Definitions

the invention relates to a device for providing strip-like elements according to the preamble of claim 1.
first solid or lightweight panels Z. B. chipboard or honeycomb panels are often produced, which are subsequently provided on their front sides with a strip or strip-shaped edge material.
the edge material is glued or otherwise attached in an edge applicator machine, which may be part of a continuous processing equipment.
the edge application machine must always be supplied with edge material in sufficient quantities.
DE 30 03 555 A1 and DE 29 52 011 C2 each disclose a generic device for feeding strip material to an edge banding machine.
a stack of edge material is pressed by means of a slider to a transport roller, which conveys individual edge material strips to a Kantenanleimmaschine. Once all strips of the stack are carried out, the machine operation interrupted, the slide is pushed back and new strips are inserted.
the invention is based on the idea to decouple the insertion of the strip-shaped elements or the formation of a corresponding stack from the insertion of the strip-shaped elements between the supply device and feed device spatially and temporally.
the invention provides that the device has a supply device for automatically feeding an element stack between the supply device and the feed device.
the device according to the invention enables a reduction of the stack sizes without loss of performance.
the reduced stack sizes, where a "stack" may possibly include only a strip-shaped element, resulting in lower and more constant pressure forces within the device, whereby significant sources of interference for the operation of the device are eliminated.
the supply device has at least one endless element which has a plurality of stop elements.
the supply device has at least one endless element which has a plurality of stop elements.
the endless element in the context of the present invention can be, for example, a chain, a rope, a belt or the like.
the embodiment of the supply device has proven to be a cam belt with stop cams.
the mutual distance of the stop elements or stop cam is adjustable, so that the supply device to varying stack sizes or dimensions of the strip-shaped elements can be adjusted.
the stop elements have compensation means which allow the insertion of element stacks of different thickness between adjacent stop elements.
the compensating means may preferably be spring means, such as leaf springs or the like, which are provided on at least one side face of the stop elements.
the support for guiding the at least one element stack may, in the context of the present invention, be formed for example by a plate or a table.
the at least one endless element or the at least one cam belt also serves as a support, so that it is possible to dispense with separate plates or tables.
the feed device can in principle be configured in a known manner by a slide or the like, but should preferably be adapted to the configuration of the supply device.
the feed device has feed elements which are displaceable and / or rotatable, preferably also perpendicular to the feed direction. This makes it possible that the feed elements of the feed device during the feed process "dive" so that the element stack can be brought by a linear displacement in the desired position, then to raise the feed elements again and bring it into abutment with the stack.
the provisioning device may be an active or passive device.
an active device which actively drives the individual strip-shaped elements and feeds them to a striping machine, according to a preferred embodiment of the present invention, it is at least one transport roller.
a passive provisioning device for example, this can be formed only by a stop, which ensures that the individual strip-shaped elements are kept ready in a ready position, for example, to be picked up by a passing workpiece.
Fig. 1 shows schematically a plan view of a preferred embodiment of the device according to the invention.
Fig. 1 shows schematically a plan view of a preferred embodiment of the device 10 according to the invention for providing strip-shaped elements 1 to a bar molding machine, not shown.
the strip-like elements may for example consist of wood, plastic or similar suitable edge material and have any cross-section and any length.
the device 10 in the present embodiment comprises a delivery device in the Shape of two transport rollers 4, by means of which in each case a strip-shaped element can be conveyed to the strip applicator machine, not shown.
the discharge of the respective strip-shaped elements 1 can be controlled for example by a passage with variable opening.
the device 10 comprises a feed device 5 for advancing an element stack 1 'located between the supply device 4 and the feed device 5 in the direction of the supply device 4, ie in a feed direction.
the embodiment of the feed device 5 will be described later in more detail.
the apparatus 10 is equipped with a feeder 2 for automatically feeding an element stack 1 'between the feeder 4 and the feeder 5.
the feed device 2 is formed in the present embodiment by two cam belts 2, which are each provided with stop cams 2 '.
the cam belts 2 are respectively guided at the ends of the device 10 around pulleys, not shown, so that they can circulate within the device 10. Between the stop cam 2 'of the cam belt 2 each element stack 1' can be formed, which can then be brought by a movement of the cam belt 2 in the desired position between the feed device 5 and the supply device 4.
the mutual distance 3 of the stop element 2 ' is preferably adjustable, for example by the stop elements 2' along the belt 2 are verchiebbar.
the stop elements have on at least one side surface compensation means which allow the insertion of element stacks with different thickness between adjacent stop elements 2 '.
the Compensation means are not shown in Fig. 1, this may for example be leaf springs or other spring means.
the feed device in the present embodiment comprises two feed elements 5 which are retractable, i. in a direction perpendicular to the plane of Fig. 1 are displaceable.
each strip-shaped elements 1 are inserted to form element stack 1'.
a first element stack 1 ' is moved in such a way by means of the cam belt 2, that the foremost strip-shaped element 1 rests against the transport rollers 4.
the feed elements 5 are lowered.
the advancing elements 5 are raised and moved up to the rearmost element of the front element stack 1' in order to press the element stack 1 with a predetermined force against the transport rollers 4.
the foremost strip-shaped element can be discharged to supply it to the not shown Kantenanbringmaschine.
both the feed elements 5 and the remaining workpiece stacks are re-timed. This process is repeated until the foremost element stack 1 'is completely discharged.
the feed elements 5 are lowered and moved into the spaced from the transport rollers 4 starting position, while at the same time by moving the cam belt 2, the next workpiece stack 1 'between the transport rollers 4 and the lowered feed elements 5 is supplied. Now the process described above can be repeated.
