Embodiment 1
[0052] Embodiment one: see Figure 1-14 , a multi-beat screw counting machine, including a screw vibrating plate 1, a screw conveyor track 2, a distribution gear 3, an annular proximity sensor 4, a temporary storage bin 5 and a discharge switch valve 6.
[0053] Preferably, the screw vibrating plate 1 adopts an equally divided helical top plate. If you can choose the Hy-060 screw vibrating plate produced by Dongguan Hongyang Automation Equipment Co., Ltd. see Figure 1-4 One end of the screw conveying track 2 is connected to the outlet of the screw vibrating plate 1, the distribution gear 3 is arranged on the other end of the screw conveying track 2 and when the distribution gear 3 rotates, the screws at the other end of the screw conveying track 2 can be screwed one by one. Dial out; the distribution gear 3 is connected to the first rotary power source 7, and the first rotary power source 7 is used to drive the distribution gear 3 to rotate. Specifically, the screw conveyi...
Embodiment 2
[0074] Embodiment two: a screw counting feeding method, which uses the multi-beat screw counting machine described in embodiment one, the method includes the following steps:
[0075] S100, installing screws in the screw vibrating plate 1;
[0076] S200, set the screw feeding formula (specifically, four setting values 5, 4, 7, 3 can be input respectively through the touch screen); the screw feeding formula includes the number of screw feeding in the first beat (such as 5 screws) , The number of screw feeds in the second beat (such as 4 screws), the number of screw feeds in the third beat (such as 7 screws), the number of screw feeds in the fourth beat (such as 3 screws), and repeat the cycle in turn;
[0077] S310, the PLC controls the discharge switch valve 6 to start work and makes the discharge port 5-2 of the temporary storage bin 5 in a closed state (see Figure 10-11 );
[0078] S320, the PLC controls the screw vibrating plate 1 to start working, and the screw vibrat...

Abstract
The invention discloses a multi-beat screw counter, which is characterized by comprising a screw vibration plate, a screw conveying track, a push-out gear, a ring-shaped proximity sensor, a temporarystorage bin and a discharge switch valve. The push-out gear is arranged on the other end of the screw conveying track and can push out screws in the other end of the screw conveying track one by one.The sensing hole of the ring-shaped proximity sensor is configured to count the screws pushed out by the push-out gear. A receiving port on the upper end of the temporary storage bin is configured toreceieve the screws falling from the sensing hole of the ring-shaped proximity sensor. The discharge switch valve is configured to open or close a discharge port at the lower end of the temporary storage bin. The screw vibration plate, a first rotary power source, the ring-shaped proximity sensor and the discharge switch valve are electrically connected to a PLC. The multi-beat screw counter can feed different numbers of screws in different beats in one cycle, can repeat the cycles, and successively count the screws in multiple beats and repeats the cycles. The invention also discloses a screwcounting and feeding method.
Description
technical field [0001] The invention belongs to a multi-beat screw counting machine and a screw counting feeding method. Background technique [0002] In order to meet the customer's non-standard production needs (such as in the automatic assembly of car seats), the screws are required to be counted in multiple beats and then fed and cycled repeatedly. At the same time, the screw sticking rate is required to be 0.1‰ and the counting error rate is 0.1‰. For example, the required screw feeding formula is: such as: 5 pieces for the first time, 4 pieces for the second time, 7 pieces for the third time, 3 pieces for the fourth time, and then repeat 5 pieces, 4 pieces, 7 pieces, 3 pieces and Continue to repeat the cycle sequentially. In view of the fact that the number of screw feeds per beat is not equal, and the cycle is repeated, correspondingly, multi-beat screw counting and feeding are required and cycled. However, the current screw counting equipment cannot meet the above ...
