[0001] This utility model belongs to the field of conveying equipment technology, and particularly relates to a new trunk line conveying system. Background Technology
[0002] A restaurant is a facility or public dining establishment that provides food, beverages, and other catering services to the general public in a designated location.
[0003] To improve service efficiency, some restaurants have introduced Shinkansen conveyor systems. These systems use set delivery tracks and delivery carts to deliver food to customers, achieving unmanned delivery and improving work efficiency. However, when customers take food from the trays on the delivery carts, food and soup may spill onto the trays, requiring manual cleaning. Since the entire process is quite busy, spending time cleaning up can delay the work schedule.
[0004] Therefore, it is necessary to invent a new high-speed rail transport system to solve the above problems. Utility Model Content
[0005] To address the aforementioned problems, this utility model provides a new trunk line conveyor system to solve the issues raised in the background section.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a Shinkansen conveyor system, including a track, a conveyor car on the track, a carrier plate above the conveyor car, slide rods fixedly installed at the four corners of the bottom end of the carrier plate, a groove for cooperating with the slide rods on the top of the conveyor car, the bottom of the slide rods extending into the grooves, a spring sleeved on the outside of the slide rods, the two ends of the springs being fixedly connected to the carrier plate and the conveyor car respectively, side plates fixedly installed on both sides of the carrier plate, connecting frames rotatably installed on the inner side of the side plates, a first rotating rod and a second rotating rod respectively provided inside the two connecting frames, the first rotating rod and the second rotating rod being fixedly connected to the connecting frames by bolts, a rotating component for driving the rotation of the first rotating rod and a limiting component for limiting its rotation direction are provided on the outside of the connecting frame connecting the first rotating rod, a tablecloth is fixedly connected to the outside of the second rotating rod, the tablecloth is rolled up outside the second rotating rod, and the other end of the tablecloth is fixedly connected to the first rotating rod.
[0007] Furthermore, the rotating assembly includes a gear fixedly connected to one end of the connecting frame connected to the first rotating rod. A vertical plate is fixedly installed on the outer side of the conveyor. Connecting plates are fixedly installed at equal intervals from top to bottom on the outer side of the vertical plate. A rotating shaft is rotatably installed on the connecting plate. Teeth that mesh with the gear are fixedly sleeved on the outside of the rotating shaft. A protrusion is provided on the upper part of the teeth near the vertical plate. The bottom of the protrusion is provided with an arc surface. The protrusion contacts the vertical plate. A torsion spring is sleeved on the outside of the rotating shaft. The two ends of the torsion spring are fixedly connected to the rotating shaft and the connecting plate, respectively.
[0008] Furthermore, the limiting component includes ratchet teeth equidistantly arranged around the outside of the connecting frame connecting the first rotating rod, and a pawl that engages with the ratchet teeth is rotatably mounted on the inner side of the side plate.
[0009] Furthermore, one end of the connecting frame connected to the second rotating rod extends to the outside of the side plate and is fixedly connected to a frustum. A limit frame is fixedly installed on the outside of the conveyor, and the top of the limit frame is provided with an inclined surface. A rubber pad is fixedly installed on the inclined surface, and the rubber pad abuts against the outside of the frustum.
[0010] Furthermore, when the plate is placed on the carrier plate, the weight of the plate is sufficient to drive the carrier plate and the slide bar to overcome the spring force and descend to the bottom.
[0011] Furthermore, the tablecloth is a non-slip tablecloth.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] 1. This utility model enables the switching of tablecloths after the customer takes the plate, so that there is no need to spend time and effort cleaning the tablecloths during busy work, ensuring that the subsequent food delivery speed is not affected.
[0014] 2. By restricting the second rotating rod, this utility model can lock the tablecloth after the switching is completed. This prevents the tablecloth from being released from the second rotating rod when the waiter accidentally pulls it while placing the plate, thus ensuring that the tablecloth is laid flat. This prevents the tablecloth from wrinkling and affecting the stability of the plate when it is placed on it, ensuring that the plate is placed flat and that the subsequent transport is stable.

Detailed Implementation
[0023] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.
[0024] This utility model provides a new trunk line conveyor system, such as Figures 1 to 7 As shown, the system includes a track 1, on which a conveyor 2 is mounted. The track 1 and conveyor 2 are the track and conveyor 2 of a conventional Shinkansen intelligent conveyor system. A carrier plate 3 is mounted above the conveyor 2. Slide rods 4 are fixedly installed at the four corners of the bottom of the carrier plate 3. A groove is formed on the top of the conveyor 2 to mate with the slide rods 4. The bottom of the slide rods 4 extends into the groove. A spring 5 is fitted around the outside of the slide rods 4. Both ends of the spring 5 are fixedly connected to the carrier plate 3 and the conveyor 2, respectively. Side plates 6 are fixedly installed on both sides of the carrier plate 3. A connecting frame 7 is rotatably mounted on the inner side of the plate 6. The two connecting frames 7 are respectively provided with a first rotating rod 8 and a second rotating rod 10. The first rotating rod 8 and the second rotating rod 10 are fixedly connected to the connecting frame 7 by bolts 9. The connecting frame 7 connected to the first rotating rod 8 is provided with a rotating component for driving its rotation and a limiting component for limiting its rotation direction. A tablecloth 11 is fixedly connected to the outside of the second rotating rod 10. The tablecloth 11 is rolled up outside the second rotating rod 10, and the other end of the tablecloth 11 is fixedly connected to the first rotating rod 8.
[0025] In use, the waiter places the plate and food on the surface of the tablecloth 11 on the carrier plate 3. Under the action of gravity, the plate and food, along with the carrier plate 3 and the sliding rod 4, descend, compressing the spring 5 and causing it to deform and generate force. As the carrier plate 3 descends, it works in conjunction with the side plate 6 to lower the connecting frame 7, the first rotating rod 8, and the second rotating rod 10. The presence of the limiting component prevents the connecting frame 7 from reversing, so the tablecloth 11 will not be rolled up during the entire descent. Subsequently, the conveyor 2, along with the track 1, moves the plate and food to the customer. After the customer removes the plate and food, the compressed spring 5 releases its force, causing the carrier plate 3 to rise and reset. At this time, the rotating component drives the connecting frame 7 to rotate clockwise, thereby bringing the connecting... The first rotating rod 8 rotates clockwise, thereby rolling up the tablecloth 11. This causes the second rotating rod 10 to rotate and release the clean tablecloth 11. If a customer accidentally spills soup on the tablecloth 11, the rolling up of the tablecloth 11 will cause the soiled tablecloth 11 to be rolled up onto the surface of the first rotating rod 8. Finally, the clean tablecloth 11 is located on the surface of the carrier plate 3, completing the switching of the tablecloth 11. This eliminates the need for time-consuming and laborious cleaning of the tablecloth 11 during busy work, ensuring that the subsequent food delivery speed is not affected. At the end of the day's work, rotating the bolt 9 separates the first rotating rod 8 and the second rotating rod 10 from the connecting frame 7, allowing the tablecloth 11 to be removed along with the first rotating rod 8 and the second rotating rod 10 for washing.
[0026] like Figures 2 to 5 As shown, the rotating assembly includes a gear 12 fixedly connected to one end of the connecting frame 7 connected to the first rotating rod 8. A vertical plate 13 is fixedly installed on the outside of the conveyor 2. Connecting plates are fixedly installed on the outside of the vertical plate 13 at equal intervals from top to bottom. A rotating shaft 14 is rotatably installed on the connecting plate. Teeth 15 that mesh with the gear 12 are fixedly sleeved on the outside of the rotating shaft 14. A protrusion 17 is provided on the upper part of the tooth 15 near the vertical plate 13. The bottom of the protrusion 17 is provided with an arc surface. The protrusion 17 contacts the vertical plate 13. A torsion spring 16 is sleeved on the outside of the rotating shaft 14. The two ends of the torsion spring 16 are fixedly connected to the rotating shaft 14 and the connecting plate, respectively.
[0027] When the side plate 6 and connecting frame 7 descend, the gear 12 descends as well. After the gear 12 comes into contact with the tooth 15, the connecting frame 7 cannot reverse due to the presence of the limiting component. Subsequently, the descent of the gear 12 causes the tooth 15 to rotate downward with the protrusion 17, thereby rotating the shaft 14 and causing the torsion spring 16 to deform and generate force. When the gear 12 and tooth 15 separate, the torsion spring 16 rotates the shaft 14 and tooth 15 to reset. When the side plate 6 and connecting frame 7 rise, the gear 12 comes into contact with the tooth 15. Due to the presence of the protrusion 17, the tooth 15 cannot rotate upward and remains stationary. Subsequently, the gear 12 moves along the surface of the tooth 15 and rotates in the forward direction, thereby rotating the connecting frame 7 and the first rotating rod 8, thus driving the first rotating rod 8.
[0028] like Figures 4 to 5 As shown, the limiting component includes ratchet teeth 18 that are equidistantly arranged around the outside of the connecting frame 7 that connects to the first rotating rod 8, and a pawl 19 that engages with the ratchet teeth 18 is rotatably mounted on the inside of the side plate 6.
[0029] The ratchet tooth 18 and the pawl 19 work together to ensure that the connecting frame 7 can only rotate in the forward direction and cannot rotate in the reverse direction.
[0030] like Figures 6 to 7 As shown, one end of the connecting frame 7 connected to the second rotating rod 10 extends to the outside of the side plate 6 and is fixedly connected to a frustum 20. A limit frame 21 is fixedly installed on the outside of the conveyor 2. The top of the limit frame 21 is provided with an inclined surface, and a rubber pad 22 is fixedly installed on the inclined surface. The rubber pad 22 abuts against the outside of the frustum 20.
[0031] After the tablecloth 11 is switched, the rubber pad 22 is in contact with the truncated cone 20. Due to the friction between the rubber pad 22 and the truncated cone 20, the truncated cone 20 cannot rotate, thus preventing the second rotating rod 10 from rotating. The tablecloth 11 remains stationary. Therefore, if the waiter accidentally pulls on the tablecloth 11 when placing the plate, the tablecloth 11 will not fall off the second rotating rod 10, ensuring that the tablecloth 11 is laid flat. This prevents wrinkles from affecting the stability of the plate when it is placed on the tablecloth 11, ensuring that the plate is placed flat and that subsequent transport is stable. As the second rotating rod 10 descends, the truncated cone 20 disengages from the rubber pad 22. Therefore, when the second rotating rod 10 rises, it can rotate. When the second rotating rod 10 returns to its original position, the rubber pad 22 is in contact with the truncated cone 20, and the second rotating rod 10 cannot rotate.
[0032] like Figure 2 As shown, when the plate is placed on the carrier plate 3, the weight of the plate is sufficient to drive the carrier plate 3 and the slide bar 4 to overcome the elastic force of the spring 5 and descend to the bottom.
[0033] like Figure 2 As shown, tablecloth 11 is a non-slip tablecloth.
[0034] This allows the plates to be transported stably when placed on the tablecloth 11.
[0035] Working principle: During use, the waiter places the plate and food on the surface of the napkin 11 on the carrier plate 3. Under the action of gravity, the plate and food, along with the carrier plate 3 and the sliding rod 4, descend, compressing the spring 5 and causing it to deform and generate force. As the carrier plate 3 descends, the side plate 6, along with the connecting frame 7, the first rotating rod 8, and the second rotating rod 10, descend. The presence of the limiting component prevents the connecting frame 7 from reversing, so the napkin 11 will not be rolled up during the entire descent. When the side plate 6 and the connecting frame 7 descend, they cause the gear 12 to descend as well. After the gear 12 abuts against the teeth 15, the limiting component prevents the connecting frame 7 from reversing. Subsequently, the descent of the gear 12 causes the teeth 15 to rotate downwards, causing the protrusion 17 to rotate. The torsion spring 16, driven by the rotating shaft 14, undergoes torsional deformation to generate force. When the gear 12 separates from the tooth 15, the torsion spring 16 rotates the rotating shaft 14 and the tooth 15 back to their original position. Subsequently, the conveyor 2, in conjunction with the track 1, moves the tray and food to the customer. After the customer removes the tray and food, the compressed spring 5 releases its force, causing the carrier plate 3 to rise and return to its original position. The side plate 6 and the connecting frame 7 also rise. At this point, the gear 12 and the tooth 15 come into contact. Due to the presence of the protrusion 17, the tooth 15 cannot rotate upwards and remains stationary. Then, the gear 12 moves along the surface of the tooth 15, causing it to rotate in the forward direction. This rotates the connecting frame 7 and the first rotating rod 8, thereby rolling up the tablecloth 11. This causes the tablecloth 11 to pull the second rotating rod 1. Rotating the screw 9 releases the clean tablecloth 11. If a customer accidentally spills soup on the tablecloth 11, the cloth 11 will roll up onto the surface of the first rotating rod 8, leaving the clean tablecloth 11 on the carrier plate 3. This completes the switching of the tablecloth 11, eliminating the need for time-consuming and laborious cleaning during busy work hours and ensuring that subsequent food delivery speed is not affected. At the end of the day's work, rotating the screw 9 separates the first rotating rod 8 and the second rotating rod 10 from the connecting frame 7, allowing the tablecloth 11 to be removed along with the first rotating rod 8 and the second rotating rod 10 for washing. After the tablecloth 11 has been switched, the rubber pad 22 comes into contact with the frustum 20. Due to the friction between the rubber pad 22 and the frustum 20, the tablecloth 11... At this point, the pedestal 20 cannot rotate, thus preventing the second rotating rod 10 from rotating. The tablecloth 11 remains stationary. Therefore, if the waiter accidentally pulls on the tablecloth 11 while placing the plate, the tablecloth 11 will not fall off the second rotating rod 10, ensuring that the tablecloth 11 is laid flat. This prevents wrinkles from affecting the stability of the plate when it is placed on the tablecloth 11, ensuring that the plate is placed flat and that subsequent transport is stable. As the second rotating rod 10 descends, the pedestal 20 disengages from the rubber pad 22. Therefore, when the second rotating rod 10 rises, it can rotate on its own. When the second rotating rod 10 returns to its original position, the rubber pad 22 comes into contact with the pedestal 20, and the second rotating rod 10 cannot rotate at this point.
[0036] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
