[0024] Refer to the accompanying drawings. The present invention provides a device for transferring labels, including a label storage mechanism 100, a label transfer mechanism and a zoom label arrangement mechanism 300. The label transfer mechanism includes a first label transfer mechanism 200 and a second label transfer mechanism 400, which are respectively located upstream and downstream of the zoom label arrangement mechanism 300 in the direction of label movement. The first label transfer mechanism is provided with a plurality of structures 201 for absorbing labels, the second label transfer mechanism is provided with a plurality of label jigs 401 capable of absorbing labels and capable of being inserted into a mold, the zoom label arrangement mechanism 300 is provided with a plurality of label pre-forming structures 301 capable of absorbing labels, and the label storage mechanism 100 has a plurality of label storage positions 101 and outlets 102 thereof.

[0025] The label storage mechanism is distributed on both sides and is located at the upper part of the device, and its two side parts are respectively represented by the variations 100a and 100b in the attached figure; the first label transfer mechanism corresponds to the label storage mechanism and is also distributed on both sides, and its two side parts are respectively represented by the variations 200a and 200b in the attached figure.

[0026] The label storage position 101 can be a rack for storing label stacks. The label storage positions 101 on both sides of the label storage mechanism 100 can be equal or unequal in number. The number and arrangement spacing of the label absorbing structures 201 on both sides of the first label transfer mechanism correspond to the number and arrangement spacing of the label storage positions 101 on both sides of the label storage mechanism 100.

[0027] The zoom label arrangement mechanism 300 is arranged below the first label transfer mechanism 200 and the label storage mechanism 100. The two side parts 200a and 200b of the first label transfer mechanism can respectively move between the two side parts 100a and 100b of the label storage mechanism and the zoom label arrangement mechanism 300, respectively dock with the label storage mechanism part on the same side to take the front label 500 of the label stack 50 in the label storage position 101, and then transport it to dock with the zoom label arrangement mechanism 300 to transfer the label. The second label transfer mechanism 400 can dock with the zoom label arrangement mechanism 300 to extract the preformed label 500a of the matching jig 401 on the label preforming structure 301 in the zoom label arrangement mechanism 300 through its label jig 401, and transfer it to the mold 600. A plurality of mold cavities are arranged in the mold 600, and the arrangement spacing of the label jig 401 on the second label transfer mechanism 400 is the same as the arrangement spacing of the mold cavities in the mold 600.

[0028] The two side parts 100a, 100b of the label storage mechanism 100 are arranged in an "eight" shape and the label storage positions 101 are all arranged in an inclined manner. The label outlet 102 of the label storage mechanism is inclined toward the inner and lower side, so that the two side parts 100a, 100b of the label storage mechanism are respectively located at the upper and oblique outer sides or slightly above the outer sides of the two side parts 200a, 200b of the first label transfer mechanism, which can not only utilize gravity for material discharge, but also reduce the movement stroke of the first label transfer mechanism to improve efficiency.

[0029] Through the above-mentioned movement route setting, the position of the zoom label arrangement mechanism 300 itself does not move, and can be fixedly installed, without translation or lifting. The structure is simple, which can greatly reduce the power requirements of the device and improve efficiency. The label preforming structure 301 in the zoom label arrangement mechanism 300 has a receiving work position and an output work position. Figure 4 , Figure 4 In the left and middle sub-figures, the label preforming structure 301 at the receiving work position is divided into left and right parts, and the spacing and number of the left and right parts are equal to the spacing and number of the label absorbing structures 201 on both sides of the first label transfer mechanism. The two can be aligned and docked to transfer the labels. Figure 4 In the right sub-figure in , the number and spacing of the label preforming structures 301 at the output work position are the same as the arrangement spacing and number of the label fixtures 401 on the second label transfer mechanism 400, and the two can be aligned and docked to transfer the labels.

[0030] The zoomable label arrangement mechanism is provided with a label preforming structure moving mechanism, so that the label preforming structure 301 can move between the receiving work position and the output work position. The moving mechanism can be realized by a guide groove, a limiting structure and a conveying mechanism.

[0031] Each side portion of the first label transfer mechanism is rotatably mounted, and each label suction structure 201 of each side portion can be coaxially rotatably mounted, wherein the reference numeral 202 is the axis, and the label suction structure can be connected to an electric cylinder or an air cylinder 203 to be retractable, and then connected to the axis 202 through the electric cylinder or the air cylinder 203 and its mounting frame 204. When rotating to align with the outlet 102 of the label storage mechanism 100, the air cylinder 203 moves to extend each label suction structure 201 and dock, suck the label, and after the label is handed over, the air cylinder moves and retracts, and when rotating to vertically downwardly align with the label preforming structure 301 in the receiving working position, the air cylinder 203 moves to extend each label suction structure 201 and dock, and the label is handed over to the label preforming structure 301 with suction function, and after the label is handed over, the air cylinder moves and retracts, and then rotates back to align with the outlet 102, and the cycle is repeated.

[0032] There is an intermediate space 700 between the first label transfer mechanism and the label storage mechanism side part 100a, 200a and the first label transfer mechanism and the label storage mechanism side part 100b, 20b, and the intermediate space serves as the setting and working space of the second label transfer mechanism, so that the whole device is combined into a very integrated and space-efficient whole.

[0033] For the grooved intermediate space 700 between the one side part 100a, 200a of the first label transfer mechanism and the label storage mechanism and the other side part 100b, 200b of the first label transfer mechanism and the label storage mechanism, lifting work can be performed in this space to raise and lower the label fixture 401 of the second label transfer mechanism. At the same time, the channel can be used for longitudinal movement to move the label out of the device and put it into the mold 600. The output working position of the label preforming structure 301 is exactly at the bottom of the space. For this, the second label transfer mechanism is provided with a lifting mechanism 402 of the label fixture and a mechanism 403 for back and forth transfer along the length direction of the intermediate space. The lifting mechanism 402 can adopt a cylinder and a corresponding lifting guide mechanism, and the mechanism 403 can adopt a synchronous belt mechanism and a corresponding translation guide mechanism.

[0034] In summary, the above device can complete the label transfer movement of the present invention, which specifically includes the following steps:

[0035] S1: The first label transfer mechanisms on both sides respectively absorb the first side of the corresponding bottom label in the label storage mechanisms on both sides

[0036] S2: The first label transfer mechanisms on both sides suck the first side of the label and rotate downward to place the label into the label preforming structure 301 corresponding to the receiving working position of the zoom label arrangement mechanism. The first label transfer mechanisms on both sides can rotate synchronously and move back and forth between the corresponding label storage mechanisms 100 and the zoom label arrangement mechanism 300 on both sides.

[0037] S3: The first label transfer mechanisms on both sides rotate upward and return to the corresponding position of the label storage mechanism

[0038] S4: The scaling label arrangement mechanism rearranges the positions of the received labels by moving the label preforming structure 301, and during the position rearrangement process, the spacing between the labels is reduced to be consistent with the spacing of the mold cavities on the mold. The arrangement method corresponds one-to-one to the arrangement of the fixtures of the second label transfer mechanism, and the labels are concentrated to the output work position in the middle of the scaling label arrangement mechanism and are located at the bottom of the middle space between the two sides.

[0039] S5: The second label transfer mechanism moves to a position corresponding to the label preforming structure 301 at the output working position, descends and sucks the first surface of the label, lifts and then moves the label out along the middle space 700, and transports the label to the mold cavity of the mold.

[0040] S3 and S4 can be performed simultaneously, and the time of each step can overlap.

[0041] The above description is only a specific embodiment of the present invention, but the structural features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the protection scope of the present invention.
