Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a die-cut label conveying device that separates and transports roll labels that are continuously punched into predetermined shapes into die-cut labels and label waste. It is.

[Conventional technology]

Conventionally, there has been known a die-cut label conveying device in which a roll label is continuously punched out using a rotary die-cut machine, and the roll label is separated and transferred into a die-cut label to be affixed to a container and label scraps. ing. In such devices, the punched labels are separated into die-cut labels and label scraps by a separate guide, one die-cut label is suction-transferred by the receiving-side pasting drum, and the other label scraps are It is automatically wound onto the rewind reel.

[Problem that the invention attempts to solve]

Since the conventional Daikatsu Travel conveyor device is configured as described above, it is necessary to make fine adjustments to the shape of the separate guide that separates the punched labels, the position of the label relative to the orientation, etc. Since the separated label waste with holes is collected by winding it up on a rewind reel, there was a problem that if the remaining width was set to a small value, it would be torn off by the winding force and could not be collected. In addition, after punching, the Daikatsu label advances to the pasting drum with its own strength without any restraints, so depending on the quality of the label paper, the delivery to the pasting drum may be unstable. It was hot.

The above problem can be solved by cutting the roll label in advance to a predetermined length in the transport direction, and then intermittently punching out the cut labels of the predetermined length, as shown in Japanese Patent Application Laid-Open No. 60-44298. This can be solved by punching and separating the labels in the pre-processing section, but in the case of such products, not only does it become necessary to separately process the fragmented and scattered label scraps, but also the above-mentioned pre-processing section is This method requires cutter equipment, complicates the structure of the device, has many adjustment parts, and is disadvantageous in terms of ease of assembly and poor economic efficiency.

In view of the above points, the present invention enables accurate label delivery without using a rewind reel, and is compatible with all label shapes that produce continuous label scraps and other label shapes that produce fragmented label scraps. It is an object of the present invention to provide a conveying device for a die cutlet traveler that can carry out efficient lees removal processing.

[Means for solving problems]

The Daikatsu Travel conveying device of the present invention includes a label separation drum in which a plurality of intake and exhaust holes are formed on the outer periphery, and an intake/exhaust control that distributes and controls intake and exhaust air to the intake and exhaust holes according to the rotational position of the label separation drum. a rotary die cutter that is arranged opposite to the label separation drum and continuously punches roll labels into a predetermined shape; and a rotary die cutter that is arranged to face the label separation drum and continuously punches out roll labels into a predetermined shape; The label separating drum includes a receiving drum disposed close to the label separating drum, and a suction duct disposed downstream of the label transfer path of the label separating drum and opened close to the label separating drum. A first suction/discharge hole located in the punched label part and a second suction/discharge hole located in the label removal part are opened separately, and the suction/exhaust control mechanism has a first suction/discharge hole located in the roll label contact position. a negative pressure circuit that connects the first suction and exhaust hole to a receiving side drum approach position and the second suction and exhaust hole to a duct approaching position, respectively, to a negative pressure source; A pressurizing circuit is provided for communicating the second suction/discharge hole with a pressurizing source at each duct opening position.

[Effect]

In the present invention, the punched die-cut labels are jetted from the label separation drum to the pasting drum to ensure reliable delivery, and the label scraps are sucked directly from the label separation drum through a duct. Because it can be discarded, it can be disposed of without using a rewind reel, and can be used for all label shapes that produce continuous label scraps or other label scraps that are fragmented. It becomes possible to perform processing.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on FIGS. 1 to 5. In the figure, 1 is a label roll stand, 2 is a roll label attached to this label roll stand 1, 3 is a pair of pull-out rollers for pulling out this roll label 2, and 4 is a pair of pull-out rollers that are pulled out by this pull-out roller 3. This is a label separation drum that transports the roll label 2, and transports the roll label 2 while continuously punching it into a predetermined shape by a rotary die cutter 5 disposed close to the upstream side of the label transport path, and transports the roll label 2 while continuously punching it into a predetermined shape. At a part of the pasting drum 6 located closer to the downstream side of the label transport path than the pasting drum 5, only the punched die cut label 2a (shown by the imaginary line in FIG. 5) is delivered to the pasting drum 6, and further the pasting drum 6 The opening 7a of the duct 7 is located closer to the downstream side of the label transport route than the opening 7a of the duct 7.
This section has a function of discarding the perforated label scraps 2b (shown by imaginary lines in FIG. 5) separated from the die-cut label 2a into the duct 7.

As shown in FIGS. 3 and 4, the label separation drum 4 is provided with a large number of vertical holes 4b in the circumferential direction extending from the upper surface 4a in the direction of the cylinder axis, and the setting mode of these vertical holes 4b is as follows. Circumferential direction as shown
The same pattern is repeated every 120 degrees, and each vertical hole 4b is provided with a plurality of horizontal holes 4d that communicate in the radial direction from the outer circumferential surface 4c, as shown in the developed view of FIG. In addition, the horizontal holes 4d in each vertical hole 4b are set so that the same pattern is repeated every 120 degrees. In other words, one die-cut label 2a is set to fit within a range of 120 degrees on the outer circumferential surface 4c, and three die-cut labels 2a can be transferred in one rotation of the label separation drum 4.
Further, the vertical hole 4b is formed of a vertical hole 4b' on the outer circumferential side and a vertical hole 4b'' on the inner circumferential side, and two separate ventilation paths are formed when the label separation drum 4 rotates. In addition, the horizontal hole 4d also has a horizontal hole 4d' for the die cutlet label 2a which communicates with the vertical hole 4b' on the outer circumferential side, and a label scraper 2b which communicates with the vertical hole 4b'' on the inner circumferential side. The vertical hole 4b and the horizontal hole 4d formed as described above constitute the suction/exhaust hole of the label separation drum 4, and the suction/exhaust hole for these suction/discharge holes is It is controlled by a valve disc 8 (FIG. 2) installed in contact with the upper surface 4a of the label separation drum 4.The valve disc 8 is
It allows the upper surface 4a of the label separation drum 4 located on the back side to slide, and communicates with the suction/discharge hole at a negative pressure circuit 8a section and a pressurization circuit 8b section formed in the valve disc 8. I'm starting to get it. Therefore, when the label separation drum 4 rotates, the die cutlet travel suction/discharge hole (hereinafter referred to as suction/discharge hole A) consisting of the vertical hole 4b' and the horizontal hole 4d'
is controlled by switching to negative pressure from the contact point of the roll label 2 on the label separation drum 4 to the vicinity of the approach position of the pasting drum 6, and to pressurization at the position facing the pasting drum 6 and the opening position of the duct 7, and vertically. The label waste suction/discharge hole (hereinafter referred to as suction/discharge hole B) consisting of the hole 4b'' and the horizontal hole 4d'' has negative pressure from the front side of the contact position of the roll label 2 to the vicinity of the duct 7 approach position, and the duct opening It is controlled to switch to pressurization depending on the position.

Note that 9 is a blower provided in the duct 7 and sucks the label scraps 2b which are sprayed and discarded from the label separation drum 4;

In the die cut label conveying device of the present invention constructed as described above, the roll label 2 punched out by the rotary die cutter 5 has the die cut label 2a in the suction/discharge hole A of the label separation drum 4.
As a result, the label waste 2b is sucked through the suction/discharge hole B.
They are each sucked and held and transported. When the pasting drum 6 is moved to a position opposite to it, air is fed into the suction/discharge hole A and the daikatsu label 2
A is ejected toward the pasting drum 6 and delivered to the pasting drum 6, and the delivered die-cut label 2a is attracted to the circumferential surface of the pasting drum 6 and transferred to the container conveyance path 10 side. At this time, suction and exhaust hole B
is in the negative pressure circuit 8a of the valve disc 8, so the label waste 2b remains adsorbed on the label separation drum 4. Then, when the label separation drum 4 rotates further and the label waste 2b is transferred to the opening 7a position of the duct 7, air is sent into the suction/discharge hole B and the label waste 2b is jetted toward the duct 7 and disposed of. The label scraps 2b in the duct 7 are sucked by the blower 9 and transported.

Therefore, in the device of the present invention, there is no need for a rewind reel as in the conventional case, and there is no load such as winding force on the label waste 2b. Even if the label were torn, there would be no impact on the upstream side of the label transport path.

In the above embodiment, the label scraps 2b are generated on the upper, lower, left, and right sides of the die-cut label 2a. It can be set as appropriate within the range of the pressurizing circuit 8b, and for example, as shown in FIGS. 6 to 8, a suction/discharge hole is applied to a case where the label waste 2b is generated only on the left and right sides of the die cutlet label 2a. It is also easy to form the label separation drum 11 having A and B.

[Effect of idea]

As described above, according to the present invention, by jetting and transferring the punched die-cut labels from the label separation drum to the pasting drum, it is possible to reliably transfer the punched labels, and also to transfer label scraps directly from the label separation drum. Since it can be disposed of by suction through a duct, it can be disposed of without using a rewind reel, allowing accurate label delivery and handling for all label shapes, including those that produce continuous label scraps and other labels that produce fragmented label scraps. This has the effect of enabling efficient lees removal processing.
