Workpiece straightening device

Technical Field

The utility model relates to a device of arranging one end open-ended work piece is sealed to one end for the orientation of the open end/the closed end of work piece is unified.

Background

Many workpieces, such as paper tubes, bottle bodies, cylindrical plugs, cup bodies, etc., are workpieces that are closed at one end and open at the other end. When the filling, assembling and other processing are carried out, the filling, assembling and other processing are firstly carried out, so that the opening ends/closing ends of the filling are uniformly oriented and are consistent in the same direction, and the process is called straightening.

In the prior art, for example, in the pharmaceutical industry, filling of medicine bottles or capping of medicine bottles with cylindrical plugs and the like, the sorting work is mostly finished by adopting a vibrating disk. The workpieces in the vibrating disc hopper are vibrated and ascend along the spiral track, and are screened by a series of tracks in the ascending process, so that the workpieces are in a uniform state according to the assembling or processing requirements. The defects are that a long time-consuming rail screening process is required, workpieces which do not meet the set requirements are required to be subjected to a process of returning to the rail starting point for re-screening, and the process may need to be repeated for multiple times; resulting in inefficient smoothing operations.

The utility model patent publication No. CN103256863A discloses "a direction straightening mechanism of a can binding machine". The principle of the smoothing work is as follows: screening the paper tubes in the conveying channel by using ejector pins which reciprocate towards the end parts of the paper tubes, wherein if the ejector pins push against the closed ends of the paper tubes, the paper tubes are pushed out of the conveying channel; if the ejector pin is pushed to the opening end of the paper tube, the ejector pin is inserted into the opening end and cannot push the paper tube, the paper tube is left in the conveying channel, and after the ejector pin is retracted and reset, the paper tube continues to enter the next working procedure along the conveying channel. As can be seen from the above, the workpieces that do not meet the set requirements in the mechanism may also undergo a re-screening process that returns to the starting point, and this process may need to be repeated many times. Similar to the vibration disk, the mechanism also has the problem of low straightening work efficiency.

The first intervention piece 5 is driven by the cylinder to reciprocate towards the workpiece, and if the workpiece 3 is clamped when entering the channel B2 from the channel A1, the workpiece 3 is triggered to be released when the first intervention piece 5 moves downwards. A second intervention 6 reciprocating towards the workpiece 3 is provided below the blocking element 4. The second intervention 6, by means of reciprocating movement towards the workpiece 3, touches the workpiece 3 to avoid possible jamming of the workpiece 3 on the transverse plate of the B channel 2. To avoid interfering with the drop path of the workpiece 3, the second intervention 6 should be retracted after actuation. The two intervention pieces can act once when each workpiece passes through, and can also act timely according to the feedback of the monitoring element.
