Technical Field

The present invention relates to double-sided machines for industrial processing, for example machines for processing workpieces made of wood or other materials, such as for example tenoning, end-cutting, drilling or mortising machines or machines allowing a combination of two or more of the aforementioned or other functions.

Background

As is known, there are various machines for industrial processing of elements or workpieces made of different materials, which allow to give them a desired shape and are intended to shape them and then use them for specific purposes.

An example of such a machine is a tenoning machine for machining wooden workpieces, in particular for making tenons, which represent male coupling elements for producing furniture elements such as chairs, doors and windows.

These machines allow to mill the profile of one end of the inserted wooden element to make the desired tenon.

The tenon is then inserted into the female coupling element, the so-called mortise. Another way of coupling between the different elements is by means of pins, which, however, require butted and perforated ends into which pins can be inserted, these pins then being used for coupling with other parts machined in the same way.

The operations of making the tenon, end cutting and drilling or mortising are carried out by means of special tools which rotate and move at high speed on the piece to be machined to obtain the described joint.

Such machines for industrial machining of workpieces or elements generally comprise a support structure which extends in length along a longitudinal direction and which is at least partially closed so as to define an internal space of the machine in which components and in particular one or more machining heads equipped with tools for machining the workpiece are accommodated. Generally, the machine also comprises one or more work stations in which the workpieces are processed, and sometimes one or more parking stations in which the tools are parked when not in use. In particular, the work stations and the parking stations are arranged side by side along the longitudinal direction of the machine and generally alternate with each other on a first front facade of the machine parallel to the longitudinal direction. The machine also has movement and guide means which move and guide the machining head so that it reaches the aforementioned stations by translation.

The workstation typically includes a platform to position the workpiece to be machined; these platforms are arranged at contact points or openings formed on the front facade of the support structure to allow access from the outside to the interior of the machine. In this way, the operator can place the workpieces to be machined on the platform so that they project towards the interior of the machine, allowing machining by means of the tool.

These work stations thus allow to position the piece to be machined in such a way that the end to be machined is inserted inside the machine.

Usually, suitable clamping or pressing elements are also provided at the front elevation, which are adapted to hold the workpiece in place during machining of the workpiece.

However, the configuration of the pressing element and of the platform allows a workpiece to be machined only on the end of the workpiece, while it is often necessary to machine the same workpiece also on the other sides of the workpiece, i.e. also at the lateral surfaces.

For example, in the case where joints of workpieces for composing chairs or tables are to be made, machining of the side faces is required in addition to end cutting, drilling or mortising or tenoning of the ends of the workpieces, and more generally on all surfaces.

A possible solution to this drawback involves inserting the workpiece in a new machine arranged for machining on these further surfaces.

This solution implies high costs, since at least two machines have to be prepared.

Alternatively, the same machine is reconfigured from time to perform various processes. This is described in italian patent No. 0001395502 (application No. 102009901732383).

A disadvantage of this solution is that the reconfiguration is a complex operation which requires time and the intervention of a professional to be carried out. This results in a reduction in productivity and an increase in production cost.

Disclosure of Invention

The aim of the present invention is to eliminate the aforementioned drawbacks and, in particular, to conceive a machine for industrial machining that is capable of machining the head and sides of a workpiece without reconfiguration.

This and other objects according to the invention are achieved by making a double-sided machine for industrial processing as described in claim 1.

Further features of the double-sided machine for industrial processing are the subject of the dependent claims.

Detailed Description

With reference to the accompanying drawings, there is shown a double-sided machine for industrial processing, indicated as a whole with 10.

In the following description, particular reference will be made to the tenoning machine 10, which however does not exclude that the double-sided machine for industrial processing may be a different type of machine, such as for example an end-cutting, drilling or mortising machine or a machine combining multiple functions.

For the sake of simplicity, a cartesian plane is defined, visible in fig. 1, in which axis X is the length extension axis of machine 10, axis Y is the height extension axis of machine 10, and axis Z is the depth extension axis of machine 10.

As can be seen in fig. 1, the machine 10 comprises a supporting structure 1, the supporting structure 1 extending in length along a longitudinal direction X, the supporting structure 1 being adapted to support various functional components of the machine 10; the support structure 1 is at least partially enclosed to define a space inside the machine 10, covering the components and preventing the operator from accessing various moving and non-moving parts.

The machine 10 comprises in particular a front facade 2 and a rear facade 3.

Furthermore, the machine 10 comprises at least one front workstation 4 associated with the support structure 1 on a front facade 2 of the machine 10 and at least one rear workstation 6 associated with the support structure 1 on a rear facade 3 of the machine 10, wherein the at least one front workstation 4 and the at least one rear workstation 6 are arranged to allow machining on different ends or surfaces of the same workpiece.

The machine 10 further comprises at least one machining head 11, said at least one machining head 11 being associated with at least one spindle 7, 16, said at least one spindle 7, 16 being in turn associated with at least one tool 5, 5a, 15 a.

The tools 5, 5a, 15a may be replaced according to the specific machining to be performed.

The at least one machining head 11 is accommodated in the interior space and is movable at least in the longitudinal direction X such that the at least one machining head 11 can reach the at least one front work station 4 and the at least one rear work station 6.

For example, the at least one front station 4 is arranged to allow machining at a longitudinal end of the workpiece being machined, and the at least one rear station 6 is arranged to allow machining on a lateral surface of the workpiece being machined.

In this case, as shown in the figures, the at least one front station 4 comprises a first gripping element 22, the first gripping element 22 being adapted to hold the workpiece being machined in such a way as to place one of the ends in the working position. In the embodiment shown in fig. 1, the front facade of the machine 10 comprises two front stations 4, each of said two front stations 4 comprising a platform 20, the workpiece being placed on the platform 20, and the gripping elements 22 corresponding to pressing elements adapted to hold the workpiece in position on the platform 20.

The rear facade 3 is visible in fig. 3 and 4 according to two of its embodiments.

In a first embodiment shown in fig. 3, the rear facade 3 comprises a rear workstation 6, which rear workstation 6 comprises a gripping element 22 in the form of a gripper, which gripping element 22 is adapted to hold the workpiece being machined in such a way that one of the lateral surfaces is placed in the working position.

In another embodiment of fig. 4, the rear facade 3 comprises a rear workstation 6, which rear workstation 6 comprises a clamping element 22 in the form of a presser, which clamping element 22 holds the workpiece being machined stationary by working in conjunction with a platform 20 extending along the entire length of the rear workstation 6 in such a way that one of the lateral surfaces is placed in the working position.

The machining head 11 is in particular mounted on a column 8 movable on the guides 9 at least along a longitudinal direction X of extension of the machine 10, which allows the machining head 11, and therefore the at least one spindle 7, 16 and the respective tool 5, 5a, 15 and 15a, to move along the longitudinal direction X.

The at least one spindle 7, 16 is also movable on the upright along the vertical direction Y, and in addition and in particular also in depth along the direction Z, allowing the mobility of the respective tools 5, 5a, 15 and 15a required for the machining on both the front station 4 and the rear station 6.

This movability of the at least one main shaft 7, 16 can be transmitted by a set of oil hydraulic cylinders 17, 17a shown in fig. 5A, 5B, 5C, 6A, 6B and 6C or by other commands called NC-shafts.

In a first embodiment, not shown, the machine 10 comprises a single machining head 11, the single machining head 11 being associated with a single spindle 7, 16, which single spindle 7, 16 can in turn be associated with at least one tool 5, 5a, 15 and 15a, said at least one tool 5, 5a, 15 and 15a being adapted to machine the workpiece both when the workpiece is seated on said at least one front station 4 and when the workpiece is seated on said at least one rear station 6.

In this case, the machining head 11 can rotate on itself about a vertical or horizontal axis to position the tools 5, 5a, 15 and 15a on the desired work station. Alternatively, the spindles 7, 16 can be associated with a first tool 5, 15 adapted to machine the workpiece on the front workstation 4 and can be associated with a second tool 5a, 15a adapted to machine the workpiece on the rear workstation 6.

In a second embodiment shown in fig. 5A to 5C, the machining head 11 includes a first spindle 7 and a second spindle 16. The first spindle 7 can be associated with a single tool 5 adapted to machine the workpiece when it is seated on said at least one front station 4, while the second spindle 16 can be associated with a first tool 15 adapted to machine the workpiece when it is seated on said at least one front station 4 and with a second tool 15a adapted to machine the workpiece when it is seated on said rear station 6.

In a third embodiment of the machining head 11 shown in fig. 6A to 6C, the machining head 11 can be associated with two spindles 7, 16, each of the two spindles 7, 16 being associated with two respective tools 5, 5a, 15 and 15 a.

In this third embodiment, unlike the second embodiment, the first spindle 7 can also be associated with a first tool 5 adapted to machine the workpiece on the at least one front station 4 and with a second tool 5a adapted to machine the workpiece on the at least one rear station 6. In practice, the spindles 7 and 16 have two opposite engagement seats for the tools 5, 5a, 15 and 15 a.

In this case, one or both of the two spindles 7 and 16 will move the tool 5 or 15 associated with the front facade 2 of the machine 10 to machine the workpiece on the front workstation 4 or move the tool 5a or 15a associated with the rear facade 3 of the machine 10 to machine the workpiece on the rear workstation 6 as required.

In a fourth embodiment, not shown, the machining head 11 comprises a first spindle 7 associable with a first tool 5 adapted to machine a workpiece on said at least one front station 4 and a second spindle 16 associable with a second tool 15a adapted to machine a workpiece on said at least one rear station 6.

In this case, both spindles 7 and 16 may be associated with a single upright 8, thus performing machining on one or the other part of machine 10.

In a fifth embodiment, not shown, the machine 10 comprises two uprights 8, each of said two uprights 8 being movable on a respective guide 9, so that each of two machining heads 11 is movable on a respective guide 9. In this case, each machining head 11 of the two machining heads 11 is associated with at least one spindle 7, 16, wherein the first spindle 7 is adapted at least to machine the workpiece on the at least one front workstation 4 by means of the tool 5 and the second spindle 16 is adapted at least to machine the workpiece on the at least one rear workstation 6 by means of the tool 15 a.

Both spindles 7, 16 can independently machine workpieces associated with the respective work stations.

With reference to the embodiment of the machine 10 comprising the machining head 11 shown in fig. 5A to 5C, the operation of the double-sided machine 10 for industrial machining is as follows, it being understood that similar descriptions apply to the double-sided machine 10 according to other embodiments.

When it is desired to machine a workpiece in its longitudinal end portion, it is inserted into the at least one front station 4 by means of a suitable presser grip element 22 and by means of the table 20. In this case, the workpiece is inserted transversely to the longitudinal direction of the machine 10.

At this point, the first spindle 7 is actuated, the first spindle 7 in turn actuates the tool 5, and the first spindle 7 guides the tool 5 during machining of the aforementioned end portion of the workpiece. The machining takes place in particular by means of the movability of the spindle 7 on the upright 8 along at least two directions X, Y along the cartesian plane. Once the tenoning or end-cutting machining by means of the tool 5 by means of the first spindle 7 has been completed, a second spindle 16, which second spindle 16 can have, in addition to the movements in the directions X and Y, also the movement in the direction Z carried out by means of a set of cylinders 17, can be put into operation in order to make (execution) a hole or mortise on the same end of the workpiece by means of the tool 15.

Once the machining of the end portions of the one or more workpieces has been completed, the machining of the lateral portions of the one or more workpieces is continued as required, whereby the machining on the rear work station 6 is carried out.

For example, a tenon is made on the end portion of the workpiece by the front work station 4, while the rear work station 6 is used for finishing the lateral faces of the workpiece.

The workpiece is then inserted on the rear work station 6 along a lateral portion of the workpiece, in particular by means of gripper-type gripping elements 22 or by means of a combination of presser gripping elements 22 and by means of the platform 20, in a manner so as to be substantially parallel to the longitudinal direction X of the machine 10.

At this point, the second spindle 16 actuates the second tool 15a facing the at least one rear station 6 to enable machining of the lateral portion of the inserted workpiece.

In case the first spindle 7 can also be associated with the second tool 5a and is given the possibility of being moved along the direction Z, for example by means of a set of cylinders 17a, the first spindle 7 will also be able to bring the second tool 5a at the rear work station 6.

Advantageously, when the double-sided machine 10 comprises one of said two spindles 7 with two tool holder ends, there is also the possibility of machining the end of one workpiece and the lateral portion of the other workpiece.

The characteristics of the machine of the invention and the advantages thereof are evident from the above description.

Finally, it is clear that the device thus conceived is susceptible of numerous modifications and variations, all of which fall within the same inventive concept; moreover, all the details may be replaced with technically equivalent elements. In practice, the materials used, as well as the dimensions, may be of any type according to the technical requirements.
