[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0052] The invention provides a supply device for conveying materials.

[0053] Please refer to Figures 1 to 3 ,In one embodiment of the present invention, a material conveying supply device includes: a first conveying device 1;

[0054] A directional material guide structure 2, comprising a first motor 21, a mounting cylinder 22, a guide ring 24, and a plurality of material trough structures 25. The mounting cylinder 22 is suspended above the first conveying device 1, the first motor 21 is mounted on the mounting cylinder 22, the guide ring 24 is mounted on the output shaft 23 of the first motor 21 via a connecting arm 231, and is located inside the mounting cylinder 22. A plurality of material trough structures 25 are arranged around the guide ring 24, and the material trough structure 25 only allows one or a row of tablets 10 to be placed.

[0055] The top and bottom of the installation cylinder 22 are connected to a feeding frame 222 and a discharging frame 221 respectively. The upper portion of the installation cylinder 22 is provided with a detection port 223.

[0056] A first detection member 4, wherein the detection end of the first detection member faces the detection port 223;

[0057] a second detecting member 5 , wherein a detecting end of the second detecting member 5 faces the conveying surface of the first conveying device 1 ;

[0058] The material storage structure 3 is used to convey the tablets 10 to the feeding frame 222 .

[0059] Among them, the tablets 10 in the storage structure 3 fall into the feeding frame 222, the first motor 21 drives the output shaft 23 to rotate, and the output shaft 23 drives the guide ring 24 to rotate through the connecting arm 231, so that the material chute structure 25 is aligned with the feeding frame 222, and the tablets 10 located in the feeding frame 222 enter the material chute structure 25. When the material chute structure 25 carrying the tablets 10 rotates to the detection port 223, the first detection component 4 performs an appearance inspection on one side of the tablets 10; when the material chute structure 25 carrying the tablets 10 rotates to be aligned with the unloading frame 221, the tablets 10 fall onto the first conveying device 1 by gravity, and at this time the other side of the tablets 10 faces upward. The first conveying device 1 conveys the tablets 10 to the next process. When the tablets 10 pass through the second detection component 5, the second detection component 5 performs an appearance inspection on the other side of the tablets 10;

[0060] By setting up the directional material guide structure 2, the tablets 10 can be arranged individually or in a row in the material trough structure 25, avoiding the accumulation of tablets 10, making it easier for the first detection component 4 to perform appearance inspection on one side of the tablet 10, and the guide ring 24 drives the tablet 10 to rotate from the top to the bottom through the material trough structure 25 to achieve automatic flipping of the tablet 10. Subsequently, the other side of the tablet 10 is inspected by the second detection component 5, thereby realizing intelligent transportation and appearance inspection of the tablets in production, avoiding the supply of defective products to the coating process or packaging process, etc.

[0061] See also Figure 9The material conveying supply device also includes a control module; the outputs of the first and second detection members 4 are connected to the input of the control module. The drive device (first motor 21) in the directional material guide structure, the conveying module, and the subsequent guide structure drive device (second motor 62) are connected to the output of the control module. The conveying module comprises the first conveying device 1 and the subsequent second conveying device 8.

[0062] The control module is used to control the start and stop of the first conveying device 1, the first motor 21 and the subsequent second motor 62 in the guide structure 6, as well as the operating speed; if the first detection member 4 and the second detection member 5 detect unqualified products, the control module controls the first conveying device 1 and the second conveying device 8 and the first motor 21 to reduce the operating speed, and the second motor 62 drives the material guide box 63 to rotate so that its lower end faces the receiving box 7. After the unqualified product enters the material guide box 63, it slides into the receiving box 7 through the material guide box 63, and then controls the material guide box 63 to rotate and connect the first conveying device 1 and the second conveying device 2 to continue the conveying function; thereby realizing intelligent conveying and detection and rejection of products.

[0063] Among them, both ends of the installation cylinder 22 of the directional material guiding structure 2 are installed on both sides of the bracket of the first conveying device 1 through fixing plates. Of course, a fixing frame can also be set to be installed on the ground, and the installation cylinder 22 is fixed on the fixing frame.

[0064] When the tablet 10 moves to the position of the first detecting element 4 or the second detecting element 5 , the conveyance of the tablet 10 may be slowed down or stopped.

[0065] See also Figure 1 and Figure 2 As an optional method of this embodiment, the second detection member 5 includes a mounting frame 51 and a detection camera 52, the mounting frame 51 is installed on the bracket of the first conveying device 1, and the detection camera 52 is installed on the mounting frame 51.

[0066] The first detection member 4 and the second detection member 5 both include a mounting frame 51 and a detection camera 52 , wherein the mounting frame 51 has a shape corresponding to different installation positions.

[0067] The detection camera 52 is suspended on the first conveying device 1 or above the detection port 223 through the mounting bracket 51. The detection camera 52 in the first detection member 4 collects the appearance information of one side of the tablet 10 through the detection port 223, and the detection camera 52 in the second detection member 5 detects the appearance information of the other side of the tablet 10 conveyed by the first conveying device 1.

[0068] The detection camera 52 is a CCD camera, a CMOS camera, etc.; the number of the detection cameras 52 of the first detection member 4 and the second detection member 5 can be one or more, which is set according to the number of tablets 10 detected each time.

[0069] The appearance inspection system also includes an illumination system (not shown) and a processing module. The illumination system is used to provide supplemental light to the tablet 10 for easier inspection, so that the first inspection member 4 and the second inspection member 5 can better capture images of the tablet 10. The processing module runs the inspection algorithm, processes the image data, and outputs the inspection results.

[0070] See also Figure 5 As a preferred embodiment of this embodiment, one end of the detection port 223 is connected to the bottom end of the feeding frame 222.

[0071] By connecting the detection port 223 with the feed frame 222, when the tablet 10 falls into the interior of the chute structure 25, if the tablet 10 tilts and rests on the inner wall of the chute structure 25, the bottom end of the detection port 223 is connected to the feed frame 222, so that the height of the tablet 10 passing through is increased. Therefore, when the guide ring 24 rotates toward the detection port 223, the bottom of the feed frame 222 is prevented from directly squeezing the tilted tablet 10, causing the tablet 10 to break, etc.

[0072] See also Figure 4 As a preferred embodiment of this embodiment, the material trough structure 25 includes a groove 251, a material box 252, a first elastic member 253 and a convex shaft 254. The groove 251 is opened on the guide ring 24, and the material box 252 is slidably installed in the groove 251, and one end of the material box 252 is connected to the inner wall of the groove 251 through the first elastic member 253, and one end of the convex shaft 254 is installed at the other end of the material box 252. A concave-convex plate 224 is provided on the inner wall of the mounting cylinder 22 and on one side of the feed frame 222. The other end of the convex shaft 254 is aligned with the concave surface of the concave-convex plate 224.

[0073] When the first motor 21 drives the guide ring 24 to drive the material box 252 to move to align with the feed frame 222, the tablets 10 in the feed frame 222 enter the interior of the material box 252, and the guide ring 24 continues to rotate. The convex shaft 254 at one end of the material box 252 acts on the concave and convex surfaces of the concave-convex plate 224 in sequence. When the convex shaft 254 acts on the convex surface, the convex shaft 254 pushes the material box 252 to compress the first elastic member 253. When the convex shaft 254 is aligned with the concave surface, the elastic potential energy of the first elastic member 253 pushes the material box 252 to make the convex shaft 254 abut against the concave surface, so that when the convex shaft 254 passes the concave-convex plate 224, the material box 252 generates reciprocating vibrations. When a tablet 10 tilts against the inner wall of the material box 252, the reciprocating vibration allows the tablet 10 to lie flat in the material box 252, thereby facilitating subsequent appearance inspection by the first detection member 4.

[0074] The length of the concave-convex plate 224 is located between the feed frame 222 and the first detection member 4. The concave surface and the convex surface on the concave-convex plate 224 are preferably concave arc surfaces and convex arc surfaces, and the concave arc surfaces and the convex arc surfaces are staggered and connected;

[0075] In this embodiment, one side of the groove 251 is set as an opening, so that the convex shaft 254 can be aligned with the concave surface of the concave-convex plate 224 through the opening; then both ends of the groove 251 are set as sealed, and at this time the convex shaft 254 passes through the side wall of the groove 251 and is aligned with the concave surface of the concave-convex plate 224.

[0076] One end of the convex shaft 254 facing the concave-convex plate 224 is configured as an arc surface. The first elastic member 253 is preferably a spring, and may also be an elastic member such as a leaf spring.

[0077] Please refer again Figure 4 Preferably, a plurality of partitions are provided inside each material box 252 to divide the material box 252 into a plurality of placement cavities, each placement cavity allowing one tablet 10 to be placed therein. By providing a plurality of placement cavities, overlapping of adjacent tablets 10 can be avoided.

[0078] The inner cavity width of the feed frame 222 only allows the width of one tablet 10 to enter. The feed frame 222 can be used to sort the tablets 10 so that they can enter the material box 252 in a better and orderly manner.

[0079] See also Figure 3 、 Figure 5 and Figure 7As a preferred embodiment of this embodiment, the material storage structure 3 includes a frame portion 31, a V-shaped portion 32 and a driving arm 34. The frame portion 31 is suspended above the mounting tube 22, the top end of the V-shaped portion 32 is slidably connected to the frame portion 31, and the bottom end of the V-shaped portion 32 is slidably connected to the feed frame 222. One end of the driving arm 34 is connected to the V-shaped portion 32, and multiple concave and convex surfaces 241 are arranged around both ends of the guide ring 24, and the concave and convex surfaces 241 are staggered with the grooves 251. The other end of the driving arm 34 passes through the mounting tube 22 and abuts against the guide ring 24. The driving arm 34 and the concave and convex surfaces 241 are located in the same plane.

[0080] The V-shaped portion 32 is provided to facilitate the introduction of the tablets 10 into the feed frame 222. When the first motor 21 drives the guide ring 24 to rotate, the concave-convex surface 241 on the guide ring 24 acts on the driving arm 34. The concave surface and convex surface on the concave-convex surface 241 act on the bottom end of the driving arm 34 in turn. The driving arm 34 drives the V-shaped portion 32 to vibrate up and down. When the vibration is generated, the tablets 10 in the storage structure 3 can better enter the feed frame 222, greatly reducing the problem of blockage of the tablets 10.

[0081] Among them, the number of driving arms 34 is preferably set to two, located at both ends of the V-shaped portion 32, and the corresponding two ends of the guide ring 24 are provided with concave and convex surfaces 241, and the bottom end of the driving arm 34 is embedded with a ball to reduce the friction between the driving arm 34 and the guide ring 24 during interaction.

[0082] The concave and convex surfaces of the concave-convex surface 241 are preferably concave arc surfaces and convex arc surfaces, which are staggered and connected with each other. The concave-convex surface 241 and the groove 251 do not overlap, thereby avoiding the driving arm 34 from interacting with the groove 251.

[0083] A soft rubber portion is provided on the top of the V-shaped portion 32 to prevent damage to the tablet 10 when the V-shaped portion 32 vibrates. The soft rubber portion is made of rubber or silicone.

[0084] Both sides of the frame portion 31 are mounted on both ends of the mounting tube 22 via support plates, or can be mounted on the ground via brackets, wherein the mounting frame 51 in the first detection member 4 is mounted between the two support plates or on the brackets.

[0085] See also Figure 5As a preferred embodiment of this embodiment, the material storage structure 3 also includes an elastic structure 33, which includes an L-shaped frame 331, a positioning shaft 332 and a second elastic member 333. The L-shaped frame 331 is installed on the frame portion 31, one end of the positioning shaft 332 is connected to the V-shaped portion 32, and the other end of the positioning shaft 332 passes through the L-shaped frame 331. The bottom end of the positioning shaft 332 is provided with an end cap, and the second elastic member 333 is sleeved on the positioning shaft 332 and is located between the end cap and the L-shaped frame 331.

[0086] By setting up the elastic structure 33, when the driving arm 34 drives the V-shaped part 32 to move upward, the V-shaped part 32 drives the positioning shaft 332 to lift and compress the second elastic part 333. When the driving arm 34 corresponds to the concave surface, the V-shaped part 32 is lowered by the elastic action of the second elastic part 333 and the gravity of the V-shaped part 32, thereby improving the stability of the V-shaped part 32 during vibration.

[0087] There are multiple elastic structures 33 , which are arranged on both sides of the V-shaped portion 32 .

[0088] The second elastic member 333 is preferably a spring, and may also be an elastic member such as a reed.

[0089] See also Figure 1 As a preferred embodiment of this embodiment, the material conveying supply equipment also includes a second conveying device 8, a guide structure 6 and a receiving box 7. The conveying surface of the second conveying device 8 is lower than the conveying surface of the first conveying device 1. The guide structure 6 includes a mounting plate 61, a second motor 62 and a material guide box 63. The mounting plate 61 is installed on the bracket of the second conveying device 8, the second motor 62 is installed on the mounting plate 61, the material guide box 63 is installed on the drive shaft 64 of the second motor 62, and the material guide box 63 is located at the discharge end of the first conveying device 1 and the feed end of the second conveying device 8. The receiving box 7 is tilted and arranged below the first conveying device 1, and one end of the receiving box 7 extends to the bottom of the material guide box 63.

[0090] Please refer to Figure 8 In (a), when all the tablets 10 are qualified, the first conveying device 1 slides the tablets 10 through the material guide box 63 to the second conveying device 8, and the second conveying device 8 conveys the tablets 10 to the coating process or the packaging process;

[0091] Please refer to Figure 8In (b), when the first detection member 4 or the second detection member 5 detects unqualified tablets, when the unqualified tablets 10 enter the discharge end of the first conveying device 1, the second motor 62 drives the material guide box 63 to rotate counterclockwise by a preset angle through the drive shaft 64, so that the bottom end of the material guide box 63 faces the receiving box 7. At this time, after the first conveying device 1 conveys the tablets 10 to the material guide box 63, the tablets 10 enter the receiving box 7 through the material guide box 63 for collection, thereby realizing the removal of unqualified tablets 10.

[0092] The receiving box 7 is tilted to prevent the tablets 10 from piling up at one end of the receiving box 7 close to the material guide box 63 .

[0093] The material guide box 63 includes a material guide plate and two side walls. The two side walls are arranged on both sides of the material guide plate to prevent the tablets 10 from falling from both sides of the material guide box 63.

[0094] Preferably, a photoelectric switch or other sensor can be set at the discharge end of the first conveying device 1. When the first detection member 4 or the second detection member 5 detects unqualified tablets 10, since the number of groups of qualified tablets 10 detected between the unqualified tablets 10 and the discharge end of the first conveying device 1 is certain (the tablets 10 in one material trough structure 25 are a group), when unqualified tablets 10 are detected, the photoelectric switch starts to detect the number of groups of conveyed tablets 10. When corresponding to unqualified tablets 10, the second motor 62 rotates the material guide box 63 to guide the unqualified tablets 10 into the receiving box 7.

[0095] The time at which unqualified products enter the discharge end of the first conveying device 1 can also be calculated based on the conveying speed and time of the first conveying device 1 .

[0096] The first conveying device 1 and the second conveying device 8 are both belt conveying devices made of food-grade or medical-grade materials.

[0097] See also Figure 2 As a preferred embodiment of this embodiment, both ends of the first conveying device 1 are provided with support legs 11, wherein a support block 12 is installed on one of the support legs 11, one end of the receiving box 7 is connected to the rotating shaft 71 of the other support leg 11 through a rotating shaft 71, and the other end is supported on the support block 12.

[0098] In this embodiment, each of the material removal boxes 252 contains a plurality of tablets 10 in a row. When a defective tablet 10 is detected in the row, it will be guided to the receiving box 7 through the guide structure 6. The defective tablets 10 in each row are then taken out of the receiving box 7 manually or by a robotic arm. The remaining qualified tablets 10 can then be transported to the next process for processing.

[0099] Then after removing the defective products in the receiving box 7, please refer to Figure 8 (c) in Figure 8 On the basis of (b), the second motor 62 continues to rotate counterclockwise. At this time, the material guide box 63 presses down one end of the receiving box 7 close to the second conveying device 8, so that the receiving box 7 rotates along the rotating shaft 71, so that the left end of the receiving box 7 is higher than the right end. At this time, the tablets 10 located inside the receiving box 7 slide into the second conveying device 8, and the second conveying device 8 conveys these tablets 10 to the next process, thereby facilitating the continued processing of these qualified tablets 10.

[0100] The rotating shaft 71 is fixed between the two legs 11, and the bottom of the receiving box 7 is sleeved on the rotating shaft 71, or the rotating shaft 71 is rotatably installed between the two legs 11, and the receiving box 7 is fixed on the rotating shaft 71;

[0101] One end of the receiving box 7 facing the second conveying device 8 is open, and the end of the bottom plate facing the second conveying device 8 is longer than the two side plates, so that when the tablets 10 are conveyed to the second conveying device 8, the bottom plate of the receiving box 7 can be close to the conveying surface of the second conveying device 8, so that the tablets 10 can better enter the second conveying device 8.

[0102] See also Figure 2 A guide plate 9 is provided between the discharge end of the first conveying device 1 and the guide box 63 .

[0103] By providing the guide plate 9, the tablets 10 enter the guide plate 9 from the output end of the first conveying device 1, slide from the guide plate 9 to the material guide box 63, and slide from the material guide box 63 into the second conveying device 8, thereby reducing the force acting on the tablets 10 when entering the material guide box 63 from the first conveying device 1.

[0104] The present invention also provides a tablet supply method.

[0105] A tablet feeding method, using the material conveying feeding device, comprises the following steps:

[0106] S1: The tablets 10 in the storage structure 3 fall into the feeding frame 222;

[0107] S2: The first motor 21 drives the output shaft 23 to rotate, and the output shaft 23 drives the guide ring 24 to rotate through the connecting arm 231, so that the chute structure 25 is aligned with the feed frame 222, and the tablets 10 in the feed frame 222 enter the chute structure 25;

[0108] S3: When the chute structure 25 carrying the tablet 10 rotates to the inspection port 223, the first inspection member 4 inspects the appearance of one side of the tablet 10;

[0109] S4: When the chute structure 25 carrying the tablet 10 rotates to be aligned with the discharge frame 221, the tablet 10 falls onto the first conveying device 1 by gravity, and at this time the other side of the tablet 10 faces upward. The first conveying device 1 conveys the tablet 10 to the next process. When the tablet 10 is conveyed to the second detection component 5, the second detection component 5 inspects the appearance of the other side of the tablet 10.

[0110] Among them, when the first motor 21 drives the guide ring 24 to drive the material box 252 to move to align with the feed frame 222, the tablets 10 in the feed frame 222 enter the interior of the material box 252, and the guide ring 24 continues to rotate. The convex shaft 254 at one end of the material box 252 acts on the concave surface and convex surface of the concave-convex plate 224 in sequence. When the convex shaft 254 acts on the convex surface, the convex shaft 254 pushes the material box 252 to compress the first elastic member 253. When the convex shaft 254 acts on the convex surface, the convex shaft 254 pushes the material box 252 to compress the first elastic member 253. When the convex shaft 254 is aligned with the concave surface, the elastic potential energy of the first elastic member 253 pushes the material taking box 252 to make the convex shaft 254 abut against the concave surface, so that when the convex shaft 254 passes through the concave-convex plate 224, the material taking box 252 generates a reciprocating vibration. When a tablet 10 leans against the inner wall of the material taking box 252, the reciprocating vibration allows the tablet 10 to lie flat in the material taking box 252, thereby facilitating the subsequent appearance inspection by the first detection member 4.

[0111] When the first motor 21 drives the guide ring 24 to rotate, the concave-convex surface 241 on the guide ring 24 acts on the driving arm 34, and the concave and convex surfaces on the concave-convex surface 241 act on the bottom end of the driving arm 34 in turn, and the driving arm 34 drives the V-shaped portion 32 to vibrate up and down. When the vibration is generated, the tablets 10 in the storage structure 3 can be better entered into the feeding frame 222, which greatly reduces the problem of tablet 10 being blocked.

[0112] Please refer to Figure 8 In (a), when all the tablets 10 are qualified, the first conveying device 1 slides the tablets 10 through the material guide box 63 to the second conveying device 8, and the second conveying device 8 conveys the tablets 10 to the coating process or the packaging process;

[0113] Please refer to Figure 8 In step (b), when the first detection member 4 or the second detection member 5 detects an unqualified tablet 10, when the unqualified tablet 10 enters the discharge end of the first conveying device 1, the second motor 62 drives the material guide box 63 to rotate counterclockwise by a preset angle through the drive shaft 64, so that the bottom end of the material guide box 63 faces the receiving box 7. At this time, after the first conveying device 1 conveys the tablet 10 to the material guide box 63, the tablet 10 enters the receiving box 7 through the material guide box 63 for collection, thereby achieving the removal of the unqualified tablets 10;

[0114] In this embodiment, each of the material removal boxes 252 contains a plurality of tablets 10 in a row. When a defective tablet 10 is detected in the row, it will be guided to the receiving box 7 through the guide structure 6. The defective tablets 10 in each row are then taken out of the receiving box 7 manually or by a robotic arm. The remaining qualified tablets 10 can then be transported to the next process for processing.

[0115] Then after removing the defective products in the receiving box 7, please refer to Figure 8 (c) in Figure 8 On the basis of (b), the second motor 62 continues to rotate counterclockwise. At this time, the material guide box 63 presses down one end of the receiving box 7 close to the second conveying device 8, so that the receiving box 7 rotates along the rotating shaft 71, so that the left end of the receiving box 7 is higher than the right end. At this time, the tablets 10 located inside the receiving box 7 slide into the second conveying device 8, and the second conveying device 8 conveys these tablets 10 to the next process, thereby facilitating the continued processing of these qualified tablets 10.
