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

0002

[Prior Art and Problems Therewith] Generally, agricultural products, marine products, etc. are roughly sorted at each market, and depending on the product, they are then sent to a processing factory. In markets and processing factories, these items may be sorted into certain categories based on size, weight, etc. In that case, for example, it is preferable that small marine products such as scallops or cod roe be weighed one by one and automatically sorted into a certain frame while being transported.

[0003] By the way, when this type of item is conveyed by a vertically arranged bucket conveyor, the bucket is conventionally provided with two support parts on both sides of the opening for loading and unloading the item. A mounting shaft was inserted through the support part, and the two mounting shafts were attached between the chains.

FIG. 11 shows an example of a conventional transport device using a bucket conveyor that circulates horizontal and vertical transport using a pair of chains.

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. 12, the conveyance 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
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. The plates 14 and 15 are placed at the place where the items are accumulated.
By arranging the ends 14a and 15a of the bucket 16, the short axis 19 of the bucket 16 passing through these parts is removed from the plates 14 and 15, and the bucket 16 is rotated about the other long axis 18 as a fulcrum, and the item is dropped downward. I'm letting you do it.

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 pedestal 3 while being suspended by one long shaft, further moves upward in the vertical direction, and is placed on the plates 14 and 15 by appropriate means near the end of the upward movement. Short axis 1
9 is reset.

Therefore, in the conventional bucket conveyor, the bucket 16 moves vertically in a suspended position with the opening facing in the lateral direction, and articles cannot be thrown into the part that moves in this position. Therefore, there is a limit to the work space etc. in which the bucket conveyor can be used.

[0012] Furthermore, in order to be able to charge the items into the bucket 16 from the vertical transfer path, for example, the bucket is supported by a single axis at an intermediate position in the width direction, and the bucket is not rotated inadvertently. 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 large. As the bucket becomes larger, there is a problem in that the function for discharging items from the bucket also becomes larger.

[0013]Furthermore, with this conveyance device 1, it is not possible to sort articles by weight during conveyance. If this device is to be used to sort items by weight, multiple rows of bucket conveyors must be set on the pedestal 3, and pre-weighed items must be sorted and then fed into these bucket conveyors. Therefore, automation is very difficult with this device. There is also the problem that the device becomes large due to weighing and transportation.

[0014] Furthermore, in the above conveying device, since the short shaft 19 slides on the plates 14 and 15, means for lubricating this sliding part is required, and the hydraulic oil used for this lubricating means is inside the bucket. There is a problem that if it adheres to the surface, the commercial value of the transported item will be damaged. 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 its surroundings, it will get caught in the bucket and there is a problem that the item will not be ejected.

[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. In addition, there is no need to provide a complicated reset means before moving to the horizontal transfer path, contributing to miniaturization, and there is no loss of product value due to adhesion of lubricating oil, etc., and there is no need to install moisture on the product. The object of the present invention is to provide a bucket and discharge mechanism for a bucket conveyor that does not increase the load on the drive source even if a large amount of articles are attached, and that allows for easy discharge of articles, is compact, and achieves complete automation. .

[0016]

[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 a plurality of electromagnetic solenoids are provided in a stationary part at predetermined position intervals along the horizontal transfer path portion of the bucket conveyor, and an engaging member extending downward is attached to the actuator of each electromagnetic solenoid. The engaging member selectively takes an engaged position and a non-engaged position by the reciprocating movement of the actuator by energizing and de-energizing the solenoid. The items are weighed by a weighing machine, and the corresponding electromagnetic solenoid is energized depending on the size range of the weighing result of the weighing machine, and the electromagnetic solenoid corresponding to the size range is energized. The bucket receives the weighed item by causing the member to assume the engagement position, and the guide piece is engaged with the engagement member of the corresponding electromagnetic solenoid while being transferred along the horizontal transfer path. a bucket and a discharge mechanism in a bucket conveyor, characterized in that the bucket is rotated around the support shaft so that the stored items within the range fall downward and are discharged; achieved by.

[0017] Also, the above object is that the bucket 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 rear wall is upwardly inclined, a plurality of slits are formed in parallel between both outer edges of both of these wall parts, and protrusions are formed in parallel between each of these slits, and at least one of the both side wall parts is A guide piece extending substantially vertically in the suspended state is attached, and the guide piece is brought into contact with a vertical guide member provided along a vertical transfer path portion of the bucket conveyor, and the horizontal transfer of the bucket conveyor A plurality of electromagnetic solenoids are provided in a stationary section at predetermined intervals along the road section, and an engaging member extending downward is attached to the actuator of each electromagnetic solenoid, so that the electromagnetic solenoids are energized and de-energized. By reciprocating the actuator, the engaging member selectively takes an engaged position and a non-engaged position, and one article fed to the bucket in the vertical transfer path is weighed by a weighing machine. The weighing results of the weighing machine are <a, <b, <c, <d, <e... (a<b
<c<d<e<...), the electromagnets are sequentially arranged toward the downstream side corresponding to a, b, c... The solenoid is energized and the engagement member assumes the engagement position so that the bucket receives the weighed item and moves the guide piece to the corresponding position while being transferred along the horizontal transfer path. The bucket is engaged with the engaging member of the electromagnetic solenoid, and the bucket is rotated around the spindle to sequentially transport the stored items downward while sequentially transferring them to the downstream side according to the weighing results in the ranking. This is achieved by a bucket and a discharge mechanism in a bucket conveyor, which is characterized by being configured to discharge.

[0018]

[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. In addition, to discharge the item, an electromagnetic solenoid that is energized in accordance with the weight of the item is activated, so that the bucket engages the engagement member at a predetermined location according to the weight of the item, and the item falls downward. . When the item is discharged,
The opening of the bucket faces upward due to its own weight. 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. Further, by arranging electromagnetic solenoids that are excited in accordance with the weight results of the items on the downstream side in order according to the size of the weight results, the items can be sorted downward according to the order of the weight results.

, 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.
The shaft 51 is inserted through the shafts 9 and 50, and spacers 52 and 53 are provided between the chain attachment piece 38 and the two-strand chain 33.
A shaft 54 is inserted through the bucket 35, whereby the bucket 35 is positioned and rotatably supported by the two-strand 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 due to the position of 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.

[0029] 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 33, 33. 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 pair of two-strand chains 33 and 33 are placed in the upper horizontal transfer path portion of the frame 22, each having a U-shaped cross section in the chain conveying direction. and mounting flanges 59a, 59.
A solenoid mounting member 59 having an opening marked b is fixedly installed on a stationary part such as an apparatus frame. A plurality of pairs of large holes 60 and small holes 61 are formed in the bottom plate 59c of the solenoid mounting member 59 at predetermined intervals. The solenoid mounting plate 59 has mounting flanges 59a and 59b.
They are integrally assembled by bolting between the and the device frame, and the position is adjusted using the elongated holes 62.

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 manner, 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 large hole 60 from below the solenoid mounting member 59. 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 clockwise and return to the installed state of the torsion coil spring. 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.

[0033] In this way, each electromagnetic solenoid 64 to which the engaging member 66 is attached below is connected to a controller (not shown), and is energized in accordance with a command from the controller. The electromagnetic solenoid 64 operates when the actuator 6 is in a normal de-energized state.
5 is located at the broken line position in FIG.
a is in contact with the bottom plate 59c of the solenoid mounting member 59. That is, in the upper position. 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 that time, one end 70a of the hook portion 70 comes into contact with the bottom plate 59c of the mounting member 59, but the hook portion 70
By attaching a cushioning material 58 such as urethane rubber to the portion that abuts the one end 70a, the generation of abnormal noise due to a collision can be 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.

Conveying device 20 equipped with buckets and a discharge mechanism in a bucket conveyor according to an embodiment of the present invention
Although 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. The operation of the conveying device 20 that sorts marine products of the same type by weight will be described below.

The motor 27 is now driven and the gear system 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. After weighing, the scallops and the like are transferred to a bucket 35 that is conveyed through a vertical transfer path section between the gear device 26 and the gear device 23 in the conveyance device 20.
One piece is supplied within the same period. In this vertical transfer path section, the bucket 35 is moved by the curved portion 37 of the guide piece 37 as shown in FIG.
a and 37b come into contact with the vertical guide member 55, which guides the vertical movement, so that the posture is maintained constant. That is, even if items such as scallops are thrown into the bucket 35 from the vertical transfer path, the bucket 35 will not swing. In addition, in the example, bucket 3
The scallops etc. put into the container 5 are divided into eight groups, and the group to which the scallops etc. belong is input into the controller by 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.

Thereafter, in the following bucket, a predetermined electromagnetic solenoid is energized, 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.

When the bucket 35 finishes transporting the contents, the front wall part 35c and the rear wall part 35d return to the upward inclination due to their own weight, and the remaining horizontal transport path section downwards to the vertical transport path section and the rear wall section 35d. , travels on the lower horizontal transfer path section, and again,
The posture is maintained by the guide piece 37, and the device is transferred along the vertical transfer path between the gear device 26 and the gear device 23.

The conveying device equipped with the bucket and discharge mechanism in 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., sanitary and
Periodic cleaning is performed, and since the electrical 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 product, that is, the scallop scallops, was introduced into the vertical transfer path section of the bucket conveyor, but it is also possible to input the product into the horizontal transfer path section above, and the input position can be changed. It can be set as appropriate.

Further, 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, 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 the frictional force can be reduced so that they can be smoothly discharged downward.

[0045] Above, a conveyance device equipped with a bucket according to an embodiment of the present invention has been described, but of course the present invention is not limited to the above embodiment, and various modifications can be made based on the technical idea of the present invention. It 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 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.

Further, in the above embodiment, the bucket conveyor is configured in four rows, but it may be a single row or more, and the number of electromagnetic solenoids, chutes, etc. can be changed as appropriate. .

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 the bucket 35 can be held 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.

Furthermore, in the above embodiment, the corresponding electromagnetic solenoid 64 is set according to the size range in which the results of the weighing machine fall, without particularly determining the order of magnitude of the weighing results. I tried to excite it, but instead of this,
From the upstream side, the weighting results increase from small to large, that is, the weighting results are <a, <b, <c, <d... (
a<b<c<d...) Similarly, heavier items may be sorted toward the downstream side and discharged to the outside through corresponding chutes.

In this case, clearly from the chute on the downstream side toward the upstream side, the weight of the items is less than a, and from a to b.
range, range from b to c, range from c to d, etc.
・Similarly, when a large number of electromagnetic solenoids are arranged as in the example, items within a predetermined weight, such as scallops, are discharged to the outside in a detailed manner, and the price is determined by carefully packing the items into boxes. be able to.

Further, in the above embodiment, a large number of electromagnetic solenoids are arranged along the horizontal transfer path of the bucket, but only two are provided, and if an item with a weight smaller than a is stored in the bucket. When the items are transported, the solenoid on the upstream side is energized to discharge the items whose weight is less than a to the outside from the corresponding chute, and then the bucket containing the items whose weight is less than b (b>a) is When the item reaches a downstream solenoid, the downstream solenoid may be energized to discharge the item and discharge it to the outside from the corresponding chute. Furthermore, if an engaging member is simply fixed instead of an electromagnetic solenoid on the downstream side, all the buckets are emptied and guided to the right vertical transfer path in FIG. In this way, from the downstream chute, the weight M within a predetermined range (a<M<b)
can be supplied, for example, for boxing scallops.

[0053]

[Effects of the Invention] As explained above, according to the bucket and discharge mechanism of the bucket conveyor according to the present invention,
Even if the bucket is a vertical transfer path, articles can be thrown in, and therefore the work space in which the bucket conveyor is used can be diversified. In addition, in the suspended state, the bucket is rotatable and the front and rear walls are slanted upwards, so after discharging the items, the opening naturally faces upwards, so the bucket is in a position to receive the items. No reset means is required for making changes, and the overall structure can be simplified. In addition, since the guide piece extending substantially vertically is guided and transferred by the vertical transfer path, it is possible to prevent the bucket from inadvertently rotating when loading the items without making the bucket particularly long in the vertical direction. Further, since there are no sliding parts when the bucket is transported, there is no risk that the hydraulic oil of the lubricating means will adhere to the items, and the items can be transported in good condition at all times. 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, reducing the driving load and making washing easier. 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.

[0054] Furthermore, the weighed items stored in the bucket are placed in a predetermined order by activating an electromagnetic solenoid that is energized or de-energized according to the weight range. Because it can be discharged to a place,
It is possible to automatically sort within a certain range while transporting, achieving automation, and the entire device is compact.
