Description

Technical Field

[0001] The utility model belongs to the field of intelligent storage and transportation equipment, and specifically relates to a cantilever stacker fork. Background Art

[0002] In the metallurgical industry, the storage and transportation of thin-walled and filamentary steel are often realized in the form of coils. The process has an inner coil, and the inner coil meets industry standards. Taking the transformer industry as an example, after the manufacturer purchases silicon steel coils, it needs to be processed twice. The processing equipment needs to use the inner coil of the coil to cut the coil into coils, and then store them in the beam-type shelves. To store the coils in the beam-type shelves, it is necessary to use the flipping equipment to flip the coils and lay them flat on the pallet, and then use the standard stacker fork to place the pallet on the shelf to complete the warehousing. The opposite is true for outbound delivery. The process is complicated and accessories such as pallets are necessary. Utility Model Content

[0047] The following is an explanation of the implementation of the present invention by means of specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0048] It should be noted that, in the present utility model, the up, down, left and right in the figure are regarded as the up, down, left and right of the cantilever stacker fork described in this specification.

[0049] The exemplary embodiments of the present invention are now introduced with reference to the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to disclose the present invention in detail and completely and to fully convey the scope of the present invention to those skilled in the art. The terms in the exemplary embodiments shown in the accompanying drawings are not intended to limit the present invention. In the accompanying drawings, the same units / elements are marked with the same reference numerals.

[0050] Unless otherwise specified, the terms (including technical terms) used herein have the commonly understood meanings to those skilled in the art. In addition, it is understood that the terms defined in commonly used dictionaries should be understood to have the same meanings as those in the context of the relevant fields, and should not be understood as idealized or overly formal meanings.

[0051] See also Figure 1 This embodiment relates to a cantilever stacker fork, which is suitable for cantilever shelves. The cantilever stacker fork includes a transverse moving device and a rotating device 20. The transverse moving device is suitable for being installed on the stacker loading platform, and the stacker can carry the transverse moving device to achieve lifting and walking; the rotating device 20 at least includes a rotary reducer 23 installed on the transverse moving device, and a cantilever 30 for forking a coil 50 is installed on the rotary reducer 23, that is, the rotating device 20 can slide along the transverse moving device.

[0052] In order to realize the sliding movement of the rotating device 20 along the lateral moving device, in this embodiment, a servo motor is selected to drive the gear rack meshing transmission, and the gear rack drives the slider on the rotating device 20 to move along the slide rail on the lateral moving device.

[0053] Regarding the linear movement of the lateral moving device, other driving modes may also be selected without limitation.

[0054] The cantilever 30 is mounted on the rotary reducer 23 , and the rotary reducer 23 itself can rotate, so the cantilever 30 can achieve linear displacement and the angle of the cantilever 30 can be adjusted by the rotation of the rotary reducer 23 .

[0055] like Figure 2As shown, the coil 50 is sleeved on the cantilever 30, and the cantilever stacker fork is installed on the stacker loading platform as a whole. When the stacker is lifted or moved, the cantilever stacker fork is also lifted or moved accordingly, so as to approach the coil 50 on the cantilever shelf. When facing the coil 50, the rotary reducer 23 adjusts the angle of the cantilever 30 by rotation, and the rotary device 20 slides along the lateral moving device to change the distance from the coil 50, so that the coil is placed on the cantilever 30. This material retrieval process does not require a pallet, and the action of flipping the coil is also omitted.

[0056] Continue reading Figure 1 The cantilever 30 at least includes a cantilever end and a blocking plate 40. The cantilever end is used to fork the coil 50; the blocking plate 40 is installed on the lower surface of the cantilever end through a rotary drive. The blocking plate 40 will be described in detail below:

[0057] In the non-operating state, the rotary drive drives the blocking plate 40 to rotate so that it is parallel to the cantilever. Figure 1 , that is, the blocking plate 40 is hidden under the cantilever; in the working state, the rotary drive drives the blocking plate 40 to rotate so that it is perpendicular to the cantilever (it can also be at other angles), see Figure 2 At this time, the blocking plate 40 is stuck in the inner circle of the coil to prevent the coil 50 from shaking.

[0058] The blocking plate 40 has at least a plate arm. In some embodiments, arc-shaped baffles 41 are respectively provided at both ends of the plate arm to abut against the inner circle of the coil. The arc-shaped baffles 41 can fit the inner circle of the coil more closely, increase the contact area and friction, and the arc-shaped baffles 41 can reduce damage to the inner circle of the coil.

[0059] Since the specifications of the coil 50 are different, the blocking plate 40 can be telescopic, or the arc-shaped blocking bar 41 can be telescopic, or cams are respectively provided at both ends of the plate arm to adapt to the inner circle of the coil with different diameters.

[0060] A distance meter 21 is installed on the rotary device 20 , and the distance meter 21 is electrically connected to the PLC controller.

[0061] The rangefinder 21 can select a laser rangefinder to detect the distance L from the coil 50 on the cantilever shelf to the rotating device 20. The rangefinder 21 transmits the distance L to the PLC controller. The PLC controller calculates and outputs the sliding value of the rotating device 20 along the lateral moving device, and controls the rotating device 20 to slide according to the value to approach the coil 50 on the cantilever shelf.

[0062] Specifically, the lateral moving device includes a base 10 and a slide 22. The slide 22 is slidably mounted on the base 10, and the rotary reducer 23 is mounted on the slide 22. A rotary angle photoelectric switch 24 is mounted on the slide 22 to limit the rotary angle of the rotary reducer 23, and the rotary angle photoelectric switch 24 is electrically connected to the PLC controller.

[0063] When the cantilever stacker fork as a whole approaches the coil 50 on the cantilever shelf, the angle of the cantilever 30 needs to be adjusted to achieve the best distance to fork the coil 50. At this time, the rotary reducer 23 can drive the cantilever 30 to rotate, and the rotation angle photoelectric switch 24 can limit the rotation angle.

[0064] Combination Figure 1 and Figure 3 An elastic signal-transmitting plate 31 is installed at the cantilever end of the cantilever 30, and the elastic signal-transmitting plate 31 blocks the end surface of the cantilever, and a gap is left between the two, that is, in a normal state, the elastic signal-transmitting plate 31 does not contact the end surface of the cantilever.

[0065] A first photoelectric switch is installed on the end face of the cantilever to detect the distance from the elastic signaling plate 31. The first photoelectric switch is electrically connected to the PLC controller. Specifically, the distance between the elastic signaling plate 31 and the end face of the cantilever is preset as P, and the signaling distance set by the first photoelectric switch is Q. The P value must be greater than the Q value. If the coil 50 on the shelf squeezes the elastic signaling plate 31, the P value decreases. When the P value is less than the Q value, the first photoelectric switch is triggered and the signal is sent to the PLC controller. The PLC controller can make a decision: remind the staff to handle, issue an alarm, or even make an emergency stop.

[0066] In some embodiments, two first photoelectric switches are installed on the end surface of the cantilever to improve the detection sensitivity.

[0067] Combination Figure 3 and Figure 4 The cantilever stacker fork also includes a spring assembly 60 installed at the cantilever end, a second photoelectric switch and a signaling rod 70, the signaling rod 70 is connected to the spring assembly 60, the spring assembly 60 is connected to (contact or non-contact) the second photoelectric switch, and the second photoelectric switch is electrically connected to the PLC controller.

[0068] Specifically, a groove is hollowed out on the upper surface of the cantilever end, the groove is parallel to the cantilever, and the signaling rod 70 is accommodated in the groove. In some embodiments, the end of the signaling rod 70 away from the end surface of the cantilever is hinged in the groove, and the other end of the signaling rod 70 is connected to the spring assembly 60.

[0069] In other embodiments, a support plate may be fastened to the upper surface of the cantilever and a groove may be machined on the support plate.

[0070] For spring assembly 60, see Figure 4, it includes a spring seat 61, a top screw 62, a pin 63, and a spring 64. The spring seat 61 is installed on the end surface of the cantilever, and the spring seat 61 has at least a through hole, the top screw 62 is sleeved in the through hole, the pin 63 penetrates the top screw 62 from bottom to top and then extends out of the through hole, one end of the signaling rod 70 is connected to the top of the pin 63, and the other end of the signaling rod 70 is hinged to the upper surface of the cantilever of the cantilever 30; the spring 64 is sleeved on the pin 63 to be in an extended state or a compressed state with the movement of the pin 63.

[0071] The second photoelectric switch is installed on the end surface of the cantilever and is directly opposite to the bottom surface of the pin shaft 63 .

[0072] When the coil 50 is not forked, the junction of the signal rod 70 and the pin 63 is slightly higher than the upper surface of the cantilever end. When the coil 50 is sleeved on the cantilever 30, the weight of the cantilever 30 squeezes the signal rod 70, and the pin 63 moves downward. The second photoelectric switch detects that the distance between it and the pin 63 has changed, triggering the fork to have material signal, that is, sending a signal to the PLC controller, and the PLC controller then controls the cantilever stacker fork to take action.

[0073] The triggering principle of the second photoelectric switch can refer to the first photoelectric switch.

[0074] Continue reading Figure 4 The pin 63 is divided into a large diameter section and a small diameter section. Figure 4 In the figure, the upper part of the pin 63 is a large diameter section, and the lower part is a small diameter section. The spring 64 is sleeved on the small diameter section and is located in the annular cavity formed by the large diameter section and the top wire 62. The top wire 62 is sleeved on the small diameter section and is located below the spring 64.

[0075] A through hole is bored in the large diameter section of the pin shaft 63 , and its function is to connect the spring seat 61 and the pin shaft 63 with screws, while also ensuring the axial movement of the pin shaft 63 .

[0076] A third photoelectric switch is installed at the cantilever end of the cantilever 30, the third photoelectric switch faces the upper surface of the cantilever end and is electrically connected to the PLC controller. When there are multiple rolls 50 on the cantilever shelf, the third photoelectric switch is used to send a signal when taking a single roll 50.

[0077] About the working process of multiple coils 50 on cantilever rack:

[0078] There are multiple coils 50 on the preset cantilever shelf, and there is a distance of about 50mm between the coils 50. The fork needs to take out the outermost coil. At this time, the sliding distance of the fork must be accurate to prevent the fork from sliding too much, causing the second coil to be dragged and causing a dangerous incident. The sliding distance can be calculated based on the data of the rangefinder 21 and the inventory coil data in the system. Of course, this has extremely high requirements for system data and low reliability. Here, detection feedback is added, and the third photoelectric switch can provide real-time feedback. When the fork slips, the third photoelectric switch will pass through the inner diameter of the coil to form a light-dark-light signal change, so that the sliding of the fork stops. The aforementioned fork refers to the cantilever 30.

[0079] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present invention, and in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present invention.
