Technical Field

[0001] The utility model relates to the technical field of sewing, in particular to a multi-rope-end button sewing auxiliary device and a sewing machine using the same. Background Art

[0002] In the clothing manufacturing process, for the rope-end button sewing, generally, a single rope end is wound in a circle through manual folding, and then manually fed and sewn to the corresponding sewing position for button sewing. In the prior art, a sewing machine usually can only sew a single rope end at a time. Although there are various mechanized rope-end button sewing auxiliary devices in the prior art, usually only the efficiency or quality improvement of sewing a single rope end can be achieved. Summary of the Utility Model

[0003] The main purpose of the utility model is to propose a multi-rope-end button sewing auxiliary device, which realizes multi-rope-end button sewing in a single sewing of a sewing machine, aiming to solve the technical problem that only the efficiency or quality improvement of sewing a single rope end can be achieved in the prior art.

[0004] To achieve the above purpose, the utility model proposes a multi-rope-end button sewing auxiliary device, which includes an auxiliary side-position mechanism. The auxiliary side-position mechanism includes a side-position member and several partition members. The side-position member includes a first side-position member and a second side-position member. A sewing area is formed between the first side-position member and the second side-position member. The partition members are arranged between the first side-position member and the second side-position member. The sewing area is divided by the partition members along the feeding direction to form several sewing channels.

[0005] In this solution, the multi-rope-end button sewing auxiliary device is installed on a sewing machine. Taking a sewing channel directly opposite to the sewing needle of the sewing machine as the working channel, in a normal working process, multiple folded rope ends are fed and respectively placed in multiple sewing channels - the presser foot presses the rope ends in all sewing channels - the sewing work on the rope end in the working channel is completed - the next sewing channel is moved to the working channel for continuous sewing - the current sewing work is completed to obtain the sewn rope ends. In this solution, not only multi-rope-end button sewing is realized, but also it is beneficial to avoid sewing adhesion of multiple rope ends in a single sewing, achieving high-quality and high-efficiency button sewing work on multiple rope ends in a single sewing, with a high degree of mechanization.

[0006] In the prior art, in the button sewing process, it is customary to sew a single rope end, and there is less technology specifically for realizing the work of sewing multiple rope ends in a single sewing. Usually, only large-scale equipment on the production line is modified to form multiple sewing stations (in each station, a single sewing needle corresponds to a single rope end), with high costs. This solution breaks through the existing thinking inertia, and has a low transformation cost for sewing equipment and is applicable to the transformation of a single sewing station (in the station, a single sewing needle corresponds to multiple rope ends), with high practical popularization and application value.

[0007] Preferably, the multi-rope-end jabbing auxiliary device further includes a material pushing mechanism, which includes a first driving component and a pushing plate. The sewing channel has a feeding side close to the feeding direction. The pushing plate is arranged on the side of the sewing channel away from the feeding side and faces the sewing channel. The first driving component is in transmission connection with the pushing plate, and the first driving component can drive the pushing plate to perform a pushing action and a reset action along the sewing channel.

[0008] This preferred solution can push the sewn rope ends out of the sewing channel after a single sewing operation, facilitating the feeding of the next sewing operation and further improving the mechanization degree of the jabbing process. Specifically, the first driving component is a known driving component capable of linear motion.

[0009] Preferably, the first driving component is a double-acting cylinder, the pushing plate is connected to the piston rod of the double-acting cylinder, and the multi-rope-end jabbing auxiliary device is provided with a photoelectric inductor for detecting feeding.

[0010] The double-acting cylinder belongs to a linear motion mechanism using a linear guiding shaft and a linear bearing block unit. By using a shaft with an embedded part, it is relatively easy to ensure the accuracy (parallelism) during assembly, which helps to synchronously push out all the sewn rope ends in this preferred solution. In a normal working process, after detecting the feeding, the sewing machine starts the current sewing operation. After the sewing operation is completed, the material pushing mechanism performs a pushing action and a reset action to empty the sewing channel.

[0011] The present utility model also provides a sewing machine, which includes the multi-rope-end jabbing auxiliary device in any one of the foregoing solutions. A plurality of pressing parts are provided on the lower side of the presser foot of the sewing machine, and a spacer gap is provided between adjacent two pressing parts. The plurality of pressing parts are arranged in one-to-one correspondence with the plurality of sewing channels, and the spacer is arranged in the corresponding spacer gap. The multi-rope-end jabbing auxiliary device is installed on the synchronous feeding plate of the sewing machine, or the multi-rope-end jabbing auxiliary device is used to replace the synchronous feeding plate of the sewing machine.

[0012] The synchronous feeding plate, also known as the feed plate, etc., can realize the function of synchronously feeding the fabric during the sewing process, which belongs to the prior art. In this solution, the multi-rope-end jabbing auxiliary device is usually installed on the synchronous feeding plate, or the multi-rope-end jabbing auxiliary device is added with a structure that can realize the function of synchronously feeding the fabric during the sewing process and is the same as the existing synchronous feeding plate to replace the synchronous feeding plate of the sewing machine.

[0013] Preferably, the sewing machine includes an automatic folding and feeding device, which includes a clamping member, a folding mechanism and a feeding transfer mechanism. The folding mechanism is provided with a folding motor, and a clamping member mounting seat for mounting the clamping member is arranged on the rotating shaft of the folding motor. The clamping member is provided with a clamping part for clamping the rope end, and the clamping part is arranged in a position matching the sewing channel. The folding mechanism is installed on the feeding transfer mechanism, and the feeding transfer mechanism can transfer the clamping part to the sewing channel.

[0014] Through the cooperation of the automatic folding and sewing device and the multi - rope head button sewing auxiliary device, the mechanization degree of the button sewing process is further improved, liberating manpower and reducing working errors.

[0015] Preferably, the side - positioned part and the partition part are both parallel to the feeding direction. The number of partition parts is one. The sewing area is separated by the partition part to form two sewing channels. The presser foot has two pressing parts, and a partition part gap is reserved between the two pressing parts. This preferred solution forms a multi - rope head button sewing auxiliary device. For example only, the number of partition parts is one or two or three. When the number of partition parts is one, the sewing space is separated to form two sewing channels; when the number of partition parts is two, the sewing space is separated to form three sewing channels, and so on.

[0016] Preferably, the multi - rope head button sewing auxiliary device is provided with a limiting elastic piece along the feeding direction, and the limiting elastic piece is used for longitudinally limiting the clamping piece.

[0017] In the solution, the limiting elastic piece longitudinally limits the clamping piece, which is beneficial for the clamping piece to accurately transfer the rope head into the sewing channel. And using the elastic piece material is beneficial for reducing the rigid damage caused by the high - frequency transfer of the clamping piece. The elastic piece material is preferably made of stainless steel with elastic memory function such as spring steel.

[0018] Further preferably, the side - positioned part and the partition part are both parallel to the feeding direction. The sewing channel has a first opening exposed in the feeding direction. The height of the partition part is lower than that of the side - positioned part. The limiting elastic pieces are arranged at intervals on the upper side of the side - positioned part. A receiving space for limiting the clamping piece is reserved between the limiting elastic piece and the side - positioned part. The receiving space has a second opening exposed in the feeding direction. The end of the limiting elastic piece close to the feeding direction is the feeding end, and the limiting elastic piece is provided with an upward bending part at the feeding end.

[0019] This solution not only realizes the longitudinal limitation of the clamping piece by the limiting elastic piece, but also the further - set upward bending part is beneficial for the clamping piece to smoothly transition into the receiving space, which is beneficial for the clamping piece to accurately transfer the rope head into the sewing channel. The opening of the receiving space along the feeding direction is beneficial for reducing the lateral obstacle when the clamping piece feeds along the feeding direction.

[0020] Further preferably, the feeding and transferring mechanism includes an X - direction transferring mechanism and a Y - direction transferring mechanism. The X - direction transferring mechanism has a sliding seat and a second driving component. The second driving component can drive the sliding seat to move along the X - direction. The Y - direction transferring mechanism is arranged on the sliding seat. The Y - direction transferring mechanism includes a folding mechanism mounting seat and a third driving component. The third driving component can drive the folding mechanism mounting seat to move along the Y - direction. The folding mechanism is installed on the folding mechanism mounting seat. The Y - direction is parallel to the feeding direction, and the X - direction is perpendicular to the feeding direction. Exemplarily, the driving component is a combination of a cylinder or a driving motor and a well - known transmission component, which will not be elaborated here.

[0021] Beneficial effects: Compared with the prior art, by combining the functions of the multi-rope-end button sewing auxiliary device and the synchronous feeding plate in the present invention, in a normal working process, multiple folded rope ends are fed, placed in multiple sewing channels respectively - the presser foot presses the rope ends in all sewing channels - the sewing work on the rope ends in the working channel is completed - the next sewing channel is switched to the working channel to continue sewing - the current sewing work is completed, and the sewn rope ends are obtained. In this solution, not only multi-rope-end button sewing is realized, but also it is beneficial to avoid sewing adhesion of multiple rope ends during single sewing, and high-quality and efficient button sewing work on multiple rope ends is realized during single sewing, with a high degree of mechanization.
