The utility model provides a positioner is applied to paper products production water line.

In the embodiment of the present invention, as shown in fig. 1 to 5, the positioning device includes a bracket 10, a first electric eye 20 and a second electric eye 30. The bracket 10 is used for being erected on a paper conveying belt (not shown) of a paper product production line, the first electric eye 20 is mounted on the bracket 10 and used for positioning paper, and the second electric eye 30 is rotatably mounted on the bracket 10 and used for scanning the periphery of the paper. The first electric eye 20 and the second electric eye 30 are arranged at intervals, and the distance between the rotation centers of the first electric eye 20 and the second electric eye 30 is smaller than the rotation radius of the second electric eye 30.

Specifically, the first electric eye 20 and the second electric eye 30 are erected above the paper conveying belt through the bracket 10 to scan the paper on the conveying belt. The first electric eye 20 is used for positioning the paper, and the second electric eye 30 is used for scanning the periphery of the paper during rotation to obtain the edge shape of the paper, so as to determine the shape of the paper. Therefore, the position and the shape of the paper can be determined simultaneously, so that the subsequent use of the manipulator for the production line tracking and positioning is facilitated. The distance between the rotation centers of the first electric eye 20 and the second electric eye 30 is smaller than the rotation radius of the second electric eye 30, so as to ensure that the second electric eye 30 can scan the periphery of the paper while the first electric eye 20 determines the position of the paper. The radius of rotation of the second electric eye 30 is the distance from the second electric eye 30 to the center of rotation thereof.

It is worth mentioning that, in the current paper product processing line, CCD vision detection equipment is usually adopted to position the paper on the conveyor belt, but the CCD vision detection equipment is not only high in equipment cost, but also needs operating personnel to have abundant operation experience to debug the equipment, which results in higher labor cost for using the CCD vision detection equipment. For the above reasons, the current paper production cost is high.

In order to solve the above problems, the positioning device of the present application positions the paper by the first electric eye 20 disposed on the support 10, and determines the shape of the paper by the rotatable second electric eye 30, thereby realizing tracking and positioning of the paper instead of a CCD vision inspection device. Because the first electric eye 20 and the second electric eye 30 are scanning photoelectric devices, compared with a CCD vision detection device, the device has the advantages of low cost, simple operation and low requirement for operators. Therefore, the positioning device has the advantages of being simple to operate and low in cost compared with a CCD visual detection device.

Specifically, the first electric eye 20 and the second electric eye 30 are both photo-sensors.

Further, the support 10 includes a support column 11 and a bridge plate 12, wherein the support column 11 is disposed on one side or both sides of the paper conveying belt, the bridge plate 12 is fixed on the support column 11 and at least partially suspended on the upper side of the paper conveying belt, and the first electric eye 20 and the second electric eye 30 are disposed on the bridge plate 12. It will be appreciated that the support posts 11 will both provide support for the bridge 12 and maintain the height of the bridge 12, with the bridge 12 at least partially overhanging the upper side of the paper transport belt. Thus, the first electric eye 20 and the second electric eye 30 are arranged on the bridge plate 12, so that the first electric eye 20 and the second electric eye 30 can scan and position the paper on the conveyor belt conveniently.

Specifically, in the present embodiment, there are two support columns 11, the two support columns 11 are respectively disposed on two sides of the paper conveying belt, and the bridge plate 12 is bridged on the two support columns 11. Of course, the design of the present application is not limited to this, and in other embodiments, only one support column 11 may be provided, or three or more support columns 11 may be provided.

Further, the positioning device of the present application further includes a driving member 40, where the driving member 40 is disposed on the bracket 10 and is used for driving the second electric eye 30 to rotate. It can be understood that the second electric eye 30 is driven to rotate by the driving member 40, and manual work can be replaced by mechanical means, so that the scanning efficiency and accuracy can be improved. The driving member 40 is disposed on the bracket 10, so that the integrity of the positioning device can be improved, and the positioning device can be conveniently assembled and applied on a production line. Of course, the design of the present application is not limited thereto, and in other embodiments, the driving member 40 may not be disposed on the bracket 10, or the second electric eye 30 may be driven to rotate by manual means.

In particular, in the present embodiment, the driving member 40 is a motor. It will be appreciated that the motor is a common drive and that the output shaft of the motor outputs a form of motion that is rotary, the same as the form of motion of the second electric eye 30. Therefore, the motor is selected as the driving member 40 to drive the second electric eye 30 to rotate, which is not only easy to obtain, but also simple to drive. Of course, in other embodiments, other driving devices may be used to drive the second electric eye 30 to rotate, for example, the driving member 40 may also need a device capable of reciprocating by an air cylinder, etc., and the linear motion of the output rod of the air cylinder may be converted into rotation to drive the second electric eye 30 to rotate.

Further, the motor drives the second electric eye 30 to rotate through the speed reducer 70. It can be understood that the motor drives the second electric eye 30 to rotate through the speed reducer 70, and the speed reducer 70 not only can improve the output torque of the motor, but also can slow down the output rotation speed of the motor. Therefore, the rotation stability of the second electric eye 30 is improved, and the rotation speed of the second electric eye 30 is reduced to accurately scan the periphery of the paper. For example, the speed reducer 70 may be a worm gear speed reducer, a planetary speed reducer, a harmonic speed reducer, or the like.

Specifically, the first mounting plate 50 is inserted into the insertion slot of the locking member 60 to be fixed to the output shaft of the motor (in the present embodiment, the output shaft of the speed reducer 70) by the locking member 60. Since the connecting portion 51 is inserted with the slot, the rotating radius of the second electric eye 30 can be adjusted by moving the connecting portion 51, so as to adapt to scanning of paper sheets with different specifications. The limiting portion 53 can limit the position of the locking member 60 during the movement of the connecting portion 51, so as to prevent the first mounting plate 50 from being removed from the slot. Specifically, the stopper 53 protrudes upward from the connecting portion 51. In other embodiments, the position-limiting portion 53 may also be protruded downward from the connecting portion 51, or protruded toward the side of the connecting portion 51, or protruded toward other directions.
