[0012] The included angle between the bottle taking slide and the bottle delivering slide is 133°.

[0015] Beneficial effects: 1. The angle between the bottle feeding slide and the lower bottle picking slide of the present invention is 133°, so that when the medicine bottle feeding track is symmetrically designed, the two groups of bottle feeding slides are parallel, and the two groups of lower bottle picking slides are at an angle of 94°, which is convenient for using one feeding mechanism to feed the two groups of medicine bottle feeding tracks at the same time, simplifying the feeding structure, and at the same time, the medicine bottle conveying mechanism can take bottles from the inside of the bottle picking slides on both sides by rotating 133° forward and 133° reverse during the boxing process. The bottle picking process is convenient, and the bottle feeding speed of the medicine bottle feeding track remains unchanged.

At the same time, the bottle picking claw plate on one side does not hinder the feeding of the medicine bottle feeding track on the other side when taking materials, and the bottling efficiency is higher.

[0016] 2. A partition column is provided at the lower part of the bottle picking claw plate of the present invention. The partition column is made of plastic material and is conical. The partition column can separate the medicine bottles squeezed together during the downward process, and avoid damage to the medicine bottles or collision with each other to cause the medicine bottles to break during the bottle picking process while keeping the speed unchanged, thereby ensuring the safety of the bottle picking process. At the same time, the separation by the partition column during the bottle picking process can also make the picked medicine bottles arranged more evenly and neatly, so that the medicine bottles are arranged more regularly after boxing and there is a certain interval between the medicine bottles, thereby ensuring the safety of the bottle picking process and achieving a better boxing effect.

[0017] 3. The medicine bottle spacing adjustment block of the present invention is controlled by the adjustment block driving cylinder to move a certain distance. When the medicine bottles just enter the bottle picking slide, the medicine bottles are squeezed against each other and arranged too closely, making it difficult to grab them. The medicine bottle limiting cylinder controls the lower medicine bottle limiting column to move downward and press on the upper part of the medicine bottle, so that the pressed medicine bottles cannot move, thereby blocking the medicine bottles that have not entered the bottle picking slide, preventing the medicine bottles that have not entered the bottle picking slide from squeezing the medicine bottles inside the bottle picking slide and causing damage. Afterwards, the adjustment block drives the cylinder to control the medicine bottle spacing adjustment block to move away from the lower limit block connecting platform for a certain distance. While moving, the spacing adjustment suction hole absorbs the medicine bottles at the end and moves synchronously, thereby reserving enough distance for the grabbing work of the bottle picking claw plate. At the same time, the partition column can separate the squeezed bottles together during the downward process, and separate the tightly arranged medicine bottles, to ensure that the high-speed grabbing operation is balanced, stable and efficient.

[0038] Further, the medicine bottle moves from the bottle feeding slide 58 to the lower bottle picking slide 68. After the bottle picking slide 68 is completely filled, the medicine bottle limiting cylinder 21 is started to lower the lower limiting block connecting platform 22, so that the lower medicine bottle limiting column 57 is pressed against the corresponding medicine bottle, with the pressed medicine bottle as the boundary, and the medicine bottle inside the boundary is the medicine bottle to be grabbed. Then the adjustment block driving cylinder 63 drives the medicine bottle spacing adjustment block 36 to retreat. The medicine bottle spacing adjustment block 36 sucks the end of the medicine bottle to be grabbed through the spacing adjustment suction hole 64 and takes it away for a certain distance, so as to reserve enough space for the grabbing of the medicine bottle. At the same time, the medicine box conveying mechanism 2 moves the empty medicine box to the bottle placing station, and then the lifting servo motor 35 drives The lifting drive screw 37 rotates to make the screw mother shaft 39 move downward, so that the bottle picking claw bearing platform 15 moves downward as a whole, so that the bottle picking claw plate 51 at the bottle picking position has the bottle picking suction hole 54 to suck up the medicine bottle to complete the bottle picking. Synchronously, the bottle picking suction hole 54 of the bottle picking claw plate 51 at the bottle placing position stops sucking air to make the medicine bottle fall into the medicine box. At this time, one bottle picking and bottle placing is completed. Then, the servo motor 25 is rotated to start driving the bottle picking claw bearing platform 15 to rotate 133°, so that the bottle picking claw plate 51 that has completed the bottle picking moves to the bottle placing position, and the bottle picking claw plate 51 that has completed the bottle placing moves to the bottle picking position corresponding to another group of medicine bottle feeding tracks 4. This device continuously repeats the above steps to continuously perform the boxing operation.

[0039] It should be noted that the angle between the bottle feeding slide 58 and the lower bottle picking slide 68 is 133°. When the medicine bottle feeding track 4 is designed symmetrically, the two groups of bottle feeding slides 58 are parallel, and the two groups of lower bottle picking slides 68 are at an angle of 94°, which makes it convenient to use one feeding mechanism to feed the two groups of medicine bottle feeding tracks 4 at the same time, simplifying the feeding structure, and at the same time, the medicine bottle conveying mechanism 3 can take bottles from the bottle picking slides 68 on both sides by rotating 133° forward and 133° reverse during the boxing process. The bottle picking process is convenient, and the bottle feeding speed of the medicine bottle feeding track 4 remains unchanged. The bottling speed is more than twice that of the feeding of a single group of medicine bottle feeding track 4. At the same time, the bottle picking claw plate 51 on one side does not hinder the feeding of the medicine bottle feeding track 4 on the other side when taking materials, and the bottling efficiency is higher.

[0040] It should also be noted that the medicine bottle spacing adjustment block 36 is controlled by the adjustment block driving cylinder 63 to move a certain distance. When the medicine bottle just enters the bottle picking slide 68, the medicine bottles are squeezed against each other and arranged too closely, making it difficult to grab. When grabbing at high speed, the vial is prone to wear or tiny cracks. The medicine bottle limiting cylinder 21 controls the lower medicine bottle limiting column 57 to move downward and press on the upper part of the medicine bottle, so that the pressed medicine bottle cannot move, thereby blocking the medicine bottle that has not entered the bottle picking slide 68, preventing the medicine bottle that has not entered the bottle picking slide 68 from being caught. The medicine bottles inside the bottle picking slide 68 are squeezed by the bottle-picking cylinder 63, and then the medicine bottle spacing adjustment block 36 is controlled to be away from the lower limit block connecting platform 22 by the adjustment block. While moving, the spacing adjustment suction hole 64 sucks the medicine bottles at the end to move synchronously, thereby reserving enough distance for the grabbing work of the bottle picking claw plate 51, and at the same time separating the closely arranged medicine bottles, ensuring that the high-speed grabbing operation is balanced, stable and efficient, ensuring the accuracy of the box loading action, and the bottles sucked by the high-speed operation can be accurately loaded into the medicine box to prevent damage to the medicine box due to misalignment or uneven force.

[0041] It should also be noted that a partition column 53 is provided at the lower part of the bottle-picking claw plate 51. The partition column 53 is made of plastic material. The partition column 53 can separate the squeezed medicine bottles during the downward process to prevent the syringe bottles from being worn or having tiny cracks, and to avoid damage to the medicine bottles or collisions with each other during the bottle-picking process, thereby ensuring the safety of the bottle-picking process. At the same time, the separation by the partition column 53 during the bottle-picking process can also make the picked-up medicine bottles arranged more evenly and neatly, so that the arrangement of the medicine bottles after boxing is more regular and there is a certain interval between the medicine bottles. In the case of high-speed boxing, the safety of the medicine bottles is guaranteed, the force of the high-speed grasping operation is balanced and stable, and the boxing effect is better.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be regarded as within the scope of protection of the present invention.
