Detailed Description

The invention is further described with reference to the following figures and examples.

Referring to fig. 1, a capsule weight detecting and selecting mechanism comprises a vibrating plate 5 and a capsule transferring mechanism 6.

The vibratory pan 5 is provided with a chute 51 for allowing the capsules to slide down in line in the longitudinal direction. The lower end of the chute is provided with a straight section 52 which can only accommodate one capsule. The bottom of the straight section 52 is provided with a bracket avoiding through hole 53. The connecting part of the straight section and the chute is provided with a barrier rod avoiding through hole 54.

The capsule transfer mechanism 6 includes a carriage 61 and a carriage lifting mechanism 62 that drives the carriage to lift. The carriage lift mechanism 62 is a two-stroke cylinder. The bracket is provided with a bracket 63 which is arranged in the supporting and avoiding through hole in a penetrating way, a barrier rod 64 which is arranged in the barrier rod avoiding channel in a penetrating way and a stop rod 65 which is positioned at one end of the straight section far away from the sliding groove. The upper end of the blocking rod is higher than the upper end of the arresting rod. In the initial state, the double-stroke cylinder extends for a stroke, so that the blocking rod blocks the capsule on the straight section from falling down and the blocking rod does not interfere the capsule in the sliding chute to slide down. A weight sensor for detecting the weight of the capsule is arranged in the bracket. The sliding groove is also provided with a blower 7 for blowing off the capsule jacked up by the bracket.

The method for detecting and selecting the weight of the capsule by the capsule weight detecting and selecting mechanism comprises the following steps: firstly, pouring capsules to be selected into a vibration disc, queuing the capsules in a sliding groove, sliding the capsules out of the sliding groove onto a straight section, and blocking the capsules by a blocking rod; secondly, the bracket lifting mechanism drives the bracket to ascend, namely the double-stroke cylinder extends out of a second stroke, so that the blocking rod is blocked between the straight section and the sliding groove to prevent the capsule in the sliding groove from sliding to the straight section and the bracket from lifting the capsule to be weighed by the weight sensor and align with an air outlet of the blower; thirdly, if the weight detection sensor detects that the weight of the capsule does not meet the requirement, starting a blower to blow off the capsule in the bracket; if the weight detection sensor detects that the weight of the capsule meets the requirement, the bracket descends to the point that the stop lever loses the blocking effect on the capsule on the straight section, namely the double-stroke cylinder retracts by two strokes, the capsule falls off from the straight section under the pushing effect of the subsequent capsule, and when the distance of the capsule sliding out of the straight section is more than half of the length of the capsule in the process that the capsule slides off the straight section, the bracket lifting mechanism ascends, namely the double-stroke cylinder ascends by one stroke and resets, so that the ejector rod resets to block one end of the straight section, which is far away from the sliding groove, and the capsule which is not weighed on the straight section is prevented from sliding off the straight section.
