[Detailed description of the invention]

0001

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 formed 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 way, the bucket 16 has two shafts 18
, 19 and are successively set on the frame 3 at predetermined intervals. When items are transported by a series of buckets 16 set on the pedestal 3, the items are sequentially thrown into the horizontal buckets 16 from above the pedestal 3.

By the way, when taking out articles from such a bucket 16, the ends 14a and 15a of the plates 14 and 15 are arranged at the place where the articles are accumulated, and thereby the short length of the bucket 16 passing therethrough is shortened. Remove the shaft 19 from the plates 14, 15 and move the bucket 16 to the other long shaft 18.
The container is rotated using the fulcrum as a fulcrum, and the stored items are allowed to fall downward. The bucket 16, which has become empty after dropping the items downward, is then transferred to a vertical transfer path section from the gear device 5 to the gear device 6, a lower horizontal transfer path section from the gear device 6 to the gear device 7, and a lower horizontal transfer path section from the gear device 7 to the gear device 7. It runs suspended by a long shaft 18 on an upward vertical transfer path leading to the gear device 8 . Near the end of the upward movement in this vertical transfer path section, the short axis 19 is reset onto the plates 14 and 15 by appropriate means.

[0009] As described above, in the conventional bucket conveyor, when an article is dropped from the bucket 16, the opening is oriented in the horizontal direction, and therefore a reset means is required to allow the article to be accommodated again.

[0010] Furthermore, conventionally, the item cannot be loaded again until after its posture has been corrected by the reset means. Therefore, the loading position is limited to the upper horizontal transfer path, and there are restrictions on the work space etc. where the bucket conveyor is used.

[0011] Furthermore, in the portion running on the horizontal transfer path, the short shaft 19 slides on the plates 14 and 15, so a means of lubricating this sliding portion is required, making the device complicated. It had become a thing. Further, if the hydraulic oil used in this lubricating means adheres to the inside of the bucket, the commercial value of the transported items may be impaired, so sufficient consideration has been required when transporting foodstuffs and the like. Furthermore, if a large amount of moisture adheres to the item, the entire bucket becomes heavy, increasing the load on the drive source. Furthermore, if the item has a property that it tends to stick to the surroundings, there is a problem that the item will get caught in the bucket and not be ejected.

0012

[Problems to be Solved by the Invention] The present invention has been made in view of the above-mentioned problems, and even in a vertically arranged bucket conveyor, articles can be inputted not only from the horizontal transfer path but also from the vertical transfer path. In addition, even if the transported goods are foods, there is no risk of reducing the product value due to adhesion of lubricating oil, etc., and the structure does not require a reset means to discharge the goods. The object of the present invention is to provide a bucket for a bucket conveyor that does not increase the load on a drive source even if a large amount of particles are attached to the bucket, and allows for easy discharge of articles.

[0013]

[Means for solving the problem] The above object is to provide a bucket which has a substantially triangular cross section, is rotatably supported by a pair of chains on both side walls of the bucket, and is suspended from the front wall. and the rear wall are inclined upward, a plurality of slits are formed in parallel between both outer edges of these wall parts, and a protrusion is formed in parallel between each of these slits, and
A guide piece extending substantially vertically in the suspended state is attached to at least one of the both side walls, and the guide piece is brought into contact with a vertical guide member provided along the vertical transfer path of the bucket conveyor. , and an engaging member extending downward is fixed to a stationary portion adjacent to the horizontal transfer path portion, and the engaging member and the guide piece are engaged with each other while the bucket travels on the horizontal transfer path portion. 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.

[0014]

[Operation] The bucket is rotatably supported by a spindle,
Since the opening always faces upward in the suspended state, the bucket can be loaded from any position.Especially in the vertical transfer path, the guide piece comes into contact with the vertical guide member, so the attitude of the bucket can be adjusted. Stabilize. Further, in order to discharge the article, the guide piece engages with the engaging member in the horizontal transfer path, so that the bucket rotates around the support shaft, and the article is discharged. When the items are discharged, the bucket's own weight causes the opening to face upward. 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. Moreover, when the bucket is tilted to discharge the articles, the protrusions allow the articles to be discharged smoothly.

[0015]

are arranged along the traveling direction to prevent the two-strand chain 33 from loosening.

As shown in FIG. 4, the bucket 35 has a substantially triangular cross section and is integrally molded, for example, by vacuum molding from 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.

A guide piece 37 extending substantially vertically and a chain attachment piece 38 having a substantially L-shape are attached to both side wall portions 35a and 35b of the bucket 35, which has a substantially triangular cross section in this manner. The guide piece 37 has a curved part 37 at the upper and lower ends.
a, 37b, and a straight vertical guide plate part 37d between the curved parts 37a and 37b, and a mounting plate part 37e and 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 35 is attached to the L-shaped chain attachment piece 38.
Holes 38a, 3 corresponding to holes 36a, 36b formed in
8b and a shaft locking hole 40 are formed. Guide piece 3
7 is brought into contact with the side wall portion 35a of the bucket 35, and the hole 38a is
, 38b, 38c are aligned with the holes 36a, 36b, 36c, and attached using rivets 91, 91, 91, etc. 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, 91, etc. As shown in FIG. 3, the bucket 35 to which the guide piece 37 and the chain attachment piece 38 are attached is connected to a pair of shaft locking parts 41 formed at predetermined intervals on the two-strand chain 33.
, 41 are aligned with the shaft locking holes 39 and 40 of the guide piece 37 and the chain attachment piece 38. 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 54 is inserted between the chain attachment piece 38 and the two-strand chain 33 via the spacers 52 and 53.
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 manner, 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.

[0026] In this way, when the bucket conveyor is of a multiple type, the adjacent buckets 35, 3
One two-strand chain 33 is arranged between the buckets 5 and 5, and the two-strand chain 33 also serves to support the adjacent buckets 35, 35. Therefore, in the embodiment, four rows of buckets are supported by five two-strand chains.

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.

[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. 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 and 54 as support axes. As a result, the item falls downward and is stored in a container or the like.

After the items have been dropped, 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 conveying device equipped with a bucket conveyor according to an embodiment of the present invention operates as described above, 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 as a conveying device for marine products, for example, but it can of course also be applied to other products, such as agricultural products such as chestnuts.

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, 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 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 a device frame 98. 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 . Long side arm portion 6 of engagement member 66
A substantially L-shaped hook portion 70 having a cutout portion 69 and a rod portion 71 extending downward from the hook portion 70 are formed at the distal end portion of the hook portion 8 . 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 formed at the bottom of the solenoid mounting member 97 from below 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.

[0042] 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 manner, the engaging member 66 is coupled to the actuator 65 of the electromagnetic solenoid 64, and the engaging member 66 is moved between 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.

Furthermore, 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.

[0045]

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, but especially in the vertical transfer path section. In the section, items can be loaded in a stable position. 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. Also, since no lubricating oil is required during transportation,
It is effective for transporting foods, etc., without the problem of lubricating oil adhering to the product and damaging the product value. 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. Further, 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.
