Since the first mount 3310 is located at the upper layer when applied to the drink making apparatus, the first mount 3310 may also be referred to as an upper mount 3310, the second mount 3320 is located at the middle layer, the second mount 3320 may also be referred to as a middle mount 3320, the third mount 3330 is located at the lower layer, the third mount 3330 may also be referred to as a lower mount 3330, and the first mount 3310, the second mount 3320 and the third mount 3330 are collectively referred to as a multi-layer mount. The circumference of every mounting bracket is provided with a plurality of installation positions that are used for placing the filter piece at intervals, take first mounting bracket 3310 as an example, and the circumference of first mounting bracket 3310 is provided with four installation positions 3312 that are used for placing the filter piece at intervals, and second mounting bracket 3320, third mounting bracket 3330 and first mounting bracket 3310 have the same structure, and will not be repeated here. The detecting device 340 is used for detecting whether there are filtering pieces on each installation position, and for the structure of setting up four installation positions on three installation racks, each installation rack, there are 12 installation positions altogether, the detecting device 340 is used for detecting the filtering piece existence condition on 12 installation positions, the detecting device has the preset detection position to detect whether there are filtering pieces on the installation position of preset detection position department, in practical application, the manipulator also usually snatchs the filtering piece of this preset position department and carries out the action of next step.

It should be understood that the number of the mounting frames is not limited to three, but may be two, four, five, etc., as long as it is at least two; the mounting positions on each mounting frame are not limited to four, but may be two, three, five, or the like, as long as they are at least two.

In the beverage filter device 300 of the application, since the beverage filter device is provided with the plurality of layers of mounting frames, a plurality of mounting positions for placing the filter are arranged on each layer of mounting frames, the number of the filter which can be placed is large, and the filter can be assembled after the filter is not arranged on all the mounting positions by combining the arrangement of the detection device 340, an operator can complete a plurality of orders once assembling; in addition, an operator can flexibly supplement the filter element according to the idle time of the operator, so that the time cost of the operator can be greatly saved.

It should be noted that, although in the embodiment shown in fig. 1, the support rod 310 is a rod disposed vertically, in practical application, the support rod 310 may further include a first rod disposed horizontally, and one end of the first rod is connected to the first mounting rack 3310, the second mounting rack 3320 and the third mounting rack 3330 through a second rod disposed vertically. That is, the structure of the support bar 310 is not limited as long as it can support the multi-layered mounting frame. The support rod 310 may be fixed or rotatable, and in the case of fixed, only the motion of the mechanical arm 400 is planned to grasp the filter element.

In order to simplify the motion planning of the mechanical arm 400, the support rod 310 may be driven to rotate, the beverage filter device 300 further includes a driving element 320, the driving element 320 is configured to drive the support rod 310 to rotate so as to drive all the mounting frames to synchronously rotate around the support rod 310, so that the next mounting positions of all the mounting frames can be located at the corresponding preset element positions at the same time, when the beverage filter device 300 is applied to the beverage making apparatus, the preset element positions correspond to the preset detection positions of the detection device 340 and the position where the mechanical arm grabs the filter element, specifically, the driving element 320 is connected with the support rod 310 and can drive the support rod 310 to rotate, and the driving element 320 is, for example, a motor. Based on the arrangement of the driving member 320, the multi-layered mounting frame can be rotated, thereby facilitating the robot arm 400 to grasp the filter member at a fixed position (i.e., a preset member position) of the same layer.

As an exemplary embodiment, the beverage filtering device 300 further includes a detecting device 340, where the detecting device 340 includes a fixing piece 3410 and a plurality of detecting sensors 3420, the fixing piece 3410 is disposed beside the supporting rod 310, and each detecting sensor 3420 corresponds to a mounting frame for detecting whether the filtering device is located at the mounting position of the preset taking position.

Specifically, the fixing member 3410 may be a fixing column, and the plurality of detecting sensors 3420 are disposed at intervals along a length direction of the fixing column, where the number of detecting sensors 3420 is equal to the number of mounting frames, and each detecting sensor 3420 corresponds to one mounting frame. For the embodiment shown in fig. 1, three detection sensors 3420 are respectively disposed corresponding to the upper mounting frame 3310, the middle mounting frame 3320 and the lower mounting frame 3330, each detection sensor 3420 is configured to detect whether there is a filter on the mounting position at the position right in front of the detection sensor 3420 (i.e., the preset position), and a detection signal can be fed back to the controller, so that the controller can control the driving member 320 to drive the supporting rod 310 to rotate the next mounting position to the preset position when the preset position is determined to have no filter according to the detection signal, and the controller can conveniently control the mechanical arm 400 to grasp the filter when the preset position is determined to have a filter according to the detection signal. The controller may be a common PLC controller, and will not be described in detail herein.

In the embodiment shown in fig. 1, the 4 mounting positions on the upper mounting frame 3310, the 4 mounting positions on the middle mounting frame 3320 and the 4 mounting positions on the lower mounting frame 3330 are aligned in the vertical direction, that is, each mounting position on all mounting frames is aligned one by one in the length direction of the supporting rod 310 to form a plurality of rows of mounting positions, and the driving member 320 is used for driving the supporting rod 310 to rotate so as to drive all mounting frames to synchronously rotate along the supporting rod 310, so that each row of mounting positions is simultaneously located at the corresponding preset member position. To achieve the above object, it is only required to satisfy: all the mounting frames rotate along the rotation direction to reach the condition that the rotation angles of the respective preset picking member positions are consistent. The specific implementation manner of the embodiment is as follows: the plurality of mounting locations on each mounting rack 3310 may be circumferentially spaced and evenly arranged, as shown in fig. 4, such that the rotation angle between two adjacent mounting locations is 90 °, and thus, the driving member 320 rotates the plurality of mounting racks synchronously 90 ° each time, so that the next row of mounting locations may be located at the respective corresponding preset position. Of course, in practical applications, the plurality of mounting positions of each mounting rack 3310 may be circumferentially spaced but unevenly disposed (for example, the rotation angle of the two mounting positions connected to each mounting rack may be any angle such as 20 °, 50 °), and since each mounting position on all mounting racks is aligned one by one in the length direction of the support rod 310, each time the driving member 320 drives the corresponding rotation angle, the next row of mounting positions can be located at the respective corresponding preset member positions.

It should be noted that, although in the present embodiment, in the case that each mounting position on all the mounting frames is aligned one by one in the length direction of the support rod 310 to form a plurality of columns of mounting positions, the fixing member 3410 may be a plurality of fixing members and a fixing plate, in practical application, the plurality of detecting sensors 3420 may be a plurality of fixing members, and the driving member 320 may drive the plurality of mounting frames to rotate synchronously and make each column of mounting positions be located at the corresponding preset member positions simultaneously.

It should be noted that, in practical application, it is also possible to: each of the mounting locations on all of the mounting frames is not aligned one by one in the length direction of the support bar 310, for example, 4 mounting locations on the upper filter cup tray set 3310, 4 mounting locations on the middle filter cup tray set 3320, and 4 mounting locations on the lower filter cup tray set 3330 may not be aligned in the vertical direction, and the three detection sensors 3420 may not be aligned in the same vertical line. At this time, the number of the fixing members 3410 may be plural, and the fixing members may be used for installing different detecting sensors 3420, and of course, one detecting fixing plate may be provided to install plural detecting sensors 3420 not on a vertical line at the same time, and in any case, the driving member 320 may drive plural mounting frames to rotate synchronously and enable the next mounting positions of all the mounting frames to be located at the respective corresponding preset member positions at the same time.

In addition, although in the above various implementations, the driving member 320 is used to drive all the mounting frames to rotate synchronously, but the application is not limited thereto, and in practical applications, the driving member 320 may be used to drive the supporting rod 310 to rotate so as to drive each mounting frame to rotate independently along the supporting rod 310, so that the mounting position on each mounting frame can rotate independently to the preset picking position; in order to facilitate the driving member 320 to independently rotate the current mounting frame by a preset angle so that the mounting position on each mounting frame can independently rotate to a preset member taking position, the stay bar 310 can comprise a plurality of sections of rod parts, every two adjacent sections of rod parts are rotationally connected, correspondingly, the driving member 320 comprises a plurality of driving motors, each section of rod part is connected with one driving motor, and the driving motors respectively correspond to the mounting frames one by one.

As an exemplary embodiment, for each column of mounting positions can be located at the corresponding preset position at the same time, the beverage filter unit 300 further includes an origin correction device 350, where the origin correction device 350 is configured to detect whether the mounting frame returns to the origin when rotating one turn. Specifically, the origin correcting device 350 includes an origin sensor 351 and a detection piece 352, the detection piece 352 having a first position in which the origin sensor 351 is blocked and a second position in which the origin sensor 351 is unseated, and the detection piece 352 being rotatable with the support bar 310 between the first position and the second position, it should be understood that the detection piece 352 may be provided on the support bar 310 for the purpose of rotating with the support bar 310. Thus, the origin correction during one circle of rotation of the mounting frame can be detected, the mounting frame is guaranteed to rotate accurately, the detecting piece 352 rotates along with the mounting frame, the detecting piece 352 blocks the origin sensor 351, and the return to the original position is indicated. For the structure that the mounting position on each mounting frame can be independently rotated to the preset picking position, the beverage filter device 300 may also include an origin correction device 350, where the origin correction device 350 is used to detect whether the beverage filter device returns to the origin when each mounting frame rotates one turn, it should be understood that in this case, a plurality of origin correction devices 350 need to be disposed, and the plurality of origin correction devices 350 respectively correspond to the plurality of mounting frames one by one.

In order to facilitate the installation of the filter, the installation site needs to have a hollow portion, and as shown in fig. 4, taking the first installation frame 3310 as an example, the first installation frame 3310 has four installation sites 3312, each installation site 3312 includes an annular structure having a hollow portion 33121, and the hollow portion 3312 is disposed in a vertical direction, so that the hollow portion 3312 of the installation site 3312 is vertical (or disposed upward) no matter whether the multi-layered installation frame 3310 is disposed along a horizontal direction or a vertical direction at equal intervals, so that the filter can be well supported.

In practical application, the installation positions on the same installation frame are used for placing the same filter element; the mounting locations on the different layers of mounting frames are used for placing different filtering pieces. For the structure shown in fig. 1, four mounting locations 3312 (abbreviated as upper mounting locations) on the upper mounting frame 3310 are used for placing 4 identical filter members; four mounting locations (middle mounting locations for short) on middle mounting rack 3320 for placing 4 identical filter elements; four mounting locations (simply referred to as lower mounting locations) on the lower mounting bracket 3330 for placing 4 identical filter elements; the filter piece on the upper mounting position, the filter piece on the middle mounting position, the filter piece on the lower mounting position are different, and the difference of the filter pieces includes: the different sizes (mainly corresponding to the size of the coffee amount and the size of the cup in the order information) and the different merchants (different manufacturers of filter papers adopted for different coffee varieties) can meet the requirements of different order information. It should be appreciated that in order for the mounting locations on the same mounting frame to be used for placing the same filter, the plurality of mounting locations on the same mounting frame have hollow portions of the same size, so that the filter can be clamped at 1/3-2/3 height positions of the filter when placed in the hollow portions, thereby facilitating the robotic arm 400 to grasp the same type of filter on the mounting locations on the same mounting frame.

It should be appreciated that the spacing between the upper stage mount 3310 and the middle stage mount 3320 is adjustable and the spacing between the middle stage mount 3320 and the lower stage mount 3330 is also adjustable in order to accommodate different filters.

Further, for each mounting rack, at least two mounting positions are uniformly spaced along the circumference of the mounting rack, and still taking the upper mounting rack 3310 as an example, as shown in fig. 4, the upper mounting rack 3310 has a central position 3311, the support rods 310 are arranged on the central position 3311 in a penetrating manner, and four mounting positions 3312 are uniformly distributed on the circumference with the central position 3311 as the center, so that four mounting positions 3312 are uniformly spaced along the circumference of the mounting rack. In this way, the rotation angle of the mounting rack 3311 is conveniently controlled. Thus, when the multi-layered mount 3311 rotates synchronously, the angle of each rotation is uniform; or the multiple-layer mount 3311 does not rotate synchronously, the angle of rotation of each layer is also uniform.

In the application, the filter piece is filter paper, and the mechanical arm directly grabs the filter paper and places the filter paper in the filter cup of the brewing frame. Of course, in practical application, the filter cup with the filter paper can also be directly placed on the installation position to serve as a filter piece, so that the filter cup with the filter paper can be directly grabbed by the manipulator and placed on the brewing frame.

The present application further provides a beverage making apparatus, as shown in fig. 5, where the beverage making apparatus includes a beverage filter unit 300, a mechanical arm 400, and a controller (not shown in the controller, as described above, the controller may be a common PLC controller, which will not be described in detail herein), the beverage filter unit 300 is a beverage filter unit device described above, and in addition to the beverage making apparatus, the beverage filter unit 300, the mechanical arm 400, and the bean grinder unit 500 may be disposed on the operation table 200, and the mechanical arm 400, the bean grinder unit 500, and the controller may have various structures that may be present or may occur in the future, which do not limit the scope of protection of the present application. The detecting device 340 of the beverage filtering piece device 300 is configured to detect whether a filtering piece exists on each installation position, and send a detection signal to the controller; the controller determines according to the detection signal, and if there is a filter, the controller controls the mechanical arm 400 to grasp the filter. Since the beverage filter unit 300 has the above-described advantageous effects, the beverage making apparatus including the beverage filter unit 300 must also have the above-described advantageous effects.

In operation of the beverage making apparatus, taking coffee as an example, the robotic arm 400 is capable of grasping the filter on the beverage filter assembly 300 and holding the filter to receive coffee grounds from the grinder assembly 500 under the control of the controller. The control modes of the controller can be various, and the following one by one are described:

first, the controller judges whether a filter exists at a preset filter taking position detected by the current detection sensor according to a detection signal sent by the current detection sensor, and if so, the controller controls the mechanical arm 400 to grasp the filter; if no, judging whether the corresponding preset piece taking position has a filter piece according to the detection signal sent by the next detection sensor, continuing to repeatedly judge, if all the preset piece taking positions are judged to have no filter piece according to all the detection signals, controlling the driving piece 320 to drive the supporting rod 310 to rotate by a preset angle so as to drive all the mounting frames to synchronously rotate around the supporting rod 310, so that the next mounting positions of all the mounting frames can be simultaneously positioned at the corresponding preset piece taking positions, and continuing to repeatedly judge. In order to meet the requirement of the control manner, the beverage filter device 300 may include a deck plate 360, the driving member 320 is disposed on the deck plate 360, the supporting rod 310 has a connection end 311, and the connection end 311 is connected with the driving member 320 through the deck plate 360, so that the plurality of mounting frames synchronously rotate, and after one row is grabbed, the next row is grabbed, so that the working efficiency can be improved.

And, the controller may also determine the current sensor and the next detection sensor in a preset order. For example, the robotic arm 400 may be grasped from top to bottom, or from bottom to top. With the drink filter device 300 with three detection sensors 3420 shown in fig. 1, if the detection signals of the three detection sensors 3420 indicate that there is no filter, the driving member 320 is controlled to rotate by a certain angle to make the three mounting positions of the other row reach the detection position until the filter on the three mounting positions is completely grabbed, and the operation is repeatedly performed until the driving member 320 rotates to make the mounting positions of all rows reach the detection position, and when all the filters are completely grabbed, an alarm prompt is sent to inform an operator that the filter should be replenished.

Second, the controller is configured to determine whether a filter is present at the preset position according to a detection signal sent by a detection sensor corresponding to the current mounting frame, if so, control the mechanical arm 400 to grasp the filter, and if not, control the driving element 320 to drive the current mounting frame to independently rotate by a preset angle so that the next mounting position is located at the preset position, and continue to repeatedly determine, if the determination result from each mounting position on the current mounting frame to the preset position is that no filter is present, the controller reads the detection signal sent by the detection sensor corresponding to the next mounting frame, and repeatedly determine based on the detection signal.

Third, a controller is provided with: the corresponding relationship of the filter element carried on each mounting bracket. The controller receives the order information, determines a corresponding mounting frame according to the order information and the corresponding relation, judges whether a filter exists at a preset filter taking position according to detection signals of a corresponding detection sensor aiming at the determined mounting frame, and if yes, controls the mechanical arm 400 to grasp the filter.

Based on different control modes, when the mechanical arm 400 grabs the filter bowl, any preset part taking position with the filter bowl can be taken to grab the filter bowl, and of course, in practical application, the preset part taking position closest to the mechanical arm 400 can be selected preferentially.

Compared with the prior art, the beverage filter unit device 300 can be used for placing a large number of filter units, so that more orders can be automatically executed after the filter units are supplemented for a single time, and the cost of manual operation time is saved; the filter can be replenished by staff at any time in the free time, and the filter can be replenished after the alarm prompt; and when applied to different sized consoles 200, different numbers of layers and filter element counts per layer may be provided.

In the beverage making apparatus, the beverage filter unit 300 may be embedded on the console 200 through the table panel 360, however, in practical applications, the beverage filter unit 300 may also be packaged as an integrated unit and placed on the console 200.

Overall, the application has the following advantages:

1. because the multi-layer installation rack is arranged on each layer, the number of the filtering pieces which can be placed is large, and an operator can complete a plurality of orders once assembling, so that the time cost of the operator can be greatly saved.

2. Due to the adoption of the multilayer synchronous rotation scheme, after one row is grabbed, the next row is grabbed by rotating, and therefore the working efficiency can be improved.

3. Due to the adoption of the driver and the rotating structure, compared with the scheme of one grabbing position of each filter element, the grabbing difficulty of the mechanical arm 400 is reduced, and the space is saved.

4. Due to the adoption of the multilayer rotary structure, the detection sensor is used for circulating detection, so that a worker can supplement any number of filter elements on the installation position at any time without following a certain rule of supplementing the filter elements, and the use of equipment and the operation of a store are greatly facilitated.

5. Since the spacing (i.e., height) between the layers is adjustable, different sized filter elements can be conveniently accommodated.

6. The number of filter elements stored per layer and the number of layers may be defined differently depending on the size of the console 200, so as to provide a moderate overall size of the beverage filter element assembly 300 on the console 200.
