Detailed Description

Referring now to the drawings, illustrative versions of the disclosed apparatus will be described in detail. Although the drawings are provided to present some embodiments of the invention, the drawings are not necessarily to scale of particular embodiments, and certain features may be exaggerated, removed, or partially sectioned to better illustrate and explain the present disclosure. The position of some components in the drawings can be adjusted according to actual requirements on the premise of not influencing the technical effect.

Certain directional terms used hereinafter to describe the accompanying drawings will be understood to have their normal meanings and to refer to those directions as they normally relate to when viewing the drawings. Unless otherwise indicated, the directional terms described herein are generally in accordance with conventional directions as understood by those skilled in the art. Where "longitudinal" denotes the length direction of the conveyor indicated by "X" in fig. 1, "transverse" denotes the width direction of the conveyor indicated by "Y" in fig. 1, and "vertical" denotes the height direction of the entire test labeling apparatus indicated by "Z" in fig. 1, where the fuses are to be conveyed in the longitudinal direction but placed on the conveyor extending transversely. In addition, label tape is herein referred to as a generic term for labels and backing paper, wherein one side of the label is glued to the backing paper and the label tape is stored in a roll, typically after not or after use.

Fig. 1 and 2 show perspective views of a test labeling apparatus according to the present invention from different angles. The test labeling equipment is mainly designed for a fuse and aims to firstly perform resistance measurement on the fuse, then determine whether to label the fuse according to a measurement result and correspondingly perform a subsequent labeling process. The fuse mainly comprises a fusion tube and two outer caps arranged at two ends of the fusion tube, and each outer cap is connected with a contact knife. Labeling the fuse means that a label is attached to the entire or a part of the outer peripheral wall of the fuse tube according to the size of the label. Of course, the test labeling device according to the present invention is not limited to be applied to fuses, and other components similar to the operation principle and the shape of the fuses may be tested and labeled by the test labeling device according to the present invention.

The invention relates to a testing and labeling device which mainly comprises a resistance detection station 1, a rotating station 2, a conveying device 6, a label feeding device 3, a label taking device 4, a sorting station 7 and the like. The fuses are first resistance measured at the resistance testing station 1, the resistance testing station 1 sends the measurement results to a controller (not shown), and subsequently the transfer device 6 transfers the fuses to the rotating station 2, which rotating station 2 will grip at least one end of the fuses, for example one or two outer caps, of course one or two contact knives. If the measured value of the electrical resistance meets the criteria, the label feeder 3 will supply a label that has been peeled from its backing paper under the control of the controller, and the label remover 4 will pick up the label from the label feeder 3 and cause it to abut at least partially against the outer peripheral surface of the melting tube at the rotary station 2. Next, the rotation station 2 drives the fuse to rotate, and the label taking and affixing device 4 abuts against the label glued on the fusion tube to press the entire label against the outer peripheral surface of the fusion tube as the fuse rotates. Downstream of the rotary station 2, a sorting station 7 is arranged, which comprises at least two sorting channels 71 for passing respectively the acceptable products and the unacceptable products. If the resistance detection does not meet the criteria, no subsequent labelling step will be performed and the controller will control the sorting station 7 to traverse to bring the faulty fuse into the corresponding sorting channel 71.

Specifically, as shown in fig. 3, the electrical resistance testing station 1 is configured to include an electrical resistance meter (not shown), two sets of test chucks 11 arranged oppositely in a lateral direction, each set of test chucks 11 being capable of serving as two measuring ends of the electrical resistance meter, and a second vertical displacement mechanism 12 that drives the test chucks 11 to move up and down in a vertical direction. When the resistance detection is not performed, the detection chuck 11 is in the raised position. When the fuse is conveyed to or directly placed below the vertical direction of the detection chuck 11, the second vertical displacement mechanism 12 drives the detection chuck 11 to descend, each group of detection chucks 11 respectively clamps the peripheral wall of one outer cap to position the fuse and electrically connect with the outer cap, and therefore the fuse and the resistance meter form a closed loop to realize resistance measurement of the fuse. When the measurement is completed, the inspection jaw 11 is raised again by the second vertical displacement mechanism 12 to release the fuse, allowing it to be taken out or transferred to the next station. It will of course be appreciated by those skilled in the art that the detection cartridge 11 is not limited to the form of the peripheral wall clamped to the outer cap shown in fig. 3, for example the detection cartridge 11 may be designed to be pressed laterally against the end faces of the two end caps facing away from each other, respectively, which also enables an electrical connection to be made with the two end caps.

Fig. 4 shows a preferred construction of the rotary station 2. The rotary station 2 is used mainly in conjunction with a label picking and labeling device 4, described in detail below, for positioning, clamping and rotationally driving the fuses. Specifically, the rotation station 2 is configured to include two rotation limiting seats 22 arranged laterally opposite to each other and a rotation limiting member 21 arranged vertically above each rotation limiting seat 22, and an arc-shaped concave portion conforming to the outer peripheral wall of the outer cap is opened on an end surface of the rotation limiting member 21 facing the rotation limiting seats 22. The rotation limiting member 21 presses the outer peripheral walls of the two outer caps against the rotation limiting seat 22 by means of the arc-shaped concave portion. The rotation station 2 further comprises a first telescopic mechanism 24 and a rotation drive mechanism 23. The first telescopic mechanism 24 is designed to drive the rotation limiting member 21 to rotate by means of the driving link to be raised and lowered with respect to the rotation limiting seat 22. When the rotation limiting member 21 is lifted with respect to the rotation limiting seat 22, the fuse can be put in or removed. When the rotation limiting member 21 is dropped with respect to the rotation limiting seat 22, the fuse is fixed in position with respect to the entire rotation station 2. The rotation driving mechanism 23 is designed to drive the rotation limiting seat 22 and the rotation limiting member 21 to rotate synchronously, so as to drive the fuse clamped between the two to rotate, and the specific rotation direction can be set as required.

Of course, it will be understood by those skilled in the art that other types of arrangements may be employed for the rotation station to perform the gripping and rotating functions for the fuses. For example, the rotary station can use two jaws which can be opened and closed to grip and release a contact blade of, for example, a fuse and thereby rotate the entire fuse. The rotation station may also take the form of two parts extending from the lateral ends and being depressed beyond the ends of the end caps.

Fig. 5 shows a perspective view of the label feeding device 3, wherein the label feeding device 3 is preferably arranged on a lateral side of the conveyor 6, which is described in more detail below. The label feeding device 3 mainly includes a mounting plate 35 extending generally vertically, and a label tape unwinding mechanism 32, a tension and guide mechanism 33, a peeling mechanism 31, and a label tape winding mechanism 34 provided on the mounting plate 35. Wherein the label tape unwinding mechanism 32 comprises an unwinding motor and an unwinding shaft on which unused label tape will be wound in roll form and provide a continuous label tape as the unwinding shaft rotates. The tensioning and guiding mechanism 33 basically comprises a tensioning rod 331 coupled to a tensioning shaft, not shown, an upper limit sensor (not shown), a lower limit sensor (not shown) and a number of guiding shafts 332 around which the label tape will be wound as required through the various components of the tensioning and guiding mechanism 33. The upper limit sensor and the lower limit sensor are used to sense the uppermost position and the lowermost position of the tension lever 331, respectively. When the movement of the tension rod 331 falls within the sensing range of the upper limit sensor, for example, rotating in the counterclockwise direction, the unwinding motor stops rotating; when the tension rod 331 moves, for example, in a clockwise direction, falling within the sensing range of the lower limit sensor, the unwind motor starts rotating, and so on. This ensures that the label tape is always under tension and cooperates with the beat-to-beat operation of the peeling mechanism 31, which will be described below.

The peeling mechanism 31 has a peeling plate 311 with a peeling end 312 for separating the label and the liner, which is shown in more detail in fig. 6. The label tape will first travel along the upper end face of the peeling plate 311 by the tensioning and guiding mechanism 33 described above, and after passing around the peeling end 312 the labels will be separated from the base paper which will be wound around the lower end face of the peeling plate 311 and retracted by the label tape take-up mechanism 34. The peeling end 312 may be designed, for example, as a sharp edge, and as the label strip passes the peeling end 312, one end of the label will first break away from the substrate, and the substrate will continue to travel under the action of the label strip take-up mechanism 34, with the label being progressively separated from the substrate. The peeling mechanism 31 of the above-described configuration is particularly suitable for hard labels, but for soft labels or labels having a high bonding strength with the base paper, there is a risk that the labels will not be smoothly separated from the base paper, that is, the labels will be finally taken into the take-up mechanism as the base paper continues to travel. Alternatively, the peel tip may not be sharp, for example, a peel blade may be provided in front of the peel plate, but the blade must enter smoothly between the label and the base paper to be effective.

Thus, the present invention is further provided with a peeling lever 313 vertically below the peeling plate 311, the liner separated from the label will be wound around the peeling lever 313 to be moved by the peeling lever 313, while the peeling plate 311 and the peeling lever 313 are designed to be able to synchronously perform a rhythmic movement in a first direction and a second direction opposite to each other. The first direction is chosen to be parallel to the direction of travel of the labels on the upper surface of the stripper plate 311 and the second direction is the direction opposite to the direction of travel of the labels on the upper surface of the stripper plate 311. At the time of label stripping, the label upper surface can be sucked by means of the suction head 41, which will be described in detail below, when the label to be stripped will reach the stripping end 312, which step can be understood as keeping the label to be stripped still. At the same time, the peeling plate 311 and the peeling lever 313 are moved synchronously toward the second direction, which means that the peeling plate 311 is withdrawn from below the label to be peeled to make the peeling space, and at the same time, the peeling lever 313 drives the base paper positioned at the position where the peeling plate 311 makes the space to be peeled away from the lower surface of the held label to be peeled. After the label is successfully peeled, the peel plate 311 and peel lever 313 move back to the home position in the first direction for the next label to continue to the peel position. The synchronized rhythmic motion of peel plate 311 and peel lever 313 may provide a momentary force for tearing the base paper off the lower surface of the label, which is particularly effective for soft labels. The stripping end is laterally aligned with the indexing mechanism when the stripping plate travels in a first direction to a maximum stroke.

The label tape winding mechanism 34 mainly includes an elastic pressing member 341 and a winding shaft 342 as shown in fig. 5. It is also preferable that a guide shaft through which the base paper is wound after being wound around the peeling lever 313 is further disposed below the peeling plate 311. The elastic pressing member 341 mainly includes a steering roller and an elastic pressing member, and the elastic pressing member presses the base paper against the surface of the steering roller.

Fig. 7 shows a schematic view of a preferred configuration of the labeling device 4, which mainly comprises a labeling mechanism and a labeling mechanism. Wherein the label picking mechanism is designed to pick up a label from the label feeder 3 and to locally abut the label against the outer circumferential surface of the melt tube at the rotary station 2. Specifically, the index mechanism is configured to include a suction head 41, a first vertical displacement mechanism 42, and a first lateral displacement mechanism 43, and the suction head 41 is movable vertically and laterally by the drive of the first vertical displacement mechanism 42 and the first lateral displacement mechanism 43. As shown in fig. 8, the suction head 41 includes a label suction member 44 having at least one suction hole (not shown) opened on a lower end surface thereof, the suction hole being in fluid communication with a negative pressure device (not shown) to generate a negative pressure in the suction hole to suck the label. The stripping end 312 is preferably aligned transversely with the suction head 41 when the stripping plate 311 travels in the first direction to a maximum stroke, whereby the suction head 41 only has to perform a transverse movement and a vertical movement for carrying the label, no additional movement in the longitudinal direction is required. It will be understood by those skilled in the art that the suction head 41 may be provided with a longitudinal displacement mechanism so as to be more flexible in sucking the label, subject to the restriction of installation space and the like.

As described above, at the start of peeling, the suction head 41 moves vertically above the label to be peeled to suck the label, and when the label has been peeled, the suction head 41 is displaced laterally with the label vertically above the fusion tube at the rotating station 2, placing the label on the outer peripheral wall of the fusion tube. But the label is less bonded to the fusion tube at this time and is easily detached from the fusion tube, whereby it is possible to further lower the suction head 41 in the vertical direction until the label is brought into close contact with the outer peripheral wall of the fusion tube. Preferably, as shown in fig. 8, a pair of claw members 45 may be further provided on both sides of the label holding member 44 facing in the longitudinal direction, and the pair of claw members 45 can be rotated toward the label holding member 44 to perform the closing and opening actions. The claw 45 can press the outer circumferential surface of the fusion tube when it is closed above the fusion tube, thereby pre-pressing a part of the label to the outer circumferential surface of the fusion tube, which has the effect of pre-positioning, preventing the label from falling off when the rotational movement is performed next.

The labeling mechanism comprises a roller 46 and a second telescopic mechanism 47 for driving the roller 46 towards or away from the rotary station 2. When the roller 46 is retracted, it does not interfere with the normal operation at the rotary station 2. When the roller 46 is extended, it will abut against the outer circumferential surface of the melt tube at the rotary station 2, thereby conforming the entire label to the outer circumferential wall of the melt tube as the melt tube rotates.

It follows that the labelling action according to the invention is performed by cooperation of the label taking mechanism and the labelling mechanism. The alternate operation of the two components improves the operation efficiency of the whole device, improves the consistency of labeling quality and prevents the label from being separated from the product undesirably.

The label taking structure may alternatively be performed by only one mechanism, for example having only one rolling member, the above-mentioned peeling end being arranged vertically above the melt tube at the rotation station, the rolling member being pressed vertically by a pressure drop directly against the label on the melt tube after the movement of the peeling plate in the second direction and subsequently performing the rotational movement. This is inefficient and it is difficult to ensure that the label is already engaged with the peripheral wall of the cartridge before rolling.

As described above, the label peeling process of the label feeding device 3 employs a beat-to-beat operation mode, and in order to continuously perform resistance detection and labeling for a plurality of fuses, the entire device preferably also employs a beat-to-beat operation mode. However, since the time for the resistance testing is significantly shorter than the operating time of the labeling device 4, a buffer station 5 is preferably provided between the resistance testing station 1 and the rotary station 2 in order to increase the operating efficiency.

The buffer station 5 is configured as shown in fig. 9 to include a positioning ram 51 and a third vertical displacement mechanism 52 that drives the positioning ram 51 to be vertically displaced. The locating ram 51 may also include an arcuate recess into which the locating ram 51 descends to accommodate the fuse therein to hold it in place as it is transferred to the buffer station 5.

Fig. 10-12 show schematic views of the transfer device 6. The conveyor 6 is configured to include a feeding mechanism 61 and a transfer mechanism 63. The feeding mechanism 61 may be in a conveyor belt mode and may be angled with respect to the horizontal as shown in figure 10 to allow the fuse to slide downward under gravity. The transfer mechanism 63 is disposed downstream of the feed mechanism 61 and extends in the longitudinal direction. In order to ensure that only one fuse enters the transfer mechanism 63 at a time when a plurality of fuses are continuously processed, a material dividing station 62 is provided between the feeding mechanism 61 and the transfer mechanism 63.

The material dispensing station 62 preferably includes a resilient stop 621 and a hold-down assembly 622 as shown in FIG. 11. The hold-down assembly 622 includes a hold-down member and a hold-down limit for limiting a lowering distance of the hold-down member. The hold-down member is lowered from vertically above and pressed against the fuse to be processed to align the fuse and restrict further longitudinal displacement thereof. The resilient stop 621 is supported below by a spring that is disposed in and projects vertically upwardly from a slot opening in the bottom surface of the dispensing station 62 to stop a fuse that will enter the transfer mechanism 63. When a fuse that is going to enter the transfer mechanism 63 has a tendency to move longitudinally under the action of an external force, it will press against the resilient catch 621, the spring supporting the resilient catch 621 being compressed and possibly tilting the resilient catch 621 to partially enter the slot, whereby the fuse passes over the resilient catch 621 into the transfer mechanism 63. After the fuse passes over the resilient catch 621, the resilient catch 621 returns to its original position under the action of the spring, catching the next fuse.

The transfer mechanism 63 is configured as shown in fig. 11 and 12 to comprise a carrying platform 631, at least one support 632, a fourth vertical displacement mechanism 633 and a first longitudinal displacement mechanism 634, wherein the number of supports 632 is associated with the number of corresponding stations in the entire plant. For example, when five stations, i.e., the dividing station 62, the resistance detecting station 1, the buffer station 5, the rotating station 2, and the sorting station 7 (described in detail below) are employed from upstream to downstream herein, it is necessary to employ corresponding four carriers 632 to transfer the fuses respectively from the upstream station to the downstream station. Specifically, the carrying platform 631 extends in a longitudinal direction and is provided with a vertically through material conveying channel 635 in the longitudinal direction. The support 632 is longitudinally displaceable within the transfer tunnel 635 by actuation of a first longitudinal displacement mechanism 634, each station being disposed at a corresponding position vertically above the transfer tunnel 635. Wherein the supporting member 632 is provided with a lower concave portion for accommodating the fuse. The fourth vertical displacement mechanism 633 is used for driving the supporting member 632 to move vertically in the material conveying channel 635, and when the supporting member 632 ascends, the supporting member can support the fuse; when the support 632 is lowered, the fuse will bridge on the support platform 631 by means of its end cap or its contact blade, thereby releasing the fuse. During operation, the four supporting members 632 are respectively and correspondingly located below the distributing station 62, the resistance detecting station 1, the buffer station 5 and the rotating station 2, the supporting members 632 vertically lift up the fuses at the corresponding stations, then the supporting members 632 longitudinally shift towards the direction of the next station, namely, the supporting members are respectively moved to the positions below the resistance detecting station 1, the buffer station 5, the rotating station 2 and the sorting station 7, the supporting members 632 descend to enable the fuses to fall onto the supporting platform, and finally the supporting members 632 reset to the upstream station. The synchronous shifting of the fuses at a plurality of stations is realized by repeatedly executing the steps.

In addition, the above only exemplifies preferable examples of the transfer device, but the structure of the transfer device is by no means limited thereto. For example, the entire conveyor may take the form of a belt, with sensing scans or the like to determine where the fuses have reached the various stations. Or 4 corresponding robots may be provided, respectively, each robot corresponding to a fuse transfer between an upstream station and a downstream station.

Fig. 13 shows a schematic view of a sorting apparatus. Since the resistance testing station 1 described above will send the measurements to the controller, the controller will control the movement of the sorting apparatus to separate the acceptable and unacceptable products. Specifically, the sorting apparatus includes at least two sorting channels 71 arranged in the lateral direction and a second lateral shift mechanism 72 that drives the sorting channels 71 to shift in the lateral direction under the control of the controller. Wherein different sort lanes 71 correspond to different collection receptacles 73. When, for example, a fuse that has not been labeled due to a defective resistance test occurs, the second lateral shift mechanism 72 is actuated to cause the fuse conveyed from the rotary station 2 to enter a passage different from the defective fuse, thereby entering the separate collection container 73. The method does not need to interrupt the normal operation process of the whole equipment, and even if the products with unqualified resistance are produced, the products only need to be continuously transmitted according to the set program without manual intervention or shutdown treatment.

According to the test labeling equipment for the fuse, the existing situation of manual operation in the existing production is changed, the product quality is guaranteed, the labeling consistency is guaranteed, the production speed is increased, and the production efficiency is improved.
