Description

[Technical Field]

[0001] This invention relates to the field of bread production technology, specifically to a highly automated egg-crust bread production line and egg-crust bread production process. [Background Technology]

[0002] In the food industry, bread is a staple food consumed in large quantities daily. To meet people's increasing demands for taste and nutrition in bread, bread manufacturers are constantly developing new varieties to adapt to market needs. Egg-crust bread is one such popular type, with consumption increasing year by year. Egg-crust bread consists of bread slices and an egg crust. Currently, all bread manufacturers use manual wrapping for the egg crust. This manual production method increases labor costs and reduces production efficiency. Furthermore, the large number of workers involved in the labor-intensive process increases the risk of contamination in food production. Inconsistent egg crust wrapping due to varying levels of operator skill also affects product quality and appearance.

[0003] Appendix Figure 10 The egg-crust bread production line used by the applicant in its early stages has the following technical problems: bread slices 102 need to be manually taken to the receiving tray of the egg-crust machine 400 before being automatically packaged into egg-crust bread 101; the final formed egg-crust bread 103 needs to be manually taken to the existing packaging machine 600 for packaging into bags; after the filling machine of the existing bread machine 500 finishes injecting the filling, the bread slices are directly conveyed to the existing egg-crust machine 400, resulting in inconsistent conveying orientation of the bread slices and incompatibility between bread slices 102 and egg-crust bread 101. Therefore, the existing egg-crust bread production line has problems such as low production efficiency and the risk of secondary contamination. [Summary of the Invention]

[0014] On the other hand, a process for producing egg-crust bread using the aforementioned highly automated egg-crust bread production line includes the following steps:

[0015] Step 1: Eggshell production: The eggshell machine transports the produced eggshell sheets to the input end of the eggshell covering device. The eggshell cutting machine first cuts the eggshell sheets into strips, and then cuts the strips into blocks.

[0016] Step 2: Bread slice production: The slicer cuts the bread into slices, the unslicing machine cuts an opening in the side of each slice, and the sauce filling machine fills the opening with sauce.

[0020] The advantages of this invention are:

[0021] 1. The highly automated egg crust bread production line of the present invention realizes the fully automatic coating and packaging of egg crust and bread slices. The counting mechanism, receiving mechanism and bread slice conveying mechanism work together to deliver bread slices quantitatively and neatly to the egg crust. The flipping mechanism can evenly coat the egg crust onto the bread slices. Not only is the production efficiency high, but also the production process is free from human contact, reducing secondary contamination of the bread.

[0022] 2. By setting the apex of the second driven shaft lower than the apex of the drive shaft, the second driven shaft acts as a buffer when the formed egg crepe bread falls from the egg crepe conveyor belt, preventing the formed egg crepe bread from being subjected to excessively strong impact and falling apart, ensuring that the formed egg crepe bread lands intact on the packaging conveyor belt; by setting a drive motor to drive the first and second driven shafts to rotate simultaneously, not only is the egg crepe conveyed smoothly, but the output of the formed egg crepe bread is also guaranteed.

[0023] 3. The present invention sets the rotation speed of the second bread slice conveyor belt to be less than the rotation speed of the bread slice conveying mechanism, so that there is a speed difference between the second bread slice conveyor belt and the bread slice conveying mechanism. In this way, bread slices can be transferred from the second bread slice conveyor belt to the bread slice conveying mechanism in an orderly manner, and the bread slices entering the bread slice conveying mechanism have the same front-to-back spacing.

[0024] 4. The present invention includes a turning mechanism between the first bread slice conveyor belt and the second bread slice conveyor belt, so that after the bread slices enter the second bread slice conveyor belt, they are still conveyed forward along the short side, ensuring that the placement of the bread slices and egg crepes is compatible.

Detailed Implementation Methods

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Please see the appendix Figure 1-9 As shown, the present invention provides a highly automated egg crust bread production line, including an egg crust covering device 100, a bread slice feeding device 200, and a packaging device 300; the egg crust covering device 100 includes an egg crust conveying mechanism 1, which is provided with a counting mechanism 2, a receiving mechanism 3, and a turning mechanism 4 along the conveying direction of the egg crust 101; the counting mechanism 2 and the receiving mechanism 3 are mounted above the egg crust conveying mechanism 1, and the turning mechanism 4 is installed inside the egg crust conveying mechanism 1; the bread slice feeding device 200 includes a bread slice conveying mechanism 5 whose conveying direction is perpendicular to the egg crust conveying mechanism 1, which is mounted above the egg crust conveying mechanism 1 and located between the counting mechanism 2 and the receiving mechanism 3; the packaging device 300 is located at the output end of the egg crust conveying mechanism 1.

[0047] The highly automated egg crust bread production line of the present invention realizes the fully automatic wrapping and packaging of egg crust 101 and bread slice 102. The counting mechanism 2, receiving mechanism 3 and bread slice conveying mechanism 5 work together to deliver bread slice 102 quantitatively and neatly onto the egg crust. The flipping mechanism 4 can evenly wrap the egg crust 101 onto the bread slice 102. It not only has high production efficiency, but also has zero human contact during the production process, reducing secondary contamination of the bread.

[0048] Working principle: The egg crepe machine 94 is located at the input end of the egg crepe conveying mechanism 1. The produced egg crepe 101 enters the egg crepe conveying mechanism 1 and is conveyed from left to right, passing through the egg crepe cutting machine 95, the counting mechanism 2, the receiving mechanism 3, and the crepe-turning mechanism 4 in sequence, finally falling onto the conveyor belt of the packaging device 300. The bread slice supply device 200 conveys the sliced ​​bread slices 102 to the bread slice conveying mechanism 5. The counting mechanism 2 counts the bread slices 102 on the bread slice conveying mechanism 5. After reaching a specified number, the counting mechanism 2 pushes the bread slices 102 on the bread slice conveying mechanism 5 onto the receiving mechanism 3. Then, the receiving mechanism 3 drops the bread slices 102 vertically into the center of the egg crepe 101. The egg crepe and bread slices continue to be conveyed forward to the crepe-turning mechanism 4 for the egg crepe wrapping operation. Finally, the formed egg crepe bread 103 falls onto the packaging conveyor belt 6 and is packaged by the packaging machine.

[0049] In this invention, the bread slice conveying mechanism 5 is a common conveyor belt structure, which will not be described in detail here. A first vertical baffle 51 is provided at the end of the bread slice conveying mechanism 5 to prevent bread slices from falling off the end of the bread slice conveying mechanism 5.

[0050] In this invention, as shown in the appendix Figure 4 and 5 As shown, the eggshell conveying mechanism 1 includes a drive shaft 11, a first driven shaft 12, a second driven shaft 13, multiple eggshell conveyor belts 14, a transmission belt 15, and a drive motor 16. The first driven shaft 12 is located at the input end of the eggshell conveying mechanism 1, and the second driven shaft 13 is located at the output end of the eggshell conveying mechanism 1. The multiple eggshell conveyor belts 14 are wound side by side at intervals on the drive shaft 11 and the first driven shaft 12, with the distance between adjacent eggshell conveyor belts 14 being the same. The transmission belt 15 is wound on the drive shaft 11 and the second driven shaft 13, with the vertex of the second driven shaft 13 being lower than the vertex of the drive shaft 11. The output end of the drive motor 16 is connected to the drive shaft 11, and the drive motor 16 drives the drive shaft 11 to rotate, thereby driving the multiple eggshell conveyor belts 14 to rotate, and simultaneously driving the second driven shaft 13 to rotate. By setting the apex of the second driven shaft 13 lower than the apex of the drive shaft 11, the second driven shaft 13 acts as a buffer when the formed egg crepe bread falls from the egg crepe conveyor belt 14, preventing the formed egg crepe bread from being subjected to excessively strong impact and falling apart, ensuring that the formed egg crepe bread lands intact on the packaging conveyor belt 6. By setting a drive motor 16 to drive the first driven shaft 12 and the second driven shaft 13 to rotate simultaneously, not only is the smooth conveying of the egg crepe achieved, but also the smooth output of the formed egg crepe bread.

[0051] In this invention, the drive shaft 11 and the first driven shaft 12 have the same diameter and are on the same horizontal plane, allowing the eggshell to be transported horizontally along the eggshell conveyor belt 14. For every one revolution of the drive shaft 11, the second driven shaft 13 rotates three times, and the rotation ratio of the drive shaft 11 to the second driven shaft 13 is 1:3.

[0052] In this invention, as shown in the appendix Figure 6 and 7 As shown, the counting mechanism 2 includes a first support frame 21, a photoelectric sensor 22, a first driver 23, and a pusher plate 24. The photoelectric sensor 22 is mounted on the first support frame 21 and faces the bread slice conveying mechanism 5. The first driver 23 is fixedly mounted on the first support frame 21. The pusher plate 24 is connected to the output shaft of the first driver 23 and faces the bread slice conveying mechanism 5. The first support frame 21 includes a first support column and a second support column respectively disposed on both sides of the egg skin conveying mechanism 1, and a first support plate. The two ends of the first support plate are fixedly connected to the upper ends of the first support column and the second support column respectively. The photoelectric sensor 22 is mounted on the first support plate and counts the bread slices. When the count reaches the required number, the first driver 23 drives the pusher plate 24 to push the bread slices onto the receiving mechanism 3. The bread slice conveying mechanism 5 and the counting mechanism 2 realize the orderly arrangement and counting of the bread slices. In coordination with the receiving mechanism 3, the bread slices automatically enter the egg skin conveying mechanism 1 for egg skin coating.

[0053] In this invention, as shown in the appendix Figure 6 and 7 As shown, the receiving mechanism 3 includes a second support frame 31, multiple receiving trays 32, and a second driver 34. A connecting plate 33 is fixedly connected to the output end of the second driver 34. The multiple receiving trays 32 are fixedly connected to the connecting plate 33 and are positioned facing the bread slice conveying mechanism 5. The second support frame 31 includes a third support column and a fourth support column respectively disposed on both sides of the egg crepe conveying mechanism 1, and a second support plate. The two ends of the second support plate are fixedly connected to the upper ends of the third and fourth support columns respectively. The second driver 34 is fixedly connected to the second support plate. When a bread slice falls and hits the connecting plate 33, the connecting plate 33 acts as a positioning and shaping element, causing the bread slice to fall neatly onto the receiving tray 32. Then, the second driver 34 drives the connecting plate 33 and the receiving tray 32 to quickly retract, causing the bread slice to fall vertically and neatly onto the egg crepe, at which point the bread slice is positioned exactly in the middle of the egg crepe. The bread slice receiving mechanism 3 achieves a neat arrangement of bread slices, ensuring that each bread slice falls onto the egg crepe in the same position, guaranteeing that each subsequent bread slice evenly covers the egg crepe.

[0054] In this invention, a plurality of receiving trays 32 are equidistantly spaced on the connecting plate 33. Thus, each receiving tray 32 receives a slice of bread.

[0055] In this invention, as shown in the appendix Figure 3 As shown, the egg-flipping mechanism 4 includes a first flipping component 41 that flips the egg crepe on one side of the bread slice, and a second flipping component 42 that flips the egg crepe on the other side of the bread slice. The first flipping component 41 flips the egg crepe located on the right side of the bread slice to cover the bread slice, and the second flipping component 42 flips the egg crepe located on the left side of the bread slice to cover the bread slice, thus achieving automatic egg crepe covering.

[0056] In this invention, as shown in the appendix Figure 8 and 9 As shown, the first flipping assembly 41 includes a third support frame 43, multiple first flipping components 44, and a third driver 45. A first flipping component 44 is provided between adjacent egg crepe conveyor belts 14, and the first flipping component 44 faces the output end of the egg crepe conveying mechanism 1. The third support frame 43 includes a first pillar and a second pillar located on both sides of the egg crepe conveying mechanism 1, and a first rotating rod 46 whose two ends are rotatably connected to the first pillar and the second pillar, respectively. The third driver 45 is fixed to the first pillar and its output end is connected to the first rotating rod 46. The output end of the third driver 45 is connected to the first rotating rod and drives the first rotating rod 46 to rotate. The first flipping component 44 is fixedly connected to the first rotating rod 46. The first flipping component 44 faces the output end of the egg crepe conveying mechanism 1, and the third driver 45 drives the first rotating rod 46 to rotate upwards, causing the egg crepe located on the right side of the bread slice to flip and cover the bread slice. When the first flipping component 44 is not in operation, the first rotating rod 46 is hidden below the surface of the egg crepe conveyor belt 14 to avoid interfering with the conveying of the egg crepe, allowing the egg crepe to be conveyed forward smoothly.

[0057] The first flipping component 44 includes a first horizontal plate 441, a first arc-shaped plate 442, and a second horizontal plate 443. The first horizontal plate 441 is fixedly connected to the first rotating rod 46, and one end of the first arc-shaped plate 442 is fixedly connected to the first horizontal plate 441, while the other end is fixedly connected to the second horizontal plate 443. Since there are multiple first flipping components 44 on the lower surface of an egg crepe, when the egg crepe needs to be flipped, the first rotating rod 46 rotates, causing the first flipping components 44 to rotate. Multiple second horizontal plates 443 abut against the lower surface of the egg crepe, ensuring that the egg crepe is flipped neatly. The first arc-shaped plate 442 is used to cooperate with the side of the bread slice, so that the egg crepe can be tightly attached to the bread slice. Furthermore, since the first rotating rod 46 is located below the surface of the transverse conveyor belt, the arrangement of the first horizontal plate 441 provides rotation space for the first arc-shaped plate 442.

[0058] In this invention, the second flipping assembly 42 includes a fourth support frame, a plurality of second flipping components, and a fourth driver; a second flipping component is provided between adjacent eggshell conveyor belts 14; the second flipping assembly 42 is positioned towards the input end of the eggshell conveying mechanism 1; the fourth support frame includes a third pillar and a fourth pillar located on both sides of the eggshell conveying mechanism 1, and a second rotating rod whose two ends are rotatably connected to the third pillar and the fourth pillar respectively; the fourth driver is fixed on the third pillar and its output end is connected to the second rotating rod. When the second flipping component is not in operation, the second rotating rod is hidden below the surface of the eggshell conveyor belt 14 to avoid interfering with the conveying of the eggshell, allowing the eggshell to be conveyed forward smoothly.

[0059] The second flipping component includes a third horizontal plate, a second arc-shaped plate, and a fourth horizontal plate. The third horizontal plate is fixedly connected to the second rotating rod, and one end of the second arc-shaped plate is fixedly connected to the third horizontal plate, while the other end is fixedly connected to the fourth horizontal plate. Since there are multiple second flipping components on the lower surface of an egg crepe, when the egg crepe needs to be flipped, the second rotating rod rotates, causing the second flipping components to rotate. The multiple third horizontal plates abut against the lower surface of the egg crepe, ensuring that the egg crepe is flipped neatly. The second arc-shaped plate is used to cooperate with the side of the bread slice, so that the egg crepe can be tightly attached to the bread slice. Furthermore, since the second rotating rod is located below the surface of the transverse conveyor belt, the arrangement of the second horizontal plate provides rotation space for the second arc-shaped plate.

[0060] In this invention, the orientations of the second flipping component and the first flipping component 44 are not fixed, but the orientation of the second flipping component is always opposite to that of the first flipping component 44, so as to flip the egg skin on both sides of the bread slice respectively. The first flipping component can be set towards the input end of the egg skin conveying mechanism 1, and the second flipping component can be set towards the output end of the egg skin conveying mechanism 1.

[0061] In this invention, as shown in the appendix Figure 3 and 4 As shown, an adjustment mechanism 7 for fine-tuning the position of the bread slice is also provided between the first dough-turning assembly 41 and the second dough-turning assembly 42.

[0062] In this invention, the adjustment mechanism 7 includes a fifth support frame 71, an adjustment plate 72, and a fifth driver 73. The fifth support frame 71 includes an adjustment shaft 74, and the adjustment plate 72 is mounted on the adjustment shaft 74 with its orientation opposite to that of the first dough-turning component 44. The fifth driver 73 drives the adjustment shaft 74 to rotate, thereby causing the adjustment plate 72 to rotate downwards to fine-tune the position of the bread slices. After the first dough-turning component 41 covers one side of the bread slice with egg skin, the adjustment plate 72 rotates downwards to fine-tune the position of each bread slice, making each bread slice more neatly arranged.

[0063] In this invention, as shown in the appendix Figure 3 and 4As shown, the second dough-flipping assembly 42 is also equipped with a compacting mechanism 8 for pressing the egg crepe onto the bread slice. After the second dough-flipping assembly 42 flips the egg crepe and wraps it over the bread slice, the compacting mechanism 8 presses down to make the egg crepe and bread slice adhere more tightly.

[0064] In this invention, the compaction mechanism 8 includes a compaction plate 81 and a sixth actuator 82. The sixth actuator 82 drives the compaction plate 81 to move downwards to compact the egg crepe bread. After the second flipping assembly 42 flips the egg crepe and wraps it over the bread slice, the compaction mechanism 8 presses down to make the wrapping of the egg crepe and bread slice more compact.

[0065] In this invention, as shown in the appendix Figure 4 As shown, the bread slice supply device 200 also includes a slicer, a slicer unslicing machine, a sauce injector, a first bread slice conveyor belt 91, a turning machine 92, and a second bread slice conveyor belt 93. The turning machine 92 is located between the first bread slice conveyor belt 91 and the second bread slice conveyor belt 93. The output end of the second bread slice conveyor belt 93 faces and is close to the input end of the bread slice conveying mechanism 5. The rotational speed of the second bread slice conveyor belt 93 is less than the rotational speed of the bread slice conveying mechanism 5. By setting the rotational speed of the second bread slice conveyor belt 93 to be less than the rotational speed of the bread slice conveying mechanism 5, a speed difference is created between the second bread slice conveyor belt 93 and the bread slice conveying mechanism 5. This allows bread slices to be transferred orderly from the second bread slice conveyor belt 93 to the bread slice conveying mechanism 5, with the bread slices entering the bread slice conveying mechanism 5 having the same front-to-back spacing.

[0066] The slicer cuts baked bread into slices, the unslicing machine cuts an opening in the side of each slice, and the sauce injector injects sauce and meat floss into the opening. Then, the first bread slice conveyor belt 91 transports the sauce-injected bread slices, and the turning mechanism 92 ensures that the bread slices maintain their direction after entering the second bread slice conveyor belt 93. The slicer, unslicing machine, and sauce injector are existing technologies, and their specific structures are not described in detail here.

[0067] Appendix Figure 10 In existing technology, sliced ​​bread is typically rectangular. On the first bread slice conveyor belt 91, the bread slice is conveyed with its short side forward. After entering the second bread slice conveyor belt 93, the conveying direction changes, causing it to be conveyed with its long side forward. This results in a mismatch between the placement of the bread slices and the placement of the egg crepes, leading to an excess of egg crepes on the left and right sides of the bread slice, while the top and bottom sides are not adequately covered. Therefore, as shown in the attached... Figure 4 As shown, a turning mechanism 92 is set between the first bread slice conveyor belt 91 and the second bread slice conveyor belt 93, so that after the bread slices enter the second bread slice conveyor belt 93, they are still conveyed forward along the short side, ensuring that the placement of the bread slices and egg skins is compatible.

[0068] In this invention, the first bread slice conveyor belt 91 and the egg skin conveyor mechanism 1 are arranged in parallel, which can reduce the floor space occupied by the egg skin bread production line. The first bread slice conveyor belt 91 and the second bread slice conveyor belt 93 are arranged perpendicularly. Combined with the turning machine 92, it can ensure that the conveying direction of the bread slices remains unchanged and the short side is still conveyed forward.

[0069] In this invention, as shown in the appendix Figure 3 As shown, the input end of the eggshell covering device 100 is also equipped with an eggshell machine 94 and an eggshell cutter 95. The eggshell cutter 95 includes a transverse cutting structure for cutting the eggshell into strips and a longitudinal cutting mechanism for cutting the strips into blocks. The output port of the eggshell machine 94 is at a higher level than the eggshell conveying mechanism 1, and an inclined transition plate is provided between the output port of the eggshell machine 94 and the input end of the eggshell conveying mechanism 1. The eggshell is produced and output from the output port, enters the eggshell conveying mechanism 1 along the transition plate, and multiple sets of transverse cutting structures cut the eggshell into strips, while the longitudinal cutting mechanism cuts the strips into blocks.

The packaging machine is prior art and will not be described in detail here.

[0071] This invention also provides a process for producing egg-crust bread, comprising the following steps:

[0072] Step 1: Eggshell production: Eggshell machine 94 transports the produced eggshell sheets to the input end of eggshell covering device 100. Eggshell cutting machine 95 first cuts the eggshell sheets into strips, and then cuts the strips into blocks.

[0073] Step 2: Bread slice production: The slicer cuts the bread into slices, the unslicing machine cuts an opening in the side of each slice, and the sauce filling machine fills the opening with sauce.

[0074] Step 3: Placing the bread slice and egg crepe: Place the bread slice in the very center of the egg crepe;

[0075] Step 4: Covering and shaping: The flipping mechanism 4 flips the egg skin on both sides of the bread slice and then covers it onto the bread slice;

[0076] Step 5: Packaging and shaping: Use packaging device 300 to package the shaped egg skin bread.

[0077] In step three, the counting mechanism 2 counts the bread slices in the bread slice conveying mechanism 5 and pushes the bread slices onto the receiving mechanism 3; the receiving mechanism 3 delivers the bread slices to the center of the block egg skin.

[0078] In step four, the egg crepes on both sides of the bread slice are flipped over and wrapped around the bread slice using the first flipping component 41 and the second flipping component 42.
