[0017] In summary, the present invention has the following beneficial effects:

[0018] The delivery rack is set on the floor above the dough conveyor. When in use, the material bags are placed on the conveying mechanism, and are transported one by one at intervals through the conveying mechanism. When the material bags enter the flattening mechanism, the flattening mechanism flattens the material bags so that the internal distribution materials such as vegetables are flattened, which is convenient for the suction cups of the subsequent process to absorb; then the material bags are sorted by the sorting delivery mechanism, that is, some material bags are transported one by one to the material receiving and conveying mechanism, and then the material bags are delivered one by one to the dough conveyed by the dough conveyor through the material receiving and conveying mechanism. In addition, the part that is not transported in time enters the reflux mechanism and flows back to the conveying mechanism through the reflux mechanism. In addition, the dough is made by the corresponding production equipment and transported to the dough conveyor one by one at intervals. After the material bags are delivered, they are packaged by the corresponding packaging equipment.

[0019] The feeding conveyor belt, vibrating spreader, elevator, accelerating conveyor belt and sorting conveyor belt are connected in sequence to realize the transportation of material bags. In addition, the vibrating spreader is used to realize the dispersed transportation of material bags. In addition, the corresponding convex blocks of the lifting conveyor belt are used to drive the material bags to be lifted to the accelerating conveyor belt one by one, so that the material bags are transported at intervals.

[0020] During use, when the material bag follows the accelerating conveyor belt or the sorting conveyor belt to move to the flattening roller position, the flattening roller and the corresponding accelerating conveyor belt or the sorting conveyor belt squeeze the over-bulged material bag to make the material bag flat, which is convenient for the material bag to enter the sorting and delivery mechanism position for sorting. After the industrial camera detects that the material bag has entered the position, the sorting robot absorbs the corresponding material bag and places the material bag on the material receiving and conveying mechanism, and then enters the dough conveyor through the material receiving and conveying mechanism.

[0021] When the sorting robot places the material bag on the delivery conveyor belt and separates the adjacent material bags through the partition plate, and the material bag follows the delivery conveyor belt into the material guide channel, the partition plate is used to prevent the material bag from falling quickly. When the material bag is discharged from the conveyor belt and slides from the material guide channel along the arc guide plate to the horizontal guide plate position; then the conveyor belt and the paddle plate are driven by the placement of a motor to rotate. When the paddle plate follows the movement of the driving conveyor belt, the material bag is moved synchronously and dropped onto the dough, thereby achieving accurate delivery of the material bag; in addition, the distance between two adjacent paddle plates is consistent with the distance between two adjacent partition plates, that is, when a material bag slides along the arc guide plate, the material bag is moved in time through the paddle plate.

[0022] The bottom boxes are conveyed to the slide position one by one through the bottom box conveying mechanism, and the bottom boxes are driven to move synchronously by assembling the conveyor chain and the lever. When the bottom box moves to just below the dough conveyor belt, the dough conveyed by the dough conveyor belt falls into the bottom box, thereby realizing the loading of the dough into the bottom box. The material package is then moved by the lever and falls onto the dough to complete the placement of the material package. After that, it enters the packaging machine for automatic packaging.

[0023] Several bottom boxes are stacked and placed vertically on the feeding rack. When the bottom boxes are conveyed one by one, the pushing shaft and the pushing column are driven to rotate synchronously through the driving structure, and the edge of the bottom box at the lowest position is stuck in the thread groove. When the pushing column rotates, the thread groove moves spirally and drives the bottom box to move downward. When the edge of the bottom box is separated from the thread groove, it falls to the assembly conveyor chain, so that the bottom boxes fall to the assembly conveyor chain one by one, and then are conveyed to the dough conveyor belt position through the assembly conveyor chain for the dough to be placed.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with illustrations and specific embodiments.

[0034] like Figures 1 to 8 As shown, the present invention provides an automatic dough cake conveying and material bag delivery device, comprising a dough cake conveyor for conveying dough cakes one by one, and a material bag delivery device for delivering the conveyed material bags one by one onto the upper surface of the dough cake.

[0035] The material bag delivery device includes a delivery rack 1 located above the dough conveyor, a conveying mechanism for receiving and delivering material bags, a flattening mechanism for flattening the material bags, a sorting delivery mechanism for sorting the material bags, a material receiving and conveying mechanism for delivering the material bags to the corresponding dough, and a reflux mechanism for receiving material bags that have not been sorted out by the sorting delivery mechanism and delivering the material bags to the conveying mechanism. In this embodiment, the delivery rack 1 is set on the upper floor of the dough conveyor. When in use, the material bags are placed on the conveying mechanism, and are transported one by one in intervals through the conveying mechanism. When the material bags enter the flattening mechanism position, the flattening mechanism flattens the material bags so that the materials such as vegetables inside the material bags are flattened, which is convenient for the suction cups of the subsequent process to absorb; then the material bags are sorted by the sorting delivery mechanism, that is, some of the material bags are transported one by one to the material receiving and conveying mechanism, and then the material bags are delivered one by one to the dough conveyed by the dough conveyor through the material receiving and conveying mechanism. In addition, the part that is not transported in time enters the reflux mechanism and flows back to the conveying mechanism through the reflux mechanism. In addition, after the dough is made by the corresponding production equipment and transported to the dough conveyor one by one, and after the material package is put into the dough, it is packaged by the corresponding packaging equipment.

[0036] The conveying mechanism includes a storage hopper 2 arranged on the delivery rack 1 and used to receive the material bags, a feeding conveyor belt 3 located directly below the storage hopper 2, a vibrating material spreader 4 for receiving the material bags conveyed by the feeding conveyor belt 3, an elevator 5 for realizing one-by-one and interval conveying of the material bags, an accelerating conveyor belt 6 for receiving the material bags conveyed by the elevator 5, and a sorting conveyor belt 7 for receiving the material bags conveyed by the accelerating conveyor belt 6 and conveying the material bags to the sorting delivery mechanism directly below; the elevator 5 is provided with a lifting conveyor belt 33, and the surface of the lifting conveyor belt 33 is provided with a number of protrusions 34 that contact the feeding bag and drive the material bag to move up. The feeding conveyor belt 3, the vibrating material spreader 4, the elevator 5, the accelerating conveyor belt 6, and the sorting conveyor belt 7 are connected in sequence to realize the conveying of the material bags, and the vibrating material spreader 4 is used to realize the dispersed conveying of the material bags, and the corresponding protrusions 34 of the lifting conveyor belt 33 are used to realize the lifting of the material bags to the accelerating conveyor belt 6 one by one, so as to achieve the interval conveying of the material bags.

[0037] In this embodiment, a partition plate 13 can be set in the storage hopper 2 to achieve the scattering of material bags in the storage hopper 2 in two directions, and the feeding conveyor belt 3, the vibrating spreader 4, the elevator 5, the acceleration conveyor belt 6, the sorting conveyor belt 7, the flattening mechanism, the sorting and delivery mechanism, the material receiving and conveying mechanism, and the dough conveyor are all arranged in two groups to achieve the simultaneous conveying of the corresponding scattered material bags.

[0038] The flattening mechanism can be arranged to be located directly above the accelerating conveyor belt 6 or directly above the sorting conveyor belt 7. The flattening mechanism includes a flattening frame 8 fixed to the delivery frame 1, a flattening roller 9 rotatably connected to the flattening frame 8, an elastic pad is arranged on the surface of the flattening roller 9, and the flattening roller 9 is arranged horizontally. A gap is left between the flattening roller 9 and the upper surface of the accelerating conveyor belt 6 or the sorting conveyor belt 7 for the flattened material bag to pass through. When the material bag follows the accelerating conveyor belt 6 or the sorting conveyor belt 7 to move to the flattening roller 9 position, the flattening roller 9 and the corresponding accelerating conveyor belt 6 or the sorting conveyor belt 7 squeeze the over-bulged material bag, so that the material bag is in a flat state, which is convenient for the material bag to enter the sorting delivery mechanism position for sorting.

[0039] The return mechanism includes a return conveyor belt 21 located below the sorting conveyor belt 7 and used to receive the material bags conveyed by the sorting conveyor belt 7, and a return elevator 22 used to convey the material bags on the return conveyor belt 21 to the storage hopper 2. When in use, the material bags on the sorting conveyor belt 7 that are taken away by the sorting robot 10 fall to the return conveyor belt 21, and move to the return elevator 22 along the return conveyor belt 21, and enter the storage hopper 2 again through the return elevator 22, so as to facilitate re-transportation.

[0040] The sorting and delivery mechanism includes a sorting rack 35, an industrial camera arranged on the sorting rack 35 and located directly above the sorting conveyor belt 7, a sorting robot 10 arranged on the delivery rack 1 and placing the material bag on the sorting conveyor belt 7 on the receiving conveying mechanism, a receiving component for receiving the material bag carried by the sorting robot, and a replenishing component arranged on the sorting rack 35 and used for replenishing the material bag to the receiving conveying mechanism, wherein the industrial camera is located on the sorting rack 35 near the material bag entry end, the sorting robot 10 can be provided with corresponding suction cups for sucking the material bags, the suction cups can be provided with three and can suck three material bags at the same time, and the sorting robot 10 is provided with one or two. The receiving assembly includes a receiving frame 36 fixed to the sorting frame 35, two receiving plates 37 connected to the delivery frame in a sliding manner to receive the material bags, and a servo motor 38 arranged on the sorting frame 35 to drive the two receiving plates 37 to move. The sliding direction of the receiving plates 37 is horizontal and perpendicular to the moving direction of the material bag sorting conveyor belt 7, and the length of the receiving plates 37 can receive two material bags at the same time. In this embodiment, the rotation axis of the output end of the servo motor 38 is vertically arranged, and a connecting rod 39 is arranged between each receiving plate 37 and the output end of the servo motor 38. The connecting rod 39 is horizontally arranged and the two ends are respectively hinged to the corresponding receiving plate 37 and the output end of the servo motor 38. After the output end of the servo motor 38 rotates a certain angle, the connecting rod 39 drives the two receiving plates 37 to move synchronously toward or in the opposite direction. In order to facilitate the material bag to fall from the receiving plate 37, the receiving plate 37 is provided with a plurality of stripping grooves 40, and the receiving frame 36 is provided with a plurality of gear rods 41 respectively penetrating the corresponding stripping grooves 40 and limiting the material bag to move synchronously with the receiving plate 37. After the receiving plate 37 moves in the opposite direction, the material bag falls between the two receiving plates 37 to the material receiving conveying mechanism and is conveyed by the material receiving conveying mechanism. The feeding assembly includes a feeding conveying belt 42 rotatably connected to the sorting frame 35, and a feeding motor 43 arranged on the sorting frame 35 and driving the feeding conveying belt 42 to rotate. The feeding conveying belt 42 is located directly above the material receiving conveying mechanism, and the material bag conveyed by the feeding conveying belt 42 falls to the material receiving conveying mechanism. When the material bag follows the sorting conveyor belt into the sorting and delivery mechanism, after the industrial camera detects the material bag entering the position, the sorting robot 10 absorbs the corresponding material bag and places the material bag on the receiving plate 37, and the sorting robot 10 can absorb two material bags at the same time and place them on the receiving plate 37. When it is necessary to put the material bag into the material receiving and conveying mechanism, the servo motor 38 drives the two receiving plates 37 to move in the opposite direction, so that the two material bags fall and the material bag is delivered; and when there is a missing material bag when the material receiving and conveying mechanism conveys the material bag, the replenishing motor 43 drives the replenishing conveyor belt 42 to transport the material bag to the missing position of the material receiving and conveying mechanism. After the replenishing conveyor belt 42 outputs the material bag, the sorting robot 10 can pick up the material bag and place it at the corresponding position of the replenishing conveyor belt 42 to complete the replenishment. The photoelectric sensor can also be used to sense the missing material bag of the replenishing conveyor belt 42, and the material bag can be replenished by the sorting robot 10.In addition, the material replenishing component is used to replenish the material receiving and conveying mechanism, so as to avoid the situation of empty packages at the corresponding positions in the material receiving and conveying mechanism, that is, the situation of no corresponding material packages, so as to reduce the empty package rate of the material receiving and conveying mechanism from about 2% to about 5 / 1000, thereby improving the qualified rate of the packaged products.

[0041] The receiving and conveying mechanism includes a material guide channel 11 connected to the sorting rack 35 and arranged vertically or obliquely, a delivery conveyor belt 12 arranged on the delivery rack 1 and used to convey the material bags output by the receiving component, and a partition plate 13 arranged on the delivery conveyor belt 12 to separate the material bags, and the material bags are divided into a plurality of chambers by the partition plate. The delivery conveyor belt 12 is arranged in an L shape, and a horizontal section of the delivery conveyor belt 12 is parallel to the sorting conveyor belt 7, and the delivery conveyor belt 12 is located directly below the receiving plate 37 and the feeding conveyor belt 42. A vertical section of the delivery conveyor belt 12 is arranged through the material guide channel 11, and the L-shaped bending position of the delivery conveyor belt 12 is arranged in an arc shape or a polygonal shape. The partition plate 13 is attached to the inner wall of the material guide channel 11 and keeps the material bags separated. The dough conveyor is provided with a placement component for receiving the conveyed material bags of the delivery conveyor belt 12 and placing the material bags on the dough surface. The placing component is arranged on the placing rack 14 of the dough conveyor, a horizontal guide plate 15 is arranged on the placing rack 14 and used to receive the material bag, an arc guide plate 16 is arranged on the placing rack 14 and supplies the material bag to move the horizontal guide plate 15 by the feeding conveyor belt 12, a driving conveyor belt 17 is rotatably connected to the placing rack 14 and is located directly above the horizontal guide plate 15, and a plurality of paddles 18 are evenly arranged on the driving conveyor belt 17 and paddle the material bag relative to the horizontal guide plate 15. The distance between two adjacent paddles 18 is consistent with the distance between two adjacent partition plates 13, and the horizontal guide plate 15 is provided with a paddle groove 20 for the paddle plate 18 to penetrate, and the length direction of the paddle groove 20 is parallel to the moving direction of the driving conveyor belt 17. The corresponding photoelectric sensor of the sorting rack 35 is used for sensing. When it is sensed that the chamber corresponding to the delivery conveyor belt for the material package to be delivered moves to just below the receiving plate 37, the receiving plate 37 opens and the material package falls into the corresponding chamber of the delivery conveyor belt 12, and the material package follows the delivery conveyor belt 12 into the material guide channel 11, and the partition plate 13 is used to prevent the material package from falling quickly; and after the delivery conveyor belt 12 receives the material package dropped from the receiving plate 37 and continues to move, the photoelectric sensor behind it can be used to detect again whether there is a material package in the chamber it has entered. When a material package is missing, the material package is transported to the chamber of the missing material package through the replenishing conveyor belt 42. When the material bag is discharged from the conveyor belt and slides from the material guide channel 11 along the arc guide plate 16 to the position of the horizontal guide plate 15; when the paddle plate 18 follows the movement of the driving conveyor belt 17, the material bag is moved synchronously and dropped onto the dough, so as to achieve accurate delivery of the material bag; in addition, the distance between two adjacent paddle plates 18 is consistent with the distance between two adjacent partition plates 13, that is, when a material bag slides along the arc guide plate 16, the material bag is moved in time through the paddle plate 18.

[0042] Many existing cakes are non-fried cakes. After the cakes are made, the process of transporting and conveying them out of the factory easily causes the cakes to scatter. The cakes need to be installed in the bottom box to prevent the cakes from scattering later. The edge of the bottom box is generally provided with a folded edge. The cake conveyor includes a conveyor frame 23, a cake conveyor belt 24 rotatably connected to the conveyor frame 23 and used to drive the cakes to move relative to the conveyor frame 23, an assembly conveyor chain 25 for conveying cakes and bottom boxes, and a bottom box conveying mechanism for conveying bottom boxes one by one to the assembly conveyor chain 25 and for the cakes to fall into the bottom box. The cake conveyor belt 24 is located directly above the cakes and is provided with a toggle block 44 for toggling the cakes to move. The conveyor frame 23 is provided with a driving motor for driving the assembly conveyor chain to rotate, and one of the driven shaft ends of the assembly conveyor chain 25 is connected to the driving shaft end of the dough conveyor belt 24 through a synchronous belt, and at the same time, one of the driven shaft ends of the assembly conveyor chain 25 is connected to the driving shaft end of the delivery conveyor belt 12 through a synchronous belt, and one of the driven shaft ends of the assembly conveyor chain 25 is connected to the driving shaft end of the driving conveyor belt 17 through a synchronous belt, so that when the assembly conveyor chain 25 moves, it drives the dough conveyor belt 24, the driving conveyor belt 17 and the delivery conveyor belt 12 to move synchronously at the same speed, thereby achieving that a material bag can be delivered in time for each dough moved.

[0043] The conveyor frame 23 is provided with a slide plate 26 for the bottom box to slide, and the slide plate 26 can also be set as a conveyor belt structure. Two slide plates 26 are set and are symmetrically arranged. The two slide plates 26 are both in contact with the lower surface of the dough. The assembly conveyor chain 25 is provided with a lever 27 for moving the bottom box. The lever 27 is passed between the two slide plates 26 and protrudes from the upper surface of the slide plate 26. The slide plate 26 is located below the dough conveyor belt 24. The dough conveyed by the dough conveyor belt 24 falls to the bottom box corresponding to the position of the slide plate 26; the material bag released by the material bag releasing device falls on the dough loaded in the bottom box. When in use, the bottom boxes are conveyed one by one to the position of the slide plate 26 through the bottom box conveying mechanism, and the bottom boxes are driven to move synchronously by assembling the conveying chain 25 and the lever 27. When the bottom box moves to just below the dough conveyor belt 24, the dough conveyed by the dough conveyor belt 24 falls into the bottom box, thereby realizing the loading of the dough into the bottom box. Then, the material package is moved by the lever plate 18 and falls onto the dough to complete the placement of the material package, and then enters the packaging machine for automatic packaging.

[0044] The assembly conveyor chain 25 extends to the bottom of the bottom box conveying mechanism, that is, the assembly conveyor chain 25 moves from the bottom of the bottom box conveying mechanism to the bottom of the output end of the dough conveyor belt 24, and then moves to the position of the corresponding dough packaging mechanism. The bottom box conveying mechanism includes a bottom box feeding rack 28 arranged on the conveyor frame 23 and for the bottom boxes to be stacked vertically, and a bottom box pushing assembly that pushes the bottom boxes one by one. The bottom box pushing assembly removes the bottom box at the bottom of the bottom box feeding rack 28 and drops it to the position of the assembly conveyor chain 25 and is driven by the assembly conveyor chain 25. The bottom box pushing assembly includes a plurality of vertically arranged pushing shafts 29 arranged on both sides of the bottom box feeding rack 28, a pushing column 30 arranged on the pushing shaft 29, a threaded groove 31 opened on the side wall of the pushing column 30 and for the bottom box edge to be stuck, and a driving structure 32 arranged on the feeding rack and driving a plurality of pushing racks to rotate synchronously. The driving structure 32 can be a driving motor, and the driving motor is synchronously connected to a plurality of pushing shafts 29. When in use, several bottom boxes are stacked and placed vertically on the feeding rack 28. When the bottom boxes are conveyed one by one, the pushing shaft 29 and the pushing column 30 are driven to rotate synchronously through the driving structure 32, and the edge of the bottom box located at the lowest position is stuck in the thread groove 31. When the pushing column 30 rotates, the thread groove 31 moves spirally and drives the bottom box to move downward. When the edge of the bottom box disengages from the thread groove 31, it falls to the assembly conveyor chain 25, so that the bottom boxes fall to the assembly conveyor chain 25 one by one, and then are conveyed to the position of the dough conveyor belt 24 through the assembly conveyor chain 25 for the dough to be placed.
