BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bucket in a bucket conveyor, and more particularly, to a bucket in a bucket conveyor in which a chain conveyor is arranged vertically.

0002

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 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. In addition, in order to be able to load items into the bucket 16 from the vertical transfer path, for example, the bucket is supported by a single shaft at an intermediate position in the width direction, and the bucket is prevented from rotating easily. It is conceivable to use a bucket that is longer in the vertical direction than in the width direction in consideration of stability against rotation of the center of gravity, but in this case, there is a problem that the bucket becomes larger. As the bucket becomes larger, there is a problem in that the function for discharging items from the bucket also becomes larger. Further, in the above-mentioned conveyance device, since the short shaft 19 slides on the plates 14 and 15, a means for lubricating this sliding portion is required, which makes 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. In addition, when this bucket conveyor is constructed in a multiple series type, sliding means by the plates 14 and 15, reset means, and lubricating means must be installed on the pedestal 3 in correspondence with the number of the multiple series. The structure became complicated, making it difficult to increase processing capacity. 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. Furthermore, if the item has a property that it tends to stick to its surroundings, it will get caught in the bucket and there is a problem that the item will not be ejected.

[0010] On the other hand, there is also known a conveying device that conveys items such as foods using an endless belt.

[0011] Conveying device 100 shown in FIGS. 13 and 14
In this case, two endless belts 103 and 104 which are driven in circulation by a motor 102 are arranged in a storage section 101 that stores a large amount of foods such as seafood, and the seafood etc. are continuously distributed on the conveying surface of these endless belts. It is latched by conveyor plates 105, 105 each having a V-shaped cross section, and rises in an oblique direction. Marine products and the like transported to the upper position by the endless belts 103 and 104 are supplied onto the endless belts 122 and 123 circulating in the horizontal direction at this upper position. Weighing machines 124 and 125 are disposed below the endless belts 122 and 123, and the weight of the articles is weighed as they are transported by the endless belts 122 and 123, respectively. The weighing results are sent to the control unit 1.
The weighed items stored in 06 are further supplied to a downstream endless belt 107 which is wider and circulates in the horizontal direction. As shown in FIG. 15, in the conveyance area by the endless belt 107, there are multiple sets of wiper means 108a, 108b,
109a, 109b, . . . , for example, the wiper means 108a, 108b are arranged to be rotatable by a predetermined angle via fulcrums 108c, 108d, respectively, in response to commands from the controller.

On the other hand, these wiper means 108a, 10
On the sides of 8b, 109a, 109b..., there is a chute 1 for receiving items shaken off by each wiper means.
20 are arranged correspondingly, and a container 121 is placed below it.
etc. are set.

In the conveying device 100, when the motor 102 is driven, marine products, etc. in the storage section 101 are transferred to the endless belt 10.
3 and 104, and are conveyed upward in two rows, each weighed at an upper horizontal position, and then transferred onto an endless belt 107. When traveling on the endless belt 107, the articles are shaken off to the side by the action of one of the above-mentioned wiper means, which operates according to the weighing result, and are stored in a lower container 121 etc. through the chute 120. be done. As a result, storage section 101
Items such as seafood stored therein are sorted and sorted into weights within a predetermined range. Note that if the operation of a pair of left and right wiper means, for example wiper means 108a and 108b, is set to shake off items weighed within the same range, and the corresponding chutes are merged, one Items within the same range can be stored within a container.

[0014] By the way, when conveying articles using an endless belt as described above, since the structure is such that the articles are dropped from side to side by wiper means, the number of conveyance paths cannot be increased beyond two, and the processing capacity is limited. There are limits to In addition, in the part where items are picked up from the storage section 101, a transport plate 10
5, there are cases where a plurality of items are locked on 105, and in order to accurately weigh individual items, the items that are locked along with the transport plate 105 must be manually dropped downward. Must be. Therefore, when a large number of these conveying devices 100 are installed, the amount of manpower required is enormous. Moreover, this conveyance device 100
However, rounded items cannot be transported because they tend to roll.

[0015]

[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. It also eliminates the need to provide a complicated reset means before moving to the horizontal transfer path, contributes to miniaturization, prevents damage to product value due to adhesion of lubricating oil, etc., and prevents moisture from entering the product. It does not increase the load on the drive source even if there is a large amount of adhesion, and the simple structure increases the processing capacity for items.Also, it is easy to discharge items that tend to adhere, and the rounded The object of the present invention is to provide a bucket for a bucket conveyor that can transport items that easily roll.

[0016]

[Means for Solving the Problems] The above object is to provide a bucket having a substantially triangular cross section, which is rotatably supported by a spindle on a pair of chains erected in a loop shape on both side walls of the bucket. In a suspended state, the front wall part and the rear wall part are inclined upward, and a plurality of slits are formed in parallel between both outer edges of these two wall parts, and a protrusion is formed in parallel between each of these slits. , a plurality of chains are erected in a loop shape at equal intervals, these chains are also used to support adjacent buckets, all the chains are driven by one driving means, and at least one of the both side walls is A guide piece extending substantially vertically in the suspended state is attached, and the guide piece is brought into contact with each vertical guide member provided along each vertical transfer path portion of the bucket conveyor, and the bucket conveyor An engaging member extending downward is fixed to a stationary part in proximity to each of the horizontal transfer path sections, and the engaging member and the guide piece are engaged with each other while the buckets travel along the horizontal transfer path section. This is achieved by a bucket in a bucket conveyor, characterized in that the bucket rotates around the support shaft to discharge the received items downward.

[0017]

[Operation] The bucket is rotatably supported by a spindle,
In the suspended state, the opening always faces upward, so items can be loaded from any position.Especially in the vertical transfer path, the guide piece is in contact with the vertical guide member, so the bucket posture becomes more stable. The inserted items are accommodated within the space defined by the front wall and the rear wall. 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.

In addition, the buckets are rotatably supported by spindles between multiple rows of chains erected in a loop shape, and one chain is used to support adjacent buckets, so that all the chains are driven by one driving means. Since the structure is not complicated even if the chains are arranged in multiple rows, it is possible to further increase the number of rows by increasing the number of chains, and the processing capacity is increased.

[0019]

Vertical guide members 55, 55, 55, 55 are supported by the device frame, and one end surface 55 of these vertical guide members 55 is
A sheet 56 of a low-friction material such as Teflon is attached to a.

As shown in FIG. 4, the bucket 35 has a substantially triangular cross section and is integrally molded, for example, by injection molding of vinyl chloride resin. Also, this bucket 3
Two holes 36a, 36b and a hole 36c forming a substantially equilateral triangle with these holes are formed in the side wall portions 35a, 35b of 5, respectively, along the opening. The bottom wall of the bucket 35 consists of a front wall part 35c and a rear wall part 35d that is slightly longer than the front wall part 35c. Further, a plurality of parallel slits S are formed between both outer edge portions e of both wall portions 35c and 35d. Furthermore, ribs r are formed between these slits S.

On both side walls 35a and 35b of the bucket 35, which has a substantially triangular cross section, there are a guide piece 37 extending substantially vertically and a chain attachment piece 38 having a substantially L-shape.
and are installed. The guide piece 37 has a curved part 3 at the upper and lower ends.
7a and 37b, and a straight vertical guide plate part 37d between the curved parts 37a and 37b, and a mounting plate part 37e and a shaft locking part formed by bending on the side of the vertical guide plate part 37d. It consists of a plate part 37f. The mounting plate 37e has holes 38a, 38b, and 38c that correspond to the holes 36a, 36b, and 36c formed in the bucket 35, and the shaft locking plate 37f has a shaft locking hole 39. It is formed. On the other hand, the bucket 3 is attached to the L-shaped chain attachment piece 38.
A hole 38a corresponding to the holes 36a and 36b formed in 5,
38b and a shaft locking hole 40 are formed. The guide piece 37 is brought into contact with the side wall 35a of the bucket 35, and the hole 38
a, 38b, and 38c are aligned with the holes 36a, 36b, and 36c, and are attached using rivets 91, 91, and 91. Further, the chain attachment piece 38 is attached to the side wall portion 35 of the bucket 35.
b, and the holes 38a and 38b match the holes 36a and 36b, and are similarly attached using rivets 91 and 91. As shown in FIG. 3, the bucket 35 to which the guide piece 37 and the chain attachment piece 38 are attached includes a pair of shaft locking parts 41 formed at predetermined intervals on the double chain 33;
41, the shaft locking holes 39 and 40 of each guide piece 37 and chain attachment piece 38 are aligned. And the guide piece 37,
A spacer 4 is provided between the two-strand chain 33 as shown in FIG.
9 and 50, and the shaft 51 is inserted between the chain attachment piece 38 and the two-strand chain 33 via the spacers 52 and 50, so that the bucket 35 is
It is positioned and rotatably supported by the chain chains 33, 33. In such a suspended state of the bucket 35,
The front wall portion 35c and the rear wall portion 35d are inclined upward depending on the center of gravity.

In this way, in the conveying device 20 of the embodiment, four consecutive rows are formed between the five two-strand chains 33, 33, 33, 33, 33 wound around the gear devices 23, 24, 25, 26. A bucket conveyor is constructed.

On the other hand, as shown in FIGS. 8 and 9, a mounting member 59 having a U-shaped cross section is located above the pair of two-strand chains 33, 33 in the upper horizontal transfer path portion of the frame 22.
is fixedly installed on the device frame 98 by appropriate means. A rod-shaped engagement member 95 is fixed to the mounting member 59 with screws 75, 75, and the like. As shown in FIG. 1, a chute 96 is disposed below the engaging member 95, and a container or the like is disposed below the chute 96.

The conveying device 20 equipped with a bucket conveyor according to an embodiment of the present invention is constructed as described above.
This effect will be explained below.

[0031] 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. In the vertical transfer path between the gear device 26 and the gear device 23, as shown in FIG. Since it comes into contact with the guide member 55 and is thereby guided to travel in the vertical direction, its posture is maintained constant. However, even if items are thrown into the bucket 35 from this vertical transfer path, the bucket 35 does not swing. Therefore, when an article is thrown into the bucket 35 from the vertical transfer path section of the conveying device 20 in the driven state, the article is stably stored at the bottom of the bucket. The bucket 35 containing the items and moving up the vertical transfer path then travels along the horizontal transfer path. In this way, even when the bucket 35 travels on the horizontal transfer path, the front wall 35c and the rear wall 35d are inclined upward, and the articles will not fall from the bucket 35. When the bucket 35 travels a predetermined distance on the horizontal transfer path and reaches the position where items are accumulated, the guide piece 37 attached to the bucket 35 and extending approximately vertically
It comes into contact with a rod-shaped engagement member 95 that extends downward. When the guide piece 37 comes into contact with the engagement member 95, as shown in FIG. 8, during subsequent travel, the bucket 35 rotates from the solid line position to the broken line position about the shafts 51, 51 as support axes. As a result, the item falls downward and is stored in a container or the like.

After dropping the item, the front wall 35c and rear wall 35d of the bucket 35 return to the upward slope due to their own weight, and from the remaining horizontal transfer path to the downward vertical transfer path and the lower After traveling along the horizontal transfer path section, the posture is reliably maintained by the guide piece 37 and transferred along the vertical transfer path section between the gear device 26 and the gear device 23. The following buckets also drop the articles one by one using the engaging member 95, return to their postures in the same way, and travel. Accordingly, items are sequentially placed in buckets and accumulated in containers.

A conveyance device equipped with a bucket conveyor according to an embodiment of the present invention performs the above-mentioned functions, and has the following effects.

That is, in the above embodiment, the articles are introduced into the vertical transfer path of the bucket conveyor, but they can also be introduced into the horizontal transfer path above, and the introduction position can be set as appropriate. . Furthermore, the processing capacity can be freely set by adjusting the rotational force of the motor 27, the number of bucket conveyors arranged, etc.

Further, the above-mentioned conveying device 20 can be effectively applied, for example, as a conveying device for marine products, but it can of course also be applied to other products, such as agricultural products such as chestnuts, which are rounded and easy to roll.

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

Furthermore, since the bucket 35 is formed with a plurality of slits S, the 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 can be smoothly discharged downward by reducing frictional force.

Further, in the above embodiment, the bucket conveyor is arranged in four rows as shown in FIG. 1, but it may be arranged in a single row or in more than one row.

Although the conveyance device equipped with a bucket according to one 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. is possible.

For example, in the above embodiment, the bucket 35
is rotatably supported by two shafts 51, 51 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 embodiment, the guide piece 37 extending substantially vertically and the L-shaped chain attachment piece 38 were attached to the bucket 35, but both guide pieces 37, 37 extending substantially vertically were attached to the bucket 35. It's good as well. In that case, it is necessary to provide two vertical guide members 55 for each bucket in the vertical transfer path, but it is possible to hold the bucket 35 more stably when loading items. Further, when both guide pieces 37 are used, there is no need to newly form holes in the bucket 35, and the bucket 35 can be attached by using the holes 36a, 36b, and 36c.

Further, in the above embodiment, the engaging member 95 was formed into a rod shape and fixed to a stationary part such as the device frame, but the engaging member 66 as shown in FIG.
It can also be fixed to the actuator 65 of No. 4. That is, the engaging member 66 has a connecting portion 72 that includes a rotation shaft 67,
The short side arm portion 73 and the long side arm portion 68 form a substantially L-shape. To install such an engaging member 66, a solenoid mounting member 97 having a U-shaped cross section is provided, similar to the mounting member 59 shown in FIG. The solenoid mounting member 97 is fixed to a stationary part such as an apparatus frame. The rotation shaft 67 of the engagement member 66 is rotatably supported by a fixed plate (not shown) that is disposed to hang down from the solenoid mounting member 97 . The long side arm portion 68 of the engagement member 66 has a substantially L-shaped hook portion 70 with a cutout portion 69 and a rod portion 71 extending downward from the hook portion 70 .
is formed. Further, the connecting portion 72 has a built-in torsion coil spring.

In the engagement member 66 formed in this manner, the short side arm portion 73 is inserted from below the solenoid mounting member 97 into the large hole 60 formed at the bottom of the solenoid mounting member 97, and the long side The hook portion 70 of the arm portion 68 is inserted into the small hole 61 and installed on the solenoid mounting member 97. The engaging member 66 is connected to the rotation shaft 6 in FIG.
Even if an external force to rotate counterclockwise around 7 is applied, when that force is released, the spring force of the torsion coil spring causes the torsion coil spring to move back clockwise, returning to the installed state of the torsion coil spring. Note that when the engagement member 66 rotates, the one end 70a of the hook portion 70 and the one end 71a of the rod portion 71 come into contact with the bottom plate 97c of the solenoid mounting member 97, thereby reducing the rotation range of the engagement member 66. is regulated.

[0044] Such an electromagnetic solenoid 64 is connected to a controller (not shown), and is excited in response to a command from the controller. In the electromagnetic solenoid 64, in a normal non-energized state, the actuator 65 is at the position indicated by the broken line in FIG.
One end 71a of 1 is the bottom plate 97 of the solenoid mounting member 97.
It is in contact with c. That is, in the upper position. When the electromagnetic solenoid 64 is energized from such a de-energized state,
The actuator 65 is in the solid line position, and at the same time, the engaging member 66 is rotated and is 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 97c of the solenoid mounting member 97, 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 the collision from occurring. The generation of abnormal noise is prevented. Similarly, when the engagement member 66 is in the upper position, the rod portion 71
By attaching a buffer material 74 to the portion that contacts the one end 71a, it is possible to prevent abnormal noise from occurring due to a collision at the time when excitation is completed.

In this way, the engaging member 66 is coupled to the actuator 65 of the electromagnetic solenoid 64, and the engaging member 66 is moved to the engaged position and the disengaged position with respect to the bucket 35 by energizing and de-energizing the solenoid 64. Alternatively, only the desired items in the bucket 35 may be dropped.

Further, instead of the electromagnetic solenoid 64, the engaging member may be coupled to a drive rod of a pneumatic or hydraulic cylinder. In this case, the same effect as in the embodiment can be achieved by connecting a solenoid valve to this cylinder and opening and closing this valve.

[0047]

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 transfer path section or the vertical transfer path section. The guide piece allows items to be stably received even on road sections. Therefore, the work space in which the bucket conveyor is used can be diversified. Furthermore, no reset means is required to change the posture of the bucket to receive the articles, and the overall structure can be simplified. In addition, since no lubricating oil is particularly required during transportation, there is no problem of lubricating oil adhering to the product and damaging the commercial value, making it effective for transporting foods and the like. Furthermore, since the water adhering to the items can be allowed to fall downward through the slits, the weight of the entire bucket can be reduced, the driving load can be reduced, and washing is also facilitated. Furthermore, since the protrusion is provided, it is possible to prevent some items from getting caught in the slit S, and to reduce frictional force so that they can be smoothly discharged downward. Furthermore, the processing capacity can be further increased by appropriately increasing the number of loop-shaped chains, and in this case, there is no need to increase the number of drive means, so the overall structure can be simplified. In addition, it is also possible to transport items that are rounded and easily roll.
