Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus for pasting barcode labels for identification and the like in a production line for steel pipes and the like.

[Conventional technology]

For example, on a steel pipe manufacturing line, steel pipe 1
In order to accurately track each book, methods such as attaching magnetic marks or paint marks to the surface of each steel pipe, or attaching barcode labels to the surface of the steel pipe have been implemented.

In the latter case, the barcode label generally uses a plastic film with a barcode printed on it attached to the surface of a base material made of magnetic rubber, etc., and then a laminate film attached to that surface. .

Conventionally, barcode labels have been manufactured manually, and they have also been attached to objects such as steel pipes manually.

[Problem to be solved by the invention]

However, this method was extremely inefficient and low in productivity. In addition, it was difficult to bond accurately.

Therefore, the main object of the present invention is to provide a pasting device that can automatically manufacture and pasted barcode labels.

[Means to solve the problem]

The above-mentioned problems are related to a label supply device and a magnetic sheet supply device that separately supply printed barcode labels and magnetic sheets to the bonding position, and a bonding system that bonds the labels and magnetic sheets together. This can be solved by providing a device, a device for taking out the laminated sheet from the bonding position, and a pasting device for receiving the taken out laminated sheet and pasting it on the adherend.

〔Example〕

The present invention will be explained in more detail below with reference to embodiments shown in the drawings.

FIG. 1 is a front view, and FIG. 2 is a side view. In the figure, 1 is a label printer whose details are shown in FIG. That is, the barcode printing paper 2 has a printed label (not shown) intermittently in the longitudinal direction on the mount 2a, and is stacked with an adhesive on the lower surface.
is fed out from the supply reel 3, and before the first conveyor 4 connected to the outlet, only the mount 2a is peeled off from the printed label and wound onto the take-up reel 5. Reference numeral 6 denotes a printing ribbon supply reel, and a bar code corresponding to the adherend, for example, a steel pipe P, is printed on the label of the printing paper 2 during the process of winding it onto a take-up reel 7.
The printed barcode label L ₀ is conveyed by the first conveyor 4 and supplied to the bonding position.

A magnet sheet _L1 made of, for example, magnetic rubber and the laminate sheet 8 are supplied to this bonding position.

A magnetic sheet supply device 10 is provided below the bonding position. This magnetic sheet supply device 10 basically consists of a storage cassette 11.
It consists of a take-out device 12 and a second charging conveyor 13. The storage cassette 11 has, for example, three storage boxes 11A, 11B, and 11C, which are integrated on a base plate 14, and are connected to a motor 15 and a screw shaft 16 along the feeding direction X of the barcode label _L0 . This makes it more mobile. As a result, when one _bundle of magnetic sheets L in one storage box becomes empty, the next storage box is moved below the take-out device 12.

The magnetic sheet _L1 in each storage box 11A to 11C is supported by a push-up lever 17 adjacent to a certain storage box in the Z direction.
The push-up lever 17 is raised by the motor 18 and the screw shaft 19 each time the magnet sheet _L1 is taken out one by one.

The take-out device 12 is mounted on a suitable frame, and is attached via a mounting plate 23 to the belt of a cut-out conveyor 22 that moves in the Z direction by a cut-out motor 21 that rotates a cut-out plate 20 having a cut-out step portion 20a in forward and reverse directions. ing. It is attached via a mounting plate 23. Initially, the cutout step 20a of the cutout plate 20 is positioned behind the rear end of the magnetic sheet _L1 , as shown in FIG. When being sent out in the direction of 13, only the largest magnetic sheet _L1 is caught by the cutting step 20a and sent out to the second conveyor 13. At this time, the uppermost magnetic sheet
In order to ensure that only _L1 is cut out, as shown in FIG. 7, it is suctioned by a suction cup 25 through a hole in the cutting plate 20. In FIG. 7, four position sensors 26 installed around the cutting plate 20 detect when the lever 17 stops when the magnetic sheet to be taken out is pushed up onto the cutting plate 20. This is for detecting timing.

The second conveyor 13 has two belts 24 wound around in parallel, and a bonded receiving plate 31 is provided between them, and a stopper 27 is arranged near the end of the belt. , stop the sent-out magnet sheet _L1 there,
The bonding position is being determined. The second conveyor 24 is stopped by detecting the magnetic sheet _L1 with the sensor 28.

Above the bonding receiving plate 31, as shown in FIG.
3, it is attached to its support shaft 36 so as to be movable along the X direction. This movement is performed by an air cylinder (not shown). A suction motor 35 is mounted on the support 33.
These include a suction header 32, a support body 33, and a support shaft 3.
6 and the motor 35 are movable up and down along the guide 34 by a cylinder 34A or the like.

Further, the suction header 32 is located on the lamination receiving plate 31 and adjacent to the outlet end of the first conveyor 4 and between the laminate supply plate 41 of the laminate sheet 8, which will be described later.

Next, before explaining the bonding, the bonding device 3
Regarding the supply system 40 of the laminate sheet 8 that is supplied from the left side of 0, the laminate is rewound from the supply reel 42 and has laminate labels L ₂ intermittently in the longitudinal direction on the mount 8a having an adhesive on the lower surface. When the sheet 8 goes around the tip of the supply plate 41, it leaves the lamination label L ₂ and the mount 8
Only part a is wound onto the take-up reel 43.

In the apparatus configured in this way, when the printed barcode label _L0 is supplied from the first conveyor 4 to the suction header 32, the suction header 32
moves along the support shaft 34 to near the exit end of the first conveyor 4 and waits, and the suction header 3 with the label L ₀
When the label 2 is fed downward by the first conveyor 4, as shown in FIG.
Aspirate L ₀ . When the label L ₀ is fed out, use the air purge nozzle 3 to watch the tip of the label L ₀ hang down.
The air blown from 7A prevents this. Suction header 3
After confirming that the label L ₀ has been fed out to the correct position on the lower surface of 2, the suction header 32 returns to the correct central position on the laminated receiving plate 31, and then
The suction header 32 is lowered by the elevating cylinder 34A while adsorbing the label _L0 , and is superimposed on the receiving plate 31 and the belt ₂₄ on which the magnetic sheet L1 sent out by the second conveyor 13 is placed. As a result, the printed barcode label _L0 is pasted onto the magnetic sheet _L1 .

When this pasting is completed, the suction header 32 is raised by the lifting cylinder 36, moves to the left, and waits for the supply of the laminate label _L2 . Then,
When the laminate label L ₂ is fed out to the bottom surface of the suction header 32 and this is completed, the suction header 32
After returning to the center position, laminate label 32
is lowered by the lifting cylinder 34A while adsorbing the barcode label L2, and the laminated label _L2 is stuck onto the printed barcode label _L0 that has not been moved. Such a superposition is shown in FIG. 12.

Note that the air purge nozzle 37A prevents the tip of the laminate label _L2 from hanging down as it is fed out. 38A and 38B are stoppers for label _L0 and label _L2 , respectively. In addition, a spring 39 for separating is provided on the lower surface of the suction header 32 so that when the suction header 32 is raised after overlapping each label L ₀ , L ₁ , and L ₂ , the labels are not taken along. ing.

Thus, the laminated label L is taken out from the pasting position by the taking out device 50, as shown in FIG. 11, and is supplied to a pasting device 60, which will be described later.

The take-out device 50 includes a transfer arm 51 provided on the side of the second conveyor 13. Also, in parallel with the second conveyor 13, a third conveyor 5 for feeding is provided.
2 is provided. The transfer arm 51 is attached to the rod of the lifting pick-up cylinder 53,
T-shaped in plan, suction suction cup 5 at the tip
There are 4,54. Further, the rod of the pick-up cylinder 53 is capable of moving up and down as well as rotating 180 degrees around a rigid axis.

Now, the transfer arm 51 rotates above the laminated label L, descends, adsorbs it via the suction cups 54, 54, rises, and then
After turning 180 degrees and positioning on the third conveyor 52,
It descends, releases the suction by the suction cups 54, 54, and transfers the label L onto the third conveyor 52. Before the label L is sent on this third conveyor 52 to a pasting device 60 (described later), the barcode of the label L is read by a barcode reader 55, and a series of processes from issuing the barcode label to pasting the label L are carried out. During processing, if the barcode does not match the issued information or is poorly readable due to mishandling such as dropping, the third conveyor 52 is reversed and the barcode is transferred to the redirect hopper 56 in front. It is paid out and an alarm is issued. Reference numeral 57 is a stopper that can be moved up and down to stop the label L at the reading position.

The label L with good readability is further transferred to the third conveyor 52.
and reaches below the pasting device 60 along the X direction, and stops based on the signal from the sensor 58. As shown in FIG. 15, this stopped label L is pushed up from below by a push-up piece 72 attached to the rod of the cylinder 71, and the other end is pushed up by a roller 73.
The hollow insertion arm 61 that forms part of the hollow insertion arm 61 is brought into contact with the belly of the hollow insertion arm 61 . It is perforated by suction cups 62, 62 in the insertion arm 61 and sucked by negative pressure.

On the other hand, a head 64 having a cushion material such as rubber 63 at the front end is provided in front of the insertion arm 61, and a shaft portion 64a of the head 64 is fitted into the insertion arm 61. The rear end of the head 64 and the front end of the insertion arm 61 are provided with bellows 65 to prevent dust from entering. Also, the fixed flange 64b of the shaft portion 64a of the head 64 and the end plate 61 in the insertion arm 61 are connected to each other.
A repulsion spring 66 is provided between the head 64 and the end of the steel pipe P, and if the head 64 collides with the end of the steel pipe P, the repulsion spring 66 absorbs the collision force and detects the movement of the shaft portion 64a and, as a result, detects the collision using a sensor 67.
It is designed to be detected by

When the insertion arm 61 is inserted into the steel pipe P to a predetermined position by the feed rollers 68, 68 (FIG. 4) of the insertion arm 61, the label L attracted to the insertion arm 61 is stopped by the suction cup 62 and becomes sprayed. It changes (becomes a jet) and is attached to the inner surface of the steel pipe P. When inserting the insertion arm 61, the end of the steel pipe P is detected by the pipe end detection sensor 69A and affixed to a pre-specified position, and during insertion, the air purge nozzle 69B facing the bottom removes dust and water from the inner surface of the steel pipe P. It is designed to be excluded.

After such pasting, the pasting device 60 is pulled out from inside the steel pipe P and holds the next label and steel pipe. if,
If the pasting cannot be done well, for example, the pasting device 6
When the 0 head 64 collides with the steel pipe P, the suction by the suction cup 62 is stopped, the label is returned to the third conveyor 52, and the redirect hopper 7 is placed from the far end.
Collect at 4. At this time, an alarm is issued.

The above operations are repeated in sequence.

In the above example, the laminate sheet is preferable for preventing dust from adhering to it, but is not necessarily essential. Alternatively, the printed barcode label may be laminated before the bonding position after printing.

The label supply device and the magnetic sheet supply device are not limited to the belt conveyor system, but may also include a method of picking up by suction suction, raising by a cylinder rod, moving the cylinder, lowering the cylinder rod, and releasing the suction suction. This example can be understood as it approximates the extraction device 50. Furthermore, if the second conveyor 13 is extended to below the pasting device 60, the second conveyor 13 functions as a take-out device. Furthermore, the pasting device 60 may be of the same type as the take-out device 50. In addition to steel pipes, adherends include steel plates, slabs, rolls,
Alternatively, products other than products produced at steel mills may also be subject to this regulation.

〔Effect of the invention〕

As described above, according to the present invention, barcode labels can be automatically produced, pasted together, and pasted onto objects, which significantly improves efficiency and reduces pasting and pasting defects. benefits are brought about.
