Abstract
A product sizing apparatus for removing undersized pieces of product from a product stream includes a frame extending along a longitudinal axis and having an input end and an output end and an endless web mounted about a drive shaft and a take-up shaft, both oriented along the longitudinal axis. The endless web moves transversely to the longitudinal axis to create turbulence in the product stream, and includes a plural-ity of pockets for capturing undersized pieces of product and for carrying the undersized pieces of product over the end of the frame where they may be deposited into a receptacle or other conveyor. The properly sized product moves through the trough and is deposited in a separate conveyor at the output end of the frame.
Description
~ 2178888 PRODUCT SIZING APPARATUS
Backqround of the Invention The following invention relates to a product sizing apparatus and in particular to a sizing apparatus for removing undersized pieces of product from a product stream.
A food product stream which has been cut or diced in order to size it for a particular purpose often includes undersized pieces which do not meet the required sizing specifications. It is, therefore, necessary to remove such pieces from the product stream without also removing the pieces that are properly sized. In the past, machines generically known as rotary separators or "reels" have been used for this purpose. A rotary sepa-rator is a cylindrical bin or drum through which product moves under the action of a vibratory motor. As the product moves, the drum rotates attempting to capture undersized pieces of product in square or rectangular pockets that have been inserted in cutouts in the surface of the drum. The undersized pieces are deposited on a conveyor shielded from the product below by deflector vanes that direct the undersized pieces onto the conveyor. A machine of this type is manufactured by A. K. Robins Company of Baltimore, Maryland.
There are numerous drawbacks to product sizing with a device of the type described above. The pockets inserted into cutouts in the drum are cylindrical with straight sides and an end cup. This causes the under-sized products to become wedged in the pockets and it isthen necessary to either insert brushes through slots in the pockets to knock out the imbedded product or to use high pressure water to flush the pieces out. Addition-ally, separators of this type are massive, being usually on the order of ten feet in diameter and requiring substantial power in the way of motors, reduction gears, etc., to run properly. Additionally, such machines are -nonadjustable. There is only one setting defining the size distribution of the unwanted pieces and the only way to affect the size distribution is to substitute pockets of different sizes into cutouts in the cylindrical drum.
Summary of the Present Invention A low cost, compact and economical solution to the above-noted problems is provided by the present invention which is a device for removing undersized pieces of product from a product stream. The invention includes a frame having an input end and an output end with the frame being tilted along a longitudinal axis so that the input end is vertically higher than the output end. A conveyor motor is attached to the frame and drives an endless web suspended over the frame so as to form a trough where the web moves transversely with respect to the longitudinal axis. The endless web includes a surface having pockets where the pockets are sized to capture undersized pieces of product as the product moves through the trough under the action of the conveyor motor which creates turbulence causing the product stream to flow from the input end to the output end.
In order to prevent wedging of the undersized product into the pockets, the pockets have continuously rounded inner surfaces with no straight sides. The end-less web may comprise interconnected articulated slats with the pockets formed therein. The pockets may have a substantially oval shape and the ovals may be aligned at an angle. This provides the most efficient use of the available length of the slat. Additionally, it has been discovered that better performance is obtained when the angular alignment of the ovals is reversed periodically over the length of the slat.
The endless web is suspended over a drive shaft, a take-up shaft and an idler shaft to create the trough. As the web is driven, pieces that are lodged in ` 2178888 the pockets in the trough portion travel up and over the frame where they drop out of the pockets into a collector placed below the frame for that purpose. The articulated slats form a substantially contiguous surface in the S trough and, therefore, the slats are slightly tapered in cross section so that the concave curve of the trough may be formed without pinching. The elongate slats forming the web may include chain links on either end thereof which fit sprockets on the drive shaft and the take-up shaft. The drive shaft in turn is coupled to a motor on the frame by way of a suitable chain and sprocket drive or a belt.
The sizing apparatus of the present invention may be adjusted in two different ways which will affect lS the accuracy and efficiency of the product sizing opera-tion. A take-up shaft which supports the endless web at the top of the frame is adjustable by moving the position of the shaft sideways along end rails of the frame. This adjustment determines the steepness of the web as it exits the trough, which in turn determines how much product is carried out of the product stream. For very accurate sizing the angle is made steep so that only product sizes which are well captured in the pockets will be extracted from the product stream. Making the trough angle flatter (by moving the shaft closer to the outside edge of the frame) will result in more product being extracted from the stream; however, adjusted this way properly sized product may also be extracted from the stream. The steepness of the angle, therefore, has a direct impact on the size distribution of the pieces of product removed from the product stream. A second adjustment is the angle of tilt of the frame along its longitudinal axis. The legs of-the frame may be provided with telescoping members which may be adjusted so that more or less tilt is provided. This will affect the speed at which the product stream moves through the - ` 2178~8 apparatus and also how much undersized product is removed at a desired rate of flow.
The foregoing and other objectives, features, and advantages of the invention will be more readily understood upon consideration of the following detailed description of the invention, taken in conjunction with the accompanying drawings.

Detailed Description of the Preferred Embodiment Referring to FIGS. 1 and 2 a product sizing apparatus 10 includes a frame 12 having an input end~l4 and an output end 16. The frame 12 includes front legs 18 and rear legs 20 and end rails 15 and 17. Either set of legs 18 or 20 may be made of telescoping members with alignment holes and pins or the like for adjusting the - 217~88 height of either the input end or the output end, thereby controlling the angle of tilt of the frame 12. A motor 22 is attached to the frame and includes a chain housing 24. A longitudinal axis (provided for orientation) is shown by the dash-dot line in FIG. 1.
The input end 14 of the apparatus 10 has a scoop number 26 which receives the output of a conveyor 28 which carries product. Undersized pieces of product are dropped into a receptacle 30 which sits below the frame 12 to one side thereof. Properly sized product drops from a chute 32 onto a conveyor 34 which removes the product for further processing.
An endless web 36 is comprised of a plurality of articulated slats 38 which are interconnected. Each of the articulated slats 38 includes a plurality of oval pockets 40 which serve as receptacles for undersized pieces of product as will be explained below. The end-less web is draped over a plurality of shafts (refer to FIG. 3) including a drive shaft 42, a take-up shaft 44 and an idler shaft 46. The endless web is allowed to hang from the shafts loosely thus forming a trough 37.
The drive shaft 42 is protected by a cover 48 connected to the frame 12.
The drive shaft 42 is driven by a chain 49 connected to a sprocket 50 on the output shaft 52 of the motor 22. The drive shaft 42 includes a sprocket 54 which engages chain links 56. Each of the articulated slats 38 is supported on one of the chain links 56 at each end of the frame. Additionally, there may be sprockets on the drive shaft 42 and the take-up shaft 44 interspersed along the length of the shafts to engage additional series of links (not shown) coupled to the undersides of the slats 38.
The drive shaft 42 is oriented lower than the take-up shaft 44. In order to keep product from falling transversely off of the side of the frame supporting the drive shaft, a guard deflector 58 is provided. At the 217~888 -other side of the frame, a product deflector 60 is provided to direct undersized pieces of product falling out of the endless web 36 into the receptacle 30. The operation of the invention with actual product 11 (for example, carrots) is shown in FIG. 3A wherein the move-ment of the endless web creates turbulence in the product stream thus causing it to tumble from the input end 14 of the frame 12 to the output end 16. Undersized pieces 13 of product 13 fall into the pockets 40 and are carried by the endless web 36 which moves transversely to the longi-tudinal axis of the frame and over one side of the frame.
As the articulated slats 38 turn over on the take-up shaft 44 towards an angle greater than 90 from vertical, the undersized pieces 13 of product 11 fall out of the pockets 40 and are deflected by the deflector 60 into the receptacle 30 below. The properly sized pieces of product 11 which cannot enter the pockets 40 fall back into the trough 37 formed by the endless web 36 and are eventually carried downstream and deposited in the conveyor 34.
Referring particularly to FIGS. 4, 4A and 4B, each articulated slat 38 is mounted on a link 56, at least at its distal ends. In each slat 38 pockets 40 are formed which are oval in shape and which are oriented at an angle to the long direction of the slat 38 which extends substantially along the longitudinal axis of the conveyor. As shown in FIG. 4B the pockets 40 have rounded inner surfaces 41. The rounding of the inner surfaces 41 ensures that undersized product does not become wedged in the pockets 40 but falls out easily as the web turns past horizontal as it moves around the take-up shaft 44.
Several adjustments are possible which greatly improve the efficiency and operation of the product sizer described herein. Referring to FIG. 5, the take-up shaft 44 is mounted in a bearing block 47. There is a bearing block 47 at each end of the separator and each bearing block 47 is mounted to respective end rails 15 and 17 by means of bolts 45. The bolts are inserted through a slot (not shown) in the end rails 15 and 17 so that the bearing block 47 may be moved back and forth along the side rails in the directions shown by the arrow in FIG. S. Moving the take-up shaft 44 in this way will affect the steepness of the trough 37 formed by the end-less web 36. The practical effect of this adjustment is that the size distribution, efficiency and accuracy of the separating operation will change. When the angle of the trough is steep, only the smallest pieces will be captured in the pockets 40 and deposited in the recep-tacle 30. This means that the distribution curve illus-trating the sizes of all pieces extracted from the lS product stream will be shifted toward the smaller end and will be a steeper curve. On the other hand, if the take-up shaft is moved toward the outside of the frame 12 resulting in a shallower trough angle, larger product pieces will be carried out of the product stream because the flatter angle means there is less friction. The distribution curve of the extracted pieces will shift toward the larger sizes and will be somewhat flatter.
Another adjustment that may be made is in the tilt of the frame. Either set of legs 18 or 20 may be made adjust-able such as with telescoping members (not shown). Thetilt of the frame 12 will affect the processing speed of the separator with a trade off in efficiency depending upon the desires of the user.
The terms and expressions which have been employed in the foregoing specification are used therein as terms of description and not of limitation, and there is no intention, in the use of such terms and expres-sions, of excluding equivalents-of the features shown and described or portions thereof, it being recognized that the scope of the invention is defined and limited only by the claims which follow.
