Description

egg collector

technical field

The present invention relates to an egg collector for use in chicken raising facilities.

Background technique

In a poultry farming facility that raises a large number of chickens and produces eggs, a row of cages in which a plurality of cages are continuously installed in the horizontal direction is stacked in multiple layers, and an egg collector is installed adjacent to the multilayer cage structure. The egg collector is a device that collects and collects eggs from a plurality of return conveyors arranged along each row of cages and collects eggs, and loads the eggs on the transfer conveyor that transfers the eggs to be washed. , Packaging downstream processing sites.

In the egg collector, a plurality of loading parts are fixed at a certain interval between a pair of endless chains, and each endless chain is wound on a pair of sprockets separated up and down. In the egg collector, a pair of endless chains circulates, and the loading part is conveyed in the vertical direction, and eggs are rolled out toward the transfer conveyor during this process.

Among chicken raising facilities equipped with such facilities, some facilities include a plurality of downstream processing plants, and there is a need to switch the transfer destination of eggs to any one of the plurality of downstream processing plants. For example, where each row of cages houses different types of chickens, different types of eggs are packaged in different downstream processing yards. Or, for maintenance of one of the downstream processing plants, it is desired to transfer the eggs to other downstream processing plants. In such a case, it would be more convenient if transfer conveyors could be respectively installed toward a plurality of downstream processing sites, and the conveyor at the destination of eggs rolled out from the egg collector could be switched to any one of the plurality of transfer conveyors. .

Therefore, the present applicant has conventionally proposed an egg collector capable of switching the transfer conveyor from which eggs are rolled out to any one of a plurality of transfer conveyors (see Patent Documents 1 and 2). In these proposals, a plurality of transfer conveyors are adjacent to the egg collector in a vertically isolated state. In addition, the egg collector moves a pair of roll-out sprockets respectively engaged with endless chains in the horizontal direction at positions corresponding to the plurality of transfer conveyors to approach the transfer conveyor of the roll-out destination. Along with this, since a part of the track of a pair of endless chains inclines with respect to a vertical direction, and a mounting part inclines at this part, an egg rolls out toward this transfer conveyor.

In the above means, there is no disclosure of a specific mechanism for moving the pair of sprockets for rolling out in the horizontal direction. In the actual field, it is required to realize a mechanism capable of easily moving the roll-out sprocket in the horizontal direction with a small force.

Contents of the invention

The problem to be solved by the invention

Therefore, in view of the above-mentioned actual situation, the subject of the present invention is to provide an egg collector which is equipped with a pair of sprockets which are respectively engaged with a pair of endless chains circulating in the vertical direction and can easily move horizontally with a small force. The mechanism that moves in the direction.

Solution to the problem

In order to solve the above-mentioned problems, the egg collecting machine of the present invention

"has: a pair of endless chains circulating in the vertical direction; a plurality of loading parts supported between the pair of endless chains; The roll-out mechanism in which a part of the track of the endless chain is inclined relative to the vertical direction is characterized in that,

The roll-out mechanism has:

A pair of movable sprockets are connected by the rotating shaft to rotate integrally;

A pair of side walls are erected vertically from the installation surface, so that the pair of endless chains are located between the pair of side walls;

A pair of guide holes are respectively provided through one side of the side wall along the horizontal direction;

The operation lever includes: a pair of first arm parts, each of which is rotatably attached to one of the side walls around a first axis; said first arm;

A pair of second arms has one end side connected to the middle part of the first arm part so as to be rotatable about a second axis, and the other end side is connected to the rotation shaft part through the guide hole, and the a pair of second arms rotate around a third axis which is a central axis of the rotation shaft portion; and

A pair of guide sprockets is provided at least below the movable sprocket, and guides the track of the endless chain in a vertical direction. "

In the coupling mechanism having the above structure, when the first arm is rotated around the first shaft by the operation of the operating lever, the third shaft moves along the horizontal guide hole via the second arm connected to the first arm via the second shaft. . The third shaft is a central shaft of a pair of movable sprockets that are connected by the rotating shaft portion to rotate integrally. That is, the movable sprocket can be moved in the horizontal direction by operating the operating lever. In addition, since the movable sprocket meshes with the endless chain while moving in the horizontal direction, it moves while pushing the endless chain toward the end point of the movement. Thereby, between the lower guide sprocket and the movable sprocket, it is possible to incline the track of the endless chain which these engage with from a vertical direction.

This linkage mechanism can be regarded as a linkage mechanism using a second type of lever using the first shaft as a fulcrum, the point at which force is exerted on the operating lever as a force application point, and the second shaft as an action point. The length of the first arm, the distance between the first axis and the second axis in the first arm, the distance between the connecting position of the first arm and the connecting arm and the second axis, and the length of the connecting arm The degree of freedom of setting is high, and it is easy to make the point of action closer to the fulcrum than the point of force application. Therefore, the second arm can be easily rotated around the second axis with a small force, and the movable sprocket can be easily moved in the horizontal direction via the second arm.

In addition, in the first arm part, the "intermediate part" where the second shaft is provided does not refer to the central part of the first arm part, but refers to the area between the end part on the side of the first shaft and the end part on the opposite side. s position.

The egg collecting machine of the present invention, on the basis of the above-mentioned structure, can be formed as

"When the first arm portion is rotated about the first axis by pressing down the operation lever, the end of the guide hole on the side where the third axis moves is bent downward."

In this structure, the guide hole bends downward at the end portion where the third shaft moves to the maximum in the horizontal direction by pressing the operating lever. Therefore, by rotating the second arm around the second axis from this state, the end of the second arm on the third axis side can be dropped into the curved portion of the guide hole. Thereby, the interference of the curved portion of the guide hole and the second arm can prevent the third shaft from returning to the original direction along the horizontal portion of the guide hole, and the position of the movable sprocket can be fixed.

The egg collecting machine of the present invention, on the basis of the above-mentioned structure, can be formed as

"This egg collector further includes a chain stopper that advances and retreats relative to the endless chain, engages with the endless chain in a forward state, and releases the engagement in a backward state."

In this structure, the rotation of the endless chain can be prevented by advancing the chain stopper and meshing with the endless chain. Therefore, the endless chain does not move unintentionally, and the operation of moving the movable sprocket in the horizontal direction can be performed stably and with good workability.

The effect of the invention

As described above, according to the present invention, it is possible to provide an egg collector which is equipped with a pair of sprockets that are respectively engaged with a pair of endless chains circulating in the vertical direction and can easily move in the horizontal direction with a small force. mechanism.

Detailed ways

Hereinafter, the egg collector 1 which concerns on embodiment of this invention is demonstrated using drawing.

The chicken raising facility equipped with the egg collector 1 is a facility which raises many chickens and produces eggs. This poultry raising facility is equipped with the multilayer cage structure (illustration omitted) which laminated|stacked the row of cages in which several cages were continuously installed in the horizontal direction, and was formed in multiple layers. The egg collector 1 is provided adjacent to one end in the longitudinal direction of the multilayer cage structure, assuming that the direction in which the cage row extends is the longitudinal direction. When the poultry raising facility is provided with several multilayer cage structures, the egg collector 1 is provided for every multilayer cage structure.

In the egg collector 1 , a plurality of mounting parts 22 are fixed at regular intervals between a pair of endless chains 21 . Each endless chain 21 is wound around a pair of sprockets (illustration omitted) spaced up and down, and circulates in the vertical direction. That is, the egg collector 1 is provided with the two pairs of sprocket wheels spaced up and down as a pair.

The egg collector 1 is provided with the casing which supports rotatably two pairs of sprockets on which a pair of endless chains 21 are respectively wound. The housing also supports a drive mechanism (not shown) including a motor that rotationally drives the endless chain 21 . Although the detailed illustration of the housing is omitted, it includes a pair of side walls 31 standing vertically from the installation surface. A pair of endless chains 21 is arranged in the space between these side walls 31 . The endless chains 21 circulate along the faces of the side walls 31 respectively.

As shown in FIG. 6 , the mounting portion 22 includes a first rod 22 a and a second rod 22 b spanned between a pair of endless chains 21 , and a part of the egg E is passed between the first rod 22 a and the second rod 22 b. Set the egg E in the state where the space is exposed. More specifically, each mounting portion 22 has a pair of a combination of a bottom bar 22e and two long side bars 22f fixed to both ends of the bottom bar 22e and forming an isosceles triangle together with the bottom bar 22e. . By fixing the hem bars 22 e to the endless chain 21 , one of a pair of combinations is fixed to one of the endless chains 21 , and the other combination is fixed to the other side of the endless chain 21 . Furthermore, the first rod 22a connects respective one ends of the paired heel rods 22e to each other. The second rod 22b connects the vertices of the isosceles triangles in each combination to each other.

In the egg collector 1, a pair of endless chain 21 circulates, and the mounting part 22 moves to the vertical direction. On the other hand, in the multilayered cage structure, the collection conveyor is arranged horizontally for every row of cages. The transport path of the recovery conveyor extends horizontally along the row of protective cages, and transports the eggs produced by the chickens to the egg collector 1 . The loading unit 22 that moves along with the circulation of the pair of endless chains 21 receives eggs from one of the recovery conveyors in the middle of its upward movement, and conveys the eggs in a state where the eggs are placed.

A plurality of transfer conveyors 50 are adjacently provided on the egg collector 1 . A plurality of transfer conveyors 50 transfer the eggs to different downstream processing sites, and are installed adjacent to the egg collector 1 in a state in which the respective transfer surfaces are separated in the vertical direction. Here, since the loading unit 22 of this embodiment loads eggs when the endless chain 21 is raised, the lowermost transfer conveyor 50 is provided above the uppermost collection conveyor. In addition, when the loading unit is of a type that can place eggs both when the endless chain 21 is raised and when it is lowered, the transfer conveyor can be placed on the side opposite to the side adjacent to the recovery conveyor with respect to the egg collector. side adjacent.

Hereinafter, in the egg collector 1, the side adjacent to the transfer conveyor 50 is called "A side", and the opposite side is called "B side". In the egg collector 1 of this embodiment, a pair of endless chain 21 which circulates in a vertical direction is driven so that it may ascend on the A side.

The egg collector 1 is provided with the same number of roll-out mechanisms 10 at height positions corresponding to the plurality of transfer conveyors 50 . The roll-out mechanism 10 moves the movable sprocket 25 engaged with the endless chain 21 in the horizontal direction so as to approach the transfer conveyor 50 , and a part of the track of the endless chain 21 circulating in the vertical direction is inclined relative to the vertical direction.

The configuration of the roll-out mechanism 10 will be described mainly using FIGS. 1 and 2 . In addition to a pair of movable sprockets 25 , a roll-out mechanism 10 also includes an operating lever 11 , a pair of second arms 12 , and guide holes 35 respectively provided in a pair of side walls 31 . The operating lever 11 of the present embodiment is constituted by a pair of first arms 11A and one connecting arm 11B. Here, the first arm 11A corresponds to the "first arm part" of the present invention, and the connection arm 11B corresponds to the "connection arm part" of the present invention.

The first arms 11A are each attached to one side wall 31 so as to be rotatable about the first axis P1. Specifically, by passing a pin (not shown) through the hole 31a penetrating through the side wall 31 and the hole 11e penetrating one end side of the first arm 11A, the first axis P1 that is the axis of the pin is passed. turn.

The connecting arm 11B is an arm that connects the first arms 11A to each other so that the pair of first arms 11A integrally rotate around the first axis P1. The connecting arm 11B is formed by bending both sides of the elongated plate at right angles in the same direction, and the two bent portions 11g are respectively fixed to the ends of the first arm 11A opposite to the first axis P1. Specifically, the connecting arm 11B is fixed to the bolt by tightening nuts to bolts respectively passing through a plurality of hole portions provided in the bent portion 11g of the connecting arm 11B and a plurality of hole portions provided in the end portion of the first arm 11A. first arm 11A. In addition, in order to securely fix, the connection arm 11B and the first arm 11A may be welded. The operation lever 11 is formed by integrating the connecting arm 11B and the first arm 11A.

The intermediate portion 11h of the connecting arm 11B having bent portions 11g at both ends is a portion that is held by the operator. In order to prevent the intermediate portion 11h from interfering with the pair of side walls 31, in the connecting arm 11B, the axial direction of the bent portion 11g is inclined with respect to the direction in which the first arm 11A extends. The direction of inclination is the direction toward the A side.

In the operating lever 11, the length from the boundary of the bent portion 11g and the intermediate portion 11h to the second axis P2 is set to be much larger than the length from the first axis P1 to the second axis P2. Accordingly, when the operation lever 11 is considered as the second type of lever, the distance from the point of action to the point of application of force is set considerably longer than the distance from the fulcrum to the point of action.

The movable sprocket 25 has teeth of a pitch that meshes with the endless chain 21 . The respective central axes of the pair of movable sprockets 25 are connected by the rotating shaft portion 25p, and integrally rotate around the third axis P3 which is the central axis of the movable sprocket 25 and the rotating shaft portion 25p. A pair of movable sprockets 25 is arranged between a pair of side walls 31 . In addition, a plurality of flat auxiliary plates 25d radially protrude from the rotating shaft portion 25p. The plurality of auxiliary plates 25d are arranged at equal angular intervals with respect to the third axis P3. Here, the case where there are two auxiliary plates 25d is illustrated.

A pair of guide holes 35 are respectively penetrating through the side wall 31 at the same height, and extend the same length in the horizontal direction. The guide hole 35 of the present embodiment is bent downward at one end. What is bent is the end of the A side.

The pair of second arms 12 is connected to the first arm 11A at one end thereof so as to be rotatable about the second axis P2 . Specifically, by passing a pin (not shown) through a hole 12f penetrating one end side of the second arm 12 and a hole 11f penetrating the first arm 11A, the second arm 12 rotates around the second axis that is the axis of the pin. The two axes P2 rotate. Here, the position of the hole 11f is between the end of the first arm 11A on the side of the first axis P1 and the end on the opposite side, and here is the distance from the first axis P1 to the length of the first arm 11A. About halfway there.

Each second arm 12 is attached to the rotation shaft portion 25 p via the guide hole 35 on the end side opposite to the second shaft P2 . Specifically, in the second arm 12, a pin (not shown) penetrating through the hole 12P provided on the end side opposite to the second shaft P2 is passed through the guide hole 35, and then attached to the rotating shaft 25p. Ends. The pin rotates integrally with the rotating shaft portion 25p, but the second arm 12 is rotatable with respect to the pin. That is, the second arm 12 is rotatable about the third axis P3 at the end opposite to the second axis P2, and the movable sprocket 25 is rotatable about the third axis P3.

The respective first axes P1 of the pair of first arms 11A are located on the same line, and the respective second axes P2 are located on the same line. In addition, the first arm 11A and the second arm 12 are provided on the outer side of the side wall 31 (the side opposite to the side facing the other side wall 31 ).

In addition, when the first arm 11A is rotated about the first axis P1, the portion of the first arm 11A farther from the first axis P1 and the link arm 11B further away from the first axis P1 are rotated in a large angular range. Since the resistance becomes large when such a largely rotated portion comes into contact with the surface of the side wall 31 and slides, in order to prevent this, the first arm 11A is separated from the side wall 31 on the side opposite to the side of the first axis P1. The way is curved between a first axis P1 and a second axis P2. Corresponding to this, the second arm 12 is also bent halfway so that the side of the second axis P2 is farther away from the side wall 31 than the side of the third axis P3.

In addition, the roll-out mechanism 10 includes a guide sprocket 26 that meshes with the endless endless chain 21 and guides the track of the endless chain 21 in the vertical direction. At least one pair of guide sprockets 26 is provided for each roll-out mechanism 10, and is provided below the movable sprocket 25 (see FIG. 6 ).

Next, the operation of the roll-out mechanism 10 having the above-mentioned structure, the accompanying change of the track of the endless chain 21 , and the accompanying roll-out of eggs will be described mainly using FIGS. 3 and 6 . Since the operation of each of the plurality of roll-out mechanisms 10 is the same, one roll-out mechanism 10 will be described here.

First, in the state where the roll-out mechanism 10 is not operated, the third shaft P3 is located at the B-side end of the guide hole 35 (see FIG. 3( a )). In this state, the movable sprocket 25 is separated from the endless chain 21 whose track is in the vertical direction without meshing.

When the middle portion 11h of the link arm 11B is held and the operation lever 11 is tilted toward the A side, the first arm 11A integrated with the link arm 11B turns around the first axis P1. Since the second arm 12 is connected to the first arm 11A through the second axis P2 , such a force as turning about the first axis P1 also acts on the second arm 12 . However, the second arm 12 is connected to the rotation shaft portion 25 p of the movable sprocket 25 via the third shaft P3 , and the movement of the third shaft P3 is restricted by the guide hole 35 . Therefore, along with the rotation of the first arm 11A around the first axis P1, the second arm 12 rotates on one end side around the second axis P2 and on the other end side around the third axis P3, which is horizontal along the guide hole 35. move towards side A. Accordingly, the movable sprocket 25 around the third axis P3 moves toward the B side (see FIG. 3( b )).

When the operating lever 11 is further tilted to the A side, along with the further rotation of the first arm 11A around the first axis P1, the third axis P3 moves along with the second arm 12 that rotates around the second axis P2 and the third axis P3. The guide hole 35 moves, and reaches the end on the A side (see FIG. 3( c )). In the middle of this movement, the movable sprocket 25 meshes with the endless chain 21 whose track is in the vertical direction, and moves while pushing the endless chain 21 to the A side.

Since the guide hole 35 bends downward at the end on the A side, the third axis is pushed down while the second arm 12 is turned downward around the second axis P2 in a state where the third axis P3 has reached the end on the A side. P3, so that it falls into the curved part of the guide hole 35. Interference between the curved portion of the guide hole 35 and the second arm 12 acts as a stopper, preventing the third shaft P3 from returning to the B side, and fixing the position of the movable sprocket 25 (see FIG. 3( d )).

As shown in FIG. 6 , the track of the endless chain 21 ascending on the A side is in the vertical direction up to the guide sprocket 26 located below the movable sprocket 25 . When the track of the endless chain 21 is a vertical direction, the mounting part 22 holds the egg E stably like the mounting part 22 in the lower right of FIG. 6 . When the movable sprocket 25 is moved to the A side by the operation of the operation lever 11 , the track of the endless chain 21 is inclined toward the A side between the guide sprocket 26 and the movable sprocket 25 . As a result, the loaded eggs E are rolled out toward the transfer conveyor 50 due to the downward inclination of the loading portion 22 in this portion. The transfer conveyor 50 includes a guide plate 59 extending toward the egg collector 1 , and guides the eggs E rolled out from the loading unit 22 to the transfer surface of the transfer conveyor 50 .

Moreover, the auxiliary plate 25d protrudes from the rotating shaft part 25p, and rotates together with the movable sprocket 25. As shown in FIG. Therefore, even if there is an egg E placed unstable on the downwardly inclined mounting portion 22 and not rolled out, the rolling out of the egg E can be assisted by the rotating auxiliary plate 25d contacting the egg E from above. The number of such auxiliary plates 25 d is set to correspond to the number of mounting parts 22 passing between the guide sprocket 26 and the movable sprocket 25 during one rotation of the movable sprocket 25 . In addition, illustration of the roll-out mechanism 10 is omitted in FIG. 6 .

Next, when a plurality of transfer conveyors 50 are provided for every egg collector 1 , the operation of switching the transfer conveyor 50 which is the roll-out destination of eggs from the egg collector 1 will be described. Here, the case where three transfer conveyors 50 are provided adjacent to one egg collector 1 is illustrated using FIG. 4 . Three transfer conveyors 50 are vertically separated and installed. Moreover, the same number of roll-out mechanisms 10 are provided corresponding to each transfer conveyor 50 on the egg collector 1 . The roll-out mechanism 10 is provided so that the height of the guide hole 35 is slightly higher than the conveyance surface of the transfer conveyor 50 .

Moreover, the egg collector 1 is provided with the chain stopper 40 which advances and retreats with respect to the endless chain 21, and meshes with the endless chain 21 in the advanced state. As shown in FIGS. 4 and 6 , the chain stopper 40 includes a base 41 supported between the pair of side walls 31 and a slider 42 that slides on the base 41 . In FIG. 4, although the case where the chain stopper 40 is arrange|positioned below the transfer conveyor 50 of the lowest stage was shown in figure, it is not limited to this position.

A groove 41g for guiding sliding of the slider 42 in the horizontal direction is formed in the base portion 41 . The slider 42 has a plurality of teeth 43 aligned in the vertical direction at one end in the horizontal direction. These teeth 43 are arranged at intervals to mesh with the endless chain 21 . A plurality of horizontally long long holes 45 are formed through the sliding body 42 , and the same number of bolts 46 protrude from the base 41 corresponding to the positions of the long holes 45 . As a result, the slider 42 slides in the horizontal direction within the length of the elongated hole 45 in a state where each bolt 46 is inserted through the elongated hole 45 . If the nut 47 is fastened on the portion of the bolt 46 protruding from the surface of the slider 42 , the position of the slider 42 relative to the base 41 is fixed. A backing plate 48 is interposed between the nut 47 and the slider 42 . In the egg collector 1, in the state in which a pair of endless chain 21 circulates, as shown in FIG.5(a), the chain stopper 40 retreats beforehand.

As shown in FIG. 4( a), when the eggs are rolled out toward the lowermost transfer conveyor 50, when the egg roll-out destination is switched to another transfer conveyor 50, at first, the movement of the endless chain 21 is stopped. drive. At this time, as described using FIG. 3( d ), the lowermost roll-out mechanism 10 is in a state where the movable sprocket 25 is moved to the A side to the maximum and its position is fixed. On the other hand, the other two roll-out mechanisms 10 are in a state where the movable sprocket 25 has moved to the B side to the maximum as described using FIG. 3( a ).

In this state, the nut 47 and the backing plate 48 are removed from the bolt 46 of the chain stopper 40 , the slider 42 is advanced, and the teeth 43 are meshed with the endless chain 21 as shown in FIG. 5( b ). By fastening the nut 47 to the bolt 46 via the backing plate 48, as shown in FIG. 5(c), the position of the slider 42 engaged with the endless chain 21 is fixed. Thereby, rotation of the endless chain 21 is prevented.

Then, for the roll-out mechanism 10 on the lowermost floor, by pushing up the operating lever 11, the state of Fig. 3(c) and Fig. 3(b) is returned to the state of Fig. 3(a).

Next, the roll-out mechanism 10 corresponding to the height of the transfer conveyor 50 which is the new roll-out destination of eggs is operated. For example, when the transfer conveyor 50 in the middle stage is the roll-out destination, as shown in FIG. 4( b ), the roll-out mechanism 10 in the middle stage is operated to move the movable sprocket 25 to the A side. Since rotation of the endless chain 21 is prevented by the chain stopper 40 , the operation of engaging the endless chain 21 and moving the movable sprocket 25 in the horizontal direction can be stably performed with good workability.

As shown in FIG. 3( d ), after fixing the position of the movable sprocket 25 , the chain stopper 40 is retracted, and the meshing of the teeth 43 and the endless chain 21 is released. In this state, if the endless chain 21 is driven, eggs will be rolled out from the egg collector 1 to the transfer conveyor 50 in the middle stage. Similarly, when the uppermost transfer conveyor 50 is used as the roll-out destination of eggs, as shown in FIG. 4( c), the movable sprocket 25 is moved to the A side in the uppermost roll-out mechanism 10. .

In this way, when switching the transfer conveyor 50 of the roll-out destination of an egg, it operates in the following procedure.

(1) Stop driving the endless chain 21 .

(2) The chain stopper 40 is advanced to prevent the rotation of the endless chain 21 .

(3) The movable sprocket 25 is moved to the B side by the operation of the roll-out mechanism 10 corresponding to the transfer conveyor 50 which is the roll-out destination of eggs at the present moment.

(4) The movable sprocket 25 is moved to the A side by the operation of the roll-out mechanism 10 corresponding to the transfer conveyor 50 which is a new roll-out destination of eggs.

(5) The chain stopper 40 is retracted to drive the rotation of the endless chain 21 .

In addition, in FIGS. 4( a ) to 4 ( c ), the case where the guide sprocket 26 is provided below and above the movable sprocket 25 in one roll-out mechanism 10 is shown. The lower guide sprocket 26 is used to maintain the track of the ascending endless chain 21 in the vertical direction until it approaches the movable sprocket 25 in a state moving in the horizontal direction. The upper guide sprocket 26 is used to return the track of the endless chain 21 passing the movable sprocket 25 on an inclined track in the vertical direction. However, when the space|interval of the transfer conveyor belt 50 separated up and down is not large, the upper guide sprocket 26 can be omitted. This is because the guide sprocket 26 below the roll-out mechanism 10 on the upper stage side plays the same role as the guide sprocket 26 above the roll-out mechanism 10 on the lower stage side. In addition, in the case of an egg collector of the type that discharges eggs while the endless chain is rising, eggs will not be placed on the loading portion 22 after passing the uppermost movable sprocket 25, so even if the track of the endless chain 21 There is no problem in tilting the upper sprocket among the upper and lower sprockets that circulate the endless chain 21 .

As above, the present invention has been described with reference to preferred embodiments, but the present invention is not limited to the above-described embodiments, and various improvements and design changes are possible without departing from the gist of the present invention.

For example, in the said embodiment, the case where the roll-out mechanism 10 provided with the movable sprocket 25 is the same number as the several transfer conveyor 50, and was installed in the egg collector 1 corresponding to the height of the transfer conveyor 50 was illustrated. It is not limited to this, The egg collector of the structure which fixes the sprocket for inclining the track of the endless chain 21 without providing the movable sprocket 25 to the uppermost transfer conveyor 50 is also possible. This is because, in the case of an egg collector of the type that discharges eggs while the endless chain is rising, in any one of the roll-out mechanisms 10 corresponding to the transfer conveyor 50 on the lower floor side, the movable sprocket is not used. 25 in the case of moving in the horizontal direction is limited to the case where eggs are rolled out to the transfer conveyor 50 on the uppermost floor.

In addition, in the above, the case where the operation lever 11 is formed by integrating the two members of the first arm 11A and the connection arm 11B has been exemplified. The present invention is not limited thereto, and it is also possible to perform bending processing or the like on a metal plate material cut into a desired shape to form an operating lever having an integral structure originally.
