Definitions

  • the invention relates to a device for low-noise buffering and transverse transport of rollable, elongated rolling stock according to the preamble of the main claim.
  • a generic device is known from DE-OS 24 59 229. With this device, tubes can be moved transversely along a horizontal production line, a transport chain lying parallel to the production line having a plurality of drivers arranged at intervals causing the transverse transport.
  • the drivers have a driver arm which is rotatably attached to the transport chain with its inner end and which is held in the gripping position by means of a spring.
  • the spring force is adapted to the weight and the friction of the pipes to be transported so that the driving arm is turned so far back when it hits a pipe group that it runs past the pipes while canceling its driving action.
  • a disadvantage of this proposal is the precise adjustment of the spring force to a specific pipe weight and to the friction resulting from the surface conditions of the pipe, web surface and contact roller. This means that with this device only uniform pipes can be transported in terms of size and weight and with regard to the surface condition. Any change to one of the parameters results in a new spring force, and in some circumstances a different spring with a different spring characteristic may be required.
  • the object of the invention is to provide a device which allows a precisely parallel transverse transport of rollable rolling stock of different sizes and with different surface conditions in a simple and inexpensive manner and also a low-noise and surface-friendly buffering of the rolling stock.
  • the transverse transport of the rolling stock takes place in the device according to the invention in such a way that the transport path has a discharge grate formed from support stands and supports, inclined in the direction of transport, and the rollable rolling stock rolls downwards along this grating.
  • this type of transport would correspond to a non-guided transverse transport with the disadvantage that the rollable rolling stock can skew during rolling on the one hand and on the other hand in the case of a rolling stock made of steel with deafening noise against the stop or against the would hit the foremost layer of the already stowed goods. With such an impact, the surface of the rolling stock to be collected can be damaged in places.
  • the device according to the invention has a plurality of pivotable stop elements which are arranged at intervals on an endlessly running, driven transport chain, which is guided and driven via deflection rollers attached to the ends of the drain grate.
  • the stop element is designed as a solid thumb with an essentially square cross section and has a pivot axis which is offset from the center of gravity. Due to the leverage of differently distributed masses, the thumb stands upright as soon as it is in the area of the upper strand of the transport chain, this uprighting not being dependent on the size and weight of the rolling stock to be transported.
  • the thumb has two attachment points to determine the degree of upright position and to maintain the horizontal position in the area of the stowed goods and in the area of the lower run of the transport chain.
  • the connection of the thumb to the transport chain is established via a bearing block, which consists in a simple manner of web plates welded to the outer link plates, each with a bearing bush.
  • An axle pin is supported in the bearing bushes, with which the thumb is attached via a pin.
  • the stop point for determining the degree of the upright position of the thumb can be designed as a recess which is arranged at the end which is opposite the end of the thumb bearing the contact point and extends from the long side, which forms the underside in the region of the upper strand, to at least extends to the center of the width and over the entire thickness.
  • the other attachment point is designed in a similar manner to maintain the horizontal position.
  • This also has a recess which is arranged in the region of the center of gravity of the thumb, in which a pin arranged on the bearing block engages.
  • this pin prevents the thumb from folding down as soon as it is in the area of the lower run of the transport chain and at the same time prevents the thumb from lifting up on the other side when it is pressed down in the area of the upper run by the rolling stock that has already been jammed.
  • the thumb is erected in such a way that the contact roller protruding over the drain grate prevents the goods from rolling off.
  • the rolling stock to be rolled onto the drain grate is caught by the thumb raised.
  • the impact can be damped in terms of noise by covering the contact roller made of steel or another metal with a damping material, for example plastic.
  • the degree of thumb upright is affected by several opposing parameters.
  • the contact roller should protrude as far as possible above the path level of the drain grate in order to securely catch even the largest rolling stock in diameter, on the other hand, the inclined position of the thumb should be stable, i.e.
  • the angle must not be too large, since in the case of an angle of 90 degrees the leverage of the unevenly distributed masses becomes zero and the length of the thumb is also limited for reasons of space.
  • An angle range of 30 degrees to 45 degrees is usually selected.
  • the angle for the upright position of the thumb must also not be too small, since there is then the possibility that the thumb is pressed under the plane of the web by the rolling stock rolling on.
  • the condition must be met that for the rolling stock with the largest diameter to be transported, the extension of the connecting line from the center of the rolling stock to the point of contact of the rolling stock on the contact roller runs above the pivot point of the pivot axis with the thumb upright.
  • the endlessly running transport chain which moves in the transport direction by means of a driven deflection roller in the upper run, drags the thumbs arranged on it so that the rolling stock is transported transversely.
  • the thumb gets into the area of the stop or the material that has already been jammed, it is gradually pivoted against the force of gravity and this pivoting movement is regulated in such a way that the noise of the rolling material striking is negligibly small.
  • damage to the surface is avoided by the braked stop.
  • the fixed stop is covered with a plastic covering.
  • each transport chain having several stop elements which consist of two parallel thumbs or a pair of thumbs and the transport chain is located in the space between the pair of thumbs.
  • the synchronization of the two transport chains is achieved in that the two parallel deflection wheels are connected to each other via a continuous shaft.
  • the number of thumb pairs required depends on the one hand on the cycle sequence of the rolling stock rolling in and on the other hand on the speed of the transport chain.
  • one end of the thumb is fork-shaped with two transverse bores through which an axle bolt carrying the contact roller is inserted. With regard to noise reduction and surface protection, the contact roller is coated with a damping material.
  • the choice of the diameter of the contact roller does not depend on the diameter of the rolling stock to be transported. However, it must be selected with respect to the thumb so that the extreme extent of the contact roller in the case of the horizontal position of the thumb lies in the area of the rolled material which is already jammed below the path level of the grate. As a result, the roll can be immersed under the rolling stock that has already been jammed, without the roll lifting up or touching the rolling stock.
  • the device according to the invention consists of an inclined grate 1, which is formed from support frames 2.2 ', 3.3' and beams 4.4 '(Fig. 2).
  • the size of the inclination of the drain grate is characterized by an angle 6 and is approximately 5 degrees in this exemplary embodiment.
  • An endless transport chain 7 runs parallel to the drain grate 1 and is guided and driven by deflection rollers 8, 9 arranged at the ends of the drain grate 1.
  • the direction of transport of the rolling stock, symbolized here by two different sized pipes 10, 11, is indicated by an arrow 12.
  • three pivotable thumbs 13, 14, 15 are arranged on the transport chain 7, which run around the chain. The details of the thumb 13, 14, 15 are shown in FIG. 3.
  • the thumb 13 As soon as the thumb 13 has reached the area of the upper run of the transport chain 7, it folds down due to the weight of the differently divided masses and is thereby inclined. In this inclined position, it intercepts the rolling stock 10, 11 rolling from the left. Then it is guided in the direction of transport 12 until it strikes the fixed stop 16 or an already jammed good. During this stop, the thumb 14 is pressed below the path of the drain grate 1. In the area of the lower run of the transport chain 7, the thumb 15 is held parallel to the transport chain 7.
  • Figure 2 is a section of the device according to the invention along the line AA in Figure 1. So that the rolling stock is guided exactly parallel along the drain grate 1, a is at a fixed distance second transport chain 7 'arranged, for synchronizing the speed of the two transport chains 7,7' the guide wheels 9,9 'are connected to each other via a common shaft 17.
  • Figure 3 and Figure 4 show on an enlarged scale the details of the thumb 13 or thumb pair 13, 13 'and its arrangement on the transport chain 7, wherein Figure 4 is a section along the line BB in Figure 3.
  • the thumb 13 is designed as a solid block and essentially has a rectangular cross section (see FIG. 2).
  • Two web plates 19, 19 'welded to the outer plates 18, 18' of the transport chain 7 'together with the bushings 20, 20' arranged thereon form a bearing block which serves to receive the axis 21 carrying the two thumbs 13, 13 '.
  • a pin 22 is driven by the thumb 13,13' and the axis 21.
  • the axis 21 is offset from the center of gravity of the thumbs 13, 13 ', so that the thumbs 13, 13' stand up in the upper run due to the weight of the differently divided masses.
  • the thumb 13 has a recess 23 which extends from the long side 24 to over the central region of the thumb 13. This recess 23 is arranged so that the elongated pin 25 of the chain link engages in this recess 23.
  • the thumbs 13, 13 'are fork-like 26.26' and the contact roller 27, 27 ' is arranged in the respective fork.
  • the contact rollers 27, 27 ' are in constant contact with the surface of the rolling stock 10, 11 to be transported.
  • the one in the upper run Transport chain 7 is supported with its rollers 28 on a carrier 5. So that the thumb 13 cannot fold over in the area of the lower run, a pin 29 is driven into the welded-on web plate 19 to secure it. This pin 29 engages in a recess 30 of the thumb 13 arranged for this purpose, which extends from the upper longitudinal side 32 into the thumb 13. This also prevents the thumb 13 from lifting up in the region of the upper run when the thumb 13 is pressed by the rolling stock 10, 11 or by the fixed stop 16 below the path level of the drainage grate 1.
