Description

Technical Field

[0001] This invention belongs to the technical field of commercial kitchen automation equipment, and relates to an automatic stacking device, particularly an automatic stacking device for serving bowls. Background Technology

[0002] In the commercial kitchen equipment sector, serving bowls are commonly used containers in the catering industry and require continuous cleaning in long-line washing machines after use. Currently, the output and storage of serving bowls after cleaning in existing washing machines generally rely on manual handling, stacking, and placement. This requires dedicated personnel to continuously monitor the equipment exit, resulting in high labor costs, low efficiency, and difficulty in keeping up with the continuous high-speed output of the washing equipment, easily leading to bowl accumulation and blockage. Furthermore, the instability of manual operation makes it prone to problems such as bowl collisions, tipping over, and uneven stacking, affecting operational continuity and equipment efficiency.

[0003] With the development of automation and intelligence in commercial kitchens, some automated stacking equipment has also emerged. However, existing automated stacking equipment generally suffers from complex control logic and cumbersome electrical and mechanical linkages, making it prone to malfunctions, high downtime rates, and difficult maintenance. During the conveying, release, stacking, and vehicle-changing of serving dishes, the coordination of actions is poor and the reliability of operation is low, which can easily lead to jamming, uneven stacking, and system interruptions. It cannot meet the needs of commercial kitchen equipment for simple, stable, reliable, continuous, and efficient automated operation. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the prior art by proposing an automatic stacking device for counting trays. It solves the technical problems of complex control and poor operational reliability in existing automatic stacking devices for counting trays.

[0005] The objective of this invention can be achieved through the following technical solutions: An automatic stacking device for serving basins includes a transfer platform for docking with the end-of-line transfer track of a long-line washing machine and a lifting trolley for stacking serving basins. The transmission platform is equipped with a slide for a single row of dispensing basins to pass through on the transmission track. The slide has a downward sloping surface along its transmission direction, allowing the dispensing basins to move along the slope under the action of their own gravity and / or transmission thrust. The slide is located at the end of the slope and has a drop opening that allows a single serving of basins to pass through. The slide is hinged to a releaseable flap at the drop opening. When the flap is released downward, the drop opening is opened to allow the basins to fall. When the flap is reset upward, it can block the drop opening and be configured to support a single serving of basins. The slide is equipped with a blocking component near the drop opening to prevent the distribution trays in the slide from passing through. The blocking component and the flap are connected by a linkage assembly, and an electric drive component is connected to the linkage assembly. When the flap is released downward, it can descend synchronously to block the distribution trays in the slide. When the flap is reset upward, it can rise synchronously to allow the distribution trays to pass through, realizing synchronous linkage movement of the flap and the blocking component in the same direction. The lifting trolley includes a trolley body and a stacking platform. The stacking platform is located below the aforementioned drop opening to receive stacked trays as they fall. The stacking platform is slidably connected to the trolley body and can slide vertically relative to the trolley body. A spring support is provided between the stacking platform and the trolley body. The spring is configured to be stretched as the number of stacked trays increases, so that the height of the stacking platform can be adaptively adjusted.

[0006] This application enables the dispensing basins to move along the slope under their own gravity and / or transmission thrust by setting up a transmission platform, slide, and downward sloping surface. No additional complex conveying structure is required, and the control is simple and the operation is highly reliable.

[0007] The slide end features a drop opening and a hinged flap, facilitating the release and support of serving trays. The mechanism is simple and operates stably. A linkage assembly connects the blocking component and the flap, which are synchronously driven by an electric drive unit. This ensures synchronized movement of the flap and blocking component in the same direction, achieving dual control actions with a single drive source. This significantly simplifies control logic, improves operational reliability, and prevents jamming caused by multiple trays entering the drop opening simultaneously. The stacking platform of the lifting trolley is slidably connected to the trolley body and uses spring support for adaptive height adjustment. The purely mechanical structure enables automatic adjustment of the receiving height, eliminating complex electrical controls, simplifying control, and ensuring reliable operation, thus guaranteeing stable stacking of serving trays.

[0008] In the above-mentioned automatic stacking device for serving trays, there is a height difference between the platform and the transport track. A connecting frame is provided between the platform and the transport track for connecting the two. The connecting frame is provided with a guide surface with a slope greater than the slope surface to guide the serving trays into the slide.

[0009] A connecting frame is set between the transmission platform and the transmission track. The guide surface with a larger slope guides the dispensing tray into the slide, so that the dispensing tray can smoothly transition between different heights of the transmission surface. The structure is simple, the operation is reliable, and the transmission jamming is avoided.

[0010] In the aforementioned automatic stacking device for serving basins, the slope of the ramp is 5°.

[0011] The slope is limited to 5°, which is a reasonable slope setting that ensures smooth movement of the trays without causing impact and stacking due to excessive speed. It is simple to control and runs stably and reliably.

[0012] In the above-mentioned automatic stacking device for dispensing basins, several evenly spaced rollers are installed on the slope along its transmission direction to facilitate the smooth movement of the dispensing basins along the slope.

[0013] By setting several evenly spaced rollers on the slope, the resistance to the movement of the rollers is reduced, making them move more smoothly along the slope. The structure is simple, not easy to get stuck, and has high operational reliability.

[0014] In the above-mentioned automatic stacking device for serving trays, the flap has two symmetrically arranged flaps, each flap being hinged to one side of the slide, and the flaps are configured to have the same tilt direction and tilt angle as the slope. Each of the aforementioned flaps is equipped with rollers arranged in the same direction as the rollers, which facilitates the smooth movement of the serving trays onto the flaps to enter the release state.

[0015] The device employs two symmetrically arranged flaps, with the flaps tilting in the same direction and angle as the slope, resulting in more stable support. Rollers are installed on the flaps to facilitate the smooth movement of the portion trays onto the flaps to enter the release state. The structure is simple, the operation is reliable, and it effectively improves the stability of conveying and releasing.

[0016] In the aforementioned automatic stacking device for serving trays, a mounting frame is fixed on the transmission platform. The mounting frame is located above the drop opening of the slide. The linkage assembly includes a fork arm, a fork arm, and a swing arm. The middle part of the swing arm is hinged to the mounting frame. One end of the swing arm is connected to the flip plate through the fork arm, and the other end of the swing arm is connected to the blocking member through the fork arm. The electric drive unit is fixed on the mounting frame and can drive the swing arm to swing.

[0017] The linkage assembly consists of a mounting frame, fork arm one, fork arm two, and a swing arm. The middle of the swing arm is hinged to the mounting frame. One end is connected to a flap via fork arm one, and the other end is connected to a blocking component via fork arm two. The electric drive unit drives the swing arm to swing, thus achieving synchronous linkage. The overall mechanical linkage structure is simple, the control logic is concise, and the operation reliability is high.

[0018] In the aforementioned automatic stacking device for serving trays, the fork arm includes two connecting rods that are hinged to each other. One end of each connecting rod is hinged to the other and intersects with one end of the swing arm. The other end of each connecting rod is hinged to a flap. The hinge position between the connecting rod and the flap is located outside the intersection of the flap and the slide, thereby enabling the connecting rod to descend and push the flap to close the drop opening.

[0019] The hinge position between the connecting rod of the fork arm and the flap is defined so that the lowering of the connecting rod pushes the flap to close the lower opening. The transmission relationship is direct and clear, the structure is simple, the action is precise and reliable, and transmission jamming is avoided.

[0020] In the above-mentioned automatic stacking device for serving bowls, the fork arm includes two connecting rods, one end of each connecting rod is connected to the end of the swing arm, and the other end of each connecting rod is fixed to a blocking member. The blocking member is slidably connected to the mounting frame and can reciprocate in the vertical direction through the connecting rods.

[0021] The blocking component moves vertically back and forth on the mounting frame via a linkage two-drive mechanism. The drive structure is simple, and it is synchronized with the swing arm for linkage response. The control is simple and the operation is stable, effectively realizing the blocking and release of the portion trays.

[0022] In the above-mentioned automatic stacking device for serving bowls, the automatic stacking device also includes a buffer platform disposed below the transmission platform. The buffer platform can move along the transmission direction and has a linkage structure with the lifting trolley. When the lifting trolley enters below the drop opening, the buffer platform moves synchronously in the opposite direction of the transmission direction. When the lifting trolley exits, the buffer platform moves synchronously below the drop opening to receive the serving bowls.

[0023] This application sets up a movable buffer platform and forms a linkage structure with the lifting trolley. When the lifting trolley enters, the buffer platform makes way, and when the lifting trolley exits, the buffer platform receives the containers, realizing continuous operation without stopping the machine when changing trolleys. The linkage structure is simple and the control is concise, improving the continuity and reliability of the device operation.

[0024] In the above-mentioned automatic stacking device for counting trays, a slide rail arranged along the conveying direction of the counting trays is installed below the conveying platform, and the buffer platform is slidably connected to the slide rail. The linkage structure includes a baffle plate connected between the slide rail and the buffer platform to push the buffer platform to always maintain the tendency to move in the conveying direction. The buffer platform is provided with a baffle plate on its side. When the buffer trolley is pushed in, it abuts against the baffle plate to push the buffer platform to move aside, and the state is maintained by locking the universal wheels on the buffer trolley. The height of the stacking platform on the cache cart is lower than the height of the cache platform, and a crossbar is fixed on the side of the transmission platform below the drop port and away from the transmission direction. When the cache cart enters, the crossbar can prevent the stacked trays on the cache platform from entering the stacking platform.

[0025] This application utilizes a sliding rail and a linkage structure that forms a buffer platform. The buffer platform achieves automatic reset and clearance, and, in conjunction with the baffle and crossbar, achieves reliable limiting and positioning. The entire process uses a mechanical structure to achieve linkage and limiting, without complex electrical control. The control is simple, the operation is stable and reliable, and the process of changing vehicles is safe and smooth.

[0026] The advantages of this invention compared to the prior art are as follows: 1. The overall device structure and control logic are simple. It uses a single electric drive component in conjunction with a linkage assembly to achieve synchronous linkage between the flap and the blocking component. The action is simple and reliable, effectively avoiding jamming of the dispensing trays and ensuring high operational stability.

[0027] 2. The slide uses a downward sloping surface combined with rollers, and the trays can move automatically by gravity or transmission thrust, ensuring smooth conveying without the need for a complex conveying structure.

[0028] 3. The combination of the flapper and rollers can stably support the portion trays and smoothly guide them into the release state. The release and reset actions are reliable, ensuring a stable conveying and release process.

[0029] 4. The stacking platform achieves height self-adjustment through spring support. It adopts a purely mechanical structure, requiring no complex electrical control, and ensures precise reception of trays and neat stacking.

[0030] 5. The buffer platform and the lifting trolley are linked by a mechanical structure to achieve continuous operation without stopping the machine when changing vehicles, ensuring that the overall operation process is uninterrupted and the operation is highly continuous.

[0031] 6. The device has a low overall failure rate, is easy to maintain, simple to control, and has high operational reliability. It can efficiently and stably complete the entire process of automatic conveying, releasing, and stacking of portion trays. Attached Figure Description

[0034] To make the technical solution, purpose, and beneficial effects of the present invention clearer, the present invention will be described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are only for illustrating the present invention and are not intended to limit the present invention.

[0035] like Figure 1 The automatic stacking device for serving basins shown includes a transmission platform 2 and a lifting trolley 3. The transmission platform 2 is used to connect with the transmission track 1 at the end of the long-line washing equipment to realize the continuous transportation of serving basins. The lifting trolley 3 is used to receive and stack the delivered serving basins to complete the automatic storage operation.

[0036] The transmission platform 2 is equipped with a slide 21, which allows a single row of serving trays on the transmission track 1 to pass through, preventing multiple trays from blocking each other. The slide 21 has a downward-sloping surface 22 along the transmission direction, allowing the serving trays to move automatically along the slope 22 under their own weight or transmission thrust, without the need for additional power. The structure is simple and the operation is stable. There is a height difference between the transmission platform 2 and the transmission track 1, and a connecting frame 8 is installed between them. The connecting frame 8 has a guide surface 81, the slope of which is greater than the slope of the slope 22, which guides the serving trays smoothly into the slide 21, ensuring a smooth conveying process.

[0037] like Figure 2 The slope 22 is equipped with several evenly spaced rollers 24 along the transmission direction. The rollers 24 form two rows, located on both sides of the slope 22. The edges of the serving trays abut against the two rows of rollers 24. The rollers 24 reduce the moving resistance between the serving trays and the slope 22, making the serving trays move more smoothly and avoiding stagnation due to excessive friction. The slide 21 has a drop opening 23 at the end of the slope 22. The drop opening 23 is large enough for a single serving tray to pass through, realizing the orderly release of a single tray. A flap 4 is hinged at the drop opening 23. Two flaps 4 are symmetrically arranged, each flap 4 is hinged to the side of the slide 21. The arrangement direction of the two flaps 4 is perpendicular to the transmission direction, and the opening and closing direction is at a 90-degree angle to the transmission direction. The tilt direction and tilt angle of the flap 4 are consistent with the slope 22. Rollers 25 are installed on the flap 4. Rollers 25 are arranged in the same direction as rollers 24 to facilitate the smooth movement of the serving tray onto the flap 4 and into the ready-to-release state. When the infrared detector (not shown in the built-in installation diagram) detects that the serving tray is in place, the flap 4 is released, and the serving tray is automatically dropped onto the lifting trolley 3. The flap 4 can be flipped downwards to release, opening the drop opening 23 so that the serving tray can fall below. When the flap 4 is reset upwards, it can block the drop opening 23 and can support a single serving tray, providing stable and reliable support.

[0038] like Figures 1-4As shown, a blocking element 5 is installed near the drop opening 23 on the slide 21. The blocking element 5 can prevent multiple basins from passing through the slide 21, thus preventing multiple basins from entering the drop opening 23 area at the same time. A mounting frame 9 is fixed on the transmission platform 2. The mounting frame 9 is located above the drop opening 23. A linkage assembly 7 is installed on the mounting frame 9. The linkage assembly 7 includes a first fork arm 71, a second fork arm 72, and a swing arm 73. The middle part of the swing arm 73 is hinged to the mounting frame 9. One end of the swing arm 73 is connected to the flip plate 4 through the first fork arm 71, and the other end is connected to the blocking element 5 through the second fork arm 72. An electric drive component 6 is connected to the linkage assembly 7. The electric drive component 6 is preferably an electric telescopic rod. This is an outsourced component, and existing mature technology will not be elaborated on here. The electric telescopic rod drives the swing arm 73 to swing, causing the flap 4 and the blocking part 5 to move synchronously in the same direction. When the flap 4 is released downward, the blocking part 5 descends synchronously to block the serving tray in the slide 21. When the flap 4 is reset upward, the blocking part 5 rises synchronously to allow the serving tray to pass. A single drive source realizes dual action control, the control logic is simple, and the operation is highly reliable.

[0039] like Figure 5 and Figure 6 As shown, the first fork arm 71 includes two hinged connecting rods 711. One end of each connecting rod 711 is hinged to one end of the swing arm 73, and the other end of each connecting rod 711 is hinged to a flap 4. The flap 4 has an upwardly protruding hinge end, and the connecting rod 711 is hinged at the hinge end. The position of the hinge end here is higher than the hinge position between the flap 4 and the drop opening 23. When the connecting rod 711 pushes the hinge end to flip outward, the main body of the flap 4 swings inward toward the drop opening 23 to close the drop opening 23. The transmission is direct and the action is precise. The second fork arm 72 includes two connecting rods 721. One end of each connecting rod 721 is connected to the end of the swing arm 73, and the other end is fixed to the blocking member 5. The blocking member 5 is slidably connected to the mounting bracket 9 and can move back and forth in the vertical direction under the action of the connecting rod 721. The blocking and releasing actions are stable and synchronous.

[0040] like Figure 1 and Figure 3 As shown, the lifting trolley 3 includes a trolley body 31 and a stacking platform 32. The stacking platform 32 is located below the drop opening 23 and is used to receive the falling serving trays. The stacking platform 32 is slidably connected to the trolley body 31 and can slide vertically relative to the trolley body 31. A spring 33 is provided between the stacking platform 32 and the trolley body 31 for support. As the number of stacked serving trays increases, the spring 33 is gradually stretched, causing the stacking platform 32 to adaptively descend, always maintaining a suitable receiving height. No electronic control adjustment is required; the purely mechanical structure is simple to control, provides stable receiving, and ensures neat stacking.

[0041] like Figure 4A buffer platform 26 is installed below the transmission platform 2 shown. The buffer platform 26 can move along the transmission direction of the dispensing trays. A linkage structure is set between the buffer platform 26 and the lifting trolley 3. A slide rail 27 arranged along the transmission direction is installed below the transmission platform 2. The buffer platform 26 is slidably connected to the slide rail 27. The linkage structure includes a return spring (not shown in the figure, the installation position is not limited as long as it can achieve the reset function). The return spring is connected between the slide rail 27 and the buffer platform 26, providing elastic force for the buffer platform 26 to move in the transmission direction. A baffle plate 28 is set on the side of the buffer platform 26. When the lifting trolley 3 is pushed under the drop port 23, it abuts against the baffle plate 28, pushing the buffer platform 26 to move away from the transmission direction along the slide rail 27 to make way. When the lifting trolley 3 is withdrawn, it pushes the buffer platform 26 to automatically move to the drop port 23 to receive the dispensing trays, realizing non-stop operation when changing carts. The height difference between the buffer platform 26 and the stacking platform 32, combined with the crossbar 29 on the transmission platform 2, ensures that when changing trolleys, the stacked trays on the buffer platform 26 can smoothly enter the stacking platform 32 on the new trolley to continue the stacking operation, seamlessly connecting and ensuring continuous and stable operation.

[0042] The return spring is a tension spring. One end of the tension spring is hooked to the front end of the slide rail 27, and the other end is hooked to the base of the buffer platform 26. Travel limit stop pieces 291 are also fixed on both sides of the slide rail 27. When the buffer platform 26 is driven forward by 33, it can form a stop with the travel limit stop piece 291 to limit the forward position and ensure that the buffer platform 26 stops accurately at the drop port 23.

[0043] like Figures 1-6 When the device is working, the serving basins are transported to the connecting frame 8 via the washing equipment transfer track 1, and enter the slide 21 of the transfer platform 2 along the guide surface 81. Under the action of gravity, they move along the slope 22 and the roller 24 to the flip plate 4. The electric drive unit 6 drives the flip plate 4 to release downward through the linkage assembly 7. At the same time, the blocking part 5 descends synchronously to block the subsequent serving basins. The serving basins fall through the drop port 23 onto the stacking platform 32 of the lifting trolley 3. The spring 33 adaptively stretches as the number of serving basins increases, adjusting the receiving height. When the number of serving trays on the stacking platform 32 reaches the set quantity, it will be detected by the lower height limit infrared detector (the built-in detector is not shown in the diagram) and the signal will be sent to the audible and visual alarm device of the cleaning system to remind the operator to replace the lifting trolley 3 in time. After the lifting trolley 3 is removed, the buffer platform 26 will move to the bottom of the drop port 23 to temporarily receive the serving trays. After the new lifting trolley 3 is replaced, the buffer platform 26 will move aside and the device will continue to operate. If a blockage occurs at the end, the blockage infrared detector at the front end of the transmission platform 2 (not shown in the diagram) will detect the abnormal signal and cause the conveyor belt of the cleaning system to stop running. After the abnormality is eliminated, the system will continue to run. The entire process is simple to control, reliable to operate, and efficiently completes the automatic conveying, release and stacking of serving trays.
