Description

Изобретение относится к транспортным устройствам, а именно к устройствам для поворота в горизонтальной плоскости изделий, движущихся по конвейеру.The invention relates to transport devices, and in particular to devices for turning in the horizontal plane of products moving along the conveyor.

Известно поворотное устройство, содержащее стол и механизм подъема и поворо- 5 та стола, выполненный в виде неподвижно связанного со столом двухзаходного полого винта, с размещенной внутри него стойкой с поводком. Конец стойки, снабженный роликом, взаимодействует с направляю- ₁₀щей, имеющей горизонтальный и наклонный участки, причем на последнем происходит подъем и одновременно поворот стола [1].A rotary device is known comprising a table and a table lifting and turning mechanism 5 made in the form of a two-way hollow screw fixedly connected to the table, with a stand with a lead placed inside it. The end of the rack, equipped with a roller, interacts with the guide ₁₀ , which has horizontal and inclined sections, and at the last there is a rise and at the same time table rotation [1].

Однако в этом устройстве поворот стола осуществляется только одновременно с его 15 подъемом или опусканием, при этом при подъеме стол поворачивается на заданный угол, а при опускании возвращается в исходное положение, т. е. уровень стола в исходном положении разный. Вследствие ₂₀этого такое устройство не может быть использовано для поворота груза на конвейере.However, in this device, the table is rotated only at the same time as it is raised or lowered, while the table is rotated by a predetermined angle when lifting, and when lowering, it returns to its original position, i.e. the table level in the initial position is different. Because of this, ₂₀ such a device cannot be used to turn cargo on a conveyor.

Наиболее близким к предлагаемому по технической сущности и достигаемым ре2 зультатам является устройство поворота изделий на конвейере, включающее стол, механизм его поворота с упором для взаимодействия с толкателем и механизм подъема стола в виде стойки с роликом на конце для взаимодействия с направляющей [2].The closest to the proposed technical essence and the achieved results are a device for turning products on a conveyor, including a table, a mechanism for turning it with a stop for interaction with a pusher, and a table lifting mechanism in the form of a rack with a roller at the end for interaction with a guide [2].

Однако при повороте последовательного ряда изделий в одну и ту же сторону, что требуется при ориентировочной подаче изделий, после каждого поворота стол необходимо вхолостую повернуть в исходное положение. Это снижает производительность устройства.However, when turning a sequential row of products in the same direction, which is required for an approximate supply of products, after each rotation, the table must be idly rotated to its original position. This reduces the performance of the device.

Кроме этого, для устройства характерна недостаточная точность поворота изделий на заданный угол из-за отсутствия жесткой фиксации стола в момент окончания его поворота, когда упор диска выходит из зацепления с вилкой, стол под действием инерционных сил может еще повернуться на некоторый угол.In addition, the device is characterized by insufficient accuracy of rotation of the products at a given angle due to the lack of rigid fixation of the table at the end of its rotation, when the emphasis of the disk is out of engagement with the fork, the table under the influence of inertial forces can still rotate by some angle.

Целью изобретения является повышение производительности устройства, обеспечивающего ориентированный поворот изделий.The aim of the invention is to increase the performance of the device, providing an oriented rotation of the products.

Указанная цель достигается тем, что устройство снабжено дополнительными кулачками, размещенными вокруг стойки с одинаковым шагом, а направляющая выполнена в виде ползуна, на котором установлен толкатель, причем последний выполнен с пазом на конце и имеет прижим.This goal is achieved by the fact that the device is equipped with additional cams placed around the rack with the same pitch, and the guide is made in the form of a slider on which the pusher is mounted, the latter being made with a groove at the end and has a clamp.

Кроме того, прижим выполнен в виде подпружиненного рычага, установленного с возможностью взаимодействия с кулачками и толкателем.In addition, the clamp is made in the form of a spring-loaded lever mounted with the possibility of interaction with the cams and pusher.

Устройство поворота изделий на конвейере, в частности на рольганге, содержит раму 1, на которой закреплены направляющие ролики 2, вращающиеся на осях 3. На роликах 2 с возможностью возвратно-поступательного перемещения в горизонтальной плоскости установлена направляющая 4, имеющая горизонтальные 5 и наклонный 6 участки. Направляющая 4 связана с реверсивным приводом, в частности пневмоцилиндром 7 с муфтой 8. Стол 9, выполненный в виде крестовины, решетки или гребенки, неподвижно закреплен на основании 10, в виде стакана. Основание 10 опирается на узел 11 крепления через стойку 12, выполненную в виде плунжера, в верхней части которого установлена опора 13 с шариком 14, взаимодействующим с опорой 15 основания стола, а в нижней части закреплен на оси 16 ролик 17, опирающий на направляющую 4.The device for turning products on a conveyor, in particular on a roller table, comprises a frame 1 on which guide rollers 2 are mounted, rotatable on the axles 3. On the rollers 2, a guide 4 having horizontal 5 and inclined 6 sections is mounted on a horizontal plane . The guide 4 is connected with a reversible drive, in particular a pneumatic cylinder 7 with a clutch 8. Table 9, made in the form of a cross, a grill or comb, is fixedly mounted on the base 10, in the form of a glass. The base 10 is supported by the attachment unit 11 through a stand 12, made in the form of a plunger, in the upper part of which there is a support 13 with a ball 14 interacting with the support 15 of the table base, and a roller 17 fixed to the guide 4 is fixed on the axis 16.

На направляющей 4 закреплена ось 18, на которой шарнирно установлен толкатель 19 с пазом 20 на конце, а на стакане концентрично его оси с равным шагом установлены кулачки 21 со втулками 22. Угол между кулачками 21 соответствует углу поворота стола, т. е. их может быть три, четыре и т. д. В приведенном примере их четыре, что соответствует углу поворота 90°. На раме 1 закреплен прижим 23, содержащий рычаг 24, установленный на оси 25, подпружиненный пружиной 26 кручения. Рычаг 24 имеет поджимную 27 и упорную 28 кромки.An axis 18 is fixed on the guide 4, on which the pusher 19 is pivotally mounted with a groove 20 at the end, and cams 21 with bushings 22 are mounted concentrically on its axis with an equal pitch. The angle between the cams 21 corresponds to the angle of rotation of the table, i.e., they can be three, four, etc. In the given example there are four of them, which corresponds to a rotation angle of 90 °. A clamp 23 is fixed on the frame 1, comprising a lever 24 mounted on an axis 25, spring loaded with a torsion spring 26. The lever 24 has a pinch 27 and a persistent 28 edge.

Устройство поворота изделий на конвейере работает следующим образом.The device turning products on the conveyor operates as follows.

Изделие 29 движется по рольгангу 30. При прохождении изделия над столом 9 срабатывает датчик (не показан), включающий привод 7, который перемещает направляющую 4 влево по чертежу. При прохождении наклонного участка 6 направляющей под роликом 17 стойки 12 вместе со столом 9 поднимаются, приподнимая изделие 29 над роликами рольганга 30.The product 29 moves along the roller table 30. When the product passes over the table 9, a sensor (not shown) is activated, which includes a drive 7, which moves the guide 4 to the left according to the drawing. When passing the inclined portion 6 of the guide under the roller 17, the posts 12 together with the table 9 rise, lifting the product 29 above the rollers of the roller table 30.

При дальнейшем движении направляющей 4 в том же направлении ролик 17 взаимодействует с ее горизонтальным участком, при этом уровень стола не меняется. В этот момент толкатель 19, установленный на направляющей, своим пазом 20 захватывает втулку (упор) 22 стакана 10 и поворачивает последний вместе со столом 9 на определенный угол. При этом подпружиненный рычаг 24 своей поджимной кромкой 27 постоянно прижимает толкатель 19 к кулачку 21. В момент окончания поворота на заданный угол, который соответствует углу между смежными кулачками 21, на упорную кромку 28 рычага 24 наезжает следующий кулачок 21, что исключает инерционный пробег стакана 10 со столом 9, т. е. повышает точность ориентации изделия.With further movement of the guide 4 in the same direction, the roller 17 interacts with its horizontal section, while the table level does not change. At this moment, the pusher 19, mounted on the guide, grabs the sleeve (stop) 22 of the cup 10 with its groove 20 and rotates the latter together with the table 9 by a certain angle. In this case, the spring-loaded lever 24 with its clamping edge 27 constantly presses the pusher 19 to the cam 21. At the end of the rotation by a predetermined angle, which corresponds to the angle between adjacent cams 21, the next cam 21 runs onto the stop edge 28 of the lever 24, which eliminates the inertial mileage of the cup 10 with table 9, i.e., it increases the accuracy of product orientation.

В это время датчик (не показан) дает команду на реверс привода 7. Направляющая 4 с толкателем 19 перемещается в обратную сторону, толкатель 19 отжимает рычаг 24 и проходит мимо следующего кулачка 21, а стойка 12, обкатывая роликом 17 наклонный участок 6 направляющей, опускает стол 9 ниже уровня роликов рольганга 30, при этом изделие 29 остается на рольганге.At this time, a sensor (not shown) gives a command to reverse the drive 7. The guide 4 with the pusher 19 moves in the opposite direction, the pusher 19 depresses the lever 24 and passes by the next cam 21, and the stand 12, rolling the inclined section 6 of the guide by rolling the roller 17, lowers table 9 is below the level of the rollers of the roller table 30, while the product 29 remains on the roller table.

Устройство может иметь другое средство для поджима рычага 20 к втулке 22, например пружину, а также другое средство для фиксации втулки 22 в конце ее поворота на заданный угол, например неподвижно установленный на раме 1 упор. Однако объединение этих средств в один прижим упрощает конструкцию устройства.The device may have other means for pressing the lever 20 to the sleeve 22, for example, a spring, as well as other means for fixing the sleeve 22 at the end of its rotation by a predetermined angle, for example, a stop fixed to the frame 1. However, combining these tools in one clip simplifies the design of the device.

Claims

The invention relates to transport devices, namely, devices for horizontal rotation of articles moving along a conveyor. A pivoting device is known, comprising a table and a table lifting and rotating mechanism, made in the form of a double-threaded hollow screw fixedly connected to the table, with a stand with a lead placed inside it. The end of the stand, provided with a roller, interacts with a guide having horizontal and inclined sections, the table lifting and turning simultaneously takes place at the same time. However, the table is rotated only at the same time as it is raised or lowered, while turning the table at a given angle, and when lowering returns to its original position, i.e. the level of the table in the initial position is different. As a consequence, such a device cannot be used to rotate a load on a conveyor. The closest to the proposed technical essence and the achieved results is a device for turning articles on a conveyor, including a table, a mechanism for turning it with an emphasis for interacting with the pusher, and a mechanism for lifting the table in the form of a stand with a roller at the end for interacting with guide 2. However turning a consistent series of products in. one and the same side, which is required for the approximate supply of products, after each turn, the table must be idled to turn to its original position. This reduces the performance of the device. In addition, the device is characterized by insufficient accuracy of turning the articles to a predetermined angle due to the absence of rigid fixation of the table at the time of the end of its rotation, when the disk stop comes out of engagement with the fork, the table can still turn through some angle by the action of inertial forces. The aim of the invention is to increase the productivity of the device, providing oriented rotation of products. This goal is achieved by the fact that the device is equipped with additional cams placed around the stoics with the same pitch, and the guide is made in the form of a slider on which the pusher is mounted, the latter being made with a slot at the end and having a pressure. In addition, the clamp is made in the form of a spring-loaded lever, installed with the ability to interact with the cams and the pusher.

A device for rotating articles on a conveyor, in particular on a roller table, comprises a frame 1 on which guide rollers 2 are fixed, rotating on axes 3. On rollers 2, a guide 4 is installed with a possibility of reciprocating movement in a horizontal plane 5 and 6 sloping plots. The guide 4 is connected with a reversing drive, in particular a pneumatic cylinder 7 with a coupling 8. A table 9, made in the form of a cross, grid or comb, is fixedly mounted on the base 10, in the form of a glass. The base 10 rests on the fastening assembly 11 through a post 12, made in the form of a plunger, in the upper part of which a support 13 is installed with a ball 14 cooperating with the support 15 of the table base, and in the lower part a roller 17 is supported on the axis 16 Axis 18 is fixed on guide 4, on which pusher 19 with groove 20 is pivotally mounted at the end, and cams 21 with bushings 22 are mounted concentric to its axis with equal pitch. Cams 21 with bushings 22. The angle between cams 21 corresponds to the angle of rotation of the table, i.e. there may be three, four, etc. In when In the given example, there are four of them, which corresponds to a rotation angle of 90 °. On frame 1, a clamp 23 is fixed, comprising a lever 24 mounted on an axis 25, spring-loaded with a torsion spring 26. The lever 24 has a gland 27 and a thrust 28 edge. The device rotates the products on the conveyor works as follows. The product 29 moves along the roller conveyor 30. When the product passes over the table 9, a sensor (not shown) is triggered, including a drive 7, which moves the guide 4 to the left in the drawing. When the inclined section 6 of the guide under the roller 17 of the rack 12 together with the table 9 rises, the product 29 rises above the rollers of the roller table 30. With the further movement of the guide 4 in the same direction, the roller 17 interacts with its horizontal section, while the level of the table does not change is. At this moment, the pusher 19 mounted on the guide, with its groove 20, grips the sleeve (abutment) 22 of the cup 10 and turns the latter together with the table 9 by a certain angle. At the same time, the spring-loaded lever 24 constantly presses the pusher 19 against the cam 21 with its pressing edge 27. At the end of the turn, the next cam 21 hits the thrust edge 28 of the lever 24 at the predetermined angle that corresponds to the angle between adjacent cams 21 10 with a table of 9, i.e., increases the accuracy of orientation of the product. At this time, the sensor (not shown) gives the command to reverse the drive 7. The guide 4 with the pusher 19 moves in the opposite direction, the pusher 19 pushes the lever 24 and passes the next cam 21, and the post 12 rolls around the inclined section 6 with the roller 17 , lowers the table 9 below the level of the rollers of the roller table 30, while the product 29 remains on the roller table. The device may have other means for pressing the lever 20 against the sleeve 22, for example a spring, as well as other means for fixing the sleeve 22 at the end of its rotation at a predetermined angle, for example a stop fixed on the frame 1. However, combining these tools into one clamp simplifies the design of the device. Claim 1.
