Description

  The present invention relates to a loading / unloading apparatus for a live bird cage that is used when a live bird cage containing live poultry such as chickens is loaded and unloaded at a meat processing factory or the like.

  When transporting live birds from a poultry farm to a slaughterhouse, live bird cages are used. The raw birdcage is loaded onto a truck or the like and transported, and the raw birdcage is unloaded from the truck or the like at a slaughterhouse and transported to a slaughtering line or the like.

  In a normally used live bird cage, a lid is fixed to the upper side of the cage body by a locking claw, and an opening that can be opened and closed by a sliding door is formed in the lid. The raw bird cage is usually loaded in multiple stages on a truck, and when it arrives at the slaughterhouse, it is unloaded with the number of stages loaded on the truck.

  The live bird cage has vents around it, and is made of, for example, plastic, and can accommodate about 5 to 8 chickens. The weight of the raw bird cage is about 20-25 kg when 6 birds are included. In the slaughterhouse, the loaded live bird cages are placed one by one on the transport conveyor, and when the live bird cages are transported to the vicinity of the meat processing equipment by the transport conveyor, the worker pulls the sliding door to open the opening, The bird cages were taken out one by one through the opening and hung on the hangers of the meat processing equipment.

Patent Document 1 (Japanese Patent Laid-Open No. 61-136823) discloses the loading / unloading device. The structure of this loading / unloading apparatus is demonstrated based on FIGS. 12-14, the carrying-in part 1 which carries in the raw bird cage C is the roller type conveyor 2, the stopper 3 provided in the middle of this roller conveyor 2, and the positioning stopper provided in the terminal end of the roller conveyor 2 4, and a lowermost car detector 5 for detecting the raw birdcage C ₁ lowermost positioned in the load position P ₁ by the positioning stopper 4.

The roller conveyor 2 is for carrying in the live bird cages C _{1 to} C ₈ loaded in multiple stages that have been carried by a truck or the like. As shown in FIG. 12, the live bird cage C to be carried in is carried in, for example, eight-stage stacking of the raw bird cages C _{1 to} C ₈ , and is carried by the roller conveyor 2 to the carry-in position P ₁ . The stopper 3 is electrically connected to the control device 6, and operates based on an electrical signal from the lowest car detector 5 electrically connected to the control device 6. That is, when the lowermost car detector 5 is in live bird cage C ₁ at the lowest in the loading position P _1, issues a detection signal, and projects the stopper 3 on the roller conveyor 2, the car C ₁ which is next loaded the ~C ₈ and is adapted to wait.

On both side surfaces in the longitudinal direction of the live bird cage C, support concave portions 7 and 7 are formed. From the carry portion 1 is rotated chain 8,8 is provided as a rotating means for rotating the endless across the unloading unit, the roller chain 8, 8 between the loading position P ₁ and the carry-out position P ₂ Rotates in an endless manner. Car transport supports 9 and 9 are attached to the inner sides of the rotating chains 8 and 8 facing each other at regular intervals. The rotary chains 8 and 8 are rotated in the direction of the arrow a by the sprockets 10a to 10e, and the sprocket 10a is connected to the drive motor 11 through the chain 10f.

  The car transport supports 9, 9 attached to the inside of the rotary chains 8, 8 are provided with an attachment member 12 and a claw member 14 that can be rotated through a pin 13 to the attachment member 12 by a predetermined angle. The upper end portion of the attachment member 12 is attached to the pin 8a of the rotary chains 8 and 8 via the pin 15 so as to be rotatable in the direction of the arrow b. Further, an elongated guide hole 12a for passing the guide pin 14a and a through hole 12b for passing the pin 13 are formed in the intermediate portion of the mounting member 12. The guide hole 12a is provided along an arc shape centering on the through hole 12b.

  The claw member 14 has a claw 16 formed in the lower half, and an uppermost basket detection unit 17 provided in the upper part. At the upper end of the claw 16, a support surface 16 a that fits into the recess 7 of the live bird cage C and supports the live bird cage C is formed. Further, the uppermost basket detecting unit 17 is formed in a substantially semispherical shape, passes while sliding on the side of the loaded live birdcage C, and passes through the uppermost live birdcage C and comes out to the upper part only. The claw 16 can be fitted into the support recess 7 of the car C by falling inward in the direction of the arrow c due to its own weight around the center 13.

A pin 13 and a guide pin 14 a are attached to the claw member 14, and the pin 13 is passed through the through hole 12 b and is prevented from coming off by a stop member 18. The guide pin 14a is passed through the guide hole 12a. With this configuration, the claw members 14 and 14 can be rotated inward, that is, in the direction of the arrow c by a predetermined angle with respect to the mounting member 12 around the pin 13, that is, an angle at which the guide pin 14 a can move within the guide pin 14 a.
12, the unloading position P ₂ is is provided with conveyor (eg a roller conveyor) 19, carries out the raw birdcage C placed on the conveyor 19 to the next step.

In the loading / unloading apparatus having such a configuration, the cars C _{1 to} C ₈ loaded on the roller conveyor 2 by a predetermined number of stages are carried to the stopper 3 and wait there. When raw birdcage C in loading position P ₁ is eliminated, i.e., if the bottom car detector 5 does not detect the raw birdcage C at the bottom position of the load position P _1, the stopper 3 the control means 6 directs the rollers The bird cages C _{1 to} C ₈ descend from the conveyor surface of the conveyor 2 and are carried to the carry-in position P ₁ .

The rotary chains 8 and 8 are rotated in the direction of arrow a in FIG. 12 by the drive motor 11, but the uppermost cage detecting portions 17 of the cage transport supports 9 and 9 are in contact with both side surfaces of the live bird cages C _{1 to} C ₇ . during the pawl 16 is in a state away from the side surface of the raw birdcage _C 1 -C _7. When the uppermost basket detector 17 passes through the uppermost raw birdcage C _8, pawl 16 is out in the direction of the arrow c, it is fitted to the supporting concave portion 7 of the raw birdcage C _8.

Thus, the car transporting the support 9 and 9 can lift raw birdcage C _8. In this way, the uppermost raw birdcage C ₈ is lifted by the basket conveying support 9,9, transported to unloading position P _2. Thereafter, the live bird cages C _{1 to} C ₇ are also sent in the same manner, and lowered one by one to the carry-out position P ₂ . The raw bird cage C lowered on the conveyor 19 is sequentially carried to the next processing step.

JP-A 61-136823

  Since the loading / unloading device lifts the live bird cages C one by one, it has the advantage that the weight lifted by the cage transport supports 9 and 9 can be reduced. Further, since the rotating chains 8 and 8 are merely turned slowly, the moment of inertia does not work greatly. Further, during operation, the live bird cage C is suspended on both sides of the sprockets 10c, 10d, and 10e that are attached to the upper side of the rotary chains 8 and 8 and support the rotary chains 8 and 8. Since the live bird cages C suspended on both sides act as counterweights to cancel each other's weight of the counterpart live bird cage C, the driving force of the rotating chains 8 and 8 can be greatly reduced. .

  In addition, since the live bird cage C is lifted in order from the upper side, there is no restriction on the size of the live bird cage and it can be lifted even when different sizes of live bird cages are mixed. There is an advantage that the rotary door and the foreign matter are not caught on the bottom of the upper live bird cage.

  However, the cage transport supports 9 and 9 are tilted toward the live bird cage C, that is, in the direction of the arrow c in FIG. 14, and the claws 16 are fitted into the recesses 7 of the live bird cage C. Support the live bird cage C and lift the raw bird cage C, so that the inclination of the support surface 16a varies depending on the degree of inclination of the car transport support bodies 9 and 9. Therefore, depending on the inclination of the support surface 16a, the claw 16 may come off from the recess 7.

  On the other hand, if the degree of tilting of the car transport supports 9 and 9 is reduced, the stroke of sandwiching the live bird cage C from the left and right becomes larger, and it becomes impossible to handle the live bird cage C of different types and sizes, and the type of the live bird cage C to be used. There is a problem that is limited.

  In view of the problems of the prior art, the present invention is capable of simplifying the configuration of a live bird cage attachment attached to a rotating chain in a bird cage loading and unloading device, and fitting a live bird cage attachment and a live bird cage. It is an object to realize a loading / unloading device that does not cause a part to deviate.

In order to achieve such an object, the loading and unloading device for a live bird cage of the present invention comprises
A carry-in part in which a storage space for receiving a plurality of live bird cages containing live poultry is loaded and one or more live bird carry-out attachments are attached and the live bird cage is directed from the carry-in part toward the carry-out part A loading / unloading device for a live bird cage, comprising: a transport loop that transports each one from a conveyor; and a conveyor that transports the live bird cages transported to the unloading unit to a processing step,
The live birdcage carry-out attachment includes a link mechanism that is attached to the transport loop and has a parallelogram shape in which the joints are rotatable with respect to each other, and the side of the live birdcage is located on one side of the link mechanism that faces the transport loop. And a guide roller that is in sliding contact with the hook and a hook that is engaged with the edge of the live bird cage when the guide roller does not slide on the side of the live bird cage,
The raw birdcage carry-out attachment is moved upward from below while the guide roller is slidably contacted with the side surface of the raw birdcage while one side facing the conveyance loop of the link mechanism is lifted upward in the horizontal direction at the carry-in part. Thus, the hooks are locked one by one from the upper raw bird cage one by one, and the raw bird cages are carried out to the carry-out portion.

  In the device according to the present invention, like the loading / unloading device disclosed in Patent Document 1, a plurality of live bird cages loaded into the carry-in portion are lifted one by one in order from the upper stage side by a live bird cage carry-out attachment attached to the transport loop. Sent to the unloading section. Then, with the side of the live bird cage carrying attachment having the above-described configuration facing the conveyance loop (hereinafter referred to as “face side”) lifted upward from the horizontal direction, the guide roller is slidably brought into contact with the side surface of the live bird cage. Move the birdcage carry-out attachment from below to above.

  In this way, when the raw birdcage carry-out attachment reaches the uppermost raw birdcage and the guide roller is no longer in sliding contact with the side surface of the raw birdcage, the facing side approaches the live birdcage side. At this time, since the hook attached to the facing side is locked to the edge of the live bird cage, the uppermost live bird cage can be lifted.

  In the apparatus of the present invention, the raw bird cages carried into the carry-in section are carried out one by one from the upper stage to the carry-out section one by one, so that the carrying weight can be reduced and the carrying speed of the carrying loop can be slowed down. The moment of inertia can be reduced. Further, since the live bird cages being transported in the carry-in section and the carry-out section act as counterweights, the weights of the counterpart live bird cages are offset from each other, so that the driving force of the transport loop can be greatly reduced. .

  Furthermore, since the live bird cage is lifted in order from the upper side, there is no restriction on the size of the live bird cage and it can be transported even when different sizes of live bird cages are mixed. There are advantages such as certain rotating doors and foreign objects not being caught on the bottom of the upper live birdcage.

Further, since the weight of the live bird cage is supported by a link connected below the facing side, it is only necessary to set the compression strength of the link to a strength that can support the weight of the live bird cage. Accordingly, the live birdcage carry-out attachment can be simplified.
Further, since the facing side constitutes a part of the parallelogram link mechanism, it always faces the vertical direction regardless of the position in the horizontal direction. For this reason, since the hook part attached to the facing side does not tilt, there is no possibility that the hook part comes off from the edge of the live bird cage.

  In the device of the present invention, preferably, if the stopper for preventing the facing side from descending below the horizontal direction is provided in the live bird cage attachment, the facing side is always directed upward from the horizontal direction. it can. Therefore, the live bird cage can be reliably conveyed by the live bird cage delivery attachment.

  In the apparatus of the present invention, preferably, the height of the conveyor surface in the carry-out portion of the transfer conveyor disposed in the carry-out portion is set above the height of the conveyor surface set in the processing step, and the transfer is performed. It is good to arrange so that the conveyor surface of a conveyor may become a downward gradient toward the conveyance direction downstream. Accordingly, the live bird cage can be transported to the next processing step by its own weight without providing a drive mechanism on the transport conveyor. For example, if a driven roller conveyor or the like is provided as a transport conveyor, the live bird cage can be transported by its own weight. Thereby, the mechanism of a conveyance conveyor can be simplified.

  Furthermore, by increasing the height of the conveyor surface in the carry-out section of the transfer conveyor disposed in the carry-out section, the auxiliary equipment such as the drive device of the transfer conveyor is positioned higher than the floor surface where the loading / unloading device is provided. Can be installed. For this reason, it is not necessary to dig deeper into the floor surface on which the loading / unloading device is provided, so that the restriction on the installation location of the loading / unloading device is eased as compared with the conventional case.

According to the device of the present invention, the live birdcage carry-out attachment includes a link mechanism that is attached to the transport loop and has a parallelogram shape in which each joint portion is rotatable with respect to each other, and one side of the link mechanism that faces the transport loop. A guide roller that slides in contact with the side of the live bird cage, and a hook that is engaged with the edge of the live bird cage when the guide roller does not slide on the side of the live bird cage.
The raw birdcage carry-out attachment is moved upward from below while the guide roller is slidably contacted with the side surface of the raw birdcage while one side facing the conveyance loop of the link mechanism is lifted upward in the horizontal direction at the carry-in part. Thus, it is possible to simplify the structure of the live birdcage carry-out attachment and to fix the raw birdcage to the carry-out unit by sequentially locking the hooks one by one from the upper-stage live birdcage. There is no possibility that the heel part may come off from the edge of the live bird cage while being transported by the live bird cage delivery attachment.

  Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings. However, the dimensions, materials, shapes, relative arrangements, and the like of the component parts described in this embodiment are not intended to limit the scope of the present invention to that unless otherwise specified.

1 to 3, the vicinity of the loading / unloading device 20 is an unloading place for a truck carrying a live bird cage, and a floor surface 21 around the unloading device 20 is connected to the platform of the unloading place. .

  FIG. 4 shows an example of a live bird cage C. The live bird cage C has a rectangular shape with a width of 500 mm, a length of 750 mm, and a height of 260 mm, for example, and a lifting recess 26 is provided on the side surface. On the upper four sides are formed convex edge portions 27 for locking a collar portion of a transport attachment, which will be described later, and on the upper surface are an opening 28 for taking in and out live birds such as chickens, and for opening and closing the opening 28 A hinge type lid 29 is attached. The lid 29 may be a sliding door type. In the poultry farm, the live bird cages C are loaded on the truck in a plurality of stages, for example, eight stages. And it is unloaded to this platform with the number of stages loaded on the truck in the slaughterhouse.

1 to 3, the housing 22 of the loading / unloading device 20 has a gate shape, and as shown in FIG. 3, the size is such that eight live bird cages C _{1 to} C ₈ can be passed vertically stacked. Having an inlet portion. Below the entrance of the loading / unloading device 20, a recess 21 a is provided on the floor 21, and a driven roller conveyor 31 having a conveyor surface having the same height as the floor 21 is disposed in the recess 21 a. Yes. A partition 23 that divides the inside of the housing 22 into a carry-in part 30 and a carry-out part 40 is provided upright at the center of the housing 22. In addition, a motor casing 24 that houses a drive motor (not shown) for driving a conveyance loop, which will be described later, is provided outside the housing 22.

Sprockets 32 to 35 are arranged inside the housing 22, and a loop-shaped transport chain 36 is wound around these sprockets. The position of the sprocket 35 can be moved by a tensioner 37, whereby the tightening degree of the transport chain 36 can be adjusted. As shown in FIG. 3, two sprockets 32 to 35 are provided on both sides of the live bird cages C _{1 to} C ₈ placed on the roller conveyor 31, and a pair is arranged on both sides of the live bird cages C _{1 to} C _8. The transport chain 36 is arranged.

  An output shaft 38 of a drive motor (not shown) disposed in the motor casing 24 is disposed in the partition 23 in the horizontal direction. A sprocket 39 is attached to the output shaft 38, and a chain 41 is wound around the output shaft 38 and the sprocket 39. The tightening degree of the chain 41 is adjusted by the guide roller 42. The unloading unit 40 is provided with a driven roller conveyor 43 that conveys the live bird cage C transferred to the unloading unit 40 to the processing step. The roller conveyor 43 is disposed at a position higher than the downstream end in the transport direction at the start end disposed in the carry-out unit 40 and is disposed so as to descend toward the transport direction.

  Four live bird cage carry-out attachments 50 are attached to the transport chain 36 at equal intervals. Hereinafter, the structure of the raw birdcage carry-out attachment 50 will be described with reference to FIGS. 5 to 7, a bearing bracket 52 is fixed inside the frame 51, and link members 53 and 54 are rotatably attached to the bracket 52. The other end of the link member 53 is rotatably attached to a bearing bracket 56 fixed to a support plate 55 located on the back side of the frame 51, and the other end of the link member 54 is fixed to the support plate 55. It is rotatably attached to a bracket 57 for the bearing.

  A boss 58 is fixed to the back surface of the support plate 55, and the support plate 55 is connected to the transport chain 36 via the boss 58. As shown in FIG. 7, a frame 59 for attaching the guide roller 61 is attached to the surface of the frame 51, and four guide rollers 61 are attached to the frame 59 so as to be capable of rotating two on each side. . On the frame 59 located below the guide roller 61, two hook parts 62 that are engaged with the convex edge part 27 of the live bird cage C are attached. The flange portion 63 is formed in an arc shape in cross section so that it is difficult to come off from the convex edge portion 27.

  The link members 53 and 54 together with the frame 51 and the support plate 55 constitute a link mechanism 60 that forms a parallelogram. Then, both end joint portions 53a, 53b, 54a and 54b of the link members 53 and 54 connected to the frame 51 or the support plate 55 rotate via the brackets 52, 56 and 57 with respect to the frame 51 and the support plate 55. It is free. In addition, a stopper 63 that is integrally attached to the link member 53 and forms a fixed angle with the link member 53 is rotatably attached to the joint portion 53a.

  When the link members 53 and 54 rotate downward about the joint portions 53a and 54a, the stopper 63 comes into contact with the support plate 55, so that the link members 53 and 54 are prevented from descending downward from 45 ° obliquely upward. Is blocked.

  In this way, the link members 53 and 54 are set so as to rotate in the range of 5 to 45 ° above from the horizontal direction. The transport chain 36 and the live bird cage carry-out attachment 50 are arranged on both sides of the live bird cage C. However, in FIG. 5, the left-side transport chain 36 and the live bird cage carry-out attachment 50 are not shown.

In this embodiment having such a configuration, an operation procedure of the loading / unloading device 20 will be described.
The live bird cages C _{1 to} C ₈ loaded and placed on the floor surface 21 near the loading / unloading device 20 are moved onto the roller conveyor 31 by workers. The roller conveyor 31 of the carry-in section 30 in the housing 22 is provided with a sensor 65 for detecting the presence or absence of a live bird cage C. The sensor 65 detects that there is no live bird cage C on the roller conveyor 31 of the carry-in section 30. Then, the worker sends the live bird cages C _{1 to} C ₈ onto the roller conveyor 31 of the carry-in unit 30.

When the sensor 65 detects that the live bird cages C _{1 to} C ₈ are placed on the roller conveyor 31 of the carry-in unit 30, a drive motor (not shown) installed in the motor casing 24 starts operating. The output of the drive motor drives the drive sprocket 32 via the output shaft 38 and the chain 41. As a result, the pair of transport chains 36 moves in the direction of arrow a.

  In FIG. 8A, when the chain 36 moves in the direction of arrow a, the live birdcage carry-out attachment 50 starts to rise. At this time, since the link members 53 and 54 can rotate within a range of 5 to 45 ° above the horizontal direction with respect to the frame 51, the guide roller 61 moves upward while sliding the side surface of the live bird cage C. To do. Then, while the guide roller 61 is in sliding contact with the side surface of the live bird cage C, the hook portion 62 is in an arrangement relationship that does not engage with the convex edge portion 27 of the live bird cage C.

Therefore, the hook 62 is not engaging with any of the tongue 27 of the raw birdcage C ₁ -C ₇ until the raw birdcage C the uppermost. Then, as shown in (c) of FIG. 8, when the raw birdcage unloading attachment 50 reaches the raw birdcage C ₃ at the uppermost stage, the guide roller 61 exceeds the tongue 27 of the uppermost raw birdcage C ₃ For the first time, the hook 62 is locked to the convex edge 27 of the uppermost live bird cage C3. In this way, raw birdcage unloading attachment 50 can be lifted raw birdcage C ₃ at the uppermost stage.

The live birdcage C ₃ lifted by the live birdcage carry-out attachment 50 is carried to the carry-out unit 40 and placed on a roller conveyor 43 provided in the carry-out unit 40. Raw birdcage C ₃ a roller conveyor 43 live bird cage unloading attachment 50 which is placed on the directly descends out hook 62 from the raw birdcage C, returns to the lower position of the loading unit 30 through the guide rollers 44. Then, the same operation as before is repeated. The roller conveyor 43 is provided with a sensor 66 for detecting the presence or absence of the live bird cage C. When the sensor 66 detects that there is no live bird cage C on the roller conveyor 43 of the carry-out unit 40, the live bird cage C is detected. The operation of transferring the slag to the carry-out unit 40 is started.

In this manner, the raw bird cages C _{1 to} C ₈ sent to the carry-in unit 30 can be sequentially carried out to the carry-out unit 40 one by one from the upper stage side. As shown in FIG. 9, a pair of plate-shaped inclined guide 67 over the side of raw birdcage C ₁ of lowermost position of the carry section 30 is provided from the roller conveyor 43 of the unloading unit 40. Inclined guide 67 includes an inclined portion 67a which is arranged diverging from both sides downward conveyor 43, guide horizontally to positions on both sides of the live bird cage C ₁ lowermost of the carry section 30 continues to the said inclined portion And a horizontal portion 67b.

  The live birdcage carry-out attachment 50 in which the live birdcage C is placed on the roller conveyor 43 by the carry-out unit 40 moves along the inclined guide 67 in the direction of the arrow d. That is, as the live bird cage attachment 50 moves down, it moves so as to spread along the inclined portion 67a of the inclined guide 67. Thereafter, the transport chain 36 reaches the lowermost end, and the live bird cage attachment 50 starts moving horizontally. However, since the horizontal portion 67b of the inclined guide 67 is installed in parallel with the travel path of the transport chain 36, the guide roller 61 of the live bird cage unloading attachment 50 moves to a position below the carry-in portion 30 while contacting the horizontal portion 67b. .

  Thus, by providing the inclined guide 67, the live birdcage carry-out attachment 50 can move smoothly from the carry-out unit 40 to the carry-in unit 30 without being caught by foreign matter such as a frame.

  According to this embodiment, the live bird cages C loaded in the carry-in unit 30 are lifted one by one by the live birdcage carry-out attachment 50 and transferred to the carry-out unit 40, so that the weight of one or more live bird cages is lifted. There is no need. Therefore, the strength of the housing 22 of the loading / unloading device 20 and other strengths can be reduced, and the driving force for driving the transport chain 36 can be reduced.

  Further, with the live bird cage attachment 50 as a fulcrum, the live bird cage C lifted by the carry-in unit 30 and the live bird cage C transferred to the carry-out unit 40 act as counterweights to offset each other's weight. Further, the driving force required by the transport chain 36 can be further reduced.

  Further, since the live bird cage C is lifted in order from the upper side, there is no restriction on the size of the live bird cage C, and even when the different sizes of live bird cages C are mixed, it can be transported and The rotary door on the top of the birdcage and foreign objects are not caught on the bottom of the upper live birdcage C.

Further, the guide roller 61 and the flange portion 62 are attached to the transport chain 36 via a link mechanism 60 having a parallelogram shape, and the link members 53 and 54 are always above the horizontal direction and are supported by the stopper 63 with respect to the support plate 55. The angle of 5 to 45 ° is maintained. Accordingly, as shown in FIG. 10, at an angle alpha = 5 to 45 ° with respect to always vertically raw birdcage C, it bears the raw birdcage C in the direction of F _2. Therefore, since one link member 54 of the pair of live bird cage carry-out attachments 50 and the support bracket 56 support W / 2 of the dead weight W of the raw bird cage C, the configuration can be simplified. In FIG. 10, the stopper 63 is not shown.

  In addition, since the frame 51 forming one side of the parallelogram is always oriented in the vertical direction, the hook 62 attached to the frame 51 does not tilt, and therefore the hook 62 is the convex edge 27 of the live bird cage C. There is no risk of disengagement.

  Furthermore, as shown in FIG. 11, the roller conveyor 43 provided in the carry-out section 40 is led down to the suspension line 70 which is the next processing step. Then, the live bird cage C on the roller conveyor 43 is conveyed toward the suspension line 70 in the direction of arrow e. In the suspension line 70, a large number of hangers 72 are mounted on the transport chain 71, and the worker w takes out the live birds L one by one from the live bird cage C and hangs them on the hangers 72.

  In the present embodiment, the roller conveyor 43 is provided with a high conveyor surface at the carry-out unit 40 of the loading / unloading device 20 and the conveyor surface is inclined downward toward the suspension line 70. The live bird cage C can be supplied to the suspension line 70 by its own weight. Therefore, since it is not necessary to provide a driving device for the roller conveyor 43, the configuration of the roller conveyor 43 can be simplified and the cost can be reduced.

  Moreover, since the conveyor surface of the roller conveyor 43 in the carrying-out part 40 is provided high and the driving device for the roller conveyor 43 is unnecessary, the driving device for the roller conveyor 43 is provided on the floor surface 21 on which the unloading device 20 is installed. It is possible to eliminate the concave portion.
