Abstract

PURPOSE:To effectively eliminate the stacking of packs and make it difficult for the packs to jam by applying the constitution wherein a separation belt moving in the reverse direction of a main conveyor is so positioned as to oppose the face of a main conveyor belt with a gap corresponding to a value between one and tow packs. CONSTITUTION:When placed one after another at the starting end of a main conveyor 2, packs P as separated individually are fed in sequence to a gluing machine 10, passing the underside of the round belts 22 and so forth of a separation device 3. On the other hand, when two or more packs P placed on the face of the belt 4 of the conveyor 2 are stacked on each other, a gap (t) between the round belt 22 of the separation device 3 and the face of the conveyor belt 4 is less than thickness corresponding two packs P. Consequently, the upper pack P' is pushed back with the round belts 22 and so forth traveling in a reverse direction, and dropped to the back of the lower pack P. As a result, the lower pack P and the pack P' stacked thereon pass one after another the underside of the separation device 3, and are fed to the gluing machine 10 in sequence.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a conveying device used for supplying folded and bagged stockings to a sealing machine.

[Prior Art] Products such as pantyhose are folded thinly and packed into bags, and the flaps of the bags are folded using a pasting machine, and predetermined tapes or stickers are pasted on the edges of the flaps before being shipped. Conventionally, semi-packaged products that are still bagged (
When supplying the bag to a pasting machine for stickers, etc., the method shown in FIG. 4 was used. That is, a conveyor 60 is provided in front of the machine 10 for pasting stickers, tapes, etc., and a bag P, which is a half-packed product packed in a bag, is placed on the starting end A of the conveyor 60. Since this is done while manually packing the bags, the pitch of the bags P, ... on the conveyor 60 is not constant,
The front and rear bags often overlapped partially. For this purpose, a separation conveyor 61 is arranged between the transport conveyor 60 and the pasting machine 10, and a separation plate 62 provided on the carcass separation conveyor
The overlap was resolved by pushing down the back P' that overlapped on the upper side.

[Problems to be Solved by the Invention] However, the effect of preventing superposition by the separation conveyor 61 is not sufficient, and for example, as shown in FIG. If there is,
Since the front end of the upper bag P' is pressed down by the separating plate 62 and the brake is applied, the front end of the upper bag P' is pressed down and the bag P' is deeply submerged under the lower bag P or the upper bag P' which is in contact with the conveyance surface of the conveyor. Sometimes I got stuck in a certain position. In order to avoid this, if the distance between the separating plate 62 and the conveying surface 61a of the separating conveyor 61 is increased, the above-mentioned upper and lower bags p and p' will pass overlapping each other and become clogged inside the pasting machine 10. There was a point.

An object of the present invention is to effectively eliminate the above-mentioned polymerization and provide an apparatus that is less likely to become clogged.

Means for Solving Problem E] In order to solve the above problem, the present invention has the following configuration.

In other words, the conveyance device according to the present invention includes a main conveyor that carries objects such as bagged cloth products on a conveyance surface and conveys them in a predetermined direction, and a separating device provided above the main conveyor. , the separating device is supported above the conveying surface of the main conveyor with an interval larger than the thickness of one conveyed object and smaller than the thickness of two conveyed objects, and is supported above the conveying surface of the main conveyor, and It is characterized by having a separation belt that moves in the opposite direction to the conveyance direction of the conveyor.

[Operation] The conveyed object placed on the main conveyor is conveyed to the terminal end B side passing under the separating device. If the conveyed items are stacked one on top of the other, they will come into contact with the separation belt, so
The upper conveyed articles are pushed out in the opposite direction, and only the lower conveyed articles pass under the separating device. In this way, the vertical overlap is eliminated.

[Example] The embodiments shown in the drawings will be described below.

FIGS. 1 and 2 show one embodiment of the present invention, and this conveying device 1 consists of a main conveyor 2 and a separating device 3. FIG. The main conveyor 2 is a heald conveyor that has a heddle 4 stretched between pulleys 5° and 5', and side plates 6 and 6 installed on both sides of the belt. transport.

A round heald 22, which is a separate heald, is stretched between each of the three face 19 booths arranged in a row. That is, five round healds 22, . And 5 These round belts have a roughly diagonal shape with the bottom part almost parallel to the heald of F Koshihair 2 when viewed from the side! are doing. A gap 7 is provided between this lower area and the belt of the main conveyor 2, which is larger than the thickness of one transported object and smaller than the thickness of two transported objects.

Both ends of the horizontal frame 12 are supported by left and right support brackets 25 and 25' attached to the machine frame 2a of the main conveyor 2. A cylindrical fixture 27 is integrally provided on the support bracket 25, into which the end of the horizontal frame 12 is fitted and a set screw 28. It is fixed by... The base of the support bracket 25 is provided with elongated holes 30, 30 in the vertical direction, and is fixed to the machine frame 2a of the main conveyor 2 by bolts 31, 31 inserted therein. This bolt 31.
By loosening 31, the fixing position can be adjusted up and down along the elongated holes 30, 30. Note that the support bracket 25' on the opposite side can also be adjusted up and down in its fixing position relative to the main conveyor.

Hereinafter, the usage will be explained by taking as an example the case where the conveying device 1 is used to feed the bag P of stockings packed into bags to the machine 10 for pasting tapes, stickers, etc. When using this device, the drive motor (not shown) of the main conveyor 2 and the motor 37 of the separating device 3 are started, and the belt 4 of the main conveyor 2 and the round belt 22 of the separating device 3 are started. - and are respectively driven in the direction of the arrow. The moving speed of the round belt 22 which is the separation belt is, for example, 100 m/min, the moving speed of the belt 4 of the main conveyor is, for example, 10 m/min, and the moving speed of the round belt 22 is variable between 0 and 160 m/min. . In this state, when the bags P are placed one after another on the starting end A of the main conveyor 2, the bags P separated one by one are sequentially placed on the round belt 22 of the separating device 3. -... is supplied to the pasting machine 10 by passing under it.

-4. When two or more bags P placed on the conveyance surface of the belt 4 of the main conveyor 2 overlap vertically,
Since the gap t between the round belt 22 of the separation device 3 and the top surface (conveying surface) of the belt 4 of the main conveyor is smaller than the thickness of two bags P, the upper bag P' is moving in the opposite direction. It is pushed back backward by the round belt 22, and falls behind the bag P on the lower side. For this reason, the lower bag P and the bag P' superimposed thereon pass through the lower side of the separating device 3 back and forth, and are sequentially supplied to the pasting machine 10. This separating device 3 eliminates the overlapping of bags by means of a round belt 22 that moves in the opposite direction to the belt of the main conveyor, so for example, as shown in FIG. Even if there is a problem, it can be pushed back reliably and no blockages will occur in this area.

[Effects of the Invention] As is clear from the above description, in the conveyance device according to the present invention, the separation belt that moves in the opposite direction to the moving direction of the main conveyor for conveying articles is conveyed between the conveyance surface of the main conveyor. They are placed facing each other with a gap greater than the thickness of one object and smaller than the thickness of two objects, so when two or more objects are overlapped on the main conveyor, the upper object is It is now possible to effectively eliminate overlapping by pushing it back to the rear and letting it fall.
