Description

Technical Field

[0001] This invention relates to the technical field of industrial manufacturing, and in particular to a control method for a double-layer feeding device. Background Technology

[0002] With the acceleration of manufacturing, multi-layer feeding devices are widely used in food production plants and metal processing lines. Manufacturers are increasingly emphasizing the efficiency of multi-layer feeding devices in food transfer processes. However, existing multi-layer feeding devices are slow in transporting materials. Currently, each product to be baked is manually picked up and placed into its corresponding oven. This manual operation often involves touching the food's surface, potentially affecting the baking yield. Multiple workers frequently handling numerous neatly arranged food items consume significant manpower, making the food transfer process overly complex. Manual transfer of food significantly increases production time, and the process of manually handling baked food can leave traces on the surface, impacting the overall product quality. Currently, existing multi-layer feeding devices on the market suffer from issues with the smooth transport and output of baked products. Summary of the Invention

[0010] The baking schedule is used to determine whether each product placed inside the double-layer feeding device meets the preset discharge conditions; the baking schedule includes the baking time record of all products placed inside the double-layer feeding device.

[0011] If a product meets the discharge conditions, the baking layer of the product that meets the discharge conditions sends a first discharge instruction to the elevator located at the end away from the transfer platform.

[0012] A second discharge command is sent to the elevator located near one end of the transfer platform based on the product transfer and placement information.

[0013] Determine whether the product transfer and placement information meets the feeding conditions;

[0015] The control method for the aforementioned double-layer feeding device, wherein the discharge conditions include a baking time threshold, and the determination of whether each product placed inside the double-layer feeding device meets the preset discharge conditions based on a preset baking time schedule includes:

[0016] Based on the baking time records of each product in the baking schedule, obtain the baking duration corresponding to the product with the longest baking time from the baking schedule;

[0017] Determine whether the baking time corresponding to the current product exceeds the baking time threshold, thereby determining whether the current product meets the discharge conditions.

[0018] In the control method of the above-mentioned double-layer feeding device, the transfer platform is a double-layer structure, the lower end of the double-layer structure is fixedly connected to a first support, the lower end of the first support is in contact with the ground, and the other end of the first support is flush with the transport window of the elevator.

[0019] In the control method of the above-mentioned double-layer feeding device, a second support is fixedly connected to the upper end of the first support, and the second support is horizontally arranged.

[0020] In the control method of the above-mentioned double-layer feeding device, the width of the second support is smaller than the width of the first support, and the height of the second support is greater than the height of the first support.

[0021] In the control method of the above-mentioned double-layer feeding device, a transport window is provided on the side of the lifting frame facing the double-layer structure, and the width of the transport window is the same as the width of the second support.

[0022] In the control method of the above-mentioned double-layer feeding device, the height of the upper conveyor belt of the second transfer platform is the same as the height of the lifting frame of the elevator.

[0023] In the control method of the above-mentioned double-layer feeding device, the height of the cooling conveyor belt is the same as the height of the bottom end of the lifting frame of the elevator.

[0024] In the control method of the above-mentioned double-layer feeding device, the upper oven, the middle oven and the lower oven are arranged in parallel and fixed to the inner wall of the baking box from top to bottom.

[0025] This invention discloses a double-layer feeding device, comprising: a baking oven, a transfer platform, and two elevators disposed on both sides of the baking oven.

[0036] Please see Figure 1 , Figure 2 as well as Figure 3 As shown in the figure, a control method for a double-layer feeding device in this invention includes: a baking oven 1, a transfer platform 3, and two elevators 2 disposed on both sides of the baking oven 1. The transfer platform 3 includes: a first transfer platform 4 and a second transfer platform 5, with the second transfer platform 5 mounted on the lower end of the first transfer platform 4.

[0037] Both the first transfer platform 4 and the second transfer platform 5 are equipped with a conveyor belt 6. A detection sensor 9 is mounted on each end of the drive shaft of the conveyor belt 6. The detection sensor 9 is used to identify whether a product 10 enters the transport window 7 of the elevator 2.

[0038] The baking oven 1 has an internal cavity, and multiple ovens with a layered structure are installed inside the cavity. Each oven is arranged in the cavity of the baking oven 1 from high to low. The oven includes an upper oven 11, a middle oven 12 and a lower oven 13. A cooling conveyor belt 14 is also provided on the side of the lower oven 13 that is close to the ground.

[0039] The lifting platform 2 includes: a time controller (not shown in the figure), a lifting frame (not shown in the figure), and a vertical box 8 slidably connected to the lifting frame. The time controller is electrically connected to the transfer platform 3. The lifting frame is a hollow support with a rectangular vertical cross-section. Multiple vertical sliders are provided on the outer side of the vertical box. The vertical sliders are slidably connected to the vertical slide rails provided on the lifting frame. The vertical box 8 is driven by a motor built into the lifting frame to move vertically along the direction of the vertical slide rails. The vertical box 8 has a hollow cavity in the horizontal direction along one side of the first transfer platform 4. The width of the hollow cavity in the vertical box 8 is equal to the width of the first transfer platform 4. The height of the hollow cavity in the vertical box 8 is the same as the gap between the first transfer platform 4 and the second transfer platform 5.

[0040] Specifically, in this embodiment, the double-layer feeding device includes: a baking oven 1, a transfer platform, and two elevators 2 disposed on both sides of the baking oven 1. The transfer platform includes: a first transfer platform 4 and a second transfer platform 5. The second transfer platform 5 is mounted on the lower end of the first transfer platform 4. Both the first transfer platform 4 and the second transfer platform 5 are equipped with conveyor belts 6. A detection sensor 9 is mounted on each end of the drive shaft of the conveyor belt 6. The detection sensor 9 is used to identify whether a product 10 enters the transport window 7 of the elevator 2. The baking oven 1 has an internal cavity, and multiple layered ovens are assembled inside the cavity. Each oven is arranged in descending order of height within the cavity of the baking oven 1. The ovens include an upper oven 11, a middle oven 12, and a lower oven 13. A cooling conveyor belt 14 is also disposed on the side of the lower oven 13 closest to the ground. In one embodiment, the conveyor belts 6 of the first transfer platform 4 and the second transfer platform 5 can simultaneously perform forward and reverse transmission. Platform 5 is positioned at the top of the first transfer platform 4. The output port of the conveyor belt 6 of the first transfer platform 4 is parallel to the lower end of the transport window 7 of the elevator 2. The output port of the conveyor belt 6 of the second transfer platform 5 is close to the upper end of the transport window 7 of the elevator 2. This configuration forms a double-layer feeding device. The entire feeding device outputs product 10 to one end of the transport window 7 of the elevator 2. The lifting frame of the elevator 2 is vertically raised and lowered to the corresponding level of the oven, facilitating the transfer of the corresponding product 10 to the corresponding level of the oven. This allows for fully automatic management of the oven by the user, eliminating the need for manual feeding. Product 10 can be placed directly on any transfer platform and transferred by the conveyor belt 6 to the corresponding level of the oven. The timer inside the oven determines whether product 10 has reached the preset baking time. The oven is then transferred by the elevator 2 to the baked product 10, thereby improving the baking efficiency of product 10 and facilitating automated management of the baked products, thus improving the overall baking efficiency of the device.

[0041] Furthermore, the lifting platform 2 includes a lifting frame and a time controller electrically connected to the lifting frame. The time controller is electrically connected to the transfer platform 3. The lifting frame is a vertical rectangular hollow support. A vertical box 8 is provided at the vertical end of the lifting frame. The vertical box 8 has a hollow cavity along one side of the first transfer platform 4 in the horizontal direction. The width of the hollow cavity in the vertical box 8 is equal to the width of the first transfer platform 4. The height of the hollow cavity in the vertical box 8 is the same as the gap between the first transfer platform 4 and the second transfer platform 5. The lifting frame quickly transfers the baked product 10 in the oven and, in conjunction with the transfer platform, outputs the baked product 10 to a specific location. The lifting platform 2 transfers the baked product 10 in the oven, thereby improving the baking efficiency of the product 10, facilitating the user's automated management of the baked product 10, improving the overall baking efficiency of the device, and further improving the overall production efficiency of the product 10.

[0042] Please see Figure 1 As shown in the figure, the transfer platform 3 has a double-layer structure. The lower end of the double-layer structure is fixedly connected to a first support. The lower end of the first support is in contact with the ground, and the other end of the first support is flush with the transport window 7 of the elevator 2.

[0043] Specifically, in this embodiment, the transfer platform 3 has a double-layer structure. The lower end of the double-layer structure is fixedly connected to a first support. The lower end of the first support is in contact with the ground, and the other end of the first support is flush with the transport window 7 of the elevator 2. The first support is used to support the conveyor belt 6 structure, which facilitates the feeding device to transfer the products 10 sequentially. The products 10 can be manually transported to any horizontal transfer mechanism of the transfer platform 3 for directional transfer. There is no need for manual handling of the products 10 into the oven. The two elevators 2 quickly transfer the products 10 placed in the oven. The conveyor belts 6 of the first horizontal transfer platform 4 and the second horizontal transfer platform 5 can transfer the baked products 10 to a specific position, improving the overall baking efficiency of the device and thus further improving the overall production efficiency of the products 10.

[0044] Please see Figure 1 As shown in the figure, the upper end of the first bracket is also fixedly connected to a second bracket, which is horizontally positioned.

[0045] Specifically, in this embodiment, a second support is fixedly connected to the upper end of the first support. The second support is horizontally arranged, and a conveyor belt 6 is also provided on one side of the second support. The conveyor belt 6 can also simultaneously transfer the baked product 10. There is no need for manual handling of the product 10 to the inside of the oven. The rapid transfer of the product 10 placed in the oven by the two elevators 2, together with the first horizontal transfer platform 4 and the second horizontal transfer platform 5, can transfer the baked product 10 to a specific position by the conveyor belts 6 of the first horizontal transfer platform 4 and the second horizontal transfer platform 5, thereby improving the overall baking efficiency of the device and further improving the overall production efficiency of the product 10.

[0046] Please see Figure 1 As shown in the figure, the width of the second bracket (not shown in the figure) is smaller than the width of the first bracket (not shown in the figure), and the height of the second bracket is greater than the height of the first bracket.

[0047] Specifically, in this embodiment, the length of the second support is less than the length of the first support, and the height of the second support is greater than the height of the first support. Both the second support and the first support are equipped with a conveyor belt 6 structure. The conveyor belt 6 can also simultaneously transfer the baked product 10, eliminating the need for manual handling of the product 10 into the oven. The two elevators 2 located on both sides of the oven quickly transfer the product 10 placed inside the oven. In conjunction with the first horizontal transfer platform 4 and the second horizontal transfer platform 5, the conveyor belts 6 of the first horizontal transfer platform 4 and the second horizontal transfer platform 5 can transfer the baked product 10 to a specific position, improving the overall baking efficiency of the device, thereby further improving the overall production efficiency of the product 10.

[0048] Please see Figure 1 as well as Figure 2 As shown in the figure, the lifting frame has a transport window 7 on the side facing the double-layer structure, and the width of the transport window 7 is the same as the width of the second support and the first support.

[0049] Specifically, in this embodiment, the lifting frame is provided with a transport window 7 facing the double-layer transfer platform. The width of the transport window 7 is the same as the width of the second support, and the transport window 7 of the lifting frame is a rectangular cavity. The cavity passes through the middle of the lifting frame to form a rectangular perforation. The height of the perforation is greater than the height difference between the first support and the second support. In this arrangement, the transport window 7 is used to transport the product 10 to be baked to the corresponding lifting frame at a horizontal speed. Then, the vertical box 8 provided in the lifting frame sequentially transfers the product 10 to be baked to the corresponding... During the process, sensors inside the oven detect whether there are any empty spaces in the upper oven 11, middle oven 12, and lower oven 13. If an empty space is detected, the vertical box 8 in the lifting frame will transfer the product 10 to be baked to the corresponding empty space. The oven will then use the lifting mechanism 2 to transfer the baked product 10, thereby improving the baking efficiency of the product 10. This allows users to automatically manage the baking of the product 10, improving the overall baking efficiency of the device and further increasing the overall production efficiency of the product 10.

[0050] Please see Figure 2 as well as Figure 3 As shown in the figure, the height of the upper conveyor belt of the second transfer platform is the same as the height of the lifting frame of the elevator 2.

[0051] Specifically, in this embodiment, the height of the upper conveyor belt is the same as the height of the lifting frame set in the elevator 2. The vertical box 8 set in the elevator 2 sequentially transfers the product 10 to be baked to the corresponding empty position in the oven. During this process, the sensors set inside the oven detect whether there are corresponding empty positions in the upper oven 11, middle oven 12 and lower oven 13 inside the oven. If an empty position is detected, the vertical box 8 in the lifting frame transfers the product 10 to be baked to the corresponding empty position. The oven is then transported by the elevator 2 to transfer the baked product 10, thereby improving the baking efficiency of the product 10, facilitating the user to automatically manage the baking of the product 10, improving the overall baking efficiency of the device, and further improving the overall production efficiency of the product 10.

[0052] Please see Figure 2 as well as Figure 3 As shown in the figure, the height of the cooling conveyor belt 14 is the same as the height of the bottom end of the lifting frame of the elevator 2.

[0053] Specifically, in this embodiment, the height of the cooling conveyor belt 14 is the same as the height of the bottom of the lifting frame of the elevator 2. The cooling conveyor belt 14 of the elevator 2 is installed on the side of the lower oven 13 near the ground, and is used to horizontally transfer the baked product 10 to the side of the discharge port of the lifting frame. The baked product 10 passes through the cooling conveyor belt 14 and is transported to the corresponding transport window 7. The baked product 10 is then output from one side of the transport window 7. In this arrangement, the elevators 2 installed on both sides of the oven cooperate with each other to transfer the baked product 10 and the product 10 to be baked to a specific position in the oven, thereby improving the baking efficiency of the product 10, facilitating the user to automatically manage the baked product 10 as a whole, improving the overall baking efficiency of the device, and further improving the overall production efficiency of the product 10.

[0054] Please refer to the figure. Figure 3 As shown in the figure, the upper oven 11, the middle oven 12 and the lower oven 13 are all arranged in parallel and fixed to the inner wall of the baking oven 1 from top to bottom.

[0055] Specifically, in this embodiment, the upper oven 11, middle oven 12, and lower oven 13 are all arranged in parallel and fixed to the inner wall of the baking oven 1 from top to bottom. In one embodiment, the upper oven 11 has multiple baking placement slots arranged from left to right. The baking placement slots are arranged on the ovens of the corresponding levels. The oven has a three-layer structure, with each layer arranged in parallel. Each layer of the three-layer oven has a gap of 20cm-30cm, which facilitates the horizontal transfer of the vertical box 8 of the lifting platform 2 to the product 10 placed in the corresponding position. The three-layer oven bakes the product 10 to be baked, and the two lifting platforms 2 quickly transfer the product 10 placed in the oven. Furthermore, the conveyor belts 6 of the first and second horizontal transfer platforms can transfer the baked product 10 to a specific position, improving the overall baking efficiency of the device and thus further improving the overall production efficiency of the product 10.

[0056] Please see Figure 4 ,like Figure 4 As shown, the control method is applied to the controller of the double-layer feeding device. The controller is connected in communication with each detection sensor 9 and each elevator. The control method includes the following steps S110 to S160.

[0057] S110. Obtain the detection information of each detection sensor 9 to determine the product transfer and placement information of the transfer platform.

[0058] In this embodiment, the detection information is the transfer placement information obtained by the detection sensor 9 through directional detection of whether there are products to be baked on the conveyor belt placed in the transfer mechanism.

[0059] Specifically, if a product to be baked is detected above the current conveyor belt, the conveyor belt will be oriented in a specific direction and transported to a specific location to facilitate feeding management of products to be baked or products already baked.

[0060] S120. Determine whether each product placed inside the double-layer feeding device meets the preset discharge conditions by using a preset baking schedule; the baking schedule includes the baking record time of all products placed inside the double-layer feeding device.

[0061] In this embodiment, the baking schedule is the baking rule for baking the product to be baked, thereby determining the discharge conditions for different types of products.

[0062] Specifically, the baking time of all products in the baking schedule is recorded, that is, the feeding time and unloading time of each product placed in the baking oven for baking, so as to manage each product baking in the baking oven. In one embodiment, when the unloading time is reached, the product is taken out, which facilitates the management of the baking oven.

[0063] S130. If a product meets the discharge conditions, the baking layer of the product that meets the discharge conditions sends a first discharge instruction to the elevator located at the end away from the transfer platform.

[0064] In this embodiment, the discharge condition is the discharge time corresponding to the product.

[0065] Specifically, if the product needs to be unloaded, and the corresponding unloading time is reached, the first unloading instruction is sent to the elevator, and the product is sequentially transferred and output to another elevator, ready for the product to be transferred and output to the outside of the baking machine.

[0066] S140. Send a second discharge instruction to the elevator located near one end of the transfer platform according to the product transfer and placement information;

[0067] In this embodiment, the product transfer and placement information refers to the position of the product within the baking oven, which is then moved by the elevator to the corresponding position for transfer.

[0068] Specifically, a second discharge command is sent to another elevator to transfer the baked product to any transfer platform for horizontal transfer and output.

[0069] S150. Determine whether the product transfer and placement information meets the feeding conditions.

[0070] In this embodiment, the feeding condition is the baking time threshold, which is the time when there are extra baking positions in the baking oven and products reach the discharge time.

[0071] Specifically, if the product transfer and placement information meets the feeding conditions, the product to be baked is placed horizontally on the conveyor belt of any transfer platform by a human.

[0072] S160. If the product transfer and placement information meets the feeding conditions, send the corresponding feeding instruction to the elevator located near one end of the transfer platform according to the product transfer and placement information, and update the baking schedule according to the current time.

[0073] In this embodiment, updating the baking schedule means recording the baking time of the product and determining whether the product placed in the baking oven has reached the corresponding discharge time.

[0074] Specifically, if the product transfer information meets the feeding conditions, the lifting platform and the horizontal transfer mechanism work together to carry out the relevant operations of feeding or discharging, ensuring the continuous operation of the baking oven, improving the overall baking efficiency of the oven, and facilitating operator management.

[0075] Furthermore, in the control method of the double-layer feeding device provided in this embodiment of the invention, the control method is applied in the controller of the double-layer feeding device. The controller is used to issue commands to the baking oven and the elevator. The control method executes the following steps in sequence: First, it acquires the detection information of each detection sensor 9 to determine the product transfer and placement information of the transfer platform; second, it judges whether each product placed inside the double-layer feeding device meets the preset discharge conditions by using a preset baking time schedule; the baking time schedule includes the baking record time of all products placed inside the double-layer feeding device; third, it judges whether a certain product meets the discharge conditions, and sends a first discharge command to the elevator set at the end away from the transfer platform if the product meets the discharge conditions; fourth, it sends a second discharge command according to the product transfer and placement information. The feeding command is sent to the elevator located near one end of the transfer platform. The fifth step determines whether the product transfer and placement information meets the feeding conditions. The sixth step determines whether the product transfer and placement information meets the feeding conditions, and if so, sends the corresponding feeding command to the elevator located near the transfer platform and updates the baking schedule according to the current time. Through the above control method, the baking oven, elevator, and transfer platform cooperate with each other. The lifting frame quickly transfers the baked products in the oven, and the transfer platform outputs the baked products to a specific location. The oven uses the elevator to transfer the baked products, thereby improving the baking efficiency of the products, facilitating automated management of the baked products by the user, improving the overall baking efficiency of the device, and further improving the overall production efficiency of the products.

[0076] According to step S150 above, determining whether the product transfer and placement information meets the feeding conditions further includes performing the following sub-steps: the discharge conditions include a baking time threshold; determining whether each product placed inside the double-layer feeding device meets the preset discharge conditions using a preset baking time schedule includes:

[0077] Based on the baking time records of each product in the baking schedule, obtain the baking duration corresponding to the product with the longest baking time from the baking schedule;

[0078] Determine whether the baking time corresponding to the current product exceeds the baking time threshold, thereby determining whether the current product meets the discharge conditions.

[0079] Specifically, in this embodiment, the discharge conditions include a baking time threshold. The process involves determining whether each product placed inside the double-layer feeding device meets the preset discharge conditions using a pre-set baking time schedule. This determination includes two steps: first, based on the baking time records of each product in the baking time schedule, obtaining the baking duration corresponding to the product with the longest baking time from the baking time schedule; second, determining whether the baking duration corresponding to the current product exceeds the baking time threshold, thereby determining whether the current product meets the discharge conditions. By judging the baking time, it is determined whether the product to be baked should be lifted by the lifting mechanism on both sides. The products are transported to the corresponding transfer mechanism's conveyor belt. This setup allows for directional feeding and discharging through the transport window. The elevator simultaneously and horizontally transfers the products to be baked and the baked products to the first or second support's conveyor belt. The products are then sequentially output from one end of the transport window. This eliminates the need for manual intervention in the feeding and discharging operations, improving the overall transfer efficiency of the device and reducing production time. The elevator also transfers the baked products to the oven, further enhancing baking efficiency and facilitating automated management of the baked products, thereby further improving overall production efficiency.

[0080] Furthermore, in one embodiment, the three-layer oven, front and rear elevators, and double-layer conveyor belt mechanism for product entry and exit are all controlled by a PLC. After the product is placed, the conveyor belt start switch is pressed, and the product flows out of the conveyor belt. The front elevator, according to a signal prompt, rises to the corresponding layer to receive the product. The PLC program controls the front elevator to intelligently determine which layer of the oven the product flows into in the order of top, middle, and bottom for baking. The rear elevator, controlled by the PLC program, automatically receives the product in the order of top, middle, and bottom, and returns it through the bottom cooling zone of the three-layer oven. If one layer of the double-layer conveyor belt mechanism is empty and a signal is given when the time is up, the PLC controls the front elevator to receive the fixture for return (prioritizing feeding plates to the upper layer conveyor belt; if the upper layer signal is not met, products are fed to the lower layer). After the elevator delivers the product, it passes through the conveyor belt entry / exit sensor, and the conveyor belt operates. This process is repeated sequentially until the last product is produced and output by the double-layer conveyor belt mechanism.

[0081] This invention discloses a double-layer feeding device, comprising: a baking oven, a transfer platform, and two elevators disposed on both sides of the baking oven. The transfer platform includes a first transfer platform and a second transfer platform, both equipped with conveyor belts. Detection sensors are mounted at both ends of the drive shafts of the conveyor belts to identify whether products have entered the transport windows of the elevators. The baking oven is equipped with an oven, including an upper oven, a middle oven, and a lower oven. A cooling conveyor belt is also disposed on the side of the baking oven closest to the ground. The elevators include a lifting frame and a vertical housing slidably connected to the lifting frame. When the oven detects that the product has finished baking, the baking oven is transferred to a specific position by the elevators in conjunction with the transfer platforms, thereby improving the baking efficiency of the products in the baking oven. This eliminates the need for manual intervention in the product transfer process, improving the overall baking efficiency of the device.
