Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding device effective for use in an automatic processing machine for folding a laminated laver piece such as raw laver in a strap-on packaging.

2. Description of the Related Art Conventionally, when stacking thin leaf pieces such as paper materials and folding them into folds, especially in the case of band wrapping of raw seaweed, it has been performed manually. In other words, the procedure was to stack two sets of a pile of raw seaweed (10 sheets) on top of each other with their half areas overlapped, and then turn over and overlap the remaining half areas of both wings.

Under the present circumstances, the emergence of a folding folder by the automatic processing of the above-mentioned laminated laver pieces is strongly desired.

The problem to be solved by the invention. However, the work using a folding plate that rotates 180 ° like the folding mechanism that is generally used in the past, because the object to be treated is a laminate of thin leaf pieces, To do all at once requires a relatively strong drive, and
Since the turning amount is large, it is difficult to increase the speed, and especially when it is used for folding a piece of raw seaweed, this raw seaweed is relatively strong and brittle, so there is a risk that it will break due to sudden folding. Therefore, this kind of conventional means is difficult to apply.

Therefore, an object of the present invention is to develop an automatic folding device for laminated laver pieces that can meet such requirements.

Means for Solving the Problems To this end, according to the present invention, a series of transfer paths for delivering two sets of laminated laver pieces stacked in a predetermined amount in a partially superposed state are formed.

Along this transfer path, the first processing stage in which the folding guides made of twisted pieces that gradually deform from the horizontal state to the vertical state with one side of the strip plate as the fulcrum are installed on both sides, and the sequential inclination from the upright position And a second processing stage in which folding devices, each of which is composed of a belt wound around several synchronous rotation rollers reaching a horizontal position, are also arranged on both sides of the transfer path.

Further, the pair of folding devices are configured such that the arrangement positions on both sides of the transfer path are slightly shifted back and forth, and the pair of folding devices work alternately on the moving piece to be processed.

Action By the folding guides, which are twisted pieces arranged on both sides of the transfer path of the piece to be processed, the piece is gradually raised from its horizontal state to its vertical state. At this time, the sandwiching roller group, which sandwiches the overlapping portions of the pieces in the vertical direction, acts as the pressing function of the pieces and a stable feeding function section.

In the folding device for the following transfer path, since a large number of rollers are gradually inclined, these rollers act on both blades of the leaf piece to be treated which has been erected upright, and the blades are inwardly moved along the inclination of the rollers. Due to the structure in which the installation positions are shifted back and forth on both sides of the transfer path, the folding of both blades is folded from one side of these blades first, and then the other blade portion is folded.

Then, this processing operation is continuously performed on the leaf pieces to be processed placed on the workbench, and after being sequentially folded, it is sent out to the next band strapping packaging process or the like.

Embodiment FIG. 1 and FIG. 2 are a plan view and a side view showing an embodiment of a raw laver folding device according to the present invention.
In the above, two sets of one scholar (10 layers) of raw seaweed leaf pieces (hereinafter, abbreviated as a shackle piece) are inserted with intervening paper 3 sandwiched between each shackle piece 2, 2. The two blades are left and the central portion is overlapped (see the upper chain line in FIG. 3) and placed. At this mounting position, a chain belt conveyor device 4 (see FIG. 3) with a feed piece for the knuckle pieces 2 and 2 is installed, and it is installed side by side with a part of the transfer path by the device 4 and A pair of nipping roller groups 5a and 5b are arranged.

The sandwiching roller groups 5a and 5b are provided with belts 7a or 7b that are respectively wound around drive wheels 6a or 6b connected to the drive system 6.
Thus, the feeding operation by synchronous rotation is restricted together with the conveyor device 4. In particular, as shown in FIG. 4, the nipping roller group 5a located at the upper part is attached to the supporting rod 9 which is raised from the machine base 8 through the fine adjustment mechanism 10 including bolts, and the lower part of the lower nipping roller group 5a is installed.

Following the arrangement of the sandwiching roller groups 5a and 5b, the transfer path is
Another intervening paper 13a or a device 13 for delivering the desiccant onto the transfer path is arranged.

14a and 14b are folding devices, each of which is composed of several rollers 15a to 15g whose angles facing the transfer path are gradually changed. These rollers 15a to 15g are hooked on a pulley 16a connected to the drive system 6. The belt 16 is synchronously driven. That is, the main part of these rollers 15a to 15g is, as shown in FIGS. 6a to 6e, first, the roller 15a is arranged perpendicularly to its side edge with respect to the transfer path.
The following roller 15b is arranged with a slight inclination so as to be crowned on the transfer path, and the following rollers 15c and 15d are arranged with an increased inclination facing the transfer path, and the roller 15e is in a horizontal state parallel to the transfer path surface. It is located in. And
Both folding devices 14a and 1 having such a roller structure.
When installing 4b on both sides of the transfer path,
In order to prevent 15a to 15e from colliding with each other on the track, their positions are offset from each other.

In addition, in the transfer path on which the folding devices 14a and 14b are installed, guides are provided at both ends on the road side, which are floated from the road surface by an amount corresponding to the thickness of the hinge pieces 2 and 2 to be transferred, by a bridge strut 17 straddling the path. Rails 18 and 18 are arranged respectively.

Further, the pressing piece 19 is provided on the transfer path passing through these installation positions.
(See FIG. 7) is provided, and a pressing rail 21 which replaces the pressing piece 19 is exposed in the middle of the transfer path by a bridge strut 20 arranged in the delivery area.
