  • This invention relates to a hydrau ⁇ lic line switcher and more particularly to a hydraulic line switcher with an optional automatic plug detection system for use with a hydraulic food cutting system having two or more hydraulic food cutting blade assemblies.
  • the potatoes are dropped into a tank filled with water and then pumped through conduit into an alignment chute or tube wherein the pota ⁇ toes are aligned and accelerated to high speed before impinging upon a fixed array of cutter blades where the potato is cut into a plurality of smaller pieces.
  • FIG. 1 The basic configuration of a prior art system, with the present invention added in, is shown in schematic format in Fig. 1.
  • One of the main components of a prior art hydraulic cutting apparatus for use in cutting potat ⁇ oes is a receiving tank into which peeled or unpeeled potatoes are dropped.
  • a food pump usually a single impeller centrifugal pump, is provided. It draws its suction from the receiving tank and pumps water and the suspended potatoes from the tank into an accelerating tube which functions as the converging portion of a venturi.
  • the accelerator tube is used to accelerate and align the potatoes immediately prior to impinging upon the station ⁇ ary knife blades of the cutter blade assembly.
  • Each whole potato impinging upon the knife blade assembly passes through the cutting blade array and is thereby cut into a plurality of food pieces, for example french fry pieces, which pass with the water into the second half of the venturi which is a diverging tube in which the water and the cut food pieces are decelerated back to a slower velocity.
  • the water and cut food pieces are then deposited onto a dewatering conveyer chain.
  • the water passes through the dewatering conveyor chain and is collected and recycled back to the receiving tank.
  • the cut food pieces remain on the conveyor chain and are carried off for further processing.
  • a plug such as this can take hours to clean out since it requires substantial disassembly of the machine and its attendant piping.
  • the study of what actually happens on a microscopic or cellular level when a food product, such as a potato, impinges upon the cutting blades of a cutter blade as ⁇ sembly is actually the study of hydrodynamics interplaying with the physics of the tearing and breaking of organic cellular structure.
  • the actual dynamics of the cutting cannot be accurately and completely mathemati ⁇ cally modeled.
  • Design of cutter blade assemblies and the establishment of cutter parameters, such as fluid flow, volumes and rates for food product feed, are generally empirically determined.
  • the present invention provides a means whereby cutter heads can be replaced on a much more frequent basis than that generally available to prior art systems. Accordingly, it is an object of the present invention to provide an apparatus which quickly senses the presence of the failure of a food product to pass completely through the cutter blade array so that the machine can either shut down, or, alternatively, automatically replace the cutter blade array assembly which is plugging with an unplugged, or clean, cutter head assembly.
  • Another object of the present invention is to provide a hydro-cutter assembly which has a mechanism whereby the cutter head assembly can be quickly removed from the line of fluid flow so that a mass of plugging food product can be flushed through the system, thus eliminating the need to shut the entire system down for manual removal of a plugging mass of food product.
  • a third object of the present invention is to provide a hydro-cutting assembly which has the capability of either periodically or selectively changing cutter blade arrays so as to ensure that dull cutter blade knives are replaced prior to deterioration of the quality of the cut food product being processed.
  • a hydraulic line switcher which enables the selective switching of the discharge of a suspension of fluid and food product from a hydraulic food pump into one of a number of discharge lines which are directly coupled to associated cutter blade assemblies. Switching can be accomplished either automatically or in a manual mode. Automatic control is used in cases where the initiation of a partial system plug up is detected, or manually for purposes of routine maintenance and cleaning.

  • slide coupler provides an adjustment means for compen ⁇ sating for varying lengths of the flexible tube and also for the compression of the flexible tube which occurs during the angular movement of the tube from between its full extension at one side to full extension at a second position.
  • a slide valve assembly which has a slide plate interfitting between an upstream cam plate and a downstream discharge plate. This slide plate is provided with a fluid orifice and can be positioned to direct fluid flow through the flexible tube and slide valve coupling into one of a plurality of discharge ports formed in the downstream discharge plate.
  • Means for moving the slide plate from alignment with one discharge orifice to another is provided by means of a dual action air cylinder mechanically connected to the slide plate by means of a lever which is itself pivoted to provide a mechanical advantage to increase the speed at which the slide plate can be moved from one position to another.
  • the dual action air cylinder is sized and powered to generate between 550 to 1100 pounds of shear force when moving the slide plate and also to provide a shifting of the slide plate from one discharge port to another within approximately 250 milliseconds, so as to shear any food product caught between the slide plate and either the cam plate or the discharge plate during movement, and also to preclude the initiation of a system blockage caused by a blockage of fluid flow and the queuing of food products against it in sufficient numbers to cause a system blockage.
  • a pressure sensing transducer is provided, to sense system over pressures in the hydraulic portion of the hydraulic cutting system. In the case of the preferred embodiment, it is located in the discharge line downstream from the hydraulic food pump. A normal band of system over pressures induced by food products impinging upon a fixed array of cutter blades within a cutter blade as ⁇ sembly, is determined, and a system over pressure set point, which is indicative of the initiation of a system plug up, is established, to actuate an automatic switching from one discharge line to another.

  • potatoes are flowing in the water and impacting upon the blades at the rate of 8.8 potatoes per second at a 20,000 pound per hour cutting rate, and at an average of 15.4 potatoes per second for a cutting rate of 35,000 pounds per hour. Also, it has been empirically determined that it only takes between three "to five pota ⁇ toes impacted against each other to form a blockage suf ⁇ ficient to plug the line.
  • 8.8 potatoes per second translates to one potato passing through hole 94 slide plate 78 every 110 milliseconds. At 15.4 potatoes per second, the frequency is reduced to one potato every sixty milliseconds. Given the fact that three or four potatoes impacted together will block the line, this means that slide plate 78 must not present a sufficient blockage to hold potatoes in place for longer than 200 to 300 milliseconds. Additionally, at the rate of 8.8 potatoes per second, assuming the potatoes are six inches long and the velocity is forty feet per second, there is at least a 10% chance that slide plate 78 will encounter or impact laterally against a potato as the slide plate is slid from one position to the other. For that reason, slide plates 78 must be capable of shearing a food product as it is repositioned.
  • the ram In practice it has been found that (at least in the case of potatoes) the ram must be capable of generating at least 200 pounds of force in order to move slide plate 78 quickly enough and with sufficient force to shear a food product caught between it and either front plate 80 or cam plate 82. In practice it has been found that if slide plate 78 can be repositioned in less than 250 milliseconds, plugging, while still possible, becomes more unlikely.
  • double action air cylinder 94 is provided and is operated in the range of 100 - 200 pounds per square inch and is capable of generating 550 - 1,100 pounds of shear force when acti ⁇ vated for movement of slide plate 78.

  • Slide plate lever 104 provides a mechanical advantage, in that its pivot point 106 is displaced up toward the pivotal connection between slide plate lever 104 and piston shaft attachment bracket 102, thus shortening the throw of piston shaft 98 to effect the desired lateral shift in slide plate 78.
  • Slide plate lever 104 is attached to slide plate 78 by means of extension post 100, which interfits within elongated lever slot 116 to provide a slidable linkage which compensates for the angular displacement of slide plate lever 104 about pivot point 106 relative to the lateral displacement of piston attachment bracket 102 during operation.
  • the mechanical advantage gained from slide plate lever 104 is used to enhance the speed that which slide plate 78 is shifted from one position to another.
  • a second embodiment of the present invention incorporates the same slide valve assembly and actuation mechanisms, but it differs in how cradle 52 is supported. Instead of a cradle cam being slidably sup- ported by traveler car assemblies 56, swing arm 224 at ⁇ tached to swing arm hinge pin 226 is provided. In this embodiment, the angular displacement of cradle 52 also closely matches the actual angular displacement of flexible tube 50 in operation.
  • this arrangement with the addition of a hinge, not shown, between swing arm 224 and swing arm hinge pin 226 allowing for vertical motion, and the addition of a second cylinder attached in some fashion to either swing arm 226 or cradle 52, would easily provide vertical adjustment capabilities which would enable the use of different arrays of discharge ports either radial, or vertically, thus allowing for movement of slide plate 78 in both vertical and transverse orientations so that different arrays and discharge ports could be used.

And used in conjunction with the sensors of my prior patent application Serial No. 08/019,581 filed February 18, 1993, to automatically switch the supply of whole food product and fluid from one cutting blade assembly to another upon the detection of the initiation of a system blockage.

However, in this preferred embodiment, only a single pressure sensing transducer 40 is provided, and in practice, it has been found to work satisfactorily. Under normal operating conditions, as each potato impinges upon, is cut into pieces, and passes through the cutter blade assembly, it will generate a pressure transient. These pressure transients can be empirically measured, and a range of normal pressure transients can be established.
  • pressure sensing transducer 40 is installed in the hydraulic portion of the hydraulic cut ⁇ ting system. In this case, in the discharge line 18 from pump 16.
