[0039] As attached Figure 1 -Attached Figure 6As shown, the utility model provides a bar feeding device, which is suitable for feeding bars 10 of various cross-sections and various materials. In specific use, multiple bars 10 are initially stacked and placed parallel to each other. For example, the bundled bars are directly untied from the ropes in the hopper 11, and then the multiple bars 10 are fed one by one along a specific path through the bar feeding device, and the bar 10 is transported to the next station for processing.

[0040] The bar material feeding device includes a hopper 11 and a bar material conveying mechanism 12, wherein the hopper 11 is used to hold a plurality of bar materials 10 to be fed, and the bar material conveying mechanism 12 is used to convey the bar materials 10 one by one to the next station;

[0041] The bar material conveying mechanism 12 comprises a conveying track 121 and a pushing mechanism 122. One end of the conveying track 121 is a pushing end 1211, and the other end is a pushing end 1212. The output end of the pushing mechanism 122 reciprocates from the pushing end 1211 to the pushing end 1212. When the output end of the pushing mechanism 122 moves toward the pushing end 1212, the output end of the pushing mechanism 122 pushes the bar material 10 located in the conveying track 121 out of the pushing end 1212, so that the bar material 10 enters the next station. When the output end of the pushing mechanism 122 moves toward the pushing end 1211, the output end of the pushing mechanism 122 exits the conveying track 121, so that the next bar material 10 enters the conveying track 121 for the next pushing.

[0042] A feeding chute 118 is provided at the bottom of the hopper 11 , and the feeding chute 118 is aligned with the conveying track 121 , so that a plurality of bars 10 in the hopper 11 fall into the conveying track 121 one by one through the feeding chute 118 , thereby realizing the one-by-one loading of the bars 10 .

[0043] The utility model provides a bar loading device, in which multiple bars 10 to be loaded only need to be stacked in the same direction in the hopper 11, and the multiple bars 10 in the hopper 11 fall into the conveying track 121 one by one, and then the pushing mechanism 122 conveys the single bars 10 on the conveying track 121 to the next station one by one, thereby completing the loading of the bars 10. The bars 10 move under the guidance of the conveying track 121 and can enter the next station accurately and quickly, with good loading effect and high efficiency, and the overall structure of the bar loading device is simple and reliable.

[0044] In one embodiment, the hopper 11 includes a high vertical plate 111, an inclined plate 112, a low vertical plate 113 and two side plates 114 arranged opposite to each other. The high vertical plate 111, the inclined plate 112, the low vertical plate 113 and the two side plates 114 enclose the hopper 11, and the inner sides of the high vertical plate 111, the inclined plate 112, the low vertical plate 113 and the two side plates 114 enclose a hopper cavity.

[0045] The high upright plate 111 and the low upright plate 113 are arranged opposite to each other and enclose the blanking trough 118. The width of the blanking trough 118 is preferably larger than the cross-sectional size of one bar 10 and smaller than the cross-sectional size of two bars 10, that is, only one blanking trough 118 falls into the conveying track 121 at a time. In this embodiment, the bottom of the blanking trough 118 is a part of the conveying track 121. When in use, the bar feeding device also includes a support frame 14. The hopper 11 and the bar conveying mechanism 12 are both arranged on the support frame 14. At this time, the upper surface of the support frame 14 serves as the bottom plate of the blanking trough 118. The upper surfaces of the high upright plate 111, the low upright plate 113 and the support frame 14 enclose the conveying track 121.

[0046] The lower end of the inclined plate 112 is fixedly connected to the upper end of the short upright plate 113, so that the multiple bars 10 in the bucket cavity can be guided to fall into the drop chute 118 by gravity, without the need for other driving mechanisms, thus simplifying the structure of the bar feeding device;

[0047] The high vertical plate 111, the inclined plate 112 and the low vertical plate 113 are arranged between the two side plates 114. The two side plates 114 can prevent multiple bars 10 from sliding out on the left and right sides of the hopper 11 on the one hand, and on the other hand, can ensure that multiple bars 10 are aligned, so that the position of the bars 10 falling into the conveying track 121 is determined.

[0048] In one embodiment, the blanking trough 118 can accommodate multiple bars 10 in the longitudinal direction, that is, the height of the blanking trough 118 is higher than the cross-sectional dimensions of at least two bars 10. At this time, the blanking trough 118 can accommodate multiple bars 10 in the upper and lower parts, and the multiple bars 10 are arranged in sequence. When the bar 10 on the conveying track 121 is pushed out of the pushing end 1212 by the output end of the pushing mechanism 122, and the output end of the pushing mechanism 122 is reset to the pushing end 1211 position, the upper bar 10 directly falls into the conveying track 121, and the next bar 10 can be directly conveyed, thereby improving the conveying efficiency and reliability of the bar 10.

[0049] Reference Figure 3 In one embodiment, the hopper 11 further includes a limiting mechanism 115, which can be used to limit the bars 10 in the hopper 11 from continuing to fall into the chute 118 to stop the loading of the bars 10, and can also be used to prevent the bars 10 in the hopper cavity from being blocked or stuck;

[0050] The short standing plate 113 is provided with a sliding groove 1131, the lower end of the inclined plate 112 is provided with an opening groove 1121, and the limiting mechanism 115 includes a lifting driving member Ⅰ 1151 and a limiting plate 1152 provided on the output end of the lifting driving member Ⅰ 1151;

[0051] The lifting drive member I1151 drives the limit plate 1152 to rise and fall in the sliding groove 1131. When the limit plate 1152 rises, the limit plate 1152 extends out of the lower end of the inclined plate 112 through the opening groove 1121, so that the lower end of the inclined plate 112 has the limit plate 1152. At this time, the bar 10 in the bucket cavity can no longer fall into the drop chute 118 through the inclined plate 112. After all the bar 10 in the drop chute 118 is loaded, the loading operation ends. In this embodiment, the limit mechanism 115 can also restore the blocked or stuck bar 5 to a flowing state by lifting the limit plate 1152 when multiple bar 10 are blocked or stuck in the bucket cavity, thereby ensuring the stability of loading.

[0052] In one embodiment, the hopper 11 further includes a material blocking mechanism 116, which is used to block the material drop chute 118, restricting the bar material 10 from continuing to fall into the material drop chute 118, so as to stop the loading of the bar material 10;

[0053] The material blocking mechanism 116 includes a linear driving member III 1161 and a material blocking plate 1162 disposed on the output end of the linear driving member III 1161;

[0054] The high vertical plate 111 or the low vertical plate 113 is provided with a blocking groove 1111 in the middle or upper part of the material drop trough 118. In a preferred embodiment, the blocking groove 1111 is arranged in the middle part of the high vertical plate 111, and the linear driving member III 1161 drives the blocking plate 1162 to extend into the material drop trough 118 through the blocking groove 1111 to block the material drop trough 118 and prevent the rod material 10 in the bucket cavity from falling into the material drop trough 118 again.

[0055] In one embodiment, the hopper 11 further includes a material shaking mechanism 117, which is used to shake the bar material 10 in the hopper cavity, especially to shake the bar material 10 at the notch of the material drop chute 118, so as to avoid the problem of the bar material 10 in the hopper cavity being blocked or stuck;

[0056] The material shaking mechanism 117 includes a motor 1171 and a material shaking plate 1172. The motor 1171 is arranged at one end of the high standing plate 111 away from the bucket cavity, and the material shaking plate 1172 is arranged on the output shaft of the motor 1171.

[0057] The high vertical plate 111 is longitudinally provided with a slot 1112, and the shaking plate 1172 partially extends into the bucket cavity through the slot 1112, thereby moving the rod 10 near the slot 1112, thereby moving the rod 10 to avoid the problem of the rod 10 being stuck in the bucket cavity.

[0058] In one embodiment, the conveying track 121 also includes an outer conveying track 1213 arranged on the outside of the hopper 11, and the upper end of the outer conveying track 1213 has an opening 1214, and the outer conveying track 1213 and the conveying track 121 at the bottom of the material chute 118 are connected to each other. By setting the outer conveying track 1213, it is convenient for the staff to directly observe the loading situation and judge the loading status.

[0059] In one embodiment, the bar material feeding device further includes a material pressing and pushing mechanism 13, which is used to press the bar material 10 into the outer conveying track 1213 and follow the bar material 10 to move along the outer conveying track 1213 until the bar material 10 moves out of the push-out end 1212 at the end of the outer conveying track 1213;

[0060] The material pressing and pushing mechanism 13 includes a linear drive member II131, a lifting drive member II132 and a material pressing block 133. The material pressing block 133 is arranged at the output end of the lifting drive member II132. The lifting drive member II132 is used to drive the material pressing block 133 to move toward the opening 1214. The lifting drive member II132 is arranged at the output end of the linear drive member II131. The linear drive member II131 is used to drive the material pressing block 133 to move along the outer conveying track 1213. In one embodiment, the material pressing block 133 blocks the opening 1214, thereby preventing the bar 10 from shaking out of the opening 1214. In another embodiment, a part of the material pressing block 133 blocks the opening 1214, and another part extends into the outer conveying track 1213. While preventing the bar 10 from shaking out of the opening 1214, it can also push the bar 10 to move on the outer conveying track 1213, thereby serving as a supplement to the pushing mechanism 122.

[0061] In one embodiment, the pushing end 1212 is connected to a square rod rounding device. In this embodiment, the rod 10 to be loaded is a square rod, and the next workstation of the rod loading device is a square rod rounding device, which is used to grind the square rod into a round rod, that is, when the rod 10 extends into the pushing end 1212, it directly enters the square rod rounding device for rounding. At this time, a part of the rod 10 is located on the outer conveying track 1213, and another part enters the square rod rounding device, and the rod 10 is driven to rotate by the square rod rounding device. In this embodiment, the loading path of the rod 10 is short, which can improve work efficiency, and by setting the outer conveying track 1213, it can be avoided that the rotating rod 10 affects the rod located in the blanking trough 118, and by setting the pressing and pushing mechanism 13, it can be avoided that the rod 10 is shaken out of the opening 1214.

[0062] In one embodiment, the pushing mechanism 122 includes a linear drive member Ⅰ1221 and a push rod 1222. The push rod 1222 is arranged on the output end of the linear drive member Ⅰ1221, that is, the push rod 1222 is used as the output end of the pushing mechanism 122, and the linear drive member Ⅰ1221 drives the push rod 1222 to move along the bottom of the conveying track 121. In a preferred embodiment, the linear drive member Ⅰ1221 adopts a linear module, and two in-position sensors 1223 are arranged on the base of the linear module to control the push rod 1222 to completely push out the bar 10 and completely reset the push rod 1222. In addition, on the slider of the linear module (the output end of the linear module), a limit rod 1224 can also be arranged toward the side plate 114 of the hopper 11 to limit the movement limit position of the slider.

[0063] Among them, the linear drive component I1221, the linear drive component II131, the linear drive component III1161, the lifting drive component I1151 and the lifting drive component II132 can all adopt cylinders, hydraulic cylinders or linear modules. In a preferred embodiment, the linear drive component I1221 and the linear drive component II131 both adopt linear modules and are arranged parallel to the direction of the conveying track 121 to ensure the stroke length of the linear drive.
