Description

A quick positioning device for split packing box

technical field

The invention relates to a quick positioning device for a split packaging box.

Background technique

Among the existing cigarette packaging boxes, the split-type packaging box has been widely used in high-end cigarettes, gifts, cosmetics, etc. due to its convenience in taking and placing. When shopping for items, there is a problem that the packaging box needs to be accurately and quickly positioned. The existing traditional positioning methods are as follows: 1. Manually find the position of the packaging box first, and then use the machine to fill it. This method has low efficiency and high labor intensity. 2. Automatic positioning. The existing positioning methods use sensors to sense the outer contour of the packaging box, and the positioning is achieved by combining electromechanical technology. However, due to manufacturing deviations in the inner and outer contours, the center may shift. The positioning accuracy of this method is limited, generally ± 2mm, and when the positioning response time is long and the working frequency is high (over 40 times/min), the positioning is unstable, and due to the combination of electromechanical technology, the system is complicated and maintenance and adjustment are troublesome.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies of the prior art and provide a fast positioning device for split packaging boxes with high positioning accuracy, strict synchronization with cigarette pack filling, short response time, simple maintenance and high reliability.

The purpose of the present invention is achieved through the following technical solutions:

A quick positioning device for a split packaging box, including a straightening cam and a straightening device, the straightening device includes a straightening device seat, a straightening device main column, a straightening device secondary guide post, a straightening main fork, a straightening device The positive and auxiliary forks, the upper positive plate and the lower positive plate, the setter seat is installed in the loading mechanism, the rotation of the settling cam is linked with the up and down movement of the filling mechanism, and the setter seat is vertically provided with Two linear bearings, the main column of the straightener and the secondary guide column of the straightener are installed in the two linear bearings, and the upper side of the main column of the straightener and the secondary guide column of the straightener are fixedly connected by the guide column plate , the guide column plate is installed on the straightening cam through a connecting device, and the main column of the straightening device is installed with a straightening main fork and a straightening auxiliary fork through bearings on the underside of the straightening device seat in turn, and the straightening A return spring is installed between the main fork and the straightening auxiliary fork, the middle part of the straightening main fork and the straightening auxiliary fork is connected with the main column of the straightening device, and the two ends of the main fork are connected by the main column of the straightening device The upper positive plate is installed symmetrically about the axis, and the lower positive plate corresponding to the position of the upper positive plate is installed on the positive set auxiliary fork;

A straightening shaft is installed in the secondary guide column of the straightening device, a straightening rod is installed on the upper end of the straightening shaft, and a straightening block is installed on the lower end, and the straightening rod and the straightening block are linked through the straightening shaft, One side of the straightening cam is equipped with a cam insert, and the cam insert is provided with a raised shifting block corresponding to the position of the straightening rod on the far end of the straightening cam axis. The movable end is in contact with the cam insert. The straightening block is arranged between the straightening main fork and the straightening auxiliary fork. The shape of the straightening block can drive the straightening main fork and the straightening auxiliary fork to form Scissors open, that is to drive the main fork and the auxiliary fork to move in the opposite direction. The main fork and the auxiliary fork are driven between the working station and the non-working station between conversions,

In the non-working position, the straightening main fork and the straightening auxiliary fork shrink and close under the action of the return spring;

At the working station, the straightening cam pushes the guide column plate to move downward, driving the straightening main fork and the straightening auxiliary fork to sink into the space between the two cigarette boxes of the split packing box, and then the cam insert The shifting block rotates until it touches the straightening rod, which drives the straightening rod to rotate, thereby driving the straightening block to rotate, so that the straightening main fork and the straightening and auxiliary forks rotate in the opposite direction. When the straightening block rotates to the maximum position, The space formed by the outermost four endpoints of the upper dial positive piece and the lower dial positive piece matches the size of the space between the two cigarette packs of the split-type packaging box, thereby positioning the split-type packaging box.

The connecting device includes a roller pin mounted on the guide post plate and a roller mounted on the roller pin, one side of the straightening cam is provided with an annular cam groove along the outer ring of the cam, and the roller is installed on the annular inside the cam groove.

A first damping block is provided on the part where the upper positive plate is in contact with the split packaging box.

A second damping block is provided on the part of the lower positive plate in contact with the split packaging box, and the position of the second shock absorbing block corresponds to that of the first shock absorbing block.

The first shock absorber and the second shock absorber are plastic bumps.

The straightening block is an elongated cube, the middle part of the straightening block is connected with the straightening shaft, and the straightening main fork and the straightening auxiliary fork are all in contact with the movable end of the straightening block.

The lower dial positive piece is a rectangular bottom plate, and when it is in the non-working position, the said straightening main fork and the upper dial positive piece all shrink within the range of the lower dial positive piece.

The shifting block is a protrusion with two slopes, and the slopes are formed by a parabola or a straight line.

Due to the adoption of the above scheme, the present invention adopts a purely mechanical positioning method. In the middle of the filling mechanism, the power of the filling mechanism is used as the input power to provide the power to rotate the straightening cam, so that the positioning of the packaging box can be quickly realized while filling. This device drives the straightening device to move up and down through the straightening cam rotation while the filling mechanism is pressed down, so that when the filling mechanism moves downward, the lower positive piece of the straightening device is driven to fall into the two-fold packaging box. In the space between the cigarette boxes, and then cleverly use the shifting block on the cam insert to drive the straightening lever, so that the straightening block rotates in conjunction, and drives the straightening main fork and the straightening and auxiliary fork to realize scissors-like opening, thereby driving the upper The positive plate is in contact with the inner contour of the packaging box to achieve center positioning. Using this positioning method, it can be strictly synchronized with the main movement of filling, the phase can be intuitively adjusted, and the positioning accuracy is higher than that of the outer contour (the accuracy is within ±0.5mm), and With this mechanical structure, the response time is short, and the working frequency can reach more than 50 times/min. At the same time, it also makes the maintenance simple and reliable; The reliability of the connection is ensured. The shock absorber on the positive plate prevents damage to the packaging box during positioning. The limit block ensures that the main fork and the auxiliary fork can be kept under the contraction force of the return spring In the initial state, the straightening block and the straightening rod are always in the initial position after returning to their original positions, which is convenient for the next positioning.
