Description

Technical Field

[0001] The invention relates to the field of processing equipment for baked foods, and in particular to a baking tray cleaning system. Background Art

[0002] Baking trays are common containers for making baked goods. After baking, when the baked food is taken off, some residues and debris will inevitably adhere to the baking tray. Traditional baking tray cleaning operations are all performed by assembly line workers. Workers use brushes to clean the residues on the baking tray. Some large and difficult-to-clean residues are removed with shovels. However, due to the different degrees of manual cleaning, the inner wall of the baking tray may be damaged. In addition, the labor production cost is high, the manual cleaning operation efficiency is slow, and the cleaning effect is not ideal. The fine granular foreign matter remaining on the baking tray is difficult to distinguish with the naked eye, but it still remains in the baking tray. If these foreign matter are ignored, the baking materials will be contaminated when the baking tray is reused next time, which makes it difficult to ensure the quality of the finished baked food, reduce the product qualification rate, and even endanger life and health after eating the contaminated baked food.

In this embodiment, the controller can be a data processing device such as MCU or a single-chip microcomputer, and preferably, it also includes a plurality of baking tray sensors. At least one baking tray sensor is correspondingly arranged in the working areas corresponding to the scraping mechanism 2, the rolling brush mechanism 3 and the brush mechanism 4, which are used to detect whether there is a baking tray in the corresponding working areas. If so, the corresponding mechanism is driven to perform corresponding cleaning operations. Preferably, the baking tray sensor can be an infrared sensor.

[0038] Specifically, the chuck mechanism 1 includes a chuck bracket 11 arranged above the input end of the conveying mechanism 7, a chuck device 12 for transferring the baking tray, a lifting support plate 13 for moving the baking tray toward the chuck device 12, and a sensor arranged at the chuck device 12.

The baking tray feed sensor 14 can also be an infrared sensor. In this embodiment, the chuck mechanism 1 is set to the input end of the conveying mechanism 7, so that the stacked baking trays are put into the conveying mechanism 7 one by one for cleaning. Specifically, the trapezoidal screw 18 is set vertically so that the lifting plate 13 can move upward or downward along the trapezoidal screw 18. In this embodiment, the baking trays are collected by a trolley or other tools (in this embodiment, the tool for collecting the baking trays is preferably a trolley), and then transported to the lifting plate 13. At this time, the lifting plate 13 should be at the end of the trapezoidal screw 18 away from the chuck device 12. The trolley is directly parked on the lifting plate 13, and then the baking tray cleaning system is powered on. The lifting drive drives the lifting plate 13 to move upward with the trolley full of baking trays through the trapezoidal screw 18. When the baking tray feeding sensor 14 senses that the baking tray at the top of the trolley has reached a preset height (the baking tray feeding sensor 14 can also be pre-set at a preset height, and then detect whether there is a baking tray on the same horizontal plane), then the translation component 16 drives the chuck device 12 to move above the baking tray, and the lifting and lowering Component 17 drives the chuck device 12 to descend and clamp the baking tray, and then the lifting component 17 drives the chuck device 12 to clamp the baking tray and rise to a height level with the input end of the conveying mechanism 7, and the translation component 16 then drives the chuck device 12 to move the baking tray to the input end of the conveying mechanism 7, and repeats multiple times until the trolley rises to a preset height, and the lifting pallet 13 lowers the trolley to the ground, and replaces it with another trolley full of baking trays to be cleaned. Furthermore, eccentric wheels are also provided on both sides of the input end of the conveying mechanism 7, and the shaft core of the eccentric wheel is solid round steel, and the surface of the solid round steel is covered with high-strength soft rubber. When the chuck mechanism 1 conveys the baking tray to the input end of the conveying mechanism 7, the eccentric wheel uses its own gravity to press the baking tray to prevent the baking tray from slipping, so that the baking tray can enter the conveying mechanism 7.

[0039] Preferably, the chuck device 12 comprises a pressure plate 121 with a clamping window 125 at both ends along the long side direction and two clamping assemblies 122, the upper end surface of the pressure plate 121 is extended upward along the long side direction to form an extension part 123, the lifting assembly 17 is rotatably connected to the middle part of the extension part 123, the two clamping assemblies 122 are symmetrically arranged with the lifting assembly 17 as the symmetry axis, the clamping assembly 122 comprises an upper rotating shaft 1221, a lower rotating shaft 1222, an elastic leveling element 1223, a connecting rod 1224, a clamping cylinder 1225 and a clamping plate 1226, the connecting rod 1224 is self-closed The lifting assembly 17 is tilted downward in a direction away from the lifting assembly 17, the upper shaft 1221 is connected to the lifting assembly 17, one end of the connecting rod 1224 is rotatably connected to the upper shaft 1221, the other end of the connecting rod 1224 is rotatably connected to the extension part 123 through the lower shaft 1222, the upper shaft 1221 is connected to the pressure plate 121 through an elastic leveling element 1223, the clamping plate 1226 is movably connected in the clamping window 125, the clamping cylinder 1225 is connected to an end face of the clamping plate 1226 close to the lifting assembly 17, and the clamping cylinder 1225 is connected to a controller. In this embodiment, when the clamping device 12 clamps the baking tray, the lower end surface of the pressing plate 121 abuts against the baking tray and fits with it under the drive of the lifting component 17 (during the abutting process, the pressing plate 121 will rotate around the connection point between the lifting component 17 and the extension part 123 until the lower end surface is parallel to the baking tray. When the baking tray itself is in a tilted state, the elastic leveling elements 1223 on the left and right sides of the lifting component 17 will be deformed by pressure during the rotation process). Then, the clamping plates 1226 in the clamping windows 125 at both ends of the pressing plate 121 are in contact with each other. Driven by the corresponding clamping cylinder 1225, they move towards each other and thus clamp the baking tray, and then the lifting assembly 17 drives the pressure plate 121 and the clamped baking tray to rise. During the rising process, the elastic leveling elements 1223 on the left and right sides of the lifting assembly 17 are no longer subjected to force and recover their deformation, thereby driving the pressure plate 121 in contact with the baking tray to restore its original horizontal state, and then leveling the baking tray to achieve the purpose of self-leveling, so that all baking trays entering the conveying mechanism 7 are level, avoiding the situation of chucks or ineffective cleaning.

[0040] Furthermore, the chuck device 12 includes an adsorption plate for adsorbing the baking tray and two clamping assemblies 122, the upper end surface of the adsorption plate extends upward along the long side direction to form an extension portion 123, the lifting assembly 17 is rotatably connected to the middle part of the extension portion 123, the two clamping assemblies 122 are symmetrically arranged with the lifting assembly 17 as the symmetry axis, the clamping assembly 122 includes an upper rotating shaft 1221, a lower rotating shaft 1222, an elastic leveling element 1223 and a connecting rod 1224, the connecting rod 1224 is tilted downward from close to the lifting assembly 17 to away from the lifting assembly 17, the upper rotating shaft 1221 is connected to the lifting assembly 17, one end of the connecting rod 1224 is rotatably connected to the upper rotating shaft 1221, the other end of the connecting rod 1224 is rotatably connected to the extension portion 123 through the lower rotating shaft 1222, the upper rotating shaft 1221 is connected to the pressing plate 121 through the elastic leveling element 1223, and the adsorption plate is connected to the controller. In this embodiment, the chuck device 12 can also realize "clamping" of the baking tray in the form of adsorption. Preferably, the adsorption plate can be an electromagnet or a component with a built-in electromagnet. When the baking tray needs to be transported, the electromagnet is energized.

[0041] Furthermore, a negative pressure suction cup can be provided at the lower end of the adsorption plate (no need to set up an electromagnet and a clamping cylinder 1225), and the negative pressure suction cup can be used to directly adsorb the baking tray on the trolley, and then transferred to the input end of the conveying mechanism 7; preferably, two or more of the negative pressure suction cup, electromagnet and clamping cylinder 1225 can be combined to improve the stability and reliability of clamping.

[0042] Preferably, the elastic leveling element 1223 may be a spring, the lifting drive member may be a motor, and the translation assembly 16, the lifting assembly 17 and the clamping cylinder 1225 may all be hydraulic devices or cylinders.

[0043] Specifically, the scraping mechanism 2 includes a scraping bracket 21 arranged above the conveying mechanism 7, the lower end face of the scraping bracket 21 is connected to a scraping driving member 22, the output end of the scraping driving member 22 is connected to a buffer plate 23, the lower end face of the buffer plate 23 is provided with an elastic shrinking member 24, the lower end of the elastic shrinking member 24 is connected to a scraper 25 for scraping off the residue on the baking tray, and the scraping driving member 22 is connected to a controller. Preferably, the scraper drive 22 can be a cylinder, the elastic contraction member 24 can be a spring, and the scraper 25 is preferably made of polytetrafluoroethylene, that is, a food-grade material, and is soft and does not damage the baking tray. When the baking tray sensor in the working area corresponding to the scraper mechanism 2 senses the baking tray, the scraper drive 22 drives the scraper 25 to move downward and abut against the baking tray, and at the same time the conveying mechanism 7 continues to drive the baking tray to move along the conveying direction, thereby achieving scraping; preferably, the buffer plate 23 is directly connected to the output end of the scraper drive 22, and the upper end of the scraper 25 abutting against the baking tray is connected to the buffer plate 23 through the elastic contraction member 24. By utilizing the elasticity of the elastic contraction member 24, when the scraper 25 passes through an uneven position on the baking tray, the scraper 25 can automatically shrink and fluctuate, thereby achieving the purpose of cleaning and avoiding the deformed baking tray from being stuck in the scraper mechanism 2.

[0044] Specifically, the roller brush mechanism 3 includes a spiral roller brush 31 for cleaning the baking tray and a roller brush bracket 32 ​​arranged between the scraping mechanism 2 and the brush mechanism 4, the spiral roller brush 31 includes a roller brush roller 311 and bristles 312 spirally arranged on the surface of the roller, both ends of the roller are connected to a roller brush adjustment plate 33, a first adjustment shaft 34 is rotatably connected between the lower end of the roller brush adjustment plate 33 and the cleaning platform 8, the roller brush bracket 32 ​​is connected to a first pushing cylinder 35, a roller brush shaft 36 is rotatably connected between the output end of the first pushing cylinder 35 and the upper end of the roller brush adjustment plate 33, and the first pushing cylinder 35 is connected to a controller. Preferably, the bristles 312 are made of nylon and have a length of 70 mm to 80 mm. When the baking tray sensor in the working area corresponding to the roller brush mechanism 3 senses the baking tray, the first push cylinder 35 drives the roller brush adjustment plate 33 to drive the spiral roller brush 31 to rotate around the first adjustment shaft 34 through the roller brush shaft 36, so that the bristles 312 of the spiral roller brush 31 are pressed against the baking tray, and under the rotation of the roller brush drum 311, the bristles 312 of the spiral roller brush 31 roll to clean the baking tray, wherein the rotation direction of the roller brush drum 311 is opposite to the conveying direction, so that the baking tray can be cleaned under the conveying of the conveying mechanism 7. In this embodiment, the friction layer 72 made of high-quality soft glue or silicone on the surface of the conveying mechanism 7 is used to increase the friction between the conveying mechanism 7 and the baking tray. The force ensures that the baking tray can still move along the conveying direction under the influence of the reverse rotation of the roller brush drum 311. Preferably, the rotation direction of the roller brush drum 311 is opposite to the conveying direction, that is, the direction of the friction force provided to the baking tray by the bristles 312 that rotate with the roller brush drum 311 is opposite to the conveying direction. At the same time, the friction force provided to the baking tray by the bristles 312 is less than the friction force provided to the baking tray by the conveying mechanism 7, thereby ensuring that the cleaning of the spiral roller brush 31 will not cause the baking tray to slip or even be thrown out of the outside, and the situation that it cannot be effectively cleaned, and the force on the residue on the baking tray is increased (the friction force provided to the baking tray by the bristles 312 and the friction force provided to the baking tray by the conveying mechanism 7 will be superimposed on the residue), thereby improving the cleaning effect of the spiral roller brush 31.

[0045] Preferably, the bristles 312 are spirally arranged on the surface of the drum, so that when cleaning the baking tray, the bristles 312 cooperate with the rotation of the drum to discharge the residues on the baking tray in a spiral manner, thereby preventing the residues on the baking tray from getting stuck on the bristles 312, thereby improving the use efficiency of the bristles 312 and reducing the cleaning process of subsequent equipment.

[0046] Specifically, the brush mechanism 4 includes a brush assembly 41 for wiping the baking tray and a brush bracket 42 arranged between the roller brush mechanism 3 and the plate pushing mechanism 5, the brush assembly 41 includes a brush roller 411, a clamping tooth base 412 arranged on the brush roller 411 along the circumferential direction, a brush 413, a first spring hinge 414, a movable clamping block 415 and a fixed clamping block 416, one end of the movable clamping block 415 is movably connected to one long side of the clamping tooth base 412 through the first spring hinge 414, and the other long side of the clamping tooth base 412 is connected to the fixed clamping block 416. The edge is fixedly connected to one end of the fixed clamp 416, and the other end of the movable clamp 415 and the other end of the fixed clamp 416 are both detachably connected to the brush 413. Both ends of the brush roller 411 are connected to a brush adjustment plate 43, and a second adjustment shaft 44 is rotatably connected between the lower end of the brush adjustment plate 43 and the cleaning platform 8. The brush bracket 42 is connected to a second pushing cylinder 45, and a brush shaft 46 is connected between the output end of the second pushing cylinder 45 and the upper end of the brush adjustment plate 43, and the second pushing cylinder 45 is connected to a controller. The preferred brush 413 can be made of an ordinary pure cotton towel folded, that is, the folded or multiple overlapping towels are clamped in the movable clamp block 415 and the fixed clamp block 416 to form the brush 413; in addition, the conventional spring hinge supports two states of fully open and fully closed, and automatically closes in the middle state. In this embodiment, the other end of the movable clamp block 415 extends a first clamping tooth in the direction of the fixed clamping tooth, and the other end of the fixed clamp block 416 extends in the direction of the movable clamp block to form a second clamping tooth that meshes with the first clamp, so as to facilitate clamping the towel by the first clamping tooth and the second clamping tooth. When installing the brush 413, the clamped movable clamp block 415 is pried open, that is, the movable clamp block 415 is driven to rotate around the first spring hinge 414. At this time, the first spring hinge 414 is in an intermediate state or a fully open state. Then, the towel is placed between the toothed structures of the two relatively arranged movable clamp blocks 415, and then the first spring hinge 414 is driven to be in a fully closed state. The elastic towel of the first spring hinge 414 is clamped between the toothed structures of the two relatively arranged movable clamp blocks 415. When replacing the towel, the clamped movable clamp block 415 is directly pried open, that is, the movable clamp block 415 is driven to rotate around the first spring hinge 414. At this time, the first spring hinge 414 is in an intermediate state or a fully open state, and the towel can be taken out for replacement, thereby realizing rapid disassembly and assembly of cleaning consumables.

[0047] When the baking tray sensor in the working area corresponding to the brush mechanism 4 senses the baking tray, the second pushing cylinder 45 drives the brush adjusting plate 43 to drive the brush 413 to rotate around the second adjusting rotating shaft 44 through the brush rotating shaft 46, and under the rotation of the brush roller 411, the brush 413 rolls and wipes the baking tray, wherein the rotation direction of the brush roller 411 is opposite to the conveying direction, so that the baking tray can be wiped under the conveyance of the conveying mechanism 7. In this embodiment, the friction layer 72 made of high-strength soft glue or silicone on the surface of the conveying mechanism 7 is used to increase the friction force between the conveying mechanism 7 and the baking tray, ensuring that the baking tray can still be moved under the influence of the reverse rotation of the brush roller 411. The brush roller 411 moves along the conveying direction. Preferably, the rotation direction of the brush roller 411 is opposite to the conveying direction, that is, the direction of the friction force provided to the baking tray by the brush 413 rotating with the brush roller 411 is opposite to the conveying direction. At the same time, the friction force provided to the baking tray by the brush 413 is smaller than the friction force provided to the baking tray by the conveying mechanism 7, thereby ensuring that the wiping of the brush 413 will not cause the baking tray to slip or even be thrown out of the outside, and will not be able to be effectively cleaned, and the force on the residue on the baking tray is increased (the friction force provided by the brush 413 to the baking tray and the friction force provided by the conveying mechanism 7 to the baking tray will be superimposed on the residue), thereby improving the cleaning effect of wiping.

[0048] Specifically, it also includes a blowing mechanism 6, which includes a blowing component 61 and an oil spray component 62, the blowing component 61 includes an air pipeline 611 and a plurality of blowing nozzles 612 connected to the air pipeline 611, the blowing nozzles 612 are evenly spaced on the air pipeline 611, the air pipeline 611 is arranged between the brush mechanism 4 and the oil spray component 62, the oil spray component 62 includes an oil pipeline 621 and a plurality of oil spray nozzles 622 connected to the oil pipeline 621, the oil spray nozzles 622 are evenly spaced on the oil pipeline 621, and the oil pipeline 621 is arranged between the air pipeline 611 and the push plate mechanism 5. In this embodiment, after scraping, rolling and wiping, the baking tray is basically clean, but there may still be some smaller residues, so after wiping, the baking tray is blown by the blowing nozzle 612 in the blowing assembly 61, that is, the baking tray is blown clean by compressed air. After the blowing is completed, the baking tray is sprayed with oil by the oil spray nozzle 622 of the oil spray assembly 62, so that the baking tray is evenly sprayed with oil, saving the subsequent independent oil spraying process, so that the baking tray can be put into use directly, avoiding the problem of food cloth sticking to the baking tray, and making the food baked on the baking tray evenly sprayed with oil have a uniform color.

[0049] Specifically, the pushing plate mechanism 5 includes a pushing plate bracket 51, a descending support plate 52 and a baking plate discharging sensor 53 arranged at the output end of the conveying mechanism 7. The pushing plate bracket 51 extends in a direction away from the chuck mechanism 1 to form a discharging frame 54. The lower end of the discharging frame 54 is connected with a pushing plate driving member 55, and the lower end of the pushing plate driving member 55 is connected with a pushing plate plate 56. The lower end of the pushing plate plate 56 is connected with a chuck plate 57. A second spring hinge 58 is connected between the end surface of the chuck plate away from the conveying mechanism 7 and the end surface of the pushing plate plate 56 away from the conveying mechanism 7. The baking plate discharging sensor 53 is connected to one end of the discharging frame 54 away from the conveying mechanism 7. The descending support plate 52 is arranged below the pushing plate bracket 51. One end of the descending support plate 52 is connected with a screw rod 59, and the screw rod 59 is connected with a descending driving member. The descending driving member and the pushing plate driving member 55 are both connected to the controller. In this embodiment, the baking tray evenly sprayed with oil is transported to the tray mechanism by the conveying mechanism 7, and the tray pusher 55 drives the chuck plate 57 to push the baking tray that has reached the output end of the conveying mechanism 7 onto the trolley placed on the descending tray 52, and then the tray pusher 55 drives the chuck plate 57 to reset and push the next baking tray. When the chuck plate 57 is retracted, a baking tray is just transported out by the conveying mechanism, and then the chuck plate 57 abuts against the baking tray and rotates around the second spring hinge 58 in the direction away from the conveying mechanism, so that the baking tray is moved to the tray. To avoid the chuck plate 57 from getting stuck, when the baking tray discharge sensor 53 determines that there is a baking tray in the detection area (the plane where the preset height point is located), the descending drive component drives the descending pallet 52 with the trolley to move a baking tray to the position through the screw rod 59, and repeats this process multiple times so that the trolley gradually descends to the ground. The trolley is also filled with baking trays, which are then moved by the operator and replaced with another empty trolley on the descending pallet 52. The descending pallet 52 then raises the empty trolley to the preset height, and a new round of loading baking trays begins.

[0050] In this embodiment, a trolley filled with baking trays to be cleaned is parked on the lifting support plate 13 in advance, and an empty trolley is parked on the descending support plate 52. The descending support plate 52 lifts the empty trolley to a preset height, and then the cleaning system is powered on and started. The chuck device 12 is driven by the translation assembly 16 and the lifting assembly 17 to contact the baking tray on the trolley, and then the chuck device 12 clamps the baking tray and levels the baking tray. Then, the chuck device 12 is driven by the translation assembly 16 and the lifting assembly 17 to place the baking tray on the conveyor. On the conveying mechanism 7, when the chuck mechanism 1 conveys the baking tray to the input end of the conveying mechanism 7, the eccentric wheel uses its own gravity to press the baking tray to prevent the baking tray from slipping, so that the baking tray can enter the conveying mechanism 7. When the baking tray enters the working area of ​​the scraping mechanism 2, the scraping driving member 22 drives the scraper 25 to move downward to a height that abuts against the baking tray. At the same time, the conveying mechanism 7 drives the baking tray to move along the conveying direction, so that the scraper 25 scrapes away the residue in the baking tray. When the scraper 25 passes through the uneven position on the baking tray, the elastic contraction member 24 allows the scraper 25 to The brush 312 is automatically retracted and undulated, thereby cleaning the uneven positions. Then the baking tray enters the working area of ​​the roller brush mechanism 3. The bristles 312 spirally arranged on the surface of the roller are driven by the first push cylinder 35 to press the baking tray tightly, and the residues in the baking tray are efficiently discharged in a spiral rotation manner, so as to avoid the residues of the baking tray being stuck on the bristles 312, thereby improving the use efficiency of the bristles 312 and reducing the cleaning process of subsequent equipment. Then the baking tray enters the working area of ​​the brush mechanism 4, and the second push cylinder 45 drives the brush 413 to The baking tray is repeatedly wiped, and after wiping, the baking tray is blown by the blowing nozzle 612 in the blowing assembly 61, that is, the baking tray is blown clean by compressed air. After the blowing is completed, the baking tray is sprayed with oil by the oil spray nozzle 622 of the oil spray assembly 62, so that the baking tray is evenly sprayed with oil, saving the subsequent independent oil spraying process, so that the baking tray can be directly put into use, avoiding the problem of food cloth sticking to the baking tray, and making the food baked on the baking tray evenly sprayed with oil have uniform color, and finally the baking tray is pushed to the trolley by the tray pushing mechanism 5 for stacking.
