Description

Technical Field

[0001] This utility model relates to the field of intelligent food delivery equipment technology, and in particular to a stop device and a conveying device. Background Technology

[0002] In modern restaurants, canteens, and hotels, automated food delivery systems are widely used to improve efficiency and reduce labor costs. A typical food delivery system consists of a first conveyor belt that connects to the kitchen and a second conveyor belt that connects to the dining tables. The kitchen places prepared meals on the first conveyor belt and controls the food dispensing via a control panel. The first conveyor belt then transports the meals to the second conveyor belt, and finally, the second conveyor belt delivers the meals to the designated tables.

[0003] During the food transport process, food items on the second conveyor belt that are located at designated tables may not have been removed yet, even though the kitchen has already placed prepared food items on the first conveyor belt for transport. To prevent the kitchen-prepared food items from being directly transported away from the designated tables, a barrier device is usually installed between the first and second conveyor belts. This barrier device is typically driven by a motor or cylinder to raise (allow) and lower (block) the food items on the transport path (i.e., the transport path of the first and second conveyor belts).

[0004] For example, when the food on the second conveyor belt has not yet been removed, the barrier mechanism drops and is placed between the first and second conveyor belts to block the food, preventing it from being transferred to the second conveyor belt, and thus the second conveyor belt does not move.

[0005] However, existing stop bar devices are prone to significant gap changes between their ends and the mounting housing during rotation. For example, when the stop bar is lowered, a large gap is required between its end and the mounting housing so that the outer surface of the stop bar can fit snugly against the housing when it is raised. Furthermore, the traditional stop bar structure is often not compact enough, occupying considerable installation space and hindering the overall structural optimization of the conveying equipment.

[0006] Therefore, those skilled in the art are dedicated to developing a compact stop device in which the gap between the stop and the mounting housing remains almost unchanged regardless of whether the stop is raised or lowered. Utility Model Content

[0007] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is how to prevent the gap between the stop bar and the mounting housing of the conveying equipment from remaining unchanged when the stop bar device is raised or lowered, while also making the overall structure of the conveying equipment more compact.

[0008] To achieve the above objectives, this utility model provides a stop bar device, installed on a conveying equipment, comprising: A rod body, the rod body including a connecting part and a blocking part, the thickness of the connecting part being less than the thickness of the blocking part, the connecting part having a starting end and a first connecting end disposed opposite to each other, and the blocking part being connected to the first connecting end; A rotating component, which is connected to the connecting portion and is configured to rotate around a rotation center point under the action of an external force, so as to drive the connecting portion and the blocking portion to rotate; The rotating component and the connecting part have a connection point, the connection point and the starting end have a first distance, the connection point and the first connecting end have a second distance, the rotation center point and the connection point have a rotation radius, the ratio of the rotation radius to the first distance is greater than or equal to 0.9 and less than 1, and the ratio of the rotation radius to the second distance is greater than or equal to 0.9 and less than or equal to 1.

[0009] In one embodiment, the rotating member includes a first rotating body, a first end of which is connected to the connecting portion to have the connecting point, and a second end of which is connected to the conveying device via a rotating shaft to have the rotation center point.

[0010] In one embodiment, the rotating component further includes a second rotating body, the second rotating body having a docking end and a counterweight end disposed opposite to each other, the docking end being connected to the second end of the first rotating body; The second rotating body and the first rotating body form a first included angle, which is greater than 0° and less than 180°.

[0011] In one embodiment, the first included angle is greater than 30° and less than 150°.

[0012] In one embodiment, the first included angle is 90°.

[0013] In one embodiment, the stop device further includes a counterweight connected to the counterweight end of the second rotating body, and the weight of the counterweight is less than the weight of the rod.

[0014] In one embodiment, the ratio of the weight of the counterweight to the weight of the rod is greater than 0.7 and less than or equal to 1.

[0015] In one embodiment, the stop device further includes a drive member connected to the rotating member and configured to drive the rotating member to rotate.

[0016] This utility model also provides a conveying device, including: A conveying device configured to convey a target object, and the conveying device having a conveying surface for placing the target object; A housing, the housing being disposed on both sides of the conveying device, and the housing having mounting grooves; and A stop lever device, which is mounted in the mounting slot and configured to rotate relative to the housing; The stop lever device is the stop lever device described above.

[0017] In one embodiment, the stop device rotates relative to the housing to have a blocking state and a yielding state; When in the blocking state, the rod of the blocking device is positioned close to the conveying surface and parallel to the conveying surface, so as to cut off the target object along the conveying path of the conveying surface; When in the avoidance state, the rod of the stop device is positioned away from the conveying surface, and the distance between the edge of the target object and any point on the rod is greater than 0.

[0018] In one embodiment, when the stop device is in the avoidance state, the rod body and the conveying surface have a second included angle, the second included angle being greater than or equal to 45° and less than 180°.

[0019] In one embodiment, the second included angle is 90°.

[0020] In one embodiment, when the stop device is in a blocking state, there is a first gap between the starting end of the connecting part of the rod and the housing; When the stop bar device is in the avoidance state, there is a second gap between the first surface of the connecting part of the bar and the housing. Wherein, the first gap is less than or equal to a preset value, the second gap is less than or equal to the preset value, and the preset value ranges from greater than or equal to 0 cm to less than or equal to 0.5 cm.

[0021] In one embodiment, the preset value range is greater than or equal to 0.1 cm and less than or equal to 0.3 cm.

[0022] In one embodiment, when the stop device is in the avoidance state, there is a third distance between the first connecting end of the connecting part and the outer surface of the housing, and the third distance is greater than or equal to 0.

[0023] In one embodiment, the conveying device further includes a first detection element mounted on the housing and located on one side of the stop device, the first detection element being configured to detect the state of the stop device; When the distance between the first detection element and the stop device is less than or equal to a preset distance, the first detection element can detect the stop device, and the stop device is in a blocking state. When the distance between the first detection element and the stop device is greater than a preset distance, the first detection element does not detect the stop device, and the stop device is in an avoidance state.

[0024] The stop bar device provided by this utility model has the following technical effects: by setting the ratio of the rotation radius to the first gap and the second gap between 0.9 and 1, the first gap between the starting end of the connecting part and the housing of the conveying equipment changes very little during the rotation of the bar body, and the second gap between the first surface of the connecting part and the housing of the conveying equipment changes very little. The first gap and the second gap are always controlled within a very small preset value, so that this "approximate fit" motion trajectory fundamentally eliminates the large risk of pinching injury present in traditional stop bars and greatly improves the safety of equipment operation. Furthermore, by setting the ratio of the rotation radius to the first and second distances between 0.9 and 1, the lever arm relationship can be optimized when the rotating component drives the rod to rotate, effectively reducing the output torque required by the drive component that drives the rotating component. This allows the use of a drive component with lower power and lower cost, thereby achieving energy saving and consumption reduction. Meanwhile, the counterweights can balance part of the weight of the rod, further reducing the driving force required and making the movement smoother.

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0028] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the illustrations only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0029] Some exemplary embodiments of the present invention have been described for illustrative purposes. It should be understood that the present invention may be implemented in other ways not specifically shown in the accompanying drawings.

[0030] like Figures 1 to 11 As shown, in a preferred embodiment of this utility model, the conveying device 100 is suitable for conveying the target item 200 from the self-prepared food area to the dining area. In this embodiment, the target item 200 is a meal, i.e., a plate containing food. The food preparation area is the kitchen, and the dining area is where customers eat. The meals prepared in the self-prepared food area can be delivered by the food delivery system to each customer's seat in the dining area.

[0031] The conveying device 100 can be signal-connected to a control device to control the conveying operation of the conveying device 100. The operation of the control device can be controlled using a control circuit. The control circuit may include storage and processing circuitry for controlling system operations. The circuitry may include storage devices, such as hard disk drive storage devices, non-volatile memory (e.g., electrically programmable read-only memory configured to form a solid-state drive), volatile memory (e.g., static or dynamic random access memory), etc. The circuitry in the control circuitry may be based on one or more microprocessors, microcontrollers, digital signal processors, baseband processors, power management units, audio chips, graphics processing units, application-specific integrated circuits (ASICs), and other integrated circuits. Software code (instructions) may be stored in the circuit memory and executed on the processing circuitry in the circuitry to perform system operations (e.g., data collection operations, operations involving adjusting components using control signals, image rendering operations generating image content to be displayed to the user, etc.).

[0032] If needed, the control device may include wireless circuitry and / or other circuitry to support communication with a computer or other external devices (e.g., providing displayable computer and image content). During operation, the control circuitry can provide image content to be displayed. The content may be remotely received (e.g., from a computer or other content sources coupled to the system) and / or may be generated by the control circuitry (e.g., text, other computer-generated content, etc.). The displayed content is provided by the control circuitry so that the viewer can view it at a window.

[0033] In this embodiment, an operation panel can be provided in the food preparation area. The operation panel integrates control devices, which are then connected to the conveying device 100 via signal. When food needs to be delivered, the target item 200 is set to the designated location on the operation panel and then placed on the conveying device 100.

[0034] The conveying equipment 100 includes a conveying device 102 and a housing 101. The conveying device 102 is configured to convey a target object 200 and has a conveying surface 1023 for placing the target object 200. The conveying device 102 includes a first conveying mechanism 1021 that interfaces with a food preparation area and a second conveying mechanism 1022 that interfaces with a dining area. The first conveying mechanism 1021 and the second conveying mechanism 1022 are connected to each other so that food from the food preparation area can be conveyed from the first conveying mechanism 1021 to the second conveying mechanism 1022 and then conveyed by the second conveying mechanism 1022 to a designated location in the dining area, whereby customers can pick up the corresponding target object 200.

[0035] The first conveying mechanism 1021 and the second conveying mechanism 1022 can both operate independently, that is, the first conveying mechanism 1021 and the second conveying mechanism 1022 can operate synchronously, or one of the first conveying mechanism 1021 and the second conveying mechanism 1022 can operate.

[0036] The first conveying mechanism 1021 and the second conveying mechanism 1022 have the same structure, both including a drive motor, a roller connected to the drive motor, and a conveyor belt wound around the roller. The drive motor drives the roller to rotate, which in turn drives the conveyor belt to rotate, thereby realizing the conveying of the target object 200. The upper surface of the conveyor belt is the conveying surface 1023 for placing and conveying the target object 200.

[0037] The housing 101 is disposed on both sides of the conveying device 102, and the height of the housing 101 is greater than the height of the conveying device 102. This allows the housing 101 to block the drive motor, rollers and other objects of the conveying device 102 while preventing the target object 200 on the conveying surface 1023 from falling off one side of the conveying surface 1023.

[0038] As described above, the target item 200 is transported from the food preparation area to a designated location in the dining area via the first conveyor 1021 and the second conveyor 1022. When the target item 200 on the second conveyor 1022 has not yet been retrieved, a new target item 200 is placed on the first conveyor 1021 in the food preparation area. At this time, the first conveyor 1021 transports the new target item 200 to the second conveyor 1022. To prevent the second conveyor 1022 from receiving the new target item 200 and transferring it, thus causing the unretrieved target item 200 originally located in the designated location to be directly transported away from the designated location, a baffle device 300 is usually installed. The baffle device 300 can temporarily block the first conveyor 1021 from receiving the new target item 200, thereby preventing the second conveyor 1022 from receiving it. In this embodiment, the baffle device 300 is located on the side of the second conveyor 1022 closest to the first conveyor 1021. In other embodiments, the stop device 300 may also be disposed between the first conveying mechanism 1021 and the second conveying mechanism 1022. No specific limitation is made here, but it depends on the actual situation.

[0039] The stop lever device 300 is mounted on the housing 101. Correspondingly, the housing 101 has a mounting groove 1011, in which the stop lever device 300 is mounted and configured to rotate relative to the housing 101. In this embodiment, the stop lever device 300 is mounted in the mounting groove 1011 via a mounting base 106. The mounting base 106 can be fixedly connected to the housing 101, or it can be fixedly connected to the second conveying mechanism 1022; no specific limitation is made here, and it depends on the actual situation.

[0040] When the stop lever device 300 rotates downward and is positioned horizontally between the first conveying mechanism 1021 and the second conveying mechanism 1022, the stop lever device 300 blocks the conveying path of the target object 200 on the second conveying mechanism 1022, and the stop lever device 300 is in a blocking state. When the stop lever device 300 rotates upward until it is raised vertically upward, the stop lever device 300 avoids the conveying path of the target object 200 on the second conveying mechanism 1022, and the stop lever device 300 is in an avoiding state. Thus, the stop lever device 300 rotates relative to the housing 101 to have both a blocking state and an avoiding state.

[0041] The stop lever device 300 includes a lever body 1 and a rotating component 2 connected to the lever body 1. The lever body 1 is rod-shaped, and the rotating component 2 can rotate around the rotation center point 211 under the action of an external force, thereby driving the lever body 1 to rotate. The rotating component 2 is rotatably connected to the housing 101 through a rotating shaft 105, and the central axis of the rotating shaft 105 is the rotation center point 211 of the rotating component 2. That is, the rotating component 2 achieves rotation through the rotating shaft 105.

[0042] The aforementioned external force can be human force, that is, by applying force to the rotating shaft 105 by human intervention, the rotating shaft 105 is driven to rotate, which in turn drives the rotating component 2 to rotate.

[0043] Alternatively, the aforementioned external force is a mechanical force, that is, by providing a driving component 4, the driving component 4 is connected to the rotating shaft 105 to drive the rotating shaft 105 to rotate, thereby driving the rotating component 2 to rotate.

[0044] In this embodiment, to improve conveying efficiency, the aforementioned external force is mechanical force. Accordingly, the driving component 4 is a drive motor, which is signal-connected to the aforementioned control device. The control device is equipped with a corresponding driver program for the driving component 4, which drives the rotating component 2 to rotate by a preset angle, thereby improving the corresponding conveying efficiency.

[0045] Furthermore, a second detection element 103 can be provided on the rod body 1, facing the second conveying mechanism 1022. This second detection element 103 can detect whether the target object 200 is present on the second conveying mechanism 1022. The second detection element 103 is signal-connected to the control device, transmitting corresponding detection signals to the control device. The control device receives the detection signals and controls the stop device 300, the first conveying mechanism 1021, and the second conveying mechanism 1022 to perform corresponding actions based on different detection signals.

[0046] For example, under normal conditions, the stop device 300 is in a blocking state. At this time, if the second detection element 103 detects that there is still a target object 200 on the second conveying mechanism 1022, then when a new target object 200 is placed on the first conveying mechanism 1021 and transported to the second conveying mechanism 1022 via the first conveying mechanism 1021, the second conveying mechanism 1022 remains in a stopped state, and the stop device 300 remains in a blocking state. When the target object 200 on the second conveying mechanism 1022 is removed, and the second detection element 103 does not detect the presence of a target object 200 on the second conveying mechanism 1022, the stop device 300 rises, the second conveying mechanism 1022 switches from a stopped state to a running state, receives the new target object 200 from the first conveying mechanism 1021, and transports the new target object 200 to the corresponding designated position.

[0047] The second detection element 103 can be an infrared sensor or a laser sensor, etc., without specific limitations, depending on the actual situation.

[0048] As described above, the stop device 300 blocks the conveying path of the target object 200 on the second conveying mechanism 1022, and the stop device 300 is in a blocking state. When the stop device 300 rotates upward until it is raised to a vertical position, the stop device 300 avoids the conveying path of the target object 200 on the second conveying mechanism 1022, and the stop device 300 is in an avoiding state. That is, when the stop device 300 is in the blocking state, the rod 1 is positioned close to the conveying surface 1023 (the conveying surface 1023 of the second conveying mechanism 1022) and parallel to the conveying surface 1023, so as to cut off the target object 200 along the conveying path of the conveying surface 1023 (as shown by arrow a in the figure); when in the avoidance state, the rod 1 of the stop device 300 is positioned away from the conveying surface 1023, and the distance between the edge of the target object 200 and any point of the rod 1 is greater than 0, so as to prevent the rod 1 from contacting the target object 200 and hindering the target object 200 from being conveyed when the stop device 300 is in the avoidance state.

[0049] In other words, when the stop device 300 is in the avoidance state, there is a second included angle between the rod 1 and the conveying surface 1023, which is greater than or equal to 45° and less than 180°. Preferably, the second included angle is 90°. At this time, it is possible to avoid contact between the rod 1 and the target object 200, and also to avoid a gap between the starting end 121 of the rod 1 (described in detail below) and the housing 101.

[0050] The rod 1 includes a connecting portion 12 connected to the rotating member 2 and a blocking portion 11. The connecting portion 12 has a starting end 121 and a first connecting end 122 disposed opposite to each other, and the blocking portion 11 is connected to the first connecting end 122. In the prior art, the connecting portion 12 and the blocking portion 11 have the same thickness, and the rotating member 2 is not connected to the starting end 121 of the connecting portion 12 (which would increase the pressure of the output torque of the driving member 4). As a result, when the stop rod device 300 is in the blocking state, there is a gap between the starting end 121 of the connecting portion 12 and the housing 101. When the stop rod device 300 rotates to switch from the blocking state to the avoidance state, the outer surface of the connecting portion 12 contacts the housing 101. That is, the gap is actually set so as not to hinder the rotation of the rod 1. In this embodiment, the distance of the gap is greater than or equal to 3cm.

[0051] To prevent the aforementioned gaps from appearing, the thickness of the connecting part 12 in this embodiment is less than the thickness of the blocking part 11, thereby forming a clearance area on the outer surface of the rod 1, making the space required for the connecting part 12 to rotate smaller, while ensuring that the blocking part 11 has sufficient strength and rigidity to block the target object 200.

[0052] When the stop device 300 is in the blocking state, there is a first gap between the starting end 121 of the connecting portion 12 of the rod 1 and the housing 101; when the stop device 300 is in the yielding state, there is a second gap between the first surface of the connecting portion 12 of the rod 1 and the housing 101; wherein the first gap is less than or equal to a preset value, and the second gap is less than or equal to a preset value, the preset value range being greater than or equal to 0 cm and less than or equal to 0.5 cm. That is, regardless of whether the stop device 300 is in the blocking state or the yielding state, the rod 1 and the housing 101 are almost in contact. Preferably, the preset value range is greater than or equal to 0.1 cm and less than or equal to 0.3 cm. In this embodiment, the first gap and the second gap are equal to the thickness of the housing, both being 0.1 cm.

[0053] Furthermore, when the stop device 300 is in the avoidance state, there is a third distance between the first connecting end 122 of the connecting part 12 and the outer surface of the housing 101. The third distance is greater than or equal to 0 to ensure that there is no interference between the rod 1 and the housing 101.

[0054] Furthermore, the rotating component 2 and the connecting part 12 have a connection point 212, a first distance L2 between the connection point 212 and the starting end 121, a second distance L3 between the connection point 212 and the first connecting end 122, and a rotation radius L1 between the rotation center point 211 and the connection point 212. The ratio between the rotation radius L1 and the first distance L2 is greater than or equal to 0.9 and less than 1, and the ratio between the rotation radius L1 and the second distance L3 is greater than or equal to 0.9 and less than or equal to 1. This ratio relationship, close to 1, constrains the movement trajectory of the starting end 121 of the connecting part 12 and the first surface when the rod 1 rotates, resulting in minimal change in the gap between it and the housing 101.

[0055] The rotating component 2 includes a first rotating body 21, the first end of which is connected to the connecting part 12 to have a connection point 212, and the second end of which is connected to the mounting base 106 of the conveying device 100 via a rotating shaft 105 to have a rotation center point 211. The rotating component 2 also includes a second rotating body 22, which has a docking end and a counterweight end 221 arranged opposite to each other, and the docking end is connected to the second end of the first rotating body 21; wherein, a first included angle is formed between the second rotating body 22 and the first rotating body 21, the first included angle being greater than 0° and less than 180°. Preferably, the first included angle is greater than 30° and less than 150°. More preferably, the first included angle is 90°, which makes the rotating component 2 cleverly connected to the rod body 1, making the entire stop device 300 structure very compact, and can be installed in the narrow mounting slot 1011 of the housing 101, which is beneficial to the overall miniaturization and modular design of the conveying device 100.

[0056] The stop device 300 also includes a counterweight 3, which is connected to the counterweight end 221 of the second rotating body 22, and the weight of the counterweight 3 is less than the weight of the rod 1. In this embodiment, the ratio of the weight of the counterweight 3 to the weight of the rod 1 is greater than 0.7 and less than or equal to 1, in order to balance part of the weight of the rod 1, further reduce the driving force requirement, and make the movement more stable. In this embodiment, the counterweight 3 is an iron block, which is fixedly connected to the rotating body 2 by welding, bonding, or other methods. The counterweight 3 is installed at the counterweight end 221 of the second rotating body 22. In this embodiment, the counterweight 3 and the rod 1 are located on opposite sides of the second rotating body 22.

[0057] The conveying device 100 also includes a first detection element 104, which is mounted on the mounting base 106. The first detection element 104 is configured to detect the state of the stop device 300. Specifically, when the distance between the first detection element 104 and the stop device 300 is less than or equal to a preset distance, the first detection element 104 detects the stop device 300, and the stop device 300 is in a blocking state; when the distance between the first detection element 104 and the stop device 300 is greater than the preset distance, the first detection element 104 does not detect the stop device 300, and the stop device 300 is in a yielding state. In this embodiment, the first detection element 104 is a proximity sensor, positioned close to the counterweight 3, and the preset distance is 2mm. In other embodiments, the preset distance may be other values, such as 1mm or 3mm, etc., and is not specifically limited here, depending on the actual situation.

[0058] That is, when the stop device 300 is in the blocking state, the rod body 1 is arranged parallel to the conveying surface 1023, and at this time, the counterweight end 221 of the second rotating body 22 is positioned close to the first detection element 104. Correspondingly, the counterweight 3 is also positioned close to the first detection element 104. The first distance b between the counterweight 3 and the detection end of the first detection element 104 is 1mm, and the first detection element 104 can detect the stop device 300.

[0059] When the rotating member 2 rotates, causing the stop device 300 to switch from the blocking state to the avoidance state, the counterweight end 221 of the second rotating body 22 rotates away from the first detection member 104. At this time, the starting end 121 of the connecting part 12 rotates to the vicinity of the first detection member 104, that is, the starting end 121 of the connecting part 12 is positioned close to the first detection member 104. The second distance c between the starting end 121 of the connecting part 12 and the first detection member 104 is 4mm, and the first detection member 104 cannot detect the stop device 300. The state 300 of the stop device can be determined by whether the first detection member 104 can detect the stop device 300.

[0060] In summary: by setting the ratio of the rotation radius L1 to the first spacing L2 and the second spacing L3 between 0.9 and 1, the first gap between the starting end 121 of the connecting part 12 and the housing 101 of the conveying device 100 changes very little during the rotation of the rod 1, and the second gap between the first surface of the connecting part 12 and the housing 101 of the conveying device 100 changes very little. The first gap and the second gap are always controlled within a very small preset value, so that this "approximate fit" motion trajectory fundamentally eliminates the large risk of pinching that exists in traditional stop bars, and greatly improves the safety of equipment operation. Furthermore, by setting the ratio of the rotation radius L1 to the first spacing L2 and the second spacing L3 between 0.9 and 1, the lever arm relationship can be optimized when the rotating component 2 drives the rod 1 to rotate, which effectively reduces the output torque required by the driving component 4 that drives the rotating component 2 to rotate. A driving component 4 with lower power and lower cost can be used, thereby achieving energy saving and consumption reduction. Meanwhile, the counterweight 3 can balance part of the weight of the rod 1, further reducing the driving force requirement and making the movement more stable.
