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 vertically arranged.

[0002]

2. Description of the Related Art FIG. 11 shows a conventional bucket conveyor with a bucket mounted between a pair of chains and circulating horizontal and vertical conveyance by these chains.

[0003] In this transfer apparatus 1, gear units 4, 5, 6, and 7 are supported in a rectangular gantry 3 constituted by angles 2. The rotational force of a motor (not shown) is transmitted to a pulley 8 provided on the gear device 4 via a belt, and a driving force is transmitted to the conveying means 9 via the gear device 4.

As shown in FIG. 12, the conveying means 9 is composed of a pair of two-chain chains 10 and 11.
A pair of shaft locking portions 12, 12, 13 and 13 are formed at predetermined intervals in the thread chains 10 and 11. On the inner side of these two-chain chains 10, 11, plates 14, 15 are respectively arranged adjacent to the chains.

[0005] On the other hand, the bucket 16 has an opening on one side and a substantially trapezoidal cross section, and both ends of both side walls 16a and 16b arranged in parallel with the two-strand chains 10 and 11 are provided with shaft mounting members. Bosses 17a, 17b, 17c, and 17d are formed.

The bucket 16 having such a boss is formed.
, The long axis 18 is inserted into the bosses 17b and 17d on the front side in the transport direction A indicated by the arrows in FIGS.
Both ends of the long shaft 18 are inserted into the two-chain chains 10 and 11 and are locked by the shaft locking portions 12 and 13, respectively. On the other hand, the bosses 17a, 17
A short shaft 19 is inserted through c, and both ends of the short shaft 19 are locked to the plates 14 and 15.

As described above, the bucket 16 has two shafts 1
8 and 19 are inserted and set on the gantry 3 continuously at predetermined intervals. A series of buckets 16 set on the gantry 3
Therefore, when the articles are conveyed, the articles are sequentially put into the horizontal bucket 16 from a position above the gantry 3.

In order to take out articles from such a bucket 16, the ends 14a, 15a of the plates 14, 15 are arranged at a place where the articles are to be collected, thereby shortening the length of the bucket 16 passing therethrough. The shaft 19 is removed from the plates 14 and 15, and the bucket 16 is connected to the other long shaft 18
Is pivoted on the fulcrum to drop the contents downward. The bucket 16 that has been emptied by dropping the goods downward is then moved from the vertical transfer path section from the gear unit 5 to the gear unit 6, the lower horizontal transfer path unit from the gear unit 6 to the gear unit 7, and from the gear unit 7. The vehicle travels on a vertical transfer path section extending to the gear device 8 while being suspended by the long shaft 18. In the vicinity of the end of the upward movement in the vertical transfer path, the short axis 19 is reset on the plates 14 and 15 by appropriate means.

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, so that resetting means for re-accommodating the article is required.

[0010] Conventionally, it is impossible to re-enter an article only after the posture is corrected by the reset means. Therefore, the loading position is limited to the upper horizontal transfer path, and there is a limit to the work space using the bucket conveyor.

Further, in a portion traveling on the horizontal transfer path, the short shaft 19 slides on the plates 14 and 15 to move. Therefore, a lubricating means for the sliding portion is required, and the apparatus is complicated. Had become something. Further, if the hydraulic oil used in the lubricating means adheres to the inside of the bucket, the commercial value of the conveyed product may be impaired. If a large amount of water adheres to the product, the entire bucket becomes heavy, increasing the load on the drive source. In addition, there is a problem that if the article has such a property as to easily adhere to the surroundings, the article is caught on the bucket and the article is not discharged.

[0012]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and is intended to supply articles not only from a horizontal transfer path but also from a vertical transfer path, even in a vertically arranged bucket conveyor. Even if the conveyed product is food, there is no danger of deteriorating the commercial value due to the adhesion of lubricating oil and the like, and the product can be discharged with a structure that does not require resetting means. It is an object of the present invention to provide a bucket in a bucket conveyor which does not increase the load on a driving source even if a large amount of ash adheres thereto and allows easy discharge of articles.

[0013]

SUMMARY OF THE INVENTION The object of the present invention is to provide a bucket having a substantially triangular cross section, which is rotatably supported on a pair of chains at both side walls by a support shaft. The portion and the rear wall portion are inclined upward, to form a plurality of slits arranged in parallel between both outer edges of these wall portions, and to form a ridge in parallel between these slits, and
A guide piece that extends substantially vertically in the suspended state is attached to at least one of the side walls, and the guide piece is brought into contact with a vertical guide member provided along a vertical transfer path of the bucket conveyor. And an engaging member extending downward is fixed to a stationary portion in proximity to the horizontal transfer path, and the engaging member and the guide piece are engaged while the bucket runs on the horizontal transfer path. In turn, the bucket is achieved by a bucket on a bucket conveyor characterized in that it rotates about the spindle and discharges the received goods downward.

[0014]

[Action] The bucket rotatably supported by the support shaft is
Since the opening is always facing upward in the suspended state, it can be inserted from any position. In particular, in the vertical transfer path section, the guide piece abuts on the vertical guide member, so the bucket posture is more Stabilize. When the guide piece engages with the engaging member in the horizontal transfer path, the bucket rotates about the support shaft and the article is ejected. When the article is discharged, the opening of the bucket is directed upward by its own weight. Furthermore, since the moisture adhering to the article can be dropped downward from the slit, the total weight of the bucket for transporting the article can be reduced, and the load on the drive source can be reduced. Further, when the bucket is tilted to discharge the articles, the articles are smoothly discharged by the ridges.

One double chain 33 is arranged between the five, and the double chain 33 also supports the adjacent buckets 35, 35. Therefore, in the embodiment, four rows of buckets are supported by five two-row chains.

On the other hand, in the upper horizontal transfer path portion of the gantry 22, an attachment member 59 having a U-shaped cross section is located above the pair of two-chain chains 33, 33 as shown in FIGS.
Are fixedly installed on the device frame 98 by appropriate means. A rod-shaped engaging member 95 is fixed to the mounting member 59 by 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 transport device 20 having the bucket conveyor according to one embodiment of the present invention is configured as described above.
Hereinafter, this operation will be described.

Now, the motor 27 is driven and the gear train 23
To five rows of two-row chains 33, 33, 33, 33, 33
Power is transmitted to the other gear devices 24, 25, 26 via the. Therefore, supported by the two double-row chains 33, 33, four rows of bucket conveyors
1 and 2 in the direction of arrow B in FIG. In the vertical transfer path between the gear device 26 and the gear device 23, as shown in FIG. 6, the bucket 35 has upper and lower curved portions 37a, 37b (only one of which is shown) of a vertically extending guide piece 37. Since the guide member 55 comes into contact with the guide member 55 to guide the traveling in the vertical direction, the posture is kept constant. However, the goods are transferred from the vertical transfer path to the bucket 35.
The bucket 35 does not swing even if it is thrown in. Therefore, when an article is put into the bucket 35 from the vertical transfer path portion of the transport device 20 in the driven state, the article is stored in a stable state at the bottom of the bucket. The bucket 35 that accommodates articles and moves upward in the vertical transfer path then travels in 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, so that articles do not fall from the bucket 35. When the bucket 35 travels a predetermined distance on the horizontal transfer path and reaches a position where goods are accumulated,
The substantially vertically extending guide piece 37 attached to the bucket 35 abuts on a rod-shaped engaging member 95 extending downward. When the guide piece 37 comes into contact with the engagement member 95, FIG.
As shown in FIG.
Rotates in the direction from the solid line position to the broken line position with the shafts 51 and 54 as support shafts. This causes the item to fall down,
It is stored in a container or the like.

The bucket 35 after dropping the articles returns to the front wall portion 35c and the rear wall portion 35d by the weight of itself again, and returns to the vertical transfer path portion from the remaining horizontal transfer path portion to the lower portion. After traveling on the horizontal transfer path, the posture is surely held again by the guide piece 37, and the transfer is performed on the vertical transfer path between the gear device 26 and the gear device 23. The following buckets also sequentially drop the articles by the engagement members 95, and similarly return to their postures and travel. Therefore, the items are sequentially stored in the bucket and accumulated in the container.

The transport device provided with the bucket conveyor according to one embodiment of the present invention performs the above-described operations, but has the following effects.

That is, in the above embodiment, the articles are loaded in the vertical transport path of the bucket conveyor, but they can be loaded in the upper horizontal transport path, and the loading position can be set appropriately. . Further, the processing capacity can be set freely according to the rotational force of the motor 27, the number of arranged bucket conveyors, and the like.

The transport device 20 can be effectively applied, for example, as a marine product transport device, but can of course be applied to other products, for example, agricultural products such as chestnuts.

In the above embodiment, when the bucket 35 moves from the vertical transfer path to the horizontal transfer path, when the bucket 35 is inverted and when the scallops of the scallops are dropped, the buckets 35 are automatically rotated with the shafts 51 and 54 as fulcrums. Since the front wall 35c and the rear wall 35d are inclined upward, no complicated resetting means is required.

Further, since a plurality of slits S are formed in the bucket 35, water adhering to the articles drops downward from the slits S, so that the weight of the entire bucket 35 being conveyed is reduced, so that the driving The load can also be reduced. Further, even when water is sprayed from above and washed with water, water does not accumulate on the bottom. Further, since the ribs r are provided, some articles can be prevented from being caught in the slits S, and the frictional force can be reduced to smoothly discharge the articles downward.

In the above-described embodiment, the bucket conveyors are arranged in four rows as shown in FIG. 1, but may be arranged in a single row or more.

The transport apparatus having a bucket according to one embodiment of the present invention has been described above. However, the present invention is not limited to the above-described embodiment, and various modifications may be made based on the technical idea of the present invention. Is possible.

In the above embodiment, the guide piece 37 extending substantially vertically and the L-shaped chain attaching piece 38 are attached to the bucket 35. However, both of the guide pieces 37 extend substantially vertically. It is good. In that case, two vertical guide members 55 need to be provided for one bucket in the vertical transfer path portion, but the bucket 35 can be held more stably at the time of inputting an article. When the two guide pieces 37 are used, it is not necessary to form a new hole in the bucket 35, and the bucket 35 is attached by using the holes 36a, 36b, and 36c.

In the above embodiment, the engaging member 95 is formed in a rod shape and is fixed to a stationary portion such as an apparatus frame, but the engaging member 66 as shown in FIG. It can also be fixed to 65. That is,
The engaging member 66 has a connecting portion 72 provided with a rotating shaft 67, and is formed in a substantially L-shape from a short side arm portion 73 and a long side arm portion 68.

The solenoid mounting member 97 is fixed to a stationary portion such as the device frame 98. The rotation shaft 67 of the engagement member 66 is rotatably supported by a fixing plate (not shown) provided to hang down from the solenoid mounting member 97. A substantially L-shaped hook portion 70 having a cutout 69 and a rod portion 71 extending downward from the hook portion 70 are formed at the distal end of the long side arm portion 68 of the engaging member 66. The connecting portion 72 has a built-in torsion coil spring.

In the engagement member 66 thus formed, the short side arm 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 is formed. The hook 70 of the arm 68 is inserted into the small hole 61 and installed on the solenoid mounting member 97. The engaging member 66 is, as shown in FIG.
Even when an external force that rotates counterclockwise around the center 7 is applied, when the force is released, the torsion coil spring returns in the clockwise direction by the spring force of the torsion coil spring, and returns to the installed state of the torsion coil spring. When the engaging member 66 is rotated, one end 70a of the hook 70 and one end 71a of the rod 71 abut on the bottom plate 97c of the solenoid mounting member 97. Is regulated.

Such an electromagnetic solenoid 64 is connected to a controller (not shown) and is excited according to a command from the controller. In the electromagnetic solenoid 64, in a normal non-excited state, the actuator 65 is located at a broken line position in FIG.
1 is connected to the bottom plate 97 of the solenoid mounting member 97.
c. That is, it is in the upper position. When power is supplied to the electromagnetic solenoid 64 from such a non-excited state,
The actuator 65 is at the solid line position, and at the same time, the engagement member 66 is rotated to the lower position as shown. At this time, one end 70a of the hook 70 comes into contact with the bottom plate 97c of the solenoid mounting member 97, but the cushioning material 58 such as urethane rubber is adhered to the part that comes into contact with the one end 70a of the hook 70, thereby causing a collision. The generation of abnormal noise is prevented. Similarly, when the engaging member 66 is at the upper position, the rod 71
If the cushioning material 74 is adhered to a portion that comes into contact with the one end 71a, it is possible to prevent the generation of abnormal noise due to the collision at the time when the excitation ends.

As described above, the engaging member 66 is coupled to the actuator 65 of the electromagnetic solenoid 64, and the engaging member 66 is moved to the bucket 35 by the excitation and non-excitation of the solenoid 64. And can be taken selectively,
Only desired items in the bucket 35 may be dropped.

In place of the electromagnetic solenoid 64, an engaging member may be connected to a driving rod of a pneumatic or hydraulic cylinder. In this case, if the solenoid valve is connected to this cylinder and this valve is opened and closed, the same operation as in the embodiment can be performed.
