The meal delivery system can be divided into two types of land and non-land according to different operation places. By land it is meant that the food delivery system is operated on land, and such food delivery system includes a food delivery cart 20 and static discharge means. The serving trolley 20 provides navigation, mobility, and is used to receive and transport meals. The static electricity removing device provides a moving place for the dining car 20 and removes static electricity generated by the movement of the dining car 20. The static electricity removing device is installed on the floor and introduces static electricity to the ground.

The non-land-based food delivery system is installed in a high-altitude area at a certain height above the ground, and the static electricity removing device is hung on an object such as a ceiling 50 to remove static electricity through the ceiling 50.

It will be appreciated that the meal placed on the cart 20 is specifically composed of a meal tray and food placed in the meal tray, i.e., the meal tray mentioned later, which is filled with food.

Referring to fig. 1 and fig. 2, a static electricity removing apparatus according to an embodiment of the present application includes: a track 10, a power-guiding mechanism 30 and a conductive mechanism 40. The track 10 is used for connecting a production place of food and a customer place, and the food delivery trolley 20 runs on the track 10, namely, the track 10 is used for carrying the food delivery trolley 20 to move food delivery. The rail 10 is installed in an overhead area at a certain distance from the ground, so that the rail does not occupy the ground space, can improve the passenger capacity of the dining room to a certain extent, and improves the economy.

And in this embodiment the track 10 is made of a non-conductive material. For example, the rail 10 is made of glass, acrylic, transparent high-strength plastic, etc. Preferably, the track 10 is made of glass. The glass has the advantages that the glass material is lower in manufacturing cost and beneficial to improving the economy; in addition, glass is transparent material, when serving trolley 20 frequently reciprocates to walk on transparent glass track 10, can give the certain sight of the customer who is in the below, and the intelligent level in reinforcing food and beverage place does benefit to and promotes customer's dining experience. Wherein, track 10 adopts the rectangular glass board to make, and whole track 10 can adopt a monoblock glass to make, also can adopt the concatenation of polylith glass to constitute, specifically can select according to actual need.

The food cart includes an AGV car 21, a pallet 22 mounted on the AGV car 21, and some accessories. Has excellent self-moving capability. The tray 22 is provided with a cover which can be opened and closed, when the meal is conveyed, the cover covers the meal, so that the sanitation of the meal can be ensured, and a certain heat preservation effect can be realized.

The electricity leading mechanism 30 is arranged on the track 10 and is used for leading static electricity accumulated on the dining car 20 away; the conducting mechanism 40 is electrically connected to the electricity guiding mechanism 30 and is used for guiding the static electricity drawn from the dining car 20 by the electricity guiding mechanism 30 to an external object. It is understood that the external object may be a ceiling, a floor, a wall, etc.

Referring to fig. 1, the meal delivery system is illustrated as a non-land type in the present embodiment. In this case, the conductive mechanism 40 includes a bracket 41 connected to the track 10 and in contact with the electricity guiding mechanism 30, and a hanger 42 having one end connected to the bracket 41 and the other end of the hanger 42 for being hung on the ceiling 50. That is, the track 10 is supported and fixed by the bracket 41 and then suspended from the ceiling 50 by the suspension 42, so as to realize the purpose of the trolley 20 running in the air. Specifically, the bracket 41 may be a single-sided arrangement, in which case the hangers 42 are multiple and connected between the bracket 41 and the ceiling 50 in a single row at intervals. Or two brackets 41 may be disposed on both left and right sides of the track 10, and the suspension members 42 are still plural, but are disposed in two rows, each row being connected between one bracket 41 and the ceiling 50. Preferably, the rail 10 of the present embodiment adopts a suspension mounting structure with the brackets 41 at both sides, so that the mounting strength is higher, the rail 10 can be stably mounted, and the stable and safe high-altitude operation of the dining car 20 can be ensured to the maximum extent.

Optionally, the bracket 41 is an angle iron. The track 10 can be directly erected on a right-angle concave table of the angle steel, and the installation mode is simple. Certainly, in order to further ensure that the guide rail is stably installed, a fastener can be arranged on the angle steel, the glass guide rail is buckled and pressed through the fastener, or the glass guide rail is adhered and fixed in a gluing mode. Further, the hanger 42 may be a steel wire sling. The steel wire lifting rope has high structural strength, is easy to obtain and is convenient to install; the distance between the two rows of steel wire lifting ropes can be controlled, so that the distance between the brackets 41 on the two sides can be controlled, and the brackets 41 can stably clamp and fix the track 10.

In summary, the implementation of the technical solution of the present embodiment has the following beneficial effects: the application of the static electricity removing device is equipped in the food delivery system, and the static electricity generated by contact friction between the food delivery trolley 20 and air and the like in the moving process can be timely and effectively guided to an external object, so that the influence of the static electricity on the running precision and the dining experience is eliminated. Specifically, the serving trolley 20 reciprocates on the track 10 during operation, wherein the track 10 is made of non-conductive material, so as to achieve the purposes of reducing cost and improving reliability. Static electricity generated by relative movement friction of the serving trolley 20 and objects such as air, the track 10 and the like can be accumulated on the shell of the serving trolley 20, but because the electric leading mechanism 30 is installed on the track 10, when the serving trolley 20 moves through the electric leading mechanism 30, the serving trolley 20 is in contact with the electric leading mechanism 30, and the electric leading mechanism 30 can lead the static electricity on the serving trolley 20 down, namely the static electricity on the serving trolley 20 is removed completely; then, the leading mechanism 30 leads the led-down static electricity to the conductive mechanism 40, and finally the static electricity is led to an external object by the conductive mechanism 40, so that the static electricity elimination is realized. In conclusion, the food serving trolley 20 can timely and effectively remove and eliminate generated static electricity through the cooperation of the static electricity removing device and the scheme, and the influence of static electricity accumulation on the running precision of the food serving trolley 20 and the dining experience of customers is avoided.

Referring to fig. 2 and fig. 3, in some embodiments, the electricity guiding mechanism 30 includes an electricity guiding body 31, the electricity guiding body 31 is disposed on a surface of the track 10 and is used for contacting and conducting with the dining car 20, and the electricity guiding body 31 is in contact and conducting with the conducting mechanism 40. Specifically, the electricity-leading body 31 is a conductive object manufactured and molded by metal, composite material and the like, and can be in the shape of plate, block, strip, belt and the like, and is directly installed on the surface of the guide rail, so that the food serving trolley 20 can be directly contacted with the electricity-leading body 31 to form conduction when moving, and static electricity accumulated on the food serving trolley 20 can rapidly move to the electricity-leading body 31, thereby achieving the purpose of removing the static electricity on the food serving trolley 20. The structure and the installation mode of the attractor 31 are simple, the implementability is strong, and the static electricity removing effect is good.

In order to avoid that the electric lead 31 is loosened when the dining car 20 moves past, in some embodiments, the electric lead mechanism 30 further includes an adhesive member, and the electric lead 31 is adhered to the surface of the track 10 by the adhesive member. Thus, the electricity-leading body 31 can be more firmly fixed on the surface of the rail 10 by the adhesive force of the adhesive member, and is more stable and reliable when meeting with the dining car 20, thereby ensuring that the electricity-leading body 31 can remove static electricity. Alternatively, the adhesive member may be, but is not limited to, a double-sided tape or the like.

It is understood that the lead 31 and the adhesive member in the above embodiments can be combined into a conductive device with self-adhesive capability, such as, but not limited to, a self-adhesive conductive aluminum foil tape, a self-adhesive conductive copper foil tape, etc. At this time, the end portions of the lead 31 are adhered to and covered on the surfaces of the brackets 41 on both sides, so as to ensure the conduction of the current transmission path between the lead 31 and the conductive mechanism 40.

Of course, in other embodiments, the adhesive member may be replaced by a suction cup, and the electric conductor 31 may be fixed by vacuum suction; or the sticking piece is replaced by a magnet, the magnet is also arranged on the electric attracting body 31, and the electric attracting body 31 is arranged and fixed by the magnetic attraction force of the two magnets; or the sticking piece can be replaced by a magic tape, a magic tape female tape is arranged on the electricity leading body 31, and the electricity leading body 31 can be reliably arranged by means of the adhesion of the magic tape male tape and the magic tape female tape.

It should be noted that, for the case that the transportation path has a long stroke and needs to be reciprocated, the lead body 31 is preferably adhered to the middle position of the rail 10, so as to ensure that the lead body 31 can be contacted to achieve the purpose of eliminating static electricity when the dining car 20 is reciprocated.

As an alternative to the above embodiments, in other embodiments, the electric lead mechanism 30 includes an electric lead 31, a receiving and fitting recess is formed on the surface of the rail 10, the electric lead 31 is fitted in the receiving and fitting recess, and the electric lead 31 is in contact with the conductive mechanism 40 for conduction. Thus, the lead body 31 can be fixed in the embedding concave part in an embedding mode, and the reliable contact with the serving trolley 20 is guaranteed, and meanwhile, the installation stability of the lead body can be guaranteed. The lead body 31 may be made of a strip, a plate, a belt or the like made of a conductive material such as metal, and may be fastened by the inner wall of the fitting recess and the gravity of the lead body. Preferably, the surface of the power lead 31 is flush with the notch of the receiving concave portion, or may be slightly higher than the notch of the receiving concave portion, so as to ensure that the power lead 31 can be reliably contacted with the dining car 20 when moving at high speed. Of course, the surface of the lead 31 may be slightly lower than the notch surface of the receiving recess under the condition that the dining car 20 is driven at a slower speed to ensure contact with the lead 31.

Further, as an alternative to the above embodiments, in still other embodiments, the electric lead mechanism 30 includes an electric lead body 31, the rail 10 includes two rail bodies spliced to each other, the electric lead body 31 is installed at a splice between the two rail bodies, and the electric lead body 31 is in contact conduction with the conductive mechanism 40. Thus, the lead body 31 can be installed and fixed by clamping and fixing the lead body 31 in the abutted seam of the two adjacent sections of the rail bodies, and the lead body 31 is ensured to be reliably contacted with the passing serving trolley 20. At this time, the connection manner of the lead body 31 and the two adjacent rail bodies may be, but not limited to, bonding, snap connection, plugging, hoop connection, and the like, and may be specifically selected according to actual needs.

In particular, in order to improve the electrostatic elimination effect of the dining car 20 when the track 10 is long, which results in long moving time of the dining car 20 on the track 10 for a single meal delivery operation, in some embodiments, the number of the electricity-leading mechanisms 30 is at least two, i.e. the number of the electricity-leading bodies 31 can be two or more, and at least two electricity-leading mechanisms 30 are disposed adjacent to or spaced apart from each other on the track 10 along the moving path of the dining car 20. When the meal delivery trolley 20 moves in one direction, the meal delivery trolley can be in contact with different electric conductors 31 for at least two times (for multiple times) in a front-back mode, static electricity can be eliminated for at least two times (for multiple times), the effect that static electricity is generated in real time and is eliminated in real time is achieved, the running precision of the meal delivery trolley 20 can be greatly improved, the noise production amount is reduced, and the dining experience of customers is improved.

On the basis of the above embodiment, the track 10 may be formed by a plurality of track bodies, and the number of the track bodies is one more than that of the lead bodies 31, so that the lead bodies 31 may be clamped in the abutted seams of any two adjacent track bodies in a one-to-one correspondence.

Furthermore, in still other embodiments, the electricity guiding mechanism 30 includes a fixing base, an elastic expansion member disposed on the fixing base, and a conductive wheel connected to the elastic expansion member, a mounting groove is concavely disposed on the surface of the track 10, the fixing base, the elastic expansion member, and the conductive wheel are disposed in the mounting groove, a rim of the conductive wheel extends out of a notch of the mounting groove and is used for contacting and conducting with the dining car 20, and the fixing base is contacted and conducting with the conductive mechanism 40. Therefore, the food delivery trolley 20 can contact with the conductive wheels during the travelling process, and the generated static electricity is conducted to the conductive mechanism 40 through the conductive wheels and then is finally transmitted to the ceiling 50 or the bottom plate, so that the static electricity is eliminated. And meanwhile, the conductive wheels are pressed by the food delivery trolley 20 to synchronously compress the elastic expansion pieces to contract, and the conductive wheels are ensured to be in contact with the food delivery trolley 20 and can be contracted and hidden in the mounting groove, so that the phenomenon that the food delivery trolley 20 is blocked due to movement of the food delivery trolley 20 and is vibrated, the problem that the loaded food is splashed is caused, and the operation reliability of a food delivery system is influenced.

Or, alternatively, in some other embodiments, the electricity-leading mechanism 30 includes an electricity-transmitting dragging member, one end of which is used for connecting with the dining car 20, and the other end of which is movably connected with the electricity-conducting mechanism 40. Compared with the solutions of the above embodiments, the present embodiment can only eliminate static electricity when the dining car 20 passes through the electricity-guiding mechanism 30 and makes contact with the electricity-guiding mechanism, and the difference of the present embodiment is that a normally-contacted conducting state between the dining car 20 and the conducting mechanism 40 can be formed by the electricity-transmitting dragging member, that is, static electricity generated during the movement of the dining car 20 can be conducted to the conducting mechanism 40 in real time through the electricity-transmitting dragging member, so as to achieve the purpose of eliminating static electricity in real time. The capability of ensuring the driving precision of the dining car 20 is stronger, and the electric shock noise of crack can be furthest avoided. Specifically, the electric actuator may be a drag chain, a metal elastic rope, a metal elastic belt, or the like. To ensure reliable relative movement between the electric actuator and the conductive mechanism 40, the electric actuator may be connected to the bracket 41 of the conductive mechanism 40 via a conductive clip, a roller, or the like.

According to actual needs, the moving paths of the electricity leading mechanisms 30 and the dining car 20 are arranged in parallel or in a crossed manner or in a mutually perpendicular manner. Therefore, the difficulty in installing and arranging the electricity guiding mechanism 30 can be reduced, and at the moment, the food delivery trolley 20 only needs to be ensured to be reliably contacted with the electricity guiding mechanism 30 and the static electricity is guided to be removed.

Further, each of the electricity-leading mechanisms 30 cooperates to form a pattern distribution. For example, the food delivery system can be various patterns, animal patterns, specific LOGO patterns and the like, so that the decoration effect can be formed on the guide rail, and the attractiveness of the food delivery system is improved.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
