Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a printed label pasting machine that is capable of pasting a label on a product and printing on the label.

(Prior Art) Conventionally, in a labeling machine that feeds out a tape by a feeding mechanism operated by opening and closing a handle, peels off a label adhered to the tape, and then sticks the label on an object. , a stopper movable within the stroke of the feeding mechanism is provided in order to regulate the tape feeding length by the feeding mechanism;
The stopper is positioned and fixed with a screw or the like to adjust the tape feeding length. In addition, with conventional label pasting machines, printing is performed when the handle is closed.
When the handle opens and returns, the tape is fed out and the label is peeled off and affixed to the object.

(Problems to be Solved by the Invention) In the above-mentioned conventional label pasting machine, positioning and fixing is done manually using screws, etc., so delicate positioning of the stopper is difficult to adjust, and the handle is not easily adjusted due to the biasing force of the spring. In the opening and return operation, especially when the tape is unrolled and the label is peeled off, and if the label is long, if you loosen your grip on the handle and close it, the long label will be unrolled all at once, peeled off from the tape, and hang down. Therefore, it has the disadvantage that it cannot be applied well, but it should be able to be applied successfully if you relax your hand and move the applicator itself by pulling it toward you to apply the label that is peeled off from the tape to the object. However, there is a problem in that it is actually very difficult to apply the adhesive successfully while relaxing the strength of the hand and moving the applicator itself.

In view of the above-mentioned drawbacks of the conventional technology, the present invention allows the length of the tape to be automatically adjusted according to the adhesion pitch of the label without manual intervention, does not require delicate positioning adjustments, and is equipped with a printed body. The object of the present invention is to provide a very convenient labeling machine that can print, feed out a tape, and peel off a label simply by closing the handle.

(Means for Solving the Problems) In order to achieve the above object, the present invention dispenses a tape by a feeding mechanism that is actuated by the operation of a handle and is equipped with a sliding piece for tape feeding. After the label has been peeled off, in a label sticking machine that affixes the label to an object, the printed body attached to the printing lever slides back and forth in conjunction with the operation of the handle that opens and closes, and when the handle is closed. a cam plate that engages with the printing lever to bring the printing body into contact with the tape and then separates it; a claw mounting member whose tip receives a biasing force in a direction that presses the tape and is swingable; and the claw. When the handle, which is swingably attached to the tip of the mounting member, is closed, the tip comes into contact with the tape due to the biasing force and engages with the tip of the label to be peeled next from the tape, causing an angular displacement. and a sensing claw that angularly displaces the claw attachment member in conjunction with the angular displacement, and a sensing claw that angularly displaces the claw attachment member in conjunction with the angular displacement and determines the length of the tape fed out by the feeding mechanism. an adjustment stop lever that stops the movement of the feeding mechanism to automatically adjust and match the label; and an engagement release member that disengages the sensing claw from the label tip in conjunction with the returning movement of the handle. The present invention is characterized in that printing on the label and peeling off the label from the tape by feeding out the tape are performed only when the handle is closed.

(Function) The label sticking machine according to the present invention is operated by opening and closing the handle, feeds out the tape by the tape feeding mechanism, peels off the label adhered to the tape, and then sticks the label on the object. The printing body attached to the printing lever and the cam plate slide back and forth in conjunction with the operation of the handle to engage the printing lever and bring the printing body attached to the printing lever into contact with the tape. Immediately after printing, the label is separated, and printing with this printed body and feeding out the tape to peel the label from the tape are performed only when the handle is closed. In addition, when the label pasting machine unwinds the tape, the sensing claw, which is swingably attached to the tip of the swingable claw attachment member, engages with the tip of the label adhered to the tape, allowing the tape to be restored. , the claw attachment member is angularly displaced in conjunction with the angular displacement, the adjustment stop lever is angularly displaced in conjunction with the angular displacement of the claw attachment member, and the tape is fed out by the tape feeding mechanism operation. The length matches the adhesion pitch of the label, and the positioning and stopping are automatically performed, and the engagement release member automatically releases the engagement of the sensing claw with the label tip in conjunction with the returning movement of the handle. .

Slide piece 22 at a predetermined position that matches the pitch.
And the feed claw 18 is positioned and stopped. label L
remains on the pressing piece 7b of the pressing roll 7 with the adhesive surface facing outward. This fixed label L can be pressed onto an object and affixed at a predetermined position. After that, when you release your hand from the handle 4, the handle 4 returns to the closed state due to the action of the tension spring 8, and at this time, the adjusting pawl 43 is inserted into the toothed portion 41 of the sawtooth plate 41.
contacting the slope of the segment 4a and moving away from the receiving part 27c, the pressing piece 4b of the segment 4a comes into contact with the bar-like protrusion 42c within the last 3 degrees of this return stroke,
The engagement release member 42 is angularly displaced and the roller 42e on the tip 42b side of the engagement release member 42 presses the adjustment stop lever 39, whereby the sensing claw 29 moves in the direction away from the guide surface 6b and the tape T. death,
The tip of the tension spring 37 is separated from the tip of label _L1 .
The cam plate 50 is restored to its original position by the action of , and the cam plate 50 performs a backward stroke due to the angular displacement operation of the rod-shaped projection 15e due to the reverse rotation of the gear 15 and the movement of the intermediate link 53, and the return piece 51 hits the lowering operation rod 57. The tape feed lever 17 returns to the predetermined original position shown in FIG. 3a, and at the same time, the base portion 17b of the tape feed lever 17 is pushed by the groove edge 15f of the gear 15, and returns to the original position shown in FIG. 4a, preparing for the next operation.

In this label pasting machine, the tape holding member 3, the peeling guide member 6, and the swinging door body 13 are cantilevered, and only one end side is supported. It can easily accommodate tapes of a wide range of widths, from long lengths to wide tapes that protrude.

Note that the label sticking machine according to the present invention is not limited to the above-mentioned embodiments, and may be of a type that uses a pair of rollers as a feeding mechanism. A circular saw-shaped disc having a circular saw shape is mounted on the axis of the roller, and an adjusting claw 43 is provided on the adjustment stop lever 39 side, and when the adjustment stop lever 39 is angularly displaced, the adjusting claw 43 It is sufficient if the roller is brought into contact with the teeth to stop the rotation of the roller, and various other conventionally known types may be used, and various other modifications are possible.

(Effects of the Invention) The present invention is configured as described above, and the printed body attached to the printing lever slides back and forth in conjunction with the operation of the handle, and engages with the printing lever to transfer the printed body to the tape. By providing a cam plate that is brought into contact and then separated, it is possible to print on a label, and a swingable claw attachment member and the tape that is swingably attached to the tip of the claw attachment member are fed out. a sensing claw that engages with the tip of the label adhered to the tape and causes a restorable angular displacement and angularly displaces the claw attachment member in conjunction with the angular displacement; and an adjustment/stop lever that automatically adjusts and matches the length of the tape fed out by the feeding mechanism with the angular displacement and stops the movement of the feeding mechanism. The tape feeding length can be automatically adjusted according to the length of the label, eliminating the need for delicate positioning adjustments, which is extremely convenient, and the engagement of the sensing claw with the label tip is released in conjunction with the return movement of the handle. By providing the disengagement member, it is possible to automatically prepare for the next tape feeding operation without any trouble. In addition, in the present invention, since printing is performed on the label and the label is peeled from the tape by feeding out the tape only when the handle is closed, even when the length of the label is long, the label can be printed without sagging. Can be easily and successfully applied to objects.
