TECHNICAL FIELD
[0001] The utility model belongs to the technical field of goods conveying, and particularly relates to a bagged goods automatic sequencing conveying and counting device and a bagged goods automatic picking machine. BACKGROUND
[0002] In the distribution center of e-commerce, the picking operation is the core of its operation system. The so-called picking is to find the required goods from the vast number of goods according to the customer order and deliver them to the customer. At present, many distribution centers are still labor-intensive industries, and the human resources directly related to the picking operation account for more than 50%. Moreover, the operation time of the picking operation accounts for 30-40% of the entire distribution center. In such an operation system, the labor intensity of the pickers is very high, the efficiency is very low, and errors are prone to occur, especially in the picking of single small goods (the smallest packaging unit required by the customer, such as a bag of tea or a bag of snacks) in the form of loose packing. According to data, the cost of picking operation accounts for about 40-60% of the operating cost of the distribution center. Obviously, automatic picking is in great need, and the only mature and applicable automatic picking equipment at present is the A-frame, but it is only suitable for goods that can be neatly stacked, such as boxes, cans, bottles, etc. with regular shape and certain rigidity, and its application range is limited. Moreover, even if the A-frame is used, the restocking operation still relies on manual restocking. However, manual restocking also has high labor intensity, low efficiency and high cost, and therefore cannot realize complete automatic picking.
[0003] The proportion of bagged goods packed in paper bags or plastic bags in the picking operation of goods is very large. The bagged goods are non-rigid, irregular in shape, and not accurate in size, and are unstable in stacking height, and therefore cannot be neatly stacked on the A-frame. Therefore, there is currently no practical automatic picking equipment for bagged goods. If a bag-by-bag counting device for randomly stacked bagged goods can be provided and used for automatic counting of bagged single small goods, and manual restocking is not required, it is possible to realize automatic picking, which will have a positive significance for the picking operation of e-commerce distribution.

DETAILED DESCRIPTION
[0049] The specific implementation scheme of the present utility model is described in detail below with reference to the accompanying drawings. Example 1
[0050] like Figure 1 The device for automatically sorting, conveying and counting bagged goods shown in the figure comprises a plurality of vibrating conveying sections 100 arranged in sequence, each vibrating conveying section 100 comprising a loading plate 1, a vibrating support member 2 obliquely connected to the loading plate 1 and used to support the loading plate 1, an exciter M for driving the vibrating support member 2 to vibrate, and a base 4, wherein the vibrating support member 2 is connected to the base 4, and one end of the vibrating support member 2 connected to the loading plate 1 is tilted in the opposite direction of the conveying direction, and further comprises a controller 5 for controlling the start and stop of each vibrating conveying section 100, and any vibrating conveying section 100 is equipped with a device for detecting the vibrating support member 2. Whether there are bagged goods 18 on the vibrating conveying section 100, each bag sensor 6 is electrically connected to the controller 5, and the detection result is sent to the controller 5. The controller 5 controls the start and stop status of each vibrating conveying section 100 in the two adjacent vibrating conveying sections 100 according to the detection results of the bag sensors 6 corresponding to the two adjacent vibrating conveying sections 100. The end face of the carrier plate 1 perpendicular to its conveying direction is an arc or polygon with a concave middle part. In this embodiment, the end face of the carrier plate 1 perpendicular to its conveying direction is preferably an inverted trapezoidal polygon, thereby forming a groove 19.
[0051] For convenience of description, the bagged goods 18 will be referred to as bags hereinafter. The length, width and depth of the groove 19 are set in proportion to the size of the bags to be conveyed. Generally, the length can be 0.5 to 2 times the diagonal length of the bags, the width can be 1 to 2 times the diagonal length of the bags, and the depth can be 0.5 to 2 times the thickness of the bags, with the small bags having a larger value and the large bags having a smaller value, so that one size of the groove 1 can be used to convey bags of several sizes.
[0052] As shown in Figure 2 and Figure 3 , in this embodiment, at least one vibration support 2 is arranged at each of the upstream and downstream ends of the carrier plate 1. The two vibration supports 2 are parallel to each other. One end of the vibration support 2 is connected to the bottom surface of the carrier plate 1, and the other end extends downward and is fixed to the base 4. For the horizontally arranged carrier plate 1, the angle a between the normal line of the plane of the vibration support 2 and the bottom surface of the carrier plate 1 is the angle of projection. In this embodiment, a is set to 20°. In practical applications, the size of the angle of projection a can be adjusted according to the height of projection. In this embodiment, the vibration support 2 is preferably a reed. In practical applications, the vibration support 2 can also be a rod, with both ends of the rod being hingedly connected to the base 4 and the carrier plate 1, respectively.
[0053] The exciter M can be a commonly used electromagnetic type, i.e., an electromagnetic armature pulse mechanism. The electromagnet 301 of the exciter M is fixed to the base 4 via a support, and the electromagnetic armature 302 is tightly connected to the vibration support 2. When a pulse power source is provided to the electromagnet 301, the electromagnetic armature 302 is driven by the electromagnet 301 to drive the vibration support 2 to vibrate. The end of the vibration support 2 connected to the carrier plate 1 has the largest amplitude, and the vibration trajectory thereof can be regarded as a straight line with an angle of projection a, as shown by the dashed arrow in Figure 3 . The length of the arrow is the amplitude of the top end of the vibration support 2. The vibration supports 2 at the upstream and downstream ends of the carrier plate 1 vibrate synchronously and with the same amplitude, thereby driving the carrier plate 1 to move obliquely upward and downward along the dashed arrow at an angle of 20°. The bagged goods 18 are thrown upward by the carrier plate 1 for a short distance and then fall down. After touching the carrier plate 1, the bagged goods 18 are thrown upward again, and the continuous jumping movement continues, thereby conveying the bagged goods 18 downstream. The superposed bags are separated in this process, and the bags in parallel are also separated in this process. For bags that are difficult to separate, the angle of projection a (i.e., the upward angle of the vibration support 2) can be increased to throw the bagged goods 18 higher and increase the probability of vibration separation.
[0054] The carrier plate 1 is made into a groove-shaped structure, which has a strong oblique throwing effect at the bottom and is mainly used for conveying. The throwing effect of the two side surfaces is slightly weak, which is mainly used for constraint, so that the bagged goods 18 naturally slide to the middle of the groove 19 while being vibrated and conveyed, thereby being constrained in the middle of the groove 18 in the process of continuous jumping.
[0055] The bag sensor 6 in this embodiment is a reflective photoelectric switch 8 to sense the presence or absence of the bagged goods 18 in the respective monitored recess 19, see Figure 1 For the sake of simplicity and easy observation of the drawings, the mounting brackets of the bag sensors and the fasteners and other components at various places of the device are omitted, and the same applies to the other drawings hereinafter, and various mounting brackets, fasteners and the like will be omitted and will not be described one by one.
[0056] The two adjacent object carrier plates 1 in the same layer and downstream of the upstream end of the object carrier plate 1 are preferably bent downward to form a folded edge portion 101, and the two adjacent object carrier plates 1 are opposite to each other at the folded edge portion 101. In this embodiment, the inclination angle of the folded edge portion 101 is the same as or slightly larger than the throwing angle a, preferably the same, and the inclination angle of the folded edge portion 101 is determined based on the non-interference with the vibration of the upstream adjacent object carrier plate 1.
[0057] The folded edge portion 101 is provided to solve the problem that many bagged goods 18 have a condition that the edges or corners of the packaging bags are bent or even hooked. If there is no folded edge portion 101, once the hooked edge of the bagged goods 18 is trapped in the gap between the two adjacent object carrier plates 1, when the two object carrier plates 1 approach, the bagged goods 18 will be squeezed and clamped, causing the two object carrier plates 1 to be stuck, reducing or losing the vibration function. When the two object carrier plates 1 are separated again, the hooked edge of the bagged goods 18 is still trapped in the gap as shown, and most of the bagged goods 18 cannot be thrown out, and the conveying process will be interrupted. Figure 4 Figure 5 Figure 4 Figure 4 Figure 5 The folded edge portion 101 not only supports the hooked edge of the bagged goods 18 below the gap between the object carrier plates 1, but also continuously completes the throwing and conveying by means of the direct pushing action of the front edge of the adjacent upstream object carrier plate 1 on the hooked edge of the bagged goods 18, thereby eliminating the hooked edge trapping failure. Figure 6 Figure 7 The front and rear hooked edges of the bagged goods 18 are respectively shown to be pushed, wherein Figure 6 The front hooked edge of the bagged goods 18 is shown to be pushed away from the joint when the object carrier plate 1 of the present vibrating conveying section is at the lowest vibration position and the object carrier plate 1 of the adjacent upstream vibrating conveying section is at the highest vibration position. Figure 7 The bagged goods 18 are pushed from the rear hook edge when the carrier plate 1 of the current vibration conveying section is at the highest vibration position and the carrier plate 1 of the adjacent upstream vibration conveying section is at the lowest vibration position. In practical applications, the hook edge gap problem can also be solved by setting the carrier plates 1 of the vibration conveying sections in a manner that the upstream section is higher and the downstream section is lower, or in a manner that the upstream carrier plate is higher and the downstream carrier plate is lower, without setting the folding part. These two conventional joint conveying methods either increase the conveying space, cannot realize the same height conveying, and cannot adapt to some narrow conveying space scenes, or reduce the conveying speed and efficiency, but are beneficial to vibration separation.
[0058] The control method of the above-mentioned automatic sorting, conveying and counting device for bagged goods is as follows: a) if the current vibration conveying section has bags and the adjacent downstream section has no bags, the two sections are vibrated at the same time until the adjacent downstream section senses the bags and / or the current section senses no bags, and then the current vibration conveying section stops vibrating; b) if the current vibration conveying section and the adjacent upstream section have no bags, the current section does not vibrate; c) if the current section and the adjacent downstream section have bags, the current section does not vibrate.
[0059] The sorting, conveying and counting control circuit caused by the above-mentioned automatic sorting control method is as shown in FIG. 6. Figure 8 Any vibration exciter M (n) in the middle is connected to one end of a single-pole double-throw relay Q (n) , one normally open relay P (n) and one normally closed relay W (n) , the common terminal of the single-pole double-throw relay Q (n) is connected to one end of the normally closed relay W (n) corresponding to the vibration exciter M (n) , the other end of the vibration exciter M (n) is connected to one pole of the power supply, the other end of the normally closed relay W (n) is connected to the normally open terminal of the single-pole double-throw relay Q (n-1) adjacent to the upstream, the normally open terminal of the single-pole double-throw relay Q (n) is connected to the normally closed relay W (n+1) corresponding to the vibration exciter M (n+1) adjacent to the downstream, the normally closed terminal of the single-pole double-throw relay Q (n) is connected in series with the normally open relay P (n-1) corresponding to the vibration exciter M (n-1) adjacent to the upstream, and the normally open relay P (n) is connected in series between the normally closed terminal of the single-pole double-throw relay Q (n+1) corresponding to the vibration exciter M (n+1) adjacent to the downstream and the other pole of the power supply.
[0060] Compared with the middle vibrator M (n) , the vibrator M at the upstream end (1) Omit one SPDT relay Q and one normally closed relay W, and keep one normally open relay P (1) , the exciter M (1) One end is connected to the adjacent downstream exciter M (2) Corresponding normally closed relay W (2) Connect the other end to one pole of the power supply.
[0061] Compared with the middle vibrator M (n) , the vibrator M at the downstream end (t) Omit a normally open relay P and retain a single-pole double-throw relay Q (t) and a normally closed relay W (t) . n is a positive integer greater than 1 and less than t.
[0062] The control end of the single-pole double-throw relay Q, the control end of the normally-open relay P and the control end of the normally-closed relay W corresponding to the same exciter M are connected in parallel and electrically connected to the controller (5).
[0063] When situation a) occurs between any two adjacent vibration conveying sections (100), the controller (5) controls the exciter M of the vibration conveying section. (n) Corresponding single-pole double-throw relay Q (n) The normally open terminal No is connected to the common terminal Com, and the normally closed relay W (n) Disconnect, normally open relay P (n) Closed, the adjacent downstream section vibrates the conveying section (100) of the vibrator M (n+1) Corresponding single-pole double-throw relay Q (n+1) The normally closed terminal Nc is connected to the common terminal Com, and the normally closed relay W (n+1) Closed, the exciter M of two adjacent vibration conveyor sections (n) and vibrator M (n+1) At the same time, the vibration is started until the downstream vibration conveying section adjacent to the vibration conveying section senses that there is a bag and / or the vibration conveying section senses that there is no bag, the exciter M of the vibration conveying section (n) Stop vibration.
[0064] When situation b) occurs between any two adjacent vibration conveying sections (100), the controller (5) controls the exciter M of the vibration conveying section (100) (n) Corresponding single-pole double-throw relay Q (n) The common terminal Com and the normally closed terminal Nc are connected, and the normally closed relay W (n) Closed, adjacent upstream exciter M (n-1) Corresponding normally open relay P (n-1) When disconnected, the vibration conveying section (100) does not vibrate.
[0065] When any two adjacent vibrating conveying sections (100) are in case c), the controller (5) controls the vibrator M (n) of the present vibrating conveying section (100) to be off (n) , the normally open terminal No of the corresponding single-pole double-throw relay Q (n) is connected to the common terminal Com, the normally closed relay W (n) is off, the vibrator M (n+1) of the adjacent downstream vibrating conveying section (100) is on; the normally closed terminal Nc of the corresponding single-pole double-throw relay Q (n+1) is disconnected from the common terminal Com, the normally closed relay W (n+1) is on, and the present vibrating conveying section (100) is not vibrated.
[0066] The above circuit is described by taking any three vibrating conveying sections n-1, n and n+1 as an example, as shown in Figure 8 . In the figure, Q (n) is the single-pole double-throw relay corresponding to the vibrator M (n) of the nth vibrating conveying section 100, which is a switching switch that can switch the conduction between the normally open and normally closed paths. When the power supply of the operating coil is not connected, the single-pole double-throw relay Q (n) connects the common terminal Com and the normally closed terminal Nc. When the operating coil is powered on, the single-pole double-throw relay Q (n) connects the common terminal Com and the normally open terminal No. W (n) is the normally closed relay corresponding to the vibrator M (n) of the nth vibrating conveying section 100, P (n) is the normally open relay corresponding to the vibrator M (n) of the nth vibrating conveying section 100, the operating coil of the normally closed relay W (n) and the normally open relay P (n) are all connected in parallel with the operating coil of the single-pole double-throw relay Q (n) , and the rest of the sections are similar.
[0067] When the bag sensor 6 of the nth vibrating conveying section 100 triggers a bag signal, the controller 5 connects the power supply of the operating coil of all the relays corresponding to the vibrating conveying section 100, thereby connecting the common terminal Com and the normally open terminal No of the corresponding single-pole double-throw relay Q (n) , closing the normally open relay P (n) , and simultaneously disconnecting the normally closed relay W (n) . Conversely, when the bag sensor 6 of any vibrating conveying section 100 loses the bag signal, the corresponding relays of the vibrating conveying section 100 are reset.
[0068] In this way, the vibrating conveying section 100 is vibrated by the vibrator M Figure 8The relays connected in the circuit shown can start and stop the vibration of each vibration conveying section 100 according to the signal of the bag sensor 6. Take the nth vibration conveying section 100 as an example: when there is a bag in this section, the single-pole double-throw relay Q (n) The normally open terminal No is connected to the common terminal com, and the normally closed relay W (n) Disconnect, normally open relay P (n) If the downstream n+1 vibration conveying section 100 has no bag, the single-pole double-throw relay Q corresponding to the n+1 vibration conveying section 100 will be turned on. (n+1) The normally closed terminal Nc is connected to the common terminal com, and the normally closed relay W (n+1) Conducting, and SPDT relay Q (n)、 SPDT relay Q (n+1) Two connected exciters M (n)、 M (n+1) All of them start to vibrate from DC+, until the bagged goods 18 arrive at the n+1th vibration conveyor section 100, triggering the bag sensor 6 of the n+1th vibration conveyor section 100 to output a bag signal, causing its single-pole double-throw relay Q (n+1) The normally closed terminal Nc is connected to the common terminal com and the normally closed relay W is disconnected. (n+1) Disconnect, thereby cutting off the vibration exciter M corresponding to the nth vibration conveying section 100 (n) If the bagged goods are large enough to make the bag sensors 6 of the adjacent nth vibration conveyor section 100 and the n+1th vibration conveyor section 100 maintain bagged signals, then the nth vibration conveyor section 100 is still in the bagged state, and the exciter M corresponding to the nth vibration conveyor section 100 is (n) If the bag is small, only the bag sensor 6 of one vibration conveying section 100 can maintain the bag signal. At this time, the nth vibration conveying section is in the no-bag state. If the n-1th vibration conveying section 100 also has no bag, then its corresponding normally open relay P (n-1) Keep disconnected, the exciter M corresponding to the nth vibration conveying section (n) It is still in the disconnected state and does not vibrate. If the n-1th vibrating conveying section 100 has a bag, the operation process between these two adjacent vibrating conveying sections 100 is exactly the same as that between the nth and n+1th sections described above. The same logic applies to the remaining vibrating conveying sections 100 and will not be described in detail.
[0069] To make the fonts on the drawing clearly visible, Figure 8 In the figure, ellipsis is used to replace the circuits corresponding to the intermediate vibration conveying sections 100. (t) Section SPDT relay Q (t) The normally open end is connected to the counting mechanism control circuit.
[0070] Due to the vibration throwing and movement constraint of the groove-shaped carrier plate 1, the bagged goods 18 gather to the center of the carrier plate 1 and continuously eliminate the overlapping and parallelism in the jumping travel, and due to the sensing monitoring and orderly start-stop control of the circuit, the bagged goods 18 gradually automatically sort in the travel, with the rear bag constantly following the rear, forming a single-column single-bag longitudinal queue for continuous forward conveying.
[0071] If the reliability and durability of the control circuit are to be enhanced, the ordinary relays in the circuit can be replaced by solid-state relays.
[0072] As shown in Figure 9 , the embodiment is further provided with a counting mechanism 9 on the downstream side of the downstream-end vibration conveying section 100 and a disorderly stacking storage 13 on the upstream side of the upstream-end vibration conveying section 100, the counting mechanism 9 is connected with the controller 5 and is counted one by one by the sorting conveying control circuit of the counting control circuit of the controller 5. The counting control circuit can adopt various conventional circuits according to the structural principle and action process of different counting mechanisms, which is not expanded here.
[0073] In the embodiment, the counting mechanism 9 is composed of a movable slide plate 904, a counting sensor 902 and the base 4, as shown in Figure 9 , the movable slide plate 904 is a flat plate, the trailing edge of the movable slide plate 904 is placed below the leading edge of the front-end carrier plate 1 and is hinged on the base 4 through a hinge shaft 905, a tension spring 906 is arranged between the movable slide plate 904 and the base 4, so that the movable slide plate 904 keeps in contact with a push pin 907 arranged in parallel below; the push pin 907 is connected at one end of a crank 908, the other end of the crank 908 is connected with a driving motor 903, the driving motor 903 drives the crank 908 to rotate, drives the push pin 14 to push the movable slide plate 904 to rise and fall, and the counting sensor 902 is arranged on the base 4 corresponding to the lowered position of the leading edge of the movable slide plate 904.
[0074] Referring to Figure 9 , the working state of the counting mechanism 9 is shown, when the counting output is not needed, the push pin 907 is at the high point, supports the movable slide plate 9, so that the leading edge is higher than the trailing edge, is at the raised position, and the counting sensor 15 cannot sense the bagged goods 18, which is the standby state. Figure 10 To Figure 9 is a left view.
[0075] When the counting output is needed, the driving motor 903 is started, the push pin 907 is stopped at the low point with the crank 908, supports the movable slide plate 904 which is lowered, so that the leading edge of the movable slide plate 904 is lower than the trailing edge, is at the lowered position, as shown in Figure 11Meanwhile, the vibration conveying section 100 at the downstream end starts to vibrate to convey the bagged goods 18 to the movable slide plate 904 and quickly slide down to the output, and the counting sensor 902 below the movable slide plate 904 senses the bagged goods 18 and sends a counting signal to the controller 5, which is the state of sending, Figure 12 To Figure 11 the left view. When the bag number to be sent is reached, the vibration conveying section 100 at the downstream end stops vibrating while the driving motor 903 is started, the tumbler 907 is turned to the high point with the crank 908 to stop, and the front edge of the movable slide plate 904 is returned to the raised position, and the whole device returns to the standby state.
[0076] The embodiment also particularly provides a detection port 909 at the front end of the movable slide plate 904 which is matched with the counting sensor 902, and when the front end of the movable slide plate 904 is lowered, the counting sensor 902 is just below the detection port 909, and when the bagged goods 18 slide down along the movable slide plate 904, they pass through the detection port 909, and the counting sensor 902 can detect the bagged goods 18.
[0077] In actual application, the movable slide plate 904 can also be made of transparent material to ensure that the counting sensor 902 can detect the bagged goods 18. The counting sensor 902 is preferably a reflective light sensor.
[0078] The controller 5 can control the driving motor 903 to rotate a specific angle to lower the front edge of the movable slide plate 904 to a preset position when the bagged goods automatic sorting and conveying counting device is started, and control the driving motor 903 to reverse a specific angle to raise the front edge of the movable slide plate 904 to reset when the bagged goods automatic sorting and conveying counting device is turned off.
[0079] Figure 13 The bagged goods automatic sorting and conveying counting device provided with the above counting mechanism and the random pile storage bin 13 is shown. The random pile storage bin 13 is arranged above the first section, and the tail end of the groove of the carrier plate 1 of the first section is blocked. The bagged goods 18 are poured from the bottom of the random pile storage bin 13 to the carrier plate 1 of the vibration conveying section 100 of the first section to be stacked in a disordered state. The load of the vibration conveying section 100 below the random pile storage bin 13 is greater than that of other vibration conveying sections 100, so the power of the exciter M of the vibration conveying section 100 of the first section and the width and thickness of the vibration support 2 can be increased accordingly.
[0080] Vibration conveying has always been a suitable conveying method for irregular items. Under the action of the multi-vibration section conveying method in which each vibration conveying section 100 is independently controlled to vibrate, as long as the bagged goods are not very flat and thin and are not very easy to stack, the error rate of counting and output can be reduced to less than one thousandth, and the precision is higher for very irregular bags that are not easy to stack. Embodiment 2
[0081] There are many application occasions requiring small equipment footprint, so the structure of the conveying device must be as compact as possible, and the volume must be as small as possible. For example, there are hundreds of varieties of small-bagged traditional Chinese medicine decoction pieces. If automatic counting and dispensing are to be achieved, hundreds of small-bagged goods automatic sorting, conveying and counting devices must be integrated and operated, so compact design is very necessary.
[0082] Therefore, the present embodiment is further improved on the basis of Embodiment 1: 1) the single-layer straight-line arrangement of each vibration conveying section 100 is changed to a multi-layer folded-back arrangement to shorten the device length; 2) the vibration support 2 is changed from vertical arrangement to horizontal inclined arrangement to reduce the height of the vibration conveying section 100, and further reduce the overall height of the multi-layer folded-back arrangement; 3) a crank pin pop mechanism is used as the exciter M instead of the electromagnetic exciter in Embodiment 1 to adapt to small-space compact design, while also reducing the driving power; 4) the counting mechanism 9 is changed to a roller row type to adapt to small-space compact design; 5) the bag sensor 6 is changed to a beam-type photoelectric switch to adapt to small-space compact design; 6) the bag sensor 6 is increased to obtain higher output accuracy.
[0083] In the present embodiment, the multi-layer folded-back arrangement is to divide all the vibration conveying sections 100 into three sections, and then each section is stacked in three layers from top to bottom. Each layer still has a plurality of vibration conveying sections 100 arranged in sequence. The conveying directions of the vibration conveying sections 100 of adjacent two layers are opposite. Except for the lowermost layer, a side slide plate 8 is arranged at the downstream end of each layer. The side slide plate 8 is inclined to the vibration conveying section 100 at the upstream end of the adjacent lower layer. Any side slide plate 8 is located above the side of the vibration conveying section 100 at the upstream end of the lower layer. The side slide plate 8 extends downwardly and obliquely from the side of the vibration conveying section 100 at the downstream end of the same layer.
[0084] To improve the conveying efficiency, the width of the plurality of vibration conveying sections 100 of the uppermost layer is greater than that of the vibration conveying sections 100 of each of the lower layers. Except for the vibration conveying section 100 of the uppermost layer, the vibration conveying sections 100 of the remaining layers are arranged in a staggered manner in the width direction.
[0085] When the bagged goods 18 are conveyed downstream from the vibration conveying section 100 at the upstream end of the top layer to the vibration conveying section 100 at the downstream end of the layer, they are guided to the vibration conveying section 100 at the upstream end of the middle layer by the side slide plate 8, and are thus conveyed downstream in turn. The conveying directions of the vibration conveying sections 100 of adjacent two layers are opposite. The bagged goods 18 follow a back-and-forth path and are conveyed to the downstream end along the entire conveying device.
[0086] For example, the bagged goods 18 are conveyed downstream from the vibration conveying section 100 at the upstream end of the top layer to the vibration conveying section 100 at the downstream end of the layer, and are guided to the vibration conveying section 100 at the upstream end of the middle layer by the side slide plate 8. The bagged goods 18 are conveyed downstream in turn. The conveying directions of the vibration conveying sections 100 of adjacent two layers are opposite. The bagged goods 18 follow a back-and-forth path and are conveyed to the downstream end along the entire conveying device. Figure 14 and Figure 15The illustrated bagged goods automatic sequencing conveying and counting device conveys bagged goods 18 (small bagged Chinese herbal pieces) as an example: the total vibration conveying section 100 is 13 sections, which is divided into three sections and arranged in three layers from top to bottom, the first section is 5 sections, of which the first and second sections correspond to the connection of the random pile storage bin 13, the second and third sections are each 4 sections, and the thirteenth section (the last section) corresponds to the connection of the counting mechanism 9. The two folding back parts of the upper and middle layers are respectively provided with side slides 8 to horizontally slide the bags to the first section of the lower layer, so as to form a parallel staggered three-layer space structure, see Figure 14 , Figure 15 , In order to observe the folding back condition, only the arc-shaped cross-section of the carrier plate 1 and the side slide 8 is shown in the figure, and the remaining parts are omitted.
[0087] The structure and installation method of the transversely inclined vibration support 2 are shown in Figure 16 . The transverse direction refers to the connection point of the vibration support 2 and the base 4 on one side of the carrier plate 1, so that the entire vibration support 2 is in a cantilever beam state, and the inclination refers to the normal line of the vibration support 2 and the bottom plane of the carrier plate 1 still forming an angle α. The position where the vibration support 2 in embodiment 1 is connected to the base 4 is directly below the carrier plate 1. Compared with embodiment 1, the vibration section height of the present embodiment is reduced, and the total height of the three layers of the multi-layer folding type arrangement is also reduced. Since the vibration support 2 in the present embodiment still maintains an inclined state, the vibration direction is still the direction of the normal line of the vibration support 2 plane and the bottom of the carrier plate 1, and the angle α in the present embodiment is the same as that in embodiment 1. Therefore, the vibration trajectory of the carrier plate 1 is the same as that in embodiment 1, and the same horizontal movement of 20° oblique up and down is performed.
[0088] The crank handle pin pop mechanism in the present embodiment as the excitation vibrator M has the same structure as the driving device for driving the movable slide plate 904 in embodiment 1, which drives the crank 908 and the handle pin 907 through the driving motor 903. The handle pin 907 corresponds to the lug plate 7 arranged on the bottom surface of the carrier plate 1, see Figure 16 , In the figure, the lug plate 7 is made in one piece with the vibration support 2 and is tightly connected with the carrier plate 1. The excitation process is shown in Figure 17: Static start, the dial pin 907 in the process of rotating with the crank 908 touches and starts to dial the ear plate 7 at position a, and is detached from the ear plate 7 at position b, thus generating the elastic dialing effect. After the dial pin 907 is detached from the ear plate 7, the vibration exciter M has no contact with the carrier plate 1, and the vibration support 2 after being elastically dialed enters the damped free vibration state, and the carrier plate 1 vibrates, the dotted arrow in the figure is the vibration trajectory of the carrier plate 1, and the length of the arrow is the maximum amplitude of the end of the carrier plate 1. The crank 908 continues to rotate, and the free vibration of the vibration support 2 is attenuated during the period from the detachment to the re-touching of the ear plate 7 by the dial pin 907, and the vibration is restored after the dial pin 907 is elastically dialed again. In terms of small-bagged traditional Chinese medicine decoction pieces, the elastic dialing type vibration excitation of 2-3 times per second (i.e. 2-3 Hz) is sufficient to maintain the continuous vibration of the carrier plate 1. Since the free vibration frequency of the carrier plate 1 is much higher than 2-3 Hz, the position where the dial pin 907 re-touches the ear plate 7 after starting the vibration is not randomly at any point on the vibration trajectory, but is close to the front end of the dotted arrow. The touch point from the front end of the dotted arrow to position a is the vibration stopping process of the dial pin 907 to the remaining vibration of the carrier plate 1, and this process only lasts for a moment, and the elastic dialing vibration process starts again at the starting elastic dialing point position a. Therefore, position a is both the static stop position and the midpoint of the vibration trajectory, and is also the starting elastic dialing point of each vibration restoration. Adjusting the distance between the driving motor 903 and the ear plate 7 or changing the rotation radius of the dial pin 907 can adjust the elastic dialing force or amplitude, and the direction of the elastic dialing has no limitation, which can be clockwise dialing to the rear detachment as shown in Figure 16 Figure 17 , or counterclockwise dialing to the front detachment as shown in Figure 18 . Increasing the rotation speed of the driving motor 903 and driving it with a low-frequency pulse width modulation power supply can also help to enhance the elastic dialing force, and a stepper motor can also be used, which is started and elastically dialed at position c in Figure 17 , and then stopped at position c after the elastic dialing, so as to obtain the more ideal effect of rapid start and fast dialing, and the frequency of the elastic dialing is adjusted as required. Position c is the empty position which does not interfere with the free vibration of the carrier plate 1.
[0089] Compared with the electromagnetic type vibration exciter M shown in embodiment 1 which forces continuous vibration, the elastic dialing type vibration exciter M shown in the embodiment vibrates freely most of the time, has a smaller volume, can meet the installation requirement of low height, and has relatively small power consumption. Further, the dial pin 907 is rotatably arranged on the crank 908, and the outer surface of the dial pin 907 is covered with glue (the dial pin 907 shown in Figure 16 , 17 , 18 is a glued dial pin), and an elastic pad 20 is arranged at the contact position between the dial pin 907 and the ear plate 7, so that the dial pin 907 and the ear plate 7 become rolling contact, which can reduce noise and prolong the service life.
[0090] The counting mechanism 9 described in this embodiment is of roller type, including multiple rows of horizontal conveying rollers 901 arranged in parallel along the conveying direction, counting sensors 902 and a drive motor 903. The drive motor 903 drives the horizontal conveying rollers 901 to rotate to drive the bagged goods thereon to move downstream. The counting sensors 902 are arranged on the downstream side of all horizontal conveying rollers 901 to count the bagged goods passing over the counting sensors 902.
[0091] The horizontal conveying roller 901 is driven by a driving motor 903 via a belt or gear. Figure 14 The simplified drawing in the middle shows the structure of the counting mechanism. When counting output is not required, the horizontal conveyor roller 901 is stationary and in a standby state. When counting output is required, the drive motor drives the horizontal conveyor roller 901 to rotate. At the same time, the downstream vibrating conveyor section 100, i.e., the 13th section, starts vibrating, sending the bag to the rotating horizontal conveyor roller 901, where it is immediately and rapidly output. The reflective counting sensor 902 below the front horizontal conveyor roller 901 senses and sends a counting signal, indicating the output state. When the number of bags to be output is reached, the horizontal conveyor roller 901 stops, and the entire device returns to a standby state. Compared with the counting mechanism 9 described in Example 1, the use of the horizontal conveyor roller 901 to output the bagged goods 18 requires a smaller installation height, which can meet the installation requirements of low sections.
[0092] like Figure 27 The figure shows the control circuit of the counting mechanism 9 and the sorting and conveying control circuit of this embodiment. The driving motor 903 is connected in parallel to the downstream end of the vibration exciter M. (t) Downstream, one end of the drive motor 903 is connected to one pole of the power supply, and the other end of the drive motor 903 is connected to the other pole of the power supply through relay P903 to form a loop, and connected to relay Q through relay W903. (t) Normally open terminal No. When the downstream end exciter M (t) If there is a bag on it, controller 5 will control relay Q (t) Connect relay W903 and close relay P903 to make the downstream end exciter M (t) Start, and convey the bagged goods to the counting mechanism 9. At the same time, the driving motor 903 rotates and drives the bagged goods 18 to pass through the counting sensor 902. In order to ensure that the bagged goods 18 on the technical mechanism 9 are counted and output, the relay P903 can be controlled in a delayed disconnection mode. When the downstream end exciter M (t) If there is no bag on the bag, the controller 5 controls the relay 903 to disconnect after a delay of a period of time. In actual application, the user can also choose to keep the relay P903 closed during the startup phase of the bagged goods automatic sorting, conveying and counting device.
[0093] like Figure 19As shown, the bag sensor 6 in the embodiment is a pair of photoelectric switches, including a light projector 601 and a light receiver 602, which are respectively arranged on both sides of the conveying direction of the carrier plate 1. The light projector 601 is inclined towards the upper surface of the carrier plate 1, so that the light beam emitted by the light projector 601 is reflected by the carrier plate 1 and then enters the light receiver 602.
[0094] Although the reflective photoelectric switch is easy to install, it is easily disturbed by the light environment inside the device, especially in a small and compact device. The signal stability is not enough and it is not easy to adjust. Therefore, the pair of photoelectric switches, which are not disturbed by the light environment inside the device and are easy to adjust, are used in the embodiment. The light projector 601 and the light receiver 602 are used as a pair. The pair of photoelectric switches are used to detect the bagged goods 18 in the groove of the carrier plate 1 with an arc or trapezoidal cross section, especially the bagged goods 18 with a thin thickness. If the straight light path installation method is used, in which the light projector 601 directly faces the light receiver 602, it is easy to miss the detection. The solution adopted in the embodiment is the multiple reflection method. First, the light-reflecting material is used, i.e. the smooth plastic plate, aluminum plate or stainless steel plate with good light-reflecting properties is used to manufacture the carrier plate 1 with an arc or trapezoidal cross section. Second, the half-beam light is used to enter the groove, i.e. half of the light beam of the light projector 601 is projected into the groove of the carrier plate 1. In theory, the light beam emitted by the light projector 601 is a circular cone with an angle of β. However, the light receiving lens of the light receiver 602 corresponding to the light projector 601 is only a small dot. Therefore, the projected light beam that can enter the light receiving lens can be approximately considered to exist only in the area of the isosceles triangle with an angle of β. The equal sides of the isosceles triangle are the outermost edges of the light beam, which can be called a light projection triangle. The half-beam is a β / 2 half of the light projection triangle divided by the median.
[0095] The actual installation method of the half-beam light entering the groove is as follows: the light projector 601 and the light receiver 602 are respectively installed on both sides of the carrier plate 1. The positions of the light projector 601 and the light receiver 602 are symmetrical and both are inclined towards the inner bottom surface of the groove of the carrier plate 1. Only the upper half of the light beam of the light projector 601 is projected into the groove, and the outermost edge of the light beam does not cross the center line of the groove. In this way, the light beam emitted by the light projector 601 can be as close to the groove bottom as possible and enter the light receiving lens of the light receiver 602 after multiple reflections. See Figure 19 、 Figure 20The bag sensor 6 is applied to the arc-shaped groove and the trapezoidal groove. The small narrow beam shown by the thin solid line in the projected light beam reaches the light receiver 602 after two reflections on the bottom surface of the arc-shaped groove and three reflections on the bottom surface of the trapezoidal groove. The rest is invalid scattered light, which is irrelevant to the detection result. As can be seen from the figure, the effective light path reaching the light receiver 602 almost passes along the inner surface of the groove of the object plate 1. The thin bagged goods 18 can block the light path, generating a certain bag signal. Therefore, the ideal light path between the light projector 601 and the light receiver 602 of the opposite type photoelectric switch applied to the arc-shaped and trapezoidal cross-section groove is a broken line-shaped curved light path with multiple reflections on the bottom surface of the groove.
[0096] As shown in Figure 21 , Figure 22 , as a further improvement of the above technical solution, the embodiment can further add one bag sensor 6 between every two bag sensors 6 of at least one downstream vibrating conveying section 100, and connect the added bag sensor 6 in parallel with the original bag sensor 6 corresponding to the upstream adjacent vibrating conveying section 100, that is, two bag sensors 6 are arranged corresponding to the upstream adjacent vibrating conveying section 100. Thus, the detection range of the bag sensor 6 corresponding to a vibrating conveying section 100 is expanded to the downstream vibrating conveying section 100. In this way, the control result generated is that a bagged goods 18 that has been sent from the vibrating conveying section 100 to the downstream conveying section 100 can still be detected by the bag sensor 6 corresponding to the vibrating conveying section 100, so that the upstream adjacent vibrating conveying section 100 cannot supply bags to the vibrating conveying section 100 that has actually no bags, for example, a bagged goods 18 has left the 11th vibrating conveying section 100 and arrived at the 12th vibrating conveying section 100, but the bag sensor 6 of the 11th vibrating conveying section 100 still feeds back the signal of detecting the bagged goods 18. Therefore, according to the control mechanism described in Embodiment 1, the 10th vibrating conveying section 100 cannot supply bags to the 11th vibrating conveying section 100 that has actually no bags. The queue of bagged goods 18 becomes an interval type queue with one bag in one section, which is beneficial to maintaining the safe counting bag distance and more reliably ensuring the uniqueness of the bags output by the counting mechanism 9, so as to achieve higher counting output accuracy, and the error rate of the counting output can reach tens of thousands of a percent.
[0097] In addition to the above improvements, the embodiment can also connect a normally closed relay V Figure 8 between the nth single-pole double-throw relay Q (n) and the normally open relay P (n-1) in the circuit shown in (n+1) . (n+1) , t>n>1, the normally closed relay V (n+1) and the normally closed relay W (n+1)Synchronous action. In this way, a certain vibrating conveying section 100 and its adjacent downstream vibrating conveying section 100 are associated as the same section in the circuit, so that the bag on the n-1 vibrating conveying section 100 can only be powered on and vibrated to supply bags to the n vibrating conveying section 100 when there are no bags on both the n vibrating conveying section 100 and the n+1 vibrating conveying section 100. The control effect is the same as that of adding a bag sensor 6, and it can also generate an interval type queue with one section having bags and the other without bags, such as Figure 26 shown.
[0098] In summary, the compact automatic sorting, conveying and counting device for bagged goods improved by the technology of this embodiment can achieve the purpose of small size and high precision. Its design overview is: it is configured with a folding segment, a horizontal vibration support 2, a plucked vibration, a roller row counting, a density-enhancing through-beam bag sensor 6 and its MCU controller 5, see Figure 21 、 Figure 22 In actual applications, the width of the random stacking bin 13 is larger than the width of the loading plate 1 , and the upper, middle, and lower layers of the vibrating conveying sections 100 need to be staggered left and right. Therefore, in this embodiment, the upper layer of the loading plate 1 is widened to completely cover the middle and lower layers of the vibrating conveying sections 100 and match the width of the random stacking bin 13 .
[0099] The working principle and control process of this embodiment are the same as those of embodiment 1, so they will not be described in detail. Example 3
[0100] A plurality of the aforementioned bagged goods automatic sorting devices 200 are stacked vertically and arranged side by side horizontally to form a wall matrix, which can realize the functions of simultaneously bagging multiple varieties and quickly picking and placing orders. Therefore, based on the bagged goods automatic sorting, conveying and counting device 200 described in the above embodiment 2, this embodiment provides a bagged goods automatic picking machine, such as Figures 23-25As shown, the bagged goods automatic picking machine comprises a rack 10, the front of which is provided with a plurality of horizontally arranged mounting slots 11, the horizontally arranged mounting slots 11 form openings on the front end surface of the rack 10, and the tail of the rack 10 is provided with a plurality of obliquely arranged mounting slots 12 corresponding to the horizontally arranged mounting slots 11 and communicating with each other, the obliquely arranged mounting slots 12 extend obliquely upwards and rearwards from the tail of the horizontally arranged mounting slots 11, the bagged goods automatic sorting and conveying counting device 200 described in Embodiment 2 is plug-in mounted in any horizontally arranged mounting slot 11, and a random storage bin 13 is plug-in mounted in any obliquely arranged mounting slot 11, the storage outlet 14 at the lower end of the random storage bin 13 is located above the upstream end vibration conveying section 100 of the bagged goods automatic sorting and conveying counting device 200, a coaming 16 is connected to the downstream end base 4 of the bagged goods automatic sorting and conveying counting device 200, a bagging drop opening 15 is formed between the coaming 16 and the counting mechanism 9 of the bagged goods automatic sorting and conveying counting device 200, the bagging drop openings 15 of the bagged goods automatic sorting and conveying counting devices 200 in the same column and multiple layers on the rack are stacked one above another, forming a bagging drop channel extending from top to bottom, and a collecting device 17 is arranged below the bagging drop channel in the arrangement direction of the bagging drop channels, the collecting device 17 in the embodiment is preferably a conveyor, which is used to collect the bagged goods output by the bagged goods automatic sorting and conveying counting device 200.
[0101] In actual application, the collecting device 17 can be one or a combination of conveyors, chutes, pushers and collection hoppers. For example, a chute or a collection hopper can be used to collect and guide the bagged goods to the collecting device 17, and then the bagged goods are output through the collecting device 17, or the bagged goods can be guided into a packaging bag by a chute or a collection hopper, or after the bagged goods fall on a platform, a pusher is used to push the bagged goods into a packaging bag or a collection hopper.
[0102] The space occupation height and width of the bagged goods automatic sorting and conveying counting device 200 are preferably consistent with the space occupation height and width of the random storage bin 13, so as to obtain the highest possible space utilization.
[0103] The working mode and process of the above-mentioned bagged goods automatic picking machine: each random storage bin 13 is a minimum inventory unit (SKU) of a variety, and the controller 5 of the bagged goods automatic sorting, conveying and counting device 200 corresponding to the bin is connected to the communication network of the general control computer.
