[0002] In catering establishments such as restaurants, canteens, and buffets, the storage, retrieval, and replenishment of plates are crucial aspects of daily operations. Currently, plates are typically stacked and stored in fixed lockers, workbenches, or food carts. Placing plates on workbenches or food carts poses hygiene and safety risks; exposed portions of stacked plates are prone to dust accumulation or contamination, affecting food hygiene. Storing plates in lockers usually requires significant floor space, and stacked plates too high pose a risk of tipping over, potentially causing breakage, economic losses, and safety hazards. Furthermore, all of these plate storage methods suffer from low vertical space utilization; storing a large number of plates requires substantial floor or platform space, which is particularly inconvenient in the already limited space of the kitchen or front-of-house area of ​​a catering establishment.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] like Figures 1 to 5 As shown, a tray lifting and storage device includes a frame 1, a first synchronous belt 2, and a second synchronous belt 3. The frame 1 is vertically positioned, thus effectively utilizing vertical space and saving floor space. To more clearly demonstrate how the device operates, in Figures 1 to 5 Each plate contains 100 servings.

[0022] The first synchronous belt 2 and the second synchronous belt 3 are mounted on the frame 1. Both the first synchronous belt 2 and the second synchronous belt 3 are arranged vertically along the frame 1, and are facing each other and parallel to each other. A space for placing the tray 100 is formed between the first synchronous belt 2 and the second synchronous belt 3. Multiple limiting guide rails 11 are correspondingly arranged on the outer surfaces of the first synchronous belt 2 and the second synchronous belt 3. These multiple limiting guide rails 11 are evenly spaced along the conveying direction of the first synchronous belt 2 or the second synchronous belt 3, and each limiting guide rail 11 is arranged along the width direction of the first synchronous belt 2 or the second synchronous belt 3. The number of limiting guide rails 11 on the first synchronous belt 2 and the second synchronous belt 3 is equal, and they correspond one-to-one in the horizontal direction. Corresponding pairs of limiting guide rails 11 are used to support the tray 100.

[0023] Definition: The distance between two adjacent limit rails 11 in the first synchronous belt 2 or the second synchronous belt 3 is one division. The width direction of the first synchronous belt 2 or the second synchronous belt 3 is the front-to-back direction, and the first synchronous belt 2 and the second synchronous belt 3 are arranged in the left-to-right direction.

[0024] like Figures 6 to 8 As shown, both the first synchronous belt 2 and the second synchronous belt 3 are driven to operate synchronously by a drive mechanism. The drive mechanism includes a first drive shaft 4, a second drive shaft 5, a first driven shaft 6, a second driven shaft 7, a first double gear 8, a second double gear 9, and a drive motor 10. Both the first double gear 8 and the second double gear 9 include a pinion and a gear. Specifically, a drive gear 401 is provided at one end of the first drive shaft 4 and one end of the second drive shaft 5, and a drive synchronous pulley 402 is provided at the middle position of both the first drive shaft 4 and the second drive shaft 5. A driven synchronous pulley 601 is provided at the middle position of both the first driven shaft 6 and the second driven shaft 7. The structure of the first driven shaft 6 is as follows... Figure 8As shown, bases 403 are rotatably connected to both ends of the first drive shaft 4, the second drive shaft 5, the first driven shaft 6, and the second driven shaft 7, and the bases 403 are mounted on the frame 1. The bottom end of the first synchronous belt 2 is connected to the drive synchronous pulley 402 on the first drive shaft 4, and the top end of the first synchronous belt 2 is connected to the driven synchronous pulley 601 on the first driven shaft 6. Similarly, the bottom end of the second synchronous belt 3 is connected to the drive synchronous pulley 402 on the second drive shaft 5, and the top end of the second synchronous belt 3 is connected to the driven synchronous pulley 601 on the second driven shaft 7. The pinion of the first double gear 8 is connected to the drive gear 401 on the first drive shaft 4 via the first gear chain 801. The pinion of the second double gear 9 is connected to the drive gear 401 on the second drive shaft 5 via the second gear chain 901. The large gears of the first double gear 8 and the second double gear 9 mesh with each other. The end of either the first double gear 8 or the second double gear 9 is connected to a drive motor 10. The output shaft of the drive motor 10 is connected to either the first double gear 8 or the second double gear 9. Power transmission can be completed through only one drive motor 10. In this embodiment, the output shaft of the drive motor 10 is connected to the first double gear 8.

[0025] The pinions on the first double gear 8 and the second double gear 9, as well as the driving gear 401, can be considered as sprockets. The first gear chain 801 and the second gear chain 901 refer to chains that can mesh with the pinions on the double gears for transmission.

[0026] A mounting bracket 101 is provided on the frame 1. The mounting bracket 101 has an L-shaped cross-section and extends along the left and right directions of the frame 1. The mounting bracket 101 is located behind the first synchronous belt 2 and the second synchronous belt 3. The first double gear 8 and the second double gear 9 are mounted on one side of the mounting bracket 101, and the drive motor 10 is mounted on the other side of the mounting bracket 101. A first tensioning wheel 802 is also provided on the first gear chain 801. The first tensioning wheel 802 is used to tension the first gear chain 801 and is connected to the mounting bracket 101. Specifically, the mounting bracket 101 is provided with an elongated through hole, and one end of the rotating shaft of the first tensioning wheel 802 is slidably connected in the elongated through hole. The mounting bracket 101 is also provided with a bracket 107, and the rotating shaft of the first tensioning wheel 802 is connected to the bracket 107 by bolts. Therefore, the first tensioning wheel 802 adjusts the tension of the first gear chain 801 by means of these bolts. Similarly, a second tensioning wheel 902 is also provided on the second gear chain 901. The second tensioning wheel 902 is used to tension the second gear chain 901. The second tensioning wheel 902 is connected to the mounting bracket 101 in the same way as the first tensioning wheel 802, which will not be described in detail here.

[0027] like Figure 1As shown, a tray placement inlet 106 is provided on the frame 1, and a limiting mechanism 12 is provided at the tray placement inlet 106. The limiting mechanism 12 is located on the front side of the area between the first synchronous belt 2 and the second synchronous belt 3. Figure 9 and Figure 10 As shown, the limiting mechanism 12 includes linear guide rails 13, limiting tracks 14, and limiting cylinders 15. Two linear guide rails 13 are provided, arranged on the upper and lower sides of the plate placement inlet 106, with each linear guide rail 13 extending in the left-right direction. Two limiting tracks 14 are also provided, each with a slider 141 at both ends. The sliders 141 at both ends of one limiting track 14 connect to one corresponding end of the two linear guide rails 13, and the sliders 141 at both ends of the other limiting track 14 connect to the other corresponding end of the two linear guide rails 13, forming a rectangular structure between the limiting tracks 14 and the linear guide rails 13. A limiting cylinder 15 is provided on each limiting track 14. The movable end of the limiting cylinder 15 is connected to the limiting track 14, and the fixed end of the limiting cylinder 15 is connected to the frame 1. The limiting cylinder 15 is used to drive the limiting track 14 to slide on the linear guide rails 13, thereby blocking the plate placement inlet 106. Limiting blocks 142 are provided at the bottom of the two limiting tracks 14. The limiting blocks 142 move horizontally together with the limiting tracks 14. The two limiting blocks 142 are set horizontally facing each other. When the plate 100 is placed, each limiting block 142 is on the same straight line as one of the limiting guide rails 11 on the same side. Therefore, the limiting blocks 142 can assist the limiting guide rails 11 in replenishing the plate 100.

[0028] like Figure 2 , Figure 4 and Figure 5 As shown, the frame 1 is also provided with two limiting strips 102, each of which is arranged vertically along the frame 1. One limiting strip 102 is located between the rear side of the first synchronous belt 2 and the rear side of the second synchronous belt 3, and the other limiting strip 102 is located between the front side of the first synchronous belt and the front side of the second synchronous belt. The limiting strips 102 are used to fix the plate 100 in the front-back direction. The limiting strip 102 located on the rear side extends from the top of the frame 1 to the bottom of the frame 1; while the limiting strip 102 located on the front side extends from the top of the frame 1 to the top of the limiting mechanism 12. This is because at the position of the limiting mechanism 12, the limiting rail 14 can fix the plate 100. The limiting strips 102 are made of nylon material, which is wear-resistant and prevents scratches on the plate 100.

[0029] The frame 1 is also equipped with a first sensor 103, a second sensor 104, and a third sensor 105. The transmitter and receiver of the first sensor 103 are located at the front and rear positions of the bottom of the frame 1, respectively. The first sensor 103 is used to monitor whether the limit guide rail 11 needs to be replenished with a plate 100. If there is no plate 100 in the limit guide rail 11, it is replenished; otherwise, the position is skipped. The transmitter and receiver of the second sensor 104 are located at the top and bottom of the limit mechanism 12, respectively. The second sensor 104 is used to monitor whether the plate 100 is placed in place on the limit guide rail 11. The transmitter and receiver of the third sensor 105 are located at the front and rear positions of the top of the frame 1, respectively. The third sensor 105 is used to monitor whether the plates 100 on the first synchronous belt 2 and the second synchronous belt 3 are replenished to a full load state. The first sensor 103, the second sensor 104, and the third sensor 105 are all through-beam photoelectric sensors. Through-beam photoelectric sensors are existing technology and will not be described in detail here.

[0030] The operation steps of this device are as follows: When storing a plate 100, the first sensor 103 monitors whether a plate 100 needs to be added to the limiting guide rail 11. If there is no plate 100 in the limiting guide rail 11, it is added. At this time, a set of stacked plates 100 are put into the plate inlet 106. The two sides of the bottom plate 100 are pressed against the limiting blocks 142 on both sides. Then, the limiting blocks 142 push the plate 100 to the limiting guide rail 11. The plate 100 is pressed against the limiting guide rail 11 on both sides. At this time, the second sensor 104 will monitor whether the plate 100 is placed in place and adjust the plate 100 accordingly. The plate 100 can be placed multiple times until it fills the space of the current limiting guide rail 11. The subsequent plates 100 are directly stacked on the previous plates 100. Once the current space occupied by the limiting guide rail 11 is filled, the two limiting cylinders 15 activate. The limiting cylinders 15 drive the limiting rail 14 to slide on the linear guide rail 13, causing the two limiting rails 14 to engage. At this point, the plate 100 is fixed in both front-to-back and left-to-right directions under the combined action of the first synchronous belt 2, the second synchronous belt 3, the limiting rail 14, and the limiting strip 102 located at the rear. Then, the drive motor 10 drives the first double gear 8 to rotate, which in turn drives the second double gear 9 to rotate, causing the first synchronous belt 2 and the second synchronous belt 3 to rotate in opposite directions. The corresponding limiting guide rail 11 moves upward. The drive motor 10 pauses after each one-space movement. The plate 100 located above the limiting mechanism 12 is then fixed in both front-to-back and left-to-right directions under the combined action of the first synchronous belt 2, the second synchronous belt 3, and the two limiting strips 102. When it is necessary to store the plate 100 again, the limiting rail 14 is reset by the limiting cylinder 15, and the above operation is repeated to place the plate 100. When the third sensor 105 detects that the plate 100 has been replenished, the operation of storing the plate 100 will stop.
