Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a blade exchanging device for shirring.

[Problems to be solved by conventional techniques and devices]

Conventionally, in order to replace a shirring blade, as shown in FIG. 5, a mounting member a of one of the upper and lower blades d is inclined by a predetermined angle θ with respect to a horizontal line in a use state. Therefore, as shown in FIG. 6, after the posture is once changed to the vertical state together with the mounting member a connected to the elevating device b such as a press machine, the elevating device b is operated to move the carriage c and the like. The mounting member a is lowered to the position of the blade d placed on the top. Therefore, every time the blade d is mounted on the mounting member a, it is necessary to adjust the angles of the lifting device b and the mounting member a, which is very troublesome. Further, since the heavy attachment member a and the like are lowered, the work itself is very dangerous.

The present invention solves the above-mentioned problems while ensuring safety, reliability, and reliability.
It is an object of the present invention to provide a shirring blade exchanging device capable of swiftly exchanging the blade d.

53 is provided. By rotating the screw shaft 29, the drive member 26 is translated in the left-right direction A along the guide bar 53 while being held in the same posture,
At the same time, the cylinder 3 swings about the front-rear horizontal axis C through the drive member 26, the bush member 31, and the swinging projection 24, as indicated by the phantom line. Also, at this time, front and rear frame 2
The ram 19 slides in the axial direction of the outer tubular portion 18 with respect to the outer tubular portion 18 supported by the 2, 23. In addition, the pivot shaft protruding from the outer cylinder portion 18
The hole of 21 is a pressure fluid supply hole 32 for hydraulic oil or the like. Both sides of the piston part 20 communicate with each other through vertical grooves 33 formed on the outer peripheral surface of the piston part 20.

Rails 34, 34 parallel to the left-right direction A are laid on the upper side of the carriage 5, and the front and rear frames 22, 23 are mounted on the rails 34, 34. Note that 35 and 35 are detachment prevention members provided along the rails 34 and 34.

The reference numeral 7 designates a left-right feed mechanism, and the left-right feed mechanism 7 allows the blade holder 4 to move in the left-right direction A. Specifically, the left and right feed mechanism 7 is a front / rear frame.
Screw shaft 36 rotatably supported on 22,23
And a nut member 38 screwed onto the male screw portion 37 of the screw shaft 36 and fixed to the carriage 5. The feed screw shaft 36 is supported at both ends by the mounting plates 30 like the swinging screw shaft 29.

In FIG. 2, a hook 40 is attached to the tip of the wire 39 suspended from the telescopic horizontal arm 11.
By raising and lowering 40 and expanding and contracting the horizontal arm 11, the electromagnetic magnet 2 is attached to and detached from the mounting portion 12, and as shown by the phantom line, the blade 1 attracted and held by the electromagnetic magnet 2 is moved to a predetermined position. It can be moved. The wire 39 is guided and guided to a winch 42 provided on the rear side of the bogie 5 via pulleys 41 provided on the boom 10 and the like. Reference numeral 54 is an arm expansion / contraction adjusting shaft for expanding / contracting the arm 11. The boom 10 can be manually bent at the position of the pivot shaft 51 in the middle of the proximal end side as shown by the phantom line, and can be tilted rearward in a substantially horizontal state.
It is possible to have nothing at all above. The winch 42 is an example of a manual type, and 43 is an operating lever. A jack 44 is provided at the rear end of the truck 5, and the floor 45 of the truck 5 can be raised and lowered by operating the truck operating handle 9 in the vicinity thereof. A jack (not shown) is also provided at the front end of the carriage 5. Trolley 5
Is driven manually, and parking brakes 47 are attached to the wheels 46 to stop at arbitrary positions. The front and rear frames 22 and 23 are surrounding walls 4 of the cylinder 3, which is a movable part.
Part of 8. A fluid pressure generating device 49 such as a manual pump is arranged between the surrounding wall 48 and the boom 10, and a pressure fluid is supplied to the cylinder 3 from here. 50 is a manual lever. One end of the screw shafts 29 and 36 has a surrounding wall 48
As shown in FIG. 1, both shafts 29, 36 are rotated by an operation lever 52 which is detachable from this portion,
The blade holder 4 can be swung, or the blade holder 4 can be moved in the left-right direction A together with the surrounding wall 48.

Then, as shown in FIGS. 1 and 4, in order to attach the blade 1 held by the electromagnetic magnet 2 to the attachment member D of the shirring device shown by the phantom line, the dolly 5, specifically, After moving the front side where the blade holder 4 is provided to the front surface of the mounting member D, the swing mechanism 6 is operated to swing the blade holder 4 around the front-rear horizontal axis C, The blade 1 is tilted so as to have the same inclination angle θ with respect to the horizontal line of the mounting member D.
After that, the left and right feeding mechanism 7 may be operated to adjust the position of the blade holding base 4 in the left and right direction A, and the blade holding base 4 may be moved to an appropriate position. Furthermore, after this, the floor 45 of the carriage 5 is raised and lowered,
Alternatively, the carriage 5 is appropriately moved forward. Of course, the movement in the left-right direction A may be performed first. In this way, during the work of attaching the blade 1 of the shirring, it is not necessary to move the shirring device at all, and it is possible to perform the attaching work with the attaching member D of the shirring device in the inclined state in the use state. Further, the blade 1 can be attached without touching the blade 1 during the attaching operation. By setting the blade holder 4 at the same angle as the inclination angle θ of the blade holder 4 in advance, the swinging operation performed on the front surface of the shearing device can be omitted, and the blade 1 can be replaced. Can be done more quickly. The inclination angle θ of the blade holder 4 can be attached to the attaching member D with high accuracy and easily by rotating the screw shaft 29.

Of the upper blade and the lower blade, one of the blades 1 mounted horizontally is a wire as shown by an imaginary line in FIG.
By suspending at 39 and adjusting the protruding length of the horizontal arm 11 in the front-back direction B appropriately, another blade holding base 4
Can be attached (not shown).

Unlike the case of the above-described embodiment, movement of the carriage 5, up and down of the floor 45, hoisting and lowering of the wire 39 suspended on the boom 10, swinging,
The left and right feed mechanisms 6 and 7 are electrically operated, or
It is also preferable to use a fluid pressure generator such as hydraulic pressure.

[Effect of device]

Since the present invention is configured as described above, it has the effects described below.

It is possible to replace the upper and lower blades of a large guillotine that are heavy, safely, reliably and quickly.

(Guillotine) The blade 1 can be replaced with the shirring device itself turned off.

In particular, since it is not necessary to touch the blade 1 with hands and the shearing device can be performed in a completely stopped state, it can be said that the safety is extremely high.

Can be used for both upper and lower blade replacement work.
