The cap supplying mechanism 300 supplies caps by using a scheme of the prior publication, such as a scheme of a plastic cap supplying device of publication No. CN 104276533A. The conveying mechanism 100 is provided with a rack crossing the conveying mechanism 100, the cap supply mechanism 300 is fixed on the rack, the cap supply mechanism 300 comprises at least one cap supply passage 310, in this embodiment, two cap supply passages 310 are provided, and the two cap supply passages 310 are different in size so as to supply two different specifications of bottle caps, and when the notch bottles with different sizes are replaced, the bottle caps with proper sizes can be selected for the notch bottles with two specifications by adjusting the track of the docking mechanism 400. The two cap supply passages 310 are spaced apart in a vertical plane perpendicular to the conveying mechanism 100 and are arranged side by side in a plane parallel to the conveying mechanism 100. By adopting the cap supply mechanism 300 with the structure or the similar structure, the bottle cap is obliquely arranged when being positioned at a position to be taken, and the cap taking column 420 is used for propping against the inner side wall of the bottle cap to take the bottle cap away from the cap supply mechanism 300, so that the motion track of the cap taking column 420 can not be reciprocating motion, but needs to be annular track unidirectional motion.

The present embodiment does not specifically limit the specific structure of the translation driving mechanism 410 and the circular track of the cap removing column 420, and includes but is not limited to the following cases:

example 1: the translation driving mechanism 410 comprises a rotation driving motor and a cantilever, the rotation driving motor and the cap taking column 420 are respectively located at two ends of the cantilever, and the rotation driving motor drives the cantilever to rotate by taking the length of the cantilever as a radius, so that the motion track of the cap taking column 420 is in a circular ring shape, and the cap taking column 420 rotates clockwise or anticlockwise to carry out the connection operation of the bottle cap according to the positions of the cap screwing mechanism 200, the cap supplying mechanism 300 and the connection mechanism 400.

Example 2: as shown in fig. 5, the translation driving mechanism 410 includes a transverse moving mechanism and a longitudinal moving mechanism, the longitudinal moving mechanism is slidably disposed on the transverse moving mechanism, the cap taking column 420 is slidably disposed on the longitudinal moving mechanism, and the movement tracks of the cap taking column 420 are controlled by the transverse moving mechanism and the longitudinal moving mechanism, the transverse moving mechanism and the longitudinal moving mechanism can operate synchronously and can operate separately, in order to simplify the track setting difficulty, the transverse moving mechanism and the longitudinal moving mechanism in this embodiment operate separately, the movement tracks are shown in fig. 4, the arrow in the figure is the one-way movement direction of the cap taking column 420, the two frames in the figure represent the station where the cap screwing mechanism 200 is located and the station where the cap supplying mechanism 300 is located, respectively, wherein the station where the cap supplying mechanism 300 is located at the upstream.

Preferably, the transverse moving mechanism mainly drives the cap taking column 420 to move along the operation direction of the conveying mechanism 100 in a horizontal plane, the transverse moving mechanism comprises transverse guide rails 411, linear motors 412 and transverse sliders 413, the number of the transverse guide rails 411 is two, the length direction of the transverse guide rails is parallel to the operation direction of the conveying mechanism 100, the linear motors 412 are also arranged in parallel to the transverse guide rails 411, the transverse sliders 413 are arranged on the transverse guide rails 411 in a penetrating mode, the transverse guide rails 411 are used for limiting when the transverse sliders 413 move, the transverse sliders 413 are enabled to move along the transverse direction, the linear motors 412 are connected with the transverse sliders 413, the transverse sliders 413 are driven to move through the linear motors 412, and the longitudinal moving mechanism is fixed on the transverse sliders 413. Because the cap removing column 420 needs to be accurately stopped at the station where the cap screwing mechanism 200 is located when the cap removing column moves transversely, the linear motor 412 can well meet the requirement on the operation precision of the cap removing column 420.

Preferably, the longitudinal moving mechanism mainly drives the cap removing column 420 to move in a direction perpendicular to the running direction of the conveying mechanism 100 in a horizontal plane, the longitudinal moving mechanism comprises a longitudinal guide rail 414, two linear air cylinders 415 and two longitudinal sliding blocks 416, the two longitudinal guide rails 414 are provided, the longitudinal sliding blocks 416 are slidably arranged on the longitudinal guide rail 414, balance during sliding of the longitudinal sliding blocks 416 can be ensured through the two longitudinal guide rails 414, the linear air cylinders 415 are fixed at the ends of the longitudinal guide rails 414, the longitudinal sliding blocks 416 are pushed to slide along the longitudinal guide rails 414 through the linear air cylinders 415, and the cap removing column 420 is fixedly hung on the longitudinal sliding blocks 416.

In order to fix the cap taking columns 420 conveniently, a cap taking plate 430 may be disposed on the longitudinal sliding block 416, and the cap taking columns 420 are fixed on the cap taking plate 430, so that the relative positions of the two cap taking columns 420 may be fixed to correspond to the two sets of screw cap assemblies, the size of the longitudinal sliding block 416 may be reduced, and the longitudinal sliding block 416 is prevented from being too large.

As shown in fig. 6, in addition to the above-mentioned embodiment, since the feeding mechanism 100 is frequently opened and closed to reduce the feeding efficiency due to the necessity of keeping the notch bottle in a stationary state with respect to the capping mechanism 200 at the time of capping, the automatic capping apparatus further includes a main stopper mechanism 500, and the main stopper mechanism 500 is provided in order to block the notch bottle while the feeding mechanism 100 is normally operated at the time of capping.

Because the conveying mechanism 100 vibrates during conveying the notch bottle, the position of the notch bottle can deviate to a certain extent on the conveying mechanism 100, and the bottle mouth can not be aligned with the capping mechanism 200 easily, therefore, on the basis of the main limiting mechanism 500, the automatic capping device is further provided with the auxiliary limiting mechanism 600, the main limiting mechanism 500 and the auxiliary limiting mechanism 600 are respectively positioned at the left side and the right side of the running direction of the conveying mechanism 100, namely the main limiting mechanism 500 and the auxiliary limiting mechanism 600 are respectively arranged at the two sides of the conveying mechanism 100 along the longitudinal direction, the auxiliary limiting mechanism 600 is arranged to be matched with the main limiting mechanism 500, and the notch bottle waiting for capping is clamped from the two sides so as to correct the position of the notch bottle, and the capping mechanism 200 can accurately screw the bottle cap on the notch bottle.

as shown in fig. 8, the docking mechanism 400 is located at the initial position, the cap taking column 420 is located in the upstream direction of the cap supplying mechanism 300, that is, the starting point of the segment of the moving track a of the cap taking column 420, at this time, the linear motor 412 of the transverse moving mechanism is started to drive the transverse slider 413 to move in the parallel direction of the movement of the conveying mechanism 100, the cap taking column 420 passes through the cap supplying mechanism 300, the cap is arranged on the cap supplying mechanism 300 in an inclined manner, the opening of the cap faces the cap taking column 420, when the cap taking column 420 passes through, the cap taking column 420 contacts with the inner side of the opening of the cap to take the cap from the cap supplying mechanism 300, at this time, the cap is covered on the cap taking column 420, then the linear motor 412 will continue to drive the cap taking column 420 to move towards the station of the capping mechanism 200, when the cap taking column 420 reaches the station of the capping mechanism 200, that is, the cap taking column 420 is located below the capping head 240, the vertical driving motor 210 of the capping mechanism 200 drives the capping head 240 to move down, the capping head 240 clamps the bottle cap from the capping column 420, then the vertical driving motor 210 drives the capping head 240 to move upwards, so that the bottle cap is separated from the capping column in the vertical direction, the capping column is driven by the linear motor 412 to move forwards for a certain distance, after the capping column is separated from the station of the capping mechanism 200, the linear motor 412 stops operating, the linear cylinder 415 pushes the capping column 420 to move longitudinally, i.e. to enter the b segment of the operation track, the longitudinal movement distance is mainly required to avoid the capping mechanism 300 in the longitudinal direction, then the linear cylinder 415 stops operating, the linear motor 412 is started to drive the capping column 420 to move along the c segment of the operation track, the capping column 420 is moved to the upstream direction of the capping mechanism 300 in the transverse direction, then the linear motor 412 stops operating, the linear cylinder 415 is pneumatic, the capping column 420 moves along the d segment of the operation track, and returning to the starting point of the segment of the running track a, and starting the next reciprocating running.

In the above process, when the capping head 240 of the capping mechanism 200 grabs the bottle cap or a little before, the main limiting mechanism 500 and the sub-present device are simultaneously activated, the limiting cylinder 512 pushes the limiting plate 520 to move, the inserting portion 521 of the limiting plate 520 stops in front of the notch bottle running direction to prevent the notch bottle from moving forward, the side stop portion 522 of the limiting plate 520 abuts against the side wall of the notch bottle, the sub-driving mechanism 620 on the other side also drives the sub-baffle 610 to run towards the notch bottle to make the sub-baffle 610 abut against the other side wall of the notch bottle, and the side stop portion 522 and the sub-baffle 610 of the limiting plate 520 clamp the notch bottle from the left and right sides of the notch bottle running direction to correct the position of the notch bottle.
