Detailed Description

The present invention will be described in further detail with reference to specific examples.

Example (b):

as shown in fig. 1 to 3, the utility model discloses a feeding conveyor for paper clamp plate collecting machine, include first conveying district 21 and the second conveying district 22 that sets up along the direction of delivery front and back, second conveying district 22 is used for making small plate horizontal migration, the outlet side of second conveying district 22 is equipped with barrier strip 23, first conveying district 21 includes the conveying roller in the takeout that a plurality of levels set up side by side, the equal perpendicular to direction of delivery of the axis of conveying roller in the takeout, and be equipped with the unit 212 in the takeout that gets that a plurality of structures are the same on the conveying roller, unit 212 in getting is the thick rotator structure of thin both sides in the middle of getting, the structure mirror symmetry of unit 212 in getting and the axis of conveying roller in its mirror image plane perpendicular to takeout. The feeding and conveying device 2 is positioned in the upper plate area 11 of the paper clamping and plate collecting machine 1 and is used for feeding small plate pieces. The self-centering feed roller is a drive roller driven by a motor. The small pieces, after entering the first conveying zone 21, fall onto the extraction unit 212. When the self-centering conveying roller rotates, the small plate piece is conveyed towards the direction of the second conveying area 22, the two sides of the small plate piece move towards the sunken middle part of the centering unit 212 due to self weight of the small plate piece, and therefore after passing through a plurality of self-centering conveying rollers, the angle of the small plate piece can be automatically adjusted to be located on the mirror surface of the centering unit 212 through the symmetry axis of the small plate piece, the stop position of the small plate piece when reaching the second conveying area 22 is controlled, then the small plate piece is horizontally conveyed through the second conveying area 22, and the stop strip stops in front of the stop strip 23. Because the barrier strip 23 provides a front reference for the small plate, the small plate can determine the position along the conveying direction when contacting the barrier strip 23, and each small plate can find its own position, so that the suction cup assembly 14 of the paper clamping and plate collecting machine 1 can accurately suck the small plate.

As shown in fig. 3, the middle unit 212 includes two conical surfaces 2121 with the same taper. The conical surface 2121 is easy to process and can meet the requirement that the middle unit 212 is a rotator structure with a thin middle part and two thick sides.

As shown in fig. 3, the self-centering conveying roller includes a roller shaft 211 passing through the centering unit 212, and both sides of the roller shaft 211 are provided with pressing rings 23 for clamping and fixing all centering units 212 to the roller shaft 211, and the pressing rings 23 are fixed to the roller shaft 211 by screws (not exposed) passing through in the radial direction. Thus, the axial position of the all-taking unit 212 along the roller shaft 211 can be arbitrarily adjusted within the range of the roller shaft 211, and the conveying directions of the front and rear self-taking conveying rollers are made to coincide.

As shown in fig. 2 and 4, the second conveying section 22 includes a plurality of conveying rollers 221 arranged horizontally side by side, and the conveying rollers 221 are cylindrical and have an axial direction perpendicular to the conveying direction. After the small plate member reaches the second conveying section 22, the small plate member is horizontally moved with the highest point of the conveying roller 221 as a height reference. The second transport area 22 allows the small plate to move horizontally because the small plate is in a horizontal position when the suction assembly 14 sucks the small plate. In the second conveying section 22, not only the conveying roller 221 but also a mechanism such as a conveying belt that can horizontally move the object may be used.

As shown in fig. 4, each three sensors (a first sensor 231, a second sensor 232, and a third sensor 233) for sensing the positions of the small plate members are arranged in a group on the barrier rib 23, and a plurality of adjusting devices 24 for adjusting the positions of the small plate members perpendicular to the conveying direction are arranged in the second conveying area. In order to allow the position of the small plate member to be more closely controlled, three sensors are used for sensing, and if the small plate member is sensed by the first sensor 231, the position is too far to the right, and the adjusting device 24 adjusts the position of the small plate member to the left; if the small plate member is sensed by the third sensor 233, the position is too far to the left, and the adjusting device 24 adjusts the position of the small plate member to the right; when the small plate member is sensed by the second sensor 232, it can be indicated that the small plate member is accurately positioned. This further ensures that the suction cup assembly 14 is sucked to the small plate.

As shown in fig. 4, the adjusting device 24 includes an elevating mechanism (not exposed) and an adjusting mechanism 24, the adjusting mechanism 241 includes a plurality of adjusting belts 241 interposed between adjacent conveying rollers 221 and a pulley 242 for controlling the adjusting belts 241 to finely adjust the position of the small plate member along the direction parallel to the axis of the conveying rollers 221, and the elevating mechanism is used for adjusting the height of the adjusting mechanism 24 to control the highest point of the adjusting belts 241 to be switched between the highest point higher than the conveying rollers 221 and the highest point lower than the conveying rollers 221. Before the small plate pieces enter the second conveying area 22, the adjusting mechanism 24 needs to descend below the height of the highest point of the conveying roller 221, otherwise the adjusting mechanism 24 can touch the small plate pieces to deviate the small plate pieces again; only after the small plate pieces enter the monitoring range of one group of sensors, the lifting mechanism controls the adjusting mechanism 24 to ascend, the small plate pieces are supported by the adjusting belts 241, and then adjustment is completed. Thus, the core function implementation of the device is not influenced.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
