[0029] To make the technical means, technical features, utility model purpose and technical effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0030] like Figures 1-10 As shown, a fully automatic tray-stacking machine with tray-dropping and tray-separating functions includes an upper frame 1, a lower frame 2, a tray-dropping and tray-separating assembly, a tray-pushing mechanism, a steamed bun conveying mechanism, a tray-stacking mechanism, and an electrical control system 43. The upper frame 1 is detachably connected to the lower frame 2 by bolts. The tray-dropping and tray-separating assembly, the tray-pushing mechanism, and the steamed bun conveying mechanism are all installed on the lower frame 2. The tray-dropping and tray-separating assembly is located on one side of the upper frame 1 and is used for stacking multiple steaming trays, enabling the trays to be dropped and conveyed one by one. The tray-pushing mechanism separates trays along the length of the lower frame 2. The cloth extends from the tray-distribution assembly towards the upper frame 1, and is used to sequentially transport the steaming trays from the tray-distribution assembly to the tray-setting mechanism. The steamed bun conveying mechanism is distributed along the width of the lower frame 2 and is used to transport the steamed buns. The tray-setting mechanism is installed on the upper frame 1 and is used to grab the steamed buns transported by the steamed bun conveying mechanism and place them in the steaming trays. The electrical control system 43 is installed on the top of the upper frame 1. The tray-distribution assembly, the tray-pushing mechanism, the steamed bun conveying mechanism, and the tray-setting mechanism are all electrically connected to the electrical control system 43 to realize intelligent control.

[0031] like Figures 1-4 As shown, the tray-dispensing assembly includes a lifting and receiving mechanism, a side positioning mechanism, and a storage mechanism. The lifting and receiving mechanism is installed below the two platforms of the lower frame, the storage mechanism is installed above the two platforms of the lower frame, and the lifting and receiving mechanism is located below the storage mechanism. There are two side positioning mechanisms, which are symmetrically distributed on both sides of the storage mechanism.

[0032] The storage mechanism includes four empty tray limiting brackets 3, which are symmetrically distributed in pairs, so that the four empty tray limiting brackets 3 form a chamber for placing steaming trays. Multiple stacked steaming trays are placed in the chamber in sequence. Two tray supports 4 are installed on the lower frame 2 and below the chamber. The two tray supports 4 are symmetrically distributed.

[0033] The lifting and receiving mechanism includes a vertical cylinder 6, a vertical linear guide rail 7, and a support plate 8. The fixed end of the vertical cylinder 6 is connected to the lower frame 2. There are two vertical linear guide rails 7, which are symmetrically distributed and installed on the lower frame 2. The support plate 8 is connected to the extended end of the vertical cylinder 6. The slide rail of the vertical linear guide rail 7 is connected to the support plate 8 through a fixed bracket 9.

[0034] The side positioning mechanism includes a side cylinder 10, a side linear guide rail 11, and a slide plate 12. The side cylinder 10 and the side linear guide rail 11 are both mounted on the lower frame 2. The slide plate 12 is connected to the extended end of the side cylinder 10 and to the slider of the side linear guide rail 11.

[0035] After multiple steaming trays are stacked, they are placed in the cavity formed by the empty tray limiting bracket 3. The side cylinder 10 extends, and the insert plate 12 moves along the side linear guide rail 11 to support and position the two sides of the bottom first steaming tray. When the steaming tray needs to be transported, the vertical cylinder 6 extends, driving the support plate 8 to move and rise along the vertical linear guide rail 7. The support plate 8 supports the bottom first steaming tray, the side cylinder 10 retracts, and the vertical cylinder 6 retracts by the distance of one steaming tray. Then the side cylinder 10 extends again, so that the insert plate 12 supports the second and more steaming trays. The vertical cylinder 6 retracts completely, and the bottom first steaming tray is placed and supported on the tray bracket 4, completing the separation of one steaming tray.

[0036] like Figure 5 and Figure 6As shown, the tray feeding mechanism includes a tray feeding motor 13, a tray feeding drive shaft 14, a tray feeding driven shaft 15, and a tray feeding proximity switch 16. The tray feeding motor 13 is installed below the lower frame 2. The tray feeding drive shaft 14 and the tray feeding driven shaft 15 are rotatably mounted on the lower frame 2. The tray feeding motor 13 is connected to the tray feeding drive shaft 14 via a drive chain. A tray feeding motor sprocket 17 is installed on the output shaft of the tray feeding motor 13, and a tray feeding drive sprocket 18 is installed on the tray feeding drive shaft 14. The tray feeding motor sprocket 17 and the tray feeding drive sprocket 18 are connected by a tray feeding drive chain. Two tray feeding drive sprockets 16 are installed on the tray feeding drive shaft 14. 9. Two tray-feeding driven sprockets 20 are installed on the tray-feeding driven shaft 15. Two tray-feeding chains 21 connect two tray-feeding driving sprockets 19 and two tray-feeding driven sprockets 20. Four tray-pushing claws 22 are evenly distributed on the tray-feeding chains 21. The tray-pushing claws 22 on the two tray-feeding chains 21 are distributed one-to-one. The tray-feeding driving shaft 14 is driven to rotate by the tray-feeding motor 13, so that the tray-feeding chains 21 reciprocate between the tray-feeding driving sprockets 19 and the tray-feeding driven sprockets 20. During the rotation, the tray-pushing claws 22 push the steaming trays on the tray support 4 in sequence. The tray-feeding proximity switch 16 is installed below the table surface of the lower frame 2 and on the side close to the tray-feeding driving shaft 14. It is used to sense whether the tray-pushing claws 22 are in place when the equipment is started.

[0037] like Figure 7 and Figure 8 As shown, the steamed bun conveying mechanism includes a conveyor motor 23, a drive roller 24, a support plate 25, and a conveyor belt 26. The conveyor motor 23 is mounted on the lower frame 2, and the drive roller 24 is rotatably mounted below the platform of the lower frame 2. The conveyor motor 23 and the drive roller 24 are connected by a drive. In this embodiment, the conveyor motor 23 and the drive roller 24 are driven by a synchronous belt. Synchronous pulleys are mounted on the output shaft of the conveyor motor 23 and the drive roller 24. The two synchronous pulleys are connected by a synchronous belt. The support plate 25 is connected to the lower frame 2 through a conveyor bracket 27. Pulling rollers 28 are mounted at both ends of the support plate 25. The pulling rollers 28 can rotate relative to the support plate 25. The conveyor belt 26 is wound between the two pulling rollers 28 and the drive roller 24. The conveyor motor 23 drives the drive roller 24 to rotate, thereby realizing the conveyor belt 26 conveying the steamed buns.

[0038] To maintain the tension of the conveyor belt 26 during use, a tensioning roller 29 is installed between two conveyor supports 27 on the side near the drive roller 24. There are two tensioning rollers 29, which are distributed on both sides of the drive roller 24. The conveyor belt 26 passes around the tensioning rollers 29 to achieve the purpose of tensioning.

[0039] A sensor switch 30 is installed on the support plate 25. The sensor switch 30 is divided into a round steamed bun sensor switch 30 and a square steamed bun sensor switch 30, which are used to sense round steamed buns and square steamed buns respectively. The round steamed bun sensor switch 30 is installed at both ends of the support plate 25 to sense the round steamed bun in place. The square steamed bun sensor switch 30 is installed in the middle of the support plate 25, slightly off to one side, to sense the square steamed bun in place. When in use, whether the round steamed bun or the square steamed bun is input from the left or right, it can be automatically switched by simply switching the command through the electrical control system 43.

[0040] like Figure 9 and Figure 10 As shown, the swivel mechanism includes a grid plate 31, a swivel motor 32, a swing arm 33, a push rod 34, a fixed connecting plate 35, a longitudinal linear guide rail 36, a transverse linear guide rail 37, a fixed plate 38, and a finger cylinder 39. The grid plate 31 is mounted on the upper frame 1. The swivel motor 32 and the transverse linear guide rail 37 are both mounted on the grid plate 31. The swing arm 33 is connected to the output shaft of the swivel motor 32. A long groove is machined on the swing arm 33, and a J-shaped groove is machined on the grid plate 31. The push rod 34 passes through the J-shaped groove and the long groove in sequence and is then connected to the fixed connecting plate 35. Rolling bearings are installed at the positions where the push rod 34 passes through the J-shaped groove and the long groove to improve the smooth rotation of the push rod 34. The slide rail of the longitudinal linear guide rail 36 is connected to the fixed connecting plate 35, and the transverse linear guide rail 37 is connected to the fixed plate 38. The slider of 7 is connected to the slider of the longitudinal linear guide rail 36. The fixed plate 38 is connected to the slide rail of the longitudinal linear guide rail 36. The finger cylinder 39 is installed on the fixed plate 38. The two output ends of the finger cylinder 39 are connected to the clamping plates 40. When working, the swing plate motor 32 drives the swing arm 33 to rotate counterclockwise by 125°, which drives the finger cylinder 39 and the clamping plates 40 below to slide in the longitudinal and lateral directions to realize the lifting, translation, and lowering of the clamping plates 40. The finger cylinder 39 drives the clamping plates 40 to clamp the steamed bun. The swing plate motor 32 rotates in the opposite direction by 125°, which drives the clamping plates 40 to rise, translate, and fall back to the original position. The finger cylinder 39 drives the clamping plates 40 to release the clamping of the steamed bun and place the steamed bun in the steaming tray.

[0041] like Figure 3 As shown, two spaced sensors 5 are installed on the lower frame 2. One sensor 5 is located below the front side of the tray-distributing assembly and is used to detect whether a steaming tray is placed on the tray support 4. The other sensor 5 is located below the front side of the tray-distributing mechanism and is used to sense whether the steaming tray has been delivered into place. Both sensors 5 are electrically connected to the electrical control system 43.

[0042] like Figure 1 and Figure 3 As shown, adjustable feet 41 and wheels 42 are installed at the four corners of the bottom of the lower frame 2. The wheels 42 facilitate the flexible movement of the whole unit, and the adjustable feet 41 provide stable support during operation.

[0043] The working principle of this utility model is as follows:

[0044] In standby mode, the vertical cylinder 6 is in the retracted state and the side cylinder 10 is in the extended state (original position). The two side plates 12 support the stacked steaming trays. The electrical control system 43 controls the vertical cylinder 6 to rise a distance H. After lifting the stacked steaming trays, the two side cylinders 10 retract and the vertical cylinder 6 descends a distance L (where H is greater than L, and the difference between H and L is the height of one steaming tray). The two side cylinders 10 extend to support the second and above steaming trays below. The bottom first steaming tray is separated. The vertical cylinder 6 continues to descend to the original position and places the first steaming tray on the tray support 4. At this time, the sensor 5 on the lower front side of the tray-separating assembly senses the steaming tray, the tray-feeding motor 13 starts, and the pusher claw 22 on the tray-feeding chain 21 takes away the steaming tray on the tray support 4 and transports it to the sensor 5 on the lower front side of the tray-sanding mechanism. The sensor 5 senses the steaming tray and stops transporting, waiting for the tray to be placed. After the steaming tray on the tray support 4 is taken away, the vertical cylinder 6 rises a distance H again and enters the next cycle.

[0045] The steamed buns conveyed by the shaping machine (not shown in the figure) are sensed by the induction switch 30 in the steamed bun conveying mechanism to realize intermittent step conveying. After the electrical control system 43 senses the set number of steamed buns, the tray placement mechanism starts to work. The electrical control system 43 controls the finger cylinder 39 to drive the clamping plate 40 to pick up the steamed buns. Then the tray placement motor 32 rotates 125° counterclockwise, so that the clamping plate 40 carries the steamed buns up, down, and down. After they fall to the position of the steaming tray, the finger cylinder 39 drives the clamping plate 40 to open and place a row of steamed buns in the steaming tray. The tray placement motor 32 rotates 125° in the opposite direction, driving the clamping plate 40 back to the original position above the conveyor belt 26. Then, according to the set number of rows and row spacing, the electrical control system 43 controls the tray pushing mechanism to push the steaming tray to move the corresponding row spacing and number of times, and cooperates with the tray placement mechanism to fill the entire steaming tray in sequence.

[0046] Repeat the above steps to plate the next dish.

[0047] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent changes and modifications made in accordance with the scope of the claims of this utility model should fall within the technical scope of this utility model.
