[0001] The present invention relates to the field of food processing equipment, and in particular to a double-layer automatic stacking device applied to a cake processing production line. Background Art

[0002] At present, food processing machinery mainly develops towards the directions of production automation, high utilization rate of raw materials, energy conservation of mechanical equipment, food safety, and generalization of mechanical equipment. During the production process of pocket cakes, steps such as whipping and stirring, injecting slurry, baking in a tunnel oven, spraying oil, cooling, belt conveying, cutting into strips, flipping, laminating, forming and separating, ultraviolet sterilization, and packaging are required. Among them, the flipping and laminating steps are mostly realized manually in the existing technological processes. Specifically, the whole piece of cake baked by the tunnel oven is laid flat on the conveyor belt for conveying, and then cut into strips by a cake cutting device. After that, a part of the strip-shaped cake is manually flipped so that the burnt layer faces downwards, and then laminated, so that the burnt layers of the two overlapping cakes face the upper and lower surfaces respectively. The production efficiency of this operation method is relatively low. Summary of the Invention

[0008] As a further improvement, the turning mechanism further includes a baffle plate configured for each turning plate. The baffle plate is fixed to the turning frame and is located at one end of the turning end of the turning plate. There is a gap between the baffle plate and the turning plate, and the spiral arc of the baffle plate is consistent with the spiral arc of the turning plate.

[0009] As a further improvement, the turning mechanism further includes an adjusting block and an adjusting bolt.

[0030] The following describes the specific embodiments of the present invention with reference to the accompanying drawings.

[0031] As shown in the attached Figure 1 、 10 and 11, a double-layer automatic stacking device applied to a cake processing line includes an upper conveyor 2, a lower conveyor 1, a turning mechanism 3 and a guiding mechanism 4. The upper conveyor 2 and the turning mechanism 3 are respectively fixed on both sides in the width direction of the lower conveyor 1, and the upper conveyor 2 is located above the conveying plane of the lower conveyor 1.

[0032] As shown in the attached Figure 1 and 2 shown, gantry frames 22 are fixed at both the front and rear ends in the conveying direction of the upper conveyor 2 on the lower conveyor 1. Specifically, the gantry frames 22 straddle the conveying plane of the lower conveyor 1, and both sides of the gantry frames 22 are fixed on the main beams on both sides of the lower conveyor 1. Transverse adjusting plates 23 are fixed at positions corresponding to both sides of the upper conveyor 2 on the gantry frames 22, and strip-shaped holes 27 are provided on the transverse adjusting plates 23 in the same direction as the width direction of the lower conveyor 1. Longitudinal adjusting plates 24 are fixed at positions corresponding to each of the transverse adjusting plates 23 on the upper conveyor 2, and strip-shaped holes 27 are provided on the longitudinal adjusting plates 24 in the same direction as the conveying direction of the lower conveyor 1. Fixing screws 25 are inserted through the strip-shaped holes 27 between the upper and lower corresponding transverse adjusting plates 23 and longitudinal adjusting plates 24, and fixing nuts 26 are screwed at the upper and lower ends of the transverse adjusting plates 23 and the upper and lower ends of the longitudinal adjusting plates 24. Through the fixed connection of the fixing nuts 26, the upper and lower ends of each fixing screw 25 are respectively fixedly connected to the transverse adjusting plates 23 and the longitudinal adjusting plates 24, so as to realize the upper conveyor 2 being suspended and fixed under the gantry frames 22, so that there is a certain gap between the conveying planes of the upper conveyor 2 and the lower conveyor 1. In addition, by moving the fixing screws 25 along the length direction of the strip-shaped holes 27, the lateral and longitudinal position adjustments of the upper conveyor 2 relative to the lower conveyor 1 can also be realized.

[0033] As shown in the attached Figures 4 to 9 figure, the turning mechanism 3 includes a turning frame fixed to the lower conveyor 1, a plurality of turning plates 31 connected to the turning frame, and a baffle 32 configured for each turning plate 31. Both the turning plate 31 and the baffle 32 are spiral-shaped plates. The axis of the spiral of the turning plate 31 is inclined relative to the conveying direction of the upper conveyor 2 and is inclined towards the end of the upper conveyor 2. That is, this inclined structure when viewed from above the turning plate enables the cake after turning to be conveyed towards the end of the upper conveyor 2 under the guiding action of the turning plate 31, so as to overlap with the cake conveyed on the upper conveyor 2. One end of the turning plate 31 is a transition end 312 and the other end is a turning end 313. The transition end 312 faces the starting end of the lower conveyor 1, and the transition end 313 is horizontally close to the conveying plane of the lower conveyor 1. When the cake 7 is conveyed on the conveying plane of the lower conveyor 1, the transition end 312 being close to the conveying plane of the lower conveyor 1 enables the cake 7 to transition along the transition end to the spiral plate of the turning plate 31, and the cake 7 moves along the spiral plate for turning during the movement, so that the burnt layer 71 on the upper surface of the cake 7 is turned downward.

[0034] Furthermore, the upper side of the turning end 313 is inclined towards the side of the upper conveyor 2, and the included angle formed by the turning end 313 and the transition end 312 when viewed frontally is less than 90°. Specifically, it is the angle a as shown in the attached Figure 8 figure. This structure with an inclination less than 90° can be equivalent to restricting the tilting direction of the strip-shaped cake 7 after turning. That is, the strip-shaped cake 7 is horizontally conveyed on the lower conveyor 1 and then tilted towards the side of the upper conveyor 2 after turning to the turning end, so that the side of the cake 7 facing downward when being conveyed at the starting end of the lower conveyor 1 is turned upward, realizing the turning of the burnt layer 71 of the cake 7 downward. Additionally, as shown in the attached Figure 5 figure, the baffle 32 is fixed to the turning frame 31 and is located at one end of the turning end 313 of the turning plate 31, and there is a gap between the baffle 32 and the turning plate 31. This gap is the gap for the strip-shaped cake 7 to move and turn on the turning plate 31. At the same time, the spiral arc of the baffle 32 is consistent with the spiral arc of the turning plate 31. When the cake 7 moves and tilts for turning on the turning plate 31, the structure of this baffle 32 can play a role in supporting the cake 7, preventing the cake 7 from sliding directly off the turning plate 31 without turning along the spiral surface of the turning plate 31 during the movement on the turning plate 31.

[0035] As shown in the attached Figures 4 to 6As shown in the figure, the turning frame includes a column 33, a cross beam 34 and a fixing block 35. Both ends of the fixing block 35 are provided with connection holes 351. Threaded holes 352 penetrating to the outside of the fixing block 35 are provided on the sides of the two connection holes 351. Fixing bolts 36 are screwed into the connection holes 351 from the threaded holes 352. The columns 33 are fixed on both sides of the lower conveyor 1, and the two columns 33 are both connected with the fixing block 35. During installation and fixation, pass the two columns 33 through one of the connection holes 351 of the fixing block 35, then pass the two ends of the cross beam 34 through the other connection holes 351 of the fixing blocks 35 connecting the two columns 33 respectively. After that, screw the fixing bolts 36 from the threaded holes 352 into the connection holes until they are tightened against the column 33 or the cross beam 34, so as to realize the fixed connection between the column 33 and the cross beam 34, and make the two columns 33 and the cross beam 34 form a structure consistent with the above-mentioned gantry 22. And by adjusting the positions of the column 33 and the cross beam 34 relative to the connection holes 351 of the fixing block 35, the height adjustment or the lateral position adjustment of the cross beam 34 relative to the conveying plane of the lower conveyor 1 can be realized.

[0036] Continue to refer to the appendix Figures 4 to 6 As shown in the figure, the turning mechanism 3 further includes an adjusting block 37 and an adjusting bolt 38, and the turning plate 31 and the baffle 32 are respectively connected to the cross beam 34 through an adjusting block 37. The structure of the adjusting block 37 is the same as that of the above-mentioned fixing block 35, that is, both ends of the adjusting block 37 are also provided with connection holes 351. Threaded holes 352 penetrating to the outside of the adjusting block 351 are provided in the two connection holes 351. The adjusting bolts 38 are screwed into the connection holes 351 from the threaded holes 352, and the adjusting bolts 38 are the same as the fixing bolts 36. Vertical adjusting rods 311 are fixed on the turning plate 31 and the baffle 32. During installation, pass one of the connection holes 351 of each adjusting block 37 through the cross beam 34 of the turning frame, and then pass each adjusting rod 311 through the other connection hole 351 of an adjusting block 37 respectively; after that, screw the adjusting bolts 38 from the threaded holes 3522 of the adjusting block 37 into the connection holes 351 until they are tightened against the adjusting rod 311, so as to realize the fixed connection between the turning plate 31 and the baffle 32. And by adjusting the positions of the adjusting block 37 relative to the cross beam 34 and the adjusting rod 311, the height adjustment of the turning plate 31 or the baffle 32 relative to the conveying plane of the lower conveyor 1, the lateral position adjustment relative to the upper conveyor 2, and the adjustment of the tilting angle of the swing relative to the upper conveyor 2 can be realized. Through this multi-dimensional adjustment, the turning mechanism 3 can be more suitable for the conveying of cakes 7 of more different size types.

[0037] As shown in the appendix Figure 1 and 3As shown, the guiding mechanism 4 includes a guiding plate 41, a guiding frame 43, an adjusting block 45, and an adjusting bolt 44. The guiding mechanisms are fixed at the starting end of the conveying of the upper conveyor 2 and at the position of the lower conveyor 1 near the end of the upper conveyor 2. Specifically, the guiding plates 41 are fixed on both sides of the starting end of the upper conveyor 2 in the conveying plane. The guiding plates 41 are also fixed on both sides of the lower conveyor 1 at the position near the end of the upper conveyor 2 and on both sides of the upper conveyor 2, and the guiding plates 41 are close to the conveying plane of the lower conveyor 1. Through the structure of the guiding plates 41, the cake 7 can move along the gap between the two guiding plates 41 to avoid skewing. The structure of the guiding frame 43 is the same as that of the gantry formed by the vertical column 33 and the cross beam 34 of the turning mechanism 3, and the guiding frame 43 is fixed to the main beams on both sides of the upper conveyor 2 or the main beams on both sides of the lower conveyor 1. Further, the fixing structures described in this embodiment can all be realized by welding or screwing bolts for locking to achieve fixed connection. The structure of the adjusting block 45 is the same as that of the fixing block 35 and the adjusting block 37, that is, connection holes 351 are provided at both ends of the adjusting block 45, the axis lines of the two connection holes 351 are perpendicular to each other, and threaded holes 352 penetrating to the outside of the adjusting block 45 are provided in both connection holes 351. The adjusting bolts 44 are screwed into the connection holes 351 from the threaded holes 352 of the adjusting block 45. In addition, vertical guiding rods 42 are fixed on the guiding plates 41. When installing the guiding plates 41, one of the connection holes 351 of each adjusting block 45 is passed through the cross beam of the guiding frame 43, and then each connecting rod 42 is respectively passed through the other connection hole 351 of an adjusting block 45. Then, the adjusting bolts 44 are screwed into the connection holes 351 from the threaded holes 352 of the adjusting block 45 until they are tightened against the guiding rods 42, and the fixed connection of the guiding plates 41 can be achieved. Moreover, by adjusting the position of the adjusting block 45 relative to the cross beam of the guiding frame 43 and the guiding rods 42, the height adjustment and the lateral position adjustment of the guiding plates 41 relative to the conveying plane of the lower conveyor 1 or the conveying plane of the upper conveyor 2 can be realized. Through this multi-dimensional adjustment method, the guiding plates 41 can be more suitable for guiding and limiting cakes 7 of more different size types.

[0038] In addition, as a preferred embodiment of this embodiment, as shown in the attached Figure 10 、 14As shown in FIGS. 14 and 15, a cake strip cutter 5 is fixedly connected to the starting end of the lower conveyor in the conveying direction, and a cake block cutter 6 is fixedly connected to the ending end of the lower conveyor in the conveying direction. The cake strip cutter 5 includes a cutter roller 51 and a plurality of blades 52 spacedly arranged on the cutter roller 51. The cutter roller 51 is horizontally arranged at the starting end of the lower conveyor 1, and the cutter roller 51 is driven to rotate by a motor (not shown in the figure). The cake block cutter 6 includes a tool holder 61 and a cutter 62 located inside the tool holder 61. Vertical guide rails 63 are provided on both sides of the tool holder 61. The two sides of the cutter 62 are inserted into the guide rails 63 to limit the cutter 62 to move only up and down. At the same time, the cake block cutter 6 may further include a power mechanism for driving the cutter 62 to move up and down. This power mechanism can be a cylinder or a crank - connecting rod mechanism 64 driven by a motor, so as to realize the reciprocating movement of driving the cutter 62 vertically up and down.

[0039] After the cake 7 is conveyed out by a baking conveyor line (not shown in the figure), it can be conveyed onto the lower conveyor 1. After baking, the cake 7 is in the form of a whole piece flatly covering the conveying plane. Therefore, when the cake flatly laid on the conveying plane of the lower conveyor 1 is conveyed to the cake strip cutter 5, the blades 52 on the rotating cutter roller 51 can cut the whole cake into several strip - shaped cakes 7. And half of them are conveyed on one side of the lower conveyor 1, that is, on the upper conveyor 2, and the other half is conveyed to the turning mechanism 3. That is, the other half of the strip - shaped cakes 7 are respectively conveyed onto each turning plate for turning over. This process is as shown in the appendix Figures 10 to 12 As shown; after turning over, the strip - shaped cakes 7 are inclined and conveyed towards the ending end of the upper conveyor 2. And when they are conveyed to the ending end of the upper conveyor 2, they overlap with the strip - shaped cakes 7 conveyed on the upper conveyor 2. This process is as shown in the appendix Figure 11 and 13 As shown; the overlapped strip - shaped cakes 7 move between the two guide plates 41 of the guiding mechanism 4 under the conveyance of the lower conveyor 1. Through the limitation of the two guide plates 41, the upper - layer strip - shaped cakes 7 and the lower - layer strip - shaped cakes 7 are aligned one by one; the overlapped and aligned strip - shaped cakes 7 continue to move under the conveyance of the lower conveyor 1. When they move to the cake block cutter 6, they are horizontally cut by the cutter 62 of the cake block cutter, and finally two cakes overlapped up and down are formed. Thus, it can be seen that the present invention can automatically turn over the strip - shaped cakes 7 and automatically stack them, which is more efficient than the manual operation method, and can save a large amount of labor costs, which is beneficial to the production of enterprises.

[0040] The above is only the specific embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any non - substantial modification made to the present invention using this concept shall fall within the scope of infringement of the protection of the present invention.
