Description

Изобретение относится к станкостроению, а более конкретно к устройствам для автоматической загрузки рабочих позиций технологических машин штучными ориентированными изделиями из ферромагнитных и немагнитных материалов типа цилиндров с конусом, с'амозаклйнивающихся конических изделий, тел вращения с переменным сечением по длине, цилиндрических стаканов и т.п., а также изделий с легкоповреждаемой поверхностью.The invention relates to machine tool industry, and more specifically to devices for automatically loading the working positions of technological machines with piece oriented products from ferromagnetic and non-magnetic materials such as cylinders with a cone, self-locking conical products, rotation bodies with a variable length section, cylindrical glasses, etc. ., as well as products with an easily damaged surface.

Целью изобретения является повышение надежности работы устройства путем обеспечения принудительной ориентации изделия.The aim of the invention is to increase the reliability of the device by providing forced orientation of the product.

На фиг. 1 изображено роторное питающее устройство, продольный разрез; на фиг. 2 — то же, при ориентации изделия острым концом вверх; на фиг. 3 — то же, при ориентации изделия острым концом вниз; на фиг. 4 — то же, при ориентации изделия типа конических стаканов дном вниз; на фиг. 5 — то же, при ориентации изделий с легкоповреждающей поверхностью; на фиг. 6 — разрез А—А на фиг. 1.In FIG. 1 shows a rotary feed device, a longitudinal section; in FIG. 2 - the same, with the orientation of the product with the sharp end up; in FIG. 3 - the same, with the orientation of the product with the sharp end down; in FIG. 4 - the same, with the orientation of the product type of conical glasses bottom down; in FIG. 5 - the same, with the orientation of products with a slightly damaging surface; in FIG. 6 is a section A — A in FIG. 1.

Роторное питающее устройство содержит жестко связанный с валом 1 барабан 2, по периферии которого концентрично оси расположены рабочие органы, выполненные в виде захватов 3, управляемых от ползунов (не показаны). Захваты 3 установлены с возможностью возвратно-поступательного перемещения в направляющих отверстиях 4 барабана 2. В каждом направляющем отверстии 4 выполнен вертикальный приемник Д.The rotary feed device comprises a drum 2 rigidly connected to the shaft 1, on the periphery of which the working bodies are arranged concentrically to the axis, made in the form of grippers 3 controlled from sliders (not shown). The grippers 3 are mounted with the possibility of reciprocating movement in the guide holes 4 of the drum 2. In each guide hole 4 is made a vertical receiver D.

Механизм принудительной ориентации 5 оснащен толкателем 6. выполненным, например, в виде диска, который входит в кольцевой паз 7, выполненный по периметру барабана 2 на его внутренней поверхности. При этом геометрическая ось вращения диска расположена в вертикальной плоскости.The forced orientation mechanism 5 is equipped with a pusher 6. made, for example, in the form of a disk, which is included in the annular groove 7, made around the perimeter of the drum 2 on its inner surface. The geometric axis of rotation of the disk is located in a vertical plane.

На боковой поверхности барабана 2 выполнены выпускные окна 8 для выгрузки изделий, число которых соответствует числу рабочих позиций ротора. Над каждым захватом 3 соосно в направляющих 4 установлен подпружиненный пружиной 9 шток 10, в торце которого выполнено центрирующее гнездо 11 под изделие 12, причем торцовая поверхность захватов 3 имеет ориентирующий элемент 13, выполненный либо в виде гнезда, либо в виде штыря.On the side surface of the drum 2 there are made exhaust windows 8 for unloading products, the number of which corresponds to the number of working positions of the rotor. Above each gripper 3 coaxially in the guides 4, a spring 10 spring 10 is installed, at the end of which a centering socket 11 is made for the product 12, the end surface of the grippers 3 having an orienting element 13, either in the form of a socket or in the form of a pin.

Щелевые ориентаторы 14 в устройстве образованы захватами 3 и подпружиненными штоками 10 в крайнем верхнем их положении.Slot orientators 14 in the device are formed by grippers 3 and spring-loaded rods 10 in their extreme upper position.

Для выдачи конических изделий 12 из устройства острым концом вниз щелевые ориентаторы 14 выполнены в выпускных окнах 8 в вертикальных плоскостях, параллельных геометрической оси барабана.To issue conical products 12 from the device with a sharp end down, the slot orientators 14 are made in the outlet windows 8 in vertical planes parallel to the geometric axis of the drum.

Для выдачи конических изделий с легкоповреждаемой поверхностью, например из мягких материалов, в каждое окно для выгрузки изделий 8 (в перпендикулярной плоскости окну для выгрузки изделий 8) установлен механизм принудительной ориентации, толкатель 6 которого выполнен в виде шибера, связанного посредством штанги 15 с приводом возвратно-поступательного перемещения в виде стационарного кулачка 16, по которому обкатывается ролик 17.For the delivery of conical products with an easily damaged surface, for example, from soft materials, a forced orientation mechanism is installed in each window for unloading products 8 (in the perpendicular plane to the window for unloading products 8), the pusher 6 of which is made in the form of a slide connected by a rod 15 to the drive back - translational movement in the form of a stationary cam 16, on which the roller 17 rolls in.

На наружной поверхности барабана 2 установлена жестко с ним связанная звездочка 18 цепного конвейера 19, приемные гнезда 20 которого размещены под выходными каналами наклонных лотков 21.On the outer surface of the drum 2 is mounted rigidly connected to it by an asterisk 18 of the chain conveyor 19, the receiving slots 20 of which are located under the output channels of the inclined trays 21.

Под барабаном 2 размещено устройство подачи 22, например, гнезда 23 цепного конвейера 24.Under the drum 2 there is a feeding device 22, for example, a slot 23 of the chain conveyor 24.

Роторное питающее устройство работает следующим образом.Rotary power device operates as follows.

Изделие 12 из устройства подачи 22, например, гнезда 23 цепного конвейера 24 при вращении приводного вала 1 забирается захватом 3 и принудительно, известным способом, подается в вертикальный приемник 1. выполненный в направляющем отверстии 4.The product 12 from the feed device 22, for example, the nests 23 of the chain conveyor 24, when the drive shaft 1 is rotated, is taken by the gripper 3 and forcibly, in a known manner, is fed to the vertical receiver 1. made in the guide hole 4.

При этом верхний конец изделия 12 входит в гнездо 11 подпружиненного штока 10 (например, коническое для остроконечных изделий) и центрируется вдоль оси приемника Д. Таким образом, оно оказывается одновременно охваченным с двух сторон: с одной стороны захватом 3, а с другой — подпружиненным штоком 10, т.е. последние образуют как бы трафарет, раздвижной вдоль оси изделия.In this case, the upper end of the product 12 enters the socket 11 of the spring-loaded rod 10 (for example, conical for pointed products) and is centered along the axis of the receiver D. Thus, it is simultaneously covered on both sides: on the one hand, by a gripper 3, and on the other, by a spring-loaded stock 10, i.e. the latter form a kind of stencil sliding along the axis of the product.

При дальнейшем совместном перемещении вверх с зажатым с двух сторон изделием 12 подпружиненный шток 10 открывает окно 8 для выгрузки изделий, при этом захват 3 занимает положение, при котором его верхняя кромка несколько выше основания окна 8 для выгрузки изделий.With further joint movement upward with the product 12 clamped on both sides, the spring-loaded rod 10 opens the window 8 for unloading the products, while the gripper 3 occupies a position in which its upper edge is slightly higher than the base of the window 8 for unloading the products.

В результате изделий 12 точно фиксируется в приемнике Д против выпускного окна 8 для выгрузки изделий и перекрывает сквозной боковой паз 7.As a result, the products 12 are precisely fixed in the receiver D against the outlet window 8 for unloading the products and overlaps the through lateral groove 7.

При дальнейшем вращении барабана 2 вертикально зафиксированное в приемнике Д изделие 12 подходит к стационарному механизму принудительной ориентации 5, толкатель 6 которого, например диск, взаимодействует через кольцевой паз 7 с изделием 12.With further rotation of the drum 2, the product 12 vertically fixed in the receiver D approaches the stationary mechanism of forced orientation 5, the pusher 6 of which, for example, the disk, interacts through the annular groove 7 with the product 12.

При этом, в случае необходимости ориентирования конических изделий 12 утолщенным концом вниз, острый конец его (не зависимо от первоначальной ориентации в трафарете — вверх или вниз) удерживается в гнезде 11 подпружиненного штока 10 либо в гнезде 13 захвата 3, а утолщенный конец — не удерживается и или сталкивается с захвата 3 в выпускное окно 8 для выгрузки изделий, или принудительно разворачивается в окне 8 для выгрузки изделий толкателем 6 с опорой изделия 12 острым концом в гнездо 13 захвата 3. При этом цоддействием пружины 9 верхний шток 10 устремляется вниз (в исходное нижнее положение) , и тем самым принудительно осуществляет разворот и разгон изделия 12 (при опоре острым концом в захвате 3), т.е. таким образом сокращается время принудительной ориентации.In this case, if it is necessary to orientate the conical products 12 with the thickened end down, the sharp end thereof (regardless of the initial orientation in the stencil - up or down) is held in the socket 11 of the spring-loaded rod 10 or in the socket 13 of the gripper 3, and the thickened end is not held and either collides with a grab 3 in the outlet window 8 for unloading products, or is forcibly deployed in a window 8 for unloading products with a pusher 6 with the support of the product 12 with a sharp end into the socket 13 of the gripper 3. In this case, by means of the spring 9, the upper rod 10 of the device moves down (to the initial lower position), and thereby forcibly rotates and accelerates the product 12 (when supporting with a sharp end in the grip 3), i.e. thus reducing the time of forced orientation.

При ориентации остроконечных изделий 12 острым концом вниз прием, фиксация и взаимодействие захваченного изделия с толкателем 6 аналогично описанному. При этом острый конец изделия не удерживается ориентирующими элементами подпружиненного штока 10 и захвата 3 и попадает в лоток 21 через один из зауженных пазов щелевого ориентатора 14, выполненного в окне 8 для выгрузки изделий, тогда как утолщенная часть удерживается стенками другого зауженного паза щелевого ориентатора до полного разворота изделия 12 толкателем 6, т.е. осуществляется принудительная ориентированная выдача изделия острым концом вниз.When the pointed products 12 are oriented with the sharp end down, the reception, fixation and interaction of the captured product with the pusher 6 is similar to that described. In this case, the sharp end of the product is not held by the orienting elements of the spring-loaded rod 10 and grab 3 and enters the tray 21 through one of the narrowed grooves of the slot orientator 14, made in the window 8 for unloading products, while the thickened part is held by the walls of the other narrowed groove of the slot orientator to the full pivoting the product 12 with the pusher 6 forced oriented issue of the product is carried out with the sharp end down.

Процесс ориентации цилиндрических и т.п. стаканов дном вниз аналогичен изложенному для изделий с острым концом, с той лишь разницей, что удерживающий (в процессе разворота) ориентирующий элемент размещен внутри изделия 12 с возможностью разворота последнего при ориентации.The process of orientation of cylindrical, etc. cups bottom-down is similar to that described for products with a sharp end, with the only difference being that the retaining (in the process of turning) orienting element is placed inside the product 12 with the possibility of turning the latter during orientation.

В случае ориентированной поштучной выдачи из устройства легкоповреждаемых немагнитных конических изделий в каждой позиции перед окном 8 для выгрузки изделий установлен механизм принудительной ориентации, причем его толкатель 6, выполненный в виде шибера, перед подачей изделий 12 в приемник Д взводится стационарным кулачком 16, а после подачи из делия в приемник Д — выдает ориентированное изделие через выпускное окно 8 с заданной (кулачком 16) плавностью, обеспечивающей неповреждаемость изделия 12.In the case of oriented piecewise delivery of easily damaged non-magnetic conical products from the device in each position in front of the window 8 for unloading the products, a forced orientation mechanism is installed, and its pusher 6, made in the form of a gate, is cocked by a stationary cam 16 before feeding the products 12 to the receiver D, and after feeding from the division into the receiver D - gives an oriented product through the outlet window 8 with a given (cam 16) smoothness, ensuring the integrity of the product 12.

Во всех приведенных вариантах питания ориентированное изделие 12 через выход ной канал наклонного лотка 21 принудительно выдается в приемное гнездо 20 цепного конвейера 19, например, импульсом сЖатого воздуха, и цикл выдачи ориентированного изделия снова повторяется с каждым оборотом роторного питающего устройства.In all of the above power supply options, an oriented article 12 is forcibly delivered to the receiving slot 20 of the chain conveyor 19 through the output channel of the inclined tray 21, for example, with a compressed air pulse, and the cycle of issuing the oriented article is repeated again with each revolution of the rotary feeding device.

Claims

The invention relates to a machine tool industry, and more specifically to devices for automatically loading the working positions of technological machines with piece-oriented products from ferromagnetic and non-magnetic materials such as cone-shaped cylinders, self-clogging conical products, bodies of rotation with irreversible section over length, cylindrical glasses, and the like. as well as products with a lightly damaged surface. I The aim of the invention is to improve the reliability of the device by providing a forced orientation of the product. FIG. 1 shows a rotary feeding device, a longitudinal section; in fig. 2 - the same, when the orientation of the product with a sharp end up; in fig. 3 - the same, when the orientation of the product with a sharp end down; in fig. 4 - the same, when the orientation of the product type conical glasses bottom down; in fig. 5 - the same, with the orientation of products with easily damaging surface; in fig. 6 shows section A-A in FIG. 1. A rotary power supply device contains a drum 2 rigidly connected to the shaft 1, on the periphery of which the axially arranged working bodies are made in the form of grippers 3 controlled from sliders (not shown). The grippers 3 are installed with the possibility of reciprocating movement in the guide holes 4 of the drum 2. A vertical receiver D is made in each guide hole 4. The forced orientation mechanism 5 is equipped with a pusher 6. made, for example, in the form of a disk, which fits into an annular groove 7, performed on the perimeter of the drum 2 on its inner surface. In this case, the geometric axis of rotation of the disk is located in a vertical plane. On the side surface of the drum 2, exhaust ports 8 are provided for unloading products, the number of which corresponds to the number of working positions of the rotor. Above each gripper 3, coaxially mounted in guides 4 is a spring 10 spring 9 of the brush 10, at the end of which there is a centering nest 1 for the product 12, and the end surface of the grips 3 has an orienting element 13 made either as a socket or as a pin. Slot orientators 14 in the device are formed by grippers 3 and spring-loaded rods 10 in their extreme upper position. In order to dispense conical articles 12 from the device with a sharp end downward, the slot orientators 14 are provided in outlet ports 8 in vertical planes parallel to the geometric axis of the drum. For issuing conical products with a easily-damaging surface, such as soft materials, a forced orientation mechanism is installed in each window for unloading products 8 (perpendicular to the window for unloading products 8), the pusher 6 of which is made in the form of a gate connected by a rod 15 with a reciprocating drive in the form of a stationary cam 16 through which roller 17 rolls in. On the outer surface of the drum 2 a sprocket 18 of a chain conveyor 19 is rigidly attached to it, e jacks 20 which are arranged under the outlet channels sloped trays 21. Under drum 2 taken feeder 22, for example, socket 23 of the chain conveyor 24. The rotary feeder operates as follows. The product 12 from the feeder 22, for example, the nest 23 of the chain conveyor 24, when the drive shaft 1 rotates, is picked up by the gripper 3 and forcibly, in a known manner, is fed to the vertical receiver 1. made in the guide hole 4. The upper end of the product 12 enters the jack 11 of the spring-loaded stem 10 (for example, conical for pointed products) and centered along the axis of the receiver D. Thus, it is simultaneously gripped on both sides: on one side, gripper 3, and on the other, spring-loaded stem 10, i.e. the latter form a stencil, as it were, sliding along the axis of the product. Upon further joint upward movement with the product 12 clamped on both sides, the spring-loaded stem 10 opens a window 8 for unloading products, at this time the gripper 3 takes a position where its upper edge is slightly higher than the bottom of the window 8 for unloading products. As a result, the products 12 are accurately fixed in the receiver D against the outlet port 8 for unloading the products and overlaps the through side groove 7. With further rotation of the drum 2, the product 12 vertically fixed in the receiver D approaches the stationary mechanism of forced orientation 5, the plunger 6 of which, for example, a disc, interacts through the annular groove 7 with the product 12. In this case, if necessary, orienting the conical products 12 with the thickened end down, the sharp end of it (regardless of the initial orientation in the stencil - up or down) is held in slot II of the spring-loaded stem 10 or in slot 13 of the gripper 3, and the thickened end is not held and either collides with the gripper 3 into the outlet port 8 for unloading products, or forcibly unfolds in window 8 for unloading products by the pusher 6 with the support of the product 12 with the sharp end into the nest 13 of the gripper 3. In this case, the spring 10 moves with the action of the spring 9 (to its initial lower position), and thereby forcibly turns and accelerates the product 12 (with the sharp end of the gripper 3) i.e. thus, the forced orientation time is reduced. When the pointed products 12 are oriented with a sharp end downward, the receiving, fixing and interaction of the captured product 12 with the pusher 6 is similar to that described. At the same time, the sharp end of the product is not held by the orienting elements of the spring-loaded brush 10 and the gripper 3 and enters the tray 21 through one of the narrowed grooves of the slotted orientator 14 made in the window 8 for unloading products, while the thickened part is held by the walls of the other narrowed slot of the slotted orientator to full turning the product 12 by the pusher 6, i.e. A forced oriented dispensing of the product with a pointed end is carried out. The process of orientation of cylindrical, etc. The glasses are bottom-down similar to those described for products with a sharp end, with the only difference being that the retaining (during the turn) orienting element 13 is placed inside the product 12 with the possibility of reversing the latter during orientation. In the case of oriented piece delivery of a device of easily-damaging non-magnetic conical products, a forced orientation mechanism is installed at each position in front of window 8 for unloading products, and its pusher 6, made as a chibber, is driven by a stationary cam 16 before supplying products 12 to receiver D, and after feeding products to the receiver D - delivers an oriented product through the outlet port 8 with a predetermined (cam 16) smoothness that ensures the damage of the product 12. In all of the above power options, The oriented product 12 is forced through the exit channel of the inclined chute 21 to the receiving port 20 of the chain conveyor 19, for example, with a compressed air pulse, and the delivery cycle of the oriented product repeats again with each turn of the rotary feeder. Claim 1. Rotary feeding device comprising a drum mounted on the rotor shaft, on the periphery of which are mounted with the possibility of reciprocating movement in the vertical direction of the grippers and a mechanism for the forced orientation of products, with guide holes and openings for unloading products made in the drum, characterized in that, in order to increase the reliability of the device, it is provided with drum-mounted grippers mounted in a drum above the windows for unloading products reed rods, in the ends of which there is a centering nest under the product, and on the inner surface of the drum an annular groove is made perpendicular to the axes of the guide holes, while the mechanism of forced orientation of the products is installed in the specified annular groove.
