In addition, the process that in the utility model one embodiment, label is adsorbed on labeling treating device is: labeling treating device fortuneMove to the top of the first suction mark support, bottom and the label of labeling treating device first adsorb, then along with labeling treating deviceMove down, label can slowly contact hairbrush, along with downward impact, surrounding air to label have a kind of toOn thrust, under hairbrush auxiliary, label can wrap tool gradually, along with labeling treating device moves down,The area of parcel increases gradually, last to wrapping up completely. Be positioned at above labeling treating device with traditional approach labelLabeling mode is compared, and the attaching of label relies on the gravity of self and the vacuum of brush marking machine structure to realize vacuum suction,This mode needs larger vacuum capacity, and energy consumption is larger, and cost is higher, and traditional approach labeling requirement is being pastedMark tool moves to label labeling treating device top after moving to precalculated position again, and this programme can be by labelAfter first placing, labeling treating device moves from the top down and can complete label attaching action, and the time is shorter, has shortenedProduction cycle.

Refer to Fig. 1, the bearing of trend of stacker mechanism 270 is parallel with the die sinking direction of injection machine 10, that is,In stacker mechanism 270, the stacking direction of injecting products is parallel with the Product Status injecting in injection machine, like this,Get product tool by after the injecting products taking-up in injection machine, can be by injecting products by the translation of mechanical armDirectly be positioned in stacker mechanism, compared with traditional structure, saved the upset of the corner of mechanical arm, reduceThe logical action of manipulator motion, shortened cycle of operation of mechanical arm, improved production efficiency, simultaneouslyAlso reduced the manufacture difficulty of tool.

Refer to Figure 11 and Figure 12, stacker mechanism 270 comprises the first fixed head 271, the second fixed head 272And the some connecting rods that be arranged in parallel 273, the first that connect the first fixed head 271 and the second fixed head 272 are solidDetermining plate 271 offers entrance 274, the second fixed heads 272 that enter for injecting products and offers for injecting productsThe outlet 275 of leaving, the two ends of connecting rod 273 lay respectively at entrance 274 and outlet 275 edges, connecting rod273 bearing of trend is identical with the die sinking direction of injection machine 10, and connecting rod 273 is for guiding injecting productsStacking direction. Compared with traditional conveyer belt, above-mentioned stacker mechanism, can realize injection moulding without power-equipmentProduct automatically stacking, structure is simpler, and the space taking is less, and cost is lower.

Further, refer to Figure 11, connecting rod 273 is provided with positioning sleeve 276 near one end of entrance 274,Positioning sleeve 276 is sheathed on connecting rod 273. Concrete, positioning sleeve 276 is fixedly installed on connecting rod by jackscrew273. Further, the length of positioning sleeve 276 is less than connecting rod 273. Preferably, the length of positioning sleeve 276Degree is roughly equal with the length of injecting products on stacking direction. Be fixed on heap by positioning sleeve through injecting productsIn folded mechanism.

Further, the size of entrance is mated with the external diameter of injecting products, that is, and and according to the shape of injecting productsAnd the size of big or small inlet porting, injecting products can just be penetrated from entrance. Further, positioning sleeve 276On be arranged with sealing ring 277, and two position phases of sealing ring 277 that are on the positioning sleeve 276 that diagonal angle arrangesWith. , two positioning sleeves 276 that are the connecting rod 273 that diagonal angle arranges in the edge of each entrance 274Same position is provided with sealing ring 277, can realize product introduction connect by the sealing ring of diagonal position between twoProduct tool, is got and the initiating terminal of injecting products can be fed through the position of sealing ring in the position location of bar that isPlace.

Further, in order to realize the location of injecting products in stacker mechanism, refer to Figure 11, first is solidDetermine the edge that plate 271 is positioned at entrance 274 and be provided with heap laminate 278, it is first solid that heap laminate 278 is arranged atDetermine plate 271 one end near the second fixed head 272. Injecting products is entering stacker mechanism by entrance 274In, pile laminate 278 when advancing to injecting products and getting product tool and depart from completely by jack-up, heap laminatesSheet 278, by self elastic force resilience, withstands the initiating terminal of injecting products, and the initiating terminal of injecting products also simultaneouslyJust in time be positioned at the positioning area of sealing ring, by the positioning action of heap laminate and sealing ring, to ensure injection moulding productThe uniformity of the each position of placing of product.

Refer to Figure 12, the first fixed head 271 is provided with brush 279 away from the surface of the second fixed head 272,Brush 279 is installed on the bottom of entrance 274, and the bristle of brush 279 covers entrance 274 at least partly. CanTo understand, injecting products enters after stacker mechanism, because sealing ring can be realized determining of injecting products initiating terminalPosition, and the end of injecting products may be in vacant state, due to the effect of self gravitation, end can be saggingAnd affect entering of next product, by be provided with brush in the bottom of entrance, can enter at injecting productsEnter the end of rear picking-up injecting products, avoid the sagging of injecting products end, so that next injecting productsEnter.

Further, the first fixed head 271 is positioned at entrance 274 both sides near the surface of the second fixed head 272Position be also provided with brush 279. By the brush of entrance both sides, can prevent that injecting products is on connecting rodOccur rocking and affect entering of next injecting products, improving the stacking effect of injecting products.

In the present embodiment, the edge of each entrance 274 is provided with 273, four connecting rods of four connecting rods273 are uniformly distributed along the distribution of entrance, further improve the stacking effect of injecting products in stacker mechanism.

Further, in order to improve the production efficiency of in-mold label system, concrete, brush marking machine structure 250 wrapsDraw together two first suctions and mark supports 252 and the second suction mark support 253, and support 252 is marked in the first suction and the second suction is markedThe corresponding setting of support 253 homogeneous one. Accordingly, label transport establishment comprises that four are inhaled mark assembly 234, that is,On each suction mark fixed bar 2321, be provided with two and inhale mark assemblies 234. Accordingly, label placement mechanism 210Comprise four label rest areas, that is, it is two that label is placed plate 211, and two labels are placed plate 211 along verticalArrange to stack, each label is placed on plate 211 and is provided with two label guide rods 215. Accordingly, machineryOn arm 301, be respectively arranged with four labeling treating devices 302 and four and get product tool 303. In like manner, stacker mechanismThe first fixed head 271 of 310 offers four entrances 274, like this, can realize a die sinking and produce simultaneouslyGo out four injecting products, greatly improved the production efficiency of in-mold label system.

Each technical characterictic of the above embodiment can combine arbitrarily, for making to describe succinctly, not rightThe all possible combination of each technical characterictic in above-described embodiment is all described, but, as long as these skillsThere is not contradiction in the combination of art feature, is all considered to be the scope that this description is recorded.

The above embodiment has only expressed several embodiment of the present utility model, its describe comparatively concrete andIn detail, but can not therefore be interpreted as the restriction to utility model patent scope. It is right to it should be pointed out thatIn those of ordinary skill in the art, without departing from the concept of the premise utility, can also doGo out some distortion and improvement, these all belong to protection domain of the present utility model.
