Description

DETAILED DESCRIPTION OF THE INVENTION OBJECTS OF THE INVENTION (INDUSTRIAL APPLICATION) The present invention relates to a slat cutting device for producing slats for blinds.

(Prior Art) Conventionally, slats for blinds have been made by continuously forming long thin aluminum plates and cutting them into predetermined lengths using a slat cutting device. The cutting device uses a feed roller driven by a motor to feed the slat material, and after the slat material has been sent a predetermined length, a cutting machine and a punching machine placed at a predetermined position are operated to cut the slat material to a predetermined length. At the same time as cutting, a lifting cord insertion hole is bored, and the slat thus formed is removed to the side of the slat material transfer path by a slat removal means.

(Problem to be Solved by the Invention) In such a slat cutting device, a dedicated punching machine is installed on the slat material transfer path in case a lifting cord insertion hole is required also in the longitudinal center of the slat. It is being

However, since the cut slats are removed to the side of the slat material transfer path by the removal means, it is not possible to provide a guide member on the side of the slat material. On the other hand, if the slat material is transported in a state where it is shifted in the width direction, there is a problem that the lifting cord insertion hole cannot be drilled at a predetermined position.

Structure of the Invention (Means for Solving the Problems) In order to solve the above problems, the present invention sequentially moves the slat materials using a transfer device, and operates a cutting machine intermittently as the slat materials are transferred. A slat cutting device that cuts a slat of a desired length, uses a drilling machine to drill an elevator load insertion hole in the longitudinal center of the slat, and then uses a removal means to remove the cut slat to the side in the transport direction. The drilling machine 22 is provided with a guide means 24 for guiding the slat material 6 from the side onto its transfer path only during the drilling operation of the drilling machine 22.

With the above means, the slat material 6 is correctly guided to the transfer path by the guide means 24 during the drilling operation of the drilling machine 22, so that the lifting cord insertion hole is accurately bored in the slat 17, and the cut slat 17 is At the time of removal, the guide means 24 is not located on the side of the slat.

) 38. The power switch 34 also operates a pump 39 that sends compressed air to each air cylinder that operates the cutting machine 11, extrusion rod 20, and punching machine 22, and a drive motor 4 that drives the forming rollers 7a and 7b.
0, and each device is powered on by its operation.

A step motor 41 for driving the feed rollers 9a and 9b is connected to the CPU 38 via a drive circuit 42, and a valve device 43 is also connected thereto. The valve device 43 includes the pump 39, the cutting machine 11 and the punching machine 22.
The air cylinders 16, 23 and the rotary actuator 26 are interposed between the pump 39 and the air cylinders 16, 23 and the rotary actuator 26, and the air pressure circuit between the pump 39 and each air cylinder 16, 23 and the rotary actuator 26 is controlled to open and close based on the output signal from the CPU 38. It has become.

A connected program memory 44 connected to the CPU 38 is composed of a read-only memory (ROM), and is connected to the CPU 38.
A program for operating the U38 is stored in advance, and the CPU 38 operates based on the program.

When the length of the slat to be cut and the height of the blind are set using the input keys 30 and 32, the CPU 38 outputs a predetermined number of pulse signals to the drive circuit 42 based on a preset program. By rotating the step motor 41 by a predetermined angle, the feed rollers 9a, 9b
to move the slat material 6 a predetermined length, and then output a signal to the valve device 43 to operate the air cylinder 16 of the cutting ffJIM 11, the air cylinder 23 of the drilling machine 22, and the rotary actuator 26, and push the push rod 20. Activate. By repeating such operations, a predetermined number of slats 17 corresponding to the input blind height are cut.

Next, the operation of the slat manufacturing apparatus 1 configured as described above will be explained.

Now, before starting the slat manufacturing apparatus 1, it is necessary to input the height of the blind to be assembled and the length of the slat 17. Therefore, when the above conditions are input using the input keys 30 and 32 of the control device 4 after operating the power switch 34, the CPU 38 uses the program stored in the program memory 44 in advance to select a slat that is suitable for the slat 3B device 1. The number of slat stages of the blind to be assembled is calculated based on the width of 15 mm and the input value of the height of the blind.

For example, if the slats of the blind to be assembled are long enough to require a cord insertion hole in the center, the perforator operation switch 37 is operated to switch the perforator 22 into the cutter 11. While operating in synchronization, the punching machine 22 is moved to the punching position of the insertion hole.

In this state, when the worker presses the start switch 35,
The CPU 38 outputs a number of pulse signals corresponding to the input slat length to the drive circuit 42 of the step motor 41 to operate the step motor 41 at a predetermined angle, and rotates the feed rollers 9a and 9b to move the slat material 6. Send it to the right in Figure 1. Then, when the step motor 41 is operated at a predetermined angle with the number of pulses based on the length of the slat, then the CP
U38 outputs a signal to the valve device 43 and first the drilling machine 2
The second rotary actuator 26 is operated to rotate the guide plate 24, which is normally located in the state shown by the chain line in FIG. 3, in the direction of the arrow to the position shown by the solid line. In this state, by operating the air cylinders 16.23 and simultaneously operating the cutting device 11 and the punching machine 22, the cutting mold 13
At the same time, a slat 17 of a predetermined length is cut from the slat material 6, and at the same time, an insertion hole is punched in the center of the slat 17 using a punching machine 22.
At step 5, an insertion hole is bored at the rear end of the slat 17 (the left end in FIG. 1) and at the tip of the slat to be cut next.

When the cutting machine 11 and the drilling machine 4R22 are operated to form a slab 1-17 of a predetermined length with holes 141 drilled therein, the CPU 38 outputs a signal to the valve device 43 to move the guide plate 24 as shown in FIG. , by rotating it from the position shown by the solid line to the position shown by the chain line, and projecting this booster 20 forward,
The slat 17 on the support member 19 is pushed down onto the slat receiver 21.

Through the above operations, one slab 1 to 17 is manufactured, and following this operation, the CPU 38 again outputs a pulse signal to the drive J circuit 42 to move the slat material 6, and repeats the above operations. let In this way, when the pre-calculated number of slats are manufactured, the CPU 38
stops the operation of each device.

As described above, if the length of the slat 17 to be cut is input in advance using the input key 24, this slat IJA 3% device 61 can perform step-by-step operations based on the pulse signal corresponding to the input slat length. The motor 35 is rotated to move the slat material 6 a predetermined length, and in this state, the slat material 6 is cut into slats 17 of a desired length by cutting 111. A drilling machine 22 for drilling lifting cord insertion holes in the central portions of the slats 1 to 17 is provided with a guide plate 24 and a guide member 29 to hold the slat material 6 on an accurate transport light path. The plate 24 is rotated to the guide position only during the drilling operation of the drilling machine 22.

Therefore, since the slat material 6 can be positioned on an accurate transfer path, the lifting cord insertion hole can always be drilled at an accurate position in the center of the slat width direction, and the slat 17 can be removed by the extrusion bar 20. It does not interfere with operation.

Effects of the Invention As described in detail above, the present invention exhibits the advantageous effect that the lifting cord insertion hole can be accurately drilled in the cut slat 17 without causing any trouble in removing the cut slat 17.
