Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention is particularly applicable to articles conveyed by a conveyor or the like.
The dimensions of the label pieces temporarily attached to the tape-like backing paper (label pitch ) is different, the present invention relates to an adjustment device that can appropriately set the transport path length corresponding to the label pitch up to the label peeling position.

(Prior Art) Conventionally, there is no label pitch adjustment device in this type of automatic label pasting machine, but there is a label pitch adjustment device of this kind in manual dispensers etc. No. 24250 discloses a means for adjusting the label pitch by a gear ratio linked to the operation of a switching lever, and Utility Model Application No. 61-43107 discloses a means for vertically moving a triangular feed adjustment member by adjusting an adjustment screw. Therefore, there are known means for adjusting the pitch of the label by increasing or decreasing the rotation stroke of the drive piece and changing the amount of rotation and reciprocation of the feed member that transports the label.

However, although these label pitch adjusting means are suitable for small manual models, they are not suitable for large automatic labeling machines such as the present invention.

(Problem to be Solved by the Invention) Therefore, the present invention makes it easy to appropriately adjust the length of the transport path corresponding to the pitch of the peelable label peeled off from the tape-like mount that is compatible with a large and automatic labeling machine. It is an object of the present invention to provide a device for adjusting the label transfer pitch which can be achieved more accurately.

(Means for Solving the Problems) In the present invention, in order to expand and contract the length of the transport path of the continuous label l consisting of a large number of labels temporarily attached at equal intervals on a tape-like mount, a bracket 5 is provided. At least a pair of turning rollers 24, 25 are provided on the adjustment member 70, which is rotatable in the label feeding direction and in the label feeding opposite direction about the provided pivot 71 as a fulcrum.
2.

(Operation) When the pitch of the labels 2 of the label continuous body 1 is large, it is necessary to extend the transport path length and appropriately set the transport path length corresponding to the label pitch.

In this case, loosen the adjustment screw 72 and adjust the adjustment member 70.
After setting the angle in the label feeding direction (to the left in FIG. 7) to a suitable angle, the adjustment is completed by tightening the adjusting screw 72.

Furthermore, if the pitch of the label continuous body l is small, the length of the transport path is reduced. In this case, the direction is set opposite to that of the expansion. That is, the adjustment member 70 is tilted in the opposite direction of label feeding (rightward in FIG. 7).

In this way, the transport path length of the label continuous body l is adjusted, so that
The label piece 2 temporarily attached to the tape-like mount 3 is reliably peeled off at its label peeling portion 26.

(Example) First, referring to FIG. 1 showing the overall configuration, a supply reel 10 winding a continuous label body l formed by temporarily attaching labels 2 at equal intervals on a tape-shaped mount 3 is as follows. The boss 1 of the support arm 12 fixed to the bracket 5 of the printer 4
It is fixedly held at 1. The fulcrum 13 of the supply reel 10 is the center of the boss 11.

Next, a tension arm 14 having a tension roller 16 that suspends the continuous label l on this support arm 12
is attached, and the arm 14 is configured to be vertically movable, and the arm fulcrum 15 is at a different position from the reel fulcrum 13, and both fulcrums 13 and 15 are eccentric. Furthermore, a spring 18 (fourth
(see figure) is interposed, and the tension arm 14 is always elastically biased to the push-up position by the elastic force of the spring 18. That is, the tension roller 16 on which the label continuous body l is suspended is always positioned in the direction of extending the transport path length of the label continuous body l (see FIG. 2), and in this push-up position, the outer periphery of the tension roller 16 is Reel lap of reel lO! 117 in pressure contact state (first
4), the arm fulcrum 15 is offset from the reel fulcrum 13 as described above.

A guide roller 19 is attached to the support arm 12, and guide rollers 20, 21, 22, etc. are attached to the bracket 5, and these guide rollers 19, 20, 21, 22, etc. are attached to the support arm 12, and guide rollers 20, 21, 22, etc. It is formed so that it can be sent to the

Next, it will be easier to understand if the transport route of the continuous label l is explained below before explaining the structure of each member including each device.

The means for transporting the label series I is usually the traction action of a traction roller 31 driven by the rotation of the motor 6. This label series 1 is thus guided by the guide rollers 20.21.2.
2, a label sensor 23, and a thermal head 41. Platen roller 4
2. The label continuous body l on which the desired printing has been applied in this part is a label peeling position adjustment member 7 equipped with a pair of turning rollers 24 and 25 that adjust the label conveyance pitch of the present invention.
0, a label peeling section 26 consisting of a rotating turning bin
leading to. Referring to FIG. 6 below, in this part, the label 2 is peeled off by turning the tape-like mount 3, and the conveyor 8
A label is pasted on the article 90 that is loaded on the vehicle and transported, and in this label pasting, the label pasting member 50
It has a depressing effect. This operation is a rotational depression operation of the labeling member 50 due to the protrusion of the plunger 52 of the solenoid 51.

Next, the label continuous body l after pasting the label 2 on the article 90 is made into a tape-like backing paper 3, and is placed on the guide rollers 27, 28, 29.
．． 30, the pulling roller 31 and the pressure roller 32, and is wound onto a take-up reel 34 attached to a take-up shaft 35.

Next, a device for adjusting the label peeling position in the distance between the printing section 40 and the label peeling section 26 will be described with reference to FIGS. 1 and 7.

To summarize this device, a pair of turning rollers 24 and 25 are provided between a printing section 40 consisting of a thermal head 41 and a platen roller 42 and a label peeling section 26 for expanding and contracting the transport path length of the continuous label l. A feature is that a label peeling position adjusting member 70 is provided which can be rotated. This adjustment device displaces the peeling position of the label 2 temporarily attached to the tape-like mount 3 due to the difference in size in the transport direction. It corresponds to the dimensions of label 2 and printer 4
The length of the continuous label l is adjusted between the printing unit 40 and the label peeling unit 26 that peels off the labels with a turning bin.

That is, as shown in detail in FIG. 7, there is an adjustment member that is rotatable left and right in FIG. Turning rollers 24 and 25 of the continuous label body 1 are attached to the upper and lower portions of 70, respectively, and are fixed to this pivot 71 portion with adjustment screws 72.

Therefore, the adjustment member 70 is displaced by turning it left and right as shown in FIG. 72 for the specific adjustment method that only needs to be tightened.
To explain in the figure, when the adjustment member 70 is displaced from the solid line to the state shown by the two-dot chain line, the printing part 4 of the label continuous body 1
The length from o to the label peeling part 26 becomes shorter. In this way, by changing the length of the continuous label l in the prescribed section according to the size of each label in the transport direction, the peeling position of the label piece 2 can be adjusted to the optimum position. .

Note that when adjusting the label peeling position for labels with short dimensions in the transport direction, if the reversal angle of the label continuous body 1 suspended between the pair of turning rollers 24 and 25 attached to the adjustment member 70 is steep, , each turning roller 24.
Since label peeling occurs at the 25 part, it is better to avoid setting a steep angle. In other words, in FIG. It is desirable to adjust the settings to a state close to .

(Effects of the Invention) As described above, in the label feeding pitch adjusting device of the present invention, the adjusting member 70 provided with at least a pair of turning rollers 24 and 25 uses the pivot shaft 71 as a fulcrum to adjust the label feeding direction and the label feeding pitch. Since the adjustment member 7 is rotatable in the opposite direction and has an adjustment screw 72 on the pivot 71,
It is easy to displace 0 to a certain angle. Therefore, there is an advantage that the length of the transport path of the continuous label l can be expanded or contracted to appropriately and accurately set the length of the transport path corresponding to the label pitch.
