Description

Technical Field

[0001] The invention belongs to the technical field of sorting machines, and in particular relates to an automatic storage bin for material tubes. Background Art

[0002] In the tube loading mechanism of the chip testing and sorting machine, the staff puts the tube filled with chips into the feeding mechanism, and the chips enter the machine through the mechanism for testing. At this time, a mechanism is needed to collect the empty tubes. In the past, the collecting bin used the method of letting the tubes fall into the bin naturally by gravity. This method will cause impact, damage the tubes, and cause the tubes to deform. When falling, the collision between the tubes and the collecting bin, and between the tubes will make a lot of noise, especially for metal tubes, which will directly damage the hearing of the staff. In addition, the placement of the tubes is disorderly and chaotic, which is not conducive to recycling. They need to be stacked neatly when used again. Summary of the invention

[0003] In view of this, the present invention aims to propose an automatic storage bin for material tubes to solve the problem that when the existing material tubes are recycled, there is a lot of noise, they are easy to be damaged, and they are placed in a disorderly manner, making recycling difficult.

Two tube push claws are installed at the movable end of the cylinder 103, and the tube push claws are used to push the material tube to move. Among them, one tube push claw is connected to the cylinder 103 through a buffer unit, and the buffer unit plays a buffering role in the process of pushing the material tube.

[0045] In one or more embodiments, a speed control valve 104 is further provided on one side of the cylinder 103. Both the cylinder 103 and the speed control valve 104 are connected to an external controller. The speed control valve 104 is used to supply air to the cylinder and control the movement speed of the cylinder 103 through the controller.

[0046] Preferably, in order to maintain the balance of the material tube when it is placed, the material tube bottom rails 107 are symmetrically installed on both sides of the tube pushing base plate 101.

[0047] In one or more embodiments, a tube-pushing claw mounting base plate 102 is fixedly mounted above the movable end of the cylinder 103, and a left tube-pushing claw 106 is rotatably mounted on one side of the tube-pushing claw mounting base plate 102 through a buffer unit, and a right tube-pushing claw 110 is rotatably mounted on the other side. A limiting hole 111 is also provided on both sides of the tube-pushing claw mounting base plate 102, and the limiting hole 111 is used to limit the rotation angle of the left tube-pushing claw 106 and the right tube-pushing claw 110, so that the maximum rotation angle of the left tube-pushing claw 106 and the right tube-pushing claw 110 is 90°.

[0048] The left tube pushing claw 106 and the right tube pushing claw 110 are provided with weight-reducing holes on their upper parts and counterweights on their lower parts, so that the left tube pushing claw 106 and the right tube pushing claw 110 are naturally kept vertical when they are not subject to external forces but only to gravity. Figure 5 Preferably, the sides of the left tube-pushing claw 106 and the right tube-pushing claw 110 close to the material tube are both flat, so as to facilitate contact with the material tube.

[0049] In one or more embodiments, the buffer unit includes a front push claw buffer block 105, a front push claw buffer shaft 108 and a spring 109. A U-shaped groove is provided on one side of the push tube claw mounting base plate 102, and the front side push claw buffer shaft 108 is installed in the U-shaped groove. The front side push claw buffer shaft 108 is externally movably sleeved on the front side push claw buffer block 105, and the left side push tube claw 106 is rotatably installed on the outer side of the front side push claw buffer block 105, and the end of the front side push claw buffer shaft 108 away from the left side push tube claw 106 is sleeved on the spring 109.

[0050] The tray assembly 200 includes a collecting bin tube carrier plate 201, a collecting bin tube carrier base plate 202, a screw connecting block 203, a right slider fixing seat 204, a left slider fixing seat 205, a zeroing baffle 206 and a limiting impact block 207. The collecting bin tube carrier plate 201 is used to place multiple layers of material tubes, and the bottom is connected to the lifting collecting assembly 3 through a fixing seat, and the zeroing baffle 206 is installed on the fixing seat.

[0051] Preferably, a limiting impact block 207 for limiting is also installed on the fixing seat. In one or more embodiments, there are two fixing seats, namely the right slider fixing seat 204 and the left slider fixing seat 205, which are symmetrically installed on both sides of the receiving bin tube plate 201.

[0052] The receiving bin tube base plate 202 is installed below the receiving bin tube base plate 201, the screw connecting block 203 is installed in the middle of the bottom of the receiving bin tube base plate 202, the right slider fixing seat 204 and the left slider fixing seat 205 are symmetrically installed on both sides, the zeroing baffle 206 is installed on the right slider fixing seat 204, and the limit impact block 207 is installed on the left slider fixing seat 205. In one or more embodiments, the thickness of the receiving bin tube base plate 201 is different, so that the material tube has high and low positions after being placed on it, and the high position is located at the chip discharge port side, which effectively prevents the residual chips in the material tube from falling out from the gate.

[0053] The lifting material receiving assembly 300 includes a material receiving bin base plate 301, a guide rail 302, a slider 303, a motor 304, a screw 305, a screw nut 306, a motor mounting plate 307, a screw fixing seat 308, a zeroing sensor 309, a buffer 310, a stopper 311, a fixing seat 312, a left baffle 313, a right baffle 314, a material tube end baffle 315, a photoelectric sensor 316, a sensor mounting plate 317 and a material tube outer baffle 318.

[0054] The receiving bin substrate 301 is fixedly connected to the feeding mechanism. The receiving bin substrate 301 is provided with a driving unit for driving the tray assembly 200 to move up and down and a guiding unit for guiding the tray assembly 200. Blocks 311 are provided at both ends of the guiding unit, and a baffle is provided on the outside. The receiving bin substrate 301 is also equipped with a baffle and a baffle 318 outside the material tube. The three cooperate to place the material tube and limit the position of the material tube. Preferably, both sides of the baffle 318 outside the material tube are also provided with a limiting part, and the length of the limiting part is different, so that when the baffle 318 outside the material tube limits the position of the material tube, the material tube is in an inclined state. In one or more embodiments, a buffer 310 and a zeroing sensor 309 are also provided on the receiving bin substrate 301, and the signal of the zeroing sensor 309 is connected to the controller. The zeroing sensor 309 is used to calibrate the motion position. A zeroing action must be performed every time the machine is turned on. The buffer 310 is used to reduce the impact of falling, to prevent the collision of the receiving bin substrate 301 when the motor 304 is powered off or in other cases when the free fall falls.

[0055] In one or more embodiments, a material tube end baffle 315 is installed on one side of the receiving bin substrate 301, and a photoelectric sensor 316 is installed on the material tube end baffle 315, and the photoelectric sensor 316 signal is connected to the controller. Preferably, the photoelectric sensor 316 is installed on the outside of the material tube end baffle 315 through a sensor mounting plate 317.

[0056] In order to maintain force balance, the drive unit is installed in the middle of the receiving bin substrate 301. The drive unit includes a motor 304, a screw rod 305 and a screw rod nut 306. The lower end of the screw rod 305 is connected to the motor 304, and the motor 304 signal is connected to the controller. The upper end of the screw rod 305 is installed on the receiving bin substrate 301 through a screw rod fixing seat 308, and the screw rod nut 306 is sleeved on the outside. The screw rod nut 306 is sleeved on the screw rod connecting block 203 outside to drive the screw rod connecting block 203 to move. Preferably, the motor 304 is connected to the receiving bin substrate 301 through a motor mounting plate 307.

[0057] In one or more embodiments, the guide unit includes a guide rail 302 and a slider 303. The two guide rails 302 are symmetrically installed on both sides of the screw rod 305. The slider 303 is installed on each guide rail 302. The upper and lower ends of the guide rail 302 are provided with a stopper 311 for limiting the position. Preferably, the stopper 311 is connected to the receiving bin base plate 301 through a fixing seat 312. A baffle is provided on the outer side of each guide rail 302, which is a left baffle 313 and a right baffle 314.

[0058] The working principle of the automatic storage bin for material tubes is as follows: For the convenience of understanding, this embodiment is described by taking the case where three material tubes are placed on each layer of the tube plate 201 of the storage bin,

[0059] like Figures 8 to 10 As shown, at this time, the tube-pushing claw starts to push the first tube G1, and there is no tube in the receiving bin. The controller controls the cylinder 103 to work, and the tube-pushing claw 106 on the left side of the cylinder 103 and the tube-pushing claw 110 on the right side are driven by the cylinder 103 to push the first tube G1 into the tube-carrying plate 201 of the receiving bin.

[0060] like Figures 11 to 13 As shown, after the first material tube G1 is pushed into place (this step can be achieved by delay control inside the controller), the controller controls the cylinder 103 to start retracting. Since the left tube pushing claw 106 is rotatably installed on the outside of the front side pushing claw buffer block 105, and the right tube pushing claw 110 is rotatably installed on the outside of the tube pushing claw mounting base plate 102, when the left tube pushing claw 106 and the right tube pushing claw 110 hit the second material tube G2, the second material tube G2 will squeeze the left tube pushing claw 106 and the right tube pushing claw 110 from the back, so that the left tube pushing claw 106 and the right tube pushing claw 110 flip over to the bottom of the second material tube G2.

[0061] After the cylinder 103 is retracted into place, the left tube pushing claw 106 and the right tube pushing claw 110 are separated from the second material tube G2 and are not affected by the squeezing force of the second material tube G2. At this time, the left tube pushing claw 106 and the right tube pushing claw 110 are restored to their initial states.

[0062] The controller controls the cylinder to move forward, pushing the second material tube G2 into the tube-carrying plate 201 of the receiving bin. At this time, the receiving bin contains two material tubes.

[0063] like Fig.14 As shown, the cylinder 103 pushes the third material tube G3 to the tube plate 201 of the receiving bin in the same way. At this time, the material tube is limited and blocked by the two ends of the baffle plate 318 outside the material tube, and the spring 109 is compressed by the force of the left tube push claw 106. At this time, the three material tubes present a certain inclination relative to the vertical direction. After the third material tube G3 is in place, the controller controls the cylinder 103 to retract. The photoelectric sensor 316 senses the material tube G and transmits the signal to the controller. The controller controls the motor 304 to drive the screw rod 305 to rotate. Under the action of gravity, the tube plate 201 of the receiving bin descends along with the screw rod nut 306.

[0064] like Figures 15 to 17As shown, the tube plate 201 of the receiving bin pushes in the fourth material tube G4. Since the material tubes are in a "concave" shape, if all the material tubes are placed in a vertical direction, when the material tubes are pushed in from the second layer, the material tubes will be affected by gravity, and the upper material tubes will fall into the lower material tubes. As a result, the lower material tubes are tilted at a certain angle relative to the vertical direction. In order to ensure that before the upper material tubes are about to fall, the lower right corner of the fourth material tube G4 shown in the figure is placed on the surface of the third material tube G3 of the lower layer to ensure the stability of the material tubes so that they can be pushed into the receiving bin smoothly. After the fifth and sixth material tubes are pushed into the tube plate 201 of the receiving bin, the state of the second layer of material tubes of the tube plate 201 of the receiving bin is the same as that of the first layer of material tubes, both of which are in an inclined state, as shown in FIG. Fig.14 .

[0065] like Fig.18 As shown, the above method is analogous until the bin is full. The left side of the figure is the chip discharge port, so the left side of the receiving bin tube plate 201 is high and the right side is low, to ensure that the material tube can be blocked by the outer baffle 318 of the material tube after entering the receiving bin and then flattened. If there are residual chips in the material tube that have not been poured out, they can be retained in the material tube and will not slide out of the material tube and cause damage to the chips.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
