Description

[Detailed Description of the Invention] The present invention relates to a spinning machine equipped with an automatic can-changing device such as a drawing machine. More specifically, a spinning sliver connected between an automatically-exchanged full can and an empty can is connected to a coiler plate. The present invention relates to a sliver cutting device that cuts by using a restraint plate that extends in the discharge direction upper part in the full can discharge direction.

Conventional technology The sliver cutting device of a spinning machine equipped with an automatic can changing device is equipped with a restraining plate that presses a part of the upper surface of the sliver of the full can on the discharge side of the coiler plate. Both sides of the transition sliver linked to the can are pressed between the sliver pan of the empty can and the coiler wheel, and by the restraint plate, and in that state due to the tension generated in the transit sliver with the rotation of the empty can and the coiler wheel. I try to cut the sliver. Although the above-mentioned restraining plate acts in a cutting state in a state of being fixed in a horizontal position, heretofore, there have been shown some things in which the restraining plate can be suspended so as not to interfere with maintenance work on the upper part of the coiler plate. For example, in Japanese Utility Model Laid-Open No. 55-58563, a bracket is attached to a coiler plate, a stopper is suspended from a stopper holder attached in the bracket via a pin, and the lower surface of the stopper and the lower end of the bracket can be rotatably suspended. The bent portion of the attached restraint plate is brought into contact with the handle, and a handle extending in the full-can discharge direction above the horizontal position is attached to the center of the stopper, and the handle is operated to move the restraint plate between the horizontal position and the hanging position. What is done is shown. In addition, the actual application filed by the applicant earlier is Shoko 61-24539.
The publication discloses that the restraint plate is configured to be able to be pushed up further from the horizontal position, and the restraint plate is erected to facilitate maintenance of the can transfer section below the coiler plate.

However, in the method of rotating the restraint plate by operating the handle as described above, there is a problem that the device is large and occupies a large space, and in the central portion above the restraint plate in the horizontal position. There is also a problem that it is difficult to operate the handle extending to the restraint plate side. Also, in the case where the restraint plate is configured to be rotatable upward, the restraint plate is simply laid down from the horizontal position to a position where it has an obtuse angle, and therefore the restraint plate falls over for some reason during maintenance of the can transfer section. It was dangerous. The present invention aims to solve such problems.

Means for Solving the Problem A holding member is fixed to a side end portion of a base portion side portion of a restraint plate, and a stopper pin having a knob is held on the holding member so as to be movable in a rotation axis direction of the restraint plate. A spring for urging the stopper pin toward the tip of the pin is interposed between the stopper pin and the holding member, and a coiler plate is provided with a fixing frame located within the movement trajectory of the tip of the stopper pin, and the restraining plate is provided on the fixing frame. In the horizontal state and the upright state, a stopper portion is provided to prevent the rotation of the restraining plate, respectively.

When the stopper plate is hooked to the hook portion in the horizontal state of the action restraining plate, the restraining plate is fixed in the horizontal state and functions as a sliver cutting device. Remove the stopper pin from the latching part, rotate the restraint plate upward, and when it reaches the standing position, the stopper pin, which is urged by the spring toward the pin tip, is automatically latched to the latching part. , The restraint plate is fixed in the standing state. Further, when the restraining plate is in the horizontal state, it can be made to hang down by removing the latching to the latching portion by the stopper pin. Even if the restraint plate is still hanging down, the restraint plate is rotated upward as the full can is moved by the automatic can changing device, and when the horizontal position is reached, the stopper pin automatically springs to the hooking part. It is hooked and the restraining plate is fixed in the horizontal state.

Embodiment 1 In FIG. 1, reference numeral 1 is a coiler plate, on which a well-known coiler head (not shown) including a calender roller, a coiler wheel and the like is installed, and below the coiler plate 1 is a coiler head (not shown). An automatic can changing device (not shown) equipped with a can rotating device that is installed opposite to the can at a distance of approximately the can height is provided at the sliver accommodation position A facing the coiler head (not shown). The sliver spun into the rotating empty can 6b is sequentially accommodated in a coil shape. The can automatic change device (not shown) is composed of a well-known rotating roller, conveyor, etc. When a predetermined amount of sliver is stored in the can at the sliver storage position A, the machine stand is stopped by a full can command and the can is automatically replaced. A device (not shown) is activated to move the full can 6a in the sliver storage position A to the take-out position on the left side of the figure in front of the machine base, and the empty can 6b in the rear from the standby position to the sliver storage position A. It has become. A sliver cutting device 4 is provided on the machine frame front side of the coiler plate 1 for cutting the transition sliver passed between both cans when exchanging the cans. The sliver cutting device 4 will be described below. Coiler plate 1
As shown in FIGS. 2 and 3, fixing frames 7 and 8 are fixed to both ends of the front end of the plate by attaching mounting plates 7a and 8a, which are provided to project in the horizontal direction, with mounting screws 9 and 10. There is. A mounting shaft 13 is mounted between the fixed frames 7 and 8, and a cutter roller 15 having a length substantially equal to the axial length is rotatably provided on the mounting shaft 13. As shown in FIG. 2, a groove 16 is formed on the peripheral surface of the cutter roller 15 so as to be suitable for cutting the sliver. The outer surface 7d of the fixed frame 7 is formed as a flat surface. Reference numeral 20 is a cover that covers the upper portion between the fixed frames 7 and 8, and is attached by screws 21 and 22 to mounting portions 7c and 8c that project horizontally from the fixed frames 7 and 8, respectively. Reference numerals 25 and 26 are holding members pivotally attached to both ends of the mounting shaft 13 outside the fixed frames 7 and 8, respectively.
The holding member 25 is composed of a plate-shaped portion 25a and a holding cylinder 25b concentrically welded to first and second hook portions 17 and 18 which will be described later on the plate-shaped portion 25a. Holding members 25, 2
Mounting plates 25c and 26c are provided at the front end of 6 in a projecting manner in the axial direction, and a restraining plate 30 is mounted to the mounting plates 25c and 26c by mounting screws 31 and 32. A stopper pin 34 having a knob 34a is movably provided in the holding cylinder 25b in the direction of the mounting shaft 13, and a spring 36 is interposed between the flange body 34c mounted on the shaft 34b and the holding cylinder 25b.
The stopper pin 34 is biased toward the tip of the shaft 34b. The fixed frame 7 is provided with a first hooking portion 17 and a second hooking portion 18, which are respectively formed by holes, at positions facing the stopper pin 34 at the horizontal position and the standing position of the restraining plate 30, respectively. In addition, the knob 34a of the stopper pin 34
The rear end portion of the shaft 34b may be directly gripped, and the first and second hook portions 17 and 18 are not limited to the holes. For example, a protrusion may be provided in the direction in which the stopper pin 34 can rotate. You may make it hook by a protrusion.

Next, the operation will be described.

As shown in FIGS. 2 and 3, when the shaft 34b of the stopper pin 34 is inserted and locked in the hole which is the first locking portion 17, the restraining plate 30 is held in a horizontal state. ,
The upper surface of the sliver of the full can 6a taken out from the sliver accommodating position A can be pressed by the restraining plate 30 by an automatic can changing device (not shown), and it can function as the sliver cutting device 4. When the restraining plate 30 is rotated upward, the stopper pin 34 is pulled out from the first hooking portion 17 against the biasing force of the spring, the restraining plate 30 is slightly rotated, and then the stopper pin 34 is released. The tip end contacts the outer surface 7d of the fixed frame 7 by the biasing force of the spring. After that, when the restraint plate 30 is rotated to reach the standing position shown in FIG. 4, the stopper pin 34 moved while contacting the outer surface 7d is automatically latched to the second latching portion 18 by the spring, The restraint plate 30 is fixed in the upright state. As a result, the worker can safely perform maintenance on the rollers of the can transfer unit. In this embodiment, the restraint plate 30
Was fixed to the standing position where it becomes an obtuse angle from the horizontal position, but by setting the position of the second hooking portion 18 as appropriate, it can be fixed at a position perpendicular to the horizontal position or at an obtuse angle position, and therefore restrained. The plate 30 can be fixed at a desired position. Even if the lower end surface of the fixed frame 7 is made flush without providing the protruding portion 7b of the fixed frame 7 and the stopper pin 34 is set to contact the lower end surface in the standing position of FIG. Can be prevented from rotating counterclockwise. First and second by the stopper pin 34
Remove the hooks on the hooks 17 and 18, and set the restraint plate 30 to the fourth position.
Maintenance of the upper part of the coiler plate 1 can be easily performed by rotating the coiler plate 1 to the drooping position shown by a virtual line in the figure. Even if, in the event that the restraint plate 30 is forgotten to return to the horizontal position in the suspended state, the tip end of the shaft 34b of the stopper pin 34 is in contact with the outer surface 7d, the restraint plate 30 is slivered by a sliver can by an automatic can changing device (not shown). When the restraint plate 30 is rotated to the horizontal position while being rotated with the movement of the full 6a taken out from the storage position A, the stopper pin 34 is rotated.
Is automatically hooked to the first hook portion 17. As a result, the restraining plate 30 is fixed in the horizontal position and can function as the sliver cutting device 4.

As described above, in the sliver cutting device of the present invention, the fixing frame provided on the coiler plate is provided with the latching portions for latching the stopper pins of the restraining plate in the horizontal state and the upright state, respectively. , If the stopper plate is locked with the stopper plate horizontal, it can be fixed in the horizontal position and can function as a sliver cutting device, and the stopper plate can be rotated upward to hook the stopper pin. If it is stopped, it can be fixed to the standing position, which can prevent the restraint plate from falling down during maintenance of the can transfer section, and the worker can work safely. Further, a holding member having a stopper pin biased by a spring is fixed to the side end portion of the base side portion of the restraint plate, and a locking portion for locking the stopper pin is provided on the fixed frame. The device installation space can be reduced, and the device can be made compact. After the stopper pin is pulled out against the urging force of the spring by holding the stopper pin, the tip of the pin contacts the fixing frame by the spring, so after removing the stopper pin from the latching part. The stopper pin can be automatically locked and fixed to the latching part by simply rotating the restraint plate. Therefore, the fixing position of the restraint plate can be changed by a simple operation to improve operability. You can
