Definitions

the present invention relates to a dancer roller device which accumulates a portion of a strip-like material, e.g., continuous strip-like wrapping paper for wrapping cigarettes, and absorbs a difference between feed-in and feed-out amounts of the strip-like material.
a strip-like material e.g., continuous strip-like wrapping paper for wrapping cigarettes
a dancer roller device is often arranged midway along a path for conveying a strip-like material.
the dancer roller device accumulates a portion of a conveyed strip-like material, and when feed-in and feed-out amounts of the strip-like material are different from each other, it absorbs the difference.
the United States Patent US-A-3,682,363 discloses a tape recorder system having a variable capacity tape storage between recording and play-back heads.
the variable capacity tape storage means comprise a carriage member having a plurality of movable tape guide rollers mounted thereon.
a second plurality of stationary guide rollers is mounted on an oppositely opposed cover plate.
the stationary rollers are horizontally staggered relative to the movable rollers.
the carriage member is slidably mounted on a rod to allow vertical movement of the movable guide rollers under actuation of moving means.
the conventional dancer roller device comprises a plurality of stationary guide rollers and a plurality of movable guide rollers. These movable guide rollers can approach or separate from the stationary guide rollers. A strip-like material is extended among these stationary and movable guide rollers in a zigzag manner. The movable guide rollers approach or separate from the stationary guide rollers to change an amount of the strip-like material accumulated in this dancer roller device, thereby absorbing a difference between feed-in and feed-out amounts of the strip-like material.
the present invention has been made to eliminate the drawbacks of the conventional dancer roller device described above, and has as its object to provide an efficient dancer roller device which can facilitate a setting operation of a strip-like material.
a dancer roller device is provided as defined in claim 1.
a strip-like material is extended among the movable and stationary guide rollers in a zigzag manner.
the movable guide rollers are moved to a position above the stationary guide rollers through gaps between adjacent stationary guide rollers. Then, the strip-like material is linearly inserted between these movable and stationary guide rollers. The movable guide rollers are then moved to a position below the stationary guide rollers through gaps between adjacent stationary guide rollers.
the strip-like material can be extended among the stationary and movable guide rollers in a zigzag manner.
a strip-like material can be set by only inserting it between the stationary guide rollers and the movable guide rollers moved to an upper position, and a setting operation of the strip-like material is easy and efficient.
a dancer roller device according to an embodiment of the present invention will be described hereinafter.
the device of this embodiment is a dancer roller device arranged midway along a path for supplying strip-like wrapping paper for wrapping cigarettes.
the dancer roller device shown in Fig. 1 comprises a frame 1.
Three stationary guide rollers 2, for example, are rotatably mounted on an upper portion of the frame 1. These stationary guide rollers 2 are arranged at the same level position to be separated at equal intervals in the horizontal direction.
the dancer roller device comprises four movable guide rollers 4 which are moved together in accordance with a difference between feed-in and feed-out amounts of a strip-like material, i.e., a wrapping material A guided through a plurality of guide rollers 3 which define a portion of a convey path.
the wrapping material A of a predetermined length can be accumulated by these movable guide rollers 4.
the basic operational structure of the movable guide rollers 4 is known to those who are skilled in the art, and a detailed description thereof will be omitted here.
Upper and lower limit sensors 5 and 6 for respectively detecting upper and lower limit positions of the movable guide rollers 4 are fixed on a lower portion of the dancer roller device.
the movable guide rollers 4 are positioned between the upper and lower limit sensors 5 and 6 in accordance with detection signals from the upper and lower limit sensors 5 and 6. More specifically, an unrolling speed of a feed roller (not shown) arranged at an upstream side of the dancer roller device in the convey path is controlled on the basis of the detection signals from the upper and lower limit sensors 5 and 6.
the four movable guide rollers 4 will further be described.
the movable guide rollers 4 are rotatably mounted on a lift carrier 7. Of the movable guide rollers 4, inner two rollers are located below and between the stationary guide rollers 2, and the remaining movable guide rollers 4 are located below and outside the stationary guide rollers 2.
the lift carrier 7 is guided by three guide rods 8 to be vertically movable.
the lift carrier 7 is vertically moved as needed by a rodless cylinder 9 constituting a moving mechanism.
the upward movement limit of the lift carrier 7 by the rodless cylinder 9 is set above the stationary guide rollers 2.
the movable guide rollers 4 can be moved upward beyond the stationary guide rollers 2. In this manner, when the movable guide rollers 4 are located above the stationary guide rollers 2, an insertion path B of the wrapping material A is formed between these stationary and movable guide rollers 2 and 4.
the rodless cylinder 9 When the unrolling operation of the wrapping material A is stopped in the entire convey path, the rodless cylinder 9 is operated. Therefore, the movable guide rollers 4 are moved to a position defined by a sensor 10, thereby preventing the wrapping material A from being folded.
the movable guide rollers can be located at an upper position above the stationary guide rollers, a strip-like material need only be inserted in the insertion path defined between the movable and stationary guide rollers, thus facilitating extension of the strip-like material with respect to the guide rollers.
