[0002] The process of an automated goods circulation warehouse is generally warehousing, picking and delivery, and in this series of processes, logistics containers are used as storage and circulation units. In a three-dimensional warehouse using logistics containers as storage units, when warehousing, picking and delivery are performed, conveying lines and rollers are mainly used to convey logistics containers to the location of the picking personnel, and then complex mechanisms are used to horizontally move, lift or tilt the logistics containers, and then manual picking is performed. With the development of the times, various goods trade has gradually flourished, and the circulation of goods has become increasingly large, and traditional manpower has been unable to solve the current goods sorting, so mechanical goods circulation and sorting devices have emerged as the times require, and they have the characteristics of continuous and large-scale circulation. For example, a goods sorting device is disclosed in Chinese Patent No. CN209577439U, which was published on November 5, 2019, and has the characteristics of high circulation efficiency and accurate classification. The main conveying belt output end is provided with a large goods collection box, a plurality of auxiliary conveying belts are arranged vertically to the main conveying belt, the auxiliary conveying belts are connected to the main conveying belt through a weighing device and are arranged on the same side of the main conveying belt, a first pushing device is arranged on the side of the main conveying belt opposite to the auxiliary conveying belts, and a second pushing device is arranged on the side of the auxiliary conveying belts opposite to each goods collection box. However, the main and auxiliary conveying belts of the utility model both need double-circulation chains or roller structures, and the structure is relatively complex and the manufacturing cost is high. SUMMARY

[0003] 1. Technical problem to be solved by the application

[0004] The present application aims to solve the problem of the need for double-circulation chains or roller structures in the prior art conveying device for goods circulation, and provides an intermittent reciprocating slider based on a single roller chain. The horizontal circulation chain can be rotated, and the driving wheel and the driven wheel rotating with the circulation chain are used to drive the upper roller on the slider as a driving wheel to drive the goods on the slider to circulate. When the circulation chain moves horizontally, the slider can remain stationary, and the motor does not need to be frequently started and stopped to provide sufficient time for loading and unloading goods. The structure is simple and the circulation efficiency is high.

[0005] 2. Technical solution

[0006] To achieve the above-mentioned purpose, the technical solution provided by the present application is as follows:

[0007] The application discloses a single-roller chain-based intermittent reciprocating slider, which comprises a driving wheel and a driven wheel which are linked through a horizontally arranged circulating chain, a steering wheel for steering the circulating chain, and N pairs of guide wheels for guiding left chain segments of the circulating chain to N levels, wherein if there are three levels, three pairs of guide wheels are needed; an upper surface of the circulating chain is fixedly connected with a horizontally arranged upper roller through a connecting shaft; the upper roller is inserted into a rectangular sliding groove at the bottom of a slider above the upper roller, and the upper roller is a driving wheel.

[0008] Further, the upper roller is one, and when the volume of the goods is large, for example, larger than the width of the two sides of the circulating chain, the goods driven by multiple upper rollers are prone to interference, and the upper roller is one, which drives the circulation of single goods, thereby avoiding the interference; the steering wheel is a left steering wheel and a right steering wheel which are symmetrically arranged on the left and right sides of the circulating chain; the guide wheel is an inner guide wheel and an outer guide wheel which are symmetrically arranged on the inside and outside of the left chain and are arranged in pairs, and the inner guide wheel and the outer guide wheel can be multiple pairs; if the goods need to be intermittently stopped N times in the running direction, (N-1) pairs of inner guide wheels and outer guide wheels are needed, and of course, the left steering wheel and the right steering wheel can also be understood as the last pair of inner guide wheels and outer guide wheels.

[0009] Further, the circulating chain is laid on a support platform to play a role in protecting the chain; a motor for driving the driving wheel and support platforms for supporting the driven wheel, the steering wheel and the guide wheel are all fixed below the support platform, and the height of the motor and the support platforms is consistent as much as possible.

[0010] Further, the support platform is an annular groove which is adapted to the rotating area of the circulating chain, so that the circulating chain rotates in a limited area and plays a certain protective role on the chain.

[0011] Further, the upper roller is fixedly connected to the upper surface of one link of the circulating chain, and if the upper roller is fixed between two links, interference and wheel jamming will occur when the circulating chain moves to the sprocket, thereby achieving the technical effect of avoiding wheel jamming; the width of the sliding groove is adapted to the diameter of the upper roller, so that the upper roller slides in a limited area, avoids interference force and can protect the upper roller.

[0012] Further, the upper roller is tightly fitted or key-connected tightly fitted sleeve on the connecting shaft, and the tightly fitted or key-connected tightly fitted sleeve can avoid the problem of the upper roller being out of the shaft due to the need of the upper roller to bear the weight; the lower surface of the circulating chain is fixedly connected with the lower roller, so that sliding friction is changed into rolling friction, thereby improving the working efficiency and supporting the chain.

[0013] Further, the upper roller and the lower roller are bearings, and the rolling friction generated by the bearings is smaller than that generated by other types such as rubber wheels and plastic wheels.

[0014] Further, the bearing sleeve of the bearing is sleeved with an axle retainer, and the horizontal bearing needs to avoid the invasion of impurities.

[0015] Further, the vertical section of the sliding groove is in the shape of T, so that the sliding block can be prevented from being dislocated when the goods are taken out.

[0016] Further, the goods are placed on the sliding block and are delivered in a circulating assembly line, and can be delivered to any position outside the circulating motion area generated by the circulating chain.

[0020] (2) The intermittent reciprocating sliding block based on the single-roller chain divides the left chain into N stages by N pairs of guide wheels, and the left steering wheel and the right steering wheel are regarded as the guide wheels farthest from the circulating chain; when the upper roller moves horizontally, the upper roller rolls horizontally in the sliding groove, and at this time, the sliding block remains stationary; if there are N stages, there are N short intermittent stops, and when the circulating chain returns, there is one long intermittent stop, so that the motor does not need to be frequently started and stopped to provide sufficient time for loading and unloading; in theory, under the premise of uniform motion of the circulating chain, the time of the long intermittent stop is the sum of the times of the N short intermittent stops.

DETAILED DESCRIPTION

[0038] In order to further understand the content of the present application, the present application is described in detail in combination with the drawings and embodiments.

[0039] Embodiment 1

[0040] The single-roller chain-based intermittent reciprocating slider according to the embodiment includes a driving wheel 15 and a driven wheel 16 linked by a horizontally placed circulating chain 11, steering wheels for steering the circulating chain 11, and N pairs of guide wheels for guiding the left chain section of the circulating chain 11 to N levels. If there are three levels, three pairs of guide wheels are needed. The upper surface of the circulating chain 11 is fixedly connected with the horizontally placed upper roller 12 through the connecting shaft 3. The upper roller 12 is inserted into the rectangular sliding groove 181 at the bottom of the slider 18 above it, and the upper roller 12 is the driving wheel.

[0041] In specific use, the driving wheel 15 and the driven wheel 16 driven by the motor are generally the driving sprocket and the driven sprocket, and the circulating chain 11 moves in a circulating manner in a tensioned state. The upper roller 12 on the circulating chain 11 serves as the driving wheel to drive the goods on the slider 18 to circulate in a horizontal state. The slider 18 carrying the goods cooperates with the upper roller 12 to avoid interference in any direction in the horizontal state of the slider 18. When the circulating chain 11 drives the upper roller 12 to move horizontally, the upper roller 12 rolls in the sliding groove 181, and at this time, the slider 18 remains stationary, such as Figure 1As shown, it can be 3 stages, then there are 3 short intermittent pauses, respectively, Ⅰ intermittent section Ⅱ 200, intermittent section Ⅲ 300 and intermittent section 400, at the most recent end, the lower end of the circulating chain in the figure is a long intermittent section 500, and it is a long intermittent pause when it circulates back. Without frequent start and stop of the motor, enough time is provided for loading and unloading. In theory, under the premise of uniform motion of the circulating chain 11, the time of one long intermittent pause is the sum of the times of N short intermittent pauses, and the time of the short intermittent pause is not necessarily the same, which is related to the length of the section. In theory, as long as the supporting force of the circulating chain 11 and the upper roller 12 is large enough, multiple sliding blocks 18 can be provided. Due to the cooperation of the upper roller 12 and the circulating chain 11, the upper roller 12 can rotate at any angle in the horizontal direction, and the sliding block 18 also rotates, thereby eliminating the interference caused by the collision.

[0042] Embodiment 2

[0043] The intermittent reciprocating sliding block based on single roller chain of the present embodiment has the same basic structure as embodiment 1, and the difference or improvement is that: Figure 1 、 2 As shown, the upper roller 12 is single, when the volume of the goods is large, and the length of the sliding block 18 is large, which is greater than the width of the circulating chain 11 on both sides, the sliding blocks 18 driven by multiple upper rollers 12 are prone to interference that cannot be eliminated by the upper roller 12. The upper roller 12 is one, which drives a single sliding block 18 to drive the flow of goods, thereby avoiding interference. The steering wheels are left steering wheel 13 and right steering wheel 14 which are symmetrically arranged inside the circulating chain 11; the guide wheels are inner guide wheels 17 and outer guide wheels 19 which are symmetrically arranged inside and outside the left chain and are arranged in pairs, and the inner guide wheels 17 and the outer guide wheels 19 can be multiple pairs. In the running direction of the goods, if intermittent pause is needed N times, (N-1) pairs of inner guide wheels 17 and outer guide wheels 19 are needed, that is, if intermittent pause is needed 3 times, 2 pairs of inner guide wheels 17 and outer guide wheels 19 are needed, of course, the left steering wheel 13 and the right steering wheel 14 can also be understood as the last pair of inner guide wheels 17 and outer guide wheels 19. The circulating chain 11 is laid on the support platform 7, which plays a role in protecting the chain; the motor 20 driving the driving wheel 15, and the support platform 21 supporting the driven wheel 16, the steering wheel and the guide wheel are all fixed below the support platform 7, the height of the motor and the support platform is as consistent as possible, of course, if the goods need to be delivered to a certain height, the height of part of the support platform 9 can also be greater than the motor 17. The upper roller 12 and the sliding block 18 are both single, the sliding block 18 carries the goods, cooperates with the upper roller 12, the upper roller 12 can rotate at any angle in the horizontal direction to eliminate interference, the upper roller 12 drives the sliding block 18 to move linearly, and the sliding block 18 remains unchanged.

[0044] The application of the intermittent reciprocating sliding block based on single roller chain of the present embodiment is as follows:

[0045] S1, placement: the circulating chain 11 drives the slider 18 to run in the long intermittent section 500, that is Figure 1 the bottom end, the goods are placed one by one on the slider 18, and because the intermittent period is long, a large number of goods can be placed;

[0046] S2, taking goods: when the circulating chain 11 drives the slider 18 to run to the I intermittent section 200, part of the goods are taken; when the slider 18 runs to the II intermittent section 300, part of the goods are taken; when the slider 18 runs to the III intermittent section 300, part of the goods are taken, and the future and taken goods are run again to the long intermittent section 500 by the circulating chain 11;

[0047] S3, circulation: repeat the above steps to transfer the goods to the I intermittent section 200, the II intermittent section 300 and the III intermittent section 300 respectively, when the inner guide wheel 17 and the outer guide wheel 19 are three pairs, they can also be transferred to the IV intermittent section, and so on. According to the needs, any number of pairs can be set.

[0048] The intermittent reciprocating slider based on single roller chain of the embodiment, under the synergistic action of the circulating chain 11 circulating movement, the upper roller 12 can offset interference and the slider 18 can carry goods, is applied to the assembly line transmission of materials, and is transferred to any position 5 in the horizontal direction, the transmission is stable, the structure is simple, the transmission efficiency is high, and the motor 20 does not need to be frequently started, so that enough time is provided for taking goods in the intermittent period.

[0049] Embodiment 3

[0050] The intermittent reciprocating slider based on single roller chain of the embodiment, the basic structure is the same as that of embodiment 2, and the difference or improvement is that, as shown in the figure, the support platform 7 is an annular groove adapted to the rotating area of the circulating chain 11, so that the circulating chain 11 rotates in the defined area, and plays a certain protection role on the chain. As shown in Figure 3 , Figure 5 , 6 , 7, 8, 9, the upper roller 12 is fixedly connected to the upper surface of one of the chain links 100 of the circulating chain 11, and if it is fixed between two chain links 100, interference and wheel jamming will occur when the circulating chain 11 moves to the arc area of the driving or driven sprocket, thereby achieving the technical effect of avoiding wheel jamming. The structure of the chain link 100 is a prior art, as shown in Figure 8 , 9 , 10, which is connected by two joint connecting plates 101 and two joint connecting rods 102, and the chain links 100 are connected together by the open pin 103.

[0051] Embodiment 4

[0052] The intermittent reciprocating slider based on single roller chain of the embodiment has the same basic structure as that of embodiment 3, and is different or improved in that the upper roller 12 is tightly fitted or key-connected tightly fitted on the connecting shaft 3. Since the upper roller 12 needs to bear weight, the tight fitting or key-connected tightly fitted connection can avoid the problem of the upper roller 12 being disengaged from the shaft in the state of bearing weight. The upper roller 12 is preferably a bearing upper roller, and the rolling friction generated by the bearing is the smallest compared with other upper rollers such as rubber wheels and plastic wheels. Figure 4 、 7 , as shown in FIG. 8, the bearing sleeve of the bearing is sleeved with an axle retainer 121, and the horizontal bearing needs to avoid the intrusion of impurities. Figure 1 、 10 , as shown in FIG. 11, the bottom of the slider 18 is provided with a sliding groove 181 with a diameter matching that of the upper roller 12, so that the upper roller 12 slides in a limited area, avoids interference, and can protect the upper roller 12.

[0053] Embodiment 5

[0054] The intermittent reciprocating slider based on single roller chain of the embodiment has the same basic structure as that of embodiment 4, and is different or improved in that the bearing is embeddedly inserted into the slider 18 above the bearing, cooperates with the bearing, and can avoid interference in any direction in the horizontal state. More importantly, when the slider 18 is driven to move linearly under the driving of the circulating chain 11, the bearing does not normally move in the sliding groove 181 of the slider 18 at this time, and when the bearing is driven to move in an arc under the driving of the circulating chain 11, that is, when the bearing moves to the semicircular area at both ends of the circulating chain 11, the bearing moves in the sliding groove 181 to transmit the driving force of the circulating chain 11. Figure 10 、 11 As shown in FIGS. 14 and 15, the shape of the sliding groove 181 is square or waist-shaped, and the vertical section is “T”-shaped. When the required movement area of the upper roller 12 is large, such as when the length of the goods is greater than the width of the circulating chain 11, the sliding groove 181 is designed to be square. When the movement area of the upper roller 12 is small, such as when the length of the goods is smaller than the width of the circulating chain 11, the sliding groove 181 can be designed to be circular. The vertical section is “T”-shaped, which can avoid dislocation of the slider 18. The lower surface of the circulating chain 11 is fixedly connected with the lower roller 4. The lower roller 4 can be horizontal or vertical. When the lower roller 4 is horizontal, it rolls on the inner side wall of the supporting platform 7. When the lower roller 4 is vertical, it rolls on the surface of the supporting platform 7. The sliding friction is changed into rolling friction, which improves the working efficiency and also supports the chain.

[0055] Embodiment 6

[0056] The intermittent reciprocating slider based on single roller chain of the embodiment has the same basic structure as that of embodiment 5, and is different or improved in that Figure 12As shown, the inner guide wheel 17 of the I intermittent section 200 can be omitted, that is, the driving wheel 15 can play the role of the inner guide wheel 17 of the I intermittent section 200, and also play the role of guiding without affecting the circulating rotation of the circulating chain 11.

[0057] The above description of the present application and its embodiments is illustrative and not restrictive, and the embodiments shown in the drawings are only one of the embodiments of the present application, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired thereby, without departing from the spirit of the present application, similar structural modes and embodiments can be designed without creativity, which should belong to the protection scope of the present application.
