Предварительная ориентация кромок 5 осуществляется специальным механизмом ориентации, что усложняет конструкцию устройства.The preliminary orientation of the edges 5 is carried out by a special orientation mechanism, which complicates the design of the device.

Целью изобретения является упрощение конструкции устройства за счет исклю10 чения механизма предварительной ориентации кромок.The aim of the invention is to simplify the design of the device by eliminating the mechanism of preliminary orientation of the edges.

Указанная цель достигается тем, что в устройстве, содержащем стыковочный 15 транспортер, механизмы для отбора с транспортера диагон а льно-резательной машины закроенных полос и их стыковки, осветитель и установленный под стыковочным транспортером фотоэлемент, согласно 20 изобретению, осветитель установлен под транспортером диагонально-резательной машины на одном уровне с фотоэлементом, а напротив осветителя над этим же транспортером смонтировано с возможностью поворота проекционное зеркало.This goal is achieved by the fact that in the device containing the docking conveyor 15, mechanisms for selecting from the conveyor a diagonal flax cutting machine of closed strips and their joining, a illuminator and a photocell installed under the docking conveyor, according to the invention, the illuminator is installed under the diagonal-cutting conveyor the machines are on the same level as the photocell, and opposite the illuminator above the same conveyor, a projection mirror is mounted with the possibility of rotation.

На фиг. 1 изображено предлагаемое устройство, общий вид, в плане; на фиг. 2 —разрез А—А фиг. 1; на фиг. 3 — раз30 ,рез Б—Б фиг. 2.In FIG. 1 shows the proposed device, General view, in plan; in FIG. 2 — section A — A of FIG. 1; in FIG. 3 - times30, res B — B of FIG. 2.

Устройство содержит четырехбарабанный ремешковый транспортер 7 диагонально-резательной машины (на чертежах не показана), ремешковый стыковочный транспортер 2, установленный по отношению к транспортеру 1 диагонально-резательной машины под углом, равным углу раскроя полос, и механизмы (на чертежах не показаны) для отбора с транспортера 1 закроенных полос и их стыковки.The device comprises a four-drum strap conveyor 7 of a diagonal cutting machine (not shown in the drawings), a strap docking conveyor 2, mounted in relation to the conveyor 1 of the diagonal cutting machine at an angle equal to the angle of cutting of the strips, and mechanisms (not shown in the drawings) for selection from the conveyor 1 closed strips and their docking.

.Под транспортером 1 между двумя смежными барабанами 3, 4 установлен осветитель 5 для проецирования кромки полосы на проекционное зеркало 6, смонтированное .над транспортером 1 напротив осветителя 5. Зеркало 6 выполнено поворотным с помощью винта 7. Между ремешками стыковочного транспортера 2 на одном уровне с осветителем 5 размещен фотоэлемент 8, предназначенный для останова стыковочного транспортера 2. Ширина фотоэлемента 8 такая же, как и ширина осветителя 5..By the conveyor 1 between two adjacent drums 3, 4 a illuminator 5 is installed for projecting the edge of the strip onto a projection mirror 6 mounted above the conveyor 1 opposite the illuminator 5. The mirror 6 is made rotatable with a screw 7. Between the straps of the docking conveyor 2 at the same level as illuminator 5 is placed photocell 8, designed to stop the docking conveyor 2. The width of the photocell 8 is the same as the width of the illuminator 5.

Устройство работает следующим образом. !The device operates as follows. !

С остановившегося транспортера 1 закроенную полосу 9 известным способом, например, с помощью связанных с пневмоцилиндрами (на чертежах не показаны) и перемещающихся по направляющим (на чертежах не показаны) вакуум-присосок (на чертежах не показаны) перемещают и опускают'на остановившийся стыковочный транспортер 2, луч света при этом не попадает ,на фотоэлемент 8. Затем включается стыковочный транспортер 2 <и останавливается он тогда, когда луч света ют осветителя 5, показывающий положение боковой кромки полосы 9 на транспортере 1 я отраженный поворотным зеркалом 6, попадает .на фотоэлемент 8, т. е. когда проекции крсмки закроенной полосы 9, лежащей на транспортере 1, и конца состыкованного полотна, лежащего на стыковочном транспортере 2, совпадут на фотоэлементе 8. Затем снова на остановившийся стыковочный транспортер подают закроенную полосу 9 и опускают на конец полотна 10 с перехлестом, равньпм расстоянию в плане между стыкуемой кромкой закроенной полосы 9 и ее проекции на фотоэлементе |8.From the stopped conveyor 1, the closed strip 9 in a known manner, for example, using a suction cup (not shown) connected with pneumatic cylinders (not shown in the drawings) and moving along the guides (not shown in the drawings) and lower the docking conveyor to a stopped 2, the light beam does not fall on the photocell 8. Then, the docking conveyor 2 <is turned on and it stops when the light beam is illuminated 5, showing the position of the lateral edge of the strip 9 on the conveyor 1 reflected with the turning mirror 6, it hits the photocell 8, that is, when the projection of the closed strip 9 lying on the conveyor 1 and the end of the docked web lying on the docking conveyor 2 coincide on the photocell 8. Then, the closed docking conveyor is again fed with the closed strip 9 and lowered to the end of the sheet 10 with an overlap equal to the distance in plan between the abutting edge of the closed strip 9 and its projection on the photocell | 8.

'Смещая проекцию кромки закроенной полосы 9 ла фотоэлементе 8 относительно положения кромки закроенной полосы 9 в плане на транспортере 1 диагонально-резательной машины поворотом зеркала 6 с помощью винта 7, меняют место останова конца полотна 10 и получают требуемую величину нахлеста.'By shifting the projection of the edge of the closed strip 9 to the photocell 8 relative to the position of the edge of the closed strip 9 in plan view on the conveyor 1 of the diagonal cutting machine by turning the mirror 6 with the screw 7, the stop position of the end of the web 10 is changed and the required overlap value is obtained.

Применение предлагаемого устройства позволит при простоте конструкции обеспечить постоянную ширину стыка полос на стыковочном транспортере независимо от положения полос на транспортере диагонально-резательной машины, а также уменьшить расход корда за счет сокращения разброса ширины стыка.The application of the proposed device will allow for simplicity of design to ensure a constant width of the strip junction on the dock conveyor, regardless of the strip position on the diagonal cutting machine conveyor, as well as to reduce cord consumption by reducing the spread of the joint width.
