Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for pasting a cushioning material such as a sponge on a panel, etc., and is capable of automatic pasting in line work, and can be combined with an index mechanism or
By combining one pasting mechanism with a plurality of supply/separation mechanisms, an apparatus is provided that can pasted cushioning materials of different lengths at different positions at one station.

The automatic cushioning material pasting device of the present invention can be applied, for example, to a device that automatically pastes sponges to mask openings in escutcheon panels for the purpose of preventing chattering noise in escutcheon panels and preventing coin insertion. It is something that can be done.

Conventionally, for this purpose, only a sponge sheet (a 5-6 mm thick sponge coated with an adhesive material and adhered to a backing paper) was cut into strips of a certain width and then cut by hand. The work efficiency was extremely poor because each strip was peeled off from the mount one by one and pasted onto the mask opening of the escutcheon panel of the television.

Therefore, the present invention provides a device that realizes such automatic pasting of sponges and the like.

EMBODIMENT OF THE INVENTION Hereinafter, the present invention will be described in detail with reference to the drawings showing one embodiment thereof.

The device of this embodiment mainly consists of the following five parts. The names and functions are shown below.

First, the sponge take-out mechanism 1 is provided one on each side, and feeds the sponge sheet 6 wound into a roll to the sponge cutting mechanism 2 at a constant rate.

A sponge cutting mechanism 2 is also provided at one location on each side, and cuts only the sponge into a constant width without cutting the mount 8 of the sent sponge sheet 6.

Sponge transfer mechanisms 3 are also provided, one each on the left and right, to transfer the cut sponge 7 to the application chuck lowering position (sponge receiving position).

The sponge pasting mechanism 4 curves and pastes the sponge in accordance with the curvature of the mask opening 10 of the escutcheon panel 9. Then, the index table section 5 positions the conveyor pallet 11 on which the escutcheon panel 9 is placed, lifts it up, and turns it 1/4 turn at a time to change the position at which the sponge is pasted.

Each part will be specifically explained below.

FIG. 2 shows the sponge take-out mechanism 1 viewed from the side.

A sponge sheet 6, in which a sponge 7 serving as a cushioning material is adhesively bonded to a mount 8 having a weak adhesive force with an adhesive adhered to one side thereof, is supplied from a supply roller 12, and is moved to a motor roller 1 according to the path of an arrow.
3 and rollers 14 to the sponge cutting mechanism port. When the sponge 7 is consumed by the sponge cutting mechanism 2, the sponge sheet 6 pushes the limit switch 15. When the limit switch 15 is turned on, the motor roller 13 is driven, and the sponge sheet 6 is fed by the roller 14.

The sponge cutting device 2 includes a metering feed mechanism 16 and a cutting mechanism 17.

The quantitative feeding mechanism 16 is a mechanism for feeding the sponge sheet 6 by a fixed size. FIG. 3 shows a schematic diagram of the quantitative feeding mechanism 16. The sponge sheet 6 fed from the sponge take-out mechanism 1 passes between cast nylon rollers 18 and then passes through the feed roller 19.
is set above. The drive motor 20 and photo sensor 21 move the main sprocket 22 to 1.
When rotated, the slave sprocket is rotated via the belt 23, and the feed roller (with needles) 19 moves the sponge sheet on the sponge guide plate 24 due to the tooth ratio and the gear head connected to the slave sprocket. 6 to a certain size (5
mm). When feeding the sponge sheet 6 and during transfer, that is, until the cut sponge 7 is separated from the mount 8 by the transfer mechanism 3, the pressure roller 26 is lowered by the cylinder 25 and the sponge sheet is moved between it and the feed roller 19. 6 is strongly pinched to increase the feeding accuracy of the sponge sheet 6.

Mount 8 after the sponge 7 has been separated and transferred
is sent to the discharge port 29 with a certain tension by rollers 27 and 28.

Next, the cutting mechanism 17 will be explained. This mechanism 17 cuts only the sponge 7 of the band-shaped sponge sheet 6 on which the mount 8 is attached to a certain length dimension, and cuts it into a substantially rod shape. Do not cut mount 8. FIG. 4 shows a schematic diagram of the cutting mechanism 7. FIG. 4 shows that while the slider 30 is moving in the direction of A, the sponge sheet 6 is cut with the cutter 31.
Of these, sponge 7 is being cut. The drive is a drive using a chain 33 by a motor 32.

As the slider 30 moves in the direction of A,
Roller 3 coupled to cutter holder 34
5 rides on the holder fitting 36. Then, the cutter 31 touches the sponge guide plate 37.
At the same time, the cam 38 fixed coaxially with the cutter holder 34 rotates, and the arm 39
hook the pin. Here, cutter holder 3
4 is in a rising position. Then, the magnetic sensor 40 senses the magnet 41 attached to the slider 30, stops the movement of the slider 30, and waits. After that, when the start signal is input,
The motor 32 rotates in reverse to move the slider 30 in the direction B. At this time, the cutter 31 remains in the upper position. When the roller 35 of the arm 39 hits the arm fitting 42, the pin of the arm 39 is disengaged from the cam 39 and the roller 35 falls into the concave inclined portion 43 of the arm fitting 42.

There, the magnetic sensor 44 reacts to the magnet 41 of the slider 30. As a result, the motor 32 rotates in reverse again to move the slider 30 in the direction A. At the same time, the rollers 35 are
The cutter 31 is smoothly guided onto the sponge guide plate 37 by descending along the slope 43 of No. 2. By moving the slider 30 in the direction A, the sponge 7 is cut into a bar shape of a constant size, and the cutter 31 is raised at 36 per holder and waits until the next start signal is received.

Next, the sponge transfer mechanism 3 will be explained with reference to FIG.

The moving mechanism 3 transfers the sponges 7 cut at regular intervals by the above-mentioned sponge cutting mechanism 2 from the mount 8 to the side train 45.
runs in the lateral direction (perpendicular to the plane of the paper) and performs an operation to carry the sponge 7 to the delivery position with the pasting mechanism 4.

The sponge 7 cut into a constant width by the sponge cutting mechanism 2 is sent onto the sponge guide plate 46. Then, the entire chuck part is lowered by the cylinder 47, and the height chuck (with needle) 4
8 hits the sponge 7 to be transferred, and at the same time, the presser roller 49 comes off and the position regulating plate 50 escapes in the direction A.

Then, the sponge presser 51 presses the sponge 7 one position before the sponge 7 to be transferred.

Next, a side chuck (with a needle) 53 is moved in the f direction by the cylinder 52 to pierce the sponge 7 from the side. In this state, the chuck portion is raised by the cylinder 47 (in the U direction), the position regulating plate 51 is returned, and the chucked sponge 7 is adjusted. Then, the sponge 7 is moved to B by the cylinder 54.
The sponge 7 is transferred to the side train 45 and lowered by the cylinder 47 (in the D direction). Further, the side chuck 53 opens in the direction b, and the chuck portion returns to its original state by both cylinders 47 and 54.

Side train 45 receiving sponge 7
runs on the LM track 55 and carries the sponge 7 to the sponge delivery position with the pasting mechanism 4.

Next, FIG. 6 shows the sponge sticking mechanism 4.

The sponge pasting mechanism 4 receives the sponge 7 from the side train 45 and pastes the sponge 7 into the mask opening 10 of the escutcheon panel 9. On the side train 45, a long sponge 7 cut into a rod shape is placed in a direction perpendicular to the plane of the paper and sent, and a plurality of chucks 56 arranged in a direction perpendicular to the plane of the paper are in an open state. I'm waiting. Then, the pasting block 58 is lowered by the cylinder 57, and the limit switch 59 is
Make an intermediate stop at the position where it hits. At this time, the chuck 56 is stopped directly above the side train 45. Then, close the chuck 56 and use the sponge 7.
Grab at multiple places. Next, the pasting block 58 is raised by the cylinder 57, and the pulse motor 5
9. The slider 61 is moved to the pasting position by the ball screw 60. Then, the pasting block 58 is lowered by the cylinder 57 and the sponge 7 is pasted into the mask opening 10 of the escutcheon panel 9. At this time, the cylinder 57 descends to the bottom dead center, and the sponge retainer 68 shown in FIG.
The sponge 7 is pressed down with a constant force to ensure the attachment of the sponge 7.

Then, open the chuck 56 and release the sponge 7.

Here, the sponge pasting position of the mask opening 10 of the escutcheon panel 9 where the sponge 7 is to be pasted is a curved surface with a large radius, and when pasting the sponge 7, the pasting is done according to the curved surface. There must be. A mechanism for this purpose is shown in FIG. That is, a positioning block 62 and a fixing block 6 are attached to each of a plurality of pasting blocks 58 arranged in a direction perpendicular to the paper surface.
3 is individually adjusted using adjustment bolts 64. Then, at the time of pasting, the adjustment bolt 64 and the fixing block 63 are pressed by the force of the spring 65 and come into contact with each other, so that each pasting block 58 can have its own unique position. Similarly, by adjusting the positions of all other blocks, the curve of the mask opening 10 can be approximated. Even with this arrangement, when receiving the sponge 7, the block 6 is placed on the roller 66.
7 hit, chuck 56 on each chuck block
The eyes line up in a straight line and the sponge 7 can be chucked.

Finally, the index table section 5 will be explained with reference to FIGS. 8 and 9. The index table section 5 is installed below the conveyor 70.

After confirming that the pallet 11 is in the specified position by a limit switch (not shown) on the conveyor 70, the index table 72 is raised by the cylinder 71. By this operation, the positioning pins 73 of the index table 72 are inserted into the positioning holes of the pallet 11, and at the same time, the pallet 11 is lifted higher than the conveyor 70. At this time, the positioning state is confirmed using the limit switch 74.

In this state, after the first sponge 7 is pasted by the sponge pasting mechanism 4 as described above, the positioning pin 77 inserted into the large gear 76 is pulled out by the cylinder 75 and released. Then, the motor 78 rotates the small gear 79 once. As a result, the large gear 76, which is the follower gear, rotates by 90 degrees,
At that position, the positioning pin 77 is inserted again and fixed. The above cycle is repeated four times, and after confirming that the four sponges 7 have been pasted to the four corners of the mask opening 10, the index table 72 is lowered by the cylinder 71 and conveyed by the conveyor 70.

As described above, according to the present invention, it is possible to automatically cut a cushioning material such as a sponge into a certain size and paste it onto a curved surface such as a mask surface of an escutcheon panel just by supplying the material. be.
