Therefore, in order to solve the above problems, it is necessary to provide a feeding device capable of ensuring that a sample is discharged in a preset posture.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that guarantee that the sample can be with the ejection of compact of predetermineeing the gesture in the material loading machine, aim at provides a scraping wings and sample loading attachment.

The utility model discloses a following technical scheme realizes:

the utility model provides a scraping wings for push away material to the sample among the loading attachment, be equipped with on one side of scraping wings along the long axis interval arrangement in this side and be used for supporting the supporter of sample, the interval of two adjacent supporters is greater than the maximum diameter of sample just is less than the length of sample, still is provided with the guide surface that does benefit to sample and scraping wings separation between two adjacent supporters, and when the scraping wings lifted the sample, the guide surface formed the contained angle with the horizontal plane.

The sample is supported by the support body, and after the power source is configured for the material pushing plate, the power source drives the material pushing plate to move so as to drive the sample to be loaded. In the feeding process, due to the arrangement of the mutual intervals of the supporting bodies, the posture of the sample on the supporting bodies can be uniquely determined as the lying posture, and the posture is the preset optimal posture for the sample to enter the transmission line. The sample in the non-preset posture, namely the sample vertical to the material pushing plate is separated from the material pushing plate due to the gap between the supporting bodies, the sample is directionally separated through the guide of the guide surface in the separation process, and meanwhile, the sample can be prevented from being retained between the supporting bodies due to the arrangement of the guide surface.

In this scheme, do benefit to sample and scraping wings separation and indicate: when one end of the sample is between the two supports, the end will contact the guide surface, if the guide surface is horizontal, the sample can be independently arranged on the guide surface, the sample is not separated from the material pushing plate at the moment, when the guide surface forms an included angle with the horizontal plane, the included angle can be divided into a first state included angle and a second state included angle, when the included angle is the first state included angle, one end of the sample is vertically attached to the guide surface, the other end of the sample is contacted with the fixed plate, and the sample and the material pushing plate are not separated, when the included angle is in the second state, one end of the sample is vertically attached to the guide surface, the other end of the sample is suspended without contact, the sample is used for downward movement under the action of gravity, the sample and the material pushing plate are in a separated state, namely, under the working state, when the guide surface and the horizontal plane form a second state included angle, the guide surface at the moment is the guide surface which is beneficial to the separation of the sample and the material pushing plate.

When the angle between the guide surface and the horizontal plane is too small, the samples may be in a balanced state so that the samples cannot slide off the guide surface because different samples have different weights, that is, different samples in the same posture have different gravity center positions.

Preferably, the width of the support body in the arrangement direction is less than 0.15-0.3R, wherein R is the maximum diameter of the sample. The single support body can also be an independent support for keeping the sample in the vertical state, so the width of the support body in the arrangement direction of the support body should be limited to a certain extent, and in the scheme, the inventor finds out that when the width is smaller than 0.3R, the sample cannot stand on the single support body independently in the feeding process. Of course, the upper limit of this width is based on the fact that the specimen will also be subjected to vibrations of the apparatus during loading.

Preferably, the distance between two adjacent supports is less than or equal to 1/3L, wherein L is the length of the sample. When the number of the supports is only two, the distance between the supports can be larger than the diameter of the sample and smaller than the length of the sample. However, when the supports are arranged in more than two, the spacing between adjacent supports is too large, which easily results in that the sample cannot be effectively supported by the supports, i.e. the sample may only contact with one support, for example, when the spacing between two adjacent supports is larger than 1/2L, and thus the feeding efficiency of the sample cannot be guaranteed. Set up the interval of adjacent supporter to be when being less than or equal to 1/3L can guarantee that the sample can contact with two supporter at least under the horizontal gesture to make the sample can be by the steady support, thereby guarantee the material loading efficiency of sample.

A sample feeding device comprises the material pushing plate, the material pushing plate is connected with a power source in the feeding device to enable the material pushing plate to do reciprocating linear motion, and the material pushing plate lifts a sample to achieve feeding.

In this scheme, adopt foretell scraping wings to carry out the material loading to the sample, can guarantee that the sample is the decurrent gesture on the scraping wings, predetermine the gesture promptly, the sample loading attachment that this scheme provided promptly can guarantee the sample and with the ejection of compact of predetermined gesture, has avoidd the change design of transmission line, has avoidd the design of recovery channel simultaneously, reduces the structural complexity of device, has avoided the repacking of transmission line, has reduced the manufacturing cost of device, has guaranteed the transmission stability of transmission line.

Preferably, the number of the material pushing plates is at least two, and the supporting bodies of two adjacent material pushing plates are arranged in a staggered mode along the long axis direction. The arrangement of the two material pushing plates realizes that: when the sample is lifted to the support body with high height even though the sample realizes vertical posture on the support body with low height, the sample can be separated from the material pushing plate through the guide surface of the material pushing plate with high height due to the staggered arrangement of the support bodies of the two material pushing plates.

Preferably, the two sides of the support body on the pushing plate with the lowest height are provided with sensors for detecting the samples. The sensor is used as a corresponding mark for starting and ending feeding, so that the timeliness of feeding is guaranteed, the empty feeding condition is prevented, and the energy is saved.

Preferably, the device comprises a scanning device, wherein the scanning device is connected with the material pushing plate, and the scanning device is used for scanning the bar codes of the samples on the rod material pushing plate. The sample can contact with the fixed plate in the process of being promoted, because the mutual friction between sample and the fixed plate can impel the sample rotatory to make the bar code on the sample self can just to accomplish the input of sample bar code information to scanning direction of scanning device.

Detailed Description

To make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the following examples and drawings, and the exemplary embodiments and descriptions thereof of the present invention are only used for explaining the present invention, and are not intended as limitations of the present invention.

Examples

As shown in fig. 1, a material pushing plate is used for pushing a sample 7 in a feeding device, a side surface of the material pushing plate 1 is provided with supporting bodies 2 which are arranged at intervals along a long axis in the side surface and are used for supporting the sample 7, the distance between two adjacent supporting bodies 2 is greater than the maximum diameter of the sample 7 and is smaller than the length of the sample 7, a guide surface 3 which is beneficial to separation of the sample 7 from the material pushing plate 1 is further arranged between two adjacent supporting bodies 2, and when the material pushing plate 1 lifts the sample 7, an included angle is formed between the guide surface 3 and a horizontal plane.

In the present embodiment, the material pushing plate 1 is a square plate, wherein one side surface of the square plate extends outwards to form a plurality of supporting bodies 2, the cross-sectional shape of the supporting bodies 2 is trapezoidal, and the guiding surface 3 can be formed by chamfering the side surface of the square plate. It should be noted that the inclined direction of the guide surface 3 with respect to the support body 2 is not limited as long as it is formed by chamfering the side surface as described above, and the guide surface 3 mainly plays a role in attachment of the ejector plate 1, and for example, in the loading device, the ejector plate 1 needs to be attached to the fixed plate 4 in a manner such that the guide surface 3 faces away from the fixed plate 4. The cross-sectional shape of the support body 2 in the embodiment is only an implementation means that the inventor has used for routine practice, for example, in some embodiments, the overall shape of the support body 2 may be a cylinder, a regular polygon prism, a cone, etc., which mainly functions to support the sample 7, as long as the support body has a support point, a support surface, a support line, etc. for supporting the sample 7, and the specific shape may not be limited.

The working principle is as follows: the sample 7 is supported by the supporting body 2 of the material pushing plate 1, the material pushing plate 1 is configured with a power source and then makes reciprocating linear motion along the direction vertical to the supporting surface, and at the moment, the sample 7 is lifted under the driving of the material pushing plate 1. The sample 7 has two states when it reaches the stripper plate 1: one is that the sample 7 is horizontally laid on a plurality of supporting bodies 2, namely, a tube body of the sample 7 is contacted with the plurality of supporting bodies 2, the posture of the sample 7 is a preset discharging posture, and the sample 7 smoothly enters a transmission line without extra posture adjustment under the condition of keeping the discharging posture; one is upright on the supporting body 2, the posture is a non-preset discharging posture, samples 7 are discharged in the posture, after the samples reach the transmission line, the posture needs to be corrected or the samples 7 are recovered to a discharging device for discharging again, due to the arrangement of the supporting body 2, the spaced supporting bodies 2 screen the samples 7 in different postures, and after the material pushing plate 1 is driven, the upright samples 7 are separated from the material pushing plate 1 through the guide surfaces 3 between the adjacent supporting bodies 2, so that the samples 7 are prevented from being discharged in the upright posture. It should be noted that, in the present embodiment, the width of the material pushing plate 1 is not limited, which depends on the specific loading environment: for example, when the discharging requirement is one sample 7 at a time, the width of the material pushing plate 1 should be less than twice the length of the sample 7, and when the discharging requirement is a plurality of samples 7, the width of the material pushing plate 1 is more than several times the length of the sample 7, it is sufficient to note that a plurality of materials should be understood as a case of allowing a plurality of materials to be discharged at a time in the discharging environment, rather than a case of fixing a plurality of materials to be discharged at a time.

In a possible embodiment, as shown in fig. 3, the support body 2 has a concave surface for supporting the sample 7, which is adapted to the tubular body of the sample 7. The concave surface sets up the area of contact that reduces upright state's sample 7 and supporter 2 on the one hand for upright state's sample 7 is difficult to more keeps upright state on supporter 2, and on the other hand, when this concave surface sets up to fit for with sample 7 pipe shaft, the area of contact of sample 7 and supporter 2 of recumbent is bigger, and the concave surface still plays certain limiting displacement to sample 7, prevents that the possible shake of device from making recumbent sample 7 and supporter 2 take place to separate, has guaranteed sample 7's ejection of compact efficiency.

In a possible embodiment, the angle formed by the guide surface 3 and the horizontal plane is greater than or equal to 45 ° and less than 90 ° when the stripper plate 1 is in the working state. In this embodiment, when the material pushing plate 1 is in the working state, the material pushing plate 1 is in an inclined state relative to the vertical direction, and at this time, the larger the included angle between the guide surface 3 and the horizontal plane is, the easier the sample 7 is to be separated from the material pushing plate 1 under the guide of the guide surface 3, of course, the included angle should be smaller than 90 degrees, when the included angle is 90 degrees, the vertical plane is displaced, and at this time, the sample 7 is easy to be retained between the two supporting bodies 2 in an upright posture. In practical implementation, 45 ° is preferred to reduce the processing cost.

In a possible embodiment, the width of the support 2 in the direction of its arrangement is less than 0.15R to 0.3R, where R is the maximum diameter of the sample 7. The single support body 2 can also be an independent support for keeping the sample 7 in the vertical state, so the width of the support body 2 in the arrangement direction of the support body 2 should be limited to a certain extent, in the embodiment, the inventor finds out according to experimental demonstration that when the width is smaller than 0.3R, the sample 7 can not stand on the single support body 2 independently in the feeding process, the lower limit value of the width is as small as possible in principle, as long as the width meeting the processing requirement is all, the width of the support body 2 is set to be 0.15R under the general condition, specifically 2.5-5 cm, the support body 2 matched with the width can be selected and set according to the specification of the sample 7 pipe. The upper limit of this width is, of course, based on the fact that the specimen 7 is also subjected to vibrations of the apparatus during loading.

In a possible embodiment, the distance between two adjacent supports 2 is less than or equal to 1/3L, where L is the length of the sample 7. When the number of the supports 2 is two, the distance therebetween is larger than the diameter of the sample 7 and smaller than the length of the sample 7. However, when the supports 2 are arranged in more than two, the spacing between the adjacent supports 2 is too large, which easily results in that the sample 7 cannot be effectively supported by the supports 2, i.e. the sample 7 may only contact with one support 2, for example, when the spacing between the adjacent supports 2 is larger than 1/2L, and thus the feeding efficiency of the sample 7 cannot be guaranteed. When the distance between the adjacent supports 2 is set to 1/3L or less, the sample 7 can be ensured to be at least contacted with the two supports 2 in the horizontal posture, so that the sample 7 can be stably supported, and the feeding efficiency of the sample 7 is ensured. The distance between the two supporting bodies 2 is preferably 16-19 mm in the embodiment, and based on the maximum diameter of the tube of each batch of samples 7, for example, the maximum diameter of the common sample 7 is 16mm, the distance between the supporting bodies 2 can be set to be 18-19 mm, and when the sample 7 stands on a single supporting body 2, the sample can be slightly vibrated during the lifting process and automatically topples over the supporting body 2, namely, the sample can lie on the supporting body 2 without separating from the material pushing plate 1 between the supporting bodies 2.

A sample feeding device is shown in fig. 2, and comprises the material pushing plate 1, wherein the material pushing plate 1 is connected with a power source in the feeding device so as to enable the material pushing plate 1 to make reciprocating linear motion, and the material pushing plate 1 lifts a sample 7 so as to realize feeding.

The working principle is as follows: after the sample 7 is put into the feeding device, the sample 7 is firstly contacted with the material guide plate 8, because the material guide plate 8 is obliquely arranged, the sample 7 slides to the supporting body 2 from the material guide plate 8 according to the self gravity action, at the moment, the material pushing plate 1 drives the sample 7 to move under the driving of the power source, namely, the sample 7 is lifted, in the moving process of the material pushing plate 1, the horizontal sample 7 is smoothly lifted to a preset destination, the vertical sample 7 is separated from the material pushing plate 1 through the screening of the material pushing plate 1, and the sample 7 returns to the material guide plate 8 again to wait for the next screening and lifting.

In this embodiment, adopt foretell scraping wings 1 to carry out the material loading to sample 7, can guarantee that sample 7 is the recumbent gesture on scraping wings 1, predetermine the gesture promptly, the sample 7 loading attachment that this scheme provided promptly can guarantee sample 7 and with the ejection of compact of predetermined gesture, has avoidd the change design of transmission line, has avoidd the design of recovery channel simultaneously, reduces the structural complexity of device, has avoided the repacking of transmission line, has reduced the manufacturing cost of device, has guaranteed the transmission stability of transmission line.

When the number of the material pushing plates 1 is two or more, the relative position of the material pushing plates 1 can be set according to the relative position of the pushing plates in the pushing plate type feeding device in the prior art. When the sample 7 is in the vertical posture on the material pushing plate 1 with the lower height and is always kept in the vertical posture in the lifting process, the sample 7 is lifted to the material pushing plate 1 with the higher height, because the material pushing plate 1 and the support bodies 2 of the material pushing plate 1 with the lower height are arranged in a staggered manner, the sample 7 is just between the two support bodies 2, and when the material pushing plate 1 with the higher height moves, the sample 7 slides downwards from the guide surface 3 of the material pushing plate 1 with the higher height and returns to the material guide plate 8 again. The staggered arrangement of the supports 2 of the two ejector blades 1 makes it possible for the specimen 7, even if it is in an upright position on the ejector blade 1 with a lower height, to be returned to the guide plate 8 again by the guide surface 3 of the ejector blade 1 with a higher height when the specimen 7 is lifted onto the ejector blade 1 with a higher height. Certainly, the setting of two scraping wings 1 can be adjacent, also can be the spaced, when the interval, can set up the push pedal among a plurality of prior art between two scraping wings 1, nevertheless consider the utility model discloses sample 7 to be medical field, preferably set up to two scraping wings 1 adjacent to make the stroke that sample 7 slided and falls shorter, reduce the collision strength between sample 7 and the stock guide 8.
