Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluid conveyer device for conveying a plurality of types of resin molded products molded by a plurality of resin molding machines based on a set order and carrying them into a predetermined article storage container. It is about.

[0002]

2. Description of the Related Art Conventionally, there has been known a fluid conveyer device which conveys a resin molded product molded by a resin molding machine and carries it into a predetermined storage container. As shown in FIG. 7, a conveyor device of this type is generally arranged mainly corresponding to the resin molding machine 100 upstream of the conveyor, and receives and carries out the resin molded product molded by the resin molding machine 100. Receiving / carrying-out means 101, tubular transfer passage 102 connected to the outlet of the resin molded product receiving / carrying-out means 101, separator 103 airtightly connected to the outlet of the tubular transfer passage 102, and the separator 1
Suction means 104 connected to one outlet of 03 to suck the resin molded product together with air into the separator 103.
And a storage container 105 arranged corresponding to the other outlet of the separator 103 and for storing the resin molded product separated and discharged from the air flow sucked by the suction means 104 in the separator 103. ing. Therefore, the resin-molded product molded by the resin-molding machine 100 is received by the resin-molded product receiving and carrying-out means 101, and then carried out to the cylindrical transfer passage 102. Cylindrical transport passage 1
Since air is sucked into 02 by the suction action of the suction means 104, the resin molded product moves in the cylindrical transfer passage 102 along with the sucked air flow and is introduced into the separator 103. In the separator 103, the suction means 104
The air flow sucked by is separated from the resin molded product. The resin molded product separated from the air flow is discharged from the other outlet and stored in the storage container 105.

However, in the conventional conveyor device described above, a plurality of transfer paths for transferring the same or different resin molded products molded by a plurality of resin molding machines are independently arranged in parallel from the upstream end to the downstream end. Because of the configuration, it is necessary to interpose separators 103 on each of the plurality of transport paths and attach a suction means 104 to each of these separators 103. As a result, the number of parts increases, the structure becomes complicated, the apparatus becomes large, and the like, which requires a large installation space, and the installation space may be restricted and installation may be impossible. Also, the complexity of the structure,
Increasing the size of the device has a drawback in that it causes a price increase and brings an economical disadvantage.

[0004]

The problem to be solved is to convey the same kind or different kinds of resin moldings (hereinafter referred to as articles) molded by a plurality of resin molding machines (hereinafter referred to as article supply means). Since the plurality of transport paths are independently arranged in parallel from the upstream end to the downstream end, it is necessary to interpose a separator provided with suction means on each of the plurality of transport paths, and as a result, the number of parts is increased. Increase in size will complicate the structure and increase the size of the device, which requires a large installation space.Therefore, there are restrictions on the installation space, and the complexity of the structure and the increase in size of the device lead to higher prices. There are various points such as contributing to this.

May supply the same type of articles or different types of articles. In addition, when the plurality of article receiving / delivering means 5, 6, 7, and 8 complete the automatic or manual pre-processing of article unloading such as confirmation of the quantity of received articles and elimination of defective articles by inspection, the control means 28 From conveyor 5A, 5B, 5
The article carry-out signals Op1, Op2, Op3,
Although the operation of outputting Op4 to carry out the article has been described, the article carry-out signals Op1, Op2, Op3, etc. are taken into consideration in consideration of the conditions in the manufacturing process management of the article or other conditions.
The output order of Op4 can be arbitrarily selected and changed. Furthermore, four article supply means 1, 2, 3, 4 and four primary side cylindrical transfer passages 9, 10, 11, 12 and four secondary side cylindrical transfer passages 15A, 15B, 15C, 15D are used. However, in the present invention, the article supply means 1, 2, 3, 4 and the primary side cylindrical transfer passages 9, 10, 11,
12 and the secondary side cylindrical transfer passages 15A, 15B, 15
The numbers of C and 15D are not limited to those in the above embodiment, and it is possible to adopt any integer of 2 or more. Furthermore, the transport passage collecting means 13 is constituted by beam members arranged horizontally and in a straight line in the width direction of the conveyor,
A mounting portion 13B extending downward is attached to the back surface of the beam member, and the outlets of the primary-side cylindrical transport passages 9, 10, 11, 12 are opened and collectively arranged in the mounting portion 13B in a horizontal parallel state. However, the direction and shape of the beam members that constitute the transfer passage collecting means 13, the direction and shape of the mounting portion 13B, and the secondary side cylindrical transfer passages 15A, 15 with respect to the mounting portion 13B.
The parallel arrangement pattern of the outlets of B, 15C, and 15D is not limited to the horizontal and straight line shape in the width direction described in the above embodiment, but may be a horizontal arc shape, a zigzag shape, or a vertical straight line. Different parallel arrangement patterns, such as a circular shape, an arc shape, and a staggered shape, can be appropriately selected and arbitrarily adopted.
Of course, it goes without saying that the articles are not limited to resin molded articles.

[0016]

As described above, according to the present invention, the articles supplied from the plurality of article supplying means are received by the plurality of article receiving and carrying out means, and one article receiving and carrying out means selected on the basis of the order from the control means. An article unloading signal is output to carry out the article unloading, and at the same time, the secondary side cylindrical transport passage corresponding to the primary side tubular transport path that is connected to the article receiving and unloading means where the article unloading is performed is connected. The passage selecting signal is output from the control means to the outlet so that the passage selecting means is made airtight, and the article carried out to the primary-side cylindrical transfer passage is sucked together with air by the suction action of the suction means to separate the separator. The article that has been introduced into the separator and separated from the air flow in the separator can be discharged from the other outlet and received by the article receiving means. In other words, by operating one suction means, one transport path can be sequentially selected from a plurality of transport paths that are independently arranged in parallel, and the article can be transported, so that the number of suction means used is one. Can be reduced to Therefore, reduction of the number of parts,
