FIELD OF THE INVENTION

The invention relates to a packaging device, and more particularly to a feeding device for an electrostatic bag for loading electrostatic bags.

BACKGROUND OF THE INVENTION

Solid state disks (SSDs) are smaller in size and faster to read, can be quickly accepted by users, and gradually replace mechanical hard disks. Compared to mechanical hard disks, SSDs are crash resistant, minor collisions do not result in data loss, and their service life is longer than that of mechanical hard disks. However, price of SSDs is significantly higher than that of mechanical hard disks. Once SSDs are damaged, data will be lost and cannot be retrieved. Therefore, it is necessary to properly package the SSDs.

An electrostatic bag covers the SSD to prevent static electricity from affecting the performance of the SSD. In order to automatically packaging the electrostatic bag outside the SSD, there is an urgent need for an automatic feeding device for an electrostatic bag that can supply an electrostatic bag to the SSD.

SUMMARY OF THE INVENTION

One objective of the present invention is to provide a feeding device for an electrostatic bag for supplying electrostatic bags to a package mechanism, so as to automatically pack the electrostatic bag outside the solid state disk and avoid damaging the solid state disk due to the manual operation, thereby improving production efficiency.

To achieve the above objective, a feeding device for an electrostatic bag is provided, adapted for supplying electrostatic bags to a package mechanism, which includes two carrying mechanisms arranged up and down, respectively for supporting a tray with an electrostatic bag. The feeding position of the feeding device for an electrostatic bag is between the two carrying mechanisms and towards the package mechanism. The two carrying mechanisms are moved up and down to switch positions.

In comparison with the prior art, the feeding device for an electrostatic bag can supply the electrostatic bag to the package mechanism so as to pack an electrostatic bag outside the solid state disk. Two carrying mechanisms arranged up and down on the feeding device for an electrostatic bag can move up and down to switch positions. When the electrostatic bags of the carrying mechanism at the upper electrostatic bag supply position are used up, the two carrying mechanisms move up and down and switch positions. So another carrying mechanism is positioned at the upper electrostatic bag supply position, and the electrostatic bag is supplied to the package mechanism via a new tray. Therefore, the feeding device for an electrostatic bag can supply electrostatic bags to a package mechanism, reload the electrostatic bag without stopping the machine, and ensure the continuous operation of the package mechanism.

Preferably, a position switching mechanism is disposed between the two carrying mechanisms. When one of the carrying mechanisms is moved towards another of the carrying mechanisms, another of the carrying mechanisms is correspondingly moved under the action of the position switching mechanism to switch the two carrying mechanisms.

Concretely, the position switching mechanism is an inter-mesh rack mechanism.

Concretely, the feeding device for an electrostatic bag further includes a switching drive mechanism, for driving the two carrying mechanisms to move vertically.

Preferably, the feeding device for an electrostatic bag further includes a driving mechanism for driving at least one carrying mechanisms to move in a horizontal direction, so that when the two carrying mechanisms move up and down to switch position, the two carrying mechanisms avoid collision.

Preferably, the driving mechanism drives the carrying mechanism located on the upper side to move in horizontal direction, so that projections of the two carrying mechanisms in the horizontal plane are staggered. So it can avoid interference when two carrying mechanisms move up and down to switch position.

Preferably, the carrying mechanism includes a positioning rod, for positioning the tray, and a tension rod disposed between the positioning rod and the package mechanism.

Preferably, the carrying mechanism further includes a drive member, for driving the positioning rod to rotate to drive the tray to rotate.

Preferably, the feeding device for an electrostatic bag further includes a feeding bracket disposed on the feeding position, for transporting the electrostatic bag to the package mechanism.

Preferably, the feeding bracket is provided with a clamping mechanism, for clamping and positioning the electrostatic bag.

DETAILED DESCRIPTION OF ILLUSTRATED EMBODIMENTS

A distinct and full description of the technical solution of the present invention will follow by combining with the accompanying drawings.

Referring to FIGS. 1-4, the electrostatic bag package production line for solid state disk (SSD) is used to pack an electrostatic bag S on a solid state disk Q. The electrostatic bag package production line for solid state disk includes a solid state disk feeding mechanism 400, a connecting finger device 500, a delivery device 600, and a solid state disk unloading mechanism 900. Besides, the electrostatic bag package production line for solid state disk further includes a sealing device for an electrostatic bag on one side of the delivery device 600. Concretely, the sealing device for an electrostatic bag includes a package mechanism 700 and a sealing mechanism 800 arranged in sequence along the conveying direction of the delivery device 600; and several detection mechanisms are also provided on the delivery device 600, to detect the solid state disk Q. Reference to FIGS. 5-8, more specific:

As shown in FIGS. 1-4, the electrostatic bag package production line for solid state disk includes a main frame 100, a solid state disk feeding mechanism 400 disposed above the main frame 100, a connecting finger device 500, a delivery device 600, and a package mechanism 700, a sealing mechanism 800, and a solid state disk unloading mechanism 900. A tray feeding mechanism 300 is provided outside one end of the main frame 100 and at the beginning of the conveying direction of the delivery device 600. And, a tray unloading mechanism 1000 is provided outside the other end of the main frame 100 and at the end of the conveying direction of the delivery device 600. Specifically, a control component such as a motor, a control circuit, a PLC, and the like are disposed under the main frame 100. Meanwhile, the aforementioned multiple mechanisms and devices are respectively disposed above the main frame 100, and a housing 200 is also disposed outside the main frame 100. The housing 200 covers the aforementioned multiple mechanisms and devices provided above the main frame 100. Besides, the housing 200 is also provided with an operation panel, a monitor, and the like, so as to monitor and operate the electrostatic bag package production line for solid state hard disk.

As shown in FIG. 2 to FIG. 4, above the main frame 100, a first delivery device 610 and a second delivery device 620 are arranged in parallel along the length direction of the main frame 100. The first delivery device 610 and the second delivery device 620 move at the same direction, and transport the tray from one end near the tray feeding mechanism 300 to the other end near the tray unloading mechanism 1000. The first delivery device 610 and the second delivery device 620 respectively transport different specifications solid state disks. For example, the first delivery device 610 conveys M2 solid state disks, and the second delivery device 620 conveys 2.5 solid state disks. In this embodiment, the electrostatic bag package production line for solid state disk packs a 2.5 solid state disk with an electrostatic bag and transports the 2.5 solid state disk via the second delivery device 620. The M2 solid state disk transported via the first delivery device 610 is scanned and discharged.

Preferably, the 2.5 solid state disk is transferred to the second delivery device 620, and then passes through the package mechanism 700 and is packed with an electrostatic bag. Subsequently, the 2.5 solid state disk passes through the sealing mechanism 800 and is sealed. More specific:

As shown in FIGS. 2-4, the electrostatic bag package production line also includes a feeding device for an electrostatic bag 1700. The feeding device for an electrostatic bag 1700 is disposed on the side of the package mechanism 700 facing away from the second delivery device 620. The feeding device for an electrostatic bag 1700 is used for supplying electrostatic bags to the package mechanism 700 so as to pack an electrostatic bag outside the solid state disk. As shown in FIG. 5, the number of the feeding device for an electrostatic bag 1700 is two, and the two feeding devices for an electrostatic bag 1700 directly face the package mechanism 700. Specifically, the two feeding device for an electrostatic bag 1700 directly faces the electrostatic bag package position of the package mechanism 700. The carrying mechanism 1710 is disposed on a side of the feeding device 1700 for an electrostatic bag away from the package mechanism 700, and the tray with an electrostatic bag can be conveniently loaded onto the carrying mechanism 1710. It can be understood that the electrostatic bag is in the shape of a long tube and open at both ends. Concretely, the electrostatic bag is pressed into a flat structure to form a long band and is wound around the tray. The front end of the electrostatic bag has an opening and extends toward the package mechanism 700. With the package mechanism 700 pulling, the tray at the carrying mechanism 1710 rotates, the electrostatic bag gradually moves to the package mechanism 700, and is packed outside the solid state disk and cut to a certain length.

As shown in FIGS. 5-8, the feeding device for an electrostatic bag 1700 includes two carrying mechanisms 1710 arranged up and down, and a feeding position 1700c of the feeding device 1700 is between the two carrying mechanisms 1710 and facing the package mechanism 700. The two carrying mechanisms 1710 are respectively used for carrying the tray P with electrostatic bag. Furthermore, the two carrying mechanisms 1710 can be moved up and down to switch positions. Therefore, when the electrostatic bags of the carrying mechanism 1710 at the upper electrostatic bag supply position 1700a are used up, the two carrying mechanisms move up and down and switch positions. So another carrying mechanism 1710 is positioned at the electrostatic bag supply position 1700a at the upper side, and the electrostatic bag is supplied to the package mechanism 700 via a new tray. Therefore, the feeding device for an electrostatic bag can supply electrostatic bags to a package mechanism 700, reload the electrostatic bag without stopping the machine, and ensure the continuous operation of the package mechanism 700.

It can be understood, although the two carrying mechanisms 1710 located on the upper and lower sides can both supply the electrostatic bags to the package mechanism 700, the electrostatic bags on the carrying mechanism 1710 located on the upper side can be pulled out to feed more conveniently. But it is not convenient for the operator to load and unload tray from the upper carrying mechanism 1710 at the same time. In actual use, the position on the upper side is regarded as the electrostatic bag supply position 1700a, and the position on the lower side is regarded as an electrostatic bag preparation position 1700b.

During use, before the electrostatic bags of the carrying mechanism 1710 on the electrostatic bag supply position 1700a are used up, the end opening of the electrostatic bag is connected to the front end opening of the electrostatic bag on another carrying mechanism 1710 on the electrostatic bag preparation position 1700b. Thus, the end of the electrostatic bag on the previous tray is connected with the starting end of the electrostatic bag on the following tray, which is a continuous structure, so the electrostatic bags are continuously sent to the package mechanism 700 to continuously operate the package mechanism 700. At this point, the empty tray can be removed and the new tray is reloaded at the carrying mechanism 1710.

Since the carrying mechanism 1710 can move up and down alternately, when the electrostatic bags on the upper carrying mechanism 1710 is used up, the end opening of the electrostatic bag is connected with the front end opening of the electrostatic bag on another lower carrying mechanism 1710. After the front opening of the electrostatic bag is connected, the positioning mechanism on the lower side can move upward to the electrostatic bag supply position 1700a, and the original positioning mechanism on the upper side moves downward to the electrostatic bag preparation position 1700b.

Preferably, as shown in FIG. 6 and FIG. 7, in order to switch the two carrying mechanisms 1710, a position switching mechanism 1720 is disposed between the two carrying mechanisms 1710 to switch the two carrying mechanisms 1710. When the carrying mechanism 1710 is urged to move towards the other carrying mechanism 1710, the other carrying mechanism 1710 moves correspondingly under the action of the position switching mechanism 1720 to switch the two carrying mechanisms 1710. More specifically, the position switching mechanism 1720 may be an inter-mesh rack mechanism or other mechanisms that can realize the vertical staggered movement of the two carrying mechanisms 1710.

Referring to FIG. 6 and FIG. 7, the feeding device for an electrostatic bag 1700 further includes a switching drive mechanism 1740 for driving the two carrying mechanism 1710 to move vertically. It can be understood, the two switching drive mechanism 1740 drives only one of the two carrying mechanisms 1710. When the carrying mechanism 1710 is located on the electrostatic bag preparation position 1700b at the lower side, the switching drive mechanism 1740 drives the carrying mechanism 1710 to move up to the electrostatic bag supply position 1700a, thereby supplying the electrostatic bags to the package mechanism 700. When the carrying mechanism 1710 is located on the electrostatic bag supplying position 1700a at the upper side, and when electrostatic bag is used up and it needs to switch position, the switching drive mechanism 1740 drives the carrying mechanism 1710 to move to the electrostatic bag preparation position 1700b to remove the empty tray and reload the tray with the electrostatic bag. In the process of driving the carrying mechanism 1710 by the switching drive mechanism 1740, the other carrying mechanism 1710 moves itself to the target position by the position switching mechanism 1720.

It can be understood that the two carrying mechanisms 1710 are arranged up and down to prevent the two carrying mechanisms 1710 from interfering with each other. The feeding device for an electrostatic bag 1700 also includes a driving mechanism 1730 for driving at least one two carrying mechanisms 1710 to move in a horizontal direction. Specifically, in this embodiment, the driving mechanism 1730 drives the carrying mechanism 1710 on the upper side away from the feeding position 1700c, so that projections of the two supporting mechanisms in the horizontal plane are staggered.

Referring to FIG. 8, the carrying mechanism 1710 includes a positioning rod 1711 for positioning the tray, and a tension rod 1712 disposed between the positioning rod and the package mechanism 700. The tension rod 1712 can stop pulling the electrostatic bag, so that the electrostatic bag maintains an average degree of tightness to avoid deformation of the electrostatic bag due to excessive local force. The carrying mechanism 1710 also includes a drive member 1750 for driving the positioning rod 1711 to rotate to drive the tray to rotate.

Referring to FIGS. 5-7, the feeding device for an electrostatic bag 1700 includes a feeding bracket 1760. The feeding bracket 1760 is disposed at the feeding position 1700c of the two carrying mechanisms 1710, for transporting the electrostatic bag to the package mechanism. Specifically, the feeding bracket 1760 is further provided with a clamping mechanism 1761 for clamping and positioning the electrostatic bag.

Referring to FIGS. 2-4, under the action of the package mechanism 700, the electrostatic bag, which is fed to the package mechanism 700, is placed outside the corresponding solid state disk, and is individually cut to a size corresponding to the solid state disk. Subsequently, the solid state disk with the electrostatic bag moves along the second delivery device 620 to the sealing mechanism 800 for sealing electrostatic bag; and the sealing mechanism 800 heat-seals the solid state disks. The solid state disk packaged with the electrostatic bag is then unloaded via the solid state disk unloading mechanism 900 and the tray unloading mechanism 1000.

As shown in FIGS. 1-8, the working process of the feeding device for an electrostatic bag 1700 according to this embodiment is described in detail:

The operator places the tray P with the electrostatic bag to the carrying mechanism 1710 at the electrostatic bag preparation position 1700b, and is reliably positioned by the positioning rod 1711; the front end of the electrostatic bag passes through several tension rods 1712 and reaches the feeding position 1700c;

The switching drive mechanism 1740 drives the carrying mechanism 1710 to move upward to the electrostatic bag supply position 1700a; meanwhile, the position switching mechanism 1720 drives the other carrying mechanism 1710 located at the electrostatic bag supply position 1700a to move down to the electrostatic bag preparation position 1700b;

The package mechanism 700 starts and drags the front end of the electrostatic bag; at the same time, the driving mechanism 1730 drives the positioning rod 1711 to rotate, thereby loading the electrostatic bag; the operator can then place the tray P with the electrostatic bag to the carrying mechanism 1710 at the electrostatic bag preparation position 1700b;

Before the electrostatic bags of the carrying mechanism 1710 on the electrostatic bag supply position 1700a are used up, the end opening of the electrostatic bag is connected to the front end opening of the electrostatic bag on another carrying mechanism 1710 on an electrostatic bag preparation position 1700b; thus, the end of the electrostatic bag on the previous tray is connected with the starting end of the electrostatic bag on the following tray, which is a continuous structure, so the electrostatic bags are continuously sent to the package mechanism 700 to continuously operate the package mechanism 700; and

Then, the switching drive mechanism 1740 switches the positions of the two carrying mechanisms 1710; the above operation is repeated.

In comparison with the prior art, the feeding device for an electrostatic bag 1700 can supply the electrostatic bag to the package mechanism 700 so as to pack an electrostatic bag outside the solid state disk. Two carrying mechanisms 1710 arranged up and down on the feeding device for an electrostatic bag 1700 can move up and down to switch positions. When the electrostatic bags of the carrying mechanism 1710 at the upper electrostatic bag supply position 1700a are used up, the two carrying mechanisms 1710 move up and down and switch positions. So another carrying mechanism 1710 is positioned at the upper electrostatic bag supply position 1700a, and the electrostatic bag is supplied to the package mechanism 700 via a new tray. Therefore, the feeding device for an electrostatic bag 1700 can supply electrostatic bags to a package mechanism 700, reload the electrostatic bag without stopping the machine, and ensure the continuous operation of the package mechanism 700.

While the invention has been described in connection with what are presently considered to be the most practical and preferred embodiments, it is to be understood that the invention is not to be limited to the disclosed embodiments, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.
