AI Technical Summary
In the appearance quality inspection of the existing online caching devices, the plastic bottles on the cache platform are disorderly, have large movement amplitude, relatively large collision amplitude, and bottle inversion, and reduce the effective utilization area of the cache platform.
An online buffering device is designed to achieve intermittent material pushing by setting a spacer mechanism and a material pushing mechanism on both sides of the conveyor belt. When the plastic bottle is fully loaded, it will reduce the amplitude of a single movement, and control the action of the spacer mechanism through a counter or pressure sensor to improve the cache order and efficiency.
The single movement of plastic bottles on the cache platform is small, neatly placed, large cache amount, and no bottle inversion, which improves the effective utilization area of the cache platform and the work efficiency of the operators.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of plastic packaging bottle production equipment and relates to an online buffer device for appearance quality inspection of plastic bottles. Background Art
[0002] Online appearance inspection of plastic bottles after water cutting is generally done manually. Since manual work is difficult to synchronize with the equipment (the discharge frequency of the equipment), and the operators may temporarily leave their posts (such as going to the bathroom, etc.), online appearance inspection requires online caching of plastic bottles. In the prior art, Figure 4 As shown, a baffle is set on the plastic bottle conveyor line, and the baffle is used to guide the plastic bottles to the buffer platform. After the operator takes the plastic bottles on the buffer platform for inspection, the qualified products are placed at the tail end of the conveyor line for continued operation. In this way, the baffle for guiding the plastic bottles will not only cause the plastic bottles on the buffer platform to be disorderly, but also the plastic bottles will have a large movement amplitude on the buffer platform, a relatively large collision amplitude, and there is a situation of falling bottles. It will also reduce the effective utilization area of the buffer platform (the baffle is inclined, and part of the space is wasted). Utility Model Content
[0003] The purpose of the utility model is to provide an online caching device for plastic bottle appearance quality inspection in view of the above problems existing in the prior art. The technical problem to be solved by the utility model is how to optimize the online caching order of appearance quality inspection.
[0004] The purpose of the utility model can be achieved through the following technical solutions: an online caching device for appearance quality inspection of plastic bottles, the plastic bottle production line includes a conveyor belt, guardrails located on both sides of the conveyor belt, and a caching platform, the guardrail on one side of the conveyor belt has a notch, and the caching platform is located at the notch, and it is characterized in that two barrier mechanisms are arranged on the conveyor line and are respectively located on both sides of the notch, and a pushing mechanism corresponding to the notch is provided at the guardrail on the side away from the caching platform, and the pushing mechanism includes a cylinder and a push plate fixed on the cylinder, and the push plate corresponds to the notch.
[0005] Furthermore, a counter is provided at the barrier mechanism close to the material delivery direction of the conveyor belt.
[0006] As another option, a pressure sensor is provided at the barrier mechanism close to the discharging direction of the conveyor belt.
[0007] The blocking mechanism can be a telescopic cylinder, the push rod of the telescopic cylinder is inserted above the conveyor belt, and the conveying path is laterally blocked, that is, the online conveying of plastic bottles is stopped. It can also be a motor, and a crank is connected to the output circle of the motor. A baffle is fixed on the crank. The baffle can block the plastic bottles in a vertical state, and when the baffle is flipped to a higher position from the conveyor belt, it is in a horizontal state and does not interfere with the online movement of the plastic bottles.
[0008] In this solution, the traditional natural material guiding is changed to intermittent material pushing. When the conveyor belt between the two baffle mechanisms is fully loaded with plastic bottles, the baffle mechanism close to the incoming direction blocks the conveying path, the pushing mechanism is actuated, and the push plate pushes the corresponding number of plastic bottles to the buffer platform. After the horizontal pushing action is completed, the push plate is reset, and the baffle mechanism in the incoming direction reopens the conveying path, and the plastic bottles continue to move. This is repeated. The baffle mechanism in the outgoing direction blocks the conveying path under normal conditions. The existence of the baffle mechanism in the outgoing direction can improve the versatility of the production line and can be opened when manual inspection of the appearance is not required. During manual operation, the plastic bottles on the buffer platform are taken for inspection, and the qualified products are taken to the conveyor line behind the gap to continue running. Compared with the existing technology, this method has a smaller single movement range of the plastic bottles on the buffer platform, the plastic bottles are relatively neatly arranged, the buffer volume is large, there is no bottle overturning, and the controllable time for the operator to temporarily leave the post is longer.

[0014] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0015] Embodiment 1
[0016] like Figure 1As shown, an online caching device for appearance quality inspection of plastic bottles, the plastic bottle production line includes a conveyor belt 1, guardrails 2 located on both sides of the conveyor belt 1, and a caching platform 3. The guardrail 2 on one side of the conveyor belt 1 has a notch 4, and the caching platform 3 is located at the notch 4. Two barrier mechanisms 5 are provided on the conveyor line, which are respectively located on both sides of the notch 4. The guardrail 2 on the side away from the caching platform 3 is provided with a pushing mechanism 6 corresponding to the notch 4. The pushing mechanism 6 includes a cylinder and a pushing plate fixed on the cylinder, and the pushing plate corresponds to the notch 4.
[0017] A counter is provided near the barrier mechanism 5 in the incoming direction of the conveyor belt 1. The counter counts the number of incoming bottles. When the number is consistent with the number of full loads between the two barrier mechanisms 5, the control center sends an action instruction to the barrier mechanism 5 in the incoming direction, and the barrier mechanism 5 in the incoming direction is adjusted from the open state to the stop state. After the push mechanism 6 completes the action and resets, the barrier mechanism 5 in the incoming direction is adjusted from the stop state to the open state.
[0018] The blocking mechanism 5 can be a telescopic cylinder, the push rod of which is inserted above the conveyor belt 1 to perform transverse blocking on the conveying path, thereby achieving a stop for the online conveying of plastic bottles. It can also be a motor, with a crank connected to the output circle of the motor, and a baffle fixed on the crank. The baffle can block the plastic bottles in a vertical state, and is in a horizontal state when it is flipped to a higher position from the conveyor belt 1, and does not interfere with the online movement of the plastic bottles.
[0019] In this solution, the traditional natural material guide is changed to intermittent material pushing. When the plastic bottles are fully loaded on the conveyor belt 1 between the two baffle mechanisms 5, the baffle mechanism 5 close to the incoming direction blocks the conveying path, and the pushing mechanism 6 is activated. The push plate pushes the corresponding number of plastic bottles to the buffer platform 3. After the horizontal pushing action is completed, the push plate is reset, and the baffle mechanism 5 in the incoming direction reopens the conveying path, and the plastic bottles continue to move. This is repeated. The baffle mechanism 5 in the discharge direction normally blocks the conveying path. The existence of the baffle mechanism 5 in the discharge direction can improve the versatility of the production line and can be opened when no manual inspection of the appearance is required. During manual operation, the plastic bottles on the buffer platform 3 are taken for inspection, and the qualified products are taken to the conveyor line behind the gap 4 to continue running. Compared with the existing technology, this method has a smaller single movement range of the plastic bottles on the buffer platform 3, and the plastic bottles are placed relatively neatly, with a large buffer volume, no bottle overturning, and a longer controllable time for the operator to temporarily leave the post.
[0020] Embodiment 2
[0021] This embodiment is basically the same as the first embodiment, except that: the judgment method of the barrier mechanism 5 for controlling the incoming direction is adjusted to a pressure sensor, and the pressure sensor is arranged at the barrier mechanism 5 corresponding to the discharging direction. If the barrier mechanism 5 is a flippable baffle mechanism, then the pressure sensor is arranged on the pressure surface of the baffle. When the plastic bottles between the two barrier mechanisms 5 are fully loaded, the plastic bottles squeeze each other, and the pressure applied to the pressure sensor increases. At this time, it is judged to be fully loaded. At this time, the barrier mechanism 5 in the incoming direction chooses whether to implement the stopping action according to whether it is fully loaded.
[0022] In addition, two material guide plates are symmetrically arranged at the end of the cache platform 3 to facilitate the removal of plastic bottles on the cache platform 3. In actual operation, the cache platform 3 may be fully loaded and need to be removed to avoid material jamming on the cache platform 3.
[0023] The specific embodiments described herein are merely examples of the spirit of the present invention. A person skilled in the art of the present invention may make various modifications or additions to the specific embodiments described or replace them in a similar manner, but this will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
