To cut and separate a sheet of molded products to be cut, which is formed by connecting a sheet of foamed synthetic resin in a grid pattern, into individual molded products, the mouth-shaped frame must be closed.1. That is, with the abutment plate closed and positioned opposite the base of the mouth-shaped frame, the molding to be cut is made to a height that allows it to pass between the support parts provided on the upper and lower inner surfaces of the mouth-shaped frame. 1. Stack the product sheets and use the appropriate luck. It is automatically or manually placed on the base by means of a clamping means, and the driving/υ1 source of the pressing part which can be moved and moved from one end of the base to the other end is driven, and the pressing part drives the stacked state. Press the molded product sheet to be cut toward the other end of the base until the row of cut molded products at the tip passes through the mouth-shaped frame and comes into contact with or comes close to the contact plate, and press the sheet to be cut at the tip. If the molded product rows come into contact with each other or come close to each other, the cylinder is driven from above to the molded product row that is in front of the tip of the molded product row to be cut in the stacked molded product sheets to be cut. It is pressed by the pressing part in front of the other end of the platform, and the row of molded products to be cut at the tip is pressed and clamped from above and below by driving the supporting parts provided on the upper and lower inner surfaces of the mouth-shaped frame by driving means such as cylinders. . Next, the abutting part is rotated or moved downward to avoid the rotation range of the mouth-shaped frame, and at the same time, the mouth-shaped frame is moved to face the base around the rotation axis provided on the side of the frame. By rotating it toward the side, the row of molded products to be cut at the tip is pulled toward the side opposite the base, and the row of molded products to be cut at the tip is pulled along the discontinuous cuts between the rows of molded products to be cut. The molded product is cut and separated from the sheet body of the molded product to be cut. At the end of the rotation range, when the frame is tilted or rolled over, the upper and lower support parts within the frame are simultaneously expanded to release the clamped row of molded products to be cut, thereby passing the receiver to the next process. be.

The row of molded products to be cut that has been passed to the next process is further cut and separated using other separating equipment or manually.The molded products after separation are then packaged using packaging equipment or manually. When the individual molded products are cut and stacked, they are packaged as is.

Furthermore, by returning the mouth-shaped frame and the contact plate to their original positions and repeating the above-mentioned operations, it is possible to sequentially cut and separate the sheet of molded products to be cut into a row of molded products to be cut or into individual molded products. .

(Example) Hereinafter, the preparation of the foamed synthetic resin molded product of the present invention will be explained.
Further details are disclosed in the accompanying drawings.

The foamed synthetic resin molded product used in the present invention is produced by, for example, heating a heated thermoplastic foamed resin sheet in a molding space of a mold.
A large number of trays and other molded products are molded by multiple mold clamping steps.
The side edges of a single sheet formed by connecting a large number of molded products to be cut in this way are trimmed, A sheet B of the molded product to be cut is used, in which discontinuous cuts are made between each molded product using a Thomson blade, and the corner portions of each molded product are punched into a substantially star shape in order to chamfer each other.

The main body 1 of the separation bath 11 device A has a base 2 sized to hold the molded product sheets B to be cut in a stacked state.
A pressing part 3 movable toward the other end of the base 2 is provided in relation to a drive source such as a motor, and in front of the other end of the base 2, a pressing part 3 movable toward the other end is provided. A pressing part 5 that presses a row of molded products to be cut from above in front of the row of molded products to be cut 4 at the tip in a direction perpendicular to the direction of the molded products to be cut (see) B is attached to the main body l to press the molded products in the stacked state. The cut and formed crystal sheet B is provided in relation to a cylinder 7 fixed to a U-shaped frame member 6 formed to cover the exterior, and the other end of the base 2 has a rotation axis on one side. When closing, the molded product row 4 at the tip adjacent to the molded product row 4 to be cut, which is arranged parallel to the frame material 6 and pressed by the pressing part 5 in front of the other end of the base 2, is held in the state. Exterior mouth-shaped frame 8
has been established. Figure 1 (b) shows this mouth-shaped frame 8.
A frame body 26 is formed in the shape of an opening to which an elastic member 13 for cushioning is attached at an appropriate position on the contact surface of the base 2, and the rotation mechanism of the frame body 26 is An upper support part 9 and a lower support part 10 for holding the tips of the rows of molded products to be cut 4 are placed opposite each other on the upper and lower inner surfaces thereof, and each is provided in relation to a driving means such as a cylinder IL 11 so as to be movable up and down. The maximum distance between the lower support parts 9 and 10 is set so that the tip of the molded product row 4 to be cut, which is press-transferred from the base 2, has a size and position that allows it to pass through. One side of the 1-shaped frame 8, in the case shown, the left side of the room 8 supports the weight of the frame 8 and serves as the center of rotation. Mounting with the shaft hole 25 can be done by providing the parts 27 at the top and bottom, and by fixing the shaft hole 25 to the rotation shaft 29 of the rotation drive source 28 located near the side of the base 2. , the frame 8 is configured to be able to rotate by a certain angle toward the side facing the base 2 as the rotation shaft 29 rotates.The rotation angle of this plane is approximately 90'' in the illustration, but The method is not limited to this, as long as it is possible to separate the rows of molded products 4 to be cut, which will be described later.

In addition, on the side of the opening-shaped frame 8 opposite to the base 2, there is provided a plate for regulating the advancement of the stacked molded products B) to be cut, which are pushed out from the base 2 by a certain amount at a time by the pressing part 3. The abutment plates 14.14 are provided at positions where the row of molded products to be cut at the leading end can come into contact with or come close to when the row of molded products to be cut at the leading end is clamped within the frame 8. Rotating parts 30, 30 connected to a drive source (not shown) are provided at the lower ends of each of the contact plates 14, 14, so that when the mouth-shaped frame 8 rotates, It is configured to avoid the rotation range. In the illustrated example, two abutment plates are installed at a constant interval, but the number and position of the abutment plates are not limited to this, and the above-mentioned avoidance method also does not rely on rotation. It is also possible to move the abutment plates 14, 14 downward using a drive source such as the above.

Therefore, in this device A, the frame 8 rotates toward the opposite side of the base 2 while holding the molded product row 4 at the tip between the upper and lower support parts 9 and 10 on the upper and lower inner surfaces, thereby cutting the tip. A row of molded products to be cut 4 is a stacked molded product sheet 1 to be cut.
-B, and the molded product sheet B to be cut is cut and separated along the discontinuous cuts made in advance on the Thomson blade.

In the figure, reference numeral 15 denotes a mouth-shaped frame 8 when the stacked molded product sheets B on the base 2 are pressed by the pressing section 3.

Reference numeral 16 denotes guides attached to both sides of a frame member 6 provided to attach the pressing portion 5 in front of the other end of the base 2.

The guide 16 may be attached to the frame member 6 with screws or the like so that the dimension between the opposing inner surfaces of the guide 16 and 16 can be set as appropriate.

In order to make the pressing part 3 movable from one end of the base 2 to the other end, in the embodiment, as shown in FIG. death,
Two openings 19.19 are provided on the base 2 surface in the direction of movement of the pressing part 3, and the rod 20.20 exposed from the openings 19.19 onto the base 2 surface is connected to the chain 17. 17 is attached to a rod 18 horizontally suspended between the rods 20 and 20, and a pressing portion 3 is attached to the rod 20 and 20.

By linking the chain 17.17 to a drive source such as a motor and making it reversible, the pressing section 3 can be moved from one end of the base 2 to the other end.

In addition, in the illustration, the pressing surface 3' of the suppressing part 3 is such that on one end side of the base 2, the surface of the base 2 and the pressing surface 3' of the pressing part 3 are in contact with the road surface, as shown by the dashed line. By doing so, it becomes easy to place the stacked molded product sheets 1-B to be cut on the base 2.

21 in the figure are guide pins inserted into small holes 22 provided in the frame member 6 and the mouth-shaped frame 8.

Regarding the shape of the upper support part 9, when stacking the molded product sheets B to be cut with the opening surface facing upward, if the upper support part 9 is formed to approximately match the shape of the accommodating part, the clamping force can be applied to the sheets B.
It is effective in preventing damage to the sheet B because it can be uniformly dispersed over the entire surface of the sheet B.

In order to cut and separate stacked molded product sheets B to be cut into rows of cut molded products 4 using such a separating device A,
The opening-shaped frame 8 is placed in a state parallel to the frame member 6, that is, in a closed state, and the bracket abutting plates 14, 14 are raised up on the opposite side of the base 2 of the opening-shaped frame 8.
The molded product sheets B to be cut are stacked at a height that allows them to pass between the upper and lower support parts 9 and 10 provided on the upper and lower inner surfaces of the holder, and the pressing surface 3' of the pressing part 3 is made the surface of the base 2. In this state, the base 2 is moved automatically or manually using a transportation means (not shown) as appropriate.
A drive source such as a motor of the pressing section 3 placed on the base 2 and movable from one end to the other end is driven, and the pressing section 3 moves the stacked molded products to be cut B. In the direction C-+ toward the other end of the base 2, the tip-cut molded product row 4 is connected to the abutting plate 1.
4.14, and if the row of molded products to be cut 4 at the tip contacts or comes close to the contact plates 14, 14, the sheet of molded products to be cut B in the stacked state is pressed. The cylinder 7 is driven from above to press the row 4 of molded products to be cut, which is in front of the molded product row 4 at the tip, by the pressing part 5 in front of the other end of the base 2, and the molded product to be cut at the tip is pressed. The upper and lower support parts 9 and 10 with the tabs 4 provided on the upper and lower inner surfaces of the mouth-shaped frame 8 are connected to the cylinder IL 1.
1 and clamp it from above and below.

Next, the contact plate 14.14 is rotated to a horizontal position opposite to the base 2 to avoid the rotation range of the mouth-shaped frame 8, and then the rotation drive source 28 is driven to rotate the mouth-shaped frame. 8 is rotated by a certain angle about the rotation axis 29 toward the side opposite to the base 2. Due to this rotation, the row of molded products to be cut 4 at the tip is pulled, and the discontinuous part that is the boundary between the main body of the molded product sheet B to be cut near the free end side of the mouth-shaped frame 8 and the row of molded products to be cut at the tip is pulled. A tensile force is concentrated at the cut, and the molded product row 4 at the tip is cut and separated from the main body of the cut molded product sheet T3 along this cut.

In particular, the molded product sheet B to be cut used in this example is the third
As shown in the figure, the corners of each molded product 24 are chamfered, and each row of molded products to be cut 4 at the left and right ends of the molded product sheet 1-B is cut.
Since a notch is provided in between, cutting and separation of the rows 4 of molded products to be cut is made easier. In addition, the rotation angle of the mouth-shaped frame at this time is approximately 90° in the illustration, but if it is possible to separate the molded product row 4 to be cut, this angle may be set appropriately, and the rotation angle of the mouth-shaped frame The position of the rotation shaft provided on one side is not limited to the left and right sides, but may be provided on the top and bottom sides as long as it is possible to support the row of molded products to be cut 4 held in the mouth-shaped frame 8 after separation.

In this way, the molded products row 4 is cut and separated by the rotational movement of the mouth-shaped frame 8, and the row of molded products to be cut 4 reaches the end of the rotation range as the mouth-shaped frame 8 moves while being held in the mouth-shaped frame 8. Immediately after being transported to the position, the receiver is transferred to a separating device or a manual work space provided as appropriate to further separate the row of molded products 4 to be cut into individual molded products, and the method of transferring the receiver is not shown in the figure. However, for example, the rotation drive source 28 itself for rotating the opening-shaped frame 8 may be related to another rotation drive device, etc., so that the opening-shaped frame 8 can be tilted at the end position of the rotation range. This is accomplished by turning it over on its side. After passing through the final step of separating the molded product 24 (not shown), the molded product 24 discharged to the outside may be appropriately packaged using a packaging device or manually. By repeating the above-mentioned operations in this manner, the stacked molded product sheets B to be cut can be cut and separated into individual molded product rows.

The device for separating foamed synthetic resin molded products configured as described above cuts and separates the molded products to be cut by pulling the row of molded products to be cut 4 against the molded product to be cut sheet 1-B, and therefore does not require the use of any particular cutter. This has the effect of eliminating the need to periodically replace the blade and making maintenance extremely simple. Further, the separation process and the transfer of the row of molded products to be cut 4 to the next process can also be used as a transfer operation, and the apparatus can be simplified.

〔Effect of the invention〕
