1、APRICOT PITTING MACHINEMalcolm W.Loveland,Emeryvile,assignor to Atlas-Pacific Engineering Co,a corporation of Califorma Filed May 25, 1966, Ser. No. 552,S6110 Claims. (CI. 146-28)This invention relates to an apricot cutting machineand more particularly relates to a machine wherein anapricot is align

2、ed on its suture axis by a prior machineand then passes under a floating knife which cuts theapricot substantially on its suture plane and thereafter apit kicker removes the pit from the apricot.Most apricots are of a free pit nature and it is onlynecessary to cut the fruit in half and the pit willo

3、rdinarily fall out. However, there is always a certainpercentage of apricots wherein the pit is not free andtends to stick to one or both halves of the cut apricot.Apricot cutting machines having a floating non-rotating knife have heretofore been known such as that described in Patent 2,735,466 wher

4、ein theapricot is rolledunder a floating knife, the knife severing the apricot andthereafter a hook or tail forminga part of the knife dislodges the free pit as the apricot passes underneath thehook. Such a structure works wellwith free pit apricotsbut tends to jam-up when an apricot with a stuck pi

5、t isencountered. On hand-fed machines, this occurrence iseasily rectified by the operator but on modern automaticmachinery, many apricots are damaged before such ajam will clear itself.It is a primary object of the present invention to provide an apricot cutting machine wherein the pits are dislodge

6、d in a positive manner.Another object of this invention is to provide anapricot cutting machine having an oscillating pit kickerwhich positively dislodges stuck pits.A still further object of this inven'ion is to providean apricot cutting machine wherein a shroud covering theknife has a pluralit

7、y of resilient fingers, imparting a positive rolling motion to the apricot thus facilitating cutting.A still further object of this invention is to providesuch a structure wherein the shroud can be adjusted relative to the knife whereby the machine will accommodateapricots of various sizes.Still ano

8、ther object of this invention is to provide adevice wherein the knife and kicker are mounted on acommon carriage which can be raised or lowered to accommodate apricots of various sizes.In the drawings forming part of this application:FIGURE 1 is a side view, partly in section, of a deviceembodying t

9、he present invention.FIGURE 2 is an end view on the line 2-2 of FIGURE 1.FIGURE 3 is an enlarged side view of the cutting andpit dislodging mechanism shown in FIGURE 1.FIGURE 4 is a section on the line 4-4 of FIGURE 3.FIGURE 5 is an enlarged section through an apricotshowing the action of the cuttin

10、g knife.FIGURE 6 is a section through an apricot showing theaction of the pit kicker.FIGURE 7 is a partial view similar to FIGURE 6showing another form of pit kicker.FIGURE 8 is a section of a still further form of pitkicker.FIGURE 9 is a section on the line 9-9 of FIGURE 1.FIGURE 10 is an enlarged

11、side view of a pit kickerconstructed in accordance with the present invention.FIGURE 11 is a perspective view showing the relationship between the cutting knife and shroud.Referring now to the drawings by reference characters, the device of the present invention, generally designated 12, is mounted

12、over the discharge end of an apricotorienting and propelling mechanism generally designated14. The orienting mechanism 14 is not described in detailsince it forms no part of the present invention. However,it can be of the type shown in co-pending patent application, Ser. No. 452,479, filed May 3, 19

13、65, now Patent No.3,272,311, wherein a plurality of lanes are provided,each of which includes moving belts 16 and 18 arrangedin a generally V-shaped configuration for the purpose ofpropelling the apricots down a desired path. In the embodiment illustrated。five such lanes are Provided although it wil

14、l be obvious to those skilled in the art thata smaller or larger number of lanes might be employed.The overall structure includes side frame members 20and 22 which slideably support threaded shafts 24 and26 mounted on guides 28 and 30. At the upper end ofeach threaded shaft is a sprocket 36 which is

15、 internallythreaded. The sprockets 36 have a hexagon on their uppersurfaces so they may be turned with a wrench.The lowerhub of the sprocket has a flange 32 which fits into agrooved block 34 affixed to the guide 28. As the nutsprocket is turned on the threaded shafts 24 and 26 theshafts are moved up

16、wards or downwards depending ondirection the sprocket is turned. The sprockets aretied together by means of a roller chain 38 which passesover a tightner sprocket 40. By this arrangement whenone sprocket is turned, the other sprocket is turned a likeamount. A carriage for supporting the cutter assem

17、bliesis provided by the transverse bars 42 and 44 which arelinked together with connectors 46. The connectors 46are securely attached to the threaded shafts 24 and 26so as to rise and fall with the shafts and maintain theirparallel relationship with the belts 16 and 18. Attached to the carriage is a

18、 motor mount 52 which rises and fallswith the carriage.The cutter assembly 12 is mounted on a sub-frame54 to which are attached vertical guides 56, 57, 58, and59 which are arranged in pairs, forming close fitting slotsin which knife 62 can slide up and down freely. Theknife 62 has slots 60 therein a

19、nd is held in place on thevertical guides by means of the bolts 64 and 66. Thus theknife can move up or down by the length of the slots.Compression springs 68 and 70 normally bias the knifeto the bottom of the slots 60 and give the knife blade afloating action. Desirably, the springs include guides

20、72to keep the springs from deflecting to one side. Theknife itself has a tip portion 74 and a horizontal portion76. The tip portion 74 makes an angle of about 200 withthe horizontal portion 76. It will thus be seen that theknife has a floating action and can tilt or raise against theaction of the sp

21、rings.Mounted on the knife is the shroud designated 78. Theshroud itself consists of a pair of metal backing members80 and 82 which are mirror images of each other. Blade62 is provided with slots 84 and 86 and the halves of theshroud are bolted into these slots by means of the bolts88. It will thus

22、be seen that the shrouds can be locatedat various heights with respect to the blade edge by adjustment of the bolts 88. The shrouds themselves comprise a rubber liner 90 secured by a suitable adhesive tothe backing members and include a plurality of smallrubber fingers 92 for gripping the fruit. The

23、 front end ofthe shroud is curved upwardly as at 94 to produce awedging action as the fruit first encounters the shroud.The shrouds extend the length of the knife and continueover the pit kicker blade.The pit kicker itself which forms the crux of the presentinvention has been generally designated 96

24、. The pit kickerincludes a vertical forward surfaces 98 and an angularforward edge 100 which forms roughly a 30º angle withthe knife blade. The pit kicker 96 is mounted on an arm102 carried on a pivot 104 and includes an upwardlyextending arm 106 terminating in a cam follower 108.A compression

25、spring 110 mounted between arm 102and support plate 55 urges the pit kicker downwardlyand the cam follower 108 into contact with a cam 112.Cam 112 is mounted on shaft 114 which is driven byprime mover 116 through belt 118. In this manner, thepit kicker 96 is given an oscillatory motion and, sincethe

26、 arc through which it moves is quite small, this motionis almost entirely vertical.The pit engaging portion of the pit kicker can takevarious forms. In the form shown in FIGURE 6 as wellas in the FIGURE 3, the fruit engaging portion 100 hasflat face with square edges so that it either hits the pitwi

27、th its flat face or, if it hits to one side of the pit, thesharp edge between the face and the side of the kicker willtend to engage and dig into the pit. This effect can befurther enhanced in the embodiment shown in FIGURE7. Here the pit engaging edge, designated 100-A is hollow-ground having sharp

28、 ridges on each side of the hollowcenter. As can be seen from FIGURE 7, these sharpridges will tend to engage a pit and dislodge it. The effectcan be even further enhanced in the form shown in FIGURES 8 and 10 wherein the pit is given a serrated edgeas at 100-B. It is obvious that such an edge havin

29、g aseries of sharp points will tend to dig into the pit andpositively disengage it from the apricot.The action of the device is as follows: As an apricotpasses down the V-belts 16 and 18 it is first engaged bythe sloping tip end of blade 62 designated 74.The forward tip of this blade is higher than

30、the highest positionof any apricot to be encountered. Thus the apricot wedgesunder the blade and as the belts propel the apricot forward the knife slices almost into the pit, whereupon theshrouds engage the apricot retarding the upper surface,and give it a positive rotating action.Thus the apricotte

31、nds to roll along the flat portion 76 of the knife makingat least one complete revolution, completely severing theapricot. Desirably, the knife goes just to the -pit andthe action of the shroud is not only to cause the rotatingaction but also to prevent the knife from penetrating theapricot deeper t

32、han is desired. Thus an important aspectof the invention is the adjustability feature wherein theshrouds can be adjusted to give any desired depth of cut.Further, by adjusting the entire carriage, the pressure onthe apricots can be adjusted so that an undue amountof pressure will not be exerted by t

33、he shrouds, tending tocrush the apricots when running large fruit. Since apricotsare ordinarily pre-sorted for size, the machine of the present invention is ideally adjusted to run a single size offruit by means of the two adjustments described above,although considerable variations in size of fruit

34、 can beencountered with reasonably satisfactory results.It has been found that about 4 inch of pit kicker travelis adequate to secure a good job of pit removal. On amachine running at a belt speed of slightly over 800inches per minute, a frequency of 1200 chops per minutewas employed with satisfacto

35、ry results. This gives theblade about three chops at each pit. The action whichprobably happens to a stuck pit is somewhat as follows:With the blade in an up or partially down position, the pitengages the kicker and is stopped in its forward motion.The down stroke would then push the pit some portio

36、nof 1/4 inch out of its contact position. When the kniferetracts the apricot and pit are urged forward further bythe action of the belt combined with the sloping portionof the pit kicker so that the nit is further dislodged byeach stroke. Two or three strokes of the pit kicker probably move the pit

37、downwardly from Va to N inches fromits original location, which is adequate to detach it fromthe apricot half. When comparing the oscillating pit kickerof the present invention with a stationary knife with afixed heel such as shown in the prior art, the number of stuck pits remaining in the cut frui

38、t was reduced by a factor of five to ten.Although the oscillating pit kicker has been described for use in conjunction with a particular type of slitting knife, and is preferably so used,the kicker may be employed with other slitting devices.It is believed obvious from the foregoing that I have prov

39、ided a superior machine for slitting apricots and one which essentially solves the problem of stuck pits.I claim:1. In a drupe pitting machine having means for propelling drupes over a path of travel wherein each drupe is positioned with its suture in a vertical plane as such drupe is delivered to a

40、 cutting station whereat a knife is positioned above the path of travel of the drupe with its blade extending generally in said vertical plane and with the cutting edge on said blade extending parallel to said path of travel whereby the flesh of each drupe is severed into the pit therein at said cut

41、ting station; the improvement comprising:(a) a pit kicker comprising a planar blade having a downwardly extending edge for disengaging a pit in a drupe which has been cut by the knife;(b) means mounting the pit kicker blade in said vertical plane with the forward end of said edge adjacent the end of
