Definitions

  • a base plate which serves to close the major portion of the lower opening of the container is mounted via oscillating support elements to the rear wall of the container.
  • An oscillating or vibration drive mechanism disposed behind the rear container wall serves to place the base plate into oscillatory movement.
  • the marginal edge thereof which, together with the forward wall of the container forms a throughpassage slit for the material to be strewn, is primarily moved up and down, whereby the upward movement, at least at the start thereof, occurs in jerky fashion.
  • additional means are provided for independently adjusting the basic width of the aforementioned throughpassage slot or slit.
  • the present invention broadly relates to equipment utilized in baking operations and, more specifically, pertains to a new and improved strewing apparatus, especially for baking installations, which apparatus is of the type possessing a container for the material to be strewn which, in cross-section, narrows towards its bottom or lower end and incorporates a front container wall and a rear container wall.
  • Pastry dough of the most different composition nowadays during the course of its processing into finished products, must be strewn with the most different type of fine-grained to coarse-grained materials.
  • the most different types of apparatuses there are available presently upon the market the most different types of apparatuses.
  • the prior art constructions contemplate the provision of either to and fro moving components, or through the action of shaking or jarring movements, to rub or shake the material to be strewn through a horizontally arranged sieve-like surface.
  • the quantity of material which is dispensed can be controlled by varying the employed type of sieve as well as by varying the intensity and the course of the previously mentioned rubbing or jarring movements.
  • Yet another significant and equally noteworthy object of the present invention relates to an improved construction of strewing apparatus for scattering materials, particularly during baking operations, which apparatus is relatively simple in construction, extremely reliable in operation, not readily subject to breakdown, and can handle in extremely efficient and reliable fashion the most varied types of materials to be strewn.
  • the inventive strewing apparatus is generally manifested by the features that a base plate which closes the major portion of the lower opening of the container is mounted by means of oscillatory or vibration mounting elements at the rear wall of the container, and this base plate can be placed into oscillatory or vibrational motion by means of an oscillation or vibration drive mechanism situated behind the rear container wall. Due to this oscillatory motion the marginal edge of the base plate which, together with the front container wall, forms a throughpassage opening or slot, can be primarily moved up and down, with the upward movement at least at the start thereof occurring in jerky-like fashion. Further, the invention contemplates that additional means are provided for independently adjusting the basic width of the throughpassage slot mentioned above.

  • FIG. 8 is a graph illustrating the sawtooth-like movement of a material particle subjected to the jerky-like oscillatory movement of the base plate.
  • the exemplary illustrated embodiment of strewing apparatus which, in particular, is destined to be used in bakery and pastry operations, will be seen to comprise a housing 1 which at the same time forms a part of the container for the material to be strewn or scattered.
  • the rear wall la of the container is inclined with respect to the vertical, as shown, in order that there results a container structure for the strewable material which tapers or narrows towards the bottom.
  • Container sidewalls lb and 1c are fixedly connected with this long container rear wall la.
  • the container has a front wall Id which is pivotably mounted with the side walls Ib, Ic at its upper edge through the agency of the pins or journals 2a, 2b.
  • FIGS. I and 2 that at the lower region of the rear container wall Ia there are mounted at the outside of such wall so-called oscillating or vibrating support elements 3, at which there is mounted the portion 4a of the base plate 4, with such portion 4a being flexed upwardly and extending parallel to the rear wall la, as shown best by inspecting FIG. 1.
  • This base plate 4 extends horizontally beneath the container opening up to the region of the lower edge of the front wall 1d while leaving a small throughpassage opening or slot 5 extending in vertical direction, with the width of such slot being disposed transverse to the downward discharge direction of the material.
  • the pivot point for the base plate 4 is advantageously located at the region of the wall ia, namely the rear wall, and at a position approximately corresponding to the center of the elastic vibrating support elements 3.
  • This pivot point has been conveniently designated in FIG. 6 by reference character and will be also seen to be located above the horizontal plane containing the body of the base plate 4. Owing to this arrangement the effective width of the throughpassage opening or slot 5 remains substantially constant throughout the oscillatory up and down movement of the base plate 4, this movement being substantially in the direction of discharge of the strewable material from the container housing 1 through the slot 5.
  • the inventive strewing apparatus depicted herein by way of example also possesses a suitable oscillating or vibration drive mechanism, to be considered in detail shortly, and which is arranged behind the rear wall la.
  • This vibrational or oscillating drive mechanism serves to place the base plate 4 into oscillatory or vibrational movement, by means of which the marginal edge of this base plate 4 which is situated at the region of the throughpassage opening 5 is primarily moved up and down, the upward movement, at least at the start thereof, occurring in jerky-like fashion.
  • this material particle A, as well as the other material particles which are located in the pile of material on or around the base plate 4 are periodically subjected, at short time intervals, to a movement component R which can be resolved into an upward or vertical component Y and a horizontal component X directed towards the throughpassage slot 5.
  • the vertical component Y serves to upwardly throw the material particle A, in other words for loosening the strewable material, while the horizontal component X serves to convey the material particle towards the throughpassage slot 5.
  • Both of these components X and Y come into existence owing to the fact that the pivot point 100 of the base plate 4 is located behind the rear wall In above the horizontal plane containing this base plate 4.
  • the oscillatory drive mechanism will be seen to embody as its primary element a cam disc 8 which can be placed into continuous rotation by means of a suitable electric motor drive.
  • the driven cam disc 8 acts upon a feeler element 9 which is rigidly connected with the base plate 4.
  • the electric motor drive will be understood to embody a motor transmission block 10, the housing of which is secured to a plate member 11 which, in turn, is pivotably mounted upon a shaft member 13 through the agency of a sleeve member 12 secured to such plate member.
  • the opposed ends of the shaft member 13 are fixedly seated in the side walls lb and 1c of the container structure considered above.
  • a bearing sleeve member is secured to the plate member 11 coaxially with respect to the output shaft 14 of the motor transmission block 10, a shaft stub 16 being rotatably and non-displaceably mounted within such bearing sleeve member 15 by means of the roller bearing 15a.
  • the shaft stub 16 includes a square portion upon which there is detachably secured by means of the screw 17, or other appropriate fastening expedient, the cam disc 8.
  • the illustrated cam disc 8 will be seen to be of the type incorporating a profile section 8a which gradually ascends practically along the entire periphery of such cam member and a steep dropping or descending cam portion 8b, so that during one revolution of the cam disc or plate 8 in the direction of the arrow 19 and by virtue of the tangentially extending feeler member 9 the latter together with the base plate 4 is subjected to an oscillatory or vibratory movement, the displacementtime characteristic of which possesses a substantially sawtooth-like character, as best seen by referring to FIG. 7.
  • the nature of this oscillation can further be varied by adjusting the oscillating position of the plate member 11 by means of the mechanism depicted in greater detail in FIG. 4.
  • a rod member 20 which is secured at its ends in the housing or container side walls 112 and 1c is equipped approximately at its middle region with a transversely extending bore 20a through which piercingly extends the shaft portion of an adjustment screw 21.
  • the threaded portion of this adjustment screw 21 engages with a threaded bore 22a of a pin member 22 which is secured to the lower extension of the plate member 11.
  • a helical spring 23 subjected to compression is placed between the rod member 20 and the pin member 22, as shown.
  • the screw member 21 By actuating the just-described adjustment mechanism, in other words the screw member 21, it is possible to vary the vibration or oscillation amplitude of the feeler element 9 and the base plate 4 in accommodation to the characteristics or properties of the material to be strewn, among other things, the grain size of this material.
  • FIG. 5 there is provided a rod member 24 which is fixedly seated at its ends in the side walls lb and 1c of the container structure.
  • This rod member 24 likewise possesses a transverse bore which is pierced by the shaft portion of an adjustment screw 25, the threaded portion of which engages in a threaded bore of a pin member 27.
  • the pin member 27 is mounted in a shoulder of the front wall M.
  • a spring member 26 is placed between this pin member 27 and the rod member 24.
  • the cam disc 8 which is scanned by the feeler element 9 rigidly connected with the base plate 4, possesses at least one steep descending cam portion 8b.
  • the rigid unit composed of the feeler element 9 and the base plate 4 is slowly" rocked or pivoted in the clockwise direction until base plate 4 has assumed approximately the position shown in phantom lines in FIG. 6.
