[0033] The spray needle misalignment determination process of the bottle washing machine: first step, the first detection mechanism 6 detects the time t1 when the tracking frame 4 is in place, and the second detection mechanism detects the time t2 when the rotating disc 2 is in place; second step, the calculation module calculates the difference T between t1 and t2, and compares T with the set range, if T exceeds the set range, it is determined that the spray needle 5 and the bottle clamping mechanism 3 are misaligned.

[0034] Further, in the embodiment, the rotating disc 2 is provided with a rotating detection position, the tracking frame 4 is provided with a swing detection position, the time t2 when the rotating disc 2 is in place is the alignment time of the second detection mechanism and the rotating detection position, and the time t1 when the tracking frame 4 is in place is the alignment time of the first detection mechanism 6 and the swing detection position. The position of the tracking frame 4 is calibrated by the swing detection position, and the position of the rotating disc 2 is calibrated by the rotating detection position, the alignment time of the first detection mechanism 6 and the swing detection position is the time t1 when the tracking frame 4 is in place, the alignment time of the second detection mechanism and the rotating detection position is the time t2 when the rotating disc 2 is in place, and the structure is designed ingeniously, so that the detection can be smoothly and accurately carried out.

[0035] Further, in the embodiment, the first detection mechanism 6 comprises a first proximity switch 61 and a first trigger block 62 for triggering the first proximity switch 61, the first proximity switch 61 and the first trigger block 62 are respectively arranged on the swing detection position of the support frame 1 and the tracking frame 4, and the first proximity switch 61 is signal connected with the computing module.

[0036] Further, in the embodiment, the first proximity switch 61 is arranged on the support frame 1, and the first trigger block 62 is arranged on the swing detection position of the tracking frame 4. The first proximity switch 61 is fixed, and the first trigger block 62 swings with the tracking frame 4 relative to the first proximity switch 61, so that the detection is accurate.

[0037] Further, in the embodiment, the second detection mechanism comprises a second proximity switch 71 and a second trigger block 72 for triggering the second proximity switch 71, the second proximity switch 71 and the second trigger block 72 are respectively arranged on the rotation detection position of the support frame 1 and the turntable 2, and the second proximity switch 71 is signal connected with the computing module. The time when the second trigger block 72 triggers the second proximity switch 71 is the time t2 when the turntable 2 is in place.

[0038] Further, in the embodiment, the second proximity switch 71 is arranged on the support frame 1, and the second trigger block 72 is arranged on the rotation detection position of the turntable 2. The second trigger block 72 rotates with the turntable 2 relative to the second proximity switch 71, so that the detection is accurate.

[0039] Further, in the embodiment, the rotation detection position is provided with N, which are arranged at intervals in the circumferential direction of the turntable 2, and N is equal to the number of times of reciprocating movement of the tracking frame 4 in one rotation of the turntable 2. In this way, one second trigger block 72 is arranged on each rotation detection position, and the second trigger block 72 is also provided with N, so that the second proximity switch 71 is triggered N times in one rotation of the turntable 2, which is equivalent to detecting N times, thereby improving the detection frequency.

[0040] The bottle clamping mechanism 3 is installed on the turntable 2 to move in the circumferential direction with the turntable 2, and the spray needle 5 is installed on the tracking frame 4 to move in the circumferential direction and reciprocatingly in the vertical direction with the tracking frame 4. A swing detection position is arranged on the tracking frame 4, and a first trigger block 62 is arranged on the swing detection position. The turntable 2 is uniformly provided with N rotation detection positions, and each rotation detection position is provided with a second trigger block 72. The bottle washing machine detects the synchronous position of the tracking frame 4 and the spray needle 5. Under normal circumstances, the spray needle 5 is aligned with the bottle mouth on the bottle clamping mechanism 3 at this time, but the spray needle 5 has not yet been inserted into the bottle in the height direction. If the time difference detected by the second proximity switch 71 on the turntable 2 and the first proximity switch 61 on the tracking frame 4 exceeds the set range, it is determined that the spray needle 5 is misaligned with the bottle mouth on the bottle clamping mechanism 3, the equipment is stopped, and the collision between the spray needle 5 and the bottle clamping mechanism 3 is prevented.

[0041] Further, in the embodiment, the rotating disc 2 is coaxially provided with an inner ring gear 21, the support frame 1 is provided with a gear 11, the gear 11 is engaged with the inner ring gear 21 and connected with a rotating driving mechanism 8. The rotating driving mechanism 8 drives the rotating disc 2 to rotate through the engagement and transmission of the gear 11 and the inner ring gear 21.

[0042] Further, in the embodiment, the tracking frame 4 is connected with a swing mechanism 9, the support frame 1 is provided with a lifting mechanism 12, and the tracking frame 4 is swingably arranged on the lifting mechanism 12. The swing mechanism 9 is used to drive the tracking frame 4 to swing to realize the reciprocating tracking movement of the rotating disc 2 and can move up and down with the lifting mechanism 12.

[0043] Further, in the embodiment, as shown in Figure 4 The rotating disc 2 is provided with a guide block below the bottle clamping mechanism 3, the guide block is above the spray needle 5 and the spray needle 5 passes through the guide block. The guide block is provided with a guide hole, and the fitting range of the guide hole and the spray needle 5 is the alignment range of the spray needle 5 and the bottle clamping mechanism 3. If the center of the spray needle 5 deviates from the guide hole, but the spray needle 5 is still within the fitting range of the guide hole, that is, the spray needle 5 can be inserted into the guide hole without being blocked by the side wall of the guide hole, it means that the spray needle 5 is still within the alignment range of the spray needle 5 and the bottle clamping mechanism 3. In this way, according to the difference T and the linear velocity V of the center of the bottle mouth of the bottle clamping mechanism 3 on the rotating disc 2, the offset distance L of the spray needle 5 and the center of the bottle mouth of the bottle clamping mechanism 3 on the rotating disc 2 can be calculated, L = VT. If L exceeds the alignment range of the spray needle 5 and the bottle clamping mechanism 3, it is determined that the spray needle 5 and the bottle clamping mechanism 3 are misaligned and dislocated.

[0044] Further, the operation process of the tracking frame 4 is as follows: the tracking frame 4 moves at the same speed and in the same direction as the rotating disc 2, and moves in the opposite direction of the rotating disc 2. When the tracking frame 4 is at the starting position of the tracking movement, the tracking frame 4 drives the spray needle 5 to rise, so that the spray needle 5 is inserted into the bottle mouth of the bottle clamping mechanism 3 on the rotating disc 2. Before the rotating disc 2 is at the end position of the tracking movement, the tracking frame 4 drives the spray needle 5 to descend, so that the spray needle 5 is pulled out of the bottle mouth of the bottle clamping mechanism 3 on the rotating disc 2. The swing detection position is arranged at the starting position of the tracking movement of the tracking frame 4, so that the spray needle 5 is aligned with the bottle mouth of the bottle clamping mechanism 3 on the rotating disc 2 at the starting position of the tracking movement.

[0048] S2, a calculation module calculates the difference T between t1 and t2, and compares T with a set range. If T exceeds the set range, it is determined that the spray needle 5 and the bottle clamping mechanism 3 are misaligned and dislocated.

[0049] In the event that the needle 5 and the bottle clamping mechanism 3 are misaligned, the machine is immediately stopped for maintenance. The needle misalignment determination method of the bottle washing machine uses the detected time difference to accurately determine the relative position of the needle 5 and the bottle clamping mechanism 3, avoids continued operation when misaligned, reduces needle 5 wear and tear, and reduces maintenance costs.
