Description

Conveying control system and method of automatic meal preparing equipment
Technical Field
The present disclosure relates to automated meal preparation technology in the field of dining. More particularly, the present disclosure relates to automatic meal preparation equipment and transport control systems and methods for automatic meal preparation equipment.
Background
In the catering industry, and in particular the fast food industry, a common problem is that food needs to be distributed for a large number of different customer orders, and it is desirable to achieve as much as possible a first come first, i.e. a customer placing a first order will get his desired food first, regardless of the number and kind of food in his order. Currently, automatic meal preparing apparatuses have been started to improve meal preparing efficiency and to avoid mistakes caused by manual operations as much as possible.
However, in practical applications of catering, it is often not possible to use a large number of parallel processing systems to solve the problem of random combination of multiple types of foods due to the limitation of restaurant area. Thus, for automatic catering applications in restaurants, only one conveyor line is typically deployed and food combinations need to be made at will in standard containers (e.g. cutlery baskets) according to the customer's order, which requires that the containers be stopped accurately at the positions corresponding to the respective food products and that the containers be able to travel to the next food station according to the order (or task issued by the system). Of course, the combination of foods in each order is random and automatically generated based on the customer's order. Thus, the stations at which containers corresponding to each order need to be stopped in order to receive food products there are also randomly combined.
To accommodate different food product combinations and to increase the efficiency of meal preparation and delivery, it is necessary to control the position and start-stop of different containers on the same conveyor line in order to automatically and accurately match different orders.

-determining the current position of each container;
-determining the distance between the current position of each container and its target working position; and
-controlling the movement of all containers such that the container closest to the target working position reaches and stops at the target working position of the container.
The present disclosure also provides a delivery control system for an automatic meal delivery apparatus having a plurality of food dispensing stations for dispensing food according to an order, and including a delivery line for delivering food, at least two containers being positionable on the delivery line to respectively reach and stop with movement of the delivery line at a target working position corresponding to one or more of the food dispensing stations to receive food matching the respective order at the target working position, the delivery control system comprising:
-position detection means for determining the current position of each container; and
-a control unit configured to receive an input of the position detection device and to control the movement of the conveyor line such that each time it is ensured that the container closest to its target working position arrives and stops at its target working position.
The multi-station parallel effect is realized on a single-row conveying line, and the efficiency of catering (namely food distribution) is improved.
The present disclosure also relates to an automatic catering apparatus having a conveyor control system as described above.
Drawings
Features and advantages of embodiments of the present disclosure will become apparent with reference to the following detailed description and accompanying drawings in which:
fig. 1 is a schematic view of a conveyor line of an automatic meal preparation apparatus of the present disclosure to which the conveyor control system and method of the present disclosure may be applied.
Detailed Description
The technical scheme of the present disclosure is further specifically described below by way of examples and with reference to the accompanying drawings. The following description of the embodiments of the present disclosure with reference to the drawings is intended to illustrate the general inventive concept and should not be taken as limiting the disclosure.
Furthermore, in the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments. It may be evident, however, that one or more embodiments may be practiced without these specific details. Furthermore, well-known structures and devices are not shown in the drawings in order to simplify the drawings.
Referring to fig. 1, the automatic catering apparatus of the present disclosure comprises a conveyor line 1 and a plurality of food holding devices (not shown) for dispensing food towards the conveyor line 1, such as hamburger bins, french fries bins, chicken nuggets or chicken popcorn bins, etc., either zoned or with a slide way. The food storage device may be mounted beside the conveyor line 1, e.g. sideways or above it, at a predetermined food dispensing station in order to dispense the desired food according to the customer's order. In particular, the food in the food storage device may be dispensed onto the conveyor line 1, in particular into a container placed on the conveyor line 1, for example by gravity falling or being grasped by a food dispensing mechanism such as a robotic arm.
For this purpose, the containers may be stopped on the conveyor line 1 in a position corresponding to the food dispensing station in which the food storage device is located, also called the food placement position or working position 11, 12, 13, 14, in order to receive the food product from the respective food storage device.
As shown in fig. 1, two or more containers 20, 21, 22, 23, 24, 25, in particular meal baskets of standard dimensions, can be placed on the conveyor line 1. Each container may correspond to an order and may be moved with the conveyor line 1 from the container placement position 10 at one end (left end in fig. 1, referred to herein as the "start end") of the conveyor line 1 toward the container removal position 15 at the other end (right end in fig. 1) of the conveyor line 1 to stop at one or more of the work positions 11-14 in the process as required by the associated order to receive the one or more food products required in the order.
In the example shown in the figures, the conveyor line 1 may be constituted by a conveyor belt, in particular an O-belt. The conveyor line 1 may be driven by a driving device (not shown) for intermittent movement. Thereby, all containers can be moved or stopped by the conveyor line 1. In particular, the movement of these containers on the conveyor line 1 is unidirectional, i.e. moves from the container placement position 10 towards the container removal position 15.
As can be seen from fig. 1, the conveyor line 1 is preferably a single conveyor line and all containers 20-25 are placed on the conveyor line 1 in series or in a row. Moreover, the number of containers on the conveyor line 1 may be positively correlated with the number of working positions at the conveyor line 1, i.e. the more working positions at the conveyor line 1 the greater the number of containers that can be placed thereon and vice versa. In particular, the number of containers is less than or equal to the number of stoppable positions at the conveyor line (including the working position, the container placement position, and the container removal position).
When a container is placed at the container placement location 10 at the conveyor line 1, which is the starting location of the container on the conveyor line 1, the container may be assigned an identification code, for example by the order system host computer, and associated with an order such that the container collects the food product required in the order during movement. This process of associating containers with orders may be accomplished, for example, by a detection device and a software and hardware module for detecting containers present on container placement site 10.
The delivery control system of the present disclosure may include a position detection device for determining the current position of each container. In particular, the position detection means may be detection means for determining the position of each container by monitoring the moving distance thereof. For example, the position detection means may comprise an opto-electronic encoder arranged below the conveyor line 1, in particular below the container placement position 10. The linear distance traveled by the conveyor line 1 from the time each container is placed in the container placement position 10 can be measured by means of an optoelectronic encoder, whereby the real-time or current position of each container is determined.
The conveyor control system of the present disclosure may further comprise a control unit for controlling the start and stop of the conveyor line 1 to stop one or several containers in a desired working position (also called target working position). The control unit may be part of the order system host computer or a separate unit in communication with the host computer. The control unit may comprise software and hardware modules and may activate or deactivate the drive means for driving the conveyor line 1 to move or deactivate containers, in particular all containers, on the conveyor line 1 simultaneously.
The control unit may be configured to receive information of an order associated with each container in order to determine at which working position or positions of the conveyor line 1 the respective container should be stopped, and may also be configured to receive information from the position detection device characterizing the current position of each container.
In particular, the control unit may comprise means for calculating the distance between the current position of each container and the target working position at which the container is to be stopped. The target working position is in particular the closest target working position to the current position of the container.
The control unit may further comprise means for comparing the distances between the current positions of all containers and their target working positions in order to determine a minimum distance.
Furthermore, the control unit may also comprise an actuation module for activating the driving means of the conveyor line 1 and moving the conveyor line 1 said minimum distance.
The following describes a conveyance control method of the automatic meal preparing apparatus of the present disclosure with reference to fig. 1.
1) When the conveyor line 1 is in a stopped state, a container is placed in the container placement position 10 of the conveyor line 1 by manual or automatic means (see, for example, container 20 in fig. 1, assuming that only one container is present on the conveyor line 1 at this time);
2) When the presence of the container is detected, assigning, by the host system, an identification code to the container and matching the container with an order;
3) After placement is completed, the conveyor line 1 is activated by the control unit to move the container to a food placement position (i.e. one of the work positions 11-14 in fig. 1, assumed to be work position 11) corresponding to the food product specified in its associated order. In the process, the distance of forward movement of the conveyor line 1 is measured by a position detection device (e.g. a photoelectric encoder) arranged below the conveyor line 1 and the real-time position of the container is tracked thereby;
4) After the conveyor line 1 moves the container (herein referred to as "first container") to the corresponding target working position (herein assumed to be "working position 11" as described above), the conveyor line 1 is stopped by the control unit and the dispensing of the food product to the container (e.g. the placement of one or more hamburgers into the container) is started by the food dispensing mechanism. At the same time, a new container (referred to herein as a "second container") is placed again on the container placement site 10 of the conveyor line 1, and the identification code and order information are assigned to the new container;
5) Comparing by the control unit the distance that the first container (in case the conveyor line 1 is moved from left to right in fig. 1, where the first container is located to the right of the second container) needs to be moved each to its target working position, e.g. the second container needs to be moved from the current container placement position 10 to the working position 11 (i.e. 1 grid needs to be moved) in order to receive hamburgers, whereas the first container needs to be moved from the current working position 11 to the working position 13 (i.e. 2 grids needs to be moved) in order to receive french fries, the control unit activates the conveyor line 1 to move it only one distance of the working position, thereby ensuring that the second container is prioritized to its target working position, and after the second container reaches the target working position, the control unit stops the conveyor line 1 from moving;
6) At this time, the first container does not reach its target working position, and is in a waiting state, while the second container is stopped at its working position, and food is dispensed into the second container by the food dispensing mechanism at the position. Meanwhile, a third container may be placed at the container placing position 10 of the conveyor line 1;
7) After the third container is placed and bound to the order, repeating the contrast step in step 5) to compare the distance between the respective current position of the first, second and third containers and the next target working position thereof, and controlling the start and stop of the conveyor line 1 to travel so that the container closest to the target working position reaches and stops at the target working position thereof, and then dispensing the food into the container; and so on.
When the rightmost container reaches the container removal position 15, it can be removed from the conveyor line 1 by an automated device and supplied to the customer.
Various modifications and alterations to the above disclosed embodiments may be made by those skilled in the art without departing from the scope or spirit of this disclosure. Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure. It is intended that the specification and examples disclosed herein be considered as exemplary only, with a true scope of the disclosure being indicated by the following claims and their equivalents.
