Abstract

1495606 Discharging articles through shoots KOMBINAT UMFORMTECHNIK HERBERT WARNKE ERFURT VEB 6 March 1975 [8 March 1974] 9369/75 Heading B8S A device for feeding headed workpiece blanks 21 to a processing station comprises a pair of elongate parallel bars 1, 2 disposed one above the other and defining a guide gap (3) therebetween, Fig. 2 (not shown), the bars 1, 2 being inclined longitudinally at an angle to the horizontal so that blanks in the gap (3) are fed therealong by gravity, the bars 1, 2 also being inclined transversely at an angle (5) to the horizontal, Fig. 5 (not shown) in order to receive the blanks by their unheaded portions from an orientating station of the device. The said station comprises a rotatable cone or rotatable truncated cone 9, part of whose surface envelope lies in the same plane as the bottom surface of the guide gap (3). The cone 9 rotates along with a rotor 10 which is operative to raise the blanks from a bin 12 so that the blanks drop on to the surface of the cone 9, a catch plate 13 being provided to enlarge the catching surface for the blanks. In a second embodiment of feeding device, Figs. 6-8 (not shown), a catch guide plate (20) is provided at the blank orientating station, as an alternative to the cone 9.

Description

7 - вид D фиг. 6; на фиг. 8 - сечение Е-Е фиг. 7.7 is a view D of FIG. 6; in fig. 8 is a cross-section E-E of FIG. 7

Устройство состоит из бункера 1, ротора 2 с лопаст ми 3, наклонного отводного лотка 4, образованного двум направл ющими 5 и 6, образующими паз 7 дл перемещени заготовок 8. Отводной лоток 4 установлен с разворотом вокруг своей оси и относительно вертикальной плоскости. В месте ввода заготовок в паз отводного лотка на одной оси с ротором 2 установлен вращающийс усеченный конус 9, который облегчает ввод заготовок и предотвращает их заклинивание . В верхней части нижней направл ющей отводного лотка на оси 10 установлена приемна пластина 11, прилегающа к усеченному конусу 9. Напротив наза 7 с конусом 9 контактирует захватна пластина 12. Приемна нластина 11, конус 9 и захватна пластина 12 образуют приемник заготовок. Поверхность 13 верхней направл ющей 5 смещена относительно поверхности 14 нижней направл ющей 6. Поверхность 14 установлена под острым или пр мым углом к пазу 7 отводного лотка . Благодар такому расположению направл ющих поверхностей заготовки могут не только скользить, но и катитьс . На торцах направл ющих установлены планки 15 и 16.The device consists of a hopper 1, a rotor 2 with blades 3, an inclined diversion tray 4 formed by two guides 5 and 6, forming a groove 7 for moving workpieces 8. The bypass tray 4 is installed with a turn around its axis and relative to a vertical plane. A rotating truncated cone 9 is installed at the insertion point of the blanks into the groove of the bypass tray on the same axis as the rotor 2, which facilitates insertion of the blanks and prevents them from jamming. In the upper part of the lower guide bypass tray, an receiving plate 11 is mounted on the axis 10 adjacent to the truncated cone 9. Opposite to the nas 7, the gripping plate 12 contacts the cone 9. The receiving plate 11, the cone 9 and the gripping plate 12 form the receiver of the blanks. The surface 13 of the upper guide 5 is offset from the surface 14 of the lower guide 6. The surface 14 is set at an acute or right angle to the slot 7 of the bypass tray. Due to this arrangement, the guiding surfaces of the workpiece can not only slide, but also roll. The ends of the rails are fitted with strips 15 and 16.

Устройство работает следующим образом .The device works as follows.

Заготовки, наход щиес в бункере, захватываютс лопаст ми 3 ротора 2 и сбрасываютс на захватную пластину 12 и усеченный конус 9, с которого но приемной нластине 11 ввод тс в паз 7 наклонного отводного лотка 4. Введенные в наз заготовки скольз т или кат тс к позиции обработки , проход через сортировочные ролики 17. Окончательно сориентированные заготовки перемещаютс по пазу отводного лотка, поддержива сь сверху планкой 18. Планка 15 преп тствует тому, чтобы невведенные в паз заготовки на головках введенных заготовок попадали к сортировочным роликам. Кроме того, неправильно введенные заготовки при помощи верхней планки 15 сбрасываютс в бункер 1. При транспортировке заготовок нижн планка 16 служит дл дополнительного подпирани головок заготовок.The blanks located in the bunker are captured by the blades 3 of the rotor 2 and dropped onto the gripping plate 12 and the truncated cone 9, from which the receiving plate 11 is inserted into the groove 7 of the inclined diversion tray 4. processing positions, passage through the sorting rollers 17. Finally, the oriented blanks are moved along the groove of the bypass tray, supported by the bar 18 from above. The bar 15 prevents the blanks not inserted into the groove on the heads of the inserted blanks from falling to the screen th rollers. In addition, improperly inserted blanks are dropped into the hopper 1 with the help of the upper bar 15. When transporting the blanks, the lower bar 16 serves to further support the heads of the blanks.

При подаче коротких заготовок 8, не склонных к заклиниванию в месте ввода, приемник заготовок выполн етс в видеWhen feeding short blanks 8 that are not prone to jamming at the insertion point, the receiver of blanks is made in the form of

захватно-приемной пластины 19, установленной на оси 20 в верхней части наклонного отводного лотка и расположенной в плоскости его нижней направл ющей 6, Посредством поворота пластины 19 паз 7 в дополнение к предварительной регулировке с помощью верхней направл ющей 5 увеличиваетс или уменьшаетс в зависимости от размеров заготовки.pick-up plate 19 mounted on axis 20 in the upper part of the inclined bypass tray and located in the plane of its lower guide 6. By rotating plate 19, the groove 7 in addition to being pre-adjusted with the upper guide 5 blanks.
