Description

  • The invention relates to an industrial transport vehicle with a transport securing device according to claim 1.
  • Such industrial transport vehicles are used for example for in-house transport logistics. With such transport vehicles, production materials are transported, for example, in a producing operation from a delivery point to a processing point. More generally, such transport vehicles serve to transport cargo, for example, in a factory hall from one station to another station. For this purpose, the transport vehicle consists of at least a tractor and at least one trailer. Such pendants are for example from the DE 199 40 899 A1 known. The trailer is used to hold cargo, which is located on a pallet or in a grid box. The load must be secured against slipping or falling off the transport vehicle. It has been customary to make such a backup by means of straps. The attachment of the straps and the subsequent removal of the straps, however, is relatively time consuming and thus impractical for rational logistics operations.
  • From the EP 0 137 455 A2 a container trailer is known, the rollers in the loading area, with which the load is displaceable transversely to the longitudinal direction of the transport vehicle, and a transport safety device.
  • The invention is therefore an object of the invention to provide an industrial transport vehicle with a simple and quick to use transport safety device.
  • This object is solved by the invention defined in claim 1. The dependent claims indicate advantageous developments of the invention.
  • According to the invention, the transport securing device has a holding device, which is arranged laterally on at least one side of the loading surface of the transport vehicle. In the lateral arrangement may be the left or right side of the vehicle or the front or back. The mounting device is pivotable about a rotational axis from a securing position into an open position. Thus, advantageously, a rotation of the mounting device takes place about the axis of rotation. The axis of rotation can advantageously on a side edge of the vehicle body, d. H. approximately at the level of the loading area, lie. The transport locking device has at least one separate from the support means, non-pivotable locking unit for locking the support means in the securing position, namely to protect against accidental opening. Due to the fact that the locking unit is separate from the mounting device, it does not participate in the pivoting process of the mounting device, but can for example be fixed to parts of the transport vehicle, for example below the cargo bed, on the vehicle frame or other suitable parts of the vehicle. The locking unit has a spring-actuated latching mechanism which automatically engages when setting the support means in the securing position and locks the support means. This allows easy handling, especially with just one hand, when locking the mounting device.
  • According to an advantageous embodiment of the invention, the support means is pivotally connected to a lever. The lever thus makes the pivoting movement of the mounting device. In addition, the lever of the locking unit in the securing position can be fixed. As a result, a cost-effective and to be built from a few parts transport protection device is specified, which can also be retrofitted to transport vehicles, especially trailers, attached, either have no possibility of securing the cargo or less manageable security options.
  • According to an advantageous embodiment of the invention, the locking unit on a spring-actuated locking pin, which is provided on its front side with a slope. The front side in this context refers to that side of the locking pin which is intended to cooperate with the lever of the mounting device. The slope cooperates with the lever when setting the support means in the securing position such that the locking pin is moved against the spring force and automatically engages upon reaching the securing position and locks the support means.
  • The transport securing device described can be advantageously applied to any type of transport vehicle, such as in trucks for public roads or railway carriages. In particular, the invention can be advantageously used in conjunction with an industrial transport vehicle, in particular a vehicle for in-house transport logistics, as described above.
  • A development of the invention according to claim 7 has the advantage of specifying a very efficient, integrated solution concept for in-house transport logistics. For this purpose, the invention is based on an improvement of the tractor and the trailer as well as an improvement of the electrical system in both vehicle parts. The equipment of the trailer with electrically operated rollers, through which the load is displaceable transversely to the longitudinal direction of the trailer, allows easy and quick loading and unloading of the trailer without manual effort. As a result, larger loads can be moved by an operator without the aid of a forklift. The provision of electrical switches on the trailer to control the movement of the rollers has the advantage that an operator can be immediately in the vicinity of the cargo and thus can clearly see the loading and unloading. An arrangement of the switch, for example, on the tractor would have the disadvantage that the operator would have a poorer overview of the loading and unloading process. As a result of the arrangement of the electronic switches on the trailer, the loading and unloading can take place more quickly and safely.
  • The arrangement of an electrical control unit for controlling the electric motor device on the tractor has the advantage that only a central control device for a plurality of trailers is required. Compared to an arrangement of a control unit on the trailer, the arrangement on the tractor has the further advantage that the control unit is better protected against damage, especially in cases where exceptionally a load of a trailer by means of forklift takes place. Experience has shown that it sometimes comes to collisions between the forklift and the trailer, which can easily lead to damage to the sensitive electrical and electronic parts of the control unit, if it were located on the trailer.
  • Advantageously, an electrical connection is provided between the tractor and the trailer. Therein, at least one line for transmitting the switch signals from the trailer to the control unit of the tractor and at least one line for transmitting the electrical actuating signals from the control unit of the tractor to the electric motor device of the trailer is provided. By this back and forth transmission of the electrical signals, the control of the electric motor device on the trailer is made possible by means of the control unit arranged on the tractor. The line may advantageously have a plurality of individual conductors for transmitting different signals.
  • The control unit may advantageously be provided for example on a loading area of the tractor. It is also conceivable to install the control unit firmly in the tractor or grow outside of the tractor.
  • According to an advantageous development of the invention, at least one electric motor device has an electric motor and a braking and / or locking device for locking the electric motor. About this braking and / or locking device, the electric motor and thus driven by the electric motor rollers of the trailer can be determined and thus secured against undesired rotation. As a result, the load is advantageously secured in the running operation of the transport vehicle against rolling down of the trailer. The braking and / or locking device may advantageously comprise various embodiments, for example a friction brake with brake shoes, which acts on the output shaft of the electric motor, or a locking pin which is actuated when the electric motor is at a standstill. The actuation of the braking and / or locking device can be done manually, for example.
  • In an advantageous development of the invention, the braking and / or locking device can be electrically actuated by applying an electrical signal with a specified nominal voltage. The electrical operation allows more control than the manual operation. In particular, thus safety functions are possible, such as preventing unwanted unlocking of the electric motor when the trailer is not yet parked precisely before a discharge ramp. In particular, the control of the braking and / or locking device by the electrical control unit of the tractor can be done, for example, when detecting the stoppage of the tractor and receiving an enable signal by the driver of the tractor.
  • According to an advantageous development of the invention, the rated voltage of the braking and / or locking device deviates from the nominal voltage of the electric motor. In particular, the rated voltage of the brake and / or locking device may be lower than the rated voltage of the electric motor. As a result, high-performance electric motors with a high nominal voltage can advantageously be installed for the energy-intensive actuation of the rollers, in particular in the case of heavy loads. Advantageously, for example, electric motors can be used with a rated voltage in the range of 66 volts. In addition, such electric motors are robust to environmental conditions encountered in production plants. As a brake and / or locking device, for example, an electromagnet can be used for the operation, which operates with a standard rated voltage of 12 or 24 volts.
  • According to an advantageous development of the invention, the electrical control unit is configured to control the braking and / or locking device. Advantageously, the control unit is thus initially adapted to adapt the accumulator voltage available on the tractor to the nominal voltage of the electric motor and additionally to the rated voltage of the braking and / or locking device. The voltage can be adjusted by means of suitable switching regulators. The accumulator voltage of the tractor is advantageously in the range of 80 volts, so that commercial batteries for industrial trucks such as forklifts can be used.
  • According to an advantageous development of the invention, a soft-start and / or soft-braking control is provided for the at least one electric motor device. As a result, an undesirable jerky displacement of the load on the rollers can be avoided. Also, the risk of tipping a cargo with high center of gravity due to a jerky start or deceleration can be avoided. In particular, such a gentle startup also benefits the electric motor device, which is thereby spared and has a longer service life, since extreme current values during starting or braking are avoided. Advantageously, the control is provided for the soft start and the soft braking in the control unit in the tractor, for example in the electronics of the switching regulator for adjusting the battery voltage to the rated voltage of the electric motor. The soft start or the gentle braking can then be done similar to a known phase control.
  • According to an advantageous embodiment of the invention, the control unit is arranged transportable and detachable on the tractor. This has the advantage that the control unit is easily replaceable. In addition, a new tractor can be quickly equipped with a control unit. It is also conceivable to provide only a certain smaller number of control units for a vehicle fleet with a number of tractors and to allocate these to different tractors as required. As a result, the invention can be further optimized in terms of cost.
  • According to an advantageous embodiment of the invention, the trailer has an electrical connection to a downstream trailer. It is possible to control the rollers of the downstream trailer via the upstream trailer and the control unit of the tractor. As a result, the advantageous concept of the invention can be extended to a plurality of trailers. In particular, it is possible to connect to a trailer equipped according to the invention another inventively equipped trailer, without any adjustments are required.
  • According to an advantageous embodiment of the invention, at least one transport securing device for securing the load is arranged laterally on the trailer, which secures the load against movement transversely to the longitudinal direction of the trailer. In this way, a slipping or falling of the cargo can be safely avoided when driving through a curve. Such a transport lock is particularly useful in addition to the braking and / or locking device when the load is transported on Euro pallets newer type, which are made of aluminum. Such aluminum pallets have a relatively low friction on the rollers usually made of metal, especially if additional moisture is present. By the additional lateral transport locking device such slipping or falling of the cargo can be avoided in an easy to implement manner.
  • According to an advantageous development of the invention, the transport securing device is pivotable from a securing position into an open position. In the securing position, the load is secured. In the open position, the load is discharged laterally from the trailer by a rotational movement of the rollers or loadable onto the trailer. Advantageously, it is further provided that the transport locking device is secured at least in the securing position by a locking unit against unintentional opening. As a result, the reliability of the transport vehicle can be further increased.
