Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the following describes the conveying mechanism provided by the present invention in detail with reference to the attached drawings.
Referring to fig. 2, a conveying mechanism according to an embodiment of the present invention includes a conveying rail for carrying and conveying a conveyed member. Specifically, the conveying rail includes a plurality of rotating shafts 4 arranged at intervals in the conveying direction of the conveyed member, and a plurality of rollers 5 arranged at intervals in the axial direction of the rotating shafts 4 are provided on each rotating shaft 4. The outer peripheral surface of the roller 5 is a contact surface 51 that comes into contact with a conveyed member during conveyance.
Also, a fluid passage having an adsorption port 7, a fluid inlet 9, and a fluid outlet 8 is provided in the transfer rail, wherein the adsorption port 7 is located on the contact surface 51. Fluid enters the fluid channel via the fluid inlet 9 and exits via the fluid outlet 8; and the fluid outlet 8 is communicated with the adsorption port 7 for generating negative pressure at the adsorption port 7 to adsorb the transferred member when the fluid flows out through the fluid outlet 8.
According to the bernoulli principle: at equal height flows, the greater the flow rate, the lower the pressure. And, the pressure at a point in the fluid satisfies the following equation:
P1+1/2ρv1 2+ρgh1＝P2+1/2ρv2 2+ρgh2
wherein, P1Is the pressure of the fluid at the location of the fluid outlet 8; p2The pressure of the fluid at the position of the adsorption port 7; v. of1And v2The flow rates of the fluid at the two positions are respectively; ρ is the fluid density; g is the acceleration of gravity; h is1And h2The heights at the two positions are respectively.
The height is negligible and the flow rate of the fluid at the position of the adsorption port 7 is 0, so the above formula can be simplified as follows:
P1＝P2-1/2ρv1 2
the pressure at the position of the adsorption port 7 is the transfer environment pressure, and as can be seen from the above formula, P1< ambient pressure of delivery. Therefore, negative pressure is generated at the position of the suction port 7, so that the conveyed member can be sucked on the contact surface 51, and the conveyed member is prevented from slipping. Meanwhile, the conveying mechanism provided by the invention can be suitable for various fluid environments by utilizing the Bernoulli principle to vacuum-adsorb the conveyed piece, so that the pollution problem of a vacuum pipeline is avoided.
In addition, compared with the prior art, the conveying mechanism provided by the invention does not need to press the conveyed piece by means of the upper track, so that the occupied space is smaller, and the conveyed piece is not easy to damage.
In the present embodiment, as shown in fig. 3 and 4, the suction ports 7 are plural and are distributed at intervals in the circumferential direction of the roller 5. The fluid outlet 8 is provided in plurality, and each two fluid outlets 8 are respectively positioned on two side surfaces 52 of the roller 5 adjacent to the contact surface 51 and are communicated with one adsorption port 7. When the rotating shaft 4 drives the roller 5 to rotate, the roller 5 drives the conveyed piece to move, meanwhile, the plurality of adsorption ports 7 on the roller 5 rotate one by one to the bottom of the conveyed piece and adsorb the conveyed piece, and therefore the conveyed piece can be adsorbed continuously.
As shown in fig. 5, since the contour of the roller 5 is circular, the conveyed member can be sucked when the roller 5 rotates to a position where a certain suction port 7 is opposite to the conveyed member; when the roller 5 continues to rotate, the round roller is convenient for separating the conveyed piece from the roller 5, so that the conveyed piece can normally travel.
Optionally, the angle between the orientation of each fluid outlet 8 and the orientation of the adsorption port 7 communicating therewith is less than 90 °. Preferably, as shown in fig. 3, the angle is 45 °, which can reduce the flow rate at the fluid outlet 8 and increase the negative pressure generated at the adsorption port 7, thereby increasing the adsorption force.
Alternatively, as shown in fig. 4, in two adjacent rollers 5, when any one suction port B of one roller 5 faces the conveyed member, the interval a between any two adjacent suction ports of the other roller 5 faces the conveyed member. Thus, if one roller 5 cannot suck the conveyed member because the gap a faces the conveyed member, the suction port B of the adjacent roller 5 faces the conveyed member, so that the conveyed member can be sucked.
In addition, in practical application, the stability of adsorbing the conveyed object can be improved by increasing the number of the adsorption ports 7 and reducing the interval a. Optionally, an included angle between the orientations of any two adjacent adsorption ports 7 on each rotating shaft 4 is greater than 0 ° and less than or equal to 45 °. The range of the included angle can be obtained to make the number of the adsorption ports 7 meet the requirement.
In the present embodiment, the fluid passage includes an axial passage 10 and a branch passage, wherein the axial passage 10 is provided in the rotating shaft 4 and penetrates the rotating shaft 4 in the axial direction of the rotating shaft 4; and, the fluid inlet 9 is located at one end of the axial channel 10, and the other end of the axial channel 10 is a fluid discharge port 11 for discharging excess fluid in the axial channel 10. Of course, the fluid discharge port 11 may not be provided, and the axial passage 10 may not penetrate the other end of the rotating shaft 4.
One of the above-described branch passages is provided in each roller 5, and each branch passage communicates the axial passage 10, the fluid outlet 8, and the suction port 7. Specifically, in the present embodiment, each branch channel includes a radial branch 12, an outlet branch 13, and an adsorption branch 14, wherein one end of the two outlet branches 13 serves as two fluid outlets 8 corresponding to each adsorption port 7, and the other ends of the two outlet branches 13 are both communicated with one end of the radial branch 12; the radial branch 12 is arranged along the radial direction of the rotating shaft 4, and the other end of the radial branch 12 is communicated with the axial channel 10, so that the axial channel 10, the fluid outlet 8 and the adsorption port 7 are communicated.
The adsorption branch 14 includes a first branch and two second branches, wherein one end of the first branch serves as the adsorption port 7; one end of each of the two second branches is communicated with the other end of the first branch, and the other ends of the two second branches are respectively communicated with the two outlet branches 13.
When conveying the conveyed member, the fluid enters the axial channel 10 via the fluid inlet 9 and flows out through the radial branch 12 and the two outlet branches 13 in sequence.
Optionally, the inner diameter of the radial branch 12 is larger than the inner diameter of the outlet branch 13; the outlet branch 13 has an inner diameter larger than that of the adsorption branch 14.
In practice, the fluid comprises a gas or a liquid. The gas may be dry air or the like. The liquid may be a medicinal liquid or the like.
In the present embodiment, the conveying rails are the rotating shaft and the roller, but the present invention is not limited to this, and in practical application, other conveying rails with any structure may be adopted as long as the fluid channel can be applied.
The invention provides a conveying mechanism, which is provided with a fluid channel in a conveying track, wherein the fluid channel is provided with an adsorption port, a fluid inlet and a fluid outlet, and the adsorption port is positioned on a contact surface. Fluid enters the fluid channel through the fluid inlet and flows out through the fluid outlet; and the fluid outlet is communicated with the adsorption port and is used for generating negative pressure at the adsorption port when the fluid flows out through the fluid outlet so as to adsorb the conveyed piece. Since the suction port can suck the conveyed member, the conveyed member can be prevented from slipping during conveying. Meanwhile, compared with the prior art, the conveying mechanism provided by the invention does not need to press the conveyed piece by means of the upper track, so that the occupied space is smaller, and the conveyed piece is not easy to damage.
