DE2627017A1 - Warp beam transporter - using position switches to give automatic horizontal control while suspended from crane hooks - Google Patents

Abstract

While wound warp beams, together with their associated loom harnesses, are being transported from the warping station to the loom, there is an automatic horizontal control in one or two planes, laterally and longitudinally, while suspended from one to more crane hooks. This is effected by positional switches and transmission carriers to ensure that the crane's lifting point always remains over the centre of gravity of the total load, with its various attachments. The system ensures that the warp beam and loom harness are carried horizontally and accurately, without requiring large access areas for the transporter.

Description

above-floor warp beam and harness loading device with automatic

matic horizontal control in 2 levels for textile companies.

Have the transport equipment primarily required in a weaving mill corresponding to the warp beams and harnesses (shafts and lamella packs) dimensions and weights are achieved that are practically impossible to achieve manually are more manageable.

So already have transport equipment with tractors or self-propelled found its way into weaving preparation / weaving, but problems still remain when feeding the looms because of the extremely narrow warp beam aisles and the difficulty of getting into these aisles and warp beams on the loom and to be able to insert dishes.

The aircraft that have been used up to now require sufficient Aisle widths and thus an expensive and economical space requirement.

The idea is therefore obvious, as in other branches of industry It has long been known to use above-ground means of transport. Now, however, occur when hanging The transport of warp beams and harnesses presents considerable difficulties. they are given by the fact that withdrawn chains (with one known exception, namely patent application 2403746.5 "transport and insertion device for warp beams and harnesses ") have not yet been able to be inserted at all However, registration has the disadvantage that the device in the hanging transport state is very long and therefore requires a considerable building height.

In addition, no solution is shown there either, as is the case all the time changing and, above all, shifted weights in 2 levels so that the warp beams and harness remain permanently in a horizontal position.

To make matters worse, that is inevitable when loading the loom by removing individual parts (warp beams, individual Shafts, lamellas etc.) the center of gravity shifts continuously and the device continuously comes out of the horizontal position, as far as it was before - time-consuming and awkward - was balanced.

The constant maintenance of the horizontal position is because of the indented chain is vital, otherwise confusion and Damage to the individual warp threads would inevitably occur. Furthermore precise insertion into the bearing points of the weaving machine can only be carried out smoothly "take place in a balanced, horizontal alignment. It is therefore according to the invention a simple device has been developed, which an automatic center of gravity control and thus warp beams, crockery and slats always in the horizontal transverse and holds its length, even during the loading and unloading process.

Fig. 1 shows the side view of the device (section a + b) and a Partial view of the loom.

Fig. 2 shows the rear view of the device loaded with an in The width of the warp beam is not fully warped and is offset to the side.

Fig. 3 shows the top view of the device.

Fig. 4 shows a schematic diagram of the automatic control for the Horizontal transverse adjustment (and thus shifting the center of gravity) of the device.

Fig. 5 shows a basic sketch like Fig. 4, but for the horizontal longitudinal adjustment the device.

According to the invention, the device consists of the longitudinal members 1, the Vertical beams 2 and the cross beams 3.

The warp beam 4 is supported by the displaceable support arm 5 the lower side member 1 from while the moment is absorbed by the tube 6. Take the cross member 3 the shaft package 7 and the lamella package d on. An additional frame is attached between the middle cross members 3, which is also connected to the upper side members 1. The frame consists of four Rails 9 and has two metal sheets 10 as a lateral boundary. Between the rails 9 four rollers 11, which are attached to a carriage 12, run. The ways 12 becomes formed from two longitudinal spars 13 and two cross connections 14. In the middle of Carriage 12 are two webs 15 angeoranet, in which a one-armed lever 16 can be rotated is stored and at the upper end of the crane hook 17 of a not shown Attacks the hoist.

Approximately in the middle of the lever 16, the piston rod 18 engages twice acting cylinder 19, which is also mounted between the webs 15. One Nut 20 is rotatably attached to the carriage 12, a threaded spindle goes through it 21, which is mounted on both sides on the metal sheets 10 of the frame.

To move the carriage 12 in the longitudinal direction, the spindle 21 driven by a gear motor 22, for example.

According to the invention and according to the selected Ausführungsr example the balance of the center of gravity in the transverse direction is made by a hydraulic cylinder, which acts directly on the lever 16, achieved while in the longitudinal direction of the compensation by means of a movable carriage - e.g. via a gear motor.

An example is used to explain the principle of the control Circuit diagram shown in Fig. 4. Two slightly curved mercury tubes 24 + 32 each have three contacts clocks 25, 26 and 27. The mercury tube 24 is accurate arranged horizontally in the transverse direction. Tilts when loading and unloading in the crane 17 hanging device, forward or backward, in the transverse direction, so connects the mercury either contacts 25 + 26 or 25 + 27.

ie the circuit diagram (Fig. 4) shows, as long as the contact Destenen remains, the coil 2d or the coil 29 of a 3-counter valve 30 is energized and the control valve 31 shifted either left or right. This of course; result that the pressure oil a pump either in one or the other cylinder chamber of the double-acting Cylinder 19 is pressed. The piston movement caused by the lower diameter Via the piston rod 1 of the lever 16 as long to one side or the other moved, ois the crane application point 23 is again exactly above the total center of gravity. This means that the device is level again and the mercury is in the tube 24 is back in the middle.

The control spool goes through the power interruption caused by this 31 back to its middle position, whereby the inflow and outflow & 3 of the DrucKöls, to or from the hydraulic cylinder 19 is closed.

If, on the other hand, there is a shift in the center of gravity in the longitudinal direction a, (Fig. j) so the mercury tube 32 enters through the longitudinal inclination of the device to one side or the other in action. Thus the contacts 33, 34 or 33, 35 scanned over the mercury. So that one of the coils 37 or 3b of the reversing contactor 36 energized and either the corresponding contacts for the Left or the counter rotation of the motor 22 connected. The motor 22 drives the lead screw 21 and thus moves the carriage 12 with the crane application point 23 until this has again reached the overall center of gravity and the device is in a horizontal position, with the mercury of the tube 32 also in the Middle lies.

Of course, a different one can also be used instead of a mercury tube Switching element can be used for horizontal display and control.

Also means to prevent overdrive (for decelerating and Steaming etc.) can be provided.

As can be seen from Fig. 2, the center of gravity can be in the longitudinal direction, because of the one-sided storage of a not fully attached warp beam, already at Pick up from the middle. Already during loading then takes place, as already described, the compensation takes place automatically in the transverse and longitudinal directions. Is the loaded device once in the balance, the power supply is interrupted and the transport to the weaving machine in question can be carried out by crane system; a possible slight commuting during transport has no effect on the control.

Once you have reached the loom, you can then use a plug or a switch the power connection is established and the automatic control when inserting the retracted chain will be effective again.
