Description

[0001] Title: Handle fitting system

[0002] The invention relates to a handle fitting system comprising a handle fitting apparatus and multiple interchangeable modules, and to a method for fitting handles to pails using such a handle fitting system.

[0003] Handle fitting apparatuses are used for providing pails with a handle. Typically, these handle fitting apparatuses are set up adjacent an injection moulding apparatus for producing pails. The pails are fed from the injection moulding apparatus to the handle fitting apparatus to provide the just made pail with a handle.

[0004] The handle fitting apparatus comprises a pail transport device for transporting pails from a receiving station, via a fitting station, to a stacking station. At the receiving station, the injection moulded pails are fed into the fitting apparatus, at the fitting station a handle is mounted to the pail, and at the stacking station the pails, provided with a handle, are stacked by a stacking device.

[0005] Handle fitting apparatuses are typically configured to fit a specific type of handles. There are handle fitting apparatuses configured for fitting a plastic handle to a pail, and there are handle fitting apparatuses configured for fitting a metal handle to a pail.

[0006] Mostly, the handle fitting apparatuses are configured to perform one or more manufacturing steps, before the handle is ready to be fitted on the pail. However, there are also apparatuses configured to fitting premade handles to a pail.

[0007] For example, plastic handles can be provided as a series of strips that are to be bent while being mounted to the pail. In such an fitting apparatus, the plastic strips are separated from each other and are individually transferred to a fitting device. The fitting device engages the strip to bent the strip into the shape of the handle, and to subsequently mount the handle to the pail.

[0008] Metal handles are typically made from wire. Typically, metal handles are not provided in a buffer of premade handles, but are provided in the form of metal wires that are formed by a forming device just prior to being mounted to the pail. In yet another handle fitting apparatus, the apparatus comprises a buffer for holding premade handles, which are individually presented to the fitting tooling to be mounted on a pail.

[0009] Typically, injection moulding apparatuses for manufacturing pails are set up in rows, one next to the other, along a granulate providing street / transporter configured to transport granulate to each of the injection moulding apparatuses. Adjacent each injection moulding apparatus a handle fitting apparatus is set up, for receiving pails from the injection moulding apparatus, and for providing those pails with handles. Because the space between two injection moulding apparatuses is limited, each injection moulding apparatus is provided with one handle fitting apparatus only.

[0010] Due to each injection moulding apparatus being provided with a single handle fitting apparatus, the pails delivered by the specific injection moulding apparatus are either provided with plastic handles or with metal handles, depending on the type of handle fitting apparatus.

[0011] Even though a metal handle fitting apparatus can be replaced with a plastic handle fitting apparatus, or vice versa, in practice this is not, or only seldom, done. Also, providing an injection moulding apparatus with two handle fitting apparatuses, e.g. one for fitting plastic handles and one for fitting metal handles, is often not an option due to the limited space available between two injection moulding apparatuses.

[0012] Because of the large batches of pails that are produced, it is often not a problem that the handle fitting apparatuses can only fit a single type of handle to the bails. For example, if the production of pails with a plastic handles needs to be increased, the injection moulding apparatus provided with a plastic handle fitting apparatus are used to run extra batches of pails.

[0013] It is an object of the invention to provide an improved handle fitting apparatus. It is a further object of the invention to provide a handle fitting apparatus that enables a more flexible production process, more in particular that allows for providing the pails of an injection moulding apparatus to be provided with different types of handles, preferably within the space typically available between two injection moulding apparatuses. It is a further object of the invention to provide a handle fitting apparatus that can fit different types of handles to pails, wherein the footprint of the handle fitting apparatus is at most similar to, preferably is smaller than, the footprint of a plastic handle fitting apparatus or a metal handle fitting apparatus. SUMMARY OF THE INVENTION

[0014] According to the present invention, this object is achieved by a handle fitting system according to claim 1.

[0015] A handle fitting system according to the invention comprises a handle fitting apparatus and multiple interchangeable handle modules. According to the invention, the handle fitting apparatus comprises a docking station for docking one of the interchangeable handle modules, and the handle modules are configured to, when docked in the docking station, present a specific type of handles in a handle transfer location to the handle fitting device

[0016] By thus combining the fitting apparatus with different modules, the fitting apparatus can be adapted to fit a specific type of handles, i.e. the type of handles presented by the module docked in the docking station, to a pail. To change the type of handles to be fitted to the pail, the module is replaced with a module that is configured to present the fitting device of the apparatus with the desired type of handles. Thus, it is no longer necessary to replace and install the handle fitting apparatus. Only the module needs to be changed. This saves time and money, and allows for a more flexible production process.

[0017] The handle fitting apparatus of a handle fitting system according to the invention is configured to be used with each of two or more handle modules, which allows for the fitting apparatus to mount two or more types of handles on a pails. The invention thus provides an improved handle fitting apparatus

[0019] - a pail transport device, for transporting a pail from a pail receiving station to a pail fitting station, and for transporting the pail provided with a handle from the pail fitting station to a pail stacking station;

[0020] - a pail orientation device, located at the pail fitting station, for supporting a pail in a fitting position for fitting a handle to the pail;

[0021] - a handle fitting device, located at the pail fitting station for in a handle fitting location fitting a handle to a pail supported in the fitting position;

[0022] - preferably a pail stacking device, located at a pail stacking station, wherein the pail stacking device is configured for stacking pails that are provided with handles; and - a module docking station for exchangeable docking one interchangeable module; wherein the handle fitting system further comprises at least two of the three below mentioned interchangeable modules, which modules are each configured to be docked in the docking station, and are configured to, when docked in the docking station, present a specific type of handles in a handle transfer location to the handle fitting device;

[0023] - a plastic handle manufacturing module for manufacturing plastic handles out of plastic strips, and for presenting the plastic handles one by one in the handle transfer location, when the plastic handle manufacturing module is docked in the docking station;

[0024] - a metal handle manufacturing module for manufacturing metal handles out of metal wires, and for presenting the metal handles one by one in the handle transfer location, when the metal handle manufacturing module is docked in the docking station;

[0025] - a handle buffer module for holding premade handles, e.g. injection moulded plastic handles, and for presenting the premade handles one by one in the handle transfer location, when the handle buffer module is docked in the docking station; wherein the handle fitting device comprises a handle gripper for engaging a handle presented in the handle transfer location by one of the at least two modules that is docked in the docking station, and for fitting the handle in a handle fitting location to a pail supported in the fitting position, and wherein the apparatus comprises a module control system that is configured to control each of the at least two interchangeable modules when docked in the docking station.

[0026] According to the invention, each of the at least two interchangeable handle manufacturing modules is configured to present a specific type of handle to a universal handle fitting device. By mounting for example the metal handle manufacturing module in the docking station, the handle fitting apparatus is equipped for fitting metal handles to a pail. By replacing the metal handle manufacturing module with a plastic handle manufacturing module, the handle fitting apparatus is equipped for fitting plastic handles to a pail.

[0027] Thus, a handle fitting apparatus according to the invention is a multiple configuration apparatus. The apparatus can be set up for in a first configuration for fitting plastic handles to pails and can be set up in a second configuration for fitting metal handles to pails, while those pails are supported in the fitting position by the pail orientation device.

[0028] To allow for the different modules to work with the same handle fitting device, according to the invention the modules are configured to present the handles in a handle transfer location that is within reach of the handle fitting device, more in particular that is in reach of a gripper of the handle fitting device that is configured for mounting handles on a pail. Therefore, the modules do not each comprise a pail fitting device.

[0029] In an embodiment, the handle modules of the handle fitting system each comprise a similar outer frame, wherein the outer frame is configured to be coupled with, for example to be supported by supports of, a frame of the fitting apparatus. In such an embodiment, the outer frame of the handle modules forms an extension of the frame of the handle fitting apparatus when the module is docked in the docking station.

[0030] It is noted that in the prior art, for some types of handle fitting apparatuses, the fitting device typically is an integral part of the handle manufacturing device. In such an embodiment, the fitting device performs one or more fabrication steps, e.g. bending of plastic strips or metal wires. This is not the case with a handle fitting system according to the invention. In a handle fitting system according to the invention, the manufacturing and / or the processing of handles is done in the respective modules, while the fitting device of the fitting apparatus is used only for mounting the handle to the pail. Therefore, the fitting apparatus according to the invention is provided with a universal fitting device, i.e. the fitting device can be used with different types of handles, which allows for the fitting apparatus to be used with interchangeable modules.

[0031] When one of the at least two interchangeable modules is docked in the docking station, the module temporarily is an integrated component of the apparatus. This allows for the module control system, mounted in the apparatus, to control the module and thus for the handle fitting system to provide a batch of pails with a specific type of handle presented or manufactured by the module docked in the docking station.

[0032] In an embodiment, the apparatus comprises a main control system for controlling the pail transport device, the pail orientation device, the pail stacking device and the handle fitting device, and the main control system comprises the module control system. Thus, the apparatus comprises a single control system that not only controls the components of the apparatus, but also the exchangeable module that is docked in the docking station. This allows for the quick exchange of modules, because after the module is docked in the docking station there is no need for a control system of the module to exchange information with the main control system that controls the other components of the apparatus, since the control systems are already integrated in the main control system.

[0033] In an embodiment, the docking station is provided with at least one control quick connector that is connected to the module control system and the at least two modules are each provided with at least one control quick connector for connecting the module, via the at least one control quick connector of the docking station, to the module control system.

Thus, the handle fitting system is provided with a shared power source instead of providing each module with its own power source. This is in particular beneficial because the apparatus is also provided with a shared module control system, because this allows for optimal integration of the module control system and the power source.

[0036] In a further embodiment, the docking station is provided with at least one power quick connector that is connected to the power source of the fitting apparatus and the at least two modules are each provided with at least one power quick connector for connecting the module, via the at least one power quick connector of the docking station, to the power source of the fitting apparatus. In such an embodiment, each module is preferably provided with its own a power distribution device, which power distribution device is controlled by the shared control system mounted in the handle fitting apparatus.

[0037] In an embodiment, the at least two modules are each provided with module identification device, for example a RFID device or a blue tooth device or an optical identification device such as QR-code to be identified by an optical sensor on the handle fitting apparatus, that is configured to signal the module control system what type of handles the module manufactures, when the module is docked in the docking station. Thus, in such an embodiment, the module is configured to signal the module control system which what type of module is docked in the docking station, such that the module control system knows which sub routine is to be used to control that module. In an alternative embodiment, the apparatus, more in particular the module control system that is mounted in the apparatus, may be provided with an input device, e.g. a keypad or handle, that allows for an operator to signal the control system what kind of module is docked in the docking station.
