The contact pressure of the contact surface 23 of the touch slide plate and the outer circular surface of the touch wheel 16 is maximum when the limit groove A of the driving plate 12 is aligned with the inlet of the conveyed circular object, so that the hook 14 is fully opened, the upper and lower surfaces of the touch slide plate 11 do not exceed the upper and lower surfaces of the pressure control wheel, and interference with the pinch roller 15 is avoided. The touch wheel 16 is contacted with the touch slide plate 11 when moving to the inlet position of the conveyed round object 4, and the hook 14 integrated with the touch wheel 16 is forced to stretch a large angle to give way to the conveyed round object 4.
In order to make the contact wheel 16 and the contact slide 11 cooperate smoothly in motion to avoid impact, the contact slide 11 has a sufficient length and the contact surface 23 of the contact slide 11 has a certain circular arc, and the contact slide 11 is mounted at a proper angle, so that the contact wheel 16 contacts with the contact wheel earlier, the hook 14 and the pinch roller 15 are gradually opened along with the rotation of the dial 12, and the maximum opening angle is reached when the dial 12 stops.

As shown in fig. 9, the output mechanism mainly includes a conveyor belt 1, a guide roller 8, and a guide plate 9. The conveyer belt 1 and the input mechanism adopt the same conveyer belt. The guiding-out roller 8 and the guiding-out plate 9 are assembled above the conveyer belt 1, a conveying channel formed between the guiding-out roller 8 and the guiding-out plate 9 is aligned with a limit groove of the material level of the driving plate 12, and a guiding circular arc surface 24 of the guiding-out plate 9 is coaxial with the guiding-out roller 8 and respectively inscribes and circumscribes the excircle of the conveyed circular object 4. The direction of rotation of the lead-out roller 8 is opposite to the direction of rotation of the dial 12.
In the direction perpendicular to the surface of the driving plate 12, the mounting height of the guiding-out plate 9 and the guiding-out roller 8 need to avoid the hook 14 (comprising the lever arm 14.1, the swinging arm 14.2 and the touch arm 14.3), the pinch roller 15, the touch wheel 16, the first leaning wheel 17, the second leaning wheel 6 and the like so as to avoid interference, and the application point of the circular object 4 to be conveyed needs to ensure stable operation.
The rotation drive assembly 7 is mounted on the side of the dial 12. The friction wheel 5 of the rotation driving assembly 7 is used for driving the conveyed round object 4 to rotate.
The workflow of the single-dial guardrail-free conveying device of the embodiment is as follows:
the driving plate 12 moves intermittently clockwise, and when the driving plate is stopped, the conveying belt 1, the spiral guide rail 2 and the spiral guide rail guard rail 3 cooperate to convey the conveyed round object 4 to the limit groove A of the driving plate 12. Simultaneously, the touch wheel 16 swings anticlockwise to open the hook 14 and the pinch roller 15 under the extrusion of the touch slide plate 11, so that a channel for conveying a round object is opened.
When the driving plate 12 starts one cycle of operation, after the driving plate 12 rotates by a proper angle, the touch wheel 16 is separated from the constraint of the touch slide plate 11, the hook 14 is reset under the tension of the tension spring, and the pinch roller 15 presses the conveyed round object 4, so that the driving plate 12 is gradually carried to the limit groove G. Various operations can be performed on the conveyed round object 4 during the stepwise conveyance, such as being driven to rotate by the rotation driving unit 7 and being scanned for photographing.
At the groove G of the driving plate 12, the conveyed round object 4 overcomes the tension of the tension spring 13 under the action of the friction force of the outer circular surface of the guiding-out roller 8 which continuously rotates anticlockwise, so that the hook 4 is promoted to open and conveyed out along the circular arc surface of the guiding-out plate 9.
