A bag filling system and filling method

Abstract

The invention discloses a bag body filling system. The bag body filling system comprises a control component and a detection component used for detecting whether bag bodies are normal or not. The detection component comprises a first detection piece used for detecting a fixture, a second detection piece used for detecting connectors, corresponding to the fixture, of each bag body and a third detection piece used for detecting a film, corresponding to the fixture, of each bag body, and the first detection piece, the second detection piece and the third detection piece are all installed between a bag-making station and a filling station and connected with the control component. The invention further discloses a filling method. In the process of transmitting the bag bodies between the bag-making station and the filling station, within the time that the first detection piece continuously detects the fixture, the second detection piece and the third detection piece conduct counting on the joints and the bag films respectively and transmit the counting results to the control component, and the control component judges whether the clamped bag bodies are abnormal or not according to the number of the joints and the number of the bag films. The bag body filling system and the method have the beneficial effect of being capable of precisely judging whether the bag bodies are abnormal or not in an online manner.

Description

technical field [0001] The invention mainly relates to the control field of food, medicine and other packaging equipment, in particular to a bag filling system and a filling method thereof. Background technique [0002] At present, the soft bag production line is to transfer the bag made by the bag making station to the filling station for filling. Before filling, the soft bag needs to be inspected. The current soft bag inspection adopts two methods: 1. , Use multiple photoelectric switches to detect the interface of each soft bag in each group of soft bags, that is, the number of photoelectric switches is equal to the number of interfaces of each group of soft bags in the soft bag line; if there are two soft bags in each group and each soft bag If the bag has a single interface, two photoelectric switches are required; if each group consists of two soft bags and each soft bag has two interfaces, four photoelectric switches are required; 2. Multiple photoelectric switches ar...

Problems solved by technology

Therefore the above two methods all have the following disadvantages: 1. The first detection method needs more photoelectric switches, and when there is an interface but no bag film, the detection method will think that the bag is a good bag, and the bag will appear. Misjudgment; 2. The second detection method also requires a relatively large number of photoelectric switches. When there is no interface on the film or there is a lack of interface when making a multi-interface bag, this method is still considered to be a good bag; and because the film There will be some deformation after being heated. In a static state, the photoelectric switch may not be detected due to the deformation of the film, and the bag film may not be detected.

Therefore, if the above two methods cannot detect unqualified soft bags, it will lead to misfilling, causing the filling liquid to flow into the equipment of the production line, causing waste of liquid medicine and polluting the production environment
