Description

Technical Field

[0001] The present invention relates to the technical field of abdominal pad production equipment, and more particularly to a sewing unit for abdominal pad processing. Background Art

[0002] During human surgery, medical personnel need to use abdominal pads to wipe the blood on surgical incisions and surgical instruments to facilitate seeing the relevant parts of the human body and perform the surgery accurately. Therefore, the demand for this in hospitals is increasing year by year, and the production efficiency of manufacturers needs to be improved along with the demand. At present, the production process of abdominal pads is replaced by automated production. The automated production equipment must include a conveying mechanism, a folding mechanism and a sewing mechanism. The present invention relates to the sewing mechanism in automated production, and the sewing unit in the present invention cooperates with the folding processing device. The sewing mechanism is an important mechanism for determining the quality of abdominal pads in automated assembly line production. The current abdominal pads need to be folded first, then labeled, and finally sewn during the production process. As we all know, a complete and qualified abdominal pad has two or more layers. It can be an abdominal pad that is folded in half and then processed and sewn, or multiple abdominal pads can be stacked and processed. Sewing, wherein the corresponding folding edge includes the two sides of the abdominal pad after being folded in half, and the existing sewing methods are divided into two types, one is the traditional manual production, manually pushing the folded edge and the abdominal pad after the label tape into the sewing machine for pedal sewing machine sewing, this sewing method is prone to uneven sewing and low sewing efficiency. The other type is automated production, in which the folded edge and the abdominal pad after the label tape are transported to the bottom of the sewing machine unit by a transfer hand or a conveyor belt, and then the abdominal pad is pulled by a pulling hand on one side to try sewing, and after sewing is completed, it is transported to a collection box by a conveyor belt. In this sewing method, the abdominal pad is prone to position displacement during the transmission process, resulting in uneven subsequent sewing, and after sewing is completed, the abdominal pad cannot be neatly stacked by direct transmission through the conveyor belt, resulting in subsequent manual picking up of the finished product being too large, and causing problems such as low production efficiency and too high finished products. Summary of the invention

[0003] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a sewing unit for abdominal pad processing with precise sewing, high sewing efficiency and neat material picking and stacking, so as to overcome the above-mentioned defects in the prior art.

A first translational power source is also provided on one side of the clamping arm, and the first translational power source drives the group of clamping arms to move on the horizontal plane, so that the clamping arms of the group calibrate the corresponding folded edges of the belly pad on the folding processing device; a second translational power source is provided on one side of the crossbeam, and the second translational power source drives the crossbeam to move on the horizontal plane, so that the two groups of clamping arms are close to or away from the belly pad on the folding processing device after the label tape is loaded and the folded edges are formed, and the two groups of clamping arms are used to clamp the belly pad on the folding processing device after the label tape is loaded and the folded edges are formed;

[0006] The transfer mechanism comprises a slide plate, an upper pressing plate and two vertical plates, the upper pressing plate and the two vertical plates are all located at the bottom of the slide plate, the two vertical plates are arranged horizontally with each other, and there is a pressure space between the two vertical plates, the upper pressing plate is located directly above the pressure space, a third translational power source and a fourth translational power source are provided on the slide plate, the third translational power source drives the slide plate to move in the horizontal direction so that the upper pressing plate is located above the belly pad between the clamping arm and the sewing platform, and the pressure space is located below the belly pad between the clamping arm and the sewing platform, and the fourth translational power source drives the upper pressing plate to move in the vertical direction so that the upper pressing plate presses the belly pad between the clamping arm and the sewing platform into the pressure space;

[0007] The material picking mechanism includes multiple groups of pressing rods, and a material receiving door is provided on the base on one side of the sewing machine. The multiple groups of pressing rods are symmetrically arranged on both sides of the movement track of the slide board, and the multiple groups of pressing rods are all located above the material receiving door. The multiple groups of pressing rods are respectively provided with corresponding pressing cylinders, and the pressing cylinders drive the pressing rods to move in the vertical direction, so that the pressing rods press to open the material receiving door and the abdominal pad located above the material receiving door falls down.

[0008] Furthermore, the two groups of clamping arms include an upper sewing clamp and a lower sewing clamp, the upper sewing clamp includes a first vertical plate and a protrusion, the protrusion is located at the bottom of one side of the first vertical plate, the lower sewing clamp includes a second vertical plate and a sewing pressure plate, the sewing pressure plate is horizontally located at the bottom of one side of the second vertical plate, and a fifth translational force source is also provided on one side of the second vertical plate where the sewing pressure plate is located, the fifth translational force source drives the first vertical plate to move in the vertical direction so that the protrusion presses the folded edge of the abdomen pad between the protrusion and the sewing pressure plate or separates from the sewing pressure plate.

[0009] Furthermore, the upper pressure plate is an inverted L-shape, comprising a horizontal pressing portion and a vertical insertion portion, a limit plate parallel to the horizontal pressing portion is provided on the inner side surface of the vertical insertion portion, a sliding column is provided between the limit plate and the horizontal low-pressure portion, and a buffer spring is sleeved on the sliding column.

The eighth translational power source drives the sewing machine to move in a horizontal direction so that the needle of the sewing machine is sewed along the folded edge of the abdominal pad.

[0013] The beneficial effects of the present invention are as follows: 1. The two sets of clamping arms move to the folding processing device to clamp the abdominal pad after the folding and label tape loading and transfer it to the sewing platform for sewing. During the clamping process, the two sets of clamping arms always clamp the two folding edges of the abdominal pad accurately and stably, avoiding the two folding edges from falling off or shifting during the transfer process, thereby affecting the subsequent sewing. That is, the setting of the two sets of clamping arms can improve the efficiency of abdominal pad transportation and improve the qualified rate of abdominal pads;

[0014] 2. The sewing machine can move forward, backward, left and right in the horizontal direction to achieve the folding and sewing of the abdominal pad. The forward and backward movement is the process of sewing, and the left and right movement is to calibrate the sewing needle to the folding and sewing position. Compared with the method in the prior art where the sewing machine does not move but the abdominal pad moves, the sewing method in this scheme can keep the sewing needle on the folding edge during sewing, and the sewing is neat and efficient.

[0015] 3. The sewn belly pad is pressed into the compressed space between the two vertical plates by the transfer mechanism. The belly pad pressed into the compressed space is clamped by the two vertical plates so that it does not fall off. The belly pad is transferred to the material receiving door by the transfer mechanism. The material picking mechanism presses down and releases the vertical plate so that the belly pad falls off to the material receiving door. The material receiving door is opened by pressing, and the belly pad on the material receiving door falls down stably and neatly and is stacked in the collection box.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0024] The embodiments of the present invention are further described in detail below with reference to the accompanying drawings:

[0025] Since the current abdominal pad needs to be folded first, then labeled, and finally sewn during the production process, it is well known that a complete and qualified abdominal pad has two or more layers. It can be a abdominal pad that is folded in half and then processed and sewn, or multiple abdominal pads are stacked and then processed and sewn. There are two existing sewing methods. One is the traditional manual production, in which the abdominal pad with the folded edges and the labeled tape is manually pushed into the sewing machine 2 for pedal sewing. This sewing method is prone to uneven sewing and low sewing efficiency. The other is automated production, in which the folded edges and the labeled tape are manually pushed into the sewing machine 2 for pedal sewing. The belly pad after the marking tape is transported to the bottom of the sewing machine group 2 by a transfer hand or a conveyor belt, and then the belly pad is pulled by a pulling hand on one side for trial sewing. After the sewing is completed, it is transported to a collection box by a conveyor belt. In this sewing method, the belly pad is prone to position deviation during the transmission process, resulting in uneven subsequent sewing, and the belly pad cannot be neatly stacked by direct transmission through the conveyor belt after sewing, resulting in the subsequent manual picking of the finished product being too large, and causing low production efficiency, and the finished product is too high. Therefore, the present invention designs such a sewing unit for processing the belly pad, and the specific structure is as follows Figure 1 As shown, it includes a frame 1, on which a sewing machine 2 is included, and the sewing machine 2 is used to sew the folded abdominal pad fabric. The frame 1 also includes a clamping mechanism 3, a transfer mechanism 4 and a material picking mechanism 5, and the transfer mechanism 4 is located between the clamping mechanism 3 and the material picking mechanism 5 (the present invention has two sets of frames 1, one set of frames 1 is used to carry the sewing machine 2 and the clamping mechanism 3, and the other set of frames 1 is used to carry the transfer mechanism 4 and the material picking mechanism 5, and the two sets of frames 1 are arranged side by side). Figure 3 As shown, the clamping mechanism 3 includes a crossbeam 31 and two groups of clamping arms 32. The crossbeam 31 is horizontally located on the sewing platform 21. The two groups of clamping arms 32 are horizontally arranged on the same side of the crossbeam 31, and the two groups of clamping arms 32 are perpendicular to the crossbeam 31. A first translational power source 33 (motor or cylinder, motor and transmission belt transmission are used in this solution) is also provided on one side of any group of clamping arms 32. The first translational power source 33 drives the group of clamping arms 32 to move on a horizontal plane so that the group of clamping arms 32 calibrates the corresponding folded edge of the abdominal pad on the folding processing device, as shown in FIG. Figure 2As shown, a second translational power source 6 (motor or cylinder, in this solution, a motor and a screw drive are used) is provided on one side of the crossbeam 31. The second translational power source 6 drives the crossbeam 31 to move on a horizontal plane, so that the two groups of clamping arms 32 are close to or away from the belly pad after the label tape is loaded and folded on the hemming processing device. The two groups of clamping arms 32 are used to clamp the belly pad after the label tape is loaded and folded on the hemming processing device. The two groups of clamping arms 32 include a sewing upper clamping plate 321 and a sewing lower clamping plate 322. The upper sewing clamping plate 321 includes a first vertical plate 3211 and a protrusion 3212, the protrusion 3212 is located at the bottom of one side of the first vertical plate 3211 (the protrusion 3212 and the first vertical plate 3211 are perpendicular to each other to form an L shape, and the protrusions 3212 of the two groups of support arms face each other), and the lower sewing clamping plate 322 includes a second vertical plate 3221 and a sewing pressing plate 3222, the sewing pressing plate 3222 is horizontally located at the bottom of one side of the second vertical plate 3221 (the sewing pressing plate 3 222 and the second vertical plate 3221 are perpendicular to each other to form an L shape, and the sewing pressing plates 3222 of the two sets of support arms face each other), and a fifth translational power source 323 (cylinder) is also provided on one side of the second vertical plate 3221 where the sewing pressing plate 3222 is located. The fifth translational power source 323 drives the first vertical plate 3211 to move in the vertical direction, so that the protrusion 3212 presses the folded edge of the abdominal pad between the protrusion 3212 and the sewing pressing plate 3222 or separates from the sewing pressing plate 3 222, its beneficial effect is: the two groups of clamping arms 32 move to the folding processing device to clamp the abdominal pad after the folding and label tape loading and transfer it to the sewing platform 21 for sewing. During the clamping process, the two groups of clamping arms 32 always clamp the two folded edges of the abdominal pad accurately and stably to avoid the two folded edges falling off or shifting during the transfer process, thereby affecting the subsequent sewing. That is, the setting of the two groups of clamping arms 32 can improve the transportation efficiency of the abdominal pad and improve the qualified rate of the abdominal pad.

A limit plate 9 parallel to the horizontal pressing portion 451 is provided on the inner side surface of the vertical insertion portion 452, and a sliding column 10 is provided between the limit plate 9 and the horizontal low-pressure portion. A buffer spring is sleeved on the sliding column 10 (the buffer spring plays a buffering role to prevent the upper pressure plate from being hit by excessive force on the limit plate 9); a sixth translational power source 11 (cylinder) is provided on any vertical plate 42, and the sixth translational power source 11 drives any vertical plate 42 to move on the horizontal plane to increase the pressurized space 7.

[0027] like Figure 1As shown, the material picking mechanism 5 includes multiple groups of pressing rods 51, and a material receiving door 8 is provided on the base on one side of the sewing machine 2 (the material receiving door 8 in the present invention is two door panels hinged on the frame 1 at opposite sides, similar to an old-fashioned window), and multiple groups of pressing rods 51 are symmetrically arranged on both sides of the movement trajectory of the slide plate 41, and the multiple groups of pressing rods 51 are all located above the material receiving door 8 (the distance between the two pressing rods 51 opposite to each other on both sides of the movement trajectory of the slide plate 41 is greater than the width of the abdominal pad, so that the pressing rods 51 are not directly pressed on the abdominal pad when pressing), and corresponding pressing cylinders 52 are respectively provided on the multiple groups of pressing rods 51, and the pressing cylinders 52 drive the pressing The rod 51 moves in the vertical direction so that the pressing rod 51 presses to open the material receiving door 8 and the abdominal pad located above the material receiving door 8 falls down; its beneficial effects are: the abdominal pad after sewing is pressed into the compressed space 7 between the two vertical plates 42 by the transfer mechanism 4, and the abdominal pad pressed into the compressed space 7 is not separated by the clamping of the two vertical plates 42, and is transferred to the material receiving door 8 by the transfer mechanism 4, and the abdominal pad is separated from the material receiving door 8 by the picking mechanism 5 pressing downward and releasing the vertical plate 42, and the material receiving door 8 is opened by pressing, and the abdominal pad located on the material receiving door 8 falls stably and neatly and is stacked in the collection box.

[0028] like Figure 3 As shown, in order to achieve a better sewing effect and a neater sewing line, the side of the protrusion 3212 facing away from the first vertical plate 3211 and the side of the sewing pressing plate 3222 facing away from the second vertical plate 3221 are on the same vertical plane.

[0029] like Figure 1 As shown, the base is also provided with a seventh translational motive force source (cylinder or motor) and an eighth translational motive force source (cylinder or motor). The seventh translational motive force source drives the sewing machine 2 to move in the horizontal direction so that the sewing needle of the sewing machine 2 is calibrated with the folded edge of the abdominal pad. The eighth translational motive force source 12 drives the sewing machine 2 to move in the horizontal direction so that the sewing needle of the sewing machine 2 is sewed along the folded edge of the abdominal pad. The purpose is to enable the sewing needle of the sewing machine 2 to align with this side for sewing.

[0030] Working principle: First, the crossbeam 31 is driven by the power source to align the clamping arm 32 on the side away from the transfer mechanism 4 with one folded edge of the belly pad on the folding processing device, and then the clamping arm 32 on the side close to the moving mechanism is adjusted to align with the other folded edge of the belly pad on the folding processing device, and the clamping arm 32 on this side is driven by the power source to move on the crossbeam 31, and the distance between the two groups of clamping arms 32 is adjusted, and then the crossbeam 31 is driven by the power source to move forward and backward, so that the two groups of clamping arms 32 move to the belly pad of the folding processing device, and the sewing The upper surface of the lower clamping plate 322 is located on the bottom surface of the abdominal pad, and the bottom surface of the sewing upper clamping plate 321 is located on the upper surface of the abdominal pad. The cylinder drives the sewing upper clamping plate 321 to move downward to press the folded edge of the abdominal pad onto the sewing lower clamping plate 322, and then the crossbeam 31 moves back to its original position. The two sets of clamping arms 32 clamp the abdominal pad to the sewing platform 21. The sewing machine 2 first sews the center line of the abdominal pad. After the center line is sewn, the sewing machine 2 moves to one side or the clamping arm 32 moves to one side of the sewing platform 21 to align the sewing needle with the folded edge. When the two folded edges are sewn, the transfer mechanism 4 moves to the side of the clamping mechanism 3 under the drive of the cylinder. At this time, the upper pressing plate is higher than the clamping arm 32, and the two vertical plates 42 are lower than the clamping arm 32. Therefore, the upper pressing plate and the two vertical plates 42 are moved between the sewing platform 21 and the clamping arm 32, and the upper pressing plate moves downward. The limit plate 9 first presses against the upper surface of the outer vertical plate 42, and the cylinder continues to drive the upper pressing plate downward. The horizontal pressing portion 451 of the upper pressing plate acts on the limit plate 9, and the vertical insertion portion 45 2 presses the belly pad into the pressurized space 7, at which time the cylinder drives one vertical plate 42 to move toward the other vertical plate 42 to clamp the pressed belly pad, and then the upper pressing plate moves up to reset, and the cylinder drives the slide plate 41 to move above the material receiving door 8, and the two vertical plates 42 pull the belly pad to above the material receiving door 8, and the two vertical plates 42 are released, and the belly pad falls horizontally on the material receiving door 8. At this time, the pressing rod 51 presses downward to open the material receiving door 8, and the belly pad slides toward the middle as the material receiving door 8 opens to the collection box in the frame 1, so as to achieve neat stacking.

[0031] The above are only preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
