GLASS BEVELING MACHINE

Description

Technical Field

[0001] This invention relates to a machine as per the preamble of claim 1. An example of such a machine is disclosed by US 2 551 332 A.

Background Art and disclosure of invention

[0002] Bevelling machines for the glass sheets use containers with big rubber bellow bonnets to work in the different angles and in the same time to cool the wheels without that the cooling fluid goes out. The bellow conformation and the rubber elasticity allow the traverse of the swinging wheels console. Whatever is the bellow conformation, these bonnets always limit within a determinate angle, the wheels traverse and cause big problems because of the accumulation of grinding wheels residual that putting down the bellow cause considerable damages at the bonnets. A bevelling machine with a swinging unit is described in US 2 551 332 A.

[0003] The current invention, has resolved this big problem eliminating the use of the bonnets and using a new type of container. It is fixed on the swinging console of the machine and it makes possible either the containing of the wheels without any loss of fluid or the free traverse of the swinging console from zero to ninety degree.

[0004] The object of this invention is acheived by the machine of claim 1.

[0005] Figure 1 shows a frontal straight machine to work mitre bevel, bevel in its different gradation and flat edge with arris on the glass sheets.

[0006] In the figure we can noticed the swinging console (1) and the fixed motors-spindles X and Y to grind and to polish the arris on the flat edge working. The view B, figure 2, shows the swinging console (1) which carry the different groups motor-spindles wheel, that driven by a reducer, screw and scroll (2), does a rotation from zero to ninety degrees around the empty centre (4), doing as fulcrum point on a circular support (3). The numbers (5-6) represents schematically the front and back track that have the function of advancement and keeping of the glass sheets.

[0007] In the figure 3 view C is represented in section the swinging console (1), with the motor-spindle-wheel group (7) in the position of ninety degrees measured among the inside face of the two tracks (5-6) and the higher face of the wheels. The new system of container of the wheels (8) is showed in this drawing too. This container fixed on the swinging console (1), for its conformation, makes possible the spraying on the wheels (24) at any angle without loss of fluid or sprinkling but from the special draim (23) where also the working residual are send out.

[0008] In this container, the open higher part is closed for all its length by two thin plates like rubber (9-10). They make possible the rotation of all the swinging group at any angle, as exemplify showed also in the C view in the figure 4, angle 45 degree and in the figure 5 angle 32 degree, keeping close the container without any loss of cooling fluid. In the figure (3-4-5) of the C view are represented the Cerium Oxide mixture jets (11) that continually flows on the bottom of the container by a closed circuit system and the compressed air jets (12) that intervening only when the glass sheets pass on the wheels. The air compressed jets change the direction of the fluid of the Cerium Oxide mixture pulverizing it on the wheels.

[0009] In the figure 6 view A, a realization of an automatic synchronized in vertical movement of the front track (5) is represented. It is driven by a sector gear (13) fixed on the swinging console (1) and it causes the rotation of a double gear (14), also it connected with pinion and chain (15), causes the rotation of a cam (16) assembled on a tie-rod (22), which connects the opposite cam and by its rotation caused the go up and go down of the sliding support (17) solid with the front track (5), always in the same determinate height with relation to the gradation in which is the swinging group.

[0010] A safety system set combined to the sliding support (17) where a lever mechanism (18) is pivoted on the chassis of the machine on the point (19) and have a supporting bearing (21) for the sliding support (17). It is kept in the vertical normal position by a ratchet with a round tip (20) which have a set spring that keeps it pressed and hammered into an adequate slot on the chassis of the machine. If happen excessive pressure on the supporting bearing (21) because of the introduction of a glass sheet with a more thickness than that the machine as been arranged it releases the ratchet (20) and mechanism (18) rotates outward causing the immediately widening of the spar (5), stopping the advancement by a micro switch and avoiding very serious damages to the member which keeps and moves the glass sheets.

Claims

1. Machine for producing mitre bevels of different gradation or flat edges on glass sheets or other hard materials with parallel faces, wherein a container (8) of adequate shape is used to contain the operating wheels (24) and their cooling system in order to avoid the loss of cooling fluid or their sprays, said container is (8) anchored in the same console where the operating wheels (24) are located and performs together with the wheels, a rotating movement from zero to ninety degrees, characterised in that in order to avoid loss of cooling fluid, the front closing of the wheels container (8) is realised by the longitudinal bulkheads (9,10)that are located both in the front part and in the back part of the container (8), and are made of flexible material, for example rubber, or are realised by means of telescopic bulkheads, and are working in an opposite system, i.e. when the wheels' inclination goes from zero to ninety degrees the front bulkhead (9) uncovers itself, thereby widening its visible area and in the same time the back bulkhead (10) comes inside the container (8), thereby disappearing from view.

2. Machine for producing mitre bevels of different gradation or flat edges on glass sheets or other hard materials with parallel faces as in claim 1, characterised in that said longitudinal bulkheads (9,10), in order to close the container, are fixed either in the upper spar or in the same swinging container.

3. Machine for producing mitre bevels of different gradations or flat edges on glass sheets or other hard material with parallel faces as in claims 1, characterised in that a front track, which holds and advances the glass sheets together with a back track, is vertically movable to work bevel.
