However, reference numerals for the same or similar components throughout the drawings will be uniformly used.

Also, in the following description, terms such as 'first' and 'second' are used to distinguish components having technical meanings within the same range for convenience. That is, any one configuration may be arbitrarily named a 'first configuration' or a 'second configuration'.

The accompanying drawings show applied embodiments of the present invention, and the technical idea of the present invention should not be construed as limited through the accompanying drawings. If it can be interpreted from the point of view of an expert belonging to this technical field that some or all of the figures shown in the drawings are not inevitably required for the practice of the invention, this does not limit the invention described in the claims.

1 shows the main configuration of a fishery product and a tray supplying device according to an embodiment of the present invention.

The aquatic product and tray feeding device 100 according to an embodiment of the present invention receives trays continuously or intermittently from an operator or an automatic tray feeding device, pours a certain amount of aquatic products into each tray, and sets trays containing aquatic products in advance. It is to pile it up and then discharge it. To this end, it includes a transfer unit 10 for moving the tray 200 in a horizontal direction, a supply unit 20 for putting fish in the tray, and a loading unit 30 for stacking the trays containing the seafood.

These components are installed on the frame 101 shown by omitting some detailed configurations, and are operated by a power source such as an electric motor, a hydraulic motor or a hydraulic cylinder.

2 shows a tray 200 used in an embodiment of the present invention. The tray 200 is approximately box-shaped in which the harvested marine products are contained. Here, marine products are fish or shrimp that cannot escape through the hole in the tray. For example, it may be anchovies that require self-drying.

The bottom and inner wall of the tray 200 are composed of a net for discharging water. The circumference of the tray 200 has a double wall structure that increases structural rigidity, and a recessed groove 210 is formed around the outermost circumference except for each vertex portion. The recessed groove 210 is to make it easy to put a hand in when lifting the tray 200, and the recessed groove 210 can be used as a handle.

In addition, as shown in the enlarged view of FIG. 10 (b), a step 230 is formed at the bottom of the tray 200, and the step 230 enters the top of another tray and stacks the trays. This makes it possible to prevent the stacked trays from collapsing easily.

Unlike the drawing, a tray with a pair of retractable handles may be used. In the case of a tray with a handle, the handle is folded over the tray, so that the tray stacked on top of it hangs over the handle.

After that, the stacked trays go into a self-sufficiency period and self-restraint the seafood.

Referring back to FIG. 1, the conveying unit 10 transfers the tray 200 in a horizontal direction (the tray enters from the right side of the drawing and is discharged from the left), and the sprocket 11 spans the left and right sides of the device. ), a chain 12 caught thereon, and a drive motor 13 that rotates the sprocket 11. In addition, as shown, support rollers, support sprockets, tensioners, etc. may be further provided between the sprockets at both ends to prevent sagging of the chain. Meanwhile, although not shown, the shown chain 12 may be driven by connecting a separate sprocket to the shaft of the drive motor 13 and then connecting the shown sprocket 11 as a separate chain.

The sprocket 11 and the chain 12 are provided as a pair side by side, so that the tray is stably placed on the chains 12, and the tray is moved together with the chain 12.

In the illustrated embodiment, the transfer unit 10 includes a first part 10A for horizontally transferring the trays 200 across the supply unit 20 and the loading unit 30, and the trays 200 from the loading unit 30 It is divided into a second part 10B to be discharged.

The second part 10B has a different inclination angle of the chain 12 from the first part 10A in order to discharge the trays 200 at an appropriate height for the next work (eg, cooking work). In particular, by forming the second part 10B downwardly inclined, the trays can be directly put into other devices with the force of quickly descending on the second part 10B, thereby eliminating the hassle of pushing and inserting the trays again. This second part (10B) may be omitted depending on the tray input height of the device for the next operation.

Meanwhile, the chain drive for transferring the tray 200 in the transfer unit 10 may be continuously performed while the work device 100 is operated. That is, the driving motor may be activated together with the start of operation of the work device to horizontally move the tray at all times. While the tray 200 is moving, a stopper unit 45 is used to supply fish to the tray and to suppress the movement of the tray when it is necessary to temporarily stop the transfer. In the embodiment of the present invention, a method in which the transfer unit 10 continuously operates is adopted.

Unlike this, if necessary in each process, the movement of the tray may be intermittently operated so that the movement of the tray is temporarily stopped.

1 and 3-4 relate to the supply unit 20 .

The supply unit 20 is installed above the transfer unit 10, and drops aquatic products onto the tray 200 passing by the transfer unit 10, and puts the seafood in the tray.

The supply unit 20 includes a hopper 21 for temporarily storing aquatic products and a quantitative supply valve 22 for supplying the aquatic products contained in the hopper 21 to the tray by quantity.

The hopper 21 is connected to a supply hose 211 for supplying marine products to be put into the tray. This supply hose 211 is connected to a pump (not shown) that pressurizes and delivers water and marine products together. Meanwhile, a water hose 214 may be provided to supply additional water to the hopper in order to secure the flow of aquatic products.

Although not shown, as an additional configuration, a water level detection unit for controlling the operation of the pump by detecting the water level in the hopper, a paddle device for appropriately stirring water and marine products, and the like may be provided in the hopper.

The bottom of the hopper 21 has a center portion inclined downward at the lowest level, and a connection hole 212 through which aquatic products exit is formed in the center of the bottom.

Meanwhile, the perforated plate 213 may be installed at regular intervals on the wall surface of the hopper 21, and the drain pipe 215 may be disposed in the space B partitioned accordingly. The drain pipe 215 may be disposed in the lower part of the space, and a valve may be provided in the drain pipe.

According to this configuration, when fresh water is supplied to the hopper 21 using the water hose 214 or the like, only the water can be discharged in a state in which the aquatic product is not blocked by the perforated plate 213 and does not flow out. Accordingly, it is possible to rinse the aquatic products during the operation while smoothly discharging the aquatic products through the connection hole 212 .

Meanwhile, the perforated plate 213 may be disposed in the entire area, but the perforated plate 213 may be disposed only in a part of the area (front and rear as viewed from the drawing) so that the supplied water is not immediately discharged when fresh water is supplied.

The quantitative supply valve 22 is mounted in the connection hole 212 and is located below the hopper 21, and as it rotates, a certain amount of aquatic products is dropped into the tray 200.

The water and fishery products contained in the hopper 21 are mixed and fall from a certain height to the tray through the quantitative supply valve 22. The shock that touches the tray spreads the water and seafood in all directions, spreading the seafood relatively evenly on the tray. Soon, the water drains through the mesh at the bottom of the tray, and the seafood remains in the tray.

4 shows a specific configuration of the quantitative supply valve.

In the illustrated embodiment, the metering supply valve 22 includes a valve housing 221, a rotating shaft member 222, wing plates 223 and a driving unit 224. Furthermore, the first switch unit (p1) or the amount control member 225 may be further provided as an additional configuration that can be omitted.

The valve housing 221 is a case forming a cylindrical inner space S, and an upper hole 221a connected to the connection hole 212 of the hopper is provided at the top of the inner space S, and the upper hole 221a and A lower hole 221b through which aquatic products are discharged into a tray is formed on the opposite bottom. Furthermore, a part of the valve housing 221 or a part of the hopper can be configured as a transparent window 216 so that the operator can inspect the internal situation at any time.

Here, the connection hole 212, the upper hole 221a, and the lower hole 221b are formed long in the front and back in a size corresponding to the width of the tray, so that the seafood is smoothly dispersed in the front and rear directions of the tray when the seafood is added.

The rotating shaft member 222 is mounted at the center of the circular cross-section of the inner space S formed by the valve housing 221, and is rotated by a driving unit 224 provided outside. Here, the drive unit 224 may include a motor for providing rotational force, a chain for transmitting power to the rotating shaft member, and a gearbox.

The plurality of wing plates 223 are radially provided on the rotating shaft member 222 to divide the circular cross-section of the internal space into a plurality of individual spaces S1. The number of wing plates 223 may be variously changed according to the design of the metering supply valve. In the illustrated embodiment, four wing plates 223 are provided, and the internal space is divided into four individual spaces S1.

In addition, a plurality of holes are formed in the wing plate 223 so that water or air can easily escape. Meanwhile, an auxiliary plate 226 may be attached to an end of the wing plate 223 . The auxiliary plate 226 is preferably attached to the side of the wing plate 223 in the direction of rotation. The auxiliary plate 226 is composed of a deformable soft member so that a gap does not occur between the wing plate 223 and the inner surface of the valve housing 221, thereby preventing marine products from being caught.

In addition, when the wing plate 223 rotates while facing the inner surface of the valve housing 221, it is deformed and then restored when the wing plate 223 reaches the lower hole 221b, so that the seafood is well dispersed in the tray 200 It may also serve as an aid to

The driving unit 224 limits the rotational angle range of the rotating shaft member 222 so that the marine products contained in each individual space escape through the lower hole 221b. In the illustrated embodiment, the driving unit 224 rotates the rotating shaft member 222 by 90 degrees or 180 degrees to operate so that the marine products contained in one individual space S1 are contained in each tray. At this time, detectors (not shown) are installed on the axis that rotates the rotating shaft member 222 at intervals of 90 degrees or 180 degrees, and proximity sensors (not shown) are installed to detect these detectors, so that the axis of rotation depends on the detection signal of the proximity sensor. By stopping the rotation of the member 222, the rotation angle of the rotating shaft member 222 can be more accurately limited.

Furthermore, an amount control member 225 may be provided to differently set the amount of aquatic product to be dropped into each tray from the quantitative supply valve according to the type, size or condition of the aquatic product. In addition, the process of manufacturing the wing plate 223 may be simplified by not forming a hole in a portion of the wing plate 223 closed by the amount control member 225.

The amount control member 225 is a structure that is detachably mounted on one side of the wing plate 223, and has an effect of reducing the volume of the individual space S1 by the amount of the fin occupied by the amount control member. Accordingly, the amount of marine products contained in individual spaces is reduced.

In the illustrated embodiment, the volume control member 225 in the form of a triangular prism is screwed to one surface of the wing plate 223 and is detachably coupled. At this time, in addition to the screw fastening method, various known coupling methods for detachably coupling the wing plate and the amount control member, such as a sliding coupling method, may be used.

Furthermore, after preparing a plurality of volume control members having different volumes, the volume control member may be replaced according to the volume of the individual space intended by the user.

The first switch unit p1 is used to start the operation of the driving unit 224 .

Here, the first switch unit (p1) is activated by interference with the tray entering the transfer unit, and may be, for example, a limit switch touched by the moving tray.

Alternatively, any one of a variety of well-known sensors such as a distance sensor, a contact sensor, and an optical recognition sensor for recognizing that the tray has arrived at a specific location may be employed as the first switch unit. The configuration of the first switch unit may be equally applied to the second and third switch units described below.

In the illustrated embodiment, the first switch unit p1 is positioned below the lower hole 221b to be interfered with by the tray 200 that begins to pass below the lower hole 221b.

At the same time that the first switch unit (p1) is activated, the driving unit 224 rotates the rotary shaft member 222 by a predetermined angle, and the aquatic products falling into the lower hole 221b fall on the tray.

At this time, the installation position of the first switch unit (p1) is adjusted in consideration of the moving speed of the tray by the transfer unit, the rotational speed of the rotating shaft member, and the falling time of marine products, or the activation time of the first switch unit and the start of rotation of the rotating shaft member. You can set a time difference between points in time.

The tray into which the fishery products are put is moved more horizontally by the transfer unit 10 and enters the loading unit 30.

1 and 5 to 11 relate to the mounting unit 30 .

In the illustrated embodiment, the loading unit 30 stacks a plurality of trays 200 by supporting while sequentially raising the trays that have passed through the supply unit, and when the trays 200 are stacked in a predetermined number of layers, the trays are moved. It is to automate the tray stacking work by discharging at once.

Specifically, the loading unit 30 includes a lifter 31 that pushes up the trays and a support unit 40 that operates to stack the trays on the right side. As an additional component that can be omitted, the second and third switch units p2 and p3 or the stopper unit 45 are included.

The lifter 31 pushes the transported tray 200 upward, and supports the drive unit 311 providing vertical motion and pushing the tray 200 upward while avoiding interference with other components such as a chain. structure 312.

The driving unit 311 is to lift and lower the support structure in a short height range, and one of known devices such as a scissor type or a cylinder type may be employed.

In FIG. 7, the support structure 312 supports the bottom of the tray 200, and adopts a frame structure that does not interfere with the chain 12, the stopper unit 45, and the second switch unit p2. In the illustrated embodiment, the support structure 312 includes a pair of top plates 313 formed long in a direction parallel to the chain coupled by vertically long pillars. Parallel top plates 313 support the bottom of the tray. Unlike this, the shape of the support structure 312 may be variously changed.

A recumbent rod-shaped protrusion 314 is mounted on the front end of the top plate 313 in contact with the bottom of the tray 200. Referring to FIG. 10(b), the bar-shaped protrusion 314 first contacts the front end of the bottom of the tray 200 when the support structure 312 rises and the top plate 313 grips the bottom of the tray. do. At this time, the step 230 on the bottom of the tray moves along the curved surface of the rod-shaped projection 314, so that the step 230 comes into contact with the side surface of the rod-shaped projection 314. In this way, the rod-shaped protrusion 314 aligns the position of the rising tray, making the rising tray constant every time. Therefore, the trays can be stacked correctly without being disturbed.

On the other hand, the stopper unit 45 is for limiting the position where the tray is raised by the lifter 31 on a plane, and temporarily hinders the movement of the tray so that the tray does not move further toward the exit due to the continuous operation of the transfer unit is to do

These stopper units are. It can be omitted if the operation of the lifter by the second switch unit (p2) described later is timely and set to be lifted directly up by the lifter during the process of moving by the transfer unit.

The stopper unit 45 is provided with a stop member 451 located on the movement path of the tray and hindering the movement of the tray, and an operating unit 452 that changes the position of the stop member 451 to allow the tray to move. do.

In the illustrated embodiment, the stopping member 451, when standing upright, touches the front end of the tray 200 moving by the transfer unit to hinder the movement of the tray, and does not interfere with the tray when it is tilted sideways, thereby preventing the tray 200 from being moved by the transfer unit. It is a locking plate that allows movement, and the operation unit 452 is a servo motor that erects or flips the locking plate.

This stopper unit 45 can be changed into various structures that suppress or release the movement of the tray.

The second switch unit (p2) is activated by the tray 200 entering the loading part 30, thereby starting the operation of the lifter 31.

In this case, not only the second switch unit p2 but also the third switch unit p3 may be involved in the operation of the lifter 31 . This will be described later.

The second switch unit (p2) is installed at about the height of the chain of the transport unit so that the tray is activated by the tray at the timing when the tray comes to the lifting operation position of the lifter (31).

In the illustrated embodiment, the second switch unit (p2) is installed on the left side of the stopper unit (45), the second switch unit (p2) is first activated by the tray, and then the tray (200) in the stopper unit (45) it gets caught

As soon as the second switch unit (p2) is activated, the lifter (31) starts to operate, and while the tray (200) moves to the stopper unit (45), the support structure (312) rises to the bottom of the tray, and the stopper unit (45) As soon as the tray touches, the support structure 312 may be set to lift the tray upward.

5 to 6 show a schematic mounting position of the support unit 40, and FIGS. 8 to 9 relate to the detailed configuration of the support unit 40. 11 also relates to the operation of the support unit 40.

The support unit 40 supports the tray 200 raised by the lifter 31, and as new trays are continuously supplied from below by the lifter 31, the trays are stacked in a plurality of layers.

Referring to FIG. 6 , a pair of support units 40 are mounted facing each other in the front and rear of the work device at intervals corresponding to the width of the tray.

The front end of the support block 42 protrudes from the facing surface of the support unit 40 .

In order to clarify the understanding of the following description, moving so that the front end of the support block 42 protrudes out of the support unit 40 is referred to as forward movement, and conversely, the front end of the support block 42 enters the support unit 40. The movement is called a retreat movement.

The support block 42 of the support unit 40 is retracted by the tray 200 that is raised by the lifter 31 so that the tray 200 can go up, and then the support block 42 is restored and moved up. It supports the tray 200.

Specifically, the support unit 40 includes a case 41, a support block 42, a spring 43, and a retraction operation unit 44.

The case 41 forms a space in which the support block 42 moves forward and backward, and long open holes 411a are formed in the left and right sides of the front plate 421 facing the side of the tray 200.

In the support block 42, the front end 421 is exposed to the outside through the open hole 411a, and the lower surface 421a of the front end 421 contacts the edge of the upper side of the side of the tray 200 that is raised, so that the support block is formed. It is formed in an inclined or curved surface so as to retreat, and the upper surface of the front end 421 is formed in a plane to support the bottom edge of the tray 200.

The support block 42 is supported by a plurality of rollers 412 mounted on the lower and upper plates of the case 41, so that it can move smoothly back and forth. In addition, a guide block 413 having a sliding hole 413a corresponding to the cross section of the support block 42 is provided in the middle of the case 41 to restrict the movement range so that the support block 42 does not escape. . In addition, the stopper block 422 mounted on the upper surface of the support block 42 comes into contact with the guide block 413 to limit the protruding length of the support block 42 .

The spring 43 is installed between the rear plate 414 of the case 41 and the support block 42 to elastically support the rear end of the support block 42 . The state in which the tip of the support block 42 protrudes out of the open hole 411a is maintained by the spring 43, and the support block 42, which has been retracted while the tray 200 rises, passes through the tray. restored again by

Meanwhile, the retraction operation unit 44 forcibly moves the support block 42 backward despite the elasticity of the spring.

In the illustrated embodiment, the retraction actuating unit 44 includes a wire 441 connected to the rear end of the support block 42 and a retracting actuator 442 that pulls the wire 441 . Here, the retreat driving unit 442 includes a first pulley 442a provided on the rear surface of the case to change the direction of the wire, a second pulley 442b provided on the upper end of the frame of the working device and over which the wire spans, and tension applied to the wire. It includes a swing arm 442c and a power motor 442d for rotating it.

The wire 441 is connected to the support block 42 of each opposing support unit 40, and when the swing arm 442c is lifted by the operation of the power motor 442d, the wire 441 is pulled and both support blocks (42) moves backward at the same time.

Although not shown, the retracting operation unit may be replaced with various devices for forcibly retracting and moving the support block. For example, the retracting operation unit may be replaced with a solenoid device for retracting and moving the support block, a mechanical pusher, and the like.

Referring to FIGS. 9 to 11 , the operation of stacking trays raised by the lifter 31 will be described.

In (a) of FIG. 11, the upper tray 200 is supported by the support unit 40, and the front end of the support block 42 enters the recessed groove of the tray, and the tray 200 is supported. The lower tray 200 is transported by the transfer unit 10 and is brought into the lifting operation position of the lifter 31 .

10 and 11 (b), the lifter 31 operates to raise the tray 200 below. The upper edge of the rising tray 200 contacts the inclined bottom surface 421a of the front end of the support block 42, and both support blocks move backward, and the tray 200 continues to rise between the gaps.

The upper tray supported by the support unit 40 falls onto the newly rising tray.

In (c) of FIG. 11, the two trays 200 piled up are further raised by the lifter 31, and the support block 42 pressed on the side of the tray protrudes back to its original length.

After that, as shown in (d) of FIG. 11, the lifter 31 goes down again, and the trays 200 that have been raised by the lifter 31 are supported by the front end of the restored support block 42. After that, the new tray is brought to the lifting operation position of the lifter by the transfer unit.

On the other hand, in the illustrated embodiment, the front end 421 of the support block 42 is expressed as being supported while entering the recessed groove 210 formed on the side of the tray 200, but in another embodiment, the front end of the support block is It is possible to change the structure or operation range of the working device to support a certain chin on the bottom or side.

Referring again to FIGS. 1, 5 to 6 and 9 , the third switch unit p3 is installed at a height interfered by the uppermost tray 200 when the intended number of trays are piled up.

In order to set the number of trays to be stacked differently, the height of the third switch unit p3 may be varied.

When the third switch unit p3 is activated, the loading unit 30 may start an operation for discharging the stacked trays 200 .

Specifically, when the second switch unit (p2) is activated together with the activation of the third switch unit (p3), the support block (42) of the loading part (30) is retracted to drop the loaded trays onto the newly transferred trays. and the suppression function of the stopper unit 45 is released so that all of the stacked trays are discharged through the transfer unit 10.

Looking at this series of operations sequentially, as a result of the repeated stacking operation, the third switch unit p3 is activated by the trays 200 on the support unit 40 due to the height of the stacked trays at some point.

When the second switch unit (p2) is activated while the third switch unit (p3) is activated (additionally, the tray enters the lifting operation position of the lifter 31), the operation of the lifter 31 is omitted and instead The retraction operation unit 44 is operated, and immediately the stopper unit 45 is released and operated.

First, as the retraction operation unit 44 is operated, the support block 42 moves backward, so that the trays supported by the support unit 40 fall onto the trays stopped by the stopper unit 45. As a result, the existing trays are combined with the additional trays to become the trays to be finally discharged. In addition, as the loaded trays fall, the activation of the third switch unit p3 is released.

Soon after, while the stopping member 451 is tilted by the operation unit 452 of the stopper unit 45, the stacked trays are discharged by the transfer unit 10.

After that, when the new tray activates the second switch unit p2, the operation of the retraction operation unit 44 is released so that the support block 42 can perform its original operation. In addition, since the third switch unit (p3) is in an inactive state, the lifter (31) normally operates to raise the tray, and the support unit (40) grips it.

By continuously performing these operations, it is possible to stack the trays containing the marine products at a certain height and discharge them.

Although the detailed description of the present invention described above has been described with reference to preferred embodiments of the present invention, those skilled in the art or those having ordinary knowledge in the art will find the spirit of the present invention described in the claims to be described later. And it will be understood that the present invention can be variously modified and changed without departing from the technical scope.
