause food bar " outburst " suddenly, that is send to rapidly.Therefore,,,, will cause stretching out in a small amount, consequently downcut some little pieces of food (" fragment effect ") at the blade plane downside in vertical vibrations of food bar blade one side end although attempt stops food bar based on the big dynamic force of all motions.Especially under the situation of packing as the self-service of packaging material with transparent membrane, this fragment becomes makes us unacceptable serious open defect.Therefore guarantee the free of discontinuities continuous feed, be to obtain high cutting power and especially also be to reach the important prerequisite condition that has first-class chipping qualities in the physical dimension of cutting into slices aspect identical all the time.

In by the method for US-A-842698 in order to solve above-mentioned knotty problem, at described structural cost height of the prior art, and the control law systematic comparison complexity that is used to control many part of appliance motion processes.

In addition, by the known a kind of equipment of DE19713813C1, it allows to flow continuous formation one by one by a section of making by cutter sweep and piles up.Opposite with above-mentioned US-A-3842698, here pile up by the single part of middle receptacle formation of piling up adaptor that is called, for the further formation of piling up, that is completeization in order respectively to pile up, it is transferred to a conveying device that is called the band (Portionierband) that is divided into a part.In known equipment, when be divided into a part with on proceed and finish in the described process of piling up formation, piling up adaptor can finish and turn back to a position (holding fix), pile up in order to form next part, it can push the section stream (accepting the position) from this position.

By in the method or equipment of above-mentioned two files, the vertical stacking that can only make section is as finished product part, and well-known, also can make imbricate sheet row by cutting equipment.This covering watt can be made partly overlapping section straight line row, covers watt but also can make circle by the shape of fan.It is contemplated that also that in principle other deposit image arbitrarily, in known equipment, cut apart that back in blocks directly cuts into slices thereon deposit or make part and completeization be divided into a part band, also can move along a direction transverse to direction of feed.If only should make linearity and cover watt row, the simple conveying device of band that then is divided into a part is just enough.If also should realize the more complicated image of depositing, then for example conveyer belt can move along a direction transverse to its throughput direction.

In becoming known for the method that imbricate section deposits, thinking unsatisfactory is that ability to work is lower, because one of beginning is new cover watt part before, the covering watt part and must leave of completeization before below the food bar cross section clashes with follow-up section avoiding.Owing to this reason, the rotating speed of cutter can only be lower.As top explanation already, based on the big dynamic force of this cutting process, pause feeding or make the slack-off all non-feasible approach of rotating speed of blade.

Summary of the invention

Method from the described type of preface the objective of the invention is, and advises a kind ofly with the tableted method and apparatus of food, also can reach other the image of depositing this moment, and to form vertical section folded to replace.

At the technical elements of method,, take following measure to achieve the above object: on middle receptacle, to cause imbricate sheet row by section from the method for the described type of preface.Therefore be associated with temporal advantage by method of the present invention, that is high cutting power is arranged, wherein use a middle receptacle, section temporarily is arranged on the middle receptacle with the attracting imbricate sheet row of outward appearance.In the application's scope, imbricate sheet row are interpreted as the image of depositing that all can imagine, wherein, it is folded that these sections do not constitute a section vertical orientation, that slicing edge is aligned with each other all the time.Therefore cover by the application's meaning and watt be interpreted as that also fan-shaped, flakey is arranged or the tortuous shape of this sliced section is deposited, thereby make on the whole one have air blanketing and thereby capacious section part, this is practical under section situation as thin as cicada's wings especially, so that later easier they are separated from each other.

Preferably adopt single middle receptacle just can satisfy the demand by method of the present invention, and a plurality of sections, that is part part, jointly, that is all sections, more or less simultaneously and directly shift from middle receptacle explicitly, that is not by connecting in the middle of the known independent conveying element of US-A-3846698.Significantly be reduced to the production cost of enforcement thus by the equipment of the inventive method.The present invention not only reduces structural cost, but also aspect the equipment and technology conversion of new method, simplify control, because on the one hand, be reduced between middle receptacle and conveying device and coordinate between middle receptacle and the conveying element and on the other hand complicated coordination between conveying element and conveying device.

An expansion design by the present invention program aspect method and technology is, portion is transferred on the conveying device from middle receptacle under incomplete state, and, this portion that has shifted is during it is placed on the conveying device, by cutting with increase at least another completeization of sheet and finally discharge from equipment.

Therefore divide two stages to make a finished product part, that is a stage, this portion that receptacle is used for forming as supporting mechanism in the middle of (at first) at this moment.After after a while, after that is to say the section of making this a some that was forming at that time, when cutting process carries out continuously, that is especially also do not changing continuous feed and do not changing under the situation of blade rotation, it is transferred on the conveying device, therefore this is safe from danger, because carry out depositing of other sections at this a upside, that is increase, and be bearing in downside by conveying device and carry out from changing to by the supporting of middle receptacle, and thereby can be designed as, this change is not had extremely in disturbing for this a upside that is forming.

Consequently reduced the equipment cost equally,, still can cancel the member that exists there because compare with US-A-3842698 as requirement for controller, that is receptacle in the middle of second.Because in pressing method of the present invention, middle receptacle is in making a process, that is be idle before its completeization, that is to say this portion that no longer needs to be used at that time, so during this a completeization at that time, middle receptacle can be placed in holding fix, so that it was in that this can place down a first the position of accepting after a complete rapidly at that time.

Section can especially easily be shifted from middle receptacle to conveying device, as long as the pallet of receptacle enters in the space between the adjacent belt lace of conveying device in the middle of when described shift, the surface of these sheets of tray supporting is in the lower face that the conveying device belt lace carries these sheets after transfer.By above-mentioned insertion, the change of section supporting from middle receptacle to conveying device takes place.

Another design recommendation of the present invention, middle receptacle is implemented a kind of by moving that the component motion that moves is formed along the geometric locus of a closed in itself, middle in this case receptacle

-from holding fix, this moment, it was in outside the projection of food bar cross section perpendicular to food bar longitudinal axis and comprising in the plane of tray surface at one,

-be arranged essentially parallel to above-mentioned plane motion to the first to accept the position, accept first of new portion this moment,

-then move to the follow-up position of accepting gradually, in these positions it for always cause section expectation deposit image and in order to accept each follow-up section, move along the food bar direction of feed and/or perpendicular to the food bar direction of feed with respect to the position of accepting that arrives before this

-after the section of accepting predetermined quantity, occupy evacuate position, receptacle and conveying device are seen along direction of feed and are moved relative to each other in the middle of this moment, and the surface of these sheets and pallet is disengaged, and generation enter contact condition with conveying device belt lace surface, and

-transfer to holding fix at last again, the plane on conveying device belt lace surface does not contact with pallet in the belt lace zone in this process.

Section is transferred on the conveyer belt from middle receptacle, advantageously reaches in the relative motion process that between middle receptacle and conveying device carries out along direction of feed.In this case, middle receptacle correspondingly sinks when conveying device is static, or conveying device is upwards moved towards food bar along direction of feed when middle receptacle is static.Also can make up above-mentioned two kinds of motion modes, at this moment, based on the frame transfixion, the vertically relative motion of middle receptacle and conveying device.

During cutting operation, when manufacturing simple vertical (non-imbricate) section is folded (this still can realize on by equipment of the present invention), conveying device (or also have in advance in the middle of receptacle) is sink the gradually amount of slice thickness of the section of each new interpolation, so that in whole cutting process, between blade cuts face and the new storage surface that forms the section surface of (in form for middle receptacle surface or this a slice of having downcut recently), reach a constant spacing.Also can implement this sinking when making imbricate by the present invention on middle receptacle, especially this is quite reasonable under the bigger situation of (observing along direction of feed) thickness covering watt.

For receptacle in the middle of moment of first section activation of being used to accept new portion at middle receptacle can " push " apace, meaningfully, middle receptacle is in that a slice of downcutting fully recently its tray surface at its holding fix to face in the surperficial same plane of food bar on conveying device.Therefore when conveying device continues (continuously or progressively) sinking, the next one constantly just in time downcutting and the section of further sinking slightly above, cause so big vertical space, so that middle receptacle can be introduced in the food bar cross section transverse to direction of feed.

For have time enough be used in the middle of receptacle " push " in the food bar cross section, begin under the cutting a slice and be in the food bar cross section when inner at blade, just middle receptacle leaves holding fix.Under the crucial especially situation of time relationship, that is when cutting frequency when high and cutting power is more intense, middle receptacle when it moves in the projection of food bar cross section in a plane vertical with direction of feed, with the surface of its pallet promote the section that forming at that time again in addition under the gravity effect sagging or even be put into before part above cutting into slices.Carry out the transition to by middle receptacle in this way and accept the position, what new this a slice that forms of cancellation had set about carrying out in preceding a section again deposits, so that dispose the section that this new portion was forming at that time, that is deposits in the middle of implementing.In this respect importantly, on the one hand blade and on the other hand in the middle of receptacle, enter in its cross section at the opposition side of food bar.

Be that the measure of taking that achieves the above object is aspect equipment and technology, middle receptacle can move and be, can cause imbricate sheet row on middle receptacle.This is in known equipment, or owing to lack enough areas on middle receptacle, or because the possibility of motion is not provided, so can not realize.Preferably, middle receptacle is from accepting the position, and can accept first of new portion this moment by it, can be gradually away from holding fix in the process that causes the imbricate section to deposit, holding fix it in a plane parallel with cut surface, be in fully outside the projection of food bar cross section.

In this case, with accept the folded necessary motion cycle of terrace cut slice for simple intermittence and compare, still cause the possibility of moving that middle receptacle is expanded along the typical later on discharge direction of complete part by equipment of the present invention, and be under the situation of using conveying device.Yet allow strong especially cutting power by equipment of the present invention, reduce to minimum degree because push stroke (holding fix and accept distance between the position), and middle receptacle further motion gradually later on, carry out along the direction identical, but can have corresponding time delay to take place (corresponding) with the whereabouts of subsequent slice with push-on process.Wherein increase by another kind and to push stroke and cover watt-hour and moved the method that direction reverses again constituting subsequently, under the identical situation of the speed that pushes, middle receptacle is accepted needed disadvantage in time ground, position increase (being equivalent to extended stroke) in order to arrive.

Therefore by equipment of the present invention when finishing to push, in the process of then covering watt, the reverse of the receptacle direction of motion in the middle of not implementing.Just after a part part is transferred to conveying device from middle receptacle, when middle receptacle must be again when the food bar cross section shifts out, just move and turn to, (compare) the stroke lengthening at this moment with a kind of method that reverses of and then taking to move after the position is accepted in arrival unimportant, because also have time enough that middle receptacle is returned holding fix until completeization of this part.

By a design of present device, a plurality of sections can directly be transferred on the conveying device from middle receptacle jointly.The advantage here still is to cancel the sort of independent conveying element as introducing in US3842698.

Be by an expansion design of the present invention, middle receptacle has pallet, tray arrangement is that it can be positioned in the space between the adjacent belt lace of conveying device, and the plane parallel that determine by tray surface this moment is extended in a plane of being determined by conveying device belt lace surface.By above-mentioned these surperficial collimations, cause special love ground to cut into slices and be transferred to belt lace from middle receptacle, obtain to deposit the extra high quality of physical dimension thus.Preferably, middle receptacle is made fork-shaped, and tray design is sharp-tooth shaped and is installed on the crossbeam, preferably welding with it.

Owing to when the motion of middle receptacle, have big dynamic force, so that the quality of the middle receptacle that will quicken strongly should remain is as far as possible little.This is appropriate especially because middle receptacle since imbricate deposit and cause and form simple piling up and compare inevitable much bigger (length and/or width).Owing to this reason, pallet should preferably less than its 1.5 times, especially less than 10mm, preferably less than 8mm, more preferably be between 4mm and the 6mm less than the twice of the sheet thickness that will downcut along the height of direction of feed metering.The quality of middle receptacle should be less than 0.5kg, preferably less than 0.3kg.As receptacle in the middle of being used for, especially the material of pallet except that stainless steel or light metal alloy, also can be considered fibre-reinforced plastics, especially uses carbon fiber.

In configuration aspects advantageously, middle receptacle can be bearing in movably perpendicular to direction of feed to be accepted in the framework, and accept framework and can be bearing in the frame movably along direction of feed, wherein, accept framework have two be located in both sides that conveying device is other and be used in the middle of the linear guiding device of receptacle.Accept framework within the scope of the invention and not necessarily refer to a kind of structure of self sealing that supports.Exactly, especially also think a kind of three sides, that is the supporting of U-shaped configuration, this is rational to both sides at the other supporting arrangement of conveying device for receptacle in the middle of realizing.Linear guiding device especially it is also conceivable that the drive unit of employing by synchronous belt, and its characteristics are, even also can fricton-tightly move under the situation of maximum dynamic force when motion.

Typically, with after the conveying device being a same banded discharger that comprises many belt laces formations that extend parallel to each other.For when conveying device moves, especially also when it faces that side shifting of discharger, can guarantee continuous transition between conveying device and discharger, conveying device can be bearing on the discharge framework jointly with discharger, the discharge framework is then adjustable, and is especially removable and/or be bearing on the frame pivotally.

Make long cover watt (a part part) in order before transferring to section on the conveying device, can also on middle receptacle, to provide enough positions to be used to, the pallet of middle receptacle has the length perpendicular to the direction of feed metering, it is equivalent to cut into slices perpendicular to the width of direction of feed metering twice at least, preferably at least three times.

For avoiding going up the difficulty on the generation time in the urgent stage in the often time that middle receptacle " pushes ", middle receptacle, from its holding fix, should be able to be in a plane that forms by middle receptacle pallet, along being transferred the same direction that device is discharged, introduce in the projection of food bar cross section with section.

Following measure is used for the identical purpose that cutting process was eased aspect the time: middle receptacle is in a plane that forms by middle receptacle tray surface, enter from a side in the projection of food bar cross section, this side is relative with the section that is forming breaks away from food bar there under the gravity effect that side.

The specific embodiment

Among Fig. 1 to 5 with fragmentary, perspective view and food bar 2 (for example sausage, the cheese etc.) cutting equipment 1 in Fig. 6 to 10, represented with side view, an only cutter sweep 3 of expression in Fig. 6 to 11 is arranged, it has a for example sickle-shaped blade 5 around rotating shaft 4 rotations, but also can be different with it, be a kind of form of the planetary cutting disc that on rocking arm, rotates.Blade 6 is determined a cut surface 7 by rotation, and it is perpendicular to longitudinal axis 8 orientations of food bar 2.The direction of feed ground that longitudinal axis 8 is parallel to arrow 9 explanations extends, and food bar 2 is presented to the blade of cutter sweep 3 by the feed arrangement 10 that only schematically illustrates along this direction.Feed arrangement 10 has a gripping apparatus 11 that can advance along direction of feed (arrow 9) in the top, its grapple 12 insert food bar 2 back to the rear end of blade 5 and thereby form the form fit formula and connect.Not only gripping apparatus 11 but also two feeding belts that do not have detailed expression have a kind of design by prior art, so here need not to describe in detail.Above-mentioned feeding belt is supported food bar 2 and is equipped with the form fit formula jockey (spike) that is used for anti-sliding stop when needed in the side.Consequently, food bar 2 under any circumstance all can be presented along direction of feed (arrow 9) with high precision by feed arrangement 10, and this is significant for the section physical dimension that obtains high accuracy.

In that side of cut surface 7, be provided with discharger 13, conveying device 14 and middle receptacle 15 side by side and each other back to food bar 2 and feed arrangement 10 with overlapping.Middle receptacle 15 is fork-shaped, and have a plurality of sharp tooth pallets of arranging 16 parallel to each other and equidistant with one perpendicular to pallet 16 extensions and the crossbeam 17 that is connected with pallet.Middle receptacle 15 is bearing in that accept in the framework 18 and make it can be perpendicular to direction of feed, that is is parallel to cut surface 7 and moves.Crossbeam 17 is in two vertical ends are bearing in a linear guiding device 19 respectively for this reason, and the latter is in the inside of vertical strut 20 of accepting framework 18 respectively.Middle receptacle 15 realizes that by a synchronous belt 21 it is connected with crossbeam 17 by a male part in the both sides of middle receptacle 15 respectively along the driving of linear guiding device 19 directions.

Be designed to and can accept framework 18, can in Fig. 1, schematically illustrate along what (four-headed arrow 22) direction was parallel to that direction of feed (arrow 9) moves, however frame 23 inner the moving of expression in detail in Fig. 6.Adjustability for example realizes by the cylinder 24 of two hydraulic pressure or air-operated control, connect the bottom 26 of accepting framework 18 on its piston rod 25 separately.As Fig. 1 represents, can only see the piston rod 25 (it only is expressed as linear for simplicity in Fig. 6 to 11) that in fact is designed to crooked shape among the figure, accept framework 18 and implement supporting and adjustment by (can not see in Fig. 6 to 11) two cylinders 24 with two relevant piston rods 25, they act on the opposite side of accepting framework 18.Do not have to represent in detail a servo drive that is located at lid 27 back of accepting framework 18 in these figure, it is used for moving middle receptacle 15 by synchronous belt 21.

Conveying device 14 comprises many equidistant each other belt laces 29 of arranging also a public conveyor surface 28 of side formation thereon, they are around two slewing

rollers

30,31 guidings with the cannelure that is used for belt lace 29, and one of slewing rollers can drive by servo drive.Clear spacing between the adjacent belt lace 29 is slightly larger than the width of pallet 16 perpendicular to fork-shaped pallet 16 length meterings.Because the calibration size of conveying device 14 belt laces 29 is corresponding to the calibration size of middle receptacle 15 pallets 16, so the latter can insert in the space between the adjacent belt lace, this has decisive significance from middle receptacle 15 to the transfer of conveying device 14 for the section that the back will illustrate.

Discharger 13 and conveying device 14 the same many belt laces 32 that comprise, but their width is more much bigger than the width of conveying device 14 belt laces 29.The slewing rollers 33 of discharger 13 are arranged in such a way near the slewing rollers 30 of conveying device 14, even also

belt lace

29,32 does not bump against mutually, guarantee noiseless thus and do not influence section row ground to shift to discharger 13 from conveying device 14.

Discharger 13 is bearing in the discharge framework 34, and it can be bearing in the frame 23 pivotally around slewing rollers 35 rotating shafts.Attaching troops to a unit of discharger 13, be connected with another (hydraulic pressure or the air-operated control) cylinder 36 or its piston rod 37 that are covered by cabinet among Fig. 1 but in Fig. 6, can see in that end of discharger 13 slewing rollers 33.In this case, piston rod 37 shifts out from cylinder 36, not only impels upwards revolution of discharge frame 34, and causes parallel mobile with the conveying device 14 of piston rod 37 couplings equally.Correspondingly be connected on piston rod 37 based on the collimation and the conveying device 14 of cylinder 36 longitudinal axis 38 with direction of feed (arrow 9), the continuing surface 39 that conveying device 14 is made of belt lace 29 surfaces, all the time its parallel orientation of Bao Te with respect to cut surface 7, that is perpendicular to direction of feed (arrow 9) orientation.Because being articulated and connected between conveying device 14 and discharger 13, folded angle between continuing surface 39 and the discharge face 40 that constitutes by belt lace 32 surfaces, with the position of conveying device 14, the position of the piston rod 37 of cylinder 36 change just.Another synchronous belt 40 means it is a coupling device between conveying device 14 slewing rollers 30 and discharger 14 slewing rollers 35.

The processing step of representing referring to accompanying drawing one by one describes in detail by method of the present invention:

In Fig. 1 to 5, at first illustrate by five imbricates self deposit one by one the section forms part form.Owing to taken cutter sweep 3 away and comprised 1 feed arrangement 10 of food bar 2, so can most clearly find out the correlation between conveying device 14, middle receptacle 15 and the discharger 13.

Fig. 1 represents a kind of situation, just finishes and is placed on the conveying device 14 by the portion that five sections constitute for one at this moment.Blade whenever turns around and downcuts a slice from food bar 2, wherein twice each other between in succession the cutting belt lace 29 of conveying device 14 continue to move " covering a watt size " along direction R1 towards discharger 13 so that cause only partly overlapping so-called flakey or imbricate to deposit.

Fig. 1 represents a kind of situation, and this moment, blade 5 downcut in uppermost last a slice completeization just in time, and middle receptacle 15 still is in its holding fix, and it has maximum distance by correspondingly controlling synchronous belt 21 from discharger 13 in this position.The cylinder 24 that will be like this can't see in this moment by control and thereby adjust by the relevant piston rod 25 that moves the height of accepting framework 18 and thereby also have in the middle of the height of receptacle 15 pallets 16 upsides, promptly, receptacle 15 is by activating the drive unit of synchronous belt 21 in the middle of making, can move along direction R2, meanwhile be not placed on the conveying device 14 that a uppermost a slice of completeization contacts with crouching towards discharger 13.

Fig. 2 represents that middle receptacle 15 is in it and accepts the position, and this moment, it was in the distolateral vertical below of food bar, and thereby a sheet that just in time downcuts can be placed on the surface of its pallet 16.Because the rotation of blade 5 is the same with the feed motion of food bar 2, (that is food bar 2 is cut fully until residual section that is in except that grapple 12 wherein) is with constant rotating speed in whole cutting process, that is angular speed carries out unchangeably, so middle receptacle must be in the shortest time, that is between making two, accept the position from its holding fix arrival.This needs very big dynamic force during receptacle between at the volley, can realize very big dynamic force by having the powerful servo-driver that is used for synchronous belt 21.The section that is forming of new in principle portion can let droop the part of its cutting-out under the gravity effect, even might be contact with that last section of complete before portion, but can accept or promote a new sheet that forms sagging or that part of being stored before it downcuts from food bar 2 fully because enter middle the receptacle 15 in the space between blade 5 and complete before that portion, thus cause this new section fully with for sleeping in being placed on the middle receptacle 15 in accordance with regulations.In addition, it can also be seen that that complete portion is based on the continuation campaign of conveying device 15, with its preceding two arrival dischargers and be in transition phase by Fig. 2.

As seen from Figure 3, second of current this portion that will form is downcut and leaves on the middle receptacle 15.In order also to cause imbricate to deposit on middle receptacle, middle receptacle 15 continues to move along the direction R3 perpendicular to direction of feed and covers a watt amount, thereby makes second and first of this new part only to overlap.Therefore at " pushing " the direction R2 of middle receptacle 15 and then continue not move between the direction of motion R3 reverse.Based on conveying device 14 and discharger 13 continuation campaign in addition, that complete portion is on the discharger 13 now basically fully before making it.

Press Fig. 4, middle receptacle 15 carries out the transition to evacuate position now, this moment is maximum from the distance of holding fix, pallet 16 inserts in the space between the adjacent belt lace 29 by the ascending motion of conveying device 14, and those sheets that are in contact condition with middle receptacle 15 pallets 16 are in advance transferred on belt lace 29 surfaces.When transferring on the conveying device 14 with these sheets, or in the short time before or after described transfer, downcut new this portion that will form the 3rd, it is moved further perpendicular to the corresponding sports of direction of feed or the motion of conveying device 14 by middle receptacle 15, deposits so that can carry out imbricate continuously.Before that portion of completeization during this period on discharge band 13 further along moving towards the direction of revolving roll 35, in order that further import after this in the packaging facilities, these sections are enclosed in the SB blister-pack there.

At last, how Fig. 5 also represents to add the 4th to this of current formation is a.Here as yet not this portion of completeization only be placed on the conveying device 14, and, compare, towards the direction R1 of discharger 13 segment distance that advanced with section section before this in order to keep imbricate to arrange.Direction R1, R2 are identical with R3.In order to keep its distance from cut surface to return the centre position from evacuate position, avoid with the sheet that has downcut any contact being arranged this moment to middle receptacle 15 during this period.From middle receptacle 15 illustrated centre positions, it can rise to its holding fix again at next step, and this realizes by promoting the whole framework 18 of accepting.After another makes the 5th of current this a completeization in cutting, arrive the original position of pressing Fig. 1 again.

To make imbricate part different with pressing Fig. 1 to 5, now, in Fig. 6 to 11 explanation make by exactly up and down the sheet of vertical stacking forms part.Although this is not by method of the present invention, for the purpose of understanding, should here be illustrated.In addition, adopting also can be by the imbricate sheet row that pile up corresponding to one of the process manufacturing of Fig. 6 to 11 by equipment of the present invention.These parts are enclosed in the plastic film packaging in packaging facilities, and are offered the supermarket as the SB packaging unit by after finishing on the equipment of the present invention.

Similar with the situation of pressing Fig. 1, Fig. 6 has also represented one and has been in portion complete on the conveying device 14.Blade 5 still is in food bar 2 cross section inside, but leaves cross section Q in next moment, so that then invade one section food bar of sending to 2 during this period again and begin to separate a slice down.Receptacle 15 carries out the transition to the position of accepting shown in Figure 7 from holding fix shown in Figure 6 in the middle of just in time in the above-mentioned time, that is especially uses big dynamic force " to push ".Therefore the blade 5 cross section Q that enters food bar 2 carries out from this side S1, and middle receptacle 15 then enters cross section Q from opposition side S2.

Because after the manufacturing of a slice begins down, on the receptacle 15, only be 41 tops, surface that are in this complete portion slightly fully in the middle of this a slice being left in so middle receptacle 15 pushes position (accepting the position) at it.When these sheets are downcut, as shown in Figure 7, they also at first leave on the middle receptacle 15, this has caused utilizing following principle, that is, a sheet that is forming, sagging free end under the gravity effect, before this a slice is separated from food bar fully, in the middle of being placed on the surface of receptacle 15 or left in advance on those slice surfaces there.The advantage of this method is to deposit to be of high quality because section will never be in the free falling state, that is will never be in neither with food bar 2 also not with the receptacle state of contact.Adopt this method to prevent that reliably section from loose throwing out of control, as when the landing distance of sheet is longer, unavoidably can taking place.In addition as seen from Figure 7, the motion of complete part by conveying device 14 is towards discharger 13 segment distance that moved.

Second of the new portion that Fig. 8 indicates to form is at its a kind of state that separates not long ago from food bar 2 fully.With deposit different by the imbricate of Fig. 1 to 5, by Fig. 6 to 11 vertical stacking deposit, in the middle of only requiring receptacle 15 its be used in deposit purpose during, need only move along direction of feed, in order that the sheet that forms at the next one keeps constant with the distance between cut surface and the storage surface, and thereby do not change storage condition yet.That complete before portion under state shown in Figure 8, is in the transition region between conveying device 14 and the discharger 13.

Situation when the 3rd of the new portion that Fig. 9 indicates to form just in time separates.The portion of completeization is transferred on the discharger 13 and is further continued motion there before this.

In case it is enough far away that the interstitial area that last complete part is shunk from wedge shape between blade 5 and discharger 13 leaves, conveying device 14 just can move upward along direction of feed again by the slewing rollers 33 of coupling with it of discharger 13.In this way, that is based on the relative motion between conveying device 14 and the middle receptacle 15, be set to the same at least with the surface of middle receptacle 15 pallets 16 highly by belt lace 29 surfaces, receptacle 15 is in off working state in the middle of can making.Figure 10 represents this transfer moment.

From now on, in next procedure, middle receptacle 15 continues sinking (or conveying device 14 promotes) segment distance again, from food bar 2 cross section projections, withdraw from (centre position perpendicular to direction of feed after this, referring to Fig. 5), in order that carry out the transition to holding fix shown in Figure 11 again at next procedure.Middle receptacle 15 can remain there for a long time, piles up until downcutting forming last a slice of this portion and leaving in.Then, after this complete portion sinks in a small amount,,, it just can receive next section in conveying device 14 so accepting the position at it for receptacle 15 in the middle of then pushing provides the space that needs.
