Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention attaches a label or barcode to a packaging container for foods, fruits and vegetables, workers, construction hardware, and other sundries. It relates to a sticking machine used for.

[Conventional technology]

Conventionally, this kind of sticking machine sucks labels by intermittently feeding an object to be stuck such as a packaging container horizontally while rotating a pneumatic suction member with a transmission shaft connected and fixed to a drive shaft. It was supposed to be held and sprayed onto the adherend.

[Problems to be solved by the invention]

However, in the conventional sticking machine, since the transmission shaft is simply connected and fixed to the drive shaft, the transmission shaft and the suction member rotate in the same direction along a circular path in accordance with the rotational drive of the drive shaft. To do. Therefore, it is impossible to set the locus drawn by the tip surface of the suction member to the same level as the pasting surface because the adhesive is applied to the back surface of the labels, and it is inevitable that the required interval be set. The label must be attached by relying on a blowing means such as air. When such a spraying means is used, there is a drawback that the label sticking position is displaced or distorted, and reliable sticking is difficult.

The present invention aims to solve the problems of the prior art all at once, and to provide a sticking machine capable of directly pressing and sticking labels while sucking and holding them with a suction member.

[Means for solving problems]

That is, the present invention is a label sticking machine that sticks labels to a sticking target by sticking and holding labels while rotating the suction member 17 that is fixed to the tip of the transmission shaft 14 in an orthogonal manner. The transmission shaft 14 is rotatably connected to an eccentric position of a drive shaft 16 via a connecting member, and a planetary gear 18 is fitted to the rotary transmission shaft 14, and the planetary gear 18 is It is inscribed in a fixed sun gear 19 arranged on the same axis line as the cam gear so that the transmission shaft 14 is revolved along the inner circumference of the fixed sun gear 19 via the planetary gear 18. By rotating itself in the direction opposite to the revolution and at the same period as the revolution, the suction member 17 is rotated up and down to draw an acute-angled substantially oblong elliptical locus, and when it descends sharply. When the label A is adsorbed and it rises sharply, the adsorption label A Those that are configured to occupy dressed bonded by pressing to the pasting target kimono B.

[Work]

By the rotational drive of the drive shaft 16, the transmission shaft 14 revolves along the inner circumference of the sun gear 19 at a constant pitch via the planetary gear 18, while rotating in the opposite direction of the revolution and at the same cycle as the revolution. Then, as shown by the T-shaped mark in FIG. 1, the suction member 17 is actuated by vertically drawing a locus of a substantially oblate elliptic shape with an acute angle, and at the time of the acute descending, the label A is adsorbed, and At the point when the suction label A rises sharply, the suction label A is pressed against the back surface of the adherend B to ensure the sticking.

Is moved back and forth by a lever 10 via a cam mechanism 9, and the cam shaft of the cam mechanism 9 is coaxial with the cam shaft of the cam mechanism 6 to operate in conjunction with the take-out device 4. It is supposed to be. Reference numeral 11 denotes a pair of endless drive chains which are connected to the feeding device 8 and are disposed on the traveling and guide rail 2 and which can be driven intermittently. 12 is a hook attached to each endless drive chain 11 at a predetermined interval. A stop piece, 13 is the above-mentioned U-shaped support plate which is arranged horizontally at a level slightly higher than the traveling / guide rail 2 so as to face the rear end direction from the central portion thereof, and 14 is the supporting plate 13 and the traveling / guide. The transmission shaft is disposed below the rail 2 and is arranged in a three-dimensional cross-shape. The transmission shaft 14 is rotatably connected to an eccentric position of a drive shaft 16 via a flange 15. 17 is the transmission shaft 14
Pneumatic suction member mounted orthogonal to the tip of
Reference numeral 18 denotes a planetary gear fitted in substantially the center of the transmission shaft 14,
Is a fixed sun gear consisting of an internal gear that is inscribed in the planetary gear 18 so that the planet gears 18 can freely fit, and the center of the sun gear 19 is supposed to be located on an extension of the axis of the drive shaft 16. .
The uppermost portion of the locus drawn by the tip of the suction member 17 is positioned so as to slightly project to approximately the center of the traveling / guide rail 2. Reference numeral 20 denotes a label support table arranged so as to be positioned at the bottom of the locus drawn by the tip of the suction member 17, and A denotes a bar code or other label attached to roll-shaped release paper at predetermined intervals. The label A guide rollers 21 are sequentially and intermittently fed onto the support base 20. In addition, B indicates an adherend such as a packaging container.

Next, the operation of the sticking machine according to the present invention will be described.

First, the adherend B such as a container for egg packaging is placed in the accommodation unit 3 and accommodated upward. After that, the take-out device 4 is operated to raise the suction portion 5, and the lower surface of the adherend B at the lowermost end is contacted and sucked. When the suction is completed, the suction unit 5 is moved down again, and the suction is released when the lower surface of the adherend B reaches the traveling surface of the traveling / guide rail 2, and the adherend B is placed on the traveling surface. Then, the delivery device 8 operates to deliver the adherend B along the traveling and guide rail 2 and stop it at the dead point position. Then, the pair of endless drive chains 11 are driven, and the hooking pieces 12 are hooked on the adherend 2 to transfer the adherend B again toward the rear of the traveling / guide rail 2. The pair of endless drive chains 11 stops driving at the time when the label sticking point of the sticking object B is located at the uppermost end of the trajectory drawn by the tip of the suction member 17. On the other hand, the drive shaft 16 is driven to rotate in conjunction with the drive of the endless drive chain 11. Then, as indicated by the T-shaped mark in FIG. 1, the transmission shaft 14 revolves along the inner circumference of the sun gear 19 at a constant pitch through the planetary gear 18, in the opposite direction of the revolution, and at the same time as the revolution cycle. Rotate in the same cycle. At this time, the suction member 17 mounted orthogonally to the transmission shaft 14 gradually descends by drawing a locus of a substantially oblong ellipse with an acute angle due to the revolution and rotation of the transmission shaft 14, and is supported at the time when it descends sharply. Adsorb the label A on the table 20. And again the transmission shaft
The suction label A is pressed against the sticking surface of the sticking object B at the time when it rises along with the revolution and rotation of 14 and rises sharply. At this time, since the upper surface of the adherend B is supported by the support plate 13, it does not move by being pressed by the suction member 17. When the sticking of the label A is completed, the adsorbing member 17 again descends in a substantially oblong elliptical locus. Adsorption member 17
The pair of endless drive chains 11 starts to drive again in association with the downward movement of the label A, and the adherend B to which the label A has been attached is transferred to the rear side along the traveling / guide rail 2.

Similarly, the take-out device 4, the sending-out device 8, the pair of endless drive chains 11, and the drive shaft 16 are operated in association with each other to take out, send out, transfer, attach the label A, and transfer the adherend B. Automatically and continuously.

〔The invention's effect〕

Since the present invention is configured as described above, the planetary gear 18
While revolving the transmission shaft 14 along the inner circumference of the fixed sun gear 19 in the direction opposite to the revolving shaft, and further rotating at the same cycle as the revolving cycle, the adsorbing member 17 has a vertically sharp angle. Not only can the suction operation of the label A be surely performed at the time of the acute downward movement, but the suction operation of the label A at the time of the acute elevation can be performed. The sticking surface of the sticking object B can be directly pressed and stuck. Therefore,
This invention sets the locus drawn by the tip end surface of the suction member to the same level as the pasting surface because the transmission shaft and the suction member rotate in a same circular path in the same direction as the drive shaft rotates. In comparison with a conventional sticking machine that cannot necessarily be sprayed with a spraying means, the label A can be directly sucked and held by the suction member 17 without using a spraying means. At the same time, it can be pressed and stuck to the adherend B, and there is no possibility that the sticking position of the label A will be displaced or distorted, and the sticking work of the ordinary label A is surely performed. It is something that can be done.
