Abstract

PURPOSE:To restrict a mounting height of an ice storing device and supply some ice blocks to a transporting means at a position near the ice storing device by a method wherein some ice blocks supplied to a vertical transporting pipe from a storing space through an ice transporting means are carried up to a desired height position along the vertical transporting pipe by a screw conveyor. CONSTITUTION:Some ice blocks discharged to an ice transporting space 11b and collected at a trough member 44 under a rotational operation of the first screw conveyor 45 are transported in a horizontal discharging pipe 50 extending out of a main body 10 of an ice storing device. The ice blocks are supplied to a vertical transporting pipe 51 and then carried away upwardly by the second screw conveyor 52 disposed within the vertical transporting pipe 51. Some ice blocks carried up to an upper part are efficiently supplied to a discharging pipe 57 under a rotation of an inverse directed screw. At this time, since the third screw conveyor 60 is rotated in its normal direction, some ice blocks are discharged out of an ice discharging port 58 into a counting device 69. With such an arrangement, a mounting height of the ice storing device is restricted low and further the transporting pipe can be disposed adjacent to the main body of the ice storing device.

Description

[Detailed Description of the Invention] Industrial Application Field This invention makes it possible to keep the installation height low when installing an ice storage with an ice maker mounted on the top, and also to accommodate transportation means such as a trunk. This relates to an ice storage that can be attached.

BACKGROUND ART For example, in fishing ports, it is common to use large quantities of crushed ice blocks to freeze and preserve catches, and there is a strong demand for crushed ice blocks for this purpose. The crushed ice blocks are generally obtained by crushing ice sheets produced by a large ice maker using a crusher into small ice cubes, which are piled up in large quantities in the ice storage and stored at the bottom of the storage. The required amount of ice is transported out of the warehouse by a means for transporting ice blocks such as a screw.

At the fishing ports mentioned above, most users purchase large quantities of ice cubes at once using transportation means such as trucks, so the water outlet of ice storage installed at fishing ports is generally installed at a higher position than the truck bed. ing. -For example, by installing the ice storage upright from the installation surface by a predetermined height,
The structure is such that a truck can be driven under the bottom of the ice storage. There is also a type that releases ice cubes from a water outlet located at the bottom of the ice storage into the truck bed.

In addition, an ice block delivery pipe that communicates at its lower end with a water discharge port established at the bottom of the ice storage is arranged at an angle, and the ice blocks supplied from the water discharge port to the ice block delivery pipe are carried out by the ice transport means built into the ice block delivery pipe. Some are carried up along pipes.

Problems to be Solved by the Invention However, in the former structure, since the ice maker is installed above the ice storage, there is a drawback that the overall height of the ice storage becomes extremely high when the ice storage is installed. Also, in the latter structure,
Since the upper end of the ice block delivery pipe needs to face a position higher than the truck bed, the ice block delivery pipe extends long to the side of the ice storage. For this reason, it has been pointed out that the truck has to wait for the supply of ice cubes at a location away from the ice storage, which creates a need to secure a large space around the ice storage. In view of the drawbacks inherent in the ice storage mentioned above,
This was proposed to suitably solve this problem, and provides a means that can reduce the installation height of the ice storage and supply ice blocks to the transportation means at a position close to the ice storage. The purpose is to

Means for Solving the Problems In order to overcome the above-mentioned problems and achieve the intended purpose, the present invention provides an ice making machine on the upper part of a water storage field body with a storage space defined therein, In an ice storage warehouse that accumulates and stores a large amount of ice blocks in a storage space, and transports the ice blocks to the outside of the storage space via an ice conveying means provided at the bottom of the storage space, a vertical unloading pipe that stands vertically and communicates with the storage space at its lower part;
It consists of a screw conveyor rotatably disposed inside this vertical discharge pipe, and during the ice discharge operation, the ice cubes supplied from the storage space to the vertical discharge pipe via the ice carrying means are transferred to the vertical discharge pipe by the screw conveyor. It is characterized by being configured so that it can be carried up to a required height along the same line.

(About the crusher) At the upper part of the slat conveyor 16 on the downstream side in the running direction,
A crusher 12 is provided. As shown in FIG. 2, this crusher 12 is constructed by arranging a plurality of rectangular crusher units 39 and a plurality of screw crusher units 40 in a required arrangement in parallel in the vertical direction at required intervals. The space 11 is divided into an ice block storage space 11a inside the ice storage and an ice block storage space 11b in front of the ice storage by the crusher 12 constituted by the crushers 39 and 40.

As shown in FIGS. 4 and 5, the square crusher unit 39 has a rotatable rotating shaft 41 that extends horizontally in a direction intersecting the running direction of the slat conveyor 1G, and has protruding pins that protrude in the radial direction. 42 are planted in a suitable arrangement.

The integrated screw crusher 40 has (1) spiral blades 76 formed on a rotatable rotating shaft 43 extending horizontally in a direction intersecting the running direction of the slat conveyor 16, and (2) the blades 7G. A large number of protruding pins 42 that protrude in the radial direction at positions where they do not interfere are arranged in an appropriate arrangement. In the embodiment, the screw crusher unit 40 and the rectangular crusher unit 39 are arranged alternately in stages, thereby forming the crusher 12 as a whole. The radial protrusion length of the blades 76 and the protrusion length of the protrusion pin 42 in the screw crusher unit 40 are set to be approximately the same as shown in FIG. 5, and when the crusher unit 40 rotates, The blade 76 and the protruding pin 42 are both configured to be able to break up the ice mass 22.

Each crusher unit 39 that constitutes the crusher 12
, 4.0 are rotationally driven in the same direction by a drive motor (not shown), and the ice blocks crushed by the crusher 12 are discharged from between the respective crusher units 39, 40 to the ice block carrying-out space 11b side. (see Figure 2), and the ice blocks 22 that adhere to the surface of the slat conveyor 16 are
If the operation continues without being scraped off by the crusher 12, there is a risk that the running of the conveyor 16 will be hindered. Therefore, it is possible to set the number of protruding pins 42 in the rectangular crusher unit 39 disposed at the lowest stage of the crusher 12 to be large so that the ice blocks 22 stuck to the surface of the slat conveyor 16 can be reliably scraped off. Recommended.

(Regarding the ice scraping device for the slat conveyor) At the bottom of the ice block delivery space 11b side, as shown in FIGS. 6 and 7, a gutter member 44 having a substantially υ shape in cross section is provided.
It extends over the entire length of the slat conveyor 16 in the width direction (direction intersecting the traveling direction), and all ice blocks crushed by the crusher 12 fall into a gutter member 44 and are collected therein. Inside this gutter member 44, a first screw conveyor 45, which will be described later, is rotatably disposed.
The ice blocks collected in the gutter member 44 are carried out of the warehouse via the conveyor 45.

As shown in FIG. 6, the side plate 44a of the gutter member 44 that faces the slat conveyor 16 extends below the folded portion of the conveyor 16 (the location where the sprocket 33 is disposed), and its open end is connected to the conveyor 16. close to the surface. Then, the side plate 44a and the slat conveyor 16

The length of this screw 46 is set longer than the width of the slat conveyor 16, and the outer peripheral end of the spiral blade 46a is brought close to the surface of the conveyor 16. That is, the ice that has adhered to the surface of the slat conveyor 16 without being crushed by the crusher 12 is removed by the screw 46.
All of the material is scraped off by rotating it.

Further, the scraped off adhering ice is collected by the gutter member 44 and carried out of the warehouse.

(Regarding the water conveyance device) As shown in FIG. 1, a first screw conveyor 45 constituting the ice conveyance device 48 is horizontally rotatable inside the gutter member 44 disposed at the bottom of the ice block conveyance space 11b. It is arranged. One end of the first screw conveyor 45 extends outward from the side wall 10a, and a first motor 47 is connected to the end via a linking means 49 such as a sprocket chain. It is configured to rotate in the normal rotation direction. Further, the other end of the conveyor 45 is connected to an opening 10b formed in the other side wall 10a.
It extends horizontally outside the warehouse through the

Outside the side wall 10a where the opening 10b is formed, a horizontal unloading pipe 50 communicating with the ice block unloading space 11b via the opening 10b extends horizontally for a predetermined length. Then, inside the horizontal carrying-out pipe 50, an ice block carrying-out space 11b is provided.
The first screw conveyor 45 disposed in is facing horizontally.

Therefore, when the first screw conveyor 45 is rotated, the ice cubes collected in the gutter member 44 are conveyed through the horizontal discharge pipe 50 as the conveyor 45 rotates, and are transferred to the vertical discharge pipe 51, which will be described later. Supplied.

As shown in FIG. 1, a vertical carry-out pipe 51 is installed adjacent to the ice storage main body 10, and the horizontal carry-out pipe 50 is connected to the lower part of the vertical carry-out pipe 5.

A second screw conveyor 52 is rotatably disposed inside the vertical discharge pipe 51, and the second screw conveyor 52 is driven by a second motor 54 fixed to the vertical discharge pipe 51 via a bracket 53. It is configured to rotate in the normal rotation direction. Therefore, the ice blocks supplied to the lower part of the vertical discharge pipe 51 via the first screw conveyor 45 are carried up to the upper part of the vertical discharge pipe 51 by the rotation of the second screw conveyor 52. In addition, a vertical unloading pipe 51 is installed in the vicinity of the water storage source body 10, and the vertical unloading pipe 51 carries the ice cubes to a higher position than the loading platform of the 1-rack 70, which will be described later. 70 can be attached to the side of the ice storage main body 10. Thereby, the ice storage main body 10 can be installed directly on the installation surface, and there is no need to secure a large space around the ice storage main body 10.

Here, since the frictional resistance between the ice blocks and the second screw conveyor 52 is extremely small, it is difficult to transport the ice blocks only by rotating the conveyor 52. Therefore,
In the embodiment, as shown in FIG. 9, the second screw conveyor 52 is eccentrically arranged inside the vertical discharge pipe 51, and is protruded inward by a predetermined length on the inner wall surface of the vertical discharge pipe 51. The baffle member 55 extends over substantially the entire length of the discharge pipe 51 in the longitudinal direction. That is, the ice blocks supplied to the lower part of the vertical discharge pipe 51 are transferred to the second screw conveyor 52.
It moves along the inner wall surface of the discharge pipe 51 as the pipe rotates, and is pushed upward when it comes into contact with the baffle member 55. Thereby, smooth transportation of ice blocks is achieved.

Note that, as shown in FIG. 8, only one turn of the screw 56 in the opposite direction is disposed at the top of the second screw conveyor S2. This reverse screw 56 functions to efficiently supply the ice cubes carried up by the second screw conveyor 52 toward a discharge pipe 57, which will be described later.

A horizontal discharge pipe 57 is provided above the vertical discharge pipe 51.
They are communicatively connected at approximately the center in the longitudinal direction. This discharge pipe 57 is as shown in FIG.

A water discharge port 58 is connected to one end in the longitudinal direction, and the other end of an ice block collection v59 whose one end communicates with the ice block discharge space 11b of the ice storage main body 10 is connected to the other end ( (See Figure 2). Furthermore, a third screw conveyor 60 is rotatably disposed inside the discharge pipe 57, and the third screw conveyor 60 is rotated in forward and reverse directions by a third motor 61 disposed on the side wall 10a of the ice storage main body 10. It is configured to rotate in the direction. That is, the ice cubes supplied from the vertical discharge pipe 51 to the discharge pipe 57 are discharged to the outside through the water discharge port 58 by rotating the third screw conveyor 60 in the normal rotation direction. Also 5th 3rd
When the screw conveyor 60 is rotated in the reverse direction, the ice blocks in the discharge pipe 57 are returned to the ice block discharge space 11b via the ice block collection pipe 59. and,
The ice blocks collected in the ice block carry-out space 11b are carried out of the warehouse in the first ice discharge operation.

Further, an opening/closing plate 78 is disposed at the opening of the water discharge port 58 so as to be openable and closable, and an opening/closing plate 79 is disposed at the opening of the ice recovery pipe 59 facing into the water storage source body 10 so as to be openable and closable. That is, when ice blocks are being discharged to the outside through the water discharge port 58, the opening/closing plate 59 of the ice block collection pipe 28 is closed to prevent outside air from flowing into the refrigerator. When collecting ice cubes into the refrigerator, open/close plate 78 of water outlet 58
is configured to close and prevent outside air from flowing into the refrigerator.

It should be noted that a horizontal discharge pipe 50. The vertical discharge pipe 51 and the discharge pipe 57 are each covered with a heat insulating material (not shown).

(Regarding the rotating mechanism of the water discharge port) The water discharge port 58 communicating with the discharge pipe 57 is rotatably supported by a bracket 62 disposed on the vertical discharge pipe 51 via a hinge 63, as shown in FIG. A chain 64 is wrapped and fixed around the outer periphery of the water outlet 58. Further, a shaft 65 extending parallel to the vertical discharge pipe 51 is rotatably disposed on the discharge pipe 51 via a bracket 66, and a sprocket 67 disposed at the upper end of this #65 meshes with the chino 64. ing. That is, by rotating a handle 68 disposed at the lower end of the shaft 65 in a predetermined direction, the direction of the water discharge port 58 can be varied under the action of engagement between the sprocket 67 and the chino 64.

(About the measuring device) Below the water outlet 58, as shown in FIG. At the point when
It is supplied to a truck 70 that has entered below the weighing machine 69. This measuring device 69 is configured to detect that the weight of the ice blocks supplied through the water outlet 58 has reached a preset weight and control the operation of the three motors 47, 54, and 61. has been done.

That is, when the meter 69 detects a fixed amount, the first motor 47. Second
Motor 54 and third motor 61 are stopped. Also,
At this time, the slat conveyor 16 and crusher 12
is also stopped at the same time, and the ice storage main body 10 (ice block removal space 1
Stop the removal of ice blocks from 1b). Next, after a delay of a predetermined time (approximately 1 to 2 seconds), the third motor 61 is first activated to rotate in the reverse direction, and the second motor 54 is activated with a further delay of 1 to 2 seconds. As a result, the ice blocks remaining in the vertical carry-out pipe 51 and the discharge pipe 57 are returned to the ice block carry-out space 11b, and the ice blocks remaining in the vertical carry-out pipe 51 and the discharge pipe 57 are returned to the main carry-out route (the vertical carry-out pipe 51 and the discharge pipe 57) arranged outside the water storage source main body 10. It is designed to prevent ice cubes from remaining inside. Then, after a predetermined period of time has elapsed, the second motor 54 and the third motor 61 are stopped, and the - ice farm operation is completed. In addition, by detecting the quantitative amount by the measuring device 69, the time from when the second motor 54 and the third motor 61, which have been stopped once, are restarted to when they are stopped again, is determined by the amount of ice remaining in the vertical unloading pipe 51. All ice cubes are set in advance at times at which they can be returned to the ice removal space 11b.

Here, when starting the ice block discharge operation, if the three motors 47, 54, 61 are started at the same time, the horizontal unloading pipe 5
There is a possibility that ice blocks may become clogged at the connection between the vertical discharge pipe 51 and the vertical discharge pipe 51 and the joint between the vertical discharge pipe 51 and the discharge pipe 57. Therefore, in the embodiment, when starting the ice block discharging operation, the third motor 61 → the second motor 54 → the first motor 47 are started in this order, and each start is set to be delayed by about 1 to 2 seconds. (See Figure 12). Further, the slat conveyor 16 and the crusher 12 are operated with a delay of about 1 to 2 seconds after starting the first motor 47.

Note that the amount of ice blocks released from the ice storage main body 10 is
Instead of controlling with the measuring device 69, for example, the amount of ice cubes released from the water storage source main body 10 can be controlled by the user operating a start button and a stop button (none of which are shown). You may. In this case, when the user operates the stop button, the third motor 6 is rotated in the reverse direction, and the excess ice blocks remaining in the carry-out route are collected.

(Regarding means for detecting the amount of ice blocks carried out by the first screw conveyor) Here, when the amount of ice blocks carried out by the first screw conveyor 45 increases, the opening 10b or the horizontal carrying pipe 5
There is a risk that ice blocks may become clogged inside the container and prevent smooth conveyance. Therefore, in the embodiment, the opening 10 of the ice storage main body 10 is
A detection means 71 is disposed at a position close to b, and the detection means 71 is configured to monitor the amount of ice blocks carried out by the first screw conveyor 45.

As shown in FIG. 11, a detection plate 72 is swingably suspended above the first screw conveyor 45, and
A movable plate 73 is disposed below the detection plate 72 so that its height can be adjusted freely. Further, an actuation piece 74 is protruded from the upper part of the detection plate 72, and a lever 75a of an ice detection switch 75, which is fixed relative to the upper part of the first screw conveyor 45, always faces the movement locus of the actuation piece 74. electrically closes the ice detection switch 75.

However, when more ice blocks than the set amount are conveyed by the first screw conveyor 45, the ice blocks contact the movable plate 73 and rotate it, causing the actuating piece 74 to separate from the lever 75a of the ice detection switch 75. , the switch 75 is opened.

At this time, the slat conveyor 16 and the crusher 12 are stopped, and the ice block carrying out space 11 is stopped.
Stop the release of ice blocks to b. Note that when the number of ice cubes in the ice cube delivery space 11b decreases due to the rotation of the first screw conveyor 45, the ice detection sinker 5 returns to its original state and repeats the operation of operating the slat conveyor 16 and crusher 12 again. ing.

Function of the embodiment Next, the function of the ice storage according to the present invention will be explained. 1st
In the ice storage shown in the figure, when the ice making operation in the ice maker 13 is completed, the generated sheet ice falls and is crushed by a crusher (not shown), forming a large number of ice blocks and storing the ice blocks in the ice storage main body 10. It is deposited and stored in the space 11a. At this time, the ice cubes falling from the ice maker 13 through the chute 14 are as follows.

The amount distributed by the leveling device 15 comes into contact with the plate 23, scatters from side to side, and accumulates approximately evenly in the ice block storage space 11a.
Also. The ice blocks released into the ice block storage space 11a are stored in the space 11a to a predetermined level, and each ice block solidifies into a large block. In addition, the ice storage body 1o
As described above, the inside of the slat conveyor 16. crusher 1
2 and the water transport device 148 have stopped driving and are in a standby state.

Next, when it is necessary to take out a predetermined amount of ice blocks stored in the ice storage main body 10, the slat conveyor 16° crusher 1 is activated by operating a water release button (not shown).
2 and the water transport device 48 are started according to the timing chart shown in FIG.

As a result, the ice block group 22 stored in the ice block storage space 11a slowly moves forward as the slat conveyor 16 runs, and its front end comes into contact with the crusher 12. At this time, since the crusher 12 is rotating, the protruding pins 49 and 40 protruding from each crusher integrally 39 and 40
The ice block group 22 is broken down by the ice block removal space 11b.
is released.

At this time, as shown in FIG. 5, the ice block group 22 is crushed by the blades 76 of the screw crusher unit 40, so that the ice block group 22 transported by the slat conveyor 16
The downstream side face is scraped not only over the portion corresponding to the protruding pin 42 but also over substantially the entire length in the longitudinal direction. That is, the rotating shaft 41 of each crusher unit 39.40
．． The ice block group 22 is not pressed against the shaft 4
1.43 can prevent accidents such as bending or damage. Furthermore, excessive loads are not applied to the drive motors of the slat conveyor 16 and crusher 12.

Here, the slat conveyor 16 often passes through the location where the crusher 12 is disposed with some of the ice blocks 22 that have not been crushed by the crusher 12 remaining attached to the conveyor surface. However, since the screw 46 facing inside the gutter member 44 and disposed close to the slat conveyor 16 is rotating, the water adhering to the surface of the slat conveyor 16 is removed by the screw 46 as shown in FIG. Will be scraped off. The scraped adhering water is collected in the gutter member 44.

In addition, the three motors 47, 54, and 61 rotate in the forward rotation direction, and first, under the rotational action of the first screw conveyor 45, water is discharged into the ice removal space 11b and collected in the gutter member 44. The ice cubes are transported through a horizontal discharge pipe 5o extending outside the ice storage main body 10. This ice block is supplied to the vertical discharge pipe 51 and then carried upward by a second screw conveyor 52 disposed inside the vertical discharge pipe 51. As shown in FIG. 8, since a reverse screw 56 is disposed at the top of the second screw conveyor 52, the ice cubes carried up to the top are efficiently transferred to the discharge pipe 57 by the rotation of the reverse screw 56. supplied.

At this time, the third screw conveyor 60 disposed inside the discharge pipe 57 is rotating in the forward direction, so the ice cubes supplied to the discharge pipe 57 move to the left in the discharge pipe 57 (see Fig. 1). ). The ice block is then discharged into the measuring device 69 via the water discharge port 58.

When the three screw conveyors 45, 52, and 6Q continue to rotate in the normal rotation direction and a predetermined amount of ice blocks carried out from the ice storage main body 10 are supplied to the measuring device 69, the measuring device 69 detects a quantitative amount, and as shown in the 12th time, the slat conveyor 16. The operations of the crusher 12 and three motors 47, 54, 61 are stopped. As a result, each screw conveyor 45, 52, 60 stops, and the removal of the ice blocks from the ice storage main body 10 is stopped.

Next, the third motor 61 is started and rotates in the reverse direction, and under the reverse action of the third screw conveyor 6o,
The ice blocks remaining in the discharge pipe 57 move to the right (
(in FIG. 1), and is returned into the ice block carrying-out space 11b via the ice block collection pipe 59. Further, the second motor 54 is started after a predetermined time delay and rotates in the normal rotation direction.

The ice blocks remaining in the vertical discharge pipe 51 are conveyed toward the discharge pipe 57 by the second screw conveyor 52. Therefore, the ice blocks conveyed from the vertical carry-out pipe 51 to the discharge pipe 57 are also returned into the ice block carry-out space 11b. After a predetermined period of time has elapsed, the second motor 54 and the third motor 61
has stopped.

The first ice release operation is completed.

That is, when the first screw conveyor 45 is stopped due to quantitative detection by the measuring device 69, all of the excess ice remaining in the vertical discharge pipe 51 and the discharge pipe 57 is transferred to the water storage source main body 1.
Returned to 0. Therefore, it is possible to prevent the ice blocks from solidifying in the carry-out route and damaging the screw conveyor, or to prevent the ice blocks remaining in the carry-out route from melting and becoming waste.

The ice cubes supplied to the scale 69 are discharged and supplied to a truck 70 whose loading platform faces below the scale 69, as shown in FIG. At this time, since the vertical unloading pipe 51 is disposed close to the ice storage main body 10, the truck 7
o is a position close to the ice storage main body 10, and can wait for the supply of ice cubes. In other words, since a large space around the ice storage is not required, the land can be used effectively.

Effects of the Invention As described above, according to the ice storage according to the present invention, an ice block delivery pipe is vertically installed and communicates with the ice block storage space defined inside the ice storage main body, and The supplied ice cubes are carried up along a discharge pipe by a knee conveyor. That is, with the ice storage main body installed directly on the installation surface, ice cubes can be carried up to a higher position than the loading platform of a transportation means such as a trunk, so the installation height of the ice storage can be kept low. Moreover, since the ice block carrying pipe is vertically arranged, the carrying pipe can be placed close to the ice storage main body, which has the advantage that a large space around the ice storage is not required.
