ある。In this case, a shear pusher is used as roll holder, which is movable in a hollow shaft which is rotatably mounted in the rolling head and is connected to the hollow shaft in a rotationally fixed manner. There is. In this case, the roll is tightened by a tightening bolt that passes through the sliding bushing and engages the head with a raised surface formed in the sliding bushing, and the thread of the tightening bolt is vertical. It is screwed into the mounting member, and the threading member eye material passes through a hole formed in the center of the roll and is attached vertically with a nut. A chamber sealed by a lip seal is formed between the tightening surface formed on the sliding push and the end surface of the tightening member screwed to the tightening bolt. Media can be introduced. The pressure medium introduced into the chamber applies a load to the propagation surface of the sliding bushing and the end surface of the vertically attached member, and applies a tensile stress to the vertically attached bolt, causing the vertically attached bolt to elongate. In this way,
The threading force generated by the nut is partially offset, and the load on the thread supporting the threading force is reduced. Therefore, the nut buried in the end face of the roll can be easily unscrewed for roll replacement. The tightening bolt can be loaded in the same manner to increase the roll. That is, first hold the roll in place,
Insert the vertical mounting member and screw it onto the cotton bolt. The nut is then screwed on and tightened vertically with a wrench, after which a pressure medium is introduced into the chamber and the vertical bolt is stretched somewhat. In this state, the nut can be further threaded with a small amount of force. When the pressure medium is discharged from the said chamber, the clamping bolt tries to retract again, which causes the roll to move against the roll holder, in this case the sliding bush,
is tightened with a sufficiently large force. Although this device is satisfactory in terms of its operation, it is complicated and expensive, and it is difficult to insert the vertical member into the roll, especially since the vertical member must be fitted very accurately to the roll. It is.

得るようにすることである。It takes time to unscrew the nuts that hold the rolls in place. Furthermore, when the roll is removed, the threads for the nuts formed on the cotton-attached member are exposed and protrude from the roll holder, making them easy to damage. In addition, the threaded joint between the vertical member and the nut is easily damaged during rolling operations, and deformation of the thread may make it extremely difficult to unscrew the nut. The object of the invention is to improve a device of the type mentioned at the outset, to make it simpler in construction and cheaper to manufacture, as well as to eliminate the risk of damage and to allow roll changes to be carried out simply and easily. It is.

わずかである。In order to achieve this object, the present invention has a configuration in which the connecting member is rotatably supported in a cylinder fitted to the roll holder, and has a hammer head on the roll side, and a connecting member formed on the roll and the hammer head. A bayonet coupling mechanism is formed by the introduction and closing of the mouth. In this case, the end face of the hammer head can have a spanner-engaging hole for a spanner inserted through a hole formed in the center of the roll. The hole formed in the center of the roll can be kept closed by a screw cover. Furthermore, it is also possible for the connecting member section, which projects from the tensioning surface of the roll facing the roll holder, to have a spanner-engaging surface for a universal spanner. The end of the coupling member facing away from the roll can be configured as a piston that is movable in a pressure medium cylinder which is arranged immovably in the roll holder and which tensions the roll in the roll holder. The spring which generates the spring force for the fixation can also be configured as a bamboo spring that surrounds the connecting member and is supported at one end by the disk of the cylinder opening and at the other end by the collar of the continuous member. can. In a particularly advantageous embodiment of the invention, the connection village with the bamboo shoot spring is arranged in a cup-shaped bushing consisting of two cylinder sections of different diameters, the smaller diameter cylinder section being at the bottom of the cup-shaped bushing. forming a pressure medium cylinder, the large diameter cylinder section being fixed to the roll holder by a radially outwardly directed ring flange. The device according to the invention is not only simple in structure and inexpensive to manufacture, but also the hammer head of the connecting member is difficult to damage and only protrudes from the roll holder by a small amount when the roll is removed.

ル保持体１に緊定している。A cup-shaped bush consisting of two cylinder sections 6a and 6b of different diameters is inserted into the opening 5 of the roll holder facing the roll 4.
This is screwed to the end surface 5a of the roll holder 1 by a ring flange 6c on the roll 4 side. The cylinder section 6b of the cup-shaped bushing has a bottom 6d and forms a pressure medium cylinder for the end of the coupling element 7, which is designed as a piston 7a. The connecting member 7 passes through a hole 8a in the center of the disc 8 that covers the opening □ of the cylinder section 6a on the side of the roll 4, and the hammer head 7b attached to the connecting member passes through the hole 8a in the center of the roll 4. It's going inside. As can be seen from FIG. 2, a spanner engaging hole 7c is formed in the roll-side end surface of the hammer head 7b, and the end of the spanner that is inserted through the center hole 4b of the roll 4 is inserted into the spanner. By engaging in the engagement hole 7c, the hammer head can be pivoted to the connection position shown by a solid line or the disengagement position shown by a broken line with respect to the introduction opening 4c on the roll holder side of the roll 4. Furthermore, a bamboo shoot spring 9 is arranged within the cylinder section 6a of the cup-shaped bushing;
One end thereof is supported by a disk 8, while the other end is supported by a collar 7e provided on the connecting member 7. In the illustrated tensioned state, the hasoma head 7b of the connecting member 7 is attracted to the tensioning surface on the side of the introduction entrance 4c by the bamboo shoot spring 9, thereby tensioning the roll 4 to the roll holder 1. There is.

。When removing the roll, pressure medium is first introduced into the pressure medium cylinder formed by cylinder section 6b. This pressure medium exerts a force on the piston 7a against the force of the bamboo shoot spring 9, thereby loosening the tension on the hammer head 7b, so that the hammer head 7b can be moved into position in FIG. It can be rotated into the release position shown in broken lines and the roll 4 can therefore be easily pulled off from the roll holder 1. new. When the pressure medium is released after the hammer head is rotated again to the connection position shown by the solid line in FIG. It is returned to the normal position layer shown in the figure. The central hole 4b of the roll 4 can be kept closed by a screw cover 10. The hammer head 7b can also be rotated using a flat adjustable spanner instead of the insertion type spanner.
