14 Claims.
This invention relates to a dough twisting machine, and it Consists in the constructionsarrangements and combinations herein described and claimed. e
It is an object of the invention to provide a novel and simple construction of apparatus for twisting pairs of molded rolls of dough, preliminary to baking, and to this end the invention consists in means for automatically feeding paired rolls to a pick-up drum or the like and pinching opposite ends of the rolls for the purpose of securing the rolls together for twisting action between a rotating disk and stationary platform, the mechanism being driven from a single power unit.
It is also an object of the invention to provide a mechanism which is portable, making it possible to transfer the apparatus to diierent molding machines, as desired.
It is also a further object of the invention to provide mechanism which is adjustable to various lengths of dough as well as to provide a device which may be readily regulated to operate at a speed in proportion vto the speed of the molding machine. v
It is a still further object of the invention to provide a novel construction of pick-up drum and drive means between the delivery conveyor and the drum.
Additional objects, advantages and features of invention will be apparent from the following description considered in connection with the accompanying drawings, wherein Figure 1 is a side elevation of the machine, partly in section.
Figure 2 is a top plan'view thereof.
Figure 3 is a fragmentary enlarged detail of the feed mechanism between the delivery conveyor and the pick-up drum.
Figure 4- is a sectional View through thejournal of the twister disc, illustrating its mounting and adjustment.
Figure 5 illustrates a pair of rolls of dough as received from the forming machine.
Figure 6 illustrates the dough as received from the pick-up drum prior to twisting.
Figure '7 is a view illustrating the twistedloaf, ready for baking. y e
Attention is now invited to Figures l, 2 and 3 of the drawings wherein there is shownv a dough twisting machine generally indicated bythe reference characterl Hl, and as may be seen in Figure l comprises a platform II mounted upon casters I2 for ready movement of the apparatus to a desired forming machine, not shown.
At one end of the platform II there are mounted paired uprights I3 suitably spaced to support at their upper ends, rollers I4 and I5 around. which there ls trained an endless belt I6 for receiving formed rolls of dough from the 5 forming machine, a chute II of which is shown.
In advance of the foremost upright I3 a pair of uprights I8 are mounted, one on either side 0f the platform, and between these upright-s there is revolubly mounted a pick-up drum I9.
The drum or carrier I9 is formed as a cylinder in which a plurality cfperlpherally open pockets 20 are formed, the leading edge 2| of which is slightly arcuate in the direction of rotation permitting ready discharge of pinched rolls of dough l5 from the pockets of the drum.'
Upony one end of the drum laterally extended pins 22 are provided, adapted to actuate the conveyor I6 intermittently, as will appear as the description proceeds. y
The uprights I8 are of a height-extending a substantial distance above the upper periphery of the drum I9 and revolubly mount a shaft 23. Upon the shaft 23 there are secured a pair of pin wheels 24 eachof which comprises a hub and 25 a like number of radial spokes 25 as there are pockets 29 of the drum. The spokes 25 are suitably mounted at'their ends and of a length stopping short of the bottoms of the pockets 2G.
The shaft 23 is longitudinally slotted and the hub of each pin wheel 24 has a set screw 26 complemental to the slot whereby the pin Wheels may be rigidly secured tothe shaft.
Since the machine is adjustable to accommodate various lengths of dough lateral adjustment of the pins is necessary, and this is accomplished by loosening `of the set` screws 26 lpermitting sliding movement of the wheels 24 to a position on the shaft 23 so that the ends of the arms 2i? will contact and compress respective ends of the dough in the operative pocket. The pin wheels 24 will be rotated by the drum I9 through contact with the dough in the operative pocket.
In advance of the drum I9 there is an upright bearing post 21, the upper end of which revolubly mounts a dough-twisting disk 29 cooperable with a stationary platform 29 suitably supported there beneath. Obviously, the disk 28 must be adjustable with respect to the platform 29 in order to regulate the amount 4of twist imparted to the dough, as well as to accommodate varying diameters of formed dough, and an example of such adjusting means is shown in Figure 4, attention being directed to this figure. The post 2i is exteriorlyv threaded' and axially of the post there is formed a well 30 housing a ball thrust bearing 3|. The bearing 3| has fixed thereto a revoluble upright adjusting bolt 32, threadedly engaged in a. yoke 33 rigidly engaged with the hub 34 of the disk 28. 'I'he hub 34 may include roller or ball bearings 35 providing free rotative action about the post 21. A cap nut 36 engaged upon the upper end of the post 21 insures retention of the bearing assembly 3| and `bolt 32.v Adjustment of the disk 28 upwardly or downwardly upon the post 21 is accomplished by loosening the set screw 31 androtating the adjusting bolt 32 in a direction to raise or lower the disk 28- as desired, thereby varying the spacing between the disk 28 and the platform 29. After adjustment is obtained, the set screw 31 is again rotated to impinge upon the adjusting bolt 32.
An endless conveyor 38 is suitably mounted upon the platform |I, positioned between the drum I9 and the platform 29 and functions to receive dough from the pockets 2|! and convey the dough to the platform 29 for twisting action as will be described, hereinafter.
The formed dough deposited upon `the conveyor I6 must be fed to the pockets 2l) of the drum in pairs and in timed relation in order that each pocket will receive a pair of formed rolls of dough, and in the present instance, I have shown a spur gear 39 fixed to the shaft 40 of the conveyor I6. yIn mesh with the gear 39 there is a gear 4I fixed to a stud shaft 42 carried in a suitable bearing block 43 on the forward standard I3. It will beapparent that upon rotation of the gears 39 and 4|, the conveyor IG will be moved in a direction to advance the dough towards the pockets of the drum. An actuator lever 44 is free on the shaft 42, extended in the direction of the drum I9 and of a length to be contacted by the pins 22, progressively, upon rotation of the drum. The lever 44 normally occupies a position substantially as shown in dotted lines in Figure 3, although the position of the lever 44 may be variedupon adjustment of the stop screw 45 carried in a bracket 43 `on the foremost standard I3. Obviously adjustment of the screw 45 will regulate the stroke or movement of the lever 44 which in turn regulates the degree of rotation of the gears 39 and 4|, and consequently the degree of movement of the conveyor I6. Thus, the conveyor I6 may be moved in timed relation to the rotation of the drum.
'I'he actuating means between the lever 44 and the gear 4I is in the ,form of a ratchet composed of a pawl 46 pivoted as at 41 to the lever 44, the free pawl adapted to engage teeth 48 of the gear 4|. A light leaf spring 49 functions to hold the pawl 46 engaged with the teeth, yet permits the pawl to become suflciently disengaged from theteeth to allow the lever 44 to return to its normal position when released from a pin 22.
A conveyor 5|) is also carried by the platform adapted to receive the twisted rolls, driven through any suitable means.
The drive'for the drum I9, disk 28 and conveyor 38 will now be described. A suitable motor 5| is secured upon the platform I| and preferably includes a reduction gearing, generally indicated at 52, for driving a sprocket wheel 53. The shaft 22-a has fixed thereto a sprocket wheel 54 and trained around these gears there is a sprocket chain 55 affecting a positive drive for belt trained about these pulleys provides movement of the conveyor.
Upon the opposite side of the drum I9, the shaft 22-a has fixed thereon a pulley 59. A standard 60 (a portion of which is shown in Figure 1) supports a double pulley 6|, the upper one of which receives a belt 62 from the pulley 59. 'I'he lower pulley of the double pulley 6I is aligned with a pulley 63 fixed tothe yoke 34 of the disk 28, and a belt 64 trained about these pulleys provides rotation of the disk.
The ratio of the pulleys and gears employed will be such as to drive the various devices at a speed commensurate with the output of the forming machine.
The operation The operation will be understood from the following description.
'I'he formed rolls of dough will be deposited upon the conveyor I6 from the chute I1 and with rotation of the drum I9, a pin 22 will encounter the lever 44 moving thelever upwardly and since the ratchet 46 is in engagement with the teeth 48 of the gear 4I rotation will be imparted thereto with consequent rotation of the gear 39 and forward movement of the conveyor to advance two of the rolls into the adjacent pocket 20 of the drum. The pockets 2U are only of such depth as to accommodate two rolls of dough, the third following roll of dough being held back slightly outward of the periphery of the drum. However, if the third roll should move forwardly by gravity, as indicated in dotted lines, the periphery of the drum will move the roll backwardly without deforming the dough. The drum continues to rotate, advancing the pockets toward the pin wheels 24 until one of the spokes' 25vof each wheel engages respective ends of the dough, causing a compression or pinching of the rolls so that they will adhere. Further rotation of the drum will deposit the pinched rolls upon the conveyor 38. Of course, after contact and release between a pin 22 and lever 44, the lever will fall back to its normal position, by gravity, in readiness for contacting engagement with a following pin 22, making a continuous feed of paired rolls of dough into the respective pockets. y i v The conveyor 38 being driven advances the dough up to the receiving edge of the platform 29 at which point the rotating disc 28 frictionally contacts the dough. The dough will be deposited upon the platform with one end disposed toward the axis of the disc, the other end being presented in the direction of the periphery thereof, and consequently the end adjacent the periphery will be caused to rotate at a higher rate of speed than the .end adjacent the periphery, this difference in rotation causing a twisting together of the two rolls of dough which is nnally discharged upon the conveyor 50. The twisted rolls are then taken from Vthe latter conveyor and placed in pans for baking. I 1
