Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of food delivery devices, and more specifically, to a chain-type circulating food delivery device. Background Technology

[0002] Food runners are a profession in hotels and restaurants. In the past, they were called "waiters". They are mainly responsible for delivering food to different stalls in the restaurant. Food runners are the bridge connecting the kitchen and the front of the house.

[0003] In the current technology, food runners usually carry the dishes from the kitchen to the front of the house themselves. After taking the dishes prepared in the kitchen, they carry the dishes to the front of the house on a first tray, and then the waiters carry the dishes to the guests' tables. However, with the development of the times, restaurant buildings are often built with many floors, and the restaurant and other floors are also high. This way of carrying dishes is relatively traditional, consumes a lot of manpower, and has low efficiency. Utility Model Content

[0004] To overcome the above-mentioned defects, embodiments of this disclosure provide a chain-type circulating food delivery device to solve the technical problems of the traditional use of manual food delivery in high-rise buildings, which consumes manpower and has low delivery efficiency.

[0005] According to one aspect, at least one embodiment of this disclosure provides a chain-type circulating food delivery device, including a support frame and a first tray. The support frame has multiple slots for placing prepared dishes on the first tray and facilitating their retrieval. It also includes multiple tray frames and a quick-release assembly. The multiple tray frames are disposed within the support frame via a transmission mechanism. Each tray frame has a locking groove that engages with the first tray. The top of each tray frame has a slot for receiving and conveying the first tray. When the first tray engages with the locking groove, dishes are placed on the first tray through the slot. The inner wall of the slot serves to limit the movement of the dishes, preventing them from slipping off the first tray. The quick-release assembly is disposed on the tray frame for locking the first tray.

[0006] To facilitate the repeated transport of food from the bottom to the top, the transmission mechanism includes two sets of sprockets, a first motor, two chains, and a connector. Each set of sprockets is rotatably connected to the inner wall of the support frame via a rotating shaft. Each set of sprockets includes a main sprocket and a secondary sprocket, located at the bottom and top of the support frame, respectively. The two sets of sprockets are respectively disposed on the two inner walls of the support frame, and are symmetrically arranged within the support frame with respect to the center. The first motor is mounted on the outer wall of the support frame, and its output end is coaxially connected to the main sprocket. The two chains are respectively fitted onto the main sprocket and the secondary sprocket at both ends of the support frame. The connector is disposed on the two chains and is used to horizontally connect the tray frame.

[0007] In order to secure the first pallet to the two chains and to maintain smooth transport when the two chains are conveying simultaneously, the connector includes two connecting seats, a fixed seat, and a connecting shaft. The two connecting seats are respectively fixedly connected to one end of the two chains, one end of the fixed seat is fixedly connected to the connecting seats, one end of the connecting shaft is rotatably connected to the fixed seat, and the other end of the connecting shaft is fixedly connected to both ends of the pallet frame.

[0008] To facilitate the disassembly and securing of the first tray and enable timely replacement of the first tray, the quick-release assembly includes a push plate, a push handle, and two insert rods. The push plate is set on the lower side of the tray frame via an elastic element. One end of the push handle is fixedly connected to the bottom end of the push plate. One end of each insert rod is fixedly connected to the top end of the push plate. The other end of each insert rod passes through the bottom end of the tray frame and is inserted into the bottom of the first tray. The bottom end of the tray frame has a through hole that mates with the insert rod. The first tray has an insertion hole that mates with the insert rod.

[0009] To elastically connect the push plate to the bottom of the tray frame and facilitate the disassembly of the first tray, the elastic element includes two connecting springs, a limiting rod, and a limiting plate. One end of each of the two connecting springs is fixedly connected to the top of the tray frame; the other end of each of the two connecting springs is fixedly connected to one end of the push plate; one end of the limiting rod is fixedly connected to the bottom of the tray frame, and the other end passes through the push plate; one end of the limiting plate is fixedly connected to the other end of the limiting rod.

[0010] In order to enable the pallet frame to be repeatedly transported under the drive of the two sets of sprockets and the two chains, the two connecting seats are respectively located at two diagonal corners of the pallet frame, and the two connecting seats are on the same horizontal line.

[0011] In order to place the food on the first tray and to limit the food's position with the tray frame, the snap-fit ​​groove is connected to the empty slot, and the cross-sectional area of ​​the snap-fit ​​groove is larger than the cross-sectional area of ​​the empty slot.

[0012] To enable the pallet frame to move smoothly longitudinally, the main sprocket and the auxiliary sprocket have the same diameter and their center points are in the same vertical direction.

[0013] The beneficial effects of the embodiments disclosed herein are as follows:

[0014] 1. In this disclosure, by providing a quick-release component, pulling down the push handle drives one end of the two insert rods out of the insertion hole and the through hole, inserting the first tray into the snap-fit ​​groove. Releasing the push handle, the elastic force of the connecting ring contraction drives the insert rod to pass through the through hole and insert into the insertion hole, thus completing the replacement and fixing of the first tray. After the first tray is used, a new first tray can also be replaced in time, which is convenient for operation.

[0015] 2. In this disclosure, by setting up a transmission mechanism, two first motors are started simultaneously. The first motors drive the tray frame and the first tray to carry the dishes in a horizontal state as they are circulated along the chain. When the dishes are transported to the corresponding slot, the two first motors can be temporarily stopped and the dishes can be taken out. Then the subsequent dishes are circulated and transported. This way, the food delivery can save manpower and time and is more convenient. Attached Figure Description

[0028] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0029] like Figures 1-5 As shown, it illustrates a chain-type circulating food delivery device in one embodiment of the present disclosure, which solves the technical problems of the traditional use of manual food delivery in high-rise buildings, which consumes manpower and has low delivery efficiency.

[0030] According to one aspect, at least one embodiment of the present disclosure provides a chain-type circulating food delivery device, including a support frame 1 and a first tray 2, one end of the first tray 2 is provided with a pull handle, characterized in that the support frame 1 is provided with a plurality of slots 3 for placing the prepared food on the first tray 2 and for easy access to the food, and also includes a plurality of tray frames 4 and quick-release components.

[0031] like Figure 1 , Figure 2 and Figure 3As shown, multiple tray frames 4 are all mounted within the support frame 1 via a transmission mechanism. Each tray frame 4 has a locking groove 5 that engages with the first tray 2. The top of each tray frame 4 has a slot 6 for receiving and transporting the first tray 2. To allow food to be placed on the first tray 2 and to help the tray frame 4 limit the food's movement, the locking groove 5 connects to the slot 6. The cross-sectional area of ​​the locking groove 5 is larger than that of the slot 6. When the first tray 2 is engaged into the locking groove 5, food is placed on the first tray 2 via the slot 6. The inner wall of the slot 6 also helps to limit the food's movement, preventing it from slipping off the first tray 2. To facilitate the repeated transport of food from the tray to higher levels, the transmission mechanism includes two sets of sprockets and a first motor. 10. Two chains 11 and connecting parts. Each set of sprockets is rotatably connected to the inner wall of the support frame 1 via a rotating shaft 7. Each set of sprockets includes a main sprocket 8 and a secondary sprocket 9, located at the bottom and top of the support frame 1 respectively. To ensure smooth longitudinal movement of the pallet frame 4, the main sprocket 8 and the secondary sprocket 9 have the same diameter and their center points are in the same vertical direction. The two sets of sprockets are respectively set on the two inner walls of the support frame 1, and are symmetrically arranged within the support frame 1 with respect to the center of the support frame 1. A first motor 10 is mounted on the outer wall of the support frame 1, and the output end of the first motor 10 is coaxially connected to the main sprocket 8. The two chains 11 are respectively fitted onto the main sprocket 8 and the secondary sprocket 9 at both ends of the support frame 1. Connecting parts are provided on both sides. On each chain 11, a pallet frame 4 is horizontally connected. To fix the first pallet 2 onto the two chains 11 and to maintain smooth conveying when both chains 11 are conveying simultaneously, the connector includes two connecting seats 12, a fixed seat 13, and a connecting shaft 14. The two connecting seats 12 are fixedly connected to one end of each of the two chains 11. To allow the pallet frame 4 to be repeatedly conveyed under the drive of the two sets of sprockets and the two chains 11, the two connecting seats 12 are located at two diagonally opposite corners of the pallet frame 4 and are on the same horizontal line. One end of the fixed seat 13 is fixedly connected to the connecting seat 12, and one end of the connecting shaft 14 is rotatably connected to the fixed seat 13. The other end of the connecting shaft 14 is fixedly connected to both ends of the pallet frame 4. Two first motors 10 are started. The output of the first motor 10 rotates, driving the rotating shaft 7 to rotate. The rotating shaft 7 rotates, driving the main sprocket 8 to rotate. The rotating main sprocket 8 drives the chain 11, which in turn drives the auxiliary sprocket 9 to rotate. The chain 11 drives the connecting seat 12, which in turn drives the fixed seat 13. Because the two rotating shafts 7 keep the pallet frame 4 horizontal and the pallet frame 4 has its own weight, the pallet frame 4 is moved along with the chain 11. After the pallet frame 4 is moved longitudinally, when the chain 11, which is in contact with the connecting seat 12, passes the sprocket, the connecting shaft 14 rotates to keep the pallet frame 4 horizontal. Subsequently, the pallet frame 4 will change horizontally during the conveying process.This ensures that tray frame 4 is always cyclically conveyed with its top facing upwards;

[0032] like Figure 4 and Figure 5 As shown, a quick-release assembly is installed on the tray frame 4 to lock the first tray 2. To facilitate the disassembly and securing of the first tray 2 and allow for timely replacement, the quick-release assembly includes a push plate 15, a push handle 16, and two insert rods 17. The push plate 15 is elastically mounted on the lower side of the tray frame 4. One end of the push handle 16 is fixedly connected to the bottom end of the push plate 15. One end of each insert rod 17 is fixedly connected to the top end of the push plate 15, and the other end of each insert rod 17 passes through the bottom end of the tray frame 4 and inserts into the bottom of the first tray 2. The bottom end of frame 4 has a through hole 18 that mates with the insert rod 17, and the first tray 2 has an insert hole 19 that mates with the insert rod 17. In order to elastically connect the push plate 15 to the bottom end of the tray frame 4 and facilitate the disassembly of the first tray 2, the elastic components include two connecting springs 20, a limiting rod 21, and a limiting plate 22. One end of each of the two connecting springs 20 is fixedly connected to the top end of the tray frame 4; the other end of each of the two connecting springs 20 is fixedly connected to one end of the push plate 15, and one end of the limiting rod 21 is fixedly connected to the bottom end of the tray frame 4. The other end passes through the push plate 15. One end of the limiting plate 22 is fixedly connected to the other end of the limiting rod 21. By pulling down the push handle 16, the push plate 15 is moved downward. The push plate 15 moves one end of the connecting spring 20 downward, and the connecting spring 20 extends. The limiting rod 21 guides the connecting spring 20, allowing the connecting spring 20 to stretch longitudinally. The push plate 15 simultaneously moves the two insert rods 17 downward. One end of the two insert rods 17 moves out of the insertion hole 19 and the through hole 18. Then, by pulling the pull handle, the first tray 2 is moved from... The first tray 2 moves within the snap-fit ​​groove 5. By releasing the push handle 16, the elastic force of the connecting spring 20 drives the two insert rods 17 to be inserted into the insertion hole 19. This allows the used first tray 2 to be removed and replaced by the cleaning machine. When the first tray 2 needs to be replaced, pull down the push handle 16 to move the insert rods 17 out of the tray frame 4 and insert the new first tray 2 into the snap-fit ​​groove 5. Release the push handle 16, and use the elastic force of the connecting ring to drive the insert rods 17 through the through hole 18 and into the insertion hole 19. This completes the replacement and fixing of the first tray 2.

[0033] Working Principle: A chain-type circulating food delivery device is applied to a suitable location. Before using the device, pulling down the push handle 16 moves the push plate 15 downwards. The push plate 15 moves one end of the connecting spring 20 downwards, extending the connecting spring 20. The limiting rod 21 guides the connecting spring 20, allowing it to stretch longitudinally. Simultaneously, the push plate 15 moves two insert rods 17 downwards, with one end of each rod moving out of the insertion hole 19 and through hole 18. The first tray 2 is then inserted into the locking groove 5. Releasing the push handle 16 allows the elastic force of the connecting ring to drive the insert rods 17 through the through hole 18 and into the insertion hole 19, thus completing the replacement and fixing of the first tray 2. The food is then placed on the first tray 2 through the slot 3, in the same position as the outside world through the slot 6. Subsequently, both first motors 10 are started simultaneously, and the output ends of the first motors 10 rotate. The rotating shaft 7 rotates, which drives the main sprocket 8 to rotate. The main sprocket 8 then drives the chain 11, which in turn drives the secondary sprocket 9. The chain 11 drives the connecting seat 12, which in turn drives the fixed seat 13. This causes the tray frame 4 and the first tray 2 to continuously transport the food along the chain 11 while maintaining a horizontal position. When the food reaches the corresponding slot 3, the two first motors 10 can be temporarily stopped, the food can be removed, and then the subsequent food can be transported in a continuous cycle. This method of food transport saves manpower and time and is more convenient. After the food transport is completed, there may be some spilled soup on the first tray 2. This can be removed by pulling down the push handle 16 to move the insert rod 17 out of the tray frame 4. The used first tray 2 can then be removed for cleaning, and a new first tray 2 can be replaced in time, making the operation convenient.
