As shown in fig. 1 to 21, a syringe boxing production line includes:

a first conveying mechanism 11 for conveying the syringe 2 that has been packaged; one side of the syringe 2 after the packaging is completed is shown in fig. 2 in the embodiment, that is, the lower side is the side where the packaging cavity is located, and the other side is the side where the plastic packaging paper is located.

In order to ensure that the packaged syringe 2 cannot shift during transmission, the first conveying belt 111 on the first conveying mechanism 11 is composed of a plurality of belt bodies 112 with certain elasticity, a support for supporting the belt bodies 112 is arranged below the belt bodies 112, and the spacing distance between the adjacent belt bodies 112 is equal to the transverse width of the packaging cavity, so that when the cavity of the packaged syringe 2 faces downwards, the packaging cavity is just clamped between the belt bodies 112, and the syringe 2 cannot shift.

The first conveying mechanism 11 may be a part of a packaging machine, or may be a structure separately provided as long as the function of conveying the packaged syringe 2 can be realized.

The transfer mechanism 3 is configured to transfer the syringes 2 on the first conveying mechanism 11 to the second conveying mechanism 12 or/and the third conveying mechanism 13, and the syringes 2 may be transferred to the second conveying mechanism 12 and the third conveying mechanism 13 in a plurality of times by using one transfer mechanism 3, or the syringes 2 may be transferred to the second conveying mechanism 12 and the third conveying mechanism 13 by using two transfer mechanisms 3. In this embodiment, the syringes 2 on the first transport device 11 are transferred to the second transport device 12 and the third transport device 13, respectively, for one transfer.

Specifically, the transfer mechanism 3 includes a support 31 disposed across the crossing portion of the first conveying mechanism 11 and the second conveying mechanism 12, a cross rail 32 disposed on the support 31, a plurality of first sucking and releasing units 33 and second sucking and releasing units 34 capable of translating along the cross rail 32, a separating linkage 331 disposed between the adjacent first sucking and releasing units 33, the separating linkage 331 can also simultaneously realize linkage separation between the adjacent second sucking and releasing units 34, a first power unit 332 for driving the first sucking and releasing units 33 to ascend and descend, and a second power unit 342 for driving the second sucking and releasing units 34 to ascend and descend, the first sucking and releasing units 33 and the second sucking and releasing units 34 are disposed in parallel, and are disposed in parallel back and forth along the axial direction of the first conveying mechanism 11.

In this embodiment, the number of the first sucking and discharging units 33 and the number of the second sucking and discharging units 34 are three, the number of the syringes 2 is 6, and each group includes 5 syringes 2.

The working process comprises the following procedures,

c1, the first sucking and releasing unit 33 and the second sucking and releasing unit 34 suck the whole cut 6 groups of syringes and then move upwards, as shown in fig. 6;

c2, in the process of moving upwards, the adjacent first sucking and releasing units 33 are transversely opened by the separating linkage 331, so that the 3 groups of syringes sucked by the first sucking and releasing units 33 are respectively separated, and the adjacent second sucking and releasing units 34 are also transversely opened by the separating linkage 331 at the same time, so that the 3 groups of syringes sucked by the second sucking and releasing units 34 are respectively separated, as shown in fig. 7;

c3, the transfer mechanism 3 is translated, so that the first suction and discharge unit 33 is positioned right above the second conveying mechanism 12, and the second suction and discharge unit 34 is positioned right above the third conveying mechanism 13, as shown in fig. 4;

c4, the first sucking and discharging unit 33 moves downwards to place 3 groups of the second part injectors 22 on the second conveying mechanism 12 under the driving of the first power unit 332, and the second sucking and discharging unit 34 moves downwards to place 3 groups of the first part injectors 212 on the third conveying mechanism 13 under the driving of the second power unit 342;

c5, lifting and resetting the first sucking and releasing units 33, simultaneously, translating, closing and resetting the adjacent first sucking and releasing units 33 in the lifting process, and translating to the position right above the first conveying mechanism 11 to realize translation resetting after the first sucking and releasing units 33 are lifted to the target position; the second suction and discharge units 34 are lifted and reset, meanwhile, the adjacent second suction and discharge units 34 are translated, gathered and reset in the lifting process, and after the second suction and discharge units are lifted to a target position, the second suction and discharge units are translated to the position right above the first conveying mechanism 11 to realize translation reset. In this embodiment, the first sucking and discharging unit 33 and the second sucking and discharging unit 34 perform the translation operation synchronously.

A second conveying mechanism 12 for conveying a second partial syringe 22, in which the packaging impressions are placed face down.

The third conveying mechanism 13 is arranged in parallel with the second conveying mechanism 12 up and down, the tail end of the third conveying mechanism is provided with a turnover mechanism 4, when the transfer mechanism 3 transfers the syringe 2 on the first conveying mechanism 11 to the third conveying mechanism 13, the packaging cavity of the syringe 2 is placed with the face facing downwards, the turnover mechanism 4 is used for turning the syringe 2 with the packaging cavity facing downwards to be placed with the face facing upwards, and the part of the syringe 2 is defined as a first part of the syringe 21.

Specifically, as shown in fig. 3, the turnover mechanism 4 includes a rotating shaft 41, an accommodating cavity 42 capable of turning over along with the rotating shaft 41, and a hook 43 disposed at one side of the accommodating cavity 42, where the accommodating cavity 42 may turn over synchronously along with the rotating shaft 41 or may turn over asynchronously; the containing cavity 42 has at least a first opening 421, in an initial state, the first opening 421 faces to the tail end of the third conveying mechanism 13, and when the syringe 2 is driven by the third conveying mechanism 13 to enter the containing cavity 42 from the first opening 421, the rotating shaft 41 is driven to rotate, so as to drive the containing cavity 42 containing the syringe 2 to turn over, so that the cavity of the syringe 2 faces upwards.

In order to translate the syringe 2 inside the containing cavity 42 away from the containing cavity 42, when the containing cavity 42 is turned over by 180 °, the hook 43 is driven to translate, so as to draw the syringe 2 out of the containing cavity 42 to the fourth conveying mechanism 14; in order to ensure the matching between the hook 43 and the accommodating cavity 42, the accommodating cavity 42 has an opening structure on both sides in addition to the first opening 421, in other words, the accommodating cavity 42 is U-shaped, the hook 43 is disposed between the adjacent accommodating cavities 42, one side of each accommodating cavity 42 can be integrally disposed, the side is a side which is attached to the third conveying mechanism 13 in the initial state, and the other side of each accommodating cavity 42 must be intermittently disposed, so that after the accommodating cavities 42 are turned over, the hook 43 can extend into the gap between the adjacent accommodating cavities 42 to pull out the syringe 2 to the fourth conveying mechanism 14.

The fourth conveying mechanism 14, which is arranged in parallel with the third conveying mechanism 13, may be arranged on the same horizontal plane, or may be arranged on a horizontal plane slightly higher than the third conveying mechanism 13, and is configured to translate the first part of the syringes 21 after being turned over to be close to the loading mechanism 5, as shown in fig. 3.

In order to save the length occupied space of the whole syringe 2 boxing production line, the first conveying mechanism 11 and the second conveying mechanism 12 can be arranged side by side and in a staggered mode, namely the tail part of the first conveying mechanism 11 and the head part of the second conveying mechanism 12 are located on the same horizontal plane, and the length space is saved. Of course, the two parts can be arranged side by side, but the head and the tail parts are not staggered. At this time, a waste collecting box or a product detecting device is arranged at the tail end of the first conveying mechanism 11 in a space, so that when some packaged syringes 2 are marked as defective products, the syringes can be directly output by the first conveying mechanism 11 and fall to the waste collecting box, a waste receiving device with a complex structure is not required to be arranged particularly, and the packaged syringes 2 can be checked and monitored by the product detecting device.

A loading mechanism 5 for alternately placing the first part syringes 21 and the second part syringes 22 in the packing box 23.

The third conveying mechanism 13 is positioned above the second conveying mechanism 12, and the axial length of the third conveying mechanism is smaller than that of the second conveying mechanism 12; to facilitate the action of the charging mechanism 5, the starting end of the third conveyor 13 is located downstream of the starting end of the second conveyor 12, and the trailing end of the third conveyor 13 is located upstream of the trailing end of the second conveyor 12.

The fourth conveying mechanism 14 is arranged right above the second conveying mechanism 12 on the same level with the third conveying mechanism 13. Therefore, the fourth conveying mechanism 14 can translate between the length difference between the tail ends of the second conveying mechanism 12 and the third conveying mechanism 13, when the charging mechanism 5 needs to obtain the second part of the injector 22 from the second conveying mechanism 12, the fourth conveying mechanism 14 translates the overturning mechanism 4 close to the third conveying mechanism 13 to give way to the charging mechanism 5, and when the charging mechanism 5 needs to obtain the first part of the injector 212, the fourth conveying mechanism 14 drives the injector 2 in the overturning mechanism 4 to translate and close to the charging mechanism 5.

Specifically, the fourth conveying mechanism 14 includes a fourth conveying track, a loading platform capable of translating along the fourth conveying track, and buffer members located on the upper surface of the loading platform, and a cavity portion for clamping the packaged syringe 2 is arranged between adjacent buffer members.

The charging mechanism 5 specifically comprises a transmission assembly 51, a movable shaft 52 which can rotate and lift under the drive of the transmission assembly 51, and an adsorption assembly 53 connected to the end part of the movable shaft 52, wherein the adsorption assembly 53 can move downwards and is adsorbed on the corresponding part of the buffer part by using negative pressure, so that effective adsorption is realized, and the injector 2 is ensured to be smoothly adsorbed on the adsorption assembly 53.

The transmission assembly 51 realizes the movement of the adsorption assembly 53 between the position of the fourth conveying mechanism 14 or the second conveying mechanism 12 and the position of the packing box 23. Which is not described in detail in the prior art.

and when in grabbing, the first part injector 21 with the cavity facing upwards and the second part injector 22 with the cavity facing downwards are grabbed alternately, so that the first part injector 21 and the second part injector 22 are stacked alternately, and the placing space is saved.

The alternate stacking can be transverse dislocation, axial dislocation in the length direction, or both transverse dislocation and axial dislocation, and is determined according to the shape of the injector to achieve the most reasonable placement mode.

similarly, the first part injector 21 with the upward-facing cavity and the second part injector 22 with the downward-facing cavity are alternately grabbed during grabbing, so that the first part injector 21 and the second part injector 22 are alternately stacked, and the placing space is saved.
