Description

Technical Field

[0001] This invention relates to the field of laser coding quality inspection technology, specifically to an integrated machine for automatic coding visual inspection and automatic bag loading of vertical flexible packaging bags. Background Technology

[0002] Stand-up flexible packaging bags (also called squeeze bags) are commonly used for packaging food products such as ketchup, salad dressing, and milk, as well as daily chemical products such as shampoo, shower gel, and cosmetics. Before filling, the empty bags need to be laser-coded or inkjet-coded. After coding or inkjet-coding, the bags are filled directly. The filled bags are then manually checked one by one for the correctness and clarity of the codes, which is labor-intensive and prone to errors.

[0003] In order to improve the detection efficiency, some factories use automatic coding visual inspection equipment for vertical flexible packaging bags. For example, the patent number published on the China Patent Network is 201910480055.X, and the patent name is: Automatic coding visual inspection and automatic bag feeding machine for vertical flexible packaging bags. It solves the technical problem of automatic control of the entire process from coding to code quality inspection, sorting of bags with unqualified codes, and connecting with the filling machine to feed bags. The corner angle of the bag outlet (8) on the bag feeding frame (2) is consistent with the rotation tangent direction of the turntable (9). The corner position coincides with the tooth height convex edge of the groove position of the turntable (9). A circular turntable (9) is designed, and 8 grooves are equally divided at 45° on the turntable (9). Each groove has a tooth height convex edge on the other side. The toothed protrusion of the turntable (9) slot is engaged in the upper position of the bag nozzle (1-1). The guide positioning plate (11) and the guard rod (12) limit the vertical soft packaging bag (1). The rejection device (15) rejects the defective products. The qualified bags are pressed into the slot of the turntable (9) by the guide plate (16). The bag receiving frame (20) is controlled by the PLC to push the bag with the cylinder and is connected to the filling machine.

[0004] However, the material feeding method of this vision inspection and automatic bag feeding integrated machine is relatively simple. It mainly uses a cylinder to squeeze the packaging for feeding. When the packaging is subjected to excessive pressure, it is easy for the packaging to pile up on the guide rail surface, which affects the packaging feeding effect.

[0005] Therefore, it is necessary to design and modify the integrated machine for automatic coding, visual inspection, and automatic bag feeding of upright flexible packaging bags. Summary of the Invention

[0012] The feeding guide rail is equipped with a positioning structure inside;

[0013] The top of the feeding guide rail is provided with a transmission structure located inside the positioning structure.

[0014] The positioning structure includes pressure plates disposed on both sides inside the feeding guide rail. The pressure plates are movably connected to the feeding guide rail via pins. The side of the pressure plate away from the feeding guide rail extends to the top of the packaging bag. A sleeve plate is fixedly connected to the top of the pressure plate. The transmission structure can drive the sleeve plate to swing.

[0015] In a preferred embodiment of the present invention, the transmission structure includes a vertical plate fixedly connected to the right side of the unloading guide rail. A screw is movably connected to the left side of the vertical plate via a bearing. The screw is located at the top of the unloading guide rail. A threaded sleeve is threaded onto the surface of the screw. The threaded sleeve is located inside a sleeve plate. A sliding rod is fixedly connected to both the front and back of the threaded sleeve. The side of the sliding rod away from the threaded sleeve extends into the interior of the sleeve plate. The sleeve plate and the sliding rod are slidably connected. A drive motor is fixedly connected to the right side of the vertical plate. The right end of the screw penetrates the vertical plate and extends to the right side of the vertical plate. The right end of the screw is fixedly connected to the output end of the drive motor.

[0016] As a preferred embodiment of the present invention, guide rods are fixedly connected to the front and rear ends of the left side of the upright plate. The guide rods are located on both sides of the screw rod. The end of the guide rod away from the upright plate passes through the screw sleeve and extends to the left side of the screw sleeve. The screw sleeve and the guide rod are slidably connected.

[0017] In a preferred embodiment of the present invention, a support plate is fixedly connected to the top of the upright plate, and the side of the support plate away from the upright plate is sleeved on the surface of the screw rod. The screw rod and the support plate are movably connected, the support plate is sleeved on the surface of the guide rod, the support plate is fixedly connected to the guide rod, and the screw sleeve is located inside the support plate.

[0018] As a preferred embodiment of the present invention, the surface of the sleeve plate is fixedly connected with a reinforcing rib, the side of the reinforcing rib away from the sleeve plate extends to the top of the pressure plate, and the pressure plate is fixedly connected to the reinforcing rib.

[0019] As a preferred embodiment of the present invention, a rubber pad is fixedly connected to the bottom of the pressure plate, the rubber pad is located at the top of the packaging bag, the side of the rubber pad away from the pressure plate is in contact with the top of the packaging bag, and the rubber pad is elastic.

[0020] As a preferred embodiment of the present invention, the screw has a threaded connection to a transmission block, the transmission block has a spring plate fixedly connected to its surface, the side of the spring plate away from the transmission block is in contact with the surface of the packaging bag, the spring plate is elastic, and the end of the guide rod away from the upright plate passes through the transmission block and extends to the left side of the transmission block.

[0021] In a preferred embodiment of the present invention, the left end of the guide rod is fixedly connected to a limiting plate, and the left end of the screw extends into the interior of the limiting plate and is movably connected to the limiting plate.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. This invention uses a transmission structure to compress the packaging bag, causing it to swing around a pin. When the rubber pad at the bottom of the pressure plate contacts the surface of the packaging bag, it achieves the effect of squeezing and positioning the packaging bag. At the same time, the gap between the pressure plate and the feeding guide rail facilitates the movement of the packaging bag. This invention improves the feeding method of the integrated vision inspection and automatic bag feeding machine. It uses an auxiliary cylinder to squeeze the packaging bag for feeding, avoiding the accumulation of packaging on the guide rail surface when subjected to excessive compression, thus ensuring the packaging feeding effect.

[0024] 2. This invention uses a drive motor to drive a screw to rotate. The screw uses its thread to push the screw sleeve to move horizontally. During the movement of the screw sleeve, the sliding rod slides inside the sleeve plate. The sleeve plate is squeezed and causes the pressure plate to swing around the pin axis. This can simultaneously push the pressure plates on both sides to swing, which can effectively adjust the squeezing intensity of the pressure plates. Moreover, the screw has high transmission efficiency, which can prevent the screw sleeve from rotating and slipping, further ensuring transmission stability.

[0025] 3. By setting a guide rod, the present invention can limit the screw sleeve, prevent the screw sleeve from tilting during movement, and increase the contact area between the screw sleeve and the upright plate.

[0026] 4. By setting a support plate, the present invention can support the screw, which can improve the contact area and connection stability between the screw and the vertical plate. At the same time, it can reduce the contact area between the transmission structure and the external environment, improve the operational safety of the transmission structure, and prevent users from being injured by the structure during the movement process.

[0027] 5. By setting reinforcing ribs, the present invention can improve the connection strength between the sleeve plate and the pressure plate, and prevent the connection between the two from breaking due to excessive load.

[0028] 6. By setting up a rubber pad, the present invention can protect the pressure plate, reduce the pressure of the pressure plate, and prevent the packaging bag from being excessively squeezed. Moreover, the elastic rubber pad has a high overall friction, which prevents the packaging bag from sliding or shifting.

[0029] 7. This invention uses a screw to carry a transmission block to move synchronously. The transmission block uses a spring plate to squeeze the packaging bag, causing it to slide and move inside the feeding guide rail, and forcing it to move away from the machine body. This can reduce the travel of the cylinder inside the machine body by using the power of the screw, and can also prevent the packaging bag from being over-compressed.

[0030] 8. By setting a limiting plate, the present invention can limit the transmission block, avoid excessive movement of the transmission block, prevent the transmission block from losing contact with the screw, and effectively connect the screw and the guide rod. Attached Figure Description

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] like Figures 1 to 6 As shown, the present invention provides an integrated machine for automatic coding, visual inspection and automatic bag loading of vertical flexible packaging bags, including a machine body 1;

[0040] The feeding guide rail 2 is fixedly connected to the front of the machine body 1;

[0041] The feeding guide rail 3 is located on the right side of the machine body 1;

[0042] The packaging bag 4 is placed inside the feeding guide rail 3;

[0047] refer to Figure 4 The transmission structure 7 includes a vertical plate 10 fixedly connected to the right side of the feeding guide rail 3. A screw 11 is movably connected to the left side of the vertical plate 10 via a bearing. The screw 11 is located at the top of the feeding guide rail 3. A screw sleeve 12 is threadedly connected to the surface of the screw 11. The screw sleeve 12 is located inside the sleeve plate 9.

The right end of the screw 11 passes through the vertical plate 10 and extends to the right side of the vertical plate 10. The right end of the screw 11 is fixedly connected to the output end of the drive motor 14.

[0048] As a technical optimization of the present invention, the screw 11 is driven to rotate by the transmission motor 14. The screw 11 pushes the screw sleeve 12 to move horizontally by means of the thread. During the movement of the screw sleeve 12, the slide rod 13 is driven to slide inside the sleeve plate 9. The sleeve plate 9 is squeezed and drives the pressure plate 8 to swing around the pin shaft. It can simultaneously push the pressure plates 8 on both sides to swing, and can effectively adjust the squeezing intensity of the pressure plate 8. Moreover, the screw 11 has high transmission efficiency, which can prevent the screw sleeve 12 from rotating and slipping, and further ensure transmission stability.

[0049] refer to Figure 4 Guide rods 15 are fixedly connected to the front and rear ends of the left side of the upright plate 10. The guide rods 15 are located on both sides of the screw rod 11. The end of the guide rod 15 away from the upright plate 10 passes through the screw sleeve 12 and extends to the left side of the screw sleeve 12.

[0050] As a technical optimization of the present invention, by setting the guide rod 15, the screw sleeve 12 can be limited, so as to avoid the screw sleeve 12 tilting during the movement.

The side of the support plate 16 away from the upright plate 10 is sleeved on the surface of the screw 11. The screw 11 and the support plate 16 are movably connected. The support plate 16 is sleeved on the surface of the guide rod 15. The support plate 16 and the guide rod 15 are fixedly connected. The screw sleeve 12 is located inside the support plate 16.

[0052] As a technical optimization of the present invention, by setting the support plate 16, the screw 11 can be supported, which can improve the contact area and connection stability between the screw 11 and the upright plate 10.

[0053] refer to Figure 5-6 A reinforcing rib 17 is fixedly connected to the surface of the sleeve plate 9. The side of the reinforcing rib 17 away from the sleeve plate 9 extends to the top of the pressure plate 8, and the pressure plate 8 is fixedly connected to the reinforcing rib 17.

[0054] As a technical optimization of the present invention, by setting the reinforcing rib 17, the connection strength between the sleeve plate 9 and the pressure plate 8 can be improved, and the connection between the two can be prevented from breaking due to excessive load.

[0055] refer to Figure 5 A rubber pad 18 is fixedly connected to the bottom of the pressure plate 8. The rubber pad 18 is located on the top of the packaging bag 4. The side of the rubber pad 18 away from the pressure plate 8 contacts the top of the packaging bag 4. The rubber pad 18 is elastic.

[0056] As a technical optimization of the present invention, by setting the rubber pad 18, the pressure plate 8 can be protected, the pressure of the pressure plate 8 can be reduced, and the packaging bag 4 can be prevented from being excessively squeezed.

[0057] refer to Figure 4 The screw 11 is threadedly connected to a transmission block 19, and a spring plate 20 is fixedly connected to the surface of the transmission block 19. The side of the spring plate 20 away from the transmission block 19 is in contact with the surface of the packaging bag 4. The spring plate 20 is elastic. The end of the guide rod 15 away from the upright plate 10 passes through the transmission block 19 and extends to the left side of the transmission block 19.

[0058] As a technical optimization of the present invention, the screw 11 carries the transmission block 19 to move synchronously by means of the thread. The transmission block 19 uses the spring plate 20 to squeeze the packaging bag 4, causing it to slide and move inside the feeding guide rail 3, and forcing it to move away from the machine body 1. This can reduce the movement stroke of the cylinder inside the machine body 1 by means of the power of the screw 11, and can also prevent the packaging bag 4 from being over-compressed.

[0059] refer to Figure 3 The left end of the guide rod 15 is fixedly connected to the limiting plate 21, and the left end of the screw 11 extends into the interior of the limiting plate 21 and is movably connected to the limiting plate 21.

[0060] As a technical optimization of the present invention, by setting a limiting plate 21, the transmission block 19 can be limited to avoid excessive movement of the transmission block 19.

[0061] The working principle and usage process of this invention are as follows: During use, the packaging bag 4 is conveyed to the inside of the rotating wheel 5 via the feeding guide rail 2. As the rotating wheel 5 carries the packaging bag 4, it can be inspected and processed by the machine body 1. After inspection, the packaging bag 4 is pushed by the conveying cylinder inside the machine body 1 to the inside of the unloading guide rail 3. Simultaneously, the drive motor 14 drives the screw 11 to rotate. The screw 11 uses its thread to push the screw sleeve 12 to move horizontally. During the movement of the screw sleeve 12, it causes the sliding rod 13 to slide inside the sleeve plate 9. The sleeve plate 9 is compressed, causing the pressure plate 8 to swing around the pin axis. When the rubber pad 18 at the bottom of the pressure plate 8 contacts the surface of the packaging bag 4, it achieves the effect of squeezing and positioning the packaging bag 4. When the screw 11 flips and causes the pressure plate 8 to disengage from the packaging bag 4... The screw 11 can carry the transmission block 19 to move synchronously using the thread. The transmission block 19 uses the spring plate 20 to squeeze the packaging bag 4, causing it to slide and move inside the feeding guide rail 3, and forcing it to move away from the machine body 1. The transmission block (19) resets to the left during the screw (11) rotating forward and being squeezed by the pressure plate (8). During the reset process, the spring plate (20) contacts the conveying cylinder of the machine body (1) used to convey the packaging bag (4) and uses the squeezing force of the conveying cylinder to push the spring plate (20) to deform. When the spring plate (20) swings to the left side of the conveyed packaging bag (4), the conveying cylinder inside the machine body (1) resets. At the same time, the drive motor (14) flips and uses the spring plate (20) to cycle the above steps to push the packaging bag (4) to move further.

[0062] In summary, this vertical flexible packaging bag automatic coding visual inspection and automatic bag loading integrated machine uses the transmission structure 7 to squeeze and make it swing around the pin shaft. When the rubber pad 18 at the bottom of the pressure plate 8 contacts the surface of the packaging bag 4, it achieves the effect of squeezing and positioning the packaging bag 4. At the same time, the gap between the pressure plate 8 and the feeding guide rail 3 facilitates the movement of the packaging bag 4. This invention can improve the feeding method of the visual inspection and automatic bag loading integrated machine, and use the auxiliary cylinder to squeeze the packaging for feeding operation, avoiding the phenomenon of packaging piling up on the guide rail surface when subjected to excessive compression, thus ensuring the packaging feeding effect.
