Description

TECHNICAL FIELD

[0001] The present application belongs to the field of automatic production technology, in particular to the field of full-automatic loading and stacking machine for marking and bagging parts of general freight train. BACKGROUND

[0002] The loading and stacking of marking and bagging parts is indispensable in the fields of agriculture, industry and commerce. At present, the intelligent filling and marking process of bulk granular bagging parts has been popularized in various industries, but the intelligent mechanical stacking of marking and bagging parts on freight trains is rarely implemented in China, especially in the small and medium-sized industry. More often, workers carry the marking and bagging parts on their shoulders and arms. The reason is that although many intelligent machines related to loading and stacking have been developed, they are not enough, such as many pallet stacking machines, which are still outside the process and need the cooperation of forklifts and workers to load the bagging parts on the freight train. Second, the structure is complex, the machine body is large, the cost of purchasing the machine is high, and the site requirement is large. For example, the patent documents CN201210248968.7, CN201320209013.0, CN201320451868.4, CN201610768964.X and many other machines not only limit the implementation of medium and small entities, especially the owners of agricultural and grain purchasing industry, but also limit many large production lines in terms of site. Therefore, the present application proposes a "freight train marking and bagging parts intelligent feeding machine", which is simple in structure, fast in speed, low in cost and does not occupy space, and meets the needs of various industries for the loading and stacking of "marking and bagging parts" of freight trains.

[0024] Figure 2 The component schematic diagram of the package control device in the truck package marking intelligent delivery machine according to the specific embodiments of the present application is shown in FIG. 1. Figure 2 As shown in FIG. 1, the package transmission system includes the following structures.

[0025] The package transmission system includes a package transmission belt 2, an eight-shaped package control device 1, and a package detection camera 3. Figure 1 The eight-shaped package control device is two arc-shaped box bodies installed in an eight-shaped open symmetry on the left and right frames of the package transmission belt and can be adjusted up and down. The box frame 10 is installed on the edge frame of the package transmission belt through a loose joint 12. The lower end of the curved slide plate (plastic or metal) 11 is fixed to the lower end of the box frame 10, and the upper part is connected to the telescopic rod of the push cylinder (also can use electromagnetic valve) 13. The cylinder body seat is installed on the box frame. The package detection camera (photoelectric switch) 14 is installed in the package control device box and can detect the package through the circular (square) opening on the curved slide plate. Figure 2

[0026] ​The function and principle of the bag piece controller: straighten the bag piece to make it more parallel and centered with the belt; set the output time difference of the front and rear two bag pieces on the transmission belt = S ≥ the time for the bag piece totem code basket 4 to code the four bag pieces in the basket and place them in the carriage and then return to the bag piece blocking position (bag piece transmission belt output port). When the switch 14 finds that the time difference between the next bag piece and the previous bag piece is less than the set value S, the push cylinder starts, the two curved slides are squeezed in the middle and clamp the bag piece, making the bag piece slide on the belt for a short time, and when the time difference between the next bag piece and the previous bag piece reaches the set value S, the push cylinder retracts and the clamped bag piece is released. The distance L (see Figure 1 ) from the bag piece discovery lens 14 to the belt output end can be adjusted by adjusting the position of the bag piece controller, L ≥ V * S (the belt linear speed = V, see Figure 3 ).

[0027] The bag piece transmission system includes the start and stop program setting of the bag piece transmission belt 2: when there are bag pieces in the totem code baskets A4 and B4, the "basket discovery" A19 and B19 (see Figure 3 、 Figure 8 ) will feed back the signal to the control system, which is defined as "basket saturation". When there is no bag piece in any of the totem code baskets A4 and B4 (it has been placed), the "basket discovery" A19 or B19 will feed back the signal to the control system, which is called "basket waiting". When the bag piece totem code system is in "basket waiting", the bag piece transmission system "supply discovery" 14 will normally operate whether it discovers a bag piece or not. When the bag piece totem code system is in "basket saturation" state, i.e. there are bag pieces in both totem code baskets A4 and B4, the bag piece transmission system "supply discovery" 14 will immediately stop the belt operation as soon as it discovers a bag piece (which means that there is a possibility that the totem code basket 4 cannot respond in time when the bag piece discovered by the transmission belt arrives at the transmission port). After one of the totem code baskets A4 and B4 places the bag piece (basket waiting), the bag piece transmission belt will restart. This program can be defined as: "basket waiting + supply discovery = belt operation; basket saturation + supply discovery = belt stop".

[0028] The bag piece transmission system includes the bag piece totem and totem technology, which realizes the accurate blocking and stable totem of the bag piece totem code basket 4 to the bag piece transmission belt 2, which is an important technical link of the bag piece intelligent totem machine of the truck, and is also a simple and efficient "leap" technical innovation in the current loading field. It is suitable for bag piece loading machines placed on the ground or any position above the ground. The technical key is: set the height h of the output end (the upper edge of the rod cylinder) of the transmission belt 2 above the bottom of the totem code basket totem plate 1617 to a constant value (the set height of the original grain bag piece is 10 cm), then: the linear speed V of the transmission belt 2 is intelligently adjusted according to the actual value of the distance d (10 cm ≤ d ≤ 30 cm) between the "output end" and the outer edge of the totem plate of the totem code basket, V = d * r (r is an internal set parameter, see Figure 3The technical principle is that the trajectory of the same object thrown with the same state and speed is invariable.

[0029] II. Rack system

The driving motor 39 drives the driving gear shaft body 41 to complete the X direction send package task by the chain wheel mechanism 40 according to the gear track 35, and the balance wheel shaft body 42 balances the four wheels of the X direction assembly on the track by the force of the buffer spring shaft 43.

[0038] The package basket 4 includes basket frame 18, package front supporting plate 16, package rear supporting plate 17, front and rear supporting plate control cylinder 45, front and rear supporting plate balance tension spring 46, front and rear supporting plate plug-in shaft 47, package discovery switch 19 (basket discovery) see Figure 8The front and rear supporting plates 16 and 17 are rotatably installed on the two sides of the basket frame 18 through the rotatable shaft 47, and the common supporting position (the middle line of the frame) of the two groups of assemblies A and B is referred to as the rear position, and the conveying directions of the assemblies A and B are referred to as the front directions. The control cylinder (or the oil cylinder) installed on the basket frame 18 controls the opening and closing of the supporting plates through the supporting plate handle, and the stroke of the cylinder (or the oil cylinder) is determined by the required opening angle 48 of the supporting plates. The lower end of the balance spring 46 is buckled to the bottom of the basket frame 18, and the upper end is buckled to the supporting plate handle shaft. The balance spring 46 can not only enhance the supporting force of the control cylinder (or the oil cylinder), but also balance the weight of the supporting plates, so that the supporting plates are reset to the closed state when not working. The function of the package detection switch (basket detection) 19 is to feed back the package supporting information in the package supporting basket 4 to the intelligent controller.

[0039] The package supporting basket 4 includes the skills of adjusting the opening angle of the front supporting plate 16 to be greater than or equal to 100 degrees and the opening angle of the rear supporting plate 17 to be less than or equal to 70 degrees, and the opening speed of the front supporting plate 16, so as to realize the skills of the package being placed horizontally and closely to the carriage, as shown in Figure 9 (utility packages are placed on the conveying belt in a horizontal or lateral manner, and the packages are slightly thick or thin).
