Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for supplying crushed ice which temporarily stores crushed ice to be supplied and distributed mainly to a fish box containing fresh fish to keep it cold, and discharges and supplies it as necessary.

When crushed ice crushed to an elevation angle of 20 to 40 degrees is stored in a container, it refreezes on the surfaces where the crushed ice comes into contact within a few minutes.
There are physical properties unique to ice-breaking that give it a great ice-breaking soul.

For this reason, handling is extremely difficult. There are two methods of making crushed ice: one is by crushing ice cubes each weighing several tens of kilograms, and another is a crushed ice making machine that directly produces crushed ice. However, in either case, if the ice is supplied to a fish box or the like immediately after it is crushed, it will not refreeze. No handling difficulties will occur. However, once a certain amount of crushed ice is stored in a container of some kind, and the crushed ice is discharged as needed, as mentioned above, the crushed ice becomes large chunks of crushed ice, making smooth discharge difficult. . The object of the present invention is to propose an apparatus that can smoothly discharge this secondary frozen crushed ice and supply it to the next process.

Hereinafter, a specific example in which a crushed ice supply device according to an embodiment of the present invention supplies crushed ice to a fish box will be described.

The crushed ice supply device shown in FIGS. 1 and 2 includes an ice crushing chamber for storing a required amount of crushed ice, and is installed vertically inside the wall of this ice crushing chamber 1, and transports the crushed ice to the extraction side. It includes a Reiki means 2 which also serves as a scraping conveyor, and an ice guide 3 which guides the crushed ice carried out of the ice-breaking chamber by the Reiki means 2 to a fish box.

The reiki means 2 consists of a partition plate turtle having an L-shaped cross section disposed along the wall and bottom surface of the ice-breaking chamber 1, a chain 5 that moves in synchronization with each other along both sides of the partition plate 4, and The motor that is the power source that rotates the sprocket 6 on which the chain 5 is attached in order to drive the chain 5? and a speed reducer 8, both of which are connected to the chain 5 at both ends, and are driven by the chain 6 to move upward along the surface of the partition plate turtle to lift and convey the crushed ice. . The Reiki board 9, the chain 6, and the partition plate 4 are connected to the third
This is shown in Figures 5 to 5.

As shown in FIG. 3, the partition plate 4 is provided with a chain guide 10 at its side end.The chain 5 is guided to the sprocket 6 along this chain guide IQ, and is connected to a shaft 11 that drives the sprocket 6. The roll 12 is fixed, and the reiki plate 9 is moved to a fifth position in order to transfer the crushed ice along the partition plate 4.
As shown in the figure, it is bent in a Z-shape in cross section, and has claws 13 on one front edge for scraping off frozen crushed ice, and both ends are connected to a chain 5, as shown in FIG. and moves along the surfaces of the partition plate 4 and the roll 12.

Drive wisteria 1 located on the far right in Figures 1 and 2
1 is driven by the motor 7 and the reducer 8,
Sprocket 6 fixed to drive shaft 11 is rotated.
When the sprocket 6 is rotated, the chain 5 hooked thereon is pulled and moved. As shown in Figure 3,
A roll 12 having approximately the same diameter as the subrocket 6 is fixed to the drive shaft 11, and the partition plate 4 is moved close to the roll 12. When the chain 5 is pulled, the reiki plate 9 is moved between the partition plate 4 and the partition plate 4. The sprocket is moved along the surface of the roll 12.A cross-sectional shape between the leftmost sprocket and the sprocket to the right of it is shown in FIG.

As shown in FIG. 3, the Reiki board 9, which is pulled by chains 5 on both sides, moves along the top surface of the T-partition board 4, approaching the lower edge of the wall 20 and moving horizontally.

In the diagram, the width of the wall 20 gradually becomes narrower from right to left.
As shown in the figure, the distance between the opposing surfaces of the wall 20 is
At a position narrower than the full length of the wall 2 crab, the Reiki board turtle is extended outward from the lower edge of the wall 2 crab.

As shown in FIG. 1, if the overall shape of the ice-breaking means 2 is bent into an L-shape in vertical cross section and extended from the bottom of the ice-breaking chamber to the wall surface, then the ice-breaking means 2 can be bent to form an L-shape in vertical section and extended from the bottom of the ice-breaking chamber to the wall surface. One type of Reiki method is the one that moves the crushed ice in the direction of the partition plate and carries it out using the Reiki board.At the same time as the crushed ice is raked up, the conveyor section that transports the crushed ice horizontally can transfer the crushed ice to the take-out side. It is possible to take out the

The ice-breaking chamber shown in Figure 1 is equipped with a slat conveyor blade 5 on the bottom that serves as a conveyor for conveying crushed ice to the take-out side. The slat conveyor amount 6 and the moving speed of the raking means 16 can be changed with this structure.

Therefore, since the moving speed of the slat conveyor 15 can be made slower than that of the rake means, the slat conveyor and the rake means can be driven with low horsepower. In other words, the speed of conveying the crushed ice of the slat conveyor 15 can be considerably slowed down to match the speed at which the rake means 16 scrapes the crushed ice from the sides.

Therefore, the slat conveyor 15 can slowly transport the crushed ice toward the reiki means while it is placed on top of the crushed ice without scraping the bottom of the crushed ice. Horsepower can be designed to be low. The rake means 16 scrapes the sides of the crushed ice and discharges it, but the slat conveyor 15 places the crushed ice on top without scraping it off and slowly transports it.
Therefore, it is sufficient for the slat conveyor 15 to transport the crushed ice slowly enough to press the sides of the crushed ice against the rake means 16 with a constant force. The horizontal section of the ice-breaking chamber 1 has a taper that widens in the direction of the Reiki means disposed on the extraction side, as shown in FIG. 2, so that the crushed ice in the ice-breaking chamber moves more smoothly to the extraction side. It is formed in the shape of

Furthermore, as shown in FIG. 1, if the bottom surface 17 of the ice-breaking chamber 1 is inclined downwardly toward the rake means 2, the crushed ice will more smoothly slide down the inclined surface of the bottom surface toward the rake means. In this case, as shown in FIG. 7, an ice pushing plate 18 and an air bag 19 for moving the pushing plate 18 are provided on the bottom of the ice-breaking chamber, and the pushing plate 18 is connected to a reiki means or a slat conveyor. The adjacent end, that is, the right end in FIG. 7, is pivotally connected to the ice-breaking chamber via a hinge or the like, and the air bag vine 9 is pushed under the push-up plate 18, and air is supplied to the air bag 19 to inflate it. If the structure is such that one side of the push-up plate turtle 8 is pushed up and moved so that the crushed ice placed on it slides down onto the rake means or the slat conveyor, the crushed ice can be more smoothly supplied to the rake means or the slat conveyor. .

If crushed ice is directly sent to the fish box from the reiki means 2, a certain amount of crushed ice cannot be supplied to the fish box at once.

8 and 9, an ice storage chamber 24 for storing a certain amount of crushed ice is provided at the lower end of the ice guide 23, and an ice storage chamber 24 is provided at the lower end of the ice guide 23.
A gate means 25 is provided below the ice storage chamber 24, and the gate means 25 is opened to drop the crushed ice in the ice storage chamber 24 into the fish box at once.
After the level detection means 26 detects that this amount of crushed ice is stored in the ice storage chamber 241, the gate means 2
5 and supply the stored crushed ice to the fish box. The gate means 25 shown in FIGS. 8 and 9 includes a plate-shaped on-off valve 28 that slides along a guide 27 provided horizontally at the lower end of the ice guide 23, and a cylinder 29 that drives this on-off valve 28.
By quickly opening the on-off valve 28 with this cylinder 29, the inertia of the crushed ice allows the crushed ice to fall onto the fish box in its stored state without moving in the direction of movement of the on-off valve. This structure allows the crushed ice to fall directly below while still being stored, so it has the effect of allowing the crushed ice to fall evenly into the fish box.Thus, with the ice storage chamber 24, there is variation in the conveyance of crushed ice by the reiki means. A fixed amount of crushed ice can always be supplied to the fish boxes.As shown in Fig. i, a pedestal 30 on which the fish boxes are placed is disposed below the ice guide 3,
This pedestal 30' is provided with a fish box detection means, and the gate means 25 is controlled by the detection means.

That is, the gate means is opened when the fish box is placed on the pedestal. It is also possible to use a conveyor as a cradle for the fish box, and to configure the detection means to operate and open the gate means when the fish box comes below the gate means.

By the way, as shown in FIG. 8, in order to prevent more than a fixed amount of crushed ice from being sent into the ice storage chamber 24, the level detection means 26 controls the operation of the rake means. That is, ice storage 2
When the set amount of crushed ice is stored in the level detection means 26
can also be activated to stop the operation of the Reiki means.
In order to convey crushed ice more evenly by Reiki means, as shown in FIG.
A control member 32 is provided to keep the height of the crushed ice that is lifted up on the ice cube 1 constant, and this control member 32 can be used to remove the high places of the piled up crushed ice.

This control member has claws 33 on its surface as shown in FIG.
The roll may be rotated to crush the refrozen crushed ice on the rake means. In particular, if the direction of rotation of the roll is determined so that the ice-crushing contact point of the pawl is opposite to the moving direction of the crushed ice, the relative speed between the pawl and the crushed ice will become faster and the ice-crushing effect will be further improved.Ice Guide 3 As shown in FIG. 1, the crushed ice transported by the Reiki means 2 is collided with the
Although it changes the direction of ice breaking, it also has the effect of breaking ice, especially when it collides with ice.

FIG. 12 does not have the ice storage chamber 24 and the gate means 25, and crushed ice is immediately scattered onto the fish box from the ice guide 34.

In this case, by providing the ice guide 34 with a damper 35 against which the falling crushed ice hits, it is possible to slow down the falling speed of the crushed ice and prevent the crushed ice from scattering from the fish box when it falls.
The ice-breaking supply shed device according to the present invention includes an ice-breaking chamber for storing a required amount of crushed ice, and a conveyor disposed within the ice-breaking chamber that transports the crushed ice in the ice-breaking chamber in a horizontal or almost horizontal direction and sends it to the take-out side. The ice crushing chamber has a tapered horizontal cross section that widens toward the crushed ice removal side. Therefore, the crushed ice in the ice-breaking chamber is conveyed to the take-out side by the conveyor, so that it separates from the inner surface of the ice-breaking chamber and is smoothly conveyed to the take-out side without firmly adhering to the inner surface of the ice-breaking chamber.

If the horizontal cross-section of the ice-breaking chamber is not widened toward the take-out side but is formed horizontally, the force that pulls the crushed ice attached to the inner surface of the side plate of the ice-breaking chamber away from the ice-breaking chamber when it is transferred to the take-out side is reduced. I don't accept it. Therefore, according to this shape, an extremely strong transfer force is required to transfer the crushed ice that has refrozen into ice cubes in the ice crushing chamber to the extraction side, and if the crushed ice is forcibly transferred with a strong force, the surface The inside surface of the ice-breaking chamber will be severely damaged by the crushed ice that has adhered to it, and if the inside surface of the ice-breaking chamber is made of wood, the surface of the wood will be partially peeled off by the crushed ice, resulting in countless unevenness in the form of hangnails. ``These unevenness made it even more difficult to transport ice, and the inside of the ice-breaking chamber was rapidly worn out.Also, even if the ice-breaking chamber was made of a metal plate with a smooth surface,
It is not possible to assemble the entire surface completely flat and the opposite surfaces completely parallel, and even minute irregularities make it extremely difficult to transport crushed ice, and crushed ice that has become a lump of ice receives resistance from both side plates. It does not move, only the conveyor at the bottom,
The car is being driven in a skid. The ice crushing supply combination assembly of the present invention has a very simple structure in which the shape of the ice crushing chamber is oriented toward the direction of conveying the crushed ice, making the transfer of crushed ice to the extraction side extremely smooth. Achieve critical features.
