Abstract

PURPOSE:To keep the opening part of a bag in a non-openable condition at the time of conveyance and deliver a bag type object to a receiving member in a suitable condition by providing a conveying member for grasping the end part of the bag type object which is taken out by means of a take-out member from both sides by means of a grasping member, and for rotating the bag type object. CONSTITUTION:Bag type objects 11 which are stackedly housed in an accumulating member 20 are taken out one at a time by means of a take-out member 30. Then, the end part 11A of the bag type object 11 which is taken out is grasped from both sides thereof by means of the grasping claw members 45A, 45B of a conveying member 40 and, in the closed condition of the opening part of the bag type object 11, the bag type object 11 is rotated and delivered to a receiving member 50.

Description

Detailed Description of the Invention (1) Object of the Invention [Industrial Field of Application] The present invention relates to a bag-like object removal device, and particularly to a bag-like object taken out from a PJ material by a take-out member. The present invention relates to a bag-like object retrieval device that rotates by gripping the tip end of the bag from both sides with gripping claw members.

[Prior Art] Conventionally, this type of bag-like object retrieval device has a system in which the bag-like object accumulated on a depositing member is sucked and taken out from one side by a suction member of a take-out member, and then the bag-like object is removed from one side by a suction member of a conveyance member. A system has been proposed in which the bag-like material is sucked from a pick-up member and rotated to be conveyed and supplied to a subsequent receiving member.

[Problems to be Solved] However, in the conventional bag-like object retrieval device, the suction member of the conveyance member had to pick up the bag-like object only from one side, so it is difficult to attract the bag-like object in particular near the IJJlr part. If you need that opening to receive it! There is a drawback that the bag is opened before being delivered to the receiving member, making it impossible to deliver the bag to the receiving member in a suitable state (that is, in an unopened state).

Therefore, in order to solve this problem, the present invention grasps the leading end of the bag-like object taken out from the stacking member by the take-out member from both sides by the gripping claw members of the conveyance member, rotates it, and delivers it to the receiving member. The present invention aims to provide a bag-like object retrieval device.

(2) Structure of the invention [Means for solving the problem] The means for solving the problem provided by the unissued IJJ is “(
a) a stacking member for storing bag-like objects in a stack; and (b) a take-out member for taking out bag-like objects one by one from the stacking member.

(c) a conveyance member that rotates while gripping the tip end of the bag-like object taken out by the taking-out member from both sides with a gripping claw member.

[Function] Bag-like object removal according to the present invention! The position is the tip of the bag-like object that the extraction member has taken out from the accumulation member! The part a is gripped from both sides by the gripping claw members of the conveyance member and rotated.
This also serves to prevent the opening of the bag from being opened when being transported by the transporting member.
