BACKGROUND OF THE INVENTION In general, the invention relates to material depositing apparatus, and more particularly to a crumb dispensing apparatus for streusel type cake products.
It is a well known problem in the baking industry to handle and produce streusel type cake or cupcake products. One considerable difficulty is encountered in trying to deposit measured amounts of the streusel in a uniform and accurate manner on the cake products. For example, if the deposited amount is not accurately measured and properly dispensed, the resulting product, after baking, is uneven, unappealing, and results in considerable waste during the on-line processing. Another of the problems, in depositing the streusel type material, is due to the composition of the mixture itself. A typical type mixture utilized in producing a streusel type cake product comprises approximately a 20 percent shortening, a 25 percent granulated and brown sugar, a 45 percent flour, and a percent combination of almond paste, honey cinnamon and salt. As should be readily understood by one skilled in the bakery art this mixture, if not properly handled and dispensed, will cause considerable clogging and gumming of any dispensing equipment; so as to make high speed production with minimal waste of the ingredients virtually impossible.
These and other problems were overcome by the apparatus according to the invention. The apparatus efficiently handles the streusel type material to control the depositing, and insures that equal amounts are deposited on the cake products in a high speed uniform manner as hereinafter described.
SUMMARY OF THE INVENTION It is therefore an object of the invention to provide an improved depositing apparatus.
Another object of the invention is to. provide depositing apparatus capable of handling streusel type cake materials in a controlled manner.
According to the broadest aspects of the invention there is provided depositing apparatus including material dispensing means, a rotatable cross bored drum postitioned to receive material from said dispensing means in a first position, and means coupled to said drum to cause said material to be deposited in a controlled manner when said drum is in a second position.
A feature of the invention is to provide depositing apparatus useful in producing streusel cupcake type products comprising a housing having an entrance port coupled to a source of material and an exit port positioned to discharge said material in a number of controlled deposits, a drum mounted coaxially in said housing for rotatable movement, said drum having a series of Y- shaped bores, means for intermittently rotating said drum so that each branch in each Y-shaped bore of said series communicates first with said entrance port to be filled and then with said exit port for dispensing said material, and means are coupled to assist the filling and dispensing of said material.
BRIEF DESCRIPTION OF THE DRAWINGS The above objects and features of the invention will be better understood if reference is made to the following description taken in conjunction with the accompanying drawings, in which:
FIG. 1 is a front view of the apparatus according to the invention;
FIG. 2is a side view of the apparatus according to the invention;
FIG. 3 illustrates the position of the cross bored drum in a filling position;
FIG. 4 is a drawing showing the cross bored drum in a depositing position; and 1 FIG. 5 illustrates the means of controlling and timing the operation of the apparatus according to the invention.
BRIEF DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to FIGS. 1 and 2, the general concept and design of the apparatus according to the invention will be described. A frame 11 is positioned to mount the apparatus over cupcake pans 12 which are moving on a conveyor belt 13. Each pan 12 comprises a series of twelve cups, 12 through 12 across its length and three rows of cups 12a, b, c.
An upper storage hopper 14 is mounted on the frame and equipped with a series of power driven agitator fingers Man and l4bn to continuously break up the source material to prevent packing. A variable applicator drive unit 15, more particularly described in connection with FIG. 5, drives the agitators by means of coupling shafts 14c and Md. The variable drive for these agitators is coupled from the applicator reel drive as illustrated in FIG. 5. The material to be deposited which is placed in the upper storage hopper 14 is broken up into varying size lumps by the agitator fingers and forced into the lower applicator hopper 16. The hopper 16 is equipped with an eight-blade applicator reel 16a mounted and driven by shaft 16b from applicator drive unit 15. The applicator reel 16a in the lower hopper 16 wedges the material through a perforated screen 16c from where it falls directly into the discharge manifold 17 mounted in the frame 11 below hopper 16. The perforated screens are removable and fixed to the lower hopper by means 16d, so that it may be cleaned and different screens with varying size holes may be used depending on the product.
The discharge manifold 17 directs the waterfall flow of the material coming from the lower hopper into the top of the multiple number of individual tubes 18, through 18 there being one tube for each of the cups in pan 12. The feed tubes are coupled by collars 19 to drum housing 20. Rotatably mounted within the drum housing 20 is a cross bored 21 having 12 serially positioned Y-shaped cross bored holes 22. In a first position the cross bored holes are first filled by the flow of the material from the manifold 17, and in another position deposit the material through the discharge nozzles 23 which are positioned above the cups in pan l2. Rotatably mounted with the cross bored drum shaft 210 is a first rotating actuating cam 24 which actuates valve number 1 to control the air pressure from the air tank source 25 to the air connecting tube means 26 and 27 mounted on the drum housing. In a similar manner, another control cam 28 controls the actuation of valve number 2 which controls the air pressure from source 25 into each one of the air tubes 29a through 291. The
tubes are coupled from valve number 2 to the multiple number of individual feed tubes 18.
FIG. 3 illustrates the filling position of the cross bored drum 21 which is rotatably mounted within drum housing 20. Drum housing 20 has an entrance port 2011 and an exit port 20b. During the filling of the Y-shaped cross bored holes 22 the material drops through the entrance port and completely fills the Y-shaped cavity 22, the material filling being assisted by air pressure which is coupled by tubes 29 from air valve number 2 as illustrateed in FIGS. 3. and 2. The drum housing 20 includes air connecting tube means 26 and 27, the entrance of which is blocked during filling of the bore by the solid portions of drum 21.
FIG. 4 illustrates the position of the rotatable drum during depositing of the material from exit port 20b. It will be observed that during the depositing sequence the entrance port 20a is blocked by the solid portion of the cross bored drum 21, and the air connecting tube means 26 and 27 are cleared to permit the air assisted flow of the material accumulated within cavity 22 to be deposited. The air assist insures the complete removal of the volume of material accumulated, to insure controlled depositing of the material into the cups in pan 12.
Referring now to FIG. 5, the control and timing means for the operation of the apparatus discussed above is illustrated. The entire mechanism is activated, stop or start, by switch means 30 which is activated or closes a circuit to power source 31. The pan 12, as it passes underneath the individual discharge nozzles 23, is timed to cause the energization of the slip-type disc clutch 32 and 33 to enable the speed-controlled motors 34 and 35 to respectively drive shafts 21a and 16b, and via coupling means 36 shafts 14c and 14d. The motors are individually gear adjustable in a manner well known in the art. The timing of the air from valve number 1 and number 2 is controlled by the rotating earns 24 and 28. Cam 24 is in the shape of a flat disc having three protruding actuating portions 24a, 24b and 240 which are spaced 120 apart and intermittently act on valve number 1. When cam portion 24a, 24b and 24c activates valve number T, air from air source tank 25 is caused to be coupled by the out air coupling tube of the valve to each of the air connecting tube means 26 through 26 and 27 through 27 During this time the position of the cross bored drum 21 is as illustrated in FIG. 4.
Camming disc 28 also has three protruding cam activating portions 28a, 28b and 280 which are spaced 120 apart, but out of phase with the protruding portions of disc 24 by 60. After portion 24a of disc 24 leaves its actuating position of valve number ll, then valve number l shuts off the air supply, and then valve 28a comes into position to actuate valve number 2 and causes the air from source 25 to be coupled by lines 29 to the feed tubes to assist in again filling the Y-shaped cross bored holes 22. At this time the cross bored drum is in the position illustrated in FIG. 3. When cam 24a was in the activating position, the material was deposited into cups 120, and during the travel of the pan from the position of cups 120 to 12b, the valve number 2 was activated by portion 28a so that when cup 12b is in the position to be filled, cam portion 23b activates valve number 1 and a complete deposit of the material is made into cups 12b. This cycle repeats itself three times for each pan 12 so that equal and controlled deposits are made into each row of 12 cups. It is of course understood, that during this time the agitator hopper M and the applicator hopper 16 are rotating at a predetermined speed to insure a proper flow of material into manifold 17.
Each pan causes the following sequential operations: turning on of system, filling the Y-shaped bores with an air assist, depositing in a row of cups with an air assist, repeating the filling and dropping two more times, and turning off of the system.
Reviewing the overall operation of the system in connection with the above, the objects and features should now be apparent as well as alternative embodiments to those skilled in the art. The material to be applied is placed in the upper storage hopper where agitator fingers break up the material in varying size lumps which are forced into the lower applicator hopper. The applicator reel in the lower hopper wedges the material through a perforated screen where it falls into the discharge manifold directly below. The manifold directs the waterfall flow coming from the applicator housing into the top of multiple spouts in the drum housing. The material is directed and air assisted into individual ones of the Y-shaped cross bored holes. Cam control means are coupled to the drum to control depositing into the cups of the pans which are continuously traveling underneath the discharge nozzles positioned at the bottom of the drum housing. The entire mechanism is activated, start or stop, by a switch means which is gripped as each individual pan frame passes underneath the nozzles. The speed of the reel applicator is variable and controls the amount of material deposited in the individual cups on each'cycle, and the cross bored drum drive is variable and synchronizes the deposit from each Y-shaped bored hole into the cups of the pan without overflow to the sides between the multiple cups in each row of the pan. In order to compensate for variations in spacing between pans as they move along under this device on the conveyor, a slip-type disc clutch and locking cam are used for the purpose of indexing each series of three rows of cups in one pan frame. This also obviously eliminates any progressive error in depositing directly into every cup without overflow.
