Abstract
Description
Technical Field
[0001] The utility model relates to material conveying equipment, in particular to a precise positioning and conveying system for thin sheet materials. Background Art
[0002] Vibrating plates are a common material conveying device in the field of mechanical equipment. For some scenarios where materials need to be accurately conveyed to a predetermined location and multiple materials need to be accurately conveyed to the predetermined location at the same time, conventional vibrating plates cannot achieve this process.
[0003] For example, the circular saw blade used for stone cutting is made by stacking multiple blades of different materials and 1mm thick together, and then hot pressing them to produce an integrated blade head.
[0004] Currently, the above blades are placed one by one in the mold manually. The mold usually has 12 or 16 cavities. Each cavity holds a different number of blades according to different cutter head requirements. Putting them in manually one by one is not only inefficient, but sometimes blades are missed in some cavities, resulting in the produced cutter heads not meeting quality requirements. Summary of the invention
[0005] In view of this, it is necessary to provide a sheet material precise positioning and conveying system with high production efficiency, simple structure and convenient use.
[0006] In order to solve the above technical problems, the technical solution of the utility model is: a sheet material accurate positioning and conveying system, comprising:
[0007] A vibrating conveying part, wherein a linear feeder is connected to the bottom of the vibrating conveying part, and a plurality of parallel straight grooves for conveying sheet materials are provided on the top of the vibrating conveying part;
[0008] A feeding part, wherein the feeding part has a storage trough having the same number as the straight troughs and used for storing thin-sheet materials, and each straight trough is provided with a storage trough at the front end thereof, and the axial direction of the storage trough is perpendicular to the axial direction of the straight trough;
[0009] A limiting part, wherein the limiting part comprises a plurality of limiting rods with lifting functions, wherein the limiting rods are arranged at intervals at the inner rear end of the straight groove, and when the limiting rods are lowered to the bottom, the top ends of the limiting rods are located below the inner bottom surface of the straight groove, and when the limiting rods are raised to the top, the limiting rods restrict the sheet material from continuing to move along the straight groove;
[0010] A first sensor is installed on the bottom surface of the straight groove between two adjacent limit rods in the same straight groove, and the first sensor is used to detect whether the sheet material exists.
[0011] Furthermore, it also includes a pushing portion, which is fixedly connected to the front end of the straight groove and is used to push the thin film material at the bottom of the storage groove into the straight groove.
[0012] Furthermore, a silo for storing thin-sheet materials is inserted into the storage trough, and the thin-sheet materials can move axially along the silo.
[0013] Furthermore, a first cylinder for driving the limiting rod to be lifted or lowered is fixedly connected to the bottom of the rear end of the straight groove.
[0014] Furthermore, the pushing portion includes a second cylinder and a pushing block fixedly connected to the piston rod of the second cylinder, and the pushing block is used to push the thin sheet material away from the bottom of the storage trough and into the straight trough.
[0015] Furthermore, a detection part is fixedly connected to the vibrating conveying part behind the feeding part, and the pushing part pushes the thin film material into the straight groove below the detection part. The detection part has second sensors whose number is equal to the straight grooves, and the second sensors are used to detect whether there is thin film material in the straight groove below the detection part.
[0016] Furthermore, a liftable push rod is fixedly connected to the bottom of the straight trough below the storage trough. When the push rod is lowered to the bottom, it does not hinder the movement of the thin film material in the straight trough. When the push rod is raised to the top, the push rod is inserted into the silo.
[0017] Furthermore, a third cylinder for driving the push rod to rise and fall is fixedly connected below the straight groove.
[0018] Furthermore, a limiting rod is fixedly connected above the straight groove to limit the moving thin sheet material.
[0019] Furthermore, the limiting rod is liftably connected above the straight slot.
[0020] Compared with the prior art, the utility model has the following beneficial effects: the device can quickly and accurately convey the sheet material to a predetermined position, and keep it at the predetermined position without moving.

DETAILED DESCRIPTION
[0027] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.
[0028] like Figure 1-4 As shown, a thin sheet material accurate positioning and conveying system comprises: a vibrating conveying part 1, a feeding part 3, a pushing part and a limiting part. The thin sheet material in the device is illustrated by a blade, especially a blade of a circular saw blade head for stone cutting. The blade head is sintered by multiple blades, and the thickness of the blade is 1mm. The mold for sintering the blade head usually has 16 cavities, which can hold 16 blade heads. Therefore, the device can provide 16 blades to the mold at one time.
[0029] In the following embodiments, "thin sheet material" is replaced by "blade".
[0030] A linear feeder 2 is connected to the bottom of the vibrating conveying part 1, and four parallel straight grooves 11 are provided on the top of the vibrating conveying part 1 for conveying blades; the ends of the straight grooves 11 are closed to prevent the blades from being separated from the straight grooves 11 when conveyed to the ends of the straight grooves 11.
[0031] The feed section 3 has four storage troughs 31 for storing thin sheet materials. Each straight slot 11 is provided with a storage trough 31 at the front end, and the axial direction of the storage trough 31 is perpendicular to the axial direction of the straight slot 11. Of course, the capacity of the storage trough 31 is relatively small, and can only store 2 to 30 blades. For the high-speed operation of the device, this storage capacity cannot meet the production needs. Therefore, in this embodiment, a silo 4 for storing blades is inserted into the storage trough 31, and the blades can move axially along the silo 4. The height of the silo 4 is usually designed to be 750mm, and more than 700 blades can be stored inside it, which can meet the supply of the device for 1-2 hours of operation.
[0032] In order to facilitate the installation of blades in the silo 4, a liftable push rod 9 is fixedly connected to the bottom of the straight groove below the storage trough 31, and a third cylinder 91 for driving the push rod 9 to rise and fall is fixedly connected below the straight groove 11. When the push rod 9 is lowered to the bottom, it does not hinder the movement of the blade in the straight groove 11. When the push rod 9 is raised to the top, the push rod 9 is inserted into the silo 4, and then the blade is dropped into the silo 4. At the same time, the push rod 9 supports the blade and slowly descends; to avoid the blade from deflecting when entering the silo 4 and causing the silo 4 to get stuck when there is no push rod 9.
[0033] The limiting part includes a plurality of limiting rods 7 with lifting functions, and a first cylinder 71 driving the limiting rod 7 to lift is fixedly connected to the bottom of the rear end of the straight groove 11. The limiting rods 7 are arranged at intervals at the inner rear end of the straight groove 11, and the rear end of each straight groove 11 has three limiting rods 7 distributed at intervals (if the end of the straight groove is not closed, four limiting rods are required). When the limiting rod 7 is lowered to the bottom, the top of the limiting rod 7 is located below the bottom surface of the straight groove (does not hinder the blade from moving along the straight groove). When the limiting rod is raised to the top, the limiting rod 7 limits the blade from continuing to move along the straight groove 11.
[0034] In the same straight groove 11, a first sensor 12 is installed on the bottom surface of the straight groove between two adjacent limit rods 7, and the first sensor 12 is used to detect whether a blade exists between the two limit rods 7. Of course, in this embodiment, the end of the straight groove 11 is closed, so the first sensor 12 is also arranged between the end of the straight groove 11 and the adjacent limit rod 7.
[0035] The limit rod 7 on the straight groove 11 is in the state of being dropped to the bottom in the initial state, and cannot hinder the movement of the blade along the straight groove; the first sensor 12 is arranged on the inner bottom surface of the straight groove and is not exposed from the inner bottom surface of the straight groove. When the first sensor 12 detects the presence of a blade above it, the limit rods at both ends of the first sensor 12 rise, which not only limits the movement of the blade at this location by the two limit rods (if the end of the straight groove is closed, then it is the end of the straight groove and the adjacent limit rod), but also prevents subsequent blades from entering this area, ensuring that there is one and only one blade between two adjacent limit rods.
[0036] The pusher is fixedly connected to the front end of the straight groove, and is used to push the blade at the bottom of the storage groove 31 into the straight groove. The pusher includes a second cylinder 5 and a pusher block 51 fixedly connected to the piston rod of the second cylinder. The pusher block 51 is used to push the blade away from the bottom of the storage groove and into the straight groove. When the pusher block is pushed out, the blade at the bottom of the storage groove can be pushed into the straight groove. When the pusher block is retracted, the space at the bottom of the storage groove is avoided, and the blade can fall normally from the bottom of the storage groove.
[0037] In order to control the operation timing of the second cylinder 5, that is, when the push block should be pushed out and when the push block should be retracted, a detection part 6 is fixedly connected to the vibrating conveying part behind the feeding part. The pushing part pushes the blade into the straight groove below the detection part 6. The detection part 6 has second sensors 61 equal to the number of the straight grooves. The inner bottom surface of the straight groove there is a groove for placing the second sensor 61. The second sensor 61 is not exposed from the inner bottom surface of the straight groove. When the second sensor detects that there is no blade above it, the second cylinder drives the push block to operate and push the blade out from the bottom of the storage trough into the straight groove, and then the second cylinder immediately drives the push block to retract.
[0038] In this embodiment, in order to prevent the blade from jumping out of the straight groove due to excessive amplitude during the straight groove movement, and from being stuck in the straight groove due to excessive vibration amplitude, a fixing frame 8 is fixedly connected above the straight groove section between the detection part and the limiting part, and a limiting rod 81 with a limiting function is connected to the fixing frame 8 in a lifting manner to limit the moving blade. The limiting rod 81 is connected to the inner upper part of the straight groove 11 in a lifting manner, and the gap between the bottom surface of the limiting rod 81 and the inner bottom surface of the straight groove is slightly larger than the thickness of the blade.
[0039] When the 16 blades at the end of the straight groove have arrived at the predetermined position, a robot transfers the 16 blades to the mold of the sintered blade head, and then the limit rod retracts to continue the process of conveying the blades to the predetermined position.
[0040] The working process of this device is as follows:
[0041] Add materials, the push rod rises, and then add blades to the hopper until the hopper is full of blades. During the blade loading process, the push rod supports the blades and slowly descends.
[0042] During feeding, before the blade enters the straight groove, the limit rods are in a retracted state and do not hinder the blade from moving in the straight groove; when the second sensor detects that there is no blade above it, the second cylinder at the front end of the straight groove quickly pushes the push block to push the blade at the bottom of the storage trough into the straight groove, and the blade moves along the straight groove under the vibration of the linear feeder.
[0043] When the blade moves to between two adjacent limiting rods, when the first sensor there detects the presence of the blade above it, the limiting rods at both ends of the first sensor rise.
[0044] When all 16 blades are transported to the predetermined positions, a robot transfers the 16 blades to the mold of the sintered blade head, and then the limit rod is retracted to start the process of continuing to transport the blades to the predetermined positions.
[0045] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
