Abstract

PURPOSE:To make a grinder smaller and to prevent various kinds of public pollution by a method wherein a spool runner discharged from a resin molding machine is crushed by a crusher, the crushed matter is carried by air to a grinder through a pipe line, then the ground matter by this grinder is selected and stored. CONSTITUTION:The spool runner discharged from each molding machine 1 is thrown by a dropping means on a robot into the respective crusher 2 and crushed by the crusher 2 into the form of grains. This crushed material is supplied into a common air carrying pipe 3. The crushed material inserted in this air carrying pipe 3 is supplied by a carrying means due to pressure feed or suction into a collecting cyclone 5. The crushed material supplied into the collecting cyclone 5 is ground by a grinder 4, then selected by a selector 6 and supplied into a hopper 7 to grind the spool runner and stored.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for treating spool runners generated during plastic molding. A general plastic molding factory (2) is equipped with a large number of molding machines to enable mass production of plastic molded products, but these plastic molding IEt1-
C: A large amount of spool runner is discharged. Therefore, as a conventional treatment method for spool runners discharged from these molding machines, for example, as shown in Fig. 1C-2,
A side conveyor B for transferring spool runners is arranged for each molding machine, which is installed in large numbers, and a main conveyor B42, which is commonly connected to each side conveyor B4, is also provided at the end of each side conveyor. The spool runners transferred by each side conveyor B are then supplied to a crusher by the main conveyor Dc, and the spool runners crushed by the crusher Dc are sorted by a sorter 1. It was stored in storage container y. Therefore, in the conventional spool runner processing method, the spool runners discharged from each molding machine remain relatively large and do not change their original shape until they are supplied from the side conveyor B to the crusher D (2). In order to transfer the raw materials as they are, it is necessary to install a side conveyor or main conveyor that is wider than the processing capacity, and the input diameter of the crusher must be set large. However, the installation space for the spool runner processing device became large, and there were restrictions in terms of layout.

The present invention has been made to solve such problems, and its gist is that a coarse crusher is installed in each molding machine instead of the side conveyor described in the conventional example; The width of the crushed material discharged from the pipe is pneumatically transported by a pipeline.

The purpose is to reduce the equipment cost and area of conventional conveyors and streamline the processing of spool runners.

The details of the present invention will be described below based on the embodiment shown in FIG.
=Explain. 1 1 is a plastic molding machine (injection molding machine) in which a large number of plastic deck molding machines (injection molding machines) are installed, and each molding machine is equipped with a coarse crusher 2. The coarse crushed material crushed by each crusher 2) is supplied to the collection knife 5 of the crusher 4 through a pneumatic conveying pipe. 7 is a sorter for sorting materials; 7 is a sorter 6 (a hopper for storing the resin that has been sorted out from the second one); 8 is a suction blower for sucking the crushed materials in the pneumatic transport vibro and guiding them into the collection cyclone 5; However, the air transport means based on such a suction blower C may be an air transport means based on a pressure feed blower.

The above is the structure of the spool runner processing device according to the present invention. 2, the crushed material is fed into a crusher 2 and crushed into particles by the crusher 2.This crushed material is supplied into a common air transport pipe δ, but inside this air transport pipe 3 (= The crushed material is fed into the collection cyclone 5 by means of transportation C2 by pressure or suction 4.The crushed material introduced into the collection cyclone 5 is crushed by the crusher 4I and then sorted. 1a6
The spool runners are sorted out from the two and supplied into the hopper 7, where the spool runners are pulverized, and the spool runners taken out from each molding machine 1 are pulverized and stored.

As described above, the method for treating spool runners according to the present invention is as follows: The pneumatic conveying pipe (=transportation means C2) is supplied to the crusher (=supplied and crushed.

Since the present invention is designed to be processed, the following effects can be obtained.

The spool runner is supplied to the crusher 4 after being coarsely crushed. can also be made smaller.

濤 The miniaturization of the crusher mentioned above has the effect of making it easier to incorporate a sorter and metal separator into a system.

(c) Since the means of transporting the spool runner is a pipeline, space can be used more effectively compared to the conventional means of transport using a conveyor, so the installation space can be reduced. The cost is low.Also, since the transportation route is a closed V-stem, there is no contamination of foreign matter in the transportation route, and pollution such as noise, air pollution, and bad odor can be eliminated.

(D) Since the spool runner is coarsely crushed in the first stage and crushed in the second stage, the crushed particle size is constant and the number of miscut products can be reduced.

- Since the crushed spool runners are transported by pneumatic force, problems such as the spool runners getting caught or getting caught on the back side of the belt, which tend to occur when using conventional conveyors, do not occur.
