Abstract
Description
- The device and the method according to the present invention belong to the field of beader machines and the like.
- The operation of joining the corners of a door-or window-frame, made of metal or using mixed materials, within industrial type production, takes place with operations known as caulking.
- The operations described above are performed by dedicated machines, known as beader machines, constituted essentially by a fixed seat (provided with the relative runners, clamps, etc.), on which the section bars to be caulked are positioned, and by two mobile units (known as "thrust mass units" or caulk heads) to which the knife/knives or punches that perform caulking are applied.
- The loading of these beader machines is performed by one or more operators having the task of maintaining the section bars composing the frame in the correct mutual position and of placing the frame on the machine in order to perform the subsequent caulking. It is evident that these manual operations entail risks for the operator who must perform them and they present a certain degree of risk due to the incidence of human error and a certain degree of difficulty due to the fact that the frame to be machined presents a considerable degree of instability being composed of four separate metal section bars, connected to one another only by four corner joints inserted in the recesses of the profiles - at the four vertexes of the frame - without any fastening.
- The scope of the present invention overcomes these drawbacks by introducing a method and a device for the automatic loading of said beader machines.
- A method and device for the automatic feeding of beader machines and the like is described.
-
- Fig. 1 Overview of the device according to the present invention
- Fig. 2 View of the centring unit of the device according to the present invention
- Fig. 3 View of the grasping unit of the device according to the present invention
- With reference to the attached drawings, the device according to the present invention comprises four separate sections, corresponding to the various steps of the method representing a further scope of the present invention. It is possible to distinguish, in order: a
loading unit 10, acentring unit 20, a gripping andmanoeuvring unit 30 and anunloading unit 50. - The
loading unit 10, shown in greater detail in Fig. 1, is composed of across member 13 on which there are twosupports transport unit 16 comprising twobelts - The
centring unit 20, illustrated in Fig. 2, comprises twoledges sliders bar 23. Saidbar 23 rests on twosliders runners motor 210 and themanoeuvre screw 211 displace thebar 23. The right-hand 213 and the left-hand screw 214, connected to themotor 212, move the twosliders - With reference to Fig. 3, we see the gripping and
manoeuvring unit 30 or "spider" unit, responsible for picking up the frame from its position on the loading unit. - Said gripping and manoeuvring unit is supported by columns and cross members associated to the
runners trolley 316 and comprises four fixed support means 31, 32, 33, 34 connected to acentral unit 39 associated tomanoeuvring means 310, 3232 suited to transmitting to said central unit a rotary and a raising and lowering translatory motion with respect to the loading unit. Said central unit is also connected to thetrolley 311 which can slide with its own sliding elements along therunners runners trolley 316 that, in turn, is free to slide alongrunners - Said
trolleys - Said gripping and manoeuvring
unit 30 further comprises fourmobile elements mobile elements supports activation devices - Each of the aforesaid mobile elements is provided with a
slider 324 provided with suitable frame grasping means 325, 326, in turn provided withstroke plates 328, preferably clad in non-slip material such as rubber and the like so as to facilitate and make more certain the adhesion to the frame. - Furthermore, each pair of sliders on the same axis is provided with suitable manoeuvring means in order to place in the right position the sliders and the relative grasping means 325, 326. For example, said manoeuvring means may be constituted by
electric motors - In a preferred embodiment of the present invention, the
grasping element 326 is constituted by a pneumatic cylinder activating an element connected to arubber pad 329. During normal functioning, the gripping of the frame takes place in the following way, said grasping means 325 pull the four plates 328 - that in turn carry the elements 326 - against the frame whilst theother grasping elements 326 prevent during the clamping of the frame by means of the aforesaid fourplates 328, that the section bar parts composing the frame rotate being subject to a gripping force not centred around the midline axis of the section bar. Saidelements 326 act so as to grasp the section bar in further points with respect to the points of action of the grasping means 325 and therefore make it possible to prevent any undesired rotation of the individual parts of the frame section bars. - In a preferred embodiment of the present invention, said grasping means 325 and 326 are in total four each.
- Once frame gripping has been performed, the gripping and
manoeuvring unit 30 raises and transports the frame to the work position of the machine for joining thecorners 60 by means of the system ofactuators trolleys actuators - With reference to Fig. 1, the
unloading unit 50 comprises twoforks trolley 53 that with its own sliding means travels along therunners trolley 53 by themotor 56 by means of, for example, a belt-driven kinematic mechanism. - The operation of placing relative to the device according to the present invention, i.e. the set of preliminary operations that must be performed before being able to operate said device, consists in the following steps:
- h) positioning of the
supports - i) positioning of the
pawls supports manoeuvring unit 30 or spider - j) positioning of the
mobile elements sliders 324 depending on the length and width dimensions of the frame to be machined; - With regard to the functioning of the device according to the present invention as described previously, the method for the automatic feeding of beader machines according to the present invention is performed through the following sequence of steps:
- a) Placing of the automatic feeding device. This operation is performed according to the three steps h) - j) described previously
- b) Introduction of the frame in the loading station. The frame is composed of four metal section bars and four joints. The joints are inserted into the recesses of the section bars without any fastening, so the frame presents a considerable degree of instability. The introduction of the frame into the load station is an operation performed by a mechanical system or by an operator before the automatic positioning system is started.
- c) Starting, by the operator, of the automatic positioning system.
- d) Transport of the frame from the loading to the grasping area. The transport is performed with particular care in order to avoid the frame being scratched. The frame reaches the grasping area with the corners closed, with the sides orthogonal to one another and with the external perimeter of the frame centred with respect to the gripping mechanism
- e) Frame grasping and positioning of the four corners of the frame on the joining machine. The gripping mechanism grasps the frame in such a way as to keep the corners perfectly matching during the operations of positioning on the joining machine. The gripping mechanism performs the movements and the rotations necessary to position the four corners on the joining machine
- f) Corner junction operation. This operation is performed by the joining machine tool connected to the automatic feeding system according to the present invention. The joining operation is completed after a corner of the frame has been positioned in the machine work point. At the end of the operation, the frame is taken by the grasping and positioning system to an suitable area where 90° rotation is performed, without possibility of collisions. At the end of this rotation, a new corner to be machined is positioned in the work point of the corner-joining machine. This is repeated until the joining of the fourth corner
- g) Unloading of the finished frame. This is the operation that makes it possible to transport the finished frame from the work area to an area where the frame joined at the corners is picked up.
- k) The
bar 13 moves forward pushing the frame against thepawls - I) A stopswitch sensor positioned on the line connecting the
pawls bar 13 and gives consent to the grasping system to descend - m) A stopswitch sensor detects the lowering and allows the activation of the
grasping elements 325 that tighten theplates 328 against the frame. Twoelements 325 positioned on two adjacent frame sides are activated first, then the other two. This makes it possible to obtain orthogonality. - n) Once the last stopswitch of the four
cylinders 325 has been activated, the fourgrasping elements 326 are activated. - o) The activation of all the stopswitches of the grasping means 326 allows the grasping spider to ascend.
- p) The ascent stopswitch allows the activation of the movement system of the
trolleys manoeuvring unit 30 closer to thebeader machine 60. - q) The advancing of the trolleys is decelerated when suitable photoelectric sensors detect that the trolley has come into the vicinity of the
beader machine 60. - r) Positioning is complete when the frame rests against the
ledges - s) Two proximity sensors positioned on these ledges allow the machine to start the corner caulking cycle
- t) Once the caulking cycle is finished, the beader machine gives consent to the grasping spider to retreat to a safe area for the 90° rotation.
- u) Once the 90° rotation is finished, a sensor makes it possible to take the corner back to the beader machine caulking position
- v) The caulking cycle is repeated for the other three corners
- w) At the end of the last corner, the electronic system gives consent to return to the start position to the grasping spider
- x) The stopswitch sensors detect the presence in the start position of the grasping spider and give consent to the unloading system to position the
forks - y) Once the forks are positioned under the spider, it releases the frame
- z) The release stopswitch of the
grasping elements 325 give consent to unload the frame by the mobile forks
