Following is a detailed explanation given with reference to the drawing.
A spirally wound body 2 of the labels (hereinafter referred to as the body of the labels) has been cut to a certain measurement and adhesive N has been applied to the rear side thereof and pasted continuously onto a strip-shaped paper base 1. The body 2 is loaded in the device as shown in FIG. 2. When a grip 3 fixed in the lower center of the device, is clamped into closed position, rubber printing stamp 32 imprints the label 5 with necessary figures, and when the grip 3 is released, the label 5 thus imprinted is separated completely from the paper base 1 and is delivered to the region of delivery guide 34 and the label applying device W.
Since, adhesive N has been applied to the rear side of the label Mthe surface in contact with the paper base 1when the rear side of the label 5 delivered to the region of the delivery guide 34 and the label applying device W is pressed against the surface of an article, the label is pressed into adhesive contact with the surface of the article. The repetition of this operation makes it possible to carry out imprinting of the labels with figures such as prices, marks or characters continuously, separating the labels 5 from the strip-shaped paper base 1 and pressing the separated labels 5 onto the surface of an article immediately and efficiently.
In operating this device, to expose the place in which the body 2 of the label is to be loaded, a button 7 is pulled in the direction of arrow a (FIG. 3), to separate the tip end k from the connecting part of the device whereupon the cover 8 can be turned in the direction of arrow b about a fulcrum 9.
Then, the body 2 of the label is loaded in the frame 10, one end of the body 2 of the label is pulled out and set as shown in chain lines in FIG. 2. When the button 30 is moved in the direction of arrow g at this time, the lower lid 11 is opened in the direction of arrow c by pivoting about axle 12 to make it easy to thread the end of the body 2.
As shown in FIG. 1 and FIG. 2, when a dial 16 with a combination of suitable numbers is turned, a loop Y of the rubber stamp belt engaged with a rubber roller fixed to the dial 16 rotates to change the combination of the array of the rubber stamps.
In more detail, the loop Y of the rubber stamp belt carries rubber stamps 32 for printing figures, and indexing members 31 arranged symmetrically so that when the stamp 32 are in bottom-most printing position, the corresponding indexing members will appear at the topmost position.
Furthermore, the surfaces of the members 31 are located at a height so that they can not touch the stamp pad 20. The positioning of the rubber stamp 32 for imprinting figures can be realized by arranging the indexing members 31 below a window 17 by turning the dial 16 while looking through the window 17. The frame 19 for the loop of the rubber stamp belt is fixed at one end of the grip 3 through frame 18, and when the grip 3 is closed and rotates in the direction arrow 1', the frame 19 for the rubber stamp belt turns in the direction of arrow 11 about axle 12. Consequently, the closing of the grip 3 turns the loop Y of the rubber stamp in the direction of arrow 11 and the rubber stamps 32 come into contact with the surface of the label to perform a printing operation thereon.
When the frame 19 for the loop of the rubber stamp belt start turning as a result of the closing of the grip 3, the rubber stamp pad 20 moves in the direction of arrow n so that it will not interfere with the movement of the loop Y for the rubber stamp belt. When the grip 3 is released, the grip 3 returns to its original position by the action of a tension spring 21, at which time the frame 19 of the loop for the rubber stamp belt moves in a direction opposite arrow h to return to it original position.
Furthermore, the stamp pad 20 also returns to its original position below the loop for the rubber stamp belt to apply ink to the rubber stamps 32 for printing. Further when the frame 18, assembled with the grip 3, turns in the direction of arrow h as a result of closing said grip 3, a force which was applied to the part A of the label stopper 35 is eliminated and said label stopper 35 turns in counter-clockwise direction around axle 37 by the action of the coil spring 36 until it is stopped by the part B of the label stopper 35 which comes in contact with the lower end of claw case 38, and the resulting release of the part B of the label stopper 35 from the frame strut 39 sets the label N free.
When the grip 3 is clamped, imprinting is performed, and when the grip 3 is released, the label is advanced by the action of the one direction clutch fixed in the delivery roller 15. At this time, since the part B of the label stopper 35 and the frame strut 39 are apart from each other, the label M is advanced smoothly. When the delivery of one label, label M for instance, is completed, the frame 18 comes into contact with the part A of the label stopper 35 and, at the same time, the part B of the label stopper 35 presses the label M on the frame strut 39. The holding of the grip 3 until it comes to a stop in the direction of an arrow h performs the imprinting of the label with figures such as prices and marks or characters, and when the grip 3 is released after the completion of the imprinting operation, the grip 3 returns to its original position by the action of the tension spring 21. At this time, the delivery roller 15 revolves by the action of the one-direction clutch fixed in the delivery roller 15 to advance, outside the device, the strip-shaped paper base 1 held by pressure between the delivery roller 15 and an auxiliary roller 22. The length of the strip-shaped paper base 1 advanced outside the device for the applicaton of one label is equal to the number of rotations of the perimeter of the delivery roller 15 which is also equal to the length of one label. As shown in FIG. 2, the body of the labels is loaded inside the device, and when the grip 3 returns to its original position, the paper base 1 is bent at the tip end of the rubber stamp carrier 13 and drawn outside the device. At this time, the label 5 and part of the subsequent label 6 (FIG. 4) are separated from the paper base 1, and the label 5, as shown in FIG. 7, is delivered between the label applying device W and the delivery guide 34. The delivery guide 34 is mounted on the lower cover 11 and has the shape of a channel for receiving the label 5.
Since the label 5 is delivered in this manner, the label 5, when pasted onto an article by the label applying device W, receives merely the force to be pasted onto the article applied by the label applying device W. However, in the conventional device for the same purpose,
when the label is intended to be pasted onto an article, the rear end of the label is still adhered to the paper base even if the tip end of the label had been delivered to the lower side of the adhesive roller, and thus the rear end of the label had been required to withstand a force to be separated from the paper base.
From this, the force thus applied by the label to be separated to the paper base pulls the ground paper in the direction of the force on the label, resulting in erroneously moving the position of the following labels. As a result, when the grip was clamped to imprint the label imprinting was unable to be performed at the desired place on the label, resulting in non-uniform imprinting of the iabels.
According to the present invention, the label 5 to be immediately pasted and part of the following label 6 are separated completely from the paper base 1, which makes the pasting of the label 5 onto an article easy and-at the same time does not cause the erroneous printing on the following label 6 as no pulling force is applied to said following label 6.
The label applying device W facilitates the pasting of the label 5 delivered 'betweenthe delivery guide 34 and the label applying device W onto an article.
The label applying device W is mounted between side plates 40 and 41, in a manner to be explained as follows with reference to FIG. 7 and FIG. 8. An axle 42 extends between the side plates 40 and 41 and rotatably supports a wheel 43 which possesses several grooves around its perimeter. At both ends of the grooved wheel 43, as shown in FIG. 8 and FIG. 9 are mounted two frames 44 possessing arc-shaped projections 53. Springs 47 are fixed between the outside of the frames 44 and the side plates 40 and 41. One end of each spring 47 is connected with a pin fixed to the respective side plate and the other end is connected with the arc-shaped projection 53 of the frame 44 to urge the frame 44 in the counterclockwise direction at all times. An axle 48 is fixed at the tip end of the frame 44 so that it may swing together with said frame 44 around the axle 42. A wheel 49 is rotatably mounted on axle 48 and possesses several grooves along its perimeter which are symmetrical with the grooves in wheel 43.
Flexible belts 50 are fixed in the grooves of the two grooved wheels 43 and 49. When the tip ends of the flexible belts 50 of the label applying device W come into contact with an article, the label applying device W rotates in the direction of arrow p, against the forces of the spring 47, about axle 42 as a fulcrum. As a result, when the label applying device W comes into contact with an article, any impact is eased by the force of the spring 47 and any possible damage of the device can be prevented. When the label applying device W is removed from the article, it returns to its original position by the action of the spring 47.
The belts 50 are placed in the grooves of the two grooved wheels 43 and 49, and since these two grooved wheels 43 and 49 are close to each other, the belts 50 produce a comparatively large force to resist the bending force. As a result, the belts are curved outwardly. After the label 5 is imprinted, it is delivered between the label applying device W and the delivery guide 34 and pasted onto an article by the label applying device W.
When the label 5 is pasted onto the article by the label applying device W, label 5 is pressed and pasted onto the article through the belt 50 in the region of the grooved wheel 43.
In pressing and pasting the label 5, the label applying device W operate as follows.
The label 5 is brought into contact with the article and pasted at the point at which an are, formed by the belt 50 bending along with the grooves of the grooved wheel 43, and the label 5 come into contact with each other. If the distance in which the label 5 is delivered by the roller 15 is too long, the point at which the arc formed by the belt 50 and the label 5 come in contact moves backward, and, as a result, the pressing force produced by the arc of the belt 50 is applied merely to the latter half of the label.
However, the grooved wheel 49 supporting flexible belts 50 i also fixed to the tip and of the label applying device W, and the belts 50 press against any part of the label remaining unpasted.
Consequently, the entire surface of the label 5 can be completely pressed down even if the distance in which the label 5 is delivered varies as a function of the delivery roller 15.
In the conventional devices of this sort, a pressing roller formed by only a single roller had been in use, and this pressing roller was able to apply pressing force merely to the area of the label behind the point of contact with the perimeter of said roller. Consequently, the front end of the label remained unpressed and unpasted. The label applying device W of this invention removes this drawback and has made pressure pasting of the label throughout its entire area possible as described hereinbefore.
Moreover, since the label applying device W rotates about the axle 42 as a fulcrum, the label 5 can be pasted upon an article completely even if the device and the article come into contact in an angle of broad range when pasting the label 5 to the article.
In the conventional device of this sort, however, the device had to be put into contact with the article at a fixed angle in pasting the label to the article since the position of the pressing roller had been fixed. The frame 44 mounted on the stable axle 42 in the label applying device W is capable of rotating around the axle 42 and since this frame 44 is fixed in such a manner as it may swing together with the axle 48 of the grooved wheel 49, the label 5 can be pasted completely and easily on a fiat surface as indicated in FIG. 11. Further in the label applying device W, as the belts 50 are placed in the grooves of wheels 43 and 49 which are close to each other, the belts 50 produce a relatively large force resisting bending. For this reason, the belts 50 are fixed in an outwardly curved state between the grooved wheels 43 and 49, and thus, as illustrated in FIG. 12, these belts 50 change their form in accordance with the shape of the article even if it has a curved surface, making it possible to paste the label 5 onto the curved surface as shown in FIG. 12. The belts 50 also change their shape to accommodate the curved surface illustrated in FIG. 13 for the same reason, and thus it is possible to paste the label 5 onto such a surface.
In the conventional device of this sort, when an attempt was made to paste the label onto an article possessing such a curved surface as illustrated in FIG. 12 and FIG. 13, the edge of the label remained unpasted since the pressing roller was fixed and was capable of little change in its shape.
However, according the the preferred from of the present invention, these drawbacks have been completely removed, making it possible to apply the entire label onto a curved surface.
In another form of the present invention, as illustrated in FIG. 14 and FIG. 16, an auxiliary roller 54 may be fixed to a receiving frame 55 behind the label applying device W, and this auxiliary roll 54 prevents the label from falling off and at the same time makes it easy for the label 5 free from the paper base to be separated from the following label 6.
Element 56 in the drawing is a shock absorbing spring. As delineated hereinbefore, the label applying device absorbs the shock that occurs at the time of pasting the label to prevent any possible damage of the machine by the shock absorbing action at the tip end of the support-- ing axle of the device. Consequently, the article to which the label is pasted will not be damaged or deformed, which is of importance When the article is fragile.
