14 Claims.

This invention relates to a label cutting machine, and its object is to provide an improved mechanism for accurately and rapidly cutting cloth or fabric label strips into separate labels. Such label strips have woven, embroidered or printed thereon a succession of like indicia or identifying marks indicating the trade name of the articles to which they are to be applied, or the name of the maker of the articles or of the dealer. Although such labels are of approximately equal lengths, their lengths vary somewhat because of inaccuracies in the process of manufacturing them. The strip must be cut accurately between the labels on the strip so that such matter will be exactly centered on each of the severed labels. In order to accomplish this result, it is necessary to provide a positive propelling mechanism for intermittently feeding the strip longitudinally, which is coordinated with a cutter for severing the strip transversely and which can be adjusted with great nicety to feed labels of different lengths. More specifically, the object of this invention is to provide a motor-driven machine which will perform the aforesaid functions rapidly with a minimum of attendance. To that end I have arranged a manually operable mechanism for causing the machine to stop when ever desired, and for arresting its parts in positions in which adjustments can be made rapidly, or new material to be cut may be inserted. The arresting mechanism is arranged to lock the parts in such positions for the sake of safety.

I have arranged also to prevent injury to the cutter and other parts of the machine whenever foreign matter is brought into it by the strip, by providing an automatic electro-mechanical stopping arrangement.

These and other objects of the invention will appear in the following specification, in which what I now consider a preferred embodiment of the invention will be described and its novel features defined in claims.

Referring to the drawings,

Fig. 8 is a sectional side elevation of a portion of the machine, showing some of its parts on an enlarged scale. This section is taken on the line 8-8 of Fig. 2;

Figs. 9 and 10 are sectional views of parts shown in Fig. 8, the sections being taken on the lines 9--9 and l0lll of the latter figure;

Fig. 11 is a front end elevation of the clutch to the bed. 40 is the main shaft of the machine Fig. 1 is a side elevation of a machine which of the parts shown in Fig. 2 are electrically interconnected;

Figs. 4 and 5 are sectional side elevations of the machine shown in the preceding figures, the sections being taken respectively on the lines 4--4 and 5--5 of Fig.2;

running in bearings on the

plates

23, 24. 49 is a hand wheel on an end of shaft 40. 25 is a clutch member rotatively mounted on the shaft 40 and having teeth 25 on one of its ends. 2! is a gear formed integrally on the clutch member 25 in mesh with a pinion 28 which extends from a pulley 29 on a stub shaft 30. A belt 3| connects the pulley 29 with a pulley 32 on the shaft of a motor 33. The motor is slidably supported in guides 34 under the bed 20. 35 is an electric switch for the motor current.

41 is a clutch member splined to the shaft 40, as at 42, and slidable thereon. This member has teeth 43 which cooperates with the teeth 26 when pressed into engagement with them by a spring 44. 45 is a groove in the member 4|, in which are diametrically opposed

rollers

46, 46 near one end of a bifurcated plate on lever 41, the other end of which is pivotally mounted in a bracket 48 mounted on the bed 20.

50 is a bar disposed at right angles to the axis of the shaft. One end of this bar is slidably mounted in a bearing 5! on the bed 20. Its other end is connected to the core of a solenoid 52, which is affixed to the bed 20. Intermediate its ends, the bar slides in a groove in the bracket 48, as shown at 53 in Fig. 11. A notch 54 is cut in the side of the bar opposite the groove 53, one end of which forms an inclined cam surface 55. 5B is a rod pivoted to the lever 41 at 51 and 3 extending into the notch 54 when the clutch members and M are in engagement, and extending to the side of the bar 58 when they are out of engagement, as shown in Figs. 11-13.

A hand lever 36 is pivoted to the bed 28 at 31. This is connected to the bar 50 at 38. When.

the bar 50 is moved to the left, as viewed in Fig. 2, the clutch member 4| will be forced into engagement with the motor-driven clutch member 25by the spring 44, and the shaft 40 will be driven by the motor 33. The clutch members may be separated by swinging the hand lever to the left, as viewed in Fig. 2, to move the bar to the right.

This will cause the cam in the side of the' bar to engage the proximate. end. of the rod 55 to move the lever 41 and the clutch member 4! against the action of the spring, to the posi tions in which they are shown in Figs. 11-13 and disconnect the motor-driven clutch member.

Strip fecal-50 is a disk affixed to the shaft 40 near one of its ends and in frontof the plate 23. An undercut groove 5|,is cut diametrically across the outer face of this. disk. 62 is. ablock slidably mounted in thegroove, from which a pin 63 projects. 64 is an; adjusting screw, which passes through a. threaded hole in theblock. E5 is a toothed sector, pivoted at 65 to the plate 23. In it is a radially disposed elongated slot 6,1, into which the pin 63 extends. By this arrangement rotation. of the disk imparts a reciprocating movement to the sector when the pin 63 is out of axial alinement with the shaft. The stroke of this reciprocation can be adjusted from zero to the full length ofthe toothed are of the sector.

The sector teeth engage those of a pinion I0 loosely mounted on a shaft I I which projects from the plate 23. This pinion is rotated in opposite directions by the reciprocationoi the sector 65. I2 is a gearon the shaft It, on which are pawls 13, which are spring-pressed into engagement with the teeth of pinion 'IIJ (see Fig. 8.). By this arrangement, an intermittent rotation is imparted to thegear 12. Agear I4 afiixed to. a shaft i5 is in mesh with the gear I2. One end'of shaft I5 runs in a bearing supported on the plate 23. It extends through a bracket "I6 on the outer edge of the feed table 22, and has; a knurled knob 11 affixed. I8 is another gear afiixed to the, shaft inside the bracket 16' and spaced from the gear 14;. Between thegears l4 and I8 is a feed roll 19 (Fig. 6).

8D is a housing affixed to the feed table and adlustably supporting a shaft 8! parallel with and above the shaft I5. Gears 82, 83 on shaft 8I respectively engage the

gears

14 and 78, and betweenthem is a feed roll 84 (Fi 6 Theshaft BI runs in bearings in side plates 85 85, which are affixed to a shaft 86 mounted on one side of the housing 8'! is a rocker arm affixed to shaft 86. On one of its ends is a knob 88, by means of which the rocker. arm may be depressed to raise the side plates 85, and re-. lease'the pressure between the feed rolls I9 and 84.

90 is a connecting rod pivotally connected to the other end of the rocker arm 8'! at 39 (Fig. 7) The lower end of the connecting rod is connected at 9| to one end of a lever 92, which is pivoted at 93 to. the plate 23. Intermediate the ends of lever 92 is a roller 94. 95 is; atension spring between the connected' ends of the rod 96 and lever 92 and the bed Ml. This tends to move the feed roll 84 toward the iced roll I9, and this movement is limited by the engagement of;

to of one of the labels.

the roller 94 with the periphery of a cam wheel 96 on the main shaft 40. The cam wheel has a slightly raised portion 97 which, by engaging the roller 94, releases the pressure between the feed rolls during a part of the cycle of operation of the machine.

I00 is a reel rotatively mounted on brackets I01 projecting from the bed 28, for holding a roll A of label strips. The strip is led through a tensioning device, designated generally by the reference numeral Hi2, which comprises angularly spaced pins H33, around which the strip passes, projecting from a disk I04, which is mounted eccentrically on a shaft I85 rotatively supported in a bracket ififi on the end of the feed table 22. A pulley It? is affixed to the shaft I85, and a weight W8 is suspended from the pulley 101 by a cord. This arrangement imposes a resistance to the passage of the strip through it.

The strip is led across the top of the feed table to. and between the feed rolls I9 and 34. On the feed table the strip passes between side guides I09, and lit, which are laterally adjustable to accommodate strips of difierent widths and are fastened to the feed table. On the side guide H8 is a longitudinal slot III, in which a head H2 is adjustably mounted. Its position is adjusted by means of a knob I13. 4 is a pin which projects from the head l 12 across thespace between the side guides. H5 is an arm of a bell crank lever on the pin H4, from the lower end of which a fiat blade H6 projects. This arm swings by gravity toward the feed table, and its downward movement is limited by an adjusting screw 1, which engages a projection from the side of the head I2 (see Fig. 8).

The operation of the strip feed mechanism is as follows: The strip is led from the reel I00 through the tensioning device I02 and across the feed table to the feed rolls I9, 84. It passes under the bladev H6, which is adjusted to touch the strip lightly. By depressing the knob 83 the feed rolls are. separated sufficiently to permit the insertion of the strip between them. Then when I the knob 83 is released the spring 95 pulls the feed rolls together to engage the strip. The strip may be then adjusted by turning the knob Tl.

When the clutch is closed the first movement of the feed rolls draws the strip along the length The blade H6, because it is inclined, prevents the strip from retracting beyond a desired amount. When the labels are embroidered on the strips the indicia thereon project slightly above the upper surfaces of the strips. With such strips the driving mechanism for the feed rolls is adjusted to feed the strips linear distances slightly greater than the length of the individual labels. Then, when the upper feed roll is raised automatically at the end of each feed stroke, or manually by depressing the knob 88, the tension device draws the strip back until its movement is arrested by a part of the indicia thereon reaching the blade H6. In some cases, cut-off lines are woven into the strips at 2 equal intervals to efiect this automatic adjustment of the position of the labels. When the. labels are printed on the strips the desired adjustment may be made by hand.

The cutting mechanism.A lever I20 pivoted at I2! on the plate 23 carries a roller I22, which projects into a cam groove I23 in the side of they cam wheel 96. During each revolution of the main shaft 40-, this lever is depressed. I24 is a stationary shear blade amxed to the plate 23 75 by a bracket I25, with its cutting-edge approximately level with the upper surface of the feed table 22. I26 is a shear blade pivotally mounted on the bracket I25. Both of the shear blades have crimping teeth. The movable shear blade is connected with the lever I by a connecting bar I21, which is made in two sections so that its length may be adjusted. A tension spring I28 exerts an inward pressure on the connecting bar to draw the two shearing blades together. The upper section of the bar I2! is connected with the movable shear blade I by a pin-and-slot arrangement at I29, so that the stroke of the bar may be somewhat greater than that of the shear blade.

Automatic stop.A shoe I30 is adjustably attached to the under side of the lever II5. This is set so that when the blade H6 is in contact with the label strip the lower surface of the shoe is in close proximity to the upper surface of the label strip. When any foreign substance is carried into the machine by the label strip, such, for example, as a pin interconnecting two label strips, it will contact the shoe I30 and raise the lever II5. I 3| is an arm extending from the pivoted end of the lever II5 to a normally open micro-switch I32. A conductor from a source of electrical supply, designated by in Figs. 1 and 3, is connected to the switch I32. Another conductor, I34, runs from the switch I32 to a normally closed micro-switch I35, which is connected by a conductor I31 to a terminal of the solenoid 52, the other terminal of which is connected to a conductor from the electrical supply. When the arm I3I is depressed, a circuit is closed through the solenoid 52, which pulls its armature and the bar 50 to the right, as viewed in Figs. 2-5, and by the mechanism previously described, opens the clutch. Then, a pin I38 on the bar 50 engages a spring I39 and opens the micro-switch I35 and breaks the solenoid circuit.

It has been shown that when the bar 50 is moved to the right by the hand lever 36 or by the solenoid 52, the clutch member M will be moved against the action of the spring 44, out of engagement with the clutch member 25. A roller I on a pin I4I which projects radially from the clutch member M will then travel in a path which will cause it to engage the upper part of a cam plate I42, which is pivoted in the bracket 48. When the clutch is first disengaged, the momentum of the parts connected with the main shaft 40 will cause the shaft to rotate until such movement is arrested by the engagement of the roller I40 with the cam plate. The parts on the main shaft or driven thereby are so positioned in relation to the roller I40 that when the movement of the shaft is thus arrested, the shear blade I26 will be raised, the feed rolls TI, 84 will be at rest, and the pressure between the feed rolls will be released, so that desired adjustments of the machine or of the label strip may be made readily without stopping the motor 33.

Safety loch-When the roller I40 is in engagement with the cam plate I42, the latter will be pressed to the right, as viewed in Figs. 11-13. The cam plate then engages a shoulder 58 on the rod 56, so that the spring 44 cannot move the clutch member M or the lever 41 to the left, even after the bar 50 has been shifted to the left. Thus, the machine is locked, so that an operator can make all desired adjustments without danger of having his hands caught in any moving part of the machine. This condition will remain until the roller I40 is moved away from its contact with the cam plate I 42, which can be done by turning the hand wheel 49.

The objects set forth at the beginning of this specification are accomplished by the mechanisms described.

Various modifications in construction, mode 0 operation, use and method of an invention may,

and often do, occur to others, especially after benefiting from knowledge of such a disclosure as that herein presented of the principles involved, but the invention itself is not confined to the present showing.
