Description
Technical Field
[0001] This application relates to the technical field of glass waste and defective product treatment, and in particular to a waste and defective product rejection device for glass production lines. Background Technology
[0002] In glass bottle production lines, waste glass bottles are typically rejected after manual visual inspection or machine vision inspection. Defective products identified through manual visual inspection are usually removed manually, while machine vision inspection often involves controlling robotic arms to pick them up. However, since the robotic arms are usually located downstream of the machine vision inspection process, if the picking and rejection operation is not performed promptly, defective products may be mixed with qualified products. Therefore, further improvements are needed. Utility Model Content
[0003] To improve the rejection effect of defective glass bottles, this application provides a defective product rejection device for glass production lines.
[0004] This application provides a waste and defective product rejection device for a glass production line, which adopts the following technical solution:
[0005] A waste product rejection device for a glass production line is installed on a conveyor frame for conveying glass bottles. The conveyor frame is equipped with a baffle for abutting against the glass bottles. The device includes a support frame mounted on the conveyor frame, a rejection mechanism mounted on the support frame, and a stop bar mounted on the side of the baffle. The side wall of the baffle has a rejection opening. The baffle is equipped with a rotating component for driving the stop bar to rotate and open / close the rejection opening. The rejection mechanism includes a swing arm rotatably connected to the support frame for pushing the waste glass bottles towards the stop bar, and a driving component mounted on the support frame for driving the swing arm to rotate. As the swing arm pushes, the waste glass bottles push against the stop bar to detach from the conveyor frame and fall into the waste recycling line.
[0006] By adopting the above technical solution, when the machine vision system detects a defective product, the corresponding data is transmitted to the host computer. The host computer then sends the corresponding operation command to the controller. The controller activates the drive assembly to rotate the swing arm, which in turn pushes the glass bottle. Under the thrust of the swing arm, the bottle pushes the stop lever to open the rejection port, detaching it from the conveyor and causing it to fall into the waste and defective product recycling line. The swing arm method of detaching the defective glass bottle from the conveyor requires a relatively short operation time, thereby improving the rejection efficiency.
[0007] Preferably, a plurality of baffles are provided at intervals along the length direction of the baffle.
[0008] By adopting the above technical solution, the cost is relatively low compared to that of a robotic arm, and several can be set up to improve the rejection effect of defective products.
[0009] Preferably, there are two baffles, which are respectively disposed on both sides of the glass bottle. The upper end of the swing arm is disposed on the center line of the two baffles, and both baffles are provided with a rejection opening along the axis of the swing arm.
[0010] By adopting the above technical solution, the swing arm can remove defective glass bottles during its back-and-forth swinging process, thereby reducing the time spent on swing arm reset and further accelerating the removal rate of defective products.
[0011] Preferably, the bracket includes a vertical rod disposed on the baffle and a mounting groove disposed on the vertical rod. A rotating plate is fixedly connected to the upper end of the swing arm. A first rotating rod is coaxially inserted through the rotating plate. The rotating plate is built into the mounting groove. The two ends of the first rotating rod are rotatably connected to the two opposite surfaces of the mounting groove. The drive assembly includes a gear ring coaxially sleeved outside the rotating plate, a drive gear meshing with the gear ring, and a drive motor for driving the drive gear to rotate. The drive motor is fixedly connected to the outer side wall of the mounting groove. The output shaft of the drive motor rotatably passes through the mounting groove to be fixedly connected to the drive gear.
[0012] By adopting the above technical solution, the drive motor is started, which sequentially drives the drive gear, gear ring, rotating plate and swing arm to rotate, thereby performing the rejection operation on the glass bottle.
[0013] Preferably, the rotating assembly includes a rotating component that drives the stop lever to rotate and an elastic component disposed on the rotating component, wherein the elastic component normally forces the stop lever to close the rejection port.
[0014] By adopting the above technical solution, the rotating component allows the baffle to rotate when the glass bottle is pushed by the swing arm. After rotating to the corresponding position, the rejection port is opened so that the defective products fall into the waste recycling line for recycling. After falling, the baffle closes the rejection port under the elastic force of the elastic component.
[0015] Preferably, there are two baffles respectively located on both sides of the glass bottle. The two baffles are a first baffle and a second baffle. The rejection port is located on the first baffle, and the waste recycling line is located on the side of the first baffle away from the second baffle. The rejection mechanism also includes a push plate rotatably connected to the second baffle, and the swing arm is used to push the push plate to move towards the baffle bar.
[0016] By adopting the above technical solution, in the production process, since sometimes the glass bottles produced in the same batch may have defects, the effect of removing such a large number of defective products one by one by the swing arm is relatively poor. To address this, a push plate is installed. When the drive assembly is activated, the swing arm drives the push plate to move towards the stop bar, thereby changing the original conveying path of the glass bottles. Under the conveyor frame, the push bar falls into the waste recycling line, thus accelerating the removal rate of a large number of defective products.
[0017] Preferably, the push plate is arranged in an arc shape away from the first baffle.
[0018] By adopting the above technical solution, the glass bottle tank can be moved closer to the waste recycling line.
[0019] Preferably, a connecting rope connects the swing arm and the push plate.
[0020] By adopting the above technical solution, the swing arm and the push plate are connected by a connecting rope so that the push plate can be reset, thereby reducing the possibility of some qualified products falling onto the waste recycling line.
[0021] Preferably, the lower end of the swing arm is hinged to a slider, and the outer side wall of the push plate is provided with a groove for the slider to slide and connect.
[0022] In summary, this utility model has the following beneficial effects:
[0023] 1. After the drive assembly is activated to rotate the swing arm, it pushes the glass bottle. Under the thrust of the swing arm, the bottle pushes the stop lever to open the rejection port, detaching it from the conveyor frame and causing it to fall onto the waste recycling line. This method has a relatively short operation time, thereby improving the rejection effect of waste products, and the cost is relatively low. Several of these rejection devices can be installed to further improve the rejection effect.
[0024] 2. A push plate is provided. When the drive assembly is activated, the swing arm pushes the push plate toward the stop bar, thereby changing the original conveying path of the glass bottles. Under the conveyor frame, the push bar falls into the waste recycling line, thereby accelerating the rejection rate of a large number of waste products. Attached Figure Description

Detailed Implementation
[0032] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail below.
[0033] This application discloses a waste and defective product rejection device for a glass production line.
[0034] Example 1:
[0035] A defective product rejection device for a glass production line, referring to Figure 1 The baffle 2 is provided on the conveyor frame 1 for conveying glass bottles 11. In this embodiment, there are two baffles 2, which are respectively located near the two sides of the conveyor frame 1 and are fixedly connected to the side wall of the conveyor frame 1, thereby restricting the travel path of the glass bottles 11. A gap is left between the baffle 2 and the upper surface of the conveyor frame 1.
[0036] The rejection device specifically includes a support 3 mounted on the conveyor frame 1, a rejection mechanism 4 mounted on the support 3, and a baffle 5 mounted on the side of the baffle 2. A waste recycling line 12 for recycling rejected waste products is provided below the conveyor frame 1.
[0037] Specifically, the bracket 3 includes a vertical rod 31 fixedly connected to the side wall of the baffle 2, a horizontal rod 32 vertically fixedly connected to the vertical rod 31, and a mounting groove 33 fixedly connected to the side wall of the horizontal rod 32. In this embodiment, the length direction of the vertical rod 31 is parallel to the height direction of the conveying frame 1, the horizontal rod 32 is an L-shaped rod, the width direction of the mounting groove 33 is parallel to the conveying direction of the glass bottle 11, and the groove opening of the mounting groove 33 is set on the upper surface of the conveying frame 1.
[0038] Reference Figure 1 , Figure 2 The rejection mechanism 4 specifically includes a swing arm 41 rotatably connected to the bracket 3 for pushing the defective glass bottles 11 towards the baffle 5, and a drive assembly 42 mounted on the bracket 3 to drive the swing arm 41 to rotate. The side wall of the baffle 2 has a rejection opening 21, and the baffle 2 is equipped with a rotating assembly 6 for driving the baffle 5 to rotate and open / close the rejection opening 21.
[0039] It should be noted that regarding the configuration of the swing arm 41, when only one side of the baffle 2 has a rejection port 21, the swing arm 41 can be positioned vertically on the other side where no rejection port 21 is provided. When both baffles 2 have rejection ports 21 along the axis of the swing arm 41 and corresponding stop bars 5 are provided, the upper end of the swing arm 41 can be positioned on the center line of the two baffles 2. In this case, the initial position of the swing arm 41 is inclined to the center line of the two baffles 2, so as to reject defective glass bottles 11 during the back-and-forth swing of the swing arm 41, thereby reducing the time spent on the swing arm 41 resetting and further accelerating the rejection rate of defective products. In this embodiment, the latter state of the swing arm 41 is specifically shown.
[0040] Reference Figure 2 , Figure 3 The lower end of the swing arm 41 is located above the baffle 2, and the upper end of the swing arm 41 is fixedly connected to a rotating plate 411. The rotating plate 411 is a circular plate, and the axis of the rotating plate 411 is parallel to the width direction of the mounting groove 33. The rotating plate 411 is built into the mounting groove 33. The rotating plate 411 is coaxially connected to a first rotating rod 412, and the two ends of the first rotating rod 412 are rotatably connected to the opposite side walls of the mounting groove 33.
[0041] The drive assembly 42 specifically includes a gear ring 421 coaxially sleeved on the outer peripheral wall of the rotating plate 411, a drive gear 422 meshing with the gear ring 421, and a drive motor 423 driving the drive gear 422 to rotate. The gear ring 421 is an incomplete gear ring 421. The drive gear 422 is built into the mounting groove 33 and rotatably connected to the opposite side walls of the mounting groove 33. The drive motor 423 is fixedly connected to the outer side wall of the mounting groove 33. The output shaft of the drive motor 423 rotatably passes through the mounting groove 33 to be fixedly connected to the drive gear 422.
[0042] Reference Figure 4 The rotating assembly 6 includes a rotating component 61 that drives the stop lever 5 to rotate, and an elastic component 62 disposed on the rotating component 61. In this embodiment, the rotating component 61 is a second rotating rod. The side wall of the baffle 2 is provided with a rotating groove 22, the length direction of which is parallel to the height direction of the baffle 2. The two ends of the second rotating rod are respectively rotatably connected to the top and bottom walls of the rotating groove 22. In this embodiment, the elastic component 62 is a torsion spring sleeved on the second rotating rod. Under normal conditions, the torsion spring forces the stop lever 5 to close the rejection port 21.
[0043] Specifically, for the swing arm 41, the machine vision first detects the non-conforming items and transmits the corresponding data to the host computer (not shown in the figure) for processing. The corresponding operation command is then sent to the controller (not shown in the figure), which is electrically connected to the drive motor 423. The controller starts the drive motor 423 to rotate forward or backward to drive the drive gear 422 to rotate, thereby driving the swing arm 41 to rotate and apply a pushing force to the defective glass bottle 11. The defective glass bottle 11 is pushed by the swing arm 41 to push the stop bar 5 to detach from the conveyor frame 1 and fall into the waste recycling line 12.
[0044] It should be noted that the rejection device can be arranged in several intervals along the length of the baffle 2 to improve the rejection effect of defective products.
[0045] The implementation principle of a defective product rejection device for a glass production line according to an embodiment of this application is as follows: When a defective product is detected by machine vision, the corresponding data is transmitted to a host computer. The host computer then transmits the corresponding operation command to a controller. The controller activates the drive assembly 42 to rotate the swing arm 41, which in turn pushes the glass bottle 11. Under the thrust of the swing arm 41, the bottle 11 pushes the stop lever 5 to open the rejection port 21, allowing it to detach from the conveyor frame 1 and fall onto the defective product recycling line. By using the swing arm 41 to detach the defective glass bottle 11 from the conveyor frame 1, the operation time is relatively short, thereby improving the rejection effect of defective products.
[0046] Example 2:
[0047] Reference Figure 5 The difference from Embodiment 1 is that the two baffles 2 are a first baffle 23 and a second baffle 24, respectively. The rejection port 21 is disposed on the first baffle 23, and the waste recycling line 12 is disposed on the side of the first baffle 23 away from the second baffle 24. In this embodiment, the rejection mechanism 4 also includes a push plate 43 rotatably connected to the second baffle 24, and a swing arm 41 is used to push the push plate 43 to move towards the baffle bar 5. The push plate 43 is arranged in an arc shape away from the first baffle 23.
[0048] Regarding the connection between the swing arm 41 and the push plate 43, the swing arm 41 can abut against one side of the push plate 43 or be connected to the push plate 43. Specifically, a connecting rope (not shown in the figure) can be provided. The connecting rope can be made of elastic rope, and the specific configuration depends on the requirements. The two ends of the connecting rope are respectively connected to the surfaces of the swing arm 41 and the push plate 43 that are close to each other. Alternatively, a slider (not shown in the figure) can be hinged to the lower end of the swing arm 41. Figure 6 As shown, the slider and the swing arm 41 are connected by a universal ball bearing for steering. The outer wall of the push plate 43 is provided with a sliding groove 431 for the slider to slide and connect. The length direction of the sliding groove 431 is inclined to the length direction of the push plate 43 and is arc-shaped so that after the lower end of the swing arm 41 rotates and the height position changes, it can slide along the length direction of the sliding groove 431 to push the push plate 43 to abut against the first baffle 23. This allows the glass bottle 11 to fall into the waste recycling line 12 after being conveyed by the conveyor frame 1, following the arc of the push plate 43 and pushing the baffle 5.
[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
