Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a labeling device that affixes labels to articles while conveying them.

<Prior Art> Generally, in a weighing and pricing device, as shown in FIG. 9, articles W sent from a pre-stage conveyor 1 are conveyed by a weighing conveyor 2 and weighed by a weighing machine 3 attached to the weighing conveyor 2. While the article W is being conveyed by the conveyor 4 in the next stage, a labeler 5 installed above the article W is conveyed.
Label 6 on which the price corresponding to the weighing value is printed,
It is attached to the upper surface of the article W and sent to the next stage conveyor 7.

In order to ensure that the label 6 is affixed to the article W, width adjustment guides 8a and 8b are provided on both sides above the labeler conveyor 4, as shown in FIG. I have to.

However, the above-mentioned width adjustment guides 8a, 8
In method b, there is no problem if the articles W to be sequentially conveyed have the same shape, but a big problem arises when articles whose individual shapes are not uniform, such as handmade hams, are conveyed sequentially. That is, if the width, height, etc. are different, the distance between the width adjustment guides 8a and 8b must be adjusted to the width of the largest article, so as shown in FIG.
In the case of W', the orientation of the article W' is not constant, resulting in the inconvenience that the label 6 cannot be attached to a fixed position, or that the label 6 cannot be attached at all.

For this reason, it is proposed in Japanese Patent Application Laid-Open No. 62-78041 that two clamping and conveying belts made of flexible material are provided on both sides, and labels can be applied while the article is being conveyed between the two clamping and conveying belts. Conceivable.

<Problems to be Solved by the Present Invention> However, in the clamp conveyor belt of JP-A No. 62-78041, the distance between the two clamp conveyor belts is constant, so the overall size of the transported article is too large. If the belt is too small, the gripping and conveying belt will be greatly depressed, leading to rapid deterioration and the inability to grip the article elastically.On the other hand, if the article is too small overall, it will not be possible to grip the article with sufficient force. There was an inconvenience that it became difficult to convey the articles while arranging them in a certain direction.

In addition, since the adjustment article is held between flexible materials such as sponges, the flexible materials tend to deteriorate, and if the article is damp, the flexible materials will gradually absorb water and make the held items wet. Another problem was that it was difficult to attach labels to articles.

<Means for solving the above-mentioned problems> The purpose of the present invention is to solve the above-mentioned problems, and for this purpose, the articles conveyed by the conveyor are conveyed by means of first and second conveyors provided on both sides of the article conveyance direction. A labeling device for attaching a label to an article while pinching and conveying it with a pinching and conveying belt, further comprising an interval adjustment means that allows adjustment of the interval between the first and second pinching and conveying belts; , the second clamping and conveying belt is constituted by a flat belt, flexible members arranged at regular intervals along the longitudinal direction of the flat belt, and a covering material covering the flexible member. It is characterized by

<Function> With this arrangement, the article is conveyed while being held at an appropriate interval by adjusting the interval between the holding and conveying belts from both sides using the adjustment means.

A presser bar 59 having an upwardly curved tip is attached to the lower end of the frame 57 and presses down the label adhered to the article W.

Note that the label pasting conveyor has a label 52.
It is composed of a large number of round belts so as to be able to suction the objects W and to adapt to the curved surface of the article W.

As shown in FIG. 1b, the terminal end 14a of the labeler conveyor 14 and the front end 60a of the next stage conveyor 60
A bottom labeler 80 is provided in the base 16 for attaching a label on which the weight, price, etc. of the article W are printed from the bottom side of the article W in the gap between the two.

A tape (not shown) wound around the supply reel 81 of the underlay labeler 80 is taken up by the take-up roller 82 . Similar to the top labeler 15, labels are removably adhered to the tape at regular intervals,
The price and weight based on the measured value signal from the weighing machine 13 are printed on the label by the printer 83. Then, by similarly bending the tape at an acute angle and advancing the tape, the label is peeled off from the tape, and the peeled label is transferred to the terminal end 14a of the conveyor 14 and the front end of the next stage conveyor 60 by the belt 84. The article W is transferred to the gap between the two, attached to the lower surface of the article W, and pressed by an air injection device (not shown) or the like.

In order to synchronize the timing of label attachment to the article W, as shown in FIG. 1B, an optical article detector 90 is provided, and the label is attached at a timing based on this detection signal.

It is also possible to affix a label displaying the price etc. using the top labeler and affix a brand label using the bottom labeler.
Further, it is also possible to attach a label displaying the price, etc. to both the upper and lower labelers, and select either of the upper or lower labelers to attach only the top or only the bottom.

A frame body 61 is attached to the base 16 on the side of the next stage conveyor 60.

A rotation shaft 62 is rotatably attached to the frame 61 in a vertical direction. A rotating lever 63 is fixed to the upper end of the rotating shaft 62.

A cylindrical body 64 is screwed onto the rotation shaft 62,
The cylindrical body 64 rises when the rotary lever 63 is rotated in a certain direction, and falls when rotated in the opposite direction.

A housing 65 is fixed to the cylinder 64. The housing 65 is provided with two shafts 66a and 66b,
Cranks 67a and 67b are attached to these shafts 66a and 66b so as to be rotatable and spring-biased clockwise. A frame 68 is attached to the other ends of the cranks 67a and 67b in a vertical and horizontal direction. The frame 68 has pulleys 69a and 69b.
is rotatably mounted, and pulleys 69a, 69b
A presser belt 70 is attached between them.

The pulley 69a is driven by a motor 71 fixed to the frame 68, and the presser belt 70 is driven at the same speed as the next stage conveyor 60.

As shown in FIG. 7, the presser belt 70 is made up of a flat belt 70a, a flexible material such as a sponge 70b bonded to it, and a cloth material 70c attached to the flat belt 70a.
It has a recess in the center. Therefore, the tip of the presser rod 59 of the labeler 50 escapes into the recess 70d.

Therefore, the label 52 adhered to the top surface of the article W
is pressed by a presser bar 59 and then from both sides by a presser belt 70 as shown in FIG. 8, so that both sides of the label 52 in the width direction are securely affixed.

<Operation of the embodiment> With such a configuration, the articles W are weighed by the weighing conveyor 12, passed through the guide plates 40a and 40b of the labeler conveyor 14, and transferred to the nipping conveyor belt 36,
37, since it is conveyed while being pinched with dents on both sides.
Even if the articles W have various shapes and widths, they are conveyed without changing their orientation. During this clamping and conveyance, a label 52 with the product brand displayed on the upper side of the article W is attached by the top labeler 15, and a label 52 with the price, weight, etc. displayed on the lower side is attached to the bottom labeler 80. It is pasted by a presser bar 59, and is further pressed from both upper sides by a presser belt 70 to ensure that it is pasted.

<Effects of the present invention> As described above, in the present invention, even if the width of the article W is different, the holding and conveying belts 36 and 37 are concave and hold the article W, so that the article W can be held in a fixed direction and at a fixed position. Labels can be attached. Furthermore, even if the packaged film material protrudes, it is held and conveyed in a depressed manner, so no clogging occurs. Since the interval between the two clamping conveyance belts 36 and 37 can be adjusted according to the overall size of the article, the depressions of the clamping conveyance belts 36 and 37 are not large when the articles are clamped by the clamping conveyance belts 36 and 37. Since the gripping belts are neither too large nor too small, the deterioration of the clamping and conveying belts 36 and 37 is reduced, and the inconvenience of the articles being oriented unevenly due to insufficient clamping force can be eliminated.

In addition, since the flexible members are provided at regular intervals, they can easily dent even if the flexibility has sufficient elasticity, and the surface of the flexible member is covered with a covering material. Since the adjustment article does not come into contact with the flexible material, the flexible material is less likely to be damaged, and the inconvenience of the flexible material absorbing water and making the product wet, making it difficult to attach a label, can be eliminated.
