Description

[Detailed Description of the Invention] The present invention relates to an exhaust air device for a counting section in a paper sheet counting machine.

That is, in a paper sheet counting machine configured to count a group of paper sheets loaded into a holder by suctioning each sheet one by one with each suction head and turning them over, conventionally, paper sheets such as securities, stock certificates, etc. The stiffness of paper sheets differs depending on the paper quality and thickness, and the difference between circulation notes and new banknotes. As shown in Figure 6, compressed air is blown out from the lower exhaust pipe A to make it easier to separate the sheets one by one. This has the disadvantage that the paper sheet cannot be counted properly and the counting stops, so when counting, the paper sheets must be bent to make them weaker before counting, or the counting must be done manually. This is what I was looking for.

The present invention provides a simple structure that can be suitably implemented so that even such uncountable or difficult-to-count paper sheets can be counted reliably and satisfactorily.

The embodiments shown in the drawings will be described below.

FIG. 1 shows a plan view of the counting section, in which five suction heads 1 each having a suction hole 1a are rotatably installed around the upper part of the rotary cylinder 2, and a paper holder 3 is fixed to the side thereof. Load 5 groups of paper sheets into the holder 4 at the position indicated by the solid line in Fig. 1 and press the start button 6. The 5 groups of paper sheets held between the presser rod 7 are installed so as to be in contact with the suction head 1, and the upwardly facing An exhaust pipe A having an air outlet 8 is installed, and the structure is similar to that of the conventional type.

Reference numeral B designates a front exhaust pipe, which is arranged so as to be located in front of the tips of the five groups of paper sheets in the counting position, and can discharge compressed air from the front side of the tips of the five groups of paper sheets toward the side to be turned over by the suction head 1. The air outlet 9 can be formed in the shape of a long hole as shown in FIG. 4a, or in the shape of many round holes as shown in FIG. 4b, or as shown in FIG. 4c. As shown in FIG. 2, the size of the air outlet 9 can be adjusted by sliding a cylindrical metal 11 that can be freely tightened by a fastener 10 onto the front exhaust pipe B.

In addition, in Fig. 3, 12 is a vacuum pump,
The suction head 1 is connected to the vacuum pump 12 by piping.
communicates so that it performs an intake action while rotating,
The exhaust side of the vacuum pump 12 is connected to the lower exhaust pipe A and the front exhaust pipe B by piping, and control valves 13 and 14 are installed in the middle, and the control valves 13 and 14 are operated by a dial 15. In this case, a separate vacuum pump for the front exhaust pipe B may be provided. Further, as is well known, by utilizing the timing when a vacuum switch (not shown) is turned on and the rotary cylinder 2 starts rotating, for example, before that timing, compressed air is discharged only from the exhaust pipe A, and after that timing, the control valves 13 and 14 are automatically activated. It can be constructed so that compressed air can be discharged from the exhaust pipe B as well.

Therefore, when counting, paper sheets 5 are
When the rotary tube 2 rotates in the direction of arrow B and each suction head 1 rotates in the direction of arrow C, with the group being held between the holder 4 and the paper presser rod 7 and in contact with the suction head 1,
As shown in FIG. 5, each suction head 1 attracts one sheet and counts the sheets while turning them over.

In this case, compressed air is blown upward from the air outlet 8 of the lower exhaust pipe A in the direction of arrow D from below, and this compressed air is blown into the 5 groups of paper sheets and turned over by the suction head 1. The compressed air discharged from the air outlet 9 of the exhaust pipe B flows as shown by the arrow H, and the one sheet that is attracted to the suction head 1 can be easily turned over. 1, and the adsorption action is performed accurately without causing the defects shown in FIG.

In this way, the present invention is a paper sheet counting machine configured to count a group of paper sheets to be loaded into a holder by sucking them one by one with each suction head and turning them over. A lower exhaust pipe that blows up and discharges compressed air, and a front exhaust pipe that blows and discharges compressed air from the front side of the tip of the paper sheet toward the side where it is turned over by the suction head. A control valve is installed to appropriately adjust and distribute the compressed air blown out from the front exhaust pipes, so the suction head can be reduced to 1 by blowing out the compressed air blown out from both exhaust pipes, each adjusted to its optimum condition. It not only helps turn over sheets one by one, but also works to press one sheet against the suction head, and even strong sheets can be suctioned well and counted accurately. can solve the shortcomings,
It has a feature that it has a simple structure and can be suitably implemented.

Claims (1)

[Scope of utility model registration request] The configuration is such that each suction head picks up and counts sheets from a group of paper sheets loaded in the holder while turning them over. In a paper sheet counting machine having a structure in which compressed air outlets are formed at each approaching position, the compressed air discharged from the vacuum pump is communicated through a pipe so as to be discharged from the front and lower outlets, respectively. An exhaust air device for a counting section in a paper sheet counting machine, characterized in that a control valve is provided in the middle so that the amount and pressure of air blown out from a front exhaust port and a lower exhaust port can be adjusted as appropriate.
