The split direction of the split bar is the specified direction;

The feeding mechanism 4 transfers the split bars from the storage mechanism 2 to the machining equipment one by one. The feeding mechanism includes a feeding manipulator 41 and a second drive assembly that drives the feeding manipulator 41 to move;

Wherein, when the distributing manipulator 31 of the distributing mechanism 3 grabs the divided bar stock on the product placement table 11 of the feeding mechanism 1, the divided head sensor of the material distributing mechanism 3 detects the divided head direction of the divided bar stock, if the divided head direction is designated Orientation, the material distribution manipulator 31 directly puts the split bar into the bin 21 of the material storage mechanism 2; if the direction of the split head is opposite to the specified direction, the rotating cylinder 32 of the material distribution mechanism 3 first drives the material distribution manipulator 31 to rotate to make The split head of the split bar is put into the feed bin 21 after the designated direction;

After the split bars are put into the bin 21, the push rod assembly 22 of the material storage mechanism 2 pushes the split bars to be neatly stacked, and at the same time, the ejector assembly 23 pushes the split bars upward one by one, and the pushed split bars pass through the feeding The feeding manipulator 41 of mechanism 4 grabs and then transfers to the machining equipment.

On the product placement table 11, the clamping assemblies 12 arranged on both sides of the product placement table 11 clamp the split bar and wait for the grabbing of the distribution manipulator 31 of the distribution mechanism 3. The clamping assembly 12 in the embodiment of the present invention includes a clamping plate 121 and a first driving cylinder 122 for driving the clamping plate 121 to clamp the split bar. Specifically, a material induction detection device (not shown in the figure) is provided on the product placement platform 11. The material induction detection device is used to detect whether the product placement platform 11 is a qualified material, that is, it is not a defective material or a broken material. When it is a qualified material, the first drive cylinders 122 located on both sides of the product placement table 11 drive the corresponding clamping plate 121 relatively close to the split bar and clamp and fix it. When an unqualified product is detected, the material distribution manipulator 3 does not act.

Referring to Figures 3 to 4, the bin 21 in the embodiment of the present invention is used to store a certain number of split bars with a specified split direction, and at the same time, it has the function of pushing and sorting the split bars to prevent them from tilting during the rolling process and causing jamming. problems, as well as the function of automatically taking out individual bars from the stockpile and discharging them one by one in an orderly manner. The top of the feed bin 21 in the embodiment of the present invention is open, and the slope top of the feed bin 21 is provided with two chutes 211 along the inclination direction of its bottom surface. The two chutes 211 are parallel to each other and arranged at intervals. The spacing corresponds to the axial length of the major diameter of the split bar stock. Wherein, the push rod assembly 22 includes a push rod 221 slidingly matched with the chute 211 , a second drive cylinder 222 for driving the push rod 221 to reciprocate along the chute 211 , and a third drive cylinder 223 for driving the push rod 221 up and down.

Specifically, when the distributing manipulator 31 grabs the split bar on the feeding mechanism 1 and puts it into the bin 21, the split bar starts to roll close to the bottom of the bin 21 by its own weight, and the second driving cylinder 222 drives the push rod 22 at the same time. Move along the chute 211 and press the split bars, so that the axes of the split bars in the feed bin are all in a parallel state, without tilting, and prevent jamming. At the same time, since the bottom of the material bin 21 has a certain slope, the push rod 221 is driven up and down by the third driving cylinder 223 to adapt to the slope of the bottom of the material bin 21 . In order to make the push rod 221 fit the split bar stock better, a profiling arc surface is provided on the contact surface of the push rod 221 and the split bar stock.

In the initial state, the upper end surface of the ejector plate 231 is on the same level as the bottom surface of the silo 21. When the fourth driving cylinder 233 drives the ejector plate 231 to rise, the upper end of the ejector plate 231 will separate the bar from the silo 21. The bottom is pushed up and rises. During the ascent, the split bar stock far away from the upper end surface of the top plate 231 falls back to the feed bin 21 due to its own weight, so as to ensure that the top stock plate 231 only pushes out one split bar stock at a time.

Further, the upper end surface of the top material plate 231 has a first inclined surface 2311 inclined downward toward the direction of the material baffle plate 232, and the upper end surface of the material baffle plate 232 has a second inclined surface 2321 inclined downward toward the direction of the top material plate 231. The inclined surface 2311 and the second inclined surface 2321 form a V-shaped material trough 234 for carrying the split bar. The depth of the V-shaped material groove 234 matches the major diameter of the split bar. In order to ensure that 231 only pushes out one split bar at a time, the thickness of the ejector plate 231 is kept consistent with the major diameter of the split bar, so as to ensure that the split bar at the upper end of the ejector plate 231 is kept away from the upper end of the ejector plate 231 Material falls back in the feed bin 21 again. Simultaneously, the ejecting process of the ejector plate 231 is also to guide the activities of the accumulated sub-bars in the feed bin 21, so as to facilitate the arrangement and accumulation of the sub-bars in the feed bin 21.

Referring to FIG. 5 , the distributing manipulator 31 of the embodiment of the present invention can transfer the split bars one by one from the feeding mechanism 1 to the bin 21 , and has the function of adjusting the split direction of the split bars.

Specifically, the fifth drive cylinder 32 drives the material distribution manipulator 31 to move laterally to directly above the product placement table 11, and the sixth drive cylinder 33 drives the material distribution manipulator 31 to lower the material distribution gripper 3111 to grab the food placed on the product placement table 11. After splitting the bar stock, the sixth driving cylinder 33 drives the splitting manipulator 31 to rise, and the split head sensor detects that the split head of the split bar stock grabbed by the splitting jaw 3111 is the specified orientation, and directly puts the grabbed split bar stock into the In the material bin 21, if the direction of the split head is not the designated direction, the rotating cylinder 34 drives the distributing jaw 3111 to rotate 180° with its axis, and after adjusting the split head bar to the designated direction, the fifth driving cylinder 32 drives the distributing manipulator 31 to move laterally To the top of the feed bin 21, the material distribution jaw 3111 releases the split bar to make it fall into the feed bin 21.

The eighth driving cylinder 43 used to drive the feeding manipulator 41 up and down. Specifically, the upper end of the top plate 231 pushes up the split bar from the bottom of the bin 21 so that the split bar is placed behind the V-shaped trough 234 formed by the top plate 231 and the baffle plate 232, and the seventh drive The cylinder 42 drives the feeding manipulator 41 to move laterally to the top of the V-shaped trough 234, and the eighth drive cylinder 43 drives the feeding manipulator 41 to lower the feeding jaw 4111 to grab the separate bar on the V-shaped trough 234 Drive the second mechanical arm 41 to rise again, and at the same time, the seventh driving cylinder 42 drives the feeding manipulator 41 to move laterally to the back-end machining equipment, providing the back-end machining equipment with separate bars with specified head orientations, which is convenient for production and processing and improves processing. Efficiency; at the same time, the split bars used by the back-end machining equipment come from the silo 21. Therefore, even if there are unqualified parts at the front end of the feeding mechanism 1, it will not cause the back-end machining equipment to stop due to lack of material, so that the production will continue .
