Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic wire cutting machine that automatically and continuously cuts the edge of a workpiece material, such as the upper of a shoe.

BACKGROUND ART Conventionally, in edge paper machines that cut edges of workpiece materials such as shoe uppers, the workpiece materials were fed one by one by hand, and the workpiece materials were hand-handled as they were made.

For this reason, it is difficult to uniformly cut the outer periphery of the upper workpiece material, which requires skill, and there are shortcomings such as poor working efficiency.

SUMMARY OF THE INVENTION An object of the present invention is to provide an automatic edging machine that improves the drawbacks of the conventional edging machine as described above.

Embodiments of the present invention will be described in detail below with reference to the drawings.

In FIG. 1, reference numeral 1 designates a workpiece material storage section, and this storage section has a casing 3 having a door 2 that can be opened and closed at the top of the front, as is clear from reference to FIG. An electric cylinder 5 having a slidable operating rod 4 is arranged so as to extend in the vertical direction.

At the free end of the operating rod 4, a horizontal receiving plate 7 for receiving a stack 6 of workpiece materials A whose edges are to be machined is arranged, and at the upper part of this receiving plate 7, for example, A stack of workpiece materials 6 consisting of a pair of light-emitting elements and a light-receiving element
First and second detectors 8 and 9 are arranged to detect the height position of.

Further, in the fixed part 11 arranged in the center, there are a detector 12, for example, a microswitch, which detects the lowest position of the horizontal receiving plate 7 and therefore the operating rod 4, and a detector, for example, a microswitch, which detects the opening and closing of the door 2. 13 are arranged.

Therefore, when the electric cylinder 5 is activated and the operating rod 4 is moved upward, and the top surface of the stack of materials 6 reaches the position of the detector 8, no output is obtained from the detector 8, and the electric cylinder 5 is no longer activated. When the stack 6 is stopped and the upper surface of the stack 6 reaches the position of the detector 9, the output from the detector 9 is no longer obtained, and the electric cylinder 5 is activated contrary to the above, and the horizontal receiving plate 7 and therefore The stack 6 descends and the detector 8
When the output from the detector 8 is obtained, the electric cylinder 5 is activated again and the stack 6 rises, and in the end, the upper surface of the stack 6, that is, the uppermost workpiece is always detected by the detector 8. and 9.

Further, when the horizontal receiving plate 7 is lowered and the detector 12 is energized, the energizing state of the electric cylinder 5 is stopped, and when the door 2 is opened and this is detected by the detector 13, the horizontal receiving plate is energized. Regardless of the position of 7, the electric cylinder 5 is energized so that the horizontal receiving plate 7 comes to the lowest position where the detector 12 is energized.

Reference numeral 15 indicates a material supplying means disposed at a rear position of the material storage section 1 described above, and this means has an operating rod 16 that is slidable in the front-rear direction and a control signal generating circuit (not shown). The cylinder 17 is energized by a control signal from the cylinder 17, and the operating rod 18 is provided at the free end of the operating rod 16 and is slidable in the vertical direction. The pickup cylinder 19 is energized by a signal, and the above-mentioned product is generated by a control signal from the control signal generation circuit described above, which is connected to the vacuum generator (not shown) and is provided at the free end of the operating rod 18 of the pickup cylinder 19. It has two vacuum tongues 21 that adsorb the workpieces one by one from the heavy body 6.

In this case, when the operating rod 16 of the cylinder 17 is in the backward sliding position, the vacuum tongue 21 is moved to the guide means 2 which will be described later.
5, and when the operating rod 16 is in the forward sliding position, the cylinder 19 is placed on the material of the stack 6 placed in the material storage section 1, which will be described later. The operating rod 1 is energized as shown in Figure 5B.
If a control signal is obtained from the control signal generation circuit while the cylinder 8 is in the forward sliding position, the cylinder 19 moves at the time t as shown in FIG. 5B.

The actuating rod 18 is lowered and the vacuum tongue 21 is lowered onto the material to be laminated on the receiving part 1, while the vacuum tongue 21
As shown in FIG. 5C, the cylinders 17 and 19 are energized and the vacuum generator is operated simultaneously, so that the material is attracted, so that the material is attracted by the vacuum tongue 21, and then the control signal generation circuit generates the next material. If a control signal of t is obtained, the cylinder 19 is activated at time t.

At a later point in time t1, the actuating rod 18 is energized contrary to what is described above, and its operating rod 18 is raised, and at a point in time t2 after the point in time t1, the cylinder 17 is energized.
Contrary to what has been described above, is energized and the operating rod 16 is placed in the backward sliding position, and furthermore, at time t3 after time t2, the vacuum generator becomes inactive and the vacuum outlet 21 has been sucked until now. The material that was being held is dropped onto the bed 26 of the guide means 25.

The guide means 25 includes a bed 26 whose upper surface bulges upward and is curved to receive the material A supplied by the above-mentioned supply stage 15, and an engagement piece 2 at the free end which is slidable in the front and back direction.
Positioning cylinder 29 with actuating stroke 28 provided with 7
and an auxiliary feed roller 33 connected to an auxiliary feed motor 32 so as to be slidable up and down by an auxiliary feed cylinder 31.
It is rotatably pivoted to a fixed part 34 provided at the seventh part of the bed 26, has an engaging element 36 at its free end that extends into a through hole 35 provided in advance in the bed 26, and has a reflecting plate 3γ. and a rotating arm 38 (sixth
), a light emitting element 39 and a light receiving element 40 detect the rotating position of the rotating arm 38 depending on whether or not the reflecting plate 37 is present.
and a mork-driven socket roller having an outer solid surface that is curved with the same curvature as the bed 26 and located on the right side of the engaging member 36 of the rotating arm 38 when viewed in FIG. 43 and a presser roller disposed so as to be slidable up and down (its guide means not shown); 44, which clamps the material and transfers it from the left to the right as seen in FIG. The feed roller means 45 and the rotary arm 38 are arranged on the bed 26 at the flow position, that is, the left side position as seen in FIGS. KANO: The detector 42 for detection, the operation of the cylinder 48 attached to the fixed part 34, and the motor 50 attached to the free end of the rod 49 are used to detect the third point in the plane orthogonal to the direction of material transfer.
A roller 51 that is rotated counterclockwise as seen in the figure;
The fixed portion 34 is disposed at a position in front of the feed roller means 45.
An actuator 52 that is slidable in the vertical direction and is fixed to the
A hemispherical pivot 53 provided at the free end of the actuator 52 of a solenoid having ing.

When the material is supplied onto the bed 26 by the feeding stage 15, the positioning cylinder 29 is energized at time t4 after time t3, as shown in FIG.
}. is located at a predetermined position, that is, at a position where the rear edge faces the engager 36 of the rotating arm 38, and returns to its original position at time t after a predetermined time, and then at time t6 after time t5, the auxiliary feed cylinder 31
is energized as shown in FIG. 5E, and the auxiliary feed roller 33 descends to come into contact with the material from above, and then the auxiliary feed motor 32 is energized at time t7 after time t6 as shown in FIG. 5F. Then, the roller 33 rotates to transfer the material to the right side, that is, to the side of the feed roller means 45, and at the same time, the receiving roller 43 of the feed roller 45 is driven to rotate at time t7, as shown in FIG. 5G, to sandwich the material. Move it to the right side due to the relationship.

The auxiliary feed cylinder 31 and the motor 32 are returned to their original state at a time t8 after the time I7, and the feed roller means 45 is stopped at a time tto after the end detector 54 generates an out-of-material signal, that is, an end signal. ing.

When the material is being transported to the right by the feed roller means 45 and the edge of the material is concave, that is, the rear edge of the material has a curved shape that gradually bulges rearward as shown in FIG. As the material is transferred, the detector 42 is worn by the material, and a detection signal is obtained from the detector 42. Based on this, the cylinder 48 is energized and the roller 51 descends to press the material. .

When the material is further transferred to the right by the feed roller means 45, the rear edge of the material A engages with its engager 36, so that the rotating arm 38 rotates counterclockwise against the spring 34. , in response to this, the detection output from the detector 41 is no longer obtained, and based on this, the motor 50 is energized and the roller 51 is moved to the third position.
The material is rotated in a counterclockwise direction as viewed in the figure, and the entire material is rotated in a counterclockwise direction as seen in FIG.

When this occurs, the rotating arm 38 returns to its original position by the force of the spring 34 and a detection output is obtained from the detector 41, so that the motor 50 is deenergized and the rotation of the roller 51 is stopped.

At this time, the edge of the material comes to align with the feeding direction.

When the material is further transferred to the right by the feed roller 45, the material rotates clockwise as seen in FIG. 7 due to the cooperative action of the feed roller 45 and the roller 51. As a result, the rotating arm 38 is rotated counterclockwise and no signal is obtained, so the roller 51 rotates and the material is moved to the engager 3 of the rotating arm 38.
6 to separate them forward.

Thereafter, the same operation is repeated as long as the detector 42 is covered to guide the material. When the detector 42 is no longer covered, the cylinder 48 is reversely energized and its operating stroke 49 returns to its original position above. Return.

Also, if the rear edge of the material has a convex shape, that is, a curve that gradually bulges toward the front, as shown in FIG. 8, contrary to the case described above in FIG. 7, the detector? 2 is not covered by the material, so no detection output can be obtained, contrary to the concave shape.

Furthermore, as shown by the solid line in FIG. 8, when the material presses the engagement element and no protrusion output is obtained from the detector 41, the pins 1 and 53 are located at an upper position where they do not come into contact with the material. Also, in such a state, the material is transferred to the right by the feed roller 45, and the material is separated from the engager 36 of the rotating arm 38, and the rotating arm 38 returns to its original position by the force of the spring 34, and the detector Since the detection output can be obtained from 41,
The solenoid is energized and its actuating rod 52, and thus the pivot 53, descend to hold down the material.

This is because the position of the pivot 53 is on the front side of the feeder roller 45, so that the material is rotated clockwise around the position of the pivot 53, so that the outer and inner edges of the material are aligned with the engagement members of the rotating arm 38. 36 and rotates counterclockwise, the detector 41 no longer outputs a detection output, which deactivates the solenoid and causes the pivot point 53 to rotate counterclockwise.
returns to its original position above, and this operation is repeated thereafter to guide the material.

Reference numeral 60 indicates a paper-making means, and this paper-making means has a known form including an arm-shaped cutter 61.

Since this paper-making means is well known, detailed explanation thereof will be omitted.

The cutter 61 cooperates with the feed roller means 45 to cut the edges of the material.

Reference numeral 65 denotes a take-out means for taking out the material made by the above-mentioned paper making means 60, which includes a rotary cylinder 66 rotatably disposed on the fixed part, and a rotary cylinder 66 provided at the free end slidable in the upper F direction. It has a structure comprising a big up cylinder 68 having a working rod 67, and a vacuum tongue 69 similar to the above-mentioned supply stage 15 attached to the free end of the working rod 67.

In this case, the rotary cylinder 66 assumes a rotational position in which the vacuum mouth 69 is located to the right of the cutter 61 in the normal non-energized state, but when it is energized from such a state, the vacuum tongue 69 moves as will be described later. It is designed to take a rotational position that exists on the storage section 70.

Thus, the cylinder 68 reaches the point t when the feed roller 45 stops.
io, the vacuum tongue 69 is energized and lowered onto the material as shown in FIG. 51, and at the same time, the vacuum generator is activated as shown in FIG. Therefore, the material is adsorbed by the vacuum outlet 69, and then, at time t1 after time tlO, the cylinder 68 is deenergized and the vacuum outlet 69 is sucked. 9 rises with the material adsorbed,
At time t1, which is slightly later than this, the rotary cylinder 66 is energized as shown in FIG. At time tl3, which is slightly later than tl2, the vacuum generator is deactivated and the material held by the vacuum bellows 69 so far is allowed to fall.

Furthermore, 70 indicates a storage section, which has the same configuration as the material storage section 1 described above.

Reference numeral 80 is a controller that controls the operation of the paper machine.

As described above, according to the present invention, once the materials are stacked and stored in the material storage section 1, the edges of the materials are automatically cut and stored in the storage section 70. No manpower is required to cut the material, so no skill is required, work efficiency can be improved, and moreover, one worker can operate several devices, resulting in labor savings.

In addition, since the guide step 25 detects the edge of the material and guides it according to its shape, the edge of the material 6 can be cut with a uniform width without any restrictions on the shape of the material. There are practical benefits such as being able to

Although only one embodiment of the present invention has been described above, the present invention is not limited thereto and can be modified and changed in various ways.
