The action of the original roll lifter for mounting on the original roll holder configured as described above will be described by taking as an example a case where the original roll is fitted to the original roll holder. After numerically inputting the outer diameter dimension of the original roll R to the data input device, when the original roll tray 2 is pulled out in the holder axial direction, the inner shaft 1b of the horizontal guide 1 for the tray is moved by the overhanging end side stopper 8. Stops and the proximity sensor turns on. When the motor 5 is driven as required, the distance t from the axis of the roll roll holder H to the placement surface of the roll roll tray 2 is half of the outer diameter d of the roll roll R which is numerically input to the data input device. The roll roll tray 2 is raised until it matches (radius value). Therefore, when the original fabric roll R is placed on the tray horizontal guide 1, the axial center of the original fabric roll R is aligned with the axial core of the original fabric roll holder H and becomes concentric.
When the original roll tray 2 is pushed inward in the holder axial direction, the core of the original roll R can be fitted into the original roll holder H. The raw roll tray 2 is stopped by the base end stopper 11, the inner shaft 1 b of the tray horizontal guide 1 is stopped by the stopper 13, and upwards by the biasing force of the spring provided on the outer shaft 1 a of the tray horizontal guide 1. When the stopper 12 protruding in the direction is engaged with the concave portion 16 of the inner shaft 1b, the light of the light emitting element 9 is received by the light receiving element 10, and the motor 5 that is turned on is driven reversely as necessary to turn the horizontal guide 1 for the tray. Move down 3 centimeters.
Since the original fabric roll R is separated from the original fabric roll tray 2 by a predetermined height, after the original fabric roll R is supported by the original fabric roll holder H, when the machine is operated, the original fabric roll R is separated from the original fabric roll tray 2. The winding web can be fed out without interference.
[0009]
An embodiment of an original roll lifter for mounting on an original roll holder according to the present invention will be described with reference to FIGS. 2 (a) and 2 (b). The original roll lifter for mounting on the original roll holder according to this embodiment is provided on the lower side of the original roll holder H, and can be adjusted to a required height via the pinion 6 and the rack 7 by driving the motor 5. The horizontal guide for the tray which is positioned at a required height between the elevator 3 and the roll roll holder H and is guided in the vertical direction by being engaged with the vertical guide 15 provided from the elevator 3. 1, a horizontal guide lifting / lowering means 4 comprising an air cylinder device having a stroke of 3 centimeters as a predetermined height which is provided on the lifting / lowering base 3 and lifts and lowers the tray horizontal guide 1, and is engaged and supported by the tray horizontal guide 1. And an original roll roll 2 on which the original roll R can be placed while being guided in the holder axial direction. By adjusting the height of the lifting platform 3 and raising the horizontal guide 1 for the tray with respect to the lifting platform 3 by driving the horizontal guide lifting means 4, the axis of the roll roll R is made to coincide with the axis of the roll holder H. Can do.
The horizontal guide for tray 1 is extendable and contractable, comprising an outer shaft 1a having a slit 1a 'opened upward and an inner shaft 1b having a tray support portion 1b' protruding from the slit 1a 'and supporting the raw roll tray 2. The double roll structure is such that when the roll roll tray 2 is pulled outward in the axial direction of the roll roll holder H, the roll roll tray 2 is extended. Therefore, the tray horizontal guide 1, the outer shaft 1a, and the inner shaft 1b have a double slide structure and can secure a large slide stroke.
When the web roll tray 2 is pulled outward in the axial direction of the web roll holder H and stopped by the overhanging end side stopper 8, the stopper 12 provided on the outer shaft 1a of the horizontal guide for tray 1 is spring-biased. It protrudes upward and engages with the recess 16 of the inner shaft 1b. At this time, the horizontal guide lifting / lowering means 4 is driven to extend when the light of the light emitting element 9 is received by the light receiving element 10 and is turned on, and the horizontal guide for tray 1 is set to a height of 3 cm with respect to the lifting platform 3. Raise. When the tray horizontal guide 1 pushes the original roll roll 2 toward the axial direction proximal end of the original roll holder H, the original roll tray 2 is stopped by the proximal stopper 11 and the inner shaft 1b is stopped. 13 stops contacting. At this time, the horizontal guide elevating means 4 is turned on when the light from the light emitting element 9 is received by the light receiving element 14 and is driven backward to lower the tray horizontal guide 1 by a predetermined height by 3 cm.
The elevator 3 is adjusted to a required height by the motor 5 being driven as required based on the outer diameter of the raw roll R that is numerically input to a data input device (not shown), and is adjusted by the horizontal guide lifting means 4. Along with the rise of the horizontal guide 1 for the tray, the roll roll 2 is moved to the distance between the roll roll holder H shaft axis and the roll roll tray 2 mounting surface numerically input to the computer. The height is raised to a predetermined height so as to coincide with half of the outer diameter dimension (radius value). The height of the elevator 3 is not newly adjusted unless a new numerical value is input after the outer diameter of the raw roll R is input to the data input device. The vertical guide 15 also serves as a lifting guide for the lifting platform 3.
[0010]
The operation of the original roll lifter for mounting on the original roll holder configured as described above will be described by taking as an example the case of fitting the original roll to the original roll holder. After numerically inputting the outer diameter dimension of the raw roll R to the data input device, when the original roll tray 2 is pulled out in the holder axial direction, the inner shaft of the horizontal guide 1 for the tray is stopped by the overhanging end side stopper 8. In addition, the stopper 12 provided on the outer shaft 1a of the horizontal guide 1 for the tray receives an urging force of the spring and protrudes upward to be engaged with the recess 16 of the inner shaft 1b. At this time, the horizontal guide lifting / lowering means 4 is turned on in response to the light of the light emitting element 9 being received by the light receiving element 10 and is driven to extend, and the tray horizontal guide 1 is moved to a predetermined height with respect to the lifting platform 3. Raise 3 centimeters. At the same time, the motor 5 is driven as required so that the pinion 6 meshes and rotates with the rack 7, the elevator 3 is raised, and when the tray horizontal guide 1 is raised, the roll roll is fed from the axis of the roll roll holder H. The distance t to the placement surface of the tray 2 is made to coincide with half (radius value) of the outer diameter dimension of the original roll R that has been numerically input to the data input device. Therefore, when the original fabric roll R is placed on the tray horizontal guide 1, the axial center of the original fabric roll R is coincident with the axial core of the original fabric roll holder H and becomes concentric. When the original roll tray 2 is pushed inward in the holder axial direction, the core of the original roll R can be fitted into the original roll holder H. The light of the light emitting element 9 is received by the light receiving element 14 when the inner roll 1 of the tray horizontal guide 1 is brought into contact with and stopped with the stopper 13 while the original roll tray 2 is in contact with the proximal end stopper 11. Then, the horizontal guide raising / lowering means 4 turned on is reversely driven, and the horizontal guide for tray 1 is lowered by 3 cm as a predetermined height.
Since the original fabric roll R is separated from the original fabric roll tray 2 by a predetermined height, after the original fabric roll R is supported by the original fabric roll holder H, when the machine is operated, the original fabric roll R is separated from the original fabric roll tray 2. The winding web can be fed out without interference.
[0011]
In any of the above examples, the original roll R may be detached from the original roll holder H in order to replace the original roll R with another original roll R before the original roll R becomes small and light enough. At this time, by unwinding the core of the roll roll R by the roll roll holder H and inputting a roll roll R release signal to the computer, the roll roll tray 2 is raised to the roll roll R. You may make it be able to make it a mounting state by touching lightly. In this way, the original roll roll 2 can be pulled out outward in the holder axial direction, and the original roll R can be detached from the original roll holder H. When the original roll R is made small and becomes light enough, when the original roll R is separated from the original roll holder H to be replaced with another original roll R, the original roll tray 2 There is no need to use. In the case where the original roll R is used up and the core of the original roll R is pulled out, and the new original roll R is fitted on the original roll holder H, the outer diameter of the new original roll R immediately before When it is the same as the original outer diameter of the used roll roll R, the roll is adjusted to the outer diameter of the roll roll R set after the roll roll tray 2 is pulled out in the axial direction of the holder. There is no need to readjust the raised position of the roll tray 2.
[0012]
Next, various modifications included in the technical scope of the present invention will be described. In the embodiment of the present invention, the diameter of the raw roll R is inputted to the data input device as a numerical value. When the raw roll tray 2 is pulled out, it automatically rises and can be aligned with the raw roll holder H. In addition, although it is convenient to use when it is pushed down, it is convenient to use. However, it may be configured as an elevating means that can raise and lower the roll roll tray 2 and the elevating platform 3 by operating the handle. Instead of the pinion 6 and the rack 7 of the embodiment, a screw shaft and a nut runner may be used, a motor cylinder capable of multipoint positioning may be used, or a swing lever may be used. The horizontal guide lifting / lowering means 4 is preferably an air cylinder device that can be expected to have a quick response .
The raw roll holder H may be a cantilever shaft and a pair of chucks, and may have a nut structure in which the chucks are manually tightened. When the handle is turned, the preferred roll roll holder H has the three chuck claws of the extension side chuck projecting from the slit of the holder, and the extension side chuck and the proximal end side chuck are close to each other with reference to the center of the interval. Three chuck claws of a structure that chucks the fitted original roll (original roll holder H of Japanese Patent Laid-Open No. 62-167919 or Japanese Patent Laid-Open No. 1-104549), or an extension side chuck when the handle is turned Projecting from the slit of the holder, and while the holder is shortened, the extension side chuck and the base end side chuck approach each other on the basis of the center of the interval to chuck the original roll fitted on the holder No. 2-233442 or JP-A-2-249844, a roll roll holder H].
The tray horizontal guide 1 is preferably stretchable as in the embodiment because the tray horizontal guide does not overhang when the original roll tray 2 is pushed in. However, the tray horizontal guide 1 need not be stretchable.
