Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weighing / sorting apparatus for sorting articles, particularly, scallops, shrimp and other seafood by weighing and sorting them one by one.

[0002]

2. Description of the Related Art Recently, it has been widely practiced to sort out seafood such as scallops and shrimps one by one, and pack a certain number of seafood of each class into a box for shipment. However, in order to measure the weight of such seafood one by one, conventionally, for example, a weighing mechanism is arranged below the upper traveling portion of the belt conveyor, and the weight is measured one by one at the upper traveling portion of the belt. For example, scallops to be weighed are transported, and the weight is measured by the weighing mechanism arranged below the belt-shaped transporting process. A gate plate is provided, which is driven according to the measurement result measured by the weighing mechanism, and selectively rotates around the fulcrum according to the measurement result of the upstream weighing mechanism. Or do not rotate It has been known that was to sort so. However, according to such a device, some seafood may easily roll, and the fish may roll on the weighing belt conveyor and fall to the outside. That is, there are restrictions on the property and shape of the object to be weighed. In addition, since the weighing mechanism, such as the load cell, is disposed below the upper running portion of the belt, the structure is complicated, and since the items to be handled are seafood, it is necessary to clean the belt frequently. There is a drive system and a weighing mechanism on the back side of the, and it is difficult to clean them in order to prevent water from splashing on them. Poor maintenance in relation to this.

On the other hand, it is conceivable to use a bucket conveyor instead of the belt conveyor, supply the items weighed to this bucket, and sort the items according to the weighing result, but there are the following problems.

FIG. 20 shows a conventional bucket conveyor system in which buckets are attached between a pair of chains, and horizontal and vertical transportation is circulated by these chains.

In this carrier device 1, gear units 4, 5, 6, 7 are supported in a rectangular frame 3 formed by an angle 2. Rotational force by a motor (not shown) is transmitted to a pulley 8 provided in the gear device 4 via a belt, and driving force is transmitted to the conveying means 9 via the gear device 4.

As shown in FIG. 21, the conveying means 9 comprises a pair of two-strand chains 10 and 11, and these two chains
A pair of shaft locking portions 12, 12 and 13, 13 are arranged on the strip chains 10, 11 at predetermined intervals. Plates 14 and 15 are arranged on the inner sides of the two-strand chains 10 and 11, respectively, adjacent to the chains.

On the other hand, the bucket 16 has an opening on one side and a substantially trapezoidal cross section, and has both ends of both side wall portions 16a and 16b arranged parallel to the two-strand chains 10 and 11 for shaft attachment. Bosses 17a, 17b, 17c, 17d are formed.

Bucket 16 having such a boss formed
20 and 21, the conveyance direction A indicated by an arrow in FIG.
On the other hand, the long shaft 18 is inserted into the bosses 17b and 17d on the front side, and both ends of the long shaft 18 are inserted into the double-strand chains 10 and 11 and are respectively locked to the shaft locking portions 12 and 13. ing. On the other hand, the boss 17a on the rear side with respect to the transport direction A,
A short shaft 19 is inserted through 17c, and both ends of the short shaft 19 are locked to the plates 14 and 15.

In this way, the buckets 16 are continuously set on the gantry 3 at predetermined intervals. When goods are transported by the series of buckets 16 set on the gantry 3,
The goods are sequentially loaded into the bucket 16 in a horizontal state from a position above the gantry 3. Then, by arranging the end portions 14a, 15a of the plates 14, 15 at the place where the articles are accumulated, the short axis 1 of the bucket 16 passing therethrough
9 is removed from the plates 14 and 15, and the bucket 16 is rotated around the other long shaft 18 as a fulcrum to drop the contents downward.

By the way, in such a conveyor device using a bucket conveyor, the bucket 1 which has become empty after the completion of the conveyance.
After that, 6 runs on the lower traveling part of the gantry 3 while being suspended by the long shaft 18, and further vertically moves upward, and near the end of the upward movement, the short shaft 19 is placed on the plates 14 and 15 by appropriate means. Is reset.

Therefore, in the conventional bucket conveyor, the vertical movement of the bucket 16 is a suspension posture in which the opening is oriented in the lateral direction, and articles cannot be loaded in the portion that moves in such a posture. . Therefore, there is a limitation in the work space or the like where the bucket conveyor is used.
Further, in the above-mentioned transport device, the short shaft 19 is used for the plates 14 and 15
Since it slides on the upper part, a lubricating means for this sliding part is required, and therefore the device is complicated. Further, if the hydraulic oil used in this lubricating means adheres to the inside of the bucket, there is a problem that the commercial value of the conveyed product is impaired.

Further, in the conventional bucket conveyor as shown in FIGS. 20 and 21, it is possible to load the goods into the bucket 16 only through the horizontal transfer path as described above. It is conceivable that, assuming that the weights are individually loaded one by one by the weighing mechanism, sorting is performed on the downstream side of the loading position according to the weight value. The ends 14 of the plates 14, 15 as described above
a, 15a, all buckets 16 are now in FIG.
As shown in FIG. 1, when one of the supports is removed, it rotates around the rear shafts 12 and 13 to drop the item downward, which is sorted according to the weighing result and then rotated. To move it is not possible with this conventional bucket conveyor.

[0013]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is possible to reliably measure the weight of each item, such as seafood such as scallops and shrimps, and After reliable weighing, sorting is performed according to the weighing result, excellent maintainability, no limitation on the supply position of the goods, thus diversifying the work space and the like, and before moving to the horizontal transfer path. It is an object of the present invention to provide a weighing / sorting device for articles which does not require a complicated reset means and which does not impair the commercial value due to the adhesion of lubricating oil or the like.

[0014]

The above-mentioned object is to have a substantially triangular cross-section, the side walls of which are rotatably supported by a pair of chains by a support shaft. In this suspended state, the front wall and The rear wall portion is shaped so as to be inclined upward, and a plurality of parallel slits are formed between the outer edge portions of the both wall portions, and at least one of the both side wall portions extends substantially vertically in the suspended state.

At least one actuator disposed in the vicinity of the vertical transfer path portion or the horizontal transfer path portion on the downstream side is driven according to the weighing result of the item weighed by the item weighing mechanism,
The actuator is not driven because the bucket is rotated around the support shaft by engaging with the guide piece of the bucket that stores the item and the item that is stored is dropped downward. The bucket which advances to the downstream side is configured such that the guide piece is engaged with an engaging member disposed in the vicinity of a vertical transfer path portion or a horizontal transfer path portion on the further downstream side to rotate around the support shaft. The product weighing mechanism is arranged such that a plurality of first plate members are arranged at intervals so that the stored products are dropped downward, and the first plate members are used to supply the product from above. An item receiving section for receiving an item supplied to one by a chain belt conveyor is formed, and a weigher for weighing the weight of the item received by the item receiving section is connected to the first plate member and disposed. So that it can pass through each gap of the first plate The plurality of second plate members provided are fixed to the connecting rod of the lever crank mechanism, the second plate member is driven by the rotation of the crank of the lever crank mechanism, and the second plate member causes the gap to move during the stroke. When passing, the article weighed by the weigher in the article receiving section is received by the second plate member and separated from the article receiving section, and discharged into the bucket. The drive gear of the chain conveyor, the The drive gear of the lever crank mechanism and the drive gear of the product supply chain belt conveyor are mutually wound around a chain belt and driven by a common electric motor, and the electric motor has a variable speed. It is achieved by the heavy / sorting device.

[0015]

[Operation] The bucket rotatably supported by the support shaft is
Since the opening is always facing upward in the suspended state, the product can be loaded from any position, and the loaded product is stored in the space defined by the front wall and the rear wall. It The stored items can be removed from the bucket by rotating the bucket about the support shaft, and can be removed at any position. Also, it can be smoothly removed by the guide piece.

In the article weighing mechanism, a plurality of first plate members are arranged at intervals, and articles, for example scallops, are supplied from the article supply chain belt conveyor above to the article receiving portion formed by the first plate materials. To be done. Thus, the weight of the scallop currently being received can be weighed via the first plate member by the weigher connected to the first plate member. On the other hand, the second plate material moves in a predetermined closed loop by driving the lever crank mechanism through the gaps between the plurality of first plate materials. When moving in a predetermined stroke while receiving an item in the receiving unit, the item can be detached from the item receiving unit and supplied to the bucket. After that, the plurality of second plate members move in accordance with a predetermined stroke, and when passing through the gaps of the plurality of first plate members again, while supporting the weighed items already supplied from above, the It can be discharged into a bucket. The supply of the goods to the goods receiving portion and the supply of the goods to the bucket are surely performed at a timing.

As described above, the items, for example, scallops and shrimps can be weighed one by one and smoothly discharged into the bucket, but the first plate members are arranged at intervals. In addition, since the article receiving part can have a shape corresponding to the item to be weighed, for example, if it is a belt type, it is unsuitable to roll easily, but depending on the shape of the item receiving part of the first plate member. The fish and shellfish of any shape can be reliably weighed and can be smoothly discharged into the bucket.

If a weigher for weighing the articles received by the article receiving section is arranged above the article receiving section, water can be easily sprayed from above the first and second plate members during cleaning. It can be cleaned and in this case does not have any adverse effect on the weigher, eg load cell. Moreover, since the fixed article receiving portion can receive and weigh articles in a stationary state, stable and accurate values can be weighed, and the second plate material can be quickly discharged to the next process. You can Further, when the guide piece is brought into contact with the vertical guide member in the vertical transfer path portion to guide the bucket, even if the product is fed into the bucket at a high speed, it does not fall by rocking. Further, since the bucket is formed with a plurality of slits, cleaning with water is facilitated while reducing the load on the bucket chain conveyor.

Four rows of continuous bucket conveyors are formed between the strip chains 33, 33, 33, 33, 33.

On the other hand, in the upper horizontal transfer path portion of the gantry 22, as shown in FIGS. 7 and 8, above the pair of two-strand chains 33, 33, each has a U-shaped cross section in the chain conveying direction. Extending along and mounting flanges 59a, 59
A solenoid mounting member 59 having b in the opening is fixedly installed on the apparatus frame. The bottom plate 59c of the solenoid mounting member 59 has a large hole 60 and a small hole 6 at predetermined intervals.
1 and a pair are formed in pairs. The solenoid mounting plate 59 is integrally assembled by bolting between the mounting flange portions 59a and 59b and the device frame, and the position is adjusted by the long hole 62.

A predetermined number (8 in the embodiment) of electromagnetic solenoids 64 are accommodated in the space 63 defined by the solenoid mounting member 59. These electromagnetic solenoids are screwed to the bottom plate 59c of the mounting member 59. It is fixed. Figure 9
As shown in, the engaging member 66 is attached to the actuator 65 of the electromagnetic solenoid 64. Engaging member 66
Is formed in a substantially L shape from the short side arm portion 73 and the long side arm portion 68 with the connecting portion 72 having the rotating shaft 67 as a boundary. The rotating shaft 67 is rotatably supported by a fixed plate (not shown) arranged so as to hang down from the solenoid mounting member 59. At a tip portion of the long side arm portion 68 of the engaging member 66, a substantially L-shaped hook portion 70 having a cutout portion 69,
A rod portion 71 extending downward from the hook portion 70 is formed. A torsion coil spring is built in the connecting portion 72.

In the engaging member 66 thus formed, the short side arm portion 73 is inserted into the large hole 60 from below the solenoid mounting member 59, and the hook portion 70 of the long side arm portion 68 is small. It is inserted in the hole 61 and is installed in the solenoid mounting member 59. Even if an external force that rotates counterclockwise around the rotation shaft 67 in FIG. 9 acts on the long side arm portion 68, the engagement member 66 releases the force of the torsion coil spring when the force is released. The force causes it to return clockwise and restore the natural state of the torsion coil spring.
When the engaging member 66 rotates, the one end portion 70a of the hook portion 70 and the one end portion 71a of the rod portion 71 come into contact with the bottom plate 59c of the solenoid mounting member 59, whereby the rotation range of the engaging member 66 is increased. Regulated.

When the electromagnetic solenoid 64 is energized from such a non-excited state, the actuator 65 is in the solid line position, and at the same time, the engaging member 66 is in the lower position as illustrated. At that time, one end portion 70a of the hook portion 70 contacts the bottom plate 59c of the mounting member 59,
By attaching a cushioning material 58 such as urethane rubber to a portion of the hook portion 70 that comes into contact with the one end portion 70a, generation of abnormal noise due to a collision is prevented. Similarly, if a cushioning material 74 is attached to a portion that abuts the one end portion 71a of the rod portion 71 when the engaging member 66 is at the upper position, abnormal noise due to a collision at the time of ending the excitation is generated. Occurrence can be prevented.

Both ends of 9 are fixed to the weight connecting plates 106a and 106b hanging from the load cell 111. The load cell 111 is fixed to an upper stationary portion S ′ and is a known Roberval mechanism, which vertically connects the weight connecting plate 10
It is configured to receive the force applied to 6a and 106b. The weighing plate 107 has a substantially ladle shape as described above, and due to this shape, the article receiving portion T having a substantially V-shaped cross section is constituted by these three plate members. As shown above, for example, scallop M is received. Further, although the discharge plate 114 is also composed of three sheets in this embodiment, they perform the operations described later, and the chain supply conveyor 78 is provided on the left side of them, as shown by the arrow. To 1
The scallops M are supplied one by one, and the scallops M received in the article receiving portion T by the operation of the discharge plate 114, which will be described later, are indicated by an arrow a during the stroke of the discharge plate 114. At the vertical transfer portion of the bucket conveyor 32 arranged on the right side, the bucket is being supplied to the bucket 35 being transferred.

In FIG. 1 and FIG. 2, the weighing mechanism 9 for articles is shown.
On the upstream side of 0, a scallop chain supply conveyor 78 formed by connecting a number of elements having a V-shaped cross section is arranged in four rows in this embodiment as shown in FIG. And
Although only the drive chain gear 79 is shown in this figure, it receives the drive force of the gear 81 via the chain belt 80 '. The gear 81 is attached to a frame 82 fixed to a frame, which is wound around a gear 27a directly connected to the motor 27, which is the above-mentioned drive source, via a chain belt 83. Therefore, the scallop chain supply conveyor 78 is driven at a predetermined speed with the transfer speed of the bucket conveyor 32 in accordance with the diameter ratio and the number of teeth of the gear 81 and the drive chain gear 79. Further, the electric motor 27 of this embodiment is a variable speed electric motor, and its rotation speed can be adjusted.

The apparatus 20 equipped with the bucket conveyor according to the embodiment of the present invention is constructed as described above, and the apparatus 20 is used as a sorting apparatus based on the weight of marine products such as scallop scallops and tarako. ing. The operation of the device 20 for sorting such seafood of the same type by weight will be described below.

Now, the motor 27 is driven and the gear device 23
To 5 rows of double-strand chains 33, 33, 33, 33, 33
The power is transmitted to the other gear devices 24, 25, 26 via the. Therefore, the four rows of bucket conveyors, which are supported between the two double-stranded chains 33, 33, are transferred in the apparatus 20 in the direction of arrow B in FIGS. 1 and 2. 8
.. 64 are all in the non-excited state, and the corresponding engaging members 66 are all in the upper position. On the other hand, scallop scallops etc. have a weighing mechanism 9
One is weighted by 0. Then, the weighed scallops and the like are placed in a bucket 35 that conveys a vertical transfer path portion between the gear device 26 and the gear device 23 in the device 20.
Supplied individually. The bucket 35 is
As shown in FIG. 6, the curved portions 37a, 37 of the guide piece 37 are
Since b comes into contact with the vertical guide member 55 to guide the traveling in the vertical direction, the posture is kept constant. That is, even if an article such as a scallop is put into the bucket 35 in the vertical transfer path, the bucket 35 does not rock. In the embodiment, the scallops and the like put into the bucket 35 are sorted into eight groups by the weight, and to which group the scallops belong, after weighing,
It is input to the controller 200. Then, the weighed scallop scallops and the like are sorted by weight by the device 20 and stored in groups in the lower container. The sorting operation will be described below.

The group by weight corresponds to any electromagnetic solenoid. After accommodating the scallops or the like in the bucket, the travel distance of the two-row chain 33 until reaching the corresponding electromagnetic solenoid is calculated by a pulse encoder or the like, and after a predetermined time, the corresponding electromagnetic solenoid 64 is excited for a predetermined time. It has become. When the electromagnetic solenoid 64 is excited, the actuator 65 and the engaging member 6 in FIG.
6, the rod portion 71 is disposed in front of the desired rear wall portion 35d of the bucket 35 that is about to pass immediately below, in the traveling direction. Therefore, since the bucket 35 travels with the rear wall portion 35d in contact with the rod portion 71 of the engaging member 66, the bucket 35 rotates counterclockwise about the shafts 51 and 54 in FIG. As a result, the scallop scallops that have been stored fall into appropriate positions on the lower collecting chute 76 and are stored in the container.

Thereafter, similarly, in the subsequent bucket, a predetermined electromagnetic solenoid is excited, and the scallops pass through the chute and are housed in containers of different weights. Therefore, the scallop scallops are sorted by weight within a predetermined range and housed in a container or the like.

When the bucket 35 finishes carrying the contained items, the front wall portion 35c and the rear wall portion 35d return to the upward inclination by their own weight, and the vertical transfer path portion downward from the remaining horizontal transfer path portion and the After traveling along the lower horizontal transfer path, the posture is again held by the guide piece 37, and the vertical transfer path between the gear device 26 and the gear device 23 is transferred.

The bucket conveyor according to the embodiment of the present invention performs the above operations, but has the following effects. That is, when marine products or the like are transported, regular cleaning is performed for hygiene, but since the electric electromagnetic solenoid 64 is located above the device, cleaning with water or the like is easy. Further, the processing capacity can be freely set by the rotational force of the motor 27, the number of arranged bucket conveyors, and the like.

Further, in the above-mentioned embodiment, the article, that is, the scallop column is put in the vertical transfer path of the bucket conveyor, but it can also be put in the horizontal transfer path at the upper side, and the input position can be changed. It can be set appropriately.

Further, in the above embodiment, the bucket 35 is automatically rotated about the shafts 51 and 54 as a fulcrum when moving from the vertical transfer path to the horizontal transfer path and vice versa and when dropping the scallop scallops. However, since the front wall portion 35c and the rear wall portion 35d are inclined upward, no complicated resetting means is required.

The lever crank mechanisms 91 and 91 'are constructed as described above. When the shaft 98 is rotated at a constant speed, the shaft 1 fixed to the crank plate 99 is thereby produced.
01 rotates at a constant speed along the locus C. This shaft 101 takes the position shown in FIG. 13 when rotated 45 degrees from the phase shown in FIG. The lever 95 swings around the shaft 94 from the position shown in FIG. 11 by a certain angle. The lever 97 takes the position as shown in FIG. 13 via the shaft 96 connected to it, so that the discharge plate 110 fixed to this left end also takes the position shown. When it further rotates 45 degrees, that is, when it rotates 90 degrees from the phase of FIG. 11, it takes the position shown in FIG. 14, the lever 95 swings further around the shaft 94 to the right, and the lever 97 moves to the right. At the same time, its left end moves downward. Therefore, the discharge plate 110 fixed to this end takes the position shown.

When it is further rotated 45 degrees, it takes the position shown in FIG. 15, and in this phase, the lever 95 changes its moving direction to the left and swings. Along with this, the lever 97 moves to the left, but the left end portion further falls downward, and the discharge plate 110 fixed to this also takes a position where it also falls downward. Further rotation of 45 degrees, that is, 180 degrees from the rotation phase of FIG. 11, takes the position shown in FIG. 16, in which the lever 95 swings to the left about the axis 94 and is therefore pivotally attached thereto. The lever 97 being moved also moves to the left, and the discharge plate 110 fixed to the left end of the lever 97 further falls downward. When it is further rotated by 45 degrees, it takes the position shown in FIG. 17, and the lever 95 swings further to the left around the shaft 94. Therefore, the lever 97 connected thereto also swings to the left, and both are slightly moved. It begins to rise upwards. When it is further rotated 45 degrees, the position shown in FIG.
Moves slightly to the left about axis 94. As a result, the discharge plate 110 takes the illustrated position. When it is further rotated by 45 degrees, it takes the position shown in FIG. 19, and this time, the lever 95 swings largely around the shaft 94, and this movement causes the lever 97 to move greatly to the right and also to move upward. Moving. Therefore, the discharge plate 110 also moves largely accordingly. When it is further rotated by 45 degrees, the lever 95 swings largely to the right around the shaft 94, and along with this, the lever 97 also moves to the right, and at the same time, its left end portion largely moves upward. Therefore, the initial rotation phase shown in FIG. 11 is taken.

As described above, the crank plate 99 fixed to the shaft 93 moves along the stroke indicated by the locus C by the uniform rotational motion of the shaft 93. 114 is performed in such a stroke, in the rotation phase as shown in FIG. 14, or on the article receiving portion T formed on the upper side portion of the weighing plate 107 as the first plate material during the stroke. One scallop M is supplied from the chain supply conveyor 78 on the left side, which is shown in FIG.
It is mounted as shown in FIG. Therefore, these three weighing plates 107 are integrated, and are joined to the pair of weighing connecting plates 106a and 106b extending upward at both ends thereof, so that they are joined to their upper ends. At this time, the weight of the scallop M placed on the article receiving portion T is measured by the load cell 111 present. Then the discharge plate 112
Moves along the locus as described above, but the scallop M on the article receiving portion T is weighed and the short edge portion 114a of the discharge plate 114 is rotated at a rotation phase between the rotation phases shown in FIGS.
Then, the scallop M received by the receiving portion T is pushed out as shown in FIGS. 19 and 11. Therefore, as shown in FIG. 11, the vertical portion of the bucket conveyor 32 arranged on the right side is dropped and supplied to one of the buckets 35 being transferred as shown by an arrow a. In some cases, a guide chute may be provided to ensure this supply.

As described above, one scallop M is supplied to the bucket 35. During this process, the next scallop M is already supplied from the chain supply conveyor 78 to the article receiving section T, and as described above. However, the timing of supply from the chain supply conveyor 78 may be the rotational phase as shown in FIG. 11, and in this case, the scallop M may be so-called soft landing. it can. That is, the scallop M from the chain supply conveyor 78 is received at the long edge portion 114b of the discharge plate 114 in the rotation phase shown in FIG. 11, and the scallop M gradually descends following the above-described process, but this causes quietness. The weight of the scallop M can be stably weighed by being placed on the article receiving portion T of the weighting plate 107, and the discharging plate 114 can be further weighted by advancing the rotation phase.
The scallop M is pushed out by the short edge portion 114a of the No. 1 and is dropped and supplied to the next bucket 35.

The bucket 35 of the bucket conveyor 32
Of the scallop M is supplied from the chain supply conveyor 78 one by one, so that the next bucket 35 is surely in a position to receive the next scallop.

In FIG. 1, drive gears 79, 81, 27
a, 28 and 29 are provided such that the articles are fed from the article weighing mechanism 90 one by one, for example, one by one each of the scallops M when the buckets 35 come to a predetermined opposing position.
Although the number of teeth and the gear diameter are set,
When starting the use of this device, the rotation speed of the electric motor 27 is adjusted so as to be performed at a desired timing. That is, when the electric motor 27 rotates, the chain feeding conveyor 78 moves the scallop M to the article weighing mechanism 9
Although the feeding speed of the articles 4 and 90 to the article receiving portion T is increased, the weighing mechanism 90 is a continuous link mechanism and performs the above-described movement.
4 is pushed out from the article receiving portion T to the bucket 35.
11 can be adjusted at the timing shown in FIG. 11, that is, the timing at which the scallop M is regularly received by the bucket 35. As a result, the weight of one of the above scallops M and the scallop M after this weighting are measured.
The scallops M can be continuously and reliably supplied to each bucket 35 during vertical transfer of the buckets 35.

Further, when the scallop M is loaded into the bucket 35 during vertical transfer of the bucket 35 by bringing the guide piece 37 into contact with the vertical guide member, the bucket 35 is prevented from swinging even if it is rapidly loaded. Therefore, the scallop M does not drop downward.

Although the discharge plates in the other rows have not been described above, in this embodiment, a plurality of rows are provided as described above and the same operation is performed. Further, since these rows are operated in synchronization, if four rows are provided as in the embodiment, four scallops M are simultaneously weighed, and each bucket 35 of the bucket conveyors 32 arranged in parallel. Can be supplied at the same time.

The weighing and assorting device for articles including the bucket according to the embodiment of the present invention has been described above.
The present invention is not limited to the above embodiments, and various modifications can be made based on the technical idea of the present invention.

For example, in the above embodiment, the bucket 35
Is rotatably supported by two shafts 51, 54 projecting from the side wall parts 35a, 35b of the bucket 35. These shafts are one, and both side wall parts 35a, 3 of the bucket 35 are
It may be placed between 5b.

Further, although the present invention is applied to the marine product transporting apparatus in the above embodiments, it is of course applicable to other products such as agricultural products such as chestnuts.

Further, in the above embodiment, the bucket conveyor is constituted by four rows as shown in FIG. 1, but it may be one row or more, and the electromagnetic solenoids, chutes, etc. may be set in appropriate numbers. Can be changed.

In the above embodiment, the bucket conveyor having a plurality of rows, that is, four rows, has been described, and the scallop has been described as the seafood to be weighed. However, the seafood is not limited to this, and other small seafood, shrimp. It can also be applied to scallops, etc.
Alternatively, other items may be used instead of seafood.

Further, although the lever crank mechanism as the four-bar rotation mechanism has been described in the above embodiments, the levers 95, 97, 99 constituting each link are provided on the discharge plate 104 fixed to the lever 97, as desired. The length can be selected according to the movement to be performed, and the weighing plate 107 that moves by the rotation of the shaft 98.
And the relative shape of the discharge plate 114, or the discharge plate 114
It may be appropriately selected according to the desired change in relative position with respect to the weighing plate 107.

Further, the shape of the discharge plate 114 is not limited to that shown in the drawing, and the mounting position is also the lever 9.
It is not necessary to attach it to the left end portion of 7, and the other portion may be provided. In short, the discharge plate 114 performs a movement corresponding to the movement of the lever 97 of the lever crank mechanism 1. Should be performed.

Therefore, in the above-described embodiment, the operation of softly landing on the article receiving portion T at the long edge portion of the mounting plate 110 has been explained in some cases. Even if it is dropped and supplied from 78, if the drop height is small, it can be used for the weight.

Further, in the above embodiment, the guide piece 37 is attached to one side wall portion of the bucket 35, so that a stable posture is assured even when an item is loaded in the vertical transfer path portion of the bucket conveyor 32. Depending on how it is thrown in, it is guaranteed not to drop the thrown goods outward by pivoting around the support shafts on both sides. Further, in the upper horizontal transfer path portion, the bucket 35 is forcibly rotated at this position by selectively engaging with the engaging portion of the electromagnetic solenoid 64 disposed above the guide piece 37. Therefore, even when the bucket 35 is moving at high speed, the bucket 35 can be surely tilted.

In the above embodiment, the bucket conveyor 3
The scallops M are supplied from the item weighing mechanism 90 in the vertical transfer path section 2 instead of the above, but instead of this, one scallop is supplied from the similar item weighing device at the upstream end of the upper horizontal transfer path section. You may make it supply one by one. Alternatively, scallops may be supplied by a similar article supply mechanism 90 in the lower horizontal transfer path section or the right vertical transfer path section in FIG. Further, the solenoid 64 that operates by receiving the signal measured by the load cell 111 is not the upper horizontal transfer path section as in the embodiment, but the lower horizontal transfer path section or the vertical transfer path sections on both sides. In any of the above, the article accommodated by the engaging member in the transfer path portion may be discharged to the outside.

In the above embodiment, the electromagnetic solenoid 64 is used.
Although eight are provided for the upper horizontal transfer path, one may be provided upstream and a fixed engaging member may be provided downstream, without providing a large number. In this case, one electromagnetic solenoid 64 is provided with the item weighing mechanism 90.
By comparing with the set value of the result weighed by the load cell 111, the weight value m between a and b is a certain weight m.
If so, by exciting this one electromagnetic solenoid 64, when the bucket 35 accommodating this item reaches below this, the bucket 35 is rotated by the engaging member and its scallop is moved downward. The bucket containing the scallops other than that is guided to the downstream side as it is, and by the fixed engagement member on the downstream side,
It is also possible to tilt all and discharge downward. As described above, the scallop is put in a predetermined weight range, that is, a and b.
It is possible to sort into the weight between and and the other weight.

Further, in the above embodiment, the scallops M in the article receiving portion T are discharged to the buckets of the bucket conveyor by being pushed out by the short edge portion 114a of the discharge plate. The scallops received by the second plate member may be once discharged when being transferred above the gap S and discharged to the bucket when the process is further advanced.

Further, in the above embodiment, the gravitation plate 107 is adapted to weigh the scallop M by the gravity applied to the weighing connection plate 106a hanging from the load cell 111 arranged above. Alternatively, the scallops M placed on the article receiving portion T may be weighed.

[0070]

As described above, according to the apparatus for weighing and sorting articles of the present invention, the weight of the article to be weighed or discharged is reliably received regardless of the shape of the article to be weighed or discharged. Can be weighed, and the discharge or supply to each bucket can be made smooth and reliable.

When the load cell as the weighing mechanism is arranged above, the weighing plate and the discharge plate are washed by spraying water onto the article receiving portion T from below the load cell when washing with water for maintenance. Since the load cell can be installed and no water is sprayed on the load cell, its maintenance work is easy. Of course, as shown in the figure, the motor for rotating the shaft can transmit the rotational force from the motor arranged at a distance by the chain belt, so that there is no concern that water will be sprayed on the drive unit. Further, even if the bucket has a horizontal transfer path portion and a vertical transfer path portion, articles can be loaded, so that the work space in which the bucket conveyor is used can be diversified. Further, no resetting means for changing the attitude of the bucket to receive the goods is required, the entire structure can be simplified, and since there is no sliding portion when the bucket is transported, the operating oil of the lubricating means is not used. There is no risk of the product sticking to the product, and the product can always be conveyed in good condition.
