Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label sticking device that moves between a label issuing position and a label sticking position to automatically stick a label to a product or the like.

2. Description of the Related Art The structure and operation of this type of label sticking apparatus will be described with reference to FIGS. First, a fixed wheel 2 is fixedly provided on the base 1, and a rotary shaft 3 is rotatably attached to the fixed wheel 2 and the base 1. A passive wheel 4 is fixed to the rotary shaft 3, and a pulse motor 6 is attached to the passive wheel 4 via a belt 5.
Are connected. Further, an arm 7 is attached to the rotating shaft 3.
Is fixed, 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. The movable wheel 9 and the fixed wheel 2 are connected by a belt 10. Further, a vertical connecting rod 11 is provided integrally with the movable wheel 9,
A label holder 12 is fixed to the lower end of the connecting rod 11. An opening (not shown) is formed in the label holder 12, and an air pressure supply device is connected so that the label 13 is sucked and released by the air pressure.

Then, the outer peripheral portions of the rotary shaft 3 and the support shaft 8 connected by the arm 7 are covered with a cover 14, and the whole thereof is a sticking arm 15.

Then, a fan-shaped blade body 16 is fixed to the end of the rotating shaft 3, and a sensor 17 for detecting the presence or absence of the blade body 16 by being positioned in the rotation trajectory of the blade body 16 is fixed in position. It is provided in.

In such a configuration, driving the pulse motor 6 causes the passive wheel 4 to rotate via the belt 5,
The rotary shaft 3 and the arm 7 integrated with the passive wheel 4 rotate. At this time, the fixed wheel 2 does not rotate.

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

Thus, FIG. 6 (a) shows the home position, FIG. 6 (b) shows the label suction position for sucking and holding the label 13, and FIG. 6 (c) shows the home position. Is the position where the label 13 is attached to the product. Then, from the home position to the label suction position, the pulse motor 6 operates based on the preset feed amount, and the position is set. Further, in the label attaching position, the label holder 12
A detector (not shown) provided at the position sets the lowered position and stops.

The home position is set, specifically, by setting the detection position of the blade 16 by the sensor 17 as the home position, and the label suction position and the label attaching position are set with reference to this home position. .

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. I have to. That is, the label suction position is set to a fixed value in relation to the label issuing machine, and the home position is set to keep the label suction position constant.
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 with a cover to protect it, but this cover changes the state of external light with respect to the sensor 17, and the detection position of the blade 16 is distorted. There is a problem that it has to be readjusted.

In addition, some trouble may occur during use and the serviceman may disassemble, but setting the home position is difficult at the shipping factory as described above, so adjustment by the serviceman is extremely difficult, and it takes time and time. There is a problem that it requires labor.

Means for Solving the Problems A label holding body that sucks and holds a label at the label suction position and releases the label at the label sticking position is provided on a sticking arm that is rotationally driven by a pulse motor, and the label suction position and the label sticking position. A home position setting means including a movable body and a sensor for setting the home position of the sticking arm is provided between the label holding body and the label holding position from the home position set by the home position setting means. A feed amount storage means for storing the movement amount to be moved to the pulse motor drive pulse is provided, and a feed amount setting means for manually changing the feed amount stored in the feed amount storage means is provided.

Since the movement amount for moving from the home position to the label suction position can be appropriately set by the feed amount setting means, the absolute position of the home position set by the home position setting means does not need to be accurate. Thus, 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 described with reference to FIGS. 1 and 2. Since the mechanical structure is the same as that shown in FIGS. 3 to 6, the description thereof is omitted and the same reference numerals are used for the same portions. Then, the main CPU 18 is provided. The main CPU 18 is connected to the ROM 19 and the backed-up RAM 20, and is also connected to the scale 21, the key / key controller 22, and the display 23. In addition, the main CPU 18 has a print buffer 24
And the interface 25 are connected. The keys and the key controller 22 also function as a feed amount setting means.

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

Furthermore, the interface 25 includes an arm CPU 2
9, the arm CPU 29 has a ROM 30, a backed up RAM 31, a DIP switch 32, a packaging machine interface 33, the pulse motor 6, and the sensor 17.
Is connected. The RAM 31 is provided with an area of a fetch position register as a feed amount storage means.

In such a configuration, the sticking arm 15 is sent to the home position and stopped when the power is turned on, but the operation is performed by the detection of the blade body 16 by the sensor 17. That is, when the sensor 17 is bright, it means that the sticking arm 15 has moved to the label sticking position side, and therefore the sticking arm 15 performs the “return operation”. The pulse motor 6 is driven for each pulse, and the sensor 17 drives the blade 16
The movement of the sticking arm 15 is stopped at the time when is detected, and the position is set as the home position.

Further, the fact that the sensor 17 is dark when the power is turned on means that the sticking arm 15 is moving to the label suction side, and therefore, the "body moving direction" until the blade body 16 is removed from the sensor 17 and the sensor 17 becomes bright. To generate a feed pulse. Then, when the sensor 17 becomes brighter, it advances by 5 to 6 pulses, and as described above, the operation of setting the home position from the bright state of the sensor 17 is performed.

After the home position is set in this way, the dip switch 32 selects normal operation or adjustment operation. Now, assuming that the normal operation mode is set, the contents of the fetch position register are read after the label is issued, and the label holder 12 attached to the sticking arm 15 moves to the label suction position. Fetch operation "is performed. Then, the label 13 is adsorbed and held, and then sent to the label attaching position, and after the label 13 is attached to the product, the home position is restored. Such normal operation is repeatedly performed.

Next, when the adjustment mode is set, that is, the feed amount from the home position to the label suction position is constant, and the label holder 12 at the label suction position is
If the position is not correct, the feed amount from the home position to the label suction position is changed without changing the position of the home position. That is, when the aster key is pressed, the contents of the fetch position register are read and the contents are fed in accordance with the contents, and the label holder 12 moves to the label suction position and stops. Therefore, the stop position of the label holder 12 is checked, and the feed amount to a desired position is input by the key and the key controller 22 which also functions as a feed amount setting means. As a result, the newly input numerical value is stored in the fetch position register. Then, the sticking arm 15 returns to the home position again and repeats the operation of stopping at the label suction position. The above-described numerical input of the feed amount is repeated until the stop at the label suction position reaches a desired state.

In this way, the most preferable label suction position can be obtained without changing the home position simply by inputting a numerical value. When the position is determined, the end key is operated and the adjustment mode is released to shift to the normal operation mode.

EFFECTS OF THE INVENTION As described above, the present invention is provided with the label holding body that sucks and holds the label at the label suction position and releases the label holding position at the label sticking position on the sticking arm that is rotationally driven by the pulse motor. Between the label attaching position and the label attaching position, home position setting means including a movable body and a sensor for setting the home position of the attaching arm is provided, and the label holder is set to the home position by the home position setting means. A feed amount storage means for storing the movement amount for moving from the label feed position to the label suction position as a drive pulse of the pulse motor, and a feed amount setting means for manually changing the feed amount stored in the feed amount storage means. Therefore, the moving amount to be moved from the home position to the label suction position is appropriately set by the feed amount setting means. Therefore, the absolute position of the home position set by the home position setting means does not have to be accurate, which allows the amount of movement from the home position to the label suction position while confirming the label suction state. This has the effect that settings can be made easily.
