Description

Book thickness detection device

technical field

The invention belongs to the technical field of measuring devices, and particularly relates to a book thickness detection device.

Background technique

During book binding, in order to ensure the binding quality and avoid the occurrence of unqualified products such as missing pages and multiple pages, a detection device should be used before binding to detect and reject unqualified products such as missing pages and multiple pages.

The stapler is a stapler specially used for binding various thin booklets, picture albums, magazines, etc.; generally, two heads are used for binding, and up to four heads can be bound at the same time. The number of machine heads can be selected arbitrarily, and the binding can be completed at one time, whether it is a single-page book or a double-page book. To tie pages is to tie sheets of different page numbers together. The saddle stitcher automatically sends the signature, automatically binds and automatically collects the book after the manual page-laying or the collating machine. The whole process is controlled by the electrical appliance, so the transmission is balanced, safe and reliable. When the number of page numbers is small, manual page folds are often used. However, when the pages are manually folded, due to the need to repeatedly arrange the page numbers, it is very easy to cause more or less folds. When the number of pages is large, a collating machine is used to fold the pages. However, the collation machine also often fails, resulting in more or less page numbers. At the same time, due to the large number of pages, it is not easy to find.

In view of the above technical problems, it is necessary to improve.

The working principle of the present invention is:

Set the detection distance according to the thickness of the book to be bound: Rotate the adjustment dial 17 to make the distance between the upper detection wheel 6 and the lower detection wheel 8 equal to the thickness of the book to be bound. The swing arm 11 is in the horizontal position shown in the figure as a reference, and the distance of the detection block 16 sensed by the digital displacement detector 15 is the detection standard value.

After completing the preliminary adjustment, rotate the detection adjustment handle 10 so that the detection distance between the digital displacement detector 15 and the detection block 16 is greater than the reference value, that is, the distance between the upper detection wheel 6 and the lower detection wheel 8 is smaller than the thickness of the bound book.

During online detection, the book 7 is transported to the upper detection wheel 6 and the lower detection wheel 8 to be clamped. The upper detection wheel 6 is shifted by the servo motor 2 through the reducer 3 to drive the synchronous pulley 4 to rotate, and the upper detection wheel is driven by the synchronous belt 5. 6 Rotate, automatically track the speed of the book, so that the speed of the upper detection wheel 6 is consistent with the speed of the book transmission.
