Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag production, in particular to a material taking device. Background Art

[0002] For thin sheet products, such as packaging bags, newspapers, magazines, etc., after being manufactured by the production equipment, they are stacked and arranged into piles, and then need to be transported to the bundling equipment for bundling. After bundling, they are sent to the discharge area. There are usually two ways to automatically convey the stacks of sheet products. One is usually conveyed by conveyor belts, and the other is conveyed by clamping devices. The disadvantage of conveying by conveyor belts is that there is a risk of stacks tipping over and scattering during transportation, especially when the product surface is smooth and the product is soft and fluffy, it is more likely to tip over and scatter. When a clamping device is used, in order to clamp the product to the specified position, the clamping device needs to be reciprocating and movable, and is usually installed on a linear motion mechanism. In the prior art, the stroke of most linear motion mechanisms matches the length of the drive component. A longer stroke requires a longer drive component, which makes the equipment occupy a large space and is limited in use in many occasions. For the production and preparation of packaging bags, it takes a long stroke to clamp the stack of packaging bags to the bundling equipment and then clamp it to the discharging equipment after bundling. The linear motion mechanism used in the current packaging bag production equipment is difficult to meet production needs. Utility Model Content

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0026] Example 1

[0027] The material taking device includes a linear reciprocating motion mechanism and a clamping device arranged on the linear reciprocating motion mechanism, such as Figure 1 As shown, the linear reciprocating motion mechanism comprises a first reciprocating motion mechanism 1 and a second reciprocating motion mechanism 2. The strokes of the first reciprocating motion mechanism 1 and the second reciprocating motion mechanism are superimposed, and the clamping jaw device 3 is arranged on the second reciprocating motion mechanism.

[0028] like Figure 2-3 As shown, the first reciprocating motion mechanism 1 includes a first slide rail 101 , a second slide rail 102 , a first synchronous belt fixing block 103 , a second synchronous belt fixing block 104 , a synchronous belt 105 , a rotating shaft 106 and a driving mechanism 107 .

[0029] The first slide rail 101 and the second slide rail 102 are arranged in parallel. The two slide rails can be formed on the same material or fixedly connected to form a double-layer slide rail by a connecting piece. The figure uses a slide rail connecting plate 120 for fixed connection. The first slide rail 101 is slidably connected to the frame. Figure 1 The slider and the slide rail are matched and connected. The first slider 108 is arranged on the first slide rail 101, and the first slider 108 is fixed on the frame through a mounting plate.

[0030] A rotating shaft 106 is fixedly arranged at both ends of the double-layer slide rail, and the rotating shaft is installed on the bearing seat. The synchronous belt 105 is installed on the rotating shaft 106 at both ends, and the driving mechanism 107 is used to drive the rotating shaft 106 to rotate. The rotating shaft on either side can be the driving side. The bearing seat and the driving mechanism 107 are fixedly connected to the first slide rail 101 and the second slide rail 102. The bearing seat and the driving mechanism 107 shown in the figure are installed on the slide rail connecting plate 120. The driving mechanism 107 can adopt a DC motor, a drive motor, a servo motor, etc.

[0031] The first synchronous belt fixing block 103 and the second synchronous belt fixing block 104 are fixedly arranged at the bisection of the synchronous belt 105, the first synchronous belt fixing block 103 is also fixedly connected to the frame, and the second synchronous belt fixing block 104 is slidably connected to the second slide rail 102. In the attached figure 3, the second synchronous belt fixing block 104 is fixedly connected to the second slider 109, and the second slider 109 is slidably connected to the slide rail 102, so that the second synchronous belt fixing block 104 is slidably connected to the second slide rail 102.

[0032] The second reciprocating motion mechanism 2 is arranged on the second synchronous belt fixing block 104, and a clamping device 3 is installed on the reciprocating motion part of the second reciprocating motion mechanism 2. The second reciprocating motion mechanism 2 can be various conventional reciprocating linear motion mechanisms such as a cam mechanism, a connecting rod mechanism, a reciprocating cylinder, a hydraulic cylinder, an electric cylinder, a belt mechanism, a gear rack mechanism, etc. In order to facilitate installation, a shift sliding plate 201 can be provided, and the shift sliding plate 201 is fixedly connected to the second slider, and the second reciprocating motion mechanism 2 is arranged on the shift sliding plate 201. Figure 4 The second reciprocating motion mechanism 2 adopts a slide block driven by a cylinder. The cylinder and the slide rail are installed on a shift sliding plate 201 , and the shift sliding plate 201 is fixedly arranged on the second slide block 109 .

[0033] The working process of the linear reciprocating motion mechanism: the left side of the observer facing the figure is the left side of the figure, and the right side is the right side of the figure. Figure 6As shown, when the initial position is state 1, the first slider is at the left limit of the first slide rail, and the second slider is at the right limit of the second slide rail. Because the first synchronous belt fixing block clamps the displaced synchronous belt and is fixed on the mounting plate, the synchronous belt as a whole cannot rotate, and the driving motor causes the driving side shaft to rotate counterclockwise. Under the action of the counterclockwise rotation of the active side synchronous wheel, the distance between the active side synchronous wheel and the first synchronous belt fixing block decreases, and the distance between the passive side synchronous wheel and the second synchronous belt fixing block also decreases at the same speed, causing the first slide rail to slide to the left in the first slider, and the second slider also slides to the left in the second slide rail, reaching the position of state 2; the driving motor causes the driving side shaft to rotate clockwise. Under the action of the clockwise rotation of the active side synchronous wheel, the distance between the active side synchronous wheel and the first synchronous belt fixing block increases, and the distance between the passive side synchronous wheel and the second synchronous belt fixing block also increases at the same speed, causing the first slide rail to slide to the right in the first slider, and the second slider also slides to the right in the second slide rail, returning to the position of state 1.

[0034] The clamping device 3 can adopt existing mechanical clamping claws, such as pneumatic fingers, which can clamp and release the packaging bag product through movement.

[0035] The specific structure of the clamping device of this embodiment is as follows Figure 5 As shown, the clamping jaw device 3 includes a clamping jaw 301 , a clamping jaw supporting plate 302 and a clamping jaw lifting mechanism 303 . The clamping jaw 301 is arranged on the clamping jaw supporting plate 302 , and the clamping jaw lifting mechanism is used to realize the lifting and lowering of the clamping jaw supporting plate 302 .

[0036] The clamp 301 includes a clamp execution arm 3011, a clamp swing arm 3012, a clamp connection arm 3013 and a clamp driving mechanism 3014; a clamp bracket 304 is arranged on the clamp support plate 302, one end of the clamp swing arm 3012 is hinged to the clamp bracket 304, and the other end is connected to one end of the clamp connection arm 3013 through a rotating shaft 3016, and the other end of the clamp connection arm 3013 is connected to the middle part of the clamp execution arm 3011 through an eccentric shaft 3015, and the length of the clamp connection arm 3013 can be changed by adjusting the angle of the eccentric shaft, and the telescopic rod of the clamp driving mechanism 3014 is connected to the rotating shaft 3016 to drive the clamp to open and close. When the stroke of the clamp driving mechanism remains unchanged, the clamping and closing size of the material taking clamp can be adjusted to achieve the best clamping force for grabbing products of different thicknesses.

[0037] The clamping jaw driving mechanism 3014 can adopt a pneumatic cylinder, a hydraulic cylinder or an electric cylinder.

[0038] The clamping jaw lifting mechanism 303 is installed on the second reciprocating motion mechanism 2. The clamping jaw lifting mechanism 303 can be a cylinder, a hydraulic cylinder, an electric cylinder, a gear rack transmission mechanism, a linear motor or a nut screw mechanism. The attached figure adopts a slider lifting mechanism, and the lifting slider 3031 and the lifting cylinder 3032 are installed on the clamping jaw mounting plate 3033, and the clamping jaw mounting plate 3033 is fixedly set on the slider of the second reciprocating motion mechanism. The lifting rail 3034 is installed on the clamping jaw supporting plate 302, and the piston rod of the lifting cylinder 3035 is connected to the clamping jaw supporting plate.

[0039] The front end of the clamping claw support plate 302 is in the shape of a fork and is arranged opposite to the clamping claw execution arm 3011, so as to facilitate the insertion of the bottom of the product from the gap of the support rod carrying the product.

[0040] A clamping plate bracket is provided at the end of the clamping jaw actuator arm 3011, and a clamping plate 3017 is provided on the clamping plate bracket. The clamping plate 3017 can swing within a certain range so that the clamping plate is parallel to the clamping jaw support plate at different heights, so as to better clamp the product. The clamping plate 107 can be detachably mounted on the clamping plate bracket and can be quickly replaced to be suitable for products of different widths.

[0041] The clamping device 3 further comprises a clamping push plate 305, which is arranged on the clamping support plate 302 below the clamping actuator arm 3011. The clamping actuator arm 3011 has a structure for avoiding interference.

[0042] During operation, the clamping claw lifting mechanism starts to reach the product grabbing height, the first reciprocating mechanism and the second reciprocating mechanism move the clamping claw device to the product grabbing position, the clamping claw device enters the product clamping area, and the product pushing plate can push the product flat in the process of the clamping claw entering the product clamping area or prevent the product from sliding under the action of the clamping force during the clamping process. The clamping claw driving mechanism closes the clamping claw device to clamp the product, the first reciprocating mechanism and the second reciprocating mechanism move the clamping claw device to the bundling position, the clamping device is lifted and lowered to the product bundling height, and after waiting for the bundling to be completed, the first reciprocating mechanism and the second reciprocating mechanism bring the clamping claw device to the product unloading position, the clamping claw driving mechanism retreats, the clamping claw device opens, the first reciprocating mechanism makes the clamping claw device run to the product complete exit position, and the unloading is completed. The clamping claw driving mechanism closes the clamping claw device, the clamping claw lifting mechanism retreats to the standby position, and the first reciprocating mechanism and the second reciprocating mechanism move the clamping claw device to the standby position, waiting for the next material pickup.
