A mechanical arm 28 is located at the tail end of the curved belt conveyor 2, and the mechanical arm 28 is a six-axis industrial mechanical arm 28 of model HSR-JR607-730. Both sides of the mechanical arm 28 are provided with placing tables 29, one of which is provided with empty meal boxes 30, and the other of which is provided with meal boxes filled with food materials 31. The mechanical arm 28 performs the following actions (for reference to the use state diagram of the mechanical arm 28 shown in Figure 2 ): first, the empty meal boxes 30 are taken from the placing table 29, and then the empty meal boxes 30 are placed at the tail end of the curved belt conveyor 2 to receive the conveyed food materials; after the meal boxes are filled with food materials, the meal boxes filled with food materials are transferred to the corresponding placing table 29 provided with the meal boxes filled with food materials 31.

[0040] The silk block food material after blanching needs to be cooled and washed, which can quickly reduce the temperature of the food material, maintain the taste (such as crispness) and color of the food material, and wash off the floating scum, impurities or excess starch on the surface of the food material (for example, the blanched potato silk is cooled and washed); in view of the above problems, the silk block processing device of the present application can solve the above problems.

The material guiding mechanism serving as an intermediate connecting component is also fixedly connected to the base 1, the feeding end receives the vegetable leaves sent by the conveying mechanism, and the discharge end is butted with the feeding port of the dehydration mechanism, so as to guide the vegetable leaves from the conveying mechanism to the dehydration mechanism. The dehydration mechanism is fixed to the base 1 on one side of the material guiding mechanism, and the vegetable leaves enter the dehydration mechanism through the material guiding mechanism and complete the dehydration treatment in the dehydration mechanism.

[0046] The conveying mechanism is arranged, and the following beneficial effects are obtained: while realizing the conveying function of the leaf, the driving unit composed of the electric telescopic cylinder 13, the rudder 14 and the transmission rod 15 is used for tension adjustment of the conveying belt 12, so that the stable operation of the conveying belt 12 is guaranteed, the slip is avoided, the conveying efficiency and reliability of the leaf are improved, and the service life of the conveying belt 12 is prolonged.

[0047] More specifically, with reference to Figure 6 The guide material mechanism is in the form of a platform shape, has a connecting form suitable for the discharging end of the conveying mechanism and the feeding port of the dehydration mechanism, and provides a guide transmission path for the leaf from the conveying mechanism to the dehydration mechanism;The guide channel 16 above the guide material mechanism is in L shape, and the two ends are respectively connected with the conveying mechanism and the dehydration mechanism;The bracket 17 below the guide material mechanism is fixed on the base 1.

[0048] More specifically, with reference to Figure 8 , it is shown that the independent structure schematic diagram of the dehydration mechanism, from the figure, the dehydration mechanism includes the support 18, the support 18 is fixed on the base 1, and the servo motor 19 is installed on the top of the support 18 (the servo motor 19 is specifically a double-shaft servo motor 19 with the model ABB3HAC055433-001);The spin-drying cylinder 20 is located above the servo motor 19, the cylinder body is provided with a plurality of through holes 21, and the inner wall is provided with a spiral baffle 22 (such as Figure 10 ​The spiral baffle 22 is installed as shown in the installation schematic diagram of the spiral baffle 22 shown in Figure 1); four lifting rollers 23 are arranged at the four corners of the top of the support base 18, and annular tracks 24 are concentrically sleeved and fixed at the two ends of the spin-drying cylinder 20; the annular track 24 on the left side is in contact with the two lifting rollers 23 on the left side, and the annular track 24 on the right side is in contact with the two lifting rollers 23 on the right side.

The cover 27 is installed above the servo motor 19 on the top of the support base 18, and the main function is protection, which can prevent the water and impurities spun out during the dehydration operation from contacting the servo motor 19, the driving gear 25 and other components, so as to avoid damage caused by moisture and impurities, and ensure the normal operation and service life of the equipment.

[0049] During operation, the two shafts of the servo motor 19 drive the two driving gears 25 to rotate, the driving gears 25 drive the driven gears 26 to rotate, and the spin-drying cylinder 20 is indirectly driven to rotate; the lifting rollers 23 cooperate with the annular tracks 24 to support and assist the rotation of the spin-drying cylinder 20.

[0055] Step 4 (packaging processing): The existing packaging equipment (for example, the full-automatic aluminum foil sealing machine with model LK-400B, which is not described here) is used to package the meal box 31 filled with materials.

[0056] The present application has the following advantages:

[0057] The present application solves the problem of how to spin-dry the cleaned leafy vegetable materials; specifically, first, for the silk block materials, the silk block processing device is used for cooling and washing, which can quickly cool the materials to maintain the crisp and tender taste and original color, wash the surface foam, impurities or excess starch, and reuse the filtered water through the water circulation system (water collecting tank 6, circulating pump 11, U-shaped spray pipe 8) to save water resources; second, for the leafy vegetable materials, the conveying mechanism of the leafy vegetable processing device can adjust the tension of the conveying belt 12 through the driving unit to avoid slipping, improve the conveying stability and efficiency, and prolong the service life of the conveying belt 12; the dehydration mechanism is driven by the double-shaft servo motor 19 to stably overturn the spin-drying cylinder 20, the spiral baffle 22 guides the leafy vegetables to move in an orderly manner without accumulation, the through hole 21 of the cylinder body realizes uniform dehydration, the lifting roller 23 and the annular track 24 reduce the running wear, the cover 27 protects the core component servo motor 19 from the influence of water and impurities to prolong the service life, and the dehydrated leafy vegetables can be directly connected to the curved conveyor without the need for secondary transfer; third, the overall equipment takes the 90-degree curved belt conveyor 2 as the core conveying carrier, and the six-axis industrial mechanical arm 28 automatically completes the operations of taking the box, receiving the materials, moving the box, and loading the tray, the devices are cooperatively linked to reduce manual intervention and improve the overall efficiency and automation degree of the central kitchen for pre-preparing and loading the dishes.

[0058] In the field of food processing technology, blanching is a common sterilization, deoxycalcification and shaping process in the pretreatment process of silk block materials (such as shredded radish and potato pieces) and leafy vegetable materials (such as spinach leaves and cabbage leaves).

[0059] In the prior art, the two types of food materials are usually only subjected to cold water soaking or spraying. However, it is found in practice that the cold water exchange is inefficient, and the center of the food material is not cooled completely. Especially for the silk block food material in a stacked state, it is difficult for the cold water to penetrate into the interior, and the outer layer is cooled while the inner layer is still at a high temperature. For the leafy food material, the leaf is thin and easy to stick together, and the cold water can only act on the surface layer, and the heat in the inner layer cannot be quickly dissipated, resulting in poor overall cooling effect, which affects the subsequent food processing quality and eating experience. To solve the above technical problems, the present application further provides a silk block processing device and a leaf processing device, and a cooling device 32 is arranged on the side of the silk block processing device and the leaf processing device, respectively. Through the synergistic effect of air cooling and cold water cooling, the cooling efficiency and uniformity of the two types of food materials after blanching are improved, and the specific structure is as follows.

[0060] Reference Figure 11 The installation structure of the cooling device 32 is shown in the figure. As can be seen from the figure, the cooling device 32 directly selects a cooling machine with a model of Macpan BLC5.20Eco. Two cooling devices 32 are arranged on the side of the silk block processing device and the leaf processing device, respectively. The top of the cooling device 32 is provided with a heat dissipation port 33, and the side end of the cooling device 32 is provided with an air outlet pipe 34. The air outlet pipe 34 close to the silk block processing device is arranged in the washing tank 3, and the air outlet pipe 34 close to the leaf processing device is arranged in the spin-drying cylinder 20. The cold air blown out of the air outlet pipe 34 is used for air cooling of the silk block food material or the leaf food material.

[0061] In the industrial production process of the prepared food, the transfer operation of the silk block food material (such as carrot block, potato strip, etc.) and the leaf food material (such as lettuce leaf, baby corn leaf, etc.) needs to adapt to the diversified production needs. Some prepared food only needs a single silk block food material or a single leaf food material, and some prepared food needs a mixture of the two types of food materials.

[0062] To solve the above technical problems, the present application optimizes the feeding mode of the silk block processing device and the leaf processing device to realize the synchronous operation of single food material transfer and mixed two types of food material transfer. The specific optimization scheme is as follows:

[0063] In the use process, the silk block processing device first feeds the silk block food material to the curved belt conveyor 2 in an intermittent manner, so as to form a plurality of linearly arranged “silk block food material small piles” on the curved belt conveyor 2. Further, according to the preparation requirements of the prepared food, the leaf processing device can feed the leaf food material to the side of the silk block food material (at this time, two types of “single food material small piles” will be formed on the curved belt conveyor 2, such as the transfer display of two types of single food material shown in Figure 12 In the use process, the silk block processing device first feeds the silk block food material to the curved belt conveyor 2 in an intermittent manner, so as to form a plurality of linearly arranged “silk block food material small piles” on the curved belt conveyor 2. Further, according to the preparation requirements of the prepared food, the leaf processing device can feed the leaf food material to the side of the silk block food material (at this time, two types of “single food material small piles” will be formed on the curved belt conveyor 2, such as the transfer display of two types of single food material shown inFigure 13 (The diagram shows the transfer of mixed food items).

[0064] Because there are two scenarios: "single ingredient" and "mixed ingredient piles," it is necessary to promptly separate the "small piles of single ingredients" and the "mixed ingredient piles" at the discharge end of the curved belt conveyor 2 to facilitate the robotic arm 28 in quickly receiving the required ingredients using the lunchbox. To address the aforementioned issues, this application further optimizes the curved belt conveyor 2, referring to... Figure 14 The diagram shows the installation structure of the optimized curved belt conveyor 2. As can be seen from the diagram, the curved belt conveyor 2 also includes a food sorting mechanism. The food sorting mechanism is located at the tail end of the belt of the curved belt conveyor 2. The food sorting mechanism is used to transfer and separate "single food" and "mixed food" to different receiving belts. The specific scheme is as follows.

[0065] refer to Figures 15-16 ,in, Figure 15 This diagram illustrates the first usage state of the food sorting system, while Figure 16 The diagram shows the second usage state of the food sorting mechanism. As can be seen from the two diagrams above, the food sorting mechanism includes a support frame 35, which is located at the tail end of the curved belt conveyor 2, serving as the mounting carrier for the first receiving belt conveyor 36 and the second receiving belt conveyor 37. The first receiving belt conveyor 36 and the second receiving belt conveyor 37 are respectively arranged on the upper and lower sides of the support frame 35 from top to bottom. The frame of the first receiving belt conveyor 36 is rotatably connected to the adjacent side of the support frame 35 via a pin 38, and the frame of the second receiving belt conveyor 37 is also rotatably connected to the adjacent side of the support frame 35 via a pin 38. The hydraulic telescopic rod 39 is a double-mounted HOB-80×100-S type. The hydraulic telescopic rod 39 has two output ends that are rotatably connected to the frames of the first receiving conveyor belt 36 and the second receiving conveyor belt 37, respectively, to achieve synchronous rotation and linkage between the two. The rotary motor 40 is mounted on the support frame 35, and the output shaft of the rotary motor 40 is concentrically fixedly connected to the pin 38 on the frame of the first receiving conveyor belt 36, providing power for the rotation of the first receiving conveyor belt 36. The baffle 41 is installed at the tail end of the belt of the curved belt conveyor 2 and is positioned between the first receiving conveyor belt 36 and the second receiving conveyor belt 37. The baffle 41 limits the movement of the first receiving conveyor belt 36 and the second receiving conveyor belt 37 on the one hand, and guides the food to fall smoothly onto the second receiving conveyor belt 37 on the other hand.

[0066] In use, the rotary motor 40 is started to drive the first receiving belt conveyor 36 to rotate upward or downward around the pin shaft 38 through forward and reverse rotation of the rotary motor 40; due to the linkage of the hydraulic telescopic rod 39, the second receiving belt conveyor 37 will be synchronized to rotate with the first receiving belt conveyor 36. As shown in FIG. 2, Figure 15 When the first receiving belt conveyor 36 is opposite to the tail end of the curved belt conveyor 2, it can receive one type of food materials, and at this time, the second receiving belt conveyor 37 is away from the tail end of the curved belt conveyor 2; as shown in FIG. 3, Figure 16 When the second receiving belt conveyor 37 is opposite to the tail end of the curved belt conveyor 2, it can receive another type of food materials, thereby realizing the classified receiving operation of different types of food materials.

[0067] In combination with the above connection relationship, the beneficial effects of the food material classification mechanism are as follows:

[0068] Firstly, the "single food material small pile" and the "food material mixed pile" can be separated, which meets the demand of different pre-prepared dishes for food material types and avoids confusion before plating. Secondly, the rotary motor 40 provides power to synchronize the rotation of the two receiving belt conveyors through the hydraulic telescopic rod 39, without manual operation, and quickly completes the classified receiving of different food materials. Thirdly, the support frame 35 stabilizes the equipment structure, the baffle 41 limits the position of the receiving belt conveyor and guides the falling of food materials, avoids the falling or jamming of food materials, and ensures smooth conveying.

[0069] After the food material classification mechanism separates the "single food material" from the "food material mixed pile", the empty meal box 30 needs to be transported to the corresponding receiving belt conveyor to receive food materials in time. In order to improve the connection efficiency and optimize the operation of the mechanical arm 28, the present application further designs a meal box transfer mechanism based on the installation structure of the meal box transfer mechanism shown in FIG. 6. Figure 17 The meal box transfer mechanism is in driving connection with the food material classification mechanism, and is arranged on the base 1. The mechanical arm 28 only needs to "place the empty box to the transfer mechanism and take the full box from the transfer mechanism". Without the transfer mechanism, the mechanical arm 28 needs to directly connect to the receiving belt conveyor with dynamic switching position, which is easy to cause the empty box to be not in place in time, food materials to wait or meal boxes to be offset and spilled due to the complex action logic and delayed path adjustment. The specific structure of the meal box transfer mechanism is as follows.

[0070] Referring to FIG. 6, Figure 18As shown in the enlarged structural schematic view of the meal box transfer mechanism, the meal box transfer mechanism comprises a guide frame 42 fixed on the base 1 to provide sliding guidance for a first toothed plate 43 and a second toothed plate 44; the first toothed plate 43 is slidingly connected to the top of the guide frame 42, and the second toothed plate 44 is slidingly connected to the bottom of the guide frame 42; a circular toothed disc 45 is fixedly connected in concentricity with the pin shaft 38 on the rack of the second receiving belt conveyor 37 and rotates synchronously with the overturning action of the second receiving belt conveyor 37; the first toothed plate 43 and the second toothed plate 44 are respectively adapted to engage with the two sides of the circular toothed disc 45, and the forward and reverse rotation of the circular toothed disc 45 can drive the first toothed plate 43 and the second toothed plate 44 to slide along the guide frame 42; a first clamp 46 is connected to the first toothed plate 43 and moves with the first toothed plate 43; a second clamp 47 is connected to the second toothed plate 44 and moves with the second toothed plate 44; the slot portions of the first clamp 46 and the second clamp 47 are used for placing meal boxes to realize the carrying and transferring of the meal boxes.

[0071] In the first case, when the first receiving belt conveyor 36 approaches the upper side of the baffle 41, the second receiving belt conveyor 37 is away from the lower side of the baffle 41, the circular toothed disc 45 rotates clockwise with the linkage of the second receiving belt conveyor 37, drives the first toothed plate 43 to slide along the guide frame 42, and the second toothed plate 44 moves in the opposite direction of the movement of the first toothed plate 43, so that the first clamp 46 carries the meal boxes to approach the tail end of the belt of the curved belt conveyor 2, and at this time, the second clamp 47 carries the meal boxes away from the tail end.

[0072] In the second case, when the first receiving belt conveyor 36 is away from the upper side of the baffle 41, the second receiving belt conveyor 37 approaches the lower side of the baffle 41, the circular toothed disc 45 rotates counterclockwise with the linkage of the second receiving belt conveyor 37, drives the first toothed plate 43 to slide along the guide frame 42, and the second toothed plate 44 moves in the opposite direction of the movement of the first toothed plate 43, so that the first clamp 46 carries the meal boxes away from the tail end, and at this time, the second clamp 47 carries the meal boxes to approach the tail end.

[0073] The meal box transfer mechanism has the following beneficial effects: first, the meal box transfer mechanism is linked with the food material classification mechanism synchronously, the toothed plate is driven to slide by the circular toothed disc 45, the meal box is accurately connected with the receiving belt conveyor, and there is no connection delay; second, the action of the mechanical arm 28 is simplified, the mechanical arm 28 only needs to fixedly execute the actions of “emptying the box” and “taking the full box”, the path needs not to be frequently adjusted, the operation efficiency and accuracy are improved; and third, the two clamps respectively carry the meal boxes of corresponding food materials, the preparation of the meal boxes of two types of food materials can be completed in parallel, the classification demand is adapted, and the tray filling efficiency is improved.
