Description

Liquid overflow prevention system and food transport equipment applying the same

The present invention relates to a liquid overflow prevention system of a food transport device, and more particularly, when a food transport device (eg, a serving robot) serves food, particularly liquids such as beverages or soups, speed changes or irregularities, etc. It relates to a technical idea that can prevent the liquid being served from overflowing from the container.

With the development of autonomous driving and robot technology, research is being actively conducted to serve food as a serving robot in stores such as restaurants.

Serving robots drive along a set route in a store on behalf of humans, or recognize obstacles on the driving route, load cooked food, and serve customers.

However, the serving robot serves the determined route at a set speed regardless of the type or characteristics of the loaded food. Alternatively, if there are irregularities or curves on the floor during movement, liquid overflow may occur due to inertia of the load (liquid overflows out of the container) or vibration of the serving robot itself (vibration due to irregularities).

1 and 2 are diagrams for explaining a case in which a liquid flow overflows in a conventional serving robot.

Referring to FIG. 1 , a predetermined food transport device 100 may load a container 10 containing liquid food and drive. In this case, the food transport device 100 may be a serving robot.

When the food transport device 100 reduces the speed while driving or, conversely, when a change in acceleration occurs, such as when the food transport device 100 starts moving while stopped, the container 10 loaded on the food transport device 100 due to inertia. Liquids contained in the chamber may overflow to the outside as they are drawn in one direction.

Also, as shown in FIG. 2 , when there are irregularities on the ground on which the food transport device 100 travels, the liquid flow may overflow out of the container 10 due to vibration generated while the food transport device 100 passes through the irregularities. can

In order to solve this problem, in general, the food transport device 100, in particular, the food transport device 100 such as a serving robot that performs autonomous driving, prevents the loading of loads due to inertia to some extent through acceleration control. In this case, there is a problem that the serving speed may be lowered, and even if the acceleration control is performed, the vibration caused by the unevenness of the ground cannot be eliminated, so there may still be a risk that the liquid food overflows out of the container 10 .

In addition, in the case of a transport device that serves food through autonomous driving, such as such a serving robot, as well as a transport device that is directly operated by a person (employee), for example, a cart-type transport device, a loading phenomenon due to inertia or unevenness of the ground The overflow of liquid food may occur due to the vibration caused by the vibration, so special attention is required.

Accordingly, there is a need for a technical idea capable of effectively preventing the loaded food from overflowing even when the food transport mechanism 100 is inertia according to a change in acceleration while serving food, as well as vibration caused by uneven ground.

3 is a view for explaining the operating principle of the liquid overflow prevention system according to an embodiment of the present invention.

As described above with reference to FIGS. 1 and 2 , when a change in acceleration occurs, such as when the food transport device 100 reduces the speed while driving or, conversely, starts moving while stopped, inertia causes the food transport device to The liquid contained in the container 10 loaded in 100 may overflow to the outside while being drawn in one direction.

Hereinafter, a case in which the food transport mechanism 100 is a serving robot will be described as an example in the present specification, but the scope of the present invention is not necessarily limited thereto. As described above, the food transport device 100 is capable of autonomous driving like a serving robot, so it is not only a transport device capable of automatically serving food, but also a cart type that a person (employee) directly pushes and drags as needed. It may also be meant to include a passive transport device such as a transport device. In other words, if food, particularly liquid food, is loaded and transported for a predetermined distance, the liquid overflow prevention system according to the technical idea of the present invention, which will be described later, may be applied regardless of whether autonomous driving is possible or manual driving.

For example, as shown in FIG. 3 , when an acceleration is applied to the container 10 containing the liquid, the liquid inside the container 10 is drawn in one direction as shown in the figure on the right side of the drawing, and the container ( 10) It can overflow to the outside.

At this time, if the container 10 itself is tilted in the tilting direction, it is possible to prevent the liquid contained therein from overflowing to the outside of the container 10 . That is, the centrifugal force is generated while the container 10 rotates around the upper part of the container 10 to prevent the liquid contained therein from overflowing to the outside.

An object of the present invention is to provide a technical idea capable of preventing the contents from overflowing and splashing or flowing to the outside when the food transport device 100 serves liquid food with a relatively simple structure by using this principle.

4 to 5 are diagrams for explaining a liquid overflow prevention system according to an embodiment of the present invention.

Referring to FIG. 4 , the liquid overflow prevention system according to an embodiment of the present invention includes a accommodating part 210 formed to accommodate a container 10 containing liquid food, and the accommodating part 210 . It supports and may include a holder 220 whose upper end is formed to be mounted on a lower portion of the tray 110 provided in the food transport device 100 or a predetermined structure of the food transport device 100 .

Hereinafter, for convenience of description, the form including the accommodating part 210 and the mounting part 220 will be referred to as the first liquid overflow prevention system 200 according to the first embodiment.

At this time, the liquid overflow prevention system, that is, the first liquid overflow prevention system 200 may further include at least one locking part 111 formed so that the holder 220 can be hung by hanging. The locking part 111 may be formed in a ring shape or a protrusion shape so that the holder 220 can be hung by hanging, and the lower portion of the tray 110 and/or the food transport mechanism 100 as necessary. It may be formed on a predetermined structure of

According to an example, when the locking part 111 is formed in the lower portion of the tray 110 , as shown in the drawing, it may be formed within a predetermined distance from the lower edge of the tray 110 . Of course, the formation position of the locking part 111 is not necessarily limited to the position shown in the drawing, and if necessary, it is located in various positions such as a lower predetermined position of the tray 110 or the side part of the tray 110 .

The part 220 may be rotated in all directions within a predetermined range while shaking around the locking part 111 .

Accordingly, when inertia acts on the food transport device 100 while the food transport device 100 accelerates rapidly, decelerates, or vibrates due to irregularities or obstacles on the floor while driving, as shown in FIG. 5 . As the holder 220 is tilted (rotating) in a direction corresponding to the inertia applied to the food transport mechanism 100, the container 10 accommodated in the accommodation unit 210 is also tilted in the same way. It is possible to prevent overflow of the liquid accommodated in the container 10 .

Considering the driving speed of the food transport device 100, which generally serves food indoors, or the surrounding conditions such as the floor of a store, it is expected that a situation in which the holder 220 is inclined excessively enough to be detached will occur frequently. It is difficult, and there is a high possibility that there are not many cases in which excessive shaking occurs in the process of rotating (tilting) the mounting unit 220 and returning to its original position.

However, there may still be a risk that the liquid flow inside the container 10 accommodated in the receiving unit 210 may overflow due to excessive rotation (inclination) or vibration of the mounting unit 220 that may occur.

Therefore, depending on the embodiment, by combining a predetermined elastic body (eg, a spring, etc.) or a material having elasticity to the holding part 220, the rotation or vibration of the holding part 220 is alleviated, so that the inside of the container 10 is It is also possible to more effectively prevent the overflow of liquid.

The elastic body includes the upper end of the mounting portion 220 (eg, a coupling portion with the engaging portion 111 ), the body of the mounting portion 220 , and/or the lower end of the mounting portion 220 (eg, the receiving portion). The portion supporting the 210) may be applied to various locations as needed.

In addition, if necessary, an elastic body may be provided on the bottom of the accommodating part 210 as well as the holding part 220 to further prevent vibration or shaking of the container 10 accommodated in the accommodating part 210 .

6 to 8 are diagrams for explaining a liquid overflow prevention system according to another embodiment of the present invention.

6 to 7 , a liquid overflow prevention system (hereinafter, referred to as a second liquid overflow prevention system 300 according to the second embodiment) according to another embodiment of the present invention is a food transport mechanism A tray 110 provided in 100 to load food, a second holder 210 provided on the tray 110 and having an upper portion concave by a predetermined depth, and liquid food on the upper portion The container 10 is accommodated, and the lower part is convexly formed to correspond to the upper part of the second holder 210, and the second holder 210 is slidable from the upper part of the second holder 210 by a predetermined range. It may include a second accommodating part 220 coupled to the second cradle 210 .

In this case, the second accommodating part 220 may be inclined while sliding on the upper part of the second accommodating part 210 in a direction corresponding to the inertia acting on the food transport mechanism 100 , and the container 10 accommodated therein. may be inclined by a predetermined angle according to the inclination of the second accommodating part 220 .

As shown in FIG. 7 , the second accommodating part 220 may have a concave shape so that it can be easily accommodated in the container 10 . Of course, the shape of the second accommodating part 220 is not necessarily limited to the shape shown in the drawings, and may be implemented in various shapes if it can easily accommodate the container 10 containing liquid food as needed. can For example, when the container 10 is a cup-shaped container 10 , a cup holder may be provided in the second receiving part 220 to prevent falling due to sliding movement of the second receiving part 220 . may be

Meanwhile, according to an embodiment, a predetermined means for reducing friction may be provided on the second cradle 210 for smooth sliding of the second accommodating part 220 .

For example, as shown in FIG. 8 , at least one bearing 311 may be provided on the upper portion of the second holder 210 . In this case, when the lower portion of the second accommodating part 220 comes into contact with the bearing 311 and the second accommodating part 220 slides, the bearing 311 rotates and the second accommodating part 220 ) can be moved (sliding) smoothly.

9 to 10 are diagrams for explaining a liquid overflow prevention system according to another embodiment of the present invention.

Referring to FIG. 9 , in the liquid overflow prevention system according to another embodiment of the present invention, the method of tilting the container 10 containing the liquid flow may be the same or similar to the method described above in FIGS. 6 to 7 . have.

However, in the case of the third embodiment of the present invention shown in FIG. 9 , if the second holder 210 is mounted on the tray 110 and combined in the above-described second liquid overflow prevention system 300 , The second holder 210 may be embedded in the tray 110 . In this case, the surface of the tray 110 may have a flat shape even when the liquid overflow prevention system is applied.

According to another embodiment, the liquid overflow prevention system does not include a separate cradle 220 or a second cradle 210 as shown in FIG. 10 , and a receiving groove formed on the tray 110 . The second accommodating part 220 may be provided in the . In this case, the receiving groove formed in the tray 110 may be formed obliquely at a predetermined angle to become narrower toward the bottom as shown in the drawing, and the bearing 311 described above is located at a predetermined position on the side of the formed receiving groove. ) to induce sliding of the second receiving unit 220 . The receiving groove may be formed to penetrate the tray 110 as shown in the drawings, or may be formed not to penetrate the tray 110 according to an embodiment.

In any case, according to the technical idea of the present invention, the accommodating part 210 and/or the second accommodating part 220 accommodating the container 10 containing liquid food is affected by the inertia acting on the food transport mechanism 100 . By tilting the container 10 while tilting or sliding in a corresponding direction, it may be implemented to prevent overflow of liquid food due to acceleration, vibration, impact, or the like of the food transport mechanism 100 .

11 to 12 are diagrams for explaining a method of preventing escape of a liquid overflow prevention system according to an embodiment of the present invention.

First, referring to FIG. 11 , in order to prevent the second accommodating part 220 from being separated due to excessive tilting in the above-described second liquid overflow prevention system 300 , the lower part of the second accommodating part 220 is A sliding groove of a predetermined length may be formed at a position corresponding to the bearing 311 . In this case, at least an end of the sliding groove may be provided with a step difference or a separate protrusion or protrusion to prevent the bearing 311 from proceeding further.

Accordingly, since the second accommodating part 220 can slide only as much as the length of the sliding groove, it is possible to prevent separation of the second accommodating part 220 due to excessive sliding.

Meanwhile, referring to FIG. 12 , similarly, in the aforementioned second liquid overflow prevention system 300 , a separation prevention protrusion may be formed at a location spaced apart from the lower edge of the second accommodating part 220 by a predetermined distance.

In addition, the second cradle 210 may be provided with a separation sill at a position spaced apart from the center of the upper part by a predetermined distance.

Accordingly, when the second accommodating part 220 is slid by a predetermined distance, it may be characterized in that the separation preventing protrusion is not slid any more while being caught on the departure preventing protrusion.

In this case, unlike the example described above in FIG. 11 , separation due to excessive sliding of the second accommodating part 220 can be prevented even when the bearing 311 is provided as well as when the bearing 311 is not provided. have.

According to an embodiment, the second liquid overflow prevention system 300 may prevent excessive sliding of the second accommodating part 220 by controlling the acceleration of the food transport mechanism 100 .

According to an example, in the second liquid overflow prevention system 300 , a predetermined sensor (not shown) capable of detecting the sliding degree of the second accommodating part 220 and the sensor (not shown) A control unit (not shown) capable of adjusting the acceleration of the food transport mechanism 100 based on the detection result may be further included. The controller (not shown) may be connected to a drive system of the food transport device 100 to control the driving of the food transport device 100 (eg, acceleration, deceleration, driving, etc. of the food transport device 100 ). have. The sensor (not shown) may be disposed on the second cradle 210 and/or the second accommodating part 220 , and the second accommodating part 220 from the upper surface of the second cradle 210 . ) may be a sensor (not shown) capable of detecting the slid distance.

As a result of the detection of the sensor (not shown), when the second accommodating part 220 slides more than a predetermined standard, the control unit (not shown) adjusts the acceleration of the food transport mechanism so that the second accommodating part 220 is You can prevent it from sliding any further.

When the controller (not shown) controls the acceleration of the food transport device 100 , the controller (not shown) transports the food by changing the running speed and/or the running direction of the food transport device 100 . It may mean changing the acceleration of the instrument 100 .

In addition, the control unit (not shown) receives a detection signal sensed by the sensor (not shown) from the sensor (not shown), and based on the received detection signal of the sensor (not shown), the second receiving unit The degree of sliding of 220 may be detected. In an embodiment, that the control unit (not shown) detects the degree of sliding of the second accommodation unit 220 is based on a detection signal received by the control unit (not shown) from the sensor (not shown). It may mean determining the sliding distance of the second accommodating part 220 and determining the sliding degree of the second accommodating part 220 according to the slid distance. For example, the control unit (not shown) may determine that the sliding degree of the second receiving unit 220 is appropriate when the sliding distance of the second receiving unit 220 is within a predetermined reference distance. When the sliding distance of the second accommodating part 220 deviates from the previously stirred reference distance, it is determined that the second accommodating part 220 is slid excessively and the acceleration of the food transport mechanism 100 may be adjusted.

For example, as shown in FIG. 6 , when the food transport device 100 decelerates while driving, the second accommodating part 220 may slide toward the front of the food transport device 100 . At this time, when the food transport mechanism 100 is rapidly decelerated (that is, when the change in acceleration is large), the sliding of the second accommodating part 220 is excessively performed and the second accommodating part 220 is separated or the The container 10 accommodated in the second accommodating part 220 may fall over. Accordingly, the controller (not shown) controls the driving of the food transport device 100 so that the degree of deceleration of the food transport device 100 is not sudden (ie, the acceleration is not large) (eg, the food transport device 100). ), the sliding degree of the second accommodating part 220 may be maintained within a certain level or the second accommodating part 220 may be returned to its original position. For example, as shown in FIG. 6 , if the food transport device 100 while driving rapidly decelerates and the second accommodating part 220 excessively slides in the front direction, the controller (not shown) controls the food transport device. (100) is accelerated in the original driving direction to cancel the acceleration applied to the second receiving unit 220, so that the second receiving unit 220 is moved in the opposite direction (eg, the rear direction of the food transport mechanism 100) It is possible to prevent excessive sliding by receiving inertia.

Similarly, even when the food transport device 100 starts from a stop state, when the acceleration is large (eg, rapid acceleration), the second accommodating part 220 is excessively moved toward the rear side of the food transport device 100 . can be slid. In this case, the control unit (not shown) may reduce the degree of acceleration or deceleration of the food transport device 100 to maintain the sliding degree of the second accommodation unit 220 at an appropriate level.

Meanwhile, according to the technical idea of the present invention, the food transport mechanism 100 to which the liquid overflow prevention system as described above is applied may be provided.

The food transport device 100 accommodates a driving unit for driving, a tray 110 on which food can be loaded, and a container 10 containing food, and an upper end of the food transport device 100 is a lower portion of the tray 110 or the food transport device ( 100) may include a liquid overflow prevention system (eg, the first liquid overflow prevention system 200) mounted on a predetermined structure (eg, the frame, body, etc. of the food transport device 100).

The liquid overflow prevention system (eg, the first liquid overflow prevention system 200 ) according to an embodiment is inclined within a predetermined range in a direction corresponding to the inertia acting on the food transport mechanism 100 , and the container It is possible to prevent overflow by offsetting the inertia applied to the food in (10).

According to another embodiment, the food transport mechanism 100 includes the driving unit, a tray 110 on which food can be loaded, and a liquid overflow prevention device provided on the tray 110 to accommodate a container containing food. a system (eg, second liquid flow overflow prevention system 300 ).

In this case, the liquid overflow prevention system (eg, the second liquid overflow prevention system 300 ) slides by a predetermined range and a predetermined angle in a direction corresponding to the inertia acting on the food transport device 100 , the upper part of which is It is possible to prevent overflow by offsetting the inertia applied to the food in the container 10 as it is tilted.
