Description

  The present invention relates to an automatic feeding device used for livestock breeding experiments.

  In conducting a test for raising livestock under predetermined breeding conditions, it is necessary to appropriately manage the conditions for feeding the livestock to be raised, particularly the amount and timing of feeding. Since feeding to the target livestock is performed day and night, and it is often long-term, it is desirable to reduce the burden on the feeding worker. Therefore, if feeding preparation is performed at an appropriate time, an automatic feeding facility is installed so that feeding is automatically performed for a certain period thereafter (for example, for one day). There have not been many examples of a unique automatic feeding apparatus as a test and breeding facility for livestock, but there is an example shown in Patent Document 1 regarding an apparatus for automatically feeding livestock in a livestock farm.

  In Patent Document 1, automatic identification tags are attached in advance to a large number of domestic animals to be reared, and the tags are read at the feeding place to identify the domestic animals that have entered the feeding place, and as feed for the identified domestic animals. A technique for automatically feeding programmed bait to a feeding place by a belt conveyor is disclosed. Such a technique can be applied as a facility in a large-scale permanent livestock facility that raises a large number of livestock, but the experiment costs such as test breeding are limited and must be implemented with very short preparations. In the case of temporary equipment for short-term use as an experimental facility, it is difficult to apply large-scale equipment using a conveyor from the viewpoint of cost and installation period. In the apparatus using the conveyor, a time delay occurs from the time when the feeding start command is issued until the feed transported by the conveyor reaches the feeding place, and the feeding timing is delayed. Therefore, it may be necessary to delay the next feeding timing due to the delay in feeding the feed by the conveyor, and there is a problem that the feeding cycle is restricted.

  A technique that can be applied to other automatic feeding devices is disclosed in Patent Document 2, for example. In this case, a plurality of containers, each having a storage container having a payout lid that can be opened and closed at the bottom, are preliminarily provided in the storage container (Patent Document 2 is a description of a fine powder handling apparatus, Is also a related technique), and the bottom lid is opened and the food is discharged to the feeding place. Patent Document 2 is to open the bottom lids of a plurality of storage containers at the same time, and cannot be applied to the need to pay out livestock feed stored in advance in the plurality of storage containers according to the set time as in the present invention.

As described above, the object of the present invention is to provide a device intended to enable automatic feeding in livestock breeding experiments, and an automatic feeding device that serves the purpose can be easily and quickly. It is required that it can be installed and that it can be easily installed and removed as a temporary facility, and that no special start-up adjustment by an expert is required. Therefore, it is essential that the apparatus has a small number of parts, is compact, and is simply configured. In addition, it is necessary to reduce the cost as an experimental device, and it is required to have a simple configuration, and there are cases in which a conventional technique using a conveyor cannot sufficiently cope.

  To provide a simple, compact, and inexpensive device that is optimal in structure, structure, and mechanism as an automatic feeding device used in livestock breeding tests.

  After preparing for feeding by putting food in multiple containers in advance, the lid provided on the bottom of the container is automatically opened at a preset time interval and automatically discharged to the feed supply location for livestock to be raised. By constructing a compact, low-cost device that integrates the function of feeding automatically, a device suitable for livestock breeding tests that solves the above problems can be realized. That is, a plurality of the containers (hereinafter referred to as “food storage containers” or simply “containers”) whose number is determined by a period during which the target livestock can be fed without human intervention and a feeding interval therebetween, and a bottom bottom surface of the food feeding container An openable / closable lid provided to cover the bottom of the container so that the food can be stored by closing the lid, or to open the lid to discharge the stored food to the bottom. The automatic opening and closing mechanism configured to open the bottom is integrally installed on the gantry, and it is a compact and simple configuration as an automatic feeding device for livestock breeding tests for the purpose of the present invention. This makes it possible to realize a low-cost device.

  The invention according to claim 1 is a plurality of bait storage containers, which are attached to the bottom surface of the containers with hinges, and are bottom plates that move up and down to close or open the bottom surface of the containers And the bottom cover is attached to the bottom cover by an elastic body so as to protrude from the periphery of the cover. When an external force is applied to the tip of the part protruding from the periphery of the cover, the rod-shaped member Is configured to move in a direction substantially parallel to the surface of the lid so that the protruding portion is retracted in the direction of the bottom lid periphery (hereinafter referred to as a lid stopper). In addition, an actuator is attached to the gantry so as to push the protruding portion of the lid stopper protruding to the periphery of the lid, and to move and retract in the direction of the bottom lid periphery. The rod-shaped member of the lid stopper is held in a position where a part of the longitudinal direction of the lid stopper protrudes from the peripheral edge of the bottom cover of the storage container by an elastic body, and external force is applied to the distal end of the protruding portion of the stopper to the elastic end. It opposes toward the periphery of a storage container bottom cover. Thus, the lid stopper projection is supported from below by the stopper holding material and the lid on the bottom surface of the container is held in a closed state, or the stopper projection is removed from the holding material and one side of the bottom lid (opposite the hinge mounting portion). Side) is dropped, the lid is opened, and the food stored in the food storage container can be released.

  In the first aspect of the present invention, as shown in FIG. 1, the plurality of bait storage containers are arranged on a gantry so that the tips of the protruding portions of the bottom surface lid stopper form a substantially horizontal straight line. Here, arranging the tips of the protrusions so as to form a substantially horizontal straight line means that the actuator that performs one linear motion pushes the bottom cover stopper protrusion of any of the plurality of food storage containers in the peripheral direction of the bottom cover, and The storage container is arranged so that the tip of the lid stopper protrusion is aligned within the range in which the lid stopper attached to the container can be released from the lid stopper holding material and the bottom surface of the corresponding storage container can be opened. The straight line should be level enough to feed the chute below the storage container.

  In FIG. 1, a lid stopper holding material is attached to a position that holds the bottom side of the lid stopper and holds the bottom lid in a state where the bottom surface of the storage container is closed. The holding member may be a member in which a common beam-like member that supports a plurality of bottom cover stoppers is attached to a gantry, or may be provided for each container. In any case, the holding material needs to be installed in such a size and positional relationship that it holds the lid stopper when the lid stopper is in a projecting state and is detached from the holding material when the stopper is pushed in a certain amount. As shown in FIG. 5, the linear actuator has a rod-like member (hereinafter referred to as a screw load) having a male screw that rotates around an axis by a driving means that rotates in the circumferential direction, and a member corresponding to the male screw-like rod-like member. A nut having a screw, the nut being freely movable in the axial direction of the screw rod, but a mechanism for suppressing rotation around the screw rod axis, for example, a guide rail in which the nut slides or a hole provided in the nut A rod-like member that passes through the rod and is attached in parallel with the rod, and the like are added, and the nut moves in the axial direction of the rod by rotating the screw rod. The nut is configured as a linear actuator having a laterally extending portion necessary for pushing the protruding portion of the bottom surface lid stopper to remove the lid stopper from the holding material.

  As shown in FIG. 1, one linear actuator is connected to a plurality of bait storage containers arranged on a gantry, and the movement direction of the actuator and the straight line formed by the tips of the lid stoppers of the plurality of storage containers are parallel to each other. When the protruding portion of the lid stopper comes into contact, the stopper is detached from the stopper holding mechanism and attached in such a positional relationship that the corresponding bottom surface of the storage container opens. Below the plurality of bait storage containers, a chute that receives bait discharged from any of the storage containers and discharges it to the outside is provided. The chute is an inclined plate material having a projected area that covers the lower side of a plurality of storage containers, and its end is usually connected to a livestock feed box. In the use of the apparatus shown in FIG. 1, as a preparation for automatic feeding, first, the lid stopper protrusion is hung on the lid stopper holding member so as to close the lid of the storage container. Thereafter, if necessary, food is supplied into the storage container and the screw rod driving means is started. The actuator is moved by the rotation of the screw rod, and the lid stopper protrusions of the storage container are sequentially pushed to open the bottom cover of the container and discharge the bait to the chute. When the rotation speed of the screw rod driving device is kept constant, the bait is released at a time interval determined by the arrangement interval of the bait storage containers, in other words, the lid stopper arrangement intervals of the plurality of containers.

  As described above, the feeding release time interval can be controlled by one actuator and feeding can be automatically performed, so that a compact and simple device can be configured as compared with the case where a lid opening / closing control means or actuator is provided in each storage container. It can be realized at a very low cost. If the following method is applied as the control method of the automatic feeding device of the present invention, it becomes possible to use the device more flexibly. In other words, a sensor is installed to detect that the actuator has approached the vicinity of the bottom lid stopper of each storage container, and the actuator is moved by driving the screw rod, and the sensor moves the actuator to one container lid stopper. When detected, the movement of the actuator is temporarily stopped, and the time counting means starts counting. When the time counting means counts the arrival of the feeding time, the screw rod starts to rotate again, and continues to drive the screw rod, that is, to move the actuator until the sensor detects the approach to the next adjacent storage container. The sensor is stopped when it is detected that the sensor has approached the lid stopper position of the next adjacent storage container of the actuator. At the same time as the actuator is stopped, the time count is started again, and when the time count reaches the bait release time interval from the next container, the actuator is further started toward the next adjacent container. After the actuator approaches and stops one storage container, the time count reaches the bait release time interval, the movement resumes, and it approaches the first container before it approaches the next container and stops again. Open the bottom lid of the container and release the food. In the same manner, the same operation is successively performed for successive storage containers. When an operation is performed in which the screw rod is continuously rotated at a constant speed, the feeding time interval is determined by the speed of the screw rod and the arrangement interval of the containers, and the degree of freedom is reduced. As described above, the control by the actuator approach sensor and the time count has the effect of freely setting the feeding time interval regardless of the rotation speed of the screw rod, and further enhances the utility of the automatic feeding device of the present invention.

  FIG. 2 is a layout diagram showing a schematic configuration of the invention as set forth in claim 2. According to a second aspect of the present invention, a bait storage container similar to that described in the first aspect is arranged on a pedestal so that the tip of the bottom cover stopper protruding portion according to the same claim is positioned substantially on the circumference. The cam mechanism rotating along the direction pushes the lid stopper in a direction away from the center of the circumference, thereby removing the lid stopper from the lid stopper holding material and opening the bottom lid of the storage container. Note that when the tip of the lid stopper protrusion is located approximately on the circumference and the rotating cam rotates approximately on the circumference, the rotating cam and the lid stopper protrusion tip contact each other, and the cam pushes the tip of the protrusion. The positional relationship is such that the lid stopper can be removed from the holding material.

 In addition, in Claim 2, the whole bait storage container arrange | positioned on the substantially circumference is mounted on the base which has a rotating shaft in the center of the said circumference | surroundings, these feed storage containers can be rotated by a rotation drive means, and the other cam is covered. It can also be configured to be fixed on the circumference formed by the tip of the stopper protrusion. In such an arrangement, when the storage container being rotated and moved by the rotation driving means approaches the cam, the tip of the cover stopper protrusion of the storage container hits the cam and the container bottom cover is opened. However, in general, a configuration in which the storage container is fixed and the cam is rotated is desirable from the viewpoints of downsizing the driving unit and downsizing the rotating unit. In the invention of claim 2, the lid stopper holding material should also be arranged on the circumference corresponding to the arrangement with the tip of the lid stopper protrusion.

  FIG. 3 shows a schematic configuration of the invention described in claim 3. The invention of claim 3 is a plurality of bait storage containers having a substantially flat plate-like container bottom cover that can be opened and closed and attached to the bottom of the container by a hinge. A plurality of containers arranged on a circumference are rotated with respect to the gantry around the point on the gantry by a rotation driving means. Further, below the rotating container is an opening obtained by cutting off a part of a locus of a belt-like ring drawn by the bottom cover when the container in a state where the container bottom cover is closed is rotated. Having a shape and an area where the lid opens downward with respect to the hinge in the range of the opening, and a relative position with respect to the belt-like ring (hereinafter referred to as an opening provided in the shielding plate or simply an opening) And at least an annular range formed by rotating the bottom lid of the container in a range other than the opening is covered with a shielding plate that does not have an opening large enough to open the bottom lid. The shielding plate and the lid on the bottom of the bait storage container (including the hinge part) should be provided with an appropriate gap so as to reduce the frictional force between the contact surfaces, or a material with little friction (for example, the lid may be a metal plate). Adopt a polymer material for the shield plate, or a material with low friction only at the contact portion between the lid and the shield plate), lubricate the mutual contact surface, or insert a roller between the lid or the shield plate Take appropriate measures such as

  When a plurality of rotating bait storage containers pass over the opening provided in the shielding plate, the lid covering the bottom surface thereof opens downward about the hinge by its own weight and discharges the bait. The attachment position of the hinge is selected so that the tangential direction of a circle drawn during rotation on the gantry of the container and the direction of the vertical opening / closing movement of the bottom lid at the opening are substantially parallel. That is, it is desirable to attach the hinge to the outer periphery of the bottom surface of the container and in the vicinity of the front end portion in the traveling direction of the rotational motion of the bottom surface. By placing the hinge as described above, the lid of the storage container falls and opens into the opening while the storage container passes over the opening, and then the lid again contacts the edge of the opening in the traveling direction with the progress of rotation, Once opened, the lid is automatically closed. When the hinge is provided at a position different from the above-described position, a separate guide or the like for closing the lid after passing through the opening is necessary. A chute for receiving the food discharged from the bottom of the food storage container and supplying it to the food box is provided at a position corresponding to the lower side of the opening.

  As shown in FIG. 4, the invention described in claim 4 has an arrangement of a bait storage container (a plurality of containers having a bottom surface with a hinge lid) and a shielding plate similar to those of claim 3. Is fixed to the gantry 33, and the shield plate 38 is made rotatable by the turntable 34. The plurality of containers arranged in a substantially circumferential shape are mounted on the table so as to keep a gap between the container and the gantry so that the shielding plate can rotate below or through appropriate friction reducing means. The shielding plate is disposed below the bottom surface of the container so as to be rotatable by the rotation driving means with respect to the gantry. The shielding plate is constituted by an opening having the same arrangement and configuration as described in claim 3 and a closing portion (having only a sufficiently small opening or a plate-like one), and the shielding plate rotates to claim 3. When the opening of either passes through the bottom of any container, the lid opens and releases food. Structures other than the above are the same as in the third aspect.

  The invention described in claim 5 is shown in FIG. In the invention described in claim 3 or claim 4, the bottom cover of the bait storage container is removed. By disposing the shielding plate and the bait storage container according to claim 3 or 4 in contact with each other or with a sufficiently small gap therebetween, the closing portion of the shielding plate functions as a lid. . Since the bottom of the container is closed except for the opening of the shielding plate and the bait in the container can be held in the same manner as the lid, the same function can be realized with a simpler configuration by removing the lid. In order to prevent bait spillage due to relative movement between the container bottom and the shielding plate, a sealing material 45 made of a soft material (such as rubber or plastic) is added to the container bottom to maintain a low frictional resistance with the shielding plate surface. In some cases, consideration must be given to preventing leakage of food. Other configurations are the same as those of the third or fourth aspect.

  It is an invention that can provide an extremely simple and easy-to-install compact automatic feeding apparatus for livestock, and is particularly effective in shortening the preparation period of livestock rearing experiments, which have a large limitation on installation time and cost, and reducing experimental costs.

  FIG. 1 shows the best mode for carrying out the invention of claim 1. In FIG. 1, six bait storage containers 2 are arranged above the gantry 1 in a row and arranged in two rows in a row. The number of food storage containers is appropriately determined according to the application. The number of this figure is an example. A chute 3 made of an inclined plate is provided below the bait storage container 2 within the legs of the gantry 1, and a bait box 5 is placed at the tip of the chute 3 as necessary. The bait box 5 is discharged from the bait storage container 2. Arrange the bait thrown into the so that the livestock can eat it. Between the containers 2 arranged in two rows, the actuator device 4 is attached to a gantry. As for the shape of the bait storage container 2, a cylindrical shape with a rectangular bottom surface is selected in FIG.

  The lid 7 attached to the bottom surface 6 of the bait storage container 2 is a plate-like member having an area that is substantially the same as or slightly larger than the bottom surface 6 of the container 2, has a hinge 8 at one end, and a part of the bottom surface 6 through the hinge. It can be attached. A lid stopper 10 including a rod-like member that can move substantially horizontally and has a protruding portion 9 protruding from the peripheral edge of the lid 7 by an elastic body in a normal state is attached to a position substantially opposite to the hinge mounting portion of the lid 7. An example of the lid stopper 10 is a mechanism as shown in FIG. 5, and a projection 9, which is a part of the lid stopper, is coupled to the lid 7 via a spring 11, and the spring 11 is deformed as shown in FIG. 5. In the absence, the protruding portion 9 is protruded from the periphery of the lid 7 in the direction opposite to the hinge 8. When a force is applied from the tip of the protruding portion 9 toward the peripheral edge of the lid 7, the spring 11 is deformed in the extending direction, and the protruding portion 9 is retracted toward the peripheral edge of the lid 7. The spring 11 is provided with an adjusting screw 12 for adjusting the position of the protruding portion 9. The position of the screw 12 is adjusted to adjust the length of the spring 11, that is, the position of the protruding portion 9. The contact position can be adjusted.

  As shown in FIG. 1, when the bait | storage container 2 is arrange | positioned on the mount frame 1, the protrusion part of the lid | cover stopper 10 makes a substantially horizontal straight line. In a normal state, a protruding portion 9 protruding from the periphery of the lid 7 is held from below, and a lid stopper holding material 13 that closes the bottom surface 6 of the container 2 is attached to the gantry. In FIG. 1, the stopper holding member 13 is a bar that is parallel to the linearly arranged one row of containers 2 and is horizontally attached to the gantry, and is a protruding portion of the lid stopper 10 of the two groups of containers arranged in one row. The lid is closed by placing 9 on the bar. The width of the crosspiece, which is the lid stopper holding member 13 (the dimension in the movement direction of the protrusion 9), is a dimension that can be removed from the crosspiece when the protrusion 9 is pushed in from the outside in the laterally movable range of the protrusion 9. .

  FIG. 6 shows an example of the configuration of the linear actuator 4. The actuator 4 is formed by fitting a rod-like member (screw rod) 15 provided with a male screw and a nut 16 having a female screw corresponding to the screw rod 15 into the rod 15. In addition, an actuator portion 17 connected to the nut and extending in the vertical direction of the screw rod axis direction is provided. The nut 16 is free to move in the axial direction of the rod 15 but is provided with a guide rail 20 that suppresses rotation around the axis. The screw rod 15 can be rotated by the driving means 18. As the driving means 18, an electric motor (including a speed reducer if necessary) is usually used. When the driving means 18 is operated and the screw rod 15 is rotated, the engaged nut moves in the rod axis direction. In the present embodiment, the guide rail 20 and the lid stopper holding member 13 are the same member and have both functions.

  As shown in FIG. 1, the linear actuator 4 is attached to the gantry so that its screw rod shaft is substantially parallel to a straight line formed by the lid stopper protrusion 9 of the storage container 2 arranged in a row. The actuator portion 17 of the linear actuator 4 contacts the tip of the lid stopper projection 9 of the container 2, moves the projection 9 in the horizontal direction, and pushes it in until it is released from the lid stopper holding material 13 (the tip of the actuator portion 17 (The amount of protrusion in the direction perpendicular to the axial direction of the screw rod 15). In FIG. 1, three containers 2 are arranged in two rows, and the lid stoppers 10 are arranged so as to face each other between the rows of the containers 2, and the linear actuator 4 is attached between the rows. It arrange | positions so that it can remove in the part 17. FIG. In addition, it is possible to arrange the necessary number of rows other than the two rows, or arbitrarily select the number of containers in each row. It goes without saying that the number and arrangement of linear actuators also need to be changed in response to changes in the arrangement of the containers.

  The lid stopper protruding portion 9 of the automatic feeding device configured as described above is supported by the holding material 13 to close the bottom surface 6 of the storage container 2 and the storage container 2 is replenished with feed. If it starts, the actuator part 17 will move, the lid stopper 10 will be removed sequentially, the bottom face of the container 2 will be opened, and the inside bait will be discharge | released to a chute | shoot.

  In FIG. 1, the lid stopper holding member 13 uses a cross-shaped member that also serves as the guide rail 20, but a similar function can be provided even if a single member is attached to an individual container. As a means for moving the lid stopper protrusion 9, an elastic body such as rubber or a leaf spring can be used in addition to the spring. It goes without saying that other configurations can be adopted for the number of elastic bodies depending on the specific application.

  As a control method of the drive means 18 of the screw rod 15 shown in FIG. 1, after filling the storage container 2, the drive means is continuously operated, and accordingly, the actuator unit 17 is moved along the screw rod 15. Basically, the bait in the corresponding container 2 is discharged by continuously moving and sequentially pushing the protrusions 9 of the lid stopper. However, in the case of such control, there is a drawback that the timing of releasing the bait by opening the bottom cover of the bait storage container 2 is determined by the speed of the driving means 18 and the change is not easy. As a control method for eliminating such drawbacks, a sensor 19 for detecting that the actuator unit 17 has reached one of the lid stoppers is provided for each container 2, and the sensor signal is connected to the control means as follows. It is possible to release food at an arbitrary timing by controlling to. After filling the storage container 2, the driving means 18 of the linear actuator 4 is started and the counting of the time counting means is started. The time counting means is configured to set the bait release timing in advance and issue a start signal for the driving means 18 at each set timing. The actuator unit 17 is moved by starting the driving means 18. When the sensor 19 detects that the actuator portion 17 has approached any of the containers 2, the detection signal is transmitted to the control means. The control means stops the driving means 18 in response to the approach signal. Even when the driving means 18 is stopped as described above, the time counting is performed by the time counting means, the arrival at the preset bait release timing is detected and transmitted to the control means, and the control means starts the driving means 18. Let After the driving means 18 is started again, the driving means is stopped when the actuator unit 17 approaches the container 2 arranged at the next adjacent position and the proximity detection sensor 19 detects it as described above. When the time counting means detects the arrival of the next bait release timing, the driving means 18 is started again, and if the driving means 18 is operated and stopped in the same manner, the bait can be released at a preset timing. In addition, it is easy to comprise so that the timing set to a time count means can be selected freely, Therefore The bait | feed discharge timing can also be selected arbitrarily corresponding to it.

  FIG. 2 shows an embodiment of the invention described in claim 2. In FIG. 2, the plurality of food storage containers 2 are arranged on a circumference centered on a point on the gantry 1. It is necessary to consider the arrangement of the container 2 on the circumference within a position accuracy range in which a rotating cam mechanism, which will be described later, can push the lid stopper protruding portion 9 of the container 2 to a position where it is removed from the stopper holding member 13. . The structure of the bait storage container 2 in FIG. 2 is substantially the same as that shown in FIG. 1 as shown in FIG. It is attached, and while the bait is stored, the front end protruding portion 9 of the lid stopper 10 is supported by the stopper support member 13 and the lid 7 is closed. The cam 21 pushes the protruding portion 9 of the stopper to remove it from the holding material 13, and the lid 7 falls with the hinge 8 as a fulcrum to open the container bottom. FIG. 2 a is an example of an embodiment, and other configurations that function similarly can be applied. The lid stopper holding mechanism 13 is arranged so as to form a substantially circumference corresponding to the container 2 being arranged on the circumference.

  In FIG. 2, the rotating cam mechanism 22 has a cam 21 that moves on the circumference with the point on the gantry as the rotation axis, and the cam 21 removes the lid stopper protrusion 9 of the container 2 from the holding mechanism 13. It is a mechanism that makes a circular motion around a possible position. The rotary cam mechanism 21 has a drive means 18 and a control means. As the rotary cam mechanism 22 rotates, the cam 21 removes the lid stopper 9 from the holding mechanism and discharges the bait in the corresponding container. It is comprised similarly to FIG. 1 except the container 2 being arrange | positioned on the periphery and providing a rotation cam mechanism instead of a linear actuator. As shown in FIG. 2, the sensor 19 is arranged so as to detect the approach of the cam 21 to any one of the support members 13, and the cam driving means 18 can be controlled in the same manner as described in the preceding paragraph 0027. is there.

  FIG. 3 shows an embodiment of the invention described in claim 3. The bait storage container 30 is composed of a plurality of cylindrical containers, and the container bottom surface 31 is covered or opened by a lid 32 that can be opened and closed by a plate-like member coupled to the bottom of the container 30 using a hinge 37. The plurality of containers 30 are mounted on a gantry 33 on a rotating table 34 that rotates about a point on the gantry 33 so that the bottom surfaces thereof are substantially circumferential and have substantially the same horizontal plane. It rotates and moves horizontally on the circumference. A rotation driving means 35 is installed on the turntable 34 to allow the container 32 to rotate. As shown in FIG. 7b in FIG. 7 which is a BB view of FIG. 3, an opening is provided 36 in a part of the range through which the container bottom surface on the gantry 33 passes. The radial dimension of the belt-shaped circumference of the opening drawn by rotating the container 30 is wider than the width of the lid 32 (the maximum length of the lid 32 in the direction perpendicular to the circumference), and the area thereof is that of the bottom lid 32. It is assumed that it is larger than the area plus the area of the hinge portion 37. In FIG. 3, the bait storage container is a cylinder, but this is only an example and is not necessarily limited to a cylinder. Although the number of containers is six, it goes without saying that other numbers may be used.

  The attachment portion of the hinge 37 is attached to the most distal portion of the bottom portion of the container 2 with respect to the rotation direction of the turntable 34. When the hinge is arranged in this way, when the bottom cover 32 of the container 30 rotating on the turntable 34 comes to a position included in the area of the opening 36, the cover 32 opens downward by the hinge, and the bait in the container 2. Is released. When the turntable further advances, the hinge 37 is released from the opening 36, and the portion of the lid 32 following the hinge contacts the edge of the opening 36 in the rotation direction, and the lid 32 moves upward and closes by a moment with the hinge as a fulcrum. .

  It should be noted that it is a space other than the opening 36 provided on the pedestal 33, and only a hole having a size that allows the container 2 to rotate and the belt-like portion to be drawn or closed so that the lid does not fall down is allowed. Is done. Such a closed area is called a shielding plate 38. A chute 39 is installed on the gantry below the opening 36. The lid 32 opened downward while passing over the opening 36 is removed from the opening area as shown in FIG. 7a in FIG. 7 which is an AA view of FIG. 3 and FIG. As the cover closes, the cover closing guide 40 that is closed again is attached to a member fixed to a shielding plate or similar frame, and the open cover 32 is pushed in the closing direction so as to be smoothly closed. Further, in order to smooth the relative motion with the shielding plate on the bottom surface of the lid 32, for example, a protrusion 41 made of a polymer material is provided to prevent the surface of the lid 32 and the shielding plate 38 from coming into direct contact. . However, the protrusion 41 is not necessarily required if the direct contact between the lid 32 and the shielding plate is not a problem.
