Note that the empty cup weighing tray assembly 904 has a tray for receiving the cup in the placing hole 201, a driver for driving the tray to rise to receive the cup, and a load cell for measuring the weight of the cup when the tray receives the cup. Specifically, when the resting plate 20 moves above the empty cup weigh tray assembly 904 (i.e., the placement hole 201 of the resting plate 20 corresponds to the position of the tray in the empty cup weigh tray assembly 904), the driver in the empty cup weigh tray assembly 904 drives the tray up motion to accept the cup while the load cell measures the weight of the cup. Wherein, the driver of the empty cup weighing tray assembly 904 can be connected with the controller 907, and the controller 907 can control the driver of the empty cup weighing tray assembly 904 to drive the tray to move upwards to accept the cup body in the placing hole 201 when the placing hole 201 of the placing plate 20 corresponds to the position of the tray in the empty cup weighing tray assembly 904. The full cup weighing cup holder assembly 906 has the same structural composition and weighing principle as the empty cup weighing cup holder assembly 904, and thus, detailed description thereof is omitted. Corresponding drivers for controlling the up-and-down movement of the empty cup weighing tray assembly 904 and the full cup weighing tray assembly 906 are respectively formed in the corresponding driving boxes 40.
The filling head 30 may be configured with a group of (i.e. two or more) discharge ports, that is, two or more conical pipes 302 arranged in parallel with a central axis (i.e. a longitudinal central axis of the conical pipe 302) at a lateral interval may be configured below the metering conical hopper 304, each conical pipe is correspondingly connected with a straight pipe 303, the end face of each straight pipe 303 is covered with a pressing head 301, the number of cups in the densification cup holder assembly 905 is the same as the number of the pressing heads 301, and the positions of the cups in the densification cup holder assembly 905 are opposite to the pressing head 301. The number of placing holes 201 formed by the resting plates 20 is the same as the number of discharge openings of the filling heads 30.
The filling platform of this embodiment controls the shelving plate 20 to move along the target direction in a circulating manner through a controller 907 based on a command formed by target input, and sequentially controls the empty cup weighing cup supporting assembly 904 to perform empty cup weighing on the cup body on the shelving plate 20 above the empty cup weighing assembly in a circulating manner, controls the filling head 30 above the density cup supporting assembly 905 to fill the cup body below the filling head, and controls the full cup weighing cup supporting assembly 906 to perform full cup weighing on the cup body above the full cup weighing cup supporting assembly, so as to determine whether the screw 307 in the filling head is matched with the filling powder according to multiple sets of performance data of the filling head 30 obtained by the weight of the empty cup measured by the empty cup weighing cup supporting assembly 904 and the weight of the full cup measured by the full cup weighing cup supporting assembly 906. So, the filling platform of this embodiment carries out the filling powder to the cup through obtaining with filling powder assorted screw 307, can effectively improve the filling effect of powder. From this, this embodiment has solved because the screw rod is relatively poor with the powder suitability of filling and leads to the problem that the filling effect is relatively poor.
The filling platform of this embodiment further includes a powder flowability tester 908 configured to obtain a plurality of sets of flowability data of the powder filled into the cup located below the filling head by the filling head 30, and the controller 907 determines the matching between the screw 307 in the filling head and the filling powder according to the plurality of sets of flowability data and the plurality of sets of performance data. So, combine filling head 30 to carry out the distribution data of the powder volume of filling and filling head in to the multiunit cup simultaneously and the data such as compression performance of screw to the powder, confirm whether screw and the powder that fills match to further improve filling head in screw 307 and the matching nature of filling powder, thereby ensure to obtain further promotion according to the filling effect when screw 307 that confirms carries out the filling to the powder.
Further, the controller 907 may be further configured to obtain multiple sets of filling times for the filling head 30 to fill the cup with the powder, and determine the matching between the screw 307 in the filling head and the filling powder based on the multiple sets of performance data and the multiple sets of filling times, or determine the matching between the screw in the filling head and the filling powder according to the multiple sets of performance data, the multiple sets of flowability data, and the multiple sets of filling times. So set up, the filling platform of this embodiment combines multiunit performance data and multiunit filling time simultaneously through controller 907, or combines multiunit performance data, multiunit mobility data and multiunit filling time simultaneously and confirms and fill the powder with filling powder assorted screw rod and carry out the filling, can guarantee the filling efficiency to the powder under the prerequisite that further improves powder filling effect, prevents that filling speed is slower and the lower problem of work efficiency who leads to the complete machine from taking place.
In any of the above embodiments, the controller 907 may further control the placement plate 20 to move cyclically between the positions above the density cup holder assembly 905 and the position above the full cup weighing cup holder assembly 906, so as to control the filling head above the density cup holder assembly 905 to fill the cup body below the filling head and to perform full cup weighing on the cup body after being filled with the powder, and adjust the powder discharge amount of the filling head 30 according to a weight difference between an empty cup weight of the cup body and a full cup weight measured by the full cup weighing cup holder assembly 906.
It should be understood that, the filling platform of this embodiment adjusts the powder discharge amount of the filling head 30 by the weight difference of the cup empty cup weight measured in the process of detecting the matching between the screw 307 and the powder and the full cup weight measured in the process of controlling the shelving plate 20 to circularly move between the positions above the densification cup supporting assembly 905 and the full cup weighing cup supporting assembly 906, so that the powder discharge amount of the filling head 30 during filling the cup is maintained within a specified range, thereby improving the accuracy of powder filling, and ensuring the filling quality and the filling efficiency of the powder. From this, the filling platform of this embodiment has solved the filling mechanism among the prior art and has been difficult to control the filling precision and lead to the relatively poor problem of filling quality.
Further, the controller 907 is configured to: based on the relationship between the weight difference and the preset weight difference range, the number of turns of the screw 307 in the filling head is adjusted to adjust the powder discharge amount of the filling head 30. Specifically, if the weight difference value is higher than the upper limit value of the difference range of the preset weight, the number of turns of the screw is reduced; and if the weight difference value is lower than the lower limit value of the preset weight difference range, increasing the rotation turns of the screw. The preset weight difference range may be set based on actual working condition requirements or conventional standards, which will not be described in detail. The driving assembly 3091 is connected with the controller 907 to control the driving assembly 3091 to drive the filling head 30 to fill the cup body with the adjusted powder discharge amount through the controller 907, and specifically, the controller 907 controls the driving assembly 3091 to drive the screw 307 in the filling head 30 to rotate with the adjusted number of rotations, so as to adjust the powder discharge amount of the filling head 30. So set up, adjust the number of turns of screw rod according to the relation of weight difference value and predetermineeing the weight difference scope through controller 907, make the screw rod rotate with the number of turns after the adjustment, ensure that the powder load of filling head 30 is in the specified range to can ensure the filling precision of filling platform to the cup.
In the above embodiment, the densification cup assembly 905 is configured such that the cup in the placement hole 201 is lifted up to move toward the end of the straight tube 303 when the resting plate 20 is controllably moved below the end of the straight tube 303. Specifically, the densification cup holder assembly is configured to lift the cup body to a first predetermined height for the filling head 30 to fill the cup body with powder or to lift the cup body to a second predetermined height for the pressing head 301 to compact the powder in the cup body. Wherein the first preset height is lower than the second preset height. A driver for controlling the up and down movement of the densifying cup assembly 905 is formed in the driving box 40. The structure composition of the densification cup holder assembly 905 is the same as that of the empty cup weighing cup holder assembly 904, and is different from that of the empty cup weighing cup holder assembly 904 in that when the densification cup holder assembly 905 is configured to fill the cup body with powder through the filling head 30, a driver in the densification cup holder assembly 905 is controlled by the controller 907 to drive the corresponding cup holder to ascend by a first preset height, or when the powder in the cup body is compacted through the pressing head 301, the driver in the densification cup holder assembly 905 is controlled by the controller 907 to drive the corresponding cup holder to ascend by a second preset height. When detecting that the placement plate 20 is controllably moved to the lower part of the tail end of the straight pipe 303, the controller 906 controls the densification cup supporting assembly 905 to support the cup body to rise to a first preset height, and controls the densification cup supporting assembly 905 to support the cup body to rise to a second preset height after powder is filled, so that the pressing head can press the powder in the cup body. The densification cup holder assembly 905 can also lift the cup body to a first preset height when detecting that the shelving plate 20 is controllably moved to the position below the tail end of the straight pipe 303, and lift the cup body to a second preset height after powder filling.
It should be understood that, when the filling head 30 fills the powder in the cup, the densification cup supporting assembly is configured to support the cup to rise to a first preset height, so that the rim of the cup is close to the end of the filling head 30, and the filling head 30 is convenient to reliably fill the powder in the cup when extruding the powder, thereby reducing the filling environment deterioration caused by the powder sprinkled on the outer side of the rim of the cup and the rim of the cup due to the error of the relative position between the filling head 30 and the rim of the cup. Stop to carry out the filling to the cup at filling head 30 and need press the real-time to the powder in the filling back cup, the densification holds in the palm the cup subassembly configuration and rises to the second and predetermine the height, and this second is predetermine highly to be greater than first predetermined height, so that the terminal press head 301 of filling head 30 stretches into to the interior powder surface of cup, through press head 301 flattening reliably and press the interior powder of cup, improve the roughness on powder surface in the cup and increase the density of the interior powder of cup, thereby improve the filling effect of filling head 30 to the interior powder of cup.
It can be seen from this that, the filling platform of this embodiment holds up the cup through the densification and rises to first preset height to fill the powder to the cup through the filling head 30 of corresponding position, and hold up the cup through the densification and rise to the second preset height, carry out the compaction to the powder in the cup through the last pressing head 301 of the filling head of corresponding position, thereby accomplish through same densification support cup subassembly and carry out the purpose that fills the powder and carry out the densification to the filling powder to the cup. Therefore, the filling platform of the embodiment can not only fill and compact the powder, but also greatly simplify the structure of the filling platform due to the fact that the powder and the compacted powder are filled in the cup body through the same densifying support cup assembly. Therefore, the problems that the filling platform in the prior art needs to be provided with the filling mechanism and the densifying mechanism independently, so that the whole machine is complex in structure and large in size are solved.
Referring to fig. 9 and 10, the present embodiment further provides a method for detecting screw adaptability, which may include:
and 802, controlling the transverse sliding of the mounting frames 902 which are correspondingly mounted on the two mounting plates 901, so that the filling head 30 which is assembled between the two supporting beams 903 is removed from between the two mounting plates 902.
And 804, controlling the discharging of the filling head 30 and detecting the discharging state of the filling head 30. Wherein the operation of detecting the discharge state of the filling head 30 comprises: whether or not an abnormality occurs in the output powder of the filling head 30 is detected by a sensor 909 disposed at the filling head 30. The abnormal powder output of the filling head 30 includes: the powder in the filling head has the conditions of blocking, blocking or slipping.
Fig. 11 is a schematic graph of the discharge of the filling head as a function of time, wherein the discharge N of the filling head is shown on the ordinate and the discharge time T of the filling head is shown on the abscissa. It can be understood that the discharge amount N (t) of the filling head is between N2 and N1, which means that the discharge amount of the filling head is within a normal setting range, that is, the screw 307 in the filling head is matched with the filled powder; on the contrary, the powder output by the filling head is abnormal, that is, the screw 307 is not adapted to the filled powder, at this time, the screw 307 needs to be replaced, and the discharge amount N (t) of the filling head is in the range of N2 to N1 by the replaced screw, N2 represents the lowest preset threshold, N1 represents the highest preset threshold, and the settings of the lowest preset threshold N2 and the highest preset threshold N1 can be designed according to the inherent properties of different powders, which is not described in detail herein. Referring to fig. 11, in the time period from T1 to T2, the discharge amount N (T) of the filling head is lower than the minimum preset threshold value N2, which indicates that the filling head is jammed. In the time period from T3 to T4, the discharge amount N (T) of the filling head is 0, which indicates that the filling head is not discharged, namely the phenomenon of material blockage occurs. And in the time period from T5 to T6, the discharge amount N (T) of the filling head is higher than the highest preset threshold value N1, which indicates that the filling head has a material slipping phenomenon. It can be seen that the filling heads corresponding to the time periods from T1 to T2, from T3 to T4 and from T5 to T6 all show abnormal powder output, and when one of the abnormal powder output occurs, the screw in the filling head can be replaced so that the discharge amount of the filling head is in the range from N2 to N1.
The sensor 909 may be configured as a solid flow meter to detect the discharge amount of the filling head through the solid flow meter configured at the filling head, so as to detect whether the powder output by the filling head is abnormal in real time. Referring to fig. 4, when the solid flow meter detects that the powder output from the filling head is abnormal, an abnormal signal is fed back to the controller 907, and the alarm 910 is controlled by the controller 907 to warn. It should be noted that the process or method for detecting the discharged powder amount by the solid flow meter is well known to those skilled in the art, and will not be described in detail here.
And 806, determining the adaptability of the screw 307 in the filling head and the filling powder according to the discharging state of the filling head 30. Specifically, if the output powder of the filling head 30 is not abnormal, the screw 307 in the filling head 30 is adapted to the filling powder.
The method for detecting the suitability of the screw rod of the embodiment controls the transverse movement of the mounting frame 902 correspondingly mounted on the two mounting plates 901, so that the filling head 30 mounted between the two supporting beams 903 is moved out from between the two mounting plates 901, and then controls the discharging of the filling head 30 to determine whether the screw rod 307 in the filling head is matched with the filling powder according to the detected discharging state of the filling head. Therefore, the method for detecting the suitability of the screw is simple and easy to operate, the suitability of the screw and the filling powder can be quickly and effectively determined by detecting the discharging state of the filling head, and a user can replace the screw which is not adapted to the filling powder in time, so that the subsequent efficiency of filling the powder is improved. Therefore, the method for detecting the suitability of the screw rod solves the problem that the filling effect is extremely poor due to poor suitability of the screw rod and the filled powder in the prior art.
Further, in the embodiment of fig. 12, the method for detecting screw suitability further includes:
and 1102, controlling the mounting frame 902 to slide transversely so that the filling head 30 assembled between the two supporting beams 903 moves to the position between the mounting plates 902.
And 1104, responding to the target input, controlling the shelving plates 20 transversely arranged on the plurality of mounting plates arranged in parallel at intervals to circularly move along the target direction, wherein the shelving plates 20 pass through the empty cup weighing tray assembly 904 (corresponding to an empty cup weighing station), the density increasing tray assembly 905 (corresponding to a filling station) and the full cup weighing tray assembly 906 (corresponding to a full cup weighing station) in sequence in the process of moving along the target direction.
The cup bodies positioned at different stations (namely, an empty cup weighing station corresponding to the empty cup weighing tray assembly 904, a filling densification station corresponding to the densification tray assembly 905 and a full cup weighing station corresponding to the full cup weighing tray assembly 906) can move along the length direction of the screw rod seat 101 under the action of the controlled movement of the screw rod 102 through the placing plate 20, so that the aim of moving the cup bodies to the corresponding positions is fulfilled.
And 1106, sequentially and circularly controlling the empty cup weighing cup supporting assembly 904 to perform empty cup weighing on the cup body on the placing plate above the empty cup weighing cup supporting assembly, the filling head 30 above the densifying cup supporting assembly 905 to fill the cup body below the filling head, and the full cup weighing cup supporting assembly 906 to perform full cup weighing on the cup body above the full cup supporting assembly.
It should be noted that, in the process of weighing empty cups, filling powder and full cups of a group of cups in the placing hole 201 formed on the placing plate 20, the placing plate 20 needs to drive the cups to move from the front end of the empty cup weighing station and sequentially pass through the empty cup weighing station, the filling station and the full cup weighing station, and after weighing empty cups, filling powder and full cups of a group of cups respectively, a group of performance data of the filling head 30 can be obtained, and meanwhile, the placing plate 20 returns to the initial position (i.e. the position at the front end of the empty cup weighing station) to enter the step of weighing empty cups, filling powder and full cups of the next group of cups to obtain the next group of performance data of the filling head 30. Thereby, the operation is cycled to acquire sets of performance data of the filling heads 30.
And step 1110, determining the matching of the screw 307 in the filling head and the filling powder based on the multiple groups of performance data. The performance parameters of the filling head of the embodiment mainly include filling stability, which can be interpreted as distribution data of the amount of powder filled into the plurality of groups of cup bodies by the filling head. The specific content of step 1110 may include: the screw 307 in the filling head matches the filling powder when the filling stability is within the preset stability value range. The preset stable value range can be set according to experience values obtained by experiments or repeated operations and according to specific actual working conditions, which is not described in detail.
The method for detecting the suitability of the screw rod in the embodiment controls the shelving plate to move along the target direction in a circulating manner based on an instruction formed by target input, and sequentially controls the empty cup weighing cup supporting assembly to perform empty cup weighing on the cup body on the shelving plate above the empty cup weighing cup supporting assembly in a circulating manner, the filling head above the densification cup supporting assembly to perform filling on the cup body below the filling head, and the full cup weighing cup supporting assembly to perform full cup weighing on the cup body above the full cup weighing cup supporting assembly, so that whether the screw rod in the filling head is matched with filling powder or not is determined according to multiple groups of performance data of the filling head obtained by the empty cup weight measured by the empty cup weighing cup supporting assembly and the full cup weight measured by the full cup weighing cup supporting assembly. Therefore, the method for detecting the suitability of the screw rod can effectively improve the powder filling effect by acquiring the powder filling state of the cup body by the screw rod matched with the powder filling state. From this, this embodiment has solved because the screw rod is relatively poor with the powder suitability of filling and leads to the problem that the filling effect is relatively poor.
To further improve the matching degree between the determined screw and the filled powder, the method for detecting screw suitability of the present embodiment may include, before step 1110:
and 1108', acquiring multiple groups of flowability data of the powder filled into the cup body below the filling head by the filling head 30. Step 1110 may be specifically configured to: the matching of the screw 307 in the filling head with the filling powder is determined based on the sets of flowability data and the sets of performance data. The flowability data of the powder can be obtained by testing parameters such as compression performance of the screw 307 on the powder in the filling head 30 based on a special powder flowability tester. Specifically, the screw 307 in the filling head matches the filling powder when the filling stability is within the preset stable value range and the compression property of the filling powder is within the preset flow value range. So, combine filling head 30 to carry out the distribution data of the powder volume of filling and filling head in to the multiunit cup simultaneously and the data such as compression performance of screw to the powder, confirm whether screw and the powder that fills match to further improve filling head in screw 307 and the matching nature of filling powder, thereby ensure to obtain further promotion according to the filling effect when screw 307 that confirms carries out the filling to the powder. It is noted that step 1008' may follow step 1108, as shown in fig. 13. As shown in FIG. 14, step 1108' may also precede step 1108.

and 1402, acquiring multiple groups of filling time of the filling head 30 for filling the powder into the cup body.
And 1404, determining the matching of the screw 307 in the filling head and the filling powder based on the multiple groups of performance data and the multiple groups of filling time.
So set up, acquire with filling powder assorted screw 307 carry out the filling powder to the cup under the prerequisite of guaranteeing powder filling effect, can effectively improve the efficiency of carrying out the filling to the powder, prevent that filling speed is slower and lead to the work efficiency of complete machine lower.
In another embodiment of the present invention, as shown in fig. 16, the method for detecting screw suitability further comprises:
and 1402' acquiring multiple groups of filling time for filling the powder into the cup body by the filling head.
And 1404' determining the matching of the screw in the filling head and the filling powder based on the multiple groups of performance data, the multiple groups of flowability data and the multiple groups of filling time.

As shown in fig. 17, this embodiment further provides a powder filling method, including:
the mounting block 902 is controlled to slide laterally 1102 so that the filling head 30 fitted between the two support beams 903 moves between the mounting plates 902.
And 1104, responding to the target input, controlling the shelving plates 20 transversely arranged on the plurality of mounting plates arranged in parallel at intervals to circularly move along the target direction, wherein the shelving plates 20 pass through the empty cup weighing tray assembly 904 (corresponding to an empty cup weighing station), the density increasing tray assembly 905 (corresponding to a filling station) and the full cup weighing tray assembly 906 (corresponding to a full cup weighing station) in sequence in the process of moving along the target direction.
And step 1106, sequentially and circularly controlling the empty cup weighing and supporting assembly 904 to perform empty cup weighing on the cup body on the placing plate above the empty cup weighing and supporting assembly, the filling head 30 above the thickening and supporting assembly 905 to fill the cup body below the filling head, and the full cup weighing and supporting assembly 906 to perform full cup weighing on the cup body above the full cup weighing and supporting assembly.
And step 1110, determining the matching of the screw 307 in the filling head and the filling powder based on the multiple groups of performance data.

From this, this embodiment has solved because the screw rod is relatively poor with the powder suitability of filling and leads to the problem that the filling effect is relatively poor.
As shown in fig. 18, after step 1112, comprising:
And 1116, adjusting the powder discharge amount of the filling head 30 based on the weight difference between the empty cup weight measured by the empty cup weighing tray assembly 904 and the full cup weight measured by the full cup weighing tray assembly 906. It should be understood that when powder is filled into a plurality of groups of cups, the shapes of the cups and other parameters (such as the empty cup mass) are the same, so in this embodiment, when the cups are filled through the determined screw rods matched with the filled powder, the placing plate 20 is moved between the filling station and the full cup weighing station to fill the cups and weigh the full cups, and the placing plate 20 is not moved to the empty cup weighing station, so that the filling efficiency of the filling head on the cups is further improved. The controller 907 may derive a weight difference based on the weight of the empty cup measured at step 1106 and the weight of the full cup measured in real time.
The specific operation process of step 1116 includes: based on the relationship between the weight difference and the preset weight difference range, the number of turns of the screw 307 in the filling head is adjusted to adjust the powder discharge amount of the filling head 30. Specifically, if the weight difference value is higher than the upper limit value of the difference range of the preset weight, the number of rotations of the screw 307 is reduced. If the weight difference is lower than the lower limit of the preset weight difference range, the number of turns of the screw 307 is increased.
In the powder filling method of this embodiment, the powder discharge amount of the filling head 30 is adjusted by the weight difference between the empty cup weight measured in step 1106 and the full cup weight measured in real time, so that the powder discharge amount when the filling head 30 fills the cup body is maintained within a specified range, the powder filling precision is improved, and the powder filling quality and the powder filling efficiency are ensured. Therefore, the powder filling method of the embodiment solves the problem that filling quality is poor due to the fact that a filling mechanism in the prior art is difficult to control filling precision.

Wherein the first preset height is lower than the second preset height.
So, this embodiment is when filling the powder, shelve the top that board 20 moved to densification support cup subassembly 905 through control, then hold up the cup through control densification support cup subassembly 905 and rise to first preset height, and the filling head 30 of corresponding position is to the cup filling powder. After the powder is filled, the embodiment holds up the cup body to rise to a second preset height higher than the first preset height by controlling the densification supporting cup assembly 905, so that the pressing head 301 at the tail end of the filling head at the corresponding position compacts the powder in the cup body, and therefore the purposes of filling the powder in the cup body and densifying the filled powder are achieved through the same densification supporting cup assembly. Therefore, the embodiment can not only fill and compact the powder, but also greatly simplify the structure of the filling platform due to the fact that the powder and the compacted powder are filled in the cup body through the same densifying support cup assembly. Therefore, the problem that the filling mechanism and the densifying mechanism are required to be arranged separately in the prior art, so that the whole machine is complex in structure and large in size is solved.
