Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention applies a tension to the peripheral surface of a winding core for flat articles such as carton blanks, packages, newspapers, printed matter, etc. which are discharged in the form of stacking and stacking. The present invention relates to a take-up stacker that is wound up while being held by a holding belt to form a take-up body, is stacked, and is unwound from a stacked take-up body in a subsequent step to sequentially supply the flat articles.

[0002]

2. Description of the Related Art Flat articles discharged at high speed from a manufacturing / processing apparatus such as a punching machine, a printing machine, a folding machine, a bag manufacturing machine or the like are stacked in a manufacturing / processing step or a post-processing step. Then, the stacked flat articles are sequentially supplied to the manufacturing / processing apparatus in the next step.

It is known in the prior art to manufacture manufactured flat articles, such as carton blanks, printed matter, etc., by stacking them, placing them on pallets and combining them to form a transportable unit. To form edge-aligned laminates from flat articles, there are numerous devices that stack flat articles that are individually fed at high speed in front of an abutment to form edge-aligned laminates. Are known. Also, in the case of flat articles that come from the manufacturing and processing equipment and are stacked on the conveyor belt for transport and stacked and placed in a flowing form, these flat articles are divided into appropriate quantities and put together. It is known to push and stack these flat articles with their edges aligned and, optionally, further bound.

In these known stacking machines, the flat articles can only be formed and discharged intermittently, so that the flow of flat articles constantly supplied by the manufacturing and processing equipment must be interrupted for a short time. Therefore, there was the problem of requiring a device to stop the flow of flat articles or to divert it to another laminate forming station. In addition, the operation of collecting the individual laminated bodies into a larger unit suitable for transportation is performed by manually stacking the individual laminated bodies one by one on a pallet or as a set of laminated bodies, or individually on the pallet. There is a problem in that a palletizing device for assembling the above laminated body is required.

Further, the flat articles forming the edge-aligned laminate must be separated for the purpose of supplying them to the next manufacturing and processing apparatus, but also in this case, many manual operations are required. There was a problem. For example, when placing the carton blank bundle on the feeder of the box making machine to put it in the state of being sacked in the next box making process, grasp the carton blank bundle on the pallet by hand and the box making machine has directionality. The carton blanks were placed on the feeder while aligning them so that they face in a predetermined direction.

[0006] Therefore, flat articles such as newspapers, magazines, bags (sacks), bags, etc. discharged from the manufacturing and processing apparatus in a form in which they are gathered on the conveyor belt in an overlapping manner and flow, are stacked as a roll-up body, Alternatively, a device for continuously feeding a flat article from a winding body is conceivable, and is disclosed in Japanese Patent Laid-Open No. 63-2.
It is known from Japanese Patent No. 35249, Japanese Patent Laid-Open No. 2-52852, and the like.

These devices have a winding core for winding a flat article, and a holding belt attached to the winding core and sandwiching the flat article between the winding cores. For example, U.S. Pat. No. 4,532,750 discloses a winding-up type comprising a hollow cylindrical winding core for winding flat articles in an overlapping manner and winding them in a flowing form, and a belt reel for a holding belt disposed inside the winding core. Stackers are well known. FIG. 8 shows a cross-sectional view of a hollow cylindrical winding core and a belt reel for a holding belt arranged inside the winding core. The take-up core is supported by a shaft that extends continuously from the take-up core via a rib, and the belt reel is rotatably supported by this shaft. A drive wheel 2, which is rotatably connected with the belt reel, is also mounted on the shaft, so that the drive wheel 2 can be brought into contact with a friction wheel which is pivotally mounted for rotating the belt reel. As shown in FIG. 8, the winding core is provided with a slot, and the holding belt disposed inside the winding core can be passed through the slot.

The holding belt is always conveyed and supported together with the winding core. A holding belt of the required length is unwound from the belt reel before the flat article is wound, and due to the stacking,
It is wound up on a belt reel arranged outside the winding body.
When the flat belt is rolled up, the holding belt is pulled out from the belt reel and wound around the flat core or the winding core together with the flat article. The unnecessary holding belt portion is left wound around the belt reel.

By the way, the structure of this known winding device is extremely complicated and the manufacturing cost is high. This point is important because a large number of such roll-up type stackers are required especially in the printing industry. Furthermore, this roll-up stacker requires a large space in the direction of the axis extending laterally from the roll. In addition, a unique drive is required to unwind the winding tape from the belt reel, and this drive must additionally drive the winding body.

[0010]

The winding device in the above-mentioned prior art is extremely complicated in structure and is therefore expensive, but the cause is in the method of processing the holding belt wound around the winding core. One of the reasons why the processing of the holding belt is complicated is that the flat article to be stacked will be damaged unless the peripheral surface of the winding core is flat. SUMMARY OF THE INVENTION It is an object of the present invention to provide a roll-up stacker that is simple in structure and inexpensive, without scratching stacking flat articles.

[0011]

The above object is achieved by the present invention described below, that is, a flat article discharged in the form of stacking and stacking is placed on the peripheral surface of a cylindrical winding core by tensioning. It is wound up while being held by a holding belt that has been given and stacked as a winding body, and the flat article that has been stacked is unwound in the next step, gathered in a misaligned state and supplied to the manufacturing and processing device in a flowing form. A stacker, at least a take-up core held by a take-up shaft rotatably supported by the take-up stacker base, and a belt reel supported by the take-up stacker base. And at least one holding belt having one end fixed to the winding core to apply tension to hold the flat article, and
One end of the holding belt is fixed to the peripheral surface of the winding core with a fixing metal fitting, and the surface of the fixing metal fitting is flush with the peripheral surface of the winding core. This is achieved by a take-up stacker in which a recess is formed on the surface at the fixing belt fixing position.

[0012]

According to the present invention, since the one end of the holding belt is fixed to the take-up core by the fixing metal fitting, the cost of the take-up stacker can be reduced. Also, to prevent scratches on stacked flat articles due to the protrusions of the fixing metal fittings, secure the holding belt on the winding core peripheral surface so that the surface of the fixing metal fittings is flush with the peripheral surface of the winding core. This can be prevented by forming the concave portion at the position.
