Description
Technical field
The invention belongs to the technical fields of vacuum crawl, and in particular to a kind of vacuum absorption device.
Background technology
It is storing in a warehouse, is being required for using mobile capture apparatus in logistics and baling line, capture apparatus is equipped with vacuum suction
Device, adsorbent equipment are equipped with multiple vacuum cups, and vacuum cup is a kind of band sealing lip, after being contacted with absorbate body
Formed a provisional sealing space, by take away or thin sealing space inside air, generate external and internal pressure difference and
A kind of pneumatic element to work.Object is lived by sucker suction, object is moved to the position needed, such as to plank or glass
The multiple sucker suctions of mobile needs in plank or the different location of glass, plank is lifted or is moved on to elsewhere, for not
The object of plane, such as tubing, it is necessary to the sucker with tubing radian same shape, more than sucker use by object
Surface limitation of different shapes.
China Patent Publication No. CN103072822A discloses a kind of flexible sponge sucker system, and sucker system includes
Spongy layer, unidirectional valve layer, airtight cavity and frame, unidirectional valve layer in airtight cavity with being set in frame, the lower part of airtight cavity
Each check valve (check-valves, or throttle valve) in unidirectional valve layer is connected, top is connected in the vacuum tube on frame,
Spongy layer is fixed below frame and at least provided with a bottom outlet, and multiple air holes are provided in unidirectional valve layer, each ventilative
At least one check valve is equipped in hole, the valve port of each check valve is corresponding with bottom outlet, and closed is fixed on bottom outlet inner end, each bottom
Hole forms a gas circuit with the valve port of corresponding check valve, and the effect of check valve is not sealed by workpiece to be drawn when bottom outlet
When stifled, the valve ball of corresponding check valve blocks valve opening to close corresponding gas circuit under the action of pull of vacuum, avoids closed chamber
Internal vacuum is destroyed, and so as to prevent the suction of other bottom outlets too small, workpiece only need to be with random one on spongy layer or more
A bottom outlet contact can be just sucked.This sucker system can meet the object of crawl different size, different shape and different volumes,
But since each bottom outlet needs to be correspondingly arranged a check valve, the valve ball of check valve using gravity steel ball, and bottom outlet quantity compared with
It is more, cause its complicated, assembling is cumbersome, of high cost, and weight is big.Further, since each bottom outlet needs to breathe freely with each
Hole, check valve or throttle valve correspond, and the location arrangements of the adsorption hole on spongy layer are very restricted.
At present, the sponge sucker system of the flexible in industry is in use, due to that will be suitable for different sizes or table
The workpiece of face shape, all suckers of sucker cannot be blocked all by workpiece under many operating modes, and primary when suction is design
Consideration, therefore to reduce loss of vacuum (suction losses), a non-return is correspondingly arranged in each sucker in design
Valve or throttle valve, when corresponding sucker is not blocked by workpiece, check-valves or throttle valve can play reduction loss of vacuum
Effect.This is the practice or perhaps technology prejudice of the industry.
