Device for transporting thin-walled and fragile products
(57) Abstract:Usage: refers to a device for conveying thin-walled and fragile products. The inventive device for transporting thin-walled and fragile products contains placed in a controlled magnetic field and is made of elastic thin-walled material sealed camera to capture product, installed on a support for movement with the product and placed in a sealed chamber ferromagnetic liquid. The volume of the sealed chamber more than the amount of ferromagnetic fluid. An airtight chamber is fixed to the upper part on the support with the possibility of sagging under the action of ferrofluids. 2 Il. The invention relates to mechanical engineering and can be used for secure and quick fastening and transportation of products of different shapes and weights.Famous capture of an industrial robot containing sponges, each of which is made in the form of a cylinder of thin-walled elastic material and filled with loose granular material, which introduced the ferromagnetic component, and the sponge is equipped with an electromagnetic winding, (ed.St. N 629058). is, containing placed in a controlled magnetic field and is made of elastic thin-walled material sealed chamber (sponge) to capture products that are installed on the support for movement with the product and placed in sealed chambers ferromagnetic liquid  the Disadvantages of these devices are available in designs with multiple, two sealed chambers (sponges) and drive to move them, which complicates the design and reduces performance due to the need to move the jaws in the capture of the product. In addition, performance will lead the process of adjusting devices on each product during transportation of customized, small-scale and original products. In addition, when capturing the fragile complex-shaped products may damage them, because the process of grasping and fixation products are original mechanical convergence of the jaws and forced squeezing their products. The form of the sealed chambers in the form of the jaws may not always provide uniform capture complex products, which may lead to decrease in the reliability of the commit.The purpose of the invention to simplify the design of the device.This is achieved by the fact that the device is e and is made of elastic thin-walled material sealed camera to capture products mounted on the support for movement with the product, and is located in a sealed chamber ferromagnetic liquid, the volume of the sealed chamber more than the amount of ferromagnetic fluid, while the airtight chamber is fixed to the upper part on the support with the possibility of sagging under the action of ferrofluids.In Fig. 1 presents the proposed device, a General view of Fig. 2 the device in the working position at the time of transportation of the product.The device comprises a sealed chamber 1 made of thin elastic material, and the volume of the sealed chamber 1 exceeds the volume of the ferromagnetic fluid 2 filling the sealed chamber 1, the device 3 to create controlled magnetic fields, for example a solenoid, a support 4 on which the airtight chamber 1 is fixed to the upper part can move with it and sagging under the action of ferrofluids, in addition, the device 3 to generate controlled magnetic field also has the ability to move together with the support, the energy source 5, the product is shaped profile 6, the tube 7 for closing openings in a sealed chamber.The device operates as follows. Freely when hidcote 2. When lowering device for the product 6 which is in a sealed chamber ferromagnetic liquid 2 under the action of its weight will be free to flow around the product 6. Due to this, the surface area of the product in contact with the surface of the elastic thin-walled sealed chamber increases, which will lead to a more uniform distribution of effort of grip on the surface of the product, and therefore to a more reliable fixing it and at the same time reduces the likelihood of mechanical damage to fragile products. When high elasticity sealed chamber allows partial penetration of it into the internal cavity of the product (Fig. 2) that will allow to improve the product and the internal cavity, which is not always possible in the prototype.When the product will be in contact with the surface of the sealed chamber from the power source 5 to the device 3 to create controlled magnetic fields, such as a solenoid, is current. Ferromagnetic liquid 2 in a sealed chamber, the magnetic field of the solenoid hardens. Further mounted on a support 4 sealed Luggage together with retained product is lifted and transported to the desired location. Then the current is turned off. The ferromagnetic fluid in the prototype of the device is simple to manufacture, the operation and repair, it lacks many of the mechanical parts and components, which makes the device more reliable and does not require large expenditures.In the proposed device due to the larger volume of the sealed chamber in comparison with the amount of ferromagnetic fluid can last longer move freely inside the chamber without stretching excessively, it is better to retain the elastic thin-walled shell and increase durability. In addition, unlike the prototype, the device will require no adjustment for the flow sealed camera products, whether serial, series, or original products, which will increase its performance.Thus, the proposed device will provide reliable fixation of the product without damaging it, i.e. meets its purpose: transportation of thin-walled and fragile items, as well as products of complex shape. DEVICE FOR TRANSPORTING THIN-walled AND FRAGILE PRODUCTS containing placed in a controlled magnetic field and is made of elastic thin-walled material sealed camera to capture product, installed on a support for movement with the product, and respoi amount of ferromagnetic fluid, this airtight chamber is fixed to the upper part on the support with the possibility of sagging under the action of ferrofluids.
