Description

Optimized manufacturing method and system for lean production in panel production line of furniture industry

Technical Field

The present application relates to a method for the optimized management of panel production lines in the furniture industry and to a device and a work line for implementing the method.

Background

By lean manufacturing or lean production is meant the theory of industrial transformation derived from toyota insights (toyota automotive production system-TPS-from the japanese automotive manufacturers, where it is considered, tested and adopted), the objective of the production organisation method based on the idea of "doing more with less investment" (i.e. using the available resources in the most rational way possible) is to increase productivity with the aim of minimizing the following waste: redundant actions (limiting actions that do not generate value), redundant actions (limiting movement to materials that are farther away from the point of view of use), redundant defects (limiting waste and processing duplication), redundant inventory (limiting purchase and production of redundant material relative to that required for subsequent processing), redundant production (limiting production more than required for subsequent processing or customers or limiting inventory in other ways), redundant waiting (limiting non-production mode usage time), and redundant shipping (limiting movement to materials that do not need to generate value).

The criteria deriving from these redundant minimization principles and constituting the principle processes for relative implementation (more precisely, aimed at the relative implementation) are proximity criteria or relative criteria in component processing or machining operations, which are combined in several points of view and are crossed according to the technical objective added with respect to the different optimization options of the industrial sector and of the specific plant.

In the sector of the production of the furniture industry, the application of the lean principles of the industrial transformation theory can find a rich scope, considering the homogeneity of the parts used to constitute the final product, basically and mainly wooden panels or wooden substitutes, while in the other sector, considering the various forms of the mechanical industry, making the parts to be produced and/or assembled lack consistency, the transformation of the simplification criterion being more complex to implement.

In the aforementioned special sector for the industrial production of furniture, the proximity standards can be combined in the following point of view:

the sources are close: the standard of joining (bind) elements according to a standard derived from the same type of sheet material, where this is used to indicate a sheet material of commercial size from which the panels constituting the product are cut;

order approaching: -combining a plurality of elements or a set of elements according to criteria belonging to the same order, wherein, in contrast, the order is constituted by the elements defined by the order in their entirety and is organized according to a plurality of proximity criteria;

the kit approaches: combining a plurality of elements according to a standard belonging to the same kit;

the sources are close: the criterion of bonding a plurality of elements according to belonging to the same material or to a semi-finished product source;

the intended use is close to: standards that incorporate multiple orders, kits and components to be directed to the same line gate simultaneously;

the treatment is as follows: according to the criterion that a plurality of elements must be combined across the same transformation path;

reference proximity: the criterion for joining a plurality of elements, such as main panel faces, perimeter faces, sides, edges, etc., depends on the criterion that the same or similar elements constituting the product must be interfered with.

These minimization principles and industrial transformation theoretical standards will be referred to as transformations, which can be divided into basically three types, according to the action performed on the element to be processed, assuming that in any manufacturing process the material will undergo a sequence of transformations:

spatial transformation: moving material from one location to another;

and (3) class conversion: a process of changing the characteristics and/or shape of an element, particularly due to and with reference to the furniture industry production sector, which can be carried out and summed up for: treatment approaches, e.g., all drilling operations, all edging operations, etc.; reference proximity, e.g., major faces, perimeter faces, dimensions, edges, etc. of the panel;

time conversion: operations to change the sequential order of elements, e.g. buffering, etc.

Disclosure of Invention

In this context, the main object of the present invention is to provide a novel and practical method, suitable for generating a series of transformations, which can start with the following steps: the panels are separated into panels by a surface optimizer and the panels are randomly moved apart, obtaining systematic unloading of the panels in the order and kit, minimizing all inefficient operations.

It is a further object of the present invention to provide an apparatus and a work line for carrying out the aforementioned method, which minimize or reduce the relevant dimensions.

Another purpose of the present invention is to achieve the aforementioned objects by means of a method and a device of relative implementation that can be versatile and multivalent as regards the type of furniture to be produced.

A further object of the present invention is to achieve the aforementioned objects by means of a method and a device of relative implementation which are simple and efficient, safe to use and relatively inexpensive in view of the results actually obtained.

Also disclosed are a device and a work line for carrying out the method according to the invention, comprising at least one sorting complex 20, in which a production line is formed, which is constituted by at least one process-sorting unit 20, which process-sorting unit 20 comprises at least one chambered container or vector-matrix 22, which container or vector-matrix 22 is translatable with respect to the ground, is adapted to hold a plurality of panels 1, which panels 1 are arranged in a vertical orientation laterally in parallel channels 24 and sorted by rows and columns, can be inserted and extracted randomly from the top and from the sides, wherein the random arrangement order of the panels 1 or the method of ordering, loading and unloading the panels 1 and the translation of the chambered or vector-matrix 22 with respect to the ground are determined by a computer logic circuit which optimizes the random or trend random loading of the panels 1 upstream and the downstream random loading according to the purpose of the batch and/or the production line Or a combination of random demand on a part of the production line and tendency to organize the unloading for groups of panels 1.

Detailed Description

Static description of the examples

Description of the system in its entirety schematically represented in the embodiment of fig. 1, with reference to the attached drawings, the nesting device represented in detail in fig. 2 will be indicated in its entirety by 10, wherein the commercial panel sheet on the conveyor line 11, which is laid on the device 12 for carrying out the nesting process, or in order to maximize the utilization efficiency of the semi-finished product and obtain panels 1 of various sizes, determined by the calculation logic of the method, for determining all the panels constituting the furniture that can be obtained through the production line, is represented for example in fig. 3.

In the nesting device 10, it is also possible to envisage a group of operators (not shown) for performing some operations, predicting and then completing some values required in the actual downstream finishing unit 30, which finishing unit 30 is dedicated to processing the parts.

In addition, at the exit of the nesting device 10, it should be considered that there are arranged means, not shown, and an applicator for applying to the panel 1 a sticker with a bar code, or preferably an integrated chip (chip, RFID-radio frequency identification, transponder), containing a code of all the relevant source, destination and position identification elements, for traceable purposes, as processed by the computer logic implementing the method.

A handling-sorting unit, indicated as a whole with 20, which is shown in detail in figure 4, is constituted by a track circuit 21 on which two carriages, indicated as a whole with 22 respectively, slide, comprising a planar frame 23, the planar frame 23 being constituted by a plurality of pockets 24 or parallel channel-like cells.

The carriages 22 operate on the loop 21 according to their function-optimized computer logic which inserts parameters relating to the loading method and time:

starting from the loading position of the conveyor 11 for the nesting device 10 (shown in fig. 5), in which position a suspension handling device 25 is arranged, in the embodiment shown of the cartesian type, which selectively drives, for example, an anthropomorphic robot, for seizing-translating-guiding the panels 1 brought to the plane by the conveyor 11 of the nesting device 10 in a sequence determined by the computer logic of the implementation method and according to criteria determined by the computer logic (preferably a replica arrangement sequence) and inserting them vertically into the pockets 24 or parallel channel-like cells of the rack 23, wherein the panels 1 are positioned by scaling dimensions, which presuppose the stacking structure to be described later.

In the unloading position (shown in fig. 6), the processing and finishing unit 30, better described later, and therefore the relative conveyor 31, are fed, where extractor devices 26 are arranged, which extractor devices 26 are of the pusher and chute type, for orienting single or multiple panels 1 arranged in rows, in a sequence determined by the computer logic of the implementation method and according to the standard engagement-translation-determined by the computer logic, which panels 1 are concentrated in preferably scaled groups 2 (considering beforehand the structure of the stacks 2, described later), in the pockets 24 or parallel channel-like cells of the rack 23.

The treatment and finishing unit of the panel 1 (shown in detail in figure 8) is indicated as a whole with 30, by means of which the panel 1 is subjected, in a known manner, to drilling operations, grinding operations and edging operations and to finishing them in order to prepare them for any other matter required for assembly, by means of an operating group of known type (the introduction of which will be considered superfluous here).

A unit for stacking panels 1, shown in detail in figure 9, is indicated as a whole with 40, which picks up the panels 1 exiting from the processing and finishing unit 30 and arranges them in a decreasing order so as to form a scaled stack 2, as shown by way of example in figure 10, preferably reproducing the scaling arrangement order previously formed in the carriages 22 and in the pockets 24 or parallel channel-like cells of the rack 23 of the processing-sorting unit 20.

Finally, the unit for storing stacks 2 of panels 1 (shown in detail in fig. 9), in which the stacks 2 are arranged on racks 51, is globally indicated with 50, systematically concentrated in an order determined by the computer logic implementing the method and according to criteria determined by the computer logic (to be described later).

Dynamic description of the embodiments

Having completed a static description of a preferred embodiment of the device for the optimized management of panel production lines in the furniture industry according to the present invention, the following is a dynamic description or a related operation, namely a method for the optimized management of panel production lines according to the present invention in the furniture industry with respect to the device illustrated and the working line of the related embodiment:

the preliminary step is to obtain, by means of the management software, a different basis from the data coding, concerning:

a type of furniture part, a color of a plurality of furniture types, a size of each furniture type, a size of a panel component of each furniture type, a total length of a panel component of each furniture type;

an order, an identification of individual parts of furniture in each order, a color of a type of furniture in each order, a quantity of each type of furniture in each order, a priority of delivery deadline for the order;

the function and functionality of the management system or production line, for the purposes of the description of the present invention, will be related in particular to the assignment of an identification code to a panel 1 determined by the nesting process 12, the positioning of the carriage 22 in the process-sorting unit 20 in comparison with its translation capacity with respect to the ground, and the number and size of the pockets or parallel channel-like cells 24 of the rack 23 of the carriage 22.

In processing these data and any other data fed back from the device during the operation of the management system, which indicates the processing during execution and completion, the management software performs a production start, preferably organized for order access (according to the standard for joining a plurality of elements or sets of elements belonging to the same order), according to the characteristics of the panels leaving the nesting device 10 and according to the progression and stage of filling pockets 24 or parallel channel-like cells in the rack 23 of the carriage 22 of the processing-sorting unit 20.

In the aforementioned preferred order proximity criteria, the start of production is organized in view of the following criteria:

source proximity (according to the standard of combining a plurality of elements belonging to the same material or to a semi-finished product source, in particular the type of sheet material, with respect to thickness, colour);

kit proximity (according to a standard for joining multiple components belonging to the same kit);

proximity of intended use (in combination with criteria for multiple orders, kits and components to be directed to the same line gate at the same time);

if desired, the process approaches (based on the criteria that multiple elements must be joined across the same transformation path).

The production start operation (mainly for the nested device 10) generated by the management software on the management system is executed and recorded in a serial manner as the working sequence for the various devices and machines of the production line, all corresponding to their processing stage (update start state).

In this context, the nesting device 10 loads the required sheet material and generates the starting (lauch) panel 1, updating the management and manager for each released part, which releases the individual marking for identification and traceability by means of a tag with a bar code and/or an integrated chip (chip, RFID-RFID, transponder).

When determining the optimal nesting treatment of the individual panels, they can also carry out treatment operations, such as drilling the surface, so as to anticipate its subsequent treatment and the operation of the finishing unit 30.

When detached from the nesting device 10, the panel 1 is gripped by a handling-sorting unit 20, which handling-sorting unit 20 constitutes a device for implementing the method according to the invention.

The panels 1 exiting from the nesting devices 10, arranged on a plane by their larger surface, are collected on a conveyor line 11, raised individually by handling-gripping-orienting devices 25 (of the cartesian type in the illustrated embodiment, or alternatively of the anthropomorphic type), conveyed and dropped from the top, optionally vertically oriented laterally, housed vertically in pockets or adjacent horizontal parallel channel-like cells 24 of the frame 23 of two carriages 22, which carriages 22 are optionally movable on a closed circuit or turret 21.

Considering the movement of the carriage 22, the suspended handling-gripping-guiding means 25 reach all the marking points (topographiy points) of the carriage 22 in order to perform these operations: grasping the panel 1, orienting, optionally inserting in a vertical position, inside the cells 24, releasing into them so as to form parallel rows.

The operations of gripping the panel 1, orienting, selectively introducing in a vertical position inside the cells 24, releasing into them so as to form parallel rows, and the movement of the carriage 22 are thus carried out by commands of the management system so as to duplicate the order arrangement, within each order the single pieces constituting the furniture are grouped, so that within each order the sequence of sets of the parts constituting the furniture is sorted according to the length of the panel 1.

In other words, a preferred use of the method and device according to the invention consists in generating directly downstream of the cutting station a determinate arrangement of orders and of the order contents, which will be maintained during the processing and subsequently during the packaging by vertically housing the panels 1 laterally arranged, vertically oriented, in parallel channel-like cells 24, with the aim of reducing the planar space and sorting them by rows and columns, separating them by orders, selecting and sorting them by size in a scaled configuration within the orders, as programmed by an electronic logic circuit that obtains all the method data.

Without interruption, but through the flow of tissue of the kit and the orders, they are taken out of the panels 1 at the end of the processing and finishing unit 30 by the extractor 26, preferably by being pushed sideways in a linear direction towards the cell 24, then tilted towards one or more processing operating units 30 on the plane of the feeding device 31, in the same translation on the circuit 21 of the carriage 22, in the same grouped orders previously determined on the frame 23 of the carriage 22.

Upon arrival at the processing and finishing operating units (i.e. edging and/or structural drilling operations), the panels 1 are preferably processed in time synchronism with the supply upstream and the discharge downstream, in the same sequence of arrival and release orders (possibly on a plurality of work lines).

The panels 1 are therefore unloaded at the stacking unit 40, maintaining the same sequential order in the scaled stacks 2 of at least one panel 1 (with a length decreasing from the bottom to the top), which comprises the complete kit of parts constituting the pieces of furniture, duplicating the same order, albeit in a vertical orientation therein and in a superimposed orientation on the plane of the panels, for the rows and columns allocated to the panels 1 within the housing 23 of the carriage 22.

The stack thus formed or reconstituted is therefore gripped by the storage unit 50 and arranged on the frame 51 for delivery.

In another illustrative method, a method according to the present invention is used for:

style transformation, forming color or starting waveform: to generate the start of production, multiple orders combined by source access are combined, followed by nesting of panels, the invalidation of the start of production will be according to the following criteria: delivery priority, performance of cutting plane and amount of panels obtained, nesting, random departure of parts, marking each panel for traceability.

Time-shifting, randomly picking up horizontally arranged panels, relative arrangement, orientation and alignment, and forming group translations, and forming groups, preferably vertically by order arrangement, in each order for grouping the parts constituting each part of the furniture, so that in each order, sequential orders of the kit can be finally unloaded into layers of reduced length and with such orders.

Style change, finishing panels in the same sequential order, and drilling, grinding, and possibly edging operations.

Time shifting, keeping the same sequential order when finally unloaded on stacked pallets into layers of reduced length; for two or more depth orders (depth orders), the order should contain a plurality of parts of the furniture, and for each depth order, the panels can also be sorted into parallel stacks.

Alternative embodiments

Obviously, in a further alternative embodiment (according to the above described embodiment and to the following claims, still falling within the same conceptual solution), the method and system for the optimal management of panel production lines in the furniture industry according to the present invention can be implemented by means of equivalent technical and implementation solutions, or also provided with complementary solutions, the same conditions of all the methods applied to the relative process steps can be varied so as to suit the purpose.

Advances in the invention

As it is clear from the preceding description of preferred embodiments, and as also described above with reference to some variant embodiments, the method and system for the optimal management of the panel production line in the furniture industry according to the present invention provide the advantage of reaching preset aims and even other ones:

in fact, a novel and practical method is provided for generating a series of transformations starting from the step of dividing the panel into panels, with surface optimization and out of order of the panels, performing systematic unloading of orders and suites, minimizing all negative (passive) operations;

furthermore, a working line is provided, the relevant dimensions of which are reduced as much as possible, for carrying out the method described herein.

In particular, the structure of the carriages movable with respect to the ground has cells that can be loaded and unloaded from the top, and by sliding them out from the sides, constitute an extremely flexible store for the distribution panels, and are configured to minimize the logical space and to exploit the force of gravity for filling and retaining groups of panels.

The foregoing concept of a system part for executing orders is capable of holding orders until the end of an operational cycle with essentially a single time shift, or with minimal adverse operation.
