Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a width adjusting device for a plate material storage frame in which the width of the plate material storage frame is adjusted by a machine.

[Conventional technology]

FIG. 3 shows a plate material storage frame. In the figure, 1 is a seat plate, 2
Is a fixed plate attached thereto, 3 is a column, 4 is a fixed plate tightening screw, 6 is a movable plate, 5 is a movable plate tightening screw, and 7 is a top plate 8.
Also, elongated holes provided in the seat plate 1 and 9 are plate materials to be stored. The movable plate 6 can be moved along the elongated hole 7 by loosening the screws 5 (four of which are provided above and below).

Next, the operation will be described. When moving the movable plate 6, a person loosens the screw 5 with a tool. There are four screws 5, two above and two below.

Next, a person moves the movable plate 6 to an appropriate position to insert the plate material 9. At a position where the plate member 9 can be smoothly stored, when a person tightens the screw 5 with a tool, the width adjustment is completed.

[Problems to be solved by the device]

Since the width of the conventional plate material storage frame has been manually adjusted, it must be adjusted according to the plate material to be stored, the plate material is always required, and the screw tightening tool is also required. Further, fixing the movable plate according to the plate material depends on the skill of the operator, and there is a problem that it takes a long time to adjust the width and the parallelism (accuracy) with the fixed plate is poor. .

The present invention has been made in order to solve the above problems, and an object thereof is to obtain a device that can perform width adjustment quickly and accurately and does not require the skill of an operator.

[Means for Solving the Problems]

A width adjusting device for a plate material storage frame according to the present invention includes an automatic driver for tightening and loosening screws for supporting and fixing a movable plate on a column configured to move itself.
For example, a suction pad to be attached to and detached from the movable plate and a contact plate for hitting the movable plate to detect the current position of the movable plate are provided so that the position adjustment of the movable plate, which was conventionally performed manually, can be performed automatically. I have to.

[Action]

The width adjusting device for the plate material storage frame in this invention moves the column, calculates the position to move the plate from the position where it abuts the movable plate, and loosens the screw with an automatic screwdriver.
Adsorb the movable plate with the adsorption pad, move the column again, change the position of the movable plate, and tighten the screw at that position with an automatic screwdriver.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 20 is a stand, 21 is a surface plate installed on this, 15
Is a roller for taking in and sending out the plate material storage frame 22 shown in FIG. 3, and 17 is a column for fixing the material storage frame 22.
Although not shown, it has a sensor for detecting the frame, a stop cylinder for stopping the frame at a fixed position, a pressing cylinder for fixing the frame at the fixed position, and the like. Reference numeral 10 is a U-shaped column, which is connected to a slide block 23 and is adapted to move forward and backward on a rail 26 by a feed screw 25 of a servomotor 24. The servomotor 24 is capable of sufficiently driving the traveling load of the column 10, and has a certain torque limitation so that the driving force is not output under a load larger than that. Therefore, when the load becomes larger than the traveling load, the load is stopped in balance with the reaction force. 11 is a column
A contact plate provided in the vertical portion of 10, a suction pad 13 that can be moved forward and backward by a cylinder 12 also provided in the vertical portion of column 10, 14 is an electric screwdriver provided at the top and bottom ends of column 10, 19 is a cylinder for moving the driver 14 up and down, 27 is a slide block, and 28 is a driver bit.

FIG. 2 is an enlarged view of the main part of this invention.
16 is a stopper cylinder, and 18 is a frame pressing cylinder.

Next, the operation will be described. First, the transport roller 15 rotates in order to take the plate material storage frame 22 into the machine. When the conveyed frame 22 comes close to the fixed position, it is detected by the sensor and the stopper cylinder 16 shown in FIG.
Stop. Then, press the frame 22 against the fixed column 17 and press the cylinder.
Press at 18 to position and fix in place.

After the frame 22 is fixed, the servo motor 24 shown in FIG.
Is activated and column 10 is moved forward. At this time, column 10
When the hitting plate 11 provided at the position hits the movable plate 6 at an arbitrary position of the frame 22, the control device of the servo motor 24 detects the movable plate 6 and the servo motor 24 detects a reaction force with the movable plate 6. Stop in balance. Then, attach the suction pad 13 to the cylinder 12
Then, the movable plate 6 is adsorbed by the vacuum, and then pulled up by the cylinder 12 and fixed to the column 10 side so as to be pressed against the contact plate 11.

Next, when the movable driver 6 is pressed against the contact plate 11 and the electric screwdriver 14 that is set to a position directly above (immediately below) the movable plate tightening screw 5 is taken out by the cylinder 19, The driver bit 28 is inserted into the head of the screw 5. Thereafter, when the electric screwdriver 14 is rotated in the reverse direction (loosening direction), the screw 5 is loosened and the movable plate 6 is released from the frame 22. At this time, since the cylinder 12 is driven by the suction pad 13 to be attracted by vacuum attraction, the movable plate is brought into contact with the contact plate 11 and becomes parallel to the fixed plate 2. Also, the current position of the movable plate 6 can be known from the stop position of the servo motor 24 by the control unit of this device.

Next, the width is adjusted. An operator calculates the width dimension (position of the movable plate 6) with a digital switch in advance and the position of the movable plate 6 described above to instruct the servo motor 24 about an appropriate movement amount. When the servomotor 24 operates, the feed screw 25 causes the slide block 23 to move on the rail 26, so that the column 10 connected to the slide block 23 is moved.
Also moves. As a result, the movable plate 6 also follows, and the position of the movable plate 6 can be changed to the designated position.

When the width adjustment is completed, the electric screwdriver 14 is rotated in the forward direction (fastening direction) to tighten the screw 5 to fix the movable plate 6, and the column 10 is retracted by the servomotor 24 to move the frame 22 out of the carry-out operation range. It retracts and releases the positioning and fixing of the frame 22. Finally, the transport roller 15 is rotated to carry the frame 22 out of the apparatus.

A belt conveyor or a chain conveyor may be used instead of the transport roller 15 in the above embodiment. Also,
A fixed plate may be used instead of the fixed prop 17, and the electric screwdriver 14
A reversible motor or an air motor type driver may be used instead of, and a pulse motor may be used instead of the servo motor 24. Further, as a method for fixing the movable plate 6 to the column 10 side, the suction pad 13 is used, but a mechanical clamp method may be used. Further, although the feed screw 25 is used for driving the column 10 back and forth, it may be driven by a toothed belt or a chain.

[Effect of device]

As described above, according to the present invention, the width adjustment, which was conventionally performed manually, is automatically performed by the machine, so that the adjustment can be performed quickly and accurately. There is an effect that labor saving and unmanned operation are possible.
