TECHNICAL FIELD This invention relates to the apparatus for detaching from the web press which supports and supports the remnant of the roll used for a newspaper, a magazine, etc.

Conventionally, the roll is supported by being inserted into a cone of a pair of support arms of a rotary press at a portion of a cylindrical shim.

As shown in FIG. 5, the remaining arm (hereinafter referred to as " remaining core ") remaining after the base of the scroll is removed, the support arm 11 on the moving side is moved among the pair of support arms 11 and 12. FIG. By doing so, the receptacles 13 which are removed from the pair of support arms 11 and 12 and which are raised in advance to the height indicated by the imaginary line supporting the receptacles W are received.

Thereafter, the remnant W is transported to the remnant recovery device (not shown) by the descending and moving of the receptacle receiver 13, and is recovered by the remnant recovery device.

Here, the cross-sectional shape of the receptacle receiver 13 is formed in a V-shape or a U-shaped channel shape and receives only the remnant W, and is not intended to be supported by inserting the remnant W.

In addition, when the conical body 14 of the support arm 11 of the moving side falls, the remnant core W naturally falls from the conical body 15 of the supporting arm 12 of the fixed side. For example, when inserted into the conical body 15, the reverberation W does not escape from the conical body 14 unless the receptacle 13 is lowered to some extent as shown in FIG.

By the way, since the receptacles 13 receive only the remnants W and are not intended to be supported by inserting the remnants W, as shown in FIG. Have.

The present invention provides a lifting frame provided with a guide groove in the up and down direction so as to be lifted up and down, and a pair of clamp arms for supporting a resilient core with a crossover portion where X intersects in the shape of the lift frame. And a spring installed on the pair of clamp arms to apply a force in a direction of closing the pair of clamp arms, and one end connected to each of the clamp arms and the other end rotatably connected to each other so that the guide groove is vertically connected to the guide groove. A pair of clamp actuating levers that can be engaged to be movable to be bent into a V-shape and V-shape, and are installed to be able to move up and down on the lifting frame, the lower end being connected to the pair of clamping levers of the pair of clamp actuating levers. Interlock and descend when the receptacles touch the upper end to move the pair of clamping levers from the reverse V shape to the V shape. The clamp actuating pin for bending and clamping the clamp arm and supporting the pair of clamp arms and the connecting end of the pair of clamp actuating levers protruding from the support frame and descending in a V-shaped state Residual clamp device having clamp release protrusion for preventing the lowering of the connecting end and releasing the operation of clamping the pair of clamping levers from the V-shape to the inverted V-shape to be fitted to the pair of clamp arms The problem was solved.

Normally, the lifting frame descends and waits.

At this time, the pair of clamping levers are inverted V-shaped, and the pair of clamp arms are held by springs, respectively. The clamp actuating pin is pushed up by the connecting end of the pair of clamp actuating levers.

When it is necessary to remove the remnants from the rotary press, the lifting frame rises.

As the lifting frame is raised, the clamp actuating pin is pushed down against the core.

The clamp actuating pin pushes down the connecting end of the pair of clamp actuating levers to bend the shape of the pair of clamp actuating levers from the inverted V-shape to the V-shape.

The bending from the inverted V shape to the V shape is performed in response to the spring elasticity, and the V shape is maintained by the spring elasticity.

Since the pair of clamping levers bends from the inverted V shape to the V shape, the pair of clamping levers approach each other by the elasticity of the spring and support them by inserting the remnants.

Thereafter, the lifting frame is lowered.

The pair of clamp actuation levers also descends together with the lifting frame, but the lower end of the V-shaped clamp actuating lever abuts against the clamp release protrusion during lowering, and the lower end of the pair of clamp actuating levers is prevented. For this reason, the clamp actuating lever bends from the V shape to the inverted V shape and performs a releasing operation to be clamped to the clamp arm, thereby releasing the state of clamping the residual core.

The bending from the V shape to the inverted V shape is also performed in response to the spring elasticity, and the shape of the inverted V is also maintained by the spring elasticity.

When the clamp actuating lever is bent in the inverted V shape, the clamp actuating pin is pushed up by the connecting end of the clamp actuating lever to raise the remnant from the clamp arm to make it easier to recover.

EXAMPLE

Embodiments of the present invention will be described below with reference to FIGS.

The residual centrifugal clamp device 20 (refer to FIG. 3) is combined with the traveling vehicle 21 which loads and conveys a roll.

The residual centrifugal clamp device 20 is a device for moving the residual core W onto the traveling vehicle 21 from a rotary press (not shown).

The resonant clamp device 20 (see FIG. 1) includes a support frame 22, a lifting means 23, a lifting frame 24, a clamp arm 25, a clamp operating lever 26, and a clamp operating pin 27 ), A clamp release protrusion 28, and the like.

The support frame 22 (refer to FIG. 2) is connected to the timing belt 32 which reciprocally circulates by the motor 31 on the traveling vehicle 21, and the pair of rails 33 on the traveling vehicle 21 are shown. , 33) (refer to FIG. 2, FIG. 3) is supported by the roller 53 so that reciprocation is possible.

At the front and rear ends of the support frame 22, the clamp release protrusion 28 is protruded upward. The lifting means 23 is provided on the support frame 22.

The elevating means 23 is an apparatus for elevating the elevating frame 24 onto the supporting frame 22. The elevating means 23 is mainly a pantograph elevating link mechanism 35, and the elevating link mechanism 35 and the supporting frame ( It is comprised between the lifting cylinders 36 which expand and contract the lifting link mechanism 35 provided between 22).

An elevating frame 24 is provided at an upper end of the elevating link mechanism 35.

On the upper surface of the lifting frame 24, a pair of leaf springs 37 pressed and bent by the resonant core W, a switch 38 pressed and actuated by the leaf springs 37, and a pair of supporters for the resonant core W are supported. The support protrusion pieces 39 and 39 are provided.

The support protrusion piece 39 is formed in V shape when seen from the left-right direction in FIG.

At both ends (left and right ends in FIG. 2) of the lifting frame 24, a pair of clamp arms 25 and 25, a grooved plate 40, a pair of clamp operating levers 26 and 26, Clamp actuating pins 27 are provided.

A pair of clamp arms 25 and arms for holding the remaining cores W are rotatably provided at both ends of the support shaft 41 fixed on the lifting frame 24.

The upper end of the pair of clamp arms 25 and 25 (see FIG. 1) is provided with a pad 43 for sandwiching the residual core W, and the pin 44 protrudes from the lower end thereof. One tension spring 45 is suspended between the pins 44 and 44 in a tensioned state.

At the lower ends of the pair of clamp arms 25, 25, one end 47, 47 of the pair of clamp actuating levers 26, 26 is provided by the bolt 48 for rotation freely.

At both ends of the support shaft 41 (refer FIG. 2), the groove | channels 40 and 40 with which the groove was formed are attached. In the grooved plate 40 (see Fig. 1), a guide groove 49 facing upward and downward is formed. The guide groove 49 has the other ends of the pair of clamp actuating levers 26 and 26. The bolt 51 which connects 50 so that rotation is possible is engaged by the up-down movement.

Moreover, the protruding piece 52 bent horizontally is formed in the upper end of the board | substrate 40 in which the groove was formed. The clamping operation pin 27 is provided in the protruding piece 52 so that an up-down movement is possible. The lower end of the clamp actuating pin 27 is in contact with the other end (connection end) 50 of the pair of clamp actuating levers 26 and 26 from its upper part as its own weight. The lower end of the clamp actuating pin 27 may be connected to the bolt 51 (not shown).

Next, the operation will be described.

Usually, the lifting frame 24 descends to the position shown by the solid line of FIG. 2, and waits.

At this time, the tension spring 45 (see FIG. 1) is pulled in the direction in which the lower ends of the pair of clamp arms 25 and 25 approach each other. At the same time, the pair of clamping levers 26, 26 is formed in an inverted V shape. In this state, the bolt 48 of the clamp operating lever 26 is held in contact with the upper end of the guide groove 49.

In addition, the pair of clamp actuation levers 26 and 26 are formed in an inverted V shape to push up the clamp actuation pin 27.

When it is necessary to remove the remnant W from the web press, the traveling vehicle 21 moves just below the remnant W.

Then, the residual centrifugal clamp device 20 operates the lifting cylinder 36 of the lifting means 23 to raise the lifting frame 24.

When the lifting frame 24 ascends to near the position shown by the virtual line in FIG. 2, the clamp actuating pin 27 abuts against the residual core W and is pushed down as the lifting frame 24 continues to rise.

When the clamp actuating pin 27 (refer to FIG. 4) is pushed down, the clamp actuating lever 26 changes shape from the inverted V-shaped state of the solid line to the V-shaped state of the imaginary line.

The other end 50 of the clamp operating lever 26 is guided to the bolt 51 and the guide groove 49 to descend, but the amount of the descending is not limited.

For this reason, the pair of clamp arms 25 and 25 are pulled by the tension spring 45 and rotated until the residual core W is sandwiched and supported.

The angle angle beta when the pair of clamping levers 26, 26 is V-shaped is smaller than the angle angle alpha when the reverse V-shape is inverted.

At the same time, the reverberation core W is supported by a pair of support protrusions 39 and 39 on the lifting frame 24 (see FIG. 2). At the same time, the switch 38 is operated to stop the operation of the lifting cylinder 36.

The remnant core W is sandwiched and supported by the clamp arm 25.

Thereafter, among the pair of support arms of the rotary press holding the resonant core W, the support arm on the moving side falls from the remnant core W.

And the lifting cylinder 36 makes the lifting frame 24 move up and down finely, and makes it easy to pull the remnant W from the pair of support arms of the rotary press.

The motor 31 (see FIG. 2) of the resonant clamp device 20 is operated to move the support frame 22 to one of the left and right directions in FIG. 2 to remove the remnant core W from the support arm on the fixed side. .

In addition, when the pair of support arms of the rotary press simultaneously move to both sides, there is no need to move the support frame 22.

In this way, the remaining core W removed from the pair of support arms of the rotary presser descends integrally with the lifting frame 24 while being held by the clamp arm 25.

The lowering of the lifting frame 24 is performed by the contracting operation of the lifting cylinder 36.

When the lifting frame 24 descends to near the solid line position in Fig. 2, the other end 50 of the V-shaped clamp operating lever 26 (see Fig. 4) abuts against the clamp release protrusion 28, and Only the other end 50 is stopped from falling.

The lifting frame 24 continues to descend further. For this reason, the clamp actuating lever 26 bends from a V shape to an inverted V shape, and performs a releasing operation to be held by the clamp arm 25, thereby releasing the state where the residual core W is fitted.

The bending from the V shape to the reverse V shape is also made in response to the elasticity of the saddle spring 45, and the shape of the reverse V is also maintained by the elasticity of the tension spring 45.

When the clamp actuating lever 26 is bent in a reverse V shape, the clamp actuating pin 27 is pushed up by the other end 50 of the clamp actuating lever 26 to move the remnant core W to the clamp arm 25. Raise from to facilitate recovery.

The remnant W is removed from the rotary press, and the new roll is mounted. The driving vehicle 21 is moved away from the rotary press and moves to the vicinity of the remnant recovery device (not shown). It is recovered by the recovery device.

The resonant clamp device of claim 1 raises the clamp arm to abut the clamp operating pin on the retracted core held by the rotary press, and the retractable core is held by the clamp arm, so that the retracted core is inserted into the cone of the rotary presser. After releasing the support of the reel, the reel can be reliably detached from the reel and can be lowered without dropping the reel.

The resonant clamp device of the present invention is configured to lower the clamp arm supporting the retracted core and to contact the clamp release lever with the clamp operating lever interlocked with the clamp arm to release the clamp arm to release the retentive clamping. In the same manner as the above-described operation of inserting and supporting the remnant, the clamp arm can be reliably inserted or released because the clamp arm is opened and closed.

When the support frame is installed to be movable in a traveling vehicle, as in the resonant clamp device of claim 2, even if the receptacle is inserted into the cone of the rotary press, the retractable core can be moved in the longitudinal direction to withdraw the cone from the cone. I can do it.
