Description

Cake Cutting Apparatus

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cake cutting apparatus, and more particularly, to a cake cutting apparatus which cuts one cake into several pieces.

Of ice cream, yogurt, cakes, fruit, puddings, dairy products and jellies that can be classified as desserts, cakes are an important food in desserts as well as in Europe and the United States.

Techniques related to the mass production of these cakes have been developed mainly in advanced countries such as Europe, USA and Japan. In Europe and the United States, mass-produced scarlet cake using refrigeration or freezing distribution is also popular as a dessert after eating.

Especially, in large restaurants such as seafood restaurants, wedding ceremonies, hotels, buffets, cafes and bakeries, various pieces of cake are served with dessert menu. These pieces of cake are cut into several pieces in the manufacturing process of cake, .

A conventional cake cutting machine for providing a piece cake has a base plate which is fed forward and backward by driving of a driving part when an operation signal is applied, and a base plate which is placed on the upper surface of the base plate and fed back and forth integrally with the base plate, A table coupled to a rotary shaft of a rotary motor coupled to a central axis of the plate to rotate the rotary motor to drive the rotary motor and to lift a cake to be cut on the upper surface; And a cutter for cutting.

Conventionally, when a square cake is cut, a square cake is raised on the table and then a signal is applied. By driving the driving unit, the base plate is advanced to move the cake placed on the table to a cutting position below the cutter, The cakes on the table are cut to a certain size by the movement of the base plate, which is moved backward at regular intervals. When the horizontal cut of the square cake is finished, the table is rotated at an angle of 90 ° to drive the rotary motor to which the signal is applied, so that the vertical cut of the square cake is prepared. Also, The backward movement of the base plate causes the cakes on the table to be cut in the longitudinal direction and then discharged to the position at the time of insertion.

Thus, in the conventional cake cutting machine, after a single cake is put in, the inserted cake is cut and waited until it is discharged, and the next cake must be put in, so that it takes a long time in the cutting process of the cake, There is a problem that the productivity is lowered.

In addition, in order to clean the cut surface of the cake during the cutting process of the cake, and to take care of hygiene, it is necessary to frequently clean the residue on the cutting edge of the cutting machine. In this cutting blade cleaning work, Since it is performed manually by wiping and wiping it on the day, there is a problem that the work efficiency is low as well as the troublesome work.

Hereinafter, the operation of the cake cutter according to an embodiment of the present invention will be described.

When the power is applied to the cake cutter, the first, second, and third trays 130 disposed at intervals of 120 degrees on the main table 110 are moved to the standby position a, the cutting operation position b, c, and the cutting portion 200 is fed to the cutting operation position b to be ready for cutting.

Then, the control unit 400 outputs predetermined data according to the shape (square, circle, roll) of the cake.

The control unit 400 receives a signal from the signal input unit 150 when a cake to be cut is placed on the tray 130 at the standby position a and a signal is applied to the signal input unit 150, A driving signal is applied to the first driving unit 111 to rotate the main table 110 at intervals of 120 degrees. This causes the tray at the standby position to be placed in the cutting operation position (b).

The sensor 143 of the second driving unit senses the first power transmission unit 120 of the tray 130 placed at the cutting operation position and applies a signal to the control unit 400.

As a result, the tray 130 is connected to the sub motor 141 of the second driving unit and becomes rotatable by the power of the sub motor, and is disengaged from the main table 110 connected by the brake 123 . That is, when the tray 130 is rotated by the driving of the sub motor 141, the main table 110 does not rotate.

The cutter 200 receives a signal from the controller 400 and rotates the cam 222 by driving the cutting motor 221 so that the link 223 coupled to the cam 222 rotates the cam 222 And the cutting blade 240 coupled to the ultrasonic transducer 230 moves up and down to move the tray 224 in the cutting operation position, The cut cake 130 is cut. At this time, when the cutting blade 240 is lowered, the ultrasonic vibrator 230 operates to apply vibration to the cutting blade 240, and the kennel blade 240 cuts the cake with the ultrasonic vibration applied.

For example, in the case of a square cake, the cutting unit 200 is transported at regular intervals to cut the horizontal direction of the rectangular cake at regular intervals, and then the tray 130 is rotated by driving the sub motor 141, The vertical direction is cut at regular intervals to cut into square pieces.

In the case of the circular cake, the tray 130 is rotated by driving the sub motor 141 to cut the cake at intervals of 90 °. Then, the cake is cut at intervals of 30 ° while changing the rotation direction of the tray 130, Cut to make the cake.

In the case of a rolled cake, the cutting unit 200 is cut at predetermined intervals to form a circular piece of cake.

Thus, the cakes can be cut into various sizes and shapes by controlling the operation of the rotary table portion, the cutting portion, and the feeding portion using predetermined data according to a square, circular, roll or other shape.

When the cutting operation is completed at the cutting operation position b, the control unit 400 stops supplying the air to the clutch 142 of the second driving unit 140 to release the coupling between the tray rotating shaft 121 and the clutch 142 , So that the brake 123 and the tray rotation shaft 121 are engaged.

At the same time, the tray 130 placed at the return position is placed in the standby position, and the cake to be cut is then raised to a waiting state for cutting.

Then, the cut part 200, which has been cut at the cutting operation position (b), is transferred to the transfer part 300 and positioned at the upper part of the cleaning part 500.

10, the washing vessel 510 of the washing section is lifted and lowered by driving the washing vessel slider section 531 with the lid 513 opened and the inlet port 511 opened.

The cutter 200 located at the upper portion of the washing tank is lowered by the driving of the upper and lower slider portions 220 to be introduced into the inlet 511 of the washing tank, When the insertion of the cutting blade 240 is detected, the lid 513 of the cleaning tank is closed and the inlet 511 is closed.

Next, the control unit 400 receiving a signal from the sensor 515 in the cleaning tank applies a signal to the cleaning liquid injector 520 to spray the cleaning liquid for a predetermined period of time. More specifically, water is sprayed in the water sprayer 521 for a preset time, and water is sprayed. Then, air is sprayed in the air sprayer 522 for a predetermined period of time to dry the water in the cutter, 523 to spray the alcohol for a preset time to sterilize the cutting portion, the cutting blade 240 is cleaned. At this time, the sprayed washing liquid, that is, water and alcohol, is drained to the drain port 512 and is collected in the water collecting tank 540.

11, when the washing of the cutting blade 240 is completed, the washing tub 510 is lowered by driving the washing tub slider 531 in a state where the lid 513 is closed. At this time, the wiper 514 provided on both sides of the lid 513 wipes away moisture, alcohol, and foreign substances from the cutting blade 240.

Then, the cutting blade 240, which is wiped with water, alcohol and foreign substances, is lifted and lowered by the driving of the upper and lower slider parts 220 by the wiper 514 of the lid, and is ready to be transported to the cutting operation position.
