[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding table cutting device, which automatically cuts a folding table derived from a shaving machine every predetermined length.

[0002]

2. Description of the Related Art A shaving machine for manufacturing a folding table draws out the folding table made into a belt shape. Since the folding table has a standard length, conventionally, an operator manually cuts the folding table led out in a belt shape at a predetermined length with a cutter.

[0003]

[Problems to be Solved by the Invention] However, the cutting work by hand was extremely laborious.

By the way, it is known to set a detecting means for detecting the derived length of the folding table in a shaving machine. This detecting means has a rotor that is grounded on the folding table and rotates in conjunction with its derivation.When the rotor rotates a predetermined number of times, a stamper provided on the peripheral surface of the rotor causes A mark is engraved on the surface of the folding table, and the operator cuts the folding table along the line of the marking with the cutter. Therefore, an object of the present invention is to provide means for automatically cutting a folding table at a predetermined length by using the existing detection means.

[0005]

According to the present invention, the rotor 5 is foldable by grounding it on the surface of the folding table 2 derived from the shaving machine and rotating in association with the derivation of the folding table 2. A cutting device for a folding table, which is set in a shaving machine equipped with a detection means 3 for detecting the derived length of Table 2, and is horizontally arranged in front of the folding table 2 which is drawn out from the shaving machine and descends Guide rail 11 formed of a rack, a sliding unit 15 that slides along the guide rail 11, and a folding table.
Folding 2 sandwiched from the front and back to temporarily stop the descent of front 2
The cutting device was constituted by the holding means 30 for making it. And a motor 16 for driving the sliding unit 15 by a signal from the detecting means 3, and a pinion 17 for sliding the sliding unit 15 along the guide rail 11 by driving the motor 16. And a cutter 19 that cuts the folding table 2 by being driven by the motor 16 to rotate , and the pinionine 17 and the cutter 19 are formed.
And coaxially mounted on the rotary shaft 18 of the motor 16.

[0006]

In the above structure, when the rotor 5 rotates a predetermined number of times, the motor 16 starts driving, the sliding unit 15 slides along the guide rail 11, and the folding table 2 is cut by the cutter 19. . Also in this case, the folding table
The folding table 2 held by the second holding means 30 is temporarily lowered.
The folding table with the cutter 19
2 can be cut horizontally, and in the meanwhile, it can be tapped from the ironing machine.
Stop the derivation of Table 2 and the detection of the derivation length by the detection means 3.
You can continue without letting go.

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is a perspective view of a rear portion of the shaving machine. 1
Is a multi-stage roll, and along this roll 1, a belt-shaped folding table 2 produced by a shaving machine is drawn out.

Reference numeral 3 is a means for detecting the derived length of the folding table 2, which is constructed by mounting the rotor 5 on the bracket 4. A stamper 6 is projectingly provided on the peripheral surface of the rotor 5. The rotor 5 is grounded on the surface of the folding table 2 and rotates as the folding table 2 is drawn out. When the folding table 2 is drawn out for a predetermined length, a stamper 6 imprints a mark. It should be noted that such detection means 3 is well known.

A roll 7 elastically contacts the peripheral surface of the rotor 5. As shown in FIG. 3, the roll 7 is mounted on an arm 8 pivotally supported by the bracket 4, and a micro switch 9 is provided on the back surface thereof. When the rotor 5 rotates in the direction of the arrow and the roll 7 rides on the stamper 6, the micro switch 9 is turned on and it is detected that the rotor 5 has rotated once. The circumference of the rotor 5 is, for example, 65
cm, the rotor 5 rotates 3 times, and the folding table is 65 cm ×
When it is detected that 3 = 195 cm has been led out, the stamper 6 imprints a mark, and the cutter (described later) cuts the folding table 2. Of course, such a set length can be set freely.

In FIG. 1, reference numerals 11 and 12 denote guide rails horizontally provided in front of a folding table 2 hanging from the roll 1. The guide rails 11 and 12 are mounted on a frame 14 on the side of the shaving machine via a support member 13.

A sliding unit 15 is provided with a motor 16 as shown in FIG. The rotary shaft 18 of the motor 16, a pinion 17, the rotary cutter 19 is the same
It is mounted axially . The guide rail 11 is a rack, and the pinion 17 is engaged with the guide rail 11. The roller 20 mounted on the motor 16 via the bracket 21 is fitted to the other guide rail 12. Therefore, when the motor 16 is driven, the pinion 17
And the cutter 19 rotate at the same time , the sliding unit 15 travels along the guide rails 11 and 12, and the folding table 2 is cut by the cutter 19.

In FIG. 1, reference numerals 22 and 23 denote limit switches provided at both ends of the guide rails 11 and 12, respectively.
When the lever is pressed against 23, the driving of the motor 16 is stopped.

In FIGS. 1 and 4, reference numeral 30 denotes a guide rail provided below both ends of the guide rail 11 and led out from the ironing machine.
A holding means for temporarily stopping the downward movement of the folded folding table 2. The holding means 30 includes a solenoid 31.
And a rotary arm 33 attached to the plunger 32 and a fixed arm 34. Both arms 3
3, 34 are provided so as to sandwich the folding table 2 from the front and back. When the plunger 32 of the solenoid 31 is retracted, the rotary arm 33 rotates about the pin 35, and the folding table 2 is held by the tips of both arms 33 and 34.
To stop the descent temporarily.

The present apparatus has the above-mentioned structure, and its operation will be described below. As the folding table 2 is drawn out from the shaving machine, the rotor 5 of the detecting means 3 which is grounded on the folding table 2 rotates. When the rotor 5 rotates a predetermined number of times (for example, 3 rotations or 30 rotations), a signal from the microswitch 9 causes the motor 16 to start driving, and the sliding unit 15 slides along the guide rails 11 and 12. Meanwhile, the folding table 2 is cut by the cutter 19.

In this way, while the folding table 2 is being cut by the cutter 19, the solenoid 31 is also operated and the folding table 2 is held by the rotating arms 33 and 34. In this way, the folding table 2 is held and the lowering of the folding table 2 is stopped.
If it is stopped, it is possible to avoid that the folding table 2 led out from the shaving machine is lowered during cutting by the cutter 19 and is cut by the cutter 19 in an oblique direction. In the meantime
Also, while continuing to derive the folding table 2 from the iron making machine,
The output length of the folding table 2 can be measured by the output means 3.

When the sliding unit 15 slides and the limit switch 22 or 23 is turned on, the driving of the motor 16 is stopped. Here, in FIG. 1, the sliding unit 15
When the sliding unit 15 slides to the left, the motor 16 rotates in the forward direction, and when the sliding unit 15 hits the limit switch 22 and the signal from the micro switch 9 is received next, the motor 16 rotates in the reverse direction. By doing so, the sliding unit 15 can reciprocally slide left and right along the guide rails 11 and 12, and cut the folding table 2 at predetermined intervals. The present invention can be modified in various ways. For example, the position of the sliding unit 15 may be detected by an optical element.
