Description

TECHNICAL FIELD

[0001] The present application belongs to the field of shoe preparation, and particularly relates to a device and method for precise matching of shoe soles and uppers. BACKGROUND

[0002] A traditional shoe production line has a process called matching of shoe soles and uppers, which is mainly to ensure that the shoe soles and uppers are matched when the shoe soles are manually attached, and the implementation mainly consists of two ways:

[0003] 1. For large orders, the style of the shoes to be produced needs to be arranged in advance, and the production is carried out according to the placement of the shoes; ① When the shoe soles are manually placed, the shoe soles and uppers are matched by observing the number of uppers and the information of left and right feet; ② The traditional placement method depends entirely on the judgment of the workers, so the production process may cause the matching of the shoe soles and uppers to fail, which greatly affects the production efficiency of the production line

[0004] 2. In view of the problems existing in the traditional shoe matching, the shoe production line in the forming middle stage of the shoe production line in the matching process has a bottom matching workbench, the bottom matching workbench has a display screen, the shoe last with the upper has an RFID card, each RFID card has the style information of the upper (including left and right feet and size), the reader device reads the upper information when passing through the bottom matching workbench, the display screen of the bottom matching workbench displays the information of the shoe soles to be matched, and the workers place the corresponding shoe soles according to the matching information to ensure the matching of the shoe soles and uppers.

[0005] However, the matching of the intelligent line has the following problems: (1) Although the shoe soles and uppers can be matched when the shoe soles are placed, the glue spraying of the entire shoe soles and uppers must be stably produced during the production process, but in the actual production process, the shoe soles or uppers may have problems such as glue blocking and glue overflow, which may cause the shoe soles or uppers to be short of glue or overflow, and at this time, the workers need to intervene to handle the problems, and there are two methods: first, the workers take out the problematic uppers or shoe soles to handle them, and then put them back into the production line, which may cause the original matched uppers or shoe soles to be mixed, and the matching of the shoe soles and uppers cannot be achieved when the shoe soles are attached; second, the workers want to take out the problematic shoe soles or uppers at the same time, but it is difficult to know which shoe soles are matched with the uppers, because there is no correlation between them, which may cause the shoe soles and uppers to be unable to be matched.

[0025] The upper conveying mechanism conveys the upper to the upper information reader, acquires the code information and left-right foot information of the upper through the upper RFID card, feeds back the acquired information to the control mechanism, and then places the corresponding sole in the corresponding tray according to the information displayed by the control mechanism, and records the code information and left-right foot information of the sole in the sole RFID card through the code recorder, at this time, the relationship between the sole and the tray and the relationship between the sole and the upper are established one by one, and the initial matching of the sole with the upper is completed.

[0026] Precise matching of soles with uppers

[0027] The shoe upper conveying belt and the shoe sole conveying belt respectively send the shoe upper and the shoe sole into the glue spraying mechanism for glue spraying treatment. The shoe sole after the glue spraying treatment is firstly acquired by the shoe sole information acquisition device for code number information and left-right foot information, and then enters the buffer position, so that the plurality of buffer positions and the shoe sole information form a one-to-one correspondence relationship. Before the shoe upper after the glue spraying enters the activation mechanism for activation, the shoe upper is acquired by the shoe upper code reading mechanism for code number information and left-right foot information, and waits at the activation mechanism entrance for matching with the shoe sole to enter the activation mechanism. After the shoe upper information acquired by the shoe upper code reading mechanism is matched with the shoe sole on the buffer mechanism, the moving part cooperates with the buffer table to automatically call the shoe sole of the corresponding buffer position, and the matched shoe sole is sent into the activation mechanism by the pushing part together with the shoe upper to enter the activation mechanism for activation, so as to realize accurate matching of the shoe sole and the shoe upper.

[0028] Further, in the process of accurate matching of the shoe sole and the shoe upper, when the shoe sole or the shoe upper has overflow glue, glue blockage and the like, manual intervention is required. At this time, the shoe sole and the corresponding tray or the shoe upper with problems are taken out by hand for processing. When the problem is the shoe sole, the shoe upper after the glue spraying is matched with the corresponding shoe sole by the buffer mechanism. If the shoe sole is missing, the control mechanism prompts that the corresponding shoe sole needs to be supplemented or the opposite shoe upper is removed from the shoe upper conveying belt. When the problem is the shoe upper, the shoe sole is directly continued to be stored in the buffer position, which does not affect the automatic matching of the shoe sole and the shoe upper. After the shoe upper is processed, the shoe upper is re-placed on the shoe upper conveying belt, and the corresponding shoe sole is re-called for matching.

[0029] Further, in the process of accurate matching of the shoe sole and the shoe upper, when the shoe sole or the shoe upper has overflow glue, glue blockage and the like, manual intervention is required. At this time, the shoe sole and the corresponding tray or the shoe upper with problems are taken out by hand for processing. When the problem is the shoe sole, the shoe upper after the glue spraying is matched with the corresponding shoe sole by the buffer mechanism. If the shoe sole is missing, the control mechanism prompts that the corresponding shoe sole needs to be supplemented or the opposite shoe upper is removed from the shoe upper conveying belt.

After the shoe upper is processed, the shoe upper is re-placed on the shoe upper conveying belt, and the corresponding shoe sole is re-called for matching.

[0030] From the above description of the present application, compared with the prior art, the beneficial effects of the present application are: the present application specifically limits the structure of the shoe sole and shoe upper matching device, adds the buffer mechanism, and matches again before the shoe sole and shoe upper enter the activation, and further limits the structure of the buffer mechanism to cooperate with other mechanisms to solve the problem of matching of the shoe sole and shoe upper in the existing intelligent line / traditional line; it can also solve the problem that the shoe sole / shoe upper cannot be taken and placed at the same time due to overflow glue, insufficient glue and glue blockage and the like; it can also solve the problem of error in bottom pasting caused by confusion in matching of the shoe sole and shoe upper, reduce the scrap rate of shoes, and realize efficient production of the production line.

[0039] The sole conveying mechanism 1 is used for conveying soles along the production line direction, comprising a sole conveying belt 11, a tray 12 for placing soles arranged on the sole conveying belt 11, and a sole RFID card 13 arranged in the tray 12.

[0040] The vamp conveying mechanism 2 is used for conveying the vamp along the production line direction, and comprises a vamp conveying belt 21 arranged below the sole conveying belt 11, a placing table 22 arranged on the vamp conveying belt 21 and used for placing the vamp, and a vamp RFID card 23 arranged in the placing table 22.

[0041] The information acquisition and initial matching mechanism 3 comprises a vamp information acquirer 31 used for reading the information of the vamp RFID card 23 and feeding back to the control mechanism 0, and a code writer 32 used for recording the sole information in the sole RFID card 13. During the initial matching, the corresponding sole is placed on the tray 12 according to the vamp information obtained by the vamp information acquirer 31, and the obtained information is fed back to the control mechanism 0. The control mechanism 0 records the received information in the sole RFID card 13 through the code writer 32. Specifically, the vamp information acquirer 31 comprises a second support 311 arranged at the side of the vamp conveying belt 21, and a vamp RFID reader-writer 312 arranged on the second support 311 and used for reading the information of the vamp RFID card 23.

[0042] The spraying mechanism 4 sprays the treatment agent on the soles and the vamp on the sole conveying belt 11 and the vamp conveying belt 21, respectively. Specifically, the spraying mechanism 4 is a treatment agent spraying device commonly used in the shoe preparation field, and the specific structure and working principle thereof will be further described.

[0043] The glue spraying mechanism 5 is arranged behind the spraying mechanism 4, and sprays the glue on the soles and the vamp on the sole conveying belt and the vamp conveying belt 21, respectively. Specifically, the glue spraying mechanism 5 is a glue spraying device commonly used in the shoe preparation field, and the specific structure and working principle thereof will be further described.

[0044] The activation mechanism 7 comprises a first activation mechanism 71 and a second activation mechanism 72. The first activation mechanism 71 is arranged between the spraying mechanism 4 and the glue spraying mechanism 5, and is used for activating the treatment agent on the entering soles and vamp. The second activation mechanism 72 is arranged behind the glue spraying mechanism 5, and is used for activating the glue on the entering soles and vamp. Specifically, the first activation mechanism 71 and the second activation mechanism 72 are both ovens.

[0045] The buffer mechanism 6 is arranged on the sole conveying belt 11, and comprises a first buffer mechanism 61 arranged between the spraying mechanism 4 and the first activation mechanism 71, and a second buffer mechanism 62 arranged between the glue spraying mechanism 5 and the second activation mechanism 72. The first buffer mechanism 61 and the second buffer mechanism 62 have the same structure, and the structure of the second buffer mechanism 62 will be further described.

[0046] The second buffering mechanism 62 is located between the glue spraying mechanism 5 and the second activating mechanism 72, and includes a buffering table 63, a plurality of buffering positions 64, a sole information obtainer 65, a moving piece 66, a pushing piece 67 and a blocking piece 68. The sole conveying belt 11 is provided with a mounting area 14 extending downward for mounting the buffering table 63. The plurality of buffering positions 64 are arranged on the buffering table 63 in a direction perpendicular to the sole conveying direction, and are used for receiving soles. Specifically, the plurality of buffering positions 64 and the read sole information form a one-to-one correspondence relationship. Assuming that the buffering positions 64 are numbered 1-10, when a sole enters a certain buffering position 64, the buffering position 64 is temporarily assigned a value, which is the read sole information. For example, if the sole information is an 8-inch left-foot sole and enters the No. 1 buffering position, then 1 = 8-inch left-foot sole. If the sole information is an 8-inch right-foot sole and enters the No. 2 buffering position, then 2 = 8-inch right-foot sole. Other soles entering the buffering positions 64 are assigned values in the same way. It should be noted that any of the plurality of buffering positions 64 can be assigned to different soles, and the priority of the buffering positions 64 is that the buffering position 64 closest to the sole to be buffered has the highest priority.

[0047] The sole information obtainer 65 is arranged on the sole conveying belt 11 in front of the buffering table 63, and is used for obtaining the information recorded by the sole RFID card 13. The sole information obtainer 65 includes a first bracket 651 arranged on the side of the sole conveying belt 11, and a sole RFID reader-writer 652 arranged on the first bracket 651 and used for reading the information recorded by the sole RFID card 13.

[0048] The moving piece 66 is arranged in the mounting area 14, and is connected and driven to move the buffering table 63 back and forth in a direction perpendicular to the sole conveying direction. The moving piece 66 includes a moving slide rail 661 extending in a direction perpendicular to the sole conveying direction, a sliding block 662 movably arranged on the moving slide rail 661 and connected with the buffering table 63, a moving motor 663 arranged on the moving slide rail 661 and used for driving the sliding block 662 to move, a transmission assembly connected between the sliding block 662 and the moving motor 663, and two proximity sensors 664 arranged at both ends of the moving slide rail 661. The moving motor 663, the transmission assembly and the sliding block 662 are matched to adjust the position of the buffering table 63 so that the defined buffering position 64 is opposite to the inlet of the second activating mechanism 72.

[0049] The pushing member 67 is arranged above the sole conveying belt 11 to push the sole on the corresponding buffer position 64 into the second activation mechanism 72; it comprises a pushing frame 671 arranged above the installation area 14, a pushing table 672 arranged on the pushing frame 671 and movable along the sole conveying direction, a pushing plate arranged on the bottom of the pushing table and movable along the sole advancing direction and swinging unidirectionally, and a pushing cylinder 673 arranged on the pushing frame 671 and connected to drive the pushing table 672 to move; specifically, the pushing plate comprises a first pushing plate 674 and a second pushing plate 675 arranged at intervals along the front and back of the sole conveying direction, and the distance between the first pushing plate 674 and the second pushing plate 675 is greater than the length of one tray 12 and less than the sum of the lengths of two trays 12, so that when the first pushing plate 674 and the second pushing plate 675 swing back and forth once, only one tray 12 can be brought into the corresponding buffer position; when the pushing plate is working, the pushing cylinder 673 drives the pushing table 672 to move so that the second pushing plate 675 pushes the sole on the buffer position 64 into the activation mechanism 7, and at the same time the first pushing plate 674 pushes the standby sole on the sole conveying belt 11 into the opposite buffer position 64, thereby completing the pushing out of the current sole and the pushing in of the standby sole at one time, effectively improving the work efficiency; further, the first pushing plate 674 is arranged at intervals between the two first pushing plates 674 arranged on the bottom of the pushing table 672, and the second pushing plate 675 is opposite the central area between the two first pushing plates 674.

[0050] The blocking member 68 comprises a blocking frame 681 arranged on the sole conveying belt 11 between the buffer table 63 and the sole information reader 65, a blocking plate 682 movable back and forth along the direction perpendicular to the sole conveying direction, and a blocking cylinder 683 arranged on the blocking frame 681 and connected to drive the blocking plate 682 to move back and forth; when the plurality of buffer positions 64 are fully loaded, the blocking cylinder 683 controls the blocking plate 682 to move outward, preventing the sole on the sole conveying belt 11 from continuing to move forward, thereby affecting the work of the moving member 66 and the pushing member 67.

[0051] The upper code reading mechanism 8 is arranged at intervals on the upper conveying belt 21 and located in front of the first activation mechanism 71 and the second activation mechanism 72 respectively to obtain the size information and left-right foot information of the upper entering the first activation mechanism 71 or the second activation mechanism 72; it comprises a third support 81 arranged on the side of the upper conveying belt 21 and an RFID reader-writer 82 arranged on the third support 81 to read the information of the upper RFID card 23.

[0052] The tray recycling mechanism 9, arranged behind the second activating mechanism 72, comprises a data eraser 91 for erasing the information recorded in the sole RFID card 13 and a recycling basket 92 arranged at the end of the sole conveying belt 11 for recycling the tray 12. The data eraser 91 is arranged to erase the information of the sole RFID card 13 to ensure the accuracy of the information of the next production. Specifically, the data eraser 91 is a device commonly used in the field of RFID card data erasing, and its specific structure and working principle will not be further described here.

[0053] The control mechanism 0 is connected with and controls the sole conveying mechanism 1, the upper conveying mechanism 2, the information acquisition and initial matching mechanism 3, the spraying mechanism 4, the glue spraying mechanism 5, the buffer mechanism 6, the activating mechanism 7 and the tray recycling mechanism 9, and comprises a PLC controller connected with the sole conveying mechanism 1, the upper conveying mechanism 2, the information acquisition and initial matching mechanism 3, the spraying mechanism 4, the glue spraying mechanism 5, the buffer mechanism 6 and the activating mechanism 7 respectively and a display screen 01 connected with the PLC controller for displaying corresponding information.

[0055] Initial matching of soles and uppers

[0056] The upper conveying mechanism 21 conveys the upper to the upper information acquirer 31, acquires the code number information and left-right foot information of the upper through the upper RFID card 23, feeds back the acquired information to the control mechanism 0, and then places the corresponding sole in the corresponding tray 12 according to the information displayed by the control mechanism 0, and then the code number information and left-right foot information of the sole are recorded in the sole RFID card 13 by the code writer 32. At this time, the one-to-one relationship between the sole and the tray 12 and the sole and the upper is established, and the initial matching of the sole and the upper is completed.

[0057] Precise matching of soles and uppers

[0058] When the processing agent is sprayed

[0059] The shoe sole conveying belt 11 and the shoe upper conveying belt 12 respectively send the shoe upper and the shoe sole into the spraying mechanism 4 for treatment agent spraying treatment, the shoe sole after treatment firstly obtains the code number information and the left and right foot information through the shoe sole information obtainer 65, and then enters the buffer position 64, so that the plurality of buffer positions 64 and the shoe sole information form a one-to-one correspondence relationship; before the shoe upper after spraying the treatment agent enters the first activation mechanism 71, the shoe upper obtains the code number information and the left and right foot information through the shoe upper code reading mechanism 8, and waits at the entrance of the first activation mechanism 71 to enter the matching with the shoe sole, after the shoe upper information obtained through the shoe upper code reading mechanism 8 is matched with the shoe sole on the first buffer mechanism 61, the moving piece 66 cooperates with the buffer table 63 to automatically call the shoe sole of the corresponding buffer position 64, and the matched shoe sole is sent into the first activation mechanism 71 through the pushing piece 67, and the shoe upper enters the first activation mechanism 71 together to be activated, so that the shoe sole and the shoe upper are precisely matched for the first time;

[0060] When spraying glue

[0061] The shoe sole conveying belt 11 and the shoe upper conveying belt 12 respectively send the shoe upper and the shoe sole into the glue spraying mechanism 5 for glue spraying treatment, the shoe sole after glue spraying treatment firstly obtains the code number information and the left and right foot information through the shoe sole information obtainer 65, and then enters the buffer position 64, so that the plurality of buffer positions 64 and the shoe sole information form a one-to-one correspondence relationship; before the shoe upper after spraying the glue enters the second activation mechanism 72, the shoe upper obtains the code number information and the left and right foot information through the shoe upper code reading mechanism 8, and waits at the entrance of the second activation mechanism 72 to enter the matching with the shoe sole, after the shoe upper information obtained through the shoe upper code reading mechanism 8 is matched with the shoe sole on the buffer mechanism 6, the moving piece 66 cooperates with the buffer table 63 to automatically call the shoe sole of the corresponding buffer position 64, and the matched shoe sole is sent into the second activation mechanism 72 through the pushing piece 67, and the shoe upper enters the second activation mechanism 72 together to be activated, so that the shoe sole and the shoe upper are precisely matched for the second time;

[0062] Shoe sole and shoe upper forming

[0063] The activated shoe sole and the shoe upper are compacted by artificial to obtain finished shoes, and the tray 12 is cleaned by the data cleaner 911 to clean the information in the shoe sole RFID card 13 in the tray 2, so as to ensure the accuracy of the information of the next production.

[0064] In the process of precise matching of the shoe sole and the shoe upper, when the shoe sole or the shoe upper has overflow glue, blocked glue and other phenomena, manual intervention is needed for processing. At this time, the shoe sole and the corresponding tray 12 or the shoe upper with problems are taken out by hand for processing. When the shoe sole has problems, the shoe upper is sprayed with glue and then matched with the corresponding shoe sole through the buffer mechanism 6. If the shoe sole is missing, the control mechanism 0 prompts that the corresponding shoe sole needs to be supplemented or the opposite shoe upper is removed from the shoe upper conveying belt. When the shoe upper has problems, the shoe sole is directly stored in the buffer position 64, which does not affect the automatic matching of the shoe sole and the shoe upper. After the shoe upper is processed, it is put back on the shoe upper conveying belt 21 and matched with the corresponding shoe sole.

[0065] In the process of precise matching of the shoe sole and the shoe upper, when multiple buffer positions simultaneously have shoe soles with the same code number and left-right foot information, the control mechanism 0 controls the moving part 66 to cooperate with the buffer table 63 to make the shoe sole with the longest storage time enter the activation mechanism 7 first to be matched with the shoe upper.

[0066] The application specifically limits the structure of the shoe sole and shoe upper matching device, adds a buffer mechanism, and further limits the structure of the buffer mechanism to cooperate with other mechanisms to solve the problem of matching of the shoe sole and the shoe upper in the existing intelligent line / traditional line. It can also solve the problem of simultaneous taking and placing of the shoe sole / shoe upper due to overflow glue, insufficient glue and blocked glue. It can also solve the problem of incorrect bottoming caused by chaotic matching of the shoe sole and the shoe upper, reduce the scrap rate of shoes, and achieve efficient production of the production line.

[0067] The above is only a preferred embodiment of the application, and therefore cannot limit the scope of the application. Equivalent changes and modifications made in accordance with the scope and content of the application should still be within the scope of the application.

The method comprises the following operations: Initial matching of soles and uppers The upper conveying mechanism conveys the upper to the upper information acquirer, the size information and the left-right foot information of the upper are acquired through the upper RFID card, the acquired information is fed back to the control mechanism, the corresponding sole is placed in the corresponding tray according to the information displayed by the control mechanism, the size information and the left-right foot information of the sole are recorded in the sole RFID card through the code writer, and the relationship between the sole and the tray and the relationship between the sole and the upper are established, and the initial matching of the sole and the upper is completed. Precise matching of soles and uppers The shoe sole conveying belt and the shoe upper conveying belt respectively send the shoe upper and the shoe sole into the glue spraying mechanism for glue spraying treatment. The shoe sole after the glue spraying treatment is firstly sent into the buffer position through the shoe sole information acquisition device to obtain the code number information and the left and right foot information, so that the plurality of buffer positions and the shoe sole information form a one-to-one correspondence relationship. Before the shoe upper sprayed with glue enters the activation mechanism, the shoe upper obtains the code number information and the left and right foot information through the shoe upper code reading mechanism, and waits at the entrance of the activation mechanism to be matched with the shoe sole to enter the activation mechanism. After the shoe upper information obtained through the shoe upper code reading mechanism is matched with the shoe sole on the buffer mechanism, the moving part cooperates with the buffer table to automatically call the shoe sole in the corresponding buffer position, and the matched shoe sole is sent into the activation mechanism through the pushing part to enter the activation mechanism together with the shoe upper to activate, so that the shoe sole and the shoe upper are accurately matched. In the process of accurately matching the shoe sole and the shoe upper, when the shoe sole or the shoe upper has glue overflow or glue blockage phenomenon and needs manual intervention for treatment, the problematic shoe sole and the corresponding tray or the shoe upper are taken out by hand for treatment. If the problematic part is the shoe sole, the corresponding shoe sole is matched with the shoe upper sprayed with glue through the buffer mechanism. If the shoe sole is missing, the control mechanism prompts that the corresponding shoe sole needs to be supplemented or the opposite shoe upper is removed from the shoe upper conveying belt. If the problematic part is the shoe upper, the shoe sole is directly stored in the buffer position, which does not affect the automatic matching of the subsequent shoe sole and shoe upper. After the shoe upper is treated, it is re-placed on the shoe upper conveying belt to be matched with the corresponding shoe sole.
