Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a labeling device that moves between a label issuing position and a labeling position and automatically applies a label to a product or the like.

BACKGROUND OF THE INVENTION The structure and operation of this type of labeling device will be explained with reference to FIGS. 3 to 6. First, a fixed wheel 2 is fixedly provided on a base 1, and a rotating shaft 3 is rotatably attached to the fixed wheel 2 and the base 1. A driven wheel 4 is fixed to the rotating shaft 3, and a pulse motor 6 is connected to the driven wheel 4 via a belt 5. Further, an arm 7 is fixed to the rotation shaft 3, a support shaft 8 is fixedly connected to the tip of the arm 7, and a movable wheel 9 is rotatably attached to the support shaft 8. . This movable wheel 9 and the fixed wheel 2 are connected by a belt 10. Furthermore, a vertical link 11 is provided integrally with the movable wheel 9, and a label holder 12 is fixed to the lower end of this link 11.

This label holder 12 has an opening (not shown) formed therein, and is connected to an air and air pressure supply device so that the label 13 is attracted and released by air pressure.

Thus, the outer periphery of the rotation shaft 3 and the support shaft 8 connected by the arm 7 is covered with a cover 14, and the entirety is used as a pasting arm 15.

Next, a fan-shaped blade body 16 is fixed to the end of the rotation shaft 3, and a sensor 17 is positioned in a fixed position within the rotation locus of the blade body 16 to detect the presence or absence of the blade body 16. It is set in.

In such a configuration, by driving the pulse motor 6, the driven wheel 4 is rotated via the belt 5, and the rotating shaft 3 and arm 7, which are integral with the driven wheel 4, are rotated. At this time, the fixed wheel 2 does not rotate.

The support shaft 8 at the tip of the arm 7 moves on an arc centered on the rotation shaft 3. Furthermore, the movable wheel 9 held by the support shaft 8 moves together with the support shaft 8, but the movable wheel 9 is connected to the fixed wheel 2 via the belt 10.
Since it is connected to the support shaft 8, it rotates relative to the support shaft 8, but does not rotate relative to the absolute coordinates. Therefore, the connecting rod 11 moves while maintaining its vertical state, and the label holder 12 moves without changing its direction.

6(a) is the home position, FIG. 6(b) is the label suction position where the label 13 is held by suction, and FIG. 6(C) is the home position. This is the position where the label 13 is attached to the product.

From the home position to the label adsorption position,
The pulse motor 6 operates based on a preset feed amount, and the position is set. Further, at the label pasting position, a lowered position is set by a detector (not shown) provided on the label holder 12 and the label holder 12 is stopped.

Specifically, the home position is set by using the position where the blade body 16 is detected by the sensor 17 as the home position, and the label suction position and the label pasting position are set based on this home position.

The problem to be solved by the invention The home position is the detection position of the blade body 16 by the sensor 17, but it is difficult to set the relative position of the blade body 16 with respect to the sensor 17, and the position must be adjusted many times during assembly. It won't happen. That is, the label suction position is fixed depending on the relationship with the label issuing machine, and setting this label suction position constant is the setting of the home position.

Therefore, if you do not set the home position correctly,
``There is a problem that the label 13 cannot be held accurately.

Further, as described above, after setting the home position, the sensor 17 is covered and protected, but this cover changes the state of external light to the sensor 17, and the blade body 1
There is a problem that the detection position of 6 becomes incorrect and has to be readjusted. 2Furthermore, some kind of trouble may occur during use, and service personnel may disassemble it, but the home position setting is set at the factory as described above. Since the condition is difficult even at the factory, it is reported that adjustments by service personnel are extremely difficult and require time and effort.

Means for Solving the Problem A label holder is provided on the labeling arm, which is rotatably driven by a pulse motor, to suck and hold the label at the label suction position and release the label from holding the label at the label pasting position. and a home position setting means including a movable body and a sensor for setting the home position of the pasting arm, and moving the label holder from the home position set by the home position setting means to a label suction position. A feed amount storage means for storing the amount as a drive pulse of the pulse motor is provided, and a feed amount setting means is provided for manually changing the feed amount stored in the feed amount storage means.

Since the amount of movement from the home position to the label suction position can be appropriately set by the action feed amount setting means, the absolute position of the home position set by the home position setting means does not have to be accurate. It is configured so that the amount of movement from the home position to the label suction position can be easily set while checking the label suction state.

Embodiment An embodiment of the present invention will be explained based on FIGS. 1 and 2. Since the mechanical structure is the same as that shown in FIGS. 3 to 6, a description thereof will be omitted, and the same parts will be denoted by the same reference numerals. A main CPU is provided, and a ROM 19 and a backed-up RAM 20 are connected to the main CPU 18, as well as a scale 21, a key and key controller 22, and a display 23. In addition, the main CPU1
8 includes a print buffer 24 and an interface 25.
are connected. Note that the key and key controller 22 also function as feed amount setting means.

A ROM 26 and a printer CPU 27 are connected to the print buffer 24, and a print section 28 is also connected thereto.

Furthermore, the interface 25 includes
PU29 is connected, and this arm CPU29 has R
The OM 30, the backed-up RAM 31, the dip switch 32, the packaging machine interface 33, the pulse motor 6, and the sensor 17 are connected. In addition,
The RAM 31 is provided with an area for a fetch position register as a feed amount storage means.

In such a configuration, when the power is turned on, the pasting arm 15 is sent to the home position and stopped, but this operation is performed by the sensor 17 detecting the blade 16. That is, when the sensor 17 is bright, it means that the pasting arm 15 has moved toward the label pasting position, and therefore the pasting arm 15 performs a "return operation." and,
The pulse motor 6 is driven every pulse, and when the blade body 16 is detected by the sensor 17, the movement of the pasting arm 15 is stopped and that position is set as the home position.

Also, the fact that the sensor 17 is dark when the power is turned on means that the pasting arm 15 has moved to the label suction side, so the blade 16 has come off the sensor 17 and the sensor 17 has moved to the label suction side.
A sending pulse is generated in the "progressing direction" until the sensor 17 becomes bright (5).
-6 pulses are advanced, and the home position is set from the state where the sensor 17 is bright as described above.

After the home position is set in this way,
The dip switch 32 selects between normal operation and adjustment operation. Assuming that the normal operation mode is currently set, after the label is issued, the contents of the fetch position register are read out, and the label holder 12 attached to the pasting arm 15 moves to the label suction position. A "fetch operation" is performed. Then, after holding the label 13 by suction, it is sent to the label pasting position, and the label 1 is attached to the product.
3. After pasting, return to the home position. Such normal operations are performed repeatedly.

Next, if set to adjustment mode, i.e.
If the feed amount from the home position to the label suction position is constant and the position of the label holder 12 at the label suction position is incorrect, the feed amount from the home position to the label suction position without changing the home position. Perform an operation to change the . That is, when the ASTAR key is pressed, the contents of the fetch position register are read out, and the label holder 12 is moved to the label suction position and stopped in accordance with the contents.

Therefore, the stop position of the label holder 12 is checked, and the amount of feed to a desired position is input using the key and key controller 22, which also functions as a feed amount setting means.

This causes the newly input numerical value to be stored in the fetch position register. Then, the pasting arm 15 repeats the operation of returning to the home position and stopping at the label suction position. The numerical input of the feed amount described above is repeated until the label is stopped at the desired label suction position.

In this way, the most preferable label suction position can be found by simply inputting the J value without changing the home position. Once the position is determined, the user operates the end key, cancels the adjustment mode, and shifts to the above-mentioned normal operation mode.

Effects of the Invention As described above, the present invention is provided with a label holder that sucks and holds a label at a label suction position and releases the label holding at a label pasting position on a pasting arm that is rotatably driven by a pulse motor. and a label pasting position, a home position setting means including a movable body and a sensor for setting a home position of the pasting arm is provided between the label pasting position and the pasting arm;
Feed amount storage means is provided for storing the amount of movement of the label holder from the home position set by the home position setting means to the label suction position as a drive pulse of the pulse motor, and the amount of movement is stored in the feed amount storage means. Since the feed amount setting means is provided to manually change the feed amount, the amount of movement from the home position to the label suction position can be appropriately set using the feed amount setting means. The absolute position of the home position does not need to be accurate, and this has the effect that the amount of movement from the home position to the label suction position can be easily set while checking the label suction state.
