Technical Field

[0002] In the cookie production process, after baking and cooling, the cookies need to be placed in paper trays before being packaged into cookie jars. Neatly arranging a certain number of loose cookies in paper trays prevents them from breaking during transportation. Furthermore, placing multiple paper trays containing cookies into cookie jars enhances the product's appearance and perceived quality.

[0003] The current cookie-packing process typically involves the cookies being conveyed through a system after baking, and then manually or using a simple cookie-packing mechanism. However, with increasing market demand, customers are also requiring faster production speeds, making manual cookie packing insufficient.

[0004] Because the cookies move dynamically on the conveyor system, the existing paper tray dropping mechanism has difficulty simultaneously handling the feeding of empty paper trays and the dropping of cookies in continuous production, resulting in low production efficiency.

[0016] Beneficial effects: 1. During production, the finished product conveyor line operates intermittently. The first suction unit is connected to an external fan, which uses negative pressure to suction several empty paper trays from the second output end. The trays are then moved above the input end and released, leaving them on the input end. The first suction unit then returns to above the second output end, ready for the next suction cycle.

[0017] When the first suction unit moves above the input end of the finished product conveyor line, the cookie-picking cavity mechanism is activated. The cookie-picking cavity mechanism and the paper tray picking cavity mechanism move at the same speed. When the first suction unit descends and places the paper tray, the second suction unit descends simultaneously, picking up several cookies from the first output end. When the first suction unit rises and returns to the right, the second suction unit, carrying multiple cookies, moves synchronously from left to right above the input end. When the first suction unit descends again to perform the next paper tray picking action, the second suction unit descends synchronously, causing multiple cookies to fall one by one into the corresponding empty paper trays, releasing the suction, and leaving the cookies in the paper trays. Subsequently, the finished product conveyor line starts, moving the paper trays containing cookies forward step by step. In this way, through the alternating movement of the first and second suction units, the placement of empty paper trays and the dropping of cookies can be completed simultaneously, which, combined with the stepping movement of the finished product conveyor line, greatly improves production efficiency.

[0018] 2. By controlling the adsorption frequency of the first suction unit, the movement frequency of the empty tray conveyor line, and the movement frequency of the finished product conveyor line, the number of cookies loaded in each paper tray can be adjusted according to actual production requirements.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0022] Please refer to the attached document. Figures 1-9 This embodiment discloses an automatic cookie tray filling device, including: a cookie conveyor line 1, a finished product conveyor line 2 after tray filling, an empty tray conveyor line 3, a mounting frame 4, and a tray-retrieving cavity mechanism 5 and a cookie-retrieving cavity mechanism 6 mounted on the mounting frame 4. Each conveyor line consists of core components such as a belt conveyor, a roller conveyor, and a drive unit. Each conveyor line can be controlled independently by an external control system, allowing for flexible adjustment of the transmission speed to adapt to different production rhythms.

[0023] like Figure 1 and Figure 9 As shown, in order to facilitate batch loading, in some embodiments, the cookies 8 on the cookie conveyor line 1 are arranged in a rectangular array at the first output end 11 after being sorted; similarly, the paper trays 9 on the empty tray conveyor line 3 are also arranged in a rectangular array at the second output end 31.

[0024] like Figure 2 As shown, in some embodiments, this automatic paper tray loading device is arranged in a T-shape. Specifically, the cookie conveyor line 1 and the empty tray conveyor line 3 are located on the left and right sides of the finished product conveyor line 2. Cookies 8 on the cookie conveyor line 1 are conveyed from left to right from the first output end 11 to the input end 21 of the finished product conveyor line 2; at the same time, empty paper trays 9 on the empty tray conveyor line 3 are conveyed from right to left from the second output end 31 to the input end 21. The mounting frame 4 is located on the front side of the conveyor line, the paper tray picking cavity mechanism 5 is mounted on the left side of the mounting frame 4, and the cookie picking cavity mechanism 6 is mounted on the right side of the mounting frame 4.

[0025] In some embodiments, both the paper tray dispensing cavity 5 and the cookie dispensing cavity 6 are connected to an external vacuum fan. The paper tray dispensing cavity 5 and the cookie dispensing cavity 6 are also each equipped with a cylinder for driving the first and second suction sections to move up and down. Specifically, the paper tray dispensing cavity 5 drives the first suction section to move via two cylinders, one cylinder driving the first suction section to move left and right, and the other cylinder driving the first suction section to move up and down. Similarly, the cookie dispensing cavity 6 drives the second suction section to move via two cylinders, one cylinder driving the second suction section to move left and right, and the other cylinder driving the second suction section to move up and down. The number of paper trays 9 sucked up by the first suction section in a single operation is equal to the number of cookies 8 sucked up by the second suction section in a single operation.

[0026] During production, the finished product conveyor line 2 operates intermittently. Initially, the first suction unit is positioned above the second output end 31, and the second suction unit is positioned above the first output end 11. First, the first suction unit descends, absorbing several empty paper trays 9 from the second output end 31. The paper trays 9 are adhered to the first suction unit under negative pressure. Subsequently, the first suction unit, carrying multiple empty paper trays 9, moves from right to left to above the input end 21 of the finished product conveyor line 2, then descends again to place the multiple paper trays 9 on the stationary input end 21; then the adhesion is released, leaving the paper trays 9 on the input end 21. The first suction unit then rises and returns from left to right above the second output end 31, preparing for the next suction action.

[0027] When the first suction unit moves above the input end 21 of the finished product conveyor line 2, the cookie-picking cavity mechanism 6 is activated. The cookie-picking cavity mechanism 6 and the paper tray picking cavity mechanism 5 move at the same speed. When the first suction unit descends and places the paper tray 9, the second suction unit descends synchronously to pick up several cookies 8 from the first output end 11. When the first suction unit rises and returns to the right, the second suction unit carries multiple cookies 8 and moves synchronously from left to right above the input end 21. When the first suction unit descends again to perform the next action of picking up the paper tray 9, the second suction unit descends synchronously, causing multiple cookies 8 to fall one by one into the corresponding empty paper tray 9, and releasing the suction, leaving the cookies 8 in the paper tray 9. Subsequently, the finished product conveyor line 2 is activated, moving the paper tray 9 containing the cookies 8 forward step by step. In this way, through the alternating movement of the first and second suction units, the placement of empty paper trays 9 and the dropping of cookies 8 can be completed simultaneously. Combined with the stepping movement of the finished product conveyor line 2, production efficiency is greatly improved.

[0028] Furthermore, by controlling the adsorption frequency of the first suction unit, the movement frequency of the empty tray conveyor line 3, and the movement frequency of the finished product conveyor line 2, the number of cookies 8 loaded in each paper tray 9 can be adjusted according to actual production requirements. Specifically, taking the example of the first suction unit picking up one row of paper trays 9 at a time, the second suction unit picking up one row of cookies 8 at a time, and one paper tray 9 containing three cookies 8: After the first suction unit places a paper tray 9 once, the external fan is not started during the next two suction actions, so that the first suction unit is idle twice and does not pick up paper trays 9; correspondingly, the empty tray conveyor line 3 stops twice after one step to prevent unpicked paper trays 9 from falling from the end of the second output end 31; the finished product conveyor line 2 stops three times after one step before performing the next movement to ensure that the same batch of paper trays 9 always stays in the original position.

[0029] See Figure 3 In some embodiments, the automatic cookie tray filling device further includes a cookie recycling mechanism 10, which is disposed within the receiving space 41 and located below the cookie-taking cavity mechanism 6. The cookie recycling mechanism includes a first conveyor line 101 and a second conveyor line 102 connected in sequence, with the first conveyor line 101 located directly below the cookie-taking cavity mechanism 6. A recycling bin can be placed at the output end of the second conveyor line 102. In actual production, if the second suction unit fails to hold the cookie 8 securely, the fallen cookie 8 will fall onto the first conveyor line 101 and be transported sequentially via the first conveyor line 101 and the second conveyor line 102, and stored in the recycling bin. Furthermore, the first conveyor line 101 can also be slidably mounted on the mounting frame 4 via a slide rail, allowing it to be pulled out for inspection or cleaning when the automatic cookie tray filling device is stopped.

[0030] like Figure 1As shown, in some preferred embodiments, the cookie conveyor line 1 and the finished product conveyor line 2 are directly connected in the front-to-back direction, and the empty tray conveyor line 3 is located directly above the finished product conveyor line 2. See also Figure 9 The distance between the second output terminal 31 and the first output terminal 11 is greater than the distance between the input terminal 21 and the first output terminal 11, thus leaving space on the input terminal 21 for placing the paper tray 9 and the cookie 8. The mounting frame 4 is located between the cookie conveyor line 1 and the finished product conveyor line 2, and the first output terminal 11 and the input terminal 21 respectively extend into the receiving space 41 of the mounting frame 4. At this time, the cookie-picking cavity mechanism 6 and the paper tray-picking cavity mechanism 5 are respectively installed on the left and right sides of the mounting frame 4 and located within the receiving space 41. See also Figure 1 and Figure 2 Compared with the T-shaped arrangement, this arrangement can save floor space, and the paper tray picking cavity mechanism 5 and the cake picking cavity mechanism 6 have a more compact structure, thus allowing more automatic paper tray loading devices to be installed in a limited production space.

[0031] like Figures 4 to 8 As shown, in some embodiments, the paper tray cavity mechanism 5 includes a first motor 51, a first multi-stage synchronous belt assembly 52, two first rocker arms 53, and a paper tray suction member 54. Specifically, the first motor 51 is mounted on the left inner wall of the mounting frame 4 by fasteners. The first multi-stage synchronous belt assembly 52 is composed of multiple synchronous belt assemblies, each of which includes a driving pulley, a driven pulley, and a synchronous belt. There is one first-stage synchronous belt assembly, and two for each of the remaining stages, which are respectively mounted on the left and right sides of the mounting frame 4. The driving pulley of the first-stage synchronous belt assembly is mounted on the output shaft of the first motor 51. Each stage of driven pulley is coaxially connected to the driving pulley of the next stage of synchronous belt assembly. The driving pulley of the last stage of synchronous belt assembly is rotatably connected to one end of the first rocker arm 53, and the driven pulley of the last stage of synchronous belt assembly is coaxially connected to the swing end of the first rocker arm 53. The left and right ends of the paper tray suction member 54 are respectively fixedly sleeved on the swing ends of the two first rocker arms 53 and located within the accommodating space 41.

[0032] The paper tray suction member 54 is the first suction part of the paper tray taking cavity mechanism 5. Multiple vertically downward-facing first suction heads 541 are provided at the bottom of the paper tray suction member 54. Specifically, the multiple first suction heads 541 are spaced apart along the length direction of the paper tray suction member 54, and some first suction heads 541 are spaced apart along the width direction of the paper tray suction member 54, that is, the multiple first suction heads 541 are arranged in multiple rows. A first air chamber 542 for air circulation is provided inside the paper tray suction member 54. The first air chamber 542 is connected to the outside through multiple first air vents 5421. An external vacuum fan is connected to the first air vent 5421 at the top of the first air chamber 542, and each first air vent 5421 at the bottom of the first air chamber 542 is connected to one of the first suction heads 541.

[0033] During operation, the first motor 51 drives the drive wheel of the first-stage synchronous belt assembly to rotate, which in turn drives the synchronous belt assemblies on both sides to rotate, thereby driving the first rocker arms 53 and the paper tray suction components 54 on both sides to swing along an arc-shaped trajectory. The starting point of this arc-shaped trajectory is located above the second output end 31, and the ending point is located above the input end 21 of the finished product conveyor line 2. After multiple first suction heads 541 adsorb multiple rows of paper trays 9 at the starting point, they swing to the ending point and release, completing the delivery of multiple rows of paper trays 9.

[0034] like Figure 5 As shown, similar to the paper tray cavity mechanism 5, the cookie-taking cavity mechanism 6 includes a second motor 61, a second multi-stage synchronous belt assembly 62, two second rocker arms 63, and a cookie-collecting component 64. Specifically, the second motor 61 is mounted on the right side wall of the mounting frame 4 by fasteners. The second multi-stage synchronous belt assembly 62 is also composed of multi-stage synchronous belt assemblies, each stage of which includes a driving pulley, a driven pulley, and a synchronous belt. There is one first-stage synchronous belt assembly, and two for each of the remaining stages, mounted on the left and right sides of the mounting frame 4 respectively. The driving pulley of the first-stage synchronous belt assembly is mounted on the output shaft of the second motor 61. Each stage of driven pulley is coaxially connected to the driving pulley of the next stage of synchronous belt assembly. The driving pulley of the last stage of synchronous belt assembly is rotatably connected to one end of the second rocker arm 63, and the driven pulley of the last stage of synchronous belt assembly is coaxially connected to the swing end of the second rocker arm 63. The left and right ends of the cookie-collecting component 64 are fixedly sleeved on the swing ends of the two second rocker arms 63 and located within the accommodating space 41.

[0035] The cookie suction member 64 is the second suction part of the cookie-taking cavity mechanism 6. Multiple vertically downward-facing second suction heads 641 are provided at the bottom of the cookie suction member 64. Specifically, the multiple second suction heads 641 are spaced apart along the length direction of the cookie suction member 64, and some second suction heads 641 are spaced apart along the width direction of the cookie suction member 64, that is, the multiple second suction heads 641 are arranged in multiple rows. A second air chamber 642 for air circulation is provided inside the cookie suction member 64. The second air chamber 642 is connected to the outside through multiple second vents 6421. An external vacuum fan is connected to the second vent 6421 at the top of the second air chamber 642, and each second vent 6421 at the bottom of the second air chamber 642 is connected to one of the second suction heads 641.

[0036] During operation, the second motor 61 drives the drive wheel of the first-stage synchronous belt assembly to rotate, thereby driving each stage of the synchronous belt assembly on both sides to rotate in sequence. This causes the second rocker arms 63 and the cookie suction pieces 64 on both sides to swing in an arc-shaped trajectory. The starting point of the arc-shaped trajectory is located above the first output end 11, and the ending point of the arc-shaped trajectory is located above the input end 21. After multiple second suction heads 641 adsorb multiple rows of cookies 8 above the first output end 11, they swing to the input end 21, and then release the adsorption, placing the multiple rows of cookies 8 into the corresponding multiple rows of paper trays 9.

[0037] Compared to the cylinder-driven method, this drive method uses a motor and a multi-stage synchronous belt to work with the rocker arm to achieve reciprocating circular oscillation, which has several advantages: on the one hand, the motion trajectory is smooth and impact-free, which can reduce damage to the paper tray 9 and cookie 8; on the other hand, the synchronous belt transmission has high precision and good repeatability, which can ensure that the paper tray 9 and cookie 8 are accurately picked up and accurately placed.

[0038] In some implementations, tensioning pulleys can be added to each stage of the synchronous belt assembly as needed to further improve transmission accuracy.

[0039] like Figure 4 As shown, preferably, the first multi-stage synchronous belt assembly 52 has a three-stage structure. Specifically, the first multi-stage synchronous belt assembly 52 includes a first synchronous belt assembly 521, two second synchronous belt assemblies 522, and two third synchronous belt assemblies 523. The first synchronous belt assembly 521 includes a first driving pulley 5211, a first driven pulley 5212, and a first synchronous belt 5213. The first driving pulley 5211 is mounted on the output shaft of the first motor 51, the first driven pulley 5212 is fixedly sleeved on a fixed shaft on the left outer wall of the mounting bracket 4, and the first synchronous belt 5213 is sleeved around the first driving pulley 5211 and the first driven pulley 5212. The two second synchronous belt assemblies 522 are respectively mounted on the left and right sides of the mounting bracket 4. The second synchronous belt assembly 522 includes a second driving pulley 5221, a second driven pulley 5222, and a second synchronous belt 5223. The second driving pulley 5221 is coaxially connected to the first driven pulley 5212 via the same rotating shaft, and the two second driving pulleys 5221 are linked by a transmission shaft passing through the mounting frame 4. The second driven pulley 5222 is rotatably connected to the mounting frame 4. The second synchronous belt 5223 is sleeved around the second driving pulley 5221 and the second driven pulley 5222. One end of the first rocker arm 53 is coaxially connected to the second driven pulley 5222 via a bearing. Both third synchronous belt assemblies 523 include a third driving pulley 5231, a third driven pulley 5232, and a third synchronous belt 5233. Each third driving pulley 5231 is pivotally connected to the rotating end of the first rocker arm 53 on both sides, and each third driven pulley 5232 is pivotally connected to the swinging end of the first rocker arm 53 on both sides. The third synchronous belt 5233 is sleeved around the third driving pulley 5231 and the third driven pulley 5232.

[0040] The purpose of setting the first multi-stage synchronous belt assembly 52 as a three-stage structure is that, compared to a two-stage structure, the three-stage structure can achieve a larger reduction ratio by increasing the number of transmission stages without increasing the pulley diameter, thereby increasing the output torque. This allows a smaller power motor to drive a relatively large oscillating load composed of the first rocker arm 53 and the paper tray suction member 54. Compared to a four-stage or higher structure, the three-stage structure simplifies the structure while ensuring transmission performance.

[0041] like Figure 5 As shown, in a preferred embodiment, the second multi-stage synchronous belt assembly 62 similarly has a three-stage structure. The second multi-stage synchronous belt assembly 62 includes a fourth synchronous belt assembly 621, two fifth synchronous belt assemblies 622, and two sixth synchronous belt assemblies 623. The fourth synchronous belt assembly 621 includes a fourth driving pulley 6211, a fourth driven pulley 6212, and a fourth synchronous belt 6213. The fourth driving pulley 6211 is mounted on the output shaft of the second motor 61, the fourth driven pulley 6212 is fixedly sleeved on a fixed shaft on the right outer wall of the mounting frame 4, and the fourth synchronous belt 6213 is sleeved around the fourth driving pulley 6211 and the fourth driven pulley 6212. The two fifth synchronous belt assemblies 622 are respectively mounted on the left and right sides of the mounting frame 4. The fifth synchronous belt assembly 622 includes a fifth driving pulley 6221, a fifth driven pulley 6222, and a fifth synchronous belt 6223. The fifth driving pulley 6221 is coaxially connected to the fourth driven pulley 6212 via the same rotating shaft, and the two fifth driving pulleys 6221 are linked by another transmission shaft passing through the mounting frame 4. The fifth driven pulley 6222 is rotatably connected to the mounting frame 4. The fifth synchronous belt 6223 is sleeved around the fifth driving pulley 6221 and the fifth driven pulley 6222. One end of the second rocker arm 63 is coaxially connected to the fifth driven pulley 6222 via a bearing. Both sixth synchronous belt assemblies 623 include a sixth driving pulley 6231, a sixth driven pulley 6232, and a sixth synchronous belt 6233. Each sixth driving pulley 6231 is pivotally connected to the rotating end of the second rocker arm 63 on both sides, and each sixth driven pulley 6232 is pivotally connected to the swinging end of the second rocker arm 63 on both sides. The sixth synchronous belt 6233 is sleeved around the sixth driving pulley 6231 and the sixth driven pulley 6232.

[0042] The purpose of setting the second multi-stage synchronous belt assembly 62 as a three-stage structure is that, compared to a two-stage structure, the three-stage structure can achieve a larger reduction ratio by increasing the number of transmission stages without increasing the pulley diameter, thereby increasing the output torque. This allows a smaller power motor to drive a larger oscillating load composed of the second rocker arm 63 and the cookie-cutter suction member 64. Compared to four-stage or higher structures, the three-stage structure simplifies the structure while ensuring transmission performance.

[0043] like Figure 6As shown, in some embodiments, the paper tray picking cavity mechanism 5 further includes a first cylinder 55. Specifically, two first cylinders 55 are respectively installed at the left and right ends of the paper tray suction member 54, and swing with the paper tray suction member 54. When the paper tray suction member 54 swings above the second output end 31, the first cylinder 55 drives the paper tray suction member 54 to descend, pick up the paper tray 9, and then rise. When the suction member carrying the paper tray 9 swings above the input end 21 of the finished product conveyor line 2, the first cylinder 55 drives the suction member to descend again, placing the paper tray 9 stably on the input end 21 to avoid positional displacement during placement.

[0044] like Figure 7 As shown, in some embodiments, the cookie-collecting cavity mechanism 6 further includes a second cylinder 65, which is driven by the cookie suction member 64 to move the cookie suction member 64 up and down. Specifically, two second cylinders 65 are respectively installed at the left and right ends of the cookie suction member 64, and swing with the cookie suction member 64. When the cookie suction member 64 swings above the first output end 11, the second cylinder 65 drives the cookie suction member 64 to descend, suck up the cookie 8, and then rise; when the suction member carrying the cookie 8 swings above the input end 21, the second cylinder 65 drives the suction member to descend again, smoothly placing the cookie 8 into the paper tray 9. By adjusting the lifting stroke of the second cylinder 65, it can be adapted to the stacking height of different numbers of cookies, avoiding breaking the cookies.

[0045] like Figures 4 to 5 As shown, in some embodiments, the paper tray cavity mechanism 5 further includes two first connecting rods 56 and two first shock absorbers 57. One end of each of the two first connecting rods 56 is respectively connected to a fixed shaft on which the second driven wheels 5222 are located on both sides via bearings, and the other end of each first connecting rod 56 is pivotally connected to one end of each first shock absorber 57; the other end of each first shock absorber 57 is rotatably connected to a fixed shaft on the side wall of the mounting frame 4. Specifically, the main body of the first shock absorber 57 is a plurality of longitudinally spaced spring rods. The second driven wheels 5222 sequentially drive the first connecting rods 56 and the first shock absorbers 57 to swing, causing the first shock absorbers 57 to elastically stretch or contract to absorb impact and vibration, thereby suppressing the inertial shaking of the paper tray suction member 54 at the beginning and end of the swing trajectory, making the suction and placement of the paper tray 9 more stable and accurate.

[0046] like Figures 4 to 5As shown, in some embodiments, similarly, the cookie-taking cavity mechanism 6 also includes two second connecting rods 66 and two second shock absorbers 67. One end of each of the two second connecting rods 66 is respectively connected to a fixed shaft on both sides of the fifth driven wheel 6222 via bearings, and the other end of each second connecting rod 66 is pivotally connected to one end of each of the second shock absorbers 67; the other end of each of the second shock absorbers 67 is rotatably connected to a fixed shaft on the side wall of the mounting frame 4. Specifically, the main body of the second shock absorber 67 is also a plurality of longitudinally spaced spring rods. The working principle of the second shock absorber 67 is similar to that of the first shock absorber 57, and will not be described again. The function of the second shock absorber 67 is to make the cookie 8 more stably and accurately placed into the paper tray 9.

[0047] like Figure 8 As shown, in some embodiments, the cookie suction member 64 is further provided with a plurality of flexible sleeves 7, which are fitted one-to-one with the suction end of each of the second suction heads 641. Specifically, the flexible sleeves 7 are made of rubber material, and the flexible sleeves 7 elastically abut against the cookie 8 when the second suction head 641 descends to suck up the cookie, avoiding direct contact between the rigid second suction head 641 and the cookie 8 and thus preventing the cookie 8 from being broken.
