When a worker opens the rotating door 151 and takes the section bars off the rest 15, the section bars are required to be sequentially placed on the first conveying belt 11; when the profile moved onto the second conveyor belt 12 reaches a certain length, the pressing device 13 will press the profile and the cutting device 14 will cut the profile from the space between the first conveyor belt 11 and the second conveyor belt 12, thereby completing the cutting process of the profile.
However, the sectional materials on the shelf 15 are placed on the first conveyor belt 11, which requires a worker to manually complete the process, and since tens or even hundreds of sectional materials are generally placed on the shelf 15, and most of the sectional materials have a length of 2 meters to 4 meters, the worker usually needs to complete the process of taking and placing the sectional materials by two persons, which is inconvenient, high in labor intensity, low in work efficiency, and thus needs to be improved.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide an automatic section feeding mechanism, which realizes full-automatic section feeding and improves the section feeding efficiency.
The above object of the present invention is achieved by the following technical solutions: an automatic profile feeding mechanism comprises a placing frame for stacking profiles and a conveying device for conveying the profiles to a cutting device, wherein a side opening for taking and placing the profiles is formed in one side of the placing frame; the rack is provided with a blocking assembly for blocking the profile at the side opening and a driving device for driving the blocking assembly to move downwards, and the top of the blocking assembly is provided with a guiding device for guiding the profile to the conveying device in sequence.
By adopting the technical scheme, in the process of feeding the section bars, the placing rack is driven by the rotating piece to rotate so that the side opening is inclined downwards, and then the blocking component is driven by the driving device to move downwards, so that the blocking component cancels the blocking of the uppermost section bar; therefore, the placing rack is in an inclined state, so that the section bar at the uppermost layer obliquely slides downwards to the side opening and is sequentially guided to the conveying device by the guide device, and the conveying device conveys the section bar to the cutting device for cutting.
After the uppermost layer of section bars are separated from the placing rack, the driving device drives the blocking assembly to move downwards, so that the blocking assembly cancels the blocking of the second layer of section bars; the section bar on the second floor will incline and slide to side mouth department and be guided to conveyor by guider this moment on, repeat this process, can all the direction of all section bars on the rack are carried to conveyor on, have realized the full-automatic material loading of section bar to the material loading efficiency of section bar has been improved.
The present invention in a preferred example may be further configured to: the stop assembly comprises two groups of stop rods used for supporting the section bars at the side openings, one end of each stop rod is provided with a vertical sliding block, and each vertical sliding block is connected to the placing frame in a sliding mode along the vertical direction.
Through adopting above-mentioned technical scheme, because of the setting of vertical slider for block the pole and only can follow vertical direction motion, thereby guaranteed to block the effect that blocks of pole offside department section bar.
The present invention in a preferred example may be further configured to: the driving device comprises two groups of horizontal sliding blocks, a bidirectional screw rod and a servo motor; the two groups of blocking rods form a V-shaped rod together, and each vertical sliding block is rotatably connected to the upper end of the corresponding blocking rod; the lower end of each blocking rod is rotatably connected to a horizontal sliding block, two groups of horizontal sliding blocks are connected to the placing rack in a sliding mode along the horizontal direction, threaded through grooves in threaded fit with the two-way screw rods are formed in the two groups of horizontal sliding blocks, and the rotating directions of the two groups of threaded through grooves are opposite; the two-way lead screw extends along the horizontal direction and is fixedly connected to an output shaft of the servo motor, and the servo motor is fixed on the placing frame.
Through adopting above-mentioned technical scheme, when servo motor drove two-way lead screw and rotates, because of the rotation to opposite of two sets of screw thread logical groove, and have two sections to opposite screw thread section on the two-way lead screw soon, so two sets of horizontal slider will be close to each other for block the pole and take place to rotate, and make vertical slider lapse, block the pole this moment and will cancel stopping to the superiors' section bar, thereby be convenient for the full-automatic unloading of section bar.
Simultaneously, at the material loading in-process of section bar, because of two sets of stop the pole all be rotary motion, so after the equal material loading of section bar on the rack is accomplished, two sets of stop the pole and will be accomodate on the rack, and stop the upper end of pole and do not outstanding in the lateral part of rack, stop the lower extreme of pole and do not outstanding in the lower part of rack, so reduced the rack and blockked the whole occupation space of subassembly to make stop the pole and be difficult for stumbling the workman.
The present invention in a preferred example may be further configured to: the guide device comprises a first inclined rack arranged on the two groups of vertical sliding blocks and a second inclined rack connected to the first inclined rack in a rotating mode, the upper surface of the first inclined rack is parallel to the upper surface of the placing rack, and the lower end of the second inclined rack is far away from the placing rack and placed on the conveying device.
By adopting the technical scheme, when the blocking rod cancels the blocking of the uppermost layer section bar, the section bar slides to the side opening obliquely and downwards; the upper surface of the first inclined frame is parallel to the upper surface of the placing frame, so that the sectional material can stably move onto the first inclined frame; the profile will then slide onto the second tilting frame and onto the conveyor in the direction of the tilt of the second tilting frame for subsequent cutting machining of the profile.

Then, the driving motor 682 drives one of the rotating rods 644 to rotate, and under the action of the belt 681, all the rotating rods 644 synchronously rotate in the same direction, so that the roller 645 can drive the uppermost section to obliquely slide downwards and sequentially pass through the first inclined rack 61 and the second inclined rack 62; the profile of the first group will then move onto the first conveyor belt 31 and abut against the stop 625, which will block the subsequent profile until it moves free from the subsequent profile, thus achieving the sequential feeding of the profiles.
Then, the profile is conveyed to the second conveyor belt 32 in an inclined state, the profile passes through the notch 333 and partially moves to the third conveyor belt 33 under the action of the second conveyor belt 32, and then the profile gradually rotates to the third conveyor belt 33 and enters the channel; under the action of the third conveyor belt 33, the profile is conveyed onto the fourth conveyor belt 34, and when the profile on the fourth conveyor belt 34 reaches a certain length, the profile is pressed by the pressing device 13, and the profile is cut off from the space between the third conveyor belt 33 and the fourth conveyor belt 34 by the cutting device 14, so that the cutting process of the profile is completed.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
