Cake cutting device

The present invention relates to a cake cutting device, and more particularly to a cake cutting device capable of automatically setting a circular or square cake through a computer operation setting parameter and providing an equal cutting effect.

In recent years, cakes have played an indispensable role in people's daily lives. For family celebrations, company tails, and various celebrations, cakes are often used to set off the theme of celebration. Therefore, the requirements for cake cutting are relatively improved. In order to give each cake a neat and beautiful appearance, abandoning the traditional manual cutting is easy to cause the sticking between the cutter and the cut cake, affecting the quality of the cut product, and changing the mechanized cutting. Instead, it seems to have become a trend in the industry.

However, due to the structural limitations of the existing cake cutters with ultrasonic cutters, it is not possible to provide round and square shaped cakes for cutting, that is, for round or square cakes, it is necessary to replace the bulky cutting substrate, or even two Different machines, whether they are round or square cakes, often use the fingers to fix the position of the cake in order to avoid the cake being offset during cutting, but it causes the destruction of the cream on the edge of the cake, and is also cut. Before the cake must be placed in the position specified by the machine, otherwise the round cake will be uneven due to the deviation of the center of the circle, but the square cake has no center deviation, However, there is still a shift in the cake due to the thickness of the cutter itself during the cutting, which results in uneven size of the final cut cake. If so, the final cut product will be poor, in view of the existence of the above various cake cutters. After that, there is indeed a need for further improvement.

Please refer to the third to sixth figures and refer to the first and second figures for the action diagram of cutting the round cake for the creative cake cutting device. Before the cake is cut, the cover 226 is controlled to rise, and the carrier 3 is removed from the base. 21, after the user places the cake 10 to be cut on the cutting board 31, the carrier 3 is moved into position, and then the cutting unit 6 is traversed along the connecting arm 43 to the end of one side to allow the photographing above. After the lens 51 captures and locates the cake 10, the CPU module 802 of the PLC 80 automatically determines the center of the cake, and the carrier 3 moves under the cutting unit 6 and begins to cut. When cutting, the knife is cut. The plate 662 can be controlled to move left and right in the X-axis to the top of the cake to be cut on the carrier 3, and automatically determine the center of the circle, and then move up and down with the Z-axis and the R-axis to make the lower knife cut, so that each A cut falls to the center of the circle, and if so, can The cake of various uniform angles is cut according to the set parameters; once the cutting is completed, the carrier 3 is automatically moved to the front lower opening 222 of the lighting cover 22 via the Y-axis control, and the cover 226 is opened upward. The cake 10 of equal size after cutting can be taken out.

For the continuation, please refer to the seventh to ninth drawings, which is a schematic diagram of the cutting of the square cake. The CPU module 802 of the circuit device captures the cake image according to the photographing unit, and recognizes the size and position of the cake, for example, the length of the square cake. Width, in order to match the compensation value added after each cutting, to increase the distance of the cutting tool 66 to compensate for the error of the cake offset caused by the thickness of the tool. For example, the size of the square mousse cake in the eighth figure is: 570mm *370mm, the size of the 6 8-inch mousse cakes to be cut is: 180mm*180mm, two cuts can be set. The first cut is suitable for softer cakes, sponge cakes and long strips. The cake roll, because of the smaller displacement, the smaller the compensation value. As shown in the eighth figure, the first knife and the second knife cut the edges first, and the two sides of the leftmost and uppermost edges are cut and tidy before starting. Formally cut, when cutting, the blade 662 can be controlled by the left and right movement of the X axis and the Z axis up and down to make the lower knife cutting. Each cutting knife will increase the compensation value to compensate for the cake bias caused by the thickness of the tool. Shift error, if the compensation value is 5mm, then At the beginning of the three-knife, the distance moved by the titanium alloy blade 662 becomes 180+5=185 mm to offset the error of the cake offset due to the thickness of the tool, and so on; when the left and right cutting is completed, the blade 662 is controlled. The Y-axis front-rear shift control is combined with the lower-cutting of the Z-axis up and down movement, and each of the cutters increases the compensation value as described above to compensate for the error of the cake offset caused by the thickness of the cutter. The setting parameters can be automatically cut into cakes of uniform size under the cooperation of the X-axis driving assembly 71, the Y-axis driving assembly 72, and the Z-axis driving assembly 73. The second method is applicable to products with larger displacement of frozen cheesecake, frozen mousse cake, etc., which can reduce the displacement as much as possible. As shown in the ninth figure, the lower knife starts from the center and is on the X axis. The drive unit 71, the Y-axis drive unit 72, and the Z-axis drive unit 73 are mutually engaged, and are sequentially cut to the left and right and up and down, and the compensation value can be set as well. If so, the operator can select the above two different cutting methods according to the softness and hardness of the cake to reduce the offset error, and can also set the compensation for each cut, or compensate for each cut of two or three knives. The situation of the shift is determined.

In addition, the creative cake cutting device further includes an LED warning device 93 disposed on the side of the lighting cover 22 above the emergency stop switch 92, and can be used to alert the abnormal condition occurring during any operation by the sound and light effect, for example, the initialization is not performed. The emergency stop switch 92 is pressed When the cover 226 is opened, the cutting unit 6 is prohibited from moving, the position of the carrier 3 is incorrectly prohibited, the cover 226 is closed, and the like.

In summary, the creation of the cake cutting device has the following advantages:

1. With the camera automatic positioning function, the size of the square cake (including the rectangle) and the center of the round cake are recognized through the visual identification unit, and if the cake is placed out of the visual recognition range, a warning will be issued, and the cutting machine will not perform the cutting task. .

2. The X axis (the left and right movement of the blade), the Y axis (the carrier moves back and forth), the Z axis (the movement of the blade), and the R axis (the rotation of the blade), the cutting speed can be set, and the single cutting can be performed. Fully automatic cutting, can also simulate the demonstration action, which is convenient for the operator to check whether the setting is correct.

3. For the square cake, you can set the compensation value after each knife or several knives to compensate for the error of the cake offset caused by the thickness of the cutter. For the round cake, the center of the circle can be automatically determined within the range of the carrier, and each knife can be cut on the center of the circle, and the cake can be equally cut out by the set number and size.

In summary, the creation of the cake cutting device can achieve the purpose of creation, in line with the patent requirements, but the above is only the preferred embodiment of the creation, and the various modifications and changes according to the creation should still be It is included in the scope of this patent application.
