Description

Technical Field

[0001] The present invention relates to the technical field of steel reinforcement cage processing equipment, and particularly to a steel bar feeding tray. Background Art

[0002] During the welding production process of a steel reinforcement mesh (cage), steel bars (also known as coil materials) need to be stored on a pay-off reel. The traditional pay-off reel includes a base, a rotating shaft arranged on the base, and a cylindrical reel frame surrounded by fixing plates. The reel frame rotates driven by the coil material, so as to realize the feeding and storage of the steel bars on the reel frame.

[0003] In order to improve the processing efficiency, during the subsequent processing of the steel reinforcement cage, generally a set of steel bar cutting device is used to cut two steel bars simultaneously. Therefore, two feeding trays are required for feeding. However, the original steel bar feeding tray can only feed one steel bar, which cannot meet the need of cutting two steel bars simultaneously. Setting two or more feeding trays will greatly increase the floor area. On the other hand, the pay-off reel usually does not have a braking device, which results in a long time for the pay-off reel to rotate and stop during the feeding process, easily causing the steel bars to unwind or be over-released, and even several coils of steel bars slipping out from the top of the pay-off reel at the same time, affecting the normal operation of production and reducing the production efficiency.

[0004] Therefore, the existing steel bar feeding trays still need to be further improved. Summary of the Invention

[0005] The first technical problem to be solved by the present invention is to provide a steel bar feeding tray that can feed two steel bars simultaneously and save floor area according to the current situation of the prior art.

[0006] The second technical problem to be solved by the present invention is to provide a steel bar feeding tray that can be braked in time during rotation according to the current situation of the prior art.

[0007] The technical solution adopted by the present invention to solve the first technical problem is as follows: A steel bar feeding tray, comprising:

[0008] A fixed seat;

[0009] A tray, arranged on the fixed seat and for steel bars to be wound thereon;

[0010] The fixed seat includes a first placement rack located at the lower layer and a second placement rack located at the upper layer. There are two trays, namely a first tray and a second tray. The first tray is arranged on the first placement rack, the second tray is arranged on the second placement rack. The first placement rack has a slide rail for the first tray to slide from outside the first placement rack onto the first placement rack, and a limit component is arranged on the slide rail for limiting the first tray on the slide rail after it moves into place.

[0011] To facilitate the transfer of the first tray, the bottom of the first tray is provided with rollers, which are adapted to the slide rail and are slidably constrained on the slide rail.

[0012] For the sake of ensuring the smoothness of the transfer process of the first tray and the firmness of the fixation after the first tray is matched with the first placement rack, there are two parallel slide rails, and there are two groups of corresponding rollers. Each group of rollers has at least two rollers, and all of them are correspondingly slidably arranged on the same slide rail.

[0013] To limit the first tray on the first placement rack, the limiting component includes multiple groups of limiting blocks. Each group of limiting blocks has two blocks. One of the limiting blocks is arranged on the slide rail and is used to abut against the front side of the foremost roller in a group of rollers, and the other limiting block is detachably connected to the slide rail and is used to abut against the rear side of the rearmost roller in this group of rollers.

[0014] To facilitate the picking and placing of the second tray, the second tray is placed on the second placement rack and can be taken off from the second placement rack.

[0015] The technical solution adopted to solve the second technical problem of the present invention is as follows: both the first tray and the second tray include a chassis, a rotating frame and a braking device. The rotating frame is rotatably arranged on the chassis and can release the steel bars wound thereon during the rotation process. The braking device is arranged on the chassis and acts on the rotating frame to lock the rotating frame.

[0016] For the sake of simplifying the braking device and ensuring the reliability of the braking device, the braking device includes:

[0017] A support frame, arranged on the chassis, includes two oppositely arranged vertical plates, and vertical sliding grooves are formed on the opposite side walls of the two vertical plates;

[0018] A clamping arm assembly, including a first clamping arm, a second clamping arm, a first support arm and a second support arm. The first end of the first clamping arm is hinged to the first end of the first support arm, and the first end of the second clamping arm is hinged to the first end of the second support arm. The second ends of the first support arm and the second support arm are hinged through a first pin shaft, and both ends of the first pin shaft are slidably constrained in the sliding grooves of the two vertical plates. The middle parts of the first clamping arm and the second clamping arm are hinged through a second pin shaft, and the second pin shaft is fixed relative to the support frame;

[0019] A first driving device, arranged on the chassis, and has a power output end that can perform linear reciprocating sliding. The power output end of the first driving device is connected to the clamping arm assembly to drive the first clamping arm and the second clamping arm to rotate relative to each other to clamp or release the rotating frame.

[0020] To be adapted to the structures of the first clamping arm and the second clamping arm of the above-mentioned braking device, an annular plate centered on its own rotation axis and extending downward is provided on the rotating frame. The second ends of the first clamping arm and the second clamping arm are respectively located on the inner and outer sides of the annular plate, and brake pads adapted to the annular plate are connected to both of them.

[0021] For the purpose of simplifying the structure of the first driving device and saving costs, the first driving device is an electric push rod. The output shaft of the electric push rod moves in the horizontal direction and is connected to the first clamping arm or the second clamping arm. It can be conceived that in addition to the above-mentioned electric push rod, the first driving device can also adopt various existing technologies such as air cylinders and oil cylinders.

[0022] To ensure that the rotating frame can be braked in a timely and effective manner, there are at least two sets of the braking devices, which are arranged at intervals along the circumference of the chassis.

[0023] Compared with the prior art, the advantages of the present invention are as follows: The discharge tray of the present invention has two upper and lower layers, and can simultaneously discharge two steel bars, meeting the requirement of cutting two steel bars simultaneously in the next process. The structure of the upper discharge tray arranged in the up and down direction also reduces the floor area of the discharge tray itself. On the other hand, when loading materials, the second material tray on the upper layer can be directly placed on the second placement rack on the upper layer by a gantry crane, and the first material tray on the lower layer can be directly moved along the slide rail to the first placement rack on the lower layer through rollers. After the first material tray is in place, the first material tray can be limited on the slide rail by the limiting component to achieve reliable fixation. This structural design greatly facilitates the process of taking and placing the upper and lower material trays, and improves the processing efficiency of the entire production line.

[0034] The present invention will be further described in detail below with reference to the embodiments in the accompanying drawings.

[0035] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Since the embodiments disclosed in the present invention can be arranged in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to the directions opposite to or consistent with the direction of gravity. In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0036] See Figures 1-10 , which shows a steel bar feeding tray, including a fixed seat 10 and a material tray. The material tray is used for winding steel bars. The material tray wound with steel bars can be placed on the fixed seat 10. When feeding, the rotating frame 24 on the material tray can rotate to release the steel bars.

[0037] See Figure 2 and Figure 3 , the fixed seat 10 of this embodiment is generally cube-shaped and is divided into two layers arranged at intervals in the up and down directions, specifically the first placement rack 11 located in the lower layer and the second placement rack 12 located in the upper layer. Correspondingly, there are also two material trays in this embodiment, namely the first material tray 21 and the second material tray 22. Among them, the first material tray 21 is arranged on the first placement rack 11, and the second material tray 22 is arranged on the second placement rack 12.

[0038] The second material tray 22 is placed on the second placement rack 12 and can be removed from the second placement rack 12. Specifically, the completed second material tray 22 can be removed from the second placement rack 12 by a gantry crane, and a new second material tray 22 wound with steel bars can be placed on the second placement rack 12.

[0039] Continue to refer to Figure 2 and Figure 3 , due to the interference problem of the second placement rack on the fixed seat 10, it is not convenient to use a gantry crane to load and unload the first material tray 21. To solve this technical problem, an important inventive point of the present invention is that a slide rail 13 is provided on the first placement rack 11 for the first material tray 21 to slide from outside the first placement rack 11 onto the first placement rack 11. That is, the slide rail 13 is provided on the first placement rack 11, and one end of the slide rail 13 extends outside the fixed seat 10 (the first placement rack 11) so that the first material rack can be placed on the slide rail 13. Specifically, the bottom of the first material tray 21 has rollers 210, and the rollers 210 are adapted to the slide rail 13 and are slidably constrained on the slide rail 13. As a preferred embodiment, the rollers 210 of the first material tray 21 are of a structure with an annular limiting groove in the middle. After the rollers 210 are placed on the slide rail 13, the slide rail 13 can just be caught in the annular limiting groove of the rollers 210, thereby realizing the limit in the width direction of the slide rail 13.

[0040] Combined with Figure 1 , there are two slide rails 13 on the first placement rack of this embodiment, and the two slide rails 13 are arranged in parallel. Correspondingly, there are two groups of rollers 210, and each group of rollers 210 has at least two and are all correspondingly slidably arranged on the same slide rail 13. This structural design of multiple groups of rollers 210 can ensure the stability of the first material tray 21 during the movement on the ground and the transfer to the first placement rack.

[0041] Refer to Figure 3, in order to limit the first tray 21 on the first placement rack 11, the limiting component of this embodiment includes multiple groups of limiting blocks 14, and the number is the same as the number of slide rails 13 on the first placement rack (the same as the number of groups of the first tray 21). Among them, there are two limiting blocks 14 in each group. One limiting block 14 is arranged on the slide rail 13 and is used to abut against the front side of the foremost roller 210 in a group of rollers 210, and the other limiting block 14 is detachably connected to the slide rail 13 and is used to abut against the rear side of the rearmost roller 210 in this group of rollers 210. Specifically, the limiting block 14 can be fixed together with the connecting plate 141, and the connecting plate 141 and the slide rail 13 are fixed by screws, so as to realize the fixation of the limiting block 14. More specifically, the side of the limiting block 14 facing the roller 210 has a positioning notch, which is used to be stuck in the middle position of the roller 210 (corresponding to the annular limiting groove), so as to realize the limiting of the roller 210 (the first tray 21) in the up and down direction.

[0042] See Figures 4-9 , in this embodiment, in addition to the first tray 21 being provided with rollers 210, the structures of the first tray 21 and the second tray 22 are basically the same, and both include a chassis 23, a rotating frame 24 and a braking device 30. The rotating frame 24 can be rotatably arranged on the chassis 23 through a bearing provided at the bottom, and can release the steel bars wound thereon during the rotation process. Among them, the outer periphery of the chassis 23 also has an annular baffle 26 for surrounding the outer periphery of the rotating frame 24. The top edge position of the annular baffle 26 also has a baffle rod 28 that can be turned up and down relative to the annular baffle 26. There are multiple baffle rods 28, which are arranged at intervals along the circumferential direction of the above-mentioned annular baffle 26. The above-mentioned baffle rods 28 can be turned down to be in a horizontal state and are located above the steel bars wound on the rotating frame 24 to prevent the steel bars from coming out from above during the release process. An outlet 27 is also opened on the annular baffle 26 for the steel bars to be released outward during the rotation of the rotating frame 24.

[0043] See Figure 6 and Figure 7 , the rotating frame 24 has an annular plate 25 centered on its own rotation axis and extending downward. The annular plate 25 can cooperate with the first clamping arm 321 and the second clamping arm 322 of the following braking device 30 to realize the braking effect on the rotating frame 24.

[0044] Continue to see Figure 6 and Figure 7 , the braking device 30 of this embodiment includes a support frame 31, a clamping arm assembly 32 and a first driving device 36. The clamping arm assembly 32 is arranged on the support frame 31, and the first driving device 36 is arranged on the chassis 23 of the first tray 21. Its power output end is connected to the clamping arm assembly 32. When operating, it can drive the clamping arm component to open and close.

[0045] The support frame 31 is provided on the chassis 23 and includes two oppositely arranged vertical plates 310. On the opposite side walls of the two vertical plates 310, there are vertically opened sliding grooves 311. Specifically, the support frame 31 in this embodiment is a U-shaped frame, and the two opposite arms of the U-shaped frame correspondingly form the above two vertical plates 310.

[0046] The clamping arm assembly 32 includes a first clamping arm 321, a second clamping arm 322, a first arm 323, and a second arm 324. The first end of the first clamping arm 321 is hinged to the first end of the first arm 323, and the first end of the second clamping arm 322 is hinged to the first end of the second arm 324. The second ends of the first arm 323 and the second arm 324 are hinged by a first pin shaft 33, and both ends of the first pin shaft 33 are slidably constrained in the sliding grooves 311 of the two vertical plates 310. The middle parts of the first clamping arm 321 and the second clamping arm 322 are hinged by a second pin shaft 34, and the second pin shaft 34 is provided on the support frame 31 and is fixed relative to the support frame 31. The second ends of the first clamping arm 321 and the second clamping arm 322 are respectively located on the inner and outer sides of the annular plate 25 of the rotating frame 24, and both are connected with brake pads 35 adapted to the annular plate 25. The brake pads 35 are detachably connected to the second end of the first clamping arm 321 or the second end of the second clamping arm 322, and can be conveniently replaced when severely worn.

[0047] The power output end of the first driving device 36 in this embodiment can perform linear reciprocating sliding, and the power output end of the first driving device 36 is connected to the rotating shaft (not shown) at the hinged position of the first clamping arm 321 and the first arm 323. Preferably, the first driving device 36 in this embodiment can adopt an electric push rod. During the reciprocating movement of the output shaft of the electric push rod in the horizontal direction, the first pin shaft 33 can move up and down in the sliding grooves 311 of the two vertical plates 310. Thus, the first clamping arm 321 and the second clamping arm 322 can be driven to rotate relative to each other, and further, the annular plate 25 of the rotating frame 24 can be clamped or released.

[0048] There are at least two groups of the braking devices 30 in this embodiment, and they are arranged at intervals along the circumference of the chassis 23, thereby ensuring that the rotating frame 24 can be braked in a timely and effective manner.

[0049] The working process of the steel bar feeding tray in this embodiment:

[0050] See Figure 10, when it is necessary to transfer the first tray 21 out of the first placement rack 11, first remove the limit baffle, and then move the first tray 21 along the slide rail 13 to the outside of the first placement rack 11. Similarly, when it is necessary to load the first tray 21, it can be directly moved along the slide rail 13 to the lower first placement rack 11 through the rollers 210 at its own bottom. After the first tray 21 is moved in place, fix the limit baffle on the slide rail 13, so as to limit the first tray 21 on the slide rail 13 and achieve firm fixation. The second tray 22 located on the upper layer can be directly placed on the upper second placement rack 12 or removed from the second placement rack 12 by using a gantry crane.
