Sheets counting device

Abstract

A sheets counting device comprising a hopper filled with a plurality of sheets in a stacked state, a carrying mechanism for delivering one by one sheets filled in the hopper into a carrying path and carrying them along the carrying path, a sensing unit having at least a counter for counting sheets and an identifier for identifying sheets, and stacker for stacking sheets delivered from the carrying path. The carrying mechanism comprises a drive roller constituting the inside of a turn unit for changing the direction of the carrying path, a plurality of pinch rollers for urging sheets toward the outer peripheral surface of the drive roller, and turn guide plates disposed between the plurality of pinch rollers so as to guide sheets along the outer periphery of the drive roller, wherein the turn guide plates are formed so as to guide the tip ends of sheets carried to the turn unit to contact portions between pinch rollers disposed on the downstream side out of the plurality of pinch rollers and the drive roller. The carrying path has a bend so formed on the upstream side of the counter and the identifier as to prevent thin and hard foreign matters other than sheets from passing.

Description

technical field [0001] The present invention relates to a sheet counting device that stores a plurality of sheets placed in a hopper, counts the sheets, and sends them to a stacker unit. More specifically, it relates to a paper counting device improved to prevent noise and paper jams generated during paper conveyance. Background technique [0002] In the past, the following paper counting device is known, that is, uniformly stores paper (banknotes, etc.) of different types (currency types, etc.) A paper counting device that counts and displays the number of sheets and the total number of sheets (for banknotes, the number of sheets and the total amount of each currency type) and the like (for example, refer to Japanese Patent Application Laid-Open No. 2003-178348). [0003] figure 1 It is an explanatory diagram schematically showing the internal structure of a general sheet counting device. exist figure 1 Among them, the paper counting device 1 has a storage unit 3 for st...

Problems solved by technology

[0009] However, the above-mentioned conventional paper counting device 1 is not configured to prevent entry of thin hard foreign objects (coins, etc.) other than paper.

In addition, since the shape of the conveying path 6 is substantially linear, foreign objects such as coins that are fed out to the conveying path 6 reach the counting / identifying sensor 8d, and there is a possibility of damaging them.

Since the counting / recognition sensor 8d requires high precision compared with the inclination sensors 8a, 8b, and 8c, even small flaws tend to affect its accuracy, and since it is an expensive part, there is a replacement cost rising issue
