Description

Technical Field

The first-in-last-out disc conveying equipment generally consists of a tray loading machine, a tray unloading machine and a large-flow conveying channel. When the rod-shaped materials are loaded into or unloaded from the disc conveying equipment, the rod-shaped materials often appear in a disordered arrangement, or the ends or appearance are damaged; the first-in-first-out disc conveying equipment includes a conveying channel and a disc station, which causes less damage to the rod-shaped materials, but has the disadvantage of occupying a large area; the discless conveying equipment is composed of a storage device and a conveying channel, and also has two modes: first-in-first-out and first-in-last-out. The first-in-last-out storage device has the disadvantages of long storage time of rod-shaped materials and difficult traceability of production quality of rod-shaped materials, and there are quality risks; the first-in-first-out disc conveying equipment mainly stores (or discharges) rod-shaped materials by increasing (or reducing) the conveying channel, and there is a risk of damage to the rod-shaped materials.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0035] Example

[0036] like Figure 1 As shown, the vertical rod-shaped material conveying and caching device is a node device of the rod-shaped material conveying equipment, and is located in the middle position of the rod-shaped material conveying equipment. The device includes a fixed support unit 1, a rotating unit 2, a vertical storage and conveying unit 3, a horizontal conveying unit 4 and an electric control system;

[0037] The rotating unit 2 is installed inside the fixed support unit 1, and the driving device of the rotating unit 2 is fixedly installed on the fixed support unit 1. The top of the fixed support unit 1 is provided with a rod-shaped material inlet, the vertical storage and conveying unit 3 is fixedly arranged on the upper part of the rotating unit 2, and the horizontal conveying unit 4 is fixedly arranged at the lower part of the fixed support unit 1 to receive the rod-shaped material conveyed by the vertical storage and conveying unit 3, and the rod-shaped material enters the vertical storage and conveying unit 3 through the rod-shaped material inlet. The bottom of the fixed support unit 1 is provided with a rod-shaped material output port, and the rod-shaped material output port is connected to the horizontal conveying unit 4 to receive the rod-shaped material from the horizontal conveying unit 4. The electric control system is connected to the fixed support unit 1, the rotating unit 2, the vertical storage and conveying unit 3 and the horizontal conveying unit 4;

[0038] The fixed support unit 1 is a cylindrical box;

[0039] The vertical storage and conveying unit 3 includes a plurality of vertical storage and conveying units arranged in a circular array on the upper part of the rotating unit 2;

[0040] The vertical storage and conveying unit 3 is arranged vertically.

[0041] In the above embodiment, the rod-shaped material enters the downstream equipment through the rod-shaped material output port; and the vertical rod-shaped material conveying and buffering device obtains the rod-shaped material conveyed by the upstream equipment through the rod-shaped material inlet.

[0042] In the above embodiment, the electric control system includes an electric control cabinet, a control system, and a servo system. The control system is installed in the electric control cabinet. The control system is composed of an industrial control machine with a display, which is used for program control, human-machine interface operation, and data storage. The servo system includes a power module and a servo controller, which are used to drive the servo motors of the rotating unit 2, the vertical storage and conveying unit 3, and the horizontal conveying unit 4.

[0043] like Figure 4 As shown, the vertical storage and transportation unit includes a storage cavity tube 31 and a bracket device 32 and a baffle 33 arranged in the storage cavity tube 31. The bracket device 32 is driven by a linear motion unit 34 driven by a servo motor to move up and down in the storage cavity tube 31, and the baffle 33 is fixedly mounted on the bracket device 32;

[0044] In the above embodiment, the bracket device 32 is driven by the linear motion unit 34 to move downward to achieve the storage of rod-shaped materials. When the materials are released, the connecting rod is driven by the cylinder to open the baffles on both sides of the bracket device 32 to discharge the rod-shaped materials.

[0045] like Figure 2As shown, the fixed support unit 1 includes a disc base 11, a plurality of support columns 12, a plurality of glass shields 13 and a fixed top plate 14, wherein the plurality of support columns 12 are fixedly arranged between the disc base 11 and the fixed top plate 14, and the glass shield 13 is arranged between adjacent support columns 12 to close the fixed support unit 1;

[0046] In the above embodiment, in order to facilitate the opening of the glass cover 13, the glass cover 13 is installed on the supporting column 12 through a hinge;

[0047] The rod-shaped material outlet is provided on the disc base 11;

[0048] The rod-shaped material interface is arranged on the fixed top plate 14 .

[0049] like Figure 3 As shown, the rotating unit 2 includes a slewing support bearing 21, a rotating cylinder 22, a rotating servo motor 23 and a driving gear 24. The inner ring of the slewing support bearing 21 is fixedly arranged at the bottom of the fixed support unit 1, the rotating cylinder 22 is fixedly arranged at the outer ring of the slewing support bearing 21, the driving gear 24 is meshed with the outer ring of the slewing support bearing 21, and the rotating servo motor 23 is connected to the driving gear 24.

[0050] like Figure 5 As shown, the horizontal conveying unit 4 includes a bracket 41, a profile 42, a horizontal servo motor 43, a sprocket 44 and a chain plate 45. The sprocket 44 and the chain plate 45 are installed on the profile 42. The sprocket is driven by the horizontal servo motor 43 to drive the chain plate 45 to slide on the profile 42, thereby realizing the horizontal conveying of the rod-shaped material. The bracket 41 is used to fix the profile 42 at the bottom of the fixed support unit 1;

[0051] The profile 42 is provided with an output end, and the output end is connected to an arc-shaped guide plate 46 , and the arc-shaped guide plate 46 is used to guide the falling of the rod-shaped material.

[0052] The electronic control system controls the servo motor that drives the rotating unit 2 to rotate precisely, thereby realizing the precise displacement of the storage cavity tube of the vertical storage and conveying unit 3; controls the servo motor of the linear motion unit to drive the bracket device 32 of the vertical storage and conveying unit 3 to move up and down smoothly; drives the servo motor on the horizontal conveying unit 4 to rotate, thereby driving the chain plate to convey the rod-shaped material to the rod-shaped material output port.

[0053] During specific use, the rod-shaped materials produced by the upstream machine enter the vertical rod-shaped material conveying and buffering device through the rod-shaped material entrance on the fixed top plate 14, and are directly conveyed through the channel of the vertical rod-shaped material conveying and buffering device or conveyed to the downstream machine after being buffered, thereby ensuring the stability of the production of the upstream and downstream machines.

[0054] When booting, if Figure 6 As shown, the shadow shows the rod-shaped material. The rod-shaped material passes through the conveying device and enters the vertical rod-shaped material conveying buffer device. The photoelectric switch at the entrance of the vertical storage and conveying unit is activated. At this time, the bracket device 32 corresponding to the rod-shaped material input channel is at the top position in the vertical storage and conveying unit. The electronic control system controls the servo motor of the linear motion unit to drive the bracket device 32 to smoothly convey the rod-shaped material to the lower part of the storage cavity tube 31; the baffles on both sides of the bracket device 32 are opened, and the rod-shaped material enters the outlet guide plate of the horizontal conveying unit 4 under the action of gravity, and is then conveyed to the downstream machine by the downstream interface. At this time, the upstream and downstream machines work normally (upstream and downstream speeds match).

[0055] like Figure 7 As shown, the direction of the arrow indicates the flow direction of the rod-shaped material. When the downstream machine fails and stops, the vertical rod-shaped material conveying and caching device will enter the material storage state. At this time, the upstream conveying channel of the vertical rod-shaped material conveying and caching device is closed (the rod-shaped material does not enter the vertical rod-shaped material conveying and caching device), and the baffles on both sides of the bracket device in the vertical storage and conveying unit are closed upward, and the linear motion unit lifts the bracket device to the top; the upstream conveying channel of the vertical rod-shaped material conveying and caching device is opened, and the rod-shaped material descends with the bracket device 32 to fill the storage cavity tube 31; the electric control system closes the upstream conveying channel, and the electric control system rotates the rotating unit 2 clockwise to turn the next empty vertical storage and conveying monomer to the position of the rod-shaped material entrance, and the upstream conveying channel is opened. Under the guidance of the bracket device, the rod-shaped material gradually fills the vertical storage and conveying monomer. The unit stops until the vertical storage and conveying units of the vertical rod-shaped material conveying and caching device are filled to a limited position (for example, when the filled vertical storage and conveying units account for 5 / 6 of the entire vertical storage and conveying units, it can be set on the human-machine interface).

[0056] like Figure 8As shown, when the downstream machine fails and stops for a period of time, and then resumes normal operation, a part of the vertical storage and conveying monomers are filled. In order to ensure the first-in-first-out function of the vertical rod-shaped material conveying cache device, it is necessary to fill the vertical storage and conveying monomers of the vertical rod-shaped material conveying cache device until the vertical storage and conveying monomers filled with rod-shaped materials are rotated to the limited position of the vertical rod-shaped material conveying cache device. Then, the vertical storage and conveying monomers will be filled while being emptied at the limited position of the device. The electrical control system of the vertical rod-shaped material conveying cache device can save the limited position of the filled vertical storage and conveying monomers (which can be set on the human-machine interface), which can ensure that the vertical storage and conveying monomers are emptied here. After the rod-shaped materials are discharged from the storage cavity tube 31, they are transported to the downstream machine interface by the chain plate on the horizontal conveying unit.

[0057] When the downstream machine fails and stops for a period of time, and then resumes normal operation, a part of the vertical storage and conveying units are filled. In order to ensure the first-in-first-out function of the vertical rod-shaped material conveying buffer device, the following operation method can also be adopted: stop the upstream machine, set the vertical rod-shaped material conveying buffer device to manual emptying mode, and the electronic control system controls the rotation of the rotating unit to rotate the vertical storage and conveying unit that first stores the rod-shaped material to the rod-shaped material output port to discharge the rod-shaped material, and then discharge the rod-shaped material from other units in order according to the filling order, restore the vertical rod-shaped material conveying buffer device to a fully empty state, and then restart the machine.

[0058] like Fig. 9 As shown, the angle between the storage cavity tube 31 and the horizontal direction is 60°-120°. In addition to being set vertically, the storage cavity tube 31 can also be set at an angle A with the horizontal direction, and the value of A is: 120°≥A≥60°. Compared with the vertically arranged storage cavity tube 31, the linear motion unit in the obliquely arranged storage cavity tube 31 is arranged obliquely, and its length is longer than that of the vertically arranged linear motion unit. The bracket and opening device structure are the same as those of the vertical arrangement.

[0059] The present invention is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention may be subject to various changes and improvements, which are within the scope of the present invention to be protected.
