  However, in some molding factories, a sufficient space cannot be secured around the injection molding machine, and the label sticking device cannot be installed following the molding line. In this case, labeling is performed at a separate work site away from the installation site of the injection molding machine, and it takes time and labor to transport the molded product from the installation site of the injection molding machine to the work site. It was difficult to perform efficiently. In addition, at work sites, labeling is often performed manually, and the label position of the molded product is likely to be uneven, making it difficult to perform labeling work efficiently and incurs labor costs. There was a problem.

  The present invention has been made in view of the above circumstances, and its purpose is to provide a labeling system for a molded product that enables labeling to a molded product in a limited space around an injection molding machine. It is to be.

The labeling system for molded products according to the present invention is as follows:
A labeler that attaches a label to the molded product is installed in the molded product take-out path where the take-out machine takes out the molded product from the mold of the injection molding machine and conveys the molded product to the molded product release position on the side of the injection molding machine.
The labeler has a configuration in which a labeling operation is performed on a molded product that is held by the unloader when the unloader performs a labeling operation at the labeler installation position.
Thereby, since labeling can be performed by a series of operations for taking out the molded product by the take-out machine, labeling can be performed on the molded product within a limited space around the injection molding machine.

In the molded product release position, a conveyor for carrying out the molded product taken out from the injection molding machine by the take-out machine is disposed,
The labeler is preferably installed between the injection molding machine and the conveyor.
In this case, the labeler can be installed within the range originally occupied by the injection molding machine and the conveyor for carrying out the molded product, and it is not necessary to secure a space for installing the labeler around the injection molding machine.

The labeler includes a label peeling device that peels a label from a label continuous body in which a plurality of labels are temporarily attached to a strip-like peeling mount, a label sticking roller that sticks a label peeled by the label peeling device to a molded product, The label peeling device and the label sticking roller are arranged in parallel in the longitudinal direction of the injection molding machine, and the molded product is injected while being in contact with the label peeling device and the label sticking roller by the labeling operation of the take-out machine. It is desirable to adopt a configuration in which the label is attached to the molded product by moving in the longitudinal direction of the molding machine.
In this case, labeling with a labeler can be performed within a limited range along the longitudinal direction of the injection molding machine on the side of the injection molding machine. Therefore, even if a wide space is not secured on the side of the injection molding machine, labeling can be performed by a series of operations in which the take-out machine takes out the molded product within a limited space around the injection molding machine.

The labeler is provided on a horizontal support in an inverted L-shaped gantry having a vertical support and a horizontal support,
The vertical strut is disposed on the side where the safety door is retracted when the door is opened with respect to the lateral sliding safety door provided at the mold facing position on the side of the injection molding machine on the molded product release position side,
It is desirable that the horizontal struts extend toward the arrangement side of the unloader.
In this case, it is possible to open and close the safety door of the injection molding machine without obstructing the vertical column for installing the labeler, and it is possible to smoothly perform mold maintenance, inspection, setup change, and the like. Further, since the labeler is provided on the horizontal support extended toward the arrangement side of the take-out machine, the labeler can be accommodated in a space-saving manner without making a business trip around the injection molding machine.

The gantry on which the labeler is installed is preferably erected on a fixed table and installed independently of the injection molding machine.
In this case, even if the gantry on which the labeler is installed is not united with the injection molding machine and is installed independently from the injection molding machine, the labeler is always placed on a stable and stable base with sufficient weight. It is held in a stable posture. Accordingly, accurate labeling can be performed without causing the label position on the molded product to shift.
Further, since the labeler equipment part is independent of the injection molding machine, the labeler equipment part can be easily combined with or separated from the injection molding machine, and the labeler position can be easily adjusted. Therefore, the injection molding machine is not dedicated for labeling and can be used for various purposes (molds).

  As described above, according to the present invention, labeling can be performed on a molded product within a limited space around the injection molding machine. Therefore, even in a molding factory with a small site, it is possible to realize the automation of the labeling process of the molded product. In addition, since the labeling can be performed by a series of operations for taking out the molded product by the take-out machine, the labeling can be performed efficiently and accurately, and the cost of labeling can be reduced.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
As shown in FIG. 1, the labeling system for a molded product is installed on the side of the injection molding machine 1 for molding a molded product m such as a plastic container, and the molded product m is unloaded. Installed between the injection molding machine 1 and the conveyor 4, and a conveyor 4 for taking out the molded product m from the injection molding machine 1 and conveying it to the molded product release position on the conveyor 4. 2 and a labeler 3 for labeling the molded product m being conveyed.

  The injection molding machine 1 is a horizontal injection molding machine 1, and a movable platen 14 is moved by a mold clamping mechanism 11 to open and close the mold 12 (male mold 12 a and female mold 12 b), and the mold 12 is opened and closed. When the mold is clamped, the injection mechanism 13 fills the cavity of the mold 12 with the molten resin, and the mold 12 is opened when the molten resin is solidified and formed into the molded product m.

  The conveyor 4 is extended along the longitudinal direction of the injection molding machine 1, and when a fixed number of molded products m are placed by the take-out machine 2, the molded products m are intermittently carried out downstream.

  The take-out machine 2 is a traverse type take-out machine 2, which is attached and fixed on a stationary platen 15 of the injection molding machine 1, and on the side of the operation side of the injection molding machine 1 in a direction perpendicular to the longitudinal direction of the injection molding machine 1. A traverse arm 21 extending to the front, a front and rear arm 22 attached movably along the traverse arm 21 and extending in the longitudinal direction of the injection molding machine 1, and attached movably along the front and rear arm 22 and movable in the vertical direction And a lifting arm 23 that extends in the vertical direction and a take-out head 24 that is attached to the lower end of the lifting arm 23 and grips the molded product m.

  The take-out machine 2 controls the arms 22 and 23 and the take-out head 24 so that when the mold 12 of the injection molding machine 1 is opened, the take-out head 24 waiting above the mold 12 is put into the mold 12. The molded product m is gripped from the mold 12 and taken out above the mold 12. Then, the take-out head 24 in the state of gripping the molded product is moved laterally and the molded product m is conveyed toward the conveyor 4 on the side of the injection molding machine 1, and the take-out head is located at the installation position of the labeler 3 during the conveyance of the molded product. The labeling operation for moving the molded product m gripped by the label 24 while making contact with the labeler 3 is performed, and the labeling is performed on the molded product m while the takeout head 24 is in the gripped state. When the application of the label L is completed, the take-out head 24 is moved again toward the conveyor 4 to convey the label-formed molded product m toward the conveyor 4, and when it reaches the conveyor 4, the take-out head 24 is lowered. Then, the molded product m is released to the molded product release position on the conveyor 4. Thereafter, the take-out head 24 that has released the molded product m is raised, moved back to the standby position above the mold 12 of the injection molding machine 1, and waits until the next mold 12 is opened. The unloader 2 repeats the above operation as one cycle.

  The labeler 3 is in a molded product take-out path in which the take-out machine 2 conveys the molded product m from the mold 12 of the injection molding machine 1 to the molded product release position on the side of the injection molding machine 1. 4 (see FIG. 1A). Thereby, the labeler 3 can be originally installed within the range occupied by the injection molding machine 1 and the conveyor 4 for carrying out the molded product, and a space for installing the labeler 3 is secured around the injection molding machine 1. There is no need.

  As shown in FIG. 2, the labeler 3 includes a holding reel 33 that holds a continuous label body 31 in which a plurality of labels L are temporarily attached to a strip-shaped release mount 32 at a predetermined interval, and a tension roller 34 to a holding roller 33. The label continuum 31 supplied via the lower guide roller 35 and the first pressing roller 37 is folded at the tip to peel the label L, and the label L peeled by the label peeler 51 is formed. A label adhering roller 52 that presses and adheres to the product m, and a take-up reel 39 that winds the peeling mount 32 from which the label has been peeled off by the label peeling device 51 via the upper guide roller 36 and the second pressing roller 38; It has. The label sticking roller 52 extends from the label peeler 51, and the label peeler 51 and the label sticking roller 52 are juxtaposed in the longitudinal direction of the injection molding machine 1. The label peeling device 51 and the label sticking roller 52 are installed upward and have a structure in which the label L is stuck on the molded product m.

  The labeler 3 moves the molded product m in the arrangement direction of the label peeling device 51 and the label sticking roller 52 in a state where the molded product m is in contact with the label peeler 51 and the label sticking roller 52, and the molded product m is a predetermined label. When the sticking start position is reached, the holding reel 33 is rotated by a certain amount following the take-up reel 39, and the label continuous body 31 is turned back at the tip of the label peeler 51, whereby the label L is peeled off. The label L is pressed by the label sticking roller 52 and attached to the molded product m. At this time, since the label continuous body 31 is tensioned so as not to be loosened by the tension roller 34, the label L is attached to the molded product m without wrinkling.

  The labeler 3 includes a base 50 on which the above parts are arranged. The base 50 is attached to the gantry 6 through a shaft 53 with a height position and horizontal position adjustment mechanism. The gantry 6 includes an inverted L-shaped column part 63 having a vertical column 61 and a horizontal column 62 and a fixed table 64 on which the column unit 63 is erected.

  The vertical support 61 is disposed on the side where the safety door 16 is retracted when the door is opened with respect to the lateral sliding safety door 16 provided at the mold facing position on the side of the injection molding machine 1 on the molded product release position side. . In FIG. 1, a vertical support 61 is disposed on the left side of the safety door 16. Thereby, the vertical column 61 for installing the labeler 3 can be opened and closed without disturbing the safety door 16 of the injection molding machine 1, and the maintenance, inspection, setup change, etc. of the mold 12 can be performed smoothly. be able to.

  The horizontal support 62 extends from the upper part of the vertical support 61 toward the arrangement side of the unloader 2. That is, the horizontal strut 62 extends in the direction orthogonal to the transverse arm 21 (longitudinal direction of the injection molding machine 1) toward the transverse arm 21 side of the take-out machine 2 (see FIG. 1). A shaft 53 with an adjusting mechanism is attached to the horizontal support 62 and the base 50 is attached to the horizontal support 62 in a suspended state. Thereby, the labeler 3 can be stored in a space-saving manner without making a business trip around the injection molding machine 1.

  The fixed base 64 has a weight 65, and the gantry 6 is installed independently from the injection molding machine 1. Thus, even if the gantry 6 on which the labeler 3 is installed is not united with the injection molding machine 1 and installed independently from the injection molding machine 1, the gantry 6 is erected on the stable fixed base 64 by the weight 65. The labeler 3 is always held in a stable posture. Therefore, accurate labeling can be performed without the positional deviation of the label on the molded product m. Moreover, since the equipment part of the labeler 3 is independent of the injection molding machine 1, the equipment part of the labeler 3 can be easily combined with or separated from the injection molding machine 1 and the position of the labeler can be easily adjusted. Therefore, the injection molding machine 1 is not dedicated for labeling and can be used for various purposes according to various molded products m (molds 12). If the gantry 6 has a weight sufficient to stably install the labeler 3, the fixed base 64 may not have the weight 65.

Next, the operation of this labeling system will be described.
Below, the operation | movement which affixes the label L on the side surface m1 of the bottomed rectangular container (molded article m) which has the opening part m2 is demonstrated.

  As shown in FIG. 3, the molded product m molded by the injection molding machine 1 is held by the take-out head 24 of the take-out machine 2 and taken out above the mold 12, and the taken-out molded product m is taken out by the injection molding machine 1. It is conveyed toward the side conveyor 4. At this time, the take-out head 24 adsorbs the bottom surface of the container, which is the molded product m, in the horizontal posture when the molded product m is released from the mold 12, and transports the molded product m in the horizontal posture (FIG. 3). (See (a)). When the takeout head 24 that holds the molded product m reaches the installation position of the labeler 3 between the injection molding machine 1 and the conveyor 4 (see FIG. 3B), labeling is performed on the molded product m. .

  That is, as shown in FIG. 4, the take-out machine 2 controls the movement of the elevating arm 23 to lower the molded product m to a predetermined height (see FIG. 4A), and subsequently, the take-out head 24 holds it. A side surface (a side surface m1 of the molded product m, which is one side surface of the container) of the molded product m in the horizontal posture is attached to the label peeling device 51 and the label sticking roller 52 of the labeler 3. A labeling operation is performed in which the label peeling unit 51 and the label sticking roller 52 are moved in the longitudinal direction of the injection molding machine 1 while being in contact with each other (see FIG. 4B). At this time, when the molded product m reaches the label sticking start position, the label continuous body 31 is moved back at the tip of the label peeler 51 to peel off the label L, and the label L is peeled off by the label sticking roller 52. It is pressed and affixed to a predetermined position on the side surface m1 of the molded product m. Thereby, labeling is performed on the side surface m1 of the molded product m in the gripping state on the takeout head 24 of the takeout machine 2.

Subsequently, as shown in FIG. 5, the take-out machine 2 conveys the molded product m labeled in the gripped state by the take-out head 24 toward the conveyor 4, and the take-out head 24 that grips the molded product m moves the conveyor 4. When the upper position is reached, the take-out head 24 is rotated 90 degrees so that the gripping posture of the molded product m is set to a horizontal posture, the opening m2 of the molded product m is directed downward, the molded product m is lowered, and the conveyor 4, the gripping state of the take-out head 24 is released and the molded product m is placed on the conveyor 4 (see FIG. 5A). Thereafter, the take-out machine 2 raises the take-out head 24, rotates the take-out head 24 by 90 degrees to the original vertical position (see FIG. 5B), and waits above the mold 12 of the injection molding machine 1. Move back to position (initial position).
Thereafter, for each molding cycle of the injection molding machine 1, the above-described steps of “extraction / conveyance of the molded product m” → “labeling during conveyance” → “conveyance of the molded product m / release onto the conveyor 4” are performed. Repeat sequentially.

  As described above, according to the labeling system according to the embodiment, labeling with the labeler 3 can be performed on the side of the injection molding machine 1 within a limited range along the longitudinal direction of the injection molding machine 1. Accordingly, even if a wide space is not secured on the side of the injection molding machine 1, the label to the molded product m is obtained by a series of operations in which the take-out machine 2 takes out the molded product m within a limited space around the injection molding machine 1. Can be pasted. Therefore, even in a molding factory with a small site, the labeling process of the molded product m can be automated. In addition, since the labeling can be performed by a series of operations for taking out the molded product m by the unloader 2, labeling can be performed efficiently and accurately, and the labeling cost can be reduced.

In the above embodiment, the conveyor 4 is disposed at the molded product release position on the side of the injection molding machine 1, but a pallet, a stocker device, or the like may be disposed instead of the conveyor 4.
The labeler 3 is disposed between the injection molding machine 1 and the conveyor 4. If the molded product take-out path of the unloader 2 is installed, the labeler 3 is installed adjacent to the outside of the conveyor 4 or upstream of the conveyor 4. It is also possible to install them side by side.
The labeler 3 has a label peeling device 51 and a label sticking roller 52 arranged in the longitudinal direction of the injection molding machine 1. The label peeling device 51 and the label sticking roller 52 are orthogonal to each other in the longitudinal direction of the injection molding machine 1. It may be arranged in parallel to the direction, and may be moved in the direction perpendicular to the longitudinal direction of the injection molding machine 1 while the molded product m is brought into contact with the label peeling device 51 and the label sticking roller 52 by the take-out device 2 at the time of labeling.
Further, as shown in FIG. 6, the position where the label L is attached to the molded product m is controlled by operating the unloader 2 (see FIG. 6A), and the bottom surface m3 inside the container as the molded product m (see FIG. 6A). The label L can be attached to a surface other than the surface gripped by the take-out head 24, such as FIG. 6B.
