DETAILED DESCRIPTION

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the invention is not limited by the specific implementation disclosed below.

[0031] See also Figures 1 to 4 The present invention provides a long bar material conveying line, including a supporting base 100, a material bin 200, a sorting mechanism 300, a material taking mechanism 400 and a material feeding mechanism 500.

[0032] Specifically, the upper surface of the support base 100 is a support surface 110 with a preset inclination angle, and the support surface 110 forms an inclined surface with decreasing height along the material conveying direction. The silo 200 is arranged on the support surface 110, and the silo 200 includes a first baffle 210 and a second baffle 220, and a third baffle 230 arranged vertically, and a material guide channel adapted to the standard length of the bar material is formed between the first baffle 210 and the second baffle 220, and the third baffle 230 is vertical to the ground and fixed to the discharge ends of the first baffle 210 and the second baffle 220.

[0033] The sorting mechanism 300 includes a pusher actuator 310 and a displacement drive assembly 320, which are used to orient the disorderly stacked bars in the silo 200 into an axially consistent stacked array. The pick-up mechanism 400 is used to separate the oriented and arranged bars into individual bars. The feeding mechanism 500 is arranged at the discharge end of the silo 200, and is used to receive the bars taken out by the pick-up mechanism 400 and convey the bars forward.

[0034] When in use, the rods are placed in the silo 200. Since the support surface 110 is inclined, the rods will automatically slide toward the third baffle 230 under the action of gravity. At the same time, under the obstruction of the third baffle 230, some of the inclined rods will automatically adjust their directions. Subsequently, the sorting mechanism 300 is started to orient the disorderly stacked rods in the silo 200 into an axially consistent stacked array. Subsequently, the picking mechanism 400 separates the orientated rods into individual pieces and transports them to the feeding mechanism 500. The feeding mechanism 500 transports the rods forward to the next workstation.

[0035] By adopting the above-mentioned conveyor line, through the cooperation of the material bin 200 and the sorting mechanism 300, the disordered rods are arranged into a directional stacked array, which is convenient for the subsequent single-rod picking of the material by the picking mechanism 400, so that the picking mechanism 400 can smoothly place the rods on the feeding mechanism 500 for conveying to the next workstation, thereby greatly improving the conveying efficiency of the entire conveyor line and completing the conveying work quickly.

[0036] In this embodiment, the sorting mechanism 300 includes a pushing execution component 310 and a displacement driving component 320. The displacement driving component 320 is arranged on the support base 100. The pushing execution component 310 includes a push plate 311 and is located in the silo 200. The push plate 311 is arranged on the displacement driving component 320. The displacement driving component 320 can drive the push plate 311 to move back and forth laterally in a direction close to or away from the third baffle 230.

[0037] As an advantageous implementation, in specific implementation, the reciprocating stroke of the displacement drive assembly 320 can be configured as a progressively increasing stroke. That is, the stroke of the displacement drive assembly 320 is not the largest at the beginning, but is progressively increasing, which can prevent the bar from being pushed over a large range at the beginning, causing the bar to bend and deform.

[0038] Specifically, the displacement driving assembly 320 includes a guide plate 321, a rotation power source 322, a guide rod 323, a slider 324, a first connecting rod 325, a second connecting rod 326 and a connecting block 327; the guide plate 321 and the rotation power source 322 are both fixed on the support base 100, and the guide plate 321 is arranged horizontally, a spiral guide groove is opened on the guide plate 321, and the spiral guide groove is coaxially arranged with the rotation power source 322, and the guide rod 323 is arranged on the power output shaft of the rotation power source 322, and extends along the axial direction of the rotation power source. The slider 324 can be slidably mounted in the spiral groove and can be slidably mounted on the guide rod 323. The support base is provided with a laterally extending linear guide groove. The bottom end of the push plate 311 can be slidably set in the linear guide groove. The push plate 311 is vertically provided with a slide groove on the side facing the guide plate 321. The connecting block 327 can be slidably mounted in the slide groove. The first connecting rod 325 and the second connecting rod 326 are hinged to each other. The end of the first connecting rod 325 is hinged to the slider 324. The second connecting rod 326 is hinged to the push plate 311 through the connecting block 327.

[0039] When the rotary power source 322 is started, the guide rod 323 is driven to rotate. Under the limitation of the spiral guide groove and the linear guide groove, the push plate 311 can be pushed to reciprocate through the slider 324, the first connecting rod 325 and the second connecting rod 326, and the reciprocating motion stroke will increase gradually.

[0040] As a preferred embodiment, inclined guide grooves 211 are disposed on the inner side walls of the first baffle 210 and the second baffle 220 , respectively. The inclined guide grooves 211 are disposed parallel to the support surface 110 , and both ends of the push plate 311 are slidably connected to the inclined guide grooves 211 .

[0041] By tilting the guide groove 211 , the stability of the push plate 311 during movement can be improved.

[0042] In this embodiment, the rotation power source 322 can be a commonly used bidirectional rotating motor in the prior art. It should also be noted that in specific implementation, the displacement drive assembly 320 can also be in other forms, such as: a telescopic cylinder, or a gear rack mechanism.

[0043] As another advantageous implementation, the pushing execution component 310 also includes a material dividing guide component 312, which is arranged on the side wall of the pushing plate 311 facing the bar stock pile, and the side wall of the material dividing guide component 312 facing the bar stock pile gradually protrudes from the middle to the left and right sides.

[0044] When the push plate 311 is pushing the material, since the middle part contacts the bar material first, the bar material is guided from both sides, thereby greatly shortening the sorting time.

[0045] In this embodiment, the material taking mechanism 400 includes a top plate 410, a lifting drive source 420 and a material guide 430. The support base 100 is a hollow member. The support surface 110 is provided with a strip-shaped through groove connected to the inner cavity of the support base 100. The through groove is located in the silo 200 and is arranged close to the inner wall of the third baffle 230. The top plate 410 can be inserted into the through groove so as to slide up and down. The lifting drive source 420 is arranged in the support base 100 and is used for connecting the top plate 410 and driving the top plate 410 to move up and down. The top width of the top plate 410 is greater than the diameter of a single rod but less than the diameter of two rods. The top surface of the top plate 410 is a pushing surface, and the pushing surface is an inclined surface, and the inclination direction of the pushing surface is the same as the inclination direction of the supporting surface 110. The top surface of the third baffle 230 is an inclined surface, and the inclination direction of the top surface of the third baffle 230 is the same as the inclination direction of the supporting surface 110. The material guide member 430 is arranged close to the outer wall of the third baffle 230, and the top surface of the material guide member 430 is an inclined material guide surface, and the inclination direction of the material guide surface is the same as the inclination direction of the supporting surface 110. The feeding mechanism 500 is arranged at the discharge end of the material guide surface, and the rod material rolling down from the material guide surface can roll onto the feeding mechanism 500.

[0046] After finishing, start the lifting drive source 420 to drive the top plate 410 to rise, and the pushing surface pushes the single rod material to rise against the third baffle plate 230. When the pushing surface exceeds the top surface of the third baffle plate 230, the rod material automatically rolls to the top surface of the third baffle plate 230, and then rolls onto the guide member 430 in sequence. Under the guidance of the top surface of the guide member 430, it continues to roll onto the feeding mechanism 500, and the feeding mechanism 500 transports the rod material to the next process.

[0047] As a preferred embodiment, the material picking mechanism 400 also includes a buffer correction plate 440, and a downward-through material leakage groove 450 is arranged at the tail end of the material guide member 430. The buffer correction plate 440 is perpendicular to the material guide surface of the ground, and is arranged adjacent to the material leakage groove 450, and is located on the side away from the support base 100. The length of the material leakage groove 450 is greater than the length of the rod material, and the width of the material leakage groove 450 is greater than the diameter of the rod material but less than the diameter of two rod materials. The rod material leaking from the material leakage groove 450 can directly fall onto the feeding mechanism 500.

[0048] The buffer correction plate 440 can slow down the falling speed and prevent the bar from falling to the feeding mechanism 500 and causing deviation.

[0049] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
