Description

Nov. 13, 1962 e. E. LAMB CONVEX UPPER PLATEN FOR A PULP PRESS Filed Jan. 18, 1960 INVENTOR. GEORGE E. LAMB M 2 HTTOEN 5 This invention relates to presses as used in the paper pulp manufacturing industry. More specifically stated, the invention relates to improvements in presses that are especially designed for the compressing of chemical cellulose pulp bales in order to increase the density of the pulp and to decrease the thickness of space occupied by the bale; the latter being in order that a more favorable ocean freight rate may be obtained where rates are based on the space occupied by the freight rather than on its weight.
Explanatory to the various objects and advantages of this invention, it will here be pointed out that the manner of pressing a paper grade pulp bale is quite important for various reasons well known in the industry. A press, designed to properly press chemical cellulose bales, must be capable of applying a very light cornpressing pressure, or a high pressure s-uflicient to dead press the bale. In a modern, high speed finishing room, the press generally limits the production rate. The cycle of the press and the retention period allowed for escape of air from the pulp bale under compression will determine the number of presses required to obtain a desired production. The retention period must be reduced as much as possible in order to get the shortest pressing cycle. During the last twenty years the retention period has been reduced from approximately 60 to approximately seconds, by reason of utilizing increased press pressures but the using of increased pressures has resulted in production of a greater percentage of stickers and also has necessitated the installation of vacuum breaker plates on the upper press platens in order to prevent, in the opening of the press, the-lifting of the bale from the lower platen and an incident dropping of the lifted bale when the vacuum breaks.
The pressing of bales of dry pulp, especially at high speeds, involves a number of factors not ordinarily found in other pressing operations. For example, a pulp bale exerts a constantly increasing resistance to compression as the pressing progresses and also, by reason of spring back of the bale, exerts high but decreasing pressures on the press over a considerable distance as the press opens. The closing rate of a properly designed pulp press will decrease as the press pressure increases, so as to utilize the full power of the pulp motor over the entire closing cycle and the press must have an adequate means of decompressing the bale.
In view of the foregoing explanatory matter, it has been the principal object of the present invention to provide an improved form of press platen for a pulp press, incorporating therein, certain novel vacuum breaking and design features whereby the present retention period for dissipation of air from the bale being pressed may be further reduced.
It is a further object of the present invention to provide a press platen with a bale engaging surface of novel contour that, in use of the platen, in bale pressing, avoids the trapping of air in the bale under compression and expedites air exhaustion therefrom. Furthermore, it is an object of this invention to so design the bale contacting surface of the platen that the compression of the bale progresses from the inside areas to the outside areas thereby bringing about a faster outflow of air from the bale and avoids compression of pulp fibers about the Patented Nov. 13., 1962 2 outer edge surface of the bale and thus permits easier flow of air within and its outflow from the bale.
Yet another object of the invention resides in the provision of an improved press platen, embodying the objects and advantages above recited, whereby under controlled pressures a perfectly flat top surface may be pro duced on the pressed and finished bale without lengthening the retention period.
In accomplishing the above mentioned and other ob jects of the invention, I have provided the improved details of construction, the preferred forms of which are illustrated in the accompanying drawings, wherein:
FIG. 1 is an elevation of a typical pulp bale press equipped, with a press platen embodying the improvements of the present invention therein.
FIG. 2 is an enlarged sectional View of the platen, taken on line 2-2 in FIG. 1.
FIG. 3 is an enlarged sectional detail taken on line 3-3 in FIG. 2 showing vacuum breaking air channels and air escape ports.
FIG. 4 is a perspective view of the press platen of FIG. 1, removed from the machine and somewhat exaggerated in scale for better understanding.
FIGS. 5 and 6, respectively, are perspective views of press platens of alternative forms.
The present invention anticipates that a platen, embodying the present improvements, is applicable, in its use, to presses of various designs, makes and mechanisms and it is not the intent that it be restricted to the type of press which has herein been shown as being typical of pulp presses in general.
Before describing the present invention, attention will be directed to the fact that, in the usual form of pulp press, both the top and bottom platens have fiat and parallel bale engaging surfaces. A a result, the cellulose fibers in the bale are uniformly compacted since a uniform compacting pressure is applied over the entire top and bottom surface of the bale, and as a result, air in the bale is trapped between the fibers. Since the bale is porous, the air will gradually escape and as it does, the fibers will bend to accommodate themselves to the spaces originally occupied by the compressed air.
It has been observed that with higher pressures and the increased speed of press closing, an increased length of retention period has been required. Actually, a shorter over-all press cycle was obtained by a slower application of pressure that avoided air trapping.
The basis of the present invention resides in so designing the contour of the platen that it first comes in contact with the center of the bale surface as the press closes, subjecting the air contained therein at the center to a greater pressure than at the edges, thereby bringing about a faster outflow of air from the bale, due to the delayed compression of the fibers around the bale edges.
It will also be called to attention that, in the normal pressing by use of fiat surfaced platens, the center of the bale is apt to be left slightly convex, unless an excessive retention period is allowed; this by reason of compression of fibers about the bale edges while air is still trapped or held in the bale center.
The designing of the present platen has been to reduce air trapping to a minimum and effect the progressive application of pressure to the bale from center to to the outer edges thereof to expedite the outflow of air therefrom.
Referring more in detail to the drawings.
The press, herein shown in FIG. 1, is typical of presses to which the present platen may be applied. It comprises a base frame structure designated, generally by reference numeral 10; an opposedly related upper structure 11 that is joined to and supported from the base frame structure by paired laterally spaced columns 1212, disposed in parallel relationship. A cross-head 13 is slidably mounted on the columns 1212 for movement toward and from the base frame. The base frame structure 10 is horizontally disposed and mounts thereon a bale supporting platform 10x upon which a pulp bale, designated at 14, is here shown to be properly disposed for pressing.
The means supplying power for opening and closing the press is not herein shown in detail as it may be any suitable source. It is herein represented as a hydraulic cylinder 15.
Fixed to the under surface of the cross-head 13 is a press platen 16 embodying the improvements of the present invention. This platen, as has been well shown in FIGS. 2 and 4, is of rectangular form, and has horizontal dimensions that are preferably slightly greater than the dimensions of the top surface of the bale 14 to be pressed. The platen is fixed to the underside of the cross-head 13 in such position as to symetrically engage the top surface of the bale incident to the closing of the press against the bale. The top surface of the platen is fiat and is seated flatly against and secured to the under surface of the cross-head 13 and it is formed from edge to edge of this top surface with a plurality of air escape channels 18 from each of which channels, air escape passages or holes 19 lead to the bale engaging surface of the platen as best seen in FIG. 3; these holes being at relatively close intervals over the platen surface.
An important feature of construction of this platen resides in the contour of its bale engaging surface. It is shown in FIGS. 2 and 4 that the bale engaging surface is convex, both in its transverse and its longitudinal direction. However, it might, in some instances be convex in one direction only, as has been shown in the modified or alternative form illustrated in FIG. 5. It is also proposed that such platens might also be made with a flattened pyramidal bale engaging surface such as that of the platen of FIG. 6. In this latter device, the pyramid has been merged into a spherically curved tip, as designated by reference numeral 20.
In the pressing of a pulp bale, in a press using the platen of FIGS. 2 and 4, the problem of exhausting air long distances through the bale through highly compressed fibers is accomplished. The same advantages reside in use of the platens of FIGS. and 6 by reason of the progressive application of pressure from the bale center outwardly.
The vacuum breaking details of the platens are not necessary to the operation of exhausting air from the bale, but are necessary to a satisfactory commercial operation of the press. The combination of the platen surface contour and the vacuum breaking features are quite desirable in order to obtain a shorter retention period; a satisfactory flat surface on the bale, and a satisfactory release of the pressed bale in the opening of the press.
What I claim as new is:
A pulp bale press of the character described comprising a fixed means for support of a stack of pulp sheets or the like, a vertically movable means disposed for movement toward and away from said fixed means, and a platen connected to the lower portion of said movable means, said platen comprising a unitary member having an upper surface and an opposed stack engaging surface, said surfaces being connected by side surfaces, said upper surface being disposed adjacent the lower portion of said movable means, said stack engaging surface being generally convex with the thickest portion of the platen disposed at the central portion of the platen and with the thinnest portion of the platen disposed along peripheral portions of the platen so that the stack engaging surface initially engages the top surface of a stack of pulp sheets at a medial point of the stack and progressively engages such top surface toward the peripheral edges of the top surface, said platen having a plurality of air ports formed therethrough, the lower ends of each of said ports opening through said stack engaging surface, said upper surface having formed therein a plurality of spaced air channels extending substantially all the way across the upper surface of the platen, said air channels opening through at least one of said side surfaces, the upper portions of each of said air ports opening into one of said channels with a plurality of air ports opening into spaced portions of each of said channels thereby providing communication between the lower portion of said air ports at said stack engaging surface and atrnoshpere.
