〔Promoting Rice Techniques〵

Figure 11 shows a label/label equipped with a conventional labeling device.
1 is a schematic diagram showing the configuration of a l/issuing machine. The product 1.2 is placed on the tray 3 and moved from the right to the left in the figure by the weighing conveyor 4 and the transport conveyor 5. This vA weighing conveyor 4 measures the weight of the moving product l.

On the other hand, 6 is a label roll paper, and as shown in FIG. 12, a large number of 2-bells 7, 7, . . . are pasted at slight gaps r. This label roll paper 6 is guided by rollers 8 and sent to a printing section 9. The printing section 9 consists of a printer head 10, a platen roller 11, and a peeling member 12, as shown in FIG.
0 and the platen roller 211, the printer head 10 moves between the printer head 10 and the platen roller 11, and at this time, the label 7 is transferred to the weighing conveyor 4 mentioned above.
The weighed total value is printed. And the label roll paper 6 is attached to the printer head lO and the platen row jL/ll.
After passing between the strips 1 and 2, it is bent at an acute angle by the peeling member 12, guided by the rollers 13 and 14, and collected by the pick-up portion 15. In this case, the label roll paper 6 is bent at an acute angle by the peeling member 12, so that the label/l/7 is peeled off from the two-bell roll paper 6.
It hangs down and is blown up toward the lower surface of the labeling device 17 by the compressed air blown out from the sub-nozzle 16 . This labeling device 17 is provided with a suction device [18] having a built-in suction fan in its upper part, and the suction fan constantly rotates to maintain the inside of the suction chamber 19 at a negative pressure. Therefore, air flows into the suction N19 from the hole 20a formed in the suction plate 20 at the bottom of the suction chamber 19, and the blown up label 7 is thereby attracted to the suction plate 20.

In addition, in the suction chamber 19, a plurality of spray nozzles 21

is sprayed onto the top surface of the paper and pasted. In addition, label/
When the I/7 paper is attracted to the eL attaching plate 20, the sensor 23 detects this and stops the label roll paper 6 from moving backward, so that the label 7 is not issued twice.

[Problem that the invention seeks to solve]

By the way, the above-mentioned label pasting is performed continuously without stopping the transportation of the product, and the label issuing speed is extremely fast at 80 labels per minute. For this reason, when the tray on which the label 7yal was sprayed was moved without being attached sufficiently, the rear end side of the label 7yal was sometimes rolled up and blown off by the ejected air. It is known that this poor adhesion of Lape/L/7 tends to occur particularly in low temperature conditions where the glue hardens.

The present invention has been made in consideration of the above-mentioned circumstances, and an object of the present invention is to provide a label pasting device that can reliably paste labels.
