Application filed April 13,1922. Serial No. 552,151.
signed to wrap asheet of paper or other Wrapper about a'packa e or carton, and it relates particularly to the means for conveying-the cartons orpackages through the machine andjpa'st the wrapping devices.
The objects of the invention are to provlde an lmproved package-convey ng means 7 which is constructed to firmly hold the package in position during its movement past the"wra'pping mechanism, and otherwise to improve the conveying mechanism of wrapping machines all as will be more fully hereinafter set forth. V p v In order to give an understanding of the invention I have illustrated in the drawings a selected embodiment thereof which will now be described after which the' novel features will be pointed out in the appended claims. I V V Fig. 1 of the drawings is a fragmentary view of the package-conveyer having my improvement applied thereto.
Fig. 2,,isan enlarged view showing the position of the parts as each package is delivered to the conveyer.
' Fig. 8, is a view similar toFig. 2 showing the position of the parts ata short interval of time prior to that in which they, assumed the position shown in Fig. 2. V The'mechanism herein'shown isdesigned to be used inconnectionwith a wrapping machine .having'the construction illustrated in my co-pending application Ser. No. 314,- 592. filed August 1, 1919. g The machine shown in said application comprises a belt for bringing the packages to be wrapped into the machine, a table or plate having an opening of a. size to receive the packages, means to deliver wrappers in position over the opening, means to force individual packages. through said opening thereby to fold awrap'per partially thereabout, endv folders for folding the ends of 5 each wrapper and apacka-ge conveyer for taking packages after they have been moved "through said opening and carrying said packages past the end folders, which operate to fold the ends of the wrapper against the 1 package. i
In order. that the wrapping operationmay be satlsfacto-rily performed it is desirable that after the wrapper has been folded about the package by applying the package through the opening in the table, saidwrapper should be heldfirmly against the sides of the packages while the'conveyeris carrying thepartially wrapped package past the end folders, for if during this latter opera- I tion the wrapper is loosened from the packs wrapper will be loose o-n the. the wrapping is completed.
' My present improvement provides means for holding the wrapper tightly against the sides of the package while the latter is being "moved by the conveyer past the end-folding devices so that when the end folders operate on the ends of the wrapper the portions thereof which engage the sides of the packageor'bulges out from the sides thereof the package when age will beheld wrapped tightly about the 7 package.
Inasmuch as my present inventionrelates simply to the conveying mechanism I have only shown herein a sufiicient portion of the to be understood. In the drawings 1 indicates a portion of the frame which supportsthe operating mechanism and 2 indicatesin cross section the feeding-in belt which conveys the packages into'the machine. I
wrapping machine to enable the invention ,As the packages are carriedv along by the I Com-eye 2 th y on y a r cating transferrer 3' which transfers them from the conveyor 2 onto a vertically-moving elevator 41-, said elevator takes the individual 'packages and forces themupwardlythrough an opening 5 formed in'a table'6. The wrappers are fed into position across the opening 5 and beneath the table 6 by mechani'sm such as illustrated in my above-mentioned application so that during the upward movement of the elevator 4 the package 8. is':carried against the wrapper, and the package 8 and wrapper are forced 'up through the opening 5 thus folding the wrapper about the body of the package 8. When the package is fully elevated" as shown in Fig. 2,. a reciprocating folder 7 2 which engages the opposite side age 8 from that whlch is engaged by the moves forwardly to tuck the edge of the wrapper underneath the package8, as shown in Fig. 2. The package at this time with the wrapper folded about the body thereof and with the ends of the wrapper projecting beyond the body, as shown in Fig. 4:, is then taken by the package conveyer and moved over the table 6 to the end-folding devices which fold the ends 9 of the wrapper about the package. As stated above the present invention relates to the construction of the package conveyer and has for its object to provide a. novel conveyer arranged so that the wrapper 10 will be. held tightly wrapped about the body of the package while the latter is being conveyed to the end folding devices.
The package conveyer comprises an endlessbelt or chain 11 passing around sprocketwheels 12 and 13 carried. by the frame and one of which is positively driven, and a plurality of pusher'st 14 secured to the chain 1-1 at intervals, said pushers operating to take the individual packages as they are delivered through the opening 5 by the elevator t and feed them past the end-folding. devices, (not shown) and toward the left in Fig. 1. a
In order to hold the wrappers 10 closely wrapped about the body of the package while they are being acted upon by the pushers 14 I provide a clamping member 15 which is associated with each pusher and of the packpusher so that while the package is being conveyed by the conveyer it will be firmly held between the pusher and the clamping member 15. Each pusher is secured to a block 16 connected to a linkof the chain and the clamping members 15 are pivotally connected to the block 16, as shown at 17 Means are provided for swinging each clamping member up out of the way while the corresponding pusher is approaching the package 8 that is being elevated through the opening 5 so as to allow the clamping member to pass over the package, and as soon as the pusher has engaged the package the clamping member is swung down into engagement with the opposite side.
To accomplish this each clamping member is provided withan arm 18 carrying a roll 19 which is adapted to engage a cam member 20-fast tothe frame and located over the opening 5. This cam member 20 has the two inclined faces 21, 22 and the construction is such that as the pusher approaches the package 8 being elevated. through the opening 5 as shown in Fig. 3, the roll 19 engages/the cam face 21 thereby swinging the clamping member upwardly intoa horizontalposition above the package, in which position it does not interfere with the movement: of the package through" the opening 5. The clamping member is held in this position until it has been carried over the package 8 and the pusher is about to engage the package, at which time the'roll 19 passes down the inclined face 22 thus allowing the clamping face to swing downwardly against the package under the influence of the spring 23. By the time the pusher has engaged the package the roll 19 is passed off from the inclined face 22 and the package is firmly held between thev pusher and the clamping member and continues so held while it is fed along past the end folders, not shown.
In order to still further assist in wrappingthe wrapper 10 closely about the body of the package I provide a stationary guide member 24.- against which one face of the package engages as it is carried upwardly by the elevator a and said guiding member has an. arm 25 extending laterally therefrom which is situated to engage the top ofthe package when the elevator 4: is at the upper end of its stroke, as seen in Fig; 2.
26 is a pivotally mounted finger adapted to engage one side face of the package as the latter is elevated by the elevator 4: and with this construction the package will be firmly held between the guide 24 and finger 26 while it'is being raised and when it is in m position to be engaged by the pusher f the 'wrapper will be held closely to the sides of the package by said guide 24, the arm 25 and pivoted finger 26.
The clamping member 15 is preferably provided with a laterally-extending finger 27 adapted to engagethe top of the package when the clamping member assumes its operative position, and, therefore, as soon as the pusher 4L engages the package the wrapper will still continue to be tightly held against the body of the package by the pusher, the finger 27 and the clamping member 15. 1
As the package is moved to the left Fig. 1 by the conveyer the finger 26' swings backwardly and the edge of the wrapper is folded under the package during the move ment of the latter.
By this means the wrapper is held firmly folded about the package while it is being conveyed to and past the end folders '75 by the conveyer so that when the end. folders. which are not herein shown. as they form no part of the present invention, operate on the ends of thewrapper to fold the latter about the ends of the package 8, the portion of the wrapper surrounding the body of the package will be held firmly in contact therew'th. and a tightly wrapped package wiii result.
After the: package: has been completely wrapped it is delivered. to a pair of endless belt devices, one of which. isfsho'wn. at 28, which take the packages and. discharge them from the conveyer. When the package is being acted on by the the clamping member is removed from engagement with the package so as not to 'in-' terfere with the discharge of the package from the conveyer and this is accomplished by a cam member 29 constructed similarly to the cam member 520 and arranged to swing each clamping member into horizontal position thereby releasing the package so that it can be removed from the conveyer by the endless belt devices 28. r
The finger 27 is 'adjustably mounted on the clamping device to provide for operating on packages of different sizes and the arm is also adjustably secured to the guide 24 for the same purpose. Similarly the clamping member 15 can be ad usted toward and from the pusher to accommodate different sizes of packages and this is provided for by pivoting the clamplng memis adj ustably run thereof, means to deliver packages singly into position to be engaged by the pushers, the latter operating to move the packages over the support, a clamping member associated with each pusher and adapted'to engage the front side of the package engaged by said pusher, each clamping member being mounted to swing about a horizontal axis,
and means to swing each clamping member into position to clear a package which has just been delivered to sald support and while the corresponding ipusher is being brought into operative engagement with said package, and then swing said clamping member into position to clamp said package to the pusher as the latter engages the package to move it forward.
2. In a wrapping machine comprising means to support packages-to be wrapped, an endless chain element having one run operating above said support, pushers carried by said element and depending from said run, and means to deliver packages singly into position to be engaged and fed forward by said pushers, the combination with said endless chain elements and push ers, of a clamping member associated with each pusher and mounted to swing about a endless belt devices 28 extending finger package.
wrapped are horizontal a xis, and means to swing each clamping member upwardly to pass over a package which has just been delivered to said support, and then'to swing said c'lamp-- mg member downwardly into position to clamp said package to the pusher as the latter engages the package to move it forward, said clamping member having a laterallyto engage the top of the 3,111 a wrapping machine, the combination with wrapped are supported, of an endlesscarrier having one run above and parallel to said support and situated above the packages supported thereon, pushers mounted on said carrier and arranged to depend from said,
