Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic machine for applying one or more labels to articles being sequentially fed along a predetermined path.

In particular, the present invention relates to an improved labeling machine advantageous for the application of pressure-sensitive labels supported on a continuous backing web (SL-IJ tube) and fed to the machine, but in web-like form. It can be similarly applied to engraving other types of label application that are supplied or supplied from a hopper.

One of the objects of the invention is that when the strip is fed towards a means for stripping each label from the label strip;
It operates only on each label supported on the strip, and is applied to blank areas of the label strip, or areas that normally support a label but for some reason no label is supported there. An object of the present invention is to provide an improved labeling machine having means for disabling the labeling machine.

In particular, the main object of the present invention is to interrupt the successive labels on the strip despite the existence of areas in the label strip that normally support labels but do not support labels for some reason. The objective is to provide a labeling device that can be applied without serial numbering.

Another object of the invention is to provide an improved labeling machine comprising means for controlling the advancement of said label strip towards label separating means and detection means for controlling said control means. be.

The detection means initiates the advancement of the label strip towards the label separating means each time the article to be labeled is moved towards the labeling location and each label piece on the strip is in a predetermined position. stopping the strip from advancing towards the label separation means each time it passes, and each time a label piece in a label bearing area on the strip upstream of the end label piece is detected by the detection means; Although the strip stops advancing, if no label piece is present in the area, the I-IJ tab does not stop moving forward.

Other objects of the present invention as well as novel features of the present invention will become apparent from the following description based on the accompanying drawings.

11 in the drawings sequentially transfers articles 12 to which labels are to be attached to an operating mechanism as they move through the machine;
There is a conveyor for passing therethrough, which has a conventional structure as used in general labeling machines.

These actuation mechanisms may include means for accurately separating articles on conveyor 11 from one another.

These articles are then correctly aligned one after the other with the label applicator 16 at the labeling location 17.

Labels to be applied to articles are supplied from a label distributor 20 to a label applicator 16 at a label pick-up location 60.

The label applied to the article at the labeling location 17 is usually fully secured to the article at the next pressurized location.

While the article 12 moves to and passes through the labeling location 17, the lower surface of the pressure belt running on the conveyor 11 presses the upper surface of the label.

Thus, through this machine, these label sections always touch the running underside of the belt and the conveyor 1 while it is being transferred.
1.

The above-mentioned labeling station is equipped with a labeling unit for applying one label piece to each article.

This unit includes an intermittently rotating multi-station coolet 57, each station of which has an articulated vacuum labeling device 16 as shown in FIG. is the provision.

During the intermittent rotational movement of this turret, the applicator 16 sequentially stops at a label pick-up station 60 and sequentially picks up the labels 61 supplied thereto and transports these labels to a label applicator 17 where they are sequentially applied to the articles. Transport.

Device 2 for supplying pressure-sensitive labels 61 to the pick-up location 60
0 may be a commercially available pressure sensitive distributor such as those currently manufactured by Avery Products, Compact, and Denison.

The versatility of the machine of the present invention provides for pressure-sensitive labels that are fully or partially peeled from the backing web supporting the label and ejected from the dispenser at various angles, including vertical and horizontal. It can be seen from the fact that commercially available distributors such as those described above can be easily integrated with the machine of the present invention.

Therefore, the attached Figure 1 7. As shown in FIGS. 3-3, a typical commercially available dispenser is illustrated as including a housing 65 containing the necessary mechanisms to operate it.

The housing 65 is a backing strip on which a pressure-sensitive label is supported; a driven roll 66 that pulls out the IJ tab 67 from the supply roll 68; a label peeling plate 69; a backing strip 67; Take it up and reel 7
1 is also supported outside this housing.

According to the present invention, the housing 65 includes a table plate 74.
A bracket 72 is provided for adjustably mounting the distributor on an upright post 73 supported by a bracket 72.

The bracket 72 is also provided with a horizontal fixing rod 15 that rotatably supports the supply reel 68.

In operation of the dispenser shown in FIGS. 1-3, the backing strip 67 on which the label 61 is supported is withdrawn from the supply reel 68 and removed from the sharp edge provided at the lower end of the peeling plate 69. It is designed to progress around the area.

The labels 61 are sequentially peeled from the backing strips as the backing strips are successively flipped over the sharp edges of the peel board.

As each label 61 begins to peel free from the retrograde backing or carrier strip 67 at the bottom of the peel plate 69, the labels 61
It will be clearer from FIG. 3 that the suction backing plate 79 is directed vertically and downwardly across the vertically aligned outer surface γ8 of the suction backing plate 79.

Shortly after the label is totally free from the carrier paper strip, the advancing end of the label is in a position to pick up the label, as will be seen later, and the center line of the container 16 and the center line of the label are exactly aligned. A stopper 8 installed on the plate material γ9 to properly align the label with the
Contact with 0,80.

The feed rate of the backing strip is set free in order to ensure that the label seats against the stop 80.80 despite the delaying effects exerted on the label by suction through the plate 79. The velocity is such that the labeled label is propelled forward across surface 78.

Once the stops 80, 80 arrest the label's forward movement, the label is immediately gripped and held in its aligned position by the suction applied through the plate 79.

The suction backing plate 79 forms one wall of a label holding device 82 which is suspended from the bottom of the housing 65.

The holding device 82 is assembled in the form of a housing such that a closed chamber 83 communicates with the interior of the housing 65 via an opening in the bottom thereof.

Inside the housing there is an opening 84 in the plate 79 (FIG. 3).
A suitable fan (not shown) is provided to create a low vacuum within the housing which is applied via the housing over the portion of the plate 79 to be covered with the label 61.

The vacuum thus created is sufficient to hold the label in alignment with surface 78 until the label is securely removed from surface 78.

It can be seen from FIGS. 1 to 3 that the plate 79 and thus the holding device 82 are provided with a groove-like opening 85 through which the applicator 16 passes in a stepwise movement.

During each rotation period of the coolet 57, one of the containers 16 is attached to the label bearing surface 86 and the label holder 82 in front of the container 16.
The label bearing surface 86 is placed in a resting position within the aperture 85 with the label bearing surface 78 of the label 61 aligned substantially coplanar with the label bearing surface 78 of the label holder. It comes into contact with the center part of the printing side of the paper.

The timing relationship of the machine is such that the applicator reaches this position after the label 61 has been released from the support sheet 67 onto the surface 78 of the label holder.

As can be seen in FIG. 2, the shafts of the two backing strip drive rolls 66, 70 of the distributor are each provided with sprocket wheels 87, 88, each connected by a chain 89.

Associated with this sprocket wheel 87 is an electric clutch-brake unit 90 which controls the rotational movement of the drive rolls 66,70 and thus the feeding of the carrier sheet 67.

This unit 90 includes electrical control and relay box 195 (fifth
1) and is excited by the photoelectric beam unit 91 shown in FIG.
Feeding of the sheet toward the label pickup location 60 is started.

This photoelectric beam unit 91 is located at a relative position with the conveyor 11, i.e. at least 3 ft. of the pitch between the articles 12.
Label pasting is installed upstream of location 17 by twice the distance.

Thus, if the article 12 blocks the beam of the photoelectric beam unit 91, the backing strip 61 of the pick-up location
supply will begin.

Because the photoelectric beam unit 91 is located in such a position, the feeding of the backing strip 67 is started whenever the article to be affixed with the frontmost label on this backing strip is on the conveyor. The application takes place immediately after the container passes the label holder 82.

The feeding of such a strip is carried out by a photoelectric beam unit 9.
Further controlled by 2.

The photoelectric beam unit 92 is installed within the distributor housing 65 as shown in FIG. 2 and is also electrically connected to the electrical control and relay box 195 (FIG. 5).
The electrical control and relay box controls the operation of the clutch and brake unit 90.

This beam unit 92 is connected to a backing strip 67 upstream of the leading edge label on such a strip.
are arranged in a well-known manner to transmit an electrical signal to the electrical control and relay box 195 when the trailing edge of the next label strip 61 on said backing strip passes through the beam of said unit. to the clutch and brake unit 90, thereby stopping the feeding of the backing strip to the pick-up station 60.

Once this action occurs, the leading edge label piece on the backing strip is forced into alignment on the label holder 82, thereby stopping its movement.

Application therefore occupies the next stop period of the machine when the container 16 is moved to the rest position, and the label 61 is placed on the label holder 82 in an aligned rest position.

While the machine is stopped, the center lines of the label 61 aligned with the applicator 16, the groove or opening 85, the backing plate 67 on the peeling plate 69, and the stops 80, 80 all substantially coincide. It can be understood from FIG. 3 that this happens.

With this arrangement, the label 61 is then aligned on the label holder 82 when a vacuum is applied to the applicator 16 and the applicator advances to the next stage of its own movement. At a position where the center line of the label and the center line of the label supporting surface of the container match, the label is firmly supported by the container.

Although in the illustrated example these centerlines are represented as a means of effecting the desired alignment, it is understood that any predetermined line on such elements may be selected as a means of achieving such alignment. It will be.

In accordance with well-known methods for depositing pressure-sensitive labels onto backing sheets, the labels are supported on the backing sheet so that all the labels are precisely positioned on the backing sheet in exact relation to each other. It is known in the art that

Thus, a predetermined longitudinal line on the conventional backing sheet on which the pressure sensitive label is provided can be selected as a reference line.

The backing strip is thus fed to the label removal location on the backing strip under the positive control of guide members such as guide members 64, 64 shown in FIGS. Labels whose predetermined lines, or center lines in the illustrated example, are in such alignment on the stops 80, 80 are released with their corresponding predetermined lines aligned.

The stops 80, 80 can overcome any inaccuracies that may occur during operation of the dispenser, such as during stripping and thrusting of the dispenser.

When the label 61 is moved across the surface 78 of the plate 79 on which the above-mentioned stop is installed, the label 61 moves across the surface 78 of the plate 79.
It will also be appreciated that the movement is retarded by the frictional and pneumatic resistance imparted by 8.

Since the rate of release of the label from the backing sheet is a function of these resistance conditions, the label is successively brought onto surface 78 under positive control of the vacuum until it comes into contact with the stop. , across the surface at a speed sufficient to provide accurate alignment on the stop without distortion.

Preventing such distortion is also aided by the vacuum.

When the movement of the label is stopped by the stop 80.80, the suction applied through the openings (i.e. ports) provided in the plate 79 grips the label and the application of this label is carried out by the device. 16 to hold the label in proper alignment to be picked up.

The suction force required for these purposes is between 2.54 and 3.5 mm in units of mercury.
08α or 1/2 to 1 pound per square inch.

Thus, a greater suction force is applied to the applicator 16 than the suction force exerted on the plate 79, and a gripping force greater than the suction force exerted on the label piece by the plate 79 is applied to the label.

For example, such an application would provide the vessel with a suction force of approximately 15 inches of mercury (approximately 2.54 crILX 15 ), or 7.5 pounds per square inch.

Thus, once the applicator 16 is advanced to the next stage of travel, the applicator can peel the label off the plate 79 without disturbing the aligned position of the label on the applicator.

As shown in FIGS. 1 and 2, the turret of the labeling unit has a vertical axis extending through it which is rotatably supported by a suitable bearing unit 96 mounted on the table plate 74. 95.

A cam plate 97 having a cam roller 98 that engages a cam groove of a cylindrical cam 99 is secured to the lower end of the ring 95 below the table plate 74 in a manner well known in the art.

Further, the cylindrical cam 99 is fixed to a horizontal shaft 100 rotatably supported by bearings 101, 101 provided at the lower end of the suspension bearing bracket supported by the table plate 74.

A sprocket wheel 102 is installed at one end of this shaft 100 and is connected by a chain to a sprocket wheel fixed to the main shaft of the machine.

A vertical shaft 95 above and in a spaced relationship with respect to the chiffle plate 74 is affixed with a label such that the six labels of the unit are suitable for rotatably supporting the vertical shaft 107 of the device 59. A turret plate 105 is secured which is supported in six vertically aligned bearing units 106 in spaced relationship.

A cam arm 108 is fixed to the lower end of each vertical shaft 107 and includes a cam roller 109 that engages a cam track 110 provided within the upper surface of a horizontal cam plate 111 mounted on the top of the table plate 74.

The cam trajectory 110 moves from the label pick-up location 60 to the label application location 17, and the label application location is such that the centerline of the label bearing the surface 86 of the container 16 is aligned on the label holder 82 at the label pick-up location 60. coincides with the center line of the label, and the label is applied at location 17 on the axis 9 of the turret.
Each label application is designed to sequentially rotate the device 59 while returning to the label pick-up station 60 so as to coincide with the centerline of the article in a radial vertical plane.

Each label applicator 59 is comprised of a substantially cylindrical body 112 slidably mounted on a shaft 107 and provided with an annular cam track 113 .
A cam roller 114 provided at the inner end of a pivotable lever arm 115 is mounted within 3, and a labeling device 16 is mounted at the outer end of the lever arm.

The arm 115 is installed to rotate around the axis of a pin 117 provided on a bracket device 116 fixed to the upper part of the shaft 107.

Thus, as the body 112 is slidably moved vertically on the shaft 107, the arm 115 is rotated about the axis of the bracket bin 117 by the cam track 113 and the cam roll 114, whereupon the application is moved forward or backward as shown by the dotted and solid lines in FIG.

The body 112 is normally attached by means of a vertically arranged compression spring 118 fixed at both ends to a column 119 of this body and a column 120 fixed to a collar 121 of the shaft 95, so that the application is not complete until the vessel is fully advanced. is biased towards the uppermost position.

The range of movement of the applicator 16 from the fully retracted position to the fully advanced position is determined by a cam roller 123 whose upper portion is fixed to the main body 112 and which engages the bottom cam edge 124 of the ring cam 125 at its lower end. It is controlled by a cam mechanism that includes a vertical arm 122.

The ring cam 125 is a pillar 127 installed on the cam plate 111.
It is supported in concentric relation to the turret plate 105 by an ear member 126 that is adjustably secured to the turret plate 105.

Each arm 122 is slidable within a guide flock 128 secured in projecting relation to the coolet plate.

Although the body 112 is thus slidable on the shaft 107, its rotational movement is restricted by the arm 122 and the guide block 128.

In operation of the machine, the cylindrical cam 99 is continuously rotated by the main shaft of the machine through the sprocket wheel 102 and the sprocket wheel engaging the shaft 100, and the turret plate 105 is rotated each cycle of such operation. In the middle, it is advanced one step by a cylindrical cam 99.

During this stepwise movement of the turret, the cam member 123 of the labeling device 59 is positioned at the pick-up location 60 shown in FIGS.
6 is provided on the ring cam 125 to vertically position the label bearing surface 86 of the label 61, and the cam roller 109 is positioned parallel to the printed side of the label 61 which is held in registration by the label holder 82. The label bearing surface 86 is positioned on the plate cam 111 to position it.

In this state of each component, the center line of the surface 86 of the container coincides with the center line of the bell 61, which is held by a weak suction force on the holder 82.

Prior to the next step of movement of the applicator 16, a suction force is applied within the applicator 16 that is greater than the suction force applied to the label by the retainer 82, so that the applicator holds the label in its alignment. hold firmly under.

Application is the next step in the application device 16, which peels the label from the retainer 82 and the cam plate 111 changes the relative angle of the retained label with respect to the radial plane to the axis of the coolet shaft 95. Therefore, the pasting is done on the axis 1 of the device.
07 and the ring cam 125 rotates the applicator 16 about the pivot 117 so that the label applicator on its axis 107 begins to change the position of the body 112 of the device 59.

Upon completion of this first stage of movement from said pick-up location 60, the label and affixing device is labeled 6 in FIG.
1' and the attachment is in the position indicated by vessel 16'.

This process continues so that at the end of the next phase of movement of the turret, the label and applicator are in the positions indicated in FIG. 1 by label 61'' and applicator 16'', respectively.

Since by this time the label has already been transferred to the next position, this label is attached to the article 12 on the conveyor 11.
It is almost parallel to the direction of movement of.

During the next stage of the turret and application, when the vessel reaches the location indicated by a perpendicular plane 130 that contains its own centerline and is radial to the axis of the shaft 107, the vessel 16 is attached to its label. The bearing surface 86 is rotated forward to a position for applying the label to the article 12' represented by the dotted contoured edge of the container 16.

At this point, article 12' has advanced from its solid line position to a position where its centerline is also contained within vertical plane 130;
It is then understood that the supported label is parallel to the path of travel of the article.

The surface 86 of the vessel 16 is attached so that this is its centerline and axis 1.
This parallelism is maintained until approximately the location indicated by the vertical plane 132 is reached through the 07 axis.

During this period, the applicator surface 86 undergoes a movement parallel and equal in speed to the movement of the articles 12' on the conveyor 11.

While surface 86 is moving the distance between surfaces 130-132 parallel to part 12' and at a speed equal to article 12',
The ring cam 125 causes the applicator 16 to swing forward and backward for the purpose of applying the label to the article 12'.

This labeling operation takes place at the location indicated by the vertical plane 131.

At this point, the centerline of the article 12', the centerline of the applied label 61, and each centerline of the applied container surface 86 are contained within the plane 131, and the centerline of the applied label 61 is
It is understood that labeling is radial to both the device axis 107 and the turret axis 95.

During this final pulsating movement of the applicator 16, the vacuum applied to the applicator is released and a positive evacuation of air is allowed to flow through the applicator in order to ensure that the label is affixed to the article. .

During the return movement of the device to its pick-up location, the device 16 is retracted and
It is moved through the passageway 85 within the unit 82 and rotated until it is returned to a state ready to pick up the labels aligned on said unit as shown in FIGS. 1-3.

Apparatus for controlling the pneumatic conditions of the applicator 16 is shown in FIGS. 1-3.

As shown more clearly in FIG. 2, a portion of such a device is mounted on the upper end of a turret shaft 95, is fixed to said shaft, and is rotatable with six equally spaced valve openings 136. A flexible valve plate 135 is included.

Only one end of six flexible hoses 137 are connected to this valve plate material, and the other ends of the flexible hoses are connected to the container 16 with appropriate attachment.

A stationary valve plate 138 is mounted on the valve plate 135, and both plates are separated by a sliding ring made of any suitable sliding material, such as Lyuron or Teflon.

Plate 138 is provided with a solid bearing alignment opening for receiving the upper end of turret shaft 95 and includes three openings between a pick opening, a transfer opening, and a blowout opening. be.

These three openings have their pick-up opening located at label pick-up location 60, their blow-off opening located at label-apply location 17, and their transfer opening located between the pick-up and blow-off openings. A label is placed on the stationary plate 138 such that the label is carried by the labeling device along its path.

The transfer opening provides a continuous suction force within the labeling device 16 during the time that the labeling device 16 moves from the label pick-up location 60 to the labeling location 17.

The three openings mentioned above are connected to an air supply source by appropriate valving, so that labeling can be carried out at the pick-up opening in the stationary plate 138 if the device 59 is positioned at the pick-up location 60 while the coolet is stopped. Through the labeling section of the device, a vacuum is applied to the vessel 16, thereby allowing the labeling vessel to pick up the label aligned with the label holder 82.

Through the next two stages of the coolet, labeling is accomplished by vacuum being applied to the device or finger 16 through the transfer opening as it advances.

During the time when the labeling device 16 is moving with the conveyor 11 at a constant speed, the vacuum application to the moving opening is discontinued and the labeling is carried by the device (fingers) 16. Air pressure is provided through the blow-off opening to blow off the label.

The article 12 thus labeled is then passed from the labeling station 17 to a pressure station for applying a final finishing pressure to the applied label.

For this purpose, suitable means may be employed such as pressure means as disclosed in US Pat. No. 3,522,134 (July 28, 1970) for applying labels.

Figures 4 and 5 provide a detailed description of the invention which ensures that each label is coded or collectively numbered even if no label is present on the carrier sheet fed to the distributor.

As previously explained, the photoelectric detection means 92 within the housing 65 is activated by the support backing strip or web 67 when the rear edge of the label 61 passing through the detector emits the light to excite the detector. This is to stop movement.

During such periods of suspension, the code or batch number printer 191
prints the desired code or batch number on subsequent labels 61'.

Now, as shown in FIGS. 4 and 5, the detection unit 92 (first detector) has just been excited by the label 61 for the purpose of stopping the feeding of the backing strip 67, and if 19 as the following label is provided.
Let us assume that the space represented by 0 is blank.

In this case, on the next movement of this web, there will be no label in space 190, so that detector 92 will continue to advance the web until the rear edge of the next adhered label 61'' excites detector 92.

Continuous advancement of the web past two stops will result in failure of labels 61' following labels 61' to be coded or numbered.

Therefore, if such a label is affixed to an item, there is no way to trace the item if its contents become a problem.

According to the invention, this possibility is achieved by electrically connecting the second photoelectric detection unit 194 (second detector) and the detector 92 (first detector) so that said detector 194 also The electrical control and relay box 1 is activated when the rear edge of the label 61' passes through this detector after the normal one-stop advancement of the web.
The solution is to send a signal to 95 to stop the web.

Therefore, the printer 191 prints a code or batch number on the label 61.
”.

A printer 191 of the type employed in labeling machines manufactured by, for example, New Chassis Machine Corporation of New Chassis, U.S.A., has a construction well known in the art. In such a suitable manner, the label applicator is connected to the main drive shaft of the machine, so that the printer is energized to print a label each time the bearing strip 67 stops.

The manner in which the above-mentioned control is implemented is an electrical control system in which the photoelectric detector 91 (third detector) for detecting the article and the photoelectric detectors 92, 194 for detecting the label are electrically connected. It is clear by considering FIG. 5, which shows relay box 195.

The mechanism inside the box 195 includes a printer 191 and an electric clutch 1.
96 and brake 197 are also electrically connected.

These clutches and brakes constitute a clutch-brake unit 90 shown in FIG.

Thus, a signal from either detector 92 or 194 will stop the web, apply the brakes, and energize printer 191.

That is, even if there is no label at the position detected by the first detector 92, if a label is detected by the second detector 194, the support strike IJ knob is stopped, the printer 191 is activated, This prevents the label code and batch number from being omitted from printing.

The feed of the web is excited by the articles 12 passing across the conveyor 11 and exciting the detectors 91.

A conventional drag pad 198 is provided in front of the bearing I-IJ knob 67 to prevent it from becoming loose as it passes over the detector 194.

A free loop 199 between the drag pad 198 and the pull roll 200 to advance the web from the supply roll 68.
It is also desirable to provide.

The preferred embodiments of the present invention have been described above with reference to the accompanying drawings.

Therefore, it will be obvious to those skilled in the art that the present invention can be modified in various ways without departing from the technical idea of the present invention or the scope described in the original claims.
