Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an ice conveying device attached to a cell-type ice maker that makes ice cubes for business or home use.

[Prior art]

Cell-type ice makers, for example,
It is publicly known as shown in Publication No. 38122,
There is an ice maker (sometimes referred to as an ice maker) that has a partition plate that opens downward and forms multiple cells, and an evaporator fixed to the back to cool the cells, and a water supply for ice making that corresponds to each cell. Equipped with an ice making mechanism having a water tray that has a water fountain hole and closes the cells during ice making operation and tilts downward to open the front during deicing operation, and allows ice to fall from the ice maker onto the water tray during deicing operation. Ice can be sent out from the ice maker by sliding it down.

[The problem that the idea aims to solve]

By the way, conventional cell-type ice makers have not been provided with a device that cushions ice made by the ice maker from falling onto a water tray. For this reason, even if the ice cubes formed in the cells of the ice maker are connected at the bottom, each ice cube will break into pieces when it falls onto the water tray, and the ice cubes will not be connected. It is difficult to discharge the ice cubes from the ice maker in such a state that ice cubes in such a state are convenient, for example, for bagging. In addition, if the thickness of the part that connects each ice cube is increased, each ice cube will not break apart when it falls onto a water tray, but in such a case, it is necessary to break each ice cube into pieces when using it. It is time consuming and difficult to use.

The present invention was developed by focusing on the above-mentioned problem, and its purpose is to prevent ice cubes falling from the ice maker from breaking into pieces without increasing the thickness of the parts that connect each ice cube. An object of the present invention is to provide an ice conveying device that can receive and convey ice from an ice making machine without causing any damage.

[Means to solve the problem]

The ice conveying device according to the present invention has an ice maker equipped with a partition plate that forms a plurality of cells that open downward, an evaporator fixed to the back for cooling the cells, and a fountain for supplying water for ice making that corresponds to each cell. Equipped with an ice-making mechanism that has a water tray with holes that close the cells during ice-making operation and tilt downward and open the front during de-icing operation, a large number of ice cube parts and each of these ice cube parts are formed by lattice-like slits. An ice conveying device attached to an ice maker configured to make ice in the form of a flat plate, which includes a connecting part for connecting the ice maker, and an ice conveying device that is attached to an ice maker that makes ice in the form of a flat plate. a support stand that is moved up and down by a first drive means, a moving stand that is provided on the support stand so as to be movable back and forth and can move forward and backward into the lower part of the ice maker, and that is moved back and forth by a second drive means; The third
A first detection means includes an ice receiving plate tilted by a driving means, and detects that the water tray is tilted downward after the ice making operation is completed; and a first detecting means detects that ice is placed on the ice receiving plate from the ice maker. a second detection means for detecting the ice maker, and actuating the first and second drive means based on a signal from the first detection means to move the moving table and the ice receiving plate to a position immediately below the ice maker. At the same time, the first drive means is operated based on a signal from the second detection means to move the moving table and the ice receiving plate a predetermined amount below the ice maker, and then the second drive means is operated. and a control means for moving the moving table and the ice receiving plate toward the original position, and then operating the third driving means to tilt the ice receiving plate.

[Functions and effects of the idea]

In the ice conveying device according to the present invention, when the ice making movement in the ice maker is completed and the water tray tilts downward to open the front side, the first detection means detects the downward tilt of the water tray; Based on the signal from the detection means, the control means operates the first and second drive means to move the moving table and the ice receiving plate to a position immediately below the ice maker and stop them. In this way, when ice falls from the ice maker and lands on the ice receiving plate, the second detection means detects this, and the control means operates the first drive means to move the ice based on a signal from the second detection means. After moving the table and the ice receiving plate a predetermined amount below the ice maker, the second driving means is activated to move the moving table and the ice receiving plate toward their original positions, and then the third driving means is activated to make ice cubes. Tilt the catch plate. As a result, the ice on the ice receiving plate slides down and is conveyed toward a predetermined location.

As is clear from the above explanation, in the ice conveying device according to the present invention, the ice made by the ice maker falls onto the ice receiving plate located directly below the ice maker, and the amount of ice falling is was made extremely small. The ice placed on the ice receiving plate is once moved downward by a predetermined amount and then transferred to the original position to prevent the ice from interfering with (contacting) the ice maker. The ice is transported by sliding down on the ice receiving plate at the original location. Therefore, the ice made by the ice maker can be transported to a predetermined location without breaking it.

(See Fig. 5) The threaded rod 62 is erected on one side upper part of the ice storage 61, is rotatably supported, and is adapted to be rotationally driven by an electric motor M5 at its upper end. The support stand 63 is formed to have approximately the same size as the bagged ice 10, is fixed to the lower ends of a pair of rods 67, 67, and is movable up and down along a guide 61e provided in the ice storage 61. ing. The rods 67, 67 are connected at their upper ends via a bracket 62, and are screwed onto the threaded rod 62 by a nut 68a fixed to the center of the bracket 68. Therefore, the support base 63 is moved up or down within the holding frame 64 by the rotation of the threaded rod 62.

As shown in FIG. 15, each holding frame 64 is
It is formed in a U-shape, and chains 65A, 65
A rubber flap 64a is attached to the lower end of the flap 64a so as to be tiltable upward (see FIG. 14). This flap 64a has the function of tilting upward to allow the upward movement of the support stand 63 after the holding frame 64 is replaced with an empty one, and the function of allowing the support stand 63 to move upward. A function that allows the holding frame 64 to move relative to the supporting stand 63 when the holding frame 64 is moved (replaced) with the supporting stand 63 moved down to the lower end when the ice 10 is filled, and a function that allows the holding frame 64 to move relative to the supporting stand 63. It has a function of receiving the packed ice 10 filled in the holding frame 64 and moving it together with the holding frame 64.

Chains 65A and 65B are attached to sprockets 66A to 66D, respectively, and are configured to be fed when sprockets 66A to 66D are rotationally driven by electric motor M6. Note that the rotation of the electric motor M6 is transmitted to the sprockets 66A to 66D via a reduction gear 69.

In the stocker 60 configured as described above, the support base 63 is first moved upward to the upper end within the empty holding frame 64 and then stopped. Therefore, when the bagged ice 10 slides down from the bagging device 50 and is placed on the support stand 63 through the opening 61b, the bagged ice 10 activates the switch SW14 (see FIG. 14) provided in the ice storage 61. The electric motor M5 rotates forward, the screw rod 62 rotates forward, and the support base 63 etc. move downward (after the return operation of the air cylinder AC8, the electric motor M5 rotates forward).
(It is also possible to perform the rotation in the forward direction.) Therefore, the rotation of the threaded rod 62 is detected by the counter CT provided at the upper end of the threaded rod 62.
The electric motor M5 is configured to stop after rotating by a predetermined amount. Therefore, the support stand 63 and the like move downward by a predetermined amount (an amount corresponding to the thickness of the bagged ice 10) and then stop.

The above-described operation is repeated every time the bagged ice 10 is sent from the bagging device 50 until the support base 63 moves to the lower end. By the way, the support stand 63
moves to the lower end, the switch SW15 is pushed by the bracket 68 and the sprockets 66A to 66A are moved to the lower end.
66D is rotationally driven by electric motor M6.
Therefore, the chains 65A and 65B are fed, the holding frames 64 to 64 are moved, and the holding frame 64 is replaced. Note that during this exchange, the operations of the conveying device 40 and the bagging device 50 are temporarily interrupted. Also,
When replacing the holding frame 64, replace the empty holding frame 64 with the support base 6.
3, the switch SW16 is pushed by the empty holding frame 64, and the electric motor M6
stops, and then the electric motor M5 rotates in the opposite direction, the threaded rod 62 rotates in the opposite direction, and the support base 63 and the like are moved to the upper end and then stopped. In addition,
The support stand 63 and the like are stopped by pushing the switch SW17 by the bracket 68 and stopping the electric motor M5. (See FIGS. 3 and 4) Furthermore, in this stocker 60, as shown in FIG.
A SW 18 is provided so that when all the holding frames 64 of the ice storage 61 are filled with bagged ice 10, all of the apparatus shown in this embodiment is stopped. Note that when taking out the bagged ice 10 in the ice storage 61 when all the holding frames 64 in the ice storage 61 are not filled with bagged ice 10, a take-out switch (not shown) provided in the control device 100 is activated. By pushing and moving the holding frame 64 housing the bagged ice 10 to the position of the opening/closing door 61c, the bagged ice 10 can be taken out.
