Description
- The invention refers to a pressing plant for the formation of bales of pressed textile materials comprising: at least a first pre-pressing, group associated with means for the loading of the material; at least a second final-pressing group associated with binding means and, possibly, with wrapping means to make a film envelope or the like; and carriage means for transferring the partially pressed material from the first pre-pressing group to the second final-pressing group which are, substantially, at the same level.
- A pressing plant of this type is disclosed in DE-A-2 911 958. In this known plant there is provided a set of means for transferring the pre-pressed material from the pre-pressing groups to the final pressing group, each means comprising two parts, namely a carriage and a nearly cylindrical container for the material to be pressed. These two portions are put together in order to carry out the filling and pre-pressing operations. Transferring means running along trucks move the filled up container from the relevant pre-pressing group to the final pressing group. Before reaching the final pressing group, the container is removed from the relevant carriage and placed on the said final pressing group. The pressing and wrapping operations must be completely carried out before removing the container from the said final pressing group. Consequently, a plurality of carriages and containers is needed to carry out the pre- and final pressing operations and to transfer the pre-pressed material to the final pressing groups. Further a complex transfer system must be provided to move said carriages and said containers and to separate them one from the other before final pressing is effected.
- It is an object of the invention to realize a pressing plant of the above mentioned type, which is particularly simple, compact and which has a high productivity.
- Substantially, a pressing plant according to the invention is characterized in that: said carriage transfer means include fixed side walls and a movable wall, apt to define a filling and pressing space, horizontal upper mobile combs, and a lower shiftable diaphragm; and that means are provided able to control said diaphragm so that it retains the pressed material in the carriage during pre-pressing and transfer and so that it can be excluded during the final pressing, and means are provided able to control said mobile wall in order to open it after the final pressing and permit the removal of the carriage.
- In a particularly advantageous embodiment, the pressing plant according to the invention may comprise two pre-pressing groups spaced out relative to the second final pressing group and disposed on opposite sides thereof, and two respective carriages with mobile wall, the two mobile walls of said carriage being opposite one to the other.
- The lower diaphragm of the carriage may be formed so as to be able to slide on its own plane, while the combs rotate about a pivot to reach the opening and closing positions on the first pre-pressing group; the lower diaphragm being closed meanwhile the combs are opened for the loading and pre-pressing operations, and both said diaphragm and said combs being defiled after the transfer into the position on the final-pressing group, to allow said final pressing.
- The horizontal lower diaphragm may comprise a continuous lamina or a grid with bars being parallel to the slide direction and compatible with slots provided in the base of the final pressing group for the binding.
- The invention will be better understood by the following description and the accompanying drawing which shows a practical non limitative exemplification of the same invention. In the drawing:
- Fig. 1 shows an ensemble front view of a plant according to the invention with two pre-pressing groups and one final pressing group in intermediate position;
- Fig. 2 shows a schematic view from line II-II of Fig. 1; and
- Fig. 3 shows a very rough, local section according to the line III-III of Fig. 2.
- According to Figs. 1 to 3,
number 501 indicates a central housing for a final-pressing group, and abase 503 and amobile wall 505 of this group are visible, saidwall 503 being apt to be drawn near thebase 503 by means of a hydraulic or equivalent power-system 507. Thebase 503 and themobile wall 505 are realized with channels to permit the binding of the bale of pressed material after completion of the pressing and of a possible wrapping by envelope-forming films. The binding is effected by abinding unit 509 of a type per se known, in one or more stages. At the two sides of thehousing 501 two pre-pressing groups, generally indicated by 511 and 513 are disposed, each of which includes a feeding system with a mechanical orpneumatic conveyor 515, astorage tank 517 and apusher 519 able to push the material from thetank 517 to adrop room 521 overhanging a filling and pre-pressing space. The filling and the pre-pressing are carried out with the aid of apresser 523 alternatively movable through the control of cylinder-piston systems 525 in order to preliminarily tamp and press - by a plurality of lowering and lifting cycles - the material in said filling and pressing space. - The filling and pressing space for each of the two
groups carriage drop room 521 up to a position below themobile wall 505, each carriage being able to slide just above thebase 503 by resting and sliding on guides disposed at the sides thereof. Each carriage, like the one indicated by 529 to be described below, has one horizontallower diaphragm 531, which can be made to slide by means of suitable fluid-operated control means 533 or the like for a movement along its own plane. The carriage also includes three vertical fixed walls of which one indicated by 535 is transversal and the other two indicated by 537, 539 are longitudinal relative to the direction of the carriage movement which is indicated by the double arrow f in the drawing. On the top of the threevertical walls pre-pressing tank 521, a second horizontalupper diaphragm 541 is provided which may consist of a single structure or of two parts separately movable. Also said diaphragm 541 - which may be formed by two movable parts - may be moved along its own plane through suitable fluid-operated or equivalent control means 543. In thewalls 539 two sets of slots are formed for the introduction therein ofcombs 600, which have the function of retaining the material during the spring back phase when thebox piston systems 602. Theupper combs 600 and the threewalls mobile wall 545 vertically hinged at 547 to the wall 537 (see Fig. 1) in order to be opened and respectively closed (as far as it comes in contact with the wall 539) so as to define said filling and pressing space. In each carriage, themobile wall 545 is the inner one facing the second group, centrally located, for the final pressing. Also the opening and closing of themobile wall 545 is controlled by a fluid-operated or equivalent control means 549. - The plant operates as follows. Each carriage is brought under the
drop room 521 of its own pre-pressing group in such a condition as to define the filling and pressing space, with thediaphragm 531 and thewalls mobile wall 545 in the closing arrangement. In these conditions, the filling of this space takes place in the usual way, with subsequent cycles of drop discharge and of preliminary pressing by thepresser 523. Retaining means may be predisposed for retaining the partially pressed material between one lowering cycle and another of thepresser 523, in order to avoid the progressive swelling of the material. At the end of the pre-pressing operation, in the space defined on the carriage, as described above, the combs 600 - which retain the material - are put into an active position, theupper diaphragm 541 is closed and the carriage is transferred to the second group of final pressing until thelower diaphragm 531 is brought just below thebase 503 and the upper combs are brought just below themobile wall 505; in the meantime the drop of the material into theroom 521 of the pre-pressing group is not interrupted. The pressing group starts its action while the twodiaphragms walls base 503 and themobile wall 505. A film intended to form envelope is possibly already available on thebase 503 and under thewall 505, so as to form an envelope or wrapping after the pressing. The intervention of the binding unit completes the packaging. In order to operate - after the final pressing - the possible formation of the envelope and, anyway, the binding, thewall 545 is opened and the carriage is moved away in the direction opposite to the one according which it has transferred the material under the group of final pressing; for this moving away of the carriage thewalls - The operations performed by the two
carriages - The
combs 600 and the pressing means may be realized in such a way as to avoid mutual interferences. - In this way, there is obtained a plant of limited extension and capable of being installed without any costly partial laying underground of the structures. The construction of the group results much simpler and thus far more economical and of much more limited overall dimensions which increases its economy also as far as the required space is concerned. These and other objects and advantages will result apparent to those skilled in the art from a reading of the preceding description.
