Definitions

• the present invention relates to an apparatus and method for automatically providing food to young poultry.
• Feeding is often done using feeding lines, including a pipe having thereon openings which are directed to special pans hanging from the pipe.
• the food is supplied to the tube from a hopper, and advances along the pipe using, for example, a screw conveyor (sometimes referred to as an Archimedes Screw or Auger) activated by a motor.
• a typical feeding line may comprise between a few and dozens of pans, and each shed may comprise any number of feeding lines. Each bird may have access to one or more of the pans.
• Some of the pans along a particular line, usually a single pan, are referred to as "control pans".
• a control pan has thereon a sensor for sensing the level of food in the control pan, which is assumed to be representative of the level of food in all pans along the line. When the level of food drops below a predetermined level, a control command is sent to the feeding line motor, which activates the screw conveyor, such that more food is pushed along the pipe and dispensed into the pans.
• the regular feeding pans are not always adequate for young poultry which are small and weak and usually cannot reach the food in the pans.
• the relatively high rims of these pans usually prevent access by the young poultry even if the pans are removed from the pipe and placed directly on the ground. Therefore, it is common to see poultry farmers feeding the chicks manually during their first days of life, by simply pouring food on low-rim or no-rim trays (sometimes referred to as "auxiliary pans") placed on the shed's floor. Most of the chicks will feed from the auxiliary pans, and usually only a minority, consisting of the stronger and larger chicks, may be able to reach the regular pans and feed from them.
• PCT Publication No. WO1999/013708 discloses a trough designed for feeding poultry such as chicks, chickens or other fowl.
• a capacitive feed level sensor is fitted on one or more of the feed devices according to the invention, which feed level sensor can serve to control the central feed installation or to give warning of undesirable situations.
• U.S. Patent No. 5,927,232 discloses a feeder which may be readily adjusted so as to dispense a relatively small quantity of feed into the feed pan of the feeder and to continuously replenish such feed so as to maintain a substantially constant amount of feed in the feed pan as the feed is consumed between cycles of the feed conveyor which deliver more feed to the feeder.
• the feeder may be selectively adjusted so as to substantially flood the feed pan with feed thereby to make it easier for young birds to see the feed within the feed pan.
• a sensor may be positioned within control unit. This sensor is responsive to the quantity of feed within control unit such that upon the control unit receiving a desired amount of feed, the sensor will generate a signal indicating that the control unit is substantially filled with feed. This control signal is then used to stop operation of the feed conveyor.
• the feed conveyor upon another signal being generated for starting operation of the feed conveyor (such other signal may, for example, be a timer or the same or another sensor located within the control unit sensing that the feed within the feeder has dropped below a predetermined level), the feed conveyor will again resume operation so as to convey fresh feed along feed conveyor and to refill each of the feeders along the feed conveyor.
• signal may, for example, be a timer or the same or another sensor located within the control unit sensing that the feed within the feeder has dropped below a predetermined level
• U.S. Patent No. 5,311,839 discloses a poultry feeder located at each of the feeding stations which allows young chicks to readily see and to have access to the feed in the feeder.
• the conveyor switch has a feed sensor located within feed drop tube so as to be responsive to the amount of feed in the drop tube. More particularly, feed sensor is movable within feed drop tube from a first or tube full position to a second or tube empty position for opening and closing switch in response to the amount of feed within the feed drop tube. It will be appreciated that with the feed tube filled with feed such that the feed within the drop tube serves as a feed reservoir for resupplying feed to feed pan as the birds consume feed from feed pan, the level of feed within feed drop tube will correspondingly drop.
• switch Upon the feed within the drop tube falling below a level which permits the switch arm to move fully to its second or tube empty position (shown in FIG. 21), switch is actuated to turn on the feed conveyor thereby to replenish the feed in the feeders and in the control unit. As feed is supplied to the control units, the feed will drop down through drop tube, fills feed pan, and backs up within the drop tube.
• U.S. Patent No. 6,050,220 discloses an improved poultry feeder which is constructed so that the lowest position of the feeder results in producing the highest feed level within the feeder so that the young birds can see the feed and are drawn to the feed within the feeder.
• the highest feed level within the feeder also permits young birds to crawl into and out of the feeder.
• a poultry feeder adapted to be supported by a horizontally extending feed distribution tube comprising a generally vertical drop tube adapted to be supported by and receive feed from the distribution tube, a feed pan disposed under said drop tube for receiving the feed and supported by said drop tube for vertical movement relative to said drop tube, a grill member surrounding said drop tube and connected to said feed pan, a vertically moveable flow control member disposed within said feed pan for establishing an adjustable level of feed within said pan and moveable vertically relative to said pan and said drop tube, a support actuator for said flow control member and connected to said drop tube, and said support actuator being operable to move said flow control member downwardly relative to said pan automatically in response to upward movement of said drop tube relative to said pan.
• U.S. Patent No. 2,800,106 discloses an automatic feeder for poultry. When the chicks are small the pan can be placed close to the floor and as the birds grow the pan can be raised accordingly. A switch is set to be operated by the clock so that all of the feed buckets are filled automatically through a predetermined period of the night.

• Fig. 1A and Fig. IB show a schematic illustration of a typical feeding line 100.
• Feeding line 100 comprises a container or a hopper 104 which is filled with poultry food such as barley, chick-peas, millet, wheat bran or any other suitable food, or a combination of several types of grains.
• Container 104 may be connected to or hung by wires 120 from an appropriate fixture.
• Container 104 is connected to a pipe 108 which may be made of metal, such as galvanized still, or of another rigid material.
• Pipe 108 is connected to a motor 112, which may activate a screw conveyor contained inside the pipe in order advance the poultry food from container 104 along pipe 108.
• Pipe 108 and motor 112 may be hung by wires 116, for example from the ceiling of the shed.
• An anti-perch cable 117 may be stretched above pipe 108, to prevent poultry from standing on the pipe itself.
• Motor 112 may receive control commands via an electrical cable (not shown) and/or wirelessly from a shed controller (not shown), which may be pre-programmed, receive control commands from an external source such as a food level sensor, manually activated and/or the like.
• the controller may be positioned, for example, inside the shed, whether in a control room built inside the shed or within the main space of the shed, next to one of the walls.
• the control room may also be located outside the shed, such as adjacent to one of its walls.
• the controller optionally controls and/or monitors multiple parameters in the shed, such as temperature, humidity, ventilation, light, water supply, food supply and/or the like.
• the poultry farmer may preset one or more of these parameters, and the controller may then control the necessary operations in the shed automatically.
• the parameters may be changed by the poultry farmer from time to time, as needed.
• the controller may include a computing unit having a processor, a random access memory (RAM) and a non-volatile memory.
• the controller may send and receive digital and/or analog signals.
• Pipe 108 has one or more openings (not shown), optionally in its bottom side.
• Each of feeding pans 124 is hung from pipe 108 using a connector 126, and aligned with one of the openings in the pipe, so that activation of the screw conveyor causes food to exit the opening and fall into the feeding pan.
• pans 124 may serve as a control pan having a sensor for sensing the food level in the control pan.
• a corresponding signal or control command may be sent via an electrical cable (not shown) to controller 104, so that motor 112 activates and fills pans 124.
• the signal or control command may be analog and/or digital.
• a pan 124 may have too high a rim, or may be too elevated from the floor for a few days old chick to see or reach the food. Therefore, one or more auxiliary pans, such as one auxiliary pan 128, may be provided.
• Auxiliary pan 128 may be accessibly lower than pan 124, may have lower rims and/or be positioned directly on the floor, so that the chicks can easily see and reach the food, or even step into the auxiliary pan.
• Auxiliary pan 128 receives the food from a corresponding opening in pipe 128 via a structure such as a cone 132. This structure may also be referred to as a "chick feeding apparatus". It is also possible to omit one or more of the auxiliary pans and dispense the food through cone 132 directly to the floor.
• Fig. IB shows feeding line 100 in which pans 124 and auxiliary pan 128 are filled with food. It can be seen that the lowest food grains in pans 124 are higher than those in auxiliary pan 128. This difference may be significant for newly-hatched chicks.
• auxiliary pan 128 is filled to capacity, some of the lower part of cone 132 may be sunk in food, as shown. The height of cone 132 may be such that its lower rim is suspended above auxiliary pan 128 or the floor, whichever is relevant. This allows food dispensed via cone 132 to spread sideways on auxiliary pan 128, around the cone.
• cone 132 gradually empties due to gravity, so that the food level inside it lowers, and the food is dispensed onto auxiliary pan 128. Eventually, when all food has been consumed from auxiliary pan 128, cone 132 becomes essentially empty.

• Cone 132 may be positioned above an auxiliary pan, such as auxiliary pan 128, or directly above the floor, as discussed above.
• the sensor is configured to sense the food level inside and/or in the vicinity of cone 132. When the sensor does not sense food in its vicinity, or otherwise senses that the level of food is below a predetermined threshold, it provides a control signal, which may be an analog and/or a digital signal, to the controller, for example via a cable, a wireless connection, or the like.

• the controller may then activate motor 112 for a predetermined duration, such as a few seconds or minutes, depending of one or more factors such as the height of the sensor in or on cone 132, the sensed food level, the chicks' age, the cone's volume, the volume and supply rate characteristics of pipe 108 and its internal screw, etc.
• the activation causes the screw conveyor to swivel and dispense food through cone 132, for example into auxiliary pan 128 or directly onto the floor.
• food will also be dispensed to them.

• the controller constantly receives the sensor's readings and determines when a certain reading (or multiple readings) exceeds a preset threshold and constitutes a meaningful "signal", based on which motor 112 is to be triggered.
• the controller includes a noise filtering functionality, in which it reacts to a signal from the sensor (whether a signal that food is present and/or that food is absent) only if multiple consecutive signals are consistent in the food present/absent indication. This may prevent a case where a momentary reading of the sensor causes the controller to prematurely or incorrectly trigger the dispensing or stopping the dispensing of food.
• the noise filtering functionality may enable an operator to set the aforementioned threshold for a meaningful signal, which threshold may be defined, for example, by time (e.g. a number of seconds).
• the controller includes a wear prevention functionality, intended to prevent wear and damage to motor 112 if hopper 104 becomes empty; if such a scenario occurs and a wear prevention functionality is not present, the controller may keep instructing the motor to operate, since the sensor will never indicate that sufficient food is present.
• the wear prevention functionality accordingly, stops motor 112 after a predetermined period of time, optionally set by the operator, if there is still no indication from the sensor that sufficient food has been dispensed. This implies that hopper 104 is likely empty. The period may be, for example, a few dozen seconds up to a few minutes, for example.
• the sensor may further provide an indication of its status, wherein the indication may comprise light, sound and or the like. This may enable the user to know if a current operation of the screw conveyor was triggered by the sensor or by the regular control pan.

It is explicitly intended that the term "cone”, as referred to herein, be interpreted as relating to a chick feeding apparatus of any other shape, not necessarily a cone; the term “cone” is used here for reasons of simplicity only.
• Cone 132 may be an assembly of tubes arranged and secured to one another in a telescope configuration.
• the telescopic assembly may include an upper tube 402 and a lower tube 404, the lower tube having a conical shape.

• Lower tube 404 may be mounted on upper tube 402, such that the lower tube can slide over the upper tube. This sliding enables adjustment of the total height of cone 132.
• the total height may affect, for example, the gap between cone 132 and the floor or the auxiliary pan, and/or make the cone suitable to sheds having pipes suspended in different heights.
• a fastening mechanism such as a pair of fasteners 408 and 408', may be provided on either upper tube 402 or lower tube 402, to secure their relative position. In other embodiments, however, a cone may have a fixed length with no telescopic capabilities.

• cone 132 may simply be rotated about the pipe, such that its upper 402 and lower 404 tubes point upwards (hereinafter "upright position"). Since the pipe does not have a hole in its opposite, upper surface, food will no longer exit the pipe at the cone when the screw conveyor is activated; the internal surface of upper part 420 of the cone will block the hole in the pipe's lower surface, thereby disabling the cone.
