The manner in which the transfer device is coupled to the transfer rail is further described below in conjunction with fig. 9. Fig. 9 shows a schematic view of a transfer device in mating connection with a transfer rail of a different cross-section. In one example, as shown in fig. 9(a), the rail system is two parallel conveying rails, the rollers of the conveying device are arranged on the inner sides of the two rails, the cross section of the rollers is adapted to the cross section of the rails, and as an example, when the cross section of the rails is a convex circle, the cross section of the rollers is a circular arc-shaped groove adapted to the circle, the rollers can be in more contact with the rails, and thus the rollers can be better kept on the conveying rails. A spring (not shown) applies a spring force F directed outward of the track to the roller via the frame, thereby maintaining the roller in a mating connection with the conveyor track. In another example, as shown in fig. 9(B), the rail system is two parallel conveying rails, the rollers of the conveying device are arranged on the outer sides of the two rails, the cross section of the rollers is adapted to the cross section of the rails, and as an example, when the cross section of the rails is (convex) circular, the cross section of the rollers is grooves adapted to the circular shape. A resilient member (not shown) applies a resilient force F directed towards the inside of the track to the roller via the frame, thereby keeping the roller in a mating connection with the conveyor track. In another example, as shown in fig. 9(C), the rail system is a single conveying rail, rollers on both sides of the conveying device are disposed on both outer sides of the single rail, and the cross section of the rollers is adapted to the cross section of the rail, and as an example, when the cross section of the rail is h-shaped like, the convex portions of the rollers are adapted to the concave portions of the rail. A resilient member (not shown) applies a resilient force F directed towards the track via the frame to the roller, thereby keeping the roller in a mating connection with the conveyor track. Alternatively, in order to keep the conveyor running smoothly on a single conveyor track without tipping over, safety devices may be provided, for example safety wheels under the rollers against the conveyor track or the carriage of the conveyor track. The safety device may employ safety features common in the art for monorail systems, and is not limited in this application. In yet another example, as shown in fig. 9(D), the track system is two parallel conveying tracks, rollers on both sides of the conveyor are arranged above the two tracks, the cross section of the rollers is adapted to the cross section of the tracks, and when the track cross section is (convex) circular, the cross section of the rollers is, as an example, grooves adapted to the above circular shape. The
The positioning device of the conveyor and its operation will be described with reference to fig. 10. Fig. 10 shows a schematic view of the positioning operation of the transport device on the rail system. The conveying device comprises a positioning device, the positioning device acquires corresponding position information on the track system and sends the position information to a main controller of the conveying device, and the main controller controls the running speed of the conveying device according to the position information, such as acceleration, deceleration, continuous running or stopping.
In one embodiment, the positioning device of the conveying device may be a radio frequency positioning device, which may be a radio frequency card reader. One or more radio frequency tags (e.g., N tags) are disposed on the transfer track of the track system. The radio frequency tag can be arranged on the conveying track or on the track support, so that when the radio frequency card reader approaches the radio frequency tag, the information on the radio frequency tag can be scanned through the radio frequency card reader. The radio frequency tags may correspond one-to-one with specific location points on the track system, thereby identifying location information for these specific location points. As shown in fig. 10, radio frequency tags T1, T2, T3 … … Tn may be disposed on a transport track beside a table or a seat to identify position information of the table or the seat. For simplicity of description, fig. 10 shows only the tables and seats corresponding to the rf tag T2, so that the tag T2 can uniquely identify the tables and seats there. Alternatively, the rf tag may be positioned slightly forward of the track, thereby providing a suitable stopping distance for the conveyor to rest at the table or seat. During the operation of the conveyors V1-V3, the radio frequency card reader can scan the radio frequency tags T1-T3 to obtain the ID information of the radio frequency tags.
In another embodiment, the positioning device of the transport device may be an optical positioning device, which may be an optical sensor. One or more optical labels (e.g., N labels) are disposed on the transport track of the track system. The optical label can be arranged on the inner side of the conveying track or on the track support, and the pattern or the figure on the optical label faces the optical sensor, so that the pattern or the figure on the optical label can be scanned by the optical sensor. The optical labels may have a one-to-one correspondence with specific location points on the track system, thereby identifying location information for these specific location points. The location distribution of the optical tags T1, T2, T3 … … Tn on the tracks can refer to the above distribution of the rf tags, which is not described herein again.
The following description will proceed to the positioning operation of the transmitting device by taking the rf positioning device as an example. As shown in fig. 10, when a customer sits at a dining table or a seat identified by the rf tag, the information of the food and/or beverage ordered by the customer and the rf tag T2 is returned to the main control device of the restaurant along with the order, and the food and/or beverage and the information of the rf tag T2 form a corresponding relationship. The order can be completed through handwritten records of staff, and can also be completed through ordering equipment placed on each dining table or seat. The ordering device can be any known type of intelligent terminal, such as a mobile phone, a tablet computer and the like; the main control device of the restaurant may be a server or an intelligent terminal of a known type, which is not limited in this application. With the ordering device, the order can be generated immediately after the order of food and/or beverage is finished, so that the ordering efficiency and accuracy of the customer can be improved. It should be noted that the number of the dining table or the seat, the ID of the ordering device placed on the dining table or the seat, and the ID of the tag at the track position beside the dining table or the seat are in a one-to-one correspondence relationship, and the correspondence relationship may be stored in the main control device of the dining table or in each transport device, so that the correspondence relationship may be called at any time when needed. To reduce the complexity of the description, the present application will be described with a "tag", it being understood that the tag is positionally corresponding to a table or a seat, and an ordering device placed on the table or the seat.
For the dishes ordered by the customer of the rf tag 2, after the kitchen of the restaurant finishes cooking or prepares food and/or beverage, a dish tag may be attached to the outer package of the food and/or beverage, and the information of the dish tag corresponds to the information of the rf tag T2, which may be obtained from the aforementioned order. Before or when food and/or beverage is put into the conveying device, the conveying device scans the dish label through the radio frequency card reader, so that the information of the target position label is obtained and stored in the conveying device. In fig. 10, at least three conveyors V1, V2 and V3 run on the track system. Food and/or beverages may be placed in any of the three conveyors described above. Taking food and/or beverage to be placed into the conveying device V2 as an example, after the conveying device V2 acquires and stores information of a target position tag T2, the conveying device V starts to run along a track system, sequentially scans the radio frequency tags T1 and T2, compares the acquired radio frequency tag information with the stored target position tag information (i.e., tag T2), and when the information is inconsistent, the main controller of the conveying device controls the conveying device to continue to run along the track; when the above information is in agreement, the master controller sends a stop signal to the speed controller, so as to stop the conveyor at the radio frequency tag T2, waiting for the customer to take the food and/or beverage loaded on the conveyor. Alternatively, the comparison of the information may be performed at the main control device of the restaurant, in which case the transmitting means transmits the radio frequency tag information and the stored destination location tag information to the main control device of the restaurant, which receives and compares the information and then transmits the result back to the transmitting means. Alternatively, the master or master may control the conveyor to speed up or slow down as it passes a tag at a predetermined location.
When the positioning device of the transmission device is an optical sensor, the working mode of the transmission device is similar to that of the radio frequency positioning device, and the means for scanning the label to obtain the label information is different, which is not described herein again.
In some embodiments, when the positioning device of the conveying device is a radio frequency positioning device, the dish tag may be an optical tag, in which case an optical sensor may be further disposed on the conveying device to obtain information identifying the dish tag. In other embodiments, when the positioning device of the conveying device is an optical positioning device, the dish tag may be a radio frequency tag, in which case, a radio frequency card reader may be further arranged on the conveying device to obtain information of the dish tag identification.
In other embodiments, the conveyor may be provided with a keypad entry device, and the operator may enter information about the target tag into the conveyor so that the conveyor may convey the carried food and/or beverage to the location of the target tag.
Alternatively, the positioning of the conveyor can also be achieved with a simplified rail system. In one example, each conveying track corresponds to a table or a seat, only one label is arranged at the corresponding position on the conveying track, food and/or beverage can be directly placed into the conveying device, and the conveying device conveys the carried food and/or beverage to the position of the target label to stop, so that the process of scanning the dish label can be omitted. In another example, each conveying track corresponds to a table or a seat, and a brake device is arranged at a corresponding position on the conveying track and used for preventing the conveying device from moving to the position and then continuing to advance. The braking device may be a fence or similar barrier that blocks the conveyor from continuing to advance when the conveyor is operated to the corresponding position. Thereby, the structure of the transport device can be further simplified, and the transport device can be positioned at a predetermined position of the rail system.
The conveying device can also form two or more conveying device combinations through the traction structure between the conveying devices, so that more articles can be conveyed to the target position at one time. Fig. 11 shows a schematic structural view of a conveyor assembly, as shown in fig. 11, with a mounting
The transmission device combination can be formed by mutually connecting a plurality of power transmission devices, or can be formed by connecting a power transmission device with a non-power transmission device.
In one example, as shown in fig. 11, the conveyor assembly may consist of a powered conveyor traction coupled to a
In another example, the transmission combination may be formed by tow-coupling of two or more power transmissions, which may have the same structure. Alternatively, the power transmission device may have a different structure so that different articles can be transported at once.
In another example, the conveyor combination may be formed of a hybrid grouping of powered and unpowered conveyors so that different items may be transported at once as desired.
The circuit portion of the transmission device will be described with reference to fig. 12. Fig. 12 shows a block diagram of a circuit structure of a transmitting apparatus, and as shown in fig. 12, a
