Description

The proposed utility model relates to equipment for cutting confectionery products and is used for quick and high-quality cutting of cakes and cheesecakes into equal pieces and at the same time laying paper to the cut point.

Industrial devices designed for slicing confectionery products are known from the prior art (see patents RU No. 2101957 dated 03/02/94, No. 2420963 dated 11/13/2009, IPC A21C15/04). The listed devices are mechanical, the cutting process is completely controlled by the operator.

The closest to the proposed technical solution in terms of technical essence and achieved result is a semi-automatic pneumatic machine for slicing cakes and cheesecakes (see patent RU No. 217 346U1 dated 12/08/2022, IPC A21С15/04). We select the machine according to the specified patent as a prototype. The machine allows you to ensure high quality cutting of round confectionery products in a semi-automatic mode.

A disadvantage of the known technical solution is low productivity and increased operator labor costs when cutting cakes and cheesecakes. These disadvantages are a consequence of the machine operating in semi-automatic mode.

The objective of the claimed utility model is to develop the design of an automatic device for cutting cakes and cheesecakes, which makes it possible to increase the productivity of cutting pieces lined with paper in a fully automatic mode.

The technical result is to increase productivity while reducing operator labor costs.

The problem is solved in that a device for cutting cakes and cheesecakes, containing a frame, a retractable work table, a turntable with a rotation drive, a cake cutting knife, a knife moving mechanism mounted on the frame, a paper tray, is additionally equipped with a table extension drive and a drive feeding paper into the tray, as well as a knife for cutting paper, equipped with a movement drive, and the table extension drive and the paper feed drive are made in the form of a pneumatic cylinder and a stepper motor.

Figure 1 shows a diagram of a device for cutting cakes and cheesecakes.

The following designations have been introduced: 1 – frame, 2 – retractable work table, 3 – rotary table, 4 – rotary table rotation drive, 5 – retractable work table drive, 6 – paper tray, 7 – cake cutting knife, 8 – travel drive cake cutting knife, 9 – paper feed mechanism, 10 – drive for moving the paper cutting knife, 11 – paper cutting knife, 12 – paper, 13 – control system, 14 – cake.

The device for slicing cakes and cheesecakes is made in the form of a frame 1 with guides on which a retractable work table 2 is installed, connected to a turntable 3 equipped with a rotation drive for the turntable 4. Drive 4, consisting of a stepper motor and a gearbox, is mounted on the bottom of the retractable work table table 2. Extension of the work table 2 and the associated rotary table 3 is ensured by the drive of the retractable table 5, consisting of a pneumatic cylinder connected to frame 1.

On the frame 1 there is a tray 6 for feeding paper, equipped with a slot for through movement of the knife 7 for slicing the cake. The cake cutting knife 7 has the ability to move vertically due to the cake cutting knife movement drive 8, which consists of a pneumatic cylinder, linear and articulated movement mechanisms. The mechanism 9 for feeding paper into tray 6 is made in the form of a pressing drum and a drive drum, the rotation of which is carried out by a drive consisting of a stepper motor and a gearbox. The paper cutting knife 11 is equipped with a drive for moving the knife 10, consisting of pneumatic cylinders and linear and articulated movement mechanisms. Paper 12 in the form of two rolls is placed on a holder mounted on the frame 1 at the rear of the machine, and on the side of the frame there is a control system 13 that ensures the machine operates in automatic mode.

The machine operates as follows.

The machine is connected to power supply and compressed air systems. A roll 12 with food paper is placed on a holder and sent through a paper feed mechanism 9 into a paper tray 6. The power switch is turned to the “On” position, power is supplied to the HMI panel of the control system 13. The operator sets the parameters (recipe) for cutting a cake or cheesecake. After setting the settings and confirming them, a warning sound is given about the extension of the working table 2. The extending working table 2 takes the position of loading the cake. The operator places the cake on the turntable 3 and presses the “Start” button on the control system panel 13. The pneumatic cylinder of the table extension drive 5 moves the retractable work table 2 and the rotary table 3 with the cake into the working area of the machine. Next, the software algorithm control system 13 feeds paper into tray 6 using drive and feed drums. After unwinding a certain length of paper, the drive drum stops and a command is sent to the drive 10 of the knife 11 for cutting the paper. The paper cutting knife 11 makes a vertical reciprocating movement with the help of pneumatic cylinders of the paper cutting drive 10. After cutting the paper, a command is received to move the knife 7 to cut the cake. The cake cutting knife 7 pulls the cut sheets of paper through the slot of the paper tray 6 and cuts the cake. Knife 7 for cutting the cake returns to its original state - to the upper position. The paper folded into 2 parts remains in the cut of the cake. After the knife 7 returns to its original state, the drive of the turntable 3 rotates the cake 14 at a certain angle, depending on the specified number of pieces in the system settings. The machine cycle is repeated until the cake is completely cut. At the end of the full cycle, a sound warning is given about the extension of the working table 2. The cutting process is controlled by the operator and if an abnormal situation occurs, the operator performs an emergency stop by pressing the “Emergency” button.

When the device is finished operating, turn off the power supply and stop the compressed air supply.

The installed program in the control system settings allows you to change the number of pieces to be cut and the laying of paper between the cuts, ensuring compliance with the requirements of sanitary and hygienic standards.

The proposed device for cutting cakes and cheesecakes ensures fast and accurate cutting of the cake into equal pieces while simultaneously installing separating paper in automatic mode without intermediate operator intervention. At the same time, the labor intensity of cutting is significantly reduced, productivity and speed of delivery of products to the consumer are increased.
