Description

[Detailed Description of the Invention] (Industrial field of application) The present invention is a sheet shape that can be handled as a pattern, a signature, or other single piece in which a box is developed in a predetermined position such as a pocket of a sucking machine or a collator. The present invention relates to a device for sequentially supplying products.

(Prior Art) Conventionally, as a supply device of this type, for example, JP-A-61-757
The one shown in Japanese Patent Publication No. 52 is known.

FIG. 6 is a schematic view of such a conventional device, in which the sheet-shaped laminate (A) placed on the receiving member (2a) of the lifter (2) is an auxiliary lifter in the process of being raised. (3) is moved up, and is sequentially sent out from the uppermost sheet-like object by the delivery wheel (4), and a pair of endless belts (6),
It is sandwiched between (7) and fed into a predetermined position (5) such as a pocket. FIG. 7 shows a process in which the lifter-shaped material of the lifter (2) is transferred to a conveying device composed of a pair of endless belts. In the moving process, the sheet-shaped material is loosened and inserted between the belts. And around a relatively large diameter wheel (8), each sheet is turned upside down. pocket
When a predetermined amount is fed into (5), the operation is stopped by an appropriate sensor, and the supply of the sheet-shaped material is stopped.

(Problems to be solved by the invention) In the conventional device, as shown in FIG. 7, since the wheel (8) for hanging the pair of belts together is near the laminate (A), the sheet-like material is If there is a certain degree of rigidity, when the front edge of a sheet (A1) sent out by the delivery wheel (4) reaches the lower end of the wheel (8) and is sandwiched between the belts, the sheet As indicated by the arrow (F), a downward warping force acts on the rear end of the rear end and pushes down the next sheet-like material (A2) on the laminated body below it. Therefore, it becomes a resistance when the sheet-like material is sent out, slows down the delivery speed and hinders the sheet from being sent out straight, and in some cases, the front edge of the sheet-like material is sandwiched between the belts in a state where it is bent downward. There was a point.

An object of the present invention is to solve the above-mentioned problems, and therefore to provide a sheet-like material feeding device capable of sequentially and appropriately delivering a previous sheet-like object without pushing down the next sheet-like object. That is.

(Means for Solving Problems) The features that characterize the present invention are a lifter that raises stacked sheets, and a delivery wheel (4) that sequentially delivers the sheets on the lifter from the top. , A pair of endless belts that sandwich a sheet-like object sent out by the sending wheel and turn it upside down to send it to a predetermined position
A common wheel including (6) and (7), in which the uppermost sheet-shaped material of the sheet-shaped material laminated body is on the upper side in the direction in which it is fed by the delivery wheel, and the pair of endless belts are hung together ( 8) is provided, and one of the rollers (11) for hanging one of the endless belts and one of the rollers (12) for hanging the other endless belt are arranged in a vertical relationship apart from each other and the sheet-like material is laminated. It is installed at a position close to the delivery side of the uppermost part of the body, and between the outer peripheral position where the rollers start to separate from the respective endless belts and the outer peripheral position where the rollers start contacting with the pair of endless belts. Delivery of sheets from a stack of sheets is such that their endless belts extend linearly and do not affect the delivery of subsequent sheets when they reach the circumference of the common wheel. In the direction That is approximately equal intervals in the size of the sheet is that are provided.

(Operation of the means) When the front edge of the sheet-shaped product reaches the lower end of the wheel (8) and is sandwiched between the belts, the rear end of the sheet is separated from the position of the laminated body. It does not exert any pushing down force and thus does not interfere with the delivery by the delivery wheel (4).

(Embodiment) Next, an embodiment of the present invention will be described with reference to the drawings. 1 to 4 show an example of the present invention,
As shown in the figure, this device also has a lifter (2) that is lifted by a receiving member (2a) as in the conventional case, where a stack (A) of sheet-like objects sent to the tip of an infeed conveyor (1) as a support is sent. ), And an auxiliary lifter (3) that receives the stack on the lifter during transfer.
And a delivery wheel (4) that sequentially delivers the uppermost sheet-like material on the lifter, and a pair of sheets that sandwich the sheet-like material delivered by the wheel (4) between them and send it to a predetermined position such as a pocket (5). It is composed of a conveying device including endless belts (6) and (7). Then, on the delivery side of the uppermost part of the laminated body on the lifter, there is a wheel (8), preferably a relatively large diameter, on which the pair of belts (6) and (7) are hung together, and by turning around this wheel, the seat is formed. The objects are turned upside down. A friction wheel or a vacuum wheel is preferably used as the delivery wheel (4). Further, the pocket (5) has an appropriate sensor (9) so that the operation is stopped when a predetermined amount is inserted.

As shown in FIG. 1, the characteristic feature of the sheet-like material supplying device is the transfer mechanism from the lifter (2) to the conveying device. That is, the wheel (8) on which the pair of endless belts (6) and (7) are hung together in an overlapped state is located above the sheet-shaped article stack (A) and is located above the sheet-shaped article stack (A). Installed at a distance. And, between the lower end of the wheel (8) and the upper end of the laminate, a pair of belts (6), (7) extend in a vertical relationship with each other, and therefore one of the rollers of each belt, that is, the illustrated In the example, one roller (11) for hanging the belt (6) and one roller (12) for hanging the belt (7) are in the vicinity of the delivery side at the top of the laminate.

The rollers (11) and (12) placed near the top of the stack are arranged in a vertical relationship as shown, with a wheel (4) between them.
The sheet-like material sent in is sent in. The distance between the lower end of the wheel (8) and the delivery side of the top of the stack is small, but the size of the sheet in the delivery direction
(l) or slightly smaller, so that the rollers (11) and (12) start contacting the pair of endless belts on the common wheel (8) with the outer peripheral position where they start to separate from their respective endless belts. An interval approximately equal to the size of the sheet-shaped article in the sheet-shaped article delivery direction from the sheet-shaped article laminate is provided between the outer peripheral position, and between them, as is clear from FIGS. 1 and 2, Endless belt (6),
(7) extends linearly. The front edge of the sheet-like material sent out by the wheel (4) reaches the periphery of the lower end of the wheel (8), that is, the outer peripheral position where it comes into contact with the pair of endless belts (6) and (7), and is sandwiched between the belts. At that time, the trailing edge of the sheet-like material is located at a position separated from the laminate.

In operation, the rising sheet, which is supported by the lifter (2) or the auxiliary lifter (3), is lifted by the delivery wheel (4), preferably partially overlapped, in succession with the rollers (11) and (12). ) Between the belts (6), (7)
After a certain amount of movement between the wheels (8), reaching the lower end of the wheel (8) and being sandwiched between the belts, around the wheel (8),
Upside down, pockets sandwiched between belts
Sent to (5). If you turn upside down like this,
Since the previous sheet is below the subsequent sheet, it can be transported at high speed.

With this feeder, as shown in FIG.
The front edge of (A1) reaches the lower edge of the wheel (8) and slightly
When starting to rotate around (8), the rear end is not on the laminate (A) even if the rear end is pushed downward due to the rigidity of the sheet material, and the roller (12) or the belt (7) Because it is above
It acts on the roller (12) or the belt (7) through the front part of the next sheet (A2) and does not act on the laminate (A) on the lifter. Therefore, the delivery of the subsequent sheet-like material is not hindered.

(Effect of the Invention) As described above, according to the present invention, the transfer wheel is completely unraveled during the transfer process, and even if the sheet-like material has rigidity, it does not hinder the transfer action of the transfer wheel, It can be transferred to and supplied to a predetermined position.
