Description

The invention relates to a method for controlling or regulating the clamp force of clamp arms moved against each other by a drive a transport device for individual or a group of like Transport goods taking into account the strength of the transport goods.

When transporting goods using a clamped arm Transport equipment, it is always problematic to transport goods reliably clamped and falling out when lifting, To prevent transportation and settling. This is also discussed below in In connection with a discussion of the prior art visible become. Now it would be conceivable to increase such a risk to counteract the clamping force. But that is in turn the pressure strength of the transport goods and / or their packaging Opposing clamping forces. Individual aspects of this are discussed in the Detailed description discussed in more detail. So it's about one Compromise between the properties and possibilities of the Trans port equipment and the mechanical properties of the transported goods to find. Finding such a compromise is because of the very However, numerous influencing factors are difficult.  

DE 908 471 C is a forklift with gripper or clamp poor known, in which the clamping force depends on the weight alone sets. This is done by a mirror-symmetrical arrangement of angle levers, on one lever arm of which the lifting force acts and whose other lever arms act on jaws that are in their centers are articulated and on the goods in the form of boxes stack act. Existing tension springs are not used to limit the Clamping force, but for pushing back the clamp arms that only on the bottom boxes act. This leads to the fact that with a Increasing the stack weight or the stack height increases the clamping force automatically increases without taking into account the strength of the lower boxes is taken. So the change in clamping force would be only possible by converting to other angle levers, which is the case with one economic operation of such devices is not responsible. With the on only clamps can be swiveled on the clamp arms Stacked boxes are transported, on both lever arms of the clamp bake at the same time. The bracket effect is therefore positive sig reinforced, d. that is, the jaws have spikes or spikes that Depending on the weight, penetrate the goods to be transported and damage them The reusability of packaging is therefore considerable limited. There is a coordination on the characteristics of the transport goods therefore also not possible.

From DE 38 01 133 C2 an attachment for a lift truck is known, in which the so-called depth of entry of the transported goods into the clamp arms determined by light barriers and / or ultrasound and the clamping force of the hydraulic drive is controlled in such a way that the entry depth maximum clamping force determined in stages. However, this is a purely geome trical solution, in which other characteristics of the cargo, in particular whose weight and strength are not taken into account. Out For safety reasons, the graduated clamping forces must also be very high can be set high.

EP 0 443 998 A1 and EP 0 664 272 A2 are transport devices lines known with clamp arms, in which a test stroke was first carried out  must be to check whether the cargo, preferred wise paper rolls for printers, slip in the clamp arms. This sliding process is detected by a feeler roller, which in one of the Bracket arms is arranged and the angle of rotation of the hydraulic drive controls in such a way that the clamping force when slipping is increased until the slipping no longer occurs. With the object EP 0 664 272 A2 describes the slip detection by an additional device-side recording of the weight of the transported goods supplemented by a Limitation of the clamping force according to weight and any Cause the goods to slide.

In none of the known cases is the transport device characteristic data communicated about the property and nature of the goods being transported.

From the following publications, it is known to assign the trans port goods and / or their parking space code devices in the form of bar codes, plain text labels, imprints and trans ponders that provide information about the following characteristics:

• a) identification, logistics and shipment control,
• b) warehouse management, inventory and billing,
• c) Production and process control, e.g. B. in car paint shops,
• d) healthcare,
• e) container cycles, recycling,
• f) location of storage or parking spaces (storage location marking),
• g) material flow and quality control,
• h) article numbers,
• i) incoming and outgoing goods at the sender and recipient,
• j) pallet identifier,
• k) optimization of the routes,
• l) Identification of vehicles for long-distance transport.

It is also known for these purposes, industrial trucks, for. B. fork and Forklift truck, beyond an "air" interface with appropriate sensors to provide, e.g. B. with bar code and plain text readers, transmitters and  Receivers for signals to and from transponders. In the last one mentioned case of electronic data transmission in the hall floor Transponders can also be arranged by the transmitter and receiver be located under the vehicle.

Three exemplary embodiments and their mode of operation are explained in more detail below with reference to FIGS. 1 to 5.

Show it:

Fig. 1 is a plan view of a first embodiment with a lift truck having a transport device with horizontally in the direction of projecting clip arms in cooperation with a cargo or more transport goods,

Fig. 2 is a side view of a second embodiment of a suspended transporting means,

Fig. 3 is a frontal view of the subject of Fig. 2 in the direction of arrow III in Fig. 2,

Fig. 4 is a side view of a third embodiment with a rotatable transport device for cylindrical transport, for. B. a paper roll for printing presses and

Fig. 5 is a schematic diagram of a control arrangement for the exporting approximately examples of FIGS. 1, 2/3 and 4.

In Fig. 1 is designed as a forklift truck 1 with a telescopic mast 2 and a lifting carriage 3 , to which a transport device 4 is attached with two bracket arms 5 , which are arranged mirror-symmetrically to a central longitudinal axis of the forklift. In front of the forklift is a cargo 6 (thickly outlined), which can also consist of four individual cargo 6 a, 6 b, 6 c and 6 d, which are arranged in two rows. Such an arrangement is described in DE 38 01 133 C2, which is expressly included in the disclosure content of this property right. This document also discloses the hydraulic drive which is integrated in the transport device 4 and is therefore no longer described in detail here.

It is also important in such an arrangement that the entry depth "T" does not exceed or fall below a minimum. It would be dangerous B. in the shown two-row arrangement of four items of transport an entry depth "T2" as indicated by the dashed lines: Here, the front row with the items 6 c and 6 d would be reliably clamped, but not the rear row with the items to be transported 6 a and 6 b, which could slip out of the clamp arms 5 or tip out when the load is lifted. Analogous considerations also apply to a single large cargo 6 . Here is z. B. meaning that the edges of a package due to their angular position have a greater resistance to deformation than the walls of the package.

On the lifting carriage or on the transport device, a receiver 8 is now attached, the optical axis of which can either be pivoted by an angle ".alpha." Or which has a corresponding viewing angle and through which the front of the transported goods 6 or the transported goods 6 c and 6 d are scanned can be attached to which code devices 9 are attached. These can either consist of a printed or glued strip code (bar code) or a plain text or a transponder that has at least characteristic data about the minimum and the maximum permissible clamping force on the special transport goods 6 , 6 a, 6 b, 6 c and 6 d contains. The transponder can be a "read-only" transponder or a writable transponder. In any case, the receiver 8 also contains a transmitter which retrieves the data stored in the transponder and / or stores new data. A light source is expediently assigned to the receiver for reading bar codes or plain text.

Such transmitters and receivers or reading devices which enter into a dialogue with the code device 9 are commercially available, so that there is no need to go into detail about them. In addition to the limit values for the clamping force, the following characteristic data can advantageously also be stored in the code devices 9 : the number and spatial arrangement (side by side and / or one behind the other) of the transport goods, the weight (individual weight and / or total weight), the dimensions (Individual dimensions and / or overall dimensions), the coefficient of friction of the transport goods 6 ff. And / or the clamp arms 5 (whereby the coefficient of friction of the transport material by the shipper and the coefficient of friction of the clamp arms are to be specified and coordinated by the manufacturer of the transport device), the strength of the Transport goods against clamping forces of the clamp arms, namely the transport goods if it is to be transported unpackaged and the packaging with the contents, if the transport goods are to be transported packed, the contents (article numbers) of the packaging, the location at the shipper, the delivery address of the The recipient, the delivery time Unkt, the limit values for the depth of entry of the goods to be transported between the clamp arms and the limit values for the clamping force. The data relating to the exchange of goods between the sender and recipient of the goods can - after printing - replace the usual shipping documents.

The vehicle 1 and / or the transport device 4 are provided with a central unit 10 , the details of which will be explained below with reference to FIG. 4. In this central unit 10 , the characteristic values required in each case can be correlated with one another by means of a computer in order to ensure reliable control of the transport device and reliable transport of the goods to be transported.

The following consideration may explain this: B. several boxes, the compressive strength of which is sufficient for individual transport, are set up in a row for a common transport, then each box is subject to the same clamping force due to the row arrangement, but may already have different friction pairings (arm / box or box / box) ). The weight and thus the mass forces during the acceleration of the stroke have quadrupled, which must also be communicated to the central unit of the computer, as well as the necessary "span" or the travel of the clamp arms 5 . This can be done either by the row of cartons being provided with a single code device 9 , which contains corresponding characteristics of the row arrangement, or by the fact that each code device contains the command to move the neighborhood to further code devices 9 to scan and correlate the sum of all characteristics in the computer.

Preferably, there are always several goods to be transported similar goods, d. that is, those of the same size, the same Weight and equal strength against clamping forces. The weakest Links in the power chain are always the points of attack of the clamp arms, if these are smaller than the areas on which they attack.

It goes without saying that all the characteristic data relating to the transport goods dated Shippers are to be provided. Regarding the maximum clamping force Usually from the shipper - if necessary in cooperation with the manufacturer Packaging - tests carried out. If applicable, is a To bring about coordination, provided the content of packaging - if necessary in Connection with packing pads or inserts - on the resilient packaging is involved. The packaging is usually cuboid shaped. This is particularly important when sending so-called "white goods", i. H. of kitchen stoves, refrigerators, dishwashers and washing machines as well as tumble dryers and also of kitchen and other furniture. The The subject of the invention is also excellently suitable for the transport of beverage crates set up in an area grid.

It also goes without saying that all of the transport device concerned  Characteristics of their manufacturers are to be provided. If applicable, too to bring about a vote here, provided that the cooperation of the Transport goods and the transport device are affected.

The interaction of code devices and transmitter / receiver or reading device is in the current state of the art - good condition provided - up to distances of 7 meters and with increasing Tendency also possible above. Transponders can also be covered, e.g. B. inside packaging, or on the side or top and back be attached to the side of the cargo, as the signal transmission here by electromagnetic waves (e.g. with radio or medium frequency). It is assumed that there is no shielding through metallic walls or close-meshed grids (Faraday cage) he follows.

Since transponders are expensive in relation to adhesive labels, it is recommended their use preferably in reusable packaging or in removable form for reuse.

Figs. 2 and 3 show by projecting the bottom clip arms 5 in a trapezoidal shape, and the voreinan to the are movable away from each other by means of linear guides 11, in Fig. 2 perpendicular to the plane and in Fig. 3 parallel thereto. The drive takes place via a hydraulic drive 12 with oppositely acting hydraulic cylinders 13 (see also FIG. 5). Such an arrangement is described in DE 44 33 050 A1, however in a different space, namely with horizontally projecting bracket arms, which is expressly included in the disclosure content of this protective right. This document also discloses the hydraulic drive which is integrated in the transport device 4 and is therefore no longer described in detail here.

The hydraulic drive can also be supplied with energy by an accumulator 14 . The clamp arms are provided with anti-slip coatings 15 on the inside. The linear guides 11 are attached to the undersides of Hohlpro files 16 , which are designed as insertion pockets for fork lifts, not shown, so that a conventional forklift can be used as a vehicle 1 .

Fig. 4 shows a side view of the front part of a vehicle 1 with a mast 2 , which is pivotable in the direction of the upper double arrow, and with a transport device 4 a for cylindrical cargo 6 e, z. B. a paper roll for printing machines. The transport device 4 a also has two clamp arms 5 and can be pivoted about an axis A by means of a rotary drive known per se. The goods to be transported 6 e are usually picked up on the vertical axis of the goods to be transported, rotated and transported with a horizontal axis and then parked again with a vertical axis or hung directly into a printing press. The vertical storage - also in columnar stacks - serves to avoid deformation under its own weight. This vehicle 1 also has a control device which is not visible here and with which a necessary but not excessive clamping force of the clamp arms can be generated in the manner already described in accordance with the data read in by a code device and / or vehicle-side data.

Fig. 5 shows in a very schematic representation of the main drive elements and the control and regulating device 18. The drive 12 includes two oppositely acting hydraulic cylinders 13 , which are controlled by control valves 17 , 19 and 20 and are supplied with hydraulic fluid by means of a hydraulic unit 21 . The control valves 17 , 18 and 20 are commercially available components, namely the control valve 17 is a hydraulically unlockable check valve and the control valve 19 is a proportionally controlled pressure relief valve as described in the company publication BOSCH "Proportional valves without / with built-in electronics", edition 1.95 , is described. The effect of these valves is based on the fact that the variable force of a proportional magnet is compared with that of a spring. The path (position) resulting from this comparison corresponds to a pressure setting or, in the case of throttle and directional control valve, a throttle cross-section and thus a volume flow. This enables a continuous or proportional control of the clamping force of the clamp arms 5 in accordance with the data processing. Part of the electrical control lines is indicated dashed lines.

A receiver 22 for querying the code device (s) 9 and a sensor 23 for determining the entry depth "T" are connected to the central unit 10 . The sensor 23 can be operated by emitting light to form light barriers or by ultrasound with reflection measurement, as described in DE 38 01 133 C2. The operation of the receiver 22 and the data processing has already been described in detail above. By means of an input device 24 , for. B. a keyboard, new data and commands can be entered who the. By means of a display device 25 , for. B. a display, all input data and the queried characteristic data can be displayed, furthermore alarm signals can also be triggered in the event of impending malfunctions due to a non-compatibility of characteristic data of the goods 6 , 6 a, 6 b, 6 c, 6 d and 6 e and the properties and / or settings of the transport device 4 and 4 a, z. B. in the event of an impending overload. Acoustic warning signals can also be generated by means of a sound generator 26 .

The critical time is in any case the time the goods are lifted from the storage area and set down on a new storage area, because in these cases the mass forces during acceleration and deceleration have to be added to the weights. There are also vertical forces due to vehicle movements over uneven floors. These factors can also be taken into account, in accordance with the design of the transport device 4 and 4 a and / or the central unit 10, with corresponding safety supplements on the basis of measured values in the associated computer. Acceleration and deceleration values, which can be traced back to vehicle movements, can be measured and evaluated using appropriate sensors on the vehicle or chassis. This allows the clamping forces to be increased and maintained in fractions of a second.

This makes it very quick to check whether taking into account the specified clamping force, the coefficient of friction, the weight, the acceleration of the lift and the movements of the vehicle can be transported safely at all.

In borderline cases it may be necessary to consider whether there is an increase in clamping force is still compatible with the strength of packaging, and whether it is it is more favorable to damage the packaging if the Transport goods to be preferred or, if necessary, reducing the driving speed like to stop the vehicle and put the load down.

Transport goods coded in this way can also be used for intermediate storage and / or at the recipient with appropriately or analogously equipped Transport devices resumed and / or further transport be animals. The invention can also be used with Greifeinrich which are also hung on a crane bridge, for example.
