Description

This invention relates to button shank feed apparatus for use with button shank wrapping apparatus and to a method of use thereof.
In order to secure a button to a garment, material or fabric, it is known to pass thread through holes in the button and through the garment, material or fabric a number of times. The accumulated thread between the button and garment/material/fabric forms the button shank, which is then finished off by winding thread around the shank so as to wrap it or whip it. The wrapped thread can then be bonded in place on the button shank by heat fusing or applying a bonding agent. This process can be undertaken manually, or more commonly is undertaken by a button shank wrapping machine.
An example of a button shank wrapping machine is disclosed in WO98/09012 , the entire content of which is incorporated herein by reference. The machine comprises a whipping plate having a slot for receiving the shank of a single button attached to a garment in use. The whipping plate is typically domed in shape to ensure the whipping thread is unobstructed when being wound around the shank during the wrapping process. On initiation of the thread wrapping or whipping process, thread is unwound from a thread cone located in the machine and wound around the button shank under tension. A heated fork then moves into contact with the wrapped shank and is held in place for a time sufficient to bond the wrapped thread to the shank. The thread located between the thread cone and the heat sealed button shank is cut or broken adjacent the shank. A user then lifts the wrapped and heated shank and button from the whipping plate slot.
A problem with this type of button shank wrapping machine is that it requires a worker to manually insert and remove each button shank from the machine. In addition, the machine can only receive and process a single button shank at any one time. Since a garment is likely to have a number of buttons on the same, this makes the process of button shank wrapping for a garment labour intensive and time consuming.
It is therefore an aim of the present invention to provide button shank feed apparatus for button shank wrapping apparatus that overcomes the abovementioned problem.
It is a further aim of the present invention to provide a method of using button shank feed apparatus for button shank wrapping apparatus that overcomes the abovementioned problem.
It is a yet further aim of the present invention to provide button shank wrapping apparatus including button shank feed apparatus.

Embodiments of the present invention will now be described with reference to the following figures, wherein:

Figures 1a-1e show a front perspective view, a front view, a side view, a rear view, and a top plan view of button shank wrapping apparatus including button shank feed apparatus according to an embodiment of the present invention respectively;
Figure 2 is a front perspective view of the button shank wrapping apparatus in figures 1a-1e with part of the front cover of the apparatus removed;
Figure 3 is a front perspective view of the button shank wrapping apparatus in figure 2 with part of the movement means of the apparatus removed;
Figure 4 shows a perspective view of button shank wrapping apparatus according to a further embodiment of the present invention.

Referring to the figures 1a-3, there is illustrated button shank wrapping apparatus 2 including button shank feed apparatus 4. In accordance with the present invention the apparatus allows automation or semi-automation of a button wrapping process and allows multiple button shanks to be located in the apparatus at any one time. It is to be noted that the apparatus also works if only a single button shank is used in the apparatus at any one time.
The part of the apparatus that undertakes the button shank wrapping process can be integrally formed with the part of the apparatus that undertakes feeding of the button shank through the apparatus in use, or can be attached to or in relative proximity to the same.
Button shank wrapping apparatus 2 is for the wrapping or whipping of a button shank. Any type of button shank wrapping apparatus can be incorporated into the present invention, such as for example of a type disclosed in WO98/09612 , the content of which is incorporated herein by reference. In the illustrated example, it comprises a housing portion 6 having a top wall 8, a base wall 10, two side walls 12, 14, a front wall 16 and a rear wall 18.
A thread reel support 20 is provided on a bracket 22 protruding outwardly from rear wall 18 for supporting a reel of thread used for the shank wrapping in use. A thread tensioning arm 24 is provided on rear wall 18 to tension the thread coming from a thread reel located on reel support 20 in use. An entry aperture 26 is defined in top wall 8 to allow the wrapping thread to enter the housing portion 6 in use.
An electrical connection port 28 is defined on rear wall 18 to allow an electrical power cable to be connected to the same for an electrical power supply to the apparatus in use.
A counter display 30 is provided on top wall 8 to allow a user to see how many shank wrappings are to be provided for each button shank in use.
The walls 8, 10, 12, 14, 16, 18 can each be independently removed to allow access to the interior of the housing portion 6. The walls are secured to an internal housing frame via a plurality of fixing screws 32.
The button shank feed apparatus 4 comprises a housing portion 34 which is upstanding and protrudes outwardly of top wall 8 adjacent front wall 16 of housing portion 6.
The feed housing portion 34 comprises a top wall 36, rear walls 38, side walls 40, 42 and a front wall 44.
The housing portion 34 acts as a support means for one, and preferably a plurality, of button shanks in use. In particular, an elongate slot 46 is defined in front wall 44 and has an input aperture 48 defined in top wall 36 and an outlet aperture 50 defined at an opposite end thereof.
Adjustment means can be provided on or associated with housing portion 34 to allow adjustment of the apparatus to accommodate different sized buttons in use if required. The adjustment means in one example could include one or more plate members that are movable relative to slot 46.
Clearance or mechanical means can be provided to allow any button or button shank that may become stuck in slot 46 to be released. For example, the clearance or mechanical means could include one or more movable arms that can be automatically or manually moved relative to slot 46 to move items contained in the same. In one example, a switch associated with slot 46 counts the number of buttons/button shanks located in the slot 46. If less buttons/button shanks are detected by the initiation means of the apparatus, the apparatus can determine that one or more buttons/button shanks have become stuck in the slot and can activate the movable arm along slot 46 to move any stuck buttons/button shanks along the slot.
Micro-processing means can be provided in the apparatus to allow control of one or more functions of the apparatus, such as for example associating the switch count with actuation of the clearance or mechanical means in use.
The housing portion 34 is arranged such that a button attached to a garment by thread to form a shank can be inserted into input aperture 48. The shank passes through the slot 46 and the garment is adjacent the front wall 44 of the housing portion 34.
Movement means in the form of a rotatably mounted disc member or whipping plate 52 is provided adjacent the output aperture 50 at the base of the housing portion 34. Receiving means in the form of four slots 54, 56, 58, 60 are defined at 90 degree intervals around the peripheral edge 62 of disc member 52. Each receiving means 54-60 is for receiving a button shank in use.
It is to be noted that in the illustrated example the disc member 52 is flat and planar on its front and rear surfaces to allow unhindered rotation of the same between the different locations within the apparatus.
The disc member 52 can be rotatably mounted on a drive shaft connected to a drive mechanism, such as a motor. The motor can be powered by the electrical power supply when connected to apparatus 2 in use. Alternatively, the disc member 52 is connected to a pneumatic rotational feed 64, which is powered by compressed air.
A plurality of windows 66 are defined in disc member 52 which allow part of movable clamping means in the form of a hook 68 to pass at least partially therethrough in use. The hook 68 stretches the button with respect to the garment so that the button shank is unobstructed for the shank wrapping process, as will be explained in more detail below.
Initiation means including an initiation arm member 70 are provided adjacent the base of a receiving slot 54 when located adjacent output aperture 50 of the housing portion 34. The initiation arm member 70 is pivotally mounted via pivot pin 72 and is movable between a resting position, as shown in figures 1a-1e, and an operational position. The initiation arm member 70 is resiliently biased via resiliently biasing means, such as a spring, to the resting position.
In the resting position, a free end 74 of arm member 70 is in a relatively raised position with respect to outlet aperture 50 and slot 54. When a button shank is received in slot 54, the shank contacts the free end 74 of arm member 70 causing the same to pivot downwardly to the operational position. Thus, the initiation means can detect when a button shank is located in the support means in a button shank support location and initiate rotation of the disc member 52. Rotation of the disc member 52 moves the slot 54 and the button shank located therein in use from the button shank support location (typically shown as a 12 o'clock position or 0 degree position), through 90 degrees to a button shank wrapping location (typically shown as a 3 o'clock position or 90 degree position).
With a button shank located in the button shank wrapping location, a button shank wrapping process can take place. A number of different and largely conventional processes can be employed to wrap the button shank at this location. However, some of the main components of the button shank wrapping process in the apparatus shown in figures 2 and 3 include a thread tube 76 which allows the wrapping thread to be delivered to a location at or adjacent the button shank wrapping location. Clamping hook 68 and a further clamping hook 78 are provided to clamp the shank wrapping thread in use. Pneumatic cylinders 80, 82 are provided to actuate movement of the clamping hooks 68 and 78 respectively between open and closed positions to allow unclamping and clamping of the wrapping thread respectively. A pneumatic cylinder 79 is also provided to allow the clamping hooks 68, 78 to be moved between raised and lowered positions respectively to allow wrapping of the shank. The clamping hooks 68, 78 are pivotally mounted at pivot points 81 to allow the clamping hooks to be moved towards the disc member 52 or forwardly of the apparatus at the start of the button shank wrapping process to ensure the position of the thread clamping hooks and therefore the thread is in the correct location with respect to the disc member 52, and away from the disc member 52 or rearwardly of the apparatus at the end of the button shank wrapping process. Pneumatic cylinders are provided in the apparatus to drive pivotal movement of the clamping hooks 68, 78 between the forwardly and rearwardly positions. A heated fork 84 is provided to allow the wrapped thread to be heat bonded to the button shank in use. A pneumatic cylinder 86 is provided to allow the heated fork 84 to be moved into and out of contact with the button shank.
Once the wrapped shank has been heated by fork 84, fork 84 is moved clear of the wrapped and heat shank and the disc member 52 and the slot 54 is moved from the button shank wrapping location (provided at the 90 degree position) through a further 90 degree position (typically to a 6 o'clock position or a 180 degree position) to a button shank release position.
In the button shank release position, the slot 54 is adjacent feeder apparatus outlet means in the form of a slot 88 defined between two outlet arms 90, 92. The button shank contained in slot 54 in the release position falls under gravity from slot 54 and through slot 88. A section 94 of the front wall 16 has a tapered recess 96 to allow the button and button shank to be smoothly dispensed from the feeder apparatus 4.
Since the above described process is arranged to take place automatically following actuation of the initiation arm member by contact of a button shank with the same in use, it will be appreciated that once a button shank is initially loaded into the slot 46, the apparatus can be left to wrap and heat the shank and dispense the shank automatically without any further user intervention being required. This significantly saves on user input and time. In addition, since the slot 46 is elongate in form, a number of button shanks attached to one or a plurality of garments or fabrics can be loaded into slot 46 of the apparatus before or during operation of the apparatus 2 to form a stack. Each button shank in the stack is then processed through the wrapping apparatus in turn.
The apparatus 2 can have a number of button shanks located in receiving slots 54, 56, 58 at any one time (i.e. simultaneously), thereby allowing initiation of a button shank wrapping process, a button shank wrapping process, and dispensing of a wrapped button shank to take place simultaneously, almost simultaneously or in rapid succession.
In order to load the button shank feeder apparatus 4, a plurality of buttons are loaded into aperture 48 of the feeder apparatus 4 such that the button is in the interior of the apparatus, the shank is located through the shank and the garment, material or fabric to which the button is attached to is located externally of the apparatus 4.
On initiation of the apparatus 4 as a result of the initiation arm member 70 being moved from the resting position to an operational position, thread contained on a reel located on reel support 20 is fed into the apparatus through opening 26, through thread tube 76 and between open clamping hooks 68, 78. The clamping hooks 68, 78 are then closed and the thread is wrapped around a button shank located in the button shank wrapping location as a result of the hooks 68, 78 moving up and down. Once the shank has been wrapped, heated fork 84 is moved into contact with the wrapped shank and heat bonds the wrapped thread to the shank. The heated form 84 is then moved out of contact with the bonded and wrapped shank. The heated and wrapped shank is then moved to a release position to allow release of the button and shank from the outlet slot 88 of the apparatus.
Referring to figure 4, there is illustrated an example of a further button shank wrapping apparatus 102 including button shank feed apparatus. In this embodiment the feed housing portion 34 is a much smaller and simpler version than that shown in figures 1a-3. It may operate with a single button shank only, or it may operate with a plurality of button shanks associated with the apparatus at any one time. The feed housing portion 34 can optionally be provided with a clearance mechanism and/or an adjustment mechanism to accommodate different sized buttons or it can be supplied without the same.
In one embodiment the housing portion 34 is interchangeable or modular to allow different types of feed housings to be provided with the apparatus in use.
