Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a device for taking out a resin molded product from a mold of a molding device and supplying it to a stacking device for stacking the molded products.

(Prior Art) It is well known that a mold of a resin sheet molding apparatus is provided with a cutting blade for trimming a mouth portion simultaneously with molding. However, the conventional method is to blow the trimmed product from the trimming position at the trimming position to the shutter forming the receiving port of the stacking device by pressing air, or to lower the shaped and trimmed product together with the mold so that the mouth end is on the outlet side. There was a method of rotating the mold so as to face it and projecting the trimming product to the receiving port of the stacking device provided on the outlet side, but both have problems in stability and durability, especially in containers and the like. A molding machine that performs molding and trimming for small resin moldings at the same time encounters the need to stack the trimmed products accurately.

(Problems to be solved by the invention, purpose of the invention) In the case of a device that blows a molded product trimmed at the same time as molding from the trimming position to the shutter that constitutes the receiving port of the stacking device, how much the air amount is adjusted However, the trimming product does not always blow to the same position even if the direction is adjusted, and this requires that the stacker inlet of the stacking device be enlarged, which makes the product originally oriented vertically. The stack by the stacking device is extremely defective because some stacks enter sideways even though they have to enter the stack. Further, in the case of a device that rotates the die in the direction of the stack and stacks the stack, the stacking is reliable, but the precision of meshing the blades of the die is reduced, and the life of the blades is shortened, which is a problem. Therefore, it is a problem that this needs to be solved, which is the purpose of the solution of the present invention.

(Means for Solving the Problems) The device for taking out the product of the molding apparatus and the feeder for the stacking apparatus according to the present invention is moved up and down with respect to the base (9) provided with the cutting blade (25) and the base (10). Cutting blade (25) for the base (9)

(Embodiment) A preferred embodiment of the present invention will be described below.

FIG. 5 shows an example of the resin sheet molding machine 1 to which the present invention is applied. The resin sheet extrusion machine I, the molding apparatus II, and
The stacking device III and the stacking device III are arranged on a line. The resin sheet extruder sends the raw material resin from the hopper 2 to the extrusion cylinder 3 equipped with a screw and heating device, and extrudes the resin sheet C of the required width from the T die 4, and the cooling roll device 5
To the molding apparatus II.

The forming device II is provided with a dancing roll device (not shown) for adjusting the intermittent forming timing of the resin sheet C, and subsequently, the lower base 7 and the ram below the resin sheet C are formed at right angles to the sheet feeding direction. 8 is provided, the upper base 9 is arranged on the upper side, and the lower die 10 is attached to the ram 8. Lower mold 10
Is a female mold for molding a deep cup-shaped product P for coffee or the like, and an inner blade 11 is provided on the outer periphery of the mouth of the mold. A knockout rod 12 that points toward the center of the lower die 10 is fixed to the lower base 7 below the ram 8, and the lower die 10 forms the bottom die as the ram 8 rises to the molding position as shown in FIG. The knockout type pin 13 is provided, and the knockout pin that is almost in contact with the above knockout rod 12 from the knockout type 13
14 is projected downward.

In order to form a bottom ring Pa (FIG. 4) that ensures the retention by the knockout die 13 until the product P is taken out, the knockout die is provided with a peripheral groove 15.

A downward cylinder 21 is attached to the upper base 9, and a rod 22 of the cylinder 21 is provided with an assist plug 23 projecting toward the lower mold 10. Further, the upper base 9 is provided with a hermetically-sealed envelope 24 having a cutting blade 25 that matches the inner blade 11 of the lower mold 10 around the assist plug 23.

The stacking device III has a partition 31 which is parallel to the traveling direction of the conveyor 34 by forming a slight gap between the shout 31 having a circular cross section and an L-shaped curve having an inlet 32 at its upper end and a horizontally traveling conveyor 34. A plate 35 is arranged, and a step 36 is formed between the outlet 33 of the shout 31 and the conveyor 34 so that the outlet 33 is slightly raised.

Reference numeral 41 denotes an adsorbing device, which is provided with a suction box 42 and has a suction port 43 for sucking outside air on the lower surface of the box which is located above the mouth of the lower mold 10 shown in FIG. 3 and faces the mouth. It is provided so as to move back and forth between the position (i) and the discharge position (ii) above the entrance 32 of the chute 31 shown in FIG. A hose 46 connected to the on-off valve 45 is provided.

The on-off valve 45 switches the inner space of the suction box 42 to the exhaust blower 44 or to the atmosphere, and brings the adsorption port 43 to the atmospheric pressure together with the atmosphere communication.

As is well known, the resin sheet C has both ears fed by a clamp chain, and the product is thermoformed in a row at a right angle to the feeding direction, and the upper mouth is cut at the same time as the molding, and the sheet waste C1 generated by the cutting is formed. At the end of the clamp chain,
It is cut by a cutter device 51 provided at the upper and lower sides, dropped on a sheet waste discharging conveyor (not shown), and discharged in a direction perpendicular to the feeding direction of the waste.

In the apparatus of this embodiment, the resin sheet C is plugged into the plug enclosing tube 24 as shown in FIG.
The ram 8 rises from the position shown in FIG. 1 to a little higher than the position shown in FIG. The resin sheet C is cut in accordance with. On the other hand, knockout rod 12
And the lower base 7 do not move together, so a knockout pin
14 does not move, and the knockout mold 13 remains on the bottom surface of the lower mold 10. (It may rise a little, but it does not rise positively.) At the same time, since the assist plug 23 enters the lower die 10 by the rod 22 of the cylinder 21, the resin sheet C held by the overlapping of the inner blade 11 and the cutting blade 25. Is blown downward, and at the same time, a pressure air is blown out from the assist plug 23 (or the inside of the closed envelope 24) to form a cup-shaped product P in the lower mold 10, and a knockout mold is formed by the bottom ring Pa.
Stable supported on 13. At the same time as this molding is completed, the lower mold
10 goes down with ram 8 to the original position as shown in Fig. 3,
Product P is knockout rod 12 and knockout pin 14
And the knockout mold 13 knocks out on the lower mold 10.

When the product P is molded and knocked out on the lower mold 10 in this manner, the suction port 43 is moved to the discharge position (ii) shown in FIG. 1 at the timing of this knockout.
The suction box 42 of the adsorption device 41, which is moving to the inlet 32 of 31), moves to the take-out position (i), opens the on-off valve 45, sucks the outside air from the suction port 43, and sucks the product P. It sucks up above the knockout die 13 and adsorbs it, immediately returns to the discharge position (ii) and moves, and closes the on-off valve 45 to bring the inside of the suction box 42 to atmospheric pressure. As a result, the product P falls into the inlet 32 of the shout 31 in the stack device III.

The product P that has fallen into the inlet 32 of the short 31 slides on the inner surface of the short 31 and is laid sideways at the outlet 33, and is slid to the mouth of the product P before moving within one molding time by the conveyor 34 to be stacked.

(Operation) Since the operation of the present invention often overlaps with the operation of the embodiment, the description thereof will be omitted.

(Effect) According to the present invention, a take-out position (i) located above the mouth of the mold 10 and facing the mouth, and a molded product P molded by the mold 10.
Is provided above the chute inlet 32 and provided with a suction port 43 that moves back and forth between the discharge position (ii) facing the inlet 32, and the molding is extruded from the mold 10 by the knockout pin 14 at the suction port. Since the product P is transferred to the chute and discharged, it has the effect of making the supply to the stacking device extremely accurate and easy.
