Detailed Description
The following examples are illustrative of the invention and are not intended to limit the scope of the invention.
Unless otherwise indicated, all technical means employed in the specification are those known in the art.
Example 1
The liquid medicament packaging system comprises a measuring cup cover arranging device and a capping device, wherein the measuring cup cover arranging device is connected with the capping device through a cup cover conveying belt 5;
in this embodiment, the measuring cup cover arranging device includes a measuring cup cover bin 1, a lifting belt 2, and a measuring cup cover groove 3, where the measuring cup cover groove is located above the measuring cup cover bin, and the measuring cup cover bin is connected with the measuring cup cover groove through the lifting belt; the measuring cup cover groove is cylindrical, a cover hole is formed in the side wall of the measuring cup cover groove, and the cover hole is connected with the measuring cup cover conveying belt; the measuring cup cover conveying belt is bent back downwards from the cover outlet hole, so that a measuring cup cover conveyed on the measuring cup cover conveying belt is turned from an opening upwards to an opening downwards; a circular plate 301 is arranged in the measuring cup cover groove, the edge of the circular plate is provided with holes, the size of the holes is matched with the measuring cup cover 6, and the circular plate is connected to the bottom surface of the measuring cup cover groove through a rotating shaft.
A cover pulling part 8 is arranged on the side wall of the measuring cup cover groove, and comprises a pulling arm 801, the front end of which is positioned at the opening of the circular plate; the shifting arm is connected with a driving motor and a manual rotating handle.
The bottom surface of the measuring cup cover groove forms an included angle of 15-50 degrees with the horizontal plane, and the cover outlet hole is positioned on the side wall at the high position; a radial straight rod 304 is arranged on a circular plate in the measuring cup cover groove, and the length of the straight rod is smaller than the diameter of the circular plate. Through operation tests, the rotating device can stably operate when the bottom surface of the cup cover measuring groove forms an included angle of less than 45 degrees with the horizontal plane.
In operation, it was found that even with the lid pulling member 8 and the bottom surface of the measuring cup lid slot at an angle of 30 degrees to the horizontal, a small amount of the cup lid was still stacked and rotated into the lid outlet 305.
Example 2
Experiments show that the bottom surface of the measuring cup cover groove forms an included angle of 30 degrees with the horizontal plane, and a small amount of cup covers are overlapped and rotated to the cover outlet hole 305. However, if the bottom surface of the measuring cup cover groove is set to be more than 45 degrees with the horizontal plane, the torque born by the rotating mechanism is too large, the operation is not facilitated, and the measuring cup is easy to drop when the angle is too large, so that the speed of the measuring cup cover cannot be matched with the conveying speed of the bottle body. Considering the small mass of the measuring cup lids, attempts have been made to blow open the stacked measuring cup lids with an air flow.
A blowing nozzle 7 is arranged outside the cover outlet hole, and is connected with a compressed air pipeline; the air outlet of the blowing nozzle is rectangular or approximately rectangular, the air outlet direction faces the inside of the measuring cup cover groove in the radial direction, and the air outlet is arranged above the height of one measuring cup cover on the conveyor belt and is lower than the superposed height of the two measuring cup covers. The blowing nozzle is connected with a compressed air pipeline, and the air pressure in the compressed air pipeline is used for controlling the blowing nozzle to give out air: the tests were carried out under different air pressures, suitably at an air pressure of 4 to 5bar.
Because the lid is frustoconical (see fig. 5), it is preferable that the blowing air flow is in the upper portion of the lid, and that the stacked lids can be blown off with a smaller air flow.
Other settings were the same as in example 1.
