Operation principle: referring to fig. 8, during feeding, a self-tapping screw is slid into the blanking hole 32 along the slide tube 3, and during implementation, two modes are defined:
mode one: the first cylinder 3 drives the blanking block 32 to move leftwards, so that a blanking hole 33 close to the material taking opening 28 is aligned with the material sliding pipe 3, so that a self-tapping screw sleeve sliding out of the material sliding pipe 3 directly enters the blanking hole 33, and then the first cylinder 3 drives the blanking block 33 to move rightwards again, so that the blanking hole 33 is aligned with the through hole, and the self-tapping screw sleeve enters the lower bin 30 along the through hole;
mode two: in the first mode, when one self-tapping screw sleeve enters the blanking hole 33 positioned in the right direction, then one self-tapping screw sleeve enters the transit bin 35 in the movable ball plate 34, in the initial state, the movable ball plate 34 is positioned at the initial position, the upper end of the transit bin 35 is communicated with and aligned with the sliding pipe 3, then the first air cylinder 3 drives the blanking block 32 to the right side again, so that the transit bin 35 is aligned with and not communicated with the through hole, and therefore, the second motor 25 is required to be started to drive the movable ball plate 35 to rotate 180 degrees, the transit bin 35 drives the self-tapping screw sleeve to rotate 180 degrees, and the self-tapping screw sleeve in the transit bin 35 enters the lower bin 30 along the through hole;
for the first mode and the second mode, the following points are needed to be described:
first point: in the first mode, when the blanking block 32 moves, wherein when the blanking holes 33 on the right side are aligned with the through holes, both blanking holes 33 cannot be aligned with the blanking pipes 3, and the positions in fig. 8 are illustrated, wherein the tail end positions of the blanking pipes 3 are located at the middle positions of the transfer bin 35 and the blanking holes 33, the movable ball plate 34 needs to be driven by the second motor 25 to turn 180 degrees, so that the transfer bin 35 is not communicated with the blanking pipes 3, and after one self-tapping screw sleeve slides into the blanking hole 33, the first cylinder 4 drives the blanking block 32 to move to the right side until the self-tapping screw sleeve in the blanking hole 33 slides into the lower bin 30, and the rest self-tapping screw sleeves in the blanking pipes 3 cannot enter the transfer bin 35, so that the purpose is that: subdividing each self-tapping screw sleeve, so that the whole feeding process is in a stable state, after the tapping screw sleeve enters the lower bin 30, the second cylinder 4 is started successively, the self-tapping screw sleeve entering the lower bin 30 along the through hole is pushed to the position of the material taking opening 28 by the pushing block 31, the self-tapping screw sleeve is taken out by a grabbing structure on self-tapping screw sleeve equipment, and the grabbing structure is not limited specifically;
second point: for the structure of the upper bin 29 and the lower bin 30, the two are mutually independent, the upper bin 29 comprises two actions of feeding and overturning the self-tapping screw sleeve, the lower bin 30 only comprises a pushing action, the self-tapping screw sleeve is conveniently taken out by the grabbing structure, and the action processes between the two are mutually noninterfere, and are specifically expressed as follows: when the blanking block 32 feeds or centers on the self-tapping screw sleeve, the pushing block 31 in the lower bin 30 can independently execute pushing action, so that in the feeding process, the pushing action is independently executed by the overturning action or feeding action in the upper bin 29, so that the whole feeding process can be continuously executed, and the time of 'interrupting feeding' in the whole feeding process can not be caused by the centering action;
third point: in combination with the first point and the second point, the blanking block 32 is a switching structure in the whole alignment action, and is used for sequentially feeding a plurality of self-tapping screw sleeves in the sliding material pipe 3 into the lower bin 30, and arranging the movable ball plate 34 for matching with the alignment action, in the process of pushing the self-tapping screw sleeves, an additional positioning and grabbing structure is not required in the whole alignment action except for the pushing block 31, so that the self-tapping screw sleeves in the sliding material pipe 3 are fed into the lower bin 30, and the moving position of the blanking block 32 is synchronously controlled by only adopting a single first cylinder 4, so that the purpose of accurate feeding can be realized by using the single first cylinder 4;
fourth point: what needs to be further explained is: the horizontal movement of the blanking block 32 and the up-and-down movement of the mounting seat 21 are in a cooperative state, and the two movement nodes are mutually matched, which is specifically expressed as follows: in the downward moving process of the mounting seat 21, one self-tapping screw sleeve is extruded into the slide material pipe 3, so that the blanking block 32 needs to perform a single moving action, the self-tapping screw sleeve at the lowest end inside the slide material pipe 3 is automatically discharged, the enough self-tapping screw sleeve is ensured to be contained inside the slide material pipe 3, the problem that feeding is interrupted in the whole equipment operation process is avoided, the problem that the horizontal moving action of the blanking block 32 and the upward and downward moving action of the mounting seat 21 are synchronously performed can be understood to be a moving state, namely, in the action that the mounting seat 21 starts to move downwards, the blanking block 32 needs to move synchronously, the collision interference of the two actions is avoided, and in the same way, the blanking block 32 synchronously performs a resetting action and returns to the initial position when the mounting seat 21 moves upwards for resetting.
