Abstract

(57) [Problem] To provide a thin ice transport device capable of reliably sending out thin ice inside an ice storage without forming a bridge inside the ice storage. SOLUTION: Two screw conveyors 2a and 2b are arranged parallel to each other at the bottom of an ice storage, and the wrapping directions of the wings of the screw conveyors 2a and 2b are formed in directions opposite to each other. The rotation directions of 2b are opposite to each other. By reciprocating the two screw conveyors 2a and 2b, fine ice can be uniformly taken out from the entire ice storage.
Bridge formation can be prevented. Further, since the screw conveyors 2a and 2b rotate so that the surfaces facing each other move upward, a force acts on the ends in the direction in which the blades of the screw scrape the thin ice. Ice can be reliably scraped off and transported.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thin ice transport device used for sequentially taking out thin ice from an ice storage for storing and storing thin ice formed by crushing ice blocks and loading the ice on a truck or the like. In particular, the present invention relates to a technique for preventing a bridge from being formed by fine ice in an ice storage.

[0002]

2. Description of the Related Art For example, it is necessary to keep fresh fish in a fish landing area or the like, and in general, seafood is mixed with fine ice and packed in a box made of foamed styrene or the like. Such fine ice is created by crushing ice blocks, and the resulting fine ice is once accumulated in an ice storage, then transported, loaded in a predetermined case, and transported by a truck or the like. Has become.

As a conventional thin ice transport apparatus, for example, as shown in FIG. 7, one screw conveyor 102 is disposed at the center of the lower surface of an ice storage 101 having a tapered lower surface, and There is known an apparatus in which thin ice 103 supplied from a conveyor is sequentially conveyed by a screw conveyor 102. In such a configuration, the thin ice 103 adheres to the tapered portion 105, and the thin ice 103
May grow and form a bridge in the ice storage 101. Therefore, a vibrator is arranged in the tapered portion 105 to generate vibration in the direction of the arrow "Y1" in the figure, and to suppress the growth of the bridge. Further, a method is employed in which a crusher 104 is disposed at an appropriate position in the ice storage 101 and the grown bridge is crushed by driving the crusher 104. However, even if such measures are taken, the fine ice 103 actually melts and adheres at the tapered portion 105, and a bridge gradually grows from this portion, and even if the crusher 104 is driven, Actually, the bridge cannot be crushed, and the fine ice 103 may not drop to the screw conveyor 102 in some cases.

[0004] As another thin ice transport device, as shown in FIG. 8, a bottom of an ice storage having a rectangular flat bottom surface is provided.
There is known a configuration in which a plurality of (five in the figure) screw conveyors 110 are arranged, and the screw conveyors 110 are simultaneously driven so that all the thin ice 103 reaching the bottom is sent out. However, also in this case, similarly to the above-described apparatus, the screw conveyor 110a arranged at the end cannot always send out the thin ice 103 at the end, and the fine ice 10
3 may grow and form a bridge,
There was a disadvantage that the thin ice 103 could not be transported as desired.

[0005] Further, for the purpose of solving such disadvantages,
An ice storage device described in Japanese Patent Publication No. Sho 62-9829 is known. The contents described in the publication are shown in FIG. 9 in which two screw conveyors 121 are connected in parallel to each other.
The thin ice 103 accumulated inside the housing 123 is carried out by rotating the screw conveyor 121 and reciprocating the bottom surface 122 in the horizontal direction. As shown in FIG. 10, the two screw conveyors 121 are formed such that the wings attached to the shaft are formed in opposite directions such that one is clockwise and the other is counterclockwise with the center part as a boundary, When the conveyor 121 is driven to rotate, the thin ice 103
Is collected at the center of the screw conveyor 121, and is sent out by the delivery conveyor 124 arranged below the two screw conveyors 121 (see FIG. 9).
They are sent out sequentially.

However, in this device for feeding out fine ice, the bottom surface 122 of the housing 123 reciprocates, so that the side of the housing 123 needs to be evacuated, which requires a large space. Further, the feeding device is configured to collect the fine ice 103 at the center of the screw conveyor 121, and the feeding conveyor 1
24, the conveyor 12
4, the thin ice 103 inside the housing 123 directly enters from above. If a large amount of the thin ice that has fallen directly enters the conveyor 124, the thin ice 103 collected by the two screw conveyors 121 cannot be collected, and the two screw conveyors 1
In some cases, the thin ice 103 collected at 21 loses a place to go, and as a result, the thin ice 103 cannot be sent out.

[0007]

As described above, in the conventional thin ice transport apparatus, a bridge may be formed inside the ice storage, and thus, the thin ice is supplied from the upper side. Regardless, there has been a problem that the fine ice does not reach the bottom surface and cannot be transported by the screw conveyor. In the case of recovering thin ice while reciprocating two screw conveyors, the inside of the transport screw conveyor located below the moving screw conveyor may be blocked by the falling fine ice. In such a case, there is a problem that the destination of the fine ice collected by the moving screw conveyor is lost, the moving screw conveyor is overloaded, and the operation stops. Was.

The present invention has been made in order to solve such a conventional problem, and an object of the present invention is to make it possible to reliably remove fine ice accumulated in an ice storage without forming a bridge. It is another object of the present invention to provide a fine ice conveying device capable of smoothly conveying.

[0009]

In order to achieve the above object, the present invention according to claim 1 of the present invention provides a thin ice for sequentially taking out and transporting thin ice accumulated in an ice storage having a rectangular bottom surface. In the transfer device, two screw conveyors that are arranged parallel to each other along one direction of the bottom surface of the ice storage and that are wound in directions opposite to each other, and a shaft of the two screw conveyors. Rotating drive means for rotating in opposite directions and rotating in a direction in which the opposing portion moves upward, a traverser for reciprocating the ice storage bottom surface by interlocking the two screw conveyors, and the two At the delivery downstream end of the screw conveyor, the screw conveyor is located at a position separated from the ice storage,
And a thin ice delivery means arranged along the reciprocating movement direction of the two screw conveyors.

According to a second aspect of the present invention, the two sides of the ice storage, which are parallel to the two screw conveyors, are formed so that the bottom portion protrudes outward. It is characterized in that the projections reciprocate on both ends widened by the projections. The invention described in claim 3 is characterized in that two side surfaces of the ice storage which are orthogonal to the two screw conveyors are open near the bottom surface.

[0011] According to the first aspect of the present invention, two screw conveyors having the wing winding directions opposite to each other are arranged side by side, and each screw conveyor is moved in the opposite direction. Rotate to. That is, 2
Since the screw conveyors of this book have opposite wing mounting directions and rotation directions, the feeding directions are the same. In addition, since the two screw conveyors operate so that the opposing surfaces rotate upward, when the screw conveyor reaches the side surface of the ice storage, the wings entrain the fine ice accumulated on the side surface. Therefore, the accumulation of fine ice on the side portion can be prevented, and the formation of a bridge from this portion can be prevented.

According to the second aspect of the present invention, since the side portions of the two screw conveyors in the reciprocating direction project outward, the reciprocating interval is slightly wider than the width of the ice storage. . Therefore, the thin ice accumulated in the corner of the ice storage can be transported by the screw conveyor without fail.

According to the third aspect of the present invention, since the lower surface of the side surface in the direction orthogonal to the two screw conveyors is notched, fine ice is formed at the corner formed by the side surface and the bottom surface. It does not accumulate and can be transported reliably by the screw conveyor.

A large amount of fine ice accumulates. The ice storage 1 is surrounded on four sides by four side plates 21a to 21d (see FIG. 1), of which the side plates 21 arranged in parallel with the screw conveyors 2a and 2b.
As shown in FIG. 3 (and FIG. 5 described later), a and 21b have a shape in which the vicinity of the bottom slightly protrudes outward. As shown in FIG. 2 (and FIG. 6 to be described later), the side plates 21c and 21d arranged orthogonal to the screw conveyors 2a and 2b have a shape in which the vicinity of the bottom is cut off. Two screw conveyors 2a and 2b are arranged to penetrate the gap formed by the notch.

The two screw conveyors 2a, 2b are:
The screw conveyors 2a and 2b are arranged side by side at a narrow distance from each other at the bottom of the ice storage 1, and the arrow "Y" shown in FIG.
While reciprocating in the direction of "2", the thin ice accumulated in the ice storage 1 is sequentially taken out from below.

One end of the two screw conveyors 2a, 2b is connected to the gear box 4, and the other end is connected to the bearing box 5, and each of the boxes 4, 5 is provided at two locations with caster portions 6 (6a, 6b). ), 7 (7a, 7b) (see FIG. 2). These casters 6 and 7 are engaged with rails 8 (8a to 8d) arranged at appropriate places on the pillar 9 that supports the outer wall of the ice storage and the entirety of the ice storage 1, and the direction of the arrow "Y2" shown in FIG. The gear box 4 and the bearing box 5 are driven by a traverse motor 11 connected by a chain 10.

That is, as shown in FIG. 1, two shafts 12 extend along the outside of the two side plates 21a and 21b.

3b and 13c are connected by a chain 14b, and one end of a shaft 12b is connected to a traverse motor 11 by a chain 10. The gear box 4 and the bearing box 5 are respectively connected to the chains 14a,
14b, the traverse motor 11
By rotating the shafts 12a, 12b
Are driven to rotate, and the chains 14a and 14b slide, so that the gear box 4 and the bearing box 5
Is also slid, so that the two screw conveyors 2a and 2b reciprocate on the bottom surface of the ice storage 1.

FIG. 4 is an explanatory view schematically showing the state of connection between the gear box 4 and the two screw conveyors 2a and 2b. As shown, the gear box 4 is connected to a drive motor 16 (see FIG. 3). ), And has a reversing machine 20 that rotates in opposite directions to each other. That is, as shown in FIG. 3, the output shaft of the driving motor 16 is connected to a first gear 17a disposed inside the reversing machine 20, and the first gear 17a meshes with the second gear 17b. Have been. Further, since the first gear 17a and the screw conveyor 2b are connected by the chain 18a and the second gear 17b and the screw conveyor 2a are connected by the chain 18b, when the driving motor 16 is rotationally driven, The first gear 17a and the second gear 17b rotate in directions opposite to each other, and the two screw conveyors 2a and 2b also rotate in directions opposite to each other.

As shown in FIG. 4, the two screw conveyors 2a and 2b are wound in the opposite directions, so that the two screw conveyors 2a and 2b rotate the conveyors 2a and 2b in opposite directions. The direction of sending out the fine ice is the same.

On the other hand, as shown in FIG.
In the lower part of the outside of c, a screw conveyor 3 for transport (fine ice feeding means) is arranged. As shown in FIG. , 2b can be transported to a desired site.

Next, the operation of the present embodiment configured as described above will be described. When the thin ice is taken out of the ice storage 1 with the thin ice accumulated in the ice storage 1, the drive motor 16 is rotated. Then, as shown in FIGS. 3 and 4, the first gear 17a and the second gear 17b are rotationally driven in directions opposite to each other,
The two scraping screw conveyors 2a and 2b are also driven to rotate in opposite directions. As the rotation direction at this time, the two screw conveyors 2a and 2b rotate so that the opposing surfaces move upward. That is,
It rotates in the direction of arrow "Y3" shown in FIG.

Next, when the traverse motor 11 is driven to rotate, the chain 14 shown in FIG.

Therefore, the thin ice accumulated in the ice storage 1 is scraped out by the scraping screw conveyors 2a and 2b and sent out to the end side (that is, outside the side plate 21c shown in FIG. 1), and the conveying screw conveyor is provided. Guided into 3. Then, by driving the transport motor 19 shown in FIG. 3 to rotate, the fine ice is sent out to the end of the transport screw conveyor 3 and is loaded in a storage case (not shown) or the like, and then is transported to the destination by a truck or the like. Delivered to

Since the two scraping screw conveyors 2a and 2b are rotating in the direction of arrow "Y3" in FIG. 4, a force is applied in a direction to scrape the thin ice accumulated at the bottom of the ice storage 1. It works and can scrape out fine ice and send it out smoothly. Further, as shown in the schematic diagram of FIG. 5, since the two side plates 21a and 21b have a configuration in which the vicinity of the bottom protrudes outward, the screw conveyors 2a and 2b may enter this portion. As a result, it is possible to reliably scrape and send out the thin ice existing at the end. Further, since the bottom portions of the two side plates 21a and 21b protrude outward, there is no problem that fine ice adheres to these portions and grows to form bridges.

As shown in the schematic diagram of FIG. 6, the side plate 21 in a direction orthogonal to the screw conveyors 2a and 2b is provided.
The c and 21d are notched near the bottom and the screw conveyors 2a and 2b are inserted into the gaps of the notches, so that the two side plates 21c and 21d are cut.
No fine ice adheres to the vicinity of the lower end of the, and no bridge grows from this portion.

As described above, in the thin ice transport device of the present embodiment, the two screw conveyors are reciprocated on the bottom surface of the ice storage 1 while rotating in the opposite directions, so that the entire bottom of the ice storage is removed. Fine ice can be scraped out and collected, and since the fine ice adhered to the corners of the ice storage 1 does not grow gradually, bridge formation can be prevented, and the fine ice can be taken out without fail. Can be transported.

The screw conveyor 3 for conveyance is disposed outside the side plate 21c of the ice storage 1, so that the thin ice accumulated in the ice storage 1 can directly enter the inside of the screw conveyor 3 for conveyance. Therefore, there is no problem that fine ice is clogged in the screw conveyors 2a, 2b, 3 and the conveyance becomes impossible.

[0028]

As described above, according to the present invention,
The two screw conveyors arranged on the bottom surface of the ice storage and having wings formed in opposite directions are rotated in opposite directions, and the two screw conveyors are reciprocated. The fine ice accumulated inside the ice storage is scraped out while moving so as to reach the entire bottom surface of the ice storage, so that the fine ice can be uniformly and reliably taken out of the ice storage and transported. Further, the two screw conveyors are driven to rotate in the direction in which the surfaces facing each other move upward (the direction of the arrow "Y3" shown in FIG. 4), so that the fine ice is crushed from the upper side to the lower side at the ends. And the thin ice can be reliably taken out even at the end.

Further, the two side surfaces parallel to the screw conveyor are formed so that the vicinity of the bottom protrudes outward, and the two side surfaces perpendicular to the screw conveyor are notched near the bottom, so that fine ice is formed in this portion. It does not adhere and grow, and the formation of bridges can be prevented. Further, since the thin ice sending means is arranged at a position separated from the ice storage, the thin ice accumulated in the ice storage does not directly fall and enter the inside of the thin ice sending means. There is no problem that fine ice is clogged inside the means and the screw conveyor and the feeding becomes impossible.
