Abstract

PURPOSE:To automatically pile-up molded articles by transferring the molded articles sent-out onto an upper-stage discharge passage at the edge of a resin molding machine, onto the lower-stage transport passage under a shutter apparatus through the opening and closing movement of the shutter apparatus. CONSTITUTION:The sheet (a) which is molded to a molded article (b) by a molding apparatus 4 is transported onto an upper-stage discharge passage 5 by a clamp chain 2. Since a shutter apparatus 16 is at the closed position shown by the full line at this time, the sheet (a) is sent into the shutter apparatus 16 and stopped. Then, a cutter 15 is operated, and the sheet (a) is cut to a prescribed length. At the same time, a cylinder 29 is operated, and a holding member 35 lowers through a lever 26 onto the shutter apparatus 16, and the sheet (a) is absorbed by the negative pressure generated in the holding member 35 by the revolution of a suction fan 42. Then, the shutter apparatus 16 is released by a cylinder 19, and the sheet (a) is lowered in this state and loaded in piled state onto a lower-stage transport passage 12.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a molded product stacking and processing device whose main purpose is to stack and process molded products that are molded by a resin molding machine and are intermittently discharged. an upper discharge path through which the molded products are intermittently sent out; a lower conveyance path; and a shutter device that can be freely controlled to open and close, forming an extension of the upper discharge path on the base point of the upper discharge path; It is installed above the shutter device and descends onto the closed shack device to grasp the molded product, and when the shack device is opened, it descends to the lower conveyance path and transports the molded product. The present invention is characterized in that a gripping device including a gripping member that is dropped onto the road is installed.

A preferred embodiment of the invention will be described with reference to the accompanying drawings.

In FIG. 1, (I) is a resin molding machine, and (I[) is a stacking processing device.

The resin molding machine (I) of this embodiment grips the edge edges on both sides of a long resin sheet a wound around a winding shaft 3 by a pair of known uranium butenes 2 provided on a frame 1. The molding device 4ζ is fed through a sheet heating device (not shown) by intermittent driving, and while the uranium butene 2 is stopped, the sheets a and l are formed, and the molded product is placed in the discharge path 5 at the end of the chino 2. It becomes a publicly known configuration without sending out.

The molded product of this embodiment is a resin sheet (a) that is fed into the molding device 4f intermittently. Square containers, round cups, etc. are placed in several rows in the feeding direction and in the middle direction of the sheet (a) within a predetermined area of the sheet (a). It is something that forms.

The stacking device (■) is connected to the turning point of the crumb chain 2 in the discharge path 5, that is, the end of the discharge path 5, as shown in FIG.
Each transport g 12 consisting of a conveyor belt is provided inside the container 1 at a position lower than the discharge path 5. In the present invention, the discharge path and the conveyance path are referred to as an upper discharge path 5 and a lower conveyance path 12 due to the difference in height.

Since the upper discharge passage 5 does not extend into the machine frame of the stacking processing device (I[), a shutter device 16 forming an extension of the passage 5 is provided inside the machine frame 11, and a shutter device 16 is provided at the entrance of the shutter device. Cutting device 1 consisting of receiving blade 13 and movable blade 14
5 will be provided.

As shown in Fig. 2.3, the shutter device 16 is placed at a position where it does not interfere with the lowering of the molded product.
Slider 18.1 fitted in guide rod 17.17 provided in force direction
It is composed of a pair of plates that are fixed at 8 and can be approached from two directions in the middle direction as shown by the solid line in Figure 3, or retreated as shown by the chain line, and the reciprocating movement of opening and closing is controlled by the pair of plates. Controlled by cylinder 19.19.

The lower conveyance path 12 is constituted by a conveyor belt, or is stopped during the operation of the stacking process. The shack device 16 is located directly above the starting work 1 of the lower conveyance path 12.

As shown in FIG. 2, the machine frame 11 has a shaft 22 at the upper end of the first link 21, the lower end of which is fitted into the front and rear shafts 20 of the upper member.
A non-horizontal gripping device frame 24 is attached to the lower end of the L-shaped piece 23 hanging from the L-shaped piece 23, and a shaft 27 at one end of an L-shaped bar 26 with a bent part fitted to a shaft 25 hanging from the front and rear of the device frame ,
An inverted gripping member 35 located on the shutter device 16
, the other end of the I-shaped lever 26 extends above the gripping device frame 24, and the shaft 28 at the other end is provided on the device frame 24 so as to be swingable about a shaft 31. 29 is connected to the loft 30.

A second link 32 protruding diagonally upward is fixed to one first link 21, and the second link 32 is axially connected to a rod 34 of a cylinder 33.

) The national arrival part 35 has a suction port 36 in the center, and the machine frame 1
Suction tower 3 supported by a support 37 erected on the upper member of 1
Both upper and lower ends of the bellows 40 are attached to the suction port 39 of No. 8 and the suction port 36. The suction tower 38 is provided with a suction fan 42 driven by a motor 41 and a plurality of suction force adjustment valves 43.

The cylinder 33 is swingably supported by a shaft 44 on one of the pillars 37 .

To explain the operation of this embodiment, a resin sheet a formed into a molded product by the molding device 4 will be described.
is sent to the upper stage discharge passage 5 by the crumb chain 2, and when performing this feeding operation, the shutter device 16
3 closes as shown by the solid line in FIG. 3, the continuous resin sheet a is sent out from the upper discharge path 5 onto the shutter device 16 and stopped. At the same time as the stoppage, the cutting device 15
The movable blade 14 descends to cut the resin sheet a, and at the same time, the cylinder 29 and motor 4'1 are driven, and the cylinder 29 is contracted to form an L shape and the gripping member 35 is cut through the bar 26. As shown in FIG. 4, the shutter device 16 is lowered, and the negative pressure generated in the member 35 by the rotation of the suction fan 42 adsorbs the molded product and the resin sheet a as shown in the figure, and at the same time the shack device 16 is opened by cylinders 19 and 19 as shown by chain lines in FIG. 3 to open the upper part of the lower conveyance path 12.

Almost simultaneously, the cylinder 33 is driven to contract,
As shown in FIG. 6, the gripping device frame 24 is lowered via the second link 32 and the first link 21. Therefore, the device frame 24 moves downward with a swing movement to the right in FIG. 2 together with the gripping member 35, causing the resin sheet a and the molded product to swing slightly downward to the right. At the same time as the posture shown in FIG. 6 is achieved, the suction force adjustment valve 43 is closed, and the resin sheets a and the like gripped by the gripping member 35 are automatically dropped into the lower conveyance path 12 by their own weight and stacked. If necessary, pressurized air is fed into the suction cylinder 38 below the suction force adjustment valve 43. Since the lower conveyance path 12 is constituted by a conveyor belt, when the number of fallen resin sheets a reaches a certain number, they are conveyed to the right in FIG.

The above-described cycle operation of this embodiment is synchronized with the molding operation of the molding device 4 and the intermittent drive and stop of the uranium butene 2, and after the resin sheet a is dropped onto the lower transport 1a12, The cylinder 33 and the cylinder 29 extend and return as shown in FIG. 2, and the cylinder 19.
19, the shutter device 16 is closed as shown by the solid line in FIG.

The present invention utilizes the configuration shown in the above example to sequentially transport the molded products delivered to the upper discharge passage 5 at the end of the resin molding machine to the lower part of the shank device 16 by opening and closing the shank device 16. This has the effect of automatically transferring the molded products to the lower conveyance path 12 and stacking them without any disturbance.
