Description
- Known from EP-A-0 292 067 is a separating device which is equipped for separating pianos provided with at least one weakening line into elements or groups of elements.
- The invention has for its object to provide an arrangement making it possible, with use of two or more such known separating devices, to ensure a great flexibility, handling speed and continuity.
- In order to realize this objective the invention provides an arrangement of at least two separating devices for separating into elements or groups of elements pianos having at least two weakening lines which are oriented at an angle to one another and partly bound the elements, which devices each comprise:
a first clamping member for fixedly clamping on one side of a first weakening line a piano or stack of pianos, in this latter case such that the relevant corresponding weakening lines of the stack lie in a plane extending perpendicularly of the main plane of a piano;
a second clamping member for fixedly clamping the plano on the other side of this weakening line; and
tilting means for mutual tilting of the first clamping member and the second clamping member such that the plano or stack of pianos is separated into two elements or groups of elements by breaking the said weakening line;
which arrangement further comprises transporting means defining a transport path which, - feeds the planos into a first separating device and discharges said planos therefrom in a direction perpendicular to the said first weakening line,
- alters the transporting direction such that this extends in a direction perpendicular to the second weakening line, and
- feeds the pianos into the second separating device in this direction.
- The invention relates more particularly, but not exclusively, to such an arrangement with at least three separating devices and transporting means embodied such that at least two transport paths are defined thereby which each comprise at least one separating device, which at least two transport paths have a common portion comprising at least one separating device, wherein at the location of the transition from the common portion to the individual portions means are present for transporting the planos alternately over the respective transport paths.
- Due to the fork-shaped structure, such an arrangement makes it possible to split one transport path into two or more transport paths or to merge two or more transport paths into one transport path.
- In the common portion the separating device can for instance have a greater width or be equipped for a greater handling speed; the separating devices in the individual portions can be relatively small or have a slower handling speed.
- The invention thus offers the possibility of allowing two punching machines for the pianos to be followed by one further handling line.
- The function of the separating devices and the transport means can be controlled from a central control unit, if desired making use of means for detecting for example the length and width of the planos or stacks of planos for handling. Fully automatic operation can thus be put into effect. This means that it is possible to transport different sizes of planos or stacks of planos through one and the same separating device in one handling operation. The central control unit determines the setting of the separating devices on the basis of the signals generated by the detecting means.
- Inserting pianos or stacks of planos from two punching machines into the arrangement can result in a significant cost reduction compared to a known arrangement in accordance with EP-A-0 292 067.
- The invention will now be elucidated with reference to the annexed drawing, in which:
- figure 1 shows a schematic perspective view of a first arrangement according to the invention;
- figure 2 shows a separating device wherein the dividing plane extends in the transporting direction;
- figure 3 shows a perspective view of another separating device;
- figures 4, 5 and 6 show schematic side views of the device according to figure 3 in successive phases of a separating cycle; and
- figures 7, 8, 9 and 10 show four different arrangements according to the invention.
- The device depicted in figure 1 comprises a
feed conveyor 1, aseparating device 2 and a discharge conveyor 3. The separatingdevice 2 is formed by a first clamping member 4 and asecond clamping member 5. - The first clamping member 4 comprises a
short conveyor 6 which is trained about twobelt rollers 7. Arranged under the upper half ofconveyor 6 is a support, not shown in the drawing, for absorbing the clamping forces. Arranged above the conveyor is a pressure plate 8 which is fixed by means of a bracket 9 and ashaft 10 to arod 11. Therod 11 is movable in vertical direction by means of ahydraulic cylinder 12. - The
second clamping member 5 is likewise formed by aconveyor 13 which is wound around afirst belt roller 14 and asecond belt roller 15. The shaft of thebelt roller 14 is arranged fixedly so that thebelt roller 14 can only rotate while the shaft ofbelt roller 15, like theconveyor 13, can move arcuately downward to a lower position as indicated by dashed lines. It is also possible to cause the assembly formed by therollers roller 14. - Also arranged under the upper half of
conveyor 13 is a plate, not shown in the drawing, which can likewise take part in the downward oriented tilting movement of thebelt 13 and themovable belt roller 15. - Arranged once again above the
belt 13 is a pressure plate 8 which is fixed by means of a bracket 9 and ashaft 10 to arod 11 so that the pressure plate can tilt relative to therod 11, while theshaft 10 is likewise movable in vertical direction by means of ahydraulic cylinder 12. It is also possible to design the whole press-ondevice rollers - Arranged above the
belt 13 are twomovable stops 29 which can be moved upward by means ofhydraulic cylinders 30. - Adjacent to the conveyor 3 is arranged a
second separating device 16, the construction of which corresponds with the above described separatingdevice 2. However, the dividing plane of this second separatingdevice 16 extends perpendicular to the direction of the dividing plane of the first separating device. By connecting these twoseparating devices - A pusher member 17 is arranged to transport the elements for separating from the conveyor 3 to the
second separating device 16. This pusher member 17 is connected to ahydraulic cylinder 19 by means of arod 18 so that the pusher member can move in the direction extending perpendicularly of the direction of movement of conveyor 3. Instead of a conveyor a system of belts or chains can also be used. - Arranged following the
second separating device 16 is asecond discharge conveyor 20, above which apusher member 21 is once again arranged which is connected to ahydraulic cylinder 23 by means of arod 22 so that thepusher member 21 is movable in the direction extending perpendicularly of the conveying direction of thebelt 20. Arranged adjacent to thisbelt 20 is adischarge conveyor 24. - The operation of the combined separating device will now be discussed. Supplied on the
conveyor 1 are sheets of cardboard which are each formed by fourplanos 26. Theplanos 26 are mutually separated by twodividing lines separating device 2. Theconveyors movable stops 29. - The pressure plates 9 are then moved downward by means of the
hydraulic cylinders 12 until they clamp the relevant planos fixedly against therespective conveyors belts - The
stops 29 are then moved away by means ofhydraulic cylinders 30 and the second clamping member performs a tilting movement about the tilt axis. During this tilting movement theconveyor 6, the support, theconveyor 13 and theroller 15 rotate around the axis of theroller 14 or downward around the tilt axis arranged elsewhere. Since the pressure plate 8 is in any case rotatable about theshaft 10 and since the pressure from above remains applied, it will take part in this turning movement so that the planos clamped in between the second pressure plate 8 and theconveyor 13 will also take part in this movement and the two stacks of planos are separated along the break line. When this tilting movement is completed it is carried out again in reverse direction. - The
conveyors - These
stacks 31 of planos attached in pairs are there transported one by one by thepusher member 19 to thesecond separating device 6 and again subjected to a separating operation. Resulting from the processing in this second separating device are separate stacks ofplanos 32 which pass onto theconveyor 20 and are there pushed by thepusher member 21 one by one to thedischarge conveyor 24. The cardboard sheets are thus separated into thick stacks in two directions without human intervention. - In the embodiment shown in figure 2 the
separating device 33 consists of twoconveyors conveyor 34 is trained about twobelt rollers conveyor 35 is trained about twobelt rollers belt rollers belt rollers belts support conveyor pressure plate 42 which is connected to a hydraulic cylinder 46 by means of brackets 43, ashaft 44 and a rod 45. - The operation of this second embodiment of the present invention is the same as that of the embodiment shown in figure 1, except that the conveyors are tiltable in their lengthwise direction. This has the advantage that this device can be placed immediately behind the first separating device of figure 1 so that no change of transporting direction is necessary for separation in the second device. Both separating
devices - Using this device it is also possible to mutually separate the stacks of pianos without human intervention.
- The above described embodiments relate to the separation of stacks of planos. The device according to the present invention can likewise be used for separating other separable objects.
- Use is made in the above described embodiments of
hydraulic cylinders 12 for causing the movement of the pressure plates. It is also possible to make use of pneumatic cylinders, electro-motors or hand wheels. - Other transporting means may also be employed instead of the pusher member used in the above embodiments.
- Using the device according to the present invention it is also possible to separate elements which are each partly separable in a plurality of parallel planes, for instance when two elements are mutually connected by a crenellated dividing line and the connections for separating are only present on the end faces.
- Such elements can also be separated stepwise, that is, successively plane by plane.
- When the device intended for two mutually perpendicular separating planes is used for only one separating plane, one separating device can be switched off and used as transporting device.
- The principle according to the invention can also be implemented by only one separating device in combination with buffer and transporting means, which carry a stack of objects already processed once through the separating device for a second time such that separation along the other transversely positioned weakening line(s) takes place.
- Figure 3 shows a
separating device 101 in perspective view. Anticipating the discussion of figure 4, figure 5 and figure 6 it is pointed out here that the feed into thedevice 101 of stacks ofplanos 102 takes place by making use of transportingbelts 103. During the separating operation the stacks ofplanos 102 are supported by up and downward movable support beams 104 extending therebetween. - Figure 4 shows the
device 101 in side view with thecover 105 removed. - The stack of
planos 102 is fed into thedevice 101 by the transportingbelts 103 and a set of transportingbelts 106 connecting thereto which co-act with a second set of support beams 107. - The device comprises an in-
feed frame 108 and adischarge frame 109. The in-feed frame 108 is fixedly arranged in the transporting direction and comprises the transportingbelts 103 and the support beams 104 which are up and downward movable by means ofhydraulic cylinders 110 for pressing an insertedstack 102 against asupport 111 situated above. In corresponding manner thedischarge frame 109 compriseshydraulic cylinders 112, using which the support beams 107 are movable upward for pressing thestack 102 against asupport 113. Thedischarge frame 109 is pivotable about a pivot shaft 114 relative to the in-feed frame 108 such that thedischarge frame 109 is tiltable under the influence of ahydraulic cylinder 115. This tilting is controlled from control means (not drawn), as is the operation of the other active components of thedevice 101. - It is noted that drive means for the transporting
belts - In the device shown in figure 4 the
stack 102 is fed into thedevice 101 according toarrow 116 such that the weakening lines present in the stack ofplanos 102 all lie in one vertical plane corresponding with the position of the pivot shaft 114. - Figure 5 shows the subsequent situation in which the support beams 104, 107 are carried upward by actuation of the
hydraulic cylinders planos 102 against thesupports - Figure 6 shows the following phase wherein in this clamped situation the
discharge frame 109 is tilted relative to the in-feed frame 108 by actuating thehydraulic cylinder 115. As a result of the thus exerted force the stack is divided into two parts along the central plane with the weakening lines of the planos. - After reaching this situation the device is returned to the situation as in figure 5, wherein however the two
stacks belts stacks device 101 either pressed against one another or with intermediate spacing. - Figure 7 shows the feed into a
device 101 of stacks ofplanos 119 with onetransverse weakening line 120 and two longitudinal weakening lines 121. Thedevice 101 separates thestacks 119 into part stacks 122, each with two longitudinal weakening lines. By means of rotation means (not drawn) thestacks 122 are turned through 90° relative to the conveyingdirection 116, as designated witharrows 123, and carried with this new orientation into a followingdevice 124 which can be functionally identical to thedevice 101 but can take a narrower form. Thisdevice 124 divides the part stacks 122 into separate stacks ofelements 129. - Figure 8 shows a configuration in which, by means of pusher members (not drawn) functionally identical to the
pusher members direction 125, and to the right, thedirection 126, for feed into separatingdevices device 124 where they are processed in the manner as indicated in figure 7 with reference to thedevice 124. By means of rotation means (not shown) each stack ofelements 129 is carried away in sideways direction according toarrows device - Figure 9 shows another arrangement according to the invention which will be dealt with more briefly after the foregoing comprehensive discussion of figure 8. The arrangement shown in figure 9 has two confluent transport paths designated 132 and 133. Other than in the embodiment according to figure 8 it is the case that not one transport path is divided into two transport paths but that two transport paths are merged into one transport path. After the description above, figure 9 requires no further elucidation.
- The arrangement of figure 10 differs from the arrangement of figure 9 insofar as a
transport path 134, in contrast to thetransport path 133 according to figure 9, has two separatingdevices transverse weakening lines 137 are first divided into two and, after being transported in transverse direction, are subsequently fed into thedevice 128 such that they are separated once again along the other weakening lines. - Attention is drawn to the fact that use can be made of only one separating device in combination with transporting means for twice feeding pianos therethrough, for dividing the planos into part planos respectively along the weakening lines in the one and the other direction.
Claims (3)
- An arrangement of at least two separating devices for separating into elements or groups of elements planos having at least two weakening lines which are oriented at an angle to one another and partly bound the elements, which devices each comprise:
a first clamping member for fixedly clamping on a side of a first weakening line a plano or stack of planos, in this latter case such that the relevant corresponding weakening lines of the stack lie in a plane extending perpendicularly of the main plane of a plano;
a second clamping member for fixedly clamping the plano on the other side of this weakening line; and
tilting means for mutual tilting of the first clamping member and the second clamping member such that the plano or stack of planos are separated into two elements or groups of elements by breaking the said weakening line;
which arrangement further comprises transporting means defining a transport path which,- feeds the planos into a first separating device and discharges said pianos therefrom in a direction perpendicular to the said first weakening line,- alters the transporting direction such that this extends in a direction perpendicular to the second weakening line, and- feeds the planos into the second separating device in this direction. - An arrangement as claimed in claim 1, with at least three separating devices and transporting means embodied such that at least two transport paths are defined thereby which each comprise at least one separating device, which at least two transport paths have a common portion comprising at least one separating device, wherein at the location of the transition from the common portion to the individual portions means are present for transporting the pianos alternately over the respective transport paths.
- An arrangement as claimed in claim 1, comprising one separating device and transporting means for twice feeding planos therethrough, for dividing the planos into part planos along the respective weakening lines in the one direction and the other direction. It will be apparent that with such an arrangement economic advantage can be achieved in particular conditions.
