Description

Technical Field

[0001] This invention relates to the field of proofing device technology, specifically to a tower-type proofing device and method with multiple trays. Background Technology

[0002] For many pasta products, such as mooncakes, a proofing process is usually required during processing before further processing. Currently, the proofing process often involves manually moving baking trays containing food to a proofing room. This method is inefficient and can lead to food contamination during manual handling, posing a risk to food hygiene and safety.

[0003] Some people also use proofing towers to proof food, but most existing proofing towers only pass one baking tray at a time and do so continuously. This method is prone to causing the baking tray to fall off the proofing tower due to vibration, and overall, the proofing efficiency is still low. Summary of the Invention

[0004] In view of the shortcomings of the prior art, one of the objectives of the present invention is to provide a tower-type proofing device with multiple trays, which can solve the problem of completing the proofing operation with high efficiency;

[0005] The second objective of this invention is to provide a tower-style proofing method with multiple trays, which can solve the problem of completing the proofing operation with high efficiency.

[0006] One of the technical solutions to achieve the objective of this invention is: a multi-plate tower-type proofing device, comprising a feeding device, a proofing tower, and a discharging device, wherein the feeding device is located on one side of the proofing tower, and the discharging device is located at the bottom inside the proofing tower.

[0007] The feeding device is used to raise the baking trays one by one to the corresponding height and send them into the proofing tower. The proofing tower is used to receive the baking trays from the feeding device, and after arranging the baking trays in a row in the horizontal direction, the entire row of baking trays is lowered to the corresponding height one by one for proofing. The baking trays after proofing are then output through the delivery device.

[0008] Furthermore, the proofing tower includes a conveying mechanism and several tower units sequentially connected together. The conveying mechanism passes through each tower unit and is fixedly installed on the tower unit. One end of the conveying mechanism extends into the feeding device to support the baking trays that have risen to the corresponding height position within the feeding device and to feed the baking trays one by one into the end of the conveying mechanism away from the feeding device, thereby arranging the baking trays in a row on the conveying mechanism.

[0009] The tower unit is used to receive a whole row of baking trays on the transmission mechanism and lower them to the corresponding height for proofing. It then sequentially transfers the proofed baking trays to the delivery device.

[0010] Furthermore, the feeding device includes a frame and a conveying mechanism. The conveying mechanism is located within the frame, and includes a first motor, a first driving gear, a first conveying chain, a first driven gear, and several receiving plates mounted on the frame. The first motor is drive-connected to the first driving gear. The two ends of the first conveying chain are sleeved on the first driving gear and the first driven gear, so that the first driving gear and the first driven gear are drive-connected. The receiving plates are linked to the first conveying chain.

[0011] The receiving plate is used to support the baking tray on the conveying mechanism when it reaches the preset position, and the first conveying chain is used to lift the baking tray on the receiving plate to the corresponding height position under the drive of the first motor.

[0012] Furthermore, the first motor is connected to the first drive gear via the first bevel tooth, the drive shaft, and the second bevel tooth. The output shaft of the first motor is connected to the drive shaft. The second bevel tooth is fixedly sleeved on the drive shaft. The second bevel tooth meshes with the first bevel tooth. The first bevel tooth is connected to the first drive gear via the rotating shaft. The first bevel tooth is fixedly installed at one end of the rotating shaft. The first drive gear is fixedly sleeved on the rotating shaft.

[0013] Furthermore, receiving plates are provided on both sides of the conveying mechanism, and two receiving plates at the same height support the baking tray on the conveying mechanism that has reached the preset position.

[0014] Furthermore, the transmission mechanism includes a crossbeam, and a third motor, a second transmission chain, a third drive wheel, a third driven wheel, and several paddles mounted on the crossbeam. The third drive wheel and the third driven wheel are fixedly mounted at both ends of the crossbeam, with the third drive wheel mounted at the end closest to the third motor. The third drive wheel is connected to the third motor via a transmission connection. The second transmission chain is wound around the third drive wheel and the third driven wheel. Each paddle is fixedly mounted on the second transmission chain at intervals, so that the second transmission chain drives the paddles one by one to be transported to a predetermined position in the feeding device. After reaching the predetermined position, the paddles hold the baking tray and, through the rotation of the second transmission chain, move the baking tray to the end away from the feeding device.

[0015] Furthermore, each paddle is fixedly installed on the second conveyor chain at equal intervals. After two adjacent paddles reach the predetermined position, they are located on both sides of the lower end of the baking tray and simultaneously support the baking tray to steadily move the baking tray to the end away from the feeding device.

[0016] Furthermore, the paddle includes a bent portion and a main frame plate. The bent portion is obliquely fixedly mounted on the main frame plate and tilted towards the feeding device so that the paddle can enter directly below the baking pan and support the baking pan.

[0017] Furthermore, the tower unit includes a second motor, a second driving gear, a second driven gear, a third conveyor chain, and several tower plates. Each tower plate is fixedly installed on the third conveyor chain at intervals. The second motor is connected to the second driving gear to drive the second driving gear to rotate. The second driving gear and the second driven gear are connected through the third conveyor chain. The tower plates are used to reach the corresponding height position under the drive of the third conveyor chain to support the baking tray on the conveying mechanism, and continue to lower the baking tray from the conveying mechanism to the corresponding position under the drive of the third conveyor chain to complete the proofing operation of the food on the baking tray. After proofing is completed, the baking tray is lowered to the height position that the delivery device can support the baking tray, and then the delivery device outputs the baking tray.

[0018] Furthermore, each tower plate is fixedly installed at equal intervals on the third conveyor chain, so that the third conveyor chain lowers a row of baking trays on the conveying mechanism sequentially to the corresponding height through the tower plates.

[0019] Furthermore, each tower unit is equipped with a separate second motor, or several tower units share a second motor. The tower units sharing the same second motor are connected by a connecting shaft drive, so that the second motor can synchronously drive the third transmission chain on each tower unit.

[0020] Furthermore, it also includes a protective frame, on which a protective net is installed, and each tower unit is located within the protective net.

[0021] The second technical solution to achieve the objective of this invention is: a tower-style proofing method with multiple trays, comprising the following steps:

[0022] Step 1: The feeding device lifts the baking trays one by one to the corresponding height position until the baking trays can be supported by the conveying mechanism;

[0023] Step 2: The conveying mechanism moves the baking trays on the feeding device that have reached the corresponding height position to one end of the conveying mechanism's feeding device in sequence, until the baking trays form a whole row on the conveying mechanism.

[0024] Step 3: The tower unit supports a whole row of baking trays on the transmission mechanism and lowers the baking trays to the corresponding height position for proofing. The baking trays are lowered to the corresponding height position one row at a time in sequence for proofing, and the baking trays that have completed proofing are lowered to the height position that the delivery device can support.

[0025] Step 4: The feeding device holds the baking tray that has completed the proofing process and outputs it, thus completing the entire proofing process.

[0026] The beneficial effects of this invention are as follows: This invention employs a single-up, multi-down method to transfer the baking tray, which avoids vibration during tray transfer, improving the efficiency and safety of the proofing process. Furthermore, the single-action feeding device allows for pre-setting and control of the proofing time, improving the precision of the proofing operation. Attached Figure Description

Detailed Implementation

[0040] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0041] like Figures 1-12 As shown, a multi-tray tower-type proofing device includes a feeding device 1 and a proofing tower 2. The feeding device 1 is used to feed the baking trays containing the food to be proofed into the proofing tower 2. The proofing tower 2 is used to proof the food on the baking trays. The proofing tower 2 includes a conveying mechanism 6 and several tower units 5 connected in sequence. The conveying mechanism 6 passes through each tower unit 5 and is fixedly installed on the tower unit 5. One end of the conveying mechanism 6 extends into the feeding device 1 to receive the baking trays conveyed by the feeding device 1 and arrange the baking trays in sequence on the conveying mechanism 6. The tower unit 5 is used to receive the baking trays on the conveying mechanism 6 and lower the baking trays to the corresponding height before conveying them out, completing the proofing operation.

[0042] The feeding device 1 includes a frame 102 and a conveying mechanism 103, and a first motor 101, a receiving plate 104, a first driving gear 105, a first conveying chain 106, a first driven gear 107, a first bevel gear 108, a drive shaft 109, and a second bevel gear 110 mounted on the frame 102. The output shaft of the first motor 101 is connected to the drive shaft 109. The second bevel gear 110 is fixedly sleeved on the drive shaft 109. The second bevel gear 110 meshes with the first bevel gear 108. The first bevel gear 108 is connected to the first driving gear 105 via a rotating shaft. The first bevel gear 108 is fixedly mounted on the rotating shaft. At one end, a first driving gear 105 is fixedly sleeved on a rotating shaft. The first driving gear 105 is connected to a first driven gear 107 via a first transmission chain 106. Both ends of the first transmission chain 106 are sleeved on the first driving gear 105 and the first driven gear 107. A receiving plate 104 is linked to the first transmission chain 106. Each receiving plate 104 is fixedly installed on the first transmission chain 106 at equal intervals. Multiple first transmission chains 106 are arranged on opposite sides of the frame 102. Two receiving plates 104 at the same height on the first transmission chains 106 on both sides can just support one baking tray. The conveying mechanism 103 is located inside the frame 102 and close to the lower end of the first transmission chain 106. Receiving plates 104 are arranged on both sides of the conveying mechanism 103. The conveying mechanism 103 is a conveying device based on a conveyor belt, and the baking tray can be directly placed on the conveyor belt to achieve displacement.

[0043] The conveying mechanism 103 feeds the baking trays from the production line into the frame 102 and positions them at the bottom of the first conveying chain 106. When the baking trays reach the predetermined position, the receiving plates 104 located on both sides of the conveying mechanism 103 support the baking trays. The first motor 101 drives the rotating shaft to rotate, and then drives the first drive gear 105 to rotate through the meshing first bevel teeth 108 and second bevel teeth 110, thereby driving the first conveying chain 106 to rotate in the vertical direction. The first conveying chain 106 drives each receiving plate 104 to transmit power from bottom to top, thereby raising or lowering the baking trays in the vertical direction to the predetermined height position.

[0044] The transmission mechanism 6 includes a crossbeam 62, and a third motor 65, a second transmission chain 63, a third drive wheel (not shown), a third driven wheel 64, and several paddles 61 mounted on the crossbeam 62. The third drive wheel and the third driven wheel 64 are fixedly mounted at both ends of the crossbeam 62, with the third drive wheel mounted at the end closest to the third motor 65. The third drive wheel is connected to the third motor 65 in a transmission connection, so that the third motor 65 can drive the third drive wheel to rotate, thereby driving the second transmission chain 63 to rotate. The second conveyor chain 63 is wound around the third driving wheel and the third driven wheel 64. Each paddle 61 is fixedly installed on the second conveyor chain 63 at intervals, so that the second conveyor chain 63 drives the paddles 61 one by one to convey them to the predetermined position of the feeding device 1. When two adjacent paddles 61 reach the predetermined position of the feeding device 1, they are located just below the baking tray and in contact with the baking tray, thus supporting the baking tray. Under the driving action of the second conveyor chain continuing to rotate, the two paddles 61 are located on both sides of the lower end of the baking tray to support the baking tray more stably, and the baking tray from the feeding device 1 is transferred to the conveying mechanism 6, thereby conveying the baking tray into the proofing tower 2.

[0045] The second conveyor chain 63 rotates counterclockwise, thereby conveying each paddle 61 from below the baking pan to directly below the baking pan and into contact with the baking pan. After contact with the baking pan, the baking pan is then conveyed out together.

[0046] The paddle 61 includes a bent portion 611 and a main frame plate 612. The bent portion 611 is fixedly installed on the main frame plate 612. The bent portion 611 and the main frame plate 612 are an integral structure. The bent portion 611 is fixedly installed on the main frame plate 612 at an angle and is inclined toward the feeding device 1 so that the paddle 61 can better enter directly below the baking tray and support the baking tray.

[0047] The tower unit 5 includes a second motor 52, a second driving gear 53, a second driven gear 54, a third transmission chain, and several tower plates 51. Each tower plate 51 is fixedly mounted at equal intervals on the third transmission chain, and both sides of the third transmission chain are covered with tower plates 51. The second motor 52 is connected to the second driving gear 53 to drive the second driving gear 53 to rotate. The second driving gear 53 and the second driven gear are connected through the third transmission chain, thereby enabling the second motor 52 to drive the third transmission chain to rotate, which in turn drives the third transmission chain. The tray 51 on the third conveyor chain rotates, so that the tray 51 on the third conveyor chain reaches the corresponding height and is located directly below the baking tray on the conveying mechanism 6, supporting the baking tray. The third conveyor chain then rotates, thereby transferring the baking tray from the conveying mechanism 6 to the lever 61 on the tower unit 5, so that the food on the baking tray can be proofed on the tower unit 5. After proofing is completed, the third conveyor chain rotates again, thereby lowering the baking tray supported by the tray 51 to a certain height, where it is supported by the delivery device (not shown in the figure) and transported out, completing the proofing operation.

[0048] Each tower unit 5 can be equipped with a second motor 52, or several tower units 5 can share a second motor 52. For example, three tower units 5 can share a second motor 52. The tower units 5 that share the same second motor 52 are connected by a connecting shaft 7, so that the third conveyor chain on each tower unit 5 can be driven synchronously to simultaneously lift and lower the baking tray on the transmission mechanism 6 to each tower unit 5.

[0049] In an optional embodiment, a protective frame 4 is also included, on which a protective net 3 is installed. Each tower unit 5 is located within the protective net 3, thereby protecting the awakening tower 2, i.e., the transmission mechanism 6 inside the awakening tower 2, and preventing people from accidentally touching the screen or falling onto the tower unit 5, thus ensuring personnel safety.

[0050] In actual use, the conveying mechanism 103 of the feeding device 1 sequentially feeds the baking trays (e.g., baking trays from the production line) one by one into the predetermined position at the bottom of the frame 102. The baking trays are then supported by the receiving plates 104 on both sides of the conveying mechanism 103. The first motor 101 drives the baking trays vertically to the corresponding height position via the first conveying chain 106. The lever 61 on the transmission mechanism 6 supports the baking trays, and the third motor 65 moves the baking trays to the end of the transmission mechanism 6 away from the feeding device 1 via the second conveying chain 63. As the feeding device 1 continuously feeds the baking trays into the transmission mechanism 6, the transmission mechanism 6 moves the baking trays one by one into the transmission mechanism 6 via the lever 61, and they are supported by the tower plates 51 on the tower unit 5, until a row of baking trays is filled horizontally in the transmission mechanism 6. Once all the horizontal levers 61 at the top of the transmission mechanism 6 have supported the baking trays, forming a row of trays, the second motor 52 on the tower unit 5 drives the tower plate 51 to rotate via the third conveyor chain. The baking trays descend along with the supported tower plates 51, lowering the entire row of trays to the same height. Subsequent feeding of baking trays follows a similar process, creating rows of trays at different heights on the tower unit 5 for proofing. After proofing is complete, the third conveyor chain rotates again, lowering the tower plates 51 to their lowest position, where they are output by the delivery device below the tower, completing the entire proofing process.

[0051] In this proofing process, a single-on-multiple-down proofing operation of the baking trays can be achieved. That is, a single baking tray rises sequentially and is conveyed to the conveyor mechanism 6, while multiple trays simultaneously descend from the conveyor mechanism 6 and are output by the delivery device. This prevents vibration caused by only one tray being conveyed at a time when it is transferred from the conveyor mechanism 6 to the tray 51, thus avoiding disruption to the proofing process. When a row of neatly arranged baking trays is simultaneously fed into the tray 51, vibration is significantly reduced. Furthermore, the use of an independent feeding device 1 allows for control over the time taken to transfer the baking trays to the tray 51, enabling precise control over proofing time.

[0052] The embodiments disclosed in this specification are merely illustrative of one aspect of the invention, and the scope of protection of the invention is not limited to these embodiments. Any other functionally equivalent embodiments fall within the scope of protection of the invention. Those skilled in the art can make various other corresponding changes and modifications based on the technical solutions and concepts described above, and all such changes and modifications should fall within the scope of protection of the claims of this invention.
