Certainly, should be understood that here accompanying drawing and explanation casehistory just, can make various changes and modification and do not deviate from the spirit and scope of the present invention.
Same numeral in each accompanying drawing is represented identical parts.
When relating to most preferred embodiment, for the sake of clarity adopt some term.Use such term not only to attempt to comprise described embodiment, and comprise with the same manner operation and work and bring the technical equivalents thing of identical result.
Now especially with reference to accompanying drawing 1 to 14B, this device comprises casing 10, the front 12 of this casing 10 has a slot 11, its objective is to make plastic bag pass wherein motion by hope.Casing 10 has a top cover 14, top cover 14 be hinged on casing left side and by kayser at 15 places, casing 10 right sides.
One plastic bag roller 16 is arranged on the mandrel 17, and mandrel 17 is supported by two mountings 18 that are installed on the casing 10.For pair of rollers 16 loads, make mandrel 17 pass roller 16, be arranged on it on mounting 18 and push in its groove.Roller 16 comprises the continuous band-shaped plastic bag on the spool, and this plastic bag has potted line 19 and perforation line 20, and this perforation line 20 forms the profile of the single sack 21 that will separate, and also has bar code label 21A on this plastic bag.Casing 10 has backing roll 22,23 and 24, and these backing rolls are supported by the cylindrical bearing of installing in present 26 and 27 25.The plastic pipe that is driven plain has a top layer 16A and a bottom 16B to form plastic bag 21.
The banded plastic bag 21 that is in non-separation state is upwards walked around above the roller 22, stride across foam rubber sheet pad 28 again, arrive below the bottom roller 23, upwards walk around above the top roller 24, arrive slot 11 outsides then, thereby the bottom of bag 21 is suspended on downwards near on the outer front 12 of casing 10 bottoms.
One photoelectric switch 30 is installed on the frame 10 by carriage 31, this switch is the bar code recognizer that can discern the bar code label 21A on the bag 21, used bar code label 21A so that potted line 19 location are formed the bag end 21 in the past in bag is made, this switch is also discerned the perforation line 20 to the location, top of bag 21.Bar code label 21A and switch 30 1 the work stop position and the length of the bag 21 determining to be transported.
This device have be positioned at casing 10 open bag mechanism in advance, comprise that one is installed in the foamed rubber backing plate 28 on the platform 32, this platform 32 extends and is fixed on (two) sidepiece of casing 10 across ground.Roller 22 is supporting sack 21 so that they by backing plate 28, preferably make it above backing plate and apart from its 1/8 inch.
Be provided with one and be positioned at bag top and by the clip mechanism or the clamping frame 35 of guide bolt 59 carryings and have pull back spring, its bolt is engaged with in the carriage 51.Clamping frame 35 is used for clamping or bite sack 21 with foamed rubber backing plate 28, and is striding the sack 21 of perforation line 20 to be fixed for opening in advance.
Clamping frame 35 is one to have three channel members that are fixed on in-to-in wear strips 36, and every end has one, and the centre has one.Wear strips 36 has hole 37 to hold shoulder bolt 38, and bolt 38 is with finger 39 engagements and be articulated in this.Finger 39 can be made by aluminium or plastics, and the mode that foamed rubber backing plate 40 can any hope is connected with its (39), as the bonding mode by known type.
Two screw actuators 50 are set, be connected with switch 30, this screw actuator 50 is installed on the adapter plate 52 that is fixed in casing 10 by carriage 51, and engages to move down clamping frame 35 with clamping frame 35 plastic bag 21 is clipped on the backing plate 28, limits it and be transported when open on the top of bag.One air compressor motor 55 is set, and this air compressor motor 55 also is connected with switch 30, and is installed in by screw 56 and carriage 57 on the surface 12 of casing 10.
Mode of operation is described now.Owing in casing 10, have the roller 16 of plastic bag 21, and can obtain one bag of part 21 at slot 11 places, client pulls out a sack 21 ' downwards in casing 10 outsides, bar code reader 30 detects the bar code label 21A of next sack 21 in the casing subsequently, thereby start screw actuator 50, clamping frame 35 is moved down, next sack 21 is clipped on the backing plate 28, make sack 21 stop to move, but also start air compressor motor 55, an air is blown in the exterior bag 21 ' of casing to open the sack 21 ' that this will use.
Because clamping frame 35 engages with next sack 21, the wind that is blown into is opened bag 21 ', and client can insert his or her finger (not shown) wherein and take off the bag 21 ' that will use.
Because next sack 21 is clipped on the backing plate 28 securely, then drive this linear actuators 45, it moves drive plate 43, promote the shoulder screw 41 in the groove 42, finger 39 is rotated down, make 40 on backing plate clamp bag 21 top layer 16A and it is moved in the opposite of bottom 16B mode, because the smooth character that plastic sheeting has makes bottom formation minimum drag.
The mobile of top layer 16A on bottom 16B opposite ruptured the perforation line 19 among the top layer 16A, and the perforation line among the bottom 16B is kept perfectly.When actuator 45 stretched out fully, screw actuator 50 stopped, and by the pull back spring 58 that is engaged on the guider screw 59 in the carriage 51 clamping frame 35 was moved up.
When clamping frame 35 moves on this position, it will start linear actuators 45, and drive plate 43 is moved, and correspondingly rotate finger 39 and turn back to its initial position.
Can repeat this operation on request, its operation order is outwards and to surface, lower edge 12 to extract sack 21 ' beginning out by the user, identifies this bar code label 21A up to bar code recognizer 30 and ends, and then described operation begins (repetition).
With reference to Figure 15, shown the device 100 of automatic distribution sack 21 in addition.
On above-mentioned device, added the roller 101 and 102 of feeding pocket 21.Being provided with one can be by the drive motor 103 of known switches (not shown) startup, and this switch can and be installed in casing 10 outsides by client's shake-up.
Motor 103 has a driven wheel 104 and a chain 105, it is meshed with driven wheel 104 and driven wheel 106, driven wheel 106 is connected in and drives this roller 101, driven roller 101 rotations are also sent sack 21 to, bar code recognizer 30 up to it detects its bar code label and motor 103 is stopped, and as mentioned above, when client's starting switch (not shown), with the order that begins by client sack 21 is opened in advance, distributes and all opened, so that sack of primary distribution.
This shows, the device that can realize the object of the invention is provided.
