As shown in fig. 1 and fig. 2, the pre-filled and sealed injector nest removing fork according to an embodiment of the present invention includes a bottom plate 1, a plurality of L-shaped racks 2, a first edge rack 3 and a second edge rack 4, wherein one ends of the L-shaped racks 2, the first edge rack 3 and the second edge rack 4 are all connected to a side surface of the bottom plate 1, and the L-shaped racks 2, the first edge rack 3 and the second edge rack 4 are all parallel to each other.
As shown in fig. 3 and 4, each L-shaped rack 2 includes a rack body 21 and a support piece 22, the cross section of the rack body 21 is rectangular, the support piece 22 is also rectangular, the support piece 22 is disposed on one side edge of the top surface 211 of the rack body 21 and perpendicular to the top surface 211 of the rack body 21, the support pieces 22 of two adjacent L-shaped racks 2 are disposed on different side edges of the top surface 211 of the rack body 21, a first gap 100 or a second gap 200 is formed between two adjacent L-shaped racks 2, a third gap 300 is formed between the first edge rack 3 and the adjacent L-shaped rack 2, and a fourth gap 400 is formed between the second edge rack 4 and the adjacent L-shaped rack 2.
The first gap 100 and the second gap 200 of the nest-releasing material fork of the pre-potting injector in the embodiment enable the needle tubes 500 to be arranged on the L-shaped rack 2 in a plurality of rows in a staggered arrangement manner, two adjacent rows of needle tubes 500 are well isolated, and in the material taking and releasing process, the needle tube flanges 520 of two adjacent rows of needle tubes 500 are not pushed and collided, so that the needle tubes 500 can be smoothly transferred. This kind of arrangement form of needle tubing 500 makes needle tubing 500 change the three-dimensional type from traditional planar type range into and arranges, owing to utilized the ascending space of direction of height to carry out the range of needle tubing 500, the utility model discloses a prefilled syringe takes off nest material fork's structure also more compact.
The first edge rack 3 in this embodiment is rectangular in cross section, and the top of the first edge rack 3 is flush with the top edge of the support piece 22 of the adjacent L-shaped rack 2. The second edge rack 4 has an L-shaped cross section, and the second edge rack 4 has a step surface 41 flush with the top surface 211 of the adjacent L-shaped rack 2. The configuration of the first and second edge racks 3 and 4 is determined according to the configuration of the L-shaped rack 2 adjacent thereto, and thus, the configuration of the first and second edge racks 3 and 4 may be the same in other embodiments. The shapes of the first edge rack 3 and the second edge rack 4 are not limited to those shown in the present embodiment, as long as they can stably support the needle tube 500.
Of course, the first edge rack 3 and the second edge rack 4 are not required, and the pre-filled syringe denesting fork of other embodiments may be devoid of the first edge rack 3 and the second edge rack 4.
Preferably, a clearance surface 10 is formed on one side of the bottom plate 1 close to the L-shaped rack 2, and the plane where the clearance surface 10 is located is lower than the top surface 211 of the rack body 21. As shown in FIG. 7, when the material-pulling sheet 610 of the material-pulling mechanism 600 pulls material, the material-pulling sheet 610 will move horizontally from the end where the L-shaped rack 2 is connected to the bottom plate 1 until the row of needle tubes 500 is completely separated from the L-shaped rack 2, the material-pulling sheet 610 and the needle tubes 500 contact with the needle tube flange 520, and in order to ensure that the material-pulling sheet 610 can perform the pulling operation well, the end of the material-pulling sheet 610 should be located below the needle tube flange 520 to ensure a sufficient contact area. When the material shifting sheet 610 shifts the needle tube 500 in the second gap 200, the row of needle tube flanges 520 is far away from the surface of the bottom plate 1, and the material shifting sheet 610 has enough space for shifting the material, but when the material shifting sheet 610 shifts the needle tube 500 in the first gap 100, the row of needle tube flanges 520 is close to the surface of the bottom plate 1, and the end of the material shifting sheet 610 is easily scraped and collided with the bottom plate 1, therefore, the clearance avoiding surface 10 is arranged on the surface of the bottom plate 1, so that more operating space can be provided for the material shifting sheet 610, the material shifting sheet 610 is prevented from being scraped and collided with the bottom plate 1, and the smooth operation of the transfer operation of the needle tube 500 is ensured.
As shown in fig. 3, preferably, an end of the L-shaped rack 2 away from the base plate 1 is provided with a first guide surface 212 and a second guide surface 213, and the first guide surface 212 and the second guide surface 213 may be arc surfaces or inclined surfaces, so that the needle tube 500 can smoothly enter the first gap 100 or the second gap 200 during the process of forking the needle tube 500 by the L-shaped rack 2.
Further, the bottom of the L-shaped rack 2 is also provided with a third guide surface 214, and the third guide surface 214 may be an arc surface or an inclined surface, so that the L-shaped rack 2 can avoid the collision between the bottom of the L-shaped rack 2 and other objects to a certain extent during the process of forking the needle tube 500, thereby causing the L-shaped rack 2 to bend.
Preferably, the side of the base plate 1 located in the first gap 100, the second gap 200, the third gap 300 and the fourth gap 400 is arc-shaped, so that the needle tube body 510 of the needle tube 500 can be more stably abutted against the side of the base plate 1, and the stability of the needle tube 500 is improved.
As shown in fig. 8, in another embodiment, the bottom plate 1 is also provided with an empty-avoiding surface 10, but one side of the empty-avoiding surface 10 is not provided with a notch, so that the processing of the nest-removing fork of the pre-filled and sealed injector of the embodiment is more time-saving. As shown in fig. 7, the bottom end of the material shifting piece 610 should be lower than the top of the needle tube flange 520 supported by the rack body 21, in order to enable the material shifting piece 610 to smoothly enter the material shifting position above the bottom plate 1, one side of the clearance surface 10 is provided with an opening, the opening enables the material shifting piece 610 to enter in a translation manner, through the return of the material fork, the material shifting piece 610 will be separated from the material discharging fork, and meanwhile, the other side of the clearance surface 10 can be opened, so that the material shifting piece 610 can conveniently exit.
As shown in fig. 9, the kick-off mechanism 600 matched with the pre-filled syringe denesting material fork shown in fig. 8 adopts a rotary kick-off piece 610, and due to the fact that the height of the kick-off piece 610 is variable, when two kick-off pieces 610 rotate to be close to a horizontal state, the pre-filled syringe denesting material fork can be directly horizontally removed.
As shown in fig. 10, in another embodiment, the bottom plate 1 is not provided with the void-avoiding surface 10, which can further reduce the processing time and cost, and the pre-filled and sealed injector nest-removing fork of this embodiment does not need to be matched with the material-shifting mechanism 600, and the pre-filled and sealed injector nest-removing fork is inclined to enable the needle tube 500 to automatically slide down under the action of gravity for removing the material.
As shown in fig. 11, in another embodiment, the void-avoiding surface 10 formed on the bottom plate 1 is an integral plane, and the void-avoiding surface 10 is not present, and the nest-removing fork of the pre-filled and sealed injector of this embodiment is suitable for not only the pull-tab type nest-removing material but also the inclined type nest-removing material.
