Description

Technical Field

[0001] The present invention relates to the field of shoe material processing technology, in particular to a shoe upper position indicating device and a shoe upper position indicating method. Background Art

[0002] See also Figure 1 As shown, the process of combining a sole 11 and an upper 12 generally includes the following steps:

[0003] 1. Boardlasting: The upper 12 is put into a last 13 to shape the upper 12.

[0004] 2. Lasting: combining a midsole 111 of the sole 11 with the upper 112 .

[0005] 3. Attaching the outsole: bonding a large bottom layer 112 of the sole 11 to the upper 12 and the mid-bottom layer 111 , so that the sole 11 including the mid-bottom layer 1111 and the large bottom layer 112 is combined with the upper 12 .

[0006] The aforementioned step of pulling the upper is mainly performed manually or by a machine (not shown). However, since the position of the upper 12 relative to the last 13 determines the appearance of the finished product and affects the comfort, whether the pulling is performed manually or by a machine, it is necessary to rely on experienced craftsmen to judge the quality after pulling the upper. This is not only time-consuming and labor-intensive, but also difficult to train manpower. Different judgment results may occur due to different experience values, resulting in unstable quality control.

[0007] In order to improve the quality of the upper, there are many methods and structures on the market that can determine whether the upper position is normal during the upper process, such as Taiwan Patent Publication No. 201912109 and No. M573594U. However, when the upper of the aforementioned public cases is judged to be abnormal, the abnormal information is displayed on the display of the machine. Therefore, during the upper process, the operator needs to keep looking up to see the abnormal information on the display to know that the abnormality has occurred. Moreover, since the abnormal information is often in the form of numbers or text, the operator cannot intuitively react to how to adjust the upper, which makes the adjustment process of the upper quite inconvenient and time-consuming. Summary of the invention

[0008] In view of this, the present invention aims to solve the deficiencies in the prior art, and its main purpose is to provide a shoe upper position indicating device and a shoe upper position indicating method thereof, which can intuitively and quickly adjust the shoe upper.

[0009] To achieve the above purpose, the present invention adopts the following technical solutions:

[0010] A method for indicating the position of a shoe upper, wherein the shoe upper can be operably placed on a shoe last and displaced between an abnormal position and a normal position relative to the shoe last. When in the abnormal position, the shoe upper is at least partially offset from the shoe last. When in the normal position, the shoe upper is fully matched with the shoe last. The method for indicating the position of the shoe upper comprises the following steps:

[0011] Step a: projecting a reference light spot according to a default fixed point position, the reference light spot being applicable to overlap a characteristic part of the shoe upper when the shoe upper is put on the last;

[0012] Step b: Based on a result of the position recognition of the shoe upper, when the shoe upper is located at the abnormal position, an indication light spot is projected on the shoe upper, and the indication light spot is suitable for indicating the moving direction of the shoe upper until the shoe upper is located at the normal position.

[0013] As a preferred solution, the indicating light spot in step b disappears after the shoe upper moves to the normal position.

[0014] As a preferred solution, the reference light spot is a cross symbol.

[0015] As a preferred solution, the indicator light spot is one of an up arrow, a down arrow, a left arrow, a right arrow, a right-handed arrow, and a left-handed arrow.

[0016] As a preferred solution, the projected reference light spot and the indicator light spot come from a projector.

[0017] As a preferred solution, the projected reference light spot and the indicator light spot are transformed into different colors.

[0018] As a preferred solution, the projected reference light spot and the indicator light spot are transformed into different sizes.

[0019] A shoe upper position indicating device, wherein the shoe upper can be operably mounted on a shoe last and displaced between an abnormal position and a normal position relative to the shoe last. When in the abnormal position, the shoe upper at least partially deviates from the shoe last. When in the normal position, the shoe upper and the shoe last are fully matched. The shoe upper position indicating device comprises:

[0020] a projection unit, used for projecting a reference light spot and an indication light spot, wherein the reference light spot is applicable to overlap a characteristic part of the shoe upper when the shoe upper is put on the last, and the indication light spot is applicable to indicate the moving direction of the shoe upper; and

[0021] A processing unit controls the projection unit to generate a reference light spot projected on the fixed point according to a default fixed point position, and when the shoe upper is located at the abnormal position, controls the projection unit to generate an indication light spot projected on the shoe upper according to a shoe upper position recognition result until the shoe upper is located at the normal position.

[0022] As a preferred solution, the processing unit controls the projection unit to stop generating the indication light spot when the shoe upper is in the normal position.

[0023] As a preferred solution, the reference light spot is a cross symbol.

[0024] As a preferred solution, the indicator light spot is one of an up arrow, a down arrow, a left arrow, a right arrow, a right-handed arrow, and a left-handed arrow.

[0025] As a preferred solution, the projection unit includes a projector.

[0026] As a preferred solution, the projected reference light spot and the indicator light spot are changed into different colors and different sizes.

[0027] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0028] When the operator operates the shoe upper to fit on the last, the operator can intuitively adjust the position of the shoe upper quickly through the reference light spot and the indicator light spot on the shoe upper without looking up, thereby effectively shortening the process time.

[0047] Please refer to Figures 2 to 4 As shown in FIG. 1 , the specific structure of the upper position indicating device of the preferred embodiment of the present invention is shown, which is suitable for being installed in a fore-lasting machine 2. The fore-lasting machine 2 is used to insert a vamp 31 into a last 32 installed in the fore-lasting machine 2, and includes a plurality of clamps 21 for positioning the vamp 31. The vamp 31 can be operated to be in an abnormal position (such as Figure 2 ) and a normal position (such as Figure 4 ) and has a characteristic portion 311 that can be eliminated. In the present embodiment, the characteristic portion 311 is a painted double cross symbol. When in the abnormal position, the upper 31 is at least partially offset from the last 32, and when in the normal position, the upper 31 is fully matched with the last 32. In the present embodiment, the operator operates the clamping jaws 21 of the upper lasting machine 2 to move the upper 31, and the basis for judging whether the upper 31 is in the normal position or the abnormal position can be the upper position recognition result of the identification device and identification method for the upper assembly operation of Taiwan Patent Publication No. 201912109, or the upper position recognition result of the upper detection device of No. M573594U.

[0048] The shoe upper position indicating device comprises a projection unit 4 and a processing unit 5 .

[0049] In this embodiment, the projection unit 4 includes a projector (Digital Light Processing, DLP) 41 installed on the front side machine 2 and an image capture module 42 .

[0050] The projector 41 is used to generate a reference light spot 411 and an indication light spot 412 projected on the upper 31. In this embodiment, the reference light spot 411 is a cross symbol. The indication light spot 412 can be one of an up arrow, a down arrow, a left arrow, a right arrow, a right-handed arrow, and a left-handed arrow.

[0051] The image capturing module 42 is used to capture an image 441 of the upper 31 and the last 32 .

[0052] The processing unit 5 is connected to the projector 41 and the image capture module 42 through wired or wireless communication technology, and controls the projector 41 to generate a reference light spot 411 projected on the shoe upper 31 according to a default fixed point position, and when the shoe upper 31 is located at the abnormal position, controls the projector 41 to generate an indication light spot 412 projected on the shoe upper 31 according to the aforementioned shoe upper position recognition result.

[0053] See also Figure 5 , Figure 2 and Figure 4 The shoe upper position indication method of the present invention performs the following steps through the processing unit 5:

[0054] Step 601: According to the default fixed point position, control the projector 41 to generate the reference light spot 411 projected at the fixed point position, so that the operator can align the characteristic part 311 of the upper 31 with the reference light spot 411, and put the upper 31 on the last 32 to make the reference light spot 411 overlap with the characteristic part 311.

[0055] It is worth noting that the aforementioned reference light spot 411 projected at the fixed point position can be pre-projected on the upper 31, and then the last 32 is operated to move relative to the upper 31 to fit with the upper 31, or projected on the last 32, and then the upper 31 is operated to move relative to the last 32 to fit with the last 32.

[0056] Step 602: Based on the above-mentioned upper position identification result, determine whether the upper 31 is located in a normal position. If yes, proceed to step 604; if not, proceed to step 603.

[0057] It should be noted that the aforementioned upper position identification result is not limited to being generated by the identification device and identification method of the upper assembly operation as disclosed in Taiwan Patent Publication No. 201912109, or by the upper detection device as disclosed in Case No. M573594U, but may also be other methods or structures capable of identifying the position of the upper 31.

[0058] Step 603: Based on the above-mentioned upper position recognition result, control the projector 41 to generate an indication light spot 412 projected on the upper 31 to indicate the moving direction of the upper 31, so that the operator can operate the clamping jaw 21 of the upper lasting machine 2 to move the upper 31, and then return to step 602.

[0059] For example, when the above-mentioned upper position recognition result determines that the upper 31 is offset to the right relative to the last 32, the processing unit 5 will control the projector 41 to generate an indication light spot 412 in the form of a right arrow projected on the upper 31. At this time, the operator can intuitively operate the clamping jaw 21 of the upper lasting machine 2 to move the upper 31 to the right while watching the upper 31 without raising his head.

[0060] Step 604: Control the projector 41 to stop generating the indicator light spot 412. This indicates that the upper 31 is located at the normal position and is fully matched with the last 32, and the subsequent lasting operation can be performed.

[0061] See also Figure 6 For example, when the above-mentioned upper position recognition result determines that the upper 31 is offset to the left relative to the last 32, the processing unit 5 will control the projector 41 to generate an indication light spot 412 in the form of a left arrow projected on the upper 31. At this time, the operator can intuitively operate the clamping jaw 21 of the upper lasting machine 2 to move the upper 31 to the left. If the displacement is insufficient, the projector 41 will continue to generate a left arrow projected on the upper 31 until the upper 31 is in the normal position.

[0062] It should be noted that the indicator light spot 412 is not limited to being a right arrow or a left arrow. In other aspects of this embodiment, it may also be Figure 7 As shown by the up arrow, or as Figure 8 As shown by the down arrow, or as Fig. 9 A right-hand arrow, or Fig.10 A left-hand arrow or other symbols, words, etc. that can indicate direction are shown.

[0063] Through the above description, the advantages of the above embodiments can be summarized as follows:

[0064] 1. The present invention enables the operator to quickly adjust the position of the upper 31 by intuitively adjusting the reference light spot 411 and the indicator light spot 412 on the upper 31 when fitting the upper 31 on the last 32 without raising his head, thereby effectively shortening the process time.

[0065] 2. Importantly, the reference light spot 411 and the indicator light spot 412 can change color and size at will, so that the reference light spot 411 or the indicator light spot 412 can be clearly distinguished from the color of the shoe upper 31, or more prominent, and easier to identify.

[0066] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
