SECTION 1 OVERVIEW INTRODUCTION Featuring solid-state circuitry and an AC Synchronous Motor, the L60 is a high performance, low maintenance label applicator. The L60 applicator is designed to apply a pressure sensitive label to a product through the action of an air-cylinder-mounted, or blow-on, vacuum head. The labeling process can be automatic when interfaced with a conveyor, or semi-automatic with a table-based product fixture. When triggered, the L60 Tamp vacuum head extends

SECTION 2 SETUP AND OPERATION ASSEMBLING THE L60 Using a square, mount the Unwind Assembly to the back of the L60 using the 2 screws provided. The top screw is a ¼-20x1-1/2” socket head cap screw, the bottom screw is ¼-20x1-1/4”. Please note: Screws. Top one is longer. Fig 3 Maximum reliability is assured when the Compressed Air supplied to the L60 is Clean & Dry. Over time, moisture will take its toll on the Solenoid Valves and Air cylinder. Also it is not recommended to a

FUNCTION OF UNWIND ASSEMBLY The unwind is simple, but important to the operation of the L-60 machine. When the motor starts, the web and labels are pulled through the machine by the drive roller. The label stock pulls on the brake arm, releasing the brake, and allows the roll of labels to unwind. When the motor stops, the brake arm returns to the rest position. This movement tightens the brake band around the 3" diameter main unwind hub and the roll of labels stops unwinding. The L-6

WASTE REMOVAL 1. To remove waste web, turn off the machine, and remove the rewind spool clamp. Fig 5 2. Tear the web first. 3. While holding the rewind backing plate, turn the whole waste web in the opposite direction and pull. Page 10

MOUNTING THE L-60 The L-60 can be mounted from the bottom or the top. The most common method is bottom mount (see Fig 6). Fig 6 shows the L-60 mounted to the optional base plate with standoffs. Fig 7 shows the top of an L-60 ordered with standard mounting and can accept a coder. Fig 8 shows an L-60 Ordered for top mount. Six holes have been provided in the two lower tie bars. Any combination may be used. The hole pattern most used is 6-1/2" square, which is where the 4 legs are sho

THEORY OF OPERATION TAMP CYLINDER RETURN OPTIONS Dwell Timer (Standard on all L60 Tamp Applicators) “Dwell Time” is the time duration of the signal that opens the valve, which activates the air cylinder. This time duration can be adjusted with the three- turn dial located on the front panel of the machine. Turn the dial clockwise and the duration to Dwell timer Fig 9 increase the dwell time signal. After the label apply signal is given, the air cylinder extends and the time durat

LOWER “HALL EFFECT” SENSOR (OPTIONAL) Some L60 tamp label applicators are equipped with two sensors that are attached to the air cylinder. One is located at the top of the cylinder and the other is located below it. The upper sensor sends a signal to the machine so another label will be dispensed onto the vacuum head. The lower sensor can be adjusted to control or limit the stroke of the air cylinder that returns the vacuum head to the home position. The lower sensor is the only one t

“SMART HEAD” (OPTIONAL) The Smart Head is used if there is a variation in height of the product or the location of the product on the conveyor cannot be controlled. Simply put, the air cylinder is going to travel it makes contact with the product. A “smart head“ vacuum head is constructed so that the pad that holds the label compresses when the label is applied. When a sensor detects a specific amount of compression, it sends a signal to the machine telling the air cylinder to return

EXPLANATION OF LABEL TRANSFER As the label is being peeled, it should first contact the center of the bevel on the Vacuum Head. This will deflect the label slightly downward. The air from the Air Assist Tube will keep the label up against the face of the Vacuum Head. NOTE: The label is deflected downward so that after it is transferred to the head, it will be resting in a position below the peeler plate edge. This is done so the label will not contact the peeler plate edge, as it is

Air Assist Tube The Air Assist (Drawing L60-I-30D #26) is a tube with a series of holes through which air rushes assisting the transfer of the label to the Vacuum Tamp or Blow Head. The air will rush through the tube only when the motor is running and the label is being peeled and transferred. Air Assist tube Fig 15 It is our experience that as the roll of labels becomes smaller in diameter, some labels tend to curl after they are peeled from the backing web. The Air Assist tube

WEBBING THE L60 Fig 16 1. Turn off the Main Power switch (22) on the Front Panel 2. Loosen the black thumbscrew (19). 3. Slide off the removable label retainer (20). 4. Place a roll of labels on the Unwind Hub (01). 5. Loosen the Socket Head Cap Screw (02) on the Clamp of the Unwind Backing Disc (03) and position the roll of labels so the labels track centered on the Vacuum Head (06) when peeled off (See FRONT VIEW). (NOTE: For round or oval labels, it is important that the S

10. Pull the web under the Star Wheel and down between the first Idler Roll (09) and the Label Guide Support Plate (08), then forward over Idler Roll (10) and under Idler Roll (11). 11. NOTE: There are 2 Web guides located here also. Adjust them as above in Step 8. 12. Next, pull the web between the Peeler Plate (12) and the Web Drag (13). 13. Pull the web until approximately 18” extends from the peeler plate, Remove any labels that are on this part of the web. 14. Bring the web back

RUNNING THE L60 1. Turn the main switch ON (01). 2. Turn motor switch ON (02). 3. Connect air supply. CAUTION: This may bring the Tamp Head up abruptly. Keep fingers clear. 4. Cycle the machine several times (trigger the Product Switch (09)) and observe the label web tracking. Web tracking should settle to a consistent line. Once you have determined a consistent line has been achieved, set the web guides on each side of the web. NOTE: To ensure the label feeds properly onto the Va

LABEL SENSING STAR WHEEL The star wheel causes the applicator to stop dispensing a label. When the star wheel is down on a flat side, it will slide over the label until the lead edge of the next label contacts the point of the wheel causing the wheel to turn over. As it turns up on a point and back down, the star wheel arm activates a small micro-switch breaking the circuit, thus stopping the advance of the label web. If the star wheel arm fails to activate the switch as it turns over t
