Hardware product conveyer

Technical Field

The invention belongs to the technical field of conveying supplied objects, and particularly discloses a hardware product conveying device.

Background

The screw is a fastener for fixing objects, and at present, the screw package is generally produced by packaging the screw through a paper box or a plastic paper bag. But due to the large production volumes, most screws are scattered in the packing box or bag. A large number of screws are randomly distributed in the package, and the end parts of the self-tapping screws in the screws are of pointed structures, so that the screws are easy to penetrate through the packaged product in the transportation process, and the screws are scattered from the packaged product. Therefore, when the screws are used for mass production and packaging, the sequence and the positions of the screws on the packaged product need to be reasonably arranged, so that the space is fully utilized, and the screws are uniformly distributed in the packaged product.

For example, the chinese utility model (CN207956148U) discloses an automatic screw packaging machine, wherein a frame of the packaging machine is provided with a frame front side plate and a frame top plate, the upper surface of the frame top plate is provided with an automatic screw counting machine, and a screw discharging conduit is provided at a discharging port of the automatic screw counting machine; the rubber film conveying assembly at the upper end part of the packaging machine frame comprises a conveying support frame, a rubber film discharging roller and a conveying roller set, wherein the conveying roller set comprises a driving conveying roller, a driven conveying roller and a conveying driving motor; the packaging machine frame is provided with a bending guide plate on the front end side of the lower end part of the screw discharge guide pipe, a hot-pressing closing-in component is arranged between the bending guide plate and the front side plate of the frame, the hot-pressing closing-in component comprises a bottom closing-in mechanism and a side closing-in mechanism, the bottom closing-in mechanism comprises a left hot pressing plate, a right hot pressing plate and a hot pressing plate driving cylinder, and the side closing-in mechanism comprises a left side hot pressing wheel, a right side hot pressing wheel.

Although the screws are packaged, the screws are arranged in the packaging bag in a disordered manner after being packaged, and space resources of the packaging bag are wasted to a great extent.

Disclosure of Invention

The invention aims to provide a hardware product conveying device to solve the problem that tapping screws cannot be arranged in order during production and packaging.

In order to achieve the purpose, the basic scheme of the invention is as follows: a hardware product conveying device comprises a rack, wherein a sorting mechanism and a guide mechanism are arranged on the rack, the sorting mechanism comprises a feed hopper, a driving motor and a sorting wheel, the feed hopper is arranged on the rack, the sorting wheel is arranged under the feed hopper, the top end of the circumferential side wall of the sorting wheel is tangent to the bottom surface of the feed hopper, the driving motor drives the sorting wheel to rotate, a plurality of blind holes with the same size are uniformly distributed on the circumferential side wall of the sorting wheel, the axial direction of each blind hole is parallel to the radial direction of the sorting wheel, a magnet is arranged on the bottom surface of each blind hole, an annular groove is formed in the axial side wall of the sorting wheel, the annular groove is communicated with the blind holes, a separating plate is inserted in;

the guide mechanism comprises two groups of guide plates, the outlets of the guide plates are positioned at the same horizontal height, the top ports of the guide mechanisms are abutted against the circumferential side wall of the sorting wheel, the top ports of one group of guide plates are abutted against the right lower part of the sorting wheel, the topmost end of the sorting wheel is used as an angle measurement original point, and the top ports of the other group of guide plates are abutted against the circumferential side wall of the sorting wheel at a position larger than 90 degrees and smaller than 180 degrees.

The working principle and the beneficial effects of the basic scheme are as follows: after the tapping screw enters the feed hopper, the tapping screw slides into the blind hole of the sorting wheel under the guiding action of the feed inlet. The self-tapping screw can be in two forms after entering the blind hole, wherein the nut of the self-tapping screw is abutted against the bottom surface of the blind hole, and the self-tapping screw can be adsorbed by the magnet on the bottom surface of the blind hole due to the large contact area between the nut and the bottom surface of the blind hole; the other mode is that the pointed end of the tapping screw is abutted against the bottom surface of the blind hole, and at the moment, because the contact area of the pointed end and the bottom surface of the blind hole is small, the tapping screw cannot be firmly adsorbed by the magnet. The sorting wheel rotates under the rotation of the driving motor, and then the self-tapping screws with the pointed ends abutting against the bottom surface of the blind holes firstly slide out of the blind holes and fall to one group of guide plates; when the nut abuts against the tapping screw on the bottom surface of the blind hole and passes through the bottommost part of rotation, the nut can contact the separating plate inserted into the annular groove, and then the tapping screw can slide onto the other group of guide plates under the blocking of the separating plate. Eventually, the tapping screws of different shapes fall off the guide plate at the same height.

Compare with the screw transportation packing plant among the prior art, this scheme can utilize simple runner mechanism, just can divide into positive and negative two kinds of states with self-tapping screw and pile up the pendulum and put, has reached the effect of maximize utilization in limited space to in making self-tapping screw tip end evenly distributed and packing plant, make packing plant atress even, furthest reduces and damages packing plant.

Further, be equipped with the cam in driving motor's the drive shaft, the radial outer wall of cam offsets in the feeder hopper bottom, through compression spring interconnect between feeder hopper top and the frame. The driving motor drives the cam to rotate, the cam further pushes the feed hopper to shake, self-tapping screws in the feed hopper fall out of the feed hopper, and the screws are prevented from blocking the feed hopper.

Further, the one side that the separation plate is close to the sorting wheel axle center is the arc surface, the arc surface cooperates in the side that the ring channel is close to the axle center, the face that the separation plate was kept away from the separation plate is crossing with the arc surface. The circular arc surface in the scheme is convenient for the separation plate to slide relatively in the annular groove when the separation wheel rotates.

Further, the surface of the separation plate, which is far away from the separation plate, is intersected with the arc surface. The surface of the separating plate far away from the separating plate is intersected with the arc surface, so that the separating plate can shovel the nut of the self-tapping screw more easily, and the nut is separated from the magnet.

Furthermore, one surface of the annular groove close to the axis is coplanar with the bottom surface of the blind hole. Above-mentioned scheme is convenient for the bottom department of meeting of separation plate and self-tapping screw, and then is convenient for later self-tapping screw's separation.

Further, the deflector includes first slide and second slide, be 90 degrees contained angles between first slide and the second slide, first slide cross-section width is 4mm to 20mm, second slide cross-section width is greater than 20 mm. Above-mentioned scheme is convenient for self-tapping screw adjustment slip direction, and then reaches and drops to packing plant in from same vertical position.
