In a production line, in the process of boxing products and accessories thereof, the accessories are often neglected or mistakenly installed.

In the existing mode, the problem is solved by a manual reinspection mode. A manual review is performed to see if a predetermined number of accessories are loaded, each time a particular set of accessories is loaded, based on a predetermined number of accessories. In this manner, the likelihood of a low or wrong removal of the accessory is relatively high, due to the inability to monitor each removal of the accessory. In addition, frequent rechecks cause the boxing work to be stopped frequently, reducing the production efficiency.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an auxiliary device for accessory is taken on production line, it can monitor the accessory operation of taking each time, places to take or take the accessory by mistake less, avoids frequent reinspection, improves production efficiency.

In order to achieve the above object, the utility model provides an auxiliary device that is used for accessory to take on production line, auxiliary device includes one and puts the thing subassembly, include: the storage system comprises at least two storage units, a control unit and a control unit, wherein each storage unit comprises an isolation bracket for isolating a storage space in which accessories can be placed and a photoelectric sensor arranged on the isolation bracket; the cross beam comprises at least two indicating lamps, and each indicating lamp corresponds to one storage unit; and the controller is electrically connected to the photoelectric sensor and the indicator light, so that the indicator light corresponding to the object placing unit where the photoelectric sensor is positioned switches the indicating state when the photoelectric sensor is triggered.

In the above mode, auxiliary device can replace the artifical reinspection of product and accessory on the production line, monitors the accessory operation of taking at every turn, prevents that the accessory from taking or taking by mistake less, improves production efficiency.

In another exemplary embodiment of the auxiliary device, the cross beam includes at least two sensor sockets, each sensor socket is electrically connected to the controller and corresponds to one of the object placing units, and each photoelectric sensor is electrically connected to the controller in a pluggable manner through the sensor socket corresponding to the object placing unit where the photoelectric sensor is located.

In the above manner, for a certain number of storage units, when the number of accessories to be packed is less than the number of storage units, only the required number of photoelectric sensors may be plugged into the corresponding sensor sockets, so as to be electrically connected to the controller for use.

In another exemplary embodiment of the auxiliary device, the photosensor comprises a trigger interval control unit, which can disable the photosensor for a predetermined time interval after being triggered.

A photoelectric sensor is generally used, which emits a light beam by an emitting device and receives it by a receiving device. Ideally, the manual removal of the fitting is such that the light beam is blocked only once per removal operation, thereby triggering the photosensor only once. However, in practice, the limb may occlude the light beam twice or even more each time the accessory is manually removed. This situation can result in the accessory being removed once but the photosensor being triggered twice or even more, thereby interfering with the proper operation of the accessory. Considering that the operating time for each taking of the accessory is short, that is, the triggering interval for triggering the photoelectric sensor twice or even more times is short, in such a manner that the light beam emitted by the photoelectric sensor is blocked for a plurality of times within a predetermined time interval and only the first blocking triggers the photoelectric sensor, it is possible to prevent the blocking of the light beam twice or even more times for one operation from affecting the normal operation of the auxiliary device.

In another exemplary embodiment of the auxiliary device, the photosensor is a light curtain sensor.

In the above manner, the light curtain sensor has a plurality of emission tubes emitting light beams, thereby forming the light curtain. The existence of light curtain can prevent effectively once in the operation of taking the accessory that the condition that limbs sheltered from many times takes place, guarantees auxiliary device's normal work.

In another exemplary embodiment of the auxiliary device, the crossbar further comprises at least two switches, each switch corresponding to one of the storage units, each switch being electrically connected to the controller and configured to enable or disable the storage unit corresponding thereto.

In the above manner, when the auxiliary device is idle, all the switches may be in the off state to disable all the storage units. After the storage unit is put into use, the switches corresponding to the storage units with the same number can be switched to the on state according to the number of the required box accessories, so that the corresponding storage units are started. The object placing unit with the switch in the off state is in the forbidden state, and the normal work of the auxiliary device is not influenced.

In another exemplary embodiment of the supplementary device, the supplementary device further comprises a counter electrically connected to the controller, the counter including a display screen, the counter being configured to increment the counted number of times each of the photosensors is activated once and to display the incremented number of times on the display screen.

In this manner, the auxiliary device can count the number of fittings packed in total. Since the number of fittings used is generally known in advance, it is possible to further confirm whether a batch of fittings is misloaded or misloaded after comparison with the number of fittings in the package.

In another exemplary embodiment of the auxiliary device, the counter comprises a power-off maintaining unit configured to hold and restore the counter after power restoration for the number of times counted last before the power-off.

In this way, the auxiliary device can be prevented from losing the counted number of boxed accessories due to power failure during the production process.

In another exemplary embodiment of the accessory device, each of the storage units includes a weighing device electrically connected to the controller.

The weight of each identical standard fitting is consistent. In this way, the number of fittings that have actually been packed can be known during production by the difference in weight between the fittings of the storage unit before and after they have been taken. By comparing the number of accessories of each enabled object placing unit, whether the accessories packaged each time are accurate or the accessories are taken by mistake rarely can be detected.

In another exemplary embodiment of the auxiliary device, the auxiliary device comprises at least two of the placement modules, the placement modules comprising a module interface, the photoelectric sensor and the indicator light of the placement module being configured to be electrically connectable to the controller in a pluggable manner via the respective module interface.

In such a way, the auxiliary device has expandability, and when the number of the object placing units included in one object placing component is less than that of a set of accessories to be boxed, the number of the object placing units of the auxiliary device can be expanded by inserting the second object placing component, so that the production requirement is met.

The definition of a term is consistent throughout the specification unless the context clearly dictates otherwise.

Fig. 1 schematically shows an auxiliary device according to the invention. As shown in fig. 1, the auxiliary device includes a placement assembly 10 and a controller (not shown). The storage assembly 10 includes at least two storage units 11 and a beam 12.

One storage assembly 10 of the auxiliary device may include at least two storage units 11, which means that one storage assembly 10 may include two storage units 11, or may include more than two storage units 11. In practice, the shelving assembly 10 includes several shelving units 11, depending on the number of sets of accessories required for the packaging of most products on the production line. For example, as shown in fig. 1, if a storage assembly 10 includes 4 storage units 11, which can meet the requirements of most products on the production line, such as more than 90% or even more than 95%, it is a relatively cost-effective way to configure 4 storage units 11 for one storage assembly 10. As for a few products, the number of the fittings is more than 4, and the production requirement can be met by electrically connecting two storage assemblies 10 by using one controller.

As shown in fig. 1, the storage unit 11 includes an isolation bracket 111 for isolating a storage space in which accessories can be placed. In the case where a plurality of the storage units 11 are arranged in a side-by-side order, the partition brackets 111 of adjacent storage units 11 may be closely adjacent to each other. If it is considered from the viewpoint of cost reduction, it is also conceivable to use a separate bracket instead of the separate bracket 111 where the two adjacent storage units 11 are close together, and the width of the separate bracket used for replacement may be slightly larger to facilitate the placement of the photoelectric sensor.

As shown in fig. 1, each placement unit 11 further includes a photoelectric sensor 112. The photoelectric sensor 112 is fixed to a side of the isolation bracket 111, and in use, the side on which the photoelectric sensor 112 is mounted faces a pickup person. Thus, when the person taking the accessory gets the accessory, the limb can block the light beam emitted by the photoelectric sensor 112, so that the photoelectric sensor 112 can sense the operation of taking the accessory. In the case where the photoelectric sensor 112 is a correlation type photoelectric sensor, the emitter and the receiver of the photoelectric sensor 112 are fixed to the isolation brackets 111 on both sides of the placement unit 11, respectively; in the case where the photoelectric sensor 112 is a reflective photoelectric sensor, the sensor body and the reflector are fixed to the isolation brackets 111 on both sides of the placement unit 11.

As shown in fig. 1, the storage assembly 10 further includes a cross member 12, and the storage unit 11 is fixedly attached to the cross member 12. The beam 12 may span and be fixed to the spacer bracket 111. The beam 12 includes at least two indicator lights 121, and for the convenience of viewing, as shown in fig. 1, each indicator light 121 corresponds to one object placing unit 11, so that whether or not the accessory in the object placing unit 11 is taken can be determined by indicating the change of the state through the indicator light 121. As shown in fig. 1, the beam 12 may be hollow to facilitate the placement of wires to the controller and devices such as indicator lights 121.

The controller is used for electrically connecting and controlling each electric component of the auxiliary device, and the electrical connection can be connected in various modes such as direct connection through a wire or connection through a pluggable interface. As shown in fig. 1, a control box may be disposed at one side of the storage unit 11, and a controller may be placed therein.

The photoelectric sensor 112 and the indicator light 121 are each electrically connected to the controller. The wires connecting the photosensor 112 and the controller can be routed as follows: first to the beam 12 via the corresponding spacer bracket 111 and then to the controller via the beam 12, e.g. its hollow part.

When the object placing unit 11 is used for taking out the accessory, the corresponding photoelectric sensor 112 is triggered, and after the controller receives a signal sent by the photoelectric sensor 112, the indicator light 121 corresponding to the object placing unit 11 is controlled to switch the indicating state. The indication state can be switched in various ways, for example, a green indicator light can be used, the photoelectric sensor 112 triggers the front indicator light 121 to be turned off, and the rear indicator light 121 to be turned on to indicate that the accessory is taken; or a red indicator light is used, the photoelectric sensor 112 triggers the front indicator light 121 to be turned on, the accessory is not taken, and the rear indicator light 121 is turned off after triggering; or a red-green double-color indicator light is used, the photoelectric sensor 112 triggers the front indicator light 121 to be red to indicate that the accessory is not taken, and triggers the rear indicator light 121 to be green to indicate that the accessory is taken. The photoelectric sensors 112 corresponding to the object placing units 11 requiring taking the accessories are all triggered, the corresponding indicator lamps 121 are all switched to the states, which indicates that the taking operation of one round is completed, and the controller can restore the indicator lamps 121 to the states before the switching so as to prepare for the taking operation of the next round.

In an embodiment of the present invention, the beam 12 includes at least two sensor sockets (not shown), each sensor socket is electrically connected to the controller and corresponds to one of the object placing units 11, and each photoelectric sensor 112 is electrically connected to the controller through the sensor socket corresponding to the object placing unit 11. In the case where the number of kit-of-parts that need to be binned is less than the number of storage units 11 that the storage assembly 10 includes, for example, the storage assembly 10 of fig. 1 includes 4 storage units 11, if there are 3 kit-of-parts, then only the photosensors 112 of three storage units 11 need to be docked to the sensor docking ports, and the other storage unit 11 can be left idle. This may allow for better adaptability of the auxiliary device.

Generally, the transmitter of the photosensor 112 emits a light beam and is received directly (correlation sensor) or indirectly (reflective sensor) by a receiver. The photosensor 112 is triggered once the receiver fails to receive the light beam due to blockage by an object, such as a blockage of a limb during an accessory handling operation. If the object leaves the range of the beam irradiation and is blocked again, the photoelectric sensor 112 is triggered once again. In actual accessory handling operations, limb occlusion, detachment and re-occlusion may occur, which may result in two or more triggers to the photosensor 112 for one handling operation.

To avoid this, optionally, in an embodiment of the present invention, the photosensor 112 includes a trigger interval control unit (not shown) that may cause the photosensor 112 to be not triggered for a predetermined time interval after being triggered. The predetermined time interval can be set according to the time required for taking the accessory once in actual production.

Optionally, in another embodiment of the present invention, the photosensor 112 is a light curtain sensor. The light curtain sensor includes a plurality of emission tubes that emit light beams to form a light curtain. Because the light curtain is not a single light beam, the situation that limbs are shielded, leave and are shielded again can be avoided in the operation of taking the accessory once, so that the situation that the photoelectric sensor 112 is triggered twice or for multiple times due to the operation of taking once is effectively avoided.

Optionally, in another embodiment of the present invention, the beam 12 includes at least two switches 122, each switch 122 corresponds to one storage unit 11, and each switch 122 is electrically connected to the controller and configured to enable or disable the storage unit 11 corresponding thereto. In actual use, by switching the state of the switch 122, the shelving units 11 may be disabled, such that a shelving assembly 10 having a fixed number of shelving units 11 is more adaptable for use in packaging products having different numbers of accessories.

Optionally, in another embodiment of the present invention, the auxiliary device further comprises a counter (not shown) electrically connected to the controller, which comprises a display 13. Each photosensor 112 is activated once and the counted number is incremented once and the incremented number is displayed on the display 13. For example, in fig. 1, the storage assembly 10 includes four storage units 11, in the case of packing a product with 4 accessories, one accessory packing is taken from each storage unit 11, the photoelectric sensor 112 of each storage unit 11 is triggered once, and then one round of accessory taking is completed, the number of times counted by the counter is increased once on the original basis, and the increased number of times is displayed on the display 13. The counting function can be completed by only configuring a simple logic circuit in the counter. For example, the logic circuit includes an AND gate connected to each photosensor 112 and an accumulator connected to the output of the AND gate. The and gate output is set when each photosensor 112 is set to trigger, and the accumulator is incremented. The counter may be placed in the control box as the controller and the display 13 may be mounted on one side of the control box or, for ease of viewing, on the beam 12 as shown in figure 1. The number of times counted by the counter can be used for knowing the number of the products and the accessories of the products which are packed together, and whether the number of the sets of the products and the number of the accessories which are actually packed are consistent can be further checked after a certain number of accessories are packed, so that the accuracy of packing is ensured.

During use of the accessory, the number of times counted by the counter may be lost in the event of a power outage. To address this, optionally, in another embodiment of the present invention, the counter includes a power outage holding unit (not shown) capable of holding and restoring the number of times the counter was last counted before the power outage after the power supply was restored.

Optionally, in another embodiment of the present invention, each storage unit 11 comprises a weighing device (not shown) electrically connected to the controller. The weighing device can weigh the parts to be boxed of the object placing units 11, the number of boxed parts in each object placing unit 11 can be calculated based on the weight of each standard part through the weight difference before and after the parts are taken, and whether the situation of missing taking or wrong taking occurs can be further determined.

Because one storage assembly 10 includes a certain number of storage units, in actual production, the number of product accessories to be packaged in a set may be greater than the number of storage units 11 included in the previous storage assembly 10. To address this issue, optionally, in another embodiment of the present invention, the auxiliary device includes at least two placement modules 10, each placement module 10 includes a module interface (not shown), and the photoelectric sensor 112 and the indicator light 121 of each placement module 10 are electrically connected to the controller through the corresponding module interface in a pluggable manner. Therefore, the number of the object placing units 11 can be expanded, and the condition that a set of accessories to be boxed is more in actual production is met. For example, as shown in fig. one, the storage assembly 10 includes 4 storage units 11, and in a case that a set of accessories to be boxed is more than 4, a second storage assembly 10 can be inserted through the assembly interface, so as to expand the number of the storage units 11 and meet the requirement.

It should be understood that although the present description has been described in terms of various embodiments, not every embodiment includes only a single embodiment, and such description is for clarity purposes only, and those skilled in the art will recognize that the embodiments described herein may be combined as suitable to form other embodiments, as will be appreciated by those skilled in the art.

The above list of details is only for the practical examples of the present invention, and they are not intended to limit the scope of the present invention, and all equivalent embodiments or modifications, such as combinations, divisions or repetitions of the features, which do not depart from the technical spirit of the present invention, should be included in the scope of the present invention.
