Description

Technical Field

[0001] This application relates to the field of cake production technology, and in particular to a cake demolding production line and method. Background Technology

[0002] When making mousse cake, semi-fluid ingredients are filled into a container consisting of a stainless steel ring and a base. The ingredients are then frozen to solidify. At this point, the base, ring, and cake stick together. During production, the cake needs to be removed from the base to separate the base from the ring. The base is then transported to the mold assembly station to begin a new production cycle.

[0003] In related technologies, the base of a mousse cake needs to be manually removed, and the removed base needs to be manually collected and transported to the mold assembly station. The transportation of the base is not only inefficient, but also greatly increases the labor intensity of the staff.

[0004] Therefore, how to improve the efficiency of cake tray detachment and conveying, and reduce the labor intensity of workers, is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] To help improve the efficiency of cake demolding and tray conveying, this application provides a cake demolding production line and method.

[0006] Firstly, this application provides a cake demolding production line, which adopts the following technical solution:

[0007] A cake demolding production line includes a base heating device, a cake base conveying device, a base recycling conveying line and a clamping robot. The production line is also equipped with a cake demolding station and a paper tray placement station.

[0008] The base heating device includes a first conveyor and a second conveyor for sequentially conveying frozen cakes to be removed from their bases. The first conveyor and the second conveyor are arranged to overlap at their connection points. The device also includes a heating plate arranged at the conveying position of the second conveyor for heating the cake base.

[0009] The cake base conveying device includes a third conveyor for conveying cakes to be de-based from the second conveyor, the third conveyor having a de-base station, a positioning and pressing mechanism located at the de-base station for positioning and pressing the base of the cake to be de-based, and a fourth conveyor disposed below the third conveyor for returning the base, and a transfer mechanism for transferring the base from the third conveyor to the fourth conveyor.

[0010] The clamping robot has a gripper that can clamp the cake from the bottom removal station to the cake demolding station for separating the steel ring, and then clamp the cake that has been separated from the steel ring to the paper tray at the paper tray placement station.

[0011] The bottom tray recovery conveyor line is used to receive the bottom trays conveyed by the fourth conveyor and transport the bottom trays to the next work station.

[0012] By adopting the above technical solution, the base heating device heats the base of the cake to be unmolded, causing the adhesion between the base and the cake to fail. The cake base conveying device positions and presses the cake base at the base removal station. The clamping robot clamps the cake with the steel ring from the base removal station to the cake unmolding station for steel ring separation. The cake base conveying device returns the base after it has been removed from the cake to the base recycling conveying line. The clamping robot clamps the cake that has been removed from the steel ring at the cake unmolding station and places it on the paper tray at the paper tray placement station. The entire production process is automated for base removal and base tray recycling and conveying, which improves the production efficiency of cake removal and conveying and reduces the labor intensity of workers.

[0013] Optionally, the base heating device further includes a first frame, a first conveyor mounted on the first frame, the first conveyor including a plurality of spaced first conveyor belts, a second conveyor mounted on the first frame in a liftable manner, the second conveyor including a plurality of spaced second conveyor belts, the first conveyor belts and the second conveyor belts being arranged to overlap at their joints, and a heating plate mounted on the first frame, the heating plate being arranged between the plurality of second conveyor belts. When the second conveyor is raised, the upper surfaces of the first conveyor belts and the second conveyor belts are on the same plane; when the second conveyor is lowered, the upper surface of the second conveyor belts is slightly lower than the upper surface of the heating plate or is on the same plane as the upper surface of the heating plate.

[0014] By adopting the above technical solution, the cake to be removed from the bottom is transported from the first conveyor to the second conveyor. The second conveyor descends, causing the cake to fall onto the heating plate to heat the base. The frozen cake loses its adhesion to the heated base due to the molten liquid, which helps the cake to detach from the base. This facilitates the removal of the cake from the base during the conveying process, improves the efficiency of the removal process, and reduces the labor intensity of the workers.

[0015] Optionally, the third conveyor includes a second frame, first belt rollers mounted at both ends of the second frame, a first belt and a second belt spaced on the first belt rollers for supporting and conveying the base, the upper surfaces of the first belt and the second belt forming the first conveying surface, and a second belt roller mounted on the second frame for tensioning and driving the first belt and the second belt, the second belt roller being driven by a first drive motor mounted on the second frame.

[0016] By adopting the above technical solution, the first drive motor drives the second belt roller to rotate, thereby driving the first belt and the second belt supported on the first belt roller to rotate. The first belt and the second belt transport the cake to be removed from the inlet end to the removal station, and at the same time transport the bottom tray that has been removed from the cake from the removal station to the outlet end, which helps to improve the working efficiency of the bottom tray transportation.

[0017] The positioning and clamping mechanism includes a support fixedly mounted on the second frame, a positioning cylinder mounted on the support between the first belt and the second belt, a positioning rod for positioning the bottom support fixedly mounted on the cylinder rod of the positioning cylinder, the upper end face of the positioning rod being higher than the first conveying surface when the cylinder rod extends, and the upper end face of the positioning rod being lower than the first conveying surface when the cylinder rod retracts, and a lifting cylinder mounted on the support at the bottom removal station, a support plate fixedly mounted on the cylinder rod of the lifting cylinder, the upper surface of the support plate being higher than the first conveying surface when the cylinder rod of the lifting cylinder extends, and the upper surface of the support plate being lower than the first conveying surface when the cylinder rod of the lifting cylinder retracts.

[0018] By adopting the above technical solution, when the cylinder rod of the positioning cylinder extends, the upper end face of the positioning rod extends out of the first conveying surface to position the bottom support. When the cylinder rod of the lifting cylinder extends, the support plate pushes the bottom support away from the first conveying surface, which helps to accurately position the cake at the bottom removal station. At the same time, it does not affect the third conveyor to convey cakes in other positions, thus improving the efficiency of conveying.

[0019] Optionally, the positioning and clamping mechanism further includes a clamping assembly mounted on the support for clamping the base support. The clamping assembly includes a first clamping cylinder and a second clamping cylinder arranged sequentially on both sides of the lifting cylinder along the base support conveying direction. A first transverse cylinder is provided on the cylinder rod of the first clamping cylinder, and a first pressure plate is fixedly mounted on the cylinder rod of the first transverse cylinder. A second transverse cylinder is fixedly connected to the cylinder rod of the second clamping cylinder, and a second pressure plate is fixedly mounted on the cylinder rod of the second transverse cylinder. When the cylinder rods of the first and second clamping cylinders extend, the cylinder rods of the first and second transverse cylinders extend, and the cylinder rod of the lifting cylinder extends, the first pressure plate and the second pressure plate can clamp the base support on the support plate.

[0020] By adopting the above technical solution, when the cylinder rods of the first and second pressing cylinders are extended, the first and second pressure plates are higher than the base on the support plate, the cylinder rods of the first and second transverse cylinders are extended, and the first and second pressure plates are placed above the two side edges of the base, when the cylinder rods of the first and second pressing cylinders are extended, and the cylinder rod of the lifting cylinder is extended, the first and second pressure plates press the base onto the support plate, which helps to improve the reliability of the cake separating from the base when the cake is detached from the base.

[0021] Optionally, the transfer mechanism includes a bracket fixedly mounted on the second frame, a flipping assembly for flipping the bottom support on the first conveying surface from a horizontal state to a vertical state, and a lifting assembly for moving the vertically positioned bottom support from the third conveyor to the fourth conveyor; the lifting assembly includes a guide rod cylinder, the guide rod of which is vertically fixedly mounted on the bracket, and the cylinder barrel of which can slide on the guide rod between the third and fourth conveyors; the flipping assembly includes a rotary cylinder fixedly mounted on the cylinder barrel. A flap is fixedly installed on the rotating rod of the cylinder, and a fixed plate is fixedly installed on the cylinder body of the rotating cylinder. The fixed plate is provided with an elastic element. When the rotating cylinder is located at the third conveyor position and the rotating rod of the rotating cylinder is at the initial rotation position, the upper surface of the flap is lower than the first conveying surface. When the rotating rod of the rotating cylinder is in the rotation position, the rotating base of the flap is vertically pressed against the elastic element of the fixed plate. When the flap is located at the fourth conveyor position and the rotating rod of the rotating cylinder returns to the initial rotation position, the upper surface of the flap is lower than the second conveying surface of the fourth conveyor.

[0022] By adopting the above technical solution, the transfer mechanism flips the base tray to a vertical position through the flipping component, which helps to avoid interference with the third transfer mechanism when the base tray moves down to the second transfer surface. At the same time, when the lifting component moves the vertical base tray from the first transfer surface to the second transfer surface, it helps to reduce the space occupied by the base tray transfer. The flipping plate presses the base tray against the elastic element of the fixed plate, which helps to tilt the base tray and automatically fall to the second transfer surface through the rebound of the elastic element, thereby improving the efficiency of base tray transfer.

[0023] Optionally, the fourth conveyor includes a third frame, a third belt and a fourth belt rotatably mounted on the third frame at intervals, the upper surfaces of the third belt and the fourth belt forming the second conveying surface, and further includes a pushing assembly and a lifting assembly mounted at the end away from the transfer mechanism. The pushing assembly includes a mounting base, a pushing cylinder, a guide column, a guide seat, and a pushing block. The mounting base is mounted on the third frame, the guide seat is mounted on the mounting base, the guide column slides on the guide seat, the pushing block is fixed to one end of the guide column, and the piston rod of the pushing cylinder is fixed to the pushing block. The lifting assembly is installed between the third belt and the fourth belt. The lifting assembly includes a lifting cylinder, which is fixed to the third frame. A lifting plate is fixedly mounted on the piston rod of the lifting cylinder. When the piston rod of the lifting cylinder extends, the lifting plate pushes the bottom support away from the second conveying surface. When the piston rod of the pushing cylinder extends, it drives the pushing block to push the bottom support onto the bottom support recycling conveyor line.

[0024] By adopting the above technical solution, the second drive motor drives the fourth belt roller to rotate, thereby driving the third belt and the fourth belt supported on the third belt roller to rotate. The third belt and the fourth belt transport the bottom tray back. The pushing component and the lifting component installed at the end away from the transfer mechanism lift the bottom tray by lifting the bottom tray so that the bottom tray is separated from the second conveying surface by lifting the bottom tray. The pushing component pushes the bottom tray to the bottom tray recycling conveyor line for recycling and transportation. This helps to prevent the bottom tray from damaging the third belt and the fourth belt, and also improves the working efficiency of the bottom tray return transportation.

[0025] Optionally, the production line further includes a steel ring separation device, which has two cake demolding stations, correspondingly equipped with a first half-mold heating mechanism and a second half-mold heating mechanism. A first ejection mechanism is provided below the first half-mold heating mechanism, and a second ejection mechanism is provided below the second half-mold heating mechanism. A first ejection mechanism and a second ejection mechanism are provided between the first half-mold heating mechanism and the second half-mold heating mechanism. A first steel ring recycling conveying device is installed on the side of the first half-mold heating mechanism away from the first ejection mechanism, and a second steel ring recycling conveying device is installed on the side of the second half-mold heating mechanism away from the second ejection mechanism. The first ejection mechanism pushes the demolded steel ring into the first steel ring recycling conveying device, and the second ejection mechanism pushes the demolded steel ring into the second steel ring recycling conveying device.

[0026] By adopting the above technical solution, the steel ring separation device has two cake demolding stations, which helps to improve the efficiency of cake demolding. When the first half-mold heating mechanism and the second half-mold heating mechanism are in the mold closing heating state, they can heat the two cakes. The first ejection mechanism and the second ejection mechanism eject the cakes in the steel rings heated by the first half-mold heating mechanism and the second half-mold heating mechanism, respectively. The first push-out mechanism and the second push-out mechanism push the steel rings into the first steel ring recycling conveyor and the second steel ring recycling conveyor, respectively, which improves the efficiency of cake demolding and steel ring recycling.

[0027] Optionally, the clamping robot includes a robot body and a gripper installed at the end of the robot body. The robot body is installed above the bottom removal station and the cake demolding station. The gripper includes two pairs of clamping cylinders fixedly installed on the robot body. A clamping part is fixedly installed on the piston rod of the clamping cylinder. The lower end of the clamping part is provided with a support part for supporting the bottom of the cake. Driven by the robot body, the gripper moves the cake clamp with steel ring at the bottom removal station to the two cake demolding stations and transports the demolded cake clamp to the paper tray placement position.

[0028] By adopting the above technical solution, the clamping robot uses the gripping cylinder of the gripper to drive the clamping part to clamp the cake at the bottom removal station, and uses the support part to support the bottom of the cake. The movement of the robot body moves the cake to the cake demolding station. After being demolded at the cake demolding station, the cake is also clamped and transported to the paper tray placement station by the clamping action of the clamping robot. This helps to improve the reliability of clamping the cake, and at the same time, improves the efficiency of transferring the cake between the various stations.

[0029] Secondly, this application provides a cake demolding method, applied to the aforementioned cake demolding production line, comprising the following steps:

[0030] S200: Convey the cake to be unmolded, and heat the cake base during the conveying process;

[0031] S210. The heated cake on the base tray is conveyed to the bottom removal station and positioned. The cake is lifted off the first conveying surface and pressed against the base tray.

[0032] S220. Place the cake with the steel ring from the bottom removal station to the cake demolding station and heat the steel ring.

[0033] S230: Reset the cake tray that has detached from the cake onto the first conveyor surface and continue conveying it; transfer the cake tray on the first conveyor surface to the second conveyor surface and convey it; lift the cake tray on the second conveyor surface and push it into the cake tray recycling conveyor line.

[0034] S240. Push the cake out of the steel ring, transport the ejected cake clamp to the paper tray placement station, and transport the cake and paper tray together to the next station.

[0035] S250: Push the steel ring that has detached from the cake into the steel ring recycling conveyor for recycling and conveying;

[0036] S260. The base tray and the steel ring of the steel ring recycling conveyor on the base tray recycling conveyor line are both transported to the mold recycling return conveyor line for return transport.

[0037] Steps S220 and S230 are performed simultaneously.

[0038] By adopting the above technical solution, the cake to be demolded heats the base during conveying. The heated cake is positioned at the bottom removal station, where the base is lifted and pressed. The cake is then transported from the bottom removal station to the demolding station, where the steel ring is heated. The cake base detached from the cake is transferred from the first conveying surface to the second conveying surface, where the base is lifted and pushed into the recycling conveying device. The heated cake is pushed out of the steel ring and transported to the paper tray placement position. The steel ring is pushed into the steel ring recycling conveying device for recycling. Finally, the base on the base recycling conveying line and the steel ring on the steel ring recycling conveying device are both transported to the mold recycling return conveying line for return transport. The transfer and conveying of the cake base after bottom removal, along with the transport of the cake to the demolding station for demolding and the conveying of the steel ring detached from the cake, are carried out simultaneously and are returned to the mold recycling return conveying line. This helps to improve the efficiency of removing the base, removing the steel ring, and transporting the base and steel ring.

[0039] In summary, this application includes at least one of the following beneficial technical effects:

[0040] 1. The base heating device heats the base of the cake to be unmolded. The frozen cake loses its adhesion to the base due to the heat. The cake is then removed from the base on the cake base conveyor. The cake is then returned to the base recycling conveyor line. The clamping robot clamps the cake with the steel ring from the base removal station to the cake unmolding station. At the cake unmolding station, the clamping robot clamps the cake that has detached from the steel ring onto the paper tray of the cake conveyor. The entire production process is automated, which improves the production efficiency of cake removal and conveying and reduces the labor intensity of workers.

[0041] 2. The cake to be removed from the bottom is conveyed from the first conveyor to the second conveyor. The second conveyor descends, causing the cake to fall onto the heating plate to heat the base. The frozen cake loses its adhesion to the heated base due to the molten liquid, which helps the cake to detach from the base. This facilitates the removal of the cake from the base during the conveying process, improving the efficiency of the removal process and reducing the labor intensity of the workers.

[0042] 3. The first drive motor drives the second belt roller to rotate, thereby driving the first belt and the second belt supported on the first belt roller to rotate. The first belt and the second belt transport the cake to be removed from the inlet end to the removal station, and at the same time transport the bottom tray that has been removed from the cake from the removal station to the outlet end, which helps to improve the working efficiency of the bottom tray transportation.

[0043] 4. When the cylinder rod of the positioning cylinder extends, the upper end of the positioning rod extends out of the first conveying surface to position the bottom support. When the cylinder rod of the lifting cylinder extends, the support plate pushes the bottom support away from the first conveying surface, which helps to accurately position the cake at the bottom removal station. At the same time, it does not affect the first conveying mechanism to convey cakes in other positions, thus improving the conveying efficiency.

[0044] 5. When the cylinder rods of the first and second pressing cylinders are extended, the first and second pressure plates are higher than the base on the support plate. When the cylinder rods of the first and second transverse cylinders are extended, the first and second pressure plates are placed above the two side edges of the base. When the cylinder rods of the first and second pressing cylinders are extended, and the cylinder rod of the lifting cylinder is extended, the first and second pressure plates press the base onto the support plate. When the cake is detached from the base, this helps to improve the reliability of the cake detaching from the base.

[0045] 6. The transfer mechanism flips the base tray to a vertical position through the flipping component, which helps to avoid interference with the third conveyor when the base tray moves down to the second conveying surface. At the same time, when the lifting component moves the vertical base tray from the first conveying surface to the second conveying surface, it helps the base tray to fall automatically on the second conveying surface, which helps to reduce the space occupied by the base tray transfer and improve the efficiency of the base tray transfer.

[0046] 7. The third and fourth belts are used for the return transport of the base tray. The pushing and lifting components installed at the end away from the transfer mechanism lift the base tray by lifting it off the second conveying surface, and push it by pushing it to the base tray recycling conveyor line for recycling. This helps to prevent the base tray from damaging the third and fourth belts, and also improves the efficiency of the base tray return transport.

[0047] 8. The steel ring separation device has two cake demolding stations, which helps to improve the efficiency of cake demolding. When the first half-mold heating mechanism and the second half-mold heating mechanism are in the mold closing heating, they can heat the two cakes. The first ejection mechanism and the second ejection mechanism eject the cakes in the steel rings heated by the first half-mold heating mechanism and the second half-mold heating mechanism, respectively. The first push-out mechanism and the second push-out mechanism push the steel rings into the first steel ring recycling conveyor and the second steel ring recycling conveyor, respectively, which improves the efficiency of cake demolding and steel ring recycling.

[0048] 9. The clamping robot uses the gripping cylinder of the gripper to drive the clamping part to clamp the cake at the bottom removal station, and uses the support part to support the bottom of the cake. The robot moves the cake to the demolding station through the movement of the robot body. After the cake is demolded at the demolding station, it is also clamped and transported to the paper tray placement position by the clamping action of the clamping robot. This helps to improve the reliability of clamping the cake and at the same time, improves the efficiency of transferring the cake between the stations.

[0049] 10. The transfer and conveying of the cake base after it has been removed from the mold is carried out simultaneously with the cake clamps to be unmolded at the demolding station and the conveying of the cake's steel ring. The cake is also conveyed back to the mold recycling and return conveyor line, which helps to improve the efficiency of removing the base, removing the steel ring, and recycling and conveying the base and steel ring.

[0067] The following combination Figures 1 to 14 This application will be described in further detail.

[0068] This application discloses a cake demolding production line. (Refer to...) Figure 1 and Figure 2 The production line includes a base heating device 1, a cake base conveying device 2, a base recycling conveying line 5, and a clamping robot 3. The production line is also equipped with a cake demolding station 104 and a paper tray placement station 105.

[0069] The base heating device 1 includes a first conveyor 11 and a second conveyor 12. The first conveyor 11 and the second conveyor 12 convey the cake to be demolded in sequence. The first conveyor 11 and the second conveyor 12 are arranged to overlap at the connection point. A heating plate 13 is arranged at the position through which the second conveyor 12 conveys the cake. The second conveyor 12 heats the base while conveying the cake.

[0070] The cake base conveying device 2 includes a third conveyor 21, a fourth conveyor 24, and a transfer mechanism 23. The second conveyor 12 conveys the heated cake base to the third conveyor 21. The third conveyor 21 is equipped with a bottom removal station 103, and a positioning and pressing mechanism 22 is provided on the bottom removal station 103 to position and press the cake base to be demolded. The clamping robot 3 clamps the cake with steel ring off the base. The fourth conveyor 24 is arranged below the third conveyor 21. The transfer mechanism 23 transfers the base on the third conveyor 21 to the fourth conveyor 24. The fourth conveyor 24 returns the base.

[0071] The clamping robot 3 has a gripper 32, which can transport the cake clamp with steel ring from the bottom removal station 103 to the cake demolding station 104 to separate the steel ring. At the cake demolding station 104, the cake clamp that has been separated from the steel ring is transported to the paper tray at the paper tray placement station 105.

[0072] The bottom tray recovery conveyor line 5 is used to receive the bottom trays conveyed by the fourth conveyor 24 and transport the bottom trays to the next work station;

[0073] The production line also includes a steel ring separation device 4, which has a cake demolding station 104. The cake demolding station 104 is equipped with a heating mechanism, an ejection mechanism and a pushing mechanism. The heating mechanism heats the cake with the steel ring, the ejection mechanism ejects the heated cake out of the steel ring, and the pushing mechanism pushes the demolded steel ring into the steel ring recycling conveyor for recycling and conveying.

[0074] The production line also includes a cake conveyor 7, which is equipped with a paper tray placement station 105. The cake conveyor 7 can transport the cake and paper tray placed on the paper tray to the next station.

[0075] The production line also includes a steel ring recycling conveyor, which receives the steel rings pushed in by the ejection mechanism and conveys the steel rings to the mold recycling return conveyor line 6.

[0076] The production line also includes a mold recycling and return conveyor line 6, which receives the base trays conveyed from the base tray recycling conveyor line 5 and the steel rings conveyed from the steel ring recycling conveyor, and transports the base trays and steel rings to the next station.

[0077] The base heating device 1 heats the base of the cake to be unmolded. The adhesion between the base and the cake caused by freezing is weakened by the heating. The cake base conveying device 2 positions and presses the cake base at the unmolding station 103. The cake base conveying device 2 then returns the unmolded base to the base recycling conveyor line 5. The clamping robot 3 clamps the cake with the steel ring from the unmolding station 103 to the cake unmolding station 104 to remove the steel ring. The heating mechanism heats the steel ring, reducing the adhesion between the steel ring and the cake. If the ejection mechanism fails, it lifts the cake out of the steel ring. The clamping robot 3 then clamps the cake onto the paper tray of the cake conveyor. The ejection mechanism resets, and the push-out mechanism pushes the steel ring into the steel ring recycling conveyor. The base tray recycling conveyor 5 then transports the base tray and steel ring to the mold recycling return conveyor 6. The entire production process is automated, removing the base tray and steel ring, and converging the base tray and steel ring into the mold recycling return conveyor 6 for the next step of transport. This improves the production efficiency of cake demolding and reduces the labor intensity of workers.

[0078] Reference Figure 3The base heating device 1 also includes a first frame 14, on which a first conveyor 11 is mounted. The first conveyor 11 includes several spaced-apart first conveyor belts 111. In this embodiment, there are three first conveyor belts 111; in other embodiments, there are two or four. A second conveyor 12 is vertically mounted on the first frame 14. The second conveyor 12 is lifted and lowered on the first frame 14 by a lifting cylinder. The second conveyor 12 includes several spaced-apart second conveyor belts 121. In this embodiment, there are four second conveyor belts 121; in other embodiments, there are three or five. The first conveyor belts 111 and the second conveyor belts 121 are arranged in a cross-over pattern at their connection points. The device also includes a device installed on... The heating plate 13 on the first frame 14 is arranged between several second conveyor belts 121. When the second conveyor 12 is raised, the upper plane of the first conveyor belt 111 and the upper plane of the second conveyor belt 121 are on the same plane. When the second conveyor 12 is lowered, the upper plane of the second conveyor belt 121 is slightly lower than the upper plane of the heating plate 13 or on the same plane as the upper plane of the heating plate 13. The cake to be removed from the bottom is conveyed from the first conveyor 11 to the second conveyor 12. The second conveyor 12 is lowered so that the cake to be removed from the bottom falls onto the heating plate 13 to heat the bottom tray. The frozen cake and the heated bottom tray lose their adhesive force due to the molten liquid, which helps the cake to be removed from the bottom tray, improves the efficiency of removing the bottom tray, and reduces the labor intensity of the workers.

[0079] Reference Figures 4 to 6 The third conveyor 21 includes a second frame 211, first belt rollers 212 installed at both ends of the second frame 211, and first belts 213 and 214 installed at intervals on the first belt rollers 212 for supporting and conveying the bottom trays. The upper surfaces of the first belts 213 and 214 form a first conveying surface 101. A second belt roller 215 is installed on the second frame 211 for tensioning and driving the first belts 213 and 214. The second belt roller 215 is driven by a first drive motor 216 installed on the second frame 211. The first drive motor 216 drives the second belt roller 215 to rotate, thereby driving the first belts 213 and 214 supported on the first belt rollers 212 to rotate. The first belts 213 and 214 convey the cake to be removed from the inlet end to the removal station 103, and at the same time convey the bottom trays removed from the cakes from the removal station 103 to the outlet end, which helps to improve the working efficiency of the bottom tray conveying.

[0080] Reference Figure 7The positioning and clamping mechanism 22 includes a support 221 fixedly mounted on the second frame 211. A positioning cylinder 222 is mounted on the support 221 between the first belt 213 and the second belt 214. A positioning rod 223 for positioning the bottom support is fixedly mounted on the cylinder rod of the positioning cylinder 222. When the cylinder rod extends, the upper end face of the positioning rod 223 is higher than the first conveying surface 101. When the cylinder rod retracts, the upper end face of the positioning rod 223 is lower than the first conveying surface 101. The mechanism also includes a lifting cylinder 224 mounted on the support 221 at the bottom removal station 103. A support plate 225 is fixedly mounted on the cylinder rod of the lifting cylinder 224. When the cylinder rod of the lifting cylinder 224 extends, the upper surface of the support plate 225 is higher than the first conveying surface 101. When the cylinder rod of the lifting cylinder 224 retracts, the upper surface of the support plate 225 is lower than the first conveying surface 101. When the cylinder rod of the positioning cylinder 222 extends, the upper end of the positioning rod 223 extends out of the first conveying surface 101 to position the bottom support. When the cylinder rod of the lifting cylinder 224 extends, the support plate 225 pushes the bottom support away from the first conveying surface 101, which helps to accurately position the cake at the bottom removal station 103. At the same time, it does not affect the third conveyor 21 to convey cakes in other positions, thus improving the efficiency of conveying.

[0081] Reference Figure 7 The positioning and clamping mechanism 22 also includes a clamping assembly 226 mounted on the support 221 for clamping the base support. The clamping assembly 226 includes a first clamping cylinder 2261 and a second clamping cylinder 2262 arranged sequentially on both sides of the lifting cylinder 224 along the conveying direction of the base support. A first transverse cylinder 2263 is provided on the cylinder rod of the first clamping cylinder 2261, and a first pressure plate 2265 is fixedly installed on the cylinder rod of the first transverse cylinder 2263. A second transverse cylinder 2264 is fixedly connected to the cylinder rod of the second clamping cylinder 2262, and a second pressure plate 2266 is fixedly installed on the cylinder rod of the second transverse cylinder 2264. When the cylinder rods of the first clamping cylinder 2261 and the second clamping cylinder 2262 extend, the cylinder rods of the first transverse cylinder 2263 and the second transverse cylinder 2264 extend, lifting... When the cylinder rod of cylinder 224 extends, the first pressure plate 2265 and the second pressure plate 2266 can press the base on the support plate 225. When the cylinder rods of the first pressing cylinder 2261 and the second pressing cylinder 2262 extend, the first pressure plate 2265 and the second pressure plate 2266 are higher than the base located on the support plate 225. When the cylinder rods of the first transverse cylinder 2263 and the second transverse cylinder 2264 extend, the first pressure plate 2265 and the second pressure plate 2266 are positioned above the two side edges of the base. When the cylinder rods of the first pressing cylinder 2261 and the second pressing cylinder 2262 extend, and the cylinder rod of the lifting cylinder 224 extends, the first pressure plate 2265 and the second pressure plate 2266 press the base on the support plate 225. When the cake detaches from the base, this helps to improve the reliability of the cake detaching from the base.

[0082] Reference Figure 8 and Figure 9 The transfer mechanism 23 includes a bracket 231 fixedly mounted on the second frame 211. A flipping assembly 233 is mounted on the bracket 231 to flip the bottom support on the first conveying surface 101 from a horizontal state to a vertical state, and a lifting assembly 232 is mounted to move the vertically positioned bottom support from the third conveyor 21 to the fourth conveyor 24. The lifting assembly 232 includes a guide rod cylinder 2321, with the guide rod 23211 vertically fixedly mounted on the bracket 231. The cylinder 23212 can slide on the guide rod 23211 between the third conveyor 21 and the fourth conveyor 24. The flipping assembly 233 includes a rotary cylinder 2331 fixedly mounted on the cylinder cylinder 23212. A flip plate 2332 is fixedly mounted on the rotating rod of the rotary cylinder 2331. A fixing plate 2333 is fixedly mounted on the cylinder body of the rotary cylinder 2331. An elastic element 23331 is provided on the fixing plate 2333. In this application, the elastic element 23331 is elastic rubber. In other embodiments of this application, it is a spring. When the rotary cylinder 2331 is located at the third conveyor 21, and the rotating rod of the rotary cylinder 2331 is at the initial rotation position, the upper surface of the flap 2332 is lower than the first conveying surface 101. When the rotating rod of the rotary cylinder 2331 is in the rotation position, the rotating base of the flap 2332 is vertically pressed against the fixed plate 2333. When the flap 2332 is located at the fourth conveyor 24, and the rotating rod of the rotary cylinder 2331 returns to the initial rotation position, the upper surface of the flap 2332 is lower than the first conveying surface 101 of the fourth conveyor 24. The transfer mechanism 23 flips the base tray to a vertical position via the flipping component 233 on the second conveyor surface 102, which helps to avoid interference with the third conveyor 21 when the base tray moves down to the second conveyor surface 102. At the same time, when the lifting component 232 moves the vertical base tray from the first conveyor surface 101 to the second conveyor surface 102, the elastic element 23331 causes the base tray to tilt and automatically fall onto the second conveyor surface 102, which helps to reduce the space occupied by the base tray transfer and improve the efficiency of the base tray transfer.

[0083] Reference Figure 4 , Figure 10 and Figure 11The fourth conveyor 24 includes a third frame 241, a third belt 243 and a fourth belt 244 rotatably mounted on the third frame 241 and spaced apart, the upper surfaces of the third belt 243 and the fourth belt 244 forming a second conveying surface 102. It also includes a pushing assembly 26 and a lifting assembly 27 mounted at the end away from the transfer mechanism 23. The pushing assembly 26 includes a mounting base 261, a pushing cylinder 262, a guide post 263, a guide seat 264, and a push block 265. The mounting base 261 is mounted on the third frame 241, the guide seat 264 is mounted on the mounting base 261, the guide post 263 slides on the guide seat 264, the push block 265 is fixed to one end of the guide post 263, and the piston rod of the pushing cylinder 262 is fixed to the push block 265. The lifting assembly 27 is installed between the third belt 243 and the fourth belt 244. The lifting assembly 27 includes a lifting cylinder 271, which is fixed to the third frame 241 and lifts... A lifting plate 272 is fixedly installed on the piston rod of cylinder 271. When the piston rod of lifting cylinder 271 extends, lifting plate 272 pushes the bottom support away from the second conveying surface 102. When the piston rod of pushing cylinder 262 extends, it drives push block 265 to push the bottom support onto bottom support recycling conveyor line 5. Second drive motor 246 drives the fourth belt 244 to rotate, thereby driving the third belt 243 and fourth belt 244 supported on the third belt roller 242 to rotate. The third belt 243 and fourth belt 244 perform return conveying of the bottom support. Pushing component 26 and lifting component 27 are installed at the end away from transfer mechanism 23. Lifting component 27 lifts the bottom support to make it detach from the second conveying surface 102. Pushing component 26 pushes the bottom support onto bottom support recycling conveyor line 5 for recycling conveying. This helps prevent the bottom support from damaging the third belt 243 and fourth belt 244, and also improves the working efficiency of bottom support return conveying.

Driven by the robot body 31, the gripper 32 moves at the bottom removal station. 103 The cake clamp with steel ring is moved to the two cake demolding stations 104. The demolded cake clamp is transported to the paper tray placement position. The clamping robot 3 drives the clamping part 322 to clamp the cake at the bottom removal station 103 through the clamping cylinder 321 of the gripper 32, and the bottom of the cake is supported by the support part 3221. The cake is moved to the demolding station by the movement of the robot body 31. The cake after demolding at the cake demolding station 104 is also transported to the paper tray placement station 105 by the clamping action of the clamping robot 3. This helps to improve the reliability of clamping the cake and improves the efficiency of transferring the cake between the stations.

[0086] This application also discloses a cake demolding method, applied to the aforementioned cake demolding production line, with reference to... Figure 14 It includes the following steps:

[0087] S200: Convey the cake to be unmolded, and heat the cake base during the conveying process;

[0088] S210. The cake after heating the base is conveyed to the bottom removal station 103 and positioned. The cake is lifted off the first conveying surface 101 and the base is pressed firmly.

[0089] S220. Place the cake with the steel ring from the bottom removal station 103 to the cake demolding station 104, close the half mold and heat the steel ring;

[0090] S230: Reset the cake tray on the first conveying surface 101 and continue conveying. Transfer the tray on the first conveying surface 101 to the second conveying surface 102 and convey it. Lift the tray on the second conveying surface 102 and push it into the tray recycling conveying line 5 for recycling.

[0091] S240, the ejection mechanism ejects the cake from the steel ring at the demolding station, and transports the ejected cake clamp to the paper tray placement position, and conveys the cake and paper tray together to the next station;

[0092] S250: Open the heated half mold, reset the ejection mechanism, and push the steel ring into the steel ring recycling conveyor for recycling and conveying.

[0093] S260. The base tray and the steel ring of the steel ring recycling conveyor on the base tray recycling conveyor line 5 are both transported to the mold recycling return conveyor line 6 for return transport.

[0094] Steps S220 and S230 are performed simultaneously.

[0095] The cake to be demolded is heated on its base during transport. After heating, the cake is positioned at the bottom-removal station 103, where the base is lifted and pressed. The cake at the bottom-removal station 103 is then transported to the demolding station, where the steel ring is heated. The cake base, detached from the cake, is transferred from the first conveyor surface 101 to the second conveyor surface 102. The base on the second conveyor surface 102 is lifted and pushed into the base recovery conveyor line 5, pushing the heated cake out of the steel ring and transporting it to the paper tray placement position. The steel ring is then pushed into the steel tray. The ring recycling conveyor device recycles and conveys the cake. Finally, the bottom tray on the bottom tray recycling conveyor line 5 and the steel ring on the steel ring recycling conveyor device are transported to the mold recycling return conveyor line 6 for return conveying. The bottom tray after the cake is removed is transferred and conveyed, and the cake to be demolded is transported to the cake demolding station 104 for demolding. The steel ring that is removed from the cake is conveyed at the same time and returned to the mold recycling return conveyor line 6. This helps to improve the efficiency of removing the bottom tray, removing the steel ring, and conveying the bottom tray and steel ring.
