Automatic bar unloading device

Abstract

This utility model relates to the field of automatic feeding technology and discloses an automatic bar feeding device, including a machine body with a lifting assembly and a ramp-shaped feeding plate. The lifting assembly includes a lifting plate, a receiving component, and an ejector component. The lifting plate is vertically movable and located at the front end of the ramp-shaped top of the feeding plate. The receiving component is connected to the lifting plate and is used to receive the bar material placed from the outside. The ejector component is rotatably connected to the lifting plate, and the ramp-shaped top of the feeding plate is adapted to abut against the ejector component. When the bar material is placed on the receiving component, the lifting plate moves down, causing the feeding plate to abut against the ejector component, which then swings upward to eject the bar material from the receiving component, allowing the bar material to roll down the feeding plate. By reducing the descent height of the bar material through the lifting plate, damage caused by the bar material rolling from an excessive height is prevented. The ejector component descends with the lifting plate and rotates upward during the descent, ejecting the bar material from the receiving component. The structure is simple and ingenious, and the cost is low.

Description

Technical Field

[0001] This utility model relates to the field of automatic feeding technology, and more specifically, to an automatic feeding device for bar stock. Background Technology

[0002] In the bar stock grinding process, the bars need to be transported. With the continuous development and progress of mechanical manufacturing technology, automatic bar stock unloading devices have gradually emerged, replacing manual unloading, saving manpower, and improving efficiency. However, existing automatic bar stock unloading devices have some shortcomings. The bar stock falls from a relatively large height, and it is prone to damage when falling from a height. Utility Model Content

[0003] To address at least one of the aforementioned problems, this utility model first provides an automatic bar stock feeding device, comprising a machine body, on which a lifting assembly and a ramp-shaped feeding plate are provided. The lifting assembly includes a lifting plate, a receiving member, and an ejector. The lifting plate is vertically movable and positioned at the front end of the ramp-shaped top of the feeding plate. The receiving member is connected to the lifting plate and is used to receive bar stock placed externally. The ejector is rotatably connected to the lifting plate, and the ramp-shaped top of the feeding plate is adapted to abut against the ejector. When bar stock is placed onto the receiving member, the lifting plate moves downward, causing the feeding plate to abut against the ejector, which in turn causes the ejector to swing upward, ejecting the bar stock from the receiving member and causing the bar stock to roll down the feeding plate.

[0004] Optionally, the receiving member is provided with a first guide slope and a limiting part. The limiting part is located at the guide end of the first guide slope, and a hook is formed between the first guide slope and the limiting part. The external bar rolls along the first guide slope into the hook, and the hook is used to restrict the bar from rolling out.

[0005] Optionally, when the bar stock is located in the hook portion, the center of the bar stock is higher than the top surface of the limiting portion in the vertical direction, or the center of the bar stock is flush with the top surface of the limiting portion in the vertical direction.

[0006] Optionally, the upper end of the ejector is provided with a second guide slope. When the ejector is far away from the unloading plate and at the lower limit position, the angle between the first guide slope and the horizontal plane is less than or equal to the angle between the second guide slope and the horizontal plane, and the bar can roll along the second guide slope to the unloading plate.

[0007] Optionally, the upper end of the lifting plate is provided with a sliding groove, the receiving member is provided with a connecting seat, the ejector and the connecting seat are rotatably connected, the bottom of the connecting seat is provided with a slider, and the slider and the sliding groove are slidably connected.

[0008] Optionally, there are at least two ejector members and at least two receiving members.

[0009] Optionally, one end of the ejector is provided with a limiting wall, which is adapted to abut against the lifting plate to limit the downward movement of the ejector.

[0010] Optionally, the feeding plate includes a first feeding plate and a second feeding plate, with a receiving cavity for placing bar stock formed between the first feeding plate and the second feeding plate. The machine body is provided with an adjusting screw, which is threadedly connected to the first feeding plate and passes through the second feeding plate. When the adjusting screw is rotated, the first feeding plate moves along the adjusting screw to adjust the distance between the first feeding plate and the second feeding plate, thereby adapting to bar stock of different lengths.

[0011] Optionally, the machine body is provided with a first slide rail and a second slide rail, the front bottom of the first feeding plate and the second feeding plate are slidably connected to the first slide rail, and the rear bottom of the first feeding plate and the second feeding plate are slidably connected to the second slide rail.

[0012] Optionally, one end of the adjusting screw is connected to a driving component, which is located on the outer side of the machine body. When the driving component is rotated, the adjusting screw rotates synchronously.

[0013] Compared to existing technologies, the automatic bar feeding device of this invention, during automated production, typically places external bar stock onto a receiving component after being gripped by an external mechanical claw. The receiving component is mounted on the upper end of a lifting plate. The lifting plate includes an upward position and a downward position. When the lifting plate is in the upward position, the receiving component easily receives the bar stock from the mechanical claw while preventing the mechanical claw from touching other internal parts of the machine, ensuring stable placement of the bar stock. After the lifting plate descends, the receiving component and the ejector component descend together with the lifting plate. After the lower end of the ejector component abuts against the feeding plate, due to the continuous descent of the lifting plate, one end of the ejector component is confined to the upper part of the feeding plate, while the other end continues to descend with the lifting plate, thus exhibiting an upward swing posture. During the upward swing of the ejector component, it pushes the bar stock on the receiving component upward, causing the bar stock to detach from the receiving component and roll along the ejector component onto the feeding plate, and then roll down the feeding plate. When the lifting plate rises again, the ejector moves away from the feeding plate. Under its own weight and / or the pressure of the external bar stock, the ejector can swing downwards, thus allowing the bar stock to be smoothly inserted.

[0014] The lifting plate lowers the bar stock's descent height, preventing it from rolling off and causing damage. The ejector moves down with the lifting plate and rotates upward during the descent, pushing the bar stock out of the receiving component. The ejector's rotation does not require an additional drive device; it is achieved solely through the contact of the discharge plate and the lifting of the lifting plate. The structure is simple, ingenious, and low-cost, effectively receiving, lowering, and ejecting the bar stock. Attached Figure Description

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] The accompanying drawings of the embodiments of this utility model provide a coordinate system XYZ, where the positive direction of the X-axis represents the left and the negative direction of the X-axis represents the right, the positive direction of the Y-axis represents the front and the negative direction of the Y-axis represents the back, the positive direction of the Z-axis represents the top and the negative direction of the Z-axis represents the bottom.

[0024] This utility model embodiment provides an automatic bar stock feeding device, combined with Figures 1 to 5As shown, the machine includes a body 1, which is equipped with a lifting assembly and a ramp-shaped feeding plate. The lifting assembly includes a lifting plate 2, a receiving member 3, and an ejector 4. The lifting plate 2 is vertically movable and located at the front end of the ramp-shaped top of the feeding plate. The receiving member 3 is connected to the lifting plate 2 and is used to receive the bar stock 7 placed from the outside. The ejector 4 is rotatably connected to the lifting plate 2. The ramp-shaped top of the feeding plate is adapted to abut against the ejector 4. When the bar stock 7 is placed on the receiving member 3 from the outside, the lifting plate 2 moves down so that the feeding plate abuts against the ejector 4, causing the ejector 4 to swing upward and push the bar stock 7 on the receiving member 3 out, so that the bar stock 7 rolls down along the feeding plate.

[0025] like Figure 3 As shown, in this embodiment, the machine body 1 is provided with a cylinder 15, which drives the lifting plate 2 to move up and down. The lifting plate 2 is located between the feeding plate and the inner wall of the front end of the machine body 1, and transports the bar stock 7 from top to bottom to the feeding plate, so that the bar stock 7 rolls down the inclined feeding plate under its own gravity.

[0026] In the automated production process, the external bar stock 7 is generally gripped by an external mechanical claw (not shown) and placed on the receiving component 3, which is installed on the upper end of the lifting plate 2. The lifting plate 2 has an upward position and a downward position. When the lifting plate 2 is in the upward position, the receiving component 3 can easily receive the bar stock 7 on the mechanical claw, while preventing the mechanical claw from touching other parts inside the machine body 1. The bar stock 7 is placed stably. After the lifting plate 2 descends, the receiving component 3 and the ejector 4 descend together with the lifting plate 2. After the lower end of the ejector 4 abuts against the unloading plate, because the lifting plate 2 continues to descend, one end of the ejector 4 is limited to the upper part of the unloading plate, while the other end continues to descend with the lifting plate 2, thus presenting an upward swing posture. During the upward swing of the ejector 4, the bar stock 7 on the receiving component 3 is pushed upward, so that the bar stock 7 is separated from the receiving component 3 and rolls down the ejector 4 onto the unloading plate, and then rolls down the unloading plate. When the lifting plate 2 rises again, the ejector 4 moves away from the feeding plate. The ejector 4 can swing downward under its own weight and / or the pressure of the external bar 7, so that the bar 7 can be smoothly inserted.

[0027] The lifting plate 2 lowers the descent height of the bar stock 7 to prevent it from rolling down from an excessive height and causing damage. The ejector 4 descends with the lifting plate 2 and rotates upward during the descent to eject the bar stock 7 out of the receiving member 3. The rotation of the ejector 4 does not require an additional drive device; it can be achieved solely by the contact of the unloading plate and the lifting of the lifting plate 2. The structure is simple, ingenious, and low-cost, achieving the effects of receiving the bar stock 7, lowering the descent height, and ejecting the bar stock 7.

[0028] like Figure 4As shown, optionally, the receiving member 3 is provided with a first guide slope 31 and a limiting part 32. The limiting part 32 is provided at the guide end of the first guide slope 31. A hook part 33 is formed between the first guide slope 31 and the limiting part 32. The outer bar 7 rolls along the first guide slope 31 into the hook part 33. The hook part 33 is used to restrict the bar 7 from rolling out.

[0029] In this embodiment, the receiving member 3 is fixedly connected to the top of the lifting plate 2, and the bottom of the receiving member 3 is parallel to the horizontal plane. When the external mechanical claw places the bar 7 on the receiving member 3, it should be aligned with the hook part 33. The first guide slope 31 can increase the fault tolerance of placing the bar 7. Even if the bar 7 is placed on the first guide slope 31, it can roll along the first guide slope 31 into the hook part 33. The limiting part 32 prevents the bar 7 from continuing to roll away from the receiving member 3.

[0030] like Figure 4 As shown, optionally, when the bar stock 7 is located in the hook portion 33, the center of the bar stock 7 is higher than the top surface of the limiting portion 32 in the vertical direction, or the center of the bar stock 7 is flush with the top surface of the limiting portion 32 in the vertical direction. This arrangement allows the limiting portion 32 to function as a limiting element while reducing obstruction during the ejection of the bar stock 7, and also allows for the adaptation of bar stocks 7 with different diameters. After the ejector 4 lifts the bar stock 7, when the distance the bar stock 7 rises exceeds the height of the limiting portion 32, it can be ejected from the hook portion 33 and roll out of the receiving member 3 along the ejector 4.

[0031] like Figure 4 and 5 As shown, optionally, the upper end of the ejector 4 is provided with a second guide slope 41. When the ejector 4 is far away from the unloading plate and is at the lower limit position, the angle between the first guide slope 31 and the horizontal plane is less than or equal to the angle between the second guide slope 41 and the horizontal plane, and the bar 7 can roll along the second guide slope 41 to the unloading plate.

[0032] In this embodiment, when the ejector 4 is at its lower limit position, the portion of the second guide ramp 41 near the bar stock 7 is lower than or equal to the height of the first guide ramp 31, thus not affecting the insertion of the bar stock 7. When the ejector 4 swings upward until the portion of the second guide ramp 41 near the bar stock 7 is higher than the height of the first guide ramp 31, the bar stock 7 is lifted by the second guide ramp 41 to the point where it is no longer limited by the limiting part 32, and then rolls along the second guide ramp 41 onto the unloading plate. The ejector 4, while providing the ejection effect, also acts as a transition, allowing the bar stock 7 to roll smoothly onto the unloading plate.

[0033] like Figure 2 and 4As shown, optionally, the upper end of the lifting plate 2 is provided with a sliding groove 21, the receiving member 3 is provided with a connecting seat 34, the ejector 4 and the connecting seat 34 are rotatably connected, the bottom of the connecting seat 34 is provided with a slider 35, and the slider 35 and the sliding groove 21 are slidably connected.

[0034] In this embodiment, the receiving part 3 and the ejector part 4 are connected together by the connecting seat 34, and the position on the lifting plate 2 is adjusted by the cooperation of the slider 35 and the slide groove 21. This can accommodate bars of different lengths 7, so that the receiving part 3 and the ejector part 4 can act on the middle position of bars of different lengths 7, making the bar 7 more stable under force.

[0035] Optionally, there are at least two ejector pieces 4 and at least two receiving pieces 3.

[0036] like Figure 1 As shown, in this embodiment, there are two ejector pieces 4 and two receiving pieces 3. This arrangement allows the left and right ends of the bar stock 7 to be stressed simultaneously, further increasing stability and preventing the bar stock 7 from tilting to one side. It also reduces the width of the ejector pieces 4 and the receiving pieces 3, reducing material usage and saving costs. Furthermore, by adjusting the position of the slider 35 and the groove 21, it can accommodate bar stock 7 of different lengths.

[0037] like Figure 5 As shown, optionally, one end of the ejector 4 is provided with a limiting wall 42, which is adapted to abut against the lifting plate 2. When the ejector 4 is at the lower limit position, the limiting wall 42 and the rear side wall of the lifting plate 2 are in contact to limit the downward movement of the ejector 4.

[0038] Optionally, the feeding plate includes a first feeding plate 5 and a second feeding plate 6, with a receiving cavity for placing the bar stock 7 formed between the first feeding plate 5 and the second feeding plate 6. The machine body 1 is provided with an adjusting screw 11, which is threadedly connected to the first feeding plate 5 and passes through the second feeding plate 6. When the adjusting screw 11 is rotated, the first feeding plate 5 moves along the adjusting screw 11 to adjust the distance between the first feeding plate 5 and the second feeding plate 6, thereby adapting to bar stock 7 of different lengths.

[0039] like Figure 1 As shown, in this embodiment, the bottom of the feeding plate is parallel to the horizontal plane, and the upper end is inclined to form a slope. The first feeding plate 5 is close to the left side wall of the hopper, and the second feeding plate 6 is close to the right side wall of the hopper. The first feeding plate 5 and the second feeding plate 6 are a group, and two or more groups can be arranged at intervals to further adapt to bars 7 of different lengths.

[0040] Optionally, the machine body 1 is provided with a first slide rail 13 and a second slide rail 14. The front bottom of the first feeding plate 5 and the second feeding plate 6 are slidably connected to the first slide rail 13, and the rear bottom of the first feeding plate 5 and the second feeding plate 6 are slidably connected to the second slide rail 14.

[0041] like Figure 1 and 3 As shown, in this embodiment, the first slide rail 13 and the second slide rail 14 make the sliding structure of the first feed plate 5 and the second feed plate 6 more stable, and at the same time, the first slide rail 13 and the second slide rail 14 also play a supporting role.

[0042] Optionally, one end of the adjusting screw 11 is connected to a driving member 12, which is located on the outer side of the body 1. When the driving member 12 is rotated, the adjusting screw 11 rotates synchronously.

[0043] like Figure 1 As shown, the driving component 12 can be a motor or can be rotated manually. Rotating the driving component 12 causes the drive shaft to drive the adjusting screw 11 to rotate. In this embodiment, the driving component 12 is a turntable, and rotating the turntable drives the adjusting screw 11 to rotate.
