Description

Technical Field

[0001] The invention relates to the technical field of building auxiliary equipment, and in particular to a fastener sorting and counting device. Background Art

[0002] Steel pipe scaffolding is an auxiliary equipment commonly used in the construction industry. During the construction of a large building, a large number of steel pipes and fasteners for connecting and fixing steel pipes are needed. The consumption of fasteners is very large, and usually construction units adopt the leasing method to use steel pipes and fasteners. However, when the fasteners are transported to the construction site or sent back to the leasing company, the fasteners need to be sorted and counted. The commonly used method is manual counting, where workers unload the fasteners from the transport vehicles and count the fasteners at the same time. This operation method is time-consuming and labor-intensive. Summary of the invention

[0003] The invention aims to solve the problem of automatic counting of fasteners used in scaffolding in building construction projects, and provides an automatic, high-efficiency, and labor-saving fastener sorting and counting device.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a fastener picking and counting device, including a feeding device, a picking device, a counting device, and a discharging device. The feeding device includes a front roller, a rear roller, a conveyor belt device located between the front roller and the rear roller, two oblique arms located on the sides of the front roller and the rear roller, and a vertical bracket. The two ends of the two oblique arms are respectively hinged to the two ends of the front roller and the rear roller, and one end of the two oblique arms is also hinged to the vertical bracket. A plurality of mutually isolated permanent magnet blocks are provided on the outer circumferential surface of the front roller. The picking device includes a receiving hopper and at least one group of roller groups. The receiving hopper is arranged between the feeding device and the roller group. The roller group includes a first roller, a second roller, and a first roller arranged at the first A belt conveyor between the roller and the second roller, a plurality of magnet rings are provided on the outer circumferential surface of the first roller of the roller group located at the front end, the magnet rings include a plurality of permanent magnet blocks isolated from each other, a plurality of partitions are provided on the belt conveyor, channels corresponding to the magnet rings are formed between the partitions, transverse springs are provided in the channels, the counting device includes a mounting frame, an object recognition camera and a computer processing device, the mounting frame is arranged above the second roller of the roller group at the rear end, the object recognition camera is fixed on the mounting frame, the object recognition camera corresponds to the channel one by one, the discharging device includes a group of transverse belt conveyors, and the discharging device is arranged at the rear end of the roller group at the rear end. This solution can sort and count fasteners. For example, when fasteners returned from the construction site are unloaded from the transport vehicle on the ground, they can be sorted, counted and transported away by this machine. The front roller of the feeding device with a permanent magnet absorbs a batch of fasteners. When it rotates to the upper side, it is blocked by the conveyor belt device (that is, the front roller can pass but the fasteners cannot) and taken away. The fasteners are transported to the rear roller via the conveyor belt device, enter the receiving hopper through the rear roller, and then enter the first roller group of the sorting device. The fasteners are initially separated one by one by the magnet ring and brought onto the belt conveyor for sorting. There are several channels separated by partitions on the belt conveyor, so that the fasteners can pass through in sequence. After further combing by the transverse spring, the fasteners are separated one by one. Finally, after being recognized and counted by the camera and computer, they fall into the transverse belt conveyor and are taken away; the inclined arm of the feeding device can drive the front roller and the conveyor belt device to rotate with the rear roller as the axis, so that the front roller can better contact with the fastener pile and absorb the fasteners; the object recognition camera and computer processing equipment used in this solution can separately identify and count various fasteners, such as cross buckles, movable buckles, connecting buckles and half-piece fasteners.

[0005] As a preference, it further includes a moving device, which includes a walking rubber wheel, a guide wheel, a walking motor, and a machine body, and the feeding device, the picking device, the counting device, and the discharging device are all arranged on the machine body. Due to the changeable terrain of the construction site or the fastener stacking site, this solution can drive the walking rubber wheel through the walking motor and automatically walk to the appropriate working position under the guidance of the guide wheel, and cooperate with the rotatable feeding device to adapt to various working positions.

[0006] Preferably, the roller group is provided with three groups arranged in a front-to-back manner, and the second roller of the roller group located at the front end is located above the first roller of the next roller group. In this solution, the transmission speed of the first roller group can be relatively low, which is conducive to separating the fasteners, while the speed of the second and second roller groups is gradually increased to further accurately separate the fasteners; the fasteners can fall from the second roller of the roller group located at the front end into the next roller group.

[0007] Preferably, the roller groups are respectively provided with drive motors. Different operating speeds can be set for each roller group through different drive motors.

[0008] Therefore, the present invention has the following beneficial effects: (1) automation and high efficiency; (2) it can save a lot of workers' working time and reduce work intensity. BRIEF DESCRIPTION OF THE DRAWINGS
