[0016] The beneficial effects of the present application are as follows:

[0017] 1. Start another group of first cylinder corresponding to the material baffle, the first cylinder drives another group of material baffle moves, make the main runner and another group of secondary runner between be opened, because the ampoule bottle is placed in the full load good product area many, the resistance that the ampoule bottle enters into corresponding secondary runner is big, therefore when another group of secondary runner is opened, another group of secondary runner does not have resistance to the entry of ampoule bottle, ampoule bottle will directly enter another group of secondary runner, at this time, the ampoule bottle in the secondary runner corresponding to the full load good product area will stop moving, start corresponding first cylinder, make the material baffle seal the secondary runner and the main runner intersection, at this time, the staff can directly take the ampoule bottle placed in the good product area, replace the new ampoule carrier, therefore, compared with prior art, by setting two groups of secondary runners and adjustable material baffle, without stopping and without affecting the detection efficiency of ampoule, the carrier with ampoule placed in the good product area can be directly taken down, and the new carrier is quickly replaced, which is convenient for the staff to replace the carrier.

[0019] 3. Start the second cylinder, the second cylinder pushes the fixed plate together with the guide column and the movable plate to move, with the movable plate moving, the movable plate will extrude a group of pins, the pins will drive the corresponding plug plate to retract into the sleeve, and compress the first U-shaped spring piece, so that the plug plate cannot extend into the secondary runner, therefore, when rotating a group of gears, the pins on the reciprocating limiting plate will be extruded by the movable plate, until the pins are staggered with the movable plate, so that a group of ampoule bottles in the plurality of limiting plate area cannot be cleaned into the good product area, then drive the second cylinder again, make the movable plate move back, release the extrusion on the pin, at this time, there is no interval between the ampoule bottle between the plurality of limiting plates and the material baffle and the limiting plate, therefore, the instant moving ampoule bottle will be directly supported by the limiting plate, further reducing the risk of instant moving ampoule bottle falling over.

[0020] 4. When the defective product enters the arc chute discharge port, the defective product will squeeze the two groups of damping strips, make the damping strips turn to one side, and squeeze the second U-shaped elastic sheet.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the present application is further described below in conjunction with specific embodiments.

[0031] Embodiment one

[0032] As Figure 1 With Figure 2 The automatic sorting device for injection drug production described in the embodiment of the present application comprises a workbench 1, two groups of first rotary tables 2 are symmetrically arranged on the workbench 1, a feeding chute 3 is arranged between the two groups of first rotary tables 2, the feeding chute 3 is connected with a defective product chute 4 and a good product chute 5, the good product chute 5 is connected with a good product herringbone collection track 6, the defective product chute 4 is connected with a defective product collection mechanism 8, and the good product herringbone collection track 6 comprises: a track frame 6011, the track frame 6011 is fixedly connected with the workbench 1, a main chute 6012 arranged on the track frame 6011, the main chute 6012 is communicated with the good product chute 5, two groups of secondary chutes 6013 connected with the main chute 6012, two groups of jacks 6014 symmetrically arranged at the intersection of the main chute 6012 and the secondary chutes 6013, a material blocking plate 6015 movably inserted into the jack 6014, and a first cylinder 6016 fixedly installed on the material blocking plate 6015.

[0033] Specifically, the structure and operating principle of the first rotary disc 2 are consistent with those of the above-mentioned CN215952889U ampoule leak detection device. The two groups of secondary chutes 6013 are respectively connected to two groups of good product areas. The third material stirring strip 56 is arranged at the junction of the good product chute 5 and the main chute 6012. After the ampoules are detected by the detection components, the detected ampoules are conveyed into the feeding chute 3 through the conveying screw. With the movement of the ampoules and the continuous entry of the subsequent ampoules into the feeding chute 3, the two groups of first rotary discs 2 rotate relative to each other. When the ampoules enter the good product chute 5, they are guided by the third material stirring strip 56 and sequentially enter the main chute 6012. Under the guidance of a group of material blocking plates 6015, the ampoules enter a group of secondary chutes 6013. The good ampoules enter a group of good product areas through a group of secondary chutes 6013. When the ampoules placed in the good product area are close to full, the first cylinder 6016 corresponding to the other group of material blocking plates 6015 is started. The first cylinder 6016 moves the other group of material blocking plates 6015, so that the main chute 6012 and the other group of secondary chutes 6013 are opened. Since the good product area close to full is placed with many ampoules, the resistance of the ampoules entering the corresponding secondary chute 6013 is large. Therefore, when the other group of secondary chutes 6013 is opened, the other group of secondary chutes 6013 has no resistance to the entry of the ampoules, and the ampoules will directly enter the other group of secondary chutes 6013. At this time, the ampoules in the secondary chute 6013 corresponding to the full good product area will stop moving, and the corresponding first cylinder 6016 is started to block the intersection of the secondary chute 6013 and the main chute 6012 by the material blocking plate 6015. At this time, the staff can directly take away the ampoules placed in the good product area, and replace the new ampoule carrier plate. Therefore, compared with the prior art, by arranging two groups of secondary chutes 6013 and adjustable material blocking plates 6015, the carrier plate with ampoules placed in the good product area can be directly taken down without stopping and affecting the detection efficiency of the ampoules. The new carrier plate is quickly replaced, which is convenient for the staff to replace the carrier plate.

[0034] As shown in Figure 3 The track frame 6011 is provided with two groups of material guiding mechanisms 7. The material guiding mechanism 7 comprises a housing 701 fixedly connected to the track frame 6011, two groups of gears 702 rotatably connected in the housing 701, a synchronous belt 703 engaged with the gears 702, and a plurality of groups of limiting plates 704 equidistantly distributed on the outer circle of the synchronous belt 703. A rectangular chute 31 is formed in one side of the secondary chute 6013, and the limiting plate 704 is slidably connected to the rectangular chute 31.

[0035] Specifically, when the full load of good area needs to be replaced, the baffle 6015 corresponding to the secondary chute 6013 is opened again, and the ampoule bottles will enter the secondary chute 6013. However, there are ampoule bottles that have not entered the good area in the secondary chute 6013, so when the ampoule bottles enter the secondary chute 6013, these ampoule bottles will move instantly. Objects from prohibited to instant acceleration movement, which can easily cause the ampoule bottles to fall over. The fallen ampoule bottles will block the secondary chute 6013. Therefore, when the full load of good area needs to be replaced, the gear 702 is driven to rotate, and the synchronous belt 703 is driven to reciprocate around the two gears 702, and the synchronous belt 703 drives the plurality of limiting plates 704 to reciprocate through the rectangular chute 31. The limiting plate 704 drives the ampoule bottles to enter the good area, so that the ampoule bottles remaining between the plurality of limiting plates 704 and the good area are cleaned into the good area. Therefore, when the ampoule bottles enter the secondary chute 6013, the ampoule bottles remaining between the plurality of limiting plates 704 and the baffle 6015 are moved, and the moving ampoule bottles enter the area of the plurality of limiting plates 704. Due to the support of the limiting plate 704, the risk of instant movement of the ampoule bottles falling over is reduced.

[0036] As shown in Figures 3 to 5 The material guiding mechanism 7 further includes two groups of guide columns 705, the guide columns 705 movably insert the housing 701, a movable plate 706 fixedly installed at one end of the guide column 705, the movable plate 706 located in the rectangular chute 31, a fixed plate 707 fixedly installed at one end of the guide column 705, and a second air cylinder 708 fixedly connected to the fixed plate 707. The limiting plate 704 includes a sleeve 7041, the sleeve 7041 fixedly connected to the synchronous belt 703, a plug plate 7042 movably inserted into the sleeve 7041, a pin shaft 7043 fixedly installed on the plug plate 7042, and a first U-shaped elastic piece 7044 provided at one end of the plug plate 7042. The first U-shaped elastic piece 7044 is welded in the inner cavity of the sleeve 7041. The cylinder body of the second air cylinder 708 is fixedly connected to the housing 701. The sleeve 7041 is slidably connected to the rectangular chute 31, and the plug plate 7042 extends into the secondary chute 6013.

[0037] Specifically, during the process of rotating the set of gears 702 to clean the ampoules that stay between the sets of limiting plates 704 and the good product area into the good product area, a set of ampoules that stay between the sets of limiting plates 704 and the material blocking plate 6015 will be cleaned, so that there is a gap distance between the ampoules in this area and the limiting plates 704, so when the remaining ampoules move instantaneously towards the limiting plates 704, the ampoules may have already fallen over before they reach the nearest limiting plate 704. Therefore, before rotating the set of gears 702, the second air cylinder 708 is started, which moves the fixed plate 707 together with the guide column 705 and the movable plate 706. As the movable plate 706 moves, it will squeeze a set of pin shafts 7043, which will drive the corresponding plug plate 7042 to retract into the shell sleeve 7041, and compress the first U-shaped spring 7044, so that the plug plate 7042 cannot extend into the secondary chute 6013. Therefore, when the set of gears 702 is rotated, the pin shafts 7043 on the reciprocating limiting plates 704 will be squeezed by the movable plate 706 until the pin shafts 7043 are misaligned with the movable plate 706, so that a set of ampoules that stay in the area of the sets of limiting plates 704 cannot be cleaned into the good product area. Then the second air cylinder 708 is driven again to move the movable plate 706 back, releasing the squeeze on the pin shafts 7043. At this time, there is no gap between the ampoules that stay between the sets of limiting plates 704 and the material blocking plate 6015 and the limiting plates 704, so the ampoules that move instantaneously will be directly supported by the limiting plates 704, further reducing the risk of the ampoules that move instantaneously falling over.

[0038] As shown in Figure 6 The defective product collecting mechanism 8 includes a support table 801 fixedly connected to the workbench 1, a second turntable 802 screwed on the support table 801, two sets of pulleys 803, one set of pulleys 803 fixedly installed on the second turntable 802, the other set of pulleys 803 fixedly installed on the set of first turntables 2, and a transmission belt 804 sleeved on the two sets of pulleys 803. The support table 801 is provided with an arc-shaped chute 8011, which communicates with the defective product chute 4. A first material shifting strip 8012 is arranged at the inlet of the arc-shaped chute 8011, and a second material shifting strip 8013 is arranged at the outlet of the arc-shaped chute 8011. A plurality of sets of grooves 8021 are arranged at equal angles on the outer circle of the second turntable 802.

[0039] Specifically, the arc-shaped chute 8011 is connected with the defective product area and extends into the defective product area. When an ampoule is detected as a defective product, the staff will re-detect the defective product to determine whether the defective product is really unqualified. In the prior art, since the number of defective products detected each time is small, the defective products are mostly gathered in the defective product collection track and cannot enter the defective product area in time, so that the staff cannot collect the defective products in time. When the defective product enters the defective product chute 4, it is guided by the first stirring strip 8012 to enter the arc-shaped chute 8011. Meanwhile, the other set of pulleys 803 is driven by the first set of pulleys 803, and the other set of pulleys 803 drives the first set of pulleys 803 to rotate together with the second turntable 802. The second turntable 802 drives the defective product to slide along the arc-shaped chute 8011 through the groove 8021 until the defective product enters the discharge port of the arc-shaped chute 8011 through the guidance of the second stirring strip 8013, so that the staff can quickly and timely collect the defective products.

[0040] Embodiment two

[0041] As shown in Figure 6 the comparative embodiment one, another embodiment of the present application is that the defective product collection mechanism 8 further comprises two sets of damping mechanisms 805 which are symmetrically distributed on both sides of the discharge port of the arc-shaped chute 8011. The damping mechanism 805 comprises a damping strip 8051, a support plate 8052 screwed at the tail end of the damping strip 8051, the support plate 8052 being fixedly welded on the support table 801, a second U-shaped elastic sheet 8053 arranged on one side of the damping strip 8051, the second U-shaped elastic sheet 8053 being fixedly connected with the support table 801 on one side, and an arc-shaped surface 8054 arranged on the inner side of the damping strip 8051.

[0042] Specifically, the rotating second turntable 802 drives the defective product into the discharge port of the arc-shaped chute 8011 through the groove 8021. When the defective product enters the discharge port and is separated from the groove 8021, although the defective product loses the driving of the second turntable 802, the inertia of the defective product will continue to move, so that the defective product is thrown and flies into the defective product area, increasing the risk of the defective product being broken. Therefore, when the defective product enters the discharge port of the arc-shaped chute 8011, the defective product will press the two sets of damping strips 8051, so that the damping strips 8051 are turned to one side and press the second U-shaped elastic sheet 8053. The rebounding force of the second U-shaped elastic sheet 8053 acts on the damping strip 8051, so that the arc-shaped surface 8054 on the damping strip 8051 tightly abuts against the defective product, damping the movement of the defective product. Until the defective product is separated from the groove 8021, due to the friction of the arc-shaped surface 8054 on the defective product, the friction force offsets the inertial force of the defective product, so that the speed of the defective product entering the defective product area is greatly reduced, avoiding the defective product being broken.

[0043] The working principle is that after the ampoule is detected by the detection component, the detected ampoule is conveyed into the feeding chute 3 through the conveying screw, and with the movement of the ampoule and the continuous entry of the subsequent ampoule into the feeding chute 3, the two groups of first rotating discs 2 are rotated relative to each other, when the ampoule enters the good product chute 5, the ampoule is guided by the third shifting strip 56 and sequentially enters the main chute 6012, and under the guiding action of a group of blocking plates 6015, the ampoule enters a group of secondary chutes 6013, the good ampoule enters a group of good product areas through a group of secondary chutes 6013, when the ampoule placed in the good product area is close to full load, the first cylinder 6016 corresponding to another group of blocking plates 6015 is started, the first cylinder 6016 drives another group of blocking plates 6015 to move, so that the main chute 6012 and another group of secondary chutes 6013 are opened, and the ampoule will directly enter another group of secondary chutes 6013, at this time, the ampoule in the secondary chute 6013 corresponding to the full load good product area will stop moving, the corresponding first cylinder 6016 is started, and the blocking plate 6015 seals the intersection of the secondary chute 6013 and the main chute 6012, at this time, the staff can directly take away the ampoule placed in the good product area and replace the new ampoule carrier plate, when the good product area corresponding to the above-mentioned another group of secondary chutes 6013 needs to replace the carrier plate, the second cylinder 708 is started, the second cylinder 708 pushes the fixed plate 707 together with the guide column 705, the movable plate 706 moves, with the movement of the movable plate 706, the movable plate 706 will extrude a group of pin shafts 7043, the pin shaft 7043 drives the corresponding plug plate 7042 to retract into the shell sleeve 7041, and the plug plate 7042 cannot extend into the secondary chute 6013, a group of gears 702 are driven to rotate, with the rotation of a group of gears 702, the synchronous belt 703 is reciprocatingly transmitted around two groups of gears 702, the synchronous belt 703 will drive a plurality of groups of limiting plates 704 to reciprocate through the rectangular chute 31, the limiting plate 704 will drive the ampoule into the good product area, so that the ampoule between a plurality of groups of limiting plates 704 and the good product area is cleaned into the good product area, and then the second cylinder 708 is driven again, so that the movable plate 706 moves back, the extrusion on the pin shaft 7043 is released, and the blocking plate 6015 corresponding to the secondary chute 6013 is opened again, the instantaneously moving ampoule will be directly supported by the limiting plate 704, and the supported ampoule enters the good product area, when the defective product enters the defective product chute 4, the defective product is guided by the first shifting strip 8012 and enters the arc chute 8011, at the same time, another group of pulleys 803 is driven by a group of first rotating discs 2, another group of pulleys 803 drives a group of pulleys 803 together with the second rotating disc 802 to rotate through the transmission belt 804, the second rotating disc 802 drives the defective product to slide along the arc chute 8011 through the groove 8021, until the defective product enters the discharge port of the arc chute 8011 through the guidance of the second shifting strip 8013, and the defective product enters the defective product area through the damping of the damping strip 8051.
