Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machines, in particular to a material stacking height detection device for a material unloading platform and a material tower. Background Art

[0002] Fiber laser cutting machine is a very common sheet metal processing machine tool. Nowadays, it is developing very rapidly, and its sales volume is increasing year by year. More and more production and processing factories are using fiber laser cutting machine as an efficient and stable sheet metal processing tool. And the material tower, as an automated auxiliary loading and unloading machine tool for laser cutting machine, is also increasingly accepted and used by users.

[0003] The material tower is an automated auxiliary machine tool device used in conjunction with a laser cutting machine, which integrates material storage and automatic loading and unloading. It has the characteristics of small footprint, large capacity, high loading and unloading efficiency, and high safety.

[0004] The material tower stores plates of different sizes, thicknesses, and materials in the material warehouse, and saves the plate information stored in the material warehouse in the system. When the laser cutting machine selects a plate for processing, the material tower will automatically place the selected plate from the material warehouse onto the cutting table of the laser cutting machine for processing. After the processing is completed, the material tower will automatically place the completed processed plate onto the unloading tray where the finished product is stored. The entire loading and unloading process does not require human intervention and is fully automated.

[0005] After the material tower executes loading and unloading cycles many times, the height of the finished materials piled up on the unloading platform will become higher and higher as the number of finished products unloaded increases. At this time, there is a risk of the material fork colliding with the finished materials on the unloading platform when entering the unloading platform. Therefore, a device for detecting the material height of the unloading platform is used to avoid the collision between the material fork and the finished materials on the unloading platform, thereby causing unnecessary losses. Summary of the invention

[0006] The purpose of the utility model is to solve the problems existing in the above-mentioned prior art and to provide a material stacking height detection device for a material unloading platform and a material tower.

[0007] The specific scheme of the utility model is: a device for detecting the height of the material pile on the unloading platform, including a mounting frame arranged on one side of the material fork shaft, a laser scanner sensor is installed at the bottom of the mounting frame, the laser scanner sensor is connected to the control system signal of the host, the laser scanner sensor is used to detect the height of the material pile on the unloading platform in real time and send the detection data signal to the control system, the top of the mounting frame is connected to the material fork shaft through an adjustable top screw A, and a fixed bottom plate is provided at the bottom of the mounting frame, the laser scanner sensor is installed at the bottom of a horizontal adjustment plate, and the horizontal adjustment plate and the fixed bottom plate are connected by multiple adjustable top screws B.

[0008] Furthermore, the level adjustment plate is connected to the middle part of the fixed base plate via a bolt, and a spring is installed between the nut of the bolt and the fixed base plate.

[0009] Furthermore, a protective cover is provided on the outside of the mounting frame.

[0010] Furthermore, a mounting block is provided on the material fork shaft corresponding to the mounting frame, and a side plate is provided on each side of the mounting frame. The side plates are provided with waist-shaped holes arranged in the vertical direction, and guide screws are installed in the waist-shaped holes. The mounting frame is connected to the mounting block through the guide screws.

[0011] Furthermore, the utility model also provides a material tower, including a material fork and a material unloading platform, and the above-mentioned detection device is installed in the middle of the material fork shaft.

[0012] Compared with the existing technology, the utility model has the following advantages: 1. Large detection range. When the material fork is ready to unload materials on the unloading platform, the material fork can sense the height of the finished materials on the unloading platform before entering the unloading platform area. If the finished materials on the unloading platform are too high, the material fork height can be known in advance and increased to prevent the material fork from colliding with the finished materials, thereby avoiding the finished materials or equipment from being damaged; 2. High detection accuracy. Regardless of the shape or size of the finished materials, the laser scanner sensor can detect whether there are objects blocking the inspection area in time. 3. Flexible adjustment. Through the top screws of various parts in the device, the detection range of the laser scanner sensor can be quickly adjusted to a suitable horizontal plane to achieve the required detection effect.
