Definitions
- the invention pertains to the technical field of electrically driven strapping tools. More particularly, the invention relates to an externally-powered strapping or packaging tool that includes a strapping tool subassembly powered by an external power source. BACKGROUND
- Various tools are known in the packaging art for performing numerous functions related to the manipulation of strapping, which is commonly used as a closing mechanism for securing loads in e.g. containers, and as a convenient means for easily attaching two objects to one another (e.g., attaching a box to a pallet).
- Some of these conventional tools are powered directly from a centralized system, such as a building electrical system or a central pneumatic system.
- a limited amount of strapping tools are internally provided with a power supply, whereby such supply is an integral part of the tool.
- Aforementioned types of conventional packaging tools have numerous limitations and drawbacks.
- the tools powered directly from a centralized system are not readily portable, and are rendered inoperable if the centralized system experiences an outage.
- the packaging tools containing an integral power source are more portable, they have other significant limitations and drawbacks. For example, if there is a problem with the power source in one of these tools, the entire tool is rendered inoperable until the power source is repaired or replaced. Moreover, these tools are only designed to be powered by one particular power source, and thus, do not offer the user the flexibility to interchange the power sources if desired or required. Finally, although pneumatically driven strapping tools perform well, these are often cumbersome in use, and require a significant amount of man power. Moreover, the applied force is variable and hence cannot be applied uniformly amongst different loads.
- WO 2014 008 493 describes a strapping tool that provides for an external power source which is coupled to the strapping tool. Downside of the tool as described in WO 2014 008 493 is the fact that when coupled, the strapping tool and the power source assembly are substantially immovable to each other. This restricts the use of the tool and the freedom of movement of the user. Moreover, due to its specific construction, the power supply is, once attached to the strapping tool, not readily and quickly interchangeable.
- an improved strapping device that can be alternatively powered by different external power sources.
- a strapping device that is powered by an external power source that is durable, reliable, sufficiently light, and both quick and easily interchangeable.
- a packaging tool that is powered by an external power source that is compact and properly balanced with respect to the remainder of the device.
- the device should provide a force independently from its user and from other variables.
- the device should allow a certain degree of flexibility to the user, and should allow movement of the power supply around a certain angle, in view of the strapping module.
- the present invention aims to resolve at least some of the problems mentioned above.
- the present invention provides a strapping device according to claim 1 suitable for being connected to an external power supply.
- the current invention further describes an assembly of such a device connected to the power supply according to claim 10.
- Both modules are easily engaged and disengaged by means of an adaptor module which in certain embodiments allows a certain degree of rotational flexibility of the power supply in view of the strapping and adaptor module. The latter allows a better ergonomic use in view of the existing tools on the market.
- the specific design of the adaptor module allows a flexible interchange of alternative power supplies, thereby broadening the action radius of the assembly. As such, the assembly is able to apply considerable forces, to date unknown to the current existing tools on the market.
- the assembly is easy in use and has a lightweight configuration but is yet robust and trustworthy.
- the current invention equally relates to lashing and strapping of loads by means of the assembly according to the current invention. By doing so, a high degree of uniformity is achieved as the desired force can be pre-set in advance.
