[0002] Chinese utility model application number 202320725815.0 discloses a push-plate bolt feeding system (also known as a nail feeder). Generally speaking, when a push-plate bolt feeding system is in operation, the hopper contains only one specification of screws, and the screws in the hopper are consistent in length and grade. However, incoming materials sometimes become mixed. That is, within a batch of target screws of the same specification, individual screws of a different size or grade may occasionally appear mixed in. (Worker misoperation in a factory environment can also cause screw mixing in the hopper.) Existing push-plate bolt feeding systems are unable to distinguish and remove mixed screws, which undoubtedly affects the work of the next workstation. Utility Model Content

[0003] The technical problem solved by the utility model is to provide a nail feeding machine capable of distinguishing and removing mixed screws.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows: a nail feeding machine includes a frame and a hopper, a push plate feeding mechanism, a straight vibrator and a divider respectively arranged on the frame, and the straight vibrator is provided with a feeding track; the push plate feeding mechanism is used to lift the screws in the hopper to the feeding track; the divider has a feed port and a discharge port, the feed port is connected to the feeding track, and the discharge port is located at the bottom of the divider, and also includes a visual detector and a channel switching assembly respectively arranged on the frame, the visual detector is located above the divider, and the visual detector is used to detect the mark on the top of the screw located in the divider; the channel switching assembly includes a switching drive and a switching plate, the switching drive connects the frame and the switching plate, and a normal material outlet and a mixed material outlet are provided on the switching plate, and the switching drive drives the switching plate to move so that the normal material outlet is connected to the discharge port or the mixed material outlet is connected to the discharge port.

[0005] In one embodiment, a through-beam optical fiber sensor is provided on the material divider, and the through-beam optical fiber sensor is used to detect the length of the screws located in the material divider.

[0006] In one embodiment, the divider includes a shell, a limit block, a supporting block, a first driving member and a second driving member, the limit block and the supporting block are respectively slidably arranged in the shell, the first driving member is connected to the limit block, the limit block has a limit notch for limiting the head of the screw, the limit block is located above the supporting block, the second driving member is connected to the supporting block, the top surface of the supporting block is used to support the interface between the rod and the head of the screw, the feed port is provided on one side of the shell, the head of the screw entering the divider through the feed port is supported on the top surface of the supporting block and is located in the limit notch; the opposing optical fiber sensor is provided on the shell.

[0015] The visual detector can identify the grade mark on the screw head. When the visual detector detects that the screw entering the distributor is a mixed screw (i.e., a screw of non-target grade), the switching drive will drive the switching plate to move so that the mixing outlet on the switching plate corresponds to the discharge outlet of the distributor, thereby allowing the mixed screw to be sent out of the nail feeder through the pipe connected to the mixing outlet. When the visual detector detects that the screw entering the distributor is the target screw, the target screw can be sent to the next workstation through the pipe connected to the normal material outlet.

[0037] Example 1

[0038] Please refer to Figures 1 to 3, the first embodiment of the present utility model is: a nail feeding machine, comprising a frame 1 and a hopper 2, a push plate feeding mechanism 3, a straight vibrator 4 and a divider 5 respectively arranged on the frame 1, and a feeding track 6 is provided on the straight vibrator 4; the push plate feeding mechanism 3 is used to lift the screws in the hopper 2 to the feeding track 6, and the straight vibrator 4 is used to drive the feeding track 6 to vibrate, so that the feeding track 6 can feed stably; the divider 5 has a feed port 51 and a discharge port, the feed port 51 is connected to the feeding track 6, and the discharge port is located at the bottom of the divider 5. The above-mentioned mechanisms included in the nail feeding machine are all possessed by the existing nail feeding machine, and the various mechanisms will not be repeated here. For details, please refer to the technical solution of the Chinese utility model patent with application number 202320725815.0.

[0039] In this embodiment, the nail feeder also includes a visual detector 7 and a channel switching assembly 8 respectively arranged on the frame 1, the visual detector 7 is located above the divider 5, and the visual detector 7 is used to detect the mark on the top of the screw located in the divider 5, and the mark marks the performance level of the screw. The visual detector 7 can be an industrial camera; the channel switching assembly 8 includes a switching drive 81 and a switching plate 82, the switching drive 81 connects the frame 1 and the switching plate 82, the switching drive 81 is a cylinder, an electric push rod, a motor screw assembly or other driving parts, and a normal material outlet 83 and a mixing outlet 84 are provided on the switching plate 82, the switching plate 82 is located below the divider 5, and the switching drive 81 drives the switching plate 82 to move so that the normal material outlet 83 is connected to the discharge port or the mixing outlet 84 is connected to the discharge port.

[0040] Preferably, the divider 5 is provided with a through-beam fiber optic sensor (not shown in the figure), which is used to detect the length of the screws located in the divider 5. At this time, the nail feeder can not only distinguish and remove mixed screws according to the performance level marked on the screws themselves, but also distinguish and remove mixed screws according to the length of the screws, thereby making the nail feeder have higher application value.

[0041] Specifically, the divider 5 includes a shell 52, a limit block 53, a supporting block 54, a first driving member 55 and a second driving member 56. The limit block 53 and the supporting block 54 can be slidably arranged in the shell 52 respectively. The first driving member 55 is connected to the limit block 53. The limit block 53 has a limit notch 531 for limiting the head of the screw. The limit block 53 is located above the supporting block 54. The second driving member 56 is connected to the supporting block 54. The top surface of the supporting block 54 is used to support the interface between the rod and the head of the screw. The feed port 51 is provided on one side of the shell 52. The head of the screw entering the divider 5 through the feed port 51 is supported on the top surface of the supporting block 54 and is located in the limit notch 531; the corresponding optical fiber sensor is provided on the shell 52.

[0042] When the material distributor 5 is working, the first driving member 55 and the second driving member 56 act at the same time, so that the screw carried by the supporting block 54 moves to the top of the material outlet, and determines whether the screw currently above the material outlet is the target screw based on the detection result of the visual detector 7 and the judgment result of the opposing optical fiber sensor. If it is, the second driving member 56 first drives the supporting block 54 to reset. At this time, since the limit block 53 is still limiting the head of the screw, the screw will not follow the supporting block 54 to reset. When the supporting block 54 and the screw distributor are separated, the screw will not be reset. After the screw is separated, it falls under the influence of gravity and then falls into the pipe connected to the normal material outlet 83. If not, the switching drive member 81 drives the switching plate 82 to move, so that the mixed material outlet 84 is aligned with the discharge port of the distributor 5. Then, the second driving member 56 first drives the supporting block 54 to return to its original position. At this time, since the limit block 53 still limits the head of the screw, the screw will not follow the supporting block 54 to return to its original position. When the supporting block 54 is separated from the screw, the screw falls under the influence of gravity and then falls into the pipe connected to the mixed material outlet 84. In this way, the mixed material screw is eliminated.

[0043] Specifically, the shell 52 is provided with a mounting hole 521 for installing the opposing optical fiber sensor. The mounting hole 521 passes through the opposite sides of the shell 52. The mounting hole 521 corresponds to the discharge port in the vertical direction. In this embodiment, the axial direction of the mounting hole 521 is perpendicular to the sliding direction of the limit block 53.

[0044] To ensure the working stability of the divider 5, the divider 5 also includes a pressure block 57 provided on the shell 52. The pressure block 57 is set corresponding to the feed port 51. The setting of the pressure block 57 can ensure that the head of the screw can smoothly enter the limiting notch 531.

[0045] The first driving member 55 is a cylinder, an electric push rod, a motor screw assembly or other driving members. Similarly, the second driving member 56 is a cylinder, an electric push rod, a motor screw assembly or other driving members.

[0046] In detail, the feed track 6 includes two inclined support bars 61 spaced apart, and a material channel is formed between the two inclined support bars 61. The inclined support bars 61 can support the head of the screw, and the rod of the screw slides along the material channel. The nail feeder of this embodiment also includes a cleaning component 9 connected to the frame 1. The cleaning component 9 is located below the feed track 6. The top of the cleaning component 9 is provided with a through-groove 91 through which the rod of the screw transported by the feed track 6 passes. The through-groove 91 corresponds to the material channel. The cleaning component 9 is used to clean the screw passing through the through-groove 91. In this embodiment, the cleaning component 9 includes a vacuum generator 92. The cleaning component 9 uses negative pressure suction to remove particulate matter attached to the rod of the screw. In other embodiments, the cleaning component 9 can also be a brush or the like.

[0047] The above are merely optional embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the practical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
