Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label sticking apparatus, and more particularly to a label sticking apparatus for sticking a label to an article to be stuck which is successively conveyed.

[0002]

2. Description of the Related Art FIG. 11 is a perspective view showing a conventional label sticking apparatus. The label sticking device 1 is for sticking a label on the bottom surface of a container for processed food such as jelly. The label sticking device 1 includes a base 2. The base 2 is horizontally provided with a transporting means 3 for transporting an adherend W to which a label is to be attached to a label attaching position. The conveying means 3 is, for example, a belt conveyor. Below the conveying means 3, two label sticking means 4 and 5 provided so as to complement each other are fixedly provided. The label sticking means 4 and 5 are for transferring the label continuum, peeling off the label temporarily attached on the label continuum, and sticking the label to the adherend. When applying the label, only one of the label applying means 4 and 5 is used and the other is stopped. Also, the label sticking means 4, 5
Includes peel plates 6 and 7 for peeling the label from the label continuum and sticking the label to the bottom surface of the adherend. The peeling plates 6 and 7 are provided so as to project obliquely from the lower side to the upper side of the conveying means 3 and the tip end portions thereof have the conveying means 3
It is provided so as to come into contact with an adherend to be conveyed over. When the adherend comes into contact with the peeling plates 6 and 7,
The label peeled from the label continuum A is attached to the bottom surface of the adherend.

[0003]

However, when the label remaining amount of one of the label attaching means 4 and 5 becomes small or runs out, the label attaching means 4 and 5 are stopped and the other label attaching means is applied. It becomes necessary to use means 5,4. Then, while the other label sticking means 5 and 4 are being used, it is necessary to carry out a replenishment work of the labels of the one label sticking means 4 and 5. In this case, in the conventional label sticking apparatus 1, the operation of stopping one of the label sticking means 4, 5 and then actuating the other of the label sticking means 5, 4 is performed by the operator for each of the label sticking means 4, 5. Had to do it manually. That is,
First, the transporting means 3 is stopped, and then one of the labeling means 4, 5 in use is stopped. Then, the other labeling means 5, 4 must be activated. Therefore, the label sticking work must be stopped until the switching work of the label sticking means 4 and 5 is completed, and the work efficiency is lowered. Further, the switching operation described above has a disadvantage that the label is likely to be stuck or peeled off twice.

Further, the conventional label sticking apparatus 1 is provided with label sticking means 4 and 5 fixedly. At the leading ends of the peeling plates 6 and 7, the peeling mount of the label continuum A is folded back at an acute angle, and is arranged so as to come into contact with the bottom surface of the adherend being conveyed. Therefore, even when one of the label sticking means 4 and 5 is used, the peeling plates 7 and 6 of the other label sticking means 5 and 4 continue to contact the adherend. At this time, since the label sticking means 5 and 4 on the other side stop the transfer of the label continuum, the same portion of the peeling mount of the label continuum A is abraded by the adherend conveyed thereon. It will be.
Therefore, the label continuum A is easily damaged such as being cut. Further, in the case where the adherend is a processed food such as jelly, it is often stored in refrigeration before the label sticking work, so that water drops or the like are often attached to the adherend. In that case, a label continuum A made of paper material or the like
The release liner is more likely to be damaged. Further, this water drop may be transmitted from the tip portions of the other peeling plates 7 and 6 and cause a failure of the label sticking means 4 and 5.

Therefore, a main object of the present invention is to perform the switching work between the first labeling means and the second labeling means efficiently without stopping the labeling operation. It is to provide a device.

Another object of the present invention is to provide a label sticking device in which the label continuum and the label sticking means are less likely to be damaged.

[0009]

The transport means continuously transports a plurality of adherends to which labels are to be attached. The first label sticking means provided in the vicinity of the conveying means sticks the label to the sticking object every time the first detecting means detects the sticking object to which the label is not stuck. When switching from the first label sticking means to the second label sticking means, the switching means
The first label attaching means is switched to the second label attaching means. Then, the first label attaching means stops the label attaching. Next, the second detection means detects the non-labeled pasted object that has passed through the first detection means after the first label sticking means is stopped. Then, the second label attaching means is activated to attach the label to the non-labeled adherend detected by the second detecting means. Therefore, double sticking of the label is prevented. When switching from the second label sticking means to the first label sticking means,
The switching means switches from the second label sticking means to the first label sticking means. Then, the first detection means detects the adherend to which the label is not attached. Then, the first label sticking means starts sticking the label to the sticking object detected by the first detecting means. Next, by the second detection means, after the operation of the first labeling means,
The pasted object with the pasted label, which has passed through the first detection means, is detected. Then, the second label sticking means stops the label sticking. Therefore, the sticking of the label is prevented. Furthermore, when the first displacing means and the second displacing means are included, the first label sticking means and the second label sticking means are kept away from the adherend when not in use, and the adherend when used. Approached. Further, the alarm means is the first

Next, with reference to FIGS. 1 to 4, the operating condition of the first label sticking machine 300a will be described. First, the transport device 200 starts transporting the adherend W (without a label). A plurality of adherends W are sequentially conveyed. The adherend W is guided by the guide plate 216 to an appropriate position for attaching a label on the conveyor belts 206, 208, 210. When the adherend W is transported to the upstream side of the first label sticking position 212,

Next, referring to FIG. 5, a case where the label C is attached to the adherend W (label not attached) by the second label attaching machine 300b will be described. In this case, the second label sticking machine 300b is moved up by the second cylinder 400b so as to approach the sticking target W, as shown in FIG. At this time, the first label sticking machine 300a is lowered by the first cylinder 400a so as to move away from the sticking target W. Therefore, it is possible to prevent the label continuum A of the first label sticking machine 300a from being damaged by the sticking object. Second labeling machine 3
00b operates in the same manner as the first label sticking machine 300a to stick the label C to the sticking target W.

Next, referring to the illustrations shown in FIGS. 4 to 7 and the flow chart shown in FIG. 9, the operation for switching between the first label sticking machine 300a and the second label sticking machine 300b. , And the operating status will be described. For switching the label sticking machine, for example, the remaining amount of the label continuum A of one label sticking machine becomes small, and the label continuum A is replenished,
This is done when it has to be replaced. Figure 9
(A) is a flow diagram showing an operation and an operation state when switching from the first label sticking machine 300a to the second label sticking machine 300b. In step S101, when the remaining amount of the label continuum A of the first label sticking machine 300a becomes small, the first alarm device 500a is driven and, for example, a yellow lamp blinks. Then, the operator switches the changeover switch 702 from the first label sticking machine 300a to the second label sticking machine 300b. Next, step S
At 103, the first label sticking machine 300 that has been operating until then in the state shown in FIG. 4 stops operating and descends, as shown in FIG. Next, in step S105, the first
It waits until the pasted object Wr (labeled) already conveyed between the passage sensor 218 and the second passage sensor 220 has passed the second passage sensor 220. And
The second passage sensor 220 has the first label attaching means 30.
When the adherend W (label not attached) that has passed through the first passage sensor 218 is detected after the stop of 0a, step S10
Proceed to 7. In step S107, as shown in FIG.
The second label sticking machine 300b rises and sticks the label C on the sticking target W (label not stuck) detected by the second passage sensor 220. Therefore, the double sticking of the label C is prevented.

FIG. 9 (B) is a flow chart showing the operation and operation status when switching from the second label sticking machine 300b to the first label sticking machine 300a. In step S111, the changeover switch 702 is switched from the second label sticking machine 300b to the first label sticking machine 300a. Next, in step S113, the first label sticking machine 300a, which has been lowered and stopped until then in the state shown in FIG. 5, moves to the label sticking position 21 as shown in FIG.
Ascend to 2 and label C on the adherend W (label not attached)

The operation of the second label sticking machine 300b until the pasted object (unlabeled) conveyed between the second passage sensor 220 and the second passage sensor 220 passes through the second passage sensor 220. Is continued. Then, when the second passage sensor 220 detects the adherend Wr (labeling completed) that has passed through the first passage sensor 218 after the operation of the first label attaching unit 300a, the process proceeds to step S117.
In step S117, as shown in FIG. 4, the second label sticking machine 300b stops operating and descends. Therefore, sticking of the label C is prevented.

Next, referring to FIG. 10, the operating states of the first alarm device 600a and the second alarm device 600b of the label sticking device 100 will be described. Figure 10
(A) is a timing diagram when the first labeling machine 300a is operating normally. When the adherend W passes the side of the first passage sensor 218, the first passage sensor 218 detects the adherend W. Then, the transfer of the label continuum A is started, and the transfer signal of the label continuum A is turned on. At the same time, the check signal for checking the transfer state of the label continuum A is turned on. Then, the label C is attached to the adherend by the first label attaching machine 300a. Further, when the label sensor 308 detects the next label C, the transfer signal of the label continuum C is turned off. Next, the check signal is turned off after a predetermined time has elapsed.
At this time, if the transfer signal of the label continuum A is off, the alarm signal remains off and the alarm device is not driven. The same applies to the second label sticking machine 300b.

FIG. 10B shows a first label sticking machine 30.
It is a timing chart when 0a abnormally operates. When the adherend W passes the side of the first passage sensor 218, the passage sensor 218 detects the adherend W. Then, the transfer of the label continuum A is started, and the transfer signal of the label continuum A is turned on. At the same time, the check signal for checking the transfer state of the label continuum A is turned on. And
The label C is attached to the adherend by the first label attaching machine 300a. If the label C is lost or the release liner B is cut off, the next label C is not detected. Therefore, when the check signal turns off after a predetermined time has passed, the transfer signal of the label continuum A remains on. In this case, the first alarm device 600a
Is turned on, the first alarm device 600a is driven, and, for example, a red lamp is turned on. When the second label sticking machine 300b is abnormally operated, the second alarm device 600b is similarly operated.

According to the label sticking apparatus 100 of this embodiment, the switching between the first label sticking machine 300a and the second label sticking machine 300b is stopped while the carrier device 200 is operated. It can be done automatically and continuously without. Moreover, the first labeling machine 30
When switching from 0a to the second label sticking machine 300b, double sticking of the label C is prevented. Further, when switching from the second label sticking machine 300b to the first label sticking machine 300a, sticking of the label C is prevented.
Therefore, according to the label sticking apparatus 100 of this embodiment, the efficiency of the label sticking work can be improved.
Further, the first cylinder 400a and the second cylinder 400b respectively keep the first label sticking machine 300a and the second label sticking machine 300b away from the adherend W when not in use. Therefore, abrasion of the label continuum A due to the adherend W to be conveyed and adverse effects of water drops do not occur, and the label continuum A and the label sticking machine are less likely to be damaged.

In the above embodiment, the switching between the first label sticking machine 300a and the second label sticking machine 300b is performed by changing the changeover switch 702.
The method is not limited to this, and may be automatically performed. That is, when the sensor of the supply reel 304 detects the remaining amount of the label continuum A, the alarm device is driven and
First labeling machine 300a and second labeling machine 30
Sequence control may be performed so that 0b is automatically switched.

The first label sticking machine 300a and the second label sticking machine 300b are not limited to being arranged below the conveying device 200, and for example, the conveying device 200 can be used.
It may be arranged laterally or above. When it is provided on the side of the carrier device 200, for example, the first labeling machine 30
0a and the second label sticking machine 300b may be horizontally movable and fixed to a column or the like continuously provided on the base 102.
In addition, when it is provided above the transport device 200, for example, a frame for fixing the first label sticking machine 300a and the second label sticking machine 300b so as to be vertically movable is provided above the carry device 200. And the first
Labeling machine 300a and second labeling machine 30
0b is fixed to the frame so as to be vertically movable. The horizontal movement and the vertical movement can be performed by the hydraulic cylinder as in the above-mentioned embodiment. In these cases, the label C can be attached to the side surface or the upper surface of the article W to be attached, and moreover, the same effect as that of the above-described embodiment can be obtained.
