Device for transporting and handling bar material in processing machines.

The invention relates to a device for transporting and handling bar material in further processing machines, For example a device for handling round profile bars made of metal, for example for grinding, turning, Peeling or smoothing.

In many cases there is a need for further processing machines for rod material a significant number of crane systems or manual workers be assigned to the handling of the rods to guide them through the machines, these for examination afterwards on the machining and to make further passes of the bars through the machines, which the first inspection not withstood above, prepare and perform.

It is an object of the invention to alleviate this problem.

In one aspect, the present invention provides one Device for transporting and handling bar material in processing machines with a feed station for feeding the bars one by one through the machines to a receiving station and with an actuator at the receiving station, in the case of successive rods is generally operable to pass the bars individually and sequentially to a waiting station for inspection and then to a voting station, the voting station operable to either feed a rod to the feeding station returned or put in a container, depending on what was observed at the inspection station Condition of the respective rod.

The rods are preferably moved continuously in the axial direction from the feed station to the receiving station, wherein the actuator lifts the bars further to the waiting station during their forward movement after they have been removed from the further processing Machine are free.

In particular, the actuating member can contain a number of pivoting arms which can be reciprocated and which in common Raise a particular pole at the receiving station and allow it to be against a shouldered section rolls down, whereupon the rod is stored on the waiting station when the arms are withdrawn, which for example by an equal number of stationary supports is formed. The shouldered portions of the arms are also designed to accommodate the preceding, Loosen the rod lying on the waiting station for a further movement to the voting station when the following rod is raised will.

The bars preferably follow a rectangular path of travel, with the selection station having a roller drive section, which is in front of control devices, which the correct Make a choice whereby the bars from the waiting station are driven axially to this control along a path, the one parallel to the path between feeding station and Receiving station. The rods roll, preferably under the action of gravity, along rails from the waiting station to the Roller drive section and from the controller to the feed station.

The control device itself can have two groups of components, which can be selected in terms of drive, around the rods to lift it further onto the rail for return or to lift it up for storage in the receptacle (collection bag), which in turn takes place under gravity.

In the following, the invention is explained in more detail with reference to an embodiment illustrated by way of example in the drawings. It shows:

Figure 4 shows a section along the line IV-IV of Figure 1, showing the reel drive section of the voting station; and

Figure 5 is a section along the line V-V of Figure 1,

which shows the control device at the voting station.

In Figure 1 is the device for transporting and handling illustrated and consists of a feed station 1, at which the bars by a grinding machine 2 - to a receiving station 3 are passed, the rods then first to a waiting station 4 and then to a selection station 5 a drive section 6 can be passed on. At the voting station 5, the rods are either deposited in a collecting pocket 7 or returned to the feed station 1 in a circuit.

In operation, bars or round material are used for grinding in Filed longitudinally across a rail 9, which slopes downward in the direction of stop arms 10, against which the rods are in contact (Figure 2). Such rods are illustrated in Figure 2, have been shown in Figure 1 for the purpose of a however, it has been omitted for a clearer illustration.

The selection of a bar for grinding is carried out by a known bar inlet mechanism which has a common Has axial drive lever 11, which is effective via a pivotable joint 12 to a number of conical

Raise selector levers 13 that extend the length of the rod. These selector levers lift the rod from the stop arms 10 free and allow them to work together Groups of drive rollers 14 running downwards. One such rod 15 is illustrated on these rollers. The conical ones Selector levers are then withdrawn.

While this transfer is being carried out, a series of pivotable spring arms 16, which also form a part this well-known lifting mechanism form, raised in order to pass through to allow the rod and then lowered onto it to allow the rod to contact the drive rollers to ensure.

In connection with this mechanism, however, provision is made for the adjustability of the stop arms 10 to rods to be able to handle different diameters, taking into account the fact that the end of the conical Selector lever 13 must be equally spaced between adjacent rods. This setting is supported by a single, with screw thread control arm 17 carried out, for all pivotable joints of all stop arms 10 can be operated together.

If now each rod is transferred to the drive rollers 14, it is driven by this helically in the direction and through the grinding machine 2 and occurs at the receiving station 3 off. Drive rollers 18 take over the drive at this station and spring arms 19 are again to that described Purpose provided, these two components forming the known rod outlet mechanism.

With separate reference to Figure 3 it can be seen that,

when the trailing end of the rod overflows a proximity switch or detector 20 (Figure 1), the spring arms are raised and a number of actuating arms 21 automatically the Raise the driven rod, such as rod 22, free of the drive rollers, whereupon the rod moves rolling down in the direction of a shouldered section 23 when the height of this section is above the height of a The number of stationary columns 24 at the waiting station increases. During this movement, the trailing ends 25 of the actuating arms push the preceding rod from the waiting station, i.e. the rod 26 by sliding it over a shoulder 27 onto the pillars 24, from where it is gravity-fed rolls along a rail 28 to the roller drive section 6 of the voting station.

In the meantime, after the arms 21 are withdrawn, the following rod 22 becomes on the pillars 24 of the waiting station held and rolls down to lie against shoulder 27.

The cycle is then repeated when the following bar is machined by the grinding machine.

At the voting station, the rod that arrives there is initially supported by a number of swivel arms loaded with weights 30 braked and then stopped when it strikes against a stop bracket 31. Drive rollers 32 that move continuously turn, then take over the drive of the rod and move it in the axial direction exactly to the selection station, any misalignment in the path of movement of the rod is corrected by guide plates 33 forming a channel define variable width.

The path that the rods then have to follow is selected by a control device which is under the control of a Operator stands and depending on the observed or measured state of the bar on the columns of the waiting station is operated. If the surface of the rods has not been sanded clean enough or not on the If the required dimensions have been ground, the bars must be returned for one more pass. If If the bars at the waiting station are in the correct condition, they must be placed in a collection bag in order to be stacked and transported away or transported for further processing, depending on what is required.

From Figure 5 it can be seen that when the trailing end of the rod has a proximity switch or detector 35 (Figure 1) overflows, and when the rod is to be returned in the circuit, a number of pivot arms 36 are automatically actuated and raise the rod free from the drive rollers 37. At that moment the rod is against a lip on the Hold these arms in extreme wedlock and then roll them under The effect of gravity on the rail 9 downwards and from here to the feed station. The pivot arms 36 are withdrawn, before the subsequent rod is transferred to this voting station.

Alternatively, if the rod is "good ¹¹ ", it is deposited in the seed pocket 7 in response to the actuation of a lever 39 provided with a conventional axial drive, which is operated via a hinge 40 to move the rod on a series of conical V ^r levers 41. These cones are bevelled in such a way that they eject the rod into the pocket 7 under the force of gravity.

Although the invention is exemplified with reference to the specific As has been described in the illustrated embodiment, it is apparent that various modifications or changes can be made can be made without departing from the basic concept of the invention. For example, bar infeed and leakage mechanisms are used that differ from the known forms illustrated in association with the invention differentiate to transport the rods to and from the machine and this can be especially for machines of the Be the case that are not, as in the above exemplary embodiment, grinding machines. More complicated facilities to adjust the stops (Figure 2) can be used and the control of this function as well as the input and the optional recirculation can also be carried out in a central electronic control will. Other forms of damping and braking of the rods than the weight-loaded arms (FIG. 4) can also be used be used.

HJizu comes because in the embodiment described all Rods 3/4 of the cycle go through that one other

Arrangement of the collection bag advantageous in certain applications can be, which depends on the existing crane systems, for example the collection bag in the area of the Roller drive sections of the voting station may be provided.

All of those mentioned in the description and in the drawings recognizable technical details are important for the invention.
