Small-end connected selection equipment for convenient chopsticks

[0016] Such as figure 1 , 2 , 3, 4, and 5 show: 1 is the frame, which can be made by welding section steel. A driven shaft 2 and a driving shaft 26 connected to the driving mechanism are supported on the frame 1 through bearings. Sprockets are installed on the driving shaft 26 and the driven shaft 2 and are equipped with a double-row transmission for convenient chopsticks 7 Chain 12. A symmetrical protrusion 14 for pushing the chopsticks 7 forward is provided on the chain plates that make up each conveyor chain 12, that is, on the inner chain plate of each row of chains 12, there are protrusions that are integrated with the chain plates. The protrusion 14 is formed.

[0017] On the outer side of the conveying chain 12 on the frame 1, a left sliding table 13 and a right sliding table 30 are respectively provided to support the convenient chopsticks 7. The conveying chain 12 is lower than the upper plane of the left sliding table 13 and the right sliding table 30, and the protruding part 14 extends upward from the upper plane of the left sliding table 13 and the right sliding table 30. When the conveying chain 12 is running, it is pushed by the protrusion 14 to facilitate the forward movement of the chopsticks 7 and facilitate the two ends of the chopsticks 7 to fall on the left sliding table 13 And the right sliding table 30, sliding on the left sliding table 13 and the right sliding table 30.

[0018] A feeding mechanism is provided at one end of the frame 1. A position sensor 19 or a contact switch connected to the electric control device is fixedly connected to the left sliding table 13 by screws. The position sensor 19 or contact switch is here or select the position sensor 19 or select the contact switch, which is used to detect whether the small heads of the convenient chopsticks 7 can be separated, in other words whether the small heads of the convenient chopsticks 7 are connected together, and The collected signal is transmitted to the electronic control device.

[0019] On the frame 1 behind the position sensor 19 or the contact switch, there is a blowing port 23 connected to the air supply device, and the blowing direction of the blowing port 23 is directed to the convenient chopsticks 7 running there.

[0020] A cross beam 20 is fixedly supported above the frame 1, and an elastic pressing piece 16 is fixedly connected to the cross beam 20 by screws. The end of the elastic pressing piece 16 is pressed to run to the position sensor 19 or the convenient chopsticks 7 at the contact switch. . In order to have a better pressing effect, the elastic pressing member 16 can be a spring leaf, the end is warped and there is a protrusion 34 underneath (see Figure 4 ). The elastic pressing member 16 may also be in the shape of an elastic rod, and a roller is installed at the end, and the convenient chopsticks 7 running here are pressed by the roller. The lower frame 1 of the elastic pressing member 16 is provided with a flat plate 36, and the upper plane of the flat plate 36 is flush with the upper planes of the left sliding table 13 and the right sliding table 30.

[0021] The lower frame 1 of the convenient chopsticks 7 running under the position sensor 19 or the contact switch is provided with a convenient chopstick head separating mechanism. The separating mechanism has two structural forms.

[0022] Such as image 3 , 4 , 5: One of the mechanisms to facilitate the separation of the small heads of chopsticks is to install a rotating shaft 17 on the frame 1 through a bearing. On the rotating shaft 17 is installed a supporting wheel 18 that matches the transmission chain 12 on one side. The front side of the outlet 14 is provided with a narrow platform 15 that supports half the width of the small head of the chopsticks 7, and the supporting wheel 18 just lifts the conveyor chain 12 running there, that is, the conveyor chain 12 is raised here. At the same time, the protruding portion 14 and the narrow platform 15 on the front side are raised accordingly. Due to the existence of the elastic pressing member 16 here, the narrow platform 15 will have a rotational displacement (a tilted) half of the convenient chopsticks 7 on it. The other half hanging on the outside of the narrow platform 15 does not produce upward rotational displacement, which means that the small heads of the chopsticks can be separated, which means that the small heads of the convenient chopsticks 7 are not connected. For example, the other half hanging on the outside of the narrow platform 15 will move upward. Rotational displacement indicates that the small head of the convenient chopsticks is in a conjoined state, which is a non-standard product, and the signal collected by the position sensor 19 or the contact switch is transmitted to the electric control device. If a contact switch is selected, and the contact part of the contact switch is set on the left sliding table 13, when each convenient chopstick 7 is transported here, half of the non-upward rotational displacement will touch the contact switch , Which means that the small heads can be separated. If they don’t touch each other, it means that the other half hanging on the outside of the narrow platform 15 will be tilted upwards. It also means that the small heads of chopsticks can be connected together to transmit the signal to the electronic control device.

[0023] Such as Figure 4 , 6 Shown: another convenient chopstick head separation mechanism includes a rotating shaft 17 mounted on the frame 1 through a bearing. On the rotating shaft 17 is equipped a supporting wheel 18 and a supporting wheel 33 that match the transmission chain 12, and the supporting wheel 18 is here. It only rotates with the conveying chain 12, thereby driving the rotation shaft 17 to rotate. The difference from the previous separating mechanism is that the conveying chain 12 here does not lift up. Abutting tables 32 arranged axially are evenly distributed around the periphery of the abutting wheels 33. When the abutting wheels 33 rotate, each abutting table 32 just supports up to half of the convenient chopsticks 7 running here, due to the elastic pressing member 16 The small head of the convenient chopsticks 7 running here is lifted up and the other half does not move upwards, that is, the small heads of the convenient chopsticks 7 are separated, which means that the small heads of the convenient chopsticks 7 are not connected. The two parts of the convenient chopsticks 7 have an upward rotational displacement, which means that the small head of the convenient chopsticks 7 is one-piece, which is a substandard product. The signal collected by the position sensor 19 or the contact switch is transmitted to the electric control device. If a contact switch is selected, the contact part of the contact switch is set on the left sliding table 13, and the end of each convenient chopstick 7 touches the contact of the contact switch, indicating that the small head of the convenient chopstick 7 is separable If the small head of the convenient chopsticks 7 collides with the contact of the contact switch, it means that all the small heads of the convenient chopsticks 7 have a rotational displacement upwards, that is, the small heads of the convenient chopsticks 7 are connected together. For qualified products, the signal is transmitted to the electronic control device.

[0024] The above-mentioned unqualified products detected are all delayed by the electronic control device to control the opening of the valve of the air supply device, so that the unqualified products are blown out when they run to the blowing port 23.

[0025] Such as figure 1 , 2 As shown: the feeding mechanism includes a feeding box 3 connected to the front end of the frame 1, a brush wheel shaft 5 is installed in the feeding box 3 through a bearing, and a brush wheel 6 is installed on the brush wheel shaft 5. The feeding box 3 phase is equipped with a double-row feeding conveyor chain 4 that is connected to the power mechanism and is inclinedly arranged. The power mechanism is a motor reducer. The motor reducer is used to drive the brush wheel shaft 5 and the brush wheel 6 to rotate. The feeding conveyor chain 4 is uniformly fixed and connected with convex bars in the transverse direction. The upper end of the inclined feeding conveyor chain 4 matches with one end of the conveying chain 12, and the periphery of the brush wheel 6 is just placed on the convenient chopsticks 7 on the inclined feeding conveyor chain 4. on. During operation, the convenient chopsticks 7 in the loading box 3 are brought up by the convex strips, and each convex strip brings a convenient chopsticks 7, if more than one can use the brush wheel 6 to block the falling, and then enter the conveyor chain 12. Propelled by the protrusion 14 to facilitate the chopsticks 7 to move forward along the left sliding table 13 and the right sliding table 30.

[0026] Such as figure 1 , 2 Shown: the driving mechanism includes a motor 31 and a reducer 29 installed on the frame 1. The motor 31 is connected to the input shaft of the reducer 29, the output shaft of the reducer 29 is equipped with a sprocket, and the driving shaft 26 is equipped with a sprocket , The sprocket on the reducer 29 and the sprocket on the driving shaft 26 are connected by a drive chain 27.

[0027] A suction hood connected to the air induction device is arranged above the air blowing port 23, and the unqualified chopsticks 7 blown out by the blowing port 23 during operation can be sucked out through the suction hood.

[0028] A receiving box 25 is connected to the rear end of the rack 1, and a lower slide plate 24 is fixed on the rack 1 above the receiving box 25. The convenient chopsticks 7 falling from the conveyor chain 12 can slide down to the receiving box through the lower slide plate 24 Within 25.

[0029] The above-mentioned position sensor 19 is equipped with a U-shaped photoelectric switch connected with the electric control device.

[0030] Use this equipment to select convenient chopsticks with fast speed, automatic operation, saving time and effort, reducing the labor intensity of operators, improving work efficiency, and conforming to the standard of unqualified products.
