Detailed Implementation

[0036] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0037] (Example 1)

[0038] like Figures 1 to 4 The collision alarm device shown is used in bottle filling production. It includes a conveyor 100 for transporting bottles and a first crossbar 1 and a second crossbar 2 that are vertically adjustable and arranged in parallel. Multiple actuators 3 are arranged along the length of the first crossbar 1. The actuators 3 are filling needles, washing needles, or blowing needles; in this embodiment, the actuator 3 is a filling needle. Bottle clamping blocks 4, coaxially corresponding to each filling needle, are fixedly mounted on the second crossbar 2 to limit the posture of the bottles transported by the conveyor 100. The second crossbar 2 slides vertically below the first crossbar 1. Oppositely arranged photoelectric sensors 5 are fixedly mounted at both ends of the first crossbar 1. The filling needles are all vertically slidably mounted on the first crossbar 1 and are equipped with sensing parts 3-1 suitable for blocking the photoelectric signals from the photoelectric sensors 5. When any filling needle collides with a bottle, it is forced to rise relative to the first crossbar 1, thereby cutting off the photoelectric signal through the sensing parts, triggering an alarm, stopping the filling process, and awaiting personnel intervention to avoid filling waste.

[0039] Specifically, the conveyor 100 has parallel and spaced input lines 101 and output lines 102. The filling needle is located between the input lines 101 and output lines 102. The conveyor 100 is equipped with bottle holder groups 103 for limiting the spacing between bottles. The bottle holder groups 103 are arranged in two parallel rows and slide horizontally on the conveying plane perpendicular to the conveying direction. A bottle pushing mechanism 104 and a bottle blocking mechanism 105 are located on the side of the input lines 101. By setting up the bottle holder groups 103, on the one hand, the bottles can be conveyed at equal intervals, and on the other hand, the overall posture of the bottles is relatively stable and not easily tipped over. Furthermore, the bottles can be moved horizontally on different conveyor lines, facilitating production line layout, avoiding long conveyor lines, reducing equipment footprint, and shortening bottle entry waiting time, thus improving filling efficiency.

[0040] The bottle blocking mechanism 105 is arranged close to the entrance of the input line 101, and includes a bottle blocking cylinder 105-1 fixed on the conveyor 100, which is horizontally arranged perpendicular to the conveying direction and is fixed with a bottle blocking block 105-2, which is adapted to the gap between adjacent bottle holders of the bottle holder group 103 and is adapted to be inserted thereinto to block the subsequent bottle conveying.

[0041] The bottle pushing mechanism 104 includes a bottle pushing cylinder 104-1 fixed on the side of the conveyor 100, which is horizontally arranged perpendicular to the conveying direction and is fixed with a bottle pushing plate 104-2, which is adapted to the length of the bottle holder group 103 in each translation, so as to move a corresponding number of bottle holders to the filling needle for filling, and when the bottle pushing mechanism 104 is pushed again, the bottle that has been filled is translated to the output line 102 again and is output by the output line 102.

[0042] The outer sides of the input line 101 and the output line 102 are also symmetrically provided with guardrails 106 corresponding to the bottle pushing plate 104-2, so as to prevent the bottles from falling off the conveying line during pushing and improve the stability of the bottle conveying.

[0043] In order to further ensure the accuracy of the bottle clamping during filling, the bottom of the bottle clamping block 4 of the embodiment is provided with an inverted trumpet-shaped positioning groove, which ensures that the bottle body remains vertical, so that the slightly inclined bottle body is righted.

[0044] In order to realize the lifting setting of the first horizontal rod 1, the embodiment is provided with a rack 6, which is provided with a lifting assembly, and the lifting assembly includes a linear drive mechanism 7 fixed on the bottom of the rack 6, which is a hydraulic cylinder or a pneumatic cylinder, which is simple in structure, fast in control response and sufficient in power, and the output end of the linear drive mechanism 7 is vertically upwardly arranged and is fixed with a lifting frame 8, and the first horizontal rod 1 is fixed on the top of the lifting frame 8 and realizes lifting movement under the driving of the linear drive mechanism 7. The two ends of the first horizontal rod 1 are fixed with linear bearings 9, and the two ends of the second horizontal rod 2 are fixed with guide rods 10 which are in sliding cooperation with the linear bearings 9, so that the second horizontal rod 2 is lifted synchronously with the first horizontal rod 1 without external force.

[0045] The first horizontal rod 1 is fixed with a slide sleeve 11 corresponding to the filling needle, and the filling needle is slidingly inserted into the slide sleeve 11, and an inlet pipe is arranged at the upper portion for feeding, and the inlet pipe is provided with a flat section below the active signal of the active sensor 5, and the flat section extends to the front and rear of the active sensor at both ends, forming an induction portion 3-1, and the initial longitudinal vertical distance between the induction portion 3-1 and the active signal is less than the safe sliding distance of the filling needle relative to the first horizontal rod 1, so as to ensure that the induction portion 3-1 can cut off the active signal.

[0046] The workflow of this embodiment is as follows: During the initial stage of filling production, a through-beam signal is generated between the two through-beam sensors 5. This signal is transmitted through the linear drive mechanism 7 to the lifting frame 8, which in turn drives the first crossbar 1 and the second crossbar 2 to rise and fall synchronously. The process continues until the bottle clamping block 4 locks the bottle opening below, securing the bottle. At this point, the second crossbar 2 remains stationary, while the first crossbar 1 drives the filling needles on it to continue descending for filling. Under normal conditions, all filling needles are inserted into the bottle, and the through-beam signal is always present. When any filling needle collides with the bottle, it is forced to rise relative to the first crossbar 1, thereby cutting off the through-beam signal through the sensing element, triggering an alarm in the equipment, stopping the filling process, and awaiting personnel intervention to avoid filling waste.

[0047] (Example 2)

[0048] This embodiment is used for bottle processing collision alarm during the capping operation after filling. The actuator 3 is a capping head. The rest of the overall structure is similar to that of embodiment 1. The difference is that there is no need to set the second crossbar 2 and the bottle clamping block 4 on it. The through-beam sensor 5 is fixed on the frame 6. The capping head is fixed on the first crossbar 1 and includes a gripper for capping. The capping head is fixed with a sensing plate covering the through-beam signal of the through-beam sensor 5 as the sensing part 3-1. The initial longitudinal vertical distance between the top of the sensing part 3-1 and the through-beam signal is less than the capping descent distance of the capping head.

[0049] The workflow of this embodiment is as follows: During capping production, the linear drive mechanism 7 drives the lifting frame 8 to rise and fall, thereby synchronously raising and lowering the first crossbar 1. Initially, the through-beam signal between the two through-beam sensors 5 is cut off by the sensing unit 3-1. Figure 5 As shown; the capping head on the first crossbar 1 performs the capping action. Under normal conditions, all capping heads descend, and the sensor plate follows and descends synchronously. The through-beam sensor 5 remains stationary, and the through-beam signal is restored, as shown. Figure 6 As shown; when any one of the capping heads collides with the bottle, the entire row of capping heads fails to descend normally, and the signal transmission remains cut off, as... Figure 5 As shown, this triggers an equipment alarm, causing the capping process to stop and await personnel intervention, thus preventing defective products from flowing into the next process.

[0050] This invention optimizes the traditional method of setting an independent photoelectric sensor and photoelectric baffle on each filling needle into a through-beam sensor for monitoring the entire row of actuators, simplifying the structure and reducing costs. By optimizing the actuator 3 into a through-beam sensor 5 arranged opposite each other, when processing the bottle, the actuator 3 descends to process. If it collides with the bottle mouth, the sensing part 3-1 changes the signal state of the through-beam sensor 5. The change in the signal state triggers an alarm in the equipment, causing the processing step to stop.

[0051] The above-described specific embodiments further specifically describe the purposes, technical solutions and beneficial effects of the present application, and it should be understood that the above-described specific embodiments are merely examples of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
