Definitions

  • ABSTRACT In coin wrapping apparatus having a plurality of rollers arranged along a path of travel of a wrapper strip around a neat stack of coins to be wrapped thereby. at least the last of the rollers is caused to rotate at a slightly higher speed than the other rollers. whereby the wrapper strip is wrapped tightly and without wrinkles around the circumference of the stack of coins as it is fed around the same between the substantially contacting surface of the rollers and the stack of coins.
  • This invention relates generally to apparatus for wrapping each predetermined number of coins of the same denomination in a neat stack, and in particular to means for preventing a strip of wrapper such as cellophane or the like from slackening as it is guided around the circumference of the stack of coins by a plurality of rollers rotating in substantial contact therewith.
  • the rollers are stationary while the other rollers are made displaceable to urge each new stack of bare coins against the stationary roller and hence to securely hold the stack of coins thereamong.
  • the front tip of the wrapper strip is caught between the first of the rollers and the stack of coins, and as all of the rollers are rotated in the same direction and at the same speed, the wrapper strip is fed around the circumference of the stack of coins by being successively caught between the succeeding rollers and the stack of coins. In this manner the stack of coins is packaged by a predetermined length of the wrapper strip which generally is wrapped several turns around its circumference.
  • the wrapper strip inevitably slackens as its front tip is fed from one of the rollers to the next along the circumference of the stack of coins. While the wrapper strip usually becomes tense again as its front tip is succeedingly caught and pulled by the next roller, this does not necessarily result in the event the wrapper strip slackens too much during travel of its front tip from one of the rollers to the next or in the event the front tip fails to be caught properly by the next roller.
  • the slackened wrapper strip can give rise to wrinkles or improper wrapping of the stack of coins.
  • Another object of the invention is to provide the means of the above described character which can easily be accommodated in coin wrapping apparatus of prior design without any substantial modification of its construction.
  • this invention provides, in coin wrapping apparatus of the type having a plurality of rollers arranged along a path of travel of a wrapper strip around the circumference of a stack of coins and adapted for rotation in substantial contact with the stack of coins to wrap the same with the wrapper strip, that improvement which comprises gearing means adapted to cause at least the last of the rollers to rotate at a higher speed than the other rollers, whereby the wrapper strip is prevented from slackening as it is fed around the circumference of the stack of coins by the rollers.
  • FIG. 1 is an exploded perspective view showing some essential components of coin wrapping apparatus to which the present invention is directed.
  • FIG. 2 is a top plan view showing some of the components of FIG. 1 together with the means for preventing the slackening of a wrapper strip in accordance with the novel concepts of the invention.
  • a coin feed mechanism generally designated by the numeral I comprises a rotary disk 3 for centrifugally sending successive coins out onto a passageway-2 and an endless belt 5 for feeding the coins along the passageway 2 and into a cylindrical coin receptacle 4 while eliminating from the passageway any of the coins having other than the specified diameter and counting only the coins of desired denomination.
  • a coin guide mechanism generally designated by the numeral 6 includes a shutter 9 operatively mounted under the bottom opening of the coin receptacle 4 to support the coins stacked therein and operated by a cam 8 rigidly mounted on a camshaft 7. As a predetermined number of the coins are stacked within the coin receptacle 4 on the shutter 9, a vertically movable guide 10a, which generally defines a wrapping station, becomes operative to direct the stack of coins to a wrapping mechanism 10.
  • the wrapping mechanism 10 comprises a pair of displaceable rollers 11 and 12 and a stationary roller 13.
  • One of the displaceable rollers, I1 is rotatably supported by an arm 19 which can be pivoted around a pin 18 through a link 16 pivotally pinned to a lever 15 which is itself pivoted on a pin 14.
  • the other displaceable roller 12 is rotatably supported by an arm 20 pivotal around the pin 14.
  • the aforesaid lever I5 is urged by a helical tension spring 15a toward a cam 21 fixedly mounted on the camshaft 7 in such a manner that the cam 21 engages a pin I7 on the lever 15 to cause the arms 19 and 20 to turn on their respective pins 18 and 14.
  • the pair of displaceable rollers 11 and 12 are interrelatedly moved toward and away from the fixed roller 13.
  • a stack of coins 22 on the guide 10a are held securely among the rollers ll, 12 and 13 as the rollers 11 and 12 are moved toward the roller 13. All these rollers are rotated in the same direction on their own axes by gears 23a, 23b and 230, respectively, mounted coaxially therewith.
  • gears 23a and 23b coaxial with the displaceable rollers 11 and 12, respectively are of the same diameter and of the same pitch while the gear 23c coaxial with the fixed roller 13 is of smaller diameter and has a fewer number of teeth than the gears 23a and 23c. 4
  • wrapper guide 25 is mounted close to the stationary roller 13 whereas wrapper guides 26 and 27 are so mounted as to move together with the displaceable rollers 11 and 12 respectively.
  • wrapper guides 25, 26 and 27 function cooperatively to guide the front tip of a strip of wrapper 28 around the stack of coins 22 so as to completely encircle the same.
  • a wrapper feed mechanism generally designated by the numeral 29, includes a shaft or rod 30 on which the wrapper strip 28 is held in a roll.
  • a drive roller 32 cooperates with an idler roller 31 to feed the wrapper strip 28 toward the aforesaid rollers 11, 12 and 13.
  • a guide plate 33 FIG. 2, extends between the drive roller 31 and the stationary roller 13 to guide the wrapper strip 28 toward the latter and is pivoted on a rod 33a.
  • a cutter 34 mounted in opposition to the guide plate 33 has a number of teeth on its substantially V-shaped edge to cut the wrapper strip 28 at each predetermined length.
  • the drive roller 32 rotating in synchronism with the camshaft 7, becomes operative to feed the front tip of the wrapper strip from its first standby position intermediate between the cutter 34 and the displaceable roller 11 to a second standby position between the rollers 11 and 13, thereby making the wrapper strip ready for the next wrapping operation.
  • the drive mechanism of this coin wrapping apparatus is such that a gear 37 fixedly mounted on a drive shaft 36 having a gear 35 rotated by a motor, not shown, is meshed'with a gear 38 fixedly mounted on the camshaft 7.
  • This camshaft is associated with the guide a in such a manner that when the latter has been elevated to its predetermined position under the shutter 9, the cam 8 of the camshaft 7 operates to open the shutter 9 so that the stack of coins is caused to rest on the guide 10a.
  • the guide 10a is lowered together with the motion of the camshaft 7 to carry the stack of coins 22 down to the wrapping mechanism 10.
  • the cam 21 disengages the pin 17 of the lever to permit the same to be turned by the helical tension spring 15a. Since, at this time the arms 19 and are also turned on their respective pins 18 and 14, the displaceable rollers 11 and 12 are both moved toward the stationary roller 13 to retain the stack of coins 22 in position.
  • a gear 39 in mesh with the gear 37 on the drive shaft 36 is meshed with a gear 40 which in turn is meshed with a gear 41 mounted on the pin 18 to be meshed with the gears 23a and 230 of the rollers 11 and 13, respectively, so that these two rollers are rotated by the train of gears 37, 39, 40 and 41.
  • the aforementioned gear 35 on the drive shaft 36 is meshed with a gear 42 mounted on the pin 14, and this gear 42 is meshed through the gear 23b with a gear 43, so that the roller 12 is rotated by the train of gears 35, 42 and 43.
  • the fixed roller 13 is rotated at a faster speed than the displaceable rollers 11 and 12.
  • each predetermined number of coins which have been arranged into a neat stack by the coin feed mechanism 1 are carried by the guide 10a to the wrapping mechanism 10.
  • the cam 21 of the camshaft 7 actuates the lever 15 to cause the displaceable rollers 11 and 12 to move toward the stationary roller 13. Since the front tip of the wrapper strip 28 has already been fed to the displaceable roller 11 by the pair of rollers 31 and 32 of the wrapper feed mechanism.29, the front tip of the wrapper strip is caught between the stack of coins 22 and the displaceable roller 11 as the displaceable rollers 11 and 12 are moved toward the stationary roller 13.
  • the displaceable roller 11 is then rotated at a higher speed than the drive roller 32 in accordance with the prior art, so that the wrapper strip 28 is severed at a predetermined length by the cutter 34 due to its own tension.
  • the predetermined length of the wrapper strip 28 is then directed along the wrapper guides 26 and 27 until its front tip becomes caught between the next displaceable roller 12 and the stack of coins 22. Since the displaceable roller 12 is also in rotation together with the stack of coins 22, the wrapper strip 28 is further directed along the wrapper guides 27 and 25 until its front tip becomes caught between the last roller 13 and the stack of coins 22. By the repetition of this procedure, the wrapper strip 28 is wrapped several turns around the stack of coins 22.
  • lever means operatively connected to said displacable rollers and integrating their simultaneous movement for positioning these rollers relative to the wrapping station and said fixed roller; power means for rotating the rollers at the wrapping station; control means for orienting the displacable rollers relative to the wrapping station and oriented coins; guide means at the periphery of each of the respective rollers extending partially around and disposed in series about the wrapping station for progressively engaging the leading end of a wrapper segment and directing it to the series of rollers and oriented coinse for convoluting the wrapper segment about the coins at the wrapping station.
  • the guide means for said displacable rollers being connected to and movable with the lever means integrating simultaneous movement of said displacable rollers.
  • said power means including force transmitting portions for rotating one displacable roller located at a position with said guide means adapted to guide the leading tip end portion of the wrapping segment at a peripheral speed slightly lower than that of the succeeding roller for maintaining a wrapper segment in substantial tension and eliminating intermediate wrinkles in the wrapper segment as the leading tip end portion thereof successively engages the series of guide means.
  • said force transmitting portions comprises trains of intermeshed gears operatively connected to a common drive gear, said trains of gears including drive gears operatively connected to the series of rollers and having diameter and gear-tooth ratios for affording peripheral speeds increased from the first to the last roller of the series of rollers.
