Description

Technical Field

[0001] This utility model relates to the field of bottle filling equipment technology, and more specifically, to a device for rejecting defective bottles. Background Technology

[0002] The filling and capping integrated machine is mainly used for the filling and sealing of bottled liquids. Its working principle includes: after the packaging container enters the filling station through the bottle feeding mechanism, it is driven by the filling machine turntable to rotate around the main vertical shaft. After rotating to the next station, the bottle moves upward under the action of the bottle holding mechanism. After filling is completed under the action of the filling mechanism, it moves downward under the action of the bottle holding mechanism, and then enters the next station driven by the rotation of the main vertical shaft. The bottle is then capped by this mechanism. After rotating another angle, the product leaves the filling machine turntable under the action of the bottle exit mechanism, completing the filling and capping process.

[0003] The filling and capping machine integrates filling and capping functions and is mainly used for filling liquid products. This equipment can automatically feed bottles, fill, cap, and discharge bottles without manual operation, which is both hygienic and safe. It also features accurate measurement, stable operation, fast filling speed, and low noise.

[0004] In existing technologies, filling and capping machines often experience problems such as improper capping or misaligned bottles during operation. Defective bottles are conveyed to a conveyor belt, but the vibrations during regular belt operation make detection difficult. Furthermore, the limited installation space prevents the installation of ordinary detection sensors, easily leading to defective products entering the market. Utility Model Content

[0023] Example 1

[0024] The following is in conjunction with the appendix Figure 1-5 The present invention will be further described as follows:

[0025] The present invention provides a defective bottle rejection device 10 based on the existing ZKGX12 / 14 constant pressure filling and capping integrated machine ( Figure 1 The improvements made to this application are not limited to the ZKGX12 / 14 constant pressure filling and capping machine. Please refer to [link / reference needed] for details. Figure 2-5 .

[0026] The defective bottle rejection device 10 includes a bottle dispensing dial assembly 100, a detection device 200, a diversion device 300, a bottle dispensing track 400, a first connecting plate 500, a second connecting plate 600, and a diversion rod 700.

[0027] The bottle dispensing dial assembly 100 includes a bottle dispensing wheel 110 and a guardrail 120, with a detection device 200 positioned above the guardrail 120.

[0028] In this embodiment, the detection device 200 includes a T-shaped double bearing seat 210, a rotating shaft 220, a support base 230, a distance sensor 240, a conductive bolt 250, a metal sensing sheet 260, a first metal conductive sheet 270, and a second metal conductive sheet 280.

[0029] The first connecting plate 500 is connected to the bottle dispensing dial assembly 100, and the support base is connected to the first connecting plate.

[0030] In this embodiment, the metal sensor 260 is disposed above the bottle cap. When the bottle cap is tilted, the metal sensor 260 contacts the bottle cap and moves upward. The rotating shaft 220 passes through the T-shaped double bearing seat 210. The metal sensor 260 is disposed at one end of the rotating shaft 220, and the first metal conductive plate 270 is disposed at the other end of the rotating shaft 220. The T-shaped double bearing seat 210 is detachably connected to the support base 230, and the support base 230 is connected to the bottle dispensing dial assembly 100. The conductive bolt 250 passes through the first metal conductive plate 270. One end of the conductive bolt 250 can contact or separate from the support base 230. By adjusting the conductive bolt 250 up and down, the metal sensor 260 can be triggered when the cap is properly screwed on, and triggered when the cap is improperly screwed on. The second metal conductive plate 280 is in contact with the first metal conductive plate 270. The distance sensor 240 is disposed above the first metal conductive plate 270. One end of the second metal conductive plate 280 is connected to the support base 230, and the other end is connected to the distance sensor 240.

[0031] In this embodiment, the diversion device 300 is disposed on the bottle outlet track 400. The diversion device 300 includes a power distribution control box (not shown), a corner cylinder 310, and a solenoid valve (not shown) connected to the corner cylinder 310. The power distribution control box is externally equipped with a programmable logic controller (PLC) or a time relay. The solenoid valve is electrically connected to the power distribution control box.

[0032] The second connecting plate 600 is connected to the bottle outlet track 400 and positioned above it. A corner cylinder 310 is positioned above the second connecting plate 600, with its rotating rod 311 passing through the second connecting plate 600 and extending towards the bottle outlet track 400. The axis of the rotating rod 311 is perpendicular to the length of the bottle outlet track 400, and the rod 311 is connected to a push plate 320 for pushing the bottle to divert the flow. The distance sensor 240 is electrically connected to a solenoid valve.

[0033] The diverting rod 700 is located below the second connecting plate 600 and connected to the second connecting plate 600. The diverting rod 700 divides the bottle outlet track 400 into a qualified track 410 and an unqualified track 420 along the length of the bottle outlet track 400.

[0034] The defective bottle rejection device 10 provided in this embodiment works as follows:

[0035] Under normal circumstances, the bottle dispensing wheel 110 transports the qualified bottles with caps screwed on to the qualified channel through the transfer device.

[0036] When a bottle with an improperly screwed cap is present, the cap will be slightly higher than a properly screwed cap. At the bottle dispensing impeller, the metal sensor 260 will be slightly lifted upwards, driving the rotating shaft 220, which in turn drives the first metal conductive plate 270 to rise simultaneously. Since the distance sensor 240 is connected to the second metal conductive plate 280, the distance between the first metal conductive plate 270 and the second metal conductive plate 280 changes. The distance sensor 240 detects that the bottle is higher than the set height and determines it to be unqualified (accuracy 0.1MM). At this time, the output (PNP) signal is sent to the external PLC (or time relay) of the power distribution control box of the shunt device 300. The PLC outputs the set time parameter through the delay coil (or the time relay delay) and sends it to the solenoid valve. The solenoid valve opens, thereby driving the rotating rod 311 of the corner cylinder 310 to rotate, which in turn drives the push plate 320 to push the unqualified bottle onto the unqualified bottle track, where the operator will handle it accordingly.

[0037] In summary, the defective bottle rejection device 10 provided in this embodiment has an ingenious structural design. After the bottle is capped, it can automatically detect whether the bottle cap meets the standard and immediately separate and transfer qualified and unqualified bottles. The whole process is fully automated, does not affect the production process, and does not require additional labor costs.

[0038] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
