Description

The invention relates to a device for the disposal of old glazed windows.

BACKGROUND OF THE INVENTION

Until now, old windows brought from the construction site were thrown into a container and exported to a junkyard or similar place. Since the window frames were stacked in the container undiluted, there were considerable dead spots which required a large capacity of the containers, which made the disposal more expensive.

If the window glass was to be separated from the frame, it had been done by manual labor so far, which in addition increased the cost of disposal.

Swiss Patent No. 400,046 discloses an apparatus for crushing possibly also bulky waste. This device is non-transferable. It comprises one frame with a shear beam as well as a second frame, also provided with a shear beam, which is rotatably attached to its lower edge in the region of the lower end of the rigidly fixed frame on this horizontal axis and rotates continuously by rhythmically. The upper parts of the frames form pressing plates, between which the waste is crushed or broken.

It is an object of the present invention to provide a simplified window disposal device.

SUMMARY OF THE INVENTION

This object is solved by a device according to the invention which separates the old glass from the respective window frame and subsequently breaks up the window frame, the essence of which is

(a) a workbench with a conveyor running along the table on which the window frames are laid flat in succession;

(b) glass drop openings provided with a workbench beneath the conveyor;

(c) a shattering device for shattering old glass, which is on the workbench above the glass-drain openings;

(d) a pedestal which is supported by the ground and supports a workbench and has a container space under the glass-aperture openings;

(e) crushing equipment of glass-free conveyed window frames behind the workbench;

f) under a crushing z-rr and a container for collecting crushed window frames.

Suitably, the conveyor of the workbench has at least two chains endlessly running along the workbench, provided with grippers whose distance is less than the smallest width of the window frames to be disposed of.

In an alternative to this, it is also possible for the conveyor to have a pushing beam along the width of the work table, which is moved along the work table by the drive. In this case, it is suitable that there are retractable or extendable stops (projections) on the window frames to be conveyed at the end of the workbench.

The breakaway device may be a perpendicularly directed impact tool through which the window pane is printed or discharged. There is also the possibility of removing the window frame by passing it through a bending device which bends the frame and thereby destroys its glazing. This can also be done by tearing the window frames in the region of the breaking device to release the glazing. In any case, the loose and shattered old glass falls through the slits for dropping the glass into the lower glass container, while the window-wound, de-glassed, on the workbench continues to transport further up to the shredding device, which may be lever shears, saw and the like . The conveyor flow is controlled by a device which, by means of a mechanical, optical, pneumatic or electrical sensor, detects the exact position of the window frame.

The horses are thrown into the table with a table.

In the work table, the window parts of the second container, which are located under the washing machine, are shattered, so that the old glass is separated from the frame parts. The windows brought from the construction site can be placed on the work table and processed immediately during unloading. This eliminates intermediate storage e. This device, which is the subject of the invention, can also be applied to large construction sites. In this case, it is convenient if the pedestals of the pedestal can be folded to the underside of the workbench when transporting the machine. In this way, the device can be transported in one piece on a truck and can be easily installed on the respective construction site. In order to ensure even filling of the containers, it is advantageous if the pedestal is movable on the ground.

By means of a derived embodiment, the crushing device can be designed as a frame press with the following features:

(a) in the direction of travel of the window frame, the impacting wall;

(b) a draw-in device which transports the window frames against the flange;

(c) a pusher arm at rest outside the direction of displacement of the window frames, which is rotatable from its rest position within the plane of the window frames by its own propulsion relative to the window frame disposed up to an end position approximately parallel to the impact wall;

d) an opening for falling window parts which lies in front of the impact wall and above the second account by a jrier.

With the present invention, the weight of the window sash can be reduced by about 50% by removing the glass. This leads to a reduction in charges for waste exported to landfill. By unfolding the frames, the volume in the container can be reduced by half, so that the removal costs are also considerably reduced. The separated broken glass is transported in a glass container and recovered. which is also financially advantageous.

A device for the disposal of old glazed windows with a part for separating old glass from the respective window frame may contain the following features:

(a) a workbench with a conveyor running along the table on which the window frames are laid flat in a row;

(b) glass drop openings provided with a workbench beneath the conveyor;

(c) a shattering device for shattering old glass which is on a workbench above the glass-drain openings;

(d) under the workbench there is a collecting device for broken old glass which has fallen through the glass-fall openings;

(e) the breaking device is an impact device having rotating impact arms;

t) the impact arms are formed as two-arm levers and are coupled to the driven rotating disk such that the effective impact arm follows the radius of the disk by a certain angle;

g) above the conveyor, there are retainers located between the inlet part in front of the breaking device and the outlet part behind the breaking device.

Such a device can operate independently of whether or not there is a window frame crushing device immediately behind it. It is also independent of the design of the shredder. The collecting device for the broken old glass lying beneath the work table may also be a conveyor, for example. To prevent jamming of the impact arms when striking a hard material, the above mentioned special attachment of the impact arms is used. This effectively prevents the impact arms from being locked by the knuckle effect. In this case, it is advantageous if the impact arms are designed as pairs, the two arms of which independently rotate. If one impact arm hits the window frame, it is ensured that the other impact arm strikes the glass at the edge of the frame.

Preferably, the impact device operates as movable in the direction of travel of the window beams. The impact arms seem to push the glazed window frame in front of them. Particularly in the case of frames with thermal glazing, there is a relatively large overhang of the frame, which creates an impact shadow at the rear frame cross member, viewed in the direction of travel. In order to also remove the edge of the glass, it is advantageous to attach a second, oppositely moving impact device. Both devices can have a common drive.

It is also advantageous to have a glazed slide behind the work table behind the outlet part, free of glazing, through which the frames reach the conveyor, which leads them to the crushing device. This arrangement is advantageous because the bottom device does not depend on the size of the frames.

The crushing device may have a draw-in wedge which takes the window frames and narrows in the direction of their movement and ends with an outlet opening whose height and width correspond to the size of the pressed frame. In this case, it is advantageous if the draw-in wedge is formed on the underside of the conveyor and in the tapered part by a draw-in device.

The pulling device - as well as the conveyor - can be equipped with grippers that circulate more slowly compared to the longitudinal conveyor. In this case, it is advantageous if the drive of the draw-in device is connected to the drive of the longitudinal conveyor by means of a compensating gear. By means of this compensating gear, a chain drive can be mounted on the rocker and can serve, under certain conditions, to adjust the speed.

The whole device, especially the glass breaking device, can be installed in a container that can be moved to any location to reach a mobile device. Special sound-insulated containers may be used, subject to strict noise restrictions in residential areas.

Further features of the invention are the subject of the subclaims and are explained together with further advantages in the following examples.

DETAILED DESCRIPTION OF THE INVENTION

The first exemplary embodiment of the disposal device shown in FIG. 1 consists essentially of a workbench 1 mounted on a pedestal 2, having movable supports 3 on the ground, which are articulated to the workbench 1 and in the shown working position by inserting locking pins or the like The base 2 under the working table 1 forms a collection space for two containers 4,5 standing side by side along the working table 1. FIG. 2 it is evident that the work table 1 together with the base 2 holding it is movable along the containers 4,5.

In FIG. 1, the lower left end of the workbench 1 forms an entry portion 6 for the window frame to be discarded. In the work table 1 there is an integrated conveyor, which in the illustrated embodiment is formed by a plurality of running endless chains 8 equipped with grippers 8 along the work table 1, the mutual distance of which is smaller than the smallest width of the liquidated windows. In this case, the strings 8 can already form 6. The chains 8 can, however, also be mounted in the grooves of the workbench in the entry area 6, with only the grippers 7 projecting above the receiving surface of the receiving table.

The inlet part 6 is connected to the glass-cut notches 9, which are located predominantly in the first half of the work table 1 so that they are located above the container 4, which is to the left in FIG. Above these glazing notches 9 there is shown schematically a breaking device 10 for breaking glass.

At the end of the work table 1 a crushing device 11 for incoming window frames is arranged.

The workbench 1 rises in the upward direction of travel 12 and has an ejection end 13 approximately in the middle of the container 5 shown in FIG. i shown on the right.

The old glazed windows to be disposed are laid one after the other on the lower entrance part 6 of the work table 1, from where they are conveyed by means of a chain conveyor 7,8 in the streams up to the discharge end 13. First, the window frame to be discarded is stopped beneath the breaking device 10 and thus above the slits for the glass overflow 9 above the container. The breaking device 10 may have an impact punch or something similar from above, perpendicular to the frame surface, which forces the window pane down or breaks it from the frame. The cut-offs for the glass 9 may also be formed of a clear width between the chains 8. The broken or extruded glass falls into the container 4, while the glass-free window frame moves further up into the crusher area 11. In this case, for example, in the direction of movement, the forward frame profile can influence the conveyor control by means of mechanical sensors, a photocell and the like. If the crushing device 11 consists of lever shears, the window frame stops when the cross member of the frame is behind the scissors, so that in the first size step the frame of the desired length of the container 5 is cut off at the same time. Accordingly, it progressively advances, mowing until the end cross member falls into 6 lays another frame, so that during the crushing of the window frame the glazing of the next frame is removed.

The crushing device can also be formed by a saw that takes the carriage transverse to the work table L. A solution in the form of a press that is formed by a pusher moving along the work table. This moves to the possible also at the crossbar, catches the frame already in the entrance part 6 and at the end of the work table pushes it to the stop, which is extended or extended. slides into the road. When the stop is extended, the window frame which has been de-glassed in advance is broken.

In a variant solution, the conveyor may be a jaw that engages the window frame, whereby the frame is crushed by tearing the frame so that stoppers are punched into the opening of the frame by which the frame is broken into pieces when the jaw moves.

In order to fill the containers 4,5 evenly with the entire window frame processing device, it moves along them.

Figures 3 to 7 show a second embodiment which differs from the first in that the glass separating device (FIGS. 3 and 4) forms a separate module from the following crushing device, which is shown in FIGS. 5 to 7 in a variant embodiment.

Referring to FIG. 3, the glass separator itself has an upstream input device 14, which may also be designed as an input tray for receiving the window frames 15 to be discarded.

Also on the glass separating device shown in Fig. 3, there is a working table 1 in the direction of displacement 12, along which two mutually spaced chains 8 with grippers 7 pass. The acting forces are discharged by bearings 16 of the gears not shown into frame 17 and supports 3 .

Upon pulling in, the grippers 7 are gripped by a window or a window frame 15 and conveyed via a breaking device 10, which is shown here as an impact device with rotating impact levers 18. The energy of these rotating levers 18 is sufficient to separate the panes from the window. frame and also broke them. The glass fragments fall through the glass drop openings 9 into the container 4 standing under the window.

The removal of the glass-free frames takes place at the ejector end 19. Covers 20, which are located in hazardous locations, ensure operational safety.

The glass removal device of FIGS. 3, 4 may be followed by the breaking device shown in FIG. 5 to 1, which is shown here as a frame press.

The previously de-glassed window frame 15 is drawn into the frame crushing device 11 by means of a draw-in device. This consists of two lamella chains 21 which are spaced apart and move in the direction of displacement 12 and which are connected to one another by plates 22 supported by stationary guide bars 23. The drive of the lamella chains 21 is effected by means of a geared motor 24 and a sprocket 25 .

The rear wall of the crusher 11 in the direction of displacement is formed by an impact wall 26 that extends into the path of the window frames 15 in the direction of travel. In the impact direction the window frame switches off the geared motor 24 and turns on the motor. in the event of a window frame impact, the draw-in device 28, which may also be a gear mechanism for rotating the pusher arm 29. This pusher arm 29 lies in a rest position away from the window frame travel path approximately parallel to direction 12 (see extended position in FIG. 6) and is in the plane of the window frame 15 90 degrees to the final position, which is the impact wall 26, by means of a chain transmission 30, which may be or a worm gearing (see the dashed illustration in FIG. 6). In this illustrated rotation of the push arm 29, the window frame 15 (see the third step in FIG. 7) rotates around a corner which lies at the impact wall 26 of the rhombus and finally breaks into

These pieces fall into the container through the opening 31, which is below the draw-in device and above the aforementioned container.

By squeezing the corners, the window frame is loaded at a more sensitive point, destroying it. This procedure also leading rotated around almost parallel to deform the pieces of the frame and then j ednotli amounting ypadávací find their needs compared to a conventional Schre der ^j ew process only a fraction of energy expenditure and moreover is almost wear-free and very quiet.

The glass and frame parts can then be discharged separately and the volume of the window frames destroyed during disposal.

Figures 8, 9 and 10 show a variant solution of the breaking device 10. An impact device is shown having rotating disks 32 fixedly attached to the shaft! 33 in which the impact levers 18 are in the form of two-arm levers. Each impact arm 18 is attached such that its effective arm 34 is rotated relative to the radius of the disc 32 by an acute alpha angle. This is ensured by the shorter arm 35 of each impact lever 18 leaning against the shaft 33 with its bevel.

Referring to FIG. 10, the impact levers 18 may be designed as a pair of shoulder levers whose impact legs 18a, 18b rotate independently of one another. In this case, the impact levers 18 or 18a, 18b can be inclined by an angle [beta] with respect to the movement of rotation 36 when they strike the glass of the window frame 15, and can engage the shaft 33 in their extreme positions.

In the embodiment of FIG. 8, two impact devices are disposed one after the other, the first working against the direction of movement of the window frames 15 (rotation arrow 37) and the second moving in the direction of movement 12. Further, it is apparent from FIG. The device 10 has an insulating noise cover 38. In addition, the retainers 39 are disposed throughout the region of the smashing device 10, from its inlet to the outlet. The flight holders can be hung on cylindrical sliding mounts to press the window frame 15 under its own weight.

Figures 11 to 14 show a variant solution of the crushing device 11, which can also be applied by itself. Downstream of the workbench 1, behind the exit of the smashing device 10, a chute 40 is provided, through which window frames, free of glazing 15, coming from the smashing device 10,

- preferably a large radius and slightly inclined - onto a conveyor 41 which leads them to a crushing device 11. This device has a tapered pull-in wedge 43 in the direction of movement of the window frames 15, which opens into an outlet opening 44 with a height and width equal to frame. This draw-in wedge 43 is formed from the underside by a conveyor 41 and from the side by a draw-in device 45. In this draw-in device 45 the chain 47 is provided with grippers 46 that move more slowly than the conveyor 41.

The conveyor 41 has - like the pull-in device 45

- two parallel side-by-side infinite and lateral out of e 48, which are interconnected by angles 49. These, with their projecting flanges 50, form a grid for laying the window frames 15 and adjacent ones. a transport platform enclosed by flanges 51. For the chains 47 and the pulling device 45, this solution is shown in Fig. 14.

In FIG. 12, the arrow 52 shows the direction of access of the window frames 15 from the smashing device 10. The arrow 53 shown at right angle indicates that the window frames 15 can also be fed into the crushing device 11 in the conveyor direction 42.

The drive of the draw-in device 45 is effected by the drive 54 of the conveyor 41 via an intermediate differential 55, which, according to FIG.

It can be seen from FIG. 11 that the window frames 15 standing on the conveyor 41 are guided between the two side walls 57.
