HANDLING DEVICE

FOR MANUFACTURING MOLDS

  OR FORMWORK OF CONCRETE OR CONCRETE PANELS

  The present invention relates to rule handling devices for manufacturing molds or panel formwork

concrete or composite.

  A rule or spinning or played, a lateral or longitudinal panel formwork allowing the molding in planimetry and thickness, and can also allow profiling forms

  various with or without steel.

  The use of manufacturing molds or pan formwork

  Concrete or composite materials are related to the building industry which has long been sought for industrialization, that is, for which the optimum conditions for the execution of construction work suited to modern economic technical progress through careful and methodical preparation of the work This implies the use at all stages of implementation of advanced mechanical equipment and machinery for the preparation, manufacture, handling and implementation of materials, but also imposes the scientific organization of the building site and more generally and in such a compelling way, the organization

  rationality of all the functions which

run to the art of building.

  A particular aspect of industrialization is the prefabricated

  which tends towards the incorporation, in a single element, of the works which in this one are necessary for the execution of a construction. In the context of the present invention is more particularly interested in relatively large concrete or composite panels that are manufactured in formwork or

  molds o some operations are still done manually.

  Because the panels are made on horizontal tables

  fixed tables or horizontal tables that can be raised and 251 Ot 27 take the demolding of the panel, a vertical position, the slices of the panels are defined by rules, a low articulated or pivoting or movable rule, one or two high rules, at least two or more, four fluent, lateral rules In this case we speak of two lateral rules and two central rules The manipulation of these rules is still done now in workshops men arm either manually or using sometimes external, but auxiliary means of lifting The mechanical manipulation or assisted by mechanical means enslaved by electric, hydraulic, pneumatic or combined organs, and more programmed, does not exist yet for the rules

formwork.

  FIG. 1 shows how the rules are arranged on a manufacturing table of a concrete or composite panel according to the art

prior.

  The outer rectangle R marks the limits of the table In 1 is the low ruler, here in one part although it is possible to manufacture it in several parts In 2 is a high ruler, in 3 an outer ruler and in 4 a side rule

Central.

  In this figure, two forms have been presented.

  According to the prior art, the manipulation of these rules is done manually and in what follows we will give an example of all the manual manipulations that there would be to do, in a case of

manufacturing all in all current.

  When, for example, one manufactures on a table panels varying in size, the low ruler remains in place on its hinge pins On the other hand, the high ruler or rules depending on the case, are manually removed to release the panel sound mold and unmold and remove it from its work area In addition, often, the panels vary in dimensions because dissimilar rules do not rise to the same place compared, for example, to the previous casting This prohibits to leave the higher rules and

side to the same place.

  It is conceivable in these conditions that an aid or a mechanical assistance for the manipulation of the rules is interesting, otherwise

  important and in most cases highly desirable.

  The object of the present invention is therefore a device for manipulating

  rules for manufacturing molds or forms of concrete or composite panels that replace the manual

  the manipulation of the rules and facilitates it.

  According to the invention, a rule-handling device comprises at least one bar or manipulator comprising means for fixing said manipulator to the corresponding rule, motor means acting on the manipulator and rendering it

  movable either linearly or angularly, or both,

  the corresponding movement of the rule and allowing on the one hand the release of the panel, regardless of the position of the table carrying the mold or the formwork, and on the other hand the setting in place

rules on the table.

  Other features or advantages of the invention appear

  in the following description of examples of implementation of the

  manipulation device given by means of the figures which represent

  feel: Figure 1, the layout of the rules on a panel manufacturing table; Figure 2, an embodiment of a handling device according to the invention; Figure 3, a layout diagram of handling devices around a manufacturing table;

  FIG. 4, another embodiment of a handling device

  lation. As has been said in the introduction to this

  description, the object of the invention is to define what has been called a

  manipulator capable of moving, or removing and relocating

  the rules defining the formwork in which

  Concrete or composite skins are prefabricated.

  The latters are capable of acting on the rules, be they low, high, lateral lateral or central lateral, when several forms, two in general, are arranged on the same table, as shown in Figure 1 representative of the art previous It should be noted that the manipulators perform a job that until now was done manually, workers moving the rulers by hand, or having hand-on them gripping means

  connected to traction or lifting devices.

  The manipulators according to the invention can also be grouped on mobile supports that can move from one manufacturing table to another, the operations they perform being programmed so that the work they perform is done without solution. In addition, the arrangement of the manipulators on the supports is thus made that the manipulators are able to act

  on the corresponding rules without setting up and preliminary settings.

long-term

  Figure 2 shows a handling device in a

preferential embodiment.

  According to the invention, however, it is possible to consider in this figure, the device designed in its general form, that is to say the right or left part indifferently limited by the dashed line P. The device thus comprises a bar 8 or manipulator carrying at one of its ends fastening means 9 to the corresponding rule These fastening means are thus made that they grip corresponding means fixed on the rule In 13 there is provided locking means, key, cylinder or the equivalent Ce

  manipulator according to the invention must be able to execute certain

  linear or angular or both successively To do this, a motor It preferably pneumatic, but can be electric, hydraulic or other, through a pinion

  leader 61 prints a linear motion to the manipulator.

  In a variant, the bar 8 is a slide and the means of

  fixation -9 are mounted on a carriage 7 movable along the slide.

  A cylinder 10, it ensures the tilting of the bar 8 on which it acts. It appears obvious that the assembly which has just been described, causes in its movements the rule, not visible on the drawing, to

which it is fixed.

  Figure 2 complete, represents a handling device more specifically adapted to the manipulation of rules, high, lateral outer of greater length as is the case in general. It comprises two devices similar to that just described coupled by a rigid transmission shaft 6 in the example described On this shaft driven by a motor Il the motor 110 obviously does not need to be maintained are arranged two

  leading gears 61 and 62 respectively acting on the manipulators

  8-80 latters, or in the case where they are slides, on the carriages 7-70 carrying the respective fastening means 9-90 to complementary means 5-50 (Figure 3) provided on the rules The shaft 6 is

  rigid to ensure a certain synchronization in the

  which are printed to the rulers and avoid any detrimental stress If the motor 110 (110) imparts a linear movement to the manipulators 8-80, a cylinder 10 (100) provides the movement

  desired angle, controlling the tilting of manipulators 8-

  80. In another embodiment, the rigid shaft 6 can be replaced by an electric synchronization system, comprising two motors each driving a driving pinion, and synchronized

between them by any known means.

  For example, to remove a lateral rule, one can print an angular movement at one or the other end, or both, in order to detach it from the corresponding bank.

  cation of panels, bearing as shown in Figure 1, two molds.

  FIG. 3 also includes FIG. 1, with the difference that the rules drawn bear the eyelets 5-50 cooperating with the

  means for fixing the manipulators.

  As can be seen in Figure 3, the handling devices I, 11, III, IV are arranged on a support, which can be movable, not shown, however, and placed opposite the rules on which they will act. device I on the right side 3 outer ruler, device II on the right ruler 2, device III on the ruler 2 on the left and the device

  IV on the outer side ruler.

  It will be noted that there is no manipulation device placed opposite the low ruler This is explained by the fact that generally, for the manufacture of panels on a table, the dimensions of which can vary, the low ruler remains in place on articulation pivots It is however understood that the low ruler can be manipulated like the other rulers The rules high and lateral external must be able to be separated so as to release the panel and to allow the demolding and the out of its

  working area and the manipulators associated with them,

  kill the movement necessary for these operations.

  as, as has been said, often different

  rents, the high and lateral rules can be put back in different places when switching from one type of panel to another, these operations being carried out by the manipulators performing

  movements opposed to those that are performed during demolding.

  It will be noted in FIG. 3, at 60, the presence of a coupling device linking the shafts 6 of the handling devices II and III when the high ruler is of great length. In this case, moreover, the fixing means 9 are in the form of an articulated clevis which is automatically tilted in the vertical direction by action of a stop 12 of the rear end position placed on the

  manipulator This stop is shown only on a single manipu-

  Figure 3 This tilting makes it possible to present the formwork faces of the rulers in a substantially horizontal position but in any case accessible to the greasing cleaning operation which generally takes place after demolding. The locking of the gripping tongs 9 on the rulers by the eyelets 5-50 provided for this purpose is performed by jacks or

  similar systems 13 as shown schematically in FIG.

  Note in Figure 3 the presence of two locations 14-15 arranged on the table R On these locations are fixed, when necessary, manipulators specially adapted to the manipulation of the central lateral rules A realization of

  Manipulators of this type are shown in Figure 4.

  By their implementation, the handling devices, one of which is described in support of FIG. 2, are well adapted to the manipulation of the high rules, whether they are two in number, as shown in FIG. a single copy of

great length.

  The rules are thus movable, linearly, that is to say by translation, the carriages carrying the clamps being driven on the slides by means of the driving gears 61-62 mounted on the rigid shaft 6 controlled by the motor 11 , also angularly displaceable, at least one of the slides can be tilted by action of a jack 10 which obviously can also

switch the other slide.

  These movements can also be performed at rest,

  that is, without any action on rules.

  at 90 slides, the escamote and frees the field of

  There may be a frontal retraction of the slides

  In this case the cylinders are moved to the rear of the

  device and operate in lock.

  Mechanical or other memories can be provided which make it possible to automatically adjust the movements of the fastening means. Moreover, the memories themselves are adjustable,

  following the changes of position of the rules that one desires.

  Handling devices operate in a semi-

  For the outer lateral rules, however, it should be noted that, preferably, as has already been said, the drawing and the repositioning of the rules

2510027 '

  Lateral movements are made rather along an angular path. However other movements that the manipulation device can perform,

  or to which it may be subject, may be considered.

  Thus a manipulator can retract by rotation in one direction or the other It can also move laterally or horizontally in the direction of the ascent or descent relative to its support to facilitate the movement of a table or

  as a rule facilitate the work on the tables.

  For central lateral rules, it is used according to the invention

  According to their position on the table of manufacture of the panels, as it appears in FIG. 1 or FIG.

  Rules can not be easily moved using a

as shown in Figure 2.

  In fact, the central rules can only be dealt with when the high rule (s) have been removed or retracted. This explains why the manipulation devices for central rules are arranged in particular locations such as 14-15.

  on the table R manufacturing panels.

  A manipulation device for a central rule is represented

  According to the invention, such a device comprises a bar or manipulator 16 fixed on the one hand by one of its ends to the central rule 4 by fixing means 17, a mortise in the example described, and on the other hand by its other end to a pneumatic box 24 comprising two jacks 18 and these two jacks are attached to the manipulator 16 by a mortise

  These two cylinders can print to the manipulator two movements.

  occurring respectively in two perpendicular planes

  These two planes are a plane perpendicular to the plane of the figure, and the plane of the figure The movements are printed according to the way we want to act on the

  central rule at the time of demolding.

  In general, the central rules can be fixed to the low ruler l by means of a clevis 21 which is fixed on this low ruler which itself remains fixed but nevertheless capable of pivoting

around an axis.

  The central rule can thus turn around the axis of the screed, of only a few grades, but sufficient to release the edge of the panel 22 that it delimits. This movement, which takes place in the plane of the figure or the panel, is printed. by the so-called pull cylinder 20 In order to be able to emulate the panel in good conditions, the rule 4 and its associated manipulator 16 are "lifted" by means of the so-called lift jack and this movement is executed in a plane perpendicular to the previous; in this case the low ruler 1 rotates about its axis, driven by the central rule to which it is fixed Thus in the case of a central rule, two angular movements in planes perpendicular to each other are to be considered . When the panel has been removed, and after cleaning and greasing, the ruler can be repositioned by the reverse movements. For reasons of ease of implementation, the manipulator 16 is originally slidably mounted in the rule 4 and at the time of the demolding operation the sliding bar 16 is fixed in the mortise 19 can be provided a movable key 23 preventing the

  sliding bar to come down into the ruler intem-

  -timed. In the case of a movable table, placed in a vertical position for demolding and removal of the panel, the angular "lifting" movement performed by the ruler can be caused by placing the table vertically, the panel driving through friction and gravitational force the articulated low ruler 1 which drives the central lateral rule by means of the fitting of the yoke 21 on the axis of the low ruler In this case the lifting jack 18

  maintains the vertical ruler through mortise 19.

  This during the stripping operation is crazy, allowing itself to be dragged into any desired position, facilitating the stripping of the

mold bottom.

  When the panel has been removed and for example the table goes down, the mortise is no longer crazy; its automatic locking keeps the ruler away from the worktop, which, as we have already said, allows for easier cleaning of the equipment and correct greasing. The low ruler attached to the central rule also remains

away from the table.

  This work being accomplished, the mortise 19 is released, the sliding bar 16 after the key 23 has been removed, enters the

  Rule 4 and the latter is put back in place.

  A rule manipulation device has thus been described for

  manufacturing molds or forms of concrete or composite panels.
