tudinal-type semiautomatic packaging machines in which the ~ront plate 4 is horizolltally disposed.
In conventional packaging machines o~ the type described, an article when placed on the worktable often obstructs access to the band insertion member 8 if the article is large in size, and it therefore becomes impossible to insert the end of the band. This necessitates the troublesome operation of adjusting the height of the~worktable 7 in order to expose the band insertion member 8. Nevertheless, it is still impossible ln some cases to package a large article since the extent to which the worktable can be adjust-ed in height is limited. In addition to these dis-advantages, the conventional packaging machine has still another de~ect in that it is necessary to re-operate the band delivery mechanism in cases where the delivered length of band is insuf~icient and thus too short to be wound around the article. This is be-cause the band is delivered only by constant amounts through the use of a timer.
BRIEF SUM~ARY OF THE INVENTION
It is a general object of the present invention to avoid the disadvantages of the conventional pack-aging machines such as described above.
A specific object Pf the present invention is to ~ ~37.~,~
provide a band guiding mechanism in a packaging machine capable of efficiently packaging articles regardless of their size.
According to the present invention, the foregoing and other objects are attained by a band guiding mechanism which includes band guiding flaps adapted to be opened and closed, the latter including a drive roller and driven rollers which come into sliding contact to guide a band from an insertion member to a control unit equipped with means for suitably manipulating the band so as to package an article.
Thus, the present invention is generally defined as a band guide mechanism for a machine of the type including a frame body, a band delivery mechanism, a band insertion member, a worktable on which an article to be packaged is placed, and means for tightening, fusing and severing the band which has been wrapped around an article placed on the worktable. The band guide mechanism includes a control unit housed in the frame body.
Means define a band guide channel having a band insertion end adjacent the insertion member and at least one movable wall which is movable between a closed position and an opened position whereat a length of band may move ~ransversely outwardly of the channel. A drive roller is mounted adjacent the band insertion end of the channel and at least a portion of the periphery of the drive roller extends into the channel. A driven roller mounted for movement with each of the at least one movable wall has at least a portion of its periphery extending into the channel for opposed frictional engagement with the periphery of the drive roller in the closed position of the movable wall so as to thereby drive a length-of band disposed between the periphery of the rollers along the channel.

DETAILED DESCRI~TION OF THE INVENTION
Referring now to Figs. 2 and 3 for a detailed description of a preferred embodiment of the present invention, a packaging machine frame designated gen-erally at 10 houses a control unit C which includes y various well-known mechanisms required for packaging, such as a band bonding mechanism or the like. The f~nt plate 11 of machine frame 10 includes a channel 12 at approximately the center thereof, and a band in-sertion member 13 is attached to the top of the frame at the upper end of the channel 12. A band guiding flap mechanism 20 extending from the band insertion member 13 to the control unit C housing the required pac~aging mechanisms, is openably and closably pro-vided on the channel 12, the band guiding flap mech-anism 20 beinB mounted such that its lower end con-fronts the upper end of a sliding table 14, as shown in ~ig. 3.
; -5-37~3 According to the arrangement of the band guiding flap mechanism 20, as shown in more detail in Figs.
4 through 7, brackets 24, 24 are fixedly secured at the sides of respective flap-shaped opening-closing pieces 23, 23 whose sides on the band insertion end are bent. The brackets 24, 24 axially support re-spective driven rollers 25, 25 in a freely rotatable manner and allow the driven rollers 25, 25 to face in-wardly of the opening-closing pieces 23, 23 through notches 26, 26 formed therein. The end of a bandway 27 is bent and ~the bandway attached to the frame lO by -fixedly securing the bent portion thereof to the frame ;
via a hinge or the like. A drive roller 32 is provided on a shaft 31 having a pulley 30 connected to a drive mechanism via a belt 29, and is faced inwardly of the opening-closing pieces 23, 23 through a notch 28 in the bandway 27 so as to come into sliding contact with the driven rollers 25, 25. Further~ the band guiding ~lap mechanism 20 is arranged to be freely opened and closed by mean~ of hinges 33, 33 provided on the open-ing-closing pieces 23~ 23 which are connected to re-spective legs 34, 34 projecting from below the band-way 27, the opening-closing pieces 23, 23 being biased closed by a coil spring 35.
Fig. 4 illustrates the band guiding flap mech~
anism 20 in the mounted state. Specifically, the band guiding flap mechanism 20 is attached to a supporting member 16, extending from a machine rack 15, by means of a nut and a screw 43 fixedly secured to the bottom of bandway 27 of the band guiding flap mechanism. The open, lower end of the band guiding flap mechanism 20 is arranged to face the sliding table 14.
The packaging machine further includes a work-table 18, pedestal 19 and supporting plate 36 for the shaft 31.
The.actions and effects of the packaging machine constructed as described above will now be described. I
Referring now to Fig. 3, a band B, a fiXed amount Or which has been delivered by a timer, is wrapped around an article W and the end of the band is inserted into the insertion member 13, whereupon the band B
is embraced between the drive roller 31 and driven rollers 25~ 25 which are rotating in sliding con-tact with the drive roller 31.` The band therefore advances into the band guiding flap mechanism 20 and soon reaches a band strip guide, not shown, at the back of the sliding table 14 of the control unit C.
At this time a well-known limit switch or the like is actuated to immediately operate a band tightening mechanism. At the same time as the band-tightening ' ' ` ` ~ ~
.
7;~
operation? the flaps 23, 23 of the band guiding flap mechanism 20 are pushed open so that the band B flies out from therebetween. Thus, the band B is completely wound around the article W and tightened and subse-quently severed and fused to complete the packaging operation. After the band has reached the control unit C, the steps up until the tightening of the band are instantaneously performed through electronic con-trol even in cases where the drive roller 32 is arrang-ed to constantly rotate. As a result, the band will not jam in the-band guiding flap mechanism even if the band is delivered to an excessive degree. The band tightenlng operation also will not be affected.
In the above arrangement, the driven rollers 25, 25 are provided at the end of a single band guid-ing flap mechanism and the drive roller 32 is mounted in sliding contact with the driven rollers so as to from a single continuous band guiding path ~rom the band insertion member to the lower surface of the sliding table 14. However, in an example of another possible arrangement, the band guiding flap mechanism 20 may be cut o~f below the driven rollers 25, 25, a band auxiliary feed mechanism adopted wherein the driven rollers 25, 25 and driye roller 32 are mounted ~ ~372;~
~ithin the frame or outside the fr~me so as to freely contact and separate from each other, with another band guiding flap mechanism being proYided in such a manner that its opening portion faces the band exit side of the band auxiliary feed mechanism. In other words~ it is possible to adopt a structure wherein a band auxiliary feed mechanism and band guiding flap portions are separately arranged in a continuous manner.
Such an arrangement allows the length of the other band guiding flap portion to be suitably modified even in t~e case of packaging machines ha~ing differ-ent lengths from the band insertion portion to the control unit C. It is therefore possible to work the present invention is a simple manner.
It is also possible to adopt an arrangement in which the rotation of the drive roller 32 is controlled by a limit switch(not shown) provided at the band inser-tion member 13, so that the band delivery mechanism of the control unit C is re-actuated by the insertion of the band, and then shut off when the end of the band reaches the control ur,it C. If this construction is adopted, it is possible to eliminate the operation of depressing a switch pro~ided on the frame for the purpose of re-actuating the band delivery mechanism e~en if the already fed band is not sufficient for '37~?d~
wrapping around a large article.
In accordance with the band guiding mechanism of the present invention as described above, the in-sertion of the band end can be greatly simplified, and articles of any size can be packaged without ad-justing the height of the worktable. It is also possible to guide the band toward the control unit C after in-serting it from any position. In other words, the band can be inserted from underneath the frame, from the horizontal direction, or from a position in which the band guiding flap portion is disposed close to the frame or re~ote therefrom. In addition, if the band guiding flap mechanism 20 is detachably mounted on the machine rack or the like, maintenance and in-spection of the control unit C and the setting of the band become very simple operations. These advantages permit a simple and rapid packaging operation not heretofore possible in the conventional semiautomatic paclcaging machines.
