Definitions
- the invention relates to a device for feeding boards according to the preamble of claim 1.
- the boards are after scanning on a feeder in the form of a wide roller conveyor with cam chain or a wide conveyor belt with overhead fan transport aligned on a front side passed a subsequent transverse transport unit. At this point, the boards are taken individually from the transverse transport unit and kept isolated by means of so-called flow latches.
- Flow pawls are pneumatically controlled stoppers operated by a device control signal. This signal is generated by one or more photocells when the board is in the correct position.
- the transverse transport unit becomes pivoted so that the boards can be transferred to a subsequent feed level, where they are fed to the chop saw. Often two superimposed loading levels are provided, each associated with a chop saw.
- a second transverse transport unit which is pivotable and can be controlled with the further feed levels, which are associated with further chop saws.
- this device is susceptible to interference when tracking the boards. It happens that a board is fed to a chop saw and the electronic board data (cut list) of another board of the control of the chop saw are transmitted. This then leads to false performance results until the error in the feed motion is detected by control mechanisms and the device is stopped. Thereafter, the device must be emptied empty or driven empty, which interferes with the production flow and has a performance-reducing effect.
- a feeder a transverse transport unit is connected downstream, which consists of two cascade conveyors arranged one above the other.
- Each cascade conveyor has a front conveyor belt and a downstream rear conveyor.
- the front conveyor belts can be adjusted about an axis transverse to the feed direction between two positions so that the boards are transported by the feeder selectively on the upper or the lower front conveyor belt.
- a stop is provided in each case, on which the boards accrue.
- wood-edged board material is transported by means of carriers over a longitudinal conveyor.
- the drivers are lowered down so that they can be transported further under the longitudinal conveyor.
- the invention has the object of providing the generic device in such a way that the boards can be tracked properly during their transport to the chop saw and present at the chop saw the boards and the associated cut lists or board data.
- the boards are reliably distributed to the feeder by means of the transverse transport unit to the desired loading level, without the need for photocells and other sensors for tracking the boards.
- a stop is set in the transport path of the boards, at which the boards coming from the feeding device come to rest. As long as the transverse transport unit is adjusted to the new loading level, the boards remain on the transverse transport unit.
- This design ensures that the boards are reliably fed to the predetermined feed levels and the predetermined chop saws. Since the pivot axis of the transverse conveyor unit lies in the transfer region of the boards from the feed device to the transverse transport unit, the boards can be fed further by the feed unit during the adjustment of the transverse transport unit. The supplied boards run on the stop, which can be moved to the other end of the transverse transport unit. If this position is reached, the transverse transport unit can be pivoted about the pivot axis to a new loading level.
- the device has a feeding device 1 for boards 2, which are fed to a feed device downstream of the transverse transport unit 3.
- the feeder 1 may be formed as a wide roller conveyor with cam chain or as a broad conveyor belt.
- the feeder 1 is a wide roller conveyor, the transversely to its transport direction 4 lying flat spacers 5, the adjacent boards 2 separate from each other.
- the wide roller conveyor is driven.
- the boards 2 are conveyed in their longitudinal direction between the spacers 5 by means of a preceding conveyor unit (not shown).
- the transport unit is formed for example by feed rollers on the boards 2 and transport them in their longitudinal direction on the feeder 1.
- the boards 2 have been previously scanned by so-called continuous scanners, which are arranged stationary and detect the data of the boards 2 in a known manner. For the recorded board data, a data record is created, by means of which the device (not shown) cut-off saws the boards 2 saw.
- the transverse transport unit 3 In the last compartment 6 of the feeder 1 before the transfer to the transverse transport unit 3 is by means of a sensor, preferably a photocell (not shown), checked whether the boards 2 are aligned with its end face 7 with respect to a frontal zero edge. Parallel to the transport of the boards 2, the associated data records are transmitted to the respective saws. The boards 2 are transferred to the transverse transport unit 3, which is set according to the cut list with respect to the feeder 1. As it turned out Fig. 1 results, the transverse transport unit 3 can be adjusted to an axis transverse to the transport direction 4 axis 8 in different positions. Exemplary are in Fig. 1 four pivotal positions I to IV of the transverse transport unit 3 shown.
- the pivot axis 8 is located in the transfer area 9 of the feeder 1 to the transverse transport unit 3.
- the woods 2 (not shown) feed levels are passed, which feed the boards to the downstream chop saws.
- the transverse transport unit 3 can be pivoted into four different inclination positions. Each of these inclination positions is assigned in each case a chop saw, in which the woods 2 are cut according to the records.
- the transverse transport unit 3 consists of parallel adjacent, endlessly circulating belt 10, with which the boards 2 in the transport direction 11 (FIG. Fig. 1 ) be transported.
- a cam chain is provided which has one or more cams 12.
- the drive of the cam chain with the cam 12 is advantageously carried out by means a servomotor.
- the drive of the cam chain can also be done by means of frequency converter or three-phase motor with brake.
- a motor drive preferably a servomotor, is used for the stroke adjustment of the transverse transport unit 3.
- transverse transport unit 3 By means of pneumatic or hydraulic power units.
- the transport belt 10 of the transverse transport unit 3 with the associated deflection rollers are mounted in a common (not shown) frame, which is adjusted by means of the drive in height.
- corresponding loading planes to which the woods of the respective chop saw are fed, adjoin the corresponding end of the transverse transport unit facing away from the feed device 1.
- Fig. 3 Based on Fig. 3 the function of the cam chain is explained. They each have two cams 12 which project beyond the belts 10 of the transverse transport unit 3. First, the boards 2 are transferred from the feeder 1 of the transverse transport unit 3, one of the in Fig. 1 shown pivoting positions I to IV occupies. The cams 12 are corresponding to the middle figure of Fig. 3 arranged. If enough boards 2 have been successively fed to the corresponding loading level and if the loading level is to be changed, the cam chains are driven such that the cam 12 is moved at the rear end of the transverse transport unit 3 in the transport direction 11 in the transition area 9 from the feed device 1 to the transverse transport unit 3 into the transport path the boards 2 passes. The trajectory of the cam 12 is in Fig. 2 shown.
- the drives of the feeder 1 and the cam chain are coordinated so that the cam 12, seen in the direction of the axis 8, emerges in the region of the last spacer 5 before the deflection of the support plane 13 of the feeder 1.
- the position of the cam 12 according to Fig. 2 corresponds to the figure below Fig. 3 ,
- the other cam 12 of each cam chain is located in the region of the lower run of the belt 10 the feeder 1 coming boards 2 in succession.
- the boards 2 located in the transport direction 11 in front of the cam 12 can still be transported further to the coating plane.
- the cam 12 runs with the belt 10 until it reaches the front in the transport direction 11 end of the transverse transport unit 3 (upper figure in Fig. 3 ).
- the camshafts and thus the cams 12 are stopped and the transverse transport unit 3 is pivoted about the axis 8 in a new position to provide another loading level with the boards 2.
- the cam 12 of the cam chains located in the transport direction 11 lies in the lower run area of the belts 10, so that the boards 2 continue to be conveyed by the feed device 1 onto the transverse transport unit 3.
- the boards 2 are collected lying on the stationary cam 12 in this way.
- the cam chains are driven and the cam 12 is moved into the region of the lower run of the belts 10.
- the boards 2 are thereby released and reach the new loading level.
- the position of the cam 12 immediately after release of the boards 2 is in the middle figure of Fig. 3 shown.
- the other cams 12 are in a position that they do not hinder the feeding of the boards 2 from the feeder 1 to the transverse transport unit 3.
- This position of the cams 12 corresponds to the basic position of the cam chains, so that the belts 10 of the transverse transport unit 3 can take over the boards 2 from the feed device 1 and transfer them to the loading plane.
- the left cam 12 is shown, which by driving the corresponding cam chain in the transport direction 11 in the direction of its locking position (upper illustration in FIG Fig. 3 ) is transported.
- the boards 2 which are further conveyed by the feed direction 1, run on their rear side.
- the cam 12 has the locking position corresponding to the upper figure of Fig.
- the drive of the cam chains is stopped and now the transverse transport unit 3 is pivoted about the axis 8 in a new position to provide another loading level with the boards 2. If the transverse transport unit 3 has reached the new pivot position, the cam chains driven and accordingly the cam 12 is moved to the release position (middle illustration of Fig. 3 ), so that the boards 2 can be fed to a new loading level.

Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Zuführen von Brettern nach dem Oberbegriff des Anspruches 1.The invention relates to a device for feeding boards according to the preamble of
Bei der Holzverarbeitung ist es bekannt, zu sägende Bretter bzw. Hölzer zunächst mittels einer stationären Scannereinheit im Durchlaufverfahren zu scannen und auf diese Weise beispielsweise Fehler in den Brettern zu erfassen, die bei der weiteren Verarbeitung entfernt werden müssen. Die von der Scannereinheit erfassten Brettdaten werden softwaremäßig optimiert und pro Brett eine Schnittliste errechnet. Anhand der Schnittliste wird das abgescannte Brett von Kappsägen bearbeitet. Die Bretter werden nach dem Scanvorgang von einer Mechanisierungseinrichtung übernommen, wobei an einer Übergabestelle dem jeweiligen Brett die zugehörige Schnittliste zugeordnet wird. Die Bretter mit den zugeordneten Schnittlisten werden einer oder mehreren Kappsägen zugeführt. Die Bretter werden nach dem Scanvorgang auf einer Zuführeinrichtung in Form einer Breitrollenbahn mit Nockenkette oder einem Breittransportband mit oben liegendem Fächertransport an einer Stirnseite ausgerichtet einer nachfolgenden Quertransporteinheit übergeben. An dieser Stelle werden die Bretter einzeln von der Quertransporteinheit übernommen und mittels sogenannter Fließklinken vereinzelt gehalten. Fließklinken sind pneumatisch angesteuerte Stopperreihen, die durch ein Signal der Vorrichtungssteuerung betätigt werden. Dieses Signal wird von einer oder mehreren Fotozellen dann erzeugt, wenn das Brett in der richtigen Position liegt. Nach einer bestimmten Anzahl von Brettern, vorzugsweise zwischen fünf und zehn Brettern, wird die Quertransporteinheit so geschwenkt, dass die Bretter auf eine nachfolgende Beschickungsebene übergeben werden können, auf der sie der Kappsäge zugeführt werden. Häufig sind zwei übereinander angeordnete Beschickungsebenen vorgesehen, denen jeweils eine Kappsäge zugeordnet ist. Es ist auch möglich, nachgeschaltet eine zweite Quertransporteinheit vorzusehen, die schwenkbar ist und mit der weitere Beschickungsebenen angesteuert werden können, denen weitere Kappsägen zugeordnet sind. Die Kontrolle über die Position der Bretter auf den Quertransporteinheiten und die Verteilung der Bretter auf die jeweiligen Beschickungsebenen erfolgt mittels Fotozellen und der Steuerung der Vorrichtung. Diese Vorrichtung ist allerdings störanfällig bei der Verfolgung der Bretter. Es kommt vor, dass ein Brett einer Kappsäge zugeführt wird und die elektronischen Brettdaten (Schnittliste) eines anderen Brettes der Steuerung der Kappsäge übertragen werden. Dies führt dann zu falschen Kappergebnissen, bis der Fehler in der Zuführbewegung durch Kontrollmechanismen bemerkt und die Vorrichtung angehalten wird. Danach muss die Vorrichtung leer geräumt oder leer gefahren werden, was den Produktionsfluss stört und sich leistungsmindernd auswirkt.In woodworking, it is known to first scan boards or wood to be sawn by means of a stationary scanner unit in a continuous process and in this way to detect, for example, faults in the boards, which must be removed during further processing. The board data recorded by the scanner unit are optimized by software and a cutting list is calculated per board. Based on the cut list, the scanned board is edited by cross cut saws. The boards are taken over after the scanning process by a mechanization device, wherein the relevant cutting list is assigned to the relevant board at a transfer point. The boards with the assigned cut lists are fed to one or more chop saws. The boards are after scanning on a feeder in the form of a wide roller conveyor with cam chain or a wide conveyor belt with overhead fan transport aligned on a front side passed a subsequent transverse transport unit. At this point, the boards are taken individually from the transverse transport unit and kept isolated by means of so-called flow latches. Flow pawls are pneumatically controlled stoppers operated by a device control signal. This signal is generated by one or more photocells when the board is in the correct position. After a certain number of boards, preferably between five and ten boards, the transverse transport unit becomes pivoted so that the boards can be transferred to a subsequent feed level, where they are fed to the chop saw. Often two superimposed loading levels are provided, each associated with a chop saw. It is also possible, provided downstream, to provide a second transverse transport unit, which is pivotable and can be controlled with the further feed levels, which are associated with further chop saws. The control of the position of the boards on the transverse transport units and the distribution of the boards on the respective loading levels by means of photocells and the control of the device. However, this device is susceptible to interference when tracking the boards. It happens that a board is fed to a chop saw and the electronic board data (cut list) of another board of the control of the chop saw are transmitted. This then leads to false performance results until the error in the feed motion is detected by control mechanisms and the device is stopped. Thereafter, the device must be emptied empty or driven empty, which interferes with the production flow and has a performance-reducing effect.

Bei einer anderen bekannten Vorrichtung (
Der Erfindung liegt die Aufgabe zugrunde, die gattungsgemäße Vorrichtung so auszubilden, dass die Bretter bei ihrem Transport zur Kappsäge einwandfrei verfolgt werden können und an der Kappsäge die Bretter und die zugehörigen Schnittlisten bzw. Brettdaten vorliegen.The invention has the object of providing the generic device in such a way that the boards can be tracked properly during their transport to the chop saw and present at the chop saw the boards and the associated cut lists or board data.
Diese Aufgabe wird bei der gattungsgemäßen Vorrichtung erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruches 1 gelöst.This object is achieved in the generic device according to the invention with the characterizing features of
Bei der erfindungsgemäßen Vorrichtung werden die Bretter nach der Zuführeinrichtung mit Hilfe der Quertransporteinheit zuverlässig auf die gewünschte Beschickungsebene verteilt, ohne dass Fotozellen und andere Sensoren zur Verfolgung der Bretter notwendig sind. Soll die Quertransporteinheit auf eine andere Beschickungsebene eingestellt werden, wird in den Transportweg der Bretter ein Anschlag verstellt, an dem die von der Zuführeinrichtung kommenden Bretter zur Anlage kommen. Solange die Quertransporteinheit auf die neue Beschickungsebene verstellt wird, bleiben die Bretter auf der Quertransporteinheit. Diese Ausbildung stellt sicher, dass die Bretter zuverlässig den vorbestimmten Beschickungsebenen und den vorbestimmten Kappsägen zugeführt werden. Da die Schwenkachse der Querfördereinheit im Übergabebereich der Bretter von der Zuführeinrichtung zur Quertransporteinheit liegt, können die Bretter während des Verstellens der Quertransporteinheit von der Zuführeinheit weiter zugeführt werden. Die zugeführten Bretter laufen auf den Anschlag auf, der bis zum anderen Ende der Quertransporteinheit bewegt werden kann. Ist diese Stellung erreicht, lässt sich die Quertransporteinheit um die Schwenkachse auf eine neue Beschickungsebene verschwenken.In the apparatus according to the invention, the boards are reliably distributed to the feeder by means of the transverse transport unit to the desired loading level, without the need for photocells and other sensors for tracking the boards. If the transverse transport unit is to be set to another loading level, a stop is set in the transport path of the boards, at which the boards coming from the feeding device come to rest. As long as the transverse transport unit is adjusted to the new loading level, the boards remain on the transverse transport unit. This design ensures that the boards are reliably fed to the predetermined feed levels and the predetermined chop saws. Since the pivot axis of the transverse conveyor unit lies in the transfer region of the boards from the feed device to the transverse transport unit, the boards can be fed further by the feed unit during the adjustment of the transverse transport unit. The supplied boards run on the stop, which can be moved to the other end of the transverse transport unit. If this position is reached, the transverse transport unit can be pivoted about the pivot axis to a new loading level.
