DE2019211B2 - Control device for a distribution conveyor system, in particular a log sorting system - Google Patents

Description

The invention relates to a control device anch the Preamble of claim 1.

Such a control device is known from Finnish patent 37,227. The rods of the well-known Devices are transverse to their direction of travel and parallel to one another and to the perpendicular axis of rotation the control device arranged along a circular line, while the annular groove-shaped Guides are arranged one above the other in the axial direction on a cylinder jacket, Each guide is assigned a selector magnet with an ejection device.

The invention is based on the object of a still Simpler and less space-consuming, reliably working mechanical-electrical control device to create that, thanks to its uncomplicated construction, is significantly cheaper to manufacture comes to a standstill than the currently common electrical or mechanical-electrical control devices.

The invention solves this problem by a tax Ί er device with the characterizing features of claim 1.

The following is an embodiment of the inventive Control unit described on the basis of the drawing:

1 shows a partial view of an embodiment of the control device according to the invention from FIG Viewed from the wheel side;

Fig. 2 shows a section along the line I-I in Fig. 1;

Fig. 3 shows a section along the line H-II in Fig. 1;

Fig. 4 shows a section along the line III-II1 in Fig. 2;

FIG. 5 shows a section along the line IV-IV: n in FIG. 2.

The control unit consists of the following main structural parts:

- a frame 1, which is fixedly mounted in the vertical position and a row on one side

r> centric groove-shaped guides 5 and one

Has guide device 6;

- A wheel 2, the axis of which is mounted in the center of the guides 5 and which rotates synchronously with the conveyor device, which of this

is controlled in the control unit. The wheel is radial

running round rods 8 occupied, which in turn each carry a runner 9. This is axially movable on the rod and in the groove-shaped guides;

i) '- electrical scanning devices in the form of limit switches 3, which are attached to the groove-shaped guides 5 sit that they are moved by the runners 9 in the guides 5 as they slide past be touched. The brackets 11 of the

in limit switches are attached to the frame in such a way that

they are each brought into the position required for operation relative to the groove-shaped guide 5 can be;

- An adjusting device 4, which on the opposite ■ i "i set side of the groove-shaped guides on

upper part of the frame 1 is arranged on a vertical radius, where the runner with Using the adjusting member 14 are released. The runners slide along the bars and become ■> ii at a desired point on the rod

Using the adjusting members 15 stopped. Each individual groove-shaped track is its own Adjusting member 15 assigned. The adjustment glicder are operated with the help of electromagnets.

Way of working

When the conveyor is idling, the control unit has no control function. The wheel 2 rotates synchronously to the movements of the conveyor, and

mi the runners 9 wander, from the guiding device 6, on the outermost lane, but without being released by the setting device 4 or its setting member 14 to become.

Will the conveyor come up with an item attached to

n-, a certain point is to be transported, loaded, so the point corresponding to this unloading point is set on the groove-shaped path with the aid of the adjusting member locked. Next, the adjusting member 14 is opened,

so that the runner 9 marking the object to be transported slides on the rod 8 to the single-step member 15 and then changes over to the groove-shaped path assigned to it, which in turn has a limit switch 3 at a certain point, when it is touched by the runner z. B. the handover is triggered the transported object from one conveyor to the other. Thereafter, the runner reaches the guide apparatus 6 and is ready for new control tasks. the device 17 is' ⁿ the correction of incorrect settings.

In its simplest form, the control device must have at least the same number of groove-shaped guides 7 as the conveyor device has stations over its entire length. Furthermore, the number of ι ~> Runner 9 must at least match the number of the conveyor while transporting items. In order to reduce the size of the control device, one (or more) additional rotor (s) 10 can be fitted to each rod. - '<> There are then two additional groove-shaped guides 7 on the frame and one additional! Limit switch 12 on the limit switch brackets 11 required. With the aid of the setting member 16, the surplus rotor 10 is directed to one of the two groove-shaped guides 7, so that the switching possibilities of the control device of the conveyor device double.

The advantage of this construction z. B. compared to the known control device described above consists in the simple and much cheaper construction as well as in the small space requirement. Continues to exist in the device according to the invention also the possibility of having two mechanisms on one and the same To arrange axis.

The monocoque links are provided with a cam, which the runner strikes and thereby returns the adjusting member to its neutral starting position. The adjusting member 14 is best provided with a spring 19 which the adjusting member normally holds in effective position. The setting device 14 is only used to enable a runner with the aid of a Electromagnet temporarily open.

The drive devices of the Einstcllglieder iS be advantageously both sides r "arranged r adjuster 13, which is not shown for the sake ier clarity in the drawings in detail for the same reason were also the holders 11, the limit switch partially omitted...
