Compared with the original syringe and vial or ampoule combined vaccine injection Injection of medicinal liquid preparations with prefilled syringes is faster and safer. Since the body of the prefilled syringe is generally made of borosilicate glass for long-term contact with the medicinal liquid, it has excellent water and acid resistance. During the long-term contact with the medicinal liquid, it will not cause changes in the pH value, and there will be no precipitation or glass. Chip shedding and other advantages. After the pre-filled syringes go through the pharmaceutical process such as aseptic tray filling and screening, light inspection, screw rod labeling and other pharmaceutical processes by the front equipment, the product participates in the final blister packaging or box packaging. Syringes may be collected in buffer boxes in a disordered manner before being packaged, and disordered prefilled syringes need to be packaged in blister packs or cartons again. In the face of this packaging process, how to arrange the prefilled syringes in a disordered state in the buffer frame in an orderly manner, so as to adapt to the subsequent blister packaging or box packaging, has become a reality. sexual difficulties. Among the existing solutions, there is an arrangement method in which the prefilled syringes are placed manually, resulting in very low production efficiency, or the method of sorting by rotating the discs may easily cause damage to the external labels of the prefilled syringes.

Embodiments of the present invention

As shown in FIG. 1 , the syringe lifting feeding device includes an organic base 1 on which a feeding table 2 and a material lifting mechanism 3 are installed. The feeding table 2 is located on one side of the material lifting mechanism 3 . Feeding platform 2 can be vibratory feeding platform 2 (also belongs to protection scope of the present invention), can allow material to move forward by vibration, but cost is higher; In order to reduce cost, the table top of feeding platform 2 can be inclined downwards (all of the present invention The "downward slope" refers to the downward slope toward the direction in which the syringe 6 is to move and the "tilt" is relative to the horizontal plane, the same below), as shown in Figure 2, the syringe placed on the feeding table 2 6 will move to the position of the material lifting mechanism 3 due to the inclined surface of the feeding table 2.

After the syringe 6 on the feeding table 2 moves to the material lifting mechanism 3, the material lifting mechanism 3 lifts the syringe step by step, and when lifted to the highest point, an orderly row is formed. As shown in Figure 3, the material lifting mechanism 3 includes a support 30, a first lifting ladder 31, a second lifting ladder 32 and a lifting power source 33, and the first lifting ladder 31 includes a plurality of first lifting steps arranged in steps. 310 (as shown in FIG. 8, a plurality of first lifting steps 310 are connected to the first ladder frame 317 to form a whole to constitute the first lifting ladder 31), the upper end of each first lifting step 310 is inclined downward, and the first lifting step 310 is inclined downward. A lifting ladder 31 is slidably arranged on the support 3 through the first slide rail 315; the second lifting ladder 32 includes a plurality of second lifting steps 320 arranged in steps (a plurality of second lifting steps 320 are connected to the second ladder frame above, forming a whole to form the second lifting ladder 32), the upper end of each second lifting step 320 is inclined downward, the second lifting ladder 32 is slid on the support 30 through the second slide rail 325, and the first lifting ladder The first lifting step 310 of 31 and the second lifting step 310 of the second lifting ladder 32 are arranged at intervals and are close to each other, and both the first lifting ladder 31 and the second lifting ladder 32 are connected with the lifting power source 33 and move in opposite directions (the second The first lifting ladder 31 and the second lifting ladder 32 can be driven by one lifting power source 33 to move in the opposite direction, or can be driven by two lifting power sources 33 to move in the opposite direction).

The working principle of the material lifting mechanism 3 is as follows: as shown in Figure 3, during work, the lifting power source 33 drives the first lifting ladder 31 and the second lifting ladder 32 to move in opposite directions (if one moves upward, the other moves downward, And vice versa), the syringe 6 on the feeding platform 2 first falls onto the upper end face of the first lifting step 310 at the bottom of the first lifting ladder 31 (because this first lifting step 310 is closest to the feeding platform 2), and then the first The lifting ladder 31 moves up, and the second lifting ladder 32 moves down. Since the upper end of the first lifting step 310 is inclined downward, the syringe 6 moves from the upper end of the first lifting step 310 at the bottom of the first lifting step 31 to the second lifting step 320 at the bottom of the second lifting step 32 On the upper end face, since the first lifting step 310 of the first lifting ladder 31 and the second lifting step 320 of the second lifting ladder 32 are arranged at intervals, the syringe on the second lifting step 320 transitions to the first lifting step of the upper level. 310, passing upwards in this way, the syringe 6 is lifted to the highest point step by step. During the step-by-step lifting process, only the syringes placed laterally on the upper end face of the lifting step are retained, and the skewed syringes will fall off. Fall down, when syringe reaches highest point like this, just form a neat row of syringes, as shown in Figure 4, injector 6 just falls to material conveying mechanism 5 afterwards, is delivered to next station by material conveying mechanism 5 syringe.

As mentioned above, the first lifting ladder 31 and the second lifting ladder 32 move in opposite directions, and the simultaneous movement of the two can improve the feeding efficiency. Of course, under the condition of not considering the feeding efficiency, as long as the first lifting ladder 31 moves up and down, and the second lifting ladder 32 is fixed, the feeding can also be realized, but the efficiency will be reduced.

Due to structural problems, it is difficult for the material conveying mechanism 5 to be directly installed on the discharge end side of the material lifting mechanism 3 (interference will occur). One side of the feed end is provided with a slideway plate 4, as shown in Figure 4, the slideway plate 4 is inclined downward, and the material conveying mechanism 5 is arranged on the discharge end side of the slideway plate 4, as shown in Figure 5, the material The conveying mechanism 5 includes two left and right conveying belts 50 and a feeding power source 51 for driving the conveying belts 50 to move. A distance is formed between the left and right conveying belts 50 for the cylinder 60 of the syringe 6 to pass through. When the syringe 6 is lifted to the highest point, the syringe 6 falls on the slideway plate 4 due to the downward slope of the upper end of the lift step (no matter it is the first lift step 310 or the second lift step 320). Tilt downward, and the syringe 6 falls onto the material conveying mechanism 5. The material conveying mechanism 5 has two conveyor belts 50 on the left and right. Since the center of gravity of the syringe 6 is at the center of the cylinder 60, as shown in Figure 9, the syringe 6 The cylinder 60 of the cylinder 60 just passes between the two conveyor belts 50, and the finger grip flange 61 of the syringe 6 is just hung on the two conveyor belts 50, so that the syringe 6 stands up, driven by the feeding power source 51, The left and right conveyor belts 50 just drive the syringe 6 to be transported to the next station.

In order to prevent the position of the syringe 6 from being deflected during the sliding process on the slideway plate 4 , the slideway plate 4 is distributed with several guide grooves for the finger gripping flange 61 of the syringe 6 to enter. When the syringe 6 came to the slideway plate 4, the finger gripping flange 61 of the syringe 6 entered the guide groove, and since the guide groove played a limiting role on the finger gripping flange 61 of the syringe 6, the syringe could be guided like this. 6 enters on the material conveying mechanism 5 without deflection.

In order to prevent the syringe 6 from falling out from the side during the lifting process, the present invention is equipped with two baffle plates 10 on the machine base 1, the first lifting ladder 31 and the second lifting ladder of the feeding table 2 and the material lifting mechanism 3 32 are located between the two baffles 10. Due to the blocking of the baffle plate 10, the syringe 6 will not fall from the side.

Both the first lifting ladder 31 and the second lifting ladder 32 can be installed vertically, as shown in Figure 6, only the upper end surface of the first lifting step 310 of the first lifting ladder 31 will be inclined downward, and the second lifting ladder The upper end surface of the second lifting step 320 of 32 will also be made to be inclined downward, so that the processing of the lifting step will be cumbersome, and the syringe 6 is easy to drop on the upper end surface of the lifting step. In order to solve this problem, as shown in Figure 2, the support 30 of the present invention has a mounting slope 302, as shown in Figure 4, a first sliding seat 316 and a second sliding seat 326 are installed on the mounting slope 302, the first sliding rail 315 slides on the first sliding seat 316, and the second sliding rail 325 slides on the second sliding seat 326 (of course, the positions of the sliding seat and the sliding rail can be reversed, that is, the sliding rail is installed on the installation slope of the support 30 302, and the sliding seat is installed on the lifting group, the two methods are equivalent, and both belong to the protection scope of the present invention). Since the first lifting ladder 31 and the second lifting ladder 32 are all installed on the mounting slope 302 of the support 30, the first lifting ladder 31 and the second lifting ladder 32 naturally form an inclined structure (as shown in Fig. 2 and Fig. 7 shown), even if the first lifting step 310 of the first lifting ladder 31 and the second lifting step 320 of the second lifting ladder 32 are made into a common plate-shaped structure, the upper end surface of the lifting step will also be inclined downward. The processing and manufacturing are simpler (as long as the lifting step is made into a common plate shape), and the syringe is less likely to fall due to the overall tilt.

In order to drive the first lifting ladder 31 to move up and down, as shown in FIG. Wheel 313, the first transmission wheel 313 has a first eccentric column, the first eccentric column is hinged with one end of the first connecting rod 312, the other end of the first connecting rod 312 is hinged with the first connecting arm 311, and the first connecting arm 311 It is connected with the first lifting ladder 31. During work, the lifting power source 33 drives the first synchronous wheel 314 to rotate, the first synchronous wheel 314 drives the first transmission wheel 313 to rotate, and the first transmission wheel 313 drives the first connecting rod 312 and the first connecting arm 311 through the first eccentric column They move up and down together, and finally the first connecting arm 311 drives the first lifting ladder 31 to move up and down. Of course, there are many ways to drive the first lifting ladder 31 to move up and down, and here only provides a specific implementation.

Similarly, in order to drive the second lifting ladder 32 to move up and down, the present invention is equipped with a second synchronous wheel 324 connected to the lifting power source 33 on the support 30, and a second transmission wheel 323 is installed on the second synchronous wheel 324. There is a second eccentric column on the second transmission wheel 323, the second eccentric column is hinged with one end of the second connecting rod 322, the other end of the second connecting rod 322 is hinged with the second connecting arm 321, and the second connecting arm 321 is connected with the second connecting arm 321. Lift ladder 32 is connected. During work, the lifting power source 33 drives the second synchronous wheel 324 to rotate, the second synchronous wheel 324 drives the second transmission wheel 323 to rotate, and the second transmission wheel 323 drives the second connecting rod 322 and the second connecting arm 321 through the second eccentric column move up and down together, and finally the second connecting arm 321 drives the second lifting ladder 32 to move up and down. Of course, there are many ways to drive the second lifting ladder 32 to move up and down, and here only provides a specific implementation.

The first lifting ladder 31 and the second lifting ladder 32 can be driven by one lifting power source 33, and can also be driven by two lifting power sources 33. In order to reduce costs and improve the synchronization between the two, it is best to use the former, For this reason, the present invention is installed with the 3rd synchronous wheel 300 on the support 30, the 3rd synchronous wheel 300, the 2nd synchronous wheel 324 and the 1st synchronous wheel 314 are wound with synchronous belt 301, the 3rd synchronous wheel 300 and lifting power Source 33 transmission connection. The lifting power source 33 drives the third synchronous wheel 300 to rotate, and the second synchronous wheel 324 can be driven to rotate synchronously with the first synchronous wheel 314 through the synchronous belt 301, so that the first lifting ladder 31 and the second lifting ladder 32 can realize reverse synchronously. direction movement, because only one lifting power source 33 (being a motor) is used, the cost is lower.
