Description

Technical Field

[0001] The utility model belongs to the technical field related to elevators, in particular to a round bar material chain plate elevator. Background Art

[0002] The hoist is an automated bar material automatic lifting and feeding equipment, and is an indispensable part of the automatic production line of shaft and bar parts in the field of mechanical manufacturing. It is mainly used to arrange the parts to be processed neatly according to a specific rule and automatically feed them for truss manipulators or industrial robots to grab. For example, the existing patent No. 201821722835.8 discloses a bar material hoist, including a frame, a baffle, a support plate, a motor, an adjusting rod, a connecting shaft, a lifting bucket, a connecting bar and a top rod. A motor for providing power is installed on the left side of the frame, and two baffles are installed on the top surface of the frame. The baffles are connected by an adjusting rod, and the adjusting rod is fixed to the front end of the top of the frame by an L-shaped steel plate. A lifting bucket for lifting materials is installed in the baffle, and the fixing ring is installed inside the chain. The lifting bucket is connected to the connecting shaft through a chain, and the connecting shaft is located at the top of the frame. The above structure is simple, the design is reasonable, and the cost is low, but the structure has the following problems:

[0003] 1. Since the two sides of the lifting bucket are inserted into the fixed rings inside the chains on both sides through the connecting columns, the lifting bucket can only be removed after removing the chain on one side, which makes it inconvenient to disassemble and change the distance between the two lifting buckets later; making it impossible to load large-sized materials;

[0004] 2. The two front ends of the frame are connected by an adjustment rod, which requires manual operation for adjustment. In addition, since the material is placed between the two baffles, the baffles on both sides need to position and guide the material to facilitate the material to move from top to bottom into the lifting bucket. For such an operation, the distance between the two baffles needs to meet the requirements of not clamping the material but guiding the material to move the logistics order downward. Such an operation is relatively difficult.

[0005] 3. Since the lifting bucket is a structure with edges on the front, back, left and right sides, if the material needs to be accurately dropped into the lifting bucket during the loading process, the installation requirements for each component in the structure are relatively high;

[0006] Therefore, the above structure still has the problems of being unable to quickly adjust the spacing between the feeding components, being unable to feed large-sized materials, being difficult to perform primary material adjustment operations, and having high structural installation requirements.

[0038] Example 1

[0039] See also Figure 1-14As shown, a round bar material chain plate elevator disclosed in this embodiment includes a frame 1, a main transmission shaft 2 and a slave transmission shaft 3, wherein the main transmission shaft 2 passes through the frame 1 and is located at the top of the frame 1, and the slave transmission shaft 3 passes through the frame 1 and is located at the bottom of the frame 1, and for the convenience of rotation, a bearing is provided on both sides of the bottom of the frame 1, and the slave transmission shaft 3 is rotatably connected to the bearings on both sides, and a motor 32 for providing power is installed on the left side of the frame 1, and the output shaft of the motor 32 is connected to the main transmission shaft 2, and two double-sided ear chains 4 distributed on the left and right are provided between the main transmission shaft 2 and the slave transmission shaft 3. , one or more L-shaped lifting chain plates 5 are threadedly connected between two double-sided ear chains 4, a right side plate 6 is arranged on the right side of the frame 1, an inclined conveying plate 1 7 is arranged on the inner side of the right side plate 6, two parallel guide rails 8 are arranged on the frame 1, two sliders 801 are arranged on each guide rail 8, a baffle plate 9 parallel to the right side plate 6 is arranged between the four sliders 801, a conveying plate 2 10 arranged parallel to the conveying plate 1 7 is arranged on the inner side of the baffle plate 9, and the lower ends of the conveying plate 2 10 and the conveying plate 1 7 are used to transfer the material 33 to one of the L-shaped lifting chain plates 5. The slider 801 described in this embodiment can be a slider 801 or a pneumatic slider.

[0040] Preferably, in order to facilitate the disassembly of the L-shaped lifting chain plate 5, two transmission sprockets 11 distributed on the left and right are provided on the main transmission shaft 2, and two transmission sprockets 12 distributed on the left and right are provided on the slave transmission shaft 3. A double-sided ear chain 4 is connected between a transmission sprocket 11 and a transmission sprocket 12. An installation through hole 13 is provided on the ear portion 401 of each double-sided ear chain 4, and a nut 14 is fixed on the back of each installation through hole 13. A installation through hole 15 cooperating with the installation through hole 13 is provided on the L-shaped lifting chain plate 5, and a locking screw 16 is passed through each installation through hole 15. The locking screw 16 passes through the installation through hole 13 and is threadedly connected to the nut 14. In the above structure, since the L-shaped lifting chain plate 5 and the ear portion 401 of the double-sided ear chain 4 are threadedly connected and an external structure is adopted, it is further convenient to quickly disassemble the corresponding L-shaped lifting chain plate 5 at a later time.

[0041] Preferably, in order to improve the protection of the motor, the output of the motor 32 is connected to a worm gear reducer 17 located on the left side of the frame 1, and the output of the worm gear reducer 17 is connected to the main drive shaft 2. A motor protection cover 18 is provided on the side of the frame 1 to cover the outside of the worm gear reducer 17 and the motor 32, and a heat dissipation hole 19 is provided on the outside of the motor protection cover 18. The motor protection cover 18 includes a motor bottom cover 181 and a side cover plate 182. The motor bottom cover 181 is fixed to the side of the frame 1, and the side cover plate 182 is fixed to the motor bottom cover 181 by screws, and the heat dissipation holes 19 are provided on the side cover plate 182. In the above structure, the L-shaped lifting chain plate 5 is given lifting power by adding a worm gear reducer 17 to achieve a large torque, which can drive more products to be lifted at the same time. At the same time, a suitable L-shaped lifting chain plate 5 can be made according to the outer diameter of the product in the later stage to ensure that the L-shaped lifting chain plate 5 will not be stuck, and it is also convenient to quickly replace the L-shaped lifting chain plate 5.

[0042] Preferably, in order to avoid damaging the material 33, a product pad 20 is provided on both the conveying plate 2 10 and the conveying plate 1 7. By adding the product pad 20, it is possible to avoid surface wear and damage of the material 33 during transportation.

[0043] Preferably, in order to facilitate the later material 33 to fall from the L-shaped lifting chain plate 5 and finally facilitate the robot to grab it, two cantilever seats 21 arranged at intervals are arranged on the back of the top of the frame 1 (each cantilever seat 21 is composed of a cantilever support 1 212 and a cantilever support 212), and each cantilever seat 21 is fixed with an inclined unloading cantilever 22, and the high ends of the two unloading cantilever arms 22 are used to convey the material 33 conveyed from one of the L-shaped lifting chain plates 5 above, and a triangular baffle 23 is arranged at the lower end of each unloading cantilever arm 22. The front end of the triangular baffle 23 constitutes a material loading station 24 for the robot to grab the material 33. A lifting cylinder 25 is arranged at the bottom of the lower end of each unloading cantilever 22. A lifting block 26 is connected to the piston rod of the lifting cylinder 25. The surface of the lifting block 26 is provided with a lifting slope 261. The unloading cantilever 22 is provided with an avoidance groove 27 for the lifting block 26 to pass through. After the lifting block 26 is lifted, the lifting slope 261 can be used to lift the single material 33 on the unloading cantilever 22 and transport it to the material loading station 2. 4, the specific working principle of the above structure is as follows: when the L-shaped lifting chain plate 5 with the material 33 is lifted to the rear of the frame 1, the L-shaped lifting chain plate 5 is inverted, and the cross plate 501 of the L-shaped lifting chain plate 5 is inclined to the outside, so under the action of gravity, the material will fall from the L-shaped lifting chain plate 5 and then pour into the space between the two unloading cantilevers 22. Since the unloading cantilever 22 is inclined, the material will move to the lower end under the action of gravity and slowly approach the material loading station 24. Under the action of the triangular baffle 23, all the materials 33 are prevented from moving completely. When the material 33 is in the material loading station 24, the material 33 is discharged in sequence. When the material 33 is located at the lifting block 26, the lifting cylinder 25 is driven to work, driving the lifting block 26 to lift up the material 33. Then, under the action of the lifting slope 261, it is matched with the triangular baffle 23 to allow the single material 33 to fall into the material loading station 24, so that the robot can clamp the single material 33 from the material loading station 24 later. In order to limit the up and down movement of the lifting block 26 in this structure, guide sliders 35 that are clamped on both sides of the lifting block 26 are provided on both sides of the avoidance slot 27.

[0044] Preferably, in order to realize automatic control, a first proximity switch 28 for detecting whether the logistics is in the material loading station 24 is arranged at the front end of each material loading station 24, and a cantilever guard plate 29 is arranged on the outer side of each unloading cantilever 22, and a second proximity switch 30 for detecting the material 33 on the unloading cantilever 22 is arranged on the cantilever guard plate 29. In order to facilitate the placement of the rack, four adjustment feet 31 are arranged at the bottom of the rack 1. In this embodiment, a control cabinet 34 for controlling the operation of the entire equipment is also arranged on the left side of the rack 1. The control cabinet 34 is electrically connected to each electrical device on the device to realize automatic control operation of the equipment. How the control cabinet 34 controls each electrical device and the specific structure of the control cabinet 34 belong to conventional technology in this field, so they are not described in detail. The second proximity switch 30 added above can detect the conveyed material 33 to determine whether there is material passing through the unloading cantilever 22, and the added first proximity switch 28 is used to detect whether the material 33 is conveyed to the material loading station 24, so as to facilitate the subsequent robot to obtain signals.

[0045] The specific working principle of this structure is as follows: according to the length requirement of the material 33, the spacing between the baffle plate 9 and the right side plate 6 is quickly adjusted to facilitate the installation of the material 33 between the conveying plate 2 10 and the conveying plate 1 7. Since the conveying plate 2 10 and the conveying plate 1 7 are structures inclined toward the L-shaped lifting chain plate 5, forming an inclined sliding channel, the material 33 is manually placed on the inclined sliding channel. Therefore, under the action of gravity, the material 33 quickly and automatically slides into the L-shaped lifting chain plate 5. With the drive of the motor 32, the main transmission shaft 2 above is driven to rotate, and the slave transmission shaft 3 below rotates synchronously on the double-sided ear chains 4, so that the double-sided ear chains 4 rotate, thereby realizing the lifting operation of the L-shaped lifting chain plate 5; and the ear parts 401 on the L-shaped lifting chain plate 5 and the double-sided ear chains 4 are threadedly connected, and are an external structure, which is convenient for the later disassembly of each L-shaped lifting chain plate 5; at the same time, following the double-sided ear chains 4 rotates to the other end, rotates to a specific position, and the material 33 will slide down from the L-shaped lifting chain plate 5. At this time, there will be a material receiving slideway (i.e., composed of two material unloading cantilevers 22) at this specific position, and the material 33 will be transported to the material loading station 24 for the truss manipulator or robot to grab. Since the unloading cantilever 22 is set obliquely, there will be multiple materials 33 that will reach the material receiving slideway together. Therefore, there is a triangular baffle 23 at the tail end as a limit, and a lifting cylinder 25 is set below the side of the limit. A lifting block 26 is connected to the piston rod of the lifting cylinder 25. Through the action of the lifting cylinder 25, a single material can be separated from the material 33 behind it, and the single material can be lifted to the material loading station 24 in front. At this time, the truss manipulator or robot will take the material here, so that there is no interference from other materials 33, which is convenient for later loading. Therefore, this structure has the following advantages:

[0046] 1. Since the structure is transmitted through the double-sided ear chain 4, and each L-shaped lifting chain plate 5 is connected to the ear portion 401 on the double-sided ear chain 4 by a separate thread, and is an external structure, it is convenient to disassemble each L-shaped lifting chain plate 5 later, and the distance between the two L-shaped lifting chain plates 5 can be set according to requirements, so that it can load and transmit materials 33 of different diameters; improve the versatility of the equipment; and make later disassembly more flexible and convenient;

[0047] 2. Two inclined conveying plates are used to form an inclined sliding channel, which facilitates the rapid transmission of the material 33 to the L-shaped lifting chain plate. At the same time, one of the two conveying plates is fixedly installed on the frame 1, and the other is driven by a slide rail and a slider to achieve simpler and more convenient operation;

[0048] 3. Moreover, the L-shaped lifting chain plate 5 adopts an external installation structure, which makes the overall installation requirements relatively simple and convenient.

[0049] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions recorded in the aforementioned embodiments and any equivalent replacement of some of the technical features therein, any modification, equivalent replacement, and improvement made are all within the protection scope of the present invention.
