BACKGROUND OF THE INVENTION FIG. 11 shows a conventional bucket conveyor-based conveying device in which a bucket is attached between a pair of chains and the chains circulate horizontally and vertically.

In this conveying device 1, gear devices 4, 5, 6, and 7 are supported within a rectangular frame 3 formed by an angle 2. 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. 12, 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 having such a boss formed therein
In this case, the long shaft 18 is inserted through the bosses 17b and 17d on the front side with respect to the conveyance direction A shown by the arrow in FIGS. 11 and 12,
Both ends of the long shaft 18 are passed through the two-strand chains 10 and 11 and are respectively locked by the shaft locking portions 12 and 13. On the other hand, the bosses 17a, 17 on the rear side with respect to the conveyance direction A
A short shaft 19 is inserted through c, and both ends of the short shaft 19 are locked to 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 running part of the pedestal 3 suspended by the long axis 18, further moves upward 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 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, if the item has a large amount of moisture attached to it, the entire bucket becomes heavy, increasing the load on the driving source.

0010

[Problems to be Solved by the Invention] The present invention has been made in view of the above-mentioned problems, and even if the bucket conveyor is arranged vertically, the supply position of articles is not limited. In addition, there is no need to provide a complicated reset means before moving to the horizontal transfer path, and in addition, there is no need to damage the product value due to adhesion of lubricating oil, etc. Furthermore, there is no need to install a complicated reset means before moving to the horizontal transfer path. The purpose of the present invention is to provide a bucket for a bucket conveyor that does not increase the load on the drive source even when the load is on the drive source.

[0011]

[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 bucket conveyor characterized in that the rear wall portion is inclined upward, a plurality of slits are formed in parallel between both outer edges of both wall portions, and a protrusion is formed in parallel between each of these slits. This is achieved by a bucket in .

0012

[Operation] The bucket is rotatably supported by a spindle,
Since the opening always faces upward in the suspended state, items can be thrown in from any position, and the thrown items are stored in the space defined by the front wall and the rear wall. Ru. The stored items can be removed from the bucket by rotating the bucket around the spindle, and the items can be removed from any position. Furthermore, since moisture adhering to the items can be allowed to fall downward through the slits, the total weight of the bucket for transporting the items can be reduced, and the load on the drive source can therefore be reduced. Furthermore, when the bucket is tilted to discharge the articles, the protrusions allow for smooth discharge.

A predetermined number (eight in the embodiment) of electromagnetic solenoids 64 are accommodated in the space 63 defined by the solenoid mounting member 59, and these electromagnetic solenoids are attached to the bottom plate 59c of the mounting member 59 by screws. Fixed. Figure 1
As shown in FIG. 0, an engaging member 66 is attached to the actuator 65 of the electromagnetic solenoid 64. The engagement member 66 is formed into a substantially L-shape including a short side arm portion 73 and a long side arm portion 68, with a connecting portion 72 having a rotation shaft 67 as a boundary. 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. At the tip of the long side arm portion 68 of the engagement member 66,
A substantially L-shaped hook portion 70 having a notch 69 and a rod portion 71 extending downward from the hook portion 70 are formed. 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 about the rotation axis 67 in FIG. The force causes it to move back clockwise, returning the torsion coil spring to its natural state. Note that when the engagement member 66 rotates, one end 70a of the hook portion 70 and one end 71a of the rod portion 71 come into contact with the bottom plate 59c of the solenoid mounting member 59, thereby reducing the rotation range of the engagement member 66. Regulated.

When the electromagnetic solenoid 64 is energized from such a non-energized state, the actuator 65 is placed in the solid line position, and at the same time, the engaging member 66 is placed in the downward position as shown. At this time, the one end 70a of the hook part 70 comes into contact with the bottom plate 59c of the mounting member 59, but by pasting a cushioning material 58 such as urethane rubber on the part that comes into contact with the one end 70a of the hook part 70, it is possible to prevent damage caused by the collision. Sound generation is prevented. Similarly, if the cushioning material 74 is attached to the part where the engaging member 66 comes into contact with the one end 71a of the rod part 71 when it is in the upper position, abnormal noise caused by the collision at the time when the excitation is finished can be avoided. Occurrence can be prevented.

Below each electromagnetic solenoid 64 disposed at a predetermined position of the solenoid mounting member 59, there is a collection chute 76 partitioned into a plurality of parts by a partition plate 75.
are arranged, and each chute of the collection chute 76 corresponds to one of the upper electromagnetic solenoids 64. Containers and the like are placed below these chutes.

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

[0029] 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. Therefore, the four rows of bucket conveyors are supported between the two two-strand chains 33, 33, and the conveying device 20
1 and 2 in the direction of arrow B. The eight electromagnetic solenoids 64, 64, . . . , 64 are all in a non-energized state, and all the corresponding engaging members 66 are also in the upper position. On the other hand, scallops and other scallops are weighed individually using a weighing method not shown. Then, the weighed scallops and the like are supplied one by one into a bucket 35 that is conveyed through a vertical transfer section between the gear device 26 and the gear device 23 in the conveyance device 20. Bucket 35 in this vertical running part
As shown in FIG. 6, the curved portion 37a of the guide piece 37,
37b comes into contact with the vertical guide member 55, which guides the vertical movement, so that the posture is maintained constant. That is, even when an item such as a scallop is thrown into the bucket 35 from the vertical transfer section, the bucket 35 does not swing. In the embodiment, the scallops and the like put into the bucket 35 are sorted into eight groups by weight, and the group to which the scallops and the like belong is input into the controller after weighing. The weighed scallops and the like are then sorted by weight by this transport 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 66 in FIG. 10 are in the state shown in the figure, and the rod portion 71 is positioned in front of the rear wall portion 35d of the desired bucket 35 that is about to pass directly below. Placed. Therefore, since the bucket 35 travels with the rear wall portion 35d in contact with the rod portion 71 of the engagement member 66, the bucket 35 is driven by the shafts 51 and 5 in FIG.
4 in the counterclockwise direction, thereby the housed scallop scallops fall to an appropriate position in the lower collecting chute 76 and are housed in a container or the like.

[0031] Thereafter, a predetermined electromagnetic solenoid is similarly energized for the following buckets, and the scallops pass through the chute and are housed in containers classified by weight. Therefore, scallop scallops are sorted by weight within a predetermined range and stored in a container or the like.

When the bucket 35 finishes transporting the contents, the front wall portion 35c and the rear wall portion 35d return to the upwardly inclined position due to their own weight, and the remaining horizontal traveling portion downwards to the vertical traveling portion and the lower portion. After traveling through the horizontal traveling section, the posture is maintained by the guide piece 37 again, and the vehicle is transported through the vertical traveling section between the gear device 26 and the gear device 23.

The conveying device equipped with the bucket conveyor according to the embodiment of the present invention performs the above-mentioned functions, and has the following effects. In other words, when transporting seafood, etc., regular cleaning is performed for hygiene reasons.
Since the electrical electromagnetic solenoid 64 is located above the device, it is easy to clean with water or the like. Furthermore, the processing capacity can be freely set by adjusting the rotational force of the motor 27, the number of bucket conveyors arranged, etc.

[0034]Also, in the above embodiment, the product, that is, the scallop scallops, was introduced into the vertical running part of the bucket conveyor, but it is also possible to throw them into the horizontal running part above, and the charging position can be set as appropriate. can do.

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 the scallops. However, since the front wall portion 35c and the rear wall portion 35d are inclined upward, no complicated reset means is required.

Furthermore, since the bucket 35 is formed with a plurality of slits S, water adhering to the items drips downward from the slits S, thereby reducing the overall weight of the bucket 35 during transportation, and thus reducing the driving speed. The load can also be reduced. Furthermore, even when washing by spraying water from above, water does not accumulate at the bottom.

Furthermore, since the ribs R are provided, some items can be prevented from getting caught in the slit S, and the frictional force can be reduced so that they can be smoothly discharged downward.

Although the conveyance device equipped with a bucket according to an embodiment of the present invention has been described above, the present invention is of course not limited to the above embodiment, and various modifications can be made based on the technical idea of the present invention. It is.

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.

Furthermore, in the above embodiments, the present invention was applied to a transportation device for marine products, but it can of course be applied 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.

[0042]

Effects of the Invention As explained above, according to the bucket in the bucket conveyor according to the present invention, articles can be thrown in even if the bucket is in the horizontal traveling section or the vertical traveling section, so that the bucket conveyor can be used. You can diversify your work space. In addition, no reset means is required to change the attitude of the bucket to receive items.
The overall structure can be simplified, and since there are no sliding parts when transporting the bucket, there is no risk of the hydraulic oil of the lubricating means adhering to the goods, and the goods can always be transported in good condition. Can be done. Furthermore, water adhering to the item can be allowed to fall downward through the slit,
The weight of the entire bucket is reduced to reduce the driving load, and
It is also easy to wash with water. Furthermore, since the protrusion is provided, it is possible to prevent some items from getting caught in the slit S, and to reduce the frictional force so that they can be smoothly discharged downward.
