Description

Technical Field

[0001] The present invention relates to the technical field of glove auxiliary equipment, and in particular to an automatic glove turning machine. Background Art

[0002] Mittens are gloves with separate thumbs and four fingers connected together, usually made of knitted or woven fabrics. The production process of mittens must use sewing technology to sew the joints together. During the production process, the gloves are sewn from the reverse side. After sewing, they are turned over so that the flat side is the front side and the seams are hidden inside, which not only avoids the wear of the sewing thread ends, but also improves the appearance of the gloves.

[0003] In the existing technology, the work of turning gloves during the production process still relies on manpower. Workers use some simple glove turning tools to turn the reverse side of the gloves to the inside, which is not only time-consuming and laborious, but also such repetitive work for a long time will cause calluses and soreness on the workers' palms, resulting in reduced production efficiency. Summary of the invention

[0004] In view of the shortcomings of the prior art, the object of the present invention is to provide an automatic glove turning machine, which can quickly turn gloves, save time and labor, and improve production efficiency.

[0005] The above-mentioned object of the present invention is achieved through the following technical solutions:

[0006] An automatic glove turning machine comprises a base, a glove positioning plate and two mutually parallel sliding rods are fixedly connected to the base, the glove positioning plate is arranged between the two sliding rods, an upper push plate and a lower pressure plate are slidably connected to the two sliding rods, a through hole for the glove positioning plate to pass through is opened on the upper push plate, a first cylinder is arranged in the base, and a piston rod of the first cylinder is drivingly connected to the upper push plate;

[0007] One end of the two sliding rods away from the base is detachably fixedly connected to a fixing plate, and a second cylinder is arranged on the fixing plate, and the lower pressing plate is arranged between the fixing plate and the upper pushing plate and is drivingly connected to the piston rod of the second cylinder;

[0008] A palm push rod is fixedly connected to a side of the lower pressure plate away from the fixed plate, a third cylinder is fixed to the lower pressure plate, a piston rod of the third cylinder passes through the lower pressure plate and is fixedly connected to a thumb push rod, and the thumb push rod and the palm push rod are respectively contactable and separable from one end of the glove positioning plate.

[0009] Through the above technical solution, before turning over the glove, put the glove on the glove positioning plate and press the start button, the second cylinder drives the lower pressing plate to move downward, and the third cylinder on the lower pressing plate also moves downward. When the palm push rod and the thumb push rod press the upper end of the glove on the glove positioning plate, the second cylinder and the third cylinder are in place and no longer move. After that, the first cylinder drives the upper push plate to move upward, and the upper push plate drives the glove to move upward. Since the palm push rod and the thumb push rod press the upper end of the glove, the fabric under the glove turns over along the glove positioning plate in the direction of the palm push rod and the thumb push rod. When the upper push plate pushes the thumb of the glove just to turn out, the first cylinder and the third cylinder move upward synchronously at the same time. When the upper push plate turns the glove fabric onto the palm push rod and the thumb push rod, the second cylinder drives the lower pressing plate and the third cylinder on the lower pressing plate to move upward synchronously with the first cylinder. When the second cylinder and the third cylinder move upward to the right position, the first cylinder continues to move upward until the glove is completely turned out. The first cylinder stops moving and moves downward to reset after a delay (the time for manual removal of the glove). The glove is removed from the palm push rod and the thumb push rod to preliminarily complete the glove turning work. The entire glove turning process utilizes the mutual cooperation between multiple cylinders and the palm push rod, the thumb push rod and the glove positioning plate, making the shaping glove work faster and easier, saving time and effort, and greatly improving production efficiency.

[0010] In a preferred example, the present invention can be further configured as follows: the glove positioning plate includes a palm cover plate and a thumb cover rod, the palm cover plate is arranged higher than the thumb cover rod, and an arc-shaped rounded corner is formed on the palm cover plate.

[0011] Through the above technical solution, the palm sleeve plate and the thumb sleeve rod cooperate with the palm push rod and the thumb push rod to perform the glove turning process, and on the other hand, they match the shape of the mittens, making it easy to fix the mittens on the glove positioning plate. The arc-shaped rounded corners on the palm sleeve plate not only effectively protect the gloves and make them not easy to be damaged, but also the humanized design makes it difficult for workers to scratch their hands when installing gloves on the glove positioning plate, thereby improving production safety.

[0012] In a preferred example, the present invention can be further configured as follows: an end of the palm push rod away from the lower pressure plate is fixedly connected to an abutment block, and the abutment block is arranged in an arc shape on one side close to the palm cover plate.

[0013] Through the above technical solution, the setting of the abutment block increases the area where the top of the mitten is fixed on the palm cover plate, so that the mitten is evenly stressed during the turning process, thereby ensuring the quality of the mitten. At the same time, the abutment block with an arc shape on one side enables it to better match the palm end of the mitten, avoiding damage to the mitten during shaping, thereby improving the quality of the product.

[0014] In a preferred example, the present invention can be further configured as follows: an insertion groove for inserting the thumb push rod is formed at one end of the thumb sleeve rod away from the base.

[0015] Through the above technical solution, the mittens are sleeved on the glove positioning plate, and when the lower pressure plate moves downward, the thumb push rod is inserted into the insertion groove on the thumb sleeve rod, so that the thumb part of the mittens can be completely turned out, thereby improving the plastic effect of the mittens.

[0016] In a preferred example, the present invention can be further configured as follows: two linear bearings are installed on a side of the upper push plate close to the base, and the linear bearings are slidably matched with the slide rod.

[0017] Through the above technical solution, on the linear bearing, since the load-bearing ball is in point contact with the bearing outer sleeve, the steel ball rolls with minimal friction resistance. Therefore, the linear bearing has low friction and is relatively stable. It does not change with the bearing speed, and can enable the push plate to obtain smooth linear motion with high sensitivity and high precision.

[0018] In a preferred example, the present invention can be further configured as follows: a cylinder floating joint is installed on the piston rod of the second cylinder, and one end of the cylinder floating joint away from the second cylinder is detachably fixedly connected to the lower pressure plate.

[0019] Through the above technical solution, the cylinder floating joint is a part connecting the cylinder and the drive, in which the drive part is the lower pressure plate, which can absorb the "eccentric" lack of parallelism (angle) between the drive body and the cylinder, and the thrust will not be reduced even if the coaxiality is low. At the same time, it prevents the cylinder seal ring from being damaged, prolongs the life of the cylinder, and facilitates the replacement of different types of cylinders according to actual needs.

[0020] In a preferred example, the present invention can be further configured as follows: a shaping plate is fixedly connected to the upper edge of the base.

[0021] Through the above technical solution, workers can put the gloves on the shaping plate after taking them off from the automatic glove turning machine, and then take them off after shaping, thereby improving the shaping effect of the gloves.

[0022] In summary, the present invention includes at least one of the following beneficial technical effects:

[0023] 1. The entire glove turning process utilizes the cooperation between multiple cylinders and the palm push rod, thumb push rod and glove positioning plate, making the glove shaping work faster and easier, saving time and effort, and greatly improving production efficiency.

[0024] 2. The palm sleeve plate and thumb sleeve rod cooperate with the palm push rod and thumb push rod to turn the gloves, and match the shape of the mittens to facilitate fixing the mittens on the glove positioning plate. The arc-shaped rounded corners on the palm sleeve plate not only effectively protect the gloves and make them less likely to be damaged, but also the humanized design makes it less likely for workers to scratch their hands when installing gloves on the glove positioning plate, thereby improving production safety.

[0025] 3. The mittens are sleeved on the glove positioning plate, and when the lower pressing plate moves downward, the thumb push rod is inserted into the insertion groove on the thumb sleeve rod, so that the thumb part of the mittens can be completely turned out, thereby improving the plastic effect of the mittens.

DETAILED DESCRIPTION

[0029] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0030] Reference Figure 1 , an automatic glove turning machine disclosed in the present invention comprises a base 1, a glove positioning plate 2 and two mutually parallel slide bars 3 are fixedly connected to the base 1, the glove positioning plate 2 is arranged between the two slide bars 3, an upper push plate 31 and a lower pressure plate 32 are slidably connected to the two slide bars 3, a through hole for the glove positioning plate 2 to pass through is opened on the upper push plate 31, a first cylinder 11 is arranged in the base 1, and a piston rod of the first cylinder 11 is drivingly connected to the upper push plate 31.

[0031] The ends of the two slide bars 3 away from the base 1 are detachably fixedly connected to a fixing plate 33, a second cylinder 331 is arranged on the fixing plate 33, and the lower pressing plate 32 is arranged between the fixing plate 33 and the upper pushing plate 31 and is in driving connection with the piston rod of the second cylinder 331. A palm push rod 321 is fixedly connected to the side of the lower pressing plate 32 away from the fixing plate 33, a third cylinder 322 is fixed on the lower pressing plate 32, and the piston rod of the third cylinder 322 passes through the lower pressing plate 32 and is fixedly connected to a thumb push rod 323, and the thumb push rod 323 and the palm push rod 321 are respectively contactable and separable with one end of the glove positioning plate 2.

[0032] Reference Figure 1 The glove positioning plate 2 includes a palm sleeve plate 21 and a thumb sleeve rod 22. The palm sleeve plate 21 is arranged higher than the thumb sleeve rod 22, and an arc-shaped fillet is provided on the palm sleeve plate 21. The palm sleeve plate 21 and the thumb sleeve rod 22 cooperate with the palm push rod 321 and the thumb push rod 323 to perform the glove turning process, and conform to the shape of the mittens, so as to facilitate the fixing of the mittens on the glove positioning plate 2. The arc-shaped fillet provided on the palm sleeve plate 21 not only effectively protects the gloves and makes them not easy to be damaged, but also the humanized design makes it difficult for workers to scratch their hands when installing gloves on the glove positioning plate 2, thereby improving the safety of production.

[0033] Among them, the end of the thumb sleeve rod 22 away from the base 1 is provided with an insertion slot 221 for inserting the thumb push rod 323, and the mitten is sleeved on the glove positioning plate 2. When the lower pressing plate 32 moves downward, the thumb push rod 323 is inserted into the insertion slot 221 on the thumb sleeve rod 22, so that the thumb part of the mitten can be completely turned out, thereby improving the shaping effect of the mitten. Furthermore, a shaping plate 12 is fixedly connected to the upper edge of the base 1. After the worker takes off the gloves from the automatic glove turning machine, he can sleeve them on the shaping plate 12, shape the gloves and then take them off, thereby improving the shaping effect of the gloves.

[0034] Reference Figure 2 The end of the palm push rod 321 away from the lower pressing plate 32 is fixedly connected with an abutment block 4, and the abutment block 4 is arranged in an arc shape on the side close to the palm cover plate 21. The arrangement of the abutment block 4 increases the area where the top of the mitten is fixed on the palm cover plate 21, so that the mitten is evenly stressed during the process of turning the gloves, thereby ensuring the quality of the mitten. At the same time, the abutment block 4 arranged in an arc shape enables it to better match the palm end of the mitten, thereby avoiding damage to the mitten during shaping, thereby improving the quality of the product.

[0035] Two linear bearings 5 ​​are installed on one side of the upper push plate 31 close to the base 1, and the linear bearings 5 ​​are slidably matched with the slide rod 3. On the linear bearings 5, since the load-bearing balls are in point contact with the bearing outer sleeve, the steel balls roll with minimal friction resistance, so the linear bearings 5 ​​have low friction and are relatively stable, and do not change with the bearing speed, so that the upper push plate 31 can obtain a stable linear motion with high sensitivity and high precision.

[0036] Reference Figure 2, a cylinder floating joint 6 is installed on the piston rod of the second cylinder 331, and one end of the cylinder floating joint 6 away from the second cylinder 331 is detachably fixedly connected to the lower pressure plate 32. The cylinder floating joint 6 is a part connecting the cylinder and the drive, and the drive part is the lower pressure plate 32. It can absorb the "eccentric" parallelism (angle) between the drive body and the cylinder, and the thrust will not be reduced even if the coaxiality is low. At the same time, it prevents the cylinder sealing ring from being damaged, prolongs the life of the cylinder, and is convenient for replacing cylinders of different models according to actual needs.

[0037] In this embodiment, the model of the first cylinder 11 is SC50-800S cylinder, the model of the second cylinder 331 is SCJ50-100-50S cylinder, and the model of the third cylinder 322 is SCJ50-150-50S cylinder. The model of the linear bearing 5 is LM40UU linear bearing, and the number of linear bearings 5 ​​is four, two of which are arranged on the lower pressure plate 32, and the other two are arranged on the upper push plate 31. The model of the cylinder floating joint 6 is FD-M16*1.5 cylinder floating joint, and the number of cylinder joints is set to two, one of which is fixed between the second cylinder 331 and the lower pressure plate 32, and the other is fixed between the first cylinder 11 and the upper push plate 31.

[0038] The working principle of this embodiment is as follows: before turning over the glove, put the glove on the glove positioning plate 2 and press the start button, the second cylinder 331 drives the lower pressing plate 32 to move downward, and the third cylinder 322 on the lower pressing plate 32 also moves downward. When the palm push rod 321 and the thumb push rod 323 press the upper end of the glove on the glove positioning plate 2, the second cylinder 331 and the third cylinder 322 are in place and no longer move.

[0039] In this embodiment, a magnetic sensor is provided on the first cylinder 11, and solenoid valves are provided on the second cylinder 331 and the third cylinder 322, respectively, and the magnetic sensor is connected to the solenoid valve. When the third cylinder 322 is pressed down to the right position, the magnetic sensor on the third cylinder 322 receives a signal to supply power to the solenoid valve of the first cylinder 11, and then the first cylinder 11 drives the upper push plate 31 to move upward, and the upper push plate 31 drives the glove to move upward. Since the palm push rod 321 and the thumb push rod 323 press the upper end of the glove, the cloth under the glove turns up along the glove positioning plate 2 toward the direction of the palm push rod 321 and the thumb push rod 323.

[0040] When the upper push plate 31 pushes the thumb of the glove just to turn out, the magnetic sensor at the lower end of the first cylinder 11 receives a signal to power the solenoid valve of the third cylinder 322, and the first cylinder 11 and the third cylinder 322 move upward synchronously at the same time. When the upper push plate 31 turns the entire glove fabric onto the palm push rod 321 and the thumb push rod 323, the magnetic sensor in the middle of the first cylinder 11 receives a signal to power the solenoid valve of the second cylinder 331. At this time, the second cylinder 331 drives the lower pressing plate 32 and the third cylinder 322 on the lower pressing plate 32 to move upward synchronously with the first cylinder 11.

[0041] When the second cylinder 331 and the third cylinder 322 move upward to their positions, the first cylinder 11 continues to move upward until the gloves are completely turned out, and the magnetic sensor on the upper part of the first cylinder 11 receives a signal to power the delay relay, so that the first cylinder 11 stops moving and delays (the time for manually removing the gloves) to move downward to reset, and the gloves are removed from the palm push rod 321 and the thumb push rod 323, and the glove turning work is preliminarily completed. The entire glove turning process utilizes the mutual cooperation between multiple cylinders and the palm push rod 321, the thumb push rod 323 and the glove positioning plate 2, making the shaping glove work faster and easier, saving time and effort, and greatly improving production efficiency.

[0042] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
