Description

Technical Field

[0001] This invention belongs to the field of food processing technology, and more specifically, relates to a device for separating mooncakes from baking trays. Background Technology

[0002] After baking and cooling, the mooncakes need to be separated from the baking tray before they can be packaged in boxes.

[0003] CN206525439U discloses an automatic pancake shovel machine, including a pancake shovel device and a feeding device. The pancake shovel device includes a pancake shovel frame, a pancake shovel motor, a pancake shovel drive shaft, a belt, a telescopic mechanism, a tray, and a shovel plate. The pancake shovel motor and the pancake shovel drive shaft are both installed at one end of the pancake shovel frame, and the pancake shovel drive shaft is connected to the power output shaft of the pancake shovel motor. One end of the tray is hinged to the other end of the pancake shovel frame, and one end of the shovel plate is connected to the other end of the tray. The telescopic mechanism is installed at the other end of the pancake shovel frame and is connected to the side of the tray. One end of the belt is connected to the pancake shovel drive shaft, and the other end of the belt is connected to the other end of the shovel plate. When the feeding device transports a baking tray containing food from one end of the feeding device to the other end, the belt presses the baking tray.

[0004] The aforementioned shovel machine can also be used to separate mooncakes from baking trays. It works by having the shovel belt contact the baking tray. As the baking tray moves downwards, the mooncakes come into contact with the belt and are then transferred onto the belt, thus separating the mooncakes from the baking tray.

[0005] However, in practice, it was found that when mooncakes are arranged at intervals on the baking tray, they sometimes do not immediately move onto the conveyor belt when they touch it. Instead, they bounce back slightly under the impact of the belt. This can easily cause them to come into contact with the mooncakes behind them. After being transferred to the shovel belt, the spacing between the mooncakes decreases, which is not conducive to the subsequent feeding process, and the mooncakes may be squeezed together. Summary of the Invention

[0006] The main objective of this invention is to provide a device for separating mooncakes from the baking tray, which aims to prevent mooncakes from jumping back and to allow mooncakes to separate smoothly from the baking tray.

[0007] According to a first aspect of the present invention, a mooncake and baking tray separation device is provided, comprising a frame, a mooncake shovel unit disposed on the frame, and a baking tray conveyor line, the baking tray conveyor line being inclined, the mooncake shovel unit comprising a shovel plate located above the baking tray conveyor line and a belt disposed on the shovel plate, the shovel plate being inclined, the inclination direction of the baking tray conveyor line intersecting the inclination direction of the shovel plate, a paddle being disposed above the baking tray conveyor line, the paddle being located between the shovel plate and the input end of the baking tray conveyor line, the paddle being movable to the rear of the mooncake on the baking tray under the drive of a drive module, to prevent the mooncake from jumping backward when it touches the belt on the shovel plate.

[0008] In the aforementioned mooncake and baking tray separation device, the driving module includes a first driving component and a second driving component. The second driving component is connected to a paddle to drive the paddle to move up and down. The first driving component is connected to the second driving component to drive the second driving component to move horizontally, allowing the paddle to move closer to or away from the spatula.

[0009] In the aforementioned mooncake and baking tray separation device, both the first drive component and the second drive component are servo electric cylinders.

[0010] In the aforementioned mooncake and baking tray separation device, the drive module is a robotic arm, and the paddle is located at the end of the robotic arm.

[0011] In the aforementioned mooncake and baking tray separation device, the paddle is in a preset position before it is moved;

[0012] When the paddle is in a preset position, a first sensor is provided between the paddle and the shovel plate;

[0013] There are two first sensors, and a first detection light beam is formed between the two first sensors. The first detection light beam is located above the baking tray and is used to detect the mooncakes on the baking tray.

[0014] In the above-mentioned mooncake and baking tray separation device, a second sensor is provided between the first sensor and the spatula. There are two second sensors, and a second detection light is formed between the two second sensors. The first sensor and the second sensor are arranged horizontally side by side.

[0015] In the aforementioned mooncake and baking tray separation device, the distance between the second detection light and the spatula is greater than the maximum diameter of the mooncake on the baking tray.

[0016] In the above-mentioned mooncake and baking tray separation device, the mooncake shovel unit includes an active roller, which is located at the end of the shovel plate away from the paddle and higher than the shovel plate, and the belt is wound around the active roller and the shovel plate.

[0017] A scraper is provided below the drive roller, and the scraper contacts the belt to scrape away the residue adhering to the belt.

[0018] In the aforementioned mooncake and baking tray separation device, a detachable slag receiving tray is installed below the active roller, and the scraper is located between the slag receiving tray and the active roller.

[0019] In the aforementioned mooncake and baking tray separation device, two mooncake shovel units are arranged side by side on the frame, and there are two baking tray conveyor lines, each corresponding to one of the mooncake shovel units.

[0020] One of the above-described technical solutions of the present invention has at least one of the following advantages or beneficial effects:

[0021] In this invention, a paddle is used to assist in transferring mooncakes from the baking tray to the conveyor belt. As the baking tray moves, when a mooncake is about to touch the conveyor belt, the paddle is positioned between the front and back rows of mooncakes, behind the mooncake that is about to touch the belt. The paddle gradually moves towards the spatula. After the mooncake touches the belt, it cannot jump backward with the support of the paddle. At the same time, the paddle assists the mooncake to move forward, so the mooncake can be smoothly transferred to the conveyor belt and transported away. The mooncakes in the front and back rows will not come into contact with each other, thus achieving the separation of the mooncake from the baking tray and ensuring the quality of the separated mooncake.

[0031] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The following disclosure provides many different implementations or examples for different ways of implementing the present invention.

[0033] Example 1

[0034] Reference Figures 1 to 5 As shown, in one embodiment of the present invention, a mooncake and baking tray separation device includes a frame 1, a mooncake shovel unit 2 disposed on the frame 1, and a baking tray conveyor line 3. The baking tray conveyor line 3 is arranged at an inclination. The mooncake shovel unit 2 includes a shovel plate 21 located above the baking tray conveyor line 3 and a belt 22 disposed on the shovel plate 21. The shovel plate 21 is arranged at an inclination. The inclination direction of the baking tray conveyor line 3 intersects with the inclination direction of the shovel plate 21. A paddle 4 is provided above the baking tray conveyor line 3. The paddle 4 is located between the shovel plate 21 and the input end of the baking tray conveyor line 3.

[0035] The cake-scraping unit 2 includes a drive roller 23, which is located at the end of the shovel plate 21 away from the paddle 4 and higher than the shovel plate 21. The belt 22 is wound around the drive roller 23 and the shovel plate 21 to form a closed loop. The drive roller 23 rotates under the drive of the motor, thereby driving the belt 22 to move. A corresponding tension roller is provided on the frame 1, which is used to adjust the tension of the belt 22.

[0036] Baking tray conveyor line 3 is a chain conveyor line. The chain can attract the baking tray and move the baking tray with it.

[0037] The paddle 4 is movable under the drive of a drive module 5;

[0038] A paddle 4 is installed to assist in transferring mooncakes from the baking tray to the belt 22. As the baking tray moves, when a mooncake is about to touch the belt 22, the paddle 4 is positioned between the front and back rows of mooncakes. The paddle 4 is located behind the mooncake that is about to touch the belt 22, and it gradually moves in the direction close to the spatula 21. After the mooncake touches the belt 22, it cannot jump backward with the support of the paddle 4. At the same time, the paddle 4 assists the mooncake to move forward, so the mooncake can be smoothly transferred to the belt 22 and transported away by the belt 22. The mooncakes in the front and back rows will not touch each other, thus achieving the separation of the mooncakes from the baking tray and ensuring the quality of the separated mooncakes.

[0039] In this embodiment, the drive module 5 includes a first drive component 51 and a second drive component 52. The second drive component 52 is connected to the paddle 4 to drive the paddle 4 to move up and down. The first drive component 51 is connected to the second drive component 52 to drive the second drive component 52 to move horizontally, so that the paddle 4 moves closer to or further away from the shovel plate 21.

[0040] In use, the paddle 4 is initially in a preset position. When the mooncake is about to touch the belt 22, the second drive component 52 drives the paddle 4 to fall, allowing it to enter between the front and rear rows of mooncakes. At this point, the paddle 4 is positioned behind the mooncake that is about to touch the belt 22. Then, the first drive component 51 drives the second drive component 52 to move horizontally, making the direction of movement of the paddle 4 consistent with the forward direction of the mooncake. Therefore, the paddle 4 can always follow behind the mooncake. After the mooncake touches the belt 22, the paddle 4 continues to move forward, assisting the mooncake to transfer onto the belt 22. After this row of mooncakes has moved onto the belt 22, the first drive component 51 and the second drive component 52 work together to move the paddle 4 back to the preset position.

[0041] Furthermore, in order to ensure the accuracy of the falling position of the paddle 4, the first drive assembly 51 and the second drive assembly 52 need to have high movement precision. In this embodiment, both the first drive assembly 51 and the second drive assembly 52 are servo electric cylinders, which can control the movement of the paddle 4 precisely by using ball screws.

[0042] When the paddle 4 falls, it should land between the front and back rows of mooncakes. Therefore, it is necessary to precisely control the timing of the paddle 4's fall to ensure that it does not stick into the front row of mooncakes.

[0043] Therefore, a preset position is set, and the paddle 4 is in the preset position before it is moved;

[0044] When the paddle 4 is in the preset position, a first sensor 6 is provided between the paddle 4 and the shovel plate 21. There are two first sensors 6, and a first detection light is formed between the two first sensors 6.

[0045] A second sensor 7 is provided between the first sensor 6 and the shovel plate 21. There are two second sensors 7, and a second detection light is formed between the two second sensors 7.

[0046] The first sensor 6 and the second sensor 7 are arranged horizontally side by side;

[0047] When the baking tray moves, the mooncakes will pass through the first detection light and the second detection light in sequence. When neither the first detection light nor the second detection light detects the mooncake, it is determined that the mooncake is about to touch the belt 22. At this time, there is a certain gap between the paddle 4 and the mooncake, so it will not stick to the mooncake when it falls. If there is only one sensor, the mooncake will move slightly under the vibration of the baking tray. If it falls before the sensor detects the mooncake, it may stick to the mooncake due to insufficient gap. However, if two sensors are used for detection, the distance between the two sensors can determine the gap between the paddle 4 and the mooncake, delaying the falling time of the paddle 4 and ensuring that the paddle 4 has enough gap to fall.

[0048] Of course, the distance between the first detection light and the second detection light can also be adjusted by changing the position of the first sensor 6.

[0049] In this embodiment, the first sensor 6 is generally an infrared sensor; the two first sensors 6 are an infrared transmitter and an infrared receiver, respectively, thereby forming the first detection light.

[0050] Similarly, the second sensor 7 is also an infrared sensor.

[0051] In some other embodiments, the first sensor 6 and the second sensor 7 may also be other photoelectric sensors.

[0052] In this embodiment, the distance between the second detection light and the spatula 21 is greater than the maximum diameter of the mooncake on the baking tray; when the paddle 4 falls, the mooncake has not yet touched the belt 22, ensuring that the paddle 4 can reach behind the mooncake to provide support.

[0053] Furthermore, if residue adheres to the belt 22, the residue will prevent the mooncake from moving onto the belt 22, so it is necessary to clean the residue on the belt 22 in a timely manner.

[0054] In this embodiment, a scraper 8 is provided below the drive roller 23. The scraper 8 contacts the belt 22 and scrapes away the residue adhering to the belt 22. A slag receiving plate 9 is detachably installed below the drive roller 23. The scraper 8 is located between the slag receiving plate 9 and the drive roller 23. The residue scraped off by the scraper 8 will fall onto the slag receiving plate 9 for easy cleaning.

[0055] Based on this, the scraper 8 is used to ensure that the belt 22 is smooth, and the paddle 4 is used to assist in the transfer of the mooncakes, so that the mooncakes can be smoothly separated from the baking tray and the mooncakes can be moved onto the belt 22.

[0056] In this embodiment, two pancake-scraping units 2 are arranged side by side on the frame 1, and there are two baking tray conveyor lines 3, which correspond one-to-one with the pancake-scraping units 2. Therefore, two workstations can be arranged on one frame 1, and the equipment can be more compact.

[0057] Example 2

[0058] Reference Figure 6 As shown, it is largely the same as Embodiment 1, except that the driving module 5 is different;

[0059] In this embodiment, the drive module 5 is a robotic arm, and the paddle 4 is located at the end of the robotic arm. The robotic arm has multiple joints, which can drive the paddle 4 to rise and fall, and can also drive the paddle 4 to move along the forward direction of the mooncake. It can be flexibly controlled, and the position of the robotic arm can also be precisely controlled when moving the paddle 4.

[0060] Specifically, the robotic arm can be a 4-axis robotic arm or a 6-axis robotic arm.

[0061] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
