Definitions
- the present invention concerns a process and an apparatus capable of carrying out stamping of pieces of substances having a pasty consistency and especially stamping of pieces of normal or synthetic soap or soaps made from a mixture of normal and synthetic soaps.
- use is made, for example, of the machines described in Mazzoni patent N° 770.188 of May 23, 1964, in Jones patent (U.S.A.) N° 501.873 of July 9, 1930, in S.A.S. patent N° 769434 (Italy) and N° 1617262 (Germany) and in Binacchi European patent application N° 0095667.
- a first type of soap stamping machine has a part called a disk or star or disk star that has its axis of rotation at right angles to the direction of travel of the soap on the feeding and unloading belts; we will call this family of machines the rotating disk type.
- the operating speed expressed in terms of number of strokes per minute is 100 - 150 for the high-speed or disk machines and 50 - 60 for the low-speed or rotor machines, according to type.
- - feeding the piece to be stamped is taken from a so-called feed belt and transferred to the stamping area;
- stamping the piece is stamped between two mold halves;
- the stamped piece is transferred from the stamping area to a so-called unloading belt;
- the stamping scraps must be removed from the stamping area so as not to interfere with shaping of the next piece.
- the members that cooperate to perform the above described operations vary in number and operating mode in the various known types of machines mentioned above, but they have as their distinguishing feature the drive taken from a single central driving shaft and transmitted simultaneously by means of kinematic chains.
- This shared drive is disadvantageous in that the reciprocal movements are established once and for all during construction of the machine drive, according to the type of kinematic mechanism installed; when changes in these reciprocal movements later become necessary to shape pieces of different dimensions and/or shapes, the kinematic motions must be changed by replacing the mechanical parts of which they are composed.
- Another disadvantage is caused by the elasticity of the kinematic system, especially when the chain of drive members is so long as to lead to distortion of the kinematic system, either due to the stress of the stamping action or because of inertial forces caused by the intermittently moving masses, which cause vibrations and imperfect positioning of the driven members.
- the aim of the present invention is to create a drive for a stamping macnine for soap and similar substances of a flexible type, i.e. capaole of adapting to highly variable types, shapes and sizes of soap.
- a machine has thus been created that allows the respective drives and laws of movement of the members to be modified even after construction of the machine, since only the program that controls the system is affected and not the kinematic mechanisms.
- the proposed machine also makes it possible to take up the elastic yielding caused by stamping stress, since the final position of the upper mold half can be defined at the time of stamping by making a mold half advance further by an amount equal to the yielding; moreover these yieldmgs are less than those occurring with a kinematic chain , since the mechanical elements forming the chain are no longer present, each one of them giving rise to a certain yielding.
- Fig. 1 shows an axonometric view of a first embodiment of the low-speed, rotor type
- FIGS. 2 to 5 show a cross-section illustrating the processing sequence that takes place on the machine in Figure 1;
- Fig. 6 shows an axonometric view of a stamping machine of the highspeed or disk type.
- the members making up the rotor system are a stamping slide 1, a rotor 2, a handling unit 3 for the pieces to be stamped S1 (normally in the form of feeding suckers); a handling unit 4 for the stamped pieces S2 (this too is normally in the form of unloading suckers); a punch plate 5 for the excess soap ES; a feed belt 6 for the pieces to be stamped S1, an unloading belt 8 for the excess soap ES; a translating (or upper) mold half 9; a rotating (or lower) mold half 10.
- Fig. 1 is a schematic view of the system with reference to an unrestrictive exemplary embodiment, suitable for processing two cakes of soap simultaneously; as it can be readily understood, this example can easily be developed in further multiples to process four, six, eight cakes of soap simultaneously and so forth. Operation of the machine will now be described with reference to figures 2, 3, 4 and 5; the pieces of soap to be stamped S1 arrive, already cut, on feed belt 6 ( Figure 3).
- the feeding and unloading suckers hold the soap before and after stamping by means of vacuum. During release of the pieces the vacuum is cut off and compressed air is blown in to aid release. Both the vacuum and the air are controlled by means of solenoid valves that are not illustrated.
- the adjustments described above are carried out by actuators using hydraulic servocylinders, hydraulic motors or electric motors for example, by programming their individual movements in a suitable manner in the coordinating and controlling units; in reality it is more practical to perform some adjustments mechanically and manually using tools, according to the conventional system, leaving automatic adjustment for those movements where it proves really advantageous.
- the embodiment in Figure 6 envisages pairs of opposing stamping slides 12 each bearing mold halves 13, a rotating disk that serves to transport the pieces of soap to be stamped A1, the pre-stamped pieces A2 and the finished pieces A3, as well as the scraps A4. Also envisaged are introducing members 15 for the pieces to be stamped A1, suckers 16 to pick up the stamped cakes, a feed belt 17 for the pieces A1, an unloading belt 18 for the finished soap A3, an unloading belt 19 for the excess soap A4.
