Description

The invention relates to a receiving device for foot plates according to the preamble of claim 1, a clamping conveyor unit according to the preamble of claim 15 and the use of a clamping conveyor unit according to claim 24. It is intended to foot plates of warning and guiding devices, which in particular the use of standardized footplates for traffic guidance and limitation in public transport.

In Europe, there are numerous road construction sites every year, which u. a. caused by road extensions and repair measures. In these cases, it is absolutely necessary to create a clear optical demarcation of the various traffic areas. In order to minimize traffic disruptions, warning and guidance systems are set up with the aim of ensuring clear traffic routing with high traffic safety. Site security is mainly carried out by specialized service companies. Every day, many kilometers of beacon systems may have to be moved in and out. Standard beacon systems, which are standardized in some European countries, have a dead weight of about 33 kg. With daily site signage, this leads to health problems of the staff and thus to a higher level of illness. For example, with a route length of 5,000 m approx. 250 beacon systems have to be positioned and cleared again after site closure. The total weight to be handled amounts to approx. 8,250 kg each. The construction and dismantling in current traffic, for example, to delineate a lane on a federal highway, represents a significant threat to the security personnel and road users dar. Especially for the lane securing the beacon systems are delivered to flatbed trucks or transported away. This Leitbaken and foot plates are often stored separately and secured. On the bed, the footplates are stacked manually on Europool pallets. This work is carried out without auxiliary equipment, whereby the human body comes to its load limits. The problem is the stacking of approximately 28 kilograms foot plates in bent and twisted state. These movements are ergonomically unfavorable and can lead to serious damage to the musculoskeletal system.

From the DE 41 01 954 A1 is a device for setting up and collecting road markings, in particular marking cones known. This document shows a receiving device comprising a centering device and a clamping conveyor unit, wherein the clamping conveyor unit has a rotatably mounted and driven clamping unit and a control rail. The clamping unit has two contact surfaces which correspond to a control rail. This recording device described is not suitable for receiving foot plates.

With the US 3,096,868 A a receiving device is disclosed which, however, can only be used to receive hay bales.

The object of the invention is to mechanize the inclusion of foot plates, in particular for warning and guidance devices, and to provide a recording device for foot plates available. In addition, to meet the requirements to be able to put the primary workplace of the security personnel from the road to the commercial vehicle and on the other to minimize the related heavy work in this respect. It is a further object of the invention for such a recording device according to the invention to provide an optimized clamping conveyor unit in this respect and to specify a corresponding use.

The object of the invention is achieved by a receiving device with the features of claim 1.

Essential to the invention is that the control rail causes a movement of at least one contact surface towards the base plate.

The recording device for foot plates according to the invention comprises at least one centering device and a clamping conveyor unit, wherein the clamping conveyor unit has at least one rotatably mounted and drivable clamping unit and at least one control rail, wherein the clamping unit has at least two contact surfaces, which correspond to at least one control rail.

The recording device according to the invention can basically be placed in all possible positions around a work machine or a commercial vehicle, for example analogously 6 shown. An expedient working speed of the working machine or of the commercial vehicle on which the receiving device is arranged is, as constant as possible, at least 5 km / h during the entire picking process. The on the floor (road, road) and in particular set up in a series foot plates are raised using the recording device, while traction. Located at an elevated level of this adhesion is solved, so that the raised Good from the receiving device removed, for example, manually or by a robot unit, is or to a subsequent unit, such as a continuous conveyor, can be handed over. Alternatively, the raised material can be deposited or transported on a storage surface, for example a loading area.

The recording device can in particular cover a specific work area. The workspace is the track or row in which the footplates are located. To ensure a safe recording, this area must be as small as possible for recording; ideally about the Fußplattenbreite.

The centering device, in particular an assembly with a funnel-shaped inlet centered the foot plates, in particular due to a self-motion, for example, driven by a working machine, in the required longitudinal position. After this centering, the respective foot plate passes over the transfer point to the clamping conveyor unit. This centering device consists in particular of two profiled rails, which are preferably provided with a curvature or edging. The arrangement to each other gives the funnel-shaped inlet. The maximum opening width of the inlet area determines the maximum working area of the centering. The width of the outlet area, which opens into the transfer point, is at least slightly wider than the maximum width of the base plate. Each of the two profile rails can be guided over the floor (road, roadway) by means of two 360 ° profile rail rollers. Thus, the profile rail rollers always have contact with the ground, a decoupling between the main frame and centering device is preferably installed. This decoupling is realized via a vertical thrust piece (height compensation) and an axis of rotation in the horizontal direction. The thrust piece is the connection between the main frame and the swivel joint. The hinge connects the rail with the thrust piece. The structural design of the thrust piece consists in particular of profiles that run into each other. Alternatively, standardized linear guides can also be used. The swivel joint is replaced by a classic bolted connection.

For another alternative solution, d. H. For example, other weight and speed ratios, another linear guide, in the working direction, is provided. This is necessary for the impact energy reduction during the centering process. This linear guide consists of standardized components and in particular an additional spring-damper element. The arrangement takes place between profile rail and swivel joint. On the profile rail inside, on which the foot plates slide off, wear attachments can be attached. These significantly reduce wear on the footplate.

The subclaims 2 to 14 further indicate features of the solution; without naming them conclusively.

It is preferred that the clamping unit of a segment, preferably a pinch wheel, or a plurality of segments, preferably clamping arms or parts of a multi-part pinch wheel consists.

If the control rail abuts on the one-piece or multi-part clamping unit, this causes a movement of at least one contact surface towards the material to be lifted. This process preferably begins with a contact surface, wherein subsequently at least one further is moved in this regard.

The desired clamping in the context of the invention, d. H. Producing a frictional connection between the contact surfaces and the material to be lifted, which allows a fixing and secure lifting, is realized by a movement of at least two contact surfaces, which are located on a clamping unit, towards the material to be lifted, here the base plate. This movement of the contact surfaces can be done differently according to the invention.

A first possibility is given in which the contact surfaces with respect to the clamping unit on which these contact surfaces are indirectly move. This is possible, for example, by at least two plungers, each with a contact surface, wherein the plunger can be moved with respect to the clamping unit.

A second possibility is given in which the respective contact surface, which is located in each case on another part of a multi-part clamping unit (directly), moves together with the respective part of the multipart clamping unit.

Further possibilities are made possible, for example, by a combination of the abovementioned possibilities.

A recording device according to the invention may also have a plurality of clamping units according to the invention within the meaning of the invention.

It is further preferred that the clamping conveyor unit has at least two rotatably mounted and drivable pinch wheels, each of which carries at least two plungers, more preferably six plungers, and each having a control rail corresponding to the pinch wheel. In this embodiment, a very uniform two-sided clamping is possible.

Alternatively, it is preferred that the clamping conveyor unit a rotatably mounted and driven Clamping wheel which carries a plurality of rams and has a control rail corresponding to the clamping wheel, and has a rotatably mounted disc wheel, without a corresponding control rail. The disk wheel does not move, at least not actively, towards the goods to be lifted; possibly by a resilience, especially ferderartiges, the disc wheel.

The disc wheel (without plunger) may have an elastic surface and / or be tapered outwardly.

It is further preferred that the clamping conveyor unit further has a particularly elastic wave washer. The corrugated sheet should be elastic at least in the areas where the contact surfaces touch the corrugated sheet. Another advantage lies in the large contact surface of the corrugated disk, so no gripper elements can get caught on the base plate.

The present invention encompasses both a solution with or a solution without a corrugated sheet. A recording of the footplate can be done independently of the beacon system distances.

In the solution without corrugated particular advantage is the uniformity with which the plunger can move in the guide through the backdrop.

It is further preferred that the device arranged downstream of the clamping conveyor unit has at least one continuous conveyor, a transfer element and / or a storage surface. By a transfer element between the clamping conveyor unit and a continuous conveyor this can be hung with more ground clearance to the roadway in the main frame. The Gurtrollendurchmesser the continuous conveyor plays an essential role. The continuous conveyor preferably has the same circumferential speed and now tries to pull the footplate. In support of this, the wheels push the foot plate all the way to its end and push it in the direction of the continuous conveyor. Thus, a secure transfer to the continuous conveyor, preferably a belt conveyor created. Preferably, guide elements are to be provided on the continuous conveyor, which prevent lateral slippage. The recording process runs continuously and can thus be carried out independently of the foot plate distances (on the road).

The object of the invention is also achieved by a clamping conveyor unit having the features according to claim 15 and by the use of this clamping conveyor unit according to claim 24.

Essential to the invention is that the control rail causes a movement of at least one contact surface towards the base plate.

A clamping conveyor unit according to the invention may, according to the invention, also have a plurality of clamping units, in particular arranged one after the other.

The subclaims 16 to 23 indicate further features of the solution, without finally naming them.

It is preferred that this clamping conveyor unit has a pinch wheel which carries a plurality of plungers and has a control rail corresponding to the pinch wheel, and a disc wheel or at least one pressing surface which serves as an abutment for the forces applied by the pinch wheel. The material to be lifted is thus fixed between the pinch wheel and on the other side by the disc wheel. The disc wheel does not have to be driven independently, but runs after fixing during clamping with. The disc wheel can also have another configuration according to the invention, but at least be a pressing surface.

Alternatively, it is preferred that the clamping conveyor unit has at least two rotatably mounted and drivable pinch wheels, which each carry at least two contact surfaces and each have a control rail corresponding to the pinch wheel. The material to be lifted is thus fixed between the two clamping wheels.

Furthermore, it is preferred that the contact surfaces, such as the plunger, are arranged over the circumference of the one-piece or multi-part pinch wheel of the type that their distance from the edge of the pinch wheel is determined by the maximum height of the plate-shaped body. In this case, the contact surfaces or at least some of them may be spaced differently from the outer edge of the clamping wheel. For example, the contact surfaces may be arranged on at least two circular paths, wherein the circular paths each have a different distance from the edge of the clamping disk or have a different amount of the distance measure.

In the following, the invention will be explained in more detail with reference to drawings. Each show in a schematic representation,

7 Clamping conveyor unit with clamping wheel and disc wheel.

In 1 a receiving device for foot plates is shown. All traffic control and barrier systems installed in the public traffic area must comply with the applicable technical delivery conditions. The Bakensystem consists of several components, the basis forms a foot plate, which gives it in different designs. Based on this, beacons are fixed in the base plate. Depending on requirements, the beacon can be supplemented by a warning light. The necessary power is supplied by a rechargeable battery, which is either attached directly to the luminaire or inserted in the footplate. The Bakenfuß is made in a conventional manner from a plastic recycling material. It is characterized by good coefficients of friction and high breaking strength. The foot plate weight is about 28 kg. The foot plate dimensions are given as approx. 800 mm × 400 mm × 120 mm (L × W × H). The foot plate is a standard series product, which has no attachment points or grommets for mechanical gripping. For gripping or clamping under adhesion, the lateral outer surfaces of the foot plate are available.

For example, the pinch wheel must rotate at 48 rpm to minimize the relative movements between the footplate and the corrugated wheel at a travel speed of 1.4 m / s (5 Km / h). The control rail presses some located on the circumference of the clamping wheel plunger controlled and over a well-defined area inwards. This results in a lifting of the rubber discs. In this area, a base plate located there can be clamped. The continued movement of the pinch wheels allows the clamped footplate to be raised until the plungers at the end of the control rail return to their original position and release. If the footplate is raised and is located above the following continuous conveyor with the first few millimeters, the dissolving process will start regularly.

The recording device for foot plates according to the invention consists at least of a centering device 2 and a clamp conveyor unit 3 , in this illustrated embodiment of two clamping conveyor units 3 , Each of these clamp conveyor units 3 includes, inter alia, a rotatably mounted and drivable clamping unit 3.1 and at least one control rail 4.1 , The clamping unit 3.1 consists of a segment, here a one-piece pinch wheel 3.11 ,

The centering device 2 and the clamping conveyor unit 3 are on a main frame 1 arranged.

As a basic carrier of the clamping unit 3.1 serves z. B. a circular metal or Hartgewebeeibe, which is provided on the outer periphery with holes. Depending on the gate geometry, plungers enter and leave these holes, which press, clamp and lift the foot plate against the outer surfaces.

In 2 is a further view of the recording device according to the invention for foot plates according to 1 shown. At the main frame 1 can be a transitional element 1.1 be arranged. The mobility of the footplate-receiving device is exemplified by one on the main frame 1 fixed chassis 1.2 realized which four movable wheels 1.21 own, which are pivotable by 360 °. The centering device 2 with a funnel-shaped inlet 2.7 centers the foot plates. After this centering, the respective footplate passes over the transfer point 2.8 to the clamping conveyor unit 3 , This centering device consists in particular of two profiled rails 2.1 , The arrangement to each other gives the funnel-shaped inlet 2.7 , The maximum opening width of the inlet area determines the maximum working area of the centering. The width of the transfer point 2.8 is at least slightly wider than the maximum width of the foot plate.

In 3 is a part of a centering of a footplate receiving device according to 1 and 2 shown.

The part shown consists of a rail 2.1 , which is provided with a curvature or edging. The profile rail 2.1 is made by means of two 360 ° profile rail rollers 2.2 led over the ground (street). So that the profile rail rollers 2.2 always have ground contact, is a decoupling between the main frame 1 and centering device 2 built-in. The decoupling is via a vertical thrust piece 2.6 (Height compensation approx. 100 mm) and realized a rotation axis in the horizontal direction. The thrust piece is the connection between the main frame 1 and swivel 2.4 , The swivel joint 2.4 connects the profile rail 2.1 with the vertical thrust piece 2.6 , The execution of the thrust piece 2.6 consists of profiles that run into each other.

Alternatively, standardized linear guides can also be used. The swivel joint 2.4 is represented by a classic bolted connection. For higher working speeds is a horizontal thrust piece 2.3 , in working direction, available. This is necessary for the impact energy reduction during the centering process. The linear guide (thrust piece) consists of standardized elements and an additional spring-damper element 2.5 , The arrangement takes place between profile rail 2.1 and swivel 2.4 ,

The 4a shows the clamping conveyor unit 3 with two clamping wheels and with an external drive 3.5 , The drive 3.5 can be done hydraulically, pneumatically or electrically. The power transmission can be done via a transmission, as well as directly. Another drive variant is to run the clamping wheels on the outer circumference on the road and thus to put them in rotation.

4b shows a pinch wheel 3.1 from the inside (clamping side). The wave washer 3.2 is in the middle with a flange 3.6 on the pinch wheel 3.1 attached. At least on the outer circumference, the corrugated sheet can 3.2 from the pinch wheel 3.1 take off. Will be a pestle 3.3 , which protrudes in the idle state on the Klemmradaußenseite moves so pushes this against the corrugated wheel 3.2 and lifts them by a defined amount from the pinch wheel 3.1 from. The driven clamping disc 3.1 is through a flexible wave washer 3.2 as a transmission element between plunger 3.3 and footplate added. This will ensure that the plunger 3.3 does not hit the footplate directly. The wave washer 3.2 compensates for differences in height, ie heels and depressions alongside the footplate. The occurring relative movements between the corrugated sheet 3.2 and the foot plate thus spread over a larger area. The wave washer 3.2 is preferably made of a material which wears much faster than the foot plate. The wave washer 3.2 lies directly on the clamping disc 3.1 and can stand out from it (outwards). If an unwanted lifting should be avoided, the corrugated washer 3.2 be equipped with spring elements. The components clamping disc 3.1 , Corrugated disk 3.2 and pestles 3.3 can as a clamping conveyor unit 3 be summarized. The clamping conveyor unit 3 , which is tuned in the embodiment of the standardized foot plate, has a diameter of about 600 mm and is seen in the direction of the centering device 2 downstream.

4c shows the pinch wheel 3.1 from the outside. At the outer periphery of the pinch wheel 3.1 distributed, there are several pestles 3.3 , here twelve pestles 3.3 which end up with a ball roller 3.4 equipped, each carrying a contact surface. All pestles 3.3 are arranged at the same distance from the edge. (For the purposes of the invention, the plunger 3.3 or the contact surfaces also have a different distance from the edge, for example, distributed over two different distances.) Between ball roller 3.4 and pinch wheel 3.1 is the compression spring 3:41 placed the respective pestle 3.3 pushes outwards, ie from the pinch wheel 3.1 , path. The pestles 3.3 move in the usual sliding or rolling guides, in through holes, in the clamping wheel 3.1 are used. The wave washer 3.2 , For example, an elastic rubber disc is centered on the inside of the clamping unit, here the pinch wheel 3.1 , attached and at least in the region of the outer circumference of the inside of the clamping wheel 3.1 , in particular by the plunger movement, from the inner surface of the clamping wheel 3.1 lifted. (This plunger movement is caused by the contact surface of the ball roller 3.4 on control rail 4.1 , in 4 c not shown, causing a portion of the plunger 3.3 through the bore of the pinch wheel 3.1 is pressed and over the inner surface of the pinch wheel 3.1 protrudes. From the Klemmradmitte protrudes a wave 3.6 , which is connected on the opposite side with a flange on the clamping wheel. On the shaft is, for example, a sprocket of the drive 3.5 ,

4d shows a control rail 4.1 with its linkage, which on the main frame, in 4d not shown, is attached. The control rail 4.1 is for the operation of itself in the clamping wheel 3.1 located ram 3.3 responsible. So that the ram 3.3 safely reach the control rail, each is a ramp-shaped inlet zone 4.11 and run-off zone 4.12 appropriate. To avoid overloading this assembly, due to the dimensional tolerances of foot plates, this is movably mounted. Here is the control rail 4.1 with a spring-damper element 4.2 equipped. (The tolerance compensation can alternatively be carried out according to the invention with a resilient plunger and a rigid control rail.) The control rail 4.1 may consist of a metallic or non-metallic material. The control rail 4.1 actuates the plungers 33 on a circumferential length of about 50 °, in particular depending on the diameter of the clamping wheel 3.1 and desired lifting height.

The 5 shows an alternative embodiment of a clamping unit of the clamping conveyor unit. The clamping unit consists of several segments, here a multi-part pinch wheel 3.12 , It essentially consists of at least 6 segments, which together form a disc shape. The diameter of the resulting wheel is for example for the foot plates described in the range of about 500-800 mm. The segments consist, at least in part, of flexible metallic or non-metallic materials which have a resilience (spring elasticity) analogous to a spring. This ensures that the respective segment after deflection, caused by the contact with the control rail, springs back into its original position. The segments of the multipart pinch wheel 3.12 are fixed around a flange which is connected to a rotatable shaft. The segments can be moved independently of one another in the axial direction. The movement can take place in the segment or on the mounting on the flange, depending on the material. For a controlled and continuous movement is at least one (segment) pressure roller 4.11 , which acts as a control rail arranged. The diameter of this pressure roller 4.11 is about 60-120 mm. The lifting height of the conveyed material is dependent, in particular, on the number of segments and the number of pressure rollers. In the 5 The solution shown does not have a wave washer. An alternative embodiment of a clamping unit of the clamping conveyor unit, in 5 not shown, can be equipped in the context of the invention with an elastic wave washer, in particular to bridge the paragraphs / height differences.

Operation:

By driving the pinch wheel, the individual segments pass through one or more pressure rollers and thereby undergo a movement / deflection. This movement causes in conjunction with a suitable counter-disc (identical or rigid) the clamping operation. The drive can with a drive unit and a rigid shaft, whereupon both pinch wheels 3.12 be realized. For the recording of the entire beacon system, a rigid shaft can not be used, two drive units or a non-active disk wheel are required.

In 6 is a mobile insert unit for receiving and transporting warning and Leiteinrichtungen with an integrated recording device according to the invention 5 , at least for foot plates, shown in a schematic representation. The mobility of the unit is through a flatbed truck 6 guaranteed. The flatbed truck 6 owns a loading area, on which a magazine 7 for beacons or at least foot plates is shown. The recording device 5 , at least for foot plates, is next to the truck 6 arranged and connected to this. This mobile recording device 5 has a clamping conveyor unit according to the invention and a centering device. In the working area of the recording device 5 are two beacons, each with a foot plate shown. The recording device 5 can subordinate, as in 6 shown, a continuous conveyor 8th be arranged.

The pinch wheel rotates in this embodiment at about 48 U / min, so that at a speed of 1.4 m / s (5 Km / h), the relative movement between the base plate and corrugated disk is kept as low as possible. The control rail presses some located on the circumference of the clamping wheel plunger controlled and over a well-defined area inwards. This results in a lifting of the corrugated disk, for example, designed as a rubber disc. In this area, a base plate located there can be clamped. The continued movement of the pinch wheels or pinch wheel and disk wheel allows the clamped footplate to be raised until the tappets at the end of the control rail, i. H. the exit area, return to their original position and solve. If the foot plate is raised and is located over the following continuous conveyor with the first millimeters, the release process begins.

In 7 is a partial view of a clamping conveyor unit 3 with a pinch wheel 3.1 and a disc wheel 3.7 shown. The clamping conveyor unit 3 has a rotatably mounted and angetriebnes pinch wheel 3.1 , which has several pestles 3.3 carries and a clamping wheel corresponding to the control rail, in 7 not shown. As an abutment is a rotatably mounted disc wheel 3.7 , without corresponding control rail and without independent drive arranged. Both at the pinch wheel 3.1 and at the disc wheel 3.7 in each case a corrugated disk is arranged in the manner described.
