Description

Technical Field

[0001] This application belongs to the technical field of screw feeding, and particularly relates to a cut screw and feed screw mechanism. Background Art

[0002] During the production process of screws, the produced screws need to be conveyed and discharged. However, there will be some defective products that do not meet the requirements. For example, when assembling components, screws of a specified length are often required. Most of the existing rejection mechanisms for screw feeding mechanisms are manual screening or screening by a screening machine to ensure that the bolts fed into the automatic screw driving machine are of the required specifications. However, the efficiency of manual screening is not high, and the screening by a screening machine requires an additional screening process, which needs an independent process. In addition, a loading and unloading mechanism, etc. are also required, resulting in a complex structure and high cost of this screening method. Therefore, an improved technology is proposed. Content of the Utility Model

[0003] The technical problem to be solved by this utility model is: to solve the deficiencies of low efficiency of manual screening and high cost of screening by a screening machine in the prior art, and thus provide a cut screw and feed screw mechanism.

[0004] The technical solution adopted by this utility model to solve its technical problems is:

[0005] A cut screw and feed screw mechanism, comprising:

[0006] A machine shell, on the upper surface of which there is a feed channel allowing screws to enter the machine shell from one side of the machine shell, and the lower end of the feed channel communicates with the inside of the machine shell;

[0007] An upper positioning mechanism, which can position the screws in the feed channel and release the screws. When the screws are released, the screws enter the machine shell,

[0008] Two discharge channels, which respectively discharge good products and defective products;

[0009] A discharge switching mechanism, which switches the position of the screws entering the machine shell so that the screws are discharged into one of the two discharge channels;

[0010] A detection structure, which detects whether the screws in the feed channel are good products. According to the quality of the products, the discharge switching mechanism acts to switch different discharge channels.

[0011] Furthermore, the upper positioning mechanism includes a moving plate, a first driving mechanism, and a material guiding channel. The moving plate is movably arranged on the inner top side of the casing. The first driving mechanism is installed on one side of the casing. One end of the first driving mechanism is connected to the moving plate. A guiding channel for guiding the nails entering the feeding channel into the two discharging channels is formed on the moving plate. One end of the guiding channel is provided with a feeding port allowing the nails entering the feeding channel to enter the guiding channel. The other end of the guiding channel is an opening through which the screws can fall. The material guiding channel is communicated with the opening. The guiding channel and the material guiding channel cooperate to fix the screws at the position of the moving plate. The first driving mechanism drives the moving plate to move to change the positions of the material guiding channel and the guiding channel, thereby improving the position of the nails.

[0012] Furthermore, the discharging switching mechanism includes a switching block and a second driving mechanism. A switching channel is formed on the switching block. The switching block is installed inside the casing. The switching block blocks the two discharging channels. The second driving mechanism drives the switching block to move to change the corresponding communication between the switching channel and the two different discharging channels.

[0013] Furthermore, the switching block is slidably installed on the inner bottom surface of the casing. Slide holes are formed at both ends of the switching block. Positioning rods are slidably arranged in the slide holes. The positioning rods are fixed inside the casing.

[0014] Furthermore, the detection structure includes two sensors. The sensors are preferably photoelectric sensors and are symmetrically installed on both sides of the casing for detecting the screws located in the feeding channel. Through holes allowing the detection light source of the sensors to pass through are formed inside the casing.

[0015] Furthermore, the two discharging channels are two discharging cylinders. A blowing structure facilitating the discharging of materials is further provided on the discharging cylinders. The flowing direction of the gas blown out by the blowing structure is obliquely downward, which does not block the discharging of the screws inside the discharging cylinders. At the same time, the blown gas can assist the discharging of the screws.

[0016] The beneficial effects of the present utility model are as follows:

[0017] 1. The product of the present utility model has a simple structure, a compact overall structure, does not occupy space, and can be directly installed on the feeding conveyor line without additional workstations and some screening equipment with complex structures and large space occupation.

[0018] 2. By setting up detection equipment, the length of the screws can be directly detected during feeding to check whether it meets the required rules, and the unqualified screws with incorrect lengths can be directly removed. Description of the Drawings

[0032] The two discharging channels 30 discharge qualified products and unqualified products respectively.

[0033] The upper positioning mechanism 20 can position the screws in the feeding channel 11 and release the screws. After the screws are released, they enter the machine housing 10. The upper positioning mechanism 20 includes a moving plate 21, a driving mechanism one 22, and a guiding channel 23. The moving plate 21 is movably arranged on the inner top surface of the machine housing 10. The driving mechanism one 22 is installed on one side of the machine housing 10, and one end of the driving mechanism one 22 is connected to the moving plate 21. A guiding channel 24 for guiding the nails in the feeding channel 11 into the two discharges 30 is provided on the moving plate 21. One end of the guiding channel 24 is provided with a feeding port 25 for allowing the nails entering the feeding channel 11 to enter the guiding channel 24, and the other end of the guiding channel 24 is an opening 26 for allowing the screws to fall. The guiding channel 23 communicates with the opening 26. The guiding channel 24 and the guiding channel 23 cooperate to fix the screws at the moving plate 21. The driving mechanism one 22 drives the moving plate 21 to move to change the positions of the guiding channel 23 and the guiding channel 24, thereby improving the positions of the nails. The driving mechanism one 22 is a linear driving device such as a cylinder or a hydraulic cylinder.

[0034] The discharging switching mechanism 40 switches the positions of the screws entering the machine housing 10 so that the screws are discharged through one of the two discharging channels 30. The discharging switching mechanism 40 includes a switching block 41 and a driving mechanism two 42. A switching channel 43 is provided on the switching block 41. The switching block 41 is installed inside the machine housing 10. The switching block 41 can block the two discharging channels 30. The driving mechanism two 42 drives the switching block 41 to move to change the corresponding communication between the switching channel 43 and different two discharging channels 30. The driving mechanism two 42 is a linear driving device such as a cylinder or a hydraulic cylinder.

[0035] The switching block 41 is slidably installed on the inner bottom surface of the machine housing 10. Slide holes 44 are provided at both ends of the switching block 41, and positioning rods 45 are slid in the slide holes 44. The positioning rods 45 are fixed inside the machine housing 10.

[0036] The detection structure 50 detects whether the screws in the feeding channel 30 are qualified products. According to the quality of the products, the discharging switching mechanism 40 operates to switch different discharging channels 30. The detection structure includes two sensors 51, preferably photoelectric sensors, which are symmetrically installed on both sides of the machine housing 10 to detect the screws located in the feeding channel 11. Through holes 52 allowing the detection light sources of the sensors 51 to pass through are provided in the machine housing 10.

[0037] The two discharging channels 30 are two discharging cylinders 31. An air blowing structure 32 facilitating the discharge of materials is further provided on the discharging cylinder 31. The flowing direction of the gas blown by the air blowing structure 32 is obliquely downward, which does not block the discharging of the screws in the discharging cylinder 31, and at the same time, the blown gas can assist the discharging of the screws.

[0038] When the product of the present utility model is specifically used:

[0039] The screw feeding mechanism transports the screws into the feeding channel 11. At this time, the detection structure 50 detects whether the screws in the feeding channel 30 are qualified products. According to the quality of the products, the discharging switching mechanism 40 operates, and the driving mechanism 22 drives the moving plate 21 to move, that is, drives the opening 26 of the guiding channel 24 to coincide with the screws. At this time, the screws are no longer restricted and then fall into the guiding channel 23 from the opening under the action of gravity, and finally fall into the switching channel 43 of the switching block 41. The driving mechanism 42 drives the switching block 41 to move, so that the switching channel 43 is aligned with the corresponding discharging channel 30 to discharge the screws.
