Description

Technical Field

[0001] The present invention relates to the technical field of production transportation, and in particular to a method for synchronously transporting film layers. Background Art

[0002] In the process of producing the liquid storage bag, since the liquid storage bag is formed by welding two film layers into one piece, a hose needs to be inserted between the two film layers before the two film layers are welded, and the two film layers need to be transported synchronously when inserting the hose.

[0003] In the prior art, when conveying two film layers, they are usually clamped and conveyed by two motors respectively. However, when the two motors receive the conveying instructions, they may be delayed and cannot convey the two film layers synchronously, which causes the two film layers to be misaligned during the insertion tube welding. Summary of the invention

[0004] The purpose of the present invention is to provide a method for synchronously conveying film layers, aiming to solve the problem of unstable synchronous conveying of film layers in the prior art.

[0005] The present invention is implemented in this way: the film layer synchronous conveying method comprises the following steps:

[0006] 1) Two clamps that move back and forth synchronously horizontally clamp two film layers respectively, the two clamps are arranged in a front-to-back spacing, and the two clamps are fixedly connected by a linkage rod, and the linkage rod is connected to a driving structure that drives the two clamps to move back and forth synchronously horizontally;

[0007] The clamp comprises a movable seat and a clamping strip arranged on the movable seat and movable vertically up and down, wherein the clamping strip and the movable seat are arranged vertically opposite to each other;

[0008] 2) driving the clamping strip to move downward to the moving seat, clamping the two film layers facing the moving seat, and using the driving structure to drive the linkage rod, so that the linkage rod drives the two moving seats to move forward synchronously and horizontally to a set distance;

[0009] 3) driving the clamping strip to move upward and separate from the moving seat, releasing the clamping of the two film layers, and using the driving structure to drive the linkage rod so that the linkage rod drives the two moving seats to move backward synchronously to a set distance;

[0010] 4) Repeat steps 2) and 3) to continuously and synchronously transport the two film layers forward.

[0011] Furthermore, the two moving seats are fixedly connected via a linkage rod, and the linkage rod is transmission-connected to the driving structure.

[0012] Further, a cylinder for driving the clamping strip to move up and down is provided on the moving seat. The cylinder is connected to the clamping strip through a telescopic shaft to drive the clamping strip to move up and down.

[0013] At both ends of the moving seat, there are limiting strips for limiting the up and down movement of the clamping strip. There is a sliding area arranged at intervals between the two limiting strips, and the clamping strip is located in the sliding area.

[0014] The limiting strip has a longitudinally arranged and inwardly recessed limiting chute. Both ends of the clamping strip are respectively inserted into the two limiting strips, and both ends of the clamping strip respectively abut against the inner side walls of the two limiting chutes.

[0015] Further, a guide rail frame for synchronously moving the gripper horizontally back and forth is connected to the gripper. A guiding frame for guiding the movement of the film layer is provided on the guide rail frame. The two guiding frames are respectively located between the two grippers, and the two grippers and the two guiding frames are arranged horizontally.

[0016] Further, there is a welding station between the two grippers for welding the rubber tube and the two film layers; there is a welding area arranged at intervals between the two guide rail frames, and the welding station is located in the welding area.

[0017] Further, a plurality of inserting and positioning jigs for inserting the rubber tube between the two film layers are provided between the two grippers. The plurality of inserting and positioning jigs are arranged on a transmission structure, and the driving structure drives the transmission structure to move so that the inserting and positioning jig with the rubber tube inserted is placed at the welding station.

[0018] Further, the transmission structure includes a chain for installing the inserting and positioning jig. The plurality of inserting and positioning jigs are arranged at intervals along the length direction of the chain. The chain is in transmission connection with the driving structure so that the driving structure drives the chain to drive the plurality of inserting and positioning jigs to rotate unidirectionally.

[0019] Further, the driving structure includes a moving head for driving the two grippers to move horizontally back and forth synchronously and a driving motor for driving the moving head to move horizontally back and forth.

[0027] When the clamping end face moves downward to the facing end face and the abutting block fits and abuts in the abutting groove to clamp the two film layers in an opposite direction, the top bead retracts into the telescopic cavity, and the protective ring extends and deforms towards the top bead after being squeezed;

[0028] When the clamping end face moves upward and separates from the facing end face and the abutting block and the abutting groove release the clamping of the two film layers, the outer side of the top bead is exposed above the protective ring, and the protective ring resumes its shape.

[0040] Refer to Figures 1-6 as shown, which is a preferred embodiment provided by the present invention.

[0041] The film layer synchronous conveying method comprises the following steps:

[0042] 1) Two clamps 100 that move back and forth synchronously horizontally clamp two film layers respectively, the two clamps 100 are arranged in a front-to-back spacing, and the two clamps 100 are fixedly connected by a linkage rod 300, and the linkage rod 300 is connected to a driving structure 200 that drives the two clamps 100 to move back and forth synchronously horizontally;

[0043] The clamp 100 includes a movable seat 101 and a clamping strip 102 disposed on the movable seat 101 and movable vertically up and down, and the clamping strip 102 and the movable seat 101 are arranged vertically opposite to each other;

[0044] 2) The driving clamp 102 moves downward to the moving seat 101, clamping the two film layers facing the moving seat 101, and the driving structure 200 drives the linkage rod 300, so that the linkage rod 300 drives the two moving seats 101 to move forward synchronously and horizontally to a set distance;

[0045] 3) The driving bar 102 is driven to move upward and separate from the moving seat 101, thereby releasing the clamping of the two film layers, and the driving structure 200 is used to drive the linkage rod 300, so that the linkage rod 300 drives the two moving seats 101 to move backward synchronously to a set distance;

[0046] 4) Repeat steps 2) and 3) to continuously and synchronously transport the two film layers forward.

[0047] The above-mentioned method for synchronous conveying of film layers clamps two film layers by two clamps 100. The clamps 100 use the clamping strips 102 and the movable seat 101 to clamp the two film layers in opposite directions, thereby improving the clamping stability of the two film layers by the clamps 100. The driving structure 200 is used to drive the linkage rod 300 to move back and forth synchronously horizontally, and then the linkage rod 300 drives the two clamps 100 to clamp the two film layers and move forward synchronously horizontally, thereby solving the problem of unstable synchronous conveying of film layers.

[0048] The two movable seats 101 are fixedly connected by a linkage rod 300, and the linkage rod 300 is transmission-connected to the driving structure 200; in this way, the driving structure 200 can drive the two movable seats 101 to move back and forth synchronously horizontally through the linkage rod 300, so that the two clamps 100 clamp the two film layers and move forward synchronously horizontally.

[0049] In this embodiment, a cylinder 103 for driving the clamping strip 102 to move up and down is provided on the movable seat 101. The cylinder 103 is connected to the clamping strip 102 through a telescopic shaft 104 to drive the clamping strip 102 to move up and down.

[0050] At both ends of the moving seat 101, there are limiting strips 105 for the up and down movement of the limiting clip strips 102. There is a sliding area arranged at a relative interval between the two limiting strips 105, and the clip strip 102 is located in the sliding area;

[0051] On the limiting strip 105, there is a longitudinally arranged and inwardly recessed limiting chute 106. The two ends of the clip strip 102 are respectively inserted into the two limiting strips 105, and the two ends of the clip strip 102 respectively abut against the inner side walls of the two limiting chutes 106.

[0052] The moving seat 101 drives the telescopic shaft 104 through the cylinder 103 to drive the clip strip 102 to move downward, and holds the two film layers in a clamping manner with the moving seat 101;

[0053] The limiting movement of the clip strip 102 is limited by the two limiting strips 105, so as to avoid deviation when the clip strip 102 moves downward to the moving seat 101, resulting in ineffective clamping of the two film layers;

[0054] The two limiting chutes 106 are respectively used to further limit the movement of the two ends of the clip strip 102, so as to improve the clamping effect of the clip strip 102 and the moving seat 101 on the two film layers.

[0055] In this embodiment, a guide rail frame 400 for the synchronous horizontal reciprocating movement of the gripper 100 is connected to the gripper 100. A guide frame 401 for guiding the movement of the film layer is provided on the guide rail frame 400. The two guide frames 401 are respectively located between the two grippers 100, and the two grippers 100 and the two guide frames 401 are horizontally arranged.

[0056] The gripper 100 is horizontally moved through the guide rail frame 400, which is convenient for improving the conveying of the film layer. The film layer passes through and is guided by the guide frame 401 to avoid looseness of the two film layers during movement.

[0057] There is a welding station between the two grippers 100 for welding the rubber tube and the two film layers; there is a welding area arranged at an interval between the two guide rail frames 400, and the welding station is located in the welding area; in this way, during the movement of the two film layers, a rubber tube can be inserted for welding.

[0058] In this embodiment, a plurality of tube inserting jigs 500 for inserting the rubber tube disposed between the two film layers are provided between the two grippers 100. The plurality of tube inserting jigs 500 are arranged on a transmission structure 600, and the driving structure 200 drives the transmission structure 600 to move, so that the tube inserting jig 500 inserted with the rubber tube is placed at the welding station.

[0059] When the driving structure 200 synchronously drives the transmission structure 600 and the linkage rod 300 to work, the linkage rod 300 drives the two film layers to move through the two clamps 100, and the transmission structure 600 drives the intubation fixture 500 to move;

[0060] When the driving structure 200 synchronously drives the transmission structure 600 and the linkage rod 300 to work, the two film layers and the intubation jig 500 move synchronously, so that the intubation jig 500 is synchronously inserted between the two film layers.

[0061] The transmission structure 600 includes a chain for installing the intubation jig 500. Multiple intubation jigs 500 are extended and arranged at intervals along the length direction of the chain. The chain is connected to the driving structure 200 so that the driving structure 200 drives the chain to drive multiple intubation jigs 500 to rotate unidirectionally. The driving structure 200 drives the chain to rotate and move unidirectionally, so that the rubber hose of the intubation jig 500 has time to insert, which facilitates the synchronous intubation work between the intubation jig 500 and the two membrane layers.

[0062] In this embodiment, the driving structure 200 includes a moving head 201 that drives the two clamps 100 to move back and forth horizontally synchronously and a driving motor 202 that drives the moving head 201 to move back and forth horizontally. The moving head 201 is provided with a fixed clamp 203 that clamps the linkage rod 300, and the fixed clamp 203 is fixedly connected to the linkage rod 300.

[0063] The driving machine drives the moving head 201 to move back and forth horizontally, and the moving head 201 drives the linkage rod 300 to move back and forth horizontally through the fixed clamp 203, and then drives the two clamps 100 to clamp the two film layers and transport them horizontally synchronously through the linkage rod 300.

[0064] In this embodiment, the movable seat 101 has an end surface 107 facing the film layer, and the end surface 107 has an abutment groove 108 which is concave inward and for the film layer to abut. The abutment groove 108 is provided with a plurality of top beads 109 which are longitudinally extended up and down, and the plurality of top beads 109 are arranged at intervals along the length direction of the abutment groove 108;

[0065] The top ball 109 is installed in the telescopic seat 110, and the outer side of the top ball 109 is exposed outside the top of the telescopic seat 110; the abutment groove 108 has a telescopic cavity 111 with a top opening, the telescopic seat 110 is located in the telescopic cavity 111, and the bottom of the telescopic cavity 111 is connected to the bottom of the telescopic seat 110 through an elastic member 112;

[0066] When the clamping strip 102 moves downward onto the movable seat 101 and clamps two film layers facing the movable seat 101, the clamping strip 102 presses the top bead 109 toward the telescopic cavity 111 through the film layer, and the top bead 109 retracts into the telescopic cavity 111;

[0067] When the clamping strip 102 moves upward and separates from the moving seat 101, releasing the clamping of the two film layers, the elastic member 112 in the telescopic cavity 111 pushes the telescopic seat 110 towards the top opening through the elastic force, so that the telescopic seat 110 drives the film layer upward through the top bead 109 until the bottom of the film layer separates from the abutting groove 108;

[0068] During the process that the driving structure 200 drives the linkage rod 300 to drive the two moving seats 101 to move backward synchronously, the abutting groove 108 reduces the frictional resistance between the film layer through the top bead 109.

[0069] Through the setting of the abutting groove 108, the two sides of the two film layers can be restricted to prevent the two film layers from being misaligned. The top bead 109 is used to reduce the frictional loss between the bottom of the film layer and the top of the abutting groove 108 when the moving seat 101 moves backward, increasing the protection of the bottom of the film layer.

[0070] In this embodiment, the clamping strip 102 has a clamping end face 113 facing the end face 107. The clamping end face 113 has an abutting block 114 protruding towards the abutting groove 108 and elastically deformed. The abutting block 114 and the abutting groove 108 are arranged longitudinally opposite to each other;

[0071] An elastically deformed protective ring 115 is provided on the top opening of the telescopic cavity 111. The protective ring 115 is arranged along the circumference of the top opening of the telescopic cavity 111, and the upper part of the protective ring 115 is exposed outside the top opening of the telescopic cavity 111;

[0072] When the clamping end face 113 moves downward to the end face 107, and the abutting block 114 is fitted and abutted in the abutting groove 108 to clamp the two film layers towards each other, the top bead 109 retracts into the telescopic cavity 111, and the protective ring 115 is deformed and extended towards the top bead 109 after being squeezed;

[0073] When the clamping end face 113 moves upward and separates from the end face 107, and the abutting block 114 and the abutting groove 108 release the clamping of the two film layers, the outside of the top bead 109 is exposed above the protective ring 115, and the protective ring 115 resumes its shape.

[0074] Through the sealing clamping between the abutting block 114 and the abutting groove 108, the misalignment between the two film layers can be reduced. By using the squeezing deformation of the protective ring 115, when the abutting block 114 presses against the film layer, the film layer will not have indentations due to being pressed at the top opening of the telescopic cavity 111.

[0075] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
