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.

[0017] 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.

In FIG. 8, an electromagnetic solenoid device 64 that operates in response to a weighing signal from a weighing mechanism (not shown) is fixed to a mounting plate 97, and a solenoid built into this main body receives the detection signal. Normally, the actuator 65 is in the position shown by the dotted line, and in FIG. 8, the state in which the solenoid is excited and activated is shown by the solid line. The main arm 68 is inserted through a hole 60 formed at 97, which forms a part of the device 64, and an engaging part 71 is formed in the other part of the main arm part 68, which extends upward. The arm part is inserted through a hole 61 formed in the mounting plate 97 of the same 70, and the tip thereof is bent horizontally to attach the electromagnetic solenoid device 64.
In the operating state, this bent portion 70a is in contact with the urethane rubber 58. Also, urethane rubber 74 is attached to the lower surface of the mounting plate 97 opposite to this urethane rubber 58. Further, a return spring (not shown) is provided on the shaft 67 that engages the main arm portion 68 and the operating arm 73. Therefore, when the electromagnetic solenoid device 64 is de-energized, the actuator 65 assumes the position shown by the dotted line due to this spring force, and the main arm portion 68 rotates counterclockwise around the shaft 67 from the position shown by the solid line to the engaging portion. One end 71a of 71 comes into contact with urethane rubber 64, thereby regulating its position. The urethane rubber 58, 74 causes the main arm portion 68 to reciprocate around the shaft 67 depending on whether the solenoid 64 is activated or deactivated.
This is to prevent impact noise from being emitted when the parts a collide. It also protects these parts.

Further downstream in the upper horizontal transfer path portion of the frame 22, a mounting member 59 having a U-shaped cross section is located above the pair of two-strand chains 33, 33, as shown in FIGS. 9 and 10. 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.

[0021] Now, the motor 27 is 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. 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, the items weighed by the weighing machine (not shown) are transferred from the vertical transfer path of the conveying device 20 in the driving state to the bucket 35.
When placed inside the bucket, the items are stored in a stable state 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.

[0022] Although it is transferred as described above,
When reaching the position of the electromagnetic solenoid device 64 shown in FIG. 1, this bucket 35 is now being transferred by a chain at a predetermined pitch and timing, and the items weighed in the vertical transfer path are over a predetermined value. If it is heavy, the solenoid is energized and the actuator 65 assumes the position shown by the solid line as shown in FIG. As a result, the main arm portion rotates clockwise around the shaft 67, and the engaging portion 71 comes into contact with the guide piece 37, and the bucket 35 passes through the state shown by the chain line and solid line, and the bucket 35 rotates around the shaft 51, 54. It pivots around so that the items it contains (e.g. scallops) are discharged downwardly and fed to the outside along chute 100. Furthermore, the buckets 35 are conveyed at a predetermined pitch and at a predetermined timing, but if the weight of the items accommodated in the vertical transfer path is less than a predetermined value, the solenoid 64 will not be energized, and therefore the actuator 65 will move as shown by the dotted line. Therefore, the engaging portion 71 is located at an upper position than shown in the figure and does not engage with the guide piece 37, so that the bucket 35 is transferred to the downstream side while maintaining its suspended state.

When the bucket 35 travels a predetermined distance along the horizontal transfer path and reaches the position where items are collected, the guide piece 37 attached to the bucket 35 and extending approximately vertically engages with a rod-shaped engagement member extending downward. It comes into contact with member 95. Guide piece 3
7 comes into contact with the engaging member 95, as shown in FIG.
During subsequent travel, the bucket 35 rotates from the solid line position to the broken line position using 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, 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.

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 front wall 35c and the rear wall 35d of the bucket 35 are formed into a flat plate shape, but as in the bucket 77 shown in FIG. A plurality of slits 80 may be formed over 77d. By providing the slit 80 in this way,
Moisture or the like adhering to the stored items can be removed from the bottom during transport, and items that tend to adhere to the inner walls of the bucket 35, such as certain types of seafood, can easily fall downward. Also, instead of slits, they may simply be holes. Furthermore, since the buckets are lighter, the load on the motors that drive them can be reduced.

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 articles. 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, while the bucket is traveling along the vertical transfer path, an item is weighed by a weighing machine (not shown), and if the weight of the item exceeds a predetermined value, the solenoid of the electromagnetic solenoid is is excited, and an electromagnetic solenoid in the horizontal transfer path of the bucket receives a signal indicating the weighing result of the weighing machine, engages the bucket, and discharges the item into the chute 100.
6, all items weighing less than a predetermined weight are ejected, but instead, if the weight result is less than a predetermined weight, the electromagnetic solenoid 64 is energized to eject the items from the bucket into the chute 100. The downstream engaging portion 95 may discharge all items weighing more than a predetermined value into the chute 96.

Furthermore, it is detected that the weighing result of the weighing machine is within a predetermined range, and this detection signal is supplied to an electromagnetic solenoid device so that the items in the bucket that have arrived at this position are discharged into the chute 100. However, all other weights, that is, items weighing less than the first predetermined value and more than the second predetermined value, may be discharged into the chute 96.

[0035]

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 a vertical transfer path, and therefore the work space where the bucket conveyor is used is improved. Diversification can be achieved. 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, it is possible to reliably sort items that are below or above a predetermined value, regardless of the shape of the items.
