Description

TECHNICAL FIELD

[0001] The present application relates to the field of bar detection and boxing machinery. BACKGROUND

[0002] The detection of small bars, such as the detection of metal bars with short length and small diameter, requires the detection of various surface defects such as pinholes, scratches, surface grooves, surface contamination, water stains, plating bubbles, and short plating, as well as various size defects such as small diameter, large and small heads, no chamfer, short length, long length, flat material, and unqualified straightness. In the detection process, unqualified bars need to be screened out, and qualified products can be directly boxed for subsequent packaging.

[0003] At present, although with the rapid development of intelligent technology, many traditional processes that mainly rely on manual visual detection, screening, and boxing are gradually being replaced by operation processing devices with automation, intelligence, and visual processing. However, some existing detection devices are still relatively ordinary and single-function detection devices, which are difficult to screen out and remove all products with different defects, resulting in the presence of unqualified products with other defects in finished products, which is difficult to meet the detection requirements. For the above-mentioned small metal bar detection application, there is no mechanical device that can be directly used for effective detection, screening, and boxing of such bars from the conveying to the visual detection, to the rejection and boxing processes. Therefore, there is an urgent need for a device that can be used for surface detection, size detection, rejection, and boxing of small bars, as well as an operation processing method that can reliably achieve the desired effect to meet the production needs of such small bar products.

[0042] In order to further explain the technical solutions of the present application, the present application will be described in detail below through specific examples.

[0043] The detection and boxing equipment for small rod materials disclosed in the present embodiment comprises a machine base (part of the panel is shown in the figure) and a feeding conveying device 1, a conveying, detecting and removing device 2 and a discharging and boxing device 3 installed on the machine base. Figure 1 、 Figure 2 、 Figure 3 and Figure 4 、 Figure 5 、 Figure 6 The conveying, detecting and removing device 2 comprises a conveying belt detecting and removing device 4, a distributing device 5 and a rotary disc detecting and removing device 6, and the structures of these devices are different from those of the prior art. In addition, the structure of the discharging and boxing device 3 is also different. The specific structural settings and position connection relationships of each device will be described in detail below in combination with the drawings.

[0044] The input end of the conveying belt detecting and removing device 4 is connected to the output end of the feeding conveying device 1, and the input end of the distributing device 5 corresponds to the output end of the conveying belt detecting and removing device 4. Figure 1As shown, including the erection on the base with driving mechanism driven conveyor belt 41, fixed on the base corresponding to the conveyor belt 41 above at least a group of first visual inspection equipment 42 and corresponding to the first visual inspection equipment 42 and cloth device 5 between the conveyor belt 41 side on the first rejection material device 43. The conveyor belt 41 is provided with the axis direction of the bar material consistent with the conveying direction of the conveyor belt 41 and can be orderly one by one to transport forward through the first visual inspection equipment 42 shooting range and the first rejection material device 43. The elongated bar slot 44, here the slot width of the elongated bar slot 44 is suitable for one bar to be easily embedded, and the width of the same section cannot be embedded, and the depth is set to facilitate the rolling out of the elongated bar slot 44 during the rejection operation and not easy to roll out of the elongated bar slot 44 without rejection operation. In order to improve the conveying efficiency, the elongated bar slot can be provided with multiple strips side by side, such as two strips shown in the figure, and the first visual inspection equipment 42 is correspondingly provided with two groups, which are respectively corresponding to one elongated bar slot 44 for shooting detection. Since it is one by one linear conveying, some size related detection can be mainly carried out here. The first rejection material device 43 is a blowing rejection mode in the figure, and a long blowing nozzle port is correspondingly arranged on one side of the elongated bar slot 44 to be rejected. After the bar material is input from the feeding conveying device 1 (here the input can be provided with a photoelectric switch 45 for material detection between the guiding embedding block 46 and the first visual inspection equipment 42 as shown in the figure, so as to carry out subsequent visual image processing for problem treatment and investigation in conveying), the unqualified products after passing through the first visual inspection equipment 42 will be blown when reaching the corresponding first rejection material device 43 station, and the corresponding bar material will be blown out of the corresponding elongated bar slot 44 and fall into the unqualified material box under the airflow direction. The qualified products detected by the first visual inspection equipment 42 continue to be conveyed forward.

[0045] The feeding conveying device 1 of the present embodiment is a vibrating disc feeding conveying device, which is a prior art product. The material is output in the required state by vibration, and the output end is connected with the input end of the conveyor belt 41 with a conveying groove 11 consistent with the elongated bar slot 44, such as Figure 2As shown, the lower part of the end of the conveyor trough 41 that connects to the input end of the conveyor belt 41 has an overlapping arc-shaped opening 12 for the arc portion of the input end of the conveyor belt 41 to be inserted accordingly, so that the output of the conveyor trough 11 can be connected to the slender bar material trough 44 of the horizontal section of the conveyor belt 41. This can achieve smooth conveying and connection, and prevent situations such as falling or getting stuck. An input guide embedding block 46 is provided above the docking point of the conveyor belt 41 corresponding to the conveyor trough 11 and the slender bar material trough 44 of the horizontal section of the conveyor belt 41. The lower surface of the input guide embedding block 46 is provided with an input guide guide groove 461 corresponding to the conveyor trough 11 and the slender bar material trough 44. This can reliably guide the bar material into the slender bar material trough 44, and it is not easy for conveying to be unsmooth or abnormal at the docking position.

[0046] The turntable detection and rejection device 6, as described above Figure 1 , Figure 4 As shown, the device includes an indexing turntable 61 with independent bar slots 611 evenly distributed around its upper surface, allowing the axial direction of the bar to be radially aligned and embedded into the slots. It also includes at least one set of second vision inspection equipment 62, second rejection and discharge device 63, and qualified discharge device 64, all located at a fixed workstation. When the indexing turntable 61 rotates, each independent bar slot 611 passes sequentially through the output end of the feeding device 5, the second vision inspection equipment 62, the second rejection and discharge device 63, and the qualified discharge device 64, and this rotation is repeated. In this embodiment, since it is used for detecting surface defects of bar stock, the structure of the indexing turntable 61 is different from that of the indexing turntable in other existing product inspections. In addition to carrying the bar stock one by one and rotating in a cycle, the indexing turntable here also needs to roll the bar stock so that different surface sections are upward for image capture and analysis. Therefore, this embodiment discloses that the indexing turntable 61 includes a fixed plate 612 fixedly mounted on the base, a turntable drive motor assembly 613 mounted on the base below the fixed plate 612, and a rotating plate 614 mounted on the base, corresponding to the center of the fixed plate 612 and corresponding to the upper surface of the fixed plate 612. The specific structure is as follows: the fixed disk 612 is provided with a receiving section ring 6121; the rotating disk 614 includes a bar stock groove disk 6141 and a guide ring 6142; the bar stock groove disk 6141 includes a central section 6143 and a bar stock groove section ring 6144 corresponding to the upper surface of the receiving section ring 6121. It should be noted that the bar stock groove section ring 6144 corresponds to the upper surface of the receiving section ring 6121, but there is no fixed contact connection between them, and there should be no gap between them that would allow the bar stock to be embedded. Therefore, they are a close but not connected structure. The central section 6143 is connected to the turntable drive motor assembly 613 to drive rotation. The independent bar stock groove 611 is opened on the bar stock groove section ring 6144 and extends vertically through the bar stock groove disk 6141 and extends outwardly through the outer circumference of the bar stock groove disk 6141. Figure 4The outer periphery of the bar groove section ring 6144 is in a toothed structure, the outer periphery of the bar groove disc 6141 is formed with a connecting edge 6145 protruding from the outer periphery surface of the receiving section ring 6121, one side of the inner ring of the material guiding ring 6142 is connected to the bar groove disc 6141 through the connecting edge 6145 so as to rotate with the bar groove disc 6141, and is not affected by the fixed disc, the material guiding ring 6142 is provided with an independent discharge hole 6146 penetrating the inner and outer ring side walls, so that the bar in the independent bar groove 611 can smoothly pass through the independent discharge hole 6146 from the outer end of the independent bar groove 611 and be discharged, and is not affected by the fixed disc, in the embodiment, the material guiding ring 6142 is composed of two independent ring bodies clamping the connecting edge 6145 to be fixed on the bar groove disc 6141 so as to rotate with the bar groove disc 6141, in order to make the rotation of the bar groove disc 6141 and the material guiding ring 6142 stable, the outer periphery of the fixed disc 612 is provided with a rotating support guide wheel structure 6122 corresponding to the surface of the material guiding ring 6142, and the rotating support guide wheel structure 6122 includes a guide wheel arranged on the fixed disc 612 corresponding to the upper surface of the material guiding ring 6142 and a ball arranged on the fixed disc 612 corresponding to the lower surface of the material guiding ring 6142.

[0047] Through the structure of the indexing turntable 61, since the receiving section ring 6121 is not rotatable and the bar groove section ring 6144 is rotatable, when the rotating disc 614 rotates, the bar embedded in the independent bar groove 611 moves on the fixed disc 612 with the rotation of the bar groove disc 6141, and since the receiving section ring 6121 is not rotatable, friction resistance is formed, which is converted to the bar in the independent bar groove 611, so that the bar rolls, that is, the bar rolls to move on the fixed disc 612, so that when passing through the second visual detection equipment 62 (here, the second visual detection equipment 62 can be continuously provided with multiple groups, and here, two groups are continuously provided), all the outer surfaces of the bar can be continuously photographed, so that the equipment of the application can achieve the surface detection purpose effect.

[0048] The structure of the second removing and discharging device 63 in the embodiment is that the fixed frame is arranged on the outer periphery of the fixed disc 612 and has a waste discharge hole 631 which can sequentially correspond to each independent bar groove 611 and independent discharge hole 6146, and the waste blowing mechanism 632 which is fixedly arranged on the base and has an elongated air outlet 633 corresponding to the entering end of the waste discharge hole 631.

[0049] The qualified feeding device 64 in this embodiment has the following structure: it includes a qualified discharge hole 641 fixedly mounted on the outer periphery of the fixed plate 612 and having a qualified discharge hole 641 that can sequentially connect to each independent bar material groove 611 and an independent discharge hole 6146; a qualified air blowing mechanism 642 fixedly mounted on the machine base and having an elongated air nozzle 643 corresponding to the inlet end of the qualified discharge hole 641; and a feeding inlet end of the feeding and boxing device 3, with one end connected to the discharge end of the qualified discharge hole 641 and the other end corresponding to the feeding inlet end of the feeding and boxing device 3. The discharge chute 644 is designed to prevent the bar stock from turning around during the discharge process. As shown in the figure, the chute is made of a round tube, which prevents the bar stock from turning around during the internal sliding process. The discharge chute 644 is located at the other end of the feeding inlet of the feeding and boxing device 3 to prevent the bar stock from turning around during the discharge process. That is, the lower end of the pipe is positioned so that the orientation of the bar stock will not change when it enters the feeding and boxing device 3 after discharge. In this embodiment, as shown in the figure, the qualified feeding device 64 is equipped with two sets of feeding and boxing devices. These devices are used to confirm the orientation of the bars in the independent bar troughs 611 after testing. The bars are discharged from different qualified feeding devices 64 and boxed, so that all the bars in the box have the same orientation. Thus, the feeding and boxing device 3 is equipped with two sets of feeding and boxing devices for bars with different orientations, corresponding to the qualified feeding device 64. There are other structures that can achieve this orientation screening, feeding, and boxing. For example, the qualified feeding device is a structure with double discharge slides. The slide inlet of the double discharge slides is equipped with a controllable discharge guide structure (this structure is not shown in the figure).

[0050] After the above-mentioned structure is inspected by the second vision inspection device 62, the bar stock with surface defects is blown out of the independent bar stock groove 611 by the waste blowing mechanism 632 when it reaches the second rejection and discharge device 63 as the rotating disk 614 rotates. It is discharged through the waste discharge hole 631. The bar stock with no surface defects is discharged from the qualified feeding device 64. The bar stock with the orientation screening is blown out of the independent bar stock groove 611 by the qualified blowing mechanism 642 when it reaches the qualified feeding device 64 of the corresponding orientation as the rotating disk 614 rotates. It is discharged through the qualified discharge hole 641 to the corresponding feeding and boxing device 3.

[0051] like Figure 3 As shown, in this embodiment, the input end of the fabric feeding device 5 corresponds to the output end of the conveyor belt detection and rejection device 4, and its output end also corresponds to the turntable detection and rejection device 6. Its structure allows for the feeding of fabric bars one by one into the turntable detection and rejection device 6 (specifically, into the independent bar slots 611 on the turntable detection and rejection device 6 described below) for fabric feeding. For example... Figure 1 and Figure 3As shown, the distributing device 5 includes a distributing hopper 51, a distributing wheel 52, a distributing baffle 53, a distributing drive motor 54 and a distributing inlet nozzle 55. The distributing hopper 51 includes a closed connecting side wall plate 511 and an inclined bottom plate 512 connected to the lower edge of the side wall plate 511. The inclined bottom plate 512 forms a flat distributing nozzle 513 corresponding to each independent bar groove 511 on the side of the lower edge of the inclined bottom plate 512 and the opposite side wall plate 511. The flat distributing nozzle 513 can only drop one bar at a time. The length direction of the flat distributing nozzle 513 is consistent with the length direction of the independent bar groove 611, and the two ends of the flat distributing nozzle 513 correspond to the two ends of the independent bar groove 611, so that the whole bar can be smoothly embedded in the independent bar groove 611. The outer periphery of the distributing wheel 52 is uniformly spaced with independent distributing grooves 521 consistent with the axis direction of the distributing wheel 52. The distributing wheel 52 is rotatably arranged in the distributing hopper 51 and is arranged in the inner side of the lower edge of the inclined bottom plate 512 (the inner side can ensure that the bar does not pass through the gap without being embedded in the independent distributing groove 521). The length direction of the independent distributing groove 521 is consistent with the length direction of the flat distributing nozzle 513, so that the bar can be correspondingly arranged in the independent distributing groove 521 while maintaining the required orientation. The wheel shaft of the distributing wheel 52 is connected to the output end of the distributing drive motor 54, and the distributing wheel 52 rotates at a set speed. The distributing baffle 53 is arranged in the distributing hopper 51 and is spaced apart from the lower edge of the inclined bottom plate 512 to form a discharging gap 531 for passing one bar at a time. The distributing wheel 52 corresponds to the flat distributing nozzle 513 and the distributing baffle 53, so that the distributing baffle 53 can facilitate the orderly and reliable distribution of the distributing wheel 52. The distributing inlet nozzle 55 includes an inlet entry end 551 and an inlet exit end 552. The inlet exit end 552 corresponds to the upper side of the inclined high part of the inclined bottom plate 512 in the distributing hopper 51 and is arranged at an angle so that the length direction of the bar tends to be parallel to the length direction of the discharging gap 531. As shown, the bar does not appear perpendicular to the length direction of the discharging gap 531 after being discharged from the inlet exit end 552, so that the subsequent sliding distribution can be ensured. The inlet entry end 551 to the inlet exit end 552 is arranged in a sliding structure for feeding into the distributing hopper 51. Through the above structure of the distributing device 5, the bars from the feeding and conveying device 1 can be orderly and sequentially distributed into the independent bar grooves 611 on the rotating disc 614.

[0052] Finally, the discharging and boxing device 3 in the embodiment discloses a structure that can achieve the same orientation, reduce collision and friction, and orderly arrange the boxes. The structure also needs to prevent the bar from turning around during the discharging process and to have an orderly arrangement structure. The disclosed structure is as follows: Figure 5 andFigure 6 As shown, the blanking and boxing device 3 comprises a blanking hopper 31, a baffle mechanism 32, a linear motion module 33, a lifting and tilting mechanism 34 and a loading box 35. The linear motion module 33 is fixedly arranged on a machine base. The blanking hopper 31 is arranged on the linear motion module 33 through a mounting frame 311 and is driven by the linear motion module 33 to move linearly. The lower end of the blanking hopper 31 is a flat downwardly extending blanking nozzle 312, which is sized to be embedded in the loading box 35.
