Conventionally, in label pasting devices,
As shown in the above publication, a device is known in which a feed wheel is provided with a one-way clutch for driving the feed wheel for feeding the support material web.

This one-way clutch seems to be suitable for feeding the supporting material web, but even if the precision of the feed wheel and one-way clutch is improved, there will still be a gap due to backlash (or play), and the gap due to backlash will gradually increase. However, it has the disadvantage that it gradually accumulates until it is no longer possible to advance the label into alignment with the print head. SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a label applicator with a feed mechanism that can always advance the label into a position in alignment with the printhead.

To achieve this objective, the labeling device of the present invention basically comprises means for peeling the pressure-sensitive label from the support web, and rotatably mounted teeth engaging said support web on its circumferential surface. a feed wheel for pulling out the web around the peeling means, a drive wheel, a first clutch member fixed to the drive wheel so as not to rotate, and cooperating with the first clutch member. a second clutch member fixed to the feed wheel so as not to rotate; and the feed wheel is rotatably mounted, and the drive wheel is displaceable in all directions; means for non-rotatingly attaching the feed wheel to the feed wheel; the attaching means moves the first and second clutch members to a first axial position so as to engage each other; and configured to move the villages axially apart from each other to an uncoupled position and to change the position of the drive wheel relative to the feed wheel to change the position at which the support web is advanced by the feed wheel to the stripping means. There is.

Therefore, according to the present invention, two clutch members are connected between the feed wheel and the drive wheel, and both clutch members are movable from the connected position to the unconnected position, and between the unconnected position, Misalignment of the support web can be corrected, thereby always advancing the support web into an aligned position.

A novel brake is included in the apparatus that applies a braking force to the composite web between where it is fed from the supply roll and the stripper.

The brake is actuated by the printhead through a pair of spaced contact portions. The contact portion operates the brake member. One of the contacts serves to move the brake member to an effective braking position, and the other serves to move the printhead to move the brake member to an ineffective position. The brake is active during the entire working cycle and until the end of the working cycle, except for the time when the feed wheel is driving the support web. The part can also be reversed and used with a member having one contact supported by the printhead and spaced apart contacts operated by it; It is preferable to have Movement of the brake member is initiated by the printhead, but an over-center mechanism maintains the brake member in its moved effective or ineffective position. The brake and the other brake, between which the composite web passes, are equipped with visible and elastic brake shoes so that the brake is self-energized.
It is preferable to arrange the brake members so that the distance between the brake members and the brake member increases. Next, a detailed description will be given with reference to the accompanying drawings.

The embodiments of FIGS. 1, 3-6 and the embodiment of FIG. 7 are suitable for use with the composite label 30 shown in detail in FIG. A composite web of label material 31 is transported releasably attached to a support or packing material 32. The label material 31 is laterally divided by transverse cuts 33 extending across the label material web and across the edges 34 and 35 of the composite web 30. "
Cuts 33, known as "buttcuts", separate the web 31 of label material into a series of end-to-end labels 36. The label material web 31 is
On its underside it has a coating of pressure sensitive adhesive 37 firmly attached to the web 31 of label material. Support web 32 has a thin film or coating (not shown) so that the label can be peeled from support web 32. Groups 38 of cuts are equally spaced along the length of composite web 30.

Each group 38 of cuts extends through the support material as well as the label material. Each group of cuts has an overall shape of 1-1, consisting of cuts 39S, 40S, 41S on the support material and linear cuts 39L, 40L, 41L on the label material. One end of cut 39S and cut 40S
The part of the web 32 between gives a brittle part 43S,

Handle portion 60 and frame section 54 have pivots 78 located at respective bosses 79 and 801. The pivot pivotably mounts an actuator 81, which is shown in the form of a lever. When a user grips handle 59 (assuming the user grips handle 59 with the right hand), the thumb passes around frame section 54 and actuator 81 engages the user's fingers. Actuator 81 supports a gear or gear portion 82 that meshes with gear 66 . A spring assembly 82', including a compression spring 83, urges the handle portion 60 and the actuator 81, forcing the actuator 81 in a counterclockwise direction (FIGS. 1 and 3). The spring assembly 82' is
This is shown in detail in FIGS. 45-48 of U.S. Pat. No. 3,678,745. Actuator 81 and gear 82 are initially in the position shown in solid lines in FIG. 3, but when operated they move to the position shown in dotted lines 81'. Feed wheel 64, pawl wheel 65
, the gear 66 is coaxially mounted on the post 74. Gear 66 has a pawl 83 that meshes with ratchet wheel 65 . When the actuator 81 moves from the solid line position to the dotted line position in FIG. 3, the gear 66 rotates counterclockwise until the pawl 83 passes the teeth 84 of the ratchet wheel 65, and when the actuator 81 is released, Spring assembly 82' drives gear 66 clockwise and pawl 83 drives feed wheel 64 clockwise. Clockwise rotation of the ratchet wheel 65 and thus of the feed wheel 64 is prevented by a flexible, resilient pawl 84' that engages the ratchet wheel 65. Lever 67 is in a plane offset from the plate of gear 66.

As best seen in FIG. 1, a lateral portion 85 connects gear 66 and bar 67 together. This lateral portion 85 passes through an arcuate slot 86 in the subframe 55. Lever 67 is connected to printhead 63 by a pin type coupler, generally indicated at 86. The pin coupler 86 is a pin and slot coupler consisting of an elongated slot 87 in the lever 67 and a pin 88 having a roller 89 received in the slot 87. Washers 90 and clips 91 hold rollers 89 to pins 88. Pin 88 is fixed to print head 63. As best shown in FIGS. 1 and 4, the print head 6
3 is provided with a pair of elongated parallel ball tracks 92 and 93. The subframe 55 has a pair of ball tracks 94
and 96 have been installed. Ball bearing rows 96 and 9
7 are the respective ball trajectories 92 and 94 and 93 and 9
5 has been accepted. This ball bearing row is
This is shown in detail in FIGS. 12 and 24 of U.S. Pat. No. 3,698,745. The ball tracks 92-95 form a track structure that allows the print head to reciprocate toward and away from the platen 69.

Ball track 95 is installed so that it can move relative to ball track 93. The compression spring 95' forces the pole track 95 towards the ball track 93, causing the ball track 93 to
Correct the gap between and 95. The device 50' is known as a two-line machine.

Two series L of printing bands 98 and 99 that can be selected and set,
and L2. Band 98 of series L can be selectively set by manual operation of knob 100, and band 99 of series L2 can be selectively set by manual operation of knob 101. /
The tabs 100 and 101 are connected to the opening 5 of the cover section 53.
It protrudes through 3'. A die roll 64a with a groove 64b through which the teeth 64' of the feed wheel 64 pass is rotatably mounted on the arm 64c.

The arm 64c is installed on the post 73. Arm 64c has an integral side tab 64g extending through slot 64f of one subframe 55. tension spring 64

and 43S to create perforations in the support web 32. Ink mechanism 102 includes an arm 103 that is pivotably mounted on a pivot 104 that is fixed to subframe 55 .

A retainer 105 holds arm 103 in pivot 104. The arm 103 supports a laterally extending small diameter pin 106 on which an ink roll 107 is installed. Pin 106 extends through an arcuate slot 108 in subframe 55. The tension spring 109 has one end connected to the arm 103.
One end of the side tab supported on the pin 111 acts on the pin 111, the other end of which is fixed to the print head 63. The position of the tube 110 and pin 111 is such that there is no substantial stretch or expansion in the spring 109 as the print head 63 moves from the solid line position to the dotted line (print) position shown by the dotted line 63' during the printing stroke. selected. Similarly, as the print head 63 moves between these positions on the return stroke, the spring 109
There is no substantial stretching or expansion. The position of pivot 104 pushes ink roll 107 from the solid line position to the dotted line position indicated by dotted line 107' during the printing process. During the return stroke of print head 63, ink roll 107 returns to the position shown by the solid line. Additionally, the force of spring 109 forces ball trajectory 92 toward ball trajectory 94 to compensate for the gap. The composite label web in roll form has a circular cylindrical core 112 of pole paper or other suitable material.

Boss 113, made of plastic or other suitable material, has three flexible, resilient sections 114 to which the core can be snapped onto and to facilitate removal of spent roll core 112. There is. Boss 113 is rotatably mounted on post 75 and clip 11
3'. Referring to FIGS. 5 and 6, there are generally V-shaped transverse grooves 115 equally spaced around the periphery of the feed wheel 64.

These grooves 115 greatly reduce the contact area that the support web 32 makes with the feed wheel 64. This minimizes the orientation at which the viscous rubber on the support web 32 is transferred to the feed wheel 64. The viscous rubber on the feed wheel 64 also causes problems in the feeding of the composite web 30. The land 116 on the outer periphery of the feed wheel 64 is about one-fifth of the pitch distance d, so the groove 115 reduces the contact area by 80% compared to a feed wheel with a continuous, smooth periphery.
To load apparatus 501, cover section 53 is removed and composite label web supply is applied.

The free end of the composite web 32 partially wraps under the roller 71 , passes over the platen 69 , around the stripper 7 0 , partially wraps under the platen 69 , under the roller 71 , and wraps around the roller 72 . It goes around part of the way, goes around the top of the feed wheel 64, goes over the peeling plate 76, and passes over the guide 77. When actuator 81 is released, brake roll 117 contacts the end of printhead 63 and is activated to prevent web 30 from ejecting while applying label 36.
Roll 117 presses web 30 against plate 118. Die roll 63 and its arm 64 can be moved to the position shown in FIG. 3 and cover section 53 snapped into place. When it is desired to print and apply a label 36, a firm squeeze on actuator 81 initiates the print and feed cycle, causing gear 82 to drive gear 66 and lever 67.

Pivoting of the lever 67 drives the print head into a position for cooperation with the platen to print data on the label 36. When the actuator 81 is released, the pawl 83 drives the feed wheel 64 so that the just printed label 36 is sent to the labeling position relative to the applicator 68, while in this position the trailing edge of the label 36 is It is still attached to the support web 32. Also,
The next consecutive label 36 is placed correctly on the platen 69 to be printed during the next printing cycle. 7th
In the illustrated embodiment, parts that are functionally equivalent to those shown in the embodiments of FIGS. 1 and 3-6 are given the same reference numerals. Referring to FIG. 7, actuator 81
supports the pivot 130. A link 131 is pivotally attached to a pivot 1301. A pivot 130 supported by a link 131 connects the link 131 and the bar 133. The lever 133 is rotatably installed on the post 74. The lever 133 has
A pawl 134 is provided which has the same function as pawl 83 in FIG. A pivot 135 is provided on the pin coupler 86 that extends through a circular hole 136 in the lever 133 and is secured to the print head 63. Instead of having the track structure of the embodiment of FIGS. 1 and 3-6, the subframe 55 of the embodiment of FIG. 7 has a track structure with elongated slots 137. , Koro 13
The pin 138 has a pin 9 installed thereon. Roller 139 is received in slot 137. When the lever 133 moves, the pin 135 draws a slight arc, so the print head 6
The right edge of 3 also draws a slight arc. The left end of print head 63 essentially undergoes reciprocating motion as roller I39 moves in a straight line. When printhead 63 is in the printing position, pivot 135 is in the position shown by dotted line 135', in which printhead 63 is perpendicular to platen 69. When actuator 81 is released, the spring assembly of FIG. 1 causes actuator 81 to pivot counterclockwise, thereby driving lever 133 clockwise to move print head 63 as shown in FIG. Return to position, and at the same time press claw 13
4 drives the feed wheel to advance the composite web 30 a distance equal to the length of the label 36. In the embodiment of FIG. 7, gear 82 has been removed from actuator 81. The apparatus of FIGS. 1, 3-6, and 7 is constructed primarily of molded plastic material. subframe 55
is preferably made of steel. Actuator 81, gear 66 and bar 67, ratchet and feed wheels 65 and 64, most of printhead 63, sections 52, 53, 64
, post 113, and tracks 94, 95 are made of a suitable molded plastic material. Referring to FIG. 7, link 13
The first bar 133 is also made of plastic material. In fact, in some cases, a small amount of viscous rubber pressure-sensitive deposit remains on the support web 32 after the label is removed.

In this case, when the support web comes into contact with the feed wheel 64, this viscous rubber material may be transferred to the feed wheel, impeding efficient operation during continued use of the device.
The feed wheel 64 is treated with a non-stick or releasable coating 116' sufficient to substantially prevent transfer of the viscous rubber or pressure sensitive adhesive present on the support web 32 to the feed wheel. There is a web contacting surface 116.

The web contacting surface of the feed wheel is sealed with a pressure sensitive tape (e.g. milk) after the pressure sensitive tape is pressed against the feed wheel under a pressure of 7.5 gw/(1 y.s.i.) for 2 to 5 seconds. It is preferred that the transparent tape 5910) be easily removed. Metal, or polyacetyl resin, polj carbonate resin,
A particularly preferred method of increasing the separation properties of feed wheels made of phenyl oxide, nylon, acrylonitrile butadiene styrene resins, unsaturated polyester molded resins, and other organic polymeric plastic materials is to add to the supporting web contact surface of the feed wheel. The idea is to apply a tacky continuous coating of a resinous coating composition that has a lower surface energy than the basic polymeric material of which the car is made.

Preferred coating compositions include compositions based on materials such as green cured all-silicone resins used in aircraft manufacturing and protective overcoat retention, and for making separation papers for pressure sensitive adhesive compositions. Solbend-based paper curing (soli) based on silicone polymers used in
ventbased papercmable) coating compositions. The coating must have sufficient adhesion to the feed wheel to avoid flaking during use, so the surface to be coated should be etched or otherwise slightly roughened before the coating is applied and cured. It is desirable to do so. This preferred method involves incorporating a lubricant into the feed wheel while it is being molded so that the feed wheel surfaces that contact the web provide sufficient material treatment separation properties to prevent viscous rubber build-up. and U.S. Pat. No. 3,698,745
It can also be distinguished from the method of applying a liquid lubricant to the feed wheel for this purpose according to No.

Although these other methods are also advantageous, the preferred method described above is more effective over long periods of time. Referring to FIGS. 8 and 10 through 36, a label printing and applicator, generally designated 150, is illustrated.

Apparatus 150 has a frame, indicated generally at 151, which includes a housing section 152.
, 153, 154 and a subframe consisting of a single rigid metal frame plate 155. The housing is essentially closed. Frame 151 has a handle, generally indicated at 159, consisting of a portion of handle portion 160 and a portion of frame portion 154. The housing section 154 has a screw 161 that is secured in a threaded hole 162.

3, and the protrusion 164 of section 153 is located in front of wall 1
It extends after 65. Section 153 is connected to section 152 with a snap-fit connector that includes a flexible, resilient member 166, typically snap-type, that fits into a raised bulge 1167 below section 152.
Section 153 is also provided with mounting bolts 168 that are secured in corresponding grooves 169 in section 152. The frame plate 155 includes a print head 1
70, feed wheel 171, gear or gear unit 172, applicator 173 shown in the form of a roll, platen 174, peeler 175 (installation pin 176 and a plurality of rollers 177, installation posts 178, 179, 180, 181) , and a support 236 are installed.

Frame plate 155 has two precisely spaced square holes 182 for receiving mating square mounting pins or undercut bolts 183. The holes 182 extend at right angles to each other, and the two opposing sides of each plunger bolt contact the corresponding long sides of the corresponding rectangular hole 182. Pins 183 cooperate with corresponding holes 182 to accurately position frame plate 155 relative to housing section 152. Although only one is shown in detail in FIG. 31, there are three equivalent mounting connections that secure the frame plate 155 to the housing section 152. Frame plate 155 has three large holes or cutouts 184. Housing section 152 has a pin or stud 185 extending through cutout 184 . Referring to FIG. 31, a retainer 186 in the form of a grip ring grips the stud 185. Shield bolt 18
A compression spring 187 fastened around 5 is in contact with frame plate 155 and retainer 186. Over time and with continuous use of the equipment, the coffin bolt becomes bidirectional in length.
Spring 187 ensures that plate 185 is always
52 to ensure a secure hold. Since the diameter of the dowel bolt 185 is significantly smaller than the cutout 184, the frame plate 1 relative to the housing section 152 is
The position of 55 is held by pins 183 in respective slots 182. The frame plate 155 has a pair of elongated notches or slots 188 with closed ends and a pair of opposed elongated notches or slots 189 with open ends.

Slots 188 and 189 have larger respective notches 190
I have good luck with and 191. Opposing pole orbit 1
92 and 193 are received in respective notches 190 and 191. Printhead 170 consists of a printhead frame 194 having a pair of opposing ball tracks 195 and 196. A ball bearing row 197 is inserted into a pair of ball bearing tracks 192 and 195;
Ball bearing row 198 is encased in paired ball bearing tracks 193 and 196. Ball tracks 192 and 193 are generally channel-type structures. When ball tracks 192 and 193 are in the position shown in FIGS. 10 and 11, ball tracks 192 and 193 are received in frame plate 155. A threaded fastener 199 extends through the notch 188 and connects the hole 1 of the ball track 192.

extends through the notch 189 and is threaded into the hole 200' of the ball track 193. The print head 170 has two series of printing bands (as shown in FIG. 31 of U.S. Pat. No. 36,745).
0 can print two series of data. Printed band 2
It is important to the print quality that the print head 170 move relative to the platen 174 so that the 01 characters uniformly contact the label 207 on the platen. If the printhead 170 is incorrectly aligned with the platen 174, some of the selected characters will be printed and others will not be printed at all or only slightly. Because the notches 188 and 189 are larger than the diameter of the fasteners 199 and 200 they pass through, ball tracks 192 and 193 can be placed in the correct position during device manufacture, thereby allowing the print head 170 to fit into the platen. 174 to maintain minimum clearance between the pole track and the corresponding ball bearing row. Print head frame 194
and ball tracks 195 and 196 integrally molded therewith,
Ball tracks 192 and 193 as well are made of plastic material. The balls of ball rows 197 and 198 are made of a hard material, such as steel, as shown in FIGS. 12 and 24 of U.S. Pat. No. 3,698,745. As shown schematically in FIGS. 21-23, the typeface 202 extends parallel to the platen 174. Since the ball trajectories 192 through 195 are all straight, the print head 170 is forced to move in a straight line. Therefore,
For good printing, print head 170 is connected to platen 1.
It must be moved perpendicular to 74. Therefore, to ensure accurate alignment of the printhead 170 and platen 174, a means is provided by which the movement of the printhead into the printing position of the composite web onto the label can be adjusted during or even subsequently during manufacturing. It is provided. Device 150 utilizes composite web 203.

The gear portion 227 meshes with the gear portion 229 of the gear 172. Gear portion 229 has one large tooth 230 that meshes with a tooth adjacent to gap 228 . Teeth 230'
Since it only mates with the link port 228, the actuator 222 can be assembled in the correct relative position with respect to the gear 172. Gear 172 has a gear portion 231 that meshes with a gear portion or rack 232 integrally formed on printhead frame 194 . The gear portion 231 has a cutout 233 formed by removing a tooth, and the gear portion 232 has a cutout 233 that is received in the cutout 233 to ensure that the print head 170 is only assembled in the correct relative position with respect to the gear 172. There are two large teeth 234. Assuming that the handle 159 is grasped by the user's hand, the user's fingers can manipulate the actuator to pivot the actuator 222 clockwise against the force of the spring 226 of the spring device 225. (FIGS. 8 and 10), which causes gear 172 to rotate counterclockwise L and print head 170 to move toward platen 174.
The label 207 is driven to a printing position that cooperates with the label 207 in an overlapping positional relationship. When actuator 222 is released, spring 226
similarly returns actuator 222 gear 172, printhead 170, and other parts described below to their initial positions. Sections 152 and 154 have stops 151'. The drive shaft 235 is molded integrally with the gear 172.

A support 236 in the form of a tube or tubular bearing is connected to the first
As best shown in FIG. 8, it is suitably secured in holes 237 in frame plate 155. As will be described in more detail below, feed wheel 171 has a plurality of laterally spaced pairs of teeth 171' that engage support web 245. Teeth 171', shown exaggerated in FIG. 21, extend forward and grip the feed edge of web 205. The feed wheel 171 includes a rim 238 to which teeth 171' are integrally connected. The rim 238 has an annular outer periphery with a wep-engaging section having a pead 238' and a central space or gap in which an annular section 238' is smaller in diameter than the section 238. As shown in FIG. 36, section 238' includes land 116a.
, which consists of fairly sharp peaks to provide essentially a line contact between wep 205 and land 116a. The gaps in the form of grooves 115a between lands 116a and sections 238'' reduce the contact area that would otherwise consist of the surface area of feed wheel 171 to a very small percentage of the circumferential area, i.e. 50%. or less. Preferably, it is reduced to 10% or less as shown in the figure. Sticky matter, viscous rubber, etc. that adhere to the feed dog 177 are collected in the gap 115a, and thereby the feed wheel 171 defined by the land 116a The outer diameter of the feed wheel 17 does not increase.
1 has the disadvantage of increasing the length of the web being sent. For example, the depth of gap 1 15a is approximately 0.63
On the side (0.025 inch), each section 238' has 190 lands 116a. Land 116a
Although it is sharp, it does not cut the web 205. Feed occurs as teeth 171' engage the web.
The feed wheel is made of plastic material, which has an inherently low coefficient of friction, at least on its outer circumference. In addition, the outer peripheral surface of the feed wheel 171 may be overcoated with a liquid or permanent coating material to prevent the build-up of adhesives, viscous rubber, etc., and to mix a suitable lubricant into the plastic material from which the feed wheel 171 is molded. is preferable.
An annular wall 239 connects the rim 238 and the boss portion 240. Boss portion 240' is large bore portion 242
There is a bore portion 241 that is immersed in the body. The bore portion 242 is provided with a plurality of grooves extending in the citron direction and a protrusion consisting of a ridge or vertical groove 244. A rolling contact one-way clutch 243 is received in bore portion 242 . The initial inner diameter of the bore portion 242 is defined by the crest of the protrusion. That is, the peak 244 is smaller than the outer diameter of the clutch 243. By forcing the clutch 243 into the bore portion 242,
A clutch 243 is assembled into the feed wheel 171, and the clutch 243
44 holds the clutch 243 in the position shown in FIG. 18 with a slight frictional force. Clutch 243 has a plurality of rollers 245 in contact with an outer circular cylindrical surface 246 of support 236. The one-way clutch 243 acts as a bearing to allow clockwise rotation of the feed wheel, but prevents counterclockwise movement, as shown in FIGS. 8 and 17. For example, specific examples of clutches useful in the present invention include
710 Torrington made by Torrington, listed in the 1969 catalog RC-6, catalog number RC.
There is something called the -081208 low-hoo clutch. A portion of the clutch 243 is shown in FIGS. 19 and 20.
As shown in the figure.

In the position shown in FIG. 19, the rollers 245 are in wedging contact with their respective mating surfaces 247, so that the clutch 243 prevents the feed wheel 171 from turning counterclockwise, while the second In the figure, feed wheel 171 is shown rotating in the direction of arrow A, with rollers 245 on surfaces 247 and 2.
It is not fixed between 46 and 46. Clutch 243 is spring-loaded, with a spring shown schematically at 248 constantly pressing rollers 245 against both surfaces 246 and 247. This causes backlash in clutch 243 to be negligible and when using a pawl such as pawl 248. In comparison, backlash is considerably reduced. The feed wheel 171 has a rim 238 and a wall 2.
39, including a web 249 to which a boss 240 is connected. A plurality of grooves 250 arranged in an annular manner as a first clutch member (in this example, a pawl clutch member) according to the present invention are provided on the inner periphery of the rims 238 and 238 on one side of the wall 239.
There is a mountain 251. Grooves 250 and ridges 251 extend in the axial direction. A ratchet wheel 252 serving as a driving wheel has a plurality of pawl teeth 253. Teeth 253 are integrally formed on one side of wall 254. The annular wall or flange 255 with a plurality of equally spaced gates 256 has a plurality of grooves 257 and peaks 258 as a second clutch member (pawl clutch section). Groove 250, mountain 251 and groove 25
7 and the mountain 258 have the same pitch, are spaced from each other, constitute a clutch (pawl clutch), and are connected to the feed wheel 171 and the ratchet wheel 252 so as to cooperate with each other. The ratchet wheel 252 also has an annular boss 2 with an internal bore 260.
It has 59. The support 2 is moved inside the bore 260 to a position where the end of the boss 259 is in contact with one end of the clutch 243.
36 is extended. At this position, the peak 25 of the ratchet wheel 252

are received in corresponding grooves 250 and ridges 251 of. Moving the ratchet wheel from its assembled position to the position shown in FIG. 18 selectively changes the position of ratchet wheel 252 relative to feed wheel 171. Such changes may cause the label 2 to change in the printing area between the printhead 170 and the platen 174.
07 to a position where the web 205 and the preceding label 207 are advanced relative to the peeler 175. The mechanism by which this is accomplished is described in U.S. Pat. No. 37,830.
It is partially the same as that described in No. 83. In cooperation with corresponding ridges 258 and grooves 257, grooves 250 and ridges 251 key together feed wheel 171 and ratchet wheel 252 to prevent relative rotation. Furthermore, the feed wheel 171 and the ratchet wheel 252 can only rotate in one direction due to the action of the clutch 243. Drive shaft 235 is rotatably mounted within circular cylindrical bore 261 of support 236 .

The drive shaft 235 is received in a boss 263 forming a cleft in the pawl structure, generally designated 264. Pawl structure 264 includes a pawl 265 that cooperates with tooth 253 at one time, as seen, for example, in FIG. Like gear 172, feed wheel 171, and rattle wheel 252, pawl structure 264 is constructed from molded plastic material. The split boss 263 is connected to the flat portion 26 of the shaft 235.

In FIG. 23, spring 275 is exerting a spring force along centerline 279. In FIG. Print head 17 is provided with a pair of spaced apart contacts 280 and 281. In the retracted position of print head 170 shown in FIG. 23, arm 272 contacts contact portion 280;
Brake shoe 274 is in contact with composite web 203 upstream of platen 174. When the actuator 222 is operated, the print head 17 is driven from the retracted position shown in FIG. 23 to the extended position shown in FIG. 22, thereby pivoting the brake section 271 to the position shown in FIG. 22, thus moving the brake shoe 274 out of braking with the composite web 203. In the position shown in FIG. 22, spring 275 exerts a force along centerline 282 on the other side of the axis of shield bolt 273'. Arm 272 and brake member 271 remain in the position shown in FIG. 22 until the print head moves away from platen 174 and the contact portion 280 is retracted enough to contact arm 272. Contact portion 280 is arm 2

When the shaft 291 is moved to the position shown in FIGS. 22 and 23, the arm 286 moves clockwise, thereby bringing the brake arm 283 into its effective position. Referring to FIG. 23, due to the inclination of the brake member 271 and the position of the brake shoe 274 relative to the brake shoe 284, the brake 274
The seventh factor is self-energizing. Therefore, when the label 207 is pasted, the peeler 1
The pulling force that the label was exerting on web 203 upstream of 75 causes brake 270 to exert an even greater braking force on web 203. Axis 291 carries a roll, generally designated 293, consisting of roll member 294 on one side of slider 288 and roll member 295 on the opposite side of the slider.

Further, the shaft 291 is connected to the pin 298 (eighth, first
It passes through an elongated arcuate slot 296 in an arm 297 which is pivotally connected to the arm 297 (Figs. 7 and 21). Washer 299 (Figure 8)
is arranged between the roll member 294 and the arm 297, and a retractable guide 300 is installed on the shaft 291 between the roll member 295 and a retainer 301 fixed to the tip of the shaft 291. Guide section 312 includes an integral pin 300 received in an elongated slot 300'' of guide 300.
′. In the position shown in FIG. 10, in which the guide 300 is in the solid retracted position, the guide 30 is out of guiding relationship with respect to the sides of the composite web 203. At the position indicated by dotted line 300PL in FIG. 10, the guide is in its effective guiding position. The shaft 291 is the frame plate 1
It is fixed to an arm 302 (FIGS. 21 to 23) that is rotatably installed on a bolt 303 supported by a bolt 55.

The tension spring 304 has one end connected to a tab 305 integrally formed on the arm 302 and the other end connected to a pin 306 fixed to the frame plate 155. In the position shown in FIG. 22, the roll 293 is in cooperation with the feed wheel 171;

Spring 304 exerts a force along centerline 309 on the mating side of shaft 308 to hold arm 302 and roll 293 in the illustrated position. Referring to FIG. 10, the user can remove the slider 288 by exerting a force on the left side of the protrusion 288'.
It will be obvious that the can be moved to the position shown. Roll 293, guide 300, arm 302 supported thereon, associated arm 286, and brake member 283 are moved to the position shown in FIG.
3. Not only are guides 300 and brakes 270 inactive, but springs 304 (FIG. 21) hold the components in position for easy loading of device 150. As can be seen in FIG. 10, shaft 291 is at one end of slot 296 in arm 297. Assuming that the label feeder is threaded onto the device, the first movement of actuator 222 causes arm 297 acting on shaft 291 to pivot arm 302 counterclockwise (FIG. 10); Accordingly, roll 293 is returned to cooperation with support web 203 and feed wheel 171, guide 300 is moved into guiding relationship with the side green of web 203, and brake section 283 is moved to the effective position shown in FIG. will be moved to Subsequent operation of the actuator causes arm 297 to move relative to axis 291 but due to slot 296 arm 297
has no effect on axis 291. Slider 288 and components operatively associated therewith can also be moved from the position shown in FIGS. 10 and 21 to FIG. 23 by pushing projection 288' to the right, as shown in FIG. It can also be configured so that it can be returned to the indicated layer. The composite web 203 comes into contact with it through an elastic device 310 in the form of a bent leaf spring from where it is pulled out of the roll.

As the feed wheel 171 advances the composite web 203, the elastic device 31 flexes and gradually returns to the device 31 as excess web 203 emerges from the supply roll after the brake 270 is applied. The track structure, generally designated 311, includes guide track sections 312, 313,
314 included. Track section 312 is connected to platen 174
has a pronged end 315 received at an end 312 of an extension 318 of the . A post 179 is provided on the track portion 312.
There is a short tubular portion 319 inserted into. Thus, track section 312 is held securely in place relative to frame plate 155 by end 215 and post 179. After passing through contact with the elastic device 310, the composite web 203 moves onto the printhead 1 over the track section 312.

Track section 314 has a curved retaining bracket 337 extending partially around flange 333 and a pair of spaced offset flanges 338 and 339 that align with the outside of channel feature 335. Tubular portion 330' secures one end of track section 314 to the frame plate, and flanges 336, 338, 339 connect track sections 313 and 314. Tubular section 319 is connected to tubular section 330
and 330'. Track structure 311 also includes a stripper 340 that engages smooth annular outer surface 171a of feed wheel 171.
The stripper 34 is provided with a pair of offset flanges 341 and 342 that fit into grooves 343 and 344 in track section 313, respectively. Post 179 is longer than the combined length of tubular sections 319, 330, 330', thus allowing projection 345 integrally formed on stripper 340 to fit snugly into one end of tubular section 331. As best shown in FIG. 26, an end 246 of elastic device 31 is provided with a pair of holes 347.

As best shown in FIGS. 24 and 25, housing section 153 is provided with a lock generally designated 357.

Lock 357 includes a slider member 358 that is inserted into an elongated pocket 359 in housing section 153. The slider 358 has a manual protrusion 360 for moving the slider 357 against the force of the compression spring 361.
It is included. Spring 361 is pushing against the end of flange 362 and slot 363. Slider 358 includes a pair of normally parallel spaced apart steerable, resilient arms 364 with corresponding protrusions 365 and tapered surfaces 366.
It is included. When slider 368 is assembled onto housing section 153, slider 368 is manually inserted into slot 36.
Pushed into 3. This causes the arm 364 to generate elasticity and tend to return once its protrusion 365 is pushed inside the housing section, as shown in FIG. A block 367 placed between and spaced apart from the arms 364 has a hole 368 for receiving the other end portion of the spring 361. In the assembled state, the spring 361 acts on the block 367 to push the slot 3
