関する。[Detailed description of the invention] The present invention is a sheet that transports the continuous sheet, etc. between a supply source of the sheet, etc. and a molding machine that performs the forming, when performing vacuum forming or pressure forming of the continuous sheet, etc. The present invention relates to a conveying device such as a paper sheet, etc., and particularly relates to an improvement of a clip that holds both edges of a sheet or the like in the width direction.

To explain with a diagram, a lever 5 that swings as shown by a chain line 4 with a rotating shaft 3 as a fulcrum is provided on a clip stand 2 connected to a conveyor chain 1, and an upper clip 6 is attached to the lever 5.
a is attached, the spring holder (lower) 7 attached to the clip base 2 and the spring holder (upper) installed on the lever 5
A spring 9 is provided between the clip 6 and the clip 8 to pinch the edge of the seat 10, etc., while a cam or the like (not shown) pushes the bearing 11 from the direction of arrow B, thereby tilting the clip 6 as shown by the chain line 4. It is designed to perform an opening action.

なる。 However, the clip in the conventional device has a large thickness L of the clip base 2 due to the positional relationship between the spring holder (lower) 7 and the sheet clip part, and cannot be easily manufactured by bending steel materials, etc., and has a heavy weight. Since it is manufactured from lightweight aluminum alloy plate or aluminum casting, both processing and material costs are high.

もその反作用を受けねじれ力を受け、チエンの寿
命を短かくする等のトラブルがある。 Additionally, although 400 to 1000 clips are usually used and aluminum alloy is used, which is light in weight, the mass of the material is large, so the clips are still heavy. The heavy weight not only increases the size of the motor for driving the chain, but also increases the tension of the chain, which is very inconvenient. Conventionally, the clip always acts in a closing manner due to the spring, so when holding the edge of the sheet etc.
As shown in the figure, clip 12 connects to sprocket 13.
The sheet, etc. 10 rotates as shown by the arrow 14 along the arrow 14, and at the point when it shifts to linear motion (the point indicated by arrow A in FIG. 2), the sheet, etc.
Therefore, when the clip 12, which has been closed until now, pinches the sheet, etc., the bearing portion 11 is pushed from the direction of the arrow B shown in FIG. 1 by the guide (not shown) at the point A. and open the clip as shown by the dashed line 4 in Figure 1.
Then, the clip 12 that has passed through the guide closes again, pinches the seat, etc. 10, and moves from the linear motion part, that is, the linear motion of the sprocket at the opposite end to the sprocket 13 (not shown) to the rotational motion. , are beginning to move. Therefore, while the clip 12 is open, that is, during rotational movement on the sprocket, the guide is constantly subjected to force, which may cause damage or wear. The manufacturing operation is difficult because it serves as a guide for the next curve, and the chain is also subjected to twisting force due to the reaction, causing problems such as shortening the life of the chain.
本考案は従来装置にある欠点、即ちクリツプの

の搬送装置を提供することである。 The present invention eliminates the disadvantages of conventional devices, namely the high cost of processing the clips and the high material costs, as well as the many problems in terms of weight and operation.
It has a simple structure, can be made at low cost, and is light in weight.
Moreover, it is an object of the present invention to provide a conveying device for sheets and the like that is equipped with a clip that is easy to operate.

になつている。 Next, one embodiment of the present invention will be explained with reference to FIGS. 3 and 4. Reference numeral 21 denotes a clip base 2 manufactured by punching and bending a steel plate using a conveyor chain.
2 is installed. Reference numeral 23 denotes an upper clip, which is made of a steel plate like the clip base 22, and is able to swing from side to side about a rotating shaft 24 attached to the clip base 22 as a fulcrum, and when tilted to one side, the clip base 22 The edge of the sheet, etc. 26 is held between it and a lower clip 25 provided at the tip, and when it falls to the other side, the edge of the sheet, etc. 26 is opened. A spring 29 is provided between the clip base 22 and the upper clip 23 via a spring receiver 27 on the clip base 22 and a spring receiver 28 on the upper grip.
The straight line connecting between 7 and 28 is the upper grip 2.
When moving from the closing operation to the opening operation in No. 3, or vice versa, when changing from the opening operation to the closing operation, the rotation axis 24 is transversely crossed in the transverse cross-sectional direction. That is, when the spring 23 reaches its maximum extension state, the straight line D connecting the spring receivers 27 and 28 coincides with the extension line C connecting the spring receiver 27 and the center of the rotating shaft 24, and the opening/closing operation is performed by the spring. It is now performed at the dead center of the extended state.

つている。 Next, a sheet conveying device using a clip 23 according to the present invention will be explained with reference to FIGS. The clip 23 also moves according to the sprocket 21, and the clip 23, which has been moving on the sprocket 31 in the open state (indicated by the chain line in FIG. 3), changes from rotational motion to linear motion, as shown in FIG. In the moving area, it is pushed by the guide 30 attached to the fixed part 32, and moves from the position of the chain line part 23a shown in FIG. ing.
前記ガイド30は軸33に回転自在に取付られ

押すようになつている。 The guide 30 is a disc rotatably attached to a shaft 33, and is adapted to push against the clip 23 from a substantially perpendicular direction.

スプロケツト31に達するようになつている。 The clip 23 holding the sheet, etc. 26 moves in a straight line, and as the sheet, etc. 26 travels, it reaches a sprocket at the opposite end of the sprocket 31 (not shown), and there, it moves to a guide 30a shown by a chain line in FIG. When pressed, the clip 23 opens and releases the seat 26, and while it remains open, it moves along the sprocket (not shown) and moves linearly again (lower straight section in the figure). , to reach the aforementioned sprocket 31.
以上説明したように、本考案によるクリツプを
使うことにより、シート搬送装置は前述のような

つたガイドを必要とせず、第5図および第6図に
示すように円板状のガイド30でクリツプを押付
るだけでよい。 As explained above, by using the clip according to the present invention, the sheet conveying device can eliminate the above-mentioned conventional drawbacks, and since it is a steel plate,
Not only is the mass smaller and the weight lighter,
The material cost is also cheaper compared to aluminum alloy. In addition, when opening and closing the clip, once the guide 30 pushes the upper clip 23, it remains in the open or closed direction, so the twisting of the chain 21 that conventionally occurred, and when pushing the clip 23, can be avoided. This eliminates the need for an unnecessary force on the guide 30 of the guide 30, eliminates the need for a guide with a complicated cubic curve as in the conventional case, and eliminates the need for a guide with a complicated cubic curve as shown in FIGS. 5 and 6. All you have to do is press the clip using the guide 30.
更に、何等かの原因によりクリツプがシート等
を把持しきれないような力がクリツプに負荷され
たとき、スプリングによるシート把持力を上回つ
た時点でクリツプは開いてしまい、無理なシート
等の搬送が行われないようになつている。 Furthermore, if for some reason a force is applied to the clip that makes it difficult for the clip to grip the sheet, etc., the clip will open when the force exceeds the sheet gripping force provided by the spring, causing the unreasonable conveyance of the sheet, etc. is no longer being done.
