Description

Technical Field

[0001] The utility model relates to the technical field of bag opening machines, in particular to a laser bag opening, folding and sewing integrated machine. Background Art

[0002] Taking the processing of clothing bag openings as an example, it is necessary to first open the bag opening and then sew the corresponding fabric accessories. At present, automatic bag opening machines are used for processing in the industry. The folding mechanism commonly configured on automatic bag opening machines is arranged above the workbench, which requires a large amount of space above the workbench.

[0003] For example, CN 114855373 A discloses a bag opening machine for clothing bag openings, including a frame with a workbench, a support frame, a sewing machine, a laser cutting mechanism, a folding mechanism, a clamping mechanism, a shaping mechanism, and a sliding mechanism. The sliding mechanism is arranged below the workbench; the laser cutting mechanism and the folding mechanism are sequentially arranged on the support frame; the workbench is provided with a strip-shaped through hole along the direction of the laser cutting mechanism and the folding mechanism as a sliding channel. The shaping mechanism and the clamping mechanism are symmetrically arranged above the workbench. The vertical plate passes through the sliding channel, and the upper and lower ends of the vertical plate are respectively connected to the overall connection formed by the sliding mechanism, the shaping mechanism, and the clamping mechanism. The overall connection formed by the shaping mechanism and the clamping mechanism can be respectively moved to the laser cutting mechanism, the sewing machine, or the folding mechanism through the sliding mechanism; the laser cutting mechanism is used to cut the fabric into pocket pieces, the folding mechanism folds the pocket pieces, the clamping mechanism is used to clamp and fix the clothing fabric to be processed, and the shaping mechanism presses and shapes the clothing fabric and the bag lip and moves it to the lower part of the sewing machine for stitching.

[0004] For this kind of bag opening machine for clothing bag openings, the sewing machine is fixed on the front right side of the workbench, and it is mainly applicable to products that can only be sewn and processed once. If different accessories need to be sewn twice on the product, after sewing once, the clamping mechanism and the shaping mechanism return to the loading position, then accessories are loaded on the clamping mechanism and the shaping mechanism, and then transferred to the lower part of the sewing machine for stitching. Its operation is relatively troublesome, loading accessories takes time, and the production efficiency is low. Moreover, this kind of bag opening machine with an upper folding mechanism occupies a large amount of space above the workbench, and it is not convenient to press and shape the folded edge part of the bag opening, making it difficult to meet the requirements of manufacturers with higher sewing quality and production efficiency.

Further, corresponding to the first sewing station C and the second sewing station D on the workbench surface 10, two stop portions 3 with a left-right spacing are provided at the rear side. The stop portions 3 are controlled to lift by corresponding lifting cylinders 4. The lifting cylinders 4 are arranged below the workbench surface 10. The upper stop portions protrude above the workbench surface 10. The operator can place the fabric between the two stop portions 3 corresponding to the first sewing station C and the second sewing station D respectively, which is convenient for quickly aligning and placing the fabric. An avoidance hole 5 is provided on the workbench surface 10 for the corresponding stop portion 3 to protrude. Usually, the avoidance hole 5 is designed as a long strip extending left and right, so that the left and right positions of the stop portion 3 can be adjusted, thereby meeting the alignment placement of fabrics of a certain size. For example: The telescopic rod of the lifting cylinder 4 extends upward and is drivingly connected to a base 6. A translation adjustment cylinder 7 is provided on the base 6. The telescopic rod of the translation adjustment cylinder 7 extends in the left-right direction and is drivingly connected to the stop portion 3. In this way, the relative position of the stop portion 3 in the left-right direction is automatically adjusted by using the translation adjustment cylinder 7, and the lifting cylinder 4 controls the lifting height of the stop portion 3.

[0047] The working process of the bag opening machine in this embodiment is introduced as follows:

[0048] Step 1: Load the fabric to be bagged on the transfer device 200.

[0049] Step 2: When the transfer device 200 is located at the laser bag opening station B, the laser cutting device 500 cuts a cut, and the cut is generally as Figure 10 shown: A straight seam is connected between two opposite V-shaped seams.

[0050] Step 3: The transfer device 200 transfers to the hemming and pressing station A. The pushing part 24 extends into the first through groove 11 to fold the four side edges a of the cut downward. The first hemming mechanism 30 and the second hemming mechanism 30 fold the four side edges a outward along the bottom of the workbench surface 10. The pressing part 23 abuts against the annular area b outside the corresponding four side edges a at the top of the fabric to press and shape the bag mouth hemming part. Usually, the hemming and pressing can be maintained for a certain period according to the setting.

[0051] Step 4: The pressing mechanism 20 resets (upward), and the hemming mechanism 30 resets (for example: the left hemming knife 31, the right hemming knife 32, the front hemming knife 34, and the rear hemming knife 35 reset inward, and the first hemming mechanism 30 and the second hemming mechanism 30 reset downward).

[0052] Step 5: The transfer device 200 moves upward and then translates rightward to the first sewing station C (before the transfer device 200 reaches the first sewing station C, the first fitting has been placed at the first sewing station C); the upper sewing head device 301 and the lower rotary hook device 302 translate leftward to the first sewing station C (or the upper sewing head device 301 and the lower rotary hook device 302 have already been waiting at the first sewing station C).

[0053] Step 6: The transfer device 200 moves downward, the tray 201 presses on the first fitting, and the sewing device 300 performs the first sewing process to sew and connect the fabric and the first fitting.

[0054] Step 7: The transfer device 200 moves upward and then translates rightward to the second sewing station D (before the transfer device 200 reaches the second sewing station D, the second fitting has been placed at the second sewing station D); the upper sewing head device 301 and the lower rotary hook device 302 translate rightward to the second sewing station D (or the upper sewing head device 301 and the lower rotary hook device 302 are waiting at the second sewing station D in advance).

[0055] Step 8: The transfer device 200 moves downward, the tray 201 presses on the second fitting, and the sewing device 300 performs the second sewing process to sew and connect the second fitting and the fabric.

[0056] For the case where more sewing processes are still required, a third accessory can be continuously placed at the first sewing station C. The transfer device 200 moves upward and then translates leftward to the first sewing station C. The upper sewing head device 301 and the lower rotating shuttle device 302 translate leftward to the first sewing station C. The transfer device 200 moves downward, and the tray 201 presses on the third accessory. The sewing device 300 performs the third sewing process to sew and connect the third accessory and the fabric. Even further, a fourth accessory can be placed at the second sewing station D... In this way, by repeatedly using the first sewing station C and the second sewing station D, the sewing device 300 reciprocates left and right and translates to perform sewing operations at the first sewing station C and the second sewing station D respectively.

[0057] From Figure 1 It can be seen that the arrangements of the hemming and pressing station A, the laser bag-opening station B, the first sewing station C, and the second sewing station D are relatively compact. In particular, the hemming and pressing station A and the laser bag-opening station B are adjacent to each other. Since the laser bag-opening station B serves as the loading and unloading station and the hemming mechanism 30 is arranged below the workbench surface 10, the space of the hemming and pressing station A can be utilized. Combining steps 1, 2, and 3, in this embodiment, when the fabric to be bag-opened is loaded at the laser bag-opening station B and laser cutting is performed, the laser cutting device 500 does not translate. By virtue of the left and right translation and the front and back translation of the transfer device 200, the laser cutting device 500 cuts a notch in the fabric. When performing the left and right translation action, the transfer device 200 translates leftward to the hemming and pressing station A. That is to say, while the laser cutting process is being carried out, the transfer device 200 gradually translates leftward to the hemming and pressing station A. On the one hand, it cleverly utilizes the adjacent space of the laser bag-opening station B and the hemming and pressing station A as the space required for the translation action of the transfer device 200 during laser cutting. On the other hand, it saves the time required for special translation to the hemming and pressing station A after laser cutting. For the bag-opening machine of this embodiment, by arranging the hemming and pressing station A, the laser bag-opening station B, the first sewing station C, and the second sewing station D from left to right on the workbench surface 10, and by arranging a specially structured bag mouth hemming device 100, a laser cutting device 500, a transfer device 200, and a sewing device 300 on the machine frame, the integrated operation efficiency of bag-opening, hemming, and sewing is effectively improved. Moreover, the overall front-to-back width of the bag-opening machine becomes smaller. In actual use, two bag-opening machines can be placed back-to-back adjacent to each other. In this way, the space occupied by a traditional bag-opening machine can be used to place two bag-opening machines after innovative design, which is beneficial for workshop storage management and convenient for staff to control the bag-opening machine.

[0058] When the bag opening machine is actually used, according to the processing requirements of different products, it may only need to perform sewing processing once, that is, only one sewing station is required. Therefore, the innovatively designed bag opening machine can meet the sewing processing requirements of bag opening products for single or multiple sewing processes.

[0059] The key point of the design of the present utility model is that mainly a workbench surface is arranged on the frame, and a hemming and pressing station, a laser bag opening station, a first sewing station and a second sewing station are sequentially arranged on the workbench surface from left to right. Combined with the settings of the bag mouth hemming device, the laser cutting device, the transfer device and the sewing device, in particular, the sewing device can move left and right back and forth between the first sewing station and the second sewing station to perform sewing processing at the first sewing station and the second sewing station respectively. In this way, the accessories can be placed at the first sewing station and the second sewing station respectively, meeting the requirements of multiple accessory sewing processing, with simple operation, avoiding occupying sewing time due to placing accessories, and effectively improving the production and processing efficiency. Secondly, the pressing and ironing mechanism 20 is cleverly arranged above the workbench surface 10, and the hemming mechanism 30 is arranged below the workbench surface 10, realizing hemming operation below the workbench surface 10, effectively saving the space above the workbench surface 10, making the equipment structure more compact, and being able to press and shape the bag mouth hemming part during hemming, so that the hemming retention effect is good, the creases are obvious and regular, which is beneficial to improving the quality of subsequent sewing processing.

[0060] The above description is only a preferred embodiment of the present utility model, and does not impose any limitation on the technical scope of the present utility model. Therefore, any minor modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still belong to the scope of the technical solution of the present utility model.
