Above-mentioned purpose reaches aspect method like this, promptly be used for grasping and opening empty bag and it is hung and be clamped in method on the pack pipe, wherein, supply and stretching-bag are to realize by known transfer movement, bag is individually grasped and is sent to the pack pipe, then the adhesive spots of the temporary transient effect of grasping mechanism acts on the bag, and the pin of grabbing that pawl is got mechanism is bonded at temporarily that bag is gone up manages so that it is caught, opens and supplies with pack; And when bag is clamped at pack Guan Shanghou, grasping mechanism is thrown off temporary transient the connection with bag, it is characterized by: grab adhesive spots on the pin have less viscosity and be used to grasp and open with gas permeable material system bag.
Above-mentioned purpose reaches aspect equipment like this, promptly be used for grasping and opening empty bag and it is hung and be clamped in equipment on the pack pipe, grasping mechanism comprises the double-type pin of grabbing opposite each other, this is grabbed pin and comprises the temporary transient adhesive spots that plays bonding effect, wherein: adhesive spots is a heat fusion joint, they applied at that time, and they are grabbing adhesive ability on the pin less than the adhesive ability to the material of bag.
The present invention is a departure point with the possibility of known formation bonding connection, in this case, replaces suction pawl etc. with this mechanism.In order to grasp and open the empty bag of especially ventilative and opening, between bag and grippers, set up temporary transient bonding connection.This temporary transient bonding permission makes grippers leave the material of bag without difficulty after open bag is hung and be clamped on the pack pipe, moves and speed by selecting appropriate removing, and does not almost have or can not damage fully the material of bag.
Particularly advantageous is to be the adhesive spots of self refresh in instrument one side, as hotmelt, adhesive strip and gluing roller etc., and also can select velcro (klettbander) for use.
For gluing or adhesion agent can use multiple scheme, wherein both related to gluing itself, the material that also relates to grasping mechanism and adhesion agent or bag is peeled off.
The material of bag except that paper and plastic sheeting, especially Bian Zhi plastics, cotton goods and jute fabric etc.
Advantage by the present invention program mainly is, and is different with the suction pawl, this can be from handling the various ventilative bag materials that wherein also comprise braiding, and grippers itself can design fairly simplely.Especially cancelled pneumatic system.
It is contemplated that from the various known solutions that buttress is piled or the warehouse picks up and fix bag, for example according to DE-A-4116311, EP-A-522110 or WO 95/09765.
