Description

Technical Field

[0001] This invention relates to the field of packaging bag rejection technology, and more particularly to a single-station, multi-path material rejection method. Background Technology

[0002] In the packaging bag printing industry, the requirements for printing quality are becoming increasingly stringent. Therefore, the precision of quality inspection before packaging bags are put into use also increases. It is necessary to quickly reject defective bags after identification to prevent them from entering subsequent workflows. To improve rejection efficiency, machine rejection is usually used instead of manual rejection. However, when dealing with multiple packaging bags, rejecting only defective bags from one or a few channels will affect the counting of bags at the unloading end, increasing the difficulty of counting bundles (each bundle should contain the same number of good bags), and adding extra workload for recounting. Dividing the process into multiple stations to separately handle good and defective bags from the same batch would increase the overall size and manufacturing cost of the equipment, and also increase operational difficulty.

[0003] Therefore, there is an urgent need for a single-station, multi-path material rejection method to solve the above-mentioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to provide a single-station, multi-path material rejection method that can separate good and defective products at the same station without affecting the bundled counting of good products at the unloading end, thereby improving operational efficiency, requiring no manual intervention, and facilitating automated packaging.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A single-station, multi-path material rejection method includes:

[0007] S100: Identify whether the incoming workpiece is a good product or a defective product through the identification mechanism;

[0008] S200: The feeding mechanism feeds the workpieces along the first direction, and the separating mechanism divides the multiple workpieces into multiple paths along the second direction.

[0009] S300: When all the workpieces in multiple channels are good products, the diversion mechanism is used to transfer the multiple good products to the unloading mechanism. The unloading mechanism delivers all the good products to the unloading end and counts them one by one.

[0010] S400. When there are defective products among the multiple workpieces, the diversion mechanism no longer transports the workpieces to the unloading mechanism, and the diversion mechanism is configured to transfer good products and defective products to different workstations respectively, so that when defective products are removed at the same workstation, good products of the same batch will not enter the unloading end.

[0011] Preferably, S300 includes:

[0012] S310. The diversion mechanism is a reversing mechanism. The reversing mechanism can rotate to a horizontal angle and connect with the feeding mechanism and the unloading mechanism so as to convey multiple good products along the first direction.

[0013] Preferably, S300 further includes:

[0014] S320. The diversion mechanism is a suction mechanism, which can adsorb multiple good products and transport them along the first direction to the unloading mechanism.

[0015] Preferably, S400 includes:

[0016] S410, the feeding mechanism tilts upward, and the reversing mechanism corresponding to the defective product path is in a horizontal position and forms a rejection gap with the feeding mechanism, so that the defective product can fall from the rejection gap to the conveying mechanism below.

[0017] Preferably, the S400 further includes:

[0018] S420, the reversing mechanism corresponding to the good product path rotates and tilts up, and docks with the recycling bin above the unloading mechanism, so that good products of the same batch can be conveyed into the recycling bin.

[0019] Preferably, in S410, the defective product can slide down the guide plate at the bottom of the feeding mechanism to the conveying mechanism.

[0020] Preferably, the S400 further includes:

[0021] S430. When the suction mechanism adsorbs the defective product and brings it above the first conveying position of the conveying mechanism, the suction force is released so that the defective product falls onto the first conveying position.

[0022] Preferably, the S400 further includes:

[0023] S440. When the suction mechanism adsorbs good products and brings them above the second conveying position of the conveying mechanism, the suction force is released so that the good products of the same batch fall onto the second conveying position.

[0024] Preferably, S200 includes:

[0025] S210. Adjust the extension length of the feeding mechanism along the first direction and connect it with the external material receiving structure.

[0026] Preferably, S200 further includes:

[0027] S220. Adjust the spacing between two adjacent partitions in the separating mechanism along the second direction.

[0028] The beneficial effects of this invention are:

[0029] This invention discloses a single-station, multi-path material rejection method. Specifically, it includes the following steps: S100, identifying whether incoming workpieces are good or defective using an identification mechanism; S200, feeding workpieces along a first direction using a feeding mechanism, and separating multiple workpieces into multiple paths along a second direction using a separating mechanism; S300, when all workpieces in multiple paths are good, using a diversion mechanism to transfer the good workpieces to an unloading mechanism, which then transports all good workpieces to the unloading end and counts them path by path; S400, when defective workpieces are present in multiple paths, the diversion mechanism no longer transports workpieces to the unloading mechanism, and the diversion mechanism is configured to transfer good and defective workpieces to different stations respectively, so that when defective workpieces are rejected at the same station, good workpieces from the same batch will not enter the unloading end. This method can separate good and defective workpieces at the same station without affecting the bundled counting of good workpieces at the unloading end.

[0030] This method enables the separation mechanism to process incoming workpieces at the same workstation. When all workpieces are good, the separation mechanism can transfer multiple good workpieces from the loading mechanism to the unloading mechanism along the original path, ensuring that the number of good workpieces in each unloading end is the same, thus facilitating automatic counting and packaging. When there are defective workpieces in a batch of incoming materials, the separation mechanism can separate the good and defective workpieces at its own position. While removing defective workpieces, it ensures that the good workpieces in this batch will not be mixed into the unloading end, thereby avoiding affecting the bundle counting at the unloading end and thus greatly improving operational efficiency.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used merely for distinction in description and have no special meaning.

[0050] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0051] like Figures 1 to 6 As shown, the present invention provides a single-station, multi-path material rejection method; the method specifically includes the following steps:

[0052] S100: Identify whether the incoming workpiece 80 is a good product or a defective product through the identification mechanism;

[0053] S200: The feeding mechanism 10 feeds the workpieces along the first direction, and the separating mechanism 20 separates the multiple workpieces 80 into multiple paths along the second direction.

[0054] S300: When all the workpieces 80 are good, the diversion mechanism is used to transfer the good workpieces to the unloading mechanism 40. The unloading mechanism 40 will transport all the good workpieces to the unloading end and count them one by one.

[0055] S400 When there are defective products in the multi-channel workpiece 80, the diversion mechanism no longer transports the workpiece 80 to the unloading mechanism 40, and the diversion mechanism is configured to transfer good products and defective products to different workstations respectively, so that when defective products are removed at the same workstation, good products of the same batch will not enter the unloading end.

[0056] This method enables the separation mechanism to process incoming workpieces 80 at the same workstation. When all workpieces 80 are good products, the separation mechanism can transfer multiple good products from the loading mechanism 10 to the unloading mechanism 40 along the original path, ensuring that the number of good products in each unloading end is the same, thus facilitating automatic counting and packaging. When there are defective products in a batch of incoming materials, the separation mechanism can separate the good products from the defective products at its own position, and while removing the defective products, it ensures that the good products in this batch will not be mixed into the unloading end, thereby avoiding affecting the bundle counting at the unloading end and thus greatly improving the operating efficiency.

[0057] Example 1

[0058] like Figures 2-4 As shown, step S300 includes S310, that is, the diversion mechanism is a reversing mechanism 30. The reversing mechanism 30 can rotate to a horizontal angle and connect with the feeding mechanism 10 and the unloading mechanism 40 so as to convey multiple good products along the first direction. Specifically, the reversing mechanism 30 includes a reversing frame 31, a lifting member 32, a reversing roller 33 and a power assembly. The reversing frame 31 is set on the equipment body, the lifting member 32 is installed on the reversing frame 31, the reversing roller 33 is installed on the equipment body and is connected to the power assembly for transmission, and the output end of the lifting member 32 is connected to the bottom of the power assembly so as to drive the power assembly to rotate. In this configuration, the reversing frame 31 is installed on the equipment body, which improves the ease of installation and stability. It also facilitates the fixing of the lifting component 32. The output end of the lifting component 32 can extend and retract, which can automatically adjust the angle of the power component. Thus, when all incoming materials are good products, the lifting component 32 can drive the power component to a horizontal angle and connect the loading mechanism 10 and the unloading mechanism 40, thereby conveying good products along the first direction, ensuring conveying efficiency and improving work efficiency.

[0059] Step S400 includes S410, where, when a defective product is present in the incoming workpiece 80, the unloading mechanism 40 tilts upward, and the reversing mechanism 30 corresponding to the defective product path is in a horizontal position, forming a rejection gap with the unloading mechanism 40, so that the defective product can fall through the rejection gap to the conveying mechanism 50 below. This step allows a rejection gap to be naturally formed between the unloading mechanism 40 and the reversing mechanism 30, thereby enabling the smooth and efficient rejection of defective products.

[0060] To ensure that good and defective products do not fall onto the conveyor mechanism 50 simultaneously, step S400 also includes S420, where the reversing mechanism 30 corresponding to the good product path rotates and tilts upwards, docking with the recycling bin 60 above the unloading mechanism 40, so that good products of the same batch can be conveyed into the recycling bin 60. The specific structure is as follows: Figures 2-4As shown, the power assembly includes a reversing belt 34, a reversing plate 35, and a driven pulley 36. The reversing roller 33 and the driven pulley 36 respectively engage to tension the reversing belt 34. The reversing plate 35 is located between the reversing roller 33 and the driven pulley 36, with one end pivotally connected to the reversing frame 31 and the other end pivotally connected to the driven pulley 36. The output end of the lifting member 32 is connected to the bottom of the reversing plate 35. When the reversing roller 33 rotates, it can drive the reversing belt 34 to rotate. The structure of the driven pulley 36 being pivotally connected to the reversing plate 35 ensures the smooth operation of the reversing belt 34, thereby ensuring that the reversing belt 34 can generate sufficient conveying force for the workpiece 80 and avoid the workpiece 80 from stopping. Furthermore, the reversing plate 35 is pivotally connected to the reversing frame 31. Therefore, when it is necessary to transport the workpiece 80 to the recovery bin 60, the output end of the lifting member 32 extends vertically, thereby causing the reversing plate 35 to rotate around the pivot position, thus forming an upward posture and docking with the recovery bin 60, realizing reversing collection. When the power component is in a horizontal state, the lifting member 32 can support the reversing plate 35 from the bottom, ensuring the stability of the reversing plate 35.

[0061] In addition, such as Figure 4 As shown, a tensioning roller 37 is also provided between the reversing roller 33 and the driven roller 36. The tensioning roller 37 is connected to the reversing plate 35 via a connecting block 38, and the tensioning roller 37 is pivotally connected to the connecting block 38 to tension the reversing belt 34. In this structure, the tensioning roller 37 can move synchronously with the reversing plate 35, thereby ensuring that the reversing belt 34 can be tensioned no matter which posture the reversing plate 35 rotates to. At the same time, the tensioning roller 37 can rotate relative to the connecting block 38, thus improving the smoothness of the reversing belt 34 during operation and ensuring a good reversing conveying effect.

[0062] To ensure a good rejection effect, in step S410, the defective product can slide down the guide plate 45 at the bottom of the unloading mechanism 40 to the conveying mechanism 50. This method ensures the smoothness and regularity of the defective product's removal from the rejection gap, preventing the workpiece 80 from falling randomly and failing to reach the conveying mechanism 50 smoothly. The specific structure is as follows... Figure 2 and Figure 3As shown, the feeding mechanism 40 includes a drive roller 41, a tension roller 42, a transmission roller 43, and a feeding belt 44. The drive roller 41 and the transmission roller 43 respectively engage to tension the feeding belt 44. Multiple tension rollers 42 are arranged between the drive roller 41 and the transmission roller 43 to tension the feeding belt 44. The guide plate 45 is located below the transmission roller 43. That is, after the drive roller 41 rotates, it can drive the feeding belt 44 to rotate around the transmission roller 43, and the multiple tension rollers 42 can maintain the tension of the feeding belt 44 to prevent slack. The friction force on the surface of the feeding belt 44 drives the good products to the feeding station. The feeding mechanism 40 also includes a cylinder, a rotating shaft, and a drive plate (located inside the equipment body, not shown in the figure). The output end of the cylinder is hinged to one end of the drive plate. The rotating shaft passes through the drive plate and is hinged to the equipment body, and the rotating shaft is hinged to the drive plate. The other end of the drive plate is connected to the transmission roller 43, and the guide plate 45 is connected to the drive plate. In this structure, when the cylinder's output end retracts, the end of the drive plate connected to it moves accordingly, and the drive plate rotates around the shaft. This causes the other end of the drive plate to tilt upwards, thereby causing the transmission roller 43 and guide plate 45 to tilt upwards together, forming a rejection gap with the reversing mechanism 30. Conversely, when the cylinder's output end extends, the drive plate can drive the transmission roller 43 downwards to switch to the conveying state. The overall structure is simple, and installation and use are extremely convenient. Switching between rejection and conveying states can be completed simply by extending and retracting the cylinder, significantly reducing manufacturing and usage costs.

[0063] Example 2

[0064] like Figures 5-6 As shown, step S300 also includes S320, that is, the diversion mechanism is a suction mechanism 70. The suction mechanism 70 can adsorb multiple good products and transport them along the first direction to the unloading mechanism 40. Specifically, the suction mechanism 70 includes a bracket 71, a suction belt 72, a negative pressure body 73, and a drive shaft 74. The bracket 71 is set on the equipment body, the negative pressure body 73 is set on the bracket 71 along the first direction, and the drive shaft 74 is set on the bracket 71 along the second direction. The drive shaft 74 engages with the negative pressure body 73 to tension the suction belt 72. The drive shaft 74 can drive the suction belt 72 to move, and the negative pressure body 73 can generate negative pressure on the lower surface of the suction belt 72 to adsorb the workpiece 80. This configuration is not only simple in structure but also convenient to install. The bracket 71 can ensure the stability of the suction mechanism 70, and the drive shaft 74 can drive the suction belt 72 to move, thereby enabling the adsorption of the workpiece 80 by using negative pressure while simultaneously transporting the workpiece 80 along the first direction.

[0065] Furthermore, step S400 also includes S430, where the suction mechanism 70 adsorbs the defective product, and when the defective product reaches above the first conveying position 51 of the conveying mechanism 50, the suction force is released, allowing the defective product to fall onto the first conveying position 51. This step enables the defective product to fall onto the first conveying position 51 after the suction force is released, thereby conveying the defective product to the defective product recycling station.

[0066] Furthermore, step S400 also includes S440, where the suction mechanism 70 adsorbs good products and, when the good products reach above the second conveying position 52 of the conveying mechanism 50, the suction force is released, allowing the good products of the same batch to fall onto the second conveying position 52. This step, combined with S430, ensures that good and defective products of the same batch are conveyed separately, not only eliminating defective products but also preventing them from mixing with good products. It also ensures that good products within the same batch are not mixed into the counting at the unloading end, guaranteeing convenience for subsequent packaging.

[0067] It should be noted that the suction mechanism 70 has two sets of negative pressure devices, and both sets of negative pressure devices are connected to the negative pressure body 73. However, one set is used to control the falling of defective products, and the other set of negative pressure devices is used to control the falling of good products (in the same batch as the defective products). This ensures that the two do not affect each other, thereby ensuring the accuracy of rejection and ensuring a good rejection effect.

[0068] In addition, the suction mechanism 70 also includes a slide rail 75 and a slider 76. The slide rail 75 is mounted on the bracket 71 and extends along the second direction. One end of the slider 76 is connected to the negative pressure body 73, and the other end slides in engagement with the slide rail 75 to adjust the distance between two adjacent negative pressure bodies 73. This arrangement allows for adjustment of the distance between two adjacent suction mechanisms 70, thereby preventing mutual interference when multiple suction mechanisms 70 adsorb workpieces 80, ensuring a good rejection effect. Furthermore, the sliding engagement of the slide rail 75 and the slider 76 also ensures smooth sliding and a good user experience.

[0069] Preferably, the suction mechanism 70 further includes multiple tensioning shafts 77, all of which are arranged along the second direction, and the suction belt 72 passes around the multiple tensioning shafts 77. This arrangement can significantly improve the tensioning effect of the suction belt 72, thereby ensuring that the workpiece 80 will not become loose during transport and guaranteeing good material handling and rejection results.

[0070] Furthermore, a pulley 78 is provided at the end of the negative pressure body 73, and the pulley 78 is pivotally connected to the negative pressure body 73, with the suction belt 72 passing around multiple pulleys 78. By providing pulleys 78, not only can the suction belt 72 be further tensioned, but the pulleys 78 are also rotatably connected to the negative pressure body 73, reducing the movement resistance of the suction belt 72, ensuring the smooth operation of the suction belt 72, and thus improving the conveying efficiency.

[0071] Based on Embodiments 1 and 2, step S200 includes S210, which involves adjusting the extension length of the feeding mechanism 10 along the first direction and docking it with the external material receiving structure. Some material receiving structures are large in volume and inconvenient to move. This step facilitates the feeding and docking with the structure, thereby improving work efficiency and increasing the number of workpieces 80 that the feeding mechanism 10 can accommodate.

[0072] The specific structure is as follows: Figure 2 , Figure 3 as well as Figure 5 As shown, the feeding mechanism 10 includes a drive roller 11, a driven roller 12, a tension roller 13, and a feeding belt 14. The drive roller 11 and the driven roller 12 respectively engage with the feeding belt 14. Multiple tension rollers 13 are arranged between the drive roller 11 and the driven roller 12 to tension the feeding belt 14, and one tension roller 13 is at the same height as the driven roller 12. That is, after the drive roller 11 rotates, it can drive the feeding belt 14 to rotate around the driven roller 12, and the multiple tension rollers 13 can maintain the tension of the feeding belt 14, preventing slack. The friction force on the surface of the feeding belt 14 drives the workpiece 80 to move along the first direction. The overall structure is simple, easy to install, and significantly improves feeding efficiency. Furthermore, as... Figure 2 As shown, the feeding mechanism 10 also includes an adjusting plate 15 and a floating roller 16. The adjusting plate 15 is slidably connected to the equipment body. A tension roller 13, at the same height as the driven roller 12, is disposed on the adjusting plate 15. The feeding belt 14 passes around the floating roller 16. The adjusting plate 15 is configured to slide in a first direction, and the floating roller 16 can float in the vertical direction to adjust the preload of the feeding belt 14. Since the workstation where the feeding mechanism 10 receives incoming materials may not be convenient to place the entire device, the horizontal length of the feeding mechanism 10 can be extended by sliding the adjusting plate 15, thereby facilitating docking and significantly improving ease of use.

[0073] It should be noted that a sliding block (not shown in the figure) is provided on the inner side of the equipment body, and a guide rail 17 is provided on the outer side of the adjusting plate 15. The sliding block is slidably connected to the guide rail 17. A floating groove is also provided on the vertical side of the equipment body. The two ends of the floating roller 16 are set in the floating groove. When feeding is required, the adjusting plate 15 can be fixed on both sides by the fixing block to prevent it from sliding. When it is necessary to extend the length of the feeding end, the fixing block can be removed and the adjusting plate 15 can be slid to extend its horizontal feeding section to the preset length. At the same time, the floating roller 16 can float accordingly in the floating groove to adjust the tension of the feeding belt 14. It is necessary to ensure that the feeding belt 14 is always in a taut state, and to avoid it breaking due to excessive tension, thereby ensuring a good feeding effect and improving the convenience of use.

[0074] Furthermore, based on Embodiments 1 and 2, S200 also includes S220, which involves adjusting the spacing between two adjacent partitions 22 in the separating mechanism 20 along the second direction. This method can improve the smoothness and convenience of feeding, avoid the situation where the spacing path is too narrow to allow the workpiece 80 to pass through, and also avoid the situation where the width is too large, resulting in wasted space.

[0075] The specific structure is as follows: Figure 2 and Figure 5 As shown, the separating mechanism 20 includes a separating frame 21 and partitions 22. The separating frame 21 is mounted on the equipment body, and multiple partitions 22 are spaced apart on the equipment body along a second direction. A passage can be formed between two adjacent partitions 22, and the spacing between two adjacent partitions 22 is adjustable. In this structure, the separating frame 21 is mounted on the equipment body, thereby improving the stability and convenience of installing multiple partitions 22. Furthermore, the natural formation of a passage between two adjacent partitions 22 simplifies the overall structure and reduces processing and manufacturing costs. The adjustable spacing between the partitions 22 also increases the applicability of the separating mechanism 20.

[0076] In summary, the single-station multi-path material rejection method provided by this invention can not only separate good and defective products at the same station, but also does not affect the bundled counting of good products at the unloading end, thereby improving operational efficiency, requiring no manual intervention, and facilitating automated packaging.
