Specifically, the two sets of feeding mechanisms 8 are both mounted on the fixing base 7, and the fixing base 7 is mounted on the machine 100 so that the feeding module 400 is integrally and fixedly mounted on the machine 100.

Each set of the feeding mechanisms 8 includes a feeding seat 81, a discharging roller 82 for discharging the label tape 80, a guide roller 83 for guiding the label tape 80, a separating table 84 for separating the label from the label tape 80, a tension roller 85 for tensioning the label tape 80, and a winding roller 87 for winding the label tape 80, wherein the receiving table 6 is fixedly provided on the feeding seat 81 in front of the separating table 84 in the conveying direction of the label tape 80. The feeding mechanism 8 further includes a pressing cylinder 86 for pressing the tension roller 85 against the label tape 80.

The two feeding mechanisms 8 are arranged independently of each other, and a distance adjusting mechanism 9 for adjusting the relative positions of the two feeding mechanisms 8 in the direction parallel to the first direction (X direction) and a height adjusting mechanism (not shown) for adjusting the relative height positions of the two feeding mechanisms in the vertical direction are arranged between the two feeding mechanisms 8. Here, the spacing adjustment mechanism 9 includes a lead screw 91 extending in the X direction, a driving mechanism for driving the lead screw 91 to rotate, and a nut engaged with the lead screw 91 is fixed to the bottom of one of the feed blocks 81. The driving mechanism adopts a mode of adding a synchronous belt mechanism to the driving motor 92, and is more beneficial to compact layout in space.

Therefore, when the multi-station automatic labeling equipment works, workpieces to be labeled are transmitted to the labeling working area from the workpiece transmission module 300 along the X direction, two groups of first labeling stations and second labeling stations corresponding to the two groups of labeling modules 500 are formed on the workpieces, and the two groups of labeling modules 500 respectively perform labeling operation, namely, labeling processing on 4 labeling stations can be realized simultaneously.

The operation of the labeling apparatus will be described by taking the cooperation of one labeling module 500 and the feeding module 400 as an example:

when the distance between the two label suction working heads 3, the distance between the first feeding station and the second feeding station, and the distance between the first labeling station and the second labeling station are the same, the labeling module 500 moves to the upper side of the feeding module 400, the two label suction working heads 3 correspond to the first feeding station and the second feeding station, respectively, the motor rotates forward to move the first belt section 231 downward, so that the corresponding label suction working head 3 descends to the first feeding station to suck the label, then the motor rotates backward to lift the first belt section 231, at this time, the second belt section 232 descends until the second feeding station sucks the label, then the motor rotates forward again, the second belt section 232 rises, so that the two label suction working heads 3 have the same height or at least cannot interfere with other components in the process of Y-direction movement, the whole labeling module 500 is driven to move along the Y-direction, thereby reaching the upper part of the workpiece to be labeled. The two groups of label absorbing working heads 3 correspond to the first labeling station and the second labeling station respectively, and similar to the process of label absorption, the two groups of label absorbing working heads 3 alternately descend and finish labeling operation on the two labeling stations respectively. Therefore, the labeling operation of 2 stations can be realized by one Y-directional movement stroke.

When the distance between two groups of label-absorbing working heads 3, the distance between the first feeding station and the second feeding station, and/or the distance between the first labeling station and the second labeling station are different, it is determined that a first distance difference exists between the distance between the first feeding station and the second feeding station and the distance between the two groups of label-absorbing working heads 3, and it is determined that a second distance difference exists between the distance between the first labeling station and the second labeling station and the distance between the two groups of label-absorbing working heads 3, then:

when the label is sucked, firstly, one label sucking working head 3 is made to correspond to the position of the first feeding station, and the motor rotates forwards to make the label sucking working head 3 descend to suck the label on the first feeding station; subsequently, the motor is reversed, the label sucking working head 3 sucking the labels is lifted, the other label sucking working head 3 is lowered, meanwhile, the whole labeling module 500 moves along the Y direction, so that the other label sucking working head 3 moves by the displacement of the first distance difference to reach the position above the second feeding station, and the motor is continued to be reversed to enable the label sucking working head 3 to be lowered continuously to suck the labels from the second feeding station. Then, the motor rotates forward again, so that the whole labeling module 500 moves along the Y direction to the upper part of the workpiece to be labeled after the two groups of label absorbing working heads 3 reach the same height.

During the labeling operation, similar to the label suction, after one label suction working head 3 firstly labels the first labeling station, the whole labeling module 500 moves along the Y direction by the displacement of the second distance difference, so that the other label suction working head 3 reaches the second labeling station for labeling. After the two labeling stations finish labeling, the whole labeling module 500 moves along the Y direction to reach the upper side of the feeding module 400 for the next label sucking and labeling operation.
