The invention relates to an arrangement for operating a chicken-hatching installation comprising trays accommodating the eggs to be hatched arranged on carriages located in several tiers one above the other, the said carriages being passed continuously through an incubating stove, aeration of the individual trays being carried out, during half of the path followed by the carriages, on one side thereof, and during the other half on the other side. The invention also relates to a hatching unit containing a mobile hatching carriage with moving conveyor-belts arranged thereon.
Description
The invention elates to an apparatus and method for operating a chicken-hatching installation.
Chicken-hatching installations are known. They normally operate with an incubating stove into which frames, loaded with eggs to be hatched, and which may be in the form of carriages, are introduced. All known machines have the disadvantage that they use very large amounts of power, have very high power losses, and are extremely labour-extensive. It is furthermore frequently necessary to work inside the incubating stove where temperatures may reach 37 to 39 C.
An apparatus of this kind is described in US. Patent No.
4,005,679. In this known apparatus the entire stove-chamber is heated uniformly and, in order to take into account an equalization of the exothermal and endothermal reactions of the eggs, each carriage is charged with eggs of the same hatching age, The hatching stove thus contains carriages in respect of which the hatching process varies in time. This apparatus is intended to provide satisfactory heat equalization between individual carriages. An apparatus of this kind - which has never proved itself in practice - does not provide adequate heat equalization between individual eggs. Within the relatively large stove it is also impossible to maintain adequate temperature equalization by means of heating and aerating devices.
Based upon this known apparatus, it is the purpose of the invention to improve thereon, so that the overall thermal economy within the actual incubating stove and the actual carriages is more uniform.
122770~3 To this end, it is proposed, according to the invention, that the guide-tracks be arranged on both sides of and around the aerating and heating device and that, within the individual carriages, the individual trays, or groups of trays, be charged with eggs at different stages of the hatching process.
Whereas, in the known device a carriage charged over its entire height with eggs of the same age, is fed into the installation and whereas this carriage, after going through the incubating process, i.e. after about 16 to 18 days, is taken as a whole from the installation and the incubated eggs are passed to the hatching unit the in-mention proposes that the carriage remain in the install-lion and that only individual trays be removed from the carriage and be fed to the said hatching unit, the empty spaces thus left being charged with fresh trays and the carriage continuing to circulate in the installation.
Thus a fundamentally different system is proposed by the invention achieving substantially more uniform heating of all of the eggs in a carriage and thus providing better treatment of each individual egg.
Apart from improving heat utilization, the in-stallation according to the invention does not require carriages to be removed from the incubating stove, in con-tryst to the device according to U. S. Patent No. 4,005,679.
Instead, the already heated carriage remains in the in-stallation and only fresh trays are placed in the hot carriage.
,, , According to one aspect of the present invention, there is provided in an arrangement for the operation of an egg incubation plant having a carriage conveyed on guides continually circulating through an incubation oven constructed in elongated fashion, equipped with ventilating and heating apparatus along with a loading and discharging arrangement said carriage carrying pivot ably journal Ed trestles accommodating the eras to be incubated, said trestles being disposed in several tiers over one another in the carriage, the improvement comprising guides disposed on both sides of said ventilating and heating apparatus, said guides aligned parallel to one another, in turn being joined with one another at the ends thereof by means of transverse conveyor sections and wherein said loading and discharging apparatus for said trestles is disposed at a location ahead of a head end of one of said guides, hydraulic pressure mechanisms, wherein conveying of said carriage through said incubation oven is executed in pass through travel such that a first carriage, at any given time, as seen in the direction of conveying, is pushed forward into the incubation oven by one carriage width by said hydraulic pressure mechanism and a heat insulated oven chamber within which is disposed said actual incubation oven, said actual incubation oven being separated from an inner space of the oven chamber by good heat conducting sheet metal or the like.
In the case of carriages equipped with fifteen trays arranged one above the other, only three trays i.e. three tiers, are charged with eggs of the same age. Thus, as the carriages circulate, it contains tiers of trays of five different ages. With this arrangement, the specific heat developed by the egg after about 8 days may be used to good effect in the entire carriage.
Since aerating and therefore heating of the eggs takes place on both sides of the trays, this not only ensures that each egg receives sufficient oxygen and heat, but also eggs are not dried out by "overwriting" of the eggs or tiers which has hitherto often been necessary, i.e. the humidity of the air and the eggs can be better controlled.
In basic contrast to existing methods, therefore, the method according to the invention provides for continuous passage of carriages through an incubating stove, individual carriages in individual tiers containing eggs of different ages.
This produces satisfactory heat-economy in the carriages and, throughout the entire incubation period, the said carriages are aerated not from one side only but from both sides, the mechanical cost of this being relatively low.
Moreover, the overall dimensions of the installation according to the invention are substantially smaller than those of existing installations for a given output.
The invention is also concerned with the design of the incubating-stove chamber itself and it proposes in order to accomplish its purpose, that the incubating stove itself consist of a heat-insulated stove chamber within which is located an actual continuous stove. The latter, i.e. the actual incubating stove, is separated from the interior of the inner chamber by material of good heat-conductivity, thus ensuring satisfactory temperature-equali~ation between the incubating stove and the stove chamber. This substantially simplifies the heat control of the incubating stove itself.
Examples of embodiments of the invention are ox-planned hereinafter in conjunction with the drawings attached hereto, wherein:
~27708 Fig 1 is a side elevation in partial cross-sec-lion of a stove installation according to the invention;
Fig. 2 is a diagrammatical plan view of the stove installation according to the invention;
Fig. 3 is a cross-section through the stove thus-treating the construction of the interior of the stove chamber.
Fig. 4 it a side elevation in partial cross-section of the hatching unit adjoining the incubating stove;
Fig. 5 is a plan view of the arrangement according to Fig. 4;
Fig. 6 is a cross-section through the stove chamber of the hatching unit; and Fix. 7 is a "shunting diagram" for the carriages.
In the said drawings, 1 indicates a stove chamber containing two parallel guide tracks 2,3 for carriages 4.
The said tracks may be in the form of simple rails along which the carriages can travel on wheels. Arranged at the end of parallel guide tracks 2,3 are transverse conveyor-sec-lions 5 and 6 by means of which carriages arriving on track 3 may be transferred to track 2 and carriages arriving on track 2 can be transferred to track 3. Located at the head end of track 3 and at the corresponding end of transverse conveyor-section 6 is a charging and discharging device 7 where the said carriages may be charged with eggs.
In the example of embodiment illustrated, each carriage holds fifteen trays 8 arranged one above the other.
The said trays are mounted to pivot about axes running at right angles to the direction of travel of the carriages along tracks 2 and 3.
~227708 The carriages are moved onto tracks 2 and 3 by hydraulic pushers 9,10, for example, for instance carriage 4 is moved by pusher 9 onto track 3. Pressure then applied to the following carriages pushes this carriage through the stove, along track 3, to transverse conveyor-section 5, over corresponding transverse conveyors 11 to the head-end ox track 2. The carriage is then moved by hydraulic pusher 10 onto track 2, through the stove until it reaches transverse conveyor section 6. A corresponding conveyor 12 then moves it to charging and discharging device 7.
Tracks 2 and 3 are arranged in parallel with each other but are spaced apart. Arranged in the free space thus formed between the tracks are aerating and heating devices 14. As shown in Fig. 3, hot air is passed by these devices through the trays in the carriages and is then exhausted.
The transfer of the carriages by transverse conveyor sections 5,6 ensures that each carriage is aerated and heated on each of its long sides as it passes through the stove. An appropriate supply of moisture can also be applied. It will be seen that, in contrast to existing equipment, the carriages can be adequately aerated and heated from all sides, using a relatively low air velocity, thus reducing the danger of the eggs drying out.
A heat recovery unit 15 may be provided above the actual stove chamber 1.
In the case of the method according to the invention, individual trays 8 in each carriage 4 are divided into tiers, three trays forming one tier. Fifteen trays therefore require five tier-units and these are charged with eggs of ~lfferent ages. AS compared with existing methods, this permits better utilization of the heating process within a carriage, with recovery of the resulting intrinsic heat arising during incubation of the eggs.
It may be gathered from Fig. 3 that the stove chamber consists of an insulated external housing 16. An-ranged in stove chamber 1 is the incubating stove 17. The latter is a continuous stove and is separated from the interior of the stove chamber by walls 18 which are made of a material having good heat conductivity. Thus, the interior of stove chamber 1, outside incubating stove 17, acts as a thermal buffer which facilitates and refines control of the thermal economy within incubating stove 17.
In the drawings, exhaust air is indicated by solid arrows, while flows of hot air are indicated by hollow arrows.
For the sake of clarity, some of the sensors, dirve-means, fans and conveyor lines are not shown in the drawings and are also not explained in greater detail.
Fig. 7 is a shunting diagram clarifying the method of operation of the installation according to the invention.
Individual carriages bear reference numerals 4,00 to 4,14. The two transverse conveyor-sections are marked 5 and 6. Arranged centrally between the two rows of carriages is the aerating and heating device 14. The charging and discharging location is marked 7.
In phase 1 of the operation, carriage 4,07 is in transverse conveyor-section 6. It is moved by conveyor 12, shown in Fig. 2, to the position shown in Fig. 7 as phase
Chicken-hatching installations are known. They normally operate with an incubating stove into which frames, loaded with eggs to be hatched, and which may be in the form of carriages, are introduced. All known machines have the disadvantage that they use very large amounts of power, have very high power losses, and are extremely labour-extensive.

Examples of embodiments of the invention are ox-planned hereinafter in conjunction with the drawings attached hereto, wherein:
~27708 Fig 1 is a side elevation in partial cross-sec-lion of a stove installation according to the invention;
Fig. 2 is a diagrammatical plan view of the stove installation according to the invention;

Fig. 5 is a plan view of the arrangement according to Fig. 4;
Fig. 6 is a cross-section through the stove chamber of the hatching unit; and Fix. 7 is a "shunting diagram" for the carriages.
In the said drawings, 1 indicates a stove chamber containing two parallel guide tracks 2,3 for carriages 4.
The said tracks may be in the form of simple rails along which the carriages can travel on wheels. Arranged at the end of parallel guide tracks 2,3 are transverse conveyor-sec-lions 5 and 6 by means of which carriages arriving on track 3 may be transferred to track 2 and carriages arriving on track 2 can be transferred to track 3. Located at the head end of track 3 and at the corresponding end of transverse conveyor-section 6 is a charging and discharging device 7 where the said carriages may be charged with eggs.
In the example of embodiment illustrated, each carriage holds fifteen trays 8 arranged one above the other.
The said trays are mounted to pivot about axes running at right angles to the direction of travel of the carriages along tracks 2 and 3.
~227708 The carriages are moved onto tracks 2 and 3 by hydraulic pushers 9,10, for example, for instance carriage 4 is moved by pusher 9 onto track 3. Pressure then applied to the following carriages pushes this carriage through the stove, along track 3, to transverse conveyor-section 5, over corresponding transverse conveyors 11 to the head-end ox track 2. The carriage is then moved by hydraulic pusher 10 onto track 2, through the stove until it reaches transverse conveyor section 6. A corresponding conveyor 12 then moves it to charging and discharging device 7.
Tracks 2 and 3 are arranged in parallel with each other but are spaced apart. Arranged in the free space thus formed between the tracks are aerating and heating devices 14. As shown in Fig. 3, hot air is passed by these devices through the trays in the carriages and is then exhausted.
The transfer of the carriages by transverse conveyor sections 5,6 ensures that each carriage is aerated and heated on each of its long sides as it passes through the stove. An appropriate supply of moisture can also be applied. It will be seen that, in contrast to existing equipment, the carriages can be adequately aerated and heated from all sides, using a relatively low air velocity, thus reducing the danger of the eggs drying out.
A heat recovery unit 15 may be provided above the actual stove chamber 1.
In the case of the method according to the invention, individual trays 8 in each carriage 4 are divided into tiers, three trays forming one tier. Fifteen trays therefore require five tier-units and these are charged with eggs of ~lfferent ages. AS compared with existing methods, this permits better utilization of the heating process within a carriage, with recovery of the resulting intrinsic heat arising during incubation of the eggs.
It may be gathered from Fig. 3 that the stove chamber consists of an insulated external housing 16. An-ranged in stove chamber 1 is the incubating stove 17. The latter is a continuous stove and is separated from the interior of the stove chamber by walls 18 which are made of a material having good heat conductivity. Thus, the interior of stove chamber 1, outside incubating stove 17, acts as a thermal buffer which facilitates and refines control of the thermal economy within incubating stove 17.
In the drawings, exhaust air is indicated by solid arrows, while flows of hot air are indicated by hollow arrows.
For the sake of clarity, some of the sensors, dirve-means, fans and conveyor lines are not shown in the drawings and are also not explained in greater detail.
Fig. 7 is a shunting diagram clarifying the method of operation of the installation according to the invention.
Individual carriages bear reference numerals 4,00 to 4,14. The two transverse conveyor-sections are marked 5 and 6. Arranged centrally between the two rows of carriages is the aerating and heating device 14. The charging and discharging location is marked 7.
In phase 1 of the operation, carriage 4,07 is in transverse conveyor-section 6. It is moved by conveyor 12, shown in Fig. 2, to the position shown in Fig. 7 as phase
Claims (2)
It may be gathered from the shunting diagram in Fig. 7 that the carriages remain at all times in the incubating stove, i.e. no carriage is removed from the stove. Fully incubated trays are removed from the carriages in the vicinity of charging and discharging device 7 and are re-placed by trays of fresh eggs. After this, the carriage continues to circulate.
Fig. 4 illustrates a so-called hatching unit which adjoins the incubating stove and bears the reference numeral 20. The said unit contains a hatching carriage 21 which is adapted to move back and forth within a stove chamber 22 in order to achieve satisfactory and uniform aerating and heating of the eggs and chicks. Carriage 21 comprises a plurality of conveyor belts 23 arranged one above the other and extending over the entire length of the carriage. The pre-incubated eggs are placed upon the said conveyor belts until the chicks are hatched in hatching carriage 21.
Arranged on each side of the hatching unit are fans 24 which provide air to maintain the desired temperature within the hatching carriage 21.
Here again, stove chamber 22 is in two parts, hatching stove 25 being arranged in its own chamber within stove chamber 22 and being separated therefrom by walls 26 made of a material having good heat conductivity.
Here again, a buffer action is obtained, as explained hereinbefore in connection with stove chamber 1 and Fig. 3.
The hatching unit arrangement illustrated in Figs.
4 to 6 also permits individual conveyor belts to be charged with eggs, in order to achieve satisfactory and economical thermal economy. Here again, a heat recovery unit 27 is shown above stove chamber 22. The use of conveyor belts 23 makes it easy to remove hatched chicks individually from each belt.
