Description

Technical area

[0001] The utility model relates to the field of film reel packaging technology and in particular concerns a vertical palletizing device for film reels. Technical background

[0002] To ensure proper dust-proof storage of the film reels and to prevent surface damage during transport, the film reels must usually be packaged before transport. The film reels must be rolled up and stacked on a pallet for storage. When the number of film reels on the pallet reaches the specified quantity, the pallet is picked up by a forklift and transported to the truck.

[0003] In order to improve the degree of automated production, the company now uses the palletizing device to vertically stack film reels. The stacking device usually places two rows of pallets, and an aisle is formed between the two rows of pallets. The palletizing gripper in the palletizing device grips the film reel and moves in the aisle. When the film reel is moved to the side of the set pallet, the film reel is placed on the pallet. However, if the palletizing gripper grips the film reels sideways, the gripper may have unstable gripping force and the film reel may fall to the aisle floor, which not only causes the film reel to be placed incorrectly, but also may affect the subsequent movement and handling of other film reels by the palletizing gripper. It is difficult for staff to find and handle the film reels in time.In addition, there is also the possibility of damage due to collision with the palletizing gripper if pedestrians or objects are placed on the floor in the passageway during normal operation of the palletizing device.

Specific embodiments

[0018] The utility model provides a vertical palletizing device for film reels. To clarify the technical problems, technical solutions, and advantageous effects to be solved by the utility model, the utility model is described in more detail below in combination with the attached drawings and embodiments. It should be understood that the specific embodiments described herein serve only to explain the utility model and do not limit the utility model.

[0019] In this application, the X-axis is the direction extending back and forth, that is, the transverse direction, the Y-axis is the direction extending left and right, that is, the longitudinal direction, and the Z-axis is the direction extending up and down, that is, the vertical direction.

[0020] It is based on the Fig. 1 to Fig. 3. A vertical palletizing device for film reels, comprising two symmetrically arranged uprights 1, a cross slide 2 arranged above the two uprights 1 and slidably mounted on the two uprights 1, front and rear drive assemblies 3 for driving the reciprocating movements of the cross slide 2, a longitudinal slide 4 arranged slidably on the cross slide 2, left and right drive assemblies 5 for driving the left and right movements of the cross slide 4, a lift 6 arranged below the longitudinal slide 4, and a pallet gripper 7 driven up and down by the lift 6, wherein a palletizing area 8 is formed between the two uprights 1, the palletizing area 8 comprising two rows of pallet placement areas 81 and a passage 82 between the two rows of pallet placement areas 81, the pallet placement areas 81 and passages 82 all extending in the transverse direction,wherein a plurality of transversely spaced pallets 83 are placed in each row of pallet placement areas 81, wherein a near area within the passage 82 is detected by a first safety light barrier 91 for the presence of objects; wherein the palletizing gripper 7 is used to grip the film reel as well as to vertically place the film reel on the pallet 83; wherein a warning indicator 93 is provided on the stand 1, wherein the warning indicator 93, the first safety light barrier 91, the front and rear drive assemblies 3, the left and right drive assemblies 5, the elevator 6, and the palletizing gripper 7 are all controlled by the film reel packaging control system.

[0021] In fact, the front area of ​​the stand 1 is equipped with a turning machine capable of turning the packaged and horizontally positioned film reel into an upright state, and the film reel to be palletized is located at the film reel gripping point. After the vertical film reel palletizer starts palletizing, the front and rear drive assemblies 3 and the left and right drive assemblies 5 cooperate to drive the cross slide 2 and the longitudinal slide 4 to slide, so that the palletizing gripper 7 is moved over the film reel. The elevator 6 drives the palletizing gripper 7 to lower, causing the palletizing gripper 7 to extend into the paper roll core of the film reel and clamp the film reel to grip the film reel.The elevator 6 then raises the palletizing gripper 7, and then the palletizing gripper 7 grasps the film reel and runs laterally through the passage 82 until the film reel moves to the side of the set pallet 83, and then moves longitudinally to the top of the pallet 83. The elevator 6 drives the palletizing gripper 7 to lower and finally places the film reel in the pallet 83.

[0022] When pedestrians break into the passage 82, objects are placed on the passage 82 and are not cleared in time, and the palletizing gripper 7 releases the film reel during handling, so that the film reel falls to the ground, the light emitted by the transmitter of the first safety light barrier 91 is blocked and cannot be received by the receiver of the first safety light barrier 91, so that the first safety light barrier 91 returns a signal to the control system of the film reel packaging, and the control system of the film reel packaging immediately controls the vertical palletizing device of the film reel to stop to avoid collisions caused by the continued movement of the palletizing gripper 7.At the same time, the film reel packaging control system also controls the alarm indicator 93 to remind staff to solve problems in time to ensure the safety of staff and equipment in the work process.

[0023] In particular, the warning device 93 may be a warning device 93 capable of issuing audible and visual warnings simultaneously and immediately attracting people's attention to ensure that the warning message is communicated quickly.

[0024] In particular, the legs 11 of the two stands 1 are connected by a plurality of longitudinally extending struts 13, wherein the generator of the first safety light barrier 91 is arranged on one of the struts 13 and the receptacle of the first safety light barrier 91 is arranged on the strut 13 adjacent to this strut 13. This adjustment allows the first safety light barrier 91 to be set up using the strut 13, and the first safety light barrier 91 can fine-tune its height on the strut 13 to ensure that the transmitter and receiver of the first safety light barrier 91 form an effective contrast detection device. Compared to installing the first safety light barrier 91 directly on the floor, it has the advantages of adjustable position and reduced dust pollution.

[0025] Since the detection length of the first safety light barrier 91 is limited, three struts 13 are provided to improve the detection accuracy, wherein the three struts 13 are the front strut, the middle strut, and the rear strut. The area between the front strut and the middle strut forms a front palletizing area 801, and the area between the rear strut and the middle strut forms a rear palletizing area 802. The front strut and the middle strut are provided with a first safety light barrier 91 for detecting the passages 82 in the front palletizing area 801, and the rear strut and the middle strut are provided with a first safety light barrier 91 for detecting the passages 82 in the rear palletizing area 802. With this setting, the separation is clear. When palletizing in small series, only the front pallet area 801 is open, i.e.For easy management and control, the palletizing gripper 7 palletizes only on the pallet 83 of the front pallet area 801. During large-scale palletizing, both the front pallet area 801 and the rear pallet area 802 are open for use, and the palletizing gripper 7 can palletize on the pallet 83 of the front pallet area 801 and the rear pallet area 802.

[0026] It is understood that the front of the front palletizing area 801 is the inlet of the vertical palletizing device for film reels, at which position the gripping point of the film reel is set, and after the palletizing gripper 7 has gripped the film reels at the gripping point of the film reels, it will move to the palletizing area 8 for palletizing.

[0027] To further ensure the safety of the vertical film reel palletizer, a second safety photoelectric sensor 92 for detecting pedestrians entering the palletizing area 8 is installed on the feet 11 of each of the uprights 1. If the transmitter with the second safety photoelectric sensor 92 is blocked, the light emitted by the transmitter cannot be received by the receiver of the second safety photoelectric sensor 92, indicating that someone is entering the palletizing area 8. There is a risk of collision between personnel and the moving palletizing gripper 7. Therefore, the second safety photoelectric sensor 92 returns a signal to the film reel packaging control system, and the film reel packaging control system immediately controls the vertical film reel palletizer to stop.

[0028] In particular, the column 12 of the column 1 is provided with a transversely extending first guide rail 31 and a first rack located on the side of the first guide rail 31, the bottom of the cross slide 2 being slidably connected to the first guide rail 31 by a first sliding block; the front and rear drive assembly 3 comprises a first reduction gear 32 arranged on the cross slide 2, a transmission shaft 33 drivingly connected to the first reduction gear 32, a first gear 34 nested on the transmission shaft 33, the cross slide 2 being provided with a bearing seat 35 supporting the transmission shaft 33, the first gear 34 engaging with the first rack for transmission.Driven by the forward and reverse rotation of the first reduction gear 32, the drive shaft 33 drives the first gear 34 to rotate and cooperate with the first rack, thereby effectively transmitting the power to the cross slide 2 and achieving precise movement of the cross slide 2 on the column 12 of the column 1 under the guidance of the first slide block and the first guide rail 31, that is, the cross slide 2 can drive the palletizing gripper 7 and the film reel to move freely in the palletizing area 8.

[0029] Furthermore, the transverse slide 2 is provided with a transversely extending second guide rail 51 and a second rack 52 located on the side of the second guide rail 51, the bottom of the longitudinal slide 4 being slidably connected to the second guide rail 51 by a second slide block; the left and right drive assembly 5 includes a second reduction gear 53 arranged on the longitudinal slide 4 and a second gear arranged on the output end of the second reduction gear 53, the second gear being engaged with the second rack 52 for transmission.Driven by the forward and reverse rotation of the second reduction gear 53, the drive shaft 33 drives the second gear and the second rack 52 to rotate and cooperate, thereby effectively transmitting the power to the longitudinal slide 4 and achieving precise movement of the longitudinal slide 4 on the cross slide 2 under the guidance of the second slide block and the second guide rail 51, that is, the longitudinal slide 4 can drive the palletizing gripper 7 and the film reel to move freely in the palletizing area 8.

[0030] The elevator 6 further includes a longitudinal support, a lead screw rotatably mounted on the longitudinal support, a lead screw nut nested on the lead screw, a third guide rail 63 vertically mounted on the longitudinal support, and a third reduction gear drivingly connected to the lead screw. The lead screw nut is fixedly connected to the palletizing gripper 7, and the rear side of the palletizing gripper 7 is connected to the third guide rail 63 via a third slide block 64. The third reduction gear drives the palletizing gripper 7 to move up and down through the transmission of the lead screw and the lead screw nut. Due to the high transmission stability of the lead screw structure, the palletizing gripper 7 can move smoothly and accurately to a predetermined position. Of course, the elevator 6 can use a linear module with a high degree of integration.

[0031] The palletizing gripper 7 is capable of moving along three axes, not only accurately grasping and placing film reels, but also flexibly moving and avoiding within the palletizing area 8 to meet the requirements of automated palletizing.

[0032] In particular see Fig. 4 and Fig.5 that the palletizing gripper 7 comprises a base 71, an outer sleeve 721 provided on the base 71, an inner sleeve 722 extending through the outer sleeve 721, a gripping sleeve 723 fixedly connected to the lower end of the inner sleeve 722, a guide plug 724 connected to the lower end of the gripping sleeve 723, a cylinder holder 731 fixedly connected to the upper side of the inner sleeve 722, a cylinder 732 arranged on the cylinder holder 731, wherein the cylinder holder 731 is located above the outer sleeve 721, wherein a clamping push rod 77 is inserted into the inner sleeve 722 and extends into the gripping sleeve 723, wherein the end of the piston rod of the cylinder 732 is driven by the upper side of the clamping push rod 77;wherein the side wall of the grip sleeve 723 is arranged in a circumferential arrangement with at least two clamp arm holes 7231, wherein a clamp arm guide block 74 is fixed to the top of the guide plug 724 within the grip sleeve 723, wherein each clamp arm hole 7231 is provided with a clamping clamp arm 75, wherein each clamping clamp arm 75 is drivingly connected to the clamping push rod 77, wherein each clamping clamp arm 75 protrudes from the clamp arm hole 7231 or retracts back to the grip sleeve 723 under the guidance of the clamp arm guide block 74;

[0033] Before palletizing, the film reel was transferred from the horizontal positioning state to the vertical positioning state by the turning machine. First, the gripping sleeve 723 of the palletizing gripper 7 is aligned downward with the paper roll core of the film reel, and then the palletizing gripper 7 is lowered so that the gripping sleeve 723 extends into the paper roll core of the film reel. Then, the cylinder 732 drives the clamping push rod 77 to descend vertically, and the clamping push rod 77 drives all the clamping clamp arms 75 to extend along the guide ramp of the clamp arm guide block 74 outside the clamp arm hole 7231 to clamp the film reel.

[0034] The end of the piston rod of the cylinder 732 extends downward and is connected to the top of the clamping push rod 77 by a joint 733 to form a coaxial line between the cylinder 732 and the clamping push rod 77; the cylinder support 731 comprises a horizontally arranged upper plate 7311 and a lower plate 7312 and a strut 7313 connecting the upper plate 7311 and the lower plate 7312, the cylinder 732 being arranged on the top of the upper plate 7311 and the joint 733 being arranged between the upper plate 7311 and the lower plate 7312.By disposing the cylinder bracket 731 above the outer sleeve 721, the piston rod of the cylinder 732 can be arranged downward coaxially with the clamping push rod 77, thereby ensuring that the force of the cylinder 732 can be transmitted linearly and smoothly to the clamping push rod 77, thereby solving the occurrence of the movement of the clamping push rod 77 and the clamping, and ensuring that the palletizing gripper 7 grips and releases the film reel smoothly and smoothly during long-term work.

[0035] During palletizing, the palletizing gripper 7 grips the film reel as it moves across the pallet 83. The palletizing gripper 7 then lowers by an adjustment height by means of the elevator 6, so that the palletizing gripper 7 stably places the film reel on the pallet 83. However, in reality, the pallet 83 has different heights or the support surface of the pallet 83 is tilted. It is difficult to determine whether the film reel has been stably placed on the pallet 83 or is still hanging. Therefore, the palletizing gripper 7 provided in this embodiment cleverly forms the cylinder bracket 731, the cylinder 732, the clamping push rod 77, the inner sleeve 722, the grip sleeve 723, and the clamping clamp arm 75 as a whole.In addition, a downwardly extending slide rod 761 is fixed to the underside of the bottom plate 7312, and the outer sleeve 721 is externally provided with a guide sleeve 762 for guiding the vertical movement of the slide rod 761 and a sensor 763 for detecting the lower end of the slide rod 761. In a natural state, the cylinder bracket 731 is pressed onto the upper side of the outer sleeve 721 due to the total gravity of the floating assembly, so that the lower end of the slide rod 761 has been in the state of triggering the sensor 763. When the film reel is stably placed on the pallet, the elevator 6 drives the palletizing gripper 7 to continue lowering.At this time, since the tension clamp arm 75 is in the state of tensioning the film reel, the floating assembly is stationary and the base 71 and the outer sleeve 721 will continue to descend relative to the floating assembly, whereby the cylinder bracket 731 and the outer sleeve 721 will be separated, and the sensor 763 on the outer sleeve 721 will also be unable to detect the lower end of the slide rod 761 due to the lowering, and then feedback signals are sent to the control system indicating that the film reel has been palletized in place, and the elevator 6 can stop the drive.

[0036] Preferably, the sliding cooperation of the slide rod 761 and the guide sleeve 762 also restricts the rotation of the floating assembly relative to the outer sleeve 721 and the base 71, which not only performs circumferential positioning of the floating integral to prevent the floating assembly from rotating to affect the orientation of the film reel, but also prevents the lower end of the slide rod 761 from self-rotating due to the floating assembly and disconnecting the triggering of the sensor 763.

[0037] The base 71 is also provided with a rotary drive assembly 78 for driving the rotation of the outer sleeve 721, the rotary drive assembly 78 comprising a motor mount 781 fixed to the base 71, a motor 782 provided on the motor mount 781, a drive gear 783 fixed to the output end of the motor 782, a bearing gear 784 rotatably connected to the base 71, the drive gear 783 being driven by a transition gear 785 meshing with the bearing gear 784, the bearing gear 784 being coaxial with the outer sleeve 721, and the outer sleeve 721 being fixed above the bearing gear 784. When the clamp arm 75 of the palletizing gripper 7 grips the film reels tensile strength, because the cylinder holder 731 is under its own gravity and the gravity of the film reels, the cylinder holder 731 is pressed onto the outer sleeve 721.When the motor 782 drives the drive gear 783 to rotate under the transmission of the transition gear 785, it drives the bearing gear 784 to rotate, so that the outer sleeve 721, the cylinder holder 731, the inner sleeve 722, the gripping sleeve 723 and the film spools form an integral synchronous rotation, thereby achieving the effect of changing the direction of the film spools.
