Detailed Description

Fig. 2 to 4 show the specific structure of the vamp position indicating device of the preferred embodiment of the present invention, which is suitable for being installed on a front upper machine 2. The toe lasting machine 2 is used for sleeving a shoe upper 31 on a last 32 of the toe lasting machine 2 and comprises a plurality of clamping jaws 21 for positioning the shoe upper 31. The shoe upper 31 is operatively displaceable relative to the last 32 between an abnormal position (fig. 2) and a normal position (fig. 4), and has a feature 311 which is eliminated. In this embodiment, the feature 311 is a painted double cross symbol. In the abnormal position, the upper 31 is at least partially offset from the last 32, and in the normal position, the upper 31 is fully engaged with the last 32. In this embodiment, the operator operates the clamping jaw 21 of the front upper machine 2 to move the upper 31 to determine whether the upper 31 is located at the normal position or the abnormal position, which may be the upper position identification result of the identification device and the identification method for the upper assembly operation of taiwan patent publication No. 201912109, or the upper position identification result of the upper detection device of M573594U.

The vamp position indicating device comprises a projection unit 4 and a processing unit 5.

In the present embodiment, the projection unit 4 includes a Digital Light Processing (DLP) 41 and an image capturing module 42 installed on the front upper 2.

The projector 41 is used for generating a reference light spot 411 and an indication light spot 412 projected on the upper 31. In this embodiment, the reference spot 411 is a cross. The indication light spot 412 may be one of an up arrow, a down arrow, a left arrow, a right arrow, and a left arrow.

The image capturing module 42 is used for capturing an image 441 of the shoe upper 31 and the last 32.

The processing unit 5 is connected to the projector 41 and the image capturing module 42 through a wired or wireless communication technology, and controls the projector 41 to generate a reference light spot 411 projected on the upper 31 according to a default fixed position, and controls the projector 41 to generate an indication light spot 412 projected on the upper 31 according to the above-mentioned upper position identification result when the upper 31 is located at the abnormal position.

Referring to fig. 5, fig. 2 and fig. 4, the vamp position indication method of the present invention executes the following steps by the processing unit 5:

step 601: according to the default fixed point position, the projector 41 is controlled to generate the reference light spot 411 projected at the fixed point position, so that the operator can align the reference light spot 411 with the characteristic portion 311 of the upper 31, and put the upper 31 on the last 32, so that the reference light spot 411 is overlapped with the characteristic portion 311.

It should be noted that the reference light spot 411 projected at the fixed point can be projected on the upper 31 in advance, and then the last 32 is operated to move to be engaged with the upper 31 relative to the upper 31, or projected on the last 32, and then the upper 31 is operated to move to be engaged with the last 32 relative to the last 32.

Step 602: and judging whether the vamp 31 is positioned at the normal position according to the vamp position identification result, if so, performing step 604, and if not, performing step 603.

It should be noted that the above-mentioned shoe upper position identification result is not limited to the identification device and identification method of shoe upper assembly operation as disclosed in taiwan patent publication No. 201912109, or the shoe upper detection device as disclosed in M573594U, but can be other methods or structures capable of identifying the position of the shoe upper 31.

Step 603: based on the above shoe position recognition result, the projector 41 is controlled to generate the indication light spot 412 projected on the shoe upper 31 to indicate the moved direction of the shoe upper 31, so that the operator can operate the clamping jaw 21 of the toe lasting machine 2 to move the shoe upper 31, and then, the process returns to step 602.

For example, when the shoe upper position recognition result determines that the shoe upper 31 is shifted to the right by an offset amount relative to the last 32, the processing unit 5 controls the projector 41 to generate the indication light spot 412 in the form of a right arrow projected on the shoe upper 31, and at this time, the operator can intuitively operate the clamping jaw 21 of the toe-lasting machine 2 to move the shoe upper 31 to the right during the process of viewing the shoe upper 31 without raising the head.

Step 604: the projector 41 is controlled to stop generating the indication light spot 412. This indicates that the vamp 31 is in the normal position and completely engaged with the last 32, so that the subsequent lasting operation can be performed.

Referring to fig. 6, for example, when the vamp 31 is determined to be deviated by an offset amount to the left relative to the last 32 according to the vamp position recognition result, the processing unit 5 controls the projector 41 to generate an indication light spot 412 in the form of a left arrow projected on the vamp 31, at this time, the operator can intuitively operate the clamping jaw 21 of the front upper 2 to move the vamp 31 to the left, and if the displacement amount is insufficient, the projector 41 will continuously generate the left arrow projected on the vamp 31, and the vamp 31 will disappear after being located at the normal position.

It should be noted that the foregoing indication light spot 412 is not limited to be a right arrow or a left arrow, and in other aspects of the present embodiment, the indication light spot may also be an up arrow as shown in fig. 7, a down arrow as shown in fig. 8, a right arrow as shown in fig. 9, a left arrow as shown in fig. 10, or other symbols, characters, etc. capable of indicating directions.

From the above description, the advantages of the foregoing embodiments can be summarized as follows:

1. the utility model discloses can operate this vamp 31 registrate when this last 32 at the operator, intuitionistic through benchmark facula 411 and the instruction facula 412 on this vamp 31, under the condition that need not raise the head, the position of this vamp 31 of quick adjustment, and then effectively shorten the processing procedure time.

2. Importantly, the reference light spot 411 and the indication light spot 412 can be changed in color and size at will, so that the reference light spot 411 or the indication light spot 412 can be clearly distinguished from the color of the upper 31, or more prominently distinguished, and is easier to identify.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any slight modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments are all within the scope of the technical solution of the present invention.
