Description

Patented July 2s, 1939 UNITED STATES PROPULSION MECHANISM FOR CONVEYEBS Curt G. Joa, Sheboygan Falls, Wis., assignor to Curt G. Joa, Inc., Manitowoc, Wis., a corporation of Wisconsin Application August 25, 1938, Serial No. 226,625
9 Claims.
This invention relates to improvements in propulsion mechanism for conveyers. More particularly stated, the invention relates to a device for `pulling a web of gauze or the like in which objects may be enfolded.
The invention is of particular utility in the manufacture of sanitary napkins. The present application is a continuation in part of my application 54,669, filed Dec. 16, 1935 which has matured into Patent No. 2,131,808, Oct. 4, 1938, and relating to a sanitary napkin machine.
The object of the invention is to provide means whereby a web may be pulled uniformly in a straight line Without slippage and without damage to a soft pa'd or other object which may be enfolded in the web. Other objects will appear from the following disclosure.
In the drawings:
Figure 1 is a view in side elevation of a, propulsion device and cut-off mechanism as used in a sanitary napkin machine and representing one embodiment of this invention.
Figure 2 isa plan view of the structure shown in Fig. 1.
Figure 3 is a view partially in plan and partially in section showing a modified embodiment of my invention particularly adapted for use where the tension to be exerted by the propulsion device is very great.
Figure 4 is a view taken in section on the line 4 4 in Fig. 3.
Figure 5 is a view taken in section on the line 5-5 in Fig. 3.
Figure 6 is a fragmentary detail view in perspective of one of the pressure blocks used in the device illustrated.
Figure '7 is a fragmentary detail view in perspective of one of 'the mounting plates used to apply pressure in the device shown in Fig. 3.
ALike parts are represented by the same refer-- ence characters throughout the several views.
In sanitary napkin machines and in other devices where a web of gauze or other material has to be pulled for a considerable distance through the mechanism, the propulsion device which does the pulling must be capable of developingvery substantial tension. where the propulsion device operates in synchronism with a cut-off mechanism so that any slippage which may occur between the propulsion device and the web will result in displacing the cut from its desired location in the web. Yet it is also necessary to avoid putting pressure on the web at points where relatively soft pads or This is particularly true A other articles may be enfolded therein and may, perhaps, be damaged by undue pressure.
In the device herein disclosed, a continuous web 8 of gauze in which at spaced intervals pads 9 are enfolded is shown, by way of example, as the type of web for the propulsion of which my improved mechanism is well adapted.` 'I'he web of gauze, between the enfolded pad, is subjected to the pressure of opposed pressure surfaces of a pair of lconveyers I and II. In the device shown in Figures l and 2, the conveyor I I constitutes an endless belt operating over pulleys I2 and I3 and supported on a conveyer table I4 at the point where pressure engagement of the gauze occurs.
The conveyer I0 comprises a pair of spaced chains I and I6, corresponding links of which are connected by pressure blocks I1 arranged in series to constitute mutually spaced flexible pressure pads. As shown in Figure 1, this arrangement readily permits the blocks to pass about the sprockets I8 and I9 while maintaining them in closely adjacent positions throughout the series when engaged with the gauze.
The number of pressure vblocks employed is such that the length of each flexible padwill correspond substantially exactly to the spacing between the absorbent pads 9 which are enfolded in the gauze web 8. Thus each of the pressure pads I1 of the conveyer will engage only the unfilled portion of the gauze, clamping the flat portion of. the gauze web tightly to the underlying belt II. To the extent that the belt II is relatively soft, the individual blocks Il will tend to slightly embed themselves in the belt and the tension which can be exerted by the device may be increased If the distance between successive absorbent pads 9 is increased or decreased, a different conveyer I0 will be substituted to have the correct number of pressure blocks to fit the space between the pads. Thus all pressure on the absorbent pads will be avoided and yet a very substantial tension will be rectilinearly exerted upon the gauze to pull it through the mechanism toward the cut-off knife 2,0 and its co-acting stationary shear 2|. l
In the device shown in Figures 3 to 7 the gauze web 8 and the enfolded pads 9 are preferably on edge instead of being horizontally disposed. This fact, and the desire to exert an even greater tension on the gauze led to the development of the special design here illustrated.
At one side of the path of the gauze, I provide upper and lower sprockets at 28 and 2l.
Attheothersideofthepatiioftliega,
I provide upper and lower sprockets 30 and 8|.
v'I'heehainll which operates oversprocketll hasitslinhconnected by pintlesll whichare extendedtoses'vealsoaspintlesfortheoonnectionofthelinksofchainll,whichoperates over lthe lower sprocket 2l. Similarly, the chain Il which operates over upper sprocket Il has its links connected by pintles which are extended at to serve also the linksof the chain l1 which. operate over the lower sprocket Il.
` Upon the pintles Il and It between the respective upper and lower chains are mounted the pressure blocks 3l and one of which is shown sepablock I. carried by the other set of chains at the other side of the gauze path. 'I'hus when the gauze is engaged between the blocks'of al- -ternating sizes, the gauze is corrugated or convoluted in such a way that the slippage thereof between the pressure blocks is virtually impossible. Therefore, a great deal of tension or pully can be exerted by the device provided the blocks are held in nrm pressure engagement upon the gauze. i
' Such'engagement is assured bythe pressure bars l. which are flexibly jointed and resiliently supported by the compression springs 4i at each joint. The bars are mounted in slots 42 of upstanding guide members 43 disposed at each side of the path of the gauze. Sockets at M in guide members Il receive the compression springs 4i. 'Ihe links of the respective chains ride on the marginal surfaces' of the jointed bars 40, thus receiving'the pressure of `springs l4i and transmitting such pressure through the pressure blocks to the gauze.
In this device the sets of pressure blocks on one conveyer system register exactly with the sets of pressure blocks on the other conveyer system to engage only that portionl of the gauze which is intermediate the enfolded pads s. Therefore.' when the.pads pass through the propulsive mechanism, they are entirely free of lateral pressure as clearly indicated in Figure 5.
It will, of course, be understood that in each instance means is provided for positively driving the propulsion conveyers `as desired. 'I'he driving connections are fragmentarily illustrated in Figures 1 and 4 but4 inasmuch as they may be varied as desired and constitute no part of the present invention, they are not described in detailhere.
