Technical Field

[0001] The present invention relates to the technical field of sorting, and in particular to a hard capsule sorting device. Background Art

[0002] Hard capsules are a common drug packaging that can mask the unpleasant bitterness and odor of drugs, making them easier to swallow. After the hard capsules are made, they need to be sorted to avoid insufficient drug content inside the hard capsules, which in turn affects the quality and efficacy of the drugs.

This patent uses photoelectric sensors for inductive sorting. Although this can effectively detect whether the hard capsule is full of material, most hard capsules do not fill the entire capsule. Therefore, during the movement and pouring of the capsule, the material in the hard capsule may accumulate at one end. Therefore, only using photoelectric sensors for induction cannot effectively sort hard capsules of different specifications and those that are not filled.

[0004] In view of the above problems, a hard capsule sorting device is now developed which can effectively sort hard capsules of different specifications and those that are not filled. Summary of the invention

[0010] In addition, it is particularly preferred that it also includes a dust removal mechanism, which includes a movable brush, a support rod and a return spring. The inner side of the upper part of the shell is symmetrically slidingly connected to two front and rear support rods. A movable brush is connected between the lower sides of two adjacent support rods. The movable brushes are respectively in contact with adjacent sorting wheels, and a return spring is connected between the support rods and the shell.

[0011] In addition, it is particularly preferred that a shaking mechanism is also included, which includes a cam, a shaking plate, a sliding arm and a vibration spring, the front side of the static elimination rod close to the inner side and the rear side of the static elimination rod close to the outer side are connected to the cam, the inner walls on the left and right sides of the ash hopper are slidably connected to the shaking plates, the rear side of the shaking plate close to the outer side and the front side of the shaking plate close to the inner side are connected to the sliding arms, the sliding arms are slidably connected to adjacent ash hoppers, and the sliding arms are respectively connected to the adjacent ash hoppers with vibration springs.

[0013] In addition, it is particularly preferred that ash outlet holes are provided on both the left and right sides of the ash hopper.

[0014] Beneficial effects: 1. The present invention can adjust the wind force of the fan according to the weight of the hard capsules that need to be sorted. The fan will blow out the hard capsules that do not meet the standards in the hard capsules backwards and then fall into the waste material recovery box. The hard capsules that meet the standards will not be blown away.

At the same time, a common motor can be started to drive the static elimination rod to rotate, which can also stir the hard capsules, thereby increasing the efficiency of removing static electricity from the hard capsules.

[0017] 4. Under the action of the return spring, the movable brush can always be in contact with the sorting wheel, so that the movable brush can brush away the dust remaining on the sorting wheel, thereby preventing the dust on the sorting wheel from contaminating the hard capsules.

[0018] 5. When the static electricity eliminating rod of the present invention rotates, it will also drive the cam to rotate. The rotation of the cam will intermittently move the sliding arm, thereby driving the shaking plate to move. Under the action of the vibration spring, the shaking plate and the sliding arm move back and forth, thereby achieving a shaking effect, thereby preventing the hard capsules from staying in the ash hopper and not falling during sorting.

[0019] 6. In the present invention, when the hard capsule rotates to the lower side with the sorting wheel, the push-out block will move downward due to gravity, the return spring will be stretched, and the hard capsule will be pushed down, so that the hard capsule can be prevented from being stuck in the placement groove on the sorting wheel and not falling.

DETAILED DESCRIPTION

[0032] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope and application scope of the present invention are not limited.

[0033] Example 1

[0034] A hard capsule sorting device, such as Figure 1-Figure 4 As shown, it includes a shell 1, a waste material recovery box 2, a sorting mechanism 3 and a separating mechanism 4. Two left and right waste material recovery boxes 2 are installed on the inner side of the rear part of the shell 1. The upper part of the shell 1 is provided with a sorting mechanism 3, and the sorting mechanism 3 is used to sort the hard capsules. A separating mechanism 4 is provided between the sorting mechanism 3 and the shell 1, and the separating mechanism 4 is used to separate unqualified hard capsules.

[0035] like Figure 2 , Figure 3 and Figure 4As shown, the sorting mechanism 3 includes a sorting wheel 31, a linkage shaft 32, a servo motor 33 and a fan 34. The left and right servo motors 33 are fixedly connected to the inner side of the front portion of the shell 1 by bolts. The output shafts of the servo motors 33 are connected to the linkage shafts 32, and the linkage shafts 32 are connected to the sorting wheels 31. Fifteen placement slots are evenly arranged on the outer circumference of the sorting wheel 31. The left and right fans 34 are connected to the inner side of the middle portion of the shell 1, and the fans 34 are respectively located in front of adjacent sorting wheels 31.

[0036] like Figure 2 and Figure 4 As shown, the partition mechanism 4 includes a push block 41 and a support spring 42. The inner side of the middle part of the shell 1 is slidably connected to the left and right push blocks 41. The upper sides of the push blocks 41 are set higher in the front and lower in the back. A support spring 42 is connected between the push block 41 and the shell 1.

[0037] When the hard capsules need to be sorted, the servo motor 33 is started, and the servo motor 33 drives the linkage shaft 32 to rotate, and then drives the sorting wheel 31 to rotate, and then the hard capsules can be put in from the upper part of the shell 1, so that the hard capsules enter the placement slots on the sorting wheel 31 one by one, and the fan 34 can be started at the same time. People can adjust the wind force of the fan 34 according to the weight of the hard capsules to be sorted. When the material in the hard capsules does not meet the standard, the weight of the hard capsules is relatively light. In this way, when the hard capsules move to the rear side of the fan 34 with the placement slots on the sorting wheel 31, the fan 34 will blow out the hard capsules whose materials do not meet the standard backwards, and then fall into the residual waste material recycling box 2, and the hard capsules whose materials meet the standard will not be blown away. In this way, sorting can be carried out quickly and effectively, and hard capsules of different specifications and weights can be sorted. For sorting; secondly, some hard capsules that do not meet the standards may not be completely blown off when they are blown backwards. At this time, the rotation of the sorting wheel 31 will drive the hard capsules that do not meet the standards to continue to rotate, so that the front side of the hard capsules that do not meet the standards will contact the push block 41. Because the upper side of the push block 41 is set high at the front and low at the back, the hard capsules that do not meet the standards will slide backwards along the upper surface of the push block 41, thereby ensuring that the hard capsules that do not meet the standards are sorted and fall into the waste material recycling box 2, and the hard capsules that meet the standards will not be blown backwards, so that the front side of the hard capsules will not contact the upper surface of the push block 41, and the hard capsules that meet the standards will squeeze the push block 41 and move inward, the support spring 42 is compressed, and then continue to rotate and move smoothly with the sorting wheel 31. When the hard capsules are completely sorted, the servo motor 33 and the fan 34 can be turned off.

[0038] Example 2

[0039] On the basis of Example 1, Figure 2 , Figure 5 and Figure 6As shown, it also includes a static electricity removal mechanism 5, which includes an ash hopper 51, a motor bracket 52, a common motor 53 and a static electricity removal rod 54. The ash hoppers 51 are welded to the upper sides of the left and right parts of the shell 1, and the left and right sides of the ash hopper 51 are opened with ash outlet holes, the front side of the ash hopper 51 is welded with a motor bracket 52 on the inner side, the upper side of the motor bracket 52 is fixed with a common motor 53 by bolts, the middle part of the ash hopper 51 is rotatably connected with two left and right static electricity removal rods 54, the output shafts of the common motor 53 are respectively connected to the adjacent static electricity removal rods 54, and the front sides of the static electricity removal rods 54 on the same ash hopper 51 are connected with transmission parts.

[0040] When the hard capsules need to be sorted, the hard capsules to be sorted can be placed in the ash hopper 51, and then the static elimination rod 54 can be started, and the static elimination rod 54 will blow out charged air masses, thereby eliminating static electricity and dust for the hard capsules to be sorted, and the dust will be discharged through the ash outlet hole of the ash hopper 51. At the same time, the ordinary motor 53 can be started, and the ordinary motor 53 will drive the static elimination rod 54 near the inside to rotate. The rotation of the static elimination rod 54 near the inside will drive the static elimination rod 54 near the outside to rotate through the transmission part, so that the hard capsules can be stirred, thereby increasing the efficiency of removing static electricity from the hard capsules. When the hard capsules are sorted, the ordinary motor 53 and the static elimination rod 54 are turned off.

[0041] like Figure 2 , Figure 7 and Figure 8 As shown, it also includes a dust removal mechanism 6, which includes a movable plate brush 61, a support rod 62 and a return spring 63. The upper inner side of the shell 1 is symmetrically connected to the front and rear support rods 62 in a sliding manner. A movable plate brush 61 is welded between the lower sides of two adjacent support rods 62. The movable plate brush 61 is in contact with the adjacent sorting wheels 31 respectively, and a return spring 63 is connected between the support rods 62 and the shell 1.

[0042] Under the action of the return spring 63, the movable brush 61 can always be in contact with the sorting wheel 31, so that the movable brush 61 can brush away the dust remaining on the sorting wheel 31, thereby preventing the dust on the sorting wheel 31 from contaminating the hard capsules.

[0043] like Figure 2 , Fig. 9 and Fig.10As shown, it also includes a shaking mechanism 7, which includes a cam 71, a shaking plate 72, a sliding arm 73 and a vibration spring 74. The front side of the static elimination rod 54 close to the inner side and the rear side of the static elimination rod 54 close to the outer side are both connected with the cam 71, and the inner walls on the left and right sides of the ash hopper 51 are both slidably connected with the shaking plate 72, and the rear side of the shaking plate 72 close to the outer side and the front side of the shaking plate 72 close to the inner side are both welded with sliding arms 73, and the sliding arms 73 are slidably connected to adjacent ash hoppers 51, and vibration springs 74 are respectively connected between the sliding arms 73 and adjacent ash hoppers 51.

[0044] When the static electricity eliminating rod 54 rotates, it will also drive the cam 71 to rotate. The rotation of the cam 71 will intermittently move the sliding arm 73, thereby driving the shaking plate 72 to move. Under the action of the vibration spring 74, the shaking plate 72 and the sliding arm 73 move back and forth, thereby achieving a shaking effect, thereby preventing the hard capsules from staying in the ash hopper 51 during sorting and not falling.

[0045] like Figure 2 and Fig.11 As shown, it also includes an ejection mechanism 8, which includes an ejection block 81 and a return spring 82. Fifteen ejection blocks 81 are slidably connected to the inner side of the sorting wheel 31 in a circumferentially uniform arrangement. The ejection blocks 81 correspond to the placement slots on the sorting wheel 31 respectively, and a return spring 82 is connected between the ejection blocks 81 and the sorting wheel 31.

[0046] When the hard capsule rotates to the lower side with the sorting wheel 31, the push-out block 81 will move downward due to gravity, and the return spring 82 will be stretched, thereby pushing the hard capsule down, so as to prevent the hard capsule from being stuck in the placement slot on the sorting wheel 31 and not falling. When the sorting wheel 31 continues to rotate, the push-out block 81 rotates and moves upward, and the return spring 82 retracts and drives the push-out block 81 to move inward and reset, thereby not preventing the hard capsule from falling into the placement slot on the sorting wheel 31.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
