- An inventory control system may be useful when it is important to monitor the usage of hand tools, and to ensure that they are returned to storage after use.

Abstract
An inventory control system for monitoring the removal and replacement of tools includes a container (2) having a plurality of tool storage locations in the form of recesses (10). Each recess (10) is individually-shaped to receive a specific tool, the shape of the recess being matched to the shape of the tool. A plurality of sensors (12) are provided for sensing the presence of tools in the recesses (10), each sensor being located adjacent a recesses. A data processor (16) receives signals from the sensing means and monitors the removal and replacement of tools, and an output device (14) indicates the presence and/or absence of tools in the container.
Description
- The present invention relates to an inventory control system and in particular, but not exclusively, to an inventory control system for monitoring the use of hand tools. The invention also relates to a storage container for use with the inventory control system, and an inventory control process.
- An inventory control system may be useful when it is important to monitor the usage of hand tools, and to ensure that they are returned to storage after use. This can help to ensure that tools are not lost or stolen. Such a system is particularly important when tools are used for repairing or maintaining aircraft engines, as any tools left inside the engine after completion of the job could cause catastrophic damage. Similarly, in the case of surgical tools, it is essential to ensure that no tools are left inside a patient after an operation.
- An inventory control system can also be useful by helping to ensure that only the correct tools are used for a particular task. Such a system may also be helpful to track the identity of the person using the tools, so that if a tool goes missing or if a tool is taken that is inappropriate for the task in hand, appropriate remedial action can be taken.
- One method of monitoring the use of tools is to store the tools in a container having designated storage compartments for specific tools. For example, the container may be a tool box having drawers with rigid foam liners, with cut-outs matching the size and shape of the tools. Using such a container, it is a relatively simple matter for a supervisor to check that all the tools are present by looking at each drawer in turn, to ensure that all the spaces are filled. However, this is time-consuming and laborious, and it does not allow use of the tools to be monitored on a continuous or real-time basis. In addition, the correct choice of tools for a specific task cannot easily be monitored, and the identity of the user is not automatically recorded.
- U.S. Pat. No. 5,608,193 describes an alternative tool inventory control system, in which a tool box containing tools is weighed before and after use. Discrepancies between the two weights are noted and optionally a database of tool weights can be interrogated to suggest which tool may have been left behind. The system does not however allow the presence of each individual tool to be verified or the choice of tools taken for a particular task to be monitored.
- It is an object of the present invention to provide an inventory control system and process, which mitigates at least some of the aforesaid disadvantages.
- According to the present invention there is provided an inventory control system for monitoring the removal and replacement of tools, the system including a container having a plurality of tool storage locations, each tool storage location comprising an individually-shaped recess for receiving a specific tool, the shape of the recess being matched to the shape of the tool, sensing means including a plurality of sensors for sensing the presence of tools in the tool storage locations, each sensor being located adjacent a recess for sensing the presence of a tool in the recess, a data processing device constructed and arranged to receive signals from the sensing means and monitor the removal and replacement of tools, and an output device for indicating the presence and/or absence of tools in the container.

Using this information, it is a simple matter for a supervisor to check whether all the tools are present in the cabinet and, if any are missing, who has taken them and when. The supervisor can also check that the tools taken for a particular task are appropriate for that task. Checks can be carried out by the supervisor whenever required, or they can be instigated automatically, for example whenever the cabinet is opened or at predetermined intervals. In addition, the tool cabinet can be checked visually at regular intervals, to ensure that the full complement of tools is present and that the automatic system is operating correctly.
- The computer can also keep a continuous log of how long each tool has been in use, which may be useful for tools and measuring instruments such as torque wrenches that have to be recalibrated at preset intervals. It can also be programmed to disregard the absence of tools that have been removed deliberately for repair or replacement.
- It may be noted that although the system checks for the presence of a tool in each of the sensed recesses, it does not check that the correct tool has been placed in each recess. In fact, since in the embodiment described above the detectors are simple magnetic detectors, it would be relatively easy to mislead the detection system, for example by placing a steel bolt in one of the recesses instead of the correct tool. This is not considered to be a serious disadvantage, since the main aim of the system is to ensure that trusted personnel do not accidentally forget to return tools to the container after use, rather than preventing deliberate theft. However, it is worth noting that since the system also records who has taken each tool from the container, this will deter deliberate theft, particularly if regular visual inspections of the cabinet are also carried out.
- If necessary, the system can be adapted to include more sophisticated sensors that are capable of detecting the presence of individual tools, for example by detecting identification tags attached to the tools. However, this is generally less preferred, since it increases the cost and complexity of the system and gives rise to other disadvantages, such as the difficulty of attaching tags to the tools and the risk of the tags becoming detached during use. The simple system described first is likely therefore to be preferred in many situations.
- Various other modifications of the invention are of course possible. For example, instead of using magnetic sensors to detect the presence of tools in each of the recesses, other types of sensor such as optical sensors or mechanical switches may be used. Alternatively, instead of providing a separate sensor for each recess, the cabinet may include an array of optical sensors mounted above each drawer, which scan the drawer as it is opened, in a manner similar to a conventional optical scanner. An image of the drawer can then be generated, which can be compared with previous images to sense the removal of tools from the recesses or their replacement in the recesses. Alternatively, instead of optical sensors, an array of magnetic sensors can be used to scan the drawer as it is opened.
- The tool container may also take different forms: for example it may consist of a box with a single layer of tools, or with tools in removable trays, or it may take the form of a cupboard or a board on or within which the tools are hung, or any other suitable form. The tools may also of course be of any kind, including engineering tools, surgical tools and so on. The invention may also be adapted to other non-tool applications where an inventory control system is required, and references within this specification to tools should be construed accordingly to include equivalent items in suitable non-tool applications. The invention may for example be used for inventory taking or stock taking/control purposes.
