JP3671638B2 - In-mold label device with multiple quadrangular shaped products - Google Patents

Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a plurality of in-mold label apparatuses.
[0002]
[Prior art]
Conventionally, when a label is in-molded into a mold for taking two quadrangular shaped products, four labels are picked up from a label magazine by a robot, and are put in and out of the mold four times.
[0003]
[Problems to be solved by the invention]
The prior art has problems that the tact time is long because the robot is repeatedly put in and out of the mold four times, and the entire apparatus becomes large.
[0004]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention provides a single-axis robot having two parallel shafts that can be moved in and out of a mold for obtaining a plurality of quadrangular shaped products. A finger device in which suction fingers are mounted in a mountain shape in a direction of 45 ° with respect to the moving direction is fixed to both sides of the parallel shaft, and a label magazine that can face the finger device is arranged in a mountain shape outside the finger device. Then, each finger device is moved forward in order and slid outward at a right angle with the parallel shaft at a predetermined position so that the suction finger can be positioned at the label suction position of the label magazine. It is characterized in that the label can be adsorbed.

DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described in detail based on one example shown in FIGS.
Reference numeral 1 denotes a mold for taking two angle forming products each having four surfaces 2a, 2b, 2c and 2d on both open surfaces. Reference numeral 3 denotes a label suction and supply device, in which a single-axis robot 4 having shafts 5 and 6 parallel to the central portion is disposed so as to be able to advance and retract. The suction fingers 7, 8, 9, 10 are fixed to the parallel shaft 5, and the suction fingers 11, 12, 13, 14 are fixed to the other parallel shaft 6. A label magazine 15 is disposed so as to face the suction fingers 7 and 9, a label magazine 16 is disposed so as to face the suction fingers 8 and 10, and label magazines 17 and 18 are similarly fixed on the opposite side. Reference numeral 19 denotes an opening / closing device that slides the suction finger outward at a right angle. 20 is a parison.
[0006]
Next, the operation will be described.
(1) First, the single-axis robot 4 is advanced to the position shown in FIG. Next, it moves in the horizontal direction, sucks the label of the label magazine 16 with the suction finger 8 and returns to the original position.
(2) Next, as shown in FIG. 3, the single-axis robot 4 is moved forward and moved in the horizontal direction, and the labels of the label magazines 16 and 15 are sucked by the suction fingers 10 and 7 and returned to their original positions.
(3) Next, as shown in FIG. 4, the single-axis robot 4 is further advanced, moved in the horizontal direction, and the labels in the label magazine 15 are sucked by the suction fingers 9 and returned to the original position.
The above description has been made on the left side of the single-axis robot 4, but the same operation is performed simultaneously on the right side.
(4) Next, the suction finger is inserted into the opened mold 1 and the labels sucked by the suction fingers 7, 8, 9, 10 are brought into contact with the suction surfaces 2a, 2b, 2c, 2d in the mold 1 Then, the suction finger is returned from the mold 1 to the original start position.
Note that the quadrangular shaped product is not limited to two, and any number may be used.

【The invention's effect】
According to the present invention, a single-axis robot having two parallel shafts that can be moved in and out of a plurality of quadrangular shaped products is disposed so as to be movable back and forth, and is 45 ° to the moving direction of the single-axis robot. A finger device having an angled suction finger attached to the direction is fixed to both sides of the parallel shaft, a label magazine that can be opposed to the finger device is arranged outside the finger device in a mountain shape, and each finger device is advanced in order, It slides outward at right angles to the parallel shaft at a predetermined position so that the suction finger can be positioned at the label suction position of the label magazine so that the label can be sucked to each suction finger while the finger device is sequentially advanced. Therefore, when taking a plurality of quadrangular shaped products, the label can be adsorbed to the inner surface of the mold at the same time, the tact time can be reduced to a fraction of the conventional one, and the adsorption finger can be removed. Can reduce the overall size of the so it can be sufficiently reduced abuts distance Le magazine.

Claims (1)

A single-axis robot having two parallel shafts capable of entering and exiting a plurality of quadrangular shaped products can be moved forward and backward, and suction fingers are placed in a direction of 45 ° with respect to the moving direction of the single-axis robot A finger device mounted in a chevron is fixed on both sides of a parallel shaft, and a label magazine that can be opposed to the finger device is arranged outside the finger device in a chevron shape. In order to allow the suction fingers to be positioned at the label suction position of the label magazine by sliding outward at a right angle, a plurality of quadrangular shaped products can be picked up so that the labels can be sucked into each suction finger while the finger device is moved forward. In-mold label device.
