A kind of feeding cutting device of parcel delivery machine
Technical field
The present invention relates to a kind of automation equipment, particularly a kind of pouch that is used for attaches the feeding cutting device of expecting parcel delivery machine.
Background technology
The pouch parcel delivery machine is a kind of automation equipment that is widely used in food, medicine and daily necessities industry; Its radical function is that single bag after the packaging bag that strip links to each other is cut off and will be cut off is thrown on the bag object, like the drying in the material bag in the instant noodles and medicine, the food bag or anticorrosion bag etc.
Currently, charter usually cast pouch length detection, color detection or mechanical means to detect the thickness of the cutting position to the bag through the line positioning, the basic form of the structure shown in Figure 2, including the guide plate detection sensors, pressure wheels and the cutter group, and detects the pressure sensor is disposed above the wheel, since the structure adopted is a fixed length detection, which are adapted Der Sheng deficiencies first differential, it is mainly different in the sub-categories of materials package size differences were due to be adjusted, followed by even resize accurate, and the entire strip package in the manufacturing process is also often appear the phenomenon of varying lengths, so that the process of the Central Standing Committee missed slitting and cutting package material bag and so on.
Summary of the invention
Technical matters to be solved of the present invention is, and is not enough to above-mentioned existence, provide a kind of and all can implement fast, efficiently cut arbitrary size pocket, and the feeding cutting device of the parcel delivery machine that need not to regulate.
Technical scheme of the present invention is: a kind of feeding cutting device of parcel delivery machine; Comprise the passage that guide plate, press nips, cutting knife group, detecting sensor and feed bag are carried; Between detecting sensor and cutting knife group, be provided with master control set by computer operating; Said detecting sensor is arranged between press nips and the cutting knife group, and distance is certain value H between the cutting edge of the probe of detecting sensor and cutting knife group.
Further: moving used time of distance of the material contracted affreightment that above-mentioned definite value H caused and detection signal receive processing and instruction is complementary used opening time to cutting knife.
The present invention is arranged at detecting sensor between press nips and the cutting knife group owing to having adopted; Particularly be set to certain value between the cutting edge with the probe of detecting sensor and cutting knife group; When detecting sensor detects on the strip strip arbitrary sealing; Just with signal feedback to master control set; And send action command to the cutting knife group by it; Pocket movement travel this moment is cut thereby accomplish also just to the H value lower limit that sets accurately and efficiently.
Adopt technique scheme through change to original parcel delivery machine detection position; Make the variation of the detection mode generation essence of parcel delivery machine; Because above-mentioned detecting sensor only detects the signal that seals; And need not to expect the detection of packet length; Created 300 bags/minute more than high efficiency; And when operation, only need a switch, need not consider that material bag size just can realize simple working the most.
Below in conjunction with accompanying drawing the present invention is done further detailed explanation.
Description of drawings
Fig. 1 is an integral structure scheme drawing of the present invention;
Fig. 2 is the prior art structural representation.
The specific embodiment
Like Fig. 1, shown in Figure 2; A kind of feeding cutting device of parcel delivery machine; Comprise the passage 6 that guide plate 1, press nips 2, cutting knife group 3, detecting sensor 4 and feed bag 5 are carried; Between detecting sensor 4 and cutting knife group 3, be provided with master control set by computer operating; Said detecting sensor 4 is arranged between press nips 2 and the cutting knife group 3, and distance is certain value H between the cutting edge of the probe of detecting sensor 4 and cutting knife group 3.
Moving used time of distance of the material contracted affreightment that above-mentioned definite value H caused and detection signal receive processing and instruction is complementary used opening time to cutting knife.Above-mentioned detecting sensor 4 is made up of with sensor receiving transducer 42 sensor emission probe 41, and it is arranged at the both sides of passage 6 respectively.On above-mentioned master control set, being provided with can be with the sharply tuned aligning gear of definite value H.
Whole principle of work of the present invention is to realize like this with action; When the material bag of arbitrary size by passage; When press nips enters into surveyed area; In a single day detecting sensor detects sealing between the pocket; Just can be with the signal feedback that receives to Main Control Tank; And send action command to the cutting knife group by Main Control Tank; Seized material bag then utilizes definite value H between sensor probe to the cutting knife group cutting edge; Realize that signal feedback to cutting knife action This move time and material contracted affreightment move coincideing of used time of distance; More popular; Beaten individual lead exactly; With regard to technique scheme, no matter existing traditional parcel delivery machine is on detection mode, still on structure, all can't realize.
Need to prove once more; Technical scheme of the present invention at first is the change that takes place from detection mode; Become the mode of location, spacing, instantaneous trip by length detection; Its main points are that detecting sensor is arranged between press nips and the cutting knife group; And between sensor probe and cutting knife group cutting edge according to signal collection, feedback, cutting knife action the material bag stroke definite value H that will be provided with the time-join with it; Therefore all by design that any point produced in the technique scheme or the design that under this design concept, is produced, all should be considered as falling into the protection domain of present technique.
