Description

Technical Field

[0001] The invention relates to the technical field of bar feeding, in particular to an automatic feeding bar feeder. Background Art

[0002] Bar feeders play an important role in industrial production, especially in the field of bar processing. They can quickly and accurately transport bars to processing equipment, reducing the time and labor intensity of manual handling and loading. When loading some shorter bars, the bars will be randomly piled up in a stacking hopper. When the push plate on the feeder moves upward, it will push some of the bars upward and transport the bars to the next station. However, when the push plate pushes the bars upward, because the bars are stacked too messily, some of the bars pushed upward by the push plate will also be randomly placed on the top of the push plate. When the push plate moves upward to a certain height, the bars that are not parallel to the top of the push plate will fall down. Therefore, the number of bars loaded by the feeder each time cannot be determined, and the spacing of the bars on the top of the push plate cannot be effectively controlled, which makes the bars transported to the subsequent process too dense or too sparse, resulting in unstable feeding of subsequent processing procedures. Sometimes too much feeding may cause overload or blockage of the processing equipment, and sometimes too little feeding will put the processing equipment in an idle waiting state, reducing the overall production efficiency.

DETAILED DESCRIPTION

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. Example 1

[0029] Reference Figure 1-Figure 6, which is the first embodiment of the present invention, and provides an automatic feeding bar feeder, the automatic feeding bar feeder includes a pushing assembly 200, including a pushing plate 201, an extension plate 201a, a spacer block 201b, a pushing rod 201c, a rotating wheel 201d, a movable column 201e, a supporting rod 201f, a connecting rod 201g and a fixed shaft 201h, the extension plate 201a is hinged to one side of the pushing plate 201 through a hinge plate, the spacer block 201b is fixed to the top of the pushing plate 201, a sliding groove 201-1 is provided on the pushing plate 201, the pushing rod 201c is located in the sliding groove 201-1, a chamber 201-2 is provided in the pushing plate 201, and the rotating wheel 201d is hinged to the pushing plate 201 through a hinge plate. The plate is rotatably connected to the inner wall of the chamber 201-2, the movable column 201e is inserted into the rotating wheel 201d, the support rod 201f is fixed to the bottom of the push rod 201c, the two ends of the connecting rod 201g are respectively fixed to the support rod 201f and the movable column 201e, the fixed shaft 201h is fixed in the rotating wheel 201d, and a spiral groove 201e-1 is provided on the movable column 201e. The fixed shaft 201h slides in the spiral groove 201e-1. The push rod 201c is elastic and will bend when encountering resistance. There are multiple spacer blocks 201b, which are evenly distributed in a straight line on the top of the push plate 201. The top of the spacer block 201b is arc-shaped, and the number of push rods 201c corresponds to the spacer blocks 201b.

[0030] The push plate 201 is inclined, and one side of the bottom of the extension plate 201a is inclined. The extension plate 201a increases the width of the top of the push plate 201, so that when the push plate 201 pushes the rod to move upward, the rod that is not parallel to the push plate 201 will not fall downward.

[0031] When the push plate 201 moves upward, the rotating wheel 201d rotates and drives the fixed shaft 201h to slide in the spiral groove 201e-1. The cooperation between the two drives the movable column 201e to move, and the movable column 201e drives the connecting rod 201g and the support rod 201f to move, so that the support rod 201f drives the push rod 201c to move. When the push rod 201c moves, it will apply a thrust to the rod on the top of the push plate 201. If the rod is not parallel to the push plate 201, it can push the rod to rotate so that the rod is parallel to the top of the push plate 201. If the rod is parallel to the top of the push plate 201, When the push rod 201c contacts the cross section of the rod and encounters resistance, the push rod 201c will bend so as not to hinder the normal movement of other push rods 201c. In this way, the rod on the top of the push plate 201 can be parallel to the push plate 201, so that after the push plate 201 moves upward to a certain height, the rod will not fall downward. At the same time, the multiple rods are spaced by the spacer blocks 201b so that the distances between the multiple rods are uniform, thereby ensuring that subsequent processing steps can be carried out continuously and evenly, reducing the time wasted due to waiting for rods or processing too many rods, and greatly improving production efficiency. Example 2

[0032] Reference Figure 1-Figure 8 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0033] Specifically, a support block 202a is fixed to the inner wall of the chamber 201-2, a movable rod 202b is inserted into the support block 202a, and an impact block 202c is fixed to the top of the movable rod 202b.

[0034] As the push plate 201 moves upward, the movable rod 202b will drive the impact block 202c to move upward, and the impact block 202c will impact the top wall of the chamber 201-2, so that the push plate 201 can vibrate, and then the rod on the top of the push plate 201 can be quickly rotated to a state parallel to the top of the push plate 201, and evenly placed between multiple spacer blocks 201b.

[0035] Specifically, a force-bearing plate 202d is fixed to the bottom end of the movable rod 202b, a rotating sleeve 202e is fixed to one side of the rotating wheel 201d, and a pushing block 202f is fixed to one side of the rotating sleeve 202e.

[0036] When the rotating wheel 201d rotates, it drives the push block 202f to rotate. When the push block 202f rotates to the upper side, it drives the force-bearing plate 202d to move upward, so that the force-bearing plate 202d drives the movable rod 202b to move upward.

[0037] Specifically, a first spring 202g is sleeved on the outer side of the movable rod 202b, and two ends of the first spring 202g are respectively fixed to the supporting block 202a and the impact block 202c.

[0038] When the push block 202f is separated from the force-bearing plate 202d, the impact block 202c is pulled downward by the first spring 202g, so that the impact block 202c can be reset and can impact the inner top wall of the chamber 201-2 again.

[0039] Specifically, a support frame 203a is fixed to the inner wall of the chamber 201-2, and a support plate 203b is movably connected inside the support frame 203a. One side of the support plate 203b is in contact with the extension plate 201a. A movable groove 203b-1 is provided on the support plate 203b, and a limiting column 203c is arranged in the movable groove 203b-1. A limiting hole 203d is provided on the support frame 203a, and the limiting column 203c is engaged with the limiting hole 203d. A second spring 203e is fixed to the bottom of the limiting hole 203d.

[0040] When the limiting column 203c is engaged with the limiting hole 203d, the support plate 203b can be locked through the cooperation of the two, and the extension plate 201a can be supported by the support plate 203b, so as to prevent the extension plate 201a from tilting downward and causing the rod on the top to fall downward.

[0041] The second spring 203e is used to apply an upward thrust to the limiting column 203c, so that the limiting column 203c and the limiting hole 203d are more tightly engaged.

[0042] Specifically, a third spring 203f is fixed to one side of the support plate 203b, and one end of the third spring 203f is fixed to the inner wall of the support frame 203a.

[0043] The third spring 203f applies a pushing force to the support plate 203b so that it can return to its original position. Example 3

[0044] Reference Figure 1-Figure 8 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0045] Specifically, a connecting block 204a is fixed to the bottom of the support rod 201f, an extrusion plate 204b is fixed to the bottom of the connecting block 204a, a force-bearing rod 204c that matches the extrusion plate 204b is fixed to the top of the support plate 203b, an extrusion block 204d corresponding to the limiting column 203c is fixed to one side of the extrusion plate 204b, one side of the extrusion plate 204b is inclined, and one side of the bottom of the extrusion block 204d is inclined.

[0046] A through slot is provided on the support frame 203a, and the force-bearing rod 204c is movably connected with the through slot. When the support rod 201f moves a certain distance, it will drive the bottom inclined surface of the extrusion block 204d to contact the limiting column 203c, and push the limiting column 203c to move downward, so that the limiting column 203c is separated from the limiting hole 203d. At the same time, the inclined surface of the extrusion plate 204b will contact the force-bearing rod 204c, and push the force-bearing rod 204c to move, and drive the support rod 201f to move through the force-bearing rod 204c, so that the support rod 201f is separated from the extension plate 201a, thereby releasing the support for the extension plate 201a. At this time, the extension plate 201a will tilt downward due to its own weight, and then the excess rods on its top will fall down, thereby avoiding excessive loading of rods.

[0047] Specifically, a friction block 201d - 1 is fixed on the rotating wheel 201d , and one side of the rotating wheel 201d extends to the outside of the push plate 201 and is movably connected to the push plate 201 .

[0048] The rotating wheel 201d is located on one side outside the push plate 201 and contacts the material baffle plate 102. The friction block 201d-1 increases the friction between the rotating wheel 201d and the material baffle plate 102. When the push plate 201 moves upward, the rotating wheel 201d moves upward on one side of the material baffle plate 102 and rotates through the setting of the friction block 201d-1.

[0049] Specifically, it also includes a main body component 100, and a push plate 201 includes a stacking hopper 101, a baffle plate 102 and a blanking plate 103. The stacking hopper 101 is located on one side of the push plate 201, the baffle plate 102 is fixed on one side of the stacking hopper 101, and the blanking plate 103 is fixed on one side of the baffle plate 102.

[0050] The stacking hopper 101 is inclined, and the blanking plate 103 is inclined, which is used to stack shorter bars. The blocking plate 102 is used to block the bars to prevent them from falling downward. The bars lifted by the push plate 201 will roll to the top of the blanking plate 103 and be transported to the next process through the blanking plate 103.

[0051] Specifically, it also includes a driving component 300, which is arranged at the bottom of the stacking hopper 101, including a cylinder 301 and a mounting bracket 302, the output end of the cylinder 301 is fixed to the push plate 201, the mounting bracket 302 is fixed to the bottom of the stacking hopper 101, and the cylinder 301 is fixed to the stacking hopper 101 through the mounting bracket 302.

[0052] The cylinder 301 is used to drive the push plate 201 to move up and down.

[0053] When in use, when the push plate 201 moves upward, the rotating wheel 201d will rotate due to the friction of the baffle plate 102, and drive the fixed shaft 201h to slide in the spiral groove 201e-1, and the movable column 201e is driven to move, and the connecting rod 201g and the support rod 201f are driven to move through the movable column 201e, so that the support rod 201f drives the push rod 201c to move. When the push rod 201c moves, it will apply a thrust to the rod on the top of the push plate 201. If the rod is not parallel to the push plate 201, it can push the rod to rotate so that the rod is parallel to the top of the push plate 201. 01, when the tops of the push rods 201c are parallel, when the push rod 201c contacts the cross section of the rod and encounters resistance, the push rod 201c will bend, so as not to hinder the normal movement of other push rods 201c, so that the rod on the top of the push plate 201 can be parallel to the push plate 201, and then after the push plate 201 moves upward to a certain height, the rod will not fall down, and at the same time, the multiple rods are spaced by the spacer blocks 201b, so that the distances between the multiple rods are uniform, thereby ensuring that the subsequent processing steps can be carried out continuously and evenly, reducing the time waste caused by waiting for rods or processing too many rods, and greatly improving production efficiency.

[0054] When the rotating wheel 201d rotates, it will drive the push block 202f to rotate. When the push block 202f rotates to the upper side, it will push the force plate 202d to move upward, so that the force plate 202d can drive the movable rod 202b to move upward. The movable rod 202b will drive the impact block 202c to move upward, and the impact block 202c will hit the top wall of the chamber 201-2, so that the push plate 201 can vibrate, and then the rod on the top of the push plate 201 can be quickly rotated to a state parallel to the top of the push plate 201, and evenly placed between multiple spacer blocks 201b.

[0055] When the support rod 201f moves a certain distance, it will drive the bottom inclined surface of the extrusion block 204d to contact the limiting column 203c, and push the limiting column 203c to move downward, so that the limiting column 203c is separated from the limiting hole 203d. At the same time, the inclined surface of the extrusion plate 204b will contact the force-bearing rod 204c, and push the force-bearing rod 204c to move, and drive the support rod 201f to move through the force-bearing rod 204c, so that the support rod 201f is separated from the extension plate 201a, thereby releasing the support for the extension plate 201a. At this time, the extension plate 201a will tilt downward due to its own weight, and then the excess rods on its top will fall down, thereby avoiding excessive loading of rods.

[0056] It should be noted that 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 preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
