Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention is a product inverter that can invert a product having a narrow diameter part and a large diameter part, such as a glass stopper of a Western liquor bottle, and return it to the original position on a conveyor. It is related to the device.

0002

[Prior Art] In the manufacturing process of glass stoppers,
The stopper is transported by a conveyor in a stable position with its large diameter part facing down, and sent into the inspection line. However, since the stopper is attached to the bottle with the main body facing up, the top surface is required to have no defects in appearance. To do this, conventionally, inspectors would pick up the stopper from the conveyor, turn it upside down, inspect the top, and then return it to its original position on the conveyor. However, with this testing method, it is difficult to test 50 or more pieces per minute, and there is a problem in that testing errors are likely to occur. Therefore, sampling inspections were carried out out of necessity, but it was not possible to avoid the introduction of defective products.

0003

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems by automatically picking up a product having a small diameter part and a large diameter part, such as a stopper, from a conveyor and inverting the product.
This was completed in order to provide a product reversing device that can return the product to its original position on the conveyor.

0004

[Means for solving the problem] The above problem is solved by the above-mentioned problem.
A pulley that rotates in a vertical plane is provided, and a pair of endless belts are hung between these pulleys to sandwich and hold the narrow diameter part of the product from both sides. A product reversing device characterized by having a take-in belt that pinches and lifts the product from both sides, and a take-out belt that pinches the large diameter part of the product from both sides and returns it to the conveyor at the descending end of this endless belt. It can be solved by the device.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained in more detail below with reference to illustrated embodiments. In Fig. 1, 1 is a small diameter part 2 and a large diameter part 3.
It is a product like a glass stopper, and is placed on the upper surface of a conveyor 20 with the narrow diameter portion 2 facing upward and is transported to the left in the drawing. Above the conveyor 20, four shafts 4a, 4b, 4c, and 4d are provided horizontally. The shaft 4a is a driving shaft driven by the motor 5, and the shaft 4d is a driven shaft. Also, the intermediate shaft 4b,
4c is a floating shaft that can rotate freely.

As shown in FIG. 3, the shaft 4a is composed of two shafts separated on the left and right, and a small diameter pulley 6a and a large diameter pulley 7a are attached to each separated shaft. These left and right shafts 4a are connected to a power transmission shaft 8 above them by chains 9, 10, and are driven by a motor 5 to rotate clockwise in FIG. 1 at the same speed.

Similarly, the driven shaft 4d has a small diameter pulley 6d and a large diameter pulley 7d on two shafts separated to the left and right.
It is attached with. Furthermore, the intermediate floating shafts 4b, 4
Each of the pulleys c has two small diameter pulleys 6b and 6c and one large diameter pulley 7b and 7c. A pair of endless belts 11 are placed between the small diameter pulleys 6a to 6d on each axis. The pair of endless belts 11 can support the product 1 by sandwiching the narrow diameter portion 2 between them. Note that between the floating shafts 4b and 4c, the endless belt 11 is lifted slightly upward by two sets of pulleys 12, and this portion is used as a supply and take-out zone for the product 1.

[0008] A take-in belt 13 is provided between the shafts 4c and 4d located at the end of the endless belt 11 on the rising side, for holding and lifting the large diameter portion 3 of the product 1 from both sides. The intake belts 13 are a pair of left and right ones, and the one on the upper front side in the drawing is hung parallel to the endless belt 11 between the large diameter pulley 7c of the shaft 4c and the large diameter pulley 7d of the shaft 4d. There is. However, the remaining one is shown in Figure 2.
As shown in FIG. 4, it is hung between a large-diameter pulley 7f on a shaft 4f and a large-diameter pulley 7d on a shaft 4d, which are provided at a slight inclination toward the back of the shaft 4c. Therefore, the large diameter portion 3 of the product 1 is connected to the intermediate pulley 1 provided between the shaft 4c and the shaft 4d.
Two intake belts 13 are installed in the part closer to the axis 4d than the
It will be pinched from the left and right by the conveyor 20 and lifted from the conveyor 20. Note that 15 is an arc-shaped scraper provided to ensure that the product 1 is lifted from the conveyor 20.

Further, at the shaft 4a and shaft 4b located at the lower end of the endless belt 11, there is a take-out belt 16 which sandwiches the large diameter portion 3 of the product 1 from both sides and returns it onto the conveyor 20.
is provided. This take-out belt 16 is also a pair of left and right, and like the above-mentioned take-in belt 13, the one on the near side is connected to the large diameter pulleys 7a and 7b of the shafts 4a and 4b.
The endless belt 11 is hung in parallel between them, but the remaining one is a large-diameter pulley 7e on a shaft 4e that is slightly inclined toward the back of the shaft 4b, and a large-diameter pulley 7d on a shaft 4d. It is hung with an intermediate pulley 17 interposed therebetween.

[Operation] To use the product reversing device of the present invention constructed as described above, the product 1 is placed on the conveyor 20 with its narrow diameter portion 2 facing upward, as shown in FIG. It is fed between a pair of endless belts 11 from the part between them. The narrow diameter portion 2 of the product 1 is first sandwiched from the left and right by a pair of endless belts 11 near the shaft 4c, and then moves toward the left in the drawing. At the position of the shaft 4c, one side of the take-in belt 13 is located away from the product 1 due to the action of the large-diameter pulley 7f of the tilted shaft 4f, but as the product 1 advances, it gradually moves to the take-in belt 13 on the near side. When it approaches and comes to the part closer to the shaft 4d than the intermediate pulley 14, the large diameter part 3 of the product 1 is held between both sides. For this purpose, the product 1 is lifted off the conveyor 20 with the aid of the scraper 15 and turned upside down.

The inverted product 1 is a pair of endless belts 11
It is sandwiched between the return side (upper side) of and moves to the right in FIG. Note that at a position to the right of the intermediate pulley 14, the holding of the large diameter portion 3 by the take-in belt 13 is released, but the holding of the large diameter portion 2 is released.
Since it is stably held by the pair of endless belts 11, it continues to move to the right. During this time, the top surface of the product 1 is inspected by the inspector.

When the product 1, which has progressed to the right in this manner, passes the intermediate pulley 17, the take-out belt 16 holds the large diameter portion 3 of the product 1 from both sides from the left and right sides, as described above. On the other hand, the product 1 is reversed and returned to its original position on the conveyor 20. The product 1 separates from the endless belt 11 at the portion where the endless belt 11 is lifted by the pulley 12.

[0013]

As described above, according to the product reversing device of the present invention, the product 1 having the small diameter portion 2 and the large diameter portion 3 can be transferred to the conveyor 2.
Since it can be automatically lifted from above 0, turned upside down, and returned to the original position on the conveyor 20, for example, when visually inspecting both the top and back of a glass stopper. The inspection speed can be improved because it does not require manual reversal as in the conventional method. Further, in the product reversing device of the present invention, the large diameter portion 3 is reliably held by the take-in belt 13 and the take-out belt 16 at the portion where the product 1 is reversed and returned to its original position, so the product 1 is held stably. There is no risk of handling errors such as the product 1 falling. Therefore, the present invention greatly contributes to the industry as a product reversing device that solves the problems of the conventional products.
