Description

Technical Field

[0001] The utility model relates to the field of bag making, and specifically to a bag part station transfer device. Background Art

[0002] Bag making production is mainly used to manufacture non-rigid containers, such as bags made of paper, plastic, aluminum foil or other materials. These bags have an opening for loading the products to be packaged and are essential containers in the packaging steps of many product production links.

[0003] For the convenience of production, the bag making production line is usually introduced into the product production line, and a station transfer device is adopted on the conveying structures of the two production lines to move the bag parts to the next process. For example, in a mask production line, masks can be quickly bagged and packed.

[0004] The packaging bags used for masks have a plastic film on one side and paper on the other side. The transfer of such bag parts usually adopts the form of a suction cup with a vacuum generator. However, the use of a vacuum suction cup requires a large investment in equipment. And the bag parts with plastic film itself have a good contact and matching property with the suction cup, and the product situation of the bag parts is relatively simple. Therefore, the use of a vacuum suction cup easily leads to excessive investment but redundant functions, and also requires a large investment in debugging and maintenance. Therefore, a more suitable station transfer device for corresponding bag parts is needed to solve the current problems. Summary of the Utility Model

[0005] In view of the above problems, the utility model provides a bag part station transfer device, the structure of which includes a frame and a base installed on the frame through a moving component. A slide rail is provided on the frame, the base is slidably installed on the slide rail, a cylinder is provided on the base, a transfer seat is provided on the push arm of the cylinder, and an adsorption component is provided below the transfer seat. The adsorption component includes a suction cup for adsorbing workpieces; an inner cavity is provided in the suction cup and the opening of the inner cavity is located at the bottom end of the suction cup for contacting the workpiece to form a closed chamber; the adsorption component further includes a movable disk, and the movable disk is connected to the suction cup through a linkage for driving the edge of the suction cup to tilt up and reset.

[0006] Further, an adjusting column is provided at the top end of the suction cup, and the suction cup is installed on the transfer seat through the adjusting column. The movable disk is slidably nested on the adjusting column; an electromagnetic push rod is provided on the transfer seat, and the electromagnetic push rod is connected to the movable disk for driving the movable disk to move axially on the adjusting column.

[0007] Further, a belt ring is provided at the bottom edge of the outer wall of the suction cup, and the belt ring is connected to the linkage. When the movable disk moves, the linkage drives the edge of the suction cup to move along with it through the belt ring.

[0008] Furthermore, support ribs are provided on the outer wall of the suction cup from top to bottom. There is a gap between the support ribs and the belt loop, and the support ribs and the belt loop are connected by outwardly protruding extrusion ribs.

[0009] Furthermore, the suction cup is a ribbed suction cup. A flat rib extending downward is provided on the inner top surface of the suction cup. The flat rib is connected to the side surface of the suction cup and forms a connecting beam; the horizontal height of the bottom end of the connecting beam is located within the gap between the support ribs and the belt loop.

[0010] Furthermore, the belt loop extends downward to the bottom of the edge of the suction cup. The belt loop subjected to upward tension uses the connection point between the top end of the belt loop and the suction cup as a fulcrum to lever the bottom of the suction cup.

[0011] Furthermore, the moving assembly includes belt wheels separately provided on both sides of the frame and a transmission belt nested on the belt wheels. The transmission belt is connected to the machine base, and one of the belt wheels is connected to the motor.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The utility model uses a ribbed differential pressure suction cup to adsorb the workpiece, and an active disk driven by an electric push rod and a linkage member are provided on the suction cup to drive the edge of the suction cup to tilt up, so that it is more convenient for the suction cup to automatically adsorb and release the adsorption of the bag part. Thus, the differential pressure suction cup is used to replace the vacuum suction cup, reducing the system investment of the vacuum suction cup on the basis of achieving the required functions of the suction cup.

[0014] 2. The utility model is provided with a belt loop at the edge of the suction cup, and the active disk is connected to the belt loop through a linkage member. Moreover, the belt loop extends downward to the bottom of the edge of the suction cup. The belt loop subjected to upward tension uses the connection point between the top end of the belt loop and the suction cup as a fulcrum to lever the bottom of the suction cup. Therefore, when releasing the adsorption of the suction cup in the adsorption state, it can better drive and lift the edge of the suction cup to release the adsorption, facilitating the work of the suction cup.

[0015] 3. The utility model is provided with support ribs on the upper part of the suction cup to stabilize the shape of the upper part of the suction cup, thereby slowing down the influence on the upper part of the suction cup when the belt loop and the edge of the suction cup are lifted, reducing the amplitude of deformation of the upper part of the suction cup being lifted together. And when the edge of the suction cup is lifted, the extrusion ribs are used to drive the support ribs to squeeze inward towards the suction cup to balance the deformation of the upper part of the suction cup being lifted together.

DETAILED DESCRIPTION

[0021] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] Embodiment, the utility model provides a bag station transfer device, such as Figures 1-4 As shown: its structure includes a frame 1 and a machine base 6 mounted on the frame 1 through a moving component, a slide rail 5 is provided on the frame 1, the machine base 6 is slidably mounted on the slide rail 5, and the moving component is used to drive the machine base 6 to move on the slide rail 5, and the moving component includes pulleys 2 arranged on both sides of the frame 1 and a transmission belt 3 nested on the pulley 2, the transmission belt 3 is connected to the machine base 6, and the pulley 2 at one end is connected to the motor 4, and a cylinder 7 is provided on the machine base 6, the cylinder 7 is vertically arranged and works downward, a transfer seat 8 is provided on the push arm of the cylinder 7, and an adsorption component 9 is provided below the transfer seat 8, the pulley 2 is driven by the motor 4 to rotate and then drive the transmission belt 3 to move, and the machine base 6 fixed with the transmission belt 3 synchronously follows and moves on the slide rail 5, so that the adsorption component 9 switches the workstation;

[0023] The adsorption assembly 9 includes a suction cup 91 for adsorbing the workpiece and an adjustment column 92 provided at the top of the suction cup 91. The suction cup 91 is mounted on the transfer seat 8 through the adjustment column 92. The suction cup 91 is provided with an inner cavity, and the opening of the inner cavity is located at the bottom of the suction cup 91, which is used to contact with the workpiece to form a closed chamber, so as to adsorb the surface of the workpiece.

[0024] In this embodiment, the adsorption assembly 9 further includes a movable disk 93 and an electromagnetic push rod 95. The movable disk 93 is slidably nested on the adjusting column 92. The electromagnetic push rod 95 is installed on the transfer seat 8. The electromagnetic push rod 95 is connected to the movable disk 93 to drive the movable disk 93 to move axially on the adjusting column 92. The movable disk 93 is connected to the suction cup 91 through a linkage 94 to drive the edge of the suction cup 91 to make the edge of the suction cup 91 warp and reset. Correspondingly, a belt ring 91b is provided at the bottom edge of the outer wall of the suction cup 91. The linkage 94 adopts an annular structure. The belt ring 91b is connected to the linkage 94. When the movable disk moves, the linkage 94 drives the edge of the suction cup 91 to move along through the belt ring 91b;

[0025] Moreover, the suction cup 91 used in this embodiment is a ribbed suction cup 91. A flat rib 91a extending downward is provided on the inner top surface of the suction cup 91. The flat rib 91a is connected to the side surface of the suction cup 91 and forms a connecting beam. In order to reduce the lifting amplitude of the suction cup 91 and prevent the flat rib 91a from being affected when the suction cup 91 is lifted, a support rib 91c is provided on the outer wall of the suction cup 91 from top to bottom. The support rib 91c is used to stabilize the shape of the upper part of the suction cup 91. There is a gap between the support rib 91c and the belt ring 91b. And the horizontal height of the bottom end of the connecting beam is located within the gap between the support rib 91c and the belt ring 91b, so as to slow down the influence on the upper part of the suction cup 91 when the belt ring 91b and the edge of the suction cup 91 are lifted, and reduce the amplitude of the deformation of the upper part of the suction cup 91 being lifted together;

[0026] Moreover, the support rib 91c and the belt ring 91b are connected through an outwardly protruding extrusion rib 91d. Thus, when the edge of the suction cup 91 is lifted, the rising belt ring 91b pushes the extrusion rib 91d inward, and the extrusion rib 91d drives the support rib 91c to squeeze inward the suction cup 91 to balance the deformation of the upper part of the suction cup 91 being lifted together;

[0027] Moreover, the belt ring 91b extends downward to the bottom of the edge of the suction cup 91. The belt ring 91b subjected to upward pulling force uses the connection point between the top end of the belt ring 91b and the suction cup 91 as a fulcrum to lever the bottom of the suction cup 91. Thus, when releasing the adsorption of the suction cup 91 in the adsorption state, the edge of the suction cup 91 can be better driven.

[0028] In specific implementation, a suction cup 91 with six support ribs 91c and a ring 91b is adopted. Three of the rings 91b are connected to a linkage 94. The electric push rod drives the movable plate 93 to rise. The linkage 94 pulls the ring 91b on the suction cup 91 upward, thereby lifting the edge of the suction cup 91 to make the edge upturned, so that the inner cavity below the suction cup 91 can leak air through the side. Then the suction cup 91 descends to contact the bag piece and continues to press downward, making the non-upturned part further fit the bag piece to compress the size of the inner cavity. At the same time, the flat rib 91a presses down the part of the bag piece located in the inner cavity. Subsequently, the electric push rod drives the movable plate 93 and the linkage 94 to descend, making the upturned part of the suction cup 91 contact the bag piece downward, so that the whole suction cup 91 contacts the bag piece in a compressed state, forming a negative pressure in the inner cavity to adsorb the bag piece. Then the air cylinder 7 contracts to lift the bag piece, and the adsorption assembly 9 is driven by the moving assembly to move to the next station, and then the air cylinder 7 descends;

[0029] At this time, the electric push rod drives the movable plate 93 to rise, and the linkage 94 pulls the ring 91b upward. The ring 91b uses the connection point between the top of the ring 91b and the suction cup 91 as a fulcrum to lever the bottom of the suction cup 91, so as to upturn the part where the edge of the suction cup 91 contacts the bag piece, making the inner cavity communicate with the external atmosphere to release the adsorption of the bag piece. Thus, the operations of adsorbing, picking up, deflating and placing the bag piece are carried out, without the need to additionally adopt equipment such as a vacuum generator.

[0030] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combinations of these technical features do not conflict, they should all be considered to be within the scope described in this specification.
