Abstract

Bundled signatures are put on a first group of conveyer belts which convey a signature bundle onto a lapping table. A pair of side conveyer belts is arranged on the lapping table at intervals so as to singly and forwards bend the signatures into a bow shape when the signatures are in contact with the side conveyer belts; therefore, each signature is separated from other signatures of the signature bundle. A third group of conveyer belts upwards convey the bent signatures from discharge ends of the side conveyer belts in a lapping mode.

Description

Apparatus and method for converting bundled signatures to shingled stream

The present invention relates to process the sheeting that folded, particularly relate to the such material of the folding and sticking (sticker) of receive stacking and folding and sticking is supplied to successively the apparatus and method of another location.

Printing industry is extensive use of various machines the monochromatic paper that takes off from parent roll paper is transformed into complete magazine and book.However, still keep some manual operationss in this process, these manual expenses are usually very high, and can be because human factor produces mistake in whole printing process.

Service speed and efficient for the production of the modern printing machine of magazine are very high, and usually link together in a piece of paper printing several pages, this paper is normally folded in printing machine.The paper of this folding mistake often combines with other paper that folded, and but whether folded regardless of paper, we are this products known as folding and sticking.The output product of these printer is piled up usually or is bundled into bundle.Along with each formation that contains folding and sticking pile or the bundle of folding and sticking, will produce a large amount of folding and sticking piles or bundle, wherein every folding and sticking is normally through the folding paper of one or many, to consist of several pages an of magazine.

This folding and sticking pile or bundle are transported to gathers leaves of a book and assembling machine, and these machines take out each folding and sticking from folding and sticking pile or bundle, and with suitable order they are combined, and then their bindings is got up and makes a complete magazine.Usually, folding and sticking pile or bundle are placed in the hopper of relevant final processing machine (as gathering leaves of a book/assembling machine), and must guarantee folding and sticking is supplied in each hopper of machine, to make final product.Before being placed on folding and sticking in the hopper, folding and sticking pile or bundle must be broken into folding and sticking stream, in this folding and sticking stream, folding and sticking is in the lapping state each other.

It is not gratifying utilizing artificial batch (-type) ground to load big folding and sticking bundle to hopper, and its reason is to fall into the normal operating that impact that the folding and sticking bundle of hopper produces can be disturbed continuous mechanism of paper.Yet, if attempt by hand folding and sticking bundle to be fed on a small quantity in the hopper and avoid the problems referred to above, just need to resupply continually operation, will greatly increase the weight of the manual work amount thus.In addition, the occupation of land amount for the machine that makes this operating process automation strictly limits usually.

In addition, prepare in order to become magazine or book to binding, workman's need supply to the folding and sticking bundle of some in the hopper repeatedly by hand, can cause workman's somatic damage and heavy burden like this.The workman must mention big folding and sticking bundle, brandishes arm folding and sticking bundle is put on the edge, and rock folding and sticking bundle and make it to pack into and by on the position of described hopper to eliminate the adherent phenomenon between the folding and sticking, then folding and sticking bundle to be put into.Along with repeatedly carrying out this action, the massive folding and sticking bundle of the every less important processing of workman, the so final workman's of making health comes to harm, so that disability.Therefore, the present invention just attempts to alleviate this existing problem.

The folding and sticking bundle that is used for storing folding and sticking compactly is often by long-time compacting, and printing ink just is easy to paper products are sticked together, and this phenomenon is called " page sticking ".The page sticking phenomenon can hinder and gather leaves of a book/efficient operation of assembling machine.But it is believed that the present machine for folding and sticking bundle being transformed into the folding and sticking stream of lapping can't solve this page sticking problem up hill and dale.

Another difficult problem that need to overcome is, when a piece of paper when other a piece of paper slides, the friction of generation is easy to open the outside folding of folding and sticking.When the phenomenon that this being referred to as " pull out " occurring, folding and sticking just is unsuitable for having used, unless the operator returns to it initial folded state by hand.Only folding when once allowing other three limit open wide when the folding and sticking of making, present equipment will be subjected to pulling out having a strong impact on of phenomenon.

Existing folding and sticking stream automatic sheet feeder utilizes pressure air to make folding and sticking separation and lubricated to folding and sticking usually, so that they are supplied to forward in hopper and the assembling machine.In order to eliminate the page sticking problem of folding and sticking, just must operate with a large amount of pressure-airs this separator, therefore easily understand, thisly come energy-producing mode to improve air pressure, for energy to obtain and make to say all be quite expensive.

As can be known, the present invention proposes a kind of apparatus and method for folding and sticking bundle being transformed into the folding and sticking stream of lapping from each purpose of the present invention and feature, this device can reduce to minimum with processing folding and sticking bundle and the required manual work amount of folding and sticking bundle itself.

Another object of the present invention is to propose so a kind of apparatus and method, and it can provide the folding and sticking stream of lapping as required continuously to the hopper of final processing machine.

The 3rd purpose of the present invention provides so a kind of apparatus and method, and it can be separated into single folding and sticking to folding and sticking bundle automatically He effectively.

The 4th purpose of the present invention provides a kind of device that occupation of land can be reduced to minimum.

The 5th purpose of the present invention provides so a kind of apparatus and method, and when being divided into the folding and sticking stream of lapping by folding and sticking bundle, it can be eliminated or reduce significantly friction between the folding and sticking.

The 6th purpose of the present invention provides so a kind of device, and it can be for folding and sticking bundle provides an easily loading height, is provided as simultaneously folding and sticking stream to be supplied in the pocket of final processing machine or the hopper and it is risen to the ability of suitable height.
