(5) УСТРОЙСТВО дл ТРАНСПОРТИРОВКИ ИЗДЕЛИЙ(5) PRODUCT TRANSPORTATION DEVICE

Изобретение относитс к транспорт рующим устройствам с грузонесущими поверхност ми. Оно может быть использовано, напр мер, дл транспортировки плоских под ложек в туннельных печах, в которых производ т различные технологические операции, такие как нанесение на под ложку токопровод щих пленок, отжиг, спекание и др. В насто щее врем транспортирование различных изделий и материалов в туннельных печах как в отечественном производстве, так и за рубежом осуществл ют различными транспортиру ющими устройствами с гибким т говым элементом Cl. К недостаткам перечисленных технических решений следует отнести то, что в устройствах с несколькими ступен ми транспортировки на каждой из них используютс свои автономные гибкие т говые элементы. Наличие нескольких т говых элементов в одном транспортирующем устройстве снижает надежность работы и ухудшает услови его эксплуатации. Другими словами, чем больше узлов, тем менее надежно работает устройство . Наличие автономных гибких т говых элементов на каждой ступени не позвол ет осуществить их нат жение без дополнительных затрат. Как правило требуетс установка нат жных элементов (роликов и устройств), что также увеличивает количество узлов в устройстве, а следовательно, снижает надежность эксплуатации устройства . Наличие самосто тельных несущей и съемной ступеней усложн ет регулирование их подъема и наклона относительно друг друга. Известно транспортирующее устройство , содержащее несущую и съемную ступени гибкого т гового элементаThe invention relates to transport devices with load carrying surfaces. It can be used, for example, to transport flat substrates in tunnel kilns in which various technological operations are carried out, such as applying conductive films to the substrate, annealing, sintering, etc. At present, the transportation of various products and materials in tunnel kilns, both domestically and abroad, they are carried out by various conveying devices with a flexible coupling element Cl. The disadvantages of the listed technical solutions include the fact that in devices with several transport stages, each of them uses its own autonomous flexible traction elements. The presence of several traction elements in one transport device reduces the reliability of work and worsens the conditions of its operation. In other words, the more nodes, the less reliable the device. The presence of autonomous flexible traction elements at each step does not allow them to be tensioned at no additional cost. As a rule, the installation of tensioning elements (rollers and devices) is required, which also increases the number of nodes in the device and, therefore, reduces the reliability of the device operation. The presence of independent carrier and removable steps makes it difficult to regulate their lift and tilt relative to each other. A transport device is known, comprising a carrier and removable stages of a flexible traction member.

Недостатком этого транспортирующего устройства вл етс то, что наличие несущей и съемной ступени двухступенчатого транспортирующего устройства и нат жени роликов усложн ет независимое регулирование высоты, наклона несущей и съемной ступеней и снижает надежность эксплуатации устройства.The disadvantage of this transporting device is that the presence of the carrier and removable stages of the two-stage transporting device and the tension of the rollers complicates the independent adjustment of the height, inclination of the carrier and removable stages and reduces the reliability of operation of the device.

Устройство снабжено прижимным устройством в виде роликов 9 и 10 с пружинами 11. Гибкий т говый элемент 3 с размещенными на нем подлож ками 12 пропущен через канал туннел ной печи 13, в котором, одновременно пропущена и нить-дозатор 14, испар ща вещество,- необходимое дл получени на подложках токопровод щей пленки. К несущей ветви 1 следует отнести гибкий т говый элемент, расположенный от гребенки 4 до гребенки 5. К съемной ветви 2 следует отнести гибкий т говый элемент, раеThe purpose of the invention is to increase the reliability of operation of the device by improving the regulation of the carrier and removable steps of the flexible t-element. The goal is achieved by the fact that a device for transporting products, containing a carrier and removable stages of a flexible traction element passed through the combs, a driving drum and guide rollers, is provided with a clamping device, executed in the form of two coaxially arranged rollers of different diameters with springs interacting From the bar, a two-stage ban is made, with the carrier and removable stages of the device formed by a single flexible traction element. FIG. 1 shows the proposed device transporting a flexible traction element of the substrate into a tunnel kiln, a general view of FIG. 5 in FIG. 2 kinematic scheme of the device transporting the substrate; in fig. device view from above. The device for transporting products contains a carrier 1 and a removable 2 stages of a flexible traction element 3 (two siliceous twisted yarns) passed through the combs 4 and 5, a drum b with two surfaces a and b, guide rollers 7 and 8. The device is equipped with a pressure a device in the form of rollers 9 and 10 with springs 11. A flexible traction element 3 with substrates 12 placed on it is passed through a channel of a tunnel kiln 13, in which, at the same time, the metering filler 14, the evaporated substance, is also needed to obtain on substrates of conductive galaxy ki. The flexible traction element located from the comb 4 to the comb 5 should be attributed to the carrier branch 1. The flexible traction element should be assigned to the removable branch 2, para

Claims

A flexible traction element 3 supported by combs 4 and 5 with substrates located on it is passed through a tunnel kiln 13. The combs L and 5 determine and regulate the distance between the metering filaments 14 and the flexible traction element 3, as well as between the two (silica) filaments of the flexible traction element 3 (Fig. 3). Further, the flexible traction element 3 bends around the side surfaces 6 of the drum 6 and presses the spring 11 against them through the roller, then bends around the guide rollers 7 and 8, which determine its angle of inclination. The flexible traction element 3 is passed between the surface a of the drum b and the roller 10, pressing the latter with a spring 11. The substrates 12 pass the tunnel furnace 13, from the carrier stage 1 are transferred to the removable stage 2 of the flexible traction element 3, to the guide roller 8 and further on dumping, in tare (not shown on the drawing). Flexible coupling element 3 can be infinite (not shown on the drawing). When the combs 4 and 5 are raised or one of them rises, the carrier level 1 of the flexible TRACTOR element 3 in the tunnel furnace 13 rises or tilts, i.e. The height and inclination of the carrier stage 1 are regulated independently of the removable stage 2, which can remain in the same position. When lifting the guide rollers 7 and 8 or one of them, the removable stage 2 of the flexible connecting element 3, i.e. The height and inclination of the detachable stage 2 is regulated independently of the carrier stage 1. Such adjustment of the carrier and removable stages is ensured by the fact that the flexible traction element is made uniform. This ultimately simplifies the regulation of the carrier and removable steps in height and tilt, makes the adjustment more flexible and thereby increases the efficiency of the device as a whole. In addition, in the device, the tension of the flexible traction element 3 in the removable stage 2 is carried out automatically. Due to the difference of the linear velocities of the surfaces c and b of the drum 6, the speed of the flexible traction element 3 at the removable stage 2 increases with respect to the speed of movement of the flexible traction element 3 at the carrier stage 1 within the elastic properties of the flexible traction element 3. The effect of the invention is that due to the difference in the diameters of the surfaces of the drum quince and the interaction of the latter with the rollers of the respective diameters of the drum, a constant tension is removed tupeni flexible t-bar element, which allows to exclude such a structural element as a tension roller or device, and, consequently, improve the efficiency of the device, Due to the fact that the flexible traction element is designed as a single unit, the number of nodes decreases, Independent adjustment of the slope and height of the steps of the flexible traction element relative to each other is improved. This enhances the usability and efficiency of the conveying device. The economy of one transport device 12 f according to preliminary estimates may be about 5 thousand rubles. in year.
