Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for weighing and sorting articles, in particular, scallops, shrimp, and other fish and shellfish, which is optimal for weighing and sorting 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 ship a certain number of seafood of each class in a box. However, conventionally, for measuring the weight of such fish and shellfish one by one, for example, a weighing mechanism is disposed below an upper running portion of a belt conveyor, and the weight of each of the upper and lower running portions of the belt is measured. The scallop to be weighed, for example, is conveyed, and in the course of this belt-shaped conveyance, the weight is measured by a weighing mechanism disposed below the weighing mechanism. A gate plate, which is driven according to the measurement result weighed by the weighing mechanism, is provided, and selectively rotates around its 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 an apparatus, some fish and shells are likely to roll, and may roll on the weighing belt conveyor and fall outward. 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 this regard.

On the other hand, it is conceivable to use a bucket conveyor instead of a belt conveyor, supply weighed articles to the buckets, and sort the articles according to the weighed result. However, there are the following problems.

FIG. 20 shows a conventional bucket conveyor-based transport device in which a bucket is mounted between a pair of chains and horizontal and vertical transport is circulated by these chains.

[0005] In the transfer device 1, gear units 4, 5, 6, and 7 are supported in a rectangular base 3 formed by angles 2. The rotational force of a motor (not shown) is transmitted to a pulley 8 provided on the gear device 4 via a belt, and a driving force is transmitted to the conveying means 9 via the gear device 4.

[0006] As shown in FIG. 21, the conveying means 9 comprises a pair of two-chain chains 10 and 11.
A pair of shaft locking portions 12, 12 and 13, 13 are arranged on the strip chains 10, 11 at predetermined intervals. On the inner side of these two-chain chains 10, 11, plates 14, 15 are respectively arranged adjacent to the chains.

On the other hand, the bucket 16 has an opening on one side and a substantially trapezoidal cross section, and both ends of both side walls 16a and 16b arranged in parallel with the two-chains 10 and 11 are provided with shaft mounting members. Bosses 17a, 17b, 17c, and 17d are formed.

Bucket 16 having such a boss formed
The transport direction A indicated by an arrow in FIGS.
The long shaft 18 is inserted through the bosses 17b and 17d on the front side, and both ends of the long shaft 18 are inserted up to the two-chain chains 10 and 11 and locked by the shaft locking portions 12 and 13, respectively. 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 17 c, and both ends of the short shaft 19 are locked to the plates 14 and 15.

In this manner, the buckets 16 are continuously set on the gantry 3 at predetermined intervals. When goods are transported by a series of buckets 16 set on the gantry 3,
Articles are sequentially put 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, the bucket 16 is rotated about the other long axis 18 as a fulcrum, and the contents are dropped downward.

[0010] By the way, in such a transporting device using a bucket conveyor, the bucket 1 which is empty after the transport is completed.
Then, the carriage 6 runs on the lower traveling portion of the gantry 3 while being suspended by the long axis 18, further moves upwardly in the vertical direction, and near the end of the upward movement, the short axis 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 horizontal direction, and it is not possible to insert an article in a portion moving in such a posture. . Therefore, there is a limitation on a work space or the like using the bucket conveyor.
Further, in the above-described transport device, the short axis 19 is
In order to slide on the upper part, a lubricating means for the sliding part is required, and the apparatus is complicated. Further, if the hydraulic oil used in the lubricating means adheres to the inside of the bucket, there is a problem that the commercial value of the conveyed articles is impaired.

In a conventional bucket conveyor as shown in FIGS. 20 and 21, articles can be put into the bucket 16 only by the horizontal transfer path as described above. Assuming that one by one is weighed by the weighing mechanism and one by one, sorting may be performed according to the weighed value on the downstream side from the charging position. As described above, the ends 14 of the plates 14, 15
a, 15a, all buckets 16 are now in FIG.
As shown in FIG. 1, when one of the supports is lost, the article is turned around the rear shafts 12 and 13 to drop the article downward. The article is sorted and turned according to the weighing result. This is not possible with this conventional bucket conveyor.

[0013]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and it is possible to reliably measure the weight of each product, for example, even seafood such as scallops and shrimps, and After reliable weighing and sorting according to the weighing result, excellent maintainability, without limiting the supply position of goods, diversification of work space etc. can be achieved, 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 resetting means and which does not impair the commercial value due to adhesion of lubricating oil and the like.

With this shape, an 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 configured to be supplied one by one, and the scallops M received by the product receiving portion T by the operation of the ejection plate 114 described later are moved by the arrow a in the stroke of the ejection plate 114 as described later. The bucket 35 is supplied to the bucket 35 being transported by the vertical transport section of the bucket conveyor 32 disposed on the right side.

In FIG. 1 and FIG.
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 driving force of the gear 81 via the chain belt 80 '. The gear 81 is attached to a frame 82 fixed to a gantry. The gear 81 is wound around a gear 27 a directly connected to the motor 27 serving as the above-described driving source via a chain belt 83. Therefore, the scallop chain supply conveyor 78 is driven at a predetermined timing with the transfer speed of the bucket conveyor 32 according to the diameter ratio and the number of teeth of the gear 81 and the drive chain gear 79. Further, the electric motor 27 of the present embodiment is a variable speed electric motor whose 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 apparatus 20 for sorting the same kind of seafood by weight will be described below.

Now, the motor 27 is driven and the gear device 23
To five rows of two-row chains 33, 33, 33, 33, 33
Power is transmitted to the other gear devices 24, 25, 26 via the. Accordingly, four rows of bucket conveyors are transported in the device 20 in the direction of arrow B in FIGS. 8
The electromagnetic solenoids 64, 64,... 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 are weighing mechanism 9
One is weighed 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. In this vertical transfer path, the bucket 35
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 articles such as the scallop are thrown into the bucket 35 in the vertical transfer path, the bucket 35 does not swing. In the embodiment, the scallops and the like thrown into the bucket 35 are classified into eight groups by weighing.
It is input to the controller 200. The weighed scallops of scallop and the like are sorted by weight by this 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 the shells and the like are accommodated in the bucket, the travel distance of the double 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 engagement member 6 shown in FIG.
6 is in the state shown in the figure, and the rod portion 71 is disposed in front of the rear wall 35d of the desired bucket 35 which is going to pass immediately below. Therefore, the bucket 35 travels with the rear wall portion 35d abutting against the rod portion 71 of the engaging member 66, and the bucket 35 rotates counterclockwise about the shafts 51 and 54 in FIG. As a result, the scallop scallop contained therein falls to an appropriate position on the lower collecting chute 76 and is contained in the container.

Thereafter, similarly, in the subsequent bucket, a predetermined electromagnetic solenoid is also excited, and the scallop passes through the chute and is accommodated in a container by weight. 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-described 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 set freely according to the rotational force of the motor 27, the number of arranged bucket conveyors, and the like.

In the above embodiment, the article, ie, the scallops of the scallop, is loaded in the vertical transport path of the bucket conveyor. However, it can be loaded in the upper horizontal transport path. It can be set appropriately.

In the above embodiment, when the bucket 35 moves from the vertical transfer path to the horizontal transfer path, and vice versa, and when the scallops of the scallops are dropped, the bucket 35 automatically rotates about the shafts 51 and 54 as fulcrums. Since the front wall 35c and the rear wall 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. When this shaft 101 rotates 45 degrees from the phase shown in FIG. 11, it assumes the position 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 shown in FIG. 13 via the shaft 96 connected thereto, so that the discharge plate 110 fixed to the left end also takes the position shown. Further rotation by 45 degrees, that is, rotation by 90 degrees from the phase of FIG. 11, takes the position shown in FIG. 14, the lever 95 further swings right around the shaft 94, and the lever 97 moves right. At the same time, the left end moves downward. Therefore, the discharge plate 110 fixed to this end takes the position shown in the figure.

Further rotation by 45 degrees takes the position shown in FIG. 15, and in this phase, the lever 95 changes its moving direction to the left and swings. At the same time, the lever 97 moves to the left, but the left end further falls downward, and the discharge plate 110 fixed thereto takes the position where it falls downward. Further rotation 45 degrees, ie 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 around the axis 94 and is therefore pivotally connected to it. The lever 97 is also moved to the left, and the discharge plate 110 fixed to the left end falls further downward. When rotated further 45 degrees, it assumes the position shown in FIG. 17 and the lever 95 swings further leftward about the shaft 94, so that the lever 97 connected thereto also swings leftward, and both of them slightly move. Start to rise upwards. When it is further rotated 45 degrees, the position shown in FIG.
Moves slightly around the axis 94 to the left. As a result, the discharge plate 110 assumes the illustrated position. When rotated further 45 degrees, the lever 95 takes the position shown in FIG. 19, whereby the lever 95 swings greatly around the shaft 94, and this movement also causes the lever 97 to move significantly to the right and both upwardly. Moving. Therefore, the discharge plate 110 also moves greatly in response. 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 rotational phase shown in FIG. 11 is obtained.

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 placed as shown in FIG. Therefore, these three weighing plates 107 are integrated, and are connected to a pair of weighing connecting plates 106a and 106b extending upward at both ends thereof. At this time, the weight of the scallop M placed on the article receiving portion T is weighed by the load cell 111 that is present. Next, the discharge plate 112
Moves on the locus as described above, but the scallop M weighed and in the goods receiving portion T is rotated at a rotational phase between the rotational 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 114b of the discharge plate 114 in the rotation phase shown in FIG. 11, and the scallop M gradually descends following the above-described stroke. The scallop M can be weighed by the load cell 111 stably placed on the goods receiving portion T of the weighing plate 107, and the discharge plate 114 can be further advanced by advancing the rotation phase.
Is pushed out by the short edge portion 114a of the first bucket 35, and the scallops M are dropped and supplied to the next bucket 35.

The bucket 35 of the bucket conveyor 32
Is coincident with the supply timing of the scallops M supplied one by one from the chain supply conveyor 78, so that the next bucket 35 is surely at the position for receiving the next scallops.

In FIG. 1, drive gears 79, 81, 27
a, 28, and 29 are provided such that the items, for example, scallops M are supplied one by one each time the bucket 35 comes to a predetermined opposing position from the item weighing mechanism 90.
Although the number of these teeth and the gear diameter are set,
When the use of this device is started, 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 weighing mechanism 9 of the scallops M is moved from the chain supply conveyor 78.
4 and 90, the supply speed to the goods receiving portion T increases, and the weighing mechanism 90 is a continuous link mechanism and performs the above-described movement.
4 to the bucket 35 from the article receiving portion T.
Can be adjusted at the timing shown in FIG. 11, that is, the timing at which the bucket 35 can regularly receive the scallops. Thereby, the weighing of one of the above-mentioned scallops M and the scallops M after this weighing are performed.
During the vertical transfer of the bucket 35, the scallops M can be continuously and reliably supplied to each bucket 35.

Although the discharge plates in the other rows have not been described above, in the present 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 by four, and each bucket 35 of the bucket conveyor 32 arranged side by side is used. Can be supplied simultaneously.

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 and 54 projecting from the side walls 35a and 35b of the bucket 35.
5b.

Further, in the above embodiment, the front wall portion 35c and the rear wall portion 35d of the bucket 35 are formed in a flat plate shape, but like the bucket 77 shown in FIG. 10, the front wall portion 77c and the rear wall portion 35d are formed. A plurality of continuous slits 80 may be formed over 77d. By providing the slit 80 in this way, it is possible to remove moisture or the like adhering to the articles to be stored from the bottom during the transporting movement, and also to move articles such as tarako which easily adhere to the inner wall of the bucket 35 downward. Easy to drop. If it extends to the bottom center of the bucket 77,
The slit 80 may be formed only in the front wall 77c.
Further, by forming the slits, the weight is lightened, so that the load on the motor can be reduced.

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 fish and shellfish to be weighed. It can also be applied to scallops, etc.
Alternatively, other products 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
May be appropriately selected according to a desired relative position change 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 described in some cases, but of course the chain feeding conveyor is directly received at the item receiving portion T without receiving at the long edge portion. 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. However, such a guide piece 37 may be omitted. That is, the chain connecting pieces 38 are simply provided on both sides of the bucket, but the chains may be rotatably provided on the chains on both sides via the support shafts. Conveyor 3
An item, that is, a scallop may be loaded by the item weighing mechanism 90 in the vertical transfer path portion of the second vertical transfer path portion. Since the guide chute provided can quietly insert the guide chute therein, the bucket 35 having the same shape is prevented from being largely rotated and dropping the article. Further, in this case, in the horizontal transfer path portion, the electromagnetic solenoid 64 is excited, for example, as in the embodiment in accordance with the weighing result, so that the engaging member is engaged with the guide piece 37 to rotate. However, when the guide piece 37 is not provided instead, the shape of the engaging member of the solenoid 64 is engaged with a part of the bucket that is running, for example, the upper edge portion of the rear wall portion. Thus, the length and shape of the engaging member may be set.

In the above embodiment, the bucket conveyor 3
In the second vertical transfer path section, scallops M are supplied from the article weighing mechanism 90. Instead, one scallops from the same article weighing device is provided at the upstream end of the upper horizontal transfer path section. They may be supplied 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. Also, the solenoid 64 which operates in response to the signal weighed by the load cell 111 is not an upper horizontal transfer path, but a lower horizontal transfer path or a vertical transfer path on both sides, as in the embodiment. In this case, the articles housed by the engaging members in the transfer path 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 portion, one may be provided on the upstream side and a fixed engaging member may be provided on the downstream side without providing such a large number. In this case, one electromagnetic solenoid 64 has an article weighing mechanism 90.
Is compared with the set value of the result weighed by the load cell 111, the weight m between which a weight value is between a and b,
Then, by energizing the single electromagnetic solenoid 64, the bucket 35 containing the article is excited when it reaches below the item, and the bucket 35 is rotated by the engaging member to lower the scallops downward. The bucket containing the scallop of the other weight is guided to the downstream side as it is, and the downstream fixed engagement member,
It is also possible to incline everything and discharge it downward. As described above, the scallops are placed in a predetermined weight range, that is, a and b.
And other weights can be sorted.

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 article weighing / sorting apparatus of the present invention, regardless of the shape of the article to be weighed or discharged, the article is reliably received and weighed. Can be weighed, and the discharge or supply to each bucket can be made smooth and reliable from now on.

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 is in the horizontal transfer path section or the vertical transfer path section, articles can be put in, and accordingly, the work space using the bucket conveyor can be diversified. Also, there is no need for any reset means for changing the bucket to the position in which the bucket receives the goods, so that the entire structure can be simplified, and since there is no sliding portion when the bucket is transported, the hydraulic oil of the lubricating means is used. There is no danger of adhering to the article, and the article can always be transported in good condition.
