Abstract
A discharge of paper or other leaves from the top (S) of a stack is by a rotating feed-roller (17;41) mounted on a carrier (7,11;35-39) that moves progressively along the stack in maintaining the roller (17;41) engaged with the top leaf. The carrier (7,11;35-39), which has a slot-mouth (8;52) through which the leaves are discharged successively by the roller (17;41), is guided in its downward movement by side-wall slots (12;40) of a casing (2;32) holding the stack, and has counter-balancing weights (23;50) attached for adjustment of the pressure of the roller (17;41) on the stack. In one form, the carrier is mounted on a plate which carries a motor for belt-drive to the roller, and which has sliding pivotal movement in the casing to enable the carrier to follow the guide-slots. Alternatively, the motor is located within the roller and ears of brackets on the carrier are located in the guide-slots to hold the carrier from tipping.
Description
- This application is a national stage completion of PCT/GB2007/000384 filed Feb. 5, 2007 which claims priority from British Application Serial No. 0602207.3 filed Feb. 4, 2006.
- This invention relates to methods and machines for discharge of paper or other leaves from a stack.
- The discharge of confetti for spread distribution is used for artistic and other effects in theatre productions and in other entertainment and festive events and for celebration purposes. The confetti is commonly in the form of circular discs of paper, but may be of rectangular-strip or other configuration, and may be leaves of metal- or plastics-foil. A method and machine for such discharge is described in GB-A-2417431, and although such methods and machines have been found especially advantageous for spread-distribution discharge of confetti or other small leaves, they have not been found entirely suitable for corresponding discharge of larger items in the form, for example, of tickets, vouchers and leaflets (having a size approaching, say, 130 mm×70 mm, and larger).
- It is an object of the present invention to provide an improved method and machine in the latter regard.
- According to one aspect of the present invention there is provided a method for discharge of paper or other leaves in spread distribution from a stack, wherein a carrier which carries a rotating member is moved progressively downwardly of the stack in maintaining the rotating member engaged with the top leaf of the stack as the leaves of the stack are discharged leaf by leaf through a mouth defined in the carrier.
- According to another aspect of the present invention a machine for discharge of paper or other leaves in spread distribution from a stack through a mouth of the machine, comprises means for holding the stack, a carrier which is mounted for movement downwardly of the stack and which includes means for defining the mouth of the machine, a rotatable member carried by the carrier for engaging the top leaf of the stack, and means for rotating the rotatable member to discharge the leaves of the stack leaf by leaf through the mouth from the top of the stack.
- The rotatable member of the method and machine of the invention may have a rubber or grit surface for engagement with the top of the stack, and may be a roller, a wheel or an endless belt. Alternatively, or in addition, the surface may be grooved, or may have radially-projecting teeth, for engaging the top of the stack to effect discharge of the leaves from it.
- The rate of discharge of the leaves from the stack may be regulated simply by control of the rate of rotation of the rotatable member. When the leaves are packaged together in billets or wads, the billets or wads may be placed as a stack directly under the rotatable member. Rotation of the rotatable member in this case may be effective (for example, by means of one or more blades or other projections on it) to split open the packaging and thereby release the contained leaves for discharge leaf by leaf under the action of the rotating member.
- Methods and machines for spread-distributed discharge of paper or other leaves from a stack, all in accordance with the present invention, will now be described, by way of example, with reference to the accompanying drawings, in which:
-
FIG. 1 is a front perspective view of a first example of leaf-discharge machine according to the invention; -
FIG. 2 is illustrative of the leaf-discharge machine ofFIG. 1 in side elevation; -
FIG. 3 is illustrative of a form of feed-roller used in the leaf-discharge machine ofFIGS. 1 and 2 ; -
FIG. 4 is a front view of another example of leaf-discharge machine according to the invention; -
FIG. 5 is an exploded view of the main components of the leaf-discharge machine ofFIG. 4 ; and -
FIG. 6 is a sectional view illustrative of a feed-roller assembly of the leaf-discharge machine ofFIG. 4 . - Referring to
FIGS. 1 and 2 , the leaf-discharge machine 1 of the first example has arectangular casing 2 with a front-wall 3, a back-wall 4 and opposite side-walls 5 and 6. An elongate sheet-metal guard 7 having a horizontal, open-slot mouth 8 extends across the front of thecasing 2 bridging a large rectangular aperture 9 in the front-wall 3. Theguard 7 is in this respect carried at its two ends by two triangular carrier-brackets 10 respectively (only one shown inFIG. 1 ) that are mounted on opposite ends of ashaft 11 which project from within thecasing 2 through guide-slots 12 in thewalls 5 and 6. - The
shaft 11 extends within thecasing 2 between downwardly-turnedbrackets 13 at the front of aplate 14 that is coupled to the back-wall 4 through a sliding pivotal connection. The sliding pivotal connection is formed by arod 15 which projects rearwardly from theplate 14 to extend through ahole 16 in the back-wall 4. Sliding adjustment of therod 15 within thehole 16 enables pivotal movement of theplate 14 to take place while allowing vertical movement of the front of theplate 14 and the carrier-brackets 10 with attachedguard 7, guided by theshaft 11 within thevertical slots 12. - A feed-
roller 17, illustrated inFIG. 3 , is rotatably-mounted on theshaft 11 and by virtue of the pivotal freedom of theplate 14, rests on the top of a stack of paper leaves loaded into the bottom of thecasing 2; the top of the stack is represented inFIG. 2 by the chain-dotted line S. Anelectric motor 18 mounted on theplate 14 drives theroller 17 via atoothed belt 19 which engages theroller 17 within a central, circumferential recess 20 (FIG. 3 ). Rotation of theroller 17 peels off the paper from the top of the stack leaf by leaf for discharge through themouth 8 of theguard 7 at a rate dependent on the speed of themotor 18. As leaves are peeled off, theplate 14 pivots down to maintain theroller 17 carried by thecarrier brackets 10 guided by theslots 12, to move vertically down in contact with the top of the stack. - The speed with which the
motor 18 drives theroller 17 is regulated from a DMX (digital multiplex) lighting-control system (not shown) as used in a theatre. This can be very precisely controlled as required, between the extremes of very slow, to give a gentle discharge, and very high, to give a furious discharge of the leaves. - The machine of the present example includes a counter-balance system so that the pressure of the
roller 17 on the top of the stack can be adjusted. In this regard, the externally-projecting ends of theshaft 11 are each connected bywire 21 viarespective pulleys 22 to leadweights 23 housed withinvertical tubes 24 mounted on the side-walls 5 and 6 of the case. By suitable choice of theweights 23, the pressure exerted by theroller 17 can be selected to be very light, as required for example where sheets of tissue are to be distributed, or heavier as appropriate for example where distribution of leaflets is required. The paper or other leaves distributed by the machine may be, for example, of A4 or A5 size, and where leaves smaller than this are involved, packing pieces are desirably utilised to keep the leaves straight-on to theroller 17 anddischarge mouth 8. The surface of theroller 17 used is appropriate to the leaves to be distributed, and may be rubber or grit; it may possibly where appropriate, be grooved affording projecting ridges or lands to peel off the leaves more effectively from the top of the stack, and may have projecting teeth. - A rotating wheel or endless belt may be used in place of the rotating
roller 17. Furthermore, rather than using thepivoted plate 14 to carry themotor 18, it may be carried at the front of thecase 2 with, and directly geared to, theroller 17. More particularly, themotor 18 may be mounted above theroller 17 on carrier brackets guided by theshaft 11, and in these circumstances a second horizontal shaft with its two ends projecting through the guide-slots 12 may be provided above theshaft 11 to maintain vertical movement of theroller 17 onto the top of the stack. - Another example of leaf-discharge machine will now be described with reference to
FIGS. 4 to 6 . - Referring initially to
FIGS. 4 and 5 , themachine 31 in this construction has arectangular casing 32 with afront aperture 33 that is bridged by afixed plate 34 at the top and by a guard-plate 35 that is movable laterally up and down the front of thecasing 32. In this regard, the guard-plate 35 is bolted to a carrier-plate 36 that is mounted at its two ends within theaperture 33 on carrier-brackets brackets ears 39 which project from within thecasing 32 through vertical guide-slots 40 of thecasing 32. Theears 39 extend sufficiently lengthwise of theslots 40 to constrain thebrackets plates - A
roller 41 is mounted between thebrackets plate 36. As shown inFIG. 6 (from which theplate 36 is omitted), theroller 41 is of a hollow tubular construction with a closedend 42 that is rotatably mounted on a stub-shaft 43 that projects from thebracket 37. Anelectric motor 44 andgearbox 45 which are mounted on thebracket 38 project into the other, open end of theroller 41, and theoutput shaft 46 of thegearbox 45 is secured to aplug 47 inside theroller 41. Theplug 47 is secured to the inside of theroller 41 by a grub-screw 47 so that theroller 41 rotates under drive from themotor 44. As with theroller 17 of the first example of machine, the speed of theroller 41 may be regulated from a DMX system. - The
roller 41 rests on top of a stack (not shown) of paper or other leaves loaded into thecasing 32, and as guided by theears 39 of thecarrier brackets slots 40, remains in contact with the top leaf as the leaves are peeled off one by one from the top by the rotatingroller 41. A counter-balance system for controlling the pressure of theroller 41 on the stack, and corresponding to the counter-balance system of the machine of the first example described above, is operative viawires 48 that are attached to the carrier-brackets respective pulleys 49 to leadweights 50 located within vertical tubes 51. - The leaves peeled off one by one from the top of the stack by the rotating
roller 41 are discharged through an open-slot mouth 52 of the guard-plate 35. Depending on the weight of leaf to be distributed, it may be necessary or desirable for enhancing its discharge to adjust slightly the lateral position of themouth 52 relative to the rotational axis of theroller 41. This can be done by adjustment of the registration of the guard-plate 35 with the carrier-plate 36 in bolting the two together.
