BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weighing and sorting device suitable for weighing and sorting articles, particularly seafood such as scallops and shrimp, one by one.

0002

[Prior art and its problems] Recently, it has become common practice to sort seafood such as scallops and shrimp by weight one by one, pack a certain number of boxes of each class of seafood, and ship them. However, in order to weigh such seafood one by one, conventionally, a weighing mechanism is installed below the upper running part of the belt conveyor, and the weight is measured one by one on the upper running part of the belt. Scallops to be weighed, for example, are transported, and during this belt-shaped transport, the weight is measured by a weighing mechanism installed below, and the weight is transferred from this weighing belt conveyor to the next process belt conveyor. A gate plate is provided that is driven according to the measurement result of the weighing mechanism, and this gate plate selectively rotates around its fulcrum according to the measurement result of the upstream weighing mechanism. There are known devices that can be sorted by rotating or not rotating. However, with such a device, some seafood may roll easily and may roll on the weighing belt conveyor and fall outward. In other words, there are restrictions on the properties and shape of the object to be weighed. In addition, the weighing mechanism, such as the load cell, is located below the upper running part of the belt, so its structure is complicated.Also, since the items handled are seafood, it must be cleaned frequently; The drive system and weighing mechanism are located on the back side of the machine, and cleaning them is difficult in order to prevent them from getting wet. Related to this is poor maintenance.

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

[0004] FIG. 20 shows a conventional transport device using a bucket conveyor, in which a bucket is attached between a pair of chains, and these chains circulate horizontal and vertical transport.

In this conveying device 1, gear devices 4, 5, 6, and 7 are supported within a rectangular frame 3 formed by an angle 2. As shown in FIG. Rotational force from a motor (not shown) is transmitted to a pulley 8 provided on 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 consists of a pair of two-strand chains 10 and 11.
A pair of shaft locking portions 12, 12 and 13, 13 are provided on the chain chains 10, 11 at predetermined intervals. On the inner side of these two-strand chains 10, 11, plates 14, 15 are arranged adjacent to the chains, respectively.

On the other hand, the bucket 16 is open on one side and has a substantially trapezoidal cross section, and each end of both side walls 16a and 16b, which are arranged parallel to the two-strand chains 10 and 11, has a shaft-mounting shaft. bosses 17a, 17b, 17c, and 17d are formed.

Bucket 16 in which such a boss is formed
20 and 21, the transport direction A is indicated by the arrow in FIGS.
On the other hand, a long shaft 18 is inserted through the bosses 17b and 17d on the front side, and both ends of the long shaft 18 are passed through the two-strand chains 10 and 11 and are locked in the shaft locking parts 12 and 13, respectively. ing. On the other hand, the boss 17a on the rear side with respect to the conveyance 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 manner, the buckets 16 are successively set on the pedestal 3 at predetermined intervals. When transporting items by a series of buckets 16 set on the pedestal 3,
The articles are sequentially placed into the horizontal bucket 16 from a position above the pedestal 3. By arranging the ends 14a and 15a of the plates 14 and 15 at the place where the items are accumulated, the short axis 1 of the bucket 16 passing through the ends 14a and 15a of the plates 14 and 15 is
9 is removed from the plates 14 and 15, the bucket 16 is rotated about the other long axis 18, and the stored items are dropped downward.

By the way, in such a transport device using a bucket conveyor, after the transport is completed, the empty bucket 1 is
6 then travels on the lower transfer path of the frame 3 while being suspended by the long axis 18, further moves upward in the vertical direction, and near the end of the upward movement, the short axis is placed on the plates 14 and 15 by appropriate means. 19
is reset.

Therefore, in the conventional bucket conveyor, the attitude in which the bucket 16 moves vertically is a suspended attitude with the opening facing in the horizontal direction, and items cannot be thrown into the part where the bucket 16 moves in this attitude. . Therefore, there is a limit to the work space etc. in which the bucket conveyor can be used. Further, in the above-mentioned conveyance device, the short axis 19 is connected to the plates 14 and 15.
In order to slide on the sliding portion, a means for lubricating the sliding portion is required, thus making the device complicated. Furthermore, if the hydraulic oil used in this lubricating means adheres to the inside of the bucket, there is a problem in that the commercial value of the transported items is impaired.

Furthermore, in the conventional bucket conveyor as shown in FIGS. 20 and 21, articles can only be placed into the bucket 16 through the horizontal transfer path as described above, but this It is conceivable that the pieces are weighed and put in one by one by a weighing mechanism, and then sorted according to the weighed value downstream from the put-in position. As mentioned above, the ends 14a of the plates 14, 15
, 15a, all the buckets 16 are now
As shown in , when one of the supports is removed,
It rotates around the rear shafts 12 and 13 and drops the items downward, but it is impossible with this conventional bucket conveyor to sort and rotate the items according to the weight results. be.

[0013]

[Problems to be Solved by the Invention] The present invention has been made in view of the above-mentioned problems, and is capable of reliably measuring the weight of each item, even for seafood such as scallops and shrimp. After reliably weighing, it is sorted according to the weighing results, making it easy to maintain, diversifying the work space, etc., and eliminating the need for complicated reset means before moving to the horizontal transfer path. The purpose of this product is to provide a weighing and sorting device for items that does not reduce product value due to adhesion of lubricating oil, etc.

[0014]

[Means for Solving the Problems] The above object has a substantially triangular cross section, is rotatably supported by a pair of chains on both side walls thereof, and in this suspended state, the front wall and A vertical chain conveyor comprising a plurality of buckets at a predetermined pitch, each of which has a rear wall that slopes upward, and has a guide piece attached to at least one of the two side walls that extends substantially vertically in a suspended state. The article is discharged one by one by the article weighing mechanism into the bucket running on the transfer path, and the guide piece is guided by a vertical guide member provided along the vertical transfer path to approach the horizontal transfer path. At least one actuator, which is disposed in a manner to be The bucket rotates around the support shaft to cause the stored items to fall downward, and the actuator is not driven and the bucket, which travels downstream, is moved to a horizontal transfer path section further downstream. The article weighing mechanism engages with an engaging member disposed close to the member and rotates around the spindle to cause the stored article to fall downward. V-shaped first plates are arranged at intervals, these first plates form an article receiving section for receiving articles supplied from above, and a weighing machine is mounted on a stationary part above the article receiving section. the first plate material is fixed to the lower end side of the load member hanging from the load part of the weighing machine;
A plurality of substantially rectangular second plates arranged so as to be able to pass through each interval of the plates in the vertical direction are fixed to a connecting rod of a lever crank mechanism, and the second plates are rotated by rotation of the crank of the lever crank mechanism. During that process, the second
When the plate material passes through the gap, the article weighed by the weighing machine in the article receiving section is pressed by the short side of the second plate material to be discharged from the article receiving section. This is achieved by weighing and sorting equipment.

[0015]

[Operation] The bucket is rotatably supported by a spindle,
Since the opening always faces upward in the suspended state, items can be loaded even in the vertical transfer path, and the loaded items are stored in the space defined by the front and rear walls. be done. Since the guide piece abuts and is guided by the vertical guide member when the article is loaded in the vertical transfer path, the article will not fall due to rocking. The stored items can be removed from the bucket by simply rotating the bucket around the support shaft, and can be easily removed by engagement between the engaging member and the guide piece.

In the article weighing mechanism, a plurality of first plates are arranged at intervals, and articles, such as scallops, are fed from above to the article receiving portion formed by the first plates. As a result, the weight of the scallops currently being received can be weighed via the first plate with a weighing machine connected to the first plate. The water adhering to the scallops drips downward through the gaps between the first plates. On the other hand, the second plate is driven by the lever crank mechanism to perform a predetermined closed loop movement through the gaps between the plurality of first plates, and as it passes through the gaps between the first plates, the weighed item is When moving the article in a predetermined stroke while pressing the article in the receiving section, the article can be discharged from the article receiving section and supplied to the bucket. Thereafter, the plurality of second plates move according to a predetermined path, and as they pass through the gaps between the plurality of first plates again, they support the weighed items that have already been fed from above in the same manner as described above, and carry out the next load. It can be discharged into a bucket.

[0017] As described above, it is possible to efficiently weigh items such as scallops and shrimp one by one and smoothly discharge them into the bucket. In addition, the shape of the product receiver can be made according to the product to be weighed. For example, if it is a belt type, it is not suitable to use a belt type that easily rolls, but depending on the shape of the product receiver of the first plate, Seafood of any shape can be reliably weighed and then smoothly discharged into a bucket.

[0018] Furthermore, since a weighing machine for weighing the items received in the item receiving part is disposed above the item receiving part, water can be sprayed from above the first and second plates during cleaning. It can be easily cleaned without any negative effect on the weighing machine, for example the load cell. In addition, since the fixed item receiver can receive and weigh items in a stationary state, it is possible to weigh items stably and accurately, and the items can be quickly discharged into the bucket using the second plate. Can be done.

The rotation shaft 67 is rotatably supported by a fixed plate (not shown) that is disposed to hang down from the solenoid mounting member 59. A substantially L-shaped hook portion 70 with a notch 69 and a rod portion 71 extending downward from the hook portion 70 are formed at the tip of the long arm portion 68 of the engagement member 66 . Further, the connecting portion 72 has a built-in torsion coil spring.

In the engagement member 66 formed in this way, 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 inserted into the small hole 60. The solenoid mounting member 59 is inserted into the hole 61 of the solenoid mounting member 59 . Even if an external force is applied to the long side arm portion 68 to rotate it counterclockwise around the rotation axis 67 in FIG. 9, when the force is released, the torsion coil spring spring The force causes it to move back clockwise, returning the torsion coil spring to its natural state.

Next, a scallop weighing and discharging mechanism according to an embodiment of the present invention will be described with reference to FIGS. 11 to 19.

In FIGS. 11 and 12, the lever crank mechanisms 91 and 91' are arranged symmetrically and have the same configuration, so only one lever crank mechanism 91 will be described.

[0036] This forms a so-called four-bar rotation mechanism, with four
It consists of links of books, one of which has a fixed structure. That is, a bearing box 92 is disposed on the base 105, and a shaft 94 fitted into the inner ring of this bearing extends to the other lever crank mechanism 91', thereby integrating them. The shaft 98 fixed to the inner ring of the other bearing box 93 is also shown in FIG.
As shown in , it is connected to the other lever crank mechanism 91'. Note that the inner ring of the bearing box 93 is coaxial with the pulley 28 in the figure.

A lower end portion of a lever lever 95 is connected to the shaft 94 so as to be rotatable therewith, and the upper end portion of the lever lever 95 is connected to a lever 97 as a connecting rod by a bearing 96 as a pivot point.
A crank plate 99 is rotatably attached to the shaft 98 of the other bearing box 93 at its lower end, and the inner ring side of the bearing box 100 is fixed to its upper end. The outer ring side is fixed to the above-mentioned lever 97 at the upper end of the bearing box 100 with a bolt 102. Also, a rotating shaft 10 fixed to the inner ring side of the bearing box 100
1 is fixed to a crank plate 99. With this configuration, the shaft 98 is rotated clockwise by the drive of the chain belt 30 wrapped around the pulley of the motor 27 in FIG. It is supposed to be done.

As described above, the lever crank mechanism 91
is configured, but the other lever crank mechanism 91
' is also symmetrical, so it is constructed in the same way. A connecting plate 103 is fixed to the left end of the lever 97, and this is connected to one end of the connecting rod 97' of the other lever crank mechanism 91, which corresponds to the lever 97 in FIG. 11, as shown in FIG. The levers 97, 97' of the lever crank mechanisms 91, 91' are arranged to move in the same manner in synchronization.

As shown in FIG. 11, the connecting plate 103 includes three discharge plates 114 serving as second plate members each having a substantially rectangular shape, and three spacers 1 as shown in FIG. 12 in this embodiment.
10, and are fixed at a predetermined pitch. That is, these discharge plates 114 perform the same movement as the lever 97. In addition, so that these discharge plates 114 can pass through the gaps S between them, a spacer block 112 is also interposed between them so that a weight plate 107 as a first plate material having an approximately ladle shape is attached to the shaft as shown in FIG. 108, 10
9 are fixed in common, and these shafts 108, 10
Both ends of the load cell 9 are fixed to weight connecting plates 106a and 106b hanging down from the load cell 111. The load cell 111 is fixed to the upper stationary part S' and is formed by a known Roberval mechanism, so that the load cell 111 vertically moves the weight connecting plate 10
6a and 106b. As described above, the weighing plate 107 has a substantially ladle shape, and due to this shape, these three plates constitute an article receiving portion T having a substantially V-shaped cross section. As shown above, for example, a scallop M can be received. In addition, the discharge plate 114 in this embodiment is made up of three plates, and these operate as will be described later.A chain supply conveyor 78 is provided on the left side of these plates, as shown by the arrows. to 1
The structure is such that the scallops M are supplied one by one, and by the operation of the discharge plate 114 as described later, the scallops M received in the product receiving part T are removed as shown by arrow a during the movement of the discharge plate 114. , and is supplied to the bucket 35 being transferred by the vertical transfer section of the bucket conveyor 32 disposed to the right.

In FIGS. 1 and 2, the article weighing mechanism 9
On the upstream side of 0, scallop chain supply conveyors 78 each having a large number of connected elements each having a V-shaped cross section are arranged in four rows in this embodiment, as shown in FIG. and,
Only the drive chain gear 79 is shown in this figure, which receives the drive force of a pulley 81 via a chain belt 80'. The pulley 81 is attached to a frame 82 fixed to a pedestal, and is wound around the pulley of the motor 27, which is the drive source, via a chain belt 83. Therefore, the scallop chain supply conveyor 78 is driven at a predetermined timing and the transfer speed of the bucket conveyor 32 according to the diameter ratio and number of teeth of the pulley 81 and the drive chain gear 79.

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

[0042] Now, the motor 27 is driven, and the gear device 23
5 rows of two-strand chain 33, 33, 33, 33, 33
Power is transmitted to other gear devices 24, 25, and 26 via. Accordingly, four rows of bucket conveyors are supported between the two double-strand chains 33, 33 and are transported within the apparatus 20 in the direction of arrow B in FIGS. 1 and 2. 8
The electromagnetic solenoids 64, 64, . . . , 64 are all in a non-energized state, and the corresponding engaging members 66 are also all in the upper position. On the other hand, weighing mechanism 9 for scallop scallops etc.
0 is weighed to 1 piece. Then, the weighed scallops and the like are supplied one by one into a bucket 35 that is conveyed through a vertical transfer path section between the gear device 26 and the gear device 23 in the device 20. In this vertical transfer path, the bucket 35 is moved to the curved portions 37a and 37b of the guide piece 37, as shown in FIG.
is in contact with the vertical guide member 55, which guides the vertical movement, so that the posture is maintained constant. That is, even if an item such as a scallop is thrown into the bucket 35 in the vertical transfer path, the bucket 35 will not swing. In the embodiment, the scallops etc. put into the bucket 35 are sorted into eight groups by weight, and the group to which the scallops etc. belong is input into the controller 200 after weighing. The weighed scallops and the like are then sorted by weight by this device 20 and stored in groups in the lower container.The sorting operation will be explained below.

Groups based on weight correspond to any electromagnetic solenoid. After storing the scallops etc. in the bucket, the travel distance of the two-strand chain 33 until it reaches the corresponding electromagnetic solenoid is calculated by a pulse encoder etc., and after a predetermined time, the corresponding electromagnetic solenoid 64 is energized 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 is in the illustrated state, and the rod portion 71 is disposed in front of the rear wall portion 35d of the desired bucket 35 that is about to pass directly below. Therefore, the bucket 35 travels with the rear wall portion 35d in contact with the rod portion 71 of the engaging member 66, so the bucket 35 rotates counterclockwise around the shafts 51 and 54 in FIG. As a result, the stored scallop scallops fall to appropriate positions in the lower collecting chute 76 and are stored in the container.

[0044] Thereafter, a predetermined electromagnetic solenoid is similarly energized for the following buckets, and the scallops pass through the chute and are stored in containers classified by weight. Therefore, scallop scallops are sorted by weight within a predetermined range and stored in a container or the like.

[0045] When the bucket 35 finishes transporting the contents, the front wall part 35c and the rear wall part 35d return to the upward slope due to their own weight, and from the remaining horizontal transfer path section downward the vertical transfer path section and the After traveling along the lower horizontal transfer path section, the posture is maintained by the guide piece 37 again, and the vehicle is transferred along the vertical transfer path section between the gear device 26 and the gear device 23.

The bucket conveyor according to the embodiment of the present invention operates as described above, and has the following effects. That is, when transporting marine products, regular cleaning is performed for hygiene reasons, and since the electric electromagnetic solenoid 64 is located above the device, cleaning with water or the like is easy. Furthermore, the processing capacity can be freely set by adjusting the rotational force of the motor 27, the number of bucket conveyors arranged, etc.

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

The lever crank mechanisms 91, 91' are constructed as described above, and when the shaft 98 is rotated at a constant speed, the shaft 1 fixed to the crank plate 99 is rotated.
01 rotates at a constant speed along a trajectory C. When this shaft 101 is rotated by 45 degrees from the phase shown in FIG. 11, it assumes the position shown in FIG. 13. The lever 95 swings through an angle about the axis 94 from the position shown in FIG. A lever 97, via a shaft 96 connected thereto, assumes the position shown in FIG. 13, and therefore a discharge plate 110 fixed to its left end also assumes the position shown. Further rotation by 45 degrees from now on, that is, rotation by 90 degrees from the phase in FIG. 11, takes the position shown in FIG. 14, the lever 95 further swings to the right around the shaft 94, and the lever 97 moves to the right. At the same time, its left end portion moves downward. Therefore, the discharge plate 110 fixed to this end assumes the position shown.

When the lever 95 is further rotated by 45 degrees, it assumes the position shown in FIG. 15, and in this phase, the lever 95 changes its direction of movement to the left and swings. At the same time, the lever 97 moves to the left, but the left end falls further downward, and the discharge plate 110 fixed thereto also assumes a downward position. Further rotation of 45 degrees from now on, that is, rotation of 180 degrees from the rotational phase of FIG. 11, takes the position shown in FIG. The lever 97 that has been moved also moves to the left, and the discharge plate 110 fixed to the left end of the lever 97 also falls further downward. When the lever 95 is further rotated by 45 degrees, it assumes the position shown in FIG. begins to rise upwards. When rotated further 45 degrees, it assumes the position shown in Figure 18, and the lever 95
moves slightly to the left around axis 94. This causes the discharge plate 110 to assume the position shown. When the lever 95 is further rotated by 45 degrees, it assumes the position shown in FIG. Moving. Therefore, the discharge plate 110 also moves significantly accordingly. When the lever 95 is further rotated by 45 degrees, the lever 95 swings significantly to the right around the shaft 94, and along with this, the lever 97 also moves to the right, and its left end portion moves significantly upward. Therefore, the initial rotation phase shown in FIG. 11 is taken.

As described above, due to the constant rotational movement of the shaft 93, the crank plate 99 fixed thereto moves along the path shown by the trajectory C. 114 is carried out, and during such a process, the rotation phase as shown in FIG. One scallop M is supplied from the left chain supply conveyor 78, and this is
It is placed as shown in FIG. Therefore, these three weighing plates 107 are integrated, and their ends are connected to a pair of weighing connecting plates 106a and 106b extending upward, so that they are not connected to their upper ends. At this time, the weight of the scallop M placed on the product receiving portion T is measured by the load cell 111 located therein. Next, the discharge plate 112
The scallop M moves along the above-mentioned trajectory, and the weighed scallop M in the article receiving section T moves along the short edge 114a of the discharge plate 114 in the rotational phase between the rotational phases shown in FIGS. 18 and 19.
The scallop M received in the receiving portion T is pushed out as shown in FIGS. 11 and 19. Therefore, as shown in FIG. 11, the vertical portion of the bucket conveyor 32 disposed on the right side is dropped and supplied to one of the buckets 35 that is being transported, as shown by 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, but during this process, the next scallop M is already supplied from the chain supply conveyor 78 to the product receiving part T, and as described above, However, the timing at which the scallops are supplied from the chain supply conveyor 78 can be set to a rotational phase as shown in FIG. can. That is, the long edge 114b of the discharge plate 114, which is in the rotational phase shown in FIG. The weight of this scallop M can be stably measured by the load cell 111 when it is placed on the product receiving part T of the weighing plate 107, and as the rotation phase further advances, the weight of the scallop M can be weighed stably by the load cell 111.
The scallops M are pushed out by the short edge 114a of the bucket 35 and are supplied to the next bucket 35.

Note that the bucket 35 of the bucket conveyor 32
The movement timing coincides with the supply timing of the scallops M, which are supplied one by one from the chain supply conveyor 78, so that the next bucket 35 is surely in the position to receive the next scallop.

Although the discharge plates in other rows have not been explained above, in this embodiment, a plurality of rows are provided as described above, and the same functions are performed. Furthermore, since these rows are operated synchronously, if four rows are provided as in the embodiment, four scallops M can be weighed at the same time, and each bucket 35 of the bucket conveyor 32 installed in parallel can be weighed. It can be supplied falling at the same time.

The article weighing and sorting device equipped with buckets according to the embodiment of the present invention has been described above, but of course,
The present invention is not limited to the above-mentioned 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 protruding from the side walls 35a, 35b of the bucket 35, but these shafts are made into one, and both side walls 35a, 3 of the bucket 35 are supported rotatably.
It may be passed between 5b.

Further, in the above embodiment, the front wall 35c and the rear wall 35d of the bucket 35 are formed into a flat plate shape, but as in the bucket 77 shown in FIG. A plurality of continuous slits 80 may be formed over 77d. By providing the slit 80 in this manner, moisture etc. adhering to the stored items can be removed from the bottom during transport, and items that tend to adhere to the inner wall of the bucket 35, such as cod roe, can be removed from the bottom. Makes it easier to drop. Also, if it extends to the center of the bottom of the bucket 77,
The slit 80 may be formed only in the front wall portion 77c. Furthermore, by forming the slits, the weight is reduced, so the load on the motor can be reduced.

Further, in the above embodiments, the present invention was applied to a transportation device for marine products, but it is of course applicable to other products, such as agricultural products such as chestnuts.

Furthermore, in the above embodiment, the bucket conveyor was constructed in four rows as shown in FIG. It can be changed.

Furthermore, in the above embodiments, a plurality of rows, that is, four rows of bucket conveyors were explained, and scallops were explained as the seafood to be weighed, but of course, other small seafoods and shrimps , scallops, etc. Alternatively, other items may be used instead of seafood.

In addition, in the above embodiment, the lever crank mechanism was explained as a four-joint rotation mechanism, but the levers 95, 97, 99 constituting each link are attached to the discharge plate 104 fixed to the lever 97 as desired. The length can be selected depending on the movement to be performed, and the relative shape of the weight plate 107 and the discharge plate 114 that move with the rotation of the shaft 98, or the desired relative position of the discharge plate 114 with respect to the weight plate 107. It may be selected as appropriate depending on the state of change.

Further, the shape of the discharge plate 114 is not limited to that shown in the drawings, and the mounting position of the discharge plate 114 is also not limited to that shown in the figure.
The discharge plate 114 does not have to be attached to the left end of the lever 7, but may be attached to another part.In short, the discharge plate 114 moves in accordance with the movement of the lever 97 of the lever crank mechanism 1. What is necessary is to perform the following actions.

Therefore, in the above-mentioned embodiments, the long edge of the mounting plate 110 has been described to have a soft landing on the article receiving portion T, but of course the chain supply conveyor may be placed directly on the article receiving portion T without being received on the long edge. Even if it is supplied by dropping from 78, if the falling height is small, it will not be any problem in weighing.

Furthermore, in the above embodiment, the electromagnetic solenoid 64
Although eight pieces are provided in the upper horizontal transfer path section, it is not necessary to provide this many pieces, but one piece may be provided on the upstream side, and a fixed engagement member may be provided on the downstream side. In this case, one electromagnetic solenoid 64 includes an article weighing mechanism 90.
By comparing the result weighed by the load cell 111 with the set value, a certain weight m whose weight value is between a and b is determined.
If so, by energizing this one electromagnetic solenoid 64, when the bucket 35 containing this item reaches this downward position, it will be energized and the engaging member will rotate the bucket 35 to move the scallop downward. The buckets containing scallops of other weights are guided directly to the downstream side, and the fixed engagement member on the downstream side
All of them may be tilted and discharged downward. As described above, the scallops are placed in a predetermined weight range, i.e., a and b.
It can be divided into weights between and weights other than that.

[0064]

As described above, according to the article weighing and sorting device of the present invention, regardless of the shape of the article to be weighed or discharged, the weight of the article can be reliably received and weighed. can be weighed, and can be smoothly discharged or fed into a bucket.

[0065] Since the load cell as a weighing mechanism is disposed above, when cleaning with water for maintenance, water is sprayed onto the article receiving part T from below the load cell, and the weighing plate and discharge plate are Its maintenance work is easy as it can be cleaned and the load cell is not sprayed with any water. Of course, as shown in the figure, the motor for rotating the shaft can transmit rotational force from a motor disposed far away by means of a chain belt, so there is no need to worry about water being sprayed against the drive unit. In addition, there is no need for any reset means to change the attitude of the bucket to receive items, which simplifies the overall structure.Also, since there are no sliding parts when transporting the bucket, the hydraulic oil of the lubrication means is There is no fear that the product will adhere to the product, and the product can always be transported in good condition.
