Description

  The present invention relates to a sheet split winding device, in which a strip-like sheet of plastic fill, paper, metal foil or the like is split into a plurality of strips by a slitter, and the split sheets are distributed and wound around individual winding cores. The present invention relates to an improved mechanism for carrying out a take-up roll of divided sheets.

  Conventionally, in order to reduce the installation area, the sheet split winding device has two upper and lower winding sections that support and rotate the winding core for winding the divided sheets, and the same height as each winding core. The upper and lower touch rollers are arranged, and the take-up roll is formed by winding the divided sheet that is guided on the touch roller and wound around the core, and the touch roller is brought into contact with the take-up roll. There is a type in which the winding core can be moved away from the touch roller in the horizontal direction as the radius of the winding roll increases. As this type of sheet take-up device, the lower take-up unit is used in order to save the work of carrying the take-up roll formed by the upper and lower take-up units out of the machine of the sheet take-up device. On the slitter side of the lower conveyor, a lower conveyor that receives the winding roll formed by the lower winding portion and conveys it in the direction of the winding roll central axis is disposed, and further, on the slitter side of the lower conveyor, There is one in which an upper conveyor that receives a take-up roll formed by an upper take-up portion and conveys it in the direction of the take-up roll central axis is disposed (see the embodiment of FIG. 6 described in Patent Document 1 below).

  However, in this sheet split winding device, the upper conveyor and the lower conveyor have finished taking out all the winding rolls to the machine side after receiving the winding rolls from the respective winding sections, and have a predetermined retraction position. Since the new winding cannot be resumed until the sheet is retracted, the waiting time until the next winding starts after the winding roll has been wound up cannot be shortened. It is impossible to improve the operating rate of the sampling device.

  Further, in the conventional sheet split winding device, in order to save labor for carrying out the winding roll formed by the two upper and lower winding sections to the outside of the machine, the direction perpendicular to the central axis of the winding roll and in the horizontal direction In some cases, a take-up roll transport carriage that is movable on the side of the take-up section is provided on the side opposite to the slitter (see Patent Document 2 below). This take-up roll transport carriage is provided with a vertically movable receiver in two stages, and after receiving the take-up roll released from the take-up unit on the upper and lower receivers, from the take-up unit to the vicinity of the receiving stand Retract and take up the take-up roll from the upper and lower receptacles onto the cradle. And in this sheet | seat division winding apparatus, if a winding roll conveyance trolley retracts | retreats from a winding part and work space is made between a conveyance trolley and a winding part, winding preparation work, such as mounting | wearing of a new core, will be carried out. The winding can be resumed after the completion of the winding preparation work.

  However, since the above-described take-up roll transport carriage is mounted and transported on a receiving device arranged in two upper and lower stages, it is easy to ensure its stability structurally. However, the force which restrains a winding roll on a receiving device also becomes weak. In addition, the take-up roll placed on the upper support is in a high position, and if the take-up roll should fall, it is highly likely that it will suffer pain. Therefore, it is necessary to keep the retracting speed of the take-up roll transport carriage small so that the take-up roll does not fall from the receiving tool due to an inertial force acting on the take-up roll in the transport direction when the transport carriage is accelerated or decelerated. Also, when the upper receptacle is provided so that it can be raised and lowered, there is a lower receptacle below it, so the upper receptacle can be supported only at both ends in the width direction of the belt-like sheet, and the receptacle is supported only at both ends. Since the central portion of the plate is easily bent, it is difficult to obtain a robust support.

  However, in order to ensure the stability and safety of the transport carriage on which a heavy take-up roll is placed, it is necessary to make the carriage, the receiver, the lifting mechanism, etc. large and robust. The occupied space of the take-up roll carriage becomes large and the carriage becomes expensive. For this reason, the take-up roll carriage equipped with a receiving tool in two upper and lower stages is usually applied to a large-sized sheet split take-up apparatus that requires the formation of a take-up roll having a wide width and a large diameter to be processed. However, it is only applied to a sheet split winding device that winds a winding roll having a relatively small weight.

  In order to pass the winding rolls on the upper and lower receivers to the receiving table, first, the winding rolls on the lower receiving member are transferred to the receiving table, and the winding rolls on the receiving table are conveyed to the next step. After lowering and retracting the lower receiving member, the upper receiving member must be lowered and the upper winding roll must be passed to the receiving table. Therefore, it takes a long time to pass all the take-up rolls received from the take-up unit onto the take-up roll transport carriage to the take-up stand, and the operator's restraint time in the take-up roll delivery process by the take-up roll transport carriage In addition, the structure of the take-up roll transport carriage becomes complicated.

Japanese Patent Laid-Open No. 10-175754 JP 2000-247507 A

  In view of the above-described problems, the present invention reliably winds a winding roll wound up by winding sections arranged in two upper and lower stages by a relatively simple mechanism even if it is heavy. It is an object to make it possible to take out to a receiving part behind the take-out part and to shorten the take-out time.

  Therefore, in the present invention, while the strip sheet is divided into a plurality of strips by a slitter, the divided sheets are alternately distributed to the winding sections arranged in two upper and lower stages in the order in which the strip sheets are arranged in the width direction of the strip sheet. In the sheet split winding device that winds up the sheet, the receiving section that receives the winding roll of the split sheet wound up by the winding section once before carrying it out to the next step is the lower winding of the winding section. A delivery device that is provided on the side opposite to the slitter, receives a winding roll from the lower winding unit and passes it to the receiving unit, and is provided between the lower winding unit and the receiving unit, The lower winding unit includes a lower winding support device that supports the winding core, and the lower winding support device moves to the take-up roll release position to the delivery device after stopping the split sheet winding.

Receiving on a member.

  In addition, the receiving unit and the delivery device move forward toward the lower winding unit in order to shorten the distance that the upper and lower core support devices transfer the winding roll after the split sheet winding is stopped. It may be installed on a traveling carriage that can be moved backward.

  In order to enable the received take-up roll to be easily transferred from the load receiving position to the unload position in a short time and to prevent damage to the take-up roll during the transfer, the transfer device is provided with the take-up roll release position. The take-up roll is provided so as to be movable and capable of moving up and down between a load receiving position below the take-up roll supported by the lower core support device moved to the position and a delivery position adjacent to the receiving portion. The thing provided with the movable cradle which mounts a roll is good.

  In addition, even if the split width and split position of the belt-like sheet by the slitter change variously, the winding rolls with various split widths that are supported at various winding positions can be moved from the lower core support device. In order to ensure that it can be received on the cradle and passed to the receiving part, the delivery device includes a plurality of movable cradles for placing the take-up roll, and a plurality of movable cradles for winding. A plurality of support arms individually supporting and guiding in a direction perpendicular to the central axis of the roll, a beam member extending parallel to the central axis of the winding roll, a lifting mechanism for the beam member, and the beam member A support frame that extends along the beam member and has a width shorter than the length of the support arm and a rear portion of the support frame that holds the rear ends of the plurality of support arms so as to be slidable.

It is good to have

  According to the present invention, the winding roll wound up by the upper winding unit is supported by the upper winding core support device and moved above the receiving unit arranged on the side opposite to the slitter of the lower winding unit. Therefore, the delivery device provided between the receiving unit and the lower winding unit needs to pass only the winding roll wound up by the lower winding unit to the receiving unit. The height of the device can be reduced, the occupied space can be reduced, the mechanism for delivering the take-up roll can be simplified, and a safe, inexpensive and robust product can be obtained relatively easily. be able to. Further, the winding core support device can move while supporting the winding core of the winding roll even after stopping the winding of the divided sheets, so that the winding roll can be reliably transferred to the winding roll release position. In addition, it is possible to increase the transfer speed of the take-up roll. And since the upper winding roll passes directly onto the receiving member of the receiving section, it can be quickly unloaded from the receiving section. After that, the delivery device only needs to pass the lower winding roll to the receiving section. The time for passing the take-up roll on the apparatus to the receiving section is halved. Therefore, it is possible to reduce the time from when the take-up roll has been wound up until all the take-up rolls are unloaded from the receiving section. Time can be shortened.
