Accompanying drawing is used to provide further understanding of the present utility model, constitutes the application's a part, and illustrative examples of the present utility model and explanation thereof are used to explain the utility model, do not constitute improper qualification of the present utility model.In the accompanying drawings:
Fig. 1 is that the bottle blowing machine of prior art turns over base mechanism and partly cuts open structural representation;
Fig. 2 be the utility model preferred embodiment partly cut open structural representation; And
Fig. 3 is the ring cam set spare plan structure schematic diagram of the utility model preferred embodiment.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
Fig. 2 be the utility model preferred embodiment partly cut open structural representation, as shown in Figure 2, the utility model provides a kind of workpiece switching mechanism, and this switching mechanism is applicable to the bottle blowing machine that adopts two step method, this switching mechanism can realize turning over the function of bottle equally, and it comprises workbench 1; Be vertically set on the central rotating shaft S on the workbench 1; Be fixedly installed on ring cam set spare 2 on the workbench 1 around central rotating shaft S, ring cam set spare 2 upper edge circumference are provided with the cam path 23 of annular, and this cam path 23 has overhead cam surface and following cam face; And be installed in rotating disk 11 on the central rotating shaft S; This switching mechanism also comprises the upset assembly, and this upset assembly comprises: mount pad 6 is fixedly mounted on the downside of rotating disk 11; Tooth bar 5, be arranged in the mount pad 6, rotating disk 11 is provided with and is suitable for the tooth bar moving conduit that tooth bar 5 moves up and down, for tooth bar 5 can be moved up and down in this tooth bar moving conduit, the lower end side of tooth bar 5 is to being provided with roller 30, this roller 30 is arranged in cam path 23, tooth bar 5 along with roller 30 in cam path 23 motion and move up and down; Gear shaft 10 is arranged in the mount pad 6, and is vertical with tooth bar 5, and has the gear part 3 that is meshed with described tooth bar 5, is rotated under the drive that moves up and down of tooth bar 5; Clamp structure, it comprises: manipulator mount pad 9 and the manipulator 8 that is connected with this manipulator mount pad 9, wherein, manipulator mount pad 9 is fixed on an end in gear shaft 10 outsides, manipulator 8 is installed in the outboard end of manipulator mount pad 9, and manipulator 8 can be used for clamping bottle base or bottle, and manipulator mount pad 9 rotates along with the rotation of gear shaft 10, overturn thereby drive manipulator 8, realize turning over base or turning over the bottle action of bottle blowing machine.
Bottle blowing machine is when turning over base or turning over bottle, rotating disk 11 rotates under the drive of actuating unit, mount pad 6 is along with rotating disk 11 rotates, thereby promoting roller 30 by tooth bar 5 and roller shaft 31 moves in cam path 23, described roller 30 can be a bearing, at this moment, roller shaft 31 is along with this bearing moves together, tooth bar 5 is along with the motion of roller shaft 31 moves up and down, tooth bar 5 meshes with the gear part 3 of gear shaft 10, and then driven gear axle 10 overturns upset drive manipulator mount pad 9 upsets of gear shaft 10, and then manipulator 8 is overturn, realize that bottle or the bottle base 7 on the manipulator 8 turns over turnback.
Can see from the left-half of Fig. 2, when bottle or bottle base 7 are in the state that opening makes progress, roller 30 is in the minimum point of cam path 23, when roller 30 moves among Fig. 1 position shown in the right half part in cam path 23, when promptly moving to the peak of cam path 23, tooth bar 5 also rises to peak along with the motion of roller shaft 31, rotates accordingly with the engagement drive manipulator mount pad 9 and the manipulator 8 of hour rack 5 with gear shaft 10, finally make bottle or bottle base 7 turn over turnback, Open Side Down.Finish after the once inside out, roller 30 continues to rotate in cam path 23, driving tooth bar 5 moves downward, gear shaft 10, manipulator mount pad 9 and manipulator 8 rotate accordingly simultaneously, finally, roller 30 is got back to the minimum point of cam path 23, and the position recovering of manipulator 8 is ready to complete and turns over the bottle action next time.
Because only moving up and down of tooth bar 5 by the motion decision of roller 30, when rotating disk 11 velocities of rotation are very fast, turn over bottle or turn over base action and also can finish smoothly, can not appear at and of the prior artly cause turning over bottle because of the spring return is untimely or turn over the situation that the base action can not be finished, remedied since spring because of the flexible frequent defective that ruptures of taking place.
In fact, roller 30 can be the annular workpiece that can move in described cam path 23 arbitrarily, as long as its motion in cam path 23 can drive roller shaft 31 and carry out circular motion.
In addition, the upper surface of cam member 2 can have breach 24, and the width of this breach 24 is greater than the width of mount pad 6, thereby is convenient to installation or removal mount pad 6.
Fig. 3 is the cam member plan structure schematic diagram of the utility model preferred embodiment, as shown in Figure 3, ring cam set spare 2 in this switching mechanism can be the split type circular ring structure that cuts along cutting plane A-A, comprise first curved portions 21 and second curved portions 22 that removably connect, like this, will rotating disk 11 parts such as grade do not pull down and to pull down ring cam set spare 2.Wherein, cutting plane A-A can be parallel to the axis of ring cam set spare 2, and the axis that departs from ring cam set spare 2 as much as possible, like this, because the cut-off lines of two curved portions makes the handing-over slit of two curved portions be oblique line shape without the center of circle O of ring cam set spare 2, when roller 30 passes through this slit from cam path 23, cushioning effect is played in progressively transition, can reduce roller 30 caused vibrations through the slit of two curved portions the time.
The above is a preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
