DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guide chute apparatus and, more particularly, to a guide chute apparatus for a bucket conveyor suitable for use in a weighing / sorting apparatus for weighing and sorting fish and shellfish such as scallops and shrimps 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. For example, scallop to be weighed is conveyed, and in the course of this conveyance , the weight is measured by a weighing mechanism provided below the scallop, and the weighing mechanism is transferred from the weighing belt conveyor to a belt conveyor in the next process. A gate plate is provided, which is driven according to the measurement result weighed by, and which is selectively rotated around its fulcrum according to the measurement result of the upstream weighing mechanism, Or sorting without rotating Those in so that is known.
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 nature and shape of the weighed object. Further, the weighing mechanism, for example, the load cell is disposed below the upper traveling portion of the belt, so that the structure is complicated, and since the articles to be handled are fish and shellfish, the cleaning must be performed frequently. There is a drive system and a weighing mechanism on the back side of the, and it is difficult to clean them 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. 32 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.

As shown in FIG. 33, the conveying means 9 comprises a pair of two-chain chains 10 and 11.
The chain chains 10, 11 are provided with a pair of shaft locking portions 12, 12, 13, 13 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.

The bucket 16 having such a boss is 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. By arranging the ends 14a and 15a of the plates 14 and 15 at a place where goods are collected, the short axis 1 of the bucket 16 passing therethrough is arranged.
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. 32 and 33, articles can be put into the bucket 16 only through 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 by 3, when one of the supports is lost, the product is rotated around the long axis 18 to drop the article downward. Is not possible with this conventional bucket conveyor.

The outer ring is fixed to the above-mentioned lever 97 by a bolt 102 at the upper end of the bearing box 100. A rotating shaft 10 fixed to the inner ring side of the bearing box 100
1 is fixed to the crank plate 99. With such a configuration, the shaft 98 is rotated clockwise by the drive of the chain belt 30 wound around the pulley of the motor 27 in FIG. 13 , and the crank plate 99 rotates with the rotation as shown by the locus C ′. Is to be performed.

As described above, the lever crank mechanism 91
The other lever crank mechanism 9
1 'is also symmetrical, so it is similarly configured. The left end portion of the lever 97 and the connecting plate 103 is fixed, which is coupled as shown in FIG. 24 at one end of the 'connecting rod 97 corresponding to the lever 97 in FIG. 23 of the' other lever crank mechanism 91 The levers 97, 97 'of the lever crank mechanisms 91, 91' make the same movement in synchronization.

[0032] The connecting plate 103, as best seen in FIG. 23, the discharge plate 114 of the second plate member substantially rectangular in three schools respectively by interposing a spacer 110 as shown in FIG. 24 in this article sorting apparatus Are fixed at a predetermined pitch. That is, these discharge plates 114 are
Exercise similar to. Also these discharge plate 114, as can pass through the gap S ₂ between each, as shown in FIG. 23 also by interposing a spacer block 112,
The weighing plate 107 serving as a first plate material having a substantially ladle shape has a shaft 10
8 and 109, and these shafts 10
Both ends of 8 and 109 are fixed to weighing connecting plates 106 a and 106 b which are suspended from the load cell 111. The load cell 111 is fixed to the upper stationary part S ₂ ′ , and is constituted by a known Roberval mechanism, and is configured to receive a force applied to the weighing connection plates 106 a and 106 b in the vertical direction. The weighing plate 107 has a substantially ladle shape as described above.
An article receiving portion T having a substantially V-shaped cross section is constituted by the school board. As shown above, for example, scallops M are received. The discharge plate 114 is also formed of three schools in the present product sorting apparatus, and they operate as described later. A chain supply conveyor 78 is provided on the left side of the discharge plate 114. The scallops M are supplied one by one as described above, and the scallops M received by the goods receiving portion T by the operation of the ejection plate 114 described later are indicated by arrows a during the stroke of the ejection plate 114. As shown in the figure, the bucket 35 is supplied to the bucket 35 being transferred by the vertical transfer section of the bucket conveyor 32 disposed on the right side.

13 and 14, on the upstream side of the goods weighing mechanism 90, a scallop chain supply conveyor 78 formed by connecting a number of elements having a V-shaped cross section is connected.
As shown in FIG. 4, the product sorting apparatus is arranged in four rows. Although only the drive chain gear 79 is shown in FIG. 13 , it receives the driving force of the pulley 81 via the chain belt 80 '. The pulley 81 is attached to a frame 82 fixed to a gantry. The pulley 81 is wound around a pulley of the motor 27 as a driving source described above via a chain belt 83. Therefore, the scallop chain supply conveyor 78 includes the pulley 81, the drive chain gear 7
The bucket conveyor 32 is driven at a predetermined speed with the transfer speed of the bucket conveyor 32 in accordance with the diameter ratio of 9 and the number of teeth.

The product sorting apparatus 20 is configured 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 taraco. 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 train 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. Therefore, supported by the two double-row chains 33, 33, four rows of bucket conveyors are transported in the apparatus 20 in the direction of arrow B in FIGS. The eight electromagnetic solenoids 64, 64...
All are in the non-excited state, and the corresponding engaging members 66 are all in the upper position. On the other hand, the scallops of the scallops are weighed one by one by the weighing mechanism 90. The weighed scallop and the like are stored in the gear device 26 and the gear device 23 in the device 20.
Are supplied to the bucket 35 which is transporting the vertical transfer path between them. Bucket 3 in this vertical transfer path
5 is a curved portion 37 of the guide piece 37 as shown in FIG.
Since a and 37b abut on 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 bucket 35 is used.
The scallops and the like thrown into the inside are classified into eight groups by the weight, and to which group the stalks and the like belong is input to the controller 150 after the weighing. 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 one of the electromagnetic solenoids 64 . 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 64 is calculated by a pulse encoder or the like, and after a predetermined time, the corresponding electromagnetic solenoid 64
Are excited for a predetermined time. When the electromagnetic solenoid 64 is excited, the actuator 65 and the engaging member 66 in FIG. 22 are in the illustrated state, and the rod portion 71 is disposed in front of the guide piece 37 of the desired bucket 35 to pass immediately below. Is done. Therefore, the bucket 35
Since the travel by contacting the guide piece 37 to the rod portion 71 of the engaging member 66, the bucket 35 is rotated counterclockwise around the shaft 51, 54 in FIG. 22, thereby,
The contained scallop scallop is the lower collecting chute 7
6 falls to an appropriate position and is stored in a container.

Thereafter, similarly, in the subsequent bucket, a predetermined electromagnetic solenoid is excited, and the scallop passes through the chute and is stored in a container according to weight. Therefore, the scallops of the scallops are sorted by weight within a predetermined range and stored in a container or the like.

When the bucket 35 has finished transporting the contents, the front wall 35c and the rear wall 35d return to their upward inclinations due to their own weight, and the vertical transfer path from the remaining horizontal transfer path to the lower part, and After traveling on the lower horizontal transfer path portion, the posture is again held by the guide piece 37, and is transferred on the vertical transfer path portion between the gear device 26 and the gear device 23.

The lever crank mechanisms 91 and 91 'are configured as described above. When the shaft 98 is rotated at a constant speed, the shaft 1 fixed to the crank plate 99 is thereby rotated.
01 rotates at a constant speed along the locus C ′ . The shaft 101 takes the position shown in FIG. 25 rotates 45 degrees from the phase shown in FIG. 23. Leverage lever 95 about the axis 94 from the position of FIG. 23, to an angle swing. The lever 97 takes the position shown in FIG. 25 via the shaft 96 connected thereto, so that the discharge plate 114 fixed to the left end also takes the position shown. With further rotation now 45 degrees, i.e., from the phase of Fig. 23 is rotated 90 degrees FIG. 26
It takes the position shown in, leverage lever 95 is further swung to the right about the axis 94, the lever 97 is the left end as well as moved to the right to move downward. Therefore, the discharge plate 114 fixed to this end takes the position shown in the figure.

[0040] Further taking the position shown in FIG. 27 rotates 45 degrees, the lever lever 95 in this phase change the moving direction and leftward swings. At the same time, the lever 97 moves to the left, but the left end further falls downward, and the discharge plate 114 fixed thereto also assumes the position of falling downward. When further rotated from now 45 degrees, i.e. rotated 180 degrees from the rotational phase of Fig. 23 takes the position shown in FIG. 28, the lever lever 95 in this phase is swung to the left about the axis 94, thus pivoting to Lever 97 wearing
Also moves to the left, and the discharge plate 114 fixed to the left end falls further downward. When rotated further 45 degrees, the lever shown in FIG. 29 assumes the position shown in FIG. 29 , and the lever 95 swings further to the left around the shaft 94, so that the lever 97 connected thereto also swings to the left. It begins to rise slightly upwards. When further rotated 45 degrees taking the position shown in FIG. 30, the lever lever 95 is moved slightly to the left about the axis 94. As a result, the discharge plate 114 assumes the illustrated position. When further rotated 45 degrees taking the position shown in FIG. 31, thereby around a turn shaft 94, lever lever 95
Swings greatly, and by this movement, the lever 97 also largely moves rightward, and also largely moves upward. Accordingly, the discharge plate 114 also moves greatly in response to this. 4 more
When rotated five degrees , the lever 95 swings largely to the right around the shaft 94, and the lever 97 also moves to the right, and the left end of the lever 97 moves largely upward. Therefore, the initial rotational phase shown in FIG. 23 is taken.

As described above, the crank plate 99 fixed to the shaft 98 moves along the stroke indicated by the trajectory C ' by the constant-speed rotation of the shaft 98 , thereby discharging the above-described movement. although the plate 114 is performed, the rotation phase, as shown in Figure 26 during this process,
Or scallop M on the goods receiving T formed in the upper side portion of the weighing plate 107 of the first plate member in the stroke is supplied one more chain feed conveyor 78 of the left, which is 26
30 are placed as shown in FIG. Therefore, the weighing plates 107 of these three schools are integrated and connected to a pair of weighing connecting plates 106a and 106b extending upward at both ends, so that they are connected to their upper ends. 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. Then discharge plate 11
Although 4 is to move in the trajectory, as described above, scallop M is 30 in the weighing has been goods receiving T, short edge 114 of discharge plate 114 in the rotational phase between the rotational phase shown in FIG. 31
As shown in FIGS. 31 and 23 , the scallop M received by the receiving portion T is pushed out as shown in FIG. Accordingly, as shown in FIG. 23 , the vertical portion of the bucket conveyor 32 disposed 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 scallops M has been supplied to the bucket 35. During this process, the next scallops M have already been supplied from the chain supply conveyor 78 to the article receiving portion T, and as described above. 23 , the timing supplied from the chain supply conveyor 78 can be the rotation phase as shown in FIG. 23. In this case, the scallop M can be subjected to the so-called soft landing effect. it can. That undergoing scallops M from the chain feed conveyor 78 at the long edge 114b of the discharge plate 114 in the rotational phase shown in Figure 23, which although to descend gradually undergoing stroke as described above, thereby gently 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.

Although the discharge plates in other rows have not been described above, the product sorting apparatus is provided with a plurality of rows in the above-described configuration and performs the same operation. In addition, since these rows are operated in synchronization, if four rows are provided as in the present product sorting apparatus, the four scallops M are simultaneously weighed by four, and each of the bucket conveyors 32 arranged side by side is weighed. The bucket 35 can be simultaneously supplied by dropping.

As described above, articles in a predetermined weight range are discharged from the row of buckets 35 corresponding to the respective electromagnetic solenoids 64 to the guide chute 75 below the buckets 35, as shown in FIG. 34, the rightmost bucket conveyor row 121 in FIG.
There is no problem because the height of the articles falling from the guide chute 75 to the guide chute 75 is not so small, and the height rebounding from the guide chute 75 is not so large. In this row 121 , the container C ₉ (C ₁ to
C ₈ ) . However, since the articles falling from the fourth row of bucket conveyors 124 from the right fall on the guide chute 75 with a large head, some articles receive a large recoil force and jump outward from the guide chute 75, In some cases, an adjacent guide chute moves to a guide chute for receiving an item having another predetermined range of weight, and falls to a container for receiving an item having another predetermined range of weight. Bucket conveyor rows 122 , 1 of other rows
Similarly, the risk described above frequently occurs as the head becomes larger with respect to 23 .
