DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. As long as the effect of the utility model can be achieved, various changes can be made to the implementation solutions.

[0035] The components in the case are connected in sequence by the person skilled in the art, and the specific connection and operation sequence should refer to the following working principle. The detailed connection means is the known technology in the art, and the following mainly introduces the working principle and process.

[0036] Reference Figures 1-5 A flat blister packaging machine is described in the embodiment.

[0037] The flat blister packaging machine in the embodiment comprises a packing machine 1 and a detection camera 10 for detecting whether the tablet blister plate is damaged or the tablets are not filled. The packing machine 1 is provided with a conveying belt 2, and the tablet blister plate is conveyed in a direction on the conveying belt 2.

[0038] In the embodiment, the packing machine 1 is provided with a buckle box 3 buckled on the conveying belt 2. The buckle box 3 is provided with openings on both sides for the conveying belt 2 to pass through. The buckle box 3 is fixed with a side box 6 close to the opening on the side of the entering direction of the conveying belt 2. The detection camera 10 is fixed on the bottom of the side box 6 and suspended above the conveying belt 2. The tablet blister plate on the conveying belt 2 is detected by the detection camera 10 when passing through the side box 6.

[0039] Further, as Figure 2As shown, the top of the buckle box 3 is fixed with a first pneumatic telescopic rod 4, the output end of the first pneumatic telescopic rod 4 penetrates the top wall of the buckle box 3 and extends into the interior of the buckle box 3, and the output end of the first pneumatic telescopic rod 4 is fixed with a pressing needle assembly. When the detection camera 10 detects a defective blister card (for example, a damaged or unfilled blister card), the first pneumatic telescopic rod 4 is extended to work when the part of the blister card moves to a position below the first pneumatic telescopic rod 4, the pressing needle assembly is pierced into the blister card, the first pneumatic telescopic rod 4 is retracted to pull the defective blister card upward, and the defective blister card is separated from the normally conveyed blister cards. By using the piercing type of up and down movement, the defective blister card can be separated from the remaining good blister cards upward, and the influence on the good blister cards during the separation process is small, and the good blister cards will not be offset.

[0040] In a preferred embodiment, as shown in Figure 3 The pressing needle assembly includes a main arm plate 12, a beam arm plate 13, a plurality of second pneumatic telescopic rods 14, and a needle 15. The main arm plate 12 is fixed on the output end of the first pneumatic telescopic rod 4, and the beam arm plate 13 is fixed on the bottom of the main arm plate 12. The plurality of second pneumatic telescopic rods 14 are fixed on the beam arm plate 13 at equal intervals, and the output end of the second pneumatic telescopic rod 14 penetrates the beam arm plate 13. The needle 15 is fixed on the output end of the second pneumatic telescopic rod 14. The first pneumatic telescopic rod 4 drives the main arm plate 12, the beam arm plate 13, and the components assembled on the beam arm plate 13 to descend as a whole, so that the needle 15 is suspended above the defective blister card. At this time, the single or multiple second pneumatic telescopic rods 14 drive the needle 15 to descend and insert into the defective blister card, so that the defective blister card is clamped on the needle 15. Then, the second pneumatic telescopic rod 14 rises to carry the defective blister card away from the conveying belt 2.

[0041] In the present embodiment, as shown in Figure 4 The needle 15 includes a needle rod 151 fixed on the output end of the first pneumatic telescopic rod 4, a needle head 154 fixed on the bottom of the needle rod 151, a knurled raised ring 152 provided on the outer wall of the bottom of the needle rod 151, and an annular groove 153 formed between two adjacent knurled raised rings 152. When the needle 15 is driven by the second pneumatic telescopic rod 14 to descend, the needle head 154 partially pierces into the defective blister card. After continuous piercing, the defective blister card is clamped on the knurled raised ring 152 and the annular groove 153, preventing the defective blister card from falling off the needle rod 151 when the first pneumatic telescopic rod 4 rises.

[0042] In the present embodiment, as shown in Figure 2 and Figure 5As shown, the part of the conveying belt 2 located in the buckle box 3 is provided with a roller set 16, and the conveying belt 2 is overlapped on the roller set 16 to form a recess 17, and a bearing is arranged inside the recess 17 and arranged in the cross-sectional direction of the conveying belt 2. When installed, the roller set 16 and the bearing are located below the insertion pin 15, and the two are correspondingly arranged to ensure that the insertion pin 15 is located on the bearing when pressed down, preventing the insertion pin 15 from directly piercing the conveying belt 2 and causing damage.

[0043] Specifically as Figure 5 As shown, the roller set 16 includes two first rollers arranged oppositely and a second roller located below the two first rollers, and the conveying belt 2 is overlapped on the upper surface of the first roller and the lower surface of the second roller. The two first rollers and the second roller form the recess 17 when the conveying belt is running.

[0044] The bearing includes a base 18, and a strip-shaped groove 20 is opened on the base 18, and a rubber pad strip 21 is fixed in the strip-shaped groove 20. After the insertion pin 15 is lowered and penetrates the defective blister card, the penetrating part of the insertion pin 15 extends onto the rubber pad strip 21 in the strip-shaped groove 20 to protect the needle 154 and prevent it from bending.

[0045] The two sides of the base 18 are fixed with side plates 19, and the top surfaces of the base 18 and the side plates 19 are flush with the conveying belt 2 to ensure that the blister card conveyed on the conveying belt 2 can move along the side plates 19 to the base 18, and then moved out by the side plate 19 on the other side and back to the conveying belt 2.

[0046] The top of the buckle box 3 is also fixed with an electric telescopic rod 5, the output end of the electric telescopic rod 5 penetrates through the top wall surface of the buckle box 3 and is fixed with a material scraping baffle 11, and the material scraping baffle 11 is provided with a through hole through which the pressing pin assembly can pass. When the first pneumatic telescopic rod 4 rises and falls, the electric telescopic rod 5 rises and falls synchronously. When the second pneumatic telescopic rod 14 descends, the insertion pin 15 extends below the material scraping baffle 11, and when the second pneumatic telescopic rod 14 rises, the insertion pin 15 retracts above the material scraping baffle 11. In the process of retracting the insertion pin 15, the defective blister card clamped on the surface of the insertion pin 15 is limited by the material scraping baffle 11 and separated from the insertion pin 15.

[0047] Further, the inside of the side box body 6 is provided with a defective product conveying belt 7, and the side box body 6 is provided with an output opening in the output direction of the defective product conveying belt 7. The top of the opening of the buckle box 3 close to the outflow direction of the conveying belt 2 is provided with a flap 9, and the top of the flap 9 is provided with a driving motor 8; wherein the driving motor 8 can drive the flap 9 to swing, so that the bottom of the flap 9 is suspended above the defective product conveying belt 7.

[0048] During implementation, the drive motor 8 drives the folding plate 9 to rotate, causing the folding plate 9 to be tilted and its bottom suspended above the defective product conveyor belt 7. When the defective product blister pack is restricted by the scraper baffle 11 and disengaged from the insert pin 15, the defective product blister pack falls onto the folding plate 9 and slides down the inclined surface of the folding plate 9 onto the defective product conveyor belt 7. The operation of the defective product conveyor belt 7 causes the defective product blister pack to fall out of the output opening to the outside.

[0049] like Figure 2 As shown, the folding plate 9 has a first flip angle and a second flip angle. When the folding plate 9 is at the first flip angle, it is in contact with the inner wall of the buckle box 3. When the folding plate 9 is at the second flip angle, it is suspended above the defective product conveyor belt 7. When the folding plate 9 is at the first flip angle, it facilitates the up and down movement of the pressure needle assembly. When the folding plate 9 is at the second flip angle, the folding plate 9 is inclined, allowing the defective product blister packs to fall onto the defective product conveyor belt 7.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
