Abstract

An apparatus for manufacturing green bricks from clay for the production of bricks contains means (10) for arranging cylindrical openings in the bricks. Such bricks can be mutually coupled by means of rods, while the drying time of the green bricks is moreover shortened. The apparatus comprises a frame (1) for supporting an endless chain conveyor (2), moving in the direction of the arrow P1, on which are placed rows of mould containers (3). After feeding, the mould containers are carried beneath the device (10) for making openings in the green bricks in the mould containers. The device (10) comprises a frame (20) and a frame (23) vertically movable. The frame (23) carries a plurality of cutting cylinders (27) and ejectors (28). During operation, the frame (23) moves downwards and the cylinders (27) penetrate into the green bricks. During the following move upwards of the frame (23), the cylinders (27) carry the cut-out of the green bricks, so that cylindrical openings are created in the green bricks.

Description

APPARATUS FOR MANUFACTURING GREEN BRICKS FROM CLAY FOR THE PRODUCTION OF BRICKS
The invention relates to an apparatus for manufacturing green bricks from clay for the production of bricks, in particular bricks whereof the main surfaces have continuous openings, comprising a circulating conveyor for carrying mould containers, means placed above the conveyor for forming and carrying balls of clay into the mould containers, placing means for placing carrying plates on the mould containers and means for turning over and emptying the mould containers. Such an apparatus is shown inter alia in "Handbuch fur die Ziegelindustrie", Willi Bender et al., 1982, Bauverlag GmbH, Wiesbaden and Berlin, ISBN 3-7625-1485-2, p. 213.
The arrangement of for instance cylindrical continuous openings in bricks can have different purposes. It is known to mutually couple bricks with openings using reinforcing rods which are placed through the openings placed in line, in order to strengthen the mutual bond of the bricks. Such constructions are for instance used at those locations where the danger of earthquakes is a factor which must be taken into consideration in the building industry. It is also possible to apply such constructions to manufacture panels of bricks. It has also recently been established that in the production of such bricks an energy-saving can be achieved compared to the production of classic closed bricks. This is because of the fact that due to the openings the surface exposed to the air is considerably enlarged so that a shorter drying time will suffice, optionally at lower temperature.
It is the object of the invention to provide the known apparatus with means such that such bricks with continuous openings can be manufactured in commercial manner.
For this purpose the known apparatus is characterized by means placed in front of the placing means as seen in the transporting direction for cutting out of the green brick and removing from the green brick a part of the green brick extending along the height of the green brick.
Using the said means a part is cut out of the plastic green brick, the cut-out part is removed from the green brick and is discharged.
The means can consist of a cylindrical cutting member and an ejector pin arranged slidably therein. During operation the ejector pin is displaced along a part of the length to a point inside the cylindrical cutting member, whereafter the cutting member is pressed into the green brick, the cut-out part is taken upward along with the cylinder and the cut-out part is subsequently ejected by sliding the ejector pin outward. The apparatus is preferably characterized by a drive mechanism for displacing a cylindrical cutting member in the direction of a mould container and displacing the ejector pin in the cutting member, in order to enable the above described movement to be carried out. The invention will be further described in accordance with an embodiment with reference to the drawings.
In the drawings:
Fig. 1 shows a perspective view of an apparatus according to the invention,
Fig. 2 shows a perspective view of a part of the apparatus as designated with an arrow II in fig. 1, and
Fig. 3 shows a detail of fig. 2 in the successively occupied operating positions. The apparatus according to fig. 1 comprises a frame 1 for supporting an endless chain conveyor 2 on which are placed rows of mould containers 3. The endless conveyor 2 moves intermittently in the direction of the arrow PI. During the movement the mould containers are carried beneath a clay filling device 4. Arranged in this clay filling device 4 is a stirring member 5 which is rotated using the drive motor 6. Clay is supplied to the device 4 at the top of the device using a conveyor belt 7.
Arranged behind the clay feeding device 4 as seen in the transporting direction is a pressing device 8 which carries clay fed from device 4 into the mould containers 3. The pressing mechanism 8 is pivotable round a horizontally arranged shaft 9. After trimming, the mould containers are carried beneath the device 10 for making openings in the green bricks in the mould containers. This device 10 according to the invention will be described further. The mould containers then move under a plate supply device 11. The supply device 11 carries plates 12 unto the row of mould containers 3. Situated at the turning point 13 of the chain conveyor is a turning device 14 which turns over and carries onto a conveyor 15 the plates which have lying thereon the green bricks released from the mould containers. The conveyor 15 moves in the direction of the arrow P2 and carries the plates with the green bricks lying thereon to a drying device. In a lower part of the conveyor 2 the empty mould containers move successively past a washing device 16 and a sand-covering device 17 before the next operational cycle begins after the turning point 18.
The device 10 (fig. 2) comprises a frame 20 and a frame 23 vertically movable therein along guides 21, 22. The frame 23 is driven vertically by hydraulic or pneumatic cylinder-piston combinations 25, 26. The frame 23 carries a plurality of cylinders, for instance 27. An ejector 28 (fig. 3) is movable in each cylinder. The ejector 28 is supported by a plate-like member 30, while cylinder 27 is supported by a plate 29 arranged parallel to plate 30. The plates 29 and 30 and therefore cylinder 27 and ejector 28 are displaceable relative to each other by means of the hydraulic or pneumatic cylinder-piston combination 31. During operation the frame 23 moves in downward direction until cylinder 27 penetrates into the green brick in the mould container. Due to the adhesive power of the clay the cylinder carries a cut-out part of the green brick along in upward direction during the return movement, so that a cylindrical opening is created in the green brick.
A frame 33 movable on guides 32 and carrying an endless conveyor belt 34 is subsequently moved in a direction opposed to the direction of movement (P3) of the chain conveyor 2 until a position under frame 23 is reached. The plate 30 is then moved in downward direction by driving the plunger 31 whereby the ejector 28 ejects the clay from the cylinder. The ejected cylindrical portion comes to lie on the endless conveyor belt 34 and is carried away in the direction of arrow P4. The operating cycle is hereby completed.
It is noted that the removal of a cylindrical portion from the green brick according to the invention takes place during standstill of the chain conveyor which is moved intermittently.
