As shown in fig. 1 to 5, the present invention provides an article output mechanism, which comprises a conveyor belt 1, a first power unit 2 having a driving shaft 21, a first driving wheel 31 mounted on the driving shaft 21, a first driven wheel 33 mounted on a first driven shaft 32, a first transmission belt 34 sleeved on the first driving wheel 31 and the first driven wheel 33, a second driving wheel 41 mounted on the driving shaft 21, a second driven wheel 43 mounted on the second driven shaft 42, a second transmission belt 44 sleeved on the second driving wheel 41 and the second driven wheel 43, a counting wheel 51 mounted on the second driven shaft 42, and a counting sensor 52, wherein a push plate 35 is mounted on the first transmission belt 34, the push plate 35 can push out an article 6 on the conveyor belt 1 along an output direction, the counting wheel 51 is provided with a counting sensing notch 511, when the counting sensing notch 511 on the counting wheel 51 rotates to a position corresponding to the counting sensor 52, the count sensor 52 can sense the count sensing notch 511 on the count wheel 51. The working principle of the article output mechanism in the invention is as follows: the driving shaft 21 of the first power unit 2 rotates and drives the first driving wheel 31 and the second driving wheel 41 to synchronously rotate, the first driving wheel 31 drives the first transmission belt 34 and the first driven wheel 33 to rotate, the first transmission belt 34 drives the push plate 35 to move, and the push plate 35 pushes out the articles 6 on the conveying belt 1 along the output direction, so that the article output mechanism has the function of outputting the articles 6; meanwhile, the second driving wheel 41 drives the second driven wheel 43, the second driven shaft 42 and the counting wheel 51 to rotate through the second transmission belt 44, and each time the counting sensing notch 511 on the counting wheel 51 rotates to a position corresponding to the counting sensor 52, the counting sensor 52 can sense the counting sensing notch 511 on the counting wheel 51 and sequentially measure the number of the rotation cycles of the counting wheel 51; and when the counting wheel 51 rotates for one circle, the first transmission belt 34 rotates for a certain number of circles and drives the push plate 35 to push out a certain number of articles 6 along the output direction, so that the number of pushed articles 6 can be measured by measuring the number of circles of the counting wheel 51; therefore, when the counting sensor 52 detects that the number of revolutions of the counting wheel 51 reaches the set value, that is, the push plate 35 on the first driving belt 34 pushes out the set number of articles 6 in the output direction, the driving shaft 21 stops rotating, and the article output mechanism stops outputting the articles 6, so that the article output mechanism can output the required number of articles 6.

As shown in fig. 2, fig. 3 and fig. 5, the article output mechanism in this embodiment further includes a positioning sensor 72 and a positioning wheel 71 mounted on the second driven shaft 42, a positioning sensing notch 711 is provided on the positioning wheel 71, and when the positioning sensing notch 711 of the positioning wheel 71 rotates to a position corresponding to the positioning sensor 72, the positioning sensor 72 can sense the positioning sensing notch 711. In the initial state, as shown in fig. 5, the positioning sensing notch 711 of the positioning wheel 71 corresponds to the position of the positioning sensor 72; when the second driven shaft 42 drives the counting wheel 51 to rotate, the positioning wheel 71 rotates synchronously with the counting wheel 51, and each time the positioning wheel 71 and the counting wheel 51 rotate completely for one circle, the positioning sensor 72 senses the positioning sensing notch 711 of the positioning wheel 71 again, and sequentially judges whether the positioning wheel 71, the counting wheel 51 and the first transmission belt 34 rotate to the proper position, and further judges whether the push plate 35 on the first transmission belt 34 pushes the article 6 out of the proper position. In this way, when the counting sensor 52 detects that the number of revolutions of the counting wheel 51 reaches the set value, and the positioning sensor 72 detects that the positioning wheel 71 rotates in place, that is, the push plate 35 on the first driving belt 34 pushes out the set number of articles 6 and pushes out the articles 6 to the set position, the driving shaft 21 of the first power unit 2 stops rotating, the article output mechanism stops outputting the articles 6, and the push plate 35 on the first driving belt 34 stops at the current position, so as to output the required number of articles 6 to the set position, and ensure that the push plate 35 stays at the set position at last.

In the present embodiment, the counting sensor 52 and the positioning sensor 72 are proximity switches. As shown in fig. 5, in the present embodiment, by using the sensing characteristic of the proximity switch, when the counting sensing notch 511 of the counting wheel 51 rotates along the circumferential direction of the second driven shaft 42 to the position corresponding to the counting sensor 52, the counting sensor 52 can sense the counting sensing notch 511; when the positioning sensing notch 711 of the positioning wheel 71 rotates to a position corresponding to the positioning sensor 72 along the circumferential direction of the second driven shaft 42, the positioning sensor 72 can sense the positioning sensing notch 711. The positioning sensor 72 and the counting sensor 52 described above may also be referred to as a photo eye. The positioning wheel 71 and the counting wheel 51 are both disc-shaped, and the positioning wheel 71 and the counting wheel 51 are distributed at intervals along the front-rear direction. Meanwhile, as shown in fig. 5, in the present embodiment, the counting sensing notch 511 and the positioning sensing notch 711 are distributed at intervals along the circumferential direction of the second driven shaft 42, so that the counting sensing notch 511 and the positioning sensing notch 711 are staggered along the circumferential direction of the second driven shaft 42, and the counting sensing notch 511 and the positioning sensing notch 711 are prevented from simultaneously corresponding to the counting sensor 52 and the positioning sensor 72, thereby causing mutual interference between the sensing capabilities of the counting sensor 52 and the positioning sensor 72. In the present embodiment, the counting sensing notch 511 and the positioning sensing notch 711 are staggered by an angle of 90 degrees in the circumferential direction of the second driven shaft 42.

As shown in fig. 1 to 4, the first power unit 2 in the present embodiment includes a motor 24 and a speed reducer 23 connected to the motor 24 through a clutch 22, and the driving shaft 21 is mounted on the speed reducer 23, i.e., the driving shaft 21 is an output shaft of the speed reducer 23.

When the first driving belt 34 drives the pushing plate 35 to move to a position corresponding to the to-be-output position of the article 6 and the in-place detection sensor 8 does not sense the article 6, it indicates that the corresponding article 6 does not move to the to-be-output position, at this time, the driving shaft 21 stops rotating, so that the first driving belt 34 and the pushing plate 35 stop moving until the in-place detection sensor 8 senses the corresponding article 6, it indicates that the article 6 has moved to the to-be-output position, the driving shaft 21 continues to rotate again, and drives the pushing plate 35 to move in the output direction and push out the article 6 in the output direction, thereby ensuring that the article output mechanism in this embodiment can smoothly output the article 6. Meanwhile, the in-position detection sensor 8 in this embodiment is a photoelectric switch.

In the embodiment, the two in-place detection sensors 8 are utilized, so that whether the article 6 is moved in place or not is effectively monitored more accurately. For example, as shown in fig. 4, if only one in-place detection sensor 8 senses the corresponding side of the article 6, and the other in-place detection sensor 8 does not sense the article 6, it indicates that the article 6 is not moved in place or moved in place in the set form, at this time, the article 6 may be inclined, and the like, the driving shaft 21 stops rotating, and the pushing plate 35 stops at the position corresponding to the position to be output, until the article 6 is corrected and moved in place in the set form, and the driving shaft 21 continues to rotate, and drives the pushing plate 35 to push out the article 6.

As shown in fig. 1 and 4, the push plate 35 of the present embodiment can push the article 6 to move in the left-right direction. In this embodiment, the conveyer belt 1 can drive the article 6 to move backward, and the push plate 35 can push the article 6 to move rightward, i.e. in the above-mentioned output direction. In this embodiment, the conveyer belt 1 is a belt conveyer, and the conveyer belt 1 includes a frame 11, a belt mounted on the frame 11, and a second power unit for driving the belt to rotate.

The two in-place detection sensors 8 are mounted at the rear end of the rack 11, one in-place detection sensor 8 is located above the position to be output, the other in-place detection sensor 8 is located on the left side of the position to be output, and when the article 6 moves to the position to be output in a normal form, as shown in fig. 1 and 2, the two in-place detection sensors 8 can respectively sense the upper surface and the left side surface of the article 6. The above-mentioned counting sensor 52 and the positioning sensor 72 are both mounted at the rear end of the frame 11, the counting sensor 52 and the positioning sensor 72 correspond to the above-mentioned counting wheel 51 and the positioning wheel 71, respectively, in the front-rear direction, and the counting sensor 52 and the positioning sensor 72 are located at the same height. In addition, in the present embodiment, the first transmission belt 34 and the second transmission belt 44 are both belts.

As shown in fig. 1, the push plate 35 in this embodiment has a plurality of push plates 35, and all the push plates 35 are spaced apart in the circumferential direction of the first belt 34. In this way, during one rotation of the first conveyor belt 34, the push plates 35 push the articles 6 on the conveyor belt 1 one by one to the right. In this embodiment, the first driving belt 34 is specifically provided with 3 push plates 35, and the 3 push plates 35 are a first push plate 351, a second push plate 352, and a third push plate 353, respectively. In the process of one rotation of the first conveyor belt 34, the 3 pushing plates 35 push out the 3 articles 6 on the conveyor belt 1 one by one to the right. In an initial state, as shown in fig. 1, the first pushing plate 351 is located at the left side of the to-be-output position, and when the first belt 34 is operated, the first pushing plate 351 will first push the article 6 located at the to-be-output position to the right.

As shown in fig. 1, fig. 2 and fig. 4, a rollgang 9 is provided on the right side of the rear end of the conveyor belt 1 in this embodiment, that is, the rollgang 9 is located on the right side of the position to be output.
