DE3008760C2 - Device for forming groups of spaced briquettes - Google Patents

Description

The invention relates to an apparatus for forming groups of spaced briquettes of the type listed in the preamble of claim 1.

Such grouping devices are required, e.g. B. for transferring bricks to bricks after the cutter. For the production of e.g. B. from Large blocks with low strength when wet also need to be grouped fully support in order to prevent sinking into the transport device.

From DE-AS 16 84 038 and DE-AS 22 04 739 and from DE-OS 27 13 895 grouping devices are known. These devices always intervene Transport means into another one that the briquettes are only partially supported during the transport process are. These devices are not suitable for grouping low strength shapes.

The invention is based on the object of creating a grouping device with which brick bricks fully supported by low intrinsic rigidity when wet, while at the same time an already warped group of moldings

has reached the tap position.

This object is achieved according to the invention with the embodiment characterized in claim 1

The basic idea of using two conveyors, one of which picks up moldings while at the same time which gives off other briquettes is also included in DE-AS 24 5 * 703. But this affects one completely different device, namely an elevator for

ίο Picking up and setting down bricks that are brought in, Roof tiles or concrete blocks. The elevator has two independently drivable Chain conveyor on, each with the briquettes underg Angular supports are provided.

With the well-known elevator there is neither warping from formations at a mutual distance still the full support of the briquettes during the warping accessible.

The advantages achievable with the invention are that the briquettes during the group formation tmd of the transport in Afagafaepositiön always fully supported remain and that with the warping of the moldings during the dispensing of moldings that are already warped an extremely powerful device is created with little structural effort.

Further developments of the invention are in the subclaims marked

An embodiment of the invention is shown in the drawing and is explained in more detail below It shows

F i g. 1 schematically shows a side view of the device when transferring the moldings;

F i g. 2 schematically shows a side view with the group of moldings in the transfer position;

F i g. 3 shows a plan view with the group of moldings in the transfer position; and

F i g. 4 shows a section through the grouping device along the line IV-IV in FIG. 3.
On a conveyor belt 1 enkonK: i "mold pieces 2 are / b taken and from a tape segment 3a while warped in a known manner at a distance from the length of the band segments 3a / b in the conveying direction of the length corresponds to at least about a warped molding Group 4 after. Completion with the belt segment 3a / b in the transfer position 5 is conveyed and stopped, while at the same time a new belt segment 3b / a appears at the transfer point following the conveyor belt 1 to form the following group of moldings 4.

After moving the Formlinpsgruppe 4 from the band segment 3a / b z. B. by means of a gripper 6, the released band segment 3a / b is set in motion again and brought to the rear end at a higher speed than the warping speed and in connection with the band segment 3b / a engaged for warping. The band segments 3a and 3b each have its own drive motor 7a / b.

The belt segments 3a / b are attached to one another on chain conveyors 8a / b with coaxially arranged chain wheels of the same circumference in such a way that they can be moved at different speeds, driven independently of one another. For this purpose, the belt segments are set in motion again from the tapping position at such a higher speed than the drawing speed that the belt segment returning from the tapping position is connected to the rear end of the belt that is currently drawing a row of molded products.

element is brought. The deflecting chain wheels 9a / b of each belt segment 3a or 3b are rotatably arranged on the drive shaft Mb / a of the other chain conveyor 86, 8a, which supports the drive chain wheels iOb / a in a rotationally fixed manner. '

Claims (4)

Patent claims: 1. Device for forming groups of spaced briquettes with a closed briquette rows feeding conveyor, as well as with one of this taking over, rotating at a higher speed conveyor, which brings the series of moldings at a distance from each other and promotes in a tapping position, characterized in that the faster The circulating conveyor consists of two belt segments (3a or 3b) that rotate in the same path and can be driven independently of one another, the width of which corresponds to the width of the moldings and the length of which in the conveying direction corresponds to at least the length of a group of moldings spaced apart, so that the belt segments on two chain conveyors lying one inside the other ( Sa, Sb) are arranged with coaxial chain wheels (9a, 9b or 10a, 10b) of the same circumference and can be reversed to different rotational speeds. 2. Apparatus according to claim 1, characterized in that each chain conveyor (8a, Sb) has its own reversible drive motor (7a, Tb) 3. Device according to one of claims 1 and 2, characterized in that the deflection chain wheels (9a, 9b) of each chain conveyor (8a, 8b) rotatably on the anti-rotation shaft (l Ii, 1 \ a) of the other chain conveyor are arranged. 4. Apparatus according to claim 1, characterized in that that the band segment a> * s of the tapping position set in motion again at such a higher speed than the grouping speed are driven that the returning from the tapping belt segment to Brought connection to the rear end of the straight rows of moldings receiving tape segment will.
