Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label sticking device for printing a label stuck on a long mount and peeling the label and sticking it on a product.

2. Description of the Related Art Generally, in this type of device, a label on which necessary data is printed is peeled off at a peeling part and is fed out with a gluing surface facing down on a substantially horizontal label pedestal, and the upper surface of the label is fed out. Is adsorbed and held by the label adsorbent, transferred to the product surface, and attached to the upper surface thereof. Then, the suction airflow from the lower surface of the label adsorption body is used to adsorb the label issued on the label cradle to the label adsorption body. Since it is not reliable, a push-up member that pushes up the label is provided on the label cradle. This push-up member is either connected to the iron core portion of the solenoid, or the iron core portion itself is used as the push-up member.

Problems to be Solved by the Invention First, there are one push-up member and a plurality of push-up members. One of them is designed to push up near the center of the label, but the size of the label is When it is changed, it cannot be pushed near its center, and its certainty cannot be expected when it is transferred to the label adsorbent.

Further, in the case where a plurality of push-up bodies are used, it is difficult to project all of these push-up bodies horizontally, and a delicate adjustment work is required at the time of assembly.

Means for Solving Problems A label receiving base for receiving a label sent out from a label printer is provided substantially horizontally with a lower surface serving as a gluing surface, and a pad for reciprocating from the upper portion of the label receiving base to a product position is provided. A label adsorbent is provided, and an abutment parallel to the fixed frame is provided below the label receiving base in a substantially horizontal direction. The abutment is supported movably in the vertical direction while being parallel to the fixed frame. A parallel link mechanism is provided, one driving source is connected to the parallel link mechanism, and a plurality of push-up pins protruding from the label receiving base are provided on the abutment.
Further, a collar urged upward by a coil spring is attached to the tops of these push-up pins so as to be vertically movable.

Action The parallel link mechanism supports the abutment in parallel with the fixed frame so that it can move in the vertical direction, and the parallel link mechanism is driven by the drive unit, so that the abutment provided with a plurality of push-up pins is in the parallel state. As it is raised and lowered, all the push-up pins move in parallel during the raising and lowering, and the label can be sent horizontally to the label suction body with respect to the label suction body.
Even labels with different sizes can be securely adsorbed and held, and by attaching a collar biased by a coil spring to the tip of the push-up pin, even if there is a slight inclination with the mating pad It can be pressed.

Embodiment An embodiment of the present invention will be described with reference to the drawings. First, a label printer 2, a mount winder 3, a vacuum pump 4, and a control box 5 are mounted on the installation table 1. A label attaching mechanism 6 is hingedly connected to the front surface of the label printer 2 so as to rotate between a state in which it is located on the front surface and a state in which it is rotated and retracted to the side surface. Since the label sticking mechanism 6 is rotatably hingedly attached in this manner, the front surface of the label printer 2 can be opened, and the internal mechanism thereof can be easily inspected and cleaned.

Then, inside the label printer 2, the label 7
The long-sized mount 8 which is affixed at equal intervals and wound in a roll is stored, and the mount 8 is abruptly bent at the peeling unit 10 via the printing unit 9, and the tension driving unit 11 by a pair of rollers is installed. After that, it is wound around the mount winder 3. Then, the label 7 is peeled off at the peeling section 10, and the label attaching mechanism 12 is provided with the label receiving base 12 so as to hold the label 7.

Although the label attaching mechanism 6 is partially covered with the cover 13, a frame 14 serving as a fixing portion is provided inside the cover 13. Axis to this frame 14
A base 15 of an arm 16 having a bifurcated lower part is rotatably mounted on the shaft 15. A passive pulley 17 around the shaft 15 is fixed to the base of the arm 16. This passive pulley 17 has a belt 20 attached to a drive pulley 19 connected to a motor 18 serving as a drive unit.
Are connected by.

A rotary shaft 21 is rotatably attached to the tip of the arm 16, and a label suction body 23 having a pad 22 is fixedly attached to the end of the rotary shaft 21. A vacuum pump 4 is connected to the label adsorbent 23, and
22 is configured to generate a negative pressure for sucking and holding the label. A first pulley 24 is rotatably attached to the shaft 15, and the first pulley 24 is attached to the rotary shaft 21.
A second pulley 25 having the same diameter as 24 is fixed, and the first pulley 24 and the second pulley 25 are connected by a belt 26.

Next, the first pulley 24 is fixed with a large-diameter passive gear 27, and the passive gear 27 has a drive gear serving as a rotation drive unit.
28 is engaged. A motor 29 is connected to the drive gear 28.

In addition, 30 is a product to which the label 7 is attached.

Next, the label receiving base 12 is provided with a plurality of receiving shafts 32 having a large number of abacus ball-shaped contact rings 31 coaxially and rotatably mounted in parallel. And
Between these receiving shafts 32, a total of nine push-up pins 33, three vertically and three horizontally, are arranged. These push-up pins 33 are respectively attached to the pedestals 34 which are located below the receiving shaft 32 of the label receiving base 12 and which are provided substantially horizontally.

A flange 35 is formed above the push-up pin 33, and a small diameter portion having a screw is formed on the flange 35.
36 are formed. A cup-shaped collar 38, which is urged upward by a coil spring 37, is slidably attached to the small-diameter portion 36. The collar 38 has a washer 39 and a nut.
It is locked by 40 and.

Next, the abutment 34 is attached to the fixed frame 42 via a parallel link mechanism 41. That is, the central portion is the axis 43
By this, the two links 44 are rotatably connected in an X shape,
One end of each of these links 44 is rotatably attached to the fixed frame 42 and the supporting base 34, and the other end is horizontally slidably attached to the fixed frame 42 and the supporting base 34. There is.

A solenoid 45 as one drive source is fixedly provided, and a link 47 rotatably attached to a fixed shaft 46 and two links rotatably attached to both ends of the link 47. The solenoid 45 and the abutment 34 are connected via 48.

In such a structure, the label 7 is placed on the label receiving base 12.
When the label is sent out, a negative pressure is supplied to the pad 22, and the label 7 on the label receiving base 12 is sucked and held by the pad 22. That is, when the pad 22 of the label adsorbent 23 faces the label receiving base 12 in close proximity, the solenoid 45 operates to rotate the link 47 counterclockwise and push up the support 34.
At this time, since the abutment 34 is connected to the fixed frame 42 through the parallel link mechanism 41, the abutment 34 moves in parallel, whereby all the push-up pins 33 attached to the abutment 34 move in parallel. And then evenly protrude from the surface of the label receiving base 12. Therefore, the label 7, which is in contact with the contact ring 31 of the receiving shaft 32 and is received substantially horizontally, is uniformly extruded as a whole and pressed by the pad 22. At this time, the collar 38 is elastically held by the coil spring 37, so
Even if there is a slight inclination between the label 22 and 22, the label 7 is pressed evenly. Further, since the upper edge of the collar 38 is a thin edge, even if it comes into contact with the gluing surface of the label 7, it will not adhere with a strong force. Then, once the negative pressure is applied to the pad 22,
Since the label 7 adsorbed on the label 22 has a strong degree of adsorption on the pad 22 side, the label 7 does not follow even if the support 34 is lowered to lower the push-up pin 33.

Then, the motor 18 is started to rotate the passive pulley 17 via the drive pulley 19 and the belt 20. This passive pulley 17
Since the arm 16 and the arm 16 are integrally attached, the arm 16 rotates together with the passive pulley 17. At this time, the motor 29
If the drive gear 28 is not stopped and the drive gear 28 is maintained in a stopped state, the first pulley 24 is in a fixed state even when the arm 16 rotates, and the first pulley 24 and the second pulley 25 are Have the same diameter, so when the arm 16 rotates, the second pulley 25
Moves according to the position movement of the tip of the arm 16, but does not rotate with respect to absolute coordinates. Therefore, the pad 22 of the label adsorbent 23 always moves downward. As a result of the movement of the pad 22 in this way, the gluing surface of the label 7 held by the pad 22 reaches the upper surface of the product in a horizontal state while facing downward and is pressed and stuck. Then, when the motor 18 rotates in the reverse direction, the pad 22 releases the adsorption of the label 7, the label adsorbent 23 returns, and the same operation is repeated.

Such an operation is performed when the direction of the label 7 held on the label pedestal 12 and the direction of the sticking surface of the product 30 match. Therefore, when the label 7 is to be attached to the side surface of the product 30, the other motor 29 is driven and the drive gear 28 is rotated while the arm 16 is rotating based on the drive of the motor 18. This allows the passive gear 27
Rotates to rotate the first pulley 24. By the rotation of the first pulley 24, the second pulley 25 is also rotated by the same angle via the belt 26, and the label suction body 23 is rotated. Therefore, the orientation of the pad 22 changes. In this case, the rotation angle of the pad 22 matches the rotation angle of the original first pulley 24. Therefore, if the side surface of the product 30 is a vertical surface, the rotation angle of the first pulley 24 driven by the motor 29 may be set to 90 degrees. Further, the rotation timing may be any time until the label 7 faces the product 30.

When the motor 29 is driven in this manner, when the arm 16 returns, the pad 22 is rotated in the opposite direction by the same angle until it faces the label receiving base 12.

EFFECTS OF THE INVENTION As described above according to the present invention, the label receiving base for receiving the label sent out from the label printer is provided substantially horizontally with the lower surface serving as the adhesive surface, and reciprocates from the upper portion of the label receiving base to the product position. A label adsorbent equipped with a pad is provided, and an abutment parallel to the fixed frame is provided below the label receiving base in a substantially horizontal direction, and the abutment can be moved up and down while being parallel to the fixed frame. Is provided with a parallel link mechanism for supporting the parallel link mechanism, one driving source is connected to the parallel link mechanism, and a plurality of push-up pins projecting from the label receiving stand are provided on the abutment. Since the collar urged upward by the coil spring is attached to the top of the pin so that it can move up and down, the parallel link mechanism supports the abutment vertically so that it can move in the vertical direction in parallel with the fixed frame. By driving the parallel link mechanism with the drive unit,
The abutment provided with a plurality of push-up pins moves up and down in a parallel state, and at the time of the up-and-down movement, all the push-up pins move in parallel so that the label can be fed horizontally to the suction surface of the label suction body. It is possible to securely adsorb and hold even labels of different sizes, and by attaching a collar urged by a coil spring to the tip of the push-up pin, the inclination with the mating pad can be slightly adjusted. Also has the effect that it can be pressed evenly.
