As shown in fig. 1, in a conventional strip box facial tissue conveying line, facial tissue 10 needs to be glued on a gluing machine and then conveyed to an input position 11 on a conveying belt 14, then the conveying belt 14 travels a fixed length stroke L in one processing cycle, enters an output position 12 to wait, after a vision system photographs and identifies a whole piece of facial tissue on the output position 12, an ash plate 20 waiting on one side of the output position 12 is grabbed by a manipulator 13 and transferred to the facial tissue waiting on the output position 12 at the moment to be pasted. In order to improve the production efficiency, a plurality of pieces of facial tissue are often output at the same time, however, when the pasting machine outputs the glued facial tissue, the state of the facial tissue becomes soft after being wetted by glue, so that the facial tissue is arched or curled when being peeled from the pasting machine, the facial tissue is finally sucked and adhered to the conveying belt 14 by the air suction holes on the conveying belt 14 and is flatly laid, and at the moment, the phenomenon that the heads of the facial tissue are not aligned occurs. In some solving means, a secondary positioning station is added, and the facial tissue is flapped and tidied on the output position 12 through an auxiliary positioning machine; in other solutions, if the vision system cannot identify the misaligned facial tissue, the vision system determines that the facial tissue is processed into a defective product continuously regardless of the defects, and the defective product is removed in the next quality inspection process.
Referring to fig. 2-4, the solution provided by the present invention is to preset a standard area B in the shot area of the output bit 12, wherein a reference line L is set at the head edge of the standard area B0Wherein the reference line L0The distance between the head of the facial tissue in the standard pose at the moment is a reference value S.
The servo system drives each beat of the conveying belt 14 to travel by a fixed-length stroke L, the rubber-faced paper carried by the conveying belt 14 is just parked in a photographing area after N whole beats, the rubber-faced paper is repeatedly observed and debugged to a proper position in the photographing area, the rubber-faced paper deviates to the head direction by a distance S to obtain the reference line, and then the tail direction of the rubber-faced paper symmetrically deviates by the distance S to obtain the standard interval B(ii) a Then, a detection sensor is set at the head end line position of the last beat of the reciprocal thereof. Then the sensor and reference line L are detected0The distance between is L + S.
When the head of the facial tissue 10 is detected to pass through, a passing signal is sent to the servo system, and the servo system calculates the distance between the currently passed facial tissue and the detection point before the beat is started.
Wherein, the extreme value is 0, namely a beat, the conveying takes away a fixed length stroke L, the head part of the facial tissue is just level with the detection line, therefore, the facial tissue passes through a beat, and the head part of the facial tissue is just far away from the reference line L after passing through a fixed length stroke L0Is S, is the standard pose. The manipulator can grab the gray board to stick the surface paper. When the servo system calculates that the distance between the current passing facial tissue and the detection point at the start of the beat is S1When S is present1When the beat is more than or equal to S, after the beat or N beats are finished, the facial tissue cannot fall into the standard interval B, the mechanical arm does not work, and the servo system waits for driving the conveying belt to positively compensate S towards the head direction1Then, the machine enters the standard interval B, the vision system can recognize the coordinate signal of the supplied facial tissue in the standard interval to the manipulator 13, and the vision system can grab the gray plate 20 to adhere the supplied facial tissue. On the contrary, if S1And if the difference is less than S, no compensation is needed, and the visual system finds that the supplied facial tissue material is in the standard interval.
If S is shown in FIG. 31When the system calculates S1The absolute value of (D) is still greater than or equal to S, then the conveyer belt needs to reversely retreat | S1I, enabling the facial tissue beyond the standard interval to return to the standard interval B; when the absolute value is less than S, no compensation is needed.
Furthermore, each facial tissue conveying path is provided with a detection sensor, when the number of facial tissues conveyed on the conveying belt is large, the projection of each detection sensor on the conveying belt is connected into a connecting line, and the connecting line forms a detection line L1. The servo system calculates different S according to the passing signal of each facial tissue1～SN,And then S is1～SN,And sequencing according to numerical values from small to large, when the absolute value of the numerical value is larger than the reference value, correspondingly compensating by the conveying system, then returning the compensated length by the conveying system, and comparing the next numerical value. Or the like, or, alternatively,
the calculation center calculates different S according to the passing signal of each facial tissue1～SN,And then S is1～SN,Sequencing according to numerical values from small to large, compensating by the conveying system when the reference value of the numerical values is larger than the reference value, and compensating by the conveying system SN-SN-1Until the last compensation is completed, and back off by SNThe distance of (d) returns to the original position.
With continued reference to fig. 2, an assembly line of gray board and facial tissue of enclosing frame includes: the facial tissue pasting mechanism is used for providing a plurality of pieces of facial tissue 10 with glue on the pasted surfaces to the input positions 11, and the glued surfaces of the facial tissue 10 are upwards and flatly laid on the input positions 11; the conveying belt 14 carries the lines of facial tissues 10 to the output position 12 for waiting; a gray board feeding device for providing a gray board 20 to the facial tissues waiting in the output position 12; and the mechanical arm 13 grabs the gray board 20 according to the feedback of the visual system and sticks the gray board to the surface paper with the adhesive to form an adhesive body 30.
