Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of material buffer conveyors, in particular to a material buffer conveyor. Background Art
[0002] During the conveying process of plate-like materials, if the previous assembly line workstation has not completed the operation, the material needs to be kept at the workstation for a certain period of time and wait, so that the assembly line conveying device stops working. However, the stopping of the assembly line conveying device will affect the conveying efficiency of the material. Therefore, a material buffer conveyor is set between the two assembly lines. The material buffer conveyor is a tool for temporarily caching materials, which is mostly used for caching and conveying plate-like materials. The material buffer conveyor in the prior art includes two relatively arranged buffer plates, a conveying mechanism and a frame for conveying plate-like materials. At present, two sets of cylinders are provided in the material buffer conveyor to drive the buffer plates up and down, but the two buffer plates need to move synchronously to ensure that the plate-like materials cached between the two buffer plates will not shake, tilt or fall. However, the two sets of cylinders are difficult to ensure the synchronous movement accuracy of the buffer plates, which leads to the problem that the plate-like materials will still shake, tilt or fall. In addition, in the current material buffer conveyor, when the buffer plates move, the plate-like materials will shake or tilt or collide with the buffer plates, and even cause the materials to be damaged or fall. Utility Model Content
[0003] In response to the shortcomings of the existing technology, the utility model provides a material buffer conveyor to solve the problem that the two buffer plates in the existing technology need to be driven by two cylinders to move up and down, resulting in low synchronization accuracy of the two buffer plates and the material is easily shaken or loosened when the buffer plates move, causing the material to be damaged or dropped.
[0004] To achieve the above-mentioned purpose, the utility model provides a material cache conveyor, including a frame and a cache mechanism arranged on the frame, the cache device including two relatively arranged cache plates, and a conveying mechanism for conveying materials is arranged on both sides of the cache plate, and a plurality of support groups are arranged on the cache plate along the conveying direction of the conveying mechanism, and adjacent support groups are arranged with clearance fit, and each group of support groups is composed of a plurality of support blocks, and the plurality of support blocks are distributed on the cache plate along the height direction of the cache plate and adjacent support blocks are arranged with clearance fit, and a synchronization member is arranged between the two cache plates for driving the other cache plate to slide synchronously when any cache plate slides along the height direction of the frame, and a driving member for driving any cache plate to slide along the height direction of the frame is arranged on the frame, and a fixing member is arranged on the cache plate for fixing the material temporarily stored on the cache plate when the cache plate slides along the height direction of the frame.
[0005] The advantages of adopting the above technical solution are: when the plate-like material passes through the previous assembly line to the rack, the plate-like material is transported by the conveying mechanism until the plate-like material is between the two buffer plates, and the plate-like material is fixed by the buffer plates, that is, a buffer gap is formed between adjacent support blocks, and the buffer gaps on the same horizontal line are combined to form a buffer groove for partial insertion of the plate-like material. When the external assembly line conveying device is not shut down, the conveying mechanism can continue to convey the plate-like material so that the plate-like material moves to the next assembly line, and when the external assembly line conveying device is shut down, the plate-like material is temporarily stored in the buffer. The storage slot is used to realize the caching of plate-like materials. After the plate-like materials are fixed in any cache slot, the driving part drives any cache plate to slide along the height direction of the rack. When the cache plate slides, it is affected by the synchronizing part to make the other cache plate slide synchronously, thereby improving the synchronous sliding accuracy of the two cache plates. The setting of the fixing part is used to fix the materials temporarily stored on the cache plate when the cache plate slides along the height direction of the rack, thereby avoiding the plate-like materials from shaking, loosening, falling or bumping between the two cache plates, thereby avoiding damage or scrapping of the plate-like materials, thereby avoiding waste.
[0006] The utility model is further provided with: a matching block is provided on one side of the two cache plates, and a matching hole is passed through the matching block, and the two matching holes are coaxially aligned. The synchronous part includes a transmission rod arranged between the two matching holes, and two ends of the transmission rod are rotatably connected to the two matching holes. Positioning plates are provided on the frame corresponding to the two cache plate positions, and a positioning seat is slidingly provided on the positioning plate along the height direction of the frame. The two positioning seats are connected to their respective adjacent cache plates. Two positioning wheels are rotatably provided on the positioning plate, and the two positioning wheels are divided into two ends of the positioning plate along the height direction of the positioning plate. Linkage wheels are provided at both ends of the transmission rod, and a linkage belt is driven between the two positioning wheels on the positioning plate and the adjacent linkage wheels. The linkage belt is divided into a vertical part and a horizontal part, and the opening direction of the vertical part is consistent with the height direction of the positioning plate. The positioning seat is connected to the vertical part of the linkage belt, and the driving part includes a servo motor for driving the transmission rod for axial rotation.
[0007] The benefit of adopting the above technical solution is that: when the two cache plates need to slide synchronously, the servo motor starts and drives the transmission rod to rotate axially, the transmission rod rotates and drives the two interlocking wheels to rotate synchronously, and the two interlocking wheels rotate synchronously so that they drive the two positioning wheels to rotate synchronously through the interlocking belt. At this time, because the positioning seat is connected to the vertical part of the interlocking belt, the positioning seat can slide along the height direction of the frame, that is, drive the cache plate to slide along the height direction of the frame, and realize the synchronous sliding of the two cache plates through the transmission rod, thereby improving the synchronous sliding accuracy and sliding efficiency of the two cache plates, avoiding the tilting of the plate-like material between the two cache plates, and the setting of a single servo motor and a single transmission rod realizes the synchronous shifting of the two cache plates. Compared with the technology of setting two cylinders in the prior art, this technology reduces cost expenditure and space occupancy, and at the same time improves the transmission efficiency. The efficiency is higher and the noise is lower; in the above technology, the linkage belt is divided into a vertical part and a horizontal part. In order to ensure the relative verticality of the vertical part and the horizontal part, a guide wheel assembly that cooperates with the linkage belt body can be provided at the junction of the vertical part and the horizontal part. In the above technology, the linkage belt body part between the linkage wheel and the positioning wheel at the top of the positioning plate is the horizontal part, and the linkage belt body part between the two positioning wheels is the vertical part; in the above technology, in order to realize the directional sliding of the positioning seat, a linear guide rail can be provided on the positioning plate, that is, the linear guide rail is provided to cooperate with the positioning seat to realize the directional sliding of the positioning seat and avoid excessive force on the linkage belt. The linear guide rail is an existing technology, so its structure and function will not be described in detail; in the above technology, the transmission rod can be a hexagonal rod according to actual production and assembly requirements, and transmission is realized by the cooperation of the hexagonal rod and the hexagonal nut.
[0008] The utility model is further provided with: one end of any one of the transmission rods passes through the matching hole and is coaxially provided with a matching gear; the servo motor is provided on the frame; a transmission belt is provided between the servo motor and the matching gear.
[0009] The benefit of adopting the above technical solution is that: the servo motor starts the rotation of its output end and drives the matching gear to operate synchronously through the transmission belt, thereby realizing the rotation of the transmission rod, so that the transmission rod cooperates with the positioning seat, linkage belt and positioning wheel to realize the synchronous sliding of the two cache plates.
[0010] The utility model is further configured as follows: two adjustment plates are relatively arranged on the frame, two ball screws are rotatably connected between the two adjustment plates, the two ball screws are relatively arranged, the ball screws are composed of a screw and a sliding seat that cooperates with the screw and slides along the length direction of the screw, the two sliding seats are connected to any one of the positioning plates, a synchronous chain is chain-driven between the starting ends of the two screws, and a rotating wheel is provided at the starting end of any one of the screws.
[0011] The benefits of adopting the above technical solution are: the operator rotates the screw connected to the wheel by rotating the wheel, and a synchronous chain is transmitted between the two screws, so that the two screws rotate synchronously, and the synchronous rotation of the two screws drives the two sliding seats to slide synchronously, that is, the sliding seat slides on the screw along the length direction of the screw, and then the positioning plate connected to the two sliding seats can slide along the length direction of the screw, thereby realizing the adjustment of the distance between the two cache plates.
[0012] The utility model is further provided with: the cache plate is provided with an operating groove along its height direction, each of the support blocks is provided with a through hole along its axial direction, a rotating shaft is rotatably provided in each of the through holes, each of the rotating shafts is inserted into the operating groove and is provided with a small gear, each of the through holes is connected to the operating groove, a notch connected to the through hole is provided at the bottom of the support block, a pressure head is swingably provided in the notch, the starting end of the pressure head is provided to pass through the notch, the end of the pressure head is provided to pass into the through hole and is connected to the starting end of the rotating shaft, a slide is provided in the operating groove to slide along the height direction of the cache plate, the slide is provided with a tooth groove along its height direction, several of the small gears are engaged with the tooth groove, an electric push rod is provided on the cache plate to drive the slide to slide along the height direction of the operating groove so that several pressure heads swing synchronously and contact the material surface, and the pressure head is the fixing part.
[0013] The benefits of adopting the above technical solution are: in the above technology, when the plate-like material gradually progresses between the two cache plates until the plate-like material is plugged into the cache slot, the electric push rod moves down and drives the slide plate to slide along the height direction of the cache plate, so that the slide plate drives several small gears to rotate synchronously. At this time, the rotation of the small gears drives the rotating shaft to rotate, so that the pressing head swings in the gap, that is, the pressing head does not contact the plate-like material before it swings, and contacts the surface of the plate-like material after it swings, thereby realizing the pressure of the pressing head on the plate-like material, thereby realizing the limiting fixation of the plate-like material, ensuring that the plate-like material will not shake or offset between the two cache plates or collide with the cache plate when the cache plate slides subsequently. The phenomenon of collision is prevented, so as to ensure the integrity of the plate-like material and further reduce the damage to the plate-like material. When the new plate-like material needs to be placed in the buffer slot after the sliding plate slides, the electric push rod drives the slide plate to move in the opposite direction to reset the pressure head, that is, the pressure head no longer presses the plate-like material cached on the buffer plate, so that the new plate-like material is not limited by the pressure head and can enter the buffer slot smoothly, thereby avoiding the restriction when the new plate-like material is placed in the buffer slot; in the above technology, according to actual production needs and material needs, only the two groups of support blocks close to the two side walls of the buffer plate are provided with rotating shafts and pressure heads, that is, the support blocks in the middle area of the buffer plate are not provided with pressure heads and rotating shafts, thereby reducing cost expenditure.
[0014] The utility model is further configured that: the end portion of the compression head is made of elastic rubber material, and the tail portion of the compression head is made of metal material.
[0015] The benefits of adopting the above technical solution are: in the above technology, the end of the compression head is made of elastic rubber material, so that when it abuts against the plate material, it will not impose a hard load on the plate material, thereby reducing the pressure on the plate material. At the same time, the end of the compression head has elasticity so that it can deform when facing plate materials of different thicknesses and always be in contact with the plate material, thereby improving the adaptation range, and the tail of the compression head is made of metal material to ensure the smooth swing of the compression head.
[0016] The utility model is further configured that: the notch is opened from the side wall of the support block to the bottom of the support block.
[0017] The benefit of adopting the above technical solution is that: in the above technology, the gap is opened from the side wall of the support block to the bottom of the support block, so that the pressure head has a larger swing angle, that is, the distance between the pressure head and the plate material increases with the increase of the swing angle, thereby adapting to plate materials of different thicknesses.
