Description

Technical Field

[0001] The utility model relates to a chip collecting and separating bin and a system, belonging to the technical field of chip collecting and processing. Background Art

[0002] Machining refers to the use of machine tools to perform cutting, polishing and other processing techniques on metal materials to process the workpiece into the required shape and size. During the machining process, chips will be generated due to the relative movement between the machining tool and the workpiece. Chips are waste materials formed when metal materials are separated from the workpiece due to the cutting force and the friction between the cutting part and the workpiece material during the machining process.

[0003] The existing intelligent machining workshops require not only automation and intelligence, but also environmental protection. The chips generated must be collected and transported to the dryer to dry the cutting fluid and finally pressed into blocks. The chips to be processed need to be transported to the corresponding dryers. Therefore, a chip collection and sorting silo and system are needed to collect chips and transport the collected chips to the dryer for processing. When the amount of chips in the workshop is large, multiple dryers will be used according to the amount of chips to be processed, and they are also required to distribute the collected chips to the corresponding dryers for processing as required. Summary of the invention

[0004] The utility model aims at the deficiencies in the prior art and provides a chip collecting and separating bin and a system.

[0007] The beneficial effects of the utility model are as follows: when the amount of chips is small, one conveying channel can be selected as the working channel. For example, the left conveying channel is the working channel, and the right conveying channel is the non-working channel. The chips are guided into the left conveying channel by rotating the baffle, and at the same time the baffle blocks the chips from entering the right conveying channel, ensuring that the chips entering the left conveying channel can be conveyed out of the chip separation bin under the operation of the left conveying mechanism, so as to convey the chips to the spin dryer at the corresponding position; when the amount of chips is large, the left and right conveying channels can be selected as the working channels, and the rotating baffle is in a vertical state so as not to interfere with the entry of chips from the two conveying channels, and the chips are conveyed through the left conveying mechanism and the right conveying mechanism in the left conveying channel and the right conveying channel respectively, so as to realize the chip separation of the collected chips and convey them to the spin dryer or the next chip separation bin, so as to supply chips to the spin dryers at different positions or to the next-level chip separation bin for further chip separation processing.

The large amount of chips not only includes the large amount of chips during the conveying process, but also includes the large amount of chips when the chip separation silo is used to store chips due to subsequent equipment maintenance. During transportation, the stirring mechanism can be started to stir them to ensure smooth transportation of the chips.

[0038] The left stirring mechanism 7 and the right stirring mechanism 8 both include a stirring shaft 13 and a stirring reducer 12 for driving the stirring shaft 13 to rotate. The stirring shaft 13 is rotatably arranged on the silo housing 1. The output shaft of the stirring reducer 12 is connected to the stirring shaft 13.

The left-handed spiral piece 15 and the right-handed spiral piece 14 rotate under the action of the stirring shaft 13, and can stir the chips in the conveying channel in different directions to avoid the chips in the silo from being suspended in the air.

[0039] The left-handed spiral blade 15 and the right-handed spiral blade 14 are symmetrically arranged on the stirring shaft 13. The left-handed spiral blade 15 and the right-handed spiral blade 14 are symmetrically designed, and the stirring effect of the chips in different directions is better.

[0040] The lower end or the upper end of the baffle 2 is rotatably arranged on the shell of the silo shell 1. The baffle 2 located in the silo shell 1 has three working positions: middle position, left position and right position. The baffle 2 in the silo shell 1 is in a vertical state, which is the middle position of the baffle 2. The chips of the left and right conveying channels 4 can pass through. When the free end of the baffle 2 swings to the left, which is the left position, the chips can be conveyed through the right conveying channel 4. The baffle 2 is tilted and has a certain material guiding effect. When the free end of the baffle 2 swings to the right, which is the right position, the chips can pass through the left conveying channel 3. The tilted baffle 2 can have a certain guiding effect on the chips.

[0041] The lower end of the baffle 2 is hinged to the silo shell 1, and a positioning tube 21 is provided on the upper part of the baffle 2, which also includes a positioning rod 22 and a blocking rod 23. The silo shell 1 is provided with a through hole for the positioning rod 22 to pass through. When the baffle 2 is in the middle position, the positioning rod 22 is plugged into the positioning tube 21. The blocking rod 23 is used to support the non-working surface of the baffle 2, and is respectively arranged on the left and right sides of the silo shell 1. The lower end of the baffle 2 can be connected to the silo shell by a hinge. There is a hinge fixing tube in the silo shell 1, and a hinge movable tube is provided at the lower end of the baffle. The two are arranged at an interval, and the hinge fixing tube and the hinge movable tube are connected by a pin shaft to realize the connection between the lower end of the baffle 2 and the silo shell 1; when the baffle 1 needs to be in the middle position, the baffle can be rotated to the middle position, and then the positioning rod 22 is passed through the through hole and plug-in cooperation with the positioning tube 21 to realize the middle position positioning of the baffle; when the baffle 2 is needed to be in the left position or the right position, the positioning rod 22 is pulled out, the baffle 2 tilts to the left, and the baffle rod 23 on the left side supports the baffle, so as to realize the left position positioning of the baffle; the baffle 2 tilts to the right, and the baffle rod 23 on the right side supports the baffle, so as to realize the right position positioning of the baffle.

[0042] A limit switch for detecting the working position of the free end of the baffle 2 is arranged in the silo housing 1. The position of the baffle 2 can be monitored in real time through the limit switch.

[0043] The limit switch includes a left limit switch 16 for detecting whether the baffle 2 is in the left position and a right limit switch 17 for detecting whether the baffle 2 is in the right position. The left limit switch 16 is arranged on the left side of the silo housing 1, and the right limit switch 17 is arranged on the right side of the silo housing 1. When the left limit switch 16 detects the baffle 2, it can be known that the free end of the baffle 2 is swung to the left at this time, and the chips pass through the right conveying channel 4; when the right limit switch 17 detects the baffle 2, it can be known that the free end of the baffle 2 is swung to the right at this time, and the chips pass through the left conveying channel 3; if both the left and right limit switches 17 do not detect the baffle 2, the baffle 2 is in the middle position of the silo housing 1, and its free end does not swing to the left or right side, and the chips can pass through the left conveying channel 3 and the right conveying channel 4.

[0044] The silo housing 1 is also provided with a left laser distance sensor 18 and a right laser distance sensor 19 for detecting the height of the chips in the left conveying channel 3 and the right conveying channel 4. The silo housing 1 is also provided with a laser distance sensor. When the subsequent equipment has problems and needs maintenance, the conveying mechanism can be stopped. The chip separation silo can also be used as a storage space for temporarily storing chips. When storing chips, the height of the chips in the silo can be detected by the laser distance sensor to avoid excessive chips. Therefore, the height of the chips in the corresponding conveying channel can be set according to needs to avoid the chips in the corresponding conveying channel of the silo housing 1 being too high to store the chips, and to avoid the problem of chips overflowing during the subsequent conveying of chips due to excessive chips.

[0045] The left conveying mechanism 5 and the right conveying mechanism 6 both include a conveying shaft 10 and a conveying reducer 9 for driving the conveying shaft 10 to rotate. The conveying shaft 10 is rotatably arranged on the silo shell 1. The conveying shaft 10 is provided with a conveying spiral blade 11. The output shaft of the conveying reducer 9 is connected to the conveying shaft 10. The chips fall onto the rotating conveying shaft 10 under the guidance of the V-shaped structure silo wall of the silo shell. Under the action of the conveying spiral blade 11, the chips entering the conveying channel can be guided and transported out of the silo shell 1. The discharge position of the chips can be located at the front or rear side of the silo shell 1; under the action of the conveying spiral blade 11, the chips can be sent out and sent to the next level of chip separation silo for further chip separation. Of course, they can also be transported to the spin dryer for processing through the chip conveyor 20.

[0046] Embodiment 1, as Figure 3 and Figure 4 As shown, the utility model also relates to a chip collecting and separating system, comprising a first-level chip collecting and separating bin as described above, and also comprising a chip conveyor 20 arranged at the discharge point of the chip collecting and separating bin at each level.

[0048] There are two conveying channels in the chip separation bin to realize the chip separation function. According to the different chip amounts, single-side or double-side simultaneous conveying can be selected, which is highly flexible and energy-saving. When the chip amount is small, one side of the conveying channel can be started for conveying. At this time, the baffle 2 is flipped to the side of the non-working channel to ensure that all the chips fall into the corresponding conveying channel. When the chip amount is large, the baffle 2 is placed in the middle of the bin shell 1, so that the chips fall into the conveying channels on both sides of the shell, i.e., the left and right conveying channels 4 for conveying or uniform conveying. The chip separation bin can not only be used to convey chips, but also as a chip storage space. When subsequent equipment has problems and needs maintenance, the chips can be temporarily stored in the chip separation bin. When the chip amount is not large, stirring is not required. When a large amount of chips is stored in the chip separation bin, the stirring mechanism can also be started, and the stirring shaft 13 rotates the stirring spiral blade to ensure that the chips are smoothly conveyed and avoid hanging in the air. The left-handed spiral blade 15 and The right-handed spiral blades 14 are symmetrically arranged on the stirring shaft 13 and can rotate in the opposite direction to the conveying spiral to stir the stored chips in different directions to avoid the chips in the chip silo being suspended in the air; the reducer on the chip silo can adopt frequency conversion control to adjust the conveying speed of the chips to avoid overload or underload; the conveying shaft 10 and the stirring shaft 13 are both connected to the silo shell 1 through bearings to operate stably and avoid shaft jumping; the baffle 2 in the middle of the chip silo shell 1 can be flipped left and right, and when one side is used for conveying, it can be flipped to the other side to ensure maximum chip entry space; the left limit switch 16 and the right limit switch 17 in the silo shell 1 can detect the position of the baffle 2 in time; the laser ranging sensor in the silo shell 1 can monitor the height of the chips in the silo in real time when the chip silo is used as a storage silo to meet the chip storage demand of the chip silo; a flexible connection can be adopted between the reducer and the shaft, such as a universal coupling, to meet the small swing of the shaft. The utility model has a compact layout structure, occupies a small space, is easy to maintain, and greatly improves work efficiency. It can be arranged at a centralized chip conveying terminal or in a space outside a workshop, and is not affected by the layout inside the workshop, thus freeing up a large amount of space for the workshop layout, ensuring that the workshop is clean and orderly, green and environmentally friendly, and realizing centralized maintenance of equipment, reducing the difficulty of maintenance, saving a large amount of money, and meeting the needs of intelligent and automated chip conveying, collection and separation of machine tools.
