Description

Magnetic counter

The invention relates to a magnetic device which is used for Preparing and removing a predetermined number of bars from a running one Location that is located on a plurality of transporters that are on the bars of the same type and which are made of magnetic material, or on a magnetic field react.

It is an automatic or semi-automatic system, which advantageously serves to ensure a continuous supply of cut to length To accomplish rods, which may also have to be straightened in the same way.

The bars produced here can be of any kind, i.e. rolled, drawn, profiled or extruded and can have any cross-section.

They are advantageously made of magnetic material or of a material which reacts to the action of a magnetic field or a magnetic element.

If the bars are continuously fed and this feed faster occurs as the derivation, an accumulation of the rods will occur and at least a continuous layer of it.

One must therefore separate these rods in the desired quantities and dissipate.

This continuous feed can be carried out with a plurality of transporters take place, e.g. by means of chains or rollers, which then e.g. the bars of a pair of scissors and / or a straightening device and / or other devices, e.g. a device for strength testing, a device for counting the bars is described in the applicant's Italian patent no. 1,018,453.

This known device is used to provide a predetermined number of To remove bars from a running shift, this running shift is fed on a plurality of Eransporters and where it is done that the rods were held in at least two racks and one A plurality of separators is arranged1 which are provided perpendicular to the transporters and further a plurality of movable arms in parallel with said transporters work.

This known device has several disadvantages, chiefly in that the transport bed has considerable dimensions, especially there where the number of bars to be removed is considerable.

According to the proposal of the present invention, the task is with Using a magnetic device to count the bars, in a very advantageous way Solved in a wise way, it is eliminated quickly and with remarkable operational reliability carried out and the operations much simplified1 so that whatever the conditions the work is feasible.

In doing so, the rods of the magnetic material are set to the desired one Tailored to measure and if necessary the same straightened and over a roller line fed to a favorable stop. With the help of the chains and the climbing sports trails the bar is moved from the approaching roller train to the desired level. The rods are placed on appropriate supports.

After a proposed solution, a rotating polygonal Walse Find use and, according to a variant, a plurality of devices are switched on to cause the rods to spread.

According to a further variant, twisting mechanisms can also be used use or other similar facilities4.

Finally, you can also work together with one or the other Device and the above-mentioned twisting mechanism a vibrating Blade that is essentially vertically effective, use the one with permanent magnetic or electromagnetic devices can work together.

According to a further variant, it is also advantageous to have a stop to be provided, which is optionally designed to be elastic.

Permanent magnetic or electromagnetic devices are used advantageously provided in a position in which it engages the rods Form magnetic field. Such magnetic devices can be advantageous in vertical Position can be arranged.

It is also advantageous to provide devices for transverse movement, which cooperate with the upper zone of the rods during the expansion phase the same. Finally, it is also advantageous to have an upper guide at the exit to prevent the clamps from overlapping during the discharge phase.

By the action of the twisting mechanism as a result of the magnetic Beldes, the poles come to each other to reject so to form a fan.

Finally, it is advantageous that the interaction of the magnetic Means with the rods an operative connection with a magnetic position north a magnetic position south is made possible.

Through the interaction of the twisting mechanism, the vibrating Blades and the magnetic device with the rods, the advantage arises, that the bars hit one another with their heads.

A cart fitted with a payment device for bars and with a shovel for separating, can go against the flow of the incoming bars be set in motion. The cart can run above or below the bars The counter that determines the number of bars required can den Stop the trolley and use the shovel to separate the counted bars from the others put into action. The counting device can with the aid of light beams work together with at least one photocell. All of these counters can be transported by the cart.

Another variant provides that the light source from the synchronized Movement of the cart is controlled9 which carries the photocell or vice versa.

According to a further variant, a light source can be ent long Attaching the operation of the cart0 Another suggestion is to use the cart to move in any way and the operating commands can be electrical, be done hydraulically, pneumatically or in some other way.

The cart can be equipped with a lifting device that suitable - is to temporarily trigger separation movements to temporarily create a bundle of rods to be separated from the others.-When the corresponding rods are separated the cart reverses the movement until there is a free longitudinal movement for the separation arrives in the rest position or other longitudinal separators in the rest position for achieve this purpose.

In this case the cart comes to a standstill and the lifting devices and the separating device are separated from the free translational separators in Action brought, while at the same time the separation shovels at low points he follows.

The devices for translational separation are advantageous Elements for two positions, one position being used so in the rods to intervene that a mechanical division. into a group of rod bundles and other takes place while the andore position the device of longitudinal separation concerns and does not engage in the rods and affects the rest position. The longitudinal separation is advantageously installed on a chain that is closed in a ring.

Once raised, the 'facility is in progress of separation thus characterizing and isolating the group of bars that have just been counted, the carts resumes movement in the direction of computation, repeating as described for all poles raised on the supports.

If the last bars counted do not add up to the desired number, the cycle repeats itself and the missing rods become out of the position of the rods taken out.

Eventual accumulation will complete this bundle or by other analogous collecting methods when the whole layer of the bars is counted is, you lower the supports and all rods come into contact with the circulating chains, the first teeth of which show progressive separation. The ongoing Chains and the chain with the separating device promote the position of the counted bars against the ejector arms.

The chain with the separators is advantageously adjusted with it a higher speed than the speed of the rotating chain, whence the correspondence with the previous unloading of a limited part the rods are given, which are already united in bundles.

Another variant stipulates that the chains that run away do not exist Silence when the rods come to the outer limit of the carrier while the chain with the separating device continues its course until the very end of the counted rods in the receiving device of the bundle rolls.

When a bundle has rolled into the first collector, set the chain with the separators is silent and the ejection arms begin to eject cycle of counted levels.

This cycle is carried out according to a progressive sequence, as these arms rise one by one.

When the first bundle enters the transducer, contact is made and is separated, it can then find its way consecutive Continue binding operations that are not described. Hardly have If the transducers are set higher, they place the revolving chains and the chain with them the separation means in motion, which then carries out the process for a second bundle repeat, if necessary according to one or the other variant.

While the revolving chains and the chain with the device for As the separation of the paid bundles becomes free, one another follows Cycle of counting and separating the bars.

So it is up to you to find and concretise the counting of the bars prepare magnetically and separate a number of predetermined rods of a continuous layer, this continuous layer on a plurality is guided by transport devices, the rods of any Type, advantageously of magnetic material or of such, which reacts in magnetic fields, the procedure according to the invention being such that the colliding rods cooperate in the phase of expansion to form a fan with at least one twisting mechanism, vibrating blade devices and at least one magnetic field and further means for the transverse movement of the rods, these devices cooperating with the rods, possibly advantageously with switching on a stop, a movable cart, cooperating with a counting device for the bars, with a separating shovel that temporarily acts as well as facilities for raising and singling out, these interact with chains, and eventually lead to a collection point where conveyor arms are provided.

According to the invention, a twisting mechanism can be provided and for this purpose a multi-sided, motorized roller 6 which uses a number of teeth; if necessary, by means of vibrating blades, magnetic fields that at least have a polarity of interest to the rods, transverse devices the twisting mechanism is formed for the rod, possibly elastic gowns According to a further proposal of the invention is a stop which, if necessary is elastic, provided.

According to the invention you can also proceed so that for counting and Separating the rods a movable cart, the at least parts of the counting device for the rods, a separating shovel with moving device, devices for temporary lifting and adjusting, moving devices and closed chains, cooperating with the cart, shovel and chute are provided; if necessary, in cooperation with the abbot, the counted and separated Rods blades arranged against overlay.

Another design according to the invention provides that ifl the zone the final separation and discharge, in cooperation with the separation facility a number of conveyor arms are arranged.

Further features of the invention emerge from the following description of an embodiment in connection with the drawing and the claims.

It shows, in schematic sketches, Figure 1 is a plan view of a Device according to the invention, FIG. 2 shows a side view of the device according to FIG 1, Figure 3 is a side view of the intermediate zone, Figure 4 is a variant according to the Proposal of the invention, FIG. 5 shows a twisting mechanism as shown in FIG is shown, Figure 6 the mechanism of Figure 5 in side view, Figure 7 a Cart in side view and FIG. 8 a vertical section through a cart and the chain that carries the continuous separation devices.

The figures show the same parts or parts with the same functions denoted by the same numerals.

In Figure 1 is a longitudinally extending roller train 11 provided with a shock absorber 12 at one end, around the abutting there Rods 13 to be able to stop.

To obtain a layer 113 of rods 13 (or if once rods 13, obtained by cutting to size from a long rod were), stand out the revolving chains 14 to what by erectable Groups 114 are carried out, which set up this chain 14 simultaneously and in a coordinated manner. These liftable driven chains 14, once lifted, add to the layer to set the rods 19 in rotation and to move to the side.

This lifting causes the chains 14 to be level, possibly inclined, form, with the side drive displacing the position 113 of the rods 13, according to arrow 15 until layer 113 is in an intermediate zone 16 for counting and segregation comes.

This zone 16 for counting and separating is provided with a feed surface Equipped vertically movable, including a number of cross members 17 are used cooperate with known groups 1, which are provided perpendicular thereto. By doing In the present example, each group 18 consists of a jack 19, which is attached to the foundation 49 is attached.

In the present design, the rod 20 carries the lifter 1 on its End of a roller or a ball joint 21, which cooperates with an arm 22, rotatable about a horizontal axis -at the end, while the other end of the arm 20 engages on the corresponding cross member 17.

The arm 22 is substantially horizontal when the feed plane 117 is in the lowered position, and is then inclined when the plane 117 is in the raised position. In the example of FIG. 4 there is 16 in zone a stop 23 is provided, which is advantageous, but not absolutely necessary, vibrating is and at the end of the feed plane 117 is located. The stop 23 is in detn Example vibrating and carried by an arm 24 that is anchored pivotably at 25 on the foundation 49.

The stop 23 can have a buffer part 26 at its outermost end, the frontal with a lining 27 in rubber or another material which Absorbs disturbances, which emanate from the abutting rods 13, is provided.

The stop 23 is provided vibrating in the example shown and can be provided with a group of known equipment, e.g. with a Auxiliary motor 28, which via a connecting rod 29, which is connected to the oscillating arm 24 in 30 attacks, be effective. The connecting rod 29 can e.g.

be eccentric adjustable.

The vibration emanating from the motor 28 can, with the aid of the element 26 are transferred to the ends of the rods 13.

This transmitted to the rods 13 vibrations can with a Cooperate twisting mechanism, which in the present examples in the Figures 1 and 2, embodied by a motorized polygonal roller.

Such a multi-edged motorized roller 31 drives the bars 13 to a vertical hop, the frequency of which expands to a fan of the Rods 13 facilitated.

As a variant compared to the motor-driven multi-edged roller 31 you can also arrange a chain 60 with widened teeth 62, or you can see appropriate twisting mechanisms.

In FIGS. 4 to 6 there is a variant 131 of the polygonal roller 31 provided which takes over the function of the twisting mechanism 31. According to this variation is the twisting mechanism 31 of the figures 4,5 and 6 d'urc; h realized a foldable body 58 which can be pivoted about a Axis 57 is arranged and is operated vnn a lifter 55, which by means of a Lever 56 takes effect. The body 58 can be substantially in a vertical plane be movable and located above or below the rods 13. Above that Body 58 is a chain 60 with a limiter of elongation 61 arranged, the spacer pins 62 has.

This chain 60 has an anchorage 19 with the Weber 64, suitable to let the chain 60 slide on the guide 66 up to the stop 65.

Instead of the chain 60, other systems or devices, such as Pantographs, racks, etc., etc. are used as far as devices are concerned acts that serve more or less to rotate the layer 113 of the rods 13 can.

When layer 113 is formed, the closed chain is lifted 60 so that their teeth enter between the rods 13. Then you press the Lifter 64, which rotates the chain 60 according to the arrow 63 (Figure 5) and rotates the Rods 13.

Instead of the lifter 64, you can also use an endless screw, a rack or provide other similar means.

Once the rods 13 are twisted, the mechanism is 131 without affecting the same rods. Magnets act with the plane of the carrier 117 32 together, which form a magnetic field and advantageously a lowered rest position and form an elevated working position. the Magnetic fields 32 can be present in the singular or plural.

Cooperating with the magnetic fields 32 is a vibrating blade 33 is provided which can be actuated by a drive 34, for example a motor 35, wherein the drive can take place via an eccentric 29 and a connecting rod 36, so that thereby a substantially vertical vibration of the blade 33 is brought about. the Eccentricity through the connecting rod 29 can be changed.

The vibrating blade 33 can be arranged in, center, or side two or more vibrating blades 33 may also be provided in this ball are within the magnetic field 32.

Nan can let two magnetic fields 32 interact, which are opposite act on the rods 13.

In cooperation with the zone 16 of the separation and counting during of the operation of lifting the rods 13, a device 73 is transverse Bar provided that cooperates with the upper part of the bars 13. This transverse Devices 73 are deactivated, e.g. by means of a lifter 75 or other similar means Middle. The transverse means 73 may comprise elastic means which serve to absorb any oscillations or vibrations and can do them elastic internals 74 be attached frontally or in between.

At the exit of zone 16 and with the zone of removal of the bundles of the counted rods, one can attach overlapping blades 76, which can be solid or be arranged elastically in some way. In the example of Figure 6 are the blades 76 oscillate in 77 and are opposed to 78 put elastic Facilities marked.

The rotation of the polygonal roller 31 makes one hop of the rods 13 brought about, or by the separating chain 60 if necessary in cooperation with the vibration of the stop 23 and / or the vibrating blade 33 will be spread the bars. This tendency to propagate is due to the magnetic field 32 fixed.

Thanks to this multiplicity of effects, one causes a fanning out of the rods 13, which are stabilized, as shown in particular with respect to FIG the zone 16 can be taken. The magnetic devices 32 in the structure of Magnetic fields can be operated by means of permanent magnets or electromagnets and can be arranged e.g. vertically by means of the lifters 67, which are provided with the tabs ffl can work together, via the parallelogram 69, what in the example shown results in a stable device by means of the tabs 70.

If the rods 13 are twisted and fanned out, they remain advantageously the magnetic effects are maintained and the cart 37 comes into action, which is provided is with devices for pulling, devices for steering, which are not shown further so that they cannot be further described in the present fold, Der Karren 37 runs transversely under the feed level with the aid of guides 137 (FIG. 8) provided the rods 13. In the example shown, a drive motor 50 is for the cart 37 provided. The cart 37 can of course also move above the rods 13 will.

The cart 37 is equipped with counting devices for the bars, e.g. with a kind of photocell 71, connected and subject to the controls of the Karrens 37.

The means for counting 71 can be of various types, such as e.g. a photocell, magnetic measuring devices, micro-measuring devices and the like. Such counting devices 71 for the rods 13 can be used as transmitting and receiving devices be provided on the cart 37. Such transmission devices can be used during the whole operation process of the cart 37 be effective. Nan can also send this and make receiving devices movable and connect to the cart 37 or possibly received independently. These and other possible variants can be used here.

In the example explained here, the cart 37 is with a separating shovel 38 provided, with a device 71 for counting the bars 13 and with a mechanical Device for lifting 51. A jack 41 can be attached to the cart 37, the facility for segregation and temporary transfer 40 are ordered to us, possibly also with the lever 72.

The cart 37 cooperates with at least one chain 39 that is provided transversely to the rods 13, which is closed and a plurality of advancing separators 40, which are arranged on the chain 39. These Disposal transfers 40 are made with the aid of the jack 41 mounted on the cart 37 is anchored, liftable. The device 40 is normally below the bars 13 and is placed in an interference position with the bars by the cart 37 13 brought when they are lifted.

There are also sliding devices 45 provided, which the separating device 40 put back under the rods 13 before they reach the layer 113.

When the bars 13 have been moved to a fan, moves the cart 37 against the rolling train 11 and the counter 71 for the bars 13 counts the number of predetermined bars 13.

After the count has been carried out, the carriage stops and the bucket 38 stops is raised by operating the jack 51.

The lifting of the bucket 38 occurs between the last counted Bar 13 and the first bar to be counted 13.

When the bucket 38 is raised, the cart 37 reverses one way To counter separation device 40, which is in the rest position. In this At this point, the cart 37 stops and causes the lifter 41 to raise the device 40 and also causes the bucket 38 to descend.

The cart 37 starts moving again in the direction of the counting device on and when the count is done, the scoop 38 rises in this way separates the number of predetermined rods 13 from the rest of the remaining rods, and this continues over the whole situation 113o If so the whole situation 113 the Rods 13 is counted and has been separated into bundles 52, the carriers lower 179 lowering the rods 13 in this way, onto a transport chain 42, which runs parallel runs to chain 39.

The rotating chain 42 may have its top surface knurled have and / or possibly be equipped with magnetic devices, so that when the supports 17 are lowered, the chains 42 change the position of the fan occupy, as this is concretized in the position 113 of the bars 13 of the cart 37 in cooperation with the separation device 40.

The revolving chains 42 and the chain 39 carry the separation devices ~ 40 and then transport the bundles 52 against the collection oil container 53.

The chains 42 stop when the first bundle 52 on the outer Limitation of the door carrier 54 arrives.

The chain 39 with the devices of the separation, however, continues its course continues until the 'separated end portion of the first bundle 52 in the receptacle 53 is rolled, held up by the collecting receptacle 44.

The collecting container 53 can be arranged on an inclined plane 54 that carries a system for binding or for other functions that do not are shown. At this point the chain 39 with the separators 40 stops and the conveyor arms 43 begin the phase of separating the bars 13, in this way the first bundle 52 from the rods 13, then making the second bundle 52.

The conveyor arms 43 can perform a circular arc in the one shown Example that lies axially to the rods 13 of the bundles 52.

The conveyor arms 43 are anchored to the foundation in an oscillating manner Oscillating Ac'hsön 143, perpendicular to the rods 13.

The upper part of the conveyor arms 43 is designed so that it is between one bundle 52 and another can wedge, thereby spacing the bundles can cause. The conveyor arms 43 are continuously operated so that they do this come to be lifted by the interaction-with the separators 40, so that the extension between the bundles is more in - the depth between the rods 13 goes.

If the extension by the first conveyor arm 43 is unsuccessful, one can trowel the second conveyor arm 43 and thus TO a complete separation of the first Get bundle 52 of the following. The conveyor arms 43 are advantageous in any way drivable.

So we have the process that the cycle of the conveyor arms 43 concretized in a raising according to a progressive sequence, with these arms 43 get up one at a time and wedge yourself in the transition created by the previous one, o The first counted and separated bundle moves towards picker 44 and from there it sets on his way to further operations.

No sooner have the rod receivers 44 let the first bundle 52 pass, the revolving chains 42 and the chain 39 with the separators 40 begin Repetition of the cycle for the subsequent bundle 52.

Meanwhile, the lowered supports 17 come back into the support position back and a new layer of poles spread to the fan arrives and is counted in the manner previously described.

The separators 40 of the endless chain 39 lips around, if they are on the other Arrive at the end of this chain with a slide 45 that attaches to the straps of this chain 39 is anchored.

According to the invention, the device is also on the outside of the Entrance level 10 is provided, this arrival level also for unloading if necessary can be used.

This emergency dump 46 is formed by a plurality of shovels 47, which are arranged transversely to the roller line 11, including a number of actuating devices comes, which are not shown, of course also a plurality of emergency receptacles 48. The inventive solution described here is a preferred design, however Further solution ideas are naturally possible without leaving the scope of the invention to fall out.
