Description

Technical Field

[0001] The invention belongs to the field of shoemaking, and in particular relates to a sole-attaching diversion method and a device. Background Art

[0002] As one of the processes in the shoe production line, sole pasting is Fig. 9 As shown, after the upper and sole are glued and activated in the oven, the sole-pasting personnel will stick the dried soles to the uppers together. After the sole-pasting is completed, the shoes will be transported to the sole-pressing process for sole-pressing. The working method of the existing production line is to place the shoe lasts after sole-pasting on the discharge positions on the left and right sides of the accompanying fixture, and transport them to the sole-pressing station through the conveying system for sole-pressing. In order to meet actual production needs, the existing sole-pasting process is set up with two-person and multi-person modes. In the two-person mode, after the shoe last on the accompanying fixture is taken away, the accompanying fixture will be automatically released. The reason for this setting is that the next upper to be sole-pasted needs to flow to the picking position, so that after the sole of the current upper is manually pasted and placed on the accompanying fixture, the next upper can be directly taken, thereby ensuring production efficiency. However, this operation has disadvantages, that is, when a worker leaves for a short time and returns to continue to stick the sole or is about to leave work, the accompanying fixture is automatically released, so there is no accompanying fixture to place the upper that has been stuck to the sole. The worker must take the upper to the sole pressing station by himself, which not only greatly reduces the production efficiency of the production line, but also does not meet the production specifications of the production line. As for the multi-person mode, the existing production line replicates the two-person mode, that is, the accompanying fixture automatically flows away after the material is taken. This still has the problem that when the worker leaves for a short time and returns, there is no accompanying fixture to place the upper after the sole is stuck. Summary of the invention

[0003] The purpose of the present invention is to propose a method and device for diverting shoe lasts after sole sticking, so that when a worker leaves for a short time and returns, there is always an idle accompanying fixture waiting to place the shoe last after sole sticking, thereby effectively improving the production efficiency of the production line and meeting the production specifications of the production line.

[0004] The present invention is achieved through the following technical solutions:

[0005] A bottom-attaching diversion method is used to ensure that there is always an idle accompanying fixture that is blocked on the conveyor line. The accompanying fixture has a clamp located in the middle for placing shoe lasts without soles attached and two material placement positions located on both sides of the clamp for placing shoe lasts with soles attached. The conveyor line has multiple fixture positions, and the fixture position located between the first manual position and the second manual position is numbered as the second fixture position, and the next fixture position along the conveyor line direction is numbered as the first fixture position. The bottom-attaching diversion method includes the following steps:

[0006] Step S11, each accompanying fixture with material flows between fixture positions along the conveyor line, and is blocked when it flows to the No. 2 fixture position. The first worker removes the unsoled shoe last from the accompanying fixture with material located at the No. 2 fixture position and performs the sole-sticking operation. The accompanying fixture with material becomes an idle accompanying fixture, is released, and flows to the No. 1 fixture position and is then blocked;

[0007] Step S12, the second manual worker takes the unsoled shoe last from the traveling fixture with material located at the No. 2 fixture position and performs the sole-sticking operation, and the traveling fixture with material becomes an idle traveling fixture. When there are two consecutive idle traveling fixtures, the idle traveling fixture in front along the flow direction of the conveyor line is released, and the next traveling fixture is blocked, that is, the No. 1 fixture position releases the previous idle traveling fixture, and the current idle traveling fixture flows to the No. 1 fixture position and is blocked;

[0008] Step S13, the first worker or the second worker places the shoe last with the sole attached on the discharge position of the idle accompanying fixture of the No. 1 fixture position. If there is only one discharge position for placing the shoe last, the idle accompanying fixture is still blocked. When the shoe last is placed on both discharge positions, the idle accompanying fixture becomes a full accompanying fixture, and the full accompanying fixture is released, and then enters step S11 to perform the next cycle.

[0009] Furthermore, the conveyor line is provided with a plurality of two-person mode groups formed by a first worker and a second worker.

[0010] Furthermore, the conveyor line is provided with a first detection mechanism corresponding to the position of the second clamp and a second detection mechanism corresponding to the position of the first clamp. The first detection mechanism includes a first sensor, a second sensor and a third sensor. The first sensor is used to detect whether there is a shoe last on the clamp of the accompanying clamp located at the second clamp position. The second sensor and the third sensor are respectively used to detect whether there is a shoe last on the two discharge positions of the accompanying clamp located at the second clamp position. The second detection mechanism includes a fourth sensor and a fifth sensor. The fourth sensor and the fifth sensor are respectively used to detect whether there is a shoe last on the discharge position of the accompanying clamp located at the first clamp position.

[0011] The shoe last is clamped in the upper and lower parts of the shoe body, and the two shoe bodies are connected with the shoe body to form a circle around the shoe body, and the two shoe bodies are connected with the shoe body to form a circle around the shoe body.

[0012] Furthermore, two spaced grooves are formed at the lower end of the push plate, a limiting screw hole is arranged between the two grooves, and limiting nuts are arranged in the limiting screw holes from bottom to top. When the push plate is completely pushed back to the support block, the limiting nut contacts the block.

[0013] Furthermore, two blocking mechanisms and two proximity sensors are provided on the conveyor line, and the two blocking mechanisms correspond to the clamp position No. 1 and the clamp position No. 2 respectively. The blocking mechanism includes a second bracket arranged horizontally at the lower end of the conveyor line, a second telescopic member arranged vertically on the second bracket and extendable upward, a blocking block arranged at the upper end of the second telescopic member, and a blocking groove arranged at the lower end of the accompanying clamp for inserting the blocking block. When the accompanying clamp passes the proximity sensor, the second telescopic member extends upward to allow the blocking block to be inserted into the blocking groove, thereby blocking the accompanying clamp.

[0014] The present invention is also achieved through the following technical solutions:

[0015] A bottom-sticking diversion device based on any of the bottom-sticking diversion methods as described above, used to ensure that there is always a blocked idle accompanying fixture on the conveyor line, the accompanying fixture has a clamp located in the middle for placing unsoled shoe lasts and two discharge positions located on both sides of the clamp for placing shoe lasts with soles attached, including a control center, a plurality of fixture positions arranged on the conveyor line, a first detection mechanism and a second detection mechanism arranged on the conveyor line, two blocking mechanisms, two proximity sensors and a first release mechanism, the first detection mechanism corresponds to one of the fixture positions, the second detection mechanism corresponds to the adjacent fixture position of the fixture position along the conveyor line direction, the two blocking mechanisms correspond to the two adjacent fixture positions respectively, and the first release mechanism corresponds to one of the fixture positions. The first detection mechanism and the second detection mechanism are respectively connected to the input end of the control center to detect whether the accompanying fixture on the corresponding fixture position is a traveling fixture with material, an idle traveling fixture or a full traveling fixture. The proximity sensor is connected to the input end of the control center to detect whether there is a traveling fixture passing by. The output end of the control center is connected to the blocking mechanism and the first releasing mechanism. According to the detection results of the first detection mechanism, the second detection mechanism and the proximity sensor, the actions of the blocking mechanism and the first releasing mechanism are controlled to block the traveling fixture with material, block the idle traveling fixture, release the idle traveling fixture in front and block the idle traveling fixture in the back when there are two consecutive idle traveling fixtures, and release the full traveling fixture.

[0016] The present invention is also achieved through the following technical solutions:

[0017] A bottom-attaching diversion method is used to ensure that there is always an idle accompanying fixture that is blocked on a conveyor line. The accompanying fixture has a clamp located in the middle for placing shoe lasts that are not attached to the sole and two material discharge positions located on both sides of the clamp for placing shoe lasts that have been attached to the sole. The conveyor line has multiple fixture positions. The fixture position located between a first manual position and a second manual position is numbered as a second fixture position. The next fixture position of the second fixture position along the conveyor line direction is numbered as a first fixture position. The upper three fixture positions are numbered as a third fixture position, a fourth fixture position and a fifth fixture position, respectively. The fixture position located between a third manual position and a fourth manual position is numbered as a sixth fixture position. The upper three fixture positions of the sixth fixture position along the conveyor line direction are numbered as a seventh fixture position, an eighth fixture position and a ninth fixture position, respectively. The bottom-attaching diversion method comprises the following steps:

[0018] Step S21, each accompanying fixture with material flows between the fixture positions along the conveyor line, and the accompanying fixture with material on the sixth fixture position and the fifth fixture position is controlled not to be blocked, until the second to fifth fixture positions all have accompanying fixtures with material, and the accompanying fixtures with material on the second and sixth fixture positions are controlled to be blocked, the first manual person removes the unsoled shoe last from the accompanying fixture with material at the second fixture position and performs the sole attaching operation, and the accompanying fixture with material becomes an idle accompanying fixture, and the third manual person removes the unsoled shoe last from the accompanying fixture with material at the sixth fixture position and performs the sole attaching operation Operation, the traveling fixture with material becomes an idle traveling fixture, the idle traveling fixture at the No. 2 fixture position is released and flows to the No. 1 fixture position and then is blocked, the idle traveling fixture at the No. 6 fixture position is released and flows to the No. 5 fixture position and then is blocked, the traveling fixtures with material at the No. 3 fixture position and the No. 7 fixture position flow to the No. 2 fixture position and the No. 6 fixture position respectively, the traveling fixtures with material at the No. 4 fixture position and the No. 8 fixture position flow to the No. 3 fixture position and the No. 7 fixture position respectively, the traveling fixtures with material at the No. 5 fixture position and the No. 9 fixture position flow to the No. 4 fixture position and the No. 8 fixture position;

[0019] Step S22, the second worker removes the unsoled shoe last from the accompanying fixture with material at the No. 2 fixture position and performs the sole attaching operation, and the accompanying fixture with material becomes an idle accompanying fixture, and the fourth worker removes the unsoled shoe last from the accompanying fixture with material at the No. 6 fixture position and performs the sole attaching operation, and the accompanying fixture with material becomes an idle accompanying fixture. When there are two consecutive idle accompanying fixtures, the idle accompanying fixture in front of the conveyor line flow direction is released, and the latter accompanying fixture is blocked, that is, the original idle accompanying fixture at the No. 1 fixture position is released, and the No. 2 fixture is The current idle accompanying fixture of the fixture position is released and flows to the No. 1 fixture position and then is blocked, the original material accompanying fixture of the No. 3 fixture position flows to the No. 2 fixture position, the original material accompanying fixture of the No. 4 fixture position flows to the No. 3 fixture position, the original idle accompanying fixture of the No. 5 fixture position is released and flows to the No. 4 fixture position, the current idle accompanying fixture of the No. 6 fixture position is released and flows to the No. 5 fixture position and then is blocked, the original material accompanying fixture of the No. 7 fixture position flows to the No. 6 fixture position, and the original material accompanying fixture of the No. 8 fixture position flows to the No. 7 fixture position;

[0020] Step S23, the first worker and the second worker respectively place the shoe last with the sole attached on the unloading position of the idle accompanying fixture of the No. 1 fixture position, at which time the idle accompanying fixture of the No. 1 fixture position becomes a full accompanying fixture, the third worker and the fourth worker respectively place the shoe last with the sole attached on the unloading position of the idle accompanying fixture of the No. 5 fixture position, at which time the idle accompanying fixture of the No. 5 fixture position becomes a full accompanying fixture, and the first worker and the third worker respectively place the shoe last with the sole attached on the unloading position of the idle accompanying fixture of the No. 5 fixture position, at which time the idle accompanying fixture of the No. 5 fixture position becomes a full accompanying fixture, and the shoe last is not attached to the shoe last until the first worker and the third worker place the shoe last. After taking off the shoe lasts at the No. 2 fixture and the No. 6 fixture, the idle accompanying fixtures at the No. 2 fixture and the No. 6 fixture flow to the No. 1 fixture and the No. 5 fixture respectively, the original full accompanying fixture at the No. 5 fixture flows to the No. 4 fixture, the original idle accompanying fixture at the No. 4 fixture flows to the No. 3 fixture, the original accompanying fixture at the No. 3 fixture flows to the No. 2 fixture, and the original accompanying fixture at the No. 7 fixture flows to the No. 6 fixture;

At this time, fixture position No. 2 does not perform a blocking action, and the conveyor line continues to operate until the full accompanying fixture at fixture position No. 4 flows to fixture position No. 1. At this time, fixture position No. 2 and fixture position No. 6 welcome new accompanying fixtures with material, and enter step S21 for the next cycle.

[0022] Furthermore, the conveyor line is provided with a plurality of four-person bottom-pasting groups consisting of a first worker to a fourth worker.

[0023] Furthermore, the conveyor line is fixedly provided with a first detection mechanism corresponding to the clamp position No. 2 and the clamp position No. 6, and a second detection mechanism corresponding to the clamp position No. 1 and the clamp position No. 5, respectively. The first detection mechanism includes a first sensor, a second sensor and a third sensor. The first sensor is used to detect whether there is a shoe last on the clamp of the accompanying clamp located at the clamp position No. 2 or the clamp position No. 6, the second sensor and the third sensor are used to detect whether there is a shoe last on the two discharge positions of the accompanying clamp located at the clamp position No. 2 or the clamp position No. 6, respectively. The second detection mechanism includes a fourth sensor and a fifth sensor. The fourth sensor and the fifth sensor are used to detect whether there is a shoe last on the discharge position of the accompanying clamp located at the clamp position No. 1 and the clamp position No. 5, respectively.

[0024] The present invention has the following beneficial effects:

[0025] 1. In the two-person mode of the present invention, the first worker first takes off the shoe last on the accompanying fixture with material at the No. 2 fixture position. At this time, the accompanying fixture with material becomes an idle accompanying fixture and is blocked at the No. 1 fixture position. The second worker takes off the shoe last on the accompanying fixture with material currently at the No. 2 fixture position. At this time, there are two consecutive idle accompanying fixtures, so the front idle accompanying fixture is released and the rear idle accompanying fixture is blocked at the No. 1 fixture position. After the first worker and the second worker complete the sole pasting, they put the shoe last into the two material placement positions of the idle accompanying fixture at the No. 1 fixture position respectively. At this time, the idle accompanying fixture becomes a full accompanying fixture and is released, and the process can continue in this way. During the second round of sole pasting, if one person leaves temporarily, the idle accompanying fixture at fixture position No. 1 can be released only after shoe lasts are placed at both material placement positions. Therefore, the worker who has not left can perform the sole pasting work of two consecutive shoe lasts alone. When the worker who has left returns, there is always an idle accompanying fixture waiting at fixture position No. 1, so the worker can directly continue the sole pasting work. In the case that there is no accompanying fixture with material when preparing to get off work, there will also be an idle accompanying fixture waiting, avoiding the problem that the worker has to send the shoe last after sole pasting to the sole pressing process by himself, thereby effectively improving the production efficiency of the production line and complying with the production specifications of the production line.

[0026] 2. For the four-person mode, the concept of the present invention is the same as that of the two-person mode. However, in order to speed up the pace and avoid the situation where the two people in front need to wait for materials after completing the bottoming, four clamp positions are set as a group, and the four clamp positions at the front along the conveyor line are controlled to be allocated with material accompanying clamps first, instead of simply copying the two-person mode, thereby effectively improving the production efficiency of the production line.

DETAILED DESCRIPTION

[0038] Embodiment 1:

[0039] like Figures 1 to 6 As shown, for the two-person mode, the bottom-sticking diversion method is used to ensure that there is always a blocked idle accompanying fixture 2 on the conveyor line, so that when one of the first worker 11 and the second worker 12 arranged along the transmission direction of the conveyor line 1 leaves or is about to go off work, the worker does not have to send the bottom-sticked shoe last 3 to the bottom pressing process by himself due to the lack of an idle accompanying fixture 2. The portable fixture 2 has a clamp 21 located in the middle for placing the shoe last 3 without sole attached and two discharge positions 22 located on both sides of the clamp 21 for placing the shoe last 3 with sole attached. When the shoe last 3 is set on the clamp 21, the portable fixture 2 is a portable fixture 2 with material. When the shoe last 3 on the clamp 21 is removed and the shoe last 3 with sole attached is not placed in the two discharge positions 22, the portable fixture 2 is an idle portable fixture 2. When the shoe last 3 on the clamp 21 is removed and the shoe last 3 with sole attached is placed in the two discharge positions 22, the portable fixture 2 is a full portable fixture 2.

[0040] There are multiple clamp positions on the conveyor line 1, and each accompanying clamp 2 flows between different clamp positions along the conveyor line 1. The clamp position between the first manual 11 and the second manual 12 is numbered as the second clamp position 16, and the next clamp position along the conveyor line 1 is numbered as the first clamp position 15. The conveyor line 1 is provided with a first detection mechanism 4 corresponding to the second clamp position 16 and a second detection mechanism 5 corresponding to the first clamp position 15. The conveyor line 1 is also provided with a first release mechanism 6 corresponding to the second clamp position 16. The conveyor line 1 is provided with two blocking mechanisms 7 and two proximity sensors 71, and the two blocking mechanisms 7 correspond to the first clamp position 15 and the second clamp position 16, respectively.

[0041] Specifically, the first release mechanism 6 includes a first bracket 61 arranged on the conveyor line 1 and extending upward, a first telescopic member 62 arranged longitudinally and horizontally on the first bracket 61, the first telescopic member 62 is a cylinder, and a stop block is arranged at the protruding end of the cylinder, and the clamping member 21 includes a support block 211 arranged on the accompanying fixture 2 and hollow at the bottom, two clamping columns 212 arranged vertically and spaced apart on the support block 211, a shoe last 3 arranged on the upper part of the two clamping columns 212, two springs 213 respectively arranged between the two clamping columns 212 and the accompanying fixture 2, a clamping block 214 arranged horizontally and horizontally on the clamping column 212 and located in the hollow of the support block 211, and a push plate 21 arranged longitudinally and horizontally in the hollow of the support block 211. 5. The push plate 215 has two strip-shaped holes 2151 respectively corresponding to the two clamping columns 212. A clamping groove is formed at the lower end of the push plate 215. The clamping groove has a first inclined surface 2152 extending downward in a direction close to the first telescopic member 62, and a second inclined surface 2153 arranged at the high end of the first inclined surface 2152 and extending downward. When the clamping block 214 is located at the connection between the first inclined surface 2152 and the second inclined surface 2153, the push plate 215 extends out of the support block 211, and the two clamping columns 212 are located at the highest position to clamp the shoe last 3. When the first telescopic member 62 extends to push the push plate 215 back to the support block 211, the first inclined surface 2152 presses the clamping block 214 downward to drive the clamping column 212 to move downward, so that the shoe last 3 can be removed. Two spaced grooves are formed at the lower end of the push plate 215, and a limit screw hole 2154 is arranged between the two grooves. A limit nut 2155 is arranged from bottom to top in the limit screw hole 2154. When the push plate 215 is completely pushed back to the support block 211, the limit nut 2155 contacts the block 214. The specific structure of the clamping column 212 and the clamping column 212 and the shoe last 3 is the prior art.

[0042] The first detection mechanism 4 includes a first sensor 41, a second sensor 42 and a third sensor 43. The first sensor 41 is used to detect whether there is a shoe last 3 on the clamp 21 of the accompanying fixture 2 located at the second fixture position 16. The second sensor 42 and the third sensor 43 are respectively used to detect whether there is a shoe last 3 on the two discharge positions 22 of the accompanying fixture 2 located at the second fixture position 16. More specifically, the first sensor 41, the second sensor 42 and the third sensor 43 are all arranged on the first bracket 61. The second detection mechanism 5 includes a fourth sensor 51 and a fifth sensor 52. The fourth sensor 51 and the fifth sensor 52 are respectively used to detect whether there is a shoe last 3 at the discharge position 22 of the accompanying fixture 2 located at the first fixture position 15.

[0043] The blocking mechanism 7 includes a second bracket 72 disposed horizontally at the lower end of the conveyor line 1, a second telescopic member 73 disposed vertically on the second bracket 72 and capable of extending upward, a blocking block 74 disposed at the upper end of the second telescopic member 73, and a blocking groove 23 disposed at the lower end of the portable fixture 2 for inserting the blocking block 74. When the portable fixture 2 passes the proximity sensor 71, the second telescopic member 73 extends upward to allow the blocking block 74 to be inserted into the blocking groove 23, thereby blocking the portable fixture 2. In this embodiment, the second telescopic member 73 may be a cylinder.

[0044] In order to realize the control of the portable fixture 2, a control center is also provided in this embodiment, the first detection mechanism 4, the second detection mechanism 5 and the proximity sensor 71 are respectively connected to the input end of the control center, and the output end of the control center is connected to the blocking mechanism 7 and the first release mechanism 6, and the actions of the blocking mechanism 7 and the first release mechanism 6 are controlled according to the detection results of the first detection mechanism 4, the second detection mechanism 5 and the proximity sensor 71. The control center can be an industrial computer or a CPU.

[0045] like Figure 7 As shown, the bottom diversion method includes the following steps:

[0046] Step S11, each carrying fixture 2 with material flows between fixture positions along the conveyor line 1, and is blocked by the corresponding blocking mechanism 7 when it flows to the second fixture position 16, the first releasing mechanism 6 is actuated to enable the shoe last 3 of the carrying fixture 2 with material at the second fixture position 16 to be removed, the first manual operation 11 removes the unsoled shoe last 3 and performs a sole-sticking operation, the carrying fixture 2 with material becomes an idle carrying fixture 2, is released, and flows to the first fixture position 15, and is blocked by the corresponding blocking mechanism 7, the second fixture position 16 welcomes a new carrying fixture 2 with material and blocks the new carrying fixture 2 with material;

[0047] Step S12, the second worker 12 removes the unsoled shoe last 3 from the traveling fixture 2 with material located at the second fixture position 16 and performs the sole-sticking operation, and the traveling fixture 2 with material becomes an idle traveling fixture 2. When there are two consecutive idle traveling fixtures 2, the idle traveling fixture 2 in front of the conveyor line 1 in the flow direction is released, and the next traveling fixture 2 is blocked, that is, the first fixture position 15 releases the previous idle traveling fixture 2, and the current idle traveling fixture 2 flows to the first fixture position 15 and is blocked;

[0048] Step S13, the first worker 11 or the second worker 12 places the shoe last 3 with the sole attached on the discharge position 22 of the idle accompanying fixture 2 of the first fixture position 15 (the shoe last 3 with the sole attached is placed facing down). If there is only one discharge position 22 for placing the shoe last 3, the idle accompanying fixture 2 is still blocked. When the shoe last 3 is placed in the two discharge positions 22, the idle accompanying fixture 2 becomes a full accompanying fixture 2, and the full accompanying fixture 2 is released, and then enters step S11 for the next cycle.
