Background

The prefilled syringe has the advantages of quick and convenient injection and no need of manual collection of injection by medical staff, so that the prefilled syringe is popular with medical institutions, and the market demand is gradually increased. An important link exists in the process of producing the prefilled syringe: the process comprises the steps of cleaning and drying the pre-filled and sealed injection tubes, wherein the process involves the dispersion treatment of a large number of injection tubes, so that the injection tubes can be orderly arranged and transported on a specific cleaning-drying treatment line.

In order to protect the injection tubes better, reduce the transportation cost and improve the transportation capacity, the injection tube manufacturers usually put a large number of injection tubes into trays in a centralized way, and then stack a plurality of groups of trays carrying the injection tubes for centralized transportation. This causes inconvenience in the subsequent cleaning and drying of the injection tube, and requires a worker to separate a plurality of stacked trays one by one and put them into the cleaning and drying line, in which case the worker needs to continuously separate and take the trays at a high frequency, otherwise the line is short of materials, so that the worker has a high labor intensity and needs to keep on at the inlet end of the line for a long time.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. As used herein, the term "or/and" includes any and all combinations of one or more of the associated listed items.

The utility model provides a tray unstacking and stacking device 100 which is used for a production line for processing medical consumables, and the purpose of the device is to unstack trays 200 loaded with the medical consumables to be processed, namely to separate the trays one by one, then to convey the trays 200 to one end of the upstream of a preset material moving line body, and also to stack the trays 200 loaded with the medical consumables one by one, namely to stack the trays one by one, and then to convey a tray stacking group away from the production line. The present invention is not limited to the type of medical consumables and the process executed by the processing line, and the following embodiments take the pre-filled injection tube production line as an example to describe the structure and operation principle of the tray unstacking device 100.

The tray unstacking and stacking device 100 comprises a conveying mechanism 10, a transfer mechanism 20 and a transfer mechanism 30, wherein the conveying mechanism 10 is used for conveying tray stacks to the transfer mechanism 20 or receiving the tray stacks from the transfer mechanism 20; the transfer mechanism 20 is used as a transfer station for transferring the tray 200 from the conveying mechanism 10 to the tray transfer mechanism 40 in the medical consumable material processing line body, and also can be used as a transfer station for transferring the tray 200 from the tray transfer mechanism 40 to the conveying mechanism 10; the tray transfer mechanism 40 is used for transferring the material loading tray 200 to a subsequent processing station, for example, transferring the tray 200 to a material taking station to separate the tray 200 from the medical consumables, and also can transfer the tray 200 loaded with the medical consumables to the transfer mechanism 20; the transfer mechanism 30 is used as a device for performing unstacking and stacking, and is used for acquiring the trays 200 from the transfer mechanism 20 one by one and conveying the trays to the tray sorting mechanism 40, or acquiring the trays 200 from the tray sorting mechanism 40 one by one and conveying the trays to the transfer mechanism 20, and then unloading the trays 200 to the transfer mechanism 20.

Alternatively, the tray separating and transporting mechanism 40 can be separated from the medical consumable material processing line and arranged in the tray unstacking device 100. The transfer mechanism 30 reciprocates between the transfer mechanism 20 and the tray transfer mechanism 40, so that the unstacking separation of the tray stack can be performed, or the individual trays 200 are continuously stacked to form the tray stack.

Referring to fig. 1 to 2, the conveying mechanism 10 extends toward the transfer mechanism 20 and includes a first transfer unit 11 and a second transfer unit 12 that are disposed side by side, the first transfer unit 11 and the second transfer unit 12 are separated from each other and form an interval area 13 having a certain width and depth and extending toward the transfer mechanism 20, and the tray stack group is driven by the first transfer unit 11 and the second transfer unit 12 together in the interval area 13 and moves toward or away from the transfer mechanism 20. The first transfer unit 11 has a first closed-loop track of its own, and includes a plurality of tray carriers 151 moving along the first closed-loop track, the second transfer unit 12 also has a second closed-loop track of its own, and also includes a plurality of tray carriers 151 moving along the second closed-loop track, the portions of the two closed-loop tracks close to each other form two transfer tracks that are parallel and extend toward the transfer mechanism 20, respectively, and the spacing region 13 is located between the two transfer tracks.

After the tray carrier 151 on the first transfer unit 11 and the tray carrier 151 on the second transfer unit 12 move to the two transfer tracks, they can move close to or away from the transfer mechanism 20 together at the same speed and in the same moving direction. At this time, the tray carriers 151 located on the transfer trajectory of the first transfer unit 11 and the tray carriers 151 located on the transfer trajectory of the second transfer unit 12 correspond to each other one by one, and the two corresponding tray carriers 151 are kept relatively stationary while performing linear motion along the respective transfer trajectories, and together form one tray magazine 15, as shown in fig. 5. Each tray magazine 15 defines an object placing space 16 in the partition area 13, the tray magazine 15 can accommodate a set of tray stacks in the object placing space 16, a plurality of tray brackets 151 in the tray magazine 15 are stacked in the vertical direction, and the parts of the first transfer unit 11 and the second transfer unit 12 corresponding to the respective transfer tracks form a first transfer section and a second transfer section respectively.

When the tray stack is placed in the tray magazine 15 and stably supported by the tray magazine 15, the plane of the bottom surface of the tray 200 at the bottom of the tray stack can be defined as the tray suspension surface 17. The tray suspension surface 17 is always present no matter the tray bin 15 provides support force for the tray suspension surface 17 or provides support force for the side surface of the bottommost tray 200 of the tray stack. The object placing space 16 can be regarded as a space area formed by the tray suspension surface 17 expanding or sweeping along the stacking direction of the tray 200. In this embodiment, the magazine 15 preferably supports the bottom of the stack as shown in FIG. 5.

Alternatively, the two transfer tracks extend in the horizontal direction, and the tray stack can be kept at a fixed horizontal height while moving relatively close to or relatively far from the transfer mechanism 20.

Optionally, the two closed-loop trajectories are located in the same plane or in two planes parallel to each other. When the tray stack reaches the end of the transfer path (either near the end of the transfer mechanism 20 or far from the end of the transfer mechanism 20), which indicates that the part of the tray 200 is to be transferred out of the conveying mechanism 10, the two tray carriers 151 for loading the part of the tray 200 are far away from each other, move along the retracing paths in the respective closed paths, and then reach the sides of the first transfer section and the second transfer section which are far away from each other. Then, the first transfer unit 11 and the second transfer unit 12 continue to operate, and the two tray carriers 151 may reach their respective transfer tracks again. This realizes the loop-back movement and the multiple recycling of the tray holder 151. The first transfer unit 11 and the second transfer unit form a first return section and a second return section, respectively, corresponding to portions of the respective return trajectories.

Alternatively, the retracing trajectory of the first transfer unit 11 is in the shape of a circular arc or a circle-like arc, the center of curvature of which extends vertically, and the retracing trajectory of the second transfer unit 12 is also in the shape of a circular arc or a circle-like arc, the center of curvature of which also extends vertically. The two curvature centers can be the axes of two driving shafts or transmission shafts, and the two driving shafts or the transmission shafts are respectively and vertically arranged on the inner peripheries of the first folding section and the second folding section. The first transfer unit 11 and the second transfer unit 12 may be a transmission assembly in a chain transmission or belt transmission form, and the tray holder 151 may be mounted on a chain or a transmission belt.

Referring to fig. 4 to 5 and again to fig. 1 to 3, in the tray magazine 15 shown in fig. 5, two tray carriers 151 disposed opposite to each other are respectively located on the transfer tracks of the closed-loop tracks to which they belong. Taking the tray carriers 151 located right on the two transfer trajectories and facing each other as a description target, the two tray carriers 151 are separated from each other to form a gap which forms a lifting space 14 opened toward the ground, and the lifting space 14 has the same longitudinal depth as the curvature center direction of the above-mentioned returning trajectory/the direction in which the trays 200 are stacked in the tray magazine 15. Each tray bracket 151 includes a suspension part 1511 for horizontally supporting the bottom of the tray stack, and further includes a limiting part 1512 extending along the longitudinal depth direction/stacking direction of the trays 200 for contacting the side of the tray stack, wherein the limiting part 1512 prevents the trays 200 from inclining, shaking and scattering laterally by stopping the trays.

In this embodiment, the lifting space 14 may be regarded as a part of the storage space 16, or the lifting space 14 and the storage space 16 may be regarded as being connected, and the area where the lifting space 14 and the storage space 16 meet is the lifting space 14 itself. When the tray stack is placed in the tray bin 15, the surface of the bottom of the tray stack, which is not in contact with the suspension portion 1511, expands/sweeps along the stacking direction of the trays 200 to form the lifting space 14. The area of the bottom of the tray 200 not supported by the suspension part 1511 is exposed through the lifting space 14.

Of course, in other embodiments, the overhang 1511 may not necessarily extend horizontally, for example, it may be disposed obliquely to the horizontal and vertical directions to accommodate a tray 200 with a bottom bevel; alternatively, the suspending portion 1511 may directly contact the side portion of the tray 200, and may support the tray 200 by applying a static friction force to the tray 200. In addition, in other embodiments, the tray bracket 151 does not need to be configured as an L-shaped structure, and the suspending portion 1511 does not need to support both ends of the bottom of the tray stack, and can also support the middle position of the bottom of the tray stack.

In addition, the lifting space 14 may also be a side opening provided at the side of the tray bin 15, for example, at the limiting part 1512, the side opening extends along the stacking direction of the trays 200, which allows the side of the tray stack to be exposed, and the tray suspension surface 17 is not lower than the side opening; the size of the side opening in the stacking direction of the tray 200 is not less than the displacement stroke amount of the tray 200 from the supporting of the suspending part 1511 to the complete leaving of the tray bin 15, and at this time, the holding spaces 16 of the holding space 14 are mutually communicated.

It should be noted that the fact that the tray stack group is exposed through the lifting space 14 does not mean that the exposed part can be seen by people, but the exposed part does not contact the tray bin 15, or the exposed part is not covered by the tray bin 15.

The transfer mechanism 20 includes a suspension unit and a lifting unit, the suspension unit can enter the lifting space 14 between two oppositely disposed tray brackets 151 and contact the region where the bottom of the tray stack is exposed through the lifting space 14 (for convenience of description, hereinafter referred to as the bottom exposed region). The two tray holders 151 disposed opposite to each other are two tray holders 151 belonging to the first transfer unit 11 and the second transfer unit 12, respectively, located in two transfer tracks, and corresponding to each other to form one tray magazine 15. The lifting space 14 can be regarded as a space formed by the bottom exposed area of the tray stack moving along the extending direction of the limiting part 1512. After the suspension unit contacts the bottom exposed area of the tray stack, the tray bracket 151 no longer provides support for the tray stack. The lifting unit comprises a power source for driving the suspension unit to move up and down in the lifting space 14 relative to the conveying mechanism 10, the power direction output to the suspension unit is the longitudinal depth direction of the lifting space 14/the stacking direction of the trays 200, and the distance between the suspension unit and the suspension part 1511 can be changed.

In this way, the vertical height of the bottom of the stack of trays lifted by the suspension unit changes, which is coordinated with the stack thickness of the stack of trays, i.e. the distance between the top and the bottom of the stack of trays. No matter the process of unstacking or stacking, the top of the tray stack group is always kept at a certain fixed height position, so that the transfer mechanism 30 can conveniently acquire the top tray 200 of the tray stack group, or unload the tray 200 at the height position. When the transfer mechanism 30 obtains or unloads one tray 200, the lifting unit drives the suspension unit to move through the thickness stroke of one tray 200, so that the next top tray 200 fills the position of the previous top tray 200. The height position is a limit position in the reciprocating motion of the transfer mechanism 30, and the transfer mechanism 30 does not need to meet the change of the stacking thickness of the tray stack group, and can obtain the tray 200 only by reaching the limit position for multiple times and repeatedly turning back.

Referring to fig. 2 to 5, the suspension unit includes a first suspension assembly 211 and a second suspension assembly 212 that are independent from each other, and the lifting unit includes a first lifting assembly 221 and a second lifting assembly 222 that are respectively connected to the first suspension assembly 211 and the second suspension assembly 212 in a driving manner. The first lifting assembly 221 can drive the first suspension assembly 211 to reciprocate within a first lifting stroke, and the second lifting assembly 222 can drive the second suspension assembly 212 to reciprocate within a second lifting stroke. The directions of the first lifting stroke and the second lifting stroke are both consistent with the longitudinal depth direction of the lifting space 14, and the first lifting stroke and the second lifting stroke are jointed in the direction and do not form an overlapping or overlapping part. The two limit positions of the first lifting stroke are respectively a material receiving position at one side of the tray suspension surface 17 facing the ground and a connection position at one side of the tray suspension surface 17 far away from the ground; the two limit positions of the second lifting stroke are the handover position and the material taking position on the side, far away from the ground, of the material plate suspension surface 17. Wherein the distance from the material taking position to the suspension part 1511 is greater than the distance from the delivery position to the suspension part 1511.

Further, the transfer mechanism 20 further includes a telescopic unit 23, and the telescopic unit 23 is configured to drive the second suspension assembly 212 to enter or exit the lifting space 14; alternatively, the telescoping unit 23 is used to drive the second suspension assembly 212 into and out of the storage space 16. The output of power from the telescoping unit 23 to the second suspension assembly 212 is a result of the action and positioning of the first suspension assembly 211. Only when the first suspension assembly 211 first reaches the handover position, the telescopic unit 23 can drive the second suspension assembly 212 to enter or exit the lifting/storage space 14/16.

It is worth to be noted that, when the tray stack group is lifted and supported by the tray bin 15, the first lifting assembly 221 can only drive the first suspension assembly 211 to move in the lifting space 14, and the first suspension assembly 211 can only contact the exposed part of the tray stack group through the lifting space 14; when the first suspension assembly 211 drives the tray stack group to separate from the suspension portion 1511, the exposed area of the tray stack group is larger, so that when the tray stack group is handed over from the first suspension assembly 211 to the second suspension assembly 212, the telescopic unit 23 can drive the second suspension assembly 212 to enter the lifting space 14, and can also drive the second suspension assembly to enter other areas of the storage space 16 except the lifting space 14 to support the tray stack group.

Alternatively, in this embodiment, the telescopic unit 23 is connected to the power output end of the second lifting assembly 222 and directly drives and connects the second suspension assembly 212, in addition, the opening of the spacing region 13 between the first transfer unit 11 and the second transfer unit 12 directly faces the second lifting assembly 222, the second suspension assembly 212 and the telescopic unit 23, and the telescopic unit 23 drives the second suspension assembly 212 to move in the spacing region 13 to enter or exit the object placing space 16 or the lifting space 14.

It is understood that in other embodiments, the extension unit 23 may also be in driving connection with the second lifting assembly 222, and the second lifting assembly 222 is directly in driving connection with the second suspension assembly 212; or, the number of the telescopic units 23, the second lifting assembly 222, and the second suspension assembly 212 may also be two, and the two sets of telescopic units 23 respectively drive the two sets of second suspension units to move in opposite directions from two opposite sides of the tray bin 15 to enter the lifting space 14 or the storage space 16, or move in opposite directions to exit, at this time, through holes or through grooves may be respectively formed in the two opposite tray brackets 151 to allow the two second suspension units to penetrate into the through holes.

The operation of the suspension unit and the lifting unit will be described by taking the unstacking process of the trays 200 as an example. Firstly, the conveying mechanism 10 drives the tray bin 15 carrying the tray stack group to move relatively close to the transfer mechanism 20, when the part of the trays 200 reach the joint of the first transfer section and the first turning section/the joint of the second transfer section and the second turning section, the conveying mechanism 10 stops running, and before the running is stopped, the first suspension support assembly 211 stays at the material receiving position in advance to wait for the tray stack group to be in place. Then, the first lifting assembly 221 drives the first suspension assembly 211 to contact and lift the exposed bottom area of the tray stack group, so as to apply a lifting force to the first suspension assembly 211, and drive the tray stack group to move up until the first suspension assembly 211 reaches the position of the connection position, where the first lifting assembly 221 stops driving. During this lifting movement, the first lifting assembly 221 is able to output a linear driving force to the first suspension assembly 211 to move it continuously without interruption, while the second suspension assembly 212 has previously stayed at the vertical level at the interface position waiting for the tray stack.

Then, in response to the first suspension assembly 211 being in the transfer position and driving the second suspension assembly 212 into the lifting space 14 to reach the transfer position, the telescoping unit 23 transfers the tray stack from the first suspension assembly 211 to the second suspension assembly 212, and the tray 200 at the top of the tray stack is in the material taking position. Then, the first lifting assembly 221 reversely drives the first suspension assembly 211 to descend and return to the material receiving position again, and the second lifting assembly 222 outputs intermittent ascending driving force to the second suspension assembly 212, and each time the second suspension assembly 212 is driven, the second suspension assembly 212 moves upwards through a material tray thickness stroke. Each time the second lifting assembly 222 is driven to lift, one top tray 200 is taken by the transfer mechanism 30. Finally, the last tray 200 on the second tray suspension assembly 212 reaches the pick-up position and is removed by the transfer mechanism 30, indicating the end of the unstacking process, at which time a new group of tray stacks has been suspended by the first tray suspension assembly 211 at the transfer position. After the unstacking is completed, the second lifting assembly 222 reversely drives the second suspension assembly 212 to descend and return to the transfer position again, and receives and drives a new tray stack group to ascend.

Optionally, the sum of the first lifting stroke and the second lifting stroke is greater than or equal to the longitudinal depth dimension of the tray bin 15, or greater than the extension length of the limiting part 1512 of the tray bracket 151 in the longitudinal depth direction.

Optionally, in this embodiment, each of the first lifting assembly 221 and the second lifting assembly 222 uses a linear cylinder as a lifting driving source, and the sum of the telescopic driving strokes of the two linear cylinders is the sum of the first lifting stroke and the second lifting stroke. Compared with the scheme that only one linear cylinder is selected as a lifting driving source to drive one suspension assembly, the specification of the two selected linear cylinders is reduced, the maximum extension length of the push rod of each linear cylinder is correspondingly reduced, the coaxiality deviation of the push rod and the cylinder body is reduced, the operation stability of each linear cylinder can be improved, and the service life and the maximum use times are prolonged.

Alternatively, the transfer mechanism 30 includes a transfer unit 31 that reciprocates between the tray transfer mechanism 40 and the relay mechanism 20, and a material-taking and discharging unit 32 rotatably mounted on the transfer unit 31, and the material-taking and discharging unit 32 can rotate relative to the transfer unit 31 according to the change of the orientation angle of the tray 200, and finally the separated tray 200 is placed on the tray transfer mechanism 40 in the same orientation, or the tray 200 obtained from the tray transfer mechanism 40 is unloaded on the relay mechanism 20 in the same orientation and stacking is completed.
