Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a drilling device for a plate material such as a glass plate, and in particular, a drilling device for a plate material that is effective when drilling a plurality of holes in two plates. Concerning improvements to equipment.

[Prior Art] Generally, in the case of automobile side window glasses and glass back doors, components such as regulators, hinges, lock strikers, balancers, etc. are installed by drilling holes in the glass plate. This hole is used as a hole for attaching tools.

Conventionally, as a device for drilling holes in this type of glass plate,
A plurality of drill units as drilling tools are installed in advance on the drilling stage corresponding to the drilling positions of the glass plate, and after the glass plate is positioned and fixed on the drilling stage, each drill unit is used to drill the glass plate into the specified position. A device in which a hole is bored is known.

[Problem to be Solved by the Invention 1] By the way, in such a board drilling device, as the number of drilling locations in the board increases, the number of drill units to be installed on the drilling stage increases accordingly. This results in a problem of increasing the size of the device itself.

In addition, when installing the drill unit in the above-mentioned drilling stage, the positional relationship between the drilling target position of the plate material and the drill unit must be set accurately, so conventionally, the drilling target position of the plate material is Although the drill unit installation work has been performed using an accurately displayed reference template, a problem arises in that the drill unit installation work becomes troublesome as the reference template must be manufactured.

Furthermore, if the drilling target positions of the plate material are very close to each other, it will be difficult due to the layout to install the drill unit at a position that corresponds to the adjacent drilling target positions, so it is difficult to perform the drilling work. It becomes necessary to provide a plurality of drilling stages, and the working stage space required for the drilling operation increases accordingly, resulting in a situation that does not meet the demand for space saving.

This invention was made in view of the above-mentioned problems, and effectively prevents the increase in the size of the device itself and the troublesome installation work of the drilling tool, while simultaneously drilling multiple holes in one drilling stage. An object of the present invention is to provide a perforation device for a plate material that can efficiently perform perforation.

[Means for solving the problem] That is, as shown in FIG.
and a tool driving means 2 for moving the drilling tool 1 up and down between a drilling operation position and a standby position on the drilling stage ST;
A movable table 3 having a plate holding portion 3a and movably supporting the plate holding portion 3a in any direction W on a predetermined plane of the drilling stage ST; a table driving means 4 for moving the movable table 3; The table driving means 4 and the tool driving means 2 are sequentially driven according to the drilling information of G, and the plate material holding part 3 of the movable table 3 is driven for each drilling information.
After setting the drilling target position of the plate material G held at position a in correspondence with the position of the target drilling tool 1, the drive controller 5 cooperates with the drive control means 5 to set the target drilling tool 1 in the standby position to the drilling operation position. It is something that has been learned.

In such technical means, a glass plate, a resin plate, a metal plate, etc. can be appropriately selected as the plate material G to be perforated. In addition, as the drilling tool 1, a drill unit, a punch for drilling, etc. may be selected as appropriate depending on the type of the plate material G, and the number of drilling tools 1 may be selected at least according to the type of diameter dimension of the target hole. You only need to place as many as you want. At this time, if the plate material G is a glass plate, the drilling tool 1
It is preferable to use a pair of drill units that are arranged opposite to each other with a glass plate in between.

Further, the tool driving means 2 may be appropriately selected as long as it consists of a lifting means for supporting the drilling tool 1 so as to be able to rise and fall freely, and a drive actuator for driving the lifting means.

Further, as the plate material holding portion 3a of the movable table 3, as long as it can restrain and hold the plate material to such an extent that the plate material G is not displaced by the drilling operation of the drilling tool 1, suction holding means, grasping holding means, etc. may be selected as appropriate. However, it is preferable to use suction holding means for items that are easily damaged, such as glass plates. Further, the holding surface of the plate material holding portion 3a is the plate material G.
When drilling a hole at any location on the periphery of the plate material G when the hole is smaller than one side of the plate material G, from the viewpoint of stably performing the drilling operation with the drilling tool 1, it is necessary to It is preferable to design it so that it can be locally restrained and held by a clamping means.

The movable table 3 may be an X table and a Y table that move linearly in two directions (X and Y directions), as long as it can support the plate holding part 3a in a movable manner along an arbitrary direction W. They may be combined, or may be selected as appropriate, such as by combining an X table and a rotary table.

In this case, the location of the rotary table or Y table is not limited to the top of the X table, but may be located at the end of the X table. In the case where the movable table 3 is configured to collide with a unit that moves the drilling tool 1 up and down, from the viewpoint of ensuring a wide range of drilling possible in the plate material G, it is preferable to combine an X table and a rotary table. However, even in the case of a combination of an X table and a Y table, if the width of the table extending in the direction that hits the unit that moves the drilling tool 1 up and down is narrowed, the area where drilling is not possible in the plate material can be avoided. can be kept extremely narrow.

Furthermore, the table driving means 4 may include a driving actuator such as a servo motor, and a driving force transmitting means such as a ball screw that transmits the driving force from the driving actuator to the movable part of the movable table 3. You may choose as appropriate.

Further, as the drive control means 5, any suitable device including an NC device may be selected as long as it can realize the above-mentioned control function. In this case, the drive control for the tool driving means 2 can be designed as appropriate, but when the drilling tool 1 is a drill unit and the speed is to be increased, the drilling tool 1 is moved from the standby position to the drilling operation position. It is preferable that the drilling operation be performed stably by moving at a high speed and then moving at a low speed when the drilling operation position is reached. Further, drive control for the table driving means 4 may be performed by appropriately selecting the order of drilling in the plate material G according to drilling information such as the perforation position of the plate material G and the diameter of the hole, but the drilling operation may be optimized. It is preferable to select the order of drilling as follows.

In addition, from the viewpoint of making the drilling operation of the drilling tool 1 stable at all times, a polishing means that is movable between the plate arrangement position and the standby position is provided in a part of the movable table 3, and It is preferable to design the drilling tool 1 so that the drilling tool 1 is periodically polished by the polishing means when one drilling operation reaches a predetermined number of times. In this case, a step for controlling the polishing operation of the polishing means may be incorporated as part of the control operation of the drive control means 5.

In addition, with respect to the above-mentioned technical means, if the above-mentioned drilling tool 1 is replaced with another processing tool, it is also possible to develop the device into a device for chamfering, peripheral edge processing, etc. of plate materials.

[Operation] According to the above-mentioned technical means, the plate material G to be perforated is held in a positioned state by the plate material holding part 3a of the movable table 3, while the above-mentioned perforation tool 1 is held in a positioned state before the perforating operation. is set to the standby position.

In this state, the drive control means 5 drives the table drive means 4 for each piece of drilling information to move the movable table 3 appropriately, and moves the drilling target position of the plate material G to the corresponding drilling tool 1.
After setting the corresponding drilling tool 1 to the drilling operation position, the tool driving means 2 is driven to set the corresponding drilling tool 1 to the drilling operation position. Therefore, each drilling target position of the plate material G has a corresponding hole of a predetermined diameter with the drilling tool 1.
The holes are automatically drilled in sequence.

First, the NC device 110 starts the drilling device by turning on a power switch (not shown), and keeps each drive motor 23 of the drill unit 20, 21 constantly rotating. When the central part of the glass plate G, which has been positioned by a positioning device (not shown), is placed on the suction holding part 58 of the movable table 50, the space 61 becomes hermetically sealed, and the negative energy from the vacuum source is removed. Since the air in the space 61 is suctioned by the pressure, the glass plate G is suction-held by the suction-holding section 58 .

In this state, the NC device 110 operates on the glass plate G.
A control signal (xl
, θ1) to the X table 50 and rotary table 55, and move the X table 50 by x1 from the initial position, and rotate the rotary table 55 by angle θ1 from the initial position, thereby setting the drilling target position P1 of the glass plate G. is set as the drill axis position Qa of the corresponding drill unit 20 (14th
(See figure (a)).

Thereafter, as shown in FIG. 15, the NC device 110 drives the driving air cylinder 47 of the clamping means 40 to restrain and hold the glass plate G around the perforation target position 11 with the pair of clampers 41 and 42. After that, when the setting of the drilling target position IPI of the glass plate G is completed, a drilling operation start signal is given to the drive motor 37 of the lifting drive means 30 of the corresponding drill unit 20, and, for example, the corresponding drill unit 20 is started drilling from the standby position. It is moved at high speed to the operation position, and then moved at low speed to the drilling operation position. Then, the drills 22 of the upper and lower drill units 20 drill the target hole P1 of the glass plate G from the front and back surfaces, thereby forming the first hole 120.

Then, the NC device 110 receives a drilling completion signal from the drive motor 37 by the drill unit 20 and sends a return command to the drive motor 37 to return the drill unit 20 to the standby position. A return command is sent to 47 to return the clampers 41 and 42 to the standby position. At this stage, the punching operation for the punching target position P1 on the glass plate G is completed, and upon receiving a signal to that effect, the NC device 110 moves to the next punching process.

At this stage, the NC device 110 sends a control signal (×2.

The position P2 is set to the drill axis position Qa of the corresponding drill unit 20 (see FIG. 14(b)). Thereafter, a drilling operation similar to the first drilling step is performed, and after the second drilling step is completed, a drilling step for the third drilling target position P3 is performed in the same manner.

Thereafter, the NC device 110 sends a control signal (×4.θ4) to specify the fourth drilling target position P4 of the glass plate G.
is sent to the X table 50 and the rotary table 55, the X table 50 is moved to the ×4 position, the rotary table 55 is rotated to the angle θ4 position, and the drilling target position P4 of the glass plate G is set by the drill of the corresponding drill unit 21. Set to axis position Qb (see FIG. 14(C)). Then, as shown in FIG. 15, the NC device 110 uses the pair of clampers 41 and 42 of the clamping means 40 to punch the counter-dye position P.
After the glass plate G around 4 is restrained and held, when the setting of the drilling target position P4 of the glass plate G is completed, a drilling operation start signal is given to the drive motor 37 of the lifting drive means 30 of the corresponding drill unit 21, and the above-mentioned countermeasures are performed. The drill unit 21 is moved from the standby position to the drilling operation position, and the drills 22 of the upper and lower drill units 21 are used to drill the drilling target position P4 of the glass plate G from the front surface to form the fourth hole 120. . After that, the NC device 110
After returning to the standby position, the clamp means 40 is returned to the standby position, and the fourth drilling step is completed. after that,
The drilling process for the third drilling target position P5 is performed in the same manner.

At this stage, the perforation process for - glass plates G is all completed, the movable table 50 returns to the initial position, and the perforated glass plates G are removed from the suction holding section 58.

As is clear from such a series of punching operation steps, according to the glass plate punching apparatus according to this embodiment, as shown in FIG. It is understood that the peripheral area A (indicated by diagonal lines in the figure) other than the outer area is the perforation possible area.

is engaged in. At this time, when the rotary table 55 rotates, the outer cover 92 also tries to rotate following the rotating shaft 56, but due to the engagement between the stopper protrusion 98 and the position restraining member 99, the outer cover 92 is rotated. On the other hand, since the rotary shaft 56 is rotatably supported by the bearing 91, the rotational movement of the rotary shaft 56 is not adversely affected.

Further, the NC device 110 includes a drill unit 20.2.
When the number of drilling operations (in this example, the total number of both) reaches a predetermined number, a polishing operation start signal is sent, and first,

[Effects of the Invention] As described above, according to the plate drilling device according to the present invention, the movable table side that holds the plate is moved as appropriate in accordance with the 1tIII control information from the drive control means, and the plate material is moved to the drilling stage. Since the drilling tool, which is movable up and down, is aligned with the position to be drilled on the plate material, and the drilling operation is performed by the drilling tool, the following basic effects can be obtained.

First, even if there are a large number of holes to be drilled in a plate, it is no longer necessary to install a large number of drilling tools on the drilling stage depending on the number of holes to be drilled. It can be done efficiently.

Second, since the position of the movable table controlled by the drive control means allows the drilling target position of the plate material to be uniquely set to a predetermined position, the position of the drilling tool can be fixedly set in advance. Therefore, it is possible to eliminate the troublesome work of installing the drilling tool, such as using a conventional reference template when installing the drilling tool.

Thirdly, even if the target drilling positions of the plate material are located close to each other, by moving the plate material appropriately, it is possible to perform the drilling operation with the corresponding drilling tool in one drilling stage, and the drilling speed increases accordingly. It is possible to effectively avoid an increase in the drilling work space, such as by increasing the number of stages to a plurality of stages.

Furthermore, according to the plate drilling apparatus according to claim 3, the clamping means locally restrains and holds the plate near the drilling tool position during the drilling operation, so that even if the drilling tool collides with the plate, The plate material does not bend unnecessarily, and the drilling operation can be performed smoothly.

Further, according to the plate perforation device according to any one of claims 4 to 6, the plate can be smoothly moved in any direction. In particular, according to the fourth aspect, since a combination of an X table and a rotary table is used as the movable table, the area occupied by the movable table can be reduced, and even if the device on the drilling tool side Even if the unit is arranged to abut against the end of the X-table, it is possible to set the perforation area of the plate material to substantially the entire area, and the utilization efficiency of the perforation device can be improved accordingly. Furthermore, in the fifth aspect of the present invention, if the device unit on the drilling tool side is arranged so as to abut against the end of the X table or the Y table, the plate material portion facing the table position In particular, according to the sixth aspect of the present invention, the table width itself can be reduced while stably supporting the movable table, which is the movable part of the movable table. A relatively wide perforation area of the plate material can be secured without impairing the stability of the movement of the table.

Furthermore, according to the board drilling apparatus according to claim 7, the drilling tool can be polished periodically, so that the drilling tool can be maintained and the drilling operation by the drilling tool can be maintained in good condition at all times. I can do it.
