To fulfill this the food and the joints the purpose, different dimensions and shape of the components, so that despite dimensional and shape differences set the components in straight layers or can be walled.

At the Building construction it is known inter alia, juxtaposed or bricked components to stick together, with thin Joints are sought to save glue.

It But also for a conventional construction thin joints sought to grout material or food too save up.

With However, thin joints can only be worked out if the components with respect to each other and also side by side lying surfaces and associated altitude and horizontal dimensions are the same.

To plan each other or adjacent surfaces of the components, it is from the document DE 10 2005 043 548 A1 known to plan a side surface of horizontally and successively conveyed on a conveyor brick bricks to grind. If the components or bricks are to be ground flat on both sides, it is from the DE 10051253 A1 It is known to transport the series of components between two grinding wheels, whereby they are simultaneously ground on both sides. In this known grinding machine, two grinding devices are arranged one behind the other lying on both sides in the direction of passage of the grinding machine, wherein the last grinding device in the passage direction abrades a second layer, for. B. a fine layer.

Of the Invention is based on the object in a present grinding machine to simplify the construction and preferably to design it that they consist of several, z. B. at least partially prefabricated, Assemblies can be assembled. It is also aimed at a construction to find, which allows the grinder either with one or more grinding devices form and thereby a simple and inexpensive to produce and in particular also easy to install or dismantle design to find.

These The object is solved by the features of claim 1. Advantageous developments of the invention are in subclaims described.

at The grinding machine according to claim 1, its frame has a rear and a front end portion passing through one or more, in between extending longitudinal parts are interconnected. The The grinding machine according to the invention thus exists from at least three modules, namely two end parts and one or more longitudinal parts extending therebetween, the aneinanderetzbar in both end of the grinding machine and can be mounted or dismounted. The end parts and the longitudinal part or the longitudinal parts can thereby at least partially premounted or prefabricated with associated attachments become. It is preferably provided that the respectively associated Attachments are stored only at the associated end or long part, so that a storage of the attachments on the associated end part and at the same time also on the adjacent long part or vice versa deleted. As a result, the construction, manufacturing and assembly or Dismantling much easier.

One Another advantage of the embodiment of the invention is that with respect to the or the long parts in each case several longitudinal parts are available, which differs in the number of existing grinding devices and distinguish a resulting different length and optionally mountable as required by the number of grinding devices are. In this case, a bearing at least one grinding device Cross slide with the grinding device and / or other attachments be pre-assembled or not. This makes it possible Grinding machines with one or more grinding devices to assemble, for. With one, with two or three sanders, and doing the or their respective longitudinal parts and cross slide to use, with the same end parts available are, which optionally with the associated longitudinal parts and transverse slides are mountable. The for storage of the cross slide required bearing and guide elements are on the End parts arranged and prefabricated.

Also in the grinding machine according to the invention can one or more grinding devices on one or both Be arranged sides of the passage.

To a grinding machine of the present type also special requirements are made in terms of their adaptability to the width or to different widths of the components in order to differentiate the distance to the components or to be able to set very wide components. It is desirable to be able to adjust the grinding housing and the grinding wheel of the grinding device independently of each other to certain or different transverse dimensions of the moldings. It should be possible to adjust the sliding housing, taking into account a safety distance from the components as close as possible to the components in order to ensure the effectiveness of an integrated into the sliding dust extraction device. But it should also be adjustable independently of the grinding wheel, the grinding wheel to z. B. to be able to set a cutting depth in plan grinding.

Of the The invention is therefore based on the further object in a Grinding machine of the present type, the adjustability of the grinding device to improve. In addition, the aim is a construction to find a targeted and easy setting of both the Abrasive housing and the grinding wheel of the grinding device allows. In addition, the assembly should also or disassembly of the grinding device to be improved. Furthermore is sought to find a construction in which the adjustment for the sliding housing and the adjusting device independent of each other for the grinding wheel are and thus optionally one of these adjusting devices are operated can, without the other adjustment is adjusted with.

These The object is achieved by the features of the independent claim 3 solved. Advantageous developments of the invention are described in the accompanying subclaims.

at the grinding machine according to the invention according to claim 3, the grinding device has a sliding housing and a rotatably mounted therein grinding wheel, wherein the sliding housing and the grinding wheel are each mounted on a cross slide, by a drive in a respective associated transverse guide is slidably mounted back and forth, and wherein the sliding housing carrying cross slide and the grinding wheel bearing cross slide are mounted independently displaceable. at Such an embodiment, the sliding housing and the grinding wheel adjustable by selective back and / or pushing, this can be done independently of each other, so that an optional adjustment can be made and at an optional Setting the setting of the other setting is not adjusted. This is a simple handling-friendly and targeted and independent adjustment of the grinding housing and / or the grinding wheel with respect to the passage or the ensured therein component.

It is also advantageous, the transverse guide for the slider carrying the cross slide by a rear and a front transverse guide to form, the rear transverse guide part at the rear end part and the front one Transverse guide part is arranged at the front end part. These Design allows a similar embodiment of End parts even if the slider bearing the transverse slide and the remaining longitudinal parts for an optional Number of grinding devices of different lengths are. Consequently, this embodiment also contributes to for a grinding machine of an optional number of grinding devices End parts and longitudinal parts of an optionally determined number Grinders and the associated length to use.

at a grinder designed for different widths adjustable to be ground components, it is advantageous in particular the lower conveyor or the upper conveyor with respect to their width so adjustable designed that they are adequate to the width the components is or are adjustable and thus in the outdoor areas the components can interact with these, increasing stability the mounting of the components is improved in the promotion.

alternative it is advantageous instead of one with respect to their width adjustable lower or upper conveyor to arrange each two lower and upper conveyors, their distance from each other adequate to the existing width the components is adjustable. Also by this can the left and right conveyors on each Such a width can be adjusted that they are compatible with the components interact in their outdoor areas.

there It is particularly advantageous that on the respective page associated lower or upper conveyor with the associated Sliding housing and / or the cross slide carrying it so connect so that it forms a unit of motion and therefore a special transverse drive for the or the conveyors can be omitted.

As already mentioned, is in such a grinding machine, which is suitable, the components at two opposite Grind pages at the same time, the opposite Machine side with regard to the grinding device (s), of this carrying cross slide and the respective grinding wheels As well as their drives arranged in mirror image, with a mirror image function takes place.

For a cross slide, the respective transverse guide is problematic, because it is in the cross slide, especially if thereon several grinding devices are arranged one behind the other, is a relatively long and narrow component. It is therefore advantageous to combine the cross slide drive with a synchronizing device, which ensures uniform movements of the rear and the front end portion of the cross slide. This makes it possible to arrange the cross slide drive either at one of the two end regions of the grinding machine, preferably at the front or at the rear end part. The synchronization device can, for. B. have a longitudinally extending synchronizing shaft, which is connected in both end regions each with a crank mechanism for moving the ends of the cross slide.

in the However, within the scope of the invention, the synchronization device can also be two Have transverse drives for the cross slide, in the End regions of the grinding machine are arranged, preferably at the end parts, and the ends of the cross slide across either and can move evenly.

For two opposite each other and that at least a corresponding sliding housing bearing cross slide it is advantageous to use a transversely extending motion reversal device connect with each other so that only one drive motor is sufficient to move both cross slides towards or away from each other. In this case, it is advantageous in the presence of two two transverse slides arranged opposite each other Motion reversers in the end regions of the cross slides, preferably at the end parts, store, resulting in a simple Construction and safe function when moving the cross slide results.

In further subclaims contain features that are simple and favorable in terms of integration and connection Ensuring constructions under function and also to lead small constructions, the sufficient space between the components and thus a favorable accessibility allow for production or adjustment.

following the invention is based on advantageous embodiments and design details and related drawings closer explained. It shows

2 the grinding machine in the side view;

3 the grinder in front view;

4 the grinding machine according to 1 in a so-called exploded view;

5 a grinding machine according to the invention in a perspective view from the front and from above in a modified embodiment.

The in their entirety with 1 designated grinding machine serves to the components 3 to grind flat on two opposite sides, preferably on the horizontally opposite sides. This is done in a longitudinally through the machine 1 extending passage 4 through which the components 3 with the help of a conveyor 2 lying one behind the other and continuously from the rear end to the front end of the grinder 1 be encouraged.

The feeding of the components 3 to the input end and the further promotion of the components 3 from the exit end of the grinding machine 1 takes place in each case by suitable supply and continuation conveyors, which for reasons of simplicity as arrows 2d . 2e are shown.

In the embodiments of the grinding machine to be described later 1 are the same or comparable parts designated by the same reference numerals.

The grinding machine 1 has a supporting body in the form of a frame 6 on, which consists of three main groups, namely a rear end portion 6a , a front end part 6b and a middle part 6c consists, which is formed in the present embodiment by a plurality of juxtaposed and superimposed longitudinal parts, with the end parts 6a . 6b are connected, z. B. by screw.

Furthermore, the grinding machine 1 several functional groups, namely the conveyor 2 and one or more, in terms of passage 4 preferably arranged opposite one another grinding devices 7 , each a sliding housing 8th and a rotatably mounted therein grinding wheel 9 each having an adjusting device 11 respectively. 15 with a transverse guide 12 respectively. 16 , a cross slide 13 respectively. 17 and a drive motor 14 respectively. 18 transversely adjustable and adjustable. Besides, the grinding wheel is 9 on the corresponding cross slide 17 rotatably mounted and by a drive motor 19 rotatable for grinding operation.

It is the purpose of the sliding housing 8th the, in particular, identically formed, grinders 7 to pick up and remove the grinding dust that accumulates during functional operation. These are the sliding housings 8th , z. B. underside, each a suction or a suction 21 ( 4 ), which are connectable to a suction for sucking and continuing the suction dust.

Due to the transversely directed adjustability of the sliding housing 8th it is possible, with invariable widths b of the components 3 the transverse distance between the components 3 and the sliding housings 8th to vary and adjust, and thus to improve the effectiveness of the grinding dust extraction. In this case, with respect to the passage direction 4a different sized transverse distances between the components 3 and the sliding housings 8th be set.

By contrast, the transversely directed adjustability of the grinding wheels serves 9 in addition, the grinding depth or cutting depth for the associated grinding wheel 9 adjust.

Both adjusting devices 11 . 15 However, they are also suitable positions of the sliding housing 8th or grinding wheels 9 each to different widths b of the components 3 adapt.

The preferably oppositely arranged grinding devices 7 are with respect to the vertical longitudinal center plane E1 of the grinding machine 1 or the passage 4 arranged mirror-symmetrically, resulting in a mirror image adjustment and adjustment of the opposite grinding devices 7 result, which is understandable without further description of the adjustability and adjustability. This also applies to the mechanisms of the grinding devices described below 7 and also for the still to be described adjusting or adjusting devices.

The grinding devices 7 are on the middle part 6c stored, which is formed in the present embodiment of a plurality of spaced apart with a transverse distance long parts, which is best 2 and 4 is recognizable. Accordingly, the middle part 6c an upper and outer side member 22a on, in an inward distance z. B. same upper side member 22b is adjacent. In a downward distance from inner side members 22b is a lower side member 22c arranged, of which one or more distributed over its length arranged support columns 22d up to the upper side member 22b extend and support this. The side members 22a . 22b . 22c are with forehead parts 23 the end parts 6a . 6b connected, in particular screwed. The forehead parts 23 can be formed by plates with recesses 23a are formed T-shaped in each outer and lower corner region.

The end parts 6a . 6b or the forehead parts 23 have in their lower outer two two sides arranged feet 6d on, which are the deepest parts of the frame 6 form, so that it has a distance from the ground in the other lower areas.

On the upper side rails 22a . 22b can be at a longitudinal distance from each other elevated supports 24 be arranged, on which the grinding wheels 9 and their adjustment 15 carrying support plates 25 rest and are attached. On the support plates 25 is the respective cross slide 17 arranged and in the, z. B. by on the support plate 25 fixed crossbars 16a formed, transverse guide 16 slidably mounted back and forth. The associated adjusting device 15 can by a spindle drive 26 be formed, the spindle by the drive motor 18 and an associated reduction gear is rotatable. The transverse stroke of the adjustment 15 or the grinding wheel 9 can z. B. to be many times greater than it for setting depths or the adaptation of different widths components 3 is required. Due to this relatively large transverse stroke leaves the grinding wheel 9 by a correspondingly large trained mounting hole 27 in the outer wall of the grinding housing 8th Adjust to the outside so that they are outside of the sliding housing for repair or maintenance 8th is easily accessible.

Every grinding device 7 or grinding wheel 9 or each cross slide 17 is an associated support plate 25 assigned. The cross slide 13 is below the support plate 25 arranged and independent of the cross slide 17 stored and adjustable. In this case, the cross slide 13 with regard to the associated cross slide 17 inside or to the passage 4 be offset.

The support plates 25 each form with the associated and arranged on it cross slide 17 , Rotary drive motor 18 and the grinding wheel 9 a prefabricated unit 28 , which can be optionally mounted on one of the three existing grinding sites.

In contrast, the transverse guides 12 and the cross slide 13 for all existing sliding housings 8th , here on each side three pieces, formed together, with the cross slide 13 is designed to be long enough to the sliding housing 8th to wear.

In the present embodiment is the cross slide 13 also a side member 31 that extends to the end parts 6a . 6b extends, wherein the rear and front so as each in guiding contact with each other standing pairs of guide surfaces 12a . 12b the transverse guide 12 are arranged at such a longitudinal distance from each other that the cross slide 13 leading guide surfaces 12a at the respective end part 6a . 6b are arranged.

In the present embodiments, the cross slide 13 of such a length that it divides the dividing T between the end parts 6a . 6b and the middle part 6c surmounted so that both pairs of guide surfaces 12a . 12b at the respective end part 6a . 6b are arranged. How to look best 4 reveals, one dominates the cross slide 13 forming and the sliding housing 8th supporting side member 31 the forehead parts 23 in a recess 23b whose along the direction of movement of the cross slide 13 , here horizontally, directed dimension c is so much larger than the corresponding transverse dimension of the cross slide 13 in that this is its transverse movement in order to adapt to different widths b of the components 3 can perform.

How best 1 it can be seen, are the guide surfaces 12a at the rear of the rear end part 23 and at the front of the front end part 23 arranged. At the guide surface 12a is in each case a transverse to the passage direction 4a extending and upright arranged guide plate 12c with a rear or front guide surface 12b slidably mounted. The or the cross slide 13 each extend to the associated guide plate 12c and are attached to this. To ensure the desired transverse direction can be between the guide surfaces 12a . 12b at least one guide bar 12d on the one guide surface, z. B. 12a , be formed in a guide groove 12e in the other guide surface, z. B. 12b , led.

It is to simplify the drive on both sides of the passage 4 arranged cross slide 13 advantageous between the mutually transversely opposed adjusting devices 11 a motion reverser 32 to arrange the transverse movement of a cross slide 13 in the opposite transverse movement of the opposite cross slide 13 transforms. They are preferably two reversers 32 present, each in the end regions of the cross slide 13 arranged and effective. The reversers 32 are preferably at the end parts 6a . 6b arranged and stored, in particular on the back of the rear end part 23 and at the front of the front end part 23 ,

Out 1 and 3 let the configuration and arrangement of the front reversing device 32 of the present embodiment. It has two pendulum rods arranged in a pendulum manner in a vertical plane 32a on, in their pendulum center position approximately along the transverse direction of movement of the cross slide 13 , here horizontally, extend and with their opposite ends by a joint 33 vertically pivotable directly or indirectly with the associated guide plate 12c are connected. At their ends facing each other are the connecting rods 32a through a joint 34 vertically swiveling with a swiveling part 35 connected to the joints 34 opposite each other in parallel to the passage direction 4a extending pivot axis 36a may be formed by a swash plate or a pivot lever. The swivel part 35 can z. B. between the transversely opposed guide plates 16c on the front part 23 or end part 6a . 6b through a swivel joint 36c be mounted pivotally. The swivel part 35 and a connecting rod 32a each form a crank gear or two counter-rotating crank gear.

Because of the relatively large length of the cross slide 13 in comparison with its width is its transverse direction 12 or his transverse drive problematic. Around the two ends of the cross slide 13 To move evenly and to ensure a small and simple design, it is advantageous with the adjustment 11 a synchronization device 36 To combine, the even transverse movement of the ends of the cross slide 13 guaranteed. As it turns out in particular 1 . 3 and 4 is the synchronization device 36 z. B. by a longitudinally extending synchronizing shaft 36b formed, extending from the rear end part 6a to the front end part 6b extends and in their end regions in each case by a transmission with the end regions of the cross slide or 13 or with attachments of the same, see guide parts 16c , connected is. Such a transmission is in the embodiment in each case by the pivoting part 35 and the associated connecting rod 32a educated.

For a grinding machine 1 that only have a cross slide on one side 13 for at least one grinding device 7 has, it requires the back and front only a simple transmission or crank mechanism for moving the cross slide 13 , In the presence of two arranged on both sides cross slides 13 are the ends of the synchronizing shaft 36b each with two counteracting gears, here two counteracting crank gears, drivingly connected.

In the context of the invention, the same running device 36 alternatively be formed by a rear and a front drive motor 14a are arranged, which are the rear and the front end of the cross slide 13 or attachments thereof (guide plates 12c ) alternately back and forth move evenly, with the synchronizing shaft 36b can be omitted. If on both sides two cross slides 13 with grinding devices 7 are arranged, the above-described alternative embodiment with respect to the vertical longitudinal plane E1 may be formed in mirror image, so that inversely effective Verstellvorrichtungsteile 11a . 11b available.

When the synchronizing shaft 36d is present, it is in the swivel joints 36c stored, with the pivoting parts 35 or pivot lever are mounted in their end regions.

In the 1 invisible rear reversing device 32 and synchronization device 36 are regarding an in 2 shown vertical transverse center plane E2 arranged and formed mirror-symmetrically. The synchronization device 36 and / or the rear and front reversing devices 32 ensure a non-glitching and clamping-free transverse movement of the cross slide or 13 in the transverse guides 12 on one or both sides of the passage 4 ,

It is the purpose of the conveyor 2 , the construction elements 3 longitudinally through the passage 4 to promote and in each case hold so strong that the grinding devices 7 the surfaces of the components facing them 3 can grind. To a corresponding temporary mounting of the components 3 To ensure it is beneficial to the components 3 each clamp between two mutually transversely opposed clamping elements, with the speed of movement of the conveyor 2 through the passage 4 are movable and are arranged one above the other in the present embodiment. The clamping elements are preferably by circulating conveyor belts 37a . 38a formed, which are supported against a thrust sliding against a support surface, so that they with clamping pressure against the components 3 can be effective.

In the embodiment, the lower and upper clamping elements are thus each by a longitudinal direction of passage 4a revolving belt conveyor 37 . 38 formed, whose endless conveyor belts 37a . 38a revolve around end pulleys, the components 3 between the upper tower of the lower conveyor belt 37 and the sub-tower of the upper conveyor belt 38 be promoted and held. As 3 clearly indicates, has the conveyor 2 two lower and in a transverse distance juxtaposed belt conveyor 37 and an upper center belt conveyor 38 on, reducing the stability of the mounting of the components 3 is enlarged when conveying. But it can also above two transversely spaced from each other belt conveyor 37 be provided.

To the holder of the components 3 When conveying to further improve, it is advantageous, the lower conveyor 2a , here are the lower belt conveyors 37 to arrange transversely adjustable in an adjustment to them to components 3 to adapt to different width b and to allow the lower conveyor 2a the components 3 supported at a small distance from their lower lateral edges, eliminating the mounting of the components 3 is stabilized further.

A particularly advantageous embodiment is the lower conveyor devices 6a at the respective cross slide 13 or on the respective associated sliding housing 8th to attach so that the lower conveyors 2a a rigid movement unit with the associated cross slide 13 and / or the associated sliding housing 8th form. In this embodiment, the adjustment and adjustment of the lower conveyor devices takes place 2a or lower belt conveyor 37 inevitably when adjusting and adjusting the associated cross slide 13 or grinding housing 8th so that a special holder, guide and adjustment device for the lower conveyors 2a or belt conveyor 37 eliminated.

The transverse guide 41a . 41b is in an upright guide frame 43a . 43b , z. B. to one side of the grinding machine 1 offset, arranged. The cross slide 42a . 42b can each be transversely adjustable by a spindle drive whose drive spindle 44a . 44b from the cross slide 42a . 42b extends upward, an upper guide frame portion 43c passes through and is rotatably mounted thereon. Two more lateral guide frame sections 43d extend from the associated front part 23 up to the upper guide frame section 43c ,

It is preferably a common drive motor 45 for both height adjustment devices 39a . 39b provided with the height adjustment devices 39a . 39b is in drive connection, for. B. by a the rear and the front drive spindle 44a . 44b each by a suitable gear, z. B. a bevel gear or worm gear, is in Antriebsversbindung, z.
