PINNING METHOD AND APPARATUS

Abstract of the Disclosure There is disclosed a tag attaching method, particularly a method of pinning tags to merchandise and apparatus for carrying out the method. The illustrated apparatus includes a plunger and a cooperable anvil between which a tag and merchandise are positioned and through which a fastener specifically a pin is driven to attach the tag to the merchandise. While the pin is being driven through the tag and merchandise, a movable pin guiding and crimping member moves relative to the plunger, the tag and the pin. The pin is driven firstly through the tag, secondly through the merchandise, thirdly through the merchandise again, fourthly through the tag again, and fifthly through the tag again, and thereupon the movable pin guiding and pin crimping member is moved again to crimp the pin. A bottom tag in a stack is separated by feeding it toward the pinning zone in one machine cycle and the separated tag is positioned between the anvil and the plunger during the early part of the next machine cycle. The tag feeding device for separating the bottom tag and the tag feeding device for positioning the separated tag at the pinning zone move relative to each other during the pinning cycle. A
cycle of machine operation can only be initiated when manually operable actuators disposed on opposite sides of the anvil and plunger are both actuated.

Description

Docket M-326 Summary of the Invention The method of the invention utilizes an anvil and a cooperable plunger which are movable relative to each other. The anvil and the plunger are cooperable to hold a tag and merchandise in a bent orientation so that a pin can be driven through both the tag and the merchandise.
A movable member which is movable relative to the plunger and the anvil, is repeatedly moved during the time a pin is driven through the tag and the merchandise to assist in guiding and bending the pin firstly through the tag, secondly through the merchandise, thirdly again through the merchandise, fourthly again through the tag and fifthly again through the tag.
The movable member is also effective to crimp the pin which has been completely inserted or almost completely inserted through the tag and merchandise. The crimping operation bends the leading marginal end of the pin so that the point of the pin is inclined toward the underside of the tag and away from the merchandise. Thus, crimping is that action which relates to a final bending of the pin primarily to make it difficult to remove and reinsert through the tag and merchandise.
According to a specific embodiment of the method, merchandise is positioned at a pinning zone between the anvil and the plunger, a tag is fed along a path to the pinning zone while a movable pin guiding and crimping member is spaced from the path. The pin guiding and crimping method is now moved for the first time toward the plunger. Thereafter, the plunger is moved toward the anvil to hold the tag and the merchandise in a bent orientation at the pinning zone. Thereupon, a pin is ~ - 2 - ~

, " ~' ` ~ ' ' ' , ~ 5 Docket M-326 driven through both the tag and the merchandise once and thereafter the pin driving and crimping member is moved a second time away from the plunger to allow the pin to be driven through both the tag and the merchandi~e again. The S pin guiding and crimping member moves a third time toward the plunger while the pin is being driven to bend the pin toward the tag to enable the pin to be driven through the tag again.
When this has been accomplished, the pin guiding and crimping member is moved the fourth time away from the plunger. There-after, the pin guiding and crimping member is moved a fifth time toward the plunger but to a greater extent than during the first and third times while supporting a leading end portion of the pin to crimp the pin. There is also provided apparatus for carrying out the method. ~n improved apparatus relates primarily to the mechanism for controlling the oper-ation of the movable member which serves the dual function of guiding the pin and crimping the pin. According to a specific embodiment of the invention, a cam shaft drives an actuator which is coupled to the movable pin guiding and crimping member, to the pin driver and to the paper strip feeding mechanism. The actuator drives the movable member through an arrangement of cams which cause the movable member to undergo repeated movements as characterized above with respect to the method. Accordingly, a pin which is originally straight, is driven through both the tag and the merchandise and the bending of the pin and the subsequent crimping of the pin is under the control of the movable member.

The plate 420 has a ~ab 421 against which blunt end 422 of the needle 411 is seated. Two screws 423 passing through respective holes 424 in the plate 420 are received in threaded holes 425 in the member 396'. An end portion 426 of the plate 420 adjacent the slot 419 is bent outwardly.
A worn needle 411 can be readily removed as by grasping the exposed end portion with pliers and pulling the needle 411 out of the groove 419. A new needle having a sharp end can be inserted into the groove 419 using pliers which can be used to push the needle into the groove until end 422 ~ ,.
is seated against the tab 421. The other mounting members 397' and 398' and associated latch components are identical to those shown in FIGURE 45.
Referring now to FIGURE 46, the switches 344 and 345 include mechanically connected switches 430 and 431 and 432 ;~ and 433, respectively. When the switch 344 is closed, the switches 430 and 431 are closed, and vice versa. When the switch 345 is closed, the switches 432 and 433 are closed, and vice versa. The clutch solenoid 65 is connected to a normally closed switch 434. The switch 430 is connected to a lead 435 and the switch 434 is connected to a lead 436.
The switches 430 and 432, the clutch solenoid 65, and the switch 434 are connected in series. The seitches 431 and 433 are connected to the lead 435 and to a node 437'.

Docket M- 3 2 6 , 441 in parallel with each other are connected to a node 439 and to the lead 436. The switch 440 is controlled by Zl cam 437 secured to the cam shaft 67. When the cam ; sha~t 67 is in the home position the cam 437 holds the switch 440 open. The electric motor 51 is connected to the leads 435 and 436 through a switch 438a. The motor 51 operates whenever the switch 438a is closed. When one of the switches 344 or 345 is closed and the other one is open, neither the clutch coil nor the relay coil 438' can be energized. It is apparent that manual actuation of the actuator 342 or the actuator 343 without actuation of the other is ineffective. It is only when the switches 344 and 345 are ~' simtlltaneously in the closed position, that the clutch coil 65 is energized through the switches 430 and 432 and the normally closed switch 343. Energization of the clutch ,. . .
coil 65 will cause the clutch 64 to be engaged, thereby causing the cam shaft 67 to rotate. Rotation of the cam shaft 67 will cause the cam 437 to rotate, thereby closing the switch 440. When the switch 440 is closed and assuming ,: .
that at least one of the switch elements 431 and 433 is still in the closed condition, the relay 438 will be energized, thereby opening the switch 434 and closing the switch 441.
The switches 434 and 441 are part of the relay 438 and are mechanically coupled to the relay coil 438' as indicated by respective broken lines 442 and 443. Opening of the switch 434 causes the clutch solenoid to be deenergized thereby ` causing disengagement of the clutch at the end of one complete ;;: ..

If both of t:he actuators 342 and 343 are released, then both the switches 344 and 345 will be open and consequently the switches 431 and 433 fail to complete a circuit through the relay coil 438', thereby causing the switch 434 to close and the switch 441 to open. Accordingly, the clutch can only be operated again by actuating both actuators 342 and 343 so that the switches 344 and 345 are simultaneously in the closed condition. It is apparent that the switch 344 can be closed before the switch 345 is closed, or vice versa, but it is only when both the switches 344 and 345 are in the closed condition that the clutch solenoid 65 ;15 is operated and the clutch solenoid 65 cannot again be ; operated until after both the switches 344 and 345 are released.
With reference to an al~ernative embodiment shown in FIGURE 47, there are shown leads 444 and 445. The lead 445 is connected to a node 446 through a switch 447.
The electric motor 51 is connected to the node 446 and to a node 448 which is connected to the lead 444. Switches 449 and 450 and the clutch solenoid 65 are connected in series :~ with each other and in turn to respective nodes 446 and :"f 448. The switches 449 and 450 are positioned to be acutated by actuators 342 and 343 and are disposed in the same positions relative to the actuators 342 and 343 as are the switches 344 and 345 in the other embodiment.

the tag T from the stack S moves through an operational sequence which overlaps the operational sequence of the tag feeding device 181 which advances the tag T to the ~15 pinning zone. It is to be noted that the movement of the feed is completed relatively early in the machine cycle to position a tag T at the pinning zone Z which was separated from the stock S by the device 181 in the previous machine cycle. It is apparent that in each machine cycle, a tag T is positioned at the pinning zone Z and later in the same cycle a tag T is separated from the stack S.
