Description

[0001] The invention relates to a device for transporting goods for attachment to a lifting vehicle, in particular to a transport device of a forklift truck, according to the preamble of claim 1, and a method for manufacturing a device for transporting goods according to the preamble of claim 10.

[0002] It is known to tilt a longitudinal transport device, particularly forklifts, by means of the mast tilting mechanism of a lifting vehicle, for at least temporarily picking up the load. While a small tilt angle of close to 0° is necessary for driving onto a pallet, when transporting the load, it should be tilted as far back as possible to prevent the load from slipping off. The tilting function is therefore an important additional function for the safe transport and picking up of loads.

[0003] A disadvantage is that tilting the lifting mast results in an inaccurate adjustment that is highly dependent on the driver.

[0004] GB 2 266 700 A discloses a device for transporting goods according to the preamble of claim 1.

[0005] DE 10 2008 023531 A1 discloses a forklift truck with a lifting device comprising a lifting carriage that can be moved up and down, and with at least one fork tine equipped with a foldable load section.

[0006] The object of the present invention is to ensure simple and safe handling of transported goods by providing a tilting function.

[0007] The problem is solved by a device for transporting goods, for attachment to a lifting vehicle, with a lifting mast, in particular on a transport unit of a forklift truck, comprising a longitudinal transport means for at least temporarily receiving the goods, in particular forks, in particular two or more longitudinal transport means, a tilting means for tilting the longitudinal transport means, in particular forks, in particular two or more longitudinal transport means, comprising at least one electromechanical actuator means, in particular for linear adjustment, which acts on an attachment area of ​​the longitudinal transport means, in particular several longitudinal transport means, to tilt, wherein two electromechanical actuator means, in particular electric adjustment cylinders, are arranged parallel to each other, vertically or horizontally, in the tilting means.wherein the force effect of the electromechanical actuator means is supported on a pivot axis above the electromechanical actuator means, wherein the lifting trolley means has a support frame, wherein the at least one electromechanical actuator means, in particular an electric adjusting cylinder, is arranged at a lower end on a rocker arm element, which is tiltably arranged on a lower area of ​​the support frame and is arranged to act inclinedly on the starting area of ​​the longitudinal transport means.

[0008] The present invention provides an electrically driven, tiltable attachment, which can optionally also be equipped as a side-shift attachment and which additionally offers an advantageous tilting capability. The advantageous design reduces the obstruction and the weight. The device according to the invention provides a highly flexible device that can be adjusted to the respective transport situation, while simultaneously complying with safety regulations and being adaptable to various lifting vehicles, thereby reducing or replacing the hydraulic system. Maintenance and repairs require significantly less effort, and, moreover, no hydraulic oil is needed, which protects the environment. Furthermore, connecting the electric attachment to a forklift is simpler; in particular, it can be quickly disconnected from the forklift via a plug connection.Smaller devices such as hand pallet trucks can also be more easily equipped with special functions, as only a power supply needs to be provided.

[0009] The device according to the invention can easily move to a precise angular position according to a corresponding setting and is connected to the industrial truck, for example, via a CAN bus interface. Advantageously, the attachment can be tilted electrically by approximately +2° forward and -4° backward. The tilt angle can be set to preset values, in particular with a display of the angular position, especially on a control display in the industrial truck, whereby operation is particularly possible via preselection, especially via a touch display or manually via a joystick. The device can handle heavy loads, with the attachment having the smallest possible overhang.

[0010] Further advantages include the easier application of distance measuring systems, which ensure accurate and automatic positioning, as well as space saving and good visibility for the driver.

[0011] It is advantageous if the electromechanical actuator means has an electrodynamic working means for linear adjustment, in particular an electric motor, especially a DC motor and / or synchronous / asynchronous motor and / or linear motor and / or moving coil, in particular an electric adjusting cylinder.

[0012] The device according to the invention comprises at least one or more electromechanical actuator means, in particular electric adjustment cylinders, which is / are arranged vertically or horizontally and / or two electromechanical actuator means, in particular electric adjustment cylinders, in which tilting means are arranged parallel to each other, in particular vertically or horizontally and / or the force effect of the electromechanical actuator means in the case of a vertical arrangement is supported on a rotation axis above the electromechanical actuator means.

[0013] It is advantageous if the tilting device comprises a lifting trolley device, which is intended in particular for arrangement on a lifting mast device and / or in particular for longitudinal movement on a lifting mast device and on which at least one electromechanical actuator device is supported, in particular with an upper end of an electric cylinder on a rotary axis.

[0014] It is advantageous if the pallet truck means has a holding frame, wherein a guide contour is provided on an inside of a vertical support arm of the holding frame, wherein an adjusting wheel means is provided on a lower area of ​​the electromechanical actuator means, in particular an electric adjusting cylinder, which is guided to be supported on an inside edge of the guide contour for force transmission, in particular by means of guide rollers which are arranged to be movable in the guide contour.

[0015] The actuator means are advantageously arranged vertically, with a guide system for tilt adjustment by means of a swiveling lifting carriage means, which absorbs a large part of the forces.

[0016] The device is advantageously more sensitive and adjustable. Furthermore, pressure relief for cylinders over edges is possible. The angular position can also be read on the holding frame, even without sensors.

[0017] The device according to the invention comprises a lifting platform with a support frame, wherein at least one electromechanical actuator, in particular an electric adjusting cylinder, is arranged at a lower end on a rocker arm element, which is tiltably arranged on a lower region of the support frame and is arranged to act inclinedly on the lower attachment region of the longitudinal transport element. The device is easy to assemble and control. Position measurement and determination of the inclination are advantageously possible.

[0018] It is advantageous to have a transverse screw with a worm drive and an electric motor arranged horizontally, with a transmission mechanism to drive the tilting mechanism. For example, an electric motor can be mounted centrally on a device with longitudinal transport elements, and its rotation creates the tilting motion. No guide system for the tilting motion is required; the electric motor can handle all load forces. The device is compact, requiring only a single gear reduction, and features simple control.

[0019] It is advantageous if the longitudinal transport means is arranged on a lateral adjustment means for the longitudinal transport means in the lateral direction and the lateral adjustment means, which is in particular integrated into a lifting mast and / or attachable to the lifting truck means, can be tilted by the tilting means, so that the longitudinal transport means attached to the lateral adjustment means can also be tilted and / or the lateral adjustment means comprises an electromechanical actuator means, in particular one or more linear actuators, wherein the electromechanical actuator means is / are in particular arranged parallel to the lateral direction.

[0020] The additional side-shift function can also be electrically operated in combination, advantageously with a travel range of at least approximately + / -50 mm. The tilting system and the side-shift advantageously share a common electrical control unit powered by electricity. This unit supplies the drive with electrical energy and converts it into mechanical energy. Subsequently, the two systems, tilting and side-shift, separate and each has its own mechanical guide system. The mechanical force of the systems is transmitted to the longitudinal transport means and thus also to the load, which can now be lifted, tilted, and moved laterally.

[0021] It is advantageous if a measuring device for measuring a tilt angle of the longitudinal transport device for at least temporarily receiving the transported goods is provided, wherein in particular the measuring device comprises an integrated measuring device, in particular integrated into a control device and / or the tilting device, wherein in particular the measuring device comprises a sensor device, in particular a mechanical sensor and / or an electrical sensor and / or a hydraulic sensor, wherein the measuring device comprises a sensor device that is provided corresponding to an initial position and / or an end position of the tilt adjustment of the longitudinal transport device for at least temporarily receiving the transported goods and / or the tilting device for the tilt adjustment, and / or a control device and / or regulating device, in particular a magnetic control and / or micro PLC control.for controlling and / or regulating the tilt angle by means of a tilting device for a travel path of the electromechanical actuator, in particular the cylinder travel path of the electric cylinder, wherein, in particular with the aid of the measuring device, the angular adjustment of the tilting device is to be limited to a predetermined length via the control device and / or regulating device and the tilting device, and / or the measuring device and / or the control device and / or regulating device are housed in the lifting vehicle.
