Abstract

PURPOSE:To prevent blocking phenomena from developing by a constitution wherein a group of products are run in a row from the outlet of a chute in the order of the displacement actions of valve members by displacing the valve members in holding position one row at a time to release the position. CONSTITUTION:When products P and P are released simultaneously, a valve member 48 in an inlet pipe 42a is in holding position and consequently the product P, which is released and falls in an inlet pipe 42 equipped with no valve member 48 slides through a guide part 43 to an outlet 44. After that, the valve member 48 is controlled so as to displace to release position in order to slide the product P in the inlet pipe 42a to the outlet 44 of the guide part 43, resulting in entering the product in the mouth of the previously slidden product P so as to be stacked together. When three rows or more of molds are arranged in the feeding direction of resin sheet C and three or more of inlet pipes 42, 42a... are provided, the displacements of the valve members 48... to release position are controlled in order one inlet pipe after another. Thus, products in three rows or more can be fed in order to the single outlet 44 of the guide part 43, resulting in developing no trouble, which makes the discharge of product from the outlet 44 impossible.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention is directed to an apparatus for molding a product by simultaneously performing thermoforming of the product and trimming around the mouth of the product using a 04 resin sheet as a molding material. Trimming position (i) is achieved using a suction device that has multiple rows of molds in the feed direction and suction ports arranged at the same number of rows and pitch as the rows of molds.
The product is adsorbed and transferred to the discharge position (ii), and is discharged all at once toward the multiple rows of inlet pipes of the shooter below.
The structure is such that the liquid is discharged from the exit of the shooter in a single line without any confusion.

(Conventional technology) There is no device similar to the present invention.

(Problem to be solved by the invention/purpose of the invention)! fJ
It is well known that a mold for an I-oil sheet forming apparatus is provided with a cutting blade for trimming the mouth portion at the same time as forming. However, when we attempted to design a molding device suitable for the mass production of resin molded products such as pots using this method, we found that in this molding device, the molds that perform the trimming action are arranged in multiple rows in the feeding direction of the resin sheet. If trimming is not performed, production efficiency will be poor. However, there is a shooter which simultaneously sucks the trimmed products formed by the plurality of rows of molds and transports them toward the discharge position, and whose upper opening is relatively narrow so that each of the trimmed products can be accommodated without having to lie down.
However, if all adsorption trimming products are discharged at the same time and multiple rows of products are received by multiple rows of shooters, it is difficult to dispose of the products in the lower row that were previously discharged. If products are always stacked in the same chute, no matter how many products are shaped to prevent overlapping, products with the same shape will overlap and cause a blocking phenomenon that makes it difficult to remove.

The present invention aims to solve the problem of preventing such a blocking phenomenon from occurring during discharge in a configuration in which trimmed products in multiple rows are simultaneously taken out in the feeding direction of a resin sheet. This is the object of the invention.

(Means for Solving the Problems) The present invention has been made to meet the above-mentioned objectives, and includes a plurality of molds equipped with cutting blades for trimming around the mouth of the product in a plurality of rows in the feeding direction of the resin sheet. Trimming position (i)
and a discharge position fi(ii), which is provided with a shooter below, in which multiple rows of inlet pipes are provided in accordance with the pitch of the multiple rows of the mold, and each of the inlet pipes is assembled into a single row of guide parts; It consists of a suction device equipped with suction ports that match the pitch of multiple rows, and a valve member that can be displaced to two positions, a product support position and a product discharge position, is installed on each inlet pipe of the chute, except for one inlet pipe or all of the inlet pipes. The adsorption device is moved to the trimming position (i) to adsorb products in one group in multiple rows at once, and the adsorption device is moved to the discharge position (ii) to remove the products all at once. The discharge operation is controlled, and when the products are discharged all at once into each inlet pipe of the chute, the valve member is placed in the support position, and thereafter the valve members are sequentially shifted to the discharge position one row at a time to release the products into each inlet pipe of the shooter. This relates to a trimming product take-out mechanism for a molding device, characterized in that the product is configured to flow out from the outlet of the shooter in a line in the order of the displacement operation of the valve member, the product being taken out and discharged into the shooter. can be applied in an orderly manner.
